Combustor, combustor assembly and stove

Abstract

The invention discloses a combustor, a combustor assembly and a stove. The combustor comprises a lower plate, an upper plate arranged on the lower plate and a partition plate. A lower hole channel is formed in the lower plate, and an upper hole channel is formed in the upper plate. The partition plate is arranged between the lower plate and the upper plate and separates the lower hole channel from the upper hole channel. According to the combustor, the partition plate is adopted to divide the lower hole channel and the upper hole channel into the two independent fire sub-holes, the cross section area of each fire sub-hole is decreased, and therefore the depth of each fire sub-hole is increased relatively. In this way, flame can be prevented from entering the gas channel for combustion through the sub-fire holes at the moment when the gas valve is closed to generate flameout noise and the like. In addition, the equivalent cross section area formed by the lower hole channel and the upper hole channel is not changed, and it can be guaranteed that the combustor has large flame.

Description

Technical Field

[0001] The invention relates to the technical field of kitchen appliances, and in particular to a burner, a burner assembly and a cooker. Background Art

[0002] In order to obtain a larger flame, the fire hole of the burner is generally set larger, so the cross-sectional area of ​​the fire hole is larger. Relatively speaking, the depth of the fire hole is insufficient. Therefore, the flame can easily enter the gas passage through the fire hole and burn at the moment the gas valve is closed, causing flameout noise and other phenomena. Summary of the invention

[0003] Embodiments of the present invention provide a burner, a burner assembly and a cooker.

[0004] An embodiment of the present invention provides a burner, comprising:

[0005] Lower plate;

[0006] An upper plate disposed on the lower plate, the lower plate being formed with a lower hole channel, and the upper plate being formed with an upper hole channel; and

[0007] A partition plate is disposed between the lower plate and the upper plate and separates the lower hole channel from the upper hole channel.

[0008] The burner of the embodiment of the present application uses a partition plate to separate the lower channel and the upper channel, which is equivalent to dividing the lower channel and the upper channel into two independent sub-fire holes. The cross-sectional area of ​​each sub-fire hole becomes smaller, so relatively speaking, the depth of the sub-fire hole becomes deeper. This can avoid the flame entering the gas channel through the sub-fire hole at the moment when the gas valve is closed, causing flameout noise and other phenomena. In addition, the equivalent cross-sectional area formed by the lower channel and the upper channel does not change, which can ensure that the burner has a larger flame.

[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 is substantially annular, and the partition plate also includes a flange bent from the outer peripheral edge of the partition plate body toward the lower plate.

[0010] In this way, the flange is bent toward the lower plate to block the gas from entering the lower and upper channels corresponding to the flange from the gas channel, reducing the gas output of the lower and upper channels corresponding to the flange, and then reducing the flame length of the lower and upper channels corresponding to the flange to ensure the uniformity of the flame of the lower and upper channels.

[0011] In some embodiments, the arc angle of the flange is 0 to 180 degrees.

[0012] In this way, the flame lengths of the lower and upper channels are adjusted by setting flanges with a certain arc angle on the partition plate, thereby ensuring the uniformity of the flames of the lower and upper channels.

[0013] In some embodiments, the arc angle of the flange is 0 to 150 degrees.

[0014] In this way, the flame lengths of the lower and upper channels can be further accurately adjusted, thereby ensuring the uniformity of the flames of the lower and upper channels.

[0015] In some embodiments, the lower plate includes a lower plate body, the upper plate includes an upper plate body, the lower plate body and the upper plate body are basically annular, the lower channels are multiple and distributed along the inner circumference of the lower plate body, the upper channels are multiple and distributed along the inner circumference of the upper plate body, the lower plate includes a lower ejection pipe portion connected to the lower plate body, the lower ejection pipe portion is formed with a lower ejection pipeline, the lower plate body is formed with a lower airway connecting the lower ejection pipeline and the lower channel, and the upper plate includes a lower ejection pipe connected to the upper plate body The upper ejector pipe part is connected, the upper ejector pipe part is formed with an upper ejector pipeline, the upper plate body is formed with an upper air duct connecting the upper ejector pipeline and the upper channel, the lower ejector pipe part cooperates with the upper ejector pipe part to form the ejector pipe of the burner, the lower air duct and the upper air duct cooperate to form the air duct of the burner, the ejector pipe is connected with the air duct to form an ejector pipe outlet, the aperture of the upper channel and the lower channel away from the ejector pipe outlet is larger than the aperture of the upper channel and the lower channel close to the ejector pipe outlet.

[0016] In this way, the flame generated by the cooperation between the lower channel and the upper channel is cohesive, and the flame wrapping the bottom of the pot is strengthened, thereby improving the combustion efficiency. In addition, the aperture size of the lower channel and the upper channel gradually decreases from the position far from the outlet of the ejector tube to the position close to the outlet of the ejector tube, ensuring that the flame formed by the gas flowing through the lower channel and the upper channel far from the outlet of the ejector tube is also larger, thereby ensuring that the flame of the lower channel and the upper channel of the burner is uniform.

[0017] In some embodiments, the lower plate is concave to form a lower channel, and the upper plate is convex to form an upper channel; and the lower channel and the upper channel face each other to form a fire hole of the burner.

[0018] In this way, the fire holes of the burner are formed in a right-angled manner, thereby increasing the total area of ​​the fire holes of the burner, and further increasing the flame intensity and load upper limit of the burner.

[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 range of the angle θ is (0°, 90°).

[0020] In this way, the fire hole of the burner is inclined inwardly into a cone shape, thereby ensuring the flame gathering effect of the burner, thereby improving the flame intensity and heating efficiency of the burner.

