[0017] In certain embodiments, the first bracket includes a fixing plate and two groups of spring plates extending from the fixing plate, each group of the spring plates forms a corresponding slot, and the ignition needle and the thermocouple are respectively fixed in the slot.
[0018] In this way, it is ensured that the ignition needle and the thermocouple are stably arranged on the first bracket, thereby ensuring normal ignition and flameout protection of the burner assembly.
[0019] In some embodiments, the first burner includes a first lower plate, a first upper plate arranged on the first lower plate, and a first partition plate, the first lower plate is formed with a first lower channel, the first upper plate is formed with a first upper channel corresponding to the first lower channel, the first lower channel and the first upper channel are opposite to each other to form the first fire hole, and the first partition plate is arranged between the first lower plate and the first upper plate, and separates the first lower channel from the first upper channel.
[0020] In this way, the first upper channel of the first upper plate and the first lower channel of the first lower plate are arranged opposite to each other, so that the first fire holes of the first burner are formed opposite to each other, thereby increasing the total area of the fire holes of the first burner, and further increasing the flame intensity and load upper limit of the first burner.
[0021] In certain embodiments, the first separation plate is formed with a protrusion configured to contact an arc generated by the ignition needle.
[0022] In this way, the first partition plate forms a protrusion, which contacts the arc generated by the ignition needle to prevent the arc from running around, thereby increasing the ignition success rate and improving the user experience.

[0031] In certain embodiments, there is a first height difference between the first fire hole and the second fire hole, and the first height difference is in the range of (15 mm, 40 mm).
[0032] In this way, the ignition efficiency and heat dissipation efficiency of the burner assembly are improved. When the first height difference is greater than 40 mm, the first height difference is too large, so that the distance between the first burner and the second burner is too far, and it is difficult to assist the ignition of the second burner by the flame of the first burner.

[0070] See also Figures 1 to 3A burner assembly 100 provided in an embodiment of the present invention includes a first burner 10, a second burner 20 and an ignition module 30. The first burner 10 is annular and has a first fire hole 11 formed on the inner periphery. The second burner 20 is annular and has a second fire hole 21 formed on the inner periphery. The second burner 20 is arranged above the first burner 10, and the inner diameter D2 of the second burner is larger than the inner diameter D1 of the first burner. The ignition module 30 includes an ignition needle 31, a thermocouple 32 and a first bracket 33. The ignition needle 31 and the thermocouple 32 are fixed on the first bracket 33. The ignition module 30 is configured such that the ignition needle 31 is arranged close to the first fire hole 11.
[0071] In the burner assembly 100, the ignition module 30 integrates the ignition needle 31 and the thermocouple 32 so that the ignition needle 31 is close to the first fire hole 11 and is located inside the burner assembly 100, thereby improving the ignition success rate of the first burner 10 and the second burner 20, and is easy to install.
[0072] Specifically, in one embodiment, the first burner 10 may be an inner ring burner, which may be used to provide an inner ring flame to ensure the flame intensity and heating uniformity in the middle of the pot bottom.
[0073] In detail, the inner periphery of the first burner 10 is formed with a plurality of first fire holes 11 to ensure that the plurality of first fire holes 11 are surrounded by an inner ring fire outlet on the inner periphery to provide an annular inner flame to ensure uniform heating of the middle part of the pot bottom.
[0074] In one embodiment, the second burner 20 may be an outer ring burner, which may be used to provide an outer ring flame to ensure the flame intensity and heating uniformity at the edge of the pot bottom.
[0075] In detail, the inner periphery of the second burner 20 is formed with a plurality of second fire holes 21 to ensure that the plurality of second fire holes 21 are surrounded by the inner periphery to form an outer ring fire outlet, thereby providing an annular outer flame to ensure uniform heating of the edge of the pot bottom.
[0076] The inner diameter D1 of the first burner may be the diameter of the inner circumference of the first burner 10 to provide an inner ring flame with a diameter of D1.
[0077] The inner diameter D2 of the second burner may be the diameter of the inner circumference of the second burner 20 to provide an outer ring flame with a diameter of D2.
[0078] It can be understood that the inner diameter D2 of the second burner is larger than the inner diameter D1 of the first burner to ensure that the first burner 10 and the second burner 20 respectively provide inner ring flame and outer ring flame, and cooperate with each other to ensure that the middle and edge positions of the bottom of the pot are heated evenly, so that the bottom of the pot is heated evenly as a whole, thereby ensuring the uniformity of the flame of the bottom of the pot.
[0079] In one embodiment, the ignition module 30 may be used to provide a discharge arc to ensure normal ignition of the burner assembly 100 , and may also be used to detect changes in thermoelectric potential to ensure safe use of the burner assembly 100 .
[0080] In detail, the ignition needle 31 is arranged on the first bracket 33 and close to the first fire hole 11, and is used to provide a discharge arc to ignite the gas at the first fire hole 11 to form an inner ring flame. At the same time, the inner ring flame burns upward to ignite the combustion at the second fire hole 21, thereby ensuring that the burner assembly 100 is efficiently ignited, convenient and fast.
[0081] Similarly, the thermocouple 32 is spaced apart from the ignition needle 31 and fixed on the first bracket 33 to contact and detect the flame generated by the first flame hole 11 .
[0082] It can be understood that the thermocouple 32 is equivalent to a sensor, which can control the on-off of the gas passage. When the flame is accidentally extinguished due to reasons such as boiling porridge or boiling water overflowing, the thermocouple 32 can automatically cut off the gas source, thereby preventing gas leakage and playing a flameout protection role.
