Electric water heaters are indispensable necessities for every household, but there are many problems. Many water heaters require a long heating time, and non-constant temperature brings hot and cold water easily to catch colds, etc., and with the development of technology It also brings greater protection to our lives. Constant temperature electric water heaters can greatly improve this. Constant temperature technology makes our lives more convenient. Come and feel a different electric water heater.

At present, most instant electric water heaters do not mix cold water. The principle of achieving constant temperature is: the water heater has a built-in stepping motor to test the water flow of the water inlet pipe and convert it into an electrical signal to be input to the motherboard processor. There is a temperature sensor on the water outlet pipe. The temperature result obtained will also be input to the motherboard processor. After calculation by the processor, the heating tube is controlled according to the result and the heating power is adjusted to achieve a constant temperature of the outlet water.

The so-called dry heating does not necessarily mean that there is no water at all. When the power of the electric water heater is large, it emits a lot of heat, and the water in the heater is small, and the circulation is very slow. At this time, it can still be regarded as the water heater is in Dry burning is also called partial dry burning, and this kind of dry burning cannot be completely prevented. For example, when the heating is stopped after a shower, the water in the heater is very small and the circulation has stopped. Although the power supply is turned off at this time, the heating temperature of the heating wire and the heating film is high, and a lot of residual heat is stored in the heating body. This residual heat can cause the temperature of the heating element to rise sharply, causing the heating element to produce a local dry burning phenomenon, causing the heating element to be traumatized and damaged. Therefore, we often hear that some salespersons who sell electric heating wires and electric film electric water heaters repeatedly urge customers to turn on the water first, then turn on the electricity, and turn off the electricity first and then turn off the water when shutting down. The reason is to slow down Dry burn generated during shutdown.

Secondly, during use, due to unstable water pressure and inflation of water pipes, the water flow rate will drop sharply, which will also cause partial dry burning of the electric water heater, which cannot be fundamentally prevented.

The anti-dry burning means that the heating element can work normally for a long time without being damaged even in the dry burning state, that is, it is fundamentally not afraid of dry burning. The semiconductor heater is a rare anti-dry heater. Ognor constant temperature instant electric water heater adopts this kind of semiconductor ceramic heater which is not afraid of dry burning.

The anti-drying of instant electric water heater mainly relies on the hydroelectric linkage valve. After a long time of use, the surface of the magnetic valve will be severely polluted or adsorb a large amount of iron filings, causing the magnetic valve to be unable to reset in time after the water heater is cut off, resulting in the inside of the water heater. The water has stopped circulating but the circuits have not been disconnected at the same time. At this time, the constant-temperature instant electric water heater is in a dry state, causing the water heater to be damaged due to high temperature in a short time.
