Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a washing machine flatness detection device, a washing machine, and a washing machine control method. Background Technology

[0002] Washing machines are common household appliances that provide convenience for users. During initial installation, washing machines are leveled to ensure they are placed as flat as possible, reducing vibrations during later operation.

[0003] In existing technologies, leveling operations mostly involve manually adjusting the height of the washing machine's support feet, judging the flatness of the machine by visual inspection, which can only provide a rough leveling result. Moreover, even if the washing machine is leveled during installation, it may still tilt after a period of use, but users usually do not notice it. Over time, this will cause the washing machine to vibrate more during operation, increase wear and tear on parts, affect its lifespan, and increase operating noise, thus impacting the user experience.

[0004] Therefore, there is an urgent need for a washing machine flatness detection device, a washing machine, and a washing machine control method to solve the above problems. Summary of the Invention

[0005] Based on the above problems, the purpose of this invention is to provide a washing machine flatness detection device, a washing machine, and a washing machine control method, which can detect the flatness of the washing machine and improve the operational stability and reliability of the washing machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] In a first aspect, a washing machine flatness detection device is provided, comprising:

[0008] A liquid pipeline extends at least partially along the height of the washing machine, the liquid pipeline stores liquid, and the liquid pipeline is provided on at least two opposite sides of the washing machine, with the two opposite liquid pipelines connected.

[0014] The display component includes a display screen that is communicatively connected to the detection component, and the display screen is capable of displaying the detection value of the detection component.

[0015] As an optional embodiment of the washing machine flatness detection device of the present invention, the detection component includes a pressure gauge, which is disposed at the water inlet end of the liquid pipeline;

[0016] And / or, the washing machine includes a support foot with adjustable support height, and the washing machine flatness detection device further includes a drive mechanism, the output end of which is connected to the support foot for adjusting the support height of the support foot.

[0017] Secondly, a washing machine is provided, including a cabinet and a washing machine flatness detection device as described above, wherein the bottom of the cabinet is provided with support feet with adjustable support height, and the washing machine flatness detection device is disposed in the cabinet.

[0018] Thirdly, a washing machine control method is provided, applied to the washing machine described above, wherein the washing machine has a clothes handling program and a flatness detection program; the washing machine control method includes the following steps:

[0019] Before executing the garment processing procedure, start the smoothness detection procedure;

[0020] The flatness of the washing machine is determined according to the flatness detection procedure.

[0021] Determine whether the flatness of the washing machine meets the preset conditions. If yes, execute the clothing processing program; otherwise, control the washing machine to issue a prompt message.

[0022] As an optional embodiment of the washing machine control method of the present invention, the flatness detection procedure includes the following steps:

[0023] Obtain the detection values ​​of the detection components corresponding to the two connected liquid pipelines;

[0024] Calculate the difference in detection values ​​of the detection components corresponding to the two connected liquid pipelines;

[0025] Determine the threshold range to which the difference belongs, and determine the flatness of the washing machine based on the threshold range to which the difference belongs.

[0026] As an optional solution to the washing machine control method of the present invention, when the difference is within the first threshold range, the current flatness of the washing machine satisfies the preset condition;

[0027] When the difference is within the second threshold range, the washing machine is controlled to complete the current clothing processing program and issue a first prompt message, where the value of the second threshold range is greater than the value of the first threshold range.

[0028] When the difference is within the third threshold range, the washing machine is controlled to stop the current clothing processing program and a second prompt message is issued, wherein the value of the third threshold range is greater than the value of the second threshold range.

[0029] As an optional embodiment of the washing machine control method of the present invention, in the step of "obtaining the detection values ​​of the detection components corresponding to the two connected liquid pipelines":

[0030] When the detection value of the detection component is less than or equal to the first set value, the liquid pipeline is controlled to receive liquid;

[0031] When the detection value of the detection component of at least one of the two connected liquid pipelines reaches the second set value, the liquid pipeline is controlled to stop liquid inflow, and the second set value is greater than the first set value;

[0032] When the detection value of the detection component is less than or equal to the minimum threshold, the washing machine is controlled to issue a third prompt message, wherein the minimum threshold is less than the first set value.

