Abstract

The utility model provides a bar-slot fire-hole burner for a gas stove. The top surface of an ignition ring with a bar slot is a convex cambered cross section, and a plurality of radial bar slot fire holes or bar slot fire holes forming a small cut angle with a spoke wire are evenly distributed on the convex cambered cross section. An injection pipe, a connecting pipe and an annular pressure equalizing chamber are assembled in three separate sections, which is convenient for precision casting and gold processing of an inner wall to reduce the roughness of the inner wall and improve injection ability.

Description

Gas-cooker bar-slot fire-hole burner

The utility model is a kind of neotectonics of gas-cooker bar-slot fire-hole burner.

Present commercially available burner for gas stove, form with all pressing chamber integral body by getting angry circle and induction tunnel, the plane offers bar-slot fire-hole on the ignition circle, this structure exists a little less than the ejaculation of flame dispersing strength, auxiliary air undercompounding, and induction tunnel and annular all press the chamber monoblock cast to cause shortcomings such as inner wall coarse, ejector capacity difference, causes combustibility not ideal enough.

Task of the present utility model is, studies improvement, perfect at above shortcoming, designs a kind of novelty, practicality, the easily manufactured and better gas-cooker bar-slot fire-hole of combustion efficiency burner.

For realizing above task, solution of the present utility model is:

The end face of the bar seam ignition circle [1] of gas-cooker bar-slot fire-hole burner is the convex section, on convex globoidal, be evenly distributed with some radial or the bar-slot fire-hole [1-1] of the one little angle of cut is arranged with the spoke line, the burner induction tunnel is by the induction tunnel [4] of split, tube connector [3], annular all presses chamber [2] to form, induction tunnel [4] tail end socket [4-2] sleeve is connected in the horizontal access [3-1] of tube connector [3], the involutory connection of outlet(discharge) flange [3-2] that the air inlet flange [2-1] that annular is all pressed chamber [2] and tube connector [3] make progress, make annular all press the air inlet of chamber [2] and gas outlet that tube connector [2] makes progress involutory, air regulating port [4-1] is arranged in induction tunnel [4] porch.

Preferred scheme is, the vertical profile of bar-slot fire-hole [1-1] looks to be internal orifice short and collar extension is long, and diffusion type from inside to outside, bar-slot fire-hole [1-1] can be parallel to the bar seam and get angry the center line that encloses [1], also can be made into the oblique angle, make the oblique eddy flow of jet flames.

The utility model is simple in structure, and is easy to process, can reduce induction tunnel, annular roughness of all pressing chamber interior walls, improved the ejector capacity of burner, and combustion gas is mixed with air fully, and the auxiliary air amount is big, and burning has improved the thermal efficiency fully, has reduced blowdown flow rate.

Fig. 1 is the utility model organigram;

Fig. 2 is the bar-slot fire-hole longitudinal sectional view of of the present utility model seam ignition circle;

[1] the bar seam is got angry and is enclosed [1-1] bar-slot fire-hole

[2] annular is all pressed chamber [2-1] air inlet flange

[3] tube connector [3-1] inlet

[3-2] outlet(discharge) flange [4] induction tunnel

[4-1] air regulating port [4-2] socket

Embodiment: referring to Fig. 1, Fig. 2.

Induction tunnel [4] left end porch is provided with air regulating port [4-1] has socket [4-2] to adopt plug bush type to be connected with the horizontal access [3-1] of tube connector [3] at its tail end, tube connector [3] is provided with outlet(discharge) flange [3-2] to the outer rim of upper outlet, annular is all pressed to be had an air inlet to be provided with air inlet flange [2-1] to be involutory with outlet(discharge) flange [3-2] that tube connector [3] makes progress and to be connected under the side direction of chamber [2], annular all presses the bottom surface of chamber [2] to be skewed, its air inlet one side degree of depth is big and the opposite side degree of depth is little, help distribution of air flow, the homogeneity of flame around reaching, the utility model requires induction tunnel [4] and tube connector [3] and annular all to press the interior surface roughness of chamber [2] lower, be designed to three sections split erection methods from the processing technology consideration, both be convenient to hot investment casting, also can carry out the inwall metalworking in case of necessity, reach preferably surface quality and improve its ejector capacity.All press the bar seam ignition circle [1] that is socketed with suitable for reading of chamber [2] in annular, its end face is the convex section, on the convex globoidal of whole circle, evenly offer some of radial bar-slot fire-holes [1-1], Fig. 2 expresses the cross section view of bar-slot fire-hole [1-1], and its internal orifice is short and collar extension is long, is diffusion type from inside to outside, help fuel gas injection and stitch the diffusion of two ends to bar, in order to the mixing and the efficient combustion of auxiliary air, for the natural gas of high heating value or liquefied gas being source of the gas, its effect is obvious especially.Fig. 2 bar-slot fire-hole [1-1] is made radiation direction.The represented bar-slot fire-hole of Fig. 1 [1-1] and radiation intersect an angle, and its side-looking direction bar-slot fire-hole [1-1] is made and got angry the center line of circle [1] with the bar seam and intersect an angle, makes flame produce eddy flow and disperses.
