Abstract

The invention relates to a combustor used for a gas stove. The combustor comprises a big fire cover, a small fire cover and a base, and is characterized in that fire outlet holes, air supply passageways and gas mixing cavities are formed in the big fire cover, fire outlet holes are formed in the small fire cover, a base inner ring and a base outer ring are arranged on the base, and gas mixing cavities and air supply passageways are formed in the base outer ring. The air supply passageways of the big fire cover are matched with the air supply passageways in the base outer ring to form integral air supply passageways. The gas mixing cavities in the big fire cover are matched with the gas mixing cavities of the base to form integral gas mixing cavities. According to the combustor, mixed gas is mixed in the mixing cavities and combusted in the fire outlet holes of the fire covers, sufficient air supply is conducted through the air supply passageways, and therefore the mixed gas can be sufficiently combusted, and the technical effects of improving the heat flux and the heat efficiency of the combustor are achieved.

Description

A kind of burner for gas kitchen range

Technical field

Patent of the present invention relates to a kind of burner, and this burner application, on household gas utensils and integrated kitchen range, belongs to kitchen utensils technical field

Background technology

From national policy and citizen requirement, low-carbon emission and low energy consumption, become a kind of trend of important in a domestic gas tool problem and technical development in the future.Existing gas stove burner, its combustion gas mixing cavity mostly is 1, indivedual producers accomplish 3～5, but the distribution of the fire output hole in fire cover is generally circumferentially, indivedual producers radially distribute, but because air can not supplement the gas to burning in time, so the thermal efficiency of the burner that current kitchen range are used accomplishes that 60% has arrived the limit (GB16410-2007).

Summary of the invention

Technical problem to be solved by this invention is air supply and the multiple combustion gas mixing chamber alone that a kind of 360 degree total spaces are provided for the above-mentioned state of the art, makes air mixture a kind of brand-new full air intake burner of air supply more fully when mixing and burning more fully.Thereby not only improve the thermal efficiency, and improved thermic load, reached low emission that country advocates and the requirement of low energy consumption, solved again the eating habit of Chinese Consumer's quick-fried simultaneously.

The present invention solves the problems of the technologies described above adopted technical scheme: a kind of full air intake burner, comprise large fire cover, little fire cover and base, aforesaid large fire cover fire output hole can radially distribute or arc covers face to being distributed in big fire, and having the radially distribution corresponding with large fire cover fire output hole or arc to the multiple independently air supply passages that distribute, it is through fire cover fire output hole root.Aforesaid big fire be stamped can radially distribute or arc to distribute multiple independent combustion gas mixing chamber.Previous combustion chamber have with large fire cover corresponding radially distribute or arc to the passage of the multiple independently air supplies that distribute, it is with large fire cover, and little fire cover is assembled together by machinery, closely cooperates, form an integral burner, mist is mixed and air supply fully.Thereby improve the thermal efficiency and the heat flow of burner in the time of burning.

As preferentially, air supply passage be base and big fire cover rim radially or arc to distribution, and corresponding with large fire cover fire output hole, form multiple air supply passages.

As preferentially, combustion gas independence hybrid chamber be base and big fire cover rim radially or arc to distribution, and with large fire cover fire output hole, air supply passage is corresponding, forms multiple independently combustion gas mixing chamber.

Described air supply passage is that base and big fire mount cover and join entirety of rear formation, extends through fire cover top from bottom, combustion chamber.

Described independent combustion gas mixing chamber is that base and big fire mount cover an entirety of joining rear formation, and combustion gas is mixed more fully.

Compared with prior art, the invention has the advantages that: by multiple air supply passages, solve the problem of mist acomia timely supply of air in the time of burning; By multiple independently combustion gas mixing chamber, solve mist and mix inhomogeneous problem, thereby improve the sufficient combustion of mist, reach and improve the thermal efficiency and thermic load, solve the technical bottleneck of current combustion device;
