DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a general household vacuum cleaner.

[0002]

2. Description of the Related Art A conventional vacuum cleaner is disclosed in
The one disclosed in JP-A-7951 is generally used.
Hereinafter, a description will be given with reference to FIGS. In the figure, reference numeral 1 denotes a dust collecting chamber 6 in which an electric blower 2 and the like are built in a rear part, and a dust collecting bag 5 provided with a mouth frame 4 having an intake hole 3 in a front part.
Reference numeral 7 denotes a lid which covers the dust collection chamber 6 so as to be openable and closable from above. In front of the dust collecting chamber 6, an intake hole 3 is provided.
A groove 9 for supporting the lower end of the dust bag 5 and aligning the position of the suction hole 3 with the suction port 8 is provided on the front bottom surface of the main body. Is provided, and furthermore, it is provided rotatably upward and forward.
A frame holder 10 supporting the substantially center of the frame is provided over a range substantially equivalent to the inner diameter of the frame.

[0003]

However, in the case of having the above-mentioned mouth frame holder 10, since the mouth frame holder 10 is located at the center, when the dust bag 5 is inserted, the dust bag 5 is inserted from above. Since the groove 9 for determining the position of 5 and the intake port 8 are hidden by the frame holder 10 and are difficult to see,
The dust bag 5 was attached by feeling. For this reason, erroneous insertion occurs, and the suction hole 3 and the suction port 8 are displaced. As a result, dust leaks, which causes a failure of the electric blower 2 and a failure of the vacuum cleaner.

When taking out the dust bag 5 filled with dust, the mouth frame retainer 10 is caught in the intake hole 3 and
Not only is it difficult to remove the dust, but the dust in the dust bag 5 may spill, giving the user a sense of mistrust. The dust spilled into the dust collection chamber 6 directly enters the electric blower, thereby causing electricity to flow. This could lead to a vacuum cleaner failure.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and makes it possible to smoothly attach and remove a dust collection bag, and to prevent dust from entering a motor-driven blower due to dust leakage. The purpose is.

The lower part of the main body has a dust collecting chamber 16 for disposing a dust collecting bag 15 provided with a cover 4. Reference numeral 17 denotes a lid that covers the dust collecting chamber 16 so as to be able to open and close from above. In front of the dust collection chamber 16, there is an intake port 18 having substantially the same size as the intake hole 13, and on the lower front surface, a dust bag 15 is attached. And a slot holder 20 that is rotatable forward and upward to hold and fix two places at both ends of the slot 14.

The operation of the above configuration is as follows.
As shown in FIG. 3, by fixing both ends of the mouth frame 14 with the mouth frame holder 20, when the dust bag 15 is mounted, the groove 19 on the bottom surface of the dust collection chamber 16 and the suction port 18 from above. Can be easily visually observed, so that erroneous insertion of the dust collecting bag 15 can be prevented, and a malfunction of the vacuum cleaner due to dust leakage caused by erroneous insertion can be prevented.
