Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a reflector and an electric baking pan. Background Technology

[0002] The reflectors of cooking equipment such as electric baking pans are usually designed as a single piece. For example, the reflector is made by stamping, and its edges are formed by bending to form multiple flanges, some of which are fixedly connected to the equipment shell.

[0003] However, due to the molding process of the reflector, adjacent flanges are usually disconnected, resulting in insufficient overall strength of the reflector. Structural stability is only maintained by the flanges connected to the equipment housing. Therefore, after assembly, the reflector is prone to significant wobbling, affecting its operational stability. Utility Model Content

[0004] Therefore, it is necessary to provide a reflector and an electric baking pan to address the above problems and improve the stability of the reflector in use.

[0005] This utility model first provides a reflective element, comprising: a plate; flanges integrally formed and bent to the edge of the plate, wherein the number of flanges is at least two and each flange is arranged circumferentially along the plate; and a connecting part, wherein the number of connecting parts is at least one and each connecting part fixes any two adjacent flanges together.

[0006] In the aforementioned reflector, two adjacent flanges are fixedly connected by a connecting part, allowing the adjacent flanges to support each other, thereby improving the overall strength of the reflector. When the reflector is fixedly connected to the housing of an electric baking pan or other equipment via some of the flanges, the stability of the reflector can be maintained not only by the flanges directly connected to the equipment housing, but also by the adjacent flanges connected by the connecting part, thereby reducing the shaking of the reflector during use and improving the overall stability of the reflector.

[0007] In one embodiment, the flange includes an adjacent first flange and a second flange, one end of the connecting portion is integrally formed and bent to the end of the first flange near the second flange, and the other end of the connecting portion is fixedly connected to the second flange.

[0008] With this setup, a one-piece plate structure can be formed first through stamping, and then the edges of the plate structure can be bent through bending to form a first flange, a second flange, and a connecting part. Finally, the connecting part is fixedly connected to the second flange. The processing method of the reflector is simple, the number of parts is small, and the cost is low.

[0009] In one embodiment, the outer surface of the connecting portion is fixedly connected to the inner surface of the second flange; or the inner surface of the connecting portion is fixedly connected to the outer surface of the second flange.

[0010] With this configuration, the connecting part and the second flange are fixedly connected through surface contact, which can increase the contact area between the two and improve the stability and reliability of the connection; in addition, it can also increase the overall thickness of the connecting part and the second flange, and improve the strength of the connection between the two.

[0011] In one embodiment, the thickness of both the connecting portion and the second flange is between 0.5 mm and 0.7 mm, and the distance between the inner surface of the connecting portion and the inner surface of the second flange is between 0.9 mm and 1 mm.

[0012] With this configuration, during the process of bending the edges of the plate-like structure to form the first flange, the second flange, and the connecting part, the connecting part will not collide or interfere with the second flange, thus ensuring that the reflector can be bent and formed smoothly.

[0013] In one embodiment, the connecting portion is fixed to the second flange by fasteners or welding.

[0014] This design ensures the stability and reliability of the connection between the connecting part and the second flange.

[0015] In one embodiment, there are two first flanges, which are arranged opposite to each other, and both ends of each first flange are connected to the adjacent second flange through the connecting portion.

[0016] This design improves the overall strength and stability of the reflector.

[0017] This utility model also provides an electric baking pan, including the reflector as described above.

[0018] In one embodiment, the electric baking pan further includes a pan body and a plurality of legs disposed at the bottom of the pan body, the plurality of legs being arranged at circumferential intervals along the pan body, and the flange of the reflector being fixedly connected to the legs by fasteners.

[0019] With this configuration, the feet are used to support the pan body, and the reflector is used to reflect the heat radiated by the heating element of the electric baking pan towards the bottom back to the pan body.

[0020] In one embodiment, the flange includes an adjacent first flange and a second flange, one end of the connecting part is integrally formed and bent to the end of the first flange near the second flange, and the other end of the connecting part and the second flange are fixedly connected to the support leg by fasteners.

