Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a sauna equipped with a display device that provides an indication of the amount of perspiration.

Structure of conventional sauna and its problems A conventional sauna has a structure as shown in FIG. Reference numeral 1 denotes a housing into which a bather enters, and a heater 2 for heating is installed inside the housing 1, and a variable thermostart 3 controls the internal temperature. However, when taking a bath for the purpose of sweating, there was the disadvantage that the amount of sweat produced could only be determined based on the individual's own sense of how the sweat was produced. Furthermore, when I think about changing the temperature in the sauna, I find that the only way to judge is by personal feeling.

OBJECTS OF THE INVENTION The present invention provides a sauna with a display device that serves as a guide for the amount of perspiration in order to solve the above-mentioned problems.

Structure of the Invention In order to achieve the above object, the sauna of the present invention has the following features:
A housing into which a user enters and takes a bath, a heater installed inside the housing, a temperature setting means for the user to arbitrarily set the temperature inside the housing, and the housing. a temperature detection element for detecting internal temperature; a comparator for comparing the output of the temperature detection element with the output of the temperature setting means; and an energization control means for controlling energization to the heater based on the output of the comparator. , a bathing start switch operated by the user at the start of bathing, an oscillator that starts oscillating by the bathing start switch and whose oscillation period is set by the output of the temperature detection element, and a counter that counts the number of output pulses of the oscillator. , a display that displays the count value of this counter, and with this configuration, the amount of perspiration can be displayed reliably.

DESCRIPTION OF THE EMBODIMENTS The structure of the present invention is as shown in the block diagram of FIG.

A heater 2 is installed inside a housing 1 into which a user enters to take a bath.

A comparator 6 that compares the temperature setting means 4 that allows the user to arbitrarily set the temperature inside the casing 1 with a temperature detection element 5 that detects the temperature inside the casing 1, and the output of the comparator 6. The temperature inside the sauna is adjusted to an arbitrary temperature by the energization control means 7 which controls the energization of the heater 2.

When the user enters the housing 1 and operates the bathing start switch 8, the oscillator 9 starts oscillating at an oscillation period corresponding to the temperature of the temperature detection element 5. At this time, the temperature detection element 5 shortens the oscillation cycle as the temperature increases.

Next, by sequentially lighting up the display 11 for each predetermined value of the counter 10 that counts the number of output pulses of the oscillator 9, an indication of the amount of perspiration is displayed.
The higher the temperature, the more the human body sweats.
The longer the bathing time, the more the amount of sweat, so the configuration of the present invention makes it possible to realize a sauna with a display device that can be used as a guide for the amount of perspiration.

Next, a detailed explanation will be given using FIG. 3.

A variable resistor 4 which is a temperature setting means and a thermistor 5 which is a temperature detection element.
is connected to an 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.

That is, information on the temperature inside the housing 1, information on the set temperature, and information on whether or not bathing has started are input to the microcomputer 21.

If the temperature inside the housing is lower than the set temperature,
By driving the transistor 24, the microcomputer 21 closes the contacts of the relay 7, which is the energization control means, and energizes the heater 2.
Conversely, when the temperature inside the housing is high, the temperature is controlled to a desired temperature by stopping the power supply.

Further, when the bathing start switch 8 is closed, the microcomputer 21 determines that bathing has started, and sequentially turns on the plurality of light emitting diodes 11, which are indicators, at a time corresponding to the temperature of the thermistor 5. In Fig. 3, light emitting diode 1
The number of 1's is 3, but there is no problem in increasing the number.

That is, the comparator 6 shown in the block diagram of FIG.
Oscillator 9, counter 10, microcomputer 2
1 is being substituted.

Next, explanation will be given using the flowchart shown in FIG.

After adjusting the variable resistor 4 to the position corresponding to the desired temperature, the microcomputer 2
For 1, enter the set temperature and set it as T ₀
[°C]. Next, in step 2, thermistor 5
Enter the temperature in the same way, and let this be temporarily T ₁ [°C]. Next, in step 3, compare T ₀ and T ₁ ,
When T ₀ ≧ T ₁ , an energizing signal is output to the heater 2 in step 4, and when T ₀ < T ₁ , the energizing signal to the heater 2 is not output as in step 5, and T ₀
The temperature inside the housing 1 is controlled to [°C].

In step 6, it is determined whether or not bathing has started, and when bathing has started, in step 7, measurement of time _t0 is started. Next, in step 8, an oscillation period Tx corresponding to the temperature _T1 of the thermistor is determined. (i.e.
Tx = f(T ₁ )) Next, in step 9, it is determined whether the above Tx time has elapsed, and if it has not yet elapsed, the counted value of the number of pulses N (however, the initial value is N = Since the value of (referred to as φ) is zero, in step 10, N, ie, φ light-emitting diodes 11 are turned on.

That means it's not lit at all.

Next, when the time Tx or more has elapsed in step 9, the measurement time is set to zero in step 11, and the number of pulses is counted (added) in step 12, and N=1.
Then, in step 10, the light emitting diode 11 is set to 1.
Turn it on. Then again, after the Tx time has passed,
The number of light emitting diodes 11 is two, and the number of light emitting diodes 11 is increased sequentially. Here, Tx time is the temperature of thermistor 5 T ₁
The higher the temperature, the shorter the time, so if you set the temperature to a high temperature and take a bath, the time interval at which the light emitting diode 11 lights up will become shorter. In other words, when the temperature is high and the amount of sweat increases, the time interval between sequential lighting of the light emitting diodes will be automatically shortened.
Whether you take a bath at a low temperature or a high temperature, if you wait for the same number of light emitting diodes to light up before you finish your bath, you will end up sweating about the same amount. However, the higher the temperature, the shorter the bathing time.

In this embodiment, a microcomputer is used, but the oscillator is composed of a capacitor, a resistor, and a comparator, and the oscillation period is varied depending on the temperature by using the resistance change of the thermistor 5, and the counter is an IC. A similar effect can be obtained by using a counter.

Effects of the Invention As is clear from the description of the embodiments described above, according to the sauna of the present invention, even if the temperature is arbitrarily changed and the bath is finished, the number of indicators is used as a guideline to prevent a person from receiving an electric shock. You can always get about the same amount of sweat without relying on it.
