[0037] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be more comprehensive and complete and fully convey the concept of the example embodiments to those skilled in the art.

[0038] like Figure 1 As shown, the present application provides a dehydration control method for a washing machine, the washing machine comprising: a dehydration module for dehydrating clothes; a water content detection module for detecting the water content of the clothes; the method comprises S110 to S140:

[0039] S110, controlling the dehydration module to accelerate to a preset rotation speed at an acceleration lower than a preset threshold value for pre-dehydration.

[0040] Specifically, the acceleration of the dehydration module refers to the linear speed of the inner drum of the washing machine. The preset threshold can be set to within 20% of the acceleration of the dehydration module when it is running at high speed. For example, the acceleration of the dehydration module when it is running at high speed is 3600m / s 2 , then the preset threshold can be set to 600m / s 2 、700m / s 2 or 720m / s 2 It should be understood that the acceleration during pre-dehydration is low acceleration compared to the acceleration during high-speed operation of the dehydration module, and the specific preset threshold value can be set manually or determined according to the current dehydration status of the dehydration module.

[0041] The preset speed is a low speed during pre-spinning. The preset speed may be a speed within a set range. The corresponding preset speed may also be determined based on the type or weight of the clothes.

[0042] Pre-dehydration is a preparatory dehydration step in the dehydration process, and is a stage for preparing for subsequent dehydration. In the period of time before pre-dehydration, the acceleration and rotation speed of the dehydration module are zero. Therefore, when pre-dehydration is performed, the dehydration module is controlled to accelerate to a preset rotation speed at an acceleration lower than a preset threshold value to avoid excessive instantaneous acceleration of the dehydration module, causing damage to the dehydration device, and the clothes can also be dehydrated appropriately so that part of the water in the clothes is removed, so as to facilitate the subsequent detection of the current water content of the clothes. It should be understood that when pre-dehydration is performed, the drainage pump of the washing machine is controlled to be closed so as to collect the water removed by the pre-dehydration of the clothes.

[0043] S120: After the pre-dehydration is performed for a first period of time, the current moisture content of the clothes is detected by a moisture content detection module.

[0044] Specifically, the current water content refers to the water content at the current moment. After the pre-dehydration is performed for a first period of time, part of the water absorbed by the clothes is removed, and at this time, the current water content of the clothes is detected by the water content detection module, so as to subsequently determine the corresponding dehydration parameters according to the current water content of the clothes.

[0045] In one embodiment of the present application, detecting the current moisture content of clothing includes: detecting a current water level frequency corresponding to the clothing; the current water level frequency is the parallel resonant frequency of the inductor and capacitor in the moisture content detection module at the current moment; and determining the current moisture content corresponding to the current water level frequency based on a mapping relationship between the water level frequency and the moisture content.

[0046] Specifically, the detection circuit of the water content detection module includes an inductor and a capacitor connected in parallel. The parallel resonant frequency of the inductor and the capacitor decreases as the water level increases and increases as the water level decreases. That is to say, the parallel resonant frequency is used as the water level frequency to characterize the water content. Therefore, the mapping relationship between the water level frequency and the water content can be determined in advance, so the current water level frequency can be detected during dehydration to determine the current water content of the clothes.

[0047] In another embodiment, detecting the current moisture content of clothing includes: detecting a current water pressure corresponding to the clothing; the current water pressure is the water pressure detected in a moisture content detection module at the current moment; determining a current water level according to the water pressure; and determining a current water content corresponding to the current water level according to a mapping relationship between the water level and the moisture content.

[0048] Specifically, there is a corresponding relationship between the water pressure and the water level. For the same position in the water storage container, the higher the water level, the greater the corresponding water pressure at that position; the lower the water level, the smaller the water pressure at that position. Therefore, the mapping relationship between the water level and the water content can be determined in advance, thereby determining the water content corresponding to the water level.

[0049] S130: When the current water content is greater than the first water content, obtain a dehydration parameter corresponding to the current water content.

