Description

Technical Field

[0001] This application relates to the field of washing machine control technology, specifically to a drainage control method, device, washing machine, and computer-readable storage medium. Background Technology

[0002] Washing machines generally use a vane centrifugal pump as the drain pump to remove dirty water generated during the washing process.

[0003] However, current drain pumps only drain water according to a fixed drainage rhythm without considering other factors that affect the drainage effect, such as excessive foam in the drum or air binding in the drain pump. This results in incomplete drainage, leaving a large amount of water in the washing machine drum after drainage, which affects the subsequent spin-drying effect of the washing machine. Summary of the Invention

[0004] Embodiments of this application provide a drainage control method, apparatus, washing machine, and computer-readable storage medium, aimed at improving the drainage performance of the washing machine.

[0005] In a first aspect, embodiments of this application provide a drainage control method, comprising:

[0006] The actual water level in the inner tub and the actual motor power of the washing machine motor are obtained during the spin-drying stage of the washing machine.

[0007] The target drainage parameters of the washing machine are obtained based on the actual water level and the preset defoaming water level, as well as the actual motor power and the preset spin-drying power threshold.

[0008] According to the target drainage parameters, the load inside the washing machine drum is drained until the spin-drying is complete.

[0009] Secondly, embodiments of this application provide a drainage control device, comprising:

[0010] The first acquisition module is used to acquire the actual water level in the inner tub and the actual motor power of the washing machine motor during the spin-drying stage of the washing machine.

[0011] The second acquisition module is used to acquire the target drainage parameters of the washing machine based on the actual water level and the preset defoaming water level, as well as the actual motor power and the preset dehydration power threshold.

[0012] The drainage module is used to drain the load inside the washing machine drum according to the target drainage parameters until the spin-drying is completed.

[0013] Thirdly, embodiments of this application provide a washing machine, including a processor and a memory, the memory storing multiple instructions; the processor loads instructions from the memory to execute the steps of the above-described drainage control method.

[0015] The beneficial effects of the embodiments of this application are as follows:

[0016] In this embodiment, the washing machine can obtain the actual water level in the inner tub and the actual motor power of the washing machine motor in real time during the spin-drying stage. Based on the actual water level, a preset defoaming water level, the actual motor power, and a preset spin-drying power threshold, the washing machine can obtain target drainage parameters. According to these target drainage parameters, the load inside the washing machine tub is drained. Therefore, this embodiment considers the impact of foam generated during the washing process on drainage, as well as the impact of incomplete drainage on subsequent spin-drying. By controlling the washing machine to drain according to the preset defoaming water level and preset spin-drying power threshold, complete drainage can be achieved, improving the washing machine's drainage performance. This ensures normal subsequent spin-drying, avoids incomplete cleaning or spin-drying of the load inside the tub, and improves the user experience. Attached Figure Description

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing direction in the accompanying drawings; while "inner" and "outer" refer to the outline of the device. At the same time, in the description of the embodiments of this application, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0025] The following problems may occur during the operation of a washing machine:

[0026] (1) Air binding phenomenon in washing machine drain pump; In order to save on raw material costs, many washing machine manufacturers choose the relatively inexpensive vane centrifugal pump as the drain pump for their washing machines. This may cause air binding during the draining and spin-drying stages of the washing machine, resulting in the inability to drain properly. Air binding refers to the presence of air inside the centrifugal pump. Because the air density is very low compared to the liquid being transported, the centrifugal force generated after rotation is small. Therefore, the low pressure formed in the central area of ​​the centrifugal pump impeller is insufficient to draw liquid into the pump, resulting in the inability to transport liquid even when the centrifugal pump is started. That is, the high-speed rotation of gas inside the centrifugal pump at the center of the impeller during startup cannot create a sufficient vacuum, so the liquid at the pump inlet cannot be drawn into the pump chamber, causing the pump to run dry. This phenomenon is called air binding in centrifugal pumps. Therefore, if the drain pump is in an inappropriate start-stop cycle when air binding occurs in the washing machine drain pump, it will cause the drain pump to fail to drain water, leading to spin-drying and drying failures, severely reducing the washing performance of the washing machine and seriously affecting the user experience.

[0027] (2) Defoaming treatment of washing machine; if there is too much detergent or washing powder residue or too much calcium and magnesium ions in the water, even after drainage, there will still be a lot of foam on the clothes. When the motor rotates at high speed, the foam may increase or even splash out, which will not only make the clothes not clean, but also affect the dehydration performance of the washing machine.

