Description

Technical Field

[0001] This invention relates to the field of smart home appliance technology, specifically providing a method for correcting imbalances in washing equipment. Background Technology

[0002] Washing machines are common household laundry appliances. Based on their washing methods, washing machines can be broadly classified into top-loading (pulsator) washing machines and front-loading (drum) washing machines. Taking a top-loading washing machine as an example, during the washing and rinsing operations, it generally uses alternating forward and reverse rotation to wash or rinse clothes. This method causes the clothes to tangle together and become unevenly distributed within the drum. When the washing machine performs the spin-drying operation, the unevenly distributed clothes generate asymmetrical centrifugal forces on the drum, causing it to shake violently due to uneven force distribution. This results in the washing machine hitting the drum and producing noise.

[0003] To address the aforementioned issues, existing technologies incorporate an imbalance correction program in pulsator washing machines. When the washing machine experiences drum-collision, this program corrects the imbalance by filling the drum with water to the balanced level and executing a balancing water flow command to disperse and evenly distribute the clothes inside. However, drum-collision in pulsator washing machines can occur for many reasons. Using the same balancing operation for all causes may not achieve optimal balancing, and may also fail to effectively disperse and evenly distribute the clothes. For example, if the collision is caused by tangled clothes, the clothes are stuck to the inner wall of the drum, with little or no clothing in the center. In this case, directly filling the drum with water will not disperse or evenly distribute the clothes. Even after the balancing correction operation, the washing machine may still experience drum-collision during the spin-drying cycle, negatively impacting the user experience.

[0004] Therefore, there is a need in the art for a new method for correcting imbalances in washing equipment to address the aforementioned problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that the imbalance correction effect of existing washing equipment is not ideal.

[0006] This invention provides a method for correcting imbalance in a washing machine. The method includes the following steps: during the spin-drying process of the washing machine, determining whether the washing machine is experiencing a drum collision; if the washing machine is determined to have experienced a drum collision, obtaining the initial weight of the clothes in the washing drum of the washing machine; determining whether the initial weight is greater than a preset weight; and, based on the determination result, causing the washing machine to perform different balancing operations.

[0007] In the preferred embodiment of the above imbalance correction method, the step of "causing the washing equipment to perform different balancing operations according to the judgment result" specifically includes: if the initial weight is greater than the preset weight, then obtaining the type of clothes in the washing tub; determining the category to which the type belongs; and, based on the judgment result, causing the washing equipment to perform different balancing operations.

[0008] In the preferred embodiment of the above imbalance correction method, the step of "causing the washing equipment to perform different balancing operations based on the judgment result" specifically includes: if the type belongs to the first category, then causing the washing equipment to perform the first balancing operation.

[0009] In the preferred embodiment of the above-mentioned imbalance correction method, the step of "causing the washing equipment to perform a first balancing operation" specifically includes: filling the washing equipment with water to a first preset water level, wherein the first preset water level is lower than the rinsing water level of the washing equipment; after filling the washing equipment with water to the first preset water level, causing the washing equipment to perform a balancing operation according to a first water flow intensity.

[0010] In the preferred embodiment of the above-mentioned imbalance correction method, the step of "making the washing equipment perform different balancing operations based on the judgment result" further includes: if the type belongs to the second category, then making the washing equipment perform a second balancing operation.

[0011] In the preferred embodiment of the above-mentioned imbalance correction method, the step of "performing a second balancing operation" specifically includes: filling the washing equipment with water to a second preset water level, wherein the second preset water level is lower than the rinsing water level of the washing equipment; after filling the washing equipment with water to the second preset water level, performing a balancing operation according to a second water flow intensity; after performing a balancing operation according to the second water flow intensity, continuing to fill the washing equipment with water to the rinsing water level; during the process of continuing to fill the washing equipment with water to the rinsing water level, performing a balancing operation according to a third water flow intensity; and after filling the washing equipment with water to the rinsing water level, performing a balancing operation according to a fourth water flow intensity.

[0012] In the preferred embodiment of the above-mentioned imbalance correction method, the third water flow intensity includes a forward water flow intensity and a reverse water flow intensity, wherein the first rotation time of the forward water flow intensity and the second rotation time of the reverse water flow intensity are different from each other; the step of "making the washing equipment perform a balancing operation according to the third water flow intensity" specifically includes: making the washing equipment operate alternately according to the forward water flow intensity and the reverse water flow intensity.

