Document Type and Number:
Japanese Patent JP3078785
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To control the quantity of a water in a bathtub easily by dividing the product of heating time, quantity of heat applied from a heating means to the water and thermal efficiency by a specified temperature to determine the current quantity of the water in the bathtub and then comparing the current quantity of the water with a set level. SOLUTION: A detected quantity of the water is compared with a set quantity of the water to determine a deficient quantity of the water and a service water corresponding to the deficient quantity is detected by a water quantity sensor 47. It is then heated by a second heating means 28 and supplied from a circulation passage to a bathtub 20 thus sustaining the quantity of the water in a bathtub at a set level. Furthermore, a pump 56 is operated every predetermined time to circulate the hot water 4c in the bathtub through a circulation passage 60 while stirring. When the temperature of the hot water 4c detected by a temperature sensor 70 is lower than a set level, the hot water in the bathtub is heated up to the set level by a first heating means 24. Since the hot water in the bathtub can be controlled to the set temperature and the set quantity, a comfortable bath environment can be realized. The quantity of heating can be determined easily using a set gas pressure for thermal efficiency and a stabilized water quantity control can be realized.
