Abstract
The utility model relates to an impeller combined type double-wind-wheel draught fan which is characterized in that a wind wheel is composed of two parts including an inner structure and an outer structure, the inner structure and the outer structure are different in shapes, the inner half part of the wind wheel is of a centrifugal type straight vane structure, the outer half part of the wind wheel is of a spiral air suction type structure, and the wind wheel is installed inside a volute in a special shape through an output shaft of a motor. The overall arrangement of the wind wheel with the inner structure and the outer structure in the different shapes fully takes advantages that the spiral air suction type structure is strong in air suction and the centrifugal type straight vane structure is big in air outlet volume, so that the wind wheel is driven under a low revolving speed of the motor, an air outlet of the volute in the special shape has strong wind to blow out, the strong wind has certain pressure, and at the same time, another wind wheel with the same structure can be installed at the other end of the motor, so that the purpose of the impeller combined type double-wind-wheel draught fan is achieved. The air outlet volume of the draught fan is large, the wind pressure is high, and operation is stable and silent.
Description
Technical field
The utility model relates to various blower fans, particularly box-like pair of wind wheel fan of 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: 1, scroll casing type centrifugal fan, 2, air pump, 3, helical runner is without 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 by certain orientation rotate to realize to blow, the purpose of air draught, but this scroll casing type centrifugal blower volume is large, and electrical consumption power is large.
2, although air pump blows, but the effective manufacturing process of air draught is accurate, manufacture cost is high, and noise is large, makes air pump be difficult to be applied in above household electric appliance.
3, helical runner is without the shell-type blower, although overcome above-mentioned scroll casing type centrifugal fan and there is technological deficiency in air pump, is applied in owing to will just having high wind to blow out effect, making that on household electric appliance, noise is difficult to descend under high-revolving driven by motor.
Summary of the invention
Technical problem to be solved in the utility model is to overcome present scroll casing type centrifugal fan, air pump and helical runner without the defective of the technology of shell-type blower existence for this reason, aims to provide box-like pair of wind wheel fan of a kind of impeller sets.
The purpose of this utility model also is 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 fan of the utility model impeller sets is characterized in that: wind wheel is comprised of inside and outside difformity structure two-part, and in wind wheel, half part is centrifugal straight impeller structure, and outer half part is spirality air drafting type structure.
as further optimization of the present utility model, above-mentioned wind wheel is arranged on inside spiral case by motor output shaft, the wind wheel layout of this inside and outside difformity structure, take full advantage of the strong advantage of spirality air drafting type air draught and the large advantage of centrifugal straight leaf air-out, make wind wheel under the not high drive of motor speed, the exhaust outlet of spiral case has the high wind of certain pressure to blow out, and shape that can same structure is installed at the other end of motor, reach the goal of the invention of box-like pair of wind wheel fan of the utility model impeller sets, make the blower fan air output larger, blast is higher, turn round more steady, quiet.
Working principle of the present utility model is such, motor is located in the middle of being arranged on the left and right spiral case, wind wheel is arranged on respectively the spiral case the inside by the output shaft at motor two ends by nut, electrical power rotates and makes axle two ends wind wheel rotation, special construction because of the left and right spiral case, wind wheel rotates to make and produces certain blast in spiral case, and in the spiral case of left and right, blast flows to exhaust outlet simultaneously, makes the spiral case exhaust outlet have high wind to blow out.
