[0054] See also Figure 1 , Figure 2 and Figure 3 The present invention proposes a burner, comprising: a gas distribution plate 20, wherein the gas distribution plate 20 is provided with a plurality of first guide holes 24 at intervals along its circumference; a first fire cover 30, which is covered on the gas distribution plate 20, wherein the first fire cover 30 and the gas distribution plate 20 enclose a plurality of first combustion chambers 313, wherein the first fire cover 30 is provided with a plurality of first fire holes 311 at positions corresponding to each of the first combustion chambers 313, wherein the plurality of first fire holes 311 are connected to the first combustion chambers 313 at corresponding positions; and each of the first combustion chambers 313 corresponds to the position of at least one of the first guide holes 24, and are connected to each other.

[0055] See also Figure 4 , Figure 5 and Figure 6 , the gas distribution plate 20 is used to connect with other functional components of the burner, and serves as a supporting mechanism for supporting and connecting the first fire cover 30. The gas distribution plate 20 has a side end face facing the first fire cover 30 and a side end face facing away from the first fire cover 30. Taking the two end faces as the upper and lower end faces as an example, the first guide hole 24 connects the upper and lower end faces of the gas distribution plate 20, and the first fire cover 30 is covered on the top of the gas distribution plate 20. The first guide hole 24 forms an airflow channel that guides the airflow from the bottom of the gas distribution plate 20 to the first fire cover 30. The gas distribution plate 20 is in the shape of a disk, and the first guide holes 24 are arranged at intervals along the circumference of the gas distribution plate 20, so that the first guide holes 24 can be evenly spaced along the circumference of the gas distribution plate 20, so that the airflow transported to one side of the first fire cover 30 through the first guide holes 24 is in a uniform distribution state.

[0056] The first burner cap 30 is disposed on the gas distribution plate 20, and there is a gap between the surface of the first burner cap 30 facing the gas distribution plate 20 and the gas distribution plate 20, so that a plurality of the first gas chambers 313 are formed between the first burner cap 30 and the gas distribution plate 20. The plurality of the first gas chambers 313 form a plurality of gas mixing regions, and each of the first gas chambers 313 is connected to at least one of the first diversion holes 24, so that each of the first gas chambers 313 has at least one corresponding diversion channel, and each of the first gas chambers 313 can respectively have a corresponding air flow input end.

[0057] The gas distribution plate 20 can be used to divide the gas input into the burner, so that the gas can be dispersed and output from the plurality of the first diversion holes 24, thereby avoiding the problem of uneven air pressure at each part of the first burner cap 30 existing in the existing direct gas delivery to the first burner cap 30 part.

[0058] By making each of the first gas chambers 313 have at least one corresponding first diversion hole 24, when the air flow is delivered from the gas distribution plate 20 to the first gas chambers 313, the air flow is divided through each of the first diversion holes 24, so that the air flow can be dispersed and delivered into each of the first gas chambers 313. Since the air flow has been divided by the gas distribution plate 20 when entering each of the first gas chambers 313, sufficient gas can be input into each of the first gas chambers 313, and thus the air pressure in each of the first gas chambers 313 can be kept consistent. When the burner operates, the pressure of the mixed gas ejected from the first fire holes 311 corresponding to each of the first gas chambers 313 is also relatively more uniform, so that the flames generated at the first fire holes 311 corresponding to each of the first gas chambers 313 are relatively uniform, and the temperature distribution in the use state of the burner is also relatively more uniform, thereby avoiding the problem of deformation caused by uneven temperature at each position of the burner.

[0059] The first burner cap 30 is in a disc shape, and each of the first gas chambers 313 is evenly distributed along the circumferential direction of the first burner cap 30. Each of the first gas chambers 313 corresponds to a first diversion hole 24 respectively, so that the gas ejected from the first burner cap 30 burns to form a uniformly distributed flame outside the first burner cap 30. Since the first gas chambers 313 on the first burner cap 30 and the first diversion holes 24 on the gas distribution plate 20 are partitioned synchronously, when the air flow is dispersed and conveyed through the gas distribution plate 20 and then conveyed into each of the first gas chambers 313, the air pressures in each of the first gas chambers 313 are relatively consistent, so that the air pressure of the air flow ejected from the first burner cap 30 is kept consistent, thereby reducing the problem of uneven combustion flame temperature in different areas of the first burner cap 30 caused by different air pressures.

