[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0036] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0037] Hereinafter, with reference to the accompanying drawings, a knob assembly 100 for a cooking utensil 200 according to an embodiment of the present invention will be described.

[0038] like Figures 1-3As shown, the knob assembly 100 includes an encoder 1 and a knob 2. The encoder 1 includes an encoder rotating part 11 and an encoder fixing part 12. The encoder rotating part 11 is rotatable relative to the encoder fixing part 12. The knob 2 is fixedly connected to the encoder rotating part 11, and the knob 2 includes a decorative part 21. The surface of the decorative part 21 facing away from the encoder 1 and the outer peripheral wall of the decorative part 21 both help to define the outer surface of the knob 2. The decorative part 21 covers the axial outer end of the encoder rotating part 11.

[0039] As can be seen, the knob 2 is fixed relative to the encoder rotating part 11. The knob 2 can be rotated by the user. When the user rotates the knob 2, it drives the encoder rotating part 11 to rotate relative to the encoder fixed part 12, thereby enabling the encoder 1 to recognize and process commands for adjustment. Furthermore, this knob assembly 100 has a simple structure and is easy to process and manufacture. The structure and operation of the encoder 1 are well known to those skilled in the art and will not be described in detail here. As an example, the encoder 1 may also have a circuit board, which can be fixed relative to the encoder fixed part 12.

[0040] The specific structural forms of the encoder rotating part 11 and the encoder fixed part 12 are not limited. They can be fitted together in an inner and outer manner or in other forms, which will not be elaborated here. It is only necessary to ensure that the encoder rotating part 11 can rotate relative to the encoder fixed part 12.

[0041] Furthermore, since both the surface of the decorative element 21 facing away from the encoder 1 and the outer peripheral wall of the decorative element 21 contribute to defining the outer surface of the knob 2, the outer surface of the knob 2 includes the surface of the decorative element 21 facing away from the encoder 1 and the outer peripheral wall of the decorative element 21. The decorative element 21 covers the axial outer end of the encoder rotating part 11. Therefore, in the cross-section of the knob assembly 100, the orthographic projection of the axial outer end of the encoder rotating part 11 lies within the orthographic projection range of the decorative element 21. The decorative element 21 has a relatively large volume, making it convenient for the user to hold and rotate. When the knob assembly 100 is used in the cooking appliance 200, the decorative element 21 can be exposed in the body 101 of the cooking appliance 200 so that the user can identify the position of the knob 2. The decorative element 21 is transparent, while other structures of the cooking appliance 200 are generally not transparent. This design facilitates users' quick and easy differentiation between the decorative element 21 and other structures of the cooking appliance 200, enabling them to quickly locate the knob 2 and improving operational convenience and efficiency. Simultaneously, the translucency of the decorative element 21 facilitates the functional expansion of the knob 2, allowing for integration with other electronic components of the knob assembly 100 to achieve more intelligent interaction. For example, the light emitted by the light-emitting unit can pass through the decorative element 21 and be observed by the user. If the light-emitting unit can emit light of different colors and / or different flashing frequencies, the user can quickly determine the operating status of the cooking appliance 200 based on the aforementioned light signals. For instance, the higher the heat of the cooking appliance 200, the brighter the light from the light-emitting unit; conversely, the less cooking time remaining in the cooking appliance 200, the faster the light-emitting unit flashes.

[0042] Furthermore, when the knob assembly 100 is used in the cooking appliance 200, the knob 2 is usually exposed on the body 101 of the cooking appliance 200. Therefore, the knob 2 can reflect the brand image in terms of appearance and performance. Currently, most knobs in cooking appliances on the market are made of metal, plastic, and other materials, resulting in poor brand recognition. Moreover, metal and plastic materials are difficult to integrate with lighting; even when integrated, they are primarily backlit, limiting the expansion of knob functions and resulting in a single knob effect. In this embodiment, by including a decorative element 21 on the knob 2, with the surface of the decorative element 21 facing away from the encoder 1 and its outer peripheral wall both defining the outer surface of the knob 2, it is easier for users to quickly identify the position of the knob 2. This also breaks the limitations of integration with other electronic components such as lighting, allowing users to see the light passing through the decorative element 21 from the front of the knob 2. This expands the function and enriches the effect of the knob 2, effectively distinguishing it from other cooking appliances 200 on the market and enhancing brand recognition. Moreover, the knob assembly 100 is transparent or semi-transparent in appearance, with a relatively transparent overall structure and a simple structure, giving it a good texture.

