[0046] In order to be able to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The accompanying drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the sake of convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0047] The terms "first," "second," and the like in the technical solutions described in the embodiments of the present disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate to facilitate the description of the embodiments of the present disclosure herein. In addition, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions.

[0048] Unless otherwise stated, the term "plurality" means two or more.

[0049] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B means: A or B.

[0050] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0051] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0052] like Figure 1-1 、 Figure 1-2and Figure 1-3 As shown, the washing machine 100 includes: a control panel 1, which is arranged above the control panel base 3 and is used to display the working status of the washing machine and operate the washing machine. The inner drum 4 is cylindrical with an upper opening and is arranged inside the outer drum 5 at a set distance. The impeller 10 is a circular disk located in the center of the bottom of the inner drum 4. The impeller 10 is divided into four impeller areas, namely D1, D2, D3 and D4. The upper cover 2 is equipped with a camera light source 7 and a camera 8. The outer diameter of the camera light source 7 is smaller than the inner diameter of the inner drum 4. The camera light source 7 is mounted on the bottom of the upper cover 2 via four light source mounting brackets 6. The camera light source 7 can be kept horizontal with the inner drum 4 to provide sufficient shooting light for the camera 8. The camera 8 is mounted on the bottom of the upper cover 2 via a camera bracket 9. The camera 8 is slightly larger than the camera light source 7 in the longitudinal dimension and is used to capture images of each impeller area. During a spin cycle, uneven distribution of laundry within the drum can cause the washing machine to become eccentric, causing the outer drum to strike the safety switch, terminating the spin cycle and impacting the user experience. In related art, when the eccentricity detection value is less than or equal to the eccentricity protection value, the washing machine is controlled to execute a spin cycle. However, if the laundry within the drum is unevenly distributed, this can still lead to eccentricity activation failure. Ultimately, when the washing machine is controlled to execute a spin cycle again, the outer drum strikes the safety switch again, terminating the spin cycle and impacting the user experience. In the disclosed embodiment, eccentricity is detected based on the collected load mass of the pulsator area. If eccentricity is determined, the eccentric load area is determined based on the collected image of the pulsator area and the load mass. The washing machine is then controlled to execute corresponding operations based on the eccentric load area, ultimately completing the spin cycle. Different eccentric load areas correspond to different operations. Therefore, when eccentricity is detected, the operation corresponding to the eccentric load area can be executed to complete the spin cycle, reducing spin cycle anomalies caused by uneven laundry distribution, thereby improving the success rate of the spin cycle and enhancing the user experience.

[0053] The impeller is divided into several impeller areas such as Figure 2 As shown, the impeller is evenly divided into four sector-shaped impeller regions of equal area, D1, D2, D3, and D4, using multiple identical straight lines extending from the impeller axis to its periphery. Mass sensors G1, G2, G3, and G4 are installed in each sector to detect the load mass of each impeller region. Dividing the impeller into multiple impeller regions facilitates the acquisition of images and load mass for each impeller region.

[0054] Calculate the angle between the two impeller areas as Figure 3-1 and Figure 3-2 As shown in the figure, the washing machine rotates clockwise. Figure 3-1In the figure, D2 is the eccentric load area, and D1 is the preset starting area. The angle between the eccentric load area and the starting area is 270°. Figure 3-2 In the figure, D4 ​​is the eccentric load area, D1 is the preset starting area, and the angle between the eccentric load area and the starting area is 90°.

[0055] Combine Figure 4 As shown, an embodiment of the present disclosure provides a method for controlling dehydration of a washing machine, comprising:

[0056] S401, the washing machine detects eccentricity according to the load mass of each pulsator area.

[0057] S402: When the washing machine is eccentric, the eccentric load area is determined based on the collected images of each pulsator area and the load mass.

[0058] S403: The washing machine is controlled to perform corresponding operations according to the eccentric load area to complete dehydration.

[0059] The method for controlling the dehydration of a washing machine provided by the embodiment of the present disclosure can reduce dehydration abnormalities caused by uneven distribution of clothes, improve the success rate of dehydration of the washing machine, and enhance the user's product experience.

[0060] Optionally, detecting eccentricity based on the load mass of each pulsator area includes: collecting the load mass of each pulsator area; calculating the absolute difference in the load masses between adjacent pulsator areas to obtain multiple load mass absolute differences; and determining that the washing machine is eccentric when the sum of the multiple load mass absolute differences is greater than a first threshold. In this way, the eccentricity of the washing machine can be more accurately determined.

