Abstract
The utility model relates to an oil-smoke exhauster which can remove the oil-smoke in kitchens, mainly solving the technical problems of a single-fan double-suction hole type oil-smoke exhauster. Gas flow can generate high speed airflow in a suction pipe through a blast pipe to cause the suction pipe to suck the oil-smoke by applying the fluidics principle. Because the single-fan double-suction hole structure is adopted. The electricity can be saved 40-60 % and the suction force can be obviously increased. The utility model is liked by a large quantity of consumers.
Description
The utility model relates to a kind of device that can get rid of oil smoke in the kitchen, especially the double lampblack absorber of being made up of casing, fan, control circuit.
In the prior art, producing ten thousand precious automatic cooking fume exhausters as Zhuhai is to adopt two fans to be contained in two respectively to inhale on the holes pump drainage oil smoke behind the rotary work, the smokejack of this fume exhausting fan is that horizontal direction adds a dividing plate and forms two smokejacks naturally in the co-operation volume of two fans, the oil smoke air-flow is made horizontal direction earlier and is flowed in smokejack, turn to 90 degree to get rid of the oil smoke air-flow by the air outlet of casing top thereafter.Because air-flow is in whole pump drainage process, suddenly through the turning to of 90 degree, make a lot of wind-force of loss, not only power consumption, mist extractor effect but also poor.Both made Nanjing produce bat board fume exhausting fan, though be single fan, this product has only one to inhale the hole.
The purpose of this utility model is only to play the effect of pump drainage oil smoke simultaneously of double suction hole with a fan.
Technical solution of the present utility model is achieved in that a kind of by casing, fan, in the smoke exhaust that control circuit is formed, draws a threeway shape suction tube on two suction holes with the casing lower end, and another pipe is the air outlet of complete machine.Fan is fixed on the interior bottom plate of casing, and the air-supply end shield of fan has a threeway shape blast pipe, and its other two discharge pipes insert respectively in two pipes of threeway shape suction tube.
Can adopt axial blast type or tangential direction blast type fan, when fan rotates, the air-flow air blast is blown in the suction tube by two blast pipes respectively, form powerful air-flow and discharge through air outlet, this moment, the casing inlet scoop produced negative pressure to suction tube, will discharge through air outlet in the oil smoke suction line.
Advantage of the present utility model is to have adopted single fan double suction hole pump drainage oil smoke mode, than original product economize on electricity 50%, because the threeway shape blast pipe that single fan double suction hole pump drainage oil smoke mode is determined, suction tube structure, air-flow in blast pipe after the air blast at a high speed directly in being blown into suction tube, forming powerful air-flow discharges through air outlet, inhale the hole and produce negative pressure this moment to suction tube, with discharging through air outlet in the oil smoke suction line, makes the pump drainage ability improve greatly.Could inhale moving napkin paper according to the former machine of test apart from inhaling 200mm place, hole, the smoke exhaust after the improvement just can inhaled a napkin paper apart from inhaling 300mm place, hole.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the internal structure schematic diagram of the smoke exhaust of second embodiment of the present utility model.
With reference to accompanying drawing 1, a kind of smoke exhaust is made up of casing 3, fan 2, control circuit, draw a threeway shape suction tube 4 on two suction holes with casing 3 lower ends, another pipe is the air outlet 5 of complete machine, the plastic injection-moulded one-tenth of threeway shape suction tube 4 usefulness " people " font, and its two suction tube portions have two holes respectively.Adopt axial blast type fan 2, be fixed on the casing 3 interior bottom plates, the air-supply end shield of fan 2 has a threeway shape blast pipe 1, its other two pipes insert respectively in two holes of threeway shape suction tube 4, threeway shape blast pipe 1 is with plastic injection-moulded one-tenth " ox horn " shape, and its two blast pipe air-out oral areas are with an attached suction tube 7 that helps respectively in suction tube 4.A turnover panel 6 is equipped with in its blast pipe 1 throat, be respectively equipped with three control positions with mechanical pull bar mode at casing 3 panel positions, block left adapter tube left when promptly turning over, work in the right hole of inhaling, stifled position right " ox horn " pipe when turning over to the right, hole work is inhaled on a left side, during the centre position, about inhale the hole and work simultaneously, after selecting the turnover panel position, open fan 2, the air-flow air blast is blown into by two " ox horn " shape blast pipes 1 respectively forms powerful air-flow in " people " font suction tube 4, inhale holes to " people " font suction tube 4 for two of casing 3 bottoms at this moment through air outlet 5 discharges, oil smoke is sucked " people " font suction tube 4 after air outlet 5 is discharged with the attached suction tube 7 interior negative pressure that produce that help.
With reference to Fig. 2, in another embodiment, adopt tangential direction blast type fan 2, its air-supply end shield has one " W " font blast pipe 1, two discharge pipes of blast pipe 1 insert respectively in " people " font suction tube 4 and are with two auxiliary suction duct 7 respectively at the air-out oral area of two blast pipes in suction tube 4, suction tube 4 is enclosed within respectively on two suction holes of casing 3, and its another pipe is complete machine air outlet 5.
