An indoor unit for an air-conditioning apparatus includes a heat exchanger and an air-blowing device disposed upstream of the heat exchanger. The air-blowing device of the indoor unit includes a casing, a bellmouth disposed to an air inlet of the casing, a fan of one of an axial-flow type and a diagonal-flow type disposed within the bellmouth, a motor for rotating the fan, a motor base holding the motor, and a motor stay connecting the motor base to the bellmouth. The fan includes blades. The motor stay includes rod-shaped members. The motor stay of the air-blowing device is configured such that, in plan view, a downstream edge of each blade of the fan intersects any of the rod-shaped members of the motor stay irrespective of the angle of rotation of the fan.

A heat exchanger includes a plurality of bent parts where a direction of slope of the heat exchanger changes from an upward direction to a downward direction or from a downward direction to an upward direction. The plurality of bent parts is provided on each of a side of an air inlet and a side of an air outlet. The heat exchanger is provided such that all of the plurality of bent parts is visible when the heat exchanger is seen from a front side of a casing. Drain pans are provided below each of the plurality of bent parts that are on the side of the air outlet.
摘要:
In an indoor unit for an air-conditioning apparatus, a downstream edge of each of the blades of the fan of an air-blowing device, when viewed in plan view, intersects any of the members of a motor stay of the air-blowing device irrespective of an angle of rotation of the fan. The motor stays are connected to the mounting portions of a bellmouth in which the fan is disposed, wherein the mounting portions protrude downward from a downstream outlet end of the bellmouth and each include side surfaces, of which at least a first side surface opposing a pressure surface of each of the blades of the fan is at an angle relative to a rotation axis of the fan.

[Object] An object is to obtain an indoor unit of an air-conditioning apparatus, the indoor unit including a propeller fan in the vicinity of an air inlet, the indoor unit being capable of ensuring the strength of a casing and suppressing degradation of performance by reducing an increase in draft resistance of sucked-in air.[Solution] In an indoor unit 1 of an air-conditioning apparatus, at least one propeller fan 10 having a fan guard 50 is disposed downstream of an air inlet 130 formed at the top of the indoor unit 1. The air inlet 130 is provided with bars 140. Each of the bars 140 is located, in a vertical cross-section perpendicular to the longitudinal direction of the bar 140, within a virtual cylinder 13 obtained by projecting a boss 11 of the propeller fan 10 in the direction of the rotation axis of the propeller fan 10.
