Abstract

The invention relates to a water heater control system with a zero cold water function and a working method. The system comprises a controller, a circulating pump and a water flow sensor. The controller comprises a single-chip microcomputer, a display unit and a key unit. The water flow sensor is used for detecting the flow velocity of water flow passing through a water flow circulation loop. Thesingle-chip microcomputer comprises a timing unit and a water quantity calculation unit, the timing unit is used for monitoring the time when water flow continuously passes through the water flow sensor at a time, and the water quantity calculation unit is used for obtaining data transmitted by the timing unit and the water flow sensor and conducting calculating to obtain the real-time water quantity Q1. The display unit is used for displaying the real-time water quantity Q1 and the set water quantity Q0, and the set water quantity Q0 is the volume of a hot water pipe. When the single-chip microcomputer receives a key instruction of a zero cold water key to enable the zero cold water function, the circulating pump is started, if water flow exists in the circulating loop, the real-time water quantity Q1 is heated to reach the set water quantity Q0, then a hot water use prompt is sent out through the display unit or a sound unit, and then the circulating pump is turned off.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a water heater control system and working method 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...
