Description

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

Conventional configuration and its problems Figure 1 shows the configuration of a conventional sauna bath for general households. 1 is a wall material with internal insulation material such as rock wool or glass wool, and a plywood flush structure. The sauna box is surrounded by a sauna box, and a sauna room 2 is formed inside. 3 is a heat box in which a heating element 4 such as a sheathed heater is installed, and this heat box 3 is installed in the front part of the sauna room 2. 5 is a control unit equipped with a temperature controller such as a liquid expansion thermostat that adjusts the temperature of the sauna room 2, and a power switch that turns on and off the power to the sauna bath. It is provided on the outer top surface of the sauna box 1.

In the conventional example configured in this way, the temperature is set by operating the temperature controller, the power switch is turned on, and the air in the sauna room 2 is heated by the heating element 4 to reach a predetermined temperature. The temperature inside the sauna room 2 is regulated. in this case,
Users want to know how high the temperature inside the sauna room 2 is when they are in the middle of the day, but conventionally, there is no information that shows how the temperature inside the sauna room 2 is rising. Because of this, the user has to open the door several times to feel and check the temperature inside the sauna room with his or her skin, making it very inconvenient to use. Also, even while taking a bath, the bather may notice that the inside of sauna room 2 is
What temperature has it been? How long has it been since you started taking a bath? How much sweat have you been sweating? Is it different or the same as usual? In addition to being able to feel things through experience, we also want something visually appealing, such as indicators or current status.

Some conventional sauna baths come with accessories such as an hourglass that measures the approximate elapsed bathing time in the sauna room 2, and a bimetal temperature sensor that detects and displays the approximate temperature inside the sauna room 2. A meter was used. however,
In the case of an hourglass, it is usually a 6-minute timer, and bathing usually takes around 20 minutes, so every time 5 minutes pass, I am careful not to forget and flip the hourglass to check the time. If you don't keep measuring, you won't even know the approximate time. It is also possible to set the hourglass to 10 to 2 minutes, but in this case, even if you look at the hourglass and try to finish your bath in around 20 minutes, you won't be able to tell exactly how much time has passed. In addition, the hourglass has a certain amount of weight, such as fine iron powder, and the fluid PL changes without changing.The hourglass has a constriction in the center and contains sand at the top and bottom. The space to be stored was sealed in a container, and the ten floors of the container were supported by a frame made of resin or wood, and sand fell from the top to the bottom of the container. The hourglass is reversed to continue measuring time, but in this case,
In addition to the hassle of not being able to measure the time without inverting the hourglass each time, the container is made of glass, so if you touch the hourglass directly in sauna room 2, where the temperature is around 80"C, it will get hot and cause burns. It was highly dangerous, as it was made of thin glass and could break with the slightest impact, potentially causing injury.

In addition, a bimetal thermometer uses a bimetal with a thin band as a temperature detection part, converts changes in indoor temperature into the amount of warping of the bimetal, and transmits the movement to the display part that indicates the temperature. The display surface is made of glass or transparent resin, and the other parts are covered with light metal such as aluminum. This is sauna room 2
It is used by being attached to the inner wall surface of. However, in this case as well, since the outer frame is made of glass or metal, there is a risk of burns or injury for naked bathers in sauna room 2. This required caution.

The temperature change is converted into the amount of deformation of the metal, and the mechanical movement is transmitted to the temperature indicator and displayed.The structure is solid, and it is a large structure surrounded by metal, glass, etc. Because of this, it was difficult to display subtle temperature changes, and even if there was a large temperature change, the temperature of the bimetal itself did not change immediately, resulting in poor responsiveness. In most cases, this thermometer is installed in a place that is difficult to touch, for example, at the top of the inner wall of the sauna room 2, but the temperature distribution in the sauna room 2 is such that the temperature is high at the top of the room and decreases as you move from the center to the bottom. In a conventional sauna, the temperature difference between the top and bottom of the room is 40 to 5.
There is a temperature difference of about 20 to 30 degrees between where the bather is sitting and where the thermometer is installed, so the displayed temperature has only one meaning for the bather. It was something without.

OBJECTS OF THE INVENTION In view of these conventional problems, it is an object of the present invention to provide an electric sauna bath that is highly reliable, safe, and easy to use.

Structure of the Invention In order to achieve the above object, the electric sauna bath of the present invention has the following features:
A heating element for heating the inside of the sauna room is provided, and a temperature setting means and a timer means for setting the temperature inside the sauna room, or only a temperature setting means are provided, and the temperature and time inside the sauna room are electrically displayed, or either one of them. A display means for electrically displaying the information is provided inside or outside the sauna, or only inside the sauna. With this configuration, the temperature, time, etc. can be easily checked at any time, which eliminates the problems of the conventional sauna. As a result, it is possible to provide an electric bus that is highly reliable, safe, and easy to use.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

In the figure, 11 is a sauna box, and this sauna box 11 is equipped with a heat insulating material such as rock wool or glass wool, and has a front wall 12 of plywood flan structure, left and right walls 13, 14, and a rear wall 16. It is constructed by assembling a door 16 attached to the front wall 12 so as to be openable and closable, a top plate 17, and a floor plate 18 in a box shape. The inside of the sauna box 11 is divided into upper and lower parts by a tempura plate 19, and the upper part is a ceiling space (not shown), in which the sauna control circuit, control parts, etc. are housed. . The lower part of the deck is used as a sauna room 20. Reference numeral 21 denotes a front heat box containing a heating element 22, and one front heat box 21 is disposed at each of the left and right corners of the front of the sauna room 20.

