After provided with the controller, the water drinking machine not only can save power energy of 20 to 40 percent, but also can prolong the service life of the water drinking machine. CMOS integrate circuit and the output of the non-door controlling circuit is connected with the main control circuit, and the main control circuit is synchronously connected to the input power supply to supply the voltage for output power supply. The utility model can be used for the water drinking machine with different type.

Description

The light-operated controller that is used for water dispenser

Technical field

The utility model relates to electronic controller, especially a kind of light-operated controller that is used for water dispenser.Be applicable to the water dispenser of any kind of.

Background technology

Water dispenser has generally entered ordinary family and office space in recent years, the demand of water dispenser increases substantially, following a problem of appearance simultaneously is that electric energy expends increase, because existing water dispenser does not have the design of energy-conservation aspect, water dispenser is in all weather operations state substantially, not only waste energy, and shortened the service life of water dispenser.Do not cause waste of energy to reach about 20-40% when according to investigations, water dispenser is not worked.

Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of light-operated controller that is used for water dispenser that utilizes the optical principle automatic switch, but water dispenser is loaded onto behind this controller not only saves energy 20-40%, can prolong the service life of water dispenser simultaneously.This controller is reasonable in design, circuit simple, stable performance.

The technical scheme that the utility model adopted is: the light-operated controller that is used for water dispenser, it comprises sample circuit, its output connects CMOS integrated circuit NAND gate control circuit, the output of CMOS integrated circuit NAND gate control circuit connects governor circuit, and governor circuit inserts the input power supply simultaneously and output supply voltage is provided.

Sample circuit described in the utility model mainly contains photo resistance RL, it and another resistance R ₄Form sample circuit.

Described CMOS integrated circuit NAND gate control circuit mainly contains CMOS integrated circuit NAND gate I, II, the pin 1 of NAND gate I, pin 2 are connected with photo resistance RL, pin 3 connects pin 5, the pin 6 of NAND gate II, and the pin 4 of NAND gate II is connected with the trigger electrode of controllable silicon VS in the governor circuit.

Described governor circuit mainly contains controllable silicon VS and relay R J, and output voltage is through two contact R J of relay ₁And RJ ₂After add to the water dispenser heater.

The beneficial effects of the utility model are: add this light-operated controller in the circuit of common water dispenser after, make when water dispenser is handled official business by day, or night controller self-opening power supply when light-illuminating is arranged, the water dispenser operate as normal, and when the curtain of night came or ceases lamp and sleep peacefully, controller was cut off the electricity supply automatically, shortened the time of water dispenser work greatly, generally can shorten more than 9-13 hour, increase the service life of water dispenser, fractional energy savings reaches 20-40%.In addition, this controller is reasonable in design, circuit simple, stable performance.

Description of drawings

Fig. 2 is the electrical schematic diagram of the utility model embodiment.

The specific embodiment

As shown in the figure, present embodiment is made up of sample circuit 1, CMOS integrated circuit NAND gate control circuit 2 and governor circuit 3.

Sample circuit 1 mainly is a photo resistance RL, with resistance R ₄Form bleeder circuit, provide sampled signal to CMOS integrated circuit NAND gate control circuit 2, this control circuit mainly contains CMOS integrated circuit NAND gate CD4011, comprises NAND gate I and II, and input pin 1 and the pin 2 of NAND gate I meet photo resistance RL and R ₄Dividing point, output pin 3 connects input pin 5 and the pin 6 of NAND gate II, the output pin 4 of NAND gate II is through isolation resistance R ₇Connect the trigger electrode of controllable silicon VS, governor circuit 3 mainly contains controllable silicon VS, relay R J and auxiliary circuit is formed, and the electric main of 220V inserts governor circuit, via diode VD ₄-VD ₇The rectification circuit of forming provides direct current to sample circuit 1 and CMOS integrated circuit NAND gate control circuit 2, and in check 220V ac output voltage is by two contact R J of relay simultaneously ₁And RJ ₂Add to the water dispenser heater.

Operation principle of the present utility model is: the photo resistance RL of sample circuit 1 is low-resistance when illumination, pin 1 and the pin 2 of the NAND gate I of CMOS integrated circuit NAND gate control circuit 2 are high potential, and the pin 5 of pin 3 and NAND gate II and pin 6 are electronegative potential, at this moment the pin 4 of NAND gate II is exported high potentials, through isolation resistance R ₇Trigger controllable silicon VS conducting, relay R J work, contact R J ₁, RJ ₂Adhesive work, output AC220V voltage.

When sample circuit lost illumination, photo resistance RL was high resistant, and the pin 1 of NAND gate I and pin 2 are electronegative potential, at this moment the pin 5 of the pin 3 of NAND gate I and NAND gate II and pin 6 are high potential, this moment, the pin 4 of NAND gate II was output as electronegative potential, and controllable silicon VS blocks not conducting, and relay R J does not work.The periodic duty that goes round and begins again reaches control, energy-conservation purpose.
