Abstract

The present invention discloses an eccentricity adjustment assembly for a washing machine and a washing machine. The eccentricity adjustment assembly includes: a lifting rib structure, which is fixedly mounted on the inner side of the drum of the washing machine and has a cavity capable of accommodating water; a centrifugal water channel, which is fixedly mounted on the rear flange of the drum and has a water inlet for injecting water into the cavity; and a water inlet structure, which is provided with a nozzle capable of spraying water into the water inlet. By providing the centrifugal water channel for injecting water into the cavity, the weight of the lifting rib structure is increased, the eccentricity of the washing machine during dehydration can be adjusted, and the balancing ability of the washing machine can be increased. During the dehydration process of the washing machine, if eccentricity occurs and the dehydration process cannot be started, water needs to be injected into the cavity. By opening the nozzle, the water injected by the nozzle can enter the water inlet, and then the water in the water inlet is injected into the cavity by the centrifugal force of the rotating drum, thereby increasing the weight of the lifting rib structure and playing the role of eccentricity adjustment.

Description

Technical Field

[0001] The present invention belongs to the technical field of washing machines, and in particular relates to an eccentricity adjustment component of a washing machine and a washing machine having the eccentricity adjustment component. Background Art

[0002] As people's living standards improve, drum washing machines are increasingly entering households. Drum washing machines dehydrate clothes by spinning them out of the drum through centrifugal motion. However, during dehydration, drum washing machines are susceptible to uneven distribution of clothes within the drum, resulting in offsets. This can cause drum collisions, where the drum hits the outer casing. In severe cases, displacement can occur, creating significant noise and shortening the washing machine's service life. As washing machine capacity continues to increase and spin speeds continue to rise, the problem of vibration and displacement during the dehydration process is increasingly becoming a bottleneck in the continued development of washing machine technology.

[0003] Before dehydration, an eccentricity check is performed. If eccentricity is detected, the inner drum is generally rotated to redistribute the clothes inside the drum to eliminate the eccentricity. However, even after load redistribution, there are cases where eccentricity persists, requiring only an alarm and manual intervention. The current approach to tackling eccentricity is simply load redistribution, which results in limited handling capabilities.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Summary of the Invention

[0024] Furthermore, the centrifugal water channel also has a water outlet channel connected to the water outlet of the lifting rib structure, and the water outlet channel is coaxially arranged with the water inlet channel.

[0025] Furthermore, the water outlet is located outside the water inlet.

[0026] Furthermore, a water inlet is provided on the lifting rib structure, and a mounting port is opened on the rear flange. The water inlet extends out of the mounting port and is communicated with the water outlet of the water inlet.

[0064] Example 1

[0065] See also Figure 1-Figure 22 , is an embodiment of a washing machine eccentric adjustment assembly proposed by the present invention, an eccentric adjustment assembly for a washing machine, comprising: a lifting rib structure 10, a centrifugal water channel 30, and a water inlet structure 40. The lifting rib structure 10 is fixedly mounted on the inner side of the drum 20 of the washing machine, and has a cavity 14 capable of accommodating water; the water inlet structure 40 is fixedly mounted on the rear end of the outer drum 50, and the centrifugal water channel 30 is fixedly mounted on the rear flange 21 of the drum 20, and has a water inlet 31 for injecting water into the cavity 14; the water inlet structure 40 is provided with a nozzle 41 capable of spraying water into the water inlet 31. By setting up a centrifugal water channel 30 for injecting water into the cavity 14, the weight of the lifting rib structure 10 is increased, the eccentricity of the washing machine during dehydration can be adjusted, and the balance ability of the washing machine can be increased; in the dehydration process of the washing machine, when eccentricity occurs and the dehydration process cannot be started, water needs to be injected into the cavity 14, and the nozzle 41 is opened. The water flow sprayed by the nozzle 41 can enter the water inlet channel 31, and then the centrifugal force of the rotation of the drum 20 is used to inject the water in the water inlet channel 31 into the cavity 14, so that the weight of the lifting rib structure 10 is increased, which plays a role in eccentricity adjustment.

