Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and in particular to a burner and a stove. Background Technology

[0002] The burner in this technology includes an upper plate and a lower plate. The upper plate bulges upward to form the upper flame hole, and the lower plate is recessed downward to form the lower flame hole. The upper and lower flame holes are staggered to avoid phenomena such as flameout noise. However, this results in a relatively small flame hole area, making it difficult to obtain a large flame. Summary of the Invention

[0003] The present invention provides a burner and a stove.

[0004] This invention provides a burner comprising:

[0005] Lower board; and

[0006] An upper plate is disposed on the lower plate. The lower plate has a lower channel, and the upper plate has an upper channel corresponding to the lower channel. The lower channel and the upper channel are directly opposite each other to form the burner's flame hole. The depth direction of the flame hole forms an angle θ with the plane where the upper plate is located, and the angle θ is in the range of (0°, 90°).

[0007] In the aforementioned burner, the upper channel of the upper plate and the lower channel of the lower plate are aligned to ensure that the burner's flame holes are aligned, thereby increasing the total area of ​​the burner's flame holes and thus improving the burner's flame intensity and load limit. Furthermore, the burner's flame holes are inclined inward into a conical shape to ensure a focused flame effect, further enhancing the burner's flame intensity and heating efficiency.

[0008] In some implementations, the range of the angle θ is (0°, 60°).

[0009] This ensures the burner's flame concentration capability, thereby improving heating efficiency.

[0010] In some implementations, the angle θ is 40°.

[0011] This ensures that the flame generated by the burner is strong enough to provide better heating to the bottom of the cooking appliance.

[0012] In some embodiments, the burner includes:

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

[0014] In this way, the partition plate separates the burner orifice into a lower channel and an upper channel, effectively dividing it into two independent sub-burner orifices. The cross-sectional area of ​​each sub-burner orifice becomes smaller, thus increasing its depth. This prevents the flame from entering the gas passage through the sub-burner orifice and causing flameout noise at the moment the gas valve is closed. Furthermore, the equivalent cross-sectional area of ​​the burner orifice remains unchanged, ensuring a larger flame in the burner.

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

[0016] This connects two adjacent independent sub-flame holes together, ensuring the formation of a complete flame, thereby improving the burner's ignition transmission capability and resistance to flameout.

[0017] In some embodiments, the upper plate is annular and includes an inner ring portion and an outer ring portion, the inner ring portion protruding upward relative to the outer ring portion and spaced apart from the partition plate to form the fire transmission gap between the upper plate and the partition plate.

[0018] This allows the flame to be transmitted between the adjacent sub-flame holes on the inner ring of the upper plate and the partition plate. Furthermore, during combustion, air can reach the flame holes through the flame transmission gap, effectively replenishing the secondary air required for combustion and thus improving the burner's combustion efficiency.

[0019] In some embodiments, the outer ring, the partition plate, and the lower plate are spot-welded together at their lower parts.

[0020] This ensures stable burner hole settings, thereby providing burner stability and ultimately a stable and uniform flame.

[0021] In some embodiments, the arc of the fire-transfer gap distributed at the inner edge of the inner ring is [0°, 360°].

[0022] This creates an annular channel in the flame transfer gap, ensuring that the burner produces an overall annular flame, thereby improving flame stability.

[0023] In some embodiments, the lower plate, the partition plate, and the upper plate are integrally formed from a thin stainless steel sheet. The lower plate is recessed to form an arc-shaped lower channel, and the upper plate is convex to form an arc-shaped upper channel. The lower channel and the upper channel form a flame hole, which is elliptical in shape.

[0024] Thus, the lower plate, partition plate and upper plate are integrally formed from thin stainless steel plates, making the inner wall of the burner smoother, thereby reducing airflow resistance, effectively ensuring the supply of air required for complete combustion of gas, and 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 being substantially annular, and the partition plate further includes a flange bent from the outer peripheral edge of the partition plate body toward the lower plate.

