Embodiment
Below, being described with reference to the accompanying drawings the preferred embodiments of the present invention, the example is shown in the drawings.
Fig. 1 is the planimetric map according to washing machine running gear of the present invention.
As shown in Figure 1, washing machine running gear according to the present invention comprises: power unit 1, input AC electricity (AC power); Conversion portion 2 will be converted to direct current by the alternating current of power unit input; Smooth unit 3, the direct current that conversion portion 2 is changed carries out smoothly; Inverter 4 is when conversion the is smoothed time generation motor operation signal that be galvanic electric power; And motor 5, by the operation power of inverter input.
Also comprise: control section 6 produces the switching signal of control inverter 4 electric power, and is input in the inverter 4; Storer 7 is wherein stored the required information of control section 6 operations.As distinguishing characteristics of the present invention, with at least two kinds of reference signals of form set of look-up table, to call suitable reference signal according to the running status of motor.For example, wherein a kind of reference signal is first look-up table, be used for the two-phase operation of motor, and another kind of reference signal is a second look-up table, is used for the three-phase operation of motor.Reference signal has been mentioned in the front, thereby it forms the required switching signal of inverter operation by comparing with carrier signal.And the pwm signal that forms by inverter is input to the run signal that is used as motor in the motor 5.
Based on the running gear that is same as proposed washing machine, the operation method of washing machine of the present invention is made brief description.
At first, the various strokes that carry out in the washing machine comprise: the stroke that needs the motor rotation; And the stroke that does not need the motor rotation.For example, needing the stroke of motor rotation is the stroke that rotates at washing, rinsing, dehydration intermediate roll, impeller and stirrer; The stroke that does not need the motor rotation is to supply water and the draining stroke.If stroke is the stroke that needs the motor rotation noted earlier, judge that then the stroke that will carry out is high speed rotating or low speed rotation.Can determine high speed stroke and low speed stroke in advance according to running status, for example, washing and rinsing can be the low speed strokes, and the dehydration stroke can be a high speed stroke.
If carry out the high speed rotating stroke, motor is a three-phase operation.Comparatively speaking, because the motor high speed rotating can produce considerable noise usually, and motor makes with three-phase operation in the high speed rotating stroke, even torque is low, the motor that moves with the three-phase operation method only produces a small amount of noise.Different therewith, if carry out the low speed rotation stroke, motor is two-phase operation.In the low speed stroke, motor is two-phase operation, if because motor under the situation of the stroke of for example doing washing, comprises clothes and water with low speed rotation in the cylinder usually, the sense of rotation of motor changes frequent, and the rotation of motor can be subjected to many resistances.Therefore, in the low speed stroke, motor is two-phase operation, and its torque is big.When motor during,,, therefore can not bring any offending sensation to the user because the noise that it produces when being stirred clothes covers even produce a small amount of noise in two-phase operation.
The two-phase operation method and the three-phase operation method of motor recited above will be described in more detail below.
Next stroke after a stroke of washing machine finishes, is determined in continuity ground; If the low speed rotation stroke then carries out the two-phase operation method,, carry out the next one operation stroke of washing machine then if the high speed rotating stroke then carries out the three-phase operation method.
On the other hand, the two-phase operation method of motor and the required data of three-phase operation method are stored in and are used as invoked information in the storer 7.When implementing the two-phase operation method, call first look-up table and be used as reference signal; When implementing the three-phase operation method, call second look-up table and be used as reference signal.In addition, look-up table information and the carrier signal of calling compared, and the signal of output relatively is imported in the inverter 4 as switching signal by control section 6.
The process flow diagram of the explanation washing machine operation method that provides according to Fig. 2 can be understood the operation method of above-mentioned washing machine.
Describe the operation method of washing machine in detail with reference to Fig. 2: determine at first whether motor moves (St1).As the step of directly carrying out washing stroke, rinsing stroke and dehydration stroke, and as the step of the cylinder that is used to do washing, impeller and stirrer rotation, the motor operation step is divided into the motor low speed rotation stroke that is used for washing stroke and rinsing stroke and is used to dewater the motor high speed rotating stroke of stroke.
