  • Patent number: 10246859
    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.

  • Patent number: 10165908
    Abstract: A hand dryer with reduced air-intake noise includes a housing, a flow-guide plate, and an air supply module. The housing includes an accommodating space and a plurality of narrow air inlets. The flow-guide plate is disposed inside the accommodating space, but the flow-guide plate is not contacted with the housing. The flow-guide plate includes a plurality of narrow air guide holes. The air supply module is disposed inside the accommodating space, and includes a blower that extracts air inside the accommodating space to generate a drying air flow after being started and an air-guide piece connected to the blower to receive the drying air flow. An interval between the narrow air inlet and the narrow air guide hole interferes with transmission of a sound wave formed by the air flowing between the narrow air inlet and the narrow air guide hole, so that generated noise can be greatly reduced.
