Abstract

A cleaning mechanism, a cleaning device, and an air conditioner are disclosed. The cleaning mechanism is configured to remove dust of an member object to be cleaned, and includes a dust suction member and a switch member. The dust suction member is movable in a reciprocating manner with respect to a surface to be cleaned of the object, and is provided with at least two separate dust suction chambers each having a dust suction port. In an extension direction of the dust suction chambers, a projected length of the dust suction port on the surface to be cleaned is smaller than the length of the surface to be cleaned. Each of the dust suction chambers is configured to communicate with a fan, and the switch member selectively communicates the fan with one of the dust suction chambers.

First claim

The invention claimed is:

1. An air conditioner, comprising a filter screen and a cleaning mechanism for removing dust from the filter screen, wherein the cleaning mechanism comprises:
a fan;
a dust suction member; and
a switch member,
wherein the dust suction member is movable in a reciprocating manner with respect to a surface to be cleaned of the filter screen, and the dust suction member is provided with at least two separate dust suction chambers, each dust suction chamber having a dust suction port respectively; in an extension direction of the dust suction chamber, a projection length of the dust suction port on the surface to be cleaned is smaller than the width of the surface to be cleaned; each of the dust suction chambers is configured to communicate with the fan, and the switch member selectively communicates the fan with one of the dust suction chambers;
wherein the switch member is provided at an outlet of the dust suction chambers between the dust suction chambers and the fan, and the switch member comprises a drive unit and a rotation unit, wherein the rotation unit is provided with a through hole and rotates under a driving action of the drive unit, and a circumferential position of the through hole changes with rotation of the rotation unit to allow the through hole to achieve communication with the outlet of different dust suction chambers, so as to selectively communicate the fan with one of the dust suction chambers.

2. The air conditioner according to claim 1 , wherein the dust suction member is configured as a bracket across the surface to be cleaned, the dust suction chambers are provided in the bracket, and the bracket performs reciprocating movement by cooperation of rollers arranged at two ends of the bracket and slide rails arranged on both sides of the surface to be cleaned.

3. The air conditioner according to claim 1 , wherein the dust suction ports on the dust suction member are arranged in a direction perpendicular to the direction of movement of the dust suction member.

4. The air conditioner according to claim 3 , wherein in the direction perpendicular to the direction of movement of the dust suction member, the dust suction ports overlap each other, so as to fully cover the surface to be cleaned during the movement of the dust suction member.

5. The air conditioner according to claim 1 , wherein a surface of bent portions on an inner wall of the dust suction chambers is configured to be tangent to a flow direction of dust suction air through the bent portions.

6. The air conditioner according to claim 1 , wherein a transition surface at a first connection between the switch member and the outlet of the dust suction chambers is configured to be tangent to a flow direction of dust suction air through the first connection, and a transition surface at a second connection between the switch member and the fan is configured to be tangent to a flow direction of dust suction air through the second connection.

7. The air conditioner according to claim 2 , wherein on a side of the bracket adjacent to the surface to be cleaned is provided with a brush for cleaning dust on the surface to be cleaned.

8. The air conditioner according to claim 1 , further comprising a drive mechanism, the drive mechanism configured to drive the dust suction member to perform reciprocating movement with respect to the surface to be cleaned.

9. The air conditioner according to claim 8 , wherein the drive mechanism comprises a helical gear and a helical rack, and the reciprocating movement of the dust suction member with respect to the surface to be cleaned is caused by engagement of the helical gear and the helical rack.

10. The air conditioner according to claim 1 , wherein the surface to be cleaned comprises a surface of the filter screen arranged on two adjacent surfaces of the air conditioner, and the switch member and a drive mechanism are provided on an intersection between the two adjacent surfaces, so as to clean the surface of said filter screen on at least one of said two adjacent surfaces.
