[0076] With the increasing adoption of ultra-thin designs in front-loading washing machines, the inner drum diameter is constantly increasing, while the gap between the inner and outer drums is decreasing. This leads to the phenomenon of spinning with water remaining during the spin-drying process, resulting in clothes having more water on them after washing. Spinning with water also affects the rinsing effect, leaving more residue on the clothes. Sometimes, the washing machine is noisy during the spin-drying process, increasing the spin-drying power and wasting electricity. Furthermore, the noise and drainage capacity of the drain pump cannot be adjusted, leading to a poor user experience.

[0077] This application provides a control method, control device, washing equipment, and storage medium for a washing machine, to solve the problems of existing washing machines easily causing water-borne spin-drying and excessive noise. The following description will be provided in conjunction with Figures 1-6.

[0078] The control method for washing equipment provided in this application embodiment can be applied to washing machines, washer-dryer combos, or washer-dryer sets, etc. For example, please refer to Figure 1, which is a flowchart illustrating the control method for washing equipment provided in this application embodiment. The control method for washing equipment includes:

[0079] S101: Control the washing drum of the washing equipment to gradually increase the spin-drying speed for spin-drying;

[0080] When the spin-drying program begins, the washing machine gradually increases the drum speed to more effectively remove water from the clothes. S102: Obtain drum speed information;

[0081] For example, the washing equipment monitors the current rotation speed of the washing drum through a sensor and transmits the current rotation speed to the control unit for processing, which serves as the basis for determining the subsequent dehydration stage and adjusting the operating frequency of the drain pump.

[0082] S103: Determine the dehydration stage of the garment based on rotation speed information;

[0083] After receiving the rotation speed information, the control unit of the system device analyzes the rotation speed information to determine the dehydration stage of the clothes. For example, this can be achieved by comparing the current rotation speed information with the preset rotation speed thresholds for the rapid dehydration stage and the slow dehydration stage.

[0084] In one optional implementation, determining the dehydration stage of the clothing based on the rotation speed information includes: determining the dehydration stage as a rapid water loss stage when the rotation speed information increases from a first rotation speed to a preset rotation speed; and determining the dehydration stage as a slow water loss stage when the rotation speed information is maintained at the highest rotation speed, or when the speed decreases after dehydration is completed.

[0085] Understandably, in this embodiment, when the washing equipment is in the process of spin-drying from the first rotation speed to the preset rotation speed, the control unit determines this stage as the rapid water loss stage. In this initial stage of spin-drying, a large amount of water in the clothes is thrown out due to the high-speed rotation, so the drain pump needs to work at a higher frequency to ensure that the water can be discharged quickly and avoid the phenomenon of spin-drying with water in due to untimely drainage.

[0086] Once the washing drum reaches and maintains its maximum speed, or as the spin-drying process nears completion and the speed begins to decrease from its peak, the control unit defines this stage as the slow water loss stage. During this stage, most of the water in the clothes has been removed, and the remaining water drains at a slower rate. Therefore, the operating frequency of the drain pump can be reduced accordingly, minimizing unnecessary energy consumption and noise during inefficient operation, thus improving user comfort. For example, the first speed range can be 80-100 rpm, and the preset speed range can be 400-600 rpm. The maximum speed is the highest speed set by the washing machine in the spin-drying program, and its specific value can be set according to actual conditions. Optionally, the first speed and preset speed values ​​can also be other values, set according to the fabric material and washing machine performance, etc. This embodiment does not specifically limit these values.

[0087] S104: When the dehydration stage is a rapid water loss stage, increase the operating frequency of the drain pump; when the dehydration stage is a slow water loss stage, decrease the operating frequency of the drain pump.

[0088] When the system determines that the clothes are in the rapid water loss stage, that is, when the water in the clothes is being quickly shaken out, the control unit can control the drain pump to increase its working frequency to ensure that the water can be discharged quickly and avoid the phenomenon of dehydration with water, which would affect the washing and dehydration effects.

