Those holes are vulnerable to 2 break up during the bending process of the tube; and in worse case, those o holes on the outer wall of the tube are deformed when pulled laterally and others on the inner wall are also deformed when laterally compressed resulting in inconsistent burning capacity. To correct this problem, another process is required after the bending of the tube. The space for the process however is limited to the tube spacing on the inner side making the process of the tube burner of the prior art minute and complicated, thus higher production cost to fail fast production. Furthermore, the thickness of the tube naturally determines the service life of the tube wall housing the flame hole. Usually, the thicker tube gives longer service life forthe tube wall. However, the thickness of the tube is limited to a certain range to permit punch process.
Thicker tube means heavier tube burner to fruistrate the idea of having the punched instead of cast production with thin metal tube for easier handling of the tube burner. The thin tube burner has its flame holes preset ex-factory to a limited length of flame for longer service life of the burner at the expense of shortened heatng efficiency. As a result the fire is weak and not consistent for being subject to the air currents nearby, and that burner certainly is not meeting the fast cooking as demanded in a restaurant.
z 3 SUMMVARY OF THE INVENTION 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 o 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 formn 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.
Mnother purpose of the present invention is to provide an improved construction of a thiin 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 torn Z 4 up by the punching force or the fuiel ejection pressure. It is also free of folding marks to prevent from being subject to sheath damage. Accordingly, 0 given with the same weight of the tube bumner, the present invention provides o 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.
The foregoing object and summary provide only a brief introduction to the present invention. To frilly appreciate these and other objects of the present invention as well as the invention itselt, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.

Z 6 DETAiLED DESCRIPTON OF THE PREFERRED EMBODIENTS The following descriptions are 'of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention.
Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
Refenring to Figs. 3 through 8, a first preferred embodiment of the present invention is related to a U shaped thin tube burner provided with multiple flame holes 11, 12, 13, 21, 22, 23 in rows respectively disposed on both sides of the tube. Both sides of the tube are punched into multiple walls 20 in a shape of a lip slightly protruding from the sides of the tube.
Those flame holes 11, 12, 13, 21,P22, 23 are punched at an angle practically vertical to the tip of the lip through the wall at the tip of the lip recessed between two abutted walls 10, 20 in one punch process. As illustrated in Fig.
7, the thickness of the walls 10, 20 extending horizontally from both sides is increased. In the punch process, the side wall at higher position is first punched to form the walls 10, 20 before subsequently punching out those flame holes 11, 12, 13, 21, 22, 23 at the same time to eliminate the possible Z 7 breakage of those flarneholes 11, 12, 13, 21, 22, 23 due to the initial momentum created by punching the wballs 10, 20. The imnproved structure of 0 the walls 10, 20 and those multiple flame holes 11, 12, 13, 21, 22, 23 ensures o of the consistent production quality of the thin tube burner. The construction of those flame holes 11, 12, 13, 21, 22, 23 in rows respectively provided on both sides of the tube permit easy process to reduce manufacturing procedure and save production cost without being subject to the limited tube range for flrther process on the inner side of the tube bent into a U shape as found with the prior art. The walls 10, 20 in lip shape give solid and sturdy flame hole walls I A, Ii1B, 12A, 12B, 13A, 13B, 2 1A, 21IB, 22A, 22B, 23A, 23B surrounding respective flame holes 11, 12, 13, 21, 22, 23 for the tube burner of the present invention to provide longer service life and more consistent burning efficiency thani the prior art does.
Now referring to Fig. 9 for a second preferred embodiment of the present invention, the improved structure of the walls 10, 20 and those flame holes 11, 12, 13, 21, 22,23 maybe applied to a straight tube burner. As illustrated in Fig. 10, with the special construction of the walls 10, 20 and those flame holes 11, 12, 13, 2 1,22, 23 reserved, the cross section of the tube may be punched into a covering shape different from that of the U-shape tube burner.
08 It will be understood that each of the elements described above, or two or 0 0 0 It will be understood that each of the elements described above, or two or A more together may also find a useful application in other types of methods 0 0differing from the type described above.
0While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
