Centrifugation blade Main Function is the direction that changes air-flow, realizes motor and is arranged on outlet air end, makes motor and air duct cover board integrated.
In this programme, by motor, be directly installed on air duct cover board, realize with air duct cover board integrated, reduce the shaft length of motor, thereby reduce the vibration of centrifugation blade, by increasing the area of fan blade air draught side, improve the air quantity of fan blade, thereby greatly improve the efficiency of fan.
Further, between described motor and motor mounting groove, be provided with shakeproof washer.Be structure as a whole its Main Function of shakeproof washer is protection motor, reduces the vibration that motor produces.
Further, described fixed structure is retainer ring, and the opening diameter of retainer ring and the diameter of motor are suitable, and Fixing shrink ring is located at outside motor, and retainer ring is provided with connector, by connector, is fixedly connected with motor mounting groove.During installation, retainer ring is passed to motor, then be fixedly connected with motor mounting groove by connector.
Further, described connector comprises the retainer ring screw hole be located on retainer ring external diameter, is located at the mounting groove screw hole on air duct cover board, and screw is fixed on retainer ring, motor, shakeproof washer on motor mounting groove successively through retainer ring screw hole, mounting groove screw hole.
The installation steps that it is concrete: have motor mounting groove on air duct cover board, motor puts after shakeproof washer, are fixed on motor on the motor mounting groove of air duct cover board with retainer ring, accomplish fluently screw, again centrifugation blade is channeled on the axle of motor, finally cover on air channel, by buckle and air duct cover board, lock.
Further, described screw hole is 3, and the central angle of adjacent screw hole is 120 degree.By 3 screw holes, while making fixedly, integrally-built stability is stronger, makes motor can, because vibration comes off, not guarantee the stability of whole device in running.
Described bottom, air channel is provided with evaporimeter.Motor moves on to the area that changes air draught side after cover plate, strengthens the air quantity of centrifugation blade, and motor reduces the eddy current that evaporimeter top produces after moving on to cover plate, reduces the noise of fan blade and increases the flow of fan blade.
Compared with prior art, beneficial effect is: structure of the present invention is comparatively simple, and the few cost of mold members is lower, so be directly installed on air duct cover board by fan electromotor, realization is integrated with air duct cover board, reduces the shaft length of motor, thereby reduces the vibration of centrifugation blade.And in prior art, motor is arranged on air draught side, motor itself has used certain space, and motor place easily produces vortes interference efficiency; And in the present invention, motor is arranged on air side (cover plate place), air draught area has just increased the area of motor part, and the eddy current that minimizing motor produces is raised the efficiency, thereby greatly improves the efficiency of fan; Because space is little, be adapted at using on multiple wind cooling refrigerator.
