## Abstract

A washing machine lint trap has a long screen filter for removing particulates from the wastewater discharge as it flows therethrough and a rigid support rim coupled to the top side of the long screen filter. The long screen filter has a top side presenting an opening for insertion of a discharge drain hose attached to a washing machine and side screen material through which the wastewater flows while tapping particulates contained within the wastewater. The rigid support rim engaging a top side of a drainpipe to hold the lint trap in place when in use. The rigid support rim provides a supporting force to the long screen filter to keep the lint trap in place against the discharge flow of the wastewater.

## Claims

### Claim 1

A washing machine lint trap for use in filtering wastewater discharge in a residential setting, the lint trap comprises:
a long screen filter for removing particulates from the wastewater discharge as it flows therethrough, the long screen filter having a top side presenting an opening for insertion of a discharge drain hose attached to a washing machine and side screen material through which the wastewater flows while tapping particulates contained within the wastewater; and
a rigid support rim coupled to the top side of the long screen filter, the rigid support rim engaging a top side of a drainpipe to hold the lint trap in place when in use;
wherein the rigid support rim provides a supporting force to the long screen filter to keep the lint trap in place against the discharge flow of the wastewater.

### Claim 2 (depends on 1)

The washing machine lint trap according to claim 1, wherein the long screen filter accepts discharge drain hoses between 1 inch and 1½ inches in diameter.

### Claim 3 (depends on 2)

The washing machine lint trap according to claim 2, wherein the rigid support rim has an inner diameter matching the opening within the top side of the filter and an outer diameter greater than the outer diameter of a drainpipe.

### Claim 4 (depends on 3)