[0083] That is, the ignition needle 31 is arranged near the first fire hole 11 and located inside the burner assembly 100, and is used to provide a discharge arc to ignite the gas at the first fire hole 11 to form an annular inner flame. At the same time, the annular inner flame generated by the first fire hole 11 can ignite the gas at the second fire hole 21 from the inner periphery by means of flame upwards to form an annular outer flame, thereby ensuring the flame uniformity of the burner assembly 100, being convenient and fast, and having high ignition efficiency.
[0084] In one embodiment, the ignition module 30 is disposed inside the burner assembly 100 , which can reduce collisions and accidental damage caused by water overflowing from the bottom of the pot, so that the ignition module 30 can ignite normally, thereby improving the ignition success rate of the ignition module 30 .
[0085] In addition, the ignition needle 31 and the thermocouple 32 are integrated on the ignition module 30, which can ensure efficient ignition of the burner assembly 100, occupy a small space, and is easy to install.
[0086] It is worth mentioning that the first burner 10 and the second burner 20 can be stably set at an appropriate distance to ensure smooth air flow at the first fire hole 11 inside the burner assembly 100, thereby ensuring the normal operation of the first burner 10 and avoiding insufficient secondary air replenishment that causes insufficient intensity (or extinction) of the inner ring flame, thereby ensuring the overall flame uniformity of the pot bottom.
[0087] See also Figure 1 In some embodiments, the ignition module 30 is disposed between the first burner 10 and the second burner 20 .
[0088] In this way, the ignition module 30 is disposed inside the burner assembly 100 to avoid damage caused by accidental collision, thereby improving the stability and ignition efficiency of the ignition module 30.
[0089] Specifically, in one embodiment, the ignition module 30 is disposed between the first burner 10 and the second burner 20 , which can reduce the influence of the external environment on the ignition process and ensure that the ignition needle 31 works normally.
[0090] It is understandable that the external environment may be an accidental collision or accidental spillage of liquid, etc., which may cause the ignition needle 31 to be damaged and fail to ignite normally.
[0091] That is, the ignition module 30 is disposed between the first burner 10 and the second burner 20 to ensure the stability of the ignition needle 31, thereby providing a suitable ignition environment to achieve efficient ignition.
[0092] In one embodiment, the ignition module 30 can be arranged near the first fire hole 11 of the first burner 10, so that the first burner 10 can be ignited quickly to ignite the gas at the second fire hole 21 of the second burner 20 by drawing the flame upward, thereby improving the ignition success rate of the burner assembly 100.
[0093] In some embodiments, the length direction of the ignition needle 31 forms an angle α with the central axis of the first burner 10, and the range of the angle α is (30°, 90°).
[0094] In this way, the ignition needle 31 is brought close to the first fire hole 11 from above the inner periphery of the first burner 10 to ignite the gas in the first fire hole 11, thereby improving the ignition success rate.
[0095] Specifically, Figure 1 As shown, in one embodiment, the ignition needle 31 should be set at a suitable angle α to ensure that the discharge arc accurately and quickly ignites the gas in the first fire hole 11, thereby improving the ignition success rate.
[0096] In one embodiment, the angle α formed by the length direction of the ignition needle 31 and the central axis of the first burner 10 is in the range of (30°, 90°) to ensure normal ignition of the burner assembly 100.
[0097] That is, the angle α may range from (30°, 90°), that is, 30°<α<90°. In some examples, α may be 35°, 40°, 45°, 60°, 65°, 70°, 85° or other values between 30° and 90°.
[0098] When the angle α is greater than 90°, the angle α is too large, causing the end of the ignition needle 31 to tilt toward the second burner 20, resulting in an excessively large space between the first burner 10 and the second burner 20, making the distance between the first fire hole 11 and the second fire hole 21 farther, that is, the inner ring flame generated by the first fire hole 11 is less effective in igniting the gas at the second fire hole 21, resulting in poor ignition efficiency.
[0099] In addition, the distance between the inner ring flame and the bottom of the pot is quite different from the distance between the outer ring flame and the bottom of the pot, which makes the flame intensity at the bottom of the pot inconsistent, thereby reducing the flame uniformity.
[0100] When the angle α is less than 30°, the angle α is too small, causing the tip of the ignition needle 31 to deviate from the first fire hole 11 and be set upward, so that the arc generated by the ignition needle 31 is too far away from the first fire hole 11, and it is not easy to lead the arc to the first fire hole 11, thereby reducing the ignition success rate.
[0101] In some embodiments, the length direction of the ignition needle 31 forms an angle α with the central axis of the first burner 10, and the range of the angle α is (60°, 70°).
[0102] In this way, the positions of the ignition needle 31 and the first fire hole 11 are ensured to be more suitable, so that the ignition success rate of the first burner 10 is higher.
[0103] Specifically, Figure 1 As shown, in one embodiment, preferably, the angle α formed by the length direction of the ignition needle 31 and the central axis of the first burner 10 is in the range of (60°, 70°), so that the ignition success rate of the ignition needle 31 is high, thereby ensuring fast and efficient ignition of the first burner 10.
[0104] That is, the angle α may range from (60°, 70°), that is, 60°<α<70°. In some examples, α may be 61°, 63°, 64°, 65°, 67°, 68°, 69° or other values between 60° and 70°.
[0105] When the angle α is greater than 70°, the angle α is larger, so that the space between the first burner 10 and the second burner 20 is larger, resulting in a longer distance between the first fire hole 11 and the second fire hole 21, that is, the inner ring flame generated by the first fire hole 11 is less effective in igniting the gas at the second fire hole 21, resulting in poor ignition efficiency.