[0061] Optionally, the first threshold is set to an average value of the load masses of each pulsator area. In this way, it is possible to more accurately determine whether the washing machine is eccentric.

[0062] For example, the impeller is divided into 4 impeller areas, and the load mass of the 4 impeller areas is collected. Where i = 1, 2, 3, 4. If this is true, it is determined that the washing machine is eccentric.

[0063] Optionally, in the event of eccentricity, the eccentric load area is determined based on the collected images of each pulsator area and the load mass, including: performing image recognition on the collected images of each pulsator area to obtain the clothing coverage area of ​​each pulsator area; and determining the eccentric load area based on the load mass and clothing coverage area of ​​each pulsator area. In this way, the eccentric load area can be determined more accurately.

[0064] Optionally, determining the eccentric load area based on the load mass and clothing coverage area of ​​each pulsator area includes: within each pulsator area, using the pulsator area whose load mass meets a first condition as the relative mass area; and within each pulsator area, using the pulsator area whose clothing coverage area meets a second condition as the relative area area; and determining the eccentric load area based on the relative mass area and the relative area area. In this way, by identifying potential eccentric areas, the eccentric load area can be ultimately determined more accurately.

[0065] Optionally, determining the eccentric load region by using the relative mass region and the relative area region includes: determining the relative mass region as the eccentric load region when the third condition is satisfied. In this way, the eccentric load region can be determined more effectively.

[0066] Optionally, determining the eccentric load area by the relative mass area and the relative area area includes: determining the relative area area as the eccentric load area when the fourth condition is met. In this way, the eccentric load area can be determined more effectively.

[0067] Optionally, the first condition is that the ratio of the load mass to the load mass of other impeller regions is greater than or equal to a second threshold, wherein the second threshold is greater than 1. In this way, potential eccentric regions with larger load mass can be found more accurately.

[0068] Illustratively, the second threshold is 1.2, 1.3 or 1.4.

[0069] Optionally, the second condition is that the ratio of the clothing coverage area to the clothing coverage areas of other regions is greater than or equal to a third threshold, wherein the third threshold is greater than 1. In this way, potential eccentric regions with larger clothing coverage areas can be found more accurately.

[0070] Illustratively, the third threshold is 1.2, 1.3 or 1.4.

[0071] Optionally, the third condition includes: the presence of a relative mass region and the absence of a relative area region. In this way, the eccentric load region can be quickly found.

[0072] Optionally, the third condition includes: the relative mass region and the relative area region are the same region. In this way, the eccentric load region can be quickly found.

[0073] Optionally, the third condition includes: the relative mass zone and the relative area zone are different zones, and the washing mode is a large-load mode. This can be determined by determining whether the selected washing mode name contains the keywords "large capacity," "large load," "large item," or "large piece." Alternatively, the large-load mode can be determined by determining whether the sum of the load masses of each pulsator zone exceeds a fourth threshold. This allows for more accurate identification of potential eccentric load areas.

[0074] Illustratively, the fourth threshold is 10 kg, 20 kg or 30 kg.

[0075] Optionally, the fourth condition includes: there is no relative mass region, and there is a relative area region. In this way, the eccentric load region can be quickly found.

[0076] Optionally, the fourth condition includes: the relative mass region and the relative area region are different regions, and the washing mode is not a large load mode. In this way, the potential eccentric load region can be found more accurately.

[0077] Optionally, the pulsator is divided into a plurality of pulsator zones, and eccentricity is detected based on the load mass of each pulsator zone. If the sum of the absolute differences of the plurality of load masses is less than or equal to a first threshold, the method further comprises: executing a spin cycle. In this way, considering that no eccentricity has occurred, the spin cycle is retried, thereby ultimately completing the process of controlling the spin cycle of the washing machine.

[0078] Optionally, the eccentric load region is determined using the relative mass region and the relative area region. If the fifth condition is met, the method further includes: performing a rinse cycle; and after the rinse cycle is complete, performing a spin cycle. This allows for the possibility that no potential eccentric load region is found, and the process of controlling the spin cycle of the washing machine is completed by retrying the rinse cycle and then the spin cycle.

[0079] Optionally, the fifth condition includes: no relative mass region exists, and no relative area region exists. In this way, the absence of an eccentric load region can be determined more quickly.

