Title: Station and dust removal system including the same

Description:
TECHNICAL FIELD 
     The present disclosure relates to a docking station and a dust removal system including the same, and more particularly, to a docking station for collecting the dust stored in a cleaning apparatus and a dust removal system including the same. 
     BACKGROUND 
     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 canister vacuum cleaners, uplight cleaners, hand vacuum cleaners, and stick vacuum cleaners depending on the shape of the cleaners. 
     Traditionally canister 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 canister 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&#39;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&#39;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.

     Still further, the present disclosure provides a station and a dust removal system having the same, capable of preventing residue dust from remaining in a dust bin and removing odors generated by the residue. 
     Means to Solve the Problem 
     The station according to one aspect of the present specification may be a station to which a cleaner including a dust bin and a body cover selectively opening and closing a lower part of the dust bin is coupled, including a coupling body to which the dust bin is coupled and forms a predetermined angle with a ground; a separating unit which separates the body cover from the dust bin; and a dust storage unit which is disposed under the coupling body. 
     In this case, when the body cover is separated from the dust bin, the dust in the dust bin may be collected by gravity into the dust storage unit. 
     Through this, 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 dust from scattering. 
     In this case, the predetermined angle may be between 20 degrees and 30 degrees, and the dust bin may be slid by gravity and coupled to the coupling body. 
     Through this, since the dust bin can always be placed in a correct position, user convenience can be improved. 
     In this case, a lower surface of the dust bin may be formed of a polycarbonate (PM) plastic material, an upper surface of the coupling body may be formed of a polyoxymethylene (POM) plastic material, and the predetermined angle may be between 23 degrees and 30 degrees. 
     In addition, the station may include a sensing unit which detects whether the dust bin is coupled to the coupling body; and a first driving unit which drives the separating unit when the dust bin is coupled to the coupling body. 
     In addition, the coupling body may include a coupling surface which forms the predetermined angle with the ground and to which a lower surface of the dust bin is coupled, and a first guide part which is connected to the coupling surface and formed in a shape corresponding to an outer surface of the dust bin. 
     In addition, the station may include a sensing unit which detects whether the dust bin is coupled to the coupling body; and a fixing part which fixes the cleaner when the dust bin is coupled to the coupling body. 
     In addition, the fixing part may include a fixing member which is disposed on both sides of a bottom surface of the cleaner, and a second driving unit which moves the fixing member up and down. The second driving unit may move the fixing member upward when the dust bin is coupled to the coupling body. 
     In addition, the coupling body may include a coupling surface to which a lower surface of the dust bin is coupled, and a second guide part which is protruded upward from the coupling surface and corresponds to a width of the cleaner. The fixing member may be disposed on the second guide part, and a width of the fixing member may be formed to be smaller than a width of the second guide part. 
     Through this, since the cleaner coupled to the coupling body may be fixed, the dust in the dust bin may be collected into the dust storage unit due to the impact of opening the body cover. 
     In addition, the separating unit may separate a coupling lever which couples the body cover to the dust bin from the dust bin to selectively open and close the lower part of the dust bin. 
     In this case, the station may include a sensing unit which detects whether the dust bin is coupled to the coupling body, and the separating unit may include a separating member which is disposed on an upper part of the coupling lever, and a first driving unit which moves the separating member downward when the dust bin is coupled to the coupling body. 
     In addition, the coupling body may include a coupling surface to which a lower surface of the dust bin is coupled, and an opening and closing member which is disposed under the body cover and selectively opens and closes at least a part of the coupling surface. When the body cover is separated from the dust bin, the opening and closing member may rotate to one side by a weight of the body cover to communicate the dust bin and the dust storage unit. 
     In this case, the station may include a second driving unit which rotates the opening and closing member to other side when the dust in the dust bin is removed. When the opening and closing member is rotated to the other side, the body cover may be coupled to the dust bin by the opening and closing member. 
     The station according to one aspect of the present specification may be a station to which a cleaner including a dust bin and a body cover selectively opening and closing a lower part of the dust bin is coupled, including a coupling body to which the dust bin is coupled and forms a predetermined angle with a ground; a separating unit which separates the body cover from the dust bin; a dust storage unit which is disposed under the coupling body; a sensing unit which detects whether the dust bin is coupled to the coupling body; and a fixing part which fixes the cleaner when the dust bin is coupled to the coupling body. The dust bin may be slid by gravity and coupled to the coupling body. 
     In this case, when the body cover is separated from the dust bin, the dust in the dust bin may be collected by gravity into the dust storage unit. 
     Through this, 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 dust from scattering. 
     In this case, the fixing part may include a fixing member which is disposed on both sides of a bottom surface of the cleaner, and a second driving unit which moves the fixing member up and down. When the dust bin is coupled to the coupling body, the second driving unit may move the fixing member upward. 
