[0050] In this application, the word "exemplary" is used to mean "used as an example, illustration, or description." Any embodiment described in this application as "exemplary" is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0051] The present application embodiment provides a dehydration control method for a washing machine, which may also be a washing and drying machine, a shoe washing machine for washing shoes, or other washing equipment. Figure 1 , Figure 1 Flow chart of the dehydration control method of the washing machine provided in the embodiment of the present application. The washing machine includes a variable frequency drainage pump and a driving motor of the drum. It should be noted that the variable frequency drainage pump is a water pump driven by a variable frequency motor, which has a variable frequency function and can flexibly adjust its frequency. In addition, the variable frequency drainage pump is used to drain the washing water in the washing machine. The dehydration control method of the present application includes the following steps S101-S103:

[0052] Step S101: when it is detected that the washing machine is currently in a water-carrying dehydration state, obtaining the operating current of the variable frequency drainage pump;

[0053] It should be noted that the dehydration program of a washing machine usually includes drainage, preliminary dehydration, balance detection and high-speed dehydration. In the drainage stage, the variable frequency drainage pump starts to discharge the washing water in the drum through the drainage pipe to the outside of the washing machine; after the drainage is completed, the washing machine starts preliminary dehydration, and the driving motor drives the drum to rotate at a lower speed, using centrifugal force to initially throw out the water in the clothes; after the preliminary dehydration is completed, the washing machine enters the high-speed dehydration stage, and the driving motor drives the drum to rotate at an accelerated speed until it reaches the target speed, and the centrifugal force generated by the high-speed rotation further throws out the water in the clothes.

[0054] The operating current of the variable frequency drainage pump can reflect the working status of the drainage pump. When the variable frequency drainage pump works normally, its operating current should be stable within the rated value range. If the operating current of the variable frequency drainage pump is too low, it may indicate that the drainage pump has not started or the load is too light; if the operating current of the variable frequency drainage pump is too high, it may indicate that the drainage pump is overloaded and there may be too much water in the drainage pump.

[0055] Step S102: determining the current water-on / water-off type of the washing machine according to the operating current;

[0056] The reason for the washing machine to carry water and dehydrate may be abnormal drainage or other reasons. The operating current of the variable frequency drain pump can reflect whether the drain pump is working properly. If the drain pump is working abnormally, the water carrying and dehydration may be caused by abnormal drainage. If the drain pump is working normally, it can be ruled out that the washing machine carrying water and dehydration is caused by abnormal drainage.

[0057] Step S103: adjusting the operating state of the driving motor and / or the variable frequency drainage pump according to the target adjustment strategy matching the water-with-spinning type to drain the water in the washing machine.

[0058] It should be noted that the target adjustment strategy is determined according to the type of dehydration with water. For example, a mapping relationship collection is pre-stored in the washing machine, and the mapping relationship collection includes mapping relationships between multiple preset dehydration types with water and multiple preset adjustment strategies. The dehydration control method of the washing machine of the present application also includes determining the target adjustment strategy corresponding to the dehydration type with water from multiple preset adjustment strategies based on the mapping relationship collection. In this way, different adjustment strategies are adopted for the dehydration with water of the washing machine caused by different reasons, which can more effectively solve the problem of dehydration with water in the washing machine. Whether the residual water in the washing machine can be discharged smoothly is closely related to the speed of the drum and the variable frequency drainage pump. For example, when the amount of water in the drainage pump is too large and the water cannot be drained normally, by reducing the speed of the drum and keeping the drainage pump turned on to reduce the rate at which water enters the drainage pump and maintain the drainage efficiency of the drainage pump, the amount of water in the drainage pump can be gradually reduced, thereby restoring the normal drainage of the drainage pump, and then efficiently solving the problem of dehydration with water in the washing machine.

[0059] The dehydration control method for a washing machine provided in an embodiment of the present application, when it is detected that the washing machine is currently in a dehydration state with water, specifically adjusts the operating states of a driving motor and a variable frequency drainage pump according to the type of dehydration with water, so as to quickly drain the residual water in the washing machine, thereby more efficiently solving the problem of dehydration with water in the washing machine.