[0026] In this way, the flange is basically circular to block the gas from entering the corresponding burner hole from the gas passage, reducing the gas output of the corresponding burner hole, and thus reducing the flame length of the corresponding burner hole to ensure the uniformity of the flame.

[0027] In some embodiments, the partition plate is formed with protrusions that are configured to contact the electric arc generated by the ignition needle.

[0028] In this way, the partition plate forms a protrusion that contacts the electric arc generated by the ignition needle to prevent the arc from running wild, thereby improving the ignition success rate and enhancing the user experience.

[0029] This invention provides a stove, which includes the burner described in the above embodiments.

[0030] In this way, the upper holes on the upper plate and the lower holes on the lower plate of the stove are aligned to ensure that the burner holes are symmetrically formed, thereby increasing the total area of ​​the burner holes and thus increasing the upper load limit of the burner. In addition, the burner holes are inclined inward into a conical shape to ensure the flame concentration effect of the burner, thereby improving the flame intensity and heating efficiency of the burner.

[0049] Please see Figures 1 to 5 An embodiment of the present invention provides a burner 100 including a lower plate 10 and an upper plate 20 disposed on the lower plate 10. The lower plate 10 has a lower channel 11, and the upper plate 20 has an upper channel 21 corresponding to the lower channel 11. The lower channel 11 and the upper channel 21 are directly opposite each other to form a flame hole 30 of the burner 100. The depth direction of the flame hole 30 forms an angle θ with the plane where the upper plate 20 is located, and the angle θ ranges from 0° to 90°.

[0050] In the aforementioned burner 100, the upper channel 21 of the upper plate 20 and the lower channel 11 of the lower plate 10 are aligned so that the flame holes 30 of the burner 100 are aligned, thereby increasing the total area of ​​the flame holes 30 of the burner 100, and thus increasing the flame intensity and load limit of the burner 100. Furthermore, the flame holes 30 of the burner 100 are inclined inward into a conical shape to ensure the flame concentration effect of the burner 100, thereby improving 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, therefore the lower plate 10 can be made of a high-temperature and corrosion-resistant material.

[0052] In one embodiment, the lower plate 10 may be made of aluminum alloy to ensure its bending performance, thereby ensuring the formation of the lower channel 11. In other embodiments, the lower plate 10 may be made of other materials, and no specific limitations are made here.

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

[0054] In one embodiment, the upper plate 20 may be made of the same material as the lower plate 10 to ensure the bending performance of the upper plate 20, thereby ensuring the formation of the upper channel 21. In other embodiments, the upper plate 20 may also be made of other materials, and no specific limitations are made here.

[0055] It is understood that the lower channel 11 and the upper channel 21 are formed opposite each other to create a ring-shaped flame hole 30. Compared with a single lower channel 11 or a single upper channel 21 that is staggered, the total area of ​​the flame hole 30 is increased, which increases the amount of gas burned, thereby improving the flame intensity of the burner 100.

[0056] In one embodiment, the angle θ formed by the depth direction of the burner hole 30 and the plane where the upper plate 20 is located is in the range of (0°, 90°), so that the burner hole 30 of the burner 100 is inclined inward into a conical shape, thereby ensuring the flame concentration effect of the burner 100 and improving the flame intensity of the burner 100 to ensure the heating rate of the bottom of the cooking appliance.

[0057] It is understandable that when the angle formed between the depth direction of the burner 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 outward, resulting in poor flame concentration and easily causing burns and flameout to the user.

[0058] In one implementation, the angle θ ranges from (0° to 90°), i.e., 0° < θ < 90°. In one example, the angle θ can be 5°, 10°, 30°, 45°, 60°, 75°, 85°, or other values ​​between 0° and 90°.

[0059] In some implementations, the angle θ ranges from 0° to 60°.

[0060] This ensures the flame concentration capability of the burner 100, thereby improving heating efficiency.

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

[0062] It is understandable that when the angle formed between 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 tilt angle of the flame of the burner 100 increases, which weakens the flame concentration effect and thus reduces the heating rate of the burner 100.

