[0002] In the running process of the washing machine, the high rotation speed of the washing machine generates a strong centrifugal force, which can ensure that the clothes in the washing machine achieve the corresponding purpose. For example, when the washing machine performs clothes dehydration, the high rotation speed of the washing machine generates a strong centrifugal force, which can achieve the purpose of dehydrating the clothes; when the washing machine performs clothes drying, the high rotation speed of the washing machine generates a strong centrifugal force, which can achieve the purpose of drying the clothes.

[0057] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0058] The operation control method of the washing machine provided by the embodiments of the present application can be applied to a washing machine as shown in Figure 1In the application environment shown, the washing machine 100 includes a controller 102 and a spray device 104. The controller 102 is used to determine the distribution state of the clothes in the washing machine during operation. When it is determined that the clothes are attached to the inner wall of the inner drum of the washing machine based on the distribution state, it determines whether the clothes are within the spray range of the spray device 104. When it is determined that the clothes are within the spray range, it controls the spray nozzles of the spray device 104 to open and spray the clothes, so that the clothes are removed from the inner wall of the inner drum and the corresponding processing procedure continues.

[0059] In one embodiment, such as Figure 2 As shown, a method for controlling the operation of a washing machine is provided, which can be applied to... Figure 1 Taking controller 102 as an example, the following steps are included:

[0060] S202, during the operation of the washing machine, determine the distribution of clothes in the washing machine.

[0061] During operation, the high-speed rotation of a washing machine generates strong centrifugal force, ensuring that the clothes inside achieve their intended purpose. For example, during the spin-drying process, the high speed generates strong centrifugal force to dehydrate the clothes; during the drying process...

[0062] When drying, the high-speed rotation of the washing machine generates strong centrifugal force, which achieves the purpose of drying clothes. However, the strong centrifugal force generated by the high-speed rotation also causes the clothes to stick to the inner wall of the washing machine drum. This means that during subsequent clothing processing programs, the clothes remain stuck to the inner wall of the drum. After the processing programs are completed, this results in wrinkles and wear and tear on the clothing fibers.

[0063] Therefore, during the washing machine's operation, the distribution of clothes inside is detected to determine whether the clothes are sticking to the inner wall of the drum. If this is confirmed, the system breaks up the sticking, preventing the clothes from adhering to the drum wall during subsequent processing cycles. This avoids wrinkles and fiber abrasion on the clothes after the processing cycle is complete.

[0064] This ensures the quality of clothing after the corresponding processing procedures are completed. For example, ensuring the quality of clothing after the dehydration process (5 minutes) or after the drying process (6 minutes).

[0065] S204, when it is determined from the distribution of clothes that the clothes are attached to the inner wall of the washing machine drum, determine whether the clothes are within the spray range of the spray device inside the washing machine.

[0066] The spray range of the washing machine's spray device is fixed, for example, between 45 and 60 degrees. When it is determined from the distribution of the clothes that they are sticking to the inner wall of the washing machine drum, there is a risk of the clothing fibers being abraded. Therefore, in order to ensure that the clothes are not stuck to the inner wall of the washing machine drum, it is necessary to determine whether the clothes are within the spray range of the washing machine's spray device, i.e., the controller executes S206.

[0067] S206, when it is determined that the clothes are within the spray range, the spray nozzle of the spray device is opened to spray the clothes, so that the clothes are removed from the inner wall of the inner drum and the corresponding processing procedure continues.

[0068] 5. When determining that the clothes are within the spray range of the spray device, in some embodiments, by determining that the clothes are at any angle between 45 degrees and 60 degrees within the spray range of the spray device, the spray nozzles of the spray device are opened to spray the clothes, causing the clothes to fall off the inner wall of the inner drum and continue to undergo the corresponding processing program. This ensures that when the washing machine subsequently executes the corresponding processing program for the clothes, the clothes will not stick to the inner wall of the washing machine drum, avoiding the problems of wrinkles and fiber wear after the corresponding processing program is completed, thereby ensuring the quality of the clothes after the corresponding processing program is completed.

[0069] It's understandable that when a washing machine spins clothes, the clothes detach from the inner wall of the drum and undergo the corresponding spin-drying process. When a washing machine dries clothes, the clothes detach from the inner wall of the drum and undergo the corresponding drying process.

