Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Example 1)
FIG. 1 is a partially cutaway perspective view showing a radiant heating device according to a first embodiment of the present invention.

In FIG. 1, reference numeral 21 denotes a radiator which is heated to generate radiant heat, 22 denotes a heater disposed on the back surface of the radiator 21 to heat the radiator 21, and 23 denotes a radiator provided below the radiator 21. In order to irradiate the radiating surface of the surface, the light source is constituted by an LED or the like. Reference numeral 24 denotes a reflector provided on a substantially half circumference on the opposite side of the light source 23 from which the radiator 21 is irradiated.

Next, the operation and operation will be described. When the operation is started, the heater 22 and the light source 23 are energized. The radiator 21 is heated to about 200 to 400 ° C. by the heater 22 and emits radiant energy mainly composed of far-infrared rays for heating. At the same time, the light source 23 is turned on to irradiate the radiator 21 to indicate that it is in a heated state.

(4) In this type of radiant heating device, since the temperature of the radiator 21 is in the far-infrared ray generation region, it is difficult to obtain a visual heating effect such as an electric stove that uses a heater in a red heat state. In addition, it is difficult to visually determine whether the device is in a heated state or a non-heated state, and there is a danger of touching and causing burns, etc., and measures such as installing a protective guard on the entire surface of the radiator 21 are taken. ing. However, a part of the radiant energy radiated from the radiator 21 is blocked by the protective guard, and the energy that can be actually used as radiant heating decreases.

According to the configuration of the present invention, it is possible to display that the radiation surface is in a heated state by irradiating the radiation surface of the radiator 21 with the light source 23 while energizing the heater 22 to heat the radiator 21. Thus, the visual heating effect can be obtained together with the heating effect by the radiant energy generated from the radiator 21. In addition, it is possible to avoid unsafe acts such as tentacles, and it is possible to suppress a decrease in the heating effect due to shielding of radiant energy due to simplification of the protective guard.

Next, by using a cold cathode fluorescent tube as the light source 23, the life time of the light source 23 can be extended, and the frequency of failure can be reduced. That is, the cold cathode fluorescent tube can be lit without preheating the filament as compared with a general fluorescent tube, and has a longer lifetime because it has fewer high-temperature portions than a filament heat source. Further, since the light source 23 is disposed near the radiator 21 having a relatively high temperature and receives heat from the radiator 21, the temperature of the light source 23 rises. However, the use of cold cathode fluorescent tubes reduces the frequency of these failures, and if the usage time is long, such as a heating device, it can be used for a long time without any obstacles such as failures. Become.

In addition, by providing the reflector 24 over a substantially half circumference on the side opposite to the side of the light source 23 that irradiates the radiator 21, the amount of light generated from the light source 23 is reflected by the reflector 24 toward the radiator 21. The amount of light to be radiated can be increased, the radiant surface can be illuminated more brightly, and the fact that the radiator is in a heated state can be more clearly displayed. In addition, by blocking the light emitted from the light source 23 directly to the front side of the device, the light source 23 can be prevented from being glazed and the irradiation effect of the radiator 21 can be enhanced.

Next, the control unit (not shown) for controlling the input to the light source 23 changes the frequency of the power supplied to the light source 23 at a constant cycle, so that the amount of light generated from the light source 23 changes. The change in the brightness of the radiator 21 illuminated by the light source 23 whose light amount changes stimulates the sight and clearly indicates to the user that the radiator 21 is in a heated state.

{Circle around (2)} The same effect can be exhibited by repeating the supply and stop of the power supplied to the light source 23 at a constant cycle.

Next, the light source 23 is colored, or a colored filter or the like is attached, and the radiator 21 to be irradiated can be visually expressed in a warm color by warming the light to a warm color such as red or orange. It becomes possible to provide a comfortable heating effect by a visual heating effect together with a heating effect by far infrared rays generated by heating the radiator 21.

(Example 2)
FIG. 2 is a perspective view of a main part of a radiant heating device according to Embodiment 2 of the present invention.

The second embodiment is different from the first embodiment in that light sources 23a and 23b having different light colors are provided.

の も の Note that components having the same reference numerals as those in the first embodiment have the same structure, and a description thereof will be omitted.

Next, the operation and action will be described. When the power outlet of the apparatus is turned on, the light source 23a colored in a cool color such as blue or green is turned on to illuminate the radiator 21 and express the cool color.

Next, when the operation is started, the heater 22 is energized, and the radiator 21 is heated to about 200 to 400 ° C. by the heater 22 to emit radiant energy mainly composed of far-infrared rays for heating. At the same time, the light source 23a is turned off by a control unit (not shown) that controls the light sources 23a and 23b, and the light source 23b colored in a warm color such as red or orange is turned on instead, and the heated radiator 23 is irradiated to emit a warm color. To express visually warm.

When the device is in operation, the radiator 21 is heated to provide a comfortable heating effect by the visual heating effect together with the heating effect by the far-infrared ray generated and expresses that the radiator 23 is in a heated state. And unsafe acts such as tentacles can be prevented. In addition, when the operation is stopped, the radiator 21 is displayed in a cool color, so that the radiator 21 can be used as an interior of a room to be used, and can be used even when heating is unnecessary.

Next, during operation of the apparatus, a control unit (not shown) for changing the amount of power to the light source 23 and the frequency in accordance with the amount of power to the heater 22 is provided so that the amount of power to the heater 22 is large. When the radiation amount of the radiation energy from the body 21 is large, the amount of light generated from the light source 23 is large, and when the amount of electricity to the heater 22 is small and the radiation amount is small, the amount of radiation is small. Since a certain amount can be expressed by the brightness of the radiator 21 and can be visually judged at a glance, the operation can be facilitated.

Next, by disposing the light source 23 on the side surface of the radiator 21, the generated radiant energy can be effectively used as heating without interrupting the radiant energy generated from the radiator 21 by the light source 23. Further, by disposing the light source 23 on the side surface of the radiator 21, since the area of the radiation surface facing the light source 23 is small, heating by the radiation energy of the light source 23 can be suppressed, and the light source 23 due to overheating can be suppressed. Failure can be prevented.

Next, a coating containing a photocatalyst activated by irradiating the radiation surface of the radiator 21 with light such as titanium oxide was applied to form a film. Then, the light emitted by the light source 23 activates the photocatalyst, so that air contaminants such as aldehyde contained in room air convection near the radiation surface can be removed by the catalytic action.

Next, by making the superheat source of the radiator 21 a combustion unit that burns a combustion heat source using gas or oil as a fuel, it is possible to provide a device that can provide a large-capacity heating capacity economically and inexpensively. At the same time, in order to provide a large capacity, a radiation area is increased, and a danger due to a tentacle or the like is increased in order to increase a radiation surface temperature to increase a radiation ability. Irradiating the radiator 21 indicates that the radiator 21 is in a heated state, thereby preventing an unsafe act by a tentacle or the like.
