Technical Field

[0069] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. When the description below refers to the drawings, identical numbers in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0070] It should be noted that, in this document, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0071] In the related art, a washing machine can defoam the foam on clothes according to a pre-set number of defoaming cycles. For example, if the pre-set number of defoaming cycles is 3, the washing machine will defoam the clothes 3 times during each wash cycle. However, the amount of foam in the clothes varies between washes, and the washing machine cannot accurately defoam the clothes according to a fixed number of defoaming cycles. For example, if there is a lot of foam in the clothes, the washing machine cannot effectively eliminate the foam according to a fixed number of defoaming cycles; if there is less foam in the clothes, the washing machine will waste resources according to a fixed number of defoaming cycles. This results in poor flexibility in controlling defoaming in the washing machine.

[0072] In order to solve the technical problem of poor flexibility in controlling defoaming in washing equipment in the related art, an embodiment of the present application provides a control method for washing equipment. At the end of rinsing, the first water level in the washing tub of the washing equipment is obtained. The foam value of the water in the washing tub can be accurately determined based on the first water level. Then, the operating mode of the washing equipment is determined based on the foam value. When the foam value is low, the washing equipment is controlled to enter the dehydration mode. When the foam value is high, if the power of the motor of the washing equipment is greater than a preset power, it means that the foam value in the water affects the dehydration of the washing equipment. The washing equipment enters the defoaming mode, thereby reducing the foam in the water in the washing tub. In this way, the washing equipment can flexibly control the defoaming of the washing equipment according to the foam value of the water in the washing tub in real time, thereby improving the flexibility of the washing equipment in controlling defoaming.

[0073] Next, combine Figure 1 , introduces the application scenarios to which the embodiments of this application are applicable.

[0074] Figure 1This is a schematic diagram of an application scenario provided by an embodiment of this application. Figure 1 , including: a washing device. At the end of the washing stage of the washing device, the washing device obtains a first water level frequency, and determines a foam value based on the first water level frequency. The washing device determines a working mode of the washing device based on the foam value, and operates according to the working mode. Among them, the working mode includes a defoaming mode, a dehydration mode, and an alarm mode. The washing device can flexibly control the working mode of the washing device according to the foam value of the water in the washing tub in real time. When the foam value is high, the washing device defoams the foam according to the defoaming mode, thereby improving the flexibility of the washing device in controlling defoaming.

[0075] The technical solutions shown in this application are described in detail below through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other, and the same or similar contents will not be repeated in different embodiments.

[0076] Figure 2 This is a flow chart of a control method for a washing machine provided in an embodiment of the present application. Figure 2 , the method may include:

[0077] S201. At the end of a washing phase of a washing device, obtain a first water level frequency in a washing tub of the washing device.

[0078] The execution subject of the embodiment of the present application can be a washing machine, or a washing machine control device provided in the washing machine. Optionally, the washing machine control device can be implemented by software, or by a combination of software and hardware.

[0079] The washing device can be any device with a washing function. For example, the washing device can be a washing machine. For example, the washing device can be a pulsator washing machine, an agitator washing machine, a drum washing machine, an ultrasonic washing machine, etc. Optionally, the washing device includes a washing tub. The washing tub is used to wash laundry. For example, a user can place laundry in the washing tub, and the washing machine can rotate the washing tub to wash the laundry in the washing tub.

[0080] The washing phase is used to remove stains from clothing. For example, during the washing phase, a washing machine may use a mixture of water and detergent to clean clothing, thereby removing stains from clothing. For example, a drum washing machine may rotate the drum to allow the water and detergent mixture to wash clothing.

[0081] The water level frequency can be the resonant frequency output by a sensor. For example, the water level frequency can be the resonant frequency output by a water level sensor in a washing machine. Alternatively, the water pressure within the washing tub can be detected by the water level sensor. When the water pressure changes, the inductance in the water level sensor changes, and the water level frequency of the washing machine is determined via a parallel capacitor. The first water level frequency is the water level frequency output by the water level sensor at the end of the wash cycle. For example, if the water level frequency output by the water level sensor at the end of the wash cycle is F1, then the first water level frequency is F1.

