To further illustrate the technical solution of the present invention, the following specific examples are provided as shown in fig. 1 to 3.
In the present embodiment, there is provided a control method of a washing machine, the control method including:
s1, collecting the weight value of the load in the washing barrel and the eccentricity value of the washing barrel;
s2, calculating an eccentricity fitting value according to the weight value and the eccentricity value;

In the embodiment, the load in the washing barrel is weighed to obtain the weighing value, the weighing value is fitted with the detected eccentric value of the washing barrel to obtain the eccentric fitting value, the eccentric fitting value is used as a characteristic value for preliminarily judging whether the noise exceeds the limit, the characteristic value is compared with the preset fitting value obtained through an experiment, and the noise can be controlled relatively accurately by adjusting based on the comparison result. It should be noted that, in this embodiment, both the eccentric fitting value and the preset fitting value adopt a fitting manner, the fitting value is a target value obtained by fitting and regressing the eccentric value and the weighing value together, before the fitting value is not referred, the set limit value is made by making the eccentric value and the weighing value together, and a two-dimensional table is made.
Preferably, the adjusting of the load in controlling the washing tub includes: controlling the washing barrel to shake and disperse the load; and then controlling the washing barrel to swing the load to be flat.
In some optional manners, step S3 further includes:
calculating the current motor power according to the eccentric fitting value in the process of controlling the washing barrel to pre-dewater the load;
judging whether to dehydrate according to the current motor power, comprising the following steps: when the current motor power meets the corresponding preset motor power value, controlling the washing barrel to carry out dehydration treatment on the load; when the current motor power does not meet the corresponding preset motor power value, the washing barrel adjusts the load.
Preferably, the calculating the current motor power according to the eccentricity fit value includes: acquiring corresponding rotating speed according to the eccentric fitting value; and calculating the current motor power according to the corresponding rotating speed.
In a specific control manner when the preset fitting value is satisfied in this embodiment: when the eccentric fitting value satisfies the corresponding preset fitting value, controlling the washing tub to pre-dewater the load comprises:
when the eccentric fitting value is smaller than a first preset fitting value, controlling the washing barrel to increase to a first preset rotating speed for pre-dewatering;
when the first preset fitting value is smaller than or equal to the eccentric fitting value and smaller than or equal to the second preset fitting value, controlling the washing barrel to increase to a second preset rotating speed for pre-dewatering;

when the third preset fitting value is not more than the eccentric fitting value and not more than the fourth preset fitting value, controlling the washing barrel to be accelerated to a fourth preset rotating speed for pre-dewatering;
wherein the first preset rotating speed (rotating speed 1) > the second preset rotating speed (rotating speed 2) > the third preset rotating speed (rotating speed 3) > the fourth preset rotating speed (rotating speed 4).
Correspondingly, the motor power needs to be collected in the rotating speed rising process, and in one mode, the motor power can be collected and selected or calculated in the corresponding stage by matching with the division of the rotating speeds in different stages. For example, in the process of controlling the rising speed of the washing tub: and controlling the washing barrel to gradually increase the speed from a first preset rotating speed, a second preset rotating speed, a third preset rotating speed to a fourth preset rotating speed, and calculating the average power of the motor with the rotating speed of the washing barrel stabilized at the corresponding preset rotating speed in the gradual increasing process as the current motor power.

