Description

Technical Field

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

[0002] The burner of the related art includes an upper plate and a lower plate, the upper plate is convex upward to form an upper fire hole, and the lower plate is concave downward to form a lower fire hole, and the upper fire hole and the lower fire hole are staggered to avoid the phenomenon of flameout noise, etc. However, the area of ​​the fire hole is small, which makes it difficult to obtain a larger flame. Summary of the invention

[0003] Embodiments of the present invention provide a burner and a stove.

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

[0005] Lower plate; and

[0006] An upper plate is arranged on the lower plate, the lower plate is formed with a lower channel, the upper plate is formed with an upper channel corresponding to the lower channel, the lower channel and the upper channel are directly opposite to form a fire hole of the burner, 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°).

[0007] In the burner, the upper hole of the upper plate and the lower hole of the lower plate are arranged opposite to each other, so that the fire holes of the burner are formed opposite to each other, thereby increasing the total area of ​​the fire holes of the burner, thereby increasing the flame intensity and load upper limit of the burner. In addition, the fire holes of the burner are inclined inwardly into a cone shape, thereby ensuring the flame gathering effect of the burner, thereby increasing the flame intensity and heating efficiency of the burner.

[0008] In certain embodiments, the angle θ is in the range of (0°, 60°).

[0009] In this way, the flame focusing ability of the burner is ensured, thereby improving the heating efficiency.

[0010] In certain embodiments, the angle θ is 40°.

[0011] 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.

[0012] In certain embodiments, the burner comprises:

[0013] A partition plate is disposed between the lower plate and the upper plate and separates the lower hole channel from the upper hole channel.

[0014] In this way, the partition plate separates the fire hole into a lower channel and an upper channel, which is equivalent to dividing the fire hole into two independent sub-fire holes. The cross-sectional area of ​​each sub-fire hole becomes smaller, so the depth of the sub-fire hole becomes deeper. This can prevent the flame from entering the gas channel through the sub-fire hole at the moment the gas valve is closed and causing flameout noise. In addition, the equivalent cross-sectional area of ​​the fire hole does not change, which can ensure that the burner has a larger flame.

[0015] In certain embodiments, a fire transfer gap is formed between the upper plate and the partition plate.

[0016] In this way, two adjacent independent sub-fire holes are connected together, thereby ensuring the formation of an integral flame, thereby improving the flame transfer ability and anti-fire-out ability of the burner.

[0017] 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 transfer gap between the upper plate and the partition plate.

[0018] In this way, the inner ring of the upper plate and the adjacent sub-fire holes between the partition plate can transfer flames. In addition, during the combustion process, air can reach the fire holes through the flame transfer gap, effectively supplementing the secondary air required for combustion, thereby improving the combustion efficiency of the burner.

[0019] In certain embodiments, the outer ring portion, the partition plate and the lower plate are tightly fixed at lower portions by spot welding.

[0020] In this way, the fire holes are stably arranged, thereby providing stability for the burner and further providing a stable and uniform flame.

[0021] In certain embodiments, the arc of the spark transfer gap distributed at the inner edge of the inner ring portion is [0°, 360°].

[0022] 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.

[0023] In some embodiments, the lower plate, the partition plate and the upper plate are integrally formed of stainless steel sheets, the lower plate is concave to form an arc-shaped lower channel, the upper plate is convex to form an arc-shaped upper channel, the lower channel and the upper channel form a fire hole, and the fire hole is elliptical.

[0024] In this way, the lower plate, the partition plate and the upper plate are integrally formed of stainless steel sheets, making the inner wall of the burner relatively smooth, thereby reducing air flow resistance and effectively ensuring the supply of air required for complete combustion of the gas. The burner has a simple structure and low cost.

[0025] 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.

[0026] In this way, the flange is basically in a circular shape to block the gas from entering the fire hole corresponding to the flange from the gas channel, reduce the gas output of the fire hole corresponding to the flange, and then reduce the flame length of the fire hole corresponding to the flange to ensure the uniformity of the flame of the fire hole.

