摘要

The dryer has a housing (10) comprising a coupling area (15) and an air outlet area (16) with an infrared sensor (19). The outlet area has two extension areas (161) extending from the coupling area. A connection area (162) is connected with the extension areas for forming an annular hand drying passage (18), where the outlet area has two sets of nozzles (231, 241). An air supply device is arranged in the coupling area, and has an air flow guiding channel for guiding air to the outlet area. The nozzles circulate the air in the direction of the drying passage for forming an annular air outlet.
