Abstract: A washing machine includes a first housing configured to include an opening formed therein and a space in which a drum for accommodating laundry is inserted, a barrier configured to seal the opening and coupled to the first housing, and a second housing configured to seal one surface of the barrier and coupled to the first housing. Carbon dioxide is injected into the drum to perform washing. The barrier prevents liquid carbon dioxide injected into a space provided by the first housing and the barrier from flowing into a space provided by the second housing and the barrier.

Abstract: A washing machine includes a first housing (100) configured to include an opening (104) formed therein and a space in which a drum (350) for accommodating laundry is inserted, a barrier (400) configured to seal the opening (104) and coupled to the first housing (100), and a second housing (200) configured to seal one surface of the barrier (400) and coupled to the first housing (100). Carbon dioxide is injected into the drum (350) to perform washing. The barrier (400) prevents liquid carbon dioxide injected into a space provided by the first housing (100) and the barrier (400) from flowing into a space provided by the second housing (200) and the barrier (400).