     In addition, the coupling body may include a coupling surface to which a lower surface of the dust bin is coupled, and a second guide part which is protruded upward from the coupling surface and corresponds to a width of the cleaner. The fixing member may be disposed on the second guide part, and a width of the fixing member may be formed to be smaller than a width of the second guide part. 
     Through this, since the cleaner coupled to the coupling body may be fixed, the dust in the dust bin may be collected into the dust storage unit due to the impact of opening the body cover. 
     In this case, a lower surface of the dust bin may be formed of a polycarbonate (PM) plastic material, an upper surface of the coupling body may be formed of a polyoxymethylene (POM) plastic material, and the predetermined angle may be between 23 degrees and 30 degrees. 
     Through this, since the dust bin can always be placed in a correct position, user convenience can be improved. 
     In addition, the coupling body may include a coupling surface which forms the predetermined angle with the ground and to which the lower surface of the dust bin is coupled, and a first guide part which is connected to the coupling surface and is formed in a shape corresponding to an outer surface of the dust bin. 
     In addition, the separating unit may include a separating member which is disposed an upper part of a coupling lever coupling the body cover to the dust bin, and a first driving unit which moves the separating member downward when the dust bin is coupled to the coupling body. 
     In addition, the coupling body may include a coupling surface to which a lower surface of the dust bin is coupled, and an opening and closing member which is disposed under the body cover and selectively opens and closes at least a part of the coupling surface. When the body cover is separated from the dust bin, the opening and closing member may rotate to one side by a weight of the body cover to communicate the dust bin and the dust storage unit. 
     In addition, the station may include a second driving unit which rotates the opening and closing member to other side when dust in the dust bin is removed. When the opening and closing member is rotated to the other side, the body cover may be coupled to the dust bin by the opening and closing member. 
     The dust removal system according to one aspect of the present specification may include a cleaner including a suction unit, a suction motor which generates a suction force that sucks air along the suction unit, a dust separator which separates dust from air introduced through the suction unit, a dust bin which stores the dust separated from the dust separator, a body cover which selectively opens and closes a lower part of the dust bin, and a compression unit which moves an inner space of the dust bin and compresses the dust in the dust bin downward; and a station including a coupling body to which the dust bin is coupled, a separating unit which separates the body cover from the dust bin, and a dust storage unit which is disposed under the coupling body. The coupling body may form a predetermined angle with a ground, and the dust bin may be slid by gravity and coupled to the coupling body. 
     Through this, since it is possible to remove the dust in the dust bin by always placing the dust bin in a correct position without user&#39;s separate manipulation, 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 dust from scattering.

     Reference to  FIGS.  1  to  29   , the dust removal system  10  according to one embodiment of the present disclosure may include a station  100 , a first cleaner  200 , and a second cleaner  300 . However, in one embodiment of the present disclosure, some of these components may be excluded or additional components may be included, 
     The dust removal system  10  may include a station  100 . The first cleaner  200  and the second cleaner  300  may be disposed to the station  100 . The first cleaner  200  may be coupled on the upper part of the station  100 . Particularly, on the upper part of the station  100 , the main body of the first cleaner  200  may be coupled. The second cleaner  300  may be coupled under the lower part of the station. The station  100  may remove the dust of the dust bin  215  of the first cleaner  200 . The station  100  may remove the dust of the dust bin (unshown) of the second cleaner  300 . 
     The station  100  may include a housing  110 . The housing  110  can form the exterior appearance of the station  100 . A coupling body  120  on which the first cleaner  200  is coupled may be disposed on the upper part of the housing  110 . The second cleaner  300  may be coupled under the lower part of the housing  110 . A dust storage unit  130 , a first flow path  140 , a second flow path  150 , a valve  160  and an inspirator  170  may be disposed inside the housing  110 . In one embodiment of the present disclosure, the housing  110  is descried as being formed in a hexahedron shape as an example, but the shape of the housing  110  is not limited thereto, and the shape of the housing  110  may be variously changed. 
     The housing  110  may include a first door member  112 . The first door member  112  may be disposed on the upper surface of the housing  110 . The first door member  112  may selectively expose to an outside the coupling body  120  disposed on the upper part of the housing  100 . The first door member  112  may be opened when a user approaches the station  100 , and the first door member  112  may be closed when the first cleaner  200  coupled on the station  100  is separated from the station  100 . Accordingly, it is possible to prevent foreign matters such as dust from entering inside of the station  100 . 
     The housing  110  may include a first sensing unit  113 . The first sensing unit  113  may be disposed on the housing  110 . The first sensing unit  113  may detect whether a user approaches the station  100 . The first sensing unit  113  may include a non-contact sensor. As one exemplary, the first sensing unit  113  may include an infrared sensing unit (IR sensor). The first sensing unit  113  may include a contact sensor. As one exemplary, the first sensing unit  113  may include a micro switch. In one embodiment of the present disclosure, the first sensing unit  113  is disposed on the upper surface of the housing as one example. However, the position of the first sensing unit  113  may be variously changed as long as it can detect whether a user approaches or not. 
