Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dust collector for a vacuum cleaner, and an object of the present invention is to enable sanitary garbage disposal.

Many conventional general vacuum cleaners have a filter device installed inside the dust collection box, and in this case, when disposing of dust, the filter device inside the dust collection box must be removed and the garbage inside the dust collection box must be disposed of. There were problems with unhygienic conditions, such as scraping out fine dust when removing the filter device and raising cotton dust inside the dust collection box. In order to solve this problem, as shown in FIGS. 1 to 3, the outer sides of the rotatable secondary filter 1 and primary filter 2 are wrapped in an air-impermeable bag 3 made of vinyl or the like. Next, collect dust in the space between the filter 2 and the bag 3, and when disposing of the garbage, turn the handle 4 as shown in FIG. There was a vacuum cleaner that could be used for hygienic disposal of garbage by removing it.In this case, the suction port 7 formed in the dust collection box 6 and the suction port 7 formed in the filter case 5
It is equipped with a communication pipe 8 that is connected to the dust collection box 6, and when the dust is sucked in until the indicator operates, and when the dust has accumulated near the suction port 7, the filter device is removed from the dust collection box 6 in order to dispose of the garbage. 7 and the communication pipe 8 were separated, and at this time, the dust accumulated in the suction port 7 sometimes fell into the dust collection box 6 (see FIG. 2). Further, as shown in FIG. 3, since the communicating pipe 8 is directed downward when trash is being disposed of, the dust accumulated in the communicating pipe 8 sometimes falls out at this time.

The present invention is capable of solving the above-mentioned problems all at once, and the present invention will be explained below based on the drawings (Figs. 4 to 8) showing an example of implementation. In the figure, 11 is a main body incorporating an electric blower 12, a cord reel 13 for winding a power cord, etc., and 14 is a lid rotatably supported on the upper end of the main body 11 about a shaft 15. Reference numeral 16 denotes a dust collection box with an opening at the upper end that is removably provided to the main body 11, and a suction port 1 is provided at the upper end of a filter case 17 that serves as a lid for the opening of the dust collection box 16.

Reference numeral 19 denotes a handle in which a shaft portion 21 is supported by a bearing portion 20 of the filter case 17. At the tip of this shaft portion 21, a bearing portion 22a of a filter 22 with a corrugated cross-sectional shape for collecting fine dust is attached to a screw 23. It is tightened and fixed. Further, a leaf spring 24, which is a dust remover, is attached to the bearing portion 20 of the filter case 17 so as to be in contact with the filter 22. Reference numeral 25 denotes a cylindrical prefilter for collecting coarse dust, and a flange portion 27 of the prefilter 25 is fixed to a flange portion 26 of the filter 22. Also, the lower end of the pre-filter 25 is the dust collection box 1.
It comes into contact with a gasket 29 fixed to a circular groove 28 formed in 6. 3
0 is an air-impermeable plastic bag, the opening of which is fixed to the upper part of a flange 31 formed on the filter case 17 with a rubber ring 32. By the way, a claw portion 33 is formed at the upper center end of the handle 19, and this claw portion 33 is connected to a gear 3 supported by a shaft 34 formed on the lid 14.
It engages with the claw portion 36 of No. 5. The gear 35 meshes with an intermediate gear 37, and the intermediate gear 37 meshes with another gear 38.

