Description

Technical Field

[0001] This utility model relates to the technical field of gas-fired oven equipment, and in particular to a single-sided 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 straight-through round tubes as burners, with several individual round holes for the flame nozzles. During use, it is found that this can easily lead to flame explosions, flame lift-off, or excessive smoke. The main reason for this is that the internal air (oxygen) and fuel gas do not mix sufficiently. This also results in energy waste and low flame temperature.

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

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a single-sided gas burner that can fully mix gas and air.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A single-sided gas burner includes an intake pipe, a combustion pipe, and an ignition needle fixedly mounted on the combustion pipe. The intake pipe is connected to the gas pipe, and the junction of the intake pipe and the gas pipe is an arc-shaped bend. The intake pipe has a flared opening at its inlet, causing the diameter of the intake pipe to gradually decrease. A mounting bracket is provided at the inlet of the intake pipe, and the mounting bracket has mounting holes for mounting gas nozzles. When the gas nozzle is mounted in the mounting holes, the gas nozzle is directly opposite the center of the flared opening, and a gap is reserved around the gas nozzle and the flared opening to allow air to enter. The combustion pipe has a flame nozzle, and the tip of the ignition needle is placed at the flame nozzle.

[0008] Preferably, the combustion tube is provided with a fixing seat, the fixing seat is fixedly connected to the combustion tube, the bottom of the fixing seat is fixedly installed on the oven, and the insulating part of the ignition needle is fixedly installed on the fixing seat.

[0009] Preferably, the degree of the arc-shaped corner is 90°.

[0010] Preferably, the flame nozzles are semi-circular and arranged side by side on the combustion tube, with the same spacing between them.

[0011] By adopting the above-mentioned solution, this utility model designs the intake pipe opening with a flared mouth, making the intake pipe opening narrower. This allows high-pressure gas to be injected from outside the pipe opening into the center, and the air is then driven by the pressure difference and high-speed airflow to generate a vortex effect inside the intake pipe. Combined with the arc-shaped corner design, the gas and air can be fully mixed, making the mixing smoother and more uniform. Incomplete combustion due to insufficient gas mixing is prevented, effectively avoiding flame detonation, flame lift-off, and excessive flue gas, 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.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0016] 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.

[0017] like Figure 1 and Figure 2 As shown, this embodiment provides a single-sided gas burner, including an intake pipe 1, a combustion pipe 2, and an ignition needle 3 fixedly installed on the combustion pipe 2. The intake pipe 1 is connected to the gas pipe 2, and the junction of the intake pipe 1 and the gas pipe 2 is an arc-shaped bend 4. A flared mouth 5 is provided at the opening of the intake pipe 1, so that the diameter of the intake pipe 1 gradually decreases. A mounting bracket 6 is provided at the opening of the intake pipe 1. The mounting bracket 6 is provided with a mounting hole 7 for mounting a gas nozzle. When the gas nozzle is mounted in the mounting hole 7, the gas nozzle is directly opposite the center of the flared mouth 5, and a gap is reserved around the gas nozzle and the flared mouth 5 to allow air to enter. The combustion pipe 2 is provided with a flame nozzle 8, and the tip of the ignition needle 3 is placed at the flame nozzle 8.

[0018] It should be noted that the gas nozzle mounted on the mounting bracket 6 is a gas nozzle from a pressurized gas canister, while the other end of the ignition needle 3 is connected to the ignition valve. When the gas is opened by the gas regulating valve (external device, not shown in the figure), the gas is injected at high speed into the center of the narrow bell mouth 5 under high pressure. Air is also brought in, and the air then generates a vortex effect under the drive of the pressure difference and high-speed airflow. The gas and air are injected into the cavity of the combustion pipe 2 at high pressure and high speed. The degree of the arc corner 4 is a 90° bend (the arc corner 4 has less resistance than a right angle, and the arc corner combined with the vortex effect makes the gas flow and mixing smoother and more efficient). The gas mixture is uniform, preventing incomplete combustion due to insufficient gas mixing, which could lead to flame explosions, flame lift-off, or excessive smoke. The area between the first flame nozzle 8 closest to the curved corner 4 is a fully mixed zone 101 for gas and air. The mixed gas is ignited by the ignition needle 3. The semi-circular flame nozzles 8, arranged side-by-side on the combustion tube 2 with equal spacing, produce a uniform, regular flame that rolls and sways like waves. Compared to the straight flame from traditional round nozzles, 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.

[0019] Furthermore, regarding the installation of the ignition needle 3, a fixing seat 9 is provided on the combustion tube 2 in this embodiment. The fixing seat 9 is fixedly connected to the combustion tube 2. The bottom of the fixing seat 9 is fixedly installed on the oven, and the insulating part 102 of the ignition needle 3 is fixedly installed on the fixing seat 9.

[0020] 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.
