Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a baking tray device and its gas oven. Background Technology

[0002] Existing electric ovens or electric steam ovens all use electricity to heat food, resulting in complex systems and numerous components, thus increasing costs. Since the heating element is typically designed inside the cavity, grease and grime accumulate on the surface over time, making it difficult to clean. Furthermore, the heating element suffers from limitations in overall machine power and low efficiency, leading to relatively slow cooking speeds in actual operation.

[0003] In foreign kitchens, some use gas ovens, such as traditional Japanese ovens, where food is placed inside and heated directly by the smoke from burning gas. Existing baking pans are usually open at the top, allowing the smoke from the combustion process to directly contact the food. Because incomplete combustion can occur with gas, some smoke odor may remain on the food, potentially posing a health risk to the user. Summary of the Invention

Detailed Implementation

[0031] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0032] Example 1

[0033] refer to Figure 1-5 This embodiment provides a baking tray device 14, which includes a base 141 and a top cover 142. The base 141 has an upward-opening holding area 1411, and the top cover 142 is detachably mounted on the top of the base 141. The top cover 142 and the holding area 1411 enclose a sealed cooking space 143. An air vent 144 communicating with the cooking space 143 is provided at the position corresponding to the mounting opening 1521 on the top cover 142, or an air vent 144 communicating with the cooking space 143 is formed between the top cover 142 and the base 141. In this embodiment, the holding area 1411 has an flared structure with a smaller lower end and a larger upper end. The baking tray device 14 is configured to be placed in the cooking cavity 121 of a gas oven 1, and the free end of the air vent 144 is configured to communicate with the smoke-proof cavity 122 in the gas oven 1.

[0034] refer to Figure 1-2When the baking tray device 14 is placed inside the cooking cavity 121 of the gas oven 1, the air outlet 144 of the baking tray device 14 is connected to the smoke baffle 122 of the gas oven 1, thereby separating the food in the cooking space 143 from the cooking cavity 121 of the gas oven 1. This prevents the combustion fumes generated by the gas oven 1 from directly contacting the food in the baking tray device 14, reducing the generation of harmful substances in the food. It also prevents the grease generated during the cooking process from splashing into the cooking cavity 121 of the gas oven 1, preventing the cooking cavity 121 from being contaminated by grease and making the cooking cavity 121 easier to clean.

[0035] refer to Figure 2-5 Specifically, the free end of the air outlet 144 protrudes outward from the outer edge of the base 141 and the top cover 142, thereby facilitating communication between the free end of the air outlet 144 and the smoke-blocking cavity 122 in the gas oven 1. Furthermore, the air outlet 144 is trapezoidal in shape, wider at the bottom and narrower at the top, and its diameter gradually increases outward from the cooking space 143, thereby facilitating the rapid discharge of cooking fumes from the cooking space 143 into the smoke-blocking cavity 122 of the gas oven 1 through the air outlet 144.

[0036] refer to Figure 5 Specifically, the upper cover 142 has an upwardly extending and downwardly opening concave cavity 1421. This concave cavity 1421, together with the holding area 1411, encloses the cooking space 143, thereby increasing the height and volume of the cooking space 143 to accommodate larger foods and also enhancing the overall strength of the upper cover. In this embodiment, the concave cavity 1421 has a constricted structure that is larger at the bottom and smaller at the top, while the holding area 1411 has an flared structure that is smaller at the bottom and larger at the top, so that the cooking space 143 formed by the two is larger in the middle and lower at both ends.

[0037] refer to Figure 3-5 The bottom of the holding area 1411 has an upwardly extending protrusion (not shown in the figure) for supporting food, which helps to reduce the contact area between the food and the base 141 and reduce the risk of the food being burned; and / or the bottom outer side of the holding area 1411 has an upwardly opening liquid storage tank (not shown in the figure), which allows water to be injected into the liquid storage tank before cooking to keep the food moist and prevent it from burning. In addition, the liquid storage tank can be used to collect oil during the cooking process.

