[0035] In the embodiments of the present disclosure, smart home appliances refer to home appliances that are formed by introducing microprocessors, sensor technology, and network communication technology into home appliances. They have the characteristics of intelligent control, intelligent perception, and intelligent application. The operation process of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet, and electronic chips. For example, smart home appliances can be connected to electronic devices to enable users to remotely control and manage the smart home appliances.

[0036] In the disclosed embodiments, the terminal device refers to an electronic device with a wireless connection function.

Mobile devices may include, for example, mobile phones, smart home devices, wearable devices, smart mobile devices, virtual reality devices, etc., or any combination thereof, wherein wearable devices include, for example: smart watches, smart bracelets, pedometers, etc.

[0037] At present, the structure of smart home appliances is usually provided with control keys for user operation. The specific structure of the control keys includes buttons, knobs or touch keys. In order to expand the functions of the control keys, smart washing machines are usually provided with knobs. By turning the knobs, users can realize different control functions, which can make the washing machine perform corresponding functions.

[0038] Related art discloses a knob, including a knob body and an encoder. The encoder is controlled to achieve the gear adjustment of the rotating body.

[0039] The knobs used in the related art have different gears that differ only in position. When a user operates the knob body at different gears, the feedback received is basically the same, and the user experience is poor.

[0040] The embodiment of the present disclosure provides a washing machine, comprising a washing machine body and a knob. The knob is mounted on the washing machine body. The knob comprises a knob body and a brushless DC motor. The brushless DC motor is embedded in the knob body and is configured to be controllably rotated clockwise or counterclockwise in the knob body.

[0041] Based on the above washing machine, combined Figure 1 As shown, the embodiment of the present disclosure provides a control method for a washing machine knob, comprising:

[0042] S01, the knob determines a target damping value and a target rotation angle of the brushless DC motor in response to a control instruction, and the control instruction is used to instruct the brushless DC motor to rotate.

[0043] S02, the knob obtains the current position of the brushless DC motor.

[0044] S03, the knob determines the control voltage of the brushless DC motor according to the current position and the target rotation angle.

[0045] S04, the knob controls the rotation of the brushless DC motor using the control voltage, so that the brushless DC motor rotates at a target rotation angle with a target damping value.

[0046] The control method for a washing machine knob provided by the embodiment of the present disclosure is adopted. The knob of the embodiment of the present disclosure responds to the control instruction to determine the target damping value and the target rotation angle of the brushless DC motor. Then the current position of the brushless DC motor is obtained, and the control voltage of the brushless DC motor is determined according to the current position and the target rotation angle. Finally, the brushless motor selection is controlled by the control voltage, so that the brushless DC motor rotates the target selection angle with the target damping value. In this way, when the brushless DC motor rotates from the current position to the target rotation angle, the target damping value can be used to provide the user with simulated force feedback, so that the user can obtain a different operating experience when operating the knob.

[0047] Optionally, combined Figure 2 As shown, the control instruction includes a target gear position. The knob determines the target damping value and the target rotation angle of the brushless DC motor in response to the control instruction, including:

[0048] S11, the knob determines a target rotation angle corresponding to a target gear position according to a correspondence between the gear position and the rotation angle.

[0049] In this step, the control instruction may include a target gear of the laundry parameter, and different types of laundry parameters correspond to different gears. As an example, the control instruction includes a target gear of 20L for the water level. The gears corresponding to water levels 10L, 20L, 30L, and 40L are first gear, second gear, third gear, and fourth gear, respectively. As another example, the control instruction includes a target gear v0 for the laundry speed. The gears corresponding to gears v0, v1, v2, v3, and v4 are first gear, second gear, third gear, fourth gear, and fifth gear, respectively.

[0050] In addition, the correspondence between the gear position and the rotation angle can be stored in a functional relationship or in an information table. The specific implementation method of the correspondence between the gear position selection angle is not specifically limited in the embodiment of the present disclosure.

[0051] S12, the knob determines a target damping value corresponding to the target rotation angle according to the corresponding relationship between the rotation angle and the damping value.

