Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a gas burner mainly used as a stove burner.

(Prior art) Conventionally, as this type of burner, for example, JP-A-58-
As seen in Publication No. 123012, the burner top on the burner body is provided with an inner hole for secondary air in the center, an inner flame hole on the outer periphery, and a space above the inner hole. It is known that the burner top is provided with opposing lids and that the upper surface of the burner top is configured to prevent broth from flowing toward the inner opening.

(Problems to be solved by the invention) However, since the lid body has a cylindrical part on the bottom surface and an air hole in the cylindrical part, its structure is complicated and it is difficult to clean. There is a problem with this.

(Means for Solving the Problems) The purpose of the present invention is to obtain a burner free of such inconveniences.The burner top on the burner body has an inner hole for secondary air in the center, The burner top has an inner flame hole on its outer periphery, and a lid that faces above the inner opening with a gap therebetween, and is configured to prevent broth from flowing over the upper surface of the burner top toward the inner opening. In the burner top, a plurality of legs extending upwardly surrounding the upper end of the inner opening are integrally formed, and the lid body is supported from the lower surface by the legs, and The inner flame hole is opened from each leg to the outer surface thereof, and the space between the legs serves as an air passage communicating with the inner opening.

(Example) An example of implementing the present invention will be explained with reference to attached drawings. In the drawings, 1 indicates the burner main body, 2 indicates the burner top on the main body 1, and 3 indicates the outer flame holes arranged in an annular manner around the outer periphery.
and an inner flame hole 5 on the outer periphery thereof, and a lid 6 facing above the inner opening 4 with a gap therebetween. In the drawings, 7 indicates a secondary air passage in the center of the main body 1, and 8 indicates a mixing chamber at its outer periphery.

The burner top 2 is provided with an annular convex portion surrounding the upper end opening of the opening 4 to prevent boiling liquid from falling onto the upper surface of the burner top 2 from the opening side. Then, a plurality of circumferential legs 10 extending upward from the convex portion 9 are integrally formed,
The lid body 6 is supported by the legs 10 from below, and the inner flame holes 5 are opened from inside each leg 10 to the outer surface 10a thereof.

More specifically, in the illustrated example, the convex portion 9 as a whole extends upward in a generally truncated conical shape, and an air passageway is provided in the extended portion that opens upward and communicates with the inner opening. 11 are arranged in four pieces on the circumference, and the remaining parts are formed in each leg part 10, so that each leg part 10 has an outer surface 10a that is inclined upward. It is assumed that the lid body 6 is fitted and supported by the leg portions 10 at a flange 6a that bends and extends downward on the outer periphery.

In the case shown in FIG. 3, the inner flame hole 5 is oriented slightly upward. For this reason, if the top surface of the lid body 6 cannot be covered due to the design, there is a risk that the boiling liquid that falls directly onto the top surface of the inner flame hole 5 may infiltrate the inner flame hole 5, as shown in FIG. When the hole 5 is directed downward, such inconvenience can be eliminated.

(Function) Thus, when assembling the burner body 1
It is simple enough to apply the burner top 2 and then the lid 6 on top of the burner top 2 and then the lid 6 in sequence, and if boiling over occurs during use, for example as shown in FIG. The boiling liquid a acting from the outer periphery of the burner top 2 below the outer edge of the burner top 2
is guided to the outer periphery of the leg through the upper surface of the outer periphery of the leg, thus preventing the broth from dripping into the inner opening 4, and the inner flame hole 5 opens from inside each leg to the outer surface of the leg. Infiltration of boiling liquid that falls directly onto the upper part of the inner flame hole 5 can also be prevented as much as possible.

(Effects of the invention) As described above, according to the invention, a plurality of legs extending upwardly and surrounding the upper end opening of the inner opening are integrally formed on the burner top, and the lid body is attached to the lid body. The legs are supported from the lower surface, and the inner flame hole is opened from each leg to the outer surface, and the space between the legs is used as an air passage communicating with the inner opening. Compared to the conventional type having an air hole in the cylindrical part, the structure is not only simpler and easier to clean, but also when the lid body is removed from the leg part, the air hole is formed between the leg parts. The upper surface of the air passage is opened, which makes cleaning this area easier.
