Therefore, there are washing machines with multiple washing modes on the market.

[0003] Although the washing mode of the existing washing machine is various, the washing machine usually goes through washing, rinsing, dehydration and other processes in the washing process, and each process not only takes a lot of time, but also consumes a lot of water and electricity. At the same time, during the washing process of the washing machine, the washing liquid penetrates into the clothes fibers, and it is difficult to remove the residual washing liquid contained in the clothes during the washing process, especially the drum washing machine, which is more difficult to rinse the clothes. The residual washing liquid not only easily damages the clothes, but also easily causes bacterial infection of sensitive groups. Moreover, during the washing process, due to the heavy and thick clothes, the strong water absorption, the unstable leveling, the excessive foam during washing and other factors, the power of the motor during the washing process may be too high, thereby triggering the self-protection of each board of the washing machine, and even triggering the washing machine failure, which causes the interruption of the execution of the washing program, not only affecting the washing effect, but also seriously affecting the user's washing experience.

[0049] Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0050] As Figures 1-2 shown, an embodiment of the present invention provides a washing machine, including a washing machine body, and the washing machine body includes a washing machine housing 5, a detergent box 1, a display screen 2, a door body 3, a drainage component 4, a spray head 6 and an inner tub 8. Among them, the spray head 6 is connected to the water inlet pipeline of the washing machine and is used to spray water droplets onto the clothes in the inner tub 8 of the washing machine. The spray head 6 can cover all parts of the inner tub to ensure the effect of spray rinsing.

[0051] As Figure 2 shown, during spray rinsing, water flows out from the spray head 6, and the spray water droplets 7 fall on the clothes in the inner tub 8 through the spray path to perform spray and rinse on the clothes. The present invention reduces the traditional rinsing process and realizes spray rinsing of clothes through the spray head 6, which not only greatly shortens the washing time, but also saves water and electricity consumption during the washing process.

[0052] Furthermore, the washing machine further includes a controller for controlling the washing machine body. The controller includes a memory, a processor, and a computer program stored on the memory and executable on the processor. When the processor executes the computer program, the steps of the dehydration control method for the washing machine described in the following embodiments are realized, such as: when the washing machine enters the dehydration stage, detecting whether the motor has triggered a drive self-protection speed reduction operation; if the motor has triggered a drive self-protection speed reduction operation, detecting the safe rotational speed of the current motor after the speed reduction operation is completed; judging whether the safe rotational speed is greater than or equal to a preset spray rotational speed; if the safe rotational speed is greater than or equal to the preset spray rotational speed, adjusting the safe rotational speed to the spray rotational speed and performing a spray rinsing operation at the spray rotational speed; after completing the spray rinsing operation, performing a first dehydration operation.

[0053] Figure 3 A flow chart of a laundry machine dehydration control method is shown. As shown in the figure, the laundry machine dehydration control method includes the following steps: Figure 3

[0054] S11, when the laundry machine enters the dehydration stage, detecting whether the motor triggers the drive self-protection speed reduction operation.

[0055] S12, if the motor triggers the drive self-protection speed reduction operation, detecting the safe speed of the current motor after the speed reduction operation is completed.

[0056] It can be understood that when the user uses the laundry machine to wash clothes, if the user over-doses the detergent and the foam is too much, it may cause the power of the motor to be too high when the clothes are dehydrated at high speed, so that the load of the drive module is too large, thereby triggering the self-protection of the drive module of the laundry machine, forcing the motor to reduce speed, triggering the abnormality of the washing equipment, and no longer continuing to execute the washing program, resulting in that the clothes cannot be completely washed and rinsed. Therefore, when the washing equipment enters the dehydration stage, the speed detection is used to detect whether the motor triggers the drive self-protection speed reduction operation, so as to timely monitor the running condition of the laundry machine, so as to further adjust the motor speed to continue to execute the subsequent spraying and rinsing dehydration process after the drive self-protection speed reduction operation is triggered, and avoid interrupting the washing program after the abnormality of the washing equipment occurs.

[0057] In the embodiment of the present application, the safe speed is the maximum speed allowed by the motor after triggering the drive self-protection speed reduction, which is determined based on the motor and the load of the laundry machine.

[0058] S13, judging whether the safe speed is greater than or equal to a preset spraying speed.

[0059] S14, if the safe speed is greater than or equal to the preset spraying speed, adjusting the safe speed to the spraying speed, and executing the spraying and rinsing operation at the spraying speed.

[0060] In the embodiment of the present application, when the safe speed is greater than or equal to the preset spraying speed, it indicates that the laundry machine still has the risk of abnormality when running at the current motor speed, the safe speed is adjusted to the spraying speed, and the spraying and rinsing operation is executed at the spraying speed, which can eliminate the risk of abnormality of the laundry machine. The safe speed is adjusted to the spraying speed specifically by reducing the safe speed to the spraying speed.

