Description

Technical Field

[0001] The present invention relates to the technical field of household electrical appliances, and in particular to a burner and a cooking utensil. Background Art

[0002] Existing infrared burners usually use ceramic materials to make the combustion surface. Infrared burners with this structure have the problem of complex structure, and because the ceramic plate transfers heat to the gas mixing chamber, flashback is prone to occur. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, the first object of the present invention is to provide a burner.

[0005] The second object of the present invention is to provide a cooking appliance.

[0006] To achieve at least one of the above-mentioned purposes, according to a first aspect of the present invention, a burner is proposed, comprising: a main body, including a gas containing chamber, the gas containing chamber being used to contain combustible gas; a combustion mesh assembly, the opening of the gas containing chamber being toward the combustion mesh assembly so that the combustible gas can burn on the surface of the combustion mesh assembly, the combustion mesh assembly being arranged toward the outside to radiate heat energy to the outside; a flashback barrier mesh assembly, located on the side of the combustion mesh assembly facing the main body, the flashback barrier mesh assembly being used to prevent the flame on the combustion mesh assembly from entering the gas containing chamber.

[0007] The burner proposed in the present application can be used in a cooking utensil. When the burner is in operation, it can heat the inside of the cooking utensil to heat and cook the food. The burner includes a main body, a combustion net assembly and a flashback barrier net assembly, wherein the main body includes a gas accommodating cavity, the gas accommodating cavity is used to accommodate combustible gas, the combustion material assembly is used to burn the combustible gas to increase the temperature of the combustion net assembly so that the combustion net assembly can radiate heat energy, and the flashback barrier net assembly is used to prevent flashback.

[0008] Specifically, a certain amount of combustible gas can be stored in the gas containing cavity, and the opening of the gas containing cavity faces the combustion object assembly so that the combustible gas can flow to the combustion net assembly. The combustible gas burns on the combustion net assembly, and the temperature of the flame combustion is above 800°C, so that the combustion net assembly is heated by the flame to form infrared heat radiation, so that the combustion net assembly can radiate heat energy.

[0009] Furthermore, in order to prevent the flame on the combustion net assembly from entering the gas containing chamber when flashback occurs, the present application also provides a flashback barrier net assembly on the side of the combustion net assembly facing the main body. When flashback occurs, the flashback barrier net can play a certain blocking role on the flame, preventing the flame from entering the gas containing chamber, thereby improving the safety of the burner.

[0010] Furthermore, the burner is also provided with an ignition device, which is arranged on the main body. The ignition device can ignite the combustible gas flowing to the combustion network component, so that the burner can operate normally and generate heat energy.

[0011] By arranging a combustion net assembly and a flashback barrier net assembly in the burner, the combustible gas can be burned on the combustion net assembly to increase the temperature of the combustion net assembly, so that the combustion net assembly can radiate heat energy, and the flashback barrier net assembly prevents the flame from entering the gas receiving chamber, thereby improving the safety of the burner. Compared with existing products, the burner proposed in this application has a simpler structure, lower manufacturing difficulty, reduced production costs, and higher safety and reliability.

[0012] According to the above-mentioned burner of the present invention, it can also have the following distinguishing technical features:

[0013] In some technical solutions, optionally, the burner further includes: a supporting mesh assembly installed between the combustion mesh assembly and the backfire barrier mesh assembly, and the supporting mesh assembly is used to support the combustion mesh assembly.

[0014] In this technical solution, the structure of the burner is defined. The burner also includes a support mesh assembly, which is used to support the combustion mesh assembly. Understandably, if the combustion mesh assembly is deformed, it will cause the flame on the surface of the combustion mesh assembly to be unstable, thereby affecting the heating effect. In order to prevent the combustion mesh assembly from deforming, the present application provides a support mesh assembly in the burner, which can support the combustion mesh assembly to prevent the combustion mesh assembly from deforming. The support mesh assembly can be made of a high-strength and high-temperature resistant material to improve the stability of the combustion mesh assembly.

