Patent Description:
Generally, a cleaner is a household appliance which uses an electrical energy to suck small garbage or dust into a dust bin of the machine by inhaling air, and is generally called a vacuum cleaner.

Cleaners may be classified into a manual cleaner for cleaning while a user directly moves the machines, and an autonomous cleaner for cleaning while driving by itself. Manual cleaners may be classified into cannister vacuum cleaners, uplight cleaners, hand vacuum cleaners, and stick vacuum cleaners depending on the shape of the cleaners.

Traditionally cannister vacuum cleaners have been widely used as household vacuum cleaners, but in recent years, hand vacuum cleaners or stick vacuum cleaners, which have improved ease of use by providing a dust bin and cleaning body, are a trend.

In cannister vacuum cleaners a main body and an inlet are connected by a rubber hose or pipe, and in some cases a brush may be inserted into the inlet.

Hand Vacuum Cleaners can maximize portability, but, due to they are light in weight and short in length, so there may be restrictions on the area to sit and clean. Therefore, it is generally used for cleaning a local area such as a desk, a sofa or inside the car.

Stick vacuum cleaners can be used while standing, and thus a user can operate stick vacuum cleaners without bending her or his waste. Thus, it can be used for moving and cleaning a large area. While hand vacuum cleaners clean a small space, stick vacuum cleaners can clean a wider space than that, and can clean a high place out of reach. Recently, module type stick vacuum cleaners are provided, and such module types are actively changeable for cleaning various objects.

In addition, recently, robot cleaners that perform self-cleaning without a user's manipulation have been used. Robot cleaners automatically clean the area to be cleaned by inhaling foreign matters such as dusts from a floor while travelling on their own.

Robot cleaners include a distance sensor for sensing distances between obstacles such as furniture, office supplies or walls located in a cleaning area, and left and right wheels for moving the robot cleaners.

A left wheel and right wheel are configured to rotate by a left motor and right motor respectively, and the robot cleaners change directions by themselves and perform indoor cleaning according to the driving of the left and right wheel motors.

However, conventional hand vacuum cleaners, stick vacuum cleaners and robot cleaners have a small capacity of a dust bin for storing collected dust, so that a user has to empty the dust bin frequently.

Further dust can be scattered while discharging a dust bin, which may negatively affect a user's health.

Still further, the suction power of the vacuum cleaner may be lowered when a residual dust in a dust bin is not removed.

Still further, an odor can occur due to a residue when a residual dust in a dust bin is not removed.

However, in one embodiment of the present invention some of these components may be excluded or additional components may be included,
The dust removal system <NUM> may include a station <NUM>. The first cleaner <NUM> and the second cleaner <NUM> may be disposed to the station <NUM>. The first cleaner <NUM> may be coupled on the upper part of the station <NUM>. Particularly, on the upper part of the station <NUM>, the main body of the first cleaner <NUM> may be coupled.

A dust storage unit <NUM>, a first flow path <NUM>, a second flow path <NUM>, a valve <NUM> and an inspirator <NUM> may be disposed inside the housing <NUM>. In one embodiment of the present disclosure, the housing <NUM> is descried as being formed in a hexahedron shape as an example, but the shape of the housing <NUM> is not limited thereto, and the shape of the housing <NUM> may be variously changed.

The housing <NUM> may include a first door member <NUM>. The first door member <NUM> may be disposed on the upper surface of the housing <NUM>. The first door member <NUM> may selectively expose to an outside the coupling body <NUM> disposed on the upper part of the housing <NUM>. The first door member <NUM> may be opened when a user approaches the station <NUM>, and the first door member <NUM> may be closed when the first cleaner <NUM> coupled on the station <NUM> is separated from the station <NUM>. Accordingly, it is possible to prevent foreign matters such as dust from entering inside of the station <NUM>.

In one embodiment of the present specification, the predetermined angle of the coupling body <NUM> formed with the ground may be between <NUM> degrees and <NUM> degrees.

If the predetermined angle of the coupling body <NUM> formed with the ground is greater than <NUM> degrees, the inclination of the dust bin <NUM> is sever and there is a risk that the dust in the dust bin <NUM> remains due to gravity.

