The problem that the existing washing machine cannot guarantee the dewatering effect by dewatering for a preset length of time is solved. The embodiment provides a clothes treatment device and a dehydration control method and device thereof. The laundry treating apparatus includes a pulsator washing machine, a drum washing machine, and the like, and in the present embodiment, the laundry treating apparatus is preferably a pulsator washing machine. To further illustrate the technical solution of the present invention, first, a laundry treating apparatus according to an embodiment of the present invention will be described with reference to fig. 1.

Referring to fig. 1, the laundry treating apparatus is provided with an inner tub 3 and an outer tub 4, a water level probe 9 is provided at a tub bottom of the outer tub 4, and a conduction state of the water level probe 9 represents a dehydration state of laundry in the tub. In addition, the laundry treating apparatus further includes: the device comprises a controller 1, a balance ring 2, a wave wheel disc 5, a motor 6, a base 7, a drain pipe arranged at the bottom of an outer barrel 4, a drain valve 8 arranged on the drain pipe, a water level sensor 10, a water inlet pipe, a water inlet valve 11 and a top cover 12. In addition, the laundry treating apparatus is further provided with a display module.
The dehydration control method according to the present embodiment will be described below with reference to the drawings.
Fig. 2 is a flowchart illustrating a dehydration control method of a laundry treating apparatus according to an embodiment of the present invention. Fig. 3 is a schematic control logic diagram illustrating a dehydration control method of a laundry treating apparatus according to an embodiment of the present invention. Referring to fig. 2 and 3, the dehydration control method includes steps S1 to S3, in which:
s1, in a dehydration stage, primarily judging whether clothes in a drum are dehydrated completely according to the conduction state of a water level probe;
s2, when the clothes in the drum are judged to be dehydrated completely, judging whether the clothes in the drum are dehydrated completely or not by combining the motor operation parameters;
and S3, when the clothes in the drum are judged to be dehydrated completely, controlling a motor of the clothes treatment equipment to stop rotating, and finishing the dehydration.
The dehydration control method adopts a mode of combining the water level probe and the control program to judge the dehydration condition of clothes in the drum, namely firstly using the conduction state of the water level probe to primarily judge the dehydration condition, and then combining the motor operation parameters to assist in judging the drying, so that the accuracy of drying judgment results is increased, the dehydration time can be flexibly adjusted, and the unnecessary power consumption is reduced to a certain extent while the dehydration effect is ensured.
Specifically, after the laundry treating apparatus enters the dehydration stage from the washing process, the controller 1 controls the drain valve 8 to drain water, and then enters the dehydration stage after the drainage is completed. In the dehydration stage, the controller 1 drives the motor 6 to perform dehydration, the rotation speed of the motor will rise to the dehydration rotation speed V, and then the water level probe 9 is started to detect the water amount in the outer barrel 4. Considering that the inner barrel 3 is inclined when the clothes processing equipment dehydrates, the state of the probe is independently used for judging the dehydration condition, and errors exist, so that a motor acceleration process is added for assisting in judging the dryness, and the accuracy of a dryness judgment result is improved. When the water level probe 9 is judged not to have a water surface, the program enters a motor acceleration auxiliary judgment process, namely, whether clothes in the barrel are completely dehydrated is judged according to the rotating speed of the motor, and the purpose is to ensure the accuracy and reliability of judgment of the dehydration state of the clothes in the barrel.
Further optionally, step S1 includes steps B1, B2, wherein:
b1, when the water level probe is conducted, the clothes in the cylinder are not dehydrated completely;
and B2, if the water level probe is monitored to be continuously not conducted within the preset time, primarily judging that the clothes in the drum are completely dehydrated.
Specifically, when the water level probe 9 is turned on, that is, the water level probe 9 has a water surface, it is considered that the clothes in the drum are not dehydrated completely; if it is monitored that the water level probe 9 is continuously not conducted within the preset time, namely, the water level probe 9 has no water surface, it can be preliminarily judged that the clothes in the barrel are completely dehydrated at the moment.
