[0136] In some embodiments of the present application, refer to Figure 7 , the outer diameter of the outer tub can be a first diameter D1.

[0137] The first parameter value < D1. The first parameter value can be 550 mm or 555 mm or 560 mm. Setting the outer diameter of the outer tub to be greater than the first parameter value makes the outer diameter of the outer tub large enough, so that the outer tub is a large-diameter outer tub, facilitating the setting of a large-diameter drum and meeting the user's need for a large washing cavity.

[0138] D1 < the second parameter value. The second parameter value can be 570 mm or 575 mm or 580 mm. Setting the outer diameter of the outer tub to be less than the second parameter value controls the outer diameter of the outer tub within a certain range, avoiding the outer tub having too large a diameter and causing the cabinet to be too large, and meeting the user's need that the overall size of the washing machine is not too large.

[0141] L1 < the fourth parameter value. The fourth parameter value can be 550 mm, 555 mm, or 560 mm. Set the distance between the first central axis and the second central axis to be less than the fourth parameter value, so that the stroke of the shock absorber will not be too large and the angle of the shock absorber will not be too small, avoiding the strength of the shock absorber and the shock absorption ability of the shock absorber being affected due to too large stroke of the shock absorber.

[0188] In some embodiments of the present application, the first fixing member can be clamped with the adapter vertical plate.

[0189] In some embodiments of the present application, the second fixing member may be clamped with the outer cylinder connecting plate.

[0190] In some embodiments of the present application, reference is made to Figure 11 The outer tube 2 may include an outer tube rear wall 23. The outer tube rear wall 23 may be provided at the rear end of the outer tube 2. An air return port 231 may be formed on the inner wall surface of the outer tube rear wall.

[0191] refer to Figure 12 , an air outlet duct 261 can be formed in the outer cylinder. The air outlet duct 261 can be connected to the outer cylinder cavity through the return air port.

[0192] An air outlet 262 may be formed on the outer wall of the outer cylinder.

[0193] In some embodiments of the present application, the return air inlet may be located at one end of the outlet duct. The outlet air inlet may be located at the other end of the outlet duct. The return air inlet and the outlet air inlet may be located at either end of the outlet duct. The outlet air inlet may be located at the top of the outlet duct.

[0195] In some embodiments of the present application, reference is made to Figure 13 The drum washing machine 100 may include a flushing member 63. The flushing member may be connected to the outer drum and may be located at the air outlet. An overflow air duct 6311 may be formed in the flushing member 63. The overflow air duct may be connected to the air outlet duct through the air outlet.

[0196] In some embodiments of the present application, the drum washing machine 100 may include a drying module.

[0197] refer to Figure 13 The drying module may include an air duct housing 50. The air duct housing 50 may be located outside the outer tub. The air duct housing may be connected to the flushing unit.

[0198] A drying air duct 51 may be formed in the air duct housing. One end of the drying air duct may be communicated with the overflow air duct. The other end of the drying air duct may be communicated with the washing chamber.

[0199] In some embodiments of the present application, one end of the drying air duct 51 may be connected to the air outlet through an overflow air duct, and the other end of the drying air duct may be connected to the washing chamber.

[0200] In some embodiments of the present application, to maximize drying efficiency, the drying duct and air circulation path can be extended. The end of the drying duct 51, distal to the return air outlet, can be inserted into the door seal. Air within the drying duct 51 passes through the air seal and the drum opening and enters the drum. The air outlet is located on the side of the outer drum, at the rear end.

[0201] In some embodiments of the present application, a drying device is provided in the drying air duct, and the drying device is capable of drying the air entering the drying air duct.

[0202] During drying, the air in the drum exchanges heat with the clothes to form humid hot air. The humid hot air enters the outer drum and enters the drying duct through the return air outlet. The humid hot air is dried in the return air duct to form dry air. The dry air flows into the washing drum through the other end of the drying duct to exchange heat with the clothes to dry the clothes.

[0203] In some embodiments of the present application, the drying device may include a heating component.

[0204] In some embodiments of the present application, reference is made to Figure 14-15 , a drying fan 852 can be provided in the drying duct. The drying fan can provide power for the flow of air in the drying duct. The drying fan can be provided in the drying duct.

