Title: Water heater
Inventor: ONISHI HIROYUKI
IPC: C02F1/46
Filed: 1990-03-12
Abstract: PURPOSE:To prevent propagation of various bacteria and to sanitarily store hot water by providing a controlling device capable of impressing voltage being continuously changed between a first electrode and a second electrode and sterilizing the hot water in the inside of a water heater. CONSTITUTION:When hot water is stored in the inside of a water heater 1 for a long time in a state wherein takeout of hot water from the outlet 2b of the water heater 1 is stopped, various bacteria such as colibacillus and Pseudomonas start propagation in the inside. In this case, voltage incorporating voltage intensive in sterilizing power for propagative various bacteria is impressed repeatedly in a sawtooth shape between a plus electrode 7 and a minus electrode 8. At this time, minimum impression voltage is set at about 0.7V and maximum impression voltage is set at about 1.5 V. Therefore various bacteria propagated in the hot water stagnated in a heat exchanger main body 2 are sterilized by repeatedly impressed voltage intensive in sterilizing power. Clean hot water can be maintained.
