Description

Technical Field

[0001] This invention belongs to the field of washing machine technology, specifically, it relates to a control method for a washing machine and a washing machine. Background Technology

[0002] In existing washing machines, when washing small loads, the load inside the drum is difficult to distribute evenly after draining. As a result, during the spin-drying stage, the load tends to stick to one side of the drum wall due to inertia, leading to significant eccentricity of the inner drum. This can cause the outer drum to collide with the cabinet or the entire washing machine to shift during the high-speed spin-drying process. Even washing machines with built-in eccentricity protection programs may fail to reach the set spin-drying speed, or the washing machine may not run the spin-drying program at all, triggering frequent alarms, thus resulting in small loads not being spun dry after washing.

[0003] In existing technologies, when the load becomes unbalanced during the dehydration stage, it can be adjusted to a uniform distribution by rotating the inner drum to disperse the load or by adding a small amount of water to redistribute the load. However, when washing small items, the difference between the load volume and the inner drum capacity may prevent even multiple adjustments from achieving a uniform distribution.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a control method for a washing machine and a washing machine. The washing machine has an eccentric component on the side wall of the inner drum to counteract the eccentricity caused by the load inside the drum when washing small items, so as to ensure that the dehydration process proceeds smoothly.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0007] A method for controlling a washing machine, the washing machine including an inner drum, wherein an eccentric component capable of absorbing water and increasing weight is provided on the side wall of the inner drum;

[0008] The washing machine has a low-load washing program. When the low-load washing program is executed, the washing machine controls the inner drum to rotate until the load inside the drum and the eccentric part are evenly distributed before starting the spin-drying process.

[0009] Furthermore, during the process of controlling the inner drum rotation of the washing machine, the washing machine detects the eccentricity value of the inner drum in real time. When the detected eccentricity value is less than the preset eccentricity value, it is determined that the load inside the drum and the eccentric component are in a uniform distribution state.

[0010] Preferably, during the process of controlling the inner drum rotation of the washing machine, the washing machine detects the torque of the motor driving the inner drum in real time, and calculates the eccentricity value of the inner drum based on the detected torque.

[0011] Furthermore, it includes the following steps:

[0012] 1) The washing machine runs a low-load washing program and then drains.

[0013] 2) Control the inner cylinder to rotate at a set speed V0;

[0014] 3) The washing machine detects the eccentricity of the inner drum and determines whether the detected eccentricity is less than the preset eccentricity.

[0015] 4) If the judgment result is negative, return to step 2); if the judgment result is positive, control the inner cylinder to rotate faster.

[0016] 5) Accelerate the inner drum to the set dewatering speed V 脱 It continues to rotate for a certain period of time;

[0017] 6) The inner cylinder stops rotating, and the dehydration process is complete.

[0018] Furthermore, if the inner cylinder continues to rotate for a preset duration T0 and no uniform distribution of the load and eccentric component is detected inside the cylinder, then a shaking process is performed where the inner cylinder rotates at a certain rotation-to-stop ratio.

[0019] The shaking process lasts for a certain period of time. After the shaking process ends, the inner cylinder is rotated again, and dehydration begins after the load and eccentric parts inside the cylinder are evenly distributed.

[0020] Preferably, if the inner cylinder continues to rotate and no uniform distribution of the load inside the cylinder and the eccentric component is detected within a preset time T0, it is determined whether the number of times the shaking process is executed has reached the first preset number N1.

[0021] If the judgment result is negative, the shaking process is executed; if the judgment result is positive, the washing machine is stopped and a prompt message is issued.

[0022] Furthermore, if the inner cylinder rotates continuously for a preset time T0 and no load and eccentric component are detected to be evenly distributed inside the cylinder, the inner cylinder is controlled to rotate in the opposite direction, and dehydration begins after the load and eccentric component are evenly distributed inside the cylinder.

[0023] Preferably, if the inner cylinder continues to rotate in one direction and no load inside the cylinder and the eccentric part are detected to be evenly distributed within a preset time T0, it is determined whether the number of times the rotation direction of the inner cylinder is changed has reached the second preset number N2.

[0024] If the judgment result is negative, the inner drum will be controlled to rotate in the opposite direction; if the judgment result is positive, the washing machine will be controlled to pause operation and issue a prompt message.

[0025] Furthermore, it also includes obtaining the weight of the load inside the drum, and controlling the washing machine to execute a low-load washing program when the weight is lower than a preset weight.

