摘要

Disclosed is an apparatus for purifying a washing solvent, comprising: a housing which has an openable door; a tub which is installed inside the housing; a drum which is installed inside the tub to be able to rotate, and stores laundry inserted into the housing through the openable door when the openable door is opened; a washing solvent tank which stores a volatile washing solvent; a temporary storage tank which is located higher than the washing solvent tank; a pump which presses the washing solvent stored in the washing solvent tank to move the same to the temporary storage tank; a pre-processor which prevents turbulence of the washing solvent and into which the washing solvent stored in the temporary storage tank falls by gravity and flows; a running water separator which separates moisture and foreign substances from the washing solvent and into which the washing solvent discharged from the pre-processor falls by gravity and flows; and first and second gas delivery tubes which guide a washing solvent gas formed by vaporizing a part of the washing solvent flowing into the temporary storage tank and the pre-processor to the inside of the tub from the temporary storage tank and the pre-processor. The washing solvent from which moisture and foreign substances are separated is moved from the running water separator to the washing solvent tank, and the washing solvent gas of the temporary storage tank and the pre-processor is moved to the inside of the tub through the first and second gas delivery tubes in a state where the openable door is closed, thereby not being discharged to the outside of the housing.
