Simultaneously, described configuration of devices of hereinafter or control method only are used to describe embodiments of the invention, and are not used in the Patent right scope of the present invention that limits.
Fig. 1 shows the decomposition diagram of washing machine.
With reference to Fig. 1, washing machine comprises: casing 110, and this casing 110 constitutes the outside of washing machine; Bucket 120, this bucket 120 is supporting in said casing and by said casing; Cylinder 130, this cylinder 130 rotatably are installed in this bucket so that pack clothing in this bucket into; Motor 140, thus this motor 140 makes the cylinder rotation through apply torque to cylinder; And control panel 115, can make the user select washing process and make the operation of this washing process.
Said casing 110 has: main body 111; Lid 112, the front portion of being coupled to this main body; And top board 116, the top side of being coupled to this main body.Said lid 112 can comprise: opening 114 is used for advancing/going out of clothing; And door 113, be used for the optionally opening/closing of said opening.
Therefore, control panel 115 comprises: operating unit 117 and 118 is used for the user's control commands input; And display unit 119, be used to show the control information of control command.Control panel 115 can comprise: control module, be used for controlling the operation of this washing machine according to control command, and the operation of this washing machine comprises the operation of motor.
According to the method that is used to control washing machine of the present invention, cylinder can be controlled so as to the drive movement with various patterns.That is, the method that is used to control washing machine of the present invention not only comprises flip-flop movement and spin motion, also comprises the drum movement different with above-mentioned motion.This flip-flop movement is the motion of a kind of like this drum driven, wherein, in the process of the washing of clothing or rinsing, clothing is risen and falls; And this spin motion is a kind of like this drum movement, and wherein, clothing is attached in the inboard state of cylinder and makes clothing keep rotation when spin.
" drum movement " is the rotary mode of cylinder, and wherein, thereby the direction of rotation of cylinder and speed are controlled the motion of clothing in cylinder is set.Therefore, if thereby washing machine has various drum movement can make the clothing in the cylinder move by variety of way during washing, then the effect that can improve washing performance can be provided.
Hereinafter can be applicable to detailed description the various drum movement of various embodiments of the present invention.
Fig. 2 A～2G shows the sketch map of multiple drum movement respectively.
As stated, drum movement is a kind ofly to be used for combining the direction of rotation of cylinder and speed that the drum driven method of clothing in the motion of cylinder is set.This drum movement produces through controlling this motor, and the motion of clothing in cylinder determined by drum movement.
Because when cylinder rotates, clothing is risen and the whereabouts, so if the direction of rotation of cylinder and speed are controlled, the physical force that then will be applied to this clothing can be changed through the bump on the inner circumferential surface of cylinder 135.According to this point, the degree of bump (impulsive force) clothing can be changed when frictional force (friction between the clothing, the friction between clothing and the washings) or washing, and the degree that makes the clothing in the cylinder untie, scatter or put upside down can be changed.
Correspondingly; Can change drum movement according to the detailed step of pollution level, each process and each process of the kind of clothing, clothing because have the washing machine of various drum movement; So this washing machine can make lauderability reach maximum; And can solve various problems, such as the delay of the wash time section that under the situation of washing, occurs etc. with consistent drum movement.
Simultaneously, in order to produce various drum movement, preferably, motor 140 is direct drive motor.That is, a kind of like this configuration of motor is preferable: the stator of motor firmly is fixed to the rear portion of this barrel 120, and the rotor of motor is connected to this cylinder, makes motor directly make cylinder 130 rotations.This is because direct drive motor helps promptly to control the direction of rotation and the torque of motor.Therefore, can index drum motion under the situation of non-time delay or idle running.
Yet; If this washing machine only produces drum movement (such as flip-flop movement or spin motion) and this drum movement and do not mind above-mentioned time delay or idle running, then this washing machine can have and a kind ofly like this disposes the torque that makes from motor and be delivered to cylinder through pulley and belt.Yet; Probably cause above-mentioned time delay or idle running to transmission of torque to a kind of like this drive mechanism of cylinder through pulley and belt from motor; If this washing machine has the drum movement of a kind of needs cylinder action rapidly, is a kind of like this drive mechanism that revolving force passes to cylinder preferable through direct drive motor then.
