Description

FIELD OF THE INVENTION The present invention relates to a garment processing device. More specifically, the present invention relates to a clothing processing apparatus that includes a drive unit that is directly connected to a drum that accommodates clothing and rotates the drum.

Clothes processing devices are devices that remove dust or foreign substances from clothes by applying physical force to the clothes, and include washing machines, dryers, refreshers (stylers), and the like.

A washing machine performs a washing process by supplying water and detergent to clothes to separate and remove foreign substances from the clothes.

Dryers are classified into exhaust type dryers and circulation type dryers, and they commonly perform a drying process in which high-temperature hot air is produced by a heater and exposed to the clothes to remove moisture from the clothes.

Recently, dryers have been designed to perform the drying process intensively, omitting the structure for supplying water to and draining the clothes, and also omitting the tub for storing water in the cabinet. This makes it possible to simplify the structure inside the dryer and improve drying efficiency by directly supplying hot air to the drum that accommodates clothes.

Such a dryer includes a drum for storing clothes, a hot air supply section for supplying hot air to the drum, and a drive section for rotating the drum. Thereby, the dryer can supply hot air into the drum to dry the clothes stored in the drum, and rotate the drum to uniformly expose the surface of the clothes to the hot air. As a result, the entire surface of the clothing is evenly contacted with the hot air, and drying can be completed.

On the other hand, in order for the drive unit to rotate the drum, it needs to be fixed within the cabinet. Further, when the drive unit rotates the rotation shaft coupled to the drum, it is necessary to connect the drive unit parallel to the rotation shaft. However, since the dryer does not have a fixed tab inside the cabinet, there is a limitation in that the drive unit cannot be fixed to the tub like a washing machine.

To solve this problem, a dryer in which the drive unit is fixed to the back of the cabinet has been introduced [Japanese Patent Publication JPS55-081914A, Japanese Patent Publication JPS55-115455A, Japanese Patent Publication JPS57-063724A, Japanese Patent Publication No. See JPS57-124674A].

FIG. 1 shows the structure of a conventional dryer in which the drive unit is coupled to the back of the cabinet.

This dryer includes a cabinet 1 that forms the exterior, a drum 2 that is rotatably provided in the cabinet 1 and stores clothes, and a drive unit 3 that rotates the drum 2.

The driving unit 3 is disposed on the back side of the drum 2 to rotate the drum 2, or is coupled and fixed to a back panel 11 forming the back side of the cabinet 1. Thereby, the drive unit 3 is fixed to the cabinet 1 and can rotate the drum 2.

The drive unit 3 of the conventional dryer described above commonly includes a stator 31 fixed to the back panel 11, a rotor 32 rotated by the stator 31, and a rotating shaft 33 coupled with the rotor 32 to rotate the drum 2. , includes a speed reducer 37 that rotates the drum 2 by increasing the torque while decreasing the rpm of the rotating shaft 33.

Further, the conventional dryer further includes a fixing part 4 for fixing the driving part 3 to the rear panel 11. The fixing section 4 includes either a first fixing section 41 that fixes the stator 31 to the back panel 11 and a second fixing section 42 that fixes the rotating shaft 33 to the back panel 11. Accordingly, in the conventional dryer, the rotating shaft 33 coupled to the drum 2 and the drive unit 3 are arranged in parallel, and the drum 2 can be rotated stably.

However, since the back panel 11 of the cabinet is made of a thin steel plate, it easily deforms or vibrates even under very small external forces. In addition, since not only the load of the drive unit 3 but also the load of the drum 2 is transmitted to the rear panel 11 via the rotating shaft 33, it is difficult to maintain the shape.

Furthermore, if the clothes are eccentric in the drum 2 or repeatedly fall into the drum 2 during the rotation process, external force is repeatedly transmitted to the back panel 11, causing the back panel 11 to vibrate.

If vibration or external force is transmitted to the back panel 11 and the back panel 11 bends or deforms even temporarily, a problem may occur in which the rotating shaft 33 connecting the drive unit 3 and the drum 2 is twisted. This causes unnecessary vibrations and noise to occur in the drive unit 3, and in severe cases, the rotating shaft 33 may be damaged. There is also the problem that unnecessary noise is generated during the process of bending or deforming the back panel 11.

In addition, during the process of vibration of the back panel 11, the distance between the rotor 32 and the stator 31 is temporarily changed, causing the rotor 32 to collide with the stator 31, causing unnecessary vibrations and noise.

Further, when the drive unit 3 further includes a speed reducer 37, the rotating shaft 33 coupled to the speed reducer 37 and the speed reduction shaft 33a connected from the speed reducer 37 to the drum 2 are separated from each other. At this time, since the reducer 37 is supported by the back panel 11 via the stator 31 and the rotating shaft 33, if the back panel 11 is even slightly deformed, a problem occurs in which the reducing shaft 33a and the rotating shaft 33 are twisted or misaligned. It is possible.

In other words, the amount of change in position of the deceleration shaft 33a connected to the drum 2 due to the load of the drum 2 is smaller than that of the rotating shaft 33 connected to the drive unit 3. Therefore, when the back panel 11 is temporarily bent or deformed, the degrees of inclination of the rotating shaft 33 and the decelerating shaft 33a are different, and the rotating shaft 33 and the decelerating shaft 33a are misaligned.

Therefore, in the conventional clothing processing apparatus, the rotation shaft 33 and the reduction shaft 33a are misaligned each time the drive unit 3 operates, and not only the reliability of the reduction gear 37 cannot be guaranteed, but also the reduction gear 37 may be damaged.

On the other hand, in order to directly connect the drive unit 3 to the drum 200 in the dryer, it is necessary to connect a rotating shaft that transmits the power of the drive unit 3 to the drum 200. However, as described above, in the conventional dryer, a specific structure for coupling the drive section 3 to the drum 200 is not specified, and a structure for coupling the drum 200 and the drive section 3 of a washing machine cannot be applied. Conceivable.

FIG. 2 is a diagram showing a dryer in which the drive unit is fixed to the bottom surface or base of the cabinet 1.

The dryer includes a cabinet 1 and a drum 2, a circulation passage 5 for circulating air in the drum 2 to the outside, and a heat pump 6 housed in the circulation passage 5 for condensing and reheating the air. Water condensed by the heat pump 6 is collected in a water storage tank 9 using a pump 8.

On the other hand, even if vibration occurs in the drive unit 3 or external force is temporarily transmitted through the drive unit 3, the bottom surface 12 of the cabinet 1 can be prevented from being deformed or tilted.

Therefore, in the conventional dryer, the drive unit 3 is disposed on the bottom surface 12 of the cabinet 1 or below the drum 2, and is fixed to a base or the like fixed to the bottom surface of the cabinet 1. In such a dryer, since the drive unit 3 is not arranged parallel to the rotation axis of the drum 2, another configuration is further used to rotate the drum 2.

Specifically, the drive unit 3 includes a motor unit 34 fixed to the bottom surface of the cabinet 1, a rotating shaft 37 that rotates in the motor unit 34, a pulley 35 that rotates by the rotating shaft 37, and an outer peripheral surface of the drum 2 and the pulley. and a belt 36 connecting the outer circumferential surfaces of 35.

Thereby, when the motor section 34 rotates the rotating shaft 37, the pulley 35 rotates the belt 36, and the belt 36 rotates the drum 2. At this time, since the diameter of the pulley 35 is much smaller than the diameter of the drum 2, the dryer can omit a speed reducer.

However, in such a dryer, since the diameter of the pulley 35 is much smaller than the diameter of the drum 2, when the motor unit 34 rotates quickly, a slipping phenomenon occurs in which the belt 36 slips on the drum 2 and the pulley 35. Therefore, such a dryer has the problem of limiting the rotational speed of the motor section 34 to below a certain level, and the fundamental problem is that the motor section 34 must be gradually accelerated or decelerated to prevent the belt 36 from slipping when the drum 2 rotates. There are limits.

Therefore, the conventional dryer cannot quickly change the rotation direction of the drum 2 and cannot control the rotation of the drum 2 or cannot change the rotation direction of the drum 2.

Therefore, this dryer has a limitation in that the rotational direction and rotational speed of the drum 2 cannot be controlled as intended during the drying process, and the drying efficiency cannot be maximized.

An object of the present invention is to provide a clothing processing device that can maintain a motor that provides rotational power to rotate a drum and a rotation shaft of a reducer that converts the rpm and torque of the rotational power.

SUMMARY OF THE INVENTION An object of the present invention is to provide a clothes processing device in which the speed reducer and the motor can tilt or vibrate simultaneously.

SUMMARY OF THE INVENTION An object of the present invention is to provide a clothes processing device in which a speed reducer and a motor are separated from and fixed to the back of a cabinet.

SUMMARY OF THE INVENTION An object of the present invention is to provide a clothing processing device in which a rotation shaft of a drum and a drive shaft of a drive unit are aligned or fixed with respect to a speed reducer.

SUMMARY OF THE INVENTION An object of the present invention is to provide a clothing processing device in which a reducer is fixed in a cabinet and a drive section is fixed and supported by the reducer.

An object of the present invention is to provide a clothing processing device in which a drive shaft that extends from a motor and rotates, and a rotation shaft of a speed reducer that rotates by converting the RPM and torque of the rotation shaft can be maintained coaxially.

An object of the present invention is to provide a clothing processing device that can control the rotational speed and direction of the drum even if the tab is omitted.

An object of the present invention is to provide a clothing processing device in which a speed reducer can be firmly fixed.

An object of the present invention is to provide a clothing processing device in which a distance between a rotor and a stator in a motor is maintained.

The present invention provides a clothing processing apparatus in which a motor unit that provides power to rotate a drum and a speed reducer that converts the power of the motor unit are combined.

The motor part may be directly coupled and supported by the reducer, or may be coupled and supported only by the reducer. As a result, the reducer itself becomes the vibration reference for the motor section.

A stator, which generates a rotating magnetic field in a motor part, is coupled and fixed to a housing that forms the appearance of the reducer.

The reducer housing is coupled to and supported by a rear cabinet coupled to the rear surface of the drum. However, the stator may be arranged separately from the rear cabinet or may be provided separately from the rear cabinet.

The speed reducer housing is at least partially inserted into the internal space of the stator or is disposed within the stator. Thereby, the space occupied by the speed reducer alone can be reduced by utilizing the internal space of the stator.

Furthermore, by directly coupling the stator to the reducer housing and positioning the reducer housing inside the stator, the center of the rotor rotated by the stator can be easily aligned with the center of the reducer.

As a result, in the garment processing device according to the invention, the drum, speed reducer, stator and rotor form one vibration system. A speed reducer is coupled to the stator and a speed reducer is coupled to the drum. Therefore, the reducer, stator, and drum can integrally form a vibration system.

The drum, stator and rotor are separated and spaced apart from the rear cabinet.

That is, the drum, stator, and rotor are tilted in parallel around the reducer and vibrate together.

The reducer serves as the point of action of the lever or seesaw in the vibration system, and since the reducer is supported by the rear cabinet, the rear cabinet can serve as the point of action.

On the other hand, the drum is made of a soft material so that its shape can be changed to some extent, and the drum is made of an elastic material so that its shape can be restored. Also, a part of the connecting shaft connecting the drum and the speed reducer may be made of a soft material.

In this case, the drum can be moved independently forming a vibration system different from the reducer and stator/rotor. This can prevent external forces from being transmitted to the stator and motor section in the event that a severe imbalance occurs within the drum or transient vibrations occur within the drum.

On the other hand, the reducer and motor are separated from the external cover (rear panel) for vibration reasons.

In other words, the reducer and motor are spaced apart from the back panel of the cabinet.

That is, the reducer and motor are fixed and coupled to each other, but are completely separated from the back panel.

Of course, the speed reducer and the motor can be supported while being coupled to at least the back panel, but they do not need to be coupled to the back panel by a fixing member or the like.

Therefore, the reducer and motor are not affected by changes in shape or vibration of the rear panel, and coaxiality is maintained based only on the reducer.

That is, the entire drive train remains coaxial and tilts or oscillates together.

Specifically, the reducer and the motor are fixed to each other in order to maintain maximum concentricity between the rotor axis and drum axis of the two-axis reducer.

If concentricity is not formed, not only the reliability of the speed reducer itself will be greatly reduced, but also the spacing between the stator and rotor will not be maintained constant, causing unnecessary noise and vibration.