[0021] In certain embodiments, the angle θ is in the range of (0°, 60°).

[0022] In this way, the flame focusing ability of the burner is ensured, thereby improving the heating efficiency.

[0023] In certain embodiments, the angle θ is 40°.

[0024] In this way, it is ensured that the flame intensity formed by the burner is greater, so that the heating effect of the bottom of the cooking utensil is better.

[0025] In certain 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] In this way, two adjacent independent fire holes are connected together, thereby ensuring the formation of an integral flame, thereby improving the flame transfer ability and anti-fire ability of the burner.

[0027] In some embodiments, the upper plate is annular and includes an upper plate inner ring portion and an upper plate outer ring portion, the upper plate inner ring portion protrudes upward relative to the upper plate outer ring portion and is spaced apart from the partition plate to form the fire transfer gap.

[0028] In this way, the adjacent fire holes between the inner ring of the upper plate and the partition plate can transmit flames. In addition, during the combustion process, air can reach the fire holes through the flame transmission gap, effectively supplementing the secondary air required for combustion, thereby improving the combustion efficiency of the burner.

[0029] In certain embodiments, the arc of the fire transfer gap distributed at the inner edge of the inner ring portion of the upper plate is [0°, 360°].

[0030] In this way, the fire transfer gap forms an annular channel, thereby ensuring that the burner produces an overall annular flame, thereby improving the stability of the flame.

[0031] An embodiment of the present invention provides a burner assembly, which includes at least one burner as described in any of the above embodiments, the burner assembly includes an oil cup, the oil cup is arranged below the burner, the burner assembly also includes a guide plate arranged near the burner, the guide plate is configured to guide oil droplets falling into the burner assembly to slide off the oil cup during the cooking process.

[0032] In this way, the burner assembly is kept clean and tidy during the cooking process, the cleaning steps are reduced, and the user experience is improved.

[0033] In certain embodiments, the burner assembly further comprises a bracket, and the at least one burner and the oil cup are fixed on the bracket.

[0034] In this way, the stability of the burner assembly is improved, and the production cost of the bracket is low, simple and convenient.

[0035] In certain embodiments, the separator plate is formed with a protrusion configured to contact an arc generated by an ignition needle.

[0036] In this way, the 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.

[0037] An embodiment of the present invention provides a cooker, which includes the burner and the burner assembly described in the above embodiment.

[0038] The stove of the embodiment of the present application uses a partition plate to separate the lower channel and the upper channel, which is equivalent to dividing the lower channel and the upper channel into two independent sub-fire holes. The cross-sectional area of ​​each sub-fire hole becomes smaller, so relatively speaking, the depth of the sub-fire hole becomes deeper. This can avoid the flame entering the gas channel through the sub-fire hole at the moment when the gas valve is closed to burn and produce flameout noise and other phenomena. In addition, the equivalent cross-sectional area formed by the lower channel and the upper channel does not change, which can ensure that the burner has a larger flame.

[0059] The disclosure herein provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described herein. Of course, they are merely examples, and the purpose is not to limit the present invention.

[0060] See also Figures 1 to 8A burner 100 provided in an embodiment of the present invention includes a lower plate 10, an upper plate 20 disposed on the lower plate 10, and a partition plate 30. The lower plate 10 is formed with a lower channel 11, and the upper plate 20 is formed with 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 the embodiment of the present application uses a partition plate 30 to separate the lower channel 11 and the upper channel 21, which is equivalent to separating the lower channel 11 and the upper channel 21 into two independent sub-fire holes 41, and the cross-sectional area of ​​each sub-fire hole 41 becomes smaller. Therefore, relatively speaking, the depth of the sub-fire hole 41 becomes deeper. In this way, it can be avoided that the flame enters the gas channel through the sub-fire hole 41 at the moment when the gas valve is closed to burn and produce flameout noise and the like. In addition, the equivalent cross-sectional area formed by the lower channel 11 and the upper channel 21 does not change, which can ensure that the burner 100 has a larger flame.

[0062] Please combine Figure 8 The embodiment of the present invention further provides a stove 1000, which includes the burner 100 in the above embodiment. For example, the stove 1000 may be a natural gas stove, a liquefied gas stove or a coal gas stove. The stove 1000 includes a burner assembly 200, and the burner assembly 200 includes at least one burner 100. The stove 1000 may be a single-burner stove, a double-burner stove, or a multi-burner stove. Figure 8 As shown, Figure 8 2 is a schematic diagram of the structure of a double-burner stove, that is, 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 double ring burner formed by combining an outer ring burner and an inner ring burner, which is not specifically limited here.

[0063] The partition plate 30 is disposed between the lower plate 10 and the upper plate 20, and is used to separate the plurality of lower channels 11 and the plurality of upper channels 21 into two sub-fire holes 41, respectively, so that the sub-fire holes 41 located on the upper and lower sides of the partition plate 30 are independent of each other, that is, the cross-sectional area of ​​the sub-fire hole 41 is relatively reduced, and the depth of the sub-fire hole 41 is relatively deepened. At the moment when the gas valve is closed, the path of the flame return gas channel becomes relatively longer. When the flame reaches the gas channel, the flame is not enough to reach the limit condition of deflagration, so the problem of flameout noise of the burner 100 can be effectively solved.

[0064] The partition plate 30 is disposed between the lower channel 11 and the upper channel 21, so the partition plate 30 may be made of a high temperature resistant and corrosion resistant material. In one embodiment, the material of the partition plate 30 may be a stainless steel partition plate. In other embodiments, the material of the partition plate 30 may be an aluminum alloy partition plate, a copper alloy partition plate, or a partition plate of other materials, which is not specifically limited here.

