Description

[BACKGROUND]

[Technical Field]

Embodiments of the present disclosure relate to a cleaner station that may be coupled to a vacuum cleaner to collect dust inside a cleaner dust bin.

[Background of the Disclosure]

Stick vacuum cleaners (hereinafter referred to as "cleaners") had a small dustbin capacity for storing collected dust, which was inconvenient for users to have to empty the dustbin every time.
Accordingly, the use of cleaner stations configured to suck up and capture dust in a dust bin through the suction power of a dust collecting motor so that users do not have to manually remove dust from the dust bin is expanding.
This cleaner station includes a housing, a dust collecting motor arranged inside the housing, and a dust bag-shaped collection part for receiving the collected dust, and are configured to be combined with a cleaner or a dust bin of a cleaner.
The vacuum cleaner station is convenient in that it can automatically empty the vacuum cleaner's dust bin, and the dust bag included in the vacuum cleaner station has a larger volume than the dust bin provided in most vacuum cleaners, so it has the advantage of extending the cycle in which dust must be disposed of.
Meanwhile, the dust bag-shaped collection part has a simple structure and can be thrown away in the trash can as a whole without having to remove the dust separately or clean the inside, so it has the advantage of user convenience.
However, since the dust bag cannot be washed on the inside, it must be purchased and replaced periodically, which may be a burden on some users due to the cost.
In this regard, US Patent Publication No. 10595692 is presented as a prior art patent document.
This prior art patent document discloses the embodiment of a discharge station having a bin-shaped collection part as a discharge station that docks with a robot cleaner.
Unlike dust bags, the bin-shaped dust collection part has the advantage of being easy to clean internally, so it can be used semi-permanently by simply removing the dust contained therein.
However, some users may find dust removal and cleaning, which are separate tasks, cumbersome.
In this way, when the form of the dust collection part is fixed to one type, it becomes difficult to satisfy the preferences of different users.

[DETAILED DESCRIPTION OF THE INVENTION]

[Technical Problem]

Accordingly, one object of the present disclosure is to solve the above-noted disadvantages of the prior art, and to provide a cleaner station configured to satisfy the diverse preferences of users who prefer different types of capture devices.
In addition, another object of the present disclosure is to provide a cleaner station that can distinguish between different types of dust collection parts currently in use.
Aspects according to the present disclosure are not limited to the above ones, and other aspects and advantages that are not mentioned above can be clearly understood from the following description and can be more clearly understood from the embodiments set forth herein.

[Technical Solution]

To solve the objects of the present disclosure, a cleaner station may include a housing coupled to a dust bin of a cleaner; a dust collection motor disposed inside the housing and configured to generate a suction force sucking dust inside the dust bin; a dust collection part having a dust accommodating space that collects the dust sucked from the dust bin by the dust collection motor; and a chamber part disposed in the housing and having a dust collection part accommodating space to which the dust collection part is detachably coupled.
The dust collection part coupled to the chamber part may be provided with a first dust collection part formed in a bucket shape and including a cyclone as a dust separation means, and a second dust collection part having a dust accommodating space with a variable size and including a dust bag made of breathable material as a dust separation means, which are compatible.
The cleaner station may further include a compression drive unit disposed in the outside of the dust collection part accommodating space and configured to generate power to rotate a compression rotation unit configured to compress dust collected inside the first dust collection part.
In the cleaner station according to the embodiments, the type of the dust collection part currently coupled to the chamber part may be distinguished based on the operation form of the compression drive unit.
The compression drive unit may include a compression motor disposed in the outside of the dust collection accommodating space; and a drive gear axially connected to the compression motor in the outside of the dust collection part accommodating space and configured to transmit the power generated by the compression motor to the compression rotation unit.
The first dust collection part may include a transmission gear coupled to the compression rotation unit and configured to transmit power from the compression drive unit to the compression rotation unit.
The cleaner station of claim 1, wherein a gear passage hole configured to expose at least a portion of the compression drive unit toward the inside of the dust collection part accommodating space may be formed in a lower portion of the chamber part.
The cleaner station may further include a controller configured to detect changes in rotation direction of the compression drive unit.
The controller may be configured to determine the type of the dust collection part coupled to the chamber part based on whether change in the rotation direction of the compression drive unit within a predetermined time period.
The compression drive unit may be rotated for a preset time before the dust collection motor is driven after the dust collection part is coupled to the chamber part.
It may be determined that the fist dust collection part is coupled to the chamber part if the rotation direction of the compression drive unit is changed to the opposite direction within the preset time.
It may be determined that the second dust collection part is coupled to the chamber part, if the rotation direction of the compression drive unit remains the same even after the preset time has elapsed.
Only when the first dust collection part is coupled to the chamber part, the compression drive unit may be driven after the dust collection motor is driven.

[Advantageous Effects]

According to the embodiments of the present disclosure, the user can combine either the first dust collection part formed in a bucket shape with a fixed dust-accommodating space size or the second dust collection part formed in a dust bag shape with a variable dust-accommodating space size to the cleaner station. Accordingly, there is an advantage of satisfying various preferences of users who prefer different types of dust collection parts.
Furthermore, according to the embodiments of the present disclosure, the dust collection part unit currently coupled to the cleaning station can be distinguished. Accordingly, the cleaning station can be efficiently driven according to the shape of the dust collection part.
Still further, according to the embodiments of the present disclosure, the dust collection part can be distinguished by utilizing the compression drive unit equipped for dust compression without having an additional sensor.
In addition to the above-described effects, specific effects of the present invention will be described together with the following detailed description for implementing the present invention.

FIG. 1 is a view to describe a vacuum cleaner according to one embodiment of the present disclosure. FIG. 2 is a view of the vacuum cleaner viewed from a different angle. FIG. 3 is a view to describe a lower side of a dust bin of the vacuum cleaner according to one embodiment. FIG. 4 is a view to describe a cleaner system according to one embodiment.
Referring to FIGS. 1 to 4, the cleaner system 3 according to embodiments of the present disclosure may include a cleaner 200 and a cleaner station 300.
The cleaner system 3 may include the cleaner station 300. The cleaner 200 may be mounted to the cleaner station. The cleaner 200 may be mounted to the lateral surface of the cleaner station 300. The cleaner station 300 may be configured to remove dust from the inside of the dust bin 220.
First, referring to FIGS. 1 to 3, the structure of the cleaner 200 will be described as follows.
The cleaner 200 may mean a vacuum cleaner operated manually by a user. For example, the cleaner 200 may mean a handheld cleaner or stick cleaner.
The cleaner 200 may may be mounted on the cleaner station 300. The cleaner 200 may be supported by the cleaner station 300. The cleaner 200 may be mounted to the to the cleaner station 300.
Meanwhile, in the embodiment, the direction of the vacuum cleaner 200 can be defined based on the time when the bottom surface (or lower surface) of a dust bin 220 and a battery housing 230 are placed on the ground.
At this time, the front may refer to the direction in which a suction port 212 is arranged based on a suction motor 214, and the rear may refer to the direction in which a handle 216 is arranged based on the suction motor 214. In addition, the direction in which the suction port 212 is arranged on the right when viewed from the suction motor 214 may be referred to as the right, and the direction in which the handle is arranged on the left may be referred to as the left.
The cleaner 200 may include a cleaner body 210. The cleaner body 210 may include a body housing 211, a suction portion 212, a dust separation part 213, a suction motor 214, an air discharge cover 215, a handle 216, and an operation part 218.
The body housing 211 may define the exterior of the cleaner 200. The body housing 211 may provide a space that accommodates the suction motor 214 and a filter (not shown). The body housing 211 may be formed in a cylinder-like shape.
The suction port 212 may protrude outward from the body housing 211. As one example, the suction port 212 may be formed in a cylindrical shape with an open inside. The suction port 212 may be coupled to an extension pipe 250. The suction port 212 may provide a path through which air containing dust may flow (hereinafter, referred to as 'the suction path').
The dust separation part 213 may be in communication with the suction port 212. The dust separation part 213 may be configured to separate dust sucked therein through the suction port 212. The inner space of the dust separation part 213 may be in communication with the inner space of the dust bin 220.
For example, the dust separation part 213 may include at least one cyclone unit configured to separate dust by cyclone flow. In addition, the space inside the dust separation part 213 may be in communication with the suction path. Accordingly, the air and dust sucked through the suction port 212 may flow spirally along the inner surface of the dust separation part 213. Accordingly, a cyclone flow may occur in the inner space of the dust separation part 213.
The dust separation part 213 may be connected to the suction port 212 and is configured to apply the principle of a dust collector that uses centrifugal force to separate dust sucked into the cleaner body 210 through the suction port 212.
The dust separation part 213 may further include a secondary cyclone configured to separate dust again from the air discharged from the cyclone. At this time, the secondary cyclone may be positioned inside the cyclone so as to minimize the size of the dust separation part. The secondary cyclone may include multiple cyclone bodies arranged in parallel. Air discharged from the cyclone may be divided and passed through the multiple cyclone bodies. The secondary cyclone may include multiple cyclone bodies arranged in parallel. Air discharged from the cyclone may be divided and passed through the multiple cyclone bodies.
At this time, the axis of the cyclone flow of the secondary cyclone may also extend in the vertical direction, and the axis of the cyclone flow of the cyclone and the axis of the cyclone flow of the secondary cyclone may form a coaxial line in the vertical direction, which may be collectively referred to as the axis of the cyclone flow of the dust separation unit 213.
The suction motor 214 can generate a suction force to suck in air. The suction motor 214 can be accommodated in the body housing 211. The suction motor 214 can generate a suction force by rotation. For example, the suction motor 214 can be provided in a similar cylindrical shape.
The air exhaust cover 215 may be placed on one axial side of the body housing 211. The air exhaust cover 215 may accommodate a filter for filtering air. For example, the air discharge cover 215 may accommodate a HEPA filter.
An air discharge hole may be formed in the air discharge cover 215 to discharge air sucked in by the suction force of the suction motor 214.
A flow guide may be arranged in the air discharge cover 215. The flow guide may guide the flow of air discharged through the air discharge hole.
The handle 216 can be gripped by the user. The handle 216 can be positioned at the rear of the suction motor 214. As an example, the handle 216 can be formed in a shape similar to a cylinder. Alternatively, the handle 216 may be formed in a curved cylindrical shape. The handle 216 may be positioned at a predetermined angle with respect to the body housing 211, the suction motor 214, or the dust separation part 213.
The handle 216 may include a grip portion 216a formed in a pillar shape so that the user can hold it, a first extension portion 216b connected to one end in the longitudinal direction (or axial direction) of the grip portion 216a and formed to extend toward the suction motor 214, and a second extension portion 216c connected to the other end in the longitudinal direction (or axial direction) of the grip portion 216a and formed to extend toward the dust bin 220.
The upper surface of the handle 216 may partially form the exterior of the upper surface of the cleaner 200. This may prevent a component of the cleaner 200 from coming into contact with the user's arm when the user holds the handle 216.
The first extension portion 216b may extend from the grip portion 216a toward the body housing 211 or the suction motor 214. At least a portion of the first extension portion 216b may extend in the horizontal direction.
The second extension portion 216c may extend from the grip portion toward the dust bin 220. At least a portion of the second extension portion 216c may extend in a horizontal direction.
The operation part 218 may be placed on the handle 216. The operation part 218 may be placed on an inclined surface formed in the upper area of the handle 216. The user may input an operation or stop command for the cleaner 200 through the operation part 218.
The cleaner 200 may include the dust bin 220. The dust bin 220 may be connected to the dust separation unit 213. The dust bin 220 may store dust separated from the dust separation part 213.
The dust bin 220 may include a dustbin body 221, a discharge cover 222, a dustbin compression lever 223, and a compressor (not shown).
The dust bin body 221 can provide a space for storing dust separated from the dust separation part 213. For example, the dust bin body 221 can be formed in a shape similar to a cylinder.
The lower surface (or bottom surface) of the dust bin body 221 may be partially open. In addition, a lower extension portion 221a may be formed on the lower surface (or bottom surface) of the dust bin body 221. The lower extension portion 221a may be formed to block a portion of the lower surface of the dust bin body 221.
The dust bin 220 may include a discharge cover 222. The discharge cover 222 may be placed on the lower surface of the dust bin 220.
The discharge cover 222 may be provided to open and close one end of the length direction of the dust bin body 221. Specifically, the discharge cover 222 may selectively open and close the lower part of the dust bin 220 that opens downward.
The discharge cover 222 may include a cover body 222a and a hinge unit 222b. The cover body 222a may be formed to block a portion of the lower surface of the dust bin body 221. The cover body 222a may rotate downward based on the hinge unit 222b. The hinge unit 222b may be arranged adjacent to the battery housing 230. A torsion spring 222d may be provided in the hinge unit 222b. Accordingly, when the discharge cover 222 is separated from the dust bin body 221, the cover body 222a may be supported in a state of being rotated by a predetermined angle or more about the hinge unit 222b as an axis in the dust bin body 221 by the elastic force of the torsion spring 222d.
The discharge cover 222 can be coupled to the dust bin 220 through a hook connection. Meanwhile, the discharge cover 222 can be separated from the dust bin 220 through a coupling lever 222c. The coupling lever 222c can be arranged at the front of the dust bin. Specifically, the coupling lever 222c can be arranged on the outer surface of the front side of the dust bin 220. When an external force is applied, the coupling lever 222c can elastically deform a hook extended from the cover body 222a to release the hook connection between the cover body 222a and the dust bin body 221.
When the discharge cover 222 is closed, the lower surface of the dust bin 220 may be sealed by the discharge cover 222 and the lower extension 221a.
The dust bin 220 may include a dustbin compression lever 223 (see FIG. 2). The dust bin compression lever 223 may be placed outside the dust bin 220 or the dust separation part 213. The dustbin compression lever 223 may be placed outside the dust bin 220 or the dust separation part 213 so as to move up and down. The dust bin compression lever 223 may be connected to a compressor (not shown). When the dust bin compression lever 223 moves downward by an external force, the compressor (not shown) may also move downward. Through this, user convenience can be provided. The compressor (not shown) and the dust bin compression lever 223 can be returned to the original position by an elastic member (not shown). Specifically, when the external force applied to the dust bin compression lever 223 is removed, the elastic member can move the dust bin compression lever 223 and the compressor (not shown) upward.
The compressor (not shown) may be disposed inside the dust bin body 221. The compressor may move within the inner space of the dust bin body 221. Specifically, the compressor may move up and down within the dust bin body 221. Through this, the compressor may compress dust within the dust bin body 221 downward. In addition, when the discharge cover 222 is separated from the dust bin body 221 and the lower part of the dust bin 220 is opened, the compressor can move from the upper part to the lower part of the dust bin 220 to remove foreign substances such as residual dust inside the dust bin 220. Through this, the suction power of the cleaner can be improved by preventing residual dust from remaining inside the dust bin 220. In addition, by preventing residual dust from remaining inside the dust bin 220, an unpleasant odor caused by residual substances can be eliminated.
The cleaner 200 may include a battery housing 230. The battery housing 230 may accommodate a battery 240. The battery housing 230 may be placed on the lower side of the handle 216. For example, the battery housing 230 may have a hexahedral shape with an open bottom. The rear surface of the battery housing 230 may be connected to the handle 216.
The battery housing 230 may include an accommodating portion that opens downward. The battery 240 may be removed through the accommodating portion of the battery housing 230.
The vacuum cleaner 200 may include a battery 240.
For example, the battery 240 may be detachably coupled to the vacuum cleaner 200. The battery 240 may be detachably coupled to the battery housing 230.
For example, the battery 240 can be integrally inserted into the battery housing 230 from the lower surface of the battery housing 230. With this configuration, the portability of the cleaner 200 can be improved.
In contrast, the battery 240 may be integrally provided inside the battery housing 230. In this case, the lower surface of the battery 240 is not exposed to the outside.
When the battery 240 is coupled to the battery housing 230 according to an embodiment, the lower surface of the battery 240 may be exposed to the outside. Since the battery 240 may be placed on the floor when the cleaner 200 is placed on the floor, the battery 240 may be directly separated from the battery housing 230. In addition, since the lower surface of the battery 240 is exposed to the outside and comes into direct contact with the external air of the battery 240, the cooling performance of the battery 240 can be improved.
Meanwhile, when the battery 240 is integrally fixed to the battery housing 230, the structure for attaching and detaching the battery 240 and the battery housing 230 can be reduced, so the overall size of the vacuum cleaner 200 can be reduced and its weight can be reduced.
The cleaner 200 may include an extension pipe 250. The extension pipe 250 may be communicated with a cleaning module 260. The extension pipe 250 may be communicated with the cleaner body 210. The extension pipe 250 may be communicated with the suction port 212 of the cleaner body 210. The extension pipe 250 may be formed in a long cylindrical shape.
The cleaner body 210 can be connected to the extension pipe 250. The cleaner body 210 can be connected to the cleaning module 260 through the extension pipe 250. The cleaner body 210 can generate suction force through the suction motor 214 and provide suction force to the cleaning module 260 through the extension pipe 250. External dust can be introduced into the cleaner body 210 through the cleaning module 260 and the extension pipe 250.
The cleaner 200 may include the cleaning module 260. The cleaning module 260 may be connected to the extension pipe 250. Accordingly, external air may be drawn into the main body 210 of the cleaner 200 through the cleaning module 260 and the extension pipe 250 by the suction force generated in the cleaner body 210 of the cleaner 200.
Dust in the dust bin 220 of the cleaner 200 can be collected by gravity into the dust collection part 500 of the cleaner station 300. At the same time, dust in the dust bin 220 can be collected by the dust collection part 500 of the cleaner station 300 by the suction force of a dust collecting motor 391 placed inside the cleaner station 300. This can provide convenience to users by removing dust inside the vacuum cleaner dust bin without separate operation from the user. In addition, it can eliminate the inconvenience of the user having to empty the dust bin every time. In addition, it can prevent dust from flying when the dust bin is emptied.
The cleaner 200 can be coupled to the lateral surface of the housing 310. Specifically, the cleaner body 210 of the cleaner 200 can be mounted on the mounting part 320. More specifically, the dust bin 220 and the battery housing 230 of the cleaner 200 can be coupled to the mounting surface 321 of the mounting part 320. The outer surface of the dust bin body 221 can be coupled to the dust bin guide surface 322. With this configuration, the central axis of the dust bin 220 can be arranged in a direction parallel to the ground, and the extension pipe 250 can be arranged along a direction perpendicular to the ground.
Hereinafter, the configuration of the cleaner station 300 according to the embodiments of the present disclosure will be described.
Referring to FIG. 4, the cleaner 200 may be mounted to the cleaner station 300. Specifically, the cleaner body of the cleaner 200 may be mounted to the lateral surface of the cleaner station 300. More specifically, while the dust bin 220 of the cleaner 200 is coupled to the lateral surface of the cleaner station 300, this coupling may be performed through one side where the discharge cover 222 is disposed. Accordingly, when the discharge cover 222 is opened, the dust inside the dust bin 220 may be collected into the cleaner station 300 to be removed.
The cleaner station 300 may include a housing 310. The housing 310 may be configured to define the exterior of the cleaner station 300. Specifically, the housing 310 may be formed in a pillar shape having at least one outer wall surfaces. For example, the housing 310 may be formed in a shape similar to a square pillar.
The housing 310 may have a space formed therein that can accommodate the dust collection part 500 and the dust suction module 390.
The housing 310 may include a bottom surface 311, an outer wall surface 312, and an upper surface 313.
The bottom surface 311 can support the lower side of the dust suction module 390 in the gravity direction. That is, the bottom surface 311 can support the lower side of the dust collection motor 391 of the dust suction module 390.
At this time, the bottom surface 311 can be placed facing the ground. The bottom surface 311 can be placed parallel to the ground, but can also be placed at a certain angle with the ground. This configuration has the advantage of stably supporting the dust collection motor 391 and balancing the overall weight even when the cleaner 200 is mounted.
Meanwhile, according to the embodiments, the bottom surface 311 may further include a ground support portion 311a that increases the area in contact with the ground to prevent the cleaner station 300 from falling over and maintain balance. For example, the ground support portion 311a may be in the form of a plate extended from the bottom surface 311, and one or more frames may be formed to protrude and extend along the ground direction from the bottom surface 311.
The outer wall surface 312 may mean a surface formed along the direction of gravity, and may mean a surface connected to the bottom surface 311. For example, the outer wall surface 312 may mean a surface vertically connected to the bottom surface 311. In another embodiment, the outer wall surface 312 may be arranged to be inclined at a predetermined angle with the bottom surface 311.
The outer wall surface 312 may be configured to 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.
At this time, in the present embodiment, the first outer wall surface 312a may be placed on the front side of the cleaner station 300. Here, the front side may mean the surface where the cleaner 200 is exposed when the cleaner 200 is coupled to the cleaner station 300. Therefore, the first outer wall surface 312a may form the appearance of the front side of the cleaner station 300.
Meanwhile, for the purpose of understanding this embodiment, the direction is defined as follows. In this embodiment, the direction can be defined when the cleaner 200 is connected to the cleaner station 300.
When the cleaner 200 is connected to the cleaner station 300, the direction in which the cleaner 200 is exposed to the outside of the cleaner station 300 can be called the front.
From another perspective, when the cleaner 200 is mounted to the cleaner station 300, the direction in which the suction motor 214 of the cleaner 200 is arranged can be called the front. And the direction opposite to the direction in which the suction motor 214 is arranged in the cleaner station 300 can be called the rear.

