  Next, the operation of the sterilization mode A will be described with reference to the flowchart of FIG. 9. First, the control means 62 determines whether or not the low water level detection float switch 41 is ON (step S201). If it is determined that the switch 41 is ON, the heater 9 that heats the water in the water storage section 6 is energized, and the drive of the rotating motor 23 that rotates the rotating body 25 is started (step S202). It is determined whether or not the temperature of the hot water in the water storage unit 6 detected at 45 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 45 becomes 58 ° C. or less, the heater 9 is energized again, and the water storage temperature sensor 45 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 42 is turned on after the float switch 41 is turned on in step S201, the control means 62 closes the automatic water supply valve 8 and terminates the water supply. Yes, the control means 62 controls the automatic water supply valve 8 to supply water based on the detection signal from the water level detection means 40 (float switches 41 and 42), and keeps 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 23 that rotates the rotating body 25 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 25, the porous body 30, and the air guide cylinder 32, the rotation is continued. The hot water stored in the water storage unit 6 is agitated by the rotation of the body 25 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 sterilized evenly, 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 the rotating water 25 is rotated so that the hot water in the water storage unit 6 heated to a sterilizable temperature is submerged. The bottom of the rotating body 25 A part of hot water pumped up from the front and back surfaces of the rotator 25 along the surface by centrifugal force is scattered from the plurality of pores 26 at the upper end of the rotator 25 toward the outer periphery. Since it collides with the rotating porous body 30 and part of other hot water passes through the porous portion 31 and hits the inner wall of the air guide tube 32 on the outer periphery of the porous body 30, the rotating body 25, the porous body 30, and the air guide Dust, dust, bacteria, etc. adhering to the cylinder 32 can be washed away to a clean state, and the rotating body 25, the porous body 30, and the air guide cylinder 32 can be sterilized and sterilized. The inner wall of the water storage unit 6, the rotating body 25, the porous body 30, the air guide tube 32, and the clean hot water in the water storage unit 6 that have been sterilized by heating can be used for sauna operation. 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. 36 is set to a strong operation to start the driving of the blower 36, the air heater 44 attached to the air supply port 37 is energized, and the hot water temperature stored in the water storage section 6 is set to the room temperature setting switch 56. 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 44 and set by the fine water droplet and negative ion generator 1. The blower 36 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. 10. First, the control means 62 sets the blower 36 to a strong operation and starts driving the blower 36 and energizes the air heater 44. (Step S301) When the hot water temperature in the water storage section 6 detected by the water storage temperature sensor 45 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 45 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 47 provided in the upper part of the sauna room 2 reaches the set temperature (step S303). . When it is determined that the set temperature has been reached (YES in step S303), the bath lamp 61 of the remote controller 53 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 62 controls the automatic water supply valve 8 based on the detection signal from the water level detection means 40 (float switches 41, 42). 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 36 is set to a strong operation to start driving the blower 36, the air heater 44 attached to the air supply port 37 is energized, and the water is stored in the water storage unit 6. The heater 9 is ON / OFF controlled so as to keep the hot water temperature at a temperature higher than the set temperature set by the room temperature setting switch 56, so that the air in the sauna room 2 circulated by the blower 36 is sucked into the suction duct 4. The air in the sauna room 2 is sucked through the air, first heated and raised by the air heater 44, and then heated and heated to a temperature higher by a predetermined temperature than the set 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 36. 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 25 rotates, so that the rotating body 25 that is submerged in the water storage section 6 is raised from the lower end of the rotating body 25 along the surface by centrifugal force from the surface and the back surface of the rotating body 25 and rotated. A portion of the hot water scattered from the plurality of pores 26 at the upper end of the body 25 and pumped up collides with the porous body 30 rotating simultaneously with the rotating body 25 to be crushed into fine water droplets. A part of the other warm water passes through the porous portion 31, collides with the inner wall of the air guide tube 32 on the outer periphery of the porous body 30 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 37 through the suction duct 4 by driving the blower 36, and is guided to the air guide cylinder 32 from above the rotating rotator 25 so that the inside of the processing chamber 16. At this time, a pair of large flow passages 33, 33 and a pair of small flow passages 34, 34 are formed between the cylindrical porous body 30 and the elliptical air guide tube 32. As the air flows there, a pressure difference is generated according to Bernoulli's theorem, and air flows from the large flow passages 33, 33 having a high pressure to the small flow passages 34, 34 having a 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 16, and the generated air containing mist and negative ions is a downward flow passing through the communication path 18 below the partition wall 15. The large water droplets fall into the water by their own weight, and the fine water droplets remaining in the process of ascending the separation chamber 17 first collide with the first baffle plate 27 at the lower end of the partition wall 15 and grow into large water droplets. Then, it falls while flowing through the meandering path 29, hits the second baffle plate 28, grows and drops into the last large water droplet, and then flows again through the meandering path 29, finally Nanometer-sized fine water droplets are discharged from the discharge port 5 into the sauna chamber 2 through the blower 36, thereby reliably preventing the release of large water droplets by 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 45. 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 47, a stable and comfortable sauna bathing at the set temperature can be performed. By switching 36 from strong driving to weak driving, noise in the sauna room 2 can be 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. 11. First, the control means 62 turns off the energization to the air heater 44 and makes the blower 36 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 temperature in the sauna room 2 detected by the room temperature sensor 47 becomes a set temperature of −0.5 ° C. or lower, the heater 9 is energized and the temperature in the sauna room 2 detected by the room temperature sensor 47 is set. When the temperature exceeds the temperature, the heater 9 is turned on / off to keep the temperature in the sauna room 2 at the set temperature, such as turning off the power to the heater 9 (step S403), and the hot water at that time The temperature is about 40 ° C to 50 ° C. Then, when a predetermined time, for example, 10 minutes elapses from the start of continuous operation, the ventilation fan 48 is energized for a certain period of time, for example, about 10 seconds, and the ventilation fan 48 is driven to ventilate the sauna room 2. 48, the ventilation fan 48 is controlled so that the ventilation fan 48 is energized and driven for about 10 seconds to drive the ventilation in the sauna room 2 after 10 minutes have passed, and the ventilation fan 48 is turned off after 10 seconds. Step S404) Until the continuous operation time is counted, step S403 and step S404 are repeated (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 61 and the operation lamp 58 are turned off, and the blower 36 is stopped (step S406). When the operation switch 57 is turned OFF, the stable mode is terminated and the sauna operation is terminated. If the operation switch 57 is turned OFF by the user during the continuous operation time in the stable mode, the process immediately proceeds to the process of step S406, ends the stable mode, and ends the sauna operation.

