A water storage temperature sensor that detects the water storage temperature in the water storage tank, and
The heating heater compares the water storage temperature detected by the water storage temperature sensor with a predetermined switching temperature during normal operation in which the humidified air generated by the humidified air generating means is supplied to the sauna room by driving the blower fan. Equipped with a control unit that switches the ON / OFF state of
The normal operation can be set to a standard mode and a weak mode in which the rotation speed of the blower fan is set lower than that of the standard mode.
The control unit is characterized in that when the weak mode is set, the predetermined switching temperature is set higher than that of the standard mode.

Further, a room temperature setting means for setting a desired room temperature in the sauna room and a room temperature setting means.
A room temperature sensor that detects the room temperature of the sauna room is provided.
When the room temperature detected by the room temperature sensor during the normal operation becomes equal to or higher than the desired room temperature set by the room temperature setting means, the control unit switches the heater to the OFF state and detects it by the room temperature sensor. When the room temperature becomes lower than the desired room temperature set by the room temperature setting means, the ON / OFF state of the heater is compared with the water storage temperature detected by the water storage temperature sensor and the predetermined switching temperature.

According to the present invention, when a weak mode in which the rotation speed of the blower fan is lower than the standard mode is set during normal operation, the predetermined switching temperature is set higher than the standard mode, so that the temperature of the humidified air blown from the air outlet is the standard mode. Since the weak mode is higher than that in the weak mode, it is possible to prevent the room temperature from returning to a long time after the room temperature drops by opening and closing the door of the sauna room. It is possible to suppress the discomfort caused by the user taking a sauna bath when the room temperature is low.

When the room temperature detected by the room temperature sensor during normal operation exceeds the desired room temperature set by the room temperature setting means, the heater is switched to the OFF state, and the room temperature detected by the room temperature sensor is set by the room temperature setting means. When the temperature falls below a predetermined temperature lower than the desired room temperature, the ON / OFF state of the heater is switched by comparing the water storage temperature detected by the water storage temperature sensor with the predetermined switching temperature, so that the room temperature in the sauna room is desired. Since it is possible to prevent the room temperature from deviating from the room temperature and to prevent the room temperature from returning to the desired room temperature for a long time, it is possible to suppress the deterioration of the comfort of the sauna bath.

In addition, the predetermined switching temperature is a temperature obtained by adding a predetermined value to the desired room temperature set by the room temperature setting means, and the predetermined value is set to be larger in the weak mode than in the standard mode, so that the air is blown into the sauna room. The temperature of the humidified air is surely changed according to the desired room temperature, and the temperature of the humidified air blown in the weak mode is higher than that in the standard mode. Since it is possible to prevent the room temperature from returning for a long time after the temperature drops, it is possible to suppress the discomfort caused by the user taking a sauna bath while the room temperature is low for a long time. ..

By valve, water is supplied to the water storage tank 6, and dust, dust, bacteria and the like remaining on the bottom of the water storage tank 6 are washed and drained before the water is stored in the water storage tank 6.

(Explanation of cleaning mode)
Next, the operation of the cleaning mode will be described with reference to the flowchart of FIG.

The control unit 64 opens the drain valve 13 (step S101), determines whether the float switch 40 for low water level detection outputs an OFF signal (step S102), and the float switch 40 outputs an OFF signal. While it is determined that there is no such process, the process of step S102 is repeated, and when it is determined that the float switch 40 outputs an OFF signal, the water supply valve 8 is opened after a delay for a certain period of time (step S103).

When the water supply valve 8 is opened in step S103 and water supply to the water storage tank 6 is started, it is subsequently determined whether or not a predetermined time has elapsed (step S104), and when it is determined that the predetermined time has elapsed, drainage is performed. The valve 13 is closed (step S105), and the cleaning mode is terminated. If the predetermined time has not elapsed, the determination in step S104 is repeated.

When the cleaning mode of step S100 is completed, the process transitions to the sterilization mode A (step S200).
In this sterilization mode A, the energization of the heating heater 9 arranged near the inner bottom of the water storage tank 6 is turned on by the switching means 65 to heat the water in the water storage tank 6 to a temperature at which it can be sterilized, and the rotating body.

(Explanation of sterilization mode A)
Next, the operation of the above-mentioned sterilization mode A will be described with reference to the flowchart of FIG.

