Abstract

A fierce-fire gas stove is provided. Wherein, when any combustible gas injects into a gas-mixing pipe through a nozzle, the ''wind resistance'' in the gas-mixing pipe reduces the flow of the combustible gas and changes the flowing direction of the gas; adjusting the up and down position of the air-distribution pipe that is located out the gas-mixing pipe can adjust the intake volume of the air, so that the mixture proportion of the combustible gas and air will reach the best level. When the combustible gas flows out from the air-out port of the gas-mixing pipe, by a fire-distribution head, the combustible gas will be distributed in an equal way all around; the fire-guide groove at the plane or spherical surface at bottom of the fire-distribution head changes effectively the flowing direction of the combustible gas, so that the combustible gas generates rotary flowing. A fire-guide ring located at the outside of the air-out port of the gas-mixing pipe distributes the combustible gas in a radiation way upward along the inclined plane of the fire-guide ring. Under such a condition, the combustible gas combusts and forms a dish-like flame similar to a pot, so that the flame will be distributed in a bigger area in a balanced and effective way. Adjusting the distance between the fire-distribution head and the fire-guide ring can adjust the size of the distribution area of flame. The utility model improves thermal efficiency about 55% (only about 25% for prior technology), and saves more than 50% energy.

Description

Intense fire gas cooker

Technical field

The utility model relates to the intense fire gas cooker of similar site's culinary art uses such as dining room.

Background technology

Intense fire gas cooker be meant similar site such as dining room need heat firepower comparatively fierce be the gas-cooker of fuel with the fuel gas.At present, the fuel gas gas-cooker that similar site such as dining room use mostly adopts annulus tubulose porous type gas-cooker, this type of gas-cooker has an annulus tubulose fuel gas passage usually, a Perforated decking that shape is similar substantially to the annulus tubular conduit is arranged above gas passage, fuel gas is after admission line enters the annulus tubular conduit, be full of channel space, and flow out and burning from the through hole of Perforated decking.Flow velocity was slack-off after the fuel gas of this porous type gas-cooker entered the annulus tubular conduit from admission line, the through-hole aperture of Perforated decking is less (because number of openings is more, the aperture can not be too big), flow velocity was slower after fuel gas flowed out from through hole, combustion flame is softer, therefore, burning fire power is little.Simultaneously, at the fuel gas inflow entrance air intlet is set because this type of gas-cooker adopts, makes fuel gas air distribution deficiency, it is insufficient to burn, and heat-energy losses is serious in the heat transfer process in addition, and the heat energy utilization rate is low.Usually this type of gas-cooker consumes gas very much, and the thermal efficiency only is about 25%, is difficult to surpass 30%.

A kind of " single head formula " gas-cooker is arranged in the prior art, technology that this gas-cooker has adopted " straight spray " of the prior art, fuel gas arrives the wireway top by wireway " straight spray ", the wireway top is provided with distributor, distributor is positive taper, connects and with its support by a connecting rod that is fixed on the wireway inwall.The effect of distributor is that the gas that wireway " spray " is come out is radial outflow, makes the acutely burning at short notice of quick effluent air, has increased flame temperature, has strengthened firepower, increases with respect to traditional gas cooker energy saving effect.But this " single head formula " gas-cooker also exists firepower too to concentrate, heating is uneven, noise stops burning more greatly, easily and to defectives such as source of the gas and pressure adaptation differences.

Summary of the invention

The utility model proposes a kind of intense fire gas cooker, " straight spray " technology based on prior art is provided with aid distributing pipe and windage in mixed airway lower end, is provided with screw-like swirling flow line at mixed airway inwall, is provided with distributor at the port of giving vent to anger of gas mixing pipe.

Being arranged on the aid distributing pipe that mixes the airway lower end is enclosed within the outer wall that mixes airway and can regulates upper-lower position.

Distributor comprises parts such as fire guiding ring, pilot pin, spacer and distributor.The tabular fire guiding ring of annulus is installed in the gas mixing pipe outside of port and angled with the gas mixing pipe axis of giving vent to anger, pilot pin links to each other with spacer and is fixed on the fire guiding ring, but distributor is installed on the pilot pin and up-down adjustment, the gap of giving vent to anger is formed with fire guiding ring top in the distributor bottom, and distributor base plane or sphere are provided with spiral helicine fire-guiding channel.

The screw-like swirling flow line that mixes the airway inwall can be distributed in whole mixed airway inside and also can only be distributed in place, mixed airway gas outlet.Can adopt the external diameter of packing in gas mixing pipe " spring " close with the gas mixing pipe internal diameter to form, the steel wire of different with common " spring " is two terminations of this " spring " does not form the plane, but keeps screw-like.Select the steel wire diameter and the flight lead of coiling " spring " can adjust the swirling flow effect of swirling flow line to gas.

The main effect of windage is the flow velocity that slows down fuel gas in the gas mixing pipe, and fuel gas produces rotational flow simultaneously, to improve fuel gas and Air mixing efficient.Grouping can be adopted simple hooked shape structure, also can adopt the propeller-like structure, can also adopt fenestral fabric.

Adopt utility model vigorous fire stove, when fuel gas when nozzle sprays into gas mixing pipe, " windage " in the gas mixing pipe reduced the flow velocity of high pressure fuel gas and changed the gas flow mode and the flow direction, the inlet that the upper-lower position of the outer aid distributing pipe of adjusting gas mixing pipe can be regulated air makes fuel gas and Air mixing ratio reach best.Fuel gas is given vent to anger port when flowing out from gas mixing pipe, under the effect of distributor with the fuel gas balance to around distribute, and the fire-guiding channel on distributor base plane or the sphere changes the flow direction of fuel gas effectively, makes fuel gas produce rotational flow.Be positioned at gas mixing pipe give vent to anger the port outside fire guiding ring again with fuel gas equably along the fire guiding ring inclined-plane upwards radiation distribute.Fuel gas burns under this state and has formed the dish-shaped flame of a similar pot shape, and flame equilibrium in bigger area is distributed effectively.Regulate the size that the distance between distributor and the fire guiding ring can be regulated the flame distribution area.

Adopt utility model vigorous fire stove to solve defectives such as prior art annulus tubulose porous type gas-cooker vigorous fire stove fire power is little, the thermal efficiency is low, solve defectives such as prior art " single hose " vigorous fire stove fire power is too concentrated, noise stops burning greatly and easily again, really realized the technological break-through of fuel gas vigorous fire stove.

The utility model vigorous fire furnace thermal efficiency has been brought up to about 55% (prior art is about 25%), energy-conservation reaching more than 50%.
