DETAILED DESCRIPTION

[0062] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art based on the embodiments of the present application belong to the scope of protection of the present application.

[0063] Clothes processing devices, such as washing machines, have become common household appliances. The washing machine includes a control panel, and an operation knob is usually arranged on the control panel. The operation knob is twisted to start, stop, wash, and spin dry the washing machine. However, the knob in the related art cannot meet the use requirements of users.

[0064] Therefore, the embodiments of the present application provide a knob device, a control panel assembly, and a clothes processing device. The knob device includes a knob structure and a driving structure located inside a control panel of a clothes processing device. The driving structure drives the knob structure to move. When the knob structure is not used, the knob structure is moved to be hidden in the control panel to prevent the knob structure from being damaged or misoperated by pedestrians, and when the knob structure is needed, the knob structure is moved to protrude from the outer wall surface of the control panel to ensure the normal rotation of the knob structure and meet the use requirements of users. Meanwhile, a position detection structure is arranged to detect the moving position of the knob structure. A controller controls the working state of the driving structure according to the detection result of the position detection structure, thereby improving the accuracy of the moving stroke of the knob structure.

[0065] The knob device, the control panel assembly and the clothes processing device provided by the utility model will be described in detail below with specific embodiments in combination with the drawings.

[0066] Referring to Figures 1 to 12 The embodiment provides a knob device 103, which can be applied to a clothes processing device 100.

[0067] The clothes processing device 100 can be a washing machine, a clothes dryer, a washer-dryer or the like. The washing machine can be a drum washing machine or a pulsator washing machine or the like.

[0068] The clothes processing device 100 can include a cabinet 105 and a clothes processing drum (not shown in the figure) arranged in the cabinet 105. When in use, clothes or the like are placed in the clothes processing drum, and the clothes can be washed or the like by controlling the rotation of the clothes processing drum.

[0069] In specific implementation, the clothes processing device 100 can further include a general controller, and the general controller can be electrically connected to the clothes processing drum to control at least the starting and stopping of the rotation of the clothes processing drum.

[0070] Referring to Figures 1 to 3 The cabinet 105 is provided with a control panel assembly 101, and the control panel assembly 101 includes a control panel 102 and a knob device 103 arranged on the control panel 102.

[0071] The knob device 103 includes a knob structure 1, and at least part of the knob structure 1 can rotate relative to the control panel 102 to select the program of the clothes processing device 100, such as the starting, stopping, washing and dehydration of the clothes processing device 100. Of course, the knob structure 1 can also display a user interface (UI) to display the program and washing time of the clothes processing device 100, so as to realize the information interaction between the clothes processing device 100 and the user.

[0072] Specifically, the knob device 103 further includes a driving structure 2 arranged on the inner side of the control panel 102.

[0073] The driving structure 2 is connected to the knob structure 1, and the driving structure 2 is used to drive the knob structure 1 to move, so that at least part of the knob structure 1 protrudes from the outer wall surface 1021 of the control panel 102, or the knob structure 1 moves to not protrude from the outer wall surface 1021 of the control panel 102.

[0074] Referring to Figures 5 to 8A position detection structure 3 is provided between the knob structure 1 and the drive structure 2. The position detection structure 3 is electrically connected to both the drive structure 2 and the controller of the garment processing device 100. The position detection structure 3 is used to detect the movement position of the knob structure 1 relative to the control panel 102. The controller is used to control the working state of the drive structure 2 based on the position information detected by the position detection structure 3. The controller of the garment processing device 100 can specifically refer to the main controller of the garment processing device 100, or it can refer to a separate controller for the knob structure 1.

[0075] For example, the working state of the control drive structure 2 may include: the control drive structure 2 being turned on to drive the knob structure 1 to move; the control drive structure 2 being turned off to stop the knob structure 1 from moving, etc. Specifically, turning on the control drive structure 2 may include starting the drive structure 2 to work, or adjusting the movement speed of the knob structure 1 through the drive structure 2, etc.

[0076] Specifically, the knob structure 1 can be moved to a position where it does not protrude from the outer wall surface 1021 of the control panel 102. This can be either the outer wall surface of the knob structure 1 being located inside the outer wall surface 1021 of the control panel 102, or the outer wall surface of the knob structure 1 being flush with the outer wall surface 1021 of the control panel 102.