  Even when the hot water in the water storage section 6 decreases during this stable mode, the control means 62 controls the automatic water supply valve 8 based on the detection signal from the water level detection means 40 (float switches 41, 42). 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 45 as in the step S302 of the start-up mode. In this way, by switching the control to keep the room temperature in the sauna room 2 detected by the room temperature sensor 47 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 36 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 furthermore, the blower 36 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 the energization of the air heater 44 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.

  In addition, by performing the control for driving the ventilation fan 48 for a predetermined time every predetermined time as in step S404, fresh air is occasionally discharged from the outside of the sauna room 2 through the air intake 51 into the sealed sauna room 2. In addition to being able to take in, the breathing in the sauna room 2 in a high humidity atmosphere can be alleviated, and the sauna room 2 is kept in a low temperature and high humidity sauna atmosphere that encourages sweating, especially with a humidity of 90% or more It is possible to hold a comfortable sauna bath sufficiently.

  In addition, when bathing in a sauna in a low-temperature sauna atmosphere 2 with a set temperature of 38 ° C. to 42 ° C. and fine water droplets of nanometer size and a relative humidity of 90% or more and full of negative ions, water molecules added negative ion molecules group 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 36 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 25 is rotated. By driving the motor 23, 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 25. Dust, dust, bacteria, etc. adhering to the porous body 30 rotating together with the air guide 25 and the air guide cylinder 32 arranged so as to cover the porous body 30 are washed away to make it clean. Body 25, porous body 30, in which the air guide cylinder 32 is sterilized and sterilization.

