Description

[Detailed description of the invention] This invention is an electric vacuum cleaner that aims to hygienically dispose of the fine dust collected inside the vacuum cleaner body without getting your hands dirty, and to improve the dust removal effect by improving the pre-filter. This relates to a dust treatment device for a machine.

To dispose of fine dust collected in a conventional vacuum cleaner, remove the dust collection box attached to the main body of the vacuum cleaner, then remove the pre-filter inside this box and remove the dust accumulated between the pre-filter and the main filter into the box. It was a better way to get rid of it.

Therefore, when disposing of fine dust, the filters were touched with hands, resulting in dirt and unsanitary conditions.

The present invention has been devised to eliminate the above-mentioned drawbacks and will be explained in detail below with reference to an embodiment shown in the drawings.

Reference numeral 1 denotes a vacuum cleaner main body with a built-in electric blower 2, a concave housing portion 4 having an end face with an intake port 3 provided at the front portion, and an exhaust port 5 formed at the rear portion.

Reference numeral 6 is a dust collection box having a handle 7 and openings on both front and rear surfaces, and is detachably attached to the storage section 4 from the upper surface side of the cleaner body 1.

Reference numeral 8 denotes a ""-shaped pre-filter for collecting bulky debris, which consists of a vertical part 8a and a horizontal part 8b, and is installed at the rear of the inside of the dust collection box 6, with a gap 10 provided at the rear of the vertical part 8a. A main filter 9 for collecting fine dust is arranged.

Further, a passage 11 for guiding fine dust is provided between the horizontal part 8b of the pre-filter 8 and the bottom of the dust collection box 6, and the rear part of the passage 11 is connected to the vertical part 8a and the main filter 9. The front end of the dust collecting box 6 communicates with the gap 10 formed between the dust collecting boxes 6 and 6, and opens at the front of the dust collecting box 6.

Reference numeral 12 denotes an opening/closing lid for disposing of garbage, which has an inlet 13 opposite to the inlet 3, and is the front face of the dust collection box 6 (including the front end of the passage 9).

) can be opened and closed, and the upper end has a handle 7 with a hinge 14.
The front end of the horizontal portion 8b of the pre-filter 8 comes into contact with the back surface of the pre-filter 8.

In the embodiment described above, when the electric blower 2 is driven to suck air containing dust from the intake port 3, the air containing dust enters the dust collection box 6 from the intake port 13, where it enters the vertical part of the pre-filter 8. Large dust particles are collected by the filter 8a and the horizontal portion 8b, and the remaining small dust particles pass through the pre-filter 8 and are collected by the main filter 9.

Then, only the purified air passes through the electric blower 2 and is discharged from the exhaust port 5.

The above-mentioned pre-filter 8 has a shape that allows air to pass through both the vertical part 8a and the horizontal part 8b, so the intake area is about twice that of the conventional one, and clogging occurs accordingly. It becomes difficult.

By the way, to dispose of the dust collected in this way, first apply mechanical vibration to the main filter 9 to remove small dust, then lift the dust collection box 6 by the handle 7 and remove it from the storage part 4, and leave it as it is in a specified place. Then, you can open the opening/closing lid 12 and throw away the dust between the lid 12 and the prefilter 8.

Of course, the dust accumulated in this part is large, so simply turn the front side of the dust collection box 6 down to open the dust collection box 6.
can be thrown away from the front.

On the other hand, fine dust that has fallen into the gap 10 between the prefilter 8 and the main filter 11 can be thrown away together with the large dust through a passage 11 provided between the prefilter 8 and the dust collection box 6.

As described above, according to the structure of the present invention, by removing the dust collection box from the storage part of the vacuum cleaner body, carrying this dust collection box to a predetermined place, and opening the opening/closing lid, not only dust but also fine dust can be removed at once. It can be disposed of, and the dust inside is not scattered when touching the filter or removing and carrying the dust collection box, making it hygienic and easy to dispose of dust, making it practical. This is a similarly useful idea.
