Abstract

A rotary compressor including an attachment leg which is fixed to a bottom portion of a compressor housing and includes three locking holes which are locking holes to which three corresponding elastic supporting members, which support the compressor housing, are locked and which are disposed to be separated from each other in a circumferential direction on an outside in a radial direction of the compressor housing, in which, of the three locking holes, a distance of a first locking hole which is disposed closest to an accumulator from a housing center, is greater than a distance of each of the other two locking holes from the housing center.

First claim

What is claimed is:

1. A rotary compressor comprising:
a sealed vertically-placed cylindrical compressor housing which is provided with a discharge unit of a refrigerant on a top portion and which is provided with an inlet unit of the refrigerant on a bottom portion;
a rotary-type compressor unit which is disposed on the bottom portion of the compressor housing, compresses the refrigerant which is sucked in from the inlet portion, and discharges the refrigerant from the discharge unit;
a motor which is disposed on the top portion of the compressor housing and which drives the rotary-type compressor unit;
a vertically-placed cylindrical accumulator which is fixed to a side portion of the compressor housing and which is connected to the inlet portion; and
an attachment leg having a triangular plate shape which is fixed to the bottom portion of the compressor housing and includes three locking holes which are locking holes to which three corresponding elastic supporting members, which support the compressor housing, are locked and which are disposed at each corner of the triangular plate shape to be separated from each other in a circumferential direction on an outside in a radial direction of the compressor housing,
wherein, of the three locking holes, a distance of a first locking hole which is disposed closest to the accumulator from a housing center, is greater than a distance of each of the other two locking holes from the housing center, and
a pitch angle around the housing center between the first locking hole and a second locking hole which interposes the accumulator between the first locking hole and the second locking hole, is smaller than a pitch angle around the housing center between the first locking hole and a third locking hole, and a pitch angle around the housing center between the second locking hole and the third locking hole.

2. The rotary compressor according to claim 1 , wherein the first locking hole is disposed in a position no closer to an outside in the radial direction than the accumulator, and the first locking hole is disposed inward from a periphery of the accumulator disposed radially outward of the compressor.

3. The rotary compressor according to claim 1 , wherein the first locking hole is disposed in a position which does not overlap the accumulator as viewed from above.

4. The rotary compressor according to claim 1 , wherein a center of the accumulator is disposed outwardly of the attachment leg when viewed from a vertical direction of the compressor housing.