[0052] In this way, the disclosed embodiment can determine the target rotation angle corresponding to the target gear according to the correspondence between the gear and the rotation angle, and then determine the target damping value corresponding to the target rotation angle according to the correspondence between the rotation angle and the damping value. In this way, when the target gear carried by the control instruction is different, the target damping value fed back to the user by the knob is different, thereby outputting differentiated damping values ​​to the user, allowing the user to feel significantly different simulated force feedback, which is conducive to improving the user's operating experience.

[0053] Optionally, the gear position is arranged from small to large steps along the clockwise direction, and the stepped gear position is positively correlated with the rotation angle. The damping value is arranged from strong to weak along the counterclockwise direction, and the damping value is positively correlated with the rotation angle.

[0054] In this way, since the gear positions are set from small to large steps in the clockwise direction, and the damping value is set from strong to weak in the counterclockwise direction, the brushless DC motor can make the user feel obvious damping when it rotates from the current position to the target rotation angle, which is conducive to giving the user more obvious simulated force feedback and improving the user's operating experience.

[0055] It should be noted that the gear position can also be set in large and small steps in the counterclockwise direction, and the stepped gear position is positively correlated with the rotation angle. It can be understood that the gear position is set in small and large steps in the clockwise direction, which is more in line with the user's operating habits. Therefore, the direction in which the gear position is set in large steps can be determined according to the user's operating habits.

[0056] In a specific embodiment, the gears corresponding to the water levels 10L, 20L, 30L, 40L and 50L are respectively the first gear, the second gear, the third gear, the fourth gear and the fifth gear. The rotation angles corresponding to the first gear, the second gear, the third gear, the fourth gear and the fifth gear are 60 degrees, 120 degrees, 180 degrees, 240 degrees and 300 degrees respectively. It should be noted that the angle difference between the rotation angles corresponding to adjacent gears is equal. And the larger the rotation angle, the greater the damping value. Among them, when the knob is rotated to a specific angle, the user will feel a significant damping feeling, that is, the Duan damping is realized. Among them, the specific angle can be consistent with the above-mentioned rotation angle, or it can be an angle deviation added on the basis of the specific angle. The angle deviation can be the product of the angle difference and the weight coefficient. The weight coefficient is greater than 0 and less than or equal to one-half. Preferably, the weight coefficient is equal to one-half.

[0057] In another specific embodiment, the washing speed gears are respectively 1st gear, 2nd gear, 3rd gear, 4th gear and 5th gear. 1st gear, 2nd gear, 3rd gear and 4th gear. The rotation angles corresponding to 1st gear, 2nd gear, 3rd gear and 4th gear are 45 degrees, 90 degrees, 135 degrees and 180 degrees respectively. It should be noted that the angle difference between the rotation angles corresponding to adjacent gears is equal.

[0058] Optionally, combined Figure 3 As shown, when the target gear position of the knob is between adjacent gear positions, the target rotation angle corresponding to the target gear position is determined according to the corresponding relationship between the gear position and the rotation angle, including:

[0059] S21, the knob is rotated counterclockwise to obtain an alternative gear position, the alternative gear position is adjacent to the target gear position and the alternative gear position is smaller than the target gear position.

[0060] S22, the knob selects an alternative gear as a new target gear to determine a target rotation angle corresponding to the new target gear.

[0061] In this way, when the gears are arranged in a stepped manner, when the user selects the target gear, there is a situation where the selected target gear does not match the gear actually set by the knob. At this time, it is reflected on the knob, specifically that the target gear is located between adjacent gears. In this case, the embodiment of the present disclosure selects a gear that is adjacent to the target gear and smaller than the target gear in a counterclockwise direction as an alternative gear, and uses it as a new target gear. The new target gear selected in the above manner has a smaller gear deviation from the target gear actually selected by the user, and can also enable the user to feel an obvious sense of damping, which is beneficial to improving the user's operating experience when operating the knob.