[0026] Furthermore, after the washing machine is turned on, if it receives a signal from the user to select a low-load washing program, it controls the inner drum to rotate during or after the drainage stage until the load inside the drum and the eccentric part are evenly distributed before starting the spin-drying process.

[0027] Another object of the present invention is to provide a washing machine for implementing the control method of the washing machine described above. The washing machine includes an inner drum and an eccentric member fixedly disposed on the side wall of the inner drum. The eccentric member can increase its own weight by absorbing water.

[0028] Furthermore, a plurality of water-repelling blades are provided on the inner side wall of the inner cylinder, and one of the plurality of water-repelling blades is an eccentric water-repelling blade that can absorb water and increase weight, and the eccentric component is the eccentric water-repelling blade.

[0029] Furthermore, the eccentric water-repellent blade includes a housing and a water-absorbing element disposed inside the housing, the water-absorbing element being able to absorb water to increase its own weight;

[0030] Alternatively, the eccentric water-repellent blade may be made of a material that can absorb water to increase its weight and retain its own hardness after absorbing water.

[0031] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0032] The washing machine of the present invention has an eccentric component on the side wall of the inner drum. The eccentric component can absorb water and increase its weight during the washing / rinsing process. When the washing machine performs a light load washing program, it rotates the inner drum to make the load inside the drum and the eccentric component evenly distributed before starting the spin-drying process. The eccentric component can counteract the eccentricity caused by the load inside the drum and spin-dry synchronously with the load during the spin-drying process, maintaining the balance of the inner drum and ensuring that the spin-drying process proceeds smoothly.

[0033] When the washing machine of the present invention continuously rotates the inner drum for a certain period of time but fails to achieve a uniform distribution of the load inside the drum and the eccentric component, it can adjust the relative position of the load inside the drum and the eccentric component by performing a shaking process or controlling the inner drum to reverse. Then, it checks again whether the load inside the drum and the eccentric component are in a uniform distribution state to determine whether to start spin drying. If the uniform distribution state cannot be achieved after multiple adjustments, the program operation is paused and the user is reminded. The machine has a high degree of automation and reduces the user's operation of the washing machine.

[0034] The washing machine of the present invention can obtain the weight of the load inside the drum and determine whether a low-load washing program needs to be executed based on the weight, which is convenient for users.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0044] In the description of this invention, it should be noted that the terms "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0045] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the term "installation" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] Example 1

[0047] like Figure 1 As shown, this embodiment provides a control method for a washing machine. The washing machine includes an inner drum, and an eccentric component that can absorb water and increase weight is provided on the side wall of the inner drum. The washing machine has a low-load washing program. When executing the low-load washing program, the washing machine controls the inner drum to rotate until the load inside the drum and the eccentric component are evenly distributed, and then begins spin-drying.

[0048] In the above scheme, when the load being washed is a small load or a single item, the washing machine executes a small load washing program. The eccentric component on the inner drum side wall is fixed in position and can absorb washing / rinsing water during the washing / rinsing process, thereby increasing its own weight. Before the high-speed rotation of the inner drum during the spin-drying process, the washing machine controls the rotation of the inner drum to ensure that the load inside the drum and the eccentric component are evenly distributed. The eccentric component can counteract at least part of the eccentricity caused by the load inside the drum, allowing the inner drum to smoothly accelerate to a high speed for spin-drying.

[0049] During the dehydration process, the eccentric component dehydrates synchronously with the load under the high-speed rotation of the inner cylinder, keeping the inner cylinder in a relatively balanced state and ensuring the smooth progress of the dehydration process.

[0050] In this embodiment, the volume and water absorption rate of the eccentric component are fixed, thus ensuring that the weight of the eccentric component after each water absorption remains within a certain range, thereby guaranteeing the counteracting effect of the eccentric component on eccentricity. However, when washing a large load, the weight of the eccentric component differs significantly from the total weight of the load inside the drum. After the large load inside the drum is evenly distributed, the eccentric component will not have a significant impact on the balance of the inner drum.

[0051] In a further embodiment of this invention, the washing machine determines whether the load inside the drum and the eccentric component are evenly distributed by detecting the eccentricity value of the inner drum.

[0052] Specifically, during the process of controlling the inner drum rotation of the washing machine, the washing machine detects the eccentricity value of the inner drum in real time. When the detected eccentricity value is less than the preset eccentricity value, it is determined that the load inside the drum and the eccentric component are in a uniform distribution state.

