Description

CLEANER STATION

The present invention relates to a vacuum cleaner station that sucks and captures dust from a vacuum cleaner using a dust bag made of an impermeable material.

In general, a vacuum cleaner is an electrical appliance that sucks up small pieces of trash or dust by sucking in air and filling the dust bin inside the product. It is commonly called a vacuum cleaner.

These cleaners can be divided into manual cleaners that perform cleaning while the user moves the cleaner, and automatic cleaners that perform cleaning while driving on their own. Manual cleaners can be divided into canister-type cleaners, upright cleaners, handheld cleaners, and stick-type cleaners, depending on the type of cleaner.

In the past, canister-type vacuum cleaners were widely used for home vacuum cleaners, but recently, handheld vacuum cleaners and stick vacuum cleaners that provide the dust bin and vacuum cleaner body as one unit, which improves convenience, have been widely used.

The canister-type vacuum cleaner has a main body and suction inlet connected by a rubber hose or pipe, and in some cases, a brush can be attached to the suction inlet for use.

Handheld vacuum cleaners are designed to maximize portability, and are light in weight but short in length, so the cleaning area may be limited when sitting down. Therefore, they are used to clean small areas such as desks, sofas, or inside cars.

Stick vacuums can be used standing up, so you can clean without bending down. Therefore, they are advantageous for cleaning while moving around a wide area. While a handheld vacuum cleaner cleans narrow spaces, a stick vacuum cleaner can clean a wider space and can clean high places that are out of reach. Recently, stick vacuum cleaners are provided in a modular type, so you can actively change the vacuum cleaner type for various purposes.

In addition, robot vacuum cleaners that clean on their own without user intervention are being used recently. Robot vacuum cleaners automatically clean the area they want to clean by moving around the area on their own and sucking up foreign substances such as dust from the floor.

However, conventional handheld vacuum cleaners, stick vacuum cleaners, and robot vacuum cleaners have small dustbins that store collected dust, which is inconvenient for users to have to empty the dustbins every time.

Additionally, there was a problem that when the dustbin was emptied, dust would fly around, which could have a harmful effect on the user's health.

Additionally, there was a problem that the suction power of the vacuum cleaner was reduced if the remaining dust in the dustbin was not removed.

Additionally, there was a problem of bad odor caused by residue if the remaining dust in the dustbin was not removed.

As the first prior art document, Korean Patent Publication No. 2161708 discloses a station including a dust bag.

The above first prior art document includes a station to which a dust bin of a vacuum cleaner is coupled, and a dust bag is arranged in the station. At this time, the dust bag is coupled to the inside of the housing of the vacuum cleaner along a sliding groove, and the outer surface of the dust bag is composed of a material that allows air to pass through and be filtered.

However, in the case of such permeable or semi-permeable dust bags, there is a problem that dust inside the dust bag can leak out of the dust bag, and bad odors can also leak out of the dust bag.

As a second prior art document, Korean Patent Publication No. 2021-0128783 discloses a station including a dust bag made of vinyl material.

The above second prior art patent document discloses a docking station to which a dust bin of a vacuum cleaner is connected, and a dust storage unit is arranged in the docking station. At this time, the dust storage unit includes a roll vinyl, and the roll vinyl is spread downward by the load of dust falling from the dust bin of the vacuum cleaner.

As in the second prior art patent document, if the dust bag inside the station is made of vinyl material, it has the effect of preventing the problems of dust leaking out or the generation of bad odors.

However, there is a problem that the roll vinyl is difficult to expand to an appropriate volume with only the load of dust sucked into the dust bin of the vacuum cleaner. If the volume of the roll vinyl is not expanded appropriately, the dust that should be captured in the vinyl may flow back out of the station, which may reduce the dust collection efficiency, so the user has to manually expand the roll vinyl, which is inconvenient.

Korean Patent Publication No. 2161708 Korean Patent Publication No. 2021-0128783

The present invention has been made to solve the above-mentioned problems, and the purpose of the present invention is to prevent dust or odor from leaking out of a dust bag.

Another object of the present invention is to automatically inflate the dust bag when dust is collected.

Another object of the present invention is to prevent the phenomenon of the dust bag flowing backwards in the wrong direction as the force for expanding the dust bag weakens.

In order to achieve the above-described object, according to one embodiment of the present invention, a cleaner station may include: a housing coupled to a dust bin of a cleaner; a dust collecting motor accommodated inside the housing and generating a suction force for sucking dust inside the dust bin; a dust separation unit accommodated inside the housing, arranged above the dust collecting motor, and separating dust in the air sucked by the dust collecting motor; a flow path unit including a first flow path connecting the dust bin and the dust separation unit and a second flow path guiding air passing through the dust separation unit to the dust collecting motor; a bag support unit arranged below the dust separation unit and providing a bag receiving space to accommodate a dust bag storing dust separated by the dust separation unit; and a partition unit arranged inside the bag support unit and dividing the bag receiving space into a first space and a second space.

In a cleaner station according to one embodiment of the present invention, the bag support may include a support body forming an outer appearance of the bag receiving space; and an air hole formed in the support body to connect the second flow path and the bag receiving space.

In a cleaning station according to one embodiment of the present invention, the compartment may include an air hole formed to connect the second space and the first space.

In a cleaner station according to one embodiment of the present invention, at least a portion of the suction air sucked by the dust collecting motor can flow through the second path, the second space, and a bypass suction path connected to the dust collecting motor.

In a cleaner station according to one embodiment of the present invention, at least a portion of the suction air sucked by the dust collecting motor can flow through the second passage, the second space, the first space, and a bypass suction path connected to the dust collecting motor.

In a cleaner station according to one embodiment of the present invention, the dust bag may be formed of an impermeable material.

In a cleaner station according to one embodiment of the present invention, the dust bag can be expanded by negative pressure formed in the bag receiving space when the dust collection motor is driven.

In a cleaner station according to one embodiment of the present invention, the partition can support the outer shape of the inflated dust bag from the other side so as not to obstruct the air flow of the second space disposed on one side.

A cleaning station according to one embodiment of the present invention may further include a pre-filter that filters foreign substances from air passing through the dust separation unit.

According to one embodiment of the present invention, a cleaner station may form a main suction path through which suction air flows directly from the second path to the dust collecting motor when the dust collecting motor is driven.

According to one embodiment of the present invention, a cleaner station may have a first bypass suction path formed through which suction air flows to the dust collecting motor through the second passage, the second space, and the first space.

According to one embodiment of the present invention, a cleaner station may have a second bypass suction path formed through which suction air flows to the dust collecting motor through the second passage and the second space.

According to one embodiment of the present invention, a cleaner station is configured such that the air flow in the first bypass suction path is maintained or blocked depending on the degree of expansion of the dust bag, and the air flow in the second bypass suction path can be maintained at all times regardless of the degree of expansion of the dust bag.

The vacuum cleaner station according to the present invention is equipped with a dust bag made of an impermeable material, thereby preventing the problem of dust leakage or odor leakage, which are problems of dust bags made of semi-permeable or permeable materials.

In addition, in the cleaner station according to the present invention, when the dust collecting motor is driven, suction air flows through the first bypass suction path passing through the bag receiving space in which the dust bag is received, and negative pressure is applied to the bag receiving space, so that the dust bag is automatically inflated. Therefore, there is an advantage in that the user does not have to manually unfold the plastic.

