As shown in
In one embodiment, the top plate 23 is matched with the opening 212 of the box 21. An interior of the box 21 can communicate with the outside only through the set of intake holes 211 and the set of exhaust holes 231. The fire splitting assembly 24 is arranged in the box 21. The fire splitting assembly 24 and the top plate 23 form the exhaust passage 26 communicating with the set of exhaust holes 231. The fire splitting assembly 24 and the inner bottom surface of the box 21 form the intake passage 25 communicating with the set of intake holes 211. The first combustor 22 is arranged in the box 21 and is located between the intake passage 25 and the exhaust passage 26. When the first combustor 22 is used to heat the cooking apparatus 100, the air reaches the installation position of the first combustor 22 through the set of intake holes 211 and the intake passage 25, and the gas enters the box 21 through the first combustor 22 and is mixed with the air. After the combustible gas is ignited, combusting flames extend along the fire splitting assembly 24, and the heat generated after the combustion is radiated into the cooking cavity 11 through the top plate 23. The combustion exhaust gas enters the cooking cavity 11 through the exhaust passage 26 and the set of exhaust holes 231, and then is discharged through a smoke discharge passage of the cooking apparatus 100. The intake passage 25 and the exhaust passage 26 are arranged on both sides of the fire splitting assembly, and the intake passage 25 is located at a bottom of the exhaust passage 26. The intake process is smooth, and sufficient air can be provided to the first combustor 22 so that the air-fuel ratio is increased, and improving the power of the combustion device 1. In addition, the exhaust passage 26 is located at an upper part of the intake passage 25, which facilitates the discharge of the combustion exhaust gas, so that the gas can fully combust, the amount of smoke generated is reduced, and the thermal efficiency of the combustion device 1 is improved.
It should be understood that since the gas can fully combust, less smoke enters the cooking cavity 11, and avoiding the occurrence of carbon deposition in the cooking cavity 11, meeting the market's requirements on the cooking apparatus 100, and facilitating the promotion and popularization of the cooking apparatus 100.
It should be pointed out that the first combustor 22 is arranged in the box 21 and is located between the top plate 23 and the inner bottom surface of the box 21, the first combustor 22 is located in a middle position of the box 21, and the fire splitting assembly 24 is arranged between the top plate 23 and the inner bottom surface of the box 21, so that the intake passage 25 is located at the bottom of the first combustor 22, and the exhaust passage 26 is located at an upper part of the first combustor 22. Since both the air and the gas have a lift force, the air and the gas are mixed and combust at the position of the first combustor 22 so that sufficient combustion of the gas can be ensured. The generated combustion exhaust gas is discharged through the exhaust passage 26 and the set of exhaust holes 231 after ascending, so that the combustion exhaust gas can be fully discharged, the influence of the combustion exhaust gas on the first combustor 22 is avoided, and the combustion efficiency of the gas is improved.
In addition, an oil collecting groove 232 is provided on a top surface of the top plate 23 (a side surface away from the box 21). When the combustion device 1 is used to heat the cooking apparatus 100, the combustion device 1 is arranged at the bottom of the cooking cavity 11, and when the combustion device 1 is heating the cooking cavity 11, the top plate 23 has an ability to radiate heat into the cooking cavity 11. Since the top surface of the top plate 23 has the oil collecting groove 232, the area of the top plate 23 is increased, and at the same time, since it has a different angled side surface, the heat radiation ability of the top plate 23 is improved, so that the heating in the cooking cavity 11 is more uniform. In addition, liquid substances such as grease generated during the cooking process are collected in the oil collecting groove 232, which is easy to clean, and ensuring that the cooking cavity 11 has good sanitary conditions.

The first portion 3221 is arranged inclined to the main plate body 321, the first portion 3221 is inclined in a direction approaching the top plate 12 of the cooking cavity, and the second portion 3222 is inclined relative to the first portion 3221 and is inclined in a direction away from the top plate 12 of the cooking cavity. When the second combustor 31 is activated, the gas combusts to produce flames. The flames first flow through the first portion 3221, and then flow to the second portion 3222 through a connection position of the first portion 3221 and the second portion 3222. Since the first portion 3221 and the second portion 3222 form the first bend structures, the flow strokes of the flames are increased, so that the flames stay on the radiation plate 32 completely, the contact of the flames and the top plate 12 of the cooking cavity is avoided, and the temperature rise of the top plate 12 of the cooking cavity is further reduced.
It should be understood that when the flames flow along the first portion 3221 and the second portion 3222, the flames are turned multiple times, and improving the adhesion force between the flames and the first plate body 322, so that the flames can effectively flow in the bending direction of the first plate body 322, which further improves the diversion effect of the first plate body 322 on the flames, avoids the influence of the flames on the top plate 12 of the cooking cavity, enables the gas to fully combust, and reduces the amount of smoke generated.
It should be pointed out that the other end of the second portion 3222 is close to one side wall of the cooking cavity 11, and the second portion 3222 is arranged inclined to the side wall, to prevent the airflow after combustion from hitting the side wall and returning to the position of the first plate body 322 again to affect the combustion of the gas, so that the gas can fully combust, the amount of smoke generated is reduced, and the safety of the user is improved.

When the combustion device needs to be disassembled, for example, when a cabinet 10 of the cooking apparatus 100 needs to be repaired, the wiring terminal 42 of the combustion inductor 40 can be disconnected from the inductor body 41, so that the combustion device can be wholly disassembled without disassembling a rear plate of the cabinet 10 and related electrical components and circuits or moving the cabinet 10. Therefore, the disassembly and assembly operations are simplified, and the overall disassembly and removal of the combustion device are facilitated, which is especially suitable for a large-scale cooking apparatus 100, such as a built-in oven. In addition, since the wiring terminal 42 and the inductor body 41 are of a split structure, the restriction of the inductor body 41 to the material selection of the wiring terminal 42 is reduced, so that the wiring terminal 42 can be made of a material with a higher strength level, which is advantageous for improving the reliability of the wiring terminal 42 and which also facilitates processing and molding.

It can be understood that since the inductor body 41 needs to be made of a high-temperature resistant material, in a common integrated structure, the selection of materials for the wiring part is limited, and it is easy to cause damage during multiple disassembly and assembly processes. However, in this embodiment, since the wiring terminal 42 and the inductor body 41 are of a split structure, materials with a higher strength can be specially selected for the wiring terminal 42 to reduce the possibility of damage to the wiring terminal 42 and the wire harness during the disassembly and assembly process, which is advantageous for improving the reliability of the wiring terminal 42 and prolonging the overall life of the combustion inductor 40.
