Technical field
Utility model relates to the gas-cooker technical field of burner, relates in particular to a kind of gas-cooker burner that fuel gas buring is more abundant and the center nonflame heats that makes.
Background technology
At present, the employed burner of gas-cooker mainly contains two classes, one class is partly-premixed flaming combustion device, wherein the flame of internal heat lid can interfere easily with outer fire cover flame inwardly, it is insufficient to cause auxiliary air to supply with, cause flame to elongate, the bottom of a pan can not make full use of the high-temperature region of flame, and the thermal efficiency is generally not high; Another kind ofly be aphlogistic infrared burner for inner and outer ring, infrared burner utilizes heat radiation that heat energy sends to heated object, although the thermal efficiency is higher, exists thermic load low, generally have only about 3.3Kw, and big to thermal radiation of body, start and wait defective slowly.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and provides a kind of simple and reasonable for structure, possesses simultaneously poly-burning in flame and the nonflame is arranged, the gas-cooker burner of homogeneous heating, center nonflame heating that the thermal efficiency is high.
The technical scheme that its technical problem that solves the utility model adopts is: the gas-cooker burner of a kind of center nonflame heating, in comprising, outer induction tunnel, in, outer induction tunnel one end is provided with gas inlet, the other end is in correspondence is connected with respectively, outer burning passage, it is characterized in that, in described, in outer burning passage top end opening is covered with respectively, outer fire cover, in, be provided with the secondary air inlet annular passage between the outer fire cover, have the fire hole that communicates with outer burning passage on the outer fire cover, inner fire cover is the infrared ray flameless combustion plate, has a plurality of heat radiation holes that communicate with the internal combustion passage on the infrared ray flameless combustion plate.The gas-cooker burner of this structure, combine by traditional have flame outer fire cover and nonflame infrared heat radiation inner fire cover structure, because it is low that the thermic load of inner fire cover requires, so by the infrared ray flameless combustion plate is set at inner fire cover, this infrared ray flameless combustion plate is after burning reaches uniform temperature, meeting produces the infrared heat radiation to top heated object bottom, reaches to add thermal effect, and its thermal efficiency is higher; The more important thing is, make the flame of outer fire cover can make full use of the auxiliary air of the secondary air inlet annular passage between the inside and outside fire lid, the height of the fire hole flame of outer fire cover is shortened, avoid flame to interfere, thereby reach the high-temperature region that makes full use of flame, reach the purpose that improves the thermal efficiency.
The utility model can also adopt following technical measures to solve: as further improving, described fire hole comprises that being arranged on the outer fire cover inner conical surface evenly lays the flute profile fire hole that is divergent shape towards outer fire cover central circular fire hole, trapezoidal fire hole and outer fire cover end face, flute profile fire hole center line and horizontal plane constitute angle, circular fire hole, trapezoidal fire hole can make full use of the auxiliary air mixed combustion of secondary air inlet annular passage, thermal efficiency height.
Described circular fire hole, trapezoidal fire hole and flute profile fire hole all are distributed on the outer fire cover by circumferencial direction, manufacturing process tradition, low cost of manufacture.
Described infrared ray flameless combustion plate is a metal plate, has a plurality of openings heat radiation holes up on the metal plate.
Described infrared ray flameless combustion plate is a ceramic laminate body, has a plurality of openings heat radiation holes up on the ceramic laminate body.
The beneficial effects of the utility model are: the gas-cooker burner of a kind of center of the present utility model nonflame heating, it is simple in structure, rationally, combine by traditional have flame outer fire cover and nonflame infrared heat radiation inner fire cover structure, because it is low that the thermic load of inner fire cover requires, so by the infrared ray flameless combustion plate is set at inner fire cover, the internal combustion passage premixed combustion of combustion gas below the infrared ray flameless combustion plate, this infrared ray flameless combustion plate is after burning reaches uniform temperature, can produce the infrared heat radiation to top heated object bottom, reach and add thermal effect, its thermal efficiency is higher; The more important thing is, make the flame of outer fire cover can make full use of the auxiliary air of the secondary air inlet annular passage between the inside and outside fire lid, the height of the fire hole flame of outer fire cover is shortened, avoid flame to interfere, thereby reach the high-temperature region that makes full use of flame, reach the purpose that improves the thermal efficiency.

Fig. 2 is the profile of A-A among Fig. 1.
Fig. 3 is the profile of B-B among Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1 to Figure 3, the gas-cooker burner of a kind of center nonflame heating, in comprising, outer induction tunnel 1,2, in, outer induction tunnel 1,2 one ends are provided with gas inlet 3, the other end is in correspondence is connected with respectively, outer burning passage 4,5, in described, outer burning passage 4, in 5 top end openings are covered with respectively, outer fire cover 6,7, in, outer fire cover 6, be provided with secondary air inlet annular passage 8 between 7, have the fire hole that communicates with outer burning passage 5 on the outer fire cover 7, inner fire cover 6 is the infrared ray flameless combustion plate, has a plurality of heat radiation holes 601 that communicate with internal combustion passage 4 on the infrared ray flameless combustion plate.
