Detailed Description

The application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present application are shown in the drawings.

Fig. 1 is a schematic flow chart of a clothes distribution method provided by the present application, which may be implemented by a clothes distribution device provided by the present application, where the device may be implemented in software and/or hardware. In a specific embodiment, the apparatus may be integrated in a laundry treatment device, for example, a washing machine, and the following embodiments will be described taking the integration of the apparatus in the laundry treatment device as an example. Referring to fig. 1, the method may specifically include the steps of:

step 101, if it is determined that the noise value in the noise detection stage meets the preset condition and the target rotation speed in the noise detection stage is greater than or equal to the preset rotation speed threshold, entering an eccentric value detection stage after the execution duration corresponding to the noise detection stage is executed.

Specifically, the preset rotation speed threshold is a preset threshold that can be reached by the rotation speed of the motor in the noise detection stage that is preset, and for example, the preset rotation speed threshold may be 400 rotations/minute. The preset condition is a condition that the preset laundry treating apparatus may enter the eccentricity value detection stage from the noise detection stage. The noise detection stage has a corresponding target rotation speed and execution duration, when the noise value in the noise detection stage meets the preset condition, the target rotation speed of the noise detection stage is determined, and when the target rotation speed at the time is greater than or equal to the preset rotation speed threshold value, the eccentric value detection stage is started after the execution duration corresponding to the noise detection stage is executed.

The preset rotation speed threshold value is 400 rpm, the corresponding execution time period in the noise detection stage is 2 minutes, the noise value in the noise detection stage is determined to meet the preset condition, and the target rotation speed in the noise detection stage is greater than or equal to 400 rpm, and the eccentric value detection stage is entered after the execution time period in the noise detection stage reaches 2 minutes.

Step 102, in an eccentricity value detection stage, a current eccentricity value when a laundry treating tub in a laundry treating apparatus rotates is obtained.

Specifically, in the eccentricity value detection stage, the current eccentricity value when the laundry treating tub in the laundry treating apparatus is rotated may be acquired through the driver in the laundry treating apparatus, and the current eccentricity value may also be acquired through the sensor in the laundry treating apparatus.

And 103, if the current eccentricity value is greater than or equal to the eccentricity value threshold value, subtracting a preset threshold value from the target rotating speed of the motor corresponding to the eccentricity value detection stage to serve as an initial rotating speed, and returning to the noise detection stage.

The noise detection stage comprises a first noise detection stage and a second noise detection stage.

Specifically, the target motor speed corresponding to the eccentricity value detection stage is a preset value, the initial motor speed corresponding to the eccentricity value detection stage is a target motor speed of the noise detection stage, the motor acceleration corresponding to the eccentricity value detection stage is a negative value, and for example, the target motor speed corresponding to the eccentricity value detection stage may be 100 rpm, and the initial motor speed corresponding to the eccentricity value detection stage is 400 rpm. After the current eccentric value is obtained, if the current eccentric value is greater than or equal to the eccentric value threshold, the fact that the eccentric value of the clothes treatment barrel in the clothes treatment equipment is higher at the moment is indicated, larger noise is generated when the dehydration operation is performed, the clothes are unevenly distributed, the dehydration efficiency is low, and therefore when the current eccentric value is greater than or equal to the eccentric value threshold, the noise detection stage is returned. At this time, the initial rotation speed corresponding to the noise detection stage is the rotation speed obtained by subtracting a preset threshold from the target rotation speed of the motor corresponding to the eccentricity value detection stage. For example, the preset threshold may be 50 revolutions per minute.

Optionally, if the current eccentricity value is greater than or equal to the eccentricity value threshold, subtracting a preset threshold from the motor target rotation speed corresponding to the eccentricity value detection stage to serve as an initial rotation speed of the first noise detection stage, and taking the motor target rotation speed corresponding to the eccentricity value detection stage as a target rotation speed of the first noise detection stage to return to the first noise detection stage.

Specifically, when the current eccentricity value is greater than or equal to the eccentricity value threshold, the first noise detection stage of the noise detection stages is returned. At this time, the initial rotation speed corresponding to the first noise detection stage is the rotation speed obtained by subtracting the preset threshold from the target rotation speed of the motor corresponding to the eccentric value detection stage, and the target rotation speed corresponding to the first noise detection stage is the target rotation speed of the motor corresponding to the eccentric value detection stage.

And 104, if the current eccentricity value is smaller than the eccentricity value threshold value, entering a dehydration stage after the execution time corresponding to the eccentricity value detection stage is completed.

Specifically, after the current eccentric value is obtained, if the current eccentric value is smaller than the eccentric value threshold, it is indicated that the eccentric value of the clothes treating barrel in the clothes treating apparatus is lower at the moment, no large noise is generated when the dewatering operation is performed, the clothes are uniformly distributed, and the dewatering efficiency is high, so that when the current eccentric value is smaller than the eccentric value threshold, the dewatering stage can be performed after the execution time corresponding to the eccentric value detection stage is performed.

specifically, according to the second noise value, whether the second noise value meets a preset condition is determined; and when the second noise value does not meet the preset condition, returning to execute the first noise detection stage. At this time, the initial rotation speed and the target rotation speed of the motor in the first noise detection stage are both the difference between the target rotation speed and the preset threshold in the second noise detection stage.

