Abstract

The present disclosure relates to a cleaner. Since the cleaner includes: a pitch member configured to rotate the main body about the pitch axis; a yaw member configured to rotate the main body about the yaw axis; and a roll member configured to rotate the main body about the roll axis, and limits a rotation of the roll member when the main body is in a first location, and allows a rotation of the roll member when the main body is in a second location, the cleaner secures excellent operability when the cleaner is in the first location which is higher, and excellent straightness when the cleaner is in the second location which is lower.

First claim

What is claimed is:

1 . A cleaner, comprising:
a cleaning module for sucking in an outside air; a main body for providing a suction force to the cleaning module; a pitch member disposed between the cleaning module and the main body, having a pitch axis disposed in left and right directions, and configured to rotate the main body about the pitch axis; a yaw member disposed between the cleaning module and the main body, having a yaw axis disposed in left and right directions, and configured to rotate the main body about the yaw axis; a roll member disposed between the cleaning module and the main body, having a roll axis disposed in left and right directions, and configured to rotate the main body about the roll axis; and an anti-roll assembly disposed in the roll member and configured to limit a rotation of the roll member when the main body is in a first location, and allow a rotation of the roll member when the main body is in a second location.

2 . The cleaner of claim 1 ,
wherein a height of the main body in the first location is higher than a height of the main body in the second location.

3 . The cleaner of claim 1 , further comprising:
an anti-yaw assembly having one end coupled to the yaw member and another end locked by the pitch member.

4 . The cleaner of claim 3 ,
wherein when the main body is in the first location, a force with which the anti-yaw assembly limits a rotation of the yaw member is smaller than a force with which the roll member limits a rotation of the roll member.

5 . The cleaner of claim 3 ,
wherein the anti-yaw assembly comprises: a support member disposed in the pitch member; and a fixing member coupled to the yaw member and having at least a portion thereof locked by the support member.

6 . The cleaner of claim 5 ,
wherein the fixing member comprises: a yaw member coupling part coupled to the yaw member; a fixing member arm extending along an outer circumference of the support member from the yaw member coupling part; and a fixing protrusion extending inward from an end of the fixing member arm and locked by the support member.

7 . The cleaner of claim 3 ,
wherein at least a portion of the fixing member comprises an elastic material.

8 . The cleaner of claim 3 ,
wherein the anti-yaw assembly further comprises: an elastic member providing a restoration force in an opposite direction, when the yaw member rotates in one direction.

9 . The cleaner of claim 1 ,
wherein the anti-roll assembly has one end coupled to the anti-yaw member and another end locked by the roll member.

10 . The cleaner of claim 9 ,
wherein the anti-roll assembly comprises: a support member disposed in the roll member and protruding toward the yaw member; and a fixing member coupled to the yaw member and having at least a portion thereof locked