[0060] Since the gas conveyed into the burner is usually a mixed gas of fuel gas and air, the first gas chamber 313 can provide a mixing space for the fuel gas and air. When the air flow enters the space formed by each of the first gas chambers 313, the air flow can be fully mixed in the chamber. Due to the shunting of the air flow through the gas distribution plate 20 and the secondary mixing through the first gas chambers 313, the fuel gas and air in the air flow are mixed twice, and the uniformity of the air flow is better. When the air flow is output through each of the first fire holes 311, the fuel gas in the air flow can burn more fully, thereby helping to improve the combustion efficiency.

[0061] In an embodiment of the present invention, at the position of the first burner cap 30 corresponding to each of the first gas chambers 313, a first convex portion 314 is formed protruding away from the gas distribution plate 20, and the first fire hole 311 is arranged on the first convex portion 314. The first convex portion 314 forms an outward convex structure on the first burner cap 30, and a cavity is formed between the first convex portion 314 and the gas distribution plate 20, and the air flow enters the corresponding first gas chamber 313 from the first diversion hole 24.

[0062] On the side of the first burner cap 30 facing away from the gas distribution plate 20, a first diversion groove 312 is formed between adjacent first convex portions 314, which can be used to supplement secondary air into the first burner cap 30 to improve the combustion efficiency.

[0063] When forming the first gas chamber 313 with the first protrusion 314, the adjacent first gas chambers 313 can communicate with each other. Since the air flow has been split by the air distribution plate 20, after the air flow enters the corresponding first gas chamber 313 from the first diversion hole 24, when there is a pressure difference between the adjacent first gas chambers 313, the gas in the adjacent first gas chambers 313 can flow relatively, reducing the pressure difference in the adjacent first gas chambers 313, and further making the air pressure in the adjacent first gas chambers 313 consistent. When the burner operates, the pressure of the gas ejected from the first flame holes 311 corresponding to the adjacent first gas chambers 313 is consistent, thereby improving the combustion uniformity in different regions of the burner.

[0064] In another embodiment of the present invention, a partition is provided on the surface of the first burner cap 30 facing the air distribution plate 20. The adjacent partitions, the first burner cap 30, and the air distribution plate 20 enclose to form the first gas chamber 313, and the first gas chamber 313 is arranged in one-to-one correspondence with the first diversion hole 24. After the air flow is split by the air distribution plate 20, it enters the corresponding first gas chamber 313 along each first diversion hole 24.

[0065] In this embodiment, there may be a gap between the end of the partition close to the air distribution plate 20 and the air distribution plate 20, so that the adjacent first gas chambers 313 communicate with each other. When there is a pressure difference between the adjacent first gas chambers 313, the gas in the adjacent first gas chambers 313 can flow relatively, reducing the pressure difference in the adjacent first gas chambers 313, and further making the air pressure in the adjacent first gas chambers 313 consistent.

[0066] Please refer to Figure 7 、 Figure 8 and Figure 9 , in an embodiment of the present invention, an optional structure of the first burner cap 30 is disclosed. The first burner cap 30 includes: a first outer ring wall 32; and a first top wall 31. The first outer ring wall 32 is connected to the first top wall 31. The first flame holes 311 are provided on the first top wall 31. One end edge of the first outer ring wall 32 away from the first top wall 31 is provided with a first flanging 321, and the first flanging 321 is fixedly attached to the surface of the air distribution plate 20 facing away from the first top wall 31.

[0067] The first outer ring wall 32 is arranged in a ring shape at the outer peripheral part of the first top wall 31. One end of the first outer ring wall 32 away from the first top wall 31 is matched with the gas distribution plate 20, so that the first outer ring wall 32, the first top wall 31 and the gas distribution plate 20 form a cavity structure, and each of the first gas cavities 313 is formed by partitioning in the cavity.

