Abstract
Description
Technical Field
[0001] This invention relates to the field of kitchen appliance technology, and in particular to a burner, burner assembly, and stove. Background Technology
[0002] In order to obtain a larger flame, the burner's flame holes are generally set to be relatively large, resulting in a larger cross-sectional area. However, the depth of the flame holes is relatively insufficient. Therefore, the flame can easily enter the gas passage through the flame holes and burn at the moment the gas valve is closed, causing phenomena such as flameout noise. Summary of the Invention
[0003] The present invention provides a burner, a burner assembly, and a stove.
[0004] This invention provides a burner, the burner comprising:
[0005] Lower board;
[0006] An upper plate is disposed on the lower plate, the lower plate having a lower channel and the upper plate having an upper channel; and
[0007] A partition plate is disposed between the lower plate and the upper plate, and separates the lower channel from the upper channel.
[0008] The burner in this embodiment uses a partition plate to separate the lower and upper channels, effectively dividing them into two independent sub-flame holes. The cross-sectional area of each sub-flame hole is reduced, thus increasing its depth. This prevents the flame from entering the gas passage through the sub-flame hole and causing flameout noise at the moment the gas valve is closed. Furthermore, the equivalent cross-sectional area formed by the lower and upper channels remains unchanged, ensuring a larger flame in the burner.
[0009] In some embodiments, the partition plate includes a partition plate body located between the lower plate and the upper plate, the partition plate body being substantially annular, and the partition plate further includes a flange bent from the outer peripheral edge of the partition plate body toward the lower plate.
[0010] In this way, the flange bends towards the lower plate to block the gas from entering the lower and upper channels corresponding to the flange through the gas passage, thereby reducing the gas output of the lower and upper channels corresponding to the flange, and thus reducing the flame length of the lower and upper channels corresponding to the flange, so as to ensure the uniformity of the flame in the lower and upper channels.
[0011] In some embodiments, the arc angle of the flange is from 0 degrees to 180 degrees.
[0012] Thus, by setting a flange with a certain arc angle on the partition plate to adjust the flame length of the lower and upper channels, the uniformity of the flame in the lower and upper channels can be ensured.
[0013] In some embodiments, the arc angle of the flange is between 0 and 150 degrees.
[0014] This allows for more precise adjustment of the flame length in the lower and upper channels, thereby ensuring the uniformity of the flame in the lower and upper channels.
[0015] In some embodiments, the lower plate includes a lower plate body, and the upper plate includes an upper plate body. The lower plate body and the upper plate body are substantially annular. Multiple lower channels are distributed along the inner circumference of the lower plate body, and multiple upper channels are distributed along the inner circumference of the upper plate body. The lower plate includes a lower ejector tube connected to the lower plate body, and the lower ejector tube forms a lower ejector conduit. The lower plate body forms a lower air passage connecting the lower ejector conduit and the lower channels. The upper plate includes a lower air passage connected to the upper plate body. The upper ejector tube is connected to the upper ejector tube section, which forms an upper ejector conduit. The upper plate body forms an upper air passage connecting the upper ejector conduit and the upper channel. The lower ejector tube section cooperates with the upper ejector tube section to form the ejector tube of the burner. The lower air passage and the upper air passage cooperate to form the air passage of the burner. The ejector tube is connected to the air passage to form the ejector tube outlet. The diameter of the upper channel and the lower channel away from the ejector tube outlet is larger than the diameter of the upper channel and the lower channel near the ejector tube outlet.
[0016] This design allows the flame generated by the interaction of the lower and upper channels to converge, while simultaneously enhancing the flame's coverage of the pot bottom and improving combustion efficiency. Furthermore, the aperture sizes of the lower and upper channels gradually decrease from the position furthest from the ejector tube outlet to the position closest to the outlet, ensuring that the combustion gas flowing through the lower and upper channels, even those far from the ejector tube outlet, generates a larger flame, thus guaranteeing uniform flame distribution in both the lower and upper channels of the burner.
[0017] In some embodiments, the lower plate is recessed to form a lower channel, and the upper plate is convex to form an upper channel; and the lower channel and the upper channel are directly opposite each other to form the burner's flame hole.
[0018] This ensures that the burner's orifices are aligned, thereby increasing the total area of the burner's orifices and consequently improving the burner's flame intensity and load limit.
[0019] In some embodiments, the depth direction of the fire hole forms an angle θ with the plane where the upper plate is located, and the angle θ ranges from (0° to 90°).
[0020] This causes the burner's flame holes to tilt inward into a conical shape, thereby ensuring the burner's flame concentration effect and improving the burner's flame intensity and heating efficiency.
[0021] In some implementations, the range of the angle θ is (0°, 60°).
[0022] This ensures the burner's flame concentration capability, thereby improving heating efficiency.
[0023] In some implementations, the angle θ is 40°.
[0024] This ensures that the flame generated by the burner is strong enough to provide better heating to the bottom of the cooking appliance.
[0025] In some embodiments, a fire-transfer gap is formed between the upper plate and the partition plate, and the fire-transfer gap connects two adjacent fire holes.
[0026] This connects two adjacent independent flame holes together, ensuring the formation of a complete flame and thus improving the burner's ignition transmission and anti-flameout capabilities.
[0027] In some embodiments, the upper plate is annular and includes an inner ring portion and an outer ring portion. The inner ring portion protrudes upward relative to the outer ring portion and is spaced apart from the partition plate to form the fire transmission gap.
[0028] This allows the flame to be transmitted between the adjacent flame holes on the inner ring of the upper plate and the partition plate. Furthermore, during combustion, air can reach the flame holes through the flame transmission gap, effectively replenishing the secondary air required for combustion and thus improving the burner's combustion efficiency.
[0029] In some embodiments, the arc of the fire-transfer gap distributed at the inner edge of the inner ring of the upper plate is [0°, 360°].
