Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dust collection device for a vacuum cleaner, and an object of the present invention is to provide a vacuum cleaner that is easy to handle and has a structure in which dust collected by a filter device is collected in a dust bag and thrown away. shall be.

In conventional vacuum cleaners, the dust collected by the filter device is collected in a dust box, and the dust is packed in a dust bag installed between the dust collection box and the filter device and disposed of. When the bag was placed in a dust collection box and the end was folded back into the opening of the dust collection box and the filter device was inserted, the end of the dust bag protruded outside the main body, creating an unsightly defect. Therefore, if the opening is made into a double wall and the end of the dust bag is pushed into this double wall, the end will not be visible from outside the main body, but the dust bag will be difficult to pick up when disposing of garbage, and the dust bag will not work properly. The disadvantage is that it is difficult to do.

The present invention provides a dust collector for a vacuum cleaner that solves these problems.

Hereinafter, one embodiment of the present invention will be described based on the drawings. Reference numeral 1 denotes a main body housing an electric blower 2, 3 a cord winding device, and 4 a dust collection box extending from the main body 1 and having an opening 5 on the top surface. Reference numeral 6 denotes a dust collection box lid that is removably attached to the opening 5 of the dust collection box 4, and the lower edge of this lid 6 has a
A lid packing 7 made of an elastic material such as rubber is attached to the inner peripheral surface of the dust collecting box 4. Further, the lid 6 is formed with a suction port 8 for sucking in dust-containing airflow, and a handle 9 is provided on the top surface. Reference numeral 10 denotes a filter frame that is suspended from the dust collection box lid 6 into the dust collection box 4, and a bearing 1 is provided approximately in the center of the filter frame.
A support shaft of a filter gear 12 is rotatably inserted into the filter gear 1 . A substantially cylindrical secondary filter 14 for fine dust collection having a corrugated filter medium 13 and a substantially disc-shaped primary filter 15 for coarse dust collection are fixed to the support shaft of the filter gear 12 by screws. has been done. Therefore, when the filter gear 12 rotates, both filters 14 and 15 are rotated. Reference numeral 16 is a dust removal plate which is fixed to the bearing 11 and whose tip abuts against the filter material 13, and which applies an impact to the corrugated filter material 13 to remove fine dust from the filter material 13.
It is made to fall from 3. 17 is a filter packing that prevents dirt from leaking between the secondary filter 14 and the filter frame 10, and 18 is a blocking packing attached to the filter frame 10, which is in contact with the outer peripheral surface of the primary filter 15. ,
This prevents coarse dust from entering the secondary filter 14 side. Reference numeral 19 denotes a connecting gear that transmits the rotational force of the cord winding device 3 to the filter gear 12 via the interlocking device 20. A dust collection box gasket 21 is fixed to the main body 1 to prevent air leakage even when the dust collection box lid 6 is attached. 22 is a dust bag having impermeability and flexibility;
and a filter device 23 consisting of a filter frame 10, a secondary filter 14, a primary filter 16, etc., and its edge is folded back to the outside at the opening 5. 24 is a suction hole that communicates the inside of the dust collection box 4 with the front side negative pressure part of the electric blower 2 through a communication pipe 25, and prevents the dust bag 22 from being pulled toward the filter device 23 side. be. Reference numeral 26 denotes a partition rib protruding from the bottom surface of the dust collection box 4, which is in contact with the filter frame 10 via the dust bag 22, so that the dust collection box 4
The interior is divided into a fine dust chamber 27 and a coarse dust chamber 28.
Reference numeral 29 denotes a bag storage part formed between the upper end 4a of the dust collection box 4 and a storage wall 30 formed inside this upper end, and the end of the dust bag 22 is inside this bag storage part 29. The dust bag 22 is inserted into the dust bag 22, and the dust bag 22 is inserted into the dust bag 22 so that the dust bag 22 is held in the vicinity of the end by the lid packing 7 and the storage wall 30.

In the above configuration, coarse dust is collected in the dust-containing airflow sucked in from the intake port 8 by the primary filter 15, and
The next filter 14 collects fine dust.

When disposing of garbage, when the dust collection box lid 6 is removed from the dust collection box 4, the filter device 23 is also removed at the same time. At this time, since the lid gasket 7 is elastically in contact with the storage wall 30 via the dust bag 22, the dust bag 22 is pulled upward by the lid gasket 7 (state in FIG. 2). Therefore, this dust bag 2
Holding the end of 2 (in the state shown in Figure 3), you can squeeze this end to trap dirt.

Next, when placing a new dust bag 22 in the dust collection box 4, the end of the dust bag 22 is inserted into the bag storage part 29 a little more. This prevents the end of the dust bag 22 from coming out from inside the bag storage section 29 when the lid packing 7 is inserted.

As described above, according to the vacuum cleaner dust collector of the present invention, when the filter device is pulled out from the dust collection box, the end of the dust bag is pulled up from the opening of the dust collection box by the lid gasket. This prevents the dust that is about to overflow from the dust collection box from spilling outside, and the end of the dust bag can be pulled upward, making it extremely easy to grasp, making it easy to use a vacuum cleaner for dust disposal. It is something that can be obtained.
