Abstract

The invention provides a gas stove burner, and belongs to the field of gas stoves. Traditional gas stove burners are formed by casting cast iron, and the defects that the service life is shortened and potential safety hazards are increased due to the fact that surfaces are easy to oxidize and etch exist. Aluminum alloy is adopted to integrally cast a stove head and an ejection pipe of the burner, hard oxidation treatment is carried out on the surface of the stove head to form a compact hard oxidation layer, the service life of a gas stove can be long, use efficiency can be high, and manufacturing cost is reduced.

Description

A kind of burner for gas stove

Technical field

The invention belongs to gas kitchen ranges field, especially relevant with a kind of burner for gas stove.

Background technology

Gas-cooker mainly comprises air supply system, combustion system and ignition system, wherein combustion system mainly comprises burner, fire hole cover and air regulating board, conventional burner as shown in Figure 1, mainly by the burner 2 being connected as a single entity and induction tunnel 1, formed, four cylinder dividing plates 3 that are projected on furnace end body are set on burner, four cylinder dividing plates are coaxial, fire hole cover comprises the interior fire hole cover of plate-like and the outer fire hole cover of ring-type, interior fire hole cover mounts cover on two cylinder dividing plates that are positioned at inner side and forms internal combustion air cavity, outer fire hole cover mounts cover in two cylinder dividing plates in outside and forms external combustion air cavity, air flue is set on furnace end body and is communicated with induction tunnel inner chamber, for carrying air mixture body from induction tunnel inner chamber to two combustion gas chambeies.When gas-cooker is used, open air supply system, combustion gas enters induction tunnel through duct injection, induction tunnel drainage air becomes air mixture body with combustion gas mixing, air mixture body is conveyed into combustion gas chamber from induction tunnel inner chamber, in combustion gas chamber, in diffusion the fire hole from fire hole cover, emerges, and ignition system igniting.Conventional burner adopts iron casting, fire hole cover is all to manufacture with copper material, copper is hot good conductor, when burning, can produce a large amount of heats, part heat is transmitted on the burner of burner by fire hole cover, make burner when burning, become high temperature, cast iron is very easily oxide etch when high temperature, after oxidized corrosion, on surface, often produce the loose oxide layer of one deck, oxide layer is easily peeled off, the oxide skin of peeling off is easily stopped up air flue, the heat conductivity that adds cast iron is relatively little, cylinder dividing plate is easily broken, so, the burner of burner will shorten service life, and can produce larger gap between burner cylinder dividing plate and fire hole cover, air mixture body is excessive being lighted from gap easily, produce unnecessary burning point, increase potential safety hazard, burning flare on fire hole cover is diminished, reduce gas-cooker service efficiency.

Summary of the invention

Object of the present invention is intended to solve the easy oxidized corrosion of traditional gas kitchen ranges cast iron type burner and the defect of reduction of service life, increase potential safety hazard provides the burner for gas stove that a kind of service life is normal, service efficiency is high.

For this reason, the present invention is by the following technical solutions: a kind of burner for gas stove, comprise the burner and the induction tunnel that are connected as a single entity, and it is characterized in that: described burner adopts aluminium alloy monoblock cast to form, the burner of combustion ball carries out surface hard oxidation processes, forms surface compact hardening oxidation layer.

Use the present invention can reach following beneficial effect: 1. by aluminum alloy materials, to replace cast iron, and hardening oxidation is carried out in burner surface and process the fine and close hardening oxidation layer of formation, make burner surface be difficult for being corroded, guarantee the kitchen range long life, reduced maintenance; 2. aluminium alloy thermal conductivity is better, can conduct heat to induction tunnel more, and the mist in heating induction tunnel reduces mist in the combustion heating process of fire hole cover, improves the efficiency of combustion of burner; 3. the weight of aluminium alloy is lighter, can reduce the weight of burner, in processing course of conveying, can reduce and fall damage, reduces cost of transportation; 4. aluminium alloy casting processing is relatively easy, can reduce manufacturing cost.