[0030] This creates an annular channel in the flame transfer gap, ensuring that the burner produces an overall annular flame, thereby improving flame stability.
[0031] This invention provides a burner assembly including at least one burner as described in any of the above embodiments. The burner assembly includes an oil cup disposed below the burner. The burner assembly also includes a deflector plate disposed near the burner, the deflector plate being configured to guide oil droplets falling into the burner assembly and sliding down into the oil cup during cooking.
[0032] This ensures that the burner components remain clean and tidy during cooking, reducing cleaning steps and improving the user experience.
[0033] In some embodiments, the burner assembly further includes a support, on which the at least one burner and the oil cup are fixed.
[0034] This improves the stability of the burner assembly, and the bracket is low-cost, simple, and convenient to produce.
[0035] In some embodiments, the partition plate is formed with protrusions that are configured to contact the electric arc generated by the ignition needle.
[0036] In this way, the partition plate forms a protrusion that contacts the electric arc generated by the ignition needle to prevent the arc from running wild, thereby improving the ignition success rate and enhancing the user experience.
[0037] The present invention provides a stove, which includes the burner and burner assembly described in the above embodiments.
[0038] The stove in this embodiment uses a partition plate to separate the lower and upper channels, effectively dividing them into two independent sub-burner holes. The cross-sectional area of each sub-burner hole is reduced, thus increasing its depth. This prevents the flame from entering the gas passage through the sub-burner hole and causing flameout noise at the moment the gas valve is closed. Furthermore, the equivalent cross-sectional area formed by the lower and upper channels remains unchanged, ensuring a larger flame in the burner.

[0060] Please see Figures 1 to 8An embodiment of the present invention provides a burner 100 including a lower plate 10, an upper plate 20 disposed on the lower plate 10, and a partition plate 30. The lower plate 10 has a lower channel 11, and the upper plate 20 has an upper channel 21. The partition plate 30 is disposed between the lower plate 10 and the upper plate 20, and separates the lower channel 11 from the upper channel 21.
[0061] The burner 100 of this embodiment uses a partition plate 30 to separate the lower channel 11 and the upper channel 21, effectively dividing the lower channel 11 and the upper channel 21 into two independent sub-flame holes 41. The cross-sectional area of each sub-flame hole 41 is reduced, and therefore, the depth of the sub-flame hole 41 is relatively increased. This avoids the phenomenon of flame entering the gas passage through the sub-flame hole 41 for combustion and causing flameout noise at the moment the gas valve is closed. In addition, the equivalent cross-sectional area formed by the lower channel 11 and the upper channel 21 remains unchanged, which ensures that the burner 100 has a larger flame.
[0062] Please combine Figure 8 This invention also provides a stove 1000, which includes the burner 100 described in the above embodiments. For example, the stove 1000 can be a natural gas stove, a liquefied petroleum gas stove, or a coal gas stove. The stove 1000 includes a burner assembly 200, which includes at least one burner 100. The stove 1000 can be a single-burner stove, a double-burner stove, or a multi-burner stove. Figure 8 As shown, Figure 8 This is a schematic diagram of a dual-burner stove, where the burner assembly 200 includes at least one burner 100. The burner 100 can be an outer ring burner, an inner ring burner, or a dual-ring burner formed by combining an outer ring burner and an inner ring burner; no specific limitations are imposed here.
[0063] A partition plate 30 is positioned between the lower plate 10 and the upper plate 20 to divide the multiple lower channels 11 and multiple upper channels 21 into two sub-flame holes 41, making the sub-flame holes 41 located on the upper and lower sides of the partition plate 30 independent of each other. That is, the cross-sectional area of the sub-flame holes 41 is relatively reduced, and the depth of the sub-flame holes 41 is relatively increased. At the moment the gas valve closes, the path of the flame returning to the gas passage becomes relatively longer. When the flame reaches the gas passage, the flame is insufficient to reach the extreme conditions for deflagration, thus effectively solving the problem of flameout noise in the burner 100.
[0064] The partition plate 30 is disposed between the lower channel 11 and the upper channel 21, therefore the partition plate 30 can be made of a high-temperature and corrosion-resistant material. In one embodiment, the partition plate 30 can be made of stainless steel. In other embodiments, the partition plate 30 can be made of aluminum alloy, copper alloy, or other materials, without specific limitations.
[0065] Please see Figure 1 In some embodiments, the lower plate 10 and the upper plate 20 are integrally formed of stainless steel.
[0066] Thus, the lower plate 10 and the upper plate 20 are integrally formed from stainless steel, making the inner wall of the burner 100 relatively smooth, thereby reducing airflow resistance and effectively ensuring the supply of air required for complete combustion of gas. In addition, the burner 100 has a simple structure and low cost.
[0067] Specifically, in one embodiment, the lower plate 10 can be used to form the lower channel 11, therefore the lower plate 10 can be made of a high-temperature and corrosion-resistant material. That is, the lower plate 10 can be integrally formed from stainless steel to shorten production time and save production costs. In other embodiments, the lower plate 10 can be integrally formed from aluminum alloy, or from other metal or alloy materials, without specific limitations.
[0068] Similarly, the upper plate 20 can be used to form the upper channel 21, therefore the upper plate 20 can be made of a high-temperature and corrosion-resistant material. That is, the upper plate 20 can be integrally formed from stainless steel to shorten production time and save production costs. In other embodiments, the upper plate 20 can be integrally formed from aluminum alloy, or from other metal or alloy materials, without specific limitations.
[0069] In one embodiment, the lower plate 10 and the upper plate 20 can be connected by welding to form the burner 100. In another embodiment, the lower plate 10 and the upper plate 20 can also be connected by screwing to form the burner 100. In other embodiments, the lower plate 10 and the upper plate 20 can also be connected by other processes to form the burner 100, and no specific limitations are made here.
