Description

[Detailed description of the invention] This invention allows the collected garbage to be easily and hygienically disposed of by accumulating and storing the collected garbage in a garbage storage bag, and then taking out the garbage storage bag and disposing of it together with the stored garbage. This relates to a vacuum cleaner that is capable of processing

Hereinafter, the present invention will be described in detail according to an illustrated embodiment.

FIG. 1 is a schematic sectional view of an embodiment of the present invention, FIG. 2 is a front view of a filter case of the present invention, and FIG. 3 is a side view of the filter case.

First, in Fig. 1, 1 is the main body of the vacuum cleaner.The main body 1 has an external appearance composed of a main body front case 2 and a main body rear case 3.The main body front case 2 and the main body rear case 3 are used for installation. Each is provided so that it can be divided by an engaging metal fitting (not shown), a latch (not shown), or the like.

Reference numeral 4 denotes a handle provided on the upper part of the front case 2 of the main body to make it portable.

Reference numeral 5 indicates wheels for moving the main body 1 of the vacuum cleaner at the bottom of each of the front case 2 and the rear case 3. Reference numeral 6 indicates a suction port assembly (not shown) connected to these wheels. This is a suction port that sucks air through a mouth assembly, and this suction port 6 is provided in a part of the main body front case 2.

7 is a cylindrical main filter, which has a chevron-shaped cross section.

This main filter 7 is surrounded by a cylindrical pre-filter 8 and is provided on the front surface of a filter case 9 within the main body front case 2.

This filter case 9 has a handle portion 10 that allows the filter device to be carried.

A rotatable filter shaft 11 is pivotally installed inside the main filter 7, and the tip of the shaft 11 is fixed to the prefilter 8, and the filter shaft 11 and the prefilter 8 are rotated from the outside of the filter case 9. A dust removal handle 12 that can be operated freely
is mounted on one end.

This dust removal handle 12 has a knob 12 at its tip.
I am wearing A.

Reference numeral 13 denotes a flexible, non-breathable garbage storage bag provided to accumulate and store garbage. It is provided so as to cover the outer periphery of the shaped protrusion 9A, and is fixed by a bag attachment frame 14 from above.

Note that the protrusion 9 provided on this filter case 9
As shown in FIG. 3, A is tilted by changing the height, that is, the amount of protrusion.

The bag attachment frame 14 is detachably attached, and the garbage storage bag 13 can be attached or removed depending on the attachment/detachment state of the bag attachment frame 14.

Of course, it goes without saying that the garbage storage bag 13 is attached at the opening side.

The filter case 9 is detachably attached to the rear opening of the main body front case 2 via a filter packing 15.

Reference numeral 16 denotes a blower, which is disposed at an appropriate position in the rear case 3 of the main body together with a cord reel 17 and the like via a vibration-proof rubber (not shown) or the like.

Reference numeral 18 denotes an exhaust port formed at a predetermined position at the rear of the rear case 3 of the main body.

In this embodiment, the garbage storage bag 13 is made of synthetic resin and is a commercially available plastic bag.

. The filter will be explained in detail according to FIG. 2 and FIG. 4B.

The dirt sucked in from the suction port 6 passes through the elbow 19 fixed to the hook part 9a of the filter case 9, enters between the pre-filter 8 and the dirt storage bag 13, and relatively coarse dirt is filtered by the pre-filter 8, and then passes through. The fine particles are captured by the main filter 7, and only clean air passes through the inside of the main filter 7 and is discharged from the blower 16.

According to this, the connection between the elbow 19 and the gripper part is made tangential, and the protruding part 9A of the filter case 9 is tilted to reduce the protruding amount of the lower part, so that the air flow rate in this part of the pre-filter 8 is reduced. Prefilter 8 quickly
There is no dust attached to the inlet, and since a rotating airflow is provided, the airflow can create a swirling cyclone effect, creating a double effect where dust accumulates from the opposite side (back side) of the inlet, which is highly effective in practical use. .

Conventionally, as shown in Fig. 4A, the connection between one elbow and hook portion 9a was made at right angles, so the airflow that was sucked in hit the prefilter 8 at right angles and was divided to the left and right. Dust easily adhered to the inlet, causing it to become clogged quickly.

The operation of the vacuum cleaner with the above-described configuration will be explained.

Suction port assembly connected to the main body of the vacuum cleaner (not shown)
The garbage that has passed through enters the garbage storage bag 13 through the suction port 6,
Relatively coarse dust is filtered by the pre-filter 8, and the fine dust that has passed through there is captured by the main filter, and only clean air passes through the main filter 7 and is sent to the blower 1.
6 is cooled and then discharged to the outside from the exhaust port 18.

Therefore, when disposing of dust after cleaning, first divide the main body into the front case 2 and the main rear case 3, and rotate the dust removal handle 12 of the filter case 9 in the main body front case 2 as shown in FIG. The dust-off vibrating body 11A and the pre-filter 8 attached to the main filter 7 rotate simultaneously, and the dust-off vibrating body 11A performs the dust-off operation of the main filter 7, completely falling into the pre-filter 8 and bag attachment frame 14. If the plastic bag serving as the garbage storage bag 13 is separated, it can be stored with the garbage stored inside.

In this case, the protruding part 9A of the filter case 9 is inclined so that the protruding amount at the bottom is smaller than the upper part, so when removing dust, the coarse dust stuck between the protruding part 9A and the pre-filter can also be removed from the pre-filter. By rotating 8, it easily falls into the garbage storage bag 13.

According to the present invention as described above, the garbage that has been sucked in is accumulated and stored in the garbage storage bag, and the garbage storage bag can be taken out and disposed of together with the collected garbage, thereby making it possible to dispose of garbage easily and hygienically. The accumulation and storage of garbage in the garbage storage bag is achieved by making the protrusion of the lower part of the protrusion smaller than that of the upper part, which reduces the rate at which garbage accumulates between the filter and the protrusion, and also makes it more likely to fall into the garbage storage bag. It is very practical and can be done effectively.