[0063] In one implementation, the angle θ ranges from (0° to 60°), i.e., 0° < θ < 60°. In one example, the angle θ can be 5°, 10°, 15°, 25°, 30°, 45°, 50°, or other values ​​between 0° and 60°.

[0064] In some implementations, the angle θ is 40°.

[0065] This ensures that the flame generated by the burner 100 is strong enough to provide better heating to the bottom of the cooking appliance.

[0066] Specifically, in one embodiment, preferably, the angle θ formed by the depth direction of the burner hole 30 and the plane where the upper plate 20 is located can be 40°. While ensuring that the burner hole 30 of the burner 100 is inclined inward into a conical shape, the flame is concentrated to cover the bottom of the cooking appliance, thereby ensuring a better heating effect at the bottom of the cooking appliance.

[0067] It is understandable that when the θ angle is 40°, the flame generated by the burner 100 can better cover the bottom of the cooking appliance to ensure the heating effect of the bottom of the cooking appliance, thereby improving the gas utilization rate and thus increasing the heating rate of the burner 100.

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

[0069] Thus, the partition plate 40 divides the flame hole 30 into a lower channel 11 and an upper channel 21, effectively dividing the flame hole 30 into two independent sub-flame holes 31. The cross-sectional area of ​​each sub-flame hole 31 becomes smaller, and therefore, the depth of the sub-flame hole 31 becomes relatively deeper. This prevents the flame from entering the gas passage through the sub-flame hole 31 and burning at the moment the gas valve is closed, thus avoiding phenomena such as flameout noise. In addition, the equivalent cross-sectional area of ​​the flame hole 30 remains unchanged, ensuring 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 divide each flame hole 30 into two sub-flame holes 31, so that the sub-flame holes 31 located on the upper and lower sides of the partition plate 40 are independent of each other.

[0071] It is understandable that the cross-sectional area of ​​the sub-flame hole 31 is relatively reduced, and the depth of the sub-flame hole 31 is relatively increased. At the moment the gas valve is closed, the path of the flame returning to the gas passage becomes relatively longer. When the flame reaches the gas passage, the flame is insufficient to reach the limit conditions for deflagration, thus effectively solving the problem of flameout noise in the burner 100.

[0072] It is worth noting that the partition plate 40 separates the flame 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 integral annular flame, which is uniform and complete, and there is no phenomenon of flame separation.

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

[0074] The partition plate 40 is disposed at the fire hole 30, therefore the partition plate 40 can be made of a high-temperature and corrosion-resistant material. In one embodiment, the partition plate 40 can be made of stainless steel. In other embodiments, the partition plate 40 can be made of aluminum alloy, copper alloy, or other materials, without specific limitations.

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

[0076] This connects two adjacent independent sub-flame holes 31 together, thereby ensuring the formation of a whole flame and improving the ignition transmission capability of the burner 100.

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

[0078] It is understood that the upper plate 20 and the partition plate 40 form a flame transmission gap 50 between two adjacent upper channels 21, so that the two adjacent upper channels 21 can be connected, thereby making the flame of the sub-flame hole 31 of the upper channel 21 stable and uniform.

[0079] That is, the flame can be transferred between the two adjacent sub-flame holes 31 of the two upper channels 21 to improve the flame transfer capability of the burner 100.

[0080] In one embodiment, the spacing d of the ignition gap 50 is selected from the range [0.50 mm, 0.80 mm], so that two adjacent independent sub-ignition holes 31 are connected together to ensure the ignition capability of the burner 100.

[0081] The spacing d of the fire-transfer gap 50 is selected from the range of 0.50 mm to 0.80 mm, i.e., 0.50 mm ≤ d ≤ 0.80 mm. In one example, d can be 0.50 mm, 0.57 mm, 0.62 mm, 0.68 mm, 0.70 mm, 0.71 mm, 0.80 mm, or other values ​​from 0.50 mm to 0.80 mm.

[0082] Please see 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 transmission gap 50 between the upper plate 20 and the partition plate 40.