[0080] Optionally, the washing machine is controlled to perform corresponding operations based on the eccentric loading area to complete dehydration, including: controlling the rotation of the pulsator to perform washing; wherein the rotation angle of the pulsator is determined based on the eccentric loading area; and performing dehydration after washing is completed. This ensures that the eccentric loading area is located in the preset starting area after each rotation cycle, making washing and dehydration easier.

[0081] Optionally, the rotation angle of the impeller is determined according to the eccentric load area, including: calculating ω2=β+ω1 to obtain the rotation angle ω2 of the impeller; wherein β is the angle between the eccentric load area and the preset starting area, and ω1 is the set rotation angle.

[0082] For example, the preset rotation angle is set to 360°.

[0083] Optionally, the spin cycle of washing is set to 2n+1, wherein n is greater than or equal to 1. In this way, washing can be made more efficient and the clothes can be loosened.

[0084] Illustratively, the spin cycle for washing is set to 3, 5 or 7.

[0085] Optionally, before detecting the eccentricity according to the load mass of each pulsator area, the method further includes: determining whether an abnormality occurs during the dehydration process of the washing machine. In this way, the method for controlling the dehydration of the washing machine can be more targeted.

[0086] Combine Figure 5 As shown, the embodiment of the present disclosure provides another method for controlling the dehydration of a washing machine, comprising:

[0087] S501: The washing machine determines that an abnormality occurs during the dehydration process.

[0088] S502: The washing machine detects eccentricity according to the load mass of each pulsator area.

[0089] S503 : When the washing machine is eccentric, the eccentric load area is determined based on the collected images of each pulsator area and the load mass.

[0090] S504: The washing machine controls the washing machine to perform corresponding operations according to the eccentric load area to complete dehydration.

[0091] By adopting the method for controlling the dehydration of a washing machine provided by the embodiment of the present disclosure, dehydration control can be performed when an abnormality occurs in the dehydration of the washing machine, which can more effectively reduce the dehydration abnormality caused by uneven distribution of clothes, improve the success rate of the dehydration of the washing machine, and enhance the user's product experience.

[0092] For example, an abnormality occurs in the washing machine during the dehydration process because the clothes in the drum are unevenly distributed, causing the outer drum to hit the safety switch, thereby terminating the dehydration process.

[0093] In practical applications, for example, the impeller is divided into four sector-shaped impeller regions D with equal areas. i , where i = 1, 2, 3, 4. During the dehydration process of the washing machine, the outer drum hits the safety switch due to uneven distribution of clothes in the drum. The mass sensors in the four impeller areas detect the load mass of each impeller area respectively. judge If it is true, it is determined that the washing machine is eccentric. If it is not true, it is determined that the washing machine is not eccentric and the washing machine is controlled to re-execute the dehydration process. If it is determined that the washing machine is eccentric, the clothes coverage area of ​​the four impeller areas is obtained through the image taken by the camera. Find the first condition The relative mass area and the second condition are satisfied , wherein i is not equal to g, and i is not equal to a. If there is no relative mass area and no relative area area, the control is to execute water rinsing, and then execute the dehydration process after the rinsing is completed. If there is no relative mass area and there is a relative area area, the relative area area is determined to be an eccentric load area. If there is a relative mass area and there is no relative area area, the relative mass area is determined to be an eccentric load area. If there is a relative mass area and there is a relative area area, it is further determined whether the relative mass area and the relative area area are the same area. If they are the same area, the relative mass area is determined to be an eccentric load area. If they are different areas, it is further determined whether the washing mode of the washing machine is a large load mode. When the sum of the load masses is greater than 30kg, that is, the washing mode is determined to be a large load mode, the relative mass area is determined to be an eccentric load area. When the sum of the load masses is less than or equal to 30kg, that is, the washing mode is determined not to be a large load, the relative area area is determined to be an eccentric load area. Based on the angle β between the determined eccentric load area and the preset starting area D1, the pulsator rotation angle ω2 = β + ω1 is calculated, where ω1 is 360°. The washing machine is controlled to start the wash cycle, with the motor driving the inner drum to rotate forward and reverse by an angle ω2. This determines a wash cycle. After five wash cycles, the machine drains the water and then performs a spin cycle. During the spin cycle, if the outer drum strikes the safety switch again, the above steps are repeated.

[0094] Combine Figure 6 As shown, an embodiment of the present disclosure provides a device 60 for controlling the dehydration of a washing machine, comprising a processor 600 and a memory 601. Optionally, the device may further include a communication interface 602 and a bus 603.
