Description

Technical Field

[0001] This application relates to the field of smart home appliance technology, specifically to a washing machine that can improve the efficiency of clothes drying. Background Technology

[0002] With the continuous development of technology and users' pursuit of a better and more convenient life, washing machines have emerged, solving the tiring household chore of washing clothes and freeing people's hands. Therefore, washing machines have entered thousands of households. During the normal spin-drying cycle of a washing machine, the high-speed rotation causes clothes inside the drum to stick to the walls. Conventional washing machines expel water through the inner drum's drain holes, but the surface of the drum that contacts the laundry lacks these holes. This causes the clothes stuck to the inner drum walls to block the water flow, making it difficult for water to escape from the clothes in the corners and base of the drum, resulting in poor spin-drying performance and affecting the user experience. Summary of the Invention

[0003] To address the aforementioned technical problems, embodiments of this application provide a washing machine.

[0004] The washing machine provided in the first embodiment of this application includes a drum with no dehydration holes on the contact surface between the inner drum and the laundry, and a controller configured to perform the following steps: acquiring a first moisture content of the laundry to be dehydrated in the inner drum and first eccentricity data of the inner drum; determining a first dehydration program based on the first moisture content and the first eccentricity data; controlling the washing machine to execute an agitation program after the first dehydration program is completed, so as to disperse the laundry in the inner drum; and determining a second dehydration program after the agitation program is completed, and controlling the washing machine to execute the second dehydration program.

[0005] In the first embodiment of this application, the first moisture content of the clothes to be spun in the inner drum of the washing machine and the first eccentricity data of the inner drum are obtained. Based on the first moisture content and the first spin-drying program, a first spin-drying program is determined, and the clothes are spun for the first time. After the first spin-drying program is completed, the clothes in the inner drum stick to the wall after the first high-speed spin-drying, blocking the path of water flowing upwards from the inner drum wall. Therefore, the washing machine is controlled to execute an agitation program, causing the clothes that have blocked the water flow path on the inner drum wall after the first spin-drying to disperse. After the agitation program is completed, a corresponding second spin-drying program is determined, and the washing machine is controlled to execute the second spin-drying program, thereby improving the spin-drying effect of the clothes in the inner drum, avoiding the problem of clothes not being fully dried due to sticking to the wall, and improving the user experience.

[0006] In the washing machine provided according to the second embodiment of this application, the controller is further configured to perform the following steps: after the first spin-drying program is completed, obtain the center of gravity position of the clothes in the inner drum; based on the preset mapping relationship between the center of gravity position of the clothes and the rotation amplitude of the drum, determine a target drum rotation amplitude that matches the center of gravity position of the clothes in the inner drum; and determine the agitation program based on the target drum rotation amplitude.

[0007] In the second embodiment of this application, after the first dehydration program is completed, the bus position of the clothes in the inner drum is obtained, and the target rotation amplitude of the inner drum is determined according to the preset mapping relationship between the center position of the clothes and the rotation amplitude of the drum, so as to determine the corresponding agitation program, thereby shaking the clothes in the inner drum apart and avoiding the clothes from sticking to the wall and affecting the dehydration effect.

[0008] In the washing machine provided according to the third embodiment of this application, the controller is further configured to perform the following steps: after the first spin-drying program is completed, obtain the first weight of the clothes in the inner drum; determine a target drum rotation / stop ratio that matches the first weight of the clothes in the inner drum based on a preset mapping relationship between the weight of the clothes and the drum rotation / stop ratio; and determine the agitation program based on the target drum rotation / stop ratio.

[0009] In the third embodiment of this application, after the first dehydration process is completed, the first weight of the clothes in the inner drum is obtained, and a target rotation ratio of the inner drum that matches the first weight of the clothes in the inner drum is determined based on the preset mapping relationship between the weight of the clothes and the rotation ratio of the inner drum. The agitation process is determined based on the target rotation ratio of the inner drum, so that the clothes in the inner drum can be dispersed by the matching target rotation ratio of the inner drum, and the clothes are prevented from sticking to the wall.

[0010] In the washing machine provided according to the fourth embodiment of this application, the controller is further configured to perform the following steps: obtaining the weight of the clothes to be spun in the inner drum; determining a first spin speed upper limit value based on the weight of the clothes to be spun in the inner drum and the first eccentricity data; determining a first spin-drying program based on the first spin speed upper limit value, wherein the highest spin speed in the first spin-drying program does not exceed the first spin speed upper limit value.

[0011] In the fourth embodiment of this application, the upper limit of the first spin speed can be determined according to the weight of the clothes to be spun in the inner drum and the first eccentricity data of the inner drum. The first spin program is then determined based on the upper limit of the first spin speed, so that the maximum spin speed in the first spin program does not exceed the upper limit of the first spin speed. This avoids situations such as the inner drum colliding with the washing machine body or uneven spin-drying caused by the maximum spin speed exceeding the upper limit of the first spin speed during the spin-drying process.