[0043] It is understood that the decorative part 21 is directly fixed to the encoder rotating part 11, or the decorative part 21 is indirectly fixed to the encoder rotating part 11 through other structures; in the description of this application, "axial" refers to the extension direction of the rotation axis L around which the knob 2 and the encoder rotating part 11 rotate relative to the encoder fixing part 12, "radial" refers to the direction passing through the above-mentioned rotation axis L on the radial plane of the knob assembly 100, and the radial plane is perpendicular to the above-mentioned rotation axis L, and "axial outer end of encoder rotating part 11" refers to the end of encoder rotating part 11 that is axially away from the inside of the operation panel 1011 when the knob assembly 100 is installed on the operation panel 1011 of the cooking appliance 200.

[0044] Furthermore, the adjustment functions of the knob assembly 100 are not limited. For example, users can rotate the knob 2 to select the function of the cooking appliance 200 (such as cooking different types of food using different cooking methods, for example, if the cooking appliance 200 is a microwave-steam-grill combination appliance, the knob 2 can be rotated to select one of microwave, steaming, or grilling for cooking), rotate the knob 2 to set the values ​​of the cooking appliance 200 (such as cooking temperature, cooking time, etc.), rotate the knob 2 to turn the cooking appliance 200 on and off, or rotate the knob 2 to link with other functions of the cooking appliance 200 (such as display, voice, lights, etc.), or link with network-connected home appliances throughout the house, etc.

[0045] It is worth noting that the type of knob assembly 100 according to the embodiments of this application is not limited. It can be an encoder knob, an incremental encoder, a capacitive touch knob, or a magnetoelectric knob, etc. Among them, the encoder knob, an incremental encoder, contains an encoder. The encoder converts information such as the position and speed of mechanical motion into digital signal pulses or codes that can be recognized by the controller through photoelectric, electromagnetic, capacitive sensing methods, etc., to achieve accurate measurement and feedback of motion state. For example, when the knob is rotated, the encoder's code disk rotates accordingly. Light is alternately blocked by the code disk stripes. The photosensitive sensor receives the intermittent light signal and converts it into an electrical pulse signal. The circuit calculates the rotation angle and direction of the knob based on the number and direction of the pulses (forward / reverse rotation) and outputs a digital signal to the device processor to achieve adjustment. The surface of the capacitive touch knob is made of capacitive sensing material, and a capacitive sensor is integrated inside. When the finger rotates, the capacitance value between the finger and the knob surface changes. The sensor detects the frequency and direction of the capacitance change and converts it into an electrical signal. The chip interprets this as a rotation action to achieve adjustment. The magnetoelectric knob has a permanent magnet installed inside and a Hall sensor arranged around it. When the knob is rotated, the direction of the magnetic field of the permanent magnet changes. The Hall sensor detects the change in magnetic field, generates a corresponding electrical signal, and transmits it to the processor to achieve adjustment.

[0046] In some embodiments, such as Figures 1-8 , Figures 9(d)-9(f) As shown, the knob 2 also includes a bracket 22, which includes a pivot portion 221 and a flange portion 222. The pivot portion 221 is fitted inside and outside the encoder rotating portion 11, and the pivot portion 221 is fixedly engaged with the encoder rotating portion 11. The flange portion 222 is connected to the axial outer end of the pivot portion 221 and extends radially outward. A decorative piece 21 covers the side surface of the flange portion 222 that is away from the rotating portion, and the decorative piece 21 is fixedly connected to the flange portion 222. Here, "axial outer end of the pivot portion 221" refers to the end of the pivot portion 221 that is axially away from the interior of the control panel 1011 when the knob assembly 100 is installed on the control panel 1011 of the cooking appliance 200.

