Description of the Related Art An electrolyzed water generator is connected to a water supply facility such as a water supply, and performs electrolysis in a flowing water state to generate acidic water or alkaline water. There is a batch method in which water is electrolyzed in a stagnant state. The flowing water method has the merit that electrolyzed water can be taken immediately. However, when an acidic water with strong oxidizing power (hereinafter referred to as strong acid water) or an alkaline water with strong reducing power (hereinafter referred to as strong alkaline water) is obtained.

い。Further, since the electrolyte solution is supplied only to the anode chamber, alkaline water having a strong reducing power can be obtained in a short time. That is, when a voltage is applied between the positive electrode and the negative electrode, the ions contained in the water to be electrolyzed move by passing through the diaphragm due to the electric attraction force. Therefore, the Na ions of the salt introduced into the anode compartment immediately move to the cathode compartment through the diaphragm. In addition to the electric attractive force, for example, according to the diffusion theory, Na ions act to make the ion concentration uniform by diffusion. As a result, the current flowing between the positive electrode and the negative electrode increases, and alkaline water having a strong reducing power can be obtained in a short time. This strong alkaline water has a saponifying or emulsifying action on fats and oils and a hydrolyzing action on proteins, and can be used as washing water for furniture, housing building material surfaces and the like. Since the cathode chamber is raw water, the amount of ions transferred to the anode chamber is extremely small.

The abundance ratio of lO has a pH dependence, and the abundance ratio of chlorine gas Cl 2大 き く increases and the abundance ratio of hypochlorous acid decreases as the acidity increases. For example, when the pH becomes 2 or less, the abundance ratio of chlorine gas exceeds about 30%. When the pH is 4 or more, the chlorine gas abundance becomes several percent, and the chlorine gas odor becomes a level that is hardly noticeable. On the other hand, hypochlorite ion ClO exceeds pH7 is neutral - abundance ratio abruptly increases and sterilizing power of is decreased. Therefore, in the case where the pH is set in the range of 4 to 7 and sterilized water is used while preventing the adverse effect of chlorine gas, sterilized water having a high content of HClO hypochlorite can be obtained.

Raw water in the anode chamber 13 is sent to the salt tank 23 via the introduction path 28. The salt tank 23 is formed in a watertight state, and when the raw water is introduced, the supersaturated salt solution is stored in the anode chamber 13 from the salt supply port 30 through the electrolyte bed 25, the salt supply passage 29, and the check valve 31. It is supplied in a fixed amount and becomes a salt dilution water having a predetermined concentration. Next, the control circuit 42 operates to reverse the polarity between the anode 15 and the cathode 16, that is, the anode 15 side has a negative polarity,
A current is applied for a predetermined time tr with the cathode 16 side being a positive pole. Thus, the scale component deposited on the surface of the cathode 16 by the previous electrolysis is oxidized and reduced and washed. In other words, raw water contains various ions, and particularly cations such as calcium ions and magnesium ions react with hydroxyl groups on the cathode chamber 14 side to form calcium hydroxide and magnesium hydroxide. Deposits on the surface of the diaphragm 16 and the diaphragm 12 and become an obstructive factor of the electrolytic current. However, by performing the reverse-current cleaning for a predetermined time tr before the electrolysis, the cleaning is performed well and the scale components are decomposed, thereby extending the life of the electrode. it can.

When a voltage is applied between the anode 15 and the cathode 16, the ions contained in the water to be electrolyzed become positive / negative by the electric attraction force.
The ions having the opposite polarity move through the diaphragm 12. Therefore, Na ions contained in the salt introduced into the anode chamber 13 immediately move to the cathode chamber 14 via the diaphragm 12. In addition to the electric attractive force, for example, according to the diffusion theory, Na ions act to make the ion concentration uniform by diffusion. As a result, the current flowing between the positive / negative electrodes 15 and 16 increases, and alkaline water having a strong reducing power can be obtained in a short time. The alkaline water having a strong reducing power has a saponifying or emulsifying effect on fats and oils and a hydrolyzing effect on proteins, and can be used as washing water for surfaces of furniture, housing materials, electric appliances and the like.

Cathode water is refluxed. Cathode water is in the anode chamber 13
The acidic water is neutralized so that the pH is in the range of 4 to 7 by being mixed into the water. Here, acidic water has a bactericidal action,
This bactericidal action is mainly obtained by HClO hypochlorite. The abundance ratio of this hypochlorite HClO has a pH dependency as shown in FIG.
The abundance ratio of 2 % increases, and the abundance ratio of hypochlorous acid decreases. For example, when the pH becomes 2 or less, the abundance ratio of chlorine gas exceeds about 30%. When the pH becomes 4 or more, the abundance ratio of chlorine gas becomes 2% or less, and the chlorine gas odor becomes a level which is hardly noticeable. On the other hand, hypochlorite ion ClO exceeds pH7 is neutral - abundance ratio abruptly increases and sterilizing power of is decreased. Therefore, when the pH is set in the range of 4 to 7, when using as sterilizing water while preventing the adverse effect of chlorine gas, sterilizing water having a high content of HClO hypochlorite can be obtained. According to the experiment, the anode chamber 13 and the cathode chamber 14 were each filled with 800 CC of water by 400 CC, and electrolysis was performed at 1 A for 5 minutes to generate strong alkaline water having a pH of 12.1 on the cathode chamber side. A strongly acidic water of pH 2.6 was obtained. After the electrolysis, the discharge means 32 was driven to reflux about 30% of the strong alkaline water into the anode chamber, whereby the pH of the anode water became 4.5. The anode water is discharged through the drain passage 38 by opening the drain valve 39. The anode water is filled in a container such as a spray bottle (not shown) in the same manner as the cathode water, and if used as sterilizing water, as shown in FIG.
Sterilized water having a high ClO abundance can be obtained.

In other words, when the salt supply port 30 is provided below the liquid level of the salt tank 23, the electrolyte solution always flows out into the anode chamber 13 due to the head difference, and the electrolyte concentration during electrolysis cannot be maintained at a predetermined value.

As a result, an electrolyte solution having a desired concentration is always supplied to the electrolytic cell from the salt supply port 30 with high accuracy, and a stable pH value is obtained.

In other words, by performing electrolysis, calcium and magnesium ions contained in the raw water react with hydroxyl groups to form scales such as calcium hydroxide and magnesium hydroxide and adhere to the cathode 16 and the cathode chamber 14 wall surface. There is a case where minute scale pieces are mixed in the raw water due to the peeling action at the time of putting. Therefore, the cathode chamber 1
