Description

Technical Field

[0001] This application relates to the field of kitchen equipment technology, and more particularly to a knob mounting assembly and cooking equipment. Background Technology

[0002] In kitchen appliances, the knob is the core component for user interaction with the device. It is usually connected to the internal control system of the appliance through a matching component such as an encoder or thermostat, and is used to perform key operations such as temperature adjustment and function switching.

[0003] In existing technologies, knobs are typically fixed to the panel through a multi-stage connection structure. Specifically, at least two transition pieces are introduced between the knob base and the panel and connected by threads: the first transition piece is fixed to the knob base by screws to form an intermediate assembly; the second transition piece engages with the first transition piece by threads or screws, ultimately fixing the intermediate assembly to the panel.

[0004] However, this structure, which relies on multiple transition parts and threaded connections, leads to problems such as redundant parts and cumbersome assembly steps. Summary of the Invention

[0005] This application provides a knob mounting assembly and cooking device to solve the problem that the installation of existing knobs relies on multiple transition parts and threaded connections, resulting in redundant parts and cumbersome assembly steps.

[0006] In a first aspect, this application provides a knob mounting assembly, comprising:

[0007] The panel has mounting holes and has a first surface and a second surface disposed opposite to each other.

[0008] A knob base is inserted through the mounting hole, and one end of the knob base is provided with an abutment portion, and the circumferential sidewall of the knob base is provided with an elastic buckle;

[0009] A limiting structure is provided to engage with the knob base to restrict the rotation of the knob base relative to the panel.

[0010] In the assembled state, the abutting part abuts against the first surface of the panel, and the elastic buckle engages with the second surface of the panel to jointly restrict the knob seat from moving along its axial direction.

[0011] As an optional implementation, the mounting hole is a non-circular hole, and the cross-sectional shape of the portion of the knob seat that passes through the mounting hole is adapted to the shape of the mounting hole, and the hole wall of the mounting hole constitutes the limiting structure.

[0012] As an optional implementation, the knob mounting assembly further includes a bracket fixed to the second surface of the panel, the bracket being provided with the limiting structure.

[0013] As an optional implementation, the bracket has a connection hole, which is a non-circular hole;

[0014] The knob seat passes through the connecting hole, and the cross-sectional shape of the portion of the knob seat passing through the connecting hole is adapted to the shape of the connecting hole. The hole wall of the connecting hole constitutes the limiting structure.

[0015] As an optional implementation, the bracket has a connecting hole, and the knob seat passes through the connecting hole;

[0016] The connecting hole has a guide protrusion on its wall and a guide groove on the side wall of the knob seat. The width of the guide groove decreases along the axial direction of the knob seat, and the guide protrusion slides into the guide groove.

[0017] The guide protrusion engages with the sidewall of the guide groove to form the limiting structure.

[0018] As an optional implementation, the resilient buckle has a side surface for preventing rotation;

[0019] The bracket is provided with a limiting groove;

[0020] In the assembled state, at least a portion of the elastic buckle is located within the limiting groove, and the side surface of the elastic buckle abuts against or is clearance-fitted with the groove wall of the limiting groove to restrict the rotation of the knob seat.

[0021] As an optional implementation, the end of the limiting groove facing the first surface of the panel is provided with a guide slope, which is used to guide the elastic buckle to slide into the limiting groove during assembly.

[0022] As an optional implementation, the side wall of the knob seat is provided with a clearance opening, and the elastic buckle is disposed in the clearance opening and can elastically deform into the clearance opening.

[0023] As an optional implementation, the elastic buckle includes:

[0024] A connecting arm, one end of which is connected to the side wall of the clearance opening away from the abutment portion;

[0025] A hook is attached to the other end of the connecting arm, the hook having a snap-fit ​​surface for snapping into the second surface of the panel;

[0026] In its natural state, the maximum outer diameter of the hook is greater than the diameter of the mounting hole.

[0027] Secondly, this application provides a cooking device, comprising:

[0028] Equipment body;

[0029] The knob mounting assembly of any of the above, wherein the panel of the knob mounting assembly is mounted on the device body;

[0030] A knob is mounted on the knob base of the knob mounting assembly.

