Description

Technical Field

[0001] The present application relates to the field of washing machines, and in particular to a control method, electronic device and washing machine for washing machines. Background Art

[0002] Rinsing is one of the main procedures of a washing machine, which uses the rinse water to remove residual additives and other substances on the clothes. Spray rinsing is a rinsing method. During spray rinsing, clean water needs to be sprayed towards the clothes. The clean water mixes with the residual additives and other substances on the clothes to form sewage. At the same time, the clothes must be rotated at high speed. In this way, the sewage is separated from the clothes and discharged under the high-speed rotation of the clothes. Taking a drum washing machine as an example, since the clothes need to be rotated at high speed during the spray rinsing process, it is difficult to maintain the stability of high-speed rotating clothes. They will hit the door and the mouth of the washing tub, generating noise and vibration, affecting the user's experience of using the washing machine. Summary of the Invention

[0054] According to a third aspect of an embodiment of the present application, a washing machine is provided, which is used to execute any one of the above-mentioned washing machine control methods, or includes the above-mentioned electronic device.

[0055] The solution provided by the present invention has the following beneficial effects compared with the prior art:

[0056] Through the above technical solution, when the control method of the present application is applied to a drum washing machine, before the spray rinsing process is performed, the washing tub first performs the clothes-adhering stage, so that the clothes can stick to the inner wall of the washing tub. After the clothes-adhering stage is performed, the clothes stick to the inner wall of the washing tub. When the spray rinsing stage is performed again, the clothes will not hit the door body and the drum mouth of the washing tub due to the high-speed rotation, thereby avoiding the generation of noise and vibration, and ensuring the user's experience of using the washing machine. At the same time, due to the different weights of the clothes and the different water absorption of the clothes each time they are washed, the moisture content of the clothes after dehydration is also different. Clothes with strong water absorption are less likely to stick to the inner wall of the washing tub and will hit the door body and the drum mouth of the washing tub, generating noise and vibration. To ensure that the clothes adhere closely to the inner wall of the washing tub after the clothes adhere stage, the washing tub rotation speed and time during the clothes adhere stage are adjusted based on the weight of the clothes and the weight of the clothes after dehydration. This ensures that clothes of different weights and different water absorbencies adhere closely to the inner wall of the washing tub during the clothes adhere stage. Furthermore, during the spray rinsing stage, clothes of different weights require different degrees of rinsing. Therefore, before each spray rinsing cycle, the washing tub rotation speed and time during the spray rinsing stage are adjusted based on the weight of the clothes. This ensures that the clothes are rinsed cleanly while avoiding energy waste. Furthermore, the second rotation speed requires the first rotation speed to ensure that during the spray rinsing stage, the clean water has sufficient time to mix with residual additives and other substances on the clothes, ensuring a clean clothes effect and ensuring that the clothes remain closely attached to the inner wall of the washing tub during the spray rinsing stage.

[0057] Other features and advantages of the present disclosure will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0062] It should be understood that the "plurality" mentioned herein refers to two or more. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art will understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit them to be different.

[0063] In addition, the terms "comprises" and "having" and any variations thereof are intended to cover a non-exclusive inclusion. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0064] Spray rinsing is a rinsing method that involves spraying clean water onto the clothes. This water mixes with residual additives and other substances on the clothes to form wastewater. At the same time, the clothes are kept spinning at high speed, allowing the wastewater to escape and be discharged. For example, in drum washing machines, the high-speed rotation of the clothes during spray rinsing is difficult to maintain stability, causing them to slap against the door and the mouth of the washing tub, generating noise and vibration that affects the user experience.

[0065] Different types of clothing have different water absorption properties. Since a spray-type rinse is used, where water is drawn in and drained out simultaneously, these highly absorbent clothing items are less likely to stick to the inner wall of the washing tub during the spray-rinsing process. As a result, they will slap against the door and the opening of the washing tub during rotation, causing noise and vibration. Furthermore, large amounts of clothing and heavier clothing also have difficulty sticking to the inner wall of the washing tub during the spray-rinsing process. Heavier clothing requires a higher rotational speed to generate greater centrifugal force in order to adhere to the inner wall of the washing tub. When a large number of clothing items are pressed one on top of another, a higher rotational speed is also required to generate a greater centrifugal force in order to keep all clothing items pressed against the inner wall of the washing tub. Therefore, the clothing items will slap against the door and the opening of the washing tub during rotation, causing noise and vibration.

