In order to solve the problem that the existing washing machine for dewatering only has one swing curve and cannot select the swing curve according to different clothes materials, the embodiment provides a dewatering control method of the washing machine, the whole washing process of the washing machine comprises a washing process, a rinsing process and a dewatering process, the dewatering process comprises a load swing stage, and the washing machine is controlled to swing the load according to the swing curve in the load swing stage so that the load meets the condition of high-speed dewatering, and the control method of the washing machine comprises the following steps:
and after the dehydration process is started, acquiring the weight information of the load, selecting a leveling curve according to the load material information when the weight of the load is greater than or equal to the set weight, and controlling the washing machine to level the load according to the selected leveling curve.
The control flow chart shown in fig. 1 includes the following steps:
s1, after the dehydration process is started, the motor reads the load weight l oad value through a weighing command;
s2: judging the value of l oad and the weight threshold value l oad 1;
s3: when the load weight l oad value is greater than or equal to the set weight, namely greater than or equal to a weight threshold l oad1, intelligently identifying the material of the clothes; the identification mode of the clothes material can be judged by intelligent visual equipment or physical quantity such as water absorption rate.
S4: selecting a leveling curve which is most suitable for the current clothes material according to the clothes material;
s5: and carrying out the leveling treatment on the clothes according to the selected leveling curve.
Further optionally, the selecting a balancing curve according to the load material information includes
The method comprises the steps of obtaining load material information, determining a balance parameter under the current load material information according to a preset corresponding relation between the load material information and the balance parameter, and selecting a balance curve according to the determined balance parameter.
Specifically, the swing curve includes different swing parameters, such as washing speed, acceleration, and holding time. In this embodiment, a preset corresponding relationship is selected by corresponding the material to one or more of the leveling parameters, and after the load material is determined, the leveling curve is selected according to the leveling parameters corresponding to the load material.
Further alternatively, as shown in fig. 3, the load leveling stage includes a first speed-up process and a first uniform speed process, which are sequentially performed, and the washing tub rotates in a first rotation direction in the first speed-up process and the first uniform speed process; the washing barrel in the first speed increasing process is increased from a static state to a rotating speed n1 at an acceleration a1, the washing barrel in the first constant speed process operates at a constant speed of n1, and the total operation time of the first speed increasing process and the first constant speed process is t 1; the preset corresponding relation between the load material information and the balance parameter comprises the following steps: the method comprises the following steps that the preset corresponding relation between load material information and the acceleration a1 of the first acceleration process, the rotating speed n1 of the first constant speed process and the total running time t1 of the first acceleration process and the first constant speed process is achieved.
Specifically, the target rotating speed n1 of the first acceleration process is adjusted through a test mode according to various loads at the early stage of the leveling stage, and the optimal despining leveling curves of different load types are found out through the acceleration a1, the first acceleration process and the total running time t1 of the first uniform speed process. Moreover, a large number of experiments prove that the clothes cannot be fully dispersed due to too short t1, so that the clothes are easy to agglomerate and adhere to the wall in the acceleration process; however, the excessively long t1 causes the clothes to be loosened and then gradually rolled into balls, which is not beneficial to uniform dispersion, and the inventor has verified through a large amount of experiments that the time of selecting t1 is optimal when the time is 5-8 s. In addition, because the clothes are different in material and different in volume, weight and water absorption, different target rotating speed n1 and acceleration a1 need to be set, the target rotating speed n1 is a state that the load is lifted to the half-barrel height and is fully loosened, and the acceleration a1 is a force for the load in the loosening state, so that the clothes can be attached to the wall quickly in the loosening state. Therefore, after the load type is known, the system automatically selects the optimal swing curve, and the dewatering efficiency is higher than that of a swing program which only uses a single swing curve.