[0013] In the preferred embodiment of the above-mentioned imbalance correction method, the third water flow intensity is greater than the fourth water flow intensity; and / or the fourth water flow intensity is greater than the second water flow intensity.

[0014] In the preferred embodiment of the above-mentioned imbalance correction method, the step of "causing the washing equipment to perform different balancing operations according to the judgment result" further includes: if the initial weight is less than or equal to the preset weight, then causing the washing equipment to perform a third balancing operation.

[0015] In the preferred embodiment of the above-mentioned imbalance correction method, the step of "making the washing equipment perform a third balancing operation" specifically includes: making the washing equipment run alternately in forward and reverse directions.

[0016] In a preferred embodiment of the imbalance correction method of the present invention, during the spin-drying process of the pulsator washing machine, it is determined whether the pulsator washing machine has collided with the drum; if it is determined that the pulsator washing machine has collided with the drum, the initial weight of the clothes in the washing drum of the pulsator washing machine is obtained; it is determined whether the initial weight is greater than a preset weight; based on the determination result, the pulsator washing machine performs different balancing operations.

[0017] Compared to existing technologies that use the same balancing operation for all types of drum collisions, this invention, when a drum collision occurs in a pulsator washing machine, obtains the initial weight of the clothes. Based on whether the initial weight of the clothes is greater than a preset weight, it can accurately determine the cause of the drum collision and accurately determine different balancing operations based on the cause. This allows the pulsator washing machine to perform an effective balancing operation, effectively scattering and shaking the clothes, ensuring even distribution of the clothes in the washing tub. This avoids drum collisions during the spin-drying operation after the balancing operation, achieving the goal of providing the most suitable and effective balancing operation for the pulsator washing machine, thereby improving the user experience.

[0018] Furthermore, if the initial weight of the clothes is greater than the preset weight, it indicates that the weight of the clothes being washed is relatively heavy or that there are a large number of clothes. This could be due to the clothes tangling and causing the clothes to collide with the drum, or it could be due to uneven distribution of the clothes. In order to accurately determine the cause of the collision, the type of clothes in the washing tub of the pulsator washing machine is obtained. Based on the judgment result of the type of clothes, the cause of the collision in the pulsator washing machine can be determined more accurately. This allows for a more accurate determination of different balancing operations, enabling the pulsator washing machine to perform effective balancing operations. This effectively disperses and shakes the clothes, ensuring that the clothes are evenly distributed in the washing tub, further improving the user experience.

[0019] Furthermore, if the type of clothing belongs to the first category, it indicates that this type of clothing is not easy to tangle. It can be determined that the drum collision is caused by uneven distribution of clothing. In this case, the pulsator washing machine will perform the first balancing operation to address the cause of the drum collision, so that the clothing is evenly distributed in the washing drum, further improving the user experience.

[0020] Furthermore, if the type of clothing belongs to the second category, it indicates that this type of clothing is prone to tangling. It can be determined that the drum collision is caused by the tangled clothing. In this case, the pulsator washing machine will perform a second balancing operation to address the cause of the drum collision, which can effectively disperse and shake the clothing evenly, thereby improving the user experience.

[0021] Furthermore, if the initial weight of the clothes is less than or equal to the preset weight, it means that the weight of the clothes being washed is light or the quantity of clothes is small. This is likely due to the drum collision caused by eccentricity. In this case, the pulsator washing machine will perform a third balancing operation to address the cause of the drum collision, thereby eliminating the eccentricity and further improving the user experience.

[0029] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although this application is described in conjunction with a pulsator washing machine, the technical solution of the present invention is not limited thereto. In practical applications, the washing equipment can also be any type of washing equipment such as a pulsator washer-dryer combo or a pulsator shoe washer.

[0030] It should be noted that in the description of this invention, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the term "setup" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] Based on the technical problems mentioned in the background art, the present invention provides an imbalance correction method for a pulsator washing machine. The method aims to determine the initial weight of the clothes when the pulsator washing machine experiences drum collision, and accurately determine the cause of the drum collision based on whether the initial weight of the clothes is greater than a preset weight. Furthermore, it accurately determines different balancing operations based on the cause of the drum collision, enabling the pulsator washing machine to perform an effective balancing operation. This effectively disperses and shakes the clothes, ensuring even distribution within the washing tub. It avoids drum collisions during the subsequent spin-drying operation after the balancing operation, achieving the goal of providing the most suitable and effective balancing operation for the pulsator washing machine, thereby improving the user experience.