Therefore, by coupling the stator to the reducer housing, the reducer serves as a reference for coupling, and the center of the reducer can be aligned with the center of the stator. As a result, the reliability of the reducer can be guaranteed. Additionally, since the drum shaft and rotor shaft can be maintained concentrically, the gap between the rotor and stator can always be maintained.

The clothing processing device according to the present invention includes a drum and a motor section disposed behind the drum, and a rear cabinet disposed between the drum and the motor, coupled to the rear cabinet to transmit power of the motor section to the drum. including a reduction gear.

The clothing processing apparatus according to the present invention includes a front stopper that rotatably supports the front of the drum, and also includes a rear stopper arranged at the rear of the drum.

The rear stopper contacts the back of the drum and supports the rear of the drum.

The rear stopper is spaced apart from the back surface of the drum by a standard distance (for example, 2 mm). This is to prevent wear on the rear slopper and to support the drum only if the drum is heavy.

The rear cabinet and the back of the drum are spaced apart by a standard distance or more.

The rear stopper is arranged between the rear cabinet and the drum, and the rear stopper supports the lower end of the drum. The rear stopper consists of a roller structure/felt structure.

The rear cabinet is placed between the reducer or motor section and the drum. The rear cabinet is arranged between the rear stopper and the speed reducer or motor section.

The rear cabinet is thicker and more rigid than the front cabinet or rear cover.

In the present invention, the belt for rotating the drum is omitted, and a driving unit is directly connected to the rear of the drum to rotate the drum. Therefore, a structure for installing and supporting the drum and drive unit is additionally required.

At this time, the rotating shaft connecting the drum and the drum in the driving section rises or tilts during rotation.

A driving section including a reduction gear is connected and fixed to the rear of the rear plate. As a result, the drum is disposed in front of the rear plate, and the drive section is disposed behind the rear plate, thereby dispersing the weight of the rear plate.

Since the rear plate itself supports the load of the drum or drive unit, the load is not only distributed in front and behind the rear plate, but also the rear plate can serve as the point of action of the seesaw.

This causes the drum and drive unit to tilt and vibrate while maintaining coaxial alignment.

On the other hand, since the rear plate is made of a strong plate, a bracket is provided that is connected to the rear plate and can reinforce the rigidity of the rear plate.

The bracket is made up of one or more rings and is formed into a ring shape to connect the reducer and the rear plate.

The brackets are also placed in front and behind the rear plate, respectively, so that the reducer can be stably connected to the rear plate, and the rigidity of the rear plate can be strengthened.

When the bracket is composed of a plurality of brackets, any of the brackets is used to connect the reducer and the rear plate to strengthen the rigidity of the rear plate, and the other brackets are used to strengthen the coupling force of the reducer.

A motor providing rotational force for rotating the drum and a rotating shaft of a reducer converting the rotational force into RPM and torque can be maintained.

The reducer and motor can tilt and vibrate at the same time.

The present invention has the effect that the reducer and the motor are fixed apart from the back of the cabinet.

The present invention has the effect of providing a clothing processing device in which the rotation shaft of the drum and the drive shaft of the drive unit are aligned or fixed with respect to a speed reducer.

The present invention has the effect that the reducer is fixed in the cabinet and the drive section is fixed and supported by the reducer.

The present invention has the advantage that the drive shaft that extends from the motor and rotates, and the rotation shaft of the reducer that rotates by converting the RPM and torque of the rotation shaft can be maintained coaxially.

The present invention has the advantage of being able to control the rotational speed and direction of the drum in a clothing processing device that does not include a tab.

The present invention has the effect of firmly fixing the reducer.

The present invention has the effect of maintaining the distance between the rotor and the stator in the motor.

Hereinafter, embodiments described in this specification will be described in detail with reference to the accompanying drawings. In this specification, even if the embodiments are different from each other, the same or similar configurations will be given the same or similar reference numerals, and the description thereof will be omitted. As used in the present invention, the singular expression includes the plural expression unless the context clearly indicates otherwise. In addition, in explaining the present invention, if it is determined that a specific explanation of known technology related to the present invention may unnecessarily obscure the gist of the present invention, such detailed explanation shall be provided. omitted. The attached drawings are for easy understanding of the embodiments disclosed herein, and the technical ideas disclosed herein should not be limited by the attached drawings. .

FIG. 3 is a diagram showing the appearance of the clothing processing apparatus 10 according to the present invention.

A garment processing apparatus according to one embodiment of the present invention includes a cabinet 100 that forms an exterior appearance.

The cabinet 100 includes a front panel 110 that forms the front surface of the clothing processing apparatus, and the front panel 110 has an input port 111 that communicates with a drum 200 (described later) and a door 130 that is rotatably coupled to the cabinet and opens and closes the input port 111. Be prepared.

A control panel 117 is provided on the front panel 110. The control panel 117 includes an input section 118 into which control commands are input by the user, and a display section 119 through which information such as control commands selectable by the user is output. The control instructions include a drying course or drying option that performs a series of drying steps. Control panel 177 includes a main control that controls commands to perform drying courses or drying options.

The input unit 118 includes a power supply requesting unit for requesting power supply to the clothing processing device, a course inputting unit for allowing the user to select a desired course from among a large number of courses, and an execution unit for requesting the start of the course selected by the user. Includes request section.

The display unit 119 includes either a display panel capable of outputting text and graphics, and a speaker capable of outputting audio signals and sounds.

Meanwhile, the clothing processing apparatus according to the present invention includes a water storage unit 7 for separately storing water generated during the process of drying clothes. The water storage section 7 includes a water storage tank that can be drawn out from one side of the front panel 110. The water storage tank collects condensed water transferred from a cleaning pump, which will be described later. Thereby, the user can pull out the water storage tank from the cabinet 1, remove condensed water, and then reattach it to the cabinet 100. Therefore, the clothing processing apparatus according to the present invention can be used even in places where a sewer pipe or the like is not provided.

On the other hand, the water storage section 7 is arranged above the door 130. As a result, when the user pulls out the water tank from the front panel 110, the user bends relatively slightly at the waist.

Meanwhile, the clothing processing apparatus according to the present invention further includes a steam section 195 that supplies steam to the clothing (or inside the cabinet). The steam unit 195 generates steam using condensed water discharged from clothing, or generates steam by receiving fresh water other than condensed water. The steam section 195 generates steam by heating water, using ultrasonic waves, or vaporizing water.

The steam section 195 receives a certain amount of water and generates steam, so it occupies a certain volume. At this time, the front panel 110 of the cabinet is provided with a door and a control panel 117, and the back panel 120 of the cabinet is provided with a duct for supplying and discharging air to and from the drum, a water supply unit, and the like. Therefore, it is advantageous for the steam section 195 to be located inside the side panel 140 of the cabinet.

Further, the clothing processing apparatus according to the present invention includes a steam control section 800 for separately controlling the steam section 195. Although the steam control unit 800 is provided in the control panel 117, it may be provided as a separate control panel in order to prevent overloading of the control panel 117 and to prevent an increase in manufacturing costs.

Steam control section 800 is provided adjacent to steam section 195. The steam control unit 800 is installed on the side panel 140 where the steam unit 195 is installed, and the length of the control line connected to the steam unit 195 can be reduced.

Since the steam section 195 supplies steam that comes into contact with clothing, it is desirable to generate steam using fresh water. Since the water collected in the water reservoir 7 is generated from clothing, it may contain lint or foreign substances and is not suitable for steam generation.

Therefore, the clothing processing apparatus according to the present invention includes a water supply section 160 that supplies water to the steam section 195 and is provided separately from the water storage section 7 . The water supply unit 160 stores fresh water or receives fresh water from the outside and supplies it to the steam unit 195 .

For example, the water supply unit 160 includes an external supply unit 180 that receives water from an external water source and transmits it to the steam unit 195, and an internal supply unit 170 that separately stores fresh water and supplies it to the steam unit 195.

The internal supply unit 170 includes a water tank 171 that is provided separately from the water storage unit 7 and stores fresh water. The water tank 171 and the steam section 195 are installed at different heights so that the water in the water tank 171 is supplied to the steam section 195 by its own weight.

If a difference in installation height between the water tank 171 and the steam section 195 cannot be ensured, it is desirable to further provide a water pump 172. When the water pump 430 is arranged, the space inside the cabinet 1 can be utilized more compactly.

Accordingly, the water supply section 160 further includes a water pump 172 that supplies water from a water tank 171 to the steam section 195, and a tank housing 173 in which the water tank 171 and the water pump 172 are mounted in a cabinet.

The external supply unit 180 is connected to an external water supply source and includes a direct water valve to which water is supplied.

In addition, the clothing processing apparatus according to the present invention further includes a determining unit 196 that determines which of the external supply unit 180 and the internal supply unit 170 should be used preferentially to supply water to the steam unit 195.

The determining unit 196 determines which of the external supply unit 500 and the internal supply unit 400 should be used with priority.

Note that the water tank 171 stores fresh water. It is desirable that the water tank 171 be exposed outside the cabinet 100 so that it can be filled with fresh water at any time.

On the other hand, the water tank 171 may be provided in the cabinet 100 so that it can be pulled out. This allows the user to pull out the water tank 171 from the cabinet 100 and easily fill it with water.

Water tank 171 is pulled out through front panel 110. However, when the water tank is also pulled out through the front panel 110, it is difficult to secure an area in which the water tank 171 can be pulled out due to the area occupied by the control panel 117 on the front panel 110.

Therefore, the water tank 171 can be pulled out through the upper panel 130 to prevent interference with the control panel 117.

On the other hand, since the water tank 171 also stores water and the water storage section 7 also stores water, there is a possibility of confusion among users. Therefore, in the clothing processing apparatus according to the present invention, the directions and positions in which the water tank 171 and the water storage section 7 are exposed from the cabinet may be different.

That is, the water tank 171 is exposed to the upper panel 130 and the water storage part 7 is exposed to the front panel 11. Thereby, even if both the water tank 171 and the water storage section 7 are provided, it is possible to prevent the user from confusing the water tank 171 and the water storage section 7. In addition, the water tank 171 must store fresh water and maintain the freshness of the stored water, so its volume is relatively smaller than that of the water storage section 7. Therefore, the user can also distinguish between the water tank 171 and the water storage section 7 based on the volume difference.

Since the water tank 171 has a smaller volume than the water storage section 7, it can be easily drawn out from the top. Therefore, the water tank 171 can be provided so as to be drawn upward from the upper panel 130. As a result, since the drawing directions of the water tank 171 and the water storage section 7 are different from each other, the possibility of user confusion is further reduced.

The upper panel 130 of the clothing processing apparatus according to the present invention includes a tank draw-out hole or draw-out hole 131 for exposing the water tank 171 to the outside or pulling out the tank 171 to the outside of the cabinet. The tank extraction hole 131 has a cross-sectional area corresponding to or slightly larger than the cross-sectional area of the water tank 171 .

The upper panel 130 further includes a drawer cover 132 that covers the tank drawer hole 131 and prevents the water tank 171 from being pulled out arbitrarily.

The clothing processing device according to the present invention further includes a filter for removing foreign substances from the circulating flow path. The front panel 110 is provided with a filter attachment hole 113 through which a filter is pulled out or inserted.

FIG. 4 is a diagram showing the inside of the clothing processing apparatus according to the present invention.

The clothing processing apparatus according to the present invention includes a drum 200 that is housed in a cabinet 100 and stores clothes, a driving part (M) that rotates the drum 200, and a hot air supply part 900 that supplies hot air to the drum 200.

Drum 200 is cylindrical and stores clothing. Further, since there is no need for water to be introduced into the drum 200 and no need for water condensed within the drum 200 to be discharged to the outside, the through holes provided along the circumference of the drum 200 can be omitted.

The drive unit (M) is directly connected to the drum 200 to rotate the drum 200. For example, the drive unit (M) is a DD (Direct Drive unit) type. As a result, the driving unit (M) directly rotates the drum 200 without using a belt, a pulley, or the like, and thereby can control the rotational direction of the drum 200 or the rotational speed of the drum 200.

Generally, in the case of a DD type washing machine, a driving part (M) is coupled to and fixed to a tub housing a drum 200, and the drum 200 is coupled to the driving part (M) and supported by the tub. However, since the clothes processing apparatus according to the present invention concentrates on the drying process, the tub fixed to the cabinet 100 for accommodating the drum 200 is omitted.

Accordingly, the garment processing apparatus according to the present invention further includes a support part 400 for fixing or supporting the drum 200 or the driving part (M) in the cabinet 100.

