構成であった。BACKGROUND OF THE INVENTION Conventionally, as shown in FIG. 4, this type of steam generator is directly connected to a water pipe 4 and has a water supply valve 3 to control the water level to a constant level.
An open type water supply tank 2 provided with a steam generator 1 that boils water to generate steam, and a steam generator 1 and the open type water supply tank 2 are connected, and water is supplied to the steam generator 1 in the middle. The configuration was such that it was equipped with a water supply channel 9 having a water supply pump 10 and a control v416 for driving the water supply pump 1o to operate the heat source 14 and continuously generate steam from the steam outlet 17.

揮出来なくなることがあった。In such a configuration, steam can be continuously generated by the operation of the heating source, but when water is supplied, most of Ca, Mg, etc. contained in tap water remain in the steam generator 1, During long-term use, Ca and Mg gradually concentrate and become extremely concentrated hard water, which adheres as scale to the steam outlet 17 of the steam generator 1 and the inner wall of the steam generator 1, and prevents the heat of the heating source 14 from being absorbed sufficiently. Heat exchange was no longer possible, the amount of steam generated gradually decreased, and the steam piping became clogged due to the adhesion of strands, making it impossible to perform its function as a steam generator.

る。Therefore, as shown in FIG. 6, the tap water is passed through a cannonball-shaped airtight container connected to a water pipe 66 and containing an ion exchange resin 57a, so that the carbon contained in the tap water can be removed.
A method has been adopted for commercial equipment, etc., in which a water softener that softens water by removing a and Mg is connected to the steam generator 1 and water is supplied to prevent scale adhesion on the inner wall of the steam generator. In the figure, 5 is a water supply pipe, 6.7 is an upper and lower water level sensor of the water supply tank 2, 8 is an overflow pipe, 11.12 is an upper and lower limit water level sensor of the steam generator 1, and 13 is a fuel valve. .

置を家庭用に積極的に普及するには難しい面があった。In this way, a water softener that is directly connected to the water supply is a device that is directly connected to the water supply.
The structure must be able to withstand high water pressure; in particular, the container must be shaped like a cannonball to ensure pressure resistance, and be made of expensive materials such as stainless steel to ensure corrosion resistance when exposed to water. This necessitates an expensive water softener 58, which requires a thicker wall, making it difficult to actively popularize steam generators for steam saunas for home use.
また、軟水器のイオン交換樹脂も通過給水量が増えてく
ると軟水化能力も低下するため、定期的に洗浄、再生を
必要とするが、その作業が複雑であシ、家庭用の機器等
には不向きであった。In addition, the water softening ability of the ion exchange resin in a water softener decreases as the amount of water passing through it increases, so it needs to be regularly cleaned and regenerated, but this work is complicated, and household equipment, etc. It was not suitable for

When the ion exchange resin 19 on which Mg and the like are adsorbed is washed with saline etc., the adsorbed Ca and Mg are replaced by the Ha ions in the saline, returning to the original ion exchange resin. After adding salt from the top 48, when the regeneration switch (closed) is turned on, the regeneration control circuit 30 operates, and the water tank water level judgment 49 turns the water supply valve "open" 50 and the water supply valve "closed" 61. Supply tap water repeatedly. By operating the drain valve drive circuit 31 with the drain valve "open" 52 to open the drain valve 20, the ion exchange resin 19 is washed with saline.

とが出来る。An orifice is provided in the drain valve 20, and the drain amount is set to V;t.
Because the saline solution passes uniformly through the 19 layers of ion exchange resin, it is easy to replace Ca, Mg, and Na, and the preset regeneration time timer ends at 5.
3, the water supply valve is "closed" and the drain valve is "closed" 54, and the regeneration is completed 55. Once the regeneration is completed, the ion exchange resin 19 can be operated again, and the ion exchange resin 19 can be used semi-permanently, making it possible to construct a steam generator without scale deposition.
こうすることによって、イオン交換樹脂１９を自動的に
再生が出来るので、家庭用の機器としても有効なものと
なる。By doing so, the ion exchange resin 19 can be automatically regenerated, making it effective as a household device.

能力を持っている。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 maximum amount of evaporated water Qo per unit time during the maximum heating of the heating burner 14 is also reduced. It has the ability to supply pressurized water with a large water supply amount Q and with a water supply pressure P that is also greater than the steam pressure P□ acting on the heated portion (water) of the steam generator 1.

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 amount of evaporated water is too large than the maximum evaporated water amount 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 to suddenly drop. Since the temperature decreases, it takes time to raise the temperature to boiling temperature, and during this time the generation of steam decreases significantly, which is not preferable. For this reason, the water supply pump drive circuit 25 takes the capacity of the water supply bonder 10 into account and performs variable capacity control using methods such as voltage control, PWM control, and vvvr inverter control, thereby controlling the water supply pressure P.
If the water supply amount Q is set so that it does not exceed the steam pressure PO and the maximum evaporated water amount Qo, the hot water in the area heated by the makeup water will be difficult to mix with the makeup water, and the amount of reduction in the amount of steam generated during water replenishment will be reduced. This is an effective control method that can be done with less power.

給水ポンプ１０の選定は小型のものでよい。In general, when steam is ejected into a home bathroom, shower room, or sauna room and used as a wet sauna, considering the width of the bathroom (approximately 3.3 m), the amount of water vapor per unit time is The evaporation amount is 100~30oCCZ
(8000=18000cc/h). or,
The steam pressure is also determined by steam generator 1 in consideration of safety during steam generation.
Since a shutoff valve is not provided in the steam piping route leading from the steam outlet to the steam outlet in the bathroom, etc., the water supply pump 10 can be selected to be a small one, since the water pressure is about 0.2 to 0.5 kg/d.

とを防止することが望ましい。However, during steam generation, the steam pressure of the steam generator 1 is always applied to the open water supply tank 2 via the water supply pump 10, so depending on the resistance to reverse pressure when the water supply pump 10 is stopped, check valves etc. may be required. It is desirable to have it built into the water supply pump 10 or to provide it in the middle of the water supply channel 9 to prevent steam pressure from directly reaching the open water supply tank.

It can be compactly accommodated up to approximately the same level as the upper limit water level wH.

１も小型で良い。In general, the bathing time of a wet sauna is about 10 to 15 degrees per bath under normal usage conditions, and in the winter, a maximum of 300cc/min x 15 minutes = 4.500cc of water is pumped from the steam generator 1. All you need to do is steam, so use steam generator 1.
The amount of water stored in the heated part is the same as when the amount of combustion heat of the heating burner 14 is 1.
Since 0,000 to 13,000 kcal/h is sufficient, a capacity of approximately 500 to 10,000 C is sufficient, and the steam generator 1 may also be small.