[0038] Specifically, the protrusion can be a large protrusion, which is formed by integrally stamping a portion of the bottom of the holding area 1411 (i.e., the bottom of the base 141) upwards to facilitate rapid forming; or the protrusion includes at least one row of protrusion groups, which includes multiple small protrusions 1412 arranged side by side at intervals along the left-right or front-back direction. A channel for fluids such as grease to pass through is formed between two adjacent small protrusions 1412. The small protrusions 1412 are formed by integrally stamping a portion of the bottom of the holding area 1411 (i.e., the bottom of the base 141) upwards to facilitate rapid forming and to strengthen the base 141. The small protrusions 1412 can be any of the following shapes: trapezoidal, conical, or hemispherical, with a larger bottom and a smaller top; they can also be rectangular.

[0039] Specifically, the liquid storage tank can be an annular groove, located around the periphery of the protrusion; or the liquid storage tank includes two oppositely arranged strip grooves 1413, respectively located on the left and right or front and rear sides of the holding area, and respectively located on opposite outer sides of the protrusion. The annular groove or strip groove 1413 is formed by a partial, integral downward stamping of the bottom of the holding area 1411 (i.e., the bottom of the base 141), which facilitates rapid forming and strengthens the base 141. In this embodiment, the lower end of the liquid storage tank protrudes downward from the bottom surface of the base 141, that is, the lower end of the annular groove or strip groove 1413 extends downward to below the bottom surface of the base 141, so that the liquid storage tank (i.e., the annular groove or strip groove 1413) can serve as a support foot, reliably supporting the baking tray device 14, which helps to improve the placement stability of the baking tray device.

[0040] refer to Figure 3-5 The base 141 has an integrally formed lower protruding edge 1414 extending outward and located around the holding area 1411. The upper cover 142 has an integrally formed upper protruding edge 1422 extending outward at the position corresponding to the lower protruding edge 1414. The upper protruding edge and the lower protruding edge abut against each other to form a surface-to-surface contact, which improves the airtightness between them. This prevents the combustion fumes from entering the cooking space between the upper and lower protruding edges and coming into contact with the food, and also prevents the cooking fumes from flowing out between the upper and lower protruding edges and contaminating the cooking cavity 121 or the combustion device.

[0041] refer to Figure 1-2This embodiment also provides a gas oven 1, which includes an outer shell assembly 11, an inner cavity assembly 12, a combustion device (not shown in the figure), and a baking tray device 14. The inner cavity assembly 12 is disposed inside the outer shell assembly 11, and a receiving cavity 114 is formed at the upper end of the outer shell assembly 11, located at the top of the inner cavity assembly 12 and opening upward. The receiving cavity 114 is configured to accommodate a cooktop module. Inside the inner cavity assembly 12, cooking chambers 121 and smoke-blocking chambers 122 are provided at intervals along the front-to-back direction to reduce interference between cooking fumes and combustion fumes. Support portions (not shown in the figure) are provided on the left and right side walls of the cooking chambers 121, which are configured to reliably support the baking tray device 14. A door assembly 17 is rotatably connected to the inner cavity assembly 12 for opening or closing the cooking chambers 121 of the inner cavity assembly 12. Between the smoke-blocking chamber 122 and the cooking chamber 121, exhaust ports 1522 and mounting ports are provided at intervals along the vertical direction. At least one exhaust port 123 communicating with the smoke-blocking chamber 122 is provided at the top or upper back of the inner liner assembly 12, so that cooking fumes in the smoke-blocking chamber 122 can be discharged upward in a timely manner through the exhaust port 123. The upper end of the cooking chamber 121 is connected to the upper end of the smoke-blocking chamber 122 or the exhaust port 123 through the exhaust port 1522, so that combustion fumes in the cooking chamber 121 can be discharged upward from the exhaust port 123.

[0042] The combustion device is installed on the inner liner assembly 12, and the smoke outlet of the combustion device is connected to the cooking cavity 121 to provide combustion smoke to the cooking cavity 121. The baking pan device 14 is detachably placed inside the cooking cavity 121, with its left and right ends respectively abutting against the support parts on the left and right sides of the cooking cavity 121. The baking pan device 14 has a sealed cooking space 143 and an air vent 144. The free end of the air vent 144 extends into the installation port 1521. The cooking space 143 is connected to the smoke-proof chamber 122 through the air vent 144, thereby separating the cooking space 143 from the cooking cavity 121. This prevents combustion fumes from coming into contact with the food inside the baking pan device 14, reducing the generation of harmful substances in the food. It also isolates the cooking cavity 121 and the combustion device from cooking fumes, preventing grease and oil droplets generated during food cooking from splashing into the cooking cavity 121 and the combustion device, avoiding the risk of fire caused by red flames, incomplete combustion, and grease accumulation. At the same time, it makes the cooking cavity 121 easier to clean.

