Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0035] In related technologies, poor cooking results can occur when a burner heats a pot. The inventors discovered that this problem arises because the multiple outer ring flame holes on the hexagonal outer burner cap are arranged circumferentially, and at least two of these holes emit flames of inconsistent lengths. This results in uneven temperature distribution at the bottom of the pot, causing some areas of food to burn or stick while others remain uncooked, leading to poor cooking results.

[0036] To address the aforementioned issues, the burner, stove, and integrated stove provided in this application embodiment feature multiple outer ring flame holes on each side of the outer burner cap, spaced sequentially along the edge of the outer burner cap body. The parallel arrangement of these outer ring flame holes on each side ensures that the dimensions of the outer ring flame holes on the outer periphery of the outer burner cap are identical in their extending direction. This results in consistent flame lengths from each outer ring flame hole when the burner heats the bottom of the pot, leading to uniform temperature distribution at the bottom of the pot and improved cooking performance. Furthermore, the parallel arrangement of the outer ring flame holes on each side avoids flame cross-interference and turbulence, preventing obstruction of secondary air supply.

[0037] The burner, stove and integrated stove provided in this application will be described in detail below with reference to specific embodiments.

[0038] In a first aspect, embodiments of this application provide a burner applied to the cooktop of an integrated stove. The integrated stove includes a lower-level unit, a cooktop, and a burner assembly. The lower-level unit mainly provides storage cabinet space and space for installing an oil fume treatment device. The cooktop mainly achieves cooking through the burner, and the burner assembly is mainly used in conjunction with the oil fume treatment device to generate negative pressure to absorb the oil fumes generated during cooking.

[0039] The height direction of the burner is the Z-direction (see...) Figure 6 (As shown). The +Z side of the burner is the top of the burner, i.e., the upper part of the burner. The -Z side of the burner is the bottom of the burner, i.e., the lower part of the burner.

[0040] See Figure 1 and Figure 2 As shown, the burner includes an outer burner cap 10 and an inner burner cap 20, with the inner burner cap 20 located inside the outer burner cap 10.

[0041] See in some examples Figures 2 to 4 As shown, the outer flame cap 10 has a circular through hole 101, and the inner flame cap 20 is located in the through hole 101. The outer flame cap 10 is provided with an outer ring flame hole 112 and a middle ring flame hole 115, and the inner flame cap 20 is provided with an inner ring flame hole 201. The middle ring flame hole 115 is located between the outer ring flame hole 112 and the inner ring flame hole 201.

[0042] The outer flame cover 10 is polygonal in shape. The outer flame cover 10 includes an outer flame cover body 11, and a plurality of first side surfaces 111 are provided on the outer periphery of the outer flame cover body 11. The plurality of first side surfaces 111 intersect sequentially along the edge of the outer flame cover body 11. Adjacent first side surfaces 111 are connected.

[0043] Figure 4 The diagram shows the center lines of the outer ring flash holes 112 on each first side 111. The center lines of the outer ring flash holes 112 on each first side 111 are parallel, that is, the outer ring flash holes 112 on each first side 111 are parallel. The outer ring flash holes 112 extend along their center lines.

[0044] See Figure 3 and Figure 4 As shown, each first side 111 is provided with multiple outer ring flame holes 112, which are arranged sequentially and at intervals along the edge of the outer burner cap body 11. The outer ring flame holes 112 on each first side 111 are arranged in parallel. This arrangement ensures that the outer ring flame holes 112 on each first side 111 have the same size in their extending direction. Therefore, when the burner heats the bottom of the pot, the flame lengths ejected from the outer ring flame holes 112 on the outer burner cap 10 are consistent, resulting in a uniform temperature distribution at the bottom of the pot and improving cooking performance. Furthermore, the parallel arrangement of the outer ring flame holes on each first side 111 avoids flame cross-interference and turbulence caused by the flames of the outer ring flame holes 112 on each first side 111, and does not obstruct secondary air supply.

[0045] In some examples, the outer flame cap 10 is a hexagonal flame cap. The outer periphery of the outer flame cap body 11 is provided with six first side surfaces 111. The first side surfaces 111 are planar, and the extension direction of the outer ring flame holes 112 intersects with the first side surfaces 111. It can be understood that the extension direction of the outer ring flame holes 112 is not parallel to the first side surfaces 111.

[0046] In some examples, multiple outer ring flame holes 112 are arranged at equal intervals along the edge of the outer flame cap body 11. This arrangement ensures that the flames of each outer ring flame hole 112 on each first side 111 do not interfere with each other, guaranteeing sufficient secondary air supply during combustion of the outer ring flame holes 112. This avoids incomplete combustion and prevents flame drift or detachment under high load conditions, which helps reduce smoke and improve energy efficiency.

[0047] In one possible implementation, the outer flame cap 10 also includes a plurality of protrusions 12 (see...). Figure 3 As shown), multiple protrusions 12 are provided on the top of the outer flame cover body 11, and the multiple protrusions 12 are arranged sequentially at intervals along the edge of the outer flame cover body 11.