[0027] In certain embodiments, the separator plate is formed with a protrusion configured to contact an arc generated by an ignition needle.

[0028] 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.

[0029] An embodiment of the present invention provides a stove, which includes the burner described in the above embodiment.

[0030] In this way, the upper hole of the upper plate and the lower hole of the lower plate of the cooker are arranged opposite to each other, so that the fire holes of the burner are formed opposite to each other, thereby increasing the total area of ​​the fire holes of the burner, thereby increasing the upper load limit of the burner. In addition, the fire holes of the burner are 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.

[0049] See also Figures 1 to 5 A burner 100 provided in an embodiment of the present invention includes a lower plate 10 and an upper plate 20 disposed on the lower plate 10. The lower plate 10 is formed with a lower channel 11, and the upper plate 20 is formed with an upper channel 21 corresponding to the lower channel 11. The lower channel 11 and the upper channel 21 are opposite to form a fire hole 30 of the burner 100. The depth direction of the fire hole 30 forms an angle θ with the plane where the upper plate 20 is located, and the range of the angle θ is (0°, 90°).

[0050] The burner 100, the upper channel 21 of the upper plate 20 and the lower channel 11 of the lower plate 10 are arranged opposite to each other, so that the fire holes 30 of the burner 100 are formed opposite to each other, thereby increasing the total area of ​​the fire holes 30 of the burner 100, and further increasing the flame intensity and load upper limit of the burner 100. In addition, the fire holes 30 of the burner 100 are inclined inwardly into a cone shape, thereby ensuring the flame gathering effect of the burner 100, and further increasing the flame intensity and heating efficiency of the burner 100.

[0051] Specifically, the lower plate 10 can be used to form the fire hole 30 , so the lower plate 10 can be made of a high temperature resistant and corrosion resistant material.

[0052] 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.

[0053] Similarly, the upper plate 20 can be used to form the fire hole 30 with the lower plate 10, so the upper plate 20 can be made of a high temperature resistant and corrosion resistant material.

[0054] 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.

[0055] 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 30. Compared with a single lower channel 11 or a single upper channel 21 arranged in a staggered manner, the total area of ​​the fire hole 30 is increased, so that the combustion amount of the gas is increased, thereby improving the flame intensity of the burner 100.

[0056] In one embodiment, the angle θ formed by the depth direction of the fire hole 30 and the plane where the upper plate 20 is located is in the range of (0°, 90°), so that the fire hole 30 of the burner 100 is inclined inward into a cone shape, thereby ensuring the flame focusing 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.

[0057] It can be understood that when the angle formed by the depth direction of the fire hole 30 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.

[0058] 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°.

[0059] In certain embodiments, the angle θ is in the range of (0°, 60°).

[0060] In this way, the flame focusing ability of the burner 100 is ensured, thereby improving the heating efficiency.

[0061] Specifically, in one embodiment, preferably, the angle θ formed by the depth direction of the fire hole 30 and the plane where the upper plate 20 is located is in the range of (0°, 60°), so that the fire hole 30 of the burner 100 is inclined inwardly into a cone shape, thereby ensuring that the flame formed by the fire hole 30 of the burner 100 better covers the bottom of the cooking utensil, thereby improving the heating rate of the burner 100.

[0062] It can be understood that when the angle formed by the depth direction of the fire hole 30 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.

[0063] 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°.

[0064] In certain embodiments, the angle θ is 40°.

[0065] In this way, it is ensured that the flame intensity formed by the burner 100 is relatively large, so that the heating effect of the bottom of the cooking utensil is better.

[0066] Specifically, in one embodiment, preferably, the angle θ formed by the depth direction of the fire hole 30 and the plane where the upper plate 20 is located can be 40°. While ensuring that the fire hole 30 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.

[0067] 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.

[0068] See also Figure 1 and Figure 3 In some embodiments, the burner 100 includes a partition plate 40 , which is disposed between the lower plate 10 and the upper plate 20 and separates the lower channel 11 from the upper channel 21 .

