Abstract

The present disclosure relates to a washing machine comprising a first housing having an opening and a space into which a drum accommodating laundry is inserted, a storage tank configured to store carbon dioxide to be supplied to the drum, and a first compressor and a second compressor, each of which compresses the carbon dioxide discharged after completion of washing in the drum and enables the compressed carbon dioxide to flow into the storage tank. Washing is performed after carbon dioxide is introduced into the drum. After completion of the washing, the first compressor and the second compressor are operated in parallel to compress carbon dioxide. When internal pressure of the drum is lowered by a first preset pressure, a revolutions per minute (rpm) of the second compressor is changed.
