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] In the related art, a burner generally has a circle of fire holes, which are arranged at intervals. However, an ignition needle is generally arranged only near one or two of the fire holes. When igniting, the ignition needle ignites the flame of one or two adjacent fire holes, and then ignites the adjacent fire holes through the flame, thereby achieving combustion of the entire circle of fire holes. However, due to the interval arrangement of the fire holes, the flame transfer ability is poor, and secondly, the phenomenon of flame failure may occur. 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] A lower plate, wherein the lower plate is formed with a lower channel;

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

[0007] A partition plate is arranged between the lower plate and the upper plate and separates the lower hole channel from the upper hole channel, and a fire transfer gap is formed between the upper plate and the partition plate.

[0008] The burner forms a flame transfer gap between two adjacent independent upper channels, so that the flame between the upper plate and the partition plate is highly connectable to form a ring flame, thereby improving the burner's flame transfer ability and flame-out resistance during the ignition process, ensuring that the flame is not easily flamed out and extinguished.

[0009] In some embodiments, the upper plate is annular and includes an upper plate upper section and an upper plate lower section, the upper plate upper section protrudes upward relative to the upper plate lower section and is spaced apart from the partition plate to form the fire transfer gap; or

[0010] The lower plate is annular and includes an upper lower plate portion and a lower lower plate portion. The upper lower plate portion is recessed downward relative to the lower lower plate portion and is spaced apart from the partition plate to form the fire transfer gap.

[0011] In this way, the adjacent fire holes between the upper plate section and the partition plate can transfer flames, or the adjacent fire holes between the upper plate section and 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.

[0012] In some embodiments, the setting range of the fire transfer gap in the circumferential direction is [0°, 360°].

[0013] 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.

[0014] In some embodiments, the lower section of the upper plate, the partition plate and the lower plate are tightly fixed by spot welding at the lower part; or

[0015] The lower section of the lower plate, the partition plate and the upper plate are tightly fixed by spot welding at the lower parts.

[0016] This improves the stability of the burner and provides a stable and uniform flame.

[0017] In some embodiments, the ratio of the radial length of the upper plate upper portion to the total length of the upper plate upper portion and the upper plate lower portion is in the range of Wherein, a1 is the radial length of the upper section of the upper plate, and b1 is the radial length of the lower section of the upper plate; or

[0018] The ratio of the radial length of the upper portion of the lower plate to the total length of the upper portion of the lower plate and the lower portion of the lower plate is in the range of Among them, a2 is the radial length of the upper section of the lower plate, and b2 is the radial length of the lower section of the lower plate.

[0019] In this way, it is ensured that the fire transfer gap has an appropriate radial length, thereby improving the fire transfer and flame stabilization effect. When the ratio of the radial length of the upper section of the upper plate to the total length of the upper section and the lower section of the upper plate is less than 0.3, the radial length of the upper section of the upper plate is too small, which makes the radial length of the fire transfer gap too small, and the fire transfer and flame stabilization ability is insufficient, which is prone to flameout. When the ratio of the radial length of the upper section of the upper plate to the total length of the upper section and the lower section of the upper plate is greater than 0.8, the radial length of the upper section of the upper plate is too large, which makes the radial length of the fire transfer gap too large, making it very easy for the flame to flow back into the airway and cause a deflagration sound, thereby creating a safety hazard.

[0020] In some embodiments, the ratio of the radial length of the upper plate upper portion to the total length of the upper plate upper portion and the upper plate lower portion is in the range of Wherein, a1 is the radial length of the upper section of the upper plate, and b1 is the radial length of the lower section of the upper plate; or

[0021] The ratio of the radial length of the upper portion of the lower plate to the total length of the upper portion of the lower plate and the lower portion of the lower plate is in the range of Among them, a2 is the radial length of the upper section of the lower plate, and b2 is the radial length of the lower section of the lower plate.

[0022] In this way, a more suitable radial length of the fire transfer gap is preferably selected, so that the fire transfer and flame stabilization effect of the fire transfer gap is better. When the ratio of the radial length of the upper section of the upper plate to the total length of the upper section and the lower section of the upper plate is less than 0.45, the radial length of the upper section of the upper plate is small, which makes the radial length of the fire transfer gap small, and the fire transfer and flame stabilization ability is poor, which is easy to cause flameout. When the ratio of the radial length of the upper section of the upper plate to the total length of the upper section and the lower section of the upper plate is greater than 0.55, the radial length of the upper section of the upper plate is large, which makes the radial length of the fire transfer gap large, making it easier for the flame to flow back into the airway to cause a deflagration sound, thereby creating a safety hazard.

[0023] In some embodiments, the gap between the upper plate portion and the partition plate is in the range of (0, 3 mm); or

[0024] The gap between the upper portion of the lower plate and the partition plate is in the range of (0, 3 mm).

[0025] In this way, it is ensured that the fire transfer gap can achieve normal fire transfer and flame stabilization functions, thereby ensuring the normal operation of the burner.

[0026] In some embodiments, the gap between the upper plate portion and the partition plate is in the range of (1 mm, 2 mm); or

[0027] The gap between the upper portion of the lower plate and the partition plate is in the range of (1 mm, 2 mm).

[0028] In this way, it is ensured that a suitable gap is formed between the upper section of the upper plate and the partition plate, thereby improving the fire transfer and flame stabilization effect of the fire transfer gap.