[0028] (3) The washing machine spins with water in it; when the drain pump cannot drain the water in a short time due to air binding or other reasons (even in the intelligent drain mode of the washing machine, it takes time to verify the drainage effect and cannot drain the water in the drum immediately), the spin speed often does not wait for the drainage to be completed, which leads to the washing machine spins with water in it. That is, even if the water of the clothes is spun out from the inner drum, it stays in the gap between the inner and outer drums because the drainage effect is not ideal. At this time, the inner drum rotates at high speed and spun the water back to the top and near the top of the outer drum. The water will fall back into the clothes in the inner drum due to gravity, and this cycle repeats. The water can never reach the inlet of the drain pump and is frequently spun up by the motor drum. This spins with water in it will seriously affect the spin performance and life of the washing machine, resulting in very high motor power and very loud noise.

[0029] Therefore, in general, as described in the background section of this application, the current drain pump only drains water according to a fixed drainage rhythm without considering other factors that affect the drainage effect, such as excessive foam in the drum or air binding in the drain pump, which leads to incomplete drainage. After drainage, a large amount of water remains in the washing machine drum, affecting the subsequent spin-drying effect of the washing machine.

[0030] To address the aforementioned issues and improve the drainage and spin-drying performance of a washing machine, this embodiment proposes a drainage control method, apparatus, washing machine, and computer-readable storage medium, aiming to enhance the drainage performance and subsequent spin-drying performance of the washing machine.

[0031] Specifically, the drainage control method in this application, such as Figure 1 As shown, the specific steps include:

[0032] Step S10: Obtain the actual water level in the inner tub and the actual motor power of the washing machine motor during the drainage stage of the washing machine.

[0033] It should be noted that, as explained above, residual foam on clothes can affect the drainage and spin-drying performance of the subsequent load in the drum (i.e., the clothes to be washed), and may also prevent the clothes from being completely clean. Additionally, incomplete drainage during spin-drying, resulting in water remaining, will also affect the subsequent spin-drying effect.

[0034] Therefore, in this embodiment, the washing machine can detect the actual water level of the inner tub and the actual motor power of the washing machine motor in real time during the drainage stage of the washing machine. Specifically, the motor can be a drive motor that drives the inner tub of the washing machine to rotate.

[0035] S20, based on the actual water level and the preset defoaming water level, as well as the actual motor power and the preset dehydration power threshold, obtain the target drainage parameters of the washing machine;

[0036] It is understood that the preset defoaming water level in this embodiment refers to the water level used by the washing machine during the spin-drying process. During spin-drying, the washing machine spins the water out of the clothes at high speed, creating a high-speed rotating environment. However, due to detergents and other factors, a large amount of foam may sometimes be generated during this process. Therefore, to avoid excessive foam interfering with the spin-drying effect, the washing machine usually uses a lower water level for drainage before spin-drying, which is the defoaming water level. This aims to remove detergent and foam, ensuring that the water in the clothes is removed more effectively during the spin-drying process. The preset defoaming water level in this embodiment helps to improve the spin-drying effect, allowing the washed clothes to dry faster. Furthermore, since the motor power for spin-drying with water is much higher than the maximum motor power under normal clothes spin-drying conditions, this embodiment can also pre-determine a preset spin-drying power threshold.

[0037] Based on this, after obtaining the actual water level in the inner tub and the actual motor power during the washing machine's drainage stage, the washing machine can obtain the target drainage parameters of the washing machine according to the actual water level and the preset defoaming water level, as well as the actual motor power and the preset spin-drying power threshold.

[0038] The aforementioned target drainage parameters may include parameters such as drainage cycle time and drainage time. It can be understood that the drainage cycle time in this embodiment can specifically be the start-stop cycle of the drainage pump. For example, the drainage pump runs for 20 seconds and stops for 4 seconds as a start-stop cycle.

[0039] S30, drain the load inside the washing machine drum according to the target drainage parameters until the spin-drying is completed.

[0040] After obtaining the target drainage parameters of the washing machine based on the actual water level, the preset defoaming water level, the actual motor power, and the preset spin-drying power threshold, the washing machine can drain the load inside the drum according to the target drainage parameters until the spin-drying is completed.