[0065] See also 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 of stainless steel, so that the inner wall of the burner 100 is relatively smooth, thereby reducing air flow resistance and effectively ensuring the supply of air required for complete combustion of the 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, so the lower plate 10 can be made of a high temperature resistant and corrosion resistant material. That is, the lower plate 10 can be integrally formed with a stainless steel material to shorten the production time and save production costs. In other embodiments, the lower plate 10 can be integrally formed with an aluminum alloy material, or can be integrally formed with other metal materials or alloy materials, which are not specifically limited here.

[0068] Similarly, the upper plate 20 can be used to form the upper channel 21, so the upper plate 20 can be made of a high temperature resistant and corrosion resistant material. That is, the upper plate 20 can be integrally formed with a stainless steel material to shorten the production time and save production costs. In other embodiments, the upper plate 20 can be integrally formed with an aluminum alloy material, or can be integrally formed with other metal materials or alloy materials, which are not specifically limited here.

[0069] In one embodiment, the lower plate 10 and the upper plate 20 may be connected by a welding process to form the burner 100. In another embodiment, the lower plate 10 and the upper plate 20 may also be connected by a screwing process to form the burner 100. In other embodiments, the lower plate 10 and the upper plate 20 may also be connected by other processes to form the burner 100, which are not specifically limited herein.

[0070] In another embodiment, the lower plate 10 and the upper plate 20 may be formed into a burner 100 by integrally forming stainless steel, so that the burner 100 is thin and has a smooth inner wall, thereby ensuring that the gas and air mixture can be smoothly transported, thereby improving the working efficiency of the burner 100. In addition, the lower plate 10 and the upper plate 20 may be formed into a burner 100 by integrally forming stainless steel, so that the thickness of the lower plate 10 and the upper plate 20 is uniform, ensuring that the lower plate 10 and the upper plate 20 are heated uniformly, thereby improving the uniformity of the flames of the lower channel 11 and the upper channel 21.

[0071] See also Figure 4 and Figure 6 In some embodiments, the lower plate 10 is concave 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 opposite to form a fire hole 40 of the burner 100.

[0072] In this way, the fire holes 40 of the burner 100 are formed in a right-angled manner, thereby increasing the total area of ​​the fire holes 40 of the burner, and further increasing the flame intensity and load upper limit of the burner 100.

[0073] Specifically, the lower plate 10 can be used to form the fire hole 40, so the lower plate 10 can be made of a high temperature resistant and corrosion resistant material.

[0074] In one embodiment, the lower plate 10 may be made of aluminum alloy material to ensure the bending performance of the lower plate 10, thereby ensuring the forming of the lower channel 11. In other embodiments, the lower plate 10 may also be made of other materials, which are not specifically limited here.

[0075] Similarly, the upper plate 20 can be used to form the fire hole 40 with the lower plate 10, so the upper plate 20 can be made of a high temperature resistant and corrosion resistant material.

[0076] In one embodiment, the upper plate 20 can be made of the same material as the lower plate 10 to ensure the bending performance of the upper plate 20, thereby ensuring the forming of the upper channel 21. In other embodiments, the upper plate 20 can also be made of other materials, which are not specifically limited here.

[0077] It can be understood that the lower channel 11 and the upper channel 21 are formed opposite to each other to form a ring-shaped fire hole 40. Compared with the single lower channel 11 or the single upper channel 21 arranged in a staggered manner, the total area of ​​the fire hole 40 is increased, so that the combustion amount of the gas is increased, thereby improving the flame intensity of the burner 100.

[0078] See also 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] In this way, the fire hole 40 of the burner 100 is inclined inwardly into a cone shape, thereby ensuring the flame gathering effect of the burner 100, thereby 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 fire hole 40 and the plane where the upper plate 20 is located is in the range of (0°, 90°), so that the fire hole 40 of the burner 100 is inclined inward into a cone shape, thereby ensuring the flame gathering effect of the burner 100, and then improving the flame intensity of the burner 100 to ensure the heating rate of the bottom of the cooking utensil.

[0081] It can be understood that when the angle formed by the depth direction of the fire 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 along the periphery, resulting in poor flame gathering effect, which can easily cause burns to users and flameout.

[0082] In one embodiment, the angle θ ranges from (0°, 90°), that is, 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 certain embodiments, the angle θ is in the range of (0°, 60°).

[0084] In this way, the flame focusing ability of the burner 100 is ensured, thereby improving the heating efficiency.

[0085] Specifically, in one embodiment, preferably, the angle θ formed by the depth direction of the fire hole 40 and the plane where the upper plate 20 is located is in the range of (0°, 60°), so that the fire hole 40 of the burner 100 is inclined inwardly into a cone shape, thereby ensuring that the flame formed by the fire hole 40 of the burner 100 better covers the bottom of the cooking utensil, thereby improving the heating rate of the burner 100.

[0086] It can be understood that when the angle formed by 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 inclination angle of the flame of the burner 100 increases, so that the focusing effect of the flame is weakened, thereby reducing the heating rate of the burner 100.

[0087] In one embodiment, the angle θ ranges from (0°, 60°), that is, 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 certain embodiments, the angle θ is 40°.

[0089] In this way, it is ensured that the flame intensity formed by the burner 100 is greater, so that the heating effect of the bottom of the cooking utensil is better.