[0077] For example, a button electrically connected to the controller can be provided on the control panel 102, so that the controller can control the drive structure 2 to drive the knob structure 1 to move when the button is clicked, so that at least part of the knob structure 1 moves to protrude from the outer wall surface 1021 of the control panel 102, or moves the knob structure 1 to not protrude from the outer wall surface 1021 of the control panel 102.

[0078] For example, when the clothing processing equipment 100 is a drum washing machine, etc., refer to Figure 1 and Figure 2 The garment handling device 100 may also include a front sealing door assembly 106 connected to the front side of the housing 105. The front sealing door assembly 106 has a garment inlet communicating with the garment handling cylinder, and a door assembly 107 is provided on the front sealing door assembly 106. The door assembly 107 can be rotatably connected to the front sealing door assembly 106 to open or close the garment inlet.

[0079] Reference Figure 2 When the laundry processing device 100 is a drum washing machine, the control panel assembly 101 can be located on the front side of the cabinet 105 (e.g., along the edge of the cabinet 105). Figure 2 (on the right side), and positioned above the front sealing door assembly 106. Where at least a portion of the knob structure 1 protrudes from the outer wall 1021 of the control panel 102, the knob structure 1 can be rearward (e.g., along the body 105). Figure 2to the outer wall surface 1021 of the control panel 102.

[0080] When the laundry treating apparatus 100 is a pulsator washing machine (not shown in the figure), at this time, the control panel assembly 101 can be arranged at the top of the cabinet 105, and at least part of the knob structure 1 can be moved downward in the height direction of the laundry treating apparatus 100 to not protrude from the outer wall surface 1021 of the control panel 102 when protruding from the outer wall surface 1021 of the control panel 102.

[0081] The knob device provided by the embodiment can realize the adjustment of the position of the knob structure 1 relative to the control panel 102 by arranging the knob structure 1 and the driving structure 2 inside the control panel 102, connecting the driving structure 2 and the knob structure 1, and driving the knob structure 1 to move by the driving structure 2, so that at least part of the knob structure 1 protrudes from the outer wall surface 1021 of the control panel 102 or the knob structure 1 is moved to not protrude from the outer wall surface 1021 of the control panel 102. In this way, when the knob structure 1 is not needed to be used, the knob structure 1 can be hidden in the control panel 102 by moving the knob structure 1 to not protrude from the outer wall surface 1021 of the control panel 102, so that the damage or misoperation of the knob structure 1 caused by the accidental collision of the passing pedestrians and the like can be avoided to a certain extent, the knob structure 1 is protected to a certain extent, and the accumulation of dirt on the knob structure 1 can be avoided to a certain extent. In addition, by hiding the knob structure 1 in the control panel 102, the appearance flatness of the control panel 102 can be improved to a certain extent, so that the appearance beauty of the laundry treating apparatus 100 is improved, and the user experience is improved. When the knob structure 1 needs to be used, at least part of the knob structure 1 can be moved to protrude from the outer wall surface 1021 of the control panel 102 by the driving structure 2, so that the knob structure 1 can be conveniently screwed to perform the program selection and other operations of the laundry treating apparatus 100.

[0082] In addition, when the control panel 102 is arranged at the top of the cabinet 105 of the laundry treating apparatus 100, since the knob structure 1 can be moved to not protrude from the outer wall surface 1021 of the control panel 102, the user can conveniently place the laundry, detergent and other articles on the control panel 102, and the space utilization rate is improved.

[0083] Meanwhile, by arranging the position detection structure 3 between the knob structure 1 and the driving structure 2, and electrically connecting the position detection structure 3 with the driving structure 2 and the controller of the clothes treatment equipment 100 respectively, the position detection structure 3 is used to detect the movement position of the knob structure 1 relative to the control panel 102, and the controller is used to control the working state of the driving structure 2 according to the position information detected by the position detection structure 3. In this way, the movement position of the knob structure 1 can be detected in real time by the position detection structure 3 during the movement of the knob structure 1 driven by the driving structure 2, and the controller can control the working state of the driving structure 2 according to the detection result of the position detection structure 3. For example, when the knob structure 1 is driven by the driving structure 2 to move to the limit position protruding from the outer wall surface 1021 of the control panel 102 and / or not protruding from the outer wall surface 1021 of the control panel 102, the controller can control the driving structure 2 to stop driving the knob structure 1, so that the movement of the knob structure 1 can be stopped in time, improving the accuracy of the movement stroke of the knob structure 1, thereby avoiding the situation that the knob structure 1 moves excessively and collides with other components to a certain extent, ensuring the safety of the movement of the knob structure 1, and helping to improve the user experience.

