When the sauna operation is started, the control means 61 first detects the room temperature of the sauna room 2 before the sauna operation is started by using the room temperature sensor 46, and this is used instead of the outside air temperature. When the initial room temperature is detected and the initial room temperature is 20 ° C. or more of the reference temperature, the detected temperature is hardly affected by the outside air temperature. Therefore, the detected temperature of the room temperature sensor 46 is used as it is as the control temperature without correction. However, if the initial room temperature is less than the reference temperature of 20 ° C., the outside temperature is low and the detection temperature of the room temperature sensor 46 is affected, so the control temperature is corrected to the lower one. By controlling, even if it does not reach the set temperature, it is controlled that it has been reached, and the sauna room 2 is prevented from reaching a room temperature higher than the set temperature.

Next, the operation of one embodiment of this sauna device will be described with reference to the flowcharts of FIGS.
When the set temperature of the sauna room 2, for example, 42 ° C. is set by the room temperature setting switch 55 of the remote controller 52 provided on the side wall of the sauna room 2, and the operation switch 56 is turned ON in step S11, the process proceeds to step S12 and the control means 61 Detects the initial room temperature by the room temperature sensor 46, and first determines whether the initial room temperature is 20 ° C. or more. If YES, the process proceeds to step S13, and the set temperature of 42 ° C. is determined as the control temperature as it is, and step S12. In the case of NO, the process proceeds to step S14, this time it is determined whether it is less than 20 ° C., and if YES, the process proceeds to step S15 and the control temperature is corrected to the lower one. That is, when the outside air temperature is low, the rotation motor 22, the blower 35, and the empty By controlling the heater 43, the inside of the sauna room 2 is maintained at the set temperature of 42 ° C., and the inside of the sauna room 2 can be reliably maintained at the set temperature even when the outside air temperature is low. This is the initial setting mode (step S10) performed at the beginning of all modes.

  Next, the initial setting mode (step 10) is finished, the operation of the sauna device is started, and the cleaning mode, which is a preparation operation of the sauna device, is started (step S100). In this cleaning mode, the automatic drain valve 13 that opens and closes the drain pipe 12 that drains the water in the water reservoir 6 or the hot water is opened, and the automatic water valve 8 that opens and closes the water pipe 7 that feeds water into the water reservoir 6. Is opened, water is supplied into the water storage unit 6, and before the water is stored in the water storage unit 6, dust, dust, bacteria, etc. remaining on the bottom of the water storage unit 6 are washed and drained. .

  Next, the operation of the above-described cleaning mode will be described with reference to the flowchart of FIG. 9. First, the control means 61 opens the automatic drain valve 13 (step S101), and whether the low water level detection float switch 40 is OFF. (Step S102), the process of Step S102 is repeated while it is determined that the float switch 40 is not OFF. If it is determined that the float switch 40 is OFF, automatic water supply is performed after a delay of a predetermined time. The valve 8 is opened (step S103). When the automatic water supply valve 8 is opened in step S103 and water supply into the water storage section 6 is started, it is subsequently determined whether or not a predetermined time has elapsed (step S104), and if it is determined that the predetermined time has elapsed, The automatic drain valve 13 is closed (step S105), and the cleaning mode is terminated.

  In the cleaning mode described above, the control means 61 opens the automatic drain valve 13 and also opens the automatic water supply valve 8 so as to supply water to the water storage section 6 and wash the water storage section 6. Water is supplied with the automatic drain valve 13 opened, and dust, dust, bacteria, etc. remaining on the bottom of the water storage section 6 can be reliably washed and drained before storing water in the water storage section 6. When the operation is started and the user takes a bath in the sauna, clean water is stored in the water storage section 6, so that the sauna bath can be performed safely and safely.

