And a catalyst material such as an alumina-supported platinum group metal together with a suitable binder such as aluminum hydroxide, alumina sol, silica sol and the like. Of these, it is desirable to use an alumina-supported platinum group metal as a catalyst substance from the viewpoints of heat resistance and poisoning resistance. Further, it is desirable to add lanthanum oxide, cerium oxide and barium oxide in order to prevent the catalytic activity of the above alumina from being lowered at high temperatures. Furthermore, it is desirable to add a metal oxide selected from the group consisting of nickel oxide, iron oxide, cobalt oxide, titania, zirconia, magnesia, and chromium oxide to the catalyst coating layer 1 because the infrared radiation efficiency can be further enhanced.

温となる。When the electric heating element 3 is energized, infrared rays are emitted from the electric heating element 3. Here, since the catalyst coating layer 1 is installed by covering the tubular insulator 2 containing the electric heating element 3,
The catalyst coating layer 1 is heated by heat transfer from the electric heating element 3 and infrared rays emitted, partly as indirect heating via the tubular insulator 2 and partly by infrared rays passing through the tubular insulator 2. The infrared rays radiated from the electric heating element 3 passing through the catalyst coating layer by the heat reflecting plate 4 installed in the rear and the secondary infrared rays radiating from the catalyst coating layer 1 are reflected by the heat reflecting plate 4 and again. To heat the catalyst coating layer 1,
The catalyst coating layer 1 is heated to the activation temperature in a short time and becomes high temperature.
また、触媒被覆層１と熱反射板４との間に赤外線放射
と反射が繰り返され、他への放熱が少なくなる保温効果
のため、その間の空間が高温域となる。Further, infrared radiation and reflection are repeated between the catalyst coating layer 1 and the heat reflection plate 4, and the space between them becomes a high temperature region due to the heat retention effect of reducing heat radiation to the other.
一方、電気発熱体３はその近傍の空気も加熱するため

かに酸化浄化され、臭気が除去される。On the other hand, since the electric heating element 3 also heats the air in the vicinity thereof, an air flow is generated as a natural convection in the vicinity thereof. And
This air flow is heated in a high temperature region between the catalyst coating layer 1 and the heat reflection plate 4, and is brought into contact with the catalyst coating layer 1 heated to the activation temperature, so that the catalyst action promptly Oxidized and purified to remove odor.
従って、加熱装置が置かれている雰囲気に臭気やタバ
コの煙等の有害ガスが漂っていても、加熱の際に浄化さ

Reference numeral 7 is an electric heating element, 8 and 9 are heat reflecting plates, 9a is a through hole provided in the heat reflecting plate 9, 10 is a blower, 11 is a net lid for a heating device, and 12
Is an air intake, and 13 is a skeleton of the heating device.

８、９と触媒被覆層５間の保温効果により、低消費電力
の通電時にも触媒被覆層５を活性化温度まで加熱でき、
前記触媒被覆層による浄化作用を得ることができる。By installing the heat reflecting plates 8 and 9 on both sides of the tubular insulator 6 containing the electric heating element 7, heating from both sides by these heat reflecting plates 8 and 9 heats up to the activation temperature of the catalyst coating layer 5. However, the odor components and harmful components in the air are purified in a short time. Further, due to the heat retaining effect between the heat reflection plates 8 and 9 and the catalyst coating layer 5, the catalyst coating layer 5 can be heated to the activation temperature even when energizing with low power consumption,
It is possible to obtain the purifying action by the catalyst coating layer.

きる。Further, it is desirable that a plurality of through holes 9a be provided in the heat reflecting plate 9 of the previous example facing the object to be heated among the heat reflecting plates 8 and 9. Thus, when the through hole 9a is not provided, the heat generated by energizing the electric heating element 7 is discharged from the heating device as high temperature air mainly by convective heat transfer. Therefore, the heating device simultaneously heats not only the object to be heated but also the surrounding objects. Therefore, it is not efficient from the viewpoint of heating the object to be heated. On the other hand, by providing the through hole 9a in the heat reflecting plate 9 installed between the tubular insulator 6 containing the electric heating element 7 and the object to be heated, infrared rays emitted from the electric heating element 7 or tubular shape A part of the secondary infrared rays emitted from the catalyst coating layer 5 provided on the surface of the insulator 6 is directly emitted to the object to be heated through the through hole 9a. Therefore, the object to be heated is not only indirectly heated by the heated air but also directly heated by the radiant infrared rays, so that the object to be heated can be more effectively heated, and the object to be heated becomes a human being. From this point of view, warmth can be felt in a shorter time, and a desired result can be obtained.

らである。Further, it is desirable to provide a blower 10 as shown in FIG. This is to increase the contact amount of air to the activated catalyst coating layer 5 by sucking atmospheric air with the blower 10 from the air intake port 12 and forcibly supplying this air to the catalyst coating layer 5. This is because odorous components and harmful components in the air can be purified more quickly.

ルギー量が約15％増加した。Further, it is desirable to form an infrared radiation coating layer on the heat reflection plate 9 on the front side of the tubular insulator 6 facing the object to be heated. As a result, the heat reflecting plate 9 facing the object to be heated in FIG. 2 receives most of the infrared rays emitted by the energization of the electric heating element 7 and the secondary infrared rays emitted from the heated catalyst coating layer 5. Although it is reflected, part of it is absorbed and becomes high temperature. Therefore, by forming the infrared radiation coating layer on the heat reflecting plate 9 facing the object to be heated, the heat energy absorbed by the heat reflecting plate 9 is radiated again as infrared rays to increase the amount of radiant heat energy to the object to be heated. be able to. When the infrared radiation coating layer was formed on the heat reflection plate 7, the amount of radiant heat energy of the heating device was increased by about 15% as compared with the case where the infrared radiation coating layer was not formed.

ができる。The tubular insulator 6 is preferably installed so as to surround the blower 10. As a result, as shown in FIG. 2, the air taken in by the blower 10 from the front or the rear is
It is supplied in all two-dimensional lateral directions. By installing the tubular insulator 6 containing the electric heating element so as to surround the blower 10, the blow-through caused by the contact between the catalyst coating layer 5 formed on the surface of the tubular insulator 6 and the supply air is reduced. Therefore, the catalyst coating layer 5 and the air are efficiently contacted with each other, and the odor and harmful components in the air can be purified in a shorter time.

り、第３図（ａ）に示すように前記管状絶縁体６をリン
グ状とすることが望ましい。As shown in FIG. 3 (b), a straight tubular tubular insulator 6
Although the above-described quick cleaning action can be obtained by installing the blower 10 so as to surround the blower 10 by using the above book, in view of the complexity of the electric heating element control mechanism and the production cost, FIG. As shown, the tubular insulator 6 is preferably ring-shaped.
