Description

Technical Field

[0001] This utility model relates to the field of stove head technology, and in particular to a stove head specifically designed for commercial fuel-fired wok stoves. Background Technology

[0002] The burner head is the core component in various combustion equipment (such as stoves, boilers, industrial burners, etc.) used to control the mixing of fuel and air and ignite combustion. Its design directly affects combustion efficiency, flame stability, energy consumption and pollutant emissions.

[0003] In commercial kitchens, oil-fired woks are commonly used cooking equipment. However, existing commercial oil-fired wok burners often suffer from incomplete combustion and splattering due to the use of liquid fuel oil. Furthermore, the flames are unevenly distributed, resulting in heat not being effectively concentrated on the bottom of the pan, leading to low thermal efficiency, significant fuel waste, and insufficient practicality. Therefore, it is necessary to redesign a burner specifically for commercial oil-fired woks to address these issues. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a special burner head for commercial fuel-fired wok stoves.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A commercial fuel-fired wok burner includes a burner base. An air inlet pipe is fixedly installed on the outer wall of the burner base, extending into the interior of the burner base. An installation groove is formed on the upper surface of the burner base, and a flame distributor is fixedly installed inside the installation groove. A flame retarder is slidably installed inside the installation groove of the burner base. Multiple first flame inlets are formed at the bottom of the flame retarder, and the first flame inlets are staggered at the bottom of the flame retarder. Multiple second flame inlets are formed on the outer wall of the flame retarder, and the second flame inlets are evenly distributed around the circumference of the outer wall of the flame retarder. A flame-dividing fin is slidably installed on the upper surface of the flame retarder. An ignition cover is fixedly installed on the upper surface of the burner base, and a limiting groove is formed on the upper surface of the ignition cover. A flame-gathering ring is slidably installed inside the limiting groove.

[0007] Preferably, the fire distributor includes an annular base and spiral guide vanes disposed on the annular base, with a guide channel of 2-3 mm in width formed between adjacent spiral guide vanes.

[0008] Preferably, the flame spreader includes a central connecting post and a plurality of flame spreader blades distributed around the central connecting post. The flame spreader blades have an arc-shaped structure, and the width of the flame spreader blades gradually decreases from the center to the edge.

[0009] Preferably, the bottom of the limiting groove of the ignition cover is provided with an elastic sealing ring, which is made of high-temperature resistant silicone rubber.

[0010] Preferably, the flame-gathering ring is cylindrical, and the inner wall of the flame-gathering ring is provided with a high-temperature resistant ceramic coating.

[0011] The beneficial effects of this utility model are:

[0012] 1. By setting up components such as flame delayers, flame spreaders, and flame rings, the flame delayers will block splashed fuel and allow it to burn a second time, thus ensuring safe use of the stove, saving fuel, and reducing operating costs. At the same time, the flame spreaders and flame rings will concentrate the flame at the bottom of the pot, which will greatly improve thermal efficiency and effectively reduce fuel consumption compared to traditional burners.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-4 A commercial fuel-fired wok burner head includes a burner base 1. An air inlet pipe 2 is fixedly installed on the outer wall of the burner base 1, extending into the interior of the burner base 1. An installation groove is provided on the upper surface of the burner base 1, and a flame distributor 3 is fixedly installed inside the installation groove. The flame distributor 3 includes an annular base and spiral guide vanes set on the annular base. A guide channel with a width of 2-3mm is formed between adjacent spiral guide vanes. The spiral guide vanes are made of high-temperature resistant stainless steel to ensure that the mixed gas forms a strong rotating vortex in the guide channel, enhancing the mixing effect of fuel and air. The 2-3mm width of the guide channel can ensure the smooth flow of the mixed gas and maintain the stability of the rotating airflow, so that the mixed gas reaches the optimal mixing state before entering the retarder 4.