[0070] In another embodiment, the lower plate 10 and the upper plate 20 can be integrally formed of stainless steel to create the burner 100. This results in a thinner burner 100 with a smooth inner wall, ensuring smooth flow of the gas and air mixture and improving the working efficiency of the burner 100. Furthermore, the integral forming of the lower plate 10 and the upper plate 20 with stainless steel ensures uniform thickness of both plates, guaranteeing uniform heating and improving the uniformity of the flame in the lower channel 11 and the upper channel 21.
[0071] Please see Figure 4 and Figure 6 In some embodiments, the lower plate 10 is recessed to form a lower channel 11, and the upper plate 20 is convex to form an upper channel 21. The lower channel 11 and the upper channel 21 are directly opposite to the flame hole 40 of the burner 100.
[0072] This ensures that the flame holes 40 of the burner 100 are aligned, thereby increasing the total area of the flame holes 40 of the burner, and thus increasing the flame intensity and load limit of the burner 100.
[0073] Specifically, the lower plate 10 can be used to form the fire hole 40, therefore the lower plate 10 can be made of a high-temperature and corrosion-resistant material.
[0074] In one embodiment, the lower plate 10 may be made of aluminum alloy to ensure its bending performance, thereby ensuring the formation of the lower channel 11. In other embodiments, the lower plate 10 may be made of other materials, and no specific limitations are made here.
[0075] Similarly, the upper plate 20 can be used to form a fire hole 40 with the lower plate 10, so the upper plate 20 can be made of a high-temperature and corrosion-resistant material.
[0076] In one embodiment, the upper plate 20 may be made of the same material as the lower plate 10 to ensure the bending performance of the upper plate 20, thereby ensuring the formation of the upper channel 21. In other embodiments, the upper plate 20 may also be made of other materials, and no specific limitations are made here.
[0077] It is understood that the lower channel 11 and the upper channel 21 are formed opposite each other to create a ring-shaped flame hole 40. Compared with a single lower channel 11 or a single upper channel 21 that is staggered, the total area of the flame hole 40 is increased, which increases the amount of gas burned, thereby improving the flame intensity of the burner 100.
[0078] Please see Figure 4 and Figure 6 In some embodiments, the depth direction of the fire hole 40 forms an angle θ with the plane where the upper plate 20 is located, and the range of the angle θ is (0°, 90°).
[0079] This causes the flame holes 40 of the burner 100 to tilt inward into a conical shape, thereby ensuring the flame concentration effect of the burner 100 and improving the flame intensity and heating efficiency of the burner 100.
[0080] Specifically, in one embodiment, the angle θ formed by the depth direction of the burner hole 40 and the plane where the upper plate 20 is located is in the range of (0°, 90°), so that the burner hole 40 of the burner 100 is inclined inward into a conical shape, thereby ensuring the flame concentration effect of the burner 100 and improving the flame intensity of the burner 100 to ensure the heating rate of the bottom of the cooking appliance.
[0081] It is understandable that when the angle formed between the depth direction of the burner hole 40 and the plane where the upper plate 20 is located exceeds the range of (0°, 90°), the flame of the burner 100 spreads outward, resulting in poor flame concentration and easily causing burns and flameout to the user.
[0082] In one implementation, the angle θ ranges from (0° to 90°), i.e., 0° < θ < 90°. In one example, the angle θ can be 5°, 10°, 30°, 45°, 60°, 75°, 85°, or other values between 0° and 90°.
[0083] In some implementations, the angle θ ranges from 0° to 60°.
[0084] This ensures the flame concentration capability of the burner 100, thereby improving heating efficiency.
[0085] Specifically, in one embodiment, preferably, the angle θ formed by the depth direction of the burner hole 40 and the plane where the upper plate 20 is located is in the range of (0°, 60°), so that the burner hole 40 of the burner 100 is inclined inward into a conical shape, thereby ensuring that the flame formed by the burner hole 40 of the burner 100 better covers the bottom of the cooking appliance, thereby improving the heating rate of the burner 100.
[0086] It is understandable that when the angle formed between the depth direction of the fire hole 40 and the plane where the upper plate 20 is located exceeds the range of (0°, 60°), the tilt angle of the flame of the burner 100 increases, which weakens the flame concentration effect and thus reduces the heating rate of the burner 100.
[0087] In one implementation, the angle θ ranges from (0° to 60°), i.e., 0° < θ < 60°. In one example, the angle θ can be 5°, 10°, 15°, 25°, 30°, 45°, 50°, or other values between 0° and 60°.
[0088] In some implementations, the angle θ is 40°.
[0089] This ensures that the flame generated by the burner 100 is strong enough to provide better heating to the bottom of the cooking appliance.
[0090] Specifically, in one embodiment, preferably, the angle θ formed by the depth direction of the burner hole 40 and the plane where the upper plate 20 is located can be 40°. While ensuring that the burner hole 40 of the burner 100 is inclined inward into a conical shape, the flame is concentrated to cover the bottom of the cooking appliance, thereby ensuring a better heating effect at the bottom of the cooking appliance.
[0091] It is understandable that when the θ angle is 40°, the flame generated by the burner 100 can better cover the bottom of the cooking appliance to ensure the heating effect of the bottom of the cooking appliance, thereby improving the gas utilization rate and thus increasing the heating rate of the burner 100.
[0092] Please see Figure 5 and Figure 7 In some embodiments, a fire transmission gap 50 is formed between the upper plate 20 and the partition plate 30, and the fire transmission gap 50 connects two adjacent fire holes 40.
[0093] This connects two adjacent independent flame holes 40 together, ensuring the formation of a complete flame and thus improving the burner's ignition transmission and anti-flameout capabilities.
[0094] Specifically, such as Figure 5 and Figure 7 As shown, in one embodiment, the flame transfer gap 50 can be a channel with a certain spacing d, which can be used to transfer flame.
