The raw water tank 10 is a tank for storing the water (raw water) to be electrolyzed. The raw water may be used tap water, fresh water, sea water, ground water. The raw water tank 10 may not be necessary in the case where the multistage membrane-free electrolytic water generating device according to the present invention is directly connected to the tap water.

The pump 12 is a device for transferring the raw water of the raw water tank (10). The pump 12 is preferably a metering pump.

The raw water passing through the pump 12 passes through the filter 14. The filter 14 filters various ions or impurities contained in raw water. The raw water passing through the filter 14 flows into the mixing tank 30.

Even if the pump 12 is not a metering pump or a metering pump, a pressure reducing valve (not shown) is installed between the filter 14 and the mixing tank 30 in case the function of the metering pump is deteriorated. A bypass pipe (not shown) branched between the filter 14 and the decompression valve and directed toward the raw water tank 10 may be provided.

In the multistage membrane-free electrolytic water generating device according to the present invention, an additive liquid tank 20 is positioned separately from the raw water tank 10, and the additive liquid tank 20 includes an additive liquid, that is, sodium chloride solution, potassium chloride solution, and calcium chloride solution. Solutions that must be added to electrolyze water are stored.

The additive liquid tank 20 and the mixing tank 30 are connected by a pipe, and the additive liquid pump 22 is interposed therebetween. The pipe connected from the additive tank 20 to the mixing tank 30 is directly connected to a pipe connected from the filter 14 to the mixing tank 30 or is connected to an adjacent place of the raw water and the additive liquid. It is advantageous to mixing.

The additive liquid tank 20 and the additive liquid pump 22 may be omitted when electrolyzing the raw water without the additive liquid.

The pipe drawn out from the upper portion of the mixing tank 30 is drawn into the lower portion of the primary electrolytic bath 40. The primary electrolyzer 40 electrolyzes the introduced raw water, and the electrolyzed primary electrolyzed water is withdrawn to the upper portion of the primary electrolyzer 40.
