Abstract

A compressor cover includes a side cover that surrounds a side peripheral surface of a compressor and a top cover provided above the compressor to cover along with the side cover, the compressor. The top cover has a first slope that extends such that an outer peripheral portion of the top cover is located lower than a central portion of the top cover.

First claim

The invention claimed is:

1. A compressor cover comprising:
a side cover configured to surround a side peripheral surface of a compressor; and
a top cover provided above the compressor and configured to cover along with the side cover, the compressor,
wherein the top cover has a first slope that extends such that an outer peripheral side of the top cover is located lower than a central portion of the top cover,
wherein the top cover has a first hole portion configured to surround a refrigerant pipe extending upwards from the compressor and a first cut portion provided between the first hole portion and the outer peripheral side, the refrigerant pipe being located on a lower-pressure side of the compressor and allowing refrigerant to flow into the compressor, and the first slope is formed by causing both side portions of the first cut portion of the top cover to overlap each other,
wherein the outer peripheral side of the top cover is located outward of an outer peripheral portion of the side cover, and
wherein the top cover has a notch in a region that is different from a region including the first slope and that contacts a discharge pipe extending upwards from the compressor, the notch being formed to bare a part of an upper face of the compressor in a state where the top cover is attached to the compressor.

2. The compressor cover of claim 1 , wherein the first cut portion has a gap between the opposite sides on the outer peripheral side, while the both side portions of the first cut portion do not overlap each other.

3. The compressor cover of claim 1 , wherein in the top cover, an imaginary line inclined at a maximum tilt angle relative to a horizontal plane, which extends between the first hole portion of the first slope and the outer peripheral side, is located in an area of a lower one of the both side portions of the first cut portion when the both side portions of the first cut portion overlap each other, the area of the lower side portion including an area where a boundary between the overlapping side portions of the first cut portion is located.

4. The compressor cover of claim 1 , wherein the first slope is configured to guide liquid received by the top cover toward a drain exhaust passage of a bottom plate of a casing, on which the compressor is provided.

5. The compressor cover of claim 1 , wherein the top cover is formed of a hydrophobic or water-repellent material.

6. The compressor cover of claim 1 , wherein the top cover includes a pair of hook-and-loop fasteners on the both side portions of the first cut portion, the pair of hook-and-loop fasteners being used when the both side portions of the first cut portion are caused to overlap each other to form the first slope.

7. The compressor cover of claim 6 , wherein the pair of hook-and-loop fasteners are formed to extend along edge portions of the first cut portion and each have a length greater than or equal to half each of the lengths of the edge portions, the edge portions extending between the first hole portion ( 34 ) and the outer peripheral side.

8. The compressor cover of claim 1 ,
wherein the side cover has upper ends located at different levels, and
wherein in the top cover, the first slope is formed in such a manner as to be located on both the upper ends of the side cover that are located at the different levels.

9. The compressor cover of claim 8 ,
wherein the top cover includes two layers that are a rubber sheet and a felt sheet,
wherein the felt sheet serves as a lower layer underlying the rubber sheet, and
wherein the rubber sheet has an outer peripheral portion located outward of an outer peripheral portion of the felt sheet.

10. An outdoor unit of an air-conditioning-apparatus, comprising the compressor cover of claim 1 .

11. The air-conditioning apparatus comprising the outdoor unit of claim 10 .