In addition, in the cleaner station according to the present invention, even when the dust bag in the bag receiving space is fully expanded and the first bypass suction path is blocked, the negative pressure in the bag receiving space is maintained while the suction air flows through the second bypass suction path passing through a space separated from the bag receiving space. Accordingly, the force for expanding the dust bag is not weakened, and the phenomenon of the dust bag flowing backwards in the wrong direction is also prevented.

The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.

Referring to FIGS. 1 to 4, a cleaner system (3) according to one embodiment of the present invention may include a cleaner (200) and a cleaner station (300).

The cleaner system (3) may include a cleaner station (300). A cleaner (200) may be coupled to the cleaner station (300). A cleaner (200) may be coupled to a side of the cleaner station (300). The cleaner station (300) may remove dust from a dust bin (220) of the cleaner (200).

First, the structure of the vacuum cleaner (200) will be described with reference to FIGS. 1 to 3 as follows.

The vacuum cleaner (200) may mean a vacuum cleaner that is manually operated by a user. For example, the vacuum cleaner (200) may mean a handheld vacuum cleaner or a stick vacuum cleaner.

The cleaner (200) can be mounted on the cleaner station (300). The cleaner (200) can be supported by the cleaner station (300). The cleaner (200) can be coupled to the cleaner station (300).

Meanwhile, in one embodiment of the present invention, the direction of the vacuum cleaner (200) can be defined based on the time when the bottom surface (lower surface) of the dust bin (220) and the battery housing (230) are placed on the ground.

At this time, the front may refer to the direction in which the suction unit (212) is arranged based on the suction motor (214), and the rear may refer to the direction in which the handle (216) is arranged based on the suction motor (214). In addition, when looking at the suction unit (212) from the suction motor (214), the direction in which it is arranged on the right may be referred to as the right, and the direction in which it is arranged on the left may be referred to as the left. In addition, in one embodiment of the present invention, the upper and lower sides may be defined along the direction perpendicular to the ground when the bottom surface (lower surface) of the dust bin (220) and the battery housing (230) are placed on the ground.

The vacuum cleaner (200) may include a main body (210). The main body (210) may include a main body housing (211), a suction unit (212), a dust separation unit (213), a suction motor (214), an air discharge cover (215), a handle (216), and an operating unit (218).

The main body housing (211) can form the exterior of the cleaner (200). The main body housing (211) can provide a space that can accommodate a suction motor (214) and a filter (not shown) inside. The main body housing (211) can be configured in a shape similar to a cylinder.

The suction part (212) may protrude outwardly from the main body housing (211). For example, the suction part (212) may be formed in a cylindrical shape with an open interior. The suction part (212) may be combined with an extension pipe (250). The suction part (212) may provide a path (hereinafter, referred to as a 'suction path') through which air containing dust may flow.

The dust separation unit (213) can be communicated with the suction unit (212). The dust separation unit (213) can separate dust sucked into the inside through the suction unit (212). The space inside the dust separation unit (213) can be communicated with the space inside the dust bin (220).

For example, the dust separation unit (213) may be provided with at least one cyclone unit capable of separating dust by cyclone flow. In addition, the space inside the dust separation unit (213) may be connected to the suction path. Accordingly, the air and dust sucked through the suction unit (212) flow spirally along the inner surface of the dust separation unit (213). Accordingly, a cyclone flow may occur in the inner space of the dust separation unit (213).

The dust separation unit (213) is connected to the suction unit (212) and is configured to apply the principle of a dust collector that utilizes centrifugal force to separate dust sucked into the interior of the main body (210) through the suction unit (212).

The dust separation unit (213) may further include a secondary cyclone that separates dust again from the air discharged from the cyclone. At this time, the secondary cyclone may be positioned inside the cyclone so that the size of the dust separation unit is minimized. The secondary cyclone may include a plurality of cyclone bodies arranged in parallel. The air discharged from the cyclone may be divided and passed through the plurality of cyclone bodies.

At this time, the axis of the cyclone flow of the secondary cyclone may also be extended 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 main 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 main body housing (211). The air exhaust cover (215) may accommodate a filter for filtering air. For example, the air exhaust cover (215) may accommodate a HEPA filter.

An air discharge port for discharging air sucked in by the suction force of the suction motor (214) may be formed in the air discharge cover (215).

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 port.

The handle (216) can be gripped by the user. The handle (216) can be positioned at the rear of the suction motor (214). For example, the handle (216) can be formed in a shape similar to a cylinder. Alternatively, the handle (216) can be formed in a curved cylinder shape. The handle (216) can be positioned at a predetermined angle with respect to the main body housing (211), the suction motor (214), or the dust separation unit (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 (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 (axial direction) of the grip portion (216a) and formed to extend toward the dust bin (220).

The upper surface of the handle (216) may form a portion of the outer appearance of the upper surface of the cleaner (200). This may prevent one component of the cleaner (200) from contacting 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 main body housing (211) or the suction motor (214). At least a portion of the first extension portion (216b) may extend in a horizontal direction.

The second extension portion (216c) may extend from the breaker portion toward the dust bin (220). At least a portion of the second extension portion (216c) may extend in a horizontal direction.

The operating unit (218) may be placed on the handle (216). The operating unit (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 operating unit (218).

The vacuum cleaner (200) may include a dust bin (220). The dust bin (220) may be connected to a dust separation unit (213). The dust bin (220) may store dust separated from the dust separation unit (213).

The dustbin (220) may include a dustbin body (221), a discharge cover (222), a dustbin compression lever (223), and a compressor (not shown).

The dustbin body (221) can provide a space for storing dust separated from the dust separation unit (213). For example, the dustbin body (221) can be formed in a shape similar to a cylinder.

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

The dustbin (220) may include a discharge cover (222). The discharge cover (222) may be placed on the lower surface of the dustbin (220).

The discharge cover (222) may be provided to open and close one end of the longitudinal direction of the dustbin body (221). Specifically, the discharge cover (222) may selectively open and close the lower part of the dustbin (220) that opens downward.

The discharge cover (222) may include a cover body (222a) and a hinge part (222b). The cover body (222a) may be formed to block a portion of the lower surface of the dustbin body (221). The cover body (222a) may rotate downward based on the hinge part (222b). The hinge part (222b) may be arranged adjacent to the battery housing (230). A torsion spring (222d) may be provided in the hinge part (222b). Therefore, when the discharge cover (222) is separated from the dustbin body (221), the cover body (222a) may be supported in a state in which it is rotated by a predetermined angle or more about the hinge part (222b) as an axis in the dustbin body (221) by the elastic force of the torsion spring (222d).

The discharge cover (222) can be coupled with 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 blocked (sealed) by the discharge cover (222) and the lower extension (221a).

The dustbin (220) may include a dustbin compression lever (223) (see FIG. 2). The dustbin compression lever (223) may be arranged outside the dustbin (220) or the dust separation unit (211). The dustbin compression lever (223) may be arranged to move up and down outside the dustbin (220) or the dust separation unit (213). The dustbin compression lever (223) may be connected to a compressor (not shown). When the dustbin compression lever (223) moves downward due to an external force, the compressor (not shown) may also move downward. Through this, convenience for the user may be provided. The compressor (not shown) and the dustbin compression lever (223) may return to their original positions by an elastic member (not shown). Specifically, when an external force applied to the dustbin compression lever (223) is removed, the elastic member may move the dustbin compression lever (223) and the compressor (not shown) upward.

