Description

Technical Field

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

[0002] Existing gas stove burners typically consist of a gas distribution seat and a burner cap. The burner cap sits atop the gas distribution seat, and its surface has multiple flame holes for gas to be ejected, thus forming a flame. To create a larger flame heating surface and improve thermal efficiency, existing stoves usually have more flame holes on the top of the burner cap. However, an excessively high density of flame holes restricts the complete mixing of secondary air, leading to incomplete combustion and the production of harmful gases such as carbon monoxide and nitrogen oxides. This increases flue gas emissions and, conversely, limits further improvements in the stove's thermal efficiency.

[0003] Therefore, there is an urgent need for a burner with a reasonable layout of flame holes to fully replenish secondary air and improve the thermal efficiency of the stove. Utility Model Content

[0022] The beneficial effects of this utility model are:

[0023] In the burner provided by this utility model, the amount of secondary air supply is increased by setting multiple air supply grooves that run through the axis, thereby providing sufficient secondary air to the first flame outlet on the top surface of the gas distribution seat.

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0042] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0044] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0045] This embodiment provides a burner that can better replenish secondary air and rationally arrange more flame holes to improve combustion efficiency.

[0046] Specifically, such as Figure 1 and Figure 2 As shown, the burner includes a gas distribution base 100, within which a gas distribution chamber is provided. The gas distribution chamber is used to introduce a mixture of fuel gas and air. Multiple first flame outlets are provided on the top surface of the gas distribution base 100, and these first flame outlets communicate with the gas distribution chamber. When the mixture is introduced into the gas distribution chamber and ignited by an ignition needle, the burner can form a flame at the first flame outlet to achieve a cooking effect.

[0047] To increase the flame heating surface, the number of first flame outlets is maximized. To ensure sufficient air for combustion at the first flame outlets, the gas distributor 100 is equipped with multiple air supply grooves 40, which are through grooves extending along the axial direction of the gas distributor 100. By providing air supply grooves 40, air can be supplied to the first flame outlets more fully, ensuring complete combustion of the fuel gas. Simultaneously, because the air supply grooves 40 can adequately supply secondary air, the number of first flame outlets on the gas distributor 100 can be arranged more densely and extensively, thereby increasing the flame heating surface and improving thermal efficiency.

[0048] It should be noted that the axial direction of the air distribution seat 100 is vertical. That is to say, the top end of the air supply groove 40 penetrates the top surface of the air distribution seat 100, and the bottom end of the air supply groove 40 penetrates the bottom surface of the air distribution seat 100. Air can enter the air supply groove 40 from the top and bottom surfaces to supplement the first ignition hole with secondary air.

[0049] To ensure complete combustion and improve thermal efficiency, multiple ignition holes are provided on the inner wall of the air supply groove 40 and the side of the air distribution seat 100, and these ignition holes are connected to their adjacent first ignition holes. By providing ignition holes, on the one hand, it is possible to better replenish the air outside the air distribution seat 100 and inside the air supply groove 40, and on the other hand, it is possible to divert some of the gas at the first ignition hole to ensure complete combustion of the gas and improve combustion efficiency.

[0050] In other embodiments, flame distribution holes may be provided only on the inner wall of the gas supply groove 40 or only on the side of the gas distribution seat 100, which can also achieve the effect of diverting gas flow and ensuring complete combustion and secondary air replenishment.

[0051] In some embodiments, at least some of the first flame outlets are provided with flame distribution holes on both opposite sides, which communicate with them. That is, at least some of the first flame outlets are provided with two flame distribution holes, which are located between the two flame distribution holes and communicate with the two flame distribution holes respectively, so as to divert the gas to both sides to ensure complete combustion and increase the flame heating surface.

[0052] To increase the number of air supply slots 40, in some embodiments, multiple air supply slots 40 are arranged at intervals along the circumference of the air distribution seat 100. On the one hand, this can increase the number of air supply slots 40, and on the other hand, it can ensure that each first flame outlet is surrounded by an air supply slot 40, thereby reducing the distance between the first flame outlet and the air supply slot 40 and improving the secondary air supply effect.

