  Next, a block diagram of the main electric circuit of the mist generating means shown in FIG. 9 will be described. On the input side of the microcomputer 51 having functions such as storage, calculation, and time counting, an ON / OFF operation switch 52, Float switches 35 and 36 are connected to a hot water storage temperature sensor 39 and a heating prevention sensor 40. On the output side, an automatic water supply valve 7, a heater 10, an automatic drain valve 12, and a rotation motor 19 are connected. The blower 32 and the air heater 38 are connected, and the blower 32 and the air heater 38 are energized for 10 minutes at the start of operation and the count of the drying operation for 90 minutes at the end of the operation is controlled by the count by the microcomputer 51. Is.

Next, the operation of this embodiment will be described.
By turning on an operation switch 52 of an operation unit (not shown) provided in the vicinity of the sauna room 2, the sauna operation is started. First, the automatic water supply valve 7 is opened, and the water storage unit 6 in an empty state from the water supply pipe 8 is opened. When the water is supplied to the water level and stored (6L) to a certain level, the water level sensor 34 detects and the automatic water supply valve 7 is turned off to terminate the water supply. Automatic water replenishment is performed.

  At this time, as shown in the flowchart of FIG. 10, when the operation switch 52 is turned on in step 53, the blower 32 and the air heater 38 are energized in step 54 by the output from the microcomputer 51, and the suction duct 4 is passed through. The air in the sauna chamber 2 sucked in this way is heated, passes through the water storage section 6 from the treatment chamber 15, passes through the separation chamber 16, is returned to the sauna chamber 2 from the discharge port 5, and is stored in the sauna chamber 2 at the start of operation. The temperature rises and the rise time is shortened. In step 55, when 10 minutes have elapsed since the operation switch 52 was turned on, in step 56, the energization of the blower 32 and the air heater 38 is turned off. The heating operation is stopped.

  Next, the heater 10 is turned on to start the warming of the water in the water storage section 6, and when the stored water reaches 30 ° C. where the temperature has risen to some extent, the rotation motor 19 starts to drive and once 10 minutes have passed. The stopped blower 32 starts to drive again, and the rotating body 21 rotates in the processing chamber 15, so that the front and back surfaces of the lower end that are submerged are more and hot water is centrifugal force and rises along that surface. However, water particles are scattered from the plurality of pores 22 at the upper end toward the outer periphery, and some of them collide with the rotating porous body 26, and the water particles are crushed. By passing through and colliding with the inner wall of the air guide tube 28 around the porous body 26 and crushing the water particles, mist containing nano mist and large mist is generated, and the crushing of the particles makes the air negative. Electrified Nasuion occurs. Moreover, the warm water in the water storage part 6 is also stirred to some extent, and has the effect of making the whole temperature uniform.

  On the other hand, air in the sauna chamber 2 flows from the air supply port 33 through the suction duct 4 by driving the blower 32, and is guided to the air guide cylinder 28 from above the rotating rotator 21 and into the processing chamber 15. At this time, a pair of large flow passages 29, 29 and a pair of small flow passages 30, 30 are formed between the cylindrical porous body 26 and the elliptical air guide tube 28, By circulating air here, a pressure difference is generated from Bernoulli's theorem, and the flow of air from the high flow passage 29, 29 side where pressure is high to the small flow passage 30, 30 side where pressure is low is generated and turbulent flow occurs. Large mist easily falls and only fine nano mist exists, and a lot of air comes into contact with negatively charged water particles, so that a large amount of negative ions can be obtained. When the dust and bacteria contained in the air Was dropped into water is surrounded by more than mist Nanomisuto, that it remains in the water, but also air cleaning are performed simultaneously, the air purifier are intended to be performed satisfactorily become air turbulence.

  Furthermore, the air that rises in temperature due to hot water mist and contains negative ions is a downward flow that passes through the communication passage 17 below the partition wall 14, and the large mist falls into the water under its own weight and rises in the subsequent separation chamber 16. The mist of nano mist or more remaining in the process of hitting first hits the first baffle plate 23 at the lower end of the partition wall 14 and grows and falls into a large mist, and then falls while circulating through the meandering path 25. That hits the baffle plate 24, grows and drops into the last large mist, circulates through the meandering path 25 again, and finally is discharged from the discharge port 5 into the sauna room 2 through the blower 32 It is.

  As a result, the release of large mist is surely prevented, and only the ultrafine nano mist and negative ions due to negatively charged air are released from the discharge port, so there is no worry about the floor and walls being painted, and it can be used with confidence. A good atmosphere full of nanomist and negative ions can be formed.

  At this time, the water surface in the water storage section 6 undulates due to the rotation of the rotating body 21. However, since the water level sensor 34 is surrounded by the protective frame 37 extending on the water surface, waves are generated on the water surface in the protective frame 37. Accurate water level detection is not carried out, and there is no problem that the automatic water supply valve 7 causes chattering. Negative ions and nanomist generated by the rotating body 21 can be generated satisfactorily at a set constant water level, and the discharge space is comfortable. It can be held in the atmosphere space.

  Further, the water level sensor 34 is composed of two float switches 35 and 36, so that even if the stroke is short, there is no fear of malfunctioning, and the automatic water supply valve 7 can be accurately controlled to control the automatic water supply valve 7. It can always be maintained at a constant water level without excess or deficiency.

  In addition to direct waves from the front, secondary waves that hit the side wall of the water storage section 6 and act on the water level sensor 34 can be blocked by the frames on both sides, so that the influence of the waves can be completely blocked. The water level sensor 34 is firmly protected and can be used safely for a long time.