     The station  100  may include the coupling body  120 . The coupling body  120  may be disposed on the upper part of the station  100 . The coupling body  120  may be disposed on the upper part of the housing  110 . The coupling body  120  may be selectively opened and closed by the first door member  112 . The first cleaner  200  may be coupled on the coupling body  120 . The main body  210  of the first cleaner  200  may be coupled on the coupling body  120 . 
     The coupling body  120  may form a predetermined angle with a ground. Through this, when a user couples the main body  210  of the first cleaner  200  to the station  100 , the main body  210  of the first cleaner  200  may be slid and coupled to the coupling body  120  in a correct position. 
     In one embodiment of the present specification, the predetermined angle of the coupling body  120  formed with the ground may be between 20 degrees and 30 degrees. 
     If the predetermined angle of the coupling body  120  formed with the ground is greater than 30 degrees, the inclination of the dust bin  215  is severe and there is a risk that the dust in the dust bin  215  remains due to gravity. 
     In addition, if the predetermined angle of the coupling body  120  formed with the ground is less than 20 degrees, the dust bin  215  may not slide the coupling body  120  because it does not reach the static friction force between the lower surface of the dust bin  215  and the upper surface of the coupling body  120 . 
     In one embodiment of the present specification, the lower surface of the dust bin  215  may be formed of a polycarbonate (PM) plastic material, and the upper surface of the coupling body  120  may be formed of a polyoxymethylene (POM) plastic material. In this case, the coefficient of static friction of the polycarbonate plastic material with respect to the polyoxymethylene plastic material may be about 0.22. In addition, when a correction of 1.5 times is applied due to a foreign matter between the lower surface of the dust bin  215  and the upper surface of the coupling body  120 , tanθ may be about 0.33. That is, if the predetermined angle of the coupling body  120  formed with the ground is less than 20 degrees, the dust bin  215  may not slide the coupling body  120  because it does not reach the static friction force between the lower surface of the dust bin  215  and the upper surface of the coupling body  120 . 
     Preferably, the predetermined angle of the coupling body  120  formed with the ground may be between 23 degrees and 30 degrees. Considering the weight of the main body  210  of the first cleaner  200  and the average female body condition, if the predetermined angle of the coupling body  120  formed with the ground is less than 23 degrees, the user&#39;s wrist may be strained. 
     The coupling body  120  may include a coupling surface  121 . The coupling surface  121  may be disposed on the upper surface of the housing  110 . The first cleaner  200  may be coupled on the coupling surface  121 . Specifically, the main body  210  of the first cleaner  200  may be coupled on the coupling surface  121 . For example, the dust bin  215  of the first cleaner  200  may be disposed on the coupling surface  121 . The coupling surface  121  may form a predetermined angle with a ground. For example, an angle formed by the coupling surface  121  with the ground may be an acute angle. Accordingly, it is convenient that the main body  210  of the first cleaner  200  is coupled on the coupling surface  121 . Here, the coupling between the coupling surface  121  and the main body  210  of the first cleaner  200  may mean a physical coupling in which the first cleaner  200  and the station  100  are coupled and fixed. 
     The coupling body  120  may include a first guide part  122 . The first guide part  122  may be disposed on the upper part of the housing  110 . The first guide part  122  may be connected to the upper surface of the housing  110 . The first guide part  122  may be connected to the coupling surface  121 . The first guide part  122  may form a predetermined angle with the ground. For example, an angle formed by the first guide part  122  with the ground may be an obtuse angle. The first guide part  122  may be formed in a shape corresponding to the outer surface of the dust bin  215 . The outer surface of the dust bin  215  may be coupled on the first guide part  122 . Accordingly, there is convenience that the main body  210  of the first cleaner  200  is coupled on the coupling surface  121 . 
     The coupling body  120  may include a second guide part  123 . The second guide part  123  may be disposed on the coupling surface  121 . The second guide part  123  may protrude upward from the coupling surface  121 . The second guide part  123  may include first and second guide members spaced apart from each other. The distance between the first guide member and the second guide member may correspond to the width of the main body  210  of the first cleaner  200 . Specifically, the distance between the first guide member and the second guide member may correspond to the width of the battery housing  220  of the first cleaner  200 . Accordingly, there is convenience that the main body  210  of the first cleaner  200  is coupled on the coupling surface  121 . 
     The coupling body  120  may include a fixing part  124 . The fixing part  124  may be disposed on the coupling surface  121 .

In an embodiment of the present invention, the fifth driving unit  1291  is described as an example of moving the fixing member  129  up and down, but as long as the main body  210  of the first cleaner  200  is fixed to the coupling body  120 , the shape of the fixing member  129  and the type of the fifth driving unit  1291  may be variously changed. 
     For example, when the dust bin  215  is coupled to the coupling body  120 , the fifth driving unit  1291  moves the fixing member  129  upward to fix the main body  210  of the first cleaner  200  to the coupling body  120 . 
