大きくできないなどの難点がある。 As shown in Fig. 5, the deodorizing element e has been produced by alternately laminating nonwoven fabrics 11 made of thermoplastic synthetic fibers and granular activated carbon 12, and compacting them with a hot press to form a mat shape. and granular activated carbon 12 are partially heat welded, and the entire front and back surfaces are covered with nonwoven fabrics 13a and 1 of the same material.
3b and heat-sealing the overlapping portion 14 is generally known. (Refer to Utility Model Application No. 55-141535.) (Problems to be solved by the invention) By the way, in the conventional deodorizing element described above, the nonwoven fabric and the granular activated carbon are welded together, but only partially, and in the welded part, the granular activated carbon is flat. Since it is attached to the non-woven fabric only in point contact, the retention state is unstable and it is easy to peel off. Furthermore, since the layer between the non-woven fabrics has no partition and just spreads horizontally, the free activated carbon is susceptible to vibrations of the car body and It moves due to inclination and causes unevenness, which significantly reduces the deodorizing function.Also, activated carbon rubs against each other and wears out, causing secondary pollution, making it impossible to increase the packing density of granular activated carbon. There is a drawback.
そこで、この考案は粒状脱臭剤の保持状態が確

On the other hand, the peripheral edge and the bottom ends of the vertical and horizontal grooves 1a and 1b are thermally welded. The lower nonwoven fabric 4 and the inner nonwoven fabric 5 are each formed with a cross-shaped upward protrusion 6 (this may not be a cross but may have another shape extending in all directions) at a position corresponding to the center of the bottom of each small chamber 2 of the upper nonwoven fabric 1.

The particulate deodorizer 3 filled in the small chamber 2 is pressed against the upper nonwoven fabric 1.

される。 The deodorizing element e is formed approximately as follows. First, as shown in FIG. 3A, a hot press lower mold D 1 is provided with vertical and horizontal protrusions 1a' and 1b' corresponding to the grooves 1a and 1b of the upper nonwoven fabric in the recess, and the protrusions 1a mentioned above. The upper surface non-woven fabric 1 is
It is pressed and formed into a lattice-shaped dish shape having a large number of small chambers 2 as shown in Fig. 3 (B), and then the upper nonwoven fabric 1 is left on the lower mold D 1 and each small cell is formed as shown in Fig. 3 (C). 2 is filled with a predetermined amount of granular deodorizer 3,
The inner surface nonwoven fabric 5 for cushioning and the lower surface nonwoven fabric 4 are placed on top of each other, and in this state, an upper die D 3 for finishing is provided with a large number of protrusions 6' for forming ridges in the small chambers on the lower surface. Required temperature (about 130℃~200℃)
Heat and pressurize. As a result, the upper surface nonwoven fabric 1
The contact area between the lower and inner nonwoven fabrics 4 and 5, that is, the peripheral edge and the bottoms of the grooves 1a and 1b, are welded to each other, and the lower and inner nonwoven fabrics 4 and 5 have protrusions 6 that protrude into each small chamber 2. The granular deodorizing agent 3 formed and filled in each small chamber 2 is pressed against the upper surface nonwoven fabric 1 side while increasing its density, and the contact portion is welded to form an element e as shown in FIG.

気を浄化する。 The deodorizing element e formed in this way is used as it is or is housed in an appropriate case and installed at a position below the filter of the air purifying device, and is used to remove fine dust such as cotton dust. At the same time, it purifies the indoor air by absorbing various bad odors that accumulate indoors.

れは省略しても差支えない。 At that time, the granular deodorizer 3 is accommodated in the small chambers 2 that are divided and formed in the upper nonwoven fabric 1, and each of the small chambers 2
Because it is pressed against the upper nonwoven fabric 1 side by the protrusions 6 formed on the lower and inner nonwoven fabrics 4 and 5 that protrude into the inside, even if vibration or tilting is applied to the element e from the outside, granular deodorization will not occur. The agent 3 does not move or shift, and is maintained at an appropriate packing density in each small chamber 2, so that the deodorizing function will not deteriorate even after long-term use. In addition,
In the illustrated example, an inner nonwoven fabric 5 is used to better retain the granular deodorizing agent 3, but this may be omitted.
