Title:
HOT WATER INJECTION DEVICE AND HOT WATER INJECTION METHOD
Document Type and Number:
Japanese Patent JP3532716
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a hot water injection device which can be manufactured at low cost in simple structure so as to inject hot water at a specified temperature and a hot water injection method as well.
SOLUTION: A hot water injection device is provided with a heating device 2 which heats up and raises the temperature of supply water substantially with a definite amount of heating per unit time. A thermistor 23, which detects an injection water temperature, is provided o the downstream side of the heating device 2. The heating device 2 is on/off controlled based on the ratio determined by a differential temperature between an injection water temperature T1 detected before the operation of the heating device 2 and a setting injection water temperature Tset and a differential temperature between an injection water temperature T2 which has reached the upper limit by operating the heating device 2 in continuous mode and the setting injection water temperature Tset.