[0031] This application provides a knob mounting assembly and cooking device. The knob mounting assembly includes a panel, a knob base, and a limiting structure. The panel has a mounting hole and has a first surface and a second surface arranged opposite to each other. The knob base passes through the mounting hole, and one end of the knob base has an abutment portion. The circumferential sidewall of the knob base has an elastic buckle. The limiting structure cooperates with the knob base to restrict the rotation of the knob base relative to the panel. In the assembled state, the abutment portion abuts against the first surface of the panel, and the elastic buckle engages with the second surface of the panel to jointly restrict the axial movement of the knob base. By directly mounting the knob base to the panel, the mounting structure is simplified. Specifically, the abutment portion at one end of the knob base abuts against the first surface of the panel, and the elastic buckle on the circumferential side directly engages with the second surface of the panel. The two work together to restrict the axial movement of the knob base. At the same time, the limiting structure, in cooperation with the knob base, effectively prevents the knob base from rotating. This knob mounting assembly eliminates the need for multiple transition parts and threaded connections required in traditional solutions. Installation can be completed simply by inserting the knob base into the panel mounting hole and locking it with elastic clips. This significantly reduces the number of parts, simplifies the assembly process, and effectively solves the technical problems of redundant parts and cumbersome assembly in knob installation.

Obviously, the described embodiments are only some embodiments of the embodiments of this application, and not all embodiments.

For those skilled in the art, the specific meaning of these terms in the embodiments of this application can be understood according to the specific circumstances.

[0059] Furthermore, the terms "set up," "connect," and "fix" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this disclosure according to the specific circumstances.

[0060] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the present application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0061] In this application, the terms "exemplarily" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplarily" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0062] As is known from the background art, the knobs of kitchen appliances are usually fixed to the panel through a multi-stage connection structure. Specifically, at least two transition pieces need to be introduced between the knob seat and the panel and connected by threads: the first transition piece is fixed to the knob seat by screws to form an intermediate assembly; the second transition piece cooperates with the first transition piece by threads or screws, finally fixing the intermediate assembly to the panel.

[0063] However, the above installation method relies on complex threaded connections and multi-part assembly, with a large number of parts and many structural layers, requiring multiple positioning and tightening, making the assembly process complex and time-consuming.

[0064] In view of the above, this application provides a knob mounting assembly and a cooking device. The knob mounting assembly includes a panel, a knob seat, and a limiting structure. The panel has a mounting hole and has a first surface and a second surface that are disposed opposite to each other. The knob seat passes through the mounting hole and has an abutment at one end. The circumferential sidewall of the knob seat has an elastic buckle. The limiting structure is used to cooperate with the knob seat to limit the rotation of the knob seat relative to the panel. In the assembled state, the abutment abuts against the first surface of the panel, and the elastic buckle engages with the second surface of the panel to jointly limit the axial movement of the knob seat.

[0065] The knob mounting assembly provided in this application simplifies the mounting structure by directly connecting the knob base to the panel. Specifically, the abutment portion at one end of the knob base abuts against the first surface of the panel, while the elastic buckle on its periphery directly engages with the second surface of the panel. Through the synergistic action of the abutment portion and the elastic buckle, the axial movement of the knob base is restricted, thereby completing the axial fixation of the knob base on the panel.

[0066] This design eliminates the need for multiple transitional plastic parts and corresponding screw connections required in existing technologies, significantly reducing the number of components. During assembly, simply insert the knob base into the mounting hole on the panel and lock it in place using the elastic clip; the assembly process is simplified to a one-step plug-in operation, greatly streamlining the assembly steps. Simultaneously, the limiting structure, in conjunction with the knob base, effectively restricts the rotation of the knob base relative to the panel; this anti-rotation function also does not rely on additional threaded fasteners.

[0067] Therefore, the knob mounting assembly of this application eliminates the need for traditional multi-level connection methods in terms of structure, and effectively solves the problems of redundant parts and cumbersome assembly steps in the knob installation process through highly integrated design.

[0068] The technical solution of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0069] Combination Figure 1 and Figure 2 As shown, the first aspect of this application provides a knob mounting assembly, including a panel 100 and a knob base 200.

