<p>PROBLEM TO BE SOLVED: To deodorize the interior without increase in the effective area in the room by providing a duct which has an intake port opened to the interior floor surface or side surface and an exhaust port opened to the interior ceiling or side surface, and installing a deodorizing material in the intake port, and installing a fan in the exhaust port. SOLUTION: An intake port 7 is provided on the base of the side surface of a room 1, an exhaust port 9 is provided in the substantially central part of a ceiling, and the intake port 7 and the exhaust port 9 are communicated with each other by a duct 6. An urethane foam is stuck to the inside of the duct 6 by an adhesive in such a manner that heat exchange is not performed in the duct 6. A deordorizing material 8 formed by bearing a deodorizing element in a honeycomb structure is arranged in the intake port 7, a fan 4 for circulating the interior air is fitted to the exhaust port 9, and a dust collecting filter 3 is provided right under the fan 4. The interior air is sucked from the interior air by rotating the fan 4, and simultaneously malodor component is adsorbed and decomposed to be removed by the deodorizing material 8, so that only pure air is again discharged from the exhaust port 9.</p> |