     The fixing member  129  may be disposed on both sides of the bottom surface of the main body  210  of the first cleaner  200  coupled to the coupling body  120 . The width of the fixing member  129  may correspond to the width of the main body  210  of the first cleaner  200  or may be smaller than the width of the main body  210  of the first cleaner  200 . The fixing member  129  may be disposed on the second guide part  123 . Specifically, referring to  FIGS.  4 ,  7 ,  9  and  10   , the fixing member  129  may be disposed on a surface of the first and second guide members facing each other. Through this, the main body  210  of the first cleaner  200  guided by the second guide part  123  may be fixed in a correct position. 
     In an embodiment of the present invention, the fifth driving unit  1291  is described as an example of moving the fixing member  129  up and down, but as long as the main body  210  of the first cleaner  200  is fixed to the coupling body  120 , the shape of the fixing member  129  and the type of the fifth driving unit  1291  may be variously changed. 
     The coupling body  120  may include a second sensing unit  125 . The second sensing unit  125  may be disposed in the housing  110 . The second sensing unit  125  may detect whether the first cleaner  200  is coupled on the coupling body  120 . The second sensing unit  125  may face the main body  210  of the first cleaner  200 . The second sensing unit  125  may include a non-contact sensor. For example, the second sensing unit  125  may include an infrared sensor unit (IR sensor). The second sensing unit  125  may include a contact sensor. For example, the second sensing unit  125  may include a micro switch. 
     The coupling body  120  may include an opening and closing member  126 . The opening and closing member  126  may be disposed in the housing  110 . The opening and closing member  126  may be disposed on the coupling surface  121 . The opening and closing member  126  may selectively open and close at least a part of the coupling surface  121  to communicate the upper part of the coupling body  120  with a first flow path  140  and/or the dust storage unit  130 . The opening and closing member  126  may be opened when the body cover  240  of the first cleaner  200  is opened. The opening and closing member  126  may rotate downward based on a second axis  1261 . The opening and closing member  126  may be closed by a connection member  191  and a third driving unit  190 . For example, the opening and closing member  126  may be rotated to one side by the third driving unit  190 . The opening and closing member  126  may close the body cover  240  of the first cleaner  200  by closing the opening and closing member  126 . Through this, the dust bin  215  of the first cleaner  200  and the first flow path  140  may be coupled in a flow path so that a fluid flows. 
     The coupling body  120  may include a first driving unit (not shown). The first driving unit may be disposed in the housing  110 . The first driving unit may rotate the coupling surface  121 . When the dust bin  215  is coupled on the coupling surface  121 , the first driving unit may rotate the coupling surface  121  horizontally with a ground. Accordingly, it is possible to improve the collecting efficiency that the dust inside the dust bin  215  is collected by its own weight into the dust storage unit  130 . 
     The coupling body  120  may include a third guide part  127 . The third guide part  127  may be disposed on the upper part of the housing  110 .

The shape of the third guide part  127  may be formed in a shape corresponding to the shape of the suction unit  214 . Accordingly, there is convenience that the main body  210  of the first cleaner  200  is coupled on the coupling surface  121 . 
     The station  100  may include a separating unit  128 . The separating unit  128  may be disposed on the coupling surface  121 . The separating unit  128  may be disposed adjacent to the second guide part  122 . When the main body  210  of the first cleaner  200  is coupled on the coupling body  120 , the separating unit  128  may separate the body cover  240  from the dust bin  215 . The separating unit  128  may include a separating member  111  and a second driving part  1111  driving the separating member  111 . The separating member  111  may be disposed on an upper part of the main body  210  of the first cleaner  200 . Specifically, the separating member  111  may be disposed on an upper part of the coupling lever  241  of the first cleaner  200 . The second driving unit  1111  may drive the separating member  111  when the dust bin  215  is coupled on the coupling body  120 . Specifically, when the second driving unit  1111  moves the separating member  111  downward, the separating member  111  separates the coupling lever  241  from the dust bin  215  to selectively open and close the lower part of the dust bin  215 . In this case, the dust in the dust bin  215  may move downward and be collected by the dust storage unit  130  due to the impact occurred by the separation of the body cover  240  from the dust bin  215 . 
     The station  100  may include a dust storage unit  130 . The dust storage unit  130  may be disposed in the housing  110 . The dust storage unit  130  may be disposed under the coupling body  120 . Accordingly, when the body cover  240  is separated from the dust bin  215 , the dust in the dust bin  215  may be collected by the dust storage unit  130  by gravity. 
     The station  100  may include a first flow path  140 . The first flow path  140  may connect the dust bin  215  of the first cleaner  200  and the dust storage unit  130 . The first flow path  140  may refer to a space between the dust bin  215  of the first cleaner  200  and the dust storage unit  130 . Unlike  FIG.  2   , the first flow path  140  may mean a straight area extending vertically. The dust in the dust bin  215  of the first cleaner  200  may move to the dust storage unit  130  through the first flow path  140 . 