[0066] See also Figure 2 As shown, the lifting rib structure 10 is located within the drum 20 and needs to rotate with the drum 20. The centrifugal water channel 30 is connected to the lifting rib structure 10. As a method for providing water flow to the centrifugal water channel 30, a retractable pipe can be provided between the nozzle 41 and the water inlet 31 to connect the nozzle 41 and the water inlet 31, thereby delivering pressurized water into the water inlet 31. In this embodiment, the nozzle 41 and the water inlet 31 are spaced apart. Water in the nozzle 41 is sprayed into the water inlet 31. The water in the water inlet 31 flows into the cavity 14 due to the centrifugal force generated by the rotation of the drum 20; that is, water enters the water channel 30 due to centrifugal force during the rotation of the drum 20. Preferably, the centrifugal water channel 30 is an arc-shaped structure coaxially arranged with the rear flange 21.

[0067] In this embodiment, three lifting rib structures 10 are evenly distributed on the drum 20, and three centrifugal water channels 30 are also provided. In other embodiments, one lifting rib structure 10 may also be provided.

[0068] See also Figure 2-Figure 7 、 Figure 9 、 Figure 13 The figure shows the specific structure of the water inlet 31. The water inlet 31 has an arc-shaped water inlet cavity 311. The water inlet cavity 311 is provided with a water inlet port 312 on the side close to the water inlet structure 311. The water inlet port 312 is used for the water flow sprayed by the nozzle 41 to enter the water inlet cavity 311. The nozzle 41 is fixed to the rear end of the outer cylinder 50. When the nozzle 41 is opened, the water flow is sprayed into the water inlet cavity 311 when the water inlet port 312 rotates with the drum 20 through the nozzle 41. It can be arranged that the nozzle 41 and the water inlet port 312 are in a coaxial arc surface, that is, the distance between the nozzle 41 and the axis of the drum 20 is equal to the distance between the water inlet port 312 and the axis of the drum 20. The water inlet port 312 is an arc-shaped strip structure.

[0069] The water inlet cavity 311 is provided with a plurality of water storage baffles 3112, which are used to separate a plurality of water storage chambers 3111 from the water inlet cavity 311. The water storage baffles 3112 extend radially outward along the inner diameter of the water inlet cavity 311. The plurality of water storage chambers 3111 are arranged adjacent to each other in the circumferential direction. The provision of multiple water storage chambers 3111 improves the water storage capacity of the water inlet cavity 311. Water injected into the water storage chambers 3111 is blocked by the water storage baffles 3112, imparting a force that forces the water flow to follow the rotation of the drum 20. The water inlet cavity 311 also includes a centrifugal connection portion 3113 located outside the plurality of water storage chambers 3111. The centrifugal connection portion 3113 is used to transport water within the water inlet cavity 311 to the cavity 14. Water entering the water inlet cavity 311 moves outward under the action of centrifugation and enters the centrifugal connection portion 3113. The water storage partition 3112 is spaced apart from the outer diameter side wall of the water inlet cavity 311 , that is, a continuous centrifugal communication portion 3113 is formed in the water inlet cavity 311 .

[0070] In order to allow the water sprayed into the water inlet channel 312 to enter the lifting rib structure 10 through the water inlet channel cavity 311, a water inlet nozzle 313 is provided at the water inlet channel 312, extending inward and toward the water inlet structure 40. The water inlet nozzle 313 is tilted, which is conducive to guiding the water flow sprayed by the nozzle 41 outward, so that the water flow has a radial outward force. After the water flow enters the water storage chamber 3111, the water storage baffle 3112 gives the water flow a rolling driving force, and under the action of the outward force, the water flow enters the centrifugal connecting part 3113.

[0071] See also Figure 7 and Figure 13As shown, the water inlet nozzle 313 has a first water inlet edge 3131 and a second water inlet edge 3132 extending backward and inward along the inner and outer ends of the water inlet channel opening 312. The axial projection of the second water inlet edge 3132 covers the water inlet channel opening 312, that is, if the water flow ejected by the nozzle 41 is axial, it cannot enter the water inlet nozzle 313. The direction of the water flow ejected by the nozzle 41 is set to be outward and forward, so that the water flow ejected by the nozzle 41 has an outward force; preferably, the direction of the water flow ejected by the nozzle 41 is set to be inclined with the rotation direction of the drum 20 when water is injected into the lifting rib structure 10, so that the ejected water flow has the force in the rotation direction of the drum 20 and the outward centrifugal force, which is conducive to the water flow entering the water inlet channel cavity 311 and flowing into the cavity 14 through the centrifugal connecting portion 3113.

