Abstract

The present disclosure relates to an air conditioner including an indoor unit and an outdoor unit connected to the outdoor unit. The outdoor unit includes: an outdoor unit housing and a refrigerant pipe disposed inside the outdoor unit housing; case holes configured to allow a cable to pass through and electrical equipment cases disposed inside the outdoor unit housing; a cable guide disposed on a cable passage through which the cable passes toward the case holes, wherein the cable guide includes a guide body configured of cover the cable passage to block a leaked refrigerant from being introduced into the case holes along the cable passage when a refrigerant leaks from the refrigerant pipe. In addition, the cable guide includes a guide opening formed in the guide body to allow the cable to pass through, and a cable fixer including a fixer body coupled with the cable and inserted into the guide opening to fix the cable to the guide body and cover the guide opening.

First claim

What is claimed is:

1 . An outdoor unit of an air conditioner comprising:
an outdoor unit housing; a refrigerant pipe disposed inside the outdoor unit housing; electrical equipment cases disposed inside the outdoor unit housing and comprising case holes configured to allow a cable to pass through; and a cable guide disposed on a cable passage through which the cable passes toward the case holes, wherein the cable guide comprises: a guide body configured to cover the cable passage to block a leaked refrigerant from being introduced into the case holes along the cable passage based on a refrigerant leaking from the refrigerant pipe; a guide opening formed in the guide body to allow the cable to pass through; and a cable fixer comprising a fixer body coupled with the cable and inserted into the guide opening and configured to fix the cable to the guide body and cover the guide opening.

2 . The outdoor unit according to claim 1 , further comprising
a partition plate configured to partition the electrical equipment cases from a space in which the refrigerant pipe is disposed, wherein the partition plate comprises: a first partition on an upper surface of which the electrical equipment case is seated; and a second partition extending downward from the first partition to form the cable passage with respect to the space in which the refrigerant pipe is disposed.

3 . The outdoor unit according to claim 2 , wherein
the outdoor unit housing further comprises a front cover configured to cover the front of the outdoor unit, and a part of the front cover is in contact with the second partition to form the cable passage together with the partition plate.

4 . The outdoor unit according to claim 3 , wherein
the outdoor unit housing further comprises a side cover configured to cover a side of the outdoor unit, and a part of the side cover is in contact with the part of the front cover to form the cable passage together with the part of the front cover.

5 . The outdoor unit according to claim 3 , wherein
the cable guide is configured to be slidable from a first position adjacent to the front cover to a second position at the rear of the first position.

6 . The outdoor unit according to claim 5 , wherein
the cable guide further comprises a guide opening portion configured to be open toward the front to communicate with the guide opening.

7 . The outdoor unit according to claim 6 , wherein
the front cover further comprises a front cover extension part configured to cover a portion of a side of the outdoor unit based on the front cover covering the front of the outdoor unit, and the front cover extension part is configured to cover the guide opening portion from the side based on the cable guide being in the first position.

8 . The outdoor unit according to claim 7 , wherein
the front cover extension part is configured to not cover the guide opening portion from the side based on the cable guide being in the second position.

9 . The outdoor unit according to claim 5 , further comprising
an extension disposed adjacent to the second partition to form the cable passage together with the partition plate, wherein the cable guide is slidably coupled to the extension member.

10 . The outdoor unit according to claim 3 , wherein
the front cover comprises front sealing members comprising seals configured to be in contact with the partition plate based on the front cover covering the front of the outdoor unit, and the front sealing members block the leaked refrigerant from being introduced into the cable passage when the refrigerant leaks from the refrigerant pipe.

11 . The outdoor unit according to claim 4 , wherein
the electrical equipment case comprises an electrical equipment case surface disposed to face the side of the outdoor unit, the side cover comprises side sealing members comprising seals attached to an inner surface of the side cover facing the one surface of the electrical equipment case, and the side sealing members are configured to be in contact with an outer edge of the one surface of the electrical equipment case based on the side cover covering the side of the outdoor unit.

12 . The outdoor unit according to claim 3 , wherein
the front cover comprises a plurality of front exhaust holes arranged in upward and downward directions along the cable passage and configured to discharge the leaked refrigerant being introduced into the cable passage based on the refrigerant leaking from the refrigerant pipe.

13 . The outdoor unit according to claim 4 , wherein
the side cover comprises a plurality of side exhaust holes configured to discharge leaked refrigerant accumulated in a space in which the refrigerant pipe is disposed based on the refrigerant leaking from the refrigerant pipe.

14 . The outdoor unit according to claim 6 , wherein
the cable fixer is configured to be removable from the guide opening through the guide opening portion to separate the cable from the guide body.

15 . An outdoor unit of an air conditioner comprising:
an indoor unit of the air conditioner; and an outdoor unit of the air conditioner configured to be connected to the indoor unit of the air conditioner, wherein the outdoor unit of the air conditioner comprises: an outdoor unit housing; a refrigerant pipe disposed inside the outdoor unit housing; an electrical equipment case including case holes formed to allow the cable to pass through, and disposed inside the outdoor unit housing; and a cable guide disposed on a cable passage through which the cable passes toward the case holes, wherein the cable guide is configured to cover the cable passage in order to block the leaked refrigerant from being introduced into the case holes along the cable passage based on a refrigerant leaking from the refrigerant pipe.

16 . The outdoor unit according to claim 15 , wherein the cable guide includes:
a guide body configured to cover the cable passage, a guide opening formed in the guide body to allow the cable to pass through and a cable fixer comprising a cable fixer comprising a fixer body coupled with the cable and inserted into the guide opening and configured to fix the cable to the guide body and cover the guide opening.

17 . The outdoor unit according to claim 16 , further comprising
a partition plate provided to partition the electrical equipment cases from a space in which the refrigerant pipe is disposed, wherein the partition plate include: a first partition on an upper surface of which the electrical equipment case and a second partition extending downward from the first partition to form the cable passage with respect to the space in which the refrigerant pipe is disposed.

18 . The outdoor unit according to claim 17 , wherein
the outdoor unit housing further comprises: a front cover configured to cover the front of the outdoor unit, and a side cover configured to cover a side of the outdoor unit, wherein a part of the front cover is configured to be in contact with the second partition and a part of the side cover is configured to be in contact with the part of the front cover, so that the second partition, the part of the front cover, and the part of the side cover form the cable passage together.