[0070] In summary, Figure 2 In the illustrated embodiment, during the washing machine's operation, the distribution of clothes within the machine is determined. When it is determined that the clothes are adhering to the inner wall of the washing machine drum, it is then determined whether the clothes are within the spray range of the spray device. If the clothes are within the spray range, the spray nozzles of the spray device are opened to spray the clothes, causing them to detach from the inner wall of the drum before proceeding with the corresponding processing program. In this way, by breaking the state of the clothes adhering to the inner wall of the drum during washing machine operation, the clothes will not stick to the inner wall of the drum during subsequent processing programs. This avoids wrinkles and fiber abrasion after the processing programs are completed, thus ensuring the quality of the clothes after the processing programs are finished.

[0071] In one embodiment, the operation control method of the washing machine further comprises: when the laundry is outside the spraying range, controlling the spraying port to be closed until the laundry is in the spraying range, and then controlling the spraying port to be opened. In this way, during the process of the washing machine rotating to dehydrate the laundry or drying the laundry, since the state of some laundry adhering to the inner wall of the inner tub of the washing machine has been broken, when the position of the some laundry adhering to the inner wall of the inner tub of the washing machine is reached again, the spraying port can be controlled to be closed; and by controlling the spraying port to be opened, the other laundry still adhering to the inner wall of the inner tub of the washing machine can be sprayed, so that the whole laundry adhering to the inner wall of the inner tub of the washing machine can be sprayed and fall off from the inner wall of the inner tub, so that when the washing machine performs the corresponding processing program of the laundry subsequently, the laundry will not adhere to the inner wall of the inner tub of the washing machine, avoiding the problems of the laundry being pressed out of wrinkles and the fibers of the laundry being abraded after the corresponding processing program of the laundry is completed, thereby ensuring the quality of the laundry after the corresponding processing program of the laundry is completed.

[0072] In one embodiment, after the step of controlling the spraying port of the spraying device to be opened to spray the laundry when it is determined that the laundry is in the spraying range, the method further comprises: maintaining the rotation speed of the washing machine when the inner tub of the washing machine rotates. In this way, by maintaining the rotation speed of the motor of the washing machine without stopping the rotation of the inner tub of the washing machine, compared with the way of stopping the rotation of the inner tub of the washing machine, on the one hand, the problem of low service life of the motor caused by frequent switching between closing and opening of the motor can be avoided, and on the other hand, the processing efficiency of the washing machine on the laundry can be improved.

[0073] In one embodiment, after the step of controlling the spraying port of the spraying device to be opened to spray the laundry when it is determined that the laundry is in the spraying range, the method further comprises: increasing the rotation speed of the washing machine when the inner tub of the washing machine rotates. In this way, even if the laundry adhering to the inner wall of the inner tub of the washing machine is sprayed with water to achieve the purpose that the laundry will not adhere to the inner wall of the inner tub of the washing machine, by increasing the rotation speed of the washing machine, the processing rate of the washing machine on the laundry can be improved, and at the same time, when the washing machine performs the corresponding processing program of the laundry, the laundry will not adhere to the inner wall of the inner tub of the washing machine, avoiding the problems of the laundry being pressed out of wrinkles and the fibers of the laundry being abraded after the corresponding processing program of the laundry is completed, thereby ensuring the quality of the laundry after the corresponding processing program of the laundry is completed.

[0074] In one embodiment, as shown in FIG. 4, after the step of increasing the rotation speed of the washing machine, the method further comprises the following steps: Figure 3

[0075] S302, record the number of times of increasing the rotation speed of the washing machine.

[0076] ​S304, when the number of times of increasing the rotation speed of the washing machine is less than the preset number of times, returning to the step of determining the distribution state of the laundry in the washing machine during the operation of the washing machine until the number of times of increasing the rotation speed of the washing machine reaches the preset number of times, and then controlling the washing machine to end the corresponding processing program.

[0077] In order to ensure that the processing efficiency of the washing machine on the laundry can be improved, for example, the dehydration efficiency or the drying efficiency of the washing machine on the laundry can be improved, the rotation speed of the washing machine can be increased, and at the same time, in order to ensure that the degree of wear of the fibers of the laundry is not increased after the rotation speed of the washing machine is increased. Therefore, after recording the number of times of increasing the rotation speed of the washing machine, when it is determined that the number of times of increasing the rotation speed of the washing machine reaches the preset number of times, the corresponding processing program of the washing machine is ended. In some embodiments, the preset number of times can be an integer greater than or equal to 3. In this embodiment, the preset number of times is 3.

[0078] In one embodiment, the manner of determining that the laundry adheres to the inner wall of the inner drum of the washing machine according to the distribution state of the laundry includes: when the distribution state of the laundry is balanced, determining that the laundry adheres to the inner wall of the inner drum of the washing machine. Specifically, as shown in Figure 4 A flowchart of a determination manner of the distribution state of the laundry being balanced is provided, which includes the following steps:

[0079] S402, obtaining the motor power of the washing machine.

