Abstract
Abstract The present invention provides a filter assembly adapted to be connected the water discharge hose of a washing machine. The filter assembly comprises a body having a tubular inlet member and a tubular outlet member which are coaxial but axially spaced from each other. A plurality of circumferentially spaced fins are secured to and extend outwardly from the tubular members and the inlet member is connected to the water discharge hose from the washing machine. A tubular mesh filter element is disposed around the fins and has one end secured to the inlet member and its other end secured to the outlet member. In addition, a cone is positioned in between the inlet and outlet members which diverts the water flow from the water discharge hose outwardly towards the filter element.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
193 words
A filter assembly for use with a water discharge hose of a washing machine comprising: a body having an inlet tubular member and an elongated outlet tubular member, said members being substantially coaxial and axially spaced from each other, each tubular member having an inner end which faces the inner end of the other tubular member, and an outer end, a plurality of circumferentially spaced fins secured to and extending outwardly from said tubular members, means for fluidly connecting said outer end of said inlet tubular member to the discharge hose, a tubular filter element, means for attaching one end of said filter element to said inlet member and the other end of said filter element adjacent said outer end of said outlet tubular member so that said filter element encloses said fins and so that said inner end of said outlet member is positioned at a midpoint of said filter element, and means positioned between said inner ends of tubular members for diverting fluid flow from said outer end towards said inner end of said inlet member radially outwardly around the inner end of said outlet member and toward said filter element.