[0020] A retarder 4 is slidably installed inside the mounting slot of the furnace base 1. Multiple first fire inlets 5 are provided at the bottom of the retarder 4, staggered in arrangement. Multiple second fire inlets 6 are provided on the outer wall of the retarder 4, evenly distributed around its circumference. A flame divider 7 is slidably installed on the upper surface of the retarder 4. The flame divider 7 includes a central connecting post and multiple flame divider blades distributed around the central connecting post. The flame divider blades have an arc-shaped structure, and their width gradually decreases from the center to the edge. The central connecting post is vertically fixed at the center of the upper surface of the retarder 4, made of high-strength metal, providing reliable support for the flame divider blades. The multiple flame divider blades are evenly distributed around the central connecting post. Their arc-shaped structure is designed based on flame diffusion characteristics, effectively guiding the flame to diffuse evenly in all directions. The design of the flame divider blades gradually decreasing in width from the center to the edge ensures a uniform pressure distribution during flame diffusion, preventing localized over- or under-intensity flames, thus achieving uniform fire coverage on the furnace head surface.

[0021] An ignition cover 8 is fixedly installed on the upper surface of the stove base 1. A limiting groove is opened on the upper surface of the ignition cover 8. An elastic sealing ring is set at the bottom of the limiting groove of the ignition cover 8. The elastic sealing ring is made of high-temperature resistant silicone rubber. High-temperature resistant silicone rubber has excellent elasticity and temperature resistance. It can still maintain a good sealing effect in high-temperature environments, effectively preventing the flame and high-temperature gas from leaking from the gap between the flame ring 9 and the ignition cover 8, improving the safety of the stove head, reducing heat loss, and improving thermal efficiency. The flame ring 9 is slidably installed inside the limiting groove. The flame ring 9 is cylindrical. The inner wall of the flame ring 9 is coated with a high-temperature resistant ceramic coating. The high-temperature resistant ceramic coating is evenly covered on the inner wall surface of the flame ring 9 through an advanced spraying process. This coating has extremely high high-temperature resistance and good thermal radiation characteristics. On the one hand, it can withstand the long-term burning of high-temperature flames and extend the service life of the flame ring 9. On the other hand, it can effectively reflect the heat of the flame back to the cooking area, concentrate the flame energy, enhance the heating effect of the stove head, and meet the needs of commercial wok stoves for high-temperature and high-efficiency cooking.

[0022] When this utility model is in use, the mixture of fuel and air enters the furnace base 1 through the air inlet pipe 2, and then flows into the burner 3 fixedly installed in the mounting groove. The annular base of the burner 3 is provided with spiral guide vanes, and the 2-3mm guide channel between adjacent spiral guide vanes makes the mixture form a high-speed rotating airflow. Under the action of centrifugal force, the fuel and air are fully mixed, laying the foundation for efficient combustion.

[0023] The uniformly mixed gas continues to move upward and reaches the retarder 4, which is slidably installed inside the mounting groove of the furnace base 1. The first fire inlet 5, which is staggered at the bottom of the retarder 4, allows some of the mixed gas to enter the retarder 4 in an alternating manner, slowing down the upward speed of the airflow and ensuring a complete combustion reaction. At the same time, the second fire inlet 6, which is evenly distributed around the outer circumference of the retarder 4, guides another part of the gas to the gap between the retarder 4 and the ignition hood 8, supplementing the secondary air required for combustion and maintaining flame stability.

[0024] When the ignition device is activated, the mixed gas inside and outside the retarder 4 is ignited to form a stable flame. The flame continues to rise and is then distributed a second time by the flame divider 7 that is slidably installed on the upper surface of the retarder 4. The central connecting column of the flame divider 7 stably supports multiple circumferentially distributed arc-shaped flame divider blades, and the width of the blades gradually decreases from the center to the edge. This structure can evenly spread the concentrated flame to the surrounding area, making the fire distribution on the entire burner surface more balanced and effectively avoiding local overheating.

[0025] After being dispersed by the flame spreader 7, the flame enters the flame-gathering ring 9, which is slidably installed in the limiting groove of the ignition cover 8. The high-temperature resistant silicone rubber elastic sealing ring at the bottom of the ignition cover 8 fits tightly against the flame-gathering ring 9, preventing the flame from overflowing while ensuring the sealing of the combustion area. The flame-gathering ring 9 is cylindrical, and its inner wall has a high-temperature resistant ceramic coating that can not only withstand the scorching of the high-temperature flame, but also effectively reflect heat, re-converging the dispersed flames and making the heat distribution on the entire burner surface more even. This effectively avoids local overheating, greatly improves thermal efficiency, and effectively reduces fuel consumption, making the commercial oil-fired wok stove have strong and stable firepower during cooking.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
