Description

Technical Field

[0001] This application relates to the field of burner technology, and in particular to a fully top-intake gas stove. Background Technology

[0002] A gas stove is a kitchen appliance that uses liquefied petroleum gas, manufactured gas, natural gas, or other gaseous fuels for direct-fire heating. Based on the method of primary air supply, gas stoves can be divided into full-air-intake gas stoves and fully top-air-intake gas stoves. Fully top-air-intake gas stoves obtain both primary and secondary air from above the cooktop, eliminating the need for ventilation holes in cabinets or the stove casing. This reduces the risk of foreign objects entering the stove and causing blockages in the gas pipes, thus lowering the risk of gas leaks and providing higher safety.

[0003] In related technologies, a fully top-intake gas stove includes a burner and a base. The base is located on one side of the burner and connected to it to provide support. However, the structure of the base is relatively complex and not easy to clean, making the cleaning of a fully top-intake gas stove difficult. Summary of the Invention

[0004] This application provides a fully top-intake gas stove that reduces the difficulty of cleaning.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] This application provides a fully top-intake gas stove, which includes a burner and a base.

[0007] The burner head has a first mixing chamber and a second mixing chamber. The base includes a top plate, a first ejector tube, a second ejector tube, a first nozzle, and a second nozzle. The top plate is located on one side of the burner head and connected to it. The first ejector tube, the second ejector tube, the first nozzle, and the second nozzle are all located on the side of the top plate away from the burner head and connected to the top plate. The first ejector tube communicates with the first mixing chamber, and the second ejector tube communicates with the second mixing chamber. The first nozzle and the first ejector tube are coaxially aligned, and the second nozzle and the second ejector tube are coaxially aligned.

[0008] The base of the fully top-intake gas stove provided in this embodiment includes a top plate, a first ejector tube, a second ejector tube, a first nozzle, and a second nozzle, all of which are located on the side of the top plate away from the burner. It is understood that when cleaning the base of a fully top-intake gas stove, typically only the exposed portion of the base needs cleaning, primarily the surface near the burner. By arranging the first ejector tube, second ejector tube, first nozzle, and second nozzle all on the side of the top plate away from the burner, the structure of the surface of the top plate near the burner is simplified, resulting in a smoother surface. This reduces the difficulty of cleaning the base, thereby reducing the overall cleaning difficulty of the fully top-intake gas stove.

[0009] In some embodiments, the top plate is provided with a first air intake, and the base further includes a first baffle plate and a first cover plate. The first baffle plate is disposed on the side of the top plate away from the burner head and is connected to the top plate. The first baffle plate is arranged circumferentially around the first air intake. The first cover plate is connected to the first baffle plate and, together with the first baffle plate and the top plate, forms a first ejector cavity. The two ends of the first ejector tube and the first nozzle that are close to each other are located within the first ejector cavity.

[0010] In some embodiments, the base further includes a first baffle, which is disposed on the side of the top plate near the burner head and connected to the top plate. The first baffle is arranged around the first air intake.

[0011] In some embodiments, the end of the first baffle away from the top plate abuts against the burner head, and the first baffle is provided with a first air inlet, which is located at the end of the first baffle away from the top plate.

[0012] In some embodiments, a second air intake is provided on the top plate, and the base further includes a second baffle plate and a second cover plate. The second baffle plate is disposed on the side of the top plate away from the burner head and is connected to the top plate. The second baffle plate is arranged circumferentially around the second air intake. The second cover plate is connected to the second baffle plate and, together with the second baffle plate and the top plate, forms a second ejector cavity. The two ends of the second ejector tube and the second nozzle, which are close to each other, are located within the second ejector cavity.

[0013] In some embodiments, the base further includes a second baffle, which is disposed on the side of the top plate near the burner head and connected to the top plate. The second baffle is arranged around the second air intake.

[0014] In some embodiments, the end of the second baffle away from the top plate abuts against the burner head, and the second baffle is provided with a second air intake opening, which is located at the end of the second baffle away from the top plate.

[0015] In some embodiments, the axis of the first ejector tube is parallel to the surface of the top plate away from the furnace head, and the axis of the second ejector tube is parallel to the surface of the top plate away from the furnace head. A first direction is defined as the direction along the axis of the first ejector tube pointing from the first ejector tube to the first nozzle, and a second direction is defined as the direction along the axis of the second ejector tube pointing from the second ejector tube to the second nozzle. The angle between the first direction and the second direction is less than or equal to 30°.