[0050] Specifically, the first water content is the set minimum water content of the clothes after dehydration. The dehydration parameter refers to the parameter for controlling the dehydration module to perform dehydration. When the current water content is greater than the first water content, it means that the current water content of the clothes does not meet the preset conditions and still needs to be dehydrated. Therefore, the dehydration parameter corresponding to the current water content is obtained so that the dehydration module can be accurately controlled to perform dehydration according to the dehydration parameter.

[0051] In one embodiment of the present application, the dehydration parameters include dehydration time, dehydration speed and dehydration curve; obtaining the dehydration parameters corresponding to the current water content includes: obtaining the clothing type of the clothing; inputting the clothing type and the current water content into the machine learning model to obtain the dehydration time, dehydration speed and dehydration curve corresponding to the current water content; the dehydration curve is used to represent the change of acceleration of the dehydration module over time.

[0052] Specifically, the dehydration speed is the speed at which the dehydration module is controlled to dehydrate the clothes. It should be understood that since the instantaneous increase in speed of the dehydration module is likely to damage the components of the washing machine, before the dehydration module is controlled to reach the dehydration speed, the speed of the dehydration module can be gradually increased. Then it takes a certain amount of time to control the dehydration module to reach the dehydration speed, and the time spent in the speed increase process can be determined by the dehydration curve.

[0053] like Figure 2 and Figure 3 As shown, at the second minute of a dehydration treatment, the dehydration curve is controlled to accelerate at 1900m / s 2 Accelerate, the dehydration speed corresponding to the dehydration module is 620 rpm; at the 4th minute, the dehydration curve is controlled to accelerate to 3600m / s 2 The dehydration module is accelerated, and the dehydration speed corresponding to the dehydration module is 1200 rpm. It can be seen that in this dehydration process, the speed of the dehydration module is increased to 1200 rpm for 4 minutes.

[0054] The dehydration time is the time for the dehydration module to run at the dehydration speed. Figure 3 As shown, the spin speed is 1200 rpm and the spin time is 6 minutes.

[0055] The types of clothing include down jackets, ordinary clothing, and silk clothing. Generally, down jackets absorb more water, so the corresponding dehydration time is longer or the dehydration speed is higher. For example, the dehydration time of down jackets is 6 minutes and the dehydration speed is 1200 rpm. For silk clothing that is easily damaged, the washing machine needs to be dehydrated in the gentle mode, so the corresponding dehydration speed of silk clothing is lower, for example, the dehydration time of silk clothing is 5 minutes and the dehydration speed is 600 rpm.

[0056] A machine learning model refers to a function model learned from data that can achieve a specific function. The machine learning model in this application can be one of the learning models such as supervised learning, unsupervised learning, regression algorithm, artificial neural network, and deep learning, or a combination of multiple models. The machine learning model in this application can continuously correct the dehydration time, dehydration speed, and dehydration curve to make the water content of the clothes after dehydration lower without damaging the clothes and reducing the noise of the washing machine.

[0057] S140: Based on the dehydration parameters corresponding to the current water content, control the dehydration module to dehydrate the clothes.

[0058] Specifically, the dehydration parameters may include the dehydration time and the dehydration speed corresponding to each moment; the dehydration parameters are changed accordingly according to the water content of the clothes. Then, the dehydration module is controlled to dehydrate the clothes based on the dehydration parameters, that is, the dehydration is accurately performed according to the current water content of the clothes, rather than dehydrating the clothes according to fixed dehydration parameters in all cases, so that the clothes are in a state of very little water after the dehydration process, which is conducive to the subsequent drying of the clothes.

[0059] In the technical solution of the present application, the dehydration module is controlled to accelerate to a preset speed at an acceleration lower than a preset threshold for pre-dehydration, which can avoid the instantaneous over-acceleration of the dehydration module, causing damage to the dehydration device, and can also moderately dehydrate the clothes so that part of the water in the clothes is removed, so as to facilitate the subsequent detection of the current water content of the clothes; after the pre-dehydration is performed for a first period of time, the current water content of the clothes is detected by the water content detection module; when the current water content is greater than the first water content, the dehydration parameter corresponding to the current water content is obtained; based on the dehydration parameter corresponding to the current water content, the dehydration module is controlled to dehydrate the clothes, and the dehydration process can be accurately performed according to the current water content of the clothes, avoiding the dehydration module always dehydrating the clothes at the highest speed to generate a large noise. The present application can also make the clothes after dehydration in a state of very little water, which is conducive to the subsequent drying of the clothes.