[0090] Specifically, in one embodiment, preferably, the angle θ formed by the depth direction of the fire hole 40 and the plane where the upper plate 20 is located can be 40°. Under the condition that the fire hole 40 of the burner 100 is tilted inward into a cone shape, the flame is cohesive to cover the bottom of the heating cooking utensil, thereby ensuring a better heating effect on the bottom of the cooking utensil.

[0091] It can be understood that when the angle θ is 40°, the flame formed by the burner 100 can better cover the bottom of the cooking utensil to ensure the heating effect of the bottom of the cooking utensil, thereby improving the gas utilization rate and further improving the heating rate of the burner 100.

[0092] See also Figure 5 and Figure 7 In some embodiments, a fire transfer gap 50 is formed between the upper plate 20 and the partition plate 30 , and the fire transfer gap 50 connects two adjacent fire holes 40 .

[0093] In this way, two adjacent independent fire holes 40 are connected together, thereby ensuring the formation of an integral flame, thereby improving the flame transfer capability and anti-fire-out capability of the burner.

[0094] Specifically, Figure 5 and Figure 7 As shown, in one embodiment, the flame transfer gap 50 may be a channel with a certain distance d, which can be used to transfer flames.

[0095] It is understandable that Figure 4 and Figure 6 As shown, the upper plate 20 and the partition plate 30 form a fire transfer gap 50 between two adjacent upper channels 21, so that the two adjacent upper channels 21 can be connected, thereby making the flames of the sub-fire holes 31 of the upper channels 21 stable and uniform.

[0096] That is, the flames of two adjacent sub-fire holes 31 of the two upper channels 21 can be transferred to each other, so as to improve the flame transfer capability of two adjacent fire holes 40 of the burner 100 .

[0097] In one embodiment, the interval d of the flame transfer gap 50 is selected from the range of [0.50 mm, 0.80 mm], so that two adjacent independent sub-ignition holes 31 are connected together to ensure the flame transfer capability of the burner 100 .

[0098] The spacing d of the spark gap 50 is selected from the range of 0.50 mm to 0.80 mm, that is, 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 ​​of 0.50 mm to 0.80 mm.

[0099] See also Figure 2 and Figure 7 In some embodiments, the upper plate 20 is annular and includes an upper plate inner ring portion 221 and an upper plate outer ring portion 222. The upper plate inner ring portion 221 protrudes upward relative to the upper plate outer ring portion 222 and is spaced apart from the partition plate 30 to form a fire transfer gap 50.

[0100] Thus, the flames can be transmitted between the adjacent fire holes 40 between the upper plate inner ring portion 221 and the partition plate 30. In addition, during the combustion process, air can reach the fire holes 40 through the flame transmission gap 50, effectively supplementing the secondary air required for combustion, thereby improving the combustion efficiency of the burner 100.

[0101] Specifically, in one embodiment, the upper plate inner ring portion 221 protrudes upward relative to the upper plate outer ring portion 222, so that the upper plate inner ring portion 221 is spaced apart from the partition plate 30 to form a fire transfer gap 50, ensuring that flames can be transferred between two adjacent upper channels 21 in the upper plate 20.

[0102] The upper plate inner ring portion 221 protrudes upward relative to the upper plate outer ring portion 222, so that the upper plate outer ring portion 222 is closely arranged with the partition plate 30 to form a closed environment, thereby preventing the flame of the upper channel 21 from flowing back from the fire transfer gap 50 along the upper plate outer ring portion 222 to cause safety hazards.

[0103] In one embodiment, a plurality of adjacent sub-fire holes 31 of the upper channel 21 form an overall annular flame, so that the formed overall annular flame is relatively stable and not prone to flameout, thereby improving the flameout resistance of the burner 100 .

[0104] That is, the fire transfer gap 50 can connect together a plurality of adjacent sub-fire holes 31 of the upper channel 21 at the inner ring portion 221 of the upper plate, and the fire transfer gap 50 can also connect together two adjacent sub-fire holes 31 of the upper channel 21 at the inner ring portion 221 of the upper plate, 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 fire transfer ability and anti-fire ability of the burner 100.

[0105] In some embodiments, the arc of the fire transfer gap 50 distributed at the inner edge of the upper plate inner ring portion 221 is [0°, 360°].

[0106] In this way, the flame transfer gap 50 forms an annular channel, thereby ensuring that the burner 100 generates an overall annular flame, thereby improving the stability of the flame.

[0107] Specifically, in one embodiment, the fire transfer gap 50 forms a channel with an annular arc at the inner edge of the inner ring portion 22 to ensure that the flames of multiple adjacent upper channels 21 are in an overall annular shape, thereby improving the stability of the flames of the upper channels 21 and further improving the flame stability of the burner 100.

[0108] It can be understood 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 upper plate inner ring portion 221 is [0°, 360°]. For example, in some examples, 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 arc of the fire transfer gap 50 , for example, the arc of the fire transfer gap 50 is 360°, the better the flame stability of the fire hole 40 , thereby making the burner 100 have stronger fire transfer ability and anti-fire ability.

[0111] In some embodiments, the lower plate 10 and the partition plate 30 are spaced apart to form a fire transfer 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 transfer gap 50 between two adjacent upper channels 21 .

[0112] In this way, two adjacent independent lower channels 11 and / or two adjacent independent upper channels 21 are connected together, thereby ensuring the formation of an integral flame, thereby improving the flame transfer 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 so that two adjacent upper channels 21 can be connected, that is, two adjacent sub-fire holes 41 of the two upper channels 21 can transfer flames to each other, so as to improve the flame transfer capability of the burner 100. In addition, a plurality of adjacent sub-fire holes 41 of the two upper channels 21 form an overall annular flame, so that the formed overall annular flame is relatively stable and not prone to flameout, thereby improving the flameout resistance of the burner 100.

