Referring to the orawimgs and initially to Figs. I and 2, in âCCulda~ C with 20 the present invention a velltilator hood is provided for a cooker (not shown) located i~ . and comprises a body portion 10 including a frst side, a second side, a iirst end, a second end, and am underside. An inlet portion 20 ismounted on the underside oi` the body portion 10 for illlludu~ g an air/oil mixture created from the cooker to ]?ass i' ~,lh,UU~Il. A spraying portion 40 is mo~nted25 in the umderside of the body portion 10 for injecting water to condense the air/oil mixture introduced from th~ inlet portion 20. A separating portion 30 is locatedumder the spraying means 40 for separating the air/oil mixture delivered from the spraying portion 40 into oil and air. A storage portion 50 is disposed under the _ ~
21~49 separating portion 30 for r~ceiving the oil releæed therefrom amd the water released from the spraying l)ortion 40 via the separating portion 30. An outlet portion 60 is mounted on th~: underside of the body portion 10 near the first side thereof and in c~"",."~."~ ~.nn with the separating portion 30 for introducing the air supplied therefrom. Two motors 64 are mounted on tbe first side of the body portion lO, and two fans 65 e ach are ~ Jc~,Liv~ly actuated by tbe associated motor 64 for extracting the air de'livered through the outlet portion 60 to an exterior ~IIVil U~
The body portion 10 comprises an engagmg plate 16 vertically fitted to a o wall (not shown), a top plate 12 is formed on the first side of the body portion 10 and hnri7nntsl1y extends oultwardly from the engaging plate 16, a panel 14 is formed on the second side Or the body portion 10, a mediate cover 13 is hingedlyconnected between the top plate 12 and the panel 14, and two side plates 11 s~lb~ts~-ti~lly inverted L-shaped each respectively enclose t_e first and secondends of the body portion 10. The panel 14 includes an extension 142 formed on the underside of the body portion 10 arld extending toward the engaging plate 16, and a recess 22 is defined m the extension 142.
The inlet portion 20 comprises a heating plate 23 mounted on tbe umderside of the body portion 10 for heating the air/oil mixture i~ ud:u~,cd through the inlet portion 20. The heating plate 23 is preferably moumted on the extension 142 and is connected via a wire 152 to a control switch 15 which is mounted on the panel14 for controlling the heating plate 23. A concave channel 45 is defined in a distal end portion of the e~tension 142, and an over~low plate 450 is verticallyformed on the distal end portion of the extension 142.
2s T_e separating porti~)n 30 comprises a plurality of first guiding plates 33formed together each .~.b. 'ly V-shaped in section and a plurality of second guiding plates 34 formed together each s~bstsnti~1ly V-shaped in section. A

s A first l' .' v 32 is vertically formed on the underside of the body portion 10 near the first side thereof arld extends downwardly to abut against the plurality of frst guiding plates 33. A draining duct 62 is vertically defined between the engagiing plate 16 and the fist diaphragm 32. An arcuate introducingplate 61 is formed on a lower portion of the engaging plate 16 and extends o beneath a boti~om portion of the frst guiding plates 33, thereby defining a slit 610 t~ which c~ with the draining duct 62. A second diaphragm 31 which is heat- isolating abuts against the plurality of second guiding plates 34.
A bafi~e 36 is vertically formed on a lowermost portion of the second IS guiding plates 34 and extellds downwardly therefrom, thereby deflning a frst passage 54 located betweeil the second diaphragin 31 and the bai~le 36 for receiving the water i~owing through the tortuous conduit 35, and a second passage 51 located between the engaging plate 16 and the baffle 36 for receiving the oilflowing through the tortuous conduit 35. A gap 55 is defined in an underside of the bafiile 36 and c~ .t~.~ between the frst and second passages 54 and 51.
In practice, water is i~ the first passage 51 at a level lower than that of the oil due to a difference in dellsity ~ b~ ,.,n, therefore, the water will flow and c.- bet~veen the first and second passages 54 and 51 freely via the gap 55, while the oil is retained in the second passage 51 and is prevented from 2s entering into the first passage 54 by means of the baf~le 36. An elongated oil draining tube 52 is verticall.y mounted in the second passage 51 and includes a truncated upper end 520 fo] u~u~il,v the overfi'ow o~ u~h when the oil retaiined in the second passage 51 is at a level higher than that of the truncated upper end 520, and a lower end for draining the overflow oil to outside, and a valve 522 is mounted arountl the lower end of the oil draining tube 52. A short draining tube 53 is moumted :in the second passage 51 for d;JcLal~ulg the water or deposition of impurities to outside, and a valve 530 is moumted around the shorts draining tube 53 for controlling a flow amount through the short draining tube 53.