The support section 400 includes a front case 410 provided in front of the drum 200 and a rear case 420 provided in the rear of the drum 200. The front case 410 and the rear case 420 are plate-shaped, and are provided so that the front and rear sides of the drum 200 face each other. The distance between the front case 410 and the rear case 420 is set to be the same as the length of the drum 200 or longer than the length of the drum 200. The front case 410 and the rear case 420 are fixed and supported by the bottom surface of the cabinet 100 or a hot air supply section 900, which will be described later.

Since the input port for the drum 200 is provided at the front, it is preferable that the drive unit (M) be provided in the rear case 420 rather than the front case. The rear case 420 is formed so that a driving part (M) is attached and supported in an area facing the back surface of the drum 200. Thereby, the drive unit (M) can rotate the drum 200 in a state where the position is stably fixed via the rear case 420.

Both the front case 410 and the rear case 420 rotatably support the drum 200. Either the front case 410 or the rear case 420 rotatably accommodates the front end or the rear end of the drum 200.

For example, the front of the drum 200 is accommodated in a front case 410 and supported rotatably, and the rear of the drum 200 is spaced apart from a rear case 420 and is connected to a drive unit (M) attached to the rear case 420, thereby indirectly supporting the rear case 420. Supported by This minimizes the area where the drum 200 contacts or rubs against the support portion 400, making it possible to block unnecessary noise and vibration.

Of course, the drum 200 may be rotatably supported by both the front case 410 and the rear case 420.

The hot air supply unit 900 forms a circulation flow path for discharging the air inside the drum 200 to the outside and introducing it into the drum 200, and heats the circulating air and condenses moisture in the circulating air to supply the air to the drum 200. Dry stored clothes.

It is preferable that the hot air supply unit 900 is disposed at a lower part of the drum 200 so that the input port of the drum 200 is located at a relatively high position and the user can easily pull out the clothes in the drum 200.

The hot air supply unit 900 includes a plurality of heat exchangers that cool or heat the air flowing therein, and also includes a cleaning unit 940 that removes foreign substances attached to the heat exchangers using condensed water in the air.

The hot air supply section 900 supplies air into the drum 200 via the front case 410 and discharges the air toward the rear case 420.

A duct cover 430 that guides the hot air supplied from the hot air supply unit 900 to the rear surface of the drum 200 is coupled to the rear case 420 . The duct cover 430 exposes the driving part (M) to the outside and cools the driving part (M). The cabinet 100 further includes a shielding plate 120 that prevents the duct cover 430 and the driving part (M) from being exposed to the outside, thereby preventing safety accidents.

The longitudinal length (T1) of the cabinet is the length from the front case 410 to the rear panel 120. Strictly speaking, the length of the cabinet is from the front panel 120 to the back panel 120, but since the length from the front case 410 to the back panel 120 corresponds to the allowable space in which the internal structure of the clothing processing device according to the present invention is provided, The length of the space (T1 = allowable length) is simply referred to as the length of the cabinet.

Once the allowable length (T1) is determined, the length (T2) of the drum 200 and the length (T3) of the driving section are determined. The allowable length (T1) includes the drum length (T2) and the length of the drive section (T3), and is equal to or smaller than the sum of the drum length (T2) and the length of the drive section (T3).

On the other hand, if the back panel 120 is omitted, the rear case 420 may form the back surface of the cabinet.

FIG. 5 is a diagram showing a drum of the clothing processing apparatus according to the present invention.

The drum 200 of the clothing processing apparatus according to the present invention is not indirectly rotated by being connected to a belt or the like, but is directly connected to a driving part (M) and rotated. Therefore, unlike the drum of a conventional dryer, which has a cylindrical shape with open front and rear sides, the drum 200 of the clothing processing apparatus according to the present invention is shielded at the rear and directly connected to the drive unit (M). Ru.

Specifically, the drum 200 includes a cylindrical drum body 210 that accommodates clothing, and a drum back 220 that is coupled to the rear of the drum body 210 to form a back surface of the drum.

The drum rear surface 220 shields the rear of the drum body 210 and provides a space directly connected to the driving part (M). That is, the drum rear surface 220 is connected to a driving part (M) and is directly supplied with power to rotate the drum body 210. As a result, an input port 211 into which clothing is input is formed at the front of the drum body 210, and the rear side is shielded by the drum back surface 220.

A bushing part 300 coupled to a driving part (M) is coupled to the drum rear surface 220. The bushing part 300 is provided on the back surface 220 of the drum and forms the center of rotation of the drum 200. Although the bushing part 300 may be formed integrally with the drum back surface 220, it is made of a material that is more rigid and durable than the drum back surface 220 in order to be firmly coupled to the rotating shaft extending from the drive part (M). The bushing part 300 is coupled to the middle of the drum rear surface 220.

The drum back surface 220 includes a circumferential portion 221 coupled to the outer circumferential surface of the drum body 210, and a seat portion 223 provided inside the circumferential portion 221 and coupled to the driving portion (M). The seat part 223 may be coupled with the bushing part 300 and may include a through hole through which the bushing part 300 is received.

A suction hole 224 is provided between the circumferential portion 221 and the seat portion 223 to guide hot air supplied from the hot air supply unit 900 into the drum body 210 . The suction hole 224 may be formed of a plurality of holes provided through the drum back surface 220, or may be formed of a mesh-like net.

In order to prevent the rigidity of the drum rear surface 220 from being reduced by the suction holes 224, a reinforcing rib 225 is further provided to reinforce the rigidity of the drum rear surface 220. The reinforcing ribs 225 extend radially from the outer circumferential surface of the seat portion 223 toward the inner circumferential surface of the circumferential portion 221 . Further, a circumferential rib 226 is further provided extending around the drum back surface 220 so as to connect the reinforcing ribs 225 to each other. Suction holes 224 are arranged between the reinforcing ribs 225, the circumferential ribs 226, the seat portion 223, and the circumferential portion 221. It is possible to maintain the shape even if it is transmitted.

Meanwhile, one or more reinforcing beads 212 are provided on the outer peripheral surface of the drum body 210 to reinforce the rigidity of the drum body 210. The reinforcing beads 212 may be recessed or protruded inwardly or outwardly along the circumference of the drum body 210, and a plurality of reinforcing beads 212 may be spaced apart along the length of the drum body 210.

As a result, even if a large amount of clothing is stored in the drum body 210 or a rotational force is suddenly transmitted through the drive unit (M), the drum body 210 can be prevented from being twisted.

As a result, the drum 200 of the clothing processing apparatus according to the present invention is not rotated by a belt or the like, but is rotated by having the drum rear surface 220 directly connected to the driving part (M).

Therefore, even if the driving unit (M) changes its rotational direction or its rotational speed is high, the drum 200 of the clothing processing apparatus according to the present invention can immediately reflect the change and rotate.

FIG. 6 is a diagram showing the internal configuration of the clothing processing device according to the present invention.

As described above, the drum 200 has a cylindrical shape and includes a drum body 210 that is open at the front and the rear, and a drum rear surface 220 that is coupled to the rear of the drum body 210 to shield the rear of the drum body 210.

A rotating shaft extending from the driving part (M) is directly coupled to the bushing part 300.

The front case 410 includes a front plate 411 forming a main body, and an input communication hole 412 that passes through the front plate 411 and accommodates the front side of the drum body 210 or the input port 211.

The gasket 413 rotatably supports the input port 211 of the drum body 210 and can come into contact with the outer peripheral surface of the input port 211. The gasket 413 prevents hot air inside the drum 200 from leaking between the drum body 210 and the front plate 411. The gasket 413 is made of a plastic resin or an elastic material, and another sealing member is further coupled to the inner peripheral surface of the gasket 413 to prevent clothes or hot air from leaving the input port 211 of the drum body 210 to the front plate 411. be able to.

On the other hand, a duct communication hole 419 is formed on the inner circumferential surface of the gasket 413 or the input communication hole 412, which communicates with the drum body 210 and allows the air introduced into the drum body 210 to be discharged. A flow path connecting the duct communication hole 419 and the hot air supply section 900 is provided inside the front plate 411 . Thereby, the duct communication hole 419 guides the air discharged from the drum body 210 to be supplied to the hot air supply section 900.

A filter member is provided in the duct communication hole 419 to block foreign substances and lint discharged from the drum 200 from being introduced into the hot air supply section 900 .

The front case 410 includes a front wheel 415 that is provided so as to be able to come into contact with the outer peripheral surface of the drum body 210 and rotatably supports the drum 200. The front wheels 415 support the outer peripheral surface of the input port of the drum body 210, and a plurality of front wheels 415 are provided at intervals along the outer peripheral surface of the input communication hole 412. The front wheel 415 supports the lower portion of the drum body 210 and rotates when the drum 200 rotates.

Further, a stopper 500 is coupled to the front case 410 to prevent the drum body 210 from detaching. The stopper 500 may be disposed in a stopper installation part 416 disposed in the front case 410 above the input communication hole 412.

The front case 410 is provided with a tank support hole 414 through which the water tank of the water tank 7 is pulled out or supported. Tank support hole 414 is provided in a region of front panel 110 corresponding to a portion where water tank 7 is arranged, and is formed to penetrate front case 410 .

A cutout 417 supported by the hot air supply unit 900 is provided at the bottom of the front case 410 . The cutout portion 417 can prevent the front case 410 from interfering with the hot air supply section 900. The cutout section 417 communicates with the supply duct of the hot air supply section 900 and transmits the air in the drum supplied to the duct communication hole 419 to the hot air supply section 900 .

The hot air supply unit 900 includes a circulation passage 920 through which air discharged from the drum 200 circulates. The circulation flow path 920 is arranged outside the drum 200 and has a duct shape. The circulation flow path 920 has a supply duct 921 that communicates with the duct communication hole 419 to which the air of the drum 200 is supplied, a moving duct 922 through which the air supplied from the supply duct 921 moves, and a moving duct 922 through which the air that has passed through the moving duct 922 moves. and a discharge duct 923 for discharge.

The supply duct 921 communicates with the cutout 417 of the front case 410 and with a flow path provided within the front case 410 . The moving duct 922 extends from the end of the supply duct 921 toward the rear of the drum 200 , and the discharge duct 923 is provided at the end of the moving duct 922 to guide air to the drum 200 .

Meanwhile, a heat pump 950 that cools or heats air is installed inside the hot air supply unit 900. The heat pump 950 includes an evaporator 951 that is installed in the moving duct 922, cools the air and condenses moisture contained in the air, and is spaced downstream from the evaporator 951 or toward the exhaust duct 923, and reheats the air. and a condenser 952. The heat pump 950 further includes an expansion valve that cools the refrigerant that has passed through the condenser 952 and guides it to the evaporator 951 again, and a compressor 953 that pressurizes and heats the refrigerant that has passed through the evaporator 951 and supplies it to the condenser 952. including. Compressor 953 is placed outside moving duct 922 .

The evaporator 951 and the condenser 952 are comprised of heat exchangers through which refrigerant flows.

The hot air supply unit 900 further includes a connector 930 that communicates with the discharge duct 923 and guides the hot air to the rear of the drum 200 or to the duct cover 430. The connector 930 is provided above the exhaust duct 923 and guides the hot air that has passed through the condenser 952 and is heated to the rear of the exhaust duct 923 .

Meanwhile, the hot air supply unit 900 further includes a blower fan 9531 that moves air within the drum 200 to the supply duct 921 or inputs air that has passed through the exhaust duct 923 into the drum 200. The blower fan 9531 is provided within the exhaust duct 923 and is controlled together with the drive unit (M) by the main control unit.

Rear case 420 includes a rear plate 421 that faces front plate 411 . The rear case 420 includes a mounting part 429 on which the driving part (M) is coupled and mounted. The mounting portion 429 passes through the rear case 420, and the driving portion (M) is attached to the mounting portion 429 and fixed within the cabinet 100. The mounting part 429 supports the load of the driving part (M), and the driving part (M) is provided at a position corresponding to the drum back surface 220.

The rear plate 421 is further formed with an air movement hole 423 that communicates with the connector 930 and allows air to flow in, and a communication hole 424 that allows the air that has passed through the air movement hole 423 to be discharged to the drum rear surface 220.

A duct cover 430 is coupled to the rear surface of the rear plate 421 to form a flow path through which air flowing in through the connector 930 is transferred to the suction hole 224 provided on the drum rear surface 220 .

The duct cover 430 is coupled to the rear plate 421 and is spaced apart from the suction hole 224 to form a space between the rear plate 421 and the duct cover 430 in which air moves.