[0041] For example, the washing machine can control the drain pump to drain water and control the washing machine to perform defoaming treatment based on the drainage rhythm in the target drainage parameters.

[0042] Therefore, in this embodiment, the washing machine can obtain the actual water level in the inner tub and the actual motor power of the washing machine motor in real time during the spin-drying stage. Based on the actual water level, a preset defoaming water level, the actual motor power, and a preset spin-drying power threshold, the washing machine can obtain target drainage parameters. According to these target drainage parameters, the load inside the washing machine tub is drained. Thus, this embodiment considers the impact of foam generated during the washing process on drainage, as well as the impact of incomplete drainage on subsequent spin-drying. By controlling the washing machine to drain according to the preset defoaming water level and preset spin-drying power threshold, complete drainage can be achieved, improving the washing machine's drainage performance and ensuring normal subsequent spin-drying. This avoids incomplete cleaning or spin-drying of the load inside the tub, improving the user experience.

[0043] In one embodiment, in S20 above, "obtaining the target drainage parameters of the washing machine based on the actual water level and the preset defoaming water level, as well as the actual motor power and the preset spin-drying power threshold" may include:

[0044] S201, if the actual water level exceeds the preset defoaming water level and the actual motor power does not exceed the preset dehydration power threshold, then obtain the change information of the actual water level;

[0045] S202, based on the target average water level for a first preset time and the preset water level range in the actual water level change information, obtain the first target drainage parameters of the washing machine.

[0046] It should be noted that, in this embodiment, according to the above description, in order to avoid excessive foam interfering with the dehydration effect, the washing machine usually uses a low water level to drain the water before dehydration, which is the defoaming water level, in order to remove the detergent and foam, so as to ensure that the water in the clothes is spun off more effectively during the dehydration process.

[0047] Based on this, such as Figure 2 As shown, the washing machine can continuously monitor the water level in the inner tub during the spin-drying stage. If the actual water level exceeds the preset defoaming water level and the actual motor power does not exceed the preset spin-drying power threshold, the machine can obtain information on the change in the actual water level.

[0048] Specifically, for example, such as Figure 2 As shown, the washing machine can calculate the actual water level of the inner tub every 0.5 seconds when the actual water level exceeds the preset defoaming water level, and accumulate the data for 10 seconds to obtain 20 changes in the actual water level of the inner tub.

[0049] Furthermore, the washing machine can obtain the target average water level for the first preset time period from the above-mentioned actual water level change information, and obtain the first target drainage parameters of the washing machine based on the target average water level and the preset water level range.

[0050] Specifically, in S202 above, "obtaining the first target drainage parameter of the washing machine based on the target average water level for a first preset time period and the preset water level range in the actual water level change information" may include:

[0051] S2021, Obtain the target water level interval corresponding to the target average water level for the first preset time in the actual water level change information;

[0052] S2022, obtain the first target drainage parameters corresponding to the target water level range, wherein the first target drainage parameters include: load spraying duration, defoaming settling duration, first drainage cycle time, and first drainage time.

[0053] In this embodiment, as Figure 2 As shown, after the washing machine obtains the actual water level change information of the inner tub, it can calculate the target average water level for a preset time period in the change information, such as the target average water level of 20 actual water levels within 10 seconds.

[0054] Furthermore, the washing machine can determine the target water level range corresponding to the target average water level, and obtain the first target drainage parameters corresponding to the target water level range, such as... Figure 2 As shown, the first target drainage parameters in this embodiment may include at least: load spraying duration, defoaming settling duration, first drainage cycle time, and first drainage time.

[0055] It is understood that, in this embodiment, the washing machine can adopt a corresponding drainage strategy according to the different actual water levels in the drum. The drainage parameters of the washing machine can be flexibly adjusted by using a fuzzy control method for water level range, so that the washing machine can drain completely.

[0056] Based on this, in S30 above, "draining the load inside the washing machine drum according to the target drainage parameters until spin-drying is complete" may include:

[0057] S301, spray the load in the tank according to the load spraying time, and let the load in the tank stand after spraying according to the defoaming and settling time.

[0058] S302, drain the load in the barrel after static treatment according to the first drainage cycle and the first drainage time until dehydration is completed.

[0059] In this embodiment, after determining the load spraying duration, defoaming settling time, first drainage cycle, and first drainage time, the washing machine can perform a defoaming operation based on the above parameters.

