[0037] The burner 100 and cooking equipment according to the embodiments of the present invention will be described below with reference to the drawings.

[0038] As Figure 1 、 Figure 3As shown in the figure, the burner 100 according to an embodiment of the present invention includes: a gas distribution plate 10, a first flow equalizing plate 20, a furnace body 30, and a second flow equalizing plate 40. Among them, a gas distribution cavity 17 is defined in the gas distribution plate 10, and the gas distribution plate 10 has an air inlet 11 and an air outlet 12 located at the top. The first flow equalizing plate 20 is covered in the gas distribution cavity 17 and is located above the air inlet 11. The furnace body 30 is connected to the gas distribution plate 10 and is provided on the air outlet 12. The second flow equalizing plate 40 is provided in the furnace body 30, and a flow equalizing cavity 34 is formed between the first flow equalizing plate 20 and the second flow equalizing plate 40. A combustion cavity 35 is formed in the furnace body 30 above the second flow equalizing plate 40.

[0039] It can be understood that the gas enters the gas distribution plate 10 from the air inlet 11, passes upward through the gas distribution cavity 17, then passes through the first flow equalizing plate 20 and enters the furnace body 30 from the air outlet 12. After the gas enters the furnace body 30, it flows through the second flow equalizing plate 40 from the flow equalizing cavity 34 and flows to the combustion cavity 35 for combustion. The gas distribution plate 10 is located below the furnace body 30, and the gas distribution cavity 17, the flow equalizing cavity 34, and the combustion cavity 35 are arranged in sequence from bottom to top. Moreover, the gas distribution cavity 17 and the flow equalizing cavity 34 are separated by the first flow equalizing plate 20, and the flow equalizing cavity 34 and the combustion cavity 35 are separated by the second flow equalizing plate 40, which can ensure that the gas can flow through the first flow equalizing plate 20 and the second flow equalizing plate 40 in sequence, improve the uniformity of the gas when flowing to the combustion cavity 35, and improve the uniformity of combustion at various places in the combustion cavity 35.

[0040] Therefore, the first flow equalizing plate 20 is covered in the gas distribution cavity 17, that is, the first flow equalizing plate 20 is provided in the gas distribution plate 10, and the second flow equalizing plate 40 is provided in the furnace body 30. Since the gas distribution plate 10 is located below the furnace body 30, the first flow equalizing plate 20 can be kept below the second flow equalizing plate 40, thereby improving the stability of the relative positions of the first flow equalizing plate 20 and the second flow equalizing plate 40, and improving the stability of the gas flowing through the gas distribution cavity 17, the flow equalizing cavity 34, and the combustion cavity 35 in sequence.

[0041] Preferably, the gas distribution plate 10 and the furnace body 30 are long strips extending horizontally.

[0042] In some embodiments, as Figure 1 , Figure 2 , Figure 5 and Figure 6 shown, the gas distribution plate 10 is provided with a flow dividing rib 13 in the gas distribution cavity 17, and the first flow equalizing plate 20 is located above the flow dividing rib 13. Among them, the lower surface of the first flow equalizing plate 20 abuts against the flow dividing rib 13, or the lower end of the furnace body 30 abuts against the upper surface of the first flow equalizing plate 20, or while the lower surface of the first flow equalizing plate 20 abuts against the flow dividing rib 13, the lower end of the furnace body 30 abuts against the upper surface of the first flow equalizing plate 20.

[0043] It can be understood that when the lower surface of the first flow equalizing plate 20 abuts against the flow dividing rib 13, the flow dividing rib 13 can provide upward support for the first flow equalizing plate 20. When the lower end of the furnace body 30 abuts against the upper surface of the first flow equalizing plate 20, the furnace body 30 can press the first flow equalizing plate 20 downward against the upper part of the flow dividing rib 13.

[0044] Thereby, the position stability of the first flow equalizing plate 20 covering the gas distribution cavity 17 can be improved, the vertical or horizontal movement of the first flow equalizing plate 20 can be reduced or avoided, the stability of the gas passing through the first flow equalizing plate 20 can be improved, and the flow equalizing effect of the first flow equalizing plate 20 on the gas can be ensured.

[0045] Preferably, as Figure 1 , Figure 5 shown, the first flow equalizing plate 20 is in close contact with the inner wall of the gas distribution disc 10 in the circumferential direction, so as to reduce or avoid the gas in the gas distribution cavity 17 flowing from the gap between the first flow equalizing plate 20 and the inner wall of the gas distribution disc 10 to the flow equalizing cavity 34. Ensure that all the gas in the gas distribution cavity 17 can flow through the first flow equalizing plate 20 to the flow equalizing cavity 34, so as to ensure the flow equalizing effect of the flow equalizing cavity 34 on the gas.

