Abstract
The utility model relates to a novel air conditioner protector, and an NE555, a relay J[1] and a temperature-controlling switch can form the controlling circuit for controlling the on-off of a compressor. The circuit design is simple and reliable and can prevent the damages to the compressor of the air conditioner caused by network voltage fluctuation, sudden power failure, sudden starting, reciprocating switching the temperature controller, etc. The utility model can also separate strong and weak current and assure the contact points of the temperature-controlling switch can not be burnt out, and the utility model has low cost, convenient installation and complete function.
Description
The utility model belongs to the application of electronic technology field.
Along with the development of producing, the raising of living standards of the people, domestic air conditioning steps into common people house, uses more and more general.But the holding circuit of commercially available now various domestic air conditioners is very simple, only depends on compressor section to have an electrothermal relay to protect, and its work is not really reliable, thus under following situation (as the plugs and sockets loose contact; Mains supply is too low or too high for voltage; Electrical network cuts off the power supply suddenly, does not cut off the electricity supply immediately, and electric network source is connected once more in three minutes; Under the duty, temperature controller fiddles with; After stopping refrigeration, starting once more in three minutes etc.) phenomenon of compressor all might appear burning out.In addition, because the temperature detect switch (TDS) of all window air conditioners is all directly by the break-make of big Current Control compressor, the frequent movement of temperature detect switch (TDS) makes the electric arc of big electric current generation burn out the contact over a long time, causes not freeze or compressor is worked always and be cannot stop.
The purpose of this utility model just provides a kind of multi-functional air conditioner protector, makes when above various fortuitous event occurring, guarantees that all air-conditioner normally uses, and does not cause the damage to compressor.By the retrieval and the market survey of available data among the adversary, do not seen multi-functional air conditioner protector like this as yet.
The purpose of this utility model is achieved in that air conditioner protector is connected between the temperature controller and compressor of air-conditioner that the controllable silicon in the air conditioner protector is connected on the electric power incoming line, can control the break-make of air-conditioner electric current.When power supply rigidly connects when logical, when indoor temperature was cooled to fixed temperature, the testing circuit of air conditioner protector was measured and is worked, and the controllable silicon of electric power incoming line is disconnected, and through about three minutes time-delays controllable silicon was connected, and guaranteed the normal use of air-conditioner.
Adopt such scheme, can make strong and weak electricity separately, when mains fluctuations or temperature detect switch (TDS) frequently change, all earlier make the compressor delayed firing, avoid compressor damage by air conditioner protector.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is detailed electric schematic circuit, wherein IC

1With the control circuit of temperature detect switch (TDS) composition, form mu balanced circuit by 7812 to the compressor break-make.The whole connection of each electronic component seen Fig. 1.
Fig. 2 is the schematic diagram that this air conditioner protector connects with window air conditioner.KB is this air conditioner protector, above target 1,2,3,4,5 be corresponding points among Fig. 1.Wherein C is a compressor, and W is a blower fan, and t is a temperature detect switch (TDS), and H is an electrothermal relay.A, B, C, D, E are each grades of air-conditioner switch.A closes, and B is a high wind, and C is cold by force, and D is weak cold, and E is weak wind.Temperature detect switch (TDS) t and the former line of electrothermal relay are disconnected; 1 of air conditioner protector terminates at the leading-out terminal of temperature detect switch (TDS) t, and 2 terminate to the end of incoming cables of electrothermal relay H, and 4 terminate to electric power incoming line live wire end; 3 terminate to the end of incoming cables of temperature controller switch, and 5 terminate on the zero line of logical compressor and fan power line.LED
1Be light emitting diode, go bail for and protect indicator lamp, bright when shielding; LED
2Be the green light diode, make the refrigeration indicator lamp, bright when compressor starts.
When electric network source rigidly connects when logical, transformer has voltage output, and 3 pin of NE555 are high level, J
1Dead electricity, controllable silicon BCR is obstructed, and compressor does not have electricity does not work LED
1Glow, the expression air-conditioner is protected.Behind the delay circuit to 3 minute, J
1Must be electric, LED
1Go out, BCR is logical, and compressor could be worked, at this moment J
2Must be electric, LED
2Green light is bright, and the indication compressor is in work.When being cooled to fixed temperature, temperature controller disconnects, and BCR is disconnected, J
2Dead electricity, LED
2The refrigeration green light goes out, and 3 pin of NE555 become high level, J because of 5 pin level raise
1Dead electricity, LED
1The protection red light is bright, delay circuit work, J after 3 minutes
1Just electricity can be arranged, so even the temperature controller that at this moment fiddles with is also inoperative, BCR is all obstructed, compressor is protected.After also promptly stopping compressor operating, can keep not started suddenly in three minutes.
When line voltage was too high or too low, BG made 3 pin places become high level, J by 2 pin that Vb and Vc pass to NE555
1Dead electricity, BCR is disconnected, and compressor is protected and do not work LED
1The protection red light is bright.
This protector is the control electric current (milliampere level) of BCR by the electric current of temperature detect switch (TDS); the big electric current of control compressor break-make (ampere level) is served as by contactless controllable silicon BCR; Rv is the thermistor of protection BCR, thereby has stopped electric arc that the temperature detect switch (TDS) contact produces because of the big electric current of break-make and cause the situation that burns out.The C of protector

2, J
2The also available AC relay of part substitutes, but price wants expensive.
The utility model circuit design is simple and reliable, and strong, weak electricity is control separately, installs simple and easy.Cheap, but play the effect of protecting air-conditioning effectively.Through the use in last year in whole summer, may cause the various situations of damage all to avoid to compressor to above-mentioned.This protector is applicable to refrigerator, colour TV, advanced audio too, and promotional value is arranged very much.