  Next, the operation of the sterilization mode B will be described with reference to the flowchart of FIG. 12. First, the control means 62 first determines a predetermined temperature at which the hot water temperature in the water storage section 6 detected by the water storage temperature sensor 45 can be sterilized, for example 60 It is determined whether or not the temperature is higher than or equal to ° C. (step S501). 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 45 becomes 58 ° C. or less, the heater 9 is energized, When the hot water temperature in the water storage unit 6 detected by the water storage temperature sensor 45 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 23 is stopped, and the automatic drain valve 13 is opened. Then, drainage is started (step S505), it is determined whether or not the low water level detection float switch 41 is OFF (step S506), and while it is determined that the float switch 41 is not OFF, the process of step S506 is performed. When it is determined that the float switch 41 is turned off repeatedly, the automatic water supply valve 8 is opened after waiting for a predetermined time until the hot water in the water storage unit 6 becomes empty, and after the drainage of the hot water in the water storage unit 6 is completed (step). S507). In step S507, the automatic water supply valve 8 is opened to start water supply into the water storage unit 6, and then set for a certain period of time, for example, based on a test result performed in advance, and drained from the water storage unit 6 into the drain trap 14 It is determined whether or not the time required to replace the stored warm water at the sterilizable temperature with water supply has elapsed (step S508), and when it is determined that this predetermined time has elapsed, the automatic water supply valve 8 is closed ( Step S509) and the sterilization mode B are ended. Here, as in step S506, the automatic water supply valve 8 is opened after the judgment of the float switch 41 for detecting the low water level and a delay of a predetermined time. The automatic water supply valve 8 may be opened when the drainage time has elapsed.

  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 23 for rotating the rotating body 25, the water stored in the water storage section 6 is agitated by the rotation of the rotating body 25, and the hot water temperature in the water storage section 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 that is in contact with the hot water of the water storage unit 6 can also be heat sterilized, and further, the rotating body 25 rotates, 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 25 that is submerged by centrifugal force from the front and back surfaces of the rotating body 25, Pores 26 Part of the hot water scattered and pumped to the outer periphery collides with the porous body 30 rotating at the same time as the rotating body 25, and part of the other hot water passes through the porous portion 31 and the outer periphery of the porous body 30. Since it collides with the inner wall of the air guide tube 32, the rotating body 25, the porous body 30, dust, dust, bacteria, etc. adhering to the air guide tube 32 can be washed away, and the rotating body 25, porous The body 30 and the air guide tube 32 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.

  In addition, the counting of the sterilization time is completed, the automatic drain valve 13 is opened in the step S505, the automatic water supply valve 8 is opened in the step S507, and in the drain trap 14 in the step S508 for a certain time, here. By supplying water for a period of time so that the hot water stored at the sterilizable temperature is replaced with the feed water, the water in the drain trap 14 is replaced with the hot water at the sterilizable temperature by the supplied water, and chlorine having a sterilizing action without wasteful water supply. Since water (tap water) containing a large amount can be stored in the drain trap 14, it is possible to prevent breeding of bacteria and the like in the drain trap 14. It is possible to prevent the occurrence of occurrence or bad odor and standing in the sauna room 2 in advance.

  When the sterilization mode B in step S500 is completed, the operation proceeds to the drying mode (step S600). In this drying mode, the air blower 36 is started and air attached to the air supply port 37 is started. By energizing the heater 44 and further driving the ventilation fan 48, the inside of the fine water droplet and negative ion generator 1, the suction duct 4, and the sauna room 2 are dried.

  Next, the operation of the above-described drying mode will be described with reference to the flowchart of FIG. 13. First, the control means 62 sets the blower 36 to a strong operation and starts driving the blower 36, and energizes the air heater 44. Further, the ventilation fan 48 is driven (step S601), the ventilation lamp 60 is turned on, and it is determined whether or not a preset time, for example, 30 minutes has elapsed since the start of the drying mode (step S602). If it is determined that the time has elapsed, the rotation motor 23 is driven (step S603), the rotation body 25 and the porous body 30 are rotated, and it is determined whether or not, for example, 10 seconds have elapsed. When it is determined that 10 seconds have elapsed (step S604), the driving of the rotating motor 23 is stopped (step S605). The rotation of the porous body 30 is stopped, and then it is determined whether or not the preset drying time, for example, the 90-minute count from the start of the drying mode is ended (step S606), and the drying time is determined to be ended. Then, the driving of the blower 36 is stopped, the energization of the air heater 44 is turned off, the driving of the ventilation fan 48 is stopped (step S607), the ventilation lamp 60 is turned off, the drying mode is ended, and the sauna apparatus is ended. When the operation is finished, the sauna apparatus is stopped. If the ventilation switch 59 is turned OFF by the user during the drying time in the drying mode, the process immediately proceeds to the process of step S607, the drying mode is ended, the sauna apparatus finishes the operation, and the sauna apparatus stops. It becomes a state. In addition, the sauna device is in a stopped state while the automatic drain valve 13 is open.

