PROBLEM TO BE SOLVED: To make it possible to discharge dehumidification water definitely by providing a drainage means which drains automatically dehumidification water of a dehumidifier outside when it is accumulated to a definite amount and a back flow preventive means which prevents drain water from flowing back into a housing body in an underground housing device where the humidifier is disposed in the housing section. SOLUTION: A housing body 11 of an underground housing device is formed in a cube consisting of resin concrete-made four walls, a ceiling and a dirt floor. A dehumidifier 12 is set up on a floor surface 11a inside. In this case, a drain pipe (a drain hose) 13 is set up is the dehumidifier 12 so that it may rise upward from the rear surface. This drain pipe 13, which is provided with a check valve 14 or a back flow preventive means and so forth interposed near a ceiling 11c, is extended t the outside. The end of the drain pipe 13 is opened to a side ditch or the like on the ground. When the dehumidifier water of the dehumidifier 12 comes to a definite amount, the water is arranged to be drained outside the housing body 11 in automatic mode. The check valve 14 serves to prevent the water, if the water is once drained, from flowing back. |