[0114] That is, the fire transfer gap 50 can connect multiple adjacent sub-fire holes 41 of the upper channel 21 together, and the fire transfer gap 50 can also connect two adjacent sub-fire holes 41 of the upper channel 21 together to generate an overall annular flame to improve the fire transfer ability and anti-fire ability of the burner 100.

[0115] In one embodiment, the lower plate 10 can be spaced apart from the partition plate 30 so that two adjacent lower channels 11 can be connected. The effect of the spaced apart arrangement of the lower plate 10 and the partition plate 30 is the same as the effect of the spaced apart arrangement of the upper plate 20 and the partition plate 30, and will not be described here to avoid redundancy.

[0116] The spacing d of the flame transfer gap 50 is selected from the range of [0.50 mm, 0.80 mm], so that two adjacent independent sub-fire holes 41 are connected together to ensure the flame transfer ability and anti-fire-out ability of the burner 100.

[0117] The spacing d of the spark gap 50 is selected from the range of 0.50 mm to 0.80 mm, that is, 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 ​​of 0.50 mm to 0.80 mm.

[0118] In one embodiment, the lower plate 10 is arranged in close contact with the partition plate 30, and the upper plate 20 is arranged at a distance from the partition plate 30. At this time, the two adjacent lower channels 11 in the lower plate 10 are not connected, and the two adjacent sub-fire holes 41 of the lower channel 11 are independently arranged and cannot transfer flames to each other. The two adjacent upper channels 21 in the upper plate 20 can be connected, that is, the two adjacent sub-fire holes 41 of the upper channel 21 can transfer flames to each other, so as to improve the flame transfer ability of the burner 100.

[0119] In another embodiment, the upper plate 20 and the partition plate 30 are arranged in close contact, and the lower plate 10 and the partition plate 30 are arranged at intervals. In this case, the two adjacent upper channels 21 in the upper plate 20 are not connected, and the two adjacent sub-fire holes 41 of the upper channel 21 are independently arranged and cannot transfer flames to each other. The two adjacent lower channels 11 in the lower plate 10 can be connected, that is, the two adjacent sub-fire holes 41 of the lower channel 11 can transfer flames to each other, so as to improve the flame transfer ability of the burner 100.

[0120] In other embodiments, the lower plate 10 is spaced from the partition plate 30, and the upper plate 20 is spaced from the partition plate 30. The lower plate 10 is spaced from the partition plate 30 so that two adjacent lower channels 11 can be connected, that is, two adjacent sub-fire holes 41 of the lower channel 11 can transfer flames to each other, so as to improve the flame transfer capability of the burner 100. In addition, a plurality of adjacent sub-fire holes 41 of the lower channel 11 form an overall annular flame, so that the formed overall annular flame is relatively stable and not prone to flameout, thereby improving the flameout resistance of the burner 100. The upper plate 20 is spaced from the partition plate 30 so that two adjacent upper channels 21 can be connected, that is, two adjacent sub-fire holes 41 of the two upper channels 21 can transfer flames to each other, so as to improve the flame transfer capability of the burner 100. In addition, a plurality of adjacent sub-fire holes 41 of the two upper channels 21 form an overall annular flame, so that the formed overall annular flame is relatively stable and not prone to flameout, thereby improving the flameout resistance of the burner 100.

[0121] It is worth noting that the partition plate 30 separates the fire 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 overall annular flame, and the flame is uniform and complete without the phenomenon of flame separation.

[0122] See also Figure 2 and Figure 3In some embodiments, the lower plate 10 includes a lower plate body 12, the upper plate 20 includes an upper plate body 22, the lower plate body 12 and the upper plate body 22 are substantially annular, the lower channels 11 are multiple and distributed along the inner circumference of the lower plate body 12, the upper channels 21 are multiple and distributed along the inner circumference of the upper plate body 22, the lower plate 10 includes a lower ejection pipe portion 13 connected to the lower plate body 12, the lower ejection pipe portion 13 is formed with a lower ejection pipe 131, the lower plate body 12 is formed with a lower air channel 71 connecting the lower ejection pipe 131 and the lower channel 11, the upper plate 20 includes a lower ejection pipe portion 13 connected to the lower plate body 12, and the lower ejection pipe portion 13 is formed with a lower ejection pipe 131. The lower plate body 12 is formed with a lower air channel 71 connecting the lower ejection pipe 131 and the lower channel 11, and the upper plate 20 is connected to the upper The upper ejector tube portion 23 connected to the plate body 22 forms an upper ejector pipe 231, and the upper plate body 22 forms an upper air duct 72 connecting the upper ejector pipe 231 and the upper hole 21, the lower ejector tube portion 13 cooperates with the upper ejector tube portion 23 to form the ejector tube 60 of the burner 100, the lower air duct 71 and the upper air duct 72 cooperate to form the air duct 70 of the burner 100, the ejector tube 60 is connected to the air duct 70 to form an ejector tube outlet 61, and the aperture of the fire hole 40 away from the ejector tube outlet 61 is larger than the aperture of the fire hole 40 close to the ejector tube outlet 61.

[0123] In this way, the flame of the fire hole 40 generated by the cooperation between the lower hole 11 and the upper hole 21 is cohesive, and the wrapping of the flame on the bottom of the pot is strengthened, thereby improving the combustion efficiency. In addition, the aperture size of the lower hole 11 and the upper hole 21 gradually decreases from the position far from the ejector tube outlet 61 to the position close to the ejector tube outlet 61, ensuring that the flame formed by the gas flowing through the fire hole 40 far from the ejector tube outlet is also larger, thereby ensuring that the flame of the fire hole 40 of the burner 100 is uniform.

