Title:
HEARING AID DRYER
Document Type and Number:
WIPO Patent Application WO2004112422
Kind Code:
A3
Abstract:
An apparatus is disclosed for removing moisture from electronic devices such as hearing aids (24), using a desiccant material (23). The desiccant material (23) is regenerated in place with heat from a heater (6) placed in close proximity to said desiccant (23), said heater (6) being activated when the cover (2) of the apparatus is open to the atmosphere. Drying of the hearing aids takes place when the hearing aids are placed in the apparatus and it is closed. A microswitch (8) is engaged by a protrusion (9) on the cover (2) thus deactivating the heater (6). Power is supplied by an external power source through a connector (7). Heat is not applied during drying to avoid potential damage to the hearing aids or other electronic device.
