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 technology, a heat-insulating layer is usually formed by adopting a foaming mode.

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.