[0016] In some embodiments, the axis of the first ejector tube and the axis of the second ejector tube are parallel.

[0017] In some embodiments, the axis of the first ejector tube is located on the side of the second ejector tube away from the top plate. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, 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 application.

[0037] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0038] It should be noted that in practical applications, due to limitations in equipment precision or installation errors, achieving absolute parallelism or perpendicularity is difficult. The descriptions of "perpendicular," "parallel," or "in the same direction" in this application are not absolute limitations, but rather indicate that a vertical or parallel structural arrangement can be achieved within a preset error range, achieving the corresponding preset effect. This maximizes the technical effect of the defined features and makes the corresponding technical solution easy to implement, possessing high feasibility. For example, "perpendicular" includes absolute perpendicularity and near-perpendicularity, where the acceptable deviation range for near-perpendicularity can be, for example, within 5°. "Parallel" includes absolute parallelism and near-parallelism, where the acceptable deviation range for near-parallelism can also be, for example, within 5°. "In the same direction" includes absolute same direction and near-same direction, where the acceptable deviation range for near-same direction can also be, for example, within 5°.

[0039] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a direct connection or an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0040] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0041] In the embodiments of this application, the words "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of the words "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0042] Gas stoves can be categorized into two types based on their primary air supply method: full-air intake gas stoves and fully top-air intake gas stoves. Full-air intake gas stoves supply primary air from below the cooktop, while fully top-air intake gas stoves supply primary air from above. When using a full-air intake gas stove, ventilation holes must be provided in the cabinet and the stove casing to ensure sufficient primary air supply. However, these ventilation holes are prone to blockage, leading to insufficient primary air supply, incomplete combustion, excessive carbon monoxide levels, and a tendency to produce a yellow flame. Furthermore, small insects and other foreign objects can easily enter the stove casing through the ventilation holes, clogging the gas pipes and increasing the risk of gas leaks. Fully top-air intake gas stoves, on the other hand, do not require ventilation holes in the cabinet or stove casing, offering higher safety and gaining popularity in the market.

[0043] In related technologies, a fully top-intake gas stove includes an interconnected burner head and a base. The burner head includes a mixing chamber and an injector tube communicating with the mixing chamber. The base has a nozzle corresponding to the injector tube and a support structure for supporting the burner head. The surface of the base near the burner head has a complex structure, making cleaning difficult. Furthermore, when the fully top-intake gas stove includes a drip tray, the drip tray needs to have clearance holes to avoid obstructing the structure on the base surface near the burner head, which is detrimental to the design of the drip tray.

[0044] Based on this, such as Figure 1 As shown, Figure 1 This is a structural diagram of a fully top-intake gas stove provided in some embodiments of this application. This disclosure provides a fully top-intake gas stove 100, which reduces the difficulty of cleaning the stove and simplifies the design of the drip tray. The fully top-intake gas stove 100 includes a burner head 1 and a base 2.

[0045] Among them, such as Figure 2 As shown, Figure 2 This is a cross-sectional view of a fully top-intake gas stove provided in some embodiments of this application. The burner head 1 has a first mixing chamber 11 and a second mixing chamber 12. The base 2 is disposed on one side of the burner head 1 and connected to the burner head 1 to provide support for the burner head 1.

[0046] It is understood that the burner head 1 can be either a split structure or an integrated structure, and the choice can be made according to the actual situation. This disclosure does not make any specific restrictions on this.

[0047] For example, such as Figure 3 As shown, Figure 3 This is an exploded view of the burner head provided in some embodiments of this application. The burner head 1 has a split structure. This design makes it easy to disassemble the burner head 1 for cleaning, which helps to reduce the cleaning difficulty of the burner head 1, and thus reduces the cleaning difficulty of the fully top-intake gas stove 100.

[0048] Based on this, see Figure 3 The burner head 1 includes a first burner cap 13, a second burner cap 14, and a flame distributor 15. The first burner cap 13 and the second burner cap 14 are positioned away from the base 2 of the flame distributor 15 (e.g., Figure 2 (as shown) on one side, and connected to the fire distributor 15.

[0049] The first flame cap 13 and the flame distributor 15 form the first mixing chamber 11 (e.g., Figure 2 As shown), and the first flame cap 13 is provided with a first flame outlet 131 communicating with the first mixing chamber 11; the second flame cap 14 and the flame distributor 15 form a second mixing chamber 12 (as shown). Figure 2 As shown), and the second flame cap 14 is provided with a second flame outlet 141 that communicates with the second mixing chamber 12.

