<p>PURPOSE:To reduce the effect of wind in the dehumidifier which uses a humidity permeable membrane and is used in a living house, etc., by supporting the humidity permeable membrane so as to be movable to the face direction according to the pressure difference between both sides of the membrane, and providing plain plates not permeating vapor to both sides of the membrane with clearances between. CONSTITUTION:The humidity permeable membrane 1 is supported in a frame 2 by a sheet type flexible material 6 fixed to the periphery of the membrane 1, and the plain plates 5 of non permeability is provided to both sides of the membrane with clearances for fans 4 generating convection between. When the pressure difference difference is generated between the outdoor side and the indoor side due to wind, the pressure forced works to the membrane 1, and the membrane 1 is pressed to one of the plain plates 5 because of the elongation of the sheet 6 fixed to the periphery of the membrane 1 with a result that vapor is prevented from permeating the membrane 1. Consequently, the membrane keeps the humidifying function without the effect of outdoor wind.</p> |
