The invention relates to a working method of a water heater with zero cold water function, comprising a water heater control system with zero cold water function, the system includes a controller, a circulating pump and a water flow sensor; the controller includes a single chip microcomputer, a display unit and a key unit; The flow sensor is used to detect the flow rate of the water flow through the water circulation circuit; the single-chip microcomputer includes a timing unit and a water flow calculation unit. The timing unit monitors the time for the water flow to pass through the water flow sensor continuously for a single time, and the water flow calculation unit obtains the data transmitted by the timing unit and the water flow sensor. And calculate the real-time water quantity Q 1 ;The display unit displays the real-time water volume Q 1 and set water quantity Q 0 , the set water quantity Q 0 is the volume of the hot water pipe; the single-chip microcomputer receives the key command of the zero cold water key to enable the zero cold water function, start the circulation pump, and heat the real-time water volume Q when there is water flow in the circulation loop 1 Reach the set water volume Q 0 Finally, the hot water usage reminder is issued through the display unit or the sound unit, and then the circulation pump is turned off.
Description
technical field [0001] The invention relates to the technical field of water heaters, in particular to a working method of a water heater with zero cold water function. Background technique [0002] The user generally has a certain distance between the water point and the gas water heater. When using hot water, the user needs to drain the cold water in the hot water pipe first, and wait for the hot water heated by the gas water heater to flow before using it, which causes a part of water waste. [0003] The zero-cold water function of existing gas water heaters with circulation pumps generally heats the cold water pipes with hot water, so that when the user starts to use water, the cold water pipes at the water point need to be drained of the hot water before using cold water, which wastes gas , Such products on the market generally consume a lot of energy and wait for the zero cold water function to complete the preheating time is relatively long, resulting in poor user exp...