[0046] In some embodiments, as Figure 1 , Figure 2 shown, the gas distribution disc 10 includes: a bottom plate 14 and an annular plate 15. An air inlet 11 is provided on the bottom plate 14. The annular plate 15 is annular and connected to the edge of the bottom plate 14. The annular plate 15 and the bottom plate 14 enclose the gas distribution cavity 17. A stepped surface 16 is formed at the upper end of the annular plate 15, and the lower end of the furnace body 30 is fitted on the stepped surface 16.

[0047] Thereby, the stepped surface 16 can provide support for the furnace body 30 and improve the stability of the furnace body 30 on the gas distribution disc 10. And the furnace body 30 is fitted with the stepped surface 16, and the stepped surface 16 is annular along the annular plate 15, so that the stepped surface 16 can be fitted with the furnace body 30 in the circumferential direction and improve the position stability of the furnace body 30.

[0048] Preferably, the circumferential edge of the first flow equalizing plate 20 abuts against the annular plate 15 in the horizontal direction, so as to reduce or avoid the gas passing through the gap between the first flow equalizing plate 20 and the annular plate 15. At the same time, the annular plate 15 can limit the position of the first flow equalizing plate 20 in the horizontal direction, reduce or avoid the displacement of the first flow equalizing plate 20 in the horizontal direction, and improve the position stability of the first flow equalizing plate 20 in the gas distribution cavity 17.

[0049] Furthermore, the stepped surface 16 includes a transverse annular surface and a vertical annular surface. The transverse annular surface is annular and extends horizontally, and the vertical annular surface is annular and extends vertically. The vertical annular surface connects the outer edge of the transverse annular surface. The lower end of the furnace body 30 is located on the transverse annular surface, so that the transverse annular surface can provide support for the furnace body 30, and at least part of the edge of the first flow equalizing plate 20 is clamped between the transverse annular surface and the bottom surface of the furnace body 30, which can improve the position stability of the first flow equalizing plate 20 and reduce or avoid the displacement of the first flow equalizing plate 20 in the vertical or horizontal direction.

[0050] Meanwhile, the vertical annular surface surrounds the outside of the lower end of the furnace body 30, so that the vertical annular surface can limit the horizontal position of the furnace body 30 relative to the gas distribution plate 10, thereby reducing or avoiding the horizontal displacement of the furnace body 30 relative to the gas distribution plate 10 and improving the relative position stability between the furnace body 30 and the gas distribution plate 10. And the vertical annular surface has a guiding effect on the installation of the furnace body 30 on the gas distribution plate 10, which is convenient for installing the furnace body 30 to the correct position on the gas distribution plate 10 and reducing the installation difficulty of installing the furnace body 30 to the gas distribution plate 10.

[0051] A retaining rib 31 is provided on the outer periphery of the furnace body 30, and the retaining rib 31 abuts against the top surface of the gas distribution plate 10. Thus, the position of the furnace body 30 relative to the gas distribution plate 10 in the vertical direction can be limited through the retaining rib 31, and the weight of the furnace body 30 is respectively borne by the top surface of the gas distribution plate 10 and the transverse annular surface at the retaining rib 31 and the lower end of the furnace body 30, so that the gas distribution plate 10 can disperse and bear the weight of the furnace body 30 and improve the structural stability of the gas distribution plate 10.

[0052] When at least part of the first flow equalizing plate 20 is clamped between the transverse annular surface and the bottom surface of the furnace body 30, part of the weight of the furnace body 30 is borne by the top surface of the gas distribution plate 10 at the retaining rib 31, which can reduce the pressure exerted on the first flow equalizing plate 20 by the furnace body 30, thereby reducing or avoiding the first flow equalizing plate 20 being crushed by the furnace body 30, improving the structural stability of the first flow equalizing plate 20, and the reliability of the limiting effect of the furnace body 30 on the first flow equalizing plate 20.

[0053] In addition, the furnace body 30 and the gas distribution plate 10 cooperate to form a labyrinth seal at the stepped surface 16, which can improve the sealing performance between the furnace body 30 and the gas distribution plate 10 and reduce or avoid air leakage in the gap between the furnace body 30 and the gas distribution plate 10.

