Abstract: An indoor unit for an air conditioner including a centrifugal fan. The centrifugal fan includes a main plate connectable to a rotation shaft of a motor, a plurality of blades, with one respective end to be bonded to the main plate and arrangeable at equal intervals from each other along a circumferential direction, a shroud, to be bonded to another respective end of the plurality of blades, to face the main plate, and a bell mouth arrangeable inside the shroud. An annular member arrangeable on an outer circumferential portion of the bell mouth with an inlet portion at the gap between the shroud and the bell mouth. The annular member including an annular flat plate portion spaced apart from and face the inlet portion, and a protrusion formed on an outer circumferential portion of a surface of the annular flat plate portion facing the shroud and being curved.

Abstract: A compressor and an air conditioner having the compressor, and a protective cover of a connecting terminal of the compressor is installed while spaced apart from a barrier of the connecting terminal. The protective cover is additionally provided with a noise preventing member. Vibration generated from the compressor is delivered to the protective cover via the barrier, but as the protective cover is provided to be spaced apart from the barrier, the vibration is delivered to the barrier through the noise preventing member. Thus, regardless of the state of vibration of the compressor, noise being generated by the protective cover is minimized.

Abstract: The centrifugal fan includes a base plate connected to a rotating shaft of a motor, a plurality of blades joined to a surface of the base plate, and a ring-shaped shroud joined to the plurality of blades to face the base plate. The blade is provided in such a way that a length of one end joint portion joined to the base plate is greater than a length of another end joint portion joined to the shroud, and with respect to a plane perpendicular to a rotation axis, an angle between a first straight line, which connects a leading edge position and a trailing edge position of the one end joint portion, and a straight line passing through a center point of the first straight line and a rotation center is less than an angle between a second straight line, which connects a leading edge position and a trailing edge position of the other end joint portion, and a straight line passing through a center point of the second straight line and the rotation center.