[0070] The panel 100 has a mounting hole 101 and has a first surface 110 and a second surface 120 disposed opposite to each other. A knob base 200 passes through the mounting hole 101, and has an abutment portion 210 at one end. A resilient buckle 220 is provided on the circumferential side wall of the knob base 200. The knob base 200 has an internal cavity for accommodating the knob 400.

[0071] In the assembled state, the abutment portion 210 of the knob seat 200 abuts against the first surface 110 of the panel 100, while the elastic latches 220 on the periphery of the knob seat 200 engage with the second surface 120 of the panel 100. Through the combined action of the abutment portion 210 and the elastic latches 220 from both sides of the panel 100, the movement of the knob seat 200 along its own axial direction can be effectively restricted, thereby achieving axial fixation of the knob seat 200 on the panel 100.

[0072] Specifically, during installation, the end of the knob base 200 with the elastic buckle 220 can be aligned with the mounting hole 101 of the panel 100, and an axial thrust is applied in the direction from the first surface 110 toward the second surface 120. When the knob base 200 passes through the mounting hole 101, the elastic buckle 220 is squeezed by the wall of the mounting hole 101 and undergoes elastic deformation toward the center of the knob base 200, thus allowing it to pass smoothly through the mounting hole 101. After the elastic buckle 220 has completely passed through the mounting hole 101, it can return to its natural state due to its own elasticity, as it is no longer constrained by the hole wall. At this time, the engaging part of the elastic buckle 220 will hook onto the second surface 120 of the panel 100. At the same time, the abutting part 210 at the end of the knob base 200 remains in contact with the first surface 110 of the panel 100, forming a limit from the other side of the panel 100. In this way, the knob seat 200 is securely restricted in the thickness direction of the panel 100 by the cooperative action of the abutment part 210 and the elastic buckle 220, and cannot be dislodged in the axial direction.

[0073] After axial fixation is completed, the knob seat 200 may still rotate around its axis. To limit the rotation of the knob seat 200, the knob mounting assembly in this embodiment of the application also includes a limiting structure, which cooperates with a corresponding part of the knob seat 200. When the knob seat 200 attempts to rotate, the limiting structure will obstruct it, thereby locking the rotational degree of freedom of the knob seat 200.

[0074] By integrating the axial fixing function of the knob seat 200 into its own abutment part 210 and elastic buckle 220 structure, and using a limiting structure to achieve anti-rotation function, the multiple independent transition parts and threaded connection methods used for axial fixing and anti-rotation in traditional solutions are eliminated. During assembly, the knob seat 200 only needs to be inserted into the mounting hole 101 of the panel 100 until the elastic buckle 220 locks in to complete the installation, which significantly reduces the number of parts, simplifies the assembly process, and effectively solves the problems of redundant parts and cumbersome assembly in the existing knob 400 mounting structure.

[0075] Combination Figure 3 As shown, in some embodiments, the mounting hole 101 is a non-circular hole.

[0076] It should be noted that the non-circular hole here refers to a hole whose cross-sectional shape is not perfectly circular. For example, it can be elliptical, rectangular, D-shaped, or other shapes with at least one straight or discontinuous curvature sidewall.

[0077] Accordingly, the cross-sectional shape of the portion of the knob seat 200 that passes through the mounting hole 101 is adapted to the shape of the mounting hole 101. Thus, the outer contour shape of the knob seat 200 basically matches the inner contour shape of the mounting hole 101, preventing the knob seat 200 from rotating freely within the mounting hole 101.

[0078] With this configuration, the wall of the mounting hole 101 itself directly constitutes a limiting structure for restricting the rotation of the knob seat 200. When the knob seat 200 is assembled, its outer surface fits tightly against the wall of the mounting hole 101 in multiple locations or along a specific direction, or maintains a small clearance fit. Once the knob seat 200 is subjected to a rotational torque, its outer wall will abut against the wall of the mounting hole 101, thereby preventing further relative rotation.