[0029] In some embodiments, the lower plate, the partition plate and the upper plate are integrally formed of stainless steel sheets.

[0030] 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.

[0031] In certain embodiments, the thicknesses of the lower plate, the separator plate, and the upper plate are substantially the same.

[0032] In this way, the wall thickness of the burner is ensured to be uniform, so that the burner is heated evenly and has better stability.

[0033] In certain embodiments, the thickness of the lower plate, the partition plate, and the upper plate is in the range of (0.5 mm, 2 mm).

[0034] In this way, the burner can be guaranteed to work normally and provide uniform flame. When the thickness is less than 0.5mm, the thickness of the lower plate, the partition plate and the upper plate is too thin, and it is easy to be overheated and cause deformation and fire leakage, which will cause safety hazards. When the thickness is greater than 2mm, the thickness of the lower plate, the partition plate and the upper plate is too thick, the weight is large, and the production cost is high.

[0035] In certain embodiments, the thickness of the lower plate, the partition plate, and the upper plate is in the range of (0.8 mm, 1.5 mm).

[0036] In this way, a burner with suitable thickness is formed, thereby improving flame uniformity. When the thickness is less than 0.8 mm, the thickness of the lower plate, the partition plate and the upper plate is relatively thin, and it is easy to be deformed and leak fire due to high heat, which creates safety hazards. When the thickness is greater than 1.5 mm, the thickness of the lower plate, the partition plate and the upper plate is relatively thick, the weight is large, and the production cost is high.

[0037] In some embodiments, the lower plate is concave to form a lower channel, and the upper plate is convex to form an upper channel; and

[0038] The lower hole channel and the upper hole channel are directly opposite to form a fire hole of the burner.

[0039] In this way, the fire holes of the burner are formed in a right-angled manner, thereby increasing the total area of ​​the fire holes of the burner, and further increasing the flame intensity and load upper limit of the burner.

[0040] In some embodiments, the depth direction of the fire hole forms an angle θ with the plane where the upper plate is located, and the range of the angle θ is (0°, 90°).

[0041] In this way, the fire hole of the burner is inclined inwardly into a cone shape, thereby ensuring the flame gathering effect of the burner, thereby improving the flame intensity and heating efficiency of the burner.

[0042] In certain embodiments, the angle θ is in the range of (0°, 60°).

[0043] In this way, the flame focusing ability of the burner is ensured, thereby improving the heating efficiency.

[0044] In certain embodiments, the angle θ is 40°.

[0045] 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.

[0046] An embodiment of the present invention provides a stove, which includes the burner described in the above embodiment.

[0047] In this way, the stove forms a fire transfer gap between two adjacent independent upper channels, so that the flame between the upper plate and the partition plate is highly connectable to form a ring flame, thereby improving the burner's flame transfer ability and anti-fire ability during the ignition process, ensuring that the flame is not easily flamed out.

In order to simplify the disclosure of the present invention, the components and settings of specific examples are described herein. Of course, they are merely examples, and the purpose is not to limit the present invention.

[0064] See also Figures 1 to 5 A burner 100 provided in an embodiment of the present invention includes a lower plate 10, an upper plate 20 disposed on the lower plate 10, and a partition plate 30. The lower plate 10 is formed with a lower channel 11, and the upper plate 20 is formed with an upper channel 21. The partition plate 30 is disposed between the lower plate 10 and the upper plate 20, and separates the lower channel 11 from the upper channel 21, and a flame transfer gap 40 is formed between the upper plate 20 and the partition plate 30.

[0065] The burner 100 forms a flame transfer gap 40 between two adjacent independent upper channels 21, so that the flame between the upper plate 20 and the partition plate 30 is highly connectable to form a ring flame, thereby improving the flame transfer capability and flame-out resistance of the burner 100 during the ignition process, and ensuring that the flame is not easily deflated and extinguished.

[0066] Specifically, in one embodiment, the partition plate 30 is disposed between the lower plate 10 and the upper plate 20, and is used to separate the plurality of lower channels 11 and the plurality of upper channels 21 into a plurality of sub-fire holes 51, respectively, so that the sub-fire holes 51 located on the upper and lower sides of the partition plate 30 are independent of each other, that is, the cross-sectional area of ​​each sub-fire hole 51 is relatively reduced, and the depth of the sub-fire hole 51 is relatively deepened. At the moment when the gas valve is closed, the path of the flame return gas channel becomes relatively longer. When the flame reaches the gas channel, the flame is not enough to reach the limit condition of deflagration, so the problem of flameout noise of the burner 100 can be effectively solved.

[0067] In one embodiment, the partition plate 30 may be formed with a sharp-shaped protrusion 31 (eg Figure 6 As shown), the discharge arc is attracted to ignite the gas at the outlets of the lower channel 11 and the upper channel 21 to prevent the arc from running away, thereby improving the ignition efficiency of the burner 100.

[0068] The partition plate 30 is disposed between the lower hole channel 11 and the upper hole channel 21 , so the partition plate 30 may be made of a high temperature resistant and corrosion resistant material.

[0069] In one embodiment, the material of the partition plate 30 may be a stainless steel partition plate. In other embodiments, the material of the partition plate 30 may be an aluminum alloy partition plate, a copper alloy partition plate, or a partition plate of other materials, which is not specifically limited here.

[0070] In one embodiment, the flame transfer gap 40 is formed between the upper plate 20 and the partition plate 30 to ensure that a connectable gap is formed between two adjacent upper channels 21 in the upper plate 20 to play a role in transferring and stabilizing the flame.