Fig. 2 A shows the sketch map of rolling movement.This rolling movement is a kind of like this drum movement; Wherein, motor 140 rotates cylinder 130 in one direction and makes clothing on the cylinder inner circumferential surface on the cylinder direction of rotation, drop to the direction of cylinder minimum point from the position (the motion angle is less than about 90 degree) that is lower than about 90 degree.
Promptly; If motor 140 makes cylinder rotate by about 40RPM; Then the clothing of the lowermost of cylinder 130 can rise to certain height and from direction of rotation, dropping to cylinder minimum point less than a position of about 90 degree from the cylinder minimum point, just look like that this clothing is rolling on the direction of rotation of cylinder 130.When cylinder rotates in the clockwise direction, seem that this clothing remains on the third quadrant rotation of cylinder.
Through clothing that above-mentioned rolling caused and the friction between the washings, friction and the friction of clothing and cylinder inner circumferential surface between the clothing, just clothing is washed.This motion is reversed clothing fully, thereby the effect of this clothing that softly rubs can be provided.
Therefore, confirm the RPM of this cylinder, make this rolling produce frictional force and less than the centrifugal force of gravity 1G.
Yet, preferably, confirm the RPM (revolutions per minute) of cylinder with respect to the radius of cylinder.That is, because the RPM of cylinder is big more, the centrifugal force that acts on the clothing in the cylinder is just strong more, so the motion of the official post clothing of centrifugal force and gravity is different.In addition, consider the revolving force of cylinder and the friction between cylinder and the clothing, also can confirm the RPM of this cylinder.
Fig. 2 B shows the sketch map of flip-flop movement.
This flip-flop movement is a kind of like this drum movement, and wherein, motor 140 rotates cylinder 130 in one direction and makes clothing on the cylinder inner circumferential surface on the cylinder direction of rotation, drop to the direction of cylinder minimum point from the position of about 90～110 degree.This flip-flop movement is the drum movement that is used in usually in washing and the rinse cycle, just produces mechanical force (frictional force between the clothing etc.) when rotating by suitable R PM in one direction because this flip-flop movement only is controlled so as at cylinder.
Before motor 140 is driven, be loaded into the minimum point that clothing in the cylinder 130 is positioned at cylinder 130.When motor 140 when cylinder 130 provides torque, cylinder 130 has just rotated, thereby makes the bump 135 on the inner circumferential surface of this cylinder be lifted to clothing from the cylinder minimum point height of cylinder.If motor 140 makes cylinder 130 rotate by about 46RPM, then this clothing position from about 90～110 degree on this cylinder direction of rotation drops to the direction of cylinder minimum point.
In this flip-flop movement, the RPM of this cylinder is set, make centrifugal force that this flip-flop movement produced greater than the centrifugal force of above-mentioned rolling movement but less than gravity.
This flip-flop movement seems to make that clothing moves to the part between the third quadrant and second quadrant from the cylinder minimum point, removes from the inner circumferential surface of cylinder, and drops to the direction of minimum point.
Correspondingly; Because this flip-flop movement can wash this clothing through the caused impact of falling of friction between clothing and the washings and clothing, so this flip-flop movement can wash and rinsing with the mechanical force stronger than the mechanical force of above-mentioned rolling movement.And,, clothing is untied and the effect of separating (scattering) so this flip-flop movement has because this flip-flop movement is a kind of whereabouts motion that makes clothing remove certain degree from the cylinder inboard.
Fig. 2 C shows the sketch map of the motion of marking time.This motion of marking time is a kind of like this drum movement, and wherein, motor 140 rotates cylinder 130 in one direction and makes clothing on the cylinder inner circumferential surface on the cylinder direction of rotation, drop to the direction of minimum point from peak (positions of about 180 degree).
If motor 140 makes cylinder 130 by being rotated greater than about 60RPM, then can not fall because of this clothing rotation of cause of centrifugal force.This motion of marking time is a kind of like this motion; Wherein, Through making cylinder this clothing can not fallen because of the cause of centrifugal force, thereby make the momentum that acts on this clothing reach maximum from the cylinder inner circumferential surface by certain speed rotation and this speed, and the rotation of braking this cylinder suddenly.
In this motion of marking time; Control motor 140; So that cylinder 130 makes clothing can not fall because of the cause of centrifugal force by certain speed (greater than about 60RPM) rotation and this speed; And apply reverse torque to cylinder 130 when being positioned near the peak (direction of rotation is the point of 180 degree, and on the direction of rotation of cylinder, the motion angle is 180 degree) of cylinder when this clothing.