[0083] This allows the flame to be transmitted between the adjacent sub-flame holes of the inner ring 22 of the upper plate 20 and the partition plate 40. In addition, during combustion, air can reach the flame hole 30 through the flame transmission gap 50, effectively replenishing 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, such that the inner ring portion 22 is spaced apart from the partition plate 40 to form a flame transfer gap 50, ensuring that flames can be transferred between two adjacent upper channels 21 in the upper plate 20.

[0085] The inner ring 22 protrudes upward relative to the outer ring 23, so that the outer ring 23 is tightly attached to the partition plate 40 to form a sealed environment and prevent the flame of the upper channel 21 from flowing back from the flame transfer gap 50 along the outer ring 23, which could cause safety hazards.

[0086] In one embodiment, multiple adjacent sub-fire holes 31 of the upper channel 21 form an integral annular flame, making the formed integral annular flame more stable and less prone to flameout, thereby improving the flameout resistance of the burner 100.

[0087] That is, the flame transfer gap 50 can connect multiple adjacent sub-flame holes 31 of the upper channel 21 at the inner ring 22, and the flame transfer gap 50 can also connect two adjacent sub-flame holes 31 of the upper channel 21 at the inner ring 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 flame transfer capability and flameout resistance of the burner 100.

[0088] In one embodiment, the lower plate 10 is fitted to the partition plate 40, and the upper plate 20 is spaced apart from the partition plate 40. In this case, adjacent lower channels 11 in the lower plate 10 are not connected, and adjacent sub-flame holes 31 in the lower channels 11 are independently configured and cannot transmit flame to each other. Adjacent upper channels 21 in the upper plate 20 are connected, meaning that adjacent sub-flame holes 31 in the upper channels 21 can transmit flame to each other, thereby improving the flame transmission capability of the burner 100.

[0089] In another embodiment, the upper plate 20 is fitted to the partition plate 40, and the lower plate 10 is spaced apart 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-flame holes 31 in the upper channel 21 are independently arranged and cannot transmit flame to each other. Two adjacent lower channels 11 in the lower plate 10 are connected, that is, two adjacent sub-flame holes 31 in the lower channel 11 can transmit flame to each other, thereby improving the flame transmission capability of the burner 100.

[0090] In other embodiments, the lower plate 10 and the partition plate 40 are spaced apart, and the upper plate 20 and the partition plate 40 are also spaced apart. The spaced arrangement of the lower plate 10 and the partition plate 40 allows communication between adjacent lower channels 11, meaning that adjacent sub-flame holes 31 of the lower channel 11 can transfer flames to each other, thereby improving the flame transfer capability of the burner 100. Furthermore, the multiple adjacent sub-flame holes 31 of the lower channel 11 form an integral annular flame, making the formed integral annular flame more stable and less prone to flameout, thus improving the burner 100's resistance to flameout. Similarly, the spaced arrangement of the upper plate 20 and the partition plate 40 allows communication between adjacent upper channels 21, meaning that adjacent sub-flame holes 31 of the two upper channels 21 can transfer flames to each other, thereby improving the flame transfer capability of the burner 100. Additionally, the multiple adjacent sub-flame holes 31 of the upper channel 21 form an integral annular flame, making the formed integral annular flame more stable and less prone to flameout, thus improving the burner 100's resistance to flameout.

[0091] Please see Figure 3 and Figure 4 In some embodiments, the outer ring 23, the partition plate 40 and the lower plate 10 are spot-welded together at their lower parts.

[0092] This ensures that the flame hole 30 is set stably, thereby providing stability to the burner 100 and thus providing a stable and uniform flame.

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

[0094] It is understandable that the outer ring 23 and the partition plate 40 can be tightly fixed by welding, so that the flame transfer gap 50 cannot pass through the outer ring 23, in order to prevent the flame of the upper channel 21 from flowing back into the gas channel from the flame transfer gap 50 along the outer ring 23, which would lead to a safety hazard.

[0095] In one embodiment, the partition plate 40 and the lower plate 10 can be tightly fixed by welding to improve the stability of the partition plate 40 and the lower plate 10.

