Description

Technical Field

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

[0002] Gas-fired water heaters are equipped with burners. Existing burners have flame holes on their burner heads. When working, the fan starts, and gas enters the burner head from the injector tube for combustion. Since the burner head is a hollow cavity, the burner head is prone to airflow disturbance when the fan is drawing air, which generates a lot of noise. Utility Model Content

[0003] The purpose of this invention is to solve at least one of the technical problems existing in the prior art and to provide a low-noise burner.

[0004] The burner according to an embodiment of the present invention includes: a burner head, the burner head including at least two inner cores, each inner core having a flame hole, and a partition between two adjacent inner cores, the partition being connected to the two adjacent inner cores respectively, so as to divide the cavity below the burner head into at least two small cavities.

[0005] The burner according to the embodiment of the present utility model has at least the following beneficial effects: due to the presence of the baffle, the cavity below the burner head is divided into multiple small cavities. When the fan draws air, some of the gas below the burner head is blocked by the baffle, which plays a role in intercepting the flow, thereby effectively reducing the disturbance of the airflow in each small cavity and reducing noise.

[0006] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0012] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0013] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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 utility model.

[0014] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number.

[0015] Reference Figures 1 to 4 This utility model discloses a burner, comprising: a burner head, the burner head including at least two inner cores 10, each inner core 10 having a flame hole 11, and a partition 12 between adjacent inner cores 10, the partition 12 being connected to the adjacent two inner cores 10 respectively, to divide the cavity below the burner head into at least two small cavities 100. Due to the presence of the partition 12, the cavity below the burner head is divided into multiple small cavities 100. When the fan draws air, some of the gas below the burner head is blocked by the partition 12, which acts as a flow interceptor, thereby effectively reducing the turbulence of the airflow in each small cavity 100 and reducing noise.

[0016] Preferably, the partition 12 and the inner core 10 are an integral structure, which is convenient for processing and manufacturing. Furthermore, there is no need to weld between adjacent inner cores 10, resulting in good consistency and effectively avoiding the situation where the two inner cores 10 are not aligned or have poor consistency, which would affect combustion.

[0017] like Figure 3 As shown, the inner core 10 includes a flame hole portion 13, with flame holes 11 disposed on the surface of the flame hole portion 13. The two sides of the flame hole portion 13 are bent downward to form bending portions 14. The two adjacent bending portions 14 of two adjacent inner cores 10 are connected to form a partition 12, that is, the two adjacent inner cores 10 and the partition 12 are integrated into an M-shape, which is convenient for processing and manufacturing.

[0018] like Figure 4The front and rear ends of the burner head are respectively provided with downward baffles 15, and the baffles 15 are respectively enclosed with multiple bends 14 to form multiple small cavities 100.

[0019] like Figure 2 and Figure 3 The surface of the flame hole 13 is concave downward to form a V-shaped structure, which increases the surface area of ​​the flame hole 13 and slows down the gas flow rate at the flame hole 11, which can further reduce the noise generated by excessive flow rate.

[0020] like Figure 2 and 3 It also includes a housing with an opening at the top and an air inlet at the bottom. The burner head is positioned inside the housing through the opening. Multiple vertical ribs 23 are provided on the inner wall of the housing. The bent portions 14 on both sides of the burner head abut against the ribs 23 to form multiple pressure-stabilizing chambers 20. The upper part of each pressure-stabilizing chamber 20 communicates with the opening, and the lower part communicates with the air inlet. Part of the air-fuel mixture enters the corresponding pressure-stabilizing chamber 20, which has the function of releasing pressure at the burner head and generating a small flame to stabilize the main flame.

[0021] Furthermore, such as Figure 3 As shown, the inner wall of the pressure stabilizing chamber 20 is recessed outward to increase the volume of the pressure stabilizing chamber 20, and notches are provided on the bent portions 14 on both sides of the combustion head so that the gas can enter the pressure stabilizing chamber 20 through the notches.

[0022] like Figure 2 In some embodiments, the housing includes a detachably connected left housing 21 and a right housing 22. Multiple ribs 23 are respectively provided on the inner walls of the left housing 21 and the right housing 22. The bent portion 14 on the left side of the burner head abuts against the ribs 23 on the left housing 21 to form a pressure-stabilizing cavity 20, and the bent portion 14 on the right side of the burner head abuts against the ribs 23 on the right housing 22 to form a pressure-stabilizing cavity 20. The detachable connection of the left and right housings 22 facilitates the assembly and maintenance of the burner.

[0023] It will be readily understood by those skilled in the art that the above preferred methods can be freely combined and superimposed without conflict.

[0024] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