Therefore; Because clothing begins to rise and makes that time that cylinder stops drop to the direction of cylinder minimum point from the peak of cylinder 130 in the opposing torque of motor 140 from the minimum point of cylinder 130 on the cylinder direction of rotation, so the motion that this motion of marking time is the impact that produced when using clothing in the cylinder to fall at place, the highest top washs this clothing.The mechanical force that this motion of marking time is produced is greater than above-mentioned rolling movement or flip-flop movement.
This motion of marking time looks like such: when cylinder rotated in the clockwise direction, clothing moved to the cylinder peak from the cylinder minimum point through the third quadrant and second quadrant, and drops to the cylinder minimum point suddenly.The little then this motion of marking time of the amount of clothing has the maximum distance of fall in cylinder because compare this motion of marking time, so if can more effectively provide momentum to clothing with other motion.
Simultaneously, preferably, motor 140 can produce plugging (or reversing braking), to brake this cylinder.This plugging is a kind of like this motor brake method, wherein, on the direction opposite with the present direction of rotation of motor, makes this motor rotation to brake this motor.In order on the direction opposite, to produce revolving force, can make the phase place anti-phase of the electric current that just is being provided for this motor with the direction of rotation of motor.This plugging makes unexpected braking become possibility.Therefore, this plugging is best suited for the braking method of this motion of marking time, and can strong impact be provided to clothing.
Then, motor 140 applies torque to cylinder 130 once more, so that the clothing of cylinder lowermost rises to peak.Promptly; Applying torque so that after cylinder 130 rotated in the clockwise direction, cylinder rotated in the counterclockwise direction cylinder is stopped suddenly thereby moment applies torque, then; Apply torque once more so that cylinder rotates in the clockwise direction, produce the above-mentioned motion of marking time thus.
At last, this motion of marking time is a kind of like this drum movement, and wherein, through the friction between washings and the clothing when cylinder rotate, also the momentum of this clothing whereabouts when being in the cylinder peak at clothing is realized the washing of this clothing.
Fig. 2 D shows the sketch map of oscillating motion.This oscillating motion is a kind of like this drum movement, and wherein, motor 140 rotates cylinder 130 two-wayly, and clothing is being fallen near about 90 degree (the motion angle of about 90 degree on the direction of rotation at cylinder) on the cylinder direction of rotation.
That is, if motor 140 makes cylinder 130 in the counterclockwise direction by about 40RPM rotation, then the clothing of cylinder lowermost rises to anticlockwise direction.In this example, before clothing arrived 90 degree points, motor stopped the rotation of cylinder, made near the direction that drops to the cylinder minimum point 90 degree of clothing on the counter clockwise direction.
Then, motor 140 makes cylinder 130 in the clockwise direction by about 40RPM rotation, thereby the clothing that causes to fall and break rises to the certain altitude on the cylinder direction of rotation.Simultaneously, arrive along clockwise direction at clothing before the 90 degree positions of cylinder, motor 140 stops the rotation of cylinder, makes clothing from dropping to the direction of cylinder minimum point near 90 degree of cylinder in the clockwise direction.
That is, this oscillating motion is a kind of like this motion, wherein; The rotation of a direction of cylinder with stop and the rotation of another direction of cylinder with stop to be repeated; Seem to make this clothing to repeat a kind of like this motion, wherein, this clothing rises to the part of second quadrant and from the soft dropped of there from the third quadrant of cylinder; Then, this clothing rises to the part of first quartile and from the soft dropped of there from the four-quadrant of cylinder.
In this instance, resistive braking is used to brake this motor 140, thereby makes the load of motor 140 and mechanical wear reach minimum and control the impact that imposes on clothing.
This resistive braking is a kind of like this braking method, and this braking method uses the action as the generator of motor, when the electric current that offers motor is closed, can produce this action as the generator because of its rotatory inertia.Be closed if offer the electric current of motor, then because the sense of current in the motor winding becomes opposite with the sense of current before of cutting off the power supply, so thereby on the direction that hinders the motor rotation, brake this motor effectively in action.Different with above-mentioned plugging, this resistive braking is unexpected brake motor, but changes the direction of rotation of cylinder reposefully.
Therefore, this oscillating motion looks like such: the motion mode of clothing similarly is the numeral " 8 " of in third and fourth quadrant of cylinder, falling.