[0089] Conversely, when clothes enter the slow water loss stage, with less moisture in the clothes and a slower dehydration speed, the control unit can reduce the operating frequency of the drain pump. This not only saves energy but also reduces the noise of the drain pump when it is working inefficiently. It satisfies the drainage problem of the dehydration process while also taking into account the noise problem, improving the user experience and making the entire dehydration and drainage process more stable and efficient.

[0090] In an optional implementation, after determining the dehydration stage of the clothes based on the rotation speed information, the method further includes: acquiring the water level frequency value of the washing drum, and increasing the operating frequency of the drain pump if the water level frequency value is greater than a preset water level frequency value. For example, the washing equipment detects the water level frequency value of the washing drum, i.e., the water level height inside the washing drum, through a built-in water level sensor. When the water level frequency value is greater than the preset water level frequency value, it indicates that the water level inside the washing drum is high, water is being rapidly expelled, and stronger drainage capacity is needed to avoid dehydration with water remaining. At this time, the control unit can automatically increase the operating frequency of the drain pump to accelerate the drainage speed, ensuring that water can be discharged in a timely manner, thereby effectively preventing the water level from rising and avoiding the clothes from being soaked in water during high-speed dehydration, thus improving dehydration efficiency and the dryness of the clothes.

[0091] In some alternative implementations, the water level frequency value can be divided into multiple stages, with different ranges of water level frequency values ​​matched with different operating frequencies of the drainage pump. This allows for more accurate adjustment of the drainage pump's operating frequency based on the water level height, achieving energy saving and noise reduction.

[0092] In an optional implementation, after determining the dehydration stage of the garment based on the rotation speed information, the method further includes: determining the weight information and absorbency of the garment; adjusting the operating frequency of the drain pump according to a first mode when the weight information is less than or equal to a preset weight and the absorbency is less than or equal to a preset threshold; and adjusting the operating frequency of the drain pump according to a second mode when the weight information is greater than the preset weight and the absorbency is greater than the preset threshold; wherein the operating frequency of the drain pump in the first mode is less than the operating frequency of the drain pump in the second mode.

[0093] Specifically, the washing equipment can measure the weight of the clothes using a built-in weight sensor, and the water absorption performance can be determined by detecting the water intake and the water level in the washing drum.

[0094] When the weight of the clothing is less than or equal to a preset weight, and the water absorption capacity is less than or equal to a preset threshold, the system adjusts the operating frequency of the drain pump according to the first mode. In this case, the clothing is lighter and does not easily absorb water, so the operating frequency of the drain pump can be relatively low to save energy and reduce noise.

[0095] When the weight of the clothing exceeds a preset weight and the absorbency exceeds a preset threshold, the system adjusts the operating frequency of the drain pump according to the second mode. In this case, the clothing is heavier and absorbs water more easily, requiring a higher drain pump operating frequency to ensure effective dehydration.

[0096] By adjusting the spin-drying strategy based on the weight and absorbency of the garments, a more suitable spin-drying effect is provided for different garment needs. When high drainage efficiency is not required, the operating frequency of the drain pump is reduced to decrease energy consumption; when the garments are lighter, the operating frequency of the drain pump is also reduced to decrease noise during the washing process. When the garments are heavier and have better absorbency, the operating frequency of the drain pump is increased to ensure that the water spun out during the spin-drying stage is effectively discharged, avoiding the phenomenon of spin-drying with water remaining.

[0097] In an optional implementation, referring to Figure 3, the first mode specifically includes: controlling the drain pump to operate at a first operating frequency as the rotational speed gradually increases from a first rotational speed to a second rotational speed; the first operating frequency is determined based on a first initial frequency and water absorption performance, and the first operating frequency is greater than the first initial frequency; controlling the drain pump to operate at the first initial frequency as the rotational speed is maintained at the second rotational speed; and controlling the drain pump to operate at a second operating frequency as the rotational speed continues to increase from the second rotational speed; the second operating frequency is determined based on the first initial frequency and water absorption performance, and the second operating frequency is greater than the first operating frequency.