[0050] It is understandable that the first flame cap 13 is usually provided with multiple first flame outlet holes 131, and the second flame cap 14 is usually provided with multiple second flame outlet holes 141.

[0051] For example, such as Figure 1 As shown, the first flame cap 13 is arranged circumferentially around the second flame cap 14. In this case, a plurality of first flame outlets 131 are arranged around a plurality of second flame outlets 141. This facilitates the replenishment of secondary air.

[0052] It should be noted that the first burner cap 13 and the second burner cap 14 can be coaxial or non-coaxial, depending on the actual situation, and this disclosure does not impose specific limitations on this. For example, the first burner cap 13 and the second burner cap 14 can be coaxial. In this way, when using the fully top-intake gas stove 100 to heat the cookware, it is beneficial to make the cookware heat more evenly, which can improve the cooking effect.

[0053] In some embodiments, such as Figure 4 As shown, Figure 4 This is a cross-sectional view of a base provided in some embodiments of this application. The base 2 includes a top plate 21, a first ejector tube 22, and a second ejector tube 23. The top plate 21 is disposed on the burner head 1 (e.g., Figure 2The first ejector tube 22 and the second ejector tube 23 are located on one side of the top plate 21 away from the burner head 1 and are connected to the top plate 21. The first ejector tube 22 is connected to the first mixing chamber 11 (as shown in the image). Figure 2 (as shown) is connected, the second ejector tube 23 is connected to the second mixing chamber 12 (as shown) Figure 2 (As shown) connected.

[0054] In this configuration, the gas and air ejected by the first ejector tube 22 flow into the first mixing chamber 11 through the first ejector tube 22, and after being mixed evenly, flow out through the first ignition hole 131 communicating with the first mixing chamber 11, and are then ignited to form a flame. Similarly, the gas and air ejected by the second ejector tube 23 flow into the second mixing chamber 12 through the second ejector tube 23, and after being mixed evenly, flow out through the second ignition hole 141 communicating with the second mixing chamber 12, and are then ignited to form a flame.

[0055] Understandably, when cleaning the base 2 of the fully enclosed gas stove 100, it is usually only necessary to clean the exposed part of the base 2, mainly the surface of the base 2 on the side near the burner 1.

[0056] Based on this, placing the first ejector tube 22 and the second ejector tube 23 on the side of the top plate 21 away from the burner 1 simplifies the structure of the surface of the top plate 21 near the burner 1, making the surface of the base 2 near the burner 1 relatively flat. This helps reduce the cleaning difficulty of the base 2, thereby reducing the cleaning difficulty of the fully top-intake gas stove 100.

[0057] Based on this, see Figure 4 The base 2 may also include a first nozzle 24 and a second nozzle 25, which are connected to the top plate 21. The first nozzle 24 corresponds to the position of the first ejector tube 22, and the second nozzle 25 corresponds to the position of the second ejector tube 23.

[0058] It should be noted that the corresponding positions of the first nozzle 24 and the first ejector tube 22 mean that the first nozzle 24 is located within the opening range of the first ejector tube 22. In this way, the gas ejected from the first nozzle 24 can directly enter the first ejector tube 22. Similarly, the corresponding positions of the second nozzle 25 and the second ejector tube 23 mean that the second nozzle 25 is located within the opening range of the second ejector tube 23. In this way, the gas ejected from the second nozzle 25 can directly enter the second ejector tube 23.

[0059] In this scenario, when the first nozzle 24 injects gas into the first ejector tube 22, air near the opening of the first ejector tube 22 is drawn into the first ejector tube 22 along with the gas. This air is then used as primary air to flow into the first mixing chamber 11 along with the gas through the first ejector tube 22. After being mixed evenly, it flows out through the first ignition hole 131, which communicates with the first mixing chamber 11, and is subsequently ignited to form a flame. Similarly, when the second nozzle 25 injects gas into the second ejector tube 23, air near the opening of the second ejector tube 23 is drawn into the second ejector tube 23 along with the gas. This air is then used as primary air to flow into the second mixing chamber 12 along with the gas through the second ejector tube 23. After being mixed evenly, it flows out through the second ignition hole 141, which communicates with the second mixing chamber 12, and is subsequently ignited to form a flame.