[0071] It can be understood that during the ignition process of the burner 100, the discharge arc can ignite the gas at the outlet of one of the upper channels 21 through an ignition needle (not shown), and transfer the flame to two adjacent upper channels 21 through the flame transfer gap 40, thereby forming a continuous flame, thereby ensuring the flame transfer efficiency and ignition success rate.

[0072] During the continuous operation of the burner 100, the fire transfer gap 40 connects the two adjacent upper channels 21 and continuously replenishes secondary air to ensure that the gas in the two adjacent upper channels 21 is fully burned, so that the burner 100 forms an overall continuous flame, thereby ensuring high flame intensity and good stability, thereby improving the burner 100's anti-fire ability and achieving the purpose of flame stabilization.

[0073] In one embodiment, the range of the flame transfer gap 40 may be [0.50 mm, 0.80 mm], so that two adjacent independent upper channels 21 are connected together to ensure the flame transfer capability and flame stabilization capability of the burner 100 .

[0074] That is, the range of the spark gap 40 is 0.50 mm to 0.80 mm, that is, 0.50 mm≤d≤0.80 mm. In some examples, the spark gap 40 can be 0.50 mm, 0.57 mm, 0.62 mm, 0.68 mm, 0.70 mm, 0.71 mm, 0.80 mm or other values ​​between 0.50 mm and 0.80 mm.

[0075] When the flame transfer gap 40 is less than 0.50 mm, the flame transfer gap 40 is too small, and the flame transfer efficiency and the secondary air supplement efficiency are low, so that the flame transfer ability of the burner 100 is poor.

[0076] When the flame transfer gap 40 is larger than 0.80 mm, the flame transfer gap 40 is too large, the flame stability is low, and the burner 100 has poor flameout resistance, which easily leads to flameout and extinguishing.

[0077] In one embodiment, the lower plate 10 is tightly fixed to the partition plate 30 to improve the stability and support strength of the partition plate 30 and the upper plate 20 , thereby improving the stability and safety of the burner 100 .

[0078] In other embodiments, the fire transfer gap 40 may also be separately provided between the lower plate 10 and the partition plate 30, or may be provided simultaneously between the upper plate 20 and the partition plate 30 and between the lower plate 10 and the partition plate 30, without any specific limitation.

[0079] See also Figures 4 to 6 In some embodiments, the upper plate 20 is annular and includes an upper plate upper section 22 and an upper plate lower section 23. The upper plate upper section 22 protrudes upward relative to the upper plate lower section 23 and is spaced apart from the partition plate 30 to form a fire transfer gap 40; or

[0080] The lower plate 10 is annular and includes a lower plate upper portion 12 and a lower plate lower portion 13 (such as Figure 8 The lower plate upper section 12 is recessed downward relative to the lower plate lower section 13 (not shown), and is spaced apart from the partition plate 30 to form a fire transfer gap 40.

[0081] In this way, the adjacent fire holes 50 between the upper plate section 22 and the partition plate 30 can transfer flames, or the adjacent fire holes between the lower plate section 12 and the partition plate 30 can transfer flames. In addition, during the combustion process, air can reach the fire holes 50 through the flame transfer gap, effectively supplementing the secondary air required for combustion, thereby improving the combustion efficiency of the burner 100.

[0082] Specifically, Figure 4 and Figure 5 As shown, in one embodiment, the upper section 22 of the upper plate protrudes upward relative to the lower section 23 of the upper plate, so that the upper section 22 of the upper plate is spaced apart from the partition plate 30 to form a fire transfer gap 40 to ensure that flames can be transferred between two adjacent upper channels 21 in the upper plate 20.

[0083] The upper section 22 of the upper plate protrudes upward relative to the lower section 23 of the upper plate, so that the lower section 23 of the upper plate is closely arranged with the partition plate 30 to form a closed environment to prevent the flame of the upper channel 21 from flowing back from the fire transfer gap 40 along the lower section 23 of the upper plate to cause safety hazards.

[0084] In one embodiment, a plurality of adjacent sub-fire holes 51 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 .

[0085] That is, the fire transfer gap 40 can connect together a plurality of adjacent sub-fire holes 51 of the upper channel 21 at the upper plate upper section 22, and the fire transfer gap 40 can also connect together two adjacent sub-fire holes 51 of the upper channel 21 at the upper plate upper section 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 30, thereby improving the fire transfer capability and anti-fire capability of the burner 100.

[0086] Similarly, in another embodiment, the upper section 12 of the lower plate is recessed downward relative to the lower section 13 of the lower plate (not shown), so that the upper section 12 of the lower plate is spaced apart from the partition plate 30 to form a fire transfer gap 40, ensuring that the flames of two adjacent lower channels 11 in the lower plate 10 can be transferred to each other, thereby ensuring that a complete flame is formed between the lower plate 10 and the partition plate 30. To avoid redundancy, it will not be repeated here.

[0087] In some embodiments, the setting range of the fire transfer gap 40 in the circumferential direction is [0°, 360°].

[0088] In this way, the flame transfer gap 40 forms an annular channel, thereby ensuring that the burner 100 generates an overall annular flame, thereby improving the stability of the flame.

