[0003] Traditional oven racks are typically fixed or detachable, installed on the left and right sides of the oven cavity to support baking trays, racks, etc. However, both types present cleaning challenges. Fixed racks are permanently connected to the cavity, making thorough cleaning impossible and leaving grease and grime difficult to remove. Detachable racks, while removable, have numerous parts, making disassembly and reassembly cumbersome and inconvenient for users. Furthermore, frequent disassembly can damage or lose parts, increasing maintenance costs. Therefore, designing an easy-to-clean rack structure has become a pressing issue in the field of oven technology. Utility Model Content

[0004] In view of the technical problems of the inner pot of cooking equipment being difficult to clean and the rack being inconvenient to install and disassemble in the existing technology, this utility model provides a shelf structure. The shelf structure can be removed as a whole from the inner cavity, which is convenient for cleaning the inner cavity. At the same time, through the quick-release connecting component, the shelf structure can be quickly locked and disassembled, which is convenient for cleaning the shelf.

[0045] Reference Figures 1-6 Some embodiments of this application provide a shelf structure for cooking equipment.

[0046] like Figure 1 and Figure 2 As shown, the shelving structure includes an upper shelf 100, a lower shelf 200, two side shelves 300, and multiple quick-release connecting components 400.

[0047] The upper frame 100 and the lower frame 200 serve as the top and bottom supports of the frame, respectively. The left and right side frames 300 are connected to the upper frame 100 and the lower frame 200 through multiple quick-release connecting components 400 to form a stable frame structure.

[0048] The left and right side racks 300 include two uprights 310 and a support crossbar 320 connecting the uprights 310. The uprights 310 serve to support and connect, and the support crossbar 320 is used to support cooking utensils such as baking trays, grill racks or steaming trays.

[0049] Quick-release connection components 400 are respectively located at the upper and lower ends of the column 310 to enable quick locking and separation of the side frame 300 from the upper frame 100 and the lower frame 200.

[0050] The aforementioned shelf structure allows for complete insertion and removal from the cooking equipment's interior cavity. The interior sidewalls of the cooking equipment require no fixing structure, remaining smooth and flat, greatly facilitating user cleaning. Simultaneously, the shelf structure utilizes quick-release connecting components 400 for rapid locking and disassembly, allowing users to easily connect or detach the left and right side shelves 300 from the upper shelf 100 and lower shelf 200, significantly simplifying operation and improving ease of use. Furthermore, the shelf structure can be completely disassembled into four independent parts: the upper shelf 100, the lower shelf 200, and the left and right side shelves 300, facilitating thorough cleaning and effectively avoiding the cleaning difficulties associated with traditional fixed racks.

[0051] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the quick-release connection assembly 400 includes a pivot 410, a locking element 420, and an elastic element 430.

[0052] The pivot 410 is fixed to the upper shelf 100 or the lower shelf 200, serving as the pivot point for the locking element 420.

[0053] like Figure 5 The locking element 420 has a cylindrical structure, with one end hinged to the upper shelf 100 or the lower shelf 200 via a pivot 410, and the other end being an open end. The side wall of the locking element 420 has a continuous groove consisting of a vertical sliding groove 421 and a locking groove 422.

[0054] The elastic element 430 is disposed in the inner cavity of the locking element 420 to provide a restoring force.

[0055] The end of the column 310 is provided with a radially protruding positioning pin 311. When the locking member 420 is inserted, the positioning pin 311 moves down along the vertical slide groove 421 and compresses the elastic member 430. Rotating the locking member 420 causes the positioning pin 311 to be engaged in the locking groove 422. The restoring force of the elastic member 430 presses the positioning pin 311 tightly against the end of the locking groove 422 to achieve locking.

[0056] During disassembly, rotating the locking element 420 compresses the elastic element 430, causing the positioning pin 311 to slide out from the locking groove 422 and the vertical slide groove 421 in the locking element 420, thereby disassembling the upper and lower shelves 200 and the left and right side shelves 300. The shelf structure can be disassembled into four parts: the two left and right side shelves 300, the upper shelf 100, and the lower shelf 200.

