Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail:
With reference to accompanying drawing 1, shown in Fig. 2 and Fig. 3, a kind of three ring fire burner for gas stove of the present utility model, comprise big fire cover 1, little fire cover 2, burner body 3 and the venturi be connected with this burner body (comprise outer ring channel venturi 6, outer-loop passage venturi 7 and inner ring channel venturi 8), burner body 3 comprises at least one outer ring channel, a middle ring passage and an inner ring channel, big fire cover 1 is provided with middle ring passage and outer ring channel, ring channel connection in ring passage and body in big fire cover, big fire cover outer ring channel is communicated with body outer ring channel, little fire cover 2 is provided with inner ring channel and is communicated with body inner ring channel, big fire cover 1 and little fire cover 2 respective channel all have fire output hole, big fire cover outer ring channel fire output hole 1A area is less than middle ring passage fire output hole 1B area, big fire cover outer ring channel fire output hole 1A is obliquely installed from bottom to top laterally, and in big fire cover, ring passage fire output hole 1B is obliquely installed from bottom to top to the inside, big fire cover outer ring channel fire output hole 1A exit position is higher than middle ring passage fire output hole 1B exit position." be less than ", " higher than " all have specific meanings, namely ensure can realize within the scope of existing burner for gas stove overall dimensions. hereinCan find out in FIG, pot body 5 is placed on pan bracket 4, and three ring flames are concentrated equably to the bottom of a pan heating, and efficient heat scatters and disappears.
Little fire cover 2 inner ring channel fire output hole 2A cross section is rounded, is obliquely installed laterally from bottom to top, pore diameter range 1.5 ~ 2.5mm.Big fire cover 1 outer ring channel fire output hole 1A cross section is rounded, pore diameter range 1.5 ~ 2.5mm, and in big fire cover, ring ring passage fire output hole 1B is rectangle, areal extent 1.5mm × 5mm ~ 1.5mm × 10mm.
Big fire cover 1 outer ring channel fire output hole 1A and vertical direction are that 30 ~ 60 ° of angles are arranged; In big fire cover, ring passage fire output hole 1A and vertical direction are that 30 ~ 60 ° of angles are arranged; Little fire cover inner ring channel fire output hole 2A and vertical direction are that 30 ~ 60 ° of angles are arranged.Comparatively middle ring passage fire output hole exit position, big fire cover 1 outer ring channel fire output hole 1A exit position exceeds 9 ~ 25mm.Big fire cover 1 external diametrical extent 120 ~ 140mm.Big fire cover lateral wall extends outward a ring-shaped platform and forms pressure flame cap 1C, and big fire cover outer ring channel fire output hole exit position is positioned at the below of pressure flame cap inner ring lower edge.
With reference to Fig. 1, big fire cover lateral wall comprise one have retracted downward tapering conical section and by the cylindrical section of conical section lower edge to downward-extension, cylindrical section has secondary air inlet 1D.The outer ring channel fire output hole of big fire cover comprises main fire hole 1A1 and stable flame hole 1A2, the arrangement of main fire hole circumference equi-spaced apart, the arrangement of stable flame hole circumference equi-spaced apart, and main fire hole and stable flame hole one by one interval misplace and arrange, and main fire hole aperture is greater than stable flame hole.
In the present embodiment, the while of three ring fires in combustion process, outer ring fire due to from the bottom of a pan than other two rings partially close to, even if Smaller load burns, the hot-fluid that flame produces pushes middle ring fire to, make whole fire cover one enclose outer ring fire and encase the main fire of middle ring, make its flame concentrate on center, the bottom of a pan, promote capacity usage ratio.The little burner of outer ring fire diameter 75mm on the market, although flame diameter is little, flame outer ring is without encasing heat effect, and the many thes bottom of a pan of not arriving of heat have been diffused into outside pot footpath.Although ring fire diameter has 80mm in this embodiment, produce flame heat regulating and will exceed much than the little fire cover efficiency of diameter 75mm outer shroud flame on the market owing to being encased effect by outer ring fire.While the main fiery B of middle ring is encased by outer ring fire, ring fire diameter in extruding, makes interior ring fire more can efficiency utilization.Further, burner body can make corresponding angle of inclination according to fire cover angle of inclination, strengthens the ejector capacity of auxiliary air, makes the main fire of middle ring and interior ring fire Thorough combustion release heat, reduces CO discharge capacity simultaneously.Further, because outer ring fire diameter is large, from flame, de-fiery phenomenon reliable steady flame during in order to effectively avoid cold conditions, the present embodiment burner big fire cover outer shroud fire hole top is provided with whole circle and presses flame cap, fire hole root both sides are provided with small fire hole and hold big fire, make its smooth combustion.
Although the utility model has illustrated by reference to preferred embodiment and has described, but those of ordinary skill in the art should understand, the description of above-described embodiment can be not limited to, in the scope of claims, the various changes in form and details can be made.
