Abstract
The utility model relates to a cooking fume exhausting device convenient to clean, comprising an exhaust fan 1, a gas skirt 2, an exhaust gas pipe 3, a fastigiate pressure supporting generation pipe 4, and a three-way 5. The exhaust fan 1 is arranged on the outside of the gas skirt 2; the big diameter end of the pressure supporting generation pipe 4 is connected with the air passage exit of the exhaust fan; the small diameter end of the pressure supporting generation pipe 4 is inserted in the three-way 5 and extends to the exhaust gas pipe 3 which inserts the three-way 5 from the face; the three-way 5 covers the neck of the gas skirt 2 through the third hole itself which is plumb with the axles of two holes before. The cooking fume exhausting device convenient to clean uses the exhaust fan and the fastigiate pressure supporting generation pipe to produce negative pressure so as to make the oil smoke collected by the gas skirt excrete to the exhaust gas pipe without passing fan blades. The utility model has the advantage of easy to clean, and is suitable for eliminating and collecting oil smoke.
Description
The utility model relates to a kind of improved smoke exhaust, belongs to collect or remove dirt flue dust field.
Existing smoke exhaust mainly is made up of parts such as exhaust fan, gas skirt and offgas duct, and ventilating fan is located in the current collection cover, and the oil smoke flabellum of flowing through is discharged into offgas duct during work.Its shortcoming is that the exhaust fan blade directly contacts with oil smoke, very easily is infected with greasy dirt, causes and cleans difficulty.
Task of the present utility model provides a kind of oil smoke flabellum of not flowing through that makes, because of not staining the oily fume exhauster that ventilating fan is convenient to clean.
Task of the present utility model is finished like this: a kind of oily fume exhauster of being convenient to clean is made up of exhaust fan, gas skirt, offgas duct, this device comprises that also the taper negative pressure produces pipe and threeway, exhaust fan is contained in the outside of gas skirt, and by the stent support that is connected on the cover, the bigger diameter end that negative pressure produces pipe is connected with the ducting outlet of exhaust fan, miner diameter end inserts in the threeway, and puts in from right opposite and insert in the offgas duct of this threeway, and threeway is connected with the neck of gas skirt by self the 3rd hole.
Below in conjunction with accompanying drawing the utility model is elaborated
Fig. 1 is the utility model profile sketch map
Fig. 2 is the utility model longitudinal sectional drawing
Oily fume exhauster shown in the figure produces pipe 4 by centrifugal exhausting fan 1, gas skirt 2, offgas duct 3, taper negative pressure and threeway 5 is formed, exhaust fan 1 is contained in the outside of gas skirt 2, and by support 6 supports that are connected on the cover, the bigger diameter end that negative pressure produces pipe 4 is connected with the ducting outlet of exhaust fan, miner diameter end inserts in the threeway 5, and put in from right opposite and insert in the offgas duct 3 of this threeway, threeway 5 is by the neck of vertical with preceding two axially bored lines self the 3rd borehole jack at gas skirt 2.Exhaust fan 1 also can be a tube-axial fan.
During the utility model work, pure qi (oxygen) sucks from the air inlet of exhaust fan 1, press to negative pressure by the air channel and produce pipe 4, because this pipe is along airflow direction, its cross-sectional area dwindles gradually, cause the air velocity that flows through therebetween to increase and the pressure reduction, this variation reaches the most very at the miner diameter end that negative pressure produces pipe, thereby forms the negative pressure that is lower than ambient pressure, and this negative pressure sucks the mist of oil flue gas in the gas skirt, after the pure qi (oxygen) that flows through in the negative pressure generation pipe mixes, discharge to offgas duct 3.
By above narration as can be known, fan leaf of the present utility model does not contact with oil smoke, so be difficult for staining, what tarnish only is the offgas duct of cleaning easily.
Claims (2)
1, a kind of oily fume exhauster of being convenient to clean is by exhaust fan (1), gas skirt (2), offgas duct (3) is formed, it is characterized in that this device comprises that also the taper negative pressure produces pipe (4) and threeway (5), exhaust fan (1) is contained in the outside of gas skirt (2), and by support (6) support that is connected on the cover, the ducting outlet of exhaust fan is connected with the bigger diameter end that negative pressure produces pipe (4), the miner diameter end that negative pressure produces pipe inserts in the threeway (5), and put in from right opposite and insert in the offgas duct (3) of this threeway, threeway (5) is connected with the neck of gas skirt (2) by self the 3rd hole.
2, the oily fume exhauster of being convenient to clean according to claim 1 is characterized in that said exhaust fan (1) can be that axial-flow type also can be centrifugal fan.