Fig. 2 E shows the sketch map of cleaning motion.This scouring campaign is a kind of like this drum movement; Wherein, Motor 140 rotates cylinder 130 two-wayly, and makes clothing fall (this clothing falls from the position greater than the motion angle of 90 degree on the cylinder direction of rotation) surpassing about 90 degree parts on the cylinder direction of rotation.
That is, if motor 140 makes cylinder 130 in the counterclockwise direction by rotating greater than about 60RPM, then clothing rises to certain height from the cylinder minimum point in the counterclockwise direction.In this example, after this clothing surpassed the position of about 90 degree on the counter clockwise direction of this cylinder, motor provided opposing torque to this cylinder, so that the rotation of this cylinder stops at once.Then, this clothing separates or falls from the inner circumferential surface of this cylinder suddenly.
Then, motor 140 makes cylinder in the clockwise direction by about 60RPM rotation, so that clothing is lifted to certain height in the clockwise direction and cleans this clothing through the inner periphery of this cylinder.When this clothing had surpassed the 90 degree point of this cylinder in the clockwise direction, motor 140 provided opposing torque so that this cylinder stops at once to cylinder 130.Afterwards, motor makes cylinder rotate in the counterclockwise direction once more.Therefore, the clothing that separates from the cylinder inner circumferential surface will fall from the cylinder inner circumferential surface, and in the process that falls, the inner periphery of cylinder will be cleaned this clothing.
This scouring moves through and clothing is plunked down from above-mentioned height wash this clothing.Simultaneously, preferably,, make motor 140 brakings through plugging.
This scouring campaign can have very strong washing friction effect, because the flip-flop of direction of rotation makes clothing fully not leave the inner circumferential surface of cylinder.This scouring campaign is a kind of motion of repetition, wherein, clothing through third quadrant move to second quadrant a part and from the there plunk down, through four-quadrant move to first quartile a part and from the there plunk down.Therefore, this scouring campaign seem to make clothing along the inner circumferential surface of cylinder repeatedly go up/descend to move.
Fig. 2 F shows the sketch map that filters motion.This filtration campaign is a kind of like this drum movement, and wherein, motor 140 makes cylinder 130 rotations, makes clothing can not fall from the cylinder inner circumferential surface, simultaneously to drum jet cleaning water.
That is, in this filtration campaign, washings are injected into drum, and clothing is unfolded, closely contacts the inner circumferential surface and the rotation of cylinder simultaneously, make washings leave this cylinder 120 and pass penetrating hole 131 because of centrifugal force sees through this clothing.Therefore, because filter the surface area that motion makes washings penetrate this clothing and enlarged this clothing simultaneously, offered a kind of like this effect of this clothing equably so can obtain washings.
In this filtration campaign, through using circulating water flow passage (not shown) and pump, make the washings circulation in the bucket, so just can jet cleaning water.
Fig. 2 G shows the sketch map of compressional movement.This compressional movement is a kind of like this drum movement, and wherein, motor 140 repeats following operation: make cylinder 130 rotations, thereby make clothing can not fall from the cylinder inner circumferential surface; And reduce rotary speed, thus make clothing remove from the cylinder inner circumferential surface, washings are injected in the cylinder simultaneously.
That is, compressional movement is different from and filters the motion part and be: in filtering motion, the rotary speed of clothing can make clothing not remove from the cylinder inner circumferential surface; In compressional movement, the rotary speed of cylinder changes, and removes thereby clothing repeatedly is attached on the cylinder inner circumferential surface and from the cylinder inner circumferential surface.
Although during filtering motion and compressional movement, provide the process of washings not to be displayed among Fig. 1, just can realize this process through using circulating water flow passage and pump to cylinder 130.The pump that is connected to bucket 120 bottom surface pressurizes to washings, and the circulating water flow passage can be configured to make the one of which side to be connected to pump and make its opposite side can be from the cylinder top side to the roller spray washings.
Yet, because circulating water flow passage and pump are used to spray the washings from bucket, so following situation is not got rid of in the injection of washings: through being connected to the injection water supply flow channel of the outside watering of casing, to the roller spray washings.
That is, if this injection water supply flow channel makes the one of which side be connected to watering and make its opposite side be connected to bucket and have the nozzle that is used for to the roller spray washings, then can jet cleaning water during filtering motion or compressional movement.
