[0032] The burner 100 and the cooking device according to an embodiment of the present utility model will be described below with reference to the drawings.

[0033] As Figure 1 、 Figure 2 shown, the burner 100 according to an embodiment of the present utility model includes a furnace body 10 and a cooling chamber 20. A combustion chamber 11 is provided in the furnace body 10, and the combustion chamber 11 has an opening 12. A cooling chamber 21 is provided in the cooling chamber 20. The cooling chamber 20 is provided with a flue gas inlet 22, a cold air inlet 23, and a mixing outlet 24 that communicate with the cooling chamber 21. The flue gas inlet 22 communicates with the opening 12 of the combustion chamber 11 to convey the flue gas generated after combustion to the cooling chamber 21, and the cold air inlet 23 is used to convey external cold air into the cooling chamber 21.

[0034] Among them, the flue gas inlet 22 and the mixing outlet 24 are provided on both sides of the cooling chamber 20 along a first direction, and the cold air inlet 23 is provided on one side of the cooling chamber 20 along a second direction, and the second direction has an included angle with the first direction.

[0035] It should be noted that the temperature of the external air of the furnace body 10 and the cooling chamber 20 is lower than the temperature of the flue gas. That is, the air outside the cooling chamber 20 can enter the cooling chamber 20 as cold air from the cold air inlet 23 to cool the flue gas. In this application, the temperature of the cold air is not limited, as long as it is lower than the temperature of the flue gas and can be mixed with the flue gas to form a mixed gas and achieve temperature reduction.

[0036] It can be understood that the air can enter the cooling chamber 20 along the second direction through the cold air inlet 23, and the flue gas enters the cooling chamber 20 along the first direction from the flue gas inlet 22. Under the action of inertia, the flue gas passes through the cooling chamber 20 along the first direction and forms a mixed gas after mixing with the cold air and then flows to the mixing outlet 24.

[0037] Thus, in the cooling chamber 20, the cold air flows along the second direction and the flue gas flows along the first direction, so that there is an included angle between the flow directions of the cold air and the flue gas, which is beneficial to the full mixing of the cold air and the flue gas, improves the cooling effect of the cold air on the flue gas, and reduces or avoids local overheating caused by the flue gas not being mixed with cold air locally. At the same time, the cold air can flow to different positions of the flue gas in the second direction, so that the flue gas at different positions in the second direction can be mixed with cold air for temperature reduction, thereby improving the uniformity of the cold air cooling the flue gas, that is, improving the temperature uniformity of the mixed gas discharged from the mixing outlet 24.

[0038] In this application, the included angle between the first direction and the second direction, as well as the specific directions of the first direction and the second direction are not limited. For example, in Figures 1-4 the example, the first direction is along the vertical direction, the second direction is along the horizontal direction, and the first direction is perpendicular to the second direction in a straight line.

[0039] In some embodiments, as Figures 1-4 shown, there are at least two mixing outlets 24, and the burner 100 further includes: a flow splitting assembly 30, which is arranged in the cooling cavity 21. The projection of the flow splitting assembly 30 on the plane where the cold air inlet 23 is located is at least partially within the range of the cold air inlet 23 to split the cold air and direct it to different mixing outlets 24.

[0040] It can be understood that after the cold air enters the cooling chamber 20 from the cold air inlet 23, the cold air will flow in the cooling chamber 20 along the second direction under the action of inertia. With the continuous input of the cold air from the cold air inlet 23, it is easy to cause a larger amount of cold air at positions farther away from the cold air inlet 23 along the second direction in the cooling chamber 20, resulting in the temperature of the mixed gas formed after the cold air and the flue gas are mixed gradually decreasing in the direction away from the cold air inlet 23 along the second direction, thus affecting the temperature uniformity of the mixed gas.

[0041] Therefore, the projection of the flow splitting component 30 on the plane where the cold air inlet 23 is located is at least partially within the range of the cold air inlet 23, so that the flow of the cold air in the second direction can be blocked by the flow splitting component 30, thereby reducing the continuous flow of the cold air in the second direction, improving the uniformity of the cold air volume at different positions away from the cold air inlet 23 in the second direction, and thus improving the temperature uniformity of the mixed gas after the flue gas and the cold air are mixed. At the same time, the flow splitting component 30 splits and guides the cold air to different mixing outlets 24, making the cold air volume flowing to different mixing outlets 24 more uniform, thereby improving the temperature uniformity of the flue gas discharged from different mixing outlets 24.

[0042] In addition, the flow splitting component 30 can also have a guiding function, so as to split and guide the mixed gas to different mixing outlets 24, reduce or avoid the concentrated discharge of the mixed air from a small number of mixing outlets 24, make the mixed gas volume flowing to different mixing outlets 24 more uniform, and improve the efficiency of the mixed gas discharged from the plurality of mixing outlets 24 out of the cooling chamber 21.

