Description

Vacuum cleaner dock

The invention relates to a vacuum cleaner docking station coupled to a vacuum cleaner to collect dust in a dust box of the vacuum cleaner.

In a stick vacuum cleaner (hereinafter referred to as a vacuum cleaner), since the capacity of the dust box for storing collected dust is very small, it is inconvenient for the user to empty the dust box every time.

Therefore, vacuum cleaner docking stations configured to suck and collect dust from a dust box through the suction force of a dust collection motor are increasingly used, so that users do not have to manually remove dust from the dust box.

The vacuum cleaner docking station includes: a casing; a dust collection motor arranged in the casing; and a dust bag collector for storing collected dust. The vacuum cleaner dock is configured to be coupled to a vacuum cleaner or a dust bin of the vacuum cleaner.

The convenience of a vacuum cleaner dock is that it automatically empties the vacuum cleaner's dust bin. In addition, since the volume of the dust bag contained in the vacuum cleaner docking station is larger than that of the dust box provided in most vacuum cleaners, there is an advantage that the dust treatment cycle becomes longer.

On the other hand, dust bag collectors have a simple structure, and the entire dust bag can be discarded in the trash without the need to separately dust or clean its interior. Therefore, dust bag collectors are advantageous in terms of user convenience.

However, since the inside of the dust bag cannot be cleaned, dust bags must be purchased and replaced regularly, making the cost burdensome for some users.

In this regard, US Registered Patent Publication No. 10595692 is proposed as a prior art document.

This prior art document discloses an embodiment in which an evacuation dock docked with a sweeping robot has a box collector.

Unlike dust bags, the inside of a "box-type" collector is easy to clean, so as long as the dust stored in it is removed, the collector can be used semi-permanently.

However, some users may find it inconvenient to remove dust and clean the collector because these two tasks must be done separately.

As a result, if the collector has any fixed single type, it will be difficult to satisfy the different preferences of users.

At the same time, US Registered Patent Publication No. 10595692 discloses an embodiment, in which an evacuation docking station docked with a sweeping robot includes a box-type metal can and a dust separator.

In an embodiment disclosed in this prior art document, the dust separator is formed to have a cone shape to use the principle of centrifugal force and is contained in a metal can. According to another embodiment disclosed in the prior art document, dust separated from a multi-stage separation device disposed above a metal can is collected in the metal can.

However, there is a limitation in that the docking station can only be connected to a machine vacuum cleaner, and there is no structure to collect dust stored in a stick vacuum cleaner by connecting the stick vacuum cleaner to the docking station.

Furthermore, this prior art document shows a structure in which air sucked from the dust box of the sweeping robot is introduced into the side of the dust box. Therefore, when air is introduced to the side of the dust box, there is a limitation that the introduced dust is likely to flow only backward.

Furthermore, the prior art document also discloses an embodiment without a dust separator. According to this embodiment without a dust separator, the filter wall is arranged inside a metal can and is formed in an annular form. Air containing dust drawn into the metal can passes through the filter wall and is then exhausted.

However, in the case of the embodiment having only a filter wall without a dust separator, there is a problem in that the life of the filter wall is shortened and the replacement cycle of the filter wall is reduced, because a large amount of dust that cannot be filtered out immediately enters the filter In the wall of the vessel.

In addition, the user is required to manually remove dust collected in the foreign matter storage member. Therefore, there is a need to develop a vacuum cleaner docking station that has a structure that can increase the dust removal cycle even if the foreign matter storage member has a certain capacity.

The present invention aims to solve the above-mentioned problems of conventional vacuum cleaner docking stations. The object of the present invention is to provide a vacuum cleaner docking station that allows users to select and use dust bags or dust boxes according to their own preferences.

Another object of the present invention is to provide a vacuum cleaner docking station including a dust box, which has a larger dust storage capacity and higher efficiency, so as to have a longer dust removal cycle.

Yet another object of the present invention is to provide a vacuum cleaner docking station capable of maximizing airflow efficiency during dust collection.

Another object of the present invention is to provide a vacuum cleaner docking station in which dust will not fly away during dust collection.

It is a further object of the present invention to provide a vacuum cleaner docking station containing a dust box, the internal parts of which can be easily separated and cleaned.

One embodiment is a vacuum cleaner dock including: a housing; a coupling portion disposed in the housing and including a coupling surface to which at least a portion of the vacuum cleaner is coupled; and a collector attachable And detachably coupled to the inside of the casing, disposed below the coupling part, and collecting dust in the dust box of the vacuum cleaner; and a dust collection motor, which is stored in the casing, disposed below the collector, and generates The suction force to suck the dust in the dust box.

The collector may include: a collector body in which dust is collected; a collector cover coupled to a top surface of the collector body and including a dust inlet formed therein into which air containing dust is introduced; dust a separator that is disposed within the collector body and separates dust from the air introduced through the dust inlet; and a collector flow path that is disposed within the collector body and guides the air that has passed through the dust separator to the dust collection motor.

Air can be introduced from above the collector through the dust inlet. Air can flow through the collector flow path in a direction perpendicular to the ground.

Here, the dust separator may include: a screen that filters dust from air introduced through the dust inlet; and a cyclone that separates dust from air that has passed through the screen.

Here, a cyclone can be provided between the screen and the collector flow path.

The flow path through which the air passes within the collector can be optimized.

The collector also includes a transmissive panel disposed on the collector cover, including a surface inclined at a predetermined angle to the ground, and allowing light to pass through the surface.

The area within the collector exposed to UV light can be increased through transmissive panels.

The collector may also include an inlet cover that is rotatably coupled to the collector cover and opens or closes the dust inlet.

The collector may include guide walls provided on both sides of the dust inlet and formed to protrude from the collector cover to guide the airflow that has passed through the dust inlet.

The guide wall may be formed in a direction perpendicular to the rotation axis of the inlet cover.

An imaginary plane obtained by extending the inlet cover passes through the screen with the dust collection motor running.

The air that has passed through the dust inlet through the guide wall and the inlet cover can flow in the direction of the screen.

The collector may include a compression rotation portion rotatably provided to the collector body and moving dust collected in the collector body.

Dust can be compressed by rotating the compression rotating part, and the capacity of collecting dust in the first collector can be increased.

At least a portion of the compression rotation may be provided below the inlet cover.

The compression rotating part may include: a rotating shaft member rotating within the collector body; and a rotating plate connected to the rotating shaft member and moving dust. The upper end of the rotating plate may be disposed farther from the ground than the upper end of the rotating shaft member.

The distance from the rotation axis of the inlet cover to the rotating plate may be greater than the diameter of the inlet cover.

Therefore, the inlet cover and the compression part can be prevented from interfering with each other.

The collector flow path may be formed in a direction perpendicular to the ground.

Vacuum cleaners 100 and 200 may be coupled to the side of vacuum cleaner dock 300. The vacuum cleaner docking station 300 can remove dust from the dust bins 110 and 220 of the vacuum cleaners 100 and 200.

First, the structure of the first vacuum cleaner 200 will be described below with reference to FIGS. 1 to 3 .

The first vacuum cleaner 200 may mean a vacuum cleaner manually operated by a user. For example, the first vacuum cleaner 200 may refer to a handheld vacuum cleaner or a stick vacuum cleaner.

The first vacuum cleaner 200 may be installed on the vacuum cleaner docking station 300 . The first vacuum cleaner 200 may be supported by the vacuum cleaner docking station 300 . The first vacuum cleaner 200 may be coupled to the vacuum cleaner docking station 300 .

Meanwhile, in embodiments of the present invention, the direction of the first vacuum cleaner 200 may be defined based on when the bottom surface (lower surface) of the battery case 230 and the dust box 220 are placed on the ground.

Here, the front may refer to the direction in which the suction part 212 is arranged relative to the suction motor 214, and the rear may refer to the direction in which the handle 216 is arranged relative to the suction motor 214. In addition, based on when the suction part 212 is viewed from the suction motor 214, the direction in which the components are disposed on the right side may be referred to as the right side, and the direction in which the components are disposed on the left side may be referred to as the left side. In addition, in embodiments of the present invention, when the bottom surface (lower surface) of the battery case 230 and the dust box 220 are placed on the ground, the upper side and the lower side may be defined in a direction perpendicular to the ground.

The first vacuum cleaner 200 may include a body 210. The body 210 may include: a body shell 211; a suction part 212; a dust separator 213; a suction motor 214; an exhaust cover 215, a handle 216; and an operating unit 218.

The body shell 211 may form the exterior of the first vacuum cleaner 200 . The body shell 211 may be provided with a space for accommodating the suction motor 214 and a filter (not shown). The body shell 211 may be formed into a shape similar to a cylindrical shape.

The suction part 212 may protrude outward from the body shell 211. For example, the suction part 212 may be formed in a cylindrical shape having an open interior. The suction portion 212 may be coupled to the extension tube 250 . The suction part 212 may be provided with a flow path (hereinafter referred to as a "suction flow path") through which dust-containing air may flow.

The dust separator 213 may be communicated with the suction part 212. The dust separator 213 can separate the dust sucked through the suction part 212 . The space within the dust separator 213 may be connected with the space within the dust box 220 .

For example, the dust separator 213 may include at least one cyclone capable of separating dust through a cyclonic airflow. In addition, the space within the dust separator 213 may be connected to the suction flow path. Therefore, the air and dust sucked through the suction part 212 flow spirally along the inner peripheral surface of the dust separator 213 . Therefore, a cyclonic air flow may occur in the internal space of the dust separator 213 .

The dust separator 213 is connected with the suction part 212 and is configured by applying the principle in which the dust collector utilizes centrifugal force to separate the dust sucked into the body 210 through the suction part 212 .

The dust separator 213 may also contain a second cyclone that separates dust again from the air exhausted by the cyclone. Here, the second cyclone can be arranged within the cyclone, so that the size of the dust collector is minimized. The second cyclone may include a plurality of cyclone bodies arranged in parallel. The air discharged from the cyclone can be distributed into and passed through a plurality of cyclone bodies.

Here, the axis of the cyclone airflow of the second cyclone may also extend in the up-down direction, and the axis of the cyclone airflow of the cyclone and the axis of the cyclone airflow of the second cyclone may be coaxial in the up-down direction. This may be collectively referred to as the axis of the cyclonic airflow of the dust separator 213 .

The suction motor 214 can generate suction force for sucking air. The suction motor 214 can be stored in the body shell 211. The suction motor 214 can generate suction force through rotation. For example, the suction motor 214 may be configured to resemble a cylindrical shape.

The exhaust cover 215 may be provided on one side of the body shell 211 in the axial direction. A filter for filtering air may be housed in the exhaust cover 215 . For example, a HEPA filter may be housed in vent cover 215.

An air outlet for discharging air sucked by the suction force of the suction motor 214 may be formed on the exhaust cover 215 .

The flow guide may be provided on the exhaust cover 215 . The deflector directs the airflow that is exhausted through the air outlet.

Handle 216 can be grasped by a user. A handle 216 may be provided behind the suction motor 214. For example, handle 216 may be formed similar to a cylindrical shape. Alternatively, the handle 216 may be formed in a curved cylindrical shape. The handle 216 may be disposed at a predetermined angle with the body shell 211, the suction motor 214 or the dust separator 213.

The handle 216 may include: a grip portion 216a formed in a cylindrical shape for allowing a user to hold it; and a first extension portion 216b connected to one longitudinal (axial) end of the grip portion 216a and facing the suction motor. 214 extends; and a second extension 216c, which is connected to the other longitudinal (axial) end of the grip 216a and extends toward the dust box 220.

The top surface of the handle 216 may form part of the exterior of the top surface of the first vacuum cleaner 200 . In this way, when the user holds the handle 216, it is possible to prevent a component of the first vacuum cleaner 200 from contacting the user's arm.

The first extension 216b may extend from the grip 216a toward the body housing 211 or the suction motor 214. At least a portion of the first extending portion 216b may extend in a horizontal direction.

The second extension portion 216c may extend from the holding portion toward the dust box 220. At least a portion of the second extending portion 216c may extend in a horizontal direction.

The operating unit 218 may be provided on the handle 216. The operating unit 218 may be provided on an inclined surface formed in the top region of the handle 216 . The user can input an operation command or a stop command of the first vacuum cleaner 200 through the operation unit 218 .

The first vacuum cleaner 200 may include a dust box 220 . The dust box 220 may be communicated with the dust separator 213. The dust box 220 may store dust separated by the dust separator 213.

The dust box 220 may include: a dust box body 221; an exhaust cover 222; a dust box compression rod 223; and a compressor (not shown).

The dust box body 221 may be provided with a space for storing dust separated by the dust separator 213 . For example, the dust box body 221 may be formed into a shape similar to a cylinder.

The lower surface (bottom surface) of the dust box body 221 may be partially open. In addition, the lower surface extension part 221a may be formed on the lower surface (bottom surface) of the dust box body 221. The lower surface extension 221a may be formed to block a portion of the lower surface of the dust box body 221.

Dust bin 220 may include a vent cover 222 . The exhaust cover 222 may be provided on the lower surface of the dust box 220 .

The exhaust cover 222 may be provided to open and close one longitudinal end of the dust box body 221. Specifically, the exhaust cover 222 can selectively open and close the lower portion of the dust box 220 that opens downward.

The exhaust cover 222 may include: a cover body 222a; and a hinge portion 222b. The cover body 222a may be formed to block a part of the lower surface of the dust box body 221. The cover body 222a can rotate downward relative to the hinge portion 222b. The hinge portion 222b may be disposed adjacent to the battery case 230. The torsion spring 222d may be provided on the hinge part 222b. Therefore, when the exhaust cover 222 is separated from the dust box body 221, the cover body 222a can be supported by the elastic force of the torsion spring 222d in a state of being rotated from the dust box body 221 at a greater than a predetermined angle around the hinge portion 222b.

