Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in more detail.
Referring to figs. 1 through Fig. 4, a kind of burner, including burner 10, outer fire cover 20 and inner fire cover 30, burner 10 includes outer shroud hybrid chamber 11 and inner ring hybrid chamber 12;nullOuter fire cover 20 is positioned on outer shroud hybrid chamber 11,Inner fire cover 20 is positioned on outer shroud hybrid chamber 11,Burner 10 is provided with on the diapire of passage area 13 between outer shroud hybrid chamber 11 and inner ring hybrid chamber 12 passage 14,Atmosphere below passage 14 and burner 10,Cleaning ware 60 it is additionally provided with in passage area 13,Cleaning ware 60 has for inner ring hybrid chamber 12、The central through hole 61 that the thermocouple 40 of burner and ignition electrode 50 pass、The some fresh air inlets 62 being laid in central through hole 61 periphery and be arranged on outer edge one circle rib 63,At least partly the fresh air inlet 62 orthographic projection on the diapire of passage area 13 is positioned at passage 14,The most at least part of fresh air inlet 62 with passage 14 just to connecting,Avoid blocking the air inlet tonifying Qi of passage 14 owing to arranging cleaning ware 60.
In the present embodiment, outer fire cover 20 is located immediately on outer shroud hybrid chamber 11, inner fire cover 30 is located immediately on inner ring hybrid chamber 12, then eliminate the air distribution disk between burner and fire cover in prior art, owing to air distribution disk structure is complicated, cost is high, then greatly reduce the production cost of burner;Simultaneously, air vent 14 is had on passage area 13 diapire between outer shroud hybrid chamber 11 and inner ring hybrid chamber 12 on burner 10, air vent 14 and the lower section atmosphere of burner 10, and the cold air during air is gas-cooker drain pan below burner 10, this part cold air supplements air owing to the suction function of high-temperature flue gas can be extracted at burner flame, effectively increase the air capacity needed for the inner-ring fire burning of interior ring fire and outer ring fire, improve firepower;It addition, be provided with cleaning ware 60 on passage area 13 diapire, i.e. can guarantee that burner cleans design, will not hinder again the ventilation tonifying Qi effect of passage 14, does not interferes with the firepower improving burner.
Further, as it is shown on figure 3, passage 14 is in strip arc, on the diapire of passage area 13, circumferentially 3-5 is individual, and Fig. 3 show uniform 4;As shown in Figure 4, fresh air inlet 62 is at central through hole 61 peripheral laying one circumference of cleaning ware 60, and generally circular in shape, the triangle in hole or hexagon, the gross area of fresh air inlet is 550 ~ 650mm2In the range of, with efficient air intake, and the diameter of single fresh air inlet 62 is less, to avoid the cleaning action of impact cleaning ware 60.
, at the spilling food of cleaning ware 60 being provided with a circle dash boss 64 at the edge of central through hole 61, play backstop action in heart through hole 61 falls into inner ring hybrid chamber 12 from which for anti-falling stop, more improve burner cleans design degree.
Owing to the present embodiment burner eliminates air distribution disk, then the flame distribution uniformity of burner is had certain adverse effect, cause flame distribution uneven, for solving this problem, further, the present embodiment burner has three circle fire distributions, in addition to the one of inner fire cover 30 irises out fire, outer fire cover 20 includes external annulus 21, roof and internal ring wall 22, a circle flame envelope fire output hole 211 it is laid with on external annulus 21, a circle internal flame fire output hole 221 it is laid with on internal ring wall 22, internal flame fire output hole 221 has 10 ~ 14 groups, often group fire hole quantity is 2 ~ 4, fire hole is stepped hole, a diameter of Φ 1.5 ~ Φ 1.8 in hole;Accordingly, on the external annulus of outer shroud hybrid chamber 11, correspondence is laid with auxiliary air hole 111, on the internal ring wall of outer shroud hybrid chamber 11, also correspondence is laid with auxiliary air hole 112, the flame of flame envelope fire output hole 211 is provided secondary air supply to form the outer ring fire of outer fire cover 20 by auxiliary air hole 111, the flame of internal flame fire output hole 221 is provided secondary air supply to form the inner-ring fire of outer fire cover 20 by auxiliary air hole 112, thus realize without firepower dead angle, inside and outside flame distribution is uniform, is suitable for the culinary arts such as quick-fried, pancake and fried egg.
Outer ring fire and interior ring fire in order to solve outer fire cover 20 are interfered and yellow flame are occurred, make the difficult problem that CO content in smoke is high, as shown in Figure 5, the present embodiment is laid with on the roof of outer fire cover 20 boss 23 the most continuously, each boss 23 has the triangle madial wall 231 of inclination, the triangle lateral wall 232 tilted, the triangle left side wall 233 tilted and the triangle right side wall 234 tilted, the pyramid shape that four triangular side walls tilted make boss 23 present point, this boss 23 is between outer ring flame and inner ring flame, effectively prevent the interference of outer ring flame and inner ring flame, solve yellow flame phenomenon that dicyclo flame occurs because interfering with each other and CO content in smoke such as exceeds standard at the phenomenon.Additionally, the boss 23 of pyramid shape is laid continuously, i.e. in the middle of continuously every, the sidewall of the groove 24 formed in the middle of the most adjacent two boss right side wall of left side wall and the adjacent lands of a boss (namely wherein) is then for inclined plane, the groove 24 of sloped sidewall can be when using gas-cooker to occur that soup is flowed into fire cover due to excessive pot, effectively play the effect of water conservancy diversion, solve the common fire cover soup without flow-guiding structure and bleed around thus occur that blocking is burnt the phenomenon of fire hole.
Further, the angle of inclination of four triangular side walls 231,232,233,234 tilted is 5-10 °.
With reference to Fig. 6 and Fig. 7, internal flame fire output hole 221 is inner small and outside big shoulder hole, by arranging the internal flame fire output hole 221 of the most stepped (the most step-like), then air is after 20 points of air cavitys of outer fire cover flow out, when flowing through internal flame fire output hole 221, the speed that inner small and outside big internal flame fire output hole 221 can make air flow is gradually lowered from inside to outside, prevents crossing ambassador's inner-ring fire because of air velocity and outwards waves and the interference of outer ring fire, the most effectively prevents the interference of outer ring flame and inner ring flame.
The present embodiment also proposed a kind of gas-cooker, and with reference to Fig. 8, including burner etc., the concrete structure of burner can be found in embodiment and the description of accompanying drawing 1 to Fig. 7 of burner of the present invention, does not repeats them here.
The above, be only presently preferred embodiments of the present invention, is not the restriction that the present invention makees other form, and any those skilled in the art are changed possibly also with the technology contents of the disclosure above or are modified as the Equivalent embodiments of equivalent variations.But every without departing from technical solution of the present invention content, any simple modification, equivalent variations and remodeling above example made according to the technical spirit of the present invention, still fall within the protection domain of technical solution of the present invention.