[0068] One end edge of the first outer ring wall 32 away from the first top wall 31 bends towards the inside of the first outer ring wall 32 to form the first flanging 321. During installation, the first outer ring wall 32 is attached to the outer wall surface of the gas distribution plate 20, and one end of the first outer ring wall 32 away from the first top wall 31 is pressed into the inside of the first outer ring wall 32 until the first flanging 321 is attached to the surface of the gas distribution plate 20 on the side facing away from the first top wall 31.

[0069] When the first flanging 321 is attached to the surface of the gas distribution plate 20 on the side facing away from the first top wall 31, the first flanging 321 can be used to limit the first burner cap 30 from moving away from the gas distribution plate 20. A protruding support part can be arranged on the surface of the gas distribution plate 20 facing the first top wall 31. The support part can be in a ring structure, and one end of the support part away from the gas distribution plate 20 abuts against the surface of the first top wall 31 facing the gas distribution plate 20 to prevent the first burner cap 30 from moving towards the gas distribution plate 20.

[0070] When the burner is operating, due to the high temperature caused by combustion, the first burner cap 30 is prone to deformation, and the first burner cap 30 has a tendency to move away from the gas distribution plate 20. Under the action of the first flanging 321, the first burner cap 30 cannot move away from the gas distribution plate 20, so that the first burner cap 30 is kept in a preset position, thereby preventing the first burner cap 30 from being misaligned with the gas distribution plate 20.

[0071] Since the first flanging 321 can block the relative movement of the first burner cap 30, the first burner cap 30 can be kept in a preset state on the gas distribution plate 20, thereby avoiding the change in the local gas output due to the thermal deformation at the first flame holes 311 of the first burner cap 30, and further making the total gas output from the first flame holes 311 corresponding to the respective first gas cavities 313 of the first burner cap 30 keep in an equilibrium state.

[0072] Since the first flanging 321 is fixedly attached to the surface of the gas distribution plate 20 facing away from the first burner cap 30, the first flanging 321 can seal the side of the gas distribution plate 20 facing away from the first burner cap 30. When the burner is operating, the first burner cap 30 will expand and deform due to heat, and the first flanging 321 can seal the edge of the first burner cap 30, preventing a gap from forming between the first outer ring wall 32 and the gas distribution plate 20, and thus preventing leakage of fire at the connection between the first outer ring wall 32 and the gas distribution plate 20.

[0073] The first top wall 31 is disposed opposite to the gas distribution plate 20, and the first fire holes 311 are provided on the first top wall 31. When the gas flows from the first gas chamber 313 through the first fire holes 311 and jets out to the outside of the first burner cap 30, the gas will jet out in a direction away from the gas distribution plate 20. When there is local fire leakage between the first burner cap 30 and the gas distribution plate 20, it will cause changes in the gas pressure at different parts of the burner. The amount of gas jetted out from the first fire holes 311 will decrease, resulting in insufficient local pressure of the burner, and the temperature difference during combustion of the gas jetted out from different parts will further increase. In this embodiment, by blocking the first flanging 321 on the surface of the gas distribution plate 20 facing away from the first burner cap 30, the local pressure change caused by fire leakage can be reduced, the uniformity during the combustion of the burner can be further improved, the temperature difference between different parts of the first burner cap 30 can be reduced, thereby reducing the deformation of the first burner cap 30, and at the same time, the combustion efficiency of the gas can be improved.

[0074] When cleaning the burner, since the first outer ring wall 32 and the gas distribution plate 20 are connected to each other, the first burner cap 30 and the gas distribution plate 20 can be disassembled as a whole for cleaning. Since the first outer ring wall 32 can enclose the outer periphery of the gas distribution plate 20, when the burner is in use, the soup overflowing from the cookware is not easily introduced into the gap between the gas distribution plate 20 and the first burner cap 30, which can further facilitate the cleaning of the burner.