[0060] Regarding how to determine the water-in-spinning type of a washing machine, the present application provides the following embodiment, wherein determining the water-in-spinning type of a current washing machine according to the operating current includes:

[0061] Determining whether the operating current exceeds a first preset current;

[0062] If the operating current exceeds the first preset current, the current water-with-dehydration type is determined to be the first type;

[0063] When the water-carrying dehydration type is the first type, adjusting the operating state of the drive motor and / or the variable frequency drainage pump according to the target adjustment strategy matching the water-carrying dehydration type includes:

[0064] The speed of the drive motor is controlled to decrease to a preset target speed, and the speed of the variable frequency drainage pump remains unchanged.

[0065] The operating current of the variable frequency drain pump exceeds the first preset current, indicating that the variable frequency drain pump is in an overloaded state. Due to the excessive amount of residual water in the drum, the drain pump is unable to drain the water immediately, causing the washing machine to be dehydrated. The speed of the drive motor is controlled to be reduced to the preset target speed to reduce the speed of the drum, thereby reducing the centrifugal force acting on the clothes to reduce the water in the clothes from flowing into the drain pump. Among them, the preset target speed can be 1 / 2 times the speed before the speed reduction. The speed of the variable frequency drain pump remains unchanged, so that the variable frequency drain pump maintains its drainage rate. When the water inlet rate of the drain pump decreases and the drainage rate remains unchanged, the excess water in the washing machine can be quickly drained, reducing the load of the drain pump and avoiding the washing machine from being dehydrated.

[0066] In some other embodiments, when the water-injection type is the first type, adjusting the operating state of the drive motor and / or the variable frequency drain pump according to the target adjustment strategy matching the water-injection type may also include controlling the speed of the drive motor to decrease to a preset target speed, while increasing the speed of the variable frequency drain pump. In this way, the water inlet rate of the drain pump can be reduced, while the drainage rate of the drain pump can be increased, so as to quickly drain excess water from the washing machine and reduce the load of the drain pump.

[0067] In some embodiments, determining the current water-in-spinning type of the washing machine according to the operating current further includes:

[0068] Determining whether the operating current is less than or equal to a second preset current, the second preset current being less than or equal to the first preset current;

[0069] If the operating current is lower than or equal to the second preset current, determining that the current water-with-dehydration type is the second type;

[0070] When the water-carrying dehydration type is the second type, adjusting the operating state of the drive motor and / or the variable frequency drainage pump according to the target adjustment strategy matching the water-carrying dehydration type includes:

[0071] The speed of the drive motor is controlled to be reduced to a second target speed, and the speed of the variable frequency drainage pump is controlled to be reduced to a third target speed, until the target duration is reached, and the second target speed is less than the first target speed.

[0072] The operating current of the variable frequency drain pump is less than or equal to the second preset current, indicating that the current variable frequency drain pump is in a low load state. Due to the excessively fast drum speed of the washing machine, part of the washing water remains in the drum and is unable to enter the drain pump as the clothes are constantly swung. The speed of the drive motor and the variable frequency drain pump is controlled to decrease so that the speed of the drum decreases, so that the residual water in the drum flows into the drain pump normally. Subsequently, the drive motor and the variable frequency drain pump are restarted to drain the incoming washing water, solving the problem of water carryover in the dehydration of the washing machine. Preferably, the second target speed and the third target speed are both zero.

[0073] Regarding how to determine whether the washing machine is in a water-carrying dehydration state, the present application provides the following embodiment. Before obtaining the operating current of the variable frequency drainage pump, the dehydration control method of the present application further includes:

[0074] When the washing machine performs a dehydration program, the operating power of the driving motor is obtained;

[0075] Determining whether the operating power exceeds a first preset power;

[0076] If the operating power exceeds the first preset power, it is determined that the washing machine is in a water-carrying and dehydrating state.

[0077] If the operating power of the driving motor exceeds the first preset power, it means that the load of the driving motor of the current washing machine may be too high due to residual washing water, thereby causing an increase in the operating power. The first preset power can be determined based on parameters such as the weight of the load in the drum and the dehydration time.

