Water treating device

A water treating device comprising:

• a water container for containing water to be treated;
• an electrolyzing chamber for causing electrochemical decomposition by energization of an electrode set consisting of at least two electrode plates;
• a feed line for filling the electrolyzing chamber with an electrolytic solution containing chlorine ions and having a function of promoting the electrochemical decomposition and, in this state, producing a sterilizing liquid having a sterilizing capability by way of electrolysis of the electrolytic solution by the energization of the electrode set, and supplying the produced sterilizing liquid into the water container;
• a residual chlorine sensor for measuring a residual chlorine concentration of the to-be-treated water;
• and
• introduction amount controlling means for controlling an amount of the sterilizing liquid to be introduced into the water container on the basis of the residual chlorine concentration of the to-be-treated water measured by the residual chlorine sensor;
• wherein a bypass line is provided which is connected to the water container for introducing the to-be-treated water into the residual chlorine sensor from the water container for the measurement of the residual chlorine concentration of the to-be-treated water, and feeding the introduced to-be-treated water back into the water container after the measurement.

• water level detecting means for detecting a water level in the electrolyzing chamber;
• and
• water level controlling means for controlling an amount of the sterilizing liquid to be introduced into the electrolyzing chamber on the basis of water level data from the water level detecting means to keep the water level in the electrolyzing chamber at a predetermined level;
• wherein the water level detecting means has at least two electrodes disposed in spaced opposed relation and is adapted to detect the water level on the basis of whether an electric current flows between the electrodes.
