The utility model skill area attributed an electric heater, specifically with anti-dry apparatus is a quartz heater. Whether metal heater skill sets are still able to take the initiative to fill quartz heater temperature heating, the first to rely on equipment in the electric heater inside the sudden jump bimetal control its temperature. When a solar water heater tank temperature below 40. C, the sudden jump bimetallic thermostat will automatically power the heater operation, when the water temperature reaches the set temperature is usually 60 ℃, the thermostat can take the initiative to open, suspend operation of the heater, water tank enter the insulation condition, user bathing, laundry, cooking can be. When the water temperature drops below 40 ℃, the thermostat heating power again, and so on ad infinitum cycle operation the tank temperature is kept at 40 aC above, 60 ℃ or less, satisfied customers affected by the rainy day when you can still assisted by electroporation to fill the heating temperature of the heater to ensure hot water every day throughout the year. However, these electric heaters, there are many questions about his assistant, a common question is the temperature increase is not on, with a very short time is not heating up, especially metal heating tube, a simple knot hard scale, heating pipes burst appearance is also a short circuit when attack, thanks to the leakage maintainer can play effect. Serious is when the heating pipe water dry when under the effect of the built-in thermostat reaches the set temperature point, temporarily disconnect the power to suspend the heating can certainly value when the temperature dropped, the effect of the heater thermostat will scratch under heating, in which long-time repeat dry conditions, the metal heating pipes will burst, electric eventually blown, no longer work. The quartz glass heater is not the same, except it does not bear hard scale and are not afraid to thermal shock, but can not be received one 00 hours dry burst, electric wire burn is not bad, there is an alternative to metal heating tube trends. But so will bring more serious question: Because dry quartz heater resistance ability, high thermal efficiency, and then causing the host foam insulation burned. The utility model to create content intended to depict an anti-dry quartz heating tubes, electric heater to prevent damage due to dry to extend the use of electric heaters and water life. Supply in accordance with the skill of the utility model program, the quartz tube closed at one end, the other end opening in the quartz tube and has a spiral coil wound on the electric wire, the open end of the quartz tube with silicone rubber seals, the silicone rubber ring seal seat outside the silicon rubber gasket seal convergence with the quartz tube, electric wire using wire and terminal equipment for sealing seat interface, and its features are: silicon rubber seals on the thermally conductive sheet, the thermal film located outside the quartz tube, one end of which near the open end of the quartz tube, the other end of the sealing device in a PTC thermistor seat convergence. Set the seal seat cover, PTC thermistor element and parting terminal located within the enclosure, the casing is set on the power cord for wiring bored hole. In the seal seat equipment thermostats, electric wire after wire and terminal convergence convergence with the thermostat. Perhaps, in the seal seat device has a thermostat, electric wire after wire and terminal convergence with PTC thermistor element and thermostat convergence. In a quartz tube close to the opening end of the spiral portion is provided for fixing the fixed refractory member. In the open end of the quartz tube wiring fixing member, the outer end of the wire fixing member touching the silicone rubber seal, the inner terminal end of the terminal fixing member fixed to the outer end positioned in the sealing seat. The utility model’s strengths are: the use of electric heating in the solar water heater temperature compensation, once the attack without water heater tank dry, packed in quartz electric heater maintenance of equipment within the anti-dry feel PTC thermistor element thermal film transfer heat, can automatically cut off the power of the heater stop the heating. Users to eliminate dry trouble before, regardless of whether the electric heater temperature dropped to reset temperature, anti-dry maintenance of equipment are no longer command the heating wire operation. Troubleshooting is simple: cut off the power first, check whether the leaking water heater tank, Sheung Shui function can fail; under normal after the tank is filled with water, convinced trouble condition after the power is turned on to eliminate the heater turn normal operation. Quartz electric heating and anti-one thousand burning assisted integration skills effectively safeguarding the successful development of the electric heater safety, to prevent the onset of fire incidents, and gave users a safe and convenient