[0205] The drum washing machine will continue to accumulate lint during the drying process. The lint usually accumulates in the drying duct, on the drying device, on the drying fan, on the return air outlet, etc. After long-term use, the lint will clog the air duct and affect the drying efficiency.

[0206] Generally, a flushing structure fixed on the outer cylinder is added and used to flush the return air outlet or the drying fan. However, it is difficult to flush the drying duct and the drying device in the drying duct. As a result, the existing flushing structure has a single function and cannot solve the problem of hair debris accumulation in other complex locations, deep in the drying duct and on the drying device.

[0207] refer to Figure 16-17 A flushing cavity 6312 may be formed in the flushing member 63. A flushing port may be formed on the flushing cavity. The flushing port may be communicated with the flushing cavity.

[0208] In some embodiments of the present application, reference is made to Figure 16-17The flushing port may include a second flushing port 6321. The second flushing port 6321 may be communicated with the flushing cavity. The second flushing port may face the drying air duct.

[0209] In some embodiments of the present application, the drum washing machine may include a water inlet valve for controlling the inflow and stop of water inflow into the flushing chamber.

[0210] Open the water inlet valve and the second flushing port can spray water. Close the water inlet valve and the second flushing port can stop spraying water.

[0211] The rotation of the drying fan can draw water sprayed from the second flushing port into the drying duct to flush the drying fan and the drying duct. This can flush or throw away lint on the drying duct and the drying device and drying fan inside the drying duct, preventing lint accumulation from affecting the drying air volume and temperature, and thus the drying effect.

[0212] In some embodiments of the present application, reference is made to Figure 16-17 The drying fan can be arranged on the side of the flushing part away from the outer cylinder. The drying fan can be arranged opposite to the flushing part. The second flushing port can face the drying fan.

[0213] In some embodiments of the present application, the drying blower may include a drying fan, the drying blower may include a drying motor, and the drying fan may include an impeller.

[0214] In some embodiments of the present application, a drum washing machine may include a controller.

[0215] In some embodiments of the present application, reference is made to Figure 18 , the controller configuration is:

[0216] After receiving the drying duct flushing signal, the drying fan is controlled to rotate, and the water inlet valve is controlled to open and close alternately. The water inlet valve is opened and closed alternately for at least two cycles. Within one cycle, the water inlet valve is opened for a first preset time and closed for a second preset time.

[0217] By setting a drying fan, a second flushing port and a water inlet valve on the flushing part, the drying fan rotates to form a negative pressure to suck water into the drying duct to clean the drying duct, the components in the drying duct and the drying fan. The drying fan can break up the water so that the water can be cleaned in all directions; after receiving the drying duct flushing signal, the drying fan is controlled to rotate continuously, and the water inlet valve is controlled to open and close periodically, which can ensure that the flushing time can achieve strong cleaning of hair debris, facilitate the flow of hair debris and save water resources.

[0218] In some embodiments of the present application, the first parameter value is less than or equal to the first preset time. The first parameter value may be 11 seconds, 10 seconds, or 9 seconds. This prevents the first preset time from being too short, which may result in a short flushing time and affect the flushing effect.

[0219] The first preset time is less than or equal to the second parameter value. The second parameter value can be 13s, 14s, or 15s. Avoid the first preset time being too long, which will cause the rinsing time to be too long and the overall washing time to be too long.

[0220] The third parameter value is ≤ the second preset time. The third parameter value can be 2s, 1.5s, or 1s. Avoiding a short flushing interval due to the second preset time being too short can prevent hair debris from flowing down with the water flow. Avoiding a short flushing interval that affects the flushing effect and prevents continuous water inflow, thereby saving resources.

[0221] The second preset time is less than or equal to the fourth parameter value. The fourth parameter value can be 3.5s, 4s, or 4.5s. Avoid excessive second preset time, which results in a long flushing interval, and avoid excessive proportion of the flushing interval to the cycle time, thereby affecting the flushing effect.

