臭気なども加熱することになる。For example, when heating a room with an electric stove, it not only heats the air in the room, but also heats up cigarette smoke and other indoor odors.
一般に、臭気というものは温度が高いほど、人間の鼻に
は強く感じるものである。このため電気ストーブを使用
すると、電気ストーブを使用しないときに比べて臭気が
きつくなるという課題が生じる。Generally, the higher the temperature, the stronger the odor is perceived by the human nose. For this reason, when an electric stove is used, a problem arises in that the odor is stronger than when the electric stove is not used.
このように、周囲に臭気や有害ガスが存在するときに、
電気発熱体で加熱を行うと、被加熱物を加熱することは
勿論であるが、臭気や有害ガスも同時に加熱してしまう
ために、かえって臭気がきつくなるという課題が生じる
。In this way, when there are odors or harmful gases in the surroundings,
When heating with an electric heating element, it goes without saying that the object to be heated is heated, but it also heats up odors and harmful gases at the same time, resulting in a problem that the odor becomes even stronger.
本発明は上記従来技術にもとづき、簡単な構成で、臭気
や有害ガスを除去する加熱装置を提供するものである。The present invention is based on the above-mentioned prior art and provides a heating device that has a simple configuration and removes odors and harmful gases.
課題を解決するための手段

また、電気発熱体を略直立し、電気発熱体に近接し、か
つ電気発熱体の周囲を多数の連通孔を有する筒状触媒で
田い、筒状触媒の開口部の一喘を閉塞する構成にする。In addition, the electric heating element is arranged approximately upright, close to the electric heating element, and surrounded by a cylindrical catalyst having a large number of communication holes, and a part of the opening of the cylindrical catalyst is closed.

気発熱体は電気発熱体近傍の空気も加熱するために、電
気発熱体近傍に自然対流として空気流が生じる。Since the cylindrical catalyst body having a large number of communication holes is provided close to the electric heating element, the electric heating element heats the object to be heated and also the catalyst body. Here, since the catalyst body surrounds the electric heating element, the temperature of the catalyst body is raised to the activation temperature of the catalyst in a short time in order to efficiently absorb the radiant heat emitted from the electric heating element. Furthermore, since the electric heating element also heats the air near the electric heating element, an air flow is generated near the electric heating element as a natural convection.
そして、この空気流が電気発熱体の加熱により触媒の活

５を発熱体の全周を覆うように設置する。EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings. In FIG. 1, a heating element section 1 is composed of a heating wire 2 and a quartz tube 3, and is insulated by an insulator 4. A cylindrical catalyst body 5 having a large number of communication holes is installed close to the heating element 1 so as to cover the entire circumference of the heating element.

利用できる。The catalyst body 5 is a plate-shaped body having a large number of communicating holes, and is suitably a ceramic honeycomb body, a foamed ceramic body, a braided body of heat-resistant fibers, a nonwoven fabric of heat-resistant fibers, or the like, in which the catalyst is supported. As the catalyst body 5, one that absorbs radiant heat well and has high thermal conductivity can easily raise the temperature, so that the activity of the catalyst can be effectively utilized.
特にセラミックハニカム体を用いる場合は、ハニカム体
表面の法線方向に対して傾斜角を持つ連通孔を穿つと、
ハニカム体表面での投影面積が増加し、発熱体１の輻射
熱の吸収特性が非常によくなる。Particularly when using a ceramic honeycomb body, if a communicating hole is formed at an angle of inclination to the normal direction of the honeycomb body surface,
The projected area on the surface of the honeycomb body increases, and the radiant heat absorption characteristics of the heating element 1 become very good.

うになり、触媒の活性温度まで短時間で昇温され、かつ
触媒体５の温度を高温にすることができる。When the heating element 1 is energized, heat rays are emitted from the heating element 1 in the entire circumferential direction of the heating element 1. However, the catalyst body 5 is the heating element 1
Since it is installed so as to cover the entire circumference of the heating element 1, all of the heat rays emitted in the circumferential direction of the heating element 1 are radiated onto the surface of the catalyst body 5, so that the catalyst body 5 is efficiently heated by radiation. As a result, the temperature can be raised to the activation temperature of the catalyst in a short time, and the temperature of the catalyst body 5 can be made high.
一方、発熱体１は発熱体１近傍の空気も加熱するために
発熱体近傍に自然対流として空気流６が生じる。そして

When this air flow 6 passes through the catalyst body 5 whose temperature has been raised to the activation temperature of the catalyst by the heating of the heating element 1, it is purified by the catalytic action and odor is removed.
したがって、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
され、快適な加熱環境をつくることができる。Therefore, even if harmful gases such as odor and cigarette smoke are present in the atmosphere in which the heating device is placed, they are purified during heating and a comfortable heating environment can be created.

媒の活性をより有効に活用することができる。Furthermore, as shown in FIGS. 2 and 3, when the heating element 1 is installed at an angle of inclination to the vertical direction, the air flow 6 generated by the heating of the heating element 1 passes through the communication hole of the catalyst body 5. As a result, the contact area between the air flow 6 and the catalyst body 5 increases, and the activity of the catalyst can be utilized more effectively.