[0057] The quick-release connection assembly 400 of this embodiment has a simple structure and is easy to operate. The side frame 300 can be quickly locked and disengaged by rotating the locking member 420, a simple operation requiring no additional tools. Simultaneously, the restoring force of the elastic member 430 ensures that the positioning pin 311 is always pressed against the end of the locking groove 422, guaranteeing the reliability of the connection and preventing accidental loosening. Furthermore, the quick-release connection assembly 400 has a compact design, occupies little space, and does not affect the overall aesthetics and functionality of the side frame 300.

[0058] In some embodiments of this application, further, such as Figure 5 As shown, the locking groove 422 includes a connecting section 4221 connected to the end of the vertical slide groove 421, and a locking section 4222 connected to the connecting section 4221 and vertically formed. The vertical design of the locking section 4222 ensures that the positioning pin 311 will not disengage due to external force after locking, thus improving the reliability of locking.

[0059] Preferably, the connecting section 4221 is arc-shaped to guide the positioning pin 311 smoothly from the vertical groove 421 to the locking section 4222. The arc-shaped connecting section 4221 reduces the friction of the positioning pin 311 during rotation, making the operation smoother.

[0060] In some other embodiments, the connecting segment 4221 may also be a straight line segment. Alternatively, the locking segment 4222 may be entirely a straight line segment or an arc segment.

[0061] In some embodiments of this application, the elastic element 430 is a spring disposed in the inner cavity of the locking element 420, for providing compressive force when the locating pin 311 is inserted, and for providing a restoring force after the locking element 420 is rotated.

[0062] In some embodiments of this application, the locking member 420 has a through hole at its bottom end, and the rotating shaft 410 is a separate component, including a fixing post 411 and a nut 412. One end of the fixing post 411 is fixedly connected to the upper shelf 100 or the lower shelf 200, and the other end passes through the through hole and is threadedly connected to the nut 412. Through the threaded connection, the user can easily install or remove the locking member 420, facilitating maintenance and replacement.

[0063] In some other embodiments, the pivot 410 may also be a one-piece component with a T-shaped cross-section, which is fixed to the lower shelf 200 by means of bottom thread or welding.

[0064] In some embodiments of this application, multiple support crossbars 320 are provided to form a multi-layer support structure, and the spacing between each layer of support crossbars 320 can be adjusted according to user needs. The multi-layer support structure can be flexibly adjusted according to cooking requirements to meet the baking or steaming needs of different foods. At the same time, it has high space utilization, making full use of the vertical space inside the oven cavity and improving cooking efficiency.

[0065] To facilitate easy pushing and pulling of the side frame 300, the shelf structure is also equipped with handles 500.

[0066] In some embodiments, a handle 500 is provided on the upper shelf 100. The handle 500 is located on the upper part of the entire shelf structure and is suitable for drawer-type cooking appliances. After the drawer is pulled out, the entire shelf structure can be lifted out from the top.

[0067] In other embodiments, such as Figure 6 As shown, handles 500 are provided on the front of the left and right side shelves 300 respectively. The handles 500 are located at the front of the entire shelf structure and are suitable for cooking appliances with a flip-down door. When the door is opened, the entire shelf structure can be pulled out or pushed in from the inner pot.

[0068] In some embodiments of this application, the bottom of the lower shelf 200 is provided with sliding wheels (not shown) to facilitate pushing or pulling the side shelf 300 into or out of the inner cavity. A slide rail can be provided in the inner cavity to cooperate with the sliding wheels. The sliding wheels make the movement of the side shelf 300 easier, especially significantly reducing the difficulty of operation when carrying heavy objects.

[0069] This invention also includes a cooking device with a shelf structure as described above in its internal cavity. This cooking device can be a steam oven, oven, or other similar cooking appliance.

[0070] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
