As shown in the side cross-sectional view of the electric kotatsu in Figure 5, a reflecting plate 3 is provided below the top 2 of the tower 1 in a substantially planar shape, and below the reflecting plate 3 is a ring-shaped or straight pipe-shaped heat generating device. A body 4 is provided. As an example of this heating element 4, as shown in FIG. There is a heater equipped with a tungsten filament 8 that serves as a heat source. Reference numeral 6 denotes a heat shield plate having a large number of openings to adjust the heat radiation from the heating element 4, and is disposed to cover the lower part of the heating element 4.

のであった。Problems to be Solved by the Invention By the way, when heating with an electric kotatsu as described above, the tower 1 is covered with a heat insulating material such as a futon.
Because the inside of the tower is an airtight space, it was sometimes filled with the foul odor emanating from the feet of the people taking the heat. In such a case, the person taking the heat may inhale the bad odor that flows out from the gaps in the heat insulating material, causing discomfort.

しながら、前記の電気こたつの発熱体ユニｙ）では、そ
のやぐら内において自然対流が発生しにくいために、は
とんどその脱臭効果が得られないのである。Therefore, it is conceivable to form a catalyst layer supporting a platinum group metal catalyst on the surface of the heating element 4 to obtain the effect of deodorizing the bad odor by the catalyst activated by the heating element. However, with the above-mentioned electric kotatsu heating element unit y), natural convection is difficult to occur within the tower, so the deodorizing effect cannot be obtained at all.
課題を解決するだめの手段
そこで、この発明は前記の脱臭効果を高めるために以下

した構成としている。Means for Solving the Problems Therefore, the present invention has the following configuration in order to enhance the deodorizing effect described above. That is, a protrusion having a side inclined surface that slopes downward and inward is formed on the lower surface of the reflector, and a platinum group metal catalyst is supported on the outer periphery on the side and below the side inclined surface of the protrusion. The structure includes a heating element with a catalyst layer formed thereon.

As a result, new air flows into the vicinity of the heating element, creating natural convection within the tower. Since the heating element is placed on the side of the protrusion, where the flow rate of this convection is large and the flow velocity is high, and below the sloped side of the protrusion, bad odors inside the tower are absorbed by the catalyst layer activated by the heating element. It can deodorize efficiently.

This inverted truncated conical protrusion has an arcuate side inclined surface whose cross section is convex upward from the flat surface of the reflecting plate 9 toward the bottom and inward of the center. An annular heating element 4 as shown in FIG. 2 is disposed on the side of the side inclined surface of this protrusion and below it. Furthermore, the heat dissipating plate 10, which is provided so as to cover the entire lower surface of the reflecting plate 9 and the heating element 4, is provided with a large number of opening holes for adjusting the amount of heat of the heating element 4, and A vent hole 14 is formed below the body 4, and a wind guide plate 12 is formed on the side of the vent hole 14. Note that 6 is a protective guard.

As shown in FIG. 2, this is formed on the entire surface of the heating element 4 except for the sealing part 13. This catalyst layer 11 is made of a far-infrared emitting porous material made of at least one oxide among oxides such as aluminum oxide, silicic acid, cerium oxide, zirconium oxide, and titanium dioxide, and a platinum group metal catalyst such as platinum and palladium. It carries the following. Note that the method for forming the catalyst layer 11 is as follows:
A heating element 4 in which a far-infrared ray emitting porous body is formed in advance on the outer periphery.
In this method, a slurry containing a platinum group metal catalyst is applied,
It is best to bake it after attaching it by the printing method or printing method.

