Description

Efficient direct fuel injection kitchen range

The utility model relates to a kind of kitchen range, a kind of kitchen range of fuel oil especially are the kitchen range of fuel with diesel oil.

The kitchen in some restaurants, hotel etc. is except using gas range now, adopt the atomized diesel fuel kitchen range mostly, the structure of this atomized diesel fuel kitchen range mainly comprises stove, pot frame, burner, fuel tank, blower fan etc., wherein burner mostly is bowl structure, because it does not add the oil gas mixing arrangement, light preheating so must carry out naked light to fuel oil before using, carry out just carrying out normal combustion after the atomizing of fluid with pressure gas source again, therefore the operation of this atomized diesel fuel kitchen range is cumbersome, effect of combustion is bad, incomplete combustion, the thermal efficiency is low.

The purpose of this utility model is in order to overcome the deficiency of above-mentioned existence, and a kind of efficient direct fuel injection kitchen range that oil gas mixing unit carries out direct combustion that has is provided.

The purpose of this utility model is finished by following technical solution, oil range mainly is made up of stove, pot frame, burner, fuel tank, inflator etc., burner is arranged on a pot frame bottom, center, bottom at burner is mounted with oil-gas spraying and mixing apparatus, and band was led the fire guider in combustion hole in the middle of the top of burner was mounted with.

Burner design of the present utility model is the straight barrel shape of the rim of a bowl, is evenly equipped with the oxygenation hole on the burner perisporium near the spout of oil-gas spraying and mixing apparatus.

Described oil-gas spraying and mixing apparatus includes mixing chamber, gas source interface, fuel injection nozzle, and the gaseous mixture spout is arranged on the top of mixing chamber, and fuel injection nozzle and spout and lead the combustion hole on same round center line.

Description of drawings is as follows:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a contour structures schematic diagram of the present utility model.

Fig. 3 is a burner structure schematic diagram of the present utility model.

Below will the utility model is further introduced by accompanying drawing: a stove 1 is arranged, and it be provided with two pot framves 2, then also is provided with a slaughterhouse 3 in the middle of their.The bottom of every pot frame 2 all is mounted with a burner 8, and the top of this burner 8 is bowl-shape, and the bottom is straight tubular, and the bottom then is mounted with oil gas mixing directly spray device 17.In stove 1, also be mounted with inflator 15 and fuel tank 16.Oil gas mixing directly spray device 17 includes mixing chamber 13, there is a gas source interface 14 to link to each other with inflator 15 on the wall of mixing chamber 13 by air cock 4, also be mounted with the fuel injection nozzle 12 that is communicated in fuel tank 16 with oil pipe 19 in the mixing chamber 13, and this fuel injection nozzle 12 faces the gaseous mixture spout 11 that is arranged on mixing chamber 20 tops, and makes fuel injection nozzle 12 and gaseous mixture spout 11 and the combustion hole 18 of leading that is placed on the fire guider 9 on burner 8 tops be in the same center line.Described fire guider 9 is positioned at burner 8 the rim of a bowl ends, and its center offers leads combustion hole 18, then offers passage on the limit, is equipped with oxygenation hole 10 in the bottom of burner 8 near on the perisporium of gaseous mixture spout 11.The utility model also is provided with auto lighting switch device 7, and is mounted with total power switch 5 in the front of stove 1, firing switch 6.Be the tube structure, the utility model also can adopt manual firing's mode, directly ignites on fire guider 9 and lights.During use, open oil range power switch 5, inflator 15 work also produce Compressed Gas, open air cock 4 this moment, Compressed Gas enters mixing chamber and discharges at a high speed from mixing chamber spout 11 from gas source interface 14 through tracheae, make fuel injection nozzle 12 produce negative pressure, fuel from fuel tank 16 is sucked out, spray from fuel injection nozzle 12 through oil pipe 19, and under the effect of pressed gas, fully be gasificated as atomization gas and directly spray into into burner 8 from spout 12, meanwhile start automatic ignition device 4 fuel oil that has been atomized in the burner 8 and nebulize is lighted at once.The flame of spray combustion was scurried upwards burning rapidly from leading combustion hole 18, had not scurry the flame of leading the combustion hole on a small quantity and return to scurry from lead the combustion hole again and concentrate upwards burning.Because upwards the flame of spray combustion is not subjected to big stopping, thereby can reach the good effect of straight spray burning, increased the dynamics of burning, guaranteed the abundant burning of fuel oil, thereby the thermal efficiency is improved.

The utility model compared with prior art, have simple in structure, reliable, easy to use, Sufficient combustion, combustion heating efficient high.