[0082] Optionally, the water level in the washing tub can be determined based on the water level frequency. For example, when the water level in the washing tub changes, the air pressure in the washing tub also changes, and the water level frequency output by the water level sensor also changes. The water level in the washing tub is determined based on the water level frequency and the corresponding relationship between the water level frequency and the water level. The corresponding relationship between the water level frequency and the water level includes at least one water level frequency and the water level corresponding to each water level frequency. The water level frequency is inversely proportional to the water level in the washing tub. For example, when the water level in the washing tub rises, the air pressure in the washing tub increases, and the water level frequency output by the water level detection sensor decreases. When the water level in the washing tub decreases, the air pressure in the washing tub decreases, and the water level frequency output by the water level sensor increases.

[0083] S202: Determine the foam value of the water in the washing tub according to the first water level frequency.

[0084] The foam value indicates the amount of foam in the water. For example, a higher foam value indicates more foam in the water, while a lower foam value indicates less foam. Alternatively, the amount of foam in the tub can alter the air pressure within the tub, thereby changing the water level frequency measured by the water level sensor. For example, when the tub rotates, a large amount of foam is generated. This increased foam increases the air pressure within the tub, which in turn decreases the water level frequency.

[0085] In actual application, the rising water level will also cause the water level frequency to decrease, but at the end of the washing stage, no water is added to the washing tub, so the water in the washing tub will not cause the water level frequency to decrease.

[0086] Optionally, at the end of the washing phase, based on the first water level frequency, the foam value in the washing tub can be determined according to the following feasible implementation: a first preset relationship between the water level frequency of the washing device and the foam value of the water in the washing tub is obtained. The first preset relationship includes at least one water level frequency and the foam value corresponding to each water level frequency. For example, the first preset relationship between the water level frequency and the foam value can be as shown in Table 1:

[0087] Table 1

[0088] Water level frequency Foam value Frequency 1 Foam value 1 Frequency 2 Foam value 2 Frequency 3 Foam value 3 …… ……

[0089] It should be noted that Table 1 is only an example of the first preset relationship between the water level frequency and the foam value, and is not intended to limit the first preset relationship between the water level frequency and the foam value.

[0090] The foam value of the water in the washing tub is determined based on the first water level frequency and the first preset relationship. For example, at the end of the washing phase of the washing apparatus, if the first water level frequency is frequency 1, the foam value of the water in the washing tub is foam value 1; if the first water level frequency is frequency 2, the foam value of the water in the washing tub is foam value 2; and if the first water level frequency is frequency 3, the foam value of the water in the washing tub is foam value 3.

[0091] Optionally, the foam value is inversely proportional to the water level frequency. For example, when the foam value of the water in the washing tub increases, the air pressure in the washing tub increases, and the water level frequency output by the water level detection sensor decreases; when the foam value of the water in the washing tub decreases, the air pressure in the washing tub decreases, and the water level frequency output by the water level sensor increases.

[0092] S203: Determine the operating mode of the washing device according to the foam value of the water in the washing tub.

[0093] The working mode is a defoaming mode, a dehydration mode or an alarm mode. Among them, the defoaming mode is used to eliminate foam in the water. Optionally, when the working mode of the washing device is the defoaming mode, the washing device can drain the water with foam in the washing tub and use clean water to wash the foam on the clothes. For example, when the working mode of the washing device is the defoaming mode, the motor of the washing tub stops running, the washing tub is stationary, and the drain pump of the washing device is turned on, so that the water in the washing tub is completely drained out of the washing tub. When the water in the washing tub is drained out of the washing tub, the drain pump of the washing device is turned off, and the water inlet valve is opened, so that clean water can wash the foam on the clothes. When the water level in the washing tub reaches a preset position, the water inlet valve of the washing device is closed, and the drain pump of the washing device is turned on again to drain the water out of the washing tub. In this way, the foam on the clothes can be treated by washing with clean water.

[0094] Optionally, when the drain pump is draining, it can operate according to a preset operating time. For example, if the preset operating time is 2 minutes, the drain pump will turn off after 2 minutes. Optionally, when the water inlet valve is open, the water inlet valve can determine the operating time based on the water inflow rate and the preset position. For example, the preset position can be one-third of the washing tub, and the water inlet valve closes when the water level reaches one-third of the washing tub.