[0222] In some embodiments of the present application, reference is made to Figure 19 , the controller configuration is:

[0223] After receiving the drying duct flushing signal, the water inlet valve is controlled to open. After the water inlet valve is opened for the third preset time, the drying fan is controlled to rotate. After the drying fan rotates for the fourth preset time, the water inlet valve is closed and the drying fan rotates for the fifth preset time.

[0224] By setting a drying fan, a second flushing port and a water inlet valve on the flushing part, the drying fan rotates to form a negative pressure to suck water into the drying duct to clean the drying duct, the components in the drying duct and the drying fan. The drying fan can break up the water so that the water can be cleaned in all directions; after receiving the drying duct flushing signal, the water inlet valve is controlled to work alone for a third preset time and then the drying fan is turned on again, so that the water flow sprayed within the third preset time can play a role in soaking the hair debris; the water inlet valve and the drying fan are set to work simultaneously for the fourth preset time, which can be used for flushing so that the hair debris can be cleaned; the drying fan is set to work alone for the fifth preset time, so that the drying fan can centrifugally throw out some of the hair debris to further clean the hair debris.

[0225] In some embodiments of the present application, the fifth parameter value is less than or equal to the third preset time. The fifth parameter value may be 9s, 8s, or 7s. This is to prevent the third preset time from being too short, which may result in a short infiltration time and affect the infiltration effect.

[0226] The third preset time is less than or equal to the sixth parameter value. The sixth parameter value can be 11 seconds, 12 seconds, or 13 seconds. This is to avoid the third preset time being too long, which will cause the immersion time to be too long and increase the overall flushing time, and to avoid wasting water.

[0227] In some embodiments of the present application, the seventh parameter value is less than or equal to the fourth preset time. The seventh parameter value can be 9s, 8s, or 7s. This prevents the fourth preset time from being too short, which results in a short flushing time and affects the flushing effect.

[0228] The fourth preset time is less than or equal to the eighth parameter value. The eighth parameter value may be 11 seconds, 12 seconds, or 13 seconds. This is to avoid the fourth preset time being too long, which would cause the flushing time to be too long and increase the overall flushing time, and to avoid wasting water.

[0229] In some embodiments of the present application, the ninth parameter value is less than or equal to the fifth preset time. The ninth parameter value can be 9s, 8s, or 7s. This prevents the fifth preset time from being too short, which results in a short dander removal time and affects the dander removal effect.

[0230] The fifth preset time is less than or equal to the tenth parameter value. The tenth parameter value can be 11 seconds, 12 seconds, or 13 seconds. Avoid setting the fifth preset time too long to cause the lint to be thrown out too long, thereby increasing the overall flushing time.

[0231] In some embodiments of the present application, reference is made to Figure 19 , the controller configuration is:

[0232] After the drying fan rotates for a fifth preset time, the water inlet valve is opened again, and the drying fan rotates and the water inlet valve is opened simultaneously for a sixth preset time.

[0233] Setting the drying fan and the water inlet valve to work simultaneously again can flush out the hair debris thrown out by the drying fan, thereby improving the cleanliness of the accumulated hair debris.

[0234] In some embodiments of the present application, the eleventh parameter value is less than or equal to the sixth preset time. The eleventh parameter value may be 9s, 8s, or 7s. This prevents the sixth preset time from being too short, which may result in a short lint flushing time and affect the lint flushing effect.

[0235] The sixth preset time is less than or equal to the twelfth parameter value. The twelfth parameter value can be 11 seconds, 12 seconds, or 13 seconds. Avoid the sixth preset time being too long, which will cause the lint cleaning time to be too long and increase the overall flushing time.

[0236] In some embodiments of the present application, when processing the hair debris in the drying duct, the speed of the drying fan is high, so that the drying fan can suck the water sprayed from the second flushing port into the drying duct, and can shake off the hair debris on the drying fan, and can also blow off the hair debris attached to the drying duct, making it convenient to clean the hair debris.

[0237] In some embodiments of the present application, the drying duct may be flushed after the washing stage of the drum washing machine and before the rinsing stage.

[0238] In some embodiments of the present application, the drying duct of the drum washing machine can be flushed after the rinsing stage is completed and between the dehydration stages.

