Description

A kind of single motor smoke exhaust ventilator

Technical field

The utility model relates to the kitchen utensils in a kind of family and restaurant, is a kind of oil smoke that produces during with the kitchen cooking, discharges single motor smoke exhaust ventilator in kitchen.

Background technology

Now, the kitchen smoke exhaust ventilator kind of selling on the market is a lot, and what the overwhelming majority adopted is bi-motor, bilobed wheel smoke exhaust ventilator.These products are made up of housing, bi-motor, bilobed wheel and smoke pipe, and motor and impeller are fixed in the smoke exhaust ventilator housing.These smoke exhaust ventilators are handsome in appearance, and most of oil smoke that the kitchen cooking can be produced be discharged to outdoor, has solved removing kitchen fume problem, make the kitchen operation personnel reduce oil smoke and poison.Because existing smoke exhaust ventilator bottom lacks darker petticoat pipe, the oil smoke that produces during cooking rises to housing bottom and is obstructed, and major part is discharged by impeller, and still some oil smoke is back to indoor from housing bottom.Secondly, owing to adopt bi-motor, bilobed wheel, the oil smoke that produces the negative pressure suction by impeller merges together, and discharges from smoke pipe then.Smoke pipe diameter float cigarette resistance strengthens, and has reduced smoke discharging effect.The 3rd, the greasy dirt on the impeller is thrown in the smoke exhaust ventilator housing under action of centrifugal force.The housing intracavity space is big and complicated, and greasy dirt is difficult to concentrate and discharges; The work of cleaning greasy dirt is difficult especially.

The utility model content

The purpose of this utility model provides a kind of single motor smoke exhaust ventilator, reduces smoke pipe smoke evacuation resistance and improves the mist extractor effect; Make greasy dirt be convenient to concentrate, flow out and make things convenient for cleaning.Overcome existing bi-motor, the big problem of bilobed wheel smoke exhaust ventilator smoke evacuation resistance, improve smoke discharging effect; It is big and complicated to overcome existing smoke exhaust ventilator housing, the difficult problem of concentrating, flowing out of greasy dirt and clean shortcoming such as greasy dirt difficulty.

The utility model is to realize like this; Single motor smoke exhaust ventilator is made up of motor, flabellum and smoke pipe, and motor is fixed on the support, it is characterized in that: smoke pipe is a reducing bend, and the two ends bore is small one and large one, and a big mouthful diameter is the 250-550 millimeter, and the osculum diameter is the 150-320 millimeter.Smoke pipe holds the elbow shape, and the smoke pipe diameter is for progressively excessive from big to small.In the smoke pipe big opening end, be fixed with electric machine support, fixed form can be that screw is fixed, and also can be that rivet connects or welding.Be fixed with motor and flabellum on the support.At different kitchen exhaust requirements, 3-6 sheet blade is arranged on the flabellum.Big mouthful of difference in internal diameters of flabellum external diameter and smoke pipe is the 5-30 millimeter.There is food tray big mouthful of below of smoke pipe.It is suitable for reading that food tray is inserted in smoke pipe Da Kou lower end.Big mouthful of external diameter of food tray upper-end inner diameter and smoke pipe is consistent.Owing to be to insert to cooperate, can rotate mutually between food tray and the smoke pipe.Oil guiding hole and lubricating cup are arranged at the food tray bottom.The food tray lower central is fixed with petticoat pipe.Fixed form is welding or button limit.The shape of petticoat pipe adopts hemispherical dome shape, and the top diameter of a circle is the 200-395 millimeter; The bottom is a rectangle, and rectangular length is the 700-3000 millimeter, and width is the 400-1500 millimeter.The petticoat pipe height is the 150-500 millimeter.Smoke pipe osculum end is plugged with a chimney cowl.Cap is conical, pole attachment cap and circular boop, and connected mode is riveted joint or welding.Circular boop inserts in the smoke pipe osculum.

Indoor in order to prevent mosquito to fly into by smoke pipe, on the circular boop mosquito-proof gauze can be arranged.

In order to reduce chimney cowl, a reverse cap is arranged in cap to discharging the resistance of oil smoke.Oppositely cap is conical and the cap welding, also can rivet.

Winter, outdoor air was cold, passed through in the smoke pipe inlet chamber for preventing outdoor cold air, and lid can keep out the wind at circular hole place, petticoat pipe sky.Keep out the wind the lid diameter with the sky Circularhole diameter identical.The lid that will keep out the wind from the petticoat pipe below inserts petticoat pipe top circular hole, and circular hole is built.Keep out the wind and cover jug.

The utlity model has good practicability, smoke discharging effect simple in structure is good.The oil smoke that cooking produces rises in the petticoat pipe, has little time diffusion, and just the strong negative pressure that is produced by the flabellum rotation sucks and discharges outdoor.Motor and impeller are directly installed in the smoke pipe, and impeller rotation makes and produces negative pressure in the petticoat pipe, and oil smoke is inhaled into smoke pipe and directly is discharged to outdoorly, reduces oil smoke time of staying in smoke exhaust ventilator, has reduced the smoke evacuation resistance.The flabellum rotation produces centrifugal force, and greasy dirt is thrown on the smoke pipe inwall, and oil smoke flows in the food tray under the gravity effect and compiles, by the oil guiding hole inflow lubricating cup of food tray.The food tray area is little, and be convenient to greasy dirt and concentrate, flow out, and the convenient greasy dirt that cleans.
