However, in this conventional type, when it is possible to set a weak mode that lowers the rotation speed of the blower fan during normal operation from the conventional set value for the purpose of enhancing quietness in normal operation, the weak mode is set. Then, the amount of humidified air supplied to the sauna room during normal operation decreases, so after the user enters the sauna room and opens and closes the door while the weak mode is set, the temperature inside the sauna room decreases. Since the time for the temperature in the sauna room to return to the set temperature is longer than in the past, the user may feel uncomfortable for a long time in the sauna bath below the set temperature, and there is room for improvement. was there.

In order to solve the above problems, in claim 1 of the present invention, a sauna room provided with an openable and closable door,
A water storage tank for storing water,
A heater installed in the water of the water storage tank and capable of switching the ON/OFF state,
Humidified air generating means having the water storage tank and the heater,
A blower fan with variable rotation speed that blows the humidified air generated by the humidified air generating means into the sauna chamber from a blower opening,
A stored water temperature sensor for detecting the stored water temperature in the water storage tank;
A controller that compares the stored water temperature detected by the stored water temperature sensor with a predetermined switching temperature during the normal operation and switches the ON/OFF state of the heater.
In the normal operation, a standard mode and a weak mode in which the rotation speed of the blower fan is set lower than the standard mode can be set,
The control unit is characterized in that, when the weak mode is set, the predetermined switching temperature is set higher than that in the standard mode.

Further, a room temperature setting means for setting a desired room temperature of the sauna room,
A room temperature sensor for detecting 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 during the normal operation, the controller switches the heating heater to the OFF state and the room temperature sensor detects the temperature. When the room temperature becomes equal to or lower than a predetermined temperature lower than the desired room temperature set by the room temperature setting means, the stored water temperature detected by the stored water temperature sensor is compared with the predetermined switching temperature to turn on/off the heater. It is characterized by switching.

Further, the predetermined switching temperature is a temperature obtained by adding a predetermined value to a desired room temperature set by the room temperature setting means, and the predetermined value is set to be higher in the weak mode than in the standard mode. Is characterized by.

According to the present invention, when the weak mode, in which the rotation speed of the blower fan is lower than that in the standard mode during normal operation, is set, the predetermined switching temperature is set higher than in the standard mode, so that the temperature of the humidified air blown from the blower opening is in the standard mode. Compared with the above, the weak mode is higher, so it is possible to prevent the time for the room temperature to recover after opening and closing the door of the sauna room, so it is possible to prevent the time from increasing. It is possible to suppress the discomfort caused by the user having a sauna bath while the temperature of the transit room is low.

Further, 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 heater is turned off 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 stored water temperature detected by the stored water temperature sensor is compared with a predetermined switching temperature to switch the ON/OFF state of the heater. Since it is possible to prevent the room temperature from returning to the desired room temperature for a long time without deviating from the room temperature, it is possible to suppress deterioration in comfort of the sauna bath.

Further, 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 since the predetermined value is set to be higher in the weak mode than in the standard mode, the air is blown into the sauna room. The temperature of the humidified air that changes is surely changed according to the desired room temperature, and the temperature of the humidified air that is blown in the weak mode is higher than in the standard mode. Since it is possible to prevent the time for the room temperature to recover 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. ..

In this cleaning mode, the drain valve 13 that opens and closes the drain pipe 12 that drains the water or hot water in the water storage tank 6 is opened, and the water supply valve 8 that opens and closes the water supply pipe 7 that supplies water into the water storage tank 6 is opened. This valve is used to supply water into the water storage tank 6 to wash and discharge dust, dust, germs and the like remaining on the bottom of the water storage tank 6 before storing water in the water storage tank 6.

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

The control unit 62 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. The process of step S102 is repeated while it is determined that it is not present, and when it is determined that the float switch 40 has output the OFF signal, the water supply valve 8 is opened after a certain time delay (step S103).

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

When the cleaning mode of step S100 is completed, the mode is subsequently changed to the disinfection mode A (step S200).
In the sterilization mode A, the heater 9 arranged near the bottom of the water storage tank 6 is turned on by the switching means 63 to heat the water in the water storage tank 6 to a temperature at which it can be sterilized, and the rotor is rotated. The mist motor 22 that rotates 24 is driven to sterilize the water stored in the water storage tank 6, and the rotation body 24 that pumps hot water heated from the water storage tank 6 and the rotation body 24 that is arranged on the outer periphery of the rotation body 24 are rotated. Dust, dust, bacteria, etc. adhering to the porous body 29 rotating with the body 24 and the air guide cylinder 31 arranged so as to cover the porous body 29 are washed away to make it a clean state. It is for sterilizing and sterilizing the cylinder 31.