[0089] Specifically, in one embodiment, the fire transfer gap 40 forms a channel with an annular arc on the inner edge of the upper plate section 22 to ensure that the flames of multiple adjacent upper channels 21 are in an overall ring shape, thereby improving the stability of the flames of the upper channels 21 and further improving the flame stability of the burner 100.

[0090] It can be understood that the flame transfer gap 40 is an annular channel to improve flame stability, thereby improving the flame transfer capability and flameout resistance of the burner 100 .

[0091] In one embodiment, the arc of the fire transfer gap 40 distributed on the inner edge of the upper plate upper section 22 is [0°, 360°]. For example, in some examples, the arc of the fire transfer gap 40 can be 0°, 90°, 180°, 270°, 360° or other angles between 0° and 360°.

[0092] It can be understood that the larger the arc of the fire transfer gap 40, for example, the arc of the fire transfer gap 40 is 360°, the better the flame stability of the fire hole 50, thereby making the burner 100 have stronger fire transfer ability and anti-fire ability.

[0093] It is worth noting that the partition plate 30 separates the fire hole 50 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.

[0094] That is, the partition plate 30 is disposed between the lower plate 10 and the upper plate 20 , and does not affect the flame size of the fire hole 50 , thereby ensuring that the burner 100 maintains a relatively large flame intensity.

[0095] See also Figure 4 In some embodiments, the lower portion of the upper plate lower section 23, the partition plate 30 and the lower plate 10 are tightly fixed by spot welding; or

[0096] The lower section 13 of the lower plate, the partition plate 30 and the upper plate 20 are tightly fixed at the bottom by spot welding.

[0097] In this way, the flame holes 50 are stably arranged, thereby providing stability for the burner 100 and further providing a stable and uniform flame.

[0098] Specifically, Figure 4 As shown, in one embodiment, the upper plate lower section 23 and the partition plate 30 can be tightly fixed by a welding process to improve the stability of the upper plate lower section 23 and the partition plate 30.

[0099] It can be understood that the upper plate lower section 23 and the partition plate 30 can be tightly fixed by welding process, so that the fire transfer gap 40 cannot pass through the upper plate lower section 23, so as to avoid the flame of the upper channel 21 from the fire transfer gap 40 along the upper plate lower section 23 to flow back to the airway, causing safety hazards.

[0100] In one embodiment, the partition plate 30 and the lower plate 10 may be closely fixed by a welding process to improve the stability of the partition plate 30 and the lower plate 10 .

[0101] It can be understood that the partition plate 30 and the lower plate 10 can be tightly fixed by a welding process, so that no fire transfer gap 40 is formed between the lower plate 10 and the partition plate 30, thereby enhancing the stability and supporting strength of the lower plate 10.

[0102] In summary, the upper plate lower section 23, the partition plate 30 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.

[0103] Similarly, in another embodiment, the lower section 13 of the lower plate and the partition plate 30 can be tightly fixed by welding technology (not shown) to improve the stability of the lower section 13 of the lower plate and the partition plate 30, while ensuring that the upper section 12 of the lower plate and the partition plate 30 form a fire transfer gap 40. At this time, the upper plate 20 may not form a fire transfer gap 40 with the partition plate 30. To avoid redundancy, it will not be repeated here.

[0104] 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.

[0105] See also Figure 4 In some embodiments, the ratio of the radial length of the upper plate upper section 22 to the total length of the upper plate upper section 22 and the upper plate lower section 23 is in the range of Wherein, a1 is the radial length of the upper section of the upper plate, and b1 is the radial length of the lower section of the upper plate; or

[0106] The ratio of the radial length of the lower plate upper section 12 to the total length of the lower plate upper section 12 and the lower plate lower section 13 is in the range of Among them, a2 is the radial length of the upper section of the lower plate, and b2 is the radial length of the lower section of the lower plate (not shown in the figure).

[0107] In this way, it is ensured that the fire transfer gap 40 has an appropriate radial length, thereby improving the fire transfer and flame stabilization effect.

[0108] Specifically, Figure 4 As shown, in one embodiment, a suitable ratio should be selected between the radial length a1 of the upper plate upper section 22 and the total length (a1+b1) of the upper plate upper section 22 and the upper plate lower section 23 to improve the flame transfer and stabilization effect.

[0109] In one embodiment, The ratio range of can be (0.3, 0.8). In some examples, The ratio can be 0.35, 0.38, 0.4, 0.45, 0.5, 0.7, 0.75 or other values ​​between 0.3 and 0.8.

[0110] When the ratio of the radial length of the upper plate upper section 22 to the total length of the upper plate upper section 22 and the upper plate lower section 23 is less than 0.3, the radial length of the upper plate upper section 22 is too small, so that the radial length of the fire transfer gap 40 is too small, the fire transfer and flame stabilization capabilities are insufficient, and flameout is likely to occur.

[0111] When the ratio of the radial length of the upper plate upper section 22 to the total length of the upper plate upper section 22 and the upper plate lower section 23 is greater than 0.8, the radial length of the upper plate upper section 22 is too large, which makes the radial length of the fire transfer gap 40 too large, making it very easy for the flame to flow back into the airway and cause a deflagration sound, thereby creating a safety hazard.

[0112] Similarly, in another embodiment, a suitable ratio (not shown) should be selected between the radial length a2 of the lower plate upper section 12 and the total length (a2+b2) of the lower plate upper section 12 and the lower plate lower section 13 to improve the flame transfer and stabilization effect.

