However, these example embodiments can be implemented in various different forms and should not be construed as limited to only the embodiments set forth herein. It should be understood that the embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art, and in the drawings, the thicknesses of layers and regions are exaggerated for clarity, and the same reference numerals are used throughout the drawings and thus repeated descriptions are omitted.

[0049] In conjunction with Figures 1 to 9 As shown, according to specific embodiments of the present application, a baking tray assembly and an electric baking pan having the same are provided.

[0050] In particular, the baking tray assembly includes a baking tray 10 located on a mounting base, a heating pipe 20 disposed on the baking tray 10, and a fixing portion 30 at least partially connected with the baking tray 10, wherein a limiting space is formed between at least part of the fixing portion 30 and the baking tray 10, and at least part of the heating pipe 20 is arranged in the limiting space.

[0051] By applying the technical solution of this utility model, the heating element is connected to the baking pan via a fixing part, forming a limiting space. At least a portion of the heating element passes through this limiting space, ensuring the stability of the heating element and preventing displacement or damage during heating. Simultaneously, the fixing part ensures close contact between the heating element and the baking pan, allowing heat from the heating element to be directly transferred to the surface of the baking pan. This helps concentrate and retain heat, reduces heat loss, and improves the overall thermal energy utilization rate of the system. This application solves the problem in the prior art where limitations in materials and molding processes prevent the effective fixing of heating elements in iron and stainless steel baking pans.

[0052] In some alternative embodiments, the baking pan 10 has a receiving cavity 11, and the heating tube 20 is disposed in the receiving cavity 11.

[0053] In some alternative embodiments, the baking pan 10 is planar, and the heating tube 20 is connected to the planar surface of the baking pan 10.

[0054] Furthermore, the fixing part 30 includes a first fixing member 31, which is connected to the baking tray 10. The first fixing member 31 extends along the length direction of the heating tube 20, and a limiting space is formed between the first fixing member 31 and the baking tray 10.

[0055] like Figure 1 , Figure 3 As shown, the first fixing member 31 extends along the length of the heating tube 20, and a limiting space is formed between the first fixing member 31 and the baking tray 10. The limiting space formed by the first fixing member 31 and the baking tray 10 can provide stable support for the heating tube 20, reduce displacement caused by vibration or thermal expansion, and enhance the stability of the entire assembly.

[0056] In this embodiment, the first fixing member 31 is welded to the baking tray 10. In other embodiments, the connection method between the first fixing member 31 and the baking tray 10 is not limited to this. The first fixing member 31 and the baking tray 10 can also be integrally formed and the heating tube 20 can be passed through the limiting space. Alternatively, the first fixing member 31 and the baking tray 10 can be detachably connected, so as to facilitate the replacement of the fixing member.

[0057] In this embodiment, the first fixing member 31 is an iron sheet. In other embodiments, the material of the first fixing member 31 is not limited to this. For example, the first fixing member 31 can also be aluminum, copper, stainless steel, etc.

[0058] Furthermore, the fixing part 30 includes at least one of the following: a second fixing member 32, a third fixing member 33, a fourth fixing member 34, a fifth fixing member 35, a sixth fixing member 36, and a seventh fixing member 37. The second fixing member 32, the third fixing member 33, the fourth fixing member 34, the fifth fixing member 35, the sixth fixing member 36, and the seventh fixing member 37 are made of metal.

[0059] The metal fixing member has high strength and rigidity, which can ensure the stability of the baking tray 10 and the heating pipe 20 during work, and reduce displacement caused by thermal expansion or mechanical vibration. The high melting point and high temperature resistance of the metal fixing member help maintain the integrity of the structure in a high temperature working environment, thereby ensuring the safety performance of the entire assembly.

[0060] Further, the fixing part 30 includes a plurality of second fixing members 32, the plurality of second fixing members 32 are arranged at intervals along the length direction of the heating pipe 20, each second fixing member 32 covers part of the heating pipe 20 along the circumferential direction of the heating pipe 20, and both ends of each second fixing member 32 are connected with the baking tray 10.

