[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative work fall within the scope of protection of the present application.

[0049] For a drum washing machine, its washing method is designed by imitating the principle of a club hitting clothes. A stainless steel inner drum, a mechanical program controller, a shell protected by phosphating, electrophoresis and spraying, and a number of heavy cement blocks for repeated movement to balance the huge centrifugal force generated when the drum rotates, together with washing powder and water, make the clothes clean. That is to say, the inner drum of the drum washing machine is in a horizontal position, the opening of the inner drum faces the horizontal direction, the inner drum can rotate around the horizontal axis, and the lifting ribs in the inner drum drive the clothes to overturn, so as to uniformly wash or dry the clothes.

[0050] During the dehydration process of the drum washing machine, if the clothes are eccentric, that is, the load clothes are concentrated in a certain area of the inner drum of the washing machine, the probability of the inner drum dehydrating at high speed will be affected, and then the dehydration efficiency is affected, or when the dehydration is completed, the moisture content of the clothes is uneven, which leads to a decrease in user experience.

[0051] In the related art, when the clothes are eccentric in the inner drum, the rotation direction and speed of the inner drum are usually adjusted, and then the speed of the inner drum is tried to reach the highest speed. However, when there are many clothes and the clothes are entangled, the ability to uniformly distribute the clothes on the inner drum wall by the above adjustment is limited, and after multiple attempts, the speed of the inner drum still cannot reach the highest speed, which affects the dehydration efficiency.

[0052] In order to reduce the eccentricity of the clothes during the dehydration process, to improve the probability of the inner drum reaching the highest speed during the dehydration process, and to improve the dehydration efficiency, an embodiment of the present application provides a drum washing machine and a control method thereof, which will be described below with reference to the drawings.

[0053] With the increasing demand of users for washing machine functions, the structure of the washing machine has also been greatly improved. For example, in the embodiments of the present application, the drum washing machine includes an inner drum and a base, the inner drum is used to carry clothes, the inner drum has a front end close to the door body of the drum washing machine and a rear end opposite to the front end, and the rear end of the inner drum is rotatably connected with the base to drive the front end of the inner drum to flip towards the direction away from or close to the base. It should be noted that the rotatable connection of the rear end of the inner drum with the base is not a direct connection between the rear end of the inner drum and the base, for example, the box body of the drum washing machine can be rotatably connected with the base, and the inner drum is arranged in the box body and can be flipped according to the flipping of the box body. The base can lift the inner drum on one hand, and can provide support for the inner drum when the inner drum flips on the other hand. In order to improve the stability of the rotation of the inner drum, a support rod can also be provided, which supports the box body and the inner drum when the box body and the inner drum flip, so as to improve the stability of the operation of the inner drum.

[0054] Please refer to Figure 1 , Figure 1 The first flowchart of the control method of the drum washing machine provided in the embodiments of the present application is shown. The embodiments of the present application provide a control method of a drum washing machine, which comprises:

[0055] 101. In the dehydration stage, the first eccentricity value of the clothes in the inner drum is obtained.

[0056] In the dehydration stage, the clothes in the inner drum are eccentric, that is, the clothes are concentrated in a certain area of the inner drum, which will cause the inner drum to be unable to increase the rotation speed. Because the rotation of the inner drum in this stage will cause the inner drum to hit the outer drum in the box body due to eccentricity, a part of energy will be lost when hitting the outer drum, causing the inner drum to be unable to increase the rotation speed. The inner drum operates at a high speed to remove the water in the clothes through centrifugal force, thereby dehydrating the clothes. When the clothes are eccentric, the inner drum can only dehydrate the clothes at a low speed, which will affect the dehydration efficiency and cause the user experience to decrease.

[0057] Therefore, in the dehydration stage, the eccentricity value of the clothes in the inner drum needs to be concerned to adjust when the clothes are eccentric, thereby reducing the eccentricity of the clothes, improving the probability of high-speed dehydration, and further improving the dehydration rate.

[0058] In the dehydration stage, the first eccentricity value of the clothes in the inner drum is obtained. The obtaining method can be through the setting of an eccentricity detection device below the inner drum. The eccentricity detection device can include a plurality of detection parts arranged at intervals, which are distributed along the front end to the rear end of the inner drum to correspond to the detection of the weight at different positions of the inner drum. By comparing the plurality of weight values of the inner drum detected by the plurality of detection parts, the first eccentricity value of the clothes in the inner drum is obtained.

