DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for continuously electrolyzing supplied tap water or the like in an electrolytic cell having a positive electrode and a negative electrode provided through an ion exchange membrane, to obtain alkaline ionized water and water. The present invention relates to an electrolytic ionic water generator that generates acidic ionic water.

2. Description of the Related Art In general, supplied tap water or the like is continuously electrolyzed in an electrolytic cell having a positive electrode and a negative electrode provided through an ion exchange membrane, so that alkali ion water and acidic ion water are converted. 2. Description of the Related Art There is known an electrolytic ionized water generator for producing the same. By the way, in order to drink alkaline ionized water, it is necessary to make the alkalinity appropriate. For this reason, conventionally, the electrolysis voltage applied to the positive electrode and the negative electrode is manually changed, thereby changing the alkalinity of the alkaline ionized water. For example, the electrolysis voltage was varied and set so that the alkalinity was appropriate while watching the results.

[0003]

The alkalinity as described above varies depending on the supplied tap water, mainly the water pressure, the amount of water (per hour), the temperature and the electric conductivity. Setting the electrolysis voltage does not always make the alkalinity constant. Therefore, it is conceivable to convert the alkalinity of the alkaline ionized water into an electric signal such as a pH meter so as to keep the alkalinity constant, and to automatically control the electrolysis voltage by the electric signal. However, those that convert the alkalinity into an electric signal, such as the pH meter, have a large change with time,
For this reason, frequent calibration is required, so that it is not practical to mount it on an electrolytic ionized water generator used for a long time.
The present invention eliminates the above-mentioned disadvantages of the related art, does not require the above-described calibration, and has an automatic alkalinity automatically even when the water pressure, the amount of water, the temperature, and the electrical conductivity of supplied tap water are changed. It is an object of the present invention to provide an electrolytic ionic water generation device which is made constant.

Means for varying the water pressure of the supplied tap water, the amount of water, the temperature and the electrical conductivity even if the electrical conductivity changes, or the acidity of the acidic ionic water is substantially constant. This is a feature of the present invention. The means for varying the electrolytic voltage may be constituted by a switching power supply.

Further, in the above-described embodiment, the description has been given of the case where the alkalinity of the alkaline ionized water is kept constant. However, the present invention can be applied to a case where the acidity of the acidic ionized water is kept constant. In the above embodiment, the detected values of the supplied water pressure, such as tap water, the amount of water, the temperature, and the electrical conductivity are input to the fuzzy chip 2 as fuzzy variables.