[0095] Understandable, such as Figure 4 and Figure 6 As shown, the upper plate 20 and the partition plate 30 form a flame transmission gap 50 between two adjacent upper channels 21, so that the two adjacent upper channels 21 can be connected, thereby making the flame of the sub-flame hole 41 of the upper channel 21 stable and uniform.
[0096] That is, the flame can be transferred between the two adjacent sub-flame holes 41 of the two upper channels 21 to improve the flame transfer capability of the two adjacent flame holes 40 of the burner 100.
[0097] In one embodiment, the spacing d of the ignition gap 50 is selected from the range [0.50 mm, 0.80 mm], so that two adjacent independent sub-ignition holes 41 are connected together to ensure the ignition capability of the burner 100.
[0098] The spacing d of the fire-transfer gap 50 is selected from the range of 0.50 mm to 0.80 mm, i.e., 0.50 mm ≤ d ≤ 0.80 mm. In one example, d 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 from 0.50 mm to 0.80 mm.
[0099] Please see Figure 2 and Figure 7 In some embodiments, the upper plate 20 is annular and includes an inner ring portion 221 and an outer ring portion 222. The inner ring portion 221 protrudes upward relative to the outer ring portion 222 and is spaced apart from the partition plate 30 to form a fire transmission gap 50.
[0100] This allows the flame to be transmitted between the adjacent flame holes 40 between the inner ring portion 221 of the upper plate and the partition plate 30. In addition, during combustion, air can reach the flame holes 40 through the flame transmission gap 50, effectively replenishing the secondary air required for combustion, thereby improving the combustion efficiency of the burner 100.
[0101] Specifically, in one embodiment, the inner ring portion 221 of the upper plate protrudes upward relative to the outer ring portion 222 of the upper plate, so that the inner ring portion 221 of the upper plate is spaced apart from the partition plate 30 to form a flame transmission gap 50, ensuring that flames can be transmitted between two adjacent upper channels 21 in the upper plate 20.
[0102] The inner ring 221 of the upper plate protrudes upward relative to the outer ring 222 of the upper plate, so that the outer ring 222 of the upper plate is tightly attached to the partition plate 30 to form a sealed environment and prevent the flame of the upper channel 21 from flowing back from the flame transmission gap 50 along the outer ring 222 of the upper plate, which may cause safety hazards.
[0103] In one embodiment, multiple adjacent sub-fire holes 41 of the upper channel 21 form an integral annular flame, making the formed integral annular flame more stable and less prone to flameout, thereby improving the flameout resistance of the burner 100.
[0104] That is, the flame transfer gap 50 can connect multiple adjacent sub-flame holes 41 of the upper channel 21 at the inner ring 221 of the upper plate together. The flame transfer gap 50 can also connect two adjacent sub-flame holes 41 of the upper channel 21 at the inner ring 221 of the upper plate together to generate an overall annular flame, so as to ensure that a complete flame is formed between the upper plate 20 and the partition plate 30, thereby improving the flame transfer capability and flameout resistance of the burner 100.
[0105] In some embodiments, the arc of the fire-transfer gap 50 distributed at the inner edge of the inner ring portion 221 of the upper plate is [0°, 360°].
[0106] This creates an annular channel in the flame transfer gap 50, ensuring that the burner 100 produces an overall annular flame, thereby improving the stability of the flame.
[0107] Specifically, in one embodiment, the flame transfer gap 50 forms an annular arc channel at the inner edge of the inner ring portion 221 of the upper plate to ensure that the flames of multiple adjacent upper channels 21 are in an overall annular shape, thereby improving the stability of the flames in the upper channels 21 and thus improving the flame stability of the burner 100.
[0108] It is understandable that the flame transfer gap 50 is an annular channel to improve flame stability, thereby improving the flame transfer capability and flameout resistance of the burner 100.
[0109] In one embodiment, the arc of the fire-transfer gap 50 distributed at the inner edge of the inner ring portion 221 of the upper plate is [0°, 360°]. For example, in some cases, the arc of the fire-transfer gap 50 can be 0°, 90°, 180°, 270°, 360° or other angles between 0° and 360°.
[0110] It is worth noting that the larger the curvature of the flame transfer gap 50, for example, if the curvature of the flame transfer gap 50 is 360°, the better the flame stability of the flame hole 40, thereby making the burner 100 have stronger flame transfer capability and anti-flame-out capability.
[0111] In some embodiments, the lower plate 10 and the partition plate 30 are spaced apart to form a fire transmission gap 50 between two adjacent lower channels 11, and / or the upper plate 20 and the partition plate 30 are spaced apart to form a fire transmission gap 50 between two adjacent upper channels 21.
[0112] This connects two adjacent independent lower channels 11 and / or two adjacent independent upper channels 21 together, thereby ensuring the formation of an integral flame and improving the flame transmission capability and flameout resistance of the burner 100.
[0113] Specifically, in one embodiment, the upper plate 20 can be spaced apart from the partition plate 30, allowing communication between adjacent upper channels 21. This means that adjacent sub-flame holes 41 of the two upper channels 21 can transmit flame to each other, thereby improving the flame transmission capability of the burner 100. Furthermore, the multiple adjacent sub-flame holes 41 of the two upper channels 21 form an integral annular flame, making the resulting annular flame more stable and less prone to flameout, thus improving the burner 100's resistance to flameout.
[0114] That is, the ignition gap 50 can connect multiple adjacent sub-ignition holes 41 of the upper channel 21 together, and the ignition gap 50 can also connect two adjacent sub-ignition holes 41 of the upper channel 21 together to generate an overall annular flame, so as to improve the ignition capability and anti-flame-out capability of the burner 100.
