Description
Technical field
The present invention relates to a kind of high heat load high efficiency fuel gas stoves to have burner, belongs to gas cooker field.
Background technique
For current combustion device to be widely applied in family kitchen, the existing gas stove burner thermal efficiency is high, but heat is negative
Lotus is less than normal, quick-fried firepower big requirement when can not achieve culinary cuisine.The market brand kitchen range thermal efficiency 75% but thermic load only has
4.0kW, another brand kitchen range thermic load in market can achieve the 4.2kW thermal efficiency 70%, and market brand kitchen range are using upper
Burner is entered the wind, thermic load also only has the 4.2kW thermal efficiency 70%.
If directly increase thermic load, full combustion is unable to when these burners are using combustion gas, and then cause in flue gas
CO concentration it is higher, the main reason for causing the above problem is that the combustion adaptive domain of burner is relatively narrow, can not meet big load
The energy gathering cap Heat-collecting effect of burning condition, certain burners is poor, causes the heat loss of burner larger, so that stove panel surface
Temperature it is higher so that auxiliary air inlet is reduced, the auxiliary air that burner needs supplements insufficient.In order to improve kitchen range combustion
The thermal efficiency of burning, many burners improve primary air ratio in exploitation design at present, and the main fire hole of external ring fire cover goes out air-flow
Speed is higher, necessarily reduces the combustion boundary range of burner, is easy to produce when using natural gas from flame phenomenon.So often
When ring fire cover is used for the burner of this high thermal efficiency in advising, the fire hole flame holding difference and biography fire of interior ring fire cover are bad.With
Family using when often misfire and light a fire when be easy it is flame-out.
In view of this, disclosing a kind of external ring fire cover in the patent document application No. is 201820410572.0 and having
The gas burner of the external ring fire cover, the fire output hole in above-mentioned documents are obliquely installed, it is difficult to guarantee going out for fire output hole
Air velocity, and then it is difficult to ensure the abundant of combustion of natural gas；It is public in the patent document application No. is 201610676818.4
A kind of external ring fire cover of gas stove burner is opened, the fire output hole in above-mentioned documents is that have upper discharge fire hole and lower discharge
Fire hole is constituted, while being passed fiery slot and being set up directly on fire cover ontology, the fire output hole outlet of the external ring fire cover in above-mentioned documents
The case where flow velocity degree is higher, and flame stability is poor, and natural gas is easy to appear in combustion from flame；Application No. is
A kind of cumulative component of gas-cooker is disclosed in 201611247951.4 patent document, though cumulative component in above-mentioned documents
It is so the double-deck setting, but exists simultaneously following defect bilayer energy gathering cap and only have combustion product gases logical with auxiliary air mixed gas supply one
Road supplements channel without the auxiliary air of enough outer ring flame and interior ring flame, and auxiliary air supplement is less, and fuel gas buring is not
Sufficiently, and channel tilts down and forms angle with horizontal direction, and intake resistance is bigger, while auxiliary air is easy by first
It causes oxygen content to decline after layer energy gathering cap heating, is unfavorable for the supplement of auxiliary air.Energy gathering cap in documents lacks liquid
Access device is easy to extinguish the blaze, cause danger after the liquid in pot overflows.
Summary of the invention
It is an object of the invention to overcome the above deficiencies in the existing technologies, and provide it is a kind of reasonable in design,
Heat loss is reduced, CO concentration in flue gas can be reduced, and makes the clean-burning high heat load high efficiency fuel gas stove tool combustion of combustion gas
Burner.
