Therefore, the temperature control probe is fixedly installed on the burner, and soup can be prevented from permeating into the bottom shell of the gas stove from the installation fixing part.
In summary, the gas collecting cavities are arranged on both the outer ring fire and the inner ring fire of the furnace end, and the gas collecting cavities are provided with upper air inlets for primary air to enter and air inlet holes for primary air to enter are arranged on the cavity walls. Therefore, the outer ring fire and the inner ring fire are greatly improved in primary air content, and the inner ring fire and the outer ring fire can ensure sufficient gas combustion, so that ideal combustion efficiency is obtained.
Therefore, the burner of the utility model makes great contribution in the aspect of complementing the primary air content when the outer ring fire and the inner ring fire are combusted, and the whole gas stove has excellent combustion efficiency in the overall consideration. Meanwhile, the convenience of nozzle replacement and air door adjustment is also considered.
Example two:
referring to fig. 1 to 5, when the burner of the present invention is used in a burner, the burner includes the burner 100, the outer ring fire mixing ring 200, the outer ring fire dividing cover 300, and the inner ring fire dividing cover 400 described above.
The outer ring fire gas mixing ring 200 is assembled in the outer ring fire gas mixing cavity 8, the outer ring fire gas collecting cavity 2 and the inner ring fire gas collecting cavity 7. And in order to realize the bearing of the outer ring fire gas mixing ring 200, the part of the outer ring fire gas collecting cavity 2 and the inner ring fire gas collecting cavity 7, which extends out of the top of the substrate 1, is provided with a bearing cavity wall 13 which extends upwards continuously. The bearing cavity wall 13 and the top of the outer ring fire premixing air cavity 8 jointly realize the bearing and installation of the outer ring fire mixing air ring 200.
The outer ring fire distributing cover 300 is assembled on the outer ring fire mixing ring 200, and the inner ring fire distributing cover 400 is assembled on the inner ring fire mixing chamber 11.
In this embodiment, the stove head part extending out of the base plate 1 is used for the top 500 of the stove to be sleeved and the base plate 1 is used for the top 500 of the stove to be attached. After the kitchen range table 500 is attached, the outer ring fire upper air inlet 4 and the inner ring fire upper air inlet 12 upwards exceed the kitchen range table at a proper height, so that the kitchen range table 500 can be positioned on one hand, and on the other hand, the phenomenon that a large amount of primary air enters a gas collecting cavity due to overhigh extension can be avoided.
And the primary air of the outer ring fire enters the outer ring fire gas collecting cavity 2 from the outer ring fire air inlet 5, the outer ring fire upper air inlet 4 between the stove table 500 and the outer ring fire gas mixing ring 200 and is injected into the outer ring fire injection pipe 3.
And the primary air of the inner ring fire enters the inner ring fire gas collecting cavity 7 from the inner ring fire air inlet 14, the inner ring fire upper air inlet 12 between the stove table 500 and the outer ring fire mixing ring 200 and is injected to the inner ring fire injection pipe 10.
Example three:
referring to fig. 1 to 5, when the burner is used in a gas range, the gas range includes the burner 100, the burner 600, and a cooktop 500. The stove table 500 is attached to the base plate 1 of the stove head 100 so that the base plate 1 is attached to the bottom of the stove table 500, and primary air enters between the stove table 500 and the outer fire mixing ring 200.
The foregoing is illustrative of the best mode of embodiments of the utility model only and is not to be construed as limiting the claims. The utility model is not limited to the above embodiments, but its specific structure allows many variations, as long as the variations within the scope of the claims are within the scope of the utility model.
