Claims17
A fluid pump for a dishwashing appliance to motivate a fluid therethrough, the fluid pump comprising:
- a fluid impeller rotatably receivable within a tub of the dishwashing appliance;
- an electric motor in mechanical communication with the fluid impeller to motivate rotation thereof, the electric motor comprising a stator sealed within a potting material;
- a housing enclosing the electric motor therein, the housing receivable within a sump to which water is directed in the dishwashing appliance;
- a thermal barrier enclosing at least a portion of the electric motor therein;
- and
- an internal guide channel is defined within the housing between the thermal barrier and the housing, wherein the thermal barrier is positioned radially between the stator and the internal guide channel.
A dishwashing appliance defining a vertical direction, the dishwashing appliance comprising:
- a tub defining a wash chamber;
- a sump positioned at a bottom portion of the tub along the vertical direction, the sump comprising a bottom wall defining a recessed chamber;
- and
- a fluid pump in fluid communication with the sump to motivate a fluid therefrom, the fluid pump comprising:
- a fluid impeller rotatably positioned within the tub;
- an electric motor in mechanical communication with the fluid impeller to motivate rotation thereof, the electric motor comprising a stator sealed within a potting material;
- a housing enclosing the electric motor therein, the housing received within the sump;
- and
- a thermal barrier enclosing at least a portion of the electric motor therein.