The duct cover 430 covers the communication holes 424 so that all the communication holes 424 are not exposed to the outside. Thereby, all of the air that has flowed into the duct cover 430 is discharged into the communication hole 424, and can be prevented from leaking to the outside. The duct cover 430 accommodates the drive unit (M) at a distance from the outer peripheral surface of the drive unit (M) to prevent interference with the drive unit (M), and to guide cooling of the drive unit (M). The drive part (M) is exposed to the outside.

On the other hand, since the duct cover 430 is heated by hot air and the drive unit (M) also includes a rotating rotor, the rear panel 120 is disposed behind the duct cover 430 to shield it. The rear panel 120 is coupled to the rear case 420 to prevent the duct cover 430 and the driving part (M) from being exposed to the outside. It is disposed apart from the duct cover 430 and the driving part (M).

The driving unit (M) includes a motor unit 600 that provides power to rotate the drum 200. The motor unit 600 includes a stator 610 that generates a rotating magnetic field and a rotor 620 that is rotated by the stator 610.

The rotor 620 is an outer rotor type that houses the stator 610 and rotates around the stator 610. At this time, a rotating shaft may be coupled to the rotor 620 and directly connected to the drum 200 through the stator 610 and the attachment part 429. In this case, the rotor 620 directly transmits power to rotate the drum 200.

Meanwhile, rotor 620 is rotated by stator 610 at high RPM. For example, the clothing in the drum 200 may be rotated at a higher RPM than the RPM at which the clothing can be rotated while remaining attached to the inner wall of the drum 200.

However, if the clothes in the drum 200 continue to rotate while attached to the inner wall of the drum 200, the portions attached to the inner wall of the drum are not exposed to hot air, resulting in a decrease in drying efficiency.

If the rotor 620 rotates at a low RPM so that the clothes do not adhere to the inner wall of the drum 200 and are rolled or agitated within the drum 200, a problem arises in which the output and torque generated by the drive unit (M) cannot be properly utilized. do.

Therefore, the drive unit (M) of the garment processing apparatus according to the present invention further includes a speed reducer 700 that increases torque while reducing the RPM and utilizing the maximum output of the motor unit 600.

A speed reducer 700 connects the motor section 600 and the drum 200. The speed reducer 700 converts the power of the motor section 600 to rotate the drum 200. The speed reducer 700 is disposed between the motor unit 600 and the drum 200, receives power from the motor unit 600, converts it, and transmits it to the drum 200. Reducer 700 converts the rotor RPM to a lower RPM, but increases the torque value and transmits it to drum 200.

Specifically, the reducer 700 is coupled to a drive shaft 630 that extends from the rotor part 610 and rotates together with the rotor part 610. The reducer 700 includes a gearbox that meshes with the drive shaft 630 and rotates to change the rpm of the drive shaft 630 and increase torque, and the gearbox is a rotating shaft that is coupled to the drum 200 and rotates the drum. 740. Thus, as drive shaft 630 rotates, rotation shaft 740 rotates at a lower RPM than drive shaft 630, but can rotate with greater torque.

The performance of the speed reducer 700 changes depending on whether the drive shaft 630 and the rotating shaft 740 are coaxial. That is, if the drive shaft 630 and the rotation shaft 740 are shifted from each other, there is a risk that the connection between the parts that constitute the gearbox in the reducer 700 and either the drive shaft 630 or the rotation shaft 740 may be loosened or the connection may be released. . Therefore, the power of the drive shaft 630 may not be properly transmitted to the rotation shaft 740, or the drive shaft 630 may idle.

Furthermore, even if the drive shaft 630 and the rotating shaft 740 are temporarily misaligned, the gearbox within the reducer 700 will be misaligned and collide with each other, causing unnecessary vibrations and noise.

Furthermore, if the angle at which the drive shaft 630 and the rotating shaft 740 are temporarily shifted becomes large, there is a risk that the gearbox within the reduction gear 700 may be completely disengaged from its normal position or may be damaged.

As a result, if the drive shaft 630 and the rotating shaft 740 cannot maintain coaxiality or are not arranged in parallel even temporarily, the performance of the reducer 700 cannot be guaranteed and the drum 200 cannot rotate as intended.

Therefore, normally, in a clothing processing apparatus equipped with a speed reducer, the speed reducer and the motor are fixed to a support that maintains its original state without deformation even if an external force is generated.

For example, in the case of a washing machine, the tub that houses the drum is firstly fixed to the cabinet, and then the motor and speed reducer are secondarily fixed to a rigid bearing housing that is injection molded inside the tub. apply. In addition, a fixed steel plate connected to the tab is placed outside the tab, and the motor and reducer are fixed to the fixed steel plate.

As a result, even if considerable vibration occurs in the tab, the reducer and the drive unit tilt or vibrate together with the bearing housing and the fixed steel plate. As a result, the speed reducer and the drive unit themselves can always maintain a connected state, and the coaxial state of the drive shaft and the rotating shaft can be maintained.

However, since the clothes processing apparatus according to the present invention is a dryer, the structure of the tab fixed in the cabinet is omitted. Further, since the back panel 120 of the cabinet is made of a relatively thin plate, even if the stator 610 is fixed, the back panel 120 easily vibrates or bends due to repulsive force when the rotor 620 or the drive shaft 630 rotates. When the back panel 120 vibrates or temporarily bends, the rotating shaft 740 and the driving shaft 630, which are arranged in combination with the drum 200, bend, causing a problem that the rotating shaft 740 and the driving shaft 630 become misaligned.

Furthermore, since the rear panel 120 is made of a thin steel plate, it cannot support the entire reduction gear 700 and motor section 600. For example, when the reducer 700 and the motor section 600 are connected to the rear panel 120 in parallel, a rotational moment is generated due to the overall length and weight of the reducer 700 and the motor section 600, causing the problem that the reducer 700 hangs downward. do. As a result, the rotating shaft 740 itself coupled to the drum becomes misaligned with the reducer 700 and cannot maintain coaxiality with the drive shaft 630.

Furthermore, the back panel 120 cannot support the motor unit 600 itself. One side of the rear panel 120, on which the motor part 600 is provided, may bend downward due to the weight of the motor part 600. The rear panel 120 is not originally configured to be suitable for coupling the motor unit 600 itself.

On the other hand, it is conceivable that the stator 620 is coupled to the rear case 420 and the motor section 600 is supported. When a large amount of clothing is stored in the drum 200 or eccentricity occurs, the rotation axis 740 may shift along the clothing placement each time the drum 200 rotates. At this time, since the stator 610 is separated from the drum 200 and fixed to the rear case 420, the rotating shaft 740 vibrates with a different width or tilts at a different angle than the stator 610. Therefore, the rotating shaft 740 and the driving shaft 630 cannot remain coaxial.

Further, the drum 200 is supported by a front case 410 and a rear case 420, or its installed position is fixed at a certain level by a stopper 500, which will be described later. Therefore, the position of the rotating shaft 740 coupled to the drum 200 is also fixed at a certain level. Therefore, even if vibration occurs in the drum 200, the vibration is damped by either the front case 410 or the rear case 420 or the stopper 500.

However, if the vibration generated in the drum 200 is transmitted to the motor section 600, even if the reducer 700 and the motor section 600 are fixed to the rear case 420, the motor section 600 and the rear case 420 will be larger than the vibration width of the rotating shaft 740. The vibration width is larger. At this time as well, there is a possibility that the drive shaft 630 and the rotating shaft 740 cannot remain coaxial.

To solve this problem, in the clothing processing apparatus according to the present invention, the motor unit 600 is coupled and fixed to the speed reducer 700. In other words, the reducer 700 itself serves as a reference point for the entire drive section (M). That is, the reducer 700 serves as a reference for the vibration and tilt angle of the entire drive unit (M).

Since the motor unit 600 is not fixed to other components of the clothing processing device, but is fixed only to the reducer 700, the reducer 700 tilts when vibrations or external force are transmitted to the drive unit (M). When the motor part 600 tilts or vibrates at the same time as the reducer 700, the motor part 600 always tilts or vibrates at the same time as the reducer 700.

As a result, the reducer 700 and the drive unit 600 form one vibration system, and the reducer 700 and the drive unit 600 do not move relative to each other and can maintain a fixed state.

A stator 610 of the drive unit 600 is directly coupled and fixed to the reducer 700. As a result, the position where the drive shaft 630 is provided with respect to the reduction gear 700 does not change. The center of the drive shaft 630 and the center of the reducer 700 are aligned with each other, and the drive shaft 630 rotates while being coaxial with the center of the reducer 700.

The above-mentioned meanings of coaxiality and coincidence do not mean physically perfect coaxiality and coincidence, but allow for an error range that is acceptable in mechanical engineering or a level range that a person skilled in the art would recognize as coaxiality or coincidence. This is the concept of For example, a range in which the drive shaft 630 and the rotation shaft 740 are deviated within 5 degrees can be defined as being coaxial or coincident.

Although the drive shaft 630 rotates with respect to the reducer 700, it is fixed to prevent it from tilting, and the stator 610 is also fixed to the reducer 700, so the distance between the stator 610 and the rotor 620 is always maintained. Ru. As a result, collision between the stator 610 and the rotor 620 is prevented, and noise and vibration generated by the rotation center of the rotor 620 changing while rotating the stator 610 can be basically blocked.

The rotating shaft 740 extends toward the drum 200 within the reducer 700, vibrates together with the reducer 700, and tilts together with the reducer 700. That is, the rotating shaft 740 is only provided to be rotated by the reducer 700, and the provided position is fixed. As a result, the rotating shaft 740 and the driving shaft 630 are always arranged parallel to each other and form the same axis. In other words, the center of the rotation shaft 740 and the center of the drive shaft 630 are maintained in the same state.

The speed reducer 700 and the motor unit 600 are arranged along the first axis (S1) parallel to the ground when there is no load on the drum 200 or when the motor unit 600 does not operate. The driving shaft 630 and the rotating shaft 740 are also arranged in parallel along the first axis (S1).

However, when vibrations occur in the drum 200 or in the motor section 600, the vibrations are transmitted to the reducer 700 and the reducer 700 vibrates or tilts, causing the reducer 700 to temporarily shift to the It will be in a state where it is tilted towards the second axis (S2).

At this time, since the motor unit 600 is coupled to the reducer 700, it vibrates together with the reducer 700 or is tilted and disposed parallel to the second axis (S2). Therefore, the drive shaft 630 and the rotation shaft 740 are also arranged parallel to each other along the second axis (S2).

As a result, even if the reducer 700 is tilted, the motor unit 600 moves together with the reducer 700, and the drive shaft 630 and the rotating shaft 740 remain coaxial.

Therefore, since the drive shaft 630 and the rotating shaft 740 are always tilted with respect to the reducer 700, the reducer 700 serves as the action point (P1) of the lever or seesaw. That is, the speed reducer 700 serves as a first point of action (P1) of the vibration system including the motor section 600. On the other hand, the reducer 700 is coupled to the drum 200 via the rotation shaft 740, and since the drum 200 is separated from the rear case 420, the load of the drum 200 is transmitted to the reducer 700. The system including not only the motor part 600 but also the drum 200 forms one vibration system, and the reduction gear 700 can serve as a reference or point of action (P1) of the vibration system.

Even though the reducer 700 itself serves as the center or point of action (P1) of the vibration system, it must be fixed or supported within the cabinet 100.

For this purpose, the reducer 700 is coupled and fixed to the rear case 420. In this case, since the reducer 700 tilts or vibrates while being coupled to the rear case 420, the rear case 420 can play a central role in the vibration system including the reducer 700, the motor unit 600, and the drum 200. Even in this case, the motor section 600 is not directly coupled to the rear case 420 even though it can come into contact with the rear case 420, but is coupled and fixed only to the speed reducer 700.

Specifically, the attachment part 429 of the rear case 420 serves as the second point of action (P2) of the lever or seesaw formed by the reducer 700, the motor part 600, and the drum 200.

After the reducer 700, the motor unit 600, and the drum 200 are arranged in parallel along the first axis (S1), the reducer 700 becomes parallel to the third axis (S3). The third shaft (S3) passes through a reduction gear 700 coupled to the rear case 420. At this time, since the speed reducer 700 and the motor section 600 are coupled, the motor section 600 is also parallel to the third axis (S3).

Finally, the driving unit 600 and the drum 200 are coupled to the reducer 700, so that the driving unit 600 and the drum 200 tilt parallel to each other or vibrate simultaneously with the reducer 700 as a reference.

