Abstract
An air inlet arrangement is provided in a laundry dryer for enhanced drying efficiency and rate. The dryer includes a drum with a rotating sidewall and a stationary rear bulkhead sealingly engaging the sidewall. A heater is provided on the outside of the rear bulkhead. The rear bulkhead includes a generally horizontally disposed air inlet in its lower half for introducing heated air into the drum. The heated air stream includes a hot inner core and a cool outer envelope so as to minimize the surface temperatures of the bulkhead and the sidewall and thereby prevent heat damage to clothing and laundry in the drum. The rear bulkhead includes a spirally ramped forward surface along which the air travels to impart a spiral airflow through the drum, thereby enhancing heat transfer between the air and the laundry in the drum.
