Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a filter assembly in which a filter is housed in a freely foldable filter case.

Conventionally, filters have been housed and mounted in fixed filter cases that cannot be expanded or folded.

This is to ensure perfect adhesion between the filter and the filter case and to improve sealing performance.

By the way, it is extremely advantageous from the viewpoint of transportation, storage, and cost to make the filter case foldable to reduce its bulk and to make the filter replaceable.

SUMMARY OF THE INVENTION An object of the present invention is to provide a convenient filter assembly by improving the framework of a filter case, making the filter case foldable, and making the filter detachable.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described below with reference to the drawings showing one embodiment.

FIG. 1 shows the assembled state of the filter assembly of the present invention, in which a filter case 1 houses a filter 2 of an accordion type or other appropriate type.
Both ends of the filter 2 are held on the top plate 3 and bottom plate 4 of the filter case 1 by holding members 5, and the pocket 6 of the filter 2 is further held by fingers 7.

The above-described filter assembly is applied to a duct mechanism of an air treatment system, and each component will be described in detail next.

In the filter case 1, as shown in FIG.
It is configured by being attached to 1.

Although the hinge mechanism 10 of the illustrated embodiment is formed by bendable thin-wall molding of synthetic resin, it may also be implemented using a separate hinge or the like.

A reinforcing bar 12 is formed on the top plate 3 and the bottom plate 4, and an outward flange 13.13 is provided in a protruding manner, and a pin 14 is further provided on the outside.

Inward flanges 16 and 16 having reinforcing bodies 15 are protruded from the left and right side plates 8 and 9.
A pin 1 attached to the top plate 3 and bottom plate 4 is attached to the side edge of the
4 protrudes, and furthermore, the left and right side plates 8
, 9 is provided with a sealing mat 18.

An inward flange 21 having an inward flange 19 and a reinforcing body 20 is protruded from the frame 11, and a reinforcing member 23 having a fixing portion 22 for the top plate 3 and bottom plate 4 is provided at approximately the center of the frame 11. .

The holding member 5 has a flange 2 with grooves 24 formed at appropriate intervals.
5. It consists of a clamping body 26, an outer leg body 27, and an inner membrane body 28, and the outward flanges 13.13 of the top plate 3 and bottom plate 4
The end portion of the filter 2 is held in place.

The finger 7 is constructed by forming a plurality of comb teeth 31 protruding from a thin material 30 having a protruding end portion 29 .

Next, the case of assembling the filter assembly of the present invention having the above structure will be explained.

First, as shown in FIG. 2, the bottom plate 4 is erected and the reinforcing material 23 is
, and then raise the right side plate 9 and attach the bottom plate 4.
The fastening body 17 of the inward flange 16 is engaged with the pin 14 of the upper plate 3, and the upper plate 3 is raised up and fixed with the fastening part 22 of the reinforcing member 23. The protruding fastening body 17 is engaged with the inward flange 16 of.

Next, the filter 2, which is expandable and retractable in accordion style, is housed in the filter case 1, and the filter pleats at both ends are engaged with the outward flanges 13, and between the outer leg body 27 and the inner membrane body 28 of the holding member 5. Insert and attach to the outward flanges 13 of the top plate 3 and bottom plate 4.

Then, the left side plate 8 is erected, and the fastening bodies 1717 of the inward flange 16 are engaged with the pins 14 of the bottom plate 4 and the pins 14 of the top plate 3 and fixed.

At this time, the left and right ends of the filter 2 are pressed by mats 18 provided on both side plates 8 and 9.

Since the mat 18 is made of an elastic material such as glass fiber or synthetic fiber, the left and right ends of the filter 2 are inserted into the mat 18 and held, and the seal is completely sealed.

Further, the upper and lower ends of the filter 2 are sandwiched between the outward flanges 13 of the top plate 3 and the bottom plate 4 by the holding member 5, so that
It is completely sealed and is easy to put on and take off.

Next, the fingers 7 are inserted into the filter case 1 so that the comb teeth 31 of the fingers 7 are respectively arranged in the pockets 6 of the filter 2, and the protruding ends 29 of the fingers 7 are inserted into the filter case 1.
into the groove 24 of the holding member 5 and the clamping body 26.

In the embodiment, the fingers 7 are attached at five locations on the holding member 5, but they may be attached at appropriate locations to the extent that the filter 2 does not shrink.

In the above assembly operation, the filter case 1 was assembled by standing up the bottom plate 4, right side plate 9, top plate 3, and left side plate 8 in this order, but this order may be changed.

However, either the left side plate 8 or the right side plate 9 must be placed last.

Incidentally, when unfolding the filter assembly, the above-described assembly operation may be performed in reverse, but it is also possible to replace the filter 2 with the filter case 1 assembled.

That is, either the left side plate 8 or the right side plate 9 is disengaged from the top plate 3 and the bottom plate 4, the side plate is tilted, the right and left sides of the filter 2 are released from close contact, and then the holding member 5 is moved to the top plate 3. and the filter 2 pulled out from the outward flange 13 of the bottom plate 4.
can be removed.

As mentioned above, the filter assembly of the present invention is
The filter case 1 and the filter 2 can be used as foldable and removable units, and can be used for transportation, storage, and the filter 2.
It is extremely inconvenient in terms of replacement etc.
