Abstract

The combination washer/dryer and method for operating a combination washer/dryer. The washer/dryer has a containment drum which receives wash water, and includes a perforated clothes drum which rotates within the containment drum. A heat plenum is provided in heat transfer relationship with the containment drum, and a source of heat coupled to the heat plenum supplies heat for water in the containment drum. During a drying cycle, hot air from the heat source supplied from the fire box to the containment drum for heating wash water during a washing cycle, and for supplying hot air during a drying cycle. A drying air plenum is connected to receive drying air from the source of heat, delivering the drying air to the top of the containment drum, where it enters the rotating basket. An exhaust plenum discharges hot air laden with moisture from the containment drum through a lint filter.

Claims

1. A lint removing apparatus for a washer-dryer comprising:

a filter disposed on a removable tray supported in an exhaust chamber which collects lint contained in drying air used in said washer dryer;

a nozzle aimed at one side of said filter and connected to valve which supplies water to said nozzle directing water to said filter prior to starting a wash cycle; and

a drain for collecting water and filter debris on the other side of said filter, said drain including an ejection nozzle for supplying a jet of water for emulsifying debris collected from said filter.

2. A lint removing apparatus for a washer-dryer comprising:

a filter disposed on a removable tray supported in an exhaust chamber which collects lint contained in drying air used in said washer dryer;

a nozzle aimed at one side of said filter and connected to valve which supplies water to said nozzle directing water to said filter prior to starting a wash cycle; and

a drain for collecting water and filter debris on the other side of said filter, said drain including an S trap-shaped portion which includes along said S trap-shaped portion an ejection nozzle for emulsifying said debris.