[0079] Specifically, the knob mounting assembly provided in this application achieves its anti-rotation function through the direct fit between the panel 100 and the knob base 200, eliminating the need for additional independent parts to act as a limiting structure. The wall of the mounting hole 101 is both part of the structure of the panel 100 and serves as a limiting function, achieving a high degree of structural integration. During assembly, it is only necessary to ensure that the knob base 200 is aligned with the mounting hole 101 at a specific angle and inserted; once axially fixed, its rotational freedom is automatically locked. This solution greatly simplifies the overall structure, reduces the number of parts, and lowers assembly complexity.

[0080] Combination Figure 4 and Figure 5 As shown, in some other embodiments, the knob mounting assembly also includes a bracket 300, which is fixed to the second surface 120 of the panel 100, for example, by means of adhesive, snap-fit, welding or threaded connection.

[0081] Understandably, in actual production, especially when the panel 100 uses hard, brittle, or high-cost materials such as glass, machining non-circular, irregularly shaped mounting holes 101 on it is more difficult, requires higher precision, and is more expensive than machining simple circular holes. By introducing the bracket 300, a limiting structure can be provided for or supported to restrict the rotation of the knob seat 200. The mounting holes 101 on the panel 100 can then be set as standard circular holes, significantly reducing the machining difficulty and production cost of the panel 100, and improving production efficiency and yield.

[0082] Furthermore, considering that in many application scenarios, such as home appliance control panels 100, the inner side of the panel 100 typically already has a support structure for mounting displays, circuit boards, or other functional modules, the bracket 300 in this embodiment can be integrated with these existing internal support structures in its structural design. For example, the limiting structure can be directly set or formed on the existing display panel support structure, or the bracket 300 of this embodiment can be designed as an integral piece with the display panel support structure. This approach avoids adding extra independent parts, makes full use of the internal space of the device and the existing structure, and achieves functional integration and further cost optimization.

[0083] Specifically, by setting up a bracket 300 as a component independent of the panel 100 to support the function of the limiting structure, the knob seat 200, after passing through the circular mounting hole 101 of the panel 100, can directly engage with the limiting structure on the bracket 300, thereby restricting its rotation. With this arrangement, the axial fixing function is still achieved by the abutment portion 210 of the knob seat 200 and the elastic buckle 220 engaging with the panel 100, while the anti-rotation function is achieved by the bracket 300 and its limiting structure. This solution transfers the anti-rotation function from the panel 100 to the more easily manufactured and integrated bracket 300, providing greater flexibility and cost-effectiveness while ensuring functional reliability.

[0084] In some embodiments, the bracket 300 has a connection hole 301, which is a non-circular hole. Its cross-sectional shape can be, for example, a rectangle, a D-shape, a polygon, or a circle with a keyway, etc.

[0085] During assembly, the knob base 200 passes sequentially through the mounting hole 101 on the panel 100 and the connecting hole 301 on the bracket 300.

[0086] The cross-sectional shape of the knob seat 200 passing through the connecting hole 301 is adapted to the shape of the connecting hole 301. Thus, the outer contour of the knob seat 200 and the inner contour of the connecting hole 301 match each other in shape, so that the two cannot rotate relative to each other in the circumferential direction.

[0087] With this configuration, the wall of the connecting hole 301 on the bracket 300 directly constitutes a limiting structure that restricts the rotation of the knob seat 200. When the knob seat 200 is assembled, its outer surface is tightly fitted or maintains a small clearance fit with the wall of the connecting hole 301 in a specific direction. Once the knob seat 200 is subjected to a rotational torque, its outer wall will abut against the wall of the connecting hole 301, thereby effectively preventing the knob seat 200 from rotating relative to the bracket 300 and the panel 100.

[0088] By placing the non-circular holes requiring precise alignment to achieve the anti-rotation function on an independent bracket 300, the high cost and difficulty of directly machining irregular holes on glass, metal, and other panels 100 are solved, while maintaining the reliability of the anti-rotation function. During assembly, simply align the knob seat 200 with the connecting hole 301 on the bracket 300 at a specific angle and insert it to achieve axial fixation and rotational locking simultaneously. The structure is simple and assembly is convenient.

[0089] For example, the bracket 300 can be made of materials such as plastic that are easy to injection mold into complex shapes. The non-circular connection hole 301 and its hole wall limiting structure can be processed with high precision and low cost through one-time molding.

