[0032] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0033] According to an embodiment of the present invention, in one aspect, a heat preservation rack 1 assembly is provided, including multiple heat preservation racks 1, which are adapted to be spliced ​​sequentially in a front-to-back direction; each heat preservation rack 1 includes a frame 11, a connecting part is provided on the rear side of the frame 11, and a first mounting part 161 is provided on the front side of the frame 11. When multiple heat preservation racks 1 are spliced ​​sequentially in a front-to-back direction, in two adjacent heat preservation racks 1, the connecting part on the front heat preservation rack 1 is detachably connected to the first mounting part 161 on the rear heat preservation rack 1.

[0034] The warming rack 1 component of this structure is used in an oven, which includes an oven body 3 and a main burner. The main burner is located inside the oven body 3. According to usage requirements, multiple warming racks 1 can be sequentially spliced ​​along the front-back direction of the oven body 3. The warming racks 1 facing the rear side wall of the oven body 3 are connected to the rear side wall of the oven body 3 through connecting parts. Along the front-back direction of the oven body 3, some warming racks 1 can extend towards the front side of the oven body 3 to the upper part of the middle area of ​​the oven body 3. The residual heat of the main burner in this area is relatively high, so this part of the heat can be fully utilized to keep the food on the warming rack 1 warm, which can improve heat utilization and heat preservation effect, and ensure the taste and flavor of the grilled food, which is conducive to improving the user experience. Furthermore, some warming racks 1 extend to the middle area of ​​the oven body 3 in the front-back direction. Food placed on the warming rack 1 above the middle area can be grilled or smoked over a low flame using the main burner, which can meet the user's grilling needs for different types of food. Alternatively, the insulation rack 1 can be placed on one side of the length of the oven body 3, allowing users to perform grilling operations on the other side of the length of the oven body 3. This effectively avoids the insulation rack 1 obstructing the user's operation and improves the convenience of grilling operations.

[0035] like Figure 1 As shown, in some embodiments, when multiple insulation racks 1 are spliced ​​sequentially in the front-to-back direction, the connecting part on the front insulation rack 1 is inserted into the first mounting part 161 on the rear insulation rack 1. This facilitates the assembly and disassembly of the insulation rack 1, effectively improving the assembly and disassembly efficiency of multiple insulation racks 1, and making it convenient for users to assemble, disassemble, or add or remove insulation racks 1 according to the on-site usage requirements.

[0036] like Figure 1 As shown, optionally, the first mounting part 161 includes a mounting hole, and the connecting part includes a hook part 12. When multiple insulation racks 1 are sequentially spliced ​​in the front-to-back direction, the hook part 12 on the front insulation rack 1 is inserted into the mounting hole on the rear insulation rack 1. The hook part 12 is inserted into the mounting hole, making the insertion and connection structure simple and reliable, which is conducive to the user's convenient and quick assembly and disassembly of the insulation rack 1 on site.

[0037] like Figure 1 As shown, in some embodiments, the warming rack 1 further includes a support plate 13 and an abutment plate 14. The support plate 13 is located on the front side of the rack body 11 and extends downward, while the abutment plate 14 is located on the rear side of the rack body 11 and extends upward. When multiple warming racks 1 are sequentially spliced ​​in the front-to-back direction, the abutment plate 14 on the front warming rack 1 abuts against the support plate 13 on the rear warming rack 1. A connecting part is provided on the abutment plate 14. The front and rear warming racks 1 are engaged with the mounting holes through hook parts 12. When food is placed on the rack body 11, the rack body 11 is subjected to force, which may affect the stability of the warming rack 1 assembly. After the support plate 13 and the abutment plate 14 are set, the abutment plate 14 on the front side of the heat preservation rack 1 abuts against the support plate 13 on the rear side of the heat preservation rack 1. The support plate 13 can support the abutment plate 14 on the front side from the rear side, which helps to improve the overall stability of the heat preservation rack 1 assembly, keep the rack 11 in a horizontal state, prevent the front end of the rack 11 from tilting downward, and help the heat preservation rack 1 stably support the food after grilling.

[0038] like Figure 1 As shown, the abutment plate 14 is located on the upper rear side of the frame 11, and the support plate 13 is located on the lower front side of the frame 11. The support plate 13 is parallel to the abutment plate 14, so that when multiple insulation racks 1 are spliced ​​together, the support plate 13 on the rear insulation rack 1 can be completely attached to the abutment plate 14 on the front insulation rack 1, which can improve the support effect of the support plate 13 on the abutment plate 14 and further enhance the overall stability of the multiple insulation racks 1 spliced ​​together.