  The set time in step S602 is based on the results of tests performed in advance, and all the water remaining in the water reservoir 6 after the automatic water supply valve 8 is closed in step S509 in the sterilization mode B is all. The time when the water is drained and the drying of the fine water droplets and negative ion generator 1 proceeds to some extent is set, and after the rotation of the motor 23 for rotation is stopped in step S605, the fine water droplets and negative ion generator 1 The time is set so as to leave a drying time for sufficient drying.

  In the drying mode described above, the air blower 36 is started to be driven, the air heater 44 attached to the air supply port 37 is energized, and the ventilation fan 48 is driven to discharge moisture in the sauna room 2. The air heated by the air heater 44 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 and 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, the surface exposed to the air supply chamber 38 of the waterproof cover 21 that accommodates the rotation motor 23 by waiting for a preset time, in this case 30 minutes, to elapse from the start of the drying mode in step S602. A certain amount of water droplets adhering to the water drops directly on the upper surface of the rotator 25 or accumulates on the upper surface of the rotator 25 through the support shaft 24. Further, the sauna device dries to some extent, so that a new waterproof cover 21 The opportunity for water to drop and adhere to the upper surface of the rotating body 25 is reduced. At that time, the rotating motor 23 is driven in step S603 to rotate the rotating body 25 and the porous body 30 and adhere to the water accumulated on the upper surface of the rotating body 25 and the porous portion 31 of the porous body 30. Since the water that is being discharged is scattered, the drying of the rotating body 25 and the porous body 30 can be promoted, the drying can be reliably performed within the drying time of the drying mode, and the sauna apparatus can be kept clean. It is something that can be done.

  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 25, the porous body 30, and the air guide tube 32. 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, in the sauna operation consisting of the start-up mode and the stable mode, the ventilation fan 48 is not energized during the start-up mode, so until the inside of the sauna room 2 reaches the set temperature after the start of the sauna operation, There is no decrease in temperature and humidity in the sauna room 2 due to ventilation, the rise time of the sauna room 2 can be shortened, and further, the room temperature in the sauna room 2 is set to the set temperature after the stable mode is started. After reaching the value, the ventilation fan 48 is energized for a certain short period of time every predetermined time to drive the ventilation fan 48 to ventilate the sauna room 2. In addition to being able to be taken into the sauna room 2, the sauna room 2 can be kept in a low-temperature and high-humidity sauna atmosphere, in particular at a humidity of 90% or more, and a comfortable sauna bathing can be performed sufficiently. It is.

  Next, when the user manually operates the operation switch 57 during each mode described above to instruct to stop the operation of the sauna apparatus, that is, when the operation switch 57 is turned OFF, the operation shown in FIG. 14 is used. I will explain. As described above, normally, the sauna operation is ended, the operation lamp 58 is turned off, and the operation switch 57 is automatically turned off at the end of the stable mode. Transition to sterilization mode B. However, even when the user manually turns off the operation switch 57 during the cleaning mode, the sterilization mode A, and the start-up mode, if the mode is uniformly shifted to the sterilization mode B, the heater 9 or the like is driven. Since power is unnecessarily consumed by energizing parts, it is intended to eliminate waste such as power consumption by making a transition to an appropriate process corresponding to each mode.

  Here, when the operation switch 57 is turned OFF by the user during the cleaning mode, the operation lamp 58 is turned off, and the automatic drain valve is followed according to the arrow shown by the one-dot chain line drawn from the cleaning mode in FIG. Transition to a stop state in which 13 is opened. This is because the cleaning mode is just after the start of use of the sauna device, so there is no problem even if it is immediately shifted to the stop state without performing the sterilization mode B or the drying mode. Thus, it is possible to shift to an appropriate process without performing unnecessary operations and eliminate waste of power consumption.

  Further, when the operation switch 57 is turned OFF by the user during the sterilization mode A, the operation lamp 58 is turned off, and the arrow shown by the one-dot chain line drawn from the sterilization mode A in FIG. A transition is made to a stopped state in which the automatic drain valve 13 is opened. This is a state in which the sterilization mode A is sterilizing and sterilizing the supplied water, the water storage unit 6, the rotating body 25, and the like, and supplying fine water droplets and negative ions into the sauna room 2. Because there is no need to dry the inside of the sauna room 2, there is no problem even if the sterilization mode B or the drying mode is performed immediately without going into the sterilization mode, and by doing so, the cleanliness of the sauna apparatus While maintaining the above, it is possible to shift to an appropriate process without performing unnecessary operations, thereby eliminating waste of power consumption.