[0062] Optionally, the knob determines the control voltage of the brushless DC motor according to the current position and the target rotation angle, including:

[0063] The knob determines the PWM (Pulse Width Modulation) control voltage corresponding to the current position and the target selection angle according to the corresponding relationship between the position and rotation angle and the voltage of the brushless DC motor.

[0064] In this way, the embodiment of the present disclosure can uniquely determine the PWM control voltage according to the corresponding relationship between the position and rotation angle and the voltage of the brushless DC motor, thereby realizing the control and regulation of the input voltage of the brushless DC motor.

[0065] Optionally, the correspondence between the position and rotation angle and the voltage of the brushless DC motor can be stored in a functional relationship or in an information table. The specific implementation of the correspondence between the position and rotation angle and the voltage of the brushless DC motor is not specifically limited in the embodiment of the present disclosure.

[0066] Combination Figure 4 As shown, the embodiment of the present disclosure provides another control method for a washing machine knob, comprising:

[0067] S31, the knob pushes a function list in response to the power-on instruction, and the function list includes different types of function options, including water level options, temperature options, and washing speed options.

[0068] S32, the knob displays a parameter adjustment interface in response to a selection instruction, the selection instruction is used to trigger the target function option, and the parameter adjustment interface represents an interface corresponding to the target function option.

[0069] S33, the knob determines the target damping value and the target rotation angle of the brushless DC motor in response to the control instruction, and the control instruction is used to instruct the brushless DC motor to rotate.

[0070] S34, the knob obtains the current position of the brushless DC motor.

[0071] S35, the knob determines the control voltage of the brushless DC motor according to the current position and the target rotation angle.

[0072] S36, the knob controls the rotation of the brushless DC motor using the control voltage, so that the brushless DC motor rotates at a target rotation angle with a target damping value.

[0073] The control method for the knob of a washing machine provided by the embodiment of the present disclosure is adopted. The embodiment of the present disclosure responds to the power-on instruction and pushes a function list for the user to select functions from different types of function options in the function list. Then, in response to the selection instruction, an interface corresponding to the target function option is displayed. Based on the above interface, the user sends a control instruction to instruct the brushless DC motor to rotate. Correspondingly, the knob responds to the control instruction to determine the target damping value and the target rotation angle of the brushless DC motor. Then the current position of the brushless DC motor is obtained, and the control voltage of the brushless DC motor is determined according to the current position and the target rotation angle. Finally, the brushless motor selection is controlled by the control voltage, so that the brushless DC motor rotates the target selection angle with the target damping value. In this way, the brushless DC motor rotates the target rotation angle from the current position based on the parameter adjustment interface selected by the user, and can provide the user with simulated force feedback through the target damping value, so that the user can obtain different operating experiences when operating the knob. At the same time, when the user selects different function options, the knob can perform different function controls on the interface corresponding to the target function option. While improving the user's operating experience, the function reuse of the knob is realized, and the functional range of the knob is expanded.

[0074] Optionally, when the function option is a water level option, the knob displays a parameter adjustment interface, including:

[0075] The knob displays the gear values ​​corresponding to different water levels at equal intervals in a clockwise direction.

[0076] When the function option is temperature option, the knob displays the parameter adjustment interface, including:

[0077] The knob displays the gear values ​​corresponding to different temperatures at equal intervals in a clockwise direction.

[0078] When the function option is the washing speed option, the knob displays the parameter adjustment interface, including:

[0079] The knob displays the gear values ​​corresponding to different washing speed values ​​at equal intervals in a clockwise direction.

[0080] In this way, it is helpful to intuitively display the gear values ​​corresponding to different types of function options to the user, so that the user can quickly lock the parameter adjustment interface corresponding to different function options, and improve the convenience of the user's gear selection. At the same time, the embodiment of the disclosure realizes the function reuse of the parameter adjustment interface. After the user sends a selection instruction, the knob can display the parameter adjustment interface corresponding to different function options, which is helpful to expand the functional range of the knob.

Optionally, the device may also include a communication interface (Communication Interface) 402 and a bus 403.