[0053] Preferably, during the process of controlling the inner drum rotation of the washing machine, the washing machine detects the torque of the motor driving the inner drum in real time, and calculates the eccentricity value of the inner drum based on the detected torque.

[0054] like Figure 1 As shown, the control method for the washing machine described in this embodiment specifically includes the following steps:

[0055] 1) The washing machine runs a low-load washing program and then drains.

[0056] 2) Control the inner cylinder to rotate at a set speed V0;

[0057] 3) The washing machine detects the eccentricity of the inner drum and determines whether the detected eccentricity is less than the preset eccentricity.

[0058] 4) If the judgment result is negative, return to step 2); if the judgment result is positive, control the inner cylinder to rotate faster.

[0059] 5) Accelerate the inner drum to the set dewatering speed V 脱 It continues to rotate for a certain period of time;

[0060] 6) The inner cylinder stops rotating, and the dehydration process is complete.

[0061] In the above scheme, the washing machine starts the drain pump to perform the draining operation after washing / rinsing. If the washing machine is running a low-load washing program, the inner drum is controlled to rotate at a set speed V0 at the end of the draining stage or after draining is completed. During the low-speed rotation of the inner drum, the position of the load inside the drum changes until it is evenly distributed with the eccentric part. Then the inner drum is controlled to accelerate to the set spin-drying speed V. 脱 During dehydration, the load inside the cylinder and the eccentric component dehydrate synchronously in the high-speed rotating inner cylinder. The inner cylinder always maintains a relatively balanced state, and the dehydration process is completed smoothly.

[0062] In a further embodiment, the washing machine also includes a weight sensor, which can be used to obtain the weight of the load inside the drum. When the weight of the load inside the drum is lower than a preset weight, the washing machine is controlled to execute a low-load washing program.

[0063] The washing machine in this embodiment can automatically determine whether to execute a low-load washing program based on the weight of the load inside the drum, which is highly automated and convenient for users.

[0064] In another embodiment, the user can choose whether to execute a low-load washing program by operating the washing machine. Specifically, after the washing machine is turned on, if it receives a signal from the user to select a low-load washing program, it controls the inner drum to rotate during or after the drainage stage until the load inside the drum and the eccentric part are evenly distributed before starting the spin-drying process.

[0065] In this embodiment, the washing machine has an eccentric component on the side wall of the inner drum that can absorb water and increase weight. By rotating the inner drum, the load inside the drum and the eccentric component are evenly distributed before the spin-drying process begins. This allows the eccentric component to counteract the eccentricity caused by the load inside the drum to a certain extent. Simultaneously, the eccentric component spins synchronously with the load inside the drum during the high-speed rotation of the inner drum, ensuring that the inner drum remains relatively balanced throughout the entire spin-drying process, thus guaranteeing smooth spin-drying. This embodiment avoids the situation where small items cannot be evenly distributed inside the drum when washing small loads, preventing successful spin-drying and ensuring that small loads can be successfully spun dry.

[0066] Example 2

[0067] like Figure 2 As shown, this embodiment is a further limitation of the above embodiment one. During the process of controlling the inner drum rotation of the washing machine before starting the spin-drying process, if the inner drum continues to rotate for a preset time T0 and the load inside the drum and the eccentric part are still not detected to be in a uniform distribution state, that is, within the preset time T0, the detected eccentric value is always not lower than the preset eccentric value, then the continuous rotation of the inner drum is paused and the shaking process of the inner drum rotating at a certain rotation-stop ratio is executed.

[0068] The shaking process lasts for a certain period of time. After the shaking process ends, the inner cylinder is rotated again, and dehydration begins after the load and eccentric parts inside the cylinder are evenly distributed.

[0069] When the load inside the drum adheres to the wall, it remains in a fixed position within the inner drum during its low-speed rotation, without changing position as the inner drum rotates. If the load and the eccentric component are located on the same side of the inner drum at this time, it is impossible to control the rotation of the inner drum to achieve a uniform distribution of the load and the eccentric component, thus preventing the dehydration process from starting.

[0070] In this embodiment, the washing machine has a preset duration T0 to handle the above situation. When the inner drum continues to rotate but cannot achieve a uniform distribution of the load inside the drum and the eccentric component, a shaking process is performed where the inner drum rotates at a certain rotation-to-stop ratio. By performing the shaking process, the load adhering to the wall is detached from the side wall of the inner drum, and then the inner drum is controlled to continue rotating again to adjust the position of the load inside the drum so that it is evenly distributed with the eccentric component, and the spin-drying process begins.