[0061] Specifically, the plurality of second fixing members 32 are arranged at intervals along the length direction of the heating pipe 20, which can provide more uniform support for the heating pipe and reduce deformation or damage caused by excessive local stress. By covering part of the heating pipe with the second fixing member 32 and connecting both ends of the second fixing member 32 with the baking tray 10, the fixing stability of the heating pipe 20 is enhanced, preventing displacement or vibration during work. This design can adapt to heating pipes 20 of different lengths to meet the needs of different application scenarios. Multiple fixing points help to disperse the thermal stress generated by the heating pipe during work, avoiding rupture or leakage caused by stress concentration.

[0062] In this embodiment, as shown in Figure 4 , the second fixing member 32 is five, in other embodiments, the number of second fixing members 32 is not limited to this, the number of second fixing members 32 can be adaptively adjusted according to the length of the heating pipe 20, for example, the number of second fixing members 32 can also be set to three, six, etc.

[0063] In this embodiment, the second fixing member 32 is welded with the baking tray 10, in other embodiments, the connection mode of the second fixing member 32 with the baking tray 10 is not limited to this, the second fixing member 32 can also be integrally formed with the baking tray 10, and the heating pipe 20 can be sequentially inserted through the limiting space, and the first fixing member 31 can also be detachably connected with the baking tray 10, thereby facilitating replacement of the fixing member.

[0064] As shown in Figure 6 , the fixing part 30 includes a third fixing member 33, the third fixing member 33 includes: an iron sheet 331, the iron sheet 331 is at least two, the at least two iron sheets 331 are symmetrically arranged along the radial direction of the heating pipe 20, the first end of each iron sheet 331 is connected with the baking tray 10, the second end of each iron sheet 331 abuts against the outer circumferential surface of the heating pipe 20, a through hole is arranged on the second end of the iron sheet 331, a limiting member 332 is arranged in the through hole, and the limiting member 332 abuts against the outer circumferential surface of the heating pipe 20.

[0065] By symmetrically arranging the at least two iron sheets 331 in the radial direction of the heating pipe 20, the fixing force can be more evenly distributed, avoiding deformation or damage of the heating pipe 20 due to pressure concentration. The first end of the iron sheet 331 is connected with the baking tray 10, and the second end abuts against the outer circumferential surface of the heating pipe 20 and abuts against the outer circumferential surface of the heating pipe 20 through the limiting piece 332 in the through hole. Such a structure can improve the fixing stability of the heating pipe, reduce vibration or displacement during work, and facilitate installation and adjustment of the position of the iron sheet 331 to adapt to heating pipes 20 of different sizes, improving the versatility and flexibility of the fixing piece.

[0066] As shown in Figure 6 , the fixing part 30 includes a fourth fixing piece 34, which includes at least two connecting columns 342 arranged on both sides of the heating pipe 20 in the radial direction of the heating pipe 20, and the first end of each connecting column 342 is connected with the baking tray 10. The limiting plate 341 is connected with the second end of each connecting column 342, and the limiting plate 341 is located outside the heating pipe 20, and the at least two connecting columns 342 and the limiting plate 341 and the baking tray 10 form a limiting space.

[0067] By connecting the limiting plate 341 with the baking tray 10 through at least two connecting columns 342, a stable fixing structure is formed, which enhances the stability and rigidity of the entire assembly. The connecting column 342, the limiting plate 341 and the baking tray 10 form a limiting space, which can effectively limit the heating pipe 20 in the radial direction and prevent displacement during work.

[0068] Further, at least two of the second fixing piece 32, the third fixing piece 33 and the fourth fixing piece 34 can be used in combination. By using a combination of multiple fixing pieces, the heating pipe 20 can be fixed from different directions and angles, thereby significantly improving the stability and rigidity of the entire system. Different fixing pieces can provide multiple fixing methods, so that the heating pipe 20 can be effectively fixed and supported in different positions and under different conditions.

[0069] In one embodiment, as shown in Figure 2 , the second fixing piece 32, the third fixing piece 33 and the fourth fixing piece 34 act on the heating pipe 20 simultaneously to fix the heating pipe 20.

[0070] In another embodiment, as shown in Figure 5 , the third fixing piece 33 and the fourth fixing piece 34 act on the heating pipe 20 simultaneously to fix the heating pipe 20.

