Preferably, in the present embodiment, A pole winding is two pole windings, and B pole winding is four pole windings, and certainly, A pole winding also can be four pole windings, and B pole winding can be also ends of the earth winding, and at this, the present invention does not do concrete restriction.
Optionally, two pole windings comprise the first winding and the second winding, and four pole windings comprise the first winding, the second winding, the tertiary winding and the 4th winding, the first end points and the first winding switching, the second end points and the second winding switching, the 3rd end points and the 4th winding switching.
When the first end points and the second end points switch on power, electric current is only by the first winding and the second winding, when electric current is only by the first winding and the second winding, compressor is with the first rotational speed, and when the first end points is connected with the 3rd end points, electric current is by four windings, when electric current is by four windings, compressor is with the second rotational speed, and wherein, the first rotating speed is greater than the second rotating speed.
When compressor passes through two pole windings with the first rotational speed, the motor in this compressor can be regarded as two-pole machine, and when compressor passes through four pole windings with the second rotational speed, the motor in this compressor can be regarded as quadrupole motor; Wherein, the rotation that motor is compressor provides power.The group number that coil distributes in motor is called pole level, and the pole of motor is all paired appearance, if only have a pair pole in motor, then motor is bipolar machine; If have two in motor to pole, then motor is quadrupole motor, if having three in motor to pole, then motor is 6-pole motor, by that analogy.Wherein, the rotating speed of two-pole machine is about 3000 revs/min, and the rotating speed of quadrupole motor is about 1500 revs/min.Certainly, the compressor of refrigerator also can comprise four pole windings and ends of the earth winding, and at this, for the number of poles of motor, the present invention does not do concrete restriction.Preferably, when compressor is with the first rotational speed, the motor in this compressor can be regarded as two-pole machine, and when compressor is with the second rotational speed, the motor in this compressor can be regarded as quadrupole motor.
In the start-up course of compressor, be two pole windings with A pole winding, B pole winding is four pole windings is that example is described, controller first can control the first switch and close, two pole windings are switched on power, electric current is by two pole windings, thus drive compressor with larger rotational speed, after compressor operating to certain hour section, controller can control the first switch and disconnect, and closed second switch, makes four pole windings switch on power simultaneously, electric current by four pole windings, thus drives compressor with less rotational speed.Certainly, in the start-up course of compressor, controller also first can control second switch and close, make compressor first with less rotational speed, when after compressor operating to certain hour, controller can control second switch and disconnect, and closed first switch, makes compressor with larger rotational speed simultaneously.At this, in the start-up course of compressor, compressor is first still first with less rotational speed with larger rotational speed, and the present invention does not do any restriction.Preferably, consider in compressor start process, compressor needs to reclaim lubricant oil, compressor damage is caused to prevent friction in compressor operating process, therefore, compressor can first with larger rotational speed because only with larger rotational speed time, just can produce larger pressure, make compressor to reclaim lubricant oil.
After refrigerator starts, same is two pole windings with A pole winding, B pole winding is four pole windings is that example is described, when ambient temperature is in the condition of high temperature, controller controls the first switch and closes, and makes compressor with higher rotational speed, drives compressor operating, thus the output quantity of the refrigeration agent produced is more, meet the demand that needs refrigeration agent output quantity is more when refrigerator is in the condition of high temperature.After compressor operating a period of time, if ambient temperature is in low-temperature condition, then controller controls the first switch disconnection, and control second switch simultaneously and close, compressor just can with lower rotational speed, drive compressor operating, now, the output quantity of the refrigeration agent that compressor produces is less, meets the demand that needs refrigeration agent output quantity is less when refrigerator is in low-temperature condition, meanwhile, the higher demand of compressor efficiency can also be met.Like this, in this refrigerator, controller just can control electric current through different windings, thus drive compressor with different rotational speed, as invariable frequency compressor of the prior art, the rotating speed that fixing need not be only had, therefore, in this application, by controller for compressor different rotating speeds is provided time, power consumpiton is less, and effect is higher, can solve in the process run at invariable frequency compressor in prior art, the problem that the fit of compressor effect and ambient temperature is not high.
Optionally, in the present embodiment, the rotating speed of compressor can also be regulated according to other modes, make compressor with different rotational speed, thus meet the demand of compressor different load amount.Such as, the rotating speed of compressor can be regulated according to operation ratio.Wherein, operation ratio refers to the ratio that the boot running time of compressor accounts for cumulative time (summation of compressor available machine time and dead time).Detailed process is: after refrigerator starts, compressor can run with a default frequency according to actual needs, when after the compressor operating regular hour, compressor is out of service, namely compressor starts enters outage state, when compressor runs again, can according to the operation ratio calculating compressor dead time of the working time of compressor and compressor, if the operation ratio of compressor is less than the arbitrary value in a certain preset range, then need the operation frequency reducing compressor, reduce the rotating speed of compressor, thus reduce the refrigerating capacity of compressor, meet when the less demand of refrigerator refrigerant output quantity, simultaneously, the demand that compressor efficiency is higher can also be met.If the operation ratio of compressor is greater than the arbitrary value in a certain preset range, then illustrate that the output quantity of the refrigeration agent of now compressor is not enough, need the operation frequency improving compressor, improve the rotating speed of compressor, thus improve the refrigerating capacity of compressor, meet when the more demand of refrigerator refrigerant output quantity.Preferably, the preset range of operation ratio is 70%-80%, so, compressor is in the process run, the power consumpiton of compressor is less, effect is higher, can solve in the process run at invariable frequency compressor in prior art equally, the problem that the fit of compressor effect and ambient temperature is not high.