[0071] In a further embodiment, if the inner drum continues to rotate and no uniform distribution of the load and eccentric component is detected within a preset time T0, it is determined whether the number of times the shaking process has been executed has reached a first preset number N1. If the determination result is negative, the shaking process is executed; if the determination result is positive, the washing machine is controlled to pause operation and a prompt message is issued.

[0072] In the above solution, if the washing machine fails to evenly distribute the load inside the drum and the eccentric component after multiple attempts at the shaking process, it will pause operation and send a prompt message to the user, reminding them to check and manually distribute the load inside the drum. By presetting a first preset number of times N1, the washing machine avoids situations where the load inside the drum is too firmly attached to the wall, or where the washing machine malfunctions and continuously cycles through the shaking process.

[0073] like Figure 2 As shown, the control method for the washing machine described in this embodiment specifically includes the following steps:

[0074] 1) Control the inner cylinder to rotate at a set speed V0;

[0075] 2) The washing machine detects the eccentricity of the inner drum and determines whether the detected eccentricity is less than the preset eccentricity.

[0076] 3) If the judgment result is yes, then control the inner cylinder to accelerate to the set dewatering speed V. 脱 Perform dehydration; if the result is negative, proceed to step 4.

[0077] 4) Determine whether the duration of continuous rotation of the inner cylinder has reached the preset duration T0. If the determination result is yes, proceed to step 5). If the determination result is no, return to step 1).

[0078] 5) Determine whether the number of times the shaking process is executed, N, is less than the first preset number, N1. If the result is yes, then execute the shaking process and return to step 1) after the shaking process is completed. If the result is no, then control the washing machine to pause operation and issue a prompt message.

[0079] In this embodiment, when the washing machine continuously rotates the inner drum for a certain period of time but fails to achieve a uniform distribution of the load inside the drum and the eccentric component, it automatically executes a shaking process to prevent the spin-drying process from failing to begin due to the load sticking to the wall. The washing machine records the number of times the shaking process is executed. If a uniform distribution cannot be achieved after multiple executions of the shaking process, the program is paused and the user is notified. The washing machine has a high degree of automation, reducing user operation and making it convenient to use.

[0080] Example 3

[0081] like Figure 3 As shown, this embodiment is a further limitation of the above embodiment one. During the process of controlling the inner drum rotation of the washing machine before starting the spin cycle, if the inner drum continues to rotate for a preset time T0 and the load inside the drum and the eccentric part are still not detected to be in a uniform distribution state, that is, within the preset time T0, the detected eccentric value is always not lower than the preset eccentric value, then the inner drum is controlled to rotate in the opposite direction, and the spin cycle begins after the load inside the drum and the eccentric part are in a uniform distribution state.

[0082] When the load inside the drum adheres to the wall, it remains in a fixed position within the inner drum during its low-speed rotation, without changing position as the inner drum rotates. If the load and the eccentric component are located on the same side of the inner drum at this time, it is impossible to control the rotation of the inner drum to achieve a uniform distribution of the load and the eccentric component, thus preventing the dehydration process from starting.

[0083] In this embodiment, the washing machine is preset with a duration T0 to handle the above situation. When the inner drum continues to rotate but fails to achieve a uniform distribution of the load inside the drum and the eccentric component, the inner drum is controlled to rotate in the opposite direction. By changing the rotation direction of the inner drum, it is possible to cause the load attached to the wall to detach from the side wall of the inner drum, thereby achieving a uniform distribution of the load inside the drum and the eccentric component as the inner drum continues to rotate, and starting the spin-drying process.

[0084] In a further embodiment, if the inner drum continues to rotate in one direction and no uniform distribution of the load inside the drum and the eccentric component is detected within a preset time T0, it is determined whether the number of times the inner drum rotation direction has been changed has reached a second preset number N2. If the determination result is negative, the inner drum is controlled to rotate in the opposite direction; if the determination result is positive, the washing machine is controlled to pause operation and a prompt message is issued.