効率よく脱臭することができる。Next, the operation of the electric kotatsu constructed as described above will be explained. When the air around it is warmed by the heating element 4, the air whose specific gravity has become lighter rises along the side inclined surface of the protrusion and further reaches the flat surface of the reflector e, as shown in FIG. Air flow S moving outwards
As a result, new air flows into the heat shield plate 1o.
The air flows along the guide plate 12 provided in the air, passes through the ventilation hole 14, and natural convection occurs. Now, the heating element 40
The platinum group metal catalyst of the catalyst layer 11 formed on the surface is 1
When heated above 0, it is activated and increases the oxygen concentration in the vicinity.Therefore, when the air flow S passes near the highly activated catalyst layer 11, its malodorous components are fermented and decomposed. It is deodorized by changing into carbon dioxide gas and water.By the way, the heating element 4 is located in a space where the air flow S has the highest flow rate and the highest flow velocity, that is, on the side of the downward protrusion,
Moreover, since it is disposed below the side inclined surface, bad odors inside the tower can be efficiently deodorized by the catalyst layer activated by the heating element.

ある。Furthermore, the far-infrared emitting porous material of the catalyst layer 11 has an average spectral emissivity higher than that of quartz in the spectral wavelength range of 3 μm or more. That is, since the secondary thermal radiation energy of the far-infrared emitting porous body is larger than that from the surface of the quartz tube 7, the thermal radiation energy is much larger in the spectral wavelength range of 3 to 26 μm, which is the heat absorption band of the human body and clothing. You can get more. Furthermore, when the light generated by the light emitted from the tungsten filament 8 disposed inside the heating element 4 passes through the quartz tube 7 and is radiated into the tower, this far-infrared emitting porous body suppresses glare and , warm color light containing a large amount of red can be obtained.

Ｉｌｆｉ以上確保しなければならない。By the way, in order to improve the deodorizing characteristics, it is necessary to increase the temperature of the catalyst layer 11 to further activate the catalyst. Therefore, in this embodiment, the heating element 4 is arranged in a position as shown in FIG. 4 in detail. That is, in the reflecting plate 9, an inclined surface provided at the boundary between the protruding part and a flat part on the outside of the protruding part is R, the angle of the curvature surface forming the inclined surface R is θ, and the angle is When the center line of θ is P, the heating element 4 is located on the center line P, the distance between the inclined surface R and the heating element 4 is at least 6 degrees, and within the radius of curvature of the inclined surface H. It is located in If arranged in such a position, the heating element 4
The heat radiation from is reflected by the inclined surface R, and the heat radiation caused by this reflection heats the catalyst layer 11 formed on the surface of the heating element 4 again. It can be activated. However, the catalyst layer 11
can be used up to a maximum of 500''C, but the reflector plate 9 is often a steel plate with surface treatment such as galvanization and metal coating, and the normal heat resistance temperature is about 250''C. In order to keep the temperature of the reflecting plate below 260"C, the spatial distance between the heating element 4 and the slope R should be j)
You must secure at least Ilfi.

It is formed only on the surface of the kotatsu, but when using the kotatsu, the
If the catalyst layer 11 is also formed on the surfaces of the heat shield plate 10 and the reflector plate 9, which have a temperature of C or more, the deodorizing properties will be improved, and the far-infrared radiation energy in the spectral wavelength region of 3 to 25 μm will also be increased. However, when forming the catalyst layer 11 on the heat shield plate 10,
Since the temperature of the catalyst layer 11 on the surface of the heat generating element 4 can be further increased by utilizing reflection on the surface of the heat shield plate 1o facing the heating element 4, the catalyst layer 11 is formed only on the surface opposite to the heating element 4. do it. In addition, when forming the catalyst layer 11 on the reflection plate 9, a slope R1 that can raise the temperature of the catalyst layer 11 using reflection, and a slope surface that has a large friction against the air flow S are used. It is preferable not to form it on the side surface of the protrusion of the reflecting plate 9, which may inhibit natural convection, but to form it on the horizontal surface outside the protrusion.

A straight pipe-shaped heating element may be disposed on the side of the side inclined surface and below the side inclined surface.

The following effects can be obtained by disposing a heating element below which a catalyst layer in which a platinum group metal catalyst is supported is formed on the outer periphery of the heating element.

Since this heating element is disposed on the side of the protrusion where the air flow rate is large and the airflow velocity is high, and below the side slope, the catalyst layer activated by the heating element is heated. It can efficiently deodorize the odors inside the tower.
Comfortable heating can be achieved.
