望まししＸ。An example of a conventional electric kotatsu will be described below with reference to the drawings. In FIG. 4, an upper heat reflecting plate 24 is provided on the lower surface of the top 23 of the tower 22, and the air inside the tower is below the heat reflecting plate 24. Even though a fan 25 that rotates at a constant rotational speed is provided, an electric heat generator is provided on the side where the air flow generated by the fan 25 is blown out so that the fan 25 is located approximately at the center. A body 26 is provided. As an example of the electric heating element 26, as shown in FIG. A heat shield plate 27 is provided below the electric heating element 26 to prevent exposure of the electric heating element 26 which becomes hot, and a lattice cover 28 is provided to cover the heat shield plate 27. Even if the heat shield plate 27 is provided so as not to be exposed, the electric heating element 2
A part of the heat generated from the electric heating element 26 heats the air supplied from the fan 25 and circulates inside the kotatsu as warm air, heating the inside of the kotatsu.At the same time, infrared rays are emitted from the electric heating element 26 in all directions. The radiation toward the top of the kotatsu comes from the upper reflector 24.
Although the kotatsu is structured so that it is reflected by the kotatsu and radiates it into the kotatsu for efficient heating, the problem that the invention aims to solve is that the conventional electric kotatsu has the following problems. As a result, the inside of the kotatsu becomes filled with the odor of human body odor, sweat, and especially the foul odor emitted from human feet.a This odor rides on the circulation flow generated by the fan and is heated by the electric heating element. In general, the higher the temperature, the stronger the odor is perceived by the human nose.Therefore, not only does the kotatsu heat the human body, but it also heats up the odor trapped inside the kotatsu, making it even more odorous. If you open the kotatsu futon in order to enter the kotatsu, the air inside the kotatsu will ride up the rising air and be released outside, making you feel uncomfortable.However, the present invention is based on the above-mentioned conventional technology and has a simple method. The present invention provides an electric kotatsu that removes odors from inside the kotatsu.Means for Solving the ProblemsThe electric kotatsu of the present invention sucks air from the top plate, the legs, and the bottom and discharges it in a substantially horizontal direction. A centrifugal fan, an electric heating element provided around the centrifugal fan, a heat reflecting plate provided above and below the electric heating element and between the electric heating element and the fan, and a heat reflecting plate provided below the electric heating element from below. In the configuration including a net-like or grid-like cover provided to cover the electric heating element, at least one surface of the electric heating element heat reflection plate has a porous coating layer containing a catalytic material, and is provided between the electric heating element and the fan. Function: The electric kotatsu of the present invention is characterized in that the heat reflecting plate provided with an opening is provided with a heating element and/or a heat reflecting plate surface ζ provided above and below the electric heating element and between the electric heating element and the fan.
d. The challenge is to provide a porous coating layer that supports a catalytic material.
When electricity is applied to the electric heating element, the electric heating element heats the object to be heated and also heats the porous coating layer through heat transfer and radiation, activating the catalyst substance supported on the porous coating layer in a short time. When the air containing components is heated by an electric heating element and comes into contact with a catalytic material that is also heated above the activation temperature, the catalytic action quickly purifies the air into 4 tons of acid and makes it odorless. The embodiment will be described based on the attached drawings. In FIG. 1, 1 is an electric heat generating plate, 2 is a fan, 3 is a fan heat reflector plate opening, 4 is an upper heat reflector plate, 5 is a fan heat reflector plate, 7 Sekiguchi A6 is the lower heat reflector, 9 Hayagura Ten K, 10 Hayagu 8 is the lattice cover, 11 is the fixing screw for the heating element unit consisting of the electric heating element, fan, heat reflection plate, etc. When the electric heating element 1 is energized, infrared rays are emitted from the electric heating element 1 in the entire circumferential direction of the electric heating element 1.The electric heating element 1 has a built-in electric resistor 12 as shown in FIG.