[0072] Multiple radially inwardly extending extension plates 3133 are spaced apart from the second water diversion rim 3132. These extension plates 3133 serve to separate the water inlet openings 312. The radial cross-section of the outer end surface of the first water diversion rim 3131 is arcuate, while the radial cross-section of the inner end surface of the second water diversion rim 3132 is linear. The first and second water diversion rims 3131 are arranged parallel to each other. The water inlet openings 312 are located inside the water inlet cavity 311, that is, they are formed on the multiple water storage chambers 3111.

[0073] The centrifugal water channel 30 also has an outlet 32 connected to the outlet 126 of the lifting rib structure 10. The outlet 32 is used to discharge water from the cavity 14. The outlet 32 is coaxial with the inlet 31 and is located outside the inlet 31. One end of the inlet 31 extends outward to the end of the outlet 31 and is provided with a waterway outlet 314. The lifting rib structure 10 is provided with an inlet 125, which extends out of the mounting opening on the rear flange 21 and connects to the outlet 314 of the inlet 31. One end of the outlet 31 is provided with a waterway inlet 321, adjacent to the waterway outlet 314. The rear flange 21 is provided with a mounting platform that matches the rear end surface of the lifting rib structure 10, with the mounting opening 211 formed on the mounting platform 212.

[0074] The water inlet 31 is composed of a water channel bottom 319 and a water channel cover 318 that are interlocked with each other. The water channel cavity 311 is set on the water channel bottom 319, and the water inlet port 312 and the water nozzle 313 are set on the water channel cover 318.

[0075] See also Figure 15-Figure 22As shown, the structure of the lifting rib structure 10 is explained. The lifting rib structure 10 includes: a base 11, an upper cover 12, and an internal water channel 13. The base 11 is fixed to the drum 20 by screws, and the upper cover 12 is sealed and mounted on the inner side of the base 11. The upper cover 12 is close to the axis oo direction of the drum 2. The internal water channel 13 is arranged in a cavity 14 that can hold water and is surrounded by the base 11 and the upper cover 12. Water can be injected into the cavity 14, and the water flows into the internal water channel 13 after entering the cavity 14; a water inlet 125 connected to the internal water channel 14 is opened on the base 11 or the upper cover 12, and a plurality of partition plate assemblies are arranged in a front-to-back manner in the cavity 13. The plurality of partition plate assemblies are used to partition the cavity 14 into a plurality of interconnected chambers 141, and a plurality of chambers 141 constitute a chamber 14. By providing the lifting rib structure 10 with a cavity 14 capable of accommodating water, the weight of the lifting rib structure 10 can be adjusted by injecting water into the cavity 14, and the eccentricity of the washing machine during dehydration can be adjusted, which is beneficial for improving the washing machine's ability to resist eccentricity. By adjusting the overall weight of multiple lifting rib structures 10, the weight of the drum 20 can be increased, which is beneficial for increasing the washing machine's ability to resist eccentricity. By adjusting the weight of some lifting rib structures 10, the center of gravity of the load can be corrected, and the diagonal eccentricity can be adjusted. In addition, multiple interconnected chambers 141 are provided in the cavity 14. By adjusting the water in the cavity 14 to be mainly distributed in the front chamber or the rear chamber, the center of gravity of the lifting rib structure 10 can be adjusted in the front-to-back direction, achieving adjustment of the front-to-back eccentricity.

[0076] See also Figure 15 As shown, in this embodiment, a water inlet 125 and a water outlet 126 are provided on the upper cover 12. The water inlet 125 and the water outlet 126 are arranged side by side at the rear end of the base 10. The water inlet 125 is connected to the internal water channel 13; water flowing into the water inlet 125 flows into the internal water channel 13. The base 11 and the upper cover 12 are sealed and connected to form a cavity 14.

[0077] In other embodiments, the water inlet 125 or the water outlet 126 may be provided on the base 11 .