[0059] For example, the first eccentricity value can also be obtained by image method, by collecting the image of the clothes in the inner drum, calculating the proportion of the clothes in the area of the inner drum according to the image, and thus obtaining the first eccentricity value.

[0060] For example, the first eccentricity value can also be determined by detecting the distance of the inner drum offset in the direction of gravity, such as when it is detected that the front end of the inner drum is offset in the direction of gravity relative to the rear end by an amount greater than a set offset amount, the first eccentricity value is selected from a pre-stored offset amount and eccentricity value comparison table.

[0061] Of course, the way to obtain the eccentricity value is not limited to the above-mentioned way, the above-mentioned is only an example and should not be understood as a limitation on the way to obtain the eccentricity value.

[0062] 102、When the first eccentricity value is greater than the first eccentricity threshold value, the front end of the inner drum is controlled to flip in the direction away from the base, and the inner drum is controlled to rotate to shake the clothes.

[0063] When the first eccentricity value exceeds the first eccentricity threshold value, it indicates that the eccentricity of the clothes in the inner drum is more serious at this time, and the clothes cannot be shaken by the conventional control of the inner drum rotating forward and reversing alternately. In this case, the clothes can be shaken by controlling the inner drum to flip.

[0064] The first eccentricity threshold value can be obtained by experiment, such as setting a plurality of eccentricity values corresponding to a plurality of eccentricity conditions, and taking the average or weighted average of the plurality of eccentricity values as the first eccentricity threshold value.

[0065] The front end of the inner drum can be controlled to flip in the direction away from the base by driving the box to rotate by the motor, thereby driving the inner drum to flip, thereby improving the intelligence of the drum washing machine, i.e. automatically flipping the eccentricity adjustment after detecting the eccentricity value. Of course, the front end of the inner drum can also be controlled to flip in the direction away from the base by manual method, i.e. using external force to flip the box to drive the inner drum to flip, the user can control the box to flip at any angle, improving the flexibility of control and the user experience. When flipping the box and the inner drum, a buckle-like form can be provided to remind the user of the flipping angle level, facilitating the user's reference.

[0066] After the inner drum is flipped to the set angle, the inner drum is controlled to rotate to shake the clothes. It can be understood that for the eccentric clothes, the inner drum is flipped to move the clothes eccentric to the front end of the inner drum backward, reducing the eccentricity in the front-rear direction of the inner drum; on this basis, the inner drum is controlled to rotate, such as alternating forward and reverse rotation, to shake the clothes, thereby reducing the eccentricity of the clothes on the circumferential wall of the inner drum.

[0067] 103. Control the inner drum to return to center and obtain the second eccentricity value of the clothes in the inner drum after shaking.

[0068] After flipping and rotating the inner cylinder to shake it out, the inner cylinder is controlled to return to its original position, that is, to restore the initial state in which the front and rear ends of the inner cylinder are flush.

[0069] Obtain the second eccentricity value of the clothes inside the inner drum after shaking. This verifies whether the shaking and rotation of the inner drum is effective in improving the eccentricity. If the improvement is minimal, the clothes can be shaken again by flipping and rotating the drum again, or by adjusting the angle of the flipping to shake them again, in order to reduce the eccentricity value of the clothes.

[0070] The second eccentricity value can be obtained in the same way as the first eccentricity value.

[0071] For example, an eccentricity detection device can be installed below the inner drum. This device can include multiple detection sections spaced apart and distributed along the front to rear of the inner drum to detect the weight at different locations within the drum. By comparing the multiple weight values ​​of the inner drum detected by these multiple detection sections, a second eccentricity value can be obtained for the clothes inside the drum after shaking.

[0072] For example, the first eccentricity value can also be obtained through image method. By acquiring an image of the clothes inside the inner drum, the proportion of the clothes to the area of ​​the inner drum can be calculated based on the image, thereby obtaining the second eccentricity value after shaking.

[0073] For example, the second eccentricity value can also be determined by detecting the distance the inner cylinder is offset in the direction of gravity. For instance, when it is detected that the offset of the front end of the inner cylinder relative to the rear end in the direction of gravity is greater than the set offset, the second eccentricity value is selected from the pre-stored offset and eccentricity value lookup table.

[0074] There are other ways to obtain the second eccentricity value, which will not be listed here.

[0075] 104. When the second eccentricity value is less than or equal to the second eccentricity threshold, the inner drum is controlled to rotate at the first speed to dehydrate the clothes inside the inner drum; the second eccentricity threshold is less than or equal to the first eccentricity threshold.