[0012] In the washing machine provided according to the fifth embodiment of this application, the controller is further configured to perform the following steps: determining a first spin-drying time based on the weight of the clothes to be spin-dryed in the inner drum and a first moisture content; and determining a first spin-drying program based on the first spin-drying time.

[0013] In the fifth embodiment of this application, a first dehydration time is determined based on the weight of the clothes to be dehydrated in the inner drum and a first moisture content. A first dehydration program is then determined based on the first dehydration time. After the washing machine executes the first dehydration program for the first dehydration time, the water in the clothes to be dehydrated is discharged, thereby achieving precise control of the washing machine and ensuring the dehydration effect of the clothes to be dehydrated.

[0014] In the washing machine provided according to the sixth embodiment of this application, the controller is further configured to perform the following steps: after the agitation program is completed, obtain the second moisture content of the clothes in the inner drum and the second eccentricity data of the inner drum; determine the second dehydration program based on the second moisture content and the second eccentricity data.

[0015] In the sixth embodiment of this application, after the agitation program is completed, the second moisture content of the clothes in the inner drum and the current second eccentricity data of the inner drum are obtained again to determine the second dehydration program based on the second moisture content and the second eccentricity data, so as to ensure the dehydration effect of the clothes scattered in the inner drum and improve the user experience.

[0016] In the washing machine provided according to the seventh embodiment of this application, the controller is further configured to perform the following steps: after the agitation program is completed, obtain the second weight of the clothes in the inner drum; determine the upper limit of the second spin speed based on the second weight and the second eccentricity data; determine the second spin program based on the upper limit of the second spin speed, wherein the highest spin speed in the second spin program does not exceed the upper limit of the second spin speed.

[0017] In the seventh embodiment of this application, after the agitation program is completed, the second weight of the clothes in the inner drum is obtained again, and the upper limit of the second spin speed is determined based on the second weight and the second eccentricity data. The corresponding second spin program is determined by the upper limit of the second spin speed. On the one hand, this avoids the problem of the inner drum colliding with the washing machine body due to the excessive spin speed of the second spin program; on the other hand, it ensures the spin-drying effect of the clothes in the inner drum.

[0018] In the washing machine provided according to the eighth embodiment of this application, the controller is further configured to perform the following steps: determining a second spin-drying time based on a second weight and a second moisture content of the clothes in the inner drum; and determining a second spin-drying program for the clothes to be spin-dryed based on the second spin-drying time.

[0019] In the eighth embodiment of this application, the second spin-drying time is determined based on the second weight and second moisture content of the clothes in the inner drum, thereby determining the corresponding second spin-drying program. This ensures the spin-drying effect of the clothes in the inner drum and achieves precise control of the spin-drying program, thus improving the intelligence of the washing machine.

[0020] According to the ninth embodiment of this application, the washing machine further includes a drain valve, one end of which is connected to the water outlet of the inner drum.

[0021] In the ninth embodiment of this application, a drain valve is also provided in the washing machine. One end of the drain valve is connected to the water outlet of the inner drum, thereby draining the water inside the inner drum.

[0022] According to the tenth embodiment of this application, the washing machine further includes a puller disposed at the bottom below the inner drum, one end of the puller being connected to the drain valve, and the controller is further configured to perform the following steps: before executing the first spin-drying program, controlling the puller to open the drain valve to drain the inner drum.

[0023] In the tenth embodiment of this application, a puller is provided at the bottom of the inner drum. One end of the puller is connected to a drain valve, so that before the first dehydration program is executed, the puller is controlled to open the drain valve to drain the water in the inner drum, thereby ensuring that the water in the inner drum is drained in time and ensuring the dehydration effect of the clothes in the inner drum.

[0024] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0030] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0031] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0033] In this application, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0034] With the continuous development of technology and users' pursuit of a better and more convenient life, washing machines have emerged, solving the tiring housework of washing clothes in people's daily lives, freeing people's hands, and thus washing machines have entered thousands of households.

[0035] During the normal spin cycle of a washing machine, the high-speed rotation during the spin cycle causes the clothes inside the drum to stick to the walls. This causes the clothes stuck to the walls to block the water flow path, making it difficult for water to be removed from the clothes at the corners of the drum. This results in poor spin-drying performance and affects the user experience.

[0036] To address the aforementioned technical problems, embodiments of this application propose a washing machine capable of spreading out clothes within the inner drum and improving the dehydration effect. This achieves a first dehydration program determined by acquiring the first moisture content of the clothes to be dehydrated within the inner drum and the first eccentricity data of the inner drum. After the first dehydration program is completed, the washing machine is controlled to execute an agitation program to spread out the clothes within the inner drum. After the agitation program is completed, the washing machine is controlled to execute a second dehydration program to perform a secondary dehydration on the spread clothes within the inner drum. This avoids clothes sticking to the drum walls, which would block the water flow path and prevent water from being easily removed from the clothes, thus ensuring the dehydration effect.

