The electric water heater adopts electric energy as a main energy material, and the high-temperature heat generated after the electric energy is electrified directly heats water stored in the electric water heater so as to achieve the purpose of preparing hot water.
The electric water heater generally comprises a water tank, an electric heating component, an electric control board and the like, wherein a water storage cavity is formed in the water tank to store water to be heated, the electric heating component is inserted into the water storage cavity formed by the water tank, and the electric control board is used for controlling the electric heating component to be powered on and powered off so as to heat the water in the water tank to a set temperature.
For a water tank of an electric water heater, the water tank generally comprises a shell and an inner container, and an insulation layer is formed between the shell and the inner container. Wherein, the shell is generally made of plastic materials so as to meet the design requirements of beautiful and diversified shapes; the inner container can be a metal container body or a plastic container body according to the requirement.
In addition, the heat preservation that forms between shell and the inner bag, the heat preservation material that commonly uses has: asbestos, sponge, foam, polyurethane foam, etc., and in order to obtain a good heat-insulating effect in the conventional art, a heat-insulating layer is usually formed by foaming.
For the liner adopting the metal liner body, the inside of the liner is easy to corrode due to the influence of water quality, and therefore, the water tank is also provided with a magnesium rod which is inserted into a water storage cavity in the water tank.
Since magnesium is the lowest potential metal in the electrochemical sequence, it is physiologically non-toxic. Therefore, the magnesium rod protective liner is very ideal to be used for manufacturing the magnesium rod protective liner. The size of the magnesium rod is directly related to the time of protecting the liner and the protecting effect, and the larger the magnesium rod is, the better the protecting effect is and the longer the protecting time is.

For the electric heating component, electric heating modes such as electric heating wires, magnetic energy or silicon tube heating can be adopted to heat water stored in the water storage cavity.
For the electric control board, the electric control board is used for receiving detection signals sent by related sensors (such as a water temperature sensor and a flow sensor) and controlling the electric heating component to be powered on and powered off.
When the electric water heater works, the electric heating component is controlled by the electric control board to be electrified and heated, and when the water temperature of the water in the water tank reaches a set value, the electric heating component is controlled by the electric control board to be powered off.

The control method specifically comprises the following steps: learning mode and intelligent mode of operation.
In the learning mode, after water in the two inner containers is heated to a set temperature value T in every set period of N days, when the water temperature in the inner containers is reduced to a temperature greater than DeltaT in every minute, judging that the electric water heater is in a continuous water outlet state, and recording a water consumption starting time point T n of the same day; when the water temperature in the inner containers is lower than deltaT in every minute, the electric water heater is judged to be in a standby state, and meanwhile, the water heating quantity Q n required for heating the water temperature of the inner containers to a set temperature value is calculated according to the temperature difference of the water temperature of the two inner containers.
Specifically, in the actual use process of the electric water heater installed in the user's home, a period of time set by one week, two weeks, one month or the like may be used as the learning period. In each learning period, after the electric water heater is heated to the set temperature value T each time, judging whether a user uses a large amount of water or not by judging the descending speed of the water temperature in the inner container, and further judging and recording the water use starting time point T n of the user. After the water consumption of the user is finished, the water consumption Q n of the user using the hot water is calculated according to the water temperature drop amount in the liner, so that the heating amount of the electric heating component is controlled according to Q n.
Under the intelligent operation module, according to the water consumption starting time point t n obtained in the previous period, starting an electric heating component to heat water in the liner until the water temperature rises at the time point t calculated every day, wherein the heat generated by the electric heating component is not less than the water consumption Q n; wherein t=t n - Δt.
Specifically, during the use process of the water heater in the period, the automatic operation of the electric water heater is controlled according to the water use starting time point t n and the water use heat Q n obtained in the previous period. Under the condition of no hot water, the electric heating component can be not electrified to heat or can be in medium-low water temperature heat preservation operation at ordinary times, so that the temperature difference between the water in the inner container and the outside can be reduced, and the energy loss caused by heat conduction is further reduced, so that the energy-saving effect is achieved.
Meanwhile, in order to meet the requirement of users for using hot water normally, the electric water heater is started at a time point t calculated every day, so that the electric heating component is electrified to heat water in the inner container. And the heating quantity of the control inner container is heated by taking the water consumption quantity Q n calculated in the previous period as a reference. Therefore, on one hand, after the user returns home, the electric water heater can supply hot water in real time, so that the user does not need to wait for hot water heating, and on the other hand, the heating capacity of the electric water heater is controlled according to the water heat Q n of the previous period, so that the hot water use requirement of the user can be met, the heat waste caused by heating excessive hot water can be reduced, and further the energy consumption is effectively reduced.
In certain embodiments, under the intelligent operation module, the time point t is calculated from the minimum value t min in the water use start time point t n obtained in the previous cycle, i.e., t=t min —Δt.
Specifically, the time point t for starting heating in the period is calculated by the minimum value t min in the multiple water use starting time points t n obtained in the previous period, so that the user can use hot water immediately after returning home, heating is not required, and the user experience is improved.
In another embodiment, under the intelligent operation module, the heat generated by the electric heating element is controlled based on the maximum value Q max of the water heat quantity Q n obtained in the previous cycle.
Specifically, controlling the amount of heat generated by the electric heating element at the maximum value Q max for the plurality of water heat amounts Q n obtained in the previous cycle can ensure that the electric water heater heats enough heat to generate enough hot water for the user.
In some embodiments, in order to increase the hot water output rate, under the intelligent operation module, the electric heating component in the inner container provided with the water outlet pipe is started first, if the inner container is heated to the highest set temperature, the heat generated by the electric heating component is smaller than the water heat Q n, and then the electric heating component in the inner container provided with the water inlet pipe is started.
Specifically, for the electric water heater adopting the two inner containers, in the heating process, the water in the inner container provided with the water outlet pipe is heated first so as to ensure that the inner container has sufficient hot water output, and adverse effects of cold water introduced by the water inlet pipe on the hot water output rate can be reduced to the greatest extent.
