HOT WATER FEEDING DEVICE FOR BATH TUB AND DEVICE FOR KEEPING TEMPERATURE OF HOT WATER IN BATH TUB

摘要

PROBLEM TO BE SOLVED: To prevent hot water of high temperature from being fed into a bath tub when component elements such as a hot water/cold water mixing valve, a temperature sensor and a control device or the like in a device for feeding hot water in the bath tub and a device for keeping a temperature of hot water in the bath tub are troubled or kept at abnormal states. ;SOLUTION: An outlet port of a hot water/cold water mixing valve 12 is provided with a mechanical device 30a for preventing a temperature of hot water from being excessively increased. When this mechanical device 30a for preventing a temperature of hot water from being excessively increased is operated, its power supply circuit is forcedly shut off or turned off to cause a hot water feeding operation to be stopped. In addition, a mechanical device 30b for preventing a temperature of hot water from being excessively increased is arranged in a circulating circuit and also its power supply circuit is forcedly shut off or turned off when this mechanical device 30b for preventing a temperature of hot water from being excessively increased is operated, thereby its temperature keeping operation is stopped.;COPYRIGHT: (C)1998,JPO
