Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] The burner is widely used in the industry of gas oven and the like, and the working principle of the burner is usually to input fuel at a certain pressure into the burner from the flow guide port in the form of jet flow, to swirl the surrounding air and mix and ignite. However, in the prior art, since the fuel enters the accommodating cavity of the burner through the flow guide port, the fuel is prone to uneven distribution in the burner, which affects the user experience.

[0030] The fuel used in the burner is usually gas, and can also be liquid fuel with fluidity. The following embodiments of the present application will take the burner using gas as an example for introduction.

[0031] The present application first proposes a burner, as shown in Figures 1 to 6 , Figure 1 is a structural schematic view of an embodiment of the burner of the present application; Figure 2 is Figure 1 a top view schematic view of the embodiment; Figure 3 is Figure 1 a bottom view schematic view of the embodiment; Figure 4 is Figure 1 an exploded structural schematic view of the embodiment; Figure 5 is Figure 1 a sectional structural schematic view of the embodiment; Figure 6 is Figure 1Another schematic view of the cross-sectional structure of the embodiment. The combustor comprises a first shell 10, a combustion assembly 60, a flow distribution island 30, the first shell 10 forms a receiving cavity 05 with an opening 01 and a flow guide 02 communicating with the receiving cavity 05; the combustion assembly 60 covers the opening 01; the flow distribution island 30 is formed on the bottom wall of the receiving cavity 05, and the flow guide 02 is arranged on the side wall of the receiving cavity 05.

[0032] The combustible mixed fluid formed by the fuel and the combustion-supporting agent such as air can enter the receiving cavity 05 through the flow guide 02 and flow in the receiving cavity 05. Since the flow distribution island 30 is arranged on the bottom wall of the receiving cavity 05 and the flow guide 02 is arranged on the side wall of the receiving cavity 05, the fuel entering the receiving cavity 05 through the flow guide 02 can flow through the area where the flow distribution island 30 is located and be distributed by the flow distribution island 30, and then be uniformly distributed in the whole receiving cavity 05, thereby improving the uniformity of the distribution of the combustible mixed fluid in the receiving cavity 05.

[0033] The fuel can be combusted at the combustion assembly 60 and radiate heat outward through the combustion assembly 60.

[0034] The outer periphery of the combustion assembly 60 of the embodiment can be sealingly connected with the first shell 10, thereby reducing the risk of fuel leakage; the flow guide 02 of the embodiment is arranged on the side wall of the receiving cavity 05, and in one application scenario, as shown in the figure, the flow guide 02 can communicate with the opening 01; in other application scenarios (not shown in the figure), the flow guide can not communicate with the opening, but only communicate with the receiving cavity. Figure 4

[0035] The opening 01 of the receiving cavity 05 of the embodiment is arranged opposite to the bottom wall of the receiving cavity 05 and has the same size, that is, the opening 01 is an open opening; in other embodiments, the receiving cavity can also be provided with a top wall, and the opening is arranged on the top wall.

[0036] The receiving cavity 05 of the embodiment is conducive to further mixing and diffusion of the fuel and the combustion-supporting agent such as air.

[0037] ​The beneficial effects of the above-mentioned arrangement of the present embodiment are that the burner comprises the first shell 10, the combustion assembly 60, and the flow splitting island 30, has a simple structure, and can reduce the assembly difficulty; the first shell 10 forms the accommodating cavity 05 with the opening 01 and the drainage port 02 communicating with the accommodating cavity 05, the combustion assembly 60 is arranged on the opening 01, the combustible mixed fluid formed by the fuel and the combustion-supporting agent such as air enters the accommodating cavity 05 through the drainage port, and the combustion in the combustion assembly 60 and the outward radiation of heat are facilitated; the flow splitting island 30 is formed on the bottom wall of the accommodating cavity 05, the stability of the flow splitting island 30 is improved, the flow splitting effect is improved, and the flow splitting island 30 can improve the uniformity of the distribution of the combustible mixed fluid formed by the fuel and the combustion-supporting agent such as air in the accommodating cavity 05; the drainage port 02 is arranged on the side wall of the accommodating cavity 05, the fuel flowing out of the drainage port 02 flows through the area where the flow splitting island 30 is located, the flow splitting effect is improved, and the uniformity of the distribution of the combustible mixed fluid formed by the fuel and the combustion-supporting agent such as air is improved; further, the drainage port 02 is arranged on the side wall of the accommodating cavity 05, and the fuel input from the drainage port 02 can be in full contact with the combustion assembly 60 more quickly, and the uniformity of the contact of the combustible mixed fluid formed by the fuel and the combustion-supporting agent such as air with the combustion assembly 60 is improved. Therefore, the present embodiment can improve the uniformity of the distribution of the combustible mixed fluid formed by the fuel and the combustion-supporting agent such as air in the burner, improve the combustion effect, and improve the combustion performance of the burner.