     The station  100  may include a second flow path  150 . The second flow path  150  may connect the second cleaner  300  and the dust storage unit  130 . The dust in the second cleaner  300  may move to the dust storage unit  130  through the second flow path  150 . 
     The station  100  may include a valve  160 . The valve  160  may be disposed between the dust storage unit  130 , the first flow path  140  and the second flow path  150 . The valve  160  may selectively open and close the first flow path  140  and the second flow path  150  connected to the dust storage unit  130 . Accordingly, it is possible to prevent the decrease in suction power caused by opening the plurality of flow paths  140  and  150 . 
     For example, when only the first cleaner  200  is coupled on the station  100 , the valve  160  may connect the first flow path  140  and the dust storage unit  130 , and separate the second flow path  150  and the dust storage unit  130 . 
     As another example, when only the second first cleaner  300  is coupled on the station  100 , the valve  160  may separate the connection between the first flow path  140  and the dust storage unit  130 , and connect the second flow path  150  and the dust storage unit  130 . 
     As another example, when both the first cleaner  200  and the second cleaner  300  are coupled on the station  100 , the valve  160  may connect the first flow path  140  and the dust storage unit  130  and separate the second flow path  150  and the dust storage unit  130 , thereby removing the dust in the dust bin  215  from the first cleaner  200 . Thereafter, the valve  160  may separate the connection between the first flow path  140  and the dust storage unit  130  and connect the second flow path  150  and the dust storage unit  130 , thereby removing the dust from the second cleaner  300 . Accordingly, the user convenience of the manually operated first cleaner  200  can be increased. 
     The station  100  may include an inspirator  170 . The inspirator  170  may be disposed in the dust storage unit  130 . Alternatively, the inspirator  170  may be disposed outside the dust storage unit  130  and may be connected to the dust storage unit  130 . The inspirator  170  may generate suction power in the first flow path  140  and the second flow path  150 . Accordingly, the inspirator  170  may provide a suction power capable of sucking the dust in the dust bin  215  of the first cleaner  200  and the dust in the second cleaner  300 . 
     The station  100  may include a charging unit (not shown). The charging unit may include a first charger (not shown) disposed on the coupling body  120 . The first charger may be electrically connected to the first cleaner  200  coupling on the coupling body  120 . The first charger may supply power to the battery of the first cleaner  200  coupled on the coupling body  120 . In addition, the charging unit may include a second charger (not shown) disposed on the lower region of the housing  110 .

     The station  100  may include a side door (not shown). The side door may be disposed on the housing  110 . The side door may selectively expose the dust storage unit  130  to an outside. Thus, since a user can use the dust storage unit  130  as a trash bin, user convenience can be improved. In addition, it allows a user to easily remove the dust storage unit  130  from the station  100 . 
     The dust removal system  10  may include a first cleaner  200 . The first cleaner  200  may include a cleaner manually operated by a user. For example, the first cleaner  200  may be a hand vacuum cleaner or a stick vacuum cleaner.

The dust in the dust bin  215  of the first cleaner  200  may be collected by gravity into the dust storage unit  130  of the station  100 . Accordingly, since the dust in the dust bin can be removed without a separate manipulation of the 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.

External dust may flow into the main body  210  through the cleaning module  290  and the extension tube  280 . 
     A hinge  282  may be disposed on the extension tube  280 . Specifically, at least a portion of the extension tube  280  may be rotated based on the hinge  282 . Accordingly, when the main body  210  of the first cleaner  200  is coupled to the station  100 , the extension tube  280  may support the main body  210 . 
     The main body  210  may include a suction unit  214 . The suction unit  214  may protrude outward from the main body  210 .

The flow guide may guide the flow of air discharged through the air discharge outlet  212 . 
     The first cleaner  200  may include a handle  216 . The handle  216  can be held by a user. The handle  216  may be disposed behind the suction motor  205 . That is, the shaft of the suction motor  205  may be disposed between the suction unit  214  and the handle  216 . In the exemplary embodiment of the present specification, a front refers to a direction in which the suction unit  214  is disposed relative to the suction motor  205 , and a rear may refer to a direction in which the handle  216  is disposed. The upper surface of the handle  216  may form a partial appearance of the upper surface of the first cleaner  200 . Thus, when a user grips the handle  216 , it is possible to prevent one component of the first cleaner  200  from contacting the user&#39;s arm. 
     The first cleaner  200  may include an extension part  218 . The extension part  218  may extend from the handle  216  toward the suction motor  205 . At least a portion of the extension part  218  may extend in a horizontal direction.

     The first cleaner  200  may include a battery housing  220 . The battery  230  may be accommodated in the battery housing  220 . The battery housing  220  may be disposed under the handle  216 . The battery housing  220  may have a hexahedral shape with an open lower part. The rear surface of the battery housing  220  may be connected to the handle  216 . 
