Abstract: An outdoor unit of an air conditioner includes a housing including an outlet, a fan disposed inside the housing, and a guide guiding air flowing by the fan, wherein the guide includes an inflow portion provided to guide air introduced into the housing to the fan and a diffuser extending from the inflow portion to guide air passing through the fan to the outlet. The inflow portion includes a duct connected to the diffuser, a bell mouth disposed on an upstream side further than the duct and configured such that a width of an inlet end of the bell mouth is wider than a width of an outlet end of the bell mouth, and a guide vane formed on the bell mouth and configured to guide air introduced into the fan.

Abstract: In an air-conditioning system, a gaseous refrigerant remaining in a reservoir can be discharged from the reservoir even when a cooling operation has started and the reservoir is being filled with a liquid refrigerant. Therefore, the reservoir can be filled with the liquid refrigerant at a faster speed.

Abstract: Disclosed are provided indoor unit of an air conditioner. A present invention is to provide an indoor unit of an air conditioner having an improved structure for preventing vibrations and noise of a blade due to vibrations of a motor when the blade rotates, and a blade unit applied to the indoor unit. The indoor unit of the air conditioner includes a main body including an outlet, and a blade unit configured to adjust a direction in which air discharged from the outlet is discharged, wherein the blade unit comprises, a blade coupled with the main body to be rotatable in the outlet, a motor including a rotation transfer member, and configured to generate a rotatory force that is transferred to the blade; and a buffer member made of a material having a restoring force, coupled with the blade at one end, and surrounding a part of the rotation transfer member.

Abstract: An outdoor unit of an air conditioner includes a cabinet including a first plate and a second plate, a blower disposed inside the cabinet, and a blower cover covering the blower and an upper side of the cabinet. The first plate includes a contact area in contact with the blower cover in an outward direction of the cabinet, and the second plate includes a first non-contact area that is not in contact with the blower cover in the outward direction of the cabinet. The blower cover is disposed on one of four plates of the cabinet to reduce the noise generated due to the vibration of the cabinet by reducing the vibration transmitted from the blower cover to the cabinet.