[0069] In this way, the partition plate 40 separates the fire hole 30 into the lower channel 11 and the upper channel 21, which is equivalent to dividing the fire hole 30 into two independent sub-fire holes 31. The cross-sectional area of ​​each sub-fire hole 31 becomes smaller, so the depth of the sub-fire hole 31 becomes deeper. In this way, the flame can be prevented from entering the gas channel through the sub-fire hole 31 at the moment when the gas valve is closed, causing the flameout noise. In addition, the equivalent cross-sectional area of ​​the fire hole 30 is not changed, which can ensure that the burner 100 has a larger flame.

[0070] Specifically, the partition plate 40 is disposed between the lower plate 10 and the upper plate 20 to separate each fire hole 30 into two sub-fire holes 31 , so that the sub-fire holes 31 located on the upper and lower sides of the partition plate 40 are independent of each other.

[0071] It can be understood that the cross-sectional area of ​​the sub-fire hole 31 is relatively reduced, and the depth of the sub-fire hole 31 is relatively deepened. At the moment when the gas valve is closed, the path of the flame return gas channel becomes relatively long. 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.

[0072] It is worth noting that the partition plate 40 separates the fire hole 30 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.

[0073] That is, the partition plate 40 is disposed between the lower plate 10 and the upper plate 20 and does not affect the flame size of the fire hole 30 , thereby maintaining the burner 100 at a larger flame intensity.

[0074] The partition plate 40 is disposed at the fire hole 30, so the partition plate 40 can be made of a high temperature resistant and corrosion resistant material. In one embodiment, the material of the partition plate 40 can be a stainless steel partition plate. In other embodiments, the material of the partition plate 40 can be an aluminum alloy partition plate, a copper alloy partition plate, or a partition plate of other materials, which is not specifically limited here.

[0075] In certain embodiments, a fire transfer gap 50 is formed between the upper plate 20 and the partition plate 40 .

[0076] In this way, two adjacent independent sub-fire holes 31 are connected together, thereby ensuring the formation of an integral flame, thereby improving the flame transfer capability of the burner 100 .

[0077] Specifically, in one embodiment, the flame transfer gap 50 may be a channel with a certain distance d, which can be used to transfer flames.

[0078] It can be understood that the upper plate 20 and the partition plate 40 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.

[0079] 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 the burner 100 .

[0080] 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 .

[0081] 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.

[0082] See also Figure 6 In some embodiments, the upper plate 20 is annular and includes an inner ring portion 22 and an outer ring portion 23. The inner ring portion 22 protrudes upward relative to the outer ring portion 23 and is spaced apart from the partition plate 40 to form a fire transfer gap 50 between the upper plate 20 and the partition plate 40.

[0083] In this way, the adjacent sub-fire holes between the inner ring portion 22 of the upper plate 20 and the partition plate 40 can transfer flames. In addition, during the combustion process, air can reach the fire holes 30 through the flame transfer gap 50, effectively supplementing the secondary air required for combustion, thereby improving the combustion efficiency of the burner 100.

[0084] Specifically, in one embodiment, the inner ring portion 22 protrudes upward relative to the outer ring portion 23, so that the inner ring portion 22 and the partition plate 40 are spaced apart to form a flame transfer gap 50 to ensure that flames can be transferred between two adjacent upper channels 21 in the upper plate 20.

[0085] The inner ring portion 22 protrudes upward relative to the outer ring portion 23 so that the outer ring portion 23 is closely arranged with the partition plate 40 to form a closed environment to prevent the flame of the upper channel 21 from flowing back along the outer ring portion 23 from the fire transfer gap 50 to cause safety hazards.

[0086] 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 .

[0087] 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 22, 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 22, 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 40, thereby improving the fire transfer ability and anti-fire ability of the burner 100.

[0088] In one embodiment, the lower plate 10 is arranged in close contact with the partition plate 40, and the upper plate 20 is arranged at a distance from the partition plate 40. At this time, the two adjacent lower channels 11 in the lower plate 10 are not connected, and the two adjacent sub-fire holes 31 of the lower channels 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 31 of the upper channels 21 can transfer flames to each other, so as to improve the flame transfer ability of the burner 100.

