Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a sauna having a function of displaying the amount of perspiration.

Conventional configuration and its problems A conventional sauna has a configuration as shown in Figure 1. Reference numeral 1 denotes a housing into which a bather enters, and a heater 2 for heating people and air is installed inside the housing 1, and a variable thermostat 3 controls the internal temperature. However, when taking a bath for the purpose of sweating, there was a disadvantage that the amount of sweat produced could only be judged by the individual's own sense of how the sweat was produced. Furthermore, if the temperature inside the sauna differs, the amount of sweat will naturally change, and there is no way to make a judgment based on individual feeling.

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

Structure of the Invention In order to achieve the above object, the present invention includes a housing in which a user enters to take a bath, a heating heater installed inside the housing, and a temperature control device for controlling the temperature inside the housing. A temperature setting means for arbitrarily setting the temperature, a temperature detection element for detecting the temperature inside the housing, a first comparator for comparing the output of the temperature detection element with the output of the temperature setting means, and the temperature detection element for detecting the temperature inside the housing. energization control means for controlling energization to the heater based on the output of the first comparator; a bathing start switch operated by the user at the start of bathing; a timer that starts operating based on the output of the bathing start switch; and the housing. A humidity detection element that detects internal humidity, a second comparator that compares the output of this humidity detection element with a predetermined value and outputs an output when the output is equal to or greater than the predetermined value, and a time point at which the second comparator outputs an output. an oscillator whose oscillation period is set by the output of the time output means and the output of the temperature detection element and starts oscillation by the output of the second comparator; It consists of a counter that counts the number of output pulses from the oscillator and a display that displays the value of this counter. With this configuration, it is possible to make corrections for individual differences in the sweat amount display, so it is always stable. It is possible to accurately display the amount of perspiration.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 2, a heater 2 is installed inside a housing 1 into which a user enters and takes a bath, and a temperature setting means 4 for setting the temperature inside the housing 1 by the user, A first comparator 6 that compares the temperature inside the body 1 with the temperature detection element 5
The temperature inside the sauna can be adjusted to a desired temperature by the energization control means 7 which controls the energization of the heater 2 based on the output of the first comparator 6.

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 10 detects that the humidity inside the housing increases due to the person's sweating, and this output is sent to the second
The second comparator 11 compares the humidity with a predetermined value, and 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 15 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. The amount of sweat from the human body increases as the temperature rises, and when bathing at the same temperature, the amount of sweat perspires varies from person to person.
This is because the shorter the time it takes for sweating to actually start, the more prone it is to sweating, which means the amount of sweating increases.
This is because the longer you take a bath, the more you sweat.

An embodiment of the present invention will be explained in more detail using FIG. A variable resistor 4 serving as a temperature setting means, a thermistor 5 serving as a temperature detecting element, and a humidity detecting element 10 are connected to an input port of a microcomputer 21 via an analog multiplexer 22 and an A/D converter 23. A bathing start switch 8 is also connected to the input port.

That is, temperature information, humidity information, set temperature information inside the housing 1, and information as to whether bathing has started are input to the microcomputer 21.

Here, when the temperature inside the housing 1 is lower than the set temperature, the microcomputer 21
4 closes the contacts of the relay 7, which is the energization control means, and energizes the heater 2. Conversely, when the temperature inside the casing 1 is high, the energization is stopped, so that the desired temperature can be reached. The temperature inside the housing 1 is controlled.

When the bathing start switch 8 is closed, the microcomputer 21 determines that bathing has started, and displays multiple indicators depending on the temperature of the thermistor 5 and the time until the output of the humidity detection element 10 reaches a predetermined value or higher. However, the time interval at which the light emitting diode 15 is turned on is determined, and the sweat amount display operation is started when the output of the humidity detection element 10 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, in step 1 the microcomputer inputs the set temperature and temporarily sets it as T ₀ [°C].
shall be. Next, in step 2, the temperature of the thermistor 5 is input in the same way, and this is temporarily set as T ₁ [°C]. Next, in step 3, T ₀ and T ₁ are compared, and T ₀ ≧T ₁
When T 0 < T 1, an energization signal is output to heater 2 in step 4, and when T ₀ < T ₁ , an energization signal is output to heater 2 in step 5.
The temperature inside the casing 1 is controlled to T ₀ [° C.] without issuing an energization signal to the casing 1 .

In step 6, it is determined whether bathing has started, and when bathing has started, time t ₀ is determined in step 7.
It is determined whether the measurement of time t0 has already been completed, and if it has not been memorized yet, the measurement of time _t0 is started in step 8, and it is determined in step 9 whether the humidity has increased due to perspiration 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 determined based on the temperature T ₁ [° C.] of the thermistor 5 and the stored time t ₀ . That is, it is expressed as Tx=(T ₁ , T ₀ ).
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 Tx time has elapsed, and in step 14, the count value N of the number of pulses is determined.
Light up the light emitting diode. If the elapsed time has not elapsed yet, the count value N is zero, which means that the light is not turned on.

Next, if the Tx time or more has elapsed in step 13, the measurement time is set to zero in step 15, the number of pulses is counted (added) in step 16, N is set to 1, and the light emitting diode is turned off in step 14. Light up one 15. Next, when the time Tx has elapsed, two light emitting diodes 15 are turned on, and the number of light emitting diodes 15 is increased sequentially thereafter.
Here, the Tx time is made shorter as the temperature _T1 of the thermistor 5 is higher, so if you set the sauna to a high temperature and take a bath, the time interval at which the light emitting diode 15 lights up becomes shorter. In addition, even when the time t ₀ until the start of sweating is short, the Tx oscillation cycle is set to be short, so the shorter the time it takes for the person to start sweating, that is, the person who sweats more, the more light is emitted. The time interval at which the diode 15 lights up becomes shorter.

Therefore, it is possible to realize a sauna with a stable display device that automatically corrects the influence of individual differences in temperature and sweating and is always proportional to the amount of sweating.

Although the microcomputer 21 is used in this embodiment, the oscillator 13 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 at this resistor. A similar effect can be obtained by using an IC counter or the like as a counter.

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 even if the user's sweating amount differs, the number of indicators can be adjusted. As a guideline, if you finish your bathing, you can always get about the same amount of sweat without relying on your senses.
The effect is tremendous.
