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 gaseous fuels such as liquefied petroleum gas, manufactured gas, and natural gas 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.

[0003] Among them, fully top-intake gas stoves draw both primary and secondary air from above the cooktop, eliminating the need for ventilation holes in cabinets and 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 offering higher safety. However, these fully top-intake gas stoves tend to have lower flame strength. Summary of the Invention

[0004] This application provides a fully top-intake gas stove that can improve the firepower of a fully top-intake gas stove.

[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 first injector tube, a first burner cap, and a first flame distributor.

[0007] The first flame cap has a first flame outlet, and the first flame distributor is located on one side of the first flame cap and connected to it. The first flame distributor and the first flame cap form a first mixing chamber, and the first ejector tube communicates with the first mixing chamber. The first mixing chamber has a guide protrusion, which is used to guide the airflow ejected by the first ejector tube to the first flame outlet.

[0008] The fully top-intake gas stove provided in this embodiment has a guide protrusion in its first mixing chamber, which directs the airflow from the first injector tube to the first flame outlet. This arrangement allows the gas and primary air injected into the first mixing chamber by the guide protrusion to flow more smoothly to the first flame outlet. Consequently, more gas and primary air can flow out of the first flame outlet per unit time and be ignited to form a flame. This improves the firepower of the fully top-intake gas stove.

[0009] In some embodiments, the first ignition distributor includes a first annular side plate, a second annular side plate, and a connecting plate. The first annular side plate is connected to a first flame cap. A first air inlet is provided on the first annular side plate, and one end of a first ejector tube is connected to the first air inlet. The second annular side plate is disposed around the periphery of the first annular side plate and is connected to the first flame cap. The connecting plate is connected to the first and second annular side plates and, together with the first annular side plate, the second annular side plate, and the first flame cap, forms a first mixing chamber. A guide protrusion is disposed on the connecting plate and is offset from the first air inlet.

[0010] In some embodiments, the center of the first air inlet is located on the side of the surface of the guide protrusion away from the connecting plate, close to the connecting plate.

[0011] In some embodiments, the flow guide protrusion extends circumferentially along the first annular side plate, wherein the end faces of the flow guide protrusion at both ends in the extension direction are inclined surfaces.

[0012] In some embodiments, the guide protrusion includes a top wall, a first side wall, and a second side wall. The top wall is disposed opposite to the connecting plate and extends circumferentially along the first annular side plate. The top wall is connected to the first annular side plate and the second annular side plate. The first side wall is disposed between the top wall and the connecting plate and is located on one side of the top wall in the extending direction of the top wall. The first side wall is connected to the top wall, the first annular side plate, the second annular side plate, and the connecting plate, and the first side wall is inclined. The second side wall is disposed between the top wall and the connecting plate and is located on the other side of the top wall in the extending direction of the top wall. The second side wall is connected to the top wall, the first annular side plate, the second annular side plate, and the connecting plate, and the second side wall is inclined.

[0013] In some embodiments, the first annular side plate is provided with a plurality of first air inlets, which divide the first mixing chamber into multiple segments. Each segment of the first mixing chamber is provided with a guide protrusion. The fully top-intake gas stove includes a plurality of first ejector tubes, each first ejector tube corresponding to a first air inlet and connected to the corresponding first air inlet.

[0014] In some embodiments, the fully top-intake gas stove further includes a base and a gas collection hood. The base includes a top plate and a first nozzle. The top plate is disposed on the side of the first burner away from the first burner cap and is connected to the first burner. The first nozzle is disposed on the side of the top plate near the first burner and is connected to the top plate. The first nozzle is coaxially arranged with a first ejector tube. The gas collection hood is disposed on the side of the top plate near the first burner and is connected to the first ejector tube. The gas collection hood and the base form an ejector cavity with an air intake channel, and the end of the first ejector tube away from the first mixing chamber and the first nozzle are located within the ejector cavity.

[0015] In some embodiments, the top plate has an annular protrusion on the side near the gas collecting hood, and the annular protrusion surrounds the periphery of the first nozzle. The end of the first ejector tube away from the first mixing chamber is located inside the annular protrusion. In a first direction, the annular protrusion partially overlaps with the gas collecting hood, and the overlapping portion of the annular protrusion and the gas collecting hood forms an air intake channel. The first direction is parallel to the surface of the top plate near the first flame distributor.