[0071] Further, the fifth fixing member 35 comprises a first support member 352 connected with the baking tray, and a first limiting member 351 having a first end fixedly connected with the first support member 352 and a second end arranged away from the first support member 352, and the first limiting member 351 and the first support member 352 form a limiting space with the baking tray, and at least part of the heating pipe 20 is arranged in the limiting space.

[0072] As shown in Figure 8 the first support member 352 is connected with the baking tray 10 along the length direction of the heating pipe 20 to limit the movement range of the heating pipe 20, and the first support member 352 can be generally a flat metal sheet which is firmly combined with the baking tray 10 by welding or screws to ensure the stability of the fifth fixing member 35 during the whole use of the baking tray. The first limiting member 351 and the first support member 352 form a limiting space with the baking tray, and by this design, the heating pipe 20 can be stably limited in the limiting space to ensure the position stability during use. The adjustment ability of the first support member 352 enables the position of the heating pipe 20 to be finely adjusted according to the heating demand, so as to optimize the heating uniformity and improve the efficiency and effect of the baking tray 10.

[0073] Specifically, the first limiting member 351 comprises a first component segment and a second component segment, the first end of the first component segment is integrally formed with the first support member 352, the first end of the second component segment is connected with the second end of the first component segment and arranged at an angle, and the second end of the second component segment is arranged away from one side of the first limiting member 351 and abuts against the heating pipe 20 on the side facing the baking tray 10.

[0074] The first end of the first component segment is integrally formed with the first support member 352, which can improve the strength and stability of the whole fixing structure, reduce the possible failure points due to too many connection points, and further save the processing cost. The second end of the second component segment is arranged away from one side of the first limiting member 351, and the second end of the second component segment abuts against the heating pipe 20 on the side facing the baking tray 10. The second component segment abuts against the heating pipe 20 to further limit the movement of the heating pipe 20 in the radial direction, so that the heating pipe 20 is better fixed. Specifically, the angle formed by the first end of the second component segment and the second end of the first component segment is a right angle.

[0075] In this embodiment, the first end of the second component segment and the second end of the first component segment are connected to form a right angle, and the first limiting piece is in an L-shaped arrangement. Compared with other angles, the right angle structure can provide better structural stability. This design can increase the contact area between the first limiting piece 351 and the first supporting piece 352, thereby improving the connection strength between the two components. The rigid structure formed by the right angle connection helps to enhance the bending strength of the entire fifth fixing piece 35, avoid deformation during use, and prolong the service life of the baking tray 10.

[0076] Further, the sixth fixing piece 36 includes: a second supporting piece 362, which is located on the same side of the heating pipe 20 as the first supporting piece 352, and is connected with the baking tray; a second limiting piece 361, one end of which is connected with the second supporting piece 362 through a first connecting piece 363, and the other end of which is arranged away from the second supporting piece 362, and the second limiting piece 361 and the second supporting piece 362 form a limiting space with the baking tray, and at least part of the heating pipe 20 is arranged in the limiting space.

[0077] The second supporting piece 362 and the first supporting piece 352 are located on the same side of the baking tray, which means that they are both on the bottom or side of the baking tray, and together provide support for the heating pipe 20. The second supporting piece 362 is tightly connected with the baking tray 10 through welding, riveting, screw fixing or other connection methods, and its function is to firmly fix the entire sixth fixing piece 36 on the baking tray 10.

[0078] As shown in Figure 8 The second supporting piece 362 is provided with a through hole, and the end of the second limiting piece 361 connected with the second supporting piece 362 is also provided with a through hole. The through holes on the second supporting piece 362 and the second limiting piece 361 are arranged one by one, and the first connecting piece 363 passes through the two through holes to detachably connect the second supporting piece 362 and the second limiting piece 361. In this embodiment, the first connecting piece can use a screw, and the first connecting piece 363 (such as a screw) connects the second limiting piece 361 and the second supporting piece 362, making the installation and disassembly of the sixth fixing piece 36 relatively easy. This design provides convenience for later maintenance and replacement of the heating pipe.

[0079] The second limiting piece 361, the second supporting piece 362 and the baking tray form a limiting space, which limits the position of the heating pipe 20, prevents displacement caused by thermal expansion and contraction of the heating pipe 20 during heating and cooling, and ensures correct contact between the heating pipe 20 and the baking tray 10, thereby improving the uniformity of the heating effect and the safety of the baking tray.

