および燃焼量域の拡大を目的とする。Conventional technology Conventional heat generating devices are made by coiling metal wires such as nichrome wire or Kanthal wire, or by incorporating these into metal statues, quartz tubes, ceramic tubes, etc., or by incorporating electric resistors into ceramics. α Heat conduction Conventional catalytic combustion devices use honeycomb-shaped catalyst bodies.1.
X, this is preheated by an electric heater or a pilot burner to raise the temperature of the catalyst to the activation temperature.Combustion gas is supplied to the catalyst and it is combusted by catalytic action.The problem to be solved by the invention is as follows. Conventional heat generating devices have the following problems: For example, when heating with an electric stove,
It even heats the indoor air! Mi: Cigarette smoke floating in the room and indoor odors also heat up.A General? Q: The higher the temperature, the stronger the odor is perceived by the human nose.In other words, when there is an odor or harmful gas in the surrounding area, heating the object with the conventional heating device described above will cause the object to be heated to The problem is that the odor and harmful gases are heated at the same time, which makes the odor even stronger. The catalyst preheating section and the catalyst body are separated, and most of the heat generated from the preheating section is used to heat the catalyst body through indirect heat transfer from the gas flowing into the catalyst body. However, it is not possible to heat the catalyst efficiently, and the honeycomb-shaped ceramic base material with a large heat capacity that forms the catalyst coating layer must also be heated, requiring a long time for preheating, and the possibility of fuel combustion. Although there are problems such as a lower limit on the amount, the present invention aims to remove odors and harmful gases that are difficult to solve with the above conventional techniques, shorten the preheating time during catalyst combustion, and expand the combustion amount range. shall be.

成分が除去されて発熱装置から放出される。The catalyst coating layer formed on the surface of the tubular body that contains the working electrical resistor is heated to the activation temperature of the catalyst in a short period of time due to heat transfer and radiant heat from the electrical resistor. When heated by the resistor, E
Similarly, when it comes into contact with the catalyst coating layer heated above the activation temperature, it is quickly oxidized and purified by the catalytic action, odor components are removed, and it is released from the heat generating device.

焼させることができる。Furthermore, when a combustion gas consisting of fuel and combustion air is introduced into this heating device, it is indirectly preheated via the catalyst coating layer to the catalyst coating layer, which is heated directly to the activation temperature or higher by the electric resistor. When the combustion gas comes into contact with the fuel, the fuel burns quickly due to the catalytic action, and even though the preheating time can be greatly shortened, when there is little fuel to burn, in the conventional catalytic combustion device, the combustion heat generated by combustion is If the catalyst cannot be maintained above the activation temperature, the fire will be extinguished. The message is transmitted to the catalyst coating layer very efficiently.By applying a small amount of current to the electrical resistor, the catalyst coating layer can always be maintained above the activation temperature, making it easily stable even with a small amount of fuel. can be burned.

るからである。It is desirable that the walls of the box be coated or constructed with far-infrared radiating material. Most of the heat is emitted by convective heat transfer to the gas flowing inside the box, but by coating or configuring at least one wall of the box with a far-infrared radiating material, it can be released as infrared radiation useful for heating and cooking. This is because it can extract some of the heat.
When used for heating, the visual effect cannot be ignored. People's sense of warmth changes depending on the brightness; bright things give them a sense of warmth, while dark things give them the impression of being cold. If the box containing the tubular body is made of metal, the light from the electrical resistor will be blocked by the box, making the heating device dark and giving it a cold feel. On the other hand, by constructing one wall of the box with a glass body as a far-infrared radiating material, the light will not be blocked, and it will give a warm impression depending on the brightness of the surface. Mijikamaki: Instead of being transparent, the glass body may be colored in a warm color, such as red (°C.Also, by forming a plurality of tubular bodies having a catalyst coating layer or by having a curved shape, the area covered by the catalyst can be widened. This is because it is possible to improve the contact efficiency between the circulating gas and the catalyst coating layer.

