Description of drawings
Above-mentioned and/or others of the present invention and advantage will become clear and be easier to from the following explanation of in conjunction with the accompanying drawings exemplary embodiments and understand, wherein:
Fig. 1 is the control calcspar of refrigerator according to an embodiment of the invention; And
Fig. 2 is for showing the control flow chart of the method be used to control refrigerator according to an embodiment of the invention.
The specific embodiment
Now will be in detail with reference to embodiments of the invention, example of the present invention illustrates in the accompanying drawings, wherein identical reference symbol is represented components identical among in the whole text.By embodiment being described below with explanation the present invention with reference to being shown in.
Fig. 1 is the control calcspar of refrigerator according to an embodiment of the invention.
As shown in fig. 1, refrigerator 1 comprise the motor 20 of compressor 10, drive compression machine 10, to the motor driver 30 of motor 20 supply electric power and the controller 40 of control motor driver 30.
The compressor 10 of refrigerator 1 is with high temperature and high pressure compressed refrigerant.Compressor 10 comprises the piston that is connected to motor 20, and refrigerant by piston according to the linear movement repeatedly of the rotation of motor 20 and compressed repeatedly and expand.
Motor 20 can be set to brushless direct-current (DC) motor.Motor 20 utilizes from the power driven compressor 10 of motor driver 30 supplies.The speed of motor 20 is by 30 decisions of controller 40 and motor driver, and can be according to the surrounding environment change of refrigerator.
For example, the speed of motor 20 changes according to the environment temperature of refrigerator, Current Temperatures and preset temperature in the refrigerator.In addition, the residual compression in the motor 20 can also cause the velocity variations of motor.For example, temperature when the environment temperature of refrigerator in the higher relatively or refrigerator and the difference between the preset temperature be not in predetermined permissible range the time, can be in order to increase cooling velocity with high-speed driving compressor 10, otherwise, temperature when the environment temperature of refrigerator in the relatively low or refrigerator and the difference between the design temperature can be with driven at low speed compressors 10 in order suitably to keep cooling velocity in predetermined permissible range the time.
Simultaneously, when the remarkable refrigerator higher or that close for a long time of the temperature in the refrigerator was activated, refrigerator can consume a large amount of electric power so that the temperature in the refrigerator reduces.When being driven under the refrigerant cycles of compressor 10 in this overload, the pressure differential between delivery unit of compressor 10 (outlet) and the pump unit (inlet) significantly increases, thereby causes the high torque (HT) load of the motor 20 of drive compression machine 10.This high torque (HT) load meeting causes the speed of motor 20 to increase.
Motor driver 30 is supplied the electric power that is used for drive motor 20 to motor 20, and controller 40 controls drive the ON/OFF ratios.Motor driver 30 comprises converter (converter) (not shown) and makes the transverter that is converted into the AC power of input motor 20 from the dc power of converter output.
Converter is converted to dc power with AC power, and dc power is changed according to the given control signal of transverter.
Transverter comprises a plurality of switch elements, and each switch element is started repeatedly/closes according to pulsewidth modulation (PWM) control signal of slave controller 40 outputs.Drive the ratio that the ON/OFF ratio is understood that the break period of connection cycle of switch element and switch element.That is, when driving the increase of ON/OFF ratio, bigger power is supplied to motor 20, thereby increases the speed of motor 20.Reference value for the cycle of connection can change, as long as satisfy this relation between the speed that drives ON/OFF ratio and motor 20.
Therefore, drive the duty ratio that the ON/OFF ratio can be replaced by the switch element of transverter according to an embodiment of the invention, described duty ratio is represented the connection cycle of switch element and the ratio of an ON/OFF circulation.The power that is fed to motor 20 increases along with the increase of the duty ratio of switch element, thereby increases the speed of motor 20.
Controller 40 detects the state of refrigerator 1 and the speed of motor 20, with speed, and will output to motor driver 30 corresponding to the control signal of given speed command according to the state of refrigerator 1 and the speed of motor 20 according to the state of refrigerator 1 control motor 20.The control signal of slave controller 40 output comprises the pwm control signal of the switch element that is used to control transverter.
As mentioned above, when refrigerant cycles is activated and therefore makes the load torque of motor 20 to increase, should be higher than the voltage of rated voltage under overload to motor 20 supplies.Therefore, controller 40 can be exported the control signal corresponding to the command speed of the speed that is higher than motor 20, and wherein said motor is driven with rated voltage.Hereinafter, the speed that is used to overcome the motor 20 of load torque is known as first command speed.
When controller 40 will output to motor driver 30 corresponding to the control signal of first command speed, motor driver 30 was changed the switch element of transverter.Yet, even increase to maximum when driving the ON/OFF ratio, in other words, the duty ratio of switch element is 100%, when the speed of motor 20 did not reach first command speed owing to load torque yet, controller 40 can be exported the control signal corresponding to second command speed that is lower than first command speed.As a result, can reduce, and can prevent owing to excessive drive motor 20 breaks down from the noise of refrigerator generation.
After corresponding to the output of the control signal of second command speed, controller 40 determines whether the driving ON/OFF ratio of motor drivers 30 can remain on the low numerical value of comparing with given referenced drive ON/OFF ratio and reach the given reference cycle.In more detail, remain on given referenced drive ON/OFF ratio when driving the ON/OFF ratio, for example, be lower than 80% but not 100% when reaching described reference cycle, meaning can be with second command speed drive motor 20 fully.
