Abstract
The invention discloses an electronic temperature controller which comprises a relay, wherein a working circuit of the relay is controlled by an integrated block trigger control circuit; a trigger end and a reset end of an integrated block are connected in series with a first thermistor and a second thermistor respectively; the relay is a double-group relay which is connected with a compressor working circuit and a defrosting working circuit respectively; when temperature in a refrigerator rises, the resistance of the first thermistor is reduced, the voltage of the trigger end of an integrated circuit drops, and the relay is electrified to close the compressor working circuit; and when temperature in the refrigerator gradually drops, the resistance of the second thermistor is increased, the voltage of the reset end of the integrated circuit rises, the relay 4 trips off and is communicated with a normally closed contact, the compressor stops, and an automatic defrosting circuit is in a working state. The electronic temperature controller disclosed by the invention has the advantages of simple structure, low cost and stable performance, and is convenient to regulate.
Description
Technical field
The present invention relates to a kind of temperature controller, particularly a kind of electronic type temperature controller.
Background technology
The electronic temperature controller of refrigerator roughly divides two types at present; A kind of is the wet control of discrete component formula electronics device; The influence whether performance of this temperature controller is stablized by electronic component performance directly; In the environment that the temperature difference constantly changes, the performance parameter variations of electronic component is bigger, makes whole temperature controller control deviation, sensitivity low.Another kind is the ic-type temperature controller, adopts special-purpose integrated package, complex circuit, and the production difficulty is big, and cost is high, and difficulty is applicable to uses such as existing low and middle-grade refrigerators of China and refrigerator-freezer.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the object of the present invention is to provide a kind of electronic type temperature controller, have the advantage that stable performance, control accuracy are high, production cost is low.
For reaching above-mentioned purpose, technical scheme of the present invention is following:
A kind of electronic type temperature controller; Comprise relay 4; The operating circuit of relay 4 is controlled by the integrated package trigger control circuit; The trigger end of integrated package and reset terminal are serially connected with first thermistor 2 and second thermistor 3 respectively, and relay 4 is two group relaies, link to each other with the defrosting operating circuit with the compressor reducer operating circuit respectively.
Operation principle of the present invention is: when temperature in the refrigerator raise, first thermistor, 2 resistances diminished, and integrated circuit trigger end voltage descends; Relay 4 energising adhesive compressor reducer operating circuits, temperature descends gradually in the refrigerator, and second thermistor, 3 resistances increase; Integrated circuit reset terminal voltage rises; Relay 4 trippings are also connected with normally-closed contact, and compressor quits work, and the automatic defrosting circuit is then in running order.
The present invention has simple in structure, and is with low cost, stable performance, advantage easy to adjust.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed explanation.
Shown in accompanying drawing; A kind of electronic type temperature controller; Comprise relay 4, the operating circuit of relay 4 is by the control of integrated package trigger control circuit, and the trigger end of integrated package and reset terminal are serially connected with first thermistor 2 and second thermistor 3 respectively; Relay 4 is two group relaies, links to each other with the defrosting operating circuit with the compressor reducer operating circuit respectively.
Operation principle of the present invention is: when temperature in the refrigerator raise, first thermistor, 2 resistances diminished, and integrated circuit trigger end voltage descends; Relay 4 energising adhesive compressor reducer operating circuits, temperature descends gradually in the refrigerator, and second thermistor, 3 resistances increase; Integrated circuit reset terminal voltage rises; Relay 4 trippings are also connected with normally-closed contact, and compressor quits work, and the automatic defrosting circuit is then in running order.
In the accompanying drawing: 1 is integrated package; 2 is first thermistor; 3 is second thermistor; 4 is relay.