[0038] Optionally, in order to further improve the uniformity of the distribution of the combustible mixed fluid formed by the fuel and the combustion-supporting agent such as air in the accommodating cavity 05, as shown in Figure 4 the flow splitting island 30 can be arranged on one side of the bottom wall close to the drainage port 02.

[0039] The flow splitting island 30 is arranged on one side of the bottom wall close to the drainage port 02, so that the combustible mixed fluid input from the drainage port 02 can be split when entering the accommodating cavity 05, the aggregation of the combustible mixed fluid in the middle area is reduced, and therefore the uniformity of the distribution of the combustible mixed fluid in the accommodating cavity 05 can be further improved.

[0040] Optionally, in order to further improve the uniformity of the distribution of the combustible mixed fluid in the accommodating cavity 05, the axial direction of the drainage port 02 can be perpendicular to the axial direction of the opening 01.

[0041] The axial direction of the flow port 02 is perpendicular to the axial direction of the opening 01, and the combustion assembly 60 covers the opening 01, that is, the axial direction of the flow port 02 is parallel to the extension direction of the combustion assembly 60, that is, the incident direction of the fuel input by the flow port 02 is parallel to the extension direction of the combustion assembly 60, so that the fuel input by the flow port 02 can be in contact with more areas of the combustion assembly 60 more quickly, and the uniformity of the contact between the fuel and the combustion assembly 60 can be improved, thereby improving the heat conduction efficiency of the heat generated by the fuel combustion to the combustion assembly 60, and further improving the heat radiation effect of the burner and the user experience.

[0042] Optionally, in order to further improve the uniformity of the distribution of the combustible mixed fluid in the accommodation cavity 05, the flow dividing island 30 comprises a first flow dividing island 31, and the bottom wall forms a first protruding portion 101 towards the accommodation cavity 05, and the first protruding portion 101 serves as the first flow dividing island 31; the first protruding portion 101 is located at a region of the bottom wall close to the flow port 02.

[0043] Specifically, the first flow dividing island 31 can be formed by the bottom wall forming the first protruding portion 101 towards the accommodation cavity 05, which can improve the structural stability of the first flow dividing island 31; and the first protruding portion 101 is formed by the bottom wall, which is simple in structure and can reduce the complexity of the production and assembly of the burner; the first protruding portion 101 is located at a region of the bottom wall close to the flow port 02, so as to improve the flow dividing effect on the combustible mixed fluid input from the flow port 02 and improve the uniformity of the distribution of the combustible mixed fluid in the accommodation cavity 05.

[0044] In other embodiments (not shown in the figure), the flow dividing island can be a porous flow dividing structure arranged on the bottom wall close to the flow port, and the specific form is not limited.

[0045] Optionally, in order to improve the flow dividing effect of the first protruding portion 101, the first protruding portion 101 can be provided with two inclined surfaces intersecting each other, and the intersection of the two inclined surfaces is arranged close to the flow port 02. Figure 4

[0046] Specifically, the intersection of the two inclined surfaces is arranged close to the flow port 02, that is, the intersection of the two inclined surfaces is arranged closer to the flow port 02 than other parts of the first protruding portion 101, and the two inclined surfaces each extend away from the flow port 02, so that the inclined surfaces can play a flow guiding effect and improve the flow dividing effect of the first protruding portion 101.

