[0042] In the embodiments of the present application, a dehydration control method is provided,Figure 1 Fig. 1 is a flowchart of a method for controlling dehydration of a washing machine according to an embodiment of the present application. As shown in Fig. 1, the method comprises the following steps. Figure 1

[0043] S101: determining a first difference value, the first difference value representing a difference between water levels measured by two water level measurement processes when the washing machine is in a dehydration mode.

[0044] Here, when the washing machine is in the dehydration mode, the first difference value is determined by water levels measured by two water level measurement processes, wherein a first water level value is measured by a first water level measurement process, and a second water level value is measured by a second water level measurement process, the first water level measurement process being different from the second water level measurement process, so that the first difference value can be determined by the first water level value and the second water level value measured by the two water level measurement processes, the water level measured by the water level measurement process being the height of water from the inner wall of the inner tub of the washing machine. In actual application, a plurality of first water level values can be obtained in the first water level measurement process, and a plurality of second water level values can be obtained in the second water level measurement process, so that the difference between the plurality of first water level values and the plurality of second water level values can be obtained, and then the average of the difference between the plurality of first water level values and the plurality of second water level values can be determined as the first difference value, so as to improve the accuracy of the first difference value.

[0045] In an embodiment, the two water level measurement processes comprise:

[0046] The first water level measurement process is performed when the inner tub rotates at a first rotational speed, and the second water level measurement process is performed when the inner tub rotates at a second rotational speed, the first rotational speed being less than the second rotational speed.

[0047] Here, when the washing machine is in the dehydration mode, the inner tub of the washing machine dehydrates the laundry at a certain speed, the first water level value is obtained by performing the first water level measurement process when the inner tub rotates at a first rotational speed, and the second water level value is obtained by performing the second water level measurement process when the inner tub rotates at a second rotational speed, so that the first difference value is determined by the first water level value measured by the first water level measurement process and the second water level value measured by the second water level measurement process.

[0048] S102: determining a working state of a traction device of the washing machine according to the first difference value.

[0049] Here, when the washing machine is in the dehydration mode, the water dehydrated from the laundry is discharged from the inner tub to the outer tub of the washing machine, and this water discharge process needs to be matched with the working of the traction device, so as to affect the water level of the inner tub of the washing machine. Therefore, the working state of the traction device of the washing machine can be determined by the obtained first difference value.

[0050] ​In an embodiment, the working state of the traction device includes an open state and a stop state; when the working state of the traction device is the start state, the drain opening arranged on the inner drum of the washing machine is open; when the working state of the traction device is the stop state, the drain opening is closed.

[0051] Here, the working state of the traction device can reflect the state of the drain opening arranged on the inner drum of the washing machine, wherein when the working state of the traction device is the start state, the drain opening is open, and the water in the inner drum of the washing machine can flow out to the outer drum of the washing machine through the drain opening; when the working state of the traction device is the stop state, the drain opening is closed, and the entire inner drum of the washing machine is in a closed state, and the water in the inner drum of the washing machine cannot flow out to the outer drum of the washing machine through the drain opening, so that the drain opening arranged on the inner drum of the washing machine can avoid the water in the inner drum of the washing machine contacting the dirt between the inner wall of the inner drum of the washing machine and the inner wall of the outer drum of the washing machine during the washing process, and the clothes are kept clean. In actual application, when the working state of the traction device is the start state, the drain opening will be open, and the water in the inner drum of the washing machine can flow out to the outer drum through the drain opening, so that the water level in the inner drum of the washing machine will be lowered, and when the working state of the traction device is the stop state, the drain opening will be closed, and the water in the inner drum of the washing machine cannot flow out to the outer drum of the washing machine through the drain opening, so that the water level in the inner drum of the washing machine changes little, and therefore, the working state of the traction device of the washing machine can be determined by the water level difference of the inner drum of the washing machine.

