Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas stove burner for a gas cooker.

[0002]

2. Description of the Related Art In a conventional stove burner of this type, as shown in FIGS. 4 and 5, the burner cap 4 and the burner head 1 are fitted and positioned downward from the main flame hole mounting portion 11 of the burner head. The burner cap which is composed of both sides of the press-formed concave ignition flame hole mounting surface 15 and which is fitted and mounted in the positioning recess 16 of the burner head is also shown in FIG.
As shown in (a) and (b), positioning convex projections 17 are provided below both sides of the ignition flame hole, and the ignition flame hole 5 of the burner cap, the discharge projection 13, and the thermocouple flame hole 7 are attached to the main body. Further, it is configured to be mounted and mounted so as to correspond to the positions of the ignition electrode 6 and the thermocouple.

[0003]

However, in the structure shown in FIG. 6, since the fitting projection of the burner cap matches the mounting surface shape of the burner head, the projection shape becomes complicated and the moldability is poor. Had. Further, despite the complicated shape, the size is regulated for positioning with the burner head, and there is a problem that moldability is poor. Further, there is a problem that during processing, the protrusions are damaged, positioning becomes unstable, and ignition failure and extinguishment cannot be performed to ensure normal operation of the safety device. Further, since the positioning recess of the press-molded burner head has a deep drawing shape from the main flame hole mounting portion, there is a problem that the press-molding is difficult and the dimension is difficult.

An object of the present invention is to solve the above problems and an object of the present invention is to provide a stove burner which can be reliably positioned and has a good moldability.

[0005]

In order to achieve the above object, a stove burner according to the present invention has a radial main flame hole on its outer circumference, and is fitted and positioned with a burner head inside the main flame hole. And a burner head press-molded with a fitting opening hole for the positioning projection of the burner cap provided inside the main flame hole mounting surface.

[0006]

According to the present invention, since the fitting opening hole is provided on the main flame hole mounting surface of the burner head according to the above-mentioned structure, the shape of the throttle portion of the ignition flame hole portion of the burner head becomes shallow, and the press formability is also improved. improves. In addition, since the fitting opening of the burner head is also easily drilled to improve the dimensional accuracy, the fitting accuracy of the burner cap and burner head is improved, and the burner cap ignition flame hole, discharge projection, and thermocouple. It is possible to obtain a stove burner having good ignition performance and extinguishing safety device performance by mounting and mounting the flame electrode, the ignition electrode attached to the main body, and the thermocouple so as to be in normal positions.

[0007]

The present invention will be described below.

A feature of the present invention is that by providing a fitting opening hole on the main flame hole mounting surface of the burner head, punching at the time of press working can be done simultaneously with other opening holes. In addition, the fitting protrusion of the burner cap is also possible with a small protrusion from the main flame hole surface, and the protrusion shape can be reinforced with a simple shape according to the opening shape of the burner head, and at the same time the dimensional accuracy is improved. The fitting accuracy with the burner head is also improved, and the ignition flame hole of the burner cap, the discharge projection, and the thermocouple flame hole and the ignition electrode and thermocouple attached to the main body are placed and mounted so that they are in normal positions. It was a stovetop burner.

A specific embodiment will be described below with reference to the drawings. 1, 2 and 3 (a) and 3 (b), 1
Is a press-molded burner head, and the gas supplied from the nozzle 2 is mixed with air in the mixing tube 3 and ignited by the ignition electrode 6 in the ignition flame hole portion 5 formed by the burner cap 4 and the burner head 1. Then, the flame is transferred to the adjacent thermocouple flame hole 7 and transferred to the entire circumference of the main flame hole 9 through the flame transfer flame hole 8.

In the above structure, since the fitting opening hole 10 of the burner cap is provided on the same surface as the main flame hole mounting surface 11, the fitting positioning projection 12 of the burner cap is also simple, and the moldability, The workability is improved, the moldability and workability of the burner flame hole mounting surface 18 of the burner head are improved, the fitting property with the burner cap is improved, and the ignition flame hole and the thermocouple flame hole are improved. Stabilize. Further, the fitting positioning is stable, the rattling of the burner cap and the burner head is reduced, the positions of the ignition flame hole, the discharge projection 13 and the ignition electrode, and the positions of the thermocouple flame hole and the thermocouple are stable, which is excellent. It has the effect of ensuring excellent ignition performance and extinguishing safety performance.

Even if a plurality of fitting holes for the burner head are provided, the fitting accuracy is further improved, and the same effect can be obtained. The same effect can be obtained even if the fitting opening hole of the burner head is provided not only on the main flame hole mounting surface but also at the position that also serves as the mixed gas supply port 14.

[0012]

As described above, according to the present invention, since the fitting opening hole is provided on the main flame hole mounting surface of the press-molded burner head, the shape of the narrowing portion of the ignition flame hole portion of the burner head is shallow. Therefore, the press formability is also improved. In addition, since the fitting opening of the burner head is also easily drilled to improve the dimensional accuracy, the fitting accuracy of the burner cap and burner head is improved, and the burner cap ignition flame hole, discharge projection, and thermocouple. It provides a stove burner with good ignition performance and extinguishing safety device performance, which is mounted and installed so that the flame hole and the ignition electrode and thermocouple attached to the main body are in the normal position, which is extremely advantageous in practical use. is there.