In the clothing processing apparatus according to the present invention, the drum 200 is not connected to a belt, but is supported by a speed reducer 700. Therefore, when the drum 200 is rotated by the speed reducer 700, it is lifted upward or tilted downward by centrifugal force or the like.

To prevent this, the garment processing apparatus according to the present invention further includes a stopper 500 for fixing the position of the drum 200. The stopper 500 includes a front stopper 510 located in front of the drum 200 and a rear stopper 520 located at the rear of the drum.

At this time, the drum 200 is lifted upward with respect to the rotating shaft 740. Therefore, the front stopper 510 is arranged so as to contact the upper part of the front side of the drum.

Further, the drum 200 may sag at the bottom due to the weight of the clothes. Therefore, the rear stopper 520 is arranged so as to be in contact with the rear lower part of the drum 200.

The front stopper 510 is coupled to the installation part 416 of the front case 410, and the rear stopper 520 is supported on the upper part of the heat exchange part 900.

FIG. 7 is a diagram showing a stopper 500 that supports the drum 200 of the garment processing apparatus according to the present invention.

The drum 200 is coupled to the free end of the rotating shaft 740 for rotation. The rotating shaft 740 is fixed to the reducer 700 to prevent it from shifting from the reducer 700.

However, the drum 200 may shift upward or downward due to the load of clothing or falling of clothing during rotation. As a result, the drum 200 may shift upward or downward with respect to the free end of the rotating shaft 740.

In particular, the drum 200 vibrates or tilts independently with respect to the free end of the rotation axis 740. That is, the drum 200 is made of a material that has elasticity and is made of a material that can be deformed to a certain level. This prevents transient vibrations and external forces from being transmitted to the rotating shaft 740, thereby preventing misalignment of the rotating shaft 740 and the drive shaft 630.

Further, since the drum 200 is not fixed by a belt or the like, transient vibration energy is generated when the drum 200 rotates with clothes stored therein.

On the other hand, a front case 410 and a rear case 420 are arranged in front and behind the drum 200. The front case 410 can be prevented from coming into direct contact with the front of the drum 200 via the input communication hole 412 and the gasket 413. However, since the back surface of the drum 200 is directly connected to the rotating shaft 740, the rear surface of the drum body 210 is shielded by the drum back surface 220, and the rear case 420 has a drive unit (M) in a portion directly facing the drum back surface 220. A mounting portion 429 for fixing must be provided. That is, unlike the front case 410, the rear case 420 cannot have a through hole on one side facing the drum.

Therefore, if the rear case 420 rotatably supports the rear or rear surface of the drum 200 like the front case 410, there is a risk that the drum rear surface 220 and the rear case 420 will directly rub and collide.

Specifically, the rear case 420 has many parts that interfere with the drum back surface 220, such as a drum housing groove 422, an air movement hole 423, and a mounting portion 429, which will be described later. If the rear case 420 directly supports the drum 200 in such a situation, the drum back surface 220 and the rear case 420 may be worn out or damaged.

Therefore, the rear case 420 must be maintained a certain distance apart from the drum 200, and the rear case 420 itself cannot directly support the drum 200.

Further, when the drum 200 rotates with a large amount of clothing stored therein, there is a possibility that the drum 200 rotates while moving toward the front case 410 or the rear case 420 because there is no belt or the like.

Taking these into consideration, the garment processing apparatus of the present invention further includes a stopper 500 that limits the movement of the drum 200 within an acceptable range.

The stopper 500 includes a front stopper 510 that is coupled to the front case 410 to support the front upper end of the drum, a support wheel 533 that is rotatably provided to the front case 410 and supports the front lower end of the drum, and a rear case 420 that is coupled to the front stopper 510 that supports the front upper end of the drum. and includes a rear stopper 520 that supports the rear lower end of the drum.

The drum 200 is rotated while being supported by a driving part (M) and a support wheel 533, and a front stopper 510 and a rear stopper 520 are provided to restrict transient movement of the drum 200. Thereby, the front stopper 510 and the rear stopper 520 can reduce vibrations of the drum 200 and temporarily generated shocks, and can prevent the front stopper 510 and the rear stopper 520 from damaging the drum 200 on the contrary.

Referring to FIG. 7(a), the front stopper 510 includes a fixing plate 5111 coupled to the stopper installation part 416 of the front case 410, a lever plate 5112 extending rearward from the fixing plate 5111, and an extension extending downward from the lever plate 5112. It includes a plate 5113, a support plate 512 provided at the front upper end of the drum 200 in the support plate 5113, and a felt 513 coupled to the lower part of the support plate 512 and in contact with the drum 200.

As a result, when the drum 200 is lifted upward, the front stopper 510 absorbs the impact of the drum 200 while the lever plate 5112 and the extension plate 5113 are lifted upward to a certain level, and the felt 513 rubs against the front of the drum 200. The drum 200 is restricted from being lifted upward excessively.

The outer peripheral surface of the input port 211 of the drum 200 includes a grounding portion 213 that extends to a diameter smaller than that of the drum body 210 and is in contact with the support wheel 533 and the felt 513 . As a result, the felt 513 and the support wheel 533 are accurately placed on the ground contact portion 213, and the movement of the drum 200 can be restricted.

The front stopper 510 is spaced apart from the front upper end of the drum by a specific distance. The specific interval corresponds to an interval that allows the drum 200 to come off the gasket 413 during rotation, or corresponds to a range that allows the drum 200 to twist the rotating shaft 740 transiently.

Referring to FIG. 7(b), the front stopper 510 includes a support plate 512 and a contact wheel 532 in which a felt 513 rotatably contacts the ground contact portion 213.

Thereby, the support wheel 533 supports the lower part of the grounding part 213, and the contact wheel supports the upper part of the grounding part 213, so that the drum 200 can be prevented from coming off from the input communication hole 412.

Referring to FIG. 7(c), when the rear case 420 and the drum 200 are separated, the rear stopper 520 and the drive unit (M) support the rear of the drum 200, and the drum 200 approaches the rear case 420 transiently, the rear Stopper 520 prevents this. As a result, damage caused by friction or contact between rear case 420 and drum 200 can be prevented.

The rear stopper 520 is disposed in front of the rear case 420 to prevent the drum rear surface 220 from contacting or colliding with the rear case 420. When clothes are stored in the drum 200 and rotates, since the drum 200 is not fixed by a belt, an external force is generated that causes the drum 200 to move not only upward or downward but also forward or backward.

Since the rear case 420 supports the load of the drive unit (M), it needs to be made of a material that is thicker or has greater rigidity than the front case 410. Therefore, when the drum 200 moves downward, the rear case 420 supports the movement of the drum 200 without buffering it, which may generate a repulsive force that pushes the drum 200 upward.

During this process, the drum 200 is strongly pressurized toward the front case 410, and in severe cases, the door 130 will be forced open.

Therefore, the rear stopper 520 is spaced apart from the rear of the drum 200 by a standard distance, allowing the drum 200 to move rearward to a certain level. This can prevent the drum 200 from excessively pressurizing the front case 410.

The reference interval is an interval at which the back surface of the drum 200 and the rear stopper 520 can contact and support when the drum 200 accommodates more than the standard amount of clothes and the drum 200 is pushed backward during rotation.

Accordingly, the rear stopper 520 supports the drum 200 only when the drum 200 moves backward by the reference distance, thereby preventing the rear stopper 520 from being worn out. A felt that contacts the drum 200 is attached to the rear stopper 520.

Further, the drum 200 and the rear case 420 are spaced apart from each other by a reference distance or more.

The rear stopper 520 includes a support coupling part 521 supported by the bottom surface of the cabinet 100 or the hot air supply part 900, a support leg part 522 extending from the support coupling part 521 toward the drum 200, and a support leg part 522 extending diagonally forward from the support leg 522. It includes an extension part 524 and a restriction part 525 extending from the extension part 524 to face the drum back surface 220.

The support legs 522 are further provided with cut grooves 523 therein to enhance rigidity.

The extension part 524 extends diagonally from the support leg part 522, buffers the external force applied from the drum 200 to a certain level, and strengthens the overall rigidity of the rear stopper 520.

Extension portion 524 includes an inclined extension portion 5241 extending forwardly from support leg portion 522 and a linear extension portion 5242 extending upwardly from inclined extension portion 5241.

The restriction portion 525 includes a separation portion 5251 that extends rearward from the linear extension portion 5242 and is spaced apart from the drum back surface 220, and a load support portion 5252 that is provided to face the lower portion of the drum back surface 220 at the separation portion 5251. .

In order to reinforce the rigidity of the load support part 5252, a curved part 5253 provided by bending the free end of the load support part 5252 is further provided.

The rear stopper 520 can be prevented from directly contacting the rear of the drum 200 by the separating part 5251. On the contrary, the drum 200 is allowed to move rearward at a certain level.

As a result, the rear case 420 is disposed between the rear stopper 520 and the speed reducer 700 or the drive unit 600.

Meanwhile, the rear stopper 520 is spaced apart from the bottom of the drum by a certain distance. The constant interval corresponds to an interval at which the drum 200 deviates from the sealing part 490 or an interval at which the rotating shaft 740 is transiently distorted.

That is, the linear extension 5242 is spaced apart from the rear of the drum 200 by a predetermined distance.

FIG. 8 is a diagram showing the structure of a rear case 420 according to the present invention.

The motor section 600 is coupled and fixed to the reducer 700, and even if the reducer 700 itself serves as a reference for the position and vibration of the drive section (M), the reducer 700 is connected to the back surface of the drum 200 in order to rotate the drum 200. It must be supported while being placed in the

Therefore, the reducer 700 is mounted on the rear case 420 and supported within the cabinet 100. However, the motor unit 600 and the drum 200 are spaced apart from the rear case 420. This can prevent the motor section 600 or the drum 200 from being interfered with by components other than the reducer 700 and moving separately from the reducer 700.

As a result, the rear case 420 serves as a see-saw action point in the vibration system or rotation system including the reducer 700, the motor unit 600, and the drum 200.

The rear case 420 includes a rear plate 421 disposed on the back surface of the drum 200 and facing the front plate 411, and a drum accommodating groove 422 protruding from the rear plate 421 to face the drum back surface 220. The drum housing groove 422 is formed to protrude from the rear plate 421 and has a diameter and depth that partially accommodates the outer peripheral surface of the drum rear surface 220 and is spaced apart from the drum rear surface 220 . That is, the drum housing groove 422 protrudes from the rear plate 421 by a first height (L1) so that the drum rear surface 220 is partially housed in front of the rear plate 421. The drum housing groove 422 is provided with a plurality of communication holes 424 that face the suction holes 224 of the drum back surface 220 and through which air passes. A reinforcing bent portion 426 is provided between the communicating holes 424 to enhance rigidity. The reinforcing bent portions 426 are formed to recess or protrude between the communication holes 424 and prevent the rigidity of the rear plate 421 disposed between the communication holes 424 from weakening. The plurality of communication holes 424 are configured such that hot air supplied from the hot air supply section 900 is supplied to the drum 200. At this time, since the drum housing groove 422 accommodates the drum back surface 220, the hot air discharged from the communication hole 424 is guided to be supplied to the suction hole 224. Meanwhile, the clothing processing apparatus according to the present invention further includes a sealing part 450 that seals between the drum housing groove 422 and the drum rear surface 220, and the sealing part 450 is received and attached to the drum housing groove 422.

As a result, the drum receiving groove 422 not only strengthens the rigidity of the rear plate 421 but also provides a space in which the sealing part 450 is installed.

The mounting portion 490 is recessed into the drum accommodating groove 422 in a direction opposite to the direction in which the drum accommodating groove 422 protrudes. The mounting portion 490 is formed by recessing from the inner circumferential surface of the drum housing groove 422 by a depth L2. Since the mounting portion 490 is recessed into the drum housing groove 422, the rigidity of the drum housing groove 422 can be strengthened, and at the same time, the overall rigidity of the rear plate 421 can be strengthened.

Further, the mounting portion 490 is recessed forward from the drum housing groove 422 by an amount L2, so that the mounting portion 490 is disposed closer to the drum rear surface 220. As a result, the distance between the reduction gear 700 and the drum back surface 220, which are attached and fixed to the mounting part 490, can be reduced, and the length of the rotating shaft 740 that connects the reduction gear 700 and the drum back surface 220 can be reduced accordingly. This not only ensures the durability of the shaft 740, but also reduces the angular range in which the rotation shaft 740 is distorted.

