Field of the Invention The present invention relates to an electrolyzed water generating apparatus, and more particularly, to an electrolyzed water generating apparatus, in which the inside of the apparatus is divided into an anode chamber containing a plus electrode and a cathode chamber containing a minus electrode. supplying raw water to the electrolytic cell which is partitioned by electrolytic treatment in the anode chamber and the cathode chamber, so alkaline ionized water from an outlet of the cathode chamber with acidic ionized water is obtained from the outlet of the anode chamber is obtained The present invention relates to a configured electrolyzed water generator. [0002] In this type of electrolyzed water generating apparatus, tap water or groundwater is used as raw water supplied to an electrolytic cell for the purpose of reducing the production cost of each electrolyzed ionic water. As shown in JP-A-5-115875, a filter for removing residual chlorine in tap water may be provided on the inflow side of the electrolytic cell. In some cases, a filter for removing relatively large foreign matter such as dust is provided instead of or in addition to the filter. [0003] In the above-mentioned conventional electrolyzed water generating apparatus, it is impossible to remove contaminants such as organic substances and fine colloid particles mixed in raw water. By the way, when raw water containing contaminants such as organic substances and fine colloid particles is supplied to an electrolysis tank and subjected to electrolytic treatment, the contaminants are involved in an oxidation reaction particularly occurring on the surface of the positive electrode, and the electrolysis products (raw water is supplied by tap water). In the case of only water or groundwater, O 3 , OH radicals, oxygen ions, etc. are generated,
If the raw water is tap water or dilute saline obtained by adding salt to groundwater, hypochlorous acid is also generated in addition to the above-mentioned product), and the above contaminants may not only be reduced. The decomposition of the electrolysis products in each electrolyzed ionic water may be accelerated, and the storage stability of each electrolyzed ionic water may be reduced. The present invention has been made to address the above-described problem, and an object of the present invention is to remove contaminants such as organic substances and fine colloid particles from raw water supplied to an electrolytic cell. [0004] Means for Solving the Problems The present invention has been partitioned into a cathode compartment housing the anode chamber and the negative electrode accommodating the positive electrode and the interior by the eye, septum membrane to achieve the above object Salt was added to raw water such as tap water or groundwater in the electrolytic cell
Brine and supplies to electrolytic treatment in the anode chamber and a cathode chamber, before
Before with acidic ionized water is obtained from the outlet of the serial anode chamber
In an electrolyzed water generator configured so that alkaline ionized water can be obtained from the outlet of the cathode chamber , the electrolytic water is supplied to the anode chamber.

Includes a water level sensor 11 (for detecting an upper limit water level and a lower limit water level) and a salt concentration sensor 12 which are connected to a control device 30. The signals from the water level sensor 11 and the salt concentration sensor 12 serve as water supply sensors. An electromagnetic on-off valve V1 provided on a water (sometimes groundwater) supply pipe 13 is opened and closed, and a pinch valve V2 provided on a concentrated salt water supply pipe 15 connected to a concentrated salt water (saturated saline) storage tank 14 is provided. Is opened and closed so that the level and concentration of the dilute salt water in the storage tank 10 are maintained in predetermined ranges, respectively. [0007] The storage tank 10 has a connection pipe 1 branched and connected to both inlets 21a and 21b of the electrolytic cell 20.
A constant flow type electric pump P1 whose operation is controlled by the control device 30 and a flow sensor 17 connected to the control device 30 are interposed in the connection pipe 16, respectively. And purification filter 19
The dilute salt water in the storage tank 10 is passed through the connection pipe 16 and purified by the threading filter 18 and the purification filter 19 by driving the electric pump P1.
The two flow inlets 21a and 21b are connected to each other so that the flow rate flowing through the connection pipe 16 is detected by the flow rate sensor 17. The flow rate sensor 17 is provided to check the purifying function of the purifying filter 19, and when the flow rate sensor 17 does not detect a predetermined flow rate even though the electric pump P1 is driven (flow rate). In the case of an abnormal decrease and an abnormal increase in the flow rate), the alarm means (not shown) is activated assuming that the purification function of the purification filter 19 is abnormal. The thread filter 18 removes relatively large solids, and the purification filter 19 has an ultrafiltration membrane, and allows water and ions and molecules similar to these to pass therethrough, but it does not contain colloids or other substances. Block permeation and remove from raw water. The electrolytic cell 20 includes a pair of inlets 21a, 21