[0037] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a washing machine as illustrated in an exemplary embodiment of this application, such as... Figure 1 As shown, the washing machine includes an inner drum 110, a weighing device 120, a controller 130, and a level measuring device 140. The inner drum 110 holds clothes to be spun, the weighing device 120 weighs the clothes in the inner drum 110 to calculate the moisture content of the clothes, the controller 130 is connected to the weighing device 120 to calculate the moisture content based on the weight of the clothes, and the level measuring device 140 measures the eccentricity of the inner drum 110 and reports this information to the controller 130. This controls the spin-drying process of the washing machine. Furthermore, this application can be for common products such as top-loading washing machines or front-loading washing machines, or any device integrating washing functions; this application does not impose any limitations on the product form of the washing machine.

[0038] Specifically, please refer to Figure 2 This application specification uses a pulsator washing machine as an example. Figure 2 In this context, the washing machine 10 may include one or more of the following: Figure 2 As shown, the washing machine 10 includes: an inner drum 110, an outer drum 102, a water-containing cavity 103, a pulsator 104, a drain valve 105, and water outlet holes 111 disposed on the inner wall of the inner drum 110. Multiple water outlet holes 111 are spaced apart on the inner circumferential wall above the inner drum. This increases the flow rate of washing water from the inner drum 110 into the water-containing cavity 103. Simultaneously, the spaced arrangement of the multiple water outlet holes 111, with adjacent water outlet holes still forming a solid structure within the inner circumferential wall of the inner drum 110, allows for controllable influence on the structural strength of the inner drum 110's circumferential wall. Furthermore, the diameter of the water outlet holes should not be too large or too small. Too large a diameter would affect the structural strength of the inner circumferential wall of the inner drum, while too small a diameter would hinder the entry of washing water into the water-containing cavity 103. Generally, a diameter larger than that of the filter holes is sufficient.

[0039] In some feasible embodiments, the inner drum 110 has no dehydration holes on the surface in contact with the laundry. During the high-speed dehydration process, the water in the laundry inside the inner drum 110 rises to a relatively high height along the inner wall of the inner drum 110, and is discharged through the water outlet 111. The water then flows into the drain pipe through the gap between the inner drum 101 and the outer drum 102, thereby achieving the purpose of dehydrating the clothes.

[0040] The embodiments of this application will be described in further detail below with reference to the accompanying drawings in the embodiments of this specification.

[0041] The controller 130 is specifically installed on a circuit board inside the washing machine's casing. It is equipped with a washing machine spin-drying program control circuit composed of electronic components such as a memory. The controller 130 controls the washing machine to perform the corresponding spin-drying and agitation functions by executing control methods stored in the memory. Specifically, the controller 130 is configured to execute steps S310 to S340, detailed below:

[0042] Step S310: Obtain the first moisture content of the clothes to be dehydrated inside the inner drum, and the first eccentricity data of the inner drum.

[0043] First, it should be noted that the moisture content of the clothes to be spun refers to the percentage of the weight of water contained in the clothes to be spun in the washing machine drum to the actual weight of the clothes. In this embodiment, the washing machine also includes a weighing device for measuring the weight of the clothes. The weight of the clothes to be spun is obtained by weighing them using the weighing device, and the weight of the clothes to be washed is obtained by weighing them before starting the washing program (or when the clothes are put into the drum). Therefore, the moisture content of the clothes to be spun can be calculated from the weight of the clothes to be spun and the weight of the clothes to be washed.

[0044] Furthermore, in some feasible embodiments, the moisture content of the garments to be dehydrated can be determined by the material information of the garments. Specifically, different garment materials have different absorbencies, and the moisture content of the garments to be dehydrated can be determined by obtaining the material information of the garments.

[0045] Specifically, due to the eccentricity of the drum, the washing machine will drain all the water from the drum assembly after washing clothes. During the spin-drying process, the washing machine will pass through two to three resonance zones. When passing through the resonance zone, the higher the eccentricity of the washing machine and the greater the tilt of the clothes in the drum assembly to one side, the greater the vibration in the resonance zone. When the vibration reaches a certain value, the washing drum will collide with the outer shell of the washing machine, causing the washing machine to move or generate noise. After draining, the drum assembly will first rotate at a low speed, and the eccentricity of the washing machine will be measured during this time. When the eccentricity is greater than a preset threshold, it is determined that the washing machine cannot perform high-speed spin-drying. At this time, the drum assembly will stop rotating and refill with water. After refilling with water, the washing wings will rotate, and the washing wings will evenly spread the spun clothes with water. The washing machine will drain the water again, rotate the drum assembly at a low speed, and measure the eccentricity again. When the eccentricity is less than the preset threshold, it means that the laundry has been evenly distributed in the drum assembly, and the spin-drying will not cause the aforementioned collision noise problem. At this time, the washing machine will be controlled to perform high-speed spin-drying. However, this control method of the washing machine will cycle through water replenishment and drainage multiple times until the eccentricity drops to a certain value before starting high-speed spin-drying. This will result in high water consumption and longer washing time.

