Description

Air filter for air conditioner {AIR FILTER FOR AIR CONDITIONING}

As a conventional air filter for this type of air conditioner, a main body box in which an air inlet is formed on one side and an air outlet on the opposite side is manufactured, and the filter filter material is removed between the air inlet and the air outlet in the main body box. There are ones that are arranged in a shape and attached integrally with an adhesive.

In recent years, instead of directly attaching only the filter filtration material directly to the main body box, a plurality of filter main bodies are formed to surround the outer circumference of the filter filtration material with a filter frame, and the plurality of filter main bodies are arranged in a main body box in a zigzag shape. Some say that.

However, in the above-described air conditioner air filter, in which the filter filtration material is integrally bonded to the main body on the main body like the former, it is disposed of by only one use, which leads to an increase in the generation of garbage as a form of use once. Not only that, it was the height of the economy.

Like the latter, if the filter body is manufactured to enclose the outer circumference of the filter filter material with a filter frame and the filter body can be detached and placed in the main body box, the main body box and the filter main body can be separated, so that only the filter main body is cleaned. In addition, it is possible to save resources and reduce waste by enabling exchange.

However, in the filter body which can be taken out from the box body in this way, if there is a gap between the inside of the filter frame and the outer circumferential terminal of the filter filter material, air is leaked from the gap without being filtered and the filtration efficiency of the air is reduced. In order to reduce, the above air leakage is prevented by integrally attaching the outer circumferential terminal of the filter filtration material with an adhesive to the inner circumference of the filter frame.

For this reason, the filter frame and the filter filter material cannot be completely separated, and only the filter filter material is difficult or impossible to replace or regenerate the filter frame, and the filter frame remains attached even when cleaning or cleaning the filter filter material. It could not be washed.

It is an object of the present invention to provide an air conditioner for an air conditioner capable of cleaning, cleaning or replacing only the filter main body comprising the filter filter material and the filter frame, thereby saving resources, reducing waste, and reducing costs.

It is also an object of the present invention to provide an air conditioner for an air conditioner capable of simplifying cleaning, cleaning or replacement of filter filters only, and regeneration of filter frames.

The present invention relates to an air filter for use in an air conditioner installed in a building or the like.

The air filter for an air conditioner of the present invention can be made into and out of a main body box formed by opening an air inlet on one side and an air outlet on the opposite side, and between the air inlet and the air outlet in the body box. It is provided with a filter body that is stored.

In addition, the filter main body is inserted into the filter frame in which a cross-sectional frame-shaped frame member is formed into a quadrangular shape so as to remove a bellows-shaped filter filter material in which a plurality of acid portions are continuous.

Said filter filter material integrally forms the sealing member which fills the valley part between the front and back surfaces of the both ends of the width direction which cross | intersects perpendicularly to the continuous direction of a mountain part, or between the mountain parts adjacent to one side, in the continuous direction of a mountain part, The sealing member causes the gap between the end face of the groove-shaped frame member and the above-described widthwise both ends to be fitted thereto to be closed.

According to the air filter for an air conditioner configured as described above, since the filter main body is accommodated in and out of the main body box, the filter main body can be removed from the main body box and can be easily cleaned, cleaned or replaced, and reused.

The sealing member which closes the clearance gap between the width direction both ends of the said bellows-shaped filter filter material, and the inside of the groove | channel of a groove-shaped frame member is integrally formed only at the filter filter material side, and a cross-section is a groove-shaped frame | membrane. It is in a bonding relationship that can be separated even if it is in close contact with the inner surface of the groove of the member.

Therefore, air is not leaked from the gap between the widthwise both ends of the filter filter material and the cross section between the grooves of the groove-shaped frame member without being filtered out. Moreover, the bellows-shaped filter filter material has a groove-shaped frame member. It can be easily removed from the grooves of the filter, making it possible to clean, clean or replace only the filter filter material, and to reclaim and use only the filter frame of which the useful life is old.

Since the sealing member is formed integrally with the filter filtration material, it is possible to obtain a state in which both ends of the width direction of the filter filtration material are inserted into the grooves of the groove-shaped frame member, and at the same time, the gap between them is sealed. Apart from the need for sealing work.

Therefore, the assembling work of the filter body, in particular, the attachment and detachment of the filter filter material to and from the filter frame during cleaning, cleaning or replacement of only the filter filter material is efficiently performed.