[0124] Specifically, in one embodiment, the plurality of lower channels 11 are distributed along the inner circumference of the lower plate body 12 and arranged in a circular ring shape 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] The plurality of upper channels 21 are distributed along the inner circumference of the upper plate body 22 and are arranged in a circular ring shape below the upper plate 20 , so that the flames of the sub-fire holes 41 of the plurality of upper channels 21 are dense and vigorous.

[0126] That is, the multiple lower channels 11 and the multiple upper channels 21 cooperate to form the multiple fire holes 40, so that the multiple fire holes 40 are distributed in a circular shape, so that the flames of the fire holes 40 are cohesive, and the combustion efficiency is improved. In addition, the multiple fire holes 40 are distributed in a circular shape, which strengthens the wrapping of the flame on the bottom of the pot, improves the convection heat transfer coefficient between the flame and the bottom of the pot, and thus saves the use of gas.

[0127] In one embodiment, the ejector pipe 60 is connected to the gas passage 70 , and the ejector pipe 60 is used to mix the mixed gas of the fuel gas and the air evenly and transport the mixed gas to the gas passage 70 .

[0128] The gas passage 70 is connected to the fire hole 40 , and the gas passage 70 can mix the mixed gas of the fuel gas and the air evenly again, so as to generate a uniform flame through the fire hole 40 .

[0129] like Figure 2 As shown, in one embodiment, the aperture of the fire hole 40 close to the ejector tube outlet 61 is smaller, and the aperture of the fire hole 40 away from the ejector tube outlet 61 is larger, and the aperture of the fire hole 40 gradually increases from a position close to the ejector tube outlet 61 to a position M away from the ejector tube outlet 61, and the aperture of the fire hole 40 reaches a maximum at point M.

[0130] That is, the aperture size of the fire hole 40 gradually increases from a position close to the ejector tube outlet 61 to a position M far from the ejector tube outlet 61, to ensure that the flame generated by the gas flowing through the fire hole 40 at point M is also larger, thereby ensuring that the flame lengths generated by multiple fire holes 40 are equal, and further ensuring that the flames of the fire holes 40 of the burner 100 are uniform.

[0131] See also Figure 2 In some embodiments, the center line 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 quickly along the annular gas passage 70 after entering the gas passage 70 from the ejector tube 60, so as to continuously provide gas to the fire hole 40, increase the gas supply speed of the fire hole 40, and thus ensure that the flame of the fire hole 40 is continuous and uniform.

[0133] Specifically, in one embodiment, Figure 2 As shown, the gas passage 70 is arranged in a circular ring shape, and when the center line L of the ejector tube 60 is substantially tangent to the center circle R of the gas passage 70, the tangent point of the center line L and the center circle R is N, so that the gas can quickly enter the gas passage 70 from the ejector tube 60, thereby reducing the resistance of the inner wall of the gas passage 70 to the gas. In addition, after the gas enters the gas passage 70 from the ejector tube 60, it can flow quickly along the circular gas passage 70, thereby ensuring the gas supply speed of the fire hole 40, and further ensuring that the flame of the fire hole 40 is continuous and uniform.

[0134] See also Figure 2 and Figure 3 In some embodiments, the cross-sectional area of ​​the air channel 70 away from the ejector tube outlet 61 is smaller than the cross-sectional area of ​​the air channel 70 close to the ejector tube outlet 61 .

[0135] In this way, the cross-sectional area of ​​the gas duct 70 gradually increases from a position far away from the ejector tube outlet 61 to a position close to the ejector tube outlet 61, that is, the cross-sectional area of ​​the gas duct 70 close to the ejector tube outlet 61 is large, so that the gas is mixed evenly, the gas flow rate is relatively small, and the aperture of the fire hole 40 is small. The cross-sectional area of ​​the gas duct 70 far away from the ejector tube outlet 61 is small, the gas flow rate is relatively large, and the aperture of the fire hole 40 is large, thereby improving the uniformity of the flame of the fire hole 40.

[0136] Specifically, in one embodiment, the cross-sectional area of ​​the air duct 70 close to the ejector tube outlet 61 is larger, and the cross-sectional area of ​​the air duct 70 away from the ejector tube outlet 61 is smaller, and the cross-sectional area of ​​the air duct 70 gradually decreases from a position close to the ejector tube outlet 61 to a position M away from the ejector tube outlet 61, and the cross-sectional area of ​​the air duct 70 is the smallest at point M.

[0137] When the gas flow rate is constant, the cross-sectional area of ​​the gas passage 70 is larger at a position close to the ejector tube outlet 61, and relatively speaking, the gas flow rate is smaller at a position close to the ejector tube outlet 61, so that the gas and air are mixed evenly. The cross-sectional area of ​​the gas passage 70 is smaller at a position M far from the ejector tube outlet 61, and relatively speaking, the gas flow rate is larger at a position M far from the ejector tube outlet 61, so that the evenly mixed gas and air are quickly introduced to the fire hole 40.

[0138] It is worth noting that the cross-sectional area of ​​the air duct 70 gradually decreases from a position close to the ejector tube outlet 61 to a position M far from the ejector tube outlet 61, and the aperture size of the fire hole 40 gradually increases from a position close to the ejector tube outlet 61 to a position M far from the ejector tube outlet 61, so that the cross-sectional area of ​​the air duct 70 and the aperture size of the fire hole 40 cooperate with each other to improve the uniformity of the flame of the fire hole 40.