[0060] In one embodiment of the present application, the dehydration parameters include dehydration time, dehydration speed and dehydration curve; the dehydration curve is used to indicate the change of acceleration of the dehydration module over time; based on the dehydration parameters corresponding to the current water content, the dehydration module is controlled to dehydrate the clothes, including: controlling the dehydration module to accelerate to the dehydration speed with a preset acceleration, and running the dehydration time at the dehydration speed to dehydrate the clothes.

[0061] Specifically, the preset acceleration is the acceleration corresponding to each moment determined according to the dehydration curve. Figure 2 As shown, at the second minute of the dehydration process, the preset acceleration a1 is equal to 1900 m / s 2 ; At the 4th minute of the dehydration process, the preset acceleration a2 is equal to 3600m / s 2 . Correspondingly, Figure 3 As shown, the dehydration module is controlled to gradually accelerate to 1200 rpm, and runs at this dehydration speed for 6 minutes to dehydrate the clothes.

[0062] In one embodiment of the present application, after controlling the dehydration module to dehydrate the clothes based on the dehydration parameters corresponding to the current moisture content, the method further includes: obtaining the number of dehydration times performed by the dehydration module; when the number of dehydration times is less than or equal to the preset number, returning to the step of detecting the current moisture content of the clothes through the moisture content detection module.

[0063] Specifically, when the current water content of the clothes is detected for the first time and the dehydration parameters are determined, the dehydration module is controlled to perform dehydration according to the dehydration parameters, and the number of dehydration times is once. When the current water content of the clothes is detected for the second time and the new dehydration parameters are determined, the dehydration module is controlled to perform dehydration according to the new dehydration parameters, and the number of dehydration times is twice. For example, the number of dehydration times can be set to three times. When the preset number of times is less than or equal to three times, the current water content of the clothes can be detected again, and then it is determined whether the clothes need to be dehydrated according to the current water content of the clothes.

[0064] In one embodiment of the present application, the washing machine also includes: a drying module for drying clothes; after obtaining the number of dehydration times of the dehydration module, the method provided in the present application also includes: when the number of dehydration times is greater than the preset number, controlling the dehydration module to end the dehydration process, and controlling the drying module to dry the clothes.

[0065] Specifically, if only the moisture content threshold of the clothes after dehydration is set, but the dehydration number threshold is not set, then the current moisture content of the clothes may not be less than the moisture content threshold, causing the dehydration module to repeatedly dehydrate, resulting in energy waste. In order to solve this problem, when the number of dehydration times is greater than the preset number, the dehydration module is controlled to end the dehydration process, and the washing machine is controlled to enter the next step, such as controlling the drying module to dry the clothes or controlling the washing machine to send a reminder to the user. For example, the preset number can be set to three times. If the user selects the "dry clothes" function, after the dehydration number reaches four times, the dehydration module is controlled to end the dehydration process, and the drying module is controlled to dry the clothes.

[0066] In one embodiment of the present application, before controlling the dehydration module to accelerate to a preset speed at an acceleration lower than a preset threshold for pre-dehydration, the method further includes: in response to an instruction to dehydrate the clothes, controlling the washing machine to pre-drain; detecting the current water content of the clothes by a water content detection module; when the current water content is less than a second water content, controlling the pre-drainage to continue for a second time period.

[0067] Specifically, the instruction to dehydrate clothes may be issued by the function selected by the user. For example, if the user selects the "wash and dry" function, the clothes need to be dehydrated before being dried. It may also be issued by the user selecting the "dehydration" function alone. It may also be a dehydration instruction generated by the washing machine during the automatic washing of clothes.

[0068] Pre-drainage refers to draining the water in the washing machine that has not been absorbed by the clothes. When pre-draining, the drainage pump of the washing machine is controlled to open so that the water in the washing machine is drained out of the machine body.