[0047] Therefore, by setting the bracket 22, the decorative part 21 is fixedly connected to the encoder rotating part 11, which facilitates the connection between the decorative part 21 and the encoder rotating part 11. At the same time, the decorative part 21 and the encoder rotating part 11 can have a large structural difference. In other words, the setting of the bracket 22 makes it easier to break the limitation that the decorative part 21 and the encoder rotating part 11 need to have a certain consistency in structure when they are directly connected. Moreover, the flange 222 is roughly annular, which makes it easier for the bracket 22 and the decorative part 21 to have a large connection area so as to achieve a reliable connection between the two. The pivot part 221 and the encoder rotating part 11 are fitted inside and outside each other, which facilitates the fixed connection between the pivot part 221 and the encoder rotating part 11.

[0048] It is understood that the fixing method between the pivot part 221 and the encoder rotating part 11 is not limited. The two can be detachably fixed or non-detachably fixed. For example, the two can be fixed by at least one of the following methods: threaded fixing, snap-fit ​​connection, adhesive fixing, interference fit fixing, etc. Similarly, the fixing method between the flange part 222 and the decorative part 21 is not limited. The two can be detachably fixed or non-detachably fixed.

[0049] As an example, both the pivot portion 221 and the encoder rotating portion 11 are generally formed into a cylindrical structure. The pivot portion 221 can be sleeved on the outside of the encoder rotating portion 11, or the encoder rotating portion 11 can be sleeved on the outside of the pivot portion 221. The flange portion 222 is located on the outer side of the encoder 1 in the axial direction so as to be connected to the decorative part 21.

[0050] In some embodiments, such as Figure 3As shown, the pivot portion 221 engages with the encoder rotating portion 11, thereby facilitating quick connection between the pivot portion 221 and the encoder rotating portion 11, improving assembly convenience, and simplifying processing and manufacturing. The specific structural forms of the encoder rotating portion 11 and the encoder fixing portion 12 are not limited; they can be the aforementioned inner and outer ring type, or other forms, which will not be elaborated here. For example, the pivot portion 221 has multiple spaced elastic buckles 221a on its peripheral wall, and the encoder rotating portion 11 has multiple spaced locking holes 11a on its peripheral wall. The elastic buckles 221a are fastened into the corresponding locking holes 11a to achieve at least circumferential limitation of the pivot portion 221 and the encoder rotating portion 11. For example, they can also achieve axial limitation of the pivot portion 221 and the encoder rotating portion 11, allowing the decorative piece 21 to drive the encoder rotating portion 11 to rotate via the bracket 22.

[0051] In some embodiments, such as Figure 3 As shown, one of the pivot portion 221 and the encoder rotating portion 11 has a limiting rib 221b and the other has a limiting groove 11b. The limiting rib 221b and the limiting groove 11b are circumferentially limitingly engaged, which helps to improve the reliability of the circumferential engagement between the two and realize synchronous rotation of the two. For example, the limiting rib 221b is formed on the pivot portion 221 and the limiting groove 11b is formed on the encoder rotating portion 11. Both the limiting rib 221b and the limiting groove 11b extend axially. There can be multiple limiting ribs 221b and limiting grooves 11b, and they are matched one-to-one. The multiple limiting ribs 221b are arranged at intervals along the circumference.

