Control system of electric water heater

Abstract

The invention provides an electric water heater control system. The electric water heater control system comprises the following steps of S1, acquiring the current temperature of water in an inner container of an electric water heater and a system clock of the electric water heater when detecting the ECO function mode of the electric water heater; S2, calculating the starting heating time corresponding to the heating and temperature rising rate according to the current temperature, the target temperature, the set water using time, the heating and temperature rising rate, the starting time of the peak valley power valley stage, the end time of the peak valley power valley stage; S3, dividing 24 hours into four time periods according to the starting time of the peak valley power valley stage, the end time of the peak valley power valley stage, the heating starting time corresponding to the heating and temperature rising rate and the set using time; and S4, judging the corresponding time period of the system clock, and conducting corresponding control over the electric water heater according to the judgment result. The electric water heater control system can meet the requirements of users for hot water well, effectively avoid the power peak period and save energy and electricity.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a heating control method and control system for an electric water heater. Background technique [0002] At present, electric water heaters have become a fairly popular household appliance. With the existing electric water heaters, when users need hot water, they need to wait for the water temperature to reach the required temperature or need to adjust the temperature frequently, which is very inconvenient. People sometimes keep the water heater in the power-on state all the time, and keep warm after the temperature is heated to the required temperature. Users can use hot water at any time, but it causes a very large waste of electric energy, especially now that our country implements peak and valley electricity. Although some manufacturers have configured an appointment function on electric water heaters, the operation of the appointment function is complicated, an...