[0096] It is understandable that the partition plate 40 and the lower plate 10 can be tightly fixed by welding, so that the lower plate 10 and the partition plate 40 do not form a fire transmission gap 50, thereby further enhancing the stability and support strength of the lower plate 10.

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

[0098] In one embodiment, the lower plate 10 and the upper plate 20 can also be connected by a screw-in process to form the burner 100. In another embodiment, the lower plate 10 and the upper plate 20 can also be connected by a pressing process to form the burner 100. In other embodiments, the lower plate 10 and the upper plate 20 can also be connected by other processes to form the burner 100, and no specific limitations are made here.

[0099] Please see 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 22 is [0°, 360°].

[0100] This creates an annular channel in the flame transfer gap 50, ensuring that the burner 100 produces an overall annular flame, thereby improving the stability of the flame.

[0101] Specifically, in one embodiment, the flame transfer gap 50 forms an annular arc channel at the inner edge of the inner ring 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 in the upper channels 21 and thus improving the flame stability of the burner 100.

[0102] It is understandable that the flame transfer gap 50 is an annular channel to improve flame stability, thereby improving the flame transfer capability and flameout resistance of the burner 100.

[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 curvature of the flame transfer gap 50, for example, if the curvature of the flame transfer gap 50 is 360°, the better the flame stability of the flame hole 30, thereby making the burner 100 have stronger flame transfer capability and anti-flame-out capability.

[0105] In some embodiments, the lower plate 10, the partition plate 40 and the upper plate 20 are integrally formed from a thin stainless steel sheet. The lower plate 10 is recessed 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 flame hole 30, which is elliptical in shape.

[0106] Thus, the lower plate 10, the partition plate 40 and the upper plate 20 are integrally formed from thin stainless steel plates, which makes the inner wall of the burner 100 relatively smooth, thereby reducing airflow resistance and effectively ensuring the supply of air required for complete combustion of gas. In addition, the burner 100 has a simple structure and low cost.

[0107] Specifically, in one embodiment, the lower plate 10 can be used to form the flame hole 30, therefore the lower plate 10 can be made of a high-temperature and corrosion-resistant material. That is, the lower plate 10 can be integrally formed from stainless steel to shorten production time and save production costs. In other embodiments, the lower plate 10 can be integrally formed from aluminum alloy, or from other metal or alloy materials, without specific limitations.

[0108] In one embodiment, the partition plate 40 can be used to separate the fire holes 30, therefore the partition plate 40 can be made of a high-temperature and corrosion-resistant material. That is, the partition plate 40 can be integrally formed from stainless steel to shorten production time and save production costs. In other embodiments, the partition plate 40 can be integrally formed from aluminum alloy, or other metal or alloy materials, without specific limitations.

[0109] Similarly, the upper plate 20 can be used to form the fire hole 30 with the lower plate 10, therefore the upper plate 20 can be made of a high-temperature and corrosion-resistant material. That is, the upper plate 20 can be integrally formed from stainless steel to shorten production time and save production costs. In other embodiments, the upper plate 20 can be integrally formed from aluminum alloy, or from other metal or alloy materials, without specific limitations.

[0110] In one embodiment, the lower plate 10, the partition plate 40, and the upper plate 20 can be integrally formed from stainless steel to create the burner 100. This results in a thinner burner 100 with a smooth inner wall, ensuring smooth flow of the gas-air mixture and improving the burner 100's operating efficiency. Furthermore, the integral forming of the lower plate 10, partition plate 40, and upper plate 20 with stainless steel ensures uniform thickness of the lower plate 10 and upper plate 20, guaranteeing uniform heating and improving the flame uniformity of the lower channel 11 and upper channel 21.

[0111] In one implementation, please refer to Figure 1 The lower channel 11 is concave in an arc shape to ensure that the lower channel 11 has a suitable internal cavity space, thereby ensuring the safe and rapid delivery of gas.

