Skills area

The utility model belongs to an electric heater, in particular to a quartz with an anti dry burning device

Electric heater.

Scenery skills

Both the metal heater and the quartz heater can actively warm up the temperature, and the temperature is controlled mainly by the abrupt bimetallic strip in the electric heater. When the solar water heater tank, water temperature is less than 40. C, jump type double metal thermostat will take the initiative to connect the power supply to the heater operation, when the water temperature reaches the set temperature is 60 DEG C, the temperature controller and the heater can automatically disconnected, suspension of operation, the tank into the insulation, bathing, washing, cooking can be user. When the water temperature dropped to 40 degrees Celsius, the thermostat again the power supply is switched on, so the water temperature in the operation cycle of more than 40 aC, 60 DEG C, the user can still satisfied by electric heater heating assisted to fill in rainy days when there is hot water to ensure the four seasons of the year every day.

However, these electric heaters help exist many questions, the common question is not on the temperature, with a very short time without heating, especially metal heating tube, simple hard scale, electrothermal tube burst short circuit is formed when there is representation attacks, thanks to the leakage protection implement can have effect. Serious is when the electric heating pipe water dry, the built-in thermostat effect reaches the set temperature, can temporarily disconnect the power to suspend the heating, when the temperature dropped to a certain value, the heater will head heated in the thermostat effect, in this long time repeated dry conditions, metal the electric heating tube will burst, heating will burn, no homework. And quartz glass heater is not the same, it does not have a hard scale, not afraid of cold, hot, can accept 100 hours of dry burning will not burst, electric wire burning is not bad, there is a substitute for metal electric heating pipe development trend. However, it will bring more serious questions: because the quartz heater has the advantages of anti dry burning ability and high thermal efficiency, and then causes the host foam insulation layer to burn out.