Further optionally, as shown in fig. 3, the load leveling phase further comprises a second acceleration process in which the washing tub is accelerated from the rotation speed n1 to the rotation speed n2 at an acceleration a 2; the preset corresponding relationship between the load material information and the balance parameter further comprises: the load texture information corresponds to a predetermined relationship with the acceleration a2 of the second acceleration process. The second acceleration causes the continuously rolling load to spread evenly by imparting an acceleration to the load.
Further optionally, as shown in fig. 3, the load leveling stage further includes a second constant speed process, where the load is subjected to eccentricity detection in the second constant speed process, and when the detected eccentricity value meets a high-speed dehydration condition, the washing tub is controlled to perform high-speed dehydration at a dehydration rotation speed corresponding to the current load weight.
Specifically, in the present embodiment, the eccentric ranges in which dehydration can be performed are different in different load weight ranges, and the present embodiment determines whether the detected eccentric value satisfies the high-speed dehydration condition by selecting a preset corresponding relationship between the load weight range and the eccentric range in advance, and determining the eccentric range corresponding to the weight range according to the weight range in which the load weight is located after the load weight is determined. And meanwhile, different eccentric range gears are arranged in an eccentric range capable of dehydrating under the same load weight, each eccentric range gear corresponds to a high-speed dehydration rotating speed value, after the current load weight meets a high-speed dehydration condition, the eccentric range gear is determined according to the eccentric value obtained in the second uniform speed process, the high-speed dehydration rotating speed under the current load weight is determined according to the determined eccentric range gear, and the washing barrel is controlled to be accelerated to the dehydration rotating speed for high-speed dehydration. In the embodiment, when the eccentric detection is carried out at the second constant speed stage, the load weight is obtained again to further determine the load, and whether the high-speed dehydration condition is met or not is determined according to the second weighing result, so that the accuracy of the high-speed dehydration occasion is ensured, and the barrel collision phenomenon in the high-speed dehydration process caused by the weighing error is avoided.
Further optionally, as shown in fig. 3, the load leveling phase further comprises an unwinding process of controlling the washing machine to rotate at a rotation speed n3 for a time t2, the unwinding process wherein the washing tub rotates in a second rotation direction, the second rotation direction being opposite to the first rotation direction; and when the detected eccentricity value does not meet the high-speed dehydration condition, controlling the washing machine to enter a disentangling process after the speed is reduced. The preset corresponding relationship between the load material information and the balance parameter further comprises: the load material information corresponds to the rotation speed n3 of the unwinding process and the unwinding duration t 2. In the embodiment, the load is unwound by rotating forwards and backwards, and the unwinding process time or rotating speed of the load made of different materials may be different.
Further alternatively, when the eccentricity value obtained in the second uniform speed stage does not satisfy the high-speed dewatering condition, the spinning process is started after the speed is reduced to 0, and the spinning is stopped for a period of time after the speed of the washing tub is reduced to 0, as shown in fig. 3, the spinning stop time is t3, that is, the spinning process is started after the speed of the washing tub is reduced to 0 and the spinning process is stopped for t 3.
Further optionally, the leveling parameters in the leveling curve include general parameters and adjustable parameters, the general parameters are irrelevant to the load material, and the value of the load material is not changed. After the optimal dehydration curve under each load is found out through experiments, the curve parameter distribution table is completed, so that the curve parameters corresponding to the clothes material are selected after the clothes are identified, and the dehydration efficiency is improved.
As shown in FIG. 3, the acceleration of the second acceleration process, the duration t5 of the second acceleration process and the second uniform velocity process, the deceleration acceleration b1 for decelerating from the second uniform velocity process to 0 rpm, the deceleration time t2, etc. the adjustable parameters are selected according to the material of the load, r the acceleration a1 of the first acceleration process, the rpm n1 of the first uniform velocity process, the duration t1 of the first acceleration process and the first uniform velocity process, and the rpm n2 of the unwinding process and the duration t2 of the unwinding process, etc. The general parameters in the balance curve are shown in the table I, and the corresponding relation between the adjustable parameters in the balance curve and the load material is shown in the table II.