[0112] Similarly, the upper channel 21 is arc-shaped and convex to ensure that the upper channel 21 has a suitable internal cavity space, thereby ensuring the safe and rapid delivery of gas.

[0113] It is understandable that the lower channel 11 and the upper channel 21 are aligned to form an elliptical flame hole 30, so as to ensure that the cross-sectional area of ​​the flame hole 30 is large, and at the same time, the amount of gas delivered by the flame hole 30 is large, thereby ensuring a large flame intensity, and thus improving flame uniformity and heating efficiency.

[0114] In some embodiments, the lower plate 10 and the upper plate 20 are substantially annular, with multiple lower channels 11 distributed along the inner circumference of the lower plate 10, and multiple upper channels 21 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 of the lower channel 11 and the upper channel 21 is concentrated, while the flame's coverage of the pot bottom is strengthened, the convective heat transfer coefficient is improved, the combustion efficiency is increased, the amount of gas used is saved, and it is environmentally friendly.

[0116] Specifically, in one embodiment, a plurality of lower channels 11 are distributed along the inner circumference of the lower plate 10 and arranged in a ring 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] Multiple upper channels 21 are distributed along the inner circumference of the upper plate 20 and arranged in a ring shape below the upper plate 20, so that the flames of the sub-fire holes 31 of the multiple upper channels 21 are dense and vigorous.

[0118] In other words, the multiple lower channels 11 and multiple upper channels 21 cooperate to form multiple flame holes 30, ensuring that the multiple flame holes 30 are distributed in a ring shape, which makes the flame of the flame holes 30 converge and improves combustion efficiency. In addition, the ring distribution of multiple flame holes 30 strengthens the flame's coverage of the pot bottom, increases the convective heat transfer coefficient between the flame and the pot bottom, and thus saves gas consumption.

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

[0120] In this way, the flame of the fire hole 30 formed by the cooperation of the lower channel 11 and the upper channel 21 is concentrated, making the flame more vigorous and improving the combustion efficiency of the gas.

[0121] Specifically, such as 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 angle E, and the corresponding radial direction of one of the lower plates 10 is the dashed line direction of angle E.

[0122] The depth direction of the lower channel 11 is inclined relative to the radial direction of the lower plate 10, which causes the flame of the sub-flame hole 31 of the lower channel 11 to converge towards the inner circumference of the lower plate 10, making the flame more vigorous and improving the combustion efficiency of the 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. The depth direction of one of the upper channels 21 is the solid line direction of angle F, and the radial direction of one of the upper plates 20 is the dashed line direction of angle F.

[0124] The depth direction of the upper channel 21 is inclined relative to the radial direction of the upper plate 20, which causes the flame of the sub-flame hole 31 of the upper channel 21 to converge towards the inner circumference of the upper plate 20, making the flame more vigorous and improving the combustion efficiency of the gas.

[0125] In summary, the flame concentration in the fire hole 30 formed by the cooperation of the lower channel 11 and the upper channel 21 results in a more vigorous flame, thereby improving the combustion efficiency of the gas.

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

[0127] Thus, the inner ring 12 and the inner ring 22 of the lower plate are arranged in the same direction to ensure that they cooperate to form multiple fire holes 30 that face upwards and have the same orientation as the lower channel 11 and the upper channel 21, so that the flame of the fire hole 30 is closer to the bottom of the pot and the heat transfer efficiency between the flame and the bottom of the pot is improved.

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

[0129] like Figure 6 and Figure 7 As shown, the inner ring 22 is arranged in a circular shape, and the inner ring 22 arches radially from the outside to the inside away from the lower plate 10, so as to cooperate with the inner ring 12 of the lower plate to form a plurality of fire holes 30 distributed in a circular shape, so that 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.