The control unit 64 determines whether the float switch 40 for detecting the low water level has output an ON signal (step S201), and when it is determined that the float switch 40 has output an ON signal, the control unit 64 heats the water in the water storage tank 6. The energization of the heating heater 9 is turned on by the switching means 65 , the drive of the mist motor 22 for rotating the rotating body 24 is started (step S202), and the hot water temperature in the water storage tank 6 detected by the water storage temperature sensor 44 is changed. It is determined whether or not it is at least a predetermined value (for example, 60 ° C.) that can be sterilized (step S203).

When it is determined in step S203 that the hot water temperature in the water storage tank 6 is 60 ° C. or higher, the control unit 64 turns off the energization of the heating heater 9 by the switching means 65 and at the same time heats the water in the water storage tank 6. Counting of the predetermined time for sterilization, that is, the sterilization time is started (step S204).

After step S204, the control unit 64 turns on the energization of the heating heater 9 when the hot water temperature in the water storage tank 6 detected by the water storage temperature sensor 44 becomes 58 ° C. or lower, and the water storage temperature sensor 44 detects the water storage. When the temperature of the hot water in the tank 6 reaches 60 ° C. or higher, the heating heater 9 is turned on by the switching means 65 so that the hot water temperature of the water storage tank 6 is kept at the sterilable temperature by turning off the energization to the heating heater 9. The / OFF state is switched (step S205), and the step S205 is repeated until the count for 1 minute, which is the sterilization time, is completed (step S206).

Then, if the control unit 64 determines that the counting of the sterilization time is completed (YES in step S206), the energization of the heater 9 is turned off (step S207), the sterilization mode A is terminated, and the sauna device is terminated. The preparatory operation is completed.

If it is determined in step S203 that the temperature of the hot water in the water storage tank 6 is lower than 60 ° C., the control unit 64 sends a signal to switch the energization of the heating heater 9 to the ON state by the switching means 65 , and then determines. It is determined whether 30 minutes have passed (step S208), and when it is determined that 30 minutes have passed since the signal was transmitted to switch the energization of the heater 9 to the ON state, the drain valve 13 is opened and the water storage tank. The water in 6 is drained, the switching means 65 is short-circuited, and the speaker 61 notifies by voice that it is impossible to switch the ON / OFF state of the energization to the heater 9 (step S209), and the sauna. Finish the preparatory operation of the device and do not proceed to the next step.

Further, if 30 minutes have not passed since the energization of the heater 9 was turned on in step S208 (No in step S208), it is determined in step S203 whether the hot water temperature in the water storage tank 6 is 60 ° C. or higher. repeat.

Further, when the float switch 40 outputs the ON signal in step S201 and then the water supply is continued and the float switch 41 for detecting the high water level outputs the ON signal, the control unit 64 closes the water supply valve 8 to supply water. The control unit 64 controls the water supply valve 8 to supply water based on the detection signal from the water level detecting means 39 (float switches 40, 41), and keeps the water storage tank 6 within the predetermined water level range. It is something to do.

When the sterilization mode A in step S200 is completed and the preparatory operation of the sauna device is completed, the process shifts to the start-up mode (step S300), which is the normal operation of the sauna device.
In this start-up mode, the blower fan 35 is set to strong operation to start driving the blower fan 35, the air heater 43 attached to the air supply port 36 is energized, and water is further stored in the water storage tank 6. By switching the energization ON / OFF state of the heating heater 9 with the switching means 65 so that the hot water temperature is kept higher than the set temperature set by the room temperature setting switch 55, the air in the sauna room 2 is made by the air heater 43. The blower fan 35 uses the blower fan 35 to crush the hot water in the water storage tank 6 that has been heated and heated to a temperature higher than the set temperature by the fine water droplets and the negative ion generator 1. The air is supplied from the air outlet 5 to the sauna room 2, and this is repeated in sequence to circulate the air in the sauna room 2 to promptly start up the inside of the sauna room 2.

(Explanation of startup mode)
Next, the operation of the above-mentioned start-up mode will be described with reference to the flowchart of FIG.

The control unit 64 sets the blower fan 35 to strong operation, starts driving the blower fan 35, energizes the air heater 43 (step S301), and the hot water temperature in the water storage tank 6 detected by the water storage temperature sensor 44 is 46. When the temperature drops below ° C, the energization of the heater 9 is switched to the ON state, and when the hot water temperature in the water storage tank 6 detected by the water storage temperature sensor 44 becomes 48 ° C or higher, the energization of the heater 9 is switched to the OFF state. In addition, the switching means 65 switches the energization ON / OFF state of the heating heater 9 so that the hot water temperature of the water storage tank 6 is kept at a temperature higher than the set temperature by a predetermined temperature (step S302).

