The constant flow valve used in the conventional electrolytic ionized water generator has a primary pressure input to the valve and a secondary pressure difference output from the valve set in advance, but the pressure of the raw water is If the fluctuation is large, the pressure difference between the primary side and the secondary side deviates from a preset value and normal operation is not performed. Therefore, the present apparatus uses a pressure reducing valve whose operation is stable.

In the present apparatus, the pressure of the raw water is stabilized by providing the pressure reducing valve 15 so that the flow rate of the ionic water in the throttle valve 8 can be more easily adjusted.

The squeezing valves 8a and 8b are manually operated valves for adjusting the flow rate of acidic ionic water or alkaline ionic water output from the electrolytic cell 5.

Only acidic ionized water or alkali ionized water is allowed to flow.
Scale adheres. If a squeeze valve is provided on the pipe, scale will easily adhere to the part where the flow path is narrowed by the valve, which will cause resistance, resulting in an unbalanced output flow of acidic ionized water and alkaline ionized water. , Which causes a variation in pH.

However, as shown in FIG. 1, after the throttle valve 8 is connected to the electrolytic bath 5 and before the three-port valve 7a, the piping alternately flows with alkaline ionized water and acidic ionized water due to the polarity reversal. By providing the throttle valve 8 here, it is possible to prevent the scale from adhering to the narrowest part of the flow path, and to stabilize the discharge amount of the acidic ionized water and the alkaline ionized water.

It has become.

Specifically, when the dial 32 is turned to the right,
The throttle valve 8 goes deeper, the flow path becomes narrower, and the flow rate of the ionic water decreases. Conversely, when the dial 32 is turned to the left, the throttle valve 8 comes out to the front, so that the flow path widens and the flow rate increases. Thereby, the flow rates of the acidic ionized water and the alkaline ionized water can be maintained at the specified flow rates, and the flow rates of both the ionized waters are made equal to stabilize the pH.

Also, by incorporating the throttle valve 8 into the electrolytic cell holder 31 as described above, even if the scale is attached to the throttle valve 8, the dial 32 is turned to rotate the throttle valve 8.
