Abstract
The invention discloses a ventilator combined draft impeller which overcomes the defect that lamblack can be removed by combining a centrifugal impeller and a volute. The ventilator combined draft impeller comprises an outer ring, an incline helical blade and an inner ring without comprising a volute, wherein the outer ring and the incline helical blade are jointly connected with a shaft hole, the fan is of an incline strip-shaped helical special structure, the inner ring and an inner ring shaft hole are jointly connected, the outer side of the inner ring can be tightly matched with the inner side of the blade of the incline helical blade through a motor shaft and an impeller inner ring installing bolt and an impeller outer ring installing bolt to combine and install a round hammer induced drift impeller.
Description
Technical field;
The present invention relates to various family expenses fume exhaust fan suction impeller, particularly a kind of ventilator combined induced draft impeller.
Background technique;
known various family expenses fume exhaust fans are pressed the blower fan type at present, suction impeller adopts the centrifugal fan wheel mostly, centrifugal fan wheel construction fume exhaust fan comprises motor, spiral case, receded disk impeller, receded disk impeller has main circle, some long strip blades and positioning ring form, main circle center hole is connected with motor shaft, long strip blade one end is connected with main circle outer ring, the other end is connected with positioning ring, the long strip blade has several angle to install, form centrifugal impeller whole and be arranged on the spiral case inboard with motor, motor rotation drives centrifugation blade and rotates, oil smoke is inhaled in the middle of impeller, the certain orientation high-speed rotating impeller produces centrifugal force, under the effect of centrifugal force, the oil smoke that enters the impeller inner ring is thrown out of the impeller outer ring, change with the peculiar radial dimension in centrifugation blade outer ring by the spiral case inner ring and realize that oil smoke separates.
above-mentioned centrifugal impeller structure fume exhaust fan, although the suction that also can realize oil smoke with separate, but in use for some time, have a large amount of greasy dirts on the long strip blade long-pending attached, the lampblack suction exhausting effect of kitchen ventilator has certain decline, but also bring noise, at this moment need to pull down casing of kitchen ventilator, spiral case and fan blade clean the long-pending greasy dirt that is attached to above centrifugation blade by hand, but unpick and wash extremely inconvenient, accidentally can make the fan blade distortion, and the fan blade distortion can produce larger noise, the centrifugal impeller structure fume exhaust fan has also limited the further raising of lampblack suction exhausting ability simultaneously, its main cause is that the long strip blade is towards the first and the back-pressure air-flow of the second length of a film strip blade outside meeting formation that blows out of impeller suction side, therefore to promote present fume exhaust fan suction ability very difficult.
Summary of the invention
Technical problem to be solved by this invention is to overcome the defective that there is technology in present centrifugal impeller worm frame, and a kind of ventilator combined induced draft impeller is provided.
Pull down the purpose of combined and instant for the suction impeller that realizes fume exhaust fan, combined air suction impeller of the present invention, remove the defective of receded disk impeller and spiral case combination ability lampblack suction exhausting, only have outer ring, oblique spiral fan blade, inner ring three parts to form, there is no spiral case.The oblique spiral fan blade in outer ring is connected with the axis hole consubstantiality, fan blade becomes the screw type special construction of oblique strip shaped, inner ring is connected with inner ring axis hole consubstantiality, the inner ring outside can be inboard with the oblique spiral leaf blade in outer ring, closely cooperate by motor shaft and impeller Internal and external cycle mounting screw, combination is mounted to a top fuller body suction impeller.
working principle of the present invention is such, it is inboard that inner ring is arranged on motor shaft one end by the inner ring axis hole, outer ring and consubstantiality are connected to oblique spiral fan blade above the outer ring, be arranged on the motor shaft outside by the outer ring axis hole, motor shaft head is passed through in oblique spiral fan blade inboard, impeller Internal and external cycle mounting screw is closely connected into an impeller integral body with inner peripheral surface, when motor is pressed the certain orientation high speed rotating, also drive simultaneously and be arranged on motor one end fan blade inner ring, the fan blade outer ring is connected oblique spiral fan blade high speed rotating with the outer ring consubstantiality, at this moment the front end of oblique spiral fan blade produces huge cutting force, attract oil smoke fan blade inboard, because fan blade is spiral oblique structure, motor is pressed again the certain orientation high speed rotating, therefore produce huge spout distinguished and admirable, oil smoke sucking-off impeller, discharge the outside.This combined air suction impeller has also improved kitchen ventilator suction ability simultaneously.
As optimal design; When needs are pulled down the combination cleaning blade, unscrew motor shaft head impeller Internal and external cycle mounting screw, just can pull down the oblique spiral fan blade in impeller outer ring and impeller inner ring, because oblique spiral fan blade is connected with the outer ring consubstantiality, clean complete reinstalling and also can not make oblique spiral fan blade distortion, this oblique spiral fan blade and impeller outer ring consubstantiality combination can closely combine with oblique spiral fan blade inboard again outside inner ring, and the suction impeller that is connected is characteristics of the present invention places.