A compressor (not shown) may be placed inside the dustbin body (221). The compressor may move in the internal space of the dustbin body (221). Specifically, the compressor may move up and down inside the dustbin body (221). Through this, the compressor may compress dust inside the dustbin body (221) downward. In addition, when the discharge cover (222) is separated from the dustbin body (221) and the lower part of the dustbin (220) is opened, the compressor may move from the upper part to the lower part of the dustbin (220) to remove foreign substances such as residual dust inside the dustbin (220). Through this, the suction power of the vacuum cleaner may be improved by preventing residual dust from remaining inside the dustbin (220). In addition, by preventing residual dust from remaining inside the dustbin (220), an unpleasant odor caused by residual substances may be eliminated.

The vacuum cleaner (200) may include a battery housing (230). The battery housing (230) may accommodate a battery (240). The battery housing (230) may be positioned at the lower side of the handle (216). For example, the battery housing (230) may have a hexahedral shape with an open bottom. The rear side of the battery housing (230) may be connected to the handle (216).

The battery housing (230) may include a receiving portion that opens downward. The battery (240) may be removed through the receiving portion of the battery housing (220).

The vacuum cleaner (200) may include a battery (240).

For example, the battery (240) may be detachably coupled to the cleaner (200). The battery (240) may be detachably coupled to the battery housing (230). For example, the battery (240) may be inserted into the interior of the battery housing (230) from the lower portion of the battery housing (230). With this configuration, the portability of the cleaner (200) may be improved.

Alternatively, 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.

The battery (240) can supply power to the suction motor (214) of the vacuum cleaner (200). The battery (240) can be placed at the bottom of the handle (216). The battery (240) can be placed at the rear of the dust bin (220).

According to an embodiment, when the battery (240) is coupled to the battery housing (230), 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 vacuum cleaner (200) is placed on the floor, the battery (240) may be immediately 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) may 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 a main body (210). The extension pipe (250) may be communicated with a suction portion (214) of the main body (210). The extension pipe (250) may be formed in a long cylindrical shape.

The main body (210) can be connected to an extension pipe (250). The main body (210) can be connected to a cleaning module (260) through the extension pipe (250). The main body (210) can generate suction force through a suction motor (214) and provide suction force to the cleaning module (260) through the extension pipe (250). External dust can be introduced into the main body (210) through the cleaning module (260) and the extension pipe (250).

The cleaner (200) may include a cleaning module (260). The cleaning module (260) may be connected to an 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 main 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 unit (370) of the cleaner station (300). At the same time, dust in the dust bin (220) can be collected by the dust collection unit (370) of the cleaner station (300) by the suction force of the dust collection motor (391) arranged inside the cleaner station (300). Through this, dust in the dust bin of the cleaner can be removed without a separate operation by the user, thereby providing user convenience. In addition, the inconvenience of the user having to empty the dust bin every time can be eliminated. In addition, dust can be prevented from flying when the dust bin is emptied.

The cleaner (200) can be coupled to the side of the housing (310). Specifically, the main body (210) of the cleaner (200) can be mounted on the coupling part (320). More specifically, the dustbin (220) and the battery housing (230) of the cleaner (200) can be coupled to the coupling surface (321) of the coupling part (320). The outer surface of the dustbin main body (221) can be coupled to the dustbin guide surface (322). The suction part (212) can be coupled to the suction part guide surface (326) of the coupling part (320). With this configuration, the central axis of the dustbin (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.

Below, the configuration of a cleaning station (300) of one embodiment of the present invention is described.

Referring to FIG. 4, a cleaner (200) may be coupled to a cleaner station (300). Specifically, a main body of a cleaner (200) may be coupled to a side of the cleaner station (300). More specifically, a dust bin (220) of the cleaner (200) may be coupled to a side of the cleaner station (300), and may be coupled through one side where a discharge cover (222) is disposed. Accordingly, when the discharge cover (222) is opened, dust in the dust bin (220) may be captured and removed inside the cleaner station (300).

The cleaner station (300) may include a housing (310). The housing (310) may form an exterior of the cleaner station (300). Specifically, the housing (310) may be formed in a pillar shape including at least one outer wall surface. As an 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 a dust collection unit (370) and a 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 toward 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. With this configuration, the dust collecting motor (391) can be stably supported, and even when the vacuum cleaner (200) is combined, there is an advantage in that the overall weight can be balanced.

Meanwhile, according to an embodiment, the bottom surface (311) may further include a ground support member (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 member (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 floor surface (311). For example, the outer wall surface (312) may mean a surface vertically connected to the floor surface (311). In another embodiment, the outer wall surface (312) may be arranged to be inclined at a predetermined angle with respect to the floor 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 on which the cleaner (200) is exposed when the cleaner (200) is coupled to the cleaner station (300). Accordingly, the first outer wall surface (312a) may form the appearance of the front side of the cleaner station (300).

Meanwhile, in order to understand 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 coupled 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 coupled to the cleaner station (300), the direction in which the suction motor (214) of the cleaner (200) is positioned can be called the front. And the direction opposite to the direction in which the suction motor (214) is positioned in the cleaner station (300) can be called the rear.

And, based on the internal space of the housing (310), the surface facing the front can be called the rear side of the cleaner station (300). Accordingly, the rear side can mean the direction in which the second outer wall surface (312b) is formed.

And, when looking at the front based on the internal space of the housing (310), the left side may be called the left side, and the right side may be called the right side. Accordingly, the left side may mean the direction in which the third outer wall surface (312c) is formed, and the right side may mean the direction in which the fourth outer wall surface (312d) is formed.

The first outer wall surface (312a) may be formed in a flat shape, or may be formed in an entirely curved shape, or may be formed to include a curved surface in a portion.

A coupling part (320) may be arranged on the first outer wall surface (312a). With this configuration, the cleaner (200) may be coupled to the cleaner station (300) and supported by the cleaner station (300). The specific configuration of the coupling part (320) will be described later.

Meanwhile, it is also possible to add a structure for mounting various types of cleaning modules (260) used in a vacuum cleaner (200) to the first outer wall surface (312a).

In this embodiment, the second outer wall surface (312b) may be a surface facing the first outer wall surface (312a). That is, the second outer wall surface (312b) may be placed at the rear of the cleaner station (300). The second outer wall surface (312b) may form the exterior of the rear of the cleaner station (300).

In this embodiment, the third outer wall surface (312c) and the fourth outer wall surface (312d) may refer to surfaces connecting the first outer wall surface (312a) and the second outer wall surface (312b). At this time, the third outer wall surface (312c) may be arranged on the left side of the cleaner station (300), and the fourth outer wall surface (312d) may be arranged on the right side of the cleaner station (300). Alternatively, the third outer wall surface (312c) may be arranged on the right side of the cleaner station (300), and the fourth outer wall surface (312d) may be arranged on the left side of the cleaner station (300).

The third outer wall surface (312c) or the fourth outer wall surface (312d) may be formed in a flat shape, or may be formed in an entirely curved shape, or may be formed by including a curved surface in a portion.

Meanwhile, it is also possible to add a structure for mounting various types of cleaning modules (290) used in the cleaner (200) to the third outer wall surface (312c) or the fourth outer wall surface (312d).

The upper surface (313) may form the upper exterior of the cleaner station. That is, the upper surface (313) may mean a surface that is positioned at the uppermost side in the direction of gravity in the cleaner station and is exposed to the outside.

For reference, in this embodiment, the upper and lower sides may mean the upper and lower sides, respectively, along the direction of gravity (the direction perpendicular to the ground) when the cleaner station (300) is installed on the ground.

At this time, the upper surface (313) may be arranged parallel to the ground, but may also be arranged at a certain angle with the ground.

A display unit may be placed on the upper surface (313). For example, the display unit may display the status of the cleaner station (300) and the status of the cleaner (200), and may also display information such as the cleaning progress status and a map of the cleaning area.

