Abstract:
A ventless combination closed-circuit washer and drier apparatus having a washing cycle and a drying cycle for a load of laundry, the apparatus comprising:a unitary washer housing having an insulated tub and a tumbler within the tub, the tub also having an air inlet and air outlet which allows air to flow through the tub, wherein air flowing from the air inlet is in communication with the tumbler; a desiccant housing containing a solid desiccant, the desiccant housing being located within the unitary washer housing and having an entrance and an exit, the entrance coupled to the air outlet and the exit coupled to the air inlet, thus allowing a continuous flow of internal air through the tub and desiccant housing in a closed air flow circuit; desiccant recharging means for providing a reversible removal of water adsorbed onto the desiccant using only internal air in the closed air flow circuit so that substantially the same volume of air is used throughout the washing cycle and the drying cycle for one load of laundry.