[0106] In addition, the distance between the inner ring flame and the bottom of the pot is quite different from the distance between the outer ring flame and the bottom of the pot, which makes the flame intensity at the bottom of the pot inconsistent, thereby reducing the flame uniformity.
[0107] When the angle α is less than 60°, the angle α is small, so that the tip of the ignition needle 31 deviates from the first fire hole 11 and is set upward, so that the arc generated by the ignition needle 31 is far away from the first fire hole 11, and it is not easy to lead the arc to the first fire hole 11, thereby reducing the ignition success rate.
[0108] See also Figure 3 In some embodiments, the ignition module 30 is disposed inside the first burner 10 .
[0109] In this way, the ignition needle 31 is moved closer to the first fire hole 11 from below the inner periphery of the first burner 10 to ignite the gas in the first fire hole 11, thereby improving the ignition success rate.
[0110] Specifically, Figure 3 As shown, in one embodiment, the ignition module 30 is arranged on the inner side of the first burner 10, that is, the ignition module 30 is close to the first fire hole 11 from the bottom of the inner periphery of the first burner 10, which can reduce the impact of accidental collision or accidental spillage of liquid on the ignition process, thereby ensuring the normal operation of the ignition needle 31.
[0111] That is, the ignition module 30 is disposed inside the first burner 10 to improve the stability of the ignition needle 31 , thereby providing a stable ignition environment to achieve efficient ignition.
[0112] In one embodiment, the ignition module 30 is arranged near the first fire hole 11 of the first burner 10, so that the first burner 10 ignites quickly to ignite the gas at the second fire hole 21 of the second burner 20 by drawing the flame upward, thereby improving the ignition success rate of the burner assembly 100.
[0113] In one embodiment, the ignition module 30 is disposed inside the first burner 10 , so that the appearance of the burner assembly 100 is more beautiful and neat.
[0114] See also Figure 2 In some embodiments, the first bracket 33 includes a fixing plate 331 and two groups of spring plates 332 extending from the fixing plate 331 , each group of spring plates 332 forms a corresponding slot 333 , and the ignition needle 31 and the thermocouple 32 are respectively fixed in the slot 333 .
[0115] In this way, it is ensured that the ignition needle 31 and the thermocouple 32 are stably arranged on the first bracket 33, thereby ensuring normal ignition and flameout protection of the burner assembly 100.
[0116] Specifically, in one embodiment, the fixing plate 331 may be a supporting base plate for supporting and fixing the ignition needle 31 and the thermocouple 32 to improve the stability of the ignition module 30 .
[0117] In one embodiment, the spring piece 332 may be two arc-shaped metal sheets to form a clamping slot 333 , which can ensure that the ignition needle 31 and the thermocouple 32 are respectively clamped in the slot 333 , thereby improving the stability of the ignition module 30 .
[0118] It can be understood that the spring piece 332 is set on the bracket 22 at a certain angle so that the tip of the ignition needle 31 and the tip of the thermocouple 32 are set close to each other, and the end of the ignition needle 31 and the end of the thermocouple 32 are set far away from each other, thereby ensuring that the ignition needle 31 and the thermocouple 32 are close to the first fire hole 11, thereby ensuring normal ignition and flameout protection of the burner assembly 100.
[0119] In addition, the ignition needle 31 and the thermocouple 32 are integrated on the first bracket 33 to improve installation efficiency, while ensuring efficient ignition and flameout protection of the burner assembly 100, thereby improving the safety of the burner assembly 100.
[0120] See also Figure 4 In some embodiments, the first burner 10 includes a first lower plate 12, a first upper plate 13 and a first partition plate 14 arranged on the first lower plate 12, the first lower plate 12 is formed with a first lower channel 121, the first upper plate 13 is formed with a first upper channel 131 corresponding to the first lower channel 121, the first lower channel 121 and the first upper channel 131 are opposite to form a first fire hole 11, and the first partition plate 14 is arranged between the first lower plate 12 and the first upper plate 13, and separates the first lower channel 121 from the first upper channel 131.
[0121] In this way, the first upper channel 131 of the first upper plate 13 and the first lower channel 121 of the first lower plate 12 are arranged opposite to each other, so that the first fire hole 11 of the first burner 10 is formed opposite to each other, thereby increasing the total area of the fire hole of the first burner 10, and further increasing the flame intensity and load upper limit of the first burner 10.
[0122] Specifically, the first lower plate 12 can be used to form the first fire hole 11, so the first lower plate 12 can be made of a high temperature resistant and corrosion resistant material.
[0123] In one embodiment, the first lower plate 12 may be made of aluminum alloy to ensure the bending performance of the first lower plate 12, thereby ensuring the concave shape of the first lower channel 121. In other embodiments, the first lower plate 12 may also be made of other materials, which are not specifically limited here.
[0124] Similarly, the first upper plate 13 can be used to form the first fire hole 11 with the first lower plate 12, so the first upper plate 13 can be made of a high temperature resistant and corrosion resistant material.
[0125] In one embodiment, the first upper plate 13 can be made of the same material as the first lower plate 12 to ensure the bending performance of the first upper plate 13, thereby ensuring the upward convexity of the first upper channel 131. In other embodiments, the first upper plate 13 can also be made of other materials, which are not specifically limited here.
[0126] It can be understood that the first lower channel 121 and the first upper channel 131 are formed opposite to each other to form a first fire hole 11 similar to a circular ring. Compared with a single first lower channel 121 or a single first upper channel 131 arranged in a staggered manner, the total area of the first fire hole 11 is increased, so that the combustion amount of the gas is increased, thereby improving the flame intensity of the first burner 10.