[0080] Further, the seventh fixing member 37 comprises: at least two third support members 372, which are arranged on both sides of the heating pipe 20 along the radial direction of the heating pipe 20 and connected with the baking tray; and a third limiting member 371, two ends of which are connected with corresponding third support members 372 through a second connecting member 373 respectively, and the third limiting member 371, the at least two third support members 372 and the baking tray form a limiting space, and at least part of the heating pipe 20 is arranged in the limiting space.

[0081] As shown in Figure 9 the at least two third support members 372 are arranged on both sides of the heating pipe 20 along the radial direction of the heating pipe 20 and connected with the baking tray along the length direction of the heating pipe; the third support members 372 are tightly connected with the baking tray through welding, screw fixing or other connecting modes, so as to ensure the stability of the whole fixing member structure. In the embodiment, two third support members 372 are arranged on both sides of the heating pipe 20 along the radial direction of the heating pipe 20, and the moving range of the heating pipe is limited between the two third support members 372, so as to limit the movement of the heating pipe in the horizontal direction.

[0082] The two ends of the third limiting member 371 are connected with corresponding third support members 372 through a second connecting member 373 respectively, so as to improve the overall strength and durability of the fixing structure. The second connecting member 373 can be a screw, a rivet or a welding point, which is used to firmly fix the third limiting member 371 on the third support member 372. The third limiting member 371 is arranged and connected in such a mode that it can cross the heating pipe 20 and form a top limiting, so as to prevent the movement of the heating pipe in the vertical direction.

[0083] The use of the second connecting member 373 (such as a screw) makes the connection between the third limiting member 371 and the third support member 372 more flexible, facilitates the installation and disassembly of the seventh fixing member 37, and is beneficial to the replacement of the heating pipe and the maintenance of the baking tray.

[0084] The seventh fixing member 37 forms a limiting space between the third limiting member 371 and the at least two third support members 372 and the baking tray, so as to provide a stable fixing environment for the heating pipe 20. The heating pipe 20 is at least partially arranged in the limiting space, so as to ensure the position stability of the heating pipe during the heating process and not to be affected by factors such as thermal expansion.

[0085] The seventh fixing member 37 can adapt to heating pipes with different diameters and baking trays with different materials and shapes through the design of the two third support members 372. By adjusting the distance between the third support members 372 and the size of the third limiting member 371, the effective fixation of the heating pipe on various baking trays can be ensured.

[0086] Specifically, the baking tray 10 is made of one of stainless steel, iron, and cast aluminum. The iron baking tray and the stainless steel baking tray cannot use the fixing groove of the heating pipe to fix the heating pipe due to the limitation of the material forming process. The fixing mode in the embodiment has no limitation on the material of the baking tray 10, and the baking tray 10 in the embodiment can be made of any one of stainless steel, iron, and cast aluminum.

[0087] In one of the embodiments, as shown in Figure 7 The fifth fixing member 35, the sixth fixing member 36, and the seventh fixing member 37 simultaneously act on the heating pipe 20 to fix the heating pipe 20.

[0088] In an optional embodiment, the second fixing member 32, the third fixing member 33, the fourth fixing member 34, the fifth fixing member 35, the sixth fixing member 36, and the seventh fixing member 37 can be used alone to fix the heating pipe 20 or can be freely combined and used to fix the heating pipe 20.

[0089] Further, the fixing part 30 is welded with the baking tray 10, or the fixing part 30 is detachably connected with the baking tray 10. The welding can realize the firm connection between the fixing part 30 and the baking tray 10, and improve the stability and carrying capacity of the whole structure. The detachable connection enables the fixing part 30 and the baking tray 10 to be quickly separated when maintenance or replacement is needed, without the need for a complex disassembly process, thereby saving maintenance time and cost.

[0090] From the above description, it can be seen that the embodiments of the utility model realize the following technical effects:

[0091] The fixing part 30 is connected with the baking tray 10 and surrounds the limiting space, so that at least part of the heating pipe 20 is arranged in the limiting space, the stability of the heating pipe is ensured, displacement or damage of the heating pipe during heating is prevented, the fixing part 30 helps to concentrate and maintain heat, reduces heat loss, and improves the heat energy utilization rate of the whole system.