FIG. 5 is a view to describe a mounting part of a cleaner station according to one embodiment.
Referring to FIG. 5, the cleaner station 300 may include a mounting part 320 for mounting the cleaner 200. Specifically, the mounting part 320 is arranged on the first outer wall surface 312a, and the dust bin 220 of the cleaner 200 may be mounted. The cleaner body 210 and the battery housing 230 of the cleaner 200 may also be mounted to the mounting part 320 together with the dust bin 220.
The mounting part 320 may include a mounting surface 321. The mounting surface 321 may be arranged on a side of the housing 310. For example, the mounting surface 321 may refer to a surface formed in a concave groove shape toward the inside of the cleaner station 300 on the first outer wall surface 312a. That is, the mounting surface 321 may refer to a surface formed by forming a single unit with the first outer wall surface 312a.
The cleaner 200 may be mounted on the mounting surface 321. For example, the mounting surface 321 may be in contact with the lower surface of the dust bin 220 and the battery housing 230 of the cleaner 200. Here, the lower surface may mean a surface facing the ground when a user uses the cleaner 200 or places it on the ground.
For example, the angle formed by the mounting surface 321 with the ground may be a right angle. Through this, the space of the cleaner station 300 can be minimized when the cleaner 200 is mounted to the mounting surface 321.
As another example, the mounting surface 321 may be arranged to be inclined at a predetermined angle with the ground. Through this, when the cleaner 200 is coupled to the mounting surface 321, the cleaner station 300 may be stably supported.
A dust passage hole 321a may be formed in the mounting surface 321 so that air from the outside of the housing 310 may be introduced into the inside. The dust passage hole 321a may be formed in a hole shape corresponding to the shape of the dust bin 220 so that dust in the dust bin 220 may be introduced into the dust collection part 500. The dust passage hole 321a may be formed corresponding to the shape of the discharge cover 222 of the dust bin 220. The dust passage hole 321a may be formed to communicate with the flow path 380 described later (see FIG. 8).
The mounting part 320 may include a dustbin guide surface 322. The dust bin guide surface 322 may be arranged on the first outer wall surface 312a. The dust bin guide surface 322 may be connected to the first outer wall surface 312a. In addition, the dust bin guide surface 322 may be connected to the mounting surface 321.
The dust bin guide surface 322 may be formed in a shape corresponding to the outer surface of the dust bin 220. The front outer surface of the dust bin 220 may be connected to the dust bin guide surface 322. Through this, the convenience of the cleaner 200 being connected to the mounting surface 321 may be provided.
Meanwhile, a protrusion moving hole 322a may be formed in the dust bin guide surface 322, and a push protrusion 351, which will be described later, may be linearly moved along the protrusion moving hole 322a (see FIG. 9). In addition, a gear box 355 that accommodates a gear of a cover opening unit 350, which will be described later, may be provided on the lower side of the dust bin guide surface 322 in the gravity direction. At this time, a guide space 322b, in which the push protrusion 351 may be moved, may be formed between the dust bin guide surface 322, the lower side, and the upper side of the gear box 355. In addition, the guide space 322b may be connected to the first flow path 381 through a bypass hole 322c. That is, the protrusion moving hole 322a, the guide space 322b, the bypass hole 322c, and the first flow path 381 can form one flow path. With this configuration, when the dust collector motor 391 is operated while the dust bin 220 is connected to the mounting part 320, there is an advantage in that dust remaining in the dust bin 220 and the dust bin guide surface 322 can be sucked in through the flow path.
The mounting part 320 may include a guide protrusion 323. The guide protrusion 323 may be arranged on the mounting surface 321. The guide protrusion 323 may protrude upward from the mounting surface 321. The guide protrusions 323 may be arranged two apart from each other. The distance between the two guide protrusions 323 that are spaced apart from each other may correspond to the width of the battery housing 230 of the cleaner 200. Through this, the convenience of the cleaner 200 being mounted to the mounting surface 321 may be provided.
The mounting part 320 may include a mounting part lateral wall 324. The mounting part lateral wall 324 may mean a wall surface arranged on both lateral surfaces of the mounting surface 321 and may be vertically connected to the mounting surface 321. The mounting part lateral wall 324 can be connected to the first outer wall surface 312a. In addition, the mounting part lateral wall 324 can form a surface connected to the dust bin guide surface 322. Through this, the cleaner 200 can be stably accommodated.
The mounting part 320 may include a mounting sensor. The mounting sensor may detect whether the cleaner 200 is mounting to the mounting part 320.
The mounting sensor may also include a contact sensor. As an example, the mounting sensor may include a micro switch. At this time, the mounting sensor may be placed on the guide protrusion 323. Accordingly, when the battery housing 230 or the battery 240 of the cleaner 200 is coupled between a pair of guide protrusions 323, it comes into contact with the mounting sensor, and the mounting sensor may detect that the cleaner 200 is coupled.
Meanwhile, the mounting sensor may also include a non-contact sensor. For example, the mounting sensor may include an infrared sensor (IR sensor). At this time, the mounting sensor may be placed on the mounting part lateral wall 324. Accordingly, when the dust bin 220 or the cleaner body 210 of the cleaner 200 passes the mounting lateral wall 324 and reaches the mounting surface 321, the mounting sensor may detect the presence of the dust bin 220 or the cleaner body 210.
When the cleaner 200 is connected to the cleaner station 300, the mounting sensor may face the dust bin 220 or battery housing 230 of the cleaner 200.
The mounting sensor may be a means for determining whether the cleaner 200 is connected along with the power being supplied to the battery 240 of the cleaner 200).
The mounting part 320 may include a suction port guide surface 326. The suction port guide surface 326 may be arranged on the first outer wall surface 312a. The suction port guide surface 326 may be connected to the dust bin guide surface 322. The suction port 212 may be coupled to the suction port guide surface 326. The shape of the suction port guide surface 326 may be formed in a shape corresponding to the shape of the suction port 212.
The mounting part 320 may further include a fixing member introduction hole 327. The fixed member introduction hole 327 may be formed in a long hole shape along the mounting part lateral wall 324 so that the fixed member 331 may be introduced.
With this configuration, when a user mounts the cleaner 200 to the mounting part 320 of the cleaner station 300, the cleaner body 210 of the cleaner 200 can be stably placed on the mounting part 320 by the dust bin guide surface 322, the guide protrusion 323, and the suction port guide surface 326. Through this, the convenience of mounting the dust bin 220 and the battery housing 230 of the cleaner 200 to the mounting surface 321 can be provided.
Meanwhile, the cleaner station 300 may further include a charging terminal 328. The charging terminal 328 may be placed in the mounting part 320. The charging terminal 328 may be electrically connected to the cleaner 200 coupled to the mounting part 320. The charging terminal 328 may supply power to the battery of the cleaner 200 coupled to the mounting part 320.
In addition, the cleaner station 300 may further include a side door. The side door may be placed in the housing 310. The side door may selectively expose the dust collection part 500 to the outside. This allows the user to easily remove the dust collection part 500 from the cleaner station 300.
FIG. 6 is a view to describe a fixing unit of a cleaner station according to one embodiment.
Referring to FIG. 6, the cleaner station 300 according to the present disclosure may include a fixing unit 330. The fixing unit 330 may be disposed on the mounting part lateral wall 324. In addition, the fixing unit 330 may be disposed on a back surface of the mounting surface 321. The fixing unit 330 may be configured to fix the cleaner mounted to the mounting surface 321. Specifically, the fixing unit 330 may be configured to fix the dust bin 220 and the battery housing of the cleaner 220 that are mounted to the mounting surface 321.
The fixing unit 330 may include a fixing member 331 configured to fix the dust bin 220 and the housing 230, which are provided in the cleaner 200, and a fixing unit motor 780 configured to drive the fixing member 331. The fixing unit 330 may further include a fixing unit link 335 configured to transmit the power of the fixing unit motor 780 to the fixing member 331.
The fixing member 331 may be provided on the mounting part lateral wall 324 and configured to reciprocate on the mounting part lateral wall 324 to fix the dust bin 220. Specifically, the fixing member 331 may be disposed inside the fixing member introduction hole 327.
The fixing member 331 may be provided on each of the both sides of the mounting part 320. As one example, the fixing members 331 can be arranged in pairs symmetrically centered on the mounting surface 321.
The fixing unit motor 780 may provide power to move the fixing member 331.
The fixing unit link 335 may be configured to covert the rotational power of the fixing unit motor 780 into the reciprocating movement of the fixing member 331.
The fixing sealer 336 may be disposed on the dust bin guide surface 322 to seal the dust bin 220 when the cleaner 200 is mounted. With this configuration, when the dust bin 220 of the cleaner 200 is mounted, the fixing sealer 336 can be pressurized by the weight of the cleaner 200, and the dust bin 220 and the dust bin guide surface 322 can be sealed.
The fixing sealer 336 can be placed on an imaginary extension of the fixing member 331. With this configuration, when the fixing unit motor 780 is operated and the fixing member 331 pressurizes the dust bin 220, the circumference of the dust bin 220 at the same height can be sealed.
According to an embodiment, the fixing sealer 336 may be placed on the dust bin guide surface 322 in a bent line shape corresponding to the arrangement of the cover opening unit 350 described later.
Therefore, when the cleaner body 210 of the cleaner 200 is placed in the mounting part 320, the fixing unit 330 can fix the cleaner body 210 of the cleaner 200. Specifically, when the mounting sensor 325 detects that the cleaner body 210 of the cleaner 200 is coupled with the mounting part 320 of the cleaner station 300, the fixing unit motor 780 can move the fixing member 331 to fix the cleaner body 210 of the cleaner 200.
This can improve the suction power of the cleaner by preventing residual dust from remaining in the dust bin. In addition, it can eliminate the unpleasant odor caused by residual dust by preventing residual dust from remaining in the dust bin.
FIGS. 7 and 8 are views to describe the relationship of the cleaner and the door unit in the cleaner station according to an embodiment. FIG. 7 is a view showing a state where a door closed a dust passage hole. FIG. 8 is a view showing a state where the door has opened the dust passage hole.
Referring to FIGS. 7 and 8, the cleaner station 300 according to the present disclosure may include a door unit 340. The door unit 340 may be configured to open and close the dust passage hole 321a.

