In particular, the present invention relates to a self-standing structure of a vacuum cleaner in which a directly connected suction port body is placed in an upright state in which it comes into contact with a floor surface.

[0002]

2. Description of the Related Art Conventionally, there is a general vacuum cleaner having a structure as shown in FIG. 10 which is called a self-standing type. This kind of vacuum cleaner 31 sucks external air. It has a cleaner main body 34 in which an electric blower 32 and a dust collecting chamber 33 for collecting dust in the sucked external air are provided. Then, one end side of the cleaner body 34 (in the figure,
A suction port 35, which is directly connected to the dust collection chamber 33 and is rotatably and swingably supported, is connected to the lower end (the lower end), and is connected to the other end (the upper end in the drawing). Is connected to a rod-shaped operation handle body 36. As shown in FIG. 10, the vacuum cleaner 31 is not in an upright state in which the bottom surface of the suction port body 35 contacts the floor surface G to be cleaned.

It is necessary to increase the bottom area of 5 and to improve the stability. However, when the bottom area of the suction port body 35 is increased, the suction port body 35 inevitably increases in size. As a result, when the vacuum cleaner 31 is placed, that is, when the vacuum cleaner 31 is not used. Although the stability is increased, the operability during use (during cleaning) is inferior.

If the width of the suction body 35 exceeds the width of the cleaner body 34 as a result of the increase in the bottom area of the suction body 35, the space between the furniture and the wall or the furniture may be reduced. Since the suction port body 35 does not enter between them, there is a problem that sufficient cleaning cannot be performed. In addition, in the conventional vacuum cleaner 31, cleaning is performed after the back surface of the cleaner body 34 is laid down so as to face the floor surface G. In such a case, the operation is performed. The handle body 36 and the handle support 37 may come into contact with and damage the floor surface G.

The present invention has been made in view of these disadvantages, and has as its object to provide a vacuum cleaner having a structure capable of improving operability while ensuring stability when not in use. I have.