Meanwhile, according to an embodiment, the upper surface (313) may be provided to be detachable from the outer wall surface (312). At this time, when the upper surface (313) is detached, the internal space surrounded by the outer wall surface (312) may accommodate a battery detached from the cleaner (200), and a terminal (not shown) capable of charging the detached battery may be provided.

FIG. 5 is a drawing for explaining a coupling part in a cleaning station according to one embodiment of the present invention.

Referring to FIG. 5, the cleaner station (300) may include a coupling part (320) for coupling the cleaner (200). Specifically, the coupling part (320) is arranged on the first outer wall surface (312a), and the dust bin (220) of the cleaner (200) may be coupled thereto. The main body (210) and the battery housing (230) of the cleaner (200) may also be coupled to the coupling part (320) together with the dust bin (220).

The coupling portion (320) may include a coupling surface (321). The coupling surface (321) may be arranged on a side surface of the housing (310). For example, the coupling 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). In other words, the coupling surface (321) may refer to a surface formed by forming a single unit with the first outer wall surface (312a).

A vacuum cleaner (200) may be coupled to the coupling surface (321). For example, the coupling surface (321) may be in contact with the lower surface of the dust bin (220) and the battery housing (230) of the vacuum cleaner (200). Here, the lower surface may mean a surface facing the ground when a user uses the vacuum cleaner (200) or places it on the ground.

For example, the angle formed by the joining 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 joined to the joining surface (321).

As another example, the joining surface (321) may be arranged to be inclined at a predetermined angle with respect to the ground. Through this, when the cleaner (200) is joined to the joining surface (321), the cleaner station (300) may be stably supported.

A dust passage hole (321a) may be formed in the coupling surface (321) to allow air from the outside of the housing (310) to flow 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 flow into the dust collection unit (370). 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 a flow path (380) to be described later (see FIG. 8).

The coupling portion (320) may include a dustbin guide surface (322). The dustbin guide surface (322) may be arranged on the first outer wall surface (312a). The dustbin guide surface (322) may be connected to the first outer wall surface (312a). In addition, the dustbin guide surface (322) may be connected to the coupling surface (321).

The dustbin guide surface (322) can be formed in a shape corresponding to the outer surface of the dustbin (220). The front outer surface of the dustbin (220) can be coupled to the dustbin guide surface (322). Through this, the convenience of coupling the vacuum cleaner (200) to the coupling surface (321) can be provided.

Meanwhile, a projection moving hole (322a) may be formed in the dustbin guide surface (322), and a push projection (351), which will be described later, may be linearly moved along the projection moving hole (322a) (see FIG. 11). 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 dustbin guide surface (322) in the gravity direction. At this time, a guide space (322b), in which the push projection (351) may be moved, may be formed between the dustbin guide surface (322), the lower side, and the upper side of the gear box (355). In addition, the guide space (322b) may be communicated with the first flow path (381) through the 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 connecting portion (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 coupling portion (320) may include a guide protrusion (323). The guide protrusion (323) may be arranged on the coupling surface (321). The guide protrusion (323) may protrude upward from the coupling surface (321). The guide protrusions (323) may be arranged two at a distance 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 coupling the cleaner (200) to the coupling surface (321) may be provided.

The coupling part (320) may include a coupling part side wall (324). The coupling part side wall (324) may refer to a wall surface arranged on both sides of the coupling surface (321) and may be vertically connected to the coupling surface (321). The coupling part side wall (324) may be connected to the first outer wall surface (312a). In addition, the coupling part side wall (324) may form a surface connected to the dustbin guide surface (322). Through this, the vacuum cleaner (200) may be stably accommodated.

The coupling unit (320) may include a coupling sensor. The coupling sensor may detect whether the cleaner (200) is coupled to the coupling unit (320).

The coupling sensor may also include a contact sensor. For example, the coupling sensor may include a micro switch. In this case, the coupling 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), the coupling sensor comes into contact, and the coupling sensor can detect that the cleaner (200) is coupled.

Meanwhile, the coupling sensor may also include a non-contact sensor. For example, the coupling sensor may include an infrared sensor (IR sensor). In this case, the coupling sensor may be placed on the coupling side wall (324). Accordingly, when the dust bin (220) or the main body (210) of the cleaner (200) passes the coupling side wall (324) and reaches the coupling surface (321), the coupling sensor may detect the presence of the dust bin (220) or the main body (210).

When the cleaner (200) is coupled to the cleaner station (300), the coupling sensor may face the dust bin (220) or battery housing (230) of the cleaner (200).

The coupling sensor can be a means for determining whether the vacuum cleaner (200) is coupled along with power being supplied to the battery (240) of the vacuum cleaner (200).

The coupling portion (320) may include a suction portion guide surface (326). The suction portion guide surface (326) may be arranged on the first outer wall surface (312a). The suction portion guide surface (326) may be connected to the dustbin guide surface (322). The suction portion (212) may be coupled to the suction portion guide surface (326). The shape of the suction portion guide surface (326) may be formed in a shape corresponding to the shape of the suction portion (212).

The joint part (320) may further include a fixed member entry/exit hole (327). The fixed member entry/exit hole (327) may be formed in the shape of a long hole along the side wall (324) of the joint part so that the fixed member (331) can enter/exit.

With this configuration, when a user attaches the cleaner (200) to the attachment portion (320) of the cleaner station (300), the main body (210) of the cleaner (200) can be stably placed on the attachment portion (320) by the dustbin guide surface (322), the guide protrusion (323), and the suction portion guide surface (326). Through this, the convenience of attaching the dustbin (220) and the battery housing (230) of the cleaner (200) to the attachment portion (321) can be provided.

Meanwhile, the cleaner station (300) may further include a charging unit (328). The charging unit (328) may be placed in the coupling unit (320). The charging unit (328) may be electrically connected to a cleaner (200) coupled to the coupling unit (320). The charging unit (328) may supply power to the battery of the cleaner (200) coupled to the coupling unit (320).

Additionally, the cleaner station (300) may further include a side door. The side door may be positioned in the housing (310). The side door may selectively expose the dust collection unit (370) to the outside. This allows the user to easily remove the dust bag (372) from the cleaner station (300).

FIG. 6 is a drawing for explaining a fixed unit in a cleaner station according to one embodiment of the present invention.

Referring to FIG. 6, the cleaner station (300) of the present invention may include a fixing unit (330). The fixing unit (330) may be disposed on a side wall (324) of a coupling portion. In addition, the fixing unit (330) may be disposed on the back surface of a coupling surface (321). The fixing unit (330) may fix a cleaner (200) coupled to the coupling surface (321). Specifically, the fixing unit (330) may fix a dust bin (220) and a battery housing (230) of the cleaner (200) coupled to the coupling surface (321).

The fixed unit (330) may include a fixed member (331) that fixes the dust bin (220) and the battery housing (230) of the vacuum cleaner (200), and a fixed member motor that drives the fixed member (331). In addition, the fixed unit (330) may further include a fixed member link (335) that transmits the power of the fixed member motor to the fixed member (331).

The fixed member (331) is arranged on the side wall (324) of the joint portion and may be provided to reciprocate on the side wall (324) of the joint portion to fix the dust bin (220). Specifically, the fixed member (331) may be accommodated inside the fixed member access hole (327).

The fixed members (331) can be arranged on each side of the joint (320). For example, two fixed members (331) can be arranged symmetrically in pairs around the joint surface (321).

The fixed member motor can provide power to move the fixed member (331).

The fixed link (335) can convert the rotational power of the fixed motor into reciprocating movement of the fixed member (331).

