2. Description of the Related Art In order to maintain mist formation in a sauna space in an appropriate state, it is desirable to maintain the supply pressure or supply amount of hot water to the mist nozzle within an appropriate range. Therefore,
Conventionally, as disclosed by the present applicant in Japanese Patent Application No. 1-234217, a hot water is supplied to a mist nozzle even if the source supply pressure of the hot water is low by providing a pressure pump between the supply means and the mist nozzle. The supply pressure or supply amount was set to exceed the appropriate lower limit value.

[0003]

In the above-mentioned prior art, when the original supply pressure of the hot water is high, the supply pressure or the supply amount of the hot water to the mist nozzle becomes higher than necessary. As a result, the mist spray amount becomes excessively large, and the mist nozzle spray noise becomes loud, which may rather cause the user to feel uncomfortable. An object of the present invention is to solve the above-mentioned conventional drawbacks and to provide an appropriate mist sauna device with excellent comfort by making the supply pressure or supply amount of the hot water to the mist nozzle appropriate regardless of the original supply pressure of the hot water. In point.

[0004]

To achieve this object, the mist sauna device according to the present invention is characterized by a detecting means for detecting the supply pressure or supply amount of hot water to the mist nozzle, and the supply pressure or supply. An adjusting means for adjusting the amount and a control means for controlling the operation of the adjusting means so that the supply pressure becomes a predetermined pressure or the supply amount becomes a predetermined amount based on the information of the detecting means are provided. Is.

[0005]

The proper supply pressure or the proper supply amount of the hot water to the mist nozzle is set as the predetermined pressure or the predetermined amount, respectively. Therefore, the supply pressure or the predetermined amount of the hot water to the mist nozzle can be appropriately maintained regardless of the original supply pressure of the hot water.

[0006]

Since the supply pressure or the predetermined amount of hot water to the mist nozzle can be properly maintained, the mist spray amount can be properly maintained and the mist nozzle spray noise can be suppressed. Therefore, the comfort of the mist sauna device can be enhanced.