     The battery housing  220  may include a heat exhaustion hole (not shown) for discharging the heat generated from the battery  230  to an outside. Since heat is discharged to the outside of the battery housing  220  by the heat exhaustion hole, the life of the battery  230  may be extended through smooth cooling of the battery  230 . The battery housing  220  may include a receiving part that is opened downward. The battery  230  may be received in the receiving part of the battery housing  220 .

External air may flow into the main body  210  of the first cleaner  200  through the cleaning module  290  and the extension tube  280  due to the suction power generated by the main body  210  of the first cleaner  200 . 
     The first cleaner  200  may include a battery  230 . The battery  230  may be detachably coupled to the first cleaner  200 . The battery  230  may be detachably coupled to the battery housing  220 . For example, the battery  230  may be inserted into the battery housing  220  from below the battery housing  220 . The battery  230  may supply power to the suction motor  205  of the first cleaner  200 . 
     The battery  230  may be disposed under the handle  216 . The battery  230  may be disposed behind the dust bin  215 .

Based on the handle  216 , a suction motor  205  having a heavy weight is disposed in front of the handle  216 , and a battery  230  having a heavy weight is disposed below the handle  216 , so that the overall weight can be evenly distributed through the first cleaner  200 . Thus, when a user holds the handle  216  and cleans, it is possible to prevent the user&#39;s wrist from being strained. 
     When the battery  230  is coupled to the battery housing  220 , the lower surface of the battery  230  may be exposed to an outside. When the first cleaner  200  is placed on a floor, the battery  230  may be placed on the floor, so that the battery  230  can be directly separated from the battery housing  220 . In addition, since the lower surface of the battery  230  is exposed to the outside and directly contacts the external air of the battery  230 , the cooling performance of the battery  230  may be improved. 
     The main body  210  may include a body cover  240 . The body cover  240  may be disposed under the lower part of the dust bin  215 . The body cover  240  may selectively open and close the lower part of the dust bin  215  that is opened downward. The body cover  240  may rotate downward based on a hinge part  242 .

The compression unit  250  may move the inner space of the dust bin  215 . Specifically, the compression unit  250  may move up and down in the dust bin  215 . Thus, the compression unit  250  may compress the dust in the dust bin  215  downward. In addition, when the body cover  240  is separated from the dust bin  215  and the lower part of the dust bin  215  is opened, the compression unit  250  moves from the upper part to the lower part of the dust bin  215  to remove the foreign matter such as the residual dust in the dust bin  215 . 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  210  may include a second control unit  251 . The second control unit  251  may protrude outside the body  210 . The second control unit  251  may be disposed outside the dust bin  215  or the dust separator  211 . The second control unit  251  may be disposed to move up and down outside the dust bin  215  or the dust separator  211 . The second control unit  251  may be connected to the compression unit  250 . When the second control unit  251  moves downward by the user&#39;s external force, the compression unit  250  may also move downward. Accordingly, user convenience can be provided. The compression unit  250  and the second control unit  251  may be returned to their original positions by an elastic member (not shown). Specifically, when the external force applied to the second control unit  251  is removed, the elastic member may move the second control unit  251  and the compression unit  250  upward. 
     The dust removal system  10  may include a second cleaner  300 . The second cleaner  300  may include a robot cleaner. The second cleaner  300  may automatically clean the area to be cleaned by inhaling foreign matters such as dust from a floor while driving the area to be cleaned by itself. The second cleaner  300  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  300  may be coupled to the station so that the dust storage space in the second cleaner  300  may be connected to the second flow path  150  of the station  100  in a flow path. 
     The dust in the second cleaner  300  may be collected into the dust storage unit  130  through the second flow path  150 . 
     Referring to  FIGS.  3  and  4   , when a user approaches the station  100 , the first door member  112  may move upward, and the coupling body  120  may be exposed upward. In this case, whether the user approaches the station  100  may be detected through the first sensing unit  113 . Thus, since the user does not need to open and close the first door member  112  separately, user convenience can be provided. 
     Referring to  FIGS.  5  and  6   , when a user mounts the first cleaner  200  on the coupling body  120  of the station  100 , the main body  210  of the first cleaner  200  may be stably disposed on the coupling body  120  by the slope of the coupling surface  121  and the first to third guide parts  122 ,  123  and  127 . Thus, it is convenient that the main body  210  of the first cleaner  200  is coupled on the coupling surface  121 . 
     Referring to  FIGS.  8  and  10   , when the main body  210  of the first cleaner  200  is disposed on the coupling body  120 , the fixing part  124  can make the main body  210  of the first cleaner  200  to move. Specifically, when the second sensing unit  125  detects that the main body  210  of the first cleaner  200  is coupled on the coupling body  120  of the station  100 , the fifth driving unit  1291  moves a fixing member  129  upward and fixes the main body  210  of the first cleaner  200 . 