[0084] In some embodiments, with reference to Figures 1 to 3 As shown, the control panel 102 has a through hole 104, and the knob structure 1 is arranged in the through hole 104 to move to the outside of the through hole 104 or to move into the through hole 104 under the driving of the driving structure 2.

[0085] That is, when the knob structure 1 moves to the outside of the through hole 104, at least part of the knob structure 1 protrudes from the outer wall surface 1021 of the control panel 102; when the knob structure 1 moves into the through hole 104, the knob structure 1 does not protrude from the outer wall surface 1021 of the control panel 102.

[0086] Since the knob structure 1 is arranged in the through hole 104, the through hole 104 can guide the knob structure 1 to a certain extent when the knob structure 1 moves, thereby ensuring the stability of the movement of the knob structure 1, facilitating the position adjustment of the knob structure 1, and enabling the knob structure 1 to move into the through hole 104 when not in use, thereby achieving good protection of the knob structure 1.

[0087] In other implementations, the through hole 104 can also not be arranged, specifically, the control panel 102 can have a avoiding area for avoiding the knob structure 1, and the knob structure 1 can move to protrude from the outer wall surface 1021 of the control panel 102 or not to protrude from the outer wall surface 1021 of the control panel 102 through the avoiding area.

[0088] In some embodiments, with reference to Figures 4 to 8As shown, the position detecting structure 3 comprises at least two detecting members 30, each of which is electrically connected to the controller. Among all the detecting members 30, at least two of them are arranged in a spaced manner along the movement direction of the knob structure 1. The controller is configured to stop the driving structure 2 from working when at least one of the detecting members 30 detects that the knob structure 1 moves to protrude from the outer wall surface 1021 of the control panel 102, and to stop the driving structure 2 from working when at least another of the detecting members 30 detects that the knob structure 1 moves to not protrude from the outer wall surface 1021 of the control panel 102. Here, the movement direction of the knob structure 1 may, for example, be the upward and downward direction in Figure 4 、 Figure 5 , the Z direction in Figure 6 .

[0089] In this way, the movement of the knob structure 1 to the two extreme positions of protruding from and not protruding from the outer wall surface 1021 of the control panel 102 can be detected by the at least two detecting members 30, so as to further ensure the accuracy of the movement stroke of the knob structure 1, thereby ensuring the good hiding of the knob structure 1 when not in use and the normal rotation of the knob structure 1 when in use. Moreover, this can further avoid the situation that the knob structure 1 moves excessively and collides with the external structure, thereby protecting the knob structure 1.

[0090] Of course, in other embodiments, only one detecting member 30 can be provided, and the controller is configured to stop the driving structure 2 from working when this detecting member 30 detects that the knob structure 1 moves to protrude from the outer wall surface 1021 of the control panel 102, or the controller is configured to stop the driving structure 2 from working when this detecting member 30 detects that the knob structure 1 moves to not protrude from the outer wall surface 1021 of the control panel 102.

[0091] In some embodiments, as shown in Figures 6 to 8 , the detecting member 30 has a first gap 301, and the knob device 103 further comprises a triggering part 13, and the controller is configured to control the driving structure 2 to stop working when the detecting member 30 detects that the triggering part 13 is located in the first gap 301.

[0092] Thus, when the detection member 30 detects that the triggering portion 13 is located in the first gap 301 of the detection member 30, it indicates that the knob structure 1 is moved to a position protruding from the outer wall surface 1021 of the control panel 102 or a position not protruding from the outer wall surface 1021 of the control panel 102, the detection of the movement position of the knob structure 1 is convenient, thereby facilitating the controller to control the driving structure 2 to stop working to stop the movement of the knob structure 1, ensuring the accuracy of the movement stroke of the knob structure 1, and preventing the knob structure 1 from over-movement and interfering with other structures. At the same time, by setting the triggering portion 13, the detection is more convenient and flexible.

[0093] Moreover, by setting the first gap 301 on the detection member 30, the knob device 103 includes the triggering portion 13, and the triggering portion 13 can extend into the first gap 301, so that while realizing the detection of the movement position of the knob structure 1, the occupied space of the entire knob device 103 can be reduced, which is beneficial to the development of the laundry treatment apparatus 100 towards small size.

[0094] In some embodiments, referring to Figures 6 to 10 , specifically, the knob structure 1 can have the triggering portion 13.

