  • the second end of the water discharge bypass 20 is connected to the drain 18.
  • the water discharge bypass 20 has a pH sensor unit 22.
  • the pH sensor unit 22 is configured to measure the hydrogen ion index of the liquid flowing through the water discharge bypass 20.
  • the senor in the embodiment is not limited to the pH sensor unit 22. That is, the sensor is not limited to the sensor that measures the hydrogen ion index of the liquid flowing through the water discharge bypass 20. In other words, the sensor only needs to measure information indicating the hydrogen ion index of the liquid flowing through the water discharge bypass 20. In other words, the sensor may be configured to measure information corresponding to the hydrogen ion index of the liquid flowing through the water discharge bypass 20.
  • the drainage channel 18 further includes a drainage channel throttle 19.
  • the second end of the drainage channel 18 is defined by a drainage port.
  • the second end of the water discharge bypass 20 is connected to the drain 18 so as to be positioned between the drain 19 and the drain.
  • the water discharge bypass 20 has a water discharge bypass throttle 21.
  • the electrolyzed water generating device further includes a flow rate detection unit 6.
  • the flow rate detection unit 6 is configured to detect the flow rate of the liquid flowing into the electrolytic cell 12.
  • the anode chamber is configured to receive water through the introduction path.
  • the introduction path has an anode chamber throttle.
  • the anode chamber is configured to receive the liquid via the anode chamber introduction path.
  • the cathode chamber is configured to receive liquid via the cathode chamber introduction path.
  • the anode chamber introduction path is arranged independently of the cathode chamber introduction path.
  • the anode chamber introduction passage has an anode chamber throttle.
  • the electrolyzed water generating device has an introduction path.
  • the introduction path has an introduction path for the anode chamber and an introduction path for the cathode chamber.
  • the anode chamber is set so that the internal pressure is higher than that of the cathode chamber.

Abstract

Cette invention utilise une partie fusionnement pour fusionner une partie de l'eau ionisée acide générée par une anode dans un bain électrolytique, avec l'eau ionisée alcaline générée par une cathode. Ce dispositif générateur d'eau électrolysée permet d'augmenter la quantité d'hydrogène dissous sans que la valeur de pH de l'eau ionisée alcaline utilisée pour la consommation ne s'élève trop.