[0021] This design allows the connecting part, the second flange, and the support leg to be fixedly connected by a set of fasteners, simplifying the assembly steps of the reflector, reducing the number of parts, and improving assembly efficiency.

[0022] In one embodiment, the electric baking pan includes a first reflector and a second reflector arranged at intervals along the height direction of the electric baking pan, wherein at least one of the first reflector and the second reflector is the reflector.

[0023] With this configuration, the first and second reflectors can improve the heat reflection effect, and when both the first and second reflectors are reflective elements, the overall stability of the electric baking pan can be improved. Attached Figure Description

[0040] Reflectors in cooking appliances such as electric baking pans are typically designed as a single piece, such as a stamped reflector with multiple flanges formed by bending the edges. Some of these flanges are fixedly connected to the appliance housing. However, due to the molding process, adjacent flanges are often disconnected, resulting in insufficient overall strength of the reflector. The structural stability relies solely on the flanges connected to the appliance housing. Consequently, after assembly, the reflector is prone to noticeable wobbling, affecting its stability during use.

[0041] To solve the above problems, such as Figures 1 to 9 As shown, this utility model provides a reflector and an electric baking pan to improve the stability of the reflector in use.

[0042] like Figures 1 to 2 As shown, specifically, the reflector 10 includes a plate 11, a flange 12, and a connecting part 13, wherein: the flange 12 is integrally formed with the edge of the plate 11 and bent and connected, the number of flanges 12 is at least two, and each flange 12 is arranged along the circumference of the plate 11; the number of connecting parts 13 is at least one, and each connecting part 13 fixes any two adjacent flanges 12 together.

[0043] In the reflector 10 provided in this embodiment of the utility model, two adjacent flanges 12 are fixedly connected by the connecting part 13, so that the adjacent flanges 12 can support each other, thereby improving the overall strength of the reflector 10. When the reflector 10 is fixedly connected to the housing of an electric baking pan or other equipment through part of the flanges 12, the stability of the reflector 10 can be maintained not only by the flanges 12 directly connected to the equipment housing, but also by the adjacent flanges 12 connected by the connecting part 13, thereby reducing the shaking of the reflector 10 during use and improving the overall stability of the reflector 10.

[0044] like Figure 2 and Figure 5As shown, in one embodiment, the flange 12 includes adjacent first flange 121 and second flange 122. One end of the connecting portion 13 is integrally formed and bent to the end of the first flange 121 near the second flange 122, and the other end of the connecting portion 13 is fixedly connected to the second flange 122. When processing the reflector 10, it can first be formed into an integral plate structure by stamping, and then the edges of the plate structure can be bent to form the first flange 121, the second flange 122 and the connecting portion 13 by bending, and finally the connecting portion 13 is fixedly connected to the second flange 12. In this way, the processing method of the reflector 10 is simple, the number of parts is small, and the cost is low.

[0045] In another embodiment, the connecting part 13 can also be set as a separate structure from the first flange 121. When processing the reflector 10, the plate-shaped structure and the separate connecting part 13 are first formed by stamping. Then, the edge of the plate-shaped structure is bent to form the first flange 121 and the second flange 122 by bending. Finally, the two ends of the connecting part 13 are fixedly connected to the first flange 121 and the adjacent second flange 122 respectively.

[0046] In this embodiment, at least a portion of the first flange 121 may be fixedly connected to the device housing, or at least a portion of the second flange 122 may be fixedly connected to the device housing, or at least a portion of the first flange 121 and at least a portion of the second flange 122 may be fixedly connected to the device housing together. The specific connection can be adjusted according to the structure of the reflector 10 and the device. This embodiment of the present invention does not impose any specific limitations.