     Accordingly, the amount of vibration and impact generated when the body cover  240  of the main body  210  of the fixed first cleaner  200  is separated from the dust bin  215  is increased, and the efficiency of moving the dust stored in the dust bin  215  to the dust storage unit  130  of the station  100  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  1291  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.  11   , when the main body  210  of the first cleaner  200  is fixed to the coupling body  120 , the second driving unit  1111  moves the separating member  111  downward so that the body cover  240  can be separated from the dust bin  215 . When the body cover  240  is separated from the dust bin  215 , the dust in the dust bin  215  may be collected by the dust storage unit  130  by gravity and load. At this time, the opening and closing member  126  rotates downward by the weight of the dust bin  215  separated from the dust bin  215 , so that the lower part of the dust bin  215  and the dust storage unit  130  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  126 . 
     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. 
     In the exemplary embodiment of the present specification, the second driving unit  1111  is described as an example of a solenoid actuator, but the present disclosure is not limited thereto and may be variously changed to an electromagnetic force actuator. 
     Referring to  FIGS.  12  and  13   , when the main body  210  of the first cleaner  200  is fixed to the coupling body  120 , the first driving unit (not shown) may rotate the coupling surface  121 . In this case, since the coupling surface  121  is positioned horizontally with a ground, it is possible to improve the efficiency in which the dust inside the dust bin  215  is collected by its own weight into the dust storage unit  130 . 
     Even when the coupling surface  121  rotates, the body cover  240  may be separated from the dust bin  215  by the second driving unit  1111  as shown in  FIG.  11   . In contrast, when a separate protrusion is formed on the inner surface of the coupling body and the coupling surface  121  is horizontal with the ground, the protrusion formed on the inner surface of the coupling body contacts the coupling lever  241  to separate the body cover  240  from the dust bin  215 . 
     Referring to  FIG.  14   , the dust storage unit  130  may include a roll vinyl  132 . The roll vinyl  132  is fixed to the housing  110  and can be spread down by the load of the dust falling from the dust bin  215 . 
     Referring to  FIGS.  24  and  25   , the station  100  may include joint parts. The joint parts may be disposed on the housing  110 . The joint parts may be disposed on the upper area of the dust storage unit  130 . The joint parts may cut and joint the upper area of the roll vinyl  132  in which dust is collected. Specifically, the joint parts may collect the roll vinyl  132  into a central region and bonds the upper region of the roll vinyl  132  with heat-wire. The joint parts may include a first joint member  134  and a second joint member  135 . The first joint member  134  may move in a first direction through a sixth driving unit (not shown), and the second joint member  135  may move in a second direction perpendicular to the first direction through a seventh driving unit (not shown). 
     Referring to  FIGS.  15  and  16   , when the control unit  251  moves downward, the compression unit  250  may move downward to move the dust in the dust bin  215  downward. In one embodiment of the present specification, the body cover  240  is separated from the dust bin  215  and the dust in the dust bin  215  is primarily collected by the dust separator  130  by gravity, and then, the residual dust in the dust bin  215  may be secondly collected by the dust separator  211  by the compression unit  250 . In contrast, the compression unit  250  compresses the dust in the dust bin  215  downward while the body cover  240  is coupled to the dust bin  215 , and the body cover  240  is separated from the dust bin  215  and the dust in the dust bin  215  may be collected by the dust separator  130 . 
     Referring to  FIG.  17   , the station  100  according to another embodiment of the present specification may include a first flowing part  172 . The first flowing part  172  may flow air to the suction unit  214  of the first cleaner  200 . The air flowing to the suction unit  214  of the first cleaner  200  may move the remaining dust in the dust bin  215  downward and collect it into the dust storage unit  130 . Accordingly, the suction power of the first cleaner  200  may be improved by preventing the residual dust from remaining in the dust bin  215 . In addition, by preventing residual dust from remaining in the dust bin  215 , the odors generated by the residue may be removed. 
     Referring to  FIG.  18   , the station  100  according to another embodiment of the present specification may include a sealing member  2142  that seals the suction unit  214  of the main body  210  of the first cleaner  200  coupled on the coupling body  120 , and an inspirator  174  that sucks the dust from the dust bin  215  and collects the dust into the dust storage unit  130 . Accordingly, the suction power of the first cleaner  200  may be improved by preventing the residual dust from remaining in the dust bin  215 . In addition, by preventing the residual dust from remaining in the dust bin  215 , the odors generated by the residue may be removed. 
     Referring to  FIG.  19   , the station  100  according to another embodiment of the present specification may include a sealing member  2142  that seals the suction unit  214  of the main body  210  of the first cleaner  200  coupled on the coupling body  120 , and a second flowing part  176  for flowing air into the dust bin  215 . The second flowing part  176  may be understood to be the same as the first flowing part  172 . The second flowing part  176  may flow the air into the dust bin  215  instead of the suction unit  214 . The air flowing into the dust bin  215  of the first cleaner  200  may move the remaining dust in the dust bin  215  downward and collect it into the dust storage unit  130 . Accordingly, the suction power of the first cleaner  200  may be improved by preventing residual dust from remaining in the dust bin  215 . In addition, by preventing the residual dust from remaining in the dust bin  215 , the odors generated by the residue may be removed. 