[0016] In some embodiments, the angle between the axis of the first nozzle and the surface of the top plate near the first fire distributor is greater than or equal to 5° and less than or equal to 20°.

[0017] In some embodiments, the base further includes a second nozzle disposed within the injection chamber and connected to the top plate. The fully top-intake gas stove also includes a second burner cap, a second flame distributor, and a second injection tube. The second burner cap is disposed on the side of the gas collecting hood away from the top plate, and has a second flame outlet. The second flame distributor is disposed between the second burner cap and the gas collecting hood, and is connected to the second burner cap. The second flame distributor and the second burner cap form a second mixing chamber, and the second injection tube communicates with the second mixing chamber, with one end of the tube away from the second mixing chamber located within the injection chamber. The second injection tube is connected to the second flame distributor and the gas collecting hood. The second nozzle is coaxially arranged with the second injection tube.

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 "exemplarily" 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 a burner head and an injector tube. The burner head has a mixing chamber and a flame outlet communicating with the mixing chamber. The injector tube communicates with the mixing chamber and is used to inject gas and primary air into it. When heating cookware using this fully top-intake gas stove, the gas and primary air injected by the injector tube must completely fill the mixing chamber before flowing out from the flame outlet, resulting in a low rate of gas and primary air flow. This leads to lower heat output from the fully top-intake gas stove, making it unsuitable for high-heat cooking and resulting in a poor user experience.

[0044] Based on this, such as Figure 1 As shown, Figure 1This is an exploded view of a fully top-intake gas stove provided in some embodiments of this application. Embodiments of this application provide a fully top-intake gas stove 100, which can improve the firepower of the fully top-intake gas stove 100. The fully top-intake gas stove 100 includes a first burner cap 1 and a first flame distributor 2.

[0045] See Figure 2 , Figure 2 This is a cross-sectional view of a fully top-intake gas stove provided in some embodiments of this application. The first burner 2 is disposed on one side of the first burner cap 1 and connected to the first burner cap 1, forming a first mixing chamber 11 with the first burner cap 1.

[0046] It is understood that there are multiple ways to connect the first flame distributor 2 and the first flame cap 1. For example, the first flame distributor 2 and the first flame cap 1 can be connected together by welding, snap-fit ​​connection, or abutment. The specific method can be selected according to the actual situation, and this application does not make any specific limitation.

[0047] For example, such as Figure 2 As shown, the first ignition distributor 2 and the first flame cap 1 are connected by an abutment, meaning that the first flame cap 1 is placed on the first ignition distributor 2 and can be directly removed from it. This arrangement facilitates the removal of the first flame cap 1 from the first ignition distributor 2 for cleaning the first mixing chamber 11.

[0048] Among them, such as Figure 1 As shown, the first flame cap 1 is provided with a first flame outlet 12, which can be understood to be connected to the first mixing chamber 11. Based on this, see... Figure 3 , Figure 3 This application provides structural diagrams of a first flame distributor and a first injector tube according to some embodiments. The fully top-intake gas stove 100 may further include a first injector tube 3, the first injector tube 3 and the first mixing chamber 11 (e.g., Figure 2 (As shown) connected.

[0049] In this way, the gas and primary air ejected by the first ejector tube 3 can flow into the first mixing chamber 11 through the first ejector tube 3, and after being mixed evenly, they can flow out through the first ignition hole 12 connected to the first mixing chamber 11, and then be ignited to form a flame.

[0050] For example, such as Figure 4 As shown, Figure 4 This is a structural diagram of a first flame spreader provided in some embodiments of this application. The first flame spreader 1 includes a first cover plate 13, a first connecting plate 2314, and a second connecting plate 2315. The first cover plate 13 is provided with a clearance hole 131, and the first connecting plate 2314 and the second connecting plate 2315 are disposed on the first cover plate 13 near the first flame distributor 2 (e.g., Figure 2As shown, both are located on one side and are connected to the first cover plate 13 and the first flame distributor 2. The first connecting plate 2314 is arranged around the periphery of the clearance hole 131, and the second connecting plate 2315 is arranged around the periphery of the first connecting plate 2314. The first flame outlet 12 is provided on the second connecting plate 2315.