Preferably, the predetermined angle of the coupling body <NUM> formed with the ground may be between <NUM> degrees and <NUM> degrees. Considering the weight of the main body <NUM> of the first cleaner <NUM> and the average female body condition, if the predetermined angle of the coupling body <NUM> formed with the ground is less than <NUM> degrees, the user's wrist may be strained.

The coupling body <NUM> may include a coupling surface <NUM>. The coupling surface <NUM> may be disposed on the upper surface of the housing <NUM>. The first cleaner <NUM> may be coupled on the coupling surface <NUM>. Specifically, the main body <NUM> of the first cleaner <NUM> may be coupled on the coupling surface <NUM>. For example, the dust bin <NUM> of the first cleaner <NUM> may be disposed on the coupling surface <NUM>. The coupling surface <NUM> may form a predetermined angle with a ground. For example, an angle formed by the coupling surface <NUM> with the ground may be an acute angle. Accordingly, it is convenient that the main body <NUM> of the first cleaner <NUM> is coupled on the coupling surface <NUM>. Here, the coupling between the coupling surface <NUM> and the main body <NUM> of the first cleaner <NUM> may mean a physical coupling in which the first cleaner <NUM> and the station <NUM> are coupled and fixed.

The fixing part <NUM> may include a fixing member <NUM> fixing the main body <NUM> of the first cleaner <NUM> and a fifth driving unit <NUM> for driving the fixing member <NUM>. In an embodiment of the present invention, the fifth driving unit <NUM> is described as an example of moving the fixing member <NUM> up and down, but as long as the main body <NUM> of the first cleaner <NUM> is fixed to the coupling body <NUM>, the shape of the fixing member <NUM> and the type of the fifth driving unit <NUM> may be variously changed.

The fixing member <NUM> may be disposed on both sides of the bottom surface of the main body <NUM> of the first cleaner <NUM> coupled to the coupling body <NUM>. The width of the fixing member <NUM> may correspond to the width of the main body <NUM> of the first cleaner <NUM> or may be smaller than the width of the main body <NUM> of the first cleaner <NUM>. The fixing member <NUM> may be disposed on a second guide part <NUM>. Specifically, referring to <FIG>, <FIG>, <FIG>, the fixing member <NUM> may be disposed on a surface of the first and second guide members facing each other. Through this, the main body <NUM> of the first cleaner <NUM> guided by the second guide part <NUM> may be fixed in a correct position.

For example, the opening and closing member <NUM> may be rotated to one side by the third driving unit <NUM>. The opening and closing member <NUM> may close the body cover <NUM> of the first cleaner <NUM> by closing the opening and closing member <NUM>.

Unlike this, the opening and closing member <NUM> may be opened and closed based on a second rotation shaft <NUM> by a first driving unit (not shown). Through this, the dust bin <NUM> of the first cleaner <NUM> and the first flow path <NUM> may be coupled in a flow path so that a fluid flows.

The coupling body <NUM> may include a first driving unit (not shown). The first driving unit may be disposed in the housing <NUM>. The first driving unit may rotate the coupling surface <NUM>. When the dust bin <NUM> is coupled on the coupling surface <NUM>, the first driving unit may rotate the coupling surface <NUM> horizontally with a ground. Accordingly, it is possible to improve the collecting efficiency that the dust inside the dust bin <NUM> is collected by its own weight into the dust storage unit <NUM>.

When the dust bin <NUM> is coupled to the coupling body <NUM>, the first driving unit may rotate the coupling body <NUM> horizontally with the ground. Specifically, when the second sensing unit <NUM> detects that the coupling body <NUM> is coupled to the dust bin <NUM>, the first driving unit may rotate the coupling body <NUM> horizontally with the ground.

The station <NUM> may include a first rotation shaft <NUM>. The first rotation shaft <NUM> may be connected to the first driving unit.

When the first gear <NUM> is rotated in the other direction by the first driving unit, the second gear <NUM> may be rotated in the other direction by the first gear <NUM> to rotate the coupling body <NUM> in the other direction. Through this, the coupling body <NUM> may be disposed to form a predetermined angle with the ground.

Referring to <FIG>, when the first gear <NUM> is rotated in one direction by the first driving unit, the third gear <NUM> may rotate in the other direction by the first gear <NUM> to rotate the opening and closing member <NUM> in the other direction. Through this, the opening and closing member <NUM> may rotate to form a predetermined angle with the coupling surface <NUM>. When the first gear <NUM> rotates in the other direction by the first driving unit, the third gear <NUM> may rotate in one direction by the first gear <NUM> to rotate the opening and closing member <NUM> in one direction.

