Burner with outer outer peripheral soft fire, stove and control method

Abstract

The invention discloses a burner with outer peripheral soft fire, a stove and a control method. The burner includes a burner body and a plurality of injection pipes, wherein the burner body includes a central through hole; the outer side wall of the burner body is peripherally provided with a plurality of outer peripheral strong fire holes and a plurality of outer peripheral soft fire holes which are staggered or vertically arranged side by side; the outer peripheral strong fire holes communicate with the first injection pipe; and the outer peripheral soft fire holes communicate with the second injection pipe. The burner disclosed by the invention has outer peripheral fire, including outer peripheral strong fire and outer peripheral soft fire; it is guaranteed that the flame length of the outer peripheral soft fire holes is unchanged compared with that of the outer peripheral strong fire holes; injection and combustion are maintained in an optimal state all the time, so that the outer peripheral soft fire is distributed in a large range and has high thermal efficiency without being gathered at the bottom of a pot, thus the bottom of the pot is heated more evenly, and a good cooking experience is achieved.

Description

technical field [0001] The invention relates to the technical field of cookers, in particular to a burner with a small outer ring, a cooker and a control method. Background technique [0002] When gas stove manufacturers improve the thermal efficiency of gas stoves, because of the testing standards: household gas stoves only measure the thermal efficiency of the maximum firepower state, and the flame of each fire hole is in the longest state, and the combustion efficiency is the highest. But Chinese people have different needs for firepower when cooking. [0003] For household gas stoves on the market, in order to achieve more firepower divisions, when adjusting the firepower, a single fire hole is not only in the maximum firepower and extinguished state, but also has an intermediate fire state between the two. The firepower state of the middle small fire is achieved by reducing the supply of gas, but the flame combustion in the middle state is not in the best state, the ga...

AI Technical Summary

Problems solved by technology

The firepower state of the middle small fire is achieved by reducing the supply of gas, but the flame combustion in the middle state is not in the best state, the gas supply is small, the ejection becomes worse, and the flame of the small fire is short, and the relative distance from the bottom of the pot is longer. Far, the combustion efficiency is lower than that of the fire state

[0004] In addition, most atmospheric stoves on the market have two ring fires, and most of them have a fire cover for the outer ring fire and the inner ring fire, and the structure is complicated.

The firepower division of atmospheric burners is mostly large fire on the outside, low fire on the inside, and medium fire in the middle. The firepower of the small fire is too concentrated on the bottom of the pot. When cooking scenes such as pancakes, it is easy to burn the pan locally, and the cooking experience is not good enough.
