Technique effect of the present utility model is: this utility model utilizes integrated chip to achieve the generation of artificial negative oxygen ion, thus obtain the automatic deodorizing function of electric refrigerator fresh-keeping chamber and the preservation of food, circuit design advantages of simple, reliable and with low cost, form owing to adopting simple and reliable hardware circuit, not only cheap, and easy to use, therefore can be used as the accessory product of conventional refrigerator based on this electronic deodorizer, application prospect is better.
Accompanying drawing explanation
Fig. 1 is functional-block diagram of the present utility model.
Fig. 2 is circuit diagram of the present utility model.
In the drawings, 1, current rectifying and wave filtering circuit 2, light-operated circuit 3, automatic time delay control circuit 4, oscillating circuit 5, negative oxygen ion produce circuit.
Detailed description of the invention
Composition graphs 1,2 illustrates this utility model, described current rectifying and wave filtering circuit 1, light-operated circuit 2, automatic time delay control circuit 3, oscillating circuit 4, negative oxygen ion produce circuit 5 and connect successively, described light-operated circuit 2 is made up of refrigerator lighting lamp and phototriode, and described phototriode is just to refrigerator lighting lamp.
Described negative oxygen ion circuit is made up of booster transformer, high voltage silicon rectifier stack, protective resistance and spray point.
Described protective resistance R6=3.9M Ω.
Spacing between needle point in described spray point is 1mm.
Described automatic time delay control circuit adopts μ A555 chip.
When user open fridge freshness retaining room pick and place food time, gate controlled switch SB action, illuminating lamp L lights, phototriode T
1light conducting, the then rapid step-down of current potential of the 2nd foot of chip μ A555, the current potential of the 3rd foot of outfan uprises, and triggers bidirectional thyristor T
2conducting, booster transformer BT starts working, and spray point two ends obtain high pressure, form the ozone of a large amount of negative oxygen ions and some (not exceeding standard) and spread in fridge freshness retaining room, thus playing effect of sterilizing, deodorizing and fresh keeping, while negative oxygen ion produces, 220V alternating current is by resistance R
2to electric capacity C
3charging, as electric capacity C
3voltage when reaching 2/3 of chip operating voltage, then the rapid step-down of current potential of the 3rd foot of chip μ A555, turns off bidirectional thyristor T
2, negative oxygen ion generator quits work, electric capacity C
3voltage discharged by chip internal discharge tube, so circulate, according to the technical parameter indicated in Fig. 2, can show that user often opens the door of a refrigerator, negative oxygen ion produce about 5 minutes circuit 5 working times, as bidirectional thyristor T
2after conducting, 220V alternating current controls IGCT T by forming unidirectional pulsating current after pressure limiting rectifying and wave-filtering
3break-make, produce oscillator signal, produce high pressure and discharge through spray point after boosting, produce negative oxygen ion, as change resistance R
2size, the negative oxygen ion generator working time can be changed, can by resistance R in concrete enforcement
2substitute with variable potentiometer.
In order to ensure the safety of circuit, protective resistance R6=3.9M Ω being set at spray point high-pressure side, in debug process, rationally placing phototriode T
1, require to aim at illuminating lamp L, the gap of spray point will be adjusted accurately, and make spray point center point sharp-pointed as far as possible, discharge with convenient spray point, stabilivolt D
wtype selecting number is 2CW11 or 2CW21H, IGCT T
2and T
3parameter is 1A/400V, and high voltage silicon rectifier stack (16kV) type selecting number is 2DGL.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from this utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that this utility model claims determine.