Further, the mounting portion 490 is recessed into the drum housing groove 422, and is formed to have a diameter larger than that of the reducer 700 and the drive portion 600. Accordingly, at least a portion of the reducer 700 and the motor section 600 are accommodated in the mounting section 490, thereby reducing the overall thickness of the cabinet 100.

The mounting portion 490 includes a shaft through hole 4291 through which the rotating shaft 740 extending from the reducer 700 passes through the rear plate 421, and a mounting surface 4292 that is provided on the outer peripheral surface of the shaft through hole 4291 and supports the reducer 700. and a mounting groove 4294 extending rearward from the mounting surface 4292 to the drum housing groove. The mounting surface 4292 is provided with a fastening section 4293 that is coupled to the reducer 700 or the coupling section 800 that couples the reducer 700 to the mounting surface 4292 .

On the other hand, at least a portion of the reducer 700 or the motor section 600 is accommodated in the attachment groove 4294. Therefore, a wire support groove 4295 in which a wire for supplying current to the stator 610 is placed is formed by recessing outward from the mounting groove 4294. The mounting groove 4294 is formed larger than the diameter of the drive part (M).

Note that the rear case 420 further includes an air movement hole 423 that transmits hot air supplied from the connector 930 to the duct cover 430. The air that has flowed into the air movement hole 423 flows into the communication hole 424 along the duct cover 430.

FIG. 9 is a diagram illustrating that the motor unit 600 of the clothing processing apparatus according to the present invention is coupled to a speed reducer 700.

The reducer 700 is attached and supported by the attachment part 429 to rotate the drum 200. The stator 610 is directly coupled and fixed to the reducer 700 and is spaced apart from the mounting portion 429 . The rotor 620 is supported by the reduction gear 700 by a drive shaft 630 coupled to the reduction gear 700, and rotates the stator 610.

The stator 610 is coupled to the reducer 700 to form a coaxial structure (S) in which the reducer 700 and the motor section 600 are arranged in parallel. The rotation center of the motor section 600 is arranged on the same axis (S), and the rotation center of the reducer 700 is also arranged on the same axis (S).

As a result, the rotor 620 can also rotate based on the same axis (S), and the rotating shaft 740 extending from the reducer 700 can also rotate based on the same axis (S).

Reducer 700 is directly coupled to stator 610 to fix it. Stator 610 is spaced apart from rear case 420 or mounting portion 429 .

Of course, the stator 610 may be supported in contact with the rear case 420, and if it is directly fixed to the reducer 700, it may be further coupled to the rear case 420.

The stator 610 is coupled to a speed reducer 700, and the speed reducer 700 converts the rpm of the drive shaft 630 to rotate the rotating shaft 740, so that the drum 200 can also rotate about the same axis (S).

Even if the reduction gear 700 vibrates or rotates and the coaxial axis (S) is displaced, the drive shaft 630 and the rotating shaft 740 are arranged parallel to the coaxial axis (S).

As a result, the reducer 700 is coupled and fixed to the rear case 420.

Since the reducer 700 is coupled to the rear of the rear case 420 and the drum 200 is disposed in front of the rear case 420, the rear case 420 is disposed between the drum 200 and the reducer 700.

In the reducer 700, a drum rotating shaft 740 passes through the rear case 420, rotates the drum, and supports the load of the drum via the drum rotating shaft 740.

Further, the rear case 420 is arranged between the drum 200 and the motor section 600. The reducer 700 is disposed between the drum 200 and the motor section 600 and supported by the rear case 420.

At this time, the drum 200 and the motor unit 600 are completely spaced apart from the rear case 420. Therefore, the speed reducer 700 serves as a support center for the drum 200 and the motor unit 600.

Further, the drum 200 is arranged at a distance in front of the rear case 420, the motor section is arranged at a distance at the rear of the rear case 420, and the reducer 700 is connected to the motor section 600 by passing through the rear case from the rear of the rear case. and drum 200 are connected to each other.

Therefore, the drum 200 and the motor section 600 can transmit at least part of the load to the rear case 420 via the reducer 700.

As a result, the motor unit 600, the speed reducer 700, and the drum 200 tilt or vibrate simultaneously with respect to the rear case 420.

Furthermore, since the stator 610 is fixed to the reducer 700, the drive shaft 630 tilts together with the reducer 700 or vibrates simultaneously with the reducer 700.

FIG. 10 is a diagram showing the appearance of the reducer 700.

The speed reducer 700 includes a speed reducer housing 710, 720 that forms an external appearance and houses a gearbox therein. The reducer housing includes a first housing 710 facing the motor part 600 and a second housing 720 facing the drum 200.

Referring to FIG. 10(a), most of the gearbox in the reducer 700 is housed inside the first housing 710, and the second housing 720 shields the inside of the reducer 700. Accordingly, the overall thickness of the reducer 700 can be reduced and the length of the drum 200 can be further extended.

The second housing 720 includes a blocking body 722 that shields the first housing 710 , a coupling body 721 that extends around the blocking body 722 and is coupled to the first housing 710 , and supports a rotating shaft 740 in the blocking body 722 . and a shaft support part 723.

The blocking body 722 has a disk shape, and the coupling body 721 extends from the blocking body 722 toward a portion of the first housing 710 with a constant thickness.

Of course, the coupling body 721 may be provided on the first housing 710 and coupled to the blocking body 722.

The shaft support part 723 prevents the rotation shaft 740 from shifting and maintains the alignment of the rotation shaft 740 and the drive shaft 630.

The coupling body 721 is provided with a fastening part 780 having a certain thickness and fixing the reducer 700 to the stator 610 or the mounting part 429.

The fastening part 780 protrudes from the coupling body 721 and is integrally formed with the coupling body 721. The fastening part 780 includes either a fastening protrusion 781 coupled to the stator 610 or a coupling protrusion 782 coupled to the mounting part 429 . A plurality of fastening protrusions 781 are provided spaced apart along the outer peripheral surface of the coupling body 721, and are spaced apart from each other at the same angle with respect to the shaft accommodating part 713.

Referring to FIG. 10(b), the first housing 710 is formed in multiple stages to accommodate gears of various diameters. Generally, the gearbox coupled to the speed reducer 700 includes a sun gear, a planetary gear that revolves around the sun gear, and a ring gear that accommodates the planetary gear and allows the planetary gear to rotate. The first housing 710 is coupled to a second housing 720, and includes a ring gear housing 711 that accommodates a ring gear, and a planet gear housing 712 that extends away from the ring gear housing 711 and the second housing 720 and accommodates one end of the planet gear. include.

The planetary gear housing 712 is formed to have a smaller diameter than the ring gear housing 711. However, the center of the planetary gear housing 712 and the center of the ring gear housing 711 are arranged coaxially (S) with each other.

A drive shaft 630 rotatably coupled to the rotor 620 is coupled to the planetary gear housing 712 . The drive shaft 630 is inserted into the first housing 710 and rotatably supported within the first housing 710 by a gearbox.

A cleaning part 640 that rotatably supports the rotor 620 is disposed on one surface of the planetary gear housing 712, and a cleaning protrusion 7121 to which the cleaning part 640 is coupled and fixed is provided. The planetary gear housing 712 also includes a cleaning coupling hole 7122 to which the cleaning unit 640 is rotatably coupled.

A plurality of cleaning protrusions 7121 and cleaning coupling holes 7122 are provided at a predetermined angle apart from each other with respect to the drive shaft 630.

The fastening protrusion 781 has a larger cross-sectional area than the coupling protrusion 782 and is thicker. This strengthens the coupling force between the fastening protrusion 781 and the stator 610, making it easier to withstand vibrations transmitted from the stator 610.

The stator 610 is placed on the fastening protrusion 781 and is coupled to the fastening protrusion 781 by another fixing member. The fastening protrusion passes through the stator 610 to form a fastening protrusion hole 7811 to which a fixing member is fastened, and the fastening protrusion hole 7811 has a screw thread formed therein to be coupled to the fixing member.

FIG. 11 is a diagram showing a structure in which a stator 610 is coupled to a reduction gear 700.

The stator 610 includes a ring-shaped main body 611 fixed to the reducer 600, a fixing rib 612 extending from the inner circumferential surface of the main body 611 and coupled to the fastening protrusion 781, and an outer circumference along the circumference of the main body 611. Teeth 614 extending from the surface around which the coil is wound, pole shoes 615 provided at the free ends of the teeth 614 to prevent the coil from coming off, and controls for supplying current to the coil. terminal 616.

The main body 611 has an accommodation space 613 inside, and a plurality of fixing ribs 612 are provided inside the main body 611 at fixed angle intervals with respect to the accommodation space 613, and a fastening protrusion 781 is coupled to the inside of the fixing rib 612. It includes a fixing rib hole 6121 in which a fixing member is provided.

Since the stator 610 is directly coupled to the reducer 700, the reducer 700 is at least partially accommodated and coupled to the stator 610.

In particular, when the speed reducer 700 is housed in the stator 610, the overall thickness of the driving part (M) is reduced, and the volume of the drum 200 can be further expanded. Further, if the reducer 700 is housed in the stator 610, the rotating shaft 740 of the reducer 700 and the drive shaft 630 can be more precisely maintained coaxially.

For this reason, the reducer 700 is formed smaller in diameter than the main body 611. That is, the first housing 710 and the second housing 720 have a maximum diameter smaller than the diameter of the main body 611. Thereby, the reducer 700 is arranged such that at least a portion thereof is housed in the main body 611. However, the fastening protrusion 781 is extended to overlap the fixed rib 612 in the reducer housing. Accordingly, the fastening protrusion 781 is coupled to the fixing rib 612, and a portion of the first housing 710 and the second housing 720 may be located within the main body 611.

The fixing rib 612 includes a first fixing rib 612 a that is directly coupled to the fastening protrusion 781 and a second fixing rib 612 b that is not directly coupled to the fastening protrusion 781 but supports the fastening protrusion 781 and the first housing 710 .

The coupling protrusion 782 is disposed offset from the fastening protrusion 781 and can be prevented from being interfered with by the fastening protrusion 781.

FIG. 12 is a diagram showing a structure in which a motor section 600 is coupled to a reducer 700.

Stator 610 is coupled to reducer 700. At least a portion of the reducer housing may be housed in the main body 611 by being coupled to one surface of the reducer 700 or to a fastening protrusion 781 protruding outward from the housing of the reducer 700 . Thereby, the center of the main body 611, the center of the reducer 700, and the rotating shaft 630 can always be maintained coaxially.

Meanwhile, the rotor 620 accommodates the stator 610 with a predetermined distance from the pole shoes 615 . Since the rotor 620 has a drive shaft 630 fixed to the reducer 700 housed in the main body 611, the distance (G1) between the rotor 620 and the stator 610 is always maintained.

Therefore, the rotor 620 and the stator 610 are prevented from colliding with each other, or the stator 610 is prevented from rotating in a temporarily distorted state, and unnecessary noise and vibration can be prevented from occurring.

On the other hand, an imaginary first diameter line (D1) passing through the center of the reducer 700 and the center of the drive shaft 630, an imaginary second diameter line (D2) passing through the center of the main body 611, and the center of the rotor 620. The imaginary third diameter line (D3) passing through is located at the center of rotation of the drive shaft 630.

As a result, since the reducer 700 itself becomes the rotation center of the drive shaft 630 and the stator 610 is directly fixed to the reducer 700, the drive shaft 630 is prevented from being misaligned with the reducer 700. As a result, the reliability of reducer 700 can be guaranteed.

FIG. 13 is a diagram showing a structure in which the reducer 700 is mounted on the rear case 420.

The motor section 600 is coupled and fixed to a reducer 700, and the reducer 700 is fixed to a mounting section 429 of the rear case 420.

Of course, in the clothing processing apparatus according to the present invention, the speed reducer 700 may be supported in any structure as long as the motor unit 600 can be coupled and fixed to the speed reducer 700.

The reducer 700 is directly connected and fixed to the mounting portion 429, but the mounting portion 429 is generally formed by press-molding the rear case 420 and is therefore thin. Therefore, if the reducer 700 is directly coupled to the attachment part 429, it is difficult for the attachment part 429 to fix the reducer 700. In particular, if the motor part 600 is coupled to the reducer 700, the load of the motor part 600 is also transmitted to the attachment part 429. Therefore, durability cannot be guaranteed because the mounting portion 429 may be bent by the driving portion (M).

Therefore, the clothing processing apparatus according to the present invention further includes a bracket 800 that can reinforce the rigidity of the mounting part 429 and strengthen the durability of the entire rear case 420. Bracket 800 is formed thicker than rear case 420 and is made of a material with greater rigidity than rear case 420.

