Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a sauna bath that provides a pleasant warm sensation during bathing.

BACKGROUND OF THE INVENTION Conventional electric sauna baths use so-called mechanical thermostats to control the temperature inside the room, and turn the heater on and off.
was repeated.

Problems to be Solved by the Invention According to this method, when a user takes a bath, the set temperature is reached and the heater is turned OFF.As time passes, the temperature begins to drop and the heater is turned OFF before being energized again. Since there is no radiant heat from the heater, the user may feel that the temperature is lower than the set temperature before the body warms up, which is extremely uncomfortable. Therefore, the thermostat was set low during preheating, the set temperature was raised when bathing, and the heater was turned on while bathing, but this was time consuming and inconvenient. The present invention eliminates such drawbacks,
The purpose is to provide a sauna bath that gives a pleasant feeling of warmth when taking a bath.

Means for Solving the Problems In order to solve the above problems, the present invention introduces a preheating switch and a bathing switch, so that the temperature during preheating is adjusted to a lower temperature than during bathing.

Effect: By using the above means, when the user presses the bathing switch during bathing, the heat source is always turned on, apart from the normal temperature setting means, and the user can get a pleasant feeling of warmth.

Embodiment FIG. 1 is a block diagram of an electric sauna bath according to an embodiment of the present invention. 1 is a preheating switch that starts preheating the sauna room; 2 is a bathing switch that the user presses before taking a bath; 3 is a heat-sensitive means that detects the temperature inside the sauna room; 4 is a temperature setting means that sets the temperature inside the sauna room; 6 numeral 6 is a temperature control means that inputs the outputs of these 1 to 4 and adjusts the temperature inside the sauna room; and 6 is a load control means that energizes the heater 7 that heats the sauna room using the output of the temperature control means 6. When the preheating switch 1 is pressed, the temperature adjusting means 5 adjusts the temperature in the sauna room to a temperature lower by a predetermined value than the temperature set by the temperature setting means 4.

FIG. 2 is a circuit diagram of one embodiment of the present invention.

Reference numeral 11 denotes an AC power source with contacts 12 and a heater 13 (corresponding to heater 7 in FIG. 1) connected in series at both ends. Contact 12
is opened and closed by the coil 14.

The coil 14 is connected in series with the transistor 15 and the DC power supply +1. On the other hand, the DC power supply +■2 has a resistor of 18,
A switch 19 (corresponding to the preheating switch 1 in FIG. 1), a resistor 20 and a resistor 21, a switch 22 (corresponding to the bath switch 2 in FIG. 1), and a resistor 23 are connected in series, and the switch 19, the resistor 2o, and the switch 22 are connected in series. The connection point between the resistor 23 and the resistor 23 is connected to the microcomputer 340 input.

Further, a thermistor 24 (corresponding to the heat sensitive means 3 in Fig. 1), a resistor 25, a variable resistor 26 (corresponding to the temperature setting means 4 in Fig. 1), and a resistor 27°28 are connected in series to the DC power supply +v2, respectively. ing. The thermistor output and the output of the variable resistor 26 are input to a comparator 29, and the output of the comparator 29 is input to a microcomputer 34 via a pull-up resistor 30. The collector of the transistor 31 is connected to the connection point between the resistors 27 and 28, and the base receives a direct current,
The connection point of resistors 32 and 33 connected in series between the power supply +72 and the output of the microcomputer 34 are connected. The resistors 16 and 17 are connected in series to the DC power supply +v2, and their common point is connected to the transistor 150 and the microcomputer 34.

In the above embodiment, when the switch 19 or 22 is turned on, the microcomputer 34 operates, the transistor 16 is turned on, current flows through the coil 14, the contact 12 closes, and the heater 13 starts to be energized. and variable resistor 26
The comparator 29 operates and outputs the output to the microcomputer 34 based on the set value of and the potential of the thermistor 24 and the resistor 25 relative to the reference potential of the resistor 27 (or resistors 27 and 28). And this microcomputer 34
The transistor 15 is turned on and off by the output, and the heater is turned on and off by the action of the coil 14 and the contact 12, thereby controlling the sauna room to the set temperature.

There are two types of temperature control, preheating switch 1 in Figure 1.
When the switch 19 corresponding to
The temperature is regulated at a low temperature. Subsequently, when the switch 22 corresponding to the bathing switch 2 in FIG. 1 is pressed, the transistor 31 is turned off, and the temperature is adjusted to the set temperature of the variable resistor 26.

FIG. 3 is a flowchart showing the operation of one embodiment of the present invention.

Turn on the power f) and wait until preheating or bathing switch 1 or 2 is pressed at 1o1. When either switch is pressed, the heater 7 is turned on at 102, and it is determined at 103 whether the pressed switch is preheating or bathing. Preheating switch at 10 o'clock is 104
The set value of the indoor temperature is set lower by a predetermined value. When the bathing switch 2 is set, the setting remains unchanged at 105. When the indoor temperature rises due to the energization of the heater 7 and exceeds the set value at 106, the heater 7 is turned off at 107, and when the indoor temperature falls, the heater 7 is turned on at 108. The temperature is adjusted in this way, but when another switch is pressed next at 108, the process returns to 103 and the set value is reviewed and the temperature is adjusted using the new set value. When the power is turned off at 108, the sequence ends.

In this embodiment, an electric type heater 13 is shown, but the effects of the present invention will not change in any way even if gas, oil, etc. are used as the heat source.

Effects of the Invention As described above, according to the present invention, with the simple operation of pressing the bath switch before bathing, the setting is increased from that during preheating, and the heater is always turned on immediately after bathing to provide ONL users with a pleasant warm sensation. You can get it.
