Description

TECHNICAL AREA The present utility model belongs to the technical field of burners and relates in particular to an oven burner tube and an oven burner. TECHNICAL BACKGROUND The burner tube is the core heating component of an oven, and its burner structure directly determines the flame distribution, heat conduction efficiency, and food baking effect. It is widely used in appliances such as built-in ovens for homes and commercial ovens. An ideal oven burner tube must achieve "comprehensive flame coverage, uniform heat distribution, and baking without dead spots" to ensure that all parts of the food are heated evenly, preventing problems such as localized burning or undercooking, while also improving the heat utilization rate to meet the baking requirements of various food shapes. Existing oven burner tubes exhibit significant deficiencies in their burnout structure design, making it difficult to meet the core requirements for even baking and highly efficient heating. The specific problems are as follows: First, existing burner tubes typically employ a linear arrangement, a disordered distribution, or a design with flame holes oriented in a single direction, without adapting the optimized layout to the circular arc contour of the tube body. The flame jet direction is either concentrated or disorderly dispersed, preventing the formation of a full-surface heating zone. Particularly on the food-baking side of the tube body, which faces the food, linear or disordered flame holes easily lead to localized heat concentration, creating pronounced temperature gradients on the food surface. This results in situations where the edges burn and the center remains undercooked, seriously compromising baking quality. Secondly, adjacent flame outlet areas of conventional burner tubes are independent of each other and lack a transition structure, which easily leads to the formation of heat gaps between the flame holes. Particularly with irregular shapes or larger foods, the areas corresponding to these heat gaps cannot be effectively covered by the flames, resulting in baking dead zones. Simultaneously, flame holes in a single direction cannot achieve multi-angled penetration by the flames, leading to insufficient three-dimensional heat penetration of the food and poor uniformity of flavor and cooking. Third, the flame holes of most burner tubes are positioned perpendicular to the tube body or horizontally, resulting in a short and scattered flame path. This allows a significant amount of heat to diffuse and be lost to the inner wall of the oven chamber instead of being directed precisely onto the food surface. Furthermore, the lack of an angled tube design leads to insufficient flame thrust and poor heat penetration. This results in low baking efficiency for thickly sliced foods, requiring longer baking times, which not only increases energy consumption but can also lead to excessive moisture loss and a poorer taste. Fourth, in some burner tubes, excessive density or an uneven arrangement of the flame holes can lead to the formation of local high-temperature zones due to flame overlap. This not only makes food prone to burning but can also accelerate the aging of the oven lining. In sparsely populated areas, the flames are weak and the heat insufficient, further exacerbating the problem of uneven heating. Simultaneously, an unbalanced flame distribution can result in incomplete combustion of the gas, producing odors or harmful gases, which poses a safety risk.
