Description

[Detailed description of the invention] [Industrial application field] The invention is used in the technical field such as a dust collector and a vacuum cleaner, and specifically, is applied to the above-described dust collector and the vacuum cleaner. The present invention relates to improvement of a preferable filter mounting portion.

[Conventional technology]

In large dust collectors that use multiple filters, the work of installing or replacing the filters in the dust chamber,
It was very difficult and troublesome because the dust chamber was small and the inside was dark and dusty.

Therefore, the present applicant has filed a Japanese Patent Application No. 56-5898 (Japanese Utility Model Application No.
No. 173819) has proposed a dust collector in which the installation and replacement of the filter can be performed very easily and reliably.

The dust collector according to the above-mentioned application is provided with a bracket for hooking and supporting the tip of the mounting plate on the inner wall surface of the dust chamber into which the mounting plate on which the filter is mounted is inserted. After holding the mounting plate with both hands in both hands and inserting it into the dust chamber, and hooking the tip of the mounting plate to the bracket, the entire mounting plate is connected to the vent of the filter and the venturi mounted on the partition plate. It is configured such that it is aligned and pressed against the bottom side of the partition plate, and then the root end side of the mounting plate is screwed to the partition plate side.

[Problems to be solved by the invention]

According to the dust collector described above, the filter can be mounted with the ventilation port thereof closely attached to the venturi port provided on the partition plate, so that the air for dust removal blown into the venturi from the blow pipe is leaked to the outside. Instead, the dust can be blown into the inside of the filter through the ventilation hole to remove dust adhering to the filter.

However, the dust chamber for installing the filter is very narrow and dusty as described above, and it is dark, so while supporting the mounting plate with the heavy filter by hand, search for the bracket and hook the tip Further, it is very troublesome to align the vent of the filter with the venturi, and align the screw holes of the mounting plate with the screw holes of the partition plate, and screw the mounting plate to the partition plate side. In addition, there is a problem that the installation requires a lot of time and labor in addition to a skilled technique.

Therefore, a technical problem of the present invention is to make it easy and smooth for anyone to mount the above-mentioned filter.

[Means for solving the problem]

The interior of the fuselage is divided into two rooms, a clean room and a dust room,
In addition, on the bottom side of a partition plate on which a venturi for blowing dust-removing air is mounted on the upper surface, a filter mounting plate on which a filter is mounted is aligned with the venturi opening with a packing interposed between a filter vent and a gas vent. In a dust collector configured so that dust can be blown into the filter through a venturi by dusting by screwing, dust adhering to the filter can be wiped off. On the bottom surface of the partition plate, a pair of right and left support frames that guide the insertion of the mounting plate by supporting both guide edges of the mounting plate from both sides on the bottom surface of the partition plate while forming a guide edge by bending downward. On the other hand, the filter and the filter mounting plate including the guide edge are arranged in parallel with a vertical interval larger than the thickness of the entire filter mounting plate. Guide the leading edge of each guide edge according to the insertion of the mounting plate, raise the leading end of the filter mounting plate toward the bottom surface of the partition plate, and mount the venturi and the packing attached to the ventilation port of the filter. An inclined portion for preventing insertion of the filter mounting plate is provided at a position where each port, the rear end side of the filter mounting plate and each screw hole for screwing formed on the partition plate coincide with each other.

(2) The tip of the guide edge formed by bending both sides of the filter mounting plate downward is a round surface, and the tips of the support frames juxtaposed on the bottom surface of the partition plate are on the top surface. On the inner wall surface of the body of the dust collector, a bracket having an inclined surface having the same inclination angle as that of the front end inclined surface is attached to the inner wall surface of the body of the dust collector.

[Action]

 The above means works as follows.

According to the means described in (1) above, the filter mounting plate on which the filter is mounted is very easily dusted with little sliding resistance in a state where both guide edges are guided by the left and right support frames provided on the partition plate. It can be inserted into the room, and at the final stage of the insertion, the tips of the two guide edges are guided by the inclined portions formed at the tips of the left and right support frames and rise toward the bottom surface of the partition plate, In addition, the insertion of the gasket is stopped at the position where the opening of the packing attached to the vent of the filter is aligned with the opening of the venturi, and the screw holes for screwing formed on both the filter mounting plate and the partition plate are aligned. In this state, push up the root end side of the filter mounting plate and press it against the bottom of the partition plate and screw it down. Let's install It is one that can, therefore,
In a narrow and dark dust chamber, the filter can be mounted very simply and accurately by simply pushing the filter mounting plate.

According to the means described in the above (1), the vertical spacing between the left and right support plates with respect to the bottom surface of the partition plate is configured to be wider than the entire thickness of the filter mounting plate including the packing and the guide edge. When the packing is inserted, the packing is brought into contact with the bottom surface side of the partition plate, so that there is no fear of breakage or misalignment, and the packing can be surely aligned with the venturi opening.

The element described in the above (2) is such that even if the tip of the guide edge hits the inclined surface of the support frame due to the insertion of the mounting plate, the tip of the guide edge is formed on the round surface, The insertion can proceed smoothly without being locked on the inclined surface, and the inserted filter mounting plate is guided by the inclined surface of the support frame and the inclined surface of the bracket provided on this extension line, and rises sequentially. Eventually, the tip arm surface of each guide edge is pressed against the bracket, and the insertion is stopped with the packing port attached to the filter vent aligned with the venturi port, and the filter is smoothly stopped. And accurate mounting.

As described above, the technical problems described above can be solved by the above means, and the problems of the conventional technology can be solved.