[0239] In some embodiments of the present application, the second flushing port 6321 can be provided in the overflow air duct. The second flushing port can connect the flushing cavity and the overflow air duct.

[0240] In some embodiments of the present application, the hot and humid air is dried only through the drying air duct, and the drying effect is poor. Therefore, a condenser can be set on the rear side of the rear wall of the outer cylinder to condense the hot and humid air before or when it enters the drying air duct, so that the hot and humid air is cooled and dehumidified.

[0241] However, the existing condenser is generally arranged at the rear part of the rear wall of the outer cylinder, and the heat exchange efficiency between the condenser and the hot and humid air is low. The condenser has a poor dehumidification effect on the hot and humid air, which makes it difficult to dry the hot and humid air and takes a long time to dry clothes. In addition, during the drying process, there will be more hair debris in the air. During the flow of air, the air can easily bring hair debris into the drying duct, so that the inner surface of the drying duct and the surface of the drying device are attached with hair debris. After a long period of accumulation, it will affect the patency of the drying duct and the heat exchange between the drying device and the air, making the drying time longer. A filter component can be set at the return air inlet, but hair debris will accumulate on the filter component and cause the filter part to be blocked, affecting the return air of the return air inlet and the normal filtration of the filter component.

[0242] refer to Figure 20-21 The drum washing machine may include a condensation tray 52. ​​The condensation tray 52 may be provided in the outer drum 2. The condensation tray may be connected to the outer drum rear wall 23. The condensation tray may be used to exchange heat with the hot and humid air during drying so that the moisture in the hot and humid air condenses.

[0243] refer to Figure 20-21 The condensation tray 52 may include a shielding area 521 . The shielding area 521 may shield the return air outlet 231 .

[0244] The return air vent 231 may be located at the upper portion of the rear wall of the outer tube. The shielding area 521 may be located at a position that matches the return air vent.

[0245] refer to Figure 20-21 A filter portion 5211 may be formed on the shielding area 521. The filter portion 5211 may connect the return air port 231 and the space near the outer cylinder opening of the condensation pan. The filter portion 5211 may be used to filter the air flowing through the filter portion.

[0246] The hot and humid air generated by drying clothes in the washing chamber of the drum enters the outer drum, and the hot and humid air flows from the side of the condensation plate close to the opening of the outer drum to the condensation plate. The hot and humid air exchanges heat with the condensation plate to condense the moisture in the hot and humid air, and the hot and humid air flows to the return air outlet through the filter part. The hot and humid air passing through the return air outlet enters the drying air duct, and the filter part filters the hot and humid air flowing through the filter part.

[0247] In some embodiments of the present application, reference is made to Figure 22-Figure 29 The flushing port may include a first flushing port 6331. The first flushing port 6331 may be connected to the flushing cavity. The first flushing port may face the return air port.

[0248] Open the water inlet valve, water enters the flushing cavity, and water flows out from the first flushing port. Close the water inlet valve, and no water flows out of the first flushing port.

[0249] At least part of the water in the flushing cavity is sprayed out from the first flushing port, and the water sprayed from the first flushing port flushes the return air port and the filter portion.

[0250] A flushing piece is provided with a flushing cavity and a first flushing port, which can flush the return air port and the filter part to prevent hair debris from blocking the filter part and ensure the return air of the return air port and the normal filtering function of the filter part.

[0252] The flushing member 63 may include a flushing tray 633. The connecting member 63 may be arranged on the outside of the flushing tray. The connecting member may be connected to the flushing tray to form a flushing cavity 6312 located therebetween. The connecting member may also be connected to the flushing tray to form an overflow air duct 6311.

[0253] The connecting piece can be sealed and connected to the drying air duct.

[0254] The flushing cavity can be arranged in a circumferential manner and can surround the outer side of the overflow air duct.

[0255] In some embodiments of the present application, reference is made to Figure 22-Figure 29 , the connecting member 632 may include a connecting member partition 6322. The connecting member 632 may include a connecting member enclosure 6323.

[0256] The end of the connector enclosure 6323 away from the outer cylinder can be connected to the connector partition. The connector enclosure can be arranged in a circular manner. The connector enclosure and the connector partition can enclose a connector cavity 6324 located on the side of the connector partition near the outer cylinder. The flushing tray can be located in the connector cavity.