[0060] For example, such as Figure 5 As shown, Figure 5 This is a structural diagram of a fully top-intake gas stove provided in some embodiments of this application. The first nozzle 24 and the second nozzle 25 are both located on the side of the top plate 21 away from the burner 1 and are connected to the top plate 21. It is understood that placing the first nozzle 24 and the second nozzle 25 on the side of the top plate 21 away from the burner 1 further simplifies the structure of the surface of the top plate 21 near the burner 1, thereby making the surface of the base 2 near the burner 1 flatter. This further reduces the difficulty of cleaning the fully top-intake gas stove 100.

[0061] Based on this, see Figure 4 The first nozzle 24 can be coaxially arranged with the first ejector tube 22. This reduces the risk of gas leakage when the first nozzle 24 injects gas into the first ejector tube 22, while simultaneously increasing the ejector tube 22's ability to eject primary air, thereby improving the safety and combustion performance of the fully top-intake gas stove 100. Similarly, the second nozzle 25 can be coaxially arranged with the second ejector tube 23. This also reduces the risk of gas leakage when the second nozzle 25 injects gas into the second ejector tube 23, while simultaneously increasing the second ejector tube 23's ability to eject primary air, thereby improving the safety and combustion performance of the fully top-intake gas stove 100.

[0062] In some embodiments, such as Figure 5 As shown, the axes of the first ejector tube 22 and the second ejector tube 23 are both parallel to the surface of the top plate 21 away from the burner head 1. This helps to reduce the space occupied by the first ejector tube 22 and the second ejector tube 23 in the direction perpendicular to the surface of the top plate 21 away from the burner head 1.

[0063] Based on this, see Figure 6 , Figure 6A cross-sectional view of the base provided in some embodiments of this application. Along the first ejector tube 22 (e.g.) Figure 4 The first direction X is defined as the axis of the first ejector tube 22 pointing to the first nozzle 24, and the second direction Y is defined as the axis of the second ejector tube 23 pointing to the second nozzle 25. The angle α between the first direction X and the second direction Y is less than or equal to 30°.

[0064] This arrangement allows the openings of the first ejector tube 22 and the second ejector tube 23 to be concentrated on the same side of the base 2, which facilitates the centralized arrangement of the first nozzle 24 and the second nozzle 25. This also provides convenience for the installation of the gas pipeline.

[0065] For example, such as Figure 6 As shown, the angle α between the first direction X and the second direction Y can be any one of 0°, 5°, 10°, 15°, 20°, 25° and 30°. The specific angle can be selected according to the actual situation, and this disclosure does not make any specific limitation.

[0066] For example, the angle α between the first direction X and the second direction Y is 0°. In this case, as... Figure 7 As shown, Figure 7 This is a structural diagram of the base provided for some embodiments of this application. The axis of the first ejector tube 22 is parallel to the axis of the second ejector tube 23. This arrangement helps to reduce the space occupied by the first ejector tube 22 and the second ejector tube 23 in the direction parallel to the surface of the top plate 21 away from the furnace head 1.

[0067] At this time, as Figure 5 As shown, the axis of the first ejector tube 22 can be positioned on the side of the second ejector tube 23 away from the top plate 21; or the axis of the second ejector tube 23 can be positioned on the side of the top plate 21 closer to the top plate 21; or the distance between the axis of the first ejector tube 22 and the surface of the top plate 21 away from the burner head 1 can be set to be equal to the distance between the axis of the second ejector tube 23 and the surface of the top plate 21 away from the burner head 1. The specific choice can be made according to the actual situation, and this disclosure does not impose any specific limitations on this.

[0068] For example, see Figure 5 The axis of the first ejector tube 22 is positioned on the side away from the axis of the second ejector tube 23, away from the top plate 21. This reduces the risk of gas pipeline crossings, thereby simplifying the installation of the gas pipeline system.

[0069] In some embodiments, such as Figure 8 As shown, Figure 8 This is a structural diagram of a burner head provided in some embodiments of this application. The burner head 1 is provided with a first air inlet 16, and the first air inlet 16 is connected to the first mixing chamber 11 (e.g., Figure 2 (As shown) Connectivity. See also Figure 9 , Figure 9 This is a structural diagram of a base provided in some embodiments of this application. A first air outlet 211 is provided on the top plate 21, and the first air outlet 211 is connected to the first air inlet 16.

[0070] Based on this, see Figure 10 , Figure 10 This is a structural diagram of a base provided in some embodiments of this application. The base 2 also includes a side plate 26 and a bottom plate 27. The side plate 26 is disposed on the side of the top plate 21 away from the burner head 1 and is connected to the top plate 21. The side plate 26 is arranged circumferentially around the first gas outlet 211. The bottom plate 27 is connected to the side plate 26 and, together with the side plate 26 and the top plate 21, forms a first premixing chamber 28 (e.g., ...). Figure 2 As shown). First ejector tube 22 (as shown) Figure 4 (As shown) is connected to the first premixing chamber 28.

