Abstract

The utility model discloses an outer ring fire cover of a gas burner. The outer ring fire cover comprises an outer ring fire cover ring. An inner ring above the outer ring fire cover ring is provided with a ring-shaped downwards-concave conical surface. A circle of outer ring upper fire holes are formed in the ring-shaped downwards-concave conical surface. An outer ring fire cover lower cylindrical wall is arranged at the lower part of the outer ring fire cover ring. An outer ring lower fire groove is arranged on the bottom surface of the outer ring fire cover lower cylindrical wall. Since the circle of outer ring upper fire holes are formed in the ring-shaped downwards-concave conical surface of the outer ring fire cover ring and are circular holes and the outer ring lower fire groove is arranged at the lower part of the outer ring fire cover ring and is an inclined trapezoidal groove, after gas and air are mixed through a mixing chamber, swirling-flow gas is produced and is combined with directly-sprayed gas, the gas is fully burnt in oxygen during burning and the content of carbon monoxide in smoke is lower. Since the burning if more full, more energy is produced; and since the outward diffusion loss of heat is less, more heat is absorbed when the same quantity of heat is produced, i.e. more energy is converted and the thermal efficiency is higher.

Description

A kind of external ring fire cover of gas burner
[technical field]
The utility model relates to a kind of external ring fire cover of gas burner.
[background technology]
Along with the raising of living standards of the people, broad masses of the people are more and more higher to the requirement of domestic environment, require the family kitchen hall.Therefore, household gas utensils have entered huge numbers of families in recent years, have obtained consumers in general's welcome.Existing burner generally all is provided with interior ring fire and outer ring fire on external ring fire cover, interior ring fire is generally to adopt straight flame, is auxiliary fire, for homogeneous heating; Outer ring fire is generally big fire, be main fire, have plenty of swirl flame, have plenty of straight flame, no matter be swirl flame or straight flame, all wish and fully to burn, thereby improve the thermal efficiency, but only change the shape size of glory hole, be difficult to solve problem that fully burning improves the thermal efficiency: 1. because combustion gas can not fully be burnt with oxygen in combustion process, in flue gas, carbon monoxide content is very high, causes burning insufficient, the heat of combustion gas is not fully discharged;
2. in application facet, because combustion gas main fire in combustion process spreads to surrounding, the heat of taking away is many, does not utilize.
To sum up state two kinds of reasons, so the household gas utensils thermal efficiency ratio is lower, energy waste is also many.
[utility model content]
The purpose of this utility model is to overcome the weak point of above technology, and a kind of sufficient combustion is provided, and thermal loss is few, and the thermal efficiency is high, the external ring fire cover of the gas burner of energy savings.
The purpose of this utility model is achieved in that
A kind of external ring fire cover of gas burner, it is characterized in that it comprises the outer ring fire decorative cover, be equipped with the annular recessed conical surface in outer ring fire decorative cover top, the recessed conical surface of annular is provided with fire hole on a circle outer shroud, the bottom of outer ring fire decorative cover is provided with barrel under external ring fire cover, and under external ring fire cover, the bottom surface of barrel is provided with fiery groove under outer shroud.
The external ring fire cover of a kind of gas burner as above, the bottom surface that it is characterized in that barrel under described external ring fire cover comprises diapire and the annular fovea superior conical surface of annulus platform shape, under outer shroud, fiery groove is arranged on the diapire and the annular fovea superior conical surface of annulus platform shape.
The external ring fire cover of a kind of gas burner as above is characterized in that on described outer shroud, fire hole is circular hole.
The external ring fire cover of a kind of gas burner as above is characterized in that under described outer shroud, fiery groove is skewed slot.
As above require described a kind ofly, it is characterized in that the stop collar that the bottom of described outer ring fire decorative cover coordinates with burner, stop collar is arranged on the periphery of fire hole on outer shroud.
The utility model is provided with fire hole on a circle outer shroud at the annular recessed conical surface on the external ring fire cover circle, on outer shroud, fire hole is circular hole, be provided with fiery groove under outer shroud in the bottom of external ring fire cover circle, under outer shroud, fiery groove is the inclined ladder shape groove, after combustion gas and air are mixed through hybrid chamber, the gas and the direct injection gas that produce a kind of spiral-flow type combine, thereby fully burn with oxygen in combustion process, and in flue gas, carbon monoxide content is lower.Because burning is more abundant, make to produce more multi-energy, simultaneously because the outside divergence loss of heat is few, produce the identical more heat of heat absorption, that is to say that power conversion gets more, the thermal efficiency is higher.

[specific embodiment]
A kind of external ring fire cover of gas burner, it comprises outer ring fire decorative cover 1, outer ring fire decorative cover 1 top 10 in be equipped with the annular recessed conical surface 2, the recessed conical surface 2 of annular is provided with fire hole 3 on a circle outer shroud, on outer shroud, fire hole 3 is circular hole, and the bottom of outer ring fire decorative cover 1 is provided with barrel 4 under external ring fire cover, and under external ring fire cover, the bottom surface 41 of barrel 4 is evenly equipped with fiery groove 5 under some outer shrouds, under the outer shroud of stating most, fiery groove 5 is skewed slot, makes fiery groove 5 formation inclined ladder shape grooves under outer shroud.
Under external ring fire cover, the bottom surface 41 of barrel comprises diapire 411 and the annular fovea superior conical surface 412 of annulus platform shape, and under outer shroud, fiery groove 5 is arranged on the diapire 411 and the annular fovea superior conical surface 412 of annulus platform shape.
The stop collar 6 that the bottom of outer ring fire decorative cover 1 coordinates with burner, stop collar 6 is arranged on the periphery of fire hole 3 on outer shroud.
as shown in the figure, when the utility model is arranged on burner 100, burner 100 is connected with interior ring combustion gas and air mixing tube 102 and outer shroud and air air mixture pipe 101, the middle part of burner 100 is provided with interior ring combustion gas mixing chamber seat 103, be provided with the interior ring combustion gas mixing path 10 4 that communicates with interior ring combustion gas and air mixing tube 102 on interior ring combustion gas mixing chamber seat 103, also be provided with the outer shroud combustion gas mixing chamber seat 105 that is located at seat 103 peripheries, interior ring combustion gas mixing chamber on burner 100, outer shroud combustion gas mixing chamber seat 105 is provided with the outer shroud combustion gas mixing path 10 6 that outer shroud combustion gas and air hose 101 communicate.interior ring fire cover 107 covers on interior ring combustion gas mixing chamber seat 103, outer ring fire decorative cover 1 covers on outer shroud combustion gas mixing chamber seat 105, combustion gas enters into outer shroud combustion gas mixing path 10 6 on outer shroud combustion gas mixing chamber seat 105 from outer shroud combustion gas mixing pipe 101, after being lighted, fiery groove 5 ejections under fire hole 3 and outer shroud from the outer shroud, the gas and the direct injection gas that produce a kind of spiral-flow type combine, thereby fully burn with oxygen in combustion process, in flue gas, carbon monoxide content is lower, because burning is more abundant, make and produce more multi-energy, simultaneously because the outside divergence loss of heat is few, produce the identical more heat of heat absorption, that is to say that power conversion gets more, the thermal efficiency is higher.