[0046] To avoid collision noise during the spin-drying process, the corresponding spin-drying speed is determined based on the eccentricity data of the washing drum. This ensures that the clothes can be properly spun at high speed during the spin-drying process, which can improve the degree of water eccentricity reduction, reduce the resistance when the washing wing rotates the clothes, and improve the efficiency of clothes dispersion.

[0047] Step S320: Determine the first dehydration process based on the first moisture content and the first eccentricity data.

[0048] As mentioned above, the first dehydration program that can normally dehydrate the clothes inside the inner drum at high speed can be determined based on the first moisture content of the clothes inside the inner drum and the current eccentricity data of the inner drum.

[0049] Furthermore, in some feasible embodiments, the first dehydration program can be determined based on the material information of the clothes to be dehydrated in the inner drum. For example, since different materials can withstand different maximum speeds, the maximum speed limit is determined based on the material information of the clothes to be dehydrated in the inner drum, thereby determining the first dehydration program whose maximum speed does not exceed the maximum speed limit. In addition, in some feasible embodiments, the corresponding first dehydration program can be determined based on the specific value and correspondence between the first dehydration program and the volume of water retained.

[0050] Step S330: After the first spin-drying program is completed, the washing machine is controlled to perform an agitation program to disperse the clothes inside the drum.

[0051] Specifically, after the first spin cycle is completed, the washing machine is controlled to perform an agitation cycle, that is, the washing machine is controlled to rotate the inner drum according to a preset rotation-stop ratio and rotation amplitude, so that the clothes stuck to the wall or clumps inside the inner drum are dispersed.

[0052] In some feasible embodiments, after the first spin-drying cycle is completed, clothes may stick to the washing machine walls. This sticking obstructs the water flow, or the clothes may clump together during high-speed rotation, leading to incomplete dehydration. Therefore, after the first spin-drying cycle is completed, the washing machine can be controlled to execute a corresponding agitation cycle to separate the sticky and clumped clothes.

[0053] Step S340: After the agitation program is completed, the second spin-drying program is determined, and the washing machine is controlled to execute the second spin-drying program.

[0054] Specifically, after the agitation program is completed, the clothes inside the drum have completely dispersed. A second spin-drying program is then determined to remove any remaining moisture from the clothes. For example, after the agitation program is completed, a corresponding second spin-drying program is determined based on factors such as the weight, moisture content, material information, and drum eccentricity data of the clothes inside the drum, to remove any remaining moisture.

[0055] In this embodiment, the first moisture content of the clothes to be dehydrated in the inner drum and the first eccentricity data of the inner drum are obtained to determine the corresponding first dehydration program, ensuring that the clothes to be dehydrated are initially dehydrated. After the first dehydration program is completed, an agitation program is executed to separate the clothes that are stuck to the wall and the clothes that are clumped together in the inner drum. Then, the corresponding second dehydration program is determined to remove the residual water from the clothes in the inner drum, thereby improving the dehydration effect of the clothes in the inner drum, avoiding the problem of clothes sticking to the wall and not being dried, and improving the user experience.

[0056] Furthermore, based on the above embodiments, in one exemplary embodiment provided in this application, the controller 130 is further configured to perform the following steps S410 to S430, which are described in detail below:

[0057] Step S410: After the first dehydration process is completed, obtain the center of gravity position of the inner tube underwear.

[0058] Following the above embodiment, after the first dehydration process is completed, since the high-speed dehydration process will cause the clothes in the inner drum to stick to the wall or clump together, if you want to shake the clothes in the inner drum apart by agitation, you need to determine the center of gravity of the clothes in the inner drum.

[0059] In some feasible embodiments, the center of gravity of the clothes in the inner drum can be determined by the balancing device built into the washing machine, or by the current eccentricity data of the inner drum.

[0060] Step S420: Based on the preset mapping relationship between the center of gravity position of the garment and the rotation amplitude of the garment tube, determine the target rotation amplitude of the garment tube that matches the center of gravity position of the garment inside the inner tube.

[0061] Specifically, the memory of the controller 130 also stores the mapping relationship between the weight of the clothes in the washing machine drum and the drum rotation amplitude, that is, the clothes in the drum can be shaken apart according to the drum rotation amplitude that matches the weight of the clothes.

[0062] Specifically, in some feasible embodiments, after the first dehydration process is completed, the center of gravity position of the clothes in the inner drum is obtained, and a target drum rotation amplitude is determined according to the center position of the clothes, so as to shake apart the clothes that are stuck to the wall or clump together in the inner drum through the target drum rotation amplitude.

