Abstract
The utility model mainly relates to a centrifugal ventilation fan. The utility model comprises a spiral casing, a vane wheel, a motor and a motor bracket. The utility model is characterized in that the motor is in the type of double shaft extension and outer rotor, and is installed in the vane wheel with single air intake; a one end of a shaft of the utility model is fixed on a lateral plate of the spiral casing, and the other end of the shaft of the utility model is fixed on a bracket for an air inlet. The utility model can be widely used on a suspended ceiling type air conditioner and other occasions requiring lower mounting height.
Description
The utility model belongs to ventilation equipment, relates generally to centrifugal fan.
At present, domestic and international air-conditioning unit centrifugal fan, when the work running, its arbor all is parallel to ground, can not use by vertical ground.Because impeller diameter can not be too small, otherwise can make flow, pressure head too small, the noise height, can not satisfy usage requirement, and the increasing impeller diameter, the spiral case radial dimension can increase, and the height when centrifugal fan is installed and used is just big, some design of air conditioning and ventilation can not be implemented, influenced the blower fan using scope.
But the purpose of this utility model provides the ultrathin centrifugal fan that a kind of vertical level is used.
The utility model comprises spiral case, impeller, motor and support of motor, it is characterized in that motor is that twin shaft is stretched external rotor type, is installed in single intake air impeller, and its axle one end is fixed on the spiral case side plate, and the other end is fixed on the intake grill support.
Motor one end of the present utility model adopts two-way radial bearing.
The utility model can be widely used in ceiling air conditioner assembly cover and other setting height(from bottom)s require less occasion.Because motor of the present utility model adopts twin shaft to stretch, two ends are fixed, and an end adopts two-way radial bearing, so, can use perpendicular to horizontal plane, motor is contained in the impeller, has reduced height, make operate steadily reliable.
The utility model is described in further detail below in conjunction with accompanying drawing:
Accompanying drawing is the utility model embodiment's a structural representation.
Among the figure, the impeller 5 that is arranged in spiral case 1 is provided with motor 2, and motor 2 one ends are installed on the support 3, and the other end is fixed on the spiral case side plate axle sleeve.When 5 rotations of motor 2 impeller, air-flow enters from intake grill 4, flows out from exhaust outlet 6.
Claims (2)
1, a kind of ultrathin centrifugal fan, comprise spiral case, impeller, motor and support of motor, it is characterized in that motor is that twin shaft is stretched external rotor type, is installed in single intake air impeller, its axle one end is fixed on the spiral case side plate, and the other end is fixed on the intake grill support.
2, ultrathin centrifugal fan according to claim 1 is characterized in that motor one end adopts two-way radial bearing.