[0078] See also Figure 16 As shown, the internal water channel 13 is used to transport the water flow entering from the water inlet 125 to the end of the cavity 14 away from the water inlet 125. In this embodiment, the water inlet 125 and the water outlet 126 are arranged at the rear end of the base 10, and the internal water channel 13 flows the water flow from the back to the front, and flows out of the internal water channel 13 at the front of the cavity 14; a plurality of chambers 141 are adjacently arranged in the front and rear directions in the cavity 14, that is, the water flow first reaches the chamber 141 at the front end of the cavity 14, and the plurality of chambers 141 are connected to each other, and then flows into the rear chamber 141.

[0079] When the rotation speed of the drum 20 is greater than or equal to the set speed, the water in the cavity 14 is centrifugally located within the cavity 141 and does not flow into adjacent cavities 141 or toward the water outlet 126. When the rotation speed of the drum 20 is less than the set speed, the water in the cavity 14 flows out through the water outlet 126. When the rotation speed of the drum 20 is less than the set speed, the water in the cavity 14 flows toward the cavity 141 near the water outlet 126, and the water in the cavity 141 near the water outlet 126 flows out through the water outlet 126. The distribution of water in the cavity 14 can be controlled by controlling the rotation speed and time of the drum 20 when filling the cavity 14. This can ensure that all cavities 141 are filled with water, that is, the water is primarily located in one or several adjacent cavities 141. The rotation speed of the drum 20 is then controlled to be greater than or equal to the set speed so that the water in the cavity 141 remains within the cavity 141 and does not flow out. This allows for adjustment to various deflection conditions that may occur in the washing machine.

[0080] See also Figure 22-23 As shown, in order to achieve the connection between multiple chambers 141, a water outlet 1193 is provided between two adjacent chambers 141 so that water can flow between adjacent chambers 141; a plurality of chambers 141 connected front to back are provided in the cavity 14, that is, except for the chambers 141 at the front and rear ends, the other chambers 141 have two water outlets 1193. During the rotation of the drum 20, the upper and lower positional relationship between the base 11 and the upper cover 12 will change; the water outlet 1193 is provided at the end of the partition assembly away from the base 11, and the water outlet 1193 is close to the upper cover 12; when the lifting rib structure 10 is at the lower end of the drum 20, the water outlet 1193 is located in the middle of the upper part of the partition assembly. At this time, after the water surface in the rear chamber 141 reaches the water outlet 1193, the water flows into the adjacent previous chamber 141.

[0081] In order to limit the flow of water in the chamber 141 toward the end near the water outlet 126, a guide plate 121 is provided on the upper cover 12 to guide the water in the chamber 141 toward the water outlet 1193 at one end near the water outlet 126. Multiple partition plate assemblies are arranged in parallel in the front-to-back direction. Water flows into the internal waterway 13 from the water inlet 125, then flows into the chamber 141 at the front end, and then flows backward through the water outlet 1193 into each chamber 141 in sequence. The guide plate 121 is an arc-shaped plate extending from the corner of the chamber 141 away from the water outlet 1193 toward the water outlet 1193. The upper cover 12 is provided with left-right symmetrical guide plates 121; each chamber 141 is provided with two guide plates 121, and the guide plates 121 extend obliquely from the left or right angle of the rear of the chamber 141 toward the water outlet 1193.

[0082] See also Figure 20As shown, the internal water channel 13 comprises a main section 131 extending in the front-to-back direction, and a bent section 132 extending along the rear end of the main section 131 toward the water inlet 125. The bent section 132 facilitates water flow from the bent section 132 into the main section 131 when the bent section 132 is located above the main section 131, while also preventing backflow of water within the internal water channel 13. The internal water channel 13 is sealed by an internal water channel groove 133 engaged with the baffle assembly and an internal water channel cover 134 integrally formed on the upper cover 12.

[0083] See also Figures 16-20 As shown, the baffle assembly includes a plurality of bottom baffles 119 disposed on the base 11, a plurality of upper baffles 129 disposed on the upper cover 12 and matched with the bottom baffles 119, and an inner waterway groove 133 is snap-fitted and fixed to the bottom baffles 119. The internal waterway 13 further includes a mounting plate 135 connected to the inner waterway groove 133. The mounting plate 135 extends away from the inner waterway cover 134. The bottom baffle 119 is provided with a first mounting groove 1191 matching the mounting plate 135. The mounting plate 135 is mounted in the first mounting groove 1191. The mounting plate 135 is spaced apart from the bottom surface of the cavity 14, that is, there is a space between the mounting plate 135 and the bottom surface of the cavity 14 for water to flow through.

