Abstract: A hand cleaning system includes four cleaning devices, a sensing device and a control device. Cleaning services respectively provided by the four cleaning devices are different. The control device controls each of the cleaning devices and the sensing device. The control device is set with procedure control data, which causes the control device to sequentially activate the cleaning devices when read. The control device has a first operation mode in which each of the cleaning devices can be independently activated, and a second operation mode in which the procedure control data is read upon acquiring a procedure activation signal to temporarily control the cleaning devices to operate. The control device in the second operation mode determines whether a usage time of each of the cleaning devices satisfies a minimum usage time condition to accordingly demand a user to properly perform hand cleaning.

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.