The shape of the third guide part <NUM> may be formed in a shape corresponding to the shape of the suction unit <NUM>. Through this, convenience in which the main body <NUM> of the first cleaner <NUM> is coupled to the coupling surface <NUM> may be provided.

The station <NUM> may include a separating unit <NUM>. When the coupling surface <NUM> forms a predetermined angle with a ground, the separating unit <NUM> may be disposed on an upper part of the coupling surface <NUM>.

The separating member <NUM> may protrude inward from the inner side surface of the station <NUM>. The separating member <NUM> may be disposed on the inner side surface of the coupling body <NUM>. The separating member <NUM> may protrude inward from the inner side surface of the coupling body <NUM>. The separating member <NUM> may be disposed on the second guide part <NUM>. The separating member <NUM> may protrude inward from the second guide part <NUM>.

<FIG> illustrate that a transmission member <NUM> is included as an example, but unlike this, the transmission member <NUM> may not be disposed between the second guide part <NUM> and the coupling lever <NUM>. In this case, when the coupling body <NUM> rotates in a direction horizontal to the ground, the coupling lever <NUM> of the first cleaner <NUM> may be directly caught by the separating member <NUM> and separated from the dust bin <NUM>. Through this, the body cover <NUM> is separated from the dust bin <NUM> so that the dust in the dust bin <NUM> may be moved to the dust storage unit <NUM>.

The separating unit <NUM> may include the transmission member <NUM>. The transmission member <NUM> may be formed on the coupling body <NUM>. The transmission member <NUM> may be formed on the coupling surface <NUM>. The transmission member <NUM> may rotate in one direction or the other direction like the coupling surface <NUM>. The transmission member <NUM> may be disposed between the separating member <NUM> and the coupling lever <NUM> of the first cleaner <NUM>. Specifically, one side of the transmission member <NUM> may be disposed under the separating member <NUM>, and the other side of the transmission member <NUM> may be disposed above the coupling lever <NUM>. In this case, the other side of the transmission member <NUM> may maintain a contacted state with the coupling lever <NUM> or may be maintained in a spaced state.

When the coupling body <NUM> rotates in a direction horizontal to the ground, the upper part or upper surface of one side of the transmission member <NUM> may contact the lower part or lower surface of the separating member <NUM>. In this case, the other side of the transmission member <NUM> may press the coupling lever <NUM> downward to separate the body cover <NUM> from the dust bin <NUM>.

The transmission member <NUM> may include a vertical portion connecting one side and the other side. When the coupling body <NUM> is disposed horizontally with the ground, the vertical portion of the transmission member <NUM> may extend in the vertical direction as shown in <FIG>. Through this, since the separating member <NUM> is disposed below the coupling surface <NUM> of the coupling body <NUM>, space efficiency inside the station <NUM> can be improved.

In addition, the vertical portion of the transmission member <NUM> may include a step portion in which a lower part is disposed adjacent to the separating member <NUM> than an upper part. Specifically, referring to <FIG>, the lower region of the vertical portion of the transmission member <NUM> may be disposed adjacent to the separating member <NUM> than the upper region of the vertical portion of the transmission member <NUM>. Through this, space efficiency inside the station <NUM> can be improved.

Since the body cover <NUM> is separated from the dust bin <NUM> through the separating unit <NUM> in a state in which the bottom surface of the dust bin <NUM> is horizontal to the ground, the efficiency of collecting the inside of the dust bin <NUM> into the dust storage unit <NUM> by its own weight can be improved.

In the exemplary embodiment of the present specification, an example is described that the separating member <NUM> is maintained in a fixed state. Unlike this, the separating member <NUM> may be moved vertically through a second driving unit (not shown).

The station <NUM> may include a dust storage unit <NUM>. The dust storage unit <NUM> may be disposed in the housing <NUM>. The dust storage unit <NUM> may be disposed under the coupling body <NUM>. Accordingly, when the body cover <NUM> is separated from the dust bin <NUM>, the dust in the dust bin <NUM> may be collected by the dust storage unit <NUM> by gravity.

The station <NUM> may include a first flow path <NUM>. The first flow path <NUM> may connect the dust bin <NUM> of the first cleaner <NUM> and the dust storage unit <NUM>.