[0047] In some application scenarios, the first protruding portion 101 is triangular, and one vertex of the triangular shape is arranged towards the flow port 02, that is, the two inclined surfaces of the triangular shape forming the vertex serve as the two inclined surfaces intersecting each other of the first protruding portion 101.

[0048] ​In other embodiments, a plurality of first protrusions arranged at intervals may be formed on the bottom wall, facing the accommodating cavity, to further improve the uniformity of distribution of the combustible mixed fluid in the accommodating cavity. In some application scenarios, a plurality of first protrusions arranged at intervals are staggered on the bottom wall along a direction perpendicular to the axial direction of the drainage port to improve the diversion and diversion effect of the combustible mixed fluid in the accommodating cavity, and improve the uniformity of distribution of the combustible mixed fluid; in other application scenarios, the heights of the protrusions of the plurality of first protrusions arranged at intervals facing the accommodating cavity are different (for example, the height of the protrusions may be set to increase as the distance between the first protrusions and the drainage port increases), to improve the diversion and diversion effect of the combustible mixed fluid, and improve the uniformity of distribution of the combustible mixed fluid in the accommodating cavity.

[0049] In other embodiments, the position of the first protrusion may be adjusted according to product performance requirements, and is not specifically limited.

[0050] like Figure 4 As shown, in this embodiment, the two intersecting inclined surfaces are inclined planes. In other embodiments, the two intersecting inclined surfaces can also be inclined curved surfaces, for example, extending in a wave-like manner in the direction away from the drainage outlet, etc., without specific limitation.

[0051] Therefore, optionally, a first protrusion 101 is set to be spaced apart from the drainage port 02, and a second protrusion 102 is formed on the side of the bottom wall facing the accommodating cavity 05. The second protrusion 102 is connected to the side of the first protrusion 101 away from the drainage port 02, and the second protrusion 102 extends in a direction parallel to the bottom wall and is connected to the side wall of the accommodating cavity 05 where the drainage port 02 is not set.

[0052] Specifically, the combustible mixed fluid is input into the accommodating chamber 05 from the inlet 02 under a certain pressure, the first protrusion 101 is spaced apart from the inlet 02, and the second protrusion 102 is connected to the side of the first protrusion 101 away from the inlet 02, that is, the arrangement of the first protrusion 101 and the second protrusion 102 makes the cavity height of the accommodating chamber 05 in the direction perpendicular to the bottom wall smaller. Therefore, after the combustible mixed fluid flows into the accommodating chamber 05, the cross-sectional area of ​​the flow channel through which the combustible mixed fluid flows becomes smaller when it flows to the first protrusion 101 and the second protrusion 102, thereby increasing the flow velocity of the combustible mixed fluid at this location, thereby quickly directing the combustible mixed fluid input from the inlet 02 to the space on the side of the accommodating chamber 05 away from the inlet 02, thereby improving the distribution uniformity of the combustible mixed fluid in the accommodating chamber 05, and improving the uniformity of thermal radiation of the burner.

[0053] In some application scenarios, such as Figure 4As shown, the bottom wall is convex toward one side of the accommodating cavity 05 away from one end of the drainage port 02, forming a second convex portion 102, so that the second convex portion 102 is connected to the side wall of the accommodating cavity 05 not provided with the drainage port 02 in a direction parallel to the bottom wall, wherein the side of the second convex portion 102 close to the drainage port 02 is connected to the side of the first convex portion 101 away from the drainage port 02.

[0054] Optionally, the first convex portion 101 can be provided with a convex height in a direction perpendicular to the bottom wall, which is the same as the convex height of the second convex portion 102 in the direction perpendicular to the bottom wall, so that the structure is simple and convenient for production.

[0055] Optionally, in order to further improve the uniformity of the distribution of the combustible mixed fluid in the accommodating cavity 05, as shown, Figure 4 As shown, the flow splitting island 30 includes a second flow splitting island 32, and the second convex portion 102 is provided with a third convex portion 103 on the side thereof facing the accommodating cavity 05, and the third convex portion 103 is provided as the second flow splitting island 32 and is spaced apart from the side wall of the accommodating cavity 05 not provided with the drainage port 02.