  Further, when the control means 61 determines in step S102 that the float switch 40 is not OFF, that is, when it receives a detection signal from the low water level detection float sensor 40, the processing of step S102 is performed. Repeatedly, the automatic water supply valve 8 is not opened and the water storage unit 6 is not supplied with water, so that the drained water is not discharged for some reason after the last sauna operation stop, and the previously used dirty water is stored in the water storage unit 6 as it is If the float switch 40 is determined to be OFF, that is, if the detection signal from the float switch 40 is not received, the dirty water in the water storage section 6 can be drained reliably. Since the automatic water supply valve 8 is opened after the time delay, the water stored in the water storage section 6 is completely drained before water supply. Dust, dust, germs, etc. remaining on the bottom of the water storage section 6 can be reliably washed and drained, and when the sauna operation starts and the user bathes in the sauna, the water storage section 6 stores clean water. So you can take a safe and safe sauna bath.

  When the cleaning mode in step S100 is completed, the process proceeds to the sterilization mode A (step S200). In this sterilization mode A, the heater 9 disposed near the inner bottom of the water storage unit 6 is energized. The water in the water storage unit 6 is heated to a temperature at which the water can be sterilized, and the rotating motor 22 that rotates the rotating body 24 is driven to sterilize the water stored in the water storage unit 6. Dust and dust adhering to the rotating body 24 that pumps up the heated hot water, the porous body 29 that is arranged on the outer periphery of the rotating body 24 and rotates together with the rotating body 24, and the air guide cylinder 31 that is arranged so as to cover the porous body 29 The rotator 24, the porous body 29, and the air guide tube 31 are sterilized and sterilized by washing away bacteria and the like.

  Next, the operation of the sterilization mode A will be described with reference to the flowchart of FIG. 9. First, the control means 61 determines whether or not the low water level detection float switch 40 is ON (step S201). If it is determined that the switch 40 is ON, the heater 9 that heats the water in the water storage unit 6 is energized and the drive of the rotating motor 22 that rotates the rotating body 24 is started (step S202). It is determined whether or not the temperature of the hot water in the water storage unit 6 detected at 44 is a predetermined temperature that can be sterilized, for example, 60 ° C. or higher (step S203).

  If it is determined in step S203 that the temperature of the hot water in the water storage unit 6 is 60 ° C. or higher, the energization to the heater 9 is turned off and at the same time the water (warm water) in the water storage unit 6 is heated and sterilized. That is, counting of the sterilization time is started (step S204), and when the hot water temperature in the water storage section 6 detected by the water storage temperature sensor 44 becomes 58 ° C. or less, the heater 9 is energized again, and the water storage temperature sensor 44 When the temperature of the hot water in the water storage unit 6 to be detected becomes 60 ° C. or higher, the heater 9 is set so as to keep the temperature of the hot water in the water storage unit 6 at a sterilizable temperature so that the power supply to the heater 9 is turned off again. The ON / OFF control is performed (step S205), and the step S205 is repeated until the sterilization time, for example, 1 minute count is completed (step S206). If it is determined that the sterilization time has been counted (YES in step S206), the heater 9 is turned off (step S207), the sterilization mode A is terminated, and the preparation operation of the sauna apparatus is terminated. It is.

  When the water supply is continued and the high water level detection float switch 41 is turned on after the float switch 40 is turned on in step S201, the control means 61 closes the automatic water supply valve 8 and terminates the water supply. Yes, the control means 61 controls the automatic water supply valve 8 to supply water based on the detection signal from the water level detection means 39 (float switches 40, 41) so as to keep the water storage section 6 within a predetermined water level range. Is.

