Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a temperature control device for a sauna bath that uses a heater such as a far-infrared heater as a main heat source.

(Prior Art) Sauna baths that use a heater such as a far-infrared heater as a heat source are already well known. Conventionally, the third
If the bathroom 1 is box-shaped as shown in the figure, 450W heaters A and B are installed at the front left and right inside the bathroom 1, and a 230W heater C is installed at the bottom of the bathroom 1. ing.

Heater C is constantly operated. Both heaters A,
At the beginning of startup, B is connected in parallel to the power supply and operated at full output. When a certain temperature, say 60°C, is reached, they are switched in series and operated at half output. Thereafter, the predetermined temperature is maintained by turning heaters A and B on and off with respect to the power supply.

However, if heaters A and B are turned off after reaching the predetermined temperature, the internal temperature will drop rapidly and overrun, so even if they are turned on next time, they will not reach the predetermined temperature. It will take a long time to do this. During this time, the bather feels cool, and the sweating effect decreases during this time.

(Problem that the invention aims to solve) The purpose of this invention is to control the temperature after it has risen to a predetermined temperature so that the low temperature does not continue, so that the bather does not feel cool. shall be.

(Means for solving the problem) This idea has two heaters installed on each side of the front left and right sides of the bath room, one of which is operated at all times, and the other one is set to a specified temperature. It is characterized in that it maintains a predetermined temperature by turning on and off after reaching the temperature.

One of the heaters installed at the front left and right of the bath room is always in operation, so even if the other one is turned on and off to maintain the specified temperature, the temperature inside the room will drop rapidly. There isn't. Therefore, there is no possibility that the temperature decrease will overrun, and therefore, the next time all the heaters are put into operation, the temperature will immediately rise.

(Example) An example of this invention will be described with reference to the drawings. Reference numeral 1 denotes the above-mentioned bath room, in which heaters 2 to 6 such as far-infrared heaters are installed. To explain this specifically, the heaters 2 and 3 (output 280W) are installed on the front left and right sides of the bath room 1. Heater 4, 5
(output 185W) is installed below heaters 2 and 3. A heater 6 (output 200W) is installed at the bottom of the bath room 1. In addition, 7 is a hot air heater with an output of 570W.
This is used at startup. 8 in Figure 2
9 is a temperature regulator, 9 is a power regulator, and 10 is a power supply terminal.

The heaters 2 and 3 are connected in parallel to the power supply terminal 10. Further, the heaters 4 to 6 are connected in parallel to each other, and the parallel circuit is connected in series to the power supply terminal 10 via the contact b of the temperature regulator 8.

The contact a of the temperature regulator 8 is kept on after the power is turned on to the power supply terminal 10 until the temperature in the bath room 1 reaches a predetermined temperature, and is then turned off.

Contact b is normally turned off, and after the temperature in the bath room 1 reaches the predetermined temperature mentioned above and contact a is turned off, when the temperature drops by a certain range from the predetermined temperature. It's becoming more and more turned on.

In the above configuration, when the power is turned on, the heaters 2 and 3 start operating. Further, since the contact a of the temperature regulator 8 is turned on at the beginning of startup, the hot air heater 7 is operated thereby. As a result, the temperature inside the bath room 1 increases.

When this reaches a predetermined temperature (for example, 60° C.), contact a is turned off. By turning off the hot air heater 7, the hot air heater 7 is stopped. When the temperature decreases by a certain range after the predetermined temperature, contact b is turned on. As a result, the heaters 4 to 6 start operating.

Then, when the temperature rises and reaches the predetermined temperature again, contact b is turned off and the operation of heaters 4 to 6 is stopped. By repeating this process, a predetermined temperature is maintained. Note that once contact a is turned off, it remains off until it is activated next time.

Even when the contact point b is turned off, the heaters 2 and 3 on the left and right sides of the front still continue to operate. Therefore, for bathers, heaters 4~
Even if the operation of 6 is stopped, the user does not feel much cooler, and the sweating effect continues as before.

Since no overrun occurs due to the temperature drop at this time, the next time contact b is turned on, the temperature will rise rapidly.

In addition, after the temperature in the room reaches a certain temperature, temperature adjustment is now performed by some heaters on the left and right front and a heater at the bottom.In other words, the heat applied from the front and bottom of the bather Since the temperature is adjusted accordingly, the temperature can be adjusted while giving heat almost evenly to the bather.

(Effects of the invention) As detailed above, according to this invention, the temperature can be controlled without making the bather feel cool, and the control does not overrun, so the predetermined temperature can be maintained. The temperature can be maintained reliably, and the predetermined temperature can be maintained while applying heat almost uniformly to the bather.
