FLUID CIRCULATION COMPONENT WITH A LAYERED HEATING ASSEMBLY FOR A WASHING APPLIANCE

摘要

A fluid circulation component for a washing appliance may generally include a substrate defining a passageway therethrough for transporting fluid through the substrate. The fluid circulation component may also include a layered heating assembly formed directly onto an inner surface of the substrate. The layered heating assembly may include a heat insulating layer disposed directly on the inner surface, a heat conducting layer disposed radially inwardly from the heat insulating layer so as to form an outer wall of the passageway, first and second electrically insulating layers disposed between the heat insulating and conducting layers and a resistive heating layer positioned between the first and second electrically insulating layers. Additionally, when current is directed through the resistive heating layer, heat may be generated that is transmitted through the layered heating assembly to the heat conducting layer so as to increase a temperature of the fluid being transported through the passageway.