[0033] As an optional solution to the washing machine control method of the present invention, the washing machine flatness detection device further includes a drive mechanism, the output end of which is connected to the support foot for adjusting the support height of the support foot;

[0034] The washing machine control method further includes the following steps:

[0035] The tilt direction of the washing machine is determined based on the flatness of the washing machine;

[0036] Determine the position of the support foot whose support height needs to be adjusted based on the tilt direction;

[0037] The support height of the support foot at the corresponding position is adjusted by the drive mechanism so that the flatness of the washing machine meets the preset condition.

[0038] The beneficial effects of this invention are as follows:

[0039] The washing machine flatness detection device provided by this invention utilizes two interconnected liquid pipes on opposite sides of the washing machine, forming a communicating vessel. Therefore, when the washing machine is placed unevenly on a supporting foundation (such as the ground or countertop) and tilts, to maintain the liquid levels in the two interconnected liquid pipes, the liquid in the higher-lying pipe will flow to the lower-lying pipe. This change in the amount of liquid in the two pipes causes a change in the detection values ​​of the corresponding two detection components. Specifically, less liquid in the higher-lying pipe reduces the liquid pressure on the corresponding detection component, resulting in a smaller detection value; conversely, more liquid in the lower-lying pipe increases the liquid pressure on the corresponding detection component, resulting in a larger detection value. By comparing the detection values ​​of the detection components corresponding to the two interconnected liquid pipes, it can be determined whether the washing machine is level. The greater the difference in the detection values ​​between the two components, the greater the tilt of the washing machine. This washing machine flatness detection device can detect the flatness of the washing machine in real time, preventing the washing machine from running the clothes processing program when it is significantly tilted, thereby preventing excessive vibration during operation, reducing noise, and extending the service life of the washing machine.

[0040] The washing machine and its control method provided by this invention initiate a flatness detection program before executing the clothes handling program to determine the flatness of the washing machine. The clothes handling program is only executed when the flatness of the washing machine meets preset conditions. If the flatness does not meet the preset conditions, the washing machine will issue a prompt message to promptly remind the user to adjust the flatness of the washing machine. This prevents excessive vibration during the clothes handling program, reduces noise, minimizes wear on components, improves the operational stability of the washing machine, extends its service life, and enhances the user experience.

[0059] Example 1

[0060] like Figures 1 to 5 As shown, this embodiment provides a washing machine flatness detection device, which can detect the flatness of the washing machine in real time, thereby improving the operational stability and reliability of the washing machine. The washing machine flatness detection device includes a liquid pipeline 1 and a detection component 2.

[0061] Among them, see Figure 1 , Figure 2 and Figure 3 The liquid pipe 1 extends at least partially along the height of the washing machine. The liquid pipe 1 stores liquid, and liquid pipes 1 are provided on at least two opposite sides of the washing machine, with the two opposite liquid pipes 1 connected. A detection component 2 is provided for each liquid pipe 1, and the detection component 2 is used to detect the pressure value of the liquid in the corresponding liquid pipe 1.

[0062] The washing machine flatness detection device provided in this embodiment utilizes a system where two liquid pipes 1 on opposite sides of the washing machine are connected, forming a communicating vessel. Therefore, when the washing machine is placed unevenly on a supporting foundation (such as the ground or a countertop) and tilts, to maintain a level liquid level in the two connected liquid pipes 1, the liquid in the higher-lying liquid pipe 1 will flow to the lower-lying liquid pipe 1. This change in the amount of liquid in the two liquid pipes 1 causes a change in the detection values ​​of the corresponding two detection components 2. Specifically, if there is less liquid in the higher-lying liquid pipe 1, the liquid pressure on the corresponding detection component 2 decreases, resulting in a smaller detection value; conversely, if there is more liquid in the lower-lying liquid pipe 1, the liquid pressure on the corresponding detection component 2 increases, resulting in a larger detection value. By comparing the detection values ​​of the detection components 2 corresponding to the two connected liquid pipes 1, it can be determined whether the washing machine is level. The greater the difference in the detection values ​​of the two detection components 2, the greater the tilt of the washing machine.

[0063] This washing machine flatness detection device can detect the flatness of the washing machine in real time and promptly remind users to adjust the flatness of the washing machine. This prevents the washing machine from running the clothes processing program when it is significantly tilted, thereby preventing excessive vibration during operation, reducing noise, and extending the service life of the washing machine.

[0064] Optionally, see Figure 1 , Figure 2 and Figure 3 There are two liquid lines 1, which are arranged diagonally and connected within the washing machine's housing 10. This arrangement ensures that the liquid volume in both liquid lines 1 changes regardless of whether the washing machine is tilted forward or backward or left or right, thus altering the detection value of the corresponding detection component 2 and detecting the tilt, thereby improving the accuracy of the washing machine's flatness detection.