Again referring to Figs. I and 2 with reference to Fig. 3, the spraying portion 40 comprises am elorlgated pipe 44 h~ri7~ntP11y mounted in the concave channel 45 with two distal erlds thereof each fixedly attached to the COllt:~ùudu.
side plate 11. A plurality of nozzles 440 laterally are defined through the elongated pipe 44 for pouling water ~ uugh. A ~ .r~ g tube 41 is vertically mounted on one clf the two side plates 11 near the second end of the body portion 10 and irlclude~; a lower end c~ ~ with the first passage 54 of the storage portion 50 an~l an upper end C~ .. ;r ~; .g with one distal end of the elongated pipe 44, a pump 42 is mounted around the c~ ;. E tube 41 for actuating the water received in the first passage 54 to move upwardly into the pipe of the spraying portion 40.
Preferably, a source Itube 441 is comnected to the side plate 11 under the ~ tube 41 amd - with- the first passage 51 of the storage portion 50 for supplying wa~ter into the first passage 54 via the second passage 51 SO as to retain a level of water in the first passage 54 to a proper position, and a valve 442 is mounted on th~ source tube 441 for controlling am amount of water flowing through the source tube 441. ~n addition, a LI~lJ~ Lt window 310 is mounted on a lower portion of the second ~ rhlP~n 31 for viewing and inspecting the level of water in the first passage 54.
2s In operation, the air/oil mixture from the cooker is i~ uduc~ through the recess 22 into the inlet operling 24 and is heated by the heating plate 23 so as to be retained in a state of high t~,~lp~ UI~;, thereby preventing oil from being c~m~lPncpd from the air/oil mixture. Water is injected into the concave channel 45 . .

When tlhe level of water is higher than that of the overflowplate 450, water will flow tlhrough a chute 452 defirLed between the distal end portion of the extension 142 and the top portion of the first guiding plate 33 and is s sl-L-~l ~y irl contact wit~L the air/oil mixture with hLgh ~ Cla~UI~ SO as to condense and extract oil from the air/oil mixture such that oil is taken away by the water to flOw downwardly tbrough the tortuous conduit 35 into the second passage 51.
The air separated froln the air/oil mixture is introduced into the draining duct 62 via the slit 610 and the arcuate illtludu~ plate 61 by means of the farls 65 each actuated by the associated motor 64, ~ c.~ ly passes through a chamber 63 defined irl the ullderside of the top plate 12, and is finally drained to outside from two outlet ports 120 which are defined through the top plate 12.
Preferably, two meshes 121 l~ach are respectively fitted in a C.Jlll,;~JUlldUlg one of the two outlet ports 120 for filtering the air passing ~ lU;~hoU~ Each of the two motors 64 is mounted on a bracket 640 which is securely mounted on the top plate12 above the associated outlet port 120.
It is to be noted that, the fans 65 are l~a~lJc~ ly actuated by the motors 64 to draw the air received in ~he chamber 63, in the draining duct 62, and in the 20 tortuous conduit 35 to D~ ' ,,, t~Lereby forrning a negative pressure status therein such that the air/oil nlixture Ieleased from the cooker is easily drâwn into the tortuous conduit 35 through the inlet opening 24 and the recess 22 of the inlet portion 20. Then the oil is removed from the air/oil mixture by mearls of tlLe spraying portion 40 cooL ~, ~ with the tortuous conduit 35 to be conveyed into 25 and contained in the second ]~assage 51 of the storage portLon 50, and the released air is acc~' ' into the draining duct 62 via the slit 610 and is drawn to DUllU ~o~ via t~Le chambel 63.
Referring to Fig. 4, in accu dau~c wit~L another . b~ l of the present ` 214~5~9 invention, the top plate 12 together with the motors 64 and fans 65 are arranged in a tilted manner.