The exhaust cover 222 may be coupled to the dust box 220 through a hook coupling. At the same time, the exhaust cover 222 can be separated from the dust box 220 through the coupling rod 222c. The coupling rod 222c may be provided in front of the dust box 220. Specifically, the coupling rod 222c may be provided on the front outer surface of the dust box 220. When an external force is applied, the coupling rod 222c may elastically deform the hook extending from the cover body 222a, in such a manner that the hook coupling between the cover body 222a and the dust box body 221 is released.

When the exhaust cover 222 is closed, the lower surface of the dust box 220 may be closed (sealed) by the exhaust cover 222 and the lower surface extension 221a.

Dust bin 220 may include dust bin compression lever 223 (see Figure 2). The dust box compression rod 223 may be provided outside the dust box 220 or the dust separator 213 . The dust box compression lever 223 may be provided to move up and down outside the dust box 220 or the dust separator 213 . The dust bin compression rod 223 may be connected to a compressor (not shown). When the dust box compression rod 223 moves downward through external force, the compressor (not shown) can also move downward. In this way, convenience can be provided to users. The compressor (not shown) and the dust box compression rod 223 can return to their original positions through elastic members (not shown). Specifically, when the external force applied to the dust box compression lever 223 is removed, the elastic member can move the dust box compression lever 223 and the compressor upward (not shown).

A compressor (not shown) may be installed in the dust box body 221 . The compressor can move in the internal space of the dust box body 221 . Specifically, the compressor can move up and down inside the dust box body 221 . Therefore, the compressor can compress the dust in the dust box body 221 downward. In addition, when the exhaust cover 222 is separated from the dust box body 221 and the lower part of the dust box 220 is opened, the compressor will move from the upper part to the lower part of the dust box 220, and then remove foreign matter, such as dust remaining in the dust box 220. In this way, residual dust will not remain in the dust box 220, thereby improving the suction power of the vacuum cleaner. In addition, residual dust does not remain in the dust box 220, so that odor generated by the residue can be removed.

The first vacuum cleaner 200 may include a battery case 230 . The battery 240 may be stored in the battery case 230 . Battery housing 230 may be disposed below handle 216 . For example, the battery case 230 may be in the shape of a hexahedron with an open bottom. The rear surface of battery case 230 may be connected to handle 216 .

The battery case 230 may include a receiving portion open downward. The battery 240 can be attached and detached through the receiving portion of the battery case 230 .

The first vacuum cleaner 200 may include a battery 240 .

For example, the battery 240 may be detachably coupled to the first vacuum cleaner 200. Battery 240 may be detachably coupled to battery case 230. For example, the battery 240 may be inserted into the interior of the battery case 230 from below. Such a configuration can improve the portability of the first vacuum cleaner 200.

Different from this, the battery 240 may be integrally provided in the battery case 230 . Here, the bottom surface of the battery 240 is not exposed to the outside.

The battery 240 may power the suction motor 214 of the first vacuum cleaner 200 . The battery 240 may be disposed below the handle 216 . The battery 240 may be provided behind the dust box 220 .

According to this embodiment, when the battery 240 is coupled to the battery case 230, the bottom surface of the battery 240 may be exposed to the outside. Since the battery 240 can be placed on the floor when the first vacuum cleaner 200 is placed on the floor, the battery 240 can be directly separated from the battery case 230 . In addition, since the bottom surface of the battery 240 is exposed to the outside and is in direct contact with the external air of the battery 240, the cooling performance of the battery 240 can be improved.

At the same time, when the battery 240 is integrally fixed on the battery case 230, the structure for loading and unloading the battery 240 and the battery case 230 can be reduced, thereby reducing the overall size of the first vacuum cleaner 200 and reducing the weight of the first vacuum cleaner 200.

The first vacuum cleaner 200 may include an extension tube 250 . The extension tube 250 can be connected with the cleaning module 260 . The extension tube 250 may be communicated with the body 210 . The extension tube 250 may be communicated with the suction part 212 of the body 210. The extension tube 250 may be formed in a long cylindrical shape.

Body 210 may be connected to extension tube 250. The body 210 can be connected to the cleaning module 260 through the extension tube 250 . The main body 210 can generate suction force through the suction motor 214, and can provide the suction force to the cleaning module 260 through the extension tube 250. External dust can be introduced into the body 210 through the cleaning module 260 and the extension tube 250 .

The first vacuum cleaner 200 may include a cleaning module 260 . The cleaning module 260 can be connected with the extension tube 250 . Therefore, external air can be introduced into the body 210 of the first vacuum cleaner 200 via the cleaning module 260 and the extension tube 250 through the suction force generated in the body 210 of the first vacuum cleaner 200 .

The dust in the dust box 220 of the first vacuum cleaner 200 may be collected by the collector 500 of the vacuum cleaner docking station 300 by gravity. At the same time, the dust in the dust box 220 can be collected into the collector 500 of the vacuum cleaner docking station 300 through the suction force of the dust collecting motor 391 provided in the vacuum cleaner docking station 300 . In this way, since the dust in the dust box 220 of the first vacuum cleaner 200 can be removed without the user's separate operation, convenience can be provided to the user. In addition, the user can be saved from the inconvenience of emptying the dust box 220 each time. In addition, dust can be prevented from being scattered during emptying of the dust box 220 .

The first cleaner 200 may be coupled to one side of the housing 310. Specifically, the body 210 of the first vacuum cleaner 200 may be installed on the coupling part 320. More specifically, the dust box 220 and the battery case 230 of the first vacuum cleaner 200 may be coupled to the coupling surface 321 of the coupling part 320. The outer peripheral surface of the dust box body 221 may be coupled to the dust box guide surface 322 . The suction portion 212 may be coupled to the suction portion guide surface 326 of the coupling portion 320 . Through this configuration, the central axis of the dust box 220 can be arranged in a direction parallel to the ground, and the extension tube 250 can be arranged in a direction perpendicular to the ground.

Meanwhile, the second vacuum cleaner 100 will be described below with reference to FIG. 4 .

The vacuum cleaner system 3 may include a second vacuum cleaner 100 . The second vacuum cleaner 100 may refer to a sweeping robot. When the second vacuum cleaner 100 moves on its own in the area to be cleaned, it will absorb foreign objects such as dust on the floor, so that the area to be cleaned can be automatically cleaned. The second vacuum cleaner 100 may include a distance sensor that detects the distance from obstacles such as furniture, office supplies, or walls in the cleaning area, and left and right wheels for moving the sweeping robot. The second vacuum cleaner 100 may be coupled to the vacuum cleaner dock 300 . The dust in the second vacuum cleaner 100 can be collected by the collector 500 through the third flow path 383 .

The second cleaner 100 may be coupled to the lower coupling portion 314 of the cleaner dock 300 . The dust sucked into the dust box 110 of the second vacuum cleaner 100 may be collected to the collector 500 through the third flow path 383 of the second vacuum cleaner 100 .

When the second vacuum cleaner 100 is coupled to the lower coupling portion 314, it may include corresponding terminals (not shown) for charging the battery. In a state where the second cleaner 100 is coupled, the corresponding terminal may be disposed at a position that allows the corresponding terminal to be connected to a charging terminal (not shown) of the lower coupling part 314 . For example, corresponding terminals may be provided in pairs on the bottom surface of the second vacuum cleaner 100 . When the corresponding terminal is electrically connected to the charging terminal (not shown) of the lower coupling part 314, power is supplied to the second vacuum cleaner 100 and the second vacuum cleaner 100 can be charged.

The configuration of the vacuum cleaner docking station 300 according to the embodiment of the present invention will be described below.

Referring to FIG. 4 , a first vacuum cleaner 200 may be coupled to a vacuum cleaner docking station 300 . Specifically, the body of the first vacuum cleaner 200 may be coupled to the side of the vacuum cleaner docking station 300 . More specifically, the dust box 220 of the first vacuum cleaner 200 is coupled to the side of the vacuum cleaner docking station 300 through the side on which the exhaust cover 222 is provided. Therefore, when the exhaust cover 222 is opened, the dust in the dust box 220 can be collected inside the vacuum cleaner docking station 300 and removed.

The vacuum cleaner dock 300 may include a housing 310 . Housing 310 may form the exterior of vacuum cleaner dock 300 . Specifically, the housing 310 may be formed in a columnar shape including at least one outer wall surface. For example, the housing 310 may be formed into a shape similar to a quadrilateral shape.

The housing 310 may have a space formed therein for housing the collector 500 and the dust suction module 390 .

Housing 310 may include: a bottom surface 311; an outer wall surface 312; and a top surface 313.

The bottom surface 311 can support the lower part of the vacuum module 390 in the direction of gravity. That is to say, the bottom surface 311 can support the lower part of the dust collection motor 391 of the dust collection module 390 .

Here, the bottom surface 311 can be placed toward the ground. The bottom surface 311 can be set to be inclined at a predetermined angle with the ground, or can be set to be parallel to the ground. Through such a configuration, the bottom surface can stably support the dust collection motor 391 and balance the overall weight even when the first vacuum cleaner 200 is coupled.

At the same time, the lower coupling portion 314 may be coupled to a lower portion of the bottom surface 311 . The second cleaner 100 may be coupled to the lower coupling part 314. The lower coupling part 314 may be inclined to allow coupling to the bottom surface of the second vacuum cleaner 100 . The lower coupling portion 314 will be described below.

The outer wall surface 312 may refer to a surface formed along the direction of gravity, or may refer to a surface connected to the bottom surface 311 . For example, outer wall surface 312 may refer to a surface vertically connected to bottom surface 311 . In another embodiment, the outer wall surface 312 may be disposed to be inclined at a predetermined angle with the bottom surface 311 .

The outer wall surface 312 may include at least one surface. For example, the outer wall surface 312 may include: a first outer wall surface 312a; a second outer wall surface 312b; a third outer wall surface 312c; and a fourth outer wall surface 312d.

Here, in the present embodiment, the first outer wall surface 312a may be provided in front of the vacuum cleaner docking station 300. Here, the front may refer to a surface of the first vacuum cleaner 200 that is exposed in a state where the first vacuum cleaner 200 is coupled to the vacuum cleaner docking station 300 .

Specifically, the coupling part 320 may be provided on the first outer wall surface 312a, and the dust box 220 of the first vacuum cleaner 200 may be coupled to the coupling part 320. The body 210, the battery case 230 and the dust box 220 of the first vacuum cleaner 200 may also be coupled to the coupling part 320.

Coupling portion 320 may include coupling surface 321 . The coupling surface 321 may be provided on the side surface of the housing 310. For example, the coupling surface 321 may refer to a surface formed in a groove shape that is concave toward the interior of the cleaner docking station 300 from the first outer wall surface 312a. That is, the coupling surface 321 may be formed to have a step difference with respect to the first outer wall surface 312a.

The first cleaner 200 may be coupled to the coupling surface 321. For example, the coupling surface 321 may be in contact with the lower surfaces of the dust box 220 and the battery case 230 of the first vacuum cleaner 200 . Here, the lower surface may refer to a surface facing the ground when the user uses the first vacuum cleaner 200 or places it on the ground.

For example, the angle between coupling surface 321 and the ground may be a right angle. In this way, when the first vacuum cleaner 200 is coupled to the coupling surface 321, the space of the vacuum cleaner docking station 300 can be minimized.

As another example, the coupling surface 321 may be provided to be inclined at a predetermined angle relative to the ground. In this way, when the first vacuum cleaner 200 is coupled to the coupling surface 321, the vacuum cleaner docking station 300 can be stably supported.

A dust through hole 321a may be formed in the coupling surface 321 to allow external air of the housing 310 to flow into the coupling surface 321. The dust through hole 321 a may be formed in a hole shape corresponding to the shape of the dust box 220 so that dust in the dust box 220 flows into the collector 500 . The dust through hole 321a may be formed in a shape corresponding to the exhaust cover 222 of the dust box 220. The dust through hole 321a may be formed to communicate with a flow path 380 to be described below (see FIG. 8 ).

Meanwhile, the protrusion movement hole 322a may be formed on the dust box guide surface 322, and the pushing protrusion 351 to be described below may move in a straight line along the protrusion movement hole 322a (see FIG. 9). In addition, a gear box 355 that accommodates a gear of the lid opening unit 350 described later and the like may be provided below the dust box guide surface 322 in the direction of gravity. Here, the pushing protrusion 351 may be formed between the lower surface of the dust box guide surface 322 and the top surface of the gear box 355, and the pushing protrusion 351 may move through the guide space 322b. In addition, the guide space 322b may communicate with the first flow path 381 through the bypass hole 322c. That is, the protrusion movement hole 322a, the guide space 322b, the bypass hole 322c, and the first flow path 381 may form one flow path. With this configuration, when the dust collection motor 391 operates with the dust box 220 coupled to the coupling portion 320 , dust and the like remaining in the dust box 220 and the dust box guide surface 322 can be removed through the flow path.

The coupling portion 320 may include a guide protrusion 323 . The guide protrusion 323 may be provided on the coupling surface 321 . The guide protrusion 323 may protrude upward from the coupling surface 321 . The two guide protrusions 323 may be provided spaced apart from each other. The distance between the two guide protrusions 323 spaced apart from each other may correspond to the width of the battery case 230 of the first vacuum cleaner 200 .

The coupling side walls 324 may refer to wall surfaces provided on both sides of the coupling surface 321 and may be connected perpendicularly to the coupling surface 321 . Coupling sidewall 324 may be connected to first outer wall surface 312a. Additionally, the coupling sidewall 324 may form a surface connected to the dust bin guide surface 322 . Therefore, the first vacuum cleaner 200 can be stored stably.

The coupling portion 320 may include a coupling sensor. The coupling sensor may detect whether the first vacuum cleaner 200 is coupled to the coupling part 320 .