After step S302, when the control unit 64 determines that the detection temperature detected by the room temperature sensor 46 provided in the upper part of the sauna room 2 has reached the set temperature (YES in step S303), the control unit 64 lights the bath lamp 60 of the remote control 52. At the same time, the speaker 61 notifies that the sauna room 2 has a usage atmosphere of a low temperature sauna having a relative humidity of 90% or more at a set temperature and can enter the room (step S304), and the start-up mode is terminated.

Even if the amount of hot water in the water storage tank 6 decreases during this start-up mode, the control unit 64 opens and closes the water supply valve 8 based on the detection signal from the water level detecting means 39 (float switches 40 and 41). The water storage tank 6 is kept within a predetermined water level range by controlling the water level.

When the start-up mode of step S300 is completed, the mode transitions to a stable mode (step S400) as a normal operation in which the user can take a bath.
In this stable mode, the heating heater 9 is turned on / off based on the water storage temperature sensor 44 and the set temperature until the temperature detected by the room temperature sensor 46 reaches the set temperature set by the room temperature setting switch 55 of the remote control 52. By switching and turning off the heating heater 9 when the temperature detected by the room temperature sensor 46 reaches the set temperature, stable and comfortable bathing in the sauna at the set temperature can be performed in the sauna room 2.

(Explanation of stable mode)
Next, the operation of the stable mode will be described with reference to the flowchart of FIG.

The control unit 64 turns off the energization of the air heater 43 and starts counting a predetermined time (for example, 60 minutes) which is a continuous operation time (step S401).
The continuous operation time is counted when the temperature inside the sauna room 2 reaches the set temperature.

After step S401, the control unit 64 determines whether the normal operation mode selected by the mode selection switch 62 of the remote controller 52 is the standard mode (step S402), and if the selected mode is the standard mode, the standard mode is used. The mist motor 22 and the blower fan 35 are driven at the rotation speed set in the mode, and the heater 9 is switched ON / OFF based on the set temperature set by the remote controller 52 and the detection temperature by the water storage temperature sensor 44 ( Step S403).

If the normal operation mode selected by the mode selection switch 62 is a weak mode, the control unit 64 drives the mist motor 22 and the blower fan 35 at the rotation speed set in the weak mode, and sets them by the remote controller 52. ON / OFF switching of the heater 9 is performed based on the set temperature set and the temperature detected by the water storage temperature sensor 44 (step S404).

Contents of ON / OFF switching control of the heater 9 based on the rotation speed of the mist motor 22 and the blower fan 35 in the standard mode and the weak mode, and the set temperature set by the remote controller 52 and the detected temperature by the water storage temperature sensor 44. Will be described later.

After various controls were performed in the standard mode in step S403 or in the weak mode in step S404, the control unit 64 showed whether the room temperature detected by the room temperature sensor 46 was equal to or higher than the set temperature set by the remote control 52. If it is determined (step S405) and it is determined that the room temperature has exceeded the set temperature, the heater 9 is switched to the OFF state and the control of the heater 9 based on the set temperature and the water storage temperature detected by the water storage temperature sensor 44 is interrupted. (Step S406).
If the control unit 64 determines that the room temperature detected by the room temperature sensor 46 in step S405 is not equal to or higher than the set temperature, the process returns to step S402 to make a determination.

When the heating heater 9 is switched to the OFF state in step S406 and the control of the heating heater 9 based on the set temperature and the water storage temperature sensor 44 is interrupted, the room temperature detected by the room temperature sensor 46 is the predetermined temperature in the control unit 64 . It is determined whether the set temperature is -0.5 ° C or lower (step S407), and if it is determined that the room temperature is below the set temperature -0.5 ° C, the process proceeds to the next step and the room temperature is set temperature -0.5 ° C. If the temperature is not lower than the temperature, the determination in step S407 is repeated.

When it is determined in step S407 that the room temperature detected by the room temperature sensor 46 has become the set temperature −0.5 ° C. or lower, the control unit 64 determines whether the continuous operation time counting is completed (step S408), and continuously operates. When it is determined that the time count is completed, the speaker 61 notifies by voice that the continuous operation time has ended, the bath lamp 60 and the operation lamp 57 are turned off, the blower fan 35 is stopped (step S409), and the operation is automatically performed. The operation switch is turned off, the stable mode is terminated, and the normal operation is terminated.
If it is determined in step S408 that the continuous operation time counting has not been completed, the determination of step S402 is returned and the heating heater 9 is controlled based on the set temperature and the water storage temperature detected by the water storage temperature sensor 44. resume.

