Description

Tumble Washer Dryer

technical field

The present invention relates to a drum type washing and drying machine, in more detail, relates to a drum type washing machine with a drying function, which can continuously perform each process from washing to drying or only select the drying process. Tumble washer dryer.

Background technique

The washing and drying machine can not only continuously perform various processes such as washing, rinsing, dehydration, and drying, but also perform a separate drying process for drying wet clothes. Especially in the drum-type washing and drying machine, since the clothes can be dried in the rotating drum arranged in the horizontal direction or in the inclined drum inclined to the horizontal direction, the same drying effect as that of the clothes dryer dedicated to clothes can be obtained. Drying effect and ease of use.

However, there are many kinds of clothes. Due to the different types and compositions of fibers and the types of clothes, when the clothes are stirred in the rotating drum and warm air is blown evenly to all the clothes inside to tumble dry clothes, some Clothes are easily damaged. This is the case for sweaters, lingerie, etc., which are delicate items that are not suitable for tumble drying. In order to be able to dry these delicate clothes, someone has proposed a static drying solution that can choose to blow warm air to dry clothes under the state that the rotating drum is stopped at this time (for an example, refer to Japanese Laid-Open Publication 2005- Bulletin No. 152476).

Drum-type washer-dryer is different from general drum-type washing machine and washer-dryer. The rotating drum is arranged horizontally. The top of the washing machine shell is provided with a laundry input port. An opening is formed at a position corresponding to the above-mentioned laundry input port, and such an opening is closed by the door body during operation, forming a special form called "top loading" method of taking out/putting in laundry from above . When implementing static drying in this drum-type washer-dryer, the door body on the water tub and the rotating drum must be opened from the laundry inlet, and the drying auxiliary device is installed in the rotating drum. Such an assisting appliance for drying clothes is provided with a shelf portion processed by using metal wires for carrying clothes, and a leg portion for supporting the shelf portion on the inner wall surface of the rotary drum.

During the drying operation, the clothes are placed on the drying auxiliary appliance, and the static drying operation mode is selected and executed. At this time, the rotating operation of the rotary drum is stopped, and the warm air heated by the heater is blown into the rotary drum to deprive the clothes of moisture; then, the air that has captured the moisture of the clothes is discharged to the outside of the tub for dehumidification, Then it is heated by the heater again and sent to the rotating drum again to form air circulation to dry the clothes.

It is easy to imagine that when inserting the drying auxiliary device from above to the bottom of the rotating drum in the above-mentioned drum type washer-dryer, since the drying auxiliary device needs to be inserted into a deep position from the narrow opening, the It is very difficult to operate. In the case of a general drum-type washing machine, it is much easier to insert the shelf-shaped auxiliary device for placing clothes into the rotating drum provided with the opening facing the front after opening the front door. As a prior art for realizing the above-mentioned operation, a device using static drying clothes in a clothes dryer is known (for an example, refer to Japanese Laid-Open Publication No. Hei 10-305197).

In the above clothes dryer, a shelf-shaped auxiliary device for placing clothes may be installed in the rotary drum. After the above-mentioned auxiliary device is installed in the rotary drum, clothes can be placed on it, and then the static drying operation mode can be selected and implemented. In this way, the rotation operation of the rotary drum is stopped, and the warm air heated by the heater is sent into the rotary drum to dry the clothes.

As mentioned above, in the above-mentioned existing drum-type washer-dryer, since it is necessary to insert the drying auxiliary device for placing clothes into the lower part of the rotary drum from the laundry inlet provided on the top surface of the washing machine casing, the Clothes are dried statically, and therefore, it is very difficult to insert the drying aid into a deep position. In addition, because the structure of the above-mentioned washing machine is also different from that of general washing and drying machines, the openings for taking out/putting in clothes are arranged on the body parts of the water tub and the rotating drum, so it is necessary to make the washing machine with a larger area It will be quite difficult to insert the drying aid, and it is also conceivable that the work of placing the clothes on the drying aid will not be easy. Therefore, it is desirable to have a structure in which the auxiliary device for placing clothes can be inserted into the rotary drum from the laundry inlet provided on the front side of the washing machine casing. From this point of view, the structure of the laundry dryer shown in the prior art seems to be more suitable.

Since there is no washing function in the laundry dryer, the structure is simpler than that of the drum type washer dryer, and it is relatively easy to construct a structure in which an auxiliary device for static drying is installed in the rotary drum. However, in a drum-type washer-dryer with a washing function and an additional drying function, it is relatively difficult to install a shelf capable of unfolding the clothes and having a large storage area.