[0069] The second moisture content is the moisture content of the clothing when it has fully absorbed water, wherein fully absorbing water means that the moisture absorbed by the clothing is a preset percentage of its own weight. For example, for a 100g clothing, when the moisture absorbed by the clothing is 85% of its own weight, that is, the total mass of the clothing after absorbing water is 185g, the clothing is considered to be in a state of fully absorbing water.

[0070] The second duration can be fixed to any duration, for example, the second duration is 30 seconds. Then when the current water content is less than the second water content, the pre-drainage is controlled to continue for 30 seconds. The second duration can also be determined according to the current weight and initial weight of the clothes. For example, when the initial weight of the clothes is 1kg and the current weight is 2.3kg, the second duration increases by 10 seconds for every 1kg increase in the difference between the current weight and the initial weight. Then the second duration at this time is (2.3-1)×10=13 seconds. Then when the current water content is less than the second water content, the pre-drainage is controlled to continue for 13 seconds.

[0071] like Figure 4As shown, a dehydration control device for a washing machine is provided, the washing machine comprises: a dehydration module for dehydrating clothes; a water content detection module for detecting the water content of clothes; the device comprises:

[0072] The pre-dehydration unit 410 is used to control the dehydration module to accelerate to a preset speed at an acceleration lower than a preset threshold value for pre-dehydration;

[0073] The water content detection unit 420 is used to detect the current water content of the clothes through the water content detection module after the pre-dehydration is performed for a first period of time;

[0075] The dehydration control unit 440 is used to control the dehydration module to dehydrate the clothes based on the dehydration parameters corresponding to the current water content.

[0076] In one embodiment of the present application, the moisture content detection unit 420 is used to detect the current water level frequency corresponding to the clothes; the current water level frequency is the parallel resonant frequency of the inductor and capacitor in the moisture content detection module at the current moment; according to the mapping relationship between the water level frequency and the moisture content, the current moisture content corresponding to the current water level frequency is determined.

[0077] In one embodiment of the present application, the device also includes: a number control unit, which is used to obtain the number of dehydration times performed by the dehydration module after controlling the dehydration module to dehydrate the clothes based on the dehydration parameters corresponding to the current water content; when the number of dehydration times is less than or equal to the preset number, return to the step of detecting the current water content of the clothes through the water content detection module.

[0078] In one embodiment of the present application, the washing machine also includes: a drying module for drying clothes; the number control unit is also used to control the dehydration module to end the dehydration process and control the drying module to dry the clothes after obtaining the number of dehydration times of the dehydration module and when the number of dehydration times is greater than a preset number.

[0080] In one embodiment of the present application, the dehydration parameters include dehydration time, dehydration speed and dehydration curve; the parameter acquisition unit 430 is used to obtain the type of clothing; the type of clothing and the current water content are input into the machine learning model to obtain the dehydration time, dehydration speed and dehydration curve corresponding to the current water content; the dehydration curve is used to represent the change of acceleration of the dehydration module over time.

[0082] The specific implementation of the dehydration control device of the washing machine provided in the present application has been explained in the corresponding dehydration control method of the washing machine, and will not be repeated here.

[0083] like Figure 5 As shown, the present application provides a washing machine 500, which includes: an inner drum for loading clothes; an outer drum, which is sleeved on the outside of the inner drum, and a drainage gap is defined between the inner drum and the outer drum; the washing machine 500 also includes: a dehydration module 510, which is used to dehydrate the clothes; a water content detection module 520, which is used to detect the water content of the clothes; a control module 530, which is connected to the dehydration module 510 and the water content detection module 520, and is used to implement the dehydration control method of the washing machine provided in any embodiment of the present application.

[0084] Specifically, in response to an instruction to dehydrate the clothes, the control module 530 controls the dehydration module 510 to accelerate to a preset speed at an acceleration lower than a preset threshold for pre-dehydration; after the pre-dehydration is performed for a first period of time, the control module 530 controls the moisture detection module 520 to detect the current moisture content of the clothes, and then the control module 530 determines the dehydration parameters according to the current moisture content, and then controls the dehydration module 510 to dehydrate the clothes with the corresponding dehydration parameters, and the moisture in the dehydration process is discharged from the washing machine through the drainage gap between the outer drum and the inner drum.