Coupling sensors may include contact sensors. For example, coupling sensors may include small switches. Here, the coupling sensor may be provided on the guide protrusion 323 . Therefore, when the battery case 230 or the battery 240 of the first vacuum cleaner 200 is coupled between the pair of guide protrusions 323, the coupling sensor will be contacted, and the coupling sensor can detect that the first vacuum cleaner 200 has coupling.

On the other hand, coupled sensors may include contactless sensors. For example, the coupling sensor may include an infrared sensor (IR sensor). Here, the coupling sensor may be disposed on the coupling side wall 324 . Therefore, when the dust box 220 or the main body 210 of the first vacuum cleaner 200 passes through the side wall 324 of the coupling part and touches the coupling surface 321, the coupling sensor detects the presence of the dust box 220 or the main body 210.

In a state where the first vacuum cleaner 200 is coupled to the vacuum cleaner docking station 300, the coupling sensor may face the dust box 220 or the battery case 230 of the first vacuum cleaner 200.

The coupling sensor may be a device for determining not only whether power is to be applied to the battery 240 of the first vacuum cleaner 200 but also whether the first vacuum cleaner 200 is coupled.

Additionally, the vacuum cleaner dock 300 may also include a side door. The side door may be provided in the housing 310. The side door may selectively expose the collector 500 to the outside. In this way, the user can easily detach the collector 500 from the vacuum cleaner docking station 300 .

6 is a view for explaining the fixing unit of the vacuum cleaner docking station according to the embodiment of the present invention.

Referring to FIG. 6 , the vacuum cleaner docking station 300 of the present invention may include a fixing unit 330 . The fixing unit 330 may be provided on the coupling part side wall 324. Furthermore, the fixing unit 330 may be provided on the back side of the coupling surface 321 . The fixing unit 330 may fix the first cleaner 200 coupled to the coupling surface 321. Specifically, the fixing unit 330 may fix the dust box 220 and the battery case 230 of the first vacuum cleaner 200 coupled to the coupling surface 321 .

The fixing unit 330 may include a fixing member 331 for fixing the dust box 220 and the battery case 230 of the first vacuum cleaner 200, and may include a fixing part motor 580 for driving the fixing member 331. In addition, the fixing unit 330 may further include a fixing link 335 for transmitting the power of the fixing motor 580 to the fixing member 331 .

The fixing member 331 may be disposed on the coupling part side wall 324 and may be disposed to perform reciprocating motion on the coupling part side wall 324 to fix the dust box 220 . Specifically, the fixing member 331 may be received in the fixing member inlet and outlet hole 327 .

The fixing members 331 may be respectively provided on both sides of the coupling part 320. For example, the two fixing members 331 may be arranged in pairs symmetrically with respect to the coupling surface 321 .

Fixture motor 580 may provide power to move fixation member 331 .

The fixing part link 335 may convert the rotational force of the fixing part motor 580 into the reciprocating motion of the fixing member 331.

A fixed seal 336 may be provided on the dust box guide surface 322 to seal the dust box 220 when the first vacuum cleaner 200 is coupled to the dust box 220 . With this configuration, when the dust box 220 of the first vacuum cleaner 200 is coupled, the fixed seal 336 can be pressed by the weight of the first vacuum cleaner 200, and the dust box 220 and the dust box guide surface 322 can be sealed.

The fixed seal 336 may be disposed on an imaginary extension line of the fixed member 331 . Through such a structure, when the fixing part motor 580 operates and the fixing member 331 presses the dust box 220, the periphery of the dust box 220 can be sealed at an equal height.

According to this embodiment, the fixed seal 336 may be provided on the dust box guide surface 322 in the form of a curved line corresponding to the arrangement of the lid opening unit 350 described below.

Therefore, when the body 210 of the first vacuum cleaner 200 is disposed on the coupling part 320, the fixing unit 330 can fix the body 210 of the first vacuum cleaner 200. Specifically, when the coupling sensor 325 detects that the body 210 of the first vacuum cleaner 200 is coupled to the coupling part 320 of the vacuum cleaner docking station 300, the coupling part motor 580 moves the fixing member 331, and then fixes the first The main body 210 of the vacuum cleaner 200.

In this way, residual dust will not remain in the dust box 220, thereby improving the suction power of the vacuum cleaner. In addition, residual dust does not remain in the dust box 220, so that odor generated by the residue can be removed.

7 and 8 are views for explaining the relationship between the vacuum cleaner and the door unit in the vacuum cleaner docking station according to the embodiment of the present invention. 7 is a view showing a state in which the door has closed the dust passage hole. FIG. 8 is a view showing a state in which the dust passage hole of the door has been opened.

Referring to FIGS. 7 and 8 , the vacuum cleaner docking station 300 of the present invention may include a door unit 340 . The door unit 340 may be configured to open and close the dust through hole 321a.

The door unit 340 may include: a door 341; a door motor 342; and a door arm 343.

The door 341 may be hinged to the coupling surface 321 and may open and close the dust through hole 321a. Door 341 may include a door body 341a.

The door body 341a may be formed into a shape capable of blocking the dust through hole 321a. For example, the door body 341a may be formed into a dish-like shape.

Based on the state that the door body 341a blocks the dust through hole 321a, the hinge part is provided above the door body 341a, and the arm coupling part 341b is provided below the door body 341a.

The door body 341a may be formed into a shape capable of sealing the dust through hole 321a. For example, the outer surface of the door body 341a exposed to the outside of the vacuum cleaner docking station 300 is formed to have a diameter corresponding to the diameter of the dust through hole 321a, while the inner surface of the door body 341a provided within the vacuum cleaner docking station 300 is formed to have a diameter is larger than the diameter of the dust through hole 321a. Furthermore, a step difference may be formed between the outer surface and the inner surface. Meanwhile, at least one reinforcing rib for connecting the hinge part and the arm coupling part 341b and for strengthening the supporting force of the door body 341a may be formed to protrude from the inner surface.

The hinge portion may be a device that hingely couples the door 341 to the coupling surface 321 . The hinge part may be provided on the upper end of the door body 341a and may be coupled to the coupling surface 321.

The arm coupling portion 341b may be a device rotatably coupled to the door arm 343. The arm coupling part 341b may be provided below the door body 341a and may be rotatably coupled to the door body 341a. The door arm 343 may be rotatably coupled to the arm coupling part 341b.

With this configuration, when the door arm 343 pulls the door body 341a in a state where the door 341 closes the dust through hole 321a, the door body 341a rotatably moves around the hinge portion toward the inside of the cleaner docking station 300, and the dust through hole 321a Can be turned on. On the other hand, when the dust through hole 321a is open, when the door arm 343 pushes the door body 341a, the door body 341a rotates around the hinge toward the outside of the vacuum cleaner docking station 300, and the dust through hole 321a may be blocked.

Meanwhile, in a state where the first vacuum cleaner 200 is coupled to the vacuum cleaner docking station 300 and the exhaust cover 222 is separated from the dust box body 221 , the door 341 may contact the exhaust cover 222 . In addition, according to the rotation of the door 341, the exhaust cover 222 may rotate together with the door 341.

Door motor 342 may provide power to rotate door 341 . Specifically, the door motor 342 may rotate the door arm 343 in a forward or reverse direction. Here, square may refer to the direction in which the door arm 343 pulls the door 341 . Therefore, when the door arm 343 rotates in the forward direction, the dust through hole 321a can be opened. Additionally, reverse direction may refer to the direction in which the door arm 343 pushes the door 341 . Therefore, when the door arm 343 is reversely rotated, the dust through hole 321a may be at least partially closed. Forward can be the opposite of reverse.

The door arm 343 can connect the door 341 and the door motor 342, and can open and close the door 341 by using the power generated by the door motor 342.

For example, the door arm 343 may include: a first door arm 343a; and a second door arm 343b. One end of the first door arm 343a may be coupled to the door motor 342. The first door arm 343a can be rotated by the power of the door motor 342. The other end of the first door arm 343a may be rotatably coupled to the second door arm 343b. The first door arm 343a may transmit the force transmitted from the door motor 342 to the second door arm 343b. One end of the second door arm 343b may be coupled to the first door arm 343a. The other end of the second door arm 343b may be coupled to the door 341. The second door arm 343b can open or close the dust through hole 321a by sliding the door 341.

When the exhaust cover 222 of the first vacuum cleaner 200 is opened, the door unit 340 may be opened together. Furthermore, when the door unit 340 is closed, the exhaust cover 222 of the first cleaner 200 may be closed together with the door unit 340.

When the dust in the dust box 220 of the first vacuum cleaner 200 is removed, the door motor 342 rotates the door 341 to couple the exhaust cover 222 to the dust box body 221 . Specifically, when the door motor 342 rotates the door 341, the door 341 rotates around the hinge part. The door 341 that rotates around the hinge portion can push the exhaust cover 222 toward the dust box body 221 .

The pushing protrusion 351 can perform linear reciprocating motion to press the coupling rod 222c. Specifically, the push protrusion 351 may be coupled to the gearbox 355 and guided in linear motion. The pushing protrusion 351 may be coupled to the cover opening gear 353 and may move together through movement of the cover opening gear 353 .

The lid opening motor 352 may provide power to move the push protrusion 351 . Specifically, the lid opening motor 352 can rotate the motor shaft in a forward or reverse direction. Here, the forward direction may refer to the direction in which the pushing protrusion 351 presses the coupling rod 222c. Furthermore, the reverse direction may refer to the direction in which the pushing protrusion 351 of the pressing coupling lever 222c returns to its original position. Forward can be the opposite of reverse.

The cover opening gear 353 is coupled to the cover opening motor 352 and can move the pushing protrusion 351 by using the power of the cover opening motor 352 . Specifically, the cover opening gear 353 can be stored in the gear box 355 . The driving gear 353a of the cover opening gear 353 may be coupled to the motor shaft of the cover opening motor 352 and may receive power. The driven gear 353b of the cover opening gear 353 may be coupled to the pushing protrusion 351 and may move the pushing protrusion 351. For example, the driven gear 353b may be provided in the form of a rack, may mesh with the driving gear 353a, and may receive power from the driving gear 353a.

Here, the exhaust cover 222 may be provided with a torsion spring 222d. The exhaust cover 222 can rotate by a predetermined angle or a larger angle through the elastic force of the torsion spring 222d, and can be supported at the rotated position of the exhaust cover 222. Therefore, the exhaust cover 222 can be opened and can communicate with the dust through hole 321a and the inside of the dust box 220.

The gearbox 355 may be disposed within the housing 310 and may be disposed below the coupling part 320 in the direction of gravity. The cover opening gear 353 can be stored in the gear box 355.

According to the present invention, the cover opening unit 350 allows the user to open the dust box 220 without separately opening the exhaust cover 222 of the first vacuum cleaner 200, thereby improving convenience.

In addition, since the exhaust cover 222 is opened when the first vacuum cleaner 200 is coupled to the vacuum cleaner docking station 300, dust can be prevented from being scattered.

The first flow path 381 may be provided on the coupling surface 321 . The first flow path 381 may refer to a space formed to allow air to flow between the dust box 220 and the collector 500 of the first vacuum cleaner 200 . For example, the first flow path 381 may be a space surrounded by a structure. For example, the first flow path 381 may be the interior space of a hollow tube.

The first flow path 381 includes: a first area 381a; and a second area 381b. When the first vacuum cleaner 200 is coupled to the vacuum cleaner docking station 300 and the dust through hole 321a is opened, the first area 381a communicates with the internal space of the dust box 220. The second area 381b connects the first area 381a to the collector 500 (see Figure 8).

Therefore, when the dust collecting motor 391 is running, the dust in the collecting box 220 of the first vacuum cleaner 200 can flow to the collector 500 through the first flow path 381 .

The second flow path 382 may connect the collector 500 and the dust collection module 390 . That is, the air separated from the dust may be introduced to the dust collection motor 391 through the second flow path 382 while passing through the collector 500 .

The second flow path 382 may refer to a space formed to allow air to flow between the collector 500 and the dust suction module 390 . The second flow path 382 may be formed surrounded by structures.

In embodiments where collector 500 is first collector 510 , a portion of second flow path 382 may be formed within first collector 510 . This partial area may be referred to as collector flow path 518. Collector flow path 518 may be provided in front of collector body 511 (see Figures 24 and 26).

The third flow path 383 is provided within the housing 310 and connected to the dust box 110 of the second vacuum cleaner 100 .

The third flow path 383 may connect the collector 500 and the dust box 110 of the second vacuum cleaner 100 .

The third flow path 383 may be formed rearwardly from the lower coupling portion 314 and upward after bending. In addition, the upper end of the third flow path 383 may also refer to a flow path formed in a curved shape at a predetermined angle.

That is, when the second vacuum cleaner 100 is coupled to the vacuum cleaner docking station 300 , one end of the third flow path 383 will be connected to the dust box 110 of the second vacuum cleaner 100 . In addition, the other side end of the third flow path 383 may be connected to the first flow path 381 .

Meanwhile, according to this embodiment, the third flow path 383 may be connected to the collector 500 through the flow path switching module 384.

Through this configuration, the third flow path 383 can collect dust stored in the second vacuum cleaner 100 that is disposed closer to the ground than the collector 500 .

Therefore, the dust in the dust box 110 of the second vacuum cleaner 100 can move to the collector 500 through the third flow path 383 .

At the same time, the vacuum cleaner docking station 300 according to the embodiment of the present invention may also include a flow path switching module 384.

The flow path switching module 384 can selectively connect the collector 500 to the dust box 220 of the first vacuum cleaner 200 or the dust box 110 of the second vacuum cleaner 100 .

For example, the flow path switching module 384 can selectively open and close the first flow path 381 and the third flow path 383, thereby selectively connecting the first flow path 381 or the third flow path 383 with the collector 500.

For another example, the connecting flow path formed in the lower part of the flow path switching module 384 allows the flow path switching module 384 to communicate with the collector 500, and the upper part of the flow path switching module 384 can selectively communicate with the first flow path 381 or the second flow path 381. The three flow paths 383 are connected.