[0060] Specifically, for example, the washing machine can spray the load inside the drum according to the above-mentioned load spraying time, and let the sprayed load inside the drum stand for a period of time to remove excess foam from the surface of the load inside the drum. Then, it can drain the load inside the drum after the standing treatment according to the above-mentioned first drainage rhythm and first drainage time.

[0061] It is understood that, according to the above description, the drainage cycle in this embodiment can specifically be the start-stop cycle of the drainage pump. For example, a start-stop cycle is defined as the drainage pump running for 20 seconds and stopping for 4 seconds. The duration of multiple drainage cycles constitutes the drainage time in this embodiment. This embodiment does not specifically limit the first drainage cycle and the first drainage duration. The washing machine can flexibly adjust the drainage cycle and drainage duration according to the actual water level in the inner drum.

[0062] In the above-mentioned S30, "draining the load inside the washing machine drum according to the target drainage parameters until the spin-drying is completed" may further include:

[0063] S303, drain the load inside the washing machine drum according to the first drainage cycle and the first drainage time;

[0064] S304, Obtain the water level of the inner tank during a preset period within the first drainage time;

[0065] S305, if the water level in the inner tank during the preset time period is continuously higher than the preset water level threshold, then adjust the first drainage rhythm and the first drainage time, and count the number of drainage anomalies.

[0066] S306, Drainage is carried out according to the adjusted first drainage rhythm and the adjusted first drainage time until the dehydration stage ends, and / or the number of drainage abnormalities exceeds a preset threshold.

[0067] It should be noted that, in this embodiment, as Figure 3 As shown, when the washing machine drains the load inside the drum according to the first drainage cycle and the first drainage time, according to the above description, if the drain pump of the washing machine experiences air binding, and the drain pump is always at an inappropriate start-stop cycle, it will cause the drain pump to fail to drain water, which will lead to the washing machine's spin-drying failure and drying failure, seriously reducing the washing performance of the washing machine and seriously affecting the user experience.

[0068] Therefore, in this embodiment, as Figure 3As shown, when draining the load inside the tank according to the first drainage cycle and the first drainage time, the water level in the inner tank at a preset time within the first drainage cycle can be obtained. This preset time can be the moment before the end of the first drainage time. For example, if the first drainage cycle is 20 seconds on and 2 seconds off, and the first drainage time is the duration of three first drainage cycles, i.e., 66 seconds, then the preset segment can be 5 seconds before the end of the first drainage time. If the water level in the inner tank remains higher than the preset water level threshold during this 5-second period, then... Figure 3 As shown, this indicates that the current drainage cycle setting is unreasonable and needs to be adjusted. The washing machine can adjust the first drainage cycle and the first drainage time, and count the number of drainage anomalies.

[0069] Specifically, for example, such as Figure 3 As shown, if no high water level is continuously detected within 5 seconds, it indicates that the current drainage rhythm setting is reasonable. This rhythm (20 seconds on, 2 seconds off) can be recorded, and the process can be returned to the beginning. The process can then continue with the 20-second on, 2-second off rhythm for 3 cycles while continuously detecting the water level signal. This cycle can be repeated. If a high water level is continuously detected within 5 seconds, it indicates that the current drainage rhythm setting is unreasonable. The number of drainage anomalies is recorded as 1, and the first drainage rhythm and the first drainage time are adjusted. For example, the process can be switched to the second rhythm (20 seconds on, 4 seconds off) and the water level signal can be detected and judged according to the above method. If a good drainage effect is not achieved, the process can be switched to the third rhythm (20 seconds on, 6 seconds off). If a good drainage effect is achieved, this rhythm can be recorded, and the process can be returned to the beginning to drain water according to the current rhythm (20 seconds on, 4 seconds off).

[0070] Through the above-described cycle, this embodiment can continuously attempt various drainage rhythms and drainage times multiple times until the spin-drying stage ends and / or the number of drainage anomalies exceeds a preset threshold. When the number of drainage anomalies exceeds the preset threshold, the washing machine can issue a drainage anomaly alarm, reminding the user that the drain pump may be clogged due to dirt or large objects, requiring contact with the manufacturer for inspection and repair. The number of drainage anomalies can be reset to zero when the washing program ends, the machine is turned off, or a program is switched. When the program is restarted, the count will be reset. It is worth noting that since a program often involves multiple drainage cycles, the accumulated number of anomaly alarms is shared across multiple cycles. For example, if the preset threshold is 3 times, and a drainage anomaly occurs once during the main wash stage, a maximum of two drainage anomalies are allowed during the rinsing stage.