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

The control unit 62 determines whether or not the float switch 40 for detecting the low water level has output an ON signal (step S201), and when determining that the float switch 40 has output an ON signal, heats the water in the water storage tank 6. The energization of the heater 9 is turned on by the switching means 63, the driving 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 equal to or higher than a predetermined sterilizable value (for example, 60° C.) (step S203).

When it is determined in step S203 that the temperature of the hot water in the water storage tank 6 is 60° C. or higher, the control unit 62 turns off the power supply to the heater 9 by the switching unit 63 and simultaneously heats the water in the water storage tank 6. A predetermined time for sterilization, that is, the count of the sterilization time is started (step S204).

After the step S204, the controller 62 turns on the energization of the heater 9 when the temperature of the hot water in the water storage tank 6 detected by the water storage temperature sensor 44 becomes 58° C. or less, and the water storage temperature sensor 44 detects the water storage. When the temperature of the hot water in the tank 6 becomes 60° C. or higher, the heater 9 is turned on by the switching means 63 so as to keep the hot water temperature of the water storage tank 6 at the sterilizable temperature by turning off the power supply to the heater 9. The ON/OFF state is switched (step S205), and the step S205 is repeated until the count of 1 minute, which is the sterilization time, is completed (step S206).

When the control unit 62 determines that the count of the sterilization time is finished (YES in step S206), the heater 9 is turned off (step S207), the sterilization mode A is finished, and the sauna apparatus is operated. The preparatory operation is completed.

When 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 62 transmits a signal to switch the energization of the heater 9 to the ON state by the switching unit 63, and then a predetermined value. It is determined whether 30 minutes, which is the time, has elapsed (step S208), and if it is determined that 30 minutes have passed since the signal was sent to switch the energization to the heater 9 to the ON state, the drain valve 13 is opened and the water tank. The water in 6 is drained, the switching means 63 has a short-circuit fault, and the speaker 61 informs by voice that it is impossible to switch the ON/OFF state of energization to the heater 9 (step S209), and the sauna. Stop the preparatory operation of the equipment and do not proceed to the next step.

If 30 minutes have not elapsed since 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.

After the float switch 40 outputs the ON signal in step S201, when the water supply is continued and the high water level detecting float switch 41 outputs the ON signal, the control unit 62 closes the water supply valve 8 to supply the water. The control unit 62 controls the water supply valve 8 to supply water based on the detection signal from the water level detection means 39 (float switches 40 and 41), and keeps the water tank 6 within the predetermined water level range. It is something to do.

When the disinfection mode A of the step S200 ends and the preparatory operation of the sauna apparatus ends, then the startup mode (step S300) that is the normal operation of the sauna apparatus is transitioned to.
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 stored in the water storage tank 6. By switching the energization ON/OFF state of the heating heater 9 by the switching means 63 so as to keep the hot water temperature which is higher than the set temperature set by the room temperature setting switch 55, the air in the sauna room 2 is set by the air heater 43. The fine water droplets and negative ions generated by crushing the hot water in the water storage tank 6 which has been heated and heated to a temperature higher than the set temperature by the fine water droplet and negative ion generator 1 are blown by the blower fan 35. Air is supplied from the blower port 5 to the sauna room 2, and this is repeated sequentially to circulate the air in the sauna room 2 to quickly start up the inside of the sauna room 2.

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

The controller 62 sets the blower fan 35 to a strong operation to start driving the blower fan 35 and 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 falls below ℃, the heater 9 is turned on, and when the temperature of the hot water in the water tank 6 detected by the water temperature sensor 44 reaches 48°C, the heater 9 is turned off. First, the switching means 63 switches the energization ON/OFF state of the heater 9 so that the hot water temperature of the water storage tank 6 is maintained at a temperature higher than the set temperature by a predetermined temperature (step S302).

After step S302, when the control unit 62 determines that the 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 bath lamp 60 of the remote controller 52 is turned on. At the same time, the speaker 61 informs that the sauna room 2 is in the use atmosphere of the low temperature sauna having a relative humidity of 90% or more at the set temperature and can be entered (step S304), and the startup mode is ended.