Therefore, when only the first vacuum cleaner 200 is coupled to the vacuum cleaner docking station 300, the flow path switching module 384 can connect the first flow path 381 and the collector 500, and can block the connection between the third flow path 383 and the collector 500. .

In addition, when only the second vacuum cleaner 100 is coupled to the vacuum cleaner docking station 300, the flow path switching module 384 can connect the third flow path 383 and the collector 500, and can block the first flow path 381 and the collector 500. connection.

In this way, it is possible to prevent the suction force from being reduced by opening a plurality of flow paths 381 and 383 at the same time.

The vacuum cleaner dock 300 may include a vacuum module 390 .

Referring back to FIG. 10 , the dust collection module 390 may include a dust collection motor 391 . The dust collection motor 391 may be provided below the collector 500 . The dust collection motor 391 may generate suction force in the flow path 380 . In this manner, suction force capable of sucking dust into the dust box 220 of the first vacuum cleaner 200 is provided.

The vacuum module 390 may also include a HEPA filter (not shown). The HEPA filter can be set at the rear end of the dust collection motor 391 (according to the air flow path). Therefore, clean air will flow out to the outside of the housing 310.

Meanwhile, although not shown in FIG. 10 , the fixing unit 330 and the door unit 340 are provided adjacent to the coupling part 320 , which have been described with reference to FIGS. 6 to 8 .

The vacuum cleaner dock 300 may also include a collector 500 .

Figure 11 is a perspective view showing a chamber 360 and a collector 500 shaped to couple with the chamber according to an embodiment of the present invention.

Collector 500 may be detachably coupled to chamber 360. In order to collect the dust sucked in by the dust collecting motor 391 from the inside of the dust box 220, a dust storage space is provided in the collector 500.

Meanwhile, the collector 500 according to the embodiment of the present invention may be a first collector 510 formed in the form of a box having a fixed size dust receiving space.

Since the first collector 510 is in the form of a "box", it is easy to clean the inside of the first collector 510 . Therefore, there is the advantage that the first collector can be used semi-permanently, and only the dust inside needs to be removed. However, some users may find it inconvenient to remove dust and clean the collector because these two tasks must be done separately.

Alternatively, the collector 500 according to the embodiment of the present invention may be the second collector 520 formed in the form of a bag having a dust receiving space of unfixed size.

The second collector 520 is made of a generally breathable material that allows air to flow out but not dust. Since the inside of the second collector 520 cannot be cleaned even when the dust in the second collector 520 is removed, the second collector 520 must be purchased and replaced periodically. However, the second collector 520 has a simple structure, and the second collector 520 can be thrown into the trash can as a whole. Therefore, the second collector 520 is advantageous in terms of user convenience.

Even if any of the two types of collectors 510 and 520 is accommodated in the collector storage space 360a of the chamber 360, the vacuum cleaner docking station 300 according to the embodiment of the present invention can be operated. That is, the two types of collectors 510 and 520 are compatible.

Considering the advantages and disadvantages of the above collectors 510 and 520 and the user's own preferences, the user can choose the collector 510 and 520 to be used.

The benefits of compatibility are not limited to user preference. For example, a user who prefers the first collector 510 can also temporarily use the second collector 520 as an alternative during the process of cleaning and drying the first collector 510, which is another advantage.

Various features of the chamber 360 that allow different types of collectors 510 and 520 to be compatible are described below.

Figure 12 is a cross-sectional view of chamber 360 when viewed from its side, in accordance with an embodiment of the present invention. Figure 13 is an enlarged cross-sectional view of an upper portion of chamber 360 according to an embodiment of the present invention. Figure 14 is a view of chamber 360 viewed from its front, in accordance with an embodiment of the present invention. FIG. 15 is a perspective view showing the internal structure of the chamber 360 according to an embodiment of the present invention. Figure 16 is a cross-sectional view showing compression driver 362 in accordance with an embodiment of the present invention.

First, referring back to FIG. 11 , chamber 360 may include chamber body 361 .

The chamber body 361 forms the exterior of the collector storage space 360a. The collector storage space 360a may have a hexahedral shape.

One side of the chamber body 361 can be open. The open side of the chamber body 361 may be the front. The open side of the chamber body 361 can be closed by the housing cover 370 .

One side of the housing cover 370 may be rotatably coupled to one side of the housing 310 . When the other side of the housing cover 370 rotates away from the housing 310, one side of the chamber body 361 is opened. On the contrary, when the other side of the housing cover 370 is rotated in a direction closer to the housing 310, one side of the chamber body 361 can be closed.

The cross-sectional area of the front end of the collector storage space 360a formed by the chamber body 361 is larger than the cross-sectional area of the rear end thereof.

More specifically, referring to FIG. 12 , an imaginary plane p1 connecting the front upper end and the rear upper end of the chamber body 361 may have a backward and downward oblique angle.

An imaginary plane p2 connecting the front lower end and the rear lower end of the chamber body 361 may have a backward and upward slope.

The upper side of the chamber body 361 is inclined rearward and downward, while the lower side is inclined rearward and upward. The cross-sectional area of the front end of the collector storage space 360a is larger than the cross-sectional area of the rear end.

Through such a structure, there is an advantage that the first collector 510 with a fixed shape can be easily inserted into the collector storage space 360a.

The air inlet 3611 may be provided in the chamber body 361.

The air inlet 3611 passes air introduced through the first flow path 381 . The air inlet 3611 may be provided on the top surface of the chamber body 361. Alternatively, the air inlet 3611 may be provided at the end of a hollow tube integrally connected with the chamber body 361 .

The air inlet 3611 is provided to vertically overlap the dust inlet of the collector 500 as described below. That is, the air and dust that have passed through the first flow path 381 will pass through the air inlet 3611 and the dust inlet in sequence, and be introduced into the dust storage space of the collector 500 .

The air inlet sealing member 367 may be disposed between the air inlet 3611 and the first flow path 381 . The air inlet sealing member 367 seals between the air inlet 3611 and the first flow path 381 to prevent air and dust from leaking into the space outside the chamber body 361 . The air inlet sealing member 367 may be disposed around the perimeter of the air inlet 3611.

As described above, the chamber body 361 has an inclined structure that is inclined substantially downward from the front upper end to the rear upper end. A partial area of the top surface of the chamber body 361 may include a surface that slopes backward and downward at a predetermined angle.

The air inlet 3611 formed on the top of the chamber body 361 may also have an open cross-section that slopes downward from the front to the rear.

The air outlet 3612 may be provided in the chamber body 361.

The air outlet 3612 allows air filtered with dust therein to pass through the collector 500 . The air outlet 3612 may be provided on the lower part of the chamber body 361. The air outlet 3612 may be provided below the installation wall of the filter installation part 365 described below (see Figure 15).

The air outlet 3612 is connected to the dust collection module 390. That is to say, the air passing through the air outlet 3612 can finally be discharged to the outside of the housing through the dust collection module 390 .

Referring to FIGS. 11 and 15 , chamber 360 may contain compression driver 362 .

The compression driver 362 is configured to generate power to rotate the compression rotation part 515 , which compresses the dust collected in the first collector 510 . The compression rotation part 515 will be described below.

The compression driver 362 may be disposed in the lower portion of the chamber body 361 . More specifically, the compression driver 362 may be disposed in the outer lower portion of the chamber body 361 .

The detailed configuration of the compression driver 362 will be described below with reference to FIG. 16 .

Compression driver 362 may include a compression motor 3622. The compression motor 3622 may be provided outside the collector storage space 360a. That is, the compression motor 3622 may be disposed outside and below the chamber body 361.

The compression motor 3622 generates power for rotating the compression rotation part 515 . A motor capable of forward and reverse rotation is provided as a compression motor 3622. In other words, a motor capable of bidirectional rotation is used as the compression motor 3622 .

Therefore, in order to enable the compression motor 3622 to rotate in both forward and reverse directions, a synchronous motor may be used as the compression motor 3622. Such a synchronous motor is configured to perform forward and reverse rotation through the motor itself. When the compression motor 3622 rotates in one direction, if the force applied to the compression motor 3622 is greater than or equal to a set value, the rotation direction of the compression motor 3622 will become The other direction.

Here, the force applied to the compression motor 3622 is the resistance (torque) generated by the rotation plate 5153 described below compressing dust. When the resistance reaches a set value, the rotation direction of the compression motor 3622 is changed.

The technology used for other synchronous motors is well known in the field of motor technology. Therefore, its detailed description will be omitted in this article.

Compression driver 362 may also include drive gear 3621.

The driving gear 3621 is rotated by the power of the compression motor 3622. Therefore, drive gear 3621 may be connected to the motor shaft of compression motor 3622. Drive gear 3621 may be coupled to the top of compression motor 3622.

The driving gear 3621 may be provided outside the collector storage space 360a. That is, the driving gear 3621 may be provided outside the chamber body 361.

Here, part of the bottom surface of the chamber body 361 can protrude upward to form a driving gear receiving portion 3613 (see Figure 15).

A gear through hole 3613a is formed in the lower portion of the chamber body 361 and exposes at least a portion of the driving gear 3621 toward the inside of the collector storage space 360a. More specifically, the gear through hole 3613a may be formed to pass through the side surface of the drive gear receiving portion 3613. The gear teeth 3621c of the driving gear 3621 can be exposed through the gear through hole 3613a (see Figure 15).

At the same time, the driving gear 3621 and the compression motor 3622 are provided outside the collector storage space 360a. Therefore, considering that the collector storage space 360a is periodically opened, there is an effect that the drive gear 3621 and the compression motor 3622 are not contaminated.

The drive gear 3621 may transmit rotational power to the compression rotation part 515 .

The compression rotating part 515 is a concept including one or more rotating components to compress dust collected in the dust storage space of the first collector 510 .

Its detailed structure will be described below. The rotating plate 5153 included in the compression rotating part 515 rotates and collects dust. The rotating plate 5153 may compress dust collected between the fixed plate 5152 and the fixed plate 5152 while rotating to be close to the fixed plate 5152 fixedly arranged on one side of the first collector 510 .

The first collector 510 may include a transmission gear 514 .

The transmission gear 514 may be configured to be coupled to the compression rotation part 515 and may be provided between the compression driver 362 and the compression rotation part 515 to transmit rotational power.

More specifically, the transmission gear 514 may be provided outside and below the first collector 510 . When the first collector 510 is inserted into the collector receiving space 360a, the gear teeth 5142 of the transmission gear 514 may mesh with the gear teeth 3621c of the driving gear 3621 exposed by the gear through hole 3613a.

Therefore, the rotational power generated by the compression motor 3622 can be transmitted to the compression rotation part 515 via the driving gear 3621 and the transmission gear 514 .

At the same time, the drive gear 3621 is accommodated in the drive gear storage portion 3613, and the drive gear storage portion 3613 is formed to protrude upward from the lowermost surface of the collector storage space 360a. Therefore, even if the first collector 510 is only pushed in horizontally, the user can easily make the driving gear 3621 and the transmission gear 514 mesh with each other.

Referring to FIGS. 14 and 15 , the chamber 360 may include a track portion 363 .

The track part 363 may be provided on the upper part of the chamber body 361. More specifically, the track portion 363 may be provided on the inner upper portion of the chamber body 361 .

Track portion 363 is configured to allow at least a portion of second collector 520 to be assembled and coupled thereto. The second collector 520 may slidably move along the track portion 363 . The second collector 520 may be supported while being spaced apart from the bottom surface of the chamber body 361 and suspended from the track portion 363 .

As mentioned above, the second collector 520 is the bag collector 500, and the shape of the dust storage space is variable.

Here, the dust collecting bag 521 contained in the second collector 520 is expanded by the suction driving of the dust collecting motor 391 . Then, the dust may be introduced from the first flow path 381 into the interior of the dust bag 521 through the negative pressure generated by the expansion of the dust bag 521 .

In the embodiment of the present invention, the dust bag 521 as a component of the second collector 520 is made of breathable material. That is, the dust bag 521 is generally made of a material that allows air to flow out but does not allow dust above a certain size to flow out. Therefore, as long as the suction drive of the dust collection motor 391 continues, dust will continue to be sucked into the dust collection bag 521.

When the dust bag 521 is expanded to its maximum state and there is no gap between the lowermost end of the dust bag 521 and the inner bottom surface of the chamber body 361 , the dust suction force will be reduced. Therefore, in order to allow the suction force to be evenly transmitted to the dust bag 521, even if the dust bag 521 is expanded to the maximum, it is best to be separated from the bottom surface of the chamber body 361 by a predetermined distance.

In the embodiment of the present invention, a track portion 363 is provided, the structure of which leaves a space between the bottom surface of the chamber body 361 and the second collector 520 and supports the second collector 520 . Therefore, the first collector 510 and the second collector may be compatible with each other.

The rail portion 363 may include a rail body 3631.

Referring to FIGS. 13 to 15 , the track body 3631 may form a space for the second collector 520 to slide therein. The track body 3631 may be formed to extend from the front to the rear of the chamber body 361. The track body 3631 may be provided on the left and right sides respectively. The track body 3631 may be formed to have a left-right symmetrical structure.

The track body 3631 is open toward the center of the chamber body 361 and may be arranged in a shape similar to a "U" shape rotated 90 degrees. From another perspective, based on the rail body 3631 provided on the left side, the rail body 3631 may be provided in a shape similar to a quadrilateral with one open side.

However, the above shape of the track body 3631 is an example, and the shape of the track body 3631 can be changed in response to a suitable structure that can support the second collector 520 above the chamber body 361.

Like the top surface of the chamber body 361, the top surface of the track body 3631 disposed on the top surface of the chamber body 361 may be formed to be inclined. Different from this, the bottom surface of the track body 3631 may be formed parallel to the ground. (See Figure 13)

The detailed structure of the rail portion 363 will be further described below with reference to FIGS. 17 and 18 .

