  • Patent number: 4145821
    Abstract: After rugs have been cleaned in place in dwellings using liquids, even though the cleaning operations involve the vacuuming of then dirty cleaning liquids from the rug, considerable moisture is left in the rugs. To remove this residual moisture this rug dryer is centered over a large rug area. Then during drying operations the dryer blower fan draws room air in from above and directs the room air downwardly toward the rug for distribution along the floor and through the rug fibers in multiple directions away from the fan, while being directionally controlled near the rug, below a continuous floating and fluttering layer of an air impervious material extended over a large area of the rug. In a preferred embodiment, the axis of the dryer blower fan is arranged vertically and the fan housing of the blower assembly is mounted above the rug on small diameter legs. Also the fan housing of the blower assembly has a spaced outer ring to which the air impervious material is attached.
