例2という)がある。The stove burner such as a gas table has L on the burner head.
Since it has a structure in which the bent mixing pipes are connected to each other, a nonuniform flow occurs in the mixed gas flowing through the bent portions of the mixing pipes, and a uniform distribution in the burner head cannot be obtained. Therefore, various rectifying means have been conventionally used to rectify the air-fuel mixture and obtain a uniform distribution in the burner head. For example, as shown in FIG.
In the stove burner in which the L-shaped mixing tube B'is connected to the burner head A ', the tip side 6'is extended from the bending portion 1'of the mixing tube B'and the rectification distance l of the air-fuel mixture is increased. To correct the uneven flow of the air-fuel mixture (hereinafter referred to as Conventional Example 1), or as shown in FIG. 8, connect a burner head A'to an L-shaped mixing tube B '. In the stove burner thus constituted, a recess 9'for buffering the dynamic pressure of the air-fuel mixture is provided on the lower surface of the burner cap 5'of the burner head A ', and mixing is performed by the correction space formed by the dynamic pressure buffer recess 9'. There is one that corrects the drift of air (hereinafter referred to as Conventional Example 2).
また、混合気通路内の曲がり部に、複数の孔を並設
し、かつ各孔の周囲に混合気が折り返される側の上方に
突出する案内羽根を有する均圧板を設置するもの(以下
従来例3という)がある(特公昭64-10729号参照)。Further, a plurality of holes are arranged in parallel in the bent portion in the air-fuel mixture passage, and a pressure equalizing plate having guide vanes protruding upward on the side where the air-fuel mixture is folded back is installed around each hole (hereinafter referred to as a conventional example. 3) (see Japanese Examined Patent Publication No. 64-10729).
上記従来の技術における従来例1にあっては、混合管

ナが大型化するという問題点があった。In Conventional Example 1 of the above-mentioned conventional technique, the tip side 6'is only vertically extended from the bent portion 1'of the mixing tube B ', and therefore, a considerably long rectification distance l is required for rectifying the air-fuel mixture. 6'from the bend 1'of the mixing tube B'to require the
However, there is a problem that it cannot be used when there is a restriction on the mounting relationship due to its length, and in the conventional example 2, the air-fuel mixture is rectified by the dynamic pressure cushion in the burner head A '. Is a large dynamic pressure buffering recess 9 '
However, there is a problem that the burner becomes large in size because it is necessary to provide a sufficient correction space.
従来例3にあっては均圧板の構成が複雑で、その均圧
板を混合気通路内の曲がり部の所定位置に設置すること
は容易ではないとう問題点があった。In the conventional example 3, the structure of the pressure equalizing plate is complicated, and it is not easy to install the pressure equalizing plate at a predetermined position of the curved portion in the mixture passage.

均等化を図ったこんろバーナの提供を目的としている。In view of the above problems of the prior art, the present invention integrally forms a mixed-flow bias correction convex portion on the large curvature side of the bent portion of the mixing pipe, and effects the mixed-flow bias of the mixed pressure by the dynamic pressure cushion. The object of the present invention is to provide a stove burner in which the distribution of the air-fuel mixture in the burner head is made uniform by uniformly correcting and rectifying the burner flame to make the burner flame uniform.

Therefore, the convex portion having no dimensional error can be easily formed by press working or the like to effectively obtain the drift correction effect of claim 1.
According to the third aspect of the invention, since the convex portion that corrects the uneven flow of the air-fuel mixture is integrally formed with the burner body of the burner head on the upper side of the bending portion of the mixing tube where the curvature is large, special processing and mounting are required. Thus, the convex portion can be formed without any effect, and the drift correction effect of the first aspect can be effectively obtained.

ーナが形成できるようになっている。Embodiment 1 In Embodiment 1 shown in FIG. 1 and FIG. 2, A is a burner head, a burner body having an inclined smooth surface 3a at the peripheral edge of the upper surface opening and a mixing pipe connection port 3b at the lower part. 3 and a burner cap 5 in which a plurality of slit-shaped flame hole grooves 5a forming a flame hole 4 in close contact with the slanted smooth surface 3a of the burner body 3 at the outer peripheral edge of the lower surface are radially formed. By placing the burner cap 5 on the body 3 and bringing the slit-shaped flame hole groove 5a of the burner cap 5 into close contact with the slanted smooth surface 3a of the burner body 3, the peripheral edge between the burner body 3 and the burner cap 5 is made. A burner head A having a large number of flame ports 4 in a radial shape is formed, and these can be easily separated by removing the burner cap 5 from the burner body 3. Reference numeral B denotes a mixing tube, which is bent in an L shape, and an end 6a on the tip side 6 thereof is connected to a connection port 3b of the burner body 3 of the burner head A so that a stove burner can be formed.

一体に形成せしめている。Reference numeral 1 is a bent portion of the mixing tube B, and an upper portion of the curved wall 1a on the front side where the bent portion 1 has a large curvature, that is, a part of the base portion of the tip side 6 is recessed from the outside to the inside. An inwardly protruding convex portion 2 for correcting the drift is formed integrally with the curved wall 1a.

ナ火炎は均一化される。Therefore, in the first embodiment, when the air-fuel mixture from the proximal end side 7 of the L-shaped bent mixing tube B to the distal end side 6 via the bending part 1 flows through the bending part 1, The air-fuel mixture flowing along the front curved wall 1a having a large curvature of the bent portion 1 hits the convex portion 2 at the upper portion thereof and the flow is slightly displaced to the rear side having a small curvature, which is caused by the bent portion 1 in the dynamic pressure cushion. Since the uneven flow of the air-fuel mixture is destroyed and corrected, and the flow is rectified and directed directly upward (see arrow a in FIG. 1), the air-fuel mixture reaching the mixing chamber 8 of the burner head A is evenly distributed in each part, The burner flame formed in the flame port 4 on the periphery of the head A is made uniform.

The convex portion 2 for correcting the drift of the air-fuel mixture is integrally formed with the burner body 3 of the burner head A on the upper side of the bending portion 1 of the mixing tube B on the large curvature side.
The drawing shows a projecting portion 2 which is formed integrally with the casting burner body 3 of the burner head A in the vicinity of the connection port 3b so as to project inward. FIGS. 5 and 6 show the sheet metal of the burner head A. The burner body 3 is integrally formed by protruding the convex portion 2 inwardly near the caulking connection port 3b.
In the second embodiment, since the convex portion 2 is formed in advance on the burner body of the burner head A, the mixing pipe is simply connected by maintaining the burner head A and the mixing pipe B in a fixed positional relationship. The convex portion 2 for correcting the drift can be formed in the upper portion of the curved portion 1 of B having a large curvature, and there is a slight gap between the curved portion 1 and the convex portion 2 as shown in the drawing. The tip portion 6 of the mixing tube B is shortened so that the bent portion 1 and the convex portion 2 are in the same relational positions as in the first embodiment, but in any case, the action is the same as in the first embodiment. Since the other structures are the same as those in the first embodiment, the same parts are designated by the same reference numerals, and their description will be omitted.