[0095] The spin mode is used to spin dry the clothes. For example, when the washing machine is in the spin mode, the washing tub of the washing machine rotates at high speed to remove moisture from the clothes inside the tub. Alternatively, when the washing machine is in the spin mode, the washing machine operates at a preset spin speed. For example, if the preset spin speed is 800 rpm, the washing tub of the washing machine will rotate at 800 rpm when the washing machine enters the spin mode.

[0096] The alarm mode is used to indicate that a washing machine malfunctions. For example, when a washing machine malfunctions, the operating mode of the washing machine is in alarm mode, and the washing machine can generate an alarm message to alert the user that the washing machine has malfunctioned. Optionally, the alarm message can be a voice prompt. For example, when the operating mode of the washing machine is in alarm mode, the washing machine can generate a voice message to alert the user that the washing machine has malfunctioned. Optionally, the alarm message can be a buzzer prompt. For example, when the operating mode of the washing machine is in alarm mode, the washing machine can generate a buzzer prompt to alert the user that the washing machine has malfunctioned. For example, when the operating mode of the washing machine is in alarm mode, the washing machine can generate a 30-second buzzer prompt, or it can generate two buzzer prompts within 10 minutes, with each buzzer prompt lasting one minute.

[0097] The working mode of the washing equipment is determined according to the foam value of the water in the washing tub. There are two situations as follows:

[0098] Case 1: The foam value is less than or equal to the preset threshold.

[0099] When the foam value is less than or equal to a preset threshold, the washing machine is determined to be in the spin mode. For example, when the foam value is less than or equal to the preset threshold, it indicates that there is little foam in the water in the washing tub, and the foam will not affect the cleanliness of the clothes or interfere with the spin speed of the washing machine. In this case, the washing machine can enter the spin mode to spin the clothes.

[0100] In this case, if the foam value is less than or equal to the preset threshold, the washing machine can skip the defoaming mode and directly enter the dehydration mode, which can reduce the power consumption of the washing machine and improve the flexibility of the washing machine control.

[0101] Case 2: The foam value is greater than the preset threshold.

[0102] When the foam value exceeds a preset threshold, the operating mode of the washing machine can be determined according to the following feasible implementation: a first power of the washing tub motor is obtained. The washing tub motor is used to drive the washing tub to rotate. For example, the faster the speed of the washing tub motor, the faster the washing tub rotates, and the slower the speed of the washing tub motor, the slower the washing tub rotates. The first power indicates the power output of the motor during operation.

[0103] The operating mode of the washing machine is determined based on the first power. Optionally, when the first power is less than or equal to a preset power, the operating mode of the washing machine is determined to be a spin mode. The preset power can be the rated power of the washing machine or a power preset by the user. For example, when the first power is less than or equal to the preset power, it indicates that there is a lot of foam in the water in the washing tub, but the foam does not interfere with the spin speed of the washing machine during spin. In this case, the washing machine can enter the spin mode, and the washing tub rotates at high speed to drain water and foam from the clothes.

[0104] Optionally, when the first power is greater than a preset power, the washing machine is determined to be operating in a defoaming mode. For example, when the first power of the motor is greater than the preset power, it indicates that there is a lot of foam in the water in the washing tub, and the foam puts a heavy burden on the motor, so that the speed of the washing tub cannot reach the spin speed. In this case, the washing machine needs to reduce the foam in the water to increase the speed of the washing tub. Therefore, the washing machine enters the defoaming mode and defoams the foam by flushing with clean water.

[0105] In this feasible implementation method, when the foam value in the water is relatively high, the washing device determines the working mode of the washing device based on the first power output by the motor. If the motor can normally drive the washing tub to rotate at high speed, the washing device enters the dehydration mode, and the water and foam in the clothes are discharged through the dehydration mode. If the first power of the motor is greater than the preset power, the washing device cannot normally drive the washing tub to rotate at high speed, and the washing device enters the defoaming mode, and the foam is defoamed by flushing with clean water. This can improve the flexibility of the washing device control.

[0106] Next, combine Figure 3 , the process of determining the working mode of the washing equipment according to the foam value is explained.