[0052] In some embodiments, such as Figure 3 As shown, the pivoting part 221 engages with the encoder rotating part 11. One of the pivoting part 221 and the encoder rotating part 11 has a limiting rib 221b, and the other has a limiting groove 11b. The limiting rib 221b and the limiting groove 11b are circumferentially limited. The encoder fixing part 12 is sleeved outside the encoder rotating part 11, and the pivoting part 221 passes through the encoder rotating part 11. In this case, the limiting rib 221b can protrude from the outer peripheral wall of the pivoting part 221, and the limiting groove 11b can be formed on the inner peripheral wall of the encoder rotating part 11. Alternatively, the encoder rotating part 11 is sleeved outside the encoder fixing part 12, and the pivoting part 221 is sleeved outside the encoder rotating part 11. In this case, the limiting rib 221b can protrude from the outer peripheral wall of the encoder rotating part 11, and the limiting groove 11b can be formed on the inner peripheral wall of the pivoting part 221. As can be seen, in the above configuration, the encoder fixing part 12 does not easily affect the snap-fit ​​between the pivot part 221 and the encoder rotating part 11, and the snap-fit ​​between the pivot part 221 and the encoder rotating part 11 does not easily affect the rotational fit between the encoder rotating part 11 and the encoder fixing part 12.

[0053] In some embodiments, such as Figure 3, Figure 8 and Figures 9(d)-9(f) As shown, the flange 222 and the decorative part 21 are bonded and fixed by the adhesive part 23, which facilitates the reliable fixing of the flange 222 and the decorative part 21.

[0054] The flange 222 has at least one groove 222a on the side of the flange facing the decorative part 21. The groove 222a can be formed by a portion of the side of the flange 222 facing the decorative part 21 recessed in a direction away from the decorative part 21. When the flange 222 is fixed to the decorative part 21, the groove 222a can hold a certain amount of adhesive liquid, which helps to increase the bonding area between the flange 222 and the decorative part 21 and improve the bonding reliability of the two. At the same time, the groove 222a also has a certain blocking effect on the adhesive liquid before curing, so that the adhesive 23 is not easy to adhere to the surface of the decorative part 21 that participates in forming the outer surface of the knob 2. That is, the adhesive 23 is not easy to adhere to the outer peripheral wall of the decorative part 21, nor is it easy to adhere to the side surface of the decorative part 21 away from the flange 222, so that the adapter is not easy to adhere to the outer surface of the knob 2 and affect the user's operating feel. Furthermore, there is no need to specially process and implement the connection structure between the flange 222 and the decorative part 21, which simplifies the structure of the flange 222 and the decorative part 21.

[0055] In addition, the traditional method of embedding knobs with screens and lights results in noticeable gaps, while crystal knobs present a seamless effect directly on the back. The above-mentioned design in this application helps to improve the noticeable gaps and enhance the appearance.

[0056] Of course, in other embodiments of this application, the connection between the flange 222 and the decorative part 21 can also be a threaded connection, a snap-fit ​​connection, etc.

[0057] In some embodiments, such as Figure 3 As shown, there are multiple grooves 222a, each extending into a ring shape, and the multiple grooves 222a are arranged radially at intervals. This facilitates increasing the bonding area between the flange 222 and the decorative part 21 while also ensuring that the grooves 222a effectively block the adhesive. Of course, there can also be only one groove 222a, in which case the groove 222a can also extend into a ring shape.

[0058] It should be noted that "ring" is interpreted broadly, meaning it is not limited to "circular rings". For example, it can also refer to "polygonal rings", etc., and can include closed rings and open rings.

[0059] In some embodiments, such as Figure 3 , Figure 8 and Figures 9(d)-9(f)As shown, a decorative layer 24 is provided between the decorative part 21 and the flange 222. The decorative layer 24 has decorative information, which can be displayed through the decorative part 21. At the same time, the decorative layer 24 can cover the bracket 22 and the encoder 1 to a certain extent, so that the internal structure of the knob assembly 100 is not exposed too much through the decorative part 21. And / or, the bracket 22 is a plastic or metal part, which makes it easy for the bracket 22 to have good structural strength and good processing feasibility, and easy to process into the required shape. The bracket 22 can also serve as the base of the decorative part 21, and can also be used to increase the decoration. Of course, the bracket 22 can also be an opaque material part of other materials.

[0060] It is understood that if a decorative layer 24 is provided between the decorative element 21 and the flange 222, the decorative layer 24 can be provided independently of the decorative element 21 and the flange 222, or the decorative layer 24 can be attached to the side surface of the decorative element 21 facing the flange 222, or the decorative layer 24 can be attached to the side surface of the flange 222 facing the decorative element 21.

