DETAILED DESCRIPTION

[0035] The following examples are used to illustrate the present application, but the present application is not limited to these examples. Modifications or equivalent replacements to the specific embodiments of the present application or to some of the technical features without departing from the spirit of the present application should be covered in the technical solution range claimed by the present application.

[0036] Example 1

[0037] Reference Figures 1-5 The present embodiment provides a baking tray device 14, which includes a base 141 and an upper cover 142. The base 141 is provided with a containing area 1411 with an upward opening. The upper cover 142 is detachably provided on the top of the base 141. The upper cover 142 and the containing area 1411 are combined to form a closed cooking space 143. A gas outlet 144 is provided at a position corresponding to the mounting hole 1521 of the upper cover 142 and is in communication with the cooking space 143, or a gas outlet 144 is formed between the upper cover 142 and the base 141 and is in communication with the cooking space 143. In the present embodiment, the containing area 1411 has a flared structure with a small lower end and a large upper end. The baking tray device 14 is configured to be placed in the cooking cavity 121 of the gas oven 1, and the free end of the gas outlet 144 is configured to be in communication with the smoke blocking cavity 122 in the gas oven 1.

[0038] Reference Figures 1-2 When the above-mentioned baking tray device 14 is placed in the cooking cavity 121 of the gas oven 1, the gas outlet 144 of the baking tray device 14 is in communication with the smoke blocking cavity 122 of the gas oven 1, so that the food in the cooking space 143 is separated from the cooking cavity 121 of the gas oven 1. On the one hand, it avoids the direct contact between the combustion fumes generated by the operation of the gas oven 1 and the food in the baking tray device 14, reduces the generation of harmful substances in the food, and on the other hand, it avoids the oil splashed during the cooking process of the food from falling into the cooking cavity 121 of the gas oven 1, prevents the cooking cavity 121 from being contaminated by the oil, and makes the cooking cavity 121 easier to clean.

[0039] Reference Figures 3-5 Further, a flow guide portion (not shown in the figure) is provided at the top of the upper cover 141 corresponding to the position of the containing area 1411. The flow guide portion is used to guide the fluid at the top of the upper cover 141 to drip to a designated position at the bottom of the containing area 1411, so as to avoid the pollution of the food or the poor taste of the food by the fluid.

[0040] Reference Figures 2-5Specifically, the free end of the air outlet 144 protrudes outward beyond the outer edge of the base 141 and the upper cover 142, so as to facilitate the free end of the air outlet 144 to communicate with the smoke blocking cavity 122 in the gas oven 1. In addition, the air outlet 144 is trapezoidal with a large lower end and a small upper end, and the caliber of the air outlet 144 gradually increases from the cooking space 143 outward, so as to facilitate the cooking oil fume in the cooking space 143 to be quickly discharged to the smoke blocking cavity 122 of the gas oven 1 through the air outlet 144.

[0041] Reference Figure 4 Specifically, the upper cover 142 is provided with an upper concave cavity 1421 extending upward and opening downward, which surrounds the cooking space 143 with the containing area 1411, so that the height and volume of the cooking space 143 are larger, suitable for accommodating food with larger volume, and at the same time, the overall strength of the upper cover is strengthened. In this embodiment, the upper concave cavity 1421 is a necked structure with a large lower end and a small upper end, and the containing area 1411 is an expanded structure with a small lower end and a large upper end, so that the cooking space 143 formed by the two is arranged with a large middle and small ends.

[0042] Reference Figures 3-5 A protruding part (not shown in the figure) extending upward and used for supporting food is provided at the bottom of the containing area 1411, so as to facilitate reducing the contact area of the food with the base 141 and reducing the risk of the food being roasted; and / or a liquid storage groove (not shown in the figure) opening upward is recessed at the outside of the bottom of the containing area 1411, so as to inject clean water into the liquid storage groove before cooking, so as to keep the food moist and avoid roasting, and in addition, the liquid storage groove can be used to collect oil during cooking.

[0043] Specifically, the protruding part can be a large boss formed by local upward stamping of the bottom of the containing area 1411 (i.e. the bottom of the base 141), so as to facilitate rapid molding; or the protruding part includes at least one row of protruding groups, the protruding group includes a plurality of small bosses 1412 arranged side by side and spaced apart in the left-right or front-rear direction, a channel for passing fluid such as oil is formed between adjacent two small bosses 1412, and the small boss 1412 is formed by local upward stamping of the bottom of the containing area 1411 (i.e. the bottom of the base 141), so as to facilitate rapid molding and strengthen the strength of the base 141. The small boss 1412 is trapezoidal, conical or hemispherical with a large lower end and a small upper end, or rectangular.

[0044] Specifically, the liquid storage groove can be an annular groove arranged at the periphery of the protruding portion, or the liquid storage groove can include two strip-shaped grooves 1413 arranged oppositely, and the two strip-shaped grooves 1413 are arranged at the left and right sides or the front and back sides of the containing area respectively, and the two strip-shaped grooves 1413 are located at the opposite two outer sides of the protruding portion. The annular groove or the strip-shaped groove 1413 is formed by locally punching down the bottom of the containing area 1411 (i.e., the bottom of the base 141) in one piece, so as to facilitate rapid forming and strengthen the strength of the base 141. In this embodiment, the lower end of the liquid storage groove protrudes downward from the bottom surface of the base 141, i.e., the lower end of the annular groove or the strip-shaped groove 1413 extends downward below the bottom surface of the base 141, so that the liquid storage groove (i.e., the annular groove or the strip-shaped groove 1413) can serve as a supporting leg to reliably support the baking tray device 14, and the placing stability of the baking tray device is improved.

