Abstract

PURPOSE:To fix easily the pitch of a filter medium and to facilitate the exchange of the filter medium by providing a folding filter medium, a cushion body to be attached to the filter medium, and a housing body for housing freely detachable said medium and body. CONSTITUTION:A filter medium 1 is formed by folding unwoven fabric, etc. A cushion body 2a is attached to both end parts of the filter medium 1 in the expanding and contracting direction of the medium, a cushion body 2b is attached in the direction vertical to said direction, and the uniformity of the pitch can be maintained. The filter medium is housed in each space 5 and 6 of a housing body 3, and fixed by the elasticity of the cushion body. A presser board 8 is engaged with an outer flange 9 to clamp the upper part of the cushion body. Beside, the lower part of the cushion body is supported by an inner flange 7. the filter medium can be exchanged only by removing the presser board.

Description

[Detailed description of the invention] 〔Technical field〕 This invention relates to an air cleaner.

[Background technology]

It is known that the filter media of conventional air purifiers are pleated in order to secure the entire surface area. Various means are used to maintain this pleated shape. For example, in the adhesion method, the pitch of the pleated filter medium is determined in advance so that the pitch is maintained. Prepare a comb with f'L7'c pitch, insert this comb into the filter medium, set it, and set it on the frame body to which the filter medium is attached. Then, in order to maintain airtightness between the frame and the filter medium, adhesive is poured into the gap between the filter medium and the frame, and after the adhesive dries and hardens, the comb is removed, and the filter medium with a fixed pitch is fixed to the frame. It is something that is retained. There is also an insert molding method, 25ζ, in which the entire adhesive part of the above method is soaked with molding material to fix it and maintain airtightness. Furthermore, a completely improved method of adhesion and insertion is shown in Japanese Utility Model Publication No. 54-144391, but this filter has a retaining part on the frame body in which the filter medium is set, which tightly contacts the side edges and middle part of the filter medium. , has a fixing means for pressing the retaining part after setting the filter medium in the retaining part.

There are various ways to fix the filter media as described above, but in order to determine the pitch of the filter media, the adhesive method requires setting in advance with a comb, and insert molding requires setting in the comb-shaped part of the mold. Furthermore, the system having a frame retaining part has the disadvantage that the workability of setting the filter medium in the retaining part is poor.

[Purpose of the invention]

The purpose of this invention is to make it easy to determine the pitch of the filter media, to easily attach the filter media to the frame, and to reduce the life of the filter media (which prevents them from getting dirty due to chips, etc.), and to make it possible to replace only the filter media. The purpose is to provide an air purifier.

[Disclosure of the invention]

The air purifier of this invention includes a filter medium having a pleated shape;
The apparatus includes a cushion body that is attached to the filter medium and maintains the folded shape, and a frame body that stores the filter medium in the attachment/detachment position via the cushion body. The elastic force of the cushion body secures it within the frame, and the pitch of the folded shape is ensured.Moreover, it is easy to attach and detach from the frame.
Materials can be easily replaced.

Embodiment An embodiment of the present invention will be explained based on FIGS. 1 to 5. That is, the filter medium 1 is formed by processing a non-woven fabric such as polypropylene into a folded shape, and the entire periphery of the cushion body 2, such as foamed urethane 3 and rubber or flocked material, i.e., the cushion body 28, is formed by processing a nonwoven fabric such as polypropylene into a folded shape. The cushion body 2b is attached to the outer surface of both ends in the direction of expansion and contraction (arrow A in FIG. It is made to protrude beyond the filter medium 1 in the partially enlarged view of the figure. The elasticity of the cushion body 2b maintains the shape of the folds 9 and the uniformity of their pitches. The frame body 3 is partitioned into two spaces 5.6 by a partition plate 4, and each space 5.6 is divided into two spaces 5.6 as described above.
Material 1 is stored. This frame body 3 is set to have a dimension slightly shorter than the filter medium 1 in the unfolded state (state before assembly) shown in FIG. 1 to the extent that the elastic force of the cushion body 2b is generated.
The lower part of the seven bodies 2 is supported by the round brim 7 of the frame body 3. At this time, the center part of the filter medium 1 tends to pop out from the frame body 3 due to the elastic force of the cushion body 2, but the presser plate 8 of the frame body 3
The holding plate 8 holds the upper part of the 27757 body 2 in a pinched state. In this way, the filter medium 1 is housed in the frame body 3 via the cushion body 2. The companion cushion body 2a is in close contact with the inner surface 10a of the side wall 10 and the partition wall 4 as shown in FIG. It is completely sealed. On the other hand, when removing the filter medium 1 for replacement or the like, the holding plate 8 can be removed.

FIG. 5 shows a state in which the filter Glock, which is a filter body constructed in this manner, is assembled into an air purifier.

13 is a fan casing that holds a motor 15 with a fan 14 attached, 16 is a discharge port, and 17 is a suction port grill plate.
A filter block 19 is fitted into a removable groove in the fan casing 13 inside the fan casing 13, and a deodorizing filter 20 is provided on the fan side of the filter block 19. 21 is a grill plate mounting screw, and 22 is a hanging metal fitting.

When the motor 15 operates and the fan 14 rotates, air is sucked through the entire suction log grille plate 17 and the f1 pre-filter 18.
The filter medium 1 of the filter block 19 has a cleanliness of n%, and the deodorizing filter 20 has a deodorization level of n%, and is discharged from the discharge port 16.

With this configuration, the pitch setting and holding of the filter medium 1 can be easily done by the cushion body 2, and the filter medium 1 and the frame body 3 can be easily set and held.
The seal with is the cushion body 2a.

2b, which can be easily achieved.In addition, only the filter medium 1 can be replaced, the frame 3 can be reused, and furthermore, it is easy to assemble.

[Effects of the Invention] According to the present invention, the cushion body can be easily attached to and detached from the whole frame of the filter medium and can be easily replaced, and the pitch of the pleated shape can be determined at equal intervals.