[0089] In another embodiment, the upper plate 20 is arranged in close contact with the partition plate 40, and the lower plate 10 is arranged at a distance from the partition plate 40. In this case, two adjacent upper channels 21 in the upper plate 20 are not connected, and two adjacent sub-fire holes 31 in the upper channels 21 are arranged independently of each other and cannot transfer flames to each other. Two adjacent lower channels 11 in the lower plate 10 can be connected, that is, two adjacent sub-fire holes 31 in the lower channels 11 can transfer flames to each other, so as to improve the flame transfer capability of the burner 100.

[0090] In other embodiments, the lower plate 10 is spaced from the partition plate 40, and the upper plate 20 is spaced from the partition plate 40. The lower plate 10 is spaced from the partition plate 40 so that two adjacent lower channels 11 can be connected, that is, two adjacent sub-fire holes 31 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 31 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 40 so that two adjacent upper channels 21 can be connected, that is, two adjacent sub-fire holes 31 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 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.

[0091] See also Figure 3 and Figure 4 In some embodiments, the outer ring portion 23, the partition plate 40 and the lower plate 10 are tightly fixed at the lower portion by spot welding.

[0092] In this way, the flame holes 30 are stably arranged, thereby providing stability for the burner 100 and further providing a stable and uniform flame.

[0093] Specifically, in one embodiment, the outer ring portion 23 and the partition plate 40 may be tightly fixed by a welding process to improve the stability of the outer ring portion 23 and the partition plate 40 .

[0094] It is understandable that the outer ring portion 23 and the partition plate 40 can be tightly fixed by welding process, so that the fire transfer gap 50 cannot pass through the outer ring portion 23, so as to avoid the flame of the upper channel 21 from the fire transfer gap 50 along the outer ring portion 23 backflow airway, causing safety hazards.

[0095] In one embodiment, the partition plate 40 and the lower plate 10 may be closely fixed by a welding process to improve the stability of the partition plate 40 and the lower plate 10 .

[0096] It can be understood that the partition plate 40 and the lower plate 10 can be tightly fixed by a welding process, so that no fire transfer gap 50 is formed between the lower plate 10 and the partition plate 40, further enhancing the stability and supporting strength of the lower plate 10.

[0097] In summary, the outer ring portion 23, the partition plate 40 and the lower plate 10 can be connected and fixed by spot welding to ensure that the burner 100 forms a stable fire hole structure, thereby ensuring the uniformity and strength of the flame.

[0098] In one embodiment, the lower plate 10 and the upper plate 20 may also be connected by a screwing process to form the burner 100. In another embodiment, the lower plate 10 and the upper plate 20 may also be connected by a pressing 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.

[0099] See also Figure 6 and Figure 7 In some embodiments, the arc of the fire transfer gap 50 distributed at the inner edge of the inner ring portion 22 is [0°, 360°].

[0100] 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.

[0101] 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 31 are in an overall annular shape, thereby improving the stability of the flames of the upper channels 31 and further improving the flame stability of the burner 100.

[0102] 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 .

[0103] In one embodiment, the arc of the fire transfer gap 50 distributed at the inner edge of the inner ring portion 22 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°.

[0104] 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 30 , thereby making the burner 100 have stronger fire transfer ability and anti-fire ability.

[0105] In some embodiments, the lower plate 10, the partition plate 40 and the upper plate 20 are integrally formed of stainless steel thin plates. The lower plate 10 is concave to form an arc-shaped lower channel 11, and the upper plate 20 is convex to form an arc-shaped upper channel 21. The lower channel 11 and the upper channel 21 form a fire hole 30, and the fire hole 30 is elliptical.

[0106] In this way, the lower plate 10, the partition plate 40 and the upper plate 20 are integrally formed of stainless steel thin plates, 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. The burner 100 has a simple structure and low cost.

