The specific embodiment
Below, the refrigerator to an embodiment of the invention describes with reference to the accompanying drawings.
(the 1st embodiment)
According to Fig. 1 and Fig. 2 the refrigerator of the 1st embodiment of the present invention is described.
The refrigerator 10 of present embodiment has the ferraris motor 14 that is used for drive compression machine 12, by control device 15 its rotations of control.This induction conductivity 14 has main winding and auxiliary winding, and has auxiliary coil termination A, main winding terminal B and common terminal C.
(1) structure of control device 15
According to Fig. 1 the structure of the control device 15 that is used for driven induction motor 14 is described.
Control device 15 has control part 16 and inverter part 18.
The output of inverter circuit 32 is applied in auxiliary coil termination A, main winding terminal B and the common terminal C to induction conductivity 14.At this moment, the state of a control that decides compressor 12 of magnitude of voltage and the frequency by this driving voltage.
(2) state of a control
Then, the state of a control to above-mentioned control device 15 describes.
When the temperature inside the box of case inner sensor 22 detections rises than fiducial temperature, then be necessary to make compressor 12 to move and cool off.Therefore, the power supply that applies from 16 pairs of inverter part 18 of control part becomes connection.When power connection, the control signal of the control model that is predetermined from the output of the memory of electromotor control circuit 28, inverter circuit 32 is according to the control signal driven induction motor 14 of this control model.
This control model like that, is made of the 1st pattern and the 2nd pattern shown in the figure of Fig. 2.Be meant particularly, the 1st pattern is, during from power connection to the moment t1 that is predetermined, with the magnitude of voltage 100[V identical with source power supply 20] driving voltage and frequency 50[Hz] drive, the 2nd pattern is, through making driving voltage reduce to 80[V after the t1 constantly] and frequency reduce to 40[Hz] move
(3) effect
According to present embodiment, owing to, therefore can carry out energy-saving run through t1 driving voltage and frequency decline afterwards constantly.
In addition, by only being connected inverter part 18 between in the past control part 16 and the induction conductivity 14, thereby even induction conductivity in the past 14 also can carry out energy-saving run.
(the 2nd embodiment)
Then, according to Fig. 3 and Fig. 4 the refrigerator 10 of the 2nd embodiment is described.The difference of present embodiment and the 1st embodiment is that electromotor control circuit 28A does not store control model, applies the control signal 34 from control part 16 on the contrary, and controls induction conductivities 14 by this control signal 34.
Even present embodiment, also by only being connected inverter part 18 between in the past control part 16 and the induction conductivity 14, thereby even induction conductivity in the past 14 also can carry out energy-saving run.
Below, each control method of the control device 15A of the 2nd embodiment is described successively.
(1) the 1st control method
The 1st control method is, detect the temperature inside the box by case inner sensor 22, under the situation about having turned cold in the case, reduces the order of rotating speed based on 34 pairs of inverter part 18 of control signal.
In addition, become in the case under the following situation of fiducial temperature, output is ceased and desisted order.And then, detected under the situation of the temperature inside the box rising, because be necessary to reduce peremptorily the temperature inside the box, therefore send the order that improves rotating speed.
According to the 1st control method, because control part 16 can detect the load change of refrigerator 10 by case inner sensor 22, therefore control the rotating speed of compressor 12 by corresponding its variations in temperature, can realize more effectively energy-saving run.
(2) the 2nd control methods
The 2nd control method is, detect the temperature inside the box by case inner sensor 22, under the situation about having turned cold in the case, inverter part 18 reduced the order of voltage.At this moment, the main winding and the auxiliary winding of induction conductivity 14 are adjusted voltage respectively.In addition, detected under the situation of the temperature inside the box rising,, therefore, carried out driving voltage is risen to the order that supply voltage moves because be necessary to reduce peremptorily the temperature inside the box.
According to the 2nd control method, because control part 16 can detect the load change of refrigerator 10 by case inner sensor 22, therefore control the driving voltage of compressor 12 by corresponding its variations in temperature, can realize more effectively energy-saving run.
(3) the 3rd control methods
The phase difference that puts on the voltage of the main winding of induction conductivity 14 and auxiliary winding is generally about 90 degree, in the 3rd control method, carries out the order that this phase difference is adjusted to the high efficiency position corresponding with motor characteristic.
According to the 3rd control method, phase place is adjusted to the position of the peak efficiency corresponding with motor characteristic, can carry out energy-saving run.
(4) the 4th control methods
In the 4th control method, electromotor control circuit 28A carries out PWM (pulse width modulation, Pulse Width Modulation) control for inverter circuit 32.But in PWM control, though can carry out finer control when improving the PWM frequency, correspondingly, the switch number of times increases, and switching losses also increases.On the other hand, if can suppress switching losses just reduce the PWM frequency.
Therefore, thus control part 16 respective motor characteristics or freeze cycle export optimum pwm signal and control electromotor control circuit 28, and carry out energy-saving run.
(5) the 5th control methods
In the 5th control method, when electromotor control circuit 28A basis changed motor frequency or driving voltage from the order of control part 16, its rate of change was variable.
According to the 5th control method, can the respective motor characteristic and to carrying out inching with respect to the tracking that changes.
(6) the 6th control methods
In the 6th control method, during by inverter part 18 driven induction motors 14, its start-up mode is variable.For example as shown in Figure 4, little by little increase frequency and driving voltage is controlled, adjust its each gradient A1, A2 and initial value Fb, the Vb of each.
In addition, not only can carry out such a Linear Control, also can be corresponding to various patterns, also can the suction of compressor 12 with the change pattern such as blow out when having pressure differential.
According to the 6th control method, can prevent the failure that starts by carrying out inching.
(modification)
The invention is not restricted to the respective embodiments described above, can in not breaking away from this aim, carry out various changes.