[0015] By arranging a support mesh assembly in the burner for supporting the combustion mesh assembly, deformation of the combustion mesh assembly can be avoided, the stability of the combustion mesh assembly can be improved, and the flame can be ensured to burn stably on the combustion mesh assembly.

[0016] In some technical solutions, optionally, there is a distance between the tempering barrier mesh assembly and the supporting mesh assembly, and there is a distance between the supporting mesh assembly and the combustion mesh assembly.

[0017] In this technical solution, the support mesh assembly, the combustion mesh assembly and the flashback barrier mesh assembly are further defined. Specifically, there is a spacing between the support mesh assembly and the combustion mesh assembly, and there is a spacing between the support mesh assembly and the flashback barrier mesh assembly. In this way, it is equivalent to setting an air insulation layer between the support mesh assembly, the combustion mesh assembly and the flashback barrier mesh assembly. Compared with the structure in which the support mesh assembly, the combustion mesh assembly and the flashback barrier mesh assembly are arranged in close proximity, the present application can reduce the heat transfer between the support mesh assembly, the combustion mesh assembly and the flashback barrier mesh assembly, reduce the temperature of the flashback barrier mesh assembly, reduce the possibility of flashback, and improve the safety of the burner by setting a spacing between the support mesh assembly and the combustion mesh assembly and between the support mesh assembly and the flashback barrier mesh assembly.

[0018] In some technical solutions, optionally, the combustion net assembly includes at least one combustion net, the support net assembly includes at least one support net, the tempering barrier net assembly includes at least one tempering barrier net, and the combustion net, the support net and the tempering barrier net are made of metal material.

[0019] In this technical solution, the combustion net assembly, the support net assembly and the tempering barrier net assembly are further defined. Specifically, the combustion net assembly includes at least one combustion net, the support net assembly includes at least one support net, the tempering barrier net assembly includes at least one tempering barrier net, and the combustion net, the support net and the tempering barrier net are made of metal materials. By using metal materials to make the combustion net, the support net and the tempering barrier net, on the one hand, the strength of the combustion net, the support net and the tempering barrier net can be improved. Compared with the combustion plate made of ceramic material, the combustion net, the support net and the tempering barrier net in the burner proposed in this application have higher strength. On the other hand, the mesh structure of the metal material is easy to process and easy to assemble, thereby reducing the difficulty of production.

[0020] In some technical solutions, optionally, the mesh size of the combustion net ranges from 40 mesh to 200 mesh.

[0021] In this technical solution, the mesh number range of the combustion net is limited, specifically, the mesh number range of the combustion net is 40 mesh to 200 mesh. It can be understood that the combustion net is used to burn combustible gas to generate flames, which requires the flame to be stably distributed and burned on the combustion net, so the mesh number of the combustion net cannot be too small, otherwise it will cause uneven flames. Therefore, the present application sets the mesh number of the combustion net in the range of 40 mesh to 200 mesh to ensure that the flame on the combustion net remains stable.

[0022] In some technical solutions, optionally, the mesh number of the support net ranges from 5 mesh to 40 mesh.

[0023] In this technical solution, the mesh number range of the support net is limited, specifically, the mesh number range of the support net is 5 mesh to 40 mesh. Since the support net is arranged between the combustion net and the gas containing cavity, the combustible gas needs to pass through the support net to reach the combustion net, so the support net needs to be set as a mesh structure with a large mesh size and a small mesh number. For this reason, the present application sets the mesh number of the support net in the range of 5 mesh to 40 mesh to ensure that the combustible gas can smoothly pass through the support net.

[0024] In some technical solutions, optionally, the mesh size of the tempered barrier net ranges from 40 mesh to 200 mesh.

[0025] In this technical solution, the mesh number range of the tempering barrier net is limited, specifically, the mesh number range of the tempering barrier net is 40 mesh to 200 mesh. The tempering barrier net is used to prevent tempering, so it is necessary to set the tempering barrier net to a mesh structure with a larger mesh number. For this reason, the present application sets the mesh number of the tempering barrier net to be within the range of 40 mesh to 200 mesh to improve the barrier effect of the tempering barrier net.