[0139] See also Fig. 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, and the partition plate body 31 is basically annular. The partition plate 30 also includes a flange 32 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 arranged corresponding to the ejector pipe outlet 61 to block the gas from entering the fire hole 40 corresponding to the flange 32 through the gas duct 70 from the ejector pipe outlet 61.

[0140] In this way, when all the fire holes 40 have the same size, the cross-sectional area of ​​the gas duct 70 gradually increases from a position far from the ejector tube outlet 61 to a position close to the ejector tube outlet 61, and the flange 32 is basically arc-shaped and is arranged corresponding to the ejector tube outlet 61 to block the gas from entering the fire hole 40 corresponding to the flange 32 through the gas duct 70 from the ejector tube outlet 61, thereby reducing the gas output of the fire hole 40 corresponding to the flange 32, and further reducing the flame length of the fire hole 40 corresponding to the flange 32 to ensure the uniformity of the flame of the fire hole 40.

[0141] Specifically, when the aperture sizes of the fire holes 40 are all the same, in one embodiment, the cross-sectional area of ​​the air duct 70 gradually decreases from a position close to the ejector tube outlet 61 to a position M away from the ejector tube outlet 61, and the uniformity of the flames of all the fire holes 40 can be ensured by setting a flange 32 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 fire holes 40 to ensure that the flame lengths of all fire holes 40 are the same, thereby ensuring the uniformity of the flames of the fire holes 40 .

[0143] In another embodiment, the flange 32 may be bent toward the upper plate 20 to block the flow of gas in different fire holes 40 to ensure that the flame lengths of all fire holes 40 are the same, thereby ensuring the uniformity of the flames of the fire holes 40 .

[0144] In other embodiments, the flange 32 can be bent toward the lower plate 10 and toward the upper plate 20 at the same time to ensure that the flame lengths of all the fire holes 40 are the same, thereby ensuring the uniformity of the flames of the fire holes 40 .

[0145] See also Fig.10 In some embodiments, the arc angle of the flange 32 is 0 to 180 degrees.

[0146] In this way, by providing 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, and can be used to block the gas from entering the fire hole 40 corresponding to the flange 32 through the gas channel 70 from the ejector pipe outlet 61. That is, the flange 32 can be made of a high temperature resistant 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 an aluminum alloy material, a copper alloy material, or other materials, which are not specifically limited here.

[0148] Preferably, in one embodiment, Fig.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 fire hole 40 corresponding to the flange 32 through the gas channel 70 from the ejector pipe outlet 61, reduce the gas output of the fire hole 40 corresponding to the flange 32, and further reduce the flame length of the fire hole 40 corresponding to the flange 32 to ensure the uniformity of the flame of the fire hole 40.

[0149] The arc angle A is selected from the range of 0 to 180 degrees, that is, 0°≤A≤180°. In an example, the arc angle A can be 0°, 45°, 90°, 120°, 135°, 150°, 180° or other values ​​from 0 to 180°.

[0150] In certain embodiments, the arc angle of the flange is 0 to 150 degrees.

[0151] In this way, the flame length of the fire hole 40 can be further accurately adjusted, thereby ensuring the uniformity of the flame of the fire hole 40 .

[0152] Specifically, in one embodiment, Fig.10 As shown, the arc angle of the flange 32 on the partition plate 30 is B.

[0153] It can be understood that the arc angle B is selected from the range of 0 degrees to 150 degrees to block the gas from entering the fire hole 40 corresponding to the flange 32 through the gas duct 70 from the ejector pipe outlet 61, reducing the gas output of the fire hole 40 corresponding to the flange 32, and then reducing the flame length of the fire hole 40 corresponding to the flange 32 to ensure the uniformity of the flame of the fire hole 40.

[0154] In one embodiment, the arc angle B is selected from the range of 0 to 150 degrees, that is, 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 amount of gas in the fire hole 40 can be changed by changing the length or inclination angle of the flange 32 in different positions of the partition plate 30, thereby ensuring that the supply amount of gas in the fire hole 40 is the same, thereby ensuring the uniformity of the flame of the fire 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 supply amount of gas in the fire hole 40 is the same, thereby ensuring the uniformity of the flame of the fire hole 40, and no specific limitation is made here.

[0157] See also 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 radial direction of the upper plate body 22.

[0158] In this way, the flame of the fire hole 40 formed by the cooperation between the lower hole 11 and the upper hole 21 is concentrated, so that the flame is more vigorous, thereby improving the combustion efficiency of the fuel gas.

[0159] Specifically, 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 the angle E, and the corresponding radial direction of one of the lower plate bodies 12 is the dotted line direction of the angle E.

[0160] The depth direction of the lower channel 11 is inclined relative to the radial direction of the lower plate body 12, so that the flames of the sub-fire holes 41 of the lower channel 11 gather toward the inner circumference of the lower plate body 12, making the flames more vigorous and improving the combustion efficiency of the fuel gas.

[0161] like Figure 2 As shown, the angle formed by the depth direction of the upper channel 21 and the radial direction of the upper plate body 22 is F, wherein the depth direction of one of the upper channels 21 is the solid line direction of the angle F, and the corresponding radial direction of one of the upper plate bodies 22 is the dotted line direction of the angle F.

[0162] The depth direction of the upper channel 21 is inclined relative to the radial direction of the upper plate body 22, so that the flames of the sub-fire holes 41 of the upper channel 21 gather toward the inner circumference of the upper plate body 22, making the flames more vigorous and improving the combustion efficiency of the fuel gas.