[0098] For example, during the spin-drying process of the washing drum gradually increasing from a first speed (e.g., 93 rpm) to a second speed (e.g., 400 rpm), which is the initial stage of spin-drying, water is easily extracted from the clothes, and a relatively large amount of water is extracted. The first operating frequency of the drain pump is f = F0 + a0 * (X / X0) * F0, where F0 represents the first initial frequency, X is the water absorption performance, X0 represents the preset threshold, and a0 is a coefficient. When the spin-drying speed of the washing drum is maintained at the second speed (e.g., 400 rpm), the amount of water extracted from the clothes is relatively stable, and the operating frequency of the drain pump can be appropriately reduced, that is, the drain pump is controlled to operate at the first initial frequency F0. Then, continue to control the washing drum to increase the spin speed. As the spin speed of the washing drum continues to increase from the second speed (e.g., 400 rpm) to the highest speed, the remaining water in the clothes can be removed more quickly. Therefore, the operating frequency of the drain pump needs to be increased for drainage. The second operating frequency of the drain pump can be f = F0 + a1*(X / X0)*F0, where a1 > a0, making the second operating frequency greater than the first operating frequency. For example, F0 = 50 Hz, a0 = 0.02.

[0099] In the initial stage of dehydration, the operating frequency of the drain pump is increased to ensure that a large amount of water is quickly discharged, avoiding dehydration with water remaining and improving dehydration efficiency. In the stable stage of dehydration, the operating frequency of the drain pump is reduced to minimize unnecessary energy consumption and noise. In the later stage of dehydration, the operating frequency of the drain pump is further increased to ensure that the moisture in the clothes is fully removed, improving dryness.

[0100] In an optional implementation, the second mode specifically includes: controlling the drain pump to operate at a third operating frequency as the rotational speed gradually increases from a first rotational speed to an intermediate rotational speed; the third operating frequency is determined based on a second initial frequency and water absorption performance, and the third operating frequency is greater than the second initial frequency; controlling the rotational speed of the washing drum to decrease to a predetermined rotational speed, and controlling the drain pump to operate at the second initial frequency; controlling the drain pump to operate at a fourth operating frequency as the rotational speed gradually increases from an intermediate rotational speed to a second rotational speed; the fourth operating frequency is determined based on the second initial frequency and water absorption performance, and the fourth operating frequency is greater than the third operating frequency; controlling the drain pump to operate at the second initial frequency as the rotational speed remains at the second rotational speed; and controlling the drain pump to operate at a fifth operating frequency as the rotational speed continues to increase from the second rotational speed; the fifth operating frequency is determined based on the second initial frequency and water absorption performance, and the fifth operating frequency is greater than the fourth operating frequency.

[0101] For example, referring to Figure 4, in the second mode, as the spin speed of the washing drum gradually increases from the first speed (e.g., 90 rpm) to the intermediate speed (e.g., 200 rpm), it is in the initial stage of spin-drying. Due to the weight of the clothes and their strong water absorption, a lot of water is removed even at the lower speed of the washing drum (compared to the second speed in the first mode). The third operating frequency of the drain pump is f = F1 + a1*(X / X0)*F0, where F1 represents the second initial frequency, X is the water absorption capacity, X0 represents the preset threshold, a1 is a coefficient, and F1 > F0. Then, the speed of the washing drum is controlled to decrease to a lower predetermined speed (e.g., 120 rpm or below) and maintained for a period of time. During this process, the drain pump is controlled to operate at the second initial frequency. During this maintenance, the amount of water removed from the clothes is relatively stable, and the operating frequency of the drain pump can be appropriately reduced. During the process of the washing drum's spin-drying speed increasing from the predetermined speed to the second speed, the fourth operating frequency of the drain pump is f = F1 + a2 * (X / X0) * F0, and a2 > a1, thus making the fourth operating frequency greater than the third operating frequency.

[0102] When the washing drum's spin speed is maintained at the second speed (e.g., 400 rpm), the amount of water removed from the clothes is relatively stable. The operating frequency of the drain pump can be appropriately reduced, i.e., the drain pump can be controlled to operate at the second initial frequency F1. Then, the washing drum's spin speed is further increased. As the spin speed continues to rise from the second speed (e.g., 400 rpm) to the maximum speed, the remaining water in the clothes can be removed more quickly. Therefore, the operating frequency of the drain pump needs to be increased for drainage. The fifth operating frequency of the drain pump can be f = F1 + a3*(X / X0)*F0, where a3 > a2, thus making the fifth operating frequency greater than the fourth operating frequency.

