Description

上記目的を達成するために、本発明による排水ポンプは、回転羽根と、前記回転羽根が収容された第１室を有するポンプ本体と、前記ポンプ本体の上方に配置され、前記第１室から流出する流体を外部に排出可能な第２室を有するモータ支持部材と、前記モータ支持部材によって支持されたモータと、前記第１室と前記第２室との間に配置された隔壁と、前記隔壁に設けられた貫通孔と、前記貫通孔を通過して配置され、前記モータからの回転力を前記回転羽根に伝達するシャフトとを具備する。前記隔壁は、リング状本体部と、前記リング状本体部の内側部分の下面に設けられた水流誘導表面とを備える。前記水流誘導表面は、前記リング状本体部の外側部分の下面よりも上方に凹んだ凹部空間を規定しており、前記リング状本体部の外側部分の下面に連なる部分から径内方向に向かうにつれて徐々に深くなる外側表面と、当該外側表面から更に径内方向に向かうにつれて徐々に浅くなる内側表面とを備え、前記水流誘導表面は、前記リング状本体部の下部から前記外側表面に沿って前記凹部空間内に流入した水流を、前記内側表面により水平方向または斜め下方に向けて誘導する。 In order to achieve the above object, a drainage pump according to the present invention includes a rotary vane, a pump main body having a first chamber in which the rotary vane is accommodated, an upper portion of the pump main body, and an outflow from the first chamber. A motor support member having a second chamber capable of discharging a fluid to be discharged to the outside, a motor supported by the motor support member, a partition wall disposed between the first chamber and the second chamber, and the partition wall And a shaft that is disposed through the through hole and that transmits the rotational force from the motor to the rotary blade. The partition includes a ring-shaped main body and a water flow guide surface provided on the lower surface of the inner portion of the ring-shaped main body. The water flow guiding surface defines a recessed space that is recessed above the lower surface of the outer portion of the ring-shaped main body, and as it goes in a radially inward direction from a portion that continues to the lower surface of the outer portion of the ring-shaped main body. An outer surface that gradually becomes deeper and an inner surface that gradually becomes shallower from the outer surface toward the radially inward direction, and the water flow guiding surface extends from the lower part of the ring-shaped main body portion along the outer surface. The water flow flowing into the recessed space is guided horizontally or obliquely downward by the inner surface .

いくつかの実施形態における排水ポンプにおいて、前記水流誘導表面は、前記外側表面と前記内側表面との間に、水流の向きを変える水流方向変更部を備えていてもよい。前記水流方向変更部は、前記内縁部よりも上方に位置していてもよい。 In the drainage pump according to some embodiments, the water flow guide surface may include a water flow direction changing unit that changes a direction of the water flow between the outer surface and the inner surface . The said water flow direction change part may be located above the said inner edge part.

前記外側表面は、径内方向に向かうにつれて傾きが変化する面であってもよい。 Before Kisotogawa surface may be a surface, the slope of which varies toward the radially inward direction.

いくつかの実施形態における排水ポンプにおいて、前記水流誘導表面は、前記外側表面に凸曲面を備えていてもよい。 In the drainage pump in some embodiments, the water flow induction surface may include a convex curved surface on the outer surface .
