JPH08150101A - Upright type vacuum cleaner - Google Patents

Abstract

PURPOSE: To provide an upright type vacuum cleaner which is inexpensive and can be handled excellently and is of an attachment housing type. CONSTITUTION: The center lines of a hose fitting cylindrical portion and an attachment fitting and main body fitting cylindrical portion constituting a fitting portion do not coincide with each other, and in the state of normal housing, an engage-stopping portion 75 formed at a main body butts against the engage- stopping portion 76 of the fitting portion. Accordingly, a portion against which the fitting portion butts is formed at the main body in a direction in which the fitting portion comes off from the main body naturally, so as long as cleaning is normal, the fitting portion does not come off, no matter what kind of vibration is added, and design is also simple, and in addition, strong fixation is realized due to the pressure insertion of taper fitting, so taking off can be realized simply, and operability and usability are improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an upright type electric vacuum cleaner in which attachments (extension tubes, various nozzles) are stored.

[0002]

2. Description of the Related Art Conventionally, an upright type vacuum cleaner has been constructed as disclosed in Japanese Patent Laid-Open No. 146385/1993.

That is, the removable tip connecting pipe fixed to the tip of the hose provided on the side surface of the main body is inserted into the cylindrical mounting portion provided on the main body of the suction tool and fitted to hold it. It had been.

[0004]

SUMMARY OF THE INVENTION
In the technique described in Japanese Patent Laid-Open No. 5-146385, the tip connecting pipe of the hose is only inserted into the suction tool, and when the fitting of the mounting portion becomes loose due to vibration during cleaning in a normal cleaning state, There was a problem that the tip connecting pipe was pulled out by the elastic force and was disengaged from the suction tool.

Further, in order to prevent the falling-out, the tip connecting pipe is press-fitted and inserted into the suction tool mounting portion by taper fitting, and if firmly fixed, a suction force is also added, and when using the attachment during cleaning, it is troublesome to attach and detach it. There was a problem of poor sex.

It is an object of the present invention to provide an inexpensive and easy-to-handle upright electric vacuum cleaner which is provided with a tip connecting tube which is hard to come off in a normal cleaning state and which is easily detachable.

[0007]

In order to achieve the above object, a main body provided with a dust collecting chamber, a suction tool rotatably coupled at a lower end of the main body, and a back surface of the main body, It has a hose that is a path connecting the suction part of the suction tool and the dust collection chamber of the main body, an extension pipe detachably attached to the main body, and replacement nozzles, and is closer to the suction tool of the hose. In an upright electric vacuum cleaner in which the suction tool is detachably attached to the end of one hose, the center line of the hose mounting cylindrical portion that constitutes the mounting portion and the attachment and main body mounting cylindrical portion are aligned. Instead, the locking portion provided on the main body is configured to come into contact with the locking portion of the mounting portion in a normal storage state.

[0008]

According to the present invention, since the main body is provided with the portion where the mounting portion abuts in the direction in which the mounting portion naturally comes out of the main body, the mounting portion can be removed by any vibration during normal cleaning. The design is simple.

Further, since it is not firmly fixed by the press-fitting insertion, it can be easily removed and the operability and usability are improved.