  When the operation switch 57 is turned off by the user during the start-up mode, the operation lamp 58 is turned off, the sauna operation is stopped, and the one-dot chain line drawn from the start-up mode in FIG. Transition to the drying mode according to the arrow indicated by. This is a mode in which the start-up mode transitions after the sterilization mode A, and sterilization is performed in the sterilization mode A, so there is no need for further sterilization, and fine water droplets in the sauna room 2 Since it is in a state where negative ions are being supplied, it is necessary to dry the inside of the sauna room 2, so that the mode is changed to a drying mode, so that unnecessary operations can be performed while keeping the sauna apparatus clean. Therefore, it is possible to shift to an appropriate process and eliminate waste of power consumption.

  If the operation switch 57 is turned off before the end of the continuous operation time in the stable mode, the operation lamp 58 is turned off, the sauna operation is stopped, and one point drawn from the stable mode in FIG. Transition to sterilization mode B follows the arrow indicated by the chain line. This is because the hot water in the water storage section 6 is used for sauna operation and needs to be sterilized and sterilized when it reaches the stable mode from the start of the sauna operation, and fine water droplets in the sauna room 2 Since the inside of the sauna room 2 needs to be dried because it is in the state of supplying negative ions, the transition is made to the sterilization mode B, and the end operation consisting of the sterilization mode B and the drying mode is performed. By doing so, it is possible to shift to an appropriate process without performing unnecessary operations while maintaining the cleanliness of the sauna apparatus.

  If the operation switch 57 is turned off before the end of the continuous operation time in the stable mode, the operation lamp 58 is turned off, the sauna operation is stopped, and one point drawn from the stable mode in FIG. According to the arrow indicated by the chain line, transition to the sterilization mode B is performed, but as a special operation, within the preset time after the operation switch 57 is turned OFF before the end of the continuous operation time in the stable mode. For example, when the operation switch 57 is operated within 20 seconds to start the operation of the sauna device, that is, when the operation switch 57 is turned ON again, as shown by the two-dot chain line in FIG. can do. By doing so, even if the user turns off the operation switch 57 due to an erroneous operation or the like, if the operation switch 57 is turned on within a predetermined time, the operation is resumed from the stable mode, thereby improving user convenience. In addition, it is possible to continuously perform a comfortable sauna bathing without waiting until the sauna room 2 becomes ready for the sauna bathing again.

Next, an abnormal stop mode executed when an abnormality occurs, for example, when the emergency switch 52 provided in the sauna room 2 is operated during the stable mode in which the user (bathing person) is taking a bath in the sauna (Step S700) will be described with reference to the flowchart of FIG.
First, the control means 62 determines whether or not the emergency switch 52 has been operated (step S701). If it is determined that the emergency switch 52 has been operated, it is directed to the outside of the sauna room 2 to call a family or the like. Abnormality is notified by sounding a buzzer or the like (step S702), the automatic drain valve 13 is opened and the ventilation fan 48 is driven, and the heater 9, fan 36, and rotation motor 23 other than the automatic drain valve 13 and the ventilation fan 48 are driven. Is stopped (step S703), and the abnormal stop mode is terminated.

  If it is determined in step S701 that the emergency switch 52 has not been operated, whether or not the temperature in the sauna room 2 detected by the room temperature sensor 47 is a predetermined temperature higher than the set temperature, for example, 50 ° C. or higher. If it is determined (step S704) and it is determined that the temperature in the sauna room 2 is 50 ° C. or higher, the process proceeds to step S703, the automatic drain valve 13 is opened, the ventilation fan 48 is driven, and the automatic The heater 9 other than the drain valve 13 and the ventilation fan 48, the blower 36, and the rotation motor 23 are stopped, and an error code indicating that the room temperature in the sauna room 2 is abnormal is displayed in the indoor set temperature display section 54 of the remote controller 53 or An error code is displayed on the room temperature display section 55 and the abnormal stop mode is terminated.