The door 341 may be hingedly coupled to the mounting surface 321, and configured to open and close the dust passage hole 321a. the door 231
The door body 341a may be formed in a shape that can block the dust passage hole 321a. For example, the door body 341a may be formed in a shape similar to a circular plate.
Based on the state in which the door body 341a blocks the dust passage hole 321a, a hinge unit may be arranged on the upper side of the door body 341a, and an arm coupling portion 341b may be arranged on the lower side of the door body 341a.
The door body 341a may be formed in a shape that can seal the dust passage hole 321a. For example, the outer surface of the door body 341a exposed to the outside of the cleaner station 300 is formed to have a diameter corresponding to the diameter of the dust passage hole 321a, and the inner surface disposed inside the cleaner station 300 is formed to have a diameter larger than the diameter of the dust passage hole 321a. In addition, a step may be generated between the outer surface and the inner surface. Meanwhile, at least one reinforcing rib may be formed protruding on the inner surface to connect the hinge unit and the arm coupling portion 341b and to strengthen the supporting force of the door body 341a.
The hinge unit may be a means for hinge-connecting the door 341 to the mounting surface 321. The hinge unit may be arranged at the upper end of the door body 341a and may be connected to the mounting surface 321.
The arm coupling portion 341b may be a means by which the door arm 343 is rotatably coupled. The arm coupling portion 341b is arranged on the lower side of the door body 341a, is rotatably coupled with the door body 341a, and the door arm 343 may be rotatably coupled.
With this configuration, when the door arm 343 pulls the door body 341a while the door 341 is closing the dust passage hole 321a, the door body 341a rotates toward the inside of the cleaner station 300 with the hinge unit as an axis, and the dust passage hole 321a can be opened. Meanwhile, when the door arm 343 pushes the door body 341a while the dust passage hole 321a is open, the door body 341a rotates toward the outside of the cleaner station 300 with the hinge unit 341b as an axis, and the dust passage hole 321a can be blocked.
Meanwhile, when the cleaner 200 is coupled to the cleaner station 300 and the discharge cover 215 is separated from the dust bin body 210, the door 341 can come into contact with the discharge cover 215. And, as the door 341 rotates, the discharge cover 215 can rotate in conjunction with the door 341.
The door motor 342 can provide power to rotate the door 341. Specifically, the door motor 342 can rotate the door arm 343 in a forward or reverse direction. Here, the forward direction may mean a direction in which the door arm 343 pulls the door 341. Accordingly, when the door arm 343 rotates in a forward direction, the dust passage hole 321a can be opened. In addition, the reverse direction may mean a direction in which the door arm 343 pushes the door 341. Accordingly, when the door arm 343 rotates in a reverse direction, the dust passage hole 321a can be at least partially closed. The forward direction may be a direction opposite to the reverse direction.
The door arm 343 connects the door 341 and the door motor 342, and can open and close the door 341 using the power generated from 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 with a door motor 342. The first door arm 343a may be rotated by the power of the door motor 342. The other end of the first door arm 343a may be rotatably coupled with the second door arm 343b. The first door arm 343a may transmit power transmitted from the door motor 342 to the second door arm 343b. One end of the second door arm 343b may be coupled with the first door arm 343a. The other end of the second door arm 343b may be coupled with the door 341. The second door arm 343b can open or close the dust passage hole 321a by pushing or pulling the door 341.
The door unit 340 can be opened together with the discharge cover 222 of the cleaner 200 when it is opened. Also, when the door unit 340 is closed, the discharge cover 222 of the cleaner 200 can be closed together with it.
When the dust in the dust bin 220 of the cleaner 200 is removed, the door motor 342 can connect the discharge cover 222 to the dust bin body 221 by rotating the door 341. Specifically, the door motor 342 rotates the door 341 by rotating the door 341 relative to the hinge unit 341b, and the door 141 that rotates relative to the hinge unit 341b can push the discharge cover 222 toward the dust bin body 221.
FIG. 9 is a view to describe the relationship between the vacuum cleaner and a cover opening unit.
Referring to FIG. 9, the cleaner station 300 of the present invention may include a cover opening unit 350. The cover opening unit 350 is disposed at the mounting part 320 and may open the discharge cover 222 of the cleaner 200.

The push protrusion 351 can move linearly back and forth to press the mounting lever 222c. Specifically, the push protrusion 351 can be coupled to the gear box 355 so that the linear movement can be guided. The push protrusion 351 can be coupled to a cover opening gear 353 so that it can move together with the movement of the cover opening gear 353.
The cover opening motor 352 can provide power to move the push protrusion 351. Specifically, the cover opening motor 352 can rotate the motor shaft in a forward or reverse direction. Here, the forward direction may mean the direction in which the push protrusion 351 presses the mounting lever 222c. In addition, the reverse direction may mean the direction in which the push protrusion 351 that presses the mounting lever 222c returns to the original position. The forward direction may be the opposite direction to the reverse direction.
The cover opening gear 353 is coupled with the cover opening motor 352 and can move the push protrusion 351 using the power of the cover opening motor 352. Specifically, the cover opening gear 353 can be accommodated inside the gear box 355. The driving gear 353a of the cover opening gear 353 can be coupled with the motor shaft of the cover opening motor 352 to receive power. The driven gear 353b of the cover opening gear 353 can be coupled with the push protrusion 351 to move the push protrusion 351. For example, the driven gear 353b is provided in the form of a rack gear to mesh with the driving gear 353a and can receive power from the driving gear 353a.
At this time, the discharge cover 222 may be provided with a torsion spring 222d.