[0061] S15, after completing the spraying and rinsing operation, executing a first dehydration operation. Specifically, the first dehydration operation includes adjusting the spraying speed to the safe speed for dehydration. ​

[0062] In the embodiment of the present application, after the spraying rinsing operation is completed, the spraying rotation speed is increased again to the safe rotation speed for re-dewatering.

[0063] In the embodiment of the present application, the spraying rinsing operation comprises: controlling the spraying head arranged in the washing machine to spray water drops on the clothes in the washing machine via the spraying path to realize spraying rinsing of the clothes, and controlling the drain component of the washing machine to be opened to drain the residual water of the spraying rinsing while the spraying rinsing operation is performed, during the dewatering at the spraying rotation speed.

[0064] The present application removes the rinsing process after the washing machine completes the washing stage and enters the dewatering stage, and adopts the spraying rinsing and dewatering to rinse the clothes, that is, rinsing the clothes by spraying during the dewatering process, which can rinse the clothes and save time and water and electricity due to the removal of multiple rinsing in the original program. The clothes are rinsed by spraying and dewatering, after the main washing is drained, the clothes are dewatered at a high rotation speed for a period of time to drain the residual water in the clothes, and then the rotation speed is reduced to a low rotation speed to dewater and spray the clothes. After the main washing is drained, the residual water in the clothes is removed at a high speed, and then the clothes are rinsed and dewatered at a low rotation speed, and the drain valve is opened to directly drain the residual water of the spraying rinsing and dewatering outside the barrel to prevent secondary pollution. In this way, multiple rinsing in the original program is removed, the running time of washing clothes is greatly reduced, and water and electricity are also saved.

[0065] The washing machine dewatering control method, device, washing machine and storage medium provided by the embodiment of the present application reduce the rinsing process during washing, and rinse the clothes by sequentially performing a first dewatering operation, a spraying rinsing operation and a second dewatering operation after the washing machine completes the washing stage, which greatly reduces the running time of washing clothes and saves water and electricity. Meanwhile, the present application detects whether the motor triggers a drive self-protection speed reduction operation when the washing machine enters the dewatering stage; if the motor triggers the drive self-protection speed reduction operation, the safe rotation speed of the current motor is detected after the speed reduction operation is completed; when the safe rotation speed is greater than or equal to a preset spraying rotation speed, the safe rotation speed is adjusted to the spraying rotation speed, and the spraying rinsing operation is performed at the spraying rotation speed; and after the spraying rinsing operation is completed, the first dewatering operation is performed, which solves the problem that the washing machine does not continue to perform the washing program after triggering the drive self-protection and abnormity, and can ensure that the washing program can continue to be performed after abnormity and that the inner drum of the washing machine reaches a reasonable dewatering speed, thereby ensuring the washing and rinsing effects of the clothes.

[0066] Figure 4 Another washing machine dewatering control method provided by the embodiment of the present application is shown, as shown in Figure 4 The method comprises:

[0067] S21. When the washing machine enters the dehydration stage, detect whether the motor has triggered the drive self - protection speed - reduction operation.

[0068] S22. If the motor has triggered the drive self - protection speed - reduction operation, then detect the safe speed of the current motor after the speed - reduction operation is completed.

[0069] S23. Determine whether the safe speed is greater than or equal to the preset spray speed; if the safe speed is greater than or equal to the preset spray speed, execute step S24; if the safe speed is less than the preset spray speed, execute steps S25 - S29.

[0070] S24. When the safe speed is greater than or equal to the preset spray speed, adjust the safe speed to the spray speed and perform the spray rinse operation at the spray speed; after completing the spray rinse operation, perform the first dehydration operation.

[0071] In the embodiment of the present invention, as Figure 5 shown, when the drive module triggers self - protection due to excessive motor power, the drive module will force the motor to reduce speed until the motor reaches the safe speed. At this time, control the motor to maintain this speed for a certain period of time to detect the magnitude of the safe speed V_safe and compare it with the spray speed V2. When the safe speed V_safe ≥ V2, in order to ensure that the power does not increase further, it will not increase the speed to the dehydration speed V3 for dehydration, but directly reduce the speed to the spray speed V2 for spray rinsing. After completing the spray stage, it will increase to the safe speed V_safe for final dehydration until the dehydration process ends. At this time, the final dehydration speed does not increase to V3 because during this dehydration process, the drive module self - protection has been triggered due to excessive motor power. Therefore, in the subsequent process, the motor speed should not exceed the safe speed to ensure that the power failure will not be triggered again during subsequent dehydration. Figure 6 It is the power - speed change curve graph when V_safe ≥ V2.

[0072] S25. When the safe speed is less than the preset spray speed, control the motor to stop rotating.

[0073] S26. After controlling the motor to stop rotating, perform a pre - rinse operation at a preset first speed to remove excessive foam from the clothes.