  If it is determined in step S704 that the temperature in the sauna room 2 detected by the room temperature sensor 47 is not 50 ° C. or higher, the hot water temperature in the water storage unit 6 detected by the water storage temperature sensor 45 is normal during the stable mode. When it is determined whether or not the temperature of the hot water to be used is a predetermined temperature higher than about 40 ° C. to 50 ° C., for example, 60 ° C. or more (step S705), Goes to step S703, opens the automatic drain valve 13 and drives the ventilation fan 48, and stops the operation of the heater 9, fan 36, and rotation motor 23 other than the automatic drain valve 13 and the ventilation fan 48. An error code indicating that the hot water temperature in the water storage unit 6 is abnormal is displayed on the indoor set temperature display unit 54 or the indoor temperature display unit 55 of the remote controller 53. It is intended to end the emergency stop mode.

  When the error is canceled after the abnormal stop mode ends, the error is canceled by a special operation on the remote controller 53, for example, simultaneous pressing of the operation switch 57 and the ventilation switch 59. This is a stop state in which 13 is opened.

  When the emergency switch 52 is operated in the abnormal stop mode described above, bathing is performed in the sauna room 2 by sounding a buzzer outside the sauna room 2 to call a family or the like in step S702. In addition, in step S703, the automatic drain valve 13 is opened and the ventilation fan 48 is driven, so that the automatic drain valve 13 and the ventilation fan 48 are driven. By stopping the operation of the heater 9, the blower 36, and the rotation motor 23 other than the above, the supply of warming / humidified air into the sauna room 2 is stopped, and the automatic drain valve 13 into the sauna room 2 is further stopped. Since the hot water in the water reservoir 6 serving as a heat source is drained by opening the valve, it is possible to eliminate the hindrance to the temperature drop in the sauna room 2 due to the residual heat of the hot water in the water reservoir 6, and in addition, ventilation 48 is driven, the temperature and humidity in the sauna room 2 can be quickly reduced to return the sauna room 2 to a normal state, and the physical burden on the bather can be removed to ensure the safety of the bather. It can be done.

  If the temperature in the sauna room 2 detected by the room temperature sensor 47 reaches a predetermined temperature higher than the set temperature, the automatic drain valve 13 is opened and the ventilating fan 48 is driven in step S703, and the automatic drain valve 13 and the fan 36 and the rotation motor 23 other than the ventilation fan 48 are stopped to stop the supply of the heated / humidified air into the sauna room 2 and the automatic drain valve 13 is opened. Since the hot water in the water storage unit 6 that is a heat source is drained, the residual heat of the hot water in the water storage unit 6 is not hindered from lowering the temperature in the sauna room 2, and in addition, Since the ventilation fan 48 is driven, the temperature and humidity in the sauna room 2 can be quickly lowered to return the sauna room 2 to a normal state, and the safety of the bather can be ensured.

  If the hot water temperature in the water storage unit 6 detected by the water storage temperature sensor 45 reaches a predetermined temperature higher than the hot water temperature normally used during the stable mode, the automatic drain valve 13 is opened in the step S703. At the same time, the ventilation fan 48 is driven, and the heating heater 9, the blower 36 and the rotation motor 23 other than the automatic drain valve 13 and the ventilation fan 48 are stopped to stop the supply of warming / humidified air into the sauna room 2. Furthermore, since the automatic drain valve 13 is opened to discharge the hot water in the water storage unit 6 that is a heat source, the remaining heat of the hot water in the water storage unit 6 prevents the temperature drop in the sauna room 2 from being hindered. In addition, since the ventilation fan 48 is driven, the temperature and humidity in the sauna room 2 can be quickly lowered to return the sauna room 2 to a normal state, thereby ensuring the safety of the bather. Plan It is those that can.

Next, an operation when the user manually operates the ventilation switch 59 during each mode described above will be described.
First, a case where the ventilation switch 59 is turned off by the user during the sterilization mode B will be described. Normally, when the stable mode ends, the sterilization mode B, the drying mode, and the stop state are automatically changed in this order. However, when the stable mode ends and the sterilization mode B is started, the ventilation lamp 60 is turned on, the ventilation switch 59 is automatically turned on, and the sterilization mode B is processed. When the ventilation switch 59 is turned OFF by the user during the sterilization mode B, after the sterilization mode B is completed, the drying mode is canceled and the automatic drain valve 13 is opened to make a transition to a stopped state. In this way, when the user finishes bathing the sauna and determines that the sauna room 2 does not need to be ventilated or dried, the ventilation switch 59 can be turned off during the sterilization mode B after the sauna operation. For example, after the sterilization mode B is completed, the drying mode is canceled and the drying mode is not performed and the process is stopped. Therefore, the processing intended by the user can be performed, and the usability can be improved.

