A densified fluid barrier cleaning system is disclosed in which a pressure vessel encases a movable basket positioned so as to cross a barrier such that one opening of the pressure vessel resides in a first environment and a second opening of the pressure vessel resides in a second environment. A tubular basket within the pressure vessel is positioned such that its central longitudinal axis is aligned with both the first and second opening of the pressure vessel. Responsive to the successful completion of a cleaning cycle, soiled articles that are introduced to the basket via the first opening from the first environment can be removed through the second opening and into the second environment thus bridging the barrier without fear of introducing contaminants from the first environment to second environment.

A clothes care apparatus may include a cabinet, a first chamber formed inside the cabinet and configured to accommodate clothes, a first door configured to open or close the first chamber, the first door having a second chamber and configured to accommodate clothes, a second door configured to open or close the second chamber and rotatably coupled to the first door, and a spot cleaner disposed inside the second chamber and configured to spot clean the clothes accommodated in the second chamber. The spot cleaner is movable inside the second chamber to spot clean a target area of the clothes accommodated in the second chamber.

Provided is a compression system including a compressor configured to compress and discharge a refrigerant and comprising a refrigerant inflow port through which the refrigerant flows in and an oil recovery port for recovering oil, a plurality of oil separator configured to separate the oil which is included in the refrigerant discharged from the compressor and comprising a first oil separator into which the refrigerant discharged from the compressor flows and a second oil separator connected to the first oil separator in series along a travelling path of the refrigerant, a first recovery pipe configured to recover the oil from the first oil separator to the oil recovery port, and a second recovery pipe configured to recover the oil from the second oil separator to the refrigerant inflow port.

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.

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.

A washing machine may include: a washing tub having a first opening and a second opening; a pump; and a chiller; wherein a first flow path connects the second opening, the pump, the chiller, and the first opening so that pumping by the pump moves carbon dioxide from inside the washing tub through the second opening along the first flow path to pass through the pump, then along the first flow path to pass through the chiller so as to be cooled by the chiller, and then along the first flow path to pass through the first opening to be returned to the washing tub.

A washing machine is configured to perform washing using carbon dioxide. The washing machine includes a first housing that defines an opening and an inner space, a drum disposed in the inner space of the first housing and configured to receive laundry, a barrier that is coupled to the first housing and seals the opening of the first housing, and a second housing that faces a surface of the barrier and is coupled to the first housing. The barrier defines (i) a first space between the first housing and the barrier from leaking and (ii) a second space between the second housing, where the barrier is configured to block liquid carbon dioxide injected into the first space from leaking into the second space.

The present disclosure relates to a laundry treating apparatus including a pressure vessel for accommodating carbon dioxide therein, a storage tank for storing carbon dioxide therein to supply carbon dioxide to the pressure vessel, a distillation tank for storing carbon dioxide discharged from the pressure vessel to remove foreign substances dissolved in carbon dioxide discharged from the pressure vessel, and a gas supply pipe for connecting the distillation tank and the pressure vessel to each other to supply gaseous carbon dioxide stored in the distillation tank to the pressure vessel.

A laundry treating apparatus includes a pressure vessel configured to receive fluid and to maintain a pressure therein to be higher than an atmospheric pressure, a separator that divides the pressure vessel into a first chamber and a second chamber, a drum rotatably disposed in the first chamber and configured to accommodate laundry therein, a driver configured to rotate the drum, and a pump configured to cause the fluid to flow between the first chamber and the second chamber.