[0318] The filter holes 52111 are arranged vertically in the length direction.

[0319] In some embodiments of the present application, reference is made to Figure 30 The drum washing machine may include a motor 861. The motor 861 may be disposed within the housing. The motor 861 may be connected to the rear end of the outer drum. The motor 861 may drive the drum to rotate.

[0320] In some embodiments of the present application, the drum washing machine may include a first detection device 862 .

[0321] The first detection device 862 can be provided on the outer cylinder. The first detection device can be provided on the top of the outer cylinder. The first detection device can be located on the front side of the outer cylinder. The first detection device can be used to detect the vibration displacement and vibration acceleration of the outer cylinder.

[0322] The first detection device can transmit the vibration value and vibration acceleration to the controller through serial communication.

[0323] The first detection device may be a 3D vibration displacement sensor.

[0324] In some embodiments of the present application, the controller may have an eccentric mass M built into it. i The corresponding first vibration displacement A i , i≥1, and i is a positive integer.

[0325] The mass of the eccentric block inside the drum is M i The vibration displacement detected during the process of the drum speed accelerating to the first speed is the first vibration displacement A i .

[0326] The controller can have an eccentric mass M built into it i The corresponding second vibration displacement B i The mass of the cloth loaded in the drum is M i The vibration displacement detected during the process of the drum speed accelerating to the first speed is the second vibration displacement B i .

[0327] The first rotation speed may be 400 rpm.

[0328] The thirteenth parameter value is less than the first speed. The thirteenth parameter value can be 390 rpm, 380 rpm, or 370 rpm to avoid the difficulty in detecting the first vibration displacement and the second vibration displacement due to a too low speed.

[0329] The first speed is less than the fourteenth parameter value. The fourteenth parameter value can be 410 rpm, 420 rpm, or 430 rpm, to avoid excessive speed affecting the detection accuracy of vibration displacement in the low-speed transient stage, thereby making the correction of vibration displacement in the low-speed transient stage more accurate.

[0330] In some embodiments of the present application, reference is made to Figure 31 , the controller configuration is:

[0331] After receiving the dehydration signal, the controller controls the motor to start, and the motor increases the rotation speed of the drum to the first rotation speed at the first acceleration. During the process of the motor increasing the rotation speed of the drum to the first rotation speed at the first acceleration, the first detection device acquires the vibration displacement of the outer drum and records it as the detected vibration displacement E.

[0332] According to the detected vibration displacement E, the first vibration displacement A i and the second vibration displacement B i obtain the corrected vibration displacement E'. When E ≤ A1, E' = E + (A1 - B1), A i < E ≤ A i+1 when, E' = E + (A i - B i ).

[0333] Judge whether the corrected vibration displacement E' is greater than the maximum limit value of the vibration displacement. When the corrected vibration displacement E' is not greater than the maximum limit value of the vibration displacement, the motor raises the rotation speed of the drum to the rotation speed N; when the corrected vibration displacement E' is greater than the maximum limit value of the vibration displacement, the motor decelerates to 0 and shakes the clothes in the drum.

[0334] The detected vibration displacement during the process of the drum rotation speed increasing to the first rotation speed fluctuates greatly. Therefore, correcting the detected vibration displacement during the process of the drum rotation speed increasing to the first rotation speed can improve the accuracy of the vibration displacement at low-speed transients, can accurately determine whether the drum continues to speed up for dehydration or is shaken again, can improve the success rate of dehydration completion, shorten the dehydration time, and improve the user experience.

[0335] In some embodiments of the present application,

[0336] When E ≤ A1, E' = E + (A1 - B1); when A1 < E ≤ A2, E' = E + (A2 - B2); when A2 < E ≤ A3, E' = E + (A3 - B3);

[0337] When A3 < E ≤ A4, E' = E + (A4 - B4); when A4 < E ≤ A5, E' = E + (A5 - B5); when A5 < E ≤ A6, E' = E + (A6 - B6);...;

[0338] A i < E ≤ A i+1 when, E' = E + (A i - B i ).