Fig. 3 A～3D shows the sketch map of the details of the motion of marking time.Because just on this direction, rotate along a direction this cylinder when cylinder 130 applies torque, so clothing is closely rising in the contact cylinder inner circumferential surface at motor 140.In this instance, preferably, drum rotation speed surpasses about 60RPM, makes clothing closely rise in the contact cylinder inner circumferential surface.In this instance, confirm the rotary speed of this cylinder with respect to the inside radius of cylinder, this rotary speed makes centrifugal force become greater than gravity.
In order just before clothing arrives the cylinder peak through the degree of 90 on the direction of rotation of cylinder 130 point, cylinder to be stopped the rotation at once, make motor 140 stand plugging.Because it is closely related to make motor 140 stand the time point and the position of clothing in cylinder 130 of plugging; So preferably; Be used for equipment (checkout equipment that for example, has Hall effect transducer) definite or prediction clothing position and be provided for this motor so that confirm the anglec of rotation of rotor.
Through Hall effect transducer, control module not only can be confirmed the anglec of rotation of rotor, can also confirm the direction of rotation of rotor, and its detailed description will be removed, because relevant with it content all well known to a person skilled in the art.
Control module can be confirmed the anglec of rotation of cylinder through checkout equipment, and can before cylinder arrive 180 degree, control motor 140 and make it stand plugging.As stated, plugging means and applies negative-phase sequence curent so that cylinder rotates in the opposite direction.For example, plugging means and is applying electric current to motor so that it suddenly applies electric current so that it rotates in the counterclockwise direction to motor after rotating in the clockwise direction.
Therefore, the cylinder of rotation roughly stops at the angle place of 180 degree at once in the clockwise direction, thereby makes clothing drop to the direction of the minimum point of drum from the peak of drum.Then, keep applying of electric current, thereby let cylinder keep rotation in the clockwise direction.
Although Fig. 3 shows the situation that cylinder is rotated in the clockwise direction, though make cylinder carry out during the rotation counterclockwise above-mentioned mark time to move also have no relations.Yet, preferably, because the motion of marking time has brought very heavy load to motor 140, so preferably under the situation that reduces its clean effect ratio, implement this motion of marking time.
This clean effect ratio is the ratio that the motor driven time period adds section sum quiescent time with respect to the driving time section.If this clean effect ratio is one, this means that then motor is driven always and do not stop.Preferably, consider the load on the motor, for example, through drive motor motor was stopped 4 seconds, this motion of marking time just has about 70% clean effect ratio.
Fig. 4 A～4F shows the sketch map of the details of cleaning motion.If motor 140 applies torque to cylinder 130, then the clothing in the cylinder rotates in the clockwise direction.Preferably, control motor 140, so that cylinder 130 is pressed greater than about 60RPM rotation, clothing closely contacts the inner circumferential surface of cylinder when rotated like this.Then, because surpassing on the cylinder direction of rotation when 90 of cylinder is spent point, clothing make motor 140 stand plugging, so this clothing drops to the direction of the minimum point of cylinder along the inner circumferential surface of cylinder.
If clothing drops to the minimum point of cylinder, then motor 140 provides torque, and this torque is rotated cylinder in the counterclockwise direction.Therefore; When rotating in the counterclockwise direction, the clothing that falls so closely contacts the inner circumferential surface of cylinder; And; Because make motor stand plugging, so just drop to the cylinder minimum point along the cylinder inner circumferential surface with clothing that the cylinder inner circumferential surface closely contacts when time between 90 degree points of the cylinder of clothing on counter clockwise direction and the cylinder peak.
Yet perhaps, after plugging, and then, motor just provides the torque that cylinder is rotated in the counterclockwise direction.That is, when 90 of the cylinder of clothing on clockwise direction spent between point and the cylinder peak, can make motor stand plugging, and be right after after plugging, motor provides the torque that cylinder is rotated in the counterclockwise direction.Therefore, the clothing that separates with the cylinder inner circumferential surface drops to the direction of cylinder minimum point along the cylinder inner circumferential surface.In the process that falls, the circumferential surface of cylinder this clothing that can rub.
Just as the motion that kind of marking time; Also motor 140 is applied very heavy load because clean motion, so preferably, implemented this scouring campaign reducing to act on only under the situation of ratio; For example; After implement cleaning motion 10 seconds, motor was stopped 4 seconds, motor just comes work by 70% clean effect ratio like this.