[0130] Please see Figure 6 and Figure 7 In some embodiments, the lower plate 10 includes a lower ejector tube portion 13 connected to the inner ring portion 12 of the lower plate. The lower ejector tube portion 13 forms a lower ejector conduit 131. The lower plate 10 forms a lower air passage 71 that connects the lower ejector conduit 131 and 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 forms an upper ejector conduit 241. The upper plate 20 forms an upper air passage 72 that connects the upper ejector conduit 241 and the upper channel 21. The lower ejector tube portion 13 and the upper ejector tube portion 24 cooperate to form the ejector tube 60 of the burner 100. The lower air passage 71 and the upper air passage 72 cooperate to form the air passage 70 of the burner 100. The ejector tube 60 and the air passage 70 are connected to form the ejector tube outlet 61. The diameter of the flame hole 30 away from the ejector tube outlet 61 is larger than the diameter of the flame hole 30 near the ejector tube outlet 61.

[0131] Thus, the aperture size of the flame hole 30 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 generated by the gas flowing through the flame hole 30 far from the ejector tube outlet 61 is also larger, thereby ensuring that the flame of the flame hole 30 of the burner 100 is uniform.

[0132] Specifically, in one embodiment, the ejector tube 60 is connected to the air passage 70, and the ejector tube 60 is used to mix the gas mixture of fuel gas and air evenly and deliver it to the air passage 70.

[0133] The gas passage 70 is connected to the flame port 30. The gas passage 70 can remix the gas mixture of gas and air to produce a uniform flame through the flame port 30.

[0134] like Figure 6 As shown, in one embodiment, the aperture of the flame hole 30 near the ejector tube outlet 61 is smaller, and the aperture of the flame hole 30 far from the ejector tube outlet 61 is larger. The aperture of the flame hole 30 gradually increases from the position near the ejector tube outlet 61 to the position far from the ejector tube outlet 61, and the aperture of the flame hole 30 reaches its maximum at point M.

[0135] That is, the diameter of the flame hole 30 gradually increases from the position near the ejector tube outlet 61 to the position far away from the ejector tube outlet 61, so as to ensure that the flame generated by the gas flowing through the flame hole 30 at point M is also larger, thereby ensuring that the flame length generated by multiple flame holes 30 is equal, and thus ensuring that the flame of the flame hole 30 of the burner 100 is uniform.

[0136] Please see Figure 6 In some embodiments, the centerline L of the ejector tube 60 passes through the center O of the central circle R of the airway 70.

[0137] This allows the gas to flow evenly along the annular gas passage 70 after entering the gas passage 70 from the injector tube 60, which helps to improve the ignition success rate of the protrusion 43.

[0138] Specifically, in one implementation, such as Figure 6 As shown, the gas passage 70 is arranged in a ring shape, and the center line L of the ejector tube 60 passes through the center O of the central circle R of the gas passage 70. This allows the gas mixture of combustion gas and air to flow evenly to both sides of the gas passage 70 after entering the gas passage 70 from the ejector tube 60, ensuring that the gas mixture of combustion gas and air is evenly distributed in the gas passage 70. This facilitates the ignition of the gas mixture of combustion gas and air by the discharge arc, thereby producing a ring-shaped flame and improving the ignition success rate of the protrusion 43.

[0139] Please see Figure 8 and Figure 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. The partition plate body 41 is basically annular. The partition plate 40 also includes a flange 42 that is 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 provided corresponding to the ejector outlet 61 to block the gas from entering the flame hole 30 corresponding to the flange 42 through the gas passage 70 from the ejector outlet 61.

[0140] Thus, with all the gas passages 70 having the same cross-sectional area and all the flame holes 30 having the same size, the flange 42 is basically arc-shaped and is set to correspond to the ejector tube outlet 61 to block the gas from entering the flame 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 flame hole 30 corresponding to the flange 42 and thus reducing the flame length of the flame hole 30 corresponding to the flange 42, so as to ensure the uniformity of the flame of the flame hole 30.

[0141] Specifically, in one embodiment, the pressure of the gas-air mixture near the ejector outlet 61 is higher and the flow rate is faster. When all the cross-sectional areas of the gas passages 70 are the same and all the flame holes 30 are the same size, the flame produced by the flame hole 30 near the ejector outlet 61 is longer.