[0061] As an example, a decorative layer 24 is provided between the decorative part 21 and the flange 222, and the flange 222 and the decorative part 21 are bonded and fixed by the adhesive 23. The decorative layer 24 can be located between the adhesive 23 and the decorative part 21 to ensure that the decorative information (such as patterns and / or text) of the decorative layer 24 can be seen through the decorative part 21 and is not easily blocked by the adhesive 23, and there is no limitation on the light transmittance of the adhesive 23.

[0062] As an example, the decorative layer 24 can be provided between the decorative part 21 and the flange 222 by screen printing.

[0063] In some embodiments, such as Figures 1-9(f) As shown, the decorative element 21 is constructed to satisfy at least one of the following structures A1 to A5: Structure A1, as shown in the figure. Figures 1-3 As shown in Figures 9(c) and 9(f), the outer peripheral wall of the decorative part 21 is formed as a smooth curved surface (e.g., cylindrical, conical, elliptical, pebble-like surface, etc.), which is convenient for processing and has no sharp edges, thus improving the handling feel. Alternatively, the outer peripheral wall of the decorative part 21 has anti-slip ridges 21a, which increases the friction between the decorative part 21 and the user when the user holds and rotates the outer peripheral wall of the decorative part 21, thus improving the ease of operation; Structure A2, as Figures 1-9(f)As shown, the outer periphery of the decorative part 21 has chamfers 21b at both axial ends. When the user wants to operate the knob 2, they usually touch the outer periphery of the decorative part 21 first. By setting this as a smooth chamfer 21b, it is beneficial to protect the user during operation; Structure A3, the light transmittance of the decorative part 21 is greater than or equal to 80%; Structure A4, the decorative part 21 is made of crystal, acrylic, polycarbonate plastic, saline plastic, or glass, which facilitates exquisite processing details, durable materials, and will not stain or yellow after long-term use, maintaining a transparent and pure texture. It is not easy to scratch, easy to clean, and is conducive to more integrated with the screen and lights. The overall transparency and seamlessness can differentiate it from the current industry knobs, improve the user experience, and enhance the product's market competitiveness; for cooking utensils, it adds a unique brand image at a lower cost, differentiating it from competitors; Structure A5, the decorative part 21 is bonded and fixed to the encoder rotating part 11, and the decorative part 21 is directly bonded and fixed to the encoder rotating part 11 (such as... Figures 9(a)-9(c) (as shown), or indirectly fixed by other components (such as the bracket 22 described above). Figures 9(d)-9(f) (As shown).

[0064] In related technologies, knobs are mainly concentrated on solid-color plastic injection molding, spraying and metal oxidation. The texture is opaque plastic or metal material. Transparent plastic knobs with similar appearance have rough details, poor transparency, are prone to air bubbles, are easily damaged by impacts and scratches, and will develop problems such as staining, yellowing and ice cracking after long-term use. Structure A4 can overcome the above problems better.

[0065] As an example, decorative piece 21 is made of crystal. Compared with common metal knobs, crystal knobs are more user-friendly and have a more natural and approachable texture, giving the product a more dynamic and warm characteristic. Compared with common plastic knobs, crystal knobs have a more valuable feel. Plastic knobs give people a cheap plastic feel and do not significantly improve the product's appearance value. Crystal has always been a natural and luxurious material for consumers, which enhances the product's appearance value.

[0066] As an example, in structure A1, when the outer peripheral wall of the decorative element 21 has anti-slip ridges 21a, there can be multiple anti-slip ridges 21a. Multiple anti-slip ridges 21a can be spaced apart along the circumference of the decorative element 21. Each anti-slip ridge 21a extends along the axial direction. The outer peripheral wall of the decorative element 21 can include multiple cut surfaces. The intersection line between two adjacent cut surfaces defines the anti-slip ridge 21a. The cut surfaces can be planar or curved. As an example, the outer peripheral wall of the decorative element 21 can be constructed as a diamond-cut surface.

