Description

Hood

The utility model relates to a kind of kitchen oily fume exhauster.

At present, all oil-containing air exhauster for kitchen, all be to place the cooking stove top, utilize its wheel rotation that the oil smoke that produces is drawn in the lampblack absorber, discharge outdoor through discharge duct again, this smoke exhaust has some shortcomings: at first, oil smoke is all outdoor through the blade and the inner discharge of smoke exhaust, use after a period of time, the housing of impeller and whole smoke exhaust all can be firmly greasy by oil smoke, as untimely cleaning, the rotation of impeller will be affected, and the cleaning smoke exhaust is the work that promptly bothers specialty, if installation is bad after cleaning, the smoke discharging effect of smoke exhaust is reduced; Secondly, smoke exhaust is placed on the top of cooking stove, if it is too near apart from cooking stove, operator's work can be hindered,, the efficient of getting rid of oil smoke can be reduced again if too far away apart from cooking stove, just present operating position, smoke exhaust generally places apart from kitchen range surfaces 800 millimeter, and at this moment can take oil smoke about 60-70% away with 70-90 watt power, and remaining oil smoke is still polluting all apparatus in the kitchen.

The purpose of this utility model is to improve the deficiency of prior art, and a kind of kitchen mist extractor is provided, and it is outdoor until discharging to utilize compressed air that the oil smoke that is produced is blown into exhaust uptake.

The purpose of this utility model is achieved in that this kitchen oily fume exhauster is by special type cooking pot, source of the gas, source of the gas passage and smoke discharging pipe are formed, special type cooking pot is made up of pot body and double wall, and the top edge of double wall exceeds the pot edge, and a flange is arranged in pot, open a hole on the wall of double wall, establish an adapter in the hole, connect source of the gas in the adapter, source of the gas can be pipeline compressed air or air pump etc., be provided with smoke discharging pipe above special type cooking pot, the outlet of smoke discharging pipe is stretched to outdoor.

When carrying out cooking process, connect source of the gas, compressed air enters double wall by the source of the gas passage by the interface of special type cooking pot double wall, discharges from the top edge of double wall.Because the flange in the oriented pot of double wall top edge, compressed air enters special type cooking pot, and the oil smoke that unexpected outburst is come out concentrates on a direction relatively and flows, and the pull out force of hot-air rising is discharged from the smoke discharging pipe that the special type cooking pot top is set in addition.

Because employed compressed air will contact with food in the pot,, and must filter with the oil-free lubrication air pump through strict so it must clean.

In smoke discharging pipe, meet condensation for fear of the oil smoke of atomizing and tie and fall in the special type cooking pot, establish a gathering room in the porch of discharge duct.

The outlet of smoke discharging pipe is stretched out outdoor, establishes the air outlet of a box haul in outdoor exit, so that at any wind direction mist extractor smoothly.

Can establish an air inlet switch in adapter place of special type cooking pot double wall, in order to the size of switch and adjusting compressed air air inflow.

Existing smoke exhaust is not only taken away cooking the oil smoke that is produced in the pot from the top suction oil smoke of cooking stove, simultaneously also a part can be siphoned away, the waste gas of cooking stove flame generation etc. can be effectively got rid of for the kitchen oily fume exhauster that the utility model is provided to stove fire waste gas after burning and not clean-burning material.At the outward flange of special type cooking pot and the outside flange of the outward flange system one of double wall on it, perforate or seam on the flanging at corresponding discharge duct air inlet place.Because the cooking stove EGT is higher, smoke discharging pipe has bigger suction force to it, so structure can be drained the waste gas that is produced by the cooking stove flame combustion effectively.

The kitchen oily fume exhauster that the utility model provides has been exempted the worry of dismounting cleaning fan of sucking oil fume, and the smoke exhaust efficiency height,

In conjunction with the embodiments the utility model is elaborated below by accompanying drawing

Embodiment 1: as shown in Figure 1, the outer exterior wall of special type cooking pot 1 has a double wall 2, welded together with special type cooking pot, the top edge of double wall exceeds the pot edge of special type cooking pot, and inwardly there is a flange 3 to play deep bead, the affixed conical pipe 4 of perforate is located in the bottom of a pan of leaning on of double wall, join with the air compressor machine blast pipe 6 that is fixed on nut on the kitchen range 5, on the air intake duct 8 of air compressor machine 7 grade one filter 9 is arranged, secondary filter 10 is arranged on blast pipe 6, on blast pipe 6, also establish a branch road 11 and link up, have on the branch road 11 on a valve 12 blast pipes switch 13 is arranged, in the time will regulating the air inflow of compressed air in the special type cooking pot double wall with air intake duct 8, coordinate valve 12 and switch 13, in case the air compressor machine fault, the adherent smoke discharging pipe that is provided with above special type cooking pot, it is by adapter sleeve 14, spacer shell 15 and smokejack 16 join and form, there is an inside flange bottom of adapter sleeve as gathering room, and flange tilts to the outside of special type cooking pot, is burnt so that the oil smoke in the gathering room flows to fire door.

Embodiment 2:

As shown in Figure 3, there is outside flange 17 of a week in the outer wall of special type cooking pot and the last double wall outside thereof, some hole 18(are arranged as shown in Figure 4 on the flange at corresponding smoke discharging pipe place), get rid of the waste gas that cooking stove flame produces thus, other structure is identical with embodiment 1.