[0339] The unit of the eccentric mass is g. M i can be any eccentric mass. M1 = 100g; M2 = 200g; M3 = 300g; M4 = 400g;... M 10 = 1000g.

[0340] Eccentric masses can be divided into four categories: small load, medium load, large load and extra large load.

[0341] Small loads can correspond to M1, M2, M3. Medium loads can correspond to M4, M5, M6, M7, M8. Large loads can correspond to M9, M10, M11, M12, M13, M14, M15, M16, M17, M18. 10 . Extra large load can correspond to M 11 and above.

[0342] The unit of vibration displacement is mm. The eccentric block 864 can be placed inside the drum. The load cloth can be placed inside the drum. The top of the outer drum can be hung on the box via a hanging spring 863.

[0343] In some embodiments of the present application, reference is made to Figure 32 , the controller can have a built-in vibration displacement limit value C j , j≥1, and j is a positive integer. The larger the j value, the greater the vibration displacement limit value C j The larger the value, the greater the vibration displacement limit value C j The one with the largest value can be the maximum limit value of vibration displacement.

[0344] N=n j , the smaller the j value, the j The bigger.

[0345] When E'≤C1, N=n1, C j <E'≤C j+1 When N=n j+1 The target speed N is divided into different values, and the target speed is different when the vibration displacement is different. The larger the vibration displacement, the smaller the target speed N, which can reduce the vibration noise during dehydration and ensure the normal dehydration.

[0346] In some embodiments of the present application, A1-A i The vibration displacement of each segment can be divided into j consecutive segments. Each segment can have at least one first vibration displacement value. The maximum first vibration displacement value of each segment can be the vibration displacement limit value C of the segment. j .

[0347] j can be 3. Vibration displacement limit value C j It can be divided into three gears.

[0348] C1=max(A1~A3); C2=max(A4~A8); C3=max(A9~A 10 ).

[0349] In some embodiments of the present application, reference is made to Figure 33 , the controller configuration is:

[0350] After the motor raises the drum rotation speed to rotation speed N, the vibration acceleration of the drum at rotation speed N is obtained and recorded as the detected vibration acceleration F. When the detected vibration acceleration F is not greater than the maximum limit value of the vibration acceleration, the motor drives the drum to maintain the current rotation speed for a certain period of time and then decelerates to 0. Alternatively, the motor decelerates the drum to a certain speed, and the motor drives the drum to maintain the decelerated rotation speed for a certain period of time and then decelerates to 0. When the detected vibration acceleration F is greater than the maximum limit value of the vibration acceleration, the motor decelerates to 0 and shakes the clothes in the drum. It can determine whether the drum can complete dehydration at the current rotation speed according to the vibration acceleration when the rotation speed is relatively high. When the vibration acceleration is too large, the rotation speed can be reduced or shaken again, which can ensure the continuous progress of high-speed dehydration and reduce the vibration noise of high-speed dehydration.

[0351] In some embodiments of the present application, after the foreign objects in the drum are shaken out, the motor is restarted, and the motor raises the rotation speed of the drum to the first rotation speed with the first acceleration.

[0352] In some embodiments of the present application, the controller may be built-in with a vibration acceleration limit value D k , k≥1, and k is a positive integer. The larger the value of k, the k larger the vibration acceleration limit value D. The largest value among the numerical values of the vibration acceleration limit value D k is the maximum limit value of the vibration acceleration.

[0353] The motor raises the drum to a rotation speed N of n j .

[0354] Under the condition that the detected vibration acceleration F is not greater than the maximum limit value of the vibration acceleration, when F≤D k and K≤j are satisfied, the motor drives the drum to maintain the current rotation speed for a certain period of time and then decelerates to 0. When D k <F and j≤K are satisfied, the motor decelerates the drum to a certain speed, and the motor drives the drum to maintain the decelerated rotation speed for a certain period of time and then decelerates to 0. It can ensure that at different rotation speeds N, it can be determined whether to maintain the current rotation speed or decelerate according to the vibration acceleration, and it can be reasonably determined so as to dehydrate at a relatively high speed as much as possible under the condition that the noise is satisfied, improving the dehydration effect.