23 is a rear heat box with a heating element 22 inside,
This rear heat box 23 is incorporated into the rear wall 16 of the sauna box 11. 24 is sauna room 2
This is a sensor cover that is attached to the inner wall surface of the sauna room 20 and houses a semiconductor temperature sensor such as a thermistor that detects the temperature inside the sauna room 20 and a humidity sensor that detects the humidity. Reference numeral 26 denotes an outer operating section provided above the outer front of the sauna box 11, and this outer operating section 25 includes an earth leakage breaker 26, a power switch 27, and a temperature setting button 28& for setting the temperature inside the sauna room 20. A temperature display section 29& that uses an electroluminescent element such as an LED to display the temperature setting value and the actual temperature of the sauna room 20 detected by the semiconductor temperature sensor inside the sensor cover 24;
A preheating button 30 that starts heating the sauna room 2o, and a time display section that measures the elapsed heating time of the sauna room 2o and the elapsed bathing time using an electroluminescent element such as an LED, which is measured by an electronic timer using an electrical oscillation circuit. It is equipped with 31 &. Reference numeral 32 denotes an inner operation section provided on the wall inside the sauna room 20, and this inner operation section 32 has a temperature setting button 282 of the outer operation section 25.
It is equipped with a temperature setting button 28b and a temperature display part 29b which are linked with the same function as L and temperature display FA 29 m, and these are operated at the start of bathing, and by this operation, the time display during preheating is erased, A bathing button 33 that counts the elapsed bath time and the amount of perspiration and continues heating the sauna room 20, a time display section 31b that displays the elapsed bath time, and The humidity sensor inside the sensor cover 24 detects the change in humidity during the period of queuing, and the humidity change is multiplied by the elapsed bathing time and a constant to approximate the amount of sweat of the bather, and the result is displayed as a guideline for the amount of sweat. Sweating display section 34
and an interior light switch 35.

The operation in the above configuration will be explained. 1. Before taking a sauna bath, operate the outer operation section 25. That is, set the earth leakage breaker 26 and the power switch 27 to [~], then press the temperature setting button 282L, and set the desired temperature while looking at the temperature display section 29&.

The lamp will blink at the set temperature.

After that, when the preheating button 30 is pressed, electricity starts to be applied to the heating element 22, and the sauna room 2o is heated.

In this case, since the elapsed preheating time is displayed on the time display section 312L, there is no need to leave the case preheated for longer than necessary. Furthermore, even if the heating element 22 is left energized for longer than necessary, the heating element 22 is configured to be de-energized after a certain period of time (approximately 90 minutes) to ensure safety.

As the temperature inside the sauna room 20 rises, the temperature display section 2
The lamps 9& will light up one by one starting from the low temperature side, so
You can see at a glance what the current temperature of the sauna room 20 is and whether it has reached the preset temperature. When the inside of the sauna room 20 reaches the set temperature and the lamp for the temperature display section 29 lights up from the low temperature side to the set temperature,
The light that was flashing at the set temperature changes to stay lit. It is also possible to notify you by sounding a buzzer when the set temperature is reached.

When the temperature inside the sauna room 2o reaches the set temperature, enter the sauna room 20 and press the bath button /33 to start sauna bathing. When the bathing button 33 is pressed, the lamps of the time display section 31b and the sweating display section 34 that were currently displayed on the inner operating section 32 go out and become O, and then the lamps of the inner operation section 32, which were currently displayed, go out and turn to "O", and from the time when the bathing button 33 is pressed 1, the lamps are turned off. It begins to be counted. The lamps on the time display section 31b are lit one by one according to the elapsed bathing time. Furthermore, when sweating begins, the lamp of the sweating display section 34 lights up depending on the degree of sweating. In addition, the temperature display section 29b indicates that the sauna room 20
Displays the current temperature. When the elapsed bathing time reaches 6 minutes, the power to the heating element 22 is automatically cut off.

Next, when taking a bath and wanting to change the temperature a little more, the bather presses the temperature setting button 28b on the inner operation section 32, looks at the temperature display section 29b, learns the current temperature, and adjusts the desired temperature. Since you can reset the temperature, you don't have to go out of the sauna room 2o to adjust it every time, and you can easily know the guideline for adjusting the temperature, so you can continue to enjoy a comfortable sauna experience. I can do it.

For the temperature detection part, we use an ultra-compact and highly sensitive semiconductor temperature sensor such as a thermistor to reduce the size.
Since it is separated from the display, it can be placed at any location suitable for temperature detection without taking up much space, and by correlating the temperature sensor output with the temperature in the center of the sauna room, you can easily determine the temperature in the center of the sauna room. can be displayed appropriately.

In this way, the sauna is equipped with a display that shows the temperature, time, sweating level, etc. inside and outside the sauna, so you can easily know the temperature, time, etc. at any time, and determine the economical timing that is suitable for bathing. It has great practical value, as it allows you to know when to finish a short bath, and also allows you to adjust the temperature and time appropriately.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, according to the present invention, display means for electrically displaying the temperature and time in the sauna room, or for electrically displaying either one of them, is provided in the indoor/outdoor sauna or in the sauna room. As a result, you can easily check the temperature, time, etc. at any time, and as a result, you can know when to start bathing and when to finish bathing, and you can also adjust the temperature and time appropriately, improving reliability. It is possible to provide an electric sauna bath which is high in quality, safe and easy to use.
