Description
Technical field
A kind of burner is the utility model is related to, is mainly used on gas kitchen ranges.
Background technology
Traditional household gas utensils carry interior ring fire (small fire) and outer ring fire (big fire), in order to ensure kitchen range are normal
Small fire and the function of big fire, in the design of household cooking utensil burner, the geometry site of interior ring fire cover and external ring fire cover is non-
Often important, this can directly influence the discharge of flue gas, because the position limitation and atmospheric burner of interior ring fire cover are partly-premixed
The characteristics of (primary air ratio is less than 1), interior ring fire is additionally required the supply of extraneous auxiliary air, and conventional mode is to increase at present
Add mixing chamber part, in mixing chamber lateral opening hole, set secondary-air passage to give inner ring auxiliary air.Related patent document can
Disclosed with application reference number for CN200810163232.3 Chinese invention patent application《The air intake of multi-cavity integral combustor is adjusted
Regulating device》(application publication number CN101440962A)；Can with application reference number be 201410079858.1 Chinese invention

However, the introducing of mixing chamber parts can increase cost, while mixing chamber is difficult to clear up after long-term use, to user
Experience bad；A kind of conventional solution is that outer shroud is designed to that auxiliary air opens, i.e., outer shroud is designed into separated several pieces,
Passage between every piece is to open time air openings passage, and this can make the Means of Secondary Air Supplement in the external world to inner ring, but also have one
Problem, it is exactly that will certainly influence arrangement of the outer shroud fire hole on outer ring, i.e. outer shroud fire hole after outer shroud opens several auxiliary air openings
Quantity can reduce, this can influence the fire hole heating intensity of outer shroud fire hole, while also be unfavorable for the uniformity of outer shroud flame；Together
When, the thermal efficiency is one important performance indications of kitchen range, and it is to improve the main path of the thermal efficiency, wherein pan bracket to reduce heat loss
The ratio that accounts for of heat loss it is higher, the exposed raising that pan bracket can be caused outwards to radiate, be unfavorable for the kitchen range thermal efficiency of pan bracket；Separately
Outside, when Means of Secondary Air Supplement, not merely auxiliary air amount is sufficient, while azimuth tendency is also critically important during Means of Secondary Air Supplement,
Move towards supply along flame and can at utmost reduce the resistance of supply, make supply more it is rapid more in place.
Therefore, it is highly desirable to design a burner, the burner is taken into account under conditions of outer shroud auxiliary air opening
The quantity of outer shroud fire hole, the disadvantage for the difficult cleaning that mixing chamber is brought is removed, while and can reduces the thermal efficiency of pan bracket,
And can is optimized in terms of biography easy to clean.