  In the sterilization mode A described above, the heater 9 is energized to heat the water in the water storage section 6 to a sterilizable temperature and maintain the temperature for a predetermined time, and the rotation motor 22 that rotates the rotating body 24 is driven. Therefore, after the last use of the sauna apparatus, even if the sauna apparatus is in a stopped state with bacteria attached to the water storage section 6, the rotating body 24, the porous body 29, and the air guide tube 31, The hot water stored in the water storage unit 6 is agitated by the rotation of the body 24 and the temperature of the hot water in the water storage unit 6 is uniformly heated, so that the hot water in the water storage unit 6 can be uniformly sterilized by heating, The inner wall of the water storage unit 6 that is in contact with the hot water of the water storage unit 6 can also be sterilized by heating, and further, the rotating water 24 rotates so that the hot water in the water storage unit 6 heated to a sterilizable temperature is submerged. The lower end of the rotating body 24 A part of the hot water pumped up from the front and back surfaces of the rotating body 24 along the surface by centrifugal force is scattered from the plurality of pores 25 at the upper end of the rotating body 24 toward the outer periphery. Since it collides with the rotating porous body 29 and a part of other hot water passes through the porous portion 30 and hits the inner wall of the air guide tube 31 on the outer periphery of the porous body 29, the rotating body 24, the porous body 29, and the air guide Dust, dust, bacteria, etc. adhering to the cylinder 31 can be washed away to a clean state, and the rotating body 24, the porous body 29, and the air guide cylinder 31 can be sterilized and sterilized. The hot water sterilized inner wall of the water storage unit 6, the rotating body 24, the porous body 29, the air guide tube 31, and the clean hot water in the water storage unit 6 can be used for sauna operation, and the user can use the sauna safely and safely. Can do It is intended.

  When the sterilization mode A in step S200 is finished and the preparation operation of the sauna device is finished, the operation mode is subsequently changed to a startup mode (step S300) which is a sauna operation of the sauna device. 35 is set to a strong operation to start driving the blower 35, the air heater 43 attached to the air supply port 36 is energized, and the hot water temperature stored in the water storage unit 6 is set to the room temperature setting switch 55. By controlling the heater 9 to be ON / OFF so as to keep the temperature higher than the temperature set in step 1, the air in the sauna room 2 is heated by the air heater 43 and set by the fine water droplet and negative ion generator 1. The blower 35 releases fine water droplets and negative ions generated by crushing the hot water in the water storage section 6 heated to a temperature higher than the temperature. Supplied from the mouth 5 in the sauna room 2, by circulating sequentially air sauna chamber 2 by repeating this, in which immediately performs the launch of the sauna room 2.

  Next, the operation in the start-up mode will be described with reference to the flowchart of FIG. 11. First, the control means 61 sets the blower 35 to a strong operation and starts driving the blower 35 and energizes the air heater 43. (Step S301) When the hot water temperature in the water storage section 6 detected by the water storage temperature sensor 44 becomes 46 ° C. or less, the heater 9 is energized and the hot water temperature in the water storage section 6 detected by the water storage temperature sensor 44 is 48. When the temperature becomes equal to or higher than 0 ° C., the heater 9 is ON / OFF controlled so as to keep the hot water temperature of the water storage unit 6 at a predetermined temperature higher than the set temperature, such as turning off the power to the heater 9 (step S302). ), Step S302 is repeated until the detected temperature detected by the room temperature sensor 46 provided in the upper part of the sauna room 2 reaches the set temperature (step S303). . If it is determined that the set temperature has been reached (YES in step S303), the bath lamp 60 of the remote controller 52 is turned on, and a buzzer (not shown) is sounded. % Of the low-temperature sauna is used and a notification is made that it is possible to enter the room (step S304), and the start-up mode is terminated.

  Even when the hot water in the water storage section 6 decreases during this start-up mode, the control means 61 controls the automatic water supply valve 8 based on the detection signal from the water level detection means 39 (float switches 40 and 41). The water supply is controlled to keep the water storage unit 6 within a predetermined water level range.

  In the start-up mode described above, the blower 35 is set to a strong operation to start driving the blower 35, and the air heater 43 attached to the air supply port 36 is energized, and further stored in the water storage unit 6. The air in the sauna room 2 circulated by the blower 35 is sucked into the suction duct 4 by ON / OFF control of the heater 9 so as to keep the hot water temperature at a temperature higher than the set temperature set by the room temperature setting switch 55. The air in the sauna room 2 is sucked through the air and first heated and heated by the air heater 43, and then the heated and heated air is heated and heated to a temperature higher than the set temperature by a predetermined temperature. The fine water droplets and negative ions generated by crushing the hot water in the water storage unit 6 are put on the humidified air having a temperature higher than the set temperature from the discharge port 5 by the strong operation of the blower 35. Since the air in the sauna room 2 is vigorously supplied, the air in the sauna room 2 is sufficiently agitated so that the temperature in the sauna room 2 can be increased uniformly and rapidly. The air inside can be quickly circulated, and this can be repeated in sequence to quickly start up the sauna room 2 until a low temperature sauna atmosphere is formed at the set temperature and the room can be entered.

