Description

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

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. Inside this housing 1, a heater 2 for heating the person and the air is installed, and a variable thermostat 3 controls the internal temperature. However, when taking a bath for the purpose of sweating, there is a disadvantage in that the amount of sweat produced can only be judged by the individual's sense. Furthermore, when considering the situation where the temperature inside the sauna was different, the only way to judge was by personal feeling.

OBJECTS 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 even when the temperature inside the sauna and the perspiration of individuals vary.

Structure of the Invention In order to achieve the above object, the sauna of the present invention uses a housing in which a user enters and takes a bath, a heating element heater installed inside the housing, and a temperature inside the housing. a temperature setting means that can be arbitrarily set by a person; a temperature detection element that detects the temperature inside the casing; and a first comparator that compares the output of the temperature detection element with the output of the temperature setting means. , an 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, and a humidity detection element for detecting the humidity inside the casing. , a second comparator that compares the output of the humidity detection element with a predetermined value, and when the bathing start switch is operated and the second comparator reaches a predetermined value or more, the second comparator starts oscillating and detects the temperature. This configuration consists of an oscillator whose oscillation period is set by the output of the detection element, a counter that measures the number of output pulses from this oscillator, and a display that displays each time the counter reaches a predetermined value. By doing so, it is possible to always have a stable and accurate sweat amount display function.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below using the second part.

A heater 2 is installed inside the housing 1 into which the user enters and takes a bath. 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 6. Adjust to desired temperature.

Next, when the user operates the bathing start switch 8 after starting a bath, the humidity inside the housing 1 rapidly increases due to the sweating effect of the user. Therefore, this humidity is detected by the humidity detection element f9, and when the humidity becomes higher than a predetermined value by the second comparator 10, the oscillator 11 starts oscillating at an oscillation cycle according to the temperature of the temperature detection element f-5. .

Here, "according to the temperature of the temperature detection element 5" means that the higher the temperature, the shorter the oscillation period.

Next, count the number of output pulses of this oscillator 11.
The amount of perspiration is displayed by sequentially turning on the display 13 every predetermined value of the fi12 count.

The amount of sweat from the human body increases the higher the temperature and the longer the time spent in the bath, and the major factor behind individual differences in the amount of sweat is when sweating begins, so this can be detected by humidity detection elements. By detecting this, it is possible to correct variations due to individual differences and always display a stable amount of sweat.

Next, a detailed explanation will be given using the third example. A variable resistor 4, which is one stage of temperature setting, a thermistor 5, which is a temperature detection element, and a humidity detection element 9 are connected to the input port of the microcomputer 21 via an analog/romanometer 22 and an A/D converter 23. The bathing start switch 8 is also connected to the input port.

That is, temperature information inside the housing 1, humidity information, information on the set temperature, and information on whether or not the user has taken a bath are input to the microcomputer 21.

When the temperature inside the housing is lower than the set temperature, the microcomputer 21 drives the transistor 24 to
Close the contacts of relay 7, which is the energization control means,
The temperature is controlled to a desired temperature by supplying electricity to the heater 2 and, conversely, stopping the supply of electricity when the temperature inside the housing is high.

Here, when the bathing start switch 8 is closed, the microcomputer 21 determines that bathing has started, and when the output of the humidity detection element 9 exceeds a predetermined value, an indicator will appear for a time corresponding to the temperature of the thermistor 5. The plurality of light emitting diodes 13 are sequentially turned on. Although the number of light emitting diodes 13 in FIG. 3 is three, there is no problem in increasing the number of the light emitting diodes 13.

That is, the first comparator 6 and the second comparator shown in the block diagram of FIG.
Comparator 10. Oscillator 11. This means that the microcomputer 21 is substituted for the counter 12.

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

When the +4 variable resistor 4 is adjusted to a position corresponding to the desired temperature, the microcomputer inputs the set temperature in step 1 and temporarily sets it as 'rpc'c].

Next, in step 2, the temperature of the thermistor 5 is input in the same way, and this is temporarily set as T1. Next, in step 3, TO and T1 are compared, and when TO≧T1, an energization signal is output to the heater 2 in step 4, and when T, < TI, 1
In step 1, like a professional, the temperature inside the casing 1 is controlled at TD[''C] without issuing an energization signal to the heater 2.

Then, in step 6, it is determined whether bathing has started. When bathing has started, it is determined in step 7 whether the humidity has exceeded a predetermined value. If the humidity increases, proceed to step 8.
Start measuring time to.

Next, in step 9, an oscillation period 'rx corresponding to the temperature of the thermistor 5 is determined. (i.e., Tx=,/'(Tl
). ) Next, in step 1o, it is determined whether the above TX time has elapsed, and if the time has not elapsed, the count value of the number of pulses N
Since the value of is zero, it means that in step 11, the lamp is not fully lit.

On the other hand, if more than the TX time has elapsed in step 1o,
In step 12, the measurement time is set to zero, in step 13, the number of pulses is counted (added) and set to N-1, and in step 11, one light emitting diode 13 is turned on. moreover,
When the time Tx elapses, two light emitting diodes 13 are turned on, and the number of light emitting diodes 13 is increased sequentially thereafter. Here, the Tx time is made shorter as the temperature T1 of the thermistor 6 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 13 lights up becomes shorter. In other words, when the temperature is high and the amount of sweat increases, the time interval at which the light-emitting diodes light up in sequence is automatically shortened, so whether you take a bath at a low temperature or a high temperature, the same number of light-emitting diodes will emit light. If you wait for the diode to turn on and finish your bath, you will have sweated about the same amount.

Furthermore, when entering a sauna under the same conditions, individual differences in the amount of sweating are corrected by checking for sweating in step 7, since the time spent in the trench where sweating begins is a significant amount of time. It is possible to realize a sweat display device that is less affected by sweating.

Although a microcomputer was used in this embodiment, the oscillator was constructed from a capacitor, a resistor, and a comparator, and the oscillation period was varied depending on the temperature using the resistance change of the thermistor 5. I
A similar effect can be obtained by using a C counter.

Effects of the Invention As is clear from the description of the above embodiments, the present invention has the following advantages:
Even if you take a bath with the temperature of the sauna arbitrarily changed, and even if the amount of sweat between the users differs, if you use the table 7 Jk device as a guideline, you will be able to maintain the same amount of speech without relying on your senses. You can always get it, and its effects are tremendous.
