Problems solved by technology

If this is done, the distance between the fire transmission hole and the main burner fire hole will be increased, resulting in the undesirable problem of reduced fire transmission.
[0007] In addition, when the above-mentioned convex portion is provided on the upper wall of the main burner cover and a fire transmission hole is formed on the convex portion, especially when a plurality of convex portions are to be provided, the fire transmission must be carried out for each convex portion one by one. Hole processing operations, resulting in the problem of raising manufacturing costs due to low work efficiency

Abstract

The invention provides primary-secondary combustors and a manufacturing method thereof, and solves the problem of not only maintaining good flame transfer property but also manufacturing effectively with low cost. The primary-secondary combustors are provided with a secondary combustor cover and an annular main combustor cover (10) around the secondary combustor cover. The secondary combustor cover is provided with a secondary combustor fire hole, and the main combustor cover (10) is provided with a main combustor fire hole (11). A hollow convex part (14) is convexly arranged on an upper wallpart (13) of the main combustor cover (10) between the main combustor fire hole (11) and the secondary combustor fire hole; and a pair of flame transfer holes (17, 18) is formed on the convex part (14), by using the center of the main combustor cover (10) as a cutting rotary axle center to rotate, and cutting a thick part of the convex part (14) between a longitudinal wall part (15) at the secondary combustor fire hole and a longitudinal wall part (16) at the main combustor fire hole (11) by using a lathe to process.

Description

technical field [0001] The invention mainly relates to a main and auxiliary burner for a gas stove and a manufacturing method of the main and auxiliary burner. Background technique [0002] Conventionally, as such a main and auxiliary burner for a gas stove, there is known a main and auxiliary burner for a gas stove that has an auxiliary burner cover and an annular main burner cover that surrounds the auxiliary burner cover. The peripheral wall of the auxiliary burner cover has a plurality of auxiliary burner fire holes, and the auxiliary burner fire holes are spaced in the circumferential direction; the peripheral wall of the main burner cover has a plurality of main burner fire holes. The flame holes of the main burner are spaced apart in the circumferential direction. In addition, in this kind of main and auxiliary burners, an igniter is generally used to ignite one of the fire holes of the auxiliary burner and the fire hole of the main burner, so that the other fire hol...