[0054] In some embodiments, as Figure 1 、 Figure 2 and Figure 4 shown, positioning ribs 32 are provided on the inner wall of the furnace body 30, and the second flow equalizing plate 40 is lapped on the positioning ribs 32. Thus, the positioning ribs 32 can limit the vertical position of the second flow equalizing plate 40 in the furnace body 30, and at the same time the positioning ribs 32 provide upward support for the second flow equalizing plate 40, improving the setting stability of the second flow equalizing plate 40 in the furnace body 30.

[0055] In addition, by positioning the convex ribs 32 to define the installation position of the second flow equalizing plate 40 within the furnace body 30, the second flow equalizing plate 40 can be installed within the furnace body 30 simply by placing it on the positioning convex ribs 32, which can reduce the installation difficulty of the second flow equalizing plate 40 within the furnace body 30.

[0056] In this application, the number and length of the positioning convex ribs 32 are not limited. For example, in Figure 4 the example, the positioning convex ribs 32 extend in the horizontal direction.

[0057] Preferably, the positioning convex ribs 32 are arranged at equal intervals along the inner wall of the furnace body 30, or the positioning convex ribs 32 are symmetrically distributed axially or mirror-symmetrically along the circumference of the second flow equalizing plate 40, so as to improve the stability of the positioning convex ribs 32 in supporting the second flow equalizing plate 40.

[0058] In some embodiments, as Figure 1 , Figure 4 shown, an igniter fixing part 33 is provided within the furnace body 30, and the igniter fixing part 33 is located below the second flow equalizing plate 40. The burner 100 further includes: an igniter 50, the igniter 50 is provided on the igniter fixing part 33 and passes through the second flow equalizing plate 40, and the ignition end 51 of the igniter 50 is located within the combustion chamber 35.

[0059] It can be understood that the igniter fixing part 33 is located within the furnace body 30, and the furnace body 30 is located above the first flow equalizing plate 20, that is, the igniter fixing part 33 is located above the first flow equalizing plate 20.

[0060] Thus, the igniter fixing part 33 is located above the first flow equalizing plate 20, enabling the igniter fixing part 33 to form a block above the first flow equalizing plate 20, while the igniter 50 is located above the second flow equalizing plate 40 at the ignition end 51, enabling the igniter 50 to form a block above the second flow equalizing plate 40. When the furnace body 30 shakes and causes the first flow equalizing plate 20 and the second flow equalizing plate 40 to shift upward, the igniter fixing part 33 can block the upward shift of the first flow equalizing plate 20, and the igniter 50 can block the upward shift of the second flow equalizing plate 40, thereby improving the position stability of the first flow equalizing plate 20 and the second flow equalizing plate 40.

[0061] Meanwhile, the igniter fixing part 33 is located between the first flow equalizing plate 20 and the second flow equalizing plate 40, functioning to separate the first flow equalizing plate 20 and the second flow equalizing plate 40, reducing or avoiding collisions between the first flow equalizing plate 20 and the second flow equalizing plate 40.

[0062] Further, the igniter fixing part 33 includes an igniter fixing plate 331 connected to the inner wall of the furnace body 30. The igniter fixing plate 331 is provided with a positioning hole 332 and a fixing hole 333. The igniter 50 passes through the positioning hole 332 and is detachably connected to the fixing hole 333. Thus, the igniter fixing plate 331 is used to increase the contact area between the igniter 50 and the igniter fixing part 33, and at the same time provide support for the igniter 50 to improve the stability of the igniter 50 disposed in the igniter fixing part 33. The positioning hole 332 is used to limit the setting position of the igniter 50 in the igniter fixing part 33, and the igniter 50 is fixed to the igniter fixing plate 331 through the fixing hole 333, thereby improving the firmness of the igniter 50 fixed to the igniter fixing part 33.

[0063] In addition, the ignition end 51 and the igniter fixing plate 331 are arranged staggeredly in the horizontal direction. Thus, it is possible to reduce or avoid the influence of the igniter 50 on the igniter fixing plate 331 when the igniter 50 ignites at the ignition end 51, and it is also possible to reduce or avoid the spatial blockage of the igniter fixing plate 331 on the ignition operation of the ignition end 51, improving the reliability of ignition at the ignition end 51.

[0064] In this application, the method of realizing the detachable connection of the igniter 50 to the fixing hole 333 is not limited. For example, the igniter 50 is detachably connected to the fixing hole 333 by a screw.

