a casing having an opening at an upper portion thereof;

a door for opening and closing the opening;

a tub fixedly installed within the casing;

a drum rotatably installed within the tub;

a driving motor installed at an outer side of the tub;

an electric motor unit transferring rotary force of the driving motor to the drum;

a tub cover installed at an upper portion of the tub and including a guide unit for guiding water, which is discharged upwardly along an inner wall surface of the tub, to the inner side of the tub when the drum is rotated; and

a light emitting unit irradiating light to the interior of the tub.
