Abstract

PROBLEM TO BE SOLVED: To easily judge clamping condition of a filter by providing a projected part on the inside of an opening/closing plate and making closing of the opening/closing plate possible only when its fixing by clamping with a screw, etc., is enough. SOLUTION: A packing 5a is mounted by adhesion on the top part of a filter 5 and the packing 5a is brought into contact with the partition plate 6 and is compressed and sealed by clamping force of a screw 3 through a filter holder 4. The top face of a projected part 1 provided on the inside of the opening/closing plate 2 is brought into contact with the underface of a filter holder 4 when clamping of the screw is enough. Therefore, when the clamping and fixing of the screw 3 is not enough, the projected part 1 collides with the folding part 4b of the filter holder 4 and the opening/closing plate can not be closed and, on the contrary, when the clamping and fixing of the screw 3 is enough, the opening/closing plate 2 can be closed. It is possible thereby to judge easily and visually the condition of clamping and fixing of the filter 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage part of a dust collector.

[0002]

2. Description of the Related Art A conventional filter fixing method is a partition plate 6
The filter 5 sandwiched by the filter holder 4 was fastened and fixed by using the screw 3 or the like.

[0003]

In the filter fixing method described above, since the degree of tightening and fixing is determined only by the feeling of the fingertip of the person who tightens the screw 3 or the like, there are cases where the tightening and fixing are insufficient, and the gap caused by this is generated. There was a problem that dust 7 was blown out from 11.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a filter accommodating portion in which the tightening condition of the filter can be easily determined without depending on the feeling of the fingertip.

[0005]

The above object can be achieved by providing a protrusion on the opening / closing plate so that the opening / closing plate can be closed only when the screws and the like are sufficiently tightened and fixed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the dust collector according to the present invention will be described below with reference to the drawings. The air sucked together with the dust 7 from the fan 8 directly connected to the motor 2 is sucked into the suction port 9
Through the filter 5, the fan 8 and the discharge port 10. On the other hand, the dust 7 is filtered and collected by the filter 5. (See FIG. 9) When the filter 5 is inserted into the filter holder 4, it is stopped by the filter stopper 5b. This is inserted into the filter housing portion until the back side 4a of the filter holder hits the holder stopper 13, and is fixed by the screw 3 on the front side. A packing 5a is attached to the upper part of the filter 5 by adhesion or the like, and the packing 5a is contacted with the partition plate 6 and compressed and sealed by the tightening force of the screw 3 through the filter holder 4. The upper surface of the protrusion 1 provided inside the opening / closing plate 2 is in contact with the lower surface of the filter holder 4 when the screw 3 is sufficiently tightened. Therefore, if the screws 3 are not sufficiently tightened and fixed, the protrusion 1 cannot hit the folded-back portion 4b of the filter holder 4 to close the opening / closing plate 2. Conversely, if the screws 3 are sufficiently tightened and fixed, the opening / closing plate 2 is closed. be able to.

[0007]

According to the present invention, since the opening / closing plate of the filter housing portion is provided with the protrusion, it is possible to easily and visually determine the tightening / fixing condition of the filter. It is possible to prevent damage to the fan, motor, and other devices caused by dust blow-through and dust blow-through.
