  • Publication number: 20180077900
    Abstract: A pet drying room, including: a drying room having a space formed to accommodate a pet therein; a mounting hole perforated in the front portion of the drying room; a discharge hole perforated in the rear portion of the drying room; and a dust collection filter positioned at the rear side of the drying room to close the discharge hole and having a plurality of fine holes formed therein. After accommodating a pet in the drying room, a conventional hair dryer is attached to the mounting hole to inject warm air to the inside of the drying room and conveniently dry the pet in the drying room. Therefore, various electrical and mechanical elements previously used in conventional pet dryer devices are eliminated, thereby significantly reducing unit costs, such that the pet drying room can be used by normal home users without the burden of expenses and ensure versatile use thereof.