[0076] When the second eccentricity value is less than or equal to the second eccentricity threshold, it indicates that the eccentricity situation inside the inner cylinder has been greatly improved. In this case, high-speed dehydration can be performed on the inner cylinder to improve the dehydration efficiency.

[0077] It is understandable that since the first eccentricity threshold corresponds to the eccentricity value when the clothes are not shaken out, and the second eccentricity threshold corresponds to the eccentricity value when high-speed dehydration can be performed, the two are in different states, so the parameter values ​​can be the same or different.

[0078] For example, the second eccentricity threshold can be smaller than the first eccentricity threshold. That is, the eccentricity value when the shaking is completed and the vehicle is about to enter the high-speed zone should be smaller than the eccentricity value when the shaking is not performed, so as to distinguish between them and improve the accuracy of control.

[0079] For example, the second eccentricity threshold can be the same as the first eccentricity threshold, thus unifying the eccentricity value for dehydration at high speed. That is, high speed can only be achieved when the eccentricity value is less than the second eccentricity threshold, making the control logic simple.

[0080] Specifically, when the second eccentricity value is less than or equal to the second eccentricity threshold, the inner drum is controlled to rotate at a first speed to dehydrate the clothes inside. The first speed can be the highest speed, such as 1400 rpm; or it can be the second highest speed, such as 1200 rpm. For example, when the second eccentricity value is less than or equal to the second eccentricity threshold, meaning the eccentricity value is within a reasonable range, the highest speed can be tried first for dehydration; if dehydration at the highest speed fails, the second highest speed can then be selected. Alternatively, if the adjusted second eccentricity value is still greater than the second eccentricity threshold, the inner drum can be controlled to dehydrate at the second highest speed.

[0081] After adjusting the shaking and dispersing mechanism, the probability of the inner drum operating at high speed can be increased, rather than at low speeds such as 800 rpm for dehydration, thereby improving dehydration efficiency.

[0082] In the control method of the drum washing machine provided in this application embodiment, during the spin-drying process, when the first eccentricity value of the clothes in the inner drum exceeds the first eccentricity threshold, the front end of the inner drum is controlled to flip away from the base, and the inner drum is controlled to rotate to shake the clothes in the inner drum, thereby reducing the eccentricity of the clothes. This can increase the probability of the inner drum reaching high speed during spin-drying, rather than being unable to reach high speed due to eccentricity and thus performing low-speed spin-drying, thereby improving spin-drying efficiency and improving the user experience.

[0083] Please see Figure 2 As shown, Figure 2 This is a second flowchart illustrating the control method for a drum washing machine provided in an embodiment of this application. An embodiment of this application also provides a control method for a drum washing machine, including:

[0084] 201. During the dehydration stage, obtain the first eccentricity value of the clothes inside the inner drum.

[0085] In the dehydration stage, if the laundry in the inner drum is eccentric, i.e., the laundry is concentrated in a certain area of the inner drum, the inner drum cannot increase the rotation speed. In this stage, the rotation of the inner drum due to eccentricity can cause the inner drum to hit the outer drum in the cabinet, and a part of energy is lost when hitting the outer drum, which causes the inner drum to be unable to increase the rotation speed. The inner drum rotates at a high speed to remove water in the laundry by centrifugal force, thereby dehydrating the laundry. When eccentric, the inner drum can only dehydrate the laundry at a low speed, which affects the dehydration efficiency and causes the user experience to decrease.

[0086] Therefore, in the dehydration stage, the eccentricity value of the laundry in the inner drum needs to be concerned to adjust when the laundry is eccentric, thereby reducing the eccentricity of the laundry, increasing the probability of dehydration at high speed, and further improving the dehydration rate.

[0087] In the dehydration stage, a first eccentricity value of the laundry in the inner drum is obtained. The obtaining method can be to arrange eccentricity detection devices below the inner drum. The eccentricity detection devices can include a plurality of detection parts arranged at intervals. The plurality of detection parts are distributed along the front end to the rear end of the inner drum to correspond to the weight of different positions of the inner drum. By comparing the plurality of weight values of the inner drum detected by the plurality of detection parts, the first eccentricity value of the laundry in the inner drum is obtained.

[0088] For example, the first eccentricity value can also be obtained by image method. The image of the laundry in the inner drum is collected, the proportion of the laundry to the area of the inner drum is calculated according to the image, and the first eccentricity value is obtained.