[0051] It is understood that the second connecting plate 2315 is typically provided with a plurality of first flame outlet holes 12, which are arranged at intervals along the circumference of the second connecting plate 2315. The plurality of first flame outlet holes 12 may include a plurality of first sub-flame outlet holes 121 and a plurality of second sub-flame outlet holes 122, with the plurality of first sub-flame outlet holes 121 located on the side of the plurality of second sub-flame outlet holes 122 near the first cover plate 13.

[0052] This configuration allows for more even heating of the cooktop when using a fully top-draft gas stove 100, thus improving cooking results.

[0053] The second connecting plate 2315, on the side furthest from the first connecting plate 2314, may also be provided with a first flame groove 151. The first flame groove 151 extends circumferentially along the second connecting plate 2315 and surrounds the periphery of the first connecting plate 2314. The first flame groove 151 communicates with the aforementioned plurality of second sub-flame holes 122. In this way, when the fully top-intake gas stove 100 is operating, the flame distribution is more uniform, thereby further improving the cooking effect.

[0054] The first flame groove 151 has a dimension greater than 0.5 mm and less than 1.0 mm in the extension direction of the clearance hole 131. The specific dimension can be selected according to actual conditions, and this application does not impose specific limitations on it. For example, the second flame groove 641 has a dimension of 0.8 mm in the axial direction of the annular connecting plate 64.

[0055] It should be noted that the first ejector tube 3 and the first fire distributor 2 can be integrally formed, or they can be two independent components connected as a whole by welding, screw connection, snap-fit ​​connection, interference fit, etc. The specific choice can be made according to the actual situation, and this disclosure does not make specific limitations.

[0056] For example, such as Figure 3 As shown, the first injector tube 3 and the first flame distributor 2 are integrally formed. With this configuration, when assembling the fully top-intake gas stove 100, the first injector tube 3 and the first flame distributor 2 can be assembled together as a single part with other parts. This reduces the need to adjust the relative positional relationship between the first injector tube 3 and the first flame distributor 2, thereby reducing the assembly difficulty of the fully top-intake gas stove 100 and improving the assembly efficiency of the fully top-intake gas stove 100.

[0057] Based on this, see Figure 2 The first mixing chamber 11 is provided with a flow guiding protrusion 111, which is used to guide the airflow injected by the first ejector tube 3 to the first flame outlet 12.

[0058] The fully top-intake gas stove 100 provided in this embodiment has a guide protrusion 111 in its first mixing chamber 11, which guides the airflow from the first injector tube 3 to the first flame outlet 12. In this configuration, guided by the guide protrusion 111, the gas and primary air injected into the first mixing chamber 11 by the first injector tube 3 can flow more smoothly to the first flame outlet 12. This allows more gas and primary air to flow out of the first flame outlet 12 per unit time, where they are then ignited to form a flame. Thus, the firepower of the fully top-intake gas stove 100 is increased.

[0059] In some embodiments, such as Figure 2 As shown, the first flame spreader 2 includes a first annular side plate 21 and a second annular side plate 22. The first annular side plate 21 is connected to the first flame cap 1, and the second annular side plate 22 is arranged around the periphery of the first annular side plate 21 and is connected to the first flame cap 1. It should be noted that when the first flame cap 1 includes a first connecting plate 2314 and a second connecting plate 2315, the first annular side plate 21 is connected to the first connecting plate 2314, and the second annular side plate 22 is connected to the second connecting plate 2315.

[0060] It is understandable that when the first flame distributor 2 and the first flame cap 1 are connected by abutting, both the first annular side plate 21 and the second annular side plate 22 abut against the first flame cap 1.

[0061] Based on this, see Figure 2 The first flame divider 2 also includes a connecting plate 23, which is connected to the first annular side plate 21 and the second annular side plate 22, and together with the first annular side plate 21, the second annular side plate 22 and the first flame cap 1, forms a first mixing chamber 11.

[0062] For example, such as Figure 2 As shown, the connecting plate 23 is integrally formed with the first annular side plate 21 and the second annular side plate 22. This not only improves the structural strength of the flame distributor, but also improves the airtightness of the first mixing chamber 11, which helps to reduce the risk of gas leakage and thus improves the safety performance of the fully top-intake gas stove 100.

