Hand dryer with annular air exhaust
First Claim
1. A hand dryer with annular air exhaust, comprising:
- a casing which includes a coupling portion fastened to a wall and an air exhaust portion extended from and connected to the coupling portion, the coupling portion being formed at a thickness greater than that of the air exhaust portion to form a drop height section between them such that a moisture evaporation space is formed between the wall and the air exhaust portion, the air exhaust portion including two extension sections extended from the drop height section and a connection section connected to the two extension sections to form an annular hand drying passage communicating with the moisture evaporation space, the air exhaust portion further including a plurality of first nozzles located at the two extension sections and a plurality of second nozzles located at the connection section that are corresponding to the hand drying passage, the hand drying passage including a first opening and a second opening facing the moisture evaporation space at two ends thereof; and
an air supply device which is located in the coupling portion and includes an airflow guiding duct to direct air to the air exhaust portion, the first and second nozzles exhausting the air towards the hand drying passage such that moisture from a user'"'"'s hands is blown into the moisture evaporation space in an air flowing direction for evaporation.

Abstract
A hand dryer with annular air exhaust includes a casing and an air supply device located in the casing. The casing has a coupling portion and an air exhaust portion connected to the coupling portion. The air exhaust portion has two extension sections extended from the coupling portion and a connection section connected to the two extension sections to form an annular hand drying passage. The air exhaust portion includes a plurality of first nozzles and a plurality of second nozzles corresponding to the hand drying passage which has a first opening and a second opening at two ends. The air supply device has an airflow guiding duct to direct air to the air exhaust portion. The first and second nozzles exhaust the air towards the hand drying passage to form annular air exhaust, and thus hand drying angles are increased to dry hands faster.