Further optionally, with reference to fig. 4, the laundry treating apparatus is provided with a probe detection phase, and step S1 includes S11 to S14, wherein:
s11, executing a probe detection stage to judge whether the water level probe is conducted or not;
s12, when the water level probe is judged to be not conducted for the first time, ending the probe detection stage and timing;
s13, when the timing duration reaches a first preset duration, executing the probe detection stage again;
and S14, when the water level probe is judged to be not conducted again, the clothes in the drum are judged to be completely dehydrated.
Specifically, the laundry treating apparatus is provided with a probe detecting stage, and in the present embodiment, it is preferable to perform the probe detecting stage after the motor speed is increased to the dehydration speed V in the dehydration stage, that is, the probe detecting stage is generally performed while dehydrating to judge whether the water level probe is turned on in real time. When the probe in the barrel is detected to be not conducted for the first time, timing a first preset time ts, giving a waiting time for accumulated water flow on the barrel wall, not executing the probe detection stage at the moment, executing the probe detection stage again after the timing is finished, detecting the probe state to increase the judgment accuracy, judging that the probe in the barrel is not on the water surface if the probe is not conducted for the second time, and entering a motor acceleration auxiliary judgment flow by a program.
Further optionally, the step S11 of performing a probe detection stage includes S111 to S112, where:
s111, monitoring state information of the water level probe;
and S112, when the state information of the water level probe is preset information, the water level probe is regarded as not conducting.
Specifically, the water level probe status information may be a high-low level signal, for example, when receiving a high level signal from the water level probe 9, the water level probe 9 is considered to be on, and when receiving a low level signal from the water level probe 9, the water level probe 9 is considered to be off.
Further optionally, the motor operation parameter includes a motor rotation speed, and the determining whether the laundry in the drum is completely dehydrated in step S2 by combining the motor operation parameter includes:
controlling the motor to accelerate for multiple times at the same starting current, the same initial rotating speed and the same target rotating speed, and recording the acceleration time for each acceleration of the motor;
and judging whether the dehydration is clean or not according to the acceleration time of the motor for multiple times of acceleration.
Specifically, the motor operation parameters include motor rotation speed, current, voltage and the like, and taking the motor rotation speed as an example, the motor is controlled to accelerate for multiple times by using the same starting current, the same initial rotation speed and the same target rotation speed, and the acceleration time used by the motor for each acceleration is recorded; and judging whether the dehydration is clean or not according to the acceleration time of the motor for multiple times of acceleration. Namely, whether the clothes in the drum are completely dehydrated is judged according to the acceleration state of the motor.
Further optionally, at least two consecutive acceleration operations are interposed with a dewatering operation. Preferably, the dewatering operation is inserted in every two adjacent acceleration operations.
Specifically, the dehydration operation: the motor is controlled to rotate for a certain time at the dehydration rotating speed V so as to change the weight of the clothes in the barrel as much as possible, thus the accuracy and reliability of judging the dehydration state of the clothes in the barrel can be ensured.
Further optionally, with reference to fig. 5, the motor operation parameter includes a motor rotation speed, and the step S2 of determining whether the laundry in the drum is completely dehydrated with reference to the motor operation parameter includes steps S21 to S22, where:
s21, controlling the rotation speed of the motor to accelerate from the first rotation speed to the second rotation speed twice, and correspondingly recording the first acceleration duration and the second acceleration duration;
and S22, judging whether the clothes in the drum are completely dehydrated according to the first acceleration time length and the second acceleration time length.
Specifically, when the motor 6 is driven to accelerate at the same starting current, the time taken to accelerate to the same speed is different under different load conditions. Taking this as a starting point, the present embodiment provides a method for performing assisted intervention based on a motor acceleration process. Specifically, the rotating speed of the motor is controlled to be accelerated from a first rotating speed to a second rotating speed twice, the first acceleration duration and the second acceleration duration are correspondingly recorded, and whether the loads in the inner cylinder are the same or not can be reversely deduced by judging whether the two acceleration durations are equal or not; if the weight of the clothes in the drum is the same, the clothes in the drum are not scaled any more, namely the clothes are dehydrated completely; if the weight of the clothes in the drum is different, the clothes in the drum still change, namely, the dewatering clean state is not achieved. Namely, the dewatering time of the washing machine is flexibly adjusted by using the probe and the motor under the condition of double conditions, and unnecessary power consumption is reduced to a certain extent while the dewatering effect is ensured.