[0090] Combination Figure 5 and Figure 6 As shown, in some embodiments, the bracket 300 has a connection hole 301, and the knob seat 200 passes through the mounting hole 101 on the panel 100 and the connection hole 301 on the bracket 300 in sequence during assembly.

[0091] To achieve anti-rotation function and optimize the assembly process, this embodiment of the application provides a guide protrusion 310 on the wall of the connecting hole 301 of the bracket 300, and a corresponding guide groove 230 on the side wall of the knob seat 200. The guide groove 230 extends axially along the knob seat 200, and its width gradually decreases in the insertion direction of the knob seat 200, forming a tapered flared structure. During assembly, the guide groove 230 on the knob seat 200 and the guide protrusion 310 on the bracket 300 are aligned and slide together. Specifically, along the circumference of the knob seat 200, the guide groove 230 and the elastic buckle 220 are spaced apart.

[0092] When the knob seat 200 is pushed into the connection hole 301, the guide protrusion 310 slides along the tapered slope of the guide groove 230, so that the knob seat 200 can be automatically guided and aligned during the insertion process. Even if there are minor assembly deviations, they can be corrected by the guiding effect of the slope, thereby significantly improving the accuracy and smoothness of assembly.

[0093] Once the knob seat 200 is assembled, the guide protrusion 310 abuts against or closes to the side wall of the narrower end of the guide groove 230. At this point, if the knob seat 200 attempts to rotate, the guide protrusion 310 will immediately interfere with the side wall of the guide groove 230, effectively limiting its rotation. The guide protrusion 310 and the side wall of the guide groove 230 cooperate to form a limiting structure.

[0094] For example, symmetrically distributed guide grooves 230 can be provided on the outer side of the knob base 200, and corresponding guide protrusions 310 are provided on the bracket 300 to cooperate with them. Since these limiting feature structures on the knob base 200 and the bracket 300 are relatively small in size and regular in shape, their dimensional tolerances can be controlled within a small range during manufacturing (e.g., by injection molding). This precise fit can effectively ensure the stability of the knob 400 during rotation, avoid large shaking or gaps, and improve the operating feel and product quality.

[0095] In summary, the embodiments of this application integrate assembly guidance, rotation limit and motion precision control functions through the cooperation of guide protrusion 310 and tapered guide groove 230. While ensuring the reliable implementation of anti-rotation function, it simplifies assembly operation, improves assembly efficiency and precision, and also ensures a stable feel when using knob 400.

[0096] Combination Figure 7 and Figure 8 As shown, in some embodiments, a limiting groove 302 is provided on the bracket 300 fixed to the second surface 120 of the panel 100. Meanwhile, the elastic buckle 220 provided on the periphery of the knob seat 200 is further configured not only for axial locking but also for anti-rotation. Specifically, the elastic buckle 220 has a side surface 2221 for anti-rotation, which can be a plane or a curved surface of a specific shape.

[0097] In the assembled state, after the knob seat 200 passes through the mounting hole 101 of the panel 100 and its elastic buckle 220 engages with the second surface 120 of the panel 100, at least a portion of the elastic buckle 220 extends into or is located in the corresponding limiting groove 302 on the bracket 300. At this time, the side surface 2221 of the elastic buckle 220 forms an abutting or small-clearance fit with the groove wall of the limiting groove 302. When the knob seat 200 is subjected to a rotational torque, the side surface 2221 of the elastic buckle 220 will contact the groove wall of the limiting groove 302 and interfere, thereby effectively preventing the rotation of the knob seat 200. At this time, the groove wall of the limiting groove 302 constitutes a limiting structure.

[0098] For example, the bracket 300 may be provided with two limiting grooves 302, which correspond one-to-one with two elastic buckles 220 at different circumferential positions on the knob seat 200 and cooperate with each other. While performing the axial locking function, each elastic buckle 220's side surface 2221 works together with the groove wall of the corresponding limiting groove 302 to restrict the rotational freedom of the knob seat 200 around its axis.