[0048] In some examples, see Figure 4As shown, the outer flame cover 10 includes six protrusions 12. The protrusions 12 include a first inclined surface 121, a second inclined surface 122, a third inclined surface 123, a first arc surface 124, and a second arc surface 125.

[0049] The first inclined plane 121, the second inclined plane 122, and the third inclined plane 123 are all planes.

[0050] The first inclined surface 121 is connected to the first side surface 111. The top of the first inclined surface 121 is inclined towards the inside of the outer flame cap 10 relative to the bottom of the first inclined surface 121. The outer ring flame hole 112 is located below the extending direction of the first inclined surface 121.

[0051] The first arc surface 124 is connected between the first inclined surface 121 and the second inclined surface 122, and both the first inclined surface 121 and the second inclined surface 122 are tangent to the first arc surface 124.

[0052] The second arc surface 125 connects the second inclined surface 122 and the third inclined surface 123, and both the second inclined surface 122 and the third inclined surface 123 are tangent to the second arc surface 125.

[0053] The outer flame cover body 11 has a channel 113 between two adjacent protrusions 12 (see Figure 3 As shown, a second side surface 114 is provided between the top of the protrusion 12 and the bottom of the channel 113, and multiple central ring flame holes 115 are provided on the second side surface 114. This arrangement allows the burner to form a three-ring flame, which is beneficial for uniform temperature at the bottom of the pot.

[0054] Channel 113 penetrates the outer periphery of outer fire cover 10 and through hole 101.

[0055] The second side 114 is connected to the first side 111 and the second inclined surface 122. The top of the second inclined surface 122 is inclined away from the channel 113 relative to the bottom of the second inclined surface 122, and the central ring fire hole 115 is located below the extending direction of the second inclined surface 122.

[0056] The second side 114 is part of the channel 113. In addition to the second side 114, the channel 113 also includes a third side 117, which connects to the first side 111, the second side 114, and the third inclined surface 123. The top of the third inclined surface 123 slopes away from the channel 113 relative to its bottom. The tops of the first inclined surface 121, the second inclined surface 122, and the third inclined surface 123 intersect at the apex of the protrusion 12.

[0057] Figure 4The diagram shows the center lines of the various central ring flash holes 115 on each second side 114. The center lines of the various central ring flash holes 115 on each second side 114 are parallel, that is, the various central ring flash holes 115 on each second side 114 are parallel. The central ring flash holes 115 extend along their center lines.

[0058] In one possible implementation, see Figure 4 As shown, multiple central ring flame holes 115 are arranged at intervals along the extension direction of the channel 113, and the central ring flame holes 115 on the second side 114 are arranged in parallel. This arrangement ensures that the central ring flame holes 115 on each of the second side 114 have the same size in their extension direction. Therefore, when the burner heats the bottom of the pot, the flame lengths ejected by the central ring flame holes 115 on the outer burner cover 10 are consistent, resulting in a uniform temperature distribution at the bottom of the pot and thus improving the cooking effect.

[0059] The second side 114 is a plane, and the extension direction of the middle ring fire hole 115 intersects with the second side 114. It can be understood that the extension direction of the middle ring fire hole 115 is not parallel to the second side 114.

[0060] In some examples, multiple central ring flame holes 115 on each second side 114 are arranged at equal intervals along the extension direction of the channel 113. This arrangement ensures that the central ring flame holes 115 have sufficient secondary air supply during combustion, avoiding incomplete combustion and preventing flame drift or detachment under high load conditions, which helps reduce flue gas and improve energy efficiency.

[0061] In one possible implementation, see Figure 2 , Figure 6 and Figure 7 As shown, the burner also includes a burner head 30, a gas distribution seat 40, and a partition plate 50. The burner head 30 is connected to the gas distribution seat 40, the gas distribution seat 40 is connected to the outer flame cover 10, and the partition plate 50 is connected between the gas distribution seat 40 and the outer flame cover 10.

[0062] The gas distribution seat 40 is connected to the outer flame cover 10 by screws. The partition plate 50 is also connected to the outer flame cover 10 by screws. The assembled assembly of the gas distribution seat 40, partition plate 50, and outer flame cover 10 is placed above the burner head 30.

[0063] The burner head 30 includes an outer ring ejector tube 31, a middle ring ejector tube 32 and an inner ring ejector tube 33. The outer ring ejector tube 31 is connected to the outer ring nozzle 34, the middle ring ejector tube 32 is connected to the middle ring nozzle 35, and the inner ring ejector tube 33 is connected to the inner ring nozzle 36.

[0064] The burner head 30 includes an outer ring premixing chamber connected to the outer ring ejector tube 31, a middle ring premixing chamber connected to the middle ring ejector tube 32, and an inner ring premixing chamber connected to the inner ring ejector tube 33.

[0065] The burner also includes a thermocouple 60 and an electrode needle 70, which are mounted on the burner head 30. The electrode needle 70 is used to ignite the gas, forming a cooking flame. The thermocouple 60 is used to monitor the flame temperature in real time during burner operation to maintain the flame.

[0066] The gas distributor 40 is provided with an outer cavity 401 and an inner cavity 402. The outer ring premixing cavity is connected to the outer cavity 401, and the middle ring premixing cavity is connected to the inner cavity 402.