[0089] For example, the first eccentricity value can also be determined by detecting the distance of the inner drum offset in the direction of gravity. For example, when it is detected that the front end of the inner drum is offset from the rear end in the direction of gravity by an amount greater than a set offset amount, the first eccentricity value is selected from a pre-stored offset amount and eccentricity value comparison table.

[0090] Of course, the method of obtaining the eccentricity value is not limited to the above method. The above is only an example and should not be understood as a limitation on the method of obtaining the eccentricity value.

[0091] 202. According to the first eccentricity value, the turning angle and / or the number of turns of the front end of the inner drum towards the direction away from the base are determined, the turning angle is positively correlated with the first eccentricity value, and the number of turns is positively correlated with the first eccentricity value; and the inner drum is controlled to rotate at a second rotation speed to shake the laundry, the second rotation speed is inversely correlated with the first eccentricity value.

[0092] In the embodiments of the present application, the turning angle and / or the number of turns of the front end of the inner drum towards the direction away from the base can also be determined according to the first eccentricity value, i.e., for different first eccentricity values, the turning angle and / or the number of turns of the inner drum can be controlled.

[0093] For example, the first eccentricity value can be used to determine the turning angle of the inner drum, and the turning angle is positively correlated with the first eccentricity value, that is, the greater the first eccentricity value, the more serious the degree of eccentricity of the clothes at this time, and therefore the turning angle of the inner drum can be increased to increase the probability of the clothes moving from the front end to the rear end of the inner drum, thereby increasing the probability of the clothes being shaken out.

[0094] For example, the first eccentricity value can be used to determine the number of turns of the inner drum, and the number of turns is positively correlated with the first eccentricity value, that is, the greater the first eccentricity value, the more serious the degree of eccentricity of the clothes at this time, and therefore the number of turns of the inner drum can be increased to gradually shake out, thereby increasing the probability of the clothes being shaken out.

[0095] For example, the first eccentricity value can be used to determine the turning angle of the inner drum, and the turning angle is positively correlated with the first eccentricity value, that is, the greater the first eccentricity value, the more serious the degree of eccentricity of the clothes at this time, and therefore the turning angle of the inner drum can be increased to increase the probability of the clothes moving from the front end to the rear end of the inner drum, thereby increasing the probability of the clothes being shaken out.

[0096] After the inner drum is turned to the set angle, the inner drum is controlled to rotate to shake out the clothes. It can be understood that for the eccentric clothes, the inner drum is turned to move the clothes eccentric to the front end of the inner drum backward, reducing the eccentricity in the front-rear direction of the inner drum; on this basis, the inner drum is controlled to rotate, for example, the forward rotation and the reverse rotation are alternated to shake out the clothes, thereby reducing the eccentricity of the clothes on the circumferential wall of the inner drum.

[0097] The second speed of the inner drum during the turning can also be determined according to the first eccentricity value, and the second speed is inversely correlated with the first eccentricity value. That is, the greater the first eccentricity value, the smaller the second speed of the inner drum during the turning, so as to shake out the clothes by slow shaking.

[0098] In addition, the alternating frequency of the forward rotation and the reverse rotation of the inner drum can also be determined according to the first eccentricity value, for example, the alternating frequency of the forward rotation and the reverse rotation of the inner drum can be positively correlated with the first eccentricity value, that is, the greater the first eccentricity value, the greater the alternating frequency of the forward rotation and the reverse rotation of the inner drum, so as to shake out the clothes by high-frequency alternating of the forward rotation and the reverse rotation.

[0099] 203, control the inner drum to return to normal.

[0100] 204, control the inner drum to rotate in a preset manner to adjust the eccentricity of the clothes in the inner drum.

[0101] 205, obtain a second eccentricity value after the eccentricity adjustment of the clothes in the inner drum.

[0102] Regarding steps 203 to 205:

[0103] After the inner drum is flipped and rotated for shaking, the inner drum is controlled to be returned to the original state, that is, the front end of the inner drum is leveled with the rear end.

[0104] After the inner drum is returned, if the second eccentricity value is directly detected, at this time, a small part of the clothes will be gathered due to the return of the inner drum, which will result in a larger second eccentricity value. In order to reduce the occurrence of this situation, after the inner drum is returned, the eccentricity adjustment of the inner drum can be performed before the second eccentricity value is obtained, so as to reduce the eccentricity of the inner drum.