[0065] It should be noted that during the installation of the igniter 50 and the second flow equalizing plate 40, after the igniter 50 is installed on the igniter fixing part 33, the second flow equalizing plate 40 is then installed into the furnace body 30, so as to avoid the second flow equalizing plate 40 blocking the installation of the igniter 50 on the igniter fixing part 33 and improving the reliability of the igniter 50 installed on the igniter fixing part 33.

[0066] In some embodiments, as Figure 1 、 Figure 3 shown, the burner 100 further includes: a gas mixing tank 60. The gas mixing tank 60 further includes a gas supply port 61. The gas supply port 61 communicates with the air inlet 11. The gas mixing tank 60 is provided with a first fixing plate 62 surrounding the gas supply port 61. Among them, the gas distribution plate 10 includes a second fixing plate 18 surrounding the air inlet 11. The second fixing plate 18 is connected to the first fixing plate 62.

[0067] Thus, a relatively large contact area can be formed between the first fixing plate 62 and the second fixing plate 18, thereby improving the connection stability between the first fixing plate 62 and the second fixing plate 18, and further improving the connection stability between the gas supply port 61 and the air inlet 11, so that the gas provided by the gas mixing tank 60 can stably enter the gas distribution plate 10.

[0068] Preferably, the first fixing plate 62 is integrally formed on the gas mixing tank 60, and the second fixing plate 18 is integrally formed on the gas distribution plate 10.

[0069] In this application, there is no limitation on the way to connect the first fixing plate 62 and the second fixing plate 18. For example, the first fixing plate 62 and the second fixing plate 18 are fixedly connected by screw cooperation.

[0070] Preferably, 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 a mixed gas, and the mixed gas passes through the air supply port 61 and enters the gas distribution cavity 17 from the air inlet 11, and then passes through the first flow equalizing plate 20, the flow equalizing cavity 34 and the second flow equalizing plate 40 in sequence and then burns in the combustion cavity 35.

[0071] Furthermore, the gas mixing tank 60 further includes a first connecting pipe (not shown in the figure). One end of the first connecting pipe facing the air inlet 11 forms the air supply port 61, and the first fixing plate 62 is arranged at one end of the first connecting pipe facing the air inlet 11.

[0072] Or, as Figure 1 、 Figure 3 shown, the gas distribution plate 10 includes a second connecting pipe 19. One end of the second connecting pipe 19 facing the air supply port 61 forms the air inlet 11, and the second fixing plate 18 is arranged at one end of the second connecting pipe 19 facing the air inlet 11.

[0073] Or, while the gas mixing tank 60 further includes a first connecting pipe, the gas distribution plate 10 is also provided with a second connecting pipe 19, and the first connecting pipe is docked and communicated with the second connecting pipe 19.

[0074] Thus, the first connecting pipe and the second connecting pipe 19 can form a channel for gas flow to limit the gas flow direction, make the gas flow direction from the air supply port 61 to the air inlet 11 more unified, reduce or avoid the gas from flowing back into the gas mixing tank 60, and improve the flow efficiency of the gas flowing into the gas distribution cavity 17.

[0075] Preferably, the first connecting pipe is integrally formed on the gas mixing tank 60, and the second connecting pipe 19 is integrally formed on the gas distribution plate 10.

[0076] In this application, there is no limitation on the structure of the first connecting pipe or the second connecting pipe 19. For example, the first connecting pipe or the second connecting pipe 19 is set as a straight pipe. Or, the first connecting pipe or the second connecting pipe 19 is set as a gradually expanding pipe and expands gradually in the direction towards the air inlet 11.

[0077] In some embodiments, a wire mesh is provided on the upper surface of the second flow equalizing plate 40, and the wire mesh is welded to the second flow equalizing plate 40.

[0078] It can be understood that the wire mesh has a relatively high thermal conductivity. The wire mesh is located on the upper surface of the second flow equalizing plate 40, that is, the wire mesh is located inside the combustion chamber 35. When combustion occurs in the combustion chamber 35, the wire mesh can conduct heat to make the temperature at the upper surface of the second flow equalizing plate 40 more uniform, thereby improving the combustion uniformity in the combustion chamber 35, facilitating the full combustion of the gas in the combustion chamber 35, and improving the combustion efficiency in the combustion chamber 35.

[0079] In this application, the welding method of the wire mesh on the upper surface of the second flow equalizing plate 40 is not limited. For example, the wire mesh is connected to the upper surface of the wire mesh by spot welding.

[0080] The cooking device according to an embodiment of the present utility model includes the burner 100 of the above embodiment.