[0066] According to the first aspect of the embodiment of the present disclosure, Figure 1 and Figure 2 As shown, a control method for a washing machine is provided, wherein the washing machine includes a washing tub and a spray device, and the method includes:

[0067] In step S100, the weight M1 of the laundry is obtained, so that the rotation speed and running time of the washing tub can be adjusted according to the weight M1 during the laundry sticking stage and the spray rinsing stage mentioned below.

[0068] In step S200, the weight M2 of the laundry after the washing stage and the first dehydration stage is obtained. In this way, the rotation speed and the running time of the washing tub can be further adjusted according to the weight M2 and the weight M1 during the laundry sticking stage.

[0069] In step S300, based on weights M1 and M2, the washing tub is controlled to execute a clothes-adhering stage. During this stage, the washing tub operates at a first speed for a first time. This stage is used to keep the clothes close to the inner wall of the washing tub. After the clothes-adhering stage, the clothes are closely attached to the inner wall of the washing tub. During the spray and rinse stage, the clothes do not slap against the door or the opening of the washing tub due to high-speed rotation, thus avoiding noise and vibration and ensuring a pleasant user experience.

[0070] After the washing tub runs for the first operating time, step S400 controls the washing tub to execute a spray-rinsing phase based on weight M1. During the spray-rinsing phase, the washing tub runs at a second speed for a second operating time. During the spray-rinsing phase, the spray device is controlled to be turned on, and the drain of the washing machine is controlled to be opened. The first speed is greater than the second speed. This allows the laundry to adhere to the inner wall of the washing tub during the spray-rinsing phase, preventing the laundry from slapping against the door or the opening of the washing tub due to the high-speed rotation.

[0071] Through the above technical solution, when the control method of the present application is applied to a drum washing machine, before the spray rinsing process is performed, the washing tub first performs the clothes-adhering stage, so that the clothes can stick to the inner wall of the washing tub. After the clothes-adhering stage is performed, the clothes stick to the inner wall of the washing tub. When the spray rinsing stage is performed again, the clothes will not hit the door body and the drum mouth of the washing tub due to the high-speed rotation, thereby avoiding the generation of noise and vibration, and ensuring the user's experience of using the washing machine. At the same time, due to the different weights of the clothes and the different water absorption of the clothes each time they are washed, the moisture content of the clothes after dehydration is also different. Clothes with strong water absorption are less likely to stick to the inner wall of the washing tub and will hit the door body and the drum mouth of the washing tub, generating noise and vibration. To ensure that the clothes adhere closely to the inner wall of the washing tub after the clothes adhere stage, the washing tub rotation speed and time during the clothes adhere stage are adjusted based on the weight of the clothes and the weight of the clothes after dehydration. This ensures that clothes of different weights and different water absorbencies adhere closely to the inner wall of the washing tub during the clothes adhere stage. Furthermore, during the spray rinsing stage, clothes of different weights require different degrees of rinsing. Therefore, before each spray rinsing cycle, the washing tub rotation speed and time during the spray rinsing stage are adjusted based on the weight of the clothes. This ensures that the clothes are rinsed cleanly while avoiding energy waste. Furthermore, the second rotation speed requires the first rotation speed to ensure that during the spray rinsing stage, the clean water has sufficient time to mix with residual additives and other substances on the clothes, ensuring a clean clothes effect and ensuring that the clothes remain closely attached to the inner wall of the washing tub during the spray rinsing stage.

[0072] It should be noted that the clothes mentioned above and below refer to all the clothes in the washing tub during a single wash in a washing machine, and the units of weight M1 and weight M2 are kg respectively. At the same time, the control method of the washing machine in this application is not limited to application to drum washing machines. In addition to drum washing machines, it can also be applied to other types of washing machines such as pulsator washing machines or agitator washing machines. This application does not make specific limitations on this. At the same time, in order to more clearly describe this application, the control method of the washing machine in this application is described as an example when it is applied to a drum washing machine.