Then, determine whether motor carries out the step (St2) of high speed rotating, if determine it is the high speed rotating pattern, then motor carries out three-phase operation step (St3); If determine it is the low speed rotation pattern, then motor carries out two-phase operation step (St4).
According to the washing machine working condition, can pre-determine whether carry out motor high speed rotating step according to a series of travel condition that is stored in advance in the storer.
Stroke alteration motor operation method according to washing machine can make washing machine have best torque and noise situation according to the washing machine stroke.Particularly, produce high torque (HT), because DC link (DC-link) utility ratio of motor is up to nearly 100% under the two-phase operation operating mode of motor, thus produce high torque (HT), but produce a large amount of harmonic waves, so in operational process, produce many noises.Compare with the two-phase operation operating mode, motor is under the situation of three-phase operation method, and the utility ratio of DC link is low, is approximately 87%, and the low harmonic wave that still produces hardly of torque is so it is applicable to when requiring the low noise operation.
Fig. 3 illustrates the example of motor three-phase operation method, and Fig. 4 illustrates the example of motor two-phase operation method.The three-phase operation method is by sinusoid pulse width modulation modulation (SPWM, Sinusoidal Pulse WidthModulation) carries out, the two-phase operation method is carried out by dead band sinusoid pulse width modulation modulation (DPWM, Dead-band sinusoidal Pulse Width Modulation).
With reference to Fig. 3 to 4, (a) among Fig. 3 and (a) among Fig. 4 illustrate the situation of change of carrier signal 11,21 and reference signal 12,22, and at least a portion carrier signal and sinusoidal wave reference signal that copped wave is shown compare mutually.(b) among Fig. 3 and (b) among Fig. 4 illustrate the variation figure that two signals is compared the phase voltage (line-to-neutral) of back output through comparer.And (c) among Fig. 3 and (c) among Fig. 4 illustrate the situation of the signal Fourier transform frequency analysis on frequency domain in Fig. 3 (b) and 4 figure (b).
With reference to (b) among Fig. 3 and (b) among Fig. 4, to compare carrier signal 11,21 identical with reference signal 12,22; Reference signal 12 is continuous copped wave, but reference signal 22 is discontinuous copped wave in SPWM, and spends to there being 120 degree not have signal between 360 degree 0.Therefore, in SPWM, the operation signal that PWM changes is input in whole three-phases of motor 5 continuously, still, in DPWM, passes through to import with the phase places of 120 degree interval variation according to carrier signal 21 constant (ON) signals.For DPWM, because there are 120 degree can not input reference signal 22, this part be called dead band (Dead-band).According to these methods, in DPWM, the motor operation signal of variation only is transfused in the two-phase, and because this reason, DPWM always uses in the two-phase operation method.
In addition, with reference to (c) among Fig. 3 and (c) among Fig. 4, compare with the three-phase operation method, the two-phase operation method produces more harmonic wave, so produce a large amount of noises owing to these harmonic waves when motor operation.
(d) among Fig. 3 and (d) among Fig. 4 illustrate the output waveform figure of SPWM and DPWM method neutral voltage (a line anda line), and (e) among Fig. 3 and (e) among Fig. 4 illustrates (d) and the situation of the Fourier transform frequency analysis of signal on frequency domain in (d) among Fig. 4 among Fig. 3.
With reference to (d) among Fig. 3 and (d) among Fig. 4, to compare with the SPWM method, the utility ratio of the DC link of DPWM method is higher, along with the increase of working portion (duty-on), therefore significantly, produces high torque (HT) in the two-phase operation of using the DPWM method.
With reference to (e) among Fig. 3 and (e) among Fig. 4, to compare with the SPWM method, the DPWM method produces more harmonic wave, therefore significantly, produces more noise in the two-phase operation of using the DPWM method.
Illustrated that more than the stroke according to washing machine can adopt different motor operation methods.Specified that the motor by the control of DPWM method adopts the two-phase operation method to be fit to be applied in washing stroke or the rinsing stroke, in these operation strokes of washing machine, needed high torque (HT).Be fit to is because though produced noise in measurement, obtained high torque (HT).In addition, be fit to be because, though in motor, produced noise because it is blended in the noise of stirring during clothes, so the offending sensation of bringing to the user is seldom.In addition, although washing stroke and rinsing stroke are low speed rotation, because flip-flop sense of rotation continually, so be more suitable for adopting the two-phase operation method that the DPWM method is controlled of pass through that produces high torque (HT).
