Description
Technical field
This utility model is related to burner arts, more particularly, to a kind of external ring fire cover of gas stove burner.
Background technology
The external ring fire cover of existing gas stove burner is typically distributed with whole circle fire hole or whole circle fire groove, and gas-cooker uses
When, the pot pawl of pan bracket is difficult to the flame calcination avoiding not produced by external ring fire cover, so not only can produce the yellow flame of contact, and
During calcination, partial heat is conducted on kitchen range body, thus causing the loss of heat, such as：Application No.
The Chinese invention patent of (201610158663.5 application publication number is CN105627383A)《A kind of gas kitchen ranges》, Patent No.
The Chinese utility model patent of ZL201320120789.5 (Authorization Notice No. is CN203215741U)《A kind of pan bracket is embedded
Household gas range》Etc. the gas kitchen ranges structure disclosed in patent.
For this reason, there being technical staff to avoid the pot pawl quilt on pan bracket by the method increasing pan bracket circle body internal diameter at present
Fiery calcination, but this can cause another question again：The circle body of pan bracket excessive so that this pan bracket not to be suitable for diameter less
Pot, such as milk pot, less pan of diameter etc., easily cause pot landing when using reluctantly and unexpectedly occur.Although it is logical
Crossing to set up assists the mode of pan bracket can solve this problem to a certain extent, but so not only makes the complicated integral structure of kitchen range
Change, increase production process and cost, and fundamentally do not solve the above problems.As fully visible, existing external ring fire cover knot
Structure could be improved so as to the generation of pan bracket calcination problem can more effectively be avoided.
Utility model content
First technical problem to be solved in the utility model is to provide one kind can be prevented effectively from for prior art
Pan bracket is by the external ring fire cover of the gas stove burner of calcination.
Second technical problem to be solved in the utility model is to provide one kind can be prevented effectively from for prior art
Pan bracket by calcination, and can make burner continual and steady, efficiently and homogenous combustion burner external ring fire cover.
This utility model solves the technical scheme that adopted of above-mentioned technical problem：A kind of outer shroud of gas stove burner

The fire output hole connecting with described mixing chamber it is characterised in that circumferentially arranged on described fire cover body have at least three burn-out-proof areas,
And between adjacent burn-out-proof area, forming flame zone, described fire output hole is positioned only in described flame zone and is located at the outside of flame zone
Along upper.
Preferably, the top surface concave downward in each described burn-out-proof area and form burn-out-proof groove, the design of burn-out-proof groove is not only
Make the burn-out-proof effect to pan bracket pot pawl more preferably, and the passage that auxiliary air fills into can be constituted, so as to be preferably positioned at
Interior ring fire cover within external ring fire cover, flash hole and the fiery groove of biography supplement auxiliary air it is ensured that passing fiery groove, flash hole and internal ring
The oxygen of fire cover is sufficient, thus efficient burning.
Further, described burn-out-proof area is centrosymmetric centered on the center of circle of fire cover body, and described burn-out-proof groove is radially
Setting.
Further, the depth in each described burn-out-proof area is 0.1～10mm, thus air flow property in ensureing mixing chamber
On the basis of, preferably play burn-out-proof and build the function that auxiliary air fills into passage.
Preferably, being provided with the biography fire groove radially extending in each described flame zone, thus avoiding pan bracket to be burnt
It is ensured that smooth pass fire on the basis of burning.
For making biography fire more smooth, preferably, being provided with an above-mentioned biography fire groove in each described flame zone, and each biography
Fiery groove is centrosymmetric centered on the center of circle of fire cover body and arranges and be respectively adjacent to corresponding burn-out-proof area.
Preferably, the described thickness passing the fire cover body wall at fiery groove and flash hole place is more than other of fire cover body
Part, not only so that the fiery groove of biography and flash hole structure are more firm, and the flame stabilization that can guarantee that flash hole and pass fiery groove.
For making burning more stable, efficiently and uniform, preferably, described fire output hole at least includes being crisscross arranged up and down
Upper discharge fire hole and lower discharge fire hole, and lower discharge fire hole diameter be less than upper discharge fire hole diameter.
Preferably, a diameter of 1mm～2.8mm of each described fire output hole, and the duct central shaft of each fire output hole and level
The angle in face is 25 °～50 °, so that fire output hole forms the flame that a circle tilts upward on the edge of the outside of fire cover body.
Compared with prior art, the utility model has the advantage of：At least three burn-out-proof are circumferentially provided with fire cover body
Area, and between adjacent burn-out-proof area, form flame zone, and fire output hole is only distributed on the outside of flame zone along upper so that fire output hole produces
Flame can avoid pan bracket, be prevented effectively from pan bracket by calcination, reduce conduction of heat, reduce thermal loss.
