[0034] In the related art, infrared burners generally conduct heat to the combustion surface by infrared radiation to heat food. In some existing technologies, the combustion surface of the infrared burner adopts a multi-layer metal mesh. In the actual production process, the fixed installation operation of the metal mesh is inconvenient, and the metal mesh is prone to flexible deformation during processing and after heating. The overall structure of the combustion surface is unstable, which affects the heating effect.

[0035] Reference below Figure 1-Figure 4 A burner 1 according to an embodiment of the present invention is described.

[0036] like Figure 1-Figure 4 As shown, the burner 1 according to the utility model includes: a main body 10, a support plate 20 and a combustion net assembly 30. The main body 10 is formed with a gas accommodating chamber 10a and an open port 10b connected to the gas accommodating chamber 10a, and the gas accommodating chamber 10a is suitable for accommodating combustible gas; the support plate 20 is arranged on the main body 10 and covers the open port 10b, and the surface of the support plate 20 away from the open port 10b is provided with a support protrusion 21 and a first connecting portion 22; the surface of the combustion net assembly 30 facing the support plate 20 is suitable for abutting against the support protrusion 21, and the combustion net assembly 30 is provided with a second connecting portion 31, and the second connecting portion 31 is suitable for connecting with the first connecting portion 22. Specifically, after the combustion net assembly 30 is fixed to the support plate 20, the support plate 20 is connected to the main body 10 to connect the combustion net assembly 30 to the main body 10.

[0037] In some embodiments, the combustion mesh assembly 30 is composed of multiple layers of stacked metal meshes. Since the metal mesh is a flexible structure, it is easy to undergo flexible deformation during processing and after heating. Therefore, a support protrusion 21 is provided on the support plate 20 to tighten the combustion mesh assembly 30 after the combustion mesh assembly 30 is connected to the support plate 20, so that the combustion mesh assembly 30 is pre-deformed, thereby reducing the deformation of the combustion mesh assembly 30 during processing and heating, and improving the structural stability of the combustion mesh assembly 30.

[0038] In some embodiments, the combustion mesh assembly 30 and the support plate 20 are fixedly matched by connecting the second connecting portion 31 with the first connecting portion 22. After the combustion mesh assembly 30 is connected to the support plate 20, the support protrusion 21 on the support plate 20 abuts against the combustion mesh assembly 30 to support the combustion mesh assembly 30.

[0039] According to the burner 1 of the utility model, a supporting protrusion 21 is set on the supporting plate 20 to support the combustion mesh assembly 30 after the supporting plate 20 is connected to the combustion mesh assembly 30, so as to realize the pre-deformation of the combustion mesh assembly 30, thereby reducing the deformation amount of the combustion mesh assembly 30 after heating, improving the structural stability of the combustion mesh assembly 30, and ensuring the heating effect of the combustion mesh assembly 30.

[0040] According to some embodiments of the present invention, Figure 4 As shown, the first connection portion 22 and the second connection portion 31 are welded and / or connected by a fixing member (not shown). Specifically, the first connection portion 22 and the second connection portion 31 can be directly connected by welding, or can be fixed and matched by fixing members such as bolts and rivets, and the design can be based on actual needs, which is not limited here.

[0041] According to some embodiments of the present invention, Figure 2As shown, the support plate 20 includes a plate body, and one side surface of the plate body in the thickness direction is constructed as a first surface 201, and the first surface 201 is arranged away from the opening 10b; wherein a portion of the first surface 201 is protrudingly provided with a support protrusion 21 in the thickness direction; a portion of the surface of the first surface 201 surrounding the support protrusion 21 is constructed as a first connecting portion 22. Specifically, the plate body can be a circular, elliptical plate structure, or a polygonal plate structure, and can be designed according to actual needs. To ensure the supporting effect of the support protrusion 21 on the combustion mesh assembly 30, in some embodiments, the support protrusion 21 is located in the middle part of the support plate 20, and the edge of the support plate 20 is provided with a first connecting portion 22, and the second connecting portion 31 can also be provided at the edge of the combustion mesh assembly 30. When the first connecting portion 22 is fixedly connected to the second connecting portion 31, the edge of the support plate 20 is connected to the edge of the combustion mesh assembly 30, and the support protrusion 21 is stopped at the middle part of the combustion mesh assembly 30 to play a better supporting role, so that the combustion mesh assembly 30 can be deformed as much as possible, the pre-deformation of the combustion mesh assembly 30 is increased, and the deformation of the combustion mesh assembly 30 after heating is greatly reduced.

