Abstract

A compressor and an air conditioner having the compressor, and a protective cover of a connecting terminal of the compressor is installed while spaced apart from a barrier of the connecting terminal. The protective cover is additionally provided with a noise preventing member. Vibration generated from the compressor is delivered to the protective cover via the barrier, but as the protective cover is provided to be spaced apart from the barrier, the vibration is delivered to the barrier through the noise preventing member. Thus, regardless of the state of vibration of the compressor, noise being generated by the protective cover is minimized.

First claim

What is claimed is:

1. A compressor, comprising: a case; a connecting terminal protruded to an outside of the case; a barrier surrounding the connecting terminal; and a protective cover mounted at the barrier, wherein the protective cover is mounted while spaced apart from a front end surface and a side surface of the barrier, the protective cover comprises a step formed between an open end portion and an inner surface of the protective cover, and at least one noise preventing member, the at least one noise preventing member includes a barrier front end facing portion disposed along the step so as to face the front end surface of the barrier, and a barrier side surface facing portion formed with the barrier front end facing portion and disposed along a side surface of the protective cover so as to face the side surface of the barrier, and when the protective cover is mounted at the barrier, the barrier is not in contact with the barrier front end facing portion or the barrier side surface facing portion.

2. The compressor of claim 1 , wherein:
the at least one noise preventing member is provided with one unit thereof installed at an upper portion of the protective cover, and with two units thereof installed while being spaced apart from each other at a lower portion of the protective cover.

3. The compressor of claim 1 , wherein:
the protective cover further comprises at least one installation member extended from the open end portion of the protective cover so as to be mounted at the barrier.

4. The compressor of claim 3 , wherein:
the at least one noise preventing member is provided at a side of the protective cover at which the installation member is positioned.

5. An air conditioner having a compressor, the compressor comprising:
a case;
a connecting terminal protruded to an outside of the case;
a barrier surrounding the connecting terminal; and
a protective cover mounted at the barrier,
wherein the protective cover is mounted while spaced apart from the barrier such that delivery of vibration being generated at the compressor is reduced, and
the protective cover comprises
a step formed between an open end portion and an inner surface of the protective cover, and
at least one noise preventing member including a barrier front end facing portion disposed along the step so as to face a front end surface of the barrier, and a barrier side surface facing portion formed with the barrier front end facing portion and disposed along a side surface of the protective cover so as to face a side surface of the barrier,
wherein when the protective cover is mounted at the barrier, the barrier is not in contact with the barrier front end facing portion or the barrier side surface facing portion.

6. The air conditioner of claim 5 , wherein:
the at least one noise preventing member is provided such that the vibration of the compressor is delivered to the protective cover through the at least one noise preventing member.

7. The air conditioner of claim 5 , wherein:
the protective cover further comprises at least one installation member provided at one end portion of the protective cover as to be mounted at the barrier.

8. The air conditioner of claim 7 , wherein:
the at least one noise preventing member is provided at a side of the protective cover at which the installation member is positioned.

9. A compressor, comprising: a case; a connecting terminal protruded to an outside of the case; a barrier surrounding the connecting terminal; and a protective cover mounted at the barrier, the protective cover having the shape of a casing having an open end portion, an inner surface and a side surface, the protective cover being configured to be mounted to cover the barrier while facing a front end surface of the barrier, wherein the protective cover comprises an installation member formed at the open end portion to attach the protective cover to the barrier, a step formed at a position between the open end portion and the inner surface, and at least one noise preventing member installed so as to face the front end surface and a side surface of the barrier, and wherein the at least one noise preventing member includes a barrier front end facing portion disposed along the step so as to face the front end surface of the barrier, and a barrier side surface facing portion formed with the barrier front end facing portion and disposed along the side surface of the protective cover so as to face the side surface of the barrier, and when the protective cover is mounted at the barrier, the barrier is not in contact with the barrier front end facing portion or the barrier side surface facing portion.

10. The compressor of claim 9 , wherein the thickness of the at least one noise preventing member is about 0.2 mm.

11. The compressor of claim 9 , wherein the protective cover further comprises a plurality of ribs installed at the inner surface of the protective cover.

12. The compressor of claim 11 , wherein the plurality of ribs include horizontal ribs and vertical ribs.
