[0043] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, various possible combinations of the specific technical features in the present invention will not be described separately.

[0045] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the specific corresponding schematic diagrams, which may be the left and right directions in normal use or not.

[0046] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0047] The present application embodiment provides a knob assembly 1, please refer to the following Figure 1 , Figure 3 and Figure 4 , including an electric control component 13, a metal ring 111 and a transmission structure 12.

[0048] The user may hold the metal ring 111 and drive the metal ring 111 to rotate.

[0049] The metal ring 111 is directly or indirectly connected to the transmission structure 12, and the transmission structure 12 is used to rotate with the metal ring 111 to trigger the electric control component 13 to generate an electrical signal. In other words, the transmission structure 12 is a passive component, and the metal ring 111 rotates, which drives the transmission structure 12 to rotate together. When the transmission structure 12 rotates with the metal ring 111, the transmission structure 12 triggers the electric control component 13 to generate an electrical signal.

[0050] In the related art, the knob is made of plastic as a whole, and a damping structure is set at the rotation center of the knob to obtain a damping feel. However, the damping force arm is small at the rotation center, and a significant damping force needs to be set to obtain the damping feel. In addition, the friction resistance of the knob during rotation is relatively large, and the components are prone to wear. When the wear of the components reaches a certain level, the damping feel will be reduced or even disappear.

[0051] Compared with plastic parts of the same size, the knob assembly 1 of the embodiment of the present application has a metal ring 111 with a higher density and a heavier weight, which can give people a thicker feel and enhance the user experience; in addition, the heavy feel is obtained by the weight of the metal ring 111 itself, and no friction damping is required, which reduces the wear of components and increases the service life of the knob assembly 1.

[0052] See also Figure 6 , the circumferential outer surface of the metal ring 111 has a pattern structure area 1111, for example, knurling, and the pattern structure area 1111 is arranged along the circumference of the metal ring 111. In some embodiments, the circumferential arrangement of the pattern structure area 1111 along the metal ring 111 means extending along the circumference of the metal ring 111 from a starting point of the metal ring 111 until returning to the above starting point, that is, in this embodiment, the pattern structure area 1111 is continuous and arranged on the entire axial surface of the metal ring 111. In other embodiments, the circumferential arrangement of the pattern structure area 1111 along the metal ring 111 may be discontinuous, for example, two or more discontinuous pattern structure areas 1111 are arranged along the circumference of the metal ring 111.

[0053] It should be noted that the area where the pattern structure is located forms the pattern structure area 1111. The pattern structure refers to an uneven structure. The process for processing the pattern structure is not limited. For example, the knurling process is used to process the knurling, and the knurling belongs to the pattern structure. The pattern structure can increase the friction when the user's hand contacts the metal ring 111, reduce the probability of finger slippage, and improve the hand feel. In addition, it can also play a good aesthetic role.

[0054] The ratio of the depth of the pattern structure of the pattern structure area 1111 to the maximum wall thickness of the metal ring 111 is 0.03-0.5, for example, 0.03, 0.05, 0.08, 0.1, 0.2, 0.3, 0.4, 0.5, etc. The maximum wall thickness of the metal ring 111 refers to the thickness of the thickest part of the metal ring 111 along the radial direction.

[0055] The depth of the pattern structure refers to the radial dimension of the pattern structure along the metal ring 111 .

[0056] In this embodiment, the inventor found that the radial thickness of the metal ring 111 can make the metal ring 111 have a suitable structural strength and is not easy to deform during the processing of the pattern structure. For example, in order to obtain a greater friction feel, the depth of the pattern area is usually deepened in the related art. However, the inventor found that during the pattern processing, the setting of an overly deep pattern area requires a greater processing pressure, which will cause the metal ring to deform. In addition, the increase in the pattern depth will cause a stinging effect on the user's hand. Therefore, the inventor found that the appropriate depth of the pattern structure makes the pattern have a better look and feel, while also taking into account the requirements for the structural strength of the metal ring.

[0057] In some preferred embodiments, the ratio of the depth of the pattern structure of the pattern structure area 1111 to the maximum wall thickness of the metal ring 111 is 0.06-0.3, for example, 0.06, 0.08, 0.1, 0.2, 0.3, etc.

