Abstract: A washing machine including a washing tub to wash laundry carbon dioxide; first and second storage tanks to store carbon dioxide; a first flow path connecting a compressor and the first storage tank; a second flow path connecting the compressor and the second storage tank; a first valve to open and close the first flow path; a second valve to open and close the second flow path; and a controller configured to, upon completion of a laundry washing operation, operate the compressor to compress carbon dioxide received from the washing tub, open the first valve to move the compressed carbon dioxide from the compressor along the first flow path to the first storage tank, and, based on pressure in the washing tub, close the first valve and open the second valve to move the compressed carbon dioxide from the compressor along the second flow path to the second storage tank.

Abstract: A washing machine may include a washing tub configured to wash laundry with carbon dioxide; a compressor configured to compress the carbon dioxide discharged from the washing tub; a first storage tank connected to the compressor and configured to store carbon dioxide; a second storage tank connected to the compressor and configured to store carbon dioxide; a distillation tank to accommodate carbon dioxide and foreign matter discharged from the washing tub and to evaporate the carbon dioxide so that the foreign matter and the carbon dioxide evaporated in the distillation tank are separated; and a first pressure relief valve on a first discharge flow path between the washing tub and the second storage tank, and configured to open in response to pressure in the washing tub being greater than or equal to a first pressure so that carbon dioxide in the washing tub is moved to the second storage tank.

Abstract: A washing machine may include a storage tank to store carbon dioxide; a tub to wash laundry using the carbon dioxide; a distillation tub to separate carbon dioxide discharged from the tub and foreign substances contained in the carbon dioxide; a compressor to compress the carbon dioxide discharged from the tub and move the carbon dioxide to the storage tank; a rotatable drum inside the tub; a driving device to drive rotation of a rotatable shaft connected to the rotatable drum to rotate the rotatable drum; a pipe configured to pass inside of the tub to exchange heat of the compressed carbon dioxide with the tub; and a blade protruding from the rotatable shaft so that the blade is rotated by rotation of the rotatable shaft to circulate air inside the tub to spread the heat of the compressed carbon dioxide emitted from the pipe.
