Description
Technical field
The present invention relates to a kind of earthenware heater of heating liquid, particularly a kind of heater self-temperature of measuring changes the earthenware heater with temperature detecting resistance line that its resistance value also changes thereupon.
Background technology
Along with the development of science and technology, for the metal electric heat pipe that liquid or water heat, bare metal silk, quartz heating-pipes etc. have all highlighted deficiency in the application, but occurred that earthenware heater is as aluminium oxide heater in the market, silicon nitride heat generating body etc., the fail safe of the products such as the water heater manufactured with these earthenware heaters, surface is less scaling, the raising of the heat efficiency has positive effect, but because earthenware heater firing rate is fast, the temperature of earthenware heater moment itself is high, in 2 seconds, the temperature of earthenware heater itself can reach about 700 DEG C greatly, external temperature controls the change that transducer can not detect earthenware heater temperature directly and accurately, therefore just cannot be controlled effectively to its fracture at the earthenware heater preventing dry combustion method body from causing itself.Owing to there is this problem, with the product that earthenware heater manufactures, as quick electric water heater, fast electric heating fire hose first-class product, also the 3C certification of country cannot be smoothly through, therefore the heat condition of earthenware heater itself effectively, is detected directly and accurately, control to ensure the operating state that earthenware heater is safe and reliable when dry combustion method, earthenware heater could be allowed to be widely used.
In sum, if earthenware heater can not Detection & Controling dry combustion method exactly, be the bottleneck of earthenware heater application, have a strong impact on popularization and the use of this product.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, earthenware heater with temperature detecting resistance line is provided, resistive conductor is fabricated directly on earthenware heater, it not only structure simply, do not need the external form and the structure that change former earthenware heater, use reliable, security performance is good, and resistive conductor can reflect the variations in temperature of earthenware heater itself fast, accurately and timely, reaches the object promptly and accurately controlled with preventing dry combustion method.
The present invention's adopted technical scheme that solves the problem is: comprise between the ceramic die of earthenware heater and outsourcing ceramic sheet and have line with heating function, line with heating function terminals L, line with heating function terminals N; The ceramic die of described earthenware heater and outsourcing ceramic sheet have resistive conductor, described earthenware heater has resistive conductor terminals A and resistive conductor terminals B.
Compared with prior art, the present invention is with the earthenware heater of temperature detecting resistance line, comprise between the ceramic die of earthenware heater and outsourcing ceramic sheet and have line with heating function, line with heating function terminals L, line with heating function terminals N, connect with the mains at line with heating function terminals L, line with heating function terminals N, line with heating function generates heat instantaneously on earthenware heater, resistive conductor is had between the ceramic die of earthenware heater and outsourcing ceramic sheet, the ratio that the composition of the material tungstenic of resistive conductor accounts for total amount is greater than 50%, other materials is added according to different needs, the resistance value of resistive conductor when ambient temperature 25 DEG C is made to be greater than 10 Europe, be less than 10 kilo-ohms, resistive conductor is while earthenware heater generates heat instantaneously, resistance on resistive conductor changes by the change of earthenware heater temperature, resistance variations on resistive conductor detects the change of earthenware heater temperature in time, by the resistive conductor terminals A on earthenware heater and resistive conductor terminals B, controller is related in the change of resistance value, thus reach the through and off controlling earthenware heating unit power, reach the object controlled with preventing dry combustion method, ensure earthenware heater safety and work reliably.
Adopt this structure, earthenware heater has high heat conductance good heat conductive and insulation property, its firing rate is fast, fail safe is good, and mechanical strength is good, not easy fracture, do not need to change original earthenware heater external form and structure, easily manufacture, easy to use, greatly improve useful life and the range of application of earthenware heater.
