[0032] Reference is made to Figure 1 , Figure 1 is a schematic diagram of a disassembled structure of a burner provided in the present application. The present application provides a burner 100. The burner 100 is used to be arranged in a cooking device 1000. The cooking device 1000 can be an oven, a smoking and roasting all-in-one machine, or a gas stove, but is not limited thereto. Embodiments of the present application take the cooking device 1000 as an oven for example. The burner 100 is used to ignite fuel, and radiate heat generated by burning the fuel to the cooking cavity 10a of the cooking device 1000 in the form of infrared radiation, so as to cook food in the cooking cavity 10a.

[0033] Reference is made to Figures 2-3 , Figure 2 is a schematic diagram of a three-dimensional structure of a burner provided in the present application; Figure 3 is an enlarged view of A part in Figure 2 . The burner 100 comprises a first shell 110, a second shell 120, and a combustion assembly 130. The first shell 110 is provided with a receiving cavity 111, an opening 112 and a first flow channel 113 in communication with the receiving cavity 111. The second shell 120 is provided with a second flow channel 121. The second shell 120 covers the opening 112. The side wall of the first flow channel 113 and the side wall of the second flow channel 121 jointly form an ejector flow channel 110a, and the ejector flow channel 110a is in communication with the receiving cavity 111. The combustion assembly 130 is arranged on a side of the second shell 120 away from the first shell 110. The second shell 120 is provided with a first opening 120a in communication with the receiving cavity 111, for guiding fluid in the receiving cavity 111 to the combustion assembly 130.

[0034] In the present application, the fluid can be a mixed fluid of fuel and combustion-supporting agent such as air. The injection flow channel 110a is used to introduce the mixed fluid of fuel and combustion-supporting agent such as air into the accommodating cavity 111, so that the fuel and combustion-supporting agent such as air can be fully mixed, thereby improving the utilization rate of fuel and the combustion efficiency, and reducing the generation of pollutants such as nitrogen oxides and carbon monoxide. The mixed fluid entering the accommodating cavity 111 from the injection flow channel 110a can pass through the first opening 120a on the second shell 120 and be fully mixed, and finally flow to the combustion assembly 130. The combustion assembly 130 is used to ignite the fuel, and radiate the heat generated by the combustion of the fuel to the cooking cavity 10a in the form of infrared radiation, so as to cook the food in the cooking cavity 10a. By forming the accommodating cavity 111 and the first flow channel 113 of the first shell 110 in communication with each other, and forming the injection flow channel 110a by the side wall of the first flow channel 113 and the side wall of the second flow channel 121, not only can the problem of poor sealing and easy leakage of fuel at the connection between the existing injection pipe and the burner be improved, but also the smoothness of the connection between the injection flow channel 110a and the accommodating cavity 111 can be improved, thereby reducing the flow resistance of the fluid entering the accommodating cavity 111 from the injection flow channel 110a, and improving the injection effect.

[0035] The accommodating cavity 111 and the first flow channel 113 of the first shell 110 are in communication with each other, so that the connection between the injection flow channel 110a formed by the side wall of the first flow channel 113 and the side wall of the second flow channel 121 and the accommodating cavity 111 is smooth, thereby reducing the flow resistance of the fluid entering the accommodating cavity 111 from the injection flow channel 110a, and improving the injection effect.

[0036] In some embodiments, the combustion assembly 130 includes a flow distribution plate 131 and a radiating member 132. The flow distribution plate 131 is arranged in the accommodating cavity 111 and located on the side of the second shell 120 away from the first shell 110. The flow distribution plate 131 is provided with a second opening 131a communicating with the accommodating cavity 111. The diameter of the second opening 131a is smaller than the diameter of the first opening 120a. The radiating member 132 is arranged on the side of the flow distribution plate 131 away from the first shell 110. The radiating member 132 is a metal fiber material.

