| description | The present application provides an impeller, a drainage pump, and an indoor unit of an air conditioning, and the impeller includes: an impeller shaft (11); long blades (12) fixedly connected to the impeller shaft (11) and extended outward along a radial direction of the impeller shaft (11); and a circular disc (13) including a plate-shaped structure (131) sleeved on an outer circumference of the impeller shaft (11), wherein the plate-shaped structure (131) is provided with at least one balance through hole (16) communicating front and rear sides of the plate-shaped structure (131). In the present application, at least one balance through hole (16) is provided on the plate-shaped structure (131), when water and air are sucked into the impeller cavity together, the air can be discharged out of the cavity through the balance through holes (16), which can reduce the vibration caused by the pressure difference during the operation of the impeller, thus reducing the noise generated during the operation of the impeller. |
