下、その構成について図面を参照しながら説明する。2. Description of the Related Art Conventionally, this type of steam generator was developed as shown in Fig. 4.
1-40933. As disclosed in the above publication, water was generally supplied to the steam generator from a water tank by a natural head between the water tank and the steam generator. The configuration will be described below with reference to the drawings.

加熱するバーナである。In FIG. 4, in the steam generator in which a steam heating pipe 45 and a water heating pipe 46 are connected by a steam/water separation tube 47, water is supplied from a tank tank 4B to a water heating pipe 46 via a circulation pipe 49 by natural head. . In the figure, 50 is a burner that heats the water heating tube 46 and the steam heating tube 45.

パクトに収容できない問題点があった。Problems to be Solved by the Invention In such a conventional configuration, when the water heating tube 46 is heated by the burner 50, the water boils and steam of gas-liquid mixture is generated. Then, the gas-liquid mixture is separated in the steam-water separator 4B,
Only the steam is further heated in the steam heating tube 45. In this way, when the water in the steam generator is reduced by evaporation,
When the tank tank 4B or a valve (not shown) provided in the water supply channel is opened to replenish water, the steam pressure of the steam generator is applied to the tank tank 4B, so the tank tank 4B is isolated from the atmosphere. It had to be a closed type. Also,
In a steam generator such as a facial beauty device that applies steam to the face to open the pores and remove impurities, the tank 48 may be small because the amount of water used is small. When the bath is used for bathing, the amount of water is approximately 4,500 cc per person, which increases the capacity of the tank 4B, making the entire device large, and there is also the problem that it must be replenished every time the bath is taken. In addition, if the water tank is an open tank with an automatic water supply system, the steam pressure from the steam generator will be applied to the water tank through the circulation pipe, so the water level in the water tank will have to be considerably higher than the steam pressure (approximately 0.2 to 9 f/cd). Therefore, there was a problem that the water tank and the steam generator section could not be compactly accommodated in the same block.

いる。Here, in order to prevent the room temperature in the bathroom from rising too much due to the continuous generation of steam, a bathroom controller installed in the bathroom etc. is used to operate the capacity control circuit 23 shown in FIG. When the capacity variable 3B is performed, the proportional control valve 13 is controlled by the signal from the capacity control circuit 23, and the proportional control valve control 39 and fuel supply amount control 40 adjust the fuel supply amount and limit the amount of steam generated by heating the heating burner 14. This makes it possible to control the rise in room temperature. In addition, based on the signal from the capacity control circuit 23, the steam generator water level judgment 41 detects the upper limit water level WH and the lower limit water level WL using the water level sensors 11 and 12, and the water supply pump 10 is controlled by the water supply pump control 42 and the water supply flow rate control 43 to control the fuel supply. Continuous steam generation can be obtained by supplying water under pressure at a flow rate proportional to the supply amount and supplying water in proportion to the amount of steam generated by heating. As mentioned above, the water supply pump 10 is connected to the capacity control circuit 23 in the controller 15 so that water is supplied under pressure at a large flow rate when water supply starts, and when steam is generated, water is supplied under pressure at a flow rate proportional to the amount of fuel supplied. The control valve drive circuit 22 and the water supply pump drive circuit 20 are configured to operate.

を持っている。The water supply pump 10 has a pressurized water supply function of recovering the water from the lower limit water level WL to the upper limit water level WH. It has the ability to supply water under pressure at a water supply pressure P that is greater than the steam pressure P□ acting on the heated portion (water) of the steam generator 1.

りエツトサウナ入浴が出来る。However, the capacity of water supply pressure P and water supply amount Q is based on steam pressure PO
If the amount of evaporated water is too large than the maximum water level QO, the recovery time from the lower limit water level WL to the upper limit water level WH will be too short, and the boiling water in the heated area will mix with the low-temperature make-up water, causing the hot water temperature to suddenly drop. This is undesirable since it takes time to raise the temperature to the boiling temperature and the amount of steam generated during this time is significantly reduced. For this reason, the water supply pump drive circuit 20 takes the capacity of the water supply pump 10 into consideration and performs variable capacity control using methods such as voltage control, PWM control, and vvvy inverter control, thereby controlling the water supply pressure P.
If the water supply amount Q is set so as not to exceed the steam pressure p□ and the maximum evaporated water amount Qo, the hot water in the area heated by the make-up water will be mixed with the make-up water, reducing the amount of steam generated when making up the water. This is an effective control method that can reduce the amount. As a result, the water supply pump 10 can be controlled with a water supply flow rate proportional to the fuel supply amount when steam is generated, and can be controlled with a large flow rate when water supply starts, so after turning on the operation switch, the steam generator 1 It is possible to shorten the time for water supply inside the tank, and the rise time until steam generation can be speeded up. In addition, since the temperature rise in the bathroom can be controlled by adjusting the capacity, it is possible to enjoy a comfortable sauna bath.

It is about 1 minute (6000 to 18000 cc/h). In addition, the steam pressure is approximately 0.2 to 0.5 kgf/d because a shutoff valve is not provided in the steam piping route from the steam generator 1 to the steam outlet in the bathroom etc. in consideration of safety during steam generation.
