Description

Technical Field

[0001] This utility model relates to the field of commercial gas cooking appliances, and in particular to a U-shaped burner for a pizza oven. Background Technology

[0002] In order to achieve stable combustion, traditional U-shaped burners typically have their gas inlet pipe centrally located, with equal path lengths on both sides of the U-shaped pipe, resulting in equal gas inlet and distribution pressures.

[0003] When traditional U-shaped burners are used in pizza ovens, pizza chefs need to avoid the gas inlet pipe in the middle of the oven when feeding, taking out, or rotating pizzas. This obstructs the operating space and increases the difficulty of operation. Utility Model Content

[0004] The purpose of this invention is to provide a U-shaped burner for pizza ovens to solve the above-mentioned problems.

[0005] According to one aspect of the present invention, a U-shaped burner for a pizza oven is provided, comprising: a gas inlet pipe and a U-shaped ejector tube, wherein a plurality of first flame injection holes are arranged on the inner arc sidewall of the U-shaped ejector tube, and the gas inlet pipe is offset to one side of the middle region of the U-shaped ejector tube, such that the U-shaped ejector tube forms a long side arm and a short side arm of unequal length; an axially adjustable baffle rod is provided on the side of the short side arm near the gas inlet pipe, and the baffle rod partially blocks the airflow channel of the short side arm to balance the gas distribution pressure of the long side arm and the short side arm.

[0006] In some embodiments, a threaded hole is provided on the side of the short side arm near the gas intake pipe, and the baffle rod is a threaded rod that is screwed into the threaded hole; rotating the baffle rod can continuously adjust its depth into the short side arm to change the blockage area of ​​the airflow channel.

[0007] In some embodiments, a baffle is provided outside the junction of the long side arm and the short side arm, and a second flame jet hole is provided on the baffle.

[0008] In some embodiments, the outer ends of the long side arm and the short side arm are both closed-end structures, and the distance between the closed end and the nearest first flame jet hole is ≥10mm.

[0009] In some embodiments, the length ratio of the long side arm to the short side arm is 1.2:1 to 1.5:1.

[0010] Compared with the prior art, the beneficial effects of this application are as follows:

[0011] This application forms a U-shaped tube with long and short arms by offsetting the gas inlet pipes and setting an adjustable-depth baffle bar on the short arm. The baffle bar blocks part of the airflow channel, dynamically compensating for the gas pressure imbalance caused by the path difference, so that the flame injection pressure on the long and short sides is closer to the same. The offset gas inlet pipe can give pizza chefs more operating space, ensuring operational safety while improving oven temperature uniformity. It has the advantages of simple structure, low cost and convenient control. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] refer to Figures 1 to 3 This application provides a U-shaped burner for a pizza oven, including: a gas inlet pipe 1 and a U-shaped ejector tube. The inner arc sidewall of the U-shaped ejector tube is provided with a plurality of first flame injection holes 2. The gas inlet pipe 1 is biased and connected to one side of the middle region of the U-shaped ejector tube, so that the U-shaped ejector tube forms a long side arm 3 and a short side arm 4 of unequal length. An axially adjustable baffle bar is provided on the side of the short side arm 4 near the gas inlet pipe 1. The baffle bar partially blocks the airflow channel of the short side arm 4 to balance the gas distribution pressure of the long side arm 3 and the short side arm 4.

[0017] In some embodiments, a screw hole 5 is provided on the side of the short side arm 4 near the gas intake pipe 1, and the baffle rod is a threaded rod that is screwed into the screw hole 5; rotating the baffle rod can continuously adjust its depth into the short side arm 4 to change the blockage area of ​​the airflow channel.

[0018] In some embodiments, a baffle 6 is provided at the junction of the long side arm 3 and the short side arm 4. A second flame jet hole 7 is provided on the baffle 6. The flame of the first flame jet hole 2 corresponding to the gas inlet pipe 1 is stronger than that of the first flame jet hole 2 at other positions under the action of gas pressure. The baffle 6 can reduce the fire intensity at this position.

[0019] In some embodiments, the outer ends of the long side arm 3 and the short side arm 4 are both closed-end structures, and the distance between the closed end and the nearest first flame jet hole 2 is ≥10mm.

[0020] In some embodiments, the length ratio of the long side arm 3 to the short side arm 4 is 1.2:1 to 1.5:1.

[0021] When using this application, observe the flames of the long side arm 3 and the short side arm 4, and adjust the spoiler rod to make the flames on both sides appear at the same height and in a blue state.

[0022] This application forms a U-shaped tube with long and short arms by offsetting the gas inlet pipe 1, and sets an adjustable-depth baffle bar on the short side arm 4. The baffle bar blocks part of the airflow channel, dynamically compensates for the gas pressure imbalance caused by the path difference, and makes the flame injection pressure on the long and short sides more consistent. The offset of the gas inlet pipe 1 can give pizza chefs more operating space, and improve oven temperature uniformity while ensuring operating safety. It has the advantages of simple structure, low cost and convenient control.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