[0033] First see Figure 1 The imbalance correction method of the present invention will be described. Figure 1 This is the main flowchart of the imbalance correction method of the present invention.

[0034] like Figure 1 As shown, the imbalance correction method of the present invention includes the following steps:

[0035] S100. During the spin-drying process of the pulsator washing machine, determine whether the pulsator washing machine has experienced a drum collision.

[0036] S200: In the event that the pulsator washing machine has collided with the drum, obtain the initial weight of the clothes in the washing drum of the pulsator washing machine.

[0037] S300: Determine if the initial weight is greater than the preset weight;

[0038] S400: Based on the judgment result, the pulsator washing machine performs different balancing operations.

[0039] The spin-drying program of a pulsator washing machine includes a low-speed spin-drying stage, a high-speed spin-drying stage, a slow spin-drying stage, and a braking stage.

[0040] In step S100, during the low-speed spin-drying stage of the pulsator washing machine, it is determined whether the pulsator washing machine has experienced a drum collision.

[0041] Furthermore, the specific method for determining whether a top-loading washing machine has experienced a drum collision can be as follows: obtain the status of the safety switch, which includes both the open and closed states of the safety switch; determine whether the safety switch is open; if the safety switch is open, it indicates that the outer tub collided with the control lever of the safety switch, causing the safety switch to open, and thus the top-loading washing machine is determined to have experienced a drum collision; if the safety switch is not open, it indicates that the outer tub did not collide with the control lever of the safety switch, and the safety switch is in the closed state, and thus the top-loading washing machine is determined not to have experienced a drum collision.

[0042] Alternatively, in an alternative approach, the specific method for determining whether a pulsator washing machine has collided with the outer tub can be: obtaining a first eccentricity value of the outer tub; determining whether the first eccentricity value of the outer tub is greater than or equal to a first preset eccentricity threshold; if the first eccentricity value is greater than or equal to the first preset eccentricity threshold, it indicates that the eccentricity of the outer tub is large, causing the outer tub to collide with the control lever or the casing, and thus the pulsator washing machine is determined to have collided with the outer tub; if the first eccentricity value is less than the first preset eccentricity threshold, then the pulsator washing machine is determined not to have collided with the outer tub, where the first eccentricity threshold is the minimum eccentricity value of the outer tub used to determine whether the outer tub of the pulsator washing machine has collided with the control lever or the casing.

[0043] Alternatively, in another alternative approach, the specific method for determining whether a pulsator washing machine has experienced a drum collision can be: obtaining a second eccentricity value of the inner drum's rotation; determining whether the second eccentricity value is greater than or equal to a second preset eccentricity threshold; since the relative position between the inner and outer drums is fixed, the outer drum shifts with the inner drum's offset; when the second eccentricity value is greater than or equal to the second preset eccentricity threshold, it indicates that the inner drum's rotational eccentricity is large, and the inner drum will cause the entire washing tub to collide with the control lever or the cabinet; when the second eccentricity value is less than the second preset eccentricity threshold, it is determined that the pulsator washing machine has not experienced a collision. The second eccentricity threshold is the minimum rotational eccentricity value of the inner drum that causes the entire washing tub to collide with the control lever or the cabinet.

[0044] Of course, determining whether a top-loading washing machine has experienced a drum collision is not limited to the three methods listed above. Another method is to collect the instantaneous noise level generated by the washing machine during the spin cycle and determine if this instantaneous noise level is greater than or equal to a preset noise threshold. If the instantaneous noise level is greater than or equal to the preset noise threshold, it indicates that the outer tub has collided with the control lever or the machine body, producing significant noise, thus indicating a drum collision. If the instantaneous noise level is less than the preset noise threshold, it is determined that the washing machine has not experienced a drum collision. The preset noise threshold is the minimum noise level produced by the washing machine that indicates a drum collision, for example, 80 decibels. Regardless of the situation, as long as it can be determined that the washing machine has experienced a drum collision, it is considered valid.

[0045] In step S200, the initial weight of the garment is the weight measured when the garment is placed in the inner drum, i.e., the dry weight of the garment. The initial weight of the garment can be retrieved directly without weighing it again.