[0026] In some technical solutions, optionally, the thickness of the combustion net ranges from 0.1 mm to 0.5 mm.

[0027] In this technical solution, the thickness of the combustion net is limited, specifically, the thickness range of the combustion net is 0.1mm to 0.5mm. In this way, the problem of increased product volume due to excessive thickness of the combustion net can be avoided while ensuring that the strength of the combustion net meets the use requirements.

[0028] In some technical solutions, optionally, the thickness of the support mesh ranges from 0.2 mm to 2 mm.

[0029] In this technical solution, the thickness of the support net is limited. Specifically, the thickness of the support net ranges from 0.2 mm to 2 mm. It can be understood that the function of the support net is to support the combustion net. Therefore, if the strength of the support net is too low, the support effect of the support net will be poor, which will cause the combustion net to deform. Therefore, this application limits the thickness of the support net to a range of 0.2 mm to 2 mm to ensure that the strength of the support net meets the use requirements. In addition, by making the support net have a certain thickness, the support net can also have a certain heat insulation effect.

[0030] In some technical solutions, optionally, the tempered barrier mesh has a thickness ranging from 0.1 mm to 0.5 mm.

[0031] In this technical solution, the thickness range of the tempered barrier net is limited. Specifically, the thickness range of the tempered barrier net is 0.1 mm to 0.5 mm. In this way, the problem of increased product volume due to excessive thickness of the tempered barrier net can be avoided while ensuring that the strength of the tempered barrier net meets the use requirements.

[0032] In some technical solutions, optionally, the main body includes: a shell; a guide plate connected to the shell, the shell and the guide plate together form a gas containing chamber, the guide plate has a plurality of guide holes, and the guide holes are used to discharge the combustible gas in the gas containing chamber to the combustion network assembly.

[0033] In this technical solution, the structure of the main body is defined. The main body includes a shell and a guide plate, wherein the guide plate is connected to the shell, and the guide plate and the shell together form a gas containing chamber, and the gas containing chamber can contain a certain amount of combustible gas. Furthermore, the guide plate has a plurality of guide holes, and the combustible gas in the gas containing chamber can flow to the combustion net assembly through the guide holes, so that the combustible gas can burn on the combustion net assembly, increase the temperature of the combustion net assembly, and then the combustion net assembly can radiate heat energy. The guide holes can guide the combustible gas. Since the combustible gas flows to the combustion net assembly through the guide holes, the combustible gas can flow to the combustion net assembly more evenly by rationalizing the positions of the plurality of guide holes, thereby avoiding uneven flame distribution at various positions on the combustion net assembly and keeping the temperature at various positions of the combustion net assembly uniform.

[0034] In some technical solutions, optionally, a plurality of guide holes are evenly distributed on the guide plate.

[0035] In this technical solution, the setting positions of the plurality of guide holes are limited, and specifically, the plurality of guide holes are evenly distributed on the guide plate. Since the combustible gas flows to the combustion net assembly through the guide holes, the combustible gas can flow to the combustion net assembly more evenly by evenly distributing the plurality of guide holes on the guide plate, thereby avoiding uneven flame distribution at various positions on the combustion net assembly and maintaining uniform temperature at various positions of the combustion net assembly.

[0036] In some technical solutions, optionally, the burner further includes: a gas pipe connected to the shell and communicated with the gas containing chamber, and the gas pipe is used to input combustible gas into the gas containing chamber.

[0037] In this technical solution, the structure of the burner is further defined, and the burner also includes a gas pipe, which is used to input combustible gas into the gas containing chamber. Specifically, the gas pipe is connected to the shell and communicates with the gas containing chamber, and the combustible gas flows into the gas containing chamber through the gas pipe. The gas pipe extends into the gas containing chamber to discharge the combustible gas from the central area of ​​the gas containing chamber into the gas containing chamber, so that the concentration of combustible gas in various parts of the gas containing chamber tends to be balanced, so that the combustible gas can flow to the combustion net assembly more evenly, thereby improving the uniformity of the flame on the combustion net assembly.

[0038] The second aspect of the present invention further provides a cooking appliance, comprising the burner provided by the first aspect of the present invention.

