Tube burner flame hole construction
A tube burner flame hole construction with both sides of the tube provided with a row of multiple flame hole walls; each wall being compressed in a shape of a lip with both sides slightly protruding outwardly from the tube; a hole being provided in the center of the recessed lip to facilitate the punching process and improve structural strength of the of the entire tube burner, flame hole being more sturdy and thicker for consistent burning effects and longer service life of the tube burner.
(a) Technical Field of the Invention
The present invention is related to an improved construction of flame holes on a tube burner, and more particularly to one that provides walls housing those flame holes improved structural strength, consistent burning effects and longer service life of a burner generally used for a mantelshelf in a restaurant.
(b) Description of the Prior Art
The oven used in a mantelshelf in a restaurant is usually different from that of a domestic one, and the structure of the burner in the mantelshelf is also drastically different from a domestic burner. So far, the commercial burner is usually made in an “T” or a “U” shape. The tube burner is adapted with an inlet of fuel gas connected to a source such as a gas cylinder. All other openings are sealed either by press or welding. Both sides of the tube are disposed with multiple minute flame holes in a row so that when the fuel gas is admitted, the fuel gas ejected out of those holes is immediately ignited to heat the oven or to directly heat a cooking utensil as desired.
However, the opening of those holes on the wall of the tube one by one either with a drill or a chisel involves numerous processes, particularly with a U shape tube burner. As illustrated in
The primary purpose of the present invention is to provide an improved construction of a thin burner wall that houses the flame hole to simplify the process of the thin tube burner. To achieve the purpose, at where the flame holes to be provided on both sides of the tube are compressed to form multiple walls each in the form of a thick lip and a flame hole punched at the same time through the wall at the recessed lip tip at an angle practically vertical to the tip of the lip.
Another purpose of the present invention is to provide an improved construction of a thin burner wall that allows one punching process to come up with all flame holes even the tube is bent into a U shape while maintaining the tube in an integral part.
Yet another purpose of the present invention is to provide an improved construction of a thin burner wall. The mass density of the wall punched in a lip shape is increased with the thick wall lip preset at a critical arc before the punched mark is formed, thus to increase the mass density of the wall at the tip of the wall lip where the hole is punched through the tube. Given with the same thickness of the tube, the thickness of the wall of the flame hole of the present invention can be two times of that of the prior art so to provide solid and sturdy wall among those multiple flame holes to prevent from being tom up by the punching force or the fuel ejection pressure. It is also free of folding marks to prevent from being subject to sheath damage. Accordingly, given with the same weight of the tube burner, the present invention provides stronger fire and higher consistent burning efficiency than the prior art does without being interfered by air currents to meet the demands of fast cooking in a restaurant.