[0043] Furthermore, the flow splitting component 30 includes a flow splitting body provided between two adjacent mixing outlets 24, and the flow splitting body is a flow splitting plate 31 or a flow splitting block. It can be understood that the mixing outlet 24 closer to the cold air inlet 23 in the second direction is the previous mixing outlet 24, and when no flow splitting body is provided, as the cold air continuously flows in the second direction, more cold air flows to the latter mixing outlet 24.

[0044] Therefore, the flow splitting body is located between two mixing outlets 24, and the flow splitting body can block part of the cold air, so that the blocked cold air can change the flow direction, which is beneficial to the cold air flowing to the previous mixing outlet 24, thereby increasing the cold air volume at the previous mixing outlet 24 and reducing the cold air volume at the latter mixing outlet 24, making the cold air volumes at the two mixing outlets 24 more uniform, thereby improving the uniformity of the flue gas cooled by the cold air at the two mixing outlets 24 and improving the temperature uniformity of the mixed gas discharged from the mixing outlet 24.

[0045] In this application, as Figure 1 shown, the flow splitting body can adopt the flow splitting plate 31. Alternatively, the flow splitting body can adopt the flow splitting block. Or, when there are multiple flow splitting bodies, some flow splitting bodies are flow splitting plates 31 and the other part of the flow splitting bodies are flow splitting blocks.

[0046] Furthermore, at least two mixing outlets 24 are arranged at intervals in the second direction. Among two adjacent mixing outlets 24, the mixing outlet 24 closer to the cold air inlet 23 is the upstream outlet, and the mixing outlet 24 farther from the cold air inlet 23 is the downstream outlet. The distance between the flow splitting body and the upstream outlet is less than the distance between the flow splitting body and the downstream outlet.

[0047] It can be understood that as the cold air continuously flows along the second direction, when the fluid splitter is not provided, the amount of cold air at the downstream outlet is greater than that at the upstream outlet.

[0048] Therefore, by setting the distance between the fluid splitter and the upstream outlet to be less than the distance between the fluid splitter and the downstream outlet, the distance that the cold air blocked by the fluid splitter flows to the upstream outlet is less than the distance it flows to the downstream outlet. Thus, the cold air is more likely to flow to the upstream outlet, increasing the amount of cold air flowing to the upstream outlet, further improving the uniformity of the cold air volume at the upstream outlet and the downstream outlet, and enhancing the temperature uniformity of the mixed gas discharged from the upstream outlet and the downstream outlet.

[0049] In some embodiments, as Figure 1 shown, there are at least three mixing outlets 24 arranged at intervals along the second direction, and at least two fluid splitters arranged at intervals along the second direction. Among the inner surfaces of the cooling chamber 21, the inner surface where the mixing outlet 24 is provided is the smoke outlet surface 25. The fluid splitter includes a first fluid splitter connected to the smoke outlet surface 25 and a second fluid splitter spaced apart from the smoke outlet surface 25. The first fluid splitter and the second fluid splitter are alternately arranged along the second direction.

[0050] It can be understood that the cold air flowing along the second direction can be blocked by the first fluid splitter and the second fluid splitter. The first fluid splitter is connected to the smoke outlet surface 25, and the second fluid splitter is spaced apart from the smoke outlet surface 25, that is, the first fluid splitter and the second fluid splitter are located at different positions in the first direction.

[0051] Therefore, the first fluid splitter and the second fluid splitter blocking the flow of the cold air in different positions in the first direction can reduce the flow velocity of the cold air along the second direction and block more cold air on the side of the first fluid splitter and the second fluid splitter facing the cold air inlet 23, thereby improving the uniformity of the cold air distribution at different positions along the second direction, and further enhancing the temperature uniformity of the mixed gas formed by the mixing of the cold air and the flue gas.

[0052] It should be noted that the number of fluid splitters can be set according to the number of mixing outlets 24. For example, in the Figure 1 example, the number of mixing outlets 24 is three, and the corresponding number of fluid splitters is set to two.

[0053] Preferably, the number of fluid splitters is one less than the number of mixing outlets 24.

[0054] Furthermore, the first sub-fluid is spaced apart from the flue gas inlet 22, and the second sub-fluid is provided at the flue gas inlet 22. The flue gas inlet 22 is elongated and extends along the second direction. The projection of each mixing outlet 24 along the second direction is at least partially within the range of the flue gas inlet 22, so that the flue gas entering the cooling chamber 21 from the flue gas inlet can maintain a flow along the first direction to the mixing outlet 24, improving the consistency of the flow direction of the flue gas or the mixed gas in the cooling chamber 21, reducing or avoiding the generation of eddy currents of the flue gas and the mixed gas in the cooling chamber 21, and improving the flow efficiency of the flue gas and the mixed gas, that is, improving the efficiency of the mixed gas discharged from the mixing outlet 24.