[0047] like Figure 2 As shown, in one embodiment, the connecting part 13 and the second flange 122 can be fixed by fasteners such as screws and bolts to ensure the stability and reliability of the connection between the connecting part 13 and the second flange 122. When the second flange 122 is used to fix the connection to the housing of an electric baking pan or other equipment, the same set of fasteners can be used to fix the connecting part 13 and the second flange 122 to the equipment housing at the same time; alternatively, a set of fasteners can be used to fix the connecting part 13 and the second flange 122 first, and then another set of fasteners can be used to fix the second flange 122 to the equipment housing.

[0048] Of course, in other embodiments, the connecting part 13 and the second flange 122 can also be fixed by welding, gluing or other methods, as long as the stability and reliability of the connection between the connecting part 13 and the second flange 122 can be guaranteed. This utility model embodiment does not make specific limitations here.

[0049] like Figures 2 to 3As shown, in one embodiment, the outer surface of the connecting portion 13 is fixedly connected to the inner surface of the second flange 122. The outer surfaces of both the connecting portion 13 and the second flange 122 refer to their sides facing away from the plate body 11, while the inner surfaces of both refer to their sides facing the plate body 11. Thus, the connecting portion 13 and the second flange 122 are fixedly connected through surface contact, which increases the contact area between them, improving the stability and reliability of the connection; furthermore, it also increases the overall thickness of the connecting portion 13 and the second flange 122, improving the strength of the connection.

[0050] At this point, since the thickness of the integral plate structure formed by stamping is generally between 0.5mm and 0.7mm, the thickness L1 of both the connecting part 13 and the second flange 122 is between 0.5mm and 0.7mm. Furthermore, the distance L2 between the inner surface of the connecting part 13 and the inner surface of the second flange 122 is between 0.9mm and 1mm, ensuring that the distance L3 between the outer surface of the connecting part 13 and the inner surface of the second flange 122 is between 0.2mm and 0.5mm. Thus, during the bending process to form the first flange 121, the second flange 122, and the connecting part 13, the connecting part 13 will not collide or interfere with the second flange 12, thereby ensuring that the reflector 10 can be smoothly bent and formed.

[0051] like Figures 5 to 6 As shown, in the integral plate structure formed by stamping, the bending line a between the connecting part 13 and the first flange 121 is parallel to the bending line b between the second flange 122 and the plate 11 and is located inside the bending line b. The distance between the bending line a and the bending line b is L2, which satisfies 0.9mm to 1mm.

[0052] like Figure 4 As shown, in another embodiment, the inner surface of the connecting portion 13 is fixedly connected to the outer surface of the second flange 122. In this case, the thickness L1 of both the connecting portion 13 and the second flange 122 is 0.5mm to 0.7mm, the distance L2 between the inner surface of the connecting portion 13 and the inner surface of the second flange 122 is 0.9mm to 1mm, and the distance L3 between the inner surface of the connecting portion 13 and the outer surface of the second flange 122 is 0.2mm to 0.5mm. In the integral plate structure formed by stamping, the bending line a between the connecting portion 13 and the first flange 121 is parallel to and located outside the bending line b between the second flange 122 and the plate 11, and the distance between bending line a and bending line b is L2, which is 0.9mm to 1mm.

[0053] like Figure 1As shown, in one embodiment, there are two first flanges 121 arranged opposite to each other, and four second flanges 122 adjacent to the ends of the two first flanges 121. Both ends of each first flange 121 are connected to the adjacent second flange 122 via a connecting portion 13, thereby improving the overall strength and stability of the reflector 10. Alternatively, only some ends of the first flanges 121 may be connected to the adjacent second flanges 122 via the connecting portion 13.

[0054] In another embodiment, the reflector 10 is generally square, with two first flanges 121 and two second flanges 122. The two first flanges 121 are arranged opposite each other, and the two second flanges 122 are arranged opposite each other. Both ends of each first flange 121 are connected to the adjacent second flange 122 through a connecting portion 13. Alternatively, only the ends of some of the first flanges 121 may be connected to the adjacent second flanges 122 through the connecting portion 13.