[0063] In some feasible embodiments, taking a top-loading washing machine as an example, the rotation amplitude of the drum is achieved by a pulsator inside the drum. For example, based on the preset mapping relationship between the center of gravity position of the clothes and the rotation amplitude of the drum, the rotation amplitude of the target pulsator inside the drum that matches the center of gravity position of the clothes inside the drum is determined, so as to control the pulsator inside the drum to rotate according to the rotation amplitude of the target pulsator.

[0064] Furthermore, in some feasible embodiments, the rotation amplitude of the garment tube does not exceed 360 degrees, that is, the rotation amplitude of the garment tube does not exceed one revolution, and the rotation amplitude of the garment tube includes rotation amplitudes in multiple directions. For example, the garment tube can be controlled to rotate clockwise by a corresponding target rotation amplitude, and then the garment tube can be controlled to rotate counterclockwise by a corresponding target rotation amplitude, so as to fully shake out the clothes inside the garment tube. It should be noted that the rotation amplitudes of the garment tube in multiple directions can be the same or different, and the embodiments of this application do not impose any restrictions here.

[0065] Step S430: Determine the agitation procedure based on the target rotation amplitude of the garment tube.

[0066] As mentioned above, after determining the target rotation amplitude of the clothes drum that can disperse the clothes inside, the corresponding agitation program can be determined based on the target rotation amplitude. This includes ensuring that the highest rotation amplitude of the clothes drum in the agitation program does not exceed the target rotation amplitude, or directly generating the corresponding agitation program based on the determined target rotation amplitude.

[0067] In this embodiment, after the first dehydration program is completed, the bus position of the clothes in the inner drum is obtained, and then the target rotation amplitude of the inner drum that matches the center position of the clothes in the inner drum is determined according to the preset mapping relationship between the center position of the clothes and the rotation amplitude of the drum, so as to determine the corresponding agitation program, thereby shaking the clothes in the inner drum apart and avoiding the clothes from sticking to the wall and affecting the dehydration effect.

[0068] Furthermore, based on the above embodiments, in one exemplary embodiment provided in this application, the controller 130 is further configured to perform the following steps S510 to S530, which are described in detail below:

[0069] Step S510: After the first dehydration process is completed, obtain the first weight of the clothes inside the inner drum.

[0070] Following the above embodiments, after the first spin-drying program is completed, the weight of the clothes in the inner drum can be determined based on the weight of the clothes in the inner drum by the built-in weighing device of the washing machine. In addition, the weight of the clothes in the inner drum can also be determined automatically after the first spin-drying program is completed, based on the specific numerical correspondence between the first spin-drying program and the volume of water retained.

[0071] Step S520: Based on the preset mapping relationship between clothing weight and the rotation-stop ratio of the inner tub, determine the target rotation-stop ratio of the inner tub that matches the first weight of the clothing inside the inner tub.

[0072] Specifically, the main purpose of the agitation process is to disperse clothes that are clinging to the walls or clump together inside the inner drum. Therefore, during the agitation process, if the drum's rotation-to-stop ratio is too large or too small, it will not achieve the desired effect of dispersing the clothes. For example, if the drum's rotation-to-stop ratio is too large, the dispersed clothes will cling to the walls or clump together again; if the ratio is too small, it will not be able to disperse the clinging clothes. Therefore, in some feasible embodiments, a mapping relationship between the weight of the clothes and the drum's rotation-to-stop ratio can be preset. This allows for the determination of a matching target drum rotation-to-stop ratio based on the initial weight of the clothes inside the inner drum, enabling the successful dispersion of clothes that are clinging to the walls or clump together inside the inner drum.

[0073] In some feasible embodiments, taking a top-loading washing machine as an example, the rotation and pause ratio of the pulsator inside the drum of the top-loading washing machine can be determined by preset a mapping relationship between the weight of the clothes and the rotation and pause ratio of the pulsator, thereby controlling the rotation duration and pause duration of the pulsator in the washing machine. For example, based on the determined pulsator rotation and pause ratio, the pulsator in the top-loading washing machine can be controlled to rotate according to the corresponding pulsator rotation and pause ratio after the first spin-drying cycle is completed, so as to disperse the clothes clinging to the inner wall of the drum.

[0074] Step S530: Determine the stirring procedure based on the target spinning drum rotation-to-stop ratio.

[0075] As described in the above embodiments, after determining the target rotation-to-stop ratio of the clothes tubing, a corresponding agitation program can be determined based on the target rotation-to-stop ratio. The highest rotation-to-stop ratio in the determined agitation program cannot exceed the target rotation-to-stop ratio.