[0107] Figure 3 This is a schematic diagram of a process for determining the working mode of a washing machine provided in an embodiment of the present application. Figure 3, including a washing device. The washing device includes a display panel, and the display panel of the washing device can display the working mode of the washing device. When the washing device obtains the foam value of the water in the washing tub, when the foam value is less than or equal to a preset threshold value, the working mode of the washing device is determined to be a dehydration mode, and the dehydration mode is displayed on the display panel of the washing device. When the foam value is greater than the preset threshold value, the washing device obtains a first power of the motor. If the first power is less than or equal to the preset power, the working mode of the washing device is determined to be a dehydration mode, and the dehydration mode is displayed on the display panel of the washing device; if the first power is greater than the preset power, the working mode of the washing device is determined to be a defoaming mode, and the defoaming mode is displayed on the display panel of the washing device.

[0108] S204: Control the washing equipment according to the working mode.

[0109] Optionally, when the working mode of the washing device is the defoaming mode, the washing device can work according to the washing parameters corresponding to the defoaming mode. Optionally, the washing parameters corresponding to the defoaming mode may include: motor stop, drain pump working time, water inlet valve working time, and the working sequence of the drain pump and the water inlet valve. For example, when the washing device enters the defoaming mode, the motor of the washing device stops, the drain pump stops after working for 2 minutes (draining the water with foam in the washing tub), when the drain pump stops, the water inlet valve opens (injecting clean water into the washing tub and flushing the foam in the clothes with clean water), the water inlet valve stops after working for 3 minutes, when the water inlet valve stops, the drain pump opens again (draining the water with foam in the washing tub again), the drain pump stops after working for 2 minutes, and when the washing device completes the above steps, the defoaming process of the washing device ends.

[0110] Optionally, when the working mode of the washing machine is the spin mode, the washing machine can operate according to the spin speed corresponding to the spin mode. For example, if the spin speed is 500 revolutions per minute, then when the working mode of the washing machine is the spin mode, the speed of the washing tub of the washing machine is 500 revolutions per minute.

[0111] Optionally, when the operating mode of the washing machine is the alarm mode, the washing machine may operate according to the alarm information corresponding to the alarm mode. For example, if the alarm information is to generate a buzzer prompt sound, then when the operating mode of the washing machine is the alarm mode, the washing machine generates a buzzer prompt sound.

[0112] The embodiment of the present application provides a control method for a washing device. At the end of the washing stage of the washing device, a first water level frequency of the washing device is obtained, and the foam value of the water in the washing tub is determined based on the first water level frequency. When the foam value is less than or equal to a preset threshold, the working mode of the washing device is determined to be a dehydration mode. When the foam value is greater than the preset threshold, a first power of the motor is obtained, and the working mode of the washing device is determined based on the first power. When the first power is greater than the preset power, the working mode of the washing device is determined to be a defoaming mode. In the above method, when the foam value is small, the foam will not affect the dehydration speed of the washing device, and the washing device can enter the dehydration mode, thereby reducing the power consumption of the washing device. When the foam value is large, if the first power is greater than the preset power, it means that the foam affects the dehydration speed of the washing device, and the washing device enters the defoaming mode, and the foam is defoamed by rinsing with clean water. The washing device can accurately determine the working mode of the washing device through the foam value, which not only improves the defoaming effect of the washing device, but also improves the flexibility of the defoaming control of the washing device.

[0113] exist Figure 2 On the basis of the embodiment shown, when the working mode of the washing device is determined to be the defoaming mode, the washing device can also determine the working mode of the next stage. Figure 4 , a method for determining the working mode of the washing equipment after the defoaming mode is explained.

[0114] Figure 4 This is a flow chart of a method for a washing machine to determine the next stage of operation mode provided in an embodiment of the present application. Figure 4 , the method comprising:

[0115] S401. When the washing equipment finishes defoaming, obtain a second water level frequency in the washing tub.

[0116] The second water level frequency is the water level frequency output by the water level sensor of the washing machine when the washing machine finishes defoaming. Optionally, when the operating mode of the washing machine is the defoaming mode, the washing machine operates according to the washing parameters corresponding to the defoaming mode, and the defoaming process of the washing machine ends when the defoaming process in the washing mode is completed.

[0117] Optionally, the washing device obtains the second water level frequency in the same manner as the washing device obtains the first water level frequency, which is not described in detail in this embodiment of the present application.

[0118] S402: Determine the next operating mode of the washing equipment according to the second water level frequency.

[0119] The next stage of operation mode of the washing machine is the operation mode of the washing machine after the defoaming mode ends. When determining the next stage of operation mode of the washing machine according to the second water level frequency, there are three situations as follows:

[0120] Case 1: the second water level frequency is greater than or equal to the second threshold.