[0075] Please refer to Figure 4 、 Figure 5 and Figure 6, in an embodiment of the present invention, an optional structure of the gas distribution plate 20 is disclosed. The gas distribution plate 20 includes: a first mounting plate 21, which is arranged close to the first burner cap 30; a second mounting plate 22; and a plurality of support seats 23, which are connected between the first mounting plate 21 and the second mounting plate 22. The support seats 23 are hollow inside, and through holes communicating with the corresponding support seats 23 are provided on the first mounting plate 21 and the second mounting plate 22 to form the first flow guiding holes 24; the first flanging 321 is fixedly attached to the surface of the first mounting plate 21 facing away from the first burner cap 30.

[0076] The support seats 23 are arranged in one-to-one correspondence with the first flow guiding holes 24, so that air flow enters the support seats 23 through the through holes on the second mounting plate 22, and enters the corresponding first gas cavity 313 through the through holes on the support seats 23 and the first mounting plate 21. The first flanging 321 can be fixedly attached to the surface of the first mounting plate 21 facing the second burner cap 50 in the vicinity.

[0077] By adopting the design method of the first mounting plate 21 and the second mounting plate 22, the first mounting plate 21 can be arranged close to the first burner cap 30. When the first outer ring wall 32 cooperates with the first mounting plate 21, the axial length of the first outer ring wall 32 can be relatively reduced, and thus the volume of the first burner cap 30 can be reduced.

[0078] The second burner cap 50 can be used to adapt to other functional components of the burner, such as the burner head 10, etc. The support seats 23 are used to support between the first mounting plate 21 and the second mounting plate 22, and can be used to form the first flow guiding holes 24.

[0079] The first mounting plate 21 and the second mounting plate 22 can be in a disc-shaped structure or an annular structure, and can be configured according to the design of the burner head 10 of the burner.

[0080] Since there are a plurality of the first flow guiding holes 24, and the first flow guiding holes 24 are in one-to-one correspondence with the support seats 23, secondary air inlets 27 can be formed between adjacent support seats 23 for supplementing secondary air into the first burner cap 30, and thus the combustion efficiency of the burner can be improved.

[0081] Optionally, in this embodiment, a central hole 25 is provided in the first mounting disc 21; the first burner cap 30 further includes an inner ring wall 33, the first outer ring wall 32 is disposed outside the inner ring wall 33, one end of the inner ring wall 33 is connected to the first top wall 31, the other end of the inner ring wall 33 extends into the central hole 25, a second flanging 331 is provided at the end of the inner ring wall 33 away from the first top wall 31, and the second flanging 331 is fixedly attached to the surface of the first mounting disc 21 on the side facing away from the first top wall 31.

[0082] The first mounting disc 21 is integrally circular. The first outer ring wall 32 and the inner ring wall 33 are both disposed on the same side of the first top wall 31. The first outer ring wall 32, the first top wall 31, the first mounting disc 21, and the inner ring wall 33 form a cavity, and a plurality of the first gas chambers 313 are partitioned in the cavity.

[0083] The second flanging 331 is formed by bending the edge of the end of the inner ring wall 33 away from the first top wall 31 towards the outer ring wall. The second flanging 331 is fixedly attached to the surface of the first mounting disc 21 on the side facing the second mounting disc 22.

[0084] The second flanging 331 can limit the deformation of the first burner cap 30 from the inside of the first mounting disc 21, preventing the first burner cap 30 from deforming. At the same time, the second flanging 331 can prevent the problem of fire leakage between the first mounting disc 21 and the inner ring wall 33.

[0085] By making the first flanging 321 and the second flanging 331 fixedly attached to the surface of the first mounting disc 21 on the side facing away from the first burner cap 30, rapid positioning of the first burner cap 30 can be achieved. Since the first burner cap 30 is connected to the first mounting disc 21 through both the first flanging 321 and the second flanging 331 at the same time, the first burner cap 30 can be maintained in a preset position, preventing the first burner cap 30 from shifting. The first diversion hole 24 can also maintain a good corresponding state with the corresponding first gas chamber 313, which further helps to keep the gas input of the first gas chamber 313 in a preset state.

[0086] Further optionally, the inner ring wall 33, the first outer ring wall 32, and the first top wall 31 are integrally provided. The inner ring wall 33, the first outer ring wall 32, and the first top wall 31 can be integrally formed by stamping, or other integral processing methods can also be used.