[0076] Furthermore, following the above embodiments, in some feasible embodiments, a corresponding target agitation program can be generated based on the determined target rotation-to-stop ratio and target rotation amplitude of the clothes tubing. For example, the target rotation amplitude of the clothes tubing is determined based on the center of gravity position of the clothes inside, and the target rotation-to-stop ratio is determined based on the weight of the clothes inside, thereby generating a corresponding agitation program based on the target rotation amplitude and target rotation-to-stop ratio of the clothes tubing.

[0077] In this embodiment, after the first dehydration process is completed, the first weight of the clothes in the inner drum is obtained. Based on the preset mapping relationship between the weight of the clothes and the drum rotation-stop ratio, a target drum rotation-stop ratio that matches the first weight of the clothes in the inner drum is determined. The agitation process is then determined based on the target drum rotation-stop ratio, so that the clothes in the inner drum can be dispersed by the matching target drum rotation-stop ratio, thus preventing the clothes from sticking to the wall.

[0078] Furthermore, based on the above embodiments, in one exemplary embodiment provided in this application, the controller 130 is further configured to perform the following steps S610 to S630, which are described in detail below:

[0079] Step S610: Obtain the weight of the clothes to be spun inside the inner drum;

[0080] Step S620: Determine the upper limit of the first spin-drying speed based on the weight of the clothes to be dehydrated in the inner drum and the first eccentricity data.

[0081] Specifically, the weight of the clothes to be spun inside the inner drum can be obtained from the built-in weighing device of the washing machine, and the first eccentricity data of the drum can be obtained from the built-in level measuring device of the washing machine. The first eccentricity data refers to the eccentricity of the inner drum after the clothes to be spun are put in, which will limit the spin speed to a certain extent.

[0082] It should be noted that after the washing machine finishes washing clothes, it drains all the water from the drum assembly. During the spin-drying process, the washing machine passes through two to three resonance zones. The higher the eccentricity of the washing machine and the greater the tilt of the clothes to one side during these zones, the greater the vibration. When the vibration reaches a certain value, the outer drum will collide with the washing machine's outer casing, causing the washing machine to move or generate noise. Therefore, after determining the drum eccentricity data, the highest spin speed matching that data must be selected. This highest spin speed is the maximum spin speed beyond which the washing machine cannot perform normal high-speed spin-drying under the current eccentricity data. After determining the highest spin speed, a corresponding target spin-drying program is determined based on this speed. The highest spin speed in this target program cannot exceed the highest spin speed matching the eccentricity data, i.e., the aforementioned first spin speed upper limit.

[0083] Step S630: Determine the first dehydration program based on the first dehydration speed limit value, wherein the highest dehydration speed in the first dehydration program does not exceed the first dehydration speed limit value.

[0084] Considering that the eccentricity of the inner cylinder will increase during the dehydration process, and the dehydration speed will gradually increase from low to high, the highest speed in the first dehydration program should not exceed the upper limit of the first dehydration speed.

[0085] In this embodiment, the upper limit of the first spin speed can be determined based on the weight of the clothes to be spun in the inner drum and the first eccentricity data of the inner drum. The first spin program is then determined based on the upper limit of the first spin speed, so that the maximum spin speed in the first spin program does not exceed the upper limit of the first spin speed. This avoids situations such as the inner drum colliding with the washing machine body or uneven spin-drying caused by the maximum spin speed exceeding the upper limit of the first spin speed during the spin-drying process.

[0086] Furthermore, based on the above embodiments, in one exemplary embodiment provided in this application, the controller 130 in the washing machine is further configured to perform the following steps, detailed below:

[0087] The first dehydration time is determined based on the weight of the clothes to be dehydrated inside the inner drum and the first moisture content;

[0088] The first dehydration procedure is determined based on the first dehydration time.

[0089] Specifically, as described in the above embodiments, the weight of the laundry to be dehydrated is obtained from the weighing device built into the washing machine and the first moisture content of the laundry to be dehydrated is obtained through a corresponding method. The first dehydration time is then determined, and the first dehydration program is determined based on the first dehydration time.

[0090] In some feasible embodiments, the first moisture content of the clothes to be dehydrated can be calculated based on the weight of the clothes to be dehydrated after washing and the weight of the clothes before washing. Since a certain amount of moisture will be retained in the clothes in the inner drum during the dehydration process, the target moisture content of the clothes in the inner drum can be determined. Since the moisture content of the clothes in the inner drum gradually decreases during the dehydration process, the corresponding first dehydration time can be determined based on the target moisture content of the clothes in the inner drum and the first moisture content, and the corresponding first dehydration program can also be determined based on the first dehydration time.

[0091] In addition, in some feasible embodiments, the first upper limit of the spin speed can be determined based on the weight of the clothes to be dehydrated in the inner drum and the first eccentricity data, and the corresponding first spin time can be determined based on the target moisture content of the clothes in the inner drum and the first moisture content, thereby generating a corresponding first spin program based on the first spin time and the first upper limit of the spin speed.