[0039] The cooking appliance provided in the second aspect of the present invention comprises the burner provided in the first aspect of the present invention, and thus has all the beneficial effects of the burner.

[0040] Cooking appliances include a pizza oven.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0052] Refer to the following Figures 1 to 5 A burner 100 and a cooking appliance provided according to some embodiments of the present invention are described.

[0053] In one embodiment according to the present application, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention proposes a burner 100, including: a main body 110, including a gas containing chamber 111, the gas containing chamber 111 is used to contain combustible gas; a combustion mesh assembly 120, the opening of the gas containing chamber 111 is toward the combustion mesh assembly 120, so that the combustible gas can burn on the surface of the combustion mesh assembly 120, and the combustion mesh assembly 120 is arranged to face the outside to radiate heat energy to the outside; a flashback barrier mesh assembly 130, located on the side of the combustion mesh assembly 120 facing the main body 110, and the flashback barrier mesh assembly 130 is used to prevent the flame on the combustion mesh assembly 120 from entering the gas containing chamber 111.

[0054] The burner 100 proposed in the present application can be used in a cooking utensil. When the burner 100 is in operation, it can heat the inside of the cooking utensil to heat and cook the food. The burner 100 includes a main body 110, a combustion net assembly 120 and a flashback barrier net assembly 130, wherein the main body 110 includes a gas receiving chamber 111, the gas receiving chamber 111 is used to receive combustible gas, the combustion assembly is used to burn the combustible gas to increase the temperature of the combustion net assembly 120, so that the combustion net assembly 120 can radiate heat energy, and the flashback barrier net assembly 130 is used to prevent flashback.

[0055] Specifically, a certain amount of combustible gas can be stored in the gas containing chamber 111, and the opening of the gas containing chamber 111 faces the combustion object assembly so that the combustible gas can flow to the combustion net assembly 120. The combustible gas burns on the combustion net assembly 120, and the temperature of the flame combustion is above 800°C, so that the combustion net assembly 120 is heated by the flame to form infrared heat radiation, so that the combustion net assembly 120 can radiate heat energy.

[0056] Furthermore, in order to prevent the flame on the combustion net assembly 120 from entering the gas receiving chamber 111 when flashback occurs, the present application further provides a flashback barrier net assembly 130 on the side of the combustion net assembly 120 facing the main body 110. When flashback occurs, the flashback barrier net 131 can play a certain blocking role on the flame, preventing the flame from entering the gas receiving chamber 111, thereby improving the safety of the burner 100.

[0057] Furthermore, the burner 100 is also provided with an ignition device, which is arranged on the main body 110. The ignition device can ignite the combustible gas flowing to the combustion network assembly 120, so that the burner 100 can operate normally and generate heat energy.

[0058] By arranging the combustion net assembly 120 and the flashback barrier net assembly 130 in the burner 100, the combustible gas can be burned on the combustion net assembly 120 to increase the temperature of the combustion net assembly 120, so that the combustion net assembly 120 can radiate heat energy, and the flashback barrier net assembly 130 prevents the flame from entering the gas receiving chamber 111, thereby improving the safety of the burner 100. Compared with existing products, the burner 100 proposed in this application has a simpler structure, lower manufacturing difficulty, reduced production cost, and higher safety and reliability.

[0059] In some embodiments, optionally, Figure 1 , Figure 2 and Figure 3 As shown, the burner 100 further includes: a supporting mesh assembly 140 installed between the combustion mesh assembly 120 and the flashback barrier mesh assembly 130 , and the supporting mesh assembly 140 is used to support the combustion mesh assembly 120 .

[0060] In this embodiment, the structure of the burner 100 is defined. The burner 100 also includes a support mesh assembly 140, which is used to support the combustion mesh assembly 120. It is understandable that if the combustion mesh assembly 120 is deformed, it will cause the flame on the surface of the combustion mesh assembly 120 to be unstable, thereby affecting the heating effect. In order to prevent the combustion mesh assembly 120 from deforming, the present application provides a support mesh assembly 140 in the burner 100, and the support mesh assembly 140 can support the combustion mesh assembly 120 to prevent the combustion mesh assembly 120 from deforming. The support mesh assembly 140 can be made of a material with high strength and high temperature resistance to improve the stability of the combustion mesh assembly 120.