[0095] In some embodiments, referring to Figures 6 to 10 , the knob structure 1 includes the knob member 11 and the intermediate assembly 12. The knob member 11 is rotationally connected to the intermediate assembly 12, and the intermediate assembly 12 is connected to the driving structure 2 to drive the knob member 11 to move under the driving of the driving structure 2. The triggering portion 13 is located on the intermediate assembly 12.

[0096] Thus, while realizing the detection of the movement position of the knob structure 1 to improve the accuracy of the movement stroke of the knob structure 1, compared with the scheme of setting the triggering portion on the knob member, such setting will not affect the normal screwing of the knob member 11.

[0097] Referring to Figure 10 , the intermediate assembly 12 can include a connecting member 121 and a moving member 122, for example, the knob member 11 can be rotationally connected to the connecting member 121, the moving member 122 can be connected to the side of the connecting member 121 away from the knob member 11, and the moving member 122 can be connected to the driving structure 2.

[0098] For example, the connecting member 121 and the moving member 122 can be detachably connected by screws, buckles, etc. For example, the knob member 11 can include a knob portion (not shown in the figure) and a mounting portion (not shown in the figure) rotationally connected, and the knob portion can be rotationally connected to the connecting member 121 through the mounting portion, for example, the mounting portion and the connecting member 121 can be connected by screws, buckles, etc.

[0099] In some embodiments, referring to Figure 6 and Figure 8 , the trigger part 13 can be a trigger plate, so as to further reduce the occupied space of the knob device 103 while achieving accurate detection of the movement position of the knob structure 1, and further achieve small size of the clothes treatment equipment 100.

[0100] Of course, the trigger part 13 can also be a trigger block and the like.

[0101] In some embodiments, referring to Figures 6 to 8 , the detection piece 30 includes a light emitting part 31 and a receiving part 32 for electrical connection with the controller. The light emitting part 31 and the receiving part 32 are oppositely arranged, and a first gap 301 is formed between the light emitting part 31 and the receiving part 32. The light emitting direction of the light emitting part 31 is towards the receiving part 32, and the controller is used to control the working state of the driving structure 2 according to the light intensity received by the receiving part 32.

[0102] In this way, when the trigger part 13 is located outside the first gap 301, the light emitted by the light emitting part 31 will be directly received by the receiving part 32, and when the trigger part 13 is located within the first gap 301, the trigger part 13 will shield the light emitted by the light emitting part 31. At this time, the light intensity received by the receiving part 32 will be weakened or even disappeared, so that the detection piece 30 can be formed as a light-sensitive stroke sensor, and accurate detection of the movement position of the knob structure 1 can be achieved, and detection is convenient.

[0103] Of course, in other implementations, the detection piece 30 can also include a magnetic field generator and a magnetic field inductor, so that the position detection structure 3 is formed as a magnetic-electric stroke sensor. Or the position detection structure 3 can also be a camera and the like.

[0104] In some embodiments, referring to Figures 4 to 10 , the knob device 103 further includes a mounting body 4 connected inside the control panel 102. The mounting body 4 has a containing cavity 40, and the side of the containing cavity 40 facing the control panel 102 has an opening. The knob structure 1 is located in the containing cavity 40, and the driving structure 2 is used to drive the knob structure 1 to move relative to the control panel 102 through the opening. The position detection structure 3 is arranged on the mounting body 4.

[0105] In this way, the position detection structure 3 can be arranged inside the control panel 102, so that the position detection structure 3 can be protected to a certain extent, and the accurate detection of the position detection structure 3 on the movement position of the knob structure 1 can be ensured, and the accuracy of the movement stroke of the knob structure 1 is further ensured, so that the knob structure 1 can be further prevented from excessive movement and collision interference with other structures. At the same time, compared with the scheme of arranging the position detection structure on the knob structure, the movement position of the knob structure 1 can be detected while the normal movement and use of the knob structure 1 are not affected, so that the smooth movement of the knob structure 1 can be ensured, and the position detection structure 3 can be protected. In addition, by arranging the knob structure 1 in the accommodating cavity 40, the knob structure 1 can be protected to a certain extent, and the movement of the knob structure 1 can be guided to a certain extent by the accommodating cavity 40, so as to further ensure the stability of the movement of the knob structure 1 and realize the stable adjustment of the position of the knob structure 1.

