Description

Technical Field

[0001] This utility model relates to the field of oven technology, specifically to an oven rack that prevents the baking tray from deforming and falling off. Background Technology

[0002] In the oven baking field, apart from special categories such as commercial rack ovens and pizza ovens, mainstream household and commercial ovens such as open-top ovens and convection ovens all include racks as a standard component. The core value of racks lies in two main aspects: First, by adjusting the height of the racks within the oven cavity, they can adapt to the baking needs of foods of different heights, ensuring that the food is in the optimal heating zone for even baking; second, thanks to the multi-layer rack design, multiple trays of food can be baked simultaneously, significantly improving the oven's efficiency and meeting the needs of batch baking scenarios.

[0003] However, all existing oven racks suffer from a fundamental flaw: each rack uses a single metal rod support structure, relying solely on a single metal rod at the bottom of the baking tray on either side for support. During high-temperature baking, the baking tray is subject to drastic temperature changes, inevitably leading to thermal expansion and contraction, resulting in deformation and warping. This not only directly disrupts the evenness of heating the food, resulting in poor taste and appearance of the baked goods, but more seriously, a deformed baking tray may detach from the support of the single metal rod, posing a safety hazard and the risk of it falling over. Utility Model Content

[0004] The purpose of this invention is to provide an oven rack that prevents the baking tray from deforming and falling off, thereby solving the problem that current oven racks are unable to maintain stable support for the baking tray during high-temperature baking.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oven rack for preventing baking tray deformation and falling off, used to support the baking tray. The baking tray has lugs on both sides, and the side racks are fixed in pairs to both sides of the oven cavity. Each side rack includes a frame fixedly connected to both sides of the oven cavity wall and multiple support parts fixed vertically to the inner side of the frame. Each support part includes a lower support member with its front and rear ends fixed to the inner side of the frame, and an upper support member with its front and rear ends fixed to the inner side of the frame and parallel to the lower support member. The front end of the upper support member has an outwardly folded portion forming a clearance structure.

[0006] Preferably, the frame is fixed with a fixing plate on the upper and lower sides of the middle of the front and rear parts, and the fixing plate is fitted with a fixing screw that matches the threaded connection of the inner cavity side wall of the oven.

[0007] Preferably, the inner sidewall of the fixing plate is provided with a circular groove in the middle, and the center of the circular groove is provided with a through hole that matches the movable sleeve of the fixing screw.

[0008] Preferably, the net distance between the upper support and the lower support is 1-2 mm greater than the thickness of the lug.

[0009] Preferably, the longitudinal length of the outward fold is 2 to 5 cm.

[0010] Preferably, the lower support and the upper support are either a rod or a plate.

[0011] Preferably, the lower support and the upper support are made of stainless steel or electroplated iron.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The oven rack of this utility model that prevents the baking tray from deforming and falling off is designed to prevent the baking tray from falling off due to deformation by adding an upper support component to forcibly limit the baking tray lugs, thereby improving the safety and reliability of the oven.

[0013] 2. The oven rack of this utility model that prevents the baking tray from deforming and falling off has a simple overall structure and is easy to place the tray, thus making it easy to promote and apply. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-2 This utility model provides a technical solution: an oven rack to prevent the baking tray from deforming and falling off, used to support the baking tray 1, with lugs 1.1 on both sides of the baking tray 1.

[0018] Side frames 2 are fixed in pairs to both sides of the oven cavity. Each side frame 2 includes a frame 2.1 fixedly connected to the side walls of the oven cavity and multiple support parts 2.3 vertically fixed to the inner side of the frame 2.1. Each support part 2.3 includes a lower support member 2.3.1 with its front and rear ends fixed to the inner side of the frame 2.1, and an upper support member 2.3.2 with its front and rear ends fixed to the inner side of the frame 2.1 and parallel to the lower support member 2.3.1. The front end of the upper support member 2.3.2 has an outwardly folded portion 2.3.2.1 forming a clearance structure. The net distance between the upper support member 2.3.2 and the lower support member 2.3.1 is 1-2 mm larger than the thickness of the lug 1.1. The longitudinal length of the outwardly folded portion 2.3.2.1 is 2-5 cm. The lower support member 2.3.1 and the upper support member 2.3.2 are either rods or plates. The lower support 2.3.1 and the upper support 2.3.2 are made of either stainless steel or electroplated iron. The inward protrusion of the upper support 2.3.2 and the lower support 2.3.1 relative to the frame 2.1 is matched with the width of the lug 1.1 to prevent the baking pan 1 from sliding excessively to the sides.

[0019] In summary, during use, the outward fold 2.3.2.1 at the front end of the upper support 2.3.2 forms a clearance structure. Thus, when placing the baking tray 1, the rear ends of the two side lugs 1.1 of the baking tray 1 are placed on the lower support 2.3.1 from the clearance structure, and then the baking tray 1 is pushed backward, which can quickly complete the placement of the baking tray 1 and solve the problem of difficult alignment when placing the baking tray 1.

[0020] The spacing between the upper support 2.3.2 and the lower support 2.3.1 allows the lug 1.1 to move in and out smoothly. This not only ensures that the upper support 2.3.2 limits the lug 1.1, but also meets the need for convenient loading and unloading of the baking tray 1.

[0021] The lugs 1.1 on both sides of the baking tray 1 are supported and limited by the upper support 2.3.2 and the lower support 2.3.1 simultaneously. So when the baking tray 1 is deformed by thermal expansion and contraction during high-temperature baking, the lugs 1.1 are limited by the limiting effect of the upper support 2.3.2 and the baking tray 1 will not fall off.

[0022] In addition, fixing plates 2.2 are fixed to the upper and lower sides of the front and rear middle parts of the frame 2.1, respectively. Fixing plates 2.2 are fitted with fixing screws 3 that are threaded into the inner wall of the oven cavity. A circular groove 2.2.1 is provided in the middle of the inner wall of the fixing plate 2.2, and a through hole 2.2.2 in the middle of the circular groove 2.2.1 is provided to movably fit the fixing screws 3. This allows for flexible adjustment of the overall installation height of the oven racks according to the oven cavity dimensions and the placement of the upper and lower electric heating elements. Appropriately positioned threaded holes are provided on both sides of the oven cavity. Then, the side racks 2 can be fixed to the oven cavity side walls using the fixing screws 3, with the ends of the fixing screws 3 accommodated within the circular grooves 2.2.1 to ensure overall flatness and aesthetics.