[0078] Optionally, when the washing machine performs a dehydration procedure, obtaining the operating power of the driving motor includes:

[0079] In response to an execution instruction of a dehydration program, controlling the driving motor to drive the drum to rotate at a first preset acceleration;

[0080] Monitor the speed of the drum;

[0081] After the rotation speed of the drum reaches the first set rotation speed, the drum is controlled to stop accelerating and the operating power of the driving motor is obtained.

[0082] The first set speed may be the highest spin speed of the washing machine. For example, the washing machine first controls the drum to rotate at a preset pre-spin speed for a preset time, and then starts to control the drum to rotate at a first preset acceleration until the first set speed is reached, thereby starting high-speed spin.

[0083] In some embodiments, after adjusting the operating state of the drive motor and / or the variable frequency drainage pump according to the target adjustment strategy matching the water-carrying dehydration type, the dehydration control method of the present application further includes:

[0084] The driving motor is controlled to drive the drum to rotate at a second preset acceleration until the first set speed is reached, and the variable frequency drainage pump is controlled to operate at a second set speed so that the washing machine continues the dehydration process.

[0085] It should be noted that after the target adjustment strategy is implemented for the operating state of the drive motor and the variable frequency drainage pump, the water in the washing machine is drained, and the drive motor and the variable frequency drainage pump are controlled to restart to continue dehydration. During the subsequent dehydration, it is possible to continuously monitor whether the washing machine is in a water-carrying dehydration state again. If so, the operating state of the drive motor and the variable frequency drainage pump can be adjusted again to drain the residual water, thereby improving the dehydration efficiency of the washing machine and avoiding the clothes not being dried, which affects the user experience.

[0086] The second preset acceleration is, for example, smaller than the first preset acceleration. In this way, the drum is prevented from falling into a water-carrying dehydration state again due to excessive acceleration. Preferably, the second preset acceleration is 1 / 2 times of the first preset acceleration.

[0087] For example, see Figure 2 , Figure 2 Another flow chart of the dehydration control method of the washing machine provided in the embodiment of the present application. The dehydration control method of the washing machine includes the following steps S201-S211:

[0088] Step S201: after the dehydration process is started, the drum is controlled to accelerate at a first preset acceleration and the drum speed r is monitored;

[0089] Step S202: determining whether the drum speed r is greater than the first speed r0 and less than or equal to the second speed r1;

[0090] If the drum speed r is greater than the first speed r0 and less than or equal to the second speed r1, the process proceeds to the following step S203, otherwise the process returns to step S201.

[0091] Step S203: monitoring the operating power P of the driving motor;

[0092] Step S204: determining whether the operating power P of the driving motor is greater than a first preset power P0;

[0093] If the operating power P of the driving motor is greater than the first preset power P0, the process proceeds to the following step S205, otherwise, the process returns to step S203;

[0094] Step S205: determining whether the operating current I of the variable frequency drainage pump is greater than a first preset current I0;

[0095] If the operating current I of the variable frequency drainage pump is greater than the first preset current I0, the process proceeds to the following step S206; otherwise, the process proceeds to the following step S207.

[0096] Step S206: controlling the drum speed to decrease to a third speed r2;

[0097] Afterwards, enter the following step S210.

[0098] Step S207: controlling the drum speed to decrease to 0;

[0099] After that, enter the following step S208.

[0100] Step S208: controlling the speed of the variable frequency drainage pump to decrease to 0 and continuing for a first time period;

[0101] After that, enter the following step S209.

[0102] Step S209: Control the variable frequency drainage pump to restart;

[0103] Afterwards, enter the following step S210.

[0104] Step S210: controlling the drum to accelerate to a second speed r1 at a second preset acceleration to continue the dehydration process;

[0105] Afterwards, return to step S203 and at the same time, execute the following step S211.

[0106] Step S211: determining whether the total dehydration time t reaches the preset total time t0;

[0107] If the total dehydration time t reaches the preset total time t0, otherwise, the drive motor and the variable frequency drainage pump are controlled to stop running to end the dehydration program.
