Description

  The present invention relates to an air filter incorporated in an air conditioner or the like and disposed of after use.

  Conventionally, this type of air filter is known in which four rims of a filter medium formed by pleat folding are surrounded by a frame (see, for example, Patent Document 1).

  Hereinafter, the air filter will be described with reference to FIGS. 15 and 16.

  As shown in the figure, a frame is formed by the side plate 101, and a lower frame 103 in which a frame side 102 for loading the filter medium is extended on the lower surface, a filter medium 104 accommodated in the lower frame 103, and a side plate 105. An upper frame 107 is formed on the top surface of the frame frame 106 for holding the filter medium and accommodates the lower frame 103. The lower frame 103 and the upper frame 107 are joined by the convex portion 108 and the hole 109 to filter the filter. Was forming.

  Moreover, what surrounds the filter medium formed in the zigzag shape with the reinforcing material is known (for example, refer patent document 2).

  The air filter will be described below with reference to FIGS. 17 (a) and 17 (b).

  As shown in the figure, the front and side surfaces of the filter medium 201 are surrounded by a reinforcing material 202 made of a lath net, and the side surfaces are fixed by a sealing material 203.

  Moreover, what prevents the deformation | transformation of the filter medium formed in the zigzag shape is known (for example, refer patent document 3).

(Embodiment 1)
As shown in FIGS. 1 to 5, a nonwoven fabric made of synthetic fiber made of synthetic resin not containing chlorine is pleated and an adhesive (hot melt) 1 is applied to maintain a plurality of rows at the top of the mountain. When the filter medium 2 is surrounded by an L-shaped cross section so as to be provided over the side face 3 and the ventilation end face 4 of the filter medium 2 that is fixed, the ventilation end face 4 side corresponds to the corner of the filter medium 2 and is bent. A notch 6 is provided in a portion corresponding to the corner of the filter medium 2 on the side of the frame piece 5 to be formed so as to surround the four circumferences of the filter medium 2, and both ends are joined at the side surface 3 in the pleat folding direction of the filter medium 2. A frame body 7 is provided, and the side wall 8 of the frame body 7 is formed of polypropylene, polyethylene, ABS, or the like that does not contain chlorine so that the height of the side wall 8 is smaller than the thickness dimension of the filter medium 2, and is bonded to the four circumferences of the filter medium 2. And fix.

  Further, a seal member 9 formed of synthetic resin such as polyethylene, ester-based or ether-based urethane not containing chlorine is attached to the frame piece 5 provided on the side of the ventilation end surface 4 of the frame 7 to assemble the apparatus. The air filter 10 is configured to increase the degree of sealing.

  In the above configuration, as shown in FIG. 2, when the air filter 10 is incorporated in the air flow path of the air conditioner along with the mounting rail 25 together with the pre-filter 10a, the frame body 7 has higher strength than paper and has dimensional accuracy. Since the sealing member 9 is in close contact with the mounting portion of the air conditioner by the action of the wind pressure by the air blowing operation, air leakage from the air flow path is eliminated.

  Next, when dust accumulates on the air filter 10 and the air filter 10 needs to be replaced, the air filter 10 is pulled out from the mounting rail 25 and delivered to the waste fuel manufacturing factory as it is. It will be recycled to waste regenerated fuel.

  In this way, the production of waste fuel that is recycled into waste regenerated fuel refers to so-called RDF (waste solidified fuel) production, waste plastic oil production, etc., and is performed for waste power generation or waste heat treatment. RDF is made by collecting burning garbage, pulverizing it, drying it, adding additives and compressing it. The heat of RDF is about half that of coal, and combustion is stable. In addition, it does not rot, does not emit bad odor, can be stored, is easy to handle, has a higher combustion temperature than simple incineration, has almost no harmful substances such as dioxin when burned, and has many advantages Yes.

  In the first embodiment, the air filter 10 is unified with a synthetic resin not containing chlorine so that dioxins are not generated, and since paper and cloth are not included, maintenance management during combustion and storage as a homogeneous fuel is easy. It can be carried out.
