Description

Electronic timing universal switch

A kind of adjustable power electronic timing universal switch.

At present, household electrical appliance have entered huge numbers of families, and people are also more and more higher to its understanding and requirement.In daily life, people to the illumination of light, the rotating speed of electric fan, the requirement of the temperature of warmer is all different at different times.For example read newspaper or need brightness big when having a meal, the brightness that needs when seeing TV is little, only needs low-light during rest, and turn off the light automatically in sleeping back, shutdown (television set, electric fan, warmer etc.), guarantees Electrical Safety and electrical energy saving.Especially at present ceiling fan, warmer are not generally all installed timing device, have a rest to people and have brought inconvenience.

The purpose of this utility model provides a kind of household electrical appliance power of can regulating arbitrarily, and timing automatic is cut off the universal switch of household electrical appliance power supply, and it can guarantee Electrical Safety and electrical energy saving.

The purpose of this utility model is achieved in that it includes the RC phase shifting part by the band potentiometer of connecting on the electric loop, the power conditioning circuitry that element such as diac and bidirectional triode thyristor is formed, it is characterized in that: be parallel with by the DC voltage-stabilizing power pack at the power supply two ends of load, time base integrated package time-delay part, the timing control circuit that element such as power amplification and midget relay is formed, relay normally open contact is connected between the inlet wire of the live wire of AC power and load, in order to the connection and the shutoff of control load and AC power.

The utlity model has following advantage:

1, highly versatile.Can control illuminating lamp, the various household electrical appliance that 220W such as ceiling fan, warmer are following.It promptly has the function of " opening ", " pass " electrical appliance, again can be as required regularly or not timing and regulated at will electrical appliance power, thereby save a large amount of electric energy, guarantee Electrical Safety.

2. circuit is simple, and working stability is reliable, and cost is low, easily implements.

3, it is all very convenient to use, install, safeguard.

Accompanying drawing is circuit theory diagrams of the present utility model.

Describe concrete structure of the present utility model and operation principle in detail below in conjunction with drawings and Examples.

Referring to accompanying drawing, relay J normally opened contact J ₁Be connected between the live wire of 220V alternating current and the binding post of load (3) respectively with after push-button switch AN and functional select switch k are in parallel, between the binding post (4) of load and ground wire, be connected with resistance R respectively ₃, potentiometer W ₂, capacitor C ₅Phase-shift circuit and bidirectional triode thyristor SCR circuits for triggering, the control utmost point of bidirectional triode thyristor SCR is through diac ST, current-limiting resistance R ₄Be connected potentiometer W ₂Adjustable end on, can also in parallel one at the two ends of bidirectional triode thyristor SCR be used for the electric capacity of weakening and the anti-jamming circuit of resistance series connection.The direct-connected live wire of the contact of functional select switch k (2).Its contact (1) is through decompression capacitor C ₁As diode D ₁～D ₄An input of bridge rectifier, its another input end grounding, the output of bridge rectifier is by filter capacitor C ₂, behind the voltage stabilizing didoe DZ as the DC voltage-stabilizing power supply.Between the positive pole of dc power supply and negative pole, be connected with potentiometer W ₁And capacitor C ₃Delay circuit.The pin 6 of 555 time-base integrated circuit piece IC, pin 7 also connect back and capacitor C ₃Anodal linking to each other, pin 4, pin 8 also connect the back and link to each other with D.C. regulated power supply is anodal, pin 1, and pin 5 passes through capacitor C ₄Link to each other with the D.C. regulated power supply negative pole respectively, pin 3 outputs of integrated circuit block IC are through resistance R ₁R ₂After the dividing potential drop as the input of triode BG base stage, by the end of the collector electrode control midget relay J of triode BG, another termination D.C. regulated power supply positive pole of relay J, the emitter of three pipes connects negative pole.The diode D in parallel at the relay J two ends ₅Protective circuit.

Operation principle:

Electrical appliance is inserted load wiring terminal (3), (4), if when only needing to regulate the power of electrical appliance, functional select switch k is dialled to contact (2), use power governor this moment separately, and timing control circuit is consumed power not.The 220V alternating current by electrical appliance through resistance R ₃, potentiometer W ₂To capacitor C ₅Charging.Work as capacitor C ₅When the voltage at two ends is raised to greater than the blocking-up value of diac ST, the conducting in succession of diac ST and bidirectional triode thyristor, electrical appliance is started working.Regulator potentiometer W ₂Size, can change the size of the angle of flow, thus the watt level of regulated at will electrical appliance.As regulate the illumination of illuminating lamp, the rotating speed of ceiling fan, the temperature of warmer etc., to satisfy the needs of people's work and life.

If when when regulating the electrical appliance watt level, also needing regularly to use electrical appliance, then functional select switch k can be dialled tieback point (1), press starting button AN, the 220V alternating current is through capacitor C ₁Step-down, diode D ₁～D ₄Rectification, capacitor C ₂Filtering by voltage stabilizing didoe DZ output DC voltage-stabilizing electricity, is supplied with delay circuit.Work as capacitor C ₃When the voltage at two ends is raised to the turnover voltage of time-base integrated circuit piece IC, integrated circuit (IC) upset output, its output signal is through power amplifier control midget relay J, and it is electric that relay J is got, its normally opened contact J ₁Adhesive, self-locking.Meanwhile, the 220V alternating current is often opened contact J ₁, electrical appliance, bidirectional triode thyristor SCR constitutes the electricity consumption loop, thereby makes the electrical appliance timing working.Regulator potentiometer W ₁Size, can change capacitor C ₃Charging interval, reach function regularly.After having reached the delay time of regulation, the time base ic chip upset, the relay J dead electricity, normally opened contact discharges and resets, the electrical appliance outage quits work, timing automatic is turned off the light, the purpose of shutdown thereby reach, and guarantees Electrical Safety and electrical energy saving.