The preset fitting values in fig. 2 are divided into comparison intervals corresponding to the eccentric fitting values, and the corresponding relationship is as follows: first preset fit value oob1< second preset fit value oob2< third preset fit value oob 3< fourth preset fit value 00b 4; and on the premise of meeting the fitting value, the section of the fitting value reflected by the load during dehydration is accelerated to the corresponding dehydration rotating speed. Wherein the first preset rotating speed is greater than the second preset rotating speed, the third preset rotating speed is greater than the fourth preset rotating speed; oob1 for an eccentricity value mapped by a 200g eccentric mass, 00b2 for an eccentricity value mapped by a 500g eccentric mass, oob3 for an eccentricity value mapped by a 800g eccentric mass, and the like: oob4 may also be set in conjunction with the test and the corresponding noise national standard. The general first preset rotating speed is set as the highest rotating speed and is 1400rpm or above; the second preset rotation speed is generally 1000 rpm; the third preset rotating speed is generally 600 rpm; the fourth predetermined speed is typically 400 rpm.
In fig. 3, the power mean value first preset power p1< second preset power p2< third preset power p3< fourth preset power p 4; similarly, if the speed can be increased to the corresponding speed on the premise of meeting the corresponding fitting value, if the mean power exceeds the limit value during the period, the operation of re-dewatering or speed reduction is carried out, and if the power is within the limit value, the operation is finished at the speed. It should be noted that, for setting the power limit, a general P1 setting value is an average power collected by the eccentric mass 1100g at the rotation speed of 400rpm, and the power is corrected in consideration of actual conditions, and accordingly, P2, P3, and P4 are average powers of the eccentric masses 800g, 500g, and 200g at the rotation speeds of 600rpm,1000rpm, and 1400rpm, respectively, and the power values are corrected according to actual experimental study conditions.
It should be noted that, in this embodiment, it is preferable to divide the rotation speed 3 into two determination results to perform dehydration or re-shaking and balancing, that is, when the rotation speed is less than 3, the power P (b) is used to perform determination, when the rotation speed exceeds P (b), the operation is stopped and readjusted, and when the rotation speed does not exceed P (b), the corresponding rotation speed is directly used to perform dehydration, where P (b) includes powers P1 and P2; when the rotating speed is over 3, the judgment is carried out according to P (c), when the rotating speed is over P (c), the speed reduction operation is carried out, and when the rotating speed is not over, the dehydration is directly carried out, wherein P (c) comprises P3 and P4.
In some optional manners, calculating the average power of the motor at which the rotation speed of the washing tub is stabilized at the corresponding preset rotation speed as the current motor power includes: when the washing barrel rotates to the corresponding preset rotating speed, controlling the washing barrel to rotate at the corresponding preset rotating speed; and calculating the average power of the motor in the preset time before the motor rotates according to the corresponding preset rotating speed to be used as the current motor power.
In some optional manners, if the current motor power does not satisfy the corresponding preset motor power value, the adjusting the load by the washing tub includes: if the rotating speed of the washing tub is increased from 0 to a fourth preset rotating speed, the real-time power of the motor is used as the current motor power, and if the current motor power exceeds a fifth preset power P (a), the washing tub rotates reversely for a preset time after stopping rotating, then the swinging rhythm is carried out, and the step S1 is executed again.
It should be noted that: in the process of setting the preset fitting value, generally speaking, for the acquisition of the eccentricity data, the eccentricity values mapped by the same eccentricity under different weights are different, and researches show that the eccentricity values mapped by the eccentricity values under the same eccentricity state along with the increase of the load weight are reduced, so that the limit value needs to be set according to the eccentricity and the weighing value together during dewatering, and even if the eccentricity values are the same, the limit value fluctuates due to the change of weighing; the method comprises the steps of collecting an eccentric value and a weighing value mapped by single eccentricity under an empty barrel state and single eccentricity under uniform load, fitting the eccentric value and the weighing value through collected data, and fitting the eccentric value and the weighing value in a linearized state, wherein the mapped fitting values of the same eccentric block under the empty barrel and the uniform load are unique.
In the process of further setting the power limit value of the motor, the noise value of each eccentric block is collected in a semi-silencing laboratory in an empty barrel state at each rotating speed until the sound power of the noise is greater than the national standard or the enterprise standard, and the corresponding power is recorded at the same time. It should be noted that: each single eccentric block is referred to herein as a single eccentric block, i.e., the eccentric that can be tolerated by the machine from 100g onwards, typically 1200g or more; the effect of setting the limit value after the test measurement is carried out by utilizing the eccentric block is as follows: research shows that the larger the eccentricity is, the higher the rotating speed is, and the larger the noise generated by the machine is, so that the noise value of each rotating speed of each single eccentricity is collected, and a basis is provided for the limit value of the subsequent dehydration parameter. The arrangement mode of the eccentric blocks in the experiment is as follows: and placing the eccentric block at the front end of the inner cylinder, and lifting the middle position of the rib.
And then according to the data collection of the noise level of the sound power, carrying out the limit value of the dehydration parameter at the rotating speed which is adaptive to the eccentric value allowed by the critical noise value, and simultaneously carrying out the maximum power limitation on each rotating speed according to the output of the power.
Exemplary embodiments of the present disclosure are specifically illustrated and described above. It is to be understood that the present disclosure is not limited to the precise arrangements, instrumentalities, or instrumentalities described herein; on the contrary, the disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
