Description of drawings
Fig. 1 is circuit theory diagrams of the present invention.
Embodiment
Below in conjunction with embodiment and contrast accompanying drawing the present invention will be described.
Present embodiment is made up of transformer T1, the bridge rectifier D, delay capacitor C3, the first filter capacitor C1, the second filter capacitor C2, voltage stabilizing chip IC 1, voltage comparator ic 2, first to fourth resistance R 1-R4, switch triode Q1, the 5th diode D5 and the normally opened relay K1 that constitute D1-D4 by first to fourth diode.
Transformer T1 is elementary to connect the 220V civil power through fuse cutout F1; Realize that voltage 220V converts 12V into; The input end of T1 level of transformer cross-over connection bridge rectifier D; The bridge rectifier D cross-over connection is between the input end and ground end of voltage stabilizing chip IC 1, and voltage stabilizing chip IC 1 input end, output terminal are connected to the first filter capacitor C1 and the second filter capacitor C2 respectively, and first resistance R 1 and the cross-over connection of delay capacitor C3 series arm are between voltage stabilizing chip IC 1 output terminal and ground end; Constitute the RC delay circuit, intermediate contact connects voltage comparator ic 2 voltage negative terminal input end pin 2.First resistance R 1 is a fine delay resistance, in order to regulate delay time.Second resistance R 2, the 3 series arm cross-over connections of the 3rd resistance R are between voltage stabilizing chip IC 1 output terminal and ground end and 4 on voltage comparator ic 2 pin 8 and pin; Intermediate contact connects voltage comparator ic 2 voltage anode input end pin 3; Voltage comparator ic 2 output terminals connect triode Q1 base stage after being connected in series the 4th resistance R 4; Switch triode Q1 emitter meets normally opened relay K1, and the 5th diode D5 cross-over connection is between triode Q1 emitter and ground end.Normally opened relay output connects the starting switch of air-conditioning panel.
Present embodiment voltage stabilizing chip IC 1 adopts 7809 voltage stabilizing chips, and R1 is fine delay resistance (3296 precision resistor); R4 is the current limliting biasing resistor; The 5th diode D5 is a protection diode (1N4007)
Principle of work of the present invention is: the 220V civil power is through 220V/12V power transformer (T1) back output 12V alternating current.Through output ripple direct current behind (D1-D4) bridge rectifier, again through first filter capacitor (C1) filtering, again through voltage stabilizing chip output+9V.Through second filter capacitor (C2) filtering, this power supply is output as direct current+9V to the voltage stabilizing chip again.
Behind the circuit access+9V power supply, when power on circuitry, second resistance R 2, the 3rd resistance R 3 are formed the series connection bleeder circuits to make the homophase input reference voltage of voltage comparator ic 2 are 4.5V; Constitute the RC delay circuit by R1 and C3, T=R1 C3, R1 are fine delay resistance, the reverse input reference voltage of control voltage comparator.When voltage comparator in-phase input end voltage was higher than reverse input end voltage, voltage comparator output high level made switch triode S8050 conducting, and relay coil gets electric adhesive.(moving contact 1 is in normally open with stationary contact 3 when relay coil is not switched on; , relay coil transfers closure state to by normally open between moving contact 1 and the stationary contact 3 when switching on.) in R1 gave the C3 charging process, the reference voltage of the inverting input of voltage comparator slowly raise in this process, works as capacitor C
1Voltage charges to 4.5V when above, this moment voltage comparator in-phase input end voltage less than inverting input voltage, the voltage comparator output low level, thus the relay coil dead electricity discharges.
The big I that the present invention can regulate R1 changes the relay closes time.(the R1 resistance increases delay time and increases.Need 0.3S when internal circuit resetted when general air-conditioning was switched on).