[0046] Furthermore, the weight of the clothes can be detected by the pulsator washing machine. For example, the weight can be obtained by using a weight sensor installed in the washing machine; or, after the drive motor of the pulsator washing machine rotates to a certain speed and then stops, the weight of the clothes can be estimated by reading the number of back electromotive force pulses generated by the drive motor. Of course, the initial weight of the clothes can also be input by the user. Regardless of the method used, as long as the initial weight of the clothes can be determined, it is acceptable.

[0047] The following reference Figures 2 to 5 The imbalance correction method of the present invention, which enables a pulsator washing machine to perform different balancing operations, is described herein. Figure 2 This invention describes a method for correcting imbalance in a pulsator washing machine by performing different balancing operations. Figure 1 ; Figure 3 This invention describes a method for correcting imbalance in a pulsator washing machine by performing different balancing operations. Figure 2 ; Figure 4 This is a flowchart of the imbalance correction method of the present invention for causing a pulsator washing machine to perform a first balancing operation; Figure 5 This is a flowchart of the imbalance correction method for causing a pulsator washing machine to perform a second balancing operation according to the present invention.

[0048] like Figure 2 As shown, step S400, "based on the judgment result, causing the pulsator washing machine to perform different balancing operations," specifically includes:

[0049] S411. If the initial weight is greater than the preset weight, obtain the type of clothes in the washing tub;

[0050] S412. Determine the category to which the type belongs;

[0051] S413. Based on the judgment result, the pulsator washing machine performs different balancing operations.

[0052] In step S411, if the initial weight is greater than the preset weight, for example, if the preset weight is 3kg and the initial weight of the clothes is 4kg, it means that the weight of the clothes being washed is heavy or the quantity of clothes is large. This may be due to the clothes tangling and causing the drum to collide, or it may be due to the uneven distribution of the clothes. In order to accurately determine the cause of the drum collision, the type of clothes is obtained so as to further determine the cause of the drum collision in the pulsator washing machine based on the type of clothes.

[0053] Furthermore, images of the clothing are acquired through image acquisition mechanisms such as cameras or webcams installed in the washing machine, and the type of clothing is determined based on the images. Alternatively, a preset model can be invoked to recognize the clothing images and identify the type of clothing. The preset model can be other models such as DeeplabV3+, ResNet101, CNN, ResNeXt, and HRNet. Regardless of the model used, the method for recognizing clothing images using any particular model should not constitute any limitation on this invention.

[0054] Alternatively, in an alternative implementation, using RFID identification technology as an example, step S411, the step of "obtaining the type of clothing," specifically includes:

[0055] The RFID tag information of the clothing is identified through the RFID identification module;

[0056] The type of clothing to be acquired is determined based on the RFID tag information identified by the RFID identification module.

[0057] The RFID tags on the clothing contain information such as the material, type, color, size, drying method, and washing method of the clothing.

[0058] It should be noted that the method for obtaining the type of clothing is not limited to the two methods listed above. The type of clothing can also be determined by identifying the NFC tag information of the clothing through the NFC identification module; or, the type of clothing can be determined by obtaining the user's voice information. Regardless of the method used to obtain the type of clothing, the specific implementation method corresponding to any method should not constitute a limitation on the present invention.

[0059] Preferably, the clothing types are categorized into a first category and a second category. The first category includes down jackets, short-sleeved shirts, vests, shorts, skirts, children's clothing, and other garments that are not easily tangled; the second category includes jeans, thick coats, skirts, curtains, bed sheets, duvet covers, and other garments that are easily tangled. The categorization of clothing types is not limited to the methods listed above; it can also be divided into three categories, four categories, etc. Those skilled in the art can flexibly adjust and set the categorization method according to actual usage needs. The control method of the present invention will be further illustrated below using the first and second categories as examples.

[0060] like Figure 3 As shown, step S413, "based on the judgment result, causing the pulsator washing machine to perform different balancing operations," specifically includes:

[0061] S421. If the type belongs to the first category, then cause the pulsator washing machine to perform the first balancing operation;

[0062] S422. If the type belongs to the second category, then the pulsator washing machine performs the second balancing operation.

[0063] In step S421, if the type of clothing belongs to the first category, it means that the clothing is down jacket, short sleeve, vest, shorts, short skirt, children's clothing, etc., which are not easy to tangle. Since such clothing is not easy to tangle, it can be determined that the drum collision is caused by uneven distribution of clothing. Then, the pulsator washing machine performs the first balancing operation for the cause of the drum collision, so that the clothing is evenly distributed in the washing drum, further improving the user experience.

