Description of the Related Art A conventional gas burner of this type will be explained with reference to FIGS. 3 to 6. 1 is the burner body, which consists of a pair of outer plates (also referred to as the burner body for forming the outer flame port) 2.2 and a U-shaped inner plate (
It consists of a burner body (also referred to as a burner body for forming an inner burner port) 3, and a pair of burner port partition plates 4 positioned and sandwiched between the outer plate 2.2 and the inner plate 3. This burner body l has a primary air suction part 5, a mixing pipe part 6, a pressure equalizing part 7, and a large number of slit-shaped flame ports 8, which are arranged along the longitudinal direction of the burner body 1. A large number of them are arranged side by side to form a group with the heating parts 9 interposed alternately, and the groups are lined up in parallel to form a reflux area 10 between them. In order to form the suction part 5, the mixing pipe part 6, and the pressure equalizing part 7, the outer plate 2.2 is press-formed with half-divided concave parts at opposing positions, and furthermore, the flame outlet 8 and the flame outlet hot part 9 are press-formed. In order to form the concave portion 2a and the convex portion 2b, the concave portion 2a and the convex portion 2b are press-formed. Further, the inner plate 3 and the outer plate 2.2 are press-formed with concave portions 3as and convex portions 3b in order to form a flame port 8 on the upper surface.

するノズルである。To assemble this burner body l, one outer plate 2, one burner opening partition plate 4, and inner plate 3 are joined by aligning the concave part 3a and the convex part 3b with the concave part 2a and convex part 2b of the outer plate 2, respectively. Then, the other flame opening partition plate 4 and the other outer plate 2 are joined, and finally the outer circumference and inner circumference of the outer plate 2.2 are welded, and the convex parts 2b, 3b and the flame opening partition plate 4 are spot welded. The flame ports 8 are formed independently. When the burner main body 1 is assembled, although the lower ends of the pair of flame port partition plates 4.4 are slightly bent from the center, a gap 11 is formed in the pressure equalizing portion 7 over the entire length. 12 is a nozzle that spouts gas.

着火されて燃焼するのである。Then, the gas ejected from the nozzle causes primary air for combustion to be sucked in from the suction part 5 by the ejector action, and is mixed in the mixing pipe part 6. Furthermore, the air-fuel mixture is pressure-equalized in the pressure equalization part 7, and is separated from the flame opening partition. It is divided by the plate 4 and flows to the outer and inner flame ports 8,
It ignites and burns.

Since secondary air for combustion is not supplied to the inner flame port 8, the burner body l
There was a problem that there was a lack of secondary air in the inner flame port 8, and the length of the flame was long (which resulted in incomplete combustion, causing the generation of CO that was harmful to the human body.) One way to do this is to shorten the length of the flame ports 8 in the longitudinal direction and increase the gap between adjacent flame ports 8 to ensure a sufficient supply of secondary air for combustion. In this method, the adjacent flame ports 8 and 8 are completely separated, and during combustion in low oxygen conditions, the flame lifts, causing the generation of CO that is harmful to the human body.

、異なる部分を中心に説明する。EXAMPLE Hereinafter, a gas burner according to an example of the present invention will be described with reference to the drawings. Note that the same parts as those in the prior art shown in FIGS. 3 to 6 are given the same reference numerals, detailed explanations are omitted, and different parts will be mainly explained.

持され、炎口8を仕切る炎口仕切板4とでバーナ本体1
の長手方向の上面に複数列炎口8が形成される。In Fig. 1 and Fig. 2, the burner main body 3 for forming the inner flame port
The burner body 1 is composed of a burner body 2 for forming an outer flame mouth, and a flame mouth partition plate 4 which is sandwiched between these two burner bodies and partitions a flame mouth 8.
A plurality of rows of burner ports 8 are formed on the upper surface in the longitudinal direction.
この炎口8の群はその短辺方向の幅が他の炎口8の約半
分の寸法にした炎口8aを、ひとつおきに配列している
。したがって、炎口8aは炎口8の開口面積の約半分に
設定している。In this group of burner ports 8, burner ports 8a whose width in the short side direction is about half that of the other burner ports 8 are arranged every other burner port. Therefore, the burner port 8a is set to approximately half the opening area of the burner port 8.

いても、長い火炎12と短い火炎12aとが隣り合せに
配列されているので、短い火炎12aのリフティングを
、長い火炎12がおさえるのである。In the above embodiment, the gas is ejected from the nozzle, mixed with the primary air for combustion sucked from the suction part 5 and gasified in the mixing pipe part 6, and further pressure-equalized in the pressure equalization part 7, so that the air-fuel mixture is mixed into each flame. It is ejected from the port 8.8a and burns. Then, the supply of secondary air for combustion is more abundant in the small flame port 8a than in the large flame port 8, and the flame 12a is shorter than the flame 12 of the other flame ports 8. Furthermore, even during combustion under low oxygen conditions, the long flames 12 and the short flames 12a are arranged next to each other, so the long flames 12 suppress the lifting of the short flames 12a.

焼になるのを防止することができる。Effects of the Invention As described above, the present invention has a large number of flame holes provided in parallel on the upper surface in the longitudinal direction, and small flame holes whose width in the short side direction of the flame holes is approximately halved are arranged every other one. Therefore, the flame length of the small flame port can be made shorter than that of the large flame hole (this allows the supply of secondary combustion air to the inner array of flame holes to be abundant, and the flame length of the entire burner can be shortened. , it is possible to prevent incomplete combustion.
さらに、大きな炎口と小さな炎口が交互に配列されてい

有害なCOの発生を防止できる。In addition, the alternating arrangement of large and small flame ports allows the large and small flame ports to sit next to each other, which prevents short flames from attempting to lift during combustion in low oxygen conditions. By suppressing the long flame, a stable combustion state can be maintained and the generation of CO, which is harmful to the human body, can be prevented.