Even when the hot water in the water storage tank 6 decreases during the start-up mode, the control unit 62 opens and closes the water supply valve 8 based on the detection signal from the water level detection means 39 (float switches 40 and 41). The water storage tank 6 is kept within a predetermined water level range by controlling the above.

When the start-up mode in step S300 is completed, the system then transitions to a stable mode (step S400) as normal operation in which the user can bathe.
In this stable mode, the heater 9 is turned on/off based on the stored water 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 controller 52. When the temperature detected by the room temperature sensor 46 is switched and the temperature reaches the set temperature, the heater 9 is turned off to enable stable and comfortable sauna bathing at the set temperature in the sauna room 2.

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

The control unit 62 turns off the power supply to the air heater 43 and starts counting a preset predetermined time (for example, 60 minutes) which is a continuous operation time (step S401).
The continuous operation time starts counting when the temperature inside the sauna room 2 reaches the set temperature.

After step S401, the control unit 62 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 selected. The mist motor 22 and the blower fan 35 are driven at the number of rotations set in the mode, and ON/OFF of the heater 9 is switched based on the set temperature set by the remote controller 52 and the temperature detected by the stored water temperature sensor 44 ( Step S403).

When the normal operation mode selected by the mode selection switch 62 is the weak mode, the control unit 62 drives the mist motor 22 and the blower fan 35 at the rotation speed set in the weak mode, and sets the remote controller 52. The heater 9 is turned on/off based on the set temperature and the temperature detected by the stored water temperature sensor 44 (step S404).

Details of ON/OFF switching control of the heating heater 9 based on the rotation speeds 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 temperature detected by the stored water temperature sensor 44. Will be described later.

After performing various controls in the standard mode in step S403 or in the weak mode in step S404, the control unit 62 determines whether the room temperature detected by the room temperature sensor 46 is equal to or higher than the set temperature set by the remote controller 52. When it is determined (step S405) that the room temperature is equal to or higher than 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 stored water temperature detected by the stored water temperature sensor 44 is interrupted. Yes (step S406).
If the control unit 62 determines in step S405 that the room temperature detected by the room temperature sensor 46 is not higher than the set temperature, the process returns to step S402 to make a determination.

When the heating heater 9 is turned off in step S406 and the control of the heating heater 9 based on the set temperature and the stored water temperature sensor 44 is interrupted, the control unit 62 causes the room temperature detected by the room temperature sensor 46 to be the predetermined temperature. It is determined whether or not the temperature is lower than or equal to the set temperature −0.5° C. (step S407), and when it is determined that the room temperature is equal to or lower than the set temperature −0.5° C., the process proceeds to the next step, where the room temperature is equal to or lower than the set temperature −0.5. If the temperature is not lower than °C, 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 equal to or lower than the set temperature −0.5° C., the control unit 62 determines whether or not the counting of the continuous operation time is completed (step S408), and the continuous operation is performed. When it is determined that the time count has ended, the speaker 61 notifies the end of the continuous operation time by voice, turns off the bathing lamp 60 and the operation lamp 57, and stops the blower fan 35 (step S409), and automatically. Then, the operation switch is turned off, the stable mode ends, and the normal operation ends.
If it is determined in step S408 that the continuous operation time has not been counted, the process returns to the determination in step S402, and the heater 9 is controlled based on the set temperature and the stored water temperature detected by the stored water temperature sensor 44. To resume.

Even when the hot water in the water storage tank 6 decreases during this stable mode, the control unit 62 opens and closes the water supply valve 8 based on the detection signal from the water level detection means 39 (float switches 40 and 41). By controlling, the water storage tank 6 is kept within the predetermined water level range.