Moreover, the said sealing member in the air filter for air conditioners of this invention is formed so that it may become slightly higher than the depth of the valley part of the width direction both ends of a filter filter material.

According to the sealing member formed in this way, even when there are some dimension nonuniformity between the groove width of a groove-shaped frame member, and the height dimension of the mountain part of the width direction both ends of a filter filter material, the width direction of a filter filter material is formed. Both ends and the cross section can seal the gap between the groove of the frame-shaped member and the groove.

In this case, the use of polypropylene resin as the material of the sealing member provides proper elasticity, so that the cross section can be brought into close contact with the groove of the groove-shaped frame member without gaps, and the sealing effect is increased and the weather resistance is excellent. Since the adhesiveness to a filter filter material is also excellent and it does not peel easily, it is advantageous.

As the material of the filter filtration material, polyolefin fibers are used to withstand washing well, and it is easy to wash off the adhered dust particles.

1 and 2, this air conditioner air filter includes a main body box 1 and a plurality of filter main bodies 2 housed in the main body box 1 so that entry and exit are possible.

The main body box 1 has an air inlet 3 on the front side and an air outlet 4 on the back side, and the top side is a ceiling plate 5, the bottom side is a bottom plate 6, and the left and right side sides are left and right sides. It is occluded by the face plates 7 and 8, respectively.

For the top plate 5, the bottom plate 6 and the left and right side plates 7 and 8, metal plates such as steel sheets, synthetic resin molded bodies or wood can be used.

As shown in FIG.3 and FIG.4, the filter main body 2 is made by inserting the filter filter material 10 into the filter frame 9 of a square shape.

The filter frame 9 is formed by cross-assembling the groove-shaped frame member 11 in a quadrangular shape made of plastic such as ABS resin.

The cross-sectional groove-shaped frame member 11 is adapted to detach the left and right split frames 111 and 112 so as to be detachably joined, and each split frame 111 and 112 has a cross section L (L). The upper and lower frames 111a, 112a, 111b, 112b and the front and back frames 111c, 112c, 111d, and 112d are formed into a quadrangular frame shape.

Top and bottom frame 111a, 112a, 111b, 112b and front and back frame 111c, 112c, 111d, 112d by facing the right and left split frames 111, 112 Each cross section represents a groove shape.

As the material of the filter filter material 10, synthetic fibers are used. Among the synthetic fibers, polyolefin-based fibers such as polyethylene fibers and polypropylene fibers, which are particularly resistant to washing and are easy to wash off the adhered dust particles, are used.

The filter filter material 10 is comprised by making a polyolefin fiber into a cloth of nonwoven fabric, knitted fabric, woven fabric, or the like, as shown in FIG. 4, by bending a plurality of acid portions 10a into a continuous bellows shape.

Sealing members 12 made of polypropylene-based resin are adjacent to both sides of the bellows-shaped filter filter material 10 in the width direction intersecting at right angles to the direction in which the acid portion runs. It is formed integrally by coating the valleys 10b between the peaks 10a and 10a to be filled so as to dry solidify them.

As shown in Figs. 5 and 7, the filter filter member 10 is fitted so that the cross section can be separated between the right and left split molds 111 and 112 of the groove-shaped mold member 11. .

At this time, both ends of the width direction of the filter filter material 10 are fitted into the grooves of the groove-shaped frame member 11, and at the same time, a gap between the widthwise ends thereof and the inside of the groove of the groove-shaped frame member 11 is shown. A state in which the sealing member 12 is blocked is obtained.

In this case, the cross section of the filter frame 9 is the groove width W (see FIG. 7) of the groove-shaped frame member 11 and the height dimension H of the peaks 10a of the widthwise ends of the filter filter material 10 ( Even in the case where there is some dimensional non-uniformity, the widthwise both ends of the filter filtration member 10 and the cross section can be sealed in the gap between the groove of the groove-shaped frame member 11 and the above. The sealing member 12 is preferably formed to be slightly higher than the depth D (see FIG. 7) of the valley portion 10b of the filter filter material 10.

Since the filter filter member 10 can be folded in a bellows shape, the contact area of air with respect to the filter filter member 10 having a constant horizontal and vertical size can be increased as much as possible, thereby reducing the ventilation resistance.

