Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrolytic ion water generator for electrolyzing water to separate it into alkaline ion water and acidic ion water.

[0002]

2. Description of the Related Art An electrolytic cell used in an electrolytic ionized water generator which is generally used at present is of a so-called diaphragm type in which a diaphragm is arranged between an anode plate and a cathode plate to which a DC voltage is applied. It is roughly classified into two types of non-diaphragm type disclosed in, for example, Kaihei 6-246272.

On the other hand, the diaphragm type electrolytic cell has an advantage that alkali ion water and acidic ion water are not mixed by the diaphragm and high pH performance is obtained, but bacteria and microorganisms such as mold are generated in the diaphragm part. In addition, since the diaphragm is arranged between the electrodes, there is a problem that the distance between the electrodes is large, power consumption tends to increase, and the laminated arrangement of the electrodes and the diaphragm complicates the structure.

On the other hand, the non-diaphragm type electrolytic cell is characterized in that it does not generate bacteria or microorganisms because it does not have a diaphragm, and that it can reduce the distance between the electrodes, thus reducing power consumption. There is a problem that the ionic water and the acidic ionic water are easily mixed due to turbulence of the water flow and the pH accuracy is not stable.

Therefore, in the above diaphragmless electrolytic cell, high p
When pursuing the reason why H performance is not obtained, the amount of acidic water generated on the surface of the anode plate is approximately proportional to the current density applied to the electrode plate. As a result, the acidic water layer is very thin near the inlet of the electrolysis chamber, but becomes thicker toward the downstream of the electrolysis chamber, and has a certain thickness near the acid water recovery port. But the boundary with non-electrolyzed water becomes blurred.

However, in the electrolytic cell disclosed in the above publication, etc., the opening for recovering the acidic water is opened in a direction substantially at right angles to the anode, so that it is difficult to recover the acidic water in a portion slightly away from the anode. There's a problem.

[0007]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to efficiently recover the acidic water produced on the surface of the anode plate with a relatively simple structure.

[0008]

According to the present invention, a pair of electrode plates are arranged facing each other with a gap acting as an electrolysis chamber, and tap water or the like is continuously passed through the gap. In a case where a voltage is applied between the plates to perform electrolysis, a first generated water recovery passage is provided near one of the water passage downstream ends of the electrode plate, and the first generated water recovery passage and one of the electrode plates are connected. The second produced water recovery port is provided between the upstream end of the water passage.

Further, according to the present invention, a pair of second electrode plates are arranged on both sides of the first electrode plate so as to face each other with a gap acting as an electrolysis chamber, and tap water or the like is continuously provided in the gap. In a device for electrolyzing by applying a voltage between the first and second electrode plates while passing water through the first electrode, a first generated water recovery passage is provided near the water flow downstream end of the electrode plate, and A second produced water recovery port is provided between the produced water recovery passage and the water passage upstream end of the second electrode plate.
