Abstract

A soundproof cover of a compressor for an air conditioner includes a sound-insulating material body portion ( 11 ) that is a rubber or thermoplastic-elastomer molded product with sound-insulating properties having a shape corresponding to an outer shape of a compressor body portion including a compressor leg portion positioned on a lower end side, having a folded portion ( 12 ) extending along a height direction of the compressor body portion and covering the compressor body portion by being folded through the folded portion ( 12 ), a sound-insulating material head portion ( 21 ) that is a rubber or thermoplastic-elastomer molded product with sound-insulating properties having a shape corresponding to an outer shape of a compressor head portion positioned on an upper end side of the compressor body portion and a sound absorbing material provided at least inside the sound-insulating material body portion ( 11 ).

First claim

The invention claimed is:

1. A soundproof cover of a compressor for an air conditioner comprising:
a sound-insulating material body portion, that is a rubber or thermoplastic-elastomer molded product with sound-insulating properties, having a shape corresponding to an outer shape of a compressor body portion and a compressor leg portion, wherein the sound-insulating material body portion has two members connected by a folded portion extending in a first direction, wherein the sound-insulating material body portion covers the compressor body portion by being folded through the folded portion;
a sound-insulating material head portion, that is a rubber or thermoplastic-elastomer molded product with sound-insulating properties, having a shape corresponding to an outer shape of a compressor head portion positioned on a first side of the compressor body portion; and
a sound absorbing material provided at least inside the sound-insulating material body portion, wherein
the folded portion includes a central portion having a first side extending in the first direction, having a second side extending in the first direction, and being disposed between and movably fixed to a first member of the two members and a second member of the two members,
the first member extends in the first direction on the first side of the central portion, and is movably fixed to the first side of the central portion,
the second member extends in the first direction on the second side of the central portion, and is movably fixed to the second side of the central portion,
the first side being opposite to the second side.

2. The soundproof cover of the compressor for the air conditioner according to claim 1 ,
wherein the sound-insulating material body portion and the sound-insulating material head portion are integrally molded.

3. The soundproof cover of the compressor for the air conditioner according to claim 1 , further comprising:
a sound-insulating material bottom portion having a shape for covering the compressor leg portion positioned on a second side of the compressor body portion.

4. The soundproof cover of the compressor for the air conditioner according to claim 3 ,
wherein the sound-insulating material body portion contacts a peripheral edge portion of the sound-insulating material bottom portion.

5. The soundproof cover of the compressor for the air conditioner according to claim 3 ,
wherein the sound-insulating material bottom portion is a reinforcing plate for reinforcing a bottom frame on which the compressor is installed.

6. The soundproof cover of the compressor for the air conditioner according to claim 5 ,
wherein the sound-insulating material body portion has a shape contacting the bottom frame or the reinforcing plate.

7. The soundproof cover of the compressor for the air conditioner according to claim 1 ,
wherein the folded portion has ribs provided in an approximately perpendicular direction with respect to the first direction.

8. The soundproof cover of the compressor for the air conditioner according to claim 1 ,
wherein the sound absorbing material is formed by arranging a nonwoven fabric sheet, a flame-retardant felt sheet and an aluminum sheet in order from the sound-insulating material body portion's side.

9. The soundproof cover of the compressor for the air conditioner according to claim 1 ,
wherein the sound-insulating material body portion has a sound-insulating material slit extending along a circumferential direction of the compressor.

10. The soundproof cover of the compressor for the air conditioner according to claim 9 ,
wherein the sound absorbing material has a sound-absorbing material slit extending along the circumferential direction of the compressor at a position different from the sound-insulating material slit in a height direction.

11. The soundproof cover of the compressor for the air conditioner according to claim 9 ,
wherein sound-insulating material body portion has a convex portion extending along the sound-insulating material slit on an upper part of the sound-insulating material slit.