[0121] When the second water level frequency is greater than or equal to the second threshold, the next operating mode of the washing machine is determined to be the spin mode. For example, at the end of the defoaming process of the washing machine, since the water level frequency is inversely proportional to the foam level, if the second water level frequency is greater than the second threshold, it indicates that the foam level in the water in the washing tub is low and the foam will not affect the spin speed of the washing machine. In this case, the next operating mode of the washing machine is the spin mode.

[0122] In this case, when the second water level frequency is greater than or equal to the second threshold, it means that the defoaming effect of the washing equipment is better when working in the defoaming mode. After the washing equipment defoams, there is less foam in the water in the washing tub, and the washing equipment can enter the dehydration mode, thereby improving the flexibility of the washing equipment control.

[0123] Case 2: the second water level frequency is greater than the first threshold, and the second water level frequency is less than the second threshold.

[0124] When the second water level frequency is greater than the first threshold and the second water level frequency is less than the second threshold, the operating mode of the washing machine in the next stage can be determined according to the following feasible implementation method: the number of defoaming times of the washing machine in the current washing process is obtained. Optionally, the number of defoaming times of the washing machine in the current washing process can be determined based on the number of times the washing machine enters the defoaming mode in the current washing process. For example, if the washing machine enters the defoaming mode three times in the current washing process, the number of defoaming times of the washing machine in the current washing process is three.

[0125] The next operating mode is determined based on the number of defoaming cycles. Optionally, when the number of defoaming cycles is less than or equal to a third threshold, the next operating mode is determined to be the defoaming mode. For example, when the second water level frequency is greater than the first threshold and the second water level frequency is less than the second threshold, indicating that the water still contains some foam, if the number of defoaming cycles of the washing machine during this washing process is small, the washing machine is controlled to enter the defoaming mode to continue defoaming the foam in the clothes.

[0126] Optionally, when the number of defoaming cycles exceeds a third threshold, the next operating mode is determined to be the spin mode. For example, when the second water level frequency is greater than the first threshold and less than the second threshold, indicating that the water still contains some foam, if the washing machine defoams a large number of times during this washing process, the washing machine is controlled to directly enter the spin mode to dehydrate the clothes.

[0127] In this case, when the second water level frequency is greater than the first threshold and the second water level frequency is less than the second threshold, if the washing machine has defoamed many times during this washing process, it means that the washing machine has already defoamed the clothes multiple times. At this time, although there is still a small amount of foam in the water, the foam will not affect the dehydration speed of the washing machine. Therefore, the washing machine can enter the dehydration mode to spin the clothes. If the washing machine has defoamed few times during this washing process, it means that the foam in the water can still affect the dehydration speed of the washing machine. Therefore, the washing machine can enter the defoaming mode and defoam the clothes again. This can improve the defoaming effect of the washing machine and increase the flexibility of the washing machine in controlling defoaming.

[0128] Next, combine Figure 5 , detailing the process of determining the next stage of operation mode of the washing equipment in this case.

[0129] Figure 5 This is a schematic diagram of a process for determining the next stage of operation mode of a washing machine provided in an embodiment of the present application. Figure 5 , including a washing machine. When the display panel of the washing machine shows that defoaming is finished, if the second water level frequency obtained by the washing machine is greater than the first threshold value, and the second water level frequency is less than the second threshold value, the number of defoaming times of the washing machine in this washing process is obtained. When the number of defoaming times is greater than the third threshold value, it is determined that the next operating mode of the washing machine after the defoaming mode is the dehydration mode, and the display panel of the washing machine displays the dehydration mode. When the number of defoaming times is less than or equal to the third threshold value, it is determined that the next operating mode of the washing machine after the defoaming mode is the defoaming mode, and the display panel of the washing machine displays the defoaming mode.

[0130] Optional, in Figure 5 In the illustrated embodiment, for ease of explanation, the display panel of the washing device displays the working mode. In actual application, the display panel of the washing device may or may not display the working mode.

[0131] Case 3: The second water level frequency is less than or equal to the first threshold.

