Description
Technical field
The invention provides a kind of control method that is applied to roller washing machine, the method that adopts the band water distribution particularly belongs to household appliance technical field with the uniformity that improves clothing and distribute, in the hope of avoiding shaking the resonance point with fixed part.
Background technology
The consumer group of roller washing machine, the casing vibration is big when drying for inner core, noise problem of higher feedback is comparatively concentrated.Because drying period of roller washing machine is longer, the problems referred to above are brought inconvenience to the user and are easy to cause parts damages and the shortening in washing machine service life.
Trace it to its cause, exist vibration component (mainly being arranged at inside and outside cylinder assembly), 2 main resonance points of fixed part (as the shell place) in the internal structure of existing roller washing machine.Even can avoid the resonance point of vibration component when the index drum washing machine takes low speed to dry, but fixed part resonance still can form noise greatly when drying at a high speed when reaching.
If all take low speed to dry mode, need dry distribution and eccentricity values again repeatedly and detect, the cost of avoiding the low speed resonance point is that laundry time lengthening, power consumption rise.
As the distribution control method of applicant in first to file, application number is ZL200810187976.9, the title method for distribution control of drum type washing machine before drying clothes, its solution is to be begun by bleeding stage, successively by the slow-speed of revolution in the bleeding stage rotating, same direction is rotated the medium speed of fast rise after the stage, with the high rotating speed behind the slow ascent stage of last stage equidirectional, after this high stabilization of speed, judge the amount of unbalance size, when amount of unbalance during more than or equal to the severe amount of unbalance of program setting, slow-speed of revolution when rotating speed drops to draining, rotate 5-6 after second, begin redistribution from second stage, when continuous distributed does not still satisfy impulsive condition three times, restart to distribute by the phase I; When amount of unbalance directly enters the pre-spin-dry stage during less than the severe amount of unbalance.
With above-mentioned application formerly is the prior art of representative, and distribution and drying stage all are to carry out after all or part of discharge of washings.And actual conditions are, clothing is easy to be difficult to reach even distribution in the inner local accumulation that takes place of inner core when inner core rotates after washings are discharged.
If implement repeatedly to distribute, to choose less eccentricity value, after reaching requirement, eccentricity detecting, tends to take place the resonance problem of parts such as shell again to dry at a high speed as standard.
The roller washing machine distribution curve is undesirable in addition, and the little clothing (as bath towel, woollen sweater etc.) of surface area more is difficult to realize even distribution for those suctions are many.Even also reaching the eccentricity detecting requirement through for a long time distribution sometimes, long-time use also can cause the unusual or displacement of inner core rotation.
In view of this, the special present patent application that proposes.
Summary of the invention
Roller washing machine control method of the present invention, its purpose are to solve the problem that above-mentioned prior art exists and take mode with water distribution, i.e. after clothes washing or rinsing finished, washings were not discharged and promptly begun to distribute.Be under the prerequisite of carrier with washings, clothing is easy in the inner core slides within, reaches even distribution, the simultaneously satisfied instructions for use avoiding low speed, at a high speed resonate of clothing on a plurality of directions, reduces resonance noise.
Another goal of the invention is, according to the eccentricity detecting result, takes to dry rotating speed targetedly, is guaranteeing not cause that improving moisture under the prerequisite of resonance dries degree and clothes washing cleanliness factor.
Goal of the invention also is, forms clothing and distributes and the control effectively repeatedly of eccentricity detecting ground, to reach distributing homogeneity to greatest extent, avoids because of drying many parts damages factors of bringing by force at a high speed.
For achieving the above object, described roller washing machine control method mainly includes:
Washing stage, clothing is immersed in the water of inner core inside and washs.
Be with the difference of prior art, also include the following laundry control stage,
The clothing distribution phase, after the washing stage finished, washings were not discharged; The rotating speed of inner core increases to rotating speed b from zero; Under the drive of inner core, clothing distributes in washings;
In the eccentricity detecting stage, inner core remains under the state of rotating speed b, carries out eccentricity detecting at least one time; If eccentricity values greater than the severe eccentricity value, is then returned the clothing distribution phase; If eccentricity values less than slight eccentricity value, then continues to move next stage;
Draining dries the stage, and the rotating speed of inner core is increased to rotating speed c, simultaneously washings is discharged;
In the water level detecting stage, inner core remains under the state of rotating speed c, and whether the water level that detects inner core is zero, if then continue to move next stage;
Clothing dries the stage, and the rotating speed of inner core is increased to rotating speed d, and the moisture in the clothing is thrown out of;
The clothes washing EP (end of program).
As above-mentioned basic scheme feature, the drawback that distributes and dries after taking washings to discharge at prior art, the application are not discharged washings earlier after washing or rinsing finish.Because have washings in the inner core, clothing is easy to slide along barrel in inner core inside, along with inner core rotating speed ground improves, clothing and washings can be distributed on the barrel equably.