The bracket 800 is coupled to the mounting part 429 in surface contact to reinforce the rigidity of the mounting part 429, and is coupled to the reducer 700 to fix the reducer 700 to the mounting part 429.

The reducer 700 may be coupled to the bracket 800 while being coupled to the mounting portion 429, or may be coupled only to the bracket 800 and fixed to the mounting portion 429.

Bracket 800 includes a main bracket 810 coupled to mounting portion 429 and also coupled to the reducer housing. Main bracket 810 supports reducer 700 while being fixed to mounting surface 4292.

The main bracket 810 includes a plurality of installation ribs 814 that are directly coupled to the reducer 700, and the installation ribs 814 include an installation rib hole 8143 to which a fixing member fastened to the reducer 700 is coupled.

The main bracket 810 includes a fixing protrusion 8111 formed to engage with a fastening part 4293 provided on the mounting surface 4292. The fastening part 4293 is formed by recessing from the mounting surface 4292, and the fixing protrusion 8111 is inserted into the fastening part 4293 to prevent the main bracket 810 from rotating in the mounting part 429 or changing the installation position due to vibration etc. be able to.

The reducer 700 is coupled to the main bracket 810 and is spaced apart from the mounting part 429 to block noise and vibration generated when the mounting part 429 and the reducer 700 collide.

However, since the reducer 700 receives power from the motor unit 600 and rotates a gearbox therein, considerable vibration occurs. Further, vibrations of the reducer 700 are also transmitted to the drum 200. Therefore, it is necessary to improve the coupling force between the main bracket 810 and the reducer 700.

To this end, the bracket 800 further includes an auxiliary bracket 820 that is coupled to the main bracket 810 and the reducer 700 to fix the reducer 700 to the main bracket 810.

The main bracket 810 and the auxiliary bracket 820 are coupled to surround the reducer 700. The main bracket 810 is coupled to one side of the reducer 700, and the auxiliary bracket 820 is coupled to the other side of the reducer 700 to fix both sides of the reducer 700.

For example, the main bracket 810 is coupled to one side of the coupling protrusion 782, and the auxiliary bracket 820 is coupled to the other side of the coupling protrusion 782 to fix the reducer 700.

The auxiliary bracket 820 may be coupled to the mounting part 429, or may be coupled and fixed to the main bracket 810. Since the main bracket 810 has greater rigidity than the attachment part 429, the auxiliary bracket 820 is more stable when coupled to the main bracket 810.

FIG. 14 is a diagram showing an example of a structure in which the bracket 800 and the reducer 700 are coupled.

Referring to FIG. 14A, the coupling protrusions 782 are smaller in area, size, and thickness than the fastening protrusions 781, but may be formed in greater numbers than the fastening protrusions 781.

The coupling protrusion 782 is disposed offset from the fastening protrusion 781. Further, the coupling protrusion 782 may be arranged parallel to the fastening protrusion 781 or may be arranged at different heights.

The coupling protrusion 782 is formed into a plate shape so as to be supported by the bracket 800 or in surface contact with the bracket 800, and is provided with a coupling protrusion hole 7821 to which a fastening member to be fastened to the bracket 800 is coupled.

Referring to FIG. 14(b), the main bracket 810 includes a main body 811 formed in a ring shape and placed on the mounting surface 4292. The main body 811 has a diameter corresponding to the mounting surface 4292 so as to be in surface contact with the mounting surface 4292 .

A plurality of fixing protrusions 8111 are provided along the periphery of the main body 811, and the fixing protrusions 8111 are spaced apart from each other by the same angle with respect to the center of the main body 811. The fixing protrusion 8111 may be supported by a fastening portion 4293 provided on the mounting surface 4292.

On the other hand, the main body 811 is fixed to the mounting surface 4292 by a fastening member. At this time, a fastening hole to which a fastening member is coupled is formed through the main body 811.

However, since the fixing protrusion 8111 is bent or recessed into the main body 811, it has a higher ability to absorb shock and vibration than the main body 811. Therefore, a fastening hole is formed in the fixing protrusion 8111, and the fastening member passes through the fixing protrusion 8111 and is coupled to the mounting surface 4292.

A disc-shaped seat body 912 is provided on the inner peripheral surface of the main body 811. The seat body 912 is formed to have a diameter smaller than the diameter of the mounting surface 4242, and is a region that does not contact the mounting surface 4242.

If the main body 811 is to be coupled and fixed to the attachment portion 429, the seat body 912 is to extend from the inner peripheral surface of the main body 811 and support the load of the reducer 700.

The seat body 912 is bent and extends from the inner peripheral surface of the main body 811 to strengthen the rigidity of the main bracket 810 and to effectively support the load of the reducer 700.

Reducer 700 may be directly coupled to seat body 912. That is, the coupling protrusion 782 of the reducer can be coupled to the seat body 912.

However, when the diameter of the seat body 912 is relatively large, the inner peripheral surface of the seat body 912 is provided with installation ribs 814 that protrude inward.

The installation rib 814 is formed to have a larger area than the coupling protrusion 782, and has a width in the circumferential direction larger than a length protruding from the seat body 912. Thereby, the installation rib 814 can stably support the load of the reducer 700. The number of installation ribs 814 corresponds to the number of coupling protrusions 782 , and installation rib holes 81413 corresponding to the coupling protrusion holes 7821 are provided.

The installation rib 814 may extend parallel to the seat body 912, or may protrude from one surface of the seat body 912 in the axial direction. The installation rib 814 protrudes from the seat body 912 in the direction toward the speed reducer 700.

Thereby, it is possible to prevent the reducer 700 from protruding excessively to the outside of the bracket 800. In addition, when the main bracket 810 is fastened to the auxiliary bracket 820, the coupling body 782 placed on the installation rib 814 may be guided to be more closely attached to or accommodated in the auxiliary bracket 820.

Referring to FIG. 14(c), the auxiliary bracket 820 includes an auxiliary body 821 formed in a ring shape and mounted on a pedestal 812, and a shielding body 822 extending inward from the auxiliary body 821.

The auxiliary body 821 does not come into contact with the main body 811 and is placed on the pedestal 812. To this end, the auxiliary body 821 is formed to have a diameter corresponding to the base 812. Thereby, even if the main bracket 810 and the auxiliary bracket 820 are coupled via the attachment part 429, it is possible to prevent the auxiliary bracket 820 from interfering with the attachment part 429.

The auxiliary body 821 is supported in direct contact with the base 812 and is coupled to the base 812 by another fastening member. That is, the pedestal 812 includes a pedestal hole 8121 through which the fastening member is coupled, and the auxiliary body 821 includes an auxiliary body hole 8211 at a position corresponding to the pedestal hole 8121.

A shielding body 822 shields the mounting rib 814. That is, the shielding body 822 extends inside the pedestal 812 to a thickness that completely shields the installation rib 814. The shielding body 822 is provided to shield the joint body 782 of the reducer placed on the installation rib 814 and also shield one side of the joint body 782 .

The shielding body 822 is formed to closely fit the installation rib 814 and the coupling body 782 when the auxiliary body 821 is coupled to the base 812 . That is, the coupling body 782 is disposed between the shielding body 822 and the installation rib 814, and the coupling body 782 is fixed and supported by the shielding body 822 and the installation rib 814.

Meanwhile, the shielding body 822 includes a rib accommodating groove 8221 formed in an area corresponding to the installation rib 814 and recessed so that the installation rib 814 is accommodated.

Rib accommodating grooves 8211 are provided corresponding to the number of installation ribs 814 and provided at positions corresponding to the installation ribs 814. The rib accommodating groove 8211 is provided to accommodate the entire installation rib 814 or to press one surface of the installation rib 814.

When the auxiliary bracket 820 is coupled to the main bracket 810, the installation rib 814 and the coupling protrusion 782 are inserted into the rib receiving groove 8211 and fixed.

The coupling protrusion 782 is fixed to the installation rib 814 and the rib receiving groove 8211 by being tightly attached or pressurized.

Accordingly, the auxiliary bracket 820 is prevented from being displaced from the main bracket 810, and the coupling protrusion 782 is also fixed to the rib receiving groove 8211 and the installation rib 814, so that the reducer 700 is stably fixed.

The shielding body 822 is prevented from overlapping the fastening protrusion 781 and further includes a deceleration avoidance hole 8222 that exposes the fastening protrusion 781. The fastening protrusion 781 is exposed from the deceleration avoidance hole 8222, and the stator 610 is stably coupled to the fastening protrusion 781.

In addition, the shielding body 822 further includes a wire avoidance groove 8223 through which the wire connected to the terminal 816 can pass.

Meanwhile, the shielding body 822 is provided to shield a part of the surface of the first housing 710 of the reducer 700. This can prevent the reducer 700 from coming off the bracket 800 due to vibration or impact.

The auxiliary bracket 820 further includes a support hole 824 into which a cleaning protrusion 7121 protruding from the first housing 710 of the reducer 700 is inserted, and a protrusion into which a through protrusion 8141 protruding from the installation rib 814 and inserted into the auxiliary bracket 820 is inserted. A fastening hole 825 is provided.

FIG. 15 is a diagram showing how the bracket 800 is coupled to the reducer 700.

Referring to FIG. 15(a), the main bracket 810 is first coupled to the reducer 700 to fix the reducer 700. A coupling protrusion 782 extending from the reducer housing rests on a mounting rib 814 of the main bracket 810. The coupling protrusion 782 and the installation rib 814 are coupled by a fastening member.

At this time, the fastening protrusion 781 is disposed avoiding the installation rib 814 or exposed inside the main bracket 810.

Referring to FIG. 15(b), when the reducer 700 is placed on the main bracket 810, the auxiliary bracket 820 is coupled to the main bracket 810.

The auxiliary body 821 is coupled to the pedestal 812, and the shielding body 822 shields the internal space of the reducer 700 and the pedestal 812.

In the shielding body 822, the rib receiving groove 824 accommodates the installation rib 814 on which the coupling rib 782 is placed. The coupling rib 782 is disposed and supported between the rib receiving groove 824 and the installation rib 814. As a result, the coupling rib 782 can be prevented from being arbitrarily separated from the installation rib 814.

The shield body 822 is formed such that the fastening protrusion 781 is exposed to the outside by the deceleration avoidance groove 8222. Accordingly, even if the bracket 800 fixes the reducer 700, it does not interfere with the coupling between the motor unit 600 and the reducer 700.

The reducer 700 is coupled to the main bracket 810 and is sufficiently fixed. The auxiliary bracket 820 strengthens the coupling force between the main bracket 810 and the reducer 700 and prevents the reducer 700 from being arbitrarily separated from the main bracket 810.

The reducer 700 is fixed to the main bracket 810 and the auxiliary bracket 820, and is stably fixed to the mounting part 429 even without a separate structure for fixing to the mounting part 429.

Further, the reducer 700 may not be directly coupled to the mounting portion 429 but may be fixed and supported by the bracket 800 and coupled to the mounting portion 429 . Accordingly, even when the reducer 700 is coupled to the motor section 600, it can be stably fixed to the attachment section 429.

FIG. 16 is a diagram showing a state in which the bracket 800 is coupled to the rear case 420.

Referring to FIG. 16(a), the main bracket 810 is coupled to the mounting portion 429 at the front of the rear case 420.

When the drum 200 rotates with clothes stored therein, the drum 200 can apply a force to push the clothes toward the speed reducer 700. The drum 200 is designed to be pressurized or prevented from moving toward the front case 410, especially to prevent the door from being opened by clothing.

At this time, the main body 811 is coupled to one surface of the mounting surface 4292 that does not face the motor section 600 so that the reducer 700 does not separate to the rear of the rear case 420. Therefore, the main bracket 810 can fix the reducer 700 to prevent the reducer from being pushed toward the motor unit 600 and moving.

The main bracket 810 faces the drum rear surface 220 and is coupled to the front of the mounting portion 429 . The attachment portion 429 protrudes from the rear case 420 toward the drum 200. Therefore, in the main bracket 810, the main body 811 is coupled and fixed to one surface of the mounting surface 4292 of the mounting portion 429 that protrudes toward the drum 200.

The fixing protrusion 8111 protruding from the main body 811 is accommodated in a fastening portion 4293 formed on the mounting surface 4292. Of course, the fastening portion 4293 may be accommodated on the opposite side of the fixing protrusion 8111. Since the fixing protrusion 8111 is formed by being pressed from the main body 811, the opposite side becomes a receiving groove.