FIG. 17 is an enlarged view of part A of FIG. 15 . FIG. 18 is a cross-sectional view taken along line CC′ of FIG. 17 .

Referring to FIGS. 17 and 18 and 15 , the rail portion 363 may further include an interference protrusion 3632 .

The interference protrusion 3632 may be provided in a first position (position 1), which interferes with the housing cover 370 in front of the track body 3631.

More specifically, the first position may refer to a position that prevents the housing cover 370 from closing the open side of the chamber body 361 .

From another perspective, the first position may refer to shielding the first collector 510 or the second collector 520 when the first collector 510 or the second collector 520 is inserted into the collector receiving space 360a. The location where the partial component is inserted into the process path.

Here, in the case of the first collector 510, the above-mentioned partial component in which the insertion process path is shielded may be an outer flat plate 522 described later (see FIG. 32). In the case of the second collector 520, some of the above-mentioned components may be ribs 5161c and formed to protrude from the collector cover 516 (see Figure 23).

The interference protrusion 3632 can be moved to a second position that avoids interference with the housing cover 370 by contacting the first collector 510 (specifically, the outer plate 522) or the second collector 520 (specifically, the rib 5161c). (Position 2).

At the same time, the cover protrusion 371 may protrude from the housing cover 370 .

When the housing cover 370 rotates to close the open side of the chamber body 361, the cover protrusion 371 may be disposed at a position where the housing cover 370 contacts the aforementioned interference protrusion 3632 (FIG. 15). That is, interference between the interference protrusion 3632 and the housing cover 370 means that the interference protrusion 3632 contacts the cover protrusion 371 .

Track portion 363 may also include tab guides 3633.

Continuing with reference to FIGS. 17 and 18 , tab guide 3633 may be coupled to interference tab 3632 . Tab guide 3633 may guide movement of interference tab 3632.

More specifically, tab guide 3633 has a space formed therein to receive interfering tab 3632. The catching protrusion 3662 may be formed in the space and may be caught by a hook 3632a formed at an end of the interference protrusion 3632 and coupled to the hook 3632a.

The interference protrusion 3632 may be disposed in the first position with the hook 3632a in contact with the clamping protrusion 3662. As interference tab 3632 moves from the first position to the second position, contact between hook 3632a and catch tab 3662 may be released. (See Figure 19)

Track portion 363 may also include restoration members 3634.

Referring to FIG. 18 , the recovery member 3634 may be coupled to the space formed within the interference protrusion 3632 . The direction in which the interference protrusion 3632 moves from the first position to the second position is defined as the first movement direction "md1", and the direction opposite to the first movement direction is defined as the second movement direction "md2". The restoration member 3634 may provide the interference protrusion 3632 with an elastic force toward the second moving direction, and the interference protrusion 3632 may move along the second movement direction until the hook 3632a and the clamping protrusion 3662 contact the restoration member 3634.

Referring to FIG. 19 , the operation of the interference protrusion 3632 when the collection body 500 is inserted and not inserted into the collector receiving space 360 a will be described below.

19 is a view illustrating the movement of the interference protrusion 3632 and the positional relationship with the interference protrusion and the housing cover 370 according to an embodiment of the present invention.

The figure on the left side of FIG. 19 shows the interference protrusion 3632 in the first position, and the cover protrusion 371 and the interference protrusion 3632 are in contact with each other. Here, when the cover protrusion 371 contacts the interference protrusion 3632, a direction in which a force is applied to the interference protrusion 3632 and a direction in which the interference protrusion 3632 moves from the first position to the second position may form a predetermined angle.

There is no component in the direction of the force that interferes with the movement of protrusion 3632 from the first position to the second position. Therefore, the interference protrusion 3632 cannot move through the pressing force of the cover protrusion 371 , and the interference protrusion 3632 prevents the housing cover 370 from rotating again. Therefore, the chamber body 361 cannot be closed.

The figure on the right side of FIG. 19 shows that the interference protrusion 3632 is in the second position, and the cover protrusion 371 and the interference protrusion 3632 are not in contact. The housing cover 370 can rotate and move until the housing cover 370 completely closes the open side of the chamber body 361 .

Here, the first collector 510 or the second collector 520 will move the interference protrusion 3632 from the first position to the second position. When the first collector 510 or the second collector 520 is inserted into the collector receiving space 360a, part of the first collector 510 or the second collector 520 may push the interference protrusion 3632 to the second position.

The interference protrusion 3632 may be provided with a slope 3632c that contacts a portion of the collector 500.

Referring to FIG. 15 , the chamber 360 may also include a filter mounting portion 365 .

The filter mounting part 365 may be provided in the lower part of the chamber body 361. The filter installation part 365 may refer to a filter installation space and an installation wall. The pre-filter module 470 that filters the air that has passed through the collector 500 is attachably and detachably coupled to the filter installation space. The mounting wall surrounds the filter mounting space.

Here, the above-mentioned air outlet 3612 is formed at the lower end of the mounting wall. In another figure, the air outlet 3612 is formed at the lower end of the filter installation space.

If the pre-filter module 470 is coupled to the filter mounting part 365, the air leaving the collector 500 and flowing to the air outlet 3612 will pass through the pre-filter module 470 and then move to the dust suction module 390 via the air outlet 3612.

If the pre-filter module 470 is not coupled to the filter mounting part 365, the air that has left the collector 500 will flow through the air outlet 3612 as it is and move to the dust suction module 390.

Figure 20 is an exploded and unfolded view showing the pre-filtration module 470 according to an embodiment of the present invention.

Referring to Figure 20, the pre-filtration module 470 may include: filter housings 471 and 472; and filters 473 and 474.

The filter housings 471 and 472 may include: an upper housing 471; and a lower housing 472, and the upper housing 471 and the lower housing 472 may be coupled through a hinge. When the upper shell 471 and the lower shell 472 rotate around the hinge, the space inside the shell can be opened and closed.

The air inlet 4711 is formed on the upper case 471.

The air inlet 4711 may be formed on the top surface of the upper case 471 in such a manner that its shape corresponds to the shape of the collector flow path 518 of the first collector 510 which will be described below. Air that has exited the collector flow path 518 of the first collector 510 may be introduced into the filter housings 471 and 472 through the air inlet 4711 . The air that has left the dust bag 521 of the second collector 520 may be introduced into the filter housings 471 and 472 through the air inlet 4711.

The air outlet 4721 is formed on the lower shell 472.

The air outlet 4721 may be formed by a plurality of holes passing through the bottom surface of the lower shell 472 . The air outlets 4721 can be distributed over the entire area of the bottom surface of the lower shell 472 so that air can pass through the filter evenly.

At least one of the filters 473 and 474 may be housed in an internal space formed by the upper case 471 and the lower case 472 . Filters 473 and 474 may include a first filter 473 made of sponge material. Filters 473 and 474 may include a second filter 474 made of nonwoven fabric.

The pressing protrusion 4712 may be formed to protrude from one side of the filter cases 471 and 472.

When the pre-filter module 470 is installed on the filter mounting part 365, the pressing protrusion 4712 is configured to press the filter detection protrusion 366 described below. The pressing protrusion 4712 may be formed in the form of a rib protruding from one surface of the upper case 471 or the lower case 472 (see FIG. 22 ).

Referring to FIG. 15 , the chamber 360 may also include a filter detection protrusion 366 .

A filter detection protrusion 366 may be provided in a lower portion of the chamber body 361 . More specifically, the filter detection protrusion 366 may be provided adjacent to the mounting wall of the filter mounting portion 365 .

In a state where the pre-filter module 470 is not coupled to the filter mounting part 365, one side of the filter detection protruding part 366 may remain protruding toward the collector storage space 360a.

Therefore, although not shown in the figure, a pressing device for applying force in a direction in which one side protrudes may be coupled to the filter detection protrusion 366 . For example, the pressing device may be an elastic body, such as a spring.

In this case, when one side of the filter detection protrusion 366 protrudes toward the collector storage space 360a, a rear side of the first collector 510 will interfere with the filter detection protrusion 366, so that the second collector 510 cannot be completely connected to the filter detection protrusion 366. A collector 510 is inserted into the collector storage space 360a.

In contrast, since the second collector 520 remains spaced apart from the lower end of the chamber body 361 even when the dust bag 521 is fully expanded, the second collector 520 will not be detected by the filter protrusion 366 when inserted. interference.

With this configuration, the user must install the pre-filter module 470 on the filter mounting portion 365 in order to use the first collector 510 . When the user detaches the pre-filter module 470 and inserts the first collector 510 into the chamber body 361 while forgetting to detach the pre-filter module 470 , the first collector 510 is stuck by the filter detection protrusion 366 and cannot be used. will be fully inserted. After installing the pre-filtration module 470 on the filter mounting portion 365, the user can insert the first collector 510 into the chamber body 361 again.

At the same time, in a state where the pre-filter module 470 is coupled to the filter mounting part 365, one side of the filter detection protrusion 366 may be pressed by the pre-filter module 470. In this case, the filter detection protrusion 366 may be moved in a direction to avoid interference with the first collector 510 .

FIG. 21 is an enlarged view showing part B of FIG. 15 , and is a view for explaining the movement of the filter detection protrusion 366 depending on whether the pre-filter module 470 is installed. FIG. 22 is a cross-sectional view taken along line DD′ of FIG. 21 .

Referring to FIGS. 21 and 22 , the filter detection protrusion 366 may include: a protrusion body 3661 ; and a clamping protrusion 3662 protruding from the outer surface of the protrusion body 3661 . Here, a space for disposing the above-mentioned pressing device (not shown) may be formed in the protrusion body 3661 .

The left picture of FIG. 21 shows a state in which the pre-filtration module 470 is not installed on the filter mounting part 365. One side of the filter detection protrusion 366 remains protruding toward the collector storage space 360a.

The right picture of FIG. 21 shows the state in which the pre-filtration module 470 is installed on the filter mounting part 365. Referring to FIG. 22 , the clamping protrusion 3662 of the filter detection protrusion 366 is pressed by the pressing protrusion 4712 .

Here, as in the embodiment of FIG. 22 , the pressing protrusion 4712 may be formed to protrude from one surface of the upper case 471 . When the pre-filter module 470 is installed on the filter installation part 365, the pressing protrusion 4712 can contact the clamping protrusion 3662, can invade the collector storage space 360a, and then press the filter detection protrusion 366 downward. protruding side.

Therefore, the first collector 510 can be completely inserted into the chamber body 361 without interference.

On the other hand, the necessity of the above-mentioned filter detection protrusion 366 is related to the difference between the dust separation device of the first collector 510 and the dust separation device of the second collector 520 .

The screen 5121 and the cyclone 513 can serve as dust separation devices of the first collector 510 .

The dust bag 521 made of breathable material can serve as a dust separation device of the second collector 520 .

In the case of the second collector 520 , dust having a certain size or larger cannot pass through the dust bag 521 due to the structure. Since the dust bag 521 can perform the function of a pre-filter, the pre-filter module 470 can be installed according to the user's choice and is not necessary.

However, in the case of the first collector 510, although fine dust can generally be separated through the dust collection operation of the cyclone 513, it is structurally impossible to completely filter the fine dust, just like the dust bag of the first collector 510 521 is the same.

Therefore, in order to prevent fine dust from entering the dust collection motor 391 , the pre-filter module 470 must be disposed in the path through which the air that has passed through the first dust collector 510 flows into the dust collection motor 391 .

According to an embodiment of the present invention, using the first collector 510 has the effect of reminding the user that the pre-filter module 470 is not equipped.

In addition, according to embodiments of the present invention, the second collector 520 can be used regardless of whether the pre-filtration module 470 is installed, thereby reducing the filter purchase cost according to the user's choice.

Referring to Figure 13, the chamber 360 may also include a sterilization module mounting portion 364.

The sterilization module mounting part 364 can be disposed on the chamber body 361 . The disinfection module mounting portion 364 may be disposed to be spaced apart from the air inlet 3611. The sterilization module installation part 364 may include: a sterilization module installation space; and an installation wall. The sterilization module mounting portion is formed by bending a portion of the top surface of the chamber body 361 upward. The installation wall surrounds the installation space.

The sterilization module mounting part 364 may be equipped with a sterilization module 450 configured to irradiate ultraviolet light to the collector storage space 360a.

The disinfection module 450 is configured to disinfect dust collected by the collector 500 . The disinfection module 450 may include: a light source; and a protective panel. The light source emits disinfecting light. The protective panel is arranged under the light source and protects the light source.

In a possible embodiment, the light source and the protective panel may be installed on the disinfection module mounting part 364 in a form of being housed in a separately provided housing. Alternatively, in a possible embodiment, the light source and the protective panel can be installed in the sterilization module installation space in a form that is directly stored in the sterilization module installation space.

In this way, as long as the disinfection module 450 and the disinfection module installation part 364 are configured and coupled, the light source of the disinfection module 450 can emit disinfection light toward the collector storage space 360a, and the arrangement is not limited to any one. Example.

Here, the light source may comprise at least one light-emitting diode (LED) capable of emitting disinfecting light with germicidal capabilities. The disinfecting light emitted by the light source may have a wavelength that varies depending on the type of light emitting diode.

For example, the light source may be a light emitting diode that emits ultraviolet light in the UV-C wavelength range. UV light is divided into UV-A (315nm to 400nm), UV-B (280nm to 315nm) and UV-C (200nm to 280nm) according to wavelength. Among them, ultraviolet rays in the UV-C region can destroy the DNA double helix and inhibit the growth of microorganisms.

Or, as another example, the light source may be a light emitting diode emitting visible light with a wavelength of 405 nm. Blue light with a wavelength of 405nm has a wavelength in the border region between visible light and ultraviolet light and has been determined to have germicidal capabilities.

