Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in Figures 1 to 8, preferred embodiment of the present utility model, a kind of burner of gas-cooker, it includes burner 1, Central airway road 2 and outer shroud guide pipeline 3 are installed on the burner 1, the top from-inner-to-outer of the burner 1 is set successively There is center to mix air cavity 4, annular air chamber 5 and outer shroud and mix air cavity 6, the center is mixed air cavity 4 and connected with the central airway road 2 Logical, the outer shroud mixes air cavity 6 and connected with the outer shroud guide pipeline 3, and the outside of the burner 1 is provided with and the annular air chamber The air admission hole 7 of 5 connections, the center are mixed and central flame cap 8 are covered with air cavity 4, and the outer shroud mixes and is covered with outer ring fire on air cavity 6 Lid 9, the central flame cap 8 include central flame cap body 81 and the direct-injection square 82 located at the top of central flame cap body 81, The direct-injection square 82 is in the laminated structure for being covered with mesh, and the periphery wall top of the central flame cap body 81, which is uniformly distributed along the circumference, to be set There is a side fire hole 83, the center bore inner wall of the external ring fire cover 9 is the inclined plane 91 that internal diameter becomes larger from the bottom up, the outer shroud The end face of fire cover 9 is uniformly distributed with the straight fire hole 92 for spraying combustion gas and being connected with the mixed air cavity 6 of the outer shroud that can be inclined upwardly, institute along the circumference Combustion gas can be sprayed to burner centre inclined upward and mix what air cavity 6 connected with the outer shroud by stating inclined plane 91 and being uniformly distributed with along the circumference Inward turning fire hole 93, the inward turning fire hole 93 and the straight fire hole 92 are strip hole, the inward turning fire hole 93 and the straight fire hole 92 are connected.
During burner operation, a part of combustion gas enters center by central airway road 2 and mixes air cavity 4, and air cavity 4 is mixed with center Being sprayed vertically through central flame cap 8 after interior air mixing, another part combustion gas enters outer shroud by outer shroud guide pipeline 3 and mixes air cavity 6, And sprayed after being mixed with the air that outer shroud is mixed in air cavity 6 through the eddy flow of external ring fire cover 9.So, the utility model passes through in direct injection The combination of internal heat lid 8 and vortex external ring fire cover 9, the design of traditional three ring fires burning is abandoned, has utilized direct injection center Fire cover 8, make the hard straight upward direct-injection of flame, burning is concentrated, and the thermal loss that auxiliary air is taken away is few, so as to improve burner The thermal efficiency, using vortex external ring fire cover 9, flame is covered larger combustion zone from outer to inner, flame distribution is uniform, from And the design that ring fire is burnt in tradition can be cancelled, the auxiliary air of burner internal needs is reduced, namely annular air chamber 5 Smaller volume can be designed, and then the diameter of burner can be with relatively small.In addition, the side fire hole 83 on central flame cap 8 can Flame is extended to the top of annular air chamber 5, effectively reduce between central flame cap 8 and external ring fire cover 9 without fiery region area, make Flame on burner is more uniform, when effectively avoiding using the flame in the bottom of a pan it is uneven and caused by the problem of being locally burned.
More preferably, in the present embodiment, in order to which swirl injection effect, the inward turning fire hole 93 and straight fire hole 92 is better achieved Projection and the end face radius of the external ring fire cover 9 on the end face plane of the external ring fire cover 9 form first angle a (such as Fig. 6 It is shown), the first angle a is 0 degree~45 degree, preferably 25 degree, such to design the work for increasing single gas injection hole With area, make gas injection hole arrangement even closer;The center line of the depth direction of the inward turning fire hole 93 and straight fire hole 92 with The end face plane of the external ring fire cover 9 forms the second angle b (as shown in Figure 7), and the second angle b is 30 degree~90 degree, excellent Elect 45 degree as, such design makes combustion gas tilt ejection, and flame can preferably cover the interval region between gas injection hole, Flame footprint area is bigger, distribution is more uniform.
More preferably, in the present embodiment, the external ring fire cover 9 and the outer shroud, which mix, is provided with spacer ring 10 between air cavity 6, it is described every Ring 10 is erected at the outside that the outer shroud mixes air cavity 6, and the outer rim of the frame of external ring fire cover 9 is erected on the spacer ring 10.Thus, External ring fire cover 9 and outer shroud can be mixed air cavity 6 and surround the space to be formed increase by spacer ring 10, increased air content in mixed gas, ensured combustion Gas can fully burn.
More preferably, there is the flange part 11 upwardly extended, the flange in the present embodiment, on the upside of the outer rim of the spacer ring 10 Portion forms the interior step 12 of ring-type with the spacer ring 10, and the outer rim of the external ring fire cover 9 is erected on the interior step 12, so as to External ring fire cover 9 is facilitated to position and fix.
More preferably, there is the shirt rim portion 13 extended downwardly, the shirt rim in the present embodiment, on the downside of the outer rim of the spacer ring 10 Portion 13 is covered in front of the outside of the air admission hole 7, so as to prevent larger distinguished and admirable be directly blown into from air admission hole 7 from confusing flame, Ensure that fuel gas buring is stable.
More preferably, in the present embodiment, the outer shroud mixes air cavity 6 and is provided with least two and is evenly spaced apart to be located at the annular The outside of air chamber 5, the air admission hole 7 is the septal pathways between the mixed air cavity 6 of two adjacent outer shrouds, thus rationally sharp With the space of burner, make the structure of burner compacter.
More preferably, in the present embodiment, the mesh aperture of the direct-injection square 82 is 1.0mm~1.2mm, and pitch of holes is 1.2mm~2.4mm, from there through the aperture and spacing for rationally designing mesh, make outlet more uniform, effectively anti-anti-avulsion fire, from Phenomena such as flame.
More preferably, in the present embodiment, the internal perisporium of the upper end oral area of the central flame cap body 81 is provided with the interior platform of ring-type Rank, the side wall of the interior step upwardly extend portion by the way that the direct-injection square 82 is pressed on the interior step to in-flanges. Such design, direct-injection square 82 can be fixedly secured, effectively prevent direct-injection square 82 from falling from central flame cap body 81 Fall.
Above disclosed is only preferred embodiment of the present utility model, certainly can not be new to limit this practicality with this The interest field of type, therefore the equivalent variations made according to present utility model application the scope of the claims, still belong to the utility model and covered Scope.