[0127] In addition, compared with the burner without the first partition plate 14, the equivalent cross-sectional area of the first fire hole 11 of the present application does not change, which can ensure that the first burner 10 has a larger flame and excellent fire transfer and flame stabilization effects.
[0128] In certain embodiments, the first partition plate 14 is formed with a protrusion 141 configured to contact the arc generated by the ignition needle 31 .
[0129] In this way, the first partition plate 14 forms a protrusion 141, which contacts the arc generated by the ignition needle 31 to prevent the arc from running away, thereby increasing the ignition success rate and improving the user experience.
[0130] Specifically, the protrusion 141 is arranged on the first partition plate 14, and can be used to attract the arc generated by the ignition needle 31, so that the arc ignites the gas at the protrusion 141 to form a flame, so as to prevent the discharge arc of the ignition needle 31 from deviating from the direction of the first partition plate 14, thereby improving the ignition success rate of the first burner 10.
[0131] It can be understood that the first upper plate 13 and the first partition plate 14 form a first fire transfer gap 15 between two adjacent first upper channels 131. When the arc generated by the ignition needle 31 contacts the protrusion 141, the efficiency of the first fire hole 11 in forming an overall annular flame can be improved, thereby improving the ignition success rate of the first burner 10 and further ensuring the ignition efficiency of the burner assembly 100.
[0132] In some embodiments, the second burner includes a second lower plate 22, a second upper plate 23 and a second partition plate 24 disposed on the second lower plate 22, the second lower plate 22 is formed with a second lower channel 221, the second upper plate 23 is formed with a second upper channel 231 corresponding to the second lower channel 221, the second lower channel 221 and the second upper channel 231 are opposite to form a second fire hole 21, and the second partition plate 24 is disposed between the second lower plate 22 and the second upper plate 23, and separates the second lower channel 221 from the second upper channel 231.
[0133] In this way, the second upper channel 231 of the second upper plate 23 and the second lower channel 221 of the second lower plate 22 are arranged opposite to each other, so that the second fire holes 21 of the second burner 20 are formed opposite to each other, thereby increasing the total area of the fire holes of the second burner 20, and further increasing the flame intensity and load upper limit of the second burner 20.
[0134] Specifically, in one embodiment, the second lower plate 22 may be used to form the second fire hole 21 , and thus the second lower plate 22 may be made of a high temperature resistant and corrosion resistant material.
[0135] In one embodiment, the second lower plate 22 may be made of aluminum alloy to ensure the bending performance of the second lower plate 22, thereby ensuring the forming of the second lower channel 221. In other embodiments, the second lower plate 22 may also be made of other materials, which are not specifically limited here.
[0136] Similarly, the second upper plate 23 can be used to form the second fire hole 21 with the second lower plate 22, so the second upper plate 23 can be made of a high temperature resistant and corrosion resistant material.
[0137] In one embodiment, the second upper plate 23 can be made of the same material as the second lower plate 22 to ensure the bending performance of the second upper plate 23, thereby ensuring the forming of the second upper channel 231. In other embodiments, the second upper plate 23 can also be made of other materials, which are not specifically limited here.
[0138] It can be understood that the second lower channel 221 and the second upper channel 231 are formed opposite to each other to form a second fire hole 21 similar to a circular ring. Compared with a single second lower channel 221 or a single second upper channel 231 arranged in a staggered manner, the total area of the second fire hole 21 is increased, so that the combustion amount of the gas is increased, thereby improving the flame intensity of the second burner 20.
[0139] In addition, compared with the burner without the second partition plate 24, the equivalent cross-sectional area of the second fire hole 21 of the present application does not change, which can ensure that the second burner 20 has a larger flame and excellent flame transfer and flame stabilization effects.
[0140] See also Figure 1 , Figure 5 and Figure 6 In certain embodiments, the inner diameter D2 of the second burner is 1.2 to 2.5 times the inner diameter D1 of the first burner.
[0141] In this way, it is ensured that the flame generated by the burner assembly 100 can better cover the bottom of the pot, thereby improving the cooking efficiency.
[0142] Specifically, in one embodiment, the inner diameter D1 of the first burner may be set to ensure that the annular flame generated by the first burner 10 can be better located in the middle of the pot bottom to increase the flame intensity in the middle of the pot bottom and ensure that the middle of the pot bottom is heated evenly.
[0143] In one embodiment, the inner diameter D2 of the second burner is 1.2 to 2.5 times the inner diameter D1 of the first burner to ensure that the flame generated by the burner assembly 100 heats the bottom of the pot evenly, thereby improving gas utilization and cooking efficiency.
[0144] It can be understood that when the inner diameter of the first burner 10 is D1, the inner diameter D2 of the second burner can be in the range of (1.2D1, 2.5D1), so that the flame generated by the second burner 20 can better cover the edge of the bottom of the pot, thereby ensuring that the middle and edge of the bottom of the pot are evenly heated, thereby improving cooking efficiency.
[0145] That is, the inner diameter D2 of the second burner is in the range of 2.5D1>D2>1.2D1. In some examples, the inner diameter D2 of the second burner may be 1.3D1, 1.5D1, 1.6D1, 1.9D1, 2.0D1, 2.3D1, 2.4D1 or other values between 1.2D1 and 2.5D1.
[0146] When the inner diameter D2 of the second burner is greater than 2.5D1, the inner diameter D2 of the second burner is too large, causing the outer ring flame generated by the second fire hole 21 to extend to the outside of the pot bottom, resulting in a large distance between the outer ring flame and the inner ring flame at the pot bottom, insufficient heating, and reduced flame uniformity of the burner assembly 100.
[0147] In addition, the outward extension of the gas reduces the utilization rate of the gas, and there is also a risk of high temperature of the pot handle causing scalding to the user.
