Abstract
Official abstract text for this publication.
A rotary compressor includes a compressor housing that is provided with a refrigerant discharge portion and refrigerant suction portions, a compression unit that is arranged in the compressor housing and compresses a refrigerant, sucked from the suction portions, and discharges it from the discharge portion, a motor that is arranged in the compressor housing and drives the compression unit, an accumulator that is connected to the suction portions, and a mounting member that secures the accumulator to the compressor housing. The compressor housing and an accumulator container of the accumulator are made of a metal material. The mounting member is at least partially made of a resin material and has a first joint portion, which is joined to an outer peripheral surface of the compressor housing.
First claim
Opening claim text (preview).
The invention claimed is: 1. A rotary compressor comprising: a compressor housing that is provided with a refrigerant discharge portion and a refrigerant suction portion; a compression unit that is arranged inside the compressor housing and configured to compress a refrigerant, sucked from the suction portion, and discharge the refrigerant from the discharge portion; a motor that is arranged inside the compressor housing and configured to drive the compression unit; an accumulator that is connected to the suction portion; and a mounting member that is configured to secure the accumulator to the compressor housing, wherein the compressor housing and an accumulator container of the accumulator are made of a metal material, and the mounting member is made only of a resin material and has a first joint portion, which is bonded to an outer peripheral surface of the compressor housing. 2. The rotary compressor according to claim 1 , wherein the mounting member has a second joint portion, which is bonded to the outer peripheral surface of the accumulator container. 3. The rotary compressor according to claim 2 , wherein the mounting member has a set of mounting pieces, and each of the set of mounting pieces is provided with the first joint portion at one end portion, and is provided with a second joint portion at another end portion. 4. A rotary compressor comprising: a compressor housing that is provided with a refrigerant discharge portion and a refrigerant suction portion; a compression unit that is arranged inside the compressor housing and configured to compress a refrigerant, sucked from the suction portion, and discharge the refrigerant from the discharge portion; a motor that is arranged inside the compressor housing and configured to drive the compression unit; an accumulator that is connected to the suction portion; and a mounting member that is configured to secure the accumulator to the compressor housing, wherein the compressor housing and an accumulator container of the accumulator are made of a metal material, the mounting member has a first mounting piece made of a metal material, and a second mounting piece made of a resin material, and the first mounting piece and the second mounting piece are integrally molded. 5. The rotary compressor according to claim 4 , wherein the first mounting piece has a first joint portion, and the second mounting piece has a second joint portion, which is joined to an outer peripheral surface of the accumulator container. 6. The rotary compressor according to claim 1 , wherein the resin material is a thermoplastic resin material and has a functional group, which is reactive with a metal material.
