Description of the Related Art As is well known, a water supply line for cooling equipment such as a boiler, a water heater or a cooler is required to prevent scale adhesion in the cooling equipment, so that the hardness contained in the water is removed. In particular, an automatic regeneration type water softener of a system for removing hardness by using an ion exchange resin is widely used. This type of water softener uses a Na + type ion exchange resin, and replaces metal cations such as Ca 2+ or Mg 2+ contained in water with Na + to remove hardness. When the resin is replaced with cations and becomes saturated and loses the ability to remove hardness, the resin is reacted with salt water to regenerate the ability.

生動作を行う流量再生方式がある。In order to perform the regeneration operation efficiently, the degree of saturation of the ion-exchange resin is detected, and a necessary minimum amount of salt water for regeneration according to the state is supplied. It is desirable to perform the reproducing operation at an appropriate timing. In this case, as a method of detecting and regenerating the degree of saturation of the ion-exchange resin, for example, the amount of raw water flowing through the ion-exchange resin layer (the amount of flow) is measured, and the hardness and the amount of hardness contained in the raw water (generally almost constant) are measured. And the amount of reclaimed water is calculated from
There is a flow rate regeneration method in which a regeneration operation is performed when the flow rate of raw water reaches the calculated regeneration water rate.

In the tap water and the ground water, the hardness of the calcium and magnesium contained in the raw water is not constant, so that the amount of the regenerated water differs. For this reason, when raw water having a high hardness is supplied, the hardness leak detection means provided in the treated water line of the water softener issues an alarm before the raw water flow reaches the predetermined regenerated water flow, and stops the flow operation.

The present invention usually includes a hardness leak sensor or the like as a hardness leak detecting means for softening raw water (hard water) by a flow regeneration method. This is realized in a water softener provided with a hardness leak detecting means. In the regeneration control method according to the present invention, during operation of the water softener according to the flow rate regeneration method, the leaky hardness detecting means detects an integrated flow rate of raw water softened when the leaky hardness is notified, and this integrated flow rate is determined. The ratio between the amount of water and the predetermined amount of regenerated water (normally, the ion exchange resin is automatically regenerated at 100%) is set at a set value (for example, 95%).
%) Or more, it is determined that the capacity of the ion exchange resin is reduced due to variation in the hardness of the supplied raw water, and the ion exchange resin is regenerated. When the ratio between the accumulated water flow rate and the predetermined regenerated water quantity is equal to or less than the set value, it is determined that the ion exchange resin has a hardness leak other than a decrease in capacity (for example, a valve failure of a water softener) and an alarm is issued. To report the hardness leak.