[0106] For example, referring to Figure 5 The mounting body 4 can include a seat body 41 and a cover body 42 connected to the side of the seat body 41 facing the control panel 102. For example, a detection piece 30 can be arranged on the seat body 41 and the cover body 42, respectively. When the knob structure 1 moves out of the outer wall surface 1021 of the control panel 102, the trigger portion 13 extends into the first gap 301 of the detection piece 30 on the seat body 41. When the knob structure 1 moves out of the outer wall surface 1021 of the control panel 102, the trigger portion 13 extends into the first gap 301 of the detection piece 30 on the cover body 42.

[0107] In some embodiments, the position detection structure 3 and the mounting body 4 are detachably connected. In this way, when one of the position detection structure 3 and the mounting body 4 is damaged, only the damaged part needs to be replaced, so that the position detection structure 3 and the mounting body 4 as a whole can be avoided from being scrapped, and the maintenance and use cost can be saved.

[0108] For example, referring to Figure 6 The detection piece 30 can further include a fixing portion 33, and the fixing portion 33 and the mounting body 4 can be detachably connected by screws, buckles or the like.

[0109] Of course, in other implementations, the detection piece 30 can be arranged on the knob structure 1, and the trigger portion 13 can be arranged on the mounting body 4. When the controller detects that the trigger portion 13 extends into the first gap 301 of the detection piece 30, the controller stops driving the knob structure 1.

[0110] In some embodiments, referring to Figures 7 to 10As shown, the driving structure 2 comprises a driving member (not shown in the figure) and a transmission assembly 21. The driving member is connected with the transmission assembly 21, the transmission assembly 21 is connected with the knob structure 1, and the driving member is used to rotate the transmission assembly 21 to drive the knob structure 1 to move.

[0111] In this way, by controlling the driving member to work to drive the transmission assembly 21 to rotate, the knob structure 1 can be driven by the transmission assembly 21 to move to adjust the position of the knob structure 1 relative to the control panel 102, so that the knob structure 1 can be moved to not protrude from the outer wall surface 1021 of the control panel 102 when not in use, thereby achieving a certain degree of hidden protection of the knob structure 1, avoiding the situation that the knob structure 1 is accidentally collided, and moving the knob structure 1 to protrude from the outer wall surface 1021 of the control panel 102 when needed, thereby ensuring the normal rotation of the knob structure 1.

[0112] Meanwhile, compared with the scheme of driving the knob structure to rotate to adjust the position of the knob structure, the embodiment can save the movement space required by the knob structure 1 to a certain extent while adjusting the position of the knob structure 1, thereby being conducive to realizing the miniaturization of the control panel 102, and further saving the occupied space of the clothes treatment equipment 100.

[0113] Among them, with reference to Figures 1 to 12 Taking the clothes treatment equipment 100 as a drum washing machine for example, the moving direction of the knob structure 1 is Figure 2 the left-right direction in Figure 4 , Figure 5 and Figure 10 the up-down direction, Figure 6 the Z direction in

[0114] Specifically, the driving member can be connected to the seat body 41, and the knob device 103 can be connected to the control panel 102 through the cover body 42, so that when the knob device 103 is installed, the entire driving structure 2 can be connected and integrated on the seat body 41 first, and then the seat body 41 integrated with the driving structure 2 is connected with the cover body 42, and then the cover body 42 is connected to the control panel 102, thereby realizing the connection of the knob device 103 on the control panel 102, which is convenient and efficient.

[0115] In some embodiments, with reference to Figures 6 to 12As shown, a guide mechanism 5 is arranged between the mounting body 4 and the knob structure 1, so that the knob structure 1 is guided by the guide mechanism 5 to move to the outside of the control panel 102 to protrude from the outer wall surface 1021 of the control panel 102 or to move to the inside of the control panel 102 to not protrude from the outer wall surface 1021 of the control panel 102 when the driving member drives the transmission assembly 21 to rotate.

[0116] In this way, the knob structure 1 can move along a preset track under the driving of the driving structure 2 to adjust the position of the knob structure 1 by arranging the guide mechanism 5, and the arrangement of the guide mechanism 5 can also improve the stability of the knob structure 1 to a certain extent when moving, ensure reliable adjustment of the position of the knob structure 1, and shorten the moving path to realize quick adjustment of the position of the knob structure 1 and further improve the user experience.

[0117] In some embodiments, referring to Figures 6 to 12 As shown, the intermediate assembly 12 is connected with the transmission assembly 21 to move and drive the knob member 11 to move when the driving member drives the transmission assembly 21 to rotate. The guide mechanism 5 is arranged between the intermediate assembly 12 and the mounting body 4.

