Description

Technical Field

[0001] This utility model relates to the field of burner technology, specifically to a four-chamber burner with top and bottom air intake and full premixing. Background Technology

[0002] Traditional burners often use a single-cavity circular opening structure to mix gas and air, which results in insufficient mixing and insufficient gas supply, leading to low combustion efficiency and high emissions. At the same time, the air supply channel of some burners is limited by the internal space of the bottom shell, resulting in insufficient air supply, which affects the combustion effect and has poor usage flexibility. Utility Model Content

[0005] Preferably, the flame cap includes an outer ring flame cap, a central flame cap, and a middle ring flame cap. The outer ring independent cavity is connected to the outer ring flame cap, and the outer ring flame cap has multiple combustion holes arranged circumferentially upward.

[0006] Preferably, the central independent cavity is connected to the central flame cap, and the central flame cap has multiple combustion holes on its circumferential side.

[0007] Preferably, the independent cavity of the middle ring is connected to the middle ring burner cap, and the middle ring burner cap is provided with multiple combustion holes in the circumferential direction.

[0008] Preferably, the burner head is provided with a gas / air mixing and conveying channel, and the burner head is fixedly connected to the cooktop panel.

[0009] Compared with the prior art, the beneficial effects of this utility model are: The outer ring independent cavity adopts an elliptical structure with an arc, which improves the mixing degree and gas supply of gas and air, making the combustion more complete; the direct injection channel of the central independent cavity can supplement air when the direct injection function is not used, promote the combustion of the central flame, reduce emissions, and improve thermal efficiency; the central ring independent cavity is located above the cooktop panel, not restricted by the bottom shell, ensuring sufficient air supply and convenient use.

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0013] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0014] See Figures 1-4As shown, this specific embodiment adopts the following technical solution: including: a burner head, the burner head is provided with a cooktop panel, the cooktop panel is provided with a flame distributor, the flame distributor is provided with a flame cap, the outermost layer of the burner head is provided with an outer ring independent cavity, the outer ring independent cavity is an arc-shaped elliptical structure, the arc-shaped elliptical structure achieves a more complete gas mixing effect and a more sufficient gas supply compared with the traditional circular structure, the innermost layer of the burner head is provided with a central independent cavity, the center of the central independent cavity is provided with a direct injection channel, the direct injection channel provides additional air supplement to the central flame when the direct injection auxiliary function is not used, so that the central flame burns more completely, the outer ring independent cavity and the central independent cavity are lower air intake channels, the upper part of the cooktop panel is provided with a middle ring independent cavity, the middle ring independent cavity is independently set with respect to the outer ring independent cavity and the central independent cavity, the independent cavity is located above the cooktop panel and is not limited by the internal space of the bottom shell, and can provide sufficient air supplement, the middle ring independent cavity is an upper air intake channel.

[0015] The burner includes an outer ring burner, a central burner, and a middle ring burner. The outer ring independent cavity is connected to the outer ring burner. The outer ring burner has multiple combustion holes circumferentially upward, and these combustion holes are evenly distributed along an arc-shaped elliptical contour to form a stable outer ring flame. The central independent cavity is connected to the central burner. The central burner has multiple combustion holes circumferentially on its side. The central combustion hole of the central burner surrounds the direct injection channel to form a ring-shaped central flame. The middle ring independent cavity is connected to the middle ring burner. The middle ring burner has multiple combustion holes circumferentially upward. The burner head is equipped with a gas / air mixing and delivery channel. The gas / air mixing and delivery channel fully mixes the gas and air through a premixing device and then delivers them to the outer ring independent cavity, the central independent cavity, the middle ring independent cavity, and the direct injection channel, forming four independent cavities. The burner head is fixedly connected to the cooktop panel.

[0016] The working principle of this specific implementation method is as follows: four independent cavities (outer ring independent cavity, central independent cavity, middle ring independent cavity, and direct injection channel) are arranged in concentric circles, each with its own independent gas supply and air mixing system. The outer ring independent cavity adopts an innovative arc-shaped elliptical structure, which significantly improves the mixing effect; the middle ring independent cavity adopts a full top air intake and horizontal injection design, so that air is directly drawn in from above the cooktop panel, without being restricted by the bottom space; the central independent cavity has a reserved direct injection channel, which can provide auxiliary firepower as needed.

[0017] This specific implementation uses an arc-shaped elliptical structure in the outer ring independent cavity to improve the mixing degree and gas supply of gas and air, resulting in more complete combustion; the direct injection channel of the central independent cavity can supplement air when the direct injection function is not used, promoting central flame combustion, reducing emissions, and improving thermal efficiency; the central independent cavity is located above the cooktop panel, not restricted by the bottom shell, ensuring sufficient air supply and convenient use.

[0018] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and not restrictive in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description; thus, all variations falling within the meaning and scope of equivalents of the claims are included within this invention.

[0019] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
