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] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" 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 mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0039] like Figure 1 and Figure 2 As shown, the upper end of the existing fire duct shell 2 is provided with a groove for fixing the fire hole plate 3. The fire hole plate 3 is embedded in the groove, thus creating gaps 4 between the fire hole plate 3 and the fire duct shell 2 at both ends along its length during the production process; for example... Figures 1 to 5 As shown, this application provides a burner, which includes a housing 1, a burner shell 2 and a burner perforation plate 3 disposed inside the housing 1, the burner perforation plate 3 being installed on the upper end of the burner shell 2, the burner also includes a first baffle 5, two first baffles 5 are provided, both of the first baffles 5 are located inside the housing 1, and the two first baffles 5 are respectively located at both ends of the burner perforation plate 3 along the length direction, the first baffle 5 includes a first plate 51, the first plates 51 are spaced apart above the burner perforation plate 3, the orthogonal projection of the first plate 51 onto the burner perforation plate 3 covers the gap 4 formed between the end of the burner perforation plate 3 along the length direction and the burner shell 2.
[0040] The projection of the first plate 51 onto the fire hole plate 3 covers the gap 4 formed between the end of the fire hole plate 3 along its length and the fire exhaust shell 2. When the gas leaks from the gap 4, it will be blocked by the first plate 51, causing the gas to flow towards the center of the fire hole plate 3. This allows the gas leaking from the gap 4 to participate in combustion, making the combustion more complete, improving combustion efficiency, and reducing flue gas emissions.
[0041] In some embodiments, the distance between the first plate 51 and the fire hole plate 3 is 0.5mm-2mm to avoid the distance being too small and obstructing the passage of leaked gas, while also avoiding the distance being too large, which would prevent the leakage of gas from being guided.
[0042] like Figure 1 , Figure 4 and Figure 5As shown, in some embodiments, multiple burner housings 2 are provided, arranged side-by-side with intervals, thereby forming a gas supply channel between adjacent burner housings 2. The first plate 51 extends along the direction of the side-by-side intervals of the burner housings 2 to cover the multiple gaps 4 formed. In addition, the outer shell 1 is surrounded by surrounding plates 11 and a lower bottom plate 12. The lower bottom plate 12 is provided with an air inlet 13, which connects to the gas supply channel. Air flows into the outer shell 1 through the air inlet 13, and then flows towards the flame holes of the flame hole plate 3 through the first plate 51, thereby guiding the supplied air and allowing the supplied air to participate in complete combustion, further improving combustion efficiency.
[0043] like Figure 1 and Figure 3 As shown, in some embodiments, the first baffle 5 is detachably connected to the outer casing 1, facilitating disassembly and assembly, and simplifying production and maintenance. Specifically, the first baffle 5 also includes a second plate 52, which is also positioned above the fire hole plate 3. The second plate 52 is connected to the first plate 51 and forms a non-flat angle with the first plate 51; exemplarily, the angle is less than or equal to 90° and greater than 0°. A fixing structure is provided at the connection between the second plate 52 and the first plate 51, allowing for detachable installation onto the outer casing 1 via this fixing structure. In some alternative embodiments, the fixing structure may also be provided on the second plate 52, or fixing structures may be provided at both the connection between the second plate 52 and the first plate 51 and on the second plate 52 itself. Exemplarily, the fixing structure is a mounting hole 54, and the outer casing 1 is provided with a hook that mates with the mounting hole 54, thereby stabilizing the first baffle 5 by hanging it on the hook through the mounting hole 54. In some other embodiments, a screw hole may be provided on the outer casing 1, allowing for screw fixing through the mounting hole 54. It is understandable that the fixing structure could also be a hook set on the second plate 52.
[0044] In some embodiments, a through hole 55 is provided at the connection between the first plate 51 and the second plate 52. This through hole 55 allows flames below the first plate 51 to pass through, guiding and correcting the flames, while also reducing direct combustion of the outer casing 1 by the flames, potentially lowering the temperature of the outer casing 1. Furthermore, the through hole 55 corresponds to the flame perforation plate 3. In the current embodiment, since multiple flame exhaust shells 2 are arranged side-by-side, multiple through holes 55 are also correspondingly provided. It should be noted that the aforementioned distance between the first plate 51 and the flame perforation plate 3 ensures that the gas leaking from the gap 4 is preferentially guided to the center of the flame perforation plate 3 and does not directly pass through the through hole 55. Additionally, when the fixing structure is the mounting hole 54 at the connection between the first plate 51 and the second plate 52, some of the mounting holes 54 can be used as through holes 55. Providing mounting holes 54 and through holes 55 at the connection between the first plate 51 and the second plate 52 can also reduce heat conduction from the first plate 51 to the second plate 52, minimizing the temperature of the second plate 52.
[0045] like Figure 1 and Figure 3 As shown, in some embodiments, the first baffle 5 further includes a third plate 53, which is connected to the end of the second plate 52 away from the first plate 51. The third plate 53 is offset relative to the second plate 52 towards the center of the burner, that is, the third plate 53 is spaced apart from the outer casing 1, thereby forming a gap between the third plate 53 and the outer casing 1. This can both concentrate the flame and provide heat insulation. Furthermore, a protrusion 56 is provided on the side of the third plate 53 away from the center of the burner, and the protrusion 56 abuts against the outer casing 1 to ensure the stability of the third plate 53. Exemplarily, the protrusion 56 is formed by a recess in the third plate 53.
[0046] Understandably, the burner also has an ignition assembly, which includes an ignition needle 6; of course, the ignition assembly also includes other control components besides the ignition needle 6, which will not be described in detail here; such as Figure 1 As shown, in some embodiments, both the second plate 52 and the outer casing 1 are provided with through holes 57. The ignition needle 6 passes through the through holes 57 into the outer casing 1. The ignition needle 6 and the ignition plate 3 are located on opposite sides of the first plate 51. On the horizontal projection plane, the orthographic projection of the ignition end of the ignition needle 6 is located within the orthographic projection range of the first plate 51, thereby avoiding the possibility of the flame directly burning the ignition end. At the same time, the through holes 57 can also reduce the heat conduction from the second plate 52 to the third plate 53, lowering the temperature of the third plate 53.
[0047] In some embodiments, a second baffle 7 is further provided inside the outer casing 1. The two second baffles 7 are disposed on opposite sides of the fire vent casing 2, and the second baffles 7 are located between two opposite first baffles 5. By providing the second baffles 7, the direct radiation of the flame to the outer casing 1 is reduced, thereby minimizing the temperature of the outer casing 1. It should be noted that the form of the second baffle 7 is not specifically limited.
[0048] This application also provides a gas water heater, which includes a housing and the aforementioned burner, with the burner disposed inside the housing. By providing a first plate 51 in the burner, the emission of flue gas is reduced and the product quality is improved.
[0049] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.
[0050] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