[0113] In one embodiment, The ratio range of can be (0.3, 0.8). In some examples, The ratio can be 0.35, 0.38, 0.4, 0.45, 0.5, 0.7, 0.75 or other values ​​between 0.3 and 0.8.

[0114] When the ratio of the radial length of the lower plate upper section 12 to the total length of the lower plate upper section 12 and the lower plate lower section 13 is less than 0.3, the radial length of the lower plate upper section 12 is too small, so that the radial length of the fire transfer gap 40 is too small, the fire transfer and flame stabilization capabilities are insufficient, and flameout is likely to occur.

[0115] When the ratio of the radial length of the lower plate upper section 12 to the total length of the lower plate upper section 12 and the lower plate lower section 13 is greater than 0.8, the radial length of the lower plate upper section 12 is too large, so that the radial length of the fire transfer gap 40 is too large, and the flame is very easy to flow back into the airway to cause a deflagration sound, thereby creating a safety hazard.

[0116] In some embodiments, the ratio of the radial length of the upper plate upper section 22 to the total length of the upper plate upper section 22 and the upper plate lower section 23 is in the range of Wherein, a1 is the radial length of the upper section of the upper plate, and b1 is the radial length of the lower section of the upper plate; or

[0117] The ratio of the radial length of the lower plate upper section 12 to the total length of the lower plate upper section 12 and the lower plate lower section 13 is in the range of Among them, a2 is the radial length of the upper part of the lower plate, and b2 is the radial length of the lower part of the lower plate.

[0118] In this way, a more suitable radial length of the fire transfer gap 40 is preferably selected, so that the fire transfer and flame stabilization effects of the fire transfer gap 40 are better.

[0119] Specifically, Figure 4 As shown, preferably, the ratio of the radial length a1 of the upper plate upper section 22 to the total length (a1+b1) of the upper plate upper section 22 and the upper plate lower section 23 can be in the range of (0.45, 0.55) so that the fire transfer gap 40 has a better fire transfer and flame stabilization effect.

[0120] In some examples, The ratio can be 0.46, 0.48, 0.49, 0.50, 0.52, 0.53, 0.54 or other values ​​between 0.45 and 0.55.

[0121] When the ratio of the radial length of the upper plate upper section 22 to the total length of the upper plate upper section 22 and the upper plate lower section 23 is less than 0.45, the radial length of the upper plate upper section 22 is small, which makes the radial length of the fire transfer gap 40 small, the fire transfer and flame stabilization capability is poor, and flameout is prone to occur.

[0122] When the ratio of the radial length of the upper plate upper section 22 to the total length of the upper plate upper section 22 and the upper plate lower section 23 is greater than 0.55, the radial length of the upper plate upper section 22 is larger, which makes the radial length of the fire transfer gap 40 larger, making it easier for the flame to flow back into the airway and cause a deflagration sound, thereby creating a safety hazard.

[0123] Similarly, in another embodiment, preferably, the ratio of the radial length a2 of the lower plate upper section 12 to the total length (a2+b2) of the lower plate upper section 12 and the lower plate lower section 13 can be in the range of (0.45, 0.55) (not shown) so that the fire transfer gap 40 has a better fire transfer and flame stabilization effect.

[0124] In some examples, The ratio can be 0.46, 0.48, 0.49, 0.50, 0.52, 0.53, 0.54 or other values ​​between 0.45 and 0.55.

[0125] When the ratio of the radial length of the lower plate upper section 12 to the total length of the lower plate upper section 12 and the lower plate lower section 13 is less than 0.45, the radial length of the lower plate upper section 12 is small, so that the radial length of the fire transfer gap 40 is small, the fire transfer and flame stabilization capability is poor, and flameout is prone to occur.

[0126] When the ratio of the radial length of the lower plate upper section 12 to the total length of the lower plate upper section 12 and the lower plate lower section 13 is greater than 0.55, the radial length of the lower plate upper section 12 is larger, which makes the radial length of the fire transfer gap 40 larger, making it easier for the flame to flow back into the airway and cause a deflagration sound, thereby creating a safety hazard.

[0127] In some embodiments, the gap between the upper plate section 22 and the partition plate 30 is in the range of (0, 3 mm); or

[0128] The gap between the lower plate upper section 12 and the partition plate 30 is in the range of (0, 3 mm).

[0129] In this way, it is ensured that the fire transfer gap 40 can achieve normal fire transfer and flame stabilization functions, thereby ensuring the normal operation of the burner 100.

[0130] Specifically, in one embodiment, the gap between the upper plate portion 22 and the partition plate 30 can be understood as the thickness of the fire transfer gap 40, that is, the gap between the upper plate portion 22 and the partition plate 30 should be of a suitable thickness to ensure that the fire transfer gap 40 can achieve normal fire transfer and flame stabilization functions, thereby improving a stable and uniform flame.

[0131] In one embodiment, the gap between the upper plate section 22 and the partition plate 30 may be in the range of (0, 3 mm). In some examples, the gap between the upper plate section 22 and the partition plate 30 may be 0.3 mm, 0.5 mm, 0.9 mm, 1.2 mm, 1.5 mm, 2.3 mm, 2.7 mm or other values ​​between 0 and 3 mm.

[0132] When the gap between the upper plate section 22 and the partition plate 30 is greater than 3 mm, the thickness of the fire transfer gap 40 is too large, which makes the inner cavity space of the fire transfer gap 40 too large, which easily causes the flow rate of the gas to be much greater than the combustion rate of the gas, resulting in incomplete combustion of the gas and too low combustion efficiency.