[0148] When the inner diameter D2 of the second burner is less than 1.2D1, the inner diameter D2 of the second burner is too small, so that the outer ring flame generated by the second fire hole 21 is close to the inner ring flame generated by the first fire hole 11, resulting in excessive heating of the middle part of the bottom of the pot and insufficient heating of the edge of the bottom of the pot, making the overall bottom of the pot heated unevenly, which may easily cause safety risks.
[0149] In certain embodiments, the inner diameter D2 of the second burner is 1.5 times the inner diameter D1 of the first burner.
[0150] In this way, by adjusting the appropriate flame position, the heating area of the pot bottom and the cooking efficiency can be further improved while ensuring that the flame covers the pot bottom well.
[0151] Specifically, in one embodiment, the inner diameter D2 of the second burner is 1.5 times the inner diameter D1 of the first burner, so that the inner ring flame generated by the first fire hole 11 and the outer ring flame generated by the second fire hole 21 are located at appropriate positions on the bottom of the pot, thereby better ensuring the heat supply and flame uniformity of the bottom of the pot.
[0152] It can be understood that the inner diameter D2 of the second burner can be D2=1.5D1, so that the outer ring flame generated by the second burner 20 just wraps the edge of the bottom of the pot while ensuring that the inner ring flame generated by the first burner 10 is located in the middle of the bottom of the pot, thereby improving the flame uniformity of the burner assembly 100 and further improving the gas utilization efficiency and cooking efficiency.
[0153] In one embodiment, for example, the inner diameter D1 of the first burner is 80 mm, and it can be seen from D2=1.5D1 that the inner diameter D2 of the second burner is 120 mm, so as to ensure that the flame generated by the burner assembly 100 better covers the bottom of the pot, thereby ensuring the uniformity and intensity of the flame, so as to improve the cooking efficiency and gas utilization.
[0154] In other embodiments, the inner diameter D1 of the first burner may also be other values, as long as D2=1.5D1 is ensured, and no specific limitation is made here.
[0155] See also Figure 2 , Figure 7 and Figure 8 In some embodiments, the burner assembly 100 includes a second bracket 40 , the first bracket 33 is formed with a fixing hole 334 , and the ignition module 30 is mounted on the second bracket 40 through the fixing hole 334 .
[0156] In this way, while ensuring that the ignition module 30 is stably disposed on the second bracket 40 , the ignition needle 31 is directed toward and close to the protrusion 141 , thereby ensuring ignition efficiency.
[0157] Specifically, please combine Figure 7 In one embodiment, the burner assembly 100 further includes an oil cup 60 and a fixing plate 70 .
[0158] In one embodiment, the oil cup 60 can be used to hold oil drops flowing down the guide plate 50 during the cooking process to improve the cleanliness of the kitchen, thereby improving the user experience.
[0159] In one embodiment, the fixing plate 70 is disposed above the second burner 20 and can be used to fix the second burner 20 to improve the stability and safety of the burner assembly 100 .
[0160] In one embodiment, the second bracket 40 may be a burner bracket, and the ignition module 30 may be stably disposed on the second bracket by means of screws engaging the fixing holes 334 , thereby improving the stability of the ignition needle 31 and the ignition success rate.
[0161] In one embodiment, the second bracket 40 may be disposed at the bottom of the burner assembly 100 , and the second bracket 40 is formed with a cylindrical inner cavity, which can be used to hold the oil cup 60 to ensure that the burner assembly 100 is clean and sanitary.
[0162] In one embodiment, the second bracket 40 is also formed with a plurality of claws, and the plurality of claws are formed with a plurality of mounting holes, which can be used to fix and support the ignition module 30 and the burner assembly 100, thereby ensuring the stable operation of the burner assembly 100 and improving the safety of kitchen cooking.
[0163] In addition, the second bracket 40 can be used to fix multiple components, such as the ignition module 30 , the oil cup 60 , and the fixing plate 70 , so as to improve the installation efficiency of the burner assembly 100 .
[0164] In one embodiment, the second bracket 40 may be integrally formed by die-casting of an aluminum alloy material to reduce weight and production costs, or may be formed by other processes, which are not specifically limited herein.
[0165] In one embodiment, the first bracket 33 can be used to support the ignition module 30 to improve the stability of the ignition module 30. In addition, the fixing hole 334 formed by the first bracket 33 has a limiting function, so that the ignition needle 31 faces and approaches the protrusion 141, thereby improving the ignition success rate.
[0166] See also Figure 1 In some embodiments, there is a first height difference H1 between the first fire hole 11 and the second fire hole 21, and the range of the first height difference H1 is (15 mm, 40 mm).
[0167] In this way, the ignition efficiency and heat dissipation efficiency of the burner assembly 100 are improved. When the first height difference H1 is greater than 40 mm, the first height difference H1 is too large, so that the distance between the first burner 10 and the second burner 20 is too far, and it is difficult to assist the ignition of the second burner 20 by the flame of the first burner 10. When the first height difference H1 is less than 15 mm, the first height difference H1 is too small, so that the distance between the first burner 10 and the second burner 20 is too close, and the heat dissipation effect is poor, so that the internal heat of the burner assembly 100 is too high, which is easy to cause safety hazards.
[0168] Specifically, in one embodiment, the first height difference H1 should be selected to have a suitable distance to ensure the normal operation and safe use of the first burner 10 and the second burner 20 .
[0169] In one embodiment, the first height difference H1 may be in the range of (15 mm, 40 mm) to ensure the heat dissipation efficiency and flame transfer efficiency of the burner assembly 100 , thereby improving the safety of the burner assembly 100 .