  Furthermore, if this is a low temperature sauna, the temperature in the sauna room 2 is gradually raised by a circulation method, and a room temperature of 38 ° C. to 40 ° C. in 30 minutes and a low temperature sauna use atmosphere full of negative ions with a relative humidity of 90% or more with nano mist, Bathing for more than 20 minutes is possible, and water molecule-added negative ion molecules act directly on the skin and open the sweat glands, making it easier to sweat and sweating away the waste products in the body. In addition, negative ions sucked from the lungs enter the blood, and their reduction action prevents the oxidation of the blood to make it smooth, and improves circulation and spreads blood to the peripheral blood vessels. It is thought that discipline can be eased.

  In addition, negative ions have fatigue recovery effects, mental stability effects, blood purification effects, resistance enhancement effects, autonomic nerve adjustment effects, etc., and nano mist spreads to every corner of the air to suppress dirty air and bacteria. However, it still decomposes and has a deodorizing effect, dust removing effect, disinfecting effect, and of course a humidifying effect. This humidification is smooth and moist air with no stickiness, and it penetrates through the pores. It has the effect of keeping the hair moisturized, and the release of a large amount of negative ions and nanomist capable of obtaining these effects also increases these effects.

  On the other hand, when the relative humidity in the sauna room 2 is 90% or more, dew condensation water is generated on the ceiling, the wall surface, and the open / close door 42 of the sauna room 2. Every time the open / close door 42 is opened to enter and exit, the condensed water adhering to the indoor side wall surface slips down, and the floor surface outside the entrance is contaminated. The condensed water adhering to the indoor side wall surface of the open / close door 42 of the sauna room 2 gradually increases with time, and eventually slides down on the wall surface of the open / close door 42 by its own weight. Since the upper surface of the inner stepped portion 47 facing the bottom of the indoor side wall surface is an inclined surface 46 that is inclined downward toward the sauna chamber 2, the dropped droplets flow down into the sauna chamber 2 along the inclined surface 46. Also, an inverted L-shaped notch at the bottom of the open / close door 42 The droplets that try to flow back to the outer step 45 through the gap between the inner step 47 and the inner step 47 are blocked by the plate-like packing 50 and returned to the flow along the inclination of the normal inclined surface 46, so The dripping onto the floor surface in front is prevented, and the floor surface can be reliably prevented from being soiled.

  4 and 5, the horizontal portion of the cutout 48 is formed as an inclined portion A so that the side of the sauna chamber 2 is lowered, or a droplet wrap-around prevention wall B is provided at the end of the cutout 48. By providing this, it is possible to prevent the wraparound of the drop and further prevent the drop on the floor surface.

  The floor in front of the entrance of the sauna room 2 does not get dirty, and it does not require much time for wiping and cleaning. Especially in the case of the assembly type sauna room 2 installed in an existing house, the installation room is waterproofed. Therefore, preventing dripping of condensed water has a great effect.

  Next, in the drying operation after the sauna operation, as shown in the flowchart of FIG. 11, when the operation switch 52 is OFF (step 57), the process proceeds to step 58 with YES, and the automatic water supply valve 7 of the water supply pipe 8 is turned on by the output from the microcomputer 51. It is in a closed state, the heater 10 is turned off, the rotation motor 19 and the blower 32 are stopped, the automatic drain valve 12 is opened, all the remaining water in the water storage section 6 is drained from the drain pipe 13, and the sauna is opened. The operation ends. In step 59, 10 seconds after the operation switch 52 is turned off is counted and confirmed, and then the drying operation is started. In step 60, the blower 32 and the air are output by the output from the microcomputer 51. The heater 38 is energized to suck air containing nano mist in the sauna chamber 2 from the suction duct 4, and this air is inclined and attached to the air inlet 33. Heated by the heater 38 to generate hot air, which is sequentially supplied from the processing chamber 15 to the empty water storage section 6, and not only the water storage section 6 but also the processing chamber 15 and the separation chamber 16 are dried, and mold and bacteria The drying operation is performed for 90 minutes and is automatically turned off (steps 61 and 62). During this period, the drying operation is performed. Since the hot air is discharged into the sauna room 2, the sauna room 2 is also automatically dried and has an effect of maintaining a good state.

  The air heater 38 is formed in an inverted U-shape and protrudes from the side wall of the air supply port 33 so as to be inclined with respect to the side wall, so that the air heater 38 can be mounted compactly without taking up space. The apparatus can be easily installed in the sauna room 2 without increasing its size, and the single air heater 38 can be used for heating the sauna room 2 as well as drying the apparatus. It can be used well.

  Furthermore, since the hot water heated by the inverted U-shaped portion 9 of the heater 10 and heated to the upper part flows into the upper part where the lower part of the rotating body 21 is submerged, the hot water is immediately sucked up by the centrifugal force generated by the rotation of the rotating body 21, The nano mist is generated by crushing against the porous body 26, and the air passing through the crushing is negatively charged. At the same time, negative ions are also generated. The water by the heater 10 is heated to some extent. From the early stages, nano mist and negative ions are generated and supplied to the sauna room 2 to reduce the waiting time and make the sauna room 2 ready for use in a short time. You can enjoy a low temperature sauna.

  Furthermore, since there are three inverted U-shaped portions 9 of the heater 10, there is a degree of freedom in the mounting position of the rotating body 21, and the same effect can be obtained regardless of where the rotating body 21 is mounted. Good effect can be obtained without being affected by cold water the further away.