Hereinafter, the flow path extending from the mounting part 320 to the dust collection part 500 is referred to as the first flow path 381. The dust collection part 500 where dust is collected is connected and arranged on the lower side of the first flow path 381.
The cleaner station 300 may further include a chamber part 360.
The chamber part 360 is placed in the housing 310 and a dust collection part accommodating space 360a is formed to receive the dust collection part 500.
At this time, the dust collection part 500 may be detachably provided in the chamber part 360. The chamber part 360 may be configured to be detachably provided in the housing 310 or may be configured to be formed integrally with the housing 310. The detailed structure of the chamber part 360 is described in FIG. 11 and below.
The cleaner station 300 may include a flow path 380.
The flow path 380 is defined as a passage through which air and foreign substances that have escaped the dust bin 220 of the cleaner 200 flow. The flow path 380 may include a first flow path 381 connecting the dust bin 220 and the dust collection part 500 and a second flow path 382 connecting the dust collection part 500 and the dust collection motor 391.
The first flow path 381 may be arranged on the rear side of the mounting surface 321. The first flow path 381 may refer to a space formed between the dust bin 220 of the cleaner 200 and the dust collection art 500 so that air can flow. For example, the first flow path 381 may be a space formed by being surrounded by a structure. For example, the first flow path 381 may be an internal space of a hollow tube.
The first flow path 381 may include a first region 381a that communicates with the internal space of the dust bin 220 when the cleaner 200 is coupled to the cleaner station 300 and the dust passage hole 321a is opened, and a second region 381b that communicates the first region 381a and the dust collection part 500. (See FIG. 8)
Therefore, when the dust collection motor 391 is operated, dust in the dust bin 220 of the cleaner 200 can flow to the dust collection part 500 through the first flow path 381.
The second flow path 382 can connect the dust collection part 500 and the dust suction module 390. That is, air from which dust is separated while passing through the dust collection part 500 can be guided to the dust collection motor 391 through the second flow path 382.
The second flow path 382 may refer to a space formed between the dust collection part 500 and the dust suction module 390 to allow air to flow. The second flow path 382 may be formed by being surrounded by a structure.
In an embodiment where the dust collection part 500 is the first dust collection part 510, a portion of the second flow path 382 may be formed inside the first dust collection part 510. The portion may be referred to as the discharge flow path 518. The discharge flow path 518 may be arranged on the front side of the dust collection part body 511. (See FIGS. 24 and 26)
The cleaner station 300 may include a dust suction module 390.
Referring back to FIG. 10, the dust suction module 390 may include a dust collection motor 391. The dust collection motor 391 may be placed at the bottom of the dust collection part 500. The dust collection motor 391 may generate suction force in the flow path 380. Through this, suction force capable of sucking dust into the dust bin 220 of the cleaner 200 is provided.
The dust suction module 390 may further include a HEPA filter (not shown). The HEPA filter may be placed at the rear end (based on the air flow path) of the dust collection motor 391. As a result, clean air is discharged to the outside of the housing 310.
Meanwhile, although not shown in FIG. 10, the fixing unit 330 and the door unit 340 are arranged adjacent to the mounting part 320, which has already been described with reference to FIGS. 6 to 8.
The cleaner station 300 may further include the dust collection part 500.
FIG. 11 is a perspective view showing a chamber part and a dust collection part configured to be coupled to the chamber part.
The dust collection part 500 can be detachably connected to the chamber part 360. The dust collection part 500 is provided with a dust receiving space so that dust sucked in from inside the dust bin 220 by the dust collection motor 391 can be collected.
Meanwhile, the dust collection part 500 according to the embodiment of the present invention can be a first dust collection part 510 in the form of a bucket with a fixed size of the dust receiving space.
The first dust collection part 510 has a 'bucket' shape, so it is easy to clean the inside, and it has the advantage of being able to be used semi-permanently if only the dust contained is removed. However, the dust removal and cleaning, which are tasks that must be performed separately, may be inconvenient for the user.
Alternatively, the dust collection part 500 according to the embodiment of the present invention may be a second dust collection part 520 in the form of an envelope in which the size of the dust containing space is variable.
The second dust collection part 520 is usually made of a breathable material that allows air to escape but not dust to escape. The second dust collection part 520 has a problem in that it cannot be cleaned inside even if the dust it contains is removed, so it must be purchased and replaced periodically. However, it has a simple structure and can be thrown away in a trash can as a whole without having to remove dust or clean its inside separately, so it has an advantage in terms of user convenience.
The cleaner station 300 according to an embodiment of the present invention can operate regardless of which of the two types of dust collection parts 510 and 520 is accommodated in the dust collection part accommodating space 360a of the chamber part 360. In other words, the two types of dust collection parts 510, 520 are compatible.
The user can select the dust collection parts 510 and 520 to be used by considering the advantages and disadvantages of each dust collection part 510 and 520 described above and his/her own preference.
The advantage of compatibility is not limited to the user's preference area. For example, there is also an advantage in that a user who prefers the first dust collection part 510 can temporarily use the second dust collection part 520 as an alternative during the process of washing and drying the first dust collection part 510.
Below, various features provided in the chamber part 360 to enable different types of dust collection parts 510 and 520 to be compatible are described.
FIG. 12 is a cross-sectional view of the chamber part viewed from a lateral surface according to one embodiment. FIG. 13 is an enlarged cross-sectional view of an upper area of the lateral surface of the chamber part according to one embodiment. FIG. 14 is a front view of the chamber part according to one embodiment. FIG. 15 is a perspective view showing the inner structure of the chamber part according to one embodiment. FIG. 16 is a cross-sectional view showing a compression drive unit according to one embodiment.
First, referring to FIG. 11, the chamber part 360 may include a chamber body 361.
The chamber body 361 may be configured to define the exterior of the dust collection part accommodating space 360a. The dust collection part accommodating space 360a may be formed in a shape similar to a hexahedral.
One side of the chamber body 361 may be open. The open side of the chamber body 361 may be forward. The open side of the chamber body 361 may be closed by the housing cover 370.
One side of the housing cover 370 can 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. Conversely, when the other side of the housing cover 370 rotates toward the housing 310, one side of the chamber body 361 can be closed.
The dust collection part accommodating space 360a formed by the chamber body 361 can be formed so that the cross-sectional area of the front end is wider than the cross-sectional area of the rear end.
More specifically, referring to FIG. 12, a virtual plane p1 connecting the front upper end and the rear upper end of the chamber body 361 may have a rearward-downward slope.
A virtual plane p2 connecting the front lower end and the rear lower end of the chamber body 361 may have a rearward-upward slope.
The upper side of the chamber body 361 has a downward slope as it goes toward the rear, and the lower side has an upward slope as it goes toward the rear, so that the dust collection part accommodating space 360a has a wider cross-sectional area at the front end than at the rear end.
Through this structure, there is an advantage in that the fixed type of first dust collection part 510 can be easily inserted into the dust collection part accommodating space 360a.
An air inlet 3611 may be provided in the chamber body 361.
The air inlet 3611 allows air introduced through the first flow path 381 to pass through. The air inlet 3611 may be provided on the upper surface of the chamber body 361. Alternatively, the air inlet 3611 may be provided at an end of a hollow tube integrally connected to the chamber body 361.
The air inlet 3611 is arranged to overlap the dust inlet of the dust collection part 500 described later, vertically. That is, air and dust passing through the first flow path 381 pass through the air inlet 3611 and the dust inlet in sequence and are introduced into the dust receiving space of the dust collection part 500.
An inlet sealing member 367 may be arranged between the air inlet 3611 and the first flow path 381. The inlet sealing member 367 seals between the air inlet 3611 and the first flow path 381 to prevent air and dust from leaking out to a space other than the chamber body 361. The inlet sealing member 367 may be arranged to surround the perimeter of the air inlet 3611.
The chamber body 361 has a generally downwardly inclined structure from the front upper end to the rear upper end as described above, and a portion of the upper surface of the chamber body 361 may include an inclined surface formed with a rearward-downward slope at a predetermined angle.
The air inlet 3611 formed on the upper portion of the chamber body 361 may also have its open cross-section formed to be downwardly inclined from the front to the rear.
An air outlet 3612 may be provided in the chamber body 361.
The air outlet 3612 allows air filtered from dust to pass through the dust collection part 500. The air outlet 3612 may be provided at the bottom of the chamber body 361. The air outlet 3612 may be provided at the bottom of the mounting wall of the filter securing portion 365 described later. (See FIG. 20)
The air outlet 3612 is connected to the dust suction module 390. That is, air passing through the air outlet 3612 can be finally discharged to the outside of the housing through the dust suction module 390.
Referring to FIGS. 11 and 15, the chamber part 360 may include a compression drive unit 362.
The compression drive unit 362 may be configured to generate power for rotating a compression rotation unit 515 configured to compress dust collected in the first dust collection part 510. The compression rotation unit 515 will be described later.
The compression drive unit 362 may be arranged at the lower part of the chamber body 361. More specifically, the compression drive unit 362 may be arranged at the outer lower part of the chamber body 361.
Referring further to FIG. 16, the detailed configuration of the compression drive unit 362 is described as follows.
The compression drive unit 362 may include a compression motor 3622. The compression motor 3622 may be arranged outside the dust collection part accommodating space 360a. That is, the compression motor 3622 may be arranged outside the chamber body 361.
The compression motor 3622 generates power for the compression rotation unit 515 to rotate. The compression motor 3622 is provided with a motor capable of forward and reverse rotation. In other words, a motor capable of bidirectional rotation is used as the compression motor 3622.
In this way, in order to enable the forward and reverse rotation of the compression motor 3622, a synchronous motor may be used as the compression motor 3622. This synchronous motor is configured to enable the forward and reverse rotation by the motor itself, and when the force applied to the compression motor 3622 when the compression motor 3622 rotates in one direction exceeds a set value, the rotation of the compression motor 3622 is converted to the other direction.
At this time, the force applied to the compression motor 3622 is a resistance force (or torque) generated when the rotary plate 5153 described later presses another member (i.e., fixed plate 5152 or collected dust), and when the resistance force reaches the set value, the rotation direction of the compression motor 3622 is configured to be converted.
Since the technology for synchronous motors other than the above is generally known in the motor technology field, a detailed description thereof will be omitted.
The compression drive unit 362 may further include a drive gear 3621.
The drive gear 3621 is rotated by the power of the compression motor 3622. For this purpose, the drive gear 3621 may be connected to the motor shaft of the compression motor 3622. The drive gear 3621 may be coupled to the upper side of the compression motor 3622.
The driving gear 3621 may be placed outside the dust collection part accommodating space 360a. That is, the driving gear 3621 may be placed outside the chamber body 361.
At this time, a portion of the lower surface of the chamber body 361 may protrude upward to form a driving gear accommodating portion 3613. (See FIG. 15)
A gear passage hole 3613a is formed at the bottom of the chamber body 361 to expose at least a part of the driving gear 3621 toward the inside of the dust collection part accommodating space 360a. More specifically, the gear passage hole 3613a may be formed by penetrating the side of the driving gear accommodating portion 3613. The gear teeth 3621c of the driving gear 3621 may be exposed through the gear passage hole 3613a. (See FIG. 15)
Meanwhile, since the driving gear 3621 and the compression motor 3622 are arranged on the outside of the dust collection part accommodating space 360a, considering that the dust collection part accommodating space 360a is a space that is periodically opened, there is an effect of preventing the driving gear 3621 and the compression motor 3622 from being exposed to contamination.
The drive gear 3621 can transmit rotational power to the compression rotation unit 515.
The compression rotation unit 515 is a concept including one or more components that rotate to compress the dust collected in the dust accommodating space of the first dust collection part 510.
The detailed structure will be described later, but the rotary plate 5153 included in the compression rotation unit 515 rotates to collect dust. The rotary plate 5153 rotates to approach the fixed plate 5152 fixedly arranged on one side of the first dust collection part 510, thereby pressurizing and compressing the dust collected between the fixed plate 5152.
The first dust collection part 510 may include a transmission gear 514.
The transmission gear 514 is a configuration that is coupled with the compression rotation unit 515, and is arranged between the compression drive unit 362 and the compression rotation unit 515 to transmit rotational power.
More specifically, the transmission gear 514 may be arranged on the lower outer side of the first dust collection part 510. When the first dust collection part 510 is inserted into the dust collection accommodating 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 passage hole 3613a.
As a result, the rotational power generated by the compression motor 3622 may be transmitted to the compression rotation unit 515 through the driving gear 3621 and the transmission gear 514.
Meanwhile, since the drive gear 3621 is accommodated in the drive gear accommodating portion 3613, and the drive gear accommodating portion 3613 is formed with a structure that protrudes upward from the lowest end surface of the dust collection part accommodating space 360a, the user can easily engage the transmission gear 514 and the drive gear 3621 by simply pushing the first dust collection part 510 horizontally.
Referring to FIG. 14 and FIG. 15, the chamber part 360 may include a rail unit 363.
The rail unit 363 may be arranged on the upper part of the chamber body 361. More specifically, the rail unit 363 may be arranged on the inner upper part of the chamber body 361.
The rail unit 363 is configured such that at least a part of the second dust collection part 520 is fitted and the second dust collection part 520 may slide along the rail unit 363. The second dust collection part 520 may be supported in a state separated from the lower surface of the chamber body 361 and in a state suspended from the rail unit 363.
As described above, the second dust collection part 520 is a dust back-type dust collection part 500 in which the shape of the dust accommodating space is variable.
At this time, the dust bag 521 included in the second dust collection part 520 is expanded by the suction drive of the dust collection motor 391, and dust can be introduced from the first flow path 381 into the interior of the dust bag 521 by the negative pressure formed as the dust bag 521 is expanded.
In the embodiment of the present invention, the dust bag 521, which is a component of the second dust collection part 520, is made of a breathable material. That is, it is made of a material that prevents dust of a certain size or larger from escaping, but allows air to escape. Therefore, as long as the suction drive of the dust collection motor 391 continues, the dust is also continuously sucked into the interior of the dust bag 521.
If there is no gap between the lowest end of the dust bag 521 and the inner bottom surface of the chamber body 361 when the dust bag 521 is inflated to the maximum, the dust suction power is reduced. Therefore, in order to evenly transmit the suction power to the dust bag 521, it is preferable that the dust bag 521 be inflated to the maximum and be inflated to the bottom surface of the chamber body 361 by a predetermined distance.
In an embodiment of the present invention, the rail unit 363 having a structure that supports the second dust collection art 520 by separating it from the bottom surface of the chamber body 361 is provided, thereby enabling compatibility between the first dust collection part 510 and the second dust collection part 520.
The rail unit 363 may include a rail body 3631.
Referring to FIGS. 13 to 15, the rail body 3631 may form a space in which the second dust collection part 520 slides. The rail body 3631 may be formed in a form extending from the front to the rear of the chamber body 361. The rail body 3631 may be arranged on the left and right sides, respectively. The rail body 3631 may be formed in a left-right symmetrical structure.
