Problems solved by technology
[0003] The applicant found that in the prior art, when the instant water heater starts to work, it takes a certain amount of time to start the heating element, and at the same time, the heat exchange between the heating element and the cold water cannot be completed in an instant, although the starting time of the heating element is relatively short. Short, but during this period of time, cold water has already flowed through the heating element and then flowed out of the water heater. Therefore, in the short period of time when the instant water heater is just turned on, some cold water that has not been fully heated will flow out. There will be heated hot water flowing out

The application provides a constant temperature method for water output from a water heater, which is applied to an instant water heater. A first flow path and a second flow path are arranged in the water outlet passage of the water heater, and an independent storable water body is arranged in the first flow path. For the warm water tank that heats the water body, the first temperature of the water outlet from the water heater is detected; the second temperature of the water outlet from the water heater is detected after a first preset time; it is determined whether the absolute value of the difference between the first temperature and the second temperature is is greater than the first preset threshold to obtain a first judgment result; when the first judgment result is yes, switch the water outlet channel to the first flow path, and close the second flow path, so that the The water from the water heater flows out through the warm water tank. The cold water in the effluent water of the instant water heater can be prevented from directly flowing out, and the user experience can be improved. The present application also provides a constant temperature device for water outlet of a water heater.
Description
technical field [0001] The present application relates to the field of water heaters, in particular, to a method and device for constant temperature of outlet water from a water heater. Background technique [0002] The instant water heater can heat water in a short period of time through gas or electric energy. After the water outlet of the water heater is turned on, the instant water heater starts to work, and the cold water flowing through the water heater is heated by gas or electric energy. The outlet water of the instant water heater The way is to flow the heated water directly through a water outlet. [0003] The applicant found that in the prior art, when the instant water heater starts to work, it takes a certain amount of time to start the heating element, and at the same time, the heat exchange between the heating element and the cold water cannot be completed in an instant, although the starting time of the heating element is relatively short. Short, but during ...