For example, when only the first cleaner <NUM> is coupled on the station <NUM>, the valve <NUM> may connect the first flow path <NUM> and the dust storage unit <NUM>, and separate the second flow path <NUM> and the dust storage unit <NUM>.

As another example, when only the second first cleaner <NUM> is coupled on the station <NUM>, the valve <NUM> may separate the connection between the first flow path <NUM> and the dust storage unit <NUM>, and connect the second flow path <NUM> and the dust storage unit <NUM>.

As another example, when both the first cleaner <NUM> and the second cleaner <NUM> are coupled on the station <NUM>, the valve <NUM> may connect the first flow path <NUM> and the dust storage unit <NUM> and separate the second flow path <NUM> and the dust storage unit <NUM>, thereby removing the dust in the dust bin <NUM> from the first cleaner <NUM>. Thereafter, the valve <NUM> may separate the connection between the first flow path <NUM> and the dust storage unit <NUM> and connect the second flow path <NUM> and the dust storage unit <NUM>, thereby removing the dust from the second cleaner <NUM>. Accordingly, the user convenience of the manually operated first cleaner <NUM> can be increased.

The upper surface of the handle <NUM> may form a partial appearance of the upper surface of the first cleaner <NUM>. Thus, when a user grips the handle <NUM>, it is possible to prevent one component of the first cleaner <NUM> from contacting the user's arm.

The first cleaner <NUM> may include an extension part <NUM>. The extension part <NUM> may extend from the handle <NUM> toward the suction motor <NUM>. At least a portion of the extension part <NUM> may extend in a horizontal direction.

The movement limiting part <NUM> may be disposed on one side of the handle <NUM> facing the main body <NUM>. The movement limiting part <NUM> may serve to prevent the user's hand from moving in the longitudinal direction or the vertical direction of the handle <NUM>. The movement limiting part <NUM> may be spaced apart from the extension part <NUM>. That is, while holding the handle <NUM>, some fingers of the user may be located above the movement limiting part <NUM>, and the other fingers may be located below the movement limiting part <NUM>. For example, the movement limiting part <NUM> may be positioned between the index finger and the middle finger.

The battery housing <NUM> may include a heat exhaustion hole (not shown) for discharging the heat generated from the battery <NUM> to an outside. Since heat is discharged to the outside of the battery housing <NUM> by the heat exhaustion hole, the life of the battery <NUM> may be extended through smooth cooling of the battery <NUM>. The battery housing <NUM> may include a receiving part that is opened downward. The battery <NUM> may be received in the receiving part of the battery housing <NUM>.

The first cleaner <NUM> may include an extension tube <NUM>. The extension tube <NUM> may be in communication with the cleaning module <NUM>.

The first cleaner <NUM> may include a battery <NUM>. The battery <NUM> may be detachably coupled to the first cleaner <NUM>. The battery <NUM> may be detachably coupled to the battery housing <NUM>. For example, the battery <NUM> may be inserted into the battery housing <NUM> from below the battery housing <NUM>. The battery <NUM> may supply power to the suction motor <NUM> of the first cleaner <NUM>.

The battery <NUM> may be disposed under the handle <NUM>. The battery <NUM> may be disposed behind the dust bin <NUM>. That is, the suction motor <NUM> and the battery <NUM> may be arranged so as not to overlap in the vertical direction, and the arrangement height may be different. Based on the handle <NUM>, a suction motor <NUM> having a heavy weight is disposed in front of the handle <NUM>, and a battery <NUM> having a heavy weight is disposed below the handle <NUM>, so that the overall weight can be evenly distributed through the first cleaner <NUM>. Thus, when a user holds the handle <NUM> and cleans, it is possible to prevent the user's wrist from being strained.

When the battery <NUM> is coupled to the battery housing <NUM>, the lower surface of the battery <NUM> may be exposed to an outside. When the first cleaner <NUM> is placed on a floor, the battery <NUM> may be placed on the floor, so that the battery <NUM> can be directly separated from the battery housing <NUM>. In addition, since the lower surface of the battery <NUM> is exposed to the outside and directly contacts the external air of the battery <NUM>, the cooling performance of the battery <NUM> may be improved.