[0107] Specifically, in one embodiment, the lower plate 10 can be used to form the fire hole 30, 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.

[0108] In one embodiment, the partition plate 40 can be used to separate the fire hole 30, so the partition plate 40 can be made of a high temperature resistant and corrosion resistant material. That is, the partition plate 40 can be integrally formed with a stainless steel material to shorten the production time and save production costs. In other embodiments, the partition plate 40 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.

[0109] Similarly, the upper plate 20 can be used to form the fire hole 30 with the lower plate 10, 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.

[0110] In one embodiment, the lower plate 10, the partition plate 40 and the upper plate 20 can be formed into a burner 100 by integrally forming stainless steel, so that the burner 100 is thin and the inner wall is smooth, 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, the partition plate 40 and the upper plate 20 can 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 evenly heated, thereby improving the uniformity of the flames of the lower channel 11 and the upper channel 21.

[0111] In one embodiment, please combine Figure 1 The lower channel 11 is arc-shaped and concave to ensure that the lower channel 11 has a suitable inner cavity space, thereby ensuring the safe and rapid transportation of the gas.

[0112] Similarly, the upper hole 21 is convex in an arc shape to ensure that the upper hole 21 has a suitable inner cavity space, thereby ensuring safe and rapid transportation of the gas.

[0113] It can be understood that the lower channel 11 and the upper channel 21 cooperate to form an elliptical fire hole 30 to ensure that the cross-sectional area of ​​the fire hole 30 is larger, and at the same time the fire hole 30 delivers a larger amount of fuel gas, thereby ensuring a larger flame intensity, thereby improving flame uniformity and heating efficiency.

[0114] In some embodiments, the lower plate 10 and the upper plate 20 are substantially annular, the lower channels 11 are multiple and distributed along the inner circumference of the lower plate 10 , and the upper channels 21 are multiple and distributed along the inner circumference of the upper plate 20 .

[0115] In this way, the flame of the fire hole 30 formed by the cooperation between the lower channel 11 and the upper channel 21 is cohesive, while the flame wrapping around the bottom of the pot is strengthened, the convection heat transfer coefficient is improved, the combustion efficiency is improved, the gas usage is saved, and it is green and environmentally friendly.

[0116] Specifically, in one embodiment, the plurality of lower channels 11 are distributed along the inner circumference of the lower plate 10 and arranged in a circular ring shape on the lower plate 10 , so that the flames of the sub-fire holes 31 of the plurality of lower channels 11 are dense and vigorous.

[0117] The plurality of upper channels 21 are distributed along the inner circumference of the upper plate 20 and are arranged in a circular ring shape below the upper plate 20 , so that the flames of the sub-fire holes 31 of the plurality of upper channels 21 are dense and vigorous.

[0118] That is, the multiple lower channels 11 and the multiple upper channels 21 cooperate to form the multiple fire holes 30, so that the multiple fire holes 30 are distributed in a circular ring shape, so that the flames of the fire holes 30 are cohesive, and the combustion efficiency is improved. In addition, the multiple fire holes 30 are distributed in a circular ring 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.

[0119] In some embodiments, the depth direction of the lower channel 11 is inclined relative to the radial direction of the lower plate 10 and / or the depth direction of the upper channel 21 is inclined relative to the radial direction of the upper plate 20 .

[0120] In this way, the flame of the fire hole 30 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.

[0121] Specifically, Figure 7 As shown, the angle between the depth direction of the lower channel 11 and the radial direction of the lower plate 10 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 plates 10 is the dotted line direction of the angle E.

[0122] The depth direction of the lower channel 11 is inclined relative to the radial direction of the lower plate 10, so that the flames of the sub-fire holes 31 of the lower channel 11 gather toward the inner circumference of the lower plate 10, making the flames more vigorous and improving the combustion efficiency of the fuel gas.

[0123] like Figure 6 As shown, the angle between the depth direction of the upper channel 21 and the radial direction of the upper plate 20 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 plates 20 is the dotted line direction of the angle F.