The fixed sealer (336) can be placed on the dustbin guide surface (322) to seal the dustbin (220) when the cleaner (200) is combined. With this configuration, when the dustbin (220) of the cleaner (200) is combined, the fixed sealer (336) can be pressurized by the weight of the cleaner (200), and the dustbin (220) and the dustbin guide surface (322) can be sealed.

The fixed sealer (336) can be placed on an imaginary extension of the fixed member (331). With this configuration, when the fixed member motor is operated and the fixed 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 fixed sealer (336) may be placed on the dustbin guide surface (322) in a bent line shape corresponding to the arrangement of the cover opening unit (350) described later.

Accordingly, when the main body (210) of the cleaner (200) is placed in the coupling portion (320), the fixing unit (330) can fix the main body (210) of the cleaner (200). Specifically, when the coupling sensor (325) detects that the main body (210) of the cleaner (200) is coupled with the coupling portion (320) of the cleaner station (300), the fixing portion motor can move the fixing member (331) to fix the main body (210) of the cleaner (200).

This can improve the suction power of the vacuum cleaner by preventing residual dust from remaining in the dust bin. In addition, it can eliminate unpleasant odors caused by residual dust by preventing residual dust from remaining in the dust bin.

FIG. 7 and FIG. 8 are drawings for explaining the relationship between a cleaner and a door unit in a cleaner station according to one embodiment of the present invention. FIG. 7 is a drawing illustrating a state in which a door closes a dust passage hole, and FIG. 8 is a drawing illustrating a state in which a door opens a dust passage hole.

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

The door unit (340) may include a door (341), a door motor (342), and a door arm (343).

The door (341) is hingedly connected to the joining surface (321) and can open and close the dust passage hole (321a). The door (341) may include a door body (341a).

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 part may be arranged on the upper side of the door body (341a), and a female coupling part (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 protrudingly on the inner surface to connect the hinge portion and the arm joint portion (341b) and to strengthen the supporting force of the door body (341a).

The hinge portion may be a means for hinge-connecting the door (341) to the joining surface (321). The hinge portion may be arranged at the upper end of the door body (341a) and may be connected to the joining surface (321).

The arm coupling part (341b) may be a means by which the door arm (343) is rotatably coupled. The arm coupling part (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 about the hinge part to move toward the inside of the cleaner station (300), and the dust passage hole (321a) can be opened. On the other hand, when the door arm (343) pushes the door body (341a) while the dust passage hole (321a) is open, the door body (341a) rotates about the hinge part (341b) to move toward the outside of the cleaner station (300), 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 (220) is separated from the dustbin body (210), the door (341) can come into contact with the discharge cover (220). And, as the door (341) rotates, the discharge cover (220) 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 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 a 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. Additionally, 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 vacuum 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 part (341b), and the door (141) that rotates relative to the hinge part (341b) can push the discharge cover (222) toward the dust bin body (221).

FIG. 9 is a drawing for explaining the relationship between a cleaner and a cover opening unit in a cleaner station according to one embodiment of the present invention.

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 coupling portion (320) and may open the discharge cover (222) of the cleaner (200).

The cover opening unit (350) may include a push projection (351), a cover opening motor (352), a cover opening gear (353), and a gear box (355).

The push lug (351) can be moved to pressurize the coupling lever (222c) when the vacuum cleaner (200) is coupled.

The push projection (351) can be placed on the dustbin guide surface (322). Specifically, a projection moving hole can be formed on the dustbin guide surface (322), and the push projection (351) can pass through the projection moving hole and be exposed to the outside.

The push projection (351) can be positioned at a position where the coupling lever (222c) can be pressed when the cleaner (200) is coupled. That is, the coupling lever (222c) can be positioned on the projection moving hole. In addition, the coupling lever (222c) can be positioned on the moving area of the push projection (351).

The push projection (351) can move linearly back and forth to pressurize the coupling lever (222c). Specifically, the push projection (351) can be coupled to a gear box (355) so that the linear movement can be guided. The push projection (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 projection (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 projection (351) presses the engaging lever (222c). In addition, the reverse direction may mean the direction in which the push projection (351) that has pressed the engaging 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 projection (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 projection (351) to move the push projection (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 equipped with a torsion spring (222d). The discharge cover (222) may be rotated by a predetermined angle or more by the elastic force of the torsion spring (222d), and may be supported at the rotated position. Accordingly, the discharge cover (222) may be opened, and may communicate the dust passage hole (321a) and the inside of the dust bin (220).

The gear box (355) is provided inside the housing (310) and is positioned below the gravity direction of the coupling part (320), and the cover opening gear (353) can be accommodated inside.

According to the present invention, the user can open the dust bin (220) without separately opening the discharge cover (222) of the vacuum cleaner by using the cover opening unit (350), thereby improving convenience.

In addition, since the discharge cover (222) is opened while the cleaner (200) is connected to the cleaner station (300), there is an effect of preventing dust from flying.

FIG. 10 is a drawing illustrating the arrangement of a dust collection unit and a dust suction module accommodated inside a housing in a cleaner station according to one embodiment of the present invention, FIG. 11 is a drawing for explaining the arrangement of a flow path section and the flow of suction air flowing through the flow path section in a cleaner station according to one embodiment of the present invention, FIG. 12 is an enlarged view of the dust collection unit illustrated in FIG. 10, and FIG. 13 is a cross-sectional perspective view of the dust collection unit illustrated in FIG. 10.

Referring to FIGS. 10 to 12, the cleaner station (300) may include a dust collection unit (370). The dust collection unit (370) may be placed inside the housing (310). The dust collection unit (370) may be placed below the gravity direction of the coupling unit (320). And the dust collection unit (370) may be placed above the gravity direction of the dust collection motor (391).

The dust collection unit (370) can collect dust inside the dust bin (220) of the vacuum cleaner (200). Specifically, when the vacuum cleaner (200) is connected to the vacuum cleaner station (300) and the inside of the dust bin (220) and the flow path (380) are connected, when the dust collection motor (391) is operated, dust inside the dust bin (220) can flow along the flow path (380) and be collected by the dust collection unit (370).

The dust collection unit (370) may include a dust separation unit (371), a dust bag (372), a bag support unit (373), and a dust bag cartridge (374).

The dust separation unit (371) can separate dust from the air flowing in from the dust bin (220).

The dust separation unit (371) may be positioned above the dust bag (372), bag support unit (373), dust bag cartridge (374), and jointer (376). The dust separation unit (371) may be positioned on the longitudinal axis (C) of the cleaner station (300).

The dust separation unit (371) can be communicated with the first passage (381). The dust separation unit (371) can separate dust sucked into the inside through the first passage (381). The space inside the dust separation unit (371) can be communicated with the space inside the bag support unit (373).

One embodiment of the dust separation unit (371) may be a configuration in which the principle of a dust collector that uses centrifugal force is applied to separate dust that has entered the interior of the housing (310) through the dust passage hole (321a) and the first flow path (381).

The dust bag (372) can be placed inside the housing (310). The dust bag (372) can be placed below the gravity direction of the dust separation unit (371).

The dust bag (372) may be formed of an impermeable material. For example, the dust bag (372) may be made of a vinyl material, such as a roll vinyl. Due to the material characteristics of the dust bag (372), dust or odors captured inside may be prevented from leaking out of the dust bag (372).

The dust bag (372) can be mounted on the housing (310) through the dust bag cartridge (374). If necessary, the dust bag (372) can be replaced through the dust bag cartridge (374). That is, the dust collection unit (370) can be defined as a consumable part. The dust bag (372) can increase in volume due to the suction force (negative pressure) generated when the dust collection motor (391) operates while it is mounted on the housing (310).

