Air shower apparatus

Abstract

An air shower for removing a particle from an object by blowing air to the object which includes at least one first outlet for discharging the air from the at least one first outlet toward at least a portion of the object so that a flow axis of the air flowing out of the at least one first outlet is swung frequently and alternately in a first swingable direction, and at least one second outlet for discharging the air from the at least one second outlet so that a flow axis of the air flowing out of the at least one second outlet is swung frequently and alternately in a second swingable direction which is different from the first swingable direction. The first swingable direction and the second swingable direction extend so as to be non-parallel to one another and to intersect one another.

1 . An air shower apparatus for blowing air from an air blower through a filter to an object such as a human body with a cloth or a product to blow off dust therefrom, comprising: 
 a plurality of outlets arranged on a wall surface of the air shower and capable of swinging directions of the airs blown respectively from the outlets with Coanda effect,    wherein each of the swung directions is capable of being arranged along at least one of a vertical direction, a horizontal direction and a combination of the vertical and horizontal directions, and    each of the outlets has an air inlet duct, a chamber duct and an outlet duct whose opening area is greater than an opening area of the inlet duct to form a step shaped air flow passage between the inlet and outlet ducts.
