Description

Dual Flame Burner Structure of Gas Instrument

The present invention relates to a double flame burner structure of a gas machine, and more particularly, to a double flame burner structure of a gas machine to increase the thermal efficiency by making it easy to generate a secondary flame after the primary flame. .

In general, burners used in various gas appliances have a mixing pipe formed at a lower portion of the burner, and are supplied through a fuel injection nozzle connected to the air sucked through an air inlet formed at the center of the lower portion of the mixing pipe and an end of the gas supply pipe. The gas to be mixed is mixed in the mixing pipe and ejected through the flame holes of the burner.

Referring to the structure of a conventional burner for a gas appliance in detail, as shown in the accompanying drawings in Figure 1, the body portion 10 and the fire to generate a large division, the upper portion of the body portion 10 It consists of a cap 20 to be seated.

The body portion 10 has a circular, venturi hole 11 for discharging the gas mixed with the air from the lower portion in a central position is formed through. In addition, a plurality of first flame portions 12 are formed along the circumferential direction on the outer circumferential surface of the body portion 10. The first flame portion 12 has a groove shape.

In addition, the body portion 10 has four ribs 13 forming a triangular shape protruding and formed, and the air guide member inclined in one direction while the vent hole 14 is formed on the inner surface of the rib 13. 15 are formed, respectively.

In addition, a four-way passage 16 is formed between the ribs 13, and the passage 16 serves as a flow path through which the supplied gas flows. In addition, a second flame portion 17 is formed on the upper surface of each of the ribs 13, and the second flame portion 17 also has a groove shape.

In addition, at one side of the circumferential surface of the body portion 10, a mounting groove 18 for mounting the spark plug (not shown) to be ignitable is formed.

On the other hand, the cap portion 20 seated on the upper portion of the body portion 10 is formed with through-holes 21 of approximately triangular shape to match the ribs 13 forming the triangular shape, respectively, so that the flame is discharged. .

Figure 2 is a cross-sectional view showing a coupling structure of a conventional burner, the gas chamber 30 is provided in the lower portion of the burner body portion 10. The air mixed gas introduced through the venturi ball 11 penetrated and formed in the center of the body portion 10 from the gas chamber 30 hits the inner surface of the cap portion 20 at the upper portion of the body portion 10, and then the body Guided to the outer portion through each passage 16 of the portion 10 is discharged through the first flame portion 12 and the second flame portion 17, respectively, so that the flame is outside the circumferential surface of the cap portion 20 Through the through-hole 21 to form a triangular shape and will be a double flame.

Of course, the first flame portion 12 has a flame formed over the entire circumferential direction of the body portion 10, the second flame portion 17 is a portion of the flame is formed in four places.

In the conventional burner structure, the flame formed through the first flame portion 12 faces outward as shown by the arrow in FIG. 2, and the flame formed through the second flame portion 17 faces inward. Therefore, the flame of the first flame portion 12, which is primarily formed, is not quickly transferred to the second flame portion 17.

This is because the flow direction of the gas for forming the flame is relatively far from the first flame portion 12 and the second flame portion 17, so that secondary flame formation is difficult. Therefore, the heat distribution in the burner is not formed uniformly, a problem occurs that the thermal efficiency of the gas equipment is lowered.

In addition, in order to improve the ignition to the second flame portion as described above, a plurality of radial cuts may be formed on the circumferential surface of the cap part, but in this case, the formation of the cut part may cause deformation during manufacturing of the cap part. In addition, in the manufacture of the cap portion, when the enameled surface, the incision was sometimes clogged, and did not exert a special effect.

Accordingly, the present invention is designed to solve the conventional problems as described above, so that the transition to the secondary flame is made quickly after the primary flame is generated, thereby increasing the thermal efficiency, double flame burner for gas appliances The purpose of the design is to provide a structure.
