Abstract
The invention discloses an impeller combination type double-wind-wheel fan which comprises wind wheels and consists of an inner part and an outer part, wherein the inner part and the outer part have different shapes and structures. As an optimal design of the invention, a semi-part of each wind wheel is in a centrifugal type straight blade structure, an external semi-part of each wind wheel is in a spiral air suction type structure, and the wind wheels are installed in a spiral case with a special shape through a motor input shaft. According to the impeller combination type double-wind-wheel fan disclosed by the invention, with the wind wheel layout that the inner shape and structure are different from the outer shape and structure, the advantages of powerful air suction of spiral air suction and large air outlet of a centrifugal type straight blade are fully utilized, so that when the wind wheels are driven by a motor with low rotational speed, strong wind with certain pressure is blown out from an air outlet of the spiral case with the special shape; and the air outlet with a shape in the same structure is also installed at the other end of the motor, so that the purpose of the impeller combination type double-wind-wheel fan is achieved, the air outlet volume of the fan is large, the wind pressure is high, and the running is stable and silent.
Description
Technical field
The present invention relates to various blower fans, box-like pair of wind wheel blower fan of particularly a kind of impeller sets.
Background technique
Blower fan is the indispensable crucial combiner of industry equipment and household electric appliance, and at present known various blower fans have following several kinds: 1, scroll casing type centrifugal fan, 2, air pump, 3, helical runner do not have the shell-type blower.
1, the scroll casing type centrifugal fan is formed by spiral case and centrifugal type wind wheel motor combination; This scroll casing type centrifugal blower by the driven by motor centrifugal wind wheel rotate by certain orientation realize blowing, the purpose of air draught; But this scroll casing type centrifugal blower volume is big, and electrical consumption power is big.
2, though air pump blows, but the effective manufacturing process of air draught is accurate, manufacture cost is high, and noise is big, makes air pump be difficult to be applied in above the household electric appliance.
3, helical runner does not have the shell-type blower, though overcome above-mentioned scroll casing type centrifugal fan and there is technological deficiency in air pump, owing to will under high-revolving driven by motor, just can have high wind to blow out effect, makes to be applied in that noise is difficult to descend on the household electric appliance.
Summary of the invention
Technical problem to be solved by this invention for this reason is to overcome the defective that present scroll casing type centrifugal fan, air pump and helical runner do not have the technology of shell-type blower existence, aims to provide box-like pair of wind wheel blower fan of a kind of impeller sets.
The present invention also aims to provide a kind of single driven by motor blower fan that two groups of fan blades rotate.
In order to realize above-mentioned purpose; Box-like pair of wind wheel blower fan of impeller sets of the present invention comprises that wind wheel partly is made up of inside and outside difformity structure two, as optimal design of the present invention; Half part is centrifugal straight impeller structure in the wind wheel, and outer half part is a spirality air drafting type structure.
As further optimization of the present invention; Above-mentioned wind wheel is installed in through motor output shaft inside the spiral case of special shape, and the wind wheel layout of this inside and outside difformity structure makes full use of strong advantage of spirality air drafting type air draught and the big advantage of centrifugal straight leaf air-out; Make wind wheel under the not high drive of motor speed; The exhaust outlet of special shape spiral case has the high wind of certain pressure to blow out, and can install at the other end of motor with the shape of spline structure, reaches the goal of the invention of box-like pair of wind wheel blower fan of impeller sets of the present invention; Make that the blower fan air output is bigger, blast is higher, it is more steady, quiet to turn round.
Working principle of the present invention is such; Motor is installed in left and right sides special shape spiral case neutral position, and wind wheel is installed in special shape spiral case the inside, the left and right sides by the output shaft at motor two ends respectively through nut, and electrical power rotates a two ends wind wheel is rotated; Special construction because of left and right sides special shape spiral case; Wind wheel rotates and produces certain blast in the spiral case that makes the special shape special construction, and blast flows to exhaust outlet simultaneously in the special shape spiral case of the left and right sides, makes special shape spiral case exhaust outlet have high wind to blow out.

Embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, the technological scheme that the box-like pair of wind wheel blower fan of impeller sets of the present invention adopts comprises that wind wheel 1 partly is made up of inside and outside difformity structure two; As optimal design of the present invention; 1 li half part of wind wheel is centrifugal straight leaf 6, and outer half part is a spirality air drafting type fan blade 2, and wind wheel 1 is installed in spiral case 7 the insides of special shape through motor output shaft 4 usefulness nuts 3; The wind wheel layout of this inside and outside difformity structure; Make full use of the strong advantage of spirality air drafting type fan blade 2 air draughts, the big advantage of centrifugal straight leaf 6 air-out, make wind wheel under the not high drive of motor 5 rotating speeds, the exhaust outlet 8 of special shape spiral case has the high wind of certain pressure to blow out; And can install at the other end of motor 5 with the shape of spline structure, reach the goal of the invention of box-like pair of wind wheel blower fan of impeller sets of the present invention.