[0058] For example, see Fig. 9The depth of the pattern structure in the pattern structure area is 0.2 mm to 1.0 mm, for example, 0.2 mm, 0.24 mm, 0.28 mm, 0.3 mm, 0.4 mm, 0.43 mm, 0.45 mm, 0.48 mm, 0.5 mm, 0.55 mm, 0.6 mm, 0.62 mm, 0.65 mm, 0.7 mm, 0.74 mm, 0.75 mm, 0.8 mm, 0.83 mm, 0.86 mm, 0.9 mm, 0.91 mm, 0.95 mm, 1.0 mm, etc. Moreover, the maximum wall thickness of the metal ring is 1.5 mm to 6 mm, for example, 1.5 mm, 1.8 mm, 2 mm, 2.2 mm, 2.5 mm, 3 mm, 3.3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, etc.

[0059] For example, see Figure 7 The single pattern structure has a contact plane 1111a along the radial outer side of the metal ring 111, and the area of ​​the contact plane 1111a is 0.5mm 2 ~1.5mm 2 , for example, 0.5mm 2 , 0.6mm 2 , 0.7mm 2 , 0.8mm 2 , 0.9mm 2 , 1.0mm 2 , 1.1mm 2 , 1.2mm 2 , 1.3mm 2 , 1.4mm 2 , 1.5mm 2 In this embodiment, when the user touches the metal ring 111, the contact plane 111a has an appropriate area, so that the pattern structure area 1111 is smoother as a whole, which alleviates or even almost eliminates the prickly touch feeling, thereby improving the user experience.

[0060] Exemplarily, a coating is provided on the surface of the metal ring 111. The coating may have good glossiness, improving the aesthetic appearance of the metal ring. In some embodiments, the coating may also have the function of preventing corrosion and rust.

[0061] The material of the metal ring 111 is not limited, for example, the metal ring 111 is a zinc alloy component or an aluminum alloy component. In other words, the material of the metal ring 111 can be a zinc alloy or an aluminum alloy. In this embodiment, the zinc alloy or the aluminum alloy has good machining performance, which can facilitate the processing of the above-mentioned deep pattern structure, and has suitable structural strength and good deformation resistance performance.

[0062] In some preferred embodiments, the metal ring 111 is a zinc alloy component. The density of zinc alloy is relatively large, which can make the metal ring 111 have a heavy feel with a suitable weight.

[0063] Exemplarily, the weight of the metal ring 111 is 20 g to 100 g, for example, 20 g, 30 g, 40 g, 50 g, 60 g, 70 g, 80 g, 90 g, 100 g, etc. The weight of the metal ring 111 can make the metal ring 111 have a good thick feel and better conform to ergonomics.

[0064] For example, see Figure 2 The outer diameter D of the metal ring 111 is 30 mm to 100 mm, that is, 30 mm ≤ D ≤ 100 mm. For example, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, etc. This outer diameter size range is convenient for human hands to hold, conforms to ergonomics, and improves user experience.

[0065] The area between the edge of at least one side of the pattern structure area 1111 along the axial direction and the axial end face of the metal ring 111 has a blank area (such as the first blank area 111da and / or the second blank area 111db hereinafter) without knurling. In this embodiment, during the processing of the pattern structure, the processing tool maintains a certain distance from the axial end face of the metal ring 111, and the pattern structure will not be processed within the distance range, that is, the blank area is formed, which can play a mechanical protection role for the axial end of the metal ring 111 and reduce the probability of cracking or plastic deformation of the axial end of the metal ring 111. In addition, the blank area can also reduce the probability of the pattern structure area 1111 scratching the user's hand at the edge.

[0066] For example, see Figure 8 A chamfer structure 1112 is provided on the circumferential outer side of at least one axial end of the metal ring 111, and the chamfer structure 1112 is located in the blank area. The chamfer structure 1112 makes the axial end of the metal ring 111 smoother without forming sharp corners, thereby reducing the chance of scratching the user's hand.

[0067] It should be noted that a blank area may be provided on any axial side of the pattern structure area 1111. Blank areas may also be provided on both axially opposite sides of the pattern structure area 1111, so that the metal ring 111 can be better protected during the processing and the user's hand can be better protected.

[0068] For example, see Figure 4 and Figure 8In the embodiment where blank areas are provided on both axially opposite sides of the pattern structure area 1111, for the convenience of description, the blank area on the side of the pattern structure area 1111 away from the electronic control component 13 is recorded as the first blank area 111da, and the blank area on the other side is recorded as the second blank area 111db.

[0069] The first blank area 111da is the side close to the user.

[0070] The sizes of the first blank area 111da and the second blank area 111db along the axial direction may be the same or different.

[0071] For some examples, see Fig. 9 , the length L3 of the first blank area 111da along the axial direction is greater than the length L4 of the second blank area 111db along the axial direction. Since the second blank area 111db is on the side away from the user, the length of the second blank area 111db along the axial direction can be appropriately shorter, while the first blank area 111da is close to the user and can be appropriately longer to have a better hand feel and appearance.

