Abstract

PURPOSE:To easily cut a burner body at its central part, to enable the use of the burner body as a small burner after caulking, and to reduce a mould cost, by a method wherein a gas burner comprises a narrow part, which is connected to two mixing pipe parts, integrally formed, and can be cut, a burner body with a narrow part, which is formed by throttling the mixing pipe parts, and a flame transfer plate with which a burner port in the narrow part is covered. CONSTITUTION:When a burner body 6 is used as a one-piece burner, a flame transfer plate 16 is mounted on a narrow part 15 at a central part. When the burner body 6 is used as two burners, mixing pipe parts 7 and 7a, processed as a single part, are cut at a narrow part 10, and the cut ends are closed. Meanwhile, a burner port part 8, processed as a single part, is cut at the narrow part 15, and the cut ends are closed. The individual cut burner port parts 8 are joined with the mixing pipe parts 7 and 7a for completion. In this case, the flame plate 16 is not needed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a gas burner used in a gas combustion device.

2. Description of the Related Art In recent years, gas burners have become popular as a part of gas appliances as they become smaller and more efficient.

Hereinafter, an example of the conventional gas burner mentioned above will be described with reference to the drawings.

FIGS. 2 and 3 show a top view and a front view of a conventional gas burner. Reference numeral 1 denotes a burner main body, which has a gas suction port 2.2a that opens oppositely to each other on the left and right sides of the center, and a mixing pipe section 3.3a that extends from the gas suction port to both sides. 3.3a at both left and right ends, and has a flame hole portion 5 having a large number of slit-shaped flame holes 4 on the upper surface.

Air is sucked through the gas suction port 2.2a by the ejector effect of the gas ejected from a nozzle (not shown) facing the gas suction port 2.2a, and the gas and this air are mixed in the pipe section 3.3a. The mixture is mixed and ejected from the flame hole 4, ignited, and combusted. Conventionally, the burner main body 1 and the flame hole portion 5 have been fabricated as separate parts, or they have been fabricated as a single piece by pressing two sheets of metal and gluing them together.

'The problem that A Ming is trying to solve This burner body 1 has gas: suction port 2.2a, mixed pipe part 3
．． 3a each has 2 t″L ([1u increased capacity - [d,
Although this is a dog burner, it has the functional parts equivalent to two burners, so standardization has been requested so that it can be used as two burners for Kogane 1I-1.

However, with the above configuration, cutting and caulking cannot be performed at the center of the burner body 1, and the burner body 1 cannot be used as a small gas burner or two pieces of wood.

The present invention solves the above problems and can be used as a single gas burner with two gas inlets on the left and right sides of the center, and can be easily cut into two small gas burners by cutting at the center and caulking. To provide a gas burner that can be used separately.

Means for Solving the ProblemsIn order to solve the problems, Subarna of the present invention is as follows:
A cuttable f-length publication made by drying the central part of the elongated flame hole connected to two integrally formed mixing pipe parts [1 width J$
It is connected to this thin 11ih and 7i [11122
Burner 11: The body of the burner 11, which lights up the entire narrow part of the mixing pipe part, is formed by making dead wood, and the flame holes located on the left and right sides of the narrow part It is equipped with a flame transfer plate that extends through the flame holes in the narrow part so that flame transfer can be carried out easily.

Effects of the present invention With the above-described configuration, if a one-wood burner is cut at the narrow part in the center and caulked, needle traces can be used for a small two-wood burner, and molding is not required much. Type 2 burners can be maintained at f2J'' without being overlaid.

EXAMPLE A gas burner according to an example of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a gas burner in one embodiment of the present invention. In FIG. 1, reference numeral 6 denotes a burner body consisting of two mixing tube sections 7.7a and one flame hole section 8. The two mixing pipe parts 7.7a have two gas suction ports 9.9a which are opened opposite to each other in the central part, and are integrated at the central part of the gas passage, and all of the central part is made of active water. Narrow width part 10
form a gas passage. Further, this mixing tube portion 7, Y&, is a press part (sheet metal) of the left t] and f, t, which is folded in half and the entire inner circumference 11 and outer circumference 12 are caulked.

IJ! The Li flame hole part 8 has a large number of slit-like flame holes 13 on the elongated upper surface, and has a flame hole 14 in the center that can be easily cut and caulked with a narrow width r<W 15.
k is formed. The flame hole part 8 has its lower ati opening edge inserted into the upper surface opening of the mixing pipe part 7.7&, both ends of which are swaged, and the contact α part is entirely f8f. Reference numeral 16 is a multi-plate flame holder, which is attached to the 1st width part 15 of the flame hole part 8 by screwing it in, and the flame is transferred to the flame hole 13 on the left H.

In the embodiment described above, when the burner body 6 is used as a single wood burner, a fire plate 16 is provided in the narrow part 15 at the center. However, when this burner main body 6 is used as a two-wood burner, the mixing tube part 7.7a processed as a 4-i insect body part is cut with its narrow part 10 (and its cut end is On the other hand, the flame hole part 8, which was similarly processed as a single + component, is cut at its narrow width part 15, and the cuts are joined.Then, these cut and processed individual flame holes are The process is completed by joining the part 8.8 and the mixing pipe part 7.7a.At this time, the transfer plate 16 is unnecessary.

The gas burner of the present invention, which has a configuration that exceeds the effects of the invention, can be used as a single piece of wood, or can be easily cut from the center and used as a small burner after crimping. Therefore, mold costs can be reduced and costs can be reduced.
