Abstract

A gas stove burning device comprises an air supply box with an air hole and a spray head which is provided with a fire hole and arranged in the inner chamber of the air supply box. The improvement lies in that a hydrocyclone is arranged at the upper end opening of the air supply box; the upper part of the inner chamber of the hydrocyclone is semi-spherical, while the lower part is cone-shaped, with a compaction ring on the joint position; the angle between the air hole and the horizontal plane and the angle between the fire hole and the horizontal plane are all 20- 40 degrees; the center lines of the air hole and the fire hole are respectively provided with eccentric distance from the axis of the air supply box and the axis of the spray head, with consistent rotating direction. The utility model is used in the cooking of medium cooking stoves, large kitchen ranges and group stoves; the air forms swirl together with the fuel and is mixed fully with the duel for complete combustion, leading to strong fire power and high efficiency; therefore, the utility model can meet special requirements in making Chinese dishes, save energy and reduce emission of harmful gas.

Description

The gas-cooker burner

Technical field

It is the burner of fuel with combustible gas that the utility model relates to a kind of, is applicable to air blast spiral-flow type combustion gas group kitchen range.

Background technology

The core of gas-cooker is a burner, the burner that is used for group's kitchen range, Chinese meal stove, large stove at present mostly is the air blast mixed-flow, and air is sent into air compartment by air blast, and the wind hole on the air-supply box enters the box chamber again, gas-flow is introduced by the fire hole on the shower nozzle, enters the burner hearth burning after both mix.The air-supply box end suitable for reading of existing burner has a banking fire circle; wind hole and horizontal plane have the inclination angle; and with air-supply box eccentric axis apart from being f; fire hole then is horizontally disposed with; and with the shower nozzle axes intersect; eccentric throw is zero; thereby mist is difficult to form eddy flow, and mixability is not enough, can not go out the banking fire circle very soon; often form " smouldering "; consequently burn insufficient, firepower is not violent, is difficult to satisfy the culinary art requirement of food dish, also waste energy simultaneously; do not reach the toxic emission requirement of standard code, influence environmental protection.

The utility model content

The purpose of this utility model is to overcome weak point of the prior art, provide a kind of combustion gas and air of making to form eddy flow, fully mix, improve flow velocity, reach completing combustion, firepower is violent, thermal efficiency height is guaranteed dish culinary art requirement, saves the energy simultaneously, reduce toxic emission, environmental group's gas-cooker burner.

The technical solution of the utility model is: the gas-cooker burner comprises the air-supply box that is provided with the wind hole and is positioned at the shower nozzle that is provided with fire hole of its inner chamber, improvements are that air-supply box upper port is provided with cyclone, the inner chamber of this cyclone is divided into the upper and lower part, top is hemispherical, the bottom is coniform, and both have shrink-ring in the junction.The outlet in described wind hole is towards oblique upper, be that the wind centerline hole is except that having the inclined angle alpha with horizontal plane, with air-supply box axis eccentric distance e is arranged, the outlet of described fire hole is towards oblique upper, be that fire hole center line and horizontal plane have angle of inclination beta, with the shower nozzle axis eccentric throw c is arranged, the fire hole outlet forms same rotation direction with the wind hole exits, and fire hole is positioned at above-mentioned shrink-ring position.

As further improvement of the utility model, above-mentioned α=β=20 °～40 °; The wind hole is arranged in upper and lower 3～5 rows on the box in air-supply, the upper and lower misarrangement row that begin to rehearse, and last round footpath is greater than following round directly; Fire hole is lined up upper and lower two rows on shower nozzle, staggered, and last round footpath is less than round footpath down, eccentric throw c=4～10mm, and go up the round eccentric throw less than round eccentric throw down; There is cap shape ledge in the outside, shower nozzle upper end; Cyclone shrink-ring diameter is 1.2～1.8 with the ratio of shower nozzle external diameter.

Adopt technique scheme, because the outlet of wind hole and fire hole makes the air of ejection and combustion gas form eddy flow in the same way all towards oblique upper, fully mix, suitable inclination angle makes the mixability of air-flow better.Set up cyclone in air-supply box upper port, its effect is that air is when flowing through shrink-ring, flow velocity increases, pressure reduces, and the outlet of fire hole is just at the shrink-ring position, help the quick introducing of combustion gas like this, make gaseous mixture form one " climbing power " and " revolving force ", increase air inflow and mixed effect; Gaseous mixture is expansion rapidly behind shrink-ring, guarantees fully to mix stable lighting, avoid the deflection of flame, fire hole becomes two rows, and last round footpath is less than following round footpath, hole count also is less than round number down, and its area only accounts for 10～15% of the fire hole gross area, mainly plays ignition action; Arrange the supply of fire hole assurance combustion gas down.There is cap shape projection in the outside, shower nozzle upper end, its effect is further to strengthen combustion gas and Air mixing effect, a high temperature gases recirculating district is arranged in the middle of the hemispherical cyclone, recirculating zone diameter d f is less than the shrink-ring diameter d, make flame directly not contact the cyclone inwall, prolonged the service life of cyclone, the recirculating zone also is stable, a strong incendiary source.Mixed airflow is after light in cyclone high temperature gases recirculating district; fiercely go out the inner chamber upper port; enter burner hearth; completing combustion, firepower is violent, the thermal efficiency is high, guarantees particular job requirement of group's kitchen range, Chinese meal stove, large stove; because mixing is abundant, burning is complete; thereby the saving energy, reduce noxious gas emissions such as carbon monoxide, help environmental protection.

Fig. 2 is the eccentric situation schematic diagram in wind hole, and interior hole exits is towards inside front;

Fig. 3 is the eccentric situation schematic diagram of fire hole, and the fire hole outlet is the top toward the outer side.

The specific embodiment

As figure, the air of being sent into by air blast enters air compartment 2 through ajutage 1, and the wind hole 4 on air-supply box 5 enters the box inner chamber again.Air-supply box top is provided with cyclone 8, and its inner chamber bottom is coniform, cone-apex angle θ=30 °, and top is hemispherical, there is shrink-ring two parts junction, hemispherical port diameter and shrink-ring diameter ratio D/d=1.5.Combustion gas is introduced by nozzle 3, and the fire hole 7 on shower nozzle 6 enters cyclone.The angle of wind hole, fire hole and horizontal plane is 30 °, the eccentric throw of wind centerline hole and air-supply box axis, be wind centerline hole place vertical guide with air-supply box axis apart from e=15mm; The eccentric throw c=6mm of fire hole center line and shower nozzle axis.The wind hole becomes the upper and lower three misarrangements row that begin to rehearse, and last round is directly than the round footpath is big down, and fire hole becomes the upper and lower two misarrangements row that begin to rehearse, and last round is directly directly little than following round.The outlet rotation direction unanimity of wind hole, fire hole.Fire hole is arranged on the shrink-ring position, and the shrink-ring diameter is 1.6 with the ratio of shower nozzle external diameter, and there is cap shape ledge 9 in the outside, shower nozzle upper end.
