Top air burner

Abstract

The invention discloses an upward air intake burner, which includes: an inner ring fire cover, an outer ring fire cover, and a gas distribution plate; the gas distribution plate includes: an outer ring ejector tube, an inner ring ejector tube, an outer ring chamber, Inner ring chamber; the outer ring injection tube is connected to the outer ring chamber, the inner ring injection tube is connected to the inner ring chamber, the outer ring chamber is used to supply air for the outer ring fire cover, and the inner ring chamber is used for The inner ring fire cover supplies air; the outer ring chamber is a ring structure, and the inner ring chamber is located inside the ring structure of the outer ring chamber, and the inner ring injection pipe is intersected with the middle section of the outer ring chamber, and the outer ring chamber is along the The direction of the intake air in the outer ring chamber tapers. Through the staggered arrangement of the inner ring ejector tube and the outer ring chamber, the upper air inlet burner increases the volume of the outer ring chamber in a limited space and realizes the tapered structure of the outer ring chamber, which is beneficial to the outer ring air flow. Uniform distribution, thereby improving the stability of flame combustion.

Description

technical field [0001] The invention relates to the field of household stoves, in particular to an upward air intake burner. Background technique [0002] At present, there are many kinds of upward air intake burners in China, which originate from different primary air intake structures. The Italian Sabaf burner with fully mature technology and the domestic Schindler burner are the most representative. The Schindler burner is a sheet metal structure, and the burner load is small, which cannot meet the needs of daily heavy-load stir-frying. [0003] At present, the upper air intake burner generally uses the inner ring fire cover and the outer ring fire cover to inhale air separately, but because the inner ring ejector and the outer ring chamber usually interfere with each other, the volume of the burner is too large or the outer ring chamber is blocked. The air is uneven. For example, the top-mounted burner of Chinese patent application CN207762894U, because the main fire i...

AI Technical Summary

Problems solved by technology

The Schindler burner is a sheet metal structure, and the burner load is small, which cannot meet the daily needs of large-load stir-frying.

[0003] At present, the upper air intake burner generally adopts the inner ring fire cover and the outer ring fire cover to intake air separately, but because the inner ring ejector and the outer ring chamber usually interfere with each other, the volume of the burner is too large or the outer ring chamber is blocked. Uneven air

For example, the top-mounted burner of Chinese patent application CN207762894U, because the main fire injection pipe 6 and the small fire injection pipe 4 all occupy the space of the combustion chamber 8, the gas distribution of the combustion chamber 8 is caused to be uneven, which will affect the outer ring fire cover The combustion stability of the flame
