Abstract

The invention discloses a draining pump and a washing household appliance with the draining pump. The draining pump is provided with a motor and an impeller, wherein the motor comprises a stator, a rotor, and a rotating shaft, the stator comprises a stator iron core, a stator winding and a stator insulation framework; the rotor adopts an outer rotor structure formed by injection molding of a permanent magnet and wraps the outer side of the stator; and a first end of the rotating shaft is installed on the rotor, a second end of the rotating shaft is installed in the stator, and the impeller isarranged on the rotor in the extending direction of the rotating shaft.

Description

【Technical field】 [0001] The invention relates to a drainage pump, which is applied to washing household appliances, such as a dishwasher or a washing machine. 【Background technique】 [0002] Existing dishwasher drainage pumps mostly use an inner rotor structure motor mechanism. The two ends of the rotor are supported by a bearing to realize the rotation function. The impeller is installed at one end of the rotor shaft, and the rotation of the rotor drives the impeller to rotate. The rotation in the middle realizes the drainage function. The stator of the live part of the drainage pump and the rotor of the water-contacting part are separated by a plastic shell, which not only ensures the safety when the power is turned on, but also provides a space for the rotor, and grease is injected into the rotor space for lubrication. Due to the large number of structural components, grease needs to be injected during assembly, which makes the assembly process more complicated. 【Cont...
