Abstract: A washing machine includes: a frame, a drum receiving laundry, a washing chamber including (i) a first housing defining an opening and a space into which the drum is inserted, (ii) a barrier surrounding the opening and coupled to the first housing, and (iii) a second housing surrounding a first surface of the barrier and coupled to the first housing, a storage tank receiving carbon dioxide to be supplied to the drum, a distillation chamber separating contaminants dissolved in liquid carbon dioxide, an electronic unit, and a configuration unit. The configuration unit includes a pipe moving the carbon dioxide, a first compressor and a second compressor compressing the carbon dioxide discharged after washing is completed in the drum and moving the compressed carbon dioxide into the storage tank, and an oil separator separating oil from the carbon dioxide compressed in the first compressor and the second compressor.

Abstract: A washing machine is configured to perform washing using carbon dioxide and includes a first housing that defines an inner space and an opening, a drum disposed in the inner space of the first housing and configured to accommodate laundry, a barrier that covers the opening of the first housing and is coupled to the first housing, a second housing that covers a surface of the barrier and is coupled to the first housing, and a motor assembly coupled to the barrier. The motor assembly includes a stator, a rotor configured to rotate the drum, a bearing housing, a rotary shaft disposed in the bearing housing, the rotary shaft having a first end coupled to the rotor and a second end coupled to the drum, and a first sealing part and a second sealing part that are disposed in the bearing housing and coupled to the rotary shaft.