Therefore, the fastening portion 4293 may protrude from the mounting surface 4292 toward the drum 200 and may protrude away from the drum 200. The fixing protrusion 8111 is formed to protrude in the same direction as the direction in which the fixing protrusion 8111 protrudes from the fastening part 4293 so as to be placed on the fastening part 4293.

Since the main body 811 is coupled to the mounting surface 4292 in surface contact, the thickness of the mounting surface 4292 can be increased. Furthermore, since the main body 811 prevents the mounting surface 4292 from bending, the rigidity of the mounting surface 4292 is strengthened.

When the auxiliary bracket 820 is attached to the main bracket 810, the shielding body 822 of the auxiliary bracket 820 is exposed in front of the rear case 420.

Referring to FIG. 16(b), the auxiliary bracket 820 is coupled to an area exposed to the mounting portion 429 of the main bracket 420 at the rear of the rear case 420, thereby fixing the reducer 700. Since the main body 811 of the main bracket 420 is coupled to the mounting surface 4292, only the base 812 is exposed to the mounting portion 429.

Therefore, the auxiliary bracket 820 is coupled to the pedestal 812 to fix the reducer 700.

As a result, the main bracket 810 is coupled to the front of the rear case 420, and the auxiliary bracket 820 is coupled to the main bracket 810 at the rear of the rear case 420.

As a result, the auxiliary bracket 820 is formed to have a smaller diameter than the mounting surface 4292 to intensively assist in coupling the reducer 700 to the main bracket 810.

FIG. 17 is a diagram showing a structure in which the reducer 700 is coupled to and supported by the rear case 420.

The main body 811 of the main bracket 810 is coupled to the front surface of the mounting surface 4292, and the pedestal 812 is formed with a step on the main body 811 or a groove in which a portion extending from the main body 811 is bent by a certain amount. The overall rigidity of the bracket 810 can be strengthened.

The installation rib 814 includes an extension surface 8141 that extends obliquely toward the rear of the rear case 420 from the pedestal 812, and a support surface 8142 that extends from the extension surface 8141 in a direction parallel to the rear plate 411 and supports the coupling rib 782.

The support surface 8142 includes a fixing hole 8413 to which a fastening member is coupled.

The mounting rib 814 further includes a through protrusion 8144 extending from the support surface 8142 toward the auxiliary bracket 820 .

The coupling protrusion 782 extending from the reducer housing 710 is placed on the support surface 8142 and coupled to the reducer 700 .

The auxiliary bracket 800 has an auxiliary body 821 connected to the base 812, and the shielding body 822 includes an inclined surface 824 recessed from the installation rib along the slope of the extension surface 8141. The inclined surface 824 extends obliquely to the rib accommodating groove 8221 that accommodates the installation rib 814 .

The shielding body 822 includes a protrusion fastening hole 825 into which a through protrusion 8144 is inserted and fixed. A penetrating protrusion 8144 passes through and is supported in the protrusion fastening hole 825 . The position where the auxiliary bracket 820 and the main bracket 810 are coupled can be easily determined by the through protrusion 8144 and the protrusion fastening hole 825. Penetrating protrusion 8144 may pass through coupling body 782.

The mounting portion 429 includes a mounting groove 4294 that is recessed forward from the drum housing groove 423, and the mounting surface 4292 extends from the inside of the mounting groove 4294.

At this time, since the main bracket 810 and the auxiliary bracket 820 are fixed to the mounting surface 4292, at least a portion of the first housing 710 of the reducer is disposed in the mounting groove 4294.

For example, the gearbox 730 housed in the first housing 710 and the second housing 720 is disposed inside the mounting groove 4294.

As a result, the volume occupied by rear case 420 and reduction gear 700 can be minimized.

FIG. 18 is a diagram showing an embodiment of the drive section (M) of the clothing processing apparatus according to the present invention.

A bracket 800 is coupled to the rear case 420, and a reduction gear 700 is coupled to and supported by the bracket 800. The motor section 600 is arranged behind the reduction gear 700 and the rear case 420, and the drum back surface 220 is arranged in front of the rear case 420 and the reduction gear 700.

The stator 610 of the motor section 600 is arranged apart from the rear case 420, and the terminal 616 for supplying current to the stator 610 is arranged near the rear case 420, or can be in contact with the rear case 420, but is not coupled to the rear case 420. and not fixed.

The rotor 620 includes a permanent magnet 623 facing the stator 610, an installation body 622 coupled with the permanent magnet 623 and provided spaced apart from the outer peripheral surface of the stator 610, and an installation body 622 that extends from the installation body 622 and rotates opposite the stator 610. and a rotor body 621. The rotor body 621 is formed into a disk shape larger than the diameter of the stator 610, and the installation body 622 is provided on the outer circumferential surface of the rotor body 621 so as to accommodate the outer circumferential surface of the stator 610. A drive shaft 630 is coupled to the center of the rotor body 621 , and a plurality of inflow holes are formed through the drive shaft 630 and the installation body 622 to inject air into the stator 610 .

The drive shaft 630 is coupled to a stud 631 coupled to the center of the rotor body 621 and extends into the reducer 700 .

A cleaning unit 640 that rotatably supports the inner surface of the rotor body 621 is coupled to the drive shaft 630. The cleaning unit 640 includes a combined cleaning unit 642 coupled to the drive shaft 630 and a support cleaning unit 641 that supports the rotor body 620 with the combined cleaning unit 642.

The cleaning unit 640 can prevent the rotor 620 and the drive shaft 630 from being distorted during rotation.

Of course, the cleaning unit 640 is not coupled to the rotor 620, but may be coupled to the reducer 700 to rotatably support the rotor 620.

A first housing 710 of the reducer 700 faces the rotor body 620, and a second housing 720 is coupled to the first housing 710 and faces the drum rear surface 220.

A gearbox 730 is provided inside the first housing 710 and the second housing 720. The gearbox 730 includes a sun gear 731 provided at or coupled to the free end of the drive shaft 630 , at least one or more planetary gears 732 that rotate while meshing with the sun gear 731 , and planetary gears 732 . The carrier 734 includes a ring gear 733 that is coupled to the outer peripheral surface of the planetary gear 733 to guide the rotation of the planetary gears 732, and a carrier 734 that rotatably supports the plurality of planetary gears 732.

The planetary gears 732 are arranged around the sun gear 731, and each planetary gear 732 has a first planetary body 7321 that rotates while meshing with the sun gear 731 and the ring gear 733, and a first planetary body 7321 that has a smaller diameter than the first planetary body 7321. A gear shaft 7323 rotatably supports the first planet body 7321 and the second planet body 7322 on a carrier 734.

When the sun gear 731 rotates, the planetary gear 732 rotates, causing the gear shaft 7323 to rotate and the carrier 734 to rotate.

The carrier 734 includes a first carrier 7341 coupled to one end of the gear shaft 7323 and a second carrier 7342 coupled to the other end of the gear shaft 7323.

The first carrier 7341 and the second carrier 7342 are formed in a ring shape or a disk shape.

Meanwhile, a rotation shaft 740 extends from the rotation center of the second carrier 7342. The rotation shaft 740 is provided integrally with the second carrier 7342 or extends in combination with the second carrier 7342.

The first housing 710 includes a ring gear housing 711 that fixes the outer peripheral surface of the first planet body 732 or the outer peripheral surface of the ring gear 733, and a ring gear housing that rotatably accommodates the second planet body 732 and the first carrier 7341. A planetary gear housing 712 extending from the planetary gear housing 711 and a shaft accommodating portion 713 extending from the planetary gear housing 712 and rotatably supporting the drive shaft 630 are included.

The ring gear housing 711 forms a side surface of the first housing 710 , and the planetary gear housing 712 forms a part of the side surface of the first housing 710 and a surface facing the rotor 620 . The shaft accommodating portion 713 is formed into a pipe shape extending inside the planetary gear housing 712. The shaft housing portion 713 is disposed in a space where the second planet body 732 is formed to have a smaller diameter than the first planet body 731 . A drive bearing 770 that rotatably supports the drive shaft 630 is provided on the inner peripheral surface of the shaft housing portion 713. A plurality of drive bearings 770 are provided spaced apart along the length of the drive shaft 630.

Accordingly, the drive bearing 770 and the shaft accommodating portion 713 are arranged inside the reducer 700 without protruding to the outside of the reducer 700, so that the interval at which the drive shaft 630 is arranged can be reduced. That is, the volume of the reducer 700 itself can be reduced, and the distance between the reducer 700 and the motor section 600 can also be reduced.

Therefore, the overall thickness of the drive unit (M) can be reduced, and the stator 610 can be coupled closer to the reducer 700 to prevent the drive shaft 630 from being distorted.

Furthermore, by disposing the drive bearing 770 and the shaft housing portion 713 within the reducer 700, the drive shaft 630 approaches the reducer 700, and the reducer 700 is housed within the stator 610. As a result, at least a portion of the speed reducer 700 can be placed by utilizing the space of the motor section 600.

As a result, the length of the drum 200 disposed between the rear case 420 and the front case 410 can be further extended, and the volume of the drum 200 can be expanded.

Meanwhile, the second housing 720 includes a coupling body 721 coupled to the ring gear housing 711, a blocking body 722 that shields the gearbox 730 in the coupling body 721, and a blocking body 722 extending from the blocking body 722 to rotatably support the rotating shaft 740. and a shaft support part 723. The shaft support part 723 is formed in a pipe shape extending from the blocking body 722, and a shaft bearing 760 that rotatably supports the rotating shaft 740 is provided inside the shaft support part 723.

A plurality of shaft bearings 760 are provided along the length of the rotating shaft 740 at a predetermined distance apart.

A free end of the rotating shaft 740 is inserted into and coupled to the drum rear surface 220. At this time, the rotating shaft 740 and the drum back surface 220 are arranged as close as possible. Either of the shaft bearings 760 may be located forward of the drum backside 220.

When the drive shaft 630 is rotated by the rotor 620, the sun gear 731 rotates, and the planetary gears 732 mesh with it and rotate. The first planet body 7321 meshes with the ring gear 733 and rotates, but since the ring gear 733 is fixed, the first planet body 7321 rotates around the sun gear 731 due to reaction.

Planetary gear 732 rotates gear shaft 7323, which in turn rotates carrier 734. When the carrier 734 rotates, a rotating shaft 740 extending from the second carrier 734 rotates.

At this time, the planet gear 732 meshes with the sun gear 731, so even if the planet gear 732 meshes with the sun gear 731 and rotates in the opposite direction, the carrier 734 moves in the same direction as the sun gear 731 due to the reaction while the planet gear 732 rotates to the ring gear 733. As a result, the rotating shaft 740 rotates in the same direction as the sun gear 731.

On the other hand, since the diameter of the outer peripheral surface of the planetary gear 732 and the diameter of the carrier 734 are larger than the diameter of the sun gear 731, the rotating shaft 740 rotates at a lower rpm than the sun gear 731. Therefore, rotating shaft 740 rotates at a lower rpm than drive shaft 630. However, since no energy is wasted other than friction loss, the power transmitted to the drive shaft 630 is transmitted to the rotating shaft 740. Therefore, as the rotational speed of the rotating shaft 740 decreases, the torque that is the rotational force is amplified.

Since the reducer 700 converts the power corresponding to low torque and high rpm generated by the motor section 600 into the power corresponding to high torque and low rpm, the reducer 700 converts the power of the motor section 600 and transfers it to the drum 200. It can be said to communicate.

On the other hand, the a direction, which is the axial direction of the drive shaft 630, and the b direction, which is the axial direction of the rotating shaft 740, are coaxial with each other. At this time, since the drive shaft 630 is supported within the reducer 700 and the stator 610 is also fixedly coupled to the reducer 700, the a direction that the drive shaft 630 forms with the reducer 700 is almost always maintained.

At this time, the gearbox 730 is fixed in the reducer 700 by a gear coupling method, and the rotating shaft 740 is also fixed in the gearbox 730 by the reducer housing 720 and the bearing 770, so that the rotating shaft 740 is separated from the reducer 700. The extending b direction is always maintained.

Therefore, the a-direction and the b-direction form the same axis, and the rotating shaft 740 and the driving shaft 630 can maintain the same axis in most cases.

The rotating shaft 740 and the drive shaft 630 tilt together with the reducer housing or vibrate simultaneously with the reducer housing.

The present invention can be modified and implemented in various forms, and the scope of its rights is not limited to the embodiments described above. Therefore, if the modified embodiment includes the constituent elements within the scope of the claims of the present invention, it can be said to fall within the scope of the rights of the present invention.
