Abstract

Disclosed is an air conditioner with a compressor fixation structure having improved product reliability due to strengthened hardness of a boss. The air conditioner includes a compressor for compressing a refrigerant, a base for supporting the compressor, a compressor support coupled to the base to support the compressor; at least one boss protruding from the base, a vibration absorption member for absorbing vibration generated by the compressor, and a fastening member, wherein the fastening member is inserted into the boss and the vibration absorption member, and at least a portion of the fastening member protrudes below a bottom surface of the base.

First claim

The invention claimed is:

1. An air conditioner comprising:
a compressor configured to compress a refrigerant;
a base configured to support the compressor;
a compressor support coupled to the base and configured to support the compressor;
at least one boss configured to protrude from the base and including an insertion hole with an inclined inner surface;
a vibration absorption member disposed between the compressor support and the boss, configured to absorb vibrations generated from the compressor, and having a height greater than a height of the boss; and
a fastening member configured to couple the boss, the vibration absorption member, and the compressor support, the fastening member including:
a head,
a body protruding from a bottom surface of the head, wherein a lower end of the body is supported by the boss, and
a fastening portion protruding from a bottom surface of the body,

wherein the boss protrudes from the base into a hole of the vibration absorption member,
wherein the fastening member is inserted into the insertion hole of the boss and the vibration absorption member, and at least a part of the fastening member protrudes through the boss and downward from a lower surface of the base at least the part of the fastening member including an inclined portion that is seated on the inclined inner surface of the insertion hole in the at least one boss,
wherein the fastening portion has a smaller diameter than the body, and the fastening member further includes a guide provided between the fastening portion and the body,
wherein the guide is provided on an upper end of the fastening portion to guide insertion of the fastening member into the boss, and the guide includes the inclined portion seated inside the boss on the inclined inner surface of the boss,
wherein the inclined portion has a diameter that gradually decreases in a direction moving away from the head, and
the inclined inner surface has a diameter that gradually decreases in a same direction as the inclined portion and corresponds to the diameter of the inclined portion.

2. The air conditioner of claim 1 , wherein, in the vibration absorption member, a length in a first direction, in which the fastening member is inserted into the vibration absorption member, is formed to be greater than a length by which the boss protrudes from an upper surface of the base.

3. The air conditioner of claim 1 , wherein the body is disposed to be spaced apart from the vibration absorption member.

4. The air conditioner of claim 1 , wherein, in the fastening portion, a screw thread is formed on an outer circumferential surface of the fastening portion so that the fastening member is screw-coupled to the boss.

5. The air conditioner of claim 1 , wherein an inner diameter of the boss varies to correspond to a diameter of the guide.

6. The air conditioner of claim 1 , wherein the fastening member further includes a washer provided on an upper portion of the body to prevent separation of the vibration absorption member.

7. The air conditioner of claim 6 , wherein the washer is disposed to be spaced apart from the vibration absorption member.

8. The air conditioner of claim 6 , wherein the washer is provided separately from the fastening member.

9. The air conditioner of claim 6 , wherein the head is provided on an upper end of the washer.

10. The air conditioner of claim 9 , wherein the head is provided in a shape to which a rotational force is applied.

11. The air conditioner of claim 1 , wherein the vibration absorption member is formed of an elastic material.

12. An air conditioner comprising:
a compressor configured to compress a refrigerant;
a base configured to support the compressor;
a compressor support coupled to the base and configured to support the compressor;
at least one boss configured to protrude from the base and including an insertion hole with an inclined inner surface;
a vibration absorption member disposed between the compressor support and the boss, configured to absorb vibrations generated from the compressor, and having a height greater than a height of the boss; and
a fastening member configured to couple the boss, the vibration absorption member, and the compressor support, the fastening member including:
a head,
a body protruding from a bottom surface of the head, wherein the body is supported by the boss, and
a fastening portion protruding from a bottom surface of the body,

wherein the boss protrudes from the base into a hole of the vibration absorption member,
wherein the fastening member is inserted into the insertion hole of the boss and the vibration absorption member, and at least a part of the fastening member protrudes through the boss and downward from a lower surface of the base at least the part of the fastening member including an inclined portion that is seated on the inclined inner surface of the insertion hole in the at least one boss,
wherein the base is integrally formed with the boss,
wherein the fastening portion has a smaller diameter than the body, and the fastening member further includes a guide provided between the fastening portion and the body,
wherein the guide is provided on an upper end of the fastening portion to guide insertion of the fastening member into the boss, and includes the inclined portion seated inside the boss on the inclined inner surface of the boss,
wherein the inclined portion has a diameter that gradually decreases in a direction moving away from the head, and
the inclined inner surface has a diameter that gradually decreases in a same direction as the inclined portion and corresponds to the diameter of the inclined portion.

13. The air conditioner of claim 12 , wherein the body is disposed to be spaced apart from the vibration absorption member.

14. The air conditioner of claim 12 , wherein, in the fastening portion, a screw thread is formed on an outer circumferential surface of the fastening portion so that the fastening member is screw-coupled to the boss.