[0115] In one embodiment, the lower plate 10 may be spaced apart from the partition plate 30, allowing communication between two adjacent lower channels 11. The effect of the lower plate 10 being spaced apart from the partition plate 30 is the same as the effect of the upper plate 20 being spaced apart from the partition plate 30; to avoid redundancy, this will not be described further.
[0116] The spacing d of the flame transfer gap 50 is selected from the range [0.50mm, 0.80mm], so that two adjacent independent sub-flame holes 41 are connected together to ensure the flame transfer capability and flameout resistance of the burner 100.
[0117] The spacing d of the fire-transfer gap 50 is selected from the range of 0.50 mm to 0.80 mm, i.e., 0.50 mm ≤ d ≤ 0.80 mm. In one example, d 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 from 0.50 mm to 0.80 mm.
[0118] In one embodiment, the lower plate 10 is fitted to the partition plate 30, and the upper plate 20 is spaced apart from the partition plate 30. In this case, adjacent lower channels 11 in the lower plate 10 are not connected, and adjacent sub-flame holes 41 in the lower channels 11 are independently configured and cannot transmit flame to each other. Adjacent upper channels 21 in the upper plate 20 are connected, meaning that adjacent sub-flame holes 41 in the upper channels 21 can transmit flame to each other, thereby improving the flame transmission capability of the burner 100.
[0119] In another embodiment, the upper plate 20 is fitted to the partition plate 30, and the lower plate 10 is spaced apart from the partition plate 30. In this case, two adjacent upper channels 21 in the upper plate 20 are not connected, and two adjacent sub-flame holes 41 in the upper channel 21 are independently arranged and cannot transmit flame to each other. Two adjacent lower channels 11 in the lower plate 10 are connected, that is, two adjacent sub-flame holes 41 in the lower channel 11 can transmit flame to each other, thereby improving the flame transmission capability of the burner 100.
[0120] In other embodiments, the lower plate 10 and the partition plate 30 are spaced apart, and the upper plate 20 and the partition plate 30 are also spaced apart. The spaced arrangement of the lower plate 10 and the partition plate 30 allows communication between adjacent lower channels 11, meaning that adjacent sub-flame holes 41 of the lower channel 11 can transfer flames to each other, thereby improving the flame transfer capability of the burner 100. Furthermore, the multiple adjacent sub-flame holes 41 of the lower channel 11 form an integral annular flame, making the formed integral annular flame more stable and less prone to flameout, thus improving the burner 100's resistance to flameout. Similarly, the spaced arrangement of the upper plate 20 and the partition plate 30 allows communication between adjacent upper channels 21, meaning that adjacent sub-flame holes 41 of the two upper channels 21 can transfer flames to each other, thereby improving the flame transfer capability of the burner 100. Additionally, the multiple adjacent sub-flame holes 41 of the two upper channels 21 form an integral annular flame, making the formed integral annular flame more stable and less prone to flameout, thus improving the burner 100's resistance to flameout.
[0121] It is worth noting that the partition plate 30 separates the flame hole 40 into a lower channel 11 and an upper channel 21, but the multiple lower channels 11 and the multiple upper channels 21 together form an integral annular flame, which is uniform and complete, and there is no phenomenon of flame separation.
[0122] Please see Figure 2 and Figure 3In some embodiments, the lower plate 10 includes a lower plate body 12, and the upper plate 20 includes an upper plate body 22. The lower plate body 12 and the upper plate body 22 are substantially annular. Multiple lower channels 11 are distributed along the inner circumference of the lower plate body 12, and multiple upper channels 21 are distributed along the inner circumference of the upper plate body 22. The lower plate 10 includes a lower ejector tube portion 13 connected to the lower plate body 12, and the lower ejector tube portion 13 forms a lower ejector conduit 131. The lower plate body 12 forms a lower air passage 71 connecting the lower ejector conduit 131 and the lower channels 11. The upper plate 20 includes an upper plate body 22. The upper ejector tube 23 is connected to the plate body 22. The upper ejector tube 23 forms an upper ejector pipe 231. The upper plate body 22 forms an upper air passage 72 that connects the upper ejector pipe 231 and the upper passage 21. The lower ejector tube 13 cooperates with the upper ejector tube 23 to form the ejector tube 60 of the burner 100. The lower air passage 71 and the upper air passage 72 cooperate to form the air passage 70 of the burner 100. The ejector tube 60 and the air passage 70 are connected to form the ejector tube outlet 61. The diameter of the flame hole 40 away from the ejector tube outlet 61 is larger than the diameter of the flame hole 40 near the ejector tube outlet 61.
[0123] In this way, the flame of the burner hole 40 generated by the cooperation of the lower channel 11 and the upper channel 21 is concentrated, while the flame's coverage of the pot bottom is enhanced, thus improving combustion efficiency. In addition, the diameter of the lower channel 11 and the upper channel 21 gradually decreases from the position far from the ejector tube outlet 61 to the position near the ejector tube outlet 61, ensuring that the flame formed by the gas flowing through the burner hole 40 far from the ejector tube outlet is also larger, thereby ensuring the uniformity of the flame of the burner hole 40 of the burner 100.
[0124] Specifically, in one embodiment, a plurality of lower channels 11 are distributed along the inner circumference of the lower plate body 12 and arranged in a ring on the lower plate 10, so that the flames of the sub-fire holes 41 of the plurality of lower channels 11 are dense and vigorous.
[0125] Multiple upper channels 21 are distributed along the inner circumference of the upper plate body 22 and arranged in a ring shape below the upper plate 20, so that the flames of the sub-fire holes 41 of the multiple upper channels 21 are dense and vigorous.
[0126] In other words, the multiple lower channels 11 and multiple upper channels 21 cooperate to form multiple flame holes 40, ensuring that the multiple flame holes 40 are distributed in a ring shape, so that the flame of the flame holes 40 is concentrated and the combustion efficiency is improved. In addition, the ring distribution of multiple flame holes 40 strengthens the flame's coverage of the pot bottom, improves the convective heat transfer coefficient between the flame and the pot bottom, and thus saves gas consumption.