[0163] In summary, the flame of the fire hole 40 formed by the cooperation between the lower hole 11 and the upper hole 21 is concentrated, making the flame more vigorous, thereby improving the combustion efficiency of the fuel gas.

[0164] In some embodiments, the lower plate body 12 includes a lower plate inner ring portion 121, the lower channel 11 is formed in the lower plate inner ring portion 121, and the lower plate inner ring portion 121 is arched radially from the outside to the inside toward the upper plate 20, and the upper plate body 22 includes an upper plate inner ring portion 221, the upper channel 21 is formed in the upper plate inner ring portion 221, and the upper plate inner ring portion 221 is arched radially from the outside to the inside toward the direction away from the lower plate 10.

[0165] In this way, the lower plate inner ring portion 121 and the upper plate inner ring portion 221 are arranged in the same direction to ensure mutual cooperation to form a plurality of fire holes 40 that are oriented in the same direction as the lower channel 11 and the upper channel 21 and face upward, so that the flame of the fire hole 40 is closer to the bottom of the pot, thereby improving the heat transfer efficiency between the flame and the bottom of the pot.

[0166] Specifically, Figure 1 and Figure 3 As shown, in one embodiment, the lower plate inner ring portion 121 is arranged in a circular ring shape, and the lower plate inner ring portion 121 is arched radially from the outside to the inside toward the upper plate 20 to support the upper plate inner ring portion 221 to improve the stability of the upper plate inner ring portion 221.

[0167] like Figure 1 and Figure 2As shown, the upper plate inner ring portion 221 is arranged in a circular ring shape, and the upper plate inner ring portion 221 is arched radially from the outside to the inside in a direction away from the lower plate 10, and is used to cooperate with the lower plate inner ring portion 121 to form a plurality of fire holes 40 distributed in a circular ring shape, so that the fire holes 40 are closer to the bottom of the pot, so as to improve the heat transfer efficiency between the flame and the bottom of the pot.

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, the oil cup 210 is arranged below the burner 100, and the burner assembly 200 also includes a guide plate 220 arranged near the burner 100, and the guide plate 220 is configured to guide the oil droplets falling into the burner assembly 200 to slide down the oil cup 210 during the cooking process.

[0169] In this way, the burner assembly 200 is ensured to be clean and tidy during the cooking process, the cleaning steps are reduced, and the user experience is improved.

[0170] Specifically, in one embodiment, the guide plate 220 is arranged in a funnel shape between multiple burners 100 (such as an inner ring burner and an outer ring burner), and can be used to direct 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.

[0171] In addition, the guide plate 220 is arranged in a funnel shape between multiple burners 100 (such as an inner ring burner and an outer ring burner), which can be used to increase the space between the multiple burners 100, ensure the supply of secondary air, and improve the combustion efficiency of the burner assembly 200.

[0172] The guide plate 220 is arranged in a funnel shape between the multiple burners 100, and can also be used to shield the internal structure of the burner assembly 200, so that the burner assembly 200 has a beautiful and simple appearance.

[0173] In one embodiment, the oil cup 210 can be used to hold oil drops flowing down the guide plate 220 during the cooking process, thereby improving the cleanliness of the kitchen and thus improving the user experience.

[0174] See also Fig.13 and Fig.14 In some embodiments, the burner assembly 200 further includes a bracket 230 , and at least one burner 100 and an oil cup 210 are fixed on the bracket 230 .

[0175] In this way, the stability of the burner assembly 200 is improved, and the production cost of the bracket 230 is low, simple and convenient.

[0176] 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, which can be used to hold the oil cup 210 , thereby ensuring that the burner assembly 200 is clean and sanitary.

[0177] In one embodiment, the bracket 230 includes a plurality of claws, which can be used to fix and support at least one burner 100 and an oil cup 210, thereby ensuring that the burner assembly 200 works stably and improving the safety of cooking in the kitchen.

[0178] In one embodiment, the bracket 230 can be integrally formed of an aluminum alloy material to reduce weight and production costs. In addition, the bracket 230 can be used to fix multiple parts to improve the installation efficiency of the burner assembly 200.

[0179] In one embodiment, the bracket 230 may be formed by a die-casting process, or may be formed by other processes, which are not specifically limited herein.

[0180] In one embodiment, the burner assembly 200 further includes a fixing plate 240 and an ignition needle 250 .

[0181] The fixing plate 240 can be fixed to the bracket 230 by screws to reinforce the burner 100 and further improve the stability of the burner 100 .

[0182] The ignition needle 250 can be installed in cooperation with the guide plate 220 to be fixed on the bracket 230, so as to generate an electric arc to ignite the gas at the fire hole 40 of the burner 100, thereby generating a uniform flame.

[0183] See also Fig.11 and Fig.12 In some embodiments, the partition plate 30 is formed with a protrusion 33 configured to contact the arc generated by the ignition needle 250 .

[0184] In this way, the partition plate 30 forms a protrusion 33, which contacts the arc generated by the ignition needle 250 to prevent the arc from running away, thereby increasing the ignition success rate and improving the user experience.

[0185] Specifically, the protrusion 33 is arranged on the partition plate 30, and can be used to attract the arc generated by the ignition needle 250, so that the 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.

[0186] It can be understood that the upper plate 20 and the partition plate 30 form a fire transfer gap 50 between two adjacent upper channels 21. When the arc generated by the ignition needle 250 contacts the protrusion 33, the efficiency of the fire hole 40 in forming an overall annular flame can be improved, thereby improving the ignition success rate of the burner 100.