Contents of the invention

The purpose of the present invention is to solve the above-mentioned problems in the prior art.

The present invention is characterized in that: before the drying process, the drying rack inserted from the laundry input port is set up in the rotating drum in a substantially horizontal direction, and the control unit controls according to the operation selection input. , stop the rotation of the rotating drum, make the drying mechanism work, and make the drying air circulate in the rotating drum to implement static drying operation. There are many stirring protrusions on the inner wall of the rotating drum, so The drying rack is installed on the stirring protrusion in such a way that its installation part wraps the stirring protrusion formed on the top of the stirring protrusion, and the two stirring protrusions are arranged at the same height position below, so that the drying rack The clothes rack is erected between the two stirring protrusions.

After adopting the above-mentioned structure, when drying clothes, firstly, the clothes drying rack is arranged in the rotating drum, and the clothes to be dried are placed on it, and then the static clothes drying operation command is input. At this time, the control unit stops the rotation of the rotary drum to allow the drying air to circulate for static drying. After the clothes are unfolded on the drying rack with the ventilation structure, the clothes can be blown with drying air on the inside and outside, which can improve the effect of clothes drying. In addition, since the laundry input port of the rotary drum faces the front side of the washing machine casing, when the door on the front of the washing machine casing is opened, the drying rack can be easily installed in or taken out from the rotary drum. Operation.

In the above structure, the clothes drying rack is formed by connecting multiple rack surfaces with a hinge structure. In this way, the surface of the shelf can be folded, and when the clothes drying rack is put into or taken out from the opening of the rotating drum whose diameter of the opening is smaller than the inner diameter, it can be taken out from the side where the width becomes smaller after being folded. Put it in, so as to constitute a drying rack with a larger clothes storage area.

In addition, the drying rack is made of flexible panels. In this way, by bending it along the circumference of the opening portion of the rotary drum, it can be put into or taken out from the rotary drum, so that a drying rack with a large storage area can be formed.

In addition, the drying rack is erected in a state in which both ends thereof are placed between a plurality of agitation protrusions provided on the inner wall surface of the rotary drum. In this way, the clothes drying rack can be stably installed in the rotary drum.

In addition, the heat pump is the most suitable choice for the air heating and dehumidification device that constitutes the clothes drying mechanism. In this way, even if the heating temperature of the drying air is set low, the heat pump with a high dehumidification effect can produce the required drying performance, and it is suitable for static drying of delicate clothes that are easily damaged or shrunk by the high temperature drying air. A heat pump is an ideal heating and dehumidification unit when it comes to clothing.

The technical effects produced by the present invention are as follows. The present invention can place the clothes on the drying rack arranged in the rotary drum for static drying operation. After the clothes are unfolded on the drying rack formed with a ventilation structure, the drying air can be blown to the inside and outside of the clothes, which can improve the drying effect. In addition, since the opening of the rotary drum faces the front side of the washing machine casing, the drying rack can be easily installed in or taken out from the rotary drum after opening the door provided on the front of the washing machine casing. , and can install a drying rack with a larger clothes storage area.

Detailed ways

FIG. 1 shows the structure of a drum-type washer-dryer 1 in an embodiment of the present invention, in which the characteristic composition of the present invention, that is, the structure of the drying mechanism, is highlighted.

As shown in Figure 1, the rotary drum 5 is located inside the tub 3, and the drum drive motor 4 is installed on the back of the tub 3, and the rotating shaft 17 of the rotary drum 5 is rotated by the bearing 16 provided on the tub 3 This rotating shaft 17 is driven to rotate by the drum driving motor 4, constituting the tub unit 10 above. The tub unit 10 is supported in the washing machine casing 2 through a shock-absorbing structure, and the rotation axis of the rotary drum 5 is in an inclined state in which the front side is tilted upward. The tub 3 and the rotary drum 5 are respectively provided with openings on the front side, and after opening the door 8 provided on the front of the washing machine casing 2, laundry can be put in or taken out from the laundry inlet 6 of the rotary drum 5 . When the machine door 8 is closed, the bellows 43 arranged at the opening of the water tub 3 is in close contact with the inner surface of the machine door 8, so the inside of the water tub 3 will become a watertight and airtight space for washing, rinsing, and dehydration. Water and air will not leak to the outside during various processes such as drying clothes.

By installing the tub unit 10 obliquely in the washing machine casing 2, the heat pump unit 20 can be installed in the space formed in the lower part of the back side of the washing machine casing 2. In order to install the washer-dryer 1 in the existing place where the area of the waterproof seat is limited, the volume of the washing machine casing 2 is limited, and a relatively large water tub unit 10 and a water tank unit 10 for For components that perform water supply and drainage operations, there is little remaining space. However, if the structure of the heat pump unit 20 is made very compact, it can be installed in the washing machine housing 2 without increasing the volume of the washing machine housing 2 .