[0071] In this case, the primary air and fuel gas ejected by the first ejector tube 22 will first flow into the first premixing chamber 28 for preliminary mixing, then flow through the first air outlet 211 and the first air inlet 16 into the first mixing chamber 11 for further uniform mixing, and finally flow out through the first ignition hole 131 and be ignited.

[0072] This configuration allows for a more uniform mixing of primary air and fuel gas ejected by the first ejector tube 22, which promotes complete combustion of the fuel gas at the first ignition port 131. This reduces the risk of excessive carbon monoxide levels or the appearance of a yellow flame.

[0073] It should be noted that the top plate 21, side plate 26, and bottom plate 27 can be integrally formed, or they can be three independent components connected into a whole by welding, bonding, or other methods. The specific choice can be made according to the actual situation, and this disclosure does not impose any specific limitations.

[0074] For example, such as Figure 10 As shown, the top plate 21, side plate 26, and bottom plate 27 are integrally formed. This arrangement helps to improve the airtightness of the first premixing chamber 28, thereby reducing the risk of gas leakage and further improving the safety of the fully top-intake gas stove 100.

[0075] Based on this, see Figure 4 The side plate 26 may include a first sub-side plate 261, a second sub-side plate 262, a third sub-side plate 263, and a fourth sub-side plate 264.

[0076] For example, such as Figure 4As shown, the first sub-side plate 261 has a first mounting hole, and the first ejector tube 22 passes through the first mounting hole. It can be understood that the outer surface of the first ejector tube 22 is in contact with the inner surface of the first mounting hole; that is, there is no gap between the surfaces of the first ejector tube 22 and the first mounting hole that are close to each other. The first premixing chamber 28 (as shown) Figure 2 The gas inside (as shown) cannot leak out between the surfaces of the first ejector tube 22 and the first mounting hole that are close to each other.

[0077] Based on this, the second sub-side plate 262 is disposed opposite to the first sub-side plate 261, and the first air outlet 211 is located between the first sub-side plate 261 and the second sub-side plate 262. The axis of the first ejector tube 22 is perpendicular to the surface of the second sub-side plate 262 near the first sub-side plate 261, and the orthographic projection of the first ejector tube 22 on the surface of the second sub-side plate 262 near the first sub-side plate 261 is located within the boundary of the second sub-side plate 262.

[0078] With this configuration, the air and fuel gas flowing into the first premixing chamber 28 from the first ejector tube 22 will first impact the second sub-side plate 262, and then diffuse to other areas of the first premixing chamber 28. This allows the air and fuel gas to mix more evenly within the first premixing chamber 28, which is beneficial for complete combustion of the fuel gas.

[0079] The third sub-side plate 263 is disposed on the side of the first ejector tube 22 away from the first air outlet 211, and is connected to the first sub-side plate 261 and the second sub-side plate 262. The fourth sub-side plate 264 is disposed opposite to the third sub-side plate 263, and is connected to the first sub-side plate 261 and the second sub-side plate 262. The first air outlet 211 is located between the third sub-side plate 263 and the fourth sub-side plate 264.

[0080] That is, the first air outlet 211 is surrounded by the first sub-side plate 261, the second sub-side plate 262, the third sub-side plate 263, and the fourth sub-side plate 264. At this time, the first premixing chamber 28 is formed by the first sub-side plate 261, the second sub-side plate 262, the third sub-side plate 263, the fourth sub-side plate 264, the bottom plate 27, and the top plate 21.

[0081] In some embodiments, such as Figure 4 As shown, the axis of the first ejector tube 22 is located around the first air outlet 211. That is to say, the first ejector tube 22 is not directly facing the first air outlet 211.

[0082] This configuration reduces the risk that the gas and air injected into the first premixing chamber 28 by the first ejector tube 22 will not be premixed and will flow out of the first premixing chamber 28 through the first outlet 211. This promotes a more uniform mixing of air and gas, resulting in more complete combustion.

[0083] In this case, the surface of the third sub-side plate 263 near the fourth sub-side plate 264 can be configured to be perpendicular to the surface of the top plate 21 near the side plate 26 and tangent to the inner surface of the first ejector tube 22.

