[0005]
[Problems to be solved by the invention]
In the conventional sauna apparatus as described above, there is no means for exhausting outside, and a separate ventilation means is necessary to dry the inside of the bathroom which has become a humidified space after bathing.
[0006]
Further, since hot water jetted from the hot water outlet 104 is jetted onto the heat exchange promoting member 108 to generate mist, the area of the heat exchange promoting member 108 is required, the exterior body 101 has a vertically long structure, and the ceiling of the bathroom. Since it cannot be stored in the space, the main body is installed in the bathroom. Also, if the apparatus is placed horizontally for storing the space behind the ceiling, the sprayed hot water falls from the heat exchange promoting member 108 while being guided from the heat exchange promoting member 108 to the drain pan 110, that is, falls from the ceiling. Therefore, it is difficult to install it on the back of the ceiling even when it is placed horizontally. For this reason, since the apparatus main body is arrange | positioned in a bathroom, the subject that a bathroom became narrow occurred.
[0007]
Further, since a large amount of hot water flows through the heat exchanger accelerating member 108 to the drain pan 110 and drains to the outside, a drain pipe is necessary, and construction for that is necessary.
[0008]
A part of the hot water jetted on the heat exchange promoting member 108 is supplied to the air as water vapor, but the remaining hot water is drained from the drain pan 110 to the outside. For this reason, there is a problem that the energy held by the hot water cannot be used effectively and humidification cannot be performed efficiently. In addition, there is a problem that the amount of heating water used and the heating amount for raising the temperature of the warm water to a predetermined temperature are increased, and the running cost is increased.
[0009]
In addition, it is unavoidable in terms of structure that a part of the hot water ejected from the hot water outlet 104 may be blown into the bathroom from the steam outlet 103 as fine water droplets. There was a problem.
[0010]
Further, in the sauna apparatus according to the conventional technique as described above, since the hot water is jetted from the hot water outlet 104 onto the heat exchange promoting member 108, when the apparatus is stopped, the heat exchange promoting member 108 and the spouted hot water pipe 104 are provided. A lot of water droplets are attached. In such a state where a large amount of water droplets are attached, there is a problem that mold and fungi tend to propagate and are not preferable for hygiene.
[0011]
Further, since the air sucked from the suction port 102 is very high humidity, the fan unit 109 installed in the air passage has to be used with moisture resistance.
[0012]
The present invention has been made in consideration of the problems of such a sauna apparatus, and can be installed behind the ceiling of a space outside the bathroom, and the growth of mold in the bathroom is suppressed by drying the bathroom after use. In addition, the construction of the drain pipe is simplified, the humidification can be performed efficiently, the running cost is low, the sensation is comfortable, the device can be maintained hygienically, and the components of the intake air passage for humidified air are compatible with normal temperature and normal humidity An object of the present invention is to provide a sauna apparatus that can be used with any of the above components.
