Abstract
The utility model relates to a controller of a drinking water machine, which comprises a controller. The controller comprises a refrigeration circuit, a heating circuit and other functional circuit. The part between the controller and the external power supply circuit is provided with an optical control circuit which controls the circulation and cutoff of the relay, thus controlling the working state of the drinking water machine. When the illuminance is high, the contact of the relay is turned on and the drinking water machine is on the wording state. When the illuminance is low, the relay is cut off and the drinking water machine stops working. The utility model has a simple structure and convenient usage, thus being used at home, office and other public places.
Description
The utility model is a kind of water dispenser.
Water dispenser of the prior art in use needs user's manually-operated just can cut off the electricity supply, often when the night rest, water dispenser is also worked always, to cause the waste electric energy like this, the service life of reactive power consumption machine, and the influence of the running noise of water dispenser is had a rest.
The purpose of this utility model provides a kind of water dispenser that can cut off the electricity supply automatically when illuminance is not enough.
The purpose of this utility model is achieved in that it comprises control section, described control section comprises refrigeration circuit, heater circuit and other functional circuit, described control section and outside light-operated circuit also is set between the supply line, the transformer of this light-operated circuit inserts power supply, output voltage is given between the resistance of light-operated circuit and the ground and is made the work power supply after the bridge rectifier rectification that the output voltage of transformer is formed via diode, amplifier and resistance and diode constituent ratio are than amplifying circuit, the operating voltage of this amplifying circuit provides after by resistance and diode and capacitance voltage stabilizing filtering, the resistance of photo resistance changes with illuminance, detect usefulness as illuminance, the output of amplifier connects switch triode through resistance, by the conducting of triode and the conducting that ends to come control relay with end.
The advantage of the utility model contrast prior art is: because be provided with light-operated circuit, make the user can not cut off the working power of water dispenser automatically during water in night, thus can energy savings, reduce noise, and the service life of corresponding prolongation water dispenser.
Fig. 1 is a control circuit block diagram of the present utility model;
Fig. 2 is the utility model light-operated circuit schematic diagram.
The utility model is described in further detail below in conjunction with drawings and Examples:
Referring to accompanying drawing 1,2, light-operated circuit is located between control section and the outer supply line, the transformer B1 of light-operated circuit inserts power supply, the transformer output voltage is exported to light-operated circuit and is made the work power supply after the bridge rectifier rectification, amplifier A0 and resistance R 2, R3, R4, R6, R7 and diode D6 constituent ratio are than amplifying circuit, the operating voltage of this amplifying circuit provides after by resistance R 1 and diode D5 and capacitor C 1 voltage regulation filtering, R5 is photo resistance, its resistance changes with illuminance, as the illuminance testing circuit, the output of amplifier A0 meets switch triode T1 through resistance R 8.During use, connect K switch 1, when the illuminance of water dispenser environment for use increased, the resistance of photo resistance R5 diminished, when illuminance greater than 20 lux-hours, the resistance of photo resistance R5 is less than the resistance of resistance R 3, the voltage that A is ordered is lower than the B point, amplifier A0 output HIGH voltage, and triode T1 ends, contact b, the c of relay J 1 connects, and water dispenser enters duty.When the illuminance of water dispenser environment for use reduces, it is big that the resistance of photo resistance R5 becomes, when illuminance less than 20 lux-hours, the resistance of photo resistance R5 is greater than the resistance of resistance R 3, and the voltage that A is ordered is higher than the B point, amplifier A0 output LOW voltage, triode T1 conducting, contact a, the b of relay J 1 connects, and water dispenser has only light-operated circuit work, enters the low power consuming duty.Diode D6, resistance R 6 forms the feedback circuit of amplifiers, and when the current potential of order as A was higher than B point, amplifier A0 upset was low-voltage output, and diode D6 conducting makes the reduction of B point current potential, guarantees that it is that low-voltage is exported that amplifier A0 reliably overturns; When the current potential of ordering as B was higher than the A point, amplifier A0 upset was high voltage output, and diode D6 ends, and B point current potential is raise, and was that high voltage is exported to guarantee that amplifier A0 reliably overturns.Realization prevents that the misoperation phenomenon from appearring in amplifying circuit when upset.
When the user need make water dispenser in running order when illuminance breaks down less than 20 lux-hours and light-operated circuit, K switch 1 can be disconnected, light-operated circuit does not quit work because of there being power supply, and relay contact b, c connect, and the water dispenser duty no longer is subjected to the influence of ambient light illumination.
Claims (1)