[0071] Therefore, in this embodiment, the washing machine can perform a defoaming operation when there is a lot of foam in the drum, and use a corresponding drainage rhythm and duration during the spin-drying stage to drain the water, effectively improving the defoaming and drainage effects, reducing the probability of repeatedly triggering the defoaming operation, and saving washing time, water, and electricity. In addition, this embodiment can try different drainage rhythms multiple times when the water level in the drum is high, effectively preventing air binding and ensuring drainage effectiveness. This achieves complete drainage of the washing machine, further mitigating the triggering of defoaming and spin-drying with water remaining, and avoiding subsequent spin-drying and drying failures. Furthermore, since the washing machine can try different drainage strategies multiple times, this embodiment eliminates the need for drainage tests under various conditions during the product development stage, shortening the development cycle and reducing problems caused by insufficient experience.

[0072] In one embodiment, in S20 above, "obtaining the target drainage parameters of the washing machine based on the actual water level and the preset defoaming water level, and the actual motor power and the preset spin-drying power threshold" may include:

[0073] S203, if the actual water level does not exceed the preset defoaming water level and the actual motor power exceeds the preset dehydration power threshold, then obtain the target average motor power and maximum motor power of the motor within the second preset time period.

[0074] S204, based on the target average motor power, the maximum motor power, and the preset power range, obtain the second target drainage parameters of the washing machine.

[0075] In this embodiment, if the washing machine determines that the actual water level in the inner tub does not exceed the preset defoaming water level and the actual motor power exceeds the preset spin-drying power threshold, it means that the washing machine is experiencing a spin-drying phenomenon with water remaining. As explained above, the motor power during a spin-drying process with water remaining is much higher than the maximum motor power under normal clothing spin-drying conditions. Therefore, if... Figure 4 As shown, the washing machine can obtain the target average motor power and maximum motor power of the motor within a second preset time period.

[0076] For example, such as Figure 4 As shown, when the actual motor power exceeds the preset spin-drying power threshold, the washing machine can record the motor power every 0.1 seconds, time it for 3 seconds (i.e., the second duration), and calculate the target average motor power corresponding to 30 power values ​​within those 3 seconds, as well as the maximum motor power among the 30 power values.

[0077] Furthermore, the washing machine can obtain its second target drainage parameters based on the aforementioned target average motor power, maximum motor power, and preset power range.

[0078] Specifically, in S204 above, "obtaining the second target drainage parameters of the washing machine based on the target average motor power, the maximum motor power, and the preset power range" may include:

[0079] S2041, obtain the first target power range corresponding to the target average motor power and the second target power range corresponding to the maximum motor power;

[0080] S2042, based on the first target power range and the second target power range, obtain the second drainage parameters, wherein the second drainage parameters include: the second drainage cycle and the second drainage time;

[0081] In this embodiment, when the actual water level does not exceed the preset defoaming water level and the actual motor power exceeds the preset spin-drying power threshold, the washing machine can obtain a first target power range corresponding to the target average motor power and a second target power range corresponding to the maximum motor power.

[0082] Furthermore, such as Figure 4 As shown, the washing machine can obtain the second drainage parameters based on the first target power range and the second target power range.

[0083] Specifically, for example, as explained above, different water level ranges have corresponding drainage cycles and drainage times. Similarly, different power ranges also have corresponding drainage cycles and drainage times. Based on this, when the first target power range and the second target power range intersect, the washing machine can obtain the drainage parameters corresponding to the intersection range as the second drainage parameters. Alternatively, when the first target power range and the second target power range do not intersect, the washing machine can obtain the drainage parameters corresponding to the first target power range as the second drainage parameters.

[0084] In this embodiment, the second drainage parameter may include: a second drainage cycle time and a second drainage time, such as... Figure 4 As shown, the second drainage parameter may also include the drainage settling time.

[0085] Based on this, in S30 above, "draining the load inside the washing machine drum according to the target drainage parameters" may include:

[0086] S307, control the motor to stop, and perform static treatment on the load in the tank according to the drainage static time;

[0087] S308, drain the load inside the bucket after static treatment according to the first drainage cycle and the first drainage time.