The dust bag (372) inserted in a roll or laminated form into the dust bag cartridge (374) is spread to form a volume in the shape of a pocket by the suction force of the dust collection motor (391). The dust bag (372) can be used by storing dust inside it and then cutting and joining it and discarding it.

At this time, the dust bag (372) in the unfolded state can be accommodated in the internal space of the bag support member (373). That is, when the dust collection motor (391) is operated, the dust bag (372) can be expanded in the internal space of the bag support member (373).

The dust bag (372) can store dust separated from the dust separation unit (371). The dust bag (372) can have its upper region cut and joined by a jointer (376). The dust bag (372) can be separated from the bag support unit (373) in a state where its upper region is cut and joined.

This configuration improves user convenience as the user does not need to separately bundle the dust-collecting bag.

The bag support (373) can support the dust bag (372). When the dust bag (372) is inflated, the bag support (373) can accommodate the dust bag (372) in the internal space. The bag support (373) can support the outer shape of the inflated dust bag (372).

The bag support member (373) may be positioned on the lower side of the dust separation member (371) in an open top form. With this configuration, dust separated from the dust separation member (371) may be dropped and captured by the load into the dust bag (372) inside the bag support member (373).

The bag support member (373) may be positioned on the lower side of the dust bag cartridge (374). With this configuration, when the dust bag (372) is expanded downward from the dust bag cartridge (374), at least a portion of the dust bag (372) may be accommodated in the internal space of the bag support member (373).

The bag support member (373) may be placed on the lower side of the jointer (376). With this configuration, the inflated dust bag (372) is joined and cut by the jointer (376), and the cut dust bag (372) may be accommodated in the bag support member (373) while falling by gravity. Accordingly, the user may take out the dust bag (372) with the upper part completely joined and closed while the dust is stored inside it and throw it away outside the housing (310). Accordingly, the user does not have to worry about dust flying when handling the dust bag (372), so that convenience is improved.

Meanwhile, the envelope support member (373) may be provided so as to be withdrawable from the internal space of the housing (310).

Specifically, the envelope support member (373) may be provided with a structure that guides the linear movement of the envelope support member (373). As a possible example, a plurality of wheels may be provided at the lower portion of the envelope support member (373) so that the wheels can pull the envelope support member (373) out of the housing (310). As another possible example, a guide rail may be formed on the upper surface or side of the envelope support member (373) so that the envelope support member (373) can be pulled out of the housing (310) in a sliding manner.

With this configuration, the user can open the side door (not shown) of the cleaner station (300) and then pull the bag support member (373) to pull the dust bag (372) out of the housing (310). Therefore, according to the present invention, the user can easily take out and throw away the dust bag.

A dust bag cartridge (374) is detachably coupled to the housing (310) and can supply a dust bag (372).

The dust bag cartridge (374) can be detachably coupled to the housing (310). Although not shown, a structure in which the dust bag cartridge (374) is coupled can be formed inside the housing (310), and the user can insert the dust bag cartridge (374) into the inside of the housing (310). In addition, when the dust bag cartridge (374) is coupled to the housing (310), if the user pulls the dust bag cartridge (374) toward the outside of the cleaner station (300), the dust bag cartridge (374) can be separated from the housing (310). With this configuration, the user can easily mount or detach the dust bag cartridge (374) to or from the housing.

The dust bag cartridge (374) may be equipped with a dust bag (372). For example, at least a part of a dust bag (372) in a roll shape may be combined with the dust bag cartridge (374), and the dust bag (372) may be expanded toward the bag support member (373) according to the operation of the dust collection motor (391). In addition, when the dust bag (372) is combined according to the operation of the jointer (376), a part of the dust bag (372) may be separated from the dust bag cartridge (374). With this configuration, since the user does not need to separately bundle a bag containing dust, etc., the user convenience may be improved.

The dust bag cartridge (374) may be placed on the lower side of the dust separation unit (371). For example, the upper side of the dust bag cartridge (374) may be in contact with the lower side of the dust separation unit (371). At this time, a sealer that blocks the leakage of foreign substances may be provided on the upper side of the dust bag cartridge (374) and/or the lower side of the dust separation unit (371). With this configuration, foreign substances separated from the dust separation unit (371) may be captured inside the dust bag (372) without leaking to the outside.

The dust bag cartridge (374) may be placed on the upper side of the jointer (376). For example, the lower side of the dust bag cartridge (374) may be in contact with the upper side of the jointer (376). At this time, a sealer may be provided on the lower side of the dust bag cartridge (374) and/or the upper side of the jointer (376) to block the leakage of foreign substances. With this configuration, when the dust bag (372) is joined and separated, it is possible to prevent foreign substances on the flow path (380) from leaking between the dust bag cartridge (374) and the jointer (376).

The dust collection unit (370) may further include a pre-filter (379).

The prefilter (379) may be placed between the dust separation unit (371) and the second passage (382). Alternatively, the prefilter (379) may be placed on the second passage (382). The prefilter (379) may separate and filter foreign substances from air flowing through the dust separation unit (371) to the second passage (382).

With this configuration, there is an effect of preventing fine foreign substances from entering the dust collection motor (391).

The prefilter (379) can be detachably coupled to the interior of the second flow path (382). For example, a prefilter insertion part (379a) is provided at the front end of the second flow path (382), and the prefilter (379) can be inserted or withdrawn into the prefilter insertion part (379a) (see FIG. 13). At this time, a plurality of holes can be formed in the prefilter insertion part (379a) so that air passing through the prefilter (379) flows into the second flow path.

The dust collection unit (370) may further include a joint (376).

The connector (376) may be placed in the housing (310). For example, the connector (376) may be fixedly connected to the housing (310).

The connector (376) may be placed on the lower side of the dust bag cartridge (374). For example, the upper side of the connector (376) may be in contact with the lower side of the dust bag cartridge (374). With this configuration, the connector (376) may guide the detachment of the dust bag cartridge (374). Meanwhile, a sealer may be provided between the upper side of the connector (376) and the lower side of the dust bag cartridge (374) to prevent foreign substances from leaking.

The joint (376) may be placed on the upper side of the envelope support (373). For example, the lower side of the joint (376) may be in contact with the upper side of the envelope support (373). At this time, a sealer may be provided between the lower side of the joint (376) and the upper side of the envelope support (373) to prevent foreign substances from leaking.

The jointer (376) can cut and join the upper region of the dust bag (372) where dust is collected. Specifically, the jointer (376) can gather the dust into the central region of the dust bag (372) and hot-wire join the upper region of the dust bag (372). For example, the jointer (376) can include a first joint member (not shown) and a second joint member (not shown). The first joint member (not shown) can move in a first direction through a first joint driving unit, and the second joint member (not shown) can move in a second direction perpendicular to the first direction through a second joint driving unit.

With this configuration, dust collected from the outside can be collected inside the plastic bag, and the plastic bag can be automatically joined. Therefore, the user does not need to separately tie the bag containing the dust, which improves user convenience.

Meanwhile, the dust collection unit (370) may further include a dust amount sensor.

The dust amount sensor can measure the amount of dust inside the dust bag (372). In a possible embodiment, when the amount of dust measured by the dust amount sensor reaches a predetermined amount, the jointer (376) can be automatically operated to cut and joint the dust bag (372).

The cleaner station (300) may include a euro section (380).

