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 fume exhaust fan combined type suction 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 are formed; 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 a centrifugal impeller integral body and be installed in the spiral case inboard with motor; Motor rotation drives centrifugation blade and rotates; Oil smoke is inhaled in the middle of the impeller, and the certain orientation high-speed rotating impeller produces centrifugal force, under action of centrifugal force; The oil smoke that gets into the impeller inner ring is thrown out of the impeller outer ring, changes through the peculiar radial dimension in spiral case inner ring and centrifugation blade outer ring and realizes that oil smoke separates.
Above-mentioned receded disk impeller structure kitchen hood; Though the suction that also can realize oil smoke with separate; But in use for some time; It is long-pending attached to have a large amount of greasy dirts on the strip blade; The fume exhaust of lampblack absorber is renderd a service has certain decline; But also bring noise; At this moment need pull down lampblack absorber shell, spiral case and fan blade and clean the long-pending greasy dirt above the centrifugation blade that is attached to by hand; But unpick and wash extremely inconvenient; Accidentally can make the fan blade distortion; And the fan blade distortion can produce bigger noise; Receded disk impeller structure kitchen hood has also limited the further raising of fume exhaust ability simultaneously; Its main cause is that the strip blade can form a back-pressure air-flow towards first of the impeller suction side with the second length of a film strip blade outside that blows out, and therefore will promote very difficulty of present kitchen hood suction ability.
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 fume exhaust fan combined type suction impeller is provided.
Pull down the purpose of combined and instant for the suction impeller that realizes fume exhaust fan; Combined type suction impeller of the present invention; Remove the defective of receded disk impeller and spiral case combination ability lampblack suction exhausting, have only outer ring, oblique spiral fan blade, inner ring three parts to form, do not have 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 through motor shaft and impeller Internal and external cycle mounting screw, stack mounting becomes a top fuller body suction impeller.
Working principle of the present invention is such; It is inboard that inner ring is installed in motor shaft one end through the inner ring axis hole; Outer ring and consubstantiality are connected oblique spiral fan blade above the outer ring; Be installed in the motor shaft outside through 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 installed in 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; Oil smoke is attracted to the fan blade inboard; Because of fan blade is spiral oblique structure; Motor is pressed the certain orientation high speed rotating again; Therefore it is distinguished and admirable to produce huge spout, oil smoke sucking-off impeller, discharges the outside.This combined type suction impeller has also improved kitchen ventilator suction ability simultaneously.
As optimal design; When needs are pulled down the cleaning of combination fan blade; Unscrew motor shaft head impeller Internal and external cycle mounting screw; Just can pull down oblique spiral fan blade in impeller outer ring and impeller inner ring; Because of oblique spiral fan blade is connected with the outer ring consubstantiality; Cleaning finishes to reinstall and also can not make oblique spiral fan blade distortion; This oblique spiral fan blade and the combination of impeller outer ring consubstantiality, the inner ring outside can closely combine with oblique spiral fan blade inboard again, and the suction impeller that fuses is characteristics of the present invention places.