[0105] For example, the inner drum can be controlled to rotate in a preset manner to adjust the eccentricity of the clothes in the inner drum. The preset manner can be that the inner drum is alternately rotated in forward and reverse directions at a set frequency and at a set rotating speed, and the clothes are shaken by the alternately rotating in forward and reverse directions. It can be understood that the clothes wound can be at least partially disentangled by flipping the inner drum for shaking adjustment, and the clothes gathered during the flipping can be shaken after the inner drum is returned, so that the two shaking or eccentricity adjustments can reduce the eccentricity of the clothes and improve the probability of high-speed dehydration, thereby improving the dehydration efficiency.

[0106] The second eccentricity value of the clothes in the inner drum after the eccentricity adjustment is obtained, that is, it is verified whether the flipping and rotating of the inner drum for shaking improves the eccentricity. If the improvement is small, the clothes can be shaken again by flipping and rotating again or by adjusting the angle of flipping to reduce the eccentricity value of the clothes.

[0107] The way of obtaining the second eccentricity value can be the same as the way of obtaining the first eccentricity value.

[0108] For example, an eccentricity detection device can be arranged below the inner drum, and the eccentricity detection device can include a plurality of detection portions arranged at intervals, which are distributed along the front end to the rear end of the inner drum to correspond to the detection of the weight at different positions of the inner drum. The second eccentricity value of the clothes in the inner drum after shaking is obtained by comparing the plurality of weight values of the inner drum detected by the plurality of detection portions.

[0109] For another example, the first eccentricity value can also be obtained by image method, that is, by collecting the image of the clothes in the inner drum, calculating the proportion of the clothes in the area of the inner drum according to the image, and thus obtaining the second eccentricity value after shaking.

[0110] For another example, the second eccentricity value can also be determined by detecting the distance of the inner drum offset in the direction of gravity, for example, when it is detected that the front end of the inner drum is offset from the rear end in the direction of gravity by an amount greater than a set offset amount, the second eccentricity value is selected from a pre-stored offset amount and eccentricity value comparison table.

[0111] There are other ways to obtain the second eccentricity value, which will not be listed here.

[0112] 206、When the second eccentricity value is less than or equal to the second eccentricity threshold, the inner drum is controlled to rotate at a first rotational speed to perform dehydration on the laundry in the inner drum; the second eccentricity threshold is less than or equal to the first eccentricity threshold.

[0113] When the second eccentricity value is less than or equal to the second eccentricity threshold, it indicates that the eccentricity in the inner drum has been greatly improved at this time, and in this case, the high-speed dehydration operation on the inner drum can be performed to improve the dehydration efficiency.

[0114] It can be understood that since the first eccentricity threshold corresponds to the eccentricity value when the laundry is not shaken, and the second eccentricity threshold corresponds to the eccentricity value that can be dehydrated at high speed, the two states are different, and the size of the parameter can be the same or different.

[0115] For example, the second eccentricity threshold can be less than the first eccentricity threshold, that is, the eccentricity value when the high speed is performed after shaking is smaller than the eccentricity value when the shaking is not performed, so as to distinguish and improve the accuracy of control.

[0116] For example, the second eccentricity threshold can be the same as the first eccentricity threshold, so as to unify the eccentricity value for high-speed dehydration, that is, only when the eccentricity value is less than the second eccentricity threshold, the high speed can be performed, and the control logic is simple.

[0117] When the second eccentricity value is less than or equal to the second eccentricity threshold, the inner drum is controlled to rotate at a first rotational speed to perform dehydration on the laundry in the inner drum. The first rotational speed can be the highest rotational speed, such as 1400 rpm; the first rotational speed can also be the second highest rotational speed, such as 1200 rpm. For example, when the second eccentricity value is less than or equal to the second eccentricity threshold, that is, the eccentricity value is within a reasonable range, the highest rotational speed can be tried first to rotate and dehydrate; if the highest rotational speed is not successful, the second highest rotational speed is selected to dehydrate. For example, when the adjusted second eccentricity value is still greater than the second eccentricity threshold, the inner drum can be controlled to dehydrate at the second highest rotational speed.

[0118] After the shaking adjustment, the probability of high-speed rotation of the inner drum can be improved, instead of low-speed dehydration such as 800 rpm, thereby improving the dehydration efficiency.

[0119] The control method of the drum washing machine provided in the embodiments of the present application can be used to control the front end of the inner drum to turn in a direction away from the base when the first eccentricity value of the clothes in the inner drum exceeds the first eccentricity threshold value during the dehydration process of the washing machine, and the inner drum is controlled to rotate to shake the clothes in the inner drum, so as to reduce the eccentricity of the clothes, and thus the probability of high-speed rotation of the inner drum during dehydration can be increased, and the dehydration efficiency can be improved, and thus the user experience can be improved. Moreover, the inner drum turning angle and / or the number of turns can be determined according to the eccentricity value, so that the eccentricity adjustment is more accurate, and the efficiency of the eccentricity adjustment can be improved.