[0065] Reference Figure 1 In the orientation of the washing machine, one liquid pipe 1 is located at the right rear corner, and the other liquid pipe 1 is located at the left front corner. Of course, the two liquid pipes 1 mentioned above can also be located at the left rear corner and the right front corner of the washing machine.

[0066] In some other embodiments, the two liquid pipes 1 can also be arranged front to back or side to side. Alternatively, two sets of liquid pipes 1 can be set, each set including two connected liquid pipes 1. In one set, the two liquid pipes 1 are arranged front to back, and in the other set, the two liquid pipes 1 are arranged side to side. In this way, the skewness in the front-back direction and the left-right direction of the washing machine can also be detected.

[0067] See Figure 1 , Figure 2 and Figure 3 The washing machine includes a drain assembly 20, and the inlet of the liquid pipe 1 is selectively connected to the outlet of the drain assembly 20. That is, the liquid stored in the liquid pipe 1 is water. When the flatness detection program is first started, or when water needs to be added to the liquid pipe 1, the washing machine is controlled to fill with water, while simultaneously the drain outlet of the drain assembly 20 is closed and the inlet of the liquid pipe 1 is opened, allowing water to enter the liquid pipe 1 through the drain assembly 20. When the water level in the liquid pipe 1 meets the requirements, the washing machine is controlled to stop filling with water, while simultaneously the drain outlet of the drain assembly 20 is opened and the inlet of the liquid pipe 1 is closed, allowing excess water to be discharged from the washing machine through the drain outlet of the drain assembly 20.

[0068] Optionally, the washing machine is a top-drain type, and the drain assembly 20 includes a drain pump. The inlet end of the liquid pipeline 1 is selectively connected to the outlet end of the drain pump. Further, a valve can be installed at the inlet end of the liquid pipeline 1 to control the connection and disconnection between the liquid pipeline 1 and the outlet end of the drain pump.

[0069] Of course, in other embodiments, the liquid in the liquid pipeline 1 can also be a liquid medium other than water, as long as it meets the detection requirements.

[0070] Optionally, see Figure 1 The liquid pipeline 1 includes a first pipe section 11 and a second pipe section 12 connected at an angle. The end of the first pipe section 11 away from the second pipe section 12 is connected to the outlet of the drain pump. The second pipe section 12 extends along the placement height of the washing machine. The detection component 2 is disposed on the first pipe section 11, or the detection component 2 can also be disposed on the second pipe section 12 close to the first pipe section 11, so that the detection component 2 can accurately detect the pressure value of the liquid in the corresponding liquid pipeline 1 and accurately reflect the amount of liquid in the liquid pipeline 1.

[0071] In some embodiments, such as a bottom-drain washing machine, the washing machine includes a water inlet assembly, and the water inlet end of the liquid line 1 is selectively connected to the water outlet end of the water inlet assembly. When water needs to be supplied to the liquid line 1, the washing machine is controlled to supply water, and the liquid line 1 is connected to the water outlet end of the water inlet assembly. When the water level in the liquid line 1 meets the requirements, the washing machine is controlled to stop supplying water, and the liquid line 1 is disconnected from the water outlet end of the water inlet assembly.

[0072] Optionally, the washing machine flatness detection device also includes a display component 3, which displays the amount of liquid in the corresponding liquid pipe 1, so that users can view it intuitively and take appropriate measures in a timely manner.

[0073] In one alternative implementation, see [reference] Figure 1 and Figure 4The display component 3 includes a tube 31 connected to the liquid pipeline 1. At least a portion of the tube 31 is transparent, and a scale line 311 is provided in the transparent area of ​​the tube 31 to indicate the liquid level in the liquid pipeline 1. That is, the liquid in the liquid pipeline 1 enters the tube 31 of the display component 3, and the liquid level in the tube 31 is the liquid level in the liquid pipeline 1. When the washing machine is not tilted, the amount of liquid in the two connected liquid pipelines 1 is the same; therefore, the liquid level in the corresponding two tubes 31 is consistent, and the scale line 311 shows the same value. When the washing machine is tilted, the liquid level in the higher-lying liquid pipeline 1 decreases, and the value of the scale line 311 corresponding to that liquid level on the tube 31 decreases; conversely, the liquid level in the lower-lying liquid pipeline 1 rises, and the value of the scale line 311 corresponding to that liquid level increases. The tilt direction of the washing machine can be determined by observing the value of the scale line 311 corresponding to the liquid level on the tube 31, allowing the user to adjust the support height of the support foot 30 at the corresponding position of the washing machine according to the tilt direction. For example, the support foot 30 includes an adjusting nut, which the user can turn to adjust the support height of the support foot 30.

