Solution of internal structure of electric water heater

1. inner container

The inner container is the core component of the water heater, which directly affects the safety performance, service performance and working life of the water heater.

2. magnesium rod

The main function is to protect the electric heating rod, which is easy to react with minerals in water when heated, thus reducing the service life of the electric heating rod.

3. Safety valve

Safety valves are also called check valves, check valves and pressure relief valves.

4. Anti-electricity wall

It is to use the resistance of water itself (for example, the national standard stipulates that the resistivity of tap water should be greater than1300Ω at 15℃), and form an "insulation wall" by selecting the material (insulation material), pipe diameter and distance of the water heater.

5. heating rod

The electric energy → heat energy conversion device is mainly used for heating water, with the power of 1, 500 W-3000 W, and is mainly composed of heating resistance wires, copper pipes or stainless steel pipes, magnesium oxide as a heat conducting and insulating medium and terminals.

Extended data:

Working principle of electric water heater:

After the water storage electric water heater is electrified, the electric heating tube in the electric water heater heats the water in the inner container of the electric water heater. When the water is heated to the set temperature, the circuit is automatically disconnected, the electric heating tube stops heating, and the whole machine is in a heat preservation state.

When the water temperature in the inner container drops to a certain temperature, the electric heating tube is electrified and heated again, and this state is repeated, so that hot water is always available for the electric water heater.
