Water temperature control method and device

Abstract

The invention discloses a water temperature control method and device. A water inlet valve on a water inlet pipe is turned on; a water pump is operated, and water currents are heated by a heat exchanger to reach a temperature detecting point; the water temperature of the temperature detecting point is a water outlet temperature; the water outlet temperature is compared with a first set temperatureand a second set temperature; when the water outlet temperature is lower than the first set temperature or higher than the second set temperature, the water inlet valve is turned off, a water returnvalve is turned on, and the water currents are continuously circulated among the water pump, the water inlet valve, the heat exchanger and the water return valve until the water outlet temperature ishigher than the first set temperature and lower than the second set temperature; the water return valve is turned off, the water inlet valve is turned on, and the water currents flow out from a wateroutlet pipe; and when the water outlet temperature is higher than the first set temperature and lower than the second set temperature, the water currents are discharged from the water outlet pipe. Thewater outlet temperature can be effectively controlled to prevent the problem of hot and cold feelings.

Description

technical field [0001] The invention relates to a water temperature control method and device. Background technique [0002] During the use of fast household central hot water gas water heater, the gas water heater stops burning and does not work when the gas water heater runs out of hot water. In the case of overheating and short-term hot water, when the water heater is turned on again, it will take a period of time for the water heater to reach the corresponding temperature from ignition to combustion. It is very inconvenient to use, and it is difficult to grasp the outlet water temperature. Contents of the invention [0003] The technical problem to be solved by the present invention is: a water temperature control method is needed, which can better control the outlet water temperature. [0004] The solution of the present invention to solve its technical problem is: a water temperature control method, open the water inlet valve on the water inlet pipe, the water pump...
