Abstract

A station and a dust removal system including the same are provided. The station according to one aspect of the present specification is 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, the predetermined angle being between 20 degrees and 30 degrees, and the dust bin being slid by gravity and coupled to the coupling body.

First claim

1 . 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, comprising;
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, wherein the predetermined angle is between 20 degrees and 30 degrees, and the dust bin is slid by gravity and is coupled to the coupling body.

2 . The station of claim 1 ,
wherein a lower surface of the dust bin is formed of a polycarbonate (PC) plastic material, an upper surface of the coupling body is formed of a polyoxymethylene (POM) plastic material, and the predetermined angle is between 23 degrees and 30 degrees.

3 . The station of claim 1 , comprising:
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.

4 . The station of claim 1 ,
wherein the coupling body includes 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.

5 . The station of claim 1 , comprising:
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.

6 . The station of claim 5 ,
wherein the fixing part includes 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, and wherein the second driving unit moves the fixing member upward when the dust bin is coupled to the coupling body.

7 . The station of claim 6 ,
wherein the coupling body includes 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 is disposed on the second guide part, and a width of the fixing member is formed to be smaller than a width of the second guide part.

8 . The station of claim 1 ,
wherein the separating unit separates 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.

9 . The station of claim 8 , comprising a sensing unit which detects whether the dust bin is coupled to the coupling body,
wherein the separating unit includes 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.

10 . The station of claim 1 ,
wherein the coupling body includes 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, and wherein when the body cover is separated from the dust bin, the opening and closing member rotates to one side by a weight of the body cover to communicate the dust bin and the dust storage unit.

11 . The station of claim 10 , comprising a second driving unit which rotates the opening and closing member to other side when dust in the dust bin is removed,
wherein when the opening and closing member is rotated to the other side, the body cover is coupled to the dust bin by the opening and closing member.

12 . 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, comprising;
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, wherein the dust bin is slid by gravity and is coupled to the coupling body.

13 . The station of claim 12 ,
wherein the fixing part includes 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, and when the dust bin is coupled to the coupling body, the second driving unit moves the fixing member upward.

14 . The station of claim 13 ,
wherein the coupling body includes 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 is disposed on the second guide part, and a width of the fixing member is formed to be smaller than a width of the second guide part.

15 . The station of claim 12 ,
wherein a lower surface of the dust bin is formed of a polycarbonate (PC) plastic material, an upper surface of the coupling body is formed of a polyoxymethylene (POM) plastic material, and the predetermined angle is between 23 degrees and 30 degrees.

16 . The station of claim 12 ,
wherein the coupling body includes 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.

17 . The station of claim 12 ,
wherein the separating unit includes 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.

18 . The station of claim 12 ,
wherein the coupling body includes 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, and when the body cover is separated from the dust bin, the opening and closing member rotates to one side by a weight of the body cover to communicate the dust bin and the dust storage unit.