[0084] In this way, with the dimensions of the first ejector tube 22 and the first premixing chamber 28 being fixed, the axis of the first ejector tube 22 can be further away from the first gas outlet 211. This arrangement allows the fuel gas and air to remain in the first premixing chamber 28 for a longer period, resulting in a more uniform mixture.

[0085] In some embodiments, such as Figure 11 As shown, Figure 11 This is a structural diagram of a base provided in some embodiments of this application. The fourth sub-side plate 264 includes a connecting portion 2641 and a guiding portion 2642. The connecting portion 2641 is connected to the second sub-side plate 262, and the guiding portion 2642 is connected to the end of the connecting portion 2641 away from the second sub-side plate 262. The guiding portion 2642 is also connected to the first sub-side plate 261 (e.g., ...). Figure 4 (As shown) Connection. That is, the connection part 2641 is connected to the first sub-side plate 261 via the guide part 2642.

[0086] Based on this, see Figure 4 The surface of the guide portion 2642 near the first air outlet 211 is curved and recessed in a direction away from the first air outlet 211. This arrangement allows for a smooth transition between the fourth sub-side plate 264 and the first sub-side plate 261. This allows the gas, which has undergone preliminary mixing in the first premixing chamber 28, to flow more smoothly out of the first air outlet 211, resulting in a more stable airflow and promoting stable flame combustion.

[0087] For example, such as Figure 4 As shown, the curved surface is tangent to the surface of the first sub-side plate 261 near the first air outlet 211 at their junction, and the curved surface is also tangent to the surface of the connecting portion 2641 near the first air outlet 211 at their junction. This makes the transition between the fourth sub-side plate 264 and the first sub-side plate 261 smoother.

[0088] It is understandable that the surface of the guide portion 2642 near the first air outlet 211 can also be flat, and the end away from the connecting portion 2641 is inclined towards the first air outlet 211. In this way, the guide portion 2642 can also guide the airflow, facilitating the flow of gas in the first premixing chamber 28 out of the first air outlet 211. The specific choice can be made according to the actual situation, and this disclosure does not impose specific limitations on it.

[0089] In some embodiments, such as Figure 8 As shown, the burner head 1 is also provided with a second air inlet 17, and a first air inlet 16 is arranged circumferentially around the second air inlet 17, and the second air inlet 17 and the second mixing chamber 12 (as shown) Figure 2 (As shown) connected.

[0090] Based on this, see Figure 9 The base 2 also includes a connector 29, which passes through the first air outlet 211 and has a gap between itself and the inner surface of the first air outlet 211. In other words, the connector 29 does not completely block the first air outlet 211. As a result, the gas in the first premixing chamber 28 can flow out through the gap between the connector 29 and the inner surface of the first air outlet 211, and then flow normally into the first mixing chamber 11.

[0091] The connector 29 has a second premixing cavity 291 inside (e.g. Figure 2 As shown in the figure, a second air outlet 292 is provided on the surface away from the base plate 27, and the second air outlet 292 is connected to the second premixing chamber 291. The second air outlet 292 is connected to the second air inlet 17.

[0092] Based on this, a second mounting hole is provided on the side plate 26, and a second ejector tube 23 passes through the second mounting hole and is connected to the connector 29. The second ejector tube 23 communicates with the second premixing chamber 291.

[0093] In this case, the air and gas ejected by the second ejector tube 23 will first flow into the second premixing chamber 291 for preliminary mixing, then flow through the second air outlet 292 and the second air inlet 17 into the second mixing chamber 12 for further uniform mixing, and finally flow out through the second ignition hole 141 and be ignited.

[0094] This configuration allows for a more uniform mixing of primary air and fuel gas ejected by the second ejector tube 23, promoting more complete combustion of the fuel gas at the second ignition port 141. This reduces the risk of excessive carbon monoxide levels or the appearance of a yellow flame.

[0095] The connector 29 can be cylindrical or other regular or irregular shapes, and the specific shape can be selected according to the actual situation. This disclosure does not make any specific limitation in this regard.

[0096] It is understandable that the outer surface of the second ejector tube 23 is fitted to the inner surface of the second mounting hole. That is, there is no gap between the surfaces of the second ejector tube 23 and the second mounting hole that are close to each other, and the gas in the second premixing chamber 291 cannot leak out from the surfaces of the second ejector tube 23 and the second mounting hole that are close to each other.