The rail body 3631 is open toward the center of the chamber body 361 and may be provided in a shape similar to a 'U' that is rotated 90 degrees. From another perspective, the rail body 3631 may be provided in a shape similar to the Korean consonant '' with the rail body 3631 positioned on the left as the standard.
However, the shape of the rail body 3631 described above is an example, and the shape of the rail body 3631 may be changed to an appropriate structure that can support the second dust collection part 520 on the upper side of the chamber body 361.
The upper surface of the rail body 3631 arranged on the upper surface of the chamber body 361 may be configured as an inclined surface, similar to the upper surface of the chamber body 361. In contrast, the lower surface of the rail body 3631 may be formed to be parallel to the ground. (See FIG. 13)
Hereinafter, the detailed configuration of the rail unit 363 will be further described with reference to FIG. 17 and FIG. 18.
FIG. 17 is an enlarged view of "A" shown in FIG. 15. FIG. 18 is a cross-sectional view along C-C' of FIG. 17.
Referring to FIG. 17 and FIG. 18 along with FIG. 15, the rail unit 363 may further include an interference protrusion 3632.
The interference protrusion 3632 may be positioned at a first position Position 1 that interferes with the housing cover 370 at the front of the rail body 3631.
More specifically, the first position may mean 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 mean a position that shields the insertion progression path of some components included in the first dust collection part 510 and the second dust collection part 520 when the first dust collection part 510 or the second dusts collection part 520 is inserted into the dust collection part accommodating space 360a.
Here, some configurations that shield the insertion path may be, in the case of the first dust collection part 510, an outer plate 522 to be described later. (See FIG. 31) In the case of the second dust collection part 520, some configurations may be ribs 5161c protruding from the body cover 516. (See FIG. 23)
The interference protrusion 3632 may be moved to a second position Position 2 where interference with the housing cover 370 is avoided by contact with the first dust collection part 510 (specifically, the outer plate 522) or the second dust collection part 520 (specifically, the rib 5161c).
Meanwhile, the cover protrusion 371 may be formed protruding on the housing cover 370.
The cover protrusion 371 may be positioned at a position where it comes into contact with the aforementioned interference protrusion 3632 when the housing cover 370 rotates to close the open side of the chamber body 361. (See FIG. 15) That is, the interference protrusion 3632 interfering with the housing cover 370 means that the interference protrusion 3632 and the cover protrusion 371 come into contact with each other.
The rail portion 363 may further include a protrusion guide 3633.
Continuing, referring to FIG. 17 and FIG. 18, the protrusion guide 3633 can be combined with the interference protrusion 3632. The protrusion guide 3633 can guide the movement of the interference protrusion 3632.
More specifically, the protrusion guide 3633 has a space formed inside in which the interference protrusion 3632 is accommodated, and a hooking protrusion 3662 formed inside the space to engage with a hook 3632a formed at the end of the interference protrusion 3632 can be formed.
The interference protrusion 3632 can be placed at the first position while the hook 3632a and the hooking protrusion 3662 are in contact with each other. As the interference projection 3632 moves from the first position to the second position, the contact between the hook 3632a and the hooking protrusion 3662 can be released. (See FIG. 19)
The rail unit 363 may further include a restoring member 3634.
Referring to FIG. 18, the restoring member 3634 may be coupled to a space formed inside 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 moving direction md1, and the direction opposite to the first moving direction is defined as the second moving direction md2. The restoring member 3634 may provide elastic force to the interference protrusion 3632 toward the second moving direction, and the interference protrusion 3632 may be moved in the second moving direction until the hook 3632a and the hooking protrusion 3662 come into contact with each other by the restoring member 3634.
Referring to FIG. 19, the operation of the interference protrusion 3632 in the case where the dust collection part 500 is inserted and not inserted into the dust collection part accommodating space 360a is described.
FIG. 19 is a view to describe the movement of an interference protrusion and the position relationship with a housing cover.
The left drawing of FIG. 19 shows a situation in which the cover protrusion 371 and the interference protrusion 3632 are in contact with each other when the interference protrusion 3632 is in the first position. At this time, the direction in which force is applied to the interference protrusion 3632 as the cover protrusion 371 comes into contact with the interference protrusion 3632 and the direction in which the interference protrusion 3632 moves from the first position to the second position can form a predetermined angle.
The force does not have a component in the direction of moving the interference protrusion 3632 from the first position to the second position. Therefore, the interference protrusion 3632 cannot be moved by the force of the cover protrusion 371, and since the interference protrusion 3632 prevents the housing cover 370 from rotating any further, the chamber body 361 cannot be closed.
The right drawing of FIG. 19 shows a case where the interference protrusion 3632 is in the second position, and the cover protrusion 371 does not come into contact with the interference protrusion 3632. The housing cover 370 can rotate until it completely closes the open side of the chamber body 361.
At this time, the first dust collection part 510 or the second dust collection part 520 moves the interference protrusion 3632 from the first position to the second position. When the first dust collection part 510 or the second dust collection part 520 is inserted into the dust collection part accommodating space 360a, a part of the first dust collection part 510 or the second dust collection part 520 may push the interference protrusion 3632 to the second position.
The interference protrusion 3632 may be provided with an inclined portion 3632c that comes into contact with some components of the dust collection part 500.
Referring to FIG. 15, the chamber part 360 may further include a filter mounting portion 365.
The filter mounting portion 365 may be placed at the bottom of the chamber body 361. The filter mounting portion 365 may mean a filter mounting space in which a pre-filter module 470 that filters air passing through the dust collection part 500 is detachably coupled, and a mounting wall surrounding the filter mounting space.
At this time, the air outlet 3612 described above is formed at the bottom of the mounting wall. From another perspective, the air outlet 3612 is formed at the bottom of the filter mounting space.
If the pre-filter module 470 is coupled to the filter mounting portion 365, air that exits the dust collection part 500 and heads to the air outlet 3612 passes through the pre-filter module 470 and then moves to the dust suction module 390 via the air outlet 3612.
If the pre-filter module 470 is not attached to the filter mounting portion 365, the air that has exited the dust collection part 500 passes through the air outlet 3612 and moves to the dust suction module 390.
FIG. 20 is a view of a prefilter module divided into component units and developed according to one embodiment.
Referring to FIG. 20, the prefilter module 470 may include a filter case 471and 472 and a filter 473 and 474.
The filter case 471 and 472 may be composed of a case upper portion 471 and a case lower portion 472, and the case upper portion 471 and the case lower portion 472 may be connected via a hinge. When the hinge is rotated about an axis, the space inside the case may be opened and closed.
An air inlet 4711 is formed in the case upper portion 471.
The air inlet 4711 may be formed on the upper surface of the case upper portion 471 in a shape corresponding to the shape of the discharge path 518 of the first dust collection part 510 to be described later. Air that has exited the discharge path 518 of the first dust collection part 510 may be introduced into the interior of the filter case 471 and 472 through the air inlet 4711. Air that has exited the dust bag 521 of the second dust collection part 520 may be introduced into the interior of the filter case 471 and 472 through the air inlet 4711.
An air outlet 4721 is formed in the lower portion of the case 472.
The air outlet 4721 may be formed by a plurality of holes penetrating the lower surface of the case lower portion 472. The air outlets 4721 may be arranged to be distributed over the entire lower surface area of the case lower portion 472 so that air can evenly pass through the filter.
At least one filter 473 and 474 may be accommodated in the internal space formed by the case upper portion 471 and the case lower portion 472. The filter 473 and 474 may include a first filter 473 made of a sponge material. The filter 473 and 474 may include a second filter 474 made of a non-woven material.
A pressing protrusion 4712 may be formed to protrude on one side of the filter case 471 and 472.
The pressing protrusion 4712 is configured to press the filter detection protrusion 366 to be described later when the pre-filter module 470 is mounted on the filter mounting portion 365. The pressing protrusion 4712 may be formed in the form of a rib protruding from one surface of the upper portion 471 or the lower portion 472 of the case. (See FIG. 22)
Referring to FIG. 15, the chamber part 360 may further include the filter detection protrusion 366.
The filter detection protrusion 366 may be arranged at the bottom of the chamber body 361. More specifically, the filter detection protrusion 366 may be arranged adjacent to the mounting wall of the filter mounting portion 365.
One side of the filter detection protrusion 366 may be maintained in a state of protruding toward the dust collection part accommodating space 360a when the pre-filter module 470 is not coupled to the filter mounting portion 365.
For this purpose, although not shown, a pressure means for applying force in the direction of protruding the one side may be coupled to the filter detection protrusion 366. For example, the pressure means may be an elastic body such as a spring.
In this way, when one side of the filter detection protrusion 366 protrudes toward the dust collection part accommodating space 360a, the rear side of the first dust collection part 510 and the filter detection protrusion 366 interfere with each other, making it impossible to completely insert the first dust collection part 510 into the dust collection part accommodating space 360a.
In contrast, since the second dust collection part 520 is kept spaced apart from the bottom of the chamber body 361 even when the dust bag 521 is fully inflated, the insertion of the second dust collection part 520 is not hindered by the filter detection protrusion 366.
With this configuration, the user cannot use the first dust collection part 510 without mounting the pre-filter module 470 on the filter mounting portion 365. If the user forgets to detach the pre-filter module 470 and then inserts the first dust collection part 510 into the chamber body 361, it will not be fully inserted because it will be caught by the filter detection protrusion 366. After mounting the pre-filter module 470 on the filter mounting portion 365, the user can insert the first dust collection part 510 into the chamber body 361 again.
Meanwhile, when the pre-filter module 470 is connected to the filter mounting portion 365, one side of the filter detection protrusion 366 may be pressed by the pre-filter module 470. At this time, the filter detection protrusion 366 can be moved in a direction to avoid interference with the first dust collection part 510.
FIG. 21 is an enlarged view of "B" shown in FIG. 15 to describe the movement of a filter detection protrusion based on whether a prefilter module is mounted or not. FIG. 22 is a cross-sectional view along D-D' of FIG. 21.
Referring to FIGS. 21 and 22, the filter detection protrusion 366 may include a protrusion body 3661 and a hooking protrusion 3662 formed protruding on the outer surface of the protrusion body 3661. At this time, a space in which the pressurizing means (not shown) described above is arranged may be formed inside the protrusion body 3661.
Referring to the left drawing of FIG. 21 and the left drawing of FIG. 22, a state in which a pre-filter module 470 is not mounted on the filter mounting portion 365 is shown. The filter detection protrusion 366 maintains a state in which one side protrudes toward the dust collection part accommodating space 360a.
The right drawing of FIG. 21 shows a state in which a pre-filter module 470 is mounted on the filter mounting portion 365. Referring to the right drawing of FIG. 22, the filter detection protrusion 366 is pressed against the hooking protrusion 3662 by the pressing protrusion 4712.
At this time, as in the embodiment of FIG. 22, the pressing protrusion 4712 may be formed to protrude from one surface of the upper portion of the case 471. As the pre-filter module 470 is mounted on the filter mounting portion 365, the pressing protrusion 4712 may come into contact with the hooking protrusion 3662, and may press downward one side of the filter detection protrusion 366 that is in a protruding state by encroaching on the dust collection part accommodating space 360a.
As a result, the first dust collection part 510 may be completely inserted into the chamber body 361 without interference.
Meanwhile, the necessity of the filter detection protrusion 366 described above is related to the fact that the dust separation means between the first dust collection part 510 and the second dust collection part 520 are different.
The dust separation means of the first dust collection part 510 may include a mesh net 5121 and a cyclone 513.
The dust separation means of the second dust collection part 520 may include a dust bag 521 made of a breathable material.
In the case of the second dust collection part 520, dust particles larger than a certain size structurally cannot pass through the dust bag 521. Since the dust bag 521 can perform the function of a pre-filter by itself, the installation of the pre-filter module 470 is optional for the user and is not essential.
However, in the case of the first dust collection part 510, although fine dust can be largely separated through the dust collection action of the cyclone 513, it is structurally impossible to completely filter fine dust like the dust bag 521 of the first dust collection part 510.
Therefore, in order to prevent fine dust from entering the dust collection motor 391, a pre-filter module 470 must be placed in the path through which air passing through the first dust collection part 510 enters the dust collection motor 391.
The embodiment of the present invention has the effect of drawing the user's attention to the non-installation of the pre-filter module 470 when using the first dust collection part 510.
In addition, the embodiment of the present invention has the effect of reducing the cost of purchasing a filter according to the user's choice by allowing the use of the second dust collection part 520 regardless of whether the pre-filter module 470 is mounted.
Referring to FIG. 13, the chamber part 360 may further include a sterilization module mounting portion 364.
The sterilization module mounting portion 364 may be placed on the upper portion of the chamber body 361. The sterilization module mounting portion 364 may be placed apart from the air inlet 3611. The sterilization module mounting portion 364 may include a sterilization module mounting space formed by bending a portion of the upper surface of the chamber body 361 upward and a mounting wall surrounding the mounting space.
The sterilization module mounting portion 364 may be mounted to the sterilization module 450 that is configured to irradiate ultraviolet light toward the dust collection part accommodating space 360a.
The sterilization module 450 is a configuration provided to sterilize dust captured in the dust collection part 500. The sterilization module 450 may include a light source that emits sterilizing light and a protective panel that is positioned below the light source to protect the light source.
In a possible embodiment, the light source and the protective panel may be mounted on the sterilization module mounting portion 364 in a form accommodated in a separately provided housing. Alternatively, in a possible embodiment, the light source and the protective panel may be mounted on the sterilization module mounting space in a form that is directly accommodated in the sterilization module mounting space.
In this way, the combination form of the sterilization module 450 and the sterilization module mounting portion 364 is not limited to any one embodiment as long as the light source of the sterilization module 450 is arranged to emit sterilizing light toward the dust collection part accommodating space 360a.
Here, the light source may include at least one light-emitting diode (LED) capable of emitting germicidal light having germicidal power capable of removing bacteria. The germicidal light emitted by the light source may have a wavelength that varies depending on the type of the light-emitting diode.
As an example, the light source may be a light-emitting diode that emits ultraviolet light having a UV-C wavelength range. Ultraviolet light is divided into UV-A (315 nm to 400 nm), UV-B (280 nm to 315 nm), and UV-C (200 nm to 280 nm) based on the wavelength, and among these, ultraviolet light in the UV-C range can damage the DNA double helix of microorganisms and inhibit the growth of microorganisms.
Or, as another example, the light source may be a light emitting diode that emits visible light having a wavelength of 405 nm. Blue light having a wavelength of 405 nm has a wavelength in the boundary region between visible light and ultraviolet light, and has been proven to have a sterilizing effect.
The protective panel may be arranged at a predetermined distance from the light source to prevent the light source from being damaged. At this time, the protective panel may be provided with a material that maximizes the transmittance of the light source. As an example, the protective panel may 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, by providing a sterilization module 450 and a sterilization module mounting portion 364, there is an advantage in that the cleaner station 300 can be hygienically managed even when dust sucked from the dust bin 220 of the cleaner 200 is stored in the dust collection part 500 for a long period of time.