[0074] In this embodiment, see Figure 1 and Figure 4 The display surface (the surface with scale lines 311) of the tube body 31 is exposed outside the washing machine cabinet 10. The display surface may be slightly protruding from the outer surface of the cabinet 10, or the display surface may be flush with the outer surface of the cabinet 10, so that users can easily check the liquid level in the corresponding liquid pipe 1 to determine the tilt direction of the washing machine.

[0075] For example, see Figure 4 Each long graduation line 311 represents 1 graduation, corresponding to a liquid level of 1mm. Each short graduation line 311 represents 0.5 graduations, corresponding to a liquid level of 0.5mm. When the liquid level difference between the two connected liquid pipes 1 is one graduation, it indicates that the washing machine is tilted by 1mm.

[0076] In other embodiments, the liquid level height value corresponding to each scale line 311 can be calibrated according to the actual situation, and is not limited to the specific values ​​listed in this embodiment.

[0077] See Figure 5 The washing machine flatness detection device also includes an alarm module 4 that is communicatively connected to the detection component 2. (See reference...) Figure 4The display component 3 has a tube body 31 with a first scale 3110, a second scale 3120, and a third scale 3130. The first scale 3110 corresponds to the highest liquid level in the liquid pipeline 1, the second scale 3120 corresponds to the threshold liquid level when the liquid pipeline 1 needs to be replenished, and the third scale 3130 corresponds to the threshold liquid level when the liquid pipeline 1 has a fault (e.g., leakage). The detection component 2 has a first detection value, a second detection value, and a third detection value that correspond one-to-one with the first scale 3110, the second scale 3120, and the third scale 3130.

[0078] When liquid is introduced into liquid line 1, if the detection value of the detection component 2 reaches the first detection value, it indicates that the liquid level in liquid line 1 has reached the first mark 3110. At this time, the liquid line 1 is stopped from introducing liquid to prevent excessive liquid from entering. When the detection value of the detection component 2 reaches the second detection value, it indicates that the liquid in liquid line 1 is insufficient (the liquid level in liquid line 1 reaches the second mark 3120). At this time, the liquid line 1 is introduced to replenish liquid in a timely manner. When the detection value of the detection component 2 reaches the third detection value, it indicates that there may be a leakage problem in liquid line 1 (the liquid level in liquid line 1 reaches the third mark 3130). The alarm module 4 is activated to alert the user to check and take appropriate measures. By observing the scale on the pipe body 31, the location of the leakage problem in liquid line 1 can be determined.

[0079] For example, the alarm module 4 can be a sound alarm or an indicator light, etc.

[0080] In another alternative implementation, see Figure 5 The display component 3 may also include a display screen 32 that is communicatively connected to the detection component 2. The display screen 32 can display the detection value of the detection component 2. That is, the detection value of the detection component 2 is directly displayed on the display screen 32, and the user can know the amount of liquid in the corresponding liquid pipe 1 by viewing the data on the display screen 32, and thus determine the tilt direction of the washing machine. For example, the display screen 32 may be the display panel of the washing machine.

[0081] Optionally, the detection component 2 includes a pressure gauge, which is disposed at the water inlet end of the liquid pipeline 1. Specifically, in this embodiment... Figure 1 In the process, the pressure gauge is located on the first section 11 of the liquid pipeline 1. When the liquid level in the second section 12 changes, the pressure value detected by the pressure gauge changes.

[0082] In other embodiments, a pressure gauge shut-off valve can also be installed on the liquid pipeline 1, and the detection component 2 is a pressure gauge of the pressure gauge shut-off valve. The pressure gauge shut-off valve can control the opening and closing of the water inlet end of the liquid pipeline 1.

[0083] See Figure 1 , Figure 2 and Figure 3 The washing machine includes height-adjustable support feet 30. The washing machine flatness detection device also includes a drive mechanism (not shown). The output end of the drive mechanism is connected to the support feet 30 for adjusting their support height. When the washing machine's tilt exceeds the allowable range, the position of the support feet 30 requiring height adjustment is determined based on the tilt direction. The drive mechanism then adjusts the support height of the corresponding support feet 30 until the washing machine is level. In other words, when the washing machine is detected to be tilted, it can automatically level itself, improving leveling efficiency and saving time and effort.