  Further, in this start-up mode, the rotating body 24 rotates, so that the rotating body 24 that is submerged in the water storage section 6 is lifted along the surface by centrifugal force from the lower surface of the rotating body 24 and the back surface of the rotating body 24 and rotated. Part of the hot water that is scattered from the plurality of pores 25 at the upper end of the body 24 toward the outer periphery and collided with the porous body 29 rotating simultaneously with the rotating body 24 is crushed into fine water droplets. A part of the other warm water passes through the porous portion 30, collides with the inner wall of the air guide tube 31 on the outer periphery of the porous body 29 and is further crushed into fine water droplets, and a mist containing nanometer-sized fine water droplets and large water droplets is formed. At the same time, due to the Leonard effect, the fine water droplets are negatively charged and the surrounding air is negatively charged to generate negative ions.

  In addition, air in the sauna chamber 2 flows from the air supply port 36 through the suction duct 4 by driving the blower 35, and is guided to the air guide cylinder 31 from above the rotating rotator 24 so that the inside of the processing chamber 15. At this time, a pair of large flow passages 32, 32 and a pair of small flow passages 33, 33 are formed between the cylindrical porous body 29 and the elliptical air guide tube 31. As the air flows there, a pressure difference is generated according to Bernoulli's theorem, and air flows from the high flow passages 32, 32 side having high pressure to the small flow passages 33, 33 side having low pressure. Large mist easily falls and only fine water droplets exist, and a large amount of negative ions can be obtained by contacting a large amount of air with water particles that are negatively charged fine water droplets. At this time, the dust contained in the air Bacteria are surrounded by large water droplets other than fine water droplets, fall into the warm water of the reservoir 6 and remain in the water as they are, so that air purification is also performed at the same time. This air purification also becomes turbulent air flow. It is done well.

  Further, the hot water in the water storage section 6 heated and heated is crushed in the processing chamber 15, and the generated air containing mist and negative ions is a downward flow passing through the communication path 17 below the partition wall 14. The large water droplets fall into the water by their own weight, and the fine water droplets left in the process of ascending the separation chamber 16 first hit the first baffle plate 26 at the lower end of the partition wall 14 and grow into large water droplets. Then, it falls while it circulates through the meandering path 28, hits the second baffle plate 27, grows and drops into the last large water droplet, circulates again through the meandering path 28, and finally Nanometer-sized fine water droplets are discharged from the discharge port 5 into the sauna room 2 through the blower 35, thereby reliably preventing the release of large water droplets and the nanometer-sized fine water droplets and negatively charged air. Negative ion only , Will be discharged from the discharge port 5, the floor and walls be covered concerned can be used safely without those capable water microdroplets and negative ions to form a full good sauna atmosphere.

  When the start-up mode in step S300 is completed, the operation proceeds to the stable mode (step S400). In this stable mode, the water storage section that detects the ON / OFF control of the heater 9 with the water storage temperature sensor 44. By switching from the control based on the hot water temperature of 6 to the control based on the room temperature in the sauna room 2 detected by the room temperature sensor 46, a stable and comfortable sauna bathing at the set temperature can be performed. By switching 35 from strong driving to weak driving, noise in the sauna room 2 is suppressed and the user can perform comfortable sauna bathing.

