Humidity control apparatus

Abstract

A casing includes a first air passage in which outdoor air flows, and a second air passage in which room air flows divided by a divider plate. In each of the air passages, a humidity sensor is arranged on one of passage surfaces facing the air passage except for a surface of the divider plate.

1 . A humidity control apparatus comprising:
 a casing;   a divider plate arranged in the casing to provide a first air passage in which outdoor air flows, and a second air passage in which room air flows, with the divider plate interposed therebetween;   humidity controllers for controlling humidities of the room air and the outdoor air flowing in the air passages; and   humidity sensors arranged in the air passages, respectively, to detect air humidity in the corresponding air passages, wherein   each of the humidity sensors is attached to one of passage surfaces facing the corresponding air passage except for a surface of the divider plate.   
     
     
         2 . The humidity control apparatus of  claim 1 , further comprising:
 a support stage on which each of the humidity sensors is supported; and   an attachment provided on the passage surface of the corresponding air passage so as to detachably attach the support stage thereto.   
     
     
         3 . The humidity control apparatus of  claim 2 , wherein
 the attachment includes a rail extending along the passage surface of the corresponding air passage, and having a guide groove extending between longitudinal ends of the rail, and   the support stage includes a guide arranged at an end thereof to fit in the guide groove of the rail to be slidably supported on the rail.   
     
     
         4 . The humidity control apparatus of  claim 1 , wherein
 a maintenance opening facing both of the first air passage and the second air passage is formed in a side plane of the casing, and   both of the humidity sensors are arranged near the side plane of the casing.   
     
     
         5 . The humidity control apparatus of  claim 2  or  3 , wherein
 a maintenance opening facing both of the first air passage and the second air passage is formed in a side plane of the casing,   both of the humidity sensors are arranged near the side plane of the casing, and   the attachment includes a coupling section arranged to face the maintenance opening for fixing the support stage to the attachment.   
     
     
         6 . The humidity control apparatus of  claim 3 , wherein
 a maintenance opening facing both of the first air passage and the second air passage is formed in a side plane of the casing,   both of the humidity sensors are arranged near the side plane of the casing,   a plate is arranged to vertically stand at an end of the rail near the maintenance opening in such a manner that the support stage abut thereto, and   the plate includes a coupling section for fixing the support stage to the attachment.   
     
     
         7 . The humidity control apparatus of  claim 1 , wherein
 the casing includes humidity control chambers containing the humidity controllers, respectively, and a damper-carrying divider plate dividing the humidity control chambers from the air passages, and carrying a plurality of dampers for connecting/disconnecting the humidity control chambers to/from the air passages, and   one or both of the humidity sensors is attached to a surface of the damper-carrying divider plate facing the corresponding air passage.   
     
     
         8 . The humidity control apparatus of  claim 1 , wherein
 each of the humidity sensors is attached to one of the passage surfaces facing the corresponding air passage and opposing the divider plate.