[0087] Please refer to Figures 10 to 13, in an embodiment of the present invention, a plurality of second diversion holes 26 are provided on the second mounting plate 22; a second burner cap 50 is covered on the second mounting plate 22, and a plurality of second gas chambers 512 are formed by enclosing the second burner cap 50 and the second mounting plate 22. A plurality of second flame holes 511 are provided on the second burner cap 50 at positions corresponding to the respective second gas chambers 512, and the plurality of second flame holes 511 communicate with the second gas chambers 512 at corresponding positions; at least one second diversion hole 26 corresponds to the position of each second gas chamber 512 and they are interconnected.

[0088] The second burner cap 50 is located inside the central hole 25. The burner, from outside to inside, is successively the first outer ring wall 32, the inner ring wall 33, and the second burner cap 50. The second burner cap 50 forms an inner ring burner cap inside the first burner cap 30. The second burner cap 50 and the surface of the second mounting plate 22 facing the second burner cap 50 form the second gas chamber 512.

[0089] The plurality of second diversion holes 26 are used to introduce gas into the corresponding plurality of second gas chambers 512. By providing the second gas chamber 512, after the gas enters the second gas chamber 512, there is space for sufficient mixing, which can help improve the gas combustion efficiency. Since the second diversion holes 26 are provided on the gas distribution plate 20 and the second burner cap 50 is installed on the gas distribution plate 20, when the gas distribution plate 20 is installed on components such as the burner head 10, the positions of the first burner cap 30 and the second burner cap 50 are also relatively determined, facilitating the installation of the first burner cap 30 and the second burner cap 50.

[0090] Please refer to Figure 14 , the burner further includes a burner head 10. The burner head 10 is provided with a first gas passage 11 and a second gas passage 12. The first gas passage 11 is used to convey gas to the first gas chamber 313 through the first diversion hole 24, and the second gas passage 12 is used to convey gas to the second gas chamber 512 through the second diversion hole 26. A first intake pipeline 111 communicating with the first gas chamber 313 and a second intake pipeline 121 communicating with the second gas chamber 512 are provided outside the burner head 10.

[0091] By forming a plurality of the second gas cavities 512 between the second burner cap 50 and the second mounting plate 22, when the air flow enters the second gas cavities 512 through a plurality of the second diversion holes 26, the air flow has been diverted through the second diversion holes 26, enabling the air flow to enter the second gas cavities 512 evenly and dispersedly. Furthermore, the air pressure in each of the second gas cavities 512 can be kept consistent, reducing the problem of uneven heating caused by other unevenness. By improving the combustion uniformity of the gas output from the second gas cavities 512, the second burner cap 50 can be heated evenly, preventing the second burner cap 50 from being deformed due to uneven heating.

[0092] Optionally, in this embodiment, the distance between the second flame holes 511 and the second mounting plate 22 is less than the distance between the first flame holes and the second mounting plate 22. Taking the state in Figure 3 as an example, the height of the plane where the flame holes on the second burner cap 50 are located is lower than the height of the flame holes on the first burner cap 30. When the mixed gas burns, since the temperature of the outer flame is the highest, when the gas in the second burner cap 50 is ejected and burned, the outer flame height of the flame at the central part of the burner is relatively low, and a high-temperature area can be formed in the middle of the burner, enabling the high-temperature area of the flame generated by the second burner cap 50 to act on the bottom of the cookware, thereby improving the utilization efficiency of heat.

[0093] Since the parts of the first burner cap 30 corresponding to each of the first gas cavities 313 are divided into a plurality of combustion areas, secondary air can be supplemented between adjacent combustion areas. When the height of the second burner cap 50 is relatively low, the secondary air supplemented by the first burner cap 30 can directly act on the combustion areas on the second burner cap 50, making the combustion of the gas more sufficient, and thus helping to improve the gas combustion efficiency at the second burner cap 50.