[0084] Optionally, the support foot 30 includes a support base and a lifting rod disposed on the support base. The lifting rod is connected to the bottom of the washing machine body 10. The drive mechanism can be a screw and nut mechanism. The movable end of the lifting rod is connected to the nut seat of the screw and nut mechanism to drive the lifting rod to rise and fall, thereby adjusting the support height of the support foot 30.

[0085] Example 2

[0086] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a washing machine, including a housing 10 and a washing machine flatness detection device as described in Embodiment 1 above. The bottom of the housing 10 is provided with height-adjustable support feet 30, and the washing machine flatness detection device is disposed on the housing 10. The washing machine flatness detection device can detect the flatness of the washing machine. Only when the flatness of the washing machine meets preset conditions will the clothes processing program be executed. This prevents the washing machine from running the clothes processing program when it is significantly tilted, avoiding excessive vibration, reducing noise, reducing wear on parts, improving the operational stability of the washing machine, and extending its service life.

[0087] Optionally, see Figure 1 The washing machine body 10 is equipped with a knob 101, which can be turned to select different clothing processing programs.

[0088] See Figure 5 The washing machine also includes a control module 5, which is connected to the detection component 2 and the drive mechanism. When the washing machine is detected to be tilted, the control module 5 controls the drive mechanism to drive the support foot 30 at the corresponding position to rise and fall until the washing machine is leveled.

[0089] Example 3

[0090] like Figure 6 As shown, this embodiment provides a washing machine control method, applied to the washing machine described in Embodiment 2 above, wherein the washing machine has a clothes handling program and a flatness detection program.

[0091] like Figure 6 As shown, the washing machine control method includes the following steps:

[0092] S1. Before executing the garment processing procedure, start the flatness detection procedure;

[0093] S2. Determine the flatness of the washing machine according to the flatness testing procedure;

[0094] S3. Determine whether the flatness of the washing machine meets the preset conditions. If yes, execute the clothes processing program; otherwise, control the washing machine to issue a prompt message.

[0095] This washing machine control method determines the flatness of the washing machine by executing a flatness detection program before starting the clothes handling program. This ensures that the clothes handling program is only executed when the flatness meets preset conditions, preventing excessive vibration, reducing noise, and extending the washing machine's lifespan. Furthermore, if the flatness of the washing machine does not meet the preset conditions, it will issue a prompt message to promptly remind the user to adjust the flatness, ensuring the washing machine's operational stability.

[0096] Specifically, such as Figure 7 As shown, in steps S1 and S2, the flatness detection procedure includes the following steps:

[0097] R1. Obtain the detection values ​​of the detection components 2 corresponding to the two connected liquid pipelines 1;

[0098] R2. Calculate the difference in detection values ​​of the detection components 2 corresponding to the two connected liquid pipelines 1;

[0099] R3. Determine the threshold range to which the difference belongs, and determine the flatness of the washing machine based on the threshold range to which the difference belongs.

[0100] The smaller the difference between the detection values ​​of the two detection components 2, the better the flatness of the washing machine placement; the larger the difference between the detection values ​​of the two detection components 2, the greater the tilt of the washing machine, which needs to be leveled in time.

[0101] like Figure 8 As shown, steps S2 and S3, the steps for determining whether the flatness of the washing machine meets the preset conditions, include:

[0102] When the difference is within the first threshold range, the current flatness of the washing machine meets the preset conditions. That is, the tilt of the washing machine is within the allowable range, and no leveling operation is required.

[0103] When the difference is within the second threshold range, the washing machine will issue a first prompt message after completing the current clothes processing program. The value in the second threshold range is greater than the value in the first threshold range. This indicates that the washing machine's tilt is small and will not cause significant damage. The user will be reminded to level the machine after the current clothes processing program is completed, without affecting the normal execution of the current program.

[0104] When the difference is within the third threshold range, the washing machine stops the current clothes processing program and issues a second prompt message: the value in the third threshold range is greater than the value in the second threshold range. This indicates that the washing machine is tilted too much; continuing to run it will cause significant vibration and damage to parts. The user is reminded to level the machine before continuing the clothes processing program to prevent malfunctions and extend its lifespan.