When the stable mode ends and the normal operation ends in step S400, a transition is made to the disinfection mode B (step S500), which is the end operation of the sauna device.
In this sterilization mode B, the blower fan 35 is driven in normal operation to circulate the air in the sauna room 2, and as a result, the warm water in the water storage tank 6 containing bacteria and the like is heated to a temperature at which it can be sterilized by the heater 9. By driving the mist motor 22 that heats and rotates the rotary body 24, the hot water stored in the water storage tank 6 is sterilized, and the hot water heated from the water storage tank 6 is pumped up by the hot water. , A porous body 29 arranged on the outer periphery of the rotating body 24 and rotating together with the rotating body 24, and a dust, dust, bacteria, etc. adhering to the air guide cylinder 31 arranged so as to cover the porous body 29 are washed away to make it a clean state. The rotator 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 disinfection mode B will be described with reference to the flowchart of FIG.
The controller 62 determines whether or not the temperature of the hot water in the water storage tank 6 detected by the water storage temperature sensor 44 is a sterilizable predetermined temperature (for example, 60° C. or higher) (step S501), and the hot water temperature in the water storage tank 6 is determined. If it is determined that the temperature is 60° C. or higher, the energization of the heater 9 is switched to the OFF state, and at the same time, the counting of the predetermined time for heat sterilizing the water (warm water) in the water storage tank 6, that is, the disinfection 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 power to the 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 becomes When the temperature exceeds 60° C., the energization of the heater 9 is switched to the OFF state, and the energization ON/OFF state of the heater 9 is switched by the switching means 63 so as to keep the hot water temperature of the water storage tank 6 at the sterilizable temperature. After switching (step S503), the step S503 is repeated until the sterilization time, for example, the count of 1 minute is completed (step S504).

Then, when it is determined that the count of the sterilization time has ended (YES in step S504), the control unit 62 switches the energization of the heater 9 to the OFF state by the switching unit 63 and stops the driving of the mist motor 22 ( In 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 end of counting the disinfection time, the drain valve 13 is opened to end the disinfection mode B (step S507), and if 20 minutes have not elapsed, the determination in step S506 is repeated.

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

(Explanation of drying mode)
Next, the operation of the above drying mode will be described with reference to the flowchart of FIG.
The control unit 62 sets the blower fan 35 to the strong operation, starts driving the blower fan 35, energizes the air heater 43, further drives the ventilation fan 47 (step S601), and turns on the ventilation lamp 59 in advance. It is determined whether or not the set drying time, for example, 90 minutes has been counted (step S602), and when it is determined that the drying time is finished, the driving of the blower fan 35 is stopped and the energization of the air heater 43 is turned off. Further, the drive of the ventilation fan 47 is stopped (step S603), the ventilation lamp 59 is turned off, the drying mode is ended, the ending operation of the sauna apparatus is ended, and the sauna apparatus is stopped.
The sauna device is in a stopped state while the drain valve 13 is open.

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

First, the standard mode will be described. As shown in the flowchart of FIG. 14, the control unit 62 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 blower opening 5 to heat the inside of the sauna room 2 (step S701).

When the step S701 is completed, the control unit 62 compares the set temperature set by the room temperature setting switch 55 of the remote controller 52 with the stored water temperature in the storage tank 6 detected by the stored water temperature sensor 44, and the stored water temperature sensor 44. It is judged whether or not the stored water temperature detected in step S1 is equal to or higher than a set temperature +1°C which is a predetermined switching temperature obtained by adding a predetermined value to the set temperature (step S702). The heater 9 is switched to the OFF state (step S703), and if the stored water temperature is not higher than the set temperature +1°C, the determination of step S702 is repeated.

Upon completion of step S703, the control unit 62 determines whether the stored water temperature detected by the stored water temperature sensor 44 is equal to or lower than a set temperature -1°C which is a predetermined switching temperature obtained by adding a predetermined value to the set temperature ( Step S704), if the stored water temperature is below the set temperature-1°C, the heater 9 is switched to the ON state (step S705), and if the stored water temperature is below the set temperature-1°C, the judgment of step S704 is made. repeat.
Then, when step S705 is completed, the process returns to step S702 to repeat the determination.

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, when the temperature detected by the stored water temperature sensor 44 becomes 39° C. or lower, the heater 9 is switched to the ON state, and when it becomes 41° C. or higher. By switching the heater 9 to the OFF state, the warm humidified air heated from the blower opening 5 can be blown into the sauna room 2 and the inside of the sauna room 2 can be maintained near the set temperature.

Further, in the standard mode, the amount of humidified air blown into the sauna room 2 is larger than that in the weak mode, so 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. it can.

Next, the weak mode will be described. As shown in the flowchart of FIG. 15, the control unit 62 switches the 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 blower opening 5 to heat the inside of the sauna room 2 (step S801).

