Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
See Fig. 1 ~ Figure 13, the burner being provided with the utility model embodiment comprises central flame cap 1, outer ring fire cover 2, combustion chamber 3 and base 4.
Base 4 comprises main fiery combustion gas induction tunnel 41, central flame combustion gas induction tunnel 42, main fiery Gas Pipe 43 and central flame Gas Pipe 44.Central flame Gas Pipe 44 is sheathed in main fiery Gas Pipe 43, and main fiery combustion gas induction tunnel 41 is communicated with main fiery Gas Pipe 43, and central flame combustion gas induction tunnel 42 is communicated with central flame Gas Pipe 44.
Central flame cap 1 and outer ring fire cover 2 are arranged on combustion chamber 3.
Combustion chamber 3 is arranged on base 4.Offer split channel 31 and central passage 32 in combustion chamber 3, central passage 32 is positioned at the centre of combustion chamber 3, and split channel 31 is positioned at the side of central passage 32.The entrance of split channel 31 is communicated with main fiery Gas Pipe 43, and the entrance of central passage 32 is communicated with central flame Gas Pipe 44.
Outer ring fire cover air cavity 24 is offered, the outlet of outer ring fire cover air cavity 24 and split channel 31 in outer ring fire cover 2.
Have the fire hole 21 of annular at the end face of outer ring fire cover 2, fire hole 21 is arranged around the center of the end face of outer ring fire cover 2.Fire hole 21 is at least two, and these fire holes 21 are in inside and outside setting in the radial direction of end face, and can form the flame of multiple ring-type, inside and outside distribution, heating effect is good; In the present embodiment, these fire holes 21 are arranged with one heart, and flame is more even.Centroclinal to outer ring fire cover 2 of the end face of outer ring fire cover 2, and this end face is high outside and low outside, fire hole 21 is arranged in height in the short transverse of end face, the fire hole 21 of the inside is low, the fire hole 21 of outside is high, and so just with the form fit that centre, the bottom of a pan is low, outside is high, the bottom of a pan flame distribution is even, the height in every ring fire hole exits and the bottom of a pan is consistent, and heating effect is good.The radian of the end face of outer ring fire cover 2 can be close with the radian in the bottom of a pan.
The inside of outer ring fire cover 2 has the passage 23 of annular, and passage 23 is arranged around the center of the end face of outer ring fire cover 2.The cross section of passage 23 is horn-like, and one end that its bore is less is communicated with fire hole 21, and one end that bore is larger is communicated with outer ring fire cover air cavity 24.Passage 23 is at least two, arranges with one heart, and the quantity of passage 23 is identical with the quantity of fire hole 21, the supporting passage 23 of each fire hole 21.Combustion gas in outer ring fire cover air cavity 24 enters fire hole 21 after passage 23, because passage 23 is horn-like, combustion gas from the less one end of its bore out after flow velocity accelerate, the flame of fire hole 21 can be strengthened like this.
Fire hole 21 is directly over outer ring fire cover 2, and such flame is exactly spray directly over outer ring fire cover 2, and directly over outer ring fire cover 2 is exactly the bottom of pot, and like this relative to the flame of the oblique upper of prior art, the utility model efficiency of heating surface is better.
The back side of outer ring fire cover 2 is fixedly installed some protruding reinforcements 22; reinforcement 22 arranges radially; and when applying; namely after the utility model and pan bracket assemble; the reinforcement 22 of the position corresponding with pan bracket pin sheet is larger than reinforcement 22 width dimensions of other position; the reinforcement 22 at this place effectively can block flame like this; prevent flame calcination pan bracket pin sheet; not only can protect pan bracket pin sheet, also can prevent the situation producing CO because flame contact pan bracket pin sheet causes burning insufficient.
After outer ring fire cover 2 top offers the fire hole 21 of many group annulars, it is divided comes, and just needs to connect as a whole by reinforcement 22, strengthen intensity between each several part.
In addition, it should be noted that, the specific embodiment described in this description, the shape, institute's title of being named etc. of its parts and components can be different, and the above content described in this description is only to the explanation of the utility model structure example.
