DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter used for an air conditioner installed in a room such as an automobile, an office, a hospital, and a home.

[0002]

2. Description of the Related Art FIG. 10 shows a filter used in an air conditioner. This filter 19 has a frame 19
a and a folded filter material portion 19b. The frame portion 19a includes a resin frame 20 and a filter material portion 19b.
Is mounted inside the frame 20. Frame 2
An elastic body 21 such as urethane is provided on the side surface of the elastic member 0 for the purpose of preventing vibration from a duct or an air conditioning circuit to which the filter 19 is mounted or filling a gap between the duct 19 and the like. Frame 20
Is provided with a projection (handle) 20a for removing the filter 19 from a duct or the like.

[0003]

However, in the conventional filter, since the filter member and the frame are configured as separate parts, the number of parts and the number of assembling steps are increased. In addition, since the frame is a resin molded product, a mold is required and the cost is increased. However, if the filter is constituted only by the filter material part without the frame, the rigidity of the filter is insufficient, and there is a possibility that the predetermined shape cannot be maintained in the air conditioner, and there is a possibility that the attachment and detachment may be hindered. is there.

Therefore, the present invention can sufficiently reinforce the filter medium portion without using a resin frame, and can reduce the man-hour required for manufacturing and assembling the resin frame, thereby reducing costs. It is intended to provide a simple filter.

[0005]

Hereinafter, the present invention will be described. In addition, in order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are added in parentheses, but the present invention is not limited to the illustrated embodiment.

The filter (1) of the present invention is affixed to a folded filter material portion (2) and at least a side surface (2b) of the outer periphery of the filter material portion along the direction of the folding of the filter material portion. A reinforcing member (3), and a handle (3a) that is foldable on the outer periphery of the filter medium portion is provided on a part of the reinforcing member.

According to the present invention, a reinforcing material such as tape, urethane, nonwoven fabric, or the like is stuck instead of the resin frame, so that it is necessary to manufacture and assemble the frame while sufficiently reinforcing the filter member. Man-hours can be reduced and cost can be reduced. When removing the filter from the duct or the like of the air conditioner, the filter can be easily pulled out by raising the handle provided on the folded reinforcing member. Since the handle provided on the reinforcing material is folded over the outer periphery of the filter material portion, the reinforcing material does not cover the folds of the filter material portion, and the folding portion is easily caused when the filter is housed in the device. be able to. The length of the folded portion of the reinforcing material can be sufficiently secured. Further, a handle provided on the reinforcing member may extend the reinforcing member and be formed as an extension.

[0008] The reinforcing material is attached to both sides of the filter material portion along the fold direction, and a part of each reinforcing material protrudes from the end face (2c) of the filter material portion in the fold direction to function as the handle. You may make it.

According to the present invention, the filter member can be sufficiently reinforced by attaching the reinforcing member having the handle to both side surfaces of the filter member. When the filter is removed from a duct or the like of the air conditioner, the filter can be easily pulled out by using a handle provided on the reinforcing member. In addition, since handles are provided on both side surfaces of the filter medium portion, the force applied to the handle when the filter is pulled out is evenly distributed on both side surfaces of the filter medium portion, so that the effect of preventing damage to the filter and breakage of the reinforcing material is enhanced. . Further, the filter can be taken out straight by pulling both handles evenly.

[0010] The ends of the handles folded on the outer periphery of the filter medium portion may be connected to each other.

According to the present invention, the reinforcing members folded on the end surfaces of the filter member are joined to each other to prevent the reinforcing members from floating from both end surfaces.

[0012] The reinforcing material (16) is attached to at least a side surface of the outer periphery of the filter material portion along the fold direction of the filter material portion, and a cutout (1) is formed in a part of the reinforcing material.
8) may be provided to function as the handle.

According to the present invention, it is necessary to cover the outer periphery of the filter medium portion with a reinforcing material and to provide a cutout in a part of the reinforcing material, and the cutout can be used as a handle. Cost can be reduced because the number of man-hours can be reduced. When removing the filter from the duct or the like of the air conditioner, the filter can be easily pulled out by bending the handle of the notch along the cut line and causing it. In addition, since the handle is a part of the reinforcing member, it does not become an obstacle if it is returned after bending.

[0014] The filter member and the reinforcing member may be made of the same material.

According to the present invention, since the filter is made of the same material as the filter medium portion and the reinforcing material, it is not necessary to separate the components constituting the filter when the filter is reproduced as a recycled product. It will be easier.

[0016] The reinforcing material may be provided with a sealing material (4).

According to the present invention, when the reinforcing material does not have a sealing property, such as a tape-like reinforcing material, the sealing material is provided on the surface of the reinforcing material, so that the filter can be connected to the duct or the air conditioning circuit. When housed inside, it is possible to enhance the adhesion of the installation surface between the filter and the duct or the like.

[0018] The reinforcing material itself may have a sealing property.

According to the present invention, parts constituting the filter can be simplified by using a material having a sealing property for the reinforcing material itself, such as urethane or nonwoven fabric.

Further, a notch (21) may be provided in a part of the reinforcing material attached to the side surface along the folding direction.

According to the present invention, since the filter can be deformed by bending or the like, the filter can be flexibly adapted and mounted according to the filter mounting shape such as a duct.
