Embodiment 2
[0036] Embodiment 2, an energy-saving control method for an electric water heater
[0037] The main difference between the second embodiment and the first embodiment is that the control method in the second embodiment also has a heat preservation state after entering the standby mode. When the electric water heater enters the heat preservation state, the control device continuously monitors the water temperature in the inner tank, and judges whether the water temperature in the inner tank is lower than the set heat preservation temperature T1, and T1 is lower than the heating temperature T0. If the water temperature in the inner tank is lower than the heat preservation temperature T1, the heating unit works to heat the water in the inner tank to the set temperature T2. T1=T0-N1, T2=T0-N2, N2 is smaller than N1, so that the liner can be kept near the heat preservation temperature.

The invention discloses an energy-saving control method for an electric water heater. The method comprises the following steps that S1, an on-off key is pressed, the electric water heater enters a power-on mode, and a heating unit heats water in an inner container; S2, the temperature of the inner container is judged, whether the temperature of the water in the inner container reaches a set heating temperature T0 or not is judged, and if the temperature of the water in the inner container reaches T0, the step S3 is executed, and when the temperature of the inner container does not reach T0, the heating unit continues to heat the water in the inner container; S3, the heating unit stops heating; S4, time judgment is conducted, whether water is used within the time T0 after the heating unit stops heating or not is determined according to the water temperature change in the inner container, if no water is used within the time T0, the step S3 is executed, and if the water is used, the stepS2 is executed; and S5, a standby mode is started. According to the method, control is convenient, after the water in the inner container is heated to the set temperature, if no water is used for a period of time, a standby state can be automatically switched, and therefore the purpose of saving energy is achieved.
Description
technical field [0001] The invention relates to an electric water heater control method, in particular to an electric water heater energy-saving control method. Background technique [0002] At present most electric water heaters all adopt volumetric type. Before taking a bath, the water stored in the inner container needs to be heated earlier to make it have a higher temperature, and then the heated water is mixed with cold water for bathing. Most of the existing water heaters have a switch function. When using the electric water heater for the first time, first turn on the power switch, and the electric water heater is in a continuous heating state. The water heater enters the keep warm state. When the electric water heater is in the heat preservation state, the water temperature in the inner tank is lower than the set heating temperature, and the electric heating rod will be energized again to heat the water temperature in the inner tank to the set heating temperature. ...
