Description

[Detailed description of the invention] Industrial applications The present invention relates to an electric sauna bath.

Conventional example (11 configuration and its problems) A conventional electric sauna bath has a configuration as shown in Fig. 4. In the figure, 1 is a housing into which the user enters and takes a bath. A heater 2 was installed inside to heat people and the air, and a variable thermostat 3 controlled the internal temperature.

Moreover, there was also a device with a wind-up timer that would dynamically turn off the heater 2 after a certain amount of time had elapsed. However, if you want to change the temperature inside the electric sauna bath while taking a bath, or if the mainspring timer turns off while taking a bath, you will have to go outside because the control knob is located outside the electric sauna bath. As a result, the temperature of the i+ inside the sauna bath dropped, causing the heated body to become cold. Also, when you take a bath to sweat, you use an hourglass to find out how long you have been in the bath, but you have to turn the entire hourglass over and over again, and how many times does it take?
This was a nuisance for the bather, as the bather had to remember whether or not the item had been returned.

Further, reference numeral 11 denotes a temperature detection element, which is attached to detect the temperature inside the housing 1. A comparator 12 compares the output of the temperature detecting element 11 with the output of the resistor group 1o. Based on the output of the comparator 12, an energization control means 13 controls energization to the heater 2. And 1
4 is a temperature detection circuit having an output that changes according to the output of the temperature detection element 11; 15 is a plurality of light emitting indicators provided outside and inside the housing 1; The temperature inside the housing 1 is displayed, and 16 is a set temperature display means, which causes the light emitting display 15 to sequentially flash and emit light in accordance with the output of the output switching means 9.

Further, the specific circuit and operation will be explained based on FIGS. 2 and 3. Components that are the same as those shown in FIG. 1 are designated by the same numbers, and the description thereof will be omitted.

As shown in FIG. 2, this actual example consists of a microcomputer 17 and its peripheral circuits. The microcomputer shown here is a so-called one-chip microcomputer consisting of a CPU, ROM, RAM, and input/output board.

Preheating start switch 4. Bathing start switch5. External and internal temperature setting switch 8a. 8b is connected to the input port of the microcomputer 17, and the thermistor 11, which is a temperature detection element, is also connected to the input port via the A/D converter 18. In other words, information on whether preheating has been fully started, information on whether bathing has started, information on whether to change the temperature setting, and information on the temperature inside the housing 1 are input to the microcomputer 17.

The resistors of the resistor group 10 are sequentially turned on in accordance with the set temperature, and the comparator 12 compares the output of the thermistor 11 to drive the transistor 19, thereby opening and closing the contacts of the relay 13, which is the energization control means. , the temperature inside the housing 1 is controlled by controlling the entire flow to the heater 2 . In addition, external and internal time display means 7a, 7b and external and internal light emitting indicators 14a, 14b, each comprised of a number of light emitting diodes, are connected to the output port of the microcomputer 17 through resistors, respectively. . Here, in FIG. 2, the number of light emitting diodes is four each, but there is no problem even if there are more.

Furthermore, the output port of the microcomputer 17 is directly connected to the base of the transistor 19, so that the power supply to the heater 2 can be stopped.

That is, the timer 6° output switching means 9 shown in the block diagram of FIG. Temperature detection circuit 14. This means that the microcomputer 17 is substituted for the set temperature display means 16.

Next, the entire operation will be explained using the flowchart shown in FIG.

Set preheating start switch 4 or bathing start switch 5 to 1ψ
Then, it is determined that preheating or bathing has started in step 1 or step 2, and the process goes to step 3, at time t. Start measuring. Next, in step 4, if the temperature setting switch 8 is pressed, the process advances to step 5, and N, whose initial value is 4 (in this embodiment 1, C; L temperature is set to 4 levels) is subtracted by 1. Then, in step 6, N
If is not zero, proceed to step 7. Further, if the temperature setting switch 8 is not pressed in step 4, the process proceeds to step 7.

Furthermore, if N is zero in step 6, N is set to the initial value of 4 (step 8) and the process proceeds to step 7.

Next, in step 7, the resistor of the resistor group 10 corresponding to the value of N is turned on, and the light emitting diode of the light emitting display 15 corresponding to the value of N is blinked. Next, in step 9, the temperature of the thermistor 11 is input, and this is temporarily set as T1(C).

Next, in step 1o, the light emitting display 15 corresponding to T1
The light emitting diode of t is turned on, and a further time t is elapsed. Time table corresponding to /J: The light emitting diodes of means 7 are sequentially turned on. Next, in step 11, if the bathing start switch 5 is pressed, time t is reached in step 12. Set it to zero and proceed to step 13. Further, if the bathing start switch 5 is not pressed in step 11, the process proceeds to step 13. Next, in step 13, time t. and constant 119 interval T. (40 minutes in this persimmon example), and when to<To, the process returns to step 4, and when t0≧To, the energization to the heater 2 is completely stopped in step 14, and the process returns to step 1.

In this way, when the preheating start switch 4 presses the bathing start switch 5, energization to the heater 2 is started, and when the temperature reaches the temperature set by the temperature setting switch 8, the energization to the heater 2 is started to maintain that temperature. Full control.

Then, when taking a bath, when the bathing start switch 5 is pressed, the timer 6 is reset and measurement starts again from zero. The time measured by the timer 6 is also displayed inside the sauna bath by the time display means 7, so that the bathers can always know the time they are taking a bath. Furthermore, since a temperature setting switch 8 is provided inside the sauna bath, the bather can change the temperature from inside the sauna bath. If the bather wants to extend the bathing time, the timer 6 can be reset by pressing the bathing start switch 5 until the end of the bath. In addition, since the bather does not have to go out during the bath, the temperature of γτ11 inside the sauna bath does not drop, and the body that has been warmed up does not get cold, making it easier to use. The effects on energy efficiency and energy conservation are significant.

Furthermore, when a second person takes a bath, if the bathing start switch 6 is pressed again, the timer 6 is reset and the time is displayed, making it convenient for the second person to easily understand the time.

As is clear from the description of actual examples that exceed the effects of the invention, the present invention has r
, fL, while taking a sauna bath, the bather can change the temperature or add time to the bath by changing the bathtub inside the sauna bath.

Furthermore, since the time you are bathing is displayed inside,
You will always know when you took a bath. Providing displays and operation switches inside the sauna bath in this way has tremendous benefits for bathers.