The main body <NUM> may include a body cover <NUM>. The body cover <NUM> may be disposed under the lower part of the dust bin <NUM>. The body cover <NUM> may selectively open and close the lower part of the dust bin <NUM> that is opened downward. The body cover <NUM> may rotate downward based on a hinge part <NUM>.

The main body <NUM> may include a compression unit <NUM>. The compression unit <NUM> may be disposed in the dust bin <NUM>. The compression unit <NUM> may move the inner space of the dust bin <NUM>. Specifically, the compression unit <NUM> may move up and down in the dust bin <NUM>. Thus, the compression unit <NUM> may compress the dust in the dust bin <NUM> downward. In addition, when the body cover <NUM> is separated from the dust bin <NUM> and the lower part of the dust bin <NUM> is opened, the compression unit <NUM> moves from the upper part to the lower part of the dust bin <NUM> to remove the foreign matter such as the residual dust in the dust bin <NUM>. Thus, the suction power of the cleaner may be improved by preventing residual dust from remaining in the dust bin. In addition, it is possible to remove odors generated by the residue by preventing the residual dust from remaining in the dust bin.

The main body <NUM> may include a second control unit <NUM>. The second control unit <NUM> may protrude outside the body <NUM>. The second control unit <NUM> may be disposed outside the dust bin <NUM> or the dust separator <NUM>. The second control unit <NUM> may be disposed to move up and down outside the dust bin <NUM> or the dust separator <NUM>. The second control unit <NUM> may be connected to the compression unit <NUM>. When the second control unit <NUM> moves downward by the user's external force, the compression unit <NUM> may also move downward. Accordingly, user convenience can be provided. The compression unit <NUM> and the second control unit <NUM> may be returned to their original positions by an elastic member (not shown). Specifically, when the external force applied to the second control unit <NUM> is removed, the elastic member may move the second control unit <NUM> and the compression unit <NUM> upward.

The dust removal system <NUM> may include a second cleaner <NUM>. The second cleaner <NUM> may include a robot cleaner.

The second cleaner <NUM> may include a distance sensor that senses a distance to an obstacle such as furniture, office supplies, or walls installed in a cleaning area, and a left wheel and a right wheel for moving the robot cleaner.

The second cleaner <NUM> may be coupled to the station so that the dust storage space in the second cleaner <NUM> may be connected to the second flow path <NUM> of the station <NUM> in a flow path.

The dust in the second cleaner <NUM> may be collected into the dust storage unit <NUM> through the second flow path <NUM>.

Referring to <FIG> and <FIG>, when a user approaches the station <NUM>, the first door member <NUM> may move upward, and the coupling body <NUM> may be exposed upward. In this case, whether the user approaches the station <NUM> may be detected through the first sensing unit <NUM>. Thus, since the user does not need to open and close the first door member <NUM> separately, user convenience can be provided.

Referring to <FIG> and <FIG>, when a user mounts the first cleaner <NUM> on the coupling body <NUM> of the station <NUM>, the main body <NUM> of the first cleaner <NUM> may be stably disposed on the coupling body <NUM> by the slope of the coupling surface <NUM> and the first to third guide parts <NUM>, <NUM> and <NUM>. Thus, it is convenient that the main body <NUM> of the first cleaner <NUM> is coupled on the coupling surface <NUM>.

Referring to <FIG> and <FIG>, when the main body <NUM> of the first cleaner <NUM> is disposed on the coupling body <NUM>, the fixing part <NUM> can make the main body <NUM> of the first cleaner <NUM> to move. Specifically, when the second sensing unit <NUM> detects that the main body <NUM> of the first cleaner <NUM> is coupled on the coupling body <NUM> of the station <NUM>, the fifth driving unit <NUM> moves a fixing member <NUM> upward and fixes the main body <NUM> of the first cleaner <NUM>.

Accordingly, the amount of vibration and impact generated when the body cover <NUM> of the main body <NUM> of the fixed first cleaner <NUM> is separated from the dust bin <NUM> is increased, and the efficiency of moving the dust stored in the dust bin <NUM> to the dust storage unit <NUM> of the station <NUM> may be improved. That is, the suction power of the cleaner may be improved by preventing residual dust from remaining in the dust bin. In addition, it is possible to remove odors generated by the residue by preventing residual dust from remaining in the dust bin.