  When the ventilation switch 59 is turned on again during the sterilization mode B after the ventilation switch 59 is turned off by the user during the sterilization mode B, the drying mode is canceled after the sterilization mode B is finished. After the sterilization mode B is completed, the drying mode is performed, and the drying mode is stopped after the drying mode is completed. By doing so, even if the ventilation switch 59 is operated due to an erroneous operation by the user, and the sauna apparatus is likely to be stopped without performing the drying mode, the ventilation switch 59 is operated again during the sterilization mode B. Then, since the drying mode is performed, the sauna device, that is, the fine water droplet and negative ion generator 1 and the sauna chamber 2 can be dried.

  When the ventilation switch 59 is turned on by the user during the stop state, the ventilation lamp 60 is turned on to start driving the ventilation fan 48, the blower 36, and the air heater 44, for example, a preset set time, for example, When the count for 60 minutes is completed, the drive of the ventilation fan 48, the blower 36, and the air heater 44 is stopped, the ventilation lamp 60 is turned off, and the sauna apparatus is stopped. In this way, when the user determines that the inside of the sauna room 2 is not sufficiently dried, when the ventilation switch 59 is turned on, the ventilation fan 48, the blower 36, and the air heater 44 are driven for a preset 60 minutes, The inside of the chamber 2 can be further dried, and the occurrence of mold in the sauna chamber 2 and the propagation of bacteria and the like can be prevented.

  When the ventilation switch 59 is turned on by the user during the stable mode, the ventilation lamp 60 is turned on to start driving the ventilation fan 48. When the counting for a certain time, for example, 1 minute is completed, the ventilation fan 48 is driven. It is to stop. Note that the stable mode is continuously performed while the ventilation fan 48 is driven. As described above, the ventilation switch 59 can be used for the purpose of ventilation in the sauna room 2 in the stable mode, and the ventilation switch 59 can be used for the purpose of drying in the sauna room 2 during the stop state. 59 can be used for both ventilation and drying.

  The present invention is not limited to the above-described embodiment. In the above-described embodiment, the drain trap 14 is built in the sauna device. However, the drain trap 14 is installed outside the sauna device. Even if the drain trap 14 is installed outside the sauna device, the drain trap 14 has the same effect as that built in the sauna device.

  Further, in the stable mode, the ventilation fan 48 is driven for a short time (10 seconds) every predetermined time (10 minutes), but the preset time before the end of the predetermined time, for example, 30 seconds, is set in the sauna room 2. The temperature in the sauna room 2 detected by the room temperature sensor 47 is set temperature + α−0.5 ° C. so that the room temperature becomes slightly higher than the set temperature such as set temperature + α (for example, α = 1 ° C., 2 ° C.). When the temperature is below, the heater 9 is energized, and when the temperature in the sauna room 2 detected by the room temperature sensor 47 becomes equal to or higher than the set temperature + α, the heater 9 is turned off so that the energization to the heater 9 is turned off. Control is performed, or energization of the heater 9 is forcibly started for a preset time before the end of the predetermined time, for example, 30 seconds, and the energization of the heater 9 is continued until the ventilation fan 48 is driven. Sauna By making the room temperature in 2 higher than the set temperature, when the ventilation fan 48 is driven, it is possible to prevent a decrease in room temperature due to ventilation in advance while taking in fresh air, and to perform a comfortable sauna bathing It is.

  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 16 and retained in the warm water of the water storage unit 6 or may adhere to parts such as the rotating body 25 and the porous body 30 in the processing chamber 16, 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.

  In the drying mode, when the drying mode is started and a preset set time has elapsed, the rotating motor 25 and the porous body 30 are rotated by driving the rotating motor 23 for a predetermined operating time only once. When there is no hot water in the water storage section 6 in the mode, the rotation motor 23 may be driven a plurality of times, or the rotation motor 23 may be continuously driven. The motor 23 is driven and the water adhering to the rotating body 25 and the porous body 30 is discharged and scattered, so that the drying of the rotating body 25 and the porous body 30 can be promoted and can be reliably dried. It can be kept clean.