[0063] It is understood that the connecting plate 23 can be disposed on the side of the first annular side plate 21 and the second annular side plate 22 away from the first flame cap 1, with one end connected to the end of the first annular side plate 21 away from the first flame cap 1 and the other end connected to the end of the second annular side plate 22 away from the first flame cap 1. That is to say, the first annular side plate 21, the second annular side plate 22 and the connecting plate 23 form an open cavity with a U-shaped cross-section.

[0064] This configuration increases the volume of the first mixing chamber 11, allowing for a more uniform mixing of the fuel gas and primary air within it. This, in turn, promotes complete combustion of the fuel gas at the first ignition port 12, thereby reducing the risk of excessive carbon monoxide levels or the appearance of a yellow flame.

[0065] It should be noted that the connecting plate 23 can be a flat plate, an arc-shaped plate, or a plate of other shapes. The specific type can be selected according to the actual situation, and this application does not impose any specific limitations on it. In addition, the first annular side plate 21 and the second annular side plate 22 can be arranged coaxially, or the axes of the first annular side plate 21 and the second annular side plate 22 can be staggered. The specific type can be selected according to the actual situation, and this application does not impose any specific limitations on it.

[0066] For example, such as Figure 3 As shown, the first annular side plate 21 and the second annular side plate 22 are coaxially arranged. In this way, the first mixing chamber 11 (as shown) can be made more coaxial. Figure 2 As shown, the radial dimensions are kept consistent, which helps to ensure a more even flame distribution from the fully top-intake gas stove 100. This results in more even heating of cookware when using the fully top-intake gas stove 100, thus improving cooking performance.

[0067] like Figure 2 As shown, when the first distributor 2 includes a first annular side plate 21, a second annular side plate 22, and a connecting plate 23, a first air inlet 211 can be provided on the first annular side plate 21, and the first air inlet 211 communicates with the first mixing chamber 11. Based on this, participants... Figure 3 One end of the first ejector tube 3 is connected to the first air inlet 211. In this way, the first ejector tube 3 can be connected to the first mixing chamber 11. At this time, the fuel gas and primary air ejected by the first ejector tube 3 can flow into the first mixing chamber 11 through the first air inlet 211.

[0068] Understandably, multiple first air inlets 211 can be provided on the first annular side plate 21, dividing the first mixing chamber 11 into multiple segments. Each segment of the first mixing chamber 11 is provided with a guide protrusion 111. At this time, the fully top-intake gas stove 100 includes multiple first ejector tubes 3, each first ejector tube 3 corresponding to a first air inlet 211 and connected to the corresponding first air inlet 211.

[0069] For example, such as Figure 3 As shown, the first annular side plate 21 is provided with two first air inlets 211. The fully top-inlet gas stove 100 includes two first ejector pipes 3, each of which is connected to a first air inlet 211.

[0070] In this configuration, multiple first ejector tubes 3 can simultaneously deliver gas and primary air to the first mixing chamber 11. This increases the replenishment rate of gas and primary air in the first mixing chamber 11, thereby increasing the rate at which gas and primary air flow out through the first flame outlet 12, and thus improving the firepower of the fully top-intake gas stove 100.

[0071] Among them, such as Figure 2 As shown, the center of the first air inlet 211 can be positioned on the side of the guide protrusion 111 away from the connecting plate 23, close to the connecting plate 23. This arrangement increases the distance between the first air inlet 211 and the first flame outlet 12, reducing the risk of insufficient mixing of the gas and primary air flowing into the first mixing chamber 11 through the first air inlet 211, thus allowing the gas to burn more completely at the first flame outlet 12. Furthermore, it allows the guide protrusion 111 to have a better guiding effect, ensuring smoother flow of the airflow from the first ejector tube 3 to the first flame outlet 12, thereby increasing the firepower of the fully top-intake gas stove 100.

[0072] It should be noted that the guide protrusion 111 can be set on the connecting plate 23 and offset from the first air inlet 211. In this way, the obstruction of the airflow induced by the guide protrusion 111 on the airflow induced by the first ejector tube 3 can be reduced, which is conducive to the airflow flowing more smoothly to the first flame outlet 12. Thus, the firepower of the fully top-intake gas stove 100 can be further improved.