In addition, the embodiment of the present invention has an advantage in that the sterilization function can be used regardless of the type of dust collection part 500 selected by the user since the sterilization module mounting portion 364 is placed in the chamber part 360.
Below, the detailed structure of the first dust collection part 510 is described.
FIG. 23 is a perspective view of first dust collection part according to one embodiment. FIG. 24 is a view showing the components of the first dust collection part according to one embodiment that are separated and developed. FIG. 25 is a view showing a dust separation process of cyclone according to one embodiment. FIG. 26 is a cross-sectional view along X-X' of FIG. 23.
Referring to FIGS. 23 to 26, the first dust collection part 510 may include a dust collection part body 511, a dust collection part inner wall 512, and a cyclone (513).
The dust collection part body 511 forms the outer appearance of the dust collection accommodating space. In a possible embodiment, the dust collection part body 511 may have a generally hexahedral shape. In another possible embodiment, the dust collection part body 511 may have a generally cylindrical shape.
The first dust collection part 510 may further include a body cover 516 provided to cover the open upper side of the first dust collection part body.
The shape of the body cover 516 may be formed corresponding to the shape of the rail unit 363.
More specifically, the body cover 516 may include a first cover portion 5161 and a second cover portion 5162.
The upper surface of the first cover portion 5161 may be formed as a slope having a rearward-downward slope. Accordingly, the rear of the first dust collection part 510 may be formed with a lower height to the top and the front may be formed with a higher height to the top.
Meanwhile, as described above, the dust collection part accommodating space 360a formed by the chamber body 361 may be formed with a cross-sectional area of the front end wider than the cross-sectional area of the rear end.
That is, the rear of the first dust collection part 510 where the insertion into the dust collection part accommodating space 360a begins is low in height, and the front end of the dust collection part accommodating space 360a, which is the entrance into which the first dust collection part 510 is inserted, is high in height, so that the first dust collection part 510 can be easily inserted into the dust collection part accommodating space 360a.
The second cover portion 5162 can be connected to both left and right sides of the first cover portion 5161. The second cover portion 5162 can be formed in a form that extends horizontally from the lower side of the first cover portion 5161. That is, the upper surface of the first cover portion 5161 and the upper surface of the second cover portion 5162 can form a step so that the upper surface of the first cover portion 5161 is at a higher position.
In a state where the first dust collection part (510) is inserted into the chamber body 361, the side surface of the first cover portion 5161 is arranged to face the side surface of the rail body 3631. More specifically, the left and right sides of the first cover portion 5161 are arranged to face the side surface of the left and right rail bodies 3631. From another perspective, the first cover portion 5161 is arranged between the left and right rail bodies 3631. (See FIG. 29)
In a state where the first dust collection part 510 is inserted into the chamber body 361, the upper surface of the second cover portion 5162 is arranged to face the lower surface of the rail body 3631.
A transparent panel 5161b may be arranged on the upper surface of the first cover portion 5161.
The transparent panel 5161b is arranged at a position corresponding to the position where the sterilization module 450 is arranged when the first dust collection part 510 is inserted into the chamber body 361. That is, when the first dust collection part 510 is inserted into the chamber body 361, the sterilization module 450 and the transparent panel 5161b are arranged to face each other.
The transparent panel 5161b is made of a material that allows the sterilizing light emitted from the sterilization module 450 to be transmitted toward the inside of the dust collection part body 511. For example, the transparent panel 5161b may be made of PMMA (Poly methyl methacrylate) material.
A dust inlet 5161a may be formed on the upper surface of the first cover part 5161 through which dust is introduced together with air from the first flow path 381. For example, the dust inlet 5161a may be circular. The first flow path 381 is connected to the upper side of the dust inlet 5161a. Accordingly, air sucked in by the suction force of the dust collecting motor 391 may be introduced into the dust collection body 511. The dust inlet 5161a may be arranged on the upper side of the first dust receiving space S1 described later.
Based on the state in which the first dust collection part 510 is inserted into the chamber body 361, the dust inlet 5161a and the air inlet 3611 of the chamber body 361 can be positioned to face each other.
At this time, since the dust inlet 5161a is formed on the upper surface of the first cover part 5161 having a rearward-downward slope, the cross-section of the dust inlet 5161a also has a rearward-downward slope. As explained above, the cross-section of the air inlet 3611 also has a rearward-downward slope. Since the air inlet 3611 and the dust inlet 5161a have slopes in the same direction, they can be sealed without being separated from each other.
An inlet cover 5163 that opens and closes a dust inlet 5161a can be combined on the inner upper surface of the first cover part 5161. The inlet cover 5163 is configured to close or open the dust inlet 5161a and is provided in a shape corresponding to the shape of the dust inlet 5161a and can be combined on 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, the inlet cover 5163 can be opened toward the internal space of the dust collection body 511 (specifically, the first dust receiving space S1).
The inlet cover 5163 can keep the dust inlet 5161a closed when the dust collection motor 391 is not driven, and can open the dust inlet 5161a when the dust collection motor 391 starts driving.
To this end, the inlet cover 5163 can be equipped with a means for applying a restoring force in the direction of closing the dust inlet 5161a. The restoring force applying means can be an elastic member such as a spring, for example.
Through this configuration, the inlet cover 5163 always keeps the dust inlet 5161a closed when no suction force is applied, and prevents any odor, contamination, bacteria, etc. that may occur inside the first dust collection part 510 from spreading to the first path 381.
A rib 5161c may be formed protrudingly on the outer surface of the first cover portion 5161.
Here, the outer surface may refer to a surface connecting the upper surface of the first cover portion 5161 and the upper surface of the second cover portion 5162.
The rib 5161c may be formed in the front of the outer surface of the first cover portion 5161. The rib may protrude in a direction parallel to the upper surface of the second cover portion 5162. The rib 5161c may be inserted into the sliding space of the rail unit 363 (specifically, the rail body 3631) as the first dust collection part 510 is inserted into the chamber body 361.
As the first dust collection part 510 is inserted into the chamber body 361, the rib 5161c can push the interference protrusion 3632 positioned at the first position to the second position. (See FIG. 19)
The first dust collection part 510 may further include a lower cover 517 provided to cover the open lower side of the first dust collection part body.
A dust collection part hinge 519 may be arranged on one corner of the lower cover 517. When the lower cover 517 rotates around the collecting unit hinge 519, the interior of the dust collection part body 511 may be opened. As a result, the user may remove the dust collected in the dust collection part body 511)by discharging it to the outside.
A handle 5111b may be arranged on the front (or front side) of the dust collection part body 511. The handle 5111b is configured to be held by a user so that the first dust collection part 510 can be pulled out of the chamber body 361. The user can easily pull the first dust collection part 510 out from the chamber body 361 by holding the handle 5111b and pulling the first dust collection part 510 forward.
A finger groove 5111a may be provided on the dust collection part body 511 so that the user can easily hold the handle 5111b. The finger groove 5111a is formed as a groove into which the user's finger can be inserted. The finger home 5111a is formed in a shape in which the dust collection part body 511 is recessed toward the internal space of the first dust collection part body 510.
Through this configuration, the handle 5111b is not excessively formed to protrude outside the dust collection part body 511. That is, through this configuration, it can contribute to miniaturization of the cleaner station 300.
The dust collection part inner wall 512 can be arranged inside the dust receiving space of the dust collection part body 511. The dust collection part inner wall 512 can divide the dust receiving space of the dust collection part body 511 into two separate spaces. The dust collection part inner wall 512 can be arranged in a direction perpendicular to the ground.
The dust collection part inner wall 512 can be provided with a mesh net 5121. For example, the mesh net 5121 can form a part of the dust collection part inner wall 512. That is, when air flows from one side of the separated dust collection space to the other side, it can pass through the mesh net 5121.
Meanwhile, the accommodating space inside the first dust collection part 510 is divided into a first dust accommodating space S1 and a second dust accommodating space S2 by the inner wall 512 of the dust collection part.
A compression rotation unit 515 may be arranged in the first dust accommodating space S1. A cyclone 513 may be arranged in the second dust accommodating space S2. Air sucked in from the outside through the first flow path 381 first flows into the first dust accommodating space S1 and then passes through the mesh net 5121 to flow into the second dust accommodating space S2
Through this, relatively large dust can be filtered out in the mesh net 5121. The filtered large dust is collected and stored in the lower part of the first dust accommodating space S1.
A plurality of cyclones 513 may be provided. For example, at least two or more cyclone bodies in a cone shape or a cylinder shape may be provided.
Referring to FIG. 25, each cyclone body includes an inlet body 5131 arranged so that air passing through the mesh net 5121 is introduced. Each cyclone body further includes an outlet body 5132 connected to the discharge path 518.
The discharge path 518 is a path connected to the dust collection motor 391 and, as described above, is a path that constitutes a part of the second path 382.
Air is sucked from the discharge body 5132 by the suction force applied to the discharge path 518, and a cyclone flow is generated in the inlet body 5131. By this cyclone flow, fine dust can be filtered from the air that has passed through the mesh net 5121.
The first dust collection part 510 may include a compression rotation unit 515.
The compression rotation unit 515 is a configuration provided to compress dust collected in the first dust collection part 510.
Referring to FIG. 24 and FIG. 26, the compression rotation unit 515 is arranged inside the dust accommodating space of the dust collection part body 511. More specifically, the compression rotation unit 515 is arranged inside the first dust accommodating space S1 of the dust collection part body 511.
The compression rotation unit 515 is arranged movably inside the dust collection body 511. The compression rotation unit 515 can move in a direction that compresses the dust collected inside the first dust accommodating space S1. In an embodiment of the present invention, the compression rotation unit 515 can be arranged rotatably in the first dust accommodating space S1
The compression rotation unit 515 can rotate around an axis arranged in the longitudinal direction inside the dust collection body 511 (or the first dust receiving space S1). More specifically, the compression rotation unit 515 can include a rotation shaft member 5151, a fixed plate 5152, and a rotating plate 5153.
The rotation shaft member 5151 can be arranged in the vertical direction inside the dust collection part body 511, i.e., in the first dust accommodating space S1. The rotation shaft member 5151 can be rotated by receiving power from the compression motor 3622 described above. The central axis of the rotation shaft member 5151 can form a coaxial axis with the central axis of the first dust accommodating space S1.
The lower part of the rotation shaft member 5151 can be connected to and supported by the bottom surface of the first dust accommodating space S1. The upper part of the rotation shaft member 5151 can be spaced apart from the dust inlet 5161a by a predetermined distance so as not to interfere with the opening of the inlet cover 5163. (See FIG. 30)
he fixed plate 5152 may be fixedly arranged on one side inside the first dust collection part 510. More specifically, the fixed plate 5152 may be arranged in the upper and lower direction in the first dust accommodating space S1 and may be fixedly connected to one side of the inner surface of the dust collection part body 511 forming the first dust accommodating space S1. The fixed plate 5152 may have a square flat plate shape. The fixed plate 5152 may be arranged on the opposite side to the mesh net 5121.
The fixed plate 5152 may completely or partially shield the first dust accommodating space S1 and compress dust that is pushed and moved by the rotation of the rotating plate 5153 together with the rotating plate 5153.
The rotating plate 5153 is connected to and arranged on the outer surface of the rotary shaft member 5151 and can rotate together with the rotary shaft member 5151. More specifically, the rotating plate 5153 is arranged between the inner surface of the dust collection part body 511 forming the first dust accommodating space S1 and the outer surface of the rotary shaft member 5151 and can rotate.
The shape of the rotating plate 5153 is basically a square flat plate, but can be modified to a shape that avoids interference with other components arranged in the first dust accommodating space S1. For example, a cut portion can be formed on the upper end of the rotating plate 5153 so as not to interfere with the rotation radius of the inlet cover 5163 when the inlet cover 5163 opens the dust inlet 5161a. (See FIG. 30)
The rotating plate 5153 can rotate in both the forward and reverse directions. Based on the state of looking at the first dust accommodating space S1 from above (i.e., looking down at the first dust collection part 510 from above), clockwise rotation can be defined as forward rotation, and counterclockwise rotation can be defined as reverse rotation.
When the rotating plate 5153 rotates forward, one side of the rotating plate 5153 and one side of the fixed plate 5152 meet to compress the dust. Similarly, when the rotating plate 5153 rotates in the reverse direction, the other side of the rotating plate 5153 and the other side of the fixed plate 5152 meet to compress the dust. In other words, some of the compressed dust exists near one side of the fixed plate and the rest exists near the other side of the fixed plate 5152.
The compression rotation unit 515 may further include a cleaning member 5154.
Referring to FIG. 24 and FIG. 26, the cleaning member 5154 is coupled to the end of the rotating plate 5153 on the opposite side where the rotary shaft member 5151 is arranged. That is, one end of the rotating plate 5153 is coupled to the rotary shaft member 5151 and the other end is coupled to the cleaning member 5154.
The cleaning member 5154 may be arranged to rotate together with the rotating plate 5153 while in contact with the mesh net 5121. More specifically, one edge of the cleaning member 5154 may be arranged to contact one surface of the mesh net 5121.
Through this, the cleaning member 5154 can rotate while scraping the mesh net 5121 when rotating together with the rotating plate 5153, and foreign substances stuck to the mesh net 5121 can be removed. The cleaning member 5154 can be, for example, a rubber scrubber.
Meanwhile, as described above, the first dust collection part 510 can include a transmission gear 514.
The transmission gear 514 can be coupled to the lower cover 517 of the first dust collection part 510. When the first dust collection part 510 is inserted into the dust collection part accommodating space 360a, the transmission gear 514 and the driving gear 3621 can be meshed with each other, and the rotational power of the compression motor 3622 can be transmitted to the compression rotation unit 515 through the driving gear 3621 and the transmission gear 514.
Referring to FIG. 24, FIG. 27 and FIG. 28, the transmission gear (514) and the drive gear 3621 are described in detail.
FIG. 27 is an enlarged view of the drive gear 3621 and the transmission gear 514, and FIG. 28 is a perspective view of the drive gear viewed from the bottom according to one embodiment.
The transmission gear 514 can be connected to the rotation shaft member 5151 of the compression rotation unit 515. A gear tooth 5142 that is engaged with the drive gear 3621 is arranged on the lower outer circumference of the transmission gear 514. A gear shaft 5141 that is coaxially connected to the rotation shaft member 5151 is arranged on the upper center of the transmission gear 514.
The gear shaft 5141 can be inserted into the receiving space of the dust collection part body 511 through the hole formed in the lower cover 517. The gear shaft 5141 can be configured to be inserted into the hollow formed in the rotation shaft member 5151. That is, the size of the outer circumferential diameter of the gear shaft 5141 can be formed smaller than the size of the outer circumferential diameter of the rotation shaft member 5151.
The gear shaft 5141 and the rotation shaft member 5151 can be formed with a mechanical structure that engages each other so that they can rotate at the same angular velocity. For example, the mechanical structure can be a protrusion and groove structure.
The drive gear 3621 can include a gear body 3621a, a shaft connecting portion 3621b, and gear teeth 3621c.