[0099] Specifically, by using the axial fixing component (elastic snap 220) of the knob seat 200 as the anti-rotation component, and the limiting groove 302 on the bracket 300 as a simple mating structure, the need to add independent anti-rotation features to the knob seat 200 or the bracket 300 is avoided, effectively simplifying the component structure. During assembly, as the knob seat 200 is axially snapped and fixed, its elastic snap 220 automatically enters the limiting groove 302 of the bracket 300, thus realizing the anti-rotation function. No additional operating steps are required, resulting in a compact structure, fewer parts, and a clear and efficient assembly logic.

[0100] Combination Figure 8 and Figure 9 As shown, in some embodiments, the limiting groove 302 is provided with a guide slope 320 at one end facing the first surface 110 of the panel 100 (i.e. the end that the elastic buckle 220 of the knob seat 200 first approaches during assembly). The guide slope 320 is used to guide the elastic buckle 220 into the limiting groove 302 during assembly.

[0101] When an axial thrust is applied to the knob seat 200, its elastic latch 220 continues to move toward the bracket 300 after passing through the mounting hole 101 of the panel 100. The end or side of the elastic latch 220 first contacts the guide ramp 320 at the entrance of the limiting groove 302. Under the continuous action of the axial thrust, the elastic latch 220 will slide along the guide ramp 320 and be guided by the component force generated by the ramp, thereby smoothly and accurately sliding into the predetermined position inside the limiting groove 302.

[0102] The guide ramp 320 can compensate for minor alignment deviations that may occur during assembly. Even if the knob seat 200 and the limiting groove 302 on the bracket 300 are not perfectly aligned initially, the elastic buckle 220 can automatically adjust its position and smoothly enter the groove under the guidance of the ramp. This reduces the stringent requirements for assembly precision, making the assembly operation easier and faster, optimizing the assembly experience, and effectively avoiding assembly difficulties or part damage caused by direct collision between the elastic buckle 220 and the opening of the limiting groove 302.

[0103] By setting the guide ramp 320, the smoothness and reliability of assembly are significantly improved without increasing manufacturing costs. The guide ramp 320 allows the knob seat 200 to complete the axial locking and fixation, while its elastic buckle 220 can more reliably complete the anti-rotation engagement with the upper limit groove 302 of the bracket 300, ensuring the stable realization of the anti-rotation function and further improving the practicality and manufacturability of the entire mounting assembly.

[0104] It should be noted that this application provides various specific implementation methods for achieving centralized anti-rotation function through the bracket 300. These implementation methods are not mutually exclusive or must be used alone. Those skilled in the art can combine any two or more methods according to specific product design requirements, cost control objectives, and different requirements for anti-rotation strength and assembly processes to achieve synergistically enhanced anti-rotation effects or meet specific functional integration requirements.

[0105] For example, the bracket 300 may simultaneously have a non-circular connecting hole 301, and a limiting groove 302 is provided around the connecting hole 301. When the knob seat 200 is inserted, its main body cooperates with the non-circular hole to achieve the main anti-rotation, while the elastic buckle 220 on it is engaged in the limiting groove 302, which not only provides the tactile feel of axial locking, but also achieves auxiliary anti-rotation or anti-shaking by cooperating with the side surface 2221 of the elastic buckle 220 and the groove wall of the limiting groove 302.

[0106] Alternatively, the connecting hole 301 of the bracket 300 is circular, with a guide protrusion 310 on the hole wall, and the bracket 300 also has an independent limiting groove 302. When assembling the knob seat 200, it is first smoothly guided into place by the cooperation of the guide protrusion 310 and the guide groove 230 to achieve basic anti-rotation; at the same time, the elastic buckle 220 of the knob seat 200 also slides into the independent limiting groove 302. Through the cooperation of the side surface 2221 of the elastic buckle 220 and the limiting groove 302, an additional anti-rotation function is provided, which is suitable for scenarios with extremely high requirements for rotational accuracy.

[0107] Alternatively, the connecting hole 301 of the bracket 300 is non-circular, and the inner wall of the hole is also provided with a guide protrusion 310. The bracket 300 is also provided with a limiting groove 302. This configuration can provide multi-level and multi-dimensional rotational constraints, ensuring the stability of the knob seat 200 under complex stress environments to a greater extent, while also having excellent assembly guidance and clear locking feedback.

