Description

vacuum cleaner station

Technical field

The present invention relates to a vacuum cleaner station that is integrated with a vacuum cleaner to capture dust inside the dust bin of the vacuum cleaner.

Background technique

Generally, a vacuum cleaner is a household appliance that sucks in smaller garbage or dust by using electricity to suck in air, and fills it into a dust bucket in the product. It is usually called a vacuum cleaner.

Such vacuum cleaners can be classified into manual vacuum cleaners in which the user directly moves the vacuum cleaner and performs cleaning, and automatic vacuum cleaners that drive themselves and perform cleaning. Manual vacuum cleaners can be divided into horizontal (canister-type) vacuum cleaners, upright (upright) vacuum cleaners, hand-held vacuum cleaners and stick-type (stick-type) vacuum cleaners according to the shape of the vacuum cleaner.

In the past, most household vacuum cleaners used horizontal vacuum cleaners. However, in recent years, handheld vacuum cleaners and stick vacuum cleaners in which the dust bucket and the main body of the vacuum cleaner are integrated to improve the convenience of use have been increasingly used.

In a horizontal vacuum cleaner, a rubber hose or pipe is used to connect the main body and the suction inlet, and a brush can be assembled to the suction inlet according to the situation.

Handheld vacuum cleaners are vacuum cleaners that maximize portability. Although they are lightweight, the cleaning area may be limited due to their short length. Therefore, it is used for cleaning local places such as desks, sofas or cars.

Stick vacuums can be used standing up, so you can clean without bending down. Therefore, it is beneficial to move around and clean a spacious area. Compared to handheld vacuum cleaners that clean smaller spaces, stick vacuum cleaners can clean wider spaces and can clean high places that are out of reach of your hands. In recent years, stick vacuum cleaners have been provided in a modular form to actively change the types of vacuum cleaners and use them for various objects.

In addition, recently, a sweeping robot that performs cleaning by itself without user's operation has been widely used. The sweeping robot automatically cleans the area to be cleaned by sucking in dust and other foreign matter from the ground while driving in the area to be cleaned.

However, the capacity of the dust bucket used to store collected dust in existing stick vacuum cleaners and sweeping robots is small, causing the user to have the trouble of emptying the dust bucket every time.

Korean Patent Publication No. 2020-0074001 discloses a cleaning device including a vacuum cleaner and a docking station.

In the above-mentioned existing patent document, a cleaning device including a vacuum cleaner having a dust bucket for collecting foreign matter and a docking station connected to the dust bucket to remove foreign matter collected in the dust bucket is disclosed. The docking station is configured to include a suction device for sucking in foreign matter in the dust bucket.

In addition, the above-mentioned conventional patent document is configured to include a trapping unit for trapping foreign matter inside the docking station.

However, in one embodiment of the above-mentioned prior patent document, the collecting part is composed of a dust bag, which causes the inconvenience of requiring periodic replacement. In addition, due to the characteristics of the dust bag's material, dust may scatter during the process of being separated from the docking station for replacement.

US Patent Publication No. 10595692 is a discharge station connected to a sweeping robot, and discloses an embodiment of a discharge station including a canister in the form of a bin and a dust separator.

In an embodiment disclosed in the above-mentioned existing patent document, the dust separator is configured in a conical shape to utilize the principle of centrifugal separation, and is contained inside the barrel. Another embodiment disclosed in the above-mentioned prior patent document is configured such that dust separated from a multi-stage separation device arranged at the upper part of the barrel is collected into the barrel.

However, the discharge station including a dust separator disclosed in the above-mentioned existing patent documents may make it difficult for users to understand the complex structure of the dust separator. As a result, it is difficult for the user to intuitively understand the maintenance method of the dust separator, and thus the discharge station may not be managed hygienically.

In addition, in the case of the embodiment in which the dust separator is included inside the cylinder, there is a problem that the capacity of the inside of the cylinder that can collect dust is reduced by an amount corresponding to the volume of the dust separator.

In the above-mentioned existing patent documents, embodiments not including a dust separator are also disclosed. Embodiments that do not include a dust separator are configured to include a filter wall inside the barrel. The filter wall is arranged in an annular buckle shape. Air containing dust sucked into the barrel is discharged after passing through the filter wall.

However, as mentioned above, in the case of the embodiment including only the filter wall and not the dust separator, a large amount of unseparated dust can only flow into the filter wall instantaneously, so the life of the filter wall is reduced, so that the replacement cycle becomes shorter. question.

Therefore, there is a need to develop a vacuum cleaner station that includes a foreign matter storage member that does not require periodic replacement and does not cause dust scattering problems and has a simple structure so that users can easily perform maintenance such as cleaning the foreign matter storage member.

In addition, even if regular replacement is not required, the user needs to manually empty the dust trapped in the foreign matter storage member, so there is a need to develop a vacuum cleaner station with a structure that can extend the dust emptying cycle even if it includes a foreign matter storage member with the same capacity.

Referring to FIGS. 1 to 5 , the vacuum cleaner system 1 of the embodiment of the present invention may include a vacuum cleaner station 10 and a vacuum cleaner 20 . On the other hand, in this embodiment, some of the components may be omitted, and additional components may not be excluded.

The vacuum cleaner station 10 is a device configured to perform an operation of sucking in and removing dust inside the dust bucket 21 of the vacuum cleaner 20, and can be combined with the vacuum cleaner 20 to perform such a dust suction operation. At this time, the vacuum cleaner 20 combined with the vacuum cleaner station 10 may be a sweeping robot that travels autonomously and performs cleaning actions.

