Abstract

A cleaner includes a body which forms an outer appearance; a mop module having at least one rag part which is provided to wipe a floor while rotating; and a detaching module comprising at least one catching portion which detachably catches the mop module to the body, and a manipulation button which is exposed outside, wherein when the manipulation portion is touched, the catching portion releases catching of the mop module.

First claim

What is claimed is:

1. A cleaner comprising:
a body;
a mop module having at least one mopping surface which is positioned to clean a floor while rotating; and
a detaching module that includes:
at least one catching extension which detachably couples the mop module from the body, and
a manipulation surface which is exposed outside of the cleaner,

wherein:
the at least one catching extension is positioned to release the mop module when the manipulation surface is touched by a user,
the mop module comprises body mounting protrusions which protrude upward from the mop module and are spaced apart from each other,
the body comprises module mounting recesses which are recessed upward in the body to receive the body mounting protrusions,
the module mounting recesses include catching surfaces which are each inserted between the body mounting protrusions,
the at least one catching extension includes a plurality of catching extensions, and
the plurality of catching extensions protrude from the catching surfaces.

2. The cleaner of claim 1 , wherein the mop module is connected to a bottom of the body,
the manipulation surface is exposed at the bottom of the body, and
the catching extension is configured to release the mop module when the manipulation surface is pressed upward.

3. The cleaner of claim 2 , wherein the manipulation surface is spaced apart from the mop module in a forward-and-backward direction.

4. The cleaner of claim 1 , wherein:
the at least one catching extension includes a pair of catching extensions,
the detaching module comprises a pair of catching plates coupled, respectively, to the pair of catching extensions, and
each of the pair of catching plates is movable in a corresponding catching release direction opposite to a protruding direction of each of the catching extensions.

5. The cleaner of claim 4 , wherein:
the detaching module further includes a moving assembly which is movable in a given moving direction, and
the moving assembly and the pair of catching plates are connected with each other, so that when the moving assembly moves in the moving direction, each of the catching plates moves, respectively, in the corresponding catching release direction.

6. The cleaner of claim 1 , wherein the catching extension releases the mop module when the manipulation surface is moved in a predetermined pressing direction.

7. The cleaner of claim 1 , wherein the detaching module includes:
a catching plate which includes a catching portion and is movable in a predetermined catching release direction; and
a leading member which is connected with the catching plate and moves the catching portion when the leading member is moved.

8. The cleaner of claim 7 , wherein the detaching module further includes a spring which is elastically deformed when the catching plate moves in the catching release direction and provides an elastic force in a direction opposite to the catching release direction.

9. The cleaner of claim 7 , wherein:
the leading member includes a moving assembly which is movable in a predetermined moving direction, and
the moving assembly and the catching plate are connected with each other, so that the catching portion moves in the catching release direction when the moving assembly moves in the moving direction.

10. The cleaner of claim 9 , wherein the catching release direction is different from the moving direction.

11. The cleaner of claim 9 , wherein one of the catching plate or the moving assembly has a groove or a hole which is extended in an inclination direction between a direction opposite to the moving direction and the catching release direction, and another one of the catching plate or the moving assembly has a protrusion which is inserted into the groove or the hole to move along the groove or the hole.

12. The cleaner of claim 9 , wherein the leading member further includes a pressing button which includes the manipulation surface, and is movable in a given pressing direction,
wherein the pressing button and the moving assembly are connected with each other, so that the moving assembly moves in the moving direction when the pressing button moves in the pressing direction.

13. The cleaner of claim 12 , wherein the pressing direction is different from the moving direction.

14. The cleaner of claim 12 , wherein one of the pressing button or the moving assembly includes an inclined surface which has a slope between a direction opposite to the moving direction and the pressing direction, and another one of the pressing button or the moving assembly includes a contact end which slides while contacting the inclined surface when the pressing button moves in the pressing direction.

15. The cleaner of claim 14 , wherein one of the pressing button or the moving assembly further includes an insertion surface that protrudes from an end of the inclined surface and contacts one side of the contact end in a catching state in which the pressing button moves a maximum distance in a direction opposite to the pressing direction.

16. The cleaner of claim 12 , wherein the moving assembly includes:
a catching master wall which is connected with the catching plate;
a moving slave wall which is connected with the pressing button; and
an intermediate extension plate which extends to connect the catching master wall and the moving slave wall.

17. The cleaner of claim 12 , wherein the moving assembly is configured to move forward and rearward, and the pressing button is configured to move upward and downward.

18. The cleaner of claim 1 , wherein the at least one catching extension is a first catching extension which is provided to be movable with respect to the body, and the cleaner further comprises a second catching extension which is fixed to the body and catches the mop module to the body along with the first catching extension.

19. The cleaner of claim 1 , wherein the at least one mopping surface is tilted with respect to the floor and rotating the at least one mopping surface causes the cleaner to move.

20. A cleaner comprising:
a body;
a mop module having at least one mopping surface which is positioned to clean a floor while rotating; and
a detaching module that includes:
at least one catching extension which detachably couples the mop module from the body, and
a manipulation surface which is exposed outside of the cleaner,

wherein the at least one catching extension is positioned to release the mop module when the manipulation surface is touched by a user,
wherein the detaching module includes:
a catching plate which includes a catching portion and is movable in a predetermined catching release direction; and
a leading member which is connected with the catching plate and moves the catching portion when the leading member is moved,

wherein the leading member includes a moving assembly which is movable in a predetermined moving direction,
wherein the moving assembly and the catching plate are connected with each other, so that the catching portion moves in the catching release direction when the moving assembly moves in the moving direction,
wherein the leading member further includes a pressing button which includes the manipulation surface, and is movable in a given pressing direction,
wherein the pressing button and the moving assembly are connected with each other, so that the moving assembly moves in the moving direction when the pressing button moves in the pressing direction, and
wherein the moving assembly includes:
a catching master wall whi