Upon completion of step S801, the control unit 62 compares the set temperature set by the room temperature setting switch 55 of the remote controller 52 with the stored water temperature in the storage tank 6 detected by the stored water temperature sensor 44, and the stored water temperature sensor 44. It is judged whether or not the stored water temperature detected at is equal to or higher than a set temperature +3°C which is a predetermined switching temperature obtained by adding a predetermined value to the set temperature (step S802), and if the stored water temperature is equal to or higher than the set temperature +3°C. The heater 9 is switched to the OFF state (step S803), and if the stored water temperature is not higher than the set temperature +3° C., the determination of step S802 is repeated.

Upon completion of step S803, the control unit 62 determines whether the stored water temperature detected by the stored water temperature sensor 44 is equal to or lower than a set temperature +1° C. which is a predetermined switching temperature obtained by adding a predetermined value to the set temperature (step S803). S804), if the stored water temperature is equal to or lower than the set temperature +1°C, the heater 9 is switched to the ON state (step S805), and if the stored water temperature is not equal to or lower than 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 above determinations from step S801 to step S805 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 stored water temperature sensor 44 becomes 41° C. or lower, and when it becomes 43° C. or higher. By switching the 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 and the inside of the sauna room 2 can be maintained near the set temperature.

Further, in the weak mode, the mist motor 22 and the blower fan 35 have lower rotational speeds than the standard mode, and therefore, the silent mode is higher than the standard mode, so that the user can enjoy the sauna bath in the quiet sauna room 2 in the sauna bath. it 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, the heater based on the stored water temperature detected by the stored water temperature sensor 44 and the set temperature until the room temperature detected by the room temperature sensor 46 reaches the set temperature. The ON/OFF switching temperature of 9 is set higher than that in the standard mode setting, and the temperature of the humidified air blown into the sauna room 2 from the blower opening 5 is set higher than that in the standard mode setting. Since the rotation speed of the blower fan 35 is low and the amount of humidified air blown from the blower port 5 is small, even if the ability to raise the temperature inside the sauna room 2 to the set temperature is inferior to the standard mode, it is blown from the blower port 5. Since the temperature of the humidified air is higher than that in the standard mode, the temperature rising 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 in the sauna room 2 decreases. , It is possible to prevent the time to return to near the set temperature from becoming significantly longer than that when the standard mode is set, and a user who takes a sauna bath in the sauna room 2 for a long time can keep the temperature below the set temperature. It is possible to suppress feeling uncomfortable by taking a bath.

Further, when the room temperature detected by the room temperature sensor 46 becomes equal to or higher than the set temperature 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 equal to or lower than the set room temperature −0.5° C., Since the ON/OFF state of the heater 9 is switched by comparing the stored water temperature detected by the stored water temperature sensor 44 with a predetermined switching temperature, the room temperature in the sauna room 2 largely deviates from the set temperature when the sauna bath is performed. Since it is possible to prevent the indoor temperature from returning to the set temperature for a long time, it is possible to suppress deterioration in comfort of the sauna bath.

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 Since the temperature surely changes according to the set temperature and the temperature of the humidified air to be blown is higher in the weak mode than in the standard mode, after the door temperature of the sauna room 2 is opened/closed, the room temperature decreases, Since it is possible to prevent the time when the room temperature is restored from increasing, it is possible to suppress the discomfort caused by the user performing the sauna bath while the room temperature is low for a long time.

It should be noted that when the weak mode is set, hotter humidified air is blown from the blower port 5 than in the standard mode, but the rotation speed of the blower fan 35 is lower than that in the standard mode, and the humidified air blown from the blower port 5 is sent. Since the user's momentum is weak, when the user is performing a sauna bath in the sauna room 2, even if the humidified air blown from the blower opening 5 touches the feet of the user, the force of the humidified air is weak and the Since the sensation is almost the same as when the standard mode is set, the inside of the sauna room 2 can be quickly returned to around the set temperature without impairing the comfort of the user in the sauna bath.

Further, in the present invention, since the rotation speeds of the mist motor 22 and the blower fan 35 in the weak mode setting are lower than those in the standard mode setting, the noise generated from the mist motor 22 and the blower fan 35 in the weak mode setting. 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 speeds of the mist motor 22 and the blower fan 35 and the ON/OFF switching temperatures of the heater 9 used in the description of the embodiments of the present invention at the time of setting the standard mode and the weak mode are examples, and are included in the spirit of the present invention. The change of each rotation speed and the switching temperature within the range along the range is within the scope of the present invention.