Even if the amount of hot water in the water storage tank 6 decreases during this stable mode, the control unit 64 opens and closes the water supply valve 8 based on the detection signal from the water level detecting means 39 (float switches 40 and 41). By controlling, the water storage tank 6 is kept within a predetermined water level range.

When the stable mode ends in step S400 and the normal operation ends, the sterilization mode B (step S500), which is the end operation of the sauna device, is subsequently entered.
In this sterilization mode B, as a result of driving the blower fan 35 in normal operation to circulate the air in the sauna room 2, the hot water in the water storage tank 6 containing bacteria and the like is sterilized to a temperature that can be sterilized by the heater 9. By driving the mist motor 22 that rotates the rotating body 24 while heating, the hot water stored in the water storage tank 6 is sterilized, and the rotating body 24 that draws up the hot water heated from the water storage tank 6 by the hot water. , Dust, dust, bacteria, etc. adhering to the porous body 29 arranged on the outer periphery of the rotating body 24 and rotating together with the rotating body 24 and the air guide cylinder 31 arranged so as to cover the porous body 29 are washed away to make them clean. , The rotating body 24, the porous body 29, and the air guide cylinder 31 are sterilized and sterilized.

(Explanation of sterilization mode B)
Next, the operation of the above-mentioned sterilization mode B will be described with reference to FIG.
The control unit 64 determines whether or not the hot water temperature in the water storage tank 6 detected by the water storage temperature sensor 44 is a predetermined temperature (for example, 60 ° C. or higher) that can be sterilized (step S501), and the hot water temperature in the water storage tank 6 is set. When it is determined that the temperature is 60 ° C. or higher, the energization of the heating heater 9 is switched to the OFF state, and at the same time, the predetermined time for heating and sterilizing the water (hot water) in the water storage tank 6, that is, the counting of the sterilization time is started (step S502). ), When the hot water temperature in the water storage tank 6 detected by the water storage temperature sensor 44 becomes 58 ° C. or lower, the energization of the heating heater 9 is switched to the ON state, and the hot water temperature in the water storage tank 6 detected by the water storage temperature sensor 44 is changed. When the temperature reaches 60 ° C. or higher, the energization ON / OFF state of the heating heater 9 is switched by the switching means 65 so as to keep the hot water temperature of the water storage tank 6 at a sterilizable temperature, such as switching the energization of the heating heater 9 to the OFF state. It is switched (step S503), and the sterilization time, for example, the step S503 is repeated until the counting for 1 minute is completed (step S504).

Then, when it is determined that the counting of the sterilization time is completed (YES in step S504), the control unit 64 switches the energization of the heating heater 9 to the OFF state by the switching means 65 , and stops the driving of the mist motor 22 (YES). Step S505), it is determined whether 20 minutes, which is a predetermined time, has elapsed since the driving of the heater 9 and the mist motor 22 was stopped (step S506). If 20 minutes have passed since the counting of the sterilization time was completed, the drain valve 13 is opened to end the sterilization mode B (step S507), and if 20 minutes have not passed, the determination in step S506 is repeated.

When the sterilization mode B in step S500 is completed, the mode transitions to the drying mode (step S600).
In this drying mode, the blower fan 35 is started to be driven, the air heater 43 attached to the air supply port 36 is energized, and the ventilation fan 47 is further driven to suck fine water droplets and negative ion generator 1 and suction. The inside of the duct 4 and the inside of the sauna room 2 are dried.

(Explanation of drying mode)
Next, the operation of the above-mentioned drying mode will be described with reference to the flowchart of FIG.
The control unit 64 sets the blower fan 35 to strong operation, starts driving the blower fan 35, energizes the air heater 43, further drives the ventilation fan 47 (step S601), turns on the ventilation lamp 59, and turns on the ventilation lamp 59 in advance. It is determined whether or not the set drying time, for example, 90 minutes of counting has been completed (step S602), and when it is determined that the drying time has been completed, the drive of the blower fan 35 is stopped and the energization of the air heater 43 is turned off. Further, the driving of the ventilation fan 47 is stopped (step S603), the ventilation lamp 59 is turned off, the drying mode is terminated, the termination operation of the sauna device is terminated, and the sauna device is stopped.
The drain valve 13 remains open and the sauna device is stopped.