[0053] like Figures 1-3 As shown, in some embodiments, the gas distributor 100 includes two annular portions and multiple connecting portions 30. The two annular portions are nested and are respectively an inner ring portion 10 and an outer ring portion 20. The multiple connecting portions 30 are located between the inner ring portion 10 and the outer ring portion 20 and are spaced apart along the circumference of the gas distributor 100. The two ends of the connecting portions 30 are respectively connected to the inner ring portion 10 and the outer ring portion 20. Two adjacent connecting portions 30 cooperate with the two annular portions to form a replenishment groove 40. This arrangement makes the replenishment grooves 40 more evenly distributed, and the distance between each first ignition hole and the replenishment groove 40 is smaller, thereby improving the replenishment effect of secondary air.

[0054] In some embodiments, the width of the connecting portion 30 is the same along the radial direction of the air distributor 100, so that the width of the enclosed air supply groove 40 gradually increases along the radial direction of the air distributor 100 away from the center of the air distributor 100. That is, the end of the air supply groove 40 near the center of the air distributor 100 is narrow, and the end away from the center of the air distributor 100 is wide.

[0055] In other embodiments, more than two annular portions may be provided, such as three, four or more, with multiple annular portions nested together. Multiple connecting portions 30 are provided between any two adjacent annular portions, so that multiple air replenishment grooves 40 are formed between any two adjacent annular portions.

[0056] To increase the number of first flame outlets on the gas distribution seat 100, in some embodiments, the top surface of each annular portion and the top surface of each connecting portion 30 are provided with first flame outlets, so as to reasonably arrange the number of first flame outlets and increase the flame heating surface.

[0057] like Figure 1 , Figure 4 and Figure 5 As shown, the first ignition port includes a circumferential ignition port and a radial ignition port 31. Multiple circumferential ignition ports are arranged circumferentially on the top surface of the annular portion. The circumferential ignition ports include an outer ring ignition port 21 on the top surface of the outer ring portion 20 and an inner ring ignition port 11 on the top surface of the inner ring portion 10. Multiple radial ignition ports 31 are arranged radially on the top surface of the connecting portion 30 along the radial direction of the gas distributor 100 to make the distribution of the first ignition port more uniform.

[0058] Optionally, the top surface of the annular portion may have a ring of circumferential flame holes arranged in a circular pattern, or it may have two, three or more nested rings of circumferential flame holes; the top surface of the connecting portion 30 may have a row of radial flame holes 31 arranged in a radial direction, or it may have two, three or more rows of radial flame holes 31.

[0059] In other embodiments, the first flame outlet may be provided only on the top surface of the connecting portion 30, or only on the top surface of at least one annular portion, or the first flame outlet may be provided on the top surfaces of the connecting portion 30 and part of the annular portion.

[0060] To improve combustion efficiency, in some embodiments, such as Figures 6-9 As shown, flame distribution holes are provided on the opposite two circumferential sidewalls of the annular portion and on the opposite two sidewalls of the connecting portion 30. The flame distribution holes can communicate with the adjacent first flame outlet holes to divert the gas and improve the combustion effect of the gas.

[0061] Specifically, such as Figure 6 and Figure 9 As shown, radial flame distribution holes 32 are provided on the opposite side walls of the connecting part 30. The radial flame distribution holes 32 are connected to the corresponding radial flame outlet holes 31 on the connecting part 30, so that at least part of the radial flame outlet holes 31 are connected to the radial flame distribution holes 32 on both sides respectively, forming a three-way flame outlet structure, thereby increasing the flame heating surface, realizing the three-way diversion of gas, facilitating the replenishment of secondary air, and ensuring the complete combustion of gas.

[0062] Similarly, such as Figure 1 , Figure 7 and Figure 8 As shown, the inner ring portion 10 has inner ring flame distribution holes 12 on its opposite circumferential sidewalls. The inner ring flame distribution holes 12 are connected to the corresponding inner ring flame outlet holes 11 on the top surface of the inner ring portion 10, so that at least a portion of the inner ring flame outlet holes 11 are connected to the inner ring flame distribution holes 12 on both sides, forming a three-pronged flame outlet structure. The outer ring portion 20 has outer ring flame distribution holes 22 on its opposite circumferential sidewalls. The outer ring flame distribution holes 22 are connected to the corresponding outer ring flame outlet holes 21 on the top surface of the outer ring portion 20, so that at least a portion of the outer ring flame outlet holes 21 are connected to the outer ring flame distribution holes 22 on both sides, forming a three-pronged flame outlet structure. This increases the flame heating surface, realizes the three-pronged diversion of the gas, facilitates the replenishment of secondary air, and ensures the complete combustion of the gas.