In the exemplary embodiment of the present specification, the fifth driving unit <NUM> is described as an example of a solenoid actuator, but is not limited thereto and may be variously changed to an electromagnetic force actuator.

Referring to <FIG>, when the main body <NUM> of the first cleaner <NUM> is fixed to the coupling body <NUM>, the second driving unit <NUM> moves the separating member <NUM> downward so that the body cover <NUM> can be separated from the dust bin <NUM>. When the body cover <NUM> is separated from the dust bin <NUM>, the dust in the dust bin <NUM> may be collected by the dust storage unit <NUM> by gravity and load. At this time, the opening and closing member <NUM> rotates downward by the weight of the dust bin <NUM> separated from the dust bin <NUM>, so that the lower part of the dust bin <NUM> and the dust storage unit <NUM> may communicate with each other. Alternatively, in the exemplary embodiment of the present specification, it may be implemented except for the opening and closing member <NUM>.

Accordingly, since the dust in the dust bin can be removed without a separate manipulation of a user, user convenience can be provided. In addition, it is possible to eliminate the hassle of the user having to empty the dust bin every time. In addition, when the dust bin is emptied, it is possible to prevent the dust from scattering.

Referring to <FIG> and <FIG>, when the main body <NUM> of the first cleaner <NUM> is fixed to the coupling body <NUM>, the first driving unit (not shown) may rotate the coupling surface <NUM>. In this case, since the coupling surface <NUM> is positioned horizontally with a ground, it is possible to improve the efficiency in which the dust inside the dust bin <NUM> is collected by its own weight into the dust storage unit <NUM>.

Even when the coupling surface <NUM> rotates, the body cover <NUM> may be separated from the dust bin <NUM> by the second driving unit <NUM> as shown in <FIG>. In contrast, when a separate protrusion is formed on the inner surface of the coupling body and the coupling surface <NUM> is horizontal with the ground, the protrusion formed on the inner surface of the coupling body contacts the coupling lever <NUM> to separate the body cover <NUM> from the dust bin <NUM>.

Hereinafter, in <FIG>, a state in which the coupling body <NUM> is in a predetermined state with the ground will be described as an example, but it can be understood that the coupling body <NUM> may be in a state horizontal with the ground as shown in <FIG>.

Referring to <FIG>, the dust storage unit <NUM> may include a roll vinyl <NUM>. The roll vinyl <NUM> is fixed to the housing <NUM> and can be spread down by the load of the dust falling from the dust bin <NUM>.

The joint parts <NUM>,<NUM> may include a first joint member <NUM> and a second joint member <NUM>. The first joint member <NUM> may move in a first direction through a sixth driving unit (not shown), and the second joint member <NUM> may move in a second direction perpendicular to the first direction through a seventh driving unit (not shown).

Referring to <FIG>, when the control unit <NUM> moves downward, the compression unit <NUM> may move downward to move the dust in the dust bin <NUM> downward. In one embodiment of the present specification, the body cover <NUM> is separated from the dust bin <NUM> and the dust in the dust bin <NUM> is primarily collected by the dust separator <NUM> by gravity, and then, the residual dust in the dust bin <NUM> may be secondly collected by the dust separator <NUM> by the compression unit <NUM>. In contrast, the compression unit <NUM> compresses the dust in the dust bin <NUM> downward while the body cover <NUM> is coupled to the dust bin <NUM>, and the body cover <NUM> is separated from the dust bin <NUM> and the dust in the dust bin <NUM> may be collected by the dust separator <NUM>.

Referring to <FIG>, the station <NUM> according to another embodiment of the present specification may include a first flowing part <NUM>. The first flowing part <NUM> may flow air to the suction unit <NUM> of the first cleaner <NUM>. The air flowing to the suction unit <NUM> of the first cleaner <NUM> may move the remaining dust in the dust bin <NUM> downward and collect it into the dust storage unit <NUM>. Accordingly, the suction power of the first cleaner <NUM> may be improved by preventing the residual dust from remaining in the dust bin <NUM>. In addition, by preventing residual dust from remaining in the dust bin <NUM>, the odors generated by the residue may be removed.