[0355] In some embodiments of the present application, the motor raises the drum to a rotation speed N of n j , under the conditions that the detected vibration acceleration F is not greater than the maximum limit value of the vibration acceleration and D k <F and j≤K are satisfied, when D k+o <F≤D k+o+1 is satisfied, the motor decelerates the drum to a certain speed N'=n k+o+1, k ≥ 1, and k is a positive integer, o is a natural number. It is possible to determine which specific rotational speed is appropriate when the drum decelerates, avoiding excessive deceleration that reduces the dehydration effect and avoiding too low deceleration that results in a relatively large noise.

[0356] In some embodiments of the present application, the controller may be internally provided with an eccentric mass M i The corresponding first vibration acceleration G i , i ≥ 1, and i is a positive integer. The vibration acceleration detected when the drum rotational speed is the second rotational speed is the first vibration acceleration G i , and the second rotational speed is greater than the first rotational speed.

[0357] M1 - M 10 The corresponding first vibration acceleration is G1 - G 10 . M i The corresponding first vibration acceleration is G i .

[0358] In some embodiments of the present application, G1 - G i can be divided into k consecutive segments. Each segment may have at least one first vibration acceleration value. The maximum first vibration acceleration value of each segment is the vibration displacement limit value D of this segment k .

[0359] k can be 3. The vibration displacement limit value D k can be divided into three grades. D1 = max(G1~G3); D2 = max(G4~G8); D3 = max(G9~G 10 ).

[0360] The drum rotational speed N can be in 3 grades. N = n1; N = n2; N = n3. n1, n2, n3 decrease in sequence.

[0361] In some embodiments of the present application, A1 - A i The number of segments divided can be equal to the number of segments that G1 - G i is divided into. For the same eccentric mass M i The segments where the corresponding first vibration displacement and first vibration acceleration are located can be equal. This makes the vibration displacement limit value and the vibration acceleration limit value match each other, ensuring that the judgment of vibration displacement and vibration acceleration is under the same standard.

[0362] In some embodiments of the present application, after obtaining the corrected vibration displacement E', when E' ≤ C1, the motor raises the drum rotational speed to n; when C1 < E' ≤ C2, the motor raises the drum rotational speed to n2; when C2 < E' ≤ C3, the motor raises the drum rotational speed to n3; when C3 < E', the motor decelerates to 0 and shakes the clothes inside the drum.

[0363] After the motor raises the drum speed to n1, when F ≤ D1, the motor drives the drum to run at the speed of n1 for the first holding time and then decelerates to 0; when D1 < F ≤ D2, the motor drives the drum to decelerate to the speed of n2 and run for the first holding time and then decelerates to 0; when D2 < F ≤ D3, the motor drives the drum to decelerate to the speed of n3 and run for the first holding time and then decelerates to 0; when D3 < F, the motor decelerates to 0 and shakes the clothes in the drum.

[0364] After the motor raises the drum speed to n2, when F ≤ D2, the motor drives the drum to run at the speed of n2 for the first holding time and then decelerates to 0; when D2 < F ≤ D3, the motor drives the drum to decelerate to the speed of n3 and run for the first holding time and then decelerates to 0; when D3 < F, the motor decelerates to 0 and shakes the clothes in the drum.

[0365] After the motor raises the drum speed to n3, when F ≤ D3, the motor drives the drum to run at the speed of n3 for the first holding time and then decelerates to 0; when D3 < F, the motor decelerates to 0 and shakes the clothes in the drum.

[0366] The first holding time can be 60s.

[0367] The fifteenth parameter < the first holding time. The fifteenth parameter can be 55s or 50s or 45s. Avoiding too short time resulting in poor dehydration effect.

[0368] The first holding time < the sixteenth parameter. The fifteenth parameter can be 65s or 70s or 75s. Avoiding too long time resulting in too long dehydration time, occupying too much time and affecting the user experience.

[0369] In some embodiments of the present application, after the motor drives the drum to run for the first holding time and then decelerates to 0, the dehydration ends.

[0370] In some embodiments of the present application, the level of the load in the drum is determined according to the detected vibration displacement E before obtaining the corrected vibration displacement E'.
