DISCHARGE PUMP AND AIR CONDITIONER EQUIPPED WITH THE SAME

PROBLEM TO BE SOLVED: To provide a discharge pump of high pump efficiency with little power consumption of a motor and reducing noise by forming a passage with smooth flow from the suction to discharge of a fluid to be discharged while fixing a relative position between a pump body and a rotation body into a prescribed position without needing a special tool. SOLUTION: The rotation body is provided with a shaft part connected to a drive shaft of a driving motor; a first blade member with a large diameter provided at the shaft part to extend radially outward with respect to the axis of the shaft part; an approximately ring-like annular member provided at the lower end of the first blade member to extend radially outward with respect to the axis of the shaft part; an approximately cylindrical suction port extending downward from the inner diameter side of the annular member and projecting from a lower end opening part of a pump chamber; and a second blade member with a small diameter formed inside the suction port radially outward with respect to the axis of the shaft part to reach the internal wall of the suction port.