6 is an air outlet 7 is a glass plate 8 is a box 9 is a safety fence a Although the catalyst coating layer 3 is composed of alumina with a large specific surface area and a platinum group catalyst, it also prevents the specific surface area from decreasing at high temperatures to the above alumina. It is desirable to add lanthanum oxide, cerium oxide, barium oxide, and it is also desirable to add silica to improve the adhesion to the tubular body, especially the quartz tube. By adding a metal oxide selected from the group consisting of cobalt oxide, titania, zirconia, magnesia, and chromium oxide, the far-infrared radiation efficiency can be further increased. Although it is possible to use a glass tube or the like, metal tubes have a large difference in thermal expansion with the catalyst coating layer. Although adhesion can be improved by using metal tubes with a metal oxide film formed on them, these tubular bodies have good thermal shock resistance, are easy to shape, and have sufficient adhesion with the catalyst coating layer. The shape of the tubular body 2 is not limited to a straight tube, and a curved tube may also be used. The wire is coiled and sealed in an air atmosphere, vacuum or rare gas, or when a metal tube is used, an electric resistor is sealed in the metal tube together with an insulating material.

The power exchanger that normally uses aluminum etc. The negative part is made of a far infrared radiating material such as the glass plate 7, so that the heat generated by the electric resistor and the heat generated by catalytic combustion can be absorbed by the heat exchanger.
Heating It is desirable because it can be converted into far infrared rays useful for cooking, etc. When the heater 5 is energized, heat rays are radiated from the heater 5 in the entire circumferential direction of the heater 5. Since the catalyst coating layer 3 is installed by covering the quartz tube 4 containing the heater 5, the heat rays emitted from the heater 5 in the entire circumferential direction are radiated to the catalyst coating layer 3. Heating and heat transfer heating are performed, and the catalyst coating layer 3 is heated to the active temperature in a short period of time, reaching a high temperature of 4. Then, this odor component force (contacts or diffuses in sequence to the four catalyst coating layers 3 heated to the activation temperature, and is quickly oxidized and purified by the catalytic action of the odor component force (air outlet 6

効率よく行えるためである。Furthermore, the heat generated by the heater 5 not only becomes odorless hot air and contributes to heating, but also radiates as far infrared rays via the glass plate 7 and radiantly heats the object facing the glass plate 7. Therefore, if there are odors such as cigarette smoke or harmful gases in the atmosphere where the heat generating device is placed, they will be purified during L heating to create a comfortable heating environment. The straight tubular bodies with a coating layer are arranged in a line so as to be substantially perpendicular to the air flow flowing inside the box body composed of the heat reflecting plate 8 and the glass plate 7.
This is because the air flow repeatedly collides with the tubular body, creating a turbulent flow, which is sufficiently agitated and allows the odor components to contact and purify the catalyst coating layer efficiently.

、予熱時間も非常に短縮された触媒燃焼装置が得られもFurthermore, when a combustion gas consisting of fuel and combustion air is introduced by the fan 2 into the catalyst coating layer 3 which has been directly heated above the activation temperature by the heater 5, the fuel is quickly combusted by the catalytic action of the catalyst coating layer 3. . Catalyst coating layer 3 (
It is formed in close contact with the quartz tube 4 that houses the heater 5 in a thin layer.It has a small heat capacity, and the heat is transferred smoothly from the heater 5 to the catalyst coating layer 3 by heat transfer and radiation. The preheating time, which has traditionally been a problem for salts heated to activation temperatures, can be greatly reduced. In addition, when there is little fuel to burn, the power (heater 5
By supplying a small amount of electricity to the catalyst coating layer 3, it is possible to maintain the catalyst coating layer 3 at a temperature higher than the activation temperature at all times, and it is possible to easily and stably burn even a small amount of fuel. Even though it is provided to prevent the object to be heated from coming into direct contact with the glass body 7, the present invention has more than the effects of the invention. The gas line is purified by the catalytic action, which makes it difficult to use a heating device.It can provide a comfortable heating environment.Furthermore, even a small amount of fuel can be easily and stably combusted, and the preheating time is A very shortened catalytic combustion device can also be obtained.
