Description

A kind of combustion-assisting gas burner

Technical field

The present invention relates to the gas burner field, especially a kind of combustion-assisting gas burner.

Background technology

Gas burner is the important component part of commercial gas-fired stove, its structure comprises a cylindrical shell as hybrid chamber, and the combustion chamber and the firing device that is positioned at combustion chamber one side or center that are positioned at the cylindrical shell top, the below of cylindrical shell is connected to air inlet and air inlet, and the intake stack between air inlet and the cylindrical shell hybrid chamber is provided with spherical valve.And the working method of the burner that most of in the market gas kitchen ranges adopt is: the combustion gas of igniting arrives the combustion chamber place by pitot tube, burning under the igniting of naked light.Main combustion gas is arrived fast to be ignited behind the combustion chamber by mix cylinder and ignites under the effect of air inlet wind-force; Gaseous mixture burns above combustion chamber and is used for food in the heating kettle.Its deficiency is: the discovery gaseous mixture burns above combustion chamber and is kermesinus in 1, using, and a large amount of ember are overflowed by the pot both sides, and this burner makes mixture combustion insufficient when work, and ember can not utilize again.2, original combustion chamber is a cylindrical-shaped structure, because the combustion chamber centre position is provided with the air nozzle of igniting, so the intake in the middle of the combustion chamber is less, and the intake of outer ring is bigger, therefore causes burning inhomogeneous.3, because the cylindrical shell hybrid chamber is an airtight cavity, there is not steam vent in the original structure; 2, water can enter airtight cylindrical shell along the aperture in the combustion chamber, and can't discharge.

Summary of the invention

The objective of the invention is to overcome the deficiency of above-mentioned existence, and a kind of combustion-assisting gas burner is provided, be widely used in places such as social food and drink, government, enterprises and institutions' authority canteen, restaurant.

The objective of the invention is to finish by following technical solution.This combustion-assisting gas burner, mainly comprise combustion chamber and cylindrical shell, form main hybrid chamber in the cylindrical shell, main tracheae is connected with main hybrid chamber by main tracheae nozzle, described combustion chamber is provided with one group of mouth of igniting, and wherein an epitaxial lateral overgrowth in combustion chamber centre position is stretched and formed a boss; Opposite side stretches out and forms the hybrid chamber of igniting; Be provided with round table-like cumulative plate in the main furnace chamber outside the combustion chamber 1, the cumulative plate hole on the cumulative plate is connected with exhaust smoke hole by the smoke extraction chamber in the stove circle; The end of air nozzle of igniting is connected with the air inlet pipe of igniting, and the other end of the air nozzle of igniting extends in the hybrid chamber of igniting.

As preferably, the radial direction to inner ring reduces mouthful diameter of igniting of described combustion chamber along the outer ring.

As preferably, described boss is cylindrical shape, and connects into an overall structure with combustion chamber.

As preferably, the main hybrid chamber bottom in the described cylindrical shell is connected with air inlet by blast pipe, is provided with the globe valve that is used for unidirectional air intake in blast pipe, has leakage hole on the close blast pipe inwall bottom position of air inlet of globe valve.

As preferably, the tube end of described cylindrical shell bottom the inwall of blast pipe on same horizontal plane.

As preferably, described stove circle is round table-like, is provided with exhaust smoke hole at the tip position of stove circle.

As preferably, the described air nozzle of igniting is provided with air-jet cover.

As preferably, form main hybrid chamber and secondary hybrid chamber by demarcation strip in the described cylindrical shell, main hybrid chamber is formed at the bottom of demarcation strip, and the lower space of demarcation strip top and combustion chamber forms secondary hybrid chamber.

The effect that the present invention is useful: 1, form a boss because an epitaxial lateral overgrowth in combustion chamber centre position is stretched, although the intake in the middle of the combustion chamber is less, and the intake of outer ring is bigger, but boss is near from the bottom of a pan, and the combustion chamber outer ring is far away far from the bottom of a pan, and after the two was balanced compensated, burning was just very even.2, since at globe valve near having leakage hole on the blast pipe inwall bottom position of air inlet, therefore can play the effect of exhaust, avoid blower fan overheated and burn out during return air, the ponding of closed cylinder hybrid chamber can be discharged by this leakage hole in addition.