[0094] In an embodiment of the present invention, an optional way to form the second gas cavities 512 is disclosed. At the positions on the second burner cap 50 corresponding to each of the second gas cavities 512, second convex portions 513 protrude away from the second mounting plate 22, and the second flame holes 511 are provided on the second convex portions 513. By adopting the second convex portions 513, a groove structure can be formed between the combustion areas corresponding to adjacent second gas cavities 512, and this groove can serve as a second diversion groove 53 for supplementing secondary air to the middle of the second burner cap 50.

[0095] For rapid ignition, in this embodiment, a flame transfer hole 55 is provided on the side wall of the second gas cavity 521 close to the second diversion groove 53 for achieving rapid ignition at the second burner cap 50 during ignition.

[0096] By protruding the second burner cap 50 away from the second mounting plate, the volume of the second gas chamber 512 is increased. When the gas flow enters the second gas chamber 512 from the second diversion hole 26, there is space for mixing, so that the gas and air can be fully mixed, which helps to improve the combustion efficiency of the gas.

[0097] Alternatively, a partition can be provided on the surface of the second burner cap 50 facing the second mounting plate to divide and form a plurality of the second gas chambers 512. The adjacent second gas chambers 512 can communicate with each other to balance the air pressure in the adjacent second gas chambers 512.

[0098] In an embodiment of the present invention, a burner cap seat 40 is provided on the second mounting disc 22, and a step surface facing the second mounting disc 22 is formed on the outer periphery of the burner cap seat 40; the second burner cap 50 includes a second top wall 51 and a second outer ring wall 52, the second top wall 51 is provided on the side of the burner cap seat 40 away from the second mounting disc 22, and the second burner holes 511 are provided on the second top wall 51; the second outer ring wall 52 is disposed around the outside of the burner cap seat 40, one end of the second outer ring wall 52 is connected to the second top wall 51, and the other end of the second outer ring wall 52 is provided with a third flanging 521, and the third flanging 521 is fixedly attached to the step surface.

[0099] The second outer ring wall 52 can be integrally provided with the second top wall 51. The second outer ring wall 52, the top wall and the second mounting plate enclose a cavity, and a plurality of the second gas chambers 512 are divided and formed in the cavity. A middle ring burner hole 54 can be provided on the second outer ring wall 52 to jet combustion into the gap between the second outer ring wall 52 and the inner ring wall 33.

[0100] The second top wall 51 is disposed opposite to the second mounting disc 22, and one end of the second outer ring wall 52 away from the second top wall 51 is bent inward to form the third flanging 521.

[0101] The burner cap seat 40 and the second mounting disc 22 are fixedly connected to each other, and the third flanging 521 is attached to the step surface of the burner cap seat 40 facing away from the second top wall 51, so that the second outer ring wall 52 is fixedly connected to the burner cap seat 40 through the third flanging 521, and the second burner cap 50 cannot move away from the second mounting disc 22.

[0102] By setting the third flanging 521, the second burner cap 50 can be fixed on the second mounting plate 22. At this time, the second burner cap 50, the gas distribution plate 20 and the first burner cap 30 can form an integral structure. When the burner needs to be cleaned, the gas distribution plate 20 can be directly detached from the burner head 10 for overall cleaning.

[0103] When the burner is operating, the second burner cap 50 expands due to heat and tends to move away from the second mounting plate 22. The second flanging 331 can prevent the second burner cap 50 from displacing, thereby avoiding flame leakage between the second burner cap 50 and the burner cap seat 40. During the operation of the burner, when the soup overflowing from the cookware flows along the second burner cap 50, the second flanging 331 can completely block the gap between the second burner cap 50 and the burner cap seat 40, thereby preventing foreign matters from accumulating at the connection between the second burner cap 50 and the burner cap seat 40.

[0104] Both the first burner cap 30 and the second burner cap 50 are arranged on the same side of the second mounting plate 22. When the gas distribution plate 20 is installed on the burner, the soup overflowing from the cookware can flow outward along the second mounting plate 22 and flow out through the secondary air inlet 27 between the adjacent support seats 23, thereby facilitating the cleaning of the burner and reducing blockage.

[0105] Based on the above burner, the present invention proposes an embodiment of a gas stove.

[0106] The gas stove includes the burner as described in any of the above embodiments.