[0073] At this time, as Figure 3 As shown, the flow guiding protrusion 111 can be configured to extend circumferentially along the first annular side plate 21, and the end faces of the flow guiding protrusion 111 at both ends in the extension direction are inclined surfaces.

[0074] It is understandable that the end faces of the guide protrusion 111, which are furthest from the connecting plate 23 in the extending direction, are inclined towards the center of the guide protrusion 111 in the extending direction. In this way, the airflow ejected by the first ejector tube 3 can flow towards the first flame cap 1 (e.g., under the guidance of the aforementioned inclined surface) under the direction of the inclined surface. Figure 2 (as shown), and then flows out through the first flame outlet 12 on the first flame cap 1.

[0075] For example, such as Figure 3 As shown, the guide protrusion 111 includes a top wall 1111, a first side wall 1112, and a second side wall 1113. The top wall 1111 is disposed opposite to the connecting plate 23 and extends circumferentially along the first annular side plate 21, and is connected to the first annular side plate 21 and the second annular side plate 22. It should be noted that the top wall 1111 and the first flame cap 1 (e.g., Figure 2 There can be a gap between the two (as shown), so that the first flame outlet 12 can also be set at the position corresponding to the first burner cap 1 and the top wall 1111. With this arrangement, when heating the cookware using the fully top-intake gas stove 100, the cookware can be heated more evenly.

[0076] Based on this, the first sidewall 1112 and the second sidewall 1113 are disposed between the top wall 1111 and the connecting plate 23, with the first sidewall 1112 located on one side of the top wall 1111 in its extending direction, and the second sidewall 1113 located on the other side of the top wall 1111 in its extending direction. That is, in the extending direction of the top wall 1111, the first sidewall 1112 and the second sidewall 1113 are respectively disposed on both sides of the top wall 1111. Both the first sidewall 1112 and the second sidewall 1113 are connected to the top wall 1111, the first annular side plate 21, the second annular side plate 22, and the connecting plate 23, and both the first sidewall 1112 and the second sidewall 1113 are inclined. In this way, the first sidewall 1112, the second sidewall 1113, and the top wall 1111 can form a flow-guiding protrusion 111, and this structure is simple and easy to implement.

[0077] It should be noted that the end of the first sidewall 1112 away from the connecting plate 23 is inclined towards the center of the top wall 1111 in the extending direction of the top wall 1111. Similarly, the end of the second sidewall 1113 away from the connecting plate 23 is inclined towards the center of the top wall 1111 in the extending direction of the top wall 1111.

[0078] It is understood that the guide protrusion 111 may also include only the inclined first sidewall 1112 and the second sidewall 1113, which are connected to each other and are both connected to the connecting plate 23, the first annular side plate 21, and the second annular side plate 22. The specific choice can be made according to the actual situation, and this application does not make any specific limitation.

[0079] In some embodiments, such as Figure 5 As shown, Figure 5 This is a structural diagram of the base provided for some embodiments of this application. The fully top-intake gas stove 100 also includes a base 4, which includes a top plate 41 and a first nozzle 42. See also Figure 6 , Figure 6 This is a cross-sectional view of a fully top-intake gas stove provided in some embodiments of this application. A top plate 41 is disposed on the side of the first burner 2 away from the first burner cap 1 and is connected to the first burner 2. A first nozzle 42 is disposed on the side of the top plate 41 near the first burner 2 and is connected to the top plate 41. The position of the first nozzle 42 corresponds to that of the first ejector tube 3.

[0080] It should be noted that the correspondence between the positions of the first nozzle 42 and the first ejector tube 3 means that the first nozzle 42 is located within the opening range of the first ejector tube 3. In this way, the gas ejected from the first nozzle 42 can directly enter the first ejector tube 3.

[0081] In this situation, when the first nozzle 42 injects the gas into the first ejector tube 3, the air near the opening of the first ejector tube 3 will be ejected into the first ejector tube 3 along with the gas. This part of the air will be used as primary air and flow into the first mixing chamber 11 through the first ejector tube 3 along with the gas. After being mixed evenly, it will flow out through the first ignition hole 12 connected to the first mixing chamber 11 and then be ignited to form a flame.

[0082] The first nozzle 42 can be coaxially arranged with the first ejector tube 3. In this way, when the first nozzle 42 injects gas into the first ejector tube 3, the risk of gas leakage is reduced, while the ability of the first ejector tube 3 to eject primary air is improved, thereby improving the safety and combustion performance of the fully top-intake gas stove 100.