[0108] Combination Figure 10 As shown, in some embodiments, a clearance opening 201 is provided on the side wall of the knob seat 200. The clearance opening 201 communicates with the receiving cavity inside the knob seat 200 for accommodating the knob 400. An elastic buckle 220 is disposed within the clearance opening 201, with one end connected to the main body of the knob seat 200 and the other end being a free end or elastically connected to the main body, so that the entire elastic buckle 220 can elastically deform into the interior space of the clearance opening 201 within its plane.

[0109] During assembly, when the knob seat 200 passes through the mounting hole 101 on the panel 100, the free end of the resilient snap fastener 220 contacts the wall of the mounting hole 101. With the continuous axial thrust, the wall of the mounting hole 101 applies a radially inward compressive force to the resilient snap fastener 220. Because the clearance opening 201 provides space for the resilient snap fastener 220 to deform inward, the resilient snap fastener 220 can retract into the clearance opening 201, thereby reducing its overall profile size to allow it to pass smoothly through the relatively small-diameter mounting hole 101.

[0110] Once the elastic buckle 220 has completely passed through the mounting hole 101, the radial compressive force exerted on the elastic buckle 220 by the hole wall of the mounting hole 101 disappears. At this time, the elastic restoring force of the elastic buckle 220's own material causes its free end to pop outward, returning to its initial or near-initial state. At this time, the snap-fit ​​surface 2222 of the elastic buckle 220 facing the abutment portion 210 will hook onto the second surface 120 of the panel 100, achieving axial locking.

[0111] The design of the clearance opening 201 not only provides the necessary space for the elastic deformation of the elastic snap 220, ensuring the feasibility of assembly, but also helps to control the deformation and stress distribution of the elastic snap 220, improving its service life and reliability. At the same time, integrating the elastic snap 220 into the clearance opening 201 on the side wall of the knob seat 200 results in a compact structure, requiring no additional parts, and facilitating rapid axial installation of the knob seat 200.

[0112] Combination Figure 10 As shown, in some embodiments, the resilient buckle 220 includes a connecting arm 221 and a hook 222.

[0113] One end of the connecting arm 221 is connected to the side wall of the clearance opening 201 away from the abutment portion 210, which can be welded or integrally formed. The connecting arm 221 has a certain length and elasticity, and its other end is connected to the hook 222.

[0114] The latch 222 is the part used to directly perform the locking function. The latch 222 extends from the end of the connecting arm 221 and has a latching surface 2222 for engaging with the second surface 120 of the panel 100. The latching surface 2222 faces the abutment portion 210 of the knob seat 200.

[0115] In its natural state (i.e., in a free state without external force), the diameter of the circumscribed circle formed by the outermost edge of the hook 222 is larger than the diameter of the mounting hole 101 on the panel 100.

[0116] Because the initial size of the hook 222 is larger than that of the mounting hole 101, it is squeezed by the wall of the mounting hole 101 during assembly. This causes the connecting arm 221 to elastically deform the hook 222 into the clearance opening 201, thus allowing the knob seat 200 to pass through. Once the hook 222 has completely passed through the mounting hole 101 and its size has returned to normal, the snap-fit ​​surface 2222 hooks onto the second surface 120 of the panel 100, working in conjunction with the abutment portion 210 at the other end to complete axial fixation, preventing the mounting seat from exiting the mounting hole 101.

[0117] The connecting arm 221 and the latch 222 form a cantilever beam structure, providing good elastic deformation capacity and sufficient locking force. The length and cross-sectional shape of the connecting arm 221 determine the elastic performance of the elastic latch 220, while the shape of the latch 222 and the angle of the engaging surface 2222 affect the reliability of locking and the ease of disassembly. By separating the elastic deformation function and the locking function into different parts, each part can be optimized for its function, ensuring reliable locking while achieving a smooth assembly feel.