Referring to <FIG>, the station <NUM> according to another embodiment of the present specification may include a sealing member <NUM> that seals the suction unit <NUM> of the main body <NUM> of the first cleaner <NUM> coupled on the coupling body <NUM>, and an inspirator <NUM> that sucks the dust from the dust bin <NUM> and collects the dust into the dust storage unit <NUM>. Accordingly, the suction power of the first cleaner <NUM> may be improved by preventing the residual dust from remaining in the dust bin <NUM>. In addition, by preventing the residual dust from remaining in the dust bin <NUM>, the odors generated by the residue may be removed.

Referring to <FIG>, the station <NUM> according to another embodiment of the present specification may include a sealing member <NUM> that seals the suction unit <NUM> of the main body <NUM> of the first cleaner <NUM> coupled on the coupling body <NUM>, and a second flowing part <NUM> for flowing air into the dust bin <NUM>. The second flowing part <NUM> may be understood to be the same as the first flowing part <NUM>. The second flowing part <NUM> may flow the air into the dust bin <NUM> instead of the suction unit <NUM>. The air flowing into the dust bin <NUM> of the first cleaner <NUM> may move the remaining dust in the dust bin <NUM> downward and collect it into the dust storage unit <NUM>. Accordingly, the suction power of the first cleaner <NUM> may be improved by preventing residual dust from remaining in the dust bin <NUM>. In addition, by preventing the residual dust from remaining in the dust bin <NUM>, the odors generated by the residue may be removed.

The second flowing part <NUM> may include a discharge part <NUM> for discharging air and a fourth driving unit (not shown) that rotates the discharge part <NUM> with respect to the first axis <NUM>. Since the discharge part <NUM> rotates about the first axis <NUM> and flows air to various areas of the dust bin <NUM>, the residual dust in the dust bin <NUM> can be efficiently removed.

Referring to <FIG> and <FIG>, the station <NUM> according to another exemplary embodiment of the present specification may include removal parts that moves to the inside of the dust bin <NUM> and removes the remaining dust inside the dust bin <NUM>.

Referring to <FIG>, the removal parts may include a second removal member <NUM>. The second removal member <NUM> may move from the top to the bottom of the dust bin <NUM> and scrape off the residual dust in the dust bin <NUM>.

Accordingly, the suction power of the first cleaner <NUM> may be improved by preventing residual dust from remaining in the dust bin <NUM>. In addition, by preventing residual dust from remaining in the dust bin <NUM>, the odors generated by the residue may be removed.

Referring to <FIG> and <FIG>, the station <NUM> according to one embodiment of the present specification may include a holder <NUM>. The holder <NUM> may extend in the vertical direction.

In the exemplary embodiment of the present specification, the supporting part <NUM> is described as being formed on the side of the housing <NUM>, but the present disclosure is not limited thereto, and the supporting part <NUM> may be disposed on the upper surface of the housing <NUM>. In addition, in one embodiment of the present specification, the supporting part <NUM> is described as an example that is formed in a hexahedral shape extending in the vertical direction, but the shape of the supporting part <NUM> can be variously changed if it can support the main part <NUM>.

The holder <NUM> may include a locking part <NUM>. The locking part <NUM> may be disposed on the upper part of the main part <NUM>. The locking part <NUM> may be coupled with the first cleaner <NUM> to stably fix the first cleaner <NUM>. The locking part <NUM> may include a plurality of locking members spaced apart in a horizontal direction. The main body <NUM> of the first cleaner <NUM> may be fitted in a space between the plurality of locking members from above. In this case, the inner surface of the locking part <NUM> may be slidably coupled to the outer surface of the main body <NUM> of the first cleaner <NUM>. A sliding groove may be formed on an inner surface of the locking part <NUM>, and a sliding protrusion that is slidably coupled to the sliding groove of the locking part <NUM> may be formed on an outer surface of the main body <NUM> of the first cleaner <NUM>. Alternatively, a sliding protrusion may be formed on the inner surface of the locking part <NUM>, and a sliding groove may be formed on the outer surface of the main body <NUM> of the first cleaner <NUM>.

An extra cleaning module <NUM> may be disposed on the holder <NUM>. The extra cleaning module <NUM> may be detachably coupled to the holder <NUM>. In general, the first cleaner <NUM> may variously include replaceable cleaning modules <NUM>, <NUM>, and <NUM> according to usage.

The extra cleaning modules <NUM> and <NUM> may be referred to as 'accessories'.

Referring to <FIG>, the coupling body <NUM> of the station <NUM> according to one embodiment of the present specification may be separated.
