Description

Technical Field

[0001] This application relates to the field of clothing processing technology, and in particular to a knob device for clothing processing equipment and clothing processing equipment. Background Technology

[0002] Most garment processing equipment (such as dryers and washing machines) uses knobs to adjust washing parameters to meet the washing needs of different fabrics and different cleaning requirements.

[0003] The knobs on garment processing equipment generally protrude from the outer wall of the front panel. When the knobs are not in use, they not only affect the overall appearance and aesthetics of the garment processing equipment, but also may be damaged.

[0004] Currently, there are instances where the knob is used to adjust the washing parameters and then retracted to the front panel, only to retract again when the washing parameters need to be adjusted again.

[0005] However, after the knob extends out of the front panel surface, when the knob needs to retract into the front panel, there is a positional misalignment that prevents it from retracting, affecting the user experience. Utility Model Content

[0053] To make the technical solution and beneficial effects of this utility model more apparent and understandable, a detailed description is provided below by listing specific embodiments. The accompanying drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application pertains.

[0054] In the description of this utility model, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "height", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. In other words, they should not be construed as limitations on this utility model.

[0055] In this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating the relative importance of the indicated features or the number of indicated technical features. Therefore, a feature specified as "first" or "second" can explicitly indicate that at least one of those features is included. In the description of this utility model, "multiple" means at least two, such as two, three, etc.; "several" means at least one, such as one, two, three, etc., unless otherwise explicitly specified.

[0056] In this utility model, unless otherwise explicitly defined, the terms "installation," "connection," "linking," "fixing," and "setting," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can also refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0057] In this utility model, unless otherwise explicitly defined, the terms "above," "on top of," "above," "over," "below," "below," "below," or "below" for "first feature above second feature" can refer to direct contact between the first and second features, or indirect contact between the first and second features through an intermediate medium.

Similarly, "below," "below," and "below" for "first feature below second feature" can mean the first feature is directly below or diagonally below the second feature, or simply indicates that the horizontal height of the first feature is lower than the horizontal height of the second feature.

[0058] The existing technology requires the knob to be turned out and fully protrude from the outer wall of the front panel when adjusting washing parameters. However, the gap between the knob and the front panel is relatively large, and the knob may shift position after being fully turned out, making it unable to retract, which affects the user experience.

[0059] Based on this, this application provides a knob device 4. When the knob device 4 is rotated out to its maximum stroke on the outer wall 111 of the front panel, a portion of the knob device 4 is still located inside the front panel 11, so that the knob device 4 can be rotated back smoothly. This avoids the situation where the knob device 4 cannot be retracted due to possible positional displacement when it is fully rotated out, thus improving the user experience.

[0060] The clothing processing device 100 in this embodiment can be a washing machine, a dryer, a washer-dryer combo, etc. The washing machine can be a front-loading washing machine or a top-loading washing machine.

[0061] Please refer to Figure 1a , Figure 1b and Figure 2 The garment processing equipment 100 includes a housing 1, a front cover 33, and a knob device 4.

[0062] The housing 1 has a front panel 11, and a front cover 33 is rotatably mounted on the front panel 11. The front cover 33 is opened to place items to be washed. A mounting hole (not shown in the figure) for mounting the knob device 4 can be provided on the front panel 11 or on the front cover 33. The knob device 4 can rotate, extend and retract relative to the front panel 11 or the front cover 33 within the mounting hole. Figure 1b A schematic diagram of the structure of the knob device located on the front panel 11 is shown.

[0063] The garment handling equipment 100 also includes a control panel 32. The front panel 11 has a front sealing door 112. The control panel 32 is mounted on the front panel 11 and located above the front cover 33 and the front sealing door 112 for user operation. A mounting hole for mounting a knob device 4 is provided on the control panel 32 or the front sealing door 112. The knob device 4 can rotate, extend, and retract relative to the control panel 32 or the front sealing door 112 within the mounting hole.