[0133] Similarly, in another embodiment, the gap between the upper portion 12 of the lower plate and the partition plate 30 can be understood as the thickness of the fire transfer gap 40, that is, the gap between the upper portion 12 of the lower plate and the partition plate 30 should be selected to have a suitable thickness to ensure that the fire transfer gap 40 can achieve normal fire transfer and flame stabilization functions, thereby improving a stable and uniform flame.

[0134] In one embodiment, the gap between the lower plate upper section 12 and the partition plate 30 may range from (0 to 3 mm). In some examples, the gap between the lower plate upper section 12 and the partition plate 30 may be 0.3 mm, 0.5 mm, 0.9 mm, 1.2 mm, 1.5 mm, 2.3 mm, 2.7 mm, or other values ​​between 0 and 3 mm.

[0135] When the gap between the upper section 12 of the lower plate and the partition plate 30 is greater than 3 mm, the thickness of the fire transfer gap 40 is too large, which makes the inner cavity space of the fire transfer gap 40 too large, which easily causes the flow rate of the gas to be much greater than the combustion rate of the gas, resulting in incomplete combustion of the gas and too low combustion efficiency.

[0136] In some embodiments, the gap between the upper plate section 22 and the partition plate 30 is in the range of (1 mm, 2 mm); or

[0137] The gap between the lower plate upper section 12 and the partition plate 30 is in the range of (1 mm, 2 mm).

[0138] In this way, a suitable gap is formed between the upper plate section 22 and the partition plate 30 , or a suitable gap is formed between the lower plate section 12 and the partition plate 30 , thereby improving the fire transfer and flame stabilization effect of the fire transfer gap 40 .

[0139] Specifically, in one embodiment, preferably, the gap range between the upper plate section 22 and the partition plate 30 can be (1 mm, 2 mm) to ensure that a suitable gap is formed between the upper plate section 22 and the partition plate 30, thereby improving the fire transfer and flame stabilization effect of the fire transfer gap 40.

[0140] In some examples, the gap between the upper plate section 22 and the partition plate 30 may be 1.1 mm, 1.3 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm or other values ​​between 1 mm and 2 mm.

[0141] When the gap between the upper plate section 22 and the partition plate 30 is greater than 2 mm, the thickness of the fire transfer gap 40 is relatively large, so that the inner cavity space of the fire transfer gap 40 is relatively large, which easily causes the flow rate of the gas to be greater than the combustion rate of the gas, resulting in incomplete combustion of the gas and low combustion efficiency.

[0142] When the gap between the upper plate section 22 and the partition plate 30 is less than 1 mm, the thickness of the fire transfer gap 40 is small, so that the inner cavity space of the fire transfer gap 40 is small, and the flow rate of the gas is lower than the combustion rate of the gas, which easily leads to flameout.

[0143] Similarly, in another embodiment, preferably, the gap range between the lower plate upper portion 12 and the partition plate 30 can be (1mm, 2mm) (not shown) to ensure that a suitable gap is formed between the lower plate upper portion 12 and the partition plate 30, thereby improving the fire transfer and flame stabilization effect of the fire transfer gap 40.

[0144] In some examples, the gap between the lower plate upper section 12 and the partition plate 30 may be 1.1 mm, 1.3 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm or other values ​​between 1 mm and 2 mm.

[0145] When the gap between the upper section 12 of the lower plate and the partition plate 30 is greater than 2 mm, the thickness of the fire transfer gap 40 is relatively large, so that the inner cavity space of the fire transfer gap 40 is relatively large, which easily causes the flow rate of the gas to be greater than the combustion rate of the gas, resulting in incomplete combustion of the gas and low combustion efficiency.

[0146] When the gap between the upper section 12 of the lower plate and the partition plate 30 is less than 1 mm, the thickness of the fire transfer gap 40 is small, so that the inner cavity space of the fire transfer gap 40 is small, and the flow rate of the gas is lower than the combustion rate of the gas, which easily leads to flameout.

[0147] In some embodiments, the lower plate 10, the partition plate 30 and the upper plate 20 are integrally formed of stainless steel sheets.

[0148] In this way, the lower plate 10, the partition plate 30 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.

[0149] Specifically, in one embodiment, the lower plate 10 can be used to form the fire hole 50, 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.

[0150] In one embodiment, the partition plate 30 can be used to separate the fire hole 50, so the partition plate 30 can be made of a high temperature resistant and corrosion resistant material. That is, the partition plate 30 can be integrally formed with a stainless steel material to shorten the production time and save production costs. In other embodiments, the partition plate 30 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.

[0151] Similarly, the upper plate 20 can be used to form the fire hole 50 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.

[0152] In one embodiment, the lower plate 10, the partition plate 30 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 has a smooth inner wall, thereby ensuring that the gas and air mixture can be transported smoothly, thereby improving the working efficiency of the burner 100.

[0153] In addition, the lower plate 10, the partition plate 30 and the upper plate 20 can be formed into a burner 100 by an integral molding method of stainless steel, so that the thickness of the lower plate 10 and the upper plate 20 is uniform, ensuring that the lower plate 10 and the upper plate 20 are heated uniformly, thereby improving the uniformity of the flames of the lower channel 11 and the upper channel 21.

[0154] In certain embodiments, the thicknesses of the lower plate 10, the partition plate 30, and the upper plate 20 are substantially the same.