Specifically, the first rotation speed is preferably the dehydration rotation speed V.
Further optionally, with reference to fig. 6, step S21 includes S211 to S213, where:
s211, controlling the rotating speed of the motor to accelerate from a first rotating speed to a second rotating speed, and recording a first acceleration duration;
namely a primary motor acceleration process;
s212, controlling the rotating speed of the motor to be reduced to the first rotating speed, and controlling the motor to operate at the first rotating speed for a second preset time;
s213, controlling the rotating speed of the motor to accelerate to a second rotating speed, and recording a second acceleration duration;
namely the secondary motor acceleration process.
Specifically, the dewatering time tx (namely the second preset time length) is introduced before the secondary motor accelerates, so that the weight of clothes in the barrel is ensured to be changed as much as possible; the step of introducing the rotating speed of the motor before the acceleration of the secondary motor ensures the initial speed condition of the motor acceleration and the comparability of the front and rear acceleration time; therefore, the accuracy and the reliability of judging the dehydration state of the clothes in the drum are ensured.
Further optionally, step S22 includes steps A1 to A3, wherein:
a1, judging whether a difference value between a first acceleration duration and a second acceleration duration is smaller than or equal to a preset value; if yes, executing A2; if not, executing A3;
a2, judging that the clothes in the drum are completely dehydrated;
and A3, redetermining the first acceleration duration and the second acceleration duration and executing the step A1 by the redetermined first acceleration duration and second acceleration duration.
Specifically, after the first acceleration time period t1 and the second acceleration time period t2 are obtained, the first acceleration time period t1 and the second acceleration time period t2 are subtracted to obtain an acceleration time difference dt, and then the difference dt is compared with a reference value dts (namely, a preset value). When the acceleration time difference td is less than or equal to the reference value dts, the weight of the clothes in the barrel is not changed at the moment, the clothes in the barrel are judged to be dehydrated completely, and the motor is controlled to stop rotating at the moment to finish the dehydration; if dt is larger than the reference value dts, the weight of the clothes in the barrel is still changed at the moment, the clothes in the barrel are judged to be not completely dehydrated, the first acceleration time length and the second acceleration time length are determined again, and the judgment step A1 is repeated according to the newly determined first acceleration time length and the newly determined second acceleration time length until dt is smaller than or equal to dts.
The reference value dts of the acceleration time difference is a value close to 0, and the rotation speed detection of the motor during operation has fluctuation, so that the acceleration time difference dts is introduced and is used for compensating the time fluctuation caused by the rotation speed fluctuation; the dehydration of the time tx is inserted into the two detection starting current values in the front and the back, and the purpose is to ensure the accuracy and the reliability of the judgment of the dehydration state of the clothes in the barrel.
Further optionally, step A3 comprises:
a31, assigning the second acceleration duration to the first acceleration duration to obtain a new first acceleration duration;
a32, controlling the rotating speed of the motor to be reduced to the first rotating speed, and controlling the motor to operate at the first rotating speed for a second preset time period;
a33, controlling the rotation speed of the motor to accelerate to a second rotation speed, and recording a new second acceleration duration;
step A1 is performed with the new first acceleration period and the new second acceleration period.
Specifically, t2 is assigned to t1, the motor is controlled to be decelerated to V1 to dewater for tx time, then the motor acceleration time t2 is obtained again, and the steps are repeated until dt is smaller than or equal to dts. Compared with the method for executing the motor acceleration flow twice again, the method for judging the dry state of the motor correspondingly obtains two new first acceleration time lengths and second acceleration time lengths, and the method for judging the dry state of the motor is more energy-saving and saves more time.
Further optionally, a dewatering step is provided in the middle of the process of controlling the rotation speed of the motor to accelerate from the first rotation speed to the second rotation speed twice.
The dehydration control method according to the present embodiment will be described in its entirety with reference to fig. 7.
