Abstract
A gas cooker comprises a liquid receiving plate, a furnace end, an inner burner cap, an outer burner cap and an outer ring distributor, wherein an extending hole of a burner is formed in a central boss of the liquid receiving plate; a left-handed or right-handed inner burner groove is formed in the inner ring wall of the outer burner cap; or a left-handed or right-handed inner burner groove is formed in the inner ring wall of the outer burner cap, and an outer burner port is formed in the outer ring wall; the area of the inner burner groove in the outer burner cap is 30-100% of that of the outer burner port. Due to the adoption of the structure, secondary air passes through the gap between the outer ring distributor and the furnace end and enters into the space between the inner burner cap and the outer burner cap, and is in contact with flue gas sprayed from an inner flame hole to achieve the burning process; another secondary air enters from the outer part of the outer burner cap and is in contact with unburned flue gas in the inner flame hole and flue gas sprayed outwards from the outer burner cap to accomplish the complete burning; high-temperature flue gas formed after the flue gas is burned transmits heat to a heating kettle in convection and thermal irradiation manners to achieve heat exchange to accomplish the heating process; the working efficiency is improved.
Description
Technical field
The present invention relates to a kind of cooker burner of internal rotation fire.
Background technology
Present prior art, a kind of interior fireworks cooker burner comprises liquid dish and burner, burner comprises outer fire cover and the outer shroud distributor of burner, inner fire cover, inward turning, described burner comprises that outer shroud mixes air cavity, interior distributor, interior induction tunnel and outer skirt, and interior induction tunnel is communicated with interior distributor, outer induction tunnel is communicated with the mixed air cavity of outer shroud; Burning groove left-handed or that revolve is arranged on the outer fire cover.Existing problems are: when gas flame sprays to the heating kettle center, kitchen range outer shroud inner air is under-supply, cause most of gas flame can not in time touch enough auxiliary airs, pot is peripheral to be extended to being heated to cause the gas high-temperature zone, and the efficiency of heating surface reduces; Limited by burner structure, circumferentially uniformly combustion gas from the burner ejection, the auxiliary air even with circumferential asymmetry contacts, owing to there being local location, gas flame mixes inhomogeneous with auxiliary air, cause the non-uniform combustion of combustion gas, be the harmful components such as carbon monoxide in the assurance flue gas, be lower than the product technology standard-required, can only strengthen total burning required air supply, so also can cause the gas-cooker Efficiency Decreasing.
This shows, further promote the interior fireworks kitchen range thermal efficiency, need to solve two problems: guarantee that there are enough SAS Secondary Air Supplies at the gas-cooker center, gas flame and auxiliary air even contact.
Summary of the invention
The objective of the invention is: a kind of gas kitchen ranges is provided, and it can supply auxiliary air effectively, guarantees that fuel gas buring is abundant, improves the thermal efficiency.
The present invention is achieved in that a kind of gas kitchen ranges, comprises liquid dish, burner, inner fire cover, outer fire cover and outer shroud distributor, and the hole of stretching out of burner is arranged on the central boss of described liquid dish; Described burner is by outer shroud mixed air cavity, interior distributor, interior induction tunnel and outer skirt is one-body molded makes, and the lamina tecti of described outer shroud mixed air cavity extends to interior distributor and is fixed together to radially inner side; Have that two tube connectors upper end is communicated with the outer shroud distributor, the lower end is communicated with the mixed air cavity of outer shroud at least, the outer shroud distributor between adjacent two tube connectors and outer shroud mix the gap formation secondary-air passage between the air cavity; The described top board that stretches out the central boss at hole place rides against on the circumferential edge of top board of the mixed air cavity of outer shroud; Described outer fire cover comprises internal ring wall, roof and external annulus, and its special character is: the interior fiery groove that a left side or dextrorotation are arranged on the internal ring wall of described outer fire cover; Described outer fire cover is annular from top view;
Or have on the internal ring wall of described outer fire cover on the interior fiery groove, external annulus of a left side or dextrorotation outer fire hole arranged, on the described outer fire cover in the area of fiery groove be the 30%-100% of outer fire hole area.
Described a kind of gas kitchen ranges, its special character is: at least 8 millimeters in the gap between the top board of the base plate of described outer shroud distributor and the central boss of liquid dish.。
Described a kind of gas kitchen ranges, its special character is: several air air slots left-handed or dextrorotation are arranged on the described internal ring wall plate, and described interior fiery groove left-handed or dextrorotation is arranged on the internal ring wall plate between adjacent two air air slots.
Described a kind of gas kitchen ranges, its special character is: several flow distribution plates left-handed or dextrorotation are arranged on the described internal ring wall plate inwall, and flow distribution plate is between the interior fiery groove of adjacent two left-handed or dextrorotation.
A kind of cooker burner of the present invention, owing to adopting such structure, auxiliary air enters the space between inner fire cover and the outer fire cover through the gap between outer shroud distributor and the burner, with the contacts fuel gas of internal flame fire hole ejection, realizes combustion process; Another part auxiliary air enters from the outer fire cover outside, with the unburnt combustion gas of internal flame fire hole, and the contacts fuel gas of the outside ejection of outer fire cover, finish completing combustion; The high-temperature flue gas that forms behind the fuel gas buring with convection current and heat radiation mode, is delivered to heating kettle with heat, realizes heat exchange, finishes heating process; Improved work efficiency.