After clothing is evenly distributed, take a lower rotating speed in the draining drying stage, on one side draining improve the rotating speed of inner core on one side, thereby can avoid the low speed resonance point effectively.
On the basis that be evenly distributed at clothing, the low speed draining dries the stage, when clothing dries that the stage, inner core was taked higher rotation speed, also be easy to realize avoiding the high speed resonance point.
The application's primary key point is to take with water distribution, eccentricity detecting in turn to carry out the control stage that the low speed draining dries, dries at a high speed after up to standard.Not only be easy to reach clothing and be evenly distributed, and be easy to take repeatedly eccentricity detecting in above-mentioned a plurality of control stages, take corresponding solution at testing result.
Carry out improving the uniformity that clothing distributes to greatest extent before eccentricity values detects for being implemented in, can take ground further to optimize corrective measure to be, described clothing distribution phase, when the rotating speed of inner core reaches rotating speed a, stop inner core rotation 2-5 second, rotating speed a is less than rotating speed b;
The rotating speed of inner core (2) adopts a uniform acceleration respectively from zero 2 stages that increase to rotating speed a and increase to rotating speed b from rotating speed a.
As above improvement project, 2 distribution phase one dwell time section is set, clothing and washings can fall to the interior tube bottom that stops the rotation, this moment, clothing was easy to be adjusted to the centre on inner core bottom transverse, the longitudinal direction, promptly improved the uniformity of clothing in washings by 2 distributed operation.
2 distribution phase, inner core adopts a uniform acceleration respectively, helps the slip of clothing in washings, avoids clothing that distributing homogeneity takes place to twine and influence.
The range of speeds that comparatively preferably distributes is, increases to the stage of rotating speed a from zero at the rotating speed of inner core, and the uniform acceleration of employing is 8-12 revolutions per second, and rotating speed a is between 55-80rpm.
Perhaps, increase to the stage of rotating speed b from rotating speed a at the rotating speed of inner core, the uniform acceleration of employing is 3-5 revolutions per second, and rotating speed b is between 80-110rpm.
Big or problems such as obviously windings take place clothing for the reply clothing degree of eccentricity that may occur, the application takes urgent coping style in the eccentricity detecting stage, promptly when eccentricity values during greater than the severe eccentricity value, directly stops detection;
The rotating speed of control inner core is 50-60 revolutions per second, changes and to stop than 10 seconds: 10 seconds, take the mode of rotating alternate run; Continue 3-10 minute (duration is set according to different program for washing), return the clothing distribution phase.
In case the clothing eccentricity values surpasses the severe eccentricity value, then be difficult to avoid the low speed resonance point if proceed the draining drying stage, after entering the clothing drying stage, also just can't avoid the high speed resonance point certainly.
This is taked above-mentioned improved procedure,, distribute serious eccentric or problems such as winding take place in the hope of solving clothing by one period forced service stage when eccentricity values during greater than the severe eccentricity value.Then return the clothing distribution phase again, just can more efficiently reach the standard that is evenly distributed.
When serious problem pockety solve occurring, consider the overall operation time of program for washing, the maximum number of times that can set a clothes washing program eccentricity detecting are m.
When the detection number of times reaches m, eccentricity values still greater than the severe eccentricity value, then directly washings are discharged, control inner core subsequently and under the state of rotating speed b, move to the clothes washing EP (end of program).
That is to say, when the detection number of times reaches extreme value, can select to discharge by force the control mode of washings and low speed drying, can avoid the low speed resonance point and finish this controlling program of washing as soon as possible to avoid the high speed resonance point and to wish.
For avoiding the low speed resonance point effectively, the refinement solution that can take is that in the draining drying stage, the rotating speed c of inner core (2) is between 110-300 rev/min.
Can set eccentricity values and be divided into eccentric 3 class of slight off-centre, medium off-centre and severe, and dry the stage at clothing successively, take drying at a high speed, middling speed drying and low speed to dry accordingly;
Under the high speed drying state, the rotating speed of inner core is more than the 800rpm;
Under the middling speed drying state, the rotating speed of inner core is 450-800rpm;
Under the low speed drying state, the rotating speed of inner core is 350-450rpm.
In sum, the advantage and the beneficial effect that have of roller washing machine control method of the present invention is:
1, takes to be with the water distribution mode, after clothes washing or rinsing end promptly is that carrier carries out distributed operation with washings, clothing is easy to be distributed in equably inner core inside in water, thereby avoid low speed and high speed resonance point effectively, resonance noise during drying is less, thereby reaches higher using character, satisfy the instructions for use of quiet washing.
2, can take to dry rotating speed pointedly according to the eccentricity detecting result, drying degree and washing cleanliness factor are all higher.
