Abstract

An outdoor unit for an air-conditioning apparatus includes a casing having an air inlet through which air enters the casing, an air-sending device disposed in the casing and configured to create a flow of air passing through the air inlet, a heat exchanger disposed between the casing and the air-sending device and exposed through the air inlet and including a plurality of fins spaced apart from each other, and a partition disposed in the casing and dividing a space in the casing into an air-sending device chamber containing the heat exchanger and the air-sending device and a machine chamber containing a compressor. The plurality of fins include an end fin group located at an end remote from the partition. The casing includes a wall having at least one vent that faces the end fin group and that is located along a side edge part defining an edge of the air inlet.

First claim

The invention claimed is:

1. An outdoor unit for an air-conditioning apparatus, the outdoor unit comprising:
a casing having at least one air inlet through which air enters the casing;
an air-sending device disposed in the casing and configured to create a flow of air passing through the at least one air inlet;
a heat exchanger disposed between the casing and the air-sending device and exposed through the at least one air inlet, the heat exchanger including a plurality of fins spaced apart from each other; and
a partition disposed in the casing and dividing a space in the casing into an air-sending device chamber containing the heat exchanger and the air-sending device and a machine chamber containing a compressor,
a plurality of fins including an end fin group located at an end of the heat exchanger remote from the partition,
the casing including a wall having at least one vent that faces the end fin group and that is located along a side edge part defining an edge of the at least one air inlet,
the heat exchanger being I-shaped when the heat exchanger is viewed in a direction perpendicular to a base on which the heat exchanger and the air-sending device are arranged,
the wall having the at least one vent being opposite a front wall having an air outlet through which air subjected to heat exchange is blown, and constituting a rear wall of the air-sending device chamber.

2. The outdoor unit for an air-conditioning apparatus of claim 1 , wherein the end fin group includes an outermost fin located at an extremity remote from the partition,
wherein the wall has an overlapping region that is a wall part located between the side edge part and the outermost fin when the wall is viewed in a direction perpendicular to the wall, and
wherein at least part of the at least one vent is located in the overlapping region.

3. The outdoor unit for an air-conditioning apparatus of claim 2 , wherein the outermost fin is located in the at least one vent when the at least one vent is viewed in the direction perpendicular to the wall.

4. The outdoor unit for an air-conditioning apparatus of claim 2 , wherein only the plurality of fins are arranged in the at least one vent when the at least one vent is viewed in the direction perpendicular to the wall.

5. The outdoor unit for an air-conditioning apparatus of claim 1 , wherein the side edge part is bent toward the plurality of fins.

6. The outdoor unit for an air-conditioning apparatus of claim 1 , wherein the at least one vent has a circular shape.

7. The outdoor unit for an air-conditioning apparatus of claim 1 , wherein the at least one vent has a corner-rounded rectangular shape.

8. The outdoor unit for an air-conditioning apparatus of claim 1 , wherein the at least one vent has an oblong shape.

9. The outdoor unit for an air-conditioning apparatus of claim 1 , wherein the side edge part extends in the direction perpendicular to the base on which the heat exchanger and the air-sending device are arranged.

10. The outdoor unit for an air-conditioning apparatus of claim 9 , wherein
the vent is located between the side edge part and a side wall of the casing that is closest to the side edge part, the side wall of the casing connecting the front wall and the wall having the at least one vent.

11. The outdoor unit for an air-conditioning apparatus of claim 1 , wherein
the vent is located between the side edge part and a side wall of the casing that is closest to the side edge part, the side wall of the casing connecting the front wall and the wall having the at least one vent.