[0132] When the second water level frequency is less than or equal to the first threshold, the washing machine is determined to be in alarm mode for the next stage of operation. For example, after the washing machine has performed a defoaming treatment on the clothes, if the second water level frequency is less than or equal to the first threshold, it indicates that the washing machine has not effectively reduced the foam in the clothes (due to a drainage pump malfunction) or that the amount of foam is excessive due to improper user operation (excessive use of detergent). In this case, the washing machine is controlled to enter alarm mode to notify the user that the washing machine has malfunctioned, making it unable to effectively eliminate foam.

[0133] In this case, after the washing machine performs a defoaming treatment on the clothes, if the second water level frequency is less than or equal to the first threshold value, it means that the foam value of the water in the washing tub is still high, and this defoaming treatment cannot effectively reduce the foam in the water. The washing machine enters the alarm mode to remind the user that the washing machine has a malfunction. In this way, it is possible to accurately determine whether the washing machine has a malfunction based on the second water level frequency, thereby improving the safety of the use of the washing machine and the flexibility of control.

[0134] S403: Control the washing equipment according to the working mode of the next stage.

[0135] It should be noted that the execution process of S403 can refer to the execution process of S204, and will not be described in detail here.

[0136] An embodiment of the present application provides a control method for a washing machine. When the washing machine finishes defoaming, a second water level frequency in the washing tub is obtained. Based on the second water level frequency, the operating mode of the washing machine in the next stage is determined, and the washing machine is controlled based on the operating mode in the next stage. In the above method, when the washing machine finishes defoaming, the washing machine can determine the effectiveness of the defoaming process based on the second water level frequency, and then determine whether the washing machine needs to continue defoaming the clothes in the next stage. This not only improves the defoaming effect of the washing machine, but also increases the flexibility of the defoaming control of the washing machine.

[0137] Based on any of the above embodiments, Figure 6 , the process of the control method of the above-mentioned washing equipment is explained.

[0138] Figure 6 This is a process diagram of a control method for a washing machine provided in an embodiment of the present application. Figure 6 The washing machine includes a washing device. At the end of a washing phase of the washing device, the washing device obtains a first water level frequency and determines a foam value of water in the washing tub according to the first water level frequency.

[0139] See Figure 6When the foam value is less than or equal to a preset threshold, the operating mode of the washing machine is determined to be the dehydration mode, the display panel of the washing machine displays the dehydration mode, and the washing machine operates according to the dehydration speed corresponding to the dehydration mode. When the foam value is greater than the preset threshold, the first power of the motor is obtained. When the first power is less than or equal to the preset power, the operating mode of the washing machine is determined to be the dehydration mode, the display panel of the washing machine displays the dehydration mode, and the washing machine operates according to the dehydration speed corresponding to the dehydration mode. When the first power is greater than the preset power, the operating mode of the washing machine is determined to be the defoaming mode, the display panel of the washing machine displays the defoaming mode, and the washing machine operates according to the washing parameters corresponding to the defoaming mode.

[0140] See Figure 6 After the washing machine finishes defoaming, a second water level frequency of the washing machine is obtained. When the second water level frequency is greater than or equal to a second threshold, the washing machine is determined to be in a spin mode for the next stage of operation. The display panel of the washing machine displays the spin mode, and the washing machine operates according to the spin speed corresponding to the spin mode. When the second water level frequency is less than or equal to the first threshold, the washing machine is determined to be in an alarm mode for the next stage of operation. The display panel of the washing machine displays the alarm mode, and the washing machine operates according to the alarm information corresponding to the alarm mode.

[0141] See Figure 6 When the second water level frequency of the washing device is greater than the first threshold but less than the second threshold, the number of defoaming operations of the washing device during the current washing process is obtained. When the number of defoaming operations is greater than a third threshold, the next operating mode of the washing device is determined to be the dehydration mode. The display panel of the washing device displays the dehydration mode, and the washing device operates according to the dehydration speed corresponding to the dehydration mode. When the number of defoaming operations is less than or equal to the third threshold, the next operating mode of the washing device is determined to be the defoaming mode. The display panel of the washing device displays the defoaming mode, and the washing device operates according to the washing parameters corresponding to the defoaming mode. The washing device can accurately determine the operating mode of the washing device based on the foam value of the water in the washing tub. When the defoaming operation of the washing device is completed, the defoaming effect of the washing device can be further determined, and the next operating mode of the washing device after the defoaming operation is completed can be determined. This can reduce the power consumption of the washing device and improve the washing effect of the washing device while increasing the flexibility of the defoaming control of the washing device.