The cabinet 21 of the heat pump unit 20 is equipped with a compressor 27, a heat absorber 28 and a heat radiator 29 (see FIG. The air connection pipe 32 is connected, and the heated air exhaust port 31 communicated with the radiator 29 is connected with the exhaust connection pipe 33 . On the bottom surface corresponding to the heat sink 28 in the cabinet 21, a water storage part 34 for receiving condensed water dripping from the heat sink 28 is provided, and the water stored in the water storage part 34 passes through the dust filter 35 Finally, it is discharged from the storage water outlet by a drainage pump not shown in the figure.

The heat absorber 28 and the heat radiator 29 are installed in the cabinet 21 as a heat absorbing/radiating unit. One surface of the heat absorber 28 and the heat radiator 29 is opposite to each other at a certain distance, and the other surface and the wall surface of the cabinet 21 respectively form a space to form an air flow channel. The two ends are respectively formed by a pair of side wall panels 37 to support, thereby forming the air passage from the air suction space on the heat absorber 28 side through the heat absorber 28 and the heat release 29, and then entering the exhaust space on the heat radiator 29 side. In addition, the heat absorber 28 is disposed on an incline with its upper part close to the heat radiator 29 , and the upper part of the heat radiator 29 is also inclined to the heat absorber 28 , facing each other in an inclined state. In this way, the air flow passage can be effectively ensured, and the heat pump unit 20 can be disposed in a limited space formed behind the tub 10 .

The heat pump unit 20 having the above structure is connected to the tub 10 through the air supply channel as shown in FIG. 1 . An air inlet 11 is provided on the back side of the water tub 3, and an air outlet 12 is provided on the side wall surface, and a heating air blowing duct 13 is provided between the air inlet 11 and the exhaust connecting pipe 33 of the heat pump unit 20. connection, the air outlet 12 and the air suction connecting pipe 32 of the heat pump unit 20 are connected by the moisture absorption air blowing duct 14 provided with the air blowing fan 15, thus forming the air supply for drying clothes. aisle.

The side wall of the rotating drum 5 is provided with a plurality of water holes 9, so that the water and air between the drum and the water tank 3 can circulate freely, and the bottom surface is provided with a plurality of air introduction holes communicating with the air inlet 11. 26. Therefore, the dry heated air sent from the heat pump unit 20 through the heated air blowing duct 13 can be introduced into the rotary drum 5 from the bottom surface of the drum through the air inlet 11 as shown by the arrow in FIG. 1 . In addition, the hot air will become moisture-absorbing air after depriving the clothes contained in the rotary drum 5 of moisture, and enter the tub from the water hole 9 and the laundry inlet 6 as indicated by the arrows in FIG. 1 . 3, and then discharged from the exhaust port 12 into the air blowing pipe 13 for moisture absorption, and finally discharged into the suction connecting pipe 32 of the heat pump unit 20.

As shown in FIG. 3 , in the drum-type washer-dryer 1 with the above structure, the front of the washing machine housing 2 is provided with an operation display part 44 for selecting an operation mode, inputting an operation command, and displaying the working state. By inputting the selection status of the operation process and the time setting of each process from the operation display part 44, the selection command is input into the control unit not shown in the figure, and then the operation of each part is controlled by the control unit to implement A series of operations from washing to drying can also be freely selected to only perform the drying process.

When washing, the machine door 8 is opened, the laundry is thrown into the rotary drum 5, an instruction is input from the operation display unit 44, and the operation is started. After the operation starts, water and detergent are supplied to the tub 3 from a water supply pipeline not shown in the figure, and then the drum driving motor 4 drives the rotating drum 5 to rotate, and the washing process starts. The rotary drum 5 brings the laundry to the top through a plurality of stirring wings 7 on its inner wall surface, and then makes it fall from the top to play the role of beating the laundry, and repeat such operations to wash. After the washing process is completed, the rinsing process and the dehydration process are also carried out, and finally the washing is finished. When selecting and inputting the operation mode of continuously implementing from the washing process to the drying process, the control unit enters the drying process after the washing operation is completed. In addition, when only wet laundry is dried, only the drying process may be performed.

In the drying process, dehydrated laundry or wet clothes (hereinafter collectively referred to as clothes) are loaded into the rotary drum 5 first, and then the drying process is performed. In the drying process, the rotary drum 5 rotates at a speed corresponding to the drying process to agitate the clothes. At the same time, the heat pump unit 20 and the blower fan 15 are driven to start circulation of the drying air.

