Detailed Implementation

[0024] 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.

[0025] Example 1

[0026] refer to Figures 1-4This embodiment provides a smoke baffle 15, which includes a lower guide section 151 and an upper smoke baffle section 152 fixedly connected and angled. The lower guide section 151 is located below the upper smoke baffle section 152 and connected to the bottom of the upper smoke baffle section 152. An exhaust port 1522 and a mounting port 1521 are respectively provided at the upper and lower ends of the upper smoke baffle section 152. The exhaust port 1522 is used for the combustion smoke generated by the gas oven 1, while the mounting port 1521 is used for the exhaust port 144 of the baking tray device 14 in the gas oven 1 to pass through. Furthermore, an upwardly extending diversion surface 1533 is fixed at the rear end of the exhaust port 1522 to reduce mutual interference between the combustion smoke and cooking smoke at the exhaust port 144, and to avoid smoke collision, turbulence, or backflow.

[0027] refer to Figures 1-2 When the smoke baffle 15 is installed inside the inner cavity assembly 1 of the gas oven 1, the smoke baffle 15 can divide the interior of the inner cavity assembly 1 into a cooking cavity 121 and a smoke baffle cavity 122. The diversion surface 1533 on the smoke baffle 15 can divide the lower end face of the exhaust port at the top of the inner cavity assembly 1 into two parts, the front part is used to connect with the cooking cavity 121 through the exhaust port 1522, and the rear part is used to connect with the smoke baffle cavity 122, thereby ensuring that the smoke from the smoke baffle cavity 122 and the cooking cavity 121 do not interfere with each other before entering the exhaust port 143. The baking tray device 14 is placed inside the cooking cavity 121 and has a cooking space 143 and an exhaust port 144. The exhaust port 144 extends into the mounting port 1521, and the cooking space 143 is connected to the smoke baffle cavity 122 through the exhaust port 144. As can be seen, the setting of the smoke baffle 15 makes the cooking cavity 121 and the smoke baffle 122 independent of each other, which helps to reduce the mutual interference between cooking fumes and combustion fumes. At the same time, it can also prevent cooking fumes from polluting the cooking cavity 121 and combustion device in the gas oven 1, making the cooking cavity 121 easier to clean.

[0028] refer to Figures 2-4 The lower guide section 151 and the upper smoke-blocking section 152 are set at an obtuse angle. The upper smoke-blocking section 152 is arranged vertically to reduce the deposition of combustion smoke and cooking fumes on its surface; the lower guide section 151 is arranged at an angle to the rear and downward, so that the high-temperature smoke from the gas combustion can rise quickly, making it easier to quickly guide the heat of the combustion smoke to the bottom of the baking pan device 14 located in the cooking cavity 121, thus heating the food in the baking pan device 14 more quickly.

[0029] The lower guide section 151 and the upper smoke-blocking section 152 are integrally formed for rapid processing. A rearwardly extending lower mounting surface 1511 is fixed at the bottom of the lower guide section 151, configured to connect and fix it to the rear side of the bottom of the inner liner assembly 12. An upper mounting surface 1524 extending forward or rearward is fixed at the top of the upper smoke-blocking section 152, configured to connect and fix it to the top of the inner liner assembly 12.

[0030] refer to Figures 2-4 An annular flange 1523 extending rearward is integrally formed around the periphery of the mounting opening 1521 to strengthen the fume hood 14 and to further reliably support the vent 144 of the baking tray assembly 14 (see [reference]). Figure 2 The exhaust port 1522 is arranged at an upward and backward angle so that the exhaust port itself can act as a guide to facilitate rapid smoke exhaust, while also helping to reduce the 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.

[0031] The exhaust port 1522 includes a lower bottom surface 1531 and two side surfaces 1532. The lower bottom surface 1531 is arranged at an upward and rearward angle, which allows it to guide airflow and also allows the exhaust port 1522 to be arranged at an upward and rearward angle. The two side surfaces 1532 are respectively connected to the left and right ends of the lower bottom surface 1531. In this embodiment, 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 enclose each other to form an inverted "V" shape. This allows the two side surfaces 1532 to guide airflow and also allows the diameter of the exhaust port 1522 to gradually increase from bottom to top.