[0064] Furthermore, such as Figure 4 As shown, step S421, the step of "causing the pulsator washing machine to perform the first balancing operation" specifically includes:

[0065] S431. Fill the pulsator washing machine with water to the first preset water level;

[0066] S432. After the pulsator washing machine is filled with water to the first preset water level, the pulsator washing machine performs a balancing operation according to the first water flow intensity.

[0067] The first preset water level is lower than the rinsing water level of the pulsator washing machine, and the rinsing water level is greater than or equal to the washing water level.

[0068] In step S431, the pulsator washing machine is controlled to fill water directly to the second water level. Of course, the pulsator washing machine can also be filled to the first water level, the third water level, or other water levels. No matter how the first preset water level is set, as long as the first preset water level is lower than the rinsing water level of the pulsator washing machine, it is acceptable.

[0069] In step S432, after the pulsator washing machine is filled with water to the second water level, it is equilibrated for 120 seconds according to the first preset water flow intensity, i.e., the drive motor's start-stop ratio is 1.1 / 0.8, to ensure that the clothes are evenly distributed in the washing tub. Of course, the first preset water flow intensity can also be other drive motor start-stop ratios such as 1.1 / 0.9 or 1.1 / 1.0, and the first equilibration time can also be any other time such as 60 seconds or 150 seconds.

[0070] Alternatively, in an alternative implementation, the washing machine may perform a balancing operation according to a first water flow intensity during the process of filling the washing machine with water to a first preset water level.

[0071] In step S422, if the type of clothing belongs to the second category, it means that the clothing is jeans, thick coats, skirts, curtains, sheets, duvet covers and other clothes that are easy to tangle. Since such clothes are easy to tangle, it can be determined that the drum collision is caused by the clothes tangling. Then the pulsator washing machine will perform the second balancing operation for the cause of the drum collision, which can effectively scatter and shake the clothes evenly, thereby improving the user experience.

[0072] Furthermore, such as Figure 5 As shown, step S422, the step of "causing the pulsator washing machine to perform the second balancing operation" specifically includes:

[0073] S441. Fill the pulsator washing machine with water to the second preset water level;

[0074] S442. After the pulsator washing machine is filled with water to the second preset water level, the pulsator washing machine performs a balancing operation according to the second water flow intensity.

[0075] S443. After the pulsator washing machine performs a balancing operation at the second water flow intensity, the pulsator washing machine continues to fill with water to the rinsing water level.

[0076] S444. While the pulsator washing machine continues to fill water to the rinsing water level, the pulsator washing machine performs a balancing operation according to the third water flow intensity.

[0077] S445. After the pulsator washing machine is filled with water to the rinsing water level, the pulsator washing machine performs a balancing operation according to the fourth water flow intensity.

[0078] Among them, the second preset water level is lower than the rinsing water level of the pulsator washing machine, and the rinsing water level is greater than or equal to the washing water level;

[0079] Among them, the third water flow intensity is greater than the fourth water flow intensity; the fourth water flow intensity is greater than the second water flow intensity.

[0080] In step S441, the washing machine is controlled to fill water directly to the second water level. Of course, it can also be filled to the first, third, or other water levels. Regardless of the setting of the second preset water level, it is acceptable as long as it is lower than the rinsing water level of the washing machine. It should be noted that although the listed second preset water level is the same as the first preset water level, in practical applications, the second preset water level can be set differently from the first preset water level.

[0081] In step S432, after the pulsator washing machine is filled with water to the second water level, it is equilibrated for 30 seconds according to the second preset water flow intensity, i.e., the drive motor's start-stop ratio is 1.0 / 0.8. This process shakes the clothes stuck to the inner wall of the washing tub as much as possible, allowing them to enter the center of the tub. The second preset water flow intensity can also be any other drive motor start-stop ratio, such as 1.0 / 0.9 or 0.9 / 0.8, as long as it is less than the fourth water flow intensity. The second equilibration time can be any other time, such as 20 seconds or 40 seconds. It should be noted that although the listed second preset water flow intensity is different from the first preset water flow intensity, in practical applications, the second preset water flow intensity can be set to be the same as the first preset water flow intensity.

[0082] Alternatively, in an alternative implementation, the washing machine may perform a balancing operation according to a second water flow intensity during the process of filling the washing machine with water to a second preset water level.

