The heat of the heater is heated by conduction, convection, or radiation by forcibly sending air from the fan to the heat source to generate hot air, or by installing a reflector behind the heat source to perform radiant heating. Is going.
発明が解決しようとする課題 このような従来の加熱処理装置には、以下に示すような
課題があった。Problems to be Solved by the Invention Such a conventional heat treatment apparatus has the following problems.
たとえば電気ストーブで暖房する場合、室内の空気を加
熱するとともに、室内に漂っているタバコの煙や室内の
臭気なども加熱することになる。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

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。For example, in the case of heating with an electric stove, indoor air is heated, and at the same time, smoke of cigarettes floating in the room and indoor odor are also heated. Generally, the higher the temperature, the more the odor is felt by the human nose. Therefore, when the electric stove is used, there is a problem that the odor becomes more intense 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 is odor or harmful gas in the surroundings,
When the heating is performed by the electric heating element, it goes without saying that the object to be heated is heated, but since the odor and the harmful gas are also heated at the same time, there is a problem that the odor becomes rather severe.
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 for removing odors and harmful gases with a simple configuration.
課題を解決するための手段 電気発熱体と、多数の連通孔を有する担体に触媒を担持
した筒状触媒体を有し、電気発熱体近傍に空間を設け、
筒状発熱体で電気発熱体の周囲を覆う構成にする。Means for Solving the Problems An electric heating element and a tubular catalyst element carrying a catalyst on a carrier having a large number of communication holes, and a space is provided near the electric heating element.
A cylindrical heating element covers the periphery of the electric heating element.
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
覆い、筒状触媒の開口部の一端を閉塞する構成にする。In addition, the electric heating element is substantially upright, close to the electric heating element, and the periphery of the electric heating element is covered with a cylindrical catalyst having a large number of communication holes, and one end of the opening of the cylindrical catalyst is closed. .
作用 この技術的手段による作用は次のようになる。Action The action of this technical means is as follows.
電気発熱体に近接して多数の連通孔を有する筒状の触媒
体を設けてあるために、電気発熱体は被加熱物を加熱す
るとともに、触媒体も加熱することになる。ここで触媒
体は電気発熱体の周囲を覆っているために、電気発熱体

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。そし
て、この空気流が電気発熱体の加熱により触媒の活性温
度まで昇温された触媒を通過する際に、触媒作用により
浄化され、臭気が除去されて加熱装置から放出される。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 heats the catalytic element. Here, since the catalyst body covers the periphery of the electric heating element, the catalyst body is heated 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 in the vicinity of the electric heating element, an air flow is generated as natural convection near the electric heating element. Then, when this air flow passes through the catalyst whose temperature has been raised to the activation temperature of the catalyst by heating the electric heating element, it is purified by the catalytic action, odors are removed, and the air is discharged from the heating device.
上記作用は電気発熱体近傍に生じる自然対流について説
明したが、触媒体にファンなどで強制的に空気を供給し
た場合でも同様な効果がある。The above operation has been described with respect to natural convection that occurs in the vicinity of the electric heating element.
実施例 以下、本発明の一実施例を添付図面に基づいて説明す

により構成され、碍子４により絶縁されている。そして
発熱体１に近接して、多数の連通孔を有する筒状の触媒
体５を発熱体の全周を覆うように設置する。Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, a heating element portion 1 is a heating wire 2 and a quartz tube 3.
And is insulated by the insulator 4. Then, in the vicinity of the heating element 1, a cylindrical catalyst body 5 having a large number of communication holes is installed so as to cover the entire circumference of the heating element.

は、白金、パラジウム、ロジウムなどの白金族である。
触媒体５としては輻射熱をよく吸収し、熱伝導率の高い
ものが昇温しやすく、触媒の活性を有効に利用できる。
特にセラミックハニカム体を用いる場合は、ハニカム体
に穿いてある連通孔を斜めに穿つと、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
常に良くなる。The catalyst body 5 includes a platinum group metal and nickel on a plate-shaped carrier having a large number of communicating holes such as a ceramic honeycomb body, a foamed ceramic body, a braided body of heat resistant fibers, and a nonwoven fabric of heat resistant fibers.
It carries an oxidation catalyst for metal oxides such as cobalt, iron, manganese, and chromium. Sometimes preferred as catalysts are platinum groups such as platinum, palladium, rhodium.
The catalyst body 5 that absorbs radiant heat well and has a high thermal conductivity is likely to be heated, and the activity of the catalyst can be effectively utilized.
Particularly when a ceramic honeycomb body is used, if the communication holes formed in the honeycomb body are formed obliquely, the projected area on the surface of the honeycomb body increases, and the radiation heat absorption characteristics of the heat generating element 1 become very good.
発熱体１に通電すると、発熱体１から熱線が発熱体１の
全周方向に放射される。ところが、触媒体５は発熱体１

周方向に放射された熱線が触媒体５表面にすべて放射さ
れるために、触媒体５の輻射加熱が効率よく行われるよ
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の温度を高温することができる。When the heating element 1 is energized, heat rays are radiated 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 the heat rays radiated in the entire circumferential direction of the heating element 1 are radiated to the surface of the catalytic element 5, so that the catalytic element 5 is efficiently radiatively heated. 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 raised.
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、この空気流６が発熱体１の加熱により触媒の活性温
度まで昇温された触媒体５を通過する際に、触媒作用に
より浄化され、臭気が除去される。On the other hand, since the heating element 1 also heats the air in the vicinity of the heating element 1, an air flow 6 is generated as natural convection near the heating element. Then, 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 the 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 a harmful gas such as odor or cigarette smoke drifts in the atmosphere in which the heating device is placed, it can be 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。Further, as shown in FIG. 2 and FIG. 3, when the heating element 1 is installed so as to have an inclination angle with the vertical direction, the air flow 6 generated by heating the heating element 1 passes through the communication hole of the catalyst element 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.

As shown in FIGS. 5 and 5, when one end of the tubular catalyst body 5 is closed by the partition plate 7, the air flow 6 generated by heating the heating element 1 passes through the communication hole of the catalyst body 5. Therefore, 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.
また、第６図や第７図に示すように、発熱体１の少なく
とも半周を接触体5a、5bで覆っても同様な効果が得られ
る。Further, as shown in FIG. 6 and FIG. 7, the same effect can be obtained by covering at least a half circumference of the heating element 1 with the contact elements 5a and 5b.
これまでの実施例は電気発熱体近傍に生じる自然対流に
ついて説明したが、接触体にファンなどで強制的に空気