[0061] By providing a support mesh assembly 140 for supporting the combustion mesh assembly 120 in the burner 100, deformation of the combustion mesh assembly 120 can be avoided, the stability of the combustion mesh assembly 120 can be improved, and the flame can be ensured to burn stably on the combustion mesh assembly 120.

[0062] In some embodiments, optionally, there is a gap between the flashback barrier mesh assembly 130 and the supporting mesh assembly 140 , and there is a gap between the supporting mesh assembly 140 and the combustion mesh assembly 120 .

[0063] In this embodiment, the support mesh assembly 140, the combustion mesh assembly 120 and the flashback barrier mesh assembly 130 are further defined. Specifically, there is a spacing between the support mesh assembly 140 and the combustion mesh assembly 120, and there is a spacing between the support mesh assembly 140 and the flashback barrier mesh assembly 130. In this way, it is equivalent to setting an air insulation layer between the support mesh assembly 140, the combustion mesh assembly 120 and the flashback barrier mesh assembly 130. Compared with the structure in which the support mesh assembly 140, the combustion mesh assembly 120 and the flashback barrier mesh assembly 130 are arranged in close proximity, the present application reduces the heat transfer between the support mesh assembly 140, the combustion mesh assembly 120 and the flashback barrier mesh assembly 130 by setting a spacing between the support mesh assembly 140 and the combustion mesh assembly 120 and between the support mesh assembly 140 and the flashback barrier mesh assembly 130, reduces the temperature of the flashback barrier mesh assembly 130, reduces the possibility of flashback, and improves the safety of the burner 100.

[0064] In some embodiments, optionally, the combustion net assembly 120 includes at least one combustion net 121, the support net assembly 140 includes at least one support net 141, the tempering barrier net assembly 130 includes at least one tempering barrier net 131, and the combustion net 121, the support net 141 and the tempering barrier net are made of metal material.

[0065] In this embodiment, the combustion net assembly 120, the support net assembly 140 and the tempering barrier net assembly 130 are further defined. Specifically, the combustion net assembly 120 includes at least one combustion net 121, the support net assembly 140 includes at least one support net 141, and the tempering barrier net assembly 130 includes at least one tempering barrier net 131. The combustion net 121, the support net 141 and the tempering barrier net are made of metal materials. By using metal materials to make the combustion net 121, the support net 141 and the tempering barrier net 131, on the one hand, the strength of the combustion net 121, the support net 141 and the tempering barrier net 131 can be improved. Compared with the combustion plate made of ceramic material, the combustion net 121, the support net 141 and the tempering barrier net 131 in the burner 100 proposed in the present application have higher strength. On the other hand, the mesh structure of the metal material is easy to process and easy to assemble, thereby reducing the difficulty of production.

[0066] In some embodiments, optionally, the mesh number of the combustion net 121 ranges from 40 mesh to 200 mesh.

[0067] In this embodiment, the mesh number range of the combustion net 121 is limited, specifically, the mesh number range of the combustion net 121 is 40 mesh to 200 mesh. It can be understood that the combustion net 121 is used to burn combustible gas to generate flames, which requires the flame to be stably distributed and burned on the combustion net 121. Therefore, the mesh number of the combustion net 121 cannot be too small, otherwise it will cause uneven flames. Therefore, the present application sets the mesh number of the combustion net 121 in the range of 40 mesh to 200 mesh to ensure that the flame on the combustion net 121 remains stable.

[0068] In some embodiments, optionally, the mesh number of the support net 141 ranges from 5 mesh to 40 mesh.

[0069] In this embodiment, the mesh number range of the support net 141 is limited, specifically, the mesh number range of the support net 141 is 5 meshes to 40 meshes. Since the support net 141 is arranged between the combustion net 121 and the gas accommodating chamber 111, the combustible gas needs to pass through the support net 141 to reach the combustion net 121, so the support net 141 needs to be set as a mesh structure with a large mesh size and a small mesh number. For this reason, the present application sets the mesh number of the support net 141 in the range of 5 meshes to 40 meshes to ensure that the combustible gas can smoothly pass through the support net 141.