[0092] In this embodiment, the first dehydration time is determined based on the weight of the clothes to be dehydrated in the inner drum and the first moisture content. Then, the first dehydration program is determined based on the first dehydration time. After the washing machine executes the first dehydration program for the first dehydration time, the water in the clothes to be dehydrated is discharged, thereby achieving precise control of the washing machine and ensuring the dehydration effect of the clothes to be dehydrated.

[0093] Furthermore, based on the above embodiments, in one exemplary embodiment provided in this application, the controller 120 of the washing machine is further configured to perform the following steps S710 and S720, which are described in detail below:

[0094] Step S710: After the agitation program is completed, obtain the second moisture content of the clothes in the inner drum and the second eccentricity data of the inner drum;

[0095] Step S720: Determine the second dehydration procedure based on the second moisture content and the second eccentricity data.

[0096] Specifically, as described in the above embodiments, after the washing machine's agitation program is completed, the clothes inside the washing machine drum have already spread out. However, there is still some moisture in the clothes inside the drum. For example, as described in the above embodiments, the current moisture content of the clothes inside the drum is the target moisture content, so the spin-drying program needs to continue.

[0097] For example, after the agitation program is completed, the second moisture content of the clothes in the inner drum is obtained and the second eccentricity data of the inner drum is obtained through the level measuring device built into the washing machine, so as to determine the second dehydration program based on the second moisture content of the clothes in the inner drum and the second eccentricity data of the inner drum, so as to remove the residual moisture of the clothes in the inner drum by executing the second dehydration program.

[0098] In this embodiment, after the agitation program is completed, the second moisture content of the clothes in the inner drum and the current second eccentricity data of the inner drum are obtained again to determine the second dehydration program based on the second moisture content and the second eccentricity data, so as to ensure the dehydration effect of the clothes scattered in the inner drum and improve the user experience.

[0099] Furthermore, based on the above embodiments, in one exemplary embodiment provided in this application, the controller 130 of the washing machine is further configured to perform the following steps S810 to S830, which are described in detail below:

[0100] Step S810: After the agitation process is completed, obtain the second weight of the clothes inside the inner drum.

[0101] As described in the above embodiments, after the washing machine's agitation program is completed, the clothes inside the drum have completely dispersed. The clothes can then be weighed again using the washing machine's built-in weighing device to obtain a second weight. In some feasible embodiments, the second weight of the clothes inside the drum after the agitation program is completed can be calculated based on the second moisture content of the clothes inside the drum after the first spin-drying program and the first moisture content of the clothes inside the drum before the first spin-drying program.

[0102] Step S820: Determine the upper limit of the second dehydration speed based on the second weight and second eccentricity data;

[0103] Step S830: Determine a second dehydration program based on the upper limit of the second dehydration speed, wherein the highest dehydration speed in the second dehydration program does not exceed the upper limit of the second dehydration speed.

[0104] As described in the above embodiments, due to the eccentricity of the drum, the washing machine drains all the water from the drum assembly after washing clothes. During the spin-drying process, the washing machine passes through two to three resonance zones. The higher the eccentricity of the washing machine and the greater the tilt of the clothes in the drum assembly to one side during these zones, the greater the vibration in the resonance zone. When the vibration reaches a certain value, the washing drum will collide with the outer casing of the washing machine, causing the washing machine to move or generate noise. After draining, the drum assembly will first rotate at a low speed, and the eccentricity of the washing machine will be measured during this time. If the eccentricity exceeds a preset threshold, it is determined that the washing machine cannot perform high-speed spin-drying.

[0105] In some feasible embodiments, to avoid collision noise during the spin-drying process, the corresponding spin-drying speed is determined based on the eccentricity data of the drum, so that the clothes to be spun can be spun at high speed normally during the spin-drying process. This can improve the degree of water eccentricity reduction, reduce the resistance when the washing wing rotates the clothes, and improve the efficiency of clothes dispersion. The second spin-drying speed limit can be determined based on the second weight of the clothes in the inner drum after the agitation program is completed and the second eccentricity data of the inner drum, so that the highest spin-drying speed in the selected second spin-drying program does not exceed the second spin-drying speed limit.

[0106] Furthermore, since the first weight of the clothes in the inner drum and the first eccentricity data of the inner drum before the first dehydration cycle are both greater than the second weight of the clothes in the inner drum and the second eccentricity data of the inner drum before the second dehydration cycle, it can be determined that the upper limit of the second dehydration speed is greater than or equal to the upper limit of the first dehydration speed.

[0107] In this embodiment, after the agitation program is completed, the second weight of the clothes in the inner drum is obtained again. The upper limit of the second spin speed is determined based on the second weight and the second eccentricity data. The corresponding second spin program is determined by the upper limit of the second spin speed. On the one hand, this avoids the problem of the inner drum colliding with the washing machine body due to the excessive spin speed of the second spin program. On the other hand, it ensures the spin-drying effect of the clothes in the inner drum.

