Conventional configuration and its problems A conventional sauna has a configuration as shown in FIG. Reference numeral 1 denotes a housing into which a bather enters, and a heater 2 for heating the person and air is installed inside the housing 1, and a variable thermostat 3 controls the internal temperature. However, when you take a bath for the purpose of sweating, the amount of sweat produced is
This method had the disadvantage that sweat production could only be judged based on individual sensations. Furthermore, if the temperature inside the sauna changes, the amount of sweating will naturally change, and the only way to judge this is by feeling it on your own.

OBJECTS OF THE INVENTION In order to solve the above problems, the present invention provides a sauna that can always display a stable amount of perspiration.

With this configuration, it is possible to make corrections for individual differences in the sweat amount display, so it is always A stable and accurate amount of perspiration can be displayed.0 Description of an Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In FIG. 2, a heater 2 is installed inside a housing 1 into which the user enters and takes a bath, and a temperature setting means 4 for the user to set the temperature inside the housing 1 is provided. body 1
The interior of the sauna is controlled by a first comparator 6 that compares the temperature inside the sauna with a temperature detection element 5, and an energization control means that controls energization of the heater 2 based on the output of the first comparator 8. Can be adjusted to any temperature.

Next, when the user operates the bathing start switch 8 when taking a bath, the timer 9 starts operating.

On the other hand, the humidity detection element 1o detects that the humidity inside the housing increases due to the person's sweating, and this output is compared with a predetermined value by the second comparator 11. When the humidity exceeds the predetermined value, The second comparator 11 outputs a signal. When this second comparator outputs, the value of the timer 9 is stored in the time storage means 12, and the oscillator 13 starts oscillating at an oscillation period set by the output of the temperature detection element 5 and the output of the time storage means 12. let

A counter 14 is provided to count the number of output pulses of the oscillator 13, and a plurality of indicators 16 are provided to display the count value of the counter 14 by emitting light every predetermined value, thereby displaying the amount of perspiration.

The oscillation period of the oscillator 13 at this time is made shorter as the temperature inside the housing 1 is higher and as the numerical value stored in the time storage means 12 is smaller. This is because the higher the temperature, the more the human body sweats, and the difference between individuals in the amount of sweat when taking a bath at the same temperature is that the shorter the time it takes for sweat to actually start, the easier it is to sweat. This is because the amount of sweat increases, and the longer the bath time, the more the amount of sweat.

An embodiment of the present invention will be explained in more detail using FIG. A variable resistor 4 which is a temperature setting means, a thermistor 6 which is a temperature detection element, and a humidity detection element 1
o is connected to the input port of the microcomputer 21 via an analog multiplexer 22 and an A/D converter 23, and a bath start switch 8 is also connected to the input port.

Temperature information, humidity information, set temperature information, and information as to whether bathing has started are input into the microcomputer 21.

Here, when the temperature inside the housing 1 is lower than the set temperature, the microcomputer 21 closes the contact of the relay 7, which is the energization control means, by driving the L transistor 24, and energizes the heater 2. Conversely, when the temperature inside the casing 1 is high, the temperature inside the casing 1 is controlled to an arbitrary temperature by stopping the power supply.

1. When the bathing start switch 8 is closed, the microcomputer 21 determines that bathing has started, and the thermistor 5 is activated.
The time interval for lighting up the light emitting diodes 15, which is a plurality of indicators, is determined based on the temperature and the time required for the output of the humidity detection element 10 to exceed a predetermined value. The operation of displaying the sweat amount is started when the sweat amount exceeds a predetermined value.

In this embodiment, the number of light emitting diodes is three, but there will be no problem even if the number is increased.

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

When the variable resistor 4 is adjusted to the position corresponding to the desired temperature, the microcomputer determines the set temperature in step 1.
Enter C and temporarily set it as To [°C]. Next, in step 2, the temperature of the thermistor 5 is input in the same way, and this is temporarily set as T1['cl. Next, in step 3, T
o and T1 are compared, and when T0≧T1, an energization signal is output to the heater 2 in step 4, and when To<T1, an energization signal is output to the heater 2.
Do not send the energization signal to heater 2 as shown in
The temperature inside the housing 1 is controlled to To [°C].

In step 6, it is determined whether bathing has started, and when bathing has started, step 7 determines time t.

It is determined whether the measurement of time t0 has already been completed, and if it has not been stored yet, the measurement of time t0 is started in step 8, and in step 9 it is determined whether the humidity has increased due to sweating and exceeded a predetermined value.

When the humidity reaches a predetermined value or higher, time measurement is ended in step 10, and this elapsed time t0 is stored. Next, in step 11, the oscillation period is adjusted to the temperature T1 of the thermistor 6 [℃
] and is determined at the stored time t0. That is, T
It is expressed as x−f(T1.to). In step 12, measurement of time t1 is started in order to generate a pulse from the oscillator.

Next, in step 13, it is determined whether the above-mentioned Tx time has elapsed, and in step 14, the light emitting diodes corresponding to the counted number of pulses N are turned on. If a certain amount of time has not elapsed, the value of the count value N is zero, which means that the light is not lit.

Next, when the time Tx or more has elapsed in step 13, the measurement time is set to zero in step 15, and in step 16,
Count (add) the number of pulses, set it to N-1, and proceed to step 1.
4, one light emitting diode 16 is turned on. Next, Tx
After a period of time has elapsed, two light emitting diodes 15 light up.
The number increases sequentially. Here, the Tx time is made shorter as the temperature T1 of the thermistor 5 is higher, so if the sauna is set to a high temperature and the user takes a bath, the time interval at which the light emitting diode 15 lights up becomes shorter. Also, the time t until you start sweating. Since the Tx oscillation cycle is set to be short even when the oscillation period is short, the time it takes for the light emitting diode 15 to turn on will be shorter for people who start sweating for a shorter time, that is, for people who sweat more. The interval becomes shorter.

Therefore, the effects of individual differences in temperature and perspiration are automatically corrected,
A sauna with a stable display device that is always proportional to the amount of sweat can be realized.

In addition, in this embodiment, the microcomputer 1
However, it is also possible to configure the oscillator 13 from a capacitor, a resistor, and a comparator, change the oscillation period depending on the temperature by using the resistance change of the thermistor 5, and use an IC counter or the like as the counter. A similar effect can be obtained.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention, the temperature of the sauna can be changed arbitrarily while taking a bath, and the number of indicators can be changed even if the user's sweating amount is different. As long as you finish your bathing as a guideline, you can always get about the same amount of sweat without relying on your senses, and the effect is tremendous.