  Next, the operation in the above-described stable mode will be described with reference to the flowchart of FIG. 12. First, the control means 61 turns off the energization to the air heater 43 and makes the blower 35 operate weakly (step S401). Counting of a predetermined time (for example, 60 minutes) that is a preset operation time is started (step S402). Here, the continuous operation time starts counting when the inside of the sauna room 2 reaches a set temperature. Subsequently, when the control temperature, which is the temperature detected by the room temperature sensor 46, is lower than the set temperature, the heater 9 is energized, and when the temperature in the sauna room 2 detected by the room temperature sensor 46 is higher than the set temperature, The heater 9 is ON / OFF controlled so as to keep the temperature in the sauna room 2 at the set temperature so as to turn off the power to the heater 9 (step S403), and for a predetermined time from the start of continuous operation, For example, when 10 minutes have elapsed, the ventilation fan 47 is driven for a predetermined time, for example, about 10 seconds to ventilate the sauna room 2, and when 10 seconds have elapsed, the ventilation fan 47 is turned off, and when 10 minutes have elapsed again, the ventilation fan 47 has approximately 10 seconds. The ventilation fan 47 is controlled so that the ventilation in the sauna room 2 is performed and the ventilation fan 47 is turned off after 10 seconds (step S404). Count until completion of repeating the steps S403 and the step S404 (step S405).

  When it is determined that the continuous operation time has been counted (YES in step S405), a buzzer is sounded, the bath lamp 60 and the operation lamp 57 are turned off, and the blower 35 is stopped (step S406). To finish sauna operation. If the operation switch 56 is turned OFF during the stable mode, the process immediately proceeds to the process of step S406, the stable mode is ended, and the sauna operation is ended.

  Even when the hot water in the water storage section 6 decreases during this stable mode, the control means 61 controls the automatic water supply valve 8 based on the detection signal from the water level detection means 39 (float switches 40 and 41). Thus, water is supplied to keep the water reservoir 6 within a predetermined water level range.

  In the stable mode described above, the ON / OFF control of the heater 9 is controlled from the control based on the hot water temperature of the water storage section 6 detected by the water storage temperature sensor 44 as in step S302 of the start-up mode. In this way, by switching the control so that the room temperature in the sauna room 2 detected by the room temperature sensor 46 is kept at the set temperature, the hot water in the water storage section 6 by the heater 9 is set so that the inside of the sauna room 2 becomes the set temperature. Since the heating amount is adjusted and the heated / humidified air is supplied into the sauna room 2, the temperature becomes stable with little deviation from the set temperature, and a comfortable sauna bath can be performed.

  Further, by switching the blower 35 from the strong operation to the weak operation in step S401, when the user enters the sauna room 2, the noise in the sauna room 2 can be suppressed, and further, the fan 35 is operated weakly. By reducing the circulation of air in the sauna room 2, fluctuations in the room temperature in the sauna room 2 can be suppressed, and furthermore, the energization of the air heater 43 is stopped to prevent overheating in the sauna room 2. Therefore, the temperature in the sauna room 2 becomes stable with little deviation from the set temperature, and a comfortable sauna bath can be performed.

  Further, by performing the control for driving the ventilation fan 47 for a predetermined time every predetermined time as in step S404, fresh air is occasionally generated from the outside of the sauna room 2 through the air intake 50 into the sealed sauna room 2. It is supplied and can relax the breathlessness peculiar to a sauna, and can perform comfortable sauna bathing.

  In addition, when bathing in a sauna in a low-temperature sauna atmosphere 2 with a set temperature of 38 ° C to 42 ° C, nanometer-sized fine water droplets and a relative humidity of 90% or more and full of negative ions, water molecules added negative ion molecules are directly By opening the sweat glands by acting on the skin, etc., sweating can be facilitated, and a large amount of sweat can be discharged to discharge waste products in the body, and negative ions sucked from the lungs enter the blood and reduce it It is thought that pain and punishment can be alleviated by preventing blood oxidation and making the blood smooth, improving circulation and spreading blood to peripheral blood vessels.