[0067] The partition plate 50 is provided with a partition air passage 501, which is connected to the inner cavity 402.

[0068] The outer cavity 401 is connected to the outer ring flame port 112. The dividing air passage 501 is connected to the middle ring flame port 115. The inner ring premixing cavity is connected to the inner ring flame port 201.

[0069] When the stove is working, gas is injected into the inner ring nozzle 36, middle ring nozzle 35, and outer ring nozzle 34 into the inner ejector tube 33, middle ejector tube 32, and outer ejector tube 31, respectively. Gas and air in the inner ejector tube 33 mix in the inner ring premixing chamber; gas and air in the middle ejector tube 32 mix in the middle ring premixing chamber; and gas and air in the outer ejector tube 31 mix in the outer ring premixing chamber. Gas in the inner ring premixing chamber is then ejected from the inner ring burner hole 201 for combustion. Gas in the middle ring premixing chamber enters the inner cavity 402 of the gas distributor 40 and is ejected from the middle ring burner hole 115 through the dividing gas passage 501 for combustion. Gas in the outer ring premixing chamber enters the outer cavity 401 of the gas distributor 40 and is directly ejected from the outer ring burner hole 112 for combustion.

[0070] The burner can be transformed into three flame shapes to suit the user's cooking needs.

[0071] The first type of flame configuration includes an inner ring flame, a middle ring flame, and an outer ring flame; that is, flames are emitted from the inner ring flame hole 201, the middle ring flame hole 115, and the outer ring flame hole 112. The power range corresponding to the first type of flame configuration is 3kW to 5.2kW. The first type of flame configuration is suitable for stir-frying or steaming.

[0072] The second type of flame configuration includes an inner ring flame and a middle ring flame; that is, both the inner ring flame hole 201 and the middle ring flame hole 115 emit flame, while the outer ring flame hole 112 does not emit flame. The power range corresponding to this second type of flame configuration is 1.5kW to 2.5kW. This second type of flame configuration is suitable for frying, stewing, and other similar activities.

[0073] The third type of flame configuration includes an inner ring flame, meaning that the inner ring flame hole 201 emits flame, while the middle ring flame hole 115 and the outer ring flame hole 112 do not emit flame. The power range corresponding to this third type of flame configuration is 0.45kW to 0.8kW. This third type of flame configuration is suitable for simmering soup or keeping food warm.

[0074] See in some examples Figure 6 and Figure 7 As shown, the gas distribution seat 40 is disposed at the bottom of the outer flame cap body 11. The gas distribution seat 40 has an outer cavity 401 communicating with the outer ring flame hole 112. A flame stabilizing groove 801 communicating with the outer cavity 401 is disposed between the gas distribution seat 40 and the outer flame cap body 11. The flame stabilizing groove 801 is used to transfer flame to the outer ring flame hole 112. With this configuration, the flame stabilizing groove 801 can provide a continuous flame source to the outer ring flame hole 112, improving the stability of the flame combustion in the outer ring flame hole 112.

[0075] The gas distribution seat 40 has a top surface 403, and the outer flame cap body 11 has a mating bottom surface 102 that is opposite to the top surface 403. A flame stabilizing groove 801 is formed between the top surface 403 and the mating bottom surface 102. The flame stabilizing groove 801 is arranged around the edge of the outer flame cap body 11.

[0076] The outer flame cap body 11 has a first inner wall 118 parallel to the inner wall of the outer cavity 401. The first inner wall 118 and the inner wall of the outer cavity 401 form an outlet groove 802 that communicates with the flame stabilizing groove 801. With this configuration, the gas in the outer cavity 401 can be supplied to the flame stabilizing groove 801 through the outlet groove 802.

[0077] In some examples, the outer flame cap body 11 has a second inner wall 119 that intersects with the first inner wall 118. The second inner wall 119 and the inner wall of the outer cavity 401 form a flared opening 803 that communicates with the gas outlet groove 802. With this configuration, the flared opening 803 helps to concentrate the gas, and the gas flow rate is reduced through the gas outlet groove 802, thereby achieving flame stabilization through the flame stabilization groove 801.

[0078] Among them, the cross-sectional area of ​​the flared mouth 803 gradually decreases from the end away from the air outlet 802 toward the end closer to the air outlet 802.

[0079] The angle α between the second inner wall 119 and the inner wall of the outer cavity 401 is greater than 0° and less than 90°.

[0080] In one possible implementation, a flame transfer section 116 is provided at the bottom of the channel 113. The flame transfer section 116 is used to transfer flame between the middle ring flame hole 115 and the outer ring flame hole 112. Specifically, the flame transfer section 116 can transfer the flame from the middle ring flame hole 115 to the flame stabilizing groove 801, and the flame stabilizing groove 801 then transfers the flame to the outer ring flame hole 112.

[0081] Among them, see Figure 5 As shown, the flame transfer section 116 can be a flame transfer groove, which penetrates the outer periphery of the outer flame cover 10.

[0082] In other embodiments, see Figure 8As shown, the flame transfer section 116 can also be a flame transfer hole. Multiple flame transfer holes are provided at the bottom of the channel 113.
