Abstract

A lint filter for use in a clothes dryer includes a lint shield extending thereover with a door slidable over a through opening and a catch on the door to open the door as the filter is inserted into the dryer and to close the door as the filter is withdrawn. The lint shield covers the filter to prevent lint from accidentally falling therefrom and is hingedly connected to the filter for access during cleaning.

Claims

1. A lint shield for use on a removable lint filter for use in a dryer and having a filter element mountable in a gas stream to accumulate lint on a first side thereof, comprising:

a frame at least as large as the filter element and defining a through opening through which the gas stream flows to the filter element;

a door slidably mounted in said frame for selectively closing said through opening;

means for selectively securing said frame to the lint filter over the lint accumulating side of the filter element; and

means for moving said door to an open position when the lint filter and said lint shield are mounted in the dryer and for moving said door to a closed position when the lint filter and said lint shield are removed from the dryer.

2. A lint filter for use in a clothes dryer having an exhaust means for generating an air flow of lint laden air and a lint screen chute for holding a lint accumulating screen in the lint laden air flow, comprising:

a lint filter assembly having a filter frame and a filter web mounted on said frame, said filter assembly being insertable into the lint screen chute in the lint laden air flow;

a lint shield securable to said filter assembly at an upstream side and defining an opening through which the air flow passes;

means for closing said through opening when said lint shield is withdrawn from the chute; and

means for opening said through opening when said lint shield is inserted into the chute;

whereby said lint shield prevents lint from falling from said lint filter assembly upon removal from the dryer.

3. A lint filter as claimed in claim 2, wherein said closing means and said opening means includes:

at least one slidable door mounted to said lint shield over said through opening;

a catch on said slidable door; and

a catch engaging means secured on an inside of the chute to engage said catch as said lint shield is moved along the chute.

4. A lint filter as claimed in claim 2, wherein said catch is a snap-fit catch and includes a pair of spaced legs, and said catch engaging means is a probe for selective engagement between said spaced legs.

5. A clothes dryer, comprising:

a rotatable drum in which clothes are tumbled during drying;

means for causing an air flow through said drum during tumbling whereby said air flow entrains lint particles upon passing through said drum;

an air exhaust outlet for exhausting said air flow from said dryer;

a filter receiving chute extending into said exhaust outlet and having a user accessible aperture;

a lint filter assembly for insertion into said chute through said aperture for accumulating lint entrained in said air flow on a first side of said lint filter assembly;

a lint shield hingedly affixed to said lint filter for placement adjacent said first lint filter side, said lint shield including a frame defining a through opening and having a track at least on opposed sides of said through opening;

a door slidably mounted in said lint shield track and being slidable over said through opening;

retaining means for selectively holding said lint shield adjacent said filter assembly; and

catch means between said door and said filter receiving chute for opening said door as said lint shield is inserted into said chute and for closing said door as said lint shield is withdrawn from said chute.

6. A dryer as claimed in claim 5, wherein said catch means includes a snap-fit catch.

7. A dryer as claimed in claim 5, wherein said catch means includes a spring biased catch.

8. A dryer as claimed in claim 5, wherein said catch means includes a magnetic catch.

9. A dryer as claimed in claim 5, wherein said filter receiving chute is curved.

10. A dryer as claimed in claim 5, wherein said user accessible aperture is in a top panel of said clothes dryer.
