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.

Washing machine

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.

The present disclosure provides an electric compressor comprising a main housing, a motor part disposed in the main housing and comprising a stator comprising a rotor accommodating portion and a rotor rotatably disposed in the rotor accommodating portion, a compression part rotatably connected to the motor part, and an inverter part electrically connected to the motor part. The motor part is disposed in a motor room formed inside the main housing, the stator comprises a plurality of insulating protrusions protruding from an outer circumferential surface of the stator, and the plurality of insulating protrusions is configured to be brought into contact with an inner circumferential surface of the motor room.

Electric compressor with improved insulation performance

A motor-operated compressor includes a casing having an inner space in which a driving motor, an orbiting scroll and a fixed scroll are accommodated, and a controller provided outside the casing. The casing includes an intake hole formed at a side adjacent to the controller and an exhaust hole formed at a side adjacent to the fixed scroll on the basis of the driving motor. The casing includes a communication passage formed between the casing and a stator of the driving motor, such that a refrigerant introduced into the inner space through the intake hole is introduced into the suction chamber through the driving motor. A back pressure space supporting the orbiting scroll is sealed by oil. The stator has teeth on its inner circumferential surface and protrusions on its outer circumferential surface, each protrusion being located within a width range of each tooth.