In addition, in the dehydration stroke with high speed rotating in the operation stroke, be fit to adopt three-phase operation method, though, can obtain the operating condition of low noise because torque is low by SPWM control.In addition, in the dehydration stroke, although be high speed rotating, sense of rotation does not often change.Owing to do not need high torque (HT) under this rotating condition, and just can obtain enough power with low torque, more suitable employing is by the motor three-phase operation method of SPWM method control.
Refer again to Fig. 2: if be defined as low speed rotation pattern (St2), then motor carries out two-phase operation (St5); At first, call first look-up table (St6) in the storer 7; In control section 6, produce switching signal (St7) after the reference signal of first look-up table and carrier signal compared.Then, this switching signal is as the switching signal of inverter 4; Then, in inverter 4, produce direct motor operation signal; Offer motor 5 back motor rotations (St8).
In addition, in the step (St2) of determining the high speed rotating pattern; If determine it is the high speed rotating pattern, then carry out three-phase operation (St3); At first, call second look-up table (St6); In control section 6, produce switching signal (St7) after the reference signal of second look-up table and carrier signal compared.Then, this switching signal is as the switching signal of inverter 4; In inverter 4, produce the motor operation signal; Offer motor 5 back motor rotations (St8).
According to the present invention who proposes, particularly, when the stroke that carries out driving under the low noise condition during as the dehydration stroke, because motor is the three-phase operation by the SPWM method, although torque is low, washing machine can be worked under required low noise condition.
And particularly, when washing stroke that needs high torque (HT) to drive or rinsing stroke, because motor is the two-phase operation by the DPWM method, although there is noise to produce in measurement, washing machine can be worked under required high torque (HT) condition.
As described above, according to the operation method of washing machine of the present invention: need not increase the structure of complicated similar hardware, only in storer 7, store two kinds of look-up tables, according to the two-phase operation method of DPWM method; Enforcement according to the motor three-phase operation method of SPWM method can realize.
Therefore, without adjunct circuit or unnecessary cost consumption, the operation method of washing machine can adapt with the impulse stroke of washing machine.

At first, main points of the present invention are that the motor of washing machine is rotated according to condition of work and diverse ways, and condition of work is promptly washed with the rinsing stroke needs high torque (HT) and low noise condition, and the dehydration stroke needs low noise and low torque condition.When washing machine carried out such operation, the low noise of classifying according to the operation of washing machine had improved user's satisfaction, had realized the job stability of washing machine by high torque (HT), and had improved washing efficiency.
In addition, additional structure that need not similar hardware only increases a spot of information in storer, and for example some look-up tables are applied to respectively make motor operation on the different phase place and the number of phases, have realized the invention effect, have reduced manufacturing cost.
In addition, reference signal of using in the DPWM method and carrier signal are not limited to top described, can use various forms of coherent signals.Yet, during the motor two-phase operation, in the DPWM method, form the dead band with certain interval.Equally, in motor three-phase operation method, can use various reference signals and carrier signal.In addition,, can propose various forms of motor operation methods, compare, need under the situation of low noise the multi-phase operation method better with the situation that needs high torque (HT) according to operation method.
In addition, among another embodiment, when carrying out certain one stroke according to the washing machine stroke, a certain stage of motor, another stage may be with three-phase work with two-phase work, and this within the scope of the present invention.Yet, preferably, only two-phase work entirely when two-phase operation, and only three-phase work entirely when three-phase operation.
In addition, aspect device, it is feasible storing two look-up tables and calling in needs according to the motor operation method.But the situation of carrying out according to stroke is stored a plurality of look-up tables in washing machine, and it also is feasible calling more suitable look-up table as required and using.In addition, use algorithmic approach rather than use with the method for look-up table stores in storer formation reference signal when wanting of can in officely what is the need for.In office what is the need for can form reference signal for better when wanting.
In addition, in various types of washing machines, the present invention can be applied to various rotary bodies, for example cylinder, impeller and stirrer, and preferably, cylinder is more suitable, because it is not subjected to the influence of the water yield, so comparatively speaking, the load of rotary body is applied for identical.
