Gas burner capable of stably transferring fire

Abstract

The invention provides a gas burner capable of stably transferring fire. The burner comprises a gas mixing chamber, an burner ring with an annular burner ring body and a burner cap, wherein a secondary air supply channel communicating with a secondary air annular channel inside the gas mixing chamber is formed in the side wall of the gas mixing chamber, a main fire transmission groove radially extending is formed in the bottom of the burner ring body, the local upper wall of the secondary air supply channel corresponding to the main fire transmission groove penetrates upwards to form a throughgroove, and a main fire transmission groove cover is arranged at the top end of the through groove to form a fire transmission channel. According to the burner, a part of secondary air in the secondary air supply channel is supplemented into the fire transmission channel, so that the sufficient, efficient and stable combustion of flame in the fire transmission channel is promoted; meanwhile, theresidual secondary air is continued to be supplemented into the secondary air annular channel, so that stable combustion of inner ring fire is guaranteed; and at the moment of ignition of the fire transmission channel, the secondary air supply channel below the fire transmission channel can serve as a pressure diffusion cavity, so that the stability of the inner pressure in the fire transmission channel is ensured, and the stable and rapid fire transmission is realized.

Description

technical field [0001] The invention relates to the field of gas stoves, in particular to a gas burner with stable fire transmission. Background technique [0002] In order to smoothly transfer the fire from the inner ring to the outer ring, the gas burner is generally equipped with a fire transfer structure, and the fire transfer structure is generally arranged above the outer ring fire cover, such as: the patent number is ZL201621154541.0 (authorized announcement number The Chinese utility model patent of CN206112934U) discloses a kind of burner fire cap, and it comprises fire cap body, offers fire-inducing groove at the top of fire cap body. This will cause the upper surface of the fire cover to be uneven, and the overflow will easily block the fire transmission structure, resulting in the inability of the inner ring fire to be transmitted to the outer ring. [0003] Further, the Chinese invention patent with the application number 201410116688.X (publication number CN10...

AI Technical Summary

Problems solved by technology

In this patent, the structure of the fire transmission groove is a relatively closed channel, and the air in the fire transmission groove is insufficiently replenished, resulting in failure of fire transmission or affecting the speed of fire transmission, and when combustion occurs in the fire transmission groove, the fire transmission groove cannot be replenished to the inner ring Air, resulting in incomplete combustion of the burner and low thermal efficiency
