Description

  The present invention relates to a sauna apparatus that makes a sauna target room a high-temperature, high-humidity sauna space.

  Conventionally, a sauna device with a mist function using a bathroom is known as this type of sauna device (see, for example, Patent Document 1).

  Hereinafter, the sauna apparatus will be described with reference to FIGS.

  As shown in the figure, heated air blowing means 102 for blowing air heated by a heating means 101 for heating air, humidifying means 103, and humidified air blowing means 104 for blowing humidified air humidified by the humidifying means 103. And the inlet 105 and the outlet 106, the heated air from the heated air blowing means 102 and the humidified air from the humidified air blowing means 104 are merged before the outlet 106, and the heated humidified air is supplied from the outlet 106. It is configured to blow out.

Further, the humidifying means 103 collides the water supply means 107 for supplying water or hot water, the injection means 108 for injecting water or hot water supplied from the water supply means 107, and the water or hot water injected by the injection means 108. The water crushing means 109 for crushing and the water droplet group supplied by the water crushing means 109 are separated into large water droplets and fine water droplets, and the gas-liquid separation means 110 for collecting the large water droplets. .

  In such a conventional sauna apparatus, it is divided into the heated air blowing means 102 and the humidified air blowing means 104, and the structure is complicated with many parts and two air paths.

  In addition, since the air passage through which the humidified air is blown is narrow and the gas-liquid separation means 110 installed in the air passage is also small, some of the large water droplets ejected from the ejection means 108 are collected by the gas-liquid separation means 110. There was a problem of passing through without being blown out from the air outlet 106. Further, there is a problem that water droplets fall from the air outlet 106 due to the large water droplets adhering to the wall surface of the air passage near the air outlet 106.

  The present invention solves such a conventional problem, and enlarges the gas-liquid separation means by enlarging the air passage as one air passage, and installs the gas-liquid separation means inclined toward the humidifying means. As a result, the distance that the water droplets pass through the gas-liquid separation means can be lengthened, and the water droplets collected near the downstream side of the gas-liquid separation means can be blown out by falling along the inclined surface of the gas-liquid separation means. Because it is guided to the water storage unit without being wetted, the user can spend comfortably in the sauna target room without feeling the water drop by humidifying the sauna target room without feeling the water drop with fine water droplets An object of the present invention is to provide a sauna device that allows a user to enjoy video and reading in a sauna target room without the user being obstructed by the mist.

  In the above configuration, a filter obtained by processing a resin wire as shown in FIG. 10 into a sponge shape is usually used as the gas-liquid separating means 5 in such a sauna apparatus. Although it is difficult to fix so as not to be fixed, a plurality of bosses 10 are provided on the lower surface 11 of the water storage section and the upper surface 12 of the ventilation path, and the gas-liquid separation means 5 is inserted and fixed so as not to move easily in the vertical direction. Therefore, the gap between the gas-liquid separator 5 and the ventilation path 8 can be prevented with a simple structure, and large droplets can be prevented from directly blowing out from the gap.

  Further, since the gap between the gas-liquid separation means 5 and the air passage side surface 14 is closed by the rib 13, the water droplets ejected from the nozzle 4a surely pass through the gas-liquid separation means 5 and large droplets are collected. As a result, air with higher humidity can be supplied without being affected by assembly variations at the time of manufacture.

  In addition, since the water storage section 6 is provided with the fixing plate 15 that can be installed by tilting the gas-liquid separation means 5 in the direction of the humidification means 4 and floating from the lower surface 11 of the water storage section, the water storage volume of the water storage section 6 is secured, By not bringing the recovered waste water into contact with the gas-liquid separation means 5, the ventilation of the circulating air blowing means 2 is improved, and the gas-liquid separation means 5 and the water storage part 6 are easily dried, thereby efficiently with a minimum water storage volume.