Optionally, if the second average noise difference is greater than or equal to the preset second difference threshold, or the second current noise difference is greater than or equal to the current noise standard threshold, it is determined that the second noise value does not meet the preset condition.

Specifically, after obtaining a second average noise difference value according to the difference between the second current average noise value and the first current average noise value, comparing the second average noise difference value with a preset second difference threshold, and if the second average noise difference value is greater than or equal to the preset second difference threshold, determining that the second noise value does not meet the preset condition. And when the second current noise difference value is larger than or equal to the current noise standard threshold value, determining that the second noise value does not meet the preset condition. In one possible embodiment, it may be determined that the second noise value does not satisfy the preset condition only by the second average noise difference value being greater than or equal to a preset second difference threshold; in another possible implementation manner, the second noise value may be determined to not meet the preset condition only by the second current noise difference value being greater than or equal to the current noise standard threshold, which is not limited by the present application.

Optionally, a total number of times the first noise detection phase is performed is determined.

Specifically, the total number of times of returning to the execution of the first noise detection stage is determined in an accumulated manner, and when the second noise value does not satisfy the preset condition, the value of the total number of times is determined.

For example, when the current second noise value does not satisfy the preset condition, the total number of times of returning to the first noise detection stage is determined to be 2 times.

Optionally, if the total number of times the first noise detection phase is returned to be performed is less than the preset number threshold, the first noise detection phase is returned to be performed.

Specifically, the preset number threshold is a preset total number of times of returning, and when the total number of times of returning to execute the first noise detection stage is smaller than the preset number threshold, the first noise detection stage is determined to be returned. Determining to return to the first noise detection stage when the total number of times the first noise detection stage is returned to be executed is less than a preset number threshold value can avoid returning to the reference detection stage each time, thereby saving the operation time of the laundry treatment apparatus.

Illustratively, the preset number of thresholds is 3 times, and the total number of times the first noise detection phase is returned to be performed is 2 times, which is less than the preset number of thresholds, at which time the control strategy of the motor is determined to be returned to the first noise detection phase.

Optionally, if the total number of times the first noise detection phase is performed is greater than or equal to the preset number threshold, the initial distribution phase is performed.

Wherein the initial distribution phase is a phase before the reference noise detection phase. The initial distribution stage comprises one or more distribution sub-stages, which are sequentially executed, and each distribution sub-stage corresponds to the initial rotation speed of the motor, the target rotation speed of the motor, the acceleration and the running time.

In each of the sub-stages, the motor starts rotating at a starting rotational speed and increases the rotational speed at a corresponding acceleration until a target rotational speed corresponding to the sub-stage is reached and continues rotating at the target rotational speed until a run time corresponding to the sub-stage is reached.

Specifically, when the total number of times of executing the first noise detection stage is greater than or equal to the preset number threshold, determining that the control strategy of the motor is to return to the initial distribution stage.

Illustratively, the preset number of thresholds is 3 times, and the total number of times the first noise detection phase is returned to be performed is 3 times, which is equal to the preset number of thresholds, at which time the control strategy of the motor is determined to be returned to the initial distribution phase.

As shown in the figure, the laundry treatment apparatus starts to perform laundry distribution at S1, S1 and S2 are initial distribution phases, S3 is a reference noise detection phase, S4 is a first noise detection phase, and enters a second noise detection phase S5 after running to an operation duration of S4 under the condition that the first noise value satisfies a preset condition, the starting rotation speed of S5 is a target rotation speed of S4, the motor rotation speed of S4 is increased by a preset threshold value as the target rotation speed of S5, and the laundry treatment apparatus runs to an operation duration of S5 under the condition that the second noise value satisfies the preset condition. And after the S5 reaches the target rotating speed, returning to the S6 second noise detection stage under the condition that the second noise value meets the preset condition, wherein the initial rotating speed of the S6 is the target rotating speed of the S5, the motor rotating speed of the S5 is increased by a preset threshold value to serve as the target rotating speed of the S6, and the operation time is long from the operation to the operation of the S6 under the condition that the second noise value meets the preset condition. The subsequent processes of S6 to S7, S11 to S12 and S12 to S13 are the same as those of S5 to S6, and the processes of S8 to S9, S10 to S11 are the same as those of S4 to S5, and will not be repeated here. And in the operation process of S7, the second noise value does not meet the preset condition, and the first noise detection stage of S8 is returned, wherein the motor rotation speed of S7 minus the preset threshold value is used as the starting rotation speed and the target rotation speed of S8, and the operation is performed until the operation time of S8 is met under the condition that the first noise value meets the preset condition. The processes of S9 to S10 are the same as those of S7 to S8, and will not be described again here. After the operation duration is satisfied in S13, the target rotation speed reaches the preset rotation speed threshold, so that the laundry machine enters the step S14 of detecting the eccentricity value, and performs the eccentricity value detection, and when the current eccentricity value is smaller than the eccentricity value threshold, the laundry machine enters the dehydration step after the execution duration corresponding to the eccentricity value detection step is executed.

It should be understood that, although the steps in the flowchart of fig. 2a are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders. Moreover, at least some of the steps in fig. 2a may comprise a plurality of sub-steps or phases, which are not necessarily performed at the same time, but may be performed at different times, the order of execution of which may not necessarily be sequential, but may be performed in rotation or alternatively with at least a portion of the sub-steps or phases of other steps or steps.