The euro part (380) can connect the vacuum cleaner (200), the dust collection part (370), and the dust collection motor (391). The euro part (380) can include a first euro part (381) and a second euro part (382).

The first flow path (381) can connect the dust bin (220) of the cleaner (200) and the dust separation unit (371). The first flow path (381) can be arranged at the rear side of the coupling surface (321). The first flow path (381) can mean a space formed between the dust bin (220) of the cleaner (200) and the dust separation unit (371) so that air can flow. For example, the first flow path (381) can be a space formed by being surrounded by a structure. For example, the first flow path (381) can be an internal space of a hollow tube.

The first euro (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 separation unit (371). (See FIG. 8)

At this time, the direction in which the first region (381a) is formed may be arranged substantially parallel to the axial direction (length direction) of the dust bin (220). In addition, the direction in which the second region (381b) is formed may be arranged in a direction parallel to the length direction axis line (C) of the housing (310). At this time, the first region (381a) may be formed at a predetermined angle with the second region (381b). With this configuration, the suction power of the dust collecting motor (391) can be minimized from being reduced in the first flow path (381) and the second flow path (382).

Therefore, when the dust collecting motor (391) is operated, dust in the dust bin (220) of the cleaner (200) can flow to the dust separation unit (371) through the first duct (381).

The second flow path (382) can connect the dust separation unit (371) and the dust suction module (390). That is, the air from which dust has been separated while passing through the dust separation unit (371) 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 separation unit (371) and the dust suction module (390) to allow air to flow. The second flow path (382) may be formed while being surrounded by a structure. A portion of the second flow path (382) may be formed by the bag support member (373). The second flow path (382) formed in the bag support member (373) may be arranged on the side of the bag support member (373).

As will be described later, by simply forming an air hole (373b) through the envelope support member (373) through this arrangement, the movement path of a portion of the suction air flowing in the second path (373) can be bypassed.

In the present invention, the path of suction air flowing to the dust collecting motor (391) only through the duct section (380) is defined as the main suction path (MP), and the path of suction air flowing to the dust collecting motor (391) through the duct section (380) and the interior of the bag support section (373) is defined as the bypass suction path (BP1, BP2). This will be described later.

With this configuration, there is an effect of operating the dust collecting motor (391) to expand the dust bag and maintain the expanded shape.

The vacuum station (300) may include a dust suction module (390).

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 unit (370). The dust collection motor (391) may generate suction force in the duct unit (380). Through this, suction force capable of sucking dust into the dust bin (220) of the vacuum cleaner (200) is provided.

The dust collecting motor (391) can generate suction force by rotation. For example, the dust collecting motor (391) can be formed in a shape similar to a cylinder and can generate suction force while rotating around a rotation axis. At this time, the direction of the rotation axis of the dust collecting motor (391) can be arranged perpendicular to the ground.

FIG. 14 is a perspective view showing an exploded view of a dust separation unit and a bag support unit in a cleaner station according to one embodiment of the present invention.

Referring to Fig. 14, the dust separation unit (371) may be provided with at least one cyclone unit (371a) capable of separating dust by cyclone flow. Accordingly, air and dust flowing in through the first flow path (381) flow in a spiral manner along the inner surface of the dust separation unit (371). Accordingly, cyclone flow may occur in the inner space of the dust separation unit (371).

Meanwhile, in the present embodiment, the cyclone part (371a) may be provided with a cylindrical mesh net. Here, the axial direction of the mesh net may be arranged parallel to the ground. With this configuration, when the cyclone part (371a) is pulled from the side of the cleaner station (300), it can be separated from the dust collection part (370). Therefore, according to the present embodiment, a user can easily separate the cyclone part (371a) and wash the mesh net.

In addition, the dust separation unit (371) may include a dust passage pipe (371b) that guides dust separated from the cyclone unit (371a) to a dust bag (372). The dust passage pipe (371b) may be formed downward on one axial side of the cyclone unit (371a). In addition, the dust passage pipe (371b) may be open at both axial ends to connect the internal space of the cyclone unit (371a) and the bag support unit (373).

The dust separation unit (371) may further include a secondary cyclone that separates dust again from the air discharged from the cyclone unit (371a). At this time, the secondary cyclone may be positioned inside the cyclone unit (371a) so that the size of the dust separation unit (371) is minimized. The secondary cyclone may include a plurality of cyclone bodies arranged in parallel.

Since the bag support part (373) is open at the top and communicates with the cyclone part (371a), dust separated from the air by the cyclone flow falls to the dust bag (372). (Path of the dashed-dotted arrow in Fig. 14) At this time, the intake air moves to the second flow path (382) through the dust separation part (373) via the first flow path (381) by the suction force of the dust collection motor (391). (Path of the solid-line arrow in Fig. 14)

FIG. 15 is a perspective view of an envelope support portion in a cleaner station according to one embodiment of the present invention, and FIG. 16 is a cross-sectional perspective view for explaining the internal structure of an envelope support portion in a cleaner station according to one embodiment of the present invention.

Referring to FIGS. 15 and 16, in an embodiment of the present invention, the bag support member (373) can provide an bag receiving space to receive a dust bag (372) therein. The upper part of the bag support member (373) is open and is positioned lower than the dust separation member (371), so that dust separated from the dust separation member (371) can fall into the bag receiving space of the bag support member (373).

The envelope support (373) may include a support body (373a), an air hole (373b), and a support outer wall (373c).

The outer wall (373c) of the support portion forms the outer appearance of the bag support portion (373). For example, the outer wall (373c) of the support portion may be generally hexahedral. A portion of the front surface of the outer wall (373c) of the support portion may be opened for taking out the dust bag (372). A portion of the upper surface or the entire upper surface of the outer wall (373c) of the support portion may be opened in a direction facing the dust separation portion (371).

The support body (373a) is arranged inside the support outer wall (373c). The support body (373a) forms a space between itself and the support outer wall (373c). The space formed outside the support body (373a) may form a part of the second flow path (382). The space formed inside the support body (373a) may be defined as the envelope receiving space described above.

More specifically, the support body (373a) may include a body side wall (373aa) and a body bottom wall (373ab). The body side wall (373aa) may be arranged parallel to the longitudinal axis (C) of the housing (310), and the body bottom wall (373ab) may be connected to the body side wall (373aa) and arranged perpendicular to the longitudinal axis (C) of the housing (310).

In the case where the main body side wall (373aa) is provided on only one side, as in the embodiment illustrated in Fig. 16, the support main body (373a) and the support outer wall (373c) can together form the outer appearance of the envelope receiving space.

Alternatively, in another possible embodiment, the main body side walls (373aa) may be provided in all directions of the front, back, left, and right so that the support main body (373a) may form the outer appearance of the bag receiving space on its own. In this case, a portion of the main body side walls (373aa) positioned in the front may be opened to allow the dust bag (372) to be pulled out of the housing (310).

An air hole (373b) is formed in the support body (373a). The air hole (373b) is formed so as to penetrate the support body (373a). As a result, the bag receiving space and the second flow path (382) can be connected, and when the dust collecting motor (391) is driven, a portion of the intake air flowing to the second flow path (382) can be introduced into the bag receiving space.

Air holes (373b) can be formed in each of the main body side wall (373aa) and the main body bottom wall (373ab). A plurality of air holes (373b) can be formed. The suction force of the dust collecting motor (391) is applied downward, and the suction air passes through the air holes (373b) of the main body side wall (373aa) from the second flow path (382) into the bag receiving space and exits through the air holes (373b) of the main body bottom wall (373ab).

That is, the air hole (373b) formed in the support body (373a) serves to bypass the flow of intake air flowing through the duct section (380) from the main intake path (MP).

