<p>A low-humidity working apparatus comprising a housing (8) forming a working chamber (9), a dehumidifying apparatus (18), and air supply means. The metal housing (8) forming the working chamber (9) is provided with a laterally elongated operating hole (30), a plurality of strip flexible sealing members are arranged adjacent to each other and suspended in this operating hole (30), and a laterally elongated window hole (31) is disposed in the vicinity of and above the operating hole (30) and closed by a light-transmitting window plate. The dehumidifying apparatus (18) circulates the air in the working chamber (9) by sucking the air therefrom, cooling the sucked air by an evaporator (48) of a compression refrigerating machine (41), dehumidifying the cooled air by a dehumidifying rotor (61) carrying a dehumidifying agent, and returning the low-humidity air from the dehumidifying rotor (61) to the working chamber (9). The air supply means supplies outside air to the dehumidifying rotor (61) via an evaporator (58) to keep the working chamber (9) at the positive pressure and prevent the outside air supplied through the operating hole (30) from entering the working chamber (9). Thus, the operation can be conducted at an excellent workability by inserting the hands through the operating hole (30) into the working chamber (9), the interior of which is kept at low humidity. <IMAGE></p> |
