03), the heater (101) has nut fastening portions (101a) at both ends so that the deodorizing member (102) can be coupled, and the deodorizing member (102) is shown in FIG. As shown in FIG. 3B), the handle has a handle, and the surface of the disk of the deodorizing member other than the screw fastening portion is covered with silicon (1
02c), adsorbent (102a), platinum catalyst (102b)
Is formed, and the shape of the deodorizing member is such that a protrusion is formed in the central portion of the deodorizing member in order to maintain a constant air flow interval.

The details of the method of manufacturing the deodorizing device and the deodorizing member configured as described above are as follows. First, an electric heating part (102) that transfers heat generated from the heater (101).
In (d), aluminum (Al) having a good heat transfer capability is used to form a shape having a handle as shown in FIG. 6 (A), and then the handle of the heating portion is held to provide excellent heat resistance. It is taken out after being immersed in a silicone solution of which viscosity is adjusted appropriately.

Next, the electric heating part impregnated with the silicon solution is put in a circular separator and rotated so that the impregnated silicon solution is evenly distributed on the surface of the electric heating part. After the above process, after the silicon film is hardened, the carbon powder is adhered onto the surface of the silicon film, and the platinum powder adheres to the adsorbent such as zeolite, silica, etc., and is evenly distributed on the silicon surface. , Put it in the oven to cure.

After being placed in an oven and cured, the deodorizing member can be manufactured by cutting and removing the handle portion of the cured deodorizing member. A plurality of deodorizing members (102) manufactured by the above process are incorporated in a heater (101), and a lead wire (104) which is an electric supply source for heat generation is connected to the heater (101), and both ends are connected.

The deodorizing principle of the deodorizing device of the present invention manufactured and attached by the above manufacturing method will be described below. As shown in FIG. 9, the air is generated by the rotation of the indoor fan (105).
It passes through the heat exchanger (106) and through the deodorizer (100).

In the air flowing into the deodorizing device (100), the adsorbent powder adsorbs the malodorous gas component, and only clean air is discharged into the room through the discharge port. , Gradually adsorbing malodorous gas,
The deodorizing efficiency decreases as shown in the graph of (A) in FIG. After the decrease in the adsorption efficiency is calculated by integrating the indoor malodorous gas concentration, the indoor fan operating time, etc., the heater is heated when the heater (101), which is a heat source, is energized based on the time when the adsorption efficiency reaches 90%. The surface of (101) gradually increases in temperature and is incorporated in the deodorizing member (1
The temperature of the electric heating part (102d) of 02) also rises with this.

When the temperature of the electric heating section rises and the surface temperature of the deodorizing member reaches about 250 ° C., the malodorous gas component adsorbed on the adsorbent is adsorbed on the adsorbent fine pores or around the adsorbent. It is completely oxidized to water (H ₂ O) and carbon dioxide (CO ₂ ) by the catalyst. In the complete oxidation process, the malodorous gas component is exchanged for completely odorless water and carbon dioxide, which is a typical odor of the indoor malodorous gas component and is the source of the rotten smell of Chinese cabbage. In the case of mercaptan (CH ₃ SH), it is completely decomposed into water and carbon dioxide according to the route as shown in formula (1).
