Patent number: 5525106Abstract: 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.Type: GrantFiled: April 5, 1994Date of Patent: June 11, 1996Assignee: Daifuku Co., Ltd.Inventors: Yukio Iizuka, Kibo Miyajima

Patent number: 5500028Abstract: An article storing arrangement having a filter device 11 mounted to the back side of an article storing shelf assembly 4, the filter device 11 having a mounting frame member 12 removably attached to a support frame 6, a filter 14 provided at a position corresponding to an opening of the mounting frame member 12, and a cover member 17 covering the outer surface of the filter 14, the cover member 17 having an air inlet port 20 at the top thereof. The filter device is mounted to the support frame through the mounting frame member. Therefore, when a filter performance test is required in an actually mounted condition, such a test can be carried out simply by fixing the filter device to the mounting frame member. Accordingly, such performance test can be effected with far much greater ease than in the case where a performance test is carried out, for example, by attaching the filter, cover member, and the like directly to the support frame.Type: GrantFiled: May 2, 1994Date of Patent: March 19, 1996Assignee: Daifuku Co., Ltd.Inventor: Yukio Iizuka
