Title: Hot water supplying mechanism for instantaneous water heater
Inventor: NISHI TAKAHIRO
IPC: F24H1/10
Filed: 1989-12-30
Abstract: PURPOSE:To obtain hot water of suitable temperature at a small flow rate even if the temperature of the water is high by providing operation means for moving a valve body by a heat responsive element provided in a confluent passage to vary flow rate ratio of water passage to hot water passage in a mixing valve to bias the element, and operating the mechanism corresponding to the set temperature of an output hot water temperature setter. CONSTITUTION:Hot water heated by a heat exchanger 3 by burning of a burner 12 and fed through a hot water passage 1 is mixed with clean water fed through a water passage 5 in a mixing valve 4 to lower at its temperature, fed through a confluent passage, and output from a hot water supply outlet 18. In this case, since a heat responsive element 7 moves a valve body 8 in response to hot water temperature in the confluent passage, the flow rate ratio of the passage 5 to the passage 1 is varied, and the hot water in the confluent passage can be regulated to a value responsive to the biasing amount of the element 7. The biasing amount is varied by operation means 9 corresponding to the set temperature of an output hot water temperature setter 14, and hot water temperature can be regulated by the setter. Thus, since the hot water heated by the exchanger 3 is cooled with clean water and output from the outlet 19, hot water of low temperature can be supplied even if the minimum burning amount of the burner 12 is relatively large.
