[0034]

As is apparent from the above description, the present invention increases the surface area of the heat exchange promoting member because the heat exchange promoting member is composed of a plurality of thin plates connected at predetermined intervals. This makes it possible to bring the hot water flowing down to the heat exchange promoting member into contact with the air taken in from the air suction port over a large area, so that the steam generating capability can be increased and the heat exchange promoting member Height dimension can be reduced.

In addition, since each thin plate of the heat exchange promoting member is arranged substantially parallel to the air flow path inside the exterior body forming the steam sauna unit main body,
The flow path resistance can be reduced, whereby the heat exchange in the heat exchange promoting member can be performed smoothly, and a fan having a low capacity can be used. Therefore, noise can be reduced.

According to the second aspect of the present invention, the heat exchange promoting member is formed of an upper thin plate and a lower thin plate, and the number of lower thin plates is made larger than the number of upper thin plates. The contact area between the hot water and the air at the lower part can be made larger than the upper part of the heat exchange promoting member, and the lower part of the heat exchange promoting member by the hot water having a low calorie after the heat exchange has already been performed at the upper part of the heat exchange promoting member. Heat exchange efficiency can be increased.

Furthermore, in the third aspect, the interval between the hot water outlets of the hot water outlet pipe is set to be within three times the interval between the upper thin plates of the heat exchange promoting member. Hot water from the outlet can flow down over almost the entire surface of the thin plate, whereby the heat exchange efficiency can be further improved together with the second aspect.

Still further, in claim 4, the upper portion of the heat exchange promoting member is inclined so as to be located rearward in the outer casing, and the fan unit is disposed on the rear side of the lower portion located forward in the outer casing. Therefore, in particular, the height dimension of the exterior body can be made smaller, and the overall size of the apparatus can be further reduced, so that, for example, the bathroom can be mounted in the bathroom counter. The space can be used effectively.