(Explanation of standard mode and weak mode)
Next, detailed control contents of the standard mode implemented in step S403 and the weak mode implemented in step S404 will be described.

First, the standard mode will be described. As shown in the flowchart of FIG. 14, the control unit 64 switches the heating heater 9 to the ON state, drives the mist motor 22 at 1200 rpm, and drives the blower fan 35 at 1180 rpm. The humidified air heated in the water storage tank 6 is blown into the sauna room 2 from the air outlet 5 to heat the inside of the sauna room 2 (step S701).

When the step S701 is completed, the control unit 64 compares the set temperature set by the room temperature setting switch 55 of the remote control 52 with the water storage temperature in the water storage tank 6 detected by the water storage temperature sensor 44, and the water storage temperature sensor 44. It is determined whether the stored water temperature detected in step 2 has reached the set temperature + 1 ° C or higher, which is the predetermined switching temperature obtained by adding a predetermined value to the set temperature (step S702), and if the stored water temperature has reached the set temperature + 1 ° C or higher. The heating heater 9 is switched to the OFF state (step S703), and if the stored water temperature is not equal to or higher than the set temperature + 1 ° C., the determination in step S702 is repeated.

When the step S703 is completed, the control unit 64 determines whether the water storage temperature detected by the water storage temperature sensor 44 has reached the set temperature of -1 ° C. or lower, which is a predetermined switching temperature obtained by adding a predetermined value to the set temperature. Step S704), if the water storage temperature is below the set temperature -1 ° C, the heater 9 is switched to the ON state (step S705), and if the water storage temperature is not below the set temperature -1 ° C, the determination in step S704 is made. repeat.
Then, when step S705 is completed, the process returns to step S702 and the determination is repeated.

The above determinations from step S701 to step S705 are repeated until the room temperature detected by the room temperature sensor 46 in step S405 becomes equal to or higher than the set temperature.

For example, if the set temperature is set to 40 ° C. by the room temperature setting switch 55, the heater 9 is switched to the ON state when the temperature detected by the water storage temperature sensor 44 becomes 39 ° C. or lower, and when the temperature reaches 41 ° C. or higher. By switching the heating heater 9 to the OFF state, the warm humidified air heated from the air outlet 5 can be blown into the sauna room 2, and the inside of the sauna room 2 can be kept near the set temperature.

In addition, since the amount of humidified air blown into the sauna room 2 is larger in the standard mode than in the weak mode, the inside of the sauna room 2 is filled with a large amount of negative ions and mist, so that the user can fully enjoy the sauna bath. can.

Next, the weak mode will be described. As shown in the flowchart of FIG. 15, the control unit 64 switches the heating heater 9 to the ON state, drives the mist motor 22 at 800 rpm, and drives the blower fan 35 at 800 rpm. The humidified air heated in the water storage tank 6 is blown into the sauna room 2 from the air outlet 5 to heat the inside of the sauna room 2 (step S801).

When the step S801 is completed, the control unit 64 compares the set temperature set by the room temperature setting switch 55 of the remote control 52 with the water storage temperature in the water storage tank 6 detected by the water storage temperature sensor 44, and the water storage temperature sensor 44. It is determined whether the stored water temperature detected in step 2 is the set temperature + 3 ° C or higher, which is the predetermined switching temperature obtained by adding the predetermined value to the set temperature (step S802), and if the stored water temperature is the set temperature + 3 ° C or higher. The heater 9 is switched to the OFF state (step S803), and if the stored water temperature is not equal to or higher than the set temperature + 3 ° C., the determination in step S802 is repeated.

When the step S803 is completed, the control unit 64 determines whether the water storage temperature detected by the water storage temperature sensor 44 has become the set temperature + 1 ° C. or less, which is a predetermined switching temperature obtained by adding a predetermined value to the set temperature (step). S804) If the water storage temperature is below the set temperature + 1 ° C, the heater 9 is switched to the ON state (step S805), and if the water storage temperature is not below the set temperature + 1 ° C, the determination in step S804 is repeated.
Then, when step S805 is completed, the process returns to step S802 and the determination is repeated.

The determination from step S801 to step S805 is repeated until the room temperature detected by the room temperature sensor 46 in step S405 becomes equal to or higher than the set temperature.