[0073] During the spray-rinsing phase of the washing tub, due to uneven forces on the washing tub, the clothing in the washing tub may still slap against the door, the tub opening, and other structures, causing noise and vibration, which may affect the user experience. The washing machine includes a motor for driving the washing tub. Therefore, in some embodiments, the method may further include: Step S500: obtaining the rated power fluctuation W1 of the motor based on the weight M1; Step S600: obtaining the real-time power fluctuation W2 of the motor during the spray-rinsing phase of the washing tub; and Step S700: determining whether to insert an intermediate spin stage during the spray-rinsing phase based on the rated power fluctuation W1 and the real-time power fluctuation W2. During the spray-rinse cycle, when clothing in the washing tub slaps or rubs against the door, the tub opening, and other structures, the power of the motor driving the tub can change. Large fluctuations in the motor's power indicate that the washing machine is about to or has already experienced unusual noise, vibration, or other issues during the spray-rinse cycle. By using the rated power fluctuation W1 and the motor's real-time power fluctuation W2, the washing machine can be monitored during the spray-rinse cycle to prevent noise, vibration, and other issues. Furthermore, if unusual noise, vibration, or other issues are about to or have already occurred during the spray-rinse cycle, an intermediate spin cycle can be inserted to promptly stop the spray-rinse cycle and prevent the occurrence or continuation of these issues. It should be noted that the motor's real-time power fluctuation W2 mentioned above refers to the difference between the maximum and minimum power values ​​detected during multiple motor power tests within a certain time period. This is the motor's real-time power fluctuation W2. The number of times the motor power is detected within a certain time period can be determined according to the type of washing machine and actual usage. Generally speaking, the motor power can be obtained once per second within a certain time period and the real-time power fluctuation W2 is calculated.

[0074] Step S600 may include step S601: while the spray device is on, obtaining real-time power fluctuations W2 of the motor within a first time period. The first time period can be set based on actual usage needs. The shorter the first time period, the more frequent the monitoring of the washing machine during the spray and rinse phases, making it easier to detect abnormal sounds, noises, and vibrations that are about to or have already occurred during the spray and rinse phases. Generally, the first time period can be between 2 seconds and 30 seconds.

[0075] It should be noted that, in the first time period herein, there are multiple first time periods within the second operating time. For example, when the first time period is 2 seconds and the second operating time is 120 seconds, there are 60 first time periods within the second operating time. When the control method of the present application is applied, it is necessary to obtain the real-time power fluctuation W2 of the motor within each first time period for each first time period. Based on the real-time power fluctuation W2 within each first time period, the washing tub is controlled to continue the spray and rinse phase or the washing machine is controlled to re-execute the spray and rinse phase within each first time period. Continuing with the example of a first time period of 2 seconds and obtaining the motor power once per second and calculating the real-time power fluctuation W2, the real-time power of the motor is obtained once in the first second and once in the second second. The difference between the two real-time powers is the real-time power fluctuation W2 of the motor within the first first time period. The real-time power of the motor is obtained once in the third second and once in the fourth second. The difference between the two real-time powers is the real-time power fluctuation W2 of the motor within the second first time period.

[0076] Step S700 may include step S701: when the real-time power fluctuation W2 is less than the rated power fluctuation W1, controlling the washing tub to continue the spray-rinsing stage without inserting the intermediate spin stage; when the real-time power fluctuation W2 is greater than or equal to the rated power fluctuation W1, inserting the intermediate spin stage and, after the intermediate stage is executed, re-executing the spray-rinsing stage, wherein, during the intermediate spin stage, the spray device is controlled to be turned off, and the washing tub is controlled to operate at a third speed for a third operating time based on the weight M1, wherein the third speed is greater than the second speed. When the real-time power fluctuation W2 is less than the rated power fluctuation W1, it indicates that the motor power has not significantly changed, the clothes in the washing tub are still in a relatively stable state, and no vibration or abnormal noise is generated, and the washing tub continues to execute the spray-rinsing stage. When the real-time power fluctuation W2 is greater than the rated power fluctuation W1, it means that the clothes in the washing tub are not stable enough, and there are flapping and friction phenomena with the door body and the barrel mouth of the washing tub. At this time, an intermediate dehydration stage is inserted. According to the weight M1, the washing tub is controlled to run at the third speed for the third running time, and then the washing machine is controlled to re-execute the spray rinsing stage. It should be noted that when the washing tub is controlled to run at the third speed for the third running time, the drain port of the washing machine is still open to ensure that the water on the clothes can be drained, so that the clothes can be restored to the state after dehydration, which is convenient for the washing machine to re-execute the spray rinsing stage. The re-execution of the spray rinsing stage mentioned here refers to the washing machine re-executing step 400 after the intermediate dehydration stage is completed, that is, after the intermediate dehydration stage is completed, according to the weight M1, the washing tub is controlled to execute the spray rinsing stage and run at the second speed for the second running time.

