ABSTRACT:
A warm-air hand drying installation has a floor-mounted pedestal with several drying apparatus around its periphery. A single fan supplies air to each apparatus via a central duct when any one of the apparatus is switched on. Each apparatus has a flap valve and a heater. The valve covers either the outlet of the apparatus or a side opening into the pedestal. When any one of the apparatus is switched on, the heater is energized and its valve opens to allow air flow to its outlet and onto the hands of the user. The heaters of other apparatus are not energized and their valves remain positioned such that air flow to the apparatus is directed internally between the pedestal casing and the duct, to the fan inlet. In this way, air flow can be maintained constant regardless of the number of apparatus in use. The fan remains on for a time longer than the heater.
