    • In a conventional water discharge pump assembled in an air conditioner, the rotation of a blade wheel produces cavitation to cause a problem with quietness. A vertical shaft water discharge pump of the invention has a rotor (23), a casing (20), a cover (22) that forms, together with the casing (20), a pump chamber (21) in which the rotor (23) is received, a suction pipe (25) forming a suction path (24) communicating with a lower end central portion of the pump chamber (21), and a discharge port (26) communicating with the pump chamber (21). The rotor (23) has a rotor shaft (40) connected at its upper end section to a drive motor (16), a circular main plate (42) cocentrically integrally connected to the rotor shaft (40), pins (43) projecting from the main plate (42) substantially in parallel to the axis of the rotor shaft (40), and uniformly pressing sections (44, 46) formed in the main plate (42) and communicating between the front surface side and the back surface side of the main plate (42).
    • 在组装在空调器中的常规排水泵中,叶轮的旋转产生空化以产生安静的问题。 本发明的立式排水泵具有转子(23),壳体(20),与壳体(20)一起形成的盖子(22),其中转子(23) ),形成与所述泵室(21)的下端中央部连通的吸入路(24)的吸入管(25)和与所述泵室(21)连通的排出口(26)。 转子(23)具有在其上端部连接到驱动马达(16)的转子轴(40),与转子轴(40)中心地一体地连接的圆形主板(42) 所述主板(42)基本上平行于所述转子轴(40)的轴线,并且形成在所述主板(42)中并且在所述主板(42)的前表面侧和所述背面侧之间连通的均匀的按压部(44,46) 主板(42)。