[0170] That is, the first height difference H1 may be in the range of (15 mm, 40 mm), that is, 15 mm < H1 < 40 mm. In some examples, H1 may be 17 mm, 19 mm, 23 mm, 25 mm, 30 mm, 32 mm, 37 mm, or other values between 15 mm and 40 mm.
[0171] When the first height difference H1 is greater than 40 mm, the first height difference H1 is too large, so that the distance between the first burner 10 and the second burner 20 is too far, and it is difficult to assist the ignition of the second burner 20 by the flame of the first burner 10, thereby reducing the ignition efficiency.
[0172] When the first height difference H1 is less than 15 mm, the first height difference H1 is too small, so that the distance between the first burner 10 and the second burner 20 is too close, the heat dissipation effect is poor, and the internal heat of the burner assembly 100 is too high, which is prone to safety hazards.
[0173] In some embodiments, there is a first height difference H1 between the first fire hole 11 and the second fire hole 21 , and the first height difference H1 is in the range of (20 mm, 30 mm).
[0174] In this way, the ignition efficiency and heat dissipation efficiency of the burner assembly 100 are further improved. When the first height difference H1 is greater than 30 mm, the first height difference H1 is large, so that the distance between the first burner 10 and the second burner 20 is relatively far, and the ignition efficiency of the second burner 20 assisted by the flame of the first burner 10 is relatively low. When the first height difference H1 is less than 20 mm, the first height difference H1 is small, so that the distance between the first burner 10 and the second burner 20 is relatively close, and the heat dissipation effect is poor, so that the internal heat of the burner assembly 100 is relatively high, which is prone to safety hazards.
[0175] Specifically, in one embodiment, the first height difference H1 should be selected to have a suitable distance to ensure the normal operation and safe use of the first burner 10 and the second burner 20 .
[0176] In one embodiment, preferably, the first height difference H1 may be in the range of (20 mm, 30 mm) to further improve the heat dissipation efficiency and flame transfer efficiency of the burner assembly 100 .
[0177] That is, the first height difference H1 may be in the range of (20 mm, 30 mm), that is, 20 mm < H1 < 30 mm. In some examples, H1 may be 21 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 29 mm, or other values between 20 mm and 30 mm.
[0178] When the first height difference H1 is greater than 30 mm, the first height difference H1 is relatively large, so that the distance between the first burner 10 and the second burner 20 is relatively far, and the ignition efficiency of the second burner 20 assisted by the flame of the first burner 10 is relatively low.
[0179] When the first height difference H1 is less than 20 mm, the first height difference H1 is small, so that the distance between the first burner 10 and the second burner 20 is close, the heat dissipation effect is poor, and the internal heat of the burner assembly 100 is high, which is prone to safety hazards.
[0180] In some embodiments, there is a first height difference H1 between the first fire hole 11 and the second fire hole 21 , and the first height difference H1 is 23.65 mm.
[0181] In this way, the ignition efficiency and heat dissipation efficiency of the burner assembly 100 are high, thereby ensuring the safety of the burner assembly 100 .
[0182] Specifically, in one embodiment, preferably, the first height difference H1 can be 23.65 mm, that is, the distance between the first fire hole 11 and the second fire hole 21 is 23.65 mm. Under the condition of ensuring that there is a suitable heat dissipation space between the first burner 10 and the second burner 20, the first fire hole 11 can quickly assist the ignition of the second fire hole 21 by drawing the flame upward, thereby improving the ignition efficiency and heat dissipation efficiency of the burner assembly 100.
[0183] It can be understood that when the first height difference H1 is 23.65 mm, the flame generated by the first burner 10 is transmitted from the first fire hole 11 to the second fire hole 21 (from bottom to top), and the gas at the second fire hole 21 can be better ignited from the inner periphery of the second burner 20 to form a double-ring flame to cover the bottom of the pot, thereby improving the ignition efficiency.
[0184] In addition, when the first height difference H1 is 23.65 mm, the heat dissipation space between the first burner 10 and the second burner 20 is appropriate, which can ensure that the air can flow smoothly in the burner assembly 100, that is, the internal heat of the burner assembly 100 can be removed by air cooling, thereby improving the heat dissipation efficiency and ensuring the safe operation of the burner assembly 100.
[0185] See also Figure 4 and Figure 7In some embodiments, the burner assembly 100 includes a guide plate 50, which is disposed between the first burner 10 and the second burner 20. There is a second height difference H2 between the guide plate 50 and the top of the first fire hole 11, and there is a third height difference H3 between the guide plate 50 and the bottom of the second fire hole 21. The third height difference H3 is greater than the second height difference H2.
[0186] In this way, the first burner 10 and the second burner 20 are respectively kept at a suitable distance from the guide plate 50 to improve the air flow inside the burner assembly 100 , thereby improving the combustion efficiency of the burner assembly 100 .
[0187] Specifically, in one embodiment, the guide plate 50 is arranged in a funnel shape between the first burner 10 and the second burner 20, and the end with a larger opening is arranged near the bottom of the second fire hole 21, and the end with a smaller opening is arranged near the top of the first fire hole 11, so as to increase the space between the first burner 10 and the second burner 20 and ensure the supply of secondary air, thereby improving the combustion efficiency of the burner assembly 100.
[0188] In one embodiment, the second height difference H2 may be the distance between the guide plate 50 and the top of the first fire hole 11 . The second height difference H2 should be selected to be a smaller distance so that the secondary air reaches the first fire hole 11 faster, thereby ensuring the combustion efficiency of the first burner 10 .