Simultaneously; The method that is used to control washing machine of preferred embodiment can comprise motion (another title is a first motion) formerly according to the present invention; Wherein in each drum movement before making the cylinder rotation on the set direction (clockwise direction or counterclockwise); With drum movement in make on the opposite direction of rotation of set direction of rotation after cylinder rotated predetermined angle, with drum movement in make the cylinder rotation on the identical direction of rotation of set direction of rotation.
When implementing this drum movement; If in this drum movement, directly make cylinder on the set direction by speed (rpm of the setting) rotation of setting; Then current peak can occur, the current's intensity that in this current peak, just is being provided for motor rises sharp.
The clothing of this cylinder is static because before drum movement begins, pack into; And the load when cylinder rotates on this motor between the 90 degree point of the cylinder on cylinder minimum point and the direction of rotation is maximum, so need very high current strength be provided to motor in the starting stage of implementing this drum movement.Particularly, if the amount of clothing is big, thereby need higher current strength be provided to motor, the possibility that current peak then occurs is big, and the current's intensity that when this current peak, offers motor becomes high singularly.
Because the electric current present peak value might cause the safety problem of washing machine during initial drum movement, so the present invention's suggestion was carried out motion formerly so that realize this drum movement at an easy rate before implementing this drum movement.
This formerly moves and comprises: observation motion, wherein, with drum movement in make the cylinder rotation up to preset observation reference angle on the opposite direction of set direction of rotation; And accelerated motion, wherein, with drum movement in make the cylinder rotation up to preset acceleration reference angle on the identical direction of set direction of rotation.
Promptly; Because with drum movement in make the cylinder rotation after preset angle on the opposite direction of set direction of rotation; With drum movement in make the cylinder rotation on the identical direction of set direction of rotation; So this motion formerly not only can utilize the potential energy of the clothing that is obtained between this observation moving period of carrying out in the accelerated motion; Can also prevent the appearance of current peak, when when getting into this drum movement through cylinder after the accelerated motion, this current peak might appear at the starting stage of drum movement.
Simultaneously; Because offer motor so that cylinder to rotate to the maximum intensity of electric current of observation reference angle measured in observation motion; Thereby and in accelerated motion, make the cylinder rotation through the electric current that is provided at maximum intensity measured in the observation motion to motor, change along with laundry amounts so in accelerated motion, offer the electric current of motor.Finally, the method that is used to control washing machine of the present invention can prevent the appearance of current peak, and no matter laundry amounts how (hereinafter will be described in detail).
Fig. 5 A～5E shows in order to prevent the concept map of motion formerly performed before the drum movement that appears at of current peak; And Fig. 8 shows a flow chart, and this flow chart shows the step that is used to control the method for washing machine according to preferred embodiment of the present invention a kind of.
At first, will consider that this drum movement describes this and formerly move, and will consider that control method describes this and formerly move.
Basically, the motion formerly that offers control method of the present invention comprises observing moves and accelerated motion, and motion formerly can also be included in observation motion end afterwards performed inertia motion and performed change campaign after accelerated motion finishes.
Fig. 5 A shows that this cylinder is the sketch map of static a kind of like this state before drum movement begins.Fig. 5 B shows the sketch map of observation motion, wherein, is set up in drum movement and makes the cylinder rotation up to observation reference angle S under the situation in the clockwise direction.
If set direction of rotation is a clockwise direction in the drum movement; Then this cylinder is to rotate in the counterclockwise direction in the observation motion; And if set direction of rotation is counterclockwise in the drum movement, then this cylinder is to rotate in the clockwise direction in the observation motion.For ease, be that clockwise direction such a case is described with continuing with reference to direction of rotation set in the drum movement.
In the observation motion, cylinder has rotated preset reference angle S (observation reference angle) in the counterclockwise direction.This observation reference angle S is selected from 15～45 these important sections of degree; At this observation reference angle S place; Just can detect laundry amounts effectively through offering motor so that carry out the electric current (electric current is carried out in the observation motion) of observation motion, and Fig. 3 shows the situation when the angle that is provided with 22.5 degree.
In order to let cylinder rotate to observation reference angle S, require the control module (not shown) of washing machine electric current to be provided to motor, wherein, the current's intensity that offers motor when laundry amounts is big is different from the current's intensity that laundry amounts hour offers motor.