[0127] In one embodiment, the ejector tube 60 is connected to the air passage 70, and the ejector tube 60 is used to mix the gas mixture of fuel gas and air evenly and deliver it to the air passage 70.
[0128] The gas passage 70 is connected to the flame port 40. The gas passage 70 can remix the gas mixture of gas and air to produce a uniform flame through the flame port 40.
[0129] like Figure 2 As shown, in one embodiment, the aperture of the flame hole 40 near the ejector tube outlet 61 is smaller, and the aperture of the flame hole 40 far from the ejector tube outlet 61 is larger. The aperture of the flame hole 40 gradually increases from the position near the ejector tube outlet 61 to the position far from the ejector tube outlet 61, and the aperture of the flame hole 40 reaches its maximum at point M.
[0130] That is, the diameter of the burner hole 40 gradually increases from the position near the ejector tube outlet 61 to the position far away from the ejector tube outlet 61, so as to ensure that the flame generated by the gas flowing through the burner hole 40 at point M is also larger, thereby ensuring that the flame length generated by multiple burner holes 40 is equal, and thus ensuring that the flame of the burner hole 40 of the burner 100 is uniform.
[0131] Please see Figure 2 In some embodiments, the centerline L of the ejector tube 60 is substantially tangent to the center circle R of the airway 70.
[0132] In this way, the gas can flow rapidly along the annular gas passage 70 after entering the gas passage 70 from the ejector tube 60, so as to continuously supply gas to the flame hole 40, increase the gas supply speed of the flame hole 40, and thus ensure that the flame of the flame hole 40 is continuous and uniform.
[0133] Specifically, in one implementation, such as Figure 2 As shown, the gas passage 70 is arranged in a circular shape. When the centerline L of the injector 60 is basically tangent to the center circle R of the gas passage 70, the point of tangency between the centerline L and the center circle R is N. This allows the gas to quickly enter the gas passage 70 from the injector 60, thereby reducing the resistance of the gas passage 70's inner wall to the gas. In addition, after entering the gas passage 70 from the injector 60, the gas can flow rapidly along the circular gas passage 70, thereby ensuring the gas supply speed of the burner hole 40, and thus ensuring that the flame of the burner hole 40 is continuous and uniform.
[0134] Please see Figure 2 and Figure 3 In some embodiments, the cross-sectional area of the airway 70 farther from the ejector outlet 61 is smaller than that of the airway 70 closer to the ejector outlet 61.
[0135] Thus, the cross-sectional area of the gas passage 70 gradually increases from the position far from the ejector tube outlet 61 to the position near the ejector tube outlet 61. That is, the cross-sectional area of the gas passage 70 near the ejector tube outlet 61 is large, which makes the gas mixing more uniform, the gas flow rate is relatively low, and the diameter of the flame hole 40 is small. The cross-sectional area of the gas passage 70 far from the ejector tube outlet 61 is small, the gas flow rate is relatively high, and the diameter of the flame hole 40 is large, thereby improving the uniformity of the flame of the flame hole 40.
[0136] Specifically, in one embodiment, the cross-sectional area of the airway 70 near the ejector outlet 61 is larger, and the cross-sectional area of the airway 70 far from the ejector outlet 61 is smaller. Furthermore, the cross-sectional area of the airway 70 gradually decreases from the position near the ejector outlet 61 to the position far from the ejector outlet 61, and the cross-sectional area of the airway 70 is the smallest at point M.
[0137] With a constant gas flow rate, the cross-sectional area of the gas passage 70 is larger near the ejector outlet 61, while the gas velocity is relatively smaller, facilitating uniform mixing of gas and air. Conversely, the cross-sectional area M of the gas passage 70 is smaller further away from the ejector outlet 61, while the gas velocity M is relatively larger, facilitating rapid delivery of the uniformly mixed gas and air to the burner hole 40.
[0138] It is worth noting that the cross-sectional area M of the air passage 70 gradually decreases from the position near the ejector tube outlet 61 to the position far away from the ejector tube outlet 61, and the aperture size M of the flame hole 40 gradually increases from the position near the ejector tube outlet 61 to the position far away from the ejector tube outlet 61. This makes the cross-sectional area of the air passage 70 and the aperture size of the flame hole 40 match each other to improve the uniformity of the flame of the flame hole 40.
[0139] Please see Figure 9 In some embodiments, the partition plate 30 includes a partition plate body 31 located between the lower plate 10 and the upper plate 20. The partition plate body 31 is basically annular. The partition plate 30 also includes a flange 32 that is bent from the outer peripheral edge of the partition plate body 31 toward the lower plate 10. The flange 32 is basically arc-shaped and is provided corresponding to the ejector outlet 61 to block the gas from entering the flame hole 40 corresponding to the flange 32 through the gas passage 70 from the ejector outlet 61.
[0140] Thus, with all the flame holes 40 having the same size, the cross-sectional area of the gas passage 70 gradually increases from the position far from the ejector tube outlet 61 to the position close to the ejector tube outlet 61. The flange 32 is basically arc-shaped and is set corresponding to the ejector tube outlet 61 to block the gas from entering the flame hole 40 corresponding to the flange 32 through the gas passage 70 from the ejector tube outlet 61, thereby reducing the gas output of the flame hole 40 corresponding to the flange 32, and thus reducing the flame length of the flame hole 40 corresponding to the flange 32, so as to ensure the uniformity of the flame of the flame hole 40.
[0141] Specifically, in one embodiment, when the aperture size of the flame holes 40 is the same, the cross-sectional area M of the gas passage 70 gradually decreases from the position near the ejector tube outlet 61 to the position far away from the ejector tube outlet 61. The uniformity of the flame of all flame holes 40 can be ensured by the flange 32 provided on the partition plate 30.