[0108] Furthermore, based on the above embodiments, in one exemplary embodiment provided in this application, the controller 130 of the washing machine is further configured to perform the following steps S910 and S920, which are described in detail below:

[0109] Step S910: Determine the second dehydration time based on the second weight and second moisture content of the clothes inside the inner drum;

[0110] Step S920: Determine the second dehydration procedure for the garments to be dehydrated based on the second dehydration time.

[0111] Specifically, after the washing machine finishes the agitation program, the clothes in the inner drum of the washing machine are weighed by the built-in weighing device to obtain the second weight of the clothes in the inner drum, and the second moisture content of the clothes in the inner drum is obtained in the manner used in the above embodiment, so as to determine the second dehydration time based on the second weight and the second moisture content of the clothes in the inner drum.

[0112] It is evident that before the first dehydration cycle, the weight and moisture content of the clothes inside the drum were higher than those before the second dehydration cycle. Therefore, in this embodiment, the first dehydration time corresponding to the first dehydration cycle is definitely longer than the second dehydration time corresponding to the second dehydration cycle.

[0113] In some feasible embodiments, following the above embodiments, a second upper limit value for the spin-drying speed can be determined based on the second weight of the clothes in the inner drum and the second eccentricity data, and a corresponding second spin-drying time can be determined based on the second weight of the clothes in the inner drum and the second moisture content, thereby generating a corresponding second spin-drying program based on the second spin-drying time and the second upper limit value for spin-drying.

[0114] In this embodiment, the second spin-drying time is determined based on the second weight and second moisture content of the clothes in the inner drum, thereby determining the corresponding second spin-drying program. This ensures the spin-drying effect of the clothes in the inner drum and achieves precise control of the spin-drying program, thus improving the intelligence of the washing machine.

[0115] Furthermore, based on the above embodiments, such as Figure 3 As shown, in one of the exemplary embodiments provided in this application, the washing machine further includes a drain valve, one end of which is connected to the water outlet of the inner drum.

[0116] Furthermore, in some feasible embodiments, please continue to refer to... Figure 3 The washing machine is also equipped with a puller 106, one end of which is connected to the drain valve 105, so that the controller 130 of the washing machine is also configured to perform the following steps, detailed below:

[0117] Before executing the first spin-drying cycle, the control actuator opens the drain valve to drain the inner drum. Specifically, before executing the first spin-drying cycle, the control actuator opens the drain outlet at the bottom of the inner drum, allowing water discharged from the inner drum due to the weight of the clothes to be spun to flow out through the drain valve. For example, the actuator is located below the washing machine drum and includes a fixed rod penetrating the bottom of the outer drum and a positioning pin nested within the fixed rod. The positioning pin is retractable within the fixed rod, allowing the washing machine's drain valve to open, discharging water from the drum's water-containing chamber due to the weight of the clothes to be spun out of the non-perforated drum.

[0118] In this embodiment, a puller is provided at the bottom of the inner drum. One end of the puller is connected to the drain valve, so that before the first dehydration program is executed, the puller is controlled to open the drain valve to drain the water in the inner drum, thereby ensuring that the water in the inner drum is drained in time and ensuring the dehydration effect of the clothes in the inner drum.

[0119] For further details, please refer to Figure 4 , Figure 4 This is a simplified flowchart illustrating the control process of a washing machine in an exemplary application scenario. For example... Figure 4As shown, the first moisture content of the clothes to be spun in the inner drum of the washing machine is obtained, as well as the first eccentricity data of the inner drum. Due to the eccentricity of the inner drum, it will pass through two to three resonance zones during the subsequent spin-drying process. When passing through the resonance zone, the higher the eccentricity of the washing machine and the greater the tilt of the clothes in the drum assembly to one side, the greater the vibration in the resonance zone. When the vibration reaches a certain value, the washing drum will collide with the outer shell of the washing machine, causing the washing machine to move or generate noise. After draining, the drum assembly will first rotate at a low speed, and the eccentricity of the washing machine will be measured at this time. When the eccentricity is greater than a preset threshold, it is determined that the washing machine cannot perform high-speed spin-drying. Therefore, it is necessary to determine the corresponding first spin-drying speed limit based on the first eccentricity data of the inner drum, so as to determine the corresponding first spin-drying program through the first spin-drying limit. Then, after the first spin cycle is completed, the clothes inside the drum may stick to the sides or clump together. Therefore, the corresponding agitation program can be determined based on the weight and center of gravity of the clothes in the drum. During the agitation program, the clothes in the drum are shaken apart according to the corresponding rotation-stop ratio and rotation amplitude. Then, based on the second moisture content and second weight of the clothes in the drum, a second spin cycle is determined to remove the remaining water, further improving the dehydration effect and preventing clothes from sticking to the sides or clumping, thus improving the user experience.