[0142] Similarly, such as Figure 9 As shown, the pressure of the gas-air mixture is lower and the flow rate is slower at the location far from the ejector outlet 61 (such as point M). When the cross-sectional area of ​​all gas passages 70 is the same and the size of all flame holes 30 is the same, the flame produced by the flame hole 30 near the ejector outlet 61 is shorter.

[0143] In summary, the embodiments of the present invention can reduce the gas output of the flame holes 30 corresponding to the flange 42 by setting an arc-shaped flange 42 on the partition plate 40 to block the gas from entering the flame hole 30 corresponding to the flange 42 through the gas passage 70 from the injector outlet 61, thereby ensuring the uniformity of the flame of all flame 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 flame holes 30, so as to ensure that the flame length of all flame holes 30 is the same, thereby ensuring the uniformity of the flame of the flame holes 30.

[0145] In another embodiment, the flange 42 can also be bent toward the upper plate 20 to block the flow of gas in different flame holes 30, so as to ensure that the flame length of all flame holes 30 is the same, thereby ensuring the uniformity of the flame of the flame holes 30.

[0146] In other embodiments, the flange 42 can be bent in both the direction of the lower plate 10 and the direction of the upper plate 20 to ensure that the flame length of all the flame holes 30 is the same, thereby ensuring the uniformity of the flame of the flame holes 30.

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

[0148] Thus, by setting 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. It can be used to block the gas from entering the corresponding flame hole 30 of the flange 42 through the gas passage 70 from the injector outlet 61. That is, the flange 42 can be made of a high-temperature 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 aluminum alloy, copper alloy, or other materials, without specific limitations.

[0150] Preferably, in one embodiment, such as Figure 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 flame hole 30 corresponding to the flange 42 through the gas passage 70 from the injector outlet 61, thereby reducing the gas output of the flame hole 30 corresponding to the flange 42 and thus reducing the flame length of the flame hole 30 corresponding to the flange 42, so as to ensure the uniformity of the flame of the flame 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 in the fire hole 30.

[0152] The arc angle A is selected from the range (0°, 60°], i.e., 0°≤A≤60°. In one 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 of gas in the flame hole 30 can be changed by changing the length or tilt angle of the flange 42 in different positions of the partition plate 40, so as to ensure that the supply of gas in the flame hole 30 is the same, thereby ensuring the uniformity of the flame in the flame 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 gas supply in the flame hole 30 is the same, thereby ensuring the uniformity of the flame in the flame hole 30. No specific restrictions are imposed here.

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

[0156] Thus, the partition plate 40 forms a protrusion 43 that contacts the electric arc generated by the ignition needle to prevent the electric arc from running wild, thereby improving the ignition success rate and enhancing the user experience.

[0157] Specifically, the protrusion 43 is provided on the partition plate 40 and can be used to attract the electric arc generated by the ignition needle, so that the electric 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 is understood that the upper plate 20 and the partition plate 40 form a flame transfer gap 50 between two adjacent upper channels 21. When the electric arc generated by the ignition needle contacts the protrusion 43, the efficiency of the flame hole 30 in forming an overall annular flame can be improved, thereby increasing the ignition success rate of the burner 100.

[0159] Please see Figure 10 The present invention provides a stove 1000, which includes the burner 100 of the above embodiment.

[0160] Thus, the upper holes of the upper plate and the lower holes of the lower plate of the stove 1000 are aligned to ensure that the burner holes are symmetrically formed, thereby increasing the total area of ​​the burner holes and thus increasing the upper load limit of the burner. In addition, the burner holes 30 of the burner 100 are inclined inward into a conical shape to ensure the flame concentration effect of the burner 100, thereby improving the flame intensity and heating efficiency of the burner 100.

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

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

[0163] like Figure 10 As shown, Figure 10 This is a schematic diagram of a dual-burner stove, where each burner 200 includes at least one burner 100.

[0164] In one embodiment, the burner 100 can be an inner ring burner, an outer ring burner, or a dual-ring burner formed by combining an inner ring burner and an outer ring burner; no specific limitation is made here.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