[0037] The shunt plate 131 is arranged on the side of the second shell 120 away from the first shell 110, and the radiating member 132 is arranged on the side of the shunt plate 131 away from the second shell 120, that is, the shunt plate 131 and the radiating member 132 are sequentially arranged on the side of the second shell 120 away from the first shell 110 to cover the opening 112 of the containing cavity 111. A plurality of second openings 131a are formed in the shunt plate 131 and communicate with the containing cavity 111, and the plurality of second openings 131a are uniformly distributed on the shunt plate 131. The diameter of the first opening 120a is much larger than the diameter of the second opening 131a. The first opening 120a is used for the mixed fluid of fuel and combustion-supporting agent such as air to pass through, so that the fuel and the combustion-supporting agent such as air can be fully mixed. The second opening 131a plays a role of shunting the fluid in the containing cavity 111, can divide the flow path of the fluid flowing from the containing cavity 111 to the radiating member 132, ensure that the fluid flow to different positions of the radiating member 132 is consistent, so that the heat radiated by the combustion assembly 130 to the cooking cavity 10a at different positions is the same, which is beneficial to improve the uniformity of heat distribution in the cooking cavity 10a. In addition, the second shell 120 can support the shunt plate 131, and the shunt plate 131 can support the radiating member 132, so that the structure of the shunt plate 131 and the radiating member 132 is more stable, and the stability of fuel combustion is enhanced.

[0038] The radiating member 132 is a metal fiber material. It should be noted that the metal fiber material can be formed by crossing, drying and sintering treatment of metal fibers, and the metal fibers can be fibers made of iron, nickel, chromium, aluminum and alloys thereof. The radiating member 132 is selected from the metal fiber material, so that the radiating member 132 has uniform air permeability, not only can radiate the heat generated by fuel combustion to the cooking cavity 10a in the form of infrared radiation, improve the heating uniformity, and reduce the generation of pollutants such as nitrogen oxides and carbon monoxide, but also has good corrosion resistance and oxidation resistance, can be used stably for a long time in a high-temperature environment, and has a long service life.

[0039] The first shell 110, the second shell 120 and the shunt plate 131 can be sheet metal parts made by cutting, bending, stamping, welding and the like. The material of any one of the first shell 110, the second shell 120 and the shunt plate 131 can be iron, nickel, chromium, aluminum or zinc and alloys thereof.

[0040] In some embodiments, the ratio of the distance between two adjacent second openings 131a to the diameter of the second opening 131a can be 1-2.

[0041] In some embodiments, the ratio of the distance between two adjacent second openings 131a on the flow distribution plate 131 to the diameter of the second openings 131a can be 1, 1.15, 1.186, 1.2, 1.23, 1.255, 1.28, 1.29, 1.3, 1.34, 1.365, 1.38, 1.4, 1.43, 1.456, 1.47, 1.5, 1.52, 1.55, 1.585, 1.6, 1.64, 1.665, 1.68, 1.7, 1.73, 1.75, 1.775, 1.8, 1.85, 1.865, 1.9, 1.93, 1.96, 2, or a range defined by any of the above values, for example, 1-1.5, 1-1.64, 1.2-1.5, 1.2-1.64, 1-2, 1.3-1.5, 1.5-1.8, 1.5-2, etc., as long as the ratio of the distance between two adjacent second openings 131a on the flow distribution plate 131 to the diameter of the second openings 131a is within the range of 1-2. Preferably, the ratio of the distance between two adjacent second openings 131a on the flow distribution plate 131 to the diameter of the second openings 131a is 1.5.

[0042] By making the ratio of the distance between two adjacent second openings 131a on the flow distribution plate 131 to the diameter of the second openings 131a be 1-2, it can ensure that the second openings 131a have a significant flow distribution effect on the fluid in the accommodation cavity 111, so that the fluid in the accommodation cavity 111 can uniformly pass through the flow distribution plate 131 through the second openings 131a of the flow distribution plate 131, thereby improving the consistency of the fluid flow to different positions of the radiating element 132.

[0043] In some embodiments, the first shell 110 includes a first main body portion 114 and a first extension portion 115 connected to the first main body portion 114. The first main body portion 114 forms the accommodation cavity 111. The first extension portion 115 forms the first flow channel 113. The second shell 120 includes a second main body portion 122 and a second extension portion 123 connected to the second main body portion 122. The second main body portion 122 is provided with the first opening 120a. The second extension portion 123 is provided with the second flow channel 121.

[0044] The first extension portion 115 extends from the outer edge of the first main body portion 114 away from the accommodation cavity 111. The accommodation cavity 111 is formed in the first main body portion 114. The first flow channel 113 is formed in the first extension portion 115. The first flow channel 113 communicates with the accommodation cavity 111. The second main body portion 122 cooperates with the first main body portion 114. The second extension portion 123 extends from the outer edge of the second main body portion 122 away from the accommodation cavity 111 and cooperates with the first extension portion 115. The first opening 120a is provided on the second main body portion 122. The second extension portion 123 protrudes relative to the second main body portion 122 in a direction away from the first shell 110 to form the second flow channel 121.