[0118] In this way, the knob structure 1 can be guided to adjust the position of the knob member 11, and compared with the scheme of arranging the guide mechanism between the knob member and the mounting body, the normal screwing of the knob member 11 will not be affected.

[0119] In some embodiments, referring to Figure 10 As shown, the transmission assembly 21 includes a first transmission member 211 and a second transmission member 212. The driving member is connected with one end of the first transmission member 211, the other end of the first transmission member 211 is rotationally connected with one end of the second transmission member 212, and the other end of the second transmission member 212 is rotationally connected with the knob structure 1. The driving member is used to drive the first transmission member 211 to rotate to move the knob structure 1.

[0120] In this way, the driving member is controlled to work to control the first transmission member 211 to rotate relative to the control panel 102, and the second transmission member 212 is driven to rotate by the first transmission member 211, so that a crank slider structure can be formed between the driving member, the transmission assembly 21, the guide mechanism 5 and the knob structure 1, thereby realizing the movement of the knob structure 1 to adjust the position of the knob structure 1, so that the knob structure 1 can be moved to not protrude from the outer wall surface 1021 of the control panel 102 when not in use, thereby achieving a certain degree of protection of the knob structure 1, convenient and flexible to use.

[0121] For example, the first transmission member 211 and the second transmission member 212 can be transmission rods or transmission plates, etc.

[0122] For example, the driving member can include a driving motor having an output shaft, and one end of the first transmission member 211 can be connected to the output shaft. The driving motor can be a stepper motor, which receives a control signal from a controller and converts the control signal into angular displacement of the output shaft of the stepper motor to rotate the first transmission member 211. In addition, the driving motor can also be a direct drive motor or the like.

[0123] Of course, the driving member can also include a matching gear and a rack, and the gear can be connected to one end of the first transmission member 211. The gear can rotate when the rack moves and drive the first transmission member 211 to rotate.

[0124] In addition, the transmission assembly 21 can also include a transmission cam and a transmission push rod. The driving member is connected to the transmission cam to drive the transmission cam to rotate. The transmission push rod is abutted to the outer circumferential surface of the transmission cam, and the transmission push rod is connected to the knob structure 1 to form a cam push rod structure.

[0125] Alternatively, the transmission assembly 21 can also include a lead screw, and a matching thread is provided on the knob structure 1 to match the outer thread of the lead screw. The driving member drives the lead screw to rotate to drive the knob structure 1 to move. Alternatively, the transmission assembly 21 can also include a transmission gear and a transmission rack that match each other. The driving member is connected to the transmission gear, and the transmission rack is connected to the knob structure 1. The driving member drives the transmission gear to rotate to drive the transmission rack and the knob structure 1 to move.

[0126] In some embodiments, referring to Figures 10 to 12 As shown, the guide mechanism 5 includes a first guide structure 621. The mounting body 4 is provided with a ring-shaped member 6, which is sleeved outside the knob structure 1 and the knob structure 1 can move in the axial direction of the ring-shaped member 6. The inner wall surface of the ring-shaped member 6 is formed as the first guide structure 621 to guide the knob structure 1. The axial direction of the ring-shaped member 6 can be the up-down direction in Figure 10 , Figure 12 the Z direction in .

[0127] In this way, the inner wall surface of the ring-shaped member 6 can be used to guide the knob structure 1, so that the knob structure 1 can move under the driving of the driving structure 2 to achieve stable adjustment of the position of the knob structure 1.

[0128] In some embodiments, referring to Figures 10 to 12 As shown, the ring-shaped member 6 includes a ring-shaped body 61 and a protruding portion 62. The protruding portion 62 is provided on the inner wall surface of the ring-shaped body 61 and protrudes towards the inner cavity of the ring-shaped body 61. The knob structure 1 can move along the inner wall surface of the protruding portion 62, and the inner wall surface of the protruding portion 62 is formed as at least part of the first guide structure 621.

[0129] Thus, while the ring-shaped member 6 guides the knob structure 1, compared with the solution in which the inner wall surface of the ring-shaped body is formed as the first guide structure without the protruding portion, the gap between the first guide structure 621 and the knob structure 1 in the radial direction of the ring-shaped member 6 (the left-right direction in Figure 10 , Figure 11 and the X direction in Figure 12 ) can be reduced to some extent, so that the guiding effect on the knob structure 1 can be improved, and the stability of the movement of the knob structure 1 is further improved. Meanwhile, compared with the solution in which the diameter of the ring-shaped body is reduced to improve the guiding effect on the knob structure, the contact area between the first guide structure 621 and the knob structure 1 can also be reduced to some extent, so that the friction therebetween can be reduced to some extent, and thus the smoothness of the movement of the knob structure 1 can be improved while ensuring the guiding effect.

