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.

[0028] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

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.

[0032] In related technologies, the heat needs to be repeatedly adjusted during stewing, making the operation cumbersome. The inventors discovered that this problem arises because the burner only has inner and outer ring flames; the lack of a central ring flame necessitates repeated adjustments to the appropriate heat level during stewing, leading to cumbersome operation.

[0033] To address the aforementioned issues, embodiments of this application provide a burner, stove, and integrated stove that incorporates a central ring flame, with independent control of the outer, central, and inner ring flames. This allows the burner to provide both the inner and central ring flames during stewing, eliminating the need for repeated flame adjustments and simplifying operation.

[0034] The burner, stove and integrated stove provided in this application will be described in detail below with reference to specific embodiments.

[0035] 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.

[0036] The burner includes the burner body and the flame cap structure.

[0037] See Figure 1 and Figure 2 As shown, the burner body is provided with an outer ring ejector tube 11, a middle ring ejector tube 12 and an inner ring ejector tube 13.

[0038] The burner body has a first channel, a second channel and a third channel inside. The outer ring ejector tube 11 is connected to the first channel, the middle ring ejector tube 12 is connected to the second channel and the inner ring ejector tube 13 is connected to the third channel.

[0039] The flame cap structure is provided with an outer ring flame hole 711, a middle ring flame hole 712 and an inner ring flame hole 721. The middle ring flame hole 712 is located between the outer ring flame hole 711 and the inner ring flame hole 721. The outer ring flame hole 711 is connected to the first channel, the middle ring flame hole 712 is connected to the second channel, and the inner ring flame hole 721 is connected to the third channel.

[0040] The burner body includes an outer ring nozzle 61, a middle ring nozzle 62, and an inner ring nozzle 63. The outer ring nozzle 61 is connected to the outer ring ejector tube 11, the middle ring nozzle 62 is connected to the middle ring ejector tube 12, and the inner ring nozzle 63 is connected to the inner ring ejector tube 13. This arrangement allows the burner to have three independent ejector tubes, which is beneficial for precise temperature control and improves cooking results.

[0041] See in some examples Figure 3 As shown, the burner cap structure includes an outer burner cap 71 and an inner burner cap 72. The outer burner cap 71 covers the inner burner cap 72. An outer ring burner hole 711 and a middle ring burner hole 712 are provided on the outer burner cap 71, and an inner ring burner hole 721 is provided on the inner burner cap 72. The outer burner cap 71 is provided with a middle ring air passage 713 communicating with the middle ring burner hole 712, and the inner burner cap 72 is provided with an inner ring air passage 722 communicating with the inner ring burner hole 721.

[0042] Both the outer flame cap 71 and the inner flame cap 72 are made of copper.

[0043] The gas ejected from the outer ring nozzle 61 carries the surrounding air into the outer ring ejector tube 11, then into the first channel, and then burns from the outer ring flame hole 711.

[0044] The gas ejected from the central ring nozzle 62 draws the surrounding air into the central ring ejector tube 12, then into the second channel, and finally burns through the central ring burner hole 712.

[0045] The gas ejected from the inner ring nozzle 63 carries the surrounding air into the inner ring ejector tube 13, then into the third channel, and then burns from the inner ring flame hole 721.

[0046] The burner provided in this application embodiment is connected to the first channel via the outer ring ejector tube 11 of the burner body, the second channel via the middle ring ejector tube 12, and the third channel via the inner ring ejector tube 13. The first channel is connected to the outer ring flame hole 711, the second channel is connected to the middle ring flame hole 712, and the third channel is connected to the inner ring flame hole 721. The middle ring flame hole 712 is located between the outer ring flame hole 711 and the inner ring flame hole 721, which allows the outer ring flame, middle ring flame, and inner ring flame to be controlled independently. Thus, when stewing, the burner can provide inner ring flame and middle ring flame without repeated flame adjustment, making operation simple.

[0047] In one possible implementation, see Figures 1 to 3 As shown, the burner body includes a burner head 10, a gas distribution seat 20, and a partition plate 30. The burner head 10 is connected to the gas distribution seat 20, the gas distribution seat 20 is connected to the flame cap structure, and the partition plate 30 is connected between the gas distribution seat 20 and the flame cap structure.