The gear body 3621a forms the outer appearance of the drive gear 3621. The gear teeth 5142 of the transmission gear 514 and the gear teeth 3621c that are engaged with each other are formed and arranged on the upper part of the gear body 3621a. A pattern 3621d in which protrusions and grooves alternate and are continuous may be formed on the lower periphery of the gear body 3621a.
The upper diameter of the gear body 3621a on which the gear teeth 3621c are arranged and the lower diameter of the gear body 3621a on which the pattern 3621d is formed may have different sizes.
A shaft connecting portion 3621b connected to the motor shaft of the compression motor 3622 is formed at the center of the gear body 3621a. The shaft connecting portion 3621b can be formed and arranged in a cylindrical shape inside the gear body 3621a. The shaft connecting portion 3621b can have a hole formed in a shape corresponding to the motor shaft so that the motor shaft can be inserted.
Accordingly, when the compression motor 3622 rotates, the drive gear 3621 rotates together.
A plurality of ribs 3621e can be radially arranged on the outer surface of the shaft connecting portion 3621b so as to support the shape of the shaft connecting portion 3621b.
The pattern 3621d formed on the drive gear 3621 may be formed so that the widths of adjacent protrusions and grooves are different from each other. The protrusions and grooves formed on the pattern 3621d may be defined as phases that are distinguished according to the size of the formed width.
At this time, the order in which the phases of the pattern 3621d are arranged may be formed so that they are different from each other with respect 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.
The pattern 3621d may be composed of four phases as a set. 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, the protrusions and grooves may be formed alternately.
Here, the widths of the first to fourth phases can be formed to be all different, and each phase can be distinguished through the size of the width. For example, in the embodiment illustrated in FIG. 28, a protrusion having a width of pt_d1 (mm) can be defined as the first phase, a groove having a width of pt_d2 (mm) can be defined as the second phase, a protrusion having a width of pt_d3 (mm) can be defined as the third phase, and a groove having a width of pt_d4 (mm) can be defined as the fourth phase.
The arrangement order of each phase can be repeated in the order of 1-2-3-4 when looking at the gear body 3621a of the drive gear 3621 while moving in the first rotation direction rd1. Accordingly, when looking at the gear body 3621a of the drive gear 3621 while moving in the second rotation direction rd2 opposite to the first rotation direction rd1, each phase is repeated in the order of 4-3-2-1.
In this way, through the arrangement of the directional pattern 3621d formed on the drive gear 3621, the controller 700 described later can detect whether the drive gear 3621 is currently rotating in the first rotation direction rd1 or the second rotation direction rd2.
FIG. 29 is a view showing a flow path of air related to dust collection while the first dust collection part is inserted in a chamber body according to one embodiment. FIG. 30 is a view showing the air flow path related to dust collection when the first dust collection part is inserted into the chamber body in one embodiment.
Air that is introduced into the first dust accommodating space S1 of the dust collection part body 511 through the first duct 381 is separated from large dust as it passes through the mesh net 5121, and the air from which the large dust is separated is introduced into the second dust accommodating space S2.
Thereafter, air introduced into the second dust accommodating space S2 is separated from even fine dust as it passes through the cyclone 513, and the air from which even the fine dust is separated is introduced into the discharge duct 518 provided in the dust collection part body 511.
Air that has exited the discharge path 518 flows through the prefilter module 470 to the dust collection motor 391.
Below, the detailed structure of the second dust collection part 520 is described.
FIG. 31 is a view of components related to a second dust collection part which are separated and developed according to one embodiment. FIG. 32 is a cross-sectional view of the second dust collection part viewed from the side.
Referring to FIG. 31 and FIG. 32, the second dust collection part 520 may include a dust bag 521, an outer plate 522, and an inner plate 523.
The dust bag 521 is configured to receive dust sucked from the cleaner 200 and store it inside.
The dust bag 521 may be provided so that the volume increases and dust is received inside when suction power is generated by the dust collection motor 391. To this end, the dust bag 521 may be made of a breathable material. More specifically, the dust bag 521 may be made of a material that allows air to pass through but does not allow foreign substances such as dust to pass through. For example, the dust bag 521 may be made of a non-woven material and may have a hexahedral shape when the volume increases.
A dust inlet 5212 is formed in the dust bag 521. The dust inlet 5212 is formed by penetrating the dust bag 521 on the upper side of the dust bag 521 and serves as a passage that guides air and dust flowing in from the air inlet 3611 of the chamber body 361 into 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 by penetrating the dust bag 521. The light transmitting hole 5211 may be formed at a position facing one side of a transparent panel 524 to be described later. That is, the light transmitting hole 5211 may be arranged in front of the dust inlet 5212. When the second dust collection part 520 is fully inserted into the dust collection part accommodating space 360a, the sterilization module 450 may be arranged above the light transmitting hole 5211. As a result, sterilizing light may be irradiated into the interior of the dust bag 521 through the transparent panel 524.
The outer plate 522 may be coupled to the upper exterior of the dust bag 521.
The outer plate 522 may include a plate body 5221 in the shape of a square plate.
Part of the left and right ends of the plate body 5221 may be inserted into the sliding space of the rail body 3631. From another perspective, the left and right ends of the plate body 5221 may be fitted into the rail body 3631, and one side of the plate body 5221 may be supported by the inner lower surface of the rail body 3631. Through this configuration, the plate body 5221 may be inserted into the rail body 3631 in a sliding manner.
The dust inlet 5222 is formed in the plate body 5221. The dust inlet 5222 serves as a passage that guides air and dust flowing in from the air inlet 3611 of the chamber body 361 to the inside of the dust bag 521.
The outer plate 522 may include a handle 5223.
The handle 5223 may be coupled to the front end of the plate body 5221. The handle 5223 may be formed integrally with the plate body 5221. The handle 5223 may be formed by being vertically connected from the plate body 5221.
The user may hold the handle 5223 to push the outer plate 522 into the rail body 3631. The user can pull the handle 5223 to remove the outer plate 522 from the rail body 3631.
The outer plate 522 may include a connecting member 5224.
The connecting member 5224 may be arranged at the rear of the dust inlet 5222. The connecting member 5224 may be formed in a form that protrudes downward from the lower 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 plate 523 to be described later.
The outer plate 522 may include a supporting member 5225.
The supporting member 5225 may be arranged at the front of the outer plate 522. The supporting member 5225 may be formed in a form that protrudes downward from the lower surface of the outer plate 522 by a predetermined length.
The support member 5225 is formed on the left and right sides of the outer plate 522 in the form of a rib, and the lower end thereof can contact the lower inner surface of the rail body 3631 based on the state in which the outer plate 522 is inserted into the rail body 3631.
The second dust collection part (520) is lifted forward by the support member 5225 as it is inserted into the dust collection part accommodating space 360a. That is, when the second dust collection part 520 is completely inserted into the dust collection part accommodating space 360a, the second dust collection part 520 is tilted to have a rearward-downward slope. (See FIG. 34)
Through this configuration, the outer plate 522 can be supported in a state in which it is raised toward the air inlet 3611 of the chamber body 361.
As described above, in the embodiment of the present invention, the open cross-section of the air inlet 3611 has a backward-downward slope. At this time, the second dust collection part 520 is also inserted into the rail unit 363 in a tilted state so as to have a backward-downward slope, so that the air inlet 3611 and the dust inlet 5222 have the same slope, so that they can be sealed without being separated from each other.
The outer plate 522 may include a light transmitting hole 5226.
The light transmitting hole 5226 may be formed by penetrating the plate body 5221. The light transmitting hole 5226 may be formed at a position facing one side of the transparent panel 524 described below. That is, the light transmitting hole 5226 may be arranged in front of the dust inlet 5222.
When the second dust collection part 520 is fully inserted into the dust collection part accommodating space 360a, the sterilization module 450 can be placed above the light transmitting hole 5226. As a result, the sterilizing light can be irradiated into the interior of the dust bag 521 through the transmitting panel 524.
The inner plate 523 can be combined with the upper interior of the dust bag 521.
The inner plate 523 can include a plate body 5231 in the shape of a square flat plate.
The dust inlet 5232 is formed in the plate body 5231. The dust inlet 5232 serves as a passage that guides air and dust flowing in from the air inlet 3611 of the chamber body 361 to the interior of the dust bag 521.
The inner plate 523 may include a lateral wall 5233.
The lateral wall 5233 is configured to limit and guide the flow direction of air introduced into the interior of the dust bag 521. The lateral wall 5233 may be arranged adjacent to the dust inlet 5232. The lateral wall 5233 may be formed to protrude downward from the inner surface of the plate body 5231. That is, the lateral wall 5233 may be arranged to extend toward the inner space of the dust bag 521.
The lateral wall 5233 may be arranged symmetrically on the left and right sides of the dust inlet 5232. Therefore, the lateral wall 5233 may block air introduced into the dust inlet 5232 from flowing to the left or right.
Meanwhile, when the inlet cover 525 described later is open, the rearward flow of air can also be blocked.
As a result, 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 irradiated forward of the dust inlet 5232.
The inner plate 523 can include a connecting member insertion groove 5234.
The connecting member insertion groove 5234 may be arranged at the rear of the dust inlet 5232. The connecting member insertion groove 5234 may be formed in a form in which the plate body 5231 penetrates. The connecting member 5224 of the outer plate 522 may be inserted into the connecting member insertion groove 5234.
The inner plate 523 may include an inlet pipe 5235.
The inlet pipe 5235 may be coupled to the lower surface of the plate body 5231. The inlet pipe 5235 may be arranged in a form surrounding the dust inlet 5232. The inlet pipe 5235 may be formed integrally with the plate body 5231. The open cross section of the inlet pipe 5235 may have a rearward-downward slope.
The lower end of the inlet pipe 5235 can be closed by the inlet cover 525 described later. As a result, the dust inlet 5232 can also be closed.
The inner plate 523 can include an inlet cover fixing member 5236.
The inlet cover fixing member 5236 can be arranged at the rear of the dust inlet 5232. The inlet cover fixing member 5236 can be coupled to the lower surface of the plate body 5231 in a form surrounding the connecting member insertion groove 5234. The inlet cover fixing member 5236 can be formed integrally with the plate body 5231.
The inlet cover insertion groove 5236a can be formed in the inlet cover fixing member 5236. At least a portion of the inflow cover 525 can be inserted and fixed into the inflow cover insertion groove 5236a. The inflow cover insertion groove 5236a has a rearward downward slope and can extend in the left-right direction. Accordingly, the inflow cover 525 can be inserted from the front upper side to the rear downward side.
The transparent panel 524 may be combined with the inner plate 523.
The transparent panel 524 is arranged at a position corresponding to the position where the sterilization module 450 is arranged when the second dust collection part 520 is inserted into the chamber body 361. That is, when the second dust collection part 520 is inserted into the chamber body 361, the sterilization module 450 and the transparent panel 524 are arranged to face each other.
The transparent panel 524 is made of a material that allows the sterilizing light emitted from the sterilization module 450 to be transmitted toward the inside of the dust collection part body 511. For example, the transparent panel 524 may be made of PMMA (Poly methyl methacrylate) material.
The inlet cover 525 that opens and closes the dust inlet 5232 can be coupled to the inner side of the inner plate 523. The inlet cover 525 can be placed at the end of the inlet pipe 5235.
The inlet cover 525 can be made of an elastic material. For example, the inlet cover 525 can be made of a rubber material.
The inlet cover 525 can open one side of the inlet pipe 5235 by 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 can be inserted and coupled into the inlet cover insertion groove 5236a.
The inlet cover insertion groove 5236a has a large backward-downward slope, while the open cross-section of the inlet pipe 5235 has a smaller backward-downward slope. Therefore, when the inlet cover 525 is inserted into the inlet cover insertion groove 5236a, its shape is transformed into a shape that is bent at one point.
At this time, the inlet cover 525 is applied with a restoring force toward the direction in which it is about to unfold again based on the bent point.
Through this configuration, the inlet cover 525 can be closely attached to the inlet pipe 5235 while the inlet cover 525 is inserted into the inlet cover insertion groove 5236a. In other words, the inlet cover 525 does not sag due to its own weight when the dust collection motor 391 is not driven.
The inlet cover 525 keeps the dust inlet 5232 closed when the dust collection motor 391 is not driven, and can open the dust inlet 5232 when the dust collection motor 391 starts to drive.
When the dust collection motor 391 is operated, the inlet cover 525 is deformed toward the inner space of the dust bag 521 to open the inlet pipe 5235, and when the dust collection motor 391 is stopped, it is restored by elasticity to close the inlet pipe 5235.
Therefore, when the second dust collection part 520 is separated from the cleaner station, there is an effect of preventing dust from flying outside, flies escaping, or bad smells from spreading.
In addition, since the inlet pipe 5235 is closed when the dust collecting motor 391 is not running even when the second dust collection part 520 is connected to the cleaner station, there is an effect of preventing dust or odor from flowing back through the first flow path 381.
FIG. 33 is a perspective view showing the state where the second dust collection part is inserted in the chamber body according to one embodiment. FIG. 34 is a view showing a flow path of air related to dust collection in the state where the second dust collection part 520 is inserted in the chamber body 361.
When an airflow is formed by the suction power of the dust collection motor 391, the air containing foreign substances flowing from inside the dust bin 220 of the cleaner 200 moves to the dust bag 521 through the first flow path 381, and leaves only the foreign substances in the dust bag 521 and exits the dust bag 521.
At this time, the dust flowing in through the first flow path 381 is blocked from flowing in the left and right directions by the lateral wall 5233 and from flowing in the rear direction by the inlet cover 525, so that it flows forward and downward toward the sterilizing light irradiated by the sterilization module 450 as shown in the arrow direction of FIG. 34.
In addition, the air that has exited the dust bag 521 flows to the dust collection motor 391 through the pre-filter module 470.
Meanwhile, when the dust collection motor 391 is driven and an air flow is formed in the second dust collection part 520, the gear passage hole 3613a is exposed without blockage, so suction force is also applied to the gear passage hole 3613a. (see the direction of the dotted arrow in FIG. 33)
In this way, if suction force is directly applied to the compression motor 3622 through the gear passage hole 3613a, a failure of the compression motor 3622 may be induced.
FIG. 35 is an enlarged cross-sectional view showing a sealing member configured to seal a gear passage hole according to one embodiment.
In an embodiment according to the present invention, the compression drive unit 362 may further include a sealing member 3623 arranged between the drive gear 3621 and the chamber body 361.
The sealing member 3623 may be arranged along the outer circumference of the gear body 3621a of the drive gear 3621. The sealing member 3623 may be arranged between the outer surface of the gear body 3621a of the drive gear 3621 and the lower outer surface of the chamber body 361.
In this way, the sealing member 3623 may seal between the gear passage hole 3613a and the compression motor 3622 to block the air flow between the compression motor 3622 and the dust collection part accommodating space 360a.
The sealing member 3623 may include a first sealing portion that contacts the chamber body 361 and a second sealing portion that contacts the gear body 3621a. The first sealing portion and the second sealing portion may be configured to be connected to each other at one end and spaced apart at the other end.
Through this configuration, as suction force is applied by the dust collection motor 391, the other end of the first sealing portion and the other end of the second sealing portion are compressed in a direction in which they come closer to each other. Therefore, the sealing force is further strengthened by driving the dust collection motor 391, and suction force is prevented from being directly applied to the compression motor 3622.
FIG. 36 is a block view of a cleaner station according to one embodiment.