[0083] Based on this, such as Figure 6As shown, the angle α between the axis of the first nozzle 42 and the surface of the top plate 41 near the first burner 2 can be set to be greater than or equal to 5° and less than or equal to 20°. This configuration not only allows the airflow entering the first mixing chamber 11 to tend to flow towards the first flame outlet 12, thereby increasing the rate at which gas and primary air flow out of the first flame outlet 12 and thus improving the firepower of the fully top-intake gas stove 100, but also reduces the risk of insufficient mixing of gas and primary air, i.e., the gas flowing out through the first flame outlet 12.

[0084] For example, such as Figure 6 As shown, the angle α between the axis of the first nozzle 42 and the surface of the top plate 41 near the first fire distributor 2 can be set to any one of 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, and 20°. The specific angle can be selected according to the actual situation, and this application does not impose any specific limitation. For example, the angle α between the axis of the first nozzle 42 and the surface of the top plate 41 near the first fire distributor 2 is 12°.

[0085] It is understandable that in the case of a fully top-intake gas stove 100 including multiple first ejector tubes 3, the base 4 includes multiple first nozzles 42, each first nozzle 42 corresponding to a first ejector tube 3.

[0086] Based on this, see Figure 7 , Figure 7 This is a structural diagram of the first flame distributor, first injector tube, base, and gas collection hood provided in some embodiments of this application. The fully top-intake gas stove 100 also includes a gas collection hood 5, which is disposed on the top plate 41 near the first flame distributor 2 and connected to the first injector tube 3. The gas collection hood 5 and the base 4 form an injector cavity 51 with an air intake channel 52 (e.g., ...). Figure 6 As shown), the first ejector tube 3 is far from the first mixing chamber 11 (as shown). Figure 6 One end of the nozzle 42 (as shown) and the first nozzle 42 are located inside the ejector cavity 51.

[0087] At this time, when the first nozzle 42 injects gas into the first ejector tube 3, the high-speed airflow can reduce the gas pressure in the ejector cavity 51, thereby creating a negative pressure in the ejector cavity 51. In this way, the air on the side of the top plate 41 near the first flame distributor 2 can flow into the ejector cavity 51 through the air intake channel 52 under the action of atmospheric pressure, so as to achieve primary air replenishment.

[0088] With this configuration, when the first nozzle 42 injects gas into the first ejector tube 3, the gas collection hood 5 can reduce the risk of gas leakage, thereby improving the safety performance of the fully top-intake gas stove 100.

[0089] It should be noted that the gas collecting hood 5 and the first ejector tube 3 can be integrally formed, or they can be two independent components connected as a whole by welding, screw connection, snap-fit ​​connection, interference fit, etc. The specific choice can be made according to the actual situation, and this disclosure does not make specific limitations.

[0090] For example, the gas hood 5 and the first ejector tube 3 are integrally formed. This arrangement helps to improve the structural strength of the fully top-intake gas stove 100, extend its service life, and improve the user experience. At the same time, it can also reduce the assembly difficulty of the fully top-intake gas stove 100 and improve its assembly efficiency.

[0091] It is understandable that, such as Figure 8 As shown, Figure 8 This is a cross-sectional view of a fully top-intake gas stove provided in some embodiments of this application. The base 4 may further include a second nozzle 43, which is disposed within the ejector cavity 51 and connected to the top plate 41. In this case, the fully top-intake gas stove 100 also includes a second burner cap 6, a second flame distributor 7, and a second ejector tube 8. The second burner cap 6 is disposed on the side of the gas collecting hood 5 away from the top plate 41, and the second burner cap 6 has a second flame outlet 61. The second flame distributor 7 is disposed between the second burner cap 6 and the gas collecting hood 5, and is connected to the second burner cap 6. The second flame distributor 7 and the second burner cap 6 form a second mixing chamber 62, and the second ejector tube 8 communicates with the second mixing chamber 62, with one end away from the second mixing chamber 62 located within the ejector cavity 51. The second ejector tube 8 is connected to the second flame distributor 7 and the gas collecting hood 5. The second nozzle 43 is coaxially arranged with the second ejector tube 8.

