Abstract

PURPOSE: To prevent the title device from corrosion by maintaining water in good quality and condition, by detecting hydrogen ion concentration of a liquid being heated and draining the liquid as required.
CONSTITUTION: In a liquid storing section 6 of a main body 1 of a liquid heating device, a detector 4 which issues signals by oxygen ion concentrations is arranged in such a manner that it always contacts a liquid being heated, and at the same time, an electromagnetic valve 6 which is opened and closed through a control circuit 15 by the signals of a draining pipe 5 and the detector 4 is provided on the bottom of the liquid storing section 6. When the quality of water in the storing section 6 is in a condition of pH>7, the valve 16 is opened by the signal of the detector 4, and the liquid in the storing section 6 is drained out from the draining pipe 5. This operation is continued until the water is in a condition of pH=7, so that the storing section 6, a circulating equipment 10 and a circulating system can be prevented from corrosion, and at the same time, the water can be maintained in a good quality and condition without imparting stimulus to a human body.