[0042] In some embodiments, the support protrusion 21 protrudes from the first surface 201 and has a dimension d in the thickness direction. It can be understood that in order to avoid excessive supporting force of the support protrusion 21 on the combustion mesh assembly 30, so as to avoid the support protrusion 21 damaging the combustion mesh assembly 30, the support protrusion 21 should not protrude too much from the first surface 201, and in order to ensure the tightening effect of the combustion mesh assembly 30, the support protrusion 21 should not protrude too little from the first surface 201. Therefore, the dimension of the support protrusion 21 protruding from the first surface 201 satisfies 2≤d≤15mm.

[0043] According to some embodiments of the present invention, Figure 2 As shown, the first connection portion 22 is located at at least one side edge of the first surface 201. Figure 4 As shown, the first connecting portion 22 includes a first extension plate 221, a bending plate 222 and a second extension plate 223, one end of the first extension plate 221 is connected to the support protrusion 21; the bending plate 222 extends in the thickness direction, one end of the bending plate 222 is connected to the other end of the first extension plate 221; the second extension plate 223 is spaced and opposite to at least part of the first extension plate 221 in the thickness direction, one end of the second extension plate 223 is connected to the other end of the bending plate 222, and the second extension plate 223, the bending plate 222 and the first extension plate 221 jointly define a groove body 22a suitable for accommodating the second connecting portion 31. Specifically, after the second connecting portion 31 is placed in the groove body 22a, the first connecting portion 22 can clamp the second connecting portion 31, and under the support of the support protrusion 21, the combustion net assembly 30 is tightened to achieve pre-deformation.

[0044] In some embodiments, before the first connection part 22 is connected and matched with the second connection part 31, the first connection part 22 is a flat plate, and the second connection part 31 is in contact with part of the first connection part 22 and has a certain distance from the edge of the first connection part 22. At this time, the first connection part 22 that is not in contact with the second connection part 31 can be punched and bent to form the above-mentioned groove body 22a. The part of the first connection part 22 that is in contact with the second connection part 31 is the first extension plate 221, and the part of the first connection part 22 that is bent is the bent plate 222. The part of the first connection part 22 that is opposite to the first extension plate 221 after punching and bending is the second extension plate 223. At this time, the second extension plate 223 can be pressed toward the first extension plate 221 to achieve the pressing of the second connection part 31. The first connection part 22 and the second connection part 31 can be connected by welding and / or by a fixing member. Forming the groove body 22a by the above-mentioned punching and bending method can simplify the production process and reduce the production cost.

[0045] According to some embodiments of the utility model, a first through hole is provided on the first extension plate 221, a second through hole is provided on the second connecting portion 31, and a third through hole is provided on the second extension plate 223. The fixing member passes through the first through hole, the second through hole and the third through hole to fix the first extension plate 221, the second connecting portion 31 and the second extension plate 223 in the thickness direction. In some embodiments, the fixing member is constructed as a screw or a rivet, and the first connecting portion 22 is connected to the second connecting portion 31 by means of threaded connection or rivet connection. The structure is simple and reliable, and the feasibility is high.

[0046] According to some embodiments of the utility model, a support protrusion 21 is provided on the radially inner side of the first surface 201, and the first connecting portion 22 is arranged around the outer periphery of the support protrusion 21. Here, the plate body can be a circular plate body structure. To ensure the supporting effect of the support protrusion 21 on the combustion mesh assembly 30, the support protrusion 21 is located on the radially inner side of the first surface 201, and the first connecting portion 22 is arranged around the outer periphery of the support protrusion 21. When the first connecting portion 22 is fixedly connected to the second connecting portion 31, the first connecting portion 22 located at the edge of the support protrusion 21 is connected to the second connecting portion 31 of the combustion mesh assembly 30, and the support protrusion 21 is stopped at the middle part of the combustion mesh assembly 30 to provide a better supporting effect.

[0047] According to some embodiments of the present invention, Figure 2As shown, a plurality of first connection parts 22 are provided on the edge of the first surface 201, and a support protrusion 21 is provided on the inner side of the plurality of first connection parts 22. Here, the plate body can be a rectangular plate body structure, and the four edges of the plate body are provided with first connection parts 22. The support protrusion 21 is located in the middle part of the support plate 20. When the first connection part 22 is fixedly connected with the second connection part 31, the edge of the support plate 20 is connected to the edge of the combustion mesh assembly 30, and the support protrusion 21 is stopped at the middle part of the combustion mesh assembly 30 to provide better support.

