Abstract: An indoor unit of an air-conditioning apparatus includes a fan, a heat exchanger, and a drain receiver. The interior of the housing is partitioned into a first space and a second space in an axial direction of the rotating shaft of the fan. In the first space, a first opening is provided to allow air to flow out toward a region located outward of the fan in the first space in a radial direction of the fan. In the second space, no opening is provided and a region located outward of the fan in the second space is closed in the radial direction of the fan. In at least part of a space between the fan in the first space and the heat exchanger, a first water receiving device is provided at a higher position than the drain receiver.

Abstract: An impeller includes a boss provided on a rotation axis and a blade provided on an outer circumferential side of the boss. The blade has a radially middle portion that is located midway between an outer circumferential edge and an inner circumferential edge in a radial direction of the blade from the rotation axis. A span-direction section of part of the blade that adjoins the leading edge is shaped such that part of a suction side of the blade that is located in an area between the radially middle portion and the outer circumferential edge is concave, and a span-direction section of part of the blade that adjoins the trailing edge is shaped such that part of the suction side of the blade that is located in the area between the radially middle portion and the outer circumferential edge is convex.

Abstract: This rotary electric machine includes: an electric motor; a power supply unit including a heat-dissipation member, a power module, and a cover covering the heat-dissipation member and the power module; and a coolant path. A connection portion connecting the electric motor and the power supply unit is provided between the housing and the power supply unit. A cylindrical portion of the cover extends toward the one side in the axial direction and covers the connection portion from the radially outer side. The coolant path is provided at one or both of the heat-dissipation member and an area between the heat-dissipation member and the housing. The coolant path overlaps the power module as seen in the axial direction. The cylindrical portion of the cover has an opening through which a coolant passes, at a circumferential-direction position different from a circumferential-direction position on the radially outer side of the connection portion.
