Abstract

PURPOSE:To prevent the flame transfer burning section from being affected by mixing pipe, etc. by eliminating a gap between the flame transfer burning section and the mixing pipe. CONSTITUTION:The flame transfer burning section 12 comprising a burner plate A8 and a burner plate B9 is in tight contact with a mixing pipe 11 without a gap (height H). The gas flows from a mixing space 10 to the mixing pipe 11, and then passes the corners on both sides to be divided into the flame transfer burning section 12 and the right-hand and left-hand side main burning sections 13a, 13b to be ejected therefrom. This way, the flame transfer burning section 12 is prevented from being affected by the mixing pipe, and, as the internal pressure is reduced, the faulty burning such as blow off, flame lift, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a gas burner used in gas grills used in homes and the like.

2. Description of the Related Art Gas burners conventionally used in gas grills and the like are shown in FIGS. 4 and 5, and will be described in detail below with reference to the drawings.

The gas burner has burner plate Al and burner plate B2.
It is formed by two pieces, the top and bottom. The gas and air that have flowed into the mixer 4 pass through the mixing tube 5 and flow into the spark combustion section 6, where they are ejected from the flame port and burned. The flame holding plate 3 is fixed to the burner brake (AI) in order to hold the flame during combustion in the transfer combustion section. Note that a gas passage having a height of H is formed between the mixing tube 5 and the spark combustion section. Further, the main combustion sections 7a and 7b extend from side to side following the shifting combustion section 6.

Problem to be Solved by the Invention However, as described above, since the gas passage (height h) exists between the mixing tube 5 and the volatile combustion section 6,
On the other hand, since the gas pressure from the throat 4 and the mixing tube 5 is applied directly, the internal pressure of the shifting combustion section 6 becomes higher than that of the main combustion sections 7a and 7b, making combustion defects such as blow-off and lift more likely to occur. Ta. For this reason, there are problems such as high cost due to providing the flame holding plate 3 and uneven grilling (severe burnt portions) occurring on the cooking surface due to increasing the flame diameter.

Therefore, the present invention provides a gas burner in which the influence of the mixing tube and the like does not affect the combustion section.

Means for Solving the Problems In order to solve the above-mentioned problems, the gas burner of the present invention has the shifting combustion section and the mixing tube in close contact with each other in the upper and lower sides so as to eliminate the gap between them, and the gas passage to the shifting combustion section is separated from the left and right sides. It was molded to be from Ghana.

Function: The above configuration minimizes the gas pressure in the combustion section (
Even if the flame opening is small and there is no flame holding plate, the occurrence of blow-off, lift, etc. can be suppressed. In particular, in the present invention, the central part of the ignition combustion part, which originally has the highest internal pressure, is the farthest from the mixing tube and has the lowest internal pressure.

EXAMPLE Hereinafter, a gas burner in an example of the present invention will be explained with reference to the drawings.

As shown in FIG. 2, the main combustion parts 13a, 13b have a large number of main flame ports on the left and right, and the main combustion parts 13a, 13b are
A shifting combustion section 1 having multiple flame ports between the connected corners
2, and a mixer 10 and a mixing pipe 11 are located behind the spark combustion section 12.

As shown in FIG. 1, there is no gap (height H) between the shifting combustion part 12 formed by burner plate A8 and burner plate B9 and the mixing tube 11, and they are in close contact with each other. The fuel then flows into the mixing tube 11, passes through the left and right corner portions 14a and 14b, and is divided into a spark combustion section 12 and left and right main combustion sections 13a and 13b, where it flows and is ejected.

As shown in FIG. 3, the grill has a box body formed by a grill case urchin 15 and a grill case cover 16, and a gas burner 20 of the present invention is located inside the grill chamber. A grill plate 18 and a grill M419 are provided below.

Effects of the Invention As described above, the gas burner of the present invention provides the following effects.

(1) By eliminating the gap between the spark combustion part and the mixing tube, the influence of the mixing pipe on the spark combustion part is eliminated, and the internal pressure is reduced. Poor combustion in lifts, etc. can be prevented, costs can be reduced, and cooking performance can be improved.

(2) There is no gap between the flame transfer combustion part and the mixing tube, and the distance from the throat and mixing tube is large, so the rise of gas salts in the throat and mixing tube is reduced, suppressing the occurrence of flashbacks, etc. I can do it.

Claims (1)

[Claims] A main combustion part that is made up of two upper and lower metal plates and has a large number of flame ports on the left and right sides, and a shifting combustion part that has a plurality of flame ports between the left and right corners that connect the amphibatic combustion part; A throat and a mixing pipe are each arranged in a U-shape behind the spark combustion section, and are brought into close contact with each other vertically to eliminate a gap between the spark combustion section and the mixing tube, thereby providing a gas passage to the spark combustion section. A gas burner that is molded so that it can only be opened from the left and right corners.