[0048] According to some embodiments of the utility model, the edge of the open mouth 10b defined by the main body 10 is provided with a first fixing portion, and the support plate 20 is provided with a second fixing portion, and the second fixing portion is suitable for being fixedly matched with the first fixing portion. After the combustion mesh assembly 30 is fixed to the support plate 20, the support plate 20 is then connected to the main body 10 to connect the combustion mesh assembly 30 with the main body 10, so as to facilitate the installation of the combustion mesh assembly 30, so that the combustion mesh assembly 30 can be kept in a taut state during the installation process, thereby avoiding deformation of the combustion mesh assembly 30 during the installation process.

[0049] According to some embodiments of the present invention, a plurality of guide holes are formed on the support plate 20 and are arranged through the thickness direction, and the support plate 20 is suitable for diverting the combustible gas; the combustion net assembly 30 is constructed as a mesh structure so as to enable the combustible gas to burn on the surface of the combustion net assembly 30, and the combustion net assembly 30 is suitable for being arranged toward the outside to radiate heat energy to the outside; Figure 3 As shown, the combustion net assembly 30 includes a flashback barrier net 301, a combustion support net 302 and a combustion reaction net 303. The flashback barrier net 301 is located on the side of the combustion net assembly 30 facing the support plate 20, and the flashback barrier net 301 is used to prevent the flame on the combustion net assembly 30 from entering the gas containing chamber 10a; the combustion support net 302 is arranged on the side of the flashback barrier net 301 away from the support plate 20; the combustion reaction net 303 is arranged on the side of the combustion support net 302 away from the flashback barrier net 301, and the combustion reaction net 303 is suitable for a combustion reaction of combustible gas to occur, and the combustion support net 302 is located between the flashback barrier net 301 and the combustion reaction net 303 to support the combustion reaction net 303.

[0050] Specifically, the burner 1 proposed in the utility model can be used in a cooking utensil. When the burner 1 is in operation, it can heat the inside of the cooking utensil to heat and cook the food. A certain amount of combustible gas can be stored in the gas containing chamber 10a, and the open mouth 10b of the gas containing chamber 10a faces the combustion net assembly 30 so that the combustible gas can flow to the combustion net assembly 30. The combustible gas burns on the combustion net assembly 30, and the temperature of the flame combustion is above 800°C, so that the combustion net assembly 30 is heated by the flame, forming infrared heat radiation, so that the combustion net assembly 30 can radiate heat energy.

[0051] In order to prevent the flame on the combustion net assembly 30 from entering the gas containing chamber 10a when it flashes back, a flashback barrier net 301 is provided on the side of the combustion net assembly 30 facing the main body 10. When flashback occurs, the flashback barrier net 301 can play a certain blocking role on the flame, preventing the flame from entering the gas containing chamber 10a, thereby improving the safety of the burner 1.

[0052] The burner 1 is also provided with an ignition device, which is arranged on the main body 10. The ignition device can ignite the combustible gas flowing to the combustion reaction network 303, so that the burner 1 can operate normally and generate heat energy.

[0053] By arranging a combustion reaction net 303 and a flashback barrier net 301 in the burner 1, the combustible gas can burn on the combustion reaction net 303 to increase the temperature of the combustion reaction net 303, so that the combustion reaction net 303 can radiate heat energy, and the flashback barrier net 301 can prevent the flame from entering the gas containing cavity 10a, thereby improving the safety of the burner 1.

[0054] The combustion support net 302 is installed between the combustion net assembly 30 and the tempering barrier net 301 to support the combustion net assembly 30. It is understandable that if the combustion reaction net 303 is deformed, the flame on the surface of the combustion reaction net 303 will be unstable, thereby affecting the heating effect. In order to prevent the combustion reaction net 303 from deforming, the combustion support net 302 is provided to support the combustion reaction net 303 to prevent the combustion reaction net 303 from deforming. The combustion support net 302 can be made of a material with high strength and high temperature resistance to improve the stability of the combustion reaction net 303, thereby ensuring that the flame can burn stably on the combustion reaction net 303.

[0055] The cooking device according to the present invention is briefly described below.

[0056] The cooking utensil according to the utility model comprises the burner 1 described in any one of the above embodiments. Since the cooking utensil according to the utility model is provided with the burner 1 described in the above embodiments, the cooking utensil is reliable to use.

[0057] In summary, according to the burner 1 of the utility model, the support protrusion 21 is set on the support plate 20, which can tighten the combustion mesh assembly 30, make the combustion mesh assembly 30 pre-deformed, reduce the deformation of the combustion mesh assembly 30 after heating, improve the structural stability of the combustion mesh assembly 30, and ensure the heating effect of the combustion mesh assembly 30.
