What is the principle of electric water heater? Analysis of working principle of electric water heater

Electric water heater is a technology product closely related to our life. It brings considerable convenience to our life. So do you know the principle of electric water heater ? The following decoration home decoration network Xiaobian will bring you the analysis of the working principle of electric water heaters, hoping to provide help for everyone.

What is the principle of electric water heater?

The electric water heater is heated and unheated through the on and off of the thermostat. The general concept of insulation is short-time heating. When heating, the rated power of the water heater is still used. After the circuit is connected, if the water temperature is lower than 50 °C (most brand set critical temperature), the thermostat is automatically turned on, the water heater is heated at the beginning, and the water temperature reaches the preset temperature of the water heater (most brands are 75 ° C ~ 85 ° C When the thermostat is turned off, the water heater stops heating.

The so-called insulation is completed by the insulation layer of the water heater. As the water temperature drops from time to time, until the temperature is lower than 50 °C, the water heater starts to heat again. This cycle reciprocates and completes the so-called insulation. When the amount of heat is kept, the water heater does not consume electricity, which is close to the theoretical zero power and zero power consumption. When heating, the water heater uses the rated power. To understand the uniform power consumption of the water heater insulation, look at the national standard can be. The approximate value is that even if a drop of hot water is not used, the power consumption of the water heater only "insulation" is about 2 degrees / 24 hours.

Working principle of electric water heater:

1. The working principle of the hot electric water heater; there are many components of the hot electric water heater, which are mainly composed of a heating trough plate, a power regulator, a water regulating faucet, a pressure sensor, and an inlet pipe and an outlet pipe. Among all of these components, the heated trough plate is a key component of the instant electric water heater, consisting of a seal ring, a slot, a cover and an electric heating element, and the other electric heating elements are in the slots of the slot plate. In the work, the instant electric water heater adopts the direct conduction heating method, because the electric heating element is in the groove of the groove plate, so when the cold water flows through the groove, it can be heated directly through the surface of the electric heating element. At the same time, because the groove plate is serpentine, the water is gradually heated when it passes, and the water becomes very hot when it is exported.

2. Working principle of water storage type electric water heater: The main structure of water storage type electric water heater includes insulation layer, internal service, temperature controller, heating tube and magnesium rod, etc. The inner tank of water heater is composed of stainless steel plate, electric water heater belt It has leakage protection, anti-dry protection and over-temperature protection. When the water storage type electric water heater is energized and heated, the heating indicator light will be on. When the water temperature reaches the set temperature, the thermostat contact will be disconnected, and the heating will be stopped. Different insulation layers have different effects, and the speed of temperature reduction will also vary. Generally, it will be about 7 degrees Celsius lower than the set temperature , and the water heater will re-enter the heating state. If the water heater is in dry or over-temperature condition, the bimetal of the overheat protector is closed, so that the test button contact on the leakage protection plug is short-circuited, and the leakage protection plug starts to operate to de-energize the heating tube. When the water temperature of the water heater is lower than the temperature of the overheat protector by 25 degrees Celsius, press the reset button on the leakage protector, and the electric water heater will return to the normal state.

The above is what is the principle of electric water heater brought by Xiaobian? The whole analysis of the working principle of electric water heaters, I believe that everyone has a basic understanding of the principle of electric water heater after reading this article, if you want to know more about decoration consultation, please click to enter the decoration knowledge channel .