[0063] In some embodiments, the flame distribution hole is inclined. Specifically, the flame distribution hole extends vertically and horizontally from the outside to the inside, so that the flame hole at the flame distribution hole is close to the top of the gas distribution seat 100, ensuring contact between the flame and the stove. In other embodiments, the flame distribution hole may extend upwards and horizontally from the outside to the inside.

[0064] To ensure that the gas distributor 100 supplies mixed gas to each ignition hole, the annular portion and the connecting portion 30 are hollow to form a gas distribution chamber, thereby introducing a mixture of fuel gas and air into the corresponding first ignition hole.

[0065] In some embodiments, such as Figures 10-12 As shown, the gas distribution chamber includes an inner ring gas distribution chamber 13, an outer ring gas distribution chamber 23, and a radial gas distribution chamber 33. The inner ring 10 is hollow to form the inner ring gas distribution chamber 13, the outer ring 20 is hollow to form the outer ring gas distribution chamber 23, and the connecting part 30 is hollow to form the radial gas distribution chamber 33, so as to make the supply of the gas mixture of fuel gas and air more sufficient and improve thermal efficiency.

[0066] In some embodiments, the two ends of the radial gas distribution chamber 33 are connected to the outer ring gas distribution chamber 23 and the inner ring gas distribution chamber 13 respectively, to ensure that the mixed gas in the gas distribution seat 100 is evenly distributed, so that the flame at each first flame outlet is more uniform.

[0067] In some embodiments, reference is made to Figure 1 and Figure 2 As shown, the gas distribution seat 100 is integrally molded. Compared with traditional burners, it eliminates the need for an outer ring flame cap, which helps reduce the number of parts and lowers assembly time and cost.

[0068] In other embodiments, the gas distribution seat 100 may include a seat body and an outer ring flame cap. The seat body is provided with a gas distribution groove, and the outer ring flame cap is connected to the seat body and can cover the top opening of the gas distribution groove, so that the outer ring flame cap and the gas distribution groove on the seat body can form a gas distribution chamber.

[0069] In some embodiments, the gas distribution seat 100 further includes a venting port 50, which is connected to the gas distribution chamber and is used to introduce a mixture of fuel gas and air into the gas distribution chamber for combustion.

[0070] Optionally, multiple vent ports 50 can be provided, with the multiple vent ports 50 spaced apart circumferentially along the gas distribution seat 100. By increasing the number of vent ports 50, the mixed gas distribution in the gas distribution chamber can be made more uniform, ensuring uniform flame distribution.

[0071] For example, four vent ports 50 are provided, and the four vent ports 50 are connected to the inner ring gas distribution chamber 13, through which mixed gas is introduced into the radial gas distribution chamber 33 and the outer ring gas distribution chamber 23. In other embodiments, the number and connection positions of the vent ports 50 can be adjusted according to actual needs.

[0072] In some embodiments, the gas distribution seat 100 includes a central seat 60 with an inner ring gas distribution groove. The burner also includes an inner ring flame cap 200, which is connected to the central seat 60 and forms an inner ring cavity 61 with the inner ring gas distribution groove. The inner ring flame cap 200 has a second flame outlet 201 communicating with the inner ring cavity 61. By providing the inner ring gas distribution groove and the inner ring flame cap 200, the burner can form an inner ring flame during operation, further increasing the flame heating surface and improving the cooking effect.

[0073] It should be noted that the inner ring gas distribution groove and the inner ring burner cap 200 are existing technologies in this field, and their specific structures and connections will not be described here.

[0074] This embodiment also provides a stove, including a stovetop and the aforementioned burner. The burner is mounted on the stovetop and is used to generate flames for cooking. The stove in this embodiment uses the aforementioned burner, which allows for a more efficient arrangement of fire holes, sufficient replenishment of secondary air, an increased flame heating surface, and improved thermal efficiency.

[0075] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