  In addition, the negative ions have fatigue recovery effect, mental stability effect, blood purification effect, resistance enhancement effect, autonomic nerve adjustment effect, etc., and nanometer-sized fine water droplets to every corner in the air Suppresses dirty air and bacteria and breaks down odors, and still has a deodorizing effect, dust removing effect, sterilizing effect, and of course a humidifying effect. This humidification is smooth and moist air with no stickiness. It has the effect of keeping the skin and hair moistened by penetration from the pores.

  When the stable mode is finished in step S400 and the sauna operation is finished, the operation is subsequently shifted to the sterilization mode B (step S500), which is the termination operation of the sauna device. In this sterilization mode B, the blower is used in the sauna operation. As a result of driving 35 to circulate the air in the sauna chamber 2, the hot water in the water storage unit 6 that has taken in bacteria and the like is heated to a temperature that can be sterilized by the heater 9, and the rotating body 24 is rotated. By driving the motor 22, the hot water stored in the water storage unit 6 is sterilized, and the hot water heated from the water storage unit 6 is pumped by the hot water, and the rotary body arranged on the outer periphery of the rotary body 24. Dust, dust, bacteria, etc. adhering to the porous body 29 rotating together with the air guide 24 and the air guide cylinder 31 arranged so as to cover the porous body 29 are washed away to make it clean. Body 24, porous body 29, in which the air guide cylinder 31 is sterilized and sterilization.

  Next, the operation of the sterilization mode B will be described with reference to the flowchart of FIG. 13. First, the control means 61 first determines a predetermined temperature at which the hot water temperature in the water storage section 6 detected by the water storage temperature sensor 44 can be sterilized, for example 60 It is determined whether or not the temperature is higher than or equal to ° C. (step S501), and when it is determined that the temperature of the hot water in the water storage unit 6 is 60 ° C. or higher, the power to the heater 9 is turned off and the water in the water storage unit 6 (warm water). Is counted for a predetermined time for heat sterilization, that is, sterilization time (step S502), and when the hot water temperature in the water storage section 6 detected by the water storage temperature sensor 44 becomes 58 ° C. or lower, the heater 9 is energized, When the hot water temperature in the water storage unit 6 detected by the water storage temperature sensor 44 becomes 60 ° C. or higher, the hot water temperature in the water storage unit 6 is kept at a sterilizable temperature so that the power supply to the heater 9 is turned off. And ON / OFF control of the heater 9 so (step S503), sterilization time, repeating said steps S503 example until the count of one minute is finished (step S504). If it is determined that the sterilization time has been counted (YES in step S504), the heater 9 is turned off, the rotation motor 22 is stopped, and the automatic drain valve 13 is opened. In step S505, the sterilization mode B is terminated.

  In the sterilization mode B described above, as a result of circulating the air in the sauna room 2 by the sauna operation, the warm water in the water storage unit 6 that has taken in bacteria and the like is heated to a sterilizable temperature and the temperature is maintained for a predetermined time. By keeping the rotation and driving the rotating motor 22 for rotating the rotating body 24, the water stored in the water reservoir 6 is agitated by the rotation of the rotating body 24, and the hot water temperature in the water reservoir 6 is heated uniformly. Therefore, the water in the water storage unit 6 can be heat sterilized evenly, the inner wall of the water storage unit 6 in contact with the hot water of the water storage unit 6 can also be heat sterilized, and further, by rotating the rotating body 24, The hot water in the water storage unit 6 heated to a sterilizable temperature rises along the surface from the lower end of the rotating body 24 submerged by the centrifugal force from the front and back surfaces of the rotating body 24, 25 pores Part of the hot water scattered and pumped to the outer periphery collides with the porous body 29 rotating at the same time as the rotating body 24, and another part of the hot water passes through the porous portion 30 and the outer periphery of the porous body 29. Since it collides with the inner wall of the air guide cylinder 31, the rotating body 24, the porous body 29, dust, dust, bacteria, etc. adhering to the air guide cylinder 31 can be washed away to make it clean. The body 29 and the air guide tube 31 can be sterilized and sterilized, and the hot water in the water storage unit 6 that has been heat sterilized can be drained to keep the water storage unit 6 clean.

