Title: Controlling method of hot water supply of hot-cold water combination type tap-controlled water heater
Inventor: YAMAMOTO TAKANORI
IPC: F24H1/10
Filed: 1990-10-12
Abstract: PURPOSE:To prevent boiling of hot water and lowering of temperature due to a delay in response by controlling a heating means in a prescribed temperature range of a high temperature region when a necessary capacity of the heating means is lower than a first set capacity, while controlling it at a temperature of hot water calculated back to a second set capacity being still lower than the first one, when the necessary capacity thereof does not meet the second set capacity. CONSTITUTION:A control means 13 leads out a necessary capacity of a heating means 12, and when the necessary capacity is lower than a first set capacity in a low capacity region, it subjects the heating means 12 to an ON-OFF control in a prescribed temperature range of a high temperature region so as to prevent boiling of water in a heat exchanger 3. In the case when the necessary capacity led out does not meet a second set capacity being still lower than the first set capacity, on the occasion, a temperature of hot water calculated back to the second set temperature is taken as a set temperature of hot water and the ON- OFF control is executed. Thereby the operation in the second set capacity of the heating means 12 is maintained, the boiling of hot water in the heat exchanger 3 in the process of the ON-OFF control is prevented and the lowering of the temperature of hot water can be prevented, although it becomes higher a little than a temperature set initially.