[0124] The depth direction of the upper channel 21 is inclined relative to the radial direction of the upper plate 20, so that the flames of the sub-fire holes 31 of the upper channel 21 gather toward the inner circumference of the upper plate 20, making the flames more vigorous and improving the combustion efficiency of the fuel gas.

[0125] In summary, the flame of the fire hole 30 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.

[0126] In some embodiments, the lower plate 10 includes a lower plate inner ring portion 12, the lower channel 11 is formed in the lower plate inner ring portion 12, the lower plate inner ring portion 12 is arched radially from the outside to the inside toward the upper plate 20, and the upper plate 20 includes an inner ring portion 22, the upper channel 21 is formed in the inner ring portion 22, and the inner ring portion 22 is arched radially from the outside to the inside toward the direction away from the lower plate 10.

[0127] In this way, the lower plate inner ring portion 12 and the inner ring portion 22 are arranged in the same direction to ensure cooperation with each other to form a plurality of fire holes 30 that are oriented in the same direction as the lower channel 11 and the upper channel 21 and face upward, so that the flames of the fire holes 30 are closer to the bottom of the pot, thereby improving the heat transfer efficiency between the flame and the bottom of the pot.

[0128] Specifically, Figure 6 and Figure 7 As shown, in one embodiment, the lower plate inner ring portion 12 is arranged in a circular ring shape, and the lower plate inner ring portion 12 is arched radially from the outside to the inside toward the upper plate 20 to support the inner ring portion 22 to improve the stability of the inner ring portion 22.

[0129] like Figure 6 and Figure 7 As shown, the inner ring portion 22 is arranged in a circular ring shape, and the inner ring portion 22 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 inner ring portion 12 of the lower plate to form a plurality of fire holes 30 distributed in a circular ring shape, so that the fire holes 30 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.

[0130] See also Figure 6 and Figure 7 In some embodiments, the lower plate 10 includes a lower ejector tube portion 13 connected to the lower plate inner ring portion 12, the lower ejector tube portion 13 is formed with a lower ejector pipe 131, the lower plate 10 is formed with a lower air duct 71 connecting the lower ejector pipe 131 with the lower channel 11, the upper plate 20 includes an upper ejector tube portion 24 connected to the upper plate 20, the upper ejector tube portion 24 is formed with an upper ejector pipe 241, the upper plate 20 is formed with an upper air duct 72 connecting the upper ejector pipe 241 with the upper channel 21, the lower ejector tube portion 13 and the upper ejector tube portion 24 cooperate to form an ejector tube 60 of the burner 100, the lower air duct 71 and the upper air duct 72 cooperate to form an 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 30 away from the ejector tube outlet 61 is larger than the aperture of the fire hole 30 close to the ejector tube outlet 61.

[0131] In this way, the aperture size of the fire hole 30 gradually decreases from a position far away from the ejector tube outlet 61 to a position close to the ejector tube outlet 61, ensuring that the flame generated by the gas flowing through the fire hole 30 far away from the ejector tube outlet 61 is also larger, thereby ensuring that the flame of the fire hole 30 of the burner 100 is uniform.

[0132] Specifically, 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 .

[0133] The gas passage 70 is connected to the fire hole 30 , 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 30 .

[0134] like Figure 6 As shown, in one embodiment, the aperture of the fire hole 30 close to the ejector tube outlet 61 is smaller, and the aperture of the fire hole 30 away from the ejector tube outlet 61 is larger, and the aperture of the fire hole 30 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 30 reaches a maximum at point M.

[0135] That is, the aperture size of the fire hole 30 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 30 at point M is also larger, thereby ensuring that the flame lengths generated by multiple fire holes 30 are equal, and further ensuring that the flames of the fire holes 30 of the burner 100 are uniform.

[0136] See also Figure 6 In some embodiments, the center line L of the ejector tube 60 passes through the center O of the center circle R of the airway 70 .

[0137] In this way, the gas can flow evenly along the annular gas passage 70 after entering the gas passage 70 from the ejector tube 60 , which is beneficial to improving the ignition success rate of the protrusion 43 .