[0080] In some embodiments, in combination with Figure 1 The detection device is used to obtain the motor power of the washing machine according to the current and voltage generated by the monitoring board during the operation of the washing machine, and send the motor power of the washing machine to the controller, so that the controller obtains the motor power of the washing machine.

[0081] S404, when the motor power is in the preset power interval corresponding to the balanced distribution state of the laundry, determining that the distribution state of the laundry is balanced.

[0082] The higher the degree of the balanced distribution state of the laundry, the greater the motor power. The preset power interval corresponding to the balanced distribution state of the laundry is related to the processing process of the washing machine on the laundry.

[0083] In some embodiments, the preset power interval corresponding to the balanced distribution state of the laundry can be obtained by measuring the voltage and current of the monitoring board during the experimental process of dehydrating the laundry in the washing machine when it is determined that the laundry in the washing machine adheres to the inner wall of the inner drum of the washing machine.

[0084] In some embodiments, the preset power interval corresponding to the balanced distribution state of the laundry can be obtained by measuring the voltage and current of the monitoring board during the experimental process of drying the laundry in the washing machine when it is determined that the laundry in the washing machine adheres to the inner wall of the inner drum of the washing machine.

[0085] In summary, in Figure 4 In the embodiment shown, by acquiring the motor power of the washing machine, and further determining that the clothes distribution state is balanced when the motor power is within the preset power interval corresponding to the balanced clothes distribution state, so that when it is further determined that the clothes are within the spraying range, the spraying opening of the spraying device is opened to spray the clothes, and the clothes continue to be processed after falling off the inner wall of the inner drum. In this way, during the operation of the washing machine, by breaking the state of the clothes adhering to the inner wall of the inner drum, when the washing machine performs the corresponding processing program of the clothes, the clothes will not adhere to the inner wall of the inner drum of the washing machine, thereby avoiding the problem of clothes being pressed out of wrinkles and clothes fiber wear after the corresponding processing program of the clothes is completed, thereby ensuring the quality of the clothes after the corresponding processing program of the clothes is completed.

[0086] In one embodiment, the washing machine further comprises a plurality of sensors arranged on the outer wall of the inner drum, a first detection object arranged at the starting position of the spraying range, and a second detection object arranged at the end position of the spraying range. As Figure 5 As shown, a flowchart for determining whether the clothes are within the spraying range of the spraying device in the washing machine is provided, comprising the following steps:

[0087] S502, acquiring the first position of the sensor detecting the first detection object and the second position of the sensor detecting the second detection object.

[0088] In some embodiments, the first detection object arranged at the starting position of the spraying range can include a first magnet, and the second detection object arranged at the end position of the spraying range can include a second magnet. The sensor arranged on the outer wall of the inner drum can include a Hall sensor, which can convert a changing magnetic field into a voltage value. In order to improve the detection accuracy, a plurality of Hall sensors can be arranged on one circle of the outer wall of the inner drum of the washing machine. The inner wall of the inner drum of the washing machine corresponds to the outer wall of the inner drum of the washing machine, and the inner drum of the washing machine is used to place clothes. When the washing machine performs a dehydration process or a drying process, the clothes in the dehydration process or the drying process will adhere to the inner wall of the inner drum.

[0089] S504, according to the first position and the second position, determining that the clothes adhering to the inner wall of the inner drum of the washing machine between the first position and the second position are within the spraying range of the spraying device.

[0090] In the running process of the washing machine, the voltage value detected by the Hall sensor when reaching the position of the magnet will change abruptly, so the clothes adhering to the inner wall of the inner tub of the washing machine between the first position of the Hall sensor detecting the first detection object and the second position of the Hall sensor detecting the second detection object are determined to be in the spraying range of the spraying device. It can be understood that the Hall sensor detecting the first detection object and the Hall sensor detecting the second detection object can be different at different times.

[0091] In summary, in the Figure 5 In the embodiment shown, by obtaining the first position of the sensor detecting the first detection object and the second position of the sensor detecting the second detection object, and then determining that the clothes adhering to the inner wall of the inner tub of the washing machine between the first position and the second position are in the spraying range of the spraying device according to the first position and the second position. In this way, by controlling the opening of the spraying port, it is possible to break the state of the clothes adhering to the inner wall of the inner tub of the washing machine, so that when the washing machine subsequently performs the corresponding processing program of the clothes, the clothes will not adhere to the inner wall of the inner tub of the washing machine, avoiding the problem of clothes being pressed out of wrinkles and clothes fiber wear after the corresponding processing program of the clothes is completed, thereby ensuring the quality of the clothes after the corresponding processing program of the clothes is completed.

