An outdoor unit for an air-conditioning apparatus includes a heat exchanger; a bottom plate; and a separation member configured to separate the bottom plate and the heat exchanger. The bottom plate includes a drainage passage that protrudes downward; and one or more drainage holes each formed to protrude downward from the drainage passage. The drainage passage includes a drainage surface inclined downward toward the one drain hole having a width larger than a width of the heat exchanger. The separation member is formed of a metal electrically less noble than a member forming the heat exchanger, or a resin member. The separation member is provided in the drainage passage and shaped to prevent closing of the drainage passage, in which a height to a surface on which the heat exchanger is placed is larger than a height to an upper surface of the drainage passage.

An air conditioning appliance includes a housing, a drain pan positioned below the housing, and a plenum which is attached to the housing and to the drain pan. The drain pan includes an upper surface in contact with the housing and a socket configured to receive a leg. The housing of the air conditioning appliance rests on the upper surface of the drain pan, such that the drain pan defines a platform which structurally supports the housing of the air conditioning appliance.

An outdoor unit of an air-conditioning apparatus includes: a housing; and a partition plate, a device accommodated in a machine chamber, a fan accommodated in a fan chamber, the partition plate having a wiring passage, wherein the outdoor unit includes a water receiving part provided to the machine chamber, the water receiving part having a box shape, a side wall portion of the water receiving part has a first opening port, and an upper surface portion of the water receiving part has a second opening port, the water receiving part is attached to the partition plate such that an edge of the first opening port is in contact with the partition plate, a gap, through which water discharged by the water receiving part passes, is formed between a bottom portion of the water receiving part and the partition plate, the bottom portion being inclined toward the gap.
