Description

Technical Field

[0001] The utility model relates to the technical field of cooking appliances, and particularly relates to a large anti-deformation cast iron baking plate and a baking oven. Background Art

[0002] A barbecue oven includes a furnace base provided with a combustion heating structure and a baking plate; for example, a barbecue oven disclosed in Patent No. CN210169808U. A large flat baking plate is mostly used for cooking such as teppanyaki. The baking plate is usually a box-shaped structure with a large area and an open top, and is usually made of cast iron or stainless steel. However, due to the large area span of the baking plate and the fact that the heat generation area of the combustion structure is usually close to the middle of the baking plate, especially for gas barbecue ovens, the heat distribution of gas combustion is uneven. When the baking plate is unevenly heated, the middle of the baking plate is prone to concave deformation. Irregular deformation is also likely to occur when low-temperature ingredients are used or when the high-temperature baking plate is rinsed, resulting in difficult discharge of accumulated cooking oil. In the prior art, in addition to increasing the plate thickness to increase the strength of the baking plate and improve the anti-deformation ability, the following means are also used to reinforce the strength of the baking plate:

[0003] For a stainless steel baking plate, it is usually reinforced by welding several U-shaped, V-shaped and other stainless steel pipes under the baking plate; however, the welding points between the main body of the baking plate and the steel pipes are easily exposed above the baking plate, and usually additional polishing and grinding processes are required. Poor surface treatment of some workpieces can also directly affect the appearance;

[0004] For a cast iron baking plate, in addition to increasing the plate thickness to 6-8 mm; usually a grid-shaped reinforcing rib structure is integrally cast under the baking plate.

[0005] The above methods for improving the anti-deformation of the baking plate, whether increasing the plate thickness or additionally setting a reinforcing structure, will increase the material or process, and will significantly increase the production cost of the baking plate, and the competitiveness of the product is weak. Therefore, further improvement is needed. Summary of the Utility Model

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a large anti-deformation cast iron baking plate and a baking oven.

[0034] In the present utility model, the baking plate is integrally formed by casting, and the shape of the baking plate body can be adjusted according to the design state. The thickness of the central cooking area 11 of the main baking plate 10 is greater than the thickness of the outer cooking area 12; the main baking plate 10 is arranged in an arched structure. In the present utility model, the main baking plate 10 is arranged in an arched structure with a gradually decreasing thickness. On the one hand, the central area with a larger thickness itself has a strong anti-deformation ability, and the outer cooking area 12 is not easily deformed. By reducing the thickness, the material usage and the weight of the baking tray can be effectively reduced; moreover, the arched structure of the central cooking area 11 causes the heat stress to spread outwards towards the outer edge, and it is not easy to generate a state of strong local stress, providing an upward pre-deformed form, which can effectively prevent the deformation of the middle part of the baking plate from sagging and has a strong anti-deformation ability. In the case of a relatively thin plate thickness, the material usage and processing procedures are effectively reduced, the production cost is significantly reduced, and the product competitiveness is strong.

[0035] In this embodiment, according to the thickness change of the plate type, there are two types of arched structures; one is that the upper surface of the main baking plate 10 is arranged in an arched structure and the lower surface is arranged in a flat structure; the other is that both the upper surface and the lower surface of the main baking plate 10 are arranged in an arched structure.

[0036] In this embodiment, the shape of the cross-sectional thickness change generally has the following several types: The cross-sectional shape of the central cooking area 11 of the baking plate main board 10 facing the outer edge cooking area 12 is one shape or a combination of shapes such as a stepped shape, an arc-transition shape, and a linear-transition shape. Specifically as follows:

[0037] In this embodiment, as shown in the appendix Figure 4 As shown, the cross-sectional shape of the central cooking area 11 of the baking plate main board 10 facing the outer edge cooking area 12 is an arch-shaped structure with an arc transition. In this structure, the whole baking plate arches in the middle and gradually narrows towards the outer periphery. It can effectively transfer the stress of thermal deformation, has strong anti-deformation ability, and the surface is smooth and continuous, and the operation feeling of touching, cleaning, and cooking is good.

[0038] In some other embodiments, as shown in the appendix Figure 5 As shown, the cross-sectional shape of the central cooking area 11 of the baking plate main board 10 facing the outer edge cooking area 12 is an arch-shaped structure in the shape of an eight-character with a linear transition.

[0039] In some other embodiments, as shown in the appendix Figure 6 As shown, the cross-sectional shape of the central cooking area of the baking plate main board 10 facing the outer edge cooking area 12 is an arch-shaped structure with multiple flat steps and gradually decreasing thickness.

[0040] Of course, in addition to the cross-sectional shapes shown in appendix Figure 4 to appendix Figure 6 As shown, the arched baking plate body can also be composed of a combination of stepped shapes, arc-transition shapes, and linear-transition shapes.

[0041] Please refer to Figure 3 and Figure 4 , in this embodiment, the thickness of the cross-section of the central cooking area 11 of the baking plate main board 10 gradually decreases towards the outer edge cooking area 12. It can effectively transfer the stress of thermal deformation, has strong anti-deformation ability, and the surface is smooth and continuous. Moreover, the arched structure with the middle arched also facilitates the flow of grease towards the periphery for drainage and collection.

[0042] In this embodiment, the cross-sectional shape of the central cooking area 11 of the baking plate main board 10 facing the outer edge cooking area 12 is an arched structure with an arc transition, and the thickness of the cross-section gradually decreases.

[0043] In this embodiment, through multiple tests and verifications, the thickness difference between the maximum thickness of the central cooking area 11 and the minimum thickness of the outer edge cooking area 12 is within the range of 1 - 3 mm. According to the overall area span of the baking plate, for example, the thickness difference is designed to be 1 mm, 1.5 mm, 2 mm, 2.5 mm, or 3 mm, etc.

[0044] Further, according to the load-bearing requirements, after multiple tests and verifications, the maximum thickness of the central cooking area 11 is within the range of 4 - 8 mm; the minimum thickness of the outer-edge cooking area 12 is within the range of 3 - 6 mm. For example, the maximum value of the thickness of the central area can be set to 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 7 mm or 8 mm; the minimum value of the thickness of the outer-edge cooking area 12 can be set to 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm or 6 mm, etc.

[0045] In this embodiment, in order to facilitate the discharge and collection of grease in the baking plate, the main baking plate 10 is provided with an oil guide channel 13 and an oil drain port 14.

[0046] In this embodiment, support feet 15 are provided below the main baking plate 10, and the support feet 15 can make the baking plate be placed above the furnace base.

[0047] Further, the length of the support feet 15 near the oil drain port 14 is shorter than that of the other support feet 15, so that after the main baking plate 10 is placed, the whole is inclined towards the oil drain port 14, and the oil stain can flow and be collected towards the oil drain port 14 better.

[0048] In some embodiments, the baking plate ring wall 20 is arranged around the periphery of the baking plate body, which can facilitate the cooking operation of the baking plate body. Further, the cross-section of the baking plate ring wall 20 is arranged in a tower-shaped structure with the cross-section narrowing from bottom to top; this tower-shaped structure can reduce the material usage of the baking plate ring wall 20, and can better facilitate the mold demolding operation, and the feasibility of baking plate production is high.
