Outdoor unit, and refrigeration cycle device

An outdoor unit of a refrigeration cycle device comprising:

• a housing having a first room and a second room that are partitioned from one another by a partition;
• a heat exchanger disposed on an inside of the first room;
• a blower that is disposed on the inside of the first room, and
• controlling circuitry that is disposed on an inside of the second room, wherein
• on a bottom of the housing
• a drain water hole that is formed on a bottom of the first room;
• a drain water flow path portion that is connected to the drain water hole, and that is formed so as to straddle between the bottom of the first room and the bottom of the second room, and
• a pair of supports that support the partition from a bottom side in a vertical direction,
• are formed on a bottom of the housing,
• the drain water flow path portion has an inbetween flow path portion that is located between the pair of supports,
• the partition has a protrusion that faces a bottom surface of the inbetween flow path portion via a gap on a top side in the vertical direction,
• a step portion is formed on a bottom surface of the inbetween flow path portion so as to have a side that is farther from the drain water hole be higher than a side that is closer to the drain water hole, in an extension direction in which the inbetween flow path portion extends in, as seen from the top side in the vertical direction, and
• a flow path width of the inbetween flow path portion is smaller than
• a maximum flow path width that is connected to a downstream side of the inbetween flow path portion, out of the drain water flow path portion, and
• a flow path width that is connected to an upstream side of the inbetween flow path portion, out of the drain water flow path portion.
