[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an infrared heating device that radiates infrared rays to warm a human body, and is, for example, to pursue comfort of heating in a house or office.

[0002]

2. Description of the Related Art Infrared rays are electromagnetic waves having a wavelength of 0.75 .mu.m to 100 .mu.m and have a property of heating an object. Therefore, devices and instruments utilizing this property are widely used. Particularly, as a device used in a residence or office, for example, as described in Japanese Patent Application No. 5-79389, a heating device utilizing direct heat transfer by infrared radiation, JP-A-63-11826. As described in Japanese Patent Laid-Open No. 62-253066, there is a sauna device that uses infrared rays as a heat source for a sauna. is there. By the way, these devices using infrared rays have a common point in that infrared rays are radiated and used at a constant density.

[0003]

However, especially in the case of a heating device, there is a drawback that a heating device that emits infrared rays at a constant density is not always comfortable for humans. In recent years, the performance of heating devices has improved, and it has become possible to keep the indoor temperature always constant in offices and the like. However, in this way, it is asked whether or not the space that is always kept at a constant temperature is a healthy and comfortable space for human beings, and researches on it have been started. According to the recent research results, it is rather uncomfortable for human beings to keep up with the constant change of the thermal environment like in a natural grove where the wind blows because the temperature is rather constant and the health is damaged. I also understand.

The present invention has been made in view of the above-mentioned circumstances, and by changing the radiation density of infrared rays, fluctuations of 1 / f can be given to the output of infrared heating, and infrared rays can be comfortably heated. The purpose is to provide a heating system.

[0005]

In order to solve the above-mentioned problems, an infrared warming device according to claim 1 has a heating element,
By controlling the infrared radiating means for radiating infrared rays by heating the heating element with electricity and the electric power supplied to the infrared radiating means, the amount of infrared radiation radiated from the infrared radiating means is changed, and the radiation is performed. And a power supply control means for giving 1 / f fluctuation to the quantity.

The infrared radiation device according to claim 2 is
It is characterized by being composed of an infrared radiator which shows a quick response to the control of electric power by the power supply control means.

Furthermore, in the infrared radiating device according to a third aspect of the present invention, a plurality of the infrared radiating means are provided, and the respective infrared radiating means are independently controlled by the power supply control means to radiate infrared rays. The feature is that the amount is changed to give 1 / f fluctuation to the radiation amount.

[0008]

According to the first aspect of the invention, the infrared radiation is emitted from the infrared radiation means by the electric power supplied from the power supply control means. Since the amount of infrared radiation emitted is accompanied by fluctuations of 1 / f, a person can feel a comfortable warmth close to nature.

According to the second aspect of the invention, the response of the infrared radiation means to the control of the electric power by the power supply control means is fast. Therefore, the 1 / f fluctuation is easily generated.

According to the third aspect of the present invention, the plurality of infrared radiation means are independently controlled in electric power by the power supply control means, whereby the radiation quantity of infrared rays is changed and the infrared radiation quantity is changed to the above radiation quantity. 1 / f fluctuation is given.
Therefore, since the infrared rays radiated from the respective infrared radiating means fluctuate in different cycles, a comfortable warmth can be felt in a state close to natural.

% To 90%. The heat-resistant glass 311 is formed in a semi-elliptical shape, and an aluminum reflecting surface (concave mirror) 312 is formed on the inner surface thereof. The aluminum reflecting surface 312 reflects the infrared rays emitted from the filament 313 and emits the rays as a parallel ray bundle or a divergent ray bundle. The filament 313 is made of tungsten or the like, and mainly emits near-infrared rays and visible rays by being energized and generating heat. The filament supporting portion 314 is for supporting the filament 313 in a high temperature state, and the base 315 electrically connects the infrared lamp 31 to a power supply circuit.

Each infrared lamp 31 is connected to a socket (not shown) in the housing 32 by screwing a base 314. At this time, each infrared lamp 31
Are connected in series in terms of a circuit, and are connected to output terminals O1 and O1 of the self-transmitting dimmer 2 via a cord 33. Also,
The resistance value of the filament 313 of the infrared lamp 31 changes as it is heated. Therefore, the effect of the firing angle (α angle) control by the triac of the self-transmitting dimmer 2 is added to the change in the resistance value, the infrared radiation density is changed, and the radiation with the fluctuation of 1 / f is realized. Yes, the warmth of the radiation is natural and comfortable for humans.

Next, the operation of the first embodiment will be described. The single-phase AC voltage is input to the rectifier circuit 21 via the input terminals I1 and I1, and the rectifier circuit 21 converts the AC voltage into a DC voltage. However, since this DC voltage is rectified by the diode, it contains a ripple component. The constant voltage smoothing circuit 22 removes a ripple component from the direct current component rectified by the rectifying circuit and outputs it to the stabilizing circuit 23. The stabilizing circuit 23 inputs the input DC voltage to the timer 24 as a more stable DC voltage. The resistance value of R1 is set so that the timer 24 has a predetermined cycle. Then, the timer 24 outputs a signal to the photocoupler fc to cause the photocoupler fc to emit light at a predetermined time, for example, 30 minutes. The photocoupler fc converts it again into an electric signal and sends it to the gate control circuit 27. The gate control circuit 27, which receives the signal from the timer 24 via the photocoupler fc, controls the transistor TR2 (FIG. 2) of the gate pulse generation circuit 26 so that the control angle becomes a predetermined control angle (α angle), and the triac. The TR is turned on and off to supply power to the infrared radiator 3. When the infrared radiator 3 receives power from the self-transmitting dimmer 2 via the noise prevention circuit 25 and the output terminals O1 and O1, the filament 313 in FIG. 3 is heated by the power and emits infrared rays and visible light. To do.
The emitted infrared rays and visible rays are reflected on the aluminum reflecting surface 31.
The light is refracted at 2, passes through the glass 312, and is output in one direction. The infrared rays output from the infrared radiator 3 are mainly near infrared rays, and do not always have a constant radiation density, but the radiation density fluctuates to 1 / f at intervals of a predetermined cycle. Therefore,
By bathing in the infrared rays, people can enjoy the natural and comfortable warmth of being in the sun.

Second Embodiment Next, a second embodiment of the present invention will be described.
