Description
Technical field
The utility model relates to the burner technical field, the burner that especially a kind of Chinese meal air blowing gas cooking stove uses.
Background technology
At present, the hotel, the restaurant, the combustion system of the burner that adopts on the Chinese meal gas cooking stove that use in the dining room is broadly divided into two kinds, a kind of is that long flame-type is an atmospheric burning type, adopt high-power air blast forced air supply to help burning, owing to pursue the vigorous fire notion simply, energy-conservation and the feature of environmental protection of having ignored product, the gas cooking stove of this air blast burner comprises base, gas mixing pipe, air blast, burner, its flame fasciculation from burner is concentrated and is ejected, flame and high-temperature flue gas arrive the frying pan bottom with very big velocity shock, the heat transfer time is short, and gas concentration is high mixes inhomogeneously with combustion air, and it is insufficient to burn, the thermal efficiency of kitchen range is low, it is slow to heat up, time is long, the sooting the bottom of a pan not only wastes energy easily, and air pollution and noise pollution are also very serious; Another kind is that no flame-type is the surface-type burning, is that the infrared ray porous ceramic plate is housed on airtight furnace shell, and combustion gas fully mixes in the hybrid chamber of furnace body with air, and the intensive eyelet by the infrared ceramic plate burns then.Since inspiration in advance enough combustion gas and mixing, so flame is shorter, do not contact the bottom of a pan, flame profile can not be damaged, thereby its burning is abundant relatively.This cooking stove is simultaneously heated body to be heated by convection current and infra-red radiation dual mode, so compare with the normal atmospheric burner, has improved the thermal efficiency greatly.But, the power of this stove and accessory is generally lower, can not adapt to the requirement of Chinese meal very hot oven quick-fried, and in case power is strengthened, be difficult to effectively solve large tracts of land heat energy and assemble the too high lost of life that causes of back infrared ceramic plate temperature, development of heat tempering easily, the contradiction that has potential safety hazard, burner adds the corresponding increasing of size of high-power back infrared ceramic plate on the one hand, because the low cracking easily of its linear expansion coefficient, the handling characteristics of Chinese meal cooking stove is that frying pan is scrubbed continually and had water droplet unavoidably and drip on cooking stove on the other hand, cause the explosion of high-temperature infrared ray ceramic wafer also easilier, and this stove and accessory wherein internal heat power is too concentrated in the small size scope, thereby limited infrared burner promoting the use of on the Chinese meal gas cooking stove greatly.And at present the air blast burner of long flame, atmospheric combustion is still helplessly used in hotel, restaurant, dining room.
Summary of the invention
The purpose of this utility model is to provide that a kind of power is big, combustible gas and combustion air mixes, sufficient combustion, thermal efficiency height, pollution-free, noise is low, is suitable for the floated infrared burner of air blast that uses on the Chinese meal gas cooking stove.
The technical scheme that the utility model is adopted for achieving the above object is:
The floated infrared burner of a kind of air blast, comprise the burner housing that is arranged on the grate, the gas mixing pipe that is connected with the burner housing, the gas mixing pipe outer end is provided with burnt gas valve, gas nozzle, air distribution hole and air blast, be provided with burner, igniting pin in the burner housing, burner is provided with venthole, it is characterized in that: described burner housing top also is provided with gas mixed box, gas mixed box top is provided with the stove circle of band seam, on the stove circle air leaving cover is installed, be provided with the choked flow net between stove circle and the air leaving cover, air leaving cover is provided with the gas outlet.
In order to realize ignition function easily, not influence product appearance and pot, pot etc. overflow can be by cooking time the water again and drench, waterproof, moisture resistance is good, igniting is reliable, and igniting pin described in the utility model is arranged in the gas mixed box.
The surface of choked flow net described in the utility model is provided with infrared coating, and the density of mesh is 20～60 orders.She Ji purpose is like this, can prevent the tempering phenomenon that occurs in the combustion process, make its burning more stable, the surface of choked flow net scribbles infrared coating can make its back that is heated produce infra-red radiation, improve the thermal efficiency, the choked flow net is made with high temperature resistant and oxidation resistant alloy material, to guarantee that it can use for a long time in the barbecue of flame, mesh density is preferably 20～60 orders, mesh is too much, and its blocking effect is not obvious, very few can reduce thermal convection current, reduce the thermal efficiency, also be unfavorable for the abundant burning of combustion gas simultaneously.
More even for combustible gas is mixed with combustion air, make fuel gas buring more abundant, air leaving cover described in the utility model is the arch of epirelief, and the gas outlet that is provided with on the air leaving cover is circumferentially evenly arranged along air leaving cover.
The gas outlet that is provided with on the air leaving cover described in the utility model is a strip, and the long limit of strip and the angle α on air leaving cover base are 45 °～90 °; The angle β of gas outlet and air leaving cover tangent line is 30 °～60 °.She Ji advantage is like this, combustion mixture by the gas outlet ejection is linear rotation type air current injection, enlarged the distribution radius of flame, make flame disperse relatively, can not produce the problem that the center firepower is too concentrated in the small size scope, increase the contact area in the flame and the bottom of a pan, thereby improved heat utilization efficiency.
As further improvement of the utility model, the long limit of described strip and the angle on air leaving cover base are 60 °; The angle of gas outlet and air leaving cover tangent line is 45 °.
The burner housing top of the floated infrared burner of the utility model air blast is provided with gas mixed box, and it is more even that combustible gas is mixed with combustion air; Gas mixed box top is provided with the air leaving cover that is the epirelief arch, the strip that is provided with on the air leaving cover and have the combustion mixture of the gas outlet ejection of certain angle to be linear rotation type air current to spray, enlarged the distribution radius of flame, make flame disperse relatively, can not produce the problem that the center firepower is too concentrated in the small size scope, increase the contact area in the flame and the bottom of a pan, thereby improved heat utilization efficiency; The surface that is provided with between gas mixed box and the air leaving cover scribbles the choked flow net of infrared coating, can prevent from the tempering phenomenon that occurs in the combustion process to make its burning more stable, and improve the thermal efficiency; The electronic ignition pin is arranged in the gas mixed box, and waterproof, moisture resistance is good, igniting is reliable.Therefore the beneficial effects of the utility model are conspicuous.