[0056] The second convex portion 102 is provided with the third convex portion 103 on the side thereof facing the accommodating cavity 05, and the third convex portion 103 is provided as the second flow splitting island 32 and is spaced apart from the side wall of the accommodating cavity 05 not provided with the drainage port 02, which can further improve the flow splitting effect.

[0057] Optionally, as shown, Figure 4 As shown, the third convex portion 103 is provided with two intersecting inclined surfaces on the side thereof close to the drainage port 02, and the intersection of the two inclined surfaces is close to the drainage port 02. That is, the intersection of the two inclined surfaces is closer to the drainage port 02 than other parts of the third convex portion 103, and the two inclined surfaces each extend away from the drainage port 02. The inclined surfaces can play a flow guiding effect and can improve the flow splitting effect of the third convex portion 103.

[0058] Optionally, the first convex portion 101 can be provided with a convex height in a direction perpendicular to the bottom wall, which is lower than the convex height of the third convex portion 103 in the direction perpendicular to the bottom wall, so that the flow splitting of the combustible mixed fluid at different heights in the direction perpendicular to the bottom wall in the accommodating cavity 05 can be realized, and the flow splitting effect is further improved.

[0059] Optionally, the first convex portion 101, the second convex portion 102, and the third convex portion 103 are integrally formed with the bottom wall.

[0060] Optionally, in order to further improve the combustion completeness of the combustible mixed fluid, the combustion assembly 60 includes a flow splitting support plate 40 and a radiation member 20, the flow splitting support plate 40 forms a plurality of flow splitting holes and is arranged in the accommodating cavity 05 and fixedly connected to the first shell 10, and the radiation member 20 is arranged on the side of the flow splitting support plate 40 away from the bottom wall.

[0061] The combustion assembly 60 radiates heat outwardly through the radiating member 20. In an application scenario (not shown in the figure), the radiating member is provided with a plurality of openings in communication with the accommodating cavity and the external space. After the combustible mixed fluid is ignited, the radiating member can serve as a combustion net to realize the outward radiation of heat, for example, the radiating member is a metal combustion net. In another application scenario, the combustible mixed fluid in the accommodating cavity 05 is ignited, thereby heating the radiating member 20, and the radiating member 20 can radiate heat outwardly in the form of infrared radiation.

[0062] The shunt support plate 40 forms a plurality of shunt holes, which can further improve the shunting effect, so that the combustible mixed fluid in the accommodating cavity 05 can be more uniformly in contact with the radiating member 20, improving the uniformity of the radiating member 20 when heated, thereby improving the uniformity of the radiating member 20 radiating heat outwardly.

[0063] Optionally, in order to improve the structural stability of the radiating member 20, the shunt support plate 40 can be attached to the side of the radiating member 20 close to the first shell 10 to improve the support of the shunt support plate 40 to the radiating member 20.

[0064] Optionally, the shunt holes can include circular holes and / or square holes, and can also include diamond-shaped holes and the like, which are not limited in particular.

[0065] Optionally, in order to further improve the positional stability of the combustion assembly 60, the burner further comprises a fixing member 50, which is arranged on the side of the combustion assembly 60 away from the first shell 10 and is fixedly connected with the first shell 10 to fix the combustion assembly 60.

[0066] The fixing member 50 is arranged on the side of the combustion assembly 60 away from the first shell 10 and is fixedly connected with the first shell 10 to fix the combustion assembly 60.

[0067] For example, in some application scenarios (not shown in the figure), the fixing member can be fixedly connected with the first shell by rivets or the like to fix the combustion assembly between the first shell and the fixing member.

[0068] In order to improve the convenience of the combustible mixed fluid inputting into the accommodating cavity 05 through the drainage port 02, a suction channel in communication with the drainage port 02 can be provided.

