Abstract
A micro-power consumption infrared inductive control circuit for an electric heater adopts a micro-power consumption voltage stabilizing power circuit connected in series with an LED (light emitting diode) as datum for monitoring and supplying power, selects a BISS001 chip for infrared inductive control, and adopts a bidirectional triode thyristor alternating-current switch circuit which is coupled and connected by a Phi3 red-light LED and a photoconductive resistor. The power supply of the electric heater is started by an infrared inductive monitoring circuit so as to achieve the purpose that the electric heater provides hot air when people move, and the electric heater stops work when people is still, and the power consumption quantity of the system is lower than 1 milliwatt; and the micro-power consumption infrared inductive control circuit has low design cost by adopting universal elements, simple structure and small volume, and can be widely used for automatic control of the electric heater.
Description
Affiliated technical field
The utility model relates to the little power consumption infrared induction of a kind of electric heater control circuit, can be widely used in electric heater and control automatically.
Background technology
Electric heater is an electrical equipment commonly used in winter, generally is to adopt mains switch control, and people's use habit has caused idle power consumption again, produces the wasting of resources.The current energy-saving low-carbon of advocating requires to provide a kind of little power consumption infrared induction electric heater control.
Summary of the invention
In order to adapt to people's use habit, it is warm to accomplish that the moving electric heater of people send, the quiet autostop of people, and the little power consumption infrared induction of the utility model electric heater control circuit, automatic power and time-delay keep, and after no human body moved, power supply was closed automatically.Can be widely used in electric heater controls automatically.
The technical scheme that its technical problem that solves the utility model adopts is: little power consumption stabilized voltage power supply of being done benchmark by LED, the little power consumption infrared thermal releasing of BISS001 control circuit, the bidirectional triode thyristor alternating current switching circuit that employing is of coupled connections by φ 3 red-light LEDs and photo resistance, the electric heater power supply is started by the infrared induction supervisory circuit, export several minutes delay control signal, bidirectional triode thyristor conducting power supply, after no human body moves, power supply is closed automatically, adopt universal component, low-power consumption, low cost, circuit power consumption is less than 1 milliwatt.
The beneficial effects of the utility model are, the people is moving to be sent warmly, and the quiet shutdown of people is controlled automatically, feels comfortable, energy-conservation economize on electricity.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is further specified.
Among the figure. be the little power consumption infrared induction of the utility model electric heater control circuit.
Specific embodiments
Among the figure. circuit is connected with AC network 220V, wherein an end is connected on the controlled fan power supply through bidirectional triode thyristor, the voltage stabilizing power supply of supervisory circuit: little power consumption voltage-stabilized power supply circuit of doing benchmark by LED, circuit is directly connected to AC power by 4007 positive poles, the current-limiting resistance R2 ground connection of connecting with two LED pipe D1, D2, the positive pole of D1 connects the NPN transistor base, there is 2uF electric capacity to connect over the ground, current-limiting resistance R 3 connects the NPN transistor collector, launch very circuit output end of pressure-stabilizing, have 470uF electric capacity to connect over the ground.
The infrared induction supervisory circuit: selecting chip BISS001 for use, is the little power consumption infrared thermal releasing of homemade low cost control circuit, has constituted the efficient low-consume function of infrared induction supervisory control system.
Time-delay control is by the setting of BISS001 peripheral cell.
The bidirectional triode thyristor alternating current switching circuit that employing is of coupled connections by φ 3 red-light LEDs and photo resistance, optocoupler assembly: be directly to be coupled by LED and photo resistance, and with outer light Isolated Shield, the photo resistance two ends directly are connected with bidirectional triode thyristor G end, A2 end, both simplified the silicon controlled drive circuit, because photo resistance is to drive silicon controlled by change in resistance, the characteristic of soft start is arranged simultaneously, help device power supply (DPS) safety and self alternating current switching circuit safety.
Among the figure. by strong switch SW is infrared induction control selector switch.
The little power consumption infrared induction of electric heater control circuit is widely used in electric heater and controls automatically.
