Description
Technical field the present invention relates to the electric formula heater of a kind of two resistances, can be widely used in the immediately heating water heater.
Background technology is present, common immediately heating water heater on the market, and its heater is generally titanium steel bowl, anaerobic red copper, metal coating quartz ampoule, and these heaters are because design feature separately all exists separately shortcoming with not enough.The intensification of titanium and red copper is inhomogeneous, produces easily incrustation scale, the corrosion electric leakage.The internal-external temperature difference of quartz ampoule is large, easy booster, and water power links to each other behind the booster, makes personal safety be subject to great threat.And these heater electric conversion efficiencies are low.
Summary of the invention the object of the present invention is to provide a kind of simple in structure, the thermal efficiency is high, heater element heat radiation is even, safe and reliable, the electric formula heater of two resistances of long service life.
In order to achieve the above object, the electric formula heater of the two resistances of the present invention, comprise insulation outer wall ellipsoid, it is inner and surround several ceramic rods of heat tunnel to be installed in insulation outer wall ellipsoid, insert the heating wire in the heat tunnel, be positioned at the obstruct electricity water stream channel that the heat tunnel both sides are installed in insulation outer wall ellipsoid inside, the water inlet joint that insulation outer wall ellipsoid lower side arranges, the delivery port joint that insulation outer wall ellipsoid bottom arranges, insulation outer wall ellipsoid top, upper heating wire nut connector and lower heating wire nut connector that the bottom arranges respectively, temperature sensor joint and grounding wire connector that insulation outer wall ellipsoid top arranges are installed in the connection seal gasket in insulation outer wall ellipsoid top and the bottom; Link to each other with connecting seal gasket between the electric water stream channel of said obstruct.
The electric formula heater of the two resistances of the present invention, said insulation outer wall ellipsoid, its outer wall adopt insulating materials to make.
The electric formula heater of the two resistances of the present invention, said several ceramic rods that surround heat tunnel can be three.
The electric formula heater of the two resistances of the present invention, said several ceramic rods that surround heat tunnel are not limited to three, even more.Heating wire heats in the heat tunnel that ceramic rod surrounds.
The electric formula heater of the two resistances of the present invention burns out the insulation outer wall for preventing the heating wire heating, in available several ceramic rods are wrapped in heating wire.The present invention advances the pipeline of cold water and goes out the pipeline of hot water, utilizes anti-electric wall principle, and when the water flow passage long enough, current are equivalent to the resistance of two approach infinities in this two ends runner, and the voltage that arrives human body is zero substantially.So that this heat-generating system without any electric leakage potential safety hazard, become traditional passive anticreep into initiatively every electric leakage, fundamentally guaranteed user's safety.
The electric formula heater of the two resistances of the present invention, " anti-electric wall " is a kind of abbreviation, its definite Description Method should be " water resistance decay isolation method ".In common people's understanding, water is a kind of conductor, with the danger that electrically contacts very.In fact, any object all has resistance, therefore, just may be transformed into the utensil that meets people's needs under the prerequisite of economy and brings benefit to the mankind meeting.Water resistance decay isolation method is exactly the resistance that has utilized water itself to have, resistivity should be greater than 1300 Ω cm 15 ℃ the time such as GB regulation running water, by the selection to water service pipe material insulating materials in the electric heater, caliber and distance are shaped as " electricity-isolation wall " really.When electric heater energising work, even the water of heating inner liner has electricity, also can be by " electricity-isolation wall " time be fallen to reach purpose with the electricity isolation by the resistance decrement of water itself, the voltage and the following atomic weak current of 0.02mA/kW that water heater Inlet and outlet water two ends are reached be close to zero." electricity-isolation wall " technology is adopted in the effect of anti-electric wall, not only can intercept the issuable electric leakage of electric heater itself, also can intercept because of ground wire electrification or the charged security threat that people are brought of water pipe, can fully guarantee personal safety.The electric formula heater of the two resistances of the present invention, heater element can adopt the nickel alloy heating wire, directly heats in water channel, and heat moment of generation is all taken away by water, and empty calory scatters and disappears, so that the thermal energy conversion efficiency of this technical approach is near 100%.
The electric formula heater of the two resistances of the present invention, heating wire is arranged in a spiral manner, and the water that produces after the heating also flows out with rotation mode, and the hot water water temperature after the heating is extremely even thus, temperature stabilization.
The electric formula heater of the two resistances of the present invention, there is not immobilising water in the heat-generating system pipeline, the hot water temperature utilizes circuit board to be controlled in 50 ℃, and the temperature on heater element surface can not surpass 50 ℃ thus, so this heating technique has fundamentally been rooted out the necessary condition that incrustation scale forms.Therefore, incrustation scale can't form, and temperature is low, and the heating wire life-span is long.
In sum, the electric formula heater of the two resistances of the present invention, simple in structure, the thermal efficiency is high, and the heater element heat radiation is evenly, and is safe and reliable, long service life.