[0064] The washing mode and parameters of the garment processing equipment 100 can be selected by rotating the knob device 4. For example, the garment processing equipment 100 can be selected for rinsing, drying, dehydration, washing, etc. Of course, the washing mode and parameters of the garment processing equipment 100 can also be selected by combining the knob device 4 with the front panel 11, for example, the garment processing equipment 100 can be selected for heavy-duty washing, gentle washing, etc.

[0065] The following embodiment uses the example of a mounting hole located on the control panel 32 as an example for illustration.

[0066] Figure 1 shows a schematic diagram of the knob device 4 retracted into the control panel 32.

[0067] Figure 2 The diagram shows the state of the knob device 4 extending out of the outer wall of the control panel 32.

[0068] For details, please refer to Figures 3 to 6 The knob device 4 includes a drive assembly 43, a transmission assembly 42, and a knob assembly 41.

[0069] One end of the transmission component 42 is connected to the drive component 43, which generates driving force to drive the transmission component 42 to move.

[0070] The knob assembly 41 includes a knob housing 411 and a knob body 412. The knob housing 411 is sleeved on the knob body 412. The other end of the transmission assembly 42 is connected to the knob body 412. The knob assembly 41 moves with the transmission assembly 42 under the driving action of the drive assembly 43, so that in the first direction (i.e. Figure 4 The top end 4111 of the knob housing (in the direction of arrow s1 shown) protrudes from the outer wall surface 31 of the control panel, or does not protrude from the outer wall surface 31 of the control panel, with the first direction being the axial direction of the knob housing 411. For example, the drive assembly 43 is a motor, but it is not limited to this.

[0071] When the top end 4111 of the knob housing protrudes beyond the outer wall 31 of the control panel by the maximum travel distance, that is, when the knob housing 411 extends to the point where it can no longer move, the first area 411a provided at the bottom end 4112 of the knob housing is located in the mounting hole provided on the control panel 32 in the first direction.

[0072] Figure 3 The image shows a top view of control panel 32. Figure 4 for Figure 3 Sectional view at point AA. Figure 4 and Figure 5 The diagram shows the state when the top of the knob housing 4111 protrudes from the outer wall surface 31 of the control panel by the maximum travel distance. Figure 5 As shown, the first area 411a at the bottom end 4112 of the knob housing is located inside the mounting hole of the control panel 32 to ensure that the knob housing 411 can be smoothly retracted into the control panel 32, thereby improving the user experience.

[0073] In one alternative embodiment, please refer to Figure 6 The surface of the knob housing 411 is provided with anti-slip texture 4114.

[0074] The side wall of the knob housing 411 is provided with an operation area 411c and a hidden area 411b. The operation area 411c and the hidden area 411b are arranged adjacent to each other. The anti-slip texture 4114 is located in the operation area 411c. The anti-slip texture 4114 increases the friction between the user's fingers and the knob housing 411, thereby improving the user's operating experience.

[0075] The hidden area 411b is the first area 411a of the knob housing 411, that is, when the distance by which the knob housing 411 protrudes from the outer wall surface 31 of the control panel is the maximum stroke, the area where the knob housing 411 is located within the control panel 32.

[0076] This can be understood as the fact that the hidden area 411b does not have anti-slip texture 4114, which can reduce the friction between the knob housing 411 and the inner wall of the mounting hole of the control panel 32 during rotation, and ensure the user's operating feel when operating the knob assembly 41.

[0077] In an alternative embodiment, the first region 411a of the knob housing 411 is in the first direction (i.e. Figure 5 The arrow s1 shown has a first length, that is... Figure 5 The L1 shown has a first length range greater than or equal to 1.5 mm.

[0078] The first length range is greater than or equal to 1.5mm, which can ensure the smoothness of the knob housing 411 when it retracts into the control panel 32, greatly reducing the possibility of the knob housing 411 getting stuck when it retracts into the control panel 32, and ensuring the user experience.