[0103] Optionally, F1 = 54Hz, a2 = 0.06, and a3 = 0.08. Optionally, the above parameters can also be other values, set according to actual needs, and this embodiment does not specifically limit them.

[0104] Compared to the first mode, the second mode divides the dehydration process into more stages, each with a different operating frequency, to better adapt to the changing moisture loss during dehydration when the garments are heavy and have strong absorbency. During the rapid water loss stage (90-400 rpm), multi-stage dehydration and increased drainage frequency are used to improve drainage performance and avoid dehydration with the garment still wet.

[0105] In one optional implementation, the method for determining water absorption performance includes: recording the water intake volume during the water intake process of the washing drum; controlling the rotation of the washing drum; replenishing water to the washing drum and recording the replenished water volume and the current water volume after replenishment; and calculating the water absorption performance based on the water intake volume, the replenished water volume, and the current water level of the washing drum.

[0106] For example, referring to Figure 2, after the washing program starts, the clothes in the washing drum can be weighed to obtain the weight value w. The washing drum remains stationary, and the drain valve is opened to allow water to enter the washing drum to the set water level. During the water entry process, the water volume V1 is measured by a flow meter. Then, the washing drum is controlled to rotate, and the clothes rotate in the water to absorb water, replenishing the washing drum for a predetermined time. At the same time, the replenished water volume V2 is recorded, and the current water level in the washing drum is detected. Based on the current water level, the remaining water volume a in the washing drum can be calculated. Then, the water absorption performance X = (V1 + V2 - a) / W.

[0107] Based on the absorbency and weight of the clothing, the equipment can intelligently adjust the operating frequency of the drain pump to achieve efficient dehydration while reducing energy consumption and noise.

[0108] In one optional implementation, both the first mode and the second mode include: acquiring the water level frequency value of the washing drum; when the rotation speed information increases to a preset rotation speed and the water level frequency value is greater than the preset frequency value, controlling the operating frequency of the drain pump to increase to a first frequency value; when the rotation speed information increases from the preset rotation speed to the highest frequency, controlling the operating frequency of the drain pump to increase to a second frequency value; wherein the second frequency value is greater than the first frequency value.

[0109] For example, in the first mode and the second mode, during the process of the washing drum speed information increasing to the preset speed (e.g., the second speed 400 rpm), if the water level frequency value is detected to be greater than the preset frequency value, the operating frequency of the drain pump is controlled to be f+f1. If the washing drum speed information is in the process of continuing to increase from the preset speed, and the water level frequency value is detected to be greater than the preset frequency value, the operating frequency of the drain pump is controlled to be F0+f2 in the first mode and F1+f2 in the second mode, where f is the original operating frequency corresponding to the current speed, f1 is the first frequency value, f2 is the second frequency value, and f2>f1.

[0110] As the washing drum speed continues to increase in the second rotation speed, even if the amount of water in the drum is not large, the high rotation speed and strong suction force require a higher operating frequency of the drain pump to effectively discharge the water. Therefore, the second frequency value f2 is greater than the first frequency value f1. For example, f2 = 6 Hz and f1 = 4 Hz. f1 and f2 can also be other values, but this embodiment does not impose specific limitations.

[0111] In this embodiment, the operating frequency of the drain pump is adaptively adjusted according to the washing drum's rotation speed and water level to achieve efficient drainage. When necessary, the operating frequency of the drain pump is increased to ensure that clothes are fully drained during high-speed spin-drying, improving dryness. The control method for the washing equipment provided in this application embodiment includes: gradually increasing the spin-drying speed of the washing drum; acquiring the washing drum's rotation speed information; determining the dehydration stage of the clothes based on the rotation speed information; increasing the operating frequency of the drain pump when the dehydration stage is a rapid water loss stage; and decreasing the operating frequency of the drain pump when the dehydration stage is a slow water loss stage.