The protective panel may be disposed at a predetermined distance from the light source to prevent damage to the light source. Here, the protective panel can be made of a material that maximizes the transmittance of the light source. For example, protective panels can be made of quartz. Quartz is known to not interfere with the transmission of ultraviolet light in the UV-C region.

In the embodiment of the present invention, a sterilization module 450 and a sterilization module mounting part 364 are provided. Therefore, even when the dust sucked from the dust box 220 of the first vacuum cleaner 200 is stored in the collector 500 for a long time, there is an advantage that the cleaner docking station 300 can be hygienically managed.

In addition, in the embodiment of the present invention, since the sterilization module mounting part 364 is disposed in the chamber 360, the user can use the sterilization function no matter which type of collector 500 is selected.

The detailed structure of the first collector 510 will be described below.

Figure 23 is a perspective view of the first collector 510 according to an embodiment of the present invention. 24 is a view showing components related to the disassembly and deployment of the first collector 510 according to an embodiment of the present invention. FIG. 25 is a view showing the dust separation process of the cyclone 513 according to the embodiment of the present invention. Fig. 26 is a cross-sectional view taken along line XX' of Fig. 23.

Referring to Figures 23 to 26, the first collector 510 may include: a collector body 511; and a collector inner wall 512.

The collector body 511 forms the exterior of the collector storage space 360a. In a possible embodiment, the collector body 511 may generally have a hexahedral shape. In another possible embodiment, the collector body 511 may generally have a cylindrical shape.

Dust may be collected in the internal space of the collector body 511.

The first collector 510 may also include a collector cover 516 disposed to cover the open top of the collector body 511 . That is, the collector cover 516 may be coupled to the top of the collector body 511 and may form a space for allowing air to flow within the collector body 511 and for storage by covering the open top of the collector body 511 dusty space.

The collector cover 516 may have a shape corresponding to the shape of the rail portion 363 .

More specifically, the collector cover 516 may include: a first cover portion 5161; and a second cover portion 5162.

The top surface of the first cover part 5161 may be formed to incline backward and downward. Therefore, the height of the rear upper part of the first collector 510 may be lower, and the height of the front upper part may be higher.

At the same time, as mentioned above, in the collector storage space 360a formed by the chamber body 361, the cross-sectional area of the front end may be larger than the cross-sectional area of the rear end.

That is, the height of the rear portion of the first collector 510 initially inserted into the collector storage space 360a is relatively low, while the height of the front end of the collector storage space 360a is relatively high, and the front end is the entrance into which the first collector 510 is inserted. Therefore, the first collector 510 can be easily inserted into the collector storage space 360a.

The second cover part 5162 may be coupled to the left and right sides of the first cover part 5161. The second cover part 5162 may be formed to extend in the horizontal direction from the side bottom end of the first cover part 5161. That is to say, the top surface of the first cover part 5161 and the top surface of the second cover part 5162 may form a step difference, so that the top surface of the first cover part 5161 is at a higher position.

In a state where the first collector 510 is inserted into the chamber body 361 , the side of the first cover 5161 is disposed to face the side of the rail body 3631 . More specifically, the left and right side surfaces of the first cover part 5161 are disposed to face the side surfaces of the left and right rail body 3631 . Viewed from another angle, the first cover 5161 is provided between the left and right track bodies 3631 (see Figure 29).

In a state where the first collector 510 is inserted into the chamber body 361 , the top surface of the second cover part 5162 is disposed to face the bottom surface of the track body 3631 .

The transmissive panel 5161b may be provided on the top surface of the first cover part 5161.

When the first collector 510 is inserted into the chamber body 361, the transmission panel 5161b is disposed at a position corresponding to the position where the sterilization module 450 is disposed. That is, when the first collector 510 is inserted into the chamber body 361, the sterilization module 450 and the transmission panel 5161b are disposed to face each other.

Transmissive panel 5161b is made of a material that allows light to pass therethrough. Specifically, the transmissive panel 5161b is made of a material that allows the disinfection light energy emitted from the disinfection module 450 to pass toward the interior of the collector body 511 . For example, the transmissive panel 5161b may be made of polymethylmethacrylate (PMMA) material.

The transmissive panel 5161b may include a surface 5161ba that is inclined at a predetermined angle to the ground. That is, the transmissive panel 5161b may include an inclined surface 5161ba forming a predetermined angle with the top surface of the first cover 5161. For example, as shown in FIG. 30 , the inclined surface 5161ba may be formed to be inclined downward in the first cover part 5161 .

Through this configuration, the disinfection light (ultraviolet light) irradiated from the disinfection module 450 can change its refraction angle while passing through the inclined surface 5161ba of the transmission panel 5161b. Therefore, the sterilizing light irradiation area in the collector 500 can be expanded.

A dust inlet 5161a through which dust and air introduced from the first flow path 381 pass may be formed on the top surface of the first cover part 5161. For example, dust inlet 5161a may have a circular shape. The first flow path 381 is connected to the top side of the dust inlet 5161a. Therefore, the air sucked in by the suction force of the dust collection motor 391 can be introduced into the collector body 511 . The dust inlet 5161a may be provided in an upper portion of the first dust storage space S1 described below.

With this configuration, air can be introduced from above the collector 500 through the dust inlet 5161a. That is, the dust inlet 5161a is connected with the first flow path 381, and when the dust collection motor 391 is running, air can be introduced into the collector 500 in a direction perpendicular to the ground. Therefore, according to the embodiment of the present invention, there is an effect of minimizing flow path loss.

In addition, the dust inlet 5161a is connected to the third flow path 383, and when the dust collection motor 391 is operating, the dust stored in the dust box 110 of the second vacuum cleaner 100 provided below the dust collection motor 391 can be introduced from above. Here, the dust inlet 5161a may communicate with the third flow path 383 through the first flow path 381. In addition, according to this embodiment, the first flow path 381 or the third flow path 383 can also be selectively connected through the flow path switching module 384 .

This arrangement has the effect of preventing dust contained in the air from flowing back compared to the case where the dust inlet is formed on the side of the collector.

In addition, even if the collector 500 is connected to the dust box 220 of the first vacuum cleaner 200 or the dust box 110 of the second vacuum cleaner 100, the suction force of the dust collection motor 391 can be fully transferred by combining the air introduction space to avoid loss.

Based on the state of the first collector 510 being inserted into the chamber body 361, the dust inlet 5161a and the air inlet 3611 of the chamber body 361 may be positioned to face each other.

Here, since the dust inlet 5161a is formed in the top surface of the first cover 5161, which is formed to be inclined rearward and downward, the cross section of the dust inlet 5161a is also inclined rearward and downward. The cross-section of the air inlet 3611, which has been described above, also slopes rearward and downward. Since the inclination directions of the air inlet 3611 and the dust inlet 5161a are the same, they can be sealed without separation.

The first collector 510 may include an inlet cover 5163. Inlet cover 5163 may be rotatably coupled to collector cover 516 . Specifically, the access cover 5163 may be hinged to the first cover portion 5161 .

The inlet cover 5163 can open or close the dust inlet 5161a. Inlet cover 5163 is configured to close or open dust inlet 5161a. The inlet cover 5163 may be provided in a shape corresponding to the shape of the dust inlet 5161a, and may be coupled to one side of the dust inlet 5161a.

The inlet cover 5163 can be opened by the suction force of the dust collection motor 391. That is to say, the inlet cover 5163 can be opened toward the internal space of the collector body 511 (specifically, the first dust storage space S1).

Here, when the dust collection motor 391 is running, the virtual plane P obtained by extending the inlet cover 5163 can pass through the screen 5121 (see FIG. 30 ).

Through this configuration, the air that has passed through the dust inlet 5161a can flow downward along the surface of the inlet cover 5163 toward the screen 5121 in an oblique manner. Therefore, the air flow direction that has passed through the dust inlet 5161a can be directed toward the screen 5121.

When the dust collection motor 391 is not driven, the inlet cover 5163 can keep the dust inlet 5161a closed. When the dust collection motor 391 starts to operate, the inlet cover 5163 can open the dust inlet 5161a.

Therefore, the inlet cover 5163 may be provided with means for exerting a restoring force in the direction of closing the dust inlet 5161a. For example, the restoring force applying device may be an elastic member such as an x-torsion spring.

With this configuration, the inlet cover 5163 keeps the dust inlet 5161a closed when no suction force is applied. In addition, odors, contaminants, bacteria, and the like that may be present in the first collector 510 can be prevented from spreading to the first flow path 381 .

The rib 5161c may be formed to protrude from the outer surface of the first cover part 5161.

Here, the outer surface may refer to a surface connecting the top surface of the first cover part 5161 and the top surface of the second cover part 5162.

The rib 5161c may be formed in front of the outer surface of the first cover part 5161. The rib 5161c may protrude in a direction parallel to the top surface of the second cover 5162. When the first collector 510 is inserted into the chamber body 361, the ribs 5161c may be inserted into the sliding space of the track part 363 (specifically, the track body 3631).

When the first collector 510 is inserted into the chamber body 361, the rib 5161c may push the interference protrusion 3632 disposed in the first position to the second position (see Figure 19).

The first collector 510 includes a guide wall 5161d. The guide wall 5161d may be formed to protrude from the lower surface of the collector cover 516. Specifically, the guide wall 5161d may be formed to protrude from the lower surface of the first cover part 5161. Here, a pair of guide walls 5161d may be formed to face each other with the dust inlet 5161a located therebetween.

Therefore, the guide walls 5161d may be provided on both sides of the dust inlet 5161a to prevent air introduced through the dust inlet 5161a from flowing in the direction in which the guide walls 5161d are formed.

At least a portion of the guide wall 5161d may be formed in a direction perpendicular to the rotation axis Y of the inlet cover 5163 (see FIG. 31 ).

Therefore, when the inlet cover 5163 is opened with the rotation axis of the inlet cover 5163 as the rotation center, the airflow introduced through the dust inlet 5161a will be restricted in three directions by the pair of guide walls 5161d and the inlet cover 5163, and the airflow can be directed to the remaining direction.

Therefore, the direction of the airflow introduced through the dust inlet 5161a can be directed toward the direction of the screen 5121 by the guide wall 5161d and the inlet cover 5163.

On the other hand, as shown in FIG. 31, according to an embodiment, a part of the guide wall 5161d may be formed in a curved shape toward the rotation axis of the inlet cover 5163. Through such a configuration, the space between the guide wall 5161d and the open inlet cover 5163 can be reduced, and the efficiency of guiding air can be improved.

Therefore, according to the present invention, the guide wall 5161d and the inlet cover 5163 guide the flow path of the air introduced into the collector 500 to be as short as possible, thereby optimizing the air flow efficiency.

The first collector 510 may also include a bottom cover 517 disposed to cover the open bottom side of the first collector 510 body.

The collector hinge 519 may be provided on one side of the edge of the bottom cover 517 . When the bottom cover 517 rotates around the collector hinge 519, the interior of the collector body 511 can be opened. Therefore, the user can remove the dust collected in the collector body 511 by discharging the dust to the outside.

The handle 5111b may be provided on the front (or front side) of the collector body 511 . The handle 5111b is configured to be held by a user such that the first collector 510 can be pulled outside the chamber body 361 . The user can easily pull the first collector 510 out of the chamber body 361 by holding the handle 5111b and pulling the first collector 510 forward.

Finger grooves 5111a may be provided in the collector body 511 so that the user can easily grasp the handle 5111b. Finger grooves 5111a are formed to fit a user's fingers therein. The finger groove 5111a is formed in a shape in which the collector body 511 is recessed toward the internal space of the first collector 510 .

With this configuration, the handle 5111b does not protrude excessively outside the collector body 511. That is, this structure contributes to miniaturization of the vacuum cleaner docking station 300.

The inner wall 512 of the collector may be disposed in the dust storage space of the collector body 511 . The inner wall 512 of the collector can divide the dust storage space of the collector body 511 into two separate spaces. The inner wall 512 of the collector may be arranged in a direction perpendicular to the ground. Through this configuration, the collector inner wall 512 can be separated and coupled in the vertical direction relative to the collector body 511, so the user can easily separate and clean the collector inner wall 512.

The screen 5121 can be disposed on the inner wall 512 of the collector. For example, the screen 5121 may form part of the inner wall 512 of the collector. That is, when the air flows from one side of the divided dust receiving space to the other side, the air can pass through the screen 5121.

The screen 5121 can filter dust from the air introduced through the dust inlet 5161a. That is, the screen 5121 may be a device capable of separating dust from the air introduced into the first collector 510 .

Therefore, below, the screen 5121 and the cyclone 513 to be described later may be referred to as dust separators 5121 and 513.

Dust separators 5121 and 513 may be provided within the collector body 511 and may separate dust from air introduced through the dust inlet 5161a.

At the same time, the storage space in the first collector 510 is divided into a first dust storage space S1 and a second dust storage space S2 by the collector inner wall 512 .

The compression rotation part 515 may be provided in the first dust storage space S1. The cyclone 513 may be provided in the second dust storage space S2. The air sucked in from the outside through the first flow path 381 will first flow into the first dust storage space S1, and then flow into the second dust storage space S2 through the screen 5121.

In this way, larger dust can be filtered out by the screen 5121. The filtered large dust will be collected and stored in the lower part of the first dust storage space S1.

In this embodiment, the dust separator includes a cyclone 513 .

A plurality of cyclones 513 can be provided. For example, at least two conical or cylindrical cyclone bodies may be provided.

Here, the cyclone 513 may be disposed in a direction perpendicular to the ground. Through this configuration, the cyclone 513 can be separated and coupled in the vertical direction relative to the collector body 511, so the user can easily separate and clean the cyclone.

The cyclone 513 can separate dust from the air that has passed through the screen 5121.

Here, the cyclone 513 may be disposed between the screen 5121 and the collector flow path 518 .

Through this arrangement, the path taken by the air flowing within the collector 500 can be optimized.

