An improved laundry drier which includes an outer case as well as an inner case and a tub which is rotationally driven. There is provided a heating housing having heating elements contained therein. A blower is located beneath the heating elements in the heating housing. A first electromagnetic valve is located in a passage of a suction duct. A branch duct is formed into the passage and is in fluid communication with a suction end of the blower. A second electromagnetic valve is formed in the branch duct to control fluid communication between the passage of the suction duct and a spraying duct. There is provided a vacuum apparatus disposed therein. Hot air may be circulated through the spraying duct and finally through the blower and the heating elements in the heating housing during a drying process. The mixture of the used hot air and steam obtained after drying may be exhausted from the tub and brought to water to be cooled and condensed before it is discharged by the vacuum device during an exhaust process.