[0155] In this way, the wall thickness of the burner 100 is ensured to be uniform, so that the burner 100 is heated evenly and has better stability.

[0156] Specifically, in one embodiment, the lower plate 10 , the partition plate 30 and the upper plate 20 are formed by welding stainless steel sheets having substantially the same thickness to improve the temperature consistency of the burner 100 , thereby ensuring safe use of the burner 100 .

[0157] It can be understood that the thicknesses of the lower plate 10, the partition plate 30 and the upper plate 20 are substantially the same, so that the inside of the burner 100 is heated evenly, thereby reducing safety phenomena such as fire leakage or explosion due to overheating in some locations.

[0158] In certain embodiments, the thickness of the lower plate 10, the partition plate 30, and the upper plate 20 is in the range of (0.5 mm, 2 mm).

[0159] In this way, the burner 100 is ensured to work normally and provide a uniform flame. When the thickness is less than 0.5 mm, the thickness of the lower plate 10, the partition plate 30 and the upper plate 20 is too thin, and it is easy to be overheated and cause deformation and fire leakage, which will cause safety hazards. When the thickness is greater than 2 mm, the thickness of the lower plate 10, the partition plate 30 and the upper plate 20 is too thick, the weight is large, and the production cost is high.

[0160] Specifically, in one embodiment, the lower plate 10, the partition plate 30 and the upper plate 20 should be of suitable thickness to ensure uniform flame of the burner 100, thereby providing a safe and stable working environment.

[0161] In one embodiment, the thickness of the lower plate 10, the partition plate 30 and the upper plate 20 may range from (0.5 mm to 2 mm). In some examples, the thickness of the lower plate 10, the partition plate 30 and the upper plate 20 may be 0.6 mm, 0.7 mm, 0.9 mm, 1.1 mm, 1.5 mm, 1.6 mm, 1.9 mm or other values ​​between 0.5 mm and 2 mm.

[0162] When the thickness of the lower plate 10 , the partition plate 30 , and the upper plate 20 is greater than 2 mm, the thickness of the lower plate 10 , the partition plate 30 , and the upper plate 20 is too large, so that the weight of the burner 100 is too large and the cost is too high.

[0163] When the thickness of the lower plate 10, the partition plate 30 and the upper plate 20 is less than 0.5 mm, the thickness of the lower plate 10, the partition plate 30 and the upper plate 20 is too thin, and it is easy to cause melting deformation and fire leakage due to excessive heat, thereby causing safety hazards.

[0164] In certain embodiments, the thickness of the lower plate 10, the partition plate 30, and the upper plate 20 is in the range of (0.8 mm, 1.5 mm).

[0165] In this way, a burner 100 with a suitable thickness is formed, thereby improving flame uniformity. When the thickness is less than 0.8 mm, the thickness of the lower plate 10, the partition plate 30 and the upper plate 20 is relatively thin, and it is easy to be deformed and leak fire due to high heat, which creates a safety hazard. When the thickness is greater than 1.5 mm, the thickness of the lower plate 10, the partition plate 30 and the upper plate 20 is relatively thick, the weight is large, and the production cost is high.

[0166] Specifically, in one embodiment, preferably, the thickness of the lower plate 10, the partition plate 30 and the upper plate 20 may be in the range of (0.8 mm, 1.5 mm). In some examples, the thickness of the lower plate 10, the partition plate 30 and the upper plate 20 may be 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm or other values ​​between 0.8 mm and 1.5 mm.

[0167] When the thickness of the lower plate 10 , the partition plate 30 , and the upper plate 20 is greater than 1.5 mm, the thickness of the lower plate 10 , the partition plate 30 , and the upper plate 20 is relatively large, so that the burner 100 is relatively heavy and the cost is relatively high.

[0168] When the thickness of the lower plate 10, the partition plate 30 and the upper plate 20 is less than 0.8 mm, the thickness of the lower plate 10, the partition plate 30 and the upper plate 20 is relatively thin, and it is easy to cause melting deformation and fire leakage due to excessive heat, thereby causing safety hazards.

[0169] See also Figure 1 and Figure 3 In some embodiments, the lower plate 10 is concave to form a lower channel 11, and the upper plate 20 is convex to form an upper channel 21. The lower channel 11 and the upper channel 21 are opposite to each other to form a fire hole 50 of the burner 100.

[0170] In this way, the fire holes 50 of the burner 100 are formed in a right-angled manner, thereby increasing the total area of ​​the fire holes 50 of the burner 100, and further increasing the flame intensity and load upper limit of the burner 100.

[0171] Specifically, the lower plate 10 can be used to form the fire hole 50, so the lower plate 10 can be made of a high temperature resistant and corrosion resistant material.

[0172] 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.

[0173] Similarly, the upper plate 20 can be used to form the fire hole 50 with the lower plate 10, so the upper plate 20 can be made of a high temperature resistant and corrosion resistant material.

[0174] 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.

[0175] 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 50. 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 50 is increased, so that the combustion amount of the gas is increased, thereby improving the flame intensity of the burner 100.

[0176] In addition, compared with a burner without a partition plate 30, the equivalent cross-sectional area of ​​the fire hole 50 of the present application does not change, which can ensure that the burner 100 has a larger flame and at the same time has excellent fire transfer and flame stabilization effects.

[0177] In some embodiments, the depth direction of the fire hole 50 forms an angle θ with the plane where the upper plate 20 is located, and the range of the angle θ is (0°, 90°).

