Description

[Detailed description of the invention] The present invention relates to the structure of the auxiliary flame of a gas burner. An odor-catching lower is provided below the main flame port 6 of the burner body 3, and the gas distribution chamber 9 in the burner body 3 and the odor-catching lower are connected. This relates to a gas burner that communicates with an odor-catching passage 12 having a substantially inverted U-shaped cross section, and the object of the present invention is that since the odor-catching passage is in an inverted U-shape, there is To provide a gas burner without the risk of boiling liquid flowing in.

The present invention will be explained in detail below using examples.

The annular burner body 3 is formed by placing a burner top 11 on a burner body 10.

A gas distribution chamber 9 is provided in the burner body 3 in an annular manner over substantially the entire circumference, and the mixing tube 1 below the burner body 3 is communicated with the gas distribution chamber 9.

On the outer periphery of the burner top 11 of the burner body 3, a large number of main flame ports 6 serving as outer flame ports are provided in the circumferential direction, and on the inner periphery, a large number of main flame ports 6 serving as inner flame ports are provided in the circumferential direction. The main flame port 6 communicates with the inside of the gas distribution chamber 9.

Odor-catching passages 12 each having a substantially inverted U-shaped cross section are provided on the outer and inner circumferential sides between the burner top 11 and the burner body 10 of the burner body 3, and the odor-catching passages 12 on the outer circumferential side are provided with The surface is provided with odor trapping lowers for external flames, and the inner peripheral surface of the odor trapping passage 12 on the inner peripheral side is provided with odor trapping lowers for internal flames. The odor lower communicates with the gas distribution chamber 9.

When the mixed gas mixed with primary air is supplied from the mixing tube 1 into the gas distribution chamber 9 of the burner body 3, the mixed gas is ejected from the main flame port 6 for the outer flame and the inner flame and is captured. A mixed gas is ejected from the odor trapping lower for the outer flame and inner flame through the odor path 12.

At this time, when the ignition device ignites, a main flame is formed at each main flame port 6, and an auxiliary flame is formed at the odor-catching lower, thereby continuing combustion in a stable state.

As described above, in the present invention, the gas distribution chamber in the burner body and the odor trapping port are communicated through an odor trapping path having a substantially inverted U-shaped cross section.
The boiling liquid does not flow into the interior through the odor-catching port, and a stable combustion condition is always achieved without the thin odor-catching port becoming clogged.