[0052] In an embodiment, as shown in Figure 2 the first difference, the working state of the traction device of the washing machine is determined, including:

[0053] S201: When the first difference is greater than the first set value, it is determined that the working state of the traction device is the open state.

[0054] Here, when the working state of the traction device is the open state, the water in the inner drum of the washing machine can be drained to the outer drum of the washing machine, and accordingly, the water level in the inner drum of the washing machine will be lowered, so when the first difference is greater than the first set value, it can be determined that the water in the inner drum of the washing machine is drained to the outer drum of the washing machine, and further, it can be determined that the working state of the traction device is the open state.

[0055] S202: When the first difference is less than the first set value, it is determined that the working state of the traction device is the closed state.

[0056] Here, when the working state of the traction device is the stop state, the water in the inner drum of the washing machine is hardly drained to the outer drum of the washing machine, and correspondingly, the water level in the inner drum of the washing machine is kept relatively stable, so when the first difference is less than the first set value, it can be determined that the water in the inner drum of the washing machine is not drained to the outer drum of the washing machine, and further, it can be determined that the working state of the traction device is the stop state.

[0057] In an embodiment, as shown in Figure 3 When the first difference is less than the first set value, determining that the working state of the traction device is the closed state comprises:

[0058] S301: When the first difference is less than the first set value, determining a second difference based on the water level measured by the two water level measurement processes again.

[0059] Here, when the water level measured by the two water level measurement processes is inaccurate, the working state of the traction device determined according to the first difference will be inaccurate, in order to prevent misjudgment caused by inaccurate water level, when the first difference is less than the first set value, the water level is measured again by the two water level measurement processes, so as to determine the second difference according to the water level measured by the two water level measurement processes again. In practical applications, the speed of the inner drum of the washing machine is adjusted to the first rotating speed, the third water level value is measured by the third water level measurement process, and then the speed of the inner drum of the washing machine is adjusted to the second rotating speed, the fourth water level value is measured by the fourth water level measurement process, and the second difference is determined by the third water level value and the fourth water level value. In practical applications, in order to further ensure the accuracy of the working state of the traction device, the working state of the traction device can also be determined by the difference corresponding to the water level measured by multiple water level measurement processes.

[0060] S302: When the second difference is less than the first set value, it is determined that the working state of the traction device is the closed state.

[0061] Here, if the second difference is less than the first set value, there are two water level differences less than the first set value, and it can be determined that the working state of the traction device is in the closed state.

[0062] In an embodiment, after determining the working state of the traction device of the washing machine according to the first difference, the method further comprises:

[0063] Determining whether the washing machine stops the dehydration mode according to the working state of the traction device.

[0064] Here, since the working state of the traction device can control the opening and closing of the drain port, the opening and closing of the drain port will affect the water discharge of the inner drum of the washing machine, and in the process of dehydration, the water discharged from the clothes needs to be discharged, therefore, it is necessary to determine whether the condition of continuing to execute the dehydration mode is met according to the working state of the traction device, and then determine whether the washing machine stops the dehydration mode. In practical application,

[0065] In an embodiment, as shown in Figure 4 determining whether the washing machine stops the dehydration mode according to the working state of the traction device comprises:

[0066] S401: In the case that the working state of the traction device is the open state, it is determined that the washing machine executes the first dehydration mode.

[0067] Here, in the case that the working state of the traction device is the open state, it means that the drain port is opened, and the water in the inner drum of the washing machine can be discharged to the outer drum of the washing machine through the drain port, which meets the condition of continuing to execute the dehydration, therefore the washing machine can continue the dehydration process, and execute the dehydration process in the first dehydration mode. In practical application, when the washing machine executes the first dehydration mode, the speed of the inner drum of the washing machine is kept at a set third speed, and the water in the clothes is discharged through the third speed of the inner drum, and the water discharged from the clothes is discharged to the outer drum of the washing machine through the drain port of the inner drum of the washing machine. The drain pump is started to discharge the water in the outer drum of the washing machine to the outside of the washing machine.