[0120] Referring to Figure 3 as shown, Figure 3 The third flowchart of the control method of the drum washing machine provided in the embodiments of the present application is shown. The embodiments of the present application also provide a control method of a drum washing machine, comprising:

[0121] 301. Obtain the first weight of the clothes in the inner drum.

[0122] For different weights of the clothes in the inner drum, the adjustment methods are also different.

[0123] For example, at the beginning of the dehydration stage, the first weight of the clothes in the inner drum is obtained, and the obtaining method can be obtained by weighing.

[0124] It can be understood that the dehydration process of the clothes is performed after the washing process, and different washing methods can be adopted for different clothes materials before washing the clothes. After the clothes material is determined, only the first weight of the clothes needs to be obtained during the dehydration process, and the subsequent shaking adjustment method can be used as a reference.

[0125] 302. Determine the load type in the inner drum according to the first weight, and the load type includes a first load and a second load, and the weight of the clothes of the first load is greater than the weight of the clothes of the second load.

[0126] The load type in the inner drum can be determined according to the first weight, that is, the clothes are divided into a large load such as the first load with a larger weight and a small load such as the second load with a smaller weight, and different methods can be adopted for the shaking of the large load and the small load.

[0127] For example, the first weight can be compared with the weight threshold value, the first weight greater than or equal to the weight threshold value is determined as the large load, that is, the first load, and the first weight less than the weight threshold value is determined as the small load, that is, the second load.

[0128] 303. When the load type inside the inner drum is the first load and the first eccentricity value is greater than the first eccentricity value, control the front end of the inner drum to flip away from the base and control the inner drum to rotate in order to shake the clothes.

[0129] The weight of clothing corresponds to different loads for large and small loads. If the same shaking or eccentric adjustment method is used for both large and small loads, such as using the conventional method of alternating forward and reverse rotation of the inner drum, it is easy to cause poor shaking under large loads. On the other hand, if both are adjusted by flipping, it is easy to cause excessive shaking under small loads, wasting energy. Therefore, in order to improve the accuracy of clothing shaking, different shaking methods are used for large and small loads.

[0130] When the load type inside the inner drum is the first load, i.e., a large load, and the first eccentricity value is greater than the first eccentricity threshold, the front end of the inner drum is controlled to flip away from the base, and the inner drum is controlled to rotate to shake and disperse the clothes.

[0131] The inner drum can be rotated with its front end pointing away from the base. This is achieved by a motor-driven rotation of the washing machine, which in turn rotates the inner drum. This enhances the washing machine's intelligence, allowing for automatic adjustment based on eccentricity detected. Alternatively, the inner drum can also be rotated manually, using external force to flip the washing machine and rotate the inner drum. Users can control the machine to rotate at any angle, improving control flexibility and user experience. A latch-like mechanism could be incorporated to indicate the appropriate rotation angle for easy reference.

[0132] After the inner drum is flipped to a set angle, it is controlled to rotate to shake out the clothes. It can be understood that for clothes with a heavy load and eccentricity, flipping the inner drum can move the clothes that are eccentric to the front of the inner drum backward, reducing the eccentricity in the front-to-back direction of the inner drum; on this basis, controlling the rotation of the inner drum, such as alternating between clockwise and counterclockwise rotation, can shake out the clothes, thereby reducing the eccentricity of the clothes on the circumference of the inner drum.

[0133] For lightly loaded (secondary load) garments, the inner drum can be rotated in a preset manner to adjust the eccentricity of the garments inside. When the eccentricity of the garments inside the drum is less than the eccentricity threshold, the inner drum is controlled to rotate at a first speed, which can be either the highest or second-highest speed, to dehydrate the garments. The preset mode can be alternating forward and reverse rotation at a set frequency, along with a set inner drum speed. The alternation of forward and reverse rotation disperses the garments.

[0134] The control method of the drum washing machine provided in the embodiments of the present application can improve the accuracy of eccentric adjustment by using different eccentric adjustment modes for large loads and small loads, thereby improving the probability of high-speed dehydration and dehydration efficiency.

[0135] Please refer to Figure 4 as shown, Figure 4 The fourth flowchart of the control method of the drum washing machine provided in the embodiments of the present application. The embodiments of the present application also provide a control method of a drum washing machine, comprising:

[0136] 401, obtain the first weight of the clothes in the inner drum.

