Reference numeral 1 denotes a burner body, a pair of outer plates (also referred to as outer flame port forming burner bodies) 2, 2, a U-shaped inner plate (also referred to as inner flame port forming burner body) 3, and these outer plates 2 2 and the inner side plate 3 and sandwiched between the pair of flame port partition plates 4. The burner body 1 has a primary air suction section 5, a mixing tube section 6, a pressure equalizing section 7, and a number of slit-shaped flame openings 8. The flame openings 8 extend along the longitudinal direction of the burner body 1. A large number of parts are arranged side by side through alternating parts 9 to form a group,
Moreover, the groups are arranged in parallel to form a return region 10. Then, the outer plates 2 and 2 form the suction portion 5, the mixing pipe portion 6, and the pressure equalizing portion 7. Therefore, half-divided recesses are press-formed at the positions facing each other, and the flame port 8 and the flame portless portion 9 are formed. In order to form the above, the concave portion 2a and the convex portion 2b are press molded. Further, the inner plate 3 and the inner plates 2 and 2 are press-molded with the concave portions 3a and the convex portions 3b in order to form the flame port 8 on the upper surface.

The concave portion 3a and the convex portion 3b are respectively joined to 2b and joined, then the other flame port partition plate 4 and the other outer plate 2 are joined, and finally the outer and inner circumferences of the outer plates 2 and 2 are welded together. Projections 2b, 3
b, Flame openings 8 are independently formed by spot welding the flame opening partition plate 4. When the burner body 1 is assembled, the lower ends of the pair of flame port partition plates 4 and 4 are slightly bent from the center, but a gap 11 is formed in the pressure equalizing portion 7 over the entire length. 12 is a nozzle for ejecting gas.

Since the secondary air for combustion is not supplied to the portion of the inner flame port 8, the inner portion of the flame port 8 of the burner body 1 lacks the secondary air, and the length of the flame becomes longer, resulting in incomplete combustion and There was a problem that it caused the generation of harmful CO. As a means for solving this problem, there is a means for shortening the length of the flame openings 8 in the longitudinal direction and increasing the gap between the adjacent flame openings 8 to sufficiently supply the secondary air for combustion. However, with this means, the adjacent flame ports 8 and 8 are completely separated, and when burning in a low oxygen state, the flame causes lifting and causes the generation of CO that is harmful to the human body. Had a problem.

Like the above embodiment, the same parts as those of the prior art are designated by the same reference numerals and detailed description thereof will be omitted, and different parts will be mainly described. To do. In FIG. 4 to FIG. 6, between the flame openings 8 formed along the upper surface longitudinal direction formed by the inner flame opening forming burner body 3, the outer flame opening forming burner body 2 and the flame opening partition plate 4, Two flames in which the flame opening 8 is divided by the central portion 13 to make the opening area about half of the flame opening 8 and the length la of the burner body in the vertical direction is set to about half of the length 1 of the flame opening 8. The mouths 14 and 14 are arranged.

れる。The operation of the gas burner configured as above will be described. The mixture of fuel gas and air, which flows from the pressure equalizing section 7 of the burner main body 1, flows to the upper portion of the burner main body 1 and is ejected from the flame port 8 to form a fire.
At that time, a small flame tip interposed between the large flame tips 8 and 8.
The length of the fire 14a generated in 14 is shorter than that of the fire 8a generated in the large flame port 8 due to the abundance of secondary air supply for combustion. Furthermore, even when burning in a low oxygen state, a long fire 8a and a short fire 14a are arranged next to each other, so that the lifting of the short fire 14a suppresses the lifting of the long fire 8a to prevent lifting and to ensure a stable and uniform fire. Is obtained.

のを防止することができる。EFFECTS OF THE INVENTION As described above, according to the present invention, on the upper surface in the longitudinal direction, between a plurality of flame openings provided in parallel with each other, a flame opening having a small opening area of about half of the flame openings is arranged. It is possible to shorten the fire length of the entire burner by making the fire of the small flame mouth shorter than that of the large flame mouth and abundantly supplying the secondary air for combustion to the flame array of the inner arrangement. Therefore, it is possible to prevent incomplete combustion.

COの発生を防止するものである。Further, the second means of the present invention is such that between a plurality of flame openings provided in parallel on the upper surface in the longitudinal direction, the opening area is about half of this flame opening and the length is the length of the flame opening. By arranging two small flame outlets that are about half the length, by shortening the fire length of the small flame outlet and enriching the supply of secondary air for combustion to the inner flame outlet, The whole fire can be shortened. Therefore, it is possible to prevent incomplete combustion. In addition, the large flame openings and the divided small flame openings are arranged alternately, so that the large flame openings and the small flame openings are adjacent to each other, and when a low oxygen state is burned, the fire of the small flame openings may lift. It is possible to maintain a stable combustion state by suppressing the fire of the adjacent large flame outlets, which is harmful to the human body.
It prevents the generation of CO.
