HOT-WATER SUPPLY CONTROL METHOD FOR BATHTUB WITH ONE- CAN AND TWO-CIRCUIT TYPE WATER HEATER, AND BATHTUB WITH ONE-CAN AND TWO-CIRCUIT TYPE WATER HEATER FOR CARRYING OUT THE SAME

摘要

PROBLEM TO BE SOLVED: To provide the hot-water supply control which can automatically supplying a set temperature and a set quantity of hot-water into a bathtub even in the case of combustion at the set temperature as a target temperature when unexpected additional heating is done by supplying hot-water to the bathtub with a double-carrying method in a reheating circulation circuit for supplying hot-water with a one-can and two-circuit type method. SOLUTION: After supplying hot-water at a set temperature by the initial set supply quantity Qh1 that a circulation adapter 201 is submerged, hot-water supply is stopped. A circulation pump is operated to detect a real bath temperature (a real temperature raised than the set bath temperature by additional heating) with a bath temperature sensor provided on a reheating circulation circuit. On the basis of the real bath temperature, additional hot-water supply quantity Qh2 and additional water supply quantity Qc to be required to raise the whole of the set hot-water quantity Qs to the set bath temperature are computed. The obtained additional quantity of the hot-water and the obtained additional quantity of water are supplied. A circulation pump agitates inside of a bathtub 200 to even temperature of the hot-water in the bathtub. COPYRIGHT: (C)2004,JPO