[0079] When the first length of the first region 411a of the knob housing 411 in the first direction is less than 1.5mm, when the knob housing 411 retracts into the control panel 32 and is offset, the bottom end 4112 of the knob housing will get stuck in the opening of the mounting hole of the control panel 32, causing the knob housing 411 to be unable to retract, or even damaging the knob housing 411, affecting the user experience.

[0080] In an optional embodiment, when the top end 4111 of the knob housing does not protrude from the outer wall surface 31 of the control panel, the end face 4113 of the knob housing is located inside the control panel 32, that is, the end face 4113 of the knob housing is located inside the mounting hole of the control panel 32. It can be understood that a groove is formed between the end face 4113 of the knob housing and the outer wall surface 31 of the control panel.

[0081] In one alternative embodiment, please refer to Figure 7 and Figure 8 When the top end 4111 of the knob housing does not protrude from the outer wall surface 31 of the control panel, the end face 4113 of the knob housing and the outer wall surface 31 of the control panel are on the same plane.

[0082] It can be understood that when the garment processing device 100 does not need to adjust the washing parameters and washing mode, the knob housing 411 retracts into the control panel 32, and the end face 4113 of the knob housing is on the same horizontal plane as the outer wall surface 31 of the control panel. This can improve the appearance consistency and aesthetics of the garment processing device 100, and can greatly reduce the entry of foreign objects into the mounting holes of the control panel 32 compared to the above embodiments.

[0083] In an optional embodiment, the top end 4111 of the knob housing can protrude from the outer wall surface 31 of the control panel at least by a first height and a second height, with the second height being greater than the first height, under the driving action of the drive assembly 43.

[0084] This can be understood as follows: the first and second heights at which the top of the knob housing protrudes from the outer wall surface 31 of the control panel correspond to different washing modes of the garment processing device 100. For example, when the top of the knob housing 4111 protrudes from the outer wall surface 31 of the control panel at the second height, it corresponds to the normal washing mode of the garment processing device 100; while when the top of the knob housing 4111 protrudes from the outer wall surface 31 of the control panel at the first height, it corresponds to the nighttime silent washing mode of the garment processing device 100.

[0085] Of course, the top of the knob housing 4111 can also protrude from the outer wall surface 31 of the control panel at a third height, a fourth height, etc., under the driving action of the drive component 43, so as to correspond to more types of adjustment modes of the clothing processing equipment 100.

[0086] In one alternative embodiment, please refer to Figure 4 , Figure 9 and Figure 10 The transmission assembly 42 includes a first transmission member 421 and a second transmission member 422. One end of the first transmission member 421 is connected to the knob assembly 41, and the other end is connected to one end of the second transmission member 422. The other end of the second transmission member 422 is connected to the drive assembly 43.

[0087] Under the driving action of the drive assembly 43, the second transmission component 422 transmits force sequentially to the first transmission component 421 and the knob assembly 41, so that the knob assembly 41 moves with the first transmission component 421 and the second transmission component 422.

[0088] In an optional embodiment, the transmission assembly 42 is a crank-rocker mechanism, the first transmission member 421 is a first transmission rod 4211, the second transmission member 422 is a second transmission rod 4221, the second transmission rod 4221 is driveably connected to the drive assembly 43, one end of the first transmission rod 4211 is driveably connected to the knob body 412, and the other end is rotatably connected to the second transmission rod 4221. The second transmission rod 4221 rotates under the drive of the drive assembly 43, thereby driving the first transmission rod 4211 to rotate.

[0089] Figure 9 The diagram shows the state of the first transmission rod 4211 and the second transmission rod 4221 when the distance from which the knob housing 411 protrudes from the outer wall of the control panel 32 is at its maximum stroke. Figure 10 The diagram shows the state of the first transmission rod 4211 and the second transmission rod 4221 when the knob housing 411 does not protrude from the outer wall of the control panel 32.