[0067] As an example, in structure A2, chamfer 21b can be a chamfer or a rounded corner, and the angle of the chamfer can be 45° or 30°, etc.

[0068] As an example, when the decorative element 21 is constructed to satisfy structure A1 and structure A2, if the outer peripheral wall of the decorative element 21 is formed as a smooth curved surface, then the portion of the outer peripheral wall of the decorative element 21 other than the chamfer 21b is formed as a smooth curved surface, or the outer peripheral wall of the decorative element 21 including the chamfer 21b is formed as a smooth curved surface; if the outer peripheral wall of the decorative element 21 has an anti-slip edge 21a, then the portion of the outer peripheral wall of the decorative element 21 other than the chamfer 21b has an anti-slip edge 21a, or the outer peripheral wall of the decorative element 21 including the chamfer 21b has an anti-slip edge 21a.

[0069] As an example, in structure A3, the light transmittance of decorative element 21 is 80%, 82%, 85%, 88%, 90%, or 95%, etc.

[0070] In some embodiments, the knob assembly 100 further includes: a display unit disposed within the encoder 1 and axially opposite to the decorative element 21, wherein the information displayed by the display unit can be displayed through the decorative element 21 for viewing by the user; and / or a light-emitting unit disposed within the encoder 1 and axially opposite to the decorative element 21, wherein the light signal emitted by the light-emitting unit can be displayed through the decorative element 21 for viewing by the user.

[0071] As can be seen, the display unit and / or the light-emitting unit can be combined with the knob 2. Users can view the information of the display unit and / or the light-emitting unit through the decorative piece 21, which helps to improve the interactivity of the cooking appliance 200. The display unit has the function of displaying information, and the light-emitting unit has the function of emitting light. The structure and display principle of the display unit and the structure and light-emitting principle of the light-emitting unit are well known to those skilled in the art and will not be described in detail here.

[0072] For example, the encoder rotating part 11 and the encoder fixing part 12 are fitted together with each other, and the display unit and / or light-emitting unit is located inside the inner side of one of the encoder rotating part 11 and the encoder fixing part 12; for example, the encoder fixing part 12 is fitted outside the encoder rotating part 11 and the display unit and / or light-emitting unit is located inside the encoder rotating part 11, while if the encoder rotating part 11 is fitted outside the encoder fixing part 12, the display unit and / or light-emitting unit is located inside the encoder fixing part 12.

[0073] As an example, the knob 2 also includes a bracket 22, which includes a pivot portion 221 and a flange portion 222. The pivot portion 221 is fitted inside and outside the encoder rotating portion 11, and the pivot portion 221 is fixedly engaged with the encoder rotating portion 11.

The decorative piece 21 covers the side surface of the flange portion 222 that is away from the rotating portion, and the decorative piece 21 is fixedly connected to the flange portion 222. At this time, the encoder fixing part 12 is sleeved outside the encoder rotating part 11, the pivot part 221 is inserted inside the encoder rotating part 11, and the display unit and / or light-emitting unit is disposed inside the pivot part 221. The display unit and / or light-emitting unit can be fixed to the pivot part 221 so that the display unit and / or light-emitting unit rotates with the knob 2. Of course, the display unit and / or light-emitting unit can also be fixed to the encoder fixing part 12 so that the display unit and / or light-emitting unit is fixed relative to the encoder fixing part 12 and does not rotate with the knob 2. However, if the encoder rotating part 11 is sleeved outside the encoder fixing part 12, the pivot part 221 is sleeved outside the encoder rotating part 11, and the display unit and / or light-emitting unit is disposed inside the encoder fixing part 12, the display unit and / or light-emitting unit can be fixed to the encoder fixing part 12 and does not rotate with the knob 2. Of course, the display unit and / or light-emitting unit can also be fixed to the pivot part 221.

[0074] It can be understood that the entire decorative part 21 is transparent; or, a part of the decorative part 21 is formed as a transparent part. For example, the decorative part 21 includes a first decorative part and a second decorative part.