[0137] For different weights of the clothes in the inner drum, the adjustment modes are also different.

[0138] For example, at the beginning of the dehydration stage, the first weight of the clothes in the inner drum is obtained, and the obtaining method can be obtained by weighing.

[0139] It can be understood that the clothes dehydration process is performed after the washing process, and different washing methods can be adopted for different clothes materials before washing the clothes. After determining the clothes material, only the first weight of the clothes needs to be obtained in the dehydration process, that is, the subsequent shaking adjustment mode can be used as a reference.

[0140] 402, determine the load type in the inner drum according to the first weight, the load type comprising a first load and a second load, the weight of the clothes of the first load being greater than the weight of the clothes of the second load.

[0141] The load type in the inner drum can be determined according to the first weight, that is, the clothes are divided into a large load such as the first load with a large weight and a small load such as the second load with a small weight, and different shaking modes can be adopted for the large load and the small load.

[0142] For example, the first weight can be compared with the weight threshold, and the first weight greater than or equal to the weight threshold is determined as the first load, and the first weight less than the weight threshold is determined as the second load.

[0143] 403, obtain the water content of the clothes in the inner drum.

[0144] It can be understood that when the clothes have a low water content, the eccentricity in the inner drum is more easily adjusted. When the water content of the clothes is low, that is, the weight of the clothes is reduced, the bulkiness of the clothes is improved, and the clothes are more easily shaken when the inner drum rotates.

[0145] The moisture content of the clothes inside the drum can be determined by the weight of the clothes before and after spin-drying. For example, when entering the spin-drying stage, the first weight m1 of the clothes inside the drum can be obtained. Then, a low spin speed, such as 80 rpm, can be used to spin-dry the clothes to remove at least some of the water. The second weight m2 of the clothes inside the drum after spin-drying can then be obtained. The moisture content L of the clothes inside the drum can be determined based on the first weight m1 and the second weight m2. For example, L = (m1-m2) / m1*100%, which is the percentage of water removed during spin-drying relative to the first weight m1, thus reflecting the moisture content of the clothes.

[0146] 404. When the moisture content of the clothes is less than or equal to the moisture content threshold, the inner drum is controlled to rotate in a preset manner to adjust the clothes inside the inner drum eccentrically.

[0147] When the moisture content of the clothing is less than or equal to the moisture content threshold, that is, when the moisture content of the clothing meets the set conditions, the inner drum can be controlled to rotate in a preset manner to adjust the clothing inside the drum to an off-center position. The preset manner can be alternating between forward and reverse rotation at a set frequency, or a set inner drum rotation speed. By alternating between forward and reverse rotation, the clothing is shaken and dispersed.

[0148] It is understandable that when clothes have a low moisture content, it is easier to adjust the eccentricity inside the inner drum. Because the moisture content of the clothes is low, the weight of the clothes is reduced, the fluffiness of the clothes is increased, and it is easier to shake the clothes when the inner drum rotates.

[0149] 405. If the load type inside the inner cylinder is the first load, then obtain the adjustment duration or number of adjustments for the eccentric adjustment.

[0150] The subsequent adjustment method for the inner sleeve clothing can be determined based on the type of load inside the inner sleeve.

[0151] If the load type inside the inner drum is a small load, i.e., the second load, then the eccentricity value after eccentricity adjustment is obtained. When the eccentricity value after eccentricity adjustment is less than or equal to the eccentricity threshold, the inner drum is controlled to rotate at the first speed to dehydrate the clothes. The first speed is also the highest speed or the second highest speed.

[0152] If the load type inside the inner cylinder is a large load, i.e., the first load, then the adjustment duration or number of adjustments for the eccentric adjustment is obtained. It is understandable that because the eccentric adjustment duration or number of adjustments for a large load is much greater than for a small load, the degree of ordinary eccentric adjustment is limited for a large load. If eccentric adjustment is performed continuously, it can easily lead to wasted energy. Therefore, in this embodiment of the application, after eccentric adjustment of the first load, it is necessary to obtain the adjustment duration or number of adjustments for the eccentric adjustment.

[0153] The duration can be adjusted using a timer, or the number of adjustments can be counted using a counter.

[0154] 406、When the adjustment duration is greater than the preset duration, or the adjustment times is greater than the preset times, if the adjusted eccentricity value is still greater than the eccentricity threshold value, the front end of the inner drum is controlled to be flipped in a direction away from the base, and the inner drum is controlled to rotate to shake the clothes in the inner drum.

