Abstract

PROBLEM TO BE SOLVED: To protect effectively a deodorizing plate layer while it is easily treated by a method wherein, as a deodorizing filter, the deodorizing filter with a frame composed of a frame body having an opening, a deodorizing plate layer which is stored in the frame body and ventilates from a front to a rear, and a filter medium which is in layers installed to the deodorizing plate layer is used. SOLUTION: A deodorizing filter with a frame has a frame body 1 wherein an opening through which air flows is provided, and it is made of synthetic resin material or the like. Ventilation is carried out through the holes passing from a front to a rear over all its surface, and a deodorizing plate layer 3 prepared in a platy shape with deodorant such as active carbon is stored in the frame body 1. When the deodorizing plate layer 3 is made of active carbon in this case, its side wall is preferably coated with a protective material 4 of nonwoven fabric, sponge, etc. Then, filter medium 5 of paper, nonwoven fabric, etc., is installed in layers to the deodorizing plate layer 3, and air is filtered by passing through the deodorizing plate layer 3 and the filter medium 5. Since both of the deodorizing plate layer 3 and the filter medium 5 are set to the frame body 1, the deodorizing filter with frame can simultaneously treat deodorizing and filtration.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a framed deodorizing filter having a deodorizing plate layer.

[0002]

2. Description of the Related Art There has been no framed deodorizing filter having a deodorizing plate layer.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and to provide a framed deodorizing filter having a deodorizing plate layer.

[0004]

According to the present invention, a frame having an opening, a deodorizing plate layer housed in the frame and ventilated on the front and back sides, and a deodorizing plate layer are mounted on the deodorizing plate layer to achieve the above object. The present invention proposes a framed deodorizing filter composed of a filter medium.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A framed deodorizing filter according to the present invention will be described below with reference to an embodiment shown in the drawings. 1 and 2 show a deodorizing filter with a frame of the present invention. The deodorizing filter with a frame has an opening (2) through which air flows, and has a frame (1) made of a synthetic resin material or the like. A deodorizing plate layer (3) made of a deodorizing material such as activated carbon and ventilated through a hole (small hole, not shown) penetrating the front and back over the entire surface is housed in the frame (1). . When the deodorizing plate layer (3) is made of activated carbon, it is brittle as a material, so that the side wall is made of non-woven fabric,
It is desirable to cover with a protective material (4) such as a sponge.
Next, a filter medium (5) such as paper or nonwoven fabric is superimposed on the deodorizing plate layer (3).
Is attached, and the air passes through both the deodorizing plate layer (3) and the filter medium (5). As shown in FIG. 2, the filter medium (5) is attached to the frame (1) at the end by bonding, welding, or the like. The operation of the framed deodorizing filter of the present invention shown in the above embodiment is as follows. That is, the deodorizing filter with a frame is a frame (1)
Since both the deodorizing plate layer (3) and the filter medium (5) are set in the filter, both deodorizing and filtering can be performed simultaneously.

[0006]

The embodiments of the frame-equipped deodorizing filter of the present invention are as described above, and the effects are listed below. (1) The frame-equipped deodorizing filter of the present invention is particularly easy to handle because the deodorizing plate layer is incorporated in the frame. (2) In the deodorizing filter with a frame of the present invention, the deodorizing plate layer is particularly protected because the filter medium is superposed on the deodorizing plate layer.
