<p>PURPOSE: To dehumidify the inside of a box or the like having the respiratory action over a long time and to positively perform dehumidifying action by particularly utilizing infrared rays abundantly obtainable from the surroundings. CONSTITUTION: This dehumidifier comprises a cylindrical casing 1 fitted to the bottom surface of a vessel 10 and forming an air passing path 11 for making the inside and the outside of the vessel 10 communicate with each other and which consists of an inner cylinder 1a and an outer casing 1b, air passing bodies 2 in which waterproof membranes 20a, 20b, 20c having moisture permeable fine through pores are arranged at intervals inside the inner cylinder to shield the air passing path, an aluminum ring 3 as a temperature forming means for increasing the vessel side temperature the inner cylinder higher than the ventilation side temperature therein by infrared rays with which the cylindrical body 10 is irradiated from the outside.</p> |
