Description
Technical field:
The flashing temperature controller that utility model has two bimetal leafs belongs to domain of control temperature, is suitable for the electric heating electric appliances, be suitable for especially home-use electric cooker, electric iron, electric frying pan, electric blanket, etc. small household appliances use.
Background technology:
Temperature controller is divided into control of slow motion formula and flashing control two big classes usually, and slow motion formula thermostat is metal heated distortion, drives contact at leisure and moves, and contact is disengaged.Existing flashing temperature controller is by the bimetal leaf of monolithic, the spring contact assembly, pressing plate and insulating part are formed, bimetal leaf is linked by two kinds of different metals, the deformation coefficient of different metal is different, when ambient temperature changes, two kinds of metal strains are different to cause the bimetal leaf bending, this crooked promotion spring assembly displacement, after reaching certain position, spring assembly produces snap action, it is flashing, make contact disconnect the electric current of more or less connecting the heating original paper, thereby object temperature is controlled.
At present, the about 20 ℃ of insulation degree as electric cooker of temperature difference that make the bi-metal plate deformed of bimetal leaf temperature controller reach the spring assembly action are 69 ℃, when the bimetal leaf temperature reaches 69 ℃, the contact that bimetal leaf promotes the spring contact assembly breaks away from, contact is resetted, then want the bimetal leaf temperature to descend about 20 ℃, promptly the bimetal leaf temperature about 49 ℃ this moment bimetal leaf deformation position just can make contact closure on the spring assembly.So, monolithic bimetal leaf flashing temperature controller requires the controlled environment variations in temperature bigger, the time of temperature control and the stability of object temperature have been influenced, also influenced simultaneously the quality of controlled thing, object or biological being difficult in this environment are adapted to, insulation differs from 20 ℃ as rice, and the time, long meeting was rotten.The biological environment time 20 ℃ of the temperature difference, long just being difficult to adapted to.
The temperature control time has been grown and has caused controlled thing rotten, has grown as the rice insulation time, will be spoiled, can not eat.
Summary of the invention:
The flashing temperature controller that utility model has two bimetal leafs its objective is and will overcome the big shortcoming of the action temperature difference that existing monolithic bi-metal plate deformed resets, the deformed movement temperature is dwindled about one times.
The utility model adopts the structure of two bimetal leafs, and the distortion of two bimetal leafs, both distortion promote the spring contact assembly simultaneously and produce the stack distortion, shortens the time of distortion.
Flashing temperature controller with two bimetal leafs, by bimetal leaf, spring contact assembly, pressing plate, decide contact and insulating part is formed, they link together with bolt, insulating part is arranged each other, pressing plate is upper, spring contact assembly and decide contact in the centre position, bimetal leaf is the next or be called bimetal leaf down, and the moving contact on the spring contact assembly contacts decides contact; It is characterized in that pressing plate is made up of last bimetal leaf, last bimetallic is fixed together by two kinds of different metal sheets, and upper and lower bimetal leaf is installed in spring contact assembly upper and lower respectively symmetrically.
The described bimetal leaf of going up is characterized in that on this that bimetal leaf is by two kinds of different metal clinkerings or bond together.
Described bimetal leaf and the following bimetal leaf gone up when it is characterized in that bimetal leaf and following bimetal leaf are installed, make two sheet metals produce symmetry flexural deformation with respect to spring part.
The material trademark of described upper and lower bimetal leaf can be identical or inequality with shape.
The spring contact assembly of above-mentioned temperature controller, it is characterized in that the moving contact of spring contact assembly and the contact of deciding on two metallic conduction sheets form two current switches, wherein the contact of deciding on metallic conduction sheet is with the metallic screw contact that is threaded on the conducting strip, the contact of deciding on another piece metallic conduction sheet is the contact that is fixed on the metallic conduction sheet, there is the conducting strip of metallic screw contact to be installed in the top of the moving contact of spring contact assembly, be the below that contact is installed in the moving contact of spring contact assembly of deciding of contact on another piece metallic conduction sheet, the center line of screw contact overlaps with moving contact and contact contact center line.
Above-mentioned temperature controller is characterized in that temperature adjusting structure is arranged, and this structure is made up of adjustable rod and stator, adjustable rod is the what stator fixedly, the upper and lower motion of energy, the lower surface of adjustable rod is pressed in the screw end face of bimetal leaf, and stator is fixed on the top of bimetal leaf.
The described bimetal leaf of going up is characterized in that this bimetal leaf has one section arcuate structure.
The adjustable rod of described temperature adjusting structure is characterized in that adjustable rod is a bolt.
Flashing temperature controller with two bimetal leafs is simple in structure, and the energy temperature adjustment, and the action that bi-metal plate deformed resets has a narrow range of temperature.