[0178] In this way, the fire hole 50 of the burner 100 is inclined inwardly into a cone shape, thereby ensuring the flame gathering effect of the burner 100, thereby improving the flame intensity and heating efficiency of the burner 100.

[0179] Specifically, in one embodiment, the angle θ formed by the depth direction of the fire hole 50 and the plane where the upper plate 20 is located is in the range of (0°, 90°), so that the fire hole 50 of the burner 100 is inclined inward into a cone shape, thereby ensuring the flame gathering effect of the burner 100, and then improving the flame intensity of the burner 100 to ensure the heating rate of the bottom of the cooking utensil.

[0180] It can be understood that when the angle formed by the depth direction of the fire hole 50 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.

[0181] 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°.

[0182] In certain embodiments, the angle θ is in the range of (0°, 60°).

[0183] In this way, the flame focusing ability of the burner 100 is ensured, thereby improving the heating efficiency.

[0184] Specifically, in one embodiment, preferably, the angle θ formed by the depth direction of the fire hole 50 and the plane where the upper plate 20 is located is in the range of (0°, 60°), so that the fire hole 50 of the burner 100 is inclined inwardly into a cone shape, thereby ensuring that the flame formed by the fire hole 50 of the burner 100 better covers the bottom of the cooking utensil, thereby improving the heating rate of the burner 100.

[0185] It can be understood that when the angle formed by the depth direction of the fire hole 50 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.

[0186] 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°.

[0187] In certain embodiments, the angle θ is 40°.

[0188] 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.

[0189] Specifically, in one embodiment, preferably, the angle θ formed by the depth direction of the fire hole 50 and the plane where the upper plate 20 is located can be 40°. Under the condition that the fire hole 50 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.

[0190] 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 flame intensity and heating rate of the burner 100.

[0191] See also Figure 7 , an embodiment of the present invention provides a stove 1000, and the stove 1000 includes the burner 100 of the above embodiment.

[0192] In this way, the stove 1000 forms a fire transfer gap 40 between two adjacent independent upper channels 21, so that the flame between the upper plate 20 and the partition plate 30 is highly connectable to form a ring flame, thereby improving the burner 100's ability to transfer flames and anti-flashing capabilities during the ignition process, ensuring that the flame is not easily flamed out.

[0193] Specifically, in one embodiment, the stove 1000 may be a natural gas stove, a liquefied gas stove or a coal gas stove.

[0194] 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.

[0195] like Figure 7 As shown, Figure 7 It is a schematic structural diagram of a double-burner stove, where each burner 200 includes at least one burner 100 .

[0196] 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.

[0197] See also Figure 6 and Figure 8 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 .

[0198] In this way, the flame of the fire hole 50 formed by the cooperation between the lower channel 11 and the upper channel 21 is cohesive, while the flame's wrapping of the pot bottom is strengthened, the convection heat transfer coefficient is increased, the combustion efficiency is improved, the gas usage is saved, and it is green and environmentally friendly.

[0199] 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 51 of the plurality of lower channels 11 are dense and vigorous.

[0200] 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 51 of the plurality of upper channels 21 are dense and vigorous.

[0201] That is, the multiple lower channels 11 and the multiple upper channels 21 cooperate to form the multiple fire holes 50, so that the multiple fire holes 50 are distributed in a circular shape, so that the flames of the fire holes 50 are cohesive, and the combustion efficiency is improved. In addition, the multiple fire holes 50 are distributed in a circular shape, which strengthens the wrapping of the flame on the bottom of the pot, improves the convection heat transfer coefficient between the flame and the bottom of the pot, and thus saves the use of gas.

[0202] 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 .

[0203] In this way, the flame of the fire hole 50 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.

[0204] Specifically, Figure 8 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.

[0205] 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 51 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.

[0206] 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.

[0207] 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 51 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.

[0208] In summary, the flame of the fire hole 50 formed by the cooperation between the lower hole 11 and the upper hole 21 is concentrated, making the flame more vigorous, thereby improving the combustion efficiency of the fuel gas.

[0209] In some embodiments, the lower plate 10 includes a lower plate upper portion 12, the lower channel 11 is formed in the lower plate upper portion 12, and the lower plate upper portion 12 is arched radially from the outside to the inside toward the upper plate 20. The upper plate 20 includes an upper plate upper portion 22, the upper channel 21 is formed in the upper plate upper portion 22, and the upper plate upper portion 22 is arched radially from the outside to the inside toward the direction away from the lower plate 10.

[0210] In this way, the lower plate upper portion 12 and the upper plate upper portion 22 are arranged in the same direction to ensure that they cooperate with each other to form a plurality of fire holes 50 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 50 are closer to the bottom of the pot, thereby improving the heat transfer efficiency between the flame and the bottom of the pot.

[0211] Specifically, Figure 6 and Figure 8 As shown, in one embodiment, the lower plate upper section 12 is arranged in a circular ring shape, and the lower plate upper section 12 is arched radially from the outside to the inside toward the upper plate 20 to support the upper plate upper section 22 to improve the stability of the upper plate upper section 22.

[0212] like Figure 6 and Figure 8As shown, the upper plate upper section 22 is arranged in a circular ring shape, and the upper plate upper section 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 lower plate upper section 12 to form a plurality of fire holes 50 distributed in a circular ring shape, so that the fire holes 50 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.
