Abstract
A plurality of shelves (14) having an storage space (13) are provided in the vertical direction, each of which is open in a front face and closed on the side of a back face with a space (16) by a cover (11), a clean air supply unit (20) comprising a fan (23) and a filter (22) is provided vertically in plural levels, and air inlets (17, 18A and 18B ) are formed on the side of the cover (11).
By driving the fans, air can be inspired from within the space, discharged, cleaned to a high cleanliness through a filter, and supplied from the side of the back face to the shelves. Cargos stored in the storage spaces are maintained at a high cleanliness by the clean air flowing from the back face to the front face. Since the space is subject approximately to the barometric pressure, any dirty air that has not passed through the filter is prevented from leaking to the side of shelves and to the outside from a joint of the cover. Because no space is required for placing various devices below the shelves, the entire structure can be simplified, thus reducing the size thereof, and enhancing efficient utilization of space.
