Burner combined by a plurality of polygon prism cavity fire distributors

Abstract

The invention discloses a burner combined by a plurality of polygon prism cavity fire distributors, which comprises a central pipe and outer ring pipes, wherein the central pipe is positioned at a centre position and the outer ring pipes are annularly arranged at the periphery. The lower ends of the central pipe and the outer ring pipes correspond to a nozzle position of fuel; a sensing needle and an ignition needle are arranged at a position adjacent to the central pipe; the central pipe and the outer ring pipes are polygon prisms; and a through hole on a limiting disc or an air port disc, through which the central pipe and the outer ring pipes pass, are polygons correspondingly, and the polygonal through hole is used for limiting the central pipe and the outer ring pipes. In the invention, as the burner fire distributors are in polygon prism shapes, the burner fire distributors can be conveniently limited by polygon holes at the downside to prevent from rotating along the axial line per se, so as not to result in the situation that the space distribution of the fuel injected by respective fire distributors is uneven.

Description

technical field [0001] The invention belongs to the field of gas stoves, and relates to a combination burner with multiple polygonal prism cavities. Background technique [0002] Currently available gas stoves in the market, all of the burners that adopt a plurality of column cavity sub-firer combinations are cylindrical cavity. See inventor Lin Qingsen's utility model patent "gas stove burner gas mixing conduit assembly" patent number 200320107378.9, utility model patent "gas stove burner lifting structure" patent number: 2003017324.2, utility model patent "a gas stove combustion Device" patent number: 200510042143.X.

AI Technical Summary

Problems solved by technology

The burner combined with multiple cylindrical chamber fire distributors (divided into central fire distributor and outer ring uniform fire distributor) has the following serious defects: the burner combined with multiple cylindrical chamber fire distributors that automatically rises and falls, and its multiple inner The casing assembly fixed on an inner casing assembly disk must be perpendicular to the plane of this disk, and there are multiple cylindrical cavity fire distributors corresponding to the inner sleeve must also be combined and fixed on the cylindrical cavity fire distributor assembly disk, It must also be perpendicular to the plane of the disc, which is very difficult in production and use, and the labor costs and after-sales service costs incurred for this greatly exceed the original intention of the designer.

Otherwise, the opening of the damper is large, and the phenomenon of flame separation during ignition is serious, and the opening of the damper is small. After 3 minutes or even 6 minutes of continuous combustion, the thermal resistance in the burner column cavity at high temperature will reduce the mixed air volume, which will lead to insufficient combustion of the gas. , the content of harmful gases in dry smoke seriously exceeds the standard

In actual use, it is difficult for consumers to manually control the opening of the damper according to the time.

In addition, the experimental research also found that if the combined burner with multiple column chambers only has the injection air mixing effect formed by the gas injection hole directly corresponding to the lower port of the column cavity, it cannot meet the air mixing requirements of the burner at high temperature. When the opening amount is adjusted to the maximum, the harmful gas content in the gas burning dry smoke will still be high

[0004] In the above-mentioned existing column chamber fire distributors, the fire distributor covers are made by cutting or forging metal rods, especially when precious metals such as copper or stainless steel must be used, the amount of materials used and the processing cost are relatively high.