Before describing the structure of the vacuum cleaner station 10 , the structure of the vacuum cleaner 20 will be described with reference to FIG. 2 .

The vacuum cleaner 20 can automatically clean the area to be cleaned by sucking in foreign matter such as dust from the ground while traveling in the area to be cleaned. The vacuum cleaner 20 may include a distance sensor for detecting a distance from obstacles such as furniture or office supplies or walls provided in the cleaning area, and left and right wheels for movement. The vacuum cleaner 20 may be integrated with the vacuum cleaner station 10 . The dust sucked into the dust bucket 21 of the vacuum cleaner 20 can be collected into the inside of the vacuum cleaner station 10 through the suction hole 121 described later.

The vacuum cleaner 20 may include a dust discharge hole 22 . At this time, the dust discharge hole 22 may be disposed on the bottom surface of the dust bucket 21 of the vacuum cleaner 20, so that the dust bucket 21 of the vacuum cleaner 20 and the suction flow path 140 described below can be connected. As an example, the dust discharge hole 22 may be in the shape of a quadrangular hole. However, in the embodiment of the present invention, the shape of the dust discharge hole 22 is not limited.

The vacuum cleaner 20 may include a discharge cover 23 . At this time, the discharge cover 23 may be formed in a shape corresponding to the dust discharge hole 22 and may be provided to close the dust discharge hole 22 . For this purpose, the discharge cover 23 may be disposed at the dust discharge hole 22 . In addition, one side of the discharge cover 23 may be fixed to the dust discharge hole 22 to form a fixed end, and the other side may form a free end. With such a configuration, when suction is generated to the dust bucket 21 of the vacuum cleaner 20, the fixed end can be in a fixed state, and the free end can move downward (towards the suction hole 121 of the coupling part 120). Thereby, the dust discharge hole 22 can be opened. If the suction force toward the dust bucket 21 of the vacuum cleaner 20 disappears, the free end of the discharge cover 23 can move upward, so that the dust discharge hole 22 can be blocked again. As mentioned above, according to the moving direction of the free end, the discharge cover 23 can connect or seal the dust bucket 21 and the suction pipe 126 of the vacuum cleaner 20 .

The vacuum cleaner 20 may include corresponding terminals 24 for charging of the battery when combined with the vacuum cleaner station 10 . The corresponding terminal 24 may be disposed at a position capable of being connected to the charging terminal of the vacuum cleaner station 10 when the vacuum cleaner 20 is coupled. As an example, a pair of corresponding terminals 24 may be arranged on the bottom surface of the vacuum cleaner 20 . When the corresponding terminal 24 and the charging terminal are electrically connected, power can be supplied from the vacuum cleaner station 10 to the vacuum cleaner 20 to charge the vacuum cleaner 20 .

Hereinafter, the structure of the vacuum cleaner station 10 will be described with reference to FIG. 1 and FIGS. 3 to 5 .

The vacuum cleaner station 10 may include a station body 100 and a dust separation module 200 .

Before describing the specific structure of the vacuum cleaner station 10, first define the directions mentioned throughout the description. When the direction in which the vacuum cleaner 20 moves in order to be combined with the vacuum cleaner station 10 is defined as the front and rear direction, the vacuum cleaner 20 can be combined with the vacuum cleaner station 10. The side of is defined as the front. In addition, the opposite side to the front is the rear. In addition, the direction parallel to the long axis A1 of the station main body 120 may be defined as the up-down direction.

The station main body 100 is configured to be combined with the vacuum cleaner 20 and suck dust from the dust bucket 21 of the vacuum cleaner 20 into the interior, and may form a long axis A1 extending in the up-down direction.

The station body 100 may include a housing 110 formed with an interior space surrounded by a plurality of outer walls. The space can accommodate various components to protect them from external impacts. For example, the components may be the dust collection motor 140 that generates suction force into the dust bucket 21 of the vacuum cleaner 20 , a power module provided to charge the vacuum cleaner 20 , a control circuit that controls the overall operation of the vacuum cleaner station 10 , etc. The housing 110 can be combined with the vacuum cleaner 20 to collect dust in the dust bucket 21 of the vacuum cleaner 20 .

The housing 110 may form the outer shape of the station body 100 through a plurality of outer walls. Therefore, the housing 110 may form the long axis A1 extending in the up-down direction. The long axis A1 of the housing 110 may be coaxial with the long axis A1 of the station body 100 . The housing 110 may have an outer shape similar to a square prism. More specifically, the housing 110 has a shape similar to a square prism as a whole, and may have a shape in which a part combined with the vacuum cleaner 20 is bent rearward. However, the outer shape of the housing 110 can be variously changed within the functional scope of being able to be combined with the vacuum cleaner 20, able to form a space inside the vacuum cleaner station 100, and able to accommodate and protect the above-mentioned components.

On the other hand, the plurality of outer walls may include a front wall 110a disposed in front, a back wall 110b facing the front wall 110a and disposed toward the rear, and side walls 110c and 110d disposed between the front wall 110a and the back wall 110b. . A coupling part 120 coupled to the vacuum cleaner 20 may be disposed on the front wall 110a. The front wall 110a may have a shape bent rearward in a shape corresponding to the combination with the vacuum cleaner 20. Compared with the front wall 110a, the back wall 110b may have a flat surface shape. Therefore, in the indoor space where the vacuum cleaner station 10 is installed, the back wall 110b can be arranged adjacent to the wall of the indoor space, thereby improving the space utilization efficiency of the indoor space. Additionally, a power cord for powering the vacuum cleaner station 10 may exit at the rear wall 110b. The side walls 110c, 110d may be provided on the left and right sides respectively to connect the front wall 110a and the back wall 110b. At this time, at least one corner connecting the front wall 110a and the side walls 110c, 110d or the back wall 110b and the side walls 110c, 110d to each other may be set to have a prescribed radius of curvature.