[0048] The first channel passes through the burner head 10 and the gas distributor 20; the second channel passes through the burner head 10, the gas distributor 20, and the partition plate 30; and the third channel passes through the burner head 10. With this arrangement, the gas ejected from the outer ring nozzle 61 carries the surrounding air into the burner head 10 and the gas distributor 20, and then burns through the outer ring flame hole 711. The gas ejected from the middle ring nozzle 62 carries the surrounding air into the burner head 10, the gas distributor 20, and the partition plate 30, and then enters the middle ring gas passage 713, where it burns through the middle ring flame hole 712. The gas ejected from the inner ring nozzle 63 carries the surrounding air into the burner head 10, and then enters the inner ring gas passage 722, where it burns through the inner ring flame hole 721.

[0049] The height of the burner is in the Z-direction. The area below the burner is in the -Z-direction. The area above the burner is in the +Z-direction.

[0050] The burner head 10 includes an outer ring ejector tube 11, a middle ring ejector tube 12 and an inner ring ejector tube 13. It can be understood that the outer ring nozzle 61, the middle ring nozzle 62 and the inner ring nozzle 63 are assembled on the burner head 10.

[0051] See Figure 3As shown, the burner head 10 includes an outer ring premixing chamber 101 connected to the outer ring ejector tube 11, a middle ring premixing chamber 102 connected to the middle ring ejector tube 12, and an inner ring premixing chamber 103 connected to the inner ring ejector tube 13. The gas ejected from the outer ring nozzle 61 draws surrounding air into the outer ring ejector tube 11, and then into the outer ring premixing chamber 101 for mixing. The gas ejected from the middle ring nozzle 62 draws surrounding air into the middle ring ejector tube 12, and then into the middle ring premixing chamber 102 for mixing. The gas ejected from the inner ring nozzle 63 draws surrounding air into the inner ring ejector tube 13, and then into the inner ring premixing chamber 103 for mixing.

[0052] See Figure 2 As shown, the burner head 10 is provided with an outer ring gas outlet 104 that communicates with the outer ring premixing chamber 101, a middle ring gas outlet 105 that communicates with the middle ring premixing chamber 102, and an inner ring gas outlet 106 that communicates with the inner ring premixing chamber 103.

[0053] In some examples, the burner head 10 has a first protrusion 14 and three second protrusions 15 above it, with the three second protrusions 15 evenly spaced around the first protrusion 14. Each second protrusion 15 has an outer ring air outlet 104 and a middle ring air outlet 105, and the first protrusion 14 has an inner ring air outlet 106. The middle ring air outlet 105 is located between the outer ring air outlet 104 and the inner ring air outlet 106.

[0054] See Figure 2 As shown, the burner body also includes a thermocouple 40 and an electrode needle 50, which are mounted on the burner head 10 and located between the inner ring gas outlet 106 and the middle ring gas outlet 105. The electrode needle 50 is used to ignite the combustion gas to form a cooking flame. The thermocouple 40 is used to monitor the flame temperature in real time during the burner's operation to maintain the flame.

[0055] The inner flame cap 72 of the flame cap structure is installed above the inner ring outlet 106.

[0056] See Figure 4 and Figure 5 As shown, the outer flame cover 71 has an outer flame cover bottom surface 714, a gas distribution seat fixing hole 715, and a partition plate fixing hole 716.

[0057] The partition plate 30 has a top surface 302, a limiting hole 303, and a mounting hole 304 (see [reference]). Figure 2(As shown). The partition plate 30 is nested inside the outer flame cap 71. The top surface 302 of the partition plate 30 and the bottom surface 714 of the outer flame cap 71 are sealed together by a plane. The partition plate limiting hole 303 of the partition plate 30 is nested outside the gas distribution seat fixing hole 715 of the outer flame cap 71. The partition plate mounting hole 304 of the partition plate 30 is nested outside the partition plate fixing hole 716 of the outer flame cap 71. Then, the partition plate 30 and the outer flame cap 71 are fixedly locked by screws passing through the partition plate mounting hole 304 and the partition plate fixing hole 716.

[0058] The gas distributor seat 20 is located below the outer flame cap 71. The gas distributor seat 20 has a gas distributor seat mounting hole 203 and a gas distributor seat limiting protrusion 204 (see...). Figure 2 (As shown). By passing screws through the gas distributor mounting hole 203 and the gas distributor fixing hole 715, the gas distributor 20 is fixedly locked to the outer flame cover 71.