[0070] In some embodiments, optionally, the mesh size of the tempering barrier net 131 ranges from 40 mesh to 200 mesh.

[0071] In this embodiment, the mesh number range of the tempering barrier net 131 is limited, specifically, the mesh number range of the tempering barrier net 131 is 40 mesh to 200 mesh. The tempering barrier net 131 is used to prevent tempering, so the tempering barrier net 131 needs to be set as a mesh structure with a larger mesh number. For this reason, the present application sets the mesh number of the tempering barrier net 131 in the range of 40 mesh to 200 mesh to improve the barrier effect of the tempering barrier net 131.

[0072] In some embodiments, optionally, the combustion mesh 121 has a thickness ranging from 0.1 mm to 0.5 mm.

[0073] In this embodiment, the thickness of the combustion net 121 is limited, specifically, the thickness of the combustion net 121 ranges from 0.1 mm to 0.5 mm. In this way, the problem of increased product volume due to excessive thickness of the combustion net 121 can be avoided while ensuring that the strength of the combustion net 121 meets the use requirements.

[0074] In some embodiments, optionally, the thickness of the support mesh 141 ranges from 0.2 mm to 2 mm.

[0075] In this embodiment, the thickness of the support net 141 is limited. Specifically, the thickness of the support net 141 ranges from 0.2 mm to 2 mm. It can be understood that the function of the support net 141 is to support the combustion net 121. Therefore, if the strength of the support net 141 is too low, the support effect of the support net 141 will be poor, which will cause the combustion net 121 to deform. Therefore, the present application limits the thickness of the support net 141 to a range of 0.2 mm to 2 mm to ensure that the strength of the support net 141 meets the use requirements. In addition, by making the support net 141 have a certain thickness, the support net 141 can also have a certain heat insulation effect.

[0076] In some embodiments, optionally, the tempering barrier mesh 131 has a thickness ranging from 0.1 mm to 0.5 mm.

[0077] In this embodiment, the thickness range of the tempering barrier net 131 is limited. Specifically, the thickness range of the tempering barrier net 131 is 0.1 mm to 0.5 mm. In this way, the problem of increased product volume due to excessive thickness of the tempering barrier net 131 can be avoided while ensuring that the strength of the tempering barrier net 131 meets the use requirements.

[0078] In some embodiments, optionally, Figure 1 , Figure 2 and Figure 3As shown, the main body 110 includes: a shell 112; a guide plate 113 connected to the shell 112, the shell 112 and the guide plate 113 together form a gas containing chamber 111, the guide plate 113 has a plurality of guide holes 114, and the guide holes 114 are used to discharge the combustible gas in the gas containing chamber 111 to the combustion network assembly 120.

[0079] In this embodiment, the structure of the main body 110 is defined. The main body 110 includes a shell 112 and a guide plate 113, wherein the guide plate 113 is connected to the shell 112, and the guide plate 113 and the shell 112 are combined to form a gas receiving chamber 111, and a certain amount of combustible gas can be contained in the gas receiving chamber 111. Furthermore, the guide plate 113 has a plurality of guide holes 114, and the combustible gas in the gas receiving chamber 111 can flow to the combustion net assembly 120 through the guide holes 114, so that the combustible gas can burn on the combustion net assembly 120, increase the temperature of the combustion net assembly 120, and then the combustion net assembly 120 can radiate heat energy. The guide holes 114 can guide the combustible gas. Since the combustible gas flows to the combustion mesh assembly 120 through the guide holes 114, the positions of the multiple guide holes 114 are rationally designed to allow the combustible gas to flow to the combustion mesh assembly 120 more evenly, thereby avoiding uneven flame distribution at various positions on the combustion mesh assembly 120 and maintaining uniform temperature at various positions of the combustion mesh assembly 120.