[0155] When the adjustment duration is greater than the preset duration, or the adjustment times is greater than the preset times, if the adjusted eccentricity value is still greater than the eccentricity threshold value, the inner drum is controlled to be flipped and shaken, that is, the front end of the inner drum is controlled to be flipped in a direction away from the base, and the inner drum is controlled to rotate to shake the clothes in the inner drum.

[0156] It can be understood that after the conventional eccentricity adjustment is performed on the large load, if the eccentricity threshold value cannot be met, a different eccentricity adjustment method needs to be used, that is, the large load is shaken through flipping and shaking adjustment.

[0157] The front end of the inner drum is controlled to be flipped in a direction away from the base, which can be achieved by driving the box to rotate through the motor, thereby driving the inner drum to flip, thereby improving the intelligence of the drum washing machine, that is, the flipping eccentricity adjustment is automatically performed after the eccentricity value is detected. Of course, the front end of the inner drum can also be flipped in a direction away from the base through a manual method, that is, the box is flipped using external force to drive the inner drum to flip. The user can control the box to flip at any angle, improving the flexibility of control and the user experience. When the box and the inner drum are flipped, a buckle-like form can be provided to remind the user of the flipping angle level, facilitating the user to refer.

[0158] After the inner drum is flipped to a set angle, the inner drum is controlled to rotate to shake the clothes. It can be understood that for the eccentric clothes, the inner drum is flipped to move the clothes eccentric to the front end of the inner drum backward, reducing the eccentricity in the front and rear directions of the inner drum. On this basis, the inner drum is controlled to rotate, such as alternating forward and reverse rotation, to shake the clothes, thereby reducing the eccentricity of the clothes on the circumferential wall of the inner drum.

[0159] The control method of the drum washing machine provided in the embodiments of the present application can improve the probability of shaking the clothes when the moisture content of the clothes is low, thereby helping to improve the probability of dehydrating at high speed and the dehydration efficiency. During the dehydration process of the washing machine, when the first eccentricity value of the clothes in the inner drum exceeds the first eccentricity threshold value, the front end of the inner drum is controlled to be flipped in a direction away from the base, and the inner drum is controlled to rotate to shake the clothes in the inner drum, thereby reducing the eccentricity of the clothes, and thereby improving the probability of the inner drum rotating at high speed during dehydration, rather than being unable to rotate at high speed due to eccentricity and dehydrating at low speed, which can improve the dehydration efficiency and thereby improve the user experience.

[0160] To facilitate better implementation of the control method of the drum washing machine of the embodiments of the present application, the embodiments of the present application further provide a control device of a drum washing machine. Please refer to Figure 5 , Figure 5 The control device of the drum washing machine provided by the embodiments of the present application is shown in a structural schematic diagram.

[0161] The first acquisition unit 501 is configured to acquire a first eccentricity value of the laundry in the inner drum during the dehydration stage.

[0162] The first control unit 502 is configured to control the front end of the inner drum to flip in a direction away from the base when the first eccentricity value is greater than a first eccentricity threshold, and control the inner drum to rotate to shake the laundry.

[0163] The second acquisition unit 503 is configured to control the inner drum to return to the normal position and acquire a second eccentricity value of the laundry in the inner drum after being shaken.

[0164] The second control unit 504 is configured to control the inner drum to rotate at a first rotating speed to dehydrate the laundry in the inner drum when the second eccentricity value is less than or equal to a second eccentricity threshold, and the second eccentricity threshold is less than or equal to the first eccentricity threshold.

[0165] All the above technical solutions can be combined in any manner to form optional embodiments of the present application, which will not be described one by one here.

[0166] In the control device 500 of the drum washing machine provided by the embodiments of the present application, when the first eccentricity value of the laundry in the inner drum exceeds the first eccentricity threshold during the dehydration process of the washing machine, the front end of the inner drum is controlled to flip in a direction away from the base, and the inner drum is controlled to rotate to shake the laundry in the inner drum, thereby reducing the eccentricity of the laundry, and further improving the probability of high speed of the inner drum during dehydration, instead of low speed dehydration due to the inability to speed up caused by the eccentricity, which can improve the dehydration efficiency and further improve the user experience.

[0167] Correspondingly, the embodiments of the present application further provide a drum washing machine, please refer to Figure 6 as shown, Figure 6A structure diagram of a drum washing machine is provided in the embodiments of the present application.
