Abstract

Disclosed are: an accumulator fixing device for a compressor, the device being capable of minimizing the generation of vibration and noise; and an air-conditioning apparatus including the same. The disclosed accumulator fixing device comprises: fixing members fixedly provided to an outer side of a compressor; a first supporting member fixing a portion of the accumulator together with the fixing member while encompassing the circumference thereof; and a second supporting member fixing another portion of the accumulator together with the fixing member while encompassing the same, wherein the first supporting member and the second supporting member are arranged to be spaced from each other by a preset gap.

First claim

The invention claimed is:

1. An accumulator fixing device for a compressor, the accumulator fixing device comprising:
a first bracket and a second bracket that are fixed to an outer surface of the compressor;
a first strap configured to fix one portion of an accumulator while surrounding a circumference of the accumulator together with the first bracket; and
a second strap configured to fix another portion of the accumulator while surrounding the circumference at the other portion of the accumulator together with the second bracket,
wherein:
the first strap and the second strap are disposed to be spaced apart from each other by a predetermined interval,
the first bracket is fastened to opposite sides of the first strap,
the second bracket is fastened to opposite sides of the second strap and disposed to be spaced apart from the first bracket along a length direction of the compressor,
the compressor includes an inlet port into which a fluid is introduced from the accumulator,
the first strap is disposed above the second strap, and
a distance between the first bracket and the second bracket is 20% to 80% of a length between the first bracket and the inlet port.

2. The accumulator fixing device of claim 1 , wherein the first bracket and the second bracket are disposed on a virtual line disposed along the length direction of the compressor.

3. The accumulator fixing device of claim 1 , wherein:
the first bracket includes:
a first main fixing portion fixed onto an outer circumferential surface of the compressor; and
first auxiliary fixing portions each extending from opposite sides of the first main fixing portion and protruding toward the accumulator, and

the second bracket includes:
a second main fixing portion fixed onto the outer circumferential surface of the compressor; and
second auxiliary fixing portions each extending from opposite sides of the second main fixing portion and protruding toward the accumulator.

4. The accumulator fixing device of claim 3 , wherein:
the first auxiliary fixing portions include:
a first auxiliary vertical fixing portion which is vertically connected to the first main fixing portion; and
a first auxiliary horizontal fixing portion which is connected to the first auxiliary vertical fixing portion and is in contact with the outer circumferential surface of the accumulator, and

the second auxiliary fixing portions include:
a second auxiliary vertical fixing portion which is vertically connected to the second main fixing portion; and
a second auxiliary horizontal fixing portion which is connected to the second auxiliary vertical fixing portion and is in contact with the outer circumferential surface of the accumulator.

5. The accumulator fixing device of claim 4 , wherein:
one of the first auxiliary fixing portions are disposed at one side of the first main fixing portion and includes a first protruding portion connected to the first auxiliary horizontal fixing portion and protruding toward the compressor,
another of the first auxiliary fixing portions are disposed at another side of the first main fixing portion and includes a first fastening portion protruding toward the compressor and connected to the first auxiliary horizontal fixing portion and having a first fastening hole penetrating through the first fastening portion along a thickness direction of the first fastening portion,
one of the second auxiliary fixing portions disposed at one side of the second bracket and includes a second protruding portion connected to the second auxiliary horizontal fixing portion and protruding toward the compressor, and
another of the second auxiliary fixing portions disposed at another side of the second bracket and includes a second fastening portion protruding toward the compressor and connected to the second auxiliary horizontal fixing portion and having a second fastening hole penetrating through the second fastening portion along a thickness direction of the second fastening portion.

6. The accumulator fixing device of claim 5 , wherein:
a first catching hole protruding toward the accumulator and fixed to the first protruding portion is formed at one side of the first strap, and another side of the first strap includes a first coupling portion bent to opposite to the first fastening portion and having a first coupling hole corresponding to the first fastening hole, and
a second catching hole protruding toward the accumulator and fixed to the second protruding portion is formed at one side of the second strap, and another side of the second strap includes a second coupling portion bent to opposite to the second fastening portion and having a second coupling hole corresponding to the second fastening hole.

7. The accumulator fixing device of claim 4 , wherein:
the first auxiliary horizontal fixing portion includes first protruding portions each connected to one side and another side of the first auxiliary horizontal fixing portion and protruding toward the compressor,
the second auxiliary horizontal fixing portion includes second protruding portions each connected to one side and another side of the second auxiliary horizontal fixing portion and protruding toward the compressor,
first catching holes each protruding toward the accumulator and each fixed to the first protruding portions are formed in one side and another side of the first strap, and
second catching holes each protruding toward the accumulator and each fixed to the second protruding portions are formed in one side and another side of the second strap.

8. The accumulator fixing device of claim 3 , further comprising an anti-vibration member configured to have a first upper fixing portion inserted and fixed into a first installing hole penetrating through the first auxiliary fixing portions along a thickness direction of the first auxiliary fixing portions, and a first lower fixing portion which is connected to the first upper fixing portion and is closely in contact with the outer circumferential surface of the accumulator.

9. The accumulator fixing device of claim 1 , wherein a width of the first bracket is 40% or less of a distance between the first bracket and the inlet port.

10. The accumulator fixing device of claim 1 , wherein thicknesses of the first strap and the second strap are 1 to 5T.

11. The accumulator fixing device of claim 1 , wherein:
the first bracket is fastened to opposite sides of the first strap;
the second bracket is spaced apart from the first bracket and fastened to opposite sides of the second strap; and
connection members each connected between the first bracket and the second bracket and fixed onto an outer circumferential surface of the compressor.

12. An air-conditioning apparatus comprising:
a compressor;
a condenser configured to condense a refrigerant introduced from the compressor;
an evaporator configured to cool surrounding air using evaporated latent heat of the refrigerant introduced from the condenser;
an accumulator configured to provide the refrigerant of a vapor state to the compressor; and
an accumulator fixing device for the compressor configured to fix the accumulator and the compressor to each other,
wherein the accumulator fixing device for the compressor includes:
a first bracket and a second bracket that are fixed to an outer surface of the compressor,
a first strap configured to fix one portion of the accumulator while surrounding a circumference of the accumulator together with the first bracket, and
a second strap configured to fix another portion of the accumulator while surrounding the circumference at the other portion of the accumulator together with the second bracket, an