[0105] Optionally, the detection values ​​of the detection component 2 can be calibrated one-to-one with the scale values ​​on the tube 31 of the display component 3. When the difference between the detection values ​​of the two detection components 2 is within a first threshold range, the difference in liquid level height in the two tubes 31 is less than or equal to one scale mark. When the difference between the two detection components 2 is within a second threshold range, the difference in liquid level height in the two tubes 31 is greater than one scale mark and less than four scale marks. When the difference between the two detection components 2 is within a third threshold range, the difference in liquid level height in the two tubes 31 is greater than or equal to four scale marks.

[0106] It should be noted that the first threshold range, the second threshold range, and the third threshold range may vary depending on the model. In specific design, the values ​​of the first threshold range, the second threshold range, and the third threshold range can be determined based on actual model testing, and are not limited to the ranges listed in this embodiment.

[0107] Optionally, the washing machine flatness detection device includes an alarm module 4 communicatively connected to the detection component 2. The alarm module 4 is used to issue a first prompt message and a second prompt message. For example, the alarm module 4 is an audible alarm, and the first and second prompt messages are different sounds. Alternatively, the alarm module 4 is a voice announcer, with the first prompt message being a voice indicating "slight tilt" and the second prompt message being a voice indicating "severe tilt".

[0108] Optionally, in the step of "obtaining the detection values ​​of the detection components 2 corresponding to the two connected liquid pipelines 1":

[0109] When the detection value of the detection component 2 is less than or equal to the first set value, the liquid pipeline 1 is controlled to enter the liquid.

[0110] When the detection value of the detection component 2 of at least one of the two connected liquid pipelines 1 reaches the second set value, the liquid pipeline 1 is controlled to stop liquid inflow, and the second set value is greater than the first set value.

[0111] When the detection value of the detection component 2 is less than or equal to the minimum threshold, the washing machine is controlled to issue a third prompt message, indicating that the minimum threshold is less than the first set value.

[0112] In this embodiment, the first set value corresponds to Figure 4 The second scale 3120 on the central tube 31 indicates that liquid needs to be added to the liquid line 1 when the detection value of the detection component 2 is less than or equal to the first set value, to ensure that there is enough liquid in the liquid line 1 to detect the flatness of the washing machine. The second set value corresponds to... Figure 4 The first scale 3110 on the middle tube 31 indicates that the liquid volume in the liquid pipeline 1 meets the requirements when the detection value of the detection component 2 reaches the second set value. This controls the liquid pipeline 1 to stop supplying liquid and prevent overflow. The minimum threshold corresponds to... Figure 4 The third scale 3130 on the central tube 31 indicates a potential leak in the liquid pipeline 1 when the detection value of the detection component 2 is less than or equal to the minimum threshold. The alarm module 4 then issues a third warning message to promptly remind the user to check and take appropriate measures. The third warning message can be an audio message different from the first and second warning messages.

[0113] Example 4

[0114] This embodiment provides a washing machine control method, which is a further improvement on Embodiment 3. The main difference is:

[0115] The washing machine flatness detection device also includes a drive mechanism, the output end of which is connected to the support foot 30 to adjust the support height of the support foot 30.

[0116] like Figure 9 As shown, the washing machine control method also includes the following steps:

[0117] S4. Determine the tilt direction of the washing machine based on its flatness;

[0118] S5. Determine the position of the support foot 30 whose support height needs to be adjusted according to the tilt direction;

[0119] S6. Adjust the support height of the support foot 30 at the corresponding position through the drive mechanism so that the flatness of the washing machine meets the preset conditions.

[0120] Specifically, refer to Figure 1If the detection value of the right-side detection component 2 is larger, the washing machine tilts to the right, controlling the drive mechanism to raise the right-side support leg 30, or controlling the drive mechanism to lower the left-side support leg 30. During the adjustment of the support leg 30's support height, the detection component 2 monitors the pressure value of the liquid in the corresponding liquid pipe 1 in real time. When the difference between the detection values ​​of the detection components 2 corresponding to the two connected liquid pipes 1 decreases to within the first threshold range, it indicates that the washing machine has completed leveling, and the drive mechanism can stop operating.

[0121] This washing machine control method can automatically level the washing machine by adjusting the support height of the support feet 30 according to the direction of the tilt of the washing machine through the drive mechanism when the washing machine is detected to tilt. The leveling efficiency is high and it saves time and effort.
