(57) [Summary] [Purpose] It is easy to manufacture, and the number of parts is reduced to reduce costs. [Structure] For example, in a burner head body formed by casting, the outer wall 6 of the flame port groove 2 is cut to integrally form an annular projection 4 on the lower outer edge of the flame port groove 2. A strip-shaped sleeve flame outlet 5 is formed by the ridge 4 and the flame outlet forming portion 9 of the burner body A.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a stove burner used for a gas table or the like.

[0002]

[Prior art]

 The stove burner used for gas tables, etc. adopts a burner with sleeve flame outlets to increase the load by increasing the load, and for example, due to problems during roasting fire operation or sudden operation. In addition to eliminating blowout, we are also improving fire transfer performance during ignition and preventing lift.

Therefore, in the prior art, since the sleeve flame outlet is formed only by providing the notch in the ridge forming the flame outlet groove of the burner head, the gas flow for the main flame and the sleeve flame Since there was a problem that a stable sleeve fire was not formed due to the interference with the gas flow, the applicant solved this problem and a stable sleeve sleeve can be formed independently regardless of the main flame. Was filed first (Practical application No. 4-10583).

In the device according to the prior application, as shown in FIG. 5, a burner body A'comprises three components, a burner body 8 ', an inner mouthpiece 9', and an outer mouthpiece 10 '. A sleeve fire forming plate 13 'having a sleeve fire hole 12' is superposed on the outer mouthpiece 10 'of the burner body A', with a certain gap communicating with the sleeve fire hole 12 ', and the engaging portion 14'. It is fixed at the ′ ′ and forms an independent sleeve flame outlet 2 ′ that is partitioned from the main flame outlet 1 ′.

[0005]

[Problems to be solved by the device]

 Since the invention according to the above-mentioned prior application is a so-called press burner, the burner body A'is made of sheet metal and has a large number of parts, and moreover, a lot of time and labor are required for manufacturing and assembling each part. It requires a technique, and the burner cap B ′ is made of a stamp, which increases the cost.

An object of the present invention is to provide a stove burner which solves the above problems by improving the invention of the prior application.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, a stove burner of the present invention is provided with a large number of flame outlets on a burner body A having an annular mixing chamber 1 as shown in FIGS. In a stove burner in which a burner head B having radial grooves 2 is freely detachably mounted and a large number of main flame openings 3 are arranged on the peripheral edge, the flame opening of the burner head B is the outer lower edge of the groove 2. Is characterized in that a series of annular convex strips 4 are integrally provided, and a strip-shaped sleeve flame port 5 is formed at the peripheral joint between the annular convex strip 4 and the burner body A.

[0008]

[Action]

 Since the stove burner according to the present invention has the above-mentioned configuration, the corona-shaped sleeve flame b is the main flame at the strip-shaped sleeve flame outlet 5 formed at the peripheral joint between the annular projection 4 of the burner head B and the burner body A. It is formed independently of a.

The annular projection 4 is made by casting, for example, by forming a burner head body having a wall portion 6 on the outer side of the flame port groove 2, and the outer wall portion 6 of the flame port groove 2 of the burner head body is formed. Can be easily formed by cutting the bottom of the ridge 4 while leaving the ridge 4 in the lower part and penetrating the flame port groove 2 in the upper part of the ridge 4.

[0010]

【Example】

 An embodiment of a stove burner according to the present invention will be described below with reference to the drawings.

1 to 4, A is a burner body having an annular mixing chamber 1, a mixing pipe 7 is integrally connected to the annular mixing chamber 1, and a burner head B, which will be described later, is placed in the upper opening. Has a supporting portion 8 and a flame mouth forming portion 9 that forms the sleeve flame mouth 5, and a connecting cylinder 11 into which the supporting cylinder 10 of the burner head B can be inserted and supported in the central portion, and is integrally formed by casting. Has been done.

Reference numeral B is a burner head, which is provided with a large number of flame hole grooves 2 radially on its lower surface by a projection 12, and a series of annular projections 4 is integrally provided on the outer lower edge of the flame hole groove 2. In addition, the support cylinder 10 is provided in the lower central part, and the umbrella 14 having the ventilation hole 13 is provided in the upper part, and they are integrally formed by casting.

The annular ridge 4 of the burner head B has a large number of flame port grooves 2 formed by casting, and a burner head body having a flesh portion 6 outside the flame port grooves 2 is formed. The outer wall portion 6 of the flame port groove 2 is cut while leaving the ridge 4 at the lower part thereof, and the flame port groove 2 is penetrated to the upper part of the ridge line 4 (see FIG. 4).

In FIG. 4, reference numeral 15 denotes a meat portion that is cut and removed when forming the umbrella 13 having the ventilation hole 12.

In the above structure, when the protrusions 12 forming the flame hole groove 2 of the burner head B are placed on the support portion 8 of the burner body A and the burner head B is placed on the burner body A, the burner head B A large number of main flame openings 3 are formed in the flame opening groove 2 of the burner head B, and a strip-shaped sleeve flame is formed below the main flame opening 3 by the annular projection 4 of the burner head B and the flame opening forming portion 9 of the burner body A. The mouth 5 is formed independently.

However, the mixed gas flowing from the annular mixing chamber 1 of the burner main body A into the sleeve flame port 5 through each main flame port 3 is jetted from the sleeve flame port 5 and burned to produce a corona-shaped sleeve. It forms a fire b and fulfills the flame holding function of the main flame a formed at the main flame mouth 3.

[0017]

[Effect of device]

 According to the stove burner of the present invention, since the strip-shaped sleeve flame outlet is independently formed at the peripheral joint between the annular projection of the burner head and the burner body, the function as sleeve fire is sufficiently obtained. It is easy to provide a high load burner for the purpose of improving the throttle performance.

Therefore, the trouble at the time of the operation of the simmering fire, the blowout at the time of the abrupt operation, etc. can be solved, and the usability is improved.

Further, the annular convex strip may be formed by, for example, cutting the outer wall portion of the flame port groove of the cast-molded burner head body by leaving the convex strip at the lower portion thereof and cutting the flame slot at the upper part of the convex strip. Since it can be formed by penetrating, uniform product can be mass-produced, and the cost can be significantly reduced in combination with the decrease in the number of parts.
