Abstract

Abstract A shoe drier has a base, a cap and a U-shaped hanging element. A motor is mounted on the base for driving an impeller to rotate. A heating chamber is disposed on the base for encasing a heater which emits thermal gas for drying a pair of wet shoes. The impeller transmits thermal gas to an upwardly semicircular channel which is complemented by matching a semicircular channel disposed on the cap. The cap has a downwardly semicircular. The U-shaped hanging element has an upper housing, and a first and a second lower housing. The U-shaped hanging element pivotally engages with the circular channels. A plurality of evenly spaced slots are provided on both upper parts of the both wings of the upper housing for guiding thermal gas to flow laterally out of the upper housing.