[0077] During the spray and rinse phase, the weight of the laundry changes. The more laundry, the heavier it is, and the more water it absorbs. Therefore, when the washing tub is controlled to perform the intermediate spin phase, the laundry needs to be restored to the state before the spray and rinse phase. To minimize noise and vibration, the required spin speed of the washing tub increases as the weight M1 increases during the intermediate spin phase. In some embodiments, in step 701, when the weight M1 is within a first preset range, the third spin speed is controlled to be 2 times the first spin speed; or when the weight M1 is within a second preset range, the third spin speed is controlled to be 1.5 times the first spin speed; or, when the weight M1 is within a third preset range, the third spin speed is controlled to be 1 times the first spin speed. The weights of the first, second, and third preset ranges increase in sequence, and the third run time is a fixed duration. Since the clothes still need to be re-executed with the spray and rinse program, in order to save energy by restoring the clothes to the state before the spray and rinse stage, as the weight of the clothes increases, the ratio of the third speed to the first speed gradually decreases. At the same time, the third running time can be a fixed length, for example, 30 seconds. This ensures that the clothes can be restored to the state before the spray and rinse stage is executed while ensuring that energy is not wasted.

[0078] It should be noted that due to the different types and sizes of washing machines, the weights of clothes that a washing machine can handle also vary. The first, second, and third preset ranges herein are three weight ranges of increasing weight, designed to adapt to the weight of clothes that the washing machine can handle. This allows the control method in this application to perform different controls for clothes of different weights, ensuring the effectiveness of the washing machine while also avoiding energy waste. Correspondingly, the first, second, and third preset ranges can also be designed to be adaptive based on the weight of clothes that the washing machine can handle. In this regard, this application does not specifically limit the first, second, and third preset ranges.

[0079] The motor requires different rated power to drive clothes of different weights through the spray-rinse cycle. Therefore, in some embodiments, step 500 may further include step 501: when weight M1 is within a first preset range, 100W ≤ W1 ≤ 150W; or when weight M1 is within a second preset range, 150W < W1 ≤ 200W; or, when weight M1 is within a third preset range, 200W < W1 ≤ 250W; wherein the weights of the first, second, and third preset ranges increase in sequence. In this way, as weight M1 changes, W1 also changes, making it more accurate to determine whether the washing machine is about to or has already experienced abnormal sounds, noises, or vibrations during the spray-rinse cycle.

[0080] In step S300, the first rotational speed and first operating time of the washing tub during the clothing wall-adhering stage are determined based on the preset range of weight M1 and the ratio range of M2 / M1. If weight M1 falls within the same preset range, the larger the ratio range of M2 / M1, the longer the first rotational speed and first operating time. If M2 / M1 falls within the same ratio range, the larger the preset range of weight M1, the longer the first rotational speed and first operating time. As described above, the more laundry, the heavier the laundry, and the more water-absorbent the laundry, the higher the rotational speed and the longer the time required to keep the laundry in contact with the inner wall of the washing tub during the clothing wall-adhering stage. Conversely, a small amount of laundry is more likely to be completely adhered to the inner wall of the washing tub at a lower rotational speed. At the same time, different garments have different water absorption rates. M1 represents the weight of the garment when dry, while M2 represents its weight after dehydration. The ratio of the two can be used to determine a garment's water absorption. Generally speaking, garments with higher water absorption rates are bulky items, such as bath towels and quilts. These bulky items have difficulty adhering to the inner tub wall at low rotational speeds. In contrast, garments with lower water absorption rates, such as shirts, can adhere to the inner tub wall at low rotational speeds without interfering with the door seal or glass bowl. Therefore, the more absorbent the garment, the higher the speed and the longer the washing tub needs to maintain contact with the inner tub wall during the "closing" phase. This ensures that garments of varying weights and absorbencies can adhere to the inner tub wall during this phase.