[0097] Based on this, see Figure 2A gap can be provided between the connector 29 and the base plate 27, meaning that the two surfaces of the connector 29 and the base plate 27 that are close to each other do not contact each other, and the gas can flow between these two surfaces. This increases the volume of the first premixing chamber 28, which helps to make the primary air and fuel gas mixed more evenly in the first premixing chamber 28.

[0098] It should be noted that if the first mounting hole is located on the first sub-side plate 261, the second mounting hole can also be located on the first sub-side plate 261. This facilitates the side-by-side arrangement of the first ejector tube 22 and the second ejector tube 23. This not only reduces the space occupied by the first ejector tube 22 and the second ejector tube 23, making the structure of the base 2 more compact, but also facilitates the layout of the gas pipeline and reduces the risk of pipeline crossing.

[0099] In some embodiments, see Figure 9 The base 2 also includes an annular protrusion 3. The annular protrusion 3 is located on the top plate 21 near the burner head 1 (e.g., Figure 2 The base 2 is located on one side of the first gas outlet 211 and is arranged around the periphery of the first gas outlet 211. The annular protrusion 3 is connected to the burner head 1, so that the base 2 can better support the burner head 1, which helps to improve the reliability of the burner head 1 installation.

[0100] The annular protrusion 3 can be seen as an extension of the first air outlet 211 toward the burner head 1. This arrangement facilitates the connection between the first air outlet 211 and the first air inlet 16.

[0101] In this case, the connector 29 can be configured as a column and coaxially arranged with the annular protrusion 3. In this way, it is only necessary to arrange the first air inlet 16 around the second air inlet 17 and to arrange the first air inlet 16 and the second air inlet 17 coaxially to easily achieve the connection between the first air inlet 16 and the first air outlet 211, and the connection between the second air inlet 17 and the second air outlet 292.

[0102] This not only simplifies the structure of the burner 15 and the flame cap, thus reducing the design difficulty of the burner head 1, but also makes it easier to match the base 2 with the universal burner 15 and flame cap, thereby improving the versatility of the base 2.

[0103] It should be noted that the first air inlet 16 can be connected to the first mixing chamber 11 through multiple coaxially arranged channels. This will make the air pressure in the first mixing chamber 11 more balanced, which is conducive to stable combustion of the flame.

[0104] In some embodiments, such as Figure 9 As shown, the top plate 21 is also equipped with a first air intake 212, see [reference]. Figure 12 , Figure 12This is a structural diagram of a base provided for some embodiments of this application. The base 2 also includes a first windbreak 41 (e.g., Figure 6 (as shown) and the first cover plate 42. The first baffle plate 41 is disposed on the side of the top plate 21 away from the furnace head 1 and is connected to the top plate 21.

[0105] Among them, see Figure 13 , Figure 13 This is a structural diagram of the base provided in some embodiments of this application. A first baffle plate 41 is arranged circumferentially around the first air intake 212. A first cover plate 42 is connected to the first baffle plate 41 and together with the first baffle plate 41 and the top plate 21, forms a first ejector cavity 4. The two ends of the first ejector tube 22 and the first nozzle 24 that are close to each other are located inside the first ejector cavity 4.

[0106] In this configuration, when the first nozzle 24 injects gas into the first ejector tube 22, the high-speed airflow reduces the gas pressure inside the first ejector chamber 4, creating a negative pressure within it. This allows air from the side of the top plate 21 closest to the burner 1 to flow into the first ejector chamber 4 through the first air intake 212 under atmospheric pressure, thus replenishing the primary air supply. This design facilitates the entry of primary air from above the countertop into the fully top-intake gas stove 100, eliminating the need for ventilation holes in the cabinet.

[0107] It is understood that the first windbreak plate 41 and the first cover plate 42 can be integrally formed with the top plate 21, or they can be three independent components connected as a whole by welding, bonding or other methods. The specific choice can be made according to the actual situation, and this disclosure does not make any specific limitations.

[0108] For example, such as Figure 11 As shown, the first baffle plate 41 and the first cover plate 42 are integrally formed with the top plate 21. This arrangement helps to improve the airtightness of the first ejector cavity 4, thereby improving the ejection effect and ensuring a more sufficient supply of primary air for complete combustion of the fuel gas.

[0109] Based on this, see Figure 13 The base 2 may also include a first baffle 43, which is disposed on the side of the top plate 21 near the burner head 1 and connected to the top plate 21. The first baffle 43 is arranged around the first air intake 212.

[0110] In this configuration, the first baffle 43 can block liquid dripping onto the top plate 21 during cooking, thereby reducing the risk of liquid entering the first ejector chamber 4 through the first air intake 212 and causing blockage of the first nozzle 24. This reduces the risk of gas leakage, thus improving the safety of the fully top-intake gas stove 100.