For example, if the set temperature is set to 40 ° C. by the room temperature setting switch 55, the heating heater 9 is switched to the ON state when the temperature detected by the water storage temperature sensor 44 becomes 41 ° C. or lower, and when the temperature reaches 43 ° C. or higher. By switching the heating heater 9 to the OFF state, humidified air having a temperature higher than that in the standard mode setting can be blown into the sauna room 2 from the air outlet 5 to keep the inside of the sauna room 2 near the set temperature.

Further, in the weak mode, since the rotation speeds of the mist motor 22 and the blower fan 35 are lower than those in the standard mode, the noise is higher than in the standard mode, so that the user can enjoy the sauna bath in the quiet sauna room 2 in the sauna bath. can.

Next, the effect of the present invention will be described.

When the weak mode is set in the stable mode in which the sauna bath can be performed, a heater based on the water storage temperature and the set temperature detected by the water storage temperature sensor 44 until the room temperature detected by the room temperature sensor 46 reaches the set temperature. The ON / OFF switching temperature of 9 was set higher than when the standard mode was set, and the temperature of the humidified air blown from the air outlet 5 into the sauna room 2 was higher than when the standard mode was set. Due to the low rotation speed of the blower fan 35 and the small amount of humidified air blown from the blower port 5, even if the ability to raise the inside of the sauna room 2 to the set temperature is inferior to the standard mode, the air is blown from the blower port 5. Since the temperature rise of the humidified air is higher than the standard mode, the temperature rise efficiency in the sauna room 2 can be improved. Therefore, when the weak mode is set, the door 48 of the sauna room 2 is opened and closed, and the temperature inside the sauna room 2 drops. , It is possible to suppress the time required to return to the vicinity of the set temperature to be significantly longer than when the standard mode is set, and the user who takes a sauna bath can use the sauna in the sauna room 2 for a long time at a temperature below the set temperature. It is possible to suppress the feeling of discomfort by taking a bath.

Further, when the room temperature detected by the room temperature sensor 46 becomes the set temperature or higher during the stable mode, the heater 9 is switched to the OFF state, and when the room temperature detected by the room temperature sensor 46 becomes the set room temperature −0.5 ° C. or lower, the heating heater 9 is switched to the OFF state. Since the ON / OFF state of the heater 9 is switched by comparing the water storage temperature detected by the water storage temperature sensor 44 with the predetermined switching temperature, the room temperature in the sauna room 2 greatly deviates from the set temperature when the sauna bath is performed. Since it is possible to prevent the room temperature from returning to the set temperature for a long time, it is possible to prevent the comfort of the sauna bath from being lowered.

Further, the predetermined switching temperature is a temperature obtained by adding a predetermined value to the set temperature, and the predetermined value is set to be larger in the weak mode than in the standard mode, so that the humidified air blown into the sauna room 2 is charged. The temperature changes reliably according to the set temperature, and the temperature of the humidified air blown in the weak mode is higher than in the standard mode. Therefore, after the room temperature drops by opening and closing the door 48 of the sauna room 2, Since it is possible to prevent the time for the room temperature to return to be long, it is possible to suppress the discomfort caused by the user taking a sauna bath in a state where the room temperature is low for a long time.

When the weak mode is set, the humidified air with a higher temperature is blown from the blower port 5 than when the standard mode is set, but the rotation speed of the blower fan 35 is lower than when the standard mode is set, and the humidified air blown from the blower port 5 is blown. Even if the humidified air blown from the air outlet 5 touches the user's feet while the user is taking a sauna bath in the sauna room 2, the momentum of the humidified air is weak and the heat is high. Since the experience is almost the same as when the standard mode is set, the inside of the sauna room 2 can be returned to near the set temperature at an early stage without impairing the user's comfort in the sauna bath.

Further, in the present invention, the rotation speeds of the mist motor 22 and the blower fan 35 when the weak mode is set are lower than those when the standard mode is set, so that the noise generated from the mist motor 22 and the blower fan 35 when the weak mode is set. The value is lower than when the standard mode is set, and the user can enjoy the sauna bath in a quiet space.

The rotation speed of the mist motor 22 and the blower fan 35 and the ON / OFF switching temperature of the heating heater 9 at the time of setting the standard mode and the weak mode used in the description of the embodiment of the present invention are examples. Changes in each rotation speed and switching temperature within the range are within the scope of the present invention.