[0083] In steps S433 and S434, after the pulsator washing machine performs a balancing operation at the second water flow intensity, it continues to fill with water to the fifth water level, and simultaneously performs a balancing operation at the third water flow intensity (i.e., a drive motor start-stop ratio of 1.2 / 0.8) for 60 seconds, thereby rinsing and shaking the clothes in the washing tub. The third preset water flow intensity can also be any other drive motor start-stop ratio such as 1.2 / 0.9 or 1.2 / 0.7, as long as it is greater than the fourth water flow intensity; the third balancing time can be any other time such as 50 seconds or 70 seconds.

[0084] Furthermore, the third flow intensity includes forward flow intensity and reverse flow intensity, wherein the first rotation time of the forward flow intensity and the second rotation time of the reverse flow intensity are different from each other. For example, the rotation-to-stop ratio of the forward flow intensity is 1.2 / 0.8, and the rotation-to-stop ratio of the reverse flow intensity is 1.1 / 0.8; or, the rotation-to-stop ratio of the forward flow intensity is 1.2 / 0.8, and the rotation-to-stop ratio of the reverse flow intensity is 1.1 / 0.7, etc.

[0085] Based on this, the pulsator washing machine operates alternately with forward and reverse water flow intensities, so that during the process of filling water to the fifth water level, the tangled clothes are washed away and shaken evenly by the water flow.

[0086] Alternatively, in an alternative implementation, after the pulsator washing machine is filled with water to the rinsing level, the pulsator washing machine may perform a balancing operation according to a second water flow intensity.

[0087] In step S445, after the pulsator washing machine is filled with water to the rinsing water level, it is set to a fourth water flow intensity, i.e., a drive motor start-stop ratio of 1.1 / 0.8, and then balanced for 30 seconds to fully rinse and shake the clothes in the washing tub. The fourth preset water flow intensity can also be any other drive motor start-stop ratio, such as 1.1 / 0.9 or 1.1 / 0.7, as long as it is less than the third water flow intensity and greater than the second water flow intensity; the fourth balancing time can be any other time, such as 25 seconds or 45 seconds.

[0088] During the above process, the balancing operation is performed at different stages according to different water flow intensities, which can more effectively disperse and shake the tangled clothes, avoid the drum collision phenomenon that occurs when the pulsator washing machine performs the balancing operation and then performs the spin-drying operation again, thereby improving the user experience.

[0089] It should be noted that in the above process, steps S421 and S422 are not sequential but parallel, and are only related to the judgment result of the clothing type category. The corresponding steps can be executed according to different judgment results.

[0090] See again Figure 2 In step S400, the step of "causing the pulsator washing machine to perform different balancing operations according to the judgment result" further includes:

[0091] S414. If the initial weight is less than or equal to the preset weight, the pulsator washing machine shall perform the third balancing operation.

[0092] In step S414, if the initial weight is less than the preset weight, for example, the preset weight is 3kg and the initial weight of the clothes is 2kg, it means that the weight of the clothes being washed is light or the number of clothes is small. It is only possible that the drum collision is caused by eccentricity. Then, the pulsator washing machine performs a third balancing operation for the drum collision caused by this reason. For example, the pulsator washing machine runs in both forward and reverse directions alternately, thereby eliminating the eccentricity of the pulsator washing machine and further improving the user experience.

[0093] It should be noted that the preset weight and initial weight listed above are merely illustrative and not restrictive. Those skilled in the art can flexibly adjust and set the preset weight according to usage requirements and determine the initial weight based on actual test results in practical applications.

[0094] It should also be noted that in the above process, steps S411 and S414 are not sequential but parallel, and are only related to the judgment result of whether the initial weight of the clothing is greater than the preset weight. The corresponding steps can be executed according to different judgment results.

[0095] The following reference Figure 6 This paper describes one possible control flow of the present invention. Figure 6 This is a logic diagram of the imbalance correction method of the present invention.

[0096] like Figure 6 As shown, a possible complete process of the imbalance correction method of the present invention is as follows:

[0097] S501, Start the pulsator washing machine;

[0098] S502. During the spin-drying process of the pulsator washing machine, determine whether the pulsator washing machine is experiencing a drum collision; if so, proceed to step S503; if not, end the program directly.

[0099] S503. Obtain the initial weight m1 of the clothes in the washing tub of the pulsator washing machine;