Referring to Figure 25, each cyclone body includes an inlet body 5131 into which air that has passed through the screen 5121 is introduced. Each cyclone body also includes an outlet body 5132 connected to the collector flow path 518 .

Collector flow path 518 may be located within collector body 511 and may direct air that has passed through dust separators 5121 and 513 to dust collection motor 391 .

Furthermore, the collector flow path 518 is connected to the dust collection motor 391 side and constitutes a part of the second flow path 382 as described above.

Collector flow path 518 may be formed in a direction perpendicular to the ground. Therefore, air may flow through the collector flow path 518 in a direction perpendicular to the ground.

Air is drawn in from the outlet body 5132 through suction force applied to the collector flow path 518, and a cyclonic airflow is generated in the inlet body 5131. Through this cyclonic airflow, fine dust can be filtered out from the air that has passed through the screen 5121.

The first collector 510 may include a compression rotation 515 .

The compression rotation part 515 is configured to compress dust collected in the first collector 510 .

Referring to FIGS. 24 and 26 , the compression rotation part 515 is provided in the dust storage space of the collector body 511 . More specifically, the compression rotation part 515 is provided in the first dust storage space S1 of the collector body 511 .

The compression rotation part 515 is movably provided in the collector body 511 . The compression rotation part 515 can move in one direction to compress the dust collected in the first dust storage space S1. In an embodiment of the present invention, the compression rotation part 515 may be rotatably disposed in the first dust storage space S1.

At least a portion of the compression rotation portion 515 may be disposed below the inlet cover 5163 . For example, the rotation axis member 5151 may be provided below the inlet cover 5163.

The compression rotation part 515 is rotatable around an axis provided in the longitudinal direction within the collector body 511 (first dust storage space S1 ). More specifically, the compression rotation part 515 may include: a rotation shaft member 5151; a fixed plate 5152; and a rotation plate 5153.

The rotation shaft member 5151 may be provided within the collector body 511, that is, in the first dust storage space S1 along the up-and-down direction. The rotation shaft member 5151 can rotate by receiving power from the compression motor 3622 described above. The central axis of the rotation shaft member 5151 may be coaxial with the central axis of the first dust storage space S1.

Through this configuration, the compression rotation part 515 can be separated and coupled in the vertical direction relative to the collector body 511, so the user can easily separate and clean the compression rotation part.

The lower end of the rotation shaft member 5151 may be supported by being connected to the bottom surface of the first dust storage space S1. The upper end of the rotating shaft member 5151 may be separated from the dust inlet 5161a by a predetermined distance so as not to interfere with the opening of the inlet cover 5163 (see Figure 30).

The fixing plate 5152 may be fixedly disposed on one side of the first collector 510 . More specifically, the fixing plate 5152 may be disposed in the first dust storage space S1 in the up-and-down direction, and may be fixedly coupled to one side of the inner peripheral surface of the collector body 511 forming the first dust storage space S1. The fixed plate 5152 may be in the form of a quadrilateral flat plate. The fixed plate 5152 can be arranged opposite to the screen 5121.

The fixed plate 5152 may completely or partially shield the first dust storage space S1, thereby compressing the dust pushed and moved due to the rotation of the rotating plate 5153 together with the rotating plate 5153.

The rotating plate 5153 may be provided to be connected to the outer peripheral surface of the rotating shaft member 5151 and may rotate together with the rotating shaft member 5151. More specifically, the rotating plate 5153 may be provided between the inner peripheral surface of the collector body 511 constituting the first dust storage space S1 and the outer peripheral surface of the rotation shaft member 5151, and may be rotatable.

The shape of the rotating plate 5153 is basically a quadrilateral flat plate shape, and can be deformed into a form to avoid interference with other components provided in the first dust receiving space S1. For example, in order to prevent the rotating plate 5153 from interfering with the rotation radius of the inlet cover 5163 when the inlet cover 5163 opens the dust inlet 5161a, a cutout can be formed at the upper end of the rotating plate 5153 (see Figure 30).

Specifically, the upper end of the rotating plate 5153 may be provided farther from the ground than the upper end of the rotating shaft member 5151. Therefore, the distance from the rotation axis of the inlet cover 5163 to the rotating plate 5153 may be larger than the diameter of the inlet cover 5163.

Through this configuration, even if the inlet cover 5163 is rotated, contact with the compression rotation part 515 can be avoided. That is, according to the embodiment of the present invention, the inlet cover 5163 and the compression rotation part 515 can be prevented from interfering with each other.

The rotating plate 5153 can rotate in forward and reverse directions. Based on when the first dust storage space S1 is viewed from above (that is, when the first collector 510 is viewed from above), clockwise rotation is defined as forward rotation, and counterclockwise rotation is defined as reverse rotation.

When the rotating plate 5153 rotates, it can come into contact with the dust in the collector body 511 and can move the dust.

When the rotating plate 5153 rotates in the forward direction, one surface of the rotating plate 5153 and one surface of the fixed plate 5152 contact each other to compress dust. Likewise, when the rotating plate 5153 rotates in the reverse direction, the other surface of the rotating plate 5153 meets the other surface of the fixed plate 5152 to compress dust. That is, some of the compressed dust appears near one surface of the fixed plate 5152, while the rest appears near the other surface of the fixed plate 5152.

Compression rotation 515 may also include cleaning members 5154 .

Referring to FIGS. 24 and 26 , the cleaning member 5154 is coupled to one end of the rotating plate 5153 on the opposite side to the position where the rotating shaft member 5151 is provided. That is, one side end of the rotating plate 5153 is coupled to the rotating shaft member 5151 and the other side end is coupled to the cleaning member 5154.

The cleaning member 5154 may be provided to rotate together with the rotating plate 5153 in a state of contact with the screen 5121. More specifically, one side edge of the cleaning member 5154 may be disposed to contact one surface of the screen 5121.

In this way, when the cleaning member 5154 rotates together with the rotating plate 5153, the cleaning member 5154 can rotate while scraping the screen 5121, and can remove foreign matter attached to the screen 5121. The cleaning member 5154 may be a washer made of rubber or other materials.

Therefore, according to the embodiment of the present invention, dust can be compressed by rotating the compression rotating part 515, and the capacity of collecting dust in the first collector 510 can be increased.

Meanwhile, as mentioned above, the first collector 510 may include the transmission gear 514.

The transmission gear 514 may be coupled to the bottom cover 517 of the first collector 510 . When the first collector 510 is inserted into the collector receiving space 360a, the transmission gear 514 and the driving gear 3621 may mesh with each other, and the rotational power of the compression motor 3622 may be transmitted to the compression rotation part 515 via the driving gear 3621 and the transmission gear 514.

The transmission gear 514 and the driving gear 3621 will be described in detail below with reference to FIGS. 27 and 28 and 24 .

FIG. 27 is a view showing the enlargement drive gear 3621 and the enlargement transmission gear 514 according to the embodiment of the present invention. FIG. 28 is a perspective view of the driving gear 3621 viewed from the bottom according to an embodiment of the present invention.

The transmission gear 514 may be connected to the rotation shaft member 5151 of the compression rotation part 515 . Gear teeth 5142 meshing with the driving gear 3621 are provided on the outer periphery of the lower part of the transmission gear 514 . A gear shaft 5141 coaxially connected to the rotation shaft member 5151 is provided at the upper center of the transmission gear 514 .

The gear shaft 5141 can be inserted into the storage space of the collector body 511 through the hole formed in the bottom cover 517 . The gear shaft 5141 may be configured to be inserted into a cavity within the rotation shaft member 5151. That is, the diameter of the outer peripheral surface of the gear shaft 5141 may be smaller than the diameter of the outer peripheral surface of the rotation shaft member 5151 .

The gear shaft 5141 and the rotation shaft member 5151 may have a mechanical structure that meshes with each other so as to rotate at the same angular speed. For example, the mechanical structure may be a protrusion and groove structure.

The driving gear 3621 may include: a gear body 3621a; a shaft connector 3621b; and gear teeth 3621c.

The gear body 3621a forms the exterior of the drive gear 3621. Gear teeth 3621c meshing with the gear teeth 5142 of the transmission gear 514 are formed on the gear body 3621a. A pattern 3621d in which protrusions and grooves are continuously alternated may be formed on the lower circumference of the gear body 3621a.

The upper diameter of the gear body 3621a on which the gear teeth 3621c are provided and the lower diameter of the gear body 3621a on which the pattern 3621d is formed may be different from each other.

A shaft connector 3621b connected to the motor shaft of the compression motor 3622 is formed in the center of the gear body 3621a. The shaft connector 3621b may be formed in a cylindrical shape within the gear body 3621a. The shaft connector 3621b may have a hole having a shape corresponding to the motor shaft so that the motor shaft is inserted therein.

Therefore, when the compression motor 3622 rotates, the drive gear 3621 will rotate together.

A plurality of ribs 3621e may be radially provided on the outer peripheral surface of the shaft connector 3621b to support the shape of the shaft connector 3621b.

The pattern 3621d is formed on the driving gear 3621 so that the widths of protrusions adjacent to each other are different, and the widths of grooves adjacent to each other are also different. The protrusions and grooves in the formation pattern 3621d may be defined as phases distinguished by width.

Here, the phase sequence of the arrangement pattern 3621d may vary according to the first direction d1 relative to the circumference of the gear body 3621a and the second direction d2 opposite to the first direction d1.

Pattern 3621d may consist of a set of four phases. Here, the first phase and the third phase may be formed in the form of protrusions, and the second phase and the fourth phase may be formed in the form of grooves. In other words, protrusions and grooves may be formed alternately.

Here, the widths of the first phase to the fourth phase may be different, and each phase may be distinguished by the size of the width. Taking the embodiment shown in Figure 28 as an example, a protrusion with a width of 1.2 mm can define the first phase, a groove with a width of 0.8 mm can be defined as the second phase, and a protrusion with a width of 2.0 mm can be defined as the third phase. A groove with a width of 1.6 mm can be defined as the fourth phase.

When the gear body 3621a of the driving gear 3621 is inspected while moving in the first rotation direction rd1, the arrangement sequence of each phase can be repeated in the order of 1-2-3-4. Therefore, when the gear body 3621a of the drive gear 3621 is inspected while moving in the second rotation direction rd2 opposite to the first rotation direction rd1, each phase repeats in the order of 4-3-2-1.

In this way, through the directional arrangement of the pattern 3621d formed on the driving gear 3621, the controller 700 described below can detect whether the driving gear 3621 is currently rotating in the first rotation direction rd1 or in the second rotation direction rd2.

FIG. 29 is a perspective view showing a state in which the first collector 510 is inserted into the chamber body 361 according to an embodiment of the present invention. 30 is a view showing an air flow channel related to dust collection in a state where the first collector 510 is inserted into the chamber body 361 according to an embodiment of the present invention.

Large dust will be separated when the air introduced into the first dust storage space S1 of the collector body 511 through the first flow path 381 has passed through the screen 5121. Air without large dust will enter the second dust storage space S2.

Then, even if the fine dust has passed through the cyclone 513 in the air introduced into the second dust storage space S2, it will be separated. The air introduction without fine dust is provided in the collector flow path 518 within the collector body 511 .

The air that has left the collector flow path 518 flows to the dust collection motor 391 via the pre-filter module 470 .

The detailed structure of the second collector 520 will be described below.

32 is a view showing components related to separation and deployment of the second collector 520 according to an embodiment of the present invention. 33 is a cross-sectional view of the second collector 520 viewed from its side according to an embodiment of the present invention.

Referring to FIGS. 32 and 33 , the second collector 520 may include: a dust bag 521 ; an outer flat plate 522 ; and an inner flat plate 523 .

The dust bag 521 is configured to receive dust sucked in from the first vacuum cleaner 200 and store it therein.

When the suction force is generated by the dust collection motor 391, the volume of the dust collection bag 521 can be increased and the dust can be contained within the dust collection bag 521. Therefore, the dust bag 521 may be made of breathable material. More specifically, the dust bag 521 may be made of a material through which air can pass but foreign matter such as dust cannot pass. For example, the dust bag 521 may be made of non-woven material and may have a hexahedral shape with an apparent volume increased.

A dust inlet 5212 is formed in the dust bag 521 . The dust inlet 5212 is formed on the top of the dust bag 521 to pass through the dust bag 521 and is a path for introducing air and dust introduced from the air inlet 3611 of the chamber body 361 to the inside of the dust bag 521 .

The dust bag 521 may include a light-transmitting hole 5211. The light-transmitting hole 5211 may be formed to pass through the dust bag 521 . The light-transmitting hole 5211 may be formed at a position facing one surface of the transmissive panel 524 to be described below. That is to say, the light-transmitting hole 5211 may be provided in front of the dust inlet 5212. When the second collector 520 is fully inserted into the collector storage space 360a, the disinfection module 450 can be disposed above the light-transmitting hole 5211. Therefore, the sterilizing light can be irradiated into the dust collection bag 521 through the transmission panel 524 .

The outer flat plate 522 may be coupled to the outer top of the dust bag 521 .

The outer flat plate 522 may include a quadrilateral flat plate body 5221 .

Parts of the left and right ends of the flat body 5221 can be inserted into the sliding space of the track body 3631. From another perspective, the left and right ends of the flat plate body 5221 can be assembled and coupled to the track body 3631, and one surface of the flat plate body 5221 can be supported by the inner bottom surface of the track body 3631. Through this configuration, the flat plate body 5221 can be slidably inserted into the track body 3631.

A dust inlet 5222 is formed in the flat body 5221. The dust inlet 5222 is a path that guides the air and dust introduced from the air inlet 3611 of the chamber body 361 to the inside of the dust bag 521 .

The outer plate 522 may contain a handle 5223.

A handle 5223 may be coupled to the front end of the tablet body 5221. The handle 5223 can be integrally formed with the flat body 5221. The handle 5223 may be vertically connected to the tablet body 5221.

