Abstract
An air-cushion nozzle for an air-treatment device has a hollow housing having an upper wall formed by a pair of end plates and a central plate. The end plates form with the central plate a pair of generally parallel slots directed upwardly generally toward each other and one of the end plates is formed adjacent and along a full length of the respective slot with an array of throughgoing holes. The central plate is substantially imperforate between the slots. The housing is internally pressurized, normally with hot air, to form from each slot an upwardly directed elongated jet of air and from each of the holes a respective upwardly directed further jet of air.