[0138] Specifically, in one embodiment, Figure 6 As shown, the gas passage 70 is arranged in a circular ring shape, and the center line L of the ejector tube 60 passes through the center O of the center circle R of the gas passage 70, so that the gas and air mixture flows evenly toward both sides of the gas passage 70 after entering the gas passage 70 from the ejector tube 60, ensuring that the gas and air mixture is evenly distributed in the gas passage 70, making it easier for the discharge arc to ignite the gas and air mixture to produce an overall circular flame, thereby improving the ignition success rate of the protrusion 43.

[0139] See also Figure 8 and Fig. 9 In some embodiments, the partition plate 40 includes a partition plate body 41 located between the lower plate 10 and the upper plate 20, and the partition plate body 41 is basically annular. The partition plate 40 also includes a flange 42 bent from the outer peripheral edge of the partition plate body 41 toward the lower plate 10. The flange 42 is basically arc-shaped and is arranged corresponding to the ejector pipe outlet 61 to block the gas from entering the fire hole 30 corresponding to the flange 42 through the gas duct 70 from the ejector pipe outlet 61.

[0140] In this way, when the cross-sectional areas of all gas passages 70 are the same and the sizes of all fire holes 30 are the same, the flange 42 is basically arc-shaped and is arranged corresponding to the ejector tube outlet 61 to block the gas from entering the fire hole 30 corresponding to the flange 42 through the gas passage 70 from the ejector tube outlet 61, thereby reducing the gas output of the fire hole 30 corresponding to the flange 42, and further reducing the flame length of the fire hole 30 corresponding to the flange 42 to ensure the uniformity of the flame of the fire hole 30.

[0141] Specifically, in one embodiment, the pressure of the fuel gas and air mixture near the ejector tube outlet 61 is greater and the flow rate is faster. When the cross-sectional areas of all gas passages 70 are the same and the sizes of all fire holes 30 are the same, the flame generated by the fire holes 30 near the ejector tube outlet 61 is longer.

[0142] Similarly, if Fig. 9 As shown, the pressure of the fuel gas and air mixture away from the ejector tube outlet 61 (such as point M) is smaller and the flow rate is slower. When the cross-sectional areas of all gas ducts 70 are the same and the sizes of all fire holes 30 are the same, the flame produced by the fire holes 30 close to the ejector tube outlet 61 is shorter.

[0143] In summary, the embodiment of the present invention can set an arc-shaped flange 42 on the partition plate 40 to block the gas from entering the fire hole 30 corresponding to the flange 42 through the gas duct 70 from the ejector pipe outlet 61, thereby reducing the gas output of the fire hole 30 corresponding to the flange 42 to ensure the uniformity of the flames of all the fire holes 30.

[0144] In one embodiment, the flange 42 can be bent toward the lower plate 10 to block the flow of gas in different fire holes 30 to ensure that the flame lengths of all fire holes 30 are the same, thereby ensuring the uniformity of the flames of the fire holes 30 .

[0145] In another embodiment, the flange 42 may be bent toward the upper plate 20 to block the flow of gas in different fire holes 30 to ensure that the flame lengths of all fire holes 30 are the same, thereby ensuring the uniformity of the flames of the fire holes 30 .

[0146] In other embodiments, the flange 42 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 30 are the same, thereby ensuring the uniformity of the flames of the fire holes 30 .

[0147] See also Figure 8 and Fig. 9 In some embodiments, the arc angle A of the flange 42 is (0°, 60°].

[0148] In this way, by providing a flange 42 with a certain arc angle A on the partition plate 40 to adjust the flame length of the fire hole 30 , the uniformity of the flame of the fire hole 30 is ensured.

[0149] Specifically, the flange 42 is located on the partition plate 40 and connected to the partition plate body 41, and can be used to block the gas from entering the fire hole 30 corresponding to the flange 42 through the gas channel 70 from the ejector pipe outlet 61. That is, the flange 42 can be made of a high temperature resistant and corrosion resistant material. In one embodiment, the flange 42 can be made of stainless steel. In other embodiments, the flange 42 can be made of an aluminum alloy material, a copper alloy material, or other materials, which are not specifically limited here.

