Abstract

An outdoor unit of an air-conditioning apparatus includes: a terminal unit that is provided on an outer peripheral surface of a compressor, and electrically connects components provided in the compressor and outside the compressor; a side soundproof cover that covers the outer peripheral surface of the compressor except for the terminal unit; and a terminal cover that covers the terminal unit exposed from the side soundproof cover to the outside of the side soundproof cover, and soundproofs the terminal unit. The terminal cover is attached to the side soundproof cover such that the state of the terminal cover can be changed between a state in which the terminal cover covers the terminal unit and a state in which the terminal cover does not cover the terminal unit.

First claim

The invention claimed is:

1. An outdoor unit of an air-conditioning apparatus, comprising:
a terminal provided on an outer peripheral surface of a compressor, and configured to electrically connect components provided in the compressor and outside the compressor;
a side soundproof cover configured to cover the outer peripheral surface of the compressor except for the terminal; and
a terminal cover configured to cover the terminal exposed from the side soundproof cover to the outside of the side soundproof cover and to soundproof the terminal,
wherein at least a part of the terminal cover is detachably attached to the side soundproof cover so that the terminal cover is configured to be changed between a state in which the terminal cover covers the terminal and a state in which the terminal cover does not cover the terminal,
wherein the terminal cover and the side soundproof cover include respective fasteners configured to be engaged with each other,
wherein the terminal cover includes a sound insulating sheet configured to prevent passage of sound, a sound absorbing sheet configured to absorb sound, and sewn portions that are formed to unite the sound insulating sheet, the sound absorbing sheet, and the fasteners of the terminal cover, and
wherein each of the sound insulating sheet and the sound absorbing sheet of the terminal cover is a deformable sheet and has a rectangular shape when in an unfolded state before attachment of the terminal cover to the side soundproof cover.

2. The outdoor unit of an air-conditioning apparatus of claim 1 , wherein
the sound insulating sheet and the sound absorbing sheet of the terminal cover are put on each other and united,
the sound insulating sheet is formed of a hydrophobic or water-repellent material, and
the terminal cover is attached to the side soundproof cover such that the sound insulating sheet is located on an outer side of the terminal cover.

3. The outdoor unit of an air-conditioning apparatus of claim 1 , wherein the sound insulating sheet has a notch that is formed at a center portion of the sound insulating member in a circumferential direction of the compressor, and the notch is configured to serve as a mark with reference to which the terminal cover is attached to the side soundproof cover at a proper position where the terminal cover covers the terminal.

4. The outdoor unit of an air-conditioning apparatus of claim 1 , wherein the terminal cover is detachably attached to the side soundproof cover by the fastener of the terminal cover so that the terminal cover is entirely removable from the side soundproof cover.

5. The outdoor unit of an air-conditioning apparatus of claim 1 , wherein the fasteners of the terminal cover and the side soundproof cover include a hook and loop fastener.

6. The outdoor unit of an air-conditioning apparatus of claim 1 , wherein
the sound insulating sheet includes a plurality of pairs of notches formed in outer edges of the sound insulating sheet, the notches serving as marks with reference to which the sewn portions are formed, and
lines each connecting the notches of an associated one of the plurality of pairs are provided as marks for sewing.

7. The outdoor unit of an air-conditioning apparatus of claim 1 , wherein the terminal cover is fixed to the side soundproof cover such that a state of the terminal cover is allowed to be changed between a state in which the terminal cover covers the terminal and a state in which the terminal cover does not cover the terminal.

8. The outdoor unit of an air-conditioning apparatus of claim 7 , wherein
one of two opposing edges of the terminal cover is fixed to the side soundproof cover and an other of the two opposing edges is not fixed to the side soundproof cover, and
the fastener of the terminal cover is provided at the other of the two opposing edges.