[0189] In one embodiment, the third height difference H3 may be the distance between the guide plate 50 and the bottom of the second fire hole 21 . A larger spacing should be selected for the third height difference H3 to ensure that secondary air quickly passes into the interior of the burner assembly 100 from multiple paths, thereby improving the combustion efficiency of the burner assembly 100 .
[0190] It can be understood that the third height difference H3 is greater than the second height difference H2, ensuring that the distance between the guide plate 50 and the bottom of the second fire hole 21 is large, so that the secondary air can enter the burner assembly 100 faster and provide sufficient secondary air for the burner assembly 100.
[0191] In addition, the third height difference H3 is greater than the second height difference H2, ensuring that the distance between the guide plate 50 and the top of the first fire hole 11 is small, so that the secondary air inside the burner assembly 100 is transported at a shorter distance and a faster speed, thereby improving the combustion efficiency of the burner assembly 100.
[0192] It is worth noting that the guide plate 50 is arranged in a funnel shape between the first burner 10 and the second burner 20, and can also be used to flow oil droplets generated during the cooking process into the oil cup 60 along the side wall of the guide plate 50 to improve the cleanliness of the burner assembly 100.
[0193] In one embodiment, the guide plate 50 is arranged in a funnel shape between the first burner 10 and the second burner 20, and can also be used to shield the internal structure of the burner assembly 100, so that the burner assembly 100 is beautiful and neat.
[0194] See also Figure 4 In some embodiments, the second height difference H2 is in the range of (0, 8 mm).
[0195] In this way, the top of the first burner 10 is kept at a suitable distance from the guide plate 50 to improve the supply of secondary air, thereby improving the combustion efficiency of the first burner 10 .
[0196] Specifically, in one embodiment, the second height difference H2 should be selected to have a suitable distance to ensure the supply speed of the secondary air of the first fire hole 11 , thereby improving the combustion efficiency of the first burner 10 .
[0197] In one embodiment, the second height difference H2 may be in the range of (0, 8 mm) so as to provide sufficient secondary air in time to ensure that the gas at the first fire hole 11 is fully burned, thereby improving the combustion efficiency of the first burner 10 .
[0198] That is, the second height difference H2 may be in the range of (0, 8 mm), that is, 0<H2<8 mm. In some examples, H2 may be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm or other values between 0 and 8 mm.
[0199] When the second height difference H2 is greater than 8 mm, the second height difference H2 is too large, so that the time for the secondary air to reach the first fire hole 11 is too long, thereby reducing the combustion efficiency of the first burner 10 and the flame uniformity is low.
[0200] In certain embodiments, the second height difference H2 is 5 mm.
[0201] In this way, while ensuring that there is an appropriate distance between the top of the first burner 10 and the guide plate 50, the supply of secondary air is sufficient, so that the combustion efficiency of the first burner 10 is higher.
[0202] Specifically, in one embodiment, preferably, the second height difference H2 can be 5 mm, that is, the distance between the top of the first fire hole 11 and the guide plate 50 is 5 mm. While ensuring that there is an appropriate distance between the top of the first burner 10 and the guide plate 50, the secondary air can quickly reach the first fire hole 11, thereby making the combustion efficiency of the first burner 10 higher.
[0203] It can be understood that when the second height difference H2 is 5 mm, the gas at the first fire hole 11 can be fully burned by the secondary air, so that the combustion efficiency of the first burner 10 is higher, thereby improving the flame intensity.
[0204] In addition, when the second height difference H2 is 5 mm, the distance between the first burner 10 and the guide plate 50 is large, and the heat dissipation efficiency is high, thereby ensuring the safe operation of the burner assembly 100.
[0205] In certain embodiments, the third height difference H3 is in the range of (0, 15 mm).
[0206] In this way, the bottom of the second burner 20 is kept at a suitable distance from the guide plate 50 to improve the supply of secondary air, thereby improving the combustion efficiency and ensuring the flame uniformity of the burner assembly 100.
[0207] Specifically, in one embodiment, the third height difference H3 should be selected to have a suitable distance so that sufficient secondary air can be introduced into the burner assembly 100 while ensuring full combustion of the gas in the second fire hole 21 , thereby ensuring flame uniformity of the burner assembly 100 .
[0208] In one embodiment, the third height difference H3 may be in the range of (0, 15 mm), that is, 0<H3<15 mm. In some examples, H3 may be 1 mm, 3 mm, 4 mm, 7 mm, 9 mm, 10 mm, 13 mm or other values between 0 and 15 mm.
[0209] When the third height difference H3 is greater than 15 mm, the third height difference H3 is too large, so that the distance between the guide plate 50 and the second fire hole 21 is too large, the stability is reduced, and it is difficult to fix.
[0210] In addition, the third height difference H3 is too large, which makes the burner assembly 100 larger in volume and occupies a larger space.
[0211] In certain embodiments, the third height difference H3 is 9 mm.
[0212] In this way, while ensuring that there is an appropriate distance between the bottom of the second burner 20 and the guide plate 50, the supply of secondary air is sufficient, so that the combustion efficiency of the burner assembly 100 is higher and the flame uniformity is better.
[0213] Specifically, in one embodiment, preferably, the third height difference H3 can be 9 mm, that is, the distance between the bottom of the second fire hole 21 and the guide plate 50 is 9 mm. Under the condition of ensuring that the gas in the second fire hole 21 is fully burned, sufficient secondary air can be introduced into the burner assembly 100, so that the combustion efficiency of the first burner 10 is higher, thereby ensuring that the flame uniformity of the burner assembly 100 is better.
[0214] It can be understood that when the third height difference H3 is 9 mm, the gas at the second fire hole 21 can be fully burned by the secondary air, so that the combustion efficiency of the second burner 20 is higher, thereby improving the flame intensity.
