Abstract: An indoor unit of an air conditioner includes a frame of the indoor unit; a heat exchanger mounted on the frame and having a refrigerant pipe in which a refrigerant flows; a hanger plate mounted on a rear surface of the frame and configured to fix the frame onto a wall surface; and a holder plate mounted on a lower portion of the frame and connecting the frame and the hanger plate. An end of the refrigerant pipe is placed in a space formed by the frame, the holder plate, and the hanger plate. The holder plate is movably connected on a lower portion of the frame, so the refrigerant pipe is accessible to a user to perform an operation of connecting or separating the refrigerant pipe to or from a connection pipe connected to an outdoor unit without rotating the frame.

Abstract: An indoor unit of an air conditioner having an improved frame structure in which a refrigerant pipe that connects an outdoor unit and the indoor unit can be easily connected. The indoor unit of the air conditioner includes: a frame; a heat exchanger mounted on the frame and having a refrigerant pipe in which a refrigerant flows; a hanger plate mounted on a rear surface of the frame and fixing the frame onto a wall surface; and a holder plate mounted on a lower portion of the frame, fixing the frame and the hanger plate, and supported by a fixing member of the wall surface. The holder plate selectively opens/closes the lower portion of the frame so that a pipe connection operation can be easily performed.

Abstract: An air conditioner includes an outdoor unit that includes a compressor configured to compress a refrigerant, a condenser configured to condense the compressed refrigerant, and a blowing fan configured to blow outdoor air into a room, an indoor unit that discharges air heat-exchanged with the refrigerant flowing-in from the outdoor unit to the room, and a connection piping that connects the outdoor unit and the indoor unit. Here, a plurality of protrusions may be formed at least one side of the blowing fan, and a convex portion and a concave portion may be formed on a surface of the blowing fan so that the surface of the blowing fan is indented.
