Cross flow fan having a plurality of unit fans assembled in succession with the unit fans twisted from each other at sides, and an air conditioner fitted with the same. The unit fan includes an annular rim, and a plurality of impellers arranged on a side of the rim vertical to, and along a circumference of the rim. The present invention provides a cross flow fan extension lines from the impellers of the unit fan have a phase difference with the extension lines from the impellers of an adjacent unit fan. The air conditioner includes a casing having an inlet and an outlet, an indoor unit inclusive of an indoor heat exchanger provided in rear of the inlet inside of the casing, and a cross flow fan having a plurality of unit fans assembled at sides in succession, with the unit fans twisted from each other, the cross flow fan being provided inside of the casing, and the unit fan having an annular rim, and a plurality of impellers arranged on a side of the rim vertical to, and along a circumference of the rim, and an outdoor unit having an outdoor heat exchanger and a compressor, the outdoor unit connected to the indoor unit with refrigerant pipe.

Cross flow fan and air conditioner fitted with the same

Cross flow fan, and air conditioner fitted with the same, the cross flow fan including a plurality of annular rims arranged at regular intervals along a horizontal direction, and a plurality of blades on a side surface of the rim vertical thereto, and along a circumference direction of the rim, wherein pitch angles between two adjacent blades are not regular, the pitch angle taking a center of the rim as an apex, and a number of blades are 32 or 35. The pitch angles of the blades are designed by a computer optimization method taking a number of the blades and the like as parameters.

A cyclone collector for a vacuum cleaner is disclosed. The cyclone collector comprises a cylindrical cyclone body, an air inlet connected in the middle of an outer circumference of the cyclone body in a tangential direction, dust outlets connected to both ends of the outer circumference of the cyclone body in a tangential direction, a dust box in communication with the dust outlets for collecting dust coming through the dust outlets, a pair of air outlet tubes for discharging an air inside of the cyclone body, and a guide piece provided in the middle of an inside surface of the cyclone body for smoothly dividing and guiding the air drawn through the air inlet to the air outlet tubes, respectively.
