A nozzle unit of a liquid spray apparatus is constituted by a conduit tube having an outer portion spreading and curvature shape upper inner wall, a disc shape flat plate cover arranged on an upper portion of the conduit, and a coupling. Between the flat plate cover and the conduit tube a spray port of the nozzle unit is formed. From the spray port of the liquid spray apparatus, a thin film liquid (a thin film spray body) is sprayed. To this thin film liquid a swirl component (a squint direction component) is given and run down, to the thin film liquid a liquid pressure fluctuation generates, the pulsation movement is given to the thin film liquid. In a case where a nozzle unit has a ring shape spray port a melon shape spherical thin film spray body is formed and in a case where a nozzle unit has a linear shape spray port a circular shape thin film spray body is formed. The liquid spray apparatus in which a thin film spray body can reach to a desirable run down point without the scattering of the liquid droplets and without the film cut off according to the pulsation can be obtained.

Fluid spray apparatus

A washing/drying machine capable of effecting washing and drying as a continuous process. Washing, rinsing, dehydrating and drying are performed while a rotary basket is retained in a vertical position. After the dehydration the rotary basket is inclined and is rotated on its axis, so that an opening end of the rotary basket is located slightly higher than the horizontal. In this state, hot air for drying is blown into the rotary basket from the opening side.
