御器８により再びポンプ４の運転を停止させる。When the operation switch of the controller 8 is turned on, when the water level of the water tank 1 reaches WO as described above, the pump 4 is driven by the controller 8 that receives this signal, and the water tank 1 is supplied from the water supply pipe 3. When water is supplied to the steam generator 2 through the water supply port 13 and reaches the water level wH of the water level electrode 14, the controller 8 receives this signal and stops the pump 9, and the burner 6 starts combustion. Start. When the water stored in the heated part 16 at the lower part of the steam generator 2 is heated by the burner 6 and boils, the water turns into steam and fills the steam chamber 17, and the steam is supplied to the sauna room from the steam volume lower. When steam is generated one after another, the water that has changed to steam decreases from the heated part 19, so the water level decreases from wH, and when the water level of the lower water level electrode 15 falls below the water level WL, this signal is received. The pump 4 is driven again by the controller 8, and the heated portion 16 is replenished with water from the water tank 1 to recover the water level wH. Then, the controller 8 receiving the signal from the water level electrode 14 stops the operation of the pump 4 again.

蒸気発生の低減量を少なくできる。Since the water supply pump 4 has the water supply performance of recovering the water level from WL to wH, the maximum amount of evaporated water per unit time Q when the device is at maximum heating of the burner 6
It also has the ability to supply water at a large amount of water Q and at a water supply pressure P that is greater than the pressure Pa acting on the heated portion 16 of the steam generator 2. However, if the performance of the water supply pressure P and the water supply amount Q is too large compared to the pressure Po and the maximum evaporated water amount Qo, the recovery time from the water level WL to wH will be too short, and the water in the heated part 16 will become low. This is not preferable since it mixes with make-up water at water temperature and the water temperature drops rapidly, so it takes time to raise and heat the water temperature to boiling temperature, and during this time the generation of steam decreases significantly. For this reason, if the water supply pressure P and the water supply amount Q are set to be as low as possible than the pressure PO and the maximum evaporated water amount Qo, taking into account the performance variations of the pump 4, etc., the water in the heated part 19 by makeup water can be It is difficult to mix with water, and the amount of reduction in steam generation during water replenishment can be reduced.

c/min. In addition, the steam pressure can be reduced to 0 or 0, since no shutoff valve is provided in the passage of steam from the steam generator 2 to the steam outlet of the sauna room in consideration of the safety of steam generation.
Since it is about 2 to 0.59 pages Kg f A1n2, a small pump 4 may be selected. However, during steam generation, the steam pressure of the steam generator 2 is always applied to the water tank 1 via the pump 4, so
A check valve 5 is provided in the water supply pipe 3 to prevent steam pressure from being applied directly to the water tank 1 when steam is generated by the steam generator 2.