[0130] In addition, the protruding portion 62 can also play a role in structurally reinforcing the ring-shaped body 61, so as to be beneficial to prolong the service life of the ring-shaped member 6, ensure the reliable guidance of the ring-shaped member 6 on the knob structure 1, and ensure the stable movement of the knob structure 1.

[0131] Specifically, referring to Figure 10 and Figure 11 , the connecting member 121 of the knob structure 1 moves along the inner wall surface of the protruding portion 62.

[0132] Specifically, the ring-shaped member 6 can be a self-lubricating member, such as polyoxymethylene (POM) or polytetrafluoroethylene (PTFE), so as to reduce the friction between the ring-shaped member 6 and the knob structure 1.

[0133] Specifically, the ring-shaped body 61 can be arranged along the circumference of the through hole 104, so that while guiding the knob structure 1, the ring-shaped body 61 can also shield and protect the structure inside the control panel 102, so as to avoid the damage of the structure inside the control panel 102 to some extent, avoid the damage of the internal structure caused by the child's curiosity to insert a rod-shaped member from the gap between the knob structure 1 and the through hole 104, and also avoid the entry of insects, dust, etc. into the interior of the laundry treatment apparatus 100.

[0134] Specifically, the ring-shaped body 61 can be connected to the mounting body 4 by screws, buckles, etc.

[0135] In some embodiments, referring to Figure 11As shown, the inner wall surface of the protruding portion 62 and the outer wall surface of the knob structure 1 have a second gap 60 in the radial direction of the annular body 61. Figure 10 、 Figure 11 The second gap 60 refers to the gap d between the inner wall surface of the protruding portion 62 and the outer wall surface 1021 of the knob structure 1 in the left-right direction of Figure 11

[0136] In this way, the protruding portion 62 can guide the knob structure 1 to improve the stability of the movement of the knob structure 1, and can also avoid friction between the inner wall surface of the protruding portion 62 and the knob structure 1 to some extent, thereby ensuring the smoothness of the movement of the knob structure 1.

[0137] In some embodiments, the size of the second gap 60 in the radial direction of the annular body 61 is between 0.05mm and 0.1mm.

[0138] For example, the size of the second gap 60 can be 0.05mm, 0.06mm, 0.07mm, 0.075mm, 0.08mm, 0.09mm, or 0.1mm.

[0139] In this way, the guiding effect of the protruding portion 62 on the knob structure 1 can be ensured to some extent, the stability of the movement of the knob structure 1 is further improved, and the friction between the protruding portion 62 and the knob structure 1 can be avoided to some extent, thereby further ensuring the smoothness of the movement of the knob structure 1. Furthermore, such an arrangement can also avoid the situation that the size of the second gap 60 is too large, thereby preventing the entire knob device 103 from being too large, and facilitating the miniaturization design of the clothes treatment apparatus 100.

[0140] In some embodiments, referring to Figure 12 As shown, the protruding portion 62 includes at least two protruding portions 62 arranged at intervals in the circumferential direction of the annular body 61.

[0141] In this way, the knob structure 1 can be guided from multiple positions, thereby further improving the guiding effect on the knob structure 1, and further improving the stability of the movement of the knob structure 1.

[0142] For example, referring to Figure 12 The at least two protruding portions 62 can be uniformly arranged in the circumferential direction of the annular body 61 to further ensure the guiding effect.

[0143] In some embodiments, referring to Figure 12 As shown, the protruding portion 62 includes a protruding rib extending in the axial direction of the annular body 61. The axial direction of the annular body 61 may, for example,​Figure 12 The Z-direction in the middle.

[0144] This further ensures the guiding effect of the protrusion 62 on the knob structure 1, making the movement of the knob structure 1 more stable and the position adjustment of the knob structure 1 more reliable. Moreover, this can also improve the structural reinforcement effect of the protrusion 62 on the annular body 61 to a certain extent, which is conducive to further extending the service life of the annular part 6.

[0145] Of course, in other implementations, the protrusion 62 can also be a bump, etc.

