構成したものである。2. Description of the Related Art A deodorizing device using a catalyst is used for deodorizing an odorous component in a refrigerator, a freezer or an office, and a catalyst is provided in a passage of air containing the odorous component (referred to as treated air). Is disposed, and the deodorizing component that comes into contact with the catalyst body is decomposed and removed by the catalytic action.

しい働きをするようになる。It is known that in such a deodorizing device, the catalytic action depends on the temperature of the catalytic body, and the higher the temperature, the greater the catalytic action. That is, the catalytic body becomes more activated in the function of the catalyst as the temperature becomes higher than that in the normal temperature state, and acts to promote the decomposition of the odorous component, which is preferable when used in the deodorizing device. Come to work.

A configuration is considered in which the temperature of the catalyst body 2 is raised by heating the catalyst body 2 to about 180 to 200 ° C. by the generated heat. Air to be treated 1 for the catalyst body 2
Are provided with a large number of fine holes 2a.
For example, as the catalyst body 2, SiO 2 , MnO 2 , T
A honeycomb-shaped plate-shaped member formed by mixing and sintering oxides such as iO 2 is used.

置される。FIG. 1 is a perspective view showing a first embodiment of the deodorizing apparatus of the present invention. The deodorizing device 10 of the present embodiment is arranged in the vicinity of or in contact with the catalyst body 2 in the shape of a rectangular parallelepiped whose length direction is arranged so as to be orthogonal to the traveling direction of the air to be treated 1 and the windward side of this catalyst body 2. For example, a honeycomb PTC heater 6 having a large number of through holes is provided. The catalyst body 2 has a large number of through holes 5 that function as flow paths for the air to be treated 1. The honeycomb-shaped PTC heater 6 has a rectangular parallelepiped shape having a width W, and has a large number of through holes 7 defined therein by the heater member 6A in the vertical and horizontal directions.
In FIG. 1, in order to understand the explanation, the catalyst body 2 and the honeycomb-shaped PT are used.
Although the C heater 6 is shown as being separated from each other, the two are actually arranged close to each other or in close contact with each other as shown in FIG.

面には電極８が形成されて電源４へ接続されている。The honeycomb-shaped PTC heater 6 is made of barium titanate-based ceramics, for example, and has a positive temperature characteristic as shown in FIG. Since the resistance value of the honeycomb-shaped PTC heater 6 can be changed by changing the composition ratio or the value of the width W, the temperature characteristics can be arbitrarily controlled. Particularly, the PTC heater has an advantage that the temperature rises quickly after energization. Electrodes 8 are formed on the side surface and the back surface of the honeycomb PTC heater 6 and connected to the power supply 4.

体にわたって均一に加熱されている。When the honeycomb-shaped PTC heater 6 is energized by the power source 4 through the electrode 8 in advance, the entire temperature including the heater member 6 generates heat and the ambient temperature rises to about 1
It is heated to 80 to 200 ° C. As a result, the catalyst body 2 adjacent to the honeycomb-shaped PTC heater 6 is heated by its heat, and the through-holes 7 are provided in the honeycomb-shaped PTC heater 6 so as to correspond to the through-holes 5. Fine heating is performed so that the catalyst body 2 is uniformly heated throughout.

うことができる。That is, while the honeycomb-shaped PTC heater 6 is made to generate heat in advance and the heat generated around each through hole 7 is sent to each through hole 5 to uniformly heat the entire catalyst body 2, Since the treated air 1 is introduced into each through hole 5, the temperature of the catalyst body 2 is uniformly increased because the catalyst body 2 is uniformly heated, so that its catalytic action is increased. Therefore, the odorous components can be efficiently deodorized.

で安定な加熱源として用いることができる。In particular, according to the present embodiment, since the honeycomb PTC heater 6 is used as a means for heating the catalyst body 2, it is possible to instantaneously perform deodorization by utilizing the speed of rise of the temperature of the PTC heater. You can Further, since the PTC heater does not generate abnormal heat as compared with a general metal heater, it can be used as a stable heating source.
