All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, the present invention is a method for self-adjusting a dehydration curve according to a clothes state, comprising the following steps:
the washing machine is operated to shake off the laundry, after shake off, the laundry is subjected to eccentricity detection to obtain an eccentricity value UB, and the relation between the eccentricity value UB of the laundry and a set eccentricity threshold value is judged;
when the eccentricity UB is in positive correspondence with the set eccentricity threshold value, entering the next step, otherwise, shaking the clothes again, and judging the relation between the eccentricity UB of the clothes and the set eccentricity threshold value again;
the clothes are weighed to obtain a weight value I B, the size relation between the weight value I B and a set weight threshold is judged, the eccentric value UB of the clothes is compared with a dehydration threshold in size, and different dehydration curves are adjusted according to the ratio result.
The eccentric value detection adopts an eccentric sensor; the eccentric sensor is arranged at the bottom of the inner cylinder of the washing machine; and setting an eccentricity threshold K, wherein the relation between the eccentricity value UB of the clothes and the set eccentricity threshold is judged to be UB less than or equal to K, and if the relation is not less than the K, UB is more than K.
Specific numerical values are exemplified as follows: and if the data acquired by the eccentric sensor is more than 90rpm, the clothes are not qualified in eccentric weighing detection.
The detection of the weight value I B can adopt a pressure sensor, and for a drum washing machine, the pressure sensor can be arranged below a suspension system, the suspension system presses the pressure sensor under the action of the gravity of clothes, the stress information detected by the pressure sensor is fed back to an MCU of the washing machine, and the MCU judges the weight of the clothes; alternatively, the pressure sensor may be disposed above the suspension system, and the weight of the laundry is determined by the force information.
When judging the relation between the eccentric value UB of the clothes and the set eccentric threshold value, the judgment number between the eccentric value UB and the set eccentric threshold value is marked as S, and S=S+1, when the eccentric value UB and the set eccentric threshold value relation are in correspondence, the judgment number is judged before the clothes are shaken again, if S is less than or equal to S0, the clothes are shaken again, and if S is more than S0, the program is ended.
By judging the number of times of shaking and scattering of the clothes repeatedly, a set value for ending one cycle is set, when the number of times of shaking and scattering exceeds the set value for ending, the program is ended, and the clothes are abnormal, and even though the required eccentric value can not be reached through a plurality of times of cycles, the clothes are required to be checked manually to check whether the clothes which can not be shaken and scattered exist or not, so that the energy loss of the washing machine caused by a plurality of times of cycles is prevented.

In the second case, the eccentricity value UB is less than M, and the weighing value I B is more than N; if the judgment is that the state is not the case III; if yes, the pre-dewatering is carried out, after the pre-dewatering is finished, the eccentric value UB and the weighing value I B of the clothes are judged again, if the judgment result is that the clothes are subjected to high-speed dewatering, and after the high-speed dewatering is finished, the program is ended, if the judgment result is that the clothes are subjected to other conditions, the program is carried out, and the program is carried out in a corresponding flow, so that an optimal dewatering curve can be provided under the conditions of small eccentricity and large load.
In the third case, the eccentric value UB is more than M, the weighing value I B is less than N, if the weighing value is judged to be not less than the fourth case, the pre-dewatering is carried out, the eccentric value UB of the clothes is judged again after the pre-dewatering is finished, and the eccentric value UB is more than M1: if yes, entering secondary pre-dehydration, entering high-speed dehydration after the secondary pre-dehydration is finished, and ending the procedure after the high-speed dehydration is finished; if not, the high-speed dehydration is directly carried out, and the procedure is finished after the high-speed dehydration is finished, so that the optimal dehydration thought can be provided under the condition of large eccentricity and small load.
In case four, namely, when the eccentricity value UB is more than M and the weighing value I B is more than N, the washing machine directly enters pre-dewatering, and after the pre-dewatering is finished, the eccentricity value UB of the clothes is judged again, and the eccentricity value UB is more than M2 is judged: if yes, performing deviation correcting action; if not, the high-speed dehydration is carried out, and the procedure is finished after the high-speed dehydration is finished, so that the dehydration curve with the shortest time and highest efficiency can be provided under the condition of large eccentric and heavy load.
The correction action is specifically to carry out secondary dehydration on the clothes, judge the eccentricity UB of the clothes after the secondary pre-dehydration is finished, and judge the eccentricity UB to be more than M3: if yes, climbing to 500rpm to maintain the set dehydration time, and ending the procedure after the dehydration is completed; if not, the high-speed dehydration is performed, and the process is ended after the high-speed dehydration is completed.
