Burner and gas stove having same

Abstract

The invention discloses a burner and a gas stove having the same. The burner comprises at least two loops of and orderly winding burner bodies, wherein the burner body winded by each loop consists of a mixing cavity and a cover plate covering the mixing cavity; the burner at least comprises a loop atmosphere burner and a loop full-premix burner; primary air coefficient of the full-premix burner is no less than 1; and the cover plate of the burner body in the innermost side is embedded into the cover plate of the burner body on the secondary innermost burner body. The burner possesses high heat efficiency and small size.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a burner and a gas stove with the same. Background technique [0002] In the existing three-ring fire burner, the inner ring fire and the middle ring fire are independently distributed, and the combustion methods are all atmospheric combustion. According to the combustion principle of the atmospheric burner, gas and primary air are pre-mixed in the injection part of the burner, and the mixture of gas and air cannot satisfy complete combustion. Therefore, when arranging the combustion fire hole, it is necessary to provide sufficient secondary air passage area, especially A large secondary air channel should be left in the center of the head, otherwise the CO content in the flue gas will exceed the standard. Therefore, the temperature of the bottom of the pot at the secondary air passage of the outer ring fire and the inner ring fire of the atmospheric burner is relatively low....

AI Technical Summary

Problems solved by technology

[0003] At the same time, the three-ring fire burner with the inner ring fire and the middle ring fire independently arranged needs to be equipped with sufficient secondary air channels, so the diameter of the burner must be enlarged. The diameter of the usual three-ring fire burner is Φ150mm-Φ160mm, and the diameter of the burner is If the temperature is increased, the time for the high-temperature flue gas to flow along the bottom of the pot to contact the bottom of the pot will inevitably decrease, which is not conducive to the improvement of thermal efficiency.
