For example, a CdS (photoconductive cell) is used. Used.

The save controller 41 inputs the brightness signal from the brightness detector 40 according to the operation flow chart shown in FIG. 9, and judges whether the brightness around the floor 24 is lower than a predetermined brightness. However, if it is bright, the set temperature of the temperature controller 42 is not changed as it is, and if it is darker than a predetermined brightness, the set temperature of the temperature controller 42 is lowered or the save control signal for changing the setting to the minimum temperature is used.

When w is turned on, the frequency converter 21 converts the frequency of the commercial power source of 50 Hz / 60 Hz into AC power of low frequency of 14 Hz, for example, and outputs the AC power.

The temperature controller 42 supplies the planar heater 23 with the low-frequency AC power of 14 Hz converted by the frequency converter 21, the voltage value of which is controlled by, for example, a variable resistor.

Therefore, the sheet heater 23 receives the supply of the AC power having a low frequency of 14 Hz to generate heat and raise the temperature of the floor 24. Thus, during floor heating, the brightness detector 40
Outputs a brightness signal according to the brightness of the surroundings where the floor 24 is installed.

In step # 1, the save controller 41 inputs the brightness signal output from the brightness detector 40 and determines whether the brightness around the floor 24 is lower than a predetermined brightness. .

As a result of this judgment, if the brightness around the floor 24 is brighter than the predetermined brightness, the save controller 41
In step # 2, it is determined that the set temperature of the temperature controller 42 should not be changed.

However, when it is determined that the brightness around the floor 24 is lower than the predetermined brightness, the save controller 41
In step # 3, it is determined whether or not the set temperature in the temperature controller 42 has dropped, for example, every predetermined period.

As a result of this judgment, if the set temperature of the temperature controller 42 is lowered, the save controller 41 again executes the step #
Returning to step 1, the brightness signal output from the brightness detector 40 is input to determine whether the surrounding brightness of the floor 24 is darker than a predetermined brightness.

However, if the set temperature has not dropped in the temperature controller 42, the save controller 41 proceeds to step #
4, the save control signal for lowering the set temperature of the temperature controller 42 or changing the setting to the minimum temperature is sent to the temperature controller 42.

When the temperature controller 42 receives the save control signal from the save controller 41, the temperature controller 42 lowers the set temperature from the present temperature or changes and sets it to the minimum temperature. On the other hand, when the two changeover switches k ₁ and k ₂ are switched and connected to the ion side i, respectively, negative ions (-) are supplied to the planar heater 24, thus acting as an ion therapy function. In the third embodiment, the brightness detector 40 detects the brightness around the floor 24, and when the brightness around the floor 24 becomes darker than a predetermined brightness, the set temperature of the temperature controller 42 is set. Since the temperature is lowered or the setting is changed to the minimum temperature, it is possible to save the power in a situation where there is no human, for example, at night when the sheet heater 23 is energized, or when the light is turned off from the room.

Further, if the heating device is switched off in consideration of the waste of power consumption when leaving the heating device for a short time, the temperature of the heating device will drop when returning, but this embodiment Then, only by turning off the lighting, it is possible to maintain the heat retention effect, that is, only the minimum temperature, and immediately return the temperature of the heating device to the target temperature.

When the ambient brightness becomes darker than the predetermined brightness in this way, the operating method of lowering the set temperature of the temperature controller or changing the setting to the minimum temperature is not limited to the floor heating device, but an electric futon It can be applied to electric carpets, electric blankets, folding heating devices, and even hot air blowers.