  When the sterilization mode B in step S500 is completed, the process proceeds to the drying mode (step S600). In this drying mode, the air blower 35 is started and the air attached to the air supply port 36 is started. By energizing the heater 43 and further driving the ventilation fan 47, the inside of the fine water droplet and negative ion generator 1, the suction duct 4, and the sauna chamber 2 are dried.

  Next, the operation of the above-described drying mode will be described with reference to the flowchart of FIG. 14. First, the control unit 61 sets the blower 35 to a strong operation and starts driving the blower 35, and energizes the air heater 43. Further, the ventilation fan 47 is driven (step S601), the ventilation lamp 59 is turned on, and it is determined whether or not a preset drying time, for example, 90 minutes has been counted (step S602), and it is determined that the drying time has ended. Then, the drive of the blower 35 is stopped, the energization of the air heater 43 is turned off, the drive of the ventilation fan 47 is stopped (step S603), the ventilation lamp 59 is turned off, the drying mode is finished, and the sauna apparatus is finished. When the operation is finished, the sauna apparatus is stopped. Note that the sauna device is in a stopped state while the automatic drain valve 13 is in the open state.

  In the drying mode described above, the air blower 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 driven to discharge moisture in the sauna room 2. The air heated by the air heater 43 is circulated in the fine water droplets and negative ion generator 1, the suction duct 4 and the sauna chamber 2, so that the fine water droplets and negative ions generator 1, the suction duct 4 and the sauna are circulated. Since the inside of the chamber 2 is dried, the generation of mold and the propagation of bacteria and the like in the apparatus 1, the suction duct 4 and the sauna chamber 2 can be prevented.

  Further, since only the automatic drain valve 13 is opened when the sauna device is stopped, water is not stored in the water storage unit 6 when the sauna device is stopped, and fine water droplet and negative ion generators are used. The inside of 1 can be kept clean.

  In addition, as described above, in the series of operations from the start of operation of the sauna device to the stop of operation, the two-time sterilization mode (sterilization mode A and By performing the sterilization mode B), it is possible to surely sterilize the fine water droplets and the negative ion generator 1, particularly the water storage unit 6, the rotating body 24, the porous body 29, and the air guide tube 31. After B, by performing the drying mode, the sauna apparatus after draining the hot water in the water storage unit 6, especially the fine water droplets and negative ion generator 1, the sauna room 2, and the suction duct 4 are dried, The sauna device can be kept clean and can reliably prevent the growth of bacteria, germs, etc., thereby realizing a sauna device with excellent hygiene.

  Further, the sterilization time in the sterilization mode A and the sterilization time in the sterilization mode B are set to a predetermined time, 1 minute in this embodiment, and the same time is used in the sterilization mode A and the sterilization mode B. However, the sterilization time in the sterilization mode B may be longer than the sterilization time in the sterilization mode A. This is because the sauna operation in which fine water droplets and negative ions are supplied into the sauna room 2 and the air in the sauna room 2 is circulated, bacteria and the like contained in the air circulating in the sauna room 2 are treated. Since it may be trapped by water droplets in the chamber 15 and kept in the warm water of the water storage section 6, or may adhere to parts such as the rotating body 24 and the porous body 29 in the processing chamber 15, bacteria may propagate. Then, by sterilizing time in the sterilization mode B after the sauna operation is made longer than the sterilization time in the sterilization mode A before starting the sauna operation, these bacteria and the like are sterilized more reliably. Is something that can be done.

  Further, when the water storage unit 6 is emptied due to a failure of the float switch 40 and the heater 9 is energized, the heating heat of the heater 9 is separated before being released from the discharge port 5 by the blower of the blower 35. Since the temperature increases due to accumulation in the second baffle plate 27 that spreads downward and inclines in the chamber 16, an overheating prevention sensor 45 is provided on the outer wall of this portion, so that an instantaneous overheating can be made without mistakes. Thus, the entire drive including the energization stop of the heater 9 is stopped via the control means 61, and safety can be measured, so that it can be used safely and safely.
