Description

Technical Field

[0001] This application relates to the field of washing machines, and more specifically, to a spin-drying control method for a washing machine, electronic equipment, and a washing machine. Background Technology

[0002] When a washing machine spins, the clothes need to be laid out evenly to ensure uniform distribution before the spin speed is increased. This is to reduce the likelihood of the washing machine shifting or vibrating excessively during high-speed spin drying. In existing technology, experimental data is used to determine the optimal laying parameters for even clothing distribution, and a fixed eccentricity value and number of trials are set. After repeated trials during laying, the speed is increased only when the clothes are found to be evenly distributed, i.e., the eccentricity value is less than the preset value.

[0003] However, the existing method of determining the leveling parameters has the problem that even after the clothes have been leveled for a long time, they still cannot be evenly distributed, resulting in delayed dehydration or clothes that are not completely dry. Summary of the Invention

[0058] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0059] It should be understood that "multiple" as mentioned herein refers to two or more. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. In addition, to facilitate a clear description of the technical solutions of the embodiments of this application, the terms "first," "second," etc., are used in the embodiments of this application to distinguish identical or similar items with substantially the same function and effect. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and the terms "first," "second," etc., do not necessarily imply that they are different.

[0060] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0061] This embodiment proposes a spin-drying control method for washing machines. This spin-drying control method can be applied to both drum washing machines and pulsator washing machines. The term "clothes that can be processed by the washing machine" refers to any items that may be processed in the washing machine, including but not limited to: clothes, sheets, duvet covers, dolls, pillowcases, etc.

[0062] Reference Figure 1 The dehydration process flow chart shows that the dehydration control method in this embodiment includes the following steps:

[0063] S11. In the dehydration process, obtain the spatial parameters of the clothing representing the distribution of the clothing.

[0064] S12. Determine the garment load and / or target leveling parameters based on the garment space parameters and inner drum attribute parameters;

[0065] S13. Control the inner drum to level the clothes according to the load of the clothes and / or the target leveling parameters.

[0066] Specifically, in the dehydration process, the spatial parameters of the clothing representing the distribution state of the clothing are obtained. The spatial parameters of the clothing include the first distribution area of ​​the clothing on the inner drum sidewall and the second distribution area of ​​the clothing on the inner drum bottom wall, or may also include the thickness of the clothing relative to the inner drum sidewall.

[0067] In one example, an image of the clothes inside the drum can be acquired by a camera installed on the washing machine door, and the spatial parameters of the clothes can be determined by analyzing and processing the image. In another example, the spatial parameters of the clothes inside the drum can be determined by installing multiple infrared sensors on the washing machine door to emit infrared rays and receive infrared signals reflected back by the clothes inside the drum.

[0068] After determining the clothing space parameters, these parameters are combined with the inner drum attribute parameters to obtain the clothing load and / or target leveling parameters. The inner drum attribute parameters include the inner drum sidewall area and the inner drum bottom wall area. These parameters can be pre-stored in the washing machine's controller and retrieved during use. The clothing load reflects the distribution of clothing. In practical applications, clothing load can be categorized as high load, medium load, and low load. A higher load indicates a larger area of ​​clothing covering the drum wall, and vice versa. The target leveling parameters include leveling speed and leveling acceleration.

[0069] After determining the load of the clothes and / or the target leveling parameters, the inner drum can be controlled to level the clothes according to the load of the clothes and / or the target leveling parameters, so as to improve the efficiency of uniform distribution of clothes in the drum, shorten the leveling time, and improve the dehydration efficiency and dehydration effect.

[0070] In one alternative implementation, refer to Figure 2 The dehydration process flow chart determines the garment load and / or target leveling parameters based on garment space parameters and inner drum property parameters, including the following steps:

[0071] S21. Determine the first ratio between the first distribution area and the inner cylinder sidewall area;

[0072] S22. Determine the second ratio between the second distribution area and the inner cylinder bottom wall area;

[0073] S23. Determine the clothing load and / or target leveling parameters based at least on the first ratio and the second ratio.