[0055] Of course, in other embodiments, the number of first flanges 121 can be one, three, four or more, and the number of second flanges 122 can be one, two, three, four, five or more. The number of first flanges 121 and second flanges 122 can be adjusted according to the structure of the reflector 10 and the device. This embodiment of the present invention does not impose specific limitations here.

[0056] like Figures 7 to 8 As shown, this embodiment of the present invention also provides an electric baking pan, including the aforementioned reflector 10. The electric baking pan further includes a pan body 20 and multiple legs 30 disposed at the bottom of the pan body 20. The multiple legs 30 are arranged at intervals along the circumference of the pan body 20. The flange 12 of the reflector 10 is fixedly connected to the legs 30 by fasteners. The legs 30 are used to support the pan body 20, allowing it to be stably mounted on an external surface such as a tabletop. The reflector 10 is fixedly connected to the legs 30 and disposed at the bottom of the pan body 20. The reflector 10 is used to reflect the heat radiated by the heating element (not shown) of the electric baking pan towards the bottom back to the pan body 20, thereby reducing energy loss and improving heating efficiency. The number of legs 30 can be four as shown in the figure, or two, three, five, or more. The specific number can be adjusted according to the structure of the electric baking pan, as long as the stability of the legs 30 supporting the pan body 20 is ensured. This embodiment of the present invention does not impose specific limitations here.

[0057] like Figures 8 to 9As shown in the illustrated embodiment, the connecting part 13 and the second flange 122 are together fixedly connected to the support leg 30 by fasteners such as screws and bolts. Thus, the connecting part 13, the second flange 122, and the support leg 30 can be fixedly connected by a single set of fasteners, simplifying the assembly steps of the reflector 10, reducing the number of parts, and improving assembly efficiency. The shape of the second flange 122 can be adapted to the shape of the support leg 30, allowing the second flange 122 to fit snugly against the support leg 30, increasing the contact area between the second flange 122 and the support leg 30, and improving the stability and reliability of the connection between the reflector 10 and the support leg 30. Of course, in other embodiments, the connecting part 13 and the second flange 122 can be fixedly connected first by fasteners, welding, adhesive, etc., and then the first flange 121 or the second flange 122 can be fixedly connected to the support leg 30 by fasteners such as screws and bolts.

[0058] like Figure 7 As shown, the electric baking pan also includes handles 60 disposed on both sides of the pan body 20, allowing the user to move the electric baking pan by gripping the handles 60. In the illustrated embodiment, the second flange 122 is disposed on both sides of the plate body 11 corresponding to the handles 60, and the connecting part 13 and the second flange 122 are together fixedly connected to the support leg 30 by fasteners such as screws and bolts. In this way, the strength and stability of the reflector 10 on both sides of the handles 60 can be further improved, reducing the shaking of the reflector 10 inside the electric baking pan during the user's movement of the electric baking pan. In other embodiments, the first flange 121 may also be disposed on both sides of the plate body 11 corresponding to the handles 60.

[0059] like Figures 7 to 8 As shown, in one embodiment, the electric baking pan includes a first reflector 40 and a second reflector 50 arranged at intervals along the height direction of the electric baking pan. Both the first reflector 40 and the second reflector 50 are reflective elements 10 to improve the overall stability of the electric baking pan. The stacked arrangement of the first reflector 40 and the second reflector 50 can improve the heat reflection effect and further reduce energy loss. Other structures such as the baking pan and heating elements can also be added between the first reflector 40 and the second reflector 50 as needed. In other embodiments, only one of the first reflector 40 and the second reflector 50 may be a reflective element 10, while the other may be a reflector with other structures; alternatively, the number of reflectors in the electric baking pan may be one, three, four, or more, which can be adjusted according to the structure of the electric baking pan. This embodiment of the present invention does not impose specific limitations.

[0060] Of course, the reflector 10 can also be used in other cooking equipment such as ovens and grills.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