[0150] Preferably, in one embodiment, Fig. 9 As shown, the arc angle A of the flange 42 on the partition plate 40 is selected from the range of (0°, 60°] to block the gas from entering the fire hole 30 corresponding to the flange 42 through the gas channel 70 from the ejector pipe outlet 61, reduce the gas output of the fire hole 30 corresponding to the flange 42, and further reduce the flame length of the fire hole 30 corresponding to the flange 42 to ensure the uniformity of the flame of the fire hole 30.

[0151] In one embodiment, the arc angle A of the flange 42 on the partition plate 40 is selected from the range of (0°, 60°] to ensure the uniformity of the flame of the fire hole 30.

[0152] The arc angle A is selected from the range of (0°, 60°], that is, 0°≤A≤60°. In an example, the arc angle A can be 8°, 10°, 24°, 38°, 42°, 55°, 60° or other values ​​between 0° and 60°.

[0153] In another embodiment, the arc angle A of the flange 42 on the partition plate 40 can also be set to 360 degrees. For example, the supply amount of gas in the fire hole 30 can be changed by changing the length or inclination angle of the flange 42 in different positions of the partition plate 40, thereby ensuring that the supply amount of gas in the fire hole 30 is the same, thereby ensuring the uniformity of the flame of the fire hole 30.

[0154] In other embodiments, the arc angle A of the flange 42 can also be set to any arc angle between (0°, 360°], as long as the supply amount of gas in the fire hole 30 is the same, thereby ensuring the uniformity of the flame of the fire hole 30, and no specific limitation is made here.

[0155] In certain embodiments, the separator plate 40 is formed with a protrusion 43 configured to contact the arc generated by the ignition needle.

[0156] In this way, the partition plate 40 forms a protrusion 43, which contacts the arc generated by the ignition needle to prevent the arc from running away, thereby increasing the ignition success rate and improving the user experience.

[0157] Specifically, the protrusion 43 is arranged on the partition plate 40, which can be used to attract the arc generated by the ignition needle, so that the arc ignites the gas at the protrusion 43 to form a flame, so as to prevent the discharge arc of the ignition needle from deviating from the direction of the partition plate 40, thereby improving the ignition success rate of the burner 100.

[0158] It can be understood that the upper plate 20 and the partition plate 40 form a fire transfer gap 50 between two adjacent upper channels 21. When the arc generated by the ignition needle contacts the protrusion 43, the efficiency of the fire hole 30 in forming an overall annular flame can be improved, thereby improving the ignition success rate of the burner 100.

[0159] See also Fig.10 , an embodiment of the present invention provides a stove 1000, and the stove 1000 includes the burner 100 of the above embodiment.

[0160] In this way, the cooker 1000 is arranged with the upper hole of the upper plate and the lower hole of the lower plate facing each other, so that the fire holes of the burner are formed facing each other, thereby increasing the total area of ​​the fire holes of the burner, and further increasing the upper load limit of the burner. In addition, the fire holes 30 of the burner 100 are inclined inwardly into a cone shape, thereby ensuring the flame gathering effect of the burner 100, and further improving the flame intensity and heating efficiency of the burner 100.

[0161] Specifically, in one embodiment, the stove 1000 may be a natural gas stove, a liquefied gas stove or a coal gas stove.

[0162] It can be understood that the stove 1000 includes a burner 200, and the burner 200 includes a burner 100. The stove 1000 can be a single-burner stove, a double-burner stove, or a multi-burner stove.

[0163] like Fig.10 As shown, Fig.10 It is a schematic structural diagram of a double-burner stove, where each burner 200 includes at least one burner 100 .

[0164] In one embodiment, the burner 100 may be an inner ring burner, an outer ring burner, or a double ring burner formed by combining an inner ring burner and an outer ring burner, which is not specifically limited herein.