[0215] In addition, when the third height difference H3 is 9 mm, sufficient secondary air can quickly enter the burner assembly 100 through the third height difference H3 to accelerate air flow and heat dissipation rate. At the same time, sufficient secondary air can also reach the first fire hole 11 along the side wall of the guide plate 50 to fully burn the gas in the first fire hole 11, thereby ensuring that the burner assembly 100 has high combustion efficiency and good flame uniformity.
[0216] In some embodiments, a first fire transfer gap 15 is formed between the first upper plate 13 and the first partition plate 14 , and the first fire transfer gap 15 communicates with two adjacent first fire holes 11 .
[0217] In this way, two adjacent independent first flame holes 11 are connected together, thereby ensuring the formation of an integral flame, thereby improving the flame transfer capability and anti-fire-out capability of the first burner 10 .
[0218] Specifically, in one embodiment, the first flame transfer gap 15 is formed between the first upper plate 13 and the first partition plate 14 to ensure that a connectable gap is formed between two adjacent first upper channels 131 in the first upper plate 13 to play a role in transferring and stabilizing the flame.
[0219] It can be understood that during the ignition process of the first burner 10, the ignition needle 31 can release an electric arc to the protrusion 141 to ignite the gas at the outlet of one of the first upper channels 131, and transfer the flame to two adjacent first upper channels 131 through the first flame transfer gap 15, thereby forming a continuous flame, thereby ensuring the flame transfer efficiency and ignition success rate.
[0220] During the continuous operation of the first burner 10, the first fire transfer gap 15 connects the two adjacent first upper channels 131 and continuously replenishes secondary air to ensure that the gas in the two adjacent first upper channels 131 is fully burned, so that the first burner 10 forms an overall continuous flame, thereby ensuring high flame intensity and good stability, thereby improving the anti-fire capability of the first burner 10 and achieving the purpose of flame stabilization.
[0221] In one embodiment, the range of the first flame transfer gap 15 can be [0.50 mm, 0.80 mm], so that two adjacent independent first upper channels 131 are connected together to ensure the flame transfer capability and flame stabilization capability of the first burner 10 .
[0222] That is, the first ignition gap 15 ranges from 0.50 mm to 0.80 mm. In some examples, the first ignition gap 15 can be 0.50 mm, 0.57 mm, 0.62 mm, 0.68 mm, 0.70 mm, 0.71 mm, 0.80 mm or other values between 0.50 mm and 0.80 mm.
[0223] When the first flame transfer gap 15 is less than 0.50 mm, the first flame transfer gap 15 is too small, the flame transfer efficiency and the secondary air supplement efficiency are low, so that the flame transfer ability of the first burner 10 is poor.
[0224] When the first flame transfer gap 15 is larger than 0.80 mm, the first flame transfer gap 15 is too large, the flame stability is low, and the flameout resistance of the first burner 10 is poor, and flameout and extinguishing phenomenon is easy to occur.
[0225] In some embodiments, a second fire transfer gap 25 is formed between the second upper plate 23 and the second partition plate 24 , and the second fire transfer gap 25 communicates with two adjacent second fire holes 21 .
[0226] In this way, two adjacent independent second flame holes 21 are connected together, thereby ensuring the formation of an integral flame, thereby improving the flame transfer capability and anti-fire-out capability of the second burner 20 .
[0227] Specifically, in one embodiment, the second flame transfer gap 25 is formed between the second upper plate 23 and the second partition plate 24 to ensure that a connectable gap is formed between two adjacent second upper channels 231 in the second upper plate 23 to play a role in transferring and stabilizing the flame.
[0228] It can be understood that the second burner 20 can be ignited by the flame generated by the first burner 10 to ignite the gas at the second fire hole 21, and transfer the flame to the two adjacent second upper channels 231 through the second fire transfer gap 25, thereby forming a continuous flame, thereby ensuring the fire transfer efficiency and ignition success rate.
[0229] During the continuous operation of the second burner 20, the second fire transfer gap 25 connects the two adjacent second upper channels 231 and continuously replenishes secondary air to ensure that the gas in the two adjacent second upper channels 231 is fully burned, so that the second burner 20 forms an overall continuous flame, thereby ensuring high flame intensity and good stability, thereby improving the second burner 20's anti-fire ability and achieving the purpose of flame stabilization.
[0230] In one embodiment, the second flame transfer gap 25 may be in the range of [0.50 mm, 0.80 mm], so that two adjacent independent second upper channels 231 are connected together to ensure the flame transfer capability and flame stabilization capability of the second burner 20 .
[0231] That is, the second ignition gap 25 ranges from 0.50 mm to 0.80 mm. In some examples, the second ignition gap 25 can be 0.50 mm, 0.57 mm, 0.62 mm, 0.68 mm, 0.70 mm, 0.71 mm, 0.80 mm or other values between 0.50 mm and 0.80 mm.
[0232] When the second flame transfer gap 25 is less than 0.50 mm, the second flame transfer gap 25 is too small, the flame transfer efficiency and the secondary air supplement efficiency are low, so that the flame transfer ability of the second burner 20 is poor.
[0233] When the second flame transfer gap 25 is larger than 0.80 mm, the second flame transfer gap 25 is too large, the flame stability is low, and the flameout resistance of the second burner 20 is poor, which easily causes flameout and extinguishing.

[0235] In the stove 1000, the ignition module 30 integrates the ignition needle 31 and the thermocouple 32 so that the ignition needle 31 is close to the first fire hole 11 and is located inside the burner assembly 100, thereby improving the ignition success rate of the first burner 10 and the second burner 20, and is easy to install.
