Abstract
The utility model discloses a burner cap. A fire hole 1 is arranged on the side wall of the cap. The cap is further provided with at least a secondary air supplementary hole 2 close to the fire hole so that secondary air required for combustion is greatly supplemented at the root of a flame 5 close to the fire hole to accelerate combustion adequately, to improve the combustion efficiency and to reduce the exhaust emission. In addition, the secondary air supplementary hole is easy to process on the cap and the cap is compact as a whole and is not complicated due to arrangement of the the secondary air supplementary hole.
Description
Technical field
The utility model relates to burner, specifically is a kind of burner fire lid, is mainly used on the embedded gas kitchen ranges of family expenses.
Background technology
Gas-cooker is common kitchen utensils, and how fully to effectively utilize combustion gas is the problem that people are concerned about always.For improving the efficiency of combustion of combustion gas, people have developed the gas-cooker of many different structures, and wherein major part is that the burner structure that is directed against gas-cooker improves.Like the patent No. is the burner that the Chinese utility model patent of ZL03237812.2 discloses a kind of gas-cooker, and ring fire passage outside it is provided with on burner body is equipped with external ring fire cover on the ring fire passage outside, and forms the outer shroud fire burns chamber of annular.This burner is characterised in that, the outside sealing in outer shroud fire burns chamber, and the inboard of ring fire combustion chamber is provided with outer ring fire fire hole outside.This burner can make firepower concentrate, and has improved the thermal efficiency thus to a certain extent.But still there is the sufficient inadequately problem of fuel gas buring in this burner.And for example the patent No. is that the Chinese utility model patent of ZL200920146210.6 discloses a kind of burner that is used for gas-cooker; It comprises air distribution disk, external ring fire cover and interior ring fire lid; Also comprise another air distribution disk that is arranged on the employing three-cavity structure between air distribution disk and the interior ring fire lid, thereby increased the volume that auxiliary air replenishes, make that the burning of combustion gas is more abundant; Simultaneously; The combustion system that swingfire and hole fire combined in the fire lid of this burner adopted makes heat energy more concentrated, has improved the thermal efficiency.This burner can improve the thermal efficiency greatly through replenishing auxiliary air, but the setting of air distribution disk makes the structure of burner comparatively complicated, has strengthened the manufacturing cost of burner.
The utility model content
The utility model technical problem to be solved is to above-mentioned prior art, offers a kind of compact conformation, can effectively improve efficiency of combustion, reduces the burner fire lid of fume emission.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this burner fire lid, and the sidewall of said fire lid is provided with fire output hole, and it is characterized in that: said fire covers near said fire output hole position and also is provided with at least one auxiliary air complementary apertures.
Preferably, an end opening of described auxiliary air complementary apertures is located at the inboard facade of said fire lid, and the other end opening of auxiliary air complementary apertures is located at the outer side elevation of said fire lid.Like this, can flow out the smooth circulation of maintenance air from the opening part of the outer side elevation of fire lid smoothly after the auxiliary air opening part that covers inboard facade from fire flows into.
Further preferred, described auxiliary air complementary apertures is four and evenly distributes along the sidewall border level of fire lid.Like this, can replenish auxiliary air better, make burning more abundant.
Described auxiliary air complementary apertures can adopt multiple shape, and is preferred, the consistent and equal slivering shape of described auxiliary air complementary apertures openings at two ends size.Because the restriction of fire lid size and structure, the height of auxiliary air complementary apertures is inevitable very low, thus opening is designed to strip, but the area of enlarged opening, thus auxiliary air effectively replenished.
Further preferred, described auxiliary air complementary apertures is positioned at the top of said fire output hole.Like this, being more conducive to that the flame root is carried out auxiliary air replenishes.
Compared with prior art; The advantage of the utility model is: be provided with at least one auxiliary air complementary apertures at the fire lid near the fire output hole position; The auxiliary air complementary apertures can make near the flame root at the fire output hole place required auxiliary air of aftercombustion better; Impel burning more abundant, improve efficiency of combustion, reduce toxic emission.In addition, cover at fire that to process the auxiliary air complementary apertures more or less freely, and the overall structure of fire lid is comparatively compact, can not complicate because of the setting of auxiliary air complementary apertures.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the cutaway view of burner fire lid shown in Figure 1;
Structural representation when Fig. 3 is applied to gas kitchen ranges for burner fire lid shown in Figure 1.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2; The fire output hole 1 of this burner fire lid is distributed on the border of fire lid sidewall; Simultaneously, the sidewall border along continuous straight runs at the fire lid is evenly equipped with four auxiliary air complementary apertures 2, the inboard facade 3 that an end opening of auxiliary air complementary apertures 2 covers in fire; The other end is opened on the outer side elevation 4 of fire lid, and auxiliary air complementary apertures 2 is located at the top near fire output hole 1 place.During the utility model work, flame 5 is from fire output hole 1 ejection, because the existence of auxiliary air complementary apertures 2; Can make cold and hot air stratification; Because the flame envelope temperature of flame 5 is high, air can be introduced through auxiliary air complementary apertures 2 and add to flame envelope root (flow direction of auxiliary air is shown in the arrow among Fig. 2), impels the flame 5 roots required auxiliary air of aftercombustion better; Make burning more abundant; Improve efficiency of combustion, reduce the discharging of materials such as carbon monoxide, nitrogen oxide in the combustion process, thereby the flue gas that produces in the combustion process also is effectively controlled.In the present embodiment, the structure of four auxiliary air complementary apertures 2 is identical, and its both ends open all is designed to strip, replenishes more effectively flame 5 roots are carried out auxiliary air.Certainly, in process, can regulate the shape or the area of the opening of auxiliary air complementary apertures 2 according to the size of design power.
As shown in Figure 3, present embodiment is the external ring fire cover 7 that is installed in the embedded gas kitchen ranges 6 of family expenses, and interior ring fire lid 8 is installed in the center position of external ring fire cover 7, and pan bracket 9 is placed on outside the external ring fire cover 7, and cooking ware 10 is placed on the pan bracket 9.During gas kitchen ranges 6 work, through auxiliary air complementary apertures 2, in flame 5 combustion processes, replenished auxiliary air better, made burning more abundant, efficiency of combustion is higher.In addition, it is pointed out that the present embodiment scope of application is wider, can be applicable to the gas kitchen ranges of any source of the gas.
The above is merely the preferred implementation of the utility model; Should be pointed out that for those of ordinary skills, do not breaking away under the principle prerequisite of the utility model; Can implement novel make multiple modification or improvement to this, these all are regarded as within the protection domain of the utility model.