[0072] For example, see Fig. 9 , the ratio of the length L1 of the pattern structure area 1111 along the axial direction to the length L2 of the metal ring 111 along the axial direction is 30% to 90%, that is, 30%≤L1 / L2≤90%. For example, 30%, 40%, 50%, 60%, 70%, 80%, 90%, etc. In this embodiment, the pattern structure area 1111 has a relatively long length. When the user holds the metal ring 111, the pattern structure can be contacted in a large range, reducing the probability of slipping.

[0073] In some preferred embodiments, 50%≤L1 / L2≤80%.

[0074] Exemplarily, the length L2 of the metal ring 111 along the axial direction is 7 mm to 20 mm, for example, 7 mm, 8 mm, 9 mm, 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, 20 mm, etc.; the length of the blank area along the axial direction is not less than 1 mm, that is, the length of the blank area along the axial direction on any side is not less than 1 mm; the length L1 of the pattern structure area 1111 along the axial direction is not less than 5 mm. In this embodiment, the blank area has a suitable length, and the pattern structure area 1111 can also have an appropriate distance from the axial end face of the metal ring 111. The length of the pattern structure area 1111 is more ergonomic and meets the needs of human fingers for gripping.

[0075] In some embodiments, the length L3 of the blank area along the axial direction is 1 mm to 3 mm, for example, 1 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2 mm, 2.3 mm, 2.7 mm, 3 mm, etc. In this embodiment, the length of the blank area along the axial direction is appropriate to protect the user's hand.

[0076] In some embodiments, the length L1 of the pattern structure area 1111 along the axial direction is 5 mm to 17 mm, for example, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, etc. In this embodiment, the length of the pattern structure area 1111 along the axial direction is appropriate, which is convenient for users to hold and reduces the probability of slipping.

[0077] The metal ring 111 may be directly or indirectly connected to the transmission structure 12 .

[0078] For example, in some embodiments, please refer to Figure 4 , Figure 5 and Figure 6 The knob assembly 1 includes a connection structure 112 disposed radially inwardly of the metal ring 111, and the connection structure 112 is a plastic part that is injection molded on the inner side of the metal ring 111. That is, the metal ring 111 and the connection structure 112 are injection molded into an integrated structure. For example, during the manufacturing process, after the metal ring 111 is processed, the metal ring 111 is placed in an injection mold, and molten resin is injected into the injection mold. After the mold is opened, the resin is cooled to form the above-mentioned connection structure 112, and the resin and the metal ring 111 are combined together without the need for other fasteners for connection.

[0079] In this embodiment, the connection structure 112 is connected to the transmission structure 12, and there is no need to process the connection structure 112 that meets the assembly accuracy requirements on the metal ring 111, which can reduce the manufacturing requirements for the metal ring 111, save materials, and reduce costs. It is only necessary to manufacture the connection structure 112 into a designed shape. Therefore, the knob assembly 1 of the embodiment of the present application has a heavy feel while taking into account the manufacturing cost and process.

[0080] The specific connection method between the connection structure 112 and the transmission structure 12 is not limited.

[0081] Exemplarily, one of the transmission structure 12 and the connection structure 112 is provided with a plurality of slots 12a (see Fig.10 ), and the other is provided with a plurality of hooks 1122 (see Figure 6), a plurality of hooks 1122 are arranged along the circumference of the ring body 111, and the hooks 1122 are snapped into the slots 12a. For example, in some embodiments, the transmission structure 12 is provided with hooks 1122, and the connecting structure 112 is provided with slots 12a. In other embodiments, the transmission structure 12 is provided with slots 12a, and the connecting structure 112 is provided with hooks 1122. In still other embodiments, the transmission structure 12 is provided with a portion of hooks 1122 and a portion of slots 12a, and the connecting structure 112 is provided with another portion of hooks 1122 and another portion of slots 12a, the hooks 1122 on the connecting structure 112 are snapped into the slots 12a on the transmission structure 12, and the slots 12a on the connecting structure 112 are snapped into the hooks 1122 on the transmission structure 12.

[0082] In this embodiment, the hook 1122 and the slot 12a cooperate to achieve quick connection without the need for special tools, and the assembly is simple and fast.

[0083] In some embodiments, in the embodiment where the ring body 111 and the connecting structure 112 are injection molded into an integral structure, please refer to Figure 6 and Figure 8 The ring body 111 is provided with a receiving groove 111a, and at least a part of the connecting structure 112 is filled in the receiving groove 111a. The receiving groove 111a can increase the contact area and bonding strength between the plastic and the metal, and reduce the probability of the connecting structure 112 and the ring body 111 being loosened along the axial direction.

