Description

A kind of electric heating system of constant temperature changeable parameters
Technical field
The present invention relates to a kind of electric heating system, a kind of electric heating system of constant temperature changeable parameters particularly, it has temperature controlled, heating material is nonmetallic heater.
Background technology
The constant-temperature control method of traditional electrical heating system normally adopts the variation of heat detecting sensor temperature, and the heating operation that is then fed back to heating element compensates occurred variations in temperature.Its shortcoming is more complicated, price, yet its reliability is not high.In recent years, positive temperature coefficient (Positive Temperature Coefficient, PTC) development and application of temperature-sensitive element heating technique has obtained considerable progress, for domain of control temperature provide a kind of simple, price is suitable and the heating of high reliability and temperature are controlled integrated heating and temperature control unit.Yet the application of this technology still can not be fully up to expectations.
US Patent No. 5283420, on May 6 1991 applying date, title " Electrically heated beverage container " discloses a kind of for the electric heating container for drink in automobile.In this invention, ptc heater by soldering one, can conduct electricity, the inner bag bottom outside of heat conduction, two one of electrode bars are welded in ptc heater lower surface, another is welded in inner bag bottom lower surface; Heat-insulation layer is arranged at wall of cup and part bottom, and an anterior band chamfer groove is arranged at cup bottom, and two electrodes are positioned at this groove.Corresponding this groove, has two parallel strip projections, the middle inside of two strip projections to have a pair of spring conducting strip corresponding with glass top electrode providing on the cup of power supply, has an isolating bar that two spring conducting strips are kept apart between two spring conducting strips; There is the kick with slope the front portion of this isolating bar, and there is another little rectangular recess at the anterior chamfering of groove at cup corresponding to it place.When cup is placed on cup, the anterior chamfering of the groove of cup can play guiding function, the kick of cup isolating bar front portion can play the role of positioning with another little rectangular recess at the anterior chamfering of the groove place of cup, guarantee that two electrodes on cup accurately contact with two spring conducting strips on cup, and guarantee that cup does not move on cup.Two spring conducting strips on cup connect power line, have a mains switch on power line, and power line connects an igniter for automobile plug.
US Patent No. 6192787, on November 3 1997 applying date, title " Electrically heated beverage appliance ", discloses a kind of electric heating beverage appliance.In this invention, the cup end is conduction, Heat Conduction Material, adopts sealing strip to be connected with wall of cup with locking strip, at the bottom of PTC heating element is directly welded in glass on, on bowl cover, have a plurality of holes to supply to drink, have the swivelling cover that these holes can be blocked; Provide on the cup of power supply and have three electrodes, the middle PTC heating element that directly connects, one of side is the power supply of PTC heating element for a cup end that connects conduction, at the bottom of another one also connects glass, but connect indicator light, carry out display operation state, on cup, have cylindricality ring, be used for cup to locate.
US Patent No. 6121585, on March 30 1999 applying date, title " Electrically heated beverage cup and cupholder system ", discloses a kind of electric heating goblet and cup system.In this patent, wall of cup adopts plastic material,, there is a metallic plate at the cup end, between this metallic plate and wall of cup, adopt the sealing of O shape ring, under this metallic plate, have a polymer flexibility PTC heating plate, the electrode of this heating plate is the platform shape projected electrode of Jie Bei bottom centre and the projected electrode of the ring-type of cup feather edge respectively, and cup bottom section body adopts plastic material, bottom cup with between wall of cup, adopt ultrasonic bonding or bonding way to be connected, the equilibrium temperature of this ptc polymer is approximately 48.9~82.2 ℃, the periphery that the cup of power supply is provided is a raised annular external wall structure, the inside of this annular external wall structure is the ring-shaped platform at the bottom of a support cup, there is recessed an of circle at the center of this platform, this platform edges be one with central fovea below recessed of concentric annular, in recessed of recessed of the central circular of this cup and annular, there is respectively a spring pellet electrode, two recessed of described cup is corresponding identical with the platform shape projected electrode of cup bottom and the projected electrode of ring-type respectively with electrode wherein, the sensitive switch that also can trigger below of one of spring pellet electrode of described cup prevents that other conduction foreign matter is placed on and on cup, causes power supply short circuit.
The deficiencies in the prior art part is that the steady temperature of ptc heater used is fixed, and user cannot maybe need to regulate at any time according to its hobby.In other words, although traditional constant-temperature control method is complicated, it has constant temperature simultaneously and constant temperature is put adjustable function, and after it is replaced by ptc heater, although its temperature persistance is very superior, its constant temperature point becomes unadjustable.The shortcoming of other also has: cup has limited the size at the cup end; The unreasonable of cup seat structure takes off cup and puts the inconvenient operation toward cup; Cup can not be placed in the existing cup of automobile; Cup does not have heat insulation function; Power supply is not had to applicability widely; The structure of cup is more single etc.In a word, these shortcomings are used and have been brought many inconvenience to cup.
If from scope and angle widely, existingly by the heating system that PTC heating element replaces traditional heater, there is same problem, the self-constant temperature parameter of PTC is utilized well, yet, tend in actual applications need to choose because of the difference of various complicated situations or demand the PTC heating element of different constant temperature parameters, but owing to using the heater that can not change or switch PTC heating element, its constant temperature parameter (Curie temperature Tc, surface temperature Tsurf, temperature coefficient α, specified zero power resistance R25 etc.) be changeless, this has limited PTC to a certain extent in the more application of broad range.