     The second flowing part  176  may include a discharge part  1762  for discharging air and a fourth driving unit (not shown) that rotates the discharge part  1762  with respect to the first axis  1761 . Since the discharge part  1762  rotates about the first axis  1761  and flows air to various areas of the dust bin  215 , the residual dust in the dust bin  215  can be efficiently removed. 
     Referring to  FIGS.  20  and  21   , the station  100  according to another exemplary embodiment of the present specification may include removal parts that moves to the inside of the dust bin  215  and removes the remaining dust inside the dust bin  215 . 
     Referring to  FIG.  20   , the removal parts may include a first removal member  177 . The first removal member  177  may rotate based on the central area of the dust bin  215  and scrape off the residual dust in the dust bin  215 . 
     Referring to  FIG.  21   , the removal parts may include a second removal member  178 . The second removal member  178  may move from the top to the bottom of the dust bin  215  and scrape off the residual dust in the dust bin  215 . 
     Accordingly, the suction power of the first cleaner  200  may be improved by preventing residual dust from remaining in the dust bin  215 . In addition, by preventing residual dust from remaining in the dust bin  215 , the odors generated by the residue may be removed. 
     Referring to  FIGS.  22  and  23   , when the dust in the dust bin  215  of the first cleaner  200  is removed, the third driving unit  190  may rotate the opening and closing member  126  to move the body cover  240  into the dust bin  215 . Specifically, the third driving unit  190  may rotate the opening and closing member  126  based on the second axis  1261  by rotating the connection member  191 , and the opening and closing member rotating about the second axis  1261  may push the body cover  240  upward. In this case, the body cover  240  may be rotated based on the hinge part  242  and the coupling lever  241  may be coupled to the dust bin  215 . 
     Referring to  FIGS.  26  and  27   , the station  100  according to one embodiment of the present specification may include a holder  400 . The holder  400  may extend in the vertical direction. The holder  400  may be detachably coupled to the housing  110 . Alternatively, the holder  400  may be integrally formed with the housing  110 . The first cleaner  200  may be held by the holder  400 . The holder  400  may support the first cleaner  200 . 
     The holder  400  may include a main part  410 . The main part  410  may be disposed on the supporting part  420 . The main part  410  may be disposed on the supporting part  420 .

     The holder  400  may include a supporting art  420 . The supporting part  420  may be detachably coupled to the housing  110 . Alternatively, the supporting part  420  may be integrally formed with the housing  110 . The supporting part  420  may support the main part  410 . In the exemplary embodiment of the present specification, the supporting part  420  is described as being formed on the side of the housing  110 , but the present disclosure is not limited thereto, and the supporting part  420  may be disposed on the upper surface of the housing  110 . In addition, in one embodiment of the present specification, the supporting part  420  is described as an example that is formed in a hexahedral shape extending in the vertical direction, but the shape of the supporting part  420  can be variously changed if it can support the main part  410 . 
     The holder  400  may include a locking part  430 . The locking part  430  may be disposed on the upper part of the main part  410 . The locking part  430  may be coupled with the first cleaner  200  to stably fix the first cleaner  200 . The locking part  430  may include a plurality of locking members spaced apart in a horizontal direction. The main body  210  of the first cleaner  200  may be fitted in a space between the plurality of locking members from above. In this case, the inner surface of the locking part  430  may be slidably coupled to the outer surface of the main body  210  of the first cleaner  200 . A sliding groove may be formed on an inner surface of the locking part  430 , and a sliding protrusion that is slidably coupled to the sliding groove of the locking part  430  may be formed on an outer surface of the main body  210  of the first cleaner  200 . Alternatively, a sliding protrusion may be formed on the inner surface of the locking part  430 , and a sliding groove may be formed on the outer surface of the main body  210  of the first cleaner  200 . 
     An extra cleaning module  500  may be disposed on the holder  400 . The extra cleaning module  500  may be detachably coupled to the holder  400 . In general, the first cleaner  200  may variously include replaceable cleaning modules  290 ,  510 , and  520  according to usage. Accordingly, the unused extra cleaning modules  510  and  520  may be stored in a state coupled to the holder  400  to reduce the risk of loss. The extra cleaning modules  510  and  520  may be referred to as ‘accessories’. 
     Referring to  FIG.  28   , the coupling body  120  of the station  100  according to one embodiment of the present specification may be separated. Specifically, the coupling body  120  and the first door member  112  of the station  100  may be detachably coupled to the housing  110 . When the coupling body  120  is removed, the dust storage unit  130  disposed in the housing  110  may be exposed upward, and a user may use the station  100  as a general trash. In addition, when the dust storage unit  130  is filled with dust, the user can easily remove and/or replace the dust storage unit  130 , thereby providing user convenience.
