The apparatus is equipped with cover unit (1) fixed to a head portion of worker so as to cover at least the regions of nose and mouth of the worker, the cover unit capable of trapping the worker's breath. The cover unit has an exhaust opening and an air supply opening. Further, the apparatus is equipped with moisture recycle unit (2) fitted to the worker so as to simultaneously carry out the two processes consisting of the adsorption process of introducing moist air, effecting adsorption of the water contained in the air on an adsorbent and emitting dry air and the regeneration process of introducing dry air, effecting evaporation of the water adsorbed on the adsorbent into the dry air and emitting moist air. Still further, the apparatus is equipped with exhaust hose (3) connecting the exhaust opening of the cover unit to the moisture recycle unit and with air supply hose (4) connecting the moisture recycle unit to the air supply opening of the cover unit. The exhaust from the cover unit (1) is emitted via the moisture recycle unit into the dry room as dry air, and the dry air within the dry room is fed via the moisture recycle unit into the cover unit as moist air.

1. A device for collecting moisture contained in exhaled air of a worker who works in a dry room and returning the collected moisture to the worker together with inspired air, the device comprising: a cover unit adapted to be fixed to a head or a neck of the worker for covering at least a region of nose and mouth of the worker so as to collect the exhaled air of the worker, the cover unit having an exhaust opening and an air supply opening;a moisture recycle unit with an adsorption unit, the moisture recycle unit adapted to be worn by the worker for simultaneously performing two processes of an adsorption process and a regeneration process, the adsorption process consisting of taking in moist air, adsorbing the moisture contained in the moist air on the adsorption unit, and emitting the resulting dry air, the regeneration process consisting of taking in dry air, evaporating the moisture adsorbed by the adsorption unit into the dry air, and emitting the resulting moist air;an exhaust hose for connecting the exhaust opening of the cover unit and the moisture recycle unit; andan air supply hose for connecting the air supply opening of the cover unit and the moisture recycle unit,whereby moist air exhausted into the cover unit is dehydrated through the moisture recycle unit and the resulting dry air is emitted into the dry room, while dry air taken in from the dry room is humidified through the moisture recycle unit and the resulting moist air is supplied into the cover unit. 2. The device according to claim 1, wherein the cover unit is a helmet having a helmet opening for receiving the head of the worker adapted to be, put on and fixed to the head of the worker, the helmet comprising at least a transparent region for assuring the worker's viewing, an attachment member provided at an outer periphery or an inner periphery of the helmet opening for connecting to a collar part of a working clothes of the worker to seal the helmet opening, and a ventilation opening provided at an area of the helmet offset from the face of the worker for defogging. 3. The device according to claim 2, wherein the exhaust hose comprises a first exhaust hose ending and a second exhaust hose ending; and the exhaust opening comprises a first exhaust opening and a second exhaust opening, each of the two exhaust openings located on opposing sides of a lower part of the helmet; andthe air supply opening is formed at a back part of the helmet; andthe first exhaust hose ending extends from the first exhaust opening to a vicinity of the mouth of the worker in the helmet; andthe second exhaust hose ending extends from the second exhaust opening to a vicinity of the mouth of the worker in the helmet. 4. The device according to claim 1, wherein the cover unit is a mask, the mask having:a cap for covering the region of nose and mouth of the worker; andan attachment band attached to the cap for fixing the cap to a fixed position on a face of the worker. 5. The device according to claim 1, wherein the moisture recycle unit comprises a dehumidifier unit, the dehumidifier unit comprising:a casing whose interior is divided into two zones of an adsorption zone and a regeneration zone;a rotation shaft arranged along an interface between the adsorption zone and the regeneration zone inside the casing, and the rotation shaft is rotated by a motor;wherein the adsorption unit is an adsorption rotor having a honeycomb or corrugated structure, the adsorption rotor being coupled to the rotation shaft in such a manner that one portion of the adsorption rotor is located in the adsorption zone and the remaining portion of the adsorption rotor is located in the regeneration zone and the rotation of the rotation shaft causes the adsorption rotor to pass through the adsorption zone and the regeneration zone;a first air intake provided at the casing for taking moist air of the cover unit into the adsorption zone;a first air exit provided at the casing for emitting dry air from the adsorption zone;a second air intake provided at the casing for taking dry air of the dry room into the regeneration zone;a second air exit provided at the casing for emitting moist air from the regeneration zone, andthe moisture recycle unit further comprises:a first fan unit provided with an air suction opening and an air blow opening and the first fan unit is fixed to the dehumidifier unit, the air suction opening being connected to the exhaust hose, the air blow opening being connected to the first air intake of the dehumidifier unit;a second fan unit provided with an air suction opening a second and air blow opening and the second fan unit is fixed to the dehumidifier unit, the second air suction opening being connected to the second air exit of the dehumidifier unit, the second air blow opening being connected to the air supply hose;an attachment member fixed to the dehumidifier unit for wearing the dehumidifier unit on the worker; anda battery unit adapted to be worn by the worker so as to supply power to the first and second fan units, and the motor of the dehumidifier unit. 6. The device according to claim 1, wherein the adsorption unit comprises a first adsorption unit and a second adsorption unit, and the moisture recycle unit comprises: a casing provided with an air intake and an air exit, as well as first and second venting holes;a first chamber arranged in the casing for accommodating the first adsorption unit, the first adsorption unit having a honeycomb or corrugated structure;a second chamber arranged in the casing for accommodating the second adsorption unit, the second adsorption unit having a honeycomb or corrugated structure;a 2-position 4-port type switching valve arranged in the casing;a first pipe line arranged in the casing for connecting the air intake and a first port of the switching valve;a second pipe line arranged in the casing for connecting a second port of the switching valve and the first chamber;a third pipe line arranged in the casing for connecting the air exit and a third port of the switching valve;a fourth pipe line arranged in the casing for connecting a fourth port of the switching valve and the second chamber;a fifth pipe line arranged in the casing for connecting the first chamber and the first venting hole;a sixth pipe line arranged in the casing for connecting the second chamber and the second venting hole;a first fan unit provided with an air suction opening and an air blow opening and the first fan unit is fixed to the casing, the air suction opening being connected to the exhaust hose, the air blow opening being connected to the air intake of the casing;a second fan unit provided with a second air suction opening and a second air blow opening and the second fan unit is fixed to the casing, the second air suction opening being connected to the air exit of the casing, the second air blow opening being connected to the air supply hose;an attachment member fixed to the casing for wearing the casing on the worker; anda battery unit adapted to be worn by the worker so as to supply power to the first and second fan units,whereby when the switching valve is located at a first position, the first pipe line and the second pipe line are connected to each other, and at the same time, the third pipe line and the fourth pipe line are connected to each other, and when the switching valve is located at a second position, the first pipe line and the fourth pipe line are connected to each other, and at the same time, the third pipe line and the second pipe line are connected to each other.
