Technical field
This utility model relates to the distributor fire cover of a kind of burner with high efficiency.
Background technology
I discloses a kind of burner with high efficiency assembly on April 17th, 2013 in Chinese patent literature CN202884919U, including distributor and the burner gas separating seat corresponding with distributor gas circuit, its distributor is connected with airway, distributor forms flame of centre layer with the airway being positioned at center, and distributor forms external flame layer with peripheral airway；External flame layer is at least divided into two-layer, and distributor includes that distributor upper cover and distributor lower cover, distributor upper cover and distributor lower cover repeat to be stacked up and down.Distributor also includes that the distributor middle cover being arranged between distributor upper cover and distributor lower cover, distributor upper cover and distributor middle cover form one layer of external flame layer, and distributor middle cover and distributor lower cover form other one layer of external flame layer.This utility model increases the burning area of flame, eliminates or reduces flame covering (kitchen range) blank, being greatly improved the combustion power of burner assembly, improve the thermal efficiency, reduce discharge amount of exhaust gas, have the environmental protection effectiveness of energy-saving and emission-reduction.
The position of the corresponding each spacing head of its distributor upper cover arranges the circular arc male part of about four point of three circle, uses long arc shape male part transition between circular arc male part；The shape of this fire cover, when can cause fuel gas buring, the angle direction of flame is on the low side, cause drip tray or the cooker racks easily burning on body of heater, thus wasted heat, the most easily make body of heater turn black, the most this fire cover is when than relatively low high combustion, this problem becomes apparent from, and the application will be further improved in above-mentioned patent, to solve the problems referred to above.
Utility model content
The purpose of this utility model aims to provide a kind of simple in construction, firepower is more concentrated, combustion gas is more abundant, flame combustion angle higher burner with high efficiency assembly apparatus, to overcome weak point of the prior art.
By the distributor fire cover of a kind of burner with high efficiency that this purpose designs, including the upper cover being stacked up and down and lower cover, two lids are tabular, the periphery of upper cover is radial along its center is provided with some spacing head bore, the periphery of lower cover is radial along its center is provided with several combustion gas through holes, each spacing head bore is arranged in groups with corresponding combustion gas through hole, on, unsettled being stacked of lower cover is collectively forming the groove position for fuel gas buring, its architectural feature is, the position at the corresponding each spacing head bore place of the outer rim of upper cover is provided with the male part of arc-shaped, excessively connected by the inner fovea part of arc-shaped between adjacent arc male part；The outer shape of lower cover plate body is suitable with the outer shape of upper cover plate body, and the overall dimensions of lower cover plate body is more than the overall dimensions of upper cover plate body；After upper and lower cover is stacked, the cross section at they both ends is stepped.
The described inner fovea part being positioned at upper cover is provided with secondary recess.
The outer circumferential position of the described male part being positioned at upper cover is provided with some projections for increasing groove position gas circulation, protruding with place spacing head bore for the outer circumferential position of the radial male part being laid in upper cover in the center of circle on.
Described upper cover central part is provided with installing hole, and lower cover central part is provided with cross installing rack, and installing hole is provided with downward flange, and flange puts in installing rack, makes upper and lower cover be integrally fixed.
Described flange is connected by welding and cross installing rack are fixing.
Having downwardly extended several button portions bottom described flange, button portion is downwardly convex step-like, and button portion is fastened with cross installing rack through bending.
The beneficial effects of the utility model are:
By improving upper cover and the outer rim shape of lower cover, when making fuel gas buring, flame level the most consumingly rushes (flame height is close to 0 degree) outward, thus it is effectively improved the cut direction of flame, so that the burned angle of flame higher (flame height be more than 10 degree), it is to avoid flame burns in drip tray or cooker racks, and flame can concentrate on pan base burning, the heat of flame will not be wasted, also effectively prevent body of heater blackout phenomenon.

Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is further described by embodiment.
First embodiment
See Fig. 1-Fig. 2, the distributor fire cover of this burner with high efficiency, including the upper cover 1 being stacked up and down and lower cover 2, two lids are tabular, the periphery of upper cover 1 is radial along its center is provided with some spacing head bore 11, the present embodiment totally four spacing head bore 11, the dress arrangement in cross, the periphery of lower cover 2 is radial along its center is provided with several combustion gas through holes 21, each spacing head bore 11 is arranged in groups with corresponding combustion gas through hole 21, on, unsettled being stacked of lower cover is collectively forming the groove position for fuel gas buring, the position at corresponding each spacing head bore 11 place of the outer rim of upper cover 1 is provided with the male part 12 of arc-shaped, excessively connected by the inner fovea part 13 of arc-shaped between adjacent arc male part 12；The outer shape of lower cover 2 plate body is suitable with the outer shape of upper cover 1 plate body, and the overall dimensions of lower cover 2 plate body is more than the overall dimensions of upper cover 1 plate body；After upper and lower cover is stacked, the cross section at they both ends is stepped.By this technical scheme, when making fuel gas buring, flame rushes the most outward, thus be effectively improved the cut direction of flame, so that the burned angle of flame is higher, it is to avoid flame burns in drip tray or cooker racks, the heat of flame will not be wasted, also effectively prevent body of heater blackout phenomenon.
Additionally, in order to increase gas circulation, the flame making fuel gas buring is more prosperous, combustion power is bigger, can the most by the following technical solutions, the outer circumferential position of the male part 12 being i.e. positioned at upper cover 1 is provided with some projections 121 for increasing groove position gas circulation, protruding 121 with place spacing head bore 11 for the outer circumferential position of the radial male part 12 being laid in upper cover 1 in the center of circle on.
