Description

Cabinet type jet exhauster for removing cooking fumes

The utility model is a kind of cabinet type jet smoke exhaust ventilator.

At present, the smoke exhaust ventilator of all kinds of models of selling on the market, its working method is oil smoke and directly enters atmosphere by fan blade through smoke exhaust pipe, and its shortcoming is to have deposited a thick layer of grease on blade and motor, gel grease, extremely difficult the cleaning is if untimely removing not only makes exhaust air rate descend, leaf weight also increases thereupon, causes motor load to strengthen; In addition, motor itself is under the working environment of high-temperature flue gas, and the grease deposition causes the radiating condition of motor more abominable in addition, so user's motor is happened occasionally by the burning accident, has influenced the service life of smoke exhaust ventilator; Moreover above-mentioned smoke exhaust ventilator influences the smoke pumping effect because of extraneous wind direction changes, and easily exterior wall is made dirty from the oil smoke that smoke exhaust pipe is discharged, and influences attractive in appearance.

The purpose of this utility model provides that a kind of smoke pumping is effective, and blower fan does not directly contact with oil smoke, discharges fume not that wind-engaging can all reclaim the oil of condensation to influence, does not pollute exterior wall, but and the cabinet type jet smoke exhaust ventilator of energy efficient.

The technical solution of the utility model is: make source of the gas with blower fan, utilize fluidics and air curtain all to bring the waste heat that the oil smoke that produces in the pot and kitchen range distribute into smoke exhaust pipe, overall structure is taked cabinet style, in the top of cabinet, be fixed with the taper exhaust fume collecting hood, the awl tip of exhaust fume collecting hood is connected with smoke exhaust pipe by the anemostat that is fixed on the frame top board, the other end of exhaust fume collecting hood covers on the kitchen range, have the petticoat pipe oil trap on this end margin, be fixed with the oil-collecting kettle on the oil trap and communicate, can make the greasy dirt on the exhaust fume collecting hood flow to the oil-collecting kettle by oil trap with groove; In the front lower place of kitchen range the air curtain airduct is installed, an exhaust curtain nozzle is housed on the airduct; The fan outlet place is provided with the airduct threeway, and an air port connects the air curtain airduct, and another air port connects the jet nozzle by the jet airduct, and the jet nozzle is fixed on the throat of the junction of exhaust fume collecting hood and anemostat; Smoke pipe is housed on smoke exhaust pipe connects oil can, be fixed with hurricane globe on the smoke exhaust pipe port of export.

Have oil trap on the hurricane globe edge of opening on the above-mentioned smoke exhaust pipe port of export, be fixed with oil return pipe between oil trap and the smoke exhaust pipe.

Above-mentioned cabinet makes monoblock type, and blower fan can be fixed in the cabinet of cabinet bottom, as makes separate type, and blower fan is fixed on the upper left corner of cabinet.

The top of above-mentioned cabinet has the cool breeze mouth.

The utility model so blower fan does not directly contact with oil smoke, has therefore improved the condition of work of blower fan owing to adopted fluidics and air curtain that oil smoke and waste heat are taken away; Hurricane globe is set, make discharge fume wind-engaging not to influence, also avoided exterior wall not dyed simultaneously by greasy dirt; Adopt cabinet type structure, make the oil smoke restriction within the specific limits,, show, descend 35% with general smoke exhaust ventilator specific energy consumption according to test result so smoke pumping is effective; In addition, adopt cabinet type structure, can make concentrated placements such as tableware, make the kitchen become clean and tidy, attractive in appearance, comfortable.

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

Fig. 2 is that Figure 1A-A is to cut-away view.

Be that the utility model is described in further detail for embodiment below with the accompanying drawing:

The utility model is taked cabinet type structure, cabinet is made up of the two revolving doors 25 of two revolving doors 24 in top board 1, side panel 2, front panel 3 and middle part and bottom, in the top of cabinet, be fixed with taper exhaust fume collecting hood 10, the awl tip of exhaust fume collecting hood 10 is connected with smoke exhaust pipe 14 by the anemostat 12 that is fixed on the cabinet top board 1, the other end of exhaust fume collecting hood 10 covers on the kitchen range 29, have petticoat pipe oil trap 17 on the edge of the exhaust fume collecting hood 10 of this end, be fixed with the oil-collecting kettle 16 that communicates with it on the oil trap 17; Illuminating lamp 18 and
