On the other hand, the suction duct 3, the housing portion 20, the slide member 30 and the guide member 50 is configured in a tubular shape having a different diameter.

According to the above, the suction duct 3 and the guide member 50 are configured to have different diameters, but after forming the end bin 23 on one side of the housing portion 20, the guide By preventing the gap from being formed by connecting and fixing one end of the member 50, the air containing dust and foreign matter can be smoothly flown and can be configured to reduce the friction noise of the air by the gap.

Next, the operation and effect of the caster device of the remote control cleaner according to the present invention configured as described above will be described.

First, when power is applied to the cleaner body 1, the suction motor 8 is driven to generate a strong suction force, and thus dust and foreign substances scattered on the floor surface of the room are sucked together with the air.

In addition, the air containing the dust and foreign matter mixed into the suction port (2) is introduced into the dust collection pack (5) in the dust collecting chamber (6) through the suction duct (3).

On the other hand, when the cleaning of the predetermined portion is finished, the user of the cleaner is selectively rotated by the left and right wheels 10, 12 by the operation of the operation lever 40 of the remote controller (not shown) and its own program, thereby moving the cleaner to the next cleaning portion.

That is, since the slide member 30 is connected to the housing portion 20 so as to be movable up and down, it is possible to clean a flexible bottom portion such as a carpet having a large friction resistance with respect to the slide member 30 and a rigid bottom portion of concrete or sheet metal. In this case, the height of the slide member 30 and the sole member 40 is changed in preparation for the frictional resistance between the slide member 30 and the sole member 40 on the suction port 2 side and the bottom of the surface to be cleaned. In the soluble bottom, such as the sole member 40 flows elastically to reduce the frictional resistance due to the change of the material of the bottom portion and acts as above in the rigid floor of concrete or lamellae.

That is, in the flexible floor, such as carpet and the rigid floor of concrete or sheet metal, the slide member 30 is elastically flow by the elastic force of the elastic member to reduce the frictional resistance to increase the running of the cleaner Will be.

At this time, the slide member 30 is prevented from being separated from the suction duct 3 by the locking projection 31 and the locking jaw 21, the locking projection 31 of the slide member 30 is the housing portion 20 The upward movement is limited by contacting the end of the.

In addition, when the slide member 30 passes over the protrusion 33 such as a threshold, the impact force applied to the slide member 30 by the elastic force of the elastic member may be reduced to prevent breakage of the slide member 30. Will be.

As described above, according to the suction device of the omni-directional mobile cleaner according to the present invention, the height of the inlet and outlet portion of the suction duct easily and elastically varies the height of the suction port irrespective of the material of the bottom to effectively inhale dust and foreign matter. It is possible to improve the cleaning efficiency by making it more efficient, and at the same time, when the protrusions are raised, the impact is reduced to prevent breakage of the suction duct.