[0043] refer to Figure 1-2 The outer shell assembly 11 is formed by the oven base plate 111, two oven side plates 112, and an oven back plate 113. The outer shell assembly 11 has a front opening and a top opening. The inner liner assembly 12 is installed inside the outer shell assembly 11 and covers the front opening of the outer shell assembly 11. The receiving cavity 114 is formed by the upper ends of the two oven side plates 112, the upper end of the oven back plate 113, and the top of the inner liner assembly 12.

[0044] refer to Figure 1-2 Furthermore, the gas oven also includes a smoke baffle 15. The inner cavity assembly 12 has a cavity 1202 with a forward opening. The smoke baffle 15 is disposed in the cavity 1202, with its upper end connected to the top of the inner cavity assembly 12 and its lower end connected to the rear bottom of the inner cavity assembly 12. The left and right ends of the smoke baffle 15 abut against or connect to the left and right side walls of the inner cavity assembly 12, respectively. The smoke baffle 15 divides the cavity 1202 into a cooking cavity 121 and a smoke baffle cavity 122 arranged at intervals. An installation port 1521 is provided in the middle of the smoke baffle 15, and an exhaust port 1522 is provided at the upper end of the smoke baffle 15 or between the smoke baffle 15 and the top of the inner cavity assembly 12. Without affecting the exhaust of the cooking cavity 121, the smoke baffle cavity 122 isolates the cooking cavity and the combustion device from oil or cooking fumes.

[0045] refer to Figure 1-2 The combustion device includes two oven burners 13, which are respectively disposed on the upper and lower sides of the inner liner assembly 12. The smoke outlet of the oven burners 13 is connected to the cooking cavity 121, thus forming a "bottom + top combined combustion system". Compared with existing electric ovens, it reduces complex components such as electric heating elements, power boards, and control boards, simplifies the heating system of oven module 1, has a simple structure, and uses gas as the heat source for food cooking. Gas has a high calorific value and faster heating speed, which is beneficial to improving cooking efficiency. In this embodiment, a lower combustion chamber 115 is formed between the oven bottom plate 111 and the bottom of the inner liner assembly 12. Multiple bottom smoke inlets 124 are opened at the bottom of the inner liner assembly 12, and the cooking cavity 121 and the lower combustion chamber 115 are connected through the multiple bottom smoke inlets 124. A top mounting port connected to the cooking cavity 121 is opened at the top of the inner liner assembly 12. One oven burner 13 is installed at the top mounting port and its smoke outlet is connected to the cooking cavity. The other is installed in the lower combustion chamber 115 and the combustion smoke generated by it flows into the cooking cavity through the bottom smoke inlet 124.

[0046] In this embodiment, a bottom air inlet 1111 is provided on the oven bottom plate 111 for air to pass through and connected to the lower combustion chamber 115, and a front air inlet 1201 is provided at the lower end of the inner liner front plate of the inner liner assembly 12 for air to pass through and connected to the lower combustion chamber 115. This allows for the supply of secondary air required for combustion to the oven burner 13 installed in the lower combustion chamber 115, ensuring more complete combustion.

[0047] refer to Figure 1-2Furthermore, the gas oven also includes a smoke exhaust device 16. The smoke exhaust device 16 is located at the top of the inner cavity assembly 12 corresponding to the smoke exhaust port 123. The two ends of the smoke exhaust device 16 are respectively connected to the smoke exhaust port 123 and the outside atmosphere, thereby facilitating the centralized discharge of fumes through the smoke exhaust device 16. Specifically, the smoke exhaust device 16 includes a smoke exhaust hood 161 and a fixed bracket 162. The smoke exhaust hood is fixedly installed on the top of the inner cavity assembly 12 via the fixed bracket, and the lower end of the smoke exhaust hood covers the periphery of the corresponding smoke exhaust port 123 and is connected to the corresponding smoke exhaust port 123.