[0084] Second mounting grooves 118 for mounting the mounting plate 135 are provided on the front and rear wall panels of the base 11 , that is, the front-to-back dimensions of the mounting plate 135 match those of the cavity 14 .

[0085] A notch is formed at the top end of the bottom partition 119, forming a water passage 1193 between the notch and the inner wall of the upper cover 12, connecting the two adjacent chambers 141. The water passage 1190 is divided into two sections, left and right, by the internal water channel 13. Two guide plates 121 are located within each chamber 141, directing water to the two sections of the water passage 1193.

[0086] See also Figure 21 The base 11 is an open top structure, and the upper cover 12 is an open bottom structure. The base 11 and the upper cover 12 are sealed together. The upper cover 12 has a body 120 that is sealed together with the base 11, and an extension portion 128 that extends from the body 120 toward the base 11 and covers the outside of the base 12.

[0087] Example 2

[0088] See also Figure 23 FIG. 1 illustrates a first embodiment of a method for controlling the eccentricity of a washing machine having the above-mentioned eccentricity adjustment assembly. The method for controlling the eccentricity of a washing machine comprises the following steps:

[0089] S10. Before entering the dehydration process, detect the eccentricity of the load in the drum 20. If the eccentricity value is less than the set eccentricity value, enter the dehydration process; otherwise, enter S20 eccentricity type judgment step.

[0090] Specifically, between the water filling and dehydration processes, it is necessary to detect the eccentricity of the load in the drum. Only when it is within the specified eccentricity value can the motor of the drum washing machine run at high speed to dehydrate the clothes in the drum.

[0091] S20 eccentricity type determination, if it is diagonal eccentricity, then proceeds to step S30, if it is front and rear eccentricity, then proceeds to step S40;

[0092] To determine the type of eccentricity, one is diagonal eccentricity, that is, the center of gravity of the load is not on the axis of the drum 20; when washing a lot of clothes, or washing large clothes such as sheets and quilt covers, it is easy to form diagonal eccentricity in the drum; the other is front-to-back eccentricity, that is, the center of gravity of the load is on the axis of the drum 20, but not in the middle of the front-to-back direction. When the center of gravity of the load moves forward, it is front eccentricity, and when the center of gravity of the load moves backward, it is rear eccentricity.

[0093] S30. Determine the lifting rib structure 10 that needs to be increased in weight according to the diagonal eccentricity; start the drum 20 to rotate, and control the water inlet structure 40 to inject water into the lifting rib structure 10 that needs to be increased in weight.

[0094] Specifically, the eccentricity can be corrected by adjusting the weight of one or both lifting rib structures.

[0095] S40 . Fill water into all the lifting rib structures 10 ; start the drum 20 to rotate, and at the same time control the water inlet structure 40 to fill water into all the lifting rib structures 10 .

[0096] Specifically, the front and rear eccentricity can be reduced to less than the set eccentricity value by increasing the weight of all the lifting rib structures 10 and increasing the anti-eccentricity ability; it can also be achieved by adjusting the front and rear positions of the center of gravity of all the lifting rib structures 10 to control the distribution of water injected into all the lifting rib structures 10 in the front and rear directions within the lifting rib structure 10.

[0097] By judging the type of load eccentricity of the washing machine and then adopting different adjustment operations for the front and rear eccentricity and diagonal eccentricity, it is more conducive to correcting the eccentricity, facilitating rapid adjustment and improving the efficiency of eccentricity adjustment.

[0098] The lifting rib structure 10 has a plurality of chambers 141 connected front to back. When the rotation speed of the drum 20 is greater than or equal to the set rotation speed, the water injected into the lifting rib structure 10 sequentially fills the chambers in the front-to-back direction. In other words, the distribution of the water flow in the lifting rib structure 10 in the front-to-back direction can be controlled. When rear eccentricity occurs, by controlling the rotation speed of the drum 20 to be greater than or equal to the set rotation speed, the water flow first fills the front chambers in the lifting rib structure 10, shifting the center of gravity of the lifting rib structure 10 forward, making it easier for the drum 20 to quickly correct the eccentricity and improving the correction speed. If front eccentricity occurs, if the rotation speed of the drum 20 is also controlled to be greater than or equal to the set rotation speed, the center of gravity of the lifting rib structure 10 will shift forward in the early stage of water injection, exacerbating the front eccentricity.

