DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an upright type vacuum cleaner.

[0002]

2. Description of the Related Art A conventional upright type vacuum cleaner generally has a configuration as disclosed in Japanese Patent Application Laid-Open No. 64-23829.

That is, when the dust collector is set up and the vacuum cleaner is not used, the main body is prevented from falling down by rotating the handle and bringing a part of the handle into contact with the floor.

[0004]

However, in the above-mentioned conventional structure, there is a problem that the user has to rotate the handle every time, and a mechanism for rotating the handle at the base of the handle is required. Because of this, there were significant restrictions in terms of design.

[0005] In an upright type vacuum cleaner having a detachable hose, the main concern is that the main body may fall down.
This is a case where the hose is detached from the suction portion and an attachment or the like is attached to clean the rear of the main body. In the conventional product, no consideration has been given to this point.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide an upright type vacuum cleaner having high stability and good usability.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a suction unit having an intake port for taking in dust,
A main body having a dust collecting chamber and an electric blower, which is tiltably provided in the suction section, a moving roller, and a hose which communicates the suction section with the dust collection chamber and is detachable from the suction section. And a support portion which can be freely retracted so as to make it difficult for the main body to stand down, so that when the hose is removed from the suction portion, the support portion projects rearward from the rotation center of the moving roller. When the hose is removed from the suction section and the attachment is attached to clean the rear of the body, where the body is most likely to fall down, the support section is automatically removed by removing the hose from the suction section. Projecting to the rear of the transfer roller, the main unit can be prevented from falling backward even if the hose is pulled strongly backward, so that the user does not need to operate the fall prevention mechanism such as the handle every time as in the past, Or , Design the shape, including the handle is also what can be freely.

As another means, a suction unit having an intake port for taking in dust, a main body which is provided in the suction unit so as to be tiltable and has a built-in dust collecting chamber and an electric blower, and a moving roller are provided.
And a handle for operating the main body, and a support portion which is protrudable and retractable to make it difficult for the main body to fall down in an upright state, and a switch provided on the handle or the main body or the suction portion allows the support portion to protrude and retract. It is configured so that it can be selected.By projecting the support part behind the moving roller of the main body by the user's intention, it is possible to prevent the main body from falling backward when using the attachment, etc. Depending on the situation, it is possible to provide diversity by selecting whether or not to protrude the support portion.
