熱するバーナである。BACKGROUND OF THE INVENTION Conventionally, in this type of steam generator, water is supplied to the steam generator from a water tank, as shown in FIG.
Water is supplied from a cassette-type water tank 63 to the water heating pipe 61 via a circulation pipe 64 by natural head to a steam generator in which a steam heating pipe 60 and a water heating pipe 61 are connected by a steam/water separating tube 62. In the figure, 65 is a burner that heats the water heating tube 61 and the steam heating tube 60.

っていた。Furthermore, since the amount of water used is small, drainage is generally not performed to prevent scale build-up within the steam generator. Therefore, no particular drain valve is provided. Furthermore, in a steam generator for commercial use which has a larger water storage capacity than that for home use, steam is generated by heating a large number of water pipes 67 provided around the boiler combustion chamber 66, as shown in FIG. is common, its steam pressure is high,
High pressure pump 6 to supply water with water supply pressure higher than steam pressure
8, and the boiler manager and others regularly opened the drain valve 9 to prevent scale build-up.

クでコン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 61 is heated by the burner 65, the water boils and steam of gas-liquid mixture is generated. Then, the gas-liquid mixture is separated in the steam-water separator 62,
Only the steam is further heated in the steam heating tube 60. In this way, when the water in the steam generator is reduced by evaporation,
When the tank tank 63 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 63, so the tank tank 63 is isolated from the atmosphere. It had to be a closed type. Also,
In a steam generator such as a facial beauty device that exposes steam to the face and opens the injection hole to take out dirt, the tank 63 may be small because the amount of water used is small, but if the tank 63 is small as in the present invention, When the sauna is used by a number of people, the amount of water is approximately 4,500 cc per person, which increases the capacity of the tank 6a, making the entire device large, and there is also the problem that it must be replenished every time the sauna takes a bath. Furthermore, 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 raised considerably to the steam pressure (approximately 0.2 kg i/am2). Therefore, there was a problem that the water tank and the steam generator section could not be compactly accommodated in the same block.

時間が短かい場合、再給水時間に排水時間も付加されて
更に入浴準備時間が長くなる。- After taking a sauna bath, it is preferable to drain the water in the steam generator, which is enriched with Ca, Mg, etc., but it takes time to refill the water and take a long time to prepare for the bath. ■If drainage is not smooth and takes time, and if the time from stopping bathing to re-bathing is short, draining time is added to re-watering time, making bath preparation time even longer.

を持っている。Since 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, the water supply pump 10 has a water supply function that is larger than the maximum amount of evaporated water per unit time o□ during the maximum heating of the heating burner 14. It has the ability to supply water under pressure at a water supply amount Q and 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.

発生量の低減量を少なく出来る有効な制御方法である。However, the capacity of water supply pressure P and water supply amount Q is based on steam pressure Po
If the maximum evaporated water amount QO is too large, the recovery time from the lower limit water level WI to the upper limit water level WH will be too short,
This is preferable because the boiling water in the heated area mixes with the low-temperature make-up water and the temperature of the water drops rapidly, so it takes time to raise the temperature to boiling temperature, and during this time the generation of steam decreases significantly. do not have. Therefore, by taking the capacity of the water supply pump 10 into account and performing variable capacity control using the water supply pump drive circuit 2a, for example, by voltage control, PWM control, VVVF inverter control, etc., the water supply pressure P and the water supply amount Q can be adjusted to steam. If the pressure is set so that it does not exceed the pressure p□ and the maximum evaporated water amount QO, the hot water in the area heated by the make-up water will be difficult to mix with the make-up water, and this is an effective control method that can reduce the reduction in the amount of steam generated during water replenishment. It is.

を短時間にすることが出来る。If you want to take a bath again next time, by setting the operation switch to "priority" again, you can start from the first sequence and supply pressurized water to the water pump 10 at a large flow rate to quickly generate steam. Water supply and drainage are performed for a short time each time you take a sauna bath, to prevent Ca, Mg, etc. contained in the water supply from being heated and concentrated and settling at the bottom of the steam generator 1, and to prevent them from floating and generating the steam. It is possible to prevent scale from adhering to the inner wall of the vessel 1, and to shorten the bath preparation time.

装置も不要となる。In addition, as mentioned above, the water quality of the drainage water is such that scale containing a large amount of Ca1Mg etc. tends to settle and adhere to the water, so the purpose is to prevent clogging of the drainage channel 18 and the drain pipe 20 due to scale adhesion as much as possible. It is desirable to mix the water in the open water supply tank 2 with the water in the open water supply tank 2 to reduce the concentration before draining the water.For this purpose, the water drained from the drainage channel 18 and the hot water in the steam generator 1 are passed through the water supply channel 9. The drain channel 18, the drain valve 19, and the drain pipe 20 are configured so that the water can be drained after mixing. Then, at the same time as lowering the water quality concentration, the boiling water in the steam generator 1 (
The temperature of the waste water can be lowered by mixing the water in the open water tank 2 with the water in the open water supply tank 2, thereby preventing the danger of directly draining the water (high temperature water).
It is also possible to lower the allowable temperature limit. Furthermore, since all the water in the device is drained, there is no need for anti-freezing devices when the temperature drops, such as in winter.