When reaching than long cycle in reference cycle with the second command speed drive motor 20 that is lower than first command speed, controller 40 can determine that the load torque of motor 20 reduces and exports control signal corresponding to first command speed.
When even the speed of motor 20 is reduced to second command speed and electric power is supplied to motor 20 fully, when the speed of motor 20 did not reach second command speed yet, controller 40 can be exported corresponding to the control signal of the speed that is lower than second command speed and repeat said process.
According to prior art, output is corresponding to the control signal of second command speed that is lower than first command speed, and the speed of motor 20 remains on second command speed, the result, and the cooling velocity of refrigerator can reduce.Yet according to the present invention, the speed of motor 20 can be according to the recovering state of motor 20 to first command speed.
When the speed of motor 20 reached first command speed by the control signal corresponding to first command speed, controller 40 can increase referenced drive ON/OFF ratio or reduce the reference cycle.For the variation of this drive condition of motor 20 is to produce noise in order to prevent when the velocity variations of motor 20, and drive motor 20 stably when changing repeatedly for the speed at motor 20.
That is, the speed that has reached the motor 20 of first command speed can be reduced to second command speed.For fear of the variation repeatedly of electromotor velocity and drive motor 20 stably, when the speed of motor 20 when first command speed is reduced to second command speed, referenced drive ON/OFF ratio is increased to 90% from 80%.In addition, can make the speed of motor 20 promptly change to first command speed by the reference cycle that reduces second command speed from second command speed.
When the speed of motor 20 did not reach first command speed, controller 40 can make referenced drive ON/OFF ratio be reduced to 70% or increase the reference cycle from 80%.When referenced drive ON/OFF ratio is set too highly relatively or the residual negative set torque of motor when higher relatively, even output to motor driver corresponding to the control signal of first command speed, the speed of motor 20 does not reach first command speed yet.Therefore, controller 40 can reduce referenced drive ON/OFF ratio, causes the speed of motor 20 to remain at the state of second command speed with mitigation, perhaps increases the reference cycle till the load torque of motor 20 significantly reduces.
This extra control of controller 40 can prevent that motor 20 is subjected to unusual driving between first command speed and second command speed, and can reduce the noise and the vibration that produce when the velocity variations of motor 20.
Therefore when having load torque in the motor 20, and be lower than normal voltage and during with higher relatively speed drive motor 20, controller 40 is activated when the primary power voltage of input refrigerator.
According to function aspects, controller 40 is determined the state of refrigerator and is controlled motor driver 30 according to embodiments of the invention.Yet, the overall status and the control motor driver 30 that can provide two controllers to come to control by the temperature that detects refrigerator respectively refrigerator, and motor 20 can be controlled by the connection between two controllers.
Fig. 2 is for showing the control flow chart of the method be used to control refrigerator according to an embodiment of the invention.The method that is used to control refrigerator now with reference to Fig. 2 explanation.
When refrigerator is in the state of overload or supply voltage when relatively low, be output (S10) corresponding to the control signal of first command speed.At this moment, first command speed is higher than the normal speed of motor 20.After the given cycle, determine whether the driving ON/OFF ratio of motor driver 30 increases to maximum (S20).
When driving ON/OFF ratio does not increase to maximum, can be understood as with the first command speed drive motor 20.
Be determined when increasing to maximum when driving the ON/OFF ratio, determine then whether the speed of motor 20 reaches first command speed (S30).Although increase to maximum when driving the ON/OFF ratio, when the speed of motor 20 does not reach first command speed yet, controller 40 can output corresponding to the control signal of second command speed that is lower than first command speed, produce noise and vibrations and reduce the load (S40) of motor 20 from motor 20 preventing.
Subsequently, whether the driving ON/OFF ratio of determining motor driver 30 remains on referenced drive ON/OFF ratio (S50) and reaches the reference cycle.When described driving ON/OFF ratio remains on referenced drive ON/OFF ratio when reaching the reference cycle, controller 40 is exported once more corresponding to the control signal of first command speed (S60).This means that motor 20 is in the state that can reach first command speed.
After the control signal of output corresponding to first command speed, controller 40 determines whether the speed of motor 20 reaches first command speed (S70).
When the speed of determining motor 20 does not reach first command speed, driving the ON/OFF ratio reduces, so that the speed of motor 20 can reach first command speed at an easy rate, perhaps the reference cycle of second command speed is increased to the load torque (S80) that can significantly reduce motor 20.
Yet, when the speed of motor 20 reaches first command speed, driving the ON/OFF ratio increases, to prevent motor repetitive operation between first command speed and second command speed, perhaps when the load torque of determining motor 20 significantly reduced, the reference cycle of second command speed can reduce (S90).
As mentioned above, even according to refrigerator of the present invention and the method that is used to control described refrigerator also can be stablized under the condition of overload or low-voltage and drive compression machine easily.
Although illustrated and illustrated a plurality of exemplary embodiments of the present invention, yet those of ordinary skills will be understood that, can do change to these embodiment under the prerequisite that does not depart from principle of the present invention and essence, scope of the present invention is limited by claim of enclosing and equivalents thereof.