[0080] In some embodiments, optionally, Figure 2 As shown, a plurality of guide holes 114 are evenly distributed on the guide plate 113 .

[0081] In this embodiment, the setting positions of the plurality of guide holes 114 are limited, and specifically, the plurality of guide holes 114 are evenly distributed on the guide plate 113. Since the combustible gas flows to the combustion net assembly 120 through the guide holes 114, the combustible gas can flow to the combustion net assembly 120 more evenly by evenly distributing the plurality of guide holes 114 on the guide plate 113, thereby avoiding uneven distribution of flames at various positions on the combustion net assembly 120, and maintaining uniform temperatures at various positions of the combustion net assembly 120.

[0082] In some embodiments, optionally, Figure 1 and Figure 2 As shown, the burner 100 further includes: a gas pipe 150 connected to the shell 112 and communicated with the gas containing chamber 111 , and the gas pipe 150 is used to input combustible gas into the gas containing chamber 111 .

[0083] In this embodiment, the structure of the burner 100 is further defined, and the burner 100 also includes a gas pipe 150, which is used to input combustible gas into the gas containing chamber 111. Specifically, the gas pipe 150 is connected to the shell 112 and communicates with the gas containing chamber 111, and the combustible gas flows into the gas containing chamber 111 through the gas pipe 150. The gas pipe 150 extends into the gas containing chamber 111 to discharge the combustible gas from the central area of ​​the gas containing chamber 111 into the gas containing chamber 111, so that the concentration of the combustible gas at various places in the gas containing chamber 111 tends to be balanced, so that the combustible gas can flow to the combustion net assembly 120 more evenly, thereby improving the uniformity of the flame on the combustion net assembly 120.

[0084] In a possible embodiment, the burner 100 is mainly composed of a combustion surface (i.e., a combustion net assembly 120 and a support net assembly 140), an airflow distribution plate (i.e., a guide plate 113), a cavity (i.e., a gas containing cavity 111) and an ejector pipe (i.e., a gas pipe 150). The combustion surface is mainly composed of a flame combustion net (i.e., a combustion net assembly 120) and a heat insulation support net (i.e., a support net assembly 140), and the burner 100 further includes a flashback barrier net 131.

[0085] like Figure 5 As shown in the figure, the mixture of gas and air (combustible gas) enters the cavity from the ejector tube, and after being completely mixed in the cavity, it evenly enters the combustion surface from the air flow distribution plate. The flow direction of the combustible gas is as follows: Figure 5 As shown by the arrow in the middle. The flame burns on the flame combustion net on the combustion surface, forming hot air outflow. The flow direction of the hot air is as follows Figure 5 As shown, the heat energy is radiated. The heat insulation support net is used to support the flame burning net and play a role in partial heat insulation. The backfire barrier net 131 plays a role in preventing the flame from entering the cavity when it backfires. The temperature of the flame after combustion is above 800℃, which is used to heat the flame burning net and form heat radiation.

[0086] The flame burning net is on the outside of the heat insulating support net, the tempering barrier net 131 is on the inside of the heat insulating support net, and the heat insulating support net is between the tempering barrier net 131 and the flame burning net. After the gas flow passes through the tempering barrier net 131 and the heat insulating support net, it burns on the flame burning net.

[0087] The flame burning net is a mesh structure made of high temperature corrosion resistant metal, with a mesh number between 40 mesh and 200 mesh, and a mesh thickness between 0.1mm and 0.5mm. The heat insulation support net is also a mesh structure made of high temperature corrosion resistant metal, with a mesh number between 5 mesh and 40 mesh, and a mesh thickness between 0.2mm and 2mm. The tempering barrier net 131 is also a mesh structure made of high temperature corrosion resistant metal, with a mesh number between 40 mesh and 200 mesh, and a mesh thickness between 0.1mm and 0.5mm.

[0088] The mesh size of the heat insulation support net is larger than the mesh size of the flame combustion net. There is a certain distance between the heat insulation support net and the flame combustion net, which can be 0mm to 2mm. There is a certain distance between the tempering barrier net 131 and the heat insulation support net, which can be 0mm to 2mm.