[0055] In some embodiments, as Figure 1 shown, the sub-fluid is a flow dividing plate 31 extending along the first direction. Thus, after the flue gas enters the cooling chamber 21 from the flue gas inlet 22, the flow dividing plate 31 can guide the flue gas, enabling the flue gas to flow in the cooling chamber 21 along the first direction, thereby improving the consistency of the flue gas flow direction, facilitating the full mixing of the flue gas with the cold air flowing along the second direction, and improving the cooling effect on the flue gas.

[0056] In some embodiments, as Figure 1 shown, both the furnace body 10 and the cooling chamber 20 are elongated and extend along the second direction, which can reduce the flow distance of the flue gas along the first direction and is beneficial to reducing the change in the flue gas flow direction. At the same time, the cold air has a relatively large flow distance along the second direction, enabling the flue gas to have more positions to mix with the cold air in the second direction, thereby improving the mixing efficiency of the cold air and the flue gas, that is, improving the cooling effect of the cold air on the flue gas.

[0057] In addition, the flue gas has a relatively large flow area between the furnace body 10 and the cooling chamber 20, which can improve the efficiency of the flue gas entering the cooling chamber 21 from the flue gas inlet 22.

[0058] Preferably, the size of the cooling chamber 20 along the second direction is less than or equal to 280 mm.

[0059] In some embodiments, as Figures 1-4 shown, the burner 100 further includes a air supply device 40, and the air outlet end 41 of the air supply device 40 is communicated with the cold air inlet 23. Thus, the air supply device 40 is used to drive the cold air to flow and enter the cooling chamber 21 from the cold air inlet 23 to ensure that the cold air can have kinetic energy to flow along the second direction after flowing into the cooling chamber 21 from the cold air inlet 23.

[0060] Preferably, the air outlet end 41 is located on the side of the cold air inlet 23 along the second direction away from the cooling chamber 21, so that the cold air can flow from the air outlet end 41 to the cold air inlet 23 along the second direction, further improving the consistency of the cold air flow direction.

[0061] In some embodiments, as Figure 1 shown, the burner 100 further includes: a gas distribution plate 50 and a gas mixing tank 60. The gas distribution plate 50 is disposed on a side of the furnace body 10 away from the cooling chamber 20, and the gas mixing tank 60 is disposed on a side of the gas distribution plate 50 away from the furnace body 10. Among them, the gas mixing tank 60 is communicated with the gas distribution plate 50 to supply combustion gas to the gas distribution plate 50, and the gas distribution plate 50 is communicated with the furnace body 10 to uniformly transport the combustion gas into the combustion chamber 11 in the furnace body 10. Thus, the combustion gas can flow from the gas mixing tank 60 to the gas distribution plate 50 in the first direction, and flow from the gas distribution plate 50 to the combustion chamber 11 in the first direction, which is beneficial to reducing the flow resistance of the combustion gas and improving the transportation efficiency of the combustion gas.

[0062] In addition, when the combustion gas burns to form flue gas in the combustion chamber 11, the flue gas can continue to flow in the first direction to the cooling chamber 20 for cooling, and finally flow out from the mixing outlet 24 in the first direction, which can also reduce the flow resistance of the flue gas and improve the transportation efficiency of the flue gas. Thus, the overall flow efficiency of the gas in the burner 100 is improved.

[0063] Furthermore, the gas mixing tank 60 further includes a gas inlet and an air inlet, and the gas inlet and the air inlet are oppositely arranged. Thus, after the gas and air enter the gas mixing tank 60, they can be fully mixed to form combustion gas, and the combustion gas enters the furnace body 10 through the gas distribution plate 50 and burns in the combustion chamber 11.

[0064] In some embodiments, as Figure 1 shown, the burner 100 further includes: an ignition needle 70. The ignition needle 70 penetrates through the gas distribution plate 50, and the ignition end of the ignition needle 70 is located in the combustion chamber 11 to ignite the combustion air in the combustion chamber 11.

[0065] The cooking device according to an embodiment of the present invention includes: the burner 100 of the above embodiment.

[0066] The cooking device of the present application, by adopting the burner 100 of the above embodiment, in the cooling chamber 20, the cold air flows in the second direction, and the flue gas flows in the first direction, so that the flow directions of the cold air and the flue gas form an angle, which is beneficial to the full mixing of the cold air and the flue gas, improves the cooling effect of the cold air on the flue gas, and reduces or avoids local overheating caused by the flue gas not being mixed with cold air locally. At the same time, the cold air can flow to different positions of the flue gas in the second direction, so that the flue gas at different positions in the second direction can be mixed with cold air for cooling, thereby improving the uniformity of the cold air cooling the flue gas, that is, improving the temperature uniformity of the mixed gas discharged from the mixing outlet 24.
