The fan is only used for providing air power source of the high speed flowing gas, isolating layers made of non-condensing materials are added to a gas collecting cover, a jet pipe, an exhaust pipe, and a wind preventing door of a non oil condensation entrainment type kitchen ventilator, and the oil condensation on the components is reduced. The utility model has the advantages of cleanness, and sanitation, and reduces the oil pollution and washing times.

Description

Non condensation of oil entraining type smoke exhaust

The utility model relates to a kind of non condensation of oil entraining type smoke exhaust of family kitchen pump drainage oil smoke.

At present, by family's widely used kitchen smoke exhaust ventilator, all be discharged from the outdoor process because of oil smoke, at the gas skirt through smoke exhaust ventilator, safety guard net, blower fan and blade, exhaust duct during storm door, condenses into fluid, the blade of blower fan particularly, being to promote the critical piece that oil smoke gas effluxes, and being in when work and running up, is again the only way which must be passed of oil smoke gas, the route that it moves in oil smoke gas is long, is to produce the maximum parts of condensation of oil.These fluid that congeal into adhere to or are thrown to casing by blade, form a large amount of oil droplets or greasy filth and pollute, and make the user keep its cleaning, need often carry out frequent scouring.Because of greasy filth does not resemble easy removing the dust, particularly heavy collection more difficult in blower fan brought many worries to the user, caused pollution for the kitchen environment of cleaning, influenced the use interest of people to it.

The purpose of this utility model provides a kind of smoke exhaust, oil smoke is being discharged in the process in kitchen, does not produce condensation of oil on the blower fan of smoke exhaust.

For achieving the above object, non condensation of oil entraining type smoke exhaust, fan blade is withdrawn from oil smoke gas discharge course, make oil smoke gas in discharging outdoor process, no longer pass through safety guard net and fan blade, make the critical piece of original generation condensation of oil, no longer contact with oil smoke gas, thereby making them no longer include condensation of oil produces, simultaneously on the remainder gas skirt of oil smoke gas process, exhaust duct, the storm door, increase the grease proofing airsetting knot of one deck material, make oil smoke gas when flowing through these parts, seldom produce and condense.

The design has at first changed the way that present oil pumper is directly used blower fan pump drainage oil smoke gas, and has adopted the jet entrainment principle of science, with the Air Entrainment power of quick air-flow injection generation oil smoke gas is entrainmented to be discharged into the exterior space.Enter the soot gas of gas skirt during use, be concentrated in around the jet pipe, the quick flowing gas that comes out from jet pipe, owing to be subjected to the restriction that the jet pipe outlet reduces suddenly, increased flowing velocity more, become jet-like, thereby around the jet mouth of pipe, formed negative pressure from the outlet ejection, to be in inlet scoop oil smoke gas all around, inspiration exhaust duct dual disposal is to outdoor.In non condensation of oil entraining type smoke exhaust, blower fan is only as providing quick flowing gas source to use, and with air inlet, be arranged on relatively in the outside, kitchen or indoor other room away from oil smoke gas, preventing oil smoke aspiration air intake machine, as be located at other room, also can promote room air changes, air inlet and blower fan are used with the diameter seal for pipe joints and are linked, thereby the blade of blower fan is not met with the oil smoke gas phase, have guaranteed no longer to produce on the fan blade condensation of oil.On the gas skirt of non condensation of oil entraining type smoke exhaust, jet pipe, exhaust duct, storm door, be liner in addition,, reach the effect that makes these positions seldom produce condensation of oil oil smoke gas and the isolation of above-mentioned parts with the anti-material white board that condenses.Liner is fixed with mode and housing that linear slit is solid by being located at around the housing bead and the aperture of turning point.Owing to adopted such scheme, no longer produce condensation of oil on the blower fan of non condensation of oil entraining type smoke exhaust and the blade, other position also seldom produces condenses.

Below in conjunction with Figure of description and embodiment the utility model is further specified.

Fig. 1 is the side air draft type schematic diagram of utility model.

Fig. 2 is a fixedly schematic diagram of liner and shell.

Fig. 3 is a top air draft type schematic diagram of the present utility model.

Among the figure 1, fan blade, 2, air inlet, 3, jet pipe, 4, gas skirt, 5, air entry, 6, exhaust duct, 7, storm door, 8, the anti-liner that condenses, 9, flowing gas fast, 10, oil smoke gas, 11, the secure liner line, 12, gas-flow deflector.

In embodiment illustrated in fig. 1, exhaust duct (6) is located at the side of gas skirt (4), air inlet (2) is located at the outside, kitchen away from lampblack absorber exhaust outlet place or indoor other room, use with the diameter seal for pipe joints between air inlet (2) and the blower fan and link, in case oil smoke gas (10) enters blower fan, fan blade (1) is located at the top of gas skirt (4) with the blower fan integral sealing, it is same central axis that jet pipe (3) should keep with exhaust duct (6), the quick flowing gas (9) that promotes to form through fan blade (1) pressurization become jet-like from jet pipe (3) mouth of pipe to exhaust duct (6) central-injection, the power of entrainmenting of Chan Shenging sucks exhaust duct (6) with the oil smoke gas (10) in the gas skirt (4) from air entry (5) and mixes and arrange to the outside air of kitchen therefrom.Exhaust duct (6) is short more good more, prevents that to reduce the time of oil smoke gas (10) in pipe the heavy collection of fluid is in pipe.On gas skirt (4), jet pipe (3), exhaust duct (6), storm door (7), be provided with the anti-liner made from white board that condenses (8), by being located at around the housing bead and housing turning point mode shown in Figure 2, consolidate on shell with secure liner line (11) seam.

That shown in Figure 3 is another embodiment that exhaust duct (6) is located at gas skirt (4) top, it is same central axis that jet pipe (3) still keeps with exhaust duct (6) and exhaust duct, and set up gas-flow deflector (12) in jet pipe (3) knee, through pipe bending point the time, do not depart from jet pipe (3) central axis to keep air-flow.

Claims (3)

1, a kind of non condensation of oil entraining type smoke exhaust, gas skirt is arranged, fan blade, exhaust duct, storm door, it is characterized in that: adopt the jet entrainment principle, be located at the quick flowing gas of gas skirt top blower fan with sealing means, the Air Entrainment strength that produces when the exhaust duct central-injection from the jet mouth of pipe, entrainmenting into from air entry oil smoke gas in the gas skirt, exhaust duct is disposed to the exterior space, air inlet is located at the outside, kitchen away from lampblack absorber exhaust outlet place, use between air inlet and the blower fan with the diameter seal for pipe joints and link, at gas skirt, jet pipe, exhaust duct, on the storm door, be provided with the anti-liner of making of white board that condenses, by being located at around the housing bead and the turning point aperture, fix with mode and housing that linear slit is solid.
