Abstract
The present invention rotatably installs the travel wheels 51 at both sides of the main body case 25 and below the center of gravity of the cleaner main body 13. The rear wheel 52 is provided so as to be able to advance and retreat to the bottom surface F side behind the rotation shaft 57 of the travel wheel 51 of the main body case 25. The rear wheel 52 is pressurized in the direction which advances toward the bottom surface F, and is made to be able to contact the bottom surface F in an advanced state. Since the rear wheel 52 contacts the bottom surface F at an appropriate contact pressure, the straightness can be improved more than the case where the vehicle travels only the travel wheels 51 without lowering the swingability of the cleaner main body 13.
Description
The present invention relates to an electric vacuum cleaner having travel wheels rotatably provided on both sides of a main body case.
Conventionally, this kind of vacuum cleaner has a main body case, a main body part which is a main body part provided with the electric blower accommodated in this main body case, and the dust collection part arrange | positioned in the main body case in communication with the suction side of this electric blower. On both sides of the main body case, driving wheels for travel are respectively rotatably supported. Moreover, the turning wheel which contact | connects the bottom surface which is the surface to be cleaned at the time of running is arrange | positioned so that the rotation center of the main body case in the substantially center position of the left-right width direction rather than the rotating shaft of the traveling wheel is possible. In addition, the rear wheel which contacts the bottom surface is rotatably arrange | positioned at the substantially center position of the left-right width direction of the rear side rather than the rotation axis of the running wheel of a main body case, when the front side is raised when passing over obstacles, such as a threshold. For example, refer patent document 1).
In the above-mentioned vacuum cleaner, since the turning wheel is always arrange | positioned on the floor surface side with respect to a cleaner body, when a cleaner body turns, a turning wheel becomes a resistance and the swingability of a cleaner body falls.
On the other hand, in the case where only the driving wheels are used without arranging the turning wheels or the like, it is possible to always ensure the swingability of the cleaner main body on the floor, but there is a problem that the straightness is lowered.
This invention is made | formed in view of such a point, and an object of this invention is to provide the vacuum cleaner which can improve a straightness, without reducing the turning property of a main body part.
The present invention is provided on both sides of the main body case and rotatably provided at a position below the center of gravity of the main body, and is provided so as to be able to move forward and backward on the surface to be cleaned on the rear side of the rotation axis of the driving wheel of the main body case. It is provided with the rear wheel pressurized in the advancing direction and contactable with the surface to be cleaned in the advancing state.
According to the present invention, the rear wheel is brought into proper contact with the surface to be cleaned by pressing the rear wheel which is capable of moving back and forth to the surface to be cleaned in the advanced state and which is in contact with the surface to be cleaned in the advanced state. Since it contacts by pressure, straightness can be improved rather than the case where it travels only by a running wheel, without reducing the turning property of a main body part.