Here, the main suction path (MP) is a path of suction air flowing directly from the second path (382) to the dust collecting motor (391). In the embodiment of the present invention, the number of air holes (373b) formed in the main body side wall (373aa) is smaller than the number of air holes (373b) formed in the main body bottom wall (373ab). As a result, more air escapes from the bag receiving space to the second path (382) than air flows into the bag receiving space from the second path (382).

By the above-described configuration, when the dust collecting motor (391) is driven, a negative pressure is formed in the bag receiving space that expands the dust bag (372). That is, the dust bag is automatically expanded by the driving of the dust collecting motor without the user having to manually unfold the dust bag, so there is an advantage of improved user convenience.

The cleaner station (300) according to an embodiment of the present invention may further include a partition (375) arranged inside the bag support (373). The partition (375) is configured to divide the bag receiving space into a first space (S1) and a second space (S2).

More specifically, the partition (375) includes a partition side wall (375a) that is arranged at a predetermined distance from the main body side wall (373aa) toward the inside of the envelope receiving space, but is arranged parallel to the main body side wall (373aa). The partition (375) further includes a partition bottom wall (375b) that is arranged at a predetermined distance from the main body bottom wall (373ab) toward the inside of the envelope receiving space, but is arranged parallel to the main body bottom wall (373ab). The partition side wall (375a) and the partition bottom wall (375b) are connected to each other. Through this configuration, the envelope receiving space is divided and partitioned into a first space (S1), which is an inner space, and a second space (S2), which is an outer space, with the partition (375) therebetween.

The partition (375) includes an air hole (375c) formed to connect the second space (S1) and the first space (S1). The air hole (375c) is formed to penetrate the partition side wall (375a). The air hole (375c) is formed to penetrate the partition bottom wall (375b). The air hole (375c) of the partition (375) can be arranged at a position corresponding to the air hole (375b) of the support body (373a). The number of air holes (375c) of the partition (375) can correspond to the number of air holes (375b) of the support body (373a).

FIG. 17 is a cross-sectional perspective view showing the movement path of suction air in an envelope support section in a cleaner station according to one embodiment of the present invention.

When the dust collecting motor (391) is driven, negative pressure is simultaneously formed in the first space (S1) and the second space (S2) by the air flow through the air holes (373b, 375c). Some of the intake air of the second flow path (382) can pass through the second space (S2) and the first space (S1) and be guided to the dust collecting motor (391). (BP1, dotted arrow path in FIG. 17) Some of the intake air of the second flow path (382) can pass through only the second space (S2) and be guided to the dust collecting motor (391). (BP2, dashed arrow path in FIG. 17)

All of the above movement paths are defined as bypass suction paths in that they are movement paths that bypass the main suction path (MP, solid arrow path in Fig. 17).

At this time, the bypass suction path connected to the second flow path (382), the second space (S2), the first space (S1), and the dust collecting motor (391) may be defined as the first bypass suction path (BP1). In contrast, the bypass suction path connected to the second flow path (382), the second space (S2), and the dust collecting motor (391) may be defined as the second bypass suction path (BP2).

That is, the partition (375) serves to divide the bypass suction path through which the suction air moves when the dust collector motor (391) is driven into two different paths. This prevents the phenomenon of the inflated dust bag (372) flowing backward toward the dust separation unit (371). Before explaining this, the dust bag backflow phenomenon in the case where the partition (375) is not provided will be explained below.

Figures 18 to 20 are schematic diagrams for explaining the dust bag backflow phenomenon when the compartment is not arranged in the bag support.

As illustrated in Fig. 18, the suction air moves to the bypass suction path (BP) through the air hole (373b) formed in the support body (373a), and a negative pressure is formed in the bag receiving space. The dust bag (372) expands due to the negative pressure, and the expanded dust bag (372) is supported by the inner surface of the support body (373a). When the dust bag (372) expands to the maximum and is attached to the inner surface of the support body (373a) as illustrated in Fig. 19, the air hole (373b) of the support body (373a) is blocked by the dust bag (372), and a phenomenon occurs in which the inflow and outflow of air is blocked.

That is, the flow of air through the bypass suction path (BP) is blocked and the suction air flows only to the main suction path (MP), so the overall flow rate directed to the dust collection motor (391) decreases. The decrease in the flow rate guided to the dust collection motor (391) means a relative increase in the flow rate escaping from the dust separation unit (371). In addition, if the bypass suction path (BP) is blocked due to blockage of the air hole (373b), the force for expanding the dust bag (372) also becomes weaker.

For the reasons mentioned above, as shown in Fig. 20, a phenomenon occurs in which the dust bag (372) partially flows backwards toward the top. This may lead to a deterioration in the performance of the dust separation unit (371). Alternatively, if the backward-flowing dust bag (372) gets stuck in parts such as the dust bag cartridge (374) or the coupler (376), it may cause a failure of the dust bag cartridge (374) or the coupler (376).

Now again, referring to FIGS. 16 and 17, the intake air flow in the case where the partition (375) is arranged as in the embodiment of the present invention will be described.

Since the partition (375) is positioned at a predetermined distance from the support body (373a) toward the inside of the envelope receiving space, a separation space (second space (S2)) through which air can flow is formed between the partition (375) and the support body (373a).

When defining the direction of the second space (S2) as one side and the direction of the first space (S1) as the other side based on the partition (375), the partition (375) supports the outer shape of the inflated dust bag (372) from the other side so as not to obstruct the air flow of the second space (S2) arranged on one side.

In other words, the expansion of the dust bag (372) is blocked by the compartment (375). The dust bag (372) is supported while expanding along the other side of the compartment (375). From another perspective, the dust bag (372) expands along the arrangement shape of the compartment (375).

The air inlet and outlet of the air hole (375c) of the compartment (375) can be blocked by the expansion of the dust bag (372). Accordingly, the air flow of the first bypass suction path (BP1) is maintained or blocked depending on the degree of expansion of the dust bag (372).

At this time, since the dust bag (372) is supported by the partition (375), the air flow in the air hole (373b) of the support body (373a) is not blocked. Accordingly, the air flow in the second bypass suction path (BP2) is constantly maintained regardless of the degree of expansion of the dust bag (372).

Figures 21 and 22 are schematic diagrams for explaining the principle of preventing dust bag backflow phenomenon when a compartment is arranged in an envelope support.

Referring to FIGS. 21 and 22, even when the dust bag (372) is expanded to the maximum and the air hole (375c) of the compartment (375) is closed, air flow through the second bypass suction path (BP2) is maintained, so that a large flow rate reduction does not occur as shown in FIGS. 19 and 20.

Therefore, the flow rate guided to the dust collecting motor (391) is still relatively larger than the flow rate flowing out of the dust separator (371). This means that the force pulling the dust bag (372) downward is greater than the force pulling it upward, so that the occurrence of the backflow phenomenon of the dust bag (372) as shown in Fig. 20 can be suppressed.

As a result, the phenomenon of the backflowed dust bag (372) getting caught in parts such as the dust bag cartridge (374) and the jointer (376) and the failure of the dust bag cartridge (374) or the jointer (376) caused by this phenomenon are prevented in advance.

Although specific embodiments of the present invention have been described and illustrated above, it will be understood that the present invention is not limited to the described embodiments, and that those skilled in the art will appreciate that various modifications and variations can be made to other specific embodiments without departing from the spirit and scope of the present invention. Accordingly, the scope of the present invention should not be defined by the described embodiments, but should be defined by the technical idea set forth in the claims.