A quartz tube 14 filled with r gas 13 4 Electric heating element 1
Porous coating layer 15+1 containing a catalyst material formed on the surface
Since it is installed so as to cover the electric heating element I, the infrared rays emitted from the electric heating element I in the entire circumferential direction are radiated to the porous coating layer 15, and the porous coating layer 15 is rapidly heated. When the electric heating element 1 is energized, the fan 2 also starts, sucking the air inside the kotatsu below the fan and discharging the air from the fan heat reflection plate opening 3 in a substantially horizontal direction. The air inside the kotatsu is supplied to the electric heating element 1 provided around the fan 2. When the odor components in the air come into contact with the electric heating element 1, the odor components in the porous coating layer 15 provided on the surface of the electric heating element 1 Due to the catalytic oxidation action of the activated catalytic material, it is quickly oxidized and purified and released into the kotatsu as infinite air.In this configuration, however, the infrared rays radiated from the upper heat reflector plate 4c electric heating element are absorbed into the kotatsu. For safety, a temperature fuse may be installed in contact with the upper heat reflector plate 5. A fan is provided between the fan 2 and the electric heating element 1, and has an opening 3 for the purpose of preventing overheating due to heating of the electric heating element of the fan motor, so that airflow from the fan is supplied to the electric heating element 1. A porous coating layer formed on the surface of the electric heating element 1 to reflect infrared rays from the electric heating element 1 to the heating element, with consideration for safety to prevent exposure of the electric heating element 1 which becomes hot. This is because by maintaining the porous coating layer 15 at a high temperature, the activity of the catalytic material supported therein can be maintained. It is desirable to provide an opening 7 in the reflection plate 6.
This is because some of the infrared rays emitted from the porous coating layer 15 can heat the body of the person taking the warmth through the openings, allowing the user to feel a faster heating sensation. Various metals are used as the heat reflecting plate. For example, a stainless steel-containing aluminized steel plate, an aluminum clad steel plate, or an aluminum plate can be used to prevent the person's body from coming into direct contact with the lower heat reflecting plate 6, which heats up due to the heat of the electric resistor 1. However, in the present invention, a porous coating layer containing a catalytic material is provided to prevent this. The porous coating layer has a microscopically large surface area, and when the catalyst material is supported thereon, the catalyst material can be supported in a very highly dispersed manner. A coating layer having highly active catalytic ability can be obtained. In addition, when the coating layer is porous, air containing odor substances can easily diffuse within the coating layer, and this also contributes to smooth purification of odor components. Therefore, the porous coating layer of the present invention CL Unlike the coating layer formed using a resin binder or a glassy binder that does not provide a porous coating layer, the porous coating layer of the present invention is mainly made of an aluminum-9-silica precursor, for example, a hydroxide, Even if the coating layer is made porous by dehydration by firing and forming bonds, the specific surface area of the porous coating layer is 10[1]2/g or more. It is desirable to add alkaline earth rare earth elements to thermally stabilize the alumina, and to improve the radiation efficiency of far infrared rays that are emitted from the porous coating layer and provide a good heating effect.

なる。In the embodiment of the present invention shown in FIGS. 1 and 2, a porous coating layer 15 containing a catalyst material is formed on the surface of the electric heating element 1; As a result, the heat generated in the electrical resistor 1 is transferred to the foam used to directly heat the porous coating layer 15 in close contact with the resistor 1.
The porous coating layer 15 becomes hot in a short time. In order for the catalytic material to oxidize and purify odor components, it is necessary to heat the porous coating layer 15 to a temperature higher than its activation temperature. This means that the catalytic material contained in the coating layer also heats up in a short period of time. The hot air containing odor components sent by the Atsushi fan is quickly oxidized and purified and becomes odorless.In the above configuration, when the amount of electricity supplied to the electric heating element 1 is small, the catalytic material is Odor components that are maintained above the activation temperature can be purified.As described above, by forming the porous coating layer 15 containing the catalyst material on the surface of the electric heating element, the porous coating layer 15 can be purified very efficiently. The most desirable L% is that the coating layer can be activated at a high temperature.Also, if the amount of current to the electric heating element 1 is large, the temperature of the heat reflecting plate that receives the heat from the electric heating element 1 increases. By forming the porous coating layer on L, the catalytic material contained therein can be sufficiently activated and the odor components can be oxidized and purified.

In addition, a porous coating layer (on the entire surface of the electric heating element and the heat reflecting plate) can be used. It is not necessary to provide it, and it may be formed in a part of it if necessary. It is preferable to use an annular electrical resistor as shown in Figure 3.By installing the annular electrical resistor so as to surround the fan, it is possible to discharge air from the fan in almost all horizontal directions. This is because the air inside the kotatsu containing odor components can be supplied to the electric heating element most efficiently and evenly, and the air inside the kotatsu can be quickly deodorized. In Figure 3, 16.17 is a porous coating. M!, 18.19 is electric heat generation & 20.21 is a fan.As described above, according to the present invention, the odor inside the electric kotatsu can be removed by catalytic action. If you use the kotatsu for a long time, human sweat and body odor will not accumulate inside the kotatsu, providing a comfortable environment.
