Filed: 1992-01-14
Abstract: PURPOSE:To eliminate such a troublesome handling that an adapter is attached and detached every time a hair dryer is alternately used as wall-mounted, table-top or hand-held type and improve the rewinding performance of a power cord after the dryer is used, by a method wherein a wall mounting angle is detachable from a handle and the wall as well and rotatable on the handle. CONSTITUTION:When a hair dryer is used as wall-mounted type, holes 14g of a wall- mounting angle 14 are fitted on a fitting on a wall so as to detachably mount the hair dryer on the wall. When the dryer main body 1 is turned counterclockwise and clockwise, it turns on columnar protrusions 12b and 13b on a horizontal part. The dryer main body 1 can be also turned up and down on a mounting boss 10, and moreover when the dryer main body 1 is pulled forward, it can be removed from the mounting angle 14 so that the usability is improved. When the dryer main body l is taken off from the wall together with the mounting angle 14, it can be used as hand-held or table-top type. When a user grips a handle 9, the dryer main body 1 is prevented from slipping off by the mounting angle 14 and upper and lower stoppers 12, 13. When a power cord 18 is rewound up after the dryer is used, it is surely prevented from slipping off by the stoppers 14f, thus the hair dryer can be easily put in order after used.