[0092] In combination with the above, in one embodiment, as Figure 6 shown, a flowchart of a running control method of a washing machine is provided, comprising the following steps:

[0093] S602, in the running process of the washing machine, obtaining the motor power of the washing machine.

[0094] In combination with Figure 1 , the washing machine can further include a monitoring board and a detection device, the detection device is used to obtain the motor power of the washing machine according to the current and voltage generated by the monitoring board in the running process of the washing machine, and send the motor power of the washing machine to the controller, so that the controller obtains the motor power of the washing machine.

[0095] S604, determining whether the clothes distribution state in the washing machine is balanced according to the motor power.

[0096] Specifically, when the controller determines that the clothes distribution state in the washing machine is balanced according to the motor power, S606 is executed; when the controller determines that the clothes distribution state in the washing machine is unbalanced according to the motor power, S602 is executed.

[0097] Wherein, the higher the degree of balanced clothes distribution state, the greater the motor power. The preset power interval corresponding to the balanced clothes distribution state is related to the processing process of the washing machine on the clothes.

[0098] In some embodiments, the preset power interval corresponding to the balanced distribution state of the laundry can be obtained by measuring the voltage and current of the monitoring board during the experiment of dehydrating the laundry in the washing machine when it is determined that the laundry is attached to the inner wall of the inner tub of the washing machine.

[0099] In some embodiments, the preset power interval corresponding to the balanced distribution state of the laundry can be obtained by measuring the voltage and current of the monitoring board during the experiment of drying the laundry in the washing machine when it is determined that the laundry is attached to the inner wall of the inner tub of the washing machine.

[0100] S606, whether the laundry is within the spraying range of the spraying device in the washing machine.

[0101] Specifically, when it is determined that the laundry is within the spraying range of the spraying device in the washing machine, S610 to S618 are executed. When it is determined that the laundry is outside the spraying range of the spraying device in the washing machine, S608 is executed.

[0102] In some embodiments, the first detection object arranged at the starting position of the spraying range can include a first magnet, and the second detection object arranged at the ending position of the spraying range can include a second magnet. The sensors arranged on the outer wall of the inner tub can include Hall sensors, which can convert the changing magnetic field into a voltage value when passing through the magnet. In order to improve the detection accuracy, a plurality of Hall sensors can be arranged on one circle of the outer wall.

[0103] During the operation of the washing machine, the voltage value detected by the Hall sensor when it reaches the position where the magnet is located will change abruptly, so the first position of the Hall sensor detecting the first detection object and the second position of the Hall sensor detecting the second detection object can be determined.

[0104] And the second position of the Hall sensor detecting the second detection object, it is determined that the laundry attached to the inner wall of the inner tub of the washing machine within the spraying range of the spraying device between the first position and the second position.

[0105] S608, control the spraying port of the spraying device to be closed.

[0106] S610, control the spraying port of the spraying device to be opened, and spray the laundry.

[0107] S612, increase the rotation speed of the washing machine when the inner tub of the washing machine rotates.

[0108] In combination with S608 and S610, it is to be noted that the timing of increasing the rotation speed of the washing machine when the inner drum of the washing machine rotates is as follows: when the distribution state of the laundry is determined to be balanced during the operation of the washing machine, the entire laundry or part of the laundry attached to the inner wall of the inner drum is caused to fall off the inner wall of the inner drum by controlling the opening and closing of the spray nozzles of the spraying device, and then the rotation speed of the washing machine is increased, or the rotation speed of the washing machine is increased during the process in which the laundry attached to the inner wall of the inner drum falls off the inner wall of the inner drum.

[0109] 5S614, record the number of times of increasing the rotation speed of the washing machine.

[0110] S616, whether the number of times is less than 3.

[0111] Specifically, when the number of times is less than 3, S602 is executed. When the number of times is greater than or equal to 3, S618 is executed.

[0112] S618, control the washing machine to end the corresponding processing program.

[0113] 0In which, the contents of S602 to S618 can be referred to the foregoing description, and will not be repeated here.

[0114] It should be understood that although each step in the flowchart involved in each of the above-described embodiments is shown in sequence according to the arrow, these steps are not necessarily executed in sequence according to the arrow. Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and the execution of these steps

[0115] steps can be executed in other sequences. Moreover, at least part of the steps in the flowchart involved in each of the above-described embodiments can include multiple steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence of these steps or stages is not necessarily sequential, but can be executed in rotation or alternation with at least part of other steps or stages in other steps.