As shown in Figure 2, the heat pump unit 20 compresses the refrigerant through the compressor 27, and under the action of its pressure, the refrigerant flows from the compressor 27 into the refrigerant pipeline 41, and passes through the radiator 29, throttling unit 42, suction Circulation is carried out in the heater 28 and the compressor 27. When the heat of the compressed refrigerant flows into the heat radiator 29, it dissipates heat to the air in contact with the fins on the refrigerant pipeline 41 arranged in the heat radiator 29, thereby heating the sent air and forming Heat the air. The heated air is sent from the exhaust air space through the exhaust connecting pipe 33, the heated air blowing duct 13 to the rotary drum 5 through the air inlet 11, and the moisture is taken from the stirred clothes to become hygroscopic air, and then from the exhaust air. The air port 12 discharges into a blast duct 14 for hygroscopic air. The hygroscopic air sent into the hygroscopic air blowing duct 14 enters the air suction space of the heat pump unit 20 through the suction connecting pipe 32 and the hygroscopic air inlet 30 . The low-pressure refrigerant decompressed by the throttling unit 42 flows in the heat absorber 28. When the moisture-absorbing air flows through the heat absorber 28, the sensible heat and latent heat in it are taken away to be dehumidified; the dehumidification process produces The condensed water drops into the water storage part 34, and the dehumidified and dried air enters the radiator 29 and is heated again, thereby forming an air circulation. The drainage pump not shown in the figure operates once at regular intervals to discharge the water stored in the water storage part 34 into the water tub 3;

The working mode of the heat pump drying mechanism that heats and dehumidifies the air used for drying clothes by the heat pump unit 20 is: the heat absorbed by the heat absorber 28 is recovered through the refrigerant, and then the heat is released from the radiator 29 . Therefore, more heat can be added to the clothes than the energy input to the compressor 27, thereby shortening the drying time and realizing energy saving. In this way, compared with the method of using the heater as a heat source to heat the air and then blow it on the clothes for drying, even if the temperature of the heated air is set at a lower level, due to the higher dehumidification capacity of the heat pump drying method, high drying efficiency can be achieved. Efficient drying and suitable for drying clothes that are not resistant to heat.

As mentioned above, when the rotary drum 5 is rotated and the clothes are stirred while drying, the delicate clothes such as sweaters or lingerie are easily damaged. Therefore, the drum-type washer-dryer 1 of the present embodiment In the embodiment, the drying process may be implemented in a state where the rotation of the rotary drum 5 is stopped, and static drying may be performed. When performing static drying, the clothes are placed flat in the rotary drum 5, and an instruction to perform only the drying process is input from the operation display unit 44, and at the same time, the time setting for the drying operation is input.

When the static drying command is input, the control unit stops the rotation of the rotary drum 5 and activates the blower fan 15 and the heat pump unit 20 . In this way, heated air is sent into the rotary drum 5 from the bottom surface of the rotary drum 5, and the heated air passes through the clothes to take away the water, and then enters into the tub 3 from the water hole 9 on the wall surface of the drum; or, the heated air comes into contact with the clothes The heated air enters into the tub 3 from the water hole 9 and the laundry input port 6 after robbing the water. The heated air becomes hygroscopic air after depriving moisture, enters the hygroscopic air blowing duct 14 from the outlet 12 of the water tub 3, and then is sent to the heat pump unit 20, dehumidified by the heat absorber 28, and then dehumidified by the radiator 29. Heated, blown into the rotating drum 5 again as heated air. Because such air circulation is constantly repeated, so the clothes are gradually dried.

When drying clothes statically, compared with the case where the clothes are placed on the wall of the rotary drum 5, if the clothes are placed in the inner space of the rotary drum 5, the heated air can be blown more evenly, and the penetration of the heated air will also be enhanced, thereby Allows for more efficient drying. In order to put clothes in the inner space of the rotary drum 5, as shown in FIG.

The opening of the rotary drum 5, that is, the opening diameter of the laundry input port 6 is smaller than the inner diameter of the rotary drum 5, so it is difficult to install the drying rack 50 having a certain area of the clothes placement surface into the rotary drum 5. . For this reason, the drying rack 50 in this embodiment adopts a folding structure as shown in Figures 4 and 5, and its two parts can be folded. After folding, the width will be narrowed, and it can be inserted from the laundry inlet 6. into the rotating drum 5. After the drying rack 50 inserted into the rotary drum 5 is set in a substantially horizontal state, the folded upper side is opened to form a wide clothes placement surface. In addition, in order to keep the installation position of the drying rack 50 in the rotary drum 5 constant and to ensure a stable installation state, the drying rack 50 is placed on the stirring blade 7 provided on the inner wall surface of the rotary drum 5 superior.

