DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating device for a sauna bath capable of generating warm air and steam.

[0002]

2. Description of the Related Art In recent years, simple foldable sauna baths have been widely used in ordinary households. Conventionally, as a heating device used in a simple sauna bath, air is heated by a heater, and the heated air is blown out from a blowing pipe connecting the heating device and the bathroom to raise the temperature in the bathroom. I was The temperature in the bathroom can be set arbitrarily. That is,
By setting a temperature setting switch provided in the heating device to a desired temperature, the temperature in the bathroom can be set to that temperature.

[0003]

The hot air blown into the bathroom is blown in the same direction as the opening direction of the blow-out pipe. Therefore, for example, when the blowing pipe is directed to the vicinity of the feet, the warm air blown out from the blowing pipe is blown only toward the feet. After the warm air is blown out toward the feet, the warm air is circulated in the bathroom and is again sucked into the heating device from a suction pipe that sucks air in the bathroom.

[0004] The temperature of the hot air has been significantly reduced until hot air is blown out of the blow-out pipe and the hot air is sucked in through the suction pipe. That is, the temperature of the hot air decreases during circulation in the bathroom. Therefore, the temperature difference between the upper side and the lower side in the bathroom becomes large, and comfortable bathing cannot be performed.

[0005] In addition, the temperature in the bathroom and the temperature set by the temperature setting switch sometimes greatly differ from each other. The temperature in the bathroom is controlled by a controller. The controller compares the temperature in the bathroom detected by the temperature sensor with the temperature set by the temperature setting switch, and drives the heater when the actual temperature in the bathroom becomes lower than the set temperature to drive the heater. Raise the temperature. Further, when the actual temperature in the bathroom becomes higher than the set temperature, the driving of the heater is stopped (or the heater temperature is lowered), and the temperature in the bathroom is lowered.

Since the temperature sensor cannot be directly installed in a bathroom due to wiring and the like, it is provided in a suction pipe of a heating device. However, since the temperature detected by the temperature sensor circulates in the bathroom and is air whose temperature has decreased, a large error occurs between the actual temperature in the bathroom and the temperature detected by the temperature sensor. Therefore, for example, when the set temperature is 40 ° C., the heater is driven until the temperature sensor detects 40 ° C. However, actually, the temperature in the bathroom exceeds 40 ° C., so that the bather cannot comfortably take a bath.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a heating device for a sauna bath capable of making the temperature in a bathroom uniform and enabling a comfortable bathing. is there.