[0048] Example 2

[0049] refer to Figure 6-9 The difference between this embodiment and embodiment 1 is that multiple ventilation holes are provided on the baking tray device 14 outside the cooking space 143 for airflow. When the baking tray device 14 divides the cooking space 121 of the gas oven 1 into upper and lower parts, the upper and lower parts can be connected through the ventilation holes, thereby better achieving the uniformity of the temperature field inside the cooking cavity 121.

[0050] Specifically, multiple positioning holes 1423 for airflow are provided on the upper convex edge 14 of the top cover 142. At the position corresponding to the positioning holes, the lower convex edge 1414 of the base 141 is provided with an upwardly extending flange hole 1415 for airflow. The flange hole 1415 forms a vent hole. The flange hole 1415 is inserted into the corresponding positioning hole 1423. With the flange hole 1415 and the corresponding positioning hole 1423 working together, the top cover can be quickly fixed on the base, effectively preventing the risk of slippage during installation. It can also help the heat rise quickly, and better achieve the uniformity of the temperature field inside the cooking cavity 121.

[0051] Of course, the positions of the positioning hole and the flange hole can also be interchanged. The positioning hole is made on the lower convex edge 1414 of the base 141, while the flange hole is set 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.

[0052] Example 3

[0053] refer to Figure 10-11The difference between this embodiment and Embodiments 1 or 2 lies in the specific structure of the smoke baffle 15. The smoke baffle 15 includes a lower guide section 151 and an upper smoke baffle section 152 fixedly connected and angled. The end of the lower guide section 151 away from the upper smoke baffle section 152 is connected to the rear bottom of the inner liner assembly 12, and the upper end of the upper smoke baffle section 152 is connected to the top of the inner liner assembly 12, thereby dividing the cavity of the inner liner assembly 12 into a cooking cavity and a smoke baffle cavity. An installation port 1521 is located at the lower end of the upper smoke baffle section 152 and is configured to allow the free end of the exhaust port 144 of the baking pan device 14 to pass through. An exhaust port 1522 is located at the upper end of the upper smoke baffle section 152 or between the upper smoke baffle section 152 and the top of the inner liner assembly 12. In this embodiment, the exhaust port 1522 is located at the upper end of the upper smoke baffle section 152.

[0054] In this embodiment, the lower guide section 151 and the upper smoke-blocking section 152 are set at an obtuse angle. The lower guide section 151 is arranged inclined downwards and backwards to facilitate the rapid diversion of the heat from the combustion flue gas to the bottom of the baking pan device 14, thus allowing for faster heating of the food inside the baking pan device 14. A rearwardly extending lower mounting surface 1511 is fixedly provided at the lower end of the lower guide section 151, and the lower mounting surface 1511 is connected and fixedly connected to the bottom of the inner liner assembly 12. An upper mounting surface 1524 extending forwards or backwards is fixedly provided at the top of the upper smoke-blocking section 152, and the upper mounting surface 1524 is connected and fixedly connected to the top of the inner liner assembly 12.

[0055] Specifically, an annular flange 1523 extending rearward is integrally formed around the periphery of the mounting opening 1521 to strengthen the smoke baffle and further reliably support the exhaust port 144 of the baking tray device 14. The exhaust port 1522 is arranged at an upward and rearward angle so that the exhaust port itself can act as a guide to facilitate rapid smoke exhaust and reduce mutual interference between cooking fumes and combustion fumes; and / or the diameter of the exhaust port 1522 gradually increases from bottom to top to facilitate rapid smoke exhaust. In this embodiment, the exhaust port 1522 includes a lower bottom surface 1531 and two side surfaces 1532. The lower bottom surface 1531 is arranged obliquely upward and backward, and its higher end extends toward the exhaust port 123. The top of the higher end of the lower bottom surface 1531 is in clearance fit or abuts against the lower end surface of the exhaust port 123. The two side surfaces 1532 are formed by the left and right ends of the lower bottom surface 1531 facing upward and outward, or by bending, so that the two side surfaces 1532 surround each other to form an inverted "V" shape.

[0056] The above are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