[0142] In one embodiment, the flange 32 can be bent toward the lower plate 10 to block the flow of gas in different flame holes 40, so as to ensure that the flame length of all flame holes 40 is the same, thereby ensuring the uniformity of the flame of the flame holes 40.
[0143] In another embodiment, the flange 32 can also be bent toward the upper plate 20 to block the flow of gas in different flame holes 40, so as to ensure that the flame length of all flame holes 40 is the same, thereby ensuring the uniformity of the flame of the flame holes 40.
[0144] In other embodiments, the flange 32 can be bent in both the direction of the lower plate 10 and the direction of the upper plate 20 to ensure that the flame length of all the flame holes 40 is the same, thereby ensuring the uniformity of the flame of the flame holes 40.
[0145] Please see Figure 10 In some embodiments, the arc angle of the flange 32 is from 0 degrees to 180 degrees.
[0146] Thus, by setting a flange 32 with a certain arc angle on the partition plate 30 to adjust the flame length of the fire hole 40, the uniformity of the flame of the fire hole 40 is ensured.
[0147] Specifically, the flange 32 is located on the partition plate 30 and connected to the partition plate body 31. It can be used to block the gas from entering the corresponding burner hole 40 of the flange 32 through the gas passage 70 from the injector outlet 61. That is, the flange 32 can be made of a high-temperature and corrosion-resistant material. In one embodiment, the flange 32 can be made of stainless steel. In other embodiments, the flange 32 can be made of aluminum alloy, copper alloy, or other materials, without specific limitations.
[0148] Preferably, in one embodiment, such as Figure 10 As shown, the arc angle of the flange 32 on the partition plate 30 is A. The arc angle A is selected from the range of 0 degrees to 180 degrees to block the gas from entering the corresponding burner hole 40 of the flange 32 through the gas passage 70 from the injector outlet 61, thereby reducing the gas output of the corresponding burner hole 40 of the flange 32 and thus reducing the flame length of the corresponding burner hole 40 of the flange 32, so as to ensure the uniformity of the flame of the burner hole 40.
[0149] The arc angle A is selected from the range of 0 degrees to 180 degrees, i.e., 0°≤A≤180°. In one example, the arc angle A can be 0°, 45°, 90°, 120°, 135°, 150°, 180° or other values from 0° to 180°.
[0150] In some implementations, the arc angle of the flange is from 0 to 150 degrees.
[0151] This allows for more precise adjustment of the flame length of the fire hole 40, thereby ensuring the uniformity of the flame in the fire hole 40.
[0152] Specifically, in one implementation, such as Figure 10 As shown, the arc angle of the flange 32 on the partition plate 30 is B.
[0153] It is understandable that the arc angle B is selected from the range of 0 degrees to 150 degrees, so as to block the gas from entering the flame hole 40 corresponding to the flange 32 through the gas passage 70 from the ejector tube outlet 61, reduce the gas output of the flame hole 40 corresponding to the flange 32, and thus reduce the flame length of the flame hole 40 corresponding to the flange 32, so as to ensure the uniformity of the flame of the flame hole 40.
[0154] In one implementation, the arc angle B is selected from the range of 0 degrees to 150 degrees, i.e., 0° ≤ B ≤ 150°. In one example, the arc angle B can be 0°, 45°, 90°, 100°, 120°, 135°, 150° or other values from 0° to 150°.
[0155] In another embodiment, the arc angle B of the flange 32 on the partition plate 30 can also be set to 360 degrees. For example, the supply of gas in the flame hole 40 can be changed by changing the length or tilt angle of the flange 32 in different positions of the partition plate 30, so as to ensure that the supply of gas in the flame hole 40 is the same, thereby ensuring the uniformity of the flame in the flame hole 40.
[0156] In other embodiments, the arc angle A of the flange 32 can also be set to any arc angle between 0 degrees and 360 degrees, as long as the gas supply in the flame hole 40 is the same, thereby ensuring the uniformity of the flame in the flame hole 40. No specific restrictions are imposed here.
[0157] Please see Figure 2 and Figure 3 In some embodiments, the depth direction of the lower channel 11 is inclined relative to the radial direction of the lower plate body 12 and / or the depth direction of the upper channel 21 is inclined relative to the upper plate body 22.
[0158] Radial tilt.
[0159] In this way, the flame of the fire hole 40 formed by the cooperation of the lower channel 11 and the upper channel 21 is concentrated, making the flame more vigorous and improving the combustion efficiency of the gas.
[0160] Specifically, such as Figure 3 As shown, the angle between the depth direction of the lower channel 11 and the radial direction of the lower plate body 12 is E. The depth direction of one of the lower channels 11 is the solid line direction of angle E, and the radial direction of one of the lower plate bodies 12 is the dashed line direction of angle E.
[0161] The depth direction of the lower channel 11 is inclined relative to the radial direction of the lower plate body 12, which causes the flame of the sub-flame hole 41 of the lower channel 11 to converge towards the inner circumference of the lower plate body 12, making the flame more vigorous and improving the combustion efficiency of the gas.
[0162] like Figure 2 As shown, the angle between the depth direction of the upper channel 21 and the radial direction of the upper plate body 22 is F. The depth direction of one of the upper channels 21 is the solid line direction of angle F, and the radial direction of one of the upper plate bodies 22 is the dashed line direction of angle F.
[0163] The depth direction of the upper channel 21 is inclined relative to the radial direction of the upper plate body 22, which causes the flame of the sub-flame hole 41 of the upper channel 21 to converge towards the inner circumference of the upper plate body 22, making the flame more vigorous and improving the combustion efficiency of the gas.
[0164] In summary, the flame concentration in the fire hole 40 formed by the cooperation of the lower channel 11 and the upper channel 21 results in a more vigorous flame, thereby improving the combustion efficiency of the gas.
