Abstract

The invention relates to a synchronous water pump used for household appliances, in particular to a synchronous draining pump. The synchronous pump is characterized in that by changing the driving mode of a synchronous motor to an impeller and combining an impeller component structure with a rotor component structure, the cost of materials and manufacture is reduced greatly; by a directional braking structure, the rotating direction of the impeller is controlled effectively, the traditional centrifugal synchronous pump is changed into an axial flow pump and the draining efficiency and performance of the pump are improved; by changing a transmission structure, the driving of the motor is more smooth, the impact on the product is minimized, the noise is reduced, and the service life of the pump is prolonged; and an iron-core split-type design reduces the material cost and improves the electromagnetic performance. Therefore, the draining pump is characterized by comprising the following parts of an axial flow impeller 310 provided with a directional braking structure and accessories thereof; a magnetic ring for matching with the directional braking structure of the axial flow impeller 310 and accessories thereof; stainless steel sleeve 270 with highly-bright inner wall; and a stator core 240 of the split-type structure. The combination of the structures realizes the functions of buffering, directional rotating and axial flow type water draining.