With reference to Fig. 6 A and 6B; Laundry amounts is big more; The intensity of the electric current that in observation motion, is provided (electric current is carried out in the observation motion) is just high more, and to offer motor so that carry out the intensity of the electric current (drum movement is kept electric current) of drum movement be the highest equaling under the situation that the half the laundry amounts of washing capacity is loaded into cylinder (half load state).This current's intensity is the highest in the half load state, and this is because the motion that equals the clothing in the washing capacity one half cylinder when laundry amounts is maximum.Served as the load on the motor because occur in the motion of the clothing in the cylinder during the drum movement, so in order to make cylinder by the rotary speed rotation of setting, just requiring provides bigger electric current to motor.
Simultaneously, if thereby the laundry amounts that surpasses half load condition is loaded into this cylinder has reduced to be used to the space that lets clothing in cylinder, move, and then the caused by movement load of clothing is little.Therefore, be provided for motor even the drum movement more required than half load state kept the little electric current of electric current, this cylinder also can be rotated by rotary speed set in this drum movement.
In addition, when laundry amounts during less than the half load state, the caused by movement load of clothing in cylinder do not kept electric current even as big as increasing drum movement, even be relatively very little because the motion of clothing is violent laundry amounts.
Simultaneously; Observing the maximum of the observation campaign execution electric current that offers motor between moving period controlled the unit in execution stores in the storage device (such as memory); So that control module will offer motor with the identical electric current of maximum of observation motion execution electric current in accelerated motion, hereinafter can be described this accelerated motion in detail.
One accomplishes when observing motion, just carries out inertia motion.This inertia motion is a kind of like this motion, wherein, if cylinder rotates to above-mentioned observation reference angle, then cuts off offering motor and carry out the electric current of rotation for cylinder, stops up to the rotation of cylinder.
The potential energy of the obtainable clothing of inertia motion of the accelerated motion that is used for next carrying out through use is for the acceleration of cylinder provides inertia motion.
Because the torque that motor provides to cylinder has been rotated cylinder, so even the observation motion is through with, cylinder and clothing still can rotate a certain angle through inertia.Therefore, if after observation motion finishes, inertia motion is provided, then through using the clothing that in observation is moved, obtained and the inertia of cylinder just can make the potential energy of clothing bigger.The position " A " of the clothing that is disclosed among Fig. 5 C is such point, and at this some place, as the result of observation motion, the potential energy of clothing will be maximum.Therefore; Because the accelerated motion that after inertia motion, will carry out (Fig. 5 D) will make through the potential energy that uses this clothing to have cylinder with drum movement in rotate on the identical direction of set direction of rotation, can reach minimum so in the section (between minimum point 0 among Fig. 5 D and the B point) that is subject to the current peak influence, offer the current's intensity of motor.
Simultaneously, offer the checkout equipment such as Hall element (Hall effect transducer) of motor, the maximum point A of the potential energy of the clothing that just can confirm from the observation motion, to obtain through use.
Because after observation motion finishes, begin to be cut to the power supply of motor, so cylinder and clothing will rotate a certain angle in the counterclockwise direction through observing the inertia that moves from a S.Yet if cylinder and clothing arrive the maximum some A of clothing potential energy, cylinder will stop and changing direction of rotation into clockwise direction.Therefore, if provide Hall element to detect stopping or changing of direction of rotation, then control module can be perceived the some A place whether clothing arrives the potential energy maximum, thereby makes control module accelerated motion shown in the execution graph 5D when clothing point of arrival A.
In accelerated motion; The observation campaign of maximum intensity is carried out electric current (or the value that electric current multiply by the amplification that predetermined ratio obtains is carried out in the observation campaign of maximum intensity) and is provided for motor so that cylinder with drum movement on the identical direction of set direction of rotation rotation up to the acceleration reference angle of presetting " B ".
Preferably, quicken reference angle and be set as such angle, this angle can farthest be utilized the potential energy that can from observation motion and inertia motion, obtain.Fig. 5 D shows an example, wherein, quickens the twice that reference angle is set as the formed angle [alpha] of potential energy maximum point A of cylinder minimum point 0 and clothing.
That is the formed angle of cylinder position B when, the formed angle of potential energy maximum point A that reaches through inertia motion of cylinder minimum point 0 and clothing equals cylinder minimum point 0 and finishes with accelerated motion.This is in order to utilize potential energy that obtains through the observation motion and the appearance that prevents current peak (with reference to Fig. 7 A), and when this current peak, the current value that offers motor in the section (0-B section) that the load on motor becomes maximum increases sharp.