Referring to FIG. 36, the cleaner station 300 may further include a controller 700 that controls each component of the cleaner station 300. The controller 700 may be mounted on a printed circuit board.
The controller 700 may include all types of devices capable of processing data, such as a processor. Here, the term 'processor' may refer to a data processing device built into hardware, for example, having a physically structured circuit to perform a function expressed by a code or command included in a program. As an example of a data processing device built into hardware, a microprocessor, a central processing unit (CPU), a processor core, a multiprocessor, an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA), and the like may be included, but the scope of the present invention is not limited thereto.
When the mounting sensor 325 detects the mounting of the cleaner 200, the mounting sensor 325 can transmit a signal that the cleaner 200 is mounted to the mounting part 320 to the controller 700. At this time, the controller 700 can receive the signal of the mounting sensor 325 and determine that the cleaner 200 is mounted to the mounting part 320.
In addition, when power is supplied to the battery 240 of the cleaner 200 from the charging terminal 328, the controller 700 can determine that the cleaner 200 is mounted to the mounting part 320.
When the controller 700 determines that the cleaner 200 is coupled to the mounting part 320, it controls the fixing unit motor 780 to rotate in the forward direction, thereby fixing the cleaner 200 to the mounting part 320.
The cleaner station 300 may further include a fixing detection unit 770 that transmits a signal to the controller 700 that the cleaner 200 is fixed to the mounting part 320 when the fixing member 331 or the fixing unit link 335 moves to a predetermined fixed point.
The controller 700 may determine that the cleaner 200 is fixed to the mounting part 320 by receiving a signal from the fixing detection unit 770 that the cleaner 200 is fixed. The controller 700 can control the fixing unit motor 780 to stop operating when it is determined that the cleaner 200 is fixed.
Meanwhile, when the emptying of the dust bin 220 is completed, the controller 700 can control the fixing unit motor 780 to rotate in the reverse direction to release the fixation of the cleaner 200 and the mounting part 320.
The controller 700 can control the door motor 342 to rotate in the forward direction to open the door 341 of the cleaner station 300.
The cleaner station 300 can further include a door open/close detection part 760 that transmits a signal to the controller 700 that the door 341 is opened when the door 341 or the door arm 343 reaches a predetermined opening position.
The controller 700 can receive a signal from the door open/close detection part 760 and determine that the door 341 is open. If the controller 700 determines that the door 341 is open, the controller 700 can control the door motor 342 to stop driving.
Meanwhile, when the emptying of the dust bin 220 is completed, the controller 700 can control the door motor 342 to rotate in the reverse direction to close the door 341.
The controller 700 can open the discharge cover 222 of the cleaner 200 by controlling the drive of the cover opening motor 352.
The cleaner station 300 can further include a cover opening detection part 720 that transmits a signal to the controller 700 that the discharge cover 222 is opened when the push protrusion 351 reaches a predetermined opening position.
The controller 700 can determine that the discharge cover 222 is open by receiving a signal from the cover opening detection part 720. If the controller 700 determines that the discharge cover 222 is open, the controller 700 can control the operation of the cover opening motor 352 to stop.
The controller 700 can control the sterilization module 450. For example, the controller 700 can turn on the light source of the sterilization module 450 after dust is captured in the dust collection part 500 or at a predetermined time interval to sterilize viruses or microorganisms existing inside the dust collection part 500.
The controller 700 can control the operation of the dust collection motor 391. The controller 700 can control the dust collection motor 391 to operate for a predetermined period of time so that dust inside the dust bin 220 is sucked into the dust collection part 500.
The controller 700 can control the compression motor 3622. The controller 700 can control the compression motor 3622 to operate a predetermined number of times and/or a predetermined time to compress the dust collected inside the dust collection part 500 (specifically, the first dust collection part 510.
The controller 700 can control the compression motor 3622 to operate when it determines that the cleaner 200 is mounted to the mounting part 320. The controller 700 can control the compression motor 3622 to operate after the dust collection is completed and the operation of the dust collection motor 391 is stopped.
The controller 700 can control the display 730. The controller 700 can display various information related to the operation of the cleaner station 300 on the display 730.
For example, the information can include the progress of emptying the dust bin 220 of the cleaner 200, the charging level of the cleaner 200, guidance on the currently operating configuration, the degree of dust compression, etc.
The controller 700 may display a notification on the display 730 in multiple preset stages according to the amount of dust collected in the dust collection part 500. For example, the controller 700 may display a notification on the dust compression status in multiple stages on the display 730 according to the amount of dust collected.
In addition, the controller 700 may display the inability to drive the dust collection motor 391 on the display 730)to alert the user to remove the dust collected in the dust collection part 500 at an appropriate time.
The cleaner station 300 may further include a memory 740. The memory 740 may store an application program for driving the cleaner station 300 and various related data.
Preset values related to the operation of the cleaner station 300 described in this specification may be stored in the memory 740.
The memory 740 may include a magnetic storage media or a flash storage media, but the scope of the present invention is not limited thereto. The memory 740 may include a built-in memory and/or an external memory, and may include a volatile memory such as a DRAM, an SRAM, or an SDRAM, a nonvolatile memory such as an OTPROM (one time programmable ROM), a PROM, an EPROM, an EEPROM, a mask ROM, a flash ROM, a NAND flash memory, or a NOR flash memory, a flash drive such as an SSD, a CF (compact flash) card, an SD card, a Micro-SD card, a Mini-SD card, an Xd card, or a memory stick, or a storage device such as an HDD.
The memory 740 may be included in the controller 700 or may be provided as a separate configuration.
The cleaner station 300 may further include an input part 750. The input part 750 generates key input data that a user inputs to control the operation of the cleaner station 300. To this end, the input part 750 may be composed of a key pad, a dome switch, a touch pad (static/electrostatic), etc. In particular, when the touch pad forms a mutual layer structure with the display 730, it may be called a touch screen.
The input part 750 and/or the display 730 may be arranged on the upper surface 313 of the housing 310.
Meanwhile, the cleaner station 300 can distinguish the type of the dust collection part 500 coupled to the chamber part 360 based on the operation form of the compression drive unit 362.
The controller 700 can control the compression drive unit 362. More specifically, the controller 700 can control the rotation drive of the compression motor 3622.
The controller 700 can rotate the compression motor 3622 to distinguish the type of the dust collection part 500.
A method for distinguishing or determining the type of the dust collection part 500 will be specifically described as follows.
The controller 700 can drive compression motor 3622 when the dust bin 220 of the cleaner 200 is coupled to the housing 310. That is, when the dust bin 220 is coupled to the housing 310, the compression motor 3622 can be automatically driven.
In another embodiment, the controller 700 can drive the compression motor 3622 when the user presses the operation button of the cleaner station 300. That is, when the dust bin 220 is coupled to the housing 310, the compression motor 3622 can be manually driven. At this time, the operation button can be placed on the display 730.
In another embodiment, the controller 700 can drive the compression motor 3622 when the dust collection part 500 is coupled to the chamber part 360. In this embodiment, unlike the previously described embodiment, the compression motor 3622 can be driven regardless of whether the dust bin 220 is coupled to the housing 310.
The driving of the compression motor 3622 performed to determine the type of the dust collection part 500 must be performed before the driving of the dust collection motor 391 that collects dust. At this time, the driving of the compression motor 3622 is necessarily performed regardless of the type of the dust collection part 500 coupled to the chamber part 360. That is, whether the first dust collection part 510 is coupled to the chamber body 361 or the second dust collection part 520 is coupled, the controller 700 drives the compression motor 3622.
The controller 700 can drive the compression drive unit 362 for a predetermined first time t1.
The controller 700 can determine the type of the dust collection part 500 currently coupled to the chamber part 360 through whether the rotation direction of the compression drive unit 362 is changed within the first time t1.
At this time, the first time t1 can be set to a value greater than the time required for the rotating plate 5153 mechanically coupled to the compression drive unit 362 to rotate 360 degrees inside the first dust collection part 510.
When the first dust collection part 510 is inserted into the chamber body 361, the rotation direction of the compression drive unit 362 must be changed within the first time (t1).
The state in which the first dust collection part 510 is inserted into the chamber body 361 means that the drive gear 3621 coupled with the compression motor 3622 is gearconnected to the transmission gear 514 of the first dust collection part 510.
When the compression motor 3622 rotates, the rotational power transmitted through the drive gear 3621 and the transmission gear 514 rotates the rotating plate 5153. The rotating plate 5153 cannot rotate more than 360 degrees in one direction because it is blocked by the fixed plate 5152 when rotating in only one direction or by dust accumulated inside the first dust collection part 510.
That is, before the 360-degree rotation of the rotating plate 5153 is completed, the compression drive unit 362 must change the rotation direction to the opposite direction.
The controller 700 can detect the rotation direction change of the compression drive unit 362 that is completed within the first time t1 to determine that the first dust collection part 510 is coupled to the chamber part 360.
Meanwhile, the first time (t1) does not necessarily have to be the time required for the rotating plate 5153 to rotate 360 degrees. The first time (t1) may be set to another appropriate value calculated by considering the initial position and rotation speed of the rotating plate 5153, the position of the fixed plate 5152, etc.
Meanwhile, the drive gear 3621 and the compression motor 3622 constituting the compression drive unit 362 are connected in the longitudinal direction and rotate in the same direction, so the rotation direction of the compression drive unit 362 in this specification is used with the same meaning as the rotation direction of the drive gear 3621 or the rotation direction of the compression motor 3622.
The detection of the change in the rotation direction of the compression drive unit 362 can be performed by detecting the arrangement order of the patterns 3621d formed on the drive gear 3621. For this purpose, the compression drive unit 362 may further be provided with a compression state detection unit 790 arranged adjacent to the drive gear 3621. The compression state detection unit 790 may be a photo interrupter.
The compression state detection unit 790 can detect a change in the pattern 3621d of the driving gear 3621 and generate an on/off signal. The on signal corresponds to a high signal, and the off signal corresponds to a low signal.
The controller 700 can receive the signal transmitted by the compression state detection unit 790 and determine the phase of the pattern 3621d of the current drive gear 3621.
If the phase of the pattern 3621d detected by the compression state detection unit 790 has the arrangement order of 1-2-3-4, the compression drive unit 362is rotating in the first direction. If the phase of the pattern 3621d detected by the photo interrupter has the arrangement order of 4-3-2-1, the compression drive unit 362 is rotating in the second direction. (See FIG. 28)
The compression drive unit 362 can be stopped when the first time (t1) has elapsed from the start of rotation.
On the other hand, in the case where the second dust collection part 520 is inserted into the chamber body 361, the rotation direction of the compression drive unit 362 is not changed within the first time (t1). This is because the second dust collection part 520 is of a dust bag type and therefore there is no member that can be connected to the drive gear 3621. (See FIG. 33)
That is, the compression drive unit 362 continues to rotate in one direction for the first time (t1). Through this, the controller 700 can determine that the second dust collection part 520 is coupled to the chamber part 360.
The compression drive unit 362 can be stopped when the first time (t1) has elapsed from the start of rotation.
Hereinafter, the operation of the cleaner station 300 after determining the type of the dust collection part 500 will be described.
In the embodiment of the present invention, the cleaner station 300 can be operated differently depending on the type of the dust collection part 500 coupled to the chamber part 360.
The operation of the cleaner station 300 when the first dust collection part 510 is coupled to the chamber part 360 will be examined as follows.
When the dust bin 220 is coupled to the housing 310 of the cleaner station 300, the fixing unit 330 can fix and seal the dust bin 220. The cover opening unit 350 can open the discharge cover 215 of the dust bin 220. The door unit 340 can open the door 341 of the cleaner station 300.
When the inside of the dust bin 220 and the inside of the flow path 380 are connected, the dust collection motor 391 is driven so that dust inside the dust bin 220 can be introduced into the inside of the first dust collection part 510 through the flow path 380. In other words, dust existing inside the dust bin 220 can be removed.
When the dust collection motor 391 is driven for a certain period of time and then stopped, a process of compressing dust collected in the first dust collection part 510 can be performed. This process is performed only when the dust collection part 500 is a 'bin' type first dust collection part 510.
More specifically, the compression motor 3622 may be driven to rotate, and the rotational power may be transmitted to the rotating plate 5153 through the drive gear 3621 and the transmission gear 514. The rotating plate 5153 may rotate to approach the fixed plate 5152 fixedly arranged on one side of the first dust collection part 510 and pressurize and compress the dust collected between the fixed plate 5152.
After the operation of the compression drive unit 362 is stopped and the dust compression is finished, the door unit 340 may close the door 341 of the cleaner station 300. At this time, the door unit 340 may perform an operation of pushing the discharge cover 215 of the dust bin 220 while closing the door 341, and through this, the dust bin 220 and the discharge cover 215 may be re-coupled. The fixing unit 330 that was fixing and sealing the dust bin 220 can be driven to release the fixing state.
Next, the operation of the cleaner station 300 when the second dust collection part 520 is combined with the chamber part 360 is examined as follows.
When the dust bin 220 is combined with the housing 310 of the cleaner station 300, the fixing unit 330 can fix and seal the dust bin 220. The cover opening unit 350 can open the discharge cover 215 of the dust bin 220. The door unit 340 can open the door 341 of the cleaner station 300.
When the inside of the dust bin 220 and the inside of the flow path 380 are connected, the dust collection motor 391 is driven so that dust inside the dust bin 220 can be introduced into the inside of the second dust collection part 520 through the flow path 380. That is, the dust existing inside the dust bin 220 can be removed.
Since the second dust collection part 520 is a dust bag type, when the second dust collection pat 520 is coupled to the chamber part 360, the compression drive unit 362 is not driven after the dust collection motor 391 is driven.
That is, when the second dust collection part 520 is coupled to the chamber part 360, after the dust collection motor 391 stops driving, the door unit 340 can immediately close the door 341 of the cleaner station 300 without driving the compression drive unit 362. At this time, the door unit 340 can push the discharge cover 215 of the dust bin 220 while closing the door 341, and through this, the dust bin 220 and the discharge cover 215 can be re-coupled. The fixing unit 330 that was fixing and sealing the dust bin 220 can be driven to release the fixed state.
In this way, the embodiment of the present invention can distinguish the collecting unit currently connected to the cleaner station, so that the cleaner station can be driven efficiently according to the shape of the collecting unit.
In addition, the collecting section can be distinguished by utilizing the compression drive section equipped for dust compression without having an additional sensor.
Although the present invention has been described with reference to the exemplified drawings, it is to be understood that the present invention is not limited to the embodiments and drawings disclosed in this specification, and those skilled in the art will appreciate that various modifications are possible without departing from the scope and spirit of the present invention. Further, although the operating effects according to the configuration of the present invention are not explicitly described while describing an embodiment of the present invention, it should be appreciated that predictable effects are also to be recognized by the configuration.