As shown in Fig. 4 and Fig. 5, the rear placement surface 51 and the front placement surface 52 in the drying rack 50 are connected by a hinge structure part 53, and the two sides of the rear placement surface 51 and the front placement surface 52 are provided with The mounting part 54 on the stirring wing 7. Many air vents 55 are provided on the rear placing surface 51 and the front placing surface 52, so that the heated air can easily blow to or pass through the clothes placed thereon. In addition, a handle 56 is also provided on the front side of the front placement surface 52, so that it is easy to pull the front placement surface 52 under the state that the front placement surface 52 is folded on the rear placement surface 51 as shown in Figure 5 (a). Therefore, the operability in the rotary drum 5 is improved. In addition, the handle 56 is provided with a finger hole 57 near the side of the rear placement surface 51. When the shelf is taken out from the rotating drum 5 and folded into a folded state again, it is convenient to operate after having such a finger insertion hole.

As shown in Figure 6, in the above-mentioned structure, the cross-sectional shape of the stirring blade 7 arranged on the inner wall surface of the rotating drum 5 is roughly triangular, and its height and width are closer to the inner side, and the mounting part 54 is installed on the stirring blade 7. The stirring protrusion 7a formed on the top can wrap the stirring protrusion 7a to ensure the stability of the installation. As shown in FIG. 7 , stirring blades 7 are provided at three positions on the inner wall surface of rotary drum 5 at the same pitch. When installing the drying rack 50, the rotary drum 5 can be rotated by hand so that the two stirring wings 7 are paralleled below and approximately at the same height, so that the drying rack 50 can be erected on the two stirring wings. Between wings 7.

When the folded drying rack 50 is placed on the agitating wing 7 , the two claws 54 a provided on the mounting portion 54 of the rear placement surface 51 are clamped on the agitating protrusion 7 a. Since the rotating drum 5 is inclined, the clothes drying rack 50 can slide to the bottom surface of the rotating drum 5 and be fixed at a predetermined position if it is pushed a little. Next, hook the handle 56 with fingertips, pull up the front placement surface 52, and then press lightly, the claws 54a provided on the mounting portion 54 of the front placement surface 52 can clamp the stirring protrusion 7a. Simultaneously, as shown in Figure 1, the central protrusion 52a protruding toward the front side of the front placement surface 52 will enter in the front panel 6a forming the laundry input port 6, and the abutting parts 52b on both sides will withstand it. The inner wall surface of the front panel 6a, so the installation state of the drying rack 50 can be kept stable.

After the static drying is finished, it needs to be taken out from the rotary drum 5 on the clothes rack 50 . At this time, the fingertips can hook the finger hole 57, pull up the front placement surface 52, fold it onto the rear placement surface 51 to form a folded state, and then pick up the entire shelf, so the drying rack 50 can be easily placed. take out. When taken out to the outside of the rotary drum 5, since it is in the same folded state as when inserted, the width becomes narrower, so the direction of the rotary drum 5 can be rotated to change the vertical and horizontal state, and the laundry can be put into 6 and taken from the laundry in a narrow state. out. Therefore, the clothes drying rack 50 can be easily taken out.

When performing the operation of taking out/putting into the drying rack 50 for the rotating drum 50 in order to implement the static drying action, or placing clothes on the installed drying rack 50, if the drum in this embodiment If the rotary drum 5 is arranged at an incline like that of the conventional washer-dryer 1, the degree of bending can be greatly reduced, and the convenience of operation can be significantly improved. Although the main purpose of developing this inclined drum type drum type washing machine or washer-dryer in which the rotating drum 5 is inclined is to make washing easier to take out/put in from the rotating drum 5, and to have less space on the front side. It can also be installed in a toilet, etc., but its structure is also very effective when performing static drying.

In addition, although the above-mentioned drying rack 50 is folded into two parts of the rear placement surface 51 and the front placement surface 52 by the hinge structure part 53, so as to reduce its width when put in/out from the rotary drum 5, it can also be made The whole drying rack 50 is made of a flexible material, which can be bent and then inserted when passing through the laundry inlet 6 . Since the laundry input port 6 is a circular opening, after the drying rack 50 is bent into an arc shape along the circular periphery, it can be easily inserted into the rotary drum 5; Afterwards, under the rebound action of elastic deformation, it will return to the plane shape again, forming the clothes placement surface.

To sum up, the present invention provides such a drum-type washer-dryer.