As before summary, the current's intensity that in accelerated motion, offers motor equals in the observation motion, to offer the maximum intensity of the observation campaign execution electric current of motor.
Change with rotary speed set in the drum movement although will offer the current's intensity of motor, the current's intensity that the starting stage of the drum movement that begins to rotate from static state at cylinder will offer motor depends on laundry amounts closely.
Simultaneously; Cylinder rotates to the maximum intensity of the electric current of observation reference angle from the static state of cylinder because above-mentioned observation campaign carries out that the maximum intensity of electric current provides to motor, so maximum intensity that should observation campaign execution electric current can be predicted as the initial strength that makes cylinder in drum movement, begin to rotate required electric current from the static state of the cylinder of the identical clothing of packing on the set direction of rotation.Therefore; If the identical electric current of maximum intensity with above-mentioned observation campaign execution electric current in accelerated motion is provided for motor; The risk that then causes current peak (referring to Fig. 7 A) can reach minimum; Wherein, the load on the motor in the prior art becomes the current's intensity that offers motor in the maximum section (0-B section) and increases sharp.In addition; Thereby because accelerated motion makes the cylinder rotation in the maximum section of load (0-B section), reduce the load on the motor through using the potential energy that can from inertia motion, obtain, so this accelerated motion can further reduce to cause the risk (referring to Fig. 7 B) of current peak.
One accomplishes this accelerated motion, and control method of the present invention has just begun the change campaign that Fig. 5 E is disclosed.This change campaign is a kind of like this motion; Wherein, the current's intensity current's intensity (maximum intensity of electric current is carried out in above-mentioned observation campaign) that from accelerated motion, offers motor changes to the current's intensity that is used for keeping the set rotary speed of drum movement (rpm).
Monitor the anglec of rotation of cylinder through checkout equipment (such as Hall element); Just can confirm the start time point of above-mentioned change campaign, and begin to carry out each drum movement from that time that the current's intensity that offers motor takes place to change through this change campaign.
With reference to Fig. 8 consider a plurality of control steps discuss of the present invention formerly the motion.

After motor provides electric current, use checkout equipment to confirm whether cylinder has arrived observation reference angle S (with reference to Fig. 5) (S212) as the Hall element.And, if this cylinder does not arrive above-mentioned observation reference angle, so power supply so that motor keeps rotation on first direction, if confirm that this cylinder has arrived above-mentioned observation reference angle, then is cut to the power supply (S213) of this motor.
Simultaneously; In the observation motion; To the cut synchronization of power supply (S213) of motor, to carry out the maximum intensity (intensity of the warp amplification of maximum intensity that maybe should observation campaign execution electric current is the mean value of the maximum intensity of this observation campaign execution electric current maybe) of electric current measured and be stored (S214) for the observation campaign that makes cylinder rotate to the observation reference angle to provide.
Then, carry out inertia motion, wherein, cylinder and clothing are rotated through the inertia that from above-mentioned observation campaign, is obtained.And, in control method of the present invention,, detect this clothing and whether arrive maximum point A (with reference to Fig. 5) (S23) through potential energy from the inertia of observing motion in the centre of carrying out this inertia motion.
If this clothing arrives this maximum point A, control method then of the present invention is carried out accelerated motion S25.
In accelerated motion S25; Electric current is provided so that cylinder rotates up (direction identical with direction of rotation set in the drum movement) (S251) in second party to motor, this second direction equals the maximum intensity of above-mentioned observation campaign execution electric current with the opposite and current's intensity that provided of direction of rotation of when motion observation cylinder.
Then, in accelerated motion S25, confirm whether this cylinder arrives acceleration reference angle B (S252).And if confirm that this cylinder has arrived this acceleration reference angle, control method then of the present invention has just begun change motion S27.
In this change motion, the electric current that offers motor is that the maximum intensity that from accelerated motion S25, offers the observation campaign execution electric current of motor changes in order to keep the required electric current of rotary speed set in the drum movement (rpm).And afterwards, this cylinder is rotated by speed set in this drum movement.
Yet,, can save this change campaign according to the amount that is loaded into the clothing in this cylinder.Promptly; According to the amount that is loaded into the clothing in this cylinder; If offer motor, then do not need above-mentioned change campaign so that the current's intensity that cylinder is rotated by rotary speed set in the drum movement equals in accelerated motion, to offer the current's intensity of motor.