[0074] S27. After completing the pre - rinse operation, perform an initial dehydration operation at a preset second speed.

[0075] S28. After completing the initial dehydration operation, adjust the second speed to the spray speed and perform the spray rinse operation at the spray speed.

[0076] S29. After completing the spray rinse operation, perform the second dehydration operation.

[0077] In an embodiment of the present invention, the first rotation speed < the spray rotation speed < the second rotation speed; wherein, the value range of the first rotation speed is 0 - 100 rpm, the value range of the spray rotation speed is 100 - 1000 rpm, and the value range of the second rotation speed is 600 - 1600 rpm. In this embodiment, the dehydration stage includes an initial dehydration operation, a spray rinsing operation, and a second dehydration operation. Specifically, performing the initial dehydration operation at the preset second rotation speed means: after pre-rinsing at the preset first rotation speed, increasing the speed to the preset second rotation speed; adjusting the second rotation speed to the spray rotation speed specifically means: decreasing the speed from the preset second rotation speed to the spray rotation speed; performing the second dehydration operation specifically includes: increasing the spray rotation speed to the second rotation speed again for dehydration.

[0078] In an embodiment of the present invention, as Figure 5 shown, when the safety rotation speed V_security < the preset spray rotation speed V2, the drive module triggers self-protection and forced speed reduction due to excessive power at a lower motor rotation speed. At this time, the load of the drive module is much greater than that when V_security ≥ V2, so the risk of its abnormality is greater. Similarly, because the drive module triggered self-protection during the previous dehydration process, the rotation speed during the subsequent dehydration process still cannot exceed the safety rotation speed. At this time, the motor rotation should be immediately stopped to make the inner drum stop rotating. At this time, the load of the drive module is greater, and the amount of foam in the inner drum is excessive, resulting in a sharp increase in the motor power within a short time as the rotation speed increases during dehydration, thus triggering the self-protection of the drive module. Therefore, the spray rinsing operation cannot be directly performed, but instead, water should be re-introduced, and pre-rinsing should be first performed at a low speed V1 to remove excessive detergent residues in the clothes, and then the three operations of spray rinsing and dehydration should be performed until the dehydration stage ends. The pre-rinsing at this time is only to remove excessive foam in the clothes. Compared with conventional rinsing, the pre-rinsing can be completed in a shorter time and with less water intake. In practical applications, technicians can freely set the time and water intake of the pre-rinsing as needed, and the present invention does not make specific limitations in this regard. Specifically, after the pre-rinsing is completed, first drain the water, and then perform the three operations of spray rinsing and dehydration, including increasing the speed to the rotation speed V3 for the initial dehydration operation, decreasing the speed to V2 for the spray rinsing operation, and finally increasing the speed to the rotation speed V3 for the final dehydration operation. Figure 7 It is a curve graph of the power and rotation speed when V_security < V2.

[0079] In this embodiment, V1 < V2 < V3, the rotation speed V1 is in the range of 0 - 100 rpm, preferably 35 - 55 rpm; the rotation speed V2 is in the range of 100 - 1000 rpm, preferably 300 - 800 rpm; the rotation speed V3 is in the range of 600 - 1600 rpm, preferably 800 - 1200 rpm.

[0080] The present application removes the rinsing process in the laundry process, and adopts spray rinsing to remove the rinsed laundry. In the spray rinsing process, the drainage component is opened, and the clean water is sprayed to the laundry on the bottom of the inner drum through the spray head by the water inlet component of the washing machine, the spray water dissolves and dilutes the residual detergent on the laundry, and then is discharged from the washing machine through the drainage component to perform the rinsing process, so as to realize the spray rinsing of the laundry. The present application rinses the laundry by the spray rinsing operation in the dehydration stage, drains water while rinsing, dehydrates the residual water in the laundry at a high rotation speed for a period of time, and then reduces the rotation speed to spray and rinse the laundry, while the drainage component is opened, and the residual water in the spray rinsing is directly discharged out of the drum, which can prevent secondary pollution, remove the multiple rinsing programs arranged in the existing washing machine, greatly reduce the washing time, and also save the water and power consumption.

[0081] The washing machine dehydration control method provided by the embodiment of the present application compares the size of the safe rotation speed after forced speed reduction and the spray rotation speed, when the safe rotation speed is greater than or equal to the spray rotation speed, the subsequent spray rinsing and dehydration operation is continued, and the subsequent dehydration rotation speed does not exceed the safe rotation speed, which can ensure that the washing machine will not fail again due to excessive power; when the safe rotation speed is less than the spray rotation speed, the motor is stopped, and then the spray rinsing and dehydration operation is performed after pre-rinsing to remove a large amount of foam, which can ensure that the program can continue to be executed after the abnormality occurs, and can ensure that the inner drum reaches a reasonable dehydration rotation speed, and ensures the washing and rinsing effect of the laundry.
