AI Technical Summary

Technical Problem

Existing gas stoves produce little flame variation when stir-frying, resulting in poor stir-frying effects, and the improper gas-air mixing ratio leads to incomplete combustion.

Method used

An additional gas outlet pipe is added to the gas stove, and a first ring flame hole is set in the center of the burner. The mixing ratio of gas and air is precisely controlled through a double ejector structure to form a flame suitable for stir-frying.

Benefits of technology

It significantly increases the flame size of the gas stove during stir-frying, resulting in more complete combustion, which is suitable for the heating needs of Chinese stir-frying, especially for the curved bottom of the wok.

Abstract

The application provides a gas stove, which comprises a burner assembly, a gas valve assembly and a switch assembly. The burner assembly comprises a burner body, a first fire cover and a second fire cover, wherein the burner body defines a first gas cavity, a second gas cavity and a third gas cavity which are independent of each other. The first fire cover comprises a first ring fire hole and a second ring fire hole, and the second fire cover comprises a third ring fire hole. The first ring fire hole, the second ring fire hole and the third ring fire hole are arranged from inside to outside. The gas valve assembly comprises a valve body, a first gas outlet pipeline, a second gas outlet pipeline and a third gas outlet pipeline. The first gas outlet pipeline is communicated with the first gas cavity. The switch assembly is arranged between the first gas outlet pipeline and the first gas cavity. When it is needed to perform explosive frying, the switch assembly is opened. At this time, the first gas outlet pipeline and the first gas cavity are communicated, so that the flame at the first ring fire hole is increased, the flame at the middle position is realized from nothing to something, and the explosive frying effect is improved.