[0069] Therefore, optionally, as Figure 4 , Figure 6As shown, the fixing member 50 comprises a first body part 51 and a first extension part 52, the first body part 51 forms the through hole 03, and the combustion assembly 60 is arranged at the through hole 03; the first extension part 52 is connected with the first body part 51, and the first extension part 52 forms the first flow channel 041; the first shell 10 comprises a second body part 11 and a second extension part 12, the second body part 11 forms the accommodating cavity 05; the second extension part 12 is connected with the second body part 11, and the second extension part 12 forms the second flow channel 042, which is in communication with the drainage port 02; the side wall of the first flow channel 041 and the side wall of the second flow channel 042 jointly form the ejecting flow channel 04, and the ejecting flow channel 04 is in communication with the drainage port 02.

[0070] Specifically, the side wall of the first flow channel 041 and the side wall of the second flow channel 042 jointly form the ejecting flow channel 04, that is, the first flow channel 041 and the second flow channel 042 are in communication, and because the second flow channel 042 is in communication with the drainage port 02, when the combustible mixed fluid enters the drainage port 02 through the ejecting flow channel 04, it can only enter the drainage port 02 through the second flow channel 042, that is, the cross-sectional area of the flow channel through which the combustible mixed fluid flows will become smaller, thereby increasing the flow rate of the combustible mixed fluid; and the gas in the first flow channel 041 is prevented from directly guiding to the side of the combustion assembly 60 away from the first shell and the inside of the combustion assembly 60.

[0071] Further, the first body part 51 forms the through hole 03, and the combustion assembly 60 is arranged at the through hole 03, thereby facilitating the combustion assembly 60 to radiate heat outward; the first extension part 52 forms the first flow channel 041, and the first extension part 52 is connected with the first body part 51; the second extension part 12 forms the second flow channel 042, and the second extension part 12 is connected with the second body part 11; the side wall of the first flow channel 041 and the side wall of the second flow channel 042 jointly form the ejecting flow channel 04, and the second extension part 12 is part of the first shell 10, so that the overall structure is simple, and the communication between the ejecting flow channel 04 and the drainage port 02 can be facilitated, thereby reducing the complexity of production and assembly.

[0072] Optionally, in order to improve the sufficiency of the contact between the combustible mixed fluid in the accommodating cavity 05 and the combustion assembly 60, the third protruding part 103 is provided with a first recessed part 104, the outer circumferential side of the first recessed part 104 is arranged in a spaced manner with the outer circumferential side of the third protruding part 103, and the first recessed part 104 protrudes towards the direction away from the accommodating cavity 05.

[0073] Specifically, in an application scenario, as shown in FIG. 6, the first shell 10 is arranged on the second shell 20, and the combustion assembly 60 is arranged in the accommodating cavity 05. Figure 4As shown, the first recessed portion 104 is located at the middle position of the third protruding portion 103, and the first recessed portion 104 protrudes towards the direction away from the accommodating cavity 05. When the combustible mixed fluid flows through the first recessed portion 104, the flow rate of the fluid can be reduced, thereby improving the distribution density of the combustible mixed fluid at this position, and further improving the heating effect of the combustion assembly 60 near the first recessed portion 104, and further improving the ability of the combustion assembly 60 to radiate heat outward.

[0074] Optionally, the first recessed portion 104 is arranged at the center position of the bottom wall to improve the distribution density of the combustible mixed fluid at the center position, thereby improving the distribution density of the combustible mixed fluid in the space near the accommodating cavity 05 centered on the first recessed portion 104, thereby improving the heating effect of the combustion assembly 60, and further improving the ability of the combustion assembly 60 to radiate heat outward.

[0075] Optionally, the radiation member 20 of the embodiment can be a metal combustion mesh, such as an iron-chromium-aluminum metal mesh, to improve the heat radiation effect of the radiation member 20, reduce production cost, and facilitate processing.

[0076] Optionally, the first shell 10, the fixing member 50, the flow splitting support plate 40, or the flow splitting island 30 can be an aluminum-plated or zinc-plated plate member, which is convenient to process, has good corrosion resistance, can improve the service life of the burner, and is convenient to process, such as a simple sealing processing method.