[0092] In this configuration, the air in the ejector chamber 51, along with the gas ejected from the second nozzle 43, is drawn into the second mixing chamber 62 by the second ejector tube 8, flows out through the second flame outlet 61, and is then ignited to form a flame. This further increases the firepower of the fully top-intake gas stove 100.

[0093] For example, such as Figure 8 As shown, the axis of the second ejector tube 8 is perpendicular to the surface of the top plate 41 near the gas collection hood 5.

[0094] It should be noted that, in the case of the fully top-intake gas stove 100 including the first burner 2, the first injector tube 3, the second burner 7, the second injector tube 8, and the gas collection hood 5, the first burner 2, the first injector tube 3, the second burner 7, the second injector tube 8, and the gas collection hood 5 can be integrally formed. This helps to improve the structural strength of the fully top-intake gas stove 100, while reducing the assembly difficulty and increasing the assembly efficiency of the fully top-intake gas stove 100.

[0095] Among them, see Figure 9 , Figure 9 This is a structural diagram of a second flame spreader provided in some embodiments of this application. The second flame spreader 6 may include a second cover plate 63 and an annular connecting plate 64. The annular connecting plate 64 is disposed on the second cover plate 63 near the second flame distributor 7 (e.g., Figure 8 (As shown) on one side, and connected to the second cover plate 63 and the second flame distributor 7. The second flame outlet 61 is provided on the annular connecting plate 64.

[0096] It is understandable that the annular connecting plate 64 typically has multiple second flame outlet holes 61, which are arranged at intervals along the circumference of the annular connecting plate 64. For example... Figure 10 As shown, Figure 10 This is a structural diagram of the second flame cover provided in some embodiments of this application. The plurality of second flame outlets 61 may include a plurality of third sub-flame outlets 611 and a plurality of fourth sub-flame outlets 612. The plurality of third sub-flame outlets 611 are disposed on the side of the plurality of fourth sub-flame outlets 612 near the second cover plate 63, and a fourth sub-flame outlet 612 is provided between every two adjacent third sub-flame outlets 611.

[0097] This configuration allows for more even heating of the cooktop when using a fully top-draft gas stove 100, which further improves cooking results.

[0098] For example, such as Figure 10 As shown, a second flame groove 641 is formed between the annular connecting plate 64 and the second cover plate 63, and the second flame groove 641 and the second mixing chamber 62 (as shown) Figure 8 (As shown) It is connected and extends circumferentially along the annular connecting plate 64. By setting the second flame groove 641, the flame distribution can be more uniform when the fully top-intake gas stove 100 is working, thereby further improving the cooking effect.

[0099] The second flame groove 641 has an axial dimension greater than 0.5 mm and less than 1.0 mm in the annular connecting plate 64. The specific dimension can be selected based on actual conditions, and this application does not impose specific limitations. For example, the axial dimension of the second flame groove 641 in the annular connecting plate 64 may be 0.7 mm.

[0100] In some embodiments, such as Figure 11 As shown, Figure 11 This is a structural diagram of a first ejector, a first ejector tube, a base, and a gas collecting hood provided in some embodiments of this application. An annular protrusion 411 is provided on the side of the top plate 41 near the gas collecting hood 5, and the annular protrusion 411 surrounds the periphery of the first nozzle 42. The first ejector tube 3 (e.g.) Figure 6 As shown) away from the first mixing chamber 11 (as shown) Figure 6One end of the [symbol shown] is located inside the annular protrusion 411. See [reference]. Figure 6 In the first direction X, the annular protrusion 411 partially overlaps with the gas collecting hood 5. That is, the end face of the gas collecting hood 5 near the top plate 41 is flush with the end face of the annular protrusion 411 away from the top plate 41, or the end face of the gas collecting hood 5 near the top plate 41 is located on the side of the end face of the annular protrusion 411 away from the top plate 41 closest to the top plate 41. The overlapping portion of the annular protrusion 411 and the gas collecting hood 5 forms an air intake channel 52. The first direction X is parallel to the surface of the top plate 41 near the first flame distributor 2.

[0101] The annular protrusion 411 can restrict the diffusion of gas to the periphery of the fully upward-intake gas stove 100, thereby reducing the risk of gas leakage and improving the safety performance of the fully upward-intake gas stove 100. In addition, the annular protrusion 411 can also block liquid dripping onto the top plate 41 during cooking, thereby reducing the risk of liquid entering the ejector chamber 51 through the air intake channel 52 and causing blockage of the first nozzle 42.

