て行うことを可能にした給水装置を対象としている。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an improvement of a water supply device including a water supply tank and a water supply pump, and relates to a boiler, a water heater or a cooler connected to a downstream side. The target is a water supply device that enables stable water supply to external equipment.

るように給水ポンプを制御する機能を備えている。Generally, a water supply device for cooling and heating equipment such as a boiler, a water heater, or a cooler supplies raw water from a raw water supply side to a water supply tank by a water supply pump and temporarily stores it, Water is supplied from the water supply tank to the cooling / heating equipment (external equipment). Such a water supply device has a function of controlling the water supply pump so that the amount of stored water in the water supply tank is always within a predetermined range.
尚、前記給水装置が、特に、冷熱機器類の給水装置と
して用いられる場合、給水ポンプと給水タンクとの間に
適宜の水処理装置が接続されるが、この水処理装置は、
前記冷熱機器類におけるスケール付着防止並びに腐食防
止のためのものである。Incidentally, when the water supply device is used as a water supply device for cooling and heating equipment in particular, an appropriate water treatment device is connected between the water supply pump and the water supply tank.
The purpose of this is to prevent scale adhesion and corrosion in the cold heat equipment.

め、この外部機器に連なる各装置、生産ライン等に悪影
響を与える。By the way, in the conventional water supply device as described above, due to a failure of the water supply pump, a failure or deterioration of the water treatment device on the downstream side of the water supply pump, the water supply capacity into the water supply tank may be lower than usual, or the external Equipment (boiler, water heater,
When the load on the cooling / heating equipment such as a cooler etc. is high and the amount of water used increases suddenly than usual, the water level in the water tank may drop, and eventually water supply from the water tank may be interrupted. . At this time, the external device forcibly suspends its operation due to its own safety function, which adversely affects each device connected to the external device, the production line, and the like.
例えば、水処理装置(D)が、逆浸透膜等の半透膜を

理能力の回復までに時間を要し、上述問題は、重大なも
のとなる。For example, when the water treatment device (D) uses a semi-permeable membrane such as a reverse osmosis membrane, the increase in treatment capacity is expensive, and therefore, there is usually little difference in treatment capacity with respect to the amount of water supplied. Therefore, when such a water treatment device (D) is used, if the treatment capacity is deteriorated due to deterioration of the semipermeable membrane or clogging, the above-mentioned problem occurs. Moreover, in this type of water treatment device, a decrease in the treatment capacity due to clogging can be dealt with by the cleaning work, but if the deterioration of the semipermeable membrane itself is dealt with by the replacement work, the treatment capacity can be improved. It takes time to recover, and the above-mentioned problems become serious.
前記の如き障害は、大容量の給水タンクを用いれば防

となるのは一時的なものであるため、大容量の給水タン
クを用いることは、コストの増大、並びに設置スペース
の増大を招く。The above-mentioned obstacles can be prevented by using a large-capacity water supply tank, but the water supply tank has a required capacity set from the relationship between the maximum amount of water used by an external device and the amount of water supplied to the water supply tank. Since the maximum amount of water used by the external device is temporary, the use of a large-capacity water supply tank causes an increase in cost and an increase in installation space.
