AI Technical Summary

Technical Problem

When burning, the existing fully-up air intake burners have problems such as uneven mixing of gas and primary air, low combustion heat efficiency, high burner height and poor aesthetics, inconvenient user cleaning and poor inducing effect.

Method used

An upward air inlet burner is designed, adopting a structure of multiple nozzles and multiple induction tubes. The length of the induction tube is increased through the buffer chamber, improves the mixing uniformity between primary air and gas, and cancels the bottom cup structure, and installs the injector directly through the nozzle seat to improve the air replenishment efficiency. At the same time, the second induction tube is placed in the second gas mixing chamber to reduce the overall height and avoid air leakage risks.

Benefits of technology

The uniform mixing of gas and primary air is achieved, the combustion heat efficiency is improved, the overall height of the burner is reduced, the aesthetics is improved, and the user's cleaning work is facilitated, while the injection effect and combustion sufficiency are improved.

Abstract

The present invention relates to an upper air inlet burner, characterized in that it includes a first ejector tube, a base surrounding the tube wall of the first ejector tube, a buffer cavity surrounding the tube wall of the first ejector tube and formed by the gap between the outer periphery of the tube wall of the first ejector tube and the base, and a first fire cover arranged at the central position of the base, and a first centrally located air mixing chamber is formed between the base and the first ejector tube. The air outlet end of the first ejector tube is fluidically connected with the first air mixing chamber through the buffer cavity, and the air inlet end of the first ejector tube is adapted to be equipped with a first injector. Compared with the prior art, the advantage of the present invention is that the first ejector tube is arranged in the base and has a buffer cavity, which effectively increases the length of the first ejector tube. At the same time, the setting of the buffer cavity enables the primary air / gas mixture ejected from the air outlet end of the first ejector tube to have a buffer space.