[0102] It should be noted that the annular protrusion 411 can be arranged either around the gas collecting hood 5 or inside the gas collecting hood 5; the choice can be made according to the actual situation, and this application does not impose a specific limitation on this. For example, as shown... Figure 6 As shown, the annular protrusion 411 is located on the inner side of the gas collection hood 5.

[0103] It is understandable that, such as Figure 12 As shown, Figure 12 This is a structural diagram of the base provided for some embodiments of this application. The base 4 may also include a first air inlet pipe 44 and a second air inlet pipe 45, both of which are disposed on the top plate 41 away from the first flame distributor 2 (e.g., Figure 11 (As shown) on one side, and connected to the top plate 41. See also... Figure 11 The first air intake pipe 44 is connected to the first nozzle 42 and is used to supply gas to the first nozzle 42; the second air intake pipe 45 is connected to the second nozzle 43 and is used to supply gas to the second nozzle 43.

[0104] Based on this, the axes of the first air intake pipe 44 and the second air intake pipe 45 are both parallel to the surface of the top plate 41 away from the first flame distributor 2, and the distance between the axis of the first air intake pipe 44 and the top plate 41 is greater than or less than the distance between the axis of the second air intake pipe 45 and the top plate 41. This arrangement facilitates the layout of the gas pipeline.

[0105] In some embodiments, such as Figure 13 As shown, Figure 13This is a structural diagram of a fully top-intake gas stove provided in some embodiments of this application. The fully top-intake gas stove 100 also includes a housing 9; see below for details. Figure 14 , Figure 14 This is a cross-sectional view of a fully top-intake gas stove provided in some embodiments of this application. The housing 9 has a receiving space 91, and a portion of the base 4 is disposed in the receiving space 91 of the housing 9 and connected to the housing 9.

[0106] For example, such as Figure 12 As shown, the base 4 also includes a mounting bracket 46, which is disposed on the top plate 41 away from the first fire distributor 2 (e.g., Figure 11 The mounting bracket 46 is located on one side of the receiving space 91 (as shown), and is connected to the top plate 41. The end of the mounting bracket 46 away from the top plate 41 is located in the receiving space 91 (as shown). Figure 14 As shown, the base 4 is located within the housing 9 and connected to it. It is understood that the base 4 may also include a support column, which is disposed on the side of the top plate 41 near the first fire distributor 2 and connected to the top plate 41. The support column is connected to the first fire distributor 2 and the first ejector tube 3, and is used to support the first fire distributor 2 and the first ejector tube 3. A limiting groove may be provided at the position corresponding to the first fire distributor 2 and the first ejector tube 3 and the first support column, and the first support column is located within the limiting groove.

[0107] Based on this, such as Figure 13 As shown, the fully top-intake gas stove 100 may also include a liquid collection tray 10, which is disposed on the top plate 41 (e.g., Figure 11 (as shown) and gas collection hood 5 (as shown) Figure 11 The liquid tray 10 and the gas collecting hood 5 are connected to the housing 9. In this case, there is a gap between the liquid tray 10 and the gas collecting hood 5 for air circulation. In this way, air can enter the air intake channel 52 through the gap and enter the ejector chamber 51 through the air intake channel 52 to achieve primary air replenishment.

[0108] At this time, as Figure 13 As shown, the fully top-intake gas stove 100 may also include an energy-concentrating ring 20, which is positioned on the liquid collection tray 10 near the gas collection hood 5 (e.g. Figure 11 (as shown) on one side, and surrounding the first flame cap 1 (as shown) Figure 1 The energy-concentrating ring 20 is arranged around its periphery (as shown). Multiple support legs 201 are provided on the energy-concentrating ring 20 (such as...). Figure 14 As shown, the liquid collection tray 10 has multiple grooves on the side near the energy-concentrating ring 20, with each support leg 201 corresponding to one groove and located within the corresponding groove. This helps improve the stability of the energy-concentrating ring 20 during installation. It is understood that there is a gap between the energy-concentrating ring 20 and the liquid collection tray 10 to allow air to pass through.

[0109] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0110] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of protection described in the claims.