[0045] Please refer to Figures 4-5 , Figure 4 is a cross-sectional structural schematic diagram of a part of the burner provided in the present application; Figure 5 is Figure 4 an enlarged view of part B in FIG. 11. The first body part 114 cooperates with the second body part 122 to divide the accommodating cavity 111 into a first cavity 1111 and a second cavity 1112. The first cavity 1111 is located between the bottom wall of the accommodating cavity 111 and the second body part 122, and the second cavity 1112 is located between the second body part 122 and the flow dividing plate 131. The first cavity 1111 and the second cavity 1112 are communicated through the first opening 120a. The first extension part 115 cooperates with the first extension part 115 to communicate the first flow channel 113 and the second flow channel 121, so as to form an ejecting flow channel 110a. The ejecting flow channel 110a is communicated with the first cavity 1111 and the second cavity 1112 through the first opening 120a.

[0046] The first body part 114 and the second body part 122 can be annular body parts, and the accommodating cavity 111 of the first body part 114 can be an annular accommodating cavity. The ejecting flow channel 110a is used to introduce the fluid composed of air and fuel into the accommodating cavity 111. The annular structure of the accommodating cavity 111 is conducive to further mixing and diffusion of the fuel and the air, so that the fuel and the air can be mixed efficiently and fill the entire accommodating cavity 111, ensuring that the flow of the mixed fluid reaching different positions of the combustion assembly 130 is consistent, so that the heat radiated from different positions of the combustion assembly 130 to the cooking cavity 10a is the same, which helps to improve the temperature uniformity in the cooking cavity 10a, and at the same time, the combustion efficiency of the fuel can be improved, and the generation of pollutants such as nitrogen oxides and carbon monoxide can be reduced.

[0047] Please refer to Figure 6 , Figure 6 is a structural schematic diagram of an embodiment of the first shell of the burner provided in the present application. The ejecting flow channel 110a is located at a tangential position of the inner side wall of the first body part 114, and the connection between the inner side wall of the ejecting flow channel 110a and the inner side wall of the first body part 114 is smoothly arranged, so as to reduce the flow resistance of the fluid and improve the ejecting effect of the ejecting flow channel 110a on the fluid.

[0048] In some embodiments, the first body part 114 includes a bottom shell 1141 and a first side shell 1142. The first side shell 1142 is arranged around the outer periphery of the bottom shell 1141 and extends towards the combustion assembly 130. The central axis of the ejecting flow channel 110a is tangent to or intersects the inner side wall of the first side shell 1142.

[0049] The middle axis of the injection flow channel 110a is tangent to or intersects with the inner side wall of the first side shell 1142, so that the injection flow channel 110a can guide the fluid to be injected into the accommodating cavity 111 in a straight line, which not only reduces the flow resistance, but also enhances the injection capacity, thereby improving the injection effect. The connection between the first side shell 1142 and the bottom shell 1141 is smoothly arranged, which can reduce the friction force of the fluid at the connection between the first side shell 1142 and the bottom shell 1141, thereby reducing the flow resistance and friction noise of the fluid.

[0050] The middle axis of the injection flow channel 110a is tangent to or intersects with the inner side wall of the first side shell 1142. Specifically, the first side shell 1142 includes a first end 1142b and a second end 1142c arranged at intervals, and the first outer extension part 115 is connected between the first end 1142b and the second end 1142c. The first end 1142b is smoothly arranged with the inner wall of the injection flow channel 110a, and the middle axis of the injection flow channel 110a is tangent to or intersects with the inner side wall of the first side shell 1142 close to the first end 1142b, which not only reduces the flow resistance of the fluid, but also enhances the injection capacity, thereby improving the injection effect of the injection flow channel 110a on the fluid.