[0099] When the rotation speed of the drum 20 is less than the set speed, the water injected into the lifting rib structure 10 flows into the front chamber 141 and toward the rear chamber 141. In other words, the water injected into the lifting rib structure 10 is distributed as evenly as possible within each chamber 141. During the water injection process, the center of gravity of the lifting rib structure 10 does not move in the front-to-back direction. The set speed is 300 to 600 rpm, preferably 400 to 500 rpm.

[0100] Of course, during the water injection process, the rotation speed of the drum 20 cannot be too slow, otherwise the water cannot be injected into the cavity 10, and the injected water will flow out; during the water injection process of the lifting rib structure 10, the rotation speed of the drum 20 is greater than the minimum water injection speed, and the minimum water injection speed is 100 rpm to 150 rpm.

[0101] The centrifugal water channels 30 are fixed to the rear flange 21 of the drum 20. Multiple centrifugal water channels 30 are coaxially arranged in an arc-shaped structure. The water inlet structure 40 is equipped with a nozzle 41 that sprays water into the water inlet. In step S20, when the centrifugal water channel 30 of the lifting rib structure 10 requiring water injection passes through the nozzle 41, the nozzle 41 is opened; when the centrifugal water channel 30 of the lifting rib structure 10 requiring water injection passes through the nozzle 41, the nozzle 41 is closed. By controlling the opening or closing of the nozzle 41, water can be injected into the lifting rib structure 10 requiring water injection.

[0103] The second embodiment of the eccentricity control method for a washing machine is described. The difference between this embodiment and the first embodiment of the eccentricity control method is that the detection of the eccentricity value is added during the water filling process.

[0104] A method for controlling eccentricity of a washing machine comprises the following steps:

[0105] S10. Before entering the dehydration program, detect the eccentricity of the load in the drum 20. If the eccentricity value is less than or equal to the set eccentricity value, enter the dehydration program; otherwise, enter S20 eccentricity type judgment step.

[0106] Specifically, between the water filling and dehydration processes, it is necessary to detect the eccentricity of the load in the drum. Only when it is within the specified eccentricity value can the motor of the drum washing machine run at high speed to dehydrate the clothes in the drum.

[0108] To determine the type of eccentricity, one is diagonal eccentricity, that is, the center of gravity of the load is not on the axis of the drum 20; when washing a lot of clothes, or washing large clothes such as sheets and quilt covers, it is easy to form diagonal eccentricity in the drum; the other is front-to-back eccentricity, that is, the center of gravity of the load is on the axis of the drum 20, but not in the middle of the front-to-back direction. When the center of gravity of the load moves forward, it is front eccentricity, and when the center of gravity of the load moves backward, it is rear eccentricity.

[0109] S30. Determine the need to increase the weight of the lifting rib structure 10 according to the diagonal eccentricity; start the drum 20 to rotate, the drum speed is less than the set speed, and greater than the minimum water injection speed, while controlling the water inlet structure 40 to increase the weight of the lifting rib structure 10 within the water injection;

[0110] During the water filling process, the eccentricity of the load in the drum 20 is detected. When the eccentricity value is greater than or equal to the set eccentricity value, water filling continues; when the eccentricity value is less than the set eccentricity value, water filling is stopped, and the eccentricity adjustment is completed.

[0111] When the eccentricity value is greater than or equal to the set eccentricity value and the lifting rib structure is filled with water, the water injection is stopped and an alarm is issued.

[0112] S40 to all the lifting rib structure 10 water injection; start the drum 20 rotation, the drum speed is less than the set speed, and greater than the minimum water injection speed, while controlling the water inlet structure 40 to all the lifting rib structure 10 water injection;

[0113] During the water filling process, the eccentricity of the load in the drum is detected. When the eccentricity value is greater than or equal to the set eccentricity value, water filling is continued; when the eccentricity value is less than the set eccentricity value, water filling is stopped, and the eccentricity adjustment is completed.