[0045] Reference Figures 3-5 A lower convex edge 1414 extending outward and located at the periphery of the containing area 1411 is integrally formed at the top periphery of the base 141, and an upper convex edge 1422 extending outward is integrally formed at the position corresponding to the lower convex edge 1414 of the upper cover 142, and the upper convex edge abuts against the lower convex edge to form a face-to-face contact to improve the air tightness therebetween, which not only prevents the combustion flue gas from entering the cooking space through the gap between the upper convex edge and the lower convex edge and contacting the food, but also prevents the cooking flue gas from flowing out through the gap between the upper convex edge and the lower convex edge to pollute the cooking cavity 121 or the combustion device.

[0046] Reference Figures 3-5 The flow guide portion includes a dome 1424 integrally punched upward from the top of the upper cover 142, and the orthographic projection of the dome 1424 covers the entire protruding portion, so as to increase the cooking space 143, and the oil drops or water drops at the top of the dome 1424 can smoothly drip along the oil path to the designated position at the bottom of the base 141, which is the area at the bottom of the containing area 1411 outside the protruding portion, so as to avoid contaminating the food or affecting the taste of the food. In this embodiment, the top of the dome 1424 gradually decreases from front to back along the length direction thereof, and the low end of the top of the dome 1424 is arranged close to the air outlet, so that the flue gas and water vapor generated during the cooking process drip downward along the lowest part of the top of the dome 1424 to the area at the bottom of the containing area 1411 behind the protruding portion, forming a path for the condensed water vapor, and the condensed water drops formed at the top of the upper cover 142 are prevented from dripping onto the food being cooked, which affects the taste of the food.

[0047] In other embodiments, a plurality of guide grooves 1425 can be used instead of the dome 1424, the plurality of guide grooves 1425 being arranged side by side and spaced apart on the top of the upper cover 142 and communicating with the cooking space 143, the guide grooves 1425 being formed by local integration of the top of the upper cover 142 and being upwardly punched and formed, the front and rear ends of the guide grooves 1425 protruding or flush with the front and rear ends of the protruding portion, respectively, the guide grooves 1425 being used to guide the fluid to drip to a designated position at the bottom of the holding area 1411, that is, the guide grooves 1425 are used to guide water droplets or oil droplets to the area at the bottom of the holding area 1411 outside the protruding portion, so that the falling point of the water droplets or oil droplets is located in the area outside the protruding portion. Since the protruding portion of the base 141 is used to place food, such a design can avoid water droplets or oil droplets from falling onto the food.

Therefore, when the flange hole 1415 and the corresponding positioning hole 1423 cooperate, not only can the upper cover be quickly positioned and fixed on the base to effectively prevent the risk of falling during installation, but also can quickly raise the heat, thereby better realizing the uniformity of the temperature field in the cooking cavity 121.

[0058] Of course, the positions of the positioning hole and the flange hole can also be exchanged, that is, the positioning hole is formed on the lower convex edge 1414 of the base 141, and the flange hole is arranged on the upper convex edge 1422 of the upper cover 142 and extends downward, so that the flange hole of the upper convex edge can extend downward into the positioning hole of the lower convex edge.

[0059] Embodiment 2

[0060] Reference Figures 10-12 The difference between the present embodiment and Embodiments 1 or 2 is that the flow guide part includes a dome 1424 and a plurality of flow guide grooves 1425, the dome 1424 is formed by locally punching and forming upward from the top of the upper cover 142, and is used to guide the fluid to drip to the outer periphery of the bottom of the containing area 1411. In the present embodiment, the orthographic projection of the dome 1424 covers the entire convex part, so as to increase the cooking space 143, and make the oil drops or water drops on the top of the dome 1424 smoothly drip along the oil path to the set position of the base 141, that is, to the area on the bottom of the containing area 1411 outside the convex part, so as to avoid contaminating the food or making the food taste bad.

[0061] The plurality of flow guide grooves 1425 are arranged side by side and spaced apart on the top surface of the dome 1424 and communicate with the cooking space 143, and the flow guide grooves 1425 are formed by locally punching and forming upward from the top of the dome 1424. The flow guide grooves 1425 are used to guide the fluid to drip to the set position of the bottom of the containing area 1411, that is, to guide the water drops or oil drops to the area on the bottom of the containing area 1411 outside the convex part, so that the falling point of the water drops or oil drops is located in the area outside the convex part. Since the convex part of the base 141 is used to place food, such design can avoid the water drops or oil drops from dripping onto the food.

[0062] In the embodiment, the guide groove 1425 gradually decreases from front to back along its length direction, and the low end of the guide groove is arranged close to the air outlet, so that the smoke and water vapor condensate generated in the cooking process drop along the lowest part of the guide groove 1425 to the area at the bottom of the holding area 1411 behind the protruding part, forming a condensate path, avoiding the condensate drops formed on the top of the upper cover 142 from falling on the food being cooked, resulting in poor taste of the food. In addition, the size of the guide groove 1425 gradually decreases along its length direction, so as to better guide the condensate or condensate oil.

[0063] The above only describes some embodiments of the present application. For those skilled in the art, without departing from the inventive concept of the present application, a number of modifications and improvements can be made, which are all within the scope of protection of the present application.