[0039] In some embodiments, the height of the abutment plate 14 is greater than or equal to the height of the support plate 13, and the frame 11 is located at the bottom of the abutment plate 14. To ensure the heat preservation effect of the food on the frame 11, the height between the frame 11 and the main burner below it cannot be too high. When the heat preservation rack 1 assembly is installed on the rear side wall of the furnace body 3, when the installation height of the heat preservation rack 1 facing the rear side wall of the furnace body 3 is fixed, the height of the frame 11 near the rear side wall of the furnace body 3 is determined by the height of the abutment plate 14. Therefore, the height of the abutment plate 14 cannot be too small, so that the height of the abutment plate 14 is greater than or equal to the height of the support plate 13. This ensures that the abutment plate 14 has sufficient height, thereby ensuring that the height of the frame 11 from the main burner is not too large, and thus ensuring the heat preservation effect of the heat preservation rack 1.

[0040] Optionally, in some embodiments, the height of the abutment plate 14 is greater than the height of the support plate 13. This can prevent the frame 11 facing the rear side wall of the furnace body 3 from being too high from the main furnace head, and can also prevent the frame 11 at the front from being too close to the main furnace head when multiple insulation frames 1 are spliced ​​together. At the same time, while ensuring the stability of multiple insulation frames 1 after assembly, the material of the support plate 13 can be saved.

[0041] In some embodiments, the height of the support plate 13 is greater than or equal to 10 mm. This can prevent the height of the support plate 13 from being too small, ensure the support of the support plate 13 on the abutment plate 14, and help improve the stability of multiple insulation racks 1 after assembly.

[0042] like Figure 1 and Figure 3 As shown, in some embodiments, the warming rack 1 further includes an inclined plate 15. One end of the inclined plate 15 is connected to the front side of the rack body 11, and the other end of the inclined plate 15 is inclined upward in a direction away from the abutment plate 14. The other end of the inclined plate 15 is connected to the support plate 13. The inclined plate 15 is inclined at the front end of the rack body 11, which can shield the food placed on the rack body 11 and prevent the food from falling from the front end of the rack body 11. At the same time, the inclined plate 15 is structurally beneficial to improving the overall strength of the warming rack 1.

[0043] like Figure 3 As shown, the hook portion 12 includes a bending section 121 and a plug-in section 122. One end of the bending section 121 is connected to the upper end of the abutment plate 14, and the other end of the bending section 121 extends away from the frame 11 and is connected to the plug-in section 122. The end of the plug-in section 122 away from the bending section 121 extends downward, and the hook portion 12 is plugged into the mounting hole through the plug-in section 122.

[0044] like Figure 1 and Figure 3As shown, in some embodiments, the insulation rack 1 further includes a mounting plate 16. The inclined plate 15 is connected to the support plate 13 through the mounting plate 16. One end of the mounting plate 16 is connected to the other end of the inclined plate 15, and the other end of the mounting plate 16 extends away from the abutment plate 14 and is connected to the support plate 13. Mounting holes are provided on the mounting plate 16. When multiple insulation racks 1 are spliced ​​sequentially in the front-to-back direction, the bent section 121 of the hook portion 12 on the front insulation rack 1 abuts against the top surface of the mounting plate 16 on the rear insulation rack 1. After the hook portion 12 is inserted into the mounting hole, the bent section 121 abuts against the mounting plate 16. The mounting plate 16 can support the bent section 121 from below, which helps the hook portion 12 to be stably held on the mounting plate 16 and can improve the stability of the plug-in structure connection.

[0045] Alternatively, in some embodiments, such as Figure 1 As shown, the mounting holes are strip-shaped holes. Along the length of the furnace body 3, each mounting plate 16 has two strip-shaped holes spaced apart. Correspondingly, each abutment plate 14 has two hook portions 12.

[0046] like Figures 1 to 5 As shown, the insulation rack 1 assembly also includes a mounting bracket 2. The mounting bracket 2 has multiple second mounting portions 21 spaced along its length. Multiple insulation racks 1 are suitable for sequential splicing along the length of the mounting bracket 2. When multiple insulation racks 1 are sequentially spliced ​​along the length of the mounting bracket 2, the connecting portion is detachably connected to the second mounting portion 21. During installation, the mounting bracket 2 is fixed to the furnace body 3, and then the connecting portion of the insulation rack 1 is detachably connected to the second mounting portion 21. This facilitates the installation of the insulation rack 1 assembly and the furnace body 3 without altering the furnace body 3's structure. The insulation rack 1 assembly is installed on the furnace body 3 via the mounting bracket 2, and can be used in different ovens. The length of the mounting bracket 2 extends in the same direction as the length of the furnace body 3. Depending on actual usage requirements, different numbers of insulation racks 1 can be assembled along the length of the mounting bracket 2, or the insulation racks 1 can be installed at different positions along the length of the mounting bracket 2. The insulation rack 1 and the mounting bracket 2 are detachably connected, which makes it convenient to install and remove the insulation rack 1, and also makes it convenient for users to replace and clean the insulation rack 1.

