Abstract
A temperature controller comprises a temperature control and temperature regulation circuit, an operating status indication circuit and an overheat protection circuit, and is characterized in that the temperature control and temperature regulation circuit adopts a double-sheet metal temperature controller, and the triggering voltage of a bidirectional thyristor is controlled by the electric contacts of the double-sheet metal temperature controller, so that an electric heater is controlled to heat. The temperature controller can be used in industrial production, rural electric heating control and other works. The temperature controller not only can be used as an upgrading and new-generation device for the temperature control of indigenous brooding boxes of farmers, but also can be developed as an individual product.
Description
Technical field
The invention belongs to the Electrical Control Technology field, relate to a kind of temperature controller, it is applicable to the work such as rural area poultry hatching, edible fungus species cultivation or industrial laboratories.
Background technology
At present, the poultry that some conditions are good has been used electric blanket instead as heating arrangement.Their ubiquities hatch the temperature inside the box wayward, have outstanding problems such as incubation rate is lower, the cost of brooding is high, labour intensity is larger.Therefore, along with the rural electricity consumption problem generally is resolved, be necessary to develop a kind of simple in structure, dependable performance, temperature controller with low cost, easy to use.Temperature controller of the present invention can be widely used in the work such as poultry hatches, edible fungus species cultivation, artificial breeding, and in the past these work that solved are subject to the impact of the factors such as environment temperature, artificial treatment.
The present invention adopts a small amount of components and parts to form automatic temperature controller, and the components and parts price is low, dependable performance, and this temperature controller can be used for the work such as commercial production and rural area electric heating control.
Summary of the invention
Goal of the invention and beneficial effect: adopt a small amount of components and parts to form automatic temperature controller, this temperature controller can be used for the work such as commercial production and rural area electric heating control.The present invention both can be used as the temperature controlled upgrading of peasant household's local method Brooding cases, replacement device, also can be used as independent product and developed.
Technical characterictic: temperature controller is comprised of temperature control and temperature regulation circuit, working state indicating circuit, overheating protection circuit; it is characterized in that temperature control and temperature regulation circuit use bimetal chip thermostat; controlled the trigger voltage of bidirectional thyristor by the electric contact of bimetal chip thermostat, and then the heating of control electric heater.
The annexation that each several part the electric circuit constitute and components and parts thereof are mutual
1. temperature is controlled and temperature regulation circuit: be comprised of bimetal chip thermostat ST, resistance R 3, bidirectional thyristor VT, the first main pole T1 of the termination bidirectional thyristor VT of bimetal chip thermostat ST, the end of the other end connecting resistance R3 of bimetal chip thermostat ST, the gate pole G of another termination bidirectional thyristor VT of resistance R 3, the second main pole T2 of bidirectional thyristor VT connects the lower end of electric heater EH.
2. working state indicating circuit: formed by LED 1 and LED2, dropping resistor R1 and R2, the negative pole of LED 1 meets the first main pole T1 of bidirectional thyristor VT, meet the middle line end N of civil power behind the positive pole serial connection dropping resistor R1 of LED 1, the negative pole of LED 2 meets the second main pole T2 of bidirectional thyristor VT, meets the middle line end N of civil power behind the positive pole serial connection dropping resistor R2 of LED 2.
3. overheating protection circuit: U forms by thermal fuse F, the live wire end L of the termination civil power of thermal fuse F U, the first main pole T1 of another termination bidirectional thyristor VT of thermal fuse F U.
Principle of work: when temperature was low, bimetal chip thermostat ST's was electrical contacts closed, triggered bidirectional thyristor VT conducting, the electric heater EH heating of switching on.After temperature rises to design temperature, the electric contact of bimetal chip thermostat ST disconnects, bidirectional thyristor VT turn-offs, electric heater EH stopped heating, temperature begins to descend gradually, when drop in temperature behind design temperature, the electric contact auto-closing of bimetal chip thermostat ST, again trigger bidirectional thyristor VT conducting, the electric heater EH heating of switching on again.So go round and begin again, make temperature maintain desired temperature near, reach the automatically purpose of control of temperature.
