Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ionized water producing apparatus for producing ionized water, which effectively removes calcium components in order to prevent clogging due to calcium deposition and deterioration of electrolytic performance. It is about technology.

[0002]

2. Description of the Related Art Conventionally, an ionized water producing apparatus for producing ionized water is known from JP-A-6-165984. This Japanese Patent Laid-Open No. 6-165984 discloses a method of electrolyzing water to be supplied in an electrolyzer to generate ionic water. The amount of electricity of electrolysis current, the flow rate of supply water, or the integrated value of electrolysis time or a combination thereof is used. Each time the signal reaches a set value, a switching signal is applied to the polarity switch to switch the polarity of the electrolytic cell so that calcium deposits and deposits in the electrolytic cell are removed. Then, in this conventional example, the reference set value of the control circuit for measuring the concentration of calcium in the water to be supplied by the sensor and applying the switching control signal to the polarity switching device for switching the polarity of the electrode of the electrolytic cell according to the measurement signal of the sensor. I am trying to change.

[0003]

However, in the above-mentioned prior art, the polarity is switched to remove the deposits of calcium and other impurities, and the deposits of calcium are directly removed. It was not dissolved by a scavenger, and therefore calcium was not sufficiently removed. Also, the polarity is switched every time the amount of electricity of the electrolysis current, the flow rate of the feed water, or the integrated value of the electrolysis time or the signal of these combinations reaches the set value. The amount of electricity, the flow rate of feed water, or the integrated value of electrolysis time itself does not represent the amount of deposition due to the precipitation of calcium. Therefore, the exact amount of deposition cannot be detected, and the effective amount of calcium component that is actually suitable is not detected. There is a problem that it cannot be removed easily.

Further, at the time when it seems that calcium components are deposited and laminated to some extent, a calcium removing agent supply cartridge is manually set in place of the water purification cartridge constituting the water purification section, and water is passed to pass the calcium component in the pipe. It is conceivable to remove the adhered substances of the above, but this is not only troublesome because it is necessary to manually set the calcium removal agent supply cartridge instead of the water purification cartridge, and it is also effective to remove calcium. In some cases, the calcium removing agent supply cartridge may be set and flown even though the amount of stacking due to the precipitation of calcium components is small, and the calcium removing agent may be wasted.

The present invention has been made in view of the above-mentioned problems of the conventional examples, and its purpose is to prevent the pipes from being clogged or the capacity of the electrolytic cell to be deteriorated due to deposition due to precipitation of calcium components. (EN) It is intended to provide an ionized water producing device with a calcium component removing function, which can automatically and efficiently prevent it from occurring.