[0088] In this embodiment, as Figure 4As shown, after obtaining the second drainage cycle, second drainage time, and drainage settling time corresponding to the power range, the washing machine can perform settling treatment on the load inside the drum according to the drainage settling time, allowing the remaining water inside the washing machine to collect in the inner drum. Then, the washing machine can drain the load inside the drum after the settling treatment according to the second drainage cycle and second drainage time, alleviating the phenomenon of water-laden spin-drying and reducing motor power.

[0089] It is worth noting that in this embodiment, when draining the load inside the tank according to the second drainage rhythm and the second drainage time, the influence of air binding on the drainage effect should also be considered. That is, it can be done according to... Figure 3 The drainage cycle switching strategy shown continuously tries various drainage cycles and drainage times multiple times until the dehydration stage ends and / or the number of drainage abnormalities exceeds a preset threshold. When the number of drainage abnormalities exceeds the preset threshold, the washing machine can issue a drainage abnormality alarm. This will not be elaborated further here, but you can refer to the specific implementation of the above embodiments.

[0090] Therefore, in this embodiment, if water is detected during the spin-drying process of the washing machine, the motor can be stopped, and the water can be drained after the machine has been left to stand. The spin-drying process can then resume after the water drains normally, until the spin-drying is finished. This effectively alleviates the problem of water being trapped in the washing machine, avoids abnormal increases in motor power, improves the spin-drying effect of the washing machine, and enhances the performance of the washing machine.

[0091] In one embodiment, in S20 above, "obtaining the target drainage parameters of the washing machine based on the actual water level and the preset defoaming water level, and the actual motor power and the preset spin-drying power threshold" may include:

[0092] S205, if the actual water level exceeds the preset defoaming water level and the actual motor power exceeds the preset dehydration power threshold, then obtain the water level difference between the actual water level and the preset defoaming water level, and the power difference between the actual motor power and the preset dehydration power threshold.

[0093] S205, based on the water level difference and the power difference, obtain the drainage priority, and obtain the target drainage parameters corresponding to the drainage priority.

[0094] In this embodiment, if the washing machine determines that the actual water level in the inner tub exceeds the preset defoaming water level and the actual motor power exceeds the preset spin-drying power threshold, it means that there is both excessive foam and spin-drying with water. At this time, the water level difference between the actual water level and the preset defoaming water level, as well as the power difference between the actual motor power and the preset spin-drying power threshold, can be obtained.

[0095] Therefore, the washing machine can determine the drainage priority based on the aforementioned water level difference and power difference.

[0096] Specifically, for example, the washing machine can calculate a first ratio between the water level difference and the actual water level, and a second ratio between the power difference and the actual motor power. Based on the relationship between the first and second ratios, a drainage priority can be set. For instance, if the first ratio is greater than the second ratio, a corresponding drainage priority can be obtained, such as prioritizing defoaming treatment. Furthermore, the washing machine can obtain the target average water level for a first preset time from the information on changes in the actual water level in the inner tub, and based on this target average water level and the preset water level range, obtain the washing machine's load spray duration, defoaming settling time, first drainage cycle time, and the second... The washing machine drains water using target drainage parameters such as drainage time, and then checks again whether the actual motor power exceeds the preset spin-drying power threshold. For example, if the first ratio is less than the second ratio, the corresponding drainage priority can be obtained. In this case, the drainage priority can be to perform spin-drying with water first. Then, the washing machine can obtain the target average motor power and maximum motor power within a second preset time period, and based on the target average motor power, maximum motor power, and preset power range, obtain the target drainage parameters such as the second drainage cycle, second drainage time, and drainage settling time of the washing machine for drainage, and then check again whether the actual water level exceeds the preset defoaming water level.

[0097] Therefore, in this embodiment, if the washing machine detects both excessive foam in the inner tub and the phenomenon of spin-drying with water, it can prioritize addressing the issue that has a greater impact on the washing machine's performance. This can effectively improve the defoaming and drainage effects, reduce the probability of repeatedly triggering the defoaming program, save washing time and water and electricity consumption, and also improve drainage efficiency under the condition of spin-drying with water, thereby improving the washing machine's performance from multiple dimensions.

[0098] This embodiment also provides a drainage control device, which can be integrated into a terminal device, for example, such as... Figure 5 As shown, the drainage control device may include:
