Description

Technical Field

[0001] This application belongs to the field of household appliance technology, specifically relating to a cooking appliance. Background Technology

[0002] For cooking appliances such as ovens and microwave ovens with oven functions, the heating element is a critical component. During installation, the heating element needs to be securely and reliably fixed in the appliance to prevent damage from drops during transportation, while also needing to be easy and quick to install to meet production requirements. Related solutions propose a heating element with flat ends, but how to install such a flat-end heating element remains a pressing problem to be solved. Utility Model Content

[0003] This application aims to solve the technical problem of how to install a heating element with flat ends in the cooking equipment in the relevant solution.

[0004] To address the aforementioned technical problems, embodiments of this application provide a cooking utensil.

[0005] An embodiment of this application provides a cooking appliance, including: a cavity with a mounting hole; a heating element, a portion of which is installed in the cavity, one end of which extends out of the cavity from the mounting hole, and a flat portion is provided on the end of the heating element extending out of the cavity; and at least one fixing bracket disposed outside the cavity and located at one end of the heating element, the fixing bracket including a support plate and a pressing structure, the flat portion being pressed onto the support plate by the pressing structure.

[0006] The cooking appliance according to the embodiments of this application includes a cavity, a heating element, and at least one fixing bracket. The cavity has a mounting hole, and a portion of the heating element is installed inside the cavity, with one end extending out of the cavity through the mounting hole and having a flattened portion. Simultaneously, a fixing bracket is provided outside the cavity at one end of the heating element. The fixing bracket includes a support plate and a pressing structure, which presses the flattened portion of the heating element onto the support plate. This structure effectively enhances the stability of the extended end of the heating element, preventing it from shaking or shifting during use, ensuring that the heating element can continuously and stably provide heat to the cavity, thereby improving the overall reliability and consistency of the cooking effect of the cooking appliance, and increasing the product's performance and service life.

[0007] Furthermore, this structure, which uses a press-fit mechanism to fix the protruding end of the heating element, is particularly suitable for fixing heating elements with flat ends, effectively solving the problem of how to install and fix heating elements with flat ends.

[0008] The press-fit structure can press the flat part by elastic rebound, or it can be fixed to the cavity by screws, etc., and then press the flat part.

[0009] In any of the above embodiments, optionally, the press-fitting structure includes one or more elastic sheets, one end of the elastic sheet away from the cavity is connected to the support plate, and the other end of the elastic sheet near the cavity is spaced apart from the support plate. At least a portion of the flat portion is inserted into the gap formed between the one or more elastic sheets and the support plate, and the elastic sheets are in an elastically deformed state so that at least a portion of the flat portion is elastically pressed onto the support plate by the one or more elastic sheets.

[0010] In this embodiment, the press-fit structure includes one or more elastic sheets. One end of the elastic sheet is connected to a support plate, and the other end is spaced apart from the support plate, allowing at least a portion of the flat portion of the heating element to be inserted into the space. At this time, the elastic sheet is in an elastically deformed state, enabling the flat portion to be securely fixed to the support plate via elastic press-fit. This structure utilizes the elasticity of the elastic sheet to compress the flat portion. The elastic press-fit method possesses a certain degree of self-adaptability, allowing for good adaptation and fixation of flat portions of different sizes and specifications through the elastic deformation of the elastic sheet. This greatly improves the compatibility of the cooking appliance with different heating elements, broadens the product's application range, and extends its service life while improving product performance, providing users with a better and more convenient user experience. Furthermore, the elastic sheet provides continuous and stable clamping force, further enhancing the fixing stability of the protruding end of the heating element. Simultaneously, this press-fit structure does not require additional screws, and its structure is relatively simple, thus reducing the overall product cost.

[0011] To ensure the connection stability between the press-fit structure and the support plate, the press-fit structure and the support plate can be designed as an integral structure. Furthermore, the press-fit structure and the support plate are integrally molded.

[0012] In any of the above embodiments, optionally, the press-fit structure includes two elastic sheets arranged side by side and spaced apart, one side of the flat portion is elastically press-fitted between one of the elastic sheets and the support plate, and the other side of the flat portion is elastically press-fitted between the other elastic sheet and the support plate.

[0013] In this embodiment, the press-fit structure includes two elastic sheets arranged side-by-side and spaced apart. Each side of the flat portion of the heating element is positioned within the gap formed by an elastic sheet and a support plate. Because the elastic sheets undergo elastic deformation during installation, a continuous and stable elastic clamping force is applied to the flat portion, achieving a secure fixation of the heating element. This double-elastic-sheet design improves the reliability of the heating element's fixation in several ways. First, the double-sided elastic press-fit greatly enhances the stability of the fixation, better coping with vibrations generated during cooking and potential displacement of the heating element, ensuring that the heating element is always in the optimal working position, stably and efficiently supplying heat to the cavity, effectively guaranteeing the overall reliability of the cooking appliance and improving the consistency of cooking results.

[0014] In any of the above embodiments, optionally, the fixed bracket further includes a support rod, one end of the support plate near the cavity is mounted on the support rod, and the other end of the support plate away from the cavity is suspended; the end of the elastic sheet away from the cavity is connected to the suspended end of the support plate.

[0015] In this embodiment, the fixing bracket includes a support rod. One end of the support plate near the cavity is securely mounted on the support rod, while the other end away from the cavity is suspended. The end of the elastic sheet away from the cavity is also connected to the suspended end of the support plate. This structure, with the support plate suspended, allows the elastic sheet more flexible deformation space when elastically pressing the flat portion of the heating element. It can generate more suitable elastic deformation according to the actual situation of the flat portion of the heating element, thereby applying a more stable and precise elastic clamping force, greatly enhancing the stability of the heating element's fixation. Furthermore, because the suspended support plate gives the elastic sheet greater deformation freedom, it can achieve good fixation for flat heating elements of different sizes and shapes through more sufficient adaptive deformation, significantly improving the compatibility of the cooking appliance with various heating elements and broadening the product's application range.

[0016] In any of the above embodiments, optionally, mounting holes are provided on the opposite sides of the cavity, and two fixing brackets are provided on the outside of the opposite sides of the cavity; the two ends of the heating tube extend from the opposite sides of the cavity through the mounting holes and are supported and mounted on the two fixing brackets.

[0017] In this embodiment, mounting holes are provided on both opposite sides of the cavity, and two fixing brackets are correspondingly provided, each mounted on the outside of the cavity. The two ends of the heating element extend from the opposite sides of the cavity through the mounting holes and are then supported and mounted on the two fixing brackets. This structure allows both ends of the heating element to be press-fitted and fixed by the fixing brackets, ensuring the consistency of the fixing structure at both ends of the heating element. Of course, in other solutions, different structural designs can be used for the fixing structure at both ends of the heating element.

[0018] In any of the above embodiments, optionally, the number of heating tubes is one or more. When there are multiple heating tubes, the multiple heating tubes are arranged side by side, and the same end of the multiple heating tubes is supported and installed on the same fixed bracket. The fixed bracket is provided with multiple support plates and multiple pressing structures, and the multiple flat parts of the multiple heating tubes are pressed one-to-one between the multiple support plates and the multiple pressing structures.

[0019] In this embodiment, the number of heating elements can be set to one or more as needed. When there are multiple heating elements, they are arranged side by side, and the same end of each heating element is supported and installed on the same fixed bracket. The fixed bracket is equipped with a support plate and a pressing structure for each heating element, and the flat portion of each heating element can be pressed into the corresponding support plate and pressing structure. This structure, with multiple heating elements, greatly improves the heating power and efficiency of the cooking appliance, enabling rapid increase in the internal temperature of the cavity to meet the user's demand for fast cooking. Simultaneously, because multiple heating elements use a consistent fixing method, each heating element achieves a stable and reliable fixing effect. During operation, even if complex vibrations occur due to the simultaneous operation of multiple heating elements, displacement can be effectively resisted, maintaining optimal working condition and continuously and stably supplying heat to the cavity, effectively ensuring the overall reliability of the cooking appliance. Furthermore, the side-by-side arrangement of multiple heating elements allows heat to be distributed more evenly within the cavity space, and the unified and stable fixing method ensures more balanced heat transfer from each heating element. In addition, this design with multiple heating elements and their fixing method is highly versatile and expandable, making it easy to flexibly adjust the number of heating elements according to the size and functional requirements of different cooking utensils, and facilitating its application in products of different models and specifications.

[0020] In any of the above embodiments, optionally, the fixing bracket includes a limiting structure, which is disposed on both sides of the flat portion for limiting the two sides of the flat portion.

[0021] In this embodiment, the fixing bracket also includes a limiting structure. The limiting structure is located on both sides of the flat portion, enabling more precise positioning of the heating element. This structure, where the limiting structure and the pressing structure work together, greatly enhances the fixing effect on the heating element. During the operation of the cooking appliance, multiple heating elements working simultaneously can easily generate complex vibrations. The limiting structure effectively prevents the flat portion of the heating element from shifting horizontally, and combined with the vertical clamping force of the pressing structure, ensures the heating element is stable from all directions.

[0022] In any of the above embodiments, optionally, a support portion is provided on the outer side of the cavity, and a fixed bracket is supported and installed on the support portion.

[0023] In this embodiment, a support portion is provided on the outer side of the cavity, and the fixed bracket is supported and installed on the support portion. The support portion provides an installation platform for the fixed bracket, improving the ease of installation and ensuring the stability of the fixed bracket after installation.

[0024] In any of the above embodiments, optionally, one of a plug-in protrusion and a plug-in hole is provided on the outer side of the cavity, and the other of a plug-in protrusion and a plug-in hole is provided on the fixed bracket. When the fixed bracket is installed on the cavity, the plug-in protrusion is plugged into the plug-in hole.

[0025] In this embodiment, the connection stability between the fixing bracket and the cavity can be further improved by the cooperation of the insertion protrusion and the insertion hole. At the same time, the positioning cooperation of the insertion protrusion and the insertion hole can also limit the installation position of the fixing bracket and ensure the installation accuracy of the fixing bracket.

[0026] In any of the above embodiments, the heating element may optionally be a graphene heating element.

[0027] In this embodiment, graphene, as a novel heating element, possesses excellent electrical and thermal conductivity, resulting in higher heating efficiency, faster heating speed, and stronger radiation intensity compared to traditional metal heating elements. Applying graphene to cooking appliances allows for rapid food processing through thermal radiation, reducing cooking time and improving the taste of the cooked food.

[0028] In any of the above embodiments, the fixing bracket and the cavity may optionally be an integral structure or a detachable structure.

[0029] In this embodiment, when the fixing bracket and the cavity adopt an integrated structure, they become an inseparable whole, which can significantly improve the stability of the fixing bracket, thereby improving the installation stability of the heating element. Of course, the fixing bracket and the cavity can also be set as different parts and then assembled together. In this case, the original cavity structure does not need to be changed, making the cavity have a certain degree of versatility.

[0030] In any of the above embodiments, optionally, when the fixing bracket and the cavity are detachable structures, the fixing bracket is installed on the cavity through a threaded connector, the fixing bracket is provided with a first screw hole for the threaded connector to pass through, and the cavity is provided with a second screw hole for the threaded connector to pass through.

[0031] In this embodiment, the fixing bracket and the cavity are detachable. The fixing bracket can be installed on the cavity via a threaded connector. To facilitate the installation of the threaded connector, the fixing bracket has a first screw hole for the threaded connector to pass through, and the cavity has a second screw hole for the threaded connector to pass through. This structure simplifies the installation of the cavity and the fixing bracket, thereby simplifying the overall product structure and reducing product cost.

[0032] In any of the above embodiments, optionally, the cavity includes a top plate, a portion of which protrudes upward along the height direction of the cavity to form a protrusion, and mounting holes are provided on opposite sides of the protrusion, and the two ends of the heating tube pass through the mounting holes, pass through the protrusion, and extend out of the cavity.

[0033] In this embodiment, a portion of the top plate protrudes upwards along the height of the cavity to form a raised section, and mounting holes are provided on opposite sides of the raised section. The two ends of the heating element pass through these mounting holes, pass through the raised section, and extend out of the cavity. This structure allows for the design of space on the top plate of the cavity for mounting the heating element. Compared to providing mounting holes on the side of the cavity, this design avoids occupying the horizontal space inside the cavity, allowing for a more rational planning of the cooking area, improving space utilization, and providing users with a more spacious and practical cooking space. It is especially suitable for cooking appliances with high requirements for internal space layout.

[0034] Furthermore, a tight-fitting sealing structure can be used between the mounting hole and the heating element to effectively prevent heat leakage from the mounting hole, improve the sealing of the cavity, further enhance the energy utilization efficiency of the cooking appliance, reduce energy consumption, and bring users a more energy-saving and environmentally friendly cooking experience.

[0035] In any of the above embodiments, the cooking appliance may optionally include a heat insulation cover, which is installed on the outer wall surface of the cavity corresponding to the location of the heating element.

[0036] In this embodiment, the heat insulation cover can protect the heating element and enhance the heat insulation effect of the cavity, reduce the heat loss of the heating element, and improve the heat utilization rate of the heating element.

Detailed Implementation

[0049] The embodiments of this application will now be described in detail. Examples of these embodiments are illustrated 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 application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0050] The cooking appliance according to embodiments of this application will now be described with reference to the accompanying drawings.

[0051] like Figures 1 to 8 As shown, an embodiment of this application provides a cooking appliance, including a cavity 1, a heating element 2, and at least one fixing bracket 3. The cavity 1 has a mounting hole 12. A portion of the heating element 2 is installed inside the cavity 1, with one end of the heating element 2 extending out of the cavity 1 from the mounting hole 12. A flat portion 22 is provided on the end of the heating element 2 extending out of the cavity 1. At least one fixing bracket 3 is disposed outside the cavity 1 and located at one end of the heating element 2. The fixing bracket 3 includes a support plate 32 and a pressing structure 34, with the flat portion 22 pressed onto the support plate 32 by the pressing structure 34. The cavity 1, the heating element 2, and at least one fixing bracket 3 are assembled to form a heating element fixing structure.

[0052] The cooking appliance according to the embodiments of this application includes a cavity 1, a heating element 2, and at least one fixing bracket 3. The cavity 1 has a mounting hole 12. A portion of the heating element 2 is installed inside the cavity 1, and one end extends out of the cavity 1 through the mounting hole 12 and has a flat portion. Simultaneously, a fixing bracket 3 is provided outside the cavity 1 at one end of the heating element 2. The fixing bracket 3 includes a support plate 32 and a pressing structure 34, which presses the flat portion of the heating element 2 onto the support plate 32. This structure effectively enhances the stability of the extended end of the heating element 2, preventing it from shaking or shifting during use, ensuring that the heating element 2 can continuously and stably provide heat to the cavity 1, thereby improving the overall reliability and consistency of the cooking effect of the cooking appliance, and increasing the product's performance and service life.

[0053] Furthermore, since this structure uses a press-fit structure 34 to fix the protruding end of the heating tube 2, it is particularly suitable for fixing the heating tube 2 of the flat part 22, effectively solving the problem of how to install and fix the heating tube 2 with flat ends.

[0054] The press-fit structure 34 can press the flat part 22 by elastic rebound, or it can be fixed to the cavity 1 by screws, etc., and then press the flat part 22.

[0055] In any of the above embodiments, optionally, as Figure 1 , Figure 4 As shown, the press-fit structure 34 includes one or more elastic sheets 342. The end of the elastic sheet 342 away from the cavity 1 is connected to the support plate 32, and the end of the elastic sheet 342 near the cavity 1 is spaced apart from the support plate 32. At least a portion of the flat portion 22 is inserted into the gap formed between the one or more elastic sheets 342 and the support plate 32. The elastic sheet 342 is in an elastically deformed state so that at least a portion of the flat portion 22 is elastically pressed onto the support plate 32 by the one or more elastic sheets 342.

[0056] In this embodiment, the press-fit structure 34 includes one or more elastic sheets 342. One end of the elastic sheet 342 is connected to the support plate 32, and the other end is spaced apart from the support plate 32, allowing at least a portion of the flat portion of the heating element 2 to be inserted into the space. At this time, the elastic sheet 342 is in an elastically deformed state, and can securely fix the flat portion to the support plate 32 by elastic press-fit. This structure utilizes the elasticity of the elastic sheet 342 to press the flat portion 22 tightly. The elastic press-fit method has a certain degree of self-adaptability; for flat portions of different sizes and specifications, the elastic deformation of the elastic sheet 342 can achieve good adaptation and fixation, greatly improving the compatibility of the cooking appliance with different heating elements 2, broadening the product's application range, improving product performance while extending its service life, and providing users with a better and more convenient user experience. Furthermore, the elastic sheet 342 can provide continuous and stable pressing force, further enhancing the fixing stability of the protruding end of the heating element 2. At the same time, this press-fit structure 34 does not require additional screws, and its structure is relatively simple, thus reducing the overall product cost.

[0057] To ensure the connection stability between the press-fit structure 34 and the support plate 32, the press-fit structure 34 and the support plate 32 can be configured as an integral structure. Furthermore, the press-fit structure 34 and the support plate 32 are integrally formed.

[0058] In any of the above embodiments, optionally, as Figure 1 , Figure 2 and Figure 4 As shown, the press-fit structure 34 includes two elastic sheets 342. The two elastic sheets 342 are arranged side by side and spaced apart. One side of the flat portion 22 is elastically press-fitted between one of the elastic sheets 342 and the support plate 32, and the other side of the flat portion 22 is elastically press-fitted between the other elastic sheet 342 and the support plate 32.

[0059] In this embodiment, the press-fit structure 34 includes two parallel and spaced elastic plates 342. Each side of the flat portion of the heating element 2 is respectively positioned within the gap formed by an elastic plate 342 and a support plate 32. Because the elastic plates 342 undergo elastic deformation during installation, a continuous and stable elastic pressing force is applied to the flat portion, achieving a secure fixation of the heating element 2. This design with double elastic plates 342 improves the reliability of the heating element 2's fixation in several ways. First, the double-sided elastic press-fit greatly enhances the stability of the fixation, better coping with vibrations generated during cooking and potential displacement of the heating element 2, ensuring that the heating element 2 is always in the optimal working position, stably and efficiently supplying heat to the cavity 1, effectively guaranteeing the overall reliability of the cooking appliance and improving the consistency of cooking results.

[0060] In any of the above embodiments, optionally, as Figure 1 , Figure 4 and Figure 5 As shown, the fixed bracket 3 also includes a bracket rod 30, and the end of the support plate 32 near the cavity 1 is mounted on the bracket rod 30, while the end of the support plate 32 away from the cavity 1 is suspended; the end of the elastic sheet 342 away from the cavity 1 is connected to the suspended end of the support plate 32.

[0061] In this embodiment, the fixing bracket 3 includes a bracket rod 30. One end of the support plate 32 near the cavity 1 is securely mounted on the bracket rod 30, while the other end away from the cavity 1 is suspended. The end of the elastic sheet 342 away from the cavity 1 is also connected to the suspended end of the support plate 32. This structure allows the suspended support plate 32 to have more flexible deformation space when the elastic sheet 342 elastically presses against the flat portion of the heating element 2. It can generate more suitable elastic deformation according to the actual situation of the flat portion of the heating element 2, thereby applying a more stable and precise elastic clamping force, greatly enhancing the stability of the heating element 2. On the other hand, because the suspended support plate 32 gives the elastic sheet 342 greater deformation freedom, the elastic sheet 342 can achieve good fixation for flat heating elements 2 of different sizes and shapes through more sufficient adaptive deformation, significantly improving the compatibility of the cooking appliance with various heating elements 2 and broadening the product's application range.

[0062] In any of the above embodiments, optionally, as Figure 6 and Figure 7 As shown, mounting holes 12 are provided on the opposite sides of the cavity 1. There are two fixing brackets 3, which are respectively set on the outside of the opposite sides of the cavity 1; the two ends of the heating tube 2 extend from the opposite sides of the cavity 1 through the mounting holes 12 and are supported and installed on the two fixing brackets 3.

[0063] In this embodiment, mounting holes 12 are provided on both opposite sides of the cavity 1, and two fixing brackets 3 are correspondingly provided, which are respectively installed on the outside of the two sides of the cavity 1. The two ends of the heating tube 2 extend from the opposite sides of the cavity 1 through the mounting holes 12, and are then supported and installed on the two fixing brackets 3. This structure allows both ends of the heating tube 2 to be press-fitted and fixed by the fixing brackets 3, ensuring the consistency of the fixing structure at both ends of the heating tube 2. Of course, in other solutions, different structural designs can be used for the fixing structure at both ends of the heating tube 2.

[0064] In any of the above embodiments, optionally, as Figure 6 and Figure 8As shown, there are one or more heating tubes 2. When there are multiple heating tubes 2, the multiple heating tubes 2 are arranged side by side, and the same end of the multiple heating tubes 2 is supported and installed on the same fixed bracket 3. The fixed bracket 3 is provided with multiple support plates 32 and multiple pressing structures 34. The multiple flat parts 22 of the multiple heating tubes 2 are pressed one by one between the multiple support plates 32 and the multiple pressing structures 34.

[0065] In this embodiment, the number of heating elements 2 can be set to one or more as needed. When there are multiple heating elements 2, they are arranged side by side, and the same end of multiple heating elements 2 is supported and installed on the same fixed bracket 3. The fixed bracket 3 is provided with a support plate 32 and a pressing structure 34 for each heating element 2, and the flat part of each heating element 2 can be pressed between the corresponding support plate 32 and pressing structure 34. With this structure, the configuration of multiple heating elements 2 greatly improves the heating power and efficiency of the cooking appliance, and can quickly increase the internal temperature of the cavity 1 to meet the user's demand for fast cooking. At the same time, since multiple heating elements 2 adopt the same fixing method, it ensures that each heating element 2 can obtain a stable and reliable fixing effect. When the cooking appliance is running, even if complex vibrations are generated due to the simultaneous operation of multiple heating elements 2, it can effectively resist displacement, always maintain the best working state, and continuously and stably supply heat to the cavity 1, which strongly guarantees the overall reliability of the cooking appliance. Furthermore, the multiple heating elements 2 arranged side by side allow for a more even distribution of heat within the cavity 1. Combined with a uniform and stable fixing method, this ensures more balanced heat transfer across all heating elements 2. In addition, this design of multiple heating elements 2 and their fixing method offers high versatility and expandability, allowing for flexible adjustment of the number of heating elements 2 according to the size and functional requirements of different cooking appliances, facilitating widespread application in products of various models and specifications.

[0066] In any of the above embodiments, optionally, as Figure 1 and Figure 4 As shown, the fixed bracket 3 includes a limiting structure 36, which is disposed on both sides of the flat portion 22 and is used to limit the two sides of the flat portion 22.

[0067] In this embodiment, the fixing bracket 3 also includes a limiting structure 36. The limiting structure 36 is located on both sides of the flat portion, enabling more precise positioning of the heating element 2. This structure, where the limiting structure 36 and the pressing structure 34 work simultaneously, greatly enhances the fixing effect on the heating element 2. During the operation of the cooking appliance, the simultaneous operation of multiple heating elements 2 can easily generate complex vibrations. The limiting structure 36 effectively prevents the flat portion of the heating element 2 from shifting horizontally, and combined with the vertical pressing force of the pressing structure 34, ensures the heating element 2 is stable in all directions.

[0068] In any of the above embodiments, optionally, as Figure 1 , Figure 4 , Figure 6 and Figure 7 As shown, a support part 14 is provided on the outer side of the cavity 1, and the fixed bracket 3 is supported and installed on the support part 14.

[0069] In this embodiment, a support portion 14 is provided on the outer side of the cavity 1, and the fixing bracket 3 is supported and installed on the support portion 14. The support portion 14 provides an installation platform for the fixing bracket 3, which improves the installation convenience of the fixing bracket 3 and ensures the stability of the fixing bracket 3 after installation.

[0070] In any of the above embodiments, optionally, as Figure 1 , Figure 4 , Figure 6 and Figure 7 As shown, the outer side of the cavity 1 is provided with one of the insertion protrusion 16 and the insertion hole 39, and the fixed bracket 3 is provided with the other of the insertion protrusion 16 and the insertion hole 39. When the fixed bracket 3 is installed on the cavity 1, the insertion protrusion 16 is inserted into the insertion hole 39.

[0071] In this embodiment, the connection stability between the fixing bracket 3 and the cavity 1 can be further improved by the cooperation of the insertion protrusion 16 and the insertion hole 39. At the same time, the positioning cooperation of the insertion protrusion 16 and the insertion hole 39 can also limit the installation position of the fixing bracket 3 and ensure the installation accuracy of the fixing bracket 3.

[0072] In any of the above embodiments, the heating element 2 may optionally be a graphene heating element.

[0073] In this embodiment, graphene, as a novel heating element, possesses excellent electrical and thermal conductivity, resulting in higher heating efficiency, faster heating speed, and stronger radiation intensity compared to traditional metal heating elements. Applying graphene to cooking appliances allows for rapid food processing through thermal radiation, reducing cooking time and improving the taste of the cooked food.

[0074] In any of the above embodiments, optionally, the fixing bracket 3 and the cavity 1 are an integral structure (not shown in the figure) or as... Figure 1 , Figure 4 , Figure 6 and Figure 7 As shown, the fixed bracket 3 and the cavity 1 are detachable structures.

[0075] In this embodiment, when the fixing bracket 3 and the cavity 1 adopt an integrated structure, they become an inseparable whole, which can significantly improve the stability of the fixing bracket 3, thereby improving the installation stability of the heating tube 2. Of course, the fixing bracket 3 and the cavity 1 can also be set as different parts and then assembled together. In this case, the original structure of the cavity 1 does not need to be changed, making the cavity 1 have a certain degree of versatility.

[0076] In any of the above embodiments, optionally, as Figure 1 , Figure 4 , Figure 6 and Figure 7 As shown, the fixed bracket 3 and the cavity 1 are detachable structures. The fixed bracket 3 is installed on the cavity 1 through the threaded connector 5. The fixed bracket 3 is provided with a first screw hole 38 for the threaded connector 5 to pass through, and the cavity 1 is provided with a second screw hole 142 for the threaded connector 5 to pass through.

[0077] In this embodiment, the fixing bracket 3 and the cavity 1 are detachable. The fixing bracket 3 can be installed on the cavity 1 via a threaded connector 5. To facilitate the installation of the threaded connector 5, the fixing bracket 3 has a first screw hole 38 for the threaded connector 5 to pass through, and the cavity 1 has a second screw hole 142 for the threaded connector 5 to pass through. This structure simplifies the installation of the cavity 1 and the fixing bracket 3, thereby simplifying the overall product structure and reducing product cost.

[0078] In any of the above embodiments, optionally, as Figures 1 to 8 As shown, the cavity 1 includes a top plate 18. A portion of the top plate 18 protrudes upward along the height direction of the cavity 1 to form a protrusion 182. Mounting holes 12 are provided on the two opposite sides of the protrusion 182. The two ends of the heating tube 2 pass through the mounting holes 12, pass through the protrusion 182, and extend out of the cavity 1.

[0079] In this embodiment, a portion of the top plate 18 protrudes upward along the height direction of the cavity 1 to form a protrusion 182, and mounting holes 12 are provided on opposite sides of the protrusion 182. Both ends of the heating element 2 pass through these mounting holes 12, pass through the protrusion 182, and extend out of the cavity 1. This structure allows for the design of space on the top plate 18 of the cavity 1 for mounting the heating element 2. Compared to providing mounting holes 12 on the side of the cavity 1, this design avoids occupying the horizontal space inside the cavity 1, allowing for a more rational planning of the cooking area within the cavity 1, improving space utilization, and providing users with a more spacious and practical cooking space. It is especially suitable for cooking appliances with high requirements for internal space layout.

[0080] Furthermore, a tight-fitting sealing structure can be adopted between the mounting hole 12 and the heating element 2 to effectively prevent heat leakage from the mounting hole 12, improve the sealing performance of the cavity 1, further enhance the energy utilization efficiency of the cooking appliance, reduce energy consumption, and bring users a more energy-saving and environmentally friendly cooking experience.

[0081] In any of the above embodiments, optionally, as Figures 1 to 8As shown, the cooking appliance also includes a heat insulation cover 4, which is installed on the outer wall of the cavity 1 at the location corresponding to the heating tube 2.

[0082] In this embodiment, the heat insulation cover 4 can protect the heating tube 2, enhance the heat insulation effect of the cavity 1, reduce the heat loss of the heating tube 2, and improve the heat utilization rate of the heating tube 2.

[0083] Optionally, the cooking appliance also includes an outer shell. The cavity 1 is installed inside the outer shell as an inner pot. The outer shell protects the inner pot and also enhances its heat retention. Other components can also be installed between the outer shell and the inner pot. The outer shell serves as an exterior component, preventing exposed parts and ensuring the aesthetic appeal of the cooking appliance.

[0084] Optionally, the cooking appliance also includes a door, with a cooking cavity provided inside the cavity 1, and the door is installed on the outer shell for opening and closing the cooking cavity.

[0085] The following describes a specific heating element fixing structure.

[0086] As a novel heating element, graphene possesses excellent electrical and thermal conductivity, resulting in higher heating efficiency, faster heating speed, and stronger radiation intensity compared to traditional metal heating elements. Applying graphene to cooking appliances allows for rapid food processing through thermal radiation, shortening cooking time and preserving the original flavor of the food.

[0087] Heating elements need to be securely and reliably fixed in electrical appliances to avoid damage from drops during transportation, and they also need to be easy and quick to install to meet production requirements. However, the flat sealing structure at both ends of the glass tube of graphene heating elements causes some inconvenience in installation. Therefore, this utility model proposes a fixing structure for heating elements.

[0088] The purpose of this embodiment is to propose a heating tube fixing structure, which has the advantages of convenient installation and reliable fixing. Specific implementation examples:

[0090] like Figure 1 and Figure 6 As shown, the heating element fixing structure includes a graphene heating element and a heat insulation plate (installed on cavity 1). The graphene heating element is inserted into an opening at one end of the heat insulation plate and exits through an opening at the other end. The heating element is then clamped and fixed from both sides by a fixing bracket. The support plates (flat parts) at both ends of the heating element are inserted into the corresponding slots of the fixing bracket. Finally, the fixing bracket is fixed to the heat insulation plate with screws, thereby restricting the displacement of the heating element in all directions.

[0091] like Figure 2 and Figure 3 As shown, the graphene heating element mainly consists of a glass tube and an internal heating wire, a heating element support plate, and a heating element connecting wire.

[0092] like Figure 4 and Figure 5 As shown, the main structure of the fixing bracket (used to fix the heating element) is a press-fit structure, used to hold the support plate of the heating element in place. The limiting hole (i.e., the insertion hole 39) is used to cooperate with the protrusion on the heat insulation plate (equivalent to the insertion protrusion 16) for limiting. The limiting baffle is used to restrict the lateral displacement of the heating element.

[0093] Figure 1 and Figure 6 Two schematic diagrams show the heating element fixing structure. The heating element has semi-cylindrical ceramic parts at both ends, and the fixing bracket has corresponding semi-circular holes. The displacement of the heating element is restricted by fitting the ceramic parts of the heating element into the bracket.