In the filter frame 9, as means for removably combining the right and left dividing frames 111 and 112, as shown in FIG. 4, one of several places of the right and left dividing frames 111 and 112 is shown. The engaging projection 13 was integrally protruded, and the engaging projection 14 corresponding to the engaging projection 13 was drilled on the other side, and the engaging projection 13 was engaged with the engaging hole 14. A means for elastic engagement is adopted so that detachment is possible (see Fig. 9).

In addition, the filter medium holding protrusions 115 are provided at several places on each of the inner surfaces of the right and left split molds 111 and 112 so that the bellows-shaped filter filter material 10 does not move in the stretching direction in the filter mold 9. It protrudes integrally, and the top part of the mountain part 10a, 10a which adjoins the filter filter material 10 is engaged with this filter medium holding protrusion 115 (refer FIG. 9).

Thus, the right and left division frames 111 and 112 can be separated from each other by engaging the engaging projection 13 formed integrally with the partition frames 111 and 112 and the engaging holes 14. The filter medium holding protrusion 115 integrally formed on the split molds 111 and 112 in a same shape and separates from the filter mold 9 by regulating the movement of the filter filter material 10 in the stretching direction. It is not necessary to prepare specially the coupling members and the movement restricting members of the members, and thus the number of members and the number of assembly work can be reduced, and even when regeneration is used in the disposal of the filter frame 9, the separation operation of the foreign members can be performed. Since it can omit, it becomes easy to reproduce and use by that much.

Moreover, the left and right dividing frames 111 and 112 shown in FIG. 4 are all formed in the same shape, and can be mutually made upside down.

As shown in Figs. 1 and 6, the filter main body 2 is mounted so as to be accessible from the front side of the main body box 1 such that the filter main body 2 is arranged in the shape of the left and right in the main body box 1 in the left and right directions.

The guard rails 16 and 16 arranged in parallel on both the left and right sides are fixed in the shape of a hook, while the upper ends of the upper frames 111a and 112a of the filter frame 9 of each filter body 2 are fixed. Slide grooves 17 having a convex cross section in which the slides are freely fitted to the guide rails 15 on the bottom and bottom surfaces 111b and 112b are formed over the entire length of the front and rear directions, respectively.

Before and after each of the right and left guard rails 16 and 16, the engaging projection piece 18 is protruded horizontally and the upper frame 111a of the filter frame 9 of each filter body 2 is installed. ), Engaging grooves 19 on which the slides are freely fitted to the engaging projection pieces 18 on both sides of the 112 and the lower frames 111b and 112b are formed over the entire length of the front and rear directions.

In this way, the filter main body 2 slides the upper and lower slide grooves 17 to the guide rails 15 between the guard rails 16 and 16 facing the upper and lower sides of the main body box 1, and thus the main body box 1 It is possible to move in and out smoothly in the front and rear inclination directions without derailing inside.

In addition, polymerization of each inner surface of the ceiling plate 5 and the bottom plate 6 of the main body box 1 and the upper frame 111a, 112a, the lower frame 111b, 112b of the filter body 2 is performed. The gap between the surfaces becomes a maze by fitting the guard rails 16 and 16 and the guide rail 15 and the slide groove 17, so that the air from the air inlet 3 is not filtered. The leakage to the outlet 4 side can be prevented as far as possible.

The presser body 24 connected by the upper and lower legs 22 and 23 can be inserted freely.

After inserting and storing the filter main body 2 into the main body box 1 and inserting the pressing frame 24 toward the front side of the main body box 1, the filter main body 2 is inserted into the front side of the main body box 1 and fixed. The front frame 111c, 112c of (2) is pressed, and the whole filter main body 2 is pressed against the rear vertical leg 20. As shown in FIG.

As shown in FIG. 6, each groove 20a, 21a of the rear leg 20 and the front leg 21 has an adjacent filter by embedding a cushion material 25 for preventing air leakage made of sponge rubber or the like. The inlet air leaks from the front part 111c, 112c of the main body 2 and the back part 111d, 112d of the main body 2 to the air outlet 4 side without being filtered. It is preventing.

In the air conditioner for the air conditioner of the above-described configuration, the air flowing from the air inlet (3) is cleaned by the filtration action of the filter filter material 10 of the filter body (2) and flows out of the air outlet (4).

6, the clearance gap between the width direction both ends of the filter filter material 10, and the cross section of the filter frame 9 with the inside of the groove of the groove-shaped frame member 11 is closed by the sealing member 12. As shown in FIG.
