Title:
浴水清浄化装置
Document Type and Number:
Japanese Patent JP4094691
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To heat stored water up to a prescribed temperature accurately, by calculating heat quantity required for warming stored bath water to a prescribed temperature, radiation heat quantity, and heat quantity required for heating low temperature bath water up to a prescribed temperature and operating a heating means by midnight power for heating time corresponding to the heat quantity summed up. SOLUTION: A first calculation device 51 calculates heat quantities A and B to heat bath water and hot water in a heat accumulating tank 13 up to respective prescribed temperature. Then, a second calculation device 52 calculates radiation heat quantity in the midnight power time zone based on a detected outside temperature. A control device 6 instructs a third calculation device 53 to calculate a heat quantity C to heat water up to an storing temperature when the circulating bath water temperature detected by a water inlet side temperature sensor 20 is judged lower than a prescribed temperature. From calculated heat quantities A, B, and C and the radiation heat quantity, a heating time calculation device 50 calculates a heating time T required for a heat accumulation heater 18 and performs heating at a heat accumulation tank 13 for the calculated time. Thus, highly accurate heating without lack of heating can be realized.