[0074] Specifically, after determining the first distribution area and the second distribution area of ​​the clothes inside the drum, the first ratio of the first distribution area to the area of ​​the inner drum side wall and the second ratio of the second distribution area to the area of ​​the inner drum bottom wall are calculated. The distribution of the clothes inside the drum is determined based on the first ratio and the second ratio, and then the load of the clothes and / or the target leveling parameters are determined based on the distribution of the clothes inside the drum.

[0075] In one example: the garment load is determined at least based on a first ratio and a second ratio, including: the larger the sum of the first ratio and the second ratio, the greater the garment load; and different garment loads correspond to different leveling parameters. A greater garment load corresponds to a higher leveling rotation speed and a lower leveling acceleration.

[0076] This is because the larger the load of clothing and the larger the surface area of ​​the clothing, the more suitable it is to use a smaller acceleration to gradually increase the speed. During the acceleration process, the clothing will be slowly lifted by the lifting ribs, and the clothing will gradually unfold to cover the bottom of the drum. As the load decreases and the surface area of ​​the clothing decreases, the lifting ribs cannot quickly swing the clothing up and unfold it. It is necessary to use a larger acceleration to gradually increase the speed so that the clothing is not tightly attached to the drum at this speed. This allows for continuous unfolding during rotation, improving the uniform distribution of the clothing.

[0077] After determining the leveling parameters, the system enters the leveling stage, during which the inner drum is controlled to accelerate to the leveling speed corresponding to the load of the clothing, based on the leveling acceleration corresponding to the load of the clothing.

[0078] In one example, the target balancing parameters are determined at least based on a first ratio and a second ratio, including: the larger the sum of the first ratio and the second ratio, the greater the target balancing rotation speed; and / or, the larger the sum of the first ratio and the second ratio, the smaller the target balancing acceleration.

[0079] After determining the leveling parameters, the system enters the leveling stage and controls the inner drum to level the clothes according to the leveling speed and acceleration corresponding to the load of the clothes, or controls the inner drum to level the clothes according to the target leveling speed and acceleration.

[0080] In one alternative implementation, the clothing space parameters further include the thickness of the clothing relative to the inner drum sidewall; determining the clothing load and / or target leveling parameters based at least on a first ratio and a second ratio includes: determining the clothing load and / or target leveling parameters based on the first ratio, the second ratio, and the thickness.

[0081] Specifically, the thickness of the clothing reflects the degree of clothing accumulation inside the drum. When the area covered by the clothing inside the drum is small, the clothing thickness is further considered to determine the clothing load and / or target leveling parameters.

[0082] Combination Figure 4 Flowchart for determining clothing load and Figure 5The dehydration control flowchart determines the garment load based on a first ratio, a second ratio, and thickness. Specifically, if the sum of the first and second ratios is greater than or equal to a first preset value, the garment area is large, covering a large proportion of the drum's side and bottom, thus determining a large garment load. For example, the drum sidewall area is S. 侧 The bottom wall area of ​​the drum is S 底 The first distribution area A of the clothing on the inner side wall of the drum 侧 The second distribution area on the bottom wall of the inner cylinder is A. 底 The thickness of the garment relative to the inner wall of the inner tube is D. 衣 The sum of the first ratio and the second ratio is A. 侧 / S 侧 +A 底 / S 底 , when A 侧 / S 侧 +A 底 / S 底 When the value is ≥1, the clothing load is determined to be a large load.

[0083] When the sum of the first ratio and the second ratio is greater than or equal to the second preset value and less than the first preset value, the area of ​​the clothing is relatively large, and the proportion covering the sides and bottom of the drum is relatively large, thus the clothing load is determined to be a medium load. For example, when 0.5 ≤ A 侧 / S 侧 +A 底 / S 底 When the value is less than 1, the clothing load is determined to be a medium load.

[0084] When the sum of the first ratio and the second ratio is less than the second preset value, and the thickness is less than the preset thickness, the area of ​​the clothing is small, the proportion of the clothing covering the side and bottom of the drum is small, and the clothing is thin on the side wall, so there is no phenomenon of clothing piling up together. Therefore, the clothing load is determined to be a small load. For example, A... 侧 / S 侧 +A 底 / S 底 <0.5 and D 衣 When the thickness is less than 5cm, the load capacity of the clothing is determined to be small.