The user can hold the handle 5223 to push the outer plate 522 into the track body 3631. The user can hold the handle 5223 to remove the outer plate 522 from the track body 3631 .

Outer panel 522 may include connecting members 5224.

The connection member 5224 may be disposed in the rear of the dust inlet 5222. The connection member 5224 may be formed to protrude from the bottom surface of the outer plate 522 by a predetermined length. The connecting member 5224 may pass through the dust bag 521 and be coupled to the inner panel 523 described below.

Outer plate 522 may contain support members 5225.

A support member 5225 may be provided in front of the outer plate 522. The support member 5225 may be formed to protrude from the bottom surface of the outer plate 522 by a predetermined length.

Support members 5225 are formed in the form of ribs on the left and right sides of the outer flat plate 522, respectively. Based on the state of the outer flat plate 522 being inserted into the track body 3631, the lower end of the support member 5225 may be in contact with the lower inner surface of the track body 3631.

When the second collector 520 is inserted into the collector receiving space 360a, the front part will be lifted by the support member 5225. That is, when the second collector 520 is fully inserted into the collector storage space 360a, the second collector 520 will tilt backward and downward (see Figure 35).

Through this configuration, the outer plate 522 can be supported toward the air inlet 3611 of the chamber body 361 in a lifted state.

As mentioned above, the open cross section of the air inlet 3611 in the embodiment of the present invention has a rearward and downward bevel angle. Here, since the second collector 520 is also inserted into the track portion 363 in a backward and downward tilted state, the air inlet 3611 and the dust inlet 5222 have bevel angles in the same direction, so that they can be sealed without being spaced apart. .

The outer plate 522 may include light-transmitting holes 5226.

A light-transmitting hole 5226 may be formed to pass through the flat plate body 5221. The light-transmitting hole 5226 may be formed at a position facing one surface of the transmissive panel 524 to be described below. That is to say, the light-transmitting hole 5226 may be disposed in front of the dust inlet 5222.

When the second collector 520 is fully inserted into the collector storage space 360a, the disinfection module 450 can be disposed above the light-transmitting hole 5226. Therefore, the sterilizing light can be irradiated into the dust bag 521 through the transmissive panel 524 .

The inner plate 523 may be coupled to the inner top of the dust bag 521 .

The inner flat plate 523 may include a quadrilateral flat plate body 5231 .

A dust inlet 5232 is formed in the plate body 5231. The dust inlet 5232 is a path that guides the air and dust introduced from the air inlet 3611 of the chamber body 361 to the inside of the dust bag 521 .

Inner plate 523 may include side walls 5233.

The side wall 5233 is configured to restrict and guide the flow of air introduced into the dust bag 521 . Side wall 5233 may be disposed adjacent dust inlet 5232. The side wall 5233 may be formed to protrude downward from the inner surface of the flat plate body 5231. That is, the side wall 5233 may be provided to extend toward the inner space of the dust bag 521 .

The side walls 5233 may be symmetrically provided on the left and right sides of the dust inlet 5232. Therefore, the side wall 5233 can block the air introduced into the dust inlet 5232 from flowing to the left or right.

At the same time, when the inlet cover 525 described later is opened, the rear flow of air can also be blocked.

Therefore, the air introduced into the dust inlet 5232 flows forward and downward.

Through this configuration, the introduced dust can be effectively exposed to the sterilizing light shining in front of the dust inlet 5232.

Inner plate 523 may include connecting member insertion slots 5234.

The connection member insertion groove 5234 may be provided behind the dust inlet 5232. The connection member insertion groove 5234 may be formed in a form through which the flat plate body 5231 passes. The connection member 5224 of the outer plate 522 may be inserted into the connection member insertion slot 5234.

Inner plate 523 may contain inlet tube 5235.

The inlet tube 5235 may be coupled to the lower surface of the flat plate body 5231. Inlet tube 5235 may be provided to surround dust inlet 5232. The inlet tube 5235 may be integrally formed with the flat plate body 5231. The open cross-section of the inlet tube 5235 may have a rearward and downward bevel.

The lower end of the inlet pipe 5235 can be closed by an inlet cover 525 described later. Therefore, the dust inlet 5232 can also be closed.

Inner plate 523 may contain inlet cover securing member 5236.

The inlet cover fixing member 5236 may be provided behind the dust inlet 5232. The inlet cover fixing member 5236 may be coupled to the lower surface of the flat plate body 5231 in a form surrounding the connection member insertion groove 5234. The inlet cover fixing member 5236 may be integrally formed with the flat plate body 5231.

An inlet cover insertion groove 5236a may be formed in the inlet cover fixing member 5236. At least a portion of the inlet cover 525 may be inserted and fixed in the inlet cover insertion groove 5236a. The inlet cover insertion groove 5236a has a rearward and downward slope, and can extend left and right. Therefore, the inlet cover 525 can be inserted rearwardly and downwardly from the front upper portion.

Transmissive panel 524 may be coupled to inner plate 523 .

When the second collector 520 is inserted into the chamber body 361, the transmission panel 524 is disposed at a position corresponding to the position where the sterilization module 450 is disposed. That is, when the second collector 520 is inserted into the chamber body 361, the sterilization module 450 and the transmission panel 5161b are disposed to face each other.

The transmissive panel 524 is made of a material that allows the disinfection light energy emitted from the disinfection module 450 to pass toward the interior of the collector body 511 . For example, transmissive panel 524 may be made of polymethylmethacrylate (PMMA) material.

An inlet cover 525 for opening and closing the dust inlet 5232 may be coupled to the interior of the inner plate 523 . An inlet cover 525 may be provided at one end of the inlet tube 5235.

The access cover 525 may be made of a resilient material. For example, access cover 525 may be made of rubber material.

The inlet cover 525 can open one side of the inlet pipe 5235 through the suction force of the dust collection motor 391. That is, the inlet cover 525 can be opened toward the inner space of the dust bag 521 .

One side of the inlet cover 525 may be inserted into and coupled into the inlet cover insertion slot 5236a.

While the inlet cover insertion slot 5236a has a larger rearward and downward inclination angle, the open cross-section of the inlet tube 5235 has a smaller rearward and downward inclination angle than the inlet cover insertion slot 5236a. When the inlet cover 525 is inserted into the inlet cover insertion groove 5236a, the shape of the inlet cover 525 is changed in such a manner that it is bent at one point thereof.

Here, the restoring force is applied to the inlet cover 525 in the direction in which the inlet cover 525 is to be expanded again based on the bending point.

With this arrangement, in a state where the inlet cover 525 is inserted into the inlet cover insertion groove 5236a, the inlet cover 525 can be in close contact with the inlet pipe 5235. That is, when the dust collection motor 391 is not driven, the inlet cover 525 will not deflect due to its own weight.

The inlet cover 525 can keep the dust inlet 5232 closed when the dust collection motor 391 is not driven. When the dust collection motor 391 starts to operate, the inlet cover 525 can open the dust inlet 5232.

When the dust collection motor 391 is running, the inlet cover 525 opens the inlet pipe 5235 and deforms toward the inner space of the dust collection bag 521. When the dust collection motor 391 stops, the inlet cover 525 recovers through elasticity and closes the inlet pipe 5235.

Therefore, when the second collector 520 is separated from the vacuum cleaner docking station 300, dust flying, winged insects escaping, or odor spreading can be prevented.

In addition, when the dust collection motor 391 is not driven even when the second dust collector 520 is coupled to the vacuum cleaner docking station 300, because the inlet cover 525 closes the inlet pipe 5235, it is possible to prevent dust or odor from flowing back through the first flow path 381. Effect.

34 is a perspective view showing a state in which the second collector 520 is inserted into the chamber body 361 according to an embodiment of the present invention. 35 is a view showing an air flow channel related to dust collection in a state where the second collector 520 is inserted into the chamber body 361 according to an embodiment of the present invention.

When the air flow is generated by the suction force of the dust collection motor 391, the air containing foreign matter and flowing from the inside of the dust box 220 of the first vacuum cleaner 200 will move to the dust collection bag 521 through the first flow path 381, leaving only the foreign matter behind. In the dust bag 521 and then out of the dust bag 521 .

Here, dust introduced through the first flow path 381 will be prevented from flowing left and right by the side walls 5233 and prevented from flowing backward by the inlet cover 525 . Therefore, as shown by the arrows in FIG. 35 , the dust will flow forward and downward toward the sterilizing light irradiated by the sterilizing module 450 .

In addition, the air leaving the dust collection bag 521 will flow to the dust collection motor 391 through the pre-filter module 470 .

On the other hand, when the dust collecting motor 391 is driven to form airflow in the second dust collector 520, the gear through hole 3613a is still exposed without being blocked, so the suction force is also applied to the gear through hole 3613a. (See the direction of the dotted arrow in Figure 35)

As a result, when the suction force is directly applied to the compression motor 3622 through the gear through hole 3613a, it may cause the compression motor 3622 to malfunction.

36 is an enlarged cross-sectional view of the sealing member 3623 that seals the gear through hole 2623a according to an embodiment of the present invention.

In embodiments in accordance with the present invention, the compression driver 362 may also include a sealing member 3623 disposed between the drive gear 3621 and the chamber body 361 .

The sealing member 3623 may be provided along the entire outer circumference of the gear body 3621a of the driving gear 3621. The sealing member 3623 may be provided between the outer surface of the gear body 3621a of the driving gear 3621 and the lower outer surface of the chamber body 361.

In this way, the sealing member 3623 can seal between the gear through hole 3613a and the compression motor 3622, thereby blocking the air flow between the compression motor 3622 and the collector receiving space 360a.

The sealing member 3623 may include a first sealing portion in contact with the chamber body 361 and a second sealing portion in contact with the gear body 3621a. The first sealing part and the second sealing part may be connected to each other at one side end and may be spaced apart from each other at the other side end.

With this configuration, when the suction force is applied by the dust collecting motor 391, the sealing portion is compressed in a direction in which the other side of the first sealing portion and the other side of the second sealing portion approach each other. Therefore, the sealing force is further strengthened by driving the dust collection motor 391, and the suction force is prevented from being directly applied to the compression motor 3622.

At the same time, the vacuum cleaner docking station may also include a controller 700.

Controller 700 is the element that controls the operation of each component of the vacuum cleaner dock. Controller 700 may be mounted on a printed circuit board.

Controller 700 may include any type of device capable of processing data, such as a processor. A "processor" as used herein may refer to a data processing device embedded in hardware that has physically structured circuitry to perform the functions represented by the code or commands contained in the program. Examples of such data processing devices embedded in hardware may include microprocessors, central processing units (CPUs), processor cores, multiprocessors, application specific integrated circuits (ASICs), field programmable gate arrays (FPGAs) ). However, the scope of the present invention is not limited thereto.

In embodiments of the present invention, the controller 700 may detect changes in the rotational direction of the compression motor 3622.

As mentioned above, when the compression motor 3622 rotates in one direction, if the force applied to the compression motor 3622 is greater than or equal to a set value, the rotation direction of the compression motor 3622 will change to another direction. Here, the force applied to the compression motor 3622 is the resistance (torque) generated by the rotating plate 5153 compressing dust. When the resistance reaches a set value, the rotation direction of the compression motor 3622 will be changed.

That is, the rotation direction of the compression motor 3622 will change only when the compression motor 3622 is connected to the rotating plate 5153 and the rotating plate 5153 compresses dust.

The controller 700 can control the drive of the compression motor 3622 during any stage of the dust removal process.

In a possible embodiment, the compression motor 3622 may be driven when the first vacuum cleaner 200 is coupled to the coupling part 320 . Information related to the coupling of the first vacuum cleaner 200 may be detected by a coupling sensor provided on one side of the coupling part 320 and transmitted to the controller 700 .

In another possible embodiment, the driving of the compression motor 3622 may be performed after the driving of the dust collection motor 391 is completed.

In another possible embodiment, the dust collection motor 391 may be driven before and after the compression motor 3622 is driven, respectively.

The controller 700 may detect whether the rotation direction of the compression motor 3622 changes within a predetermined time period from the time when the compression motor 3622 starts operating. The predetermined time period should be set to be sufficiently larger than an expected time period from when the rotating plate 5153 starts to rotate at the initial position to when the rotating plate 5153 contacts a surface of the fixed plate 5152.

The change in the rotation direction can be detected by detecting the arrangement sequence of the patterns 3621d formed on the driving gear 3621. Therefore, the compression driver 362 may also include a photointerrupter (not shown) disposed adjacent the drive gear 3621 .

If the phase of the pattern 3621d detected by the photointerrupter has an arrangement sequence of 1-2-3-4, the compression motor 3622 rotates in the first direction. If the phase of the pattern 3621d detected by the photointerrupter has an arrangement of 4-3-2-1, the compression motor 3622 rotates in the second direction (see Figure 28).

Controller 700 can drive compression motor 3622 regardless of the type of collector 500 currently coupled to vacuum cleaner dock 300.

If the first collector 510 is inserted into the chamber body 361, the rotation direction of the compression motor 3622 must change within the predetermined time period.

If the second collector 520 is inserted into the chamber body 361, the compression motor 3622 will not bear the load even after the predetermined period of time. Therefore, the compression motor 3622 only rotates in the same direction, and the direction of rotation does not change.

That is, the controller 700 rotationally drives the compression motor 3622 and determines the type of collector 500 currently coupled to the vacuum cleaner docking station 300 based on whether the rotation direction of the compression motor 3622 changes within the predetermined time period.

Although the present invention is described above through specific embodiments, the purpose is to explain the present invention in detail. The present invention is not limited thereto. A person of ordinary skill in the technical field to which the present invention belongs may make modifications or improvements within the scope of the present invention.

All simple modifications or changes of the present invention are within the protection scope of the present invention. The specific protection scope of the present invention will be clearly described by the appended claims.
