Abstract: A food waste disposer including a housing; a grinding device inside the housing to grind food waste; an exhaust fan inside the housing to form an air flow; an exhaust pipe connected to the exhaust fan to form an exhaust flow path along which air from the grinding device flows via the air flow formed by the exhaust fan; a filter assembly to adsorb contaminants from the air flowing along the exhaust flow path; a branch pipe branching from the exhaust pipe between the grinding device and the exhaust fan to form a connection flow path communicating with the exhaust flow path; and a sterilization device connected to the branch pipe to selectively open and close the connection flow path, and, with the connection flow path being open, generate and supply plasma to the exhaust pipe through the connection flow path via an intake airflow formed by the exhaust fan.

Abstract: A scroll compressor including a fixed scroll including a wrap accommodation portion having an inner space extending inside the wrap accommodation portion, a thrust surface around the inner space, a fixed wrap in the inner space, and an oil groove on the thrust surface; an orbiting scroll to rotate with respect to the fixed scroll, and including a mirror plate, an orbiting wrap extending from the mirror plate to engage with the fixed wrap, and at least one oil supply groove on the mirror plate facing the thrust surface of the fixed scroll; and a driving motor to rotate the orbiting scroll. When the orbiting scroll rotates, the at least one oil supply groove of the orbiting scroll moves from a first position to receive oil from the oil groove, to a second position to supply the oil to the inner space of the wrap accommodation portion.