[0111] It is understandable that the first baffle 43 can also be integrally formed with the top plate 21.

[0112] For example, such as Figure 14 As shown, Figure 14 This is a structural diagram of a fully top-intake gas stove provided in some embodiments of this application. The end of the first baffle 43 furthest from the top plate 21 abuts against the burner head 1, and the first baffle 43 is provided with a first air intake opening 431, located at the end of the first baffle 43 furthest from the top plate 21. In this way, the first baffle 43 can provide support for the burner head 1, thereby improving the reliability of the burner head 1 installation.

[0113] At this time, when the fully top-intake gas stove 100 is working, air can flow into the first ejector chamber 4 through the first air intake opening 431 and the first air intake 212 in sequence, thereby replenishing the air.

[0114] The first air inlet 431 can be located on the side of the first baffle 43 away from the first air outlet 211. This reduces the obstruction of air by the burner head 1 and facilitates the replenishment of primary air.

[0115] In some embodiments, such as Figure 9 As shown, a second air intake 213 is provided on the top plate 21. (See attached image) Figure 12 The base 2 also includes a second wind deflector 44 (such as...) Figure 6 (as shown) and the second cover plate 45. The second baffle plate 44 is disposed on the side of the top plate 21 away from the furnace head 1 and is connected to the top plate 21.

[0116] Among them, see Figure 13 The second baffle plate 44 is arranged circumferentially around the second air intake 213. The second cover plate 45 is connected to the second baffle plate 44 and together with the second baffle plate 44 and the top plate 21, forms the second ejector cavity 5. The two ends of the second ejector tube 23 and the second nozzle 25, which are close to each other, are located inside the second ejector cavity 5.

[0117] With this configuration, when the second nozzle 25 injects gas into the second injector tube 23, the high-speed airflow reduces the gas pressure inside the second injector chamber 5, creating a negative pressure within it. This allows air from the side of the top plate 21 closest to the burner 1 to flow into the second injector chamber 5 through the second air intake 213 under atmospheric pressure, thus replenishing the primary air supply. This facilitates the entry of primary air from above the countertop into the fully top-intake gas stove 100, eliminating the need for ventilation holes in the cabinet.

[0118] It should be noted that the first wind deflector 41 and the second wind deflector 44 can partially overlap.

[0119] It is understood that the second wind deflector 44 and the second cover plate 45 can be integrally formed with the top plate 21, or they can be three independent components connected as a whole by welding, bonding, or other methods. The specific choice can be made according to the actual situation, and this disclosure does not impose any specific limitations on this.

[0120] For example, such as Figure 11 As shown, the second baffle plate 44 and the second cover plate 45 are integrally formed with the top plate 21. This arrangement helps to improve the airtightness of the second ejector cavity 5, thereby improving the ejection effect and ensuring a more sufficient supply of primary air for complete combustion of the fuel gas.

[0121] Based on this, see Figure 13 The base 2 may also include a second baffle 46, which is disposed on the side of the top plate 21 near the burner head 1 and connected to the top plate 21. The second baffle 46 is arranged around the second air intake 213.

[0122] In this configuration, the second baffle 46 can block liquid dripping onto the top plate 21 during cooking, thereby reducing the risk of liquid entering the second ejector chamber 5 through the second air intake 213 and causing blockage of the second nozzle 25. This reduces the risk of gas leakage, thus improving the safety of the fully top-intake gas stove 100.

[0123] It should be noted that the first baffle 43 and the second baffle 46 can partially overlap.

[0124] Understandably, the second baffle 46 can also be integrally formed with the top plate 21.

[0125] For example, such as Figure 14 As shown, the end of the second baffle 46 away from the top plate 21 abuts against the base 2, and the second baffle 46 is provided with a second air inlet 461, which is located at the end of the second baffle 46 away from the top plate 21. In this way, the second baffle 46 can provide support for the burner head 1, thereby improving the reliability of the burner head 1 installation.

[0126] At this time, when the fully top-intake gas stove 100 is working, air can flow into the second ejector chamber 5 through the second air intake opening 461 and the second air intake 213 in sequence, thereby replenishing the air.

[0127] The second air inlet 461 can be located on the side of the second baffle 46 away from the first air outlet 211. This reduces the obstruction of air by the burner head 1 and facilitates the replenishment of primary air.

[0129] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto.