[0047] The insulation rack 1 assembly can be assembled in different numbers along the length of the mounting bracket 2, or along the front and rear direction of the oven body 3. The number of insulation racks 1 can be increased or decreased as needed, effectively improving the flexibility of use and meeting the personalized needs of different users. Furthermore, multiple insulation racks 1 are of the same size and structure, and can be stacked vertically, reducing storage space and simplifying packaging. Different numbers of insulation racks 1 can be used in ovens of different sizes, making them versatile and reducing mold costs and manufacturing costs.

[0048] like Figure 3 and Figure 4 As shown, the mounting bracket 2 includes a top plate, a side plate, and a bottom plate. The top plate and bottom plate are respectively located on the upper and lower sides of the side plate, and extend away from the side plate. A second mounting part 21 is disposed on the top plate. Optionally, the second mounting part 21 includes a strip-shaped hole. The insertion section 122 of the insulation rack 1 is inserted into the strip-shaped hole on the top plate, and the bent section 121 of the insulation rack 1 abuts against the upper surface of the top plate. An abutment plate 14 abuts against the side plate. The side of the top plate away from the side plate is provided with a downwardly folded flange. The mounting bracket 2 also includes multiple connecting plates. The connecting plates are fixed to the flange and the bottom plate. The connecting plates are provided with connecting holes. Fasteners pass through the connecting holes and the rear side wall of the furnace body 3 to detachably install the mounting bracket 2 onto the furnace body 3.

[0049] like Figure 3 As shown, the bent section 121, the top plate, and the mounting plate 16 are parallel, which facilitates the bending section 121 abutting against the top plate or the mounting plate 16. The top plate can be set horizontally or inclined downward toward the frame 11.

[0050] like Figure 4 As shown, the heat preservation rack 1 is connected to the mounting bracket 2 by the hook part 12. When the heat preservation rack 1 is not in use, it can be flipped upward, which can increase the operating space above the grilling area and make it convenient for users to grill.

[0051] In other embodiments, the mounting part can also be provided on the front side wall of the support plate 13, and the corresponding connecting part is provided on the rear side wall of the support plate 13. The connecting part is provided with a slot with the opening facing downward. When the front and rear heat preservation racks 1 are assembled, the slot is inserted into the mounting part from top to bottom.

[0052] In other embodiments, the front and rear insulation frames 1 can also be detachably connected by fastening.

[0053] According to an embodiment of the present invention, another aspect, a baking oven is also provided, such as... Figure 6As shown, the oven includes an oven body 3 and a heat preservation rack 1 assembly as described in the above embodiment.

[0054] In this oven structure, the warming rack 1 assembly is mounted on the oven body 3 via mounting bracket 2. Multiple warming racks 1 can be sequentially assembled along the front-to-back direction of the oven body 3, depending on usage requirements. Along this direction, some warming racks 1 can extend towards the front of the oven body 3, reaching above the central area. This area has high residual heat from the main burner, effectively utilizing this heat to keep the food on the warming rack 1 warm, improving heat utilization and heat retention, ensuring the taste and texture of the grilled food, and enhancing the user experience. Furthermore, some warming racks 1 extend to the central area of ​​the oven body 3. Food placed on these racks above the central area can be grilled or smoked over a low flame using the main burner, meeting the user's grilling needs for different types of food. Alternatively, the warming rack 1 can be positioned on one side of the oven body 3's length, allowing users to grill from the other side, effectively preventing the rack from obstructing operation and improving the convenience of grilling.

[0055] like Figure 5 As shown, the oven also includes a grill rack and an infrared burner 4. The main burner is located inside the oven body 3, the grill rack is located above the main burner, and the infrared burner 4 is located on the rear wall of the oven body 3. Along the height of the oven body 3, the infrared burner 4 is positioned between the heat preservation rack 1 and the grill rack. Compared to ovens in related technologies, this oven structure adds an infrared burner 3 to the rear wall of the oven body 3. In the vertical direction of the oven body 3, the infrared burner 3 is positioned closer to the heat preservation rack 1 than the main oven body 3. When it is necessary to keep food warm, the infrared burner 3 can be turned on, and the heat generated by the electric heating of the infrared burner 3 can be used to keep the food warm, which can improve the heat preservation effect of the food and reduce the fuel consumption of the main oven body 3. The oven can also simultaneously utilize the residual heat of the main oven body 3 and the infrared burner 3 for heat preservation, which can effectively improve the heat preservation effect of the food.

[0056] The oven also includes a lid, which can be placed on the oven to extend the time food needs to be kept warm.

[0057] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0058] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