[0114] When the eccentricity value is greater than or equal to the set eccentricity value and the lifting rib structure is filled with water, the water injection is stopped and an alarm is issued.

[0115] Example 4

[0116] The third embodiment of the washing machine eccentricity control method proposed by the present invention is described. The difference between this embodiment and the second embodiment of the eccentricity control method is that the steps of adjusting the front and rear eccentricities are different. Otherwise, the same structure or method as the first embodiment can be adopted.

[0117] A method for controlling eccentricity of a washing machine comprises the following steps:

[0118] S10. Before entering the dehydration program, detect the eccentricity of the load in the drum 20. If the eccentricity value is less than or equal to the set eccentricity value, enter the dehydration program; otherwise, enter S20 eccentricity type judgment step.

[0119] Specifically, between the water filling and dehydration processes, it is necessary to detect the eccentricity of the load in the drum. Only when it is within the specified eccentricity value can the motor of the drum washing machine run at high speed to dehydrate the clothes in the drum.

[0120] S20 eccentricity type determination, if it is diagonal eccentricity, then proceeds to step S30, if it is front and rear eccentricity, then proceeds to step S40;

[0121] To determine the type of eccentricity, one is diagonal eccentricity, that is, the center of gravity of the load is not on the axis of the drum 20; when washing a lot of clothes, or washing large clothes such as sheets and quilt covers, it is easy to form diagonal eccentricity in the drum; the other is front-to-back eccentricity, that is, the center of gravity of the load is on the axis of the drum 20, but not in the middle of the front-to-back direction. When the center of gravity of the load moves forward, it is front eccentricity, and when the center of gravity of the load moves backward, it is rear eccentricity.

[0122] S30. Determine the need to increase the weight of the lifting rib structure 10 according to the diagonal eccentricity; start the drum 20 to rotate, the drum speed is less than the set speed, and greater than the minimum water injection speed, while controlling the water inlet structure 40 to increase the weight of the lifting rib structure 10 within the water injection;

[0123] During the water filling process, the eccentricity of the load in the drum 20 is detected. When the eccentricity value is greater than or equal to the set eccentricity value, water filling continues; when the eccentricity value is less than the set eccentricity value, water filling is stopped, and the eccentricity adjustment is completed.

[0124] When the eccentricity value is greater than or equal to the set eccentricity value and the lifting rib structure is filled with water, the water injection is stopped and an alarm is issued.

[0125] S40. Inject water into all the lifting rib structures 10; if it is rear eccentric, control the rotation speed of the drum 20 to be greater than or equal to the set rotation speed, and enter step S41; if it is front eccentric, control the rotation speed of the drum to be less than the set rotation speed and greater than the minimum water injection rotation speed, and enter step S42.

[0126] S41 detects the eccentricity of the load in the drum during the water injection process. When the eccentricity value is greater than or equal to the set eccentricity value, continue to inject water; when the eccentricity value is less than the set eccentricity value, stop injecting water to complete the eccentricity adjustment;

[0127] When the eccentricity value is greater than or equal to the set eccentricity value and the lifting rib structure is filled with water, the water injection is stopped and an alarm is issued.

[0128] S42 detects the eccentricity of the load in the drum during the water injection process. When the eccentricity value is greater than or equal to the set eccentricity value, continue to inject water; when the eccentricity value is less than the set eccentricity value, stop injecting water and complete the eccentricity adjustment;

[0129] When the eccentricity value is greater than or equal to the set eccentricity value and the lifting rib structure is filled with water, the water injection is stopped, so that the water in the lifting rib structure flows out.

[0130] If the forward eccentricity cannot be corrected after adding weight to all the lifting rib structures 10, the center of gravity of the lifting rib structure 10 is controlled to move backward, that is, the water in the front chamber 141 of the lifting rib structure 10 is discharged. After the water injection is stopped, the speed of the drum is controlled to be less than the set speed and greater than the minimum water injection speed, and the water in the chamber 141 flows to the rear chamber, and the water in the rear chamber 141 flows out of the cavity 14; that is, the water in the front chamber 141 is reduced and flows out, so that the center of gravity of the lifting rib structure 10 moves backward, correcting the forward eccentricity of the load.