[0146] In some embodiments, the protrusion 62 is integrally formed with the annular body 61, which makes the overall structural strength of the protrusion 62 and the annular body 61 high, thereby further ensuring the guiding effect on the knob structure 1, the stability of the movement of the knob structure 1 is high, and the protrusion 62 has a good structural reinforcement effect on the annular body 61. At the same time, this also facilitates subsequent assembly.

[0147] Reference Figure 12 The annular member 6 may also include a mounting portion 63, through which the annular member 6 is connected to the mounting body 4. For example, the mounting portion 63 may be a mounting hole, and the annular member 6 may be connected to the mounting body 4 by a screw or the like passing through the mounting hole. Alternatively, the mounting portion 63 may also be a mounting buckle, and the mounting body 4 may have a locking hole for the mounting buckle to extend into and engage.

[0148] In some embodiments, refer to Figures 6 to 9 As shown, the guide mechanism 5 includes a second guide structure 51. The second guide structure 51 includes a guide hole 511 disposed on the knob structure 1 and a guide protrusion 512 disposed on the mounting body 4. The guide protrusion 512 passes through the guide hole 511 to guide the knob structure 1.

[0149] With this configuration, the knob structure 1 can be moved along a preset path under the drive of the drive structure 2 through the cooperation of the guide hole 511 and the guide protrusion 512. This ensures the stability of the movement of the knob structure 1 and shortens the movement path, thereby realizing the rapid adjustment of the knob structure 1 and further improving the user experience.

[0150] For example, the guide protrusion can be a guide post, a guide block, etc.

[0151] Of course, in other embodiments, a guide protrusion may be provided on the knob structure 1, and a guide hole may be provided on the mounting body 4.

[0152] In addition, in other implementations, a guide slider can be provided on the knob structure 1, and a guide groove can be provided on the mounting body 4 for the guide slider to extend into and slide.

[0153] In some embodiments, referring to Figure 9 As shown in the figure, at least part of the hole wall of the guide hole 511 is protruded to form a protrusion 513 towards the direction close to the center of the guide hole 511.

[0154] In this way, compared with the solution of reducing the aperture of the guide hole, the assembly convenience of the guide protrusion 512 and the guide hole 511 can be improved, and the matching precision of the guide hole 511 and the guide protrusion 512 can be ensured to a certain extent, so that the shaking of the guide protrusion 512 when moving along the guide hole 511 can be prevented to a certain extent, the guiding effect of the guide hole 511 on the guide protrusion 512 is ensured, and the stability of the movement of the knob structure 1 can be further improved; and in this way, the contact area between the hole wall of the guide hole 511 and the guide protrusion 512 can be reduced to a certain extent, so that the friction between the guide hole 511 and the guide protrusion 512 can be reduced, and the guiding effect on the knob structure 1 can be further improved, ensuring smooth movement of the knob structure 1, and the user experience is better.

[0155] In some embodiments, referring to Figure 9 As shown in the figure, the protrusion 513 is at least two, and the at least two protrusions 513 are arranged at intervals along the circumference of the guide hole 511.

[0156] In this way, the assembly convenience of the guide protrusion 512 and the guide hole 511 and the matching precision of the two can be further improved, so that the guiding effect on the knob structure 1 is further improved, and the smoothness of the movement of the knob structure 1 is higher.

[0157] In some embodiments, referring to Figures 6 to 7 As shown in the figure, the guide hole 511 is at least two, and the at least two guide holes 511 are arranged at intervals on the knob structure 1. The guide protrusion 512 is at least two, and corresponds to the guide hole 511 one by one.

[0158] In this way, the knob structure 1 can be guided at multiple positions, and the guiding effect on the knob structure 1 is improved, so that the stability of the movement of the knob structure 1 can be further improved.

[0159] The embodiment also provides a control panel assembly 101, which comprises a control panel 102 and a knob device 103. The knob device 103 is arranged on the control panel 102.

[0161] In some embodiments, when the knob structure 1 moves into the through hole 104, the outer wall surface of the knob structure 1 is flush with the outer wall surface 1021 of the control panel 102.

[0162] In this way, the knob structure 1 can be further hidden, so as to further avoid the knob structure 1 from being damaged or misoperated due to accidental collision, thereby improving the protection effect of the knob structure 1, and making the appearance of the control panel assembly 101 more flat, so as to further improve the appearance aesthetics of the clothes processing equipment 100, and provide a better user experience.

[0163] The embodiment also provides a clothes processing equipment 100, which comprises a control panel 102 and a knob device 103.