[0051] In some embodiments, please continue to refer to Figures 3-5 The second main body part 122 is formed with a recessed part 122a on the side away from the first shell 110. It can be understood that the second main body part 122 protrudes towards the first shell 110 to form the recessed part 122a. The second main body part 122 includes a support part 1221 and a first clamping part 1222. The support part 1221 is the bottom wall of the recessed part 122a. The first clamping part 1222 is formed on the periphery of the recessed part 122a close to the first side shell 1142. The periphery of the first side shell 1142 away from the bottom shell 1141 is formed with a first limiting groove 1142a. The first outer extension part 115 is formed with a second limiting groove 115a communicating with the first limiting groove 1142a. The first clamping part 1222 is embedded in the first limiting groove 1142a to divide the accommodating cavity 111 into a first cavity 1111 and a second cavity 1112. The second outer extension part 123 is embedded in the second limiting groove 115a to make the side wall of the first flow channel 113 and the side wall of the second flow channel 121 enclose the injection flow channel 110a.

[0052] Please refer to Figures 7-8 , Figure 7 is Figure 2 a sectional structure schematic view in a direction; Figure 8 is Figure 7The enlarged view of the C part in FIG. 11B. The combustor 100 further comprises a partition plate 140. The partition plate 140 is arranged on the side of the second shell 120 facing away from the first shell 110 and is embedded in the first limiting groove 1142a to form a third limiting groove 140a between the support portion 1221 and the partition plate 140 and a fourth limiting groove 140b between the partition plate 140 and the inner wall of the first limiting groove 1142a away from the bottom shell 1141. The flow splitter 131 is embedded in the third limiting groove 140a near the periphery of the first side shell 1142, and the radial member 132 is embedded in the fourth limiting groove 140b near the periphery of the first side shell 1142.

[0053] The opening of the first limiting groove 1142a faces the accommodating cavity 111, and the partition plate 140 is embedded in the first limiting groove 1142a through the opening of the first limiting groove 1142a to form a third limiting groove 140a between the support portion 1221 and the partition plate 140 and a fourth limiting groove 140b between the partition plate 140 and the inner wall of the first limiting groove 1142a away from the bottom shell 1141. The openings of the third limiting groove 140a and the fourth limiting groove 140b face the accommodating cavity 111. The thickness of the flow splitter 131 near the periphery of the first side shell 1142 is less than or equal to the height of the third limiting groove 140a in the direction from the first shell 110 to the combustion assembly 130, facilitating the embedding of the flow splitter 131 near the periphery of the first side shell 1142 in the third limiting groove 140a. The inner wall of the third limiting groove 140a can press the part of the flow splitter 131 in the third limiting groove 140a, thereby strengthening the stability and sealing performance of the structure, not only preventing the flow splitter 131 from coming out of the third limiting groove 140a, but also ensuring good sealing performance at the connection between the flow splitter 131 and the first shell 110 and the partition plate 140, preventing fluid leakage. The thickness of the radial member 132 near the periphery of the first side shell 1142 is less than or equal to the height of the fourth limiting groove 140b in the direction from the first shell 110 to the combustion assembly 130, facilitating the embedding of the radial member 132 near the periphery of the first side shell 1142 in the fourth limiting groove 140b. The inner wall of the fourth limiting groove 140b can press the part of the flow splitter 131 in the fourth limiting groove 140b, thereby strengthening the stability and sealing performance of the structure, not only preventing the radial member 132 from coming out of the fourth limiting groove 140b, but also ensuring good sealing performance at the connection between the radial member 132 and the first shell 110 and the partition plate 140, preventing fluid leakage.

[0054] In some embodiments, the first main body part 114 further comprises a second side shell 1143. The second side shell 1143 is arranged around the inner periphery of the bottom shell 1141 and extends towards the direction of the combustion assembly 130 to form the first air vent 110b. The connection between the second side shell 1143 and the bottom shell 1141 is smoothly transitioned, which on one hand can reduce the friction between the fluid and the connection between the second side shell 1143 and the bottom shell 1141, so as to reduce the flow resistance and friction noise of the fluid, and on the other hand is conducive to the sufficient mixing of the fuel and the combustion-supporting agent such as air. The second side shell 1143 is bent away from the periphery of the bottom shell 1141 towards one side of the accommodating cavity 111 to form a fifth limiting groove 1143b with the second shell 120. The second shell 120 can be fixed to the inner wall of the second side shell 1143 by welding, bonding, magnetic adsorption connection or the like. The flow distribution plate 131 and the radial member 132 are sequentially embedded in the fifth limiting groove 1143b near the periphery of the first air vent 110b.