[0059] The assembled components of the gas distribution seat 20, the partition plate 30, and the outer flame cover 71 are installed above the burner head 10. The gas distribution seat 20 is located between two second protrusions 15 by two gas distribution seat limiting protrusions 204, and the two gas distribution seat limiting protrusions 204 abut against the two second protrusions 15 respectively, in order to prevent the gas distribution seat 20 from rotating relative to the burner head 10, thereby ensuring that the outer ring premixing chamber 101 is connected to the first gas passage 201 and the middle ring premixing chamber 102 is connected to the second gas passage 202.

[0060] In one possible implementation, the air distribution seat 20 is provided with a first air passage 201 and a second air passage 202, which are separated by a partition plate 30 (see [link]). Figure 3 (As shown). This configuration ensures that the gas in the first gas duct 201 and the second gas duct 202 do not interfere with each other.

[0061] The gas distribution seat 20 and the burner head 10 are fitted together by a planar seal. The outer ring premixing chamber 101 is connected to the first gas passage 201, and the middle ring premixing chamber 102 is connected to the second gas passage 202.

[0062] The gas distributor 20 and the outer flame cap 71 are fitted together by a planar seal to enable the first gas passage 201 to communicate with the outer ring flame hole 711.

[0063] The partition plate 30 is provided with a partition airway 301, which is connected to the second airway 202. This configuration can separate the first airway 201 and the second airway 202.

[0064] The partition plate 30 and the outer flame cap 71 are fitted together by a planar seal to separate the air passage 301 from the middle ring air passage 713 (see...). Figure 4 (As shown) connected.

[0065] The outer ring premixing chamber 101 and the first air passage 201 form the first channel, the middle ring premixing chamber 102, the second air passage 202 and the separating air passage 301 form the second channel, and the inner ring premixing chamber 103 forms the third channel. This arrangement allows the burner to form three independent channels.

[0066] When the stove is working, gas is injected into the inner ring nozzle 63, middle ring nozzle 62, and outer ring nozzle 61, respectively, into the inner ejector tube, middle ejector tube, and outer ejector tube. Gas and air in the inner ejector tube mix in the inner ring premixing chamber 103; gas and air in the middle ejector tube mix in the middle ring premixing chamber 102; and gas and air in the outer ejector tube mix in the outer ring premixing chamber 101. Gas in the inner ring premixing chamber 103 enters the inner ring gas passage 722 through the inner ring outlet 106 and is then ejected from the inner ring burner hole 721 for combustion. Gas in the middle ring premixing chamber 102 enters the second gas passage 202 of the gas distributor 20 through the middle ring outlet 105. Gas in the second gas passage 202 enters the middle ring gas passage 713 through the separating gas passage 301 and is then ejected from the middle ring burner hole 712 for combustion. The gas in the outer ring premixing chamber 101 enters the first gas passage 201 of the gas distributor 20 through the outer ring gas outlet 104, and the gas in the first gas passage 201 is directly ejected and burned through the outer ring burner hole 711. With this configuration, compared with the two-ring flame in related technologies, the gas appliance of this application has a three-ring flame, which solves the problem of the gap between the minimum and medium flame in the two-ring flame of related technologies. By placing the middle ring flame between the outer ring flame and the inner ring flame, it is beneficial to compensate for the low temperature zone between the inner and outer ring flames, ensure the temperature uniformity of the pot bottom, and improve thermal efficiency.

[0067] The burner can be transformed into three flame shapes to suit the user's cooking needs.

[0068] 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 721, the middle ring flame hole 712, and the outer ring flame hole 711. 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.

[0069] The second type of flame configuration includes an inner ring flame and a middle ring flame; that is, both the inner ring flame hole 721 and the middle ring flame hole 712 emit flame, while the outer ring flame hole 711 does not emit flame. The power range corresponding to the second type of flame configuration is 1.5kW to 2.5kW. This second type of flame configuration is suitable for frying, stewing, or other similar activities.

[0070] The third type of flame configuration includes an inner ring flame, meaning that the inner ring flame hole 721 emits flame, while the middle ring flame hole 712 and the outer ring flame hole 711 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.