[0085] Among them, the balancing speed corresponding to the large load is the first balancing speed, and the balancing acceleration is the first acceleration; the balancing speed corresponding to the medium load is the second balancing speed, and the balancing acceleration is the second acceleration; the balancing speed corresponding to the small load is the third balancing speed, and the balancing acceleration is the third acceleration; satisfying: the preset eccentricity detection speed ≥ first balancing speed > second balancing speed > third balancing speed, and the first balancing acceleration < second balancing acceleration < third balancing acceleration.

[0086] For heavy loads, the large surface area of ​​the garments makes it suitable to use a smaller initial leveling acceleration to gradually increase the initial leveling speed. During this increase, the garments are slowly lifted by the lifting ribs, gradually unfolding and covering the bottom of the drum. For example, the initial leveling speed is 90 rpm, and the initial leveling acceleration is 10 rpm. When the load is medium, the garment surface area is still large. Using too small an acceleration will prevent the garments from being quickly lifted and unfolded by the lifting ribs. A moderate second leveling acceleration is needed to reach a moderate second speed. At this speed, the garments can adhere to the back drum, but not tightly, allowing for continuous unfolding and maintenance for a certain period during rotation. For example, the second leveling speed is 70 rpm, and the second leveling acceleration is 20 rpm. When the load is light, the garments cannot unfold in the back drum; they only need to unfold on the side walls. A larger third leveling acceleration is used to quickly increase the speed to a lower third leveling speed. At this low speed, the garments on the side walls can unfold and maintain their position for a certain period. The third swing rotation speed is, for example, 50 r / s, and the third swing acceleration is, for example, 30 r / s.

[0087] In other feasible methods, the target leveling parameters are directly determined based on the first ratio, the second ratio, and the thickness. Specifically, if the sum of the first ratio and the second ratio is greater than or equal to a first preset value, the target leveling parameters are determined to be the first leveling acceleration and the first leveling rotation speed. If the sum of the first ratio and the second ratio is greater than or equal to the second preset value and less than the first preset value, the target leveling parameters are determined to be the second leveling acceleration and the second leveling rotation speed. If the sum of the first ratio and the second ratio is less than the second preset value and the thickness is less than a preset thickness, the target leveling parameters are determined to be the third leveling acceleration and the third leveling rotation speed.

[0088] Wherein: the preset eccentricity detection speed is ≥ first leveling speed > second leveling speed > third leveling speed, and the first leveling acceleration is < second leveling acceleration < third leveling acceleration.

[0089] Since the sum of the first and second ratios, combined with the garment thickness, reflects the garment load, and different garment loads are suited to different leveling speeds and accelerations, in practical applications, the garment load can be determined first based on the sum of the first and second ratios and the garment thickness, and then the corresponding leveling speed and acceleration can be determined based on the garment load. A more preferred approach is to not determine the garment load, but instead directly determine the leveling speed and acceleration based on the sum of the first and second ratios and the garment thickness, thus reducing logical steps and improving the efficiency of leveling parameter determination.

[0090] In one alternative implementation, refer to Figure 3The dehydration process flowchart, which obtains spatial parameters representing the distribution of clothing, includes the following steps:

[0091] S31. First, control the inner cylinder to accelerate to the preset eccentricity detection speed with the first preset acceleration, and perform eccentricity detection at the preset eccentricity detection speed;

[0092] S32. If the detected eccentricity value meets the preset acceleration conditions, obtain the clothing space parameters.

[0093] Specifically, in combination Figure 5 The flowchart illustrates that after the washing machine enters the spin-drying cycle, the inner drum needs to be accelerated to the detection speed at a first preset acceleration, for example, 15 r / s, and the detection speed is for example, 90 r / s. While the inner drum is rotating at the detection speed, eccentricity detection is performed to determine the degree of imbalance caused by uneven distribution of clothes during the washing machine's operation. For example, by reading parameters such as motor current, speed, and power in real time and processing these parameters, an eccentricity value can be obtained.

[0094] When the eccentricity value is less than or equal to the preset eccentricity value, it indicates that the clothes inside the drum are evenly distributed, thus meeting the preset speed-up conditions. In this case, the height can be increased directly for dehydration. When the eccentricity value is greater than the preset eccentricity value, it indicates that the clothes inside the drum are unevenly distributed, requiring leveling. In this case, the clothes space parameters are obtained while detecting the eccentricity speed. These parameters are then combined with the drum properties to determine the clothes load and / or target leveling parameters. The clothes are then leveled based on the clothes load and / or target leveling parameters.