[0118] In some embodiments, the elastic buckle 220 may employ a multi-stage elastic deformation structure. Specifically, the elastic buckle 220 may consist of at least two elastic segments with different stiffnesses (not shown in the figure). For example, it may include an outer high-stiffness segment (which may be reinforced with high-hardness plastic or composite metal material) near the hook 222 and an inner low-stiffness segment (which may be made of a more resilient elastomeric material) near the root of the connecting arm 221.

[0119] During assembly, when the knob seat 200 is pushed into the mounting hole 101 of the panel 100, the resilient snap 220 first deforms through its inner low-stiffness section, adapting to the hole wall of the mounting hole 101 with low resistance, achieving initial guidance and cushioning. As insertion proceeds further, the outer high-stiffness section begins to participate in deformation and provides the final, stronger radial locking force, ensuring that the hook 222 reliably engages with the second surface 120 of the panel 100.

[0120] The aforementioned multi-stage deformation method can better accommodate mounting holes 101 of the panel 100 with different thicknesses or minor manufacturing tolerances. Furthermore, the staged deformation avoids excessive stress concentration in localized areas of the elastic clip 220, effectively reducing the risk of material fatigue and extending the service life of the elastic clip 220. In addition, the initial low-stiffness deformation makes installation smoother, while the final high-stiffness locking ensures the axial stability of the knob seat 200 under vibration and other environmental conditions.

[0121] In some embodiments, a meshing tooth structure (not shown) may be provided on the sidewall of the knob seat 200 and / or on the sidewall of the connection hole 301 of the bracket 300. These meshing teeth may be distributed circumferentially.

[0122] Once the knob seat 200 is assembled, its meshing teeth engage with the corresponding teeth on the bracket 300 to restrict the circumferential rotation of the knob seat 200. For ease of assembly, a chamfered structure can be provided at the tooth inlet to achieve self-aligning engagement.

[0123] In some embodiments, a permanent magnet or a magnetic coating (not shown) is embedded in the bottom or sidewall of the guide groove 230 of the knob seat 200 and / or on the corresponding guide protrusion 310 of the bracket 300.

[0124] During assembly, when the knob base 200 approaches the bracket 300, the magnetic attraction function comes into play, automatically guiding the limiting structure on the knob base 200 to align with the limiting structure on the bracket 300, thus providing auxiliary positioning. After assembly, the magnetic attraction, in addition to the mechanical fit, provides extra auxiliary holding force, making the connection between the knob base 200 and the bracket 300 more stable.

[0125] This design is suitable for automated production lines or blind assembly scenarios, reducing alignment accuracy requirements and assembly adjustment time. Simultaneously, the magnetic assist enhances the overall reliability of the limiting mechanism, effectively resisting vibration and accidental impacts.

[0126] A second aspect of this application provides a cooking device, including but not limited to an oven, steamer, microwave oven, or induction cooker. The cooking device includes a device body, a knob mounting assembly as described in any of the above embodiments, and a knob 400.

[0127] The specific structure, connection relationship and technical effect of the knob mounting component have been described in detail in the above embodiments, and will not be repeated here.

[0128] The panel 100 of the knob mounting assembly is fixedly mounted on the housing of the device body, for example, in the control panel 100 area of ​​the device.

[0129] The knob 400 is mounted on the knob base 200 of the knob mounting assembly for user operation. The connection between the knob 400 and the knob base 200 can be achieved through various methods such as snap-fit, threaded connection, adhesive bonding, or fastening.

[0130] For example, the knob base 200 can be used to drive the shaft of an encoder 500 (or potentiometer) to adjust the electrical signal. The installation process is as follows: First, the knob base 200 is connected and secured to the housing or mounting part of the encoder 500 using, for example, two fixing screws. Then, the knob 400 (which typically has an internal connecting structure) is connected to the connecting rod (i.e., the shaft) of the encoder 500, thus completing the installation of the entire push-button and / or rotary knob 400 assembly. When the user presses or rotates the knob 400, the operating force is transmitted to the encoder 500 through the knob base 200, realizing the preset electrical control function.

[0131] The cooking equipment provided in this application embodiment, by adopting the knob mounting component in the above embodiment, can make the control panel 100 area have a simple appearance, the knob 400 be installed firmly and reliably without shaking, have excellent operating feel, and have high overall assembly efficiency and effectively control production costs.
