Abstract: A centrifugal pump for a kitchen appliance has a pump head and a pump body having a motor. The stator of the motor has a stator core, windings and an end cap fixed to one side of the stator core. The pump head has a volute and an impeller. The volute has a chamber with an inlet and an outlet. The chamber has an opening facing the pump body. The end cap is made of thermally conductive material and has an annular sidewall and a base plate. The sidewall surrounds the stator core. The base plate seals the opening of the chamber. Heat generated by the stator is transferred to liquid in the chamber via the end cap to cool the motor and to heat the liquid.

Abstract: A heating pump includes a pump body and a driving motor. The pump body includes a pump housing with a water inlet and a water outlet, a heating member fixed in an interior of the pump housing, and an impeller connected with the driving motor. The heating member includes fittings and a heating coiled pipe connected between the fittings and bent into an arc. The impeller is disposed at an upper part of the pump housing, one end of the driving motor is disposed adjacent the impeller, and the heating coiled pipe circles around a radial side portion of part of the driving motor. The heating pump has a rational design and high heat exchange efficiency. The safety auxiliary motor has a low requirement for power. The axial size of the water pump is significantly reduced.

Abstract: A brushed rotatory device (10) includes a stator, a rotor (14), an impeller (70), and a chamber (48) accommodating the commutator (16) and brushes (52) to contain debris from consumed brushes. The impeller causes air flow to dissipate heat generated by the rotatory device and may further carry the consumed brush debris away. The rotatory device includes flow channel(s) (72) which communicates with the impeller exhaust and accommodates absorbent or filtering materials (88) to trap the debris in the air flow. The commutation area may be double contained by using flange(s) (202) or wall(s) (42) to trap or confine a greater part of the debris in a localized region or to reduce noise from the rotatory device operations.