[0081] In some embodiments, step S300 may include step S301: when the weight M1 is within a first preset range:

[0082] When M2 / M1≤1.2, the first speed is controlled to be 300prm-400prm, and the first running time is controlled to be 5s-10s; or when 1.2<M2 / M1≤1.5, the first speed is controlled to be 300prm-400prm, and the first running time is controlled to be 10s-15s; or when 1.5<M2 / M1, the first speed is controlled to be 300prm-400prm, and the first running time is controlled to be 15s-20s;

[0083] When the weight M1 is within the second preset range:

[0084] When M2 / M1≤1.2, the first speed is controlled to be 500prm-600prm, and the first running time is controlled to be 20s-25s; or when 1.2<M2 / M1≤1.5, the first speed is controlled to be 500prm-600prm, and the first running time is controlled to be 25s-30s; or when 1.5<M2 / M1, the first speed is controlled to be 500prm-600prm, and the first running time is controlled to be 30s-35s;

[0085] When the weight M1 is within the third preset range:

[0086] When M2 / M1 ≤ 1.2, the first speed is controlled to be 700-800rpm, and the first operation time is controlled to be 40s-45s; or when 1.2 < M2 / M1 ≤ 1.5, the first speed is controlled to be 700-800rpm, and the first operation time is controlled to be 45s-50s; or when 1.5 < M2 / M1, the first speed is controlled to be 700-800rpm, and the first operation time is controlled to be 50s-55s. In this way, as the weight of the laundry gradually increases, the first speed and first operation time required for the washing tub to perform the laundry sticking stage increase, and as the water absorption gradually increases, the first speed and first operation time required for the washing tub to perform the laundry sticking stage also increase. At the same time, it is also necessary to avoid the first speed and first running time required for the washing tub to execute the clothes sticking to the wall stage being too high or too low. When the first speed and first running time required for the washing tub to execute the clothes sticking to the wall stage are too low, the clothes may not stick to the inner wall of the washing tub. When the first speed and first running time required for the washing tub to execute the clothes sticking to the wall stage are too high, it will cause energy waste.

[0087] In step S400, controlling the washing tub to perform the spraying and rinsing stage according to the weight M1 includes: determining a second rotation speed and a second operating time of the washing tub in the spraying and rinsing stage according to the weight M1, wherein the greater the weight M1, the smaller the second rotation speed and the longer the second operating time; or

[0088] According to the weight M1, the washing tub is controlled to perform the spray rinsing phase including:

[0089] When the weight M1 is within the first preset range, the second speed is controlled to be 150prm-200prm, and the second running time is controlled to be 120s-180s;

[0090] Alternatively, when the weight M1 is within the second preset range, the second speed is controlled to be 100 prmm-150 prmm, and the second running time is controlled to be 240s-300s;

[0091] Alternatively, when the weight M1 is within the third preset range, the second rotational speed is controlled to be 60 rpm-100 rpm, and the second operating time is controlled to be 360 ​​s-420 s. When executing the spray-rinsing cycle, it is necessary to ensure a good rinsing effect on the clothes. The heavier the clothes, the more residual additives and other substances will remain on the clothes. To allow the clean water and residual additives and other substances on the clothes to mix and fully form sewage, it is necessary to ensure that the clean water and the clothes have sufficient contact time. Therefore, the heavier the clothes, the slower the second rotational speed required for the washing tub to execute the spray-rinsing cycle and the longer the second operating time, to ensure a good rinsing effect on the clothes. Because the washing tub needs to be continuously filled with water during the spray-rinsing cycle, the heavier the clothes, the less stable the washing tub is. Therefore, the heavier the clothes, the slower the second rotational speed required for the washing tub to execute the spray-rinsing cycle and the longer the second operating time, to ensure the stability of the washing tub during the spray-rinsing cycle.

[0092] In some embodiments, the method further includes step S800: performing a second spin cycle after the spray and rinse phase is completed. Thus, after the spray and rinse phase is completed, the washing machine can automatically enter the second spin cycle. After the second spin cycle, the clothes are cleaned and then spun dry, allowing the washing machine to directly complete the entire washing process without requiring the user to re-operate the washing machine, thereby facilitating use.

[0093] According to the second aspect of the embodiment of the present application, an electronic device is also provided, including a memory and a processor, the memory being used to store a computer program; the processor being used to execute the computer program to implement the steps of the washing machine control method of any of the above-mentioned embodiments. The electronic device has all the beneficial effects of the above-mentioned washing machine control method, which will not be repeated here.

[0094] According to the third aspect of the embodiment of the present application, a washing machine is provided, which is used to execute any of the above-mentioned washing machine control methods, or includes the above-mentioned electronic device, and has all the beneficial effects of the above-mentioned washing machine control methods, which will not be repeated here.

[0095] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