A part of the housing 110 may be configured to be openable and closable between the internal space of the housing 110 and the outside of the housing 110 . For example, a housing opening cover (not shown) configured to be openable and closable may be provided in a part of the front wall 110a. The casing opening cover may be configured to open and close an adjacent area where a high-efficiency particulate air filter 150 (described later) is disposed.

The station body 100 may further include a coupling part 120 coupled with the vacuum cleaner 20 . The vacuum cleaner 20 can climb to the upper surface of the coupling part 120 to be coupled with the vacuum cleaner station 100 . The coupling portion 120 may be disposed on one of the outer walls constituting the housing 110 . For example, like the embodiment of FIG. 1 , the coupling part 120 may be disposed on the front wall 110a. Later, the structure of the coupling part 120 will be described with reference to FIG. 6 .

The station body 100 may further include a suction flow path 130 .

Referring to FIGS. 3 to 5 , the suction flow path 130 may be arranged in the internal space of the housing 110 . The suction flow path 130 is coupled to the coupling part 120 and may be configured in the form of a hollow tube so as to be able to suck dust inside the dust bucket 21 of the vacuum cleaner 20 . That is, air containing dust discharged from the dust bucket 21 of the vacuum cleaner 20 can flow inside the suction flow path 130 . One end of the suction flow path 130 is coupled to the suction hole 123 of the coupling part 120 . Therefore, when the vacuum cleaner 20 is coupled to the vacuum cleaner station 10 , the dust bucket 21 of the vacuum cleaner 20 and the suction flow path 130 can communicate through the suction hole 123 . The other end of the suction flow path 130 is connected to the dust separation module 200 . The air flowing through the suction flow path 130 can flow into the dust separation module 200 , and dust can be separated in the dust separation module 200 .

The suction flow path 130 may include a first suction flow path 130a and a second suction flow path 130b. The longitudinal axis A3 of the first suction flow path 130a may be arranged parallel to the long axis A1 of the station main body 100. One end of the second suction flow path 130b may be connected to the first suction flow path 130a. In addition, the second suction flow path 130b may extend in the front-rear direction on the lower side of the coupling part 120. To put it another way, the first suction flow path 130a may be configured to extend in the vertical direction, and the second suction flow path 130b may be configured to extend in the horizontal direction. The first suction flow path 130a may be arranged parallel to the longitudinal axis of the dust collecting motor 140. The longitudinal axis A3 of the first suction flow path 130a and the longitudinal axis of the dust collection motor 140 may be arranged at a predetermined distance from each other.

The other end of the second suction flow path 130b may be connected to the suction hole 123 . Therefore, when the vacuum cleaner 20 is combined with the coupling part 132, the other end of the second suction flow path 130b can communicate with the dust bucket 21 of the vacuum cleaner 20.

The station main body 100 may also include a dust collection motor 140 .

The dust collection motor 140 may be disposed in the internal space of the housing 110 . The dust collecting motor 140 can provide suction force from the inside of the dust bucket 21 to the outside, so that the dust inside the dust bucket 21 of the vacuum cleaner 20 moves through the suction flow path 130 . More specifically, when the dust collecting motor 140 is driven, an air flow is generated from the upper part to the lower part of the station main body 100, and at the same time, suction force from the dust separation module 200 described below to the dust collecting motor 140 can be generated. Inside the suction flow path 130 , the direction of action of the suction force may be consistent with the direction of the dust sucked into the dust bucket 21 .

The station body 100 may also include a high efficiency particulate air filter 150 .

Referring to FIG. 5 , the high-efficiency particulate air filter 150 may be accommodated inside the housing 110 and may be disposed at a suitable position where the air that has passed through the dust collection motor 150 is finally filtered before being discharged to the outside of the housing 110 . In a possible embodiment, the high-efficiency particulate air filter 150 may be disposed at the lower part of the dust collection motor 140 . Alternatively, in a feasible embodiment, the high-efficiency particulate air filter 150 may be disposed in front of the dust collection motor 140 . Alternatively, in a feasible embodiment, the high-efficiency particulate air filter 150 may be disposed behind the dust collection motor 140 .

The station main body 100 may further include a control unit (not shown).

The control part can be accommodated in the internal space of the housing 110 and can determine whether the vacuum cleaner 20 is coupled to the vacuum cleaner station 10 and overall control subsequent suction actions. At this time, the control unit may include all types of devices capable of processing data, such as a processor. Here, a “processor” may refer to, for example, a data processing device built in hardware that has a physical structure of a circuit in order to execute a function represented by codes or instructions included in a program. Examples of such a data processing device built into hardware may include a microprocessor (microprocessor), a central processing unit (CPU), a processor core (processor core), a multiprocessor (multiprocessor), or an ASIC. (application-specific integrated circuit, application-specific integrated circuit), FPGA (field programmable gate array, field programmable gate array) and other processing devices, but the scope of the present invention is not limited thereto.

The station main body 100 may also include a power module (not shown).

The power module can be accommodated in the internal space of the housing 110 and can convert AC power received from the outside of the housing 110 into DC power. When the vacuum cleaner 20 is combined with the coupling part 120, power can be supplied to the vacuum cleaner 20 to power the vacuum cleaner. 20 batteries are charged.

The housing 110 of the station main body 100 may be provided with an exhaust part 160 (see FIG. 1 ). The exhaust part 160 may include a plurality of holes penetrating the inside and outside of the housing 110 so that the air that has passed through the high-efficiency particulate air filter 150 is discharged to the outside of the housing 110 . In a possible embodiment, the exhaust portion 160 may be formed on the front wall 110a. Alternatively, in a feasible embodiment, the exhaust portion 160 may be formed on the back wall 110b. Alternatively, in a feasible embodiment, the exhaust portion 160 may be formed on the side walls 110c and 110d.

FIG. 6 is a perspective view showing a coupling part coupled with the vacuum cleaner in the vacuum cleaner station of FIG. 1 .

Referring to FIG. 6 , the coupling part 120 may include a coupling surface 120a. The coupling surface 120a is a surface formed by bending the front wall 110a of the housing 110, and may refer to a surface facing upward. In addition, the coupling surface 120a may refer to a surface facing the bottom surface of the vacuum cleaner 20 based on the state in which the vacuum cleaner 20 is coupled. The vacuum cleaner 20 can approach and climb the coupling portion 120 from the front, and can be placed on the coupling surface 120a. The shape of the coupling surface 120a may correspond to the shape of the bottom surface of the vacuum cleaner 20. For example, the bonding surface 120a may be in a rectangular shape. However, in possible embodiments, the shape of the coupling surface 120a may be different from the shape of the bottom surface of the vacuum cleaner 20.

The coupling part 120 may include a rolling part 121 through which the left and right wheels of the vacuum cleaner 20 pass when the vacuum cleaner 20 climbs for coupling. When the coupling portion 120 is viewed from the front, the rolling portions 121 may be disposed adjacent to the left and right end portions of the coupling portion 120 . The distance between the left and right rolling parts 121 may correspond to the distance between the left and right wheels of the vacuum cleaner 20 so as to guide the movement of the left and right wheels of the vacuum cleaner 20 . In addition, the rolling part 121 may be in a shape that is recessed downward compared to the coupling surface 120a of the coupling part 120 to prevent the left and right wheels of the vacuum cleaner 20 from deviating from the movement path when moving. That is, the rolling part 121 may be defined as a region recessed downward compared to the coupling surface 120 a adjacent to the rolling part 121 .

In addition, the rolling part 121 may be provided with a wheel mounting part 122 that supports the left wheel and the right wheel of the vacuum cleaner 20 to prevent the vacuum cleaner 20 from moving when it is combined with the coupling part 120 . The wheel placement portion 122 may be defined as a curved and concave area formed on the rolling portion 121 so as to be able to surround and support the left and right wheels of the vacuum cleaner 20 .

A plurality of protrusions protruding upward at predetermined intervals may be provided on the upper surface of the rolling portion 121 . The plurality of protrusions form concavities and convexities on the rolling portion 121, thereby preventing the left wheel and the right wheel from sliding.

The coupling part 120 may include a suction hole 123 provided at a position corresponding to a position where the dust bucket 21 of the vacuum cleaner 20 is disposed based on the state in which the vacuum cleaner 20 is coupled to the coupling part 110 . The suction flow path 130 and the dust bucket 21 can be connected through the suction hole 123 . The suction hole 123 may be provided with a protrusion 124 formed by protruding upward on the coupling surface 120a. The protruding portion 124 may protrude to a height that can compensate for the positional difference between the dust discharge hole 22 of the vacuum cleaner 20 and the coupling surface 120 a when the wheels of the vacuum cleaner 20 are placed on the wheel mounting portion 122 . By providing the suction hole 123 in the protruding portion 124, it is possible to prevent the suction force from being reduced when the dust bucket 21 communicates with the suction flow path 130.

At this time, a caster guide portion 125 having the same height as the coupling surface 120a may be formed on the protruding portion 124 to guide the movement of the caster. To put it another way, in order to keep the left and right sides of the vacuum cleaner 20 balanced, the protruding portions 124 can be formed at predetermined intervals on the left and right sides respectively, and the protruding portions 124 can be spaced apart from each other. A region of the coupling surface 120a is defined as a caster guide 125.

The suction hole 123 may be disposed at a position corresponding to the position where the dust discharge hole 22 of the vacuum cleaner 20 is disposed when the vacuum cleaner 20 is coupled to the coupling part 120 . The suction hole 123 may be formed in a shape corresponding to the dust discharge hole 22 of the vacuum cleaner 20 . As an example, the suction hole 123 may be in the shape of a quadrangular hole.

On the other hand, the second suction flow path 130b may be accommodated in the internal space of the housing 110 disposed at the lower part of the coupling part 120, and the end of the second suction flow path 130b may be connected to the suction hole 123 (see FIG. 5 ). That is, when the discharge cover 23 of the vacuum cleaner 20 opens the dust discharge hole 22, the second suction flow path 130b and the inside of the dust bucket 21 can be connected through the suction hole 123.

The combination part 120 may include a charging part 126 that is electrically connected to the vacuum cleaner 20 and supplies power to charge the vacuum cleaner 20 . The charging part 126 may include charging terminals 126a and 126b respectively provided on the left and right sides of the coupling part 120 when viewed from the front. When the vacuum cleaner 20 is combined with the coupling part 110, the corresponding terminal 24 of the vacuum cleaner 20 is electrically connected to the charging terminals 126a and 126b, and the power module provided inside the housing 110 supplies power to the vacuum cleaner 20, so that the vacuum cleaner 20 can be charged. The distance between the left and right charging terminals 126a, 126b and the distance between the corresponding terminals 24 of the vacuum cleaner 20 may be substantially the same.

Hereinafter, a preferred embodiment of the dust separation module 200 included in the vacuum cleaner station 10 of the present invention will be described.

Fig. 7 is a perspective view of the dust collecting bucket and the exhaust air moving portion as viewed from above. In FIG. 7 , the dust bucket shielding plate 217 and the housing shielding plate 222 are omitted to explain the internal structures of the dust bucket 211 and the exhaust air moving part.

Referring to FIGS. 4 and 7 , the dust separation module 200 may include a dust collecting part 210 and an exhaust air moving part 220 .

The dust collecting part 210 may include a dust collecting bucket 211.

The dust collecting bucket 211 is disposed on the upper part of the station body 100 and may be configured to collect dust flowing together with the air. The dust bucket 211 may be disposed on the outer upper part of the housing 110 .

The dust bucket 211 may include a dust bucket body 2111 and a dust bucket cover 2112 .

The dust bucket main body 2111 may provide a storage space for storing collected dust. The dust bucket main body 2111 may be formed in a cylindrical shape, and the longitudinal axis A2 of the dust bucket main body 2111 may be arranged parallel to the long axis A1 of the housing. In addition, the longitudinal axis A2 of the dust bucket main body 2111 may be arranged parallel to the long axis A3 of the second suction flow path 130b (see FIG. 3 ).

The lower side of the dust bucket main body 2111 is coupled to the dust bucket cover 2112 so that it can be selectively opened and closed. The upper side of the dust bucket main body 2111 can be closed by the dust bucket shielding plate 217 (see FIG. 1 ). The dust bucket shielding plate 217 may constitute the top surface of the dust bucket body 2111 and the top surface of the vacuum cleaner station 100 at the same time. The dust bucket shielding plate 217 may be integrally formed with the dust bucket main body 2111 . The dust bucket main body 2111 can be made of a transparent material visible from the inside. Thus, the user can grasp the degree of dust collection and can easily determine whether the dust collected in the dust collection bucket 211 needs to be emptied. The dust bucket main body 2111 can be made of washable material. For example, the dust bucket body 2111 may be made of plastic material.

In the case where the dust storage member provided in the vacuum cleaner station 100 is a bag type dust bag, the user needs to replace the dust bag regularly. At this time, if the capacity of the dust bag is small, it needs to be replaced frequently, so there is a problem that user convenience is reduced. On the other hand, if the capacity of the dust bag is large, it is necessary to wait for the dust to fill up the dust bag, so the replacement cycle becomes longer. , which may cause the problem of bacteria multiplying inside the dust bag.

In contrast, as in the embodiment of the present invention, in the case where a dust collecting bucket 211 of a bin type is provided as a dust storage member, the dust collecting bucket 211 can be used semi-permanently without replacement, and therefore is not only economical but also economical , and is also capable of being cleaned so that dust can be emptied and cleaned whenever required, thus having the advantage of being able to manage the vacuum cleaner station 10 more hygienically.

On the other hand, the dust bucket main body 2111 may be provided with an inlet 2111a through which air flows.

The inlet 2111a may communicate with the suction flow path 130 on the other side of the suction flow path 130 (the side opposite to the side where the suction flow path 130 is connected to the dust bucket 21 of the vacuum cleaner 20), so that air can flow in. More specifically, the inlet 2111a may be provided in the form of a hole penetrating the dust bucket main body 2111 to communicate the suction flow path 130 and the inside of the dust bucket main body 2111.

The inflow port 2111a may be formed with a predetermined area on the wall surface of the dust collecting bucket 211 that forms the accommodation space and is arranged in the radial direction of the dust collecting bucket 211 . More specifically, in an embodiment in which the dust bucket main body 2111 has a cylindrical shape, the dust bucket 211 can pass through the upper wall of the dust bucket formed by the dust bucket shielding plate 217, in the length direction of the dust bucket main body 2111. The accommodating space is formed by a cylindrical side wall of the dust bucket arranged in a radial direction with respect to the axis and a lower wall of the dust bucket formed by a dust bucket cover 2112 described later. At this time, the inlet 2111a may be formed on the wall surface of the side wall of the dust collection bucket. That is, the air sucked from the dust bucket 21 of the vacuum cleaner 20 can flow in from the side of the dust bucket 211 . As described above, by configuring the arrangement in which air flows in from the side of the dust bucket 211, the overall height of the vacuum cleaner station 10 can be reduced, and the usability of the indoor space can be further improved.

The dust bucket main body 2111 may be provided with a discharge port 2111b for discharging air.

The discharge port 2111b may be provided in the shape of a hole penetrating the dust bucket main body 2111 so as to communicate with the inside of the dust bucket main body 2111 and the exhaust air moving part 220 described later.

The discharge port 2111b may be formed with a predetermined area on the wall surface of the dust collecting bucket 211 that forms the accommodation space and is arranged in the radial direction of the dust collecting bucket 211 . That is, the discharge port 2111b may be formed on the wall surface of the dust bucket side wall similarly to the inflow port 2111a. The discharge port 2111b and the inflow port 2111a may be arranged at a predetermined distance from the side wall of the dust collection bucket.

Next, the dust bucket cover 2112 will be described.

FIG. 8 is a cross-sectional view showing a cover assembly portion for opening and closing the dust bucket cover. FIG. 9 is a front view of the cover assembly portion of FIG. 8 . FIG. 10 is a view showing the cover of FIG. 8 except for the button cover. FIG. 11 is a diagram of the assembly part showing a state in which the dust bucket cover is opened.

The dust bucket cover 2112 may include a cover body 2112a and a hinge part 2112b. The cover body 2112a may be formed to seal the lower surface of the dust bucket body 2111. The cover main body 2112a can rotate downward based on the hinge part 2112b. The hinge part 2112b may be arranged adjacent to the exhaust air moving part 220 described below. If the dust bucket cover 2112 is coupled with the coupling protrusion 2111c of the dust bucket main body 2111 through the coupling hook 2112c, the lower side surface of the dust bucket main body 2111 can be closed.

On the other hand, the dust bucket 211 may further include a cover assembly part 2113. The dust bucket cover 2112 can be separated from the dust bucket through the cover assembly part 2113. More specifically, the lid assembly part 2113 allows the dust bucket cover 2112 to rotate to open and close one end of the dust bucket 211 in the longitudinal direction. The cover assembly part 2113 may be arranged on the opposite side of the hinge part 2112b. The cover assembly part 2113 may be disposed on the outer surface of the dust bucket main body 2111 and may be disposed adjacent to the lower end of the dust bucket main body 2111 .

The cover assembly part 2113 may include: a button 2113a to which an external force is applied; and a hook pressing protrusion 2113b connected to the button 2113a. When an external force is applied to the button 2113a, the hook pressing protrusion 2113b moves and interacts with dust collection. The coupling hook 2112c connected to the bucket cover 2112 is elastically deformed; and the button cover 2113c is configured to cover at least a part of the coupling hook 2112c.

More specifically, the buttons 2113a may be provided on the left and right sides respectively. When an external force is simultaneously applied to the left and right buttons 2113a in the direction of the coupling hook 2112c (arrow direction in FIG. 10), the hook pressing protrusion 2113b connected to the button 2113a may Move toward the coupling hook 2112c and apply pressure to the coupling hook 2112c. The coupling hook 2112c can elastically deform in a direction to release coupling with the coupling protrusion 2111c by the hook pressing protrusion 2113b. When the coupling of the dust bucket cover 2112 and the dust bucket main body 2111 is released, the dust bucket cover 2112 rotates downward based on the hinge portion 2112b to open the dust bucket main body 2111. With this configuration, dust stored in the dust collecting bucket 211 can be easily removed.

On the other hand, the dust collecting part 210 may further include a screen 212 disposed at the discharge port 2111b of the dust collecting bucket 211 to filter dust in the air discharged from the dust collecting bucket 211.

Referring back to FIG. 7 , the mesh net 212 may be formed to have the same shape and area as the area of the discharge port 2111b. The screen 212 may be configured to block the discharge port 2111b. That is, the screen 212 may be configured to form part of the outer shape of the dust bucket main body 2111 . The screen 212 is a member formed with a plurality of holes, and may be made of a metal material, but is not limited thereto. The screen 212 does not allow dust with larger particles to pass through the dust bucket body 2111, so the dust can be collected into the dust bucket 211. The screen 212 may be disposed on the side wall of the dust bucket 211 together with the discharge port 2111b. That is, the exhaust air discharged from the dust bucket main body 2111 may be discharged from the side of the dust bucket 211. As described above, by configuring the arrangement in which the exhaust air is discharged from the side of the dust bucket 211, the overall height of the vacuum cleaner station 10 can be reduced, and the usability of the indoor space can be further improved.

Hereinafter, the structure of compressing the dust collected in the dust collecting bucket 211 will be described with reference to FIGS. 12 to 17 .

Fig. 12 is a view overlooking the dust collecting bucket and the exhaust air moving part from an upper surface; Fig. 13 is a cross-sectional view taken along line A-A in Fig. 12; Fig. 14 is a cross-sectional view taken along line B-B in Fig. 12; Fig. 15 is a cross-sectional view taken along line B-B in Fig. 12; FIG. 12 is a cross-sectional view taken along line C-C, and FIG. 16 is a perspective view of the dust bucket and the exhaust air moving part viewed from the lower side, with the dust bucket cover omitted.

The dust collecting part 210 may further include a rotating unit 213.

Referring to FIGS. 12 to 16 , the rotation unit 213 may be disposed inside the dust bucket 211 , and may be configured to rotate along the inner circumferential surface of the dust bucket 211 about the longitudinal axis of the dust bucket 211 to collect dust. Dust inside barrel 211. More specifically, the rotation unit 213 may include a rotation shaft 2133 and a rotation plate 2131.

The rotating shaft 2133 is arranged along the length direction of the dust collecting barrel 211 and can receive power from the outside of the dust collecting barrel 211 to rotate. The rotation axis 2133 may be coaxial with the axis in the length direction of the dust bucket 211 . The lower end of the rotating shaft 2133 may be connected to the dust bucket cover 2112 to be able to receive power from the outside. The rotating shaft 2133 extends adjacent to the upper end of the dust bucket 211 . As an example, the rotating shaft 2133 can be combined with the inner surface of the upper wall of the dust bucket.

The rotating plate 2131 may be coupled to the rotating shaft 2133 to rotate together with the rotating shaft 2133, and may be disposed in a space between the rotating shaft 2133 and the radial inner peripheral surface of the dust bucket 211. More specifically, the rotating plate 2131 may have one end of the rotating plate 2131 connected to the rotating shaft 2133 and the other end facing toward the radial outer side of the dust collecting bucket body 2111, that is, from the center of the dust collecting bucket 211 to the dust collecting side. The shape of the barrel's side wall extending. As an example, the rotating plate 2131 may be formed in a quadrilateral flat plate shape. The vertical length of the rotating plate 2131 may be formed to be similar to the length of the dust bucket main body 2111 . When the rotating plate 2131 rotates together with the rotating shaft 2133, the wide surface of the rotating plate 2131 contacts the wide surface of the compression plate 214 described later, so that dust accumulated between the rotating plate 2131 and the compression plate 214 can be compressed.

The dust collection part 210 may further include a compression plate 214 .

Referring to FIGS. 12 to 16 , the compression plate 214 may be configured to be fixed on one side inside the dust bucket 211 to compress dust collected by rotation of the rotation unit 213 . More specifically, the compression plate 214 may be formed such that one end portion is connected to the inner surface of the side wall of the dust collection bucket, and the other end portion extends toward the radial inner side of the dust collection bucket 211 . The compression plate 214 may be formed in substantially the same shape as the rotation plate 2131 . As an example, the compression plate 214 may be formed in a quadrilateral flat plate shape.

The rotating unit 213 may rotate in a direction approaching the compression plate 214 to compress dust collected between the rotating unit 213 and the compression plate 214 . More specifically, when the rotation shaft 2133 rotates, the rotation plate 2131 and the compression plate 214 gradually approach and the wide surfaces of the rotation plate 2131 and the compression plate 214 come into contact, so that dust collected between them can be compressed.

On the other hand, the rotating shaft 2133 may rotate in the first direction to compress dust between the rotating plate 2131 and the compression plate 214, and then rotate in a second direction opposite to the first direction. The rotation direction of the rotation shaft 2133 can be controlled by the dust compression motor 215 described later.

With this configuration, the dust collected in the dust collecting bucket 211 can be compressed and stored. Therefore, there is an effect of increasing the capacity of dust that can be collected compared to the actual capacity of the dust bucket 211, thereby increasing the dust storage efficiency inside the dust bucket 211, thereby improving user convenience. In addition, if the dust inside the dust bucket 211 is compressed, there is an effect that the dust will not scatter when the dust in the dust bucket 211 is emptied. In addition, the direction of the rotating shaft 2133 can be switched between the first direction and the second direction, so dust can be compressed in both directions of the compression plate 214, thereby maximizing the dust storage efficiency of the dust bucket 211.

On the other hand, the rotation unit 213 may further include a scraper 2132.

Referring back to FIG. 7 , the scraper 2132 may be provided to rotate together with the rotation shaft 2133 in a state of contact with the inner peripheral surface of the dust bucket 211 . The scraper 2132 may be combined with the rotating plate 2131 on the opposite side where the rotating shaft 2133 is provided. At this time, one side of the scraper 2132 may be configured to be in contact with the inner peripheral surface of the dust bucket 211 . That is, one edge of the scraper 2132 may be configured to contact the inner surface of the side wall of the dust bucket. Therefore, when the scraper 2132 rotates together with the rotating plate 2131, it can rotate while scraping the inner surface of the side wall of the dust bucket. The scraper 2132 may be made of flexible material. As an example, the scraper 2132 may be made of rubber material.

On the other hand, the above-mentioned screen 214 may be disposed in a part of the wall surface in contact with the scraper 2132 . In an embodiment in which the scraper 2132 is disposed in the radial direction of the dust bucket body 2111, the screen 214 may be disposed on the side wall of the dust bucket. That is, the discharge port 2111b for discharging air from the dust bucket main body 2111 may be arranged on the side wall of the dust bucket. With this configuration, the scraper 2132 can scrape off dust adhering to the screen 214 .

In the case where the vacuum cleaner station does not include a dust separator such as a cyclone unit, it has the effect of being able to easily clean the dust bucket due to its simple structure. However, a large amount of dust that does not pass through the dust separator adheres to the screen. This may cause problems with the screen becoming clogged. The embodiment of the present invention has the advantage of being able to solve the clogging even if the screen 214 is clogged by providing a scraper 2132 that can scrape off the dust attached to the screen 214 .

FIG. 17 is a conceptual diagram for explaining the positional relationship between the rotating plate and the screen inside the dust bucket.

Referring to FIG. 17 , the vertical length of the scraper 2132 may be set to be larger than the vertical length of the discharge port 2111b. In addition, the scraper 2132 may be configured to pass through the entire area of the discharge port 2111b when the scraper 2132 rotates.

More specifically, the height H1 from the lower end surface of the dust bucket body 2111 to the lower end of the scraper 2132 may be smaller than the height H1 from the lower end surface of the dust bucket body 2111 to the discharge port 2111b. The height H3 of the lower end, and the height H2 from the lower end surface of the dust bucket body 2111 to the upper end of the scraper 2132 is greater than the height H2 from the lower end surface of the dust bucket body 2111 to the upper end of the discharge port 2111b The height of the part is H4.

With such a configuration, the scraper 2132 can scrape the entire area of the screen 212 disposed at the discharge port 2111b while removing dust adhering to the screen 212 .

Hereinafter, the dust compression motor 215 that provides power to rotate the rotation unit 213 will be described.

FIG. 18 is a perspective view showing the rotation unit and the dust compression motor, and FIG. 19 is a perspective view showing the separation of the rotation unit and the dust compression motor.

Referring to FIGS. 18 and 19 , the dust collecting part 210 may further include a dust compression motor 215 .

The dust compression motor 215 may provide power to rotate the rotating shaft 2133. The dust compression motor 215 may be disposed outside the dust bucket 211 and may be connected to the rotating shaft 2133 through the dust bucket cover 2112 . As an example, as in the embodiment of the present invention shown in FIG. 18 , the dust compression motor 215 may be connected to the rotation shaft 2133 through the dust compression gear part 216 . The dust compression gear part 216 may include a first gear 2161 and a second gear 2162 . The first gear 2161 and the second gear 2162 may be configured in the form of circular gears. The first gear 2161 may be connected with the shaft of the dust compression motor 215 . The second gear 2162 may be meshed with the first gear 2161 . The second gear 2162 may be connected with the rotation shaft 2133.

However, the connection between the dust compression motor 215 and the rotation shaft 2133 is not limited to the form of this embodiment. In a feasible embodiment, the dust compression motor 215 may also be directly connected to the rotation shaft 2133 through a dust compression motor shaft that is configured to penetrate the cover body 2112a of the dust bucket cover 2112.

A sensor capable of detecting the degree of rotation of the rotating shaft 2133 may be disposed on one side of the dust compression motor 215 to control the stopping of the rotating shaft 2133. The sensor may be a microswitch.

The dust compression motor 215 can be controlled by the control part. As described above, the rotation shaft 2133 may switch the rotation direction between the first direction and the second direction, which may be performed by switching the rotation direction of the dust compression motor 215 . For example, if the dust compression motor 215 is driven to rotate in the forward direction, the rotating shaft 2133 may rotate in the first direction, and if the dust compressing motor 215 is driven to rotate in the reverse direction, the rotating shaft 2133 may rotate in the second direction.

The dust compression motor 215 may be configured to be separable from the dust bucket 211 . Figure 20 discloses a bottom view of the dust collecting bucket and the exhaust air moving part.

Referring to FIGS. 19 and 20 , the second gear 2162 may include a rotation shaft connection portion 2162a. The rotation shaft connecting portion 2162a can be inserted into the coupling groove 2112d coupled to the dust bucket cover 2112. The shape of the end portion of the rotation shaft connecting portion 2162a may be configured to match the shape of the coupling groove 2112d. Thereby, when the rotation shaft connecting portion 2162a is inserted into the coupling groove 2112d, the rotation shaft 2133 and the second gear 2162 can be coupled. Therefore, when the second gear 2162 rotates, the rotation shaft 2133 may rotate together.

FIGS. 21 to 23 are diagrams for explaining a dust compression process based on rotation of the rotation unit 213 .

Referring to FIGS. 21 to 23 , the rotating plate 2131 may rotate in the first direction and stop after compressing dust between the rotating plate 2131 and the compression plate 214 . The rotating plate 2131 may switch the rotation direction in the second direction and then rotate and compress the dust between the rotating plate 2131 and the compression plate 214 before stopping. As described above, the control of rotation and stop of the rotating plate 2131 can be performed by the control part controlling the dust compression motor 215 . With this configuration, dust can be stored in a compressed state near the compression plate 214, and even when the dust bucket cover 2112 is opened to remove the stored dust, the dust can be cleanly removed without scattering.

Hereinafter, the exhaust air moving part 220 will be described with reference again to FIG. 7 and FIG. 12 to FIG. 16 .

As described above, the dust separation module 200 may include the exhaust air moving part 220 .

The discharge air moving part 220 may be connected to the discharge port 2111b, and may provide a space in which the air discharged from the dust bucket 211 flows in and moves. More specifically, the exhaust air moving part 220 may include an exhaust air moving part housing 221, a suction flow path connection part 223, and a dust collection motor connection part 224.

The exhaust air moving part 220 may be arranged on the upper part of the station main body 100 (see FIG. 1 ). The exhaust air moving part 220 may be arranged behind the dust bucket 211 . That is, the dust collecting part 210 and the exhaust air moving part 220 may be arranged side by side in the front-rear direction on the upper part of the station main body 100. In a possible embodiment, the dust collecting part 210 and the exhaust air moving part 220 may be arranged side by side in the left-right direction. Through such a configuration, the overall height of the vacuum cleaner station 10 can be reduced, and the utilization of indoor space can be further improved.

On the other hand, the cover assembly part 2113 for opening the dust bucket cover 2112 may be disposed toward the front, and the exhaust air moving part 220 may be disposed on a side where the cover assembly part 2113 is not located. For example, the exhaust air moving part 220 may be disposed on the side where the hinge part 2111b of the dust bucket 211 is located. With this arrangement, the user's action of applying external force to the cover assembly portion 2113 in order to open the dust bucket cover 2112 is not hindered.

The discharge air moving part case 221 may form a space into which the air discharged through the discharge port 2111b flows. A part of the outer shape of the exhaust air moving part housing 221 may be formed into a shape surrounding the dust bucket 211, and the remaining part may be formed into a shape corresponding to the shape of the housing 110 of the station main body 100. More specifically, the exhaust air moving part housing 221 may include: a first surface 221a disposed to surround the outer peripheral surface of the dust bucket side wall; and a second surface 221b forming a vacuum cleaner station together with the back wall 110b of the housing 110 100 back profile. In addition, the exhaust air moving part housing 221 may further include a third surface 221c and a fourth surface that connect the first surface 221a and the second surface 221b and form the side profile of the vacuum cleaner station 100 together with the side walls 110c and 110d of the housing 110 221d.

In a feasible embodiment, the first surface 221a may be formed into an integral form with a part of the side wall of the dust bucket. That is, the first surface 221a constitutes one surface of the exhaust air moving part housing 221 and also constitutes the dust bucket side wall. At this time, the inflow port 2111a and the discharge port 2111b may be formed on the first surface 221a.
