Device and implementation for filtering oil from water in an appliance

摘要

An appliance for washing objects is disclosed that effectively and energy-efficiently filters oil-based residue from a fluid such as washing fluid that drains from a basin in the appliance. In one illustrative embodiment, an appliance includes a novel filter assembly for filtering oil-based residue out of the washing fluid. The filter assembly includes a filter layer composed of a material that is both oleophilic and hydrophobic. The filter assembly forms part of a fluid distribution system that has different configurations. A first configuration allows for recirculating filtered wash fluid from an outlet of the filter assembly back into the basin of the appliance. A second configuration allows for draining both the washing fluid from the outlet of the filter assembly and the oil-based residue from a bypass zone of the filter assembly to an appliance outlet.

主权项

1. An appliance, comprising:
an enclosure comprising a basin; a filter assembly in fluid connection with the basin; and a fluid distribution system in fluid connection with the basin, the filter assembly, and an appliance outlet, wherein the filter assembly comprises:
a first filter layer that is both oleophilic and hydrophobic,a heat transference layer positioned between the basin and the first filter layer, the heat transference layer coupled to a heat sink, wherein the heat sink is located outside the flow path of the heated fluid,a first outlet in fluid connection with the first filter layer, the basin, and the appliance outlet, anda bypass zone in fluid connection with the first filter layer and the appliance outlet,wherein the heat transference layer is configured to reduce a temperature of a fluid entering the filter assembly before the fluid reaches the first filter layer.