A pawl portion 41 is provided at the center of rotation of the gear 38 and engages with a pawl portion 40 of the clutch 39 which rotates as the cord reel 13 rotates. Further, the intermediate gear 37 has a flange portion 42 on the peripheral edge of the lower surface.
is formed to support the two gears 35 and 38 from below. Reference numeral 43 denotes a receiving portion formed to protrude horizontally from the main body 11, and supports the lower surface of the dust collection box 16. 44 is a locking rib attached to the dust collection box 16, and when the dust collection box 16 is placed on the receiving part 43 and combined with the main body 11, this rib 44 is adapted to be locked with the receiving part 43. There is. 4
Reference numeral 5 denotes a buckle attached to a handle 46 provided on the top surface of the lid 14 in order to allow the lid 14 and the dust collection box 16 to be attached and detached. 47 and 48 are the lid 14;
and gaskets fixed at the openings of the dust collection box 16, respectively, to ensure air tightness around the suction port 18 and between the lid 14 and the dust collection box 16. Reference numeral 49 denotes a gasket fixed to a groove 50 formed at the upper end of the pre-filter 25, and this gasket 49 comes into contact with the lower surface of the upper end of the filter case 17 to create an airtight gap between the pre-filter 25 and the filter case 17. doing. 51
is a gasket attached to the upper edge of the filter case 17, and this gasket 51 is attached to the dust collection box 16.
and the filter case 17 are air tight. Reference numeral 52 denotes a handle provided on the dust collection box 16 for pulling out the dust collection box 16 from the main body 11;
3 and 54 are front wheels and rear wheels attached to the lower end of the main body 11 (including the receiving portion 43).

In the above configuration, the dust-containing airflow flowing through the suction port 18 is purified by collecting coarse dust in the prefilter 25 and fine dust in the filter 22, and the purified airflow flows inside the lid 14. The air is discharged to the outside of the main body 11 via the electric blower 12. During this cleaning, the power cord is pulled out from the cord reel 13 and connected to the outlet.

When cleaning is completed, this power cord is wound onto the cord reel 13. Next time when cleaning, when the power cord is pulled out from the cord reel 13, the cord reel 13 rotates, and this rotation is caused by the clutch 39.
→ Gear 38 → Gear 37 → Gear 35 → Handle 19
This causes the filter 22 attached to the shaft portion 21 of the handle 19 to rotate. At the same time, the pre-filter 25 also rotates, whereby the coarse dust adhering to the pre-filter 25 is peeled off due to frictional resistance with the coarse dust accumulated in the plastic bag 30. Further, the fine dust adhering to the filter 22 falls from the filter 22 as the filter 22 vibrates with the leaf spring 24 fixed to the filter case 17 as the filter 22 rotates. As a result, the suction force, which had been reduced due to fine dust and coarse dust adhering to the filter 22 and prefilter 25, is restored. Next, after cleaning several times and sucking in dust until the indicator (dust meter) of the vacuum cleaner is activated, the dust accumulated inside the plastic bag 30 will be removed from the suction port 18.
It accumulates inside. Next, to dispose of garbage, press the buckle 45, open the lid 14 as shown in FIG. 7, and lift the handle 19 as shown in FIG. As the pre-filter 25 rotates, the coarse dust adhering to the pre-filter 25 inside the plastic bag 30 is subject to frictional resistance with other coarse dust, centrifugal force due to the rotation of the pre-filter 25, and grain weight of the coarse dust. etc., and then the plastic bag 30 can be removed from the filter case 17 to dispose of garbage. By the way, in the conventional vacuum cleaners shown in FIGS. 1 to 3, there was a problem in that the dust accumulated near the suction port fell when the garbage was disposed of, but according to the present invention, the dust is removed from the filter case 5 as in the conventional vacuum cleaner. Unlike connecting the formed communication pipe 8 and the suction port 7 formed in the dust collection box 6, the filter case 17 has a suction port 1 to which the hose is connected.
8 are integrally formed, there is no problem as in the conventional case.Furthermore, according to the present invention, the suction port 18 is oriented horizontally. It also solves the problem of falling dust that has accumulated nearby. Incidentally, garbage can be easily thrown away even if the hose is connected to the suction port 18.

The present invention can be carried out as described above, and by integrally providing a suction port for connecting a hose to the filter case, there is no possibility of dust falling when disposing of garbage, and after removing the filter case, it is possible to prevent dust from falling due to the rotation of the filter device. Even if dust removal is performed, the dust will only fall within the bag, allowing sanitary garbage disposal.
