When it is necessary to adjust the size of the air supply gap 23, the user can hold the adjustment dial 73 to rotate the adjustment member 7.
10-12, The burner assembly of the upper air intake type gas cooker in the embodiment 3 is implemented on the principle that the burner assembly of the upper air intake type gas cooker is provided with two air supply channels for providing secondary air for the outer ring burner 3, so that the size of the air supply gap 23 can be adjusted, and the flame position generated by the outer ring burner 3 can be adjusted;
When the flame of the outer ring cooking stove 3 is required to be deflected outwards, the air supply gap 23 can be enlarged, so that the supply amount of secondary air outside the outer ring cooking stove 3 is increased, and the flame generated by the outer ring cooking stove 3 is deflected outwards;
when the flame of the outer ring burner 3 needs to be deflected to the inside, the air supply gap 23 may be adjusted to be small so that the supply amount of secondary air at the outer side of the outer ring burner 3 is reduced, and the relative supply ratio of secondary air at the inner side of the opposite outer ring burner 3 is increased so that the flame generated by the outer ring burner 3 is deflected to the inside.
Example 4
The gas cooker in this embodiment includes the burner assembly of the upper air intake gas cooker in embodiment 1.
Example 5
The gas cooker in this embodiment includes the burner assembly of the upper air intake gas cooker in embodiment 2.
Example 6
The gas cooker in this embodiment includes the burner assembly of the upper air intake gas cooker in embodiment 3.
The above embodiments are not intended to limit the scope of the application, so that the equivalent changes of the structure, shape and principle of the application are covered by the scope of the application.