[0032] The lower end of the diversion surface 1533 is fixedly connected to the rear end of the bottom surface 1531, and the left and right ends of the diversion surface 1533 are fixedly connected to the rear ends of the two side surfaces 1532 respectively. In this embodiment, the diversion surface 1533 is integrally formed with the bottom surface 1531 and the two side surfaces 1532 respectively. In addition, at least one diversion part 1534 extending upward is provided on the top of the diversion surface 1533. The diversion part 1534 is used to divide the exhaust port 123 of the gas oven 1 into a front exhaust port and a rear exhaust port. The front exhaust port is connected to the cooking cavity 121 through the exhaust port 144, and the rear exhaust port is directly connected to the smoke baffle 122. This achieves the diversion of the flue gas in the cooking cavity 121 and the smoke baffle 122 in the exhaust port, avoiding flue gas collision, turbulence or backflow.

[0033] Example 2

[0034] refer to Figures 1-2This embodiment 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), a baking tray device 14, and a smoke baffle as described in Embodiment 1. The inner cavity assembly 12 is disposed inside the outer shell assembly 11 and has a cavity with a forward opening. At least one exhaust port 123 is provided at the top or upper back of the inner cavity assembly 12. The smoke baffle 15 is disposed inside the cavity and its upper end is connected to the top of the inner cavity assembly 12, and its lower end is 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 chamber 121 and a smoke baffle chamber 122 arranged at intervals. The smoke baffle chamber 122 is connected to at least one exhaust port 123, so that the cooking fumes in the smoke baffle chamber 122 can be discharged upward in a timely manner through the exhaust port 123. The cooking cavity 121 is connected to the exhaust port 123 through the exhaust port 1522, so that the combustion flue gas in the cooking cavity 121 can be discharged upward from the exhaust port 123 through the exhaust port 1522.

[0035] Support portions (not shown in the figure) are provided on the left and right sides of the cooking cavity 121. The support portions are configured to reliably support the baking tray device 14. The door assembly 17 is rotatably connected to the inner liner assembly 12 and is used to open or close the cooking cavity 121 of the inner liner assembly 12. The combustion device is disposed 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 tray device 14 is detachably placed in the cooking cavity 121, and its left and right ends abut against the support portions on the left and right sides of the cooking cavity 121. The baking tray device 14 has a sealed cooking space 143 and a vent 144. The free end of the vent 144 extends into the mounting port 1521. The cooking space 143 is connected to the smoke baffle chamber 122 through the vent 144.

[0036] When the combustion device operates, the combustion fumes fill the entire cooking cavity 121, heating the baking pan device. The condensed fumes and exhaust gases produced during combustion pass through the exhaust port 1522 at the rear of the top of the cooking cavity, and then are discharged upwards from the exhaust port 123. Meanwhile, the cooking fumes and oil vapors produced during cooking enter the smoke-blocking chamber 121 through the exhaust port 144 of the baking pan device 14, and then continue upwards into the exhaust port 123. Thus, firstly, it prevents the combustion fumes from contacting the food in the baking pan device 14, reducing the generation of harmful substances in the food; secondly, it isolates the cooking cavity 121 and the combustion device from cooking fumes, preventing grease and oil droplets produced 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 buildup. At the same time, it makes the cooking cavity 121 easier to clean.

[0037] refer toFigures 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 of the outer shell assembly 11 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.

[0038] refer to Figures 2-3 The top of the diversion surface 1533 of the smoke baffle 15 abuts against the top of the inner liner assembly 12, and the diversion surface 1533 divides the lower end face of at least one exhaust port 123 into front and rear parts. The front part is connected to the cooking cavity 121 through the exhaust port 1522, and the rear part is connected to the smoke baffle cavity 122. In addition, a diversion part 1534 is provided at the top of the diversion surface 1533 corresponding to the position of the exhaust port 123, extending upward. The diversion part 1534 extends into the exhaust port 123 and divides the exhaust port 123 into a front exhaust port and a rear exhaust port. The front exhaust port is connected to the cooking cavity 121 through the exhaust port 1522, and the rear exhaust port is directly connected to the smoke baffle cavity 122. In this way, the smoke from the cooking cavity 121 and the smoke baffle cavity 122 can be diverted within the exhaust port 123 to avoid smoke collision, turbulence, or backflow.

[0039] refer to Figures 1-2 Furthermore, 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.