[0068] S402: In the case that the working state of the traction device is the closed state, it is determined that the washing machine stops the dehydration mode or executes the second dehydration mode; wherein,

[0069] The inner drum rotation speed corresponding to the second dehydration mode is lower than the inner drum rotation speed corresponding to the first dehydration mode.

[0070] Here, when the working state of the traction device is the closed state, it indicates that the drain port is closed and the water in the inner drum cannot be drained to the outer drum, and it is determined that the washing machine stops the dehydration mode. In actual application, when the washing machine stops the dehydration mode due to the closed state of the traction device, an alarm sound or other prompt information can be sent to prompt that the washing machine has a fault. In actual application, since the drain port arranged on the inner drum has a gap in mechanical structure, when the inner drum is matched with a low speed of the washing machine, the water in the inner drum can be drained to the outer drum through the gap, and therefore a second dehydration mode can be selected to be executed to complete the dehydration treatment of the clothes. When the washing machine executes the second dehydration mode, the speed of the inner drum is adjusted to a fourth speed, and the fourth speed is lower than the third speed. By prolonging the dehydration time and matching the fourth speed, the water drained from the clothes through the gap of the inner drum is drained to the outer drum, and the drain pump is controlled to be started to drain the water in the outer drum to the outside of the washing machine. In actual application, after the second dehydration mode is ended, the washing machine can also send an abnormal prompt signal to prompt that the washing machine has a fault, so that the washing machine can be repaired as soon as possible.

[0071] In an embodiment, before the determining the first difference, the method further comprises:

[0072] Draining the water in the inner drum.

[0073] Here, before the washing machine enters the dehydration mode, the water in the inner drum of the washing machine needs to be drained. In actual application, before entering the dehydration mode, the clothes are washed for the last time, and after the washing is completed, the water in the inner drum needs to be drained before the dehydration treatment of the clothes is started.

[0074] In an embodiment, the method further comprises:

[0075] Controlling the drain pump of the washing machine to stop working.

[0076] Here, since the water in the inner tub of the washing machine will be emptied before the washing machine is in the dehydration mode, the water in the inner tub of the washing machine will first be drained to the outer tub of the washing machine, and the water in the outer tub of the washing machine will be drained to the outside of the washing machine by starting the drain pump. When the washing machine is in the dehydration mode, the working state of the traction device needs to be determined. When the working state of the traction device is in the starting state, the drain port on the inner tub of the washing machine is opened, so that the water in the inner tub of the washing machine can be drained to the outer tub through the drain port, and thus the drain pump needs to be started. When the working state of the traction device is in the stopping state, the drain port on the inner tub of the washing machine is closed, so that the water in the inner tub of the washing machine cannot be drained to the outer tub through the drain port, and thus the drain pump does not need to be started. Therefore, when the washing machine is in the dehydration mode and before the working state of the traction device of the washing machine is determined, the drain pump needs to be controlled to stop working, and after the working state of the traction device of the washing machine is determined, the drain pump is further controlled accordingly.

[0077] In the above embodiment, the working state of the traction device of the washing machine is determined by the water level difference of the inner tub of the washing machine, and then it can be further determined whether the condition for performing the dehydration treatment is met, so as to effectively control the dehydration mode of the washing machine, thereby ensuring the cleanliness of the clothes during the washing process, and further ensuring that the clothes are successfully subjected to the dehydration treatment.

[0078] The application also provides an application example, as shown in Figure 5 , a dehydration flowchart is shown. Figure 5

[0084] S506: It is judged whether a first difference between the first water level value and the second water level value is greater than a first set value.

[0085] S507: In the case where the first difference is greater than the set value, it is determined that the working state of the traction device is in the starting state.

[0086] S508: The speed of the inner tub is adjusted to a third speed, and the drain pump is started.

[0087] ​S509: In a case where the first difference is less than the first set value, determining whether a determination number is greater than a second set value, wherein the determination number refers to a number of times of determining that the first difference is less than the first set value.
