Description
Technical field
The utility model is related to a kind of gas kitchen ranges, especially a kind of burner fire lid of gas kitchen ranges.
Background technology
Gas-cooker is the kitchen tools commonly used in people's daily life, and gas-cooker is broadly divided into LFG for fuel is fired
The kitchen range of burning, LFG can be natural gas, liquefied gas, biogas etc., and the species according to LFG is different, gas-cooker
Various, such as liquefied gas cooker, gas range, natural gas range can be divided into.Certainly, gas-cooker can also be divided into list according to structure difference
Stove, double stoves, single-hole range, multi-hole kitchen range, desk-top embedded stove etc..
Burner is the important component of gas-cooker, and the burner structure of current household gas range is generally circular configuration, burning
In polycyclic flame forms.A kind of burner as disclosed in the Chinese patent of Application No. 201410719979.8, including furnace head base；
Distributor, is connected with furnace head base；Central flame cap, is arranged in distributor and is connected with distributor；External ring fire cover, its inner circumferential
Face has fire-assembling hole in multiple, and its outer peripheral face has multiple outer fire jetting holes, and external ring fire cover is located at the periphery of central flame cap and sets
It is connected in distributor and with distributor, wherein, external ring fire cover cooperates with distributor so that external ring fire cover has cohesion
First state and disconnect the second state for connecting that fire hole is connected with outer fire jetting hole；And for example Application No. 201610200024.0
Chinese patent disclosed in a kind of burner of the steady flame structure of band, including small fire cover and annular fire cover, distribution of air flow body, small fire
Lid is located at centre position in fire cover, has main fire hole in fire cover, and positioned at the lower section of main fire hole, the steady flame with inside and outside extension leads to
Road, wherein fire cover form a cavity with distribution of air flow body, are communicated with main fire hole and the steady flame passage, and small fire cover is divided with air-flow
The gas channel of part is communicated, and also there are some stomatas in small fire outer side of lid portion, for producing combustion flame.
These above-mentioned existing burners, its flue gas for producing is generally laminar condition, has with the intensity that exchanges in the bottom of a pan
Limit, the thermal efficiency is relatively low.
Utility model content
Technical problem to be solved in the utility model is directed to the problem that above-mentioned prior art is present, there is provided a kind of thermal effect
The burner fire lid of rate.
The utility model solve the technical scheme that is used of above-mentioned technical problem for：A kind of burner fire lid, including ring-type
External ring fire cover, multiple outer shroud fire holes are offered on the perisporium of the external ring fire cover, it is characterised in that：The top of the external ring fire cover
Face is provided with the flange that at least two-layer raises up, the flange diametrically inside and outside compartment of terrain arrangement, adjacent two layers flange it
Between formed to recessed depressed part, and the flange be higher than outer shroud fire hole.
To avoid because the spacing between adjacent two layers flange is too small again, it is impossible to form restriction effect, avoid because of adjacent two layers
Spacing between flange is excessive and cause velocity of flue gas excessively slow, the spacing between adjacent two layers flange be 5mm~10mm.
It is described to avoid because depth is too small cannot again avoiding depth excessive and be unfavorable for cleaning so that flue gas spreads
The depth of depressed part is 4mm~5mm.
For the flame for avoiding outer shroud fire hole when in use is heated to pan bracket, and thermal loss is caused, and be easy to cleaning, institute
The top surface for stating external ring fire cover is further opened with multiple breach, and the bottom of the breach is not higher than outer shroud fire hole, so that described outer
Ring fire cover does not have outer shroud fire hole in indentation, there.
To expand the size adjustment scope of flame, the burner fire lid also includes the interior ring fire on the inside of external ring fire cover
Lid.
For ease of the high-temperature flue gas circulation that the flame of interior ring fire cover is formed, the interior ring fire cover is less than external ring fire cover.
Compared with prior art, the utility model has the advantage of：By setting multilayer flange, may be such that high-temperature flue gas exist
By when, form continuous throttling expansionary effect, increase the heat exchange coefficient with pan, thus improve the thermal efficiency.

The use state schematic diagram of the burner that Fig. 3 is applied by fire cover of the present utility model；
Fig. 4 is the sectional view of Fig. 3.
Specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
Referring to Fig. 1 and Fig. 2, a kind of burner fire lid, including interior ring fire cover 1 and external ring fire cover 2, interior ring fire cover 1 are in cylinder
Shape, in annular shape, interior ring fire cover 1 is located at the inner side of external ring fire cover 2 to external ring fire cover 2, and less than external ring fire cover 2.
Inner ring fire hole 11 is offered on the top of interior ring fire cover 1 and perisporium, outer shroud is offered on the perisporium of external ring fire cover 2
Fire hole 24.
The top surface of external ring fire cover 2 is provided with the flange that at least two-layer raises up, in the present embodiment, with two-layer,
That is as a example by the first flange 21 and the second flange 22.The compartment of terrain of first flange 21 is arranged in the radially inner side of the second flange 22, first
There is depressed part 23 between the flange 22 of flange 21 and second.First flange 21 and the second flange 22 are higher than outer shroud fire hole 24, height
Difference is 4mm~8mm, more preferably 6mm.
The top surface of external ring fire cover 2 is further opened with breach 25, and breach 25 is advisable with 4~8, and width is preferably 12mm.Lack
The bottom of mouth 25 is not higher than outer shroud fire hole 24, and thus external ring fire cover 2 does not have outer shroud fire hole 24 at breach 25.
Referring to Fig. 3 and Fig. 4, when using, the breach 25 on external ring fire cover 2 is corresponding with the support frame 31 of pan bracket 3, pan 4
It is supported on the support frame 31 of pan bracket 3.Thus, the support frame 31 of pan bracket 3 avoids flame heating not just to outer ring fire hole 24
Support frame 31 and cause heat-energy losses.And because interior ring fire cover 1 is less than external ring fire cover 2, the height of the flame formation of interior ring fire cover 1
A warm flue gas part can be flowed out from breach 25, and another part can be flowed out by the gap between fire cover and the base plate of pan 4.Additionally,
When thering is liquid to overflow in pan 4, flow to by the liquid in breach 25 is convenient to ground and remove.
When high-temperature flue gas flow through between external ring fire cover 2 and the bottom of pan 4, at flange, external ring fire cover 2 and pan 4
Spacing between bottom reduces so that flue gas is compressed, and the spacing between recess, external ring fire cover 2 and the bottom of pan 4 increases
Greatly so that flue gas is expanded, thus, by setting multilayer flange, may be such that high-temperature flue gas by when, form continuous throttling expansion
Effect, increases heat exchange coefficient, improves the thermal efficiency.
The spacing that second flange 22 is not less than between the first flange 21, and the first flange 21 and the second flange 22 is 5mm
~10mm, thus can avoid because the spacing between adjacent two layers flange is too small, it is impossible to form restriction effect, be avoided that again because adjacent
Spacing between two-layer flange is excessive and causes velocity of flue gas excessively slow.The depth of depressed part 23 is 4mm~5mm, thus can be avoided
Cannot cause that flue gas spreads because depth is too small, be avoided that depth is excessive again and be unfavorable for cleaning.