[0090] It should be noted that the transmission component 42 is not limited to a crank-rocker mechanism, but can also be a cam push rod mechanism, a lead screw transmission mechanism, a gear and rack mechanism, etc., which can push the knob component 41 out to protrude from the outer wall of the control panel 32 and retract it into the control panel 32.

[0091] In an alternative embodiment, please refer to 4 and Figure 11a The knob device 4 also includes a first guide component 44, which is disposed between the knob body 412 and the drive component 43. Under the guidance of the first guide component 44, the knob housing 411 moves along the first direction to protrude from the outer wall surface 31 of the control panel, or does not protrude from the outer wall surface 31 of the control panel.

[0092] By using the first guide component 44 to guide the knob component 41 during its movement, the stability of the knob component 41 when it is turned out of or retracted from the control panel 32 and the consistency of the direction of the knob component 41 during its movement can be ensured. Furthermore, the occurrence of collisions during the movement of the knob component 41 can be greatly reduced, ensuring the normal operation of the knob component 41.

[0093] In an alternative embodiment, such as Figure 11a and Figure 11b The first guide assembly 44 includes multiple guide rods 441 and guide holes 442 adapted to the guide rods 441. The multiple guide holes 442 are circumferentially distributed around the axis of the knob housing 411. The guide holes 442 are disposed on the knob body 412, and the guide rods 441 are disposed on the mounting member 45 (hereinafter referred to as the mounting member). The guide holes 442 move relative to the guide rods 441 as the knob assembly 41 moves. The axial directions of the guide rods 441 and the guide holes 442 are both in the first direction, that is, the axial direction of the knob housing 411, further ensuring the stability of the knob housing 411 during the extension and retraction process. The number of guide holes 442 matches the number of guide rods 441, and the number of guide holes 442 and guide rods 441 can be set according to the size of the knob assembly 41. This application embodiment does not make specific limitations.

[0094] In one alternative embodiment, please refer to Figures 11a to 13 The knob device 4 also includes a mounting member 45 and a second guide member 46.

[0095] Mounting component 45 is used to connect to control panel 32. Drive component 43 is installed on mounting component 45. Mounting component 45 is provided with mounting holes and mounting plate as required, and the specific shape of the mounting plate is set as required. This application embodiment does not make specific limitations.

[0096] The second guide member 46 has an annular structure. It is connected to the mounting member 45 and is sleeved around the knob housing 411. The inner wall of the second guide member 46 is provided with a plurality of guide ribs 461 extending along the first direction. The plurality of guide ribs 461 are circumferentially distributed around the axis of the second guide member 46 to guide the knob assembly 41.

[0097] Based on the guidance of the first guide component 44, the second guide component 46 is used for further guidance, which improves the consistency of the movement direction of the knob component 41, further ensures the stability of the knob component 41 when it is turned in and out, and improves the user experience.

[0098] In an optional embodiment, the second guide 46 is an independent component, and its material differs from that of the control panel 32. Since friction exists between the outer wall of the knob housing 411 and the inner wall of the second guide 46 due to relative movement, the second guide 46 is made of POM (polyoxymethylene). This reduces the friction between the knob housing 411 and the second guide 46, significantly reducing debris and fuzzing caused by long-term friction, while ensuring the guiding effect between them. The control panel 32 is made of ABS (acrylonitrile-butadiene-styrene copolymer). ABS is less expensive than the second guide 46, thus reducing the overall cost of the knob assembly 41.

[0099] In an optional embodiment, the second guide 46 and the control panel 32 are integrally formed by injection molding and both are made of POM material. This not only reduces the number of steps in the installation of the knob assembly 41, but also reduces the debris and fuzzing caused by long-term friction between the knob housing 411 and the second guide 46.

[0100] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this application that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this application and do not limit the scope of protection of this patent application.