[0165] In some embodiments, the lower plate body 12 includes a lower plate inner ring portion 121, a lower channel 11 is formed in the lower plate inner ring portion 121, and the lower plate inner ring portion 121 arches radially from the outside to the inside toward the upper plate 20. The upper plate body 22 includes an upper plate inner ring portion 221, an upper channel 21 is formed in the upper plate inner ring portion 221, and the upper plate inner ring portion 221 arches radially from the outside to the inside toward the direction away from the lower plate 10.
[0166] Thus, the inner ring portion 121 of the lower plate and the inner ring portion 221 of the upper plate are arranged in the same direction to ensure that they cooperate to form multiple fire holes 40 that face upwards and have the same orientation as the lower channel 11 and the upper channel 21, so that the flame of the fire hole 40 is closer to the bottom of the pot and the heat transfer efficiency between the flame and the bottom of the pot is improved.
[0167] Specifically, such as Figure 1 and Figure 3 As shown, in one embodiment, the lower plate inner ring 121 is arranged in a circular shape, and the lower plate inner ring 121 arches radially from the outside to the inside toward the upper plate 20 to support the upper plate inner ring 221, thereby improving the stability of the upper plate inner ring 221.
[0168] like Figure 1 and Figure 2 As shown, the inner ring 221 of the upper plate is arranged in a circular shape, and the inner ring 221 of the upper plate arches radially from the outside to the inside away from the lower plate 10, so as to cooperate with the inner ring 121 of the lower plate to form a plurality of fire holes 40 distributed in a circular shape, so that the fire holes 40 are closer to the bottom of the pot, thereby improving the heat transfer efficiency between the flame and the bottom of the pot.
[0169] Please see Figures 11 to 13 The present invention also provides a burner assembly 200. The burner assembly 200 includes at least one burner 100 as described in any of the above embodiments. The burner assembly 200 includes an oil cup 210 disposed below the burner 100. The burner assembly 200 also includes a deflector 220 disposed near the burner 100. The deflector 220 is configured to guide oil droplets falling into the burner assembly 200 during cooking to slide down into the oil cup 210.
[0170] This ensures that the burner assembly 200 remains clean and tidy during cooking, reducing cleaning steps and improving the user experience.
[0171] Specifically, in one embodiment, the baffle 220 is arranged in a funnel shape between multiple burners 100 (e.g., an inner ring burner and an outer ring burner) and can be used to guide oil droplets generated during the cooking process into the oil cup 210 along the inner wall to improve the cleanliness of the burner assembly 200.
[0172] In addition, the baffle 220 is arranged in a funnel shape between multiple burners 100 (e.g., inner ring burners and outer ring burners), which can increase the space between multiple burners 100, ensure the supply of secondary air, and improve the combustion efficiency of the burner assembly 200.
[0173] The baffle 220 is arranged in a funnel shape between multiple burners 100 and can also be used to cover the internal structure of the burner assembly 200, making the burner assembly 200 look beautiful and simple.
[0174] In one embodiment, the oil cup 210 can be used to collect oil droplets that flow down the deflector 220 during cooking, improving kitchen cleanliness and thus enhancing the user experience.
[0175] Please see Figure 13 and Figure 14 In some embodiments, the burner assembly 200 further includes a bracket 230, on which at least one burner 100 and oil cup 210 are fixed.
[0176] This improves the stability of the burner assembly 200, and the bracket 230 is low-cost, simple, and convenient to produce.
[0177] Specifically, in one embodiment, the bracket 230 may be disposed at the bottom of the burner assembly 200, and the bracket 230 forms a cylindrical inner cavity that can be used to hold the oil cup 210, ensuring that the burner assembly 200 is clean and hygienic.
[0178] In one embodiment, the bracket 230 includes multiple claws for securing at least one burner 100 and oil cup 210, ensuring stable operation of the burner assembly 200 and improving safety during kitchen cooking.
[0179] In one embodiment, the bracket 230 can be integrally formed from aluminum alloy to reduce weight and lower production costs. Additionally, the bracket 230 can be used to secure multiple components, improving the installation efficiency of the burner assembly 200.
[0180] In one embodiment, the bracket 230 can be formed by die casting or other processes, without any specific limitation.
[0181] In one embodiment, the burner assembly 200 further includes a retaining plate 240 and an ignition needle 250.
[0182] The fixing plate 240 can be fixed to the bracket 230 with screws to reinforce the burner 100 and further improve the stability of the burner 100.
[0183] The ignition needle 250 can be installed in conjunction with the guide plate 220 to be fixed on the bracket 230, thereby generating an electric arc to ignite the gas at the flame hole 40 of the burner 100, and thus producing a uniform flame.
[0184] Please see Figure 11 and Figure 12 In some embodiments, the partition plate 30 is formed with a protrusion 33, which is configured to contact the electric arc generated by the ignition needle 250.
[0185] In this way, the partition plate 30 forms a protrusion 33, which contacts the electric arc generated by the ignition needle 250 to prevent the electric arc from running wild, thereby improving the ignition success rate and enhancing the user experience.
[0186] Specifically, the protrusion 33 is disposed on the partition plate 30 and can be used to attract the electric arc generated by the ignition needle 250, so that the electric arc ignites the gas at the protrusion 33 to form a flame, so as to prevent the discharge arc of the ignition needle 250 from deviating from the direction of the partition plate 30, thereby improving the ignition success rate of the burner 100.
[0187] It is understood that the upper plate 20 and the partition plate 30 form a flame transmission gap 50 between two adjacent upper channels 21. When the electric arc generated by the ignition needle 250 contacts the protrusion 33, the efficiency of the flame hole 40 in forming an overall annular flame can be improved, thereby increasing the ignition success rate of the burner 100.