[0084] The specific shape of the receiving groove 111 a is not limited.

[0085] For example, see Figure 6 and Figure 8 , the receiving groove 111a is an annular groove surrounding the ring body 111, that is, the receiving grooves 111a are connected end to end, and the central angle of the receiving groove 111a is 360°. The connecting structure 112 includes a connecting ring 1121, and the connecting ring 1121 is filled in the annular groove. During the injection molding process, the molten resin poured into the receiving groove 111a forms the connecting ring 1121 after cooling and molding. In this embodiment, the structural form of the connecting ring 1121 can enhance the structural strength of the connecting structure 112, and the reliability is higher.

[0086] It is understandable that when the connection structure 112 is provided with a slot 12a, the slot 12a may be formed on the connection ring 1121. When the connection structure 112 is provided with hooks 1122, each hook 1122 is connected to the connection ring 1121.

[0087] For example, see Figure 6 and Figure 8The groove wall of the ring groove along the radial side of the ring body 111 is provided with a spiral groove 111b, the spiral groove 111b extends spirally in the direction surrounding the groove wall, and a part of the connecting ring 1121 is filled in the spiral groove 111b. The spiral groove 111b can further strengthen the injection molding bonding strength of plastic and metal and improve reliability.

[0088] It should be noted that the dimension of the spiral groove 111b along the axial direction of the ring body 111 is smaller than the dimension of the annular groove along the axial direction. For example, the dimension of the spiral groove 111b along the axial direction of the ring body 111 is 1 / 3 to 1 / 6 of the dimension of the annular groove along the axial direction.

[0089] Exemplarily, the radial dimension of the spiral groove 111 b along the ring body 111 is smaller than the radial dimension of the annular groove, so as to reduce the influence of the spiral groove 111 b on the structural strength of the ring body 111 .

[0090] For example, see Figure 8 , any one of the groove walls of the annular groove is provided with at least one recess 111c, and at least a portion of the connecting ring 1121 is filled in the recess 111c. For example, the recess 111c is provided on the axial side wall of the annular groove and / or the radial side wall of the annular groove. Figure 6 The structure filled in the pit 111c forms a protrusion 11211, and the cooperation between the protrusion 11211 and the pit 111c can prevent the connection structure 112 and the ring body 111 from rotating relative to each other. It should be noted that during the injection molding process, the molten resin poured into the pit 111c can form the protrusion 11211 after cooling and molding.

[0091] The number of the pits 111c is not limited, and may be one, or two or more.

[0092] For example, see Figure 1 and Figure 3 The knob assembly 1 includes a window cover 14, which is disposed in the metal ring 111 and remains relatively stationary with the electric control assembly 13. In other words, the metal ring 11 will not drive the window cover 14 to rotate, and during the rotation of the metal ring 11, the metal ring 11 and the window cover 14 have relative motion.

[0093] The material of the window cover 14 is not limited, for example, it can be light-transmitting plastic.

[0094] For example, see Figure 3 The knob assembly 1 includes a display assembly 15 , which is disposed inside the metal ring 111 and located on a side of the window cover 14 facing the electric control assembly 13 . In other words, the metal ring 111 surrounds the display assembly 15 .

[0095] The display assembly 15 is used to display information; the window cover 14 is used to see through the information displayed by the display assembly 15 .

[0096] The type of information displayed by the display component 15 is not limited, for example, it can be text, patterns, symbols, etc., which are not limited here.

[0112] For example, the user selects the corresponding washing program and washing parameters by rotating the metal ring 11. Specifically, taking the selection of the washing program as an example, when the user rotates the metal ring 11, it rotates at different angles, and the electronic control component 13 generates different electrical signals. Different electrical signals correspond to different washing programs. The control device controls the clothing processing equipment to enter the corresponding washing program according to the different electrical signals.

[0113] For example, see Fig.11 , Fig.12 and Fig.13 The housing includes a box body and a control panel 2, and the control panel 2 is arranged on the box body. For example, the top side of the front plate of the box body has a vacancy, and the control panel 2 is arranged in the vacancy.

[0114] See also Fig.13 , the control panel 2 is partially recessed toward the inside of the housing to form a recessed cavity 2a, the electric control component 13 is disposed in the recessed cavity 2a, and the metal ring 11 covers the recessed cavity 2a. In other words, the projection area of ​​the metal ring 11 on the panel of the control panel 2 covers the projection area of ​​the recessed cavity 2a, and the user can hardly see the recessed cavity 2a.

[0115] It can be connected that the cavity wall of the recessed cavity 2a is provided with a through hole 2b for passing the cable of the electric control component 13.
