Description

Technical Field

[0001] This utility model relates to the technical field of gas oven equipment, and in particular to a dual-inlet gas burner. Background Technology

[0002] As is well known, a gas oven is an appliance used to bake food, such as a barbecue oven or a pizza oven. It has a specific baking chamber and a burner installed inside the baking chamber. The burner is connected to a gas source and sends gas out from the combustion hole for combustion. A pizza oven is an oven specifically designed for baking pizza.

[0003] Currently, most pizza ovens use single-sided air intake pipes with several individual round holes for the flame. During use, this can easily lead to flame explosions, flame lift-off, or excessive smoke emissions. This is primarily due to insufficient mixing of internal air (oxygen) and fuel gas, resulting in energy waste and low flame temperatures. Furthermore, limited fuel pressure and injection distance limit the length of the single-sided combustion zone, preventing the design of longer combustion areas. This necessitates the use of multiple burners in wider gas ovens to meet design requirements. The design and installation of these multiple burners restrict internal space, resulting in larger components and a larger overall size, which is inconvenient for daily use.

[0004] Therefore, it is necessary to improve existing gas burners. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a gas burner with dual air intake.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dual-intake gas burner includes a combustion tube and two intake pipes. The two intake pipes are fixedly installed at both ends of the combustion tube and are interconnected. One end of the intake pipe connected to the combustion tube has a funnel-shaped mixing chamber. The inlet of the intake pipe is provided with a matching head for receiving a gas nozzle, so that the gas nozzle is located at the center of the inner tube of the intake pipe. The end of the intake pipe near the inlet has a mesh opening for air entry. The combustion tube has a flame nozzle. The center of the inner tube of the combustion tube has a baffle for isolating the gas from both ends.

[0008] Preferably, the combustion tube or intake tube is provided with a mounting bracket for mounting the ignition needle.

[0009] Preferably, the lower ends of both ends of the combustion tube are provided with support frames.

[0010] Preferably, the intake pipe and the combustion pipe are at a 90° angle.

[0011] Preferably, the flame nozzles are semi-circular and arranged side by side on the combustion tube, with the same spacing between them.

[0012] By adopting the above-mentioned solution, the dual-intake combustion tube of this invention can be made longer. Combined with a baffle in the middle, the air from both ends meets at the center of the combustion tube, generating resistance and spraying a more intense flame. This allows the center of the food to reach the cooking effect more quickly. The low-pressure zones on both sides and the high-pressure zone in the middle work together to prevent the food from burning, thus achieving a fast cooking effect. At the same time, the funnel-shaped mixing chamber serves as the mixing area for gas and air. When high-pressure gas is injected into the center of the pipe from the outside, the air is driven by the pressure difference and high-speed airflow to generate a vortex effect in the mixing chamber, allowing the gas and air to mix fully. This prevents incomplete combustion due to insufficient gas mixing, effectively avoiding flame explosion, flame lift-off, and excessive smoke, thus improving the safety of gas combustion.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They 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, and therefore should not be construed as a limitation of this utility model. Furthermore, 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 indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly 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 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 communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0019] like Figures 1 to 3 As shown in the figure, this embodiment provides a dual-intake gas burner, including a combustion tube 1 and two intake pipes 2. The two intake pipes 2 are respectively fixedly installed at both ends of the combustion tube 1. The intake pipes 2 and the combustion tube 1 are interconnected. The end of the intake pipe 2 connected to the combustion tube 1 is provided with a funnel-shaped mixing cavity 3. The inlet of the intake pipe 2 is provided with a matching head 4 for receiving the gas nozzle, so that the gas nozzle is located at the center of the inner tube of the intake pipe 2. The end of the intake pipe 2 near the inlet is provided with a mesh opening 5 for air to enter. The combustion tube 1 is provided with a flame nozzle 6. The center of the inner tube of the combustion tube 1 is provided with a baffle 7 for isolating the gas from both ends. The combustion tube 1 or the intake pipe 2 is provided with a mounting bracket 8 for installing an ignition needle.

[0020] It should be noted that the gas nozzles mounted on the fitting head 4 are pressurized gas nozzles from gas cylinders. When the gas is opened by the gas regulating valve (external equipment, not shown in the figure), the gas is injected directly from the center of the intake pipe 2. The air in the mesh opening 5 then enters the funnel-shaped mixing cavity 3 under the influence of pressure difference and high-speed airflow. The pipe narrows, and a vortex effect is generated during the flow. The gas and air are injected into the cavity of the combustion pipe 1 at high pressure and high speed. Since the intake pipe 2 and the combustion pipe 1 are at a 90° angle, the gas passes through a right angle... The connection design reduces airflow and speed, creating a low-pressure zone between the two right-angle connectors and the first flame nozzle 6 closest to the connector, ensuring thorough mixing of gas and air. The mixed gas is ignited through the ignition valve. The semi-circular flame nozzles 6, arranged side-by-side on the combustion tube 1 with equal spacing, emit a uniform, regular, rolling, and swaying flame, resembling waves. Compared to the straight flame from traditional round holes, this rolling and swaying flame not only meets the requirements for efficient and uniform cooking but also offers a more visually appealing rolling flame effect. Furthermore, the dual air intakes allow for a longer combustion tube 1, spanning a wider cooking area without requiring multiple combustion tubes. A baffle 7 in the middle ensures that the air from both intakes meets at the center of the combustion tube, generating resistance and resulting in a more intense flame. This allows the center of the food to cook more quickly. The combined effect of the low-pressure zones on both sides and the high-pressure zone in the middle prevents food from burning, resulting in rapid cooking.

[0021] Meanwhile, support frames 9 are provided at the lower ends of both ends of the combustion tube 1, so that the combustion tube 1 is suspended, which serves as heat insulation and protection on the one hand, and raises the flame on the other hand, making it easier to transfer the flame temperature to the cooking area.

[0022] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