[0085] In the above solution, if the load inside the drum and the eccentric component still cannot be evenly distributed after multiple changes in the inner drum's rotation direction, the washing machine will pause operation and send a prompt message to the user, reminding them to check and manually distribute the load inside the drum. By setting a second preset number of cycles N2, the washing machine avoids the situation where the load inside the drum is too firmly attached to the wall, or the washing machine continuously changes the rotation direction of the inner drum in the event of other malfunctions.

[0086] like Figure 3 As shown, the control method for the washing machine described in this embodiment specifically includes the following steps:

[0087] 1) Control the inner cylinder to rotate at a set speed V0;

[0088] 2) The washing machine detects the eccentricity of the inner drum and determines whether the detected eccentricity is less than the preset eccentricity.

[0089] 3) If the judgment result is yes, then control the inner cylinder to accelerate to the set dewatering speed V. 脱 Perform dehydration; if the result is negative, proceed to step 4.

[0090] 4) Determine whether the duration of continuous unidirectional rotation of the inner cylinder has reached the preset duration T0. If the determination result is yes, proceed to step 5); if the determination result is no, return to step 1.

[0091] 5) Determine whether the number of times N' changes the direction of the inner drum rotation is less than the second preset number N2. If the determination result is yes, control the inner drum to rotate in the opposite direction and return to step 1). If the determination result is no, control the washing machine to pause operation and issue a prompt message.

[0092] In this embodiment, if the washing machine continuously rotates the inner drum for a certain period of time but fails to achieve a uniform distribution of the load inside the drum and the eccentric component, it automatically controls the inner drum to rotate in the opposite direction. This avoids the situation where the load sticks to the wall, preventing the spin-drying process from starting. The washing machine records the number of times the inner drum's rotation direction is changed. If a uniform distribution cannot be achieved after multiple changes in the inner drum's rotation direction, the program is paused and the user is alerted. The washing machine has a high degree of automation, reducing user operation and making it convenient to use.

[0093] Example 4

[0094] like Figure 4 As shown, this embodiment provides a washing machine for implementing the control method described in any of the above embodiments.

[0095] The washing machine includes a casing 1 and an outer drum 2 and an inner drum 3 disposed within the casing 1. The inner drum 3 is rotatably disposed within the outer drum 2. An eccentric component is provided on the side wall of the inner drum 3, which can increase its own weight by absorbing water. The eccentric component is installed on the side wall of the inner drum 3, and its relative position to the inner drum 3 remains unchanged during the rotation of the inner drum 3.

[0096] In a further embodiment, a plurality of water-repelling blades are provided on the inner side wall of the inner cylinder 3, and one of the water-repelling blades is an eccentric water-repelling blade 4 that can absorb water and increase weight, and the eccentric component is the eccentric water-repelling blade 4.

[0097] like Figure 4 As shown, in this embodiment, the eccentric water-repelling blade 4 is disposed in the middle of the side wall of the inner cylinder 3. The eccentric water-repelling blade 4 can also be disposed in the front or rear part of the side wall.

[0098] In a further embodiment, the eccentric water-repellent blade 4 includes a housing and a water-absorbing element disposed inside the housing, wherein the water-absorbing element can absorb water to increase its own weight.

[0099] Specifically, the housing is installed on the side wall of the inner cylinder 3, and a water-permeable hole is provided on the housing. Washing / rinsing water can enter the interior of the housing through the water-permeable hole and come into contact with the water-absorbing element.

[0100] Alternatively, the housing has an opening facing the side wall of the inner cylinder 3, the housing is mounted on the side wall of the inner cylinder 3, and the opening covers a plurality of dewatering holes on the side wall. Washing / rinsing water between the inner cylinder 3 and the outer cylinder 2 enters the interior of the housing through the dewatering holes and comes into contact with the water-absorbing element.

[0101] The absorbent component is a water-absorbing material with a specific water absorption rate, such as an absorbent sponge.

[0102] In another embodiment, the eccentric water-repellent blade 4 is made of a material that can absorb water and increase weight, and can maintain its own hardness after absorbing water.

[0103] In this embodiment, the washing machine has an eccentric component on the side wall of the inner drum 3. The eccentric component can absorb water and increase its weight, thereby forming a uniform distribution with the load inside the drum during the spin-drying process of washing small items, offsetting the eccentricity caused by the load inside the drum, and ensuring the smooth progress of the spin-drying process. By modifying one of the water-repelling blades in the inner drum 3 to form an eccentric water-repelling blade 4 as the eccentric component, no additional structure needs to be added to the inner drum 3, and it will not affect the washing machine's regular washing operation.