[0095] In one optional implementation, refer to Figure 5 The dehydration process flow chart shows that when the inner drum speeds up to the leveling speed corresponding to the load of the clothes, or after speeding up to the target leveling speed, if the speed of the inner drum at this time reaches the preset eccentricity detection speed, then eccentricity detection is performed directly at the eccentricity detection speed; if the speed of the inner drum at this time is lower than the preset eccentricity detection speed, then after maintaining this speed for a preset time, the inner drum is controlled to speed up to the preset eccentricity detection speed with a second preset acceleration, and then eccentricity detection is performed at the preset eccentricity detection speed. The second preset acceleration is, for example, 15 r / s.

[0096] If the detected eccentricity value meets the preset acceleration conditions, the inner drum is controlled to accelerate for dehydration; if the detected eccentricity value does not meet the preset acceleration conditions, the step of obtaining clothing space parameters is repeated.

[0097] In the above embodiments of this application, the descriptions of each embodiment have their own emphasis. Parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments. The steps illustrated in the related flowcharts can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be executed in a different order than that shown here. In other words, the order of steps described in the foregoing embodiments is merely an example. Reasonable adjustments to the order of steps based on the content of the embodiments of this application are also permitted in this application.

[0098] This application also provides an electronic device, which includes one or more processors and a non-transitory computer-readable storage medium storing program instructions. When the one or more processors execute the program instructions, the one or more processors are used to implement the dehydration control method proposed above.

[0099] Specifically, such as Figure 6 As shown, the electronic device includes a processor 100, at least one communication bus 200, a user interface 300, at least one external communication interface 400, and a memory 500. The communication bus 200 is configured to enable communication between these components. The user interface 300 may include a display screen, and the external communication interface 400 may include standard wired and wireless interfaces. The memory 500 stores a spin-drying control method for a washing machine. The processor 100 is used to employ the aforementioned method when executing the spin-drying control method for the washing machine stored in the memory 500.

[0100] This embodiment also proposes a washing machine for performing the spin-drying control method proposed above, or including the electronic equipment proposed above.

[0101] In one alternative implementation, refer to Figure 7 The washing machine structure diagram shows that the washing machine includes a front panel 1, a door, and multiple infrared sensors 12. The door is located on the front panel 1, and the multiple infrared sensors 12 are located on the door for detecting clothing space parameters and inner drum attribute parameters. Preferably, the door includes a glass bowl 11, and the multiple infrared sensors 12 are spaced apart along the circumferential direction of the glass bowl 11.

[0102] Infrared sensor 12 emits infrared light and receives reflected infrared signals. The absorption and reflectivity of infrared light differ significantly between the smooth surface of the washing machine drum and the fabric of the clothes. As the washing machine drum rotates, the distribution of clothes changes dynamically. Infrared sensor 12 needs to scan continuously at a frequency of 50-100Hz. In one example, such as... Figure 3As shown, 8-12 sets of infrared transmitter-receiver pairs are evenly arranged around the 11th circumference of the glass bowl, covering a 360° area. The spacing between each set is approximately 15-20cm, ensuring comprehensive detection of the interior of the inner cylinder.

[0103] Infrared reflection signals differ between the inner drum surface of the washing machine and the clothes, thus distances can be determined based on the reflected signals. The controller stores the empty drum distances of various points within the washing machine drum as measured by the infrared sensor 12. When clothes are present inside the drum, the infrared sensor 12 can determine the distribution of the clothes within the drum. The difference between the distance determined by the infrared signal reflected from the location of the clothes and the distance when the drum is empty is the thickness of the clothes. A first distribution area is determined based on the range where the distance of the infrared signal reflected from the inner drum sidewall is less than the range where the inner drum sidewall is empty, and a second distribution area is determined based on the range where the distance of the infrared signal reflected from the inner drum bottom wall is less than the range where the inner drum bottom wall is empty.

[0104] The washing machine in this embodiment can effectively improve the efficiency of even distribution of clothes, reduce the time for clothes to be laid flat, shorten the duration of the entire spin-drying process, and improve the spin-drying effect.
