In addition, the water droplet collecting means 3 is provided with an air-water heat exchanger 8 having a duct for circulating the heat medium and a plurality of heat transfer plates for efficiently transferring the heat of the duct to the air. The air-water heat exchanger 8 is circulated by circulating hot water circulated by a heat source unit (not shown) in a pipe line through which the heat medium is circulated. It can also be used as air heating means 107 for heating the air circulated by the fan 106. Further, the water heating means 4 uses hot water circulated by a heat source unit (not shown) as a heating medium, like the air heating means 107, and water-water heat that heats the supply water in the water supply pipe 4 with this hot water. The exchanger 9 is provided. The hot water circulated by the heat source device is piped so as to circulate by being divided into each of the air-water heat exchanger 8 and the water-water heat exchanger 9 by the hot water pipe 10. Thermally operated valves 109a and 109b for interrupting the circulation are provided. Further, the water supply pipe 4 is also provided with a solenoid valve 113 for intermittently supplying the water supply to the ejection nozzle 111. Further, the drainage means 5 drains water droplets existing between the circulation fan 106 in the circulation air passage 105 and the air-water heat exchanger 8 together with the relatively large droplets collected by the waterdrop collection means 3 to the outside of the main body 101. It is configured as follows. Specifically, the circulation path 105 positioned downstream of the circulation fan 106 in the air flow direction is formed with a downward slope, and the inner wall is curved so that water droplets adhering to the inner wall of the circulation air path 105 are smoothly dropped downward. The outer peripheral surface of the main body 101 located at the lowest point of the downward slope is opened, and the drain hole 11 for draining water droplets to the outside of the apparatus is provided.

  Next, the operation of the above configuration will be described. When an operation instruction is given from a controller (not shown), the circulation fan 106 is activated, a thermal valve 109 a provided in the hot water circulation path of the air-water heat exchanger 8, and hot water of the water-water heat exchanger 9. The thermal valve 109b and the electromagnetic valve 113 provided in the circulation path are opened, and hot water from a heat source unit (not shown) is circulated by being divided into the air-water heat exchanger 8 and the water-water heat exchanger 9, and water is supplied. Water is supplied through the pipe 6. Supply water from the water supply pipe 6 is heated by heat exchange with one of the hot water circulated by a heat source unit (not shown) in the water-water heat exchanger 9. The heated supply water is supplied to the ejection nozzle 111 and ejected in a high temperature mist state and collides with the circulation fan 106. The mist that has collided with the circulation fan 106 is forcibly crushed by the rotation of the circulation fan 106, becomes fine high-temperature water droplets, is contained in the air in the sauna target chamber 103 blown by the circulation fan 106, and is an air-water heat exchanger. 8 is supplied. The air-water heat exchanger 8 is used to efficiently transmit heat to the supplied air from the pipe through which the other of the hot water circulated by a heat source unit (not shown) flows, and the hot water flowing through the pipe. The air containing a plurality of heat transfer plates and containing fine high-temperature water droplets supplied to the air-water heat exchanger 8 is heated through heat exchange with the hot water via the plurality of heat transfer plates. At the same time, when passing through the gaps between the plurality of heat transfer plates, relatively large water droplets are collected from the water droplets contained. In this way, the air-water heat exchanger 8 functions as both the water droplet collection means 3 and the air heating means 107. The hot water after heat exchange with air in the air-water heat exchanger 8 joins the hot water after heating the feed water in the water-water heat exchanger 9, and then circulates back to a heat source unit (not shown).

By repeating the above operation, fine water droplets that have not been recovered by the water droplet recovery means 3 among the high temperature water droplets generated by the water crushing means 2 are continuously supplied to the sauna target chamber 103. Since the sauna target room 103 is heated by being heated by the air heating means 107 while being humidified without the feeling of water droplets and the feeling of cold air and being circulated by the circulation means 1, the sauna target room 103 is heated. 103 becomes a high-temperature and high-humidity sauna space without a water drop feeling and cold wind feeling.

  When the temperature of the sauna target room 103 is to be lowered, the hot water circulation to the air-water heat exchanger 8 is interrupted by closing the thermal valve 109a, and the sauna target is circulated by the circulation means 1. This can be dealt with by reducing the heating amount of the air in the chamber 103.

  Further, when there is no need to suppress the feeling of cold air due to humidification of the sauna target room 103, the thermal valve 109b is closed to block the circulation of hot water to the water-water heat exchanger 9, and the water crushing means This can be dealt with by reducing the heating amount of the feed water to 2.

As a result, the user can comfortably spend in the sauna target room 103 without feeling a drop of water, and the user's view is not obstructed by the mist. Moreover, fine water droplets can be generated by further crushing the mist ejected by the mist ejecting means 110 with the mist crushing means 7. Thereby, the water crushing means 2 can be made into the simple structure by the mist ejection means 110 and the mist crushing means 7. FIG.

  Further, when the mist ejecting means 110 ejects the mist toward the circulation fan 106 of the circulation means 1, the mist is forcibly broken by the rotation of the circulation fan 106, and finer water droplets can be generated. As a result, fine water droplets can be supplied to the sauna target chamber 103 to humidify without feeling water droplets, and the water crushing means 2 is configured using a part of the circulation means 1 for circulating the air in the sauna target chamber 103. Therefore, the apparatus can be reduced in size.

  Further, the drainage means 5 drains the relatively large water droplets collected by the water droplet collection means 3 to the outside of the apparatus, so that the ventilation path of the circulation means 1 is blocked by the retention of the relatively large water droplets collected by the water droplet collection means 3. Can be suppressed. Thereby, the air volume of the circulation means 1 is securable appropriately.

  In addition, the drainage means 5 drains the water drops present in the path between the water crushing means 2 and the water droplet collection means 3 to the outside of the apparatus, so that the water drops present in the path between the water crushing means 2 and the water drop collection means 3 are removed. Blockage of the path due to retention can be suppressed. Thereby, the air volume of the circulation means 1 is securable appropriately.
