Low noise and powerful burner

Abstract

The invention discloses a burner with low noise and high firepower, comprising a cylindrical outer shell and a cylindrical inner shell, the inner shell is sleeved in the outer shell, the top of the outer shell and the top of the inner shell are closed and connected, and a sandwich is formed between the outer shell and the inner shell Cavity, the bottom of the outer shell is provided with an air inlet, the bottom of the inner shell is sealed, and the inner cavity of the inner shell is set into at least two or more steps that expand step by step from bottom to top. All have ventilation holes throughout. The air blown out of the bottom cavity is ejected from the space corresponding to the cavity of the corresponding layer, and the air blown out of each upper cavity can be ejected from the space corresponding to the expansion of the corresponding stage, so that the airflows of different heights are sprayed out. Compared with the traditional one, the collision and pushing of the air conditioner are greatly weakened, which can effectively reduce the turbulence phenomenon, and the offset of the jetting force between the different heights of the air flow to the outside of the burner will also be effectively weakened.

Description

technical field [0001] The invention relates to the technical field of burners. Background technique [0002] Gas stoves used in some professional kitchens such as the catering industry are often equipped with a blower in order to increase the firepower. The burner connected to the fan consists of a cylindrical outer shell and an inner shell, the inner shell is set inside the outer shell, and the top of the outer shell and the inner shell There is a closed connection between them, and a sandwich cavity is formed between the outer shell and the inner shell. The bottom of the outer shell is provided with an air inlet, the bottom of the inner shell is sealed, and the side wall of the inner shell is provided with vent holes all over. At present, the inner shell is used as a furnace cavity for combustion, and no matter what kind of burner it is, the inner shell is all set into a straight cylindrical shape. The way of mixing gas is divided into gas mixing inside the furnace cavit...

AI Technical Summary

Problems solved by technology

When burning, in the limited space of the straight cylindrical shape of the inner shell, the space that was originally filled by the airflow blown from the lower layer is blown into the upper airflow, and the collision between the airflows is more intense, and the airflows push and cancel each other. The strong flow will cause a lot of combustion noise, and the strong turbulent flow will offset the strength of the airflow ejected from the barrel mouth, resulting in insufficient flame height and insufficient firepower of the gas stove
