Abstract

Provided is an outdoor unit of an air conditioner capable of obtaining efficient air blowing performance by optimizing a length dimension of a heat exchanger and a relative position of a blower. A front end portion is disposed closer to the left side panel than a rotation shaft of the first blower, and a rear end portion is disposed closer to the right side panel than a rotation shaft of the first blower in the first heat exchanger, and a front end portion is disposed closer to the right side panel than a rotation shaft of the second blower, and a rear end portion is disposed closer to the left side panel than a rotation shaft of the second blower in the second heat exchanger.

First claim

What is claimed is:

1. An outdoor unit of an air conditioner comprising:
a housing that includes a base panel, a left side panel that is vertically disposed at a left side end of the base panel, a right side panel that is vertically disposed at a right side end of the base panel, and a front beam and a rear beam that are respectively hung between front ends of the left side panel and the right side panel and between rear ends of the left side panel and the right side panel, an interior of the housing being partitioned into a machine chamber at a lower portion and a blower chamber at an upper portion, with a plane including the front beam and the rear beam as a boundary, the machine chamber having a left machine chamber and a right machine chamber, and the blower chamber having a left blower chamber and a right blower chamber;
a first blower and a second blower that are supported side by side on the front beam and the rear beam, the first blower being disposed in the left blower chamber, and the second blower being disposed in the right blower chamber;
a first heat exchanger and a second heat exchanger, each including a front portion having a front end portion and disposed along a front surface of the base panel, a rear portion having a rear end portion and disposed along a rear surface of the base panel, and a side portion disposed along one of the left side panel and the right side panel of the base panel between the front portion and the rear portion to be formed in a U-shape, the first heat exchanger being disposed in the left machine chamber and the second heat exchanger being disposed in the right machine chamber such that the front end portions thereof face each other, and the rear end portions face each other; and
a first air blowing port that is disposed above the first blower and a second air blowing port that is disposed above the second blower, on a top surface of the housing,
wherein in the first heat exchanger, the front end portion of the front portion is disposed closer to the left side panel than a rotation shaft of the first blower, and the rear end portion of the rear portion is disposed closer to the right side panel than the rotation shaft of the first blower, and
in the second heat exchanger, the front end portion of the front portion is disposed closer to the right side panel than a rotation shaft of the second blower, and the rear end portion of the rear portion is disposed closer to the left side panel than the rotation shaft of the second blower; and
when a first virtual line passing through an axis of the rotation shaft of the first blower and orthogonal to the front surface of the base panel is defined as LL, a second virtual line passing through an axis of the rotation shaft of the second blower and orthogonal to the front surface of the base panel is defined as LR, a distance between the first virtual line LL and the rear end portion of the first heat exchanger is defined as BL, a distance between the second virtual line LR and the rear end portion of the second heat exchanger is defined as BR, a distance between the first virtual line LL and the front end portion of the first heat exchanger is defined as AL, and a distance between the second virtual line LR and the front end portion of the second heat exchanger is defined as AR, and
the distance AL of the front end portion of the first heat exchanger satisfies 0.4×BL or more and 0.5×BL or less, and the distance AR of the front end portion of the second heat exchanger satisfies 0.4×BR or more and 0.5×BR or less.

2. The outdoor unit of an air conditioner according to claim 1 , wherein the first heat exchanger and the second heat exchanger are symmetrically disposed with a center of the housing being interposed therebetween.

3. The outdoor unit of an air conditioner according to claim 1 , wherein the first blower and the second blower are symmetrically disposed with a center of the housing being interposed therebetween.

4. The outdoor unit of an air conditioner according to claim 1 , wherein the front portion of the first heat exchanger horizontally extends in a direction toward the second heat exchanger from one end of the side portion of the first heat exchanger, and the rear portion of the first heat exchanger horizontally extends in the direction toward the second heat exchanger same as that of the front portion of the first heat exchanger from another end of the side portion of the first heat exchanger; and the rear portion of the first heat exchanger has a length in the direction toward the second heat exchanger longer than that of the front portion thereof; and
the front portion of the second heat exchanger horizontally extends in a direction toward the first heat exchanger from one end of the side portion of the second heat exchanger, and the rear portion of the second heat exchanger horizontally extends in the direction toward the first heat exchanger same as that of the front portion of the second heat exchanger from another end of the side portion of the second heat exchanger; and the rear portion of the second heat exchanger has a length in the direction toward the first heat exchanger longer than that of the front portion thereof.

5. An outdoor unit of an air conditioner comprising:
a housing that includes a base panel, a left side panel that is vertically disposed at a left side end of the base panel, a right side panel that is vertically disposed at a right side end of the base panel, and a front beam and a rear beam that are respectively hung between front ends of the left side panel and the right side panel and between rear ends of the left side panel and the right side panel, an interior of the housing being partitioned into a machine chamber at a lower portion and a blower chamber at an upper portion, with a plane including the front beam and the rear beam as a boundary, the machine chamber having a left machine chamber and a right machine chamber, and the blower chamber having a left blower chamber and a right blower chamber;
a first blower and a second blower that are supported side by side on the front beam and the rear beam, the first blower being disposed in the left blower chamber, and the second blower being disposed in the right blower chamber;
a first heat exchanger and a second heat exchanger, each including a front portion having a front end portion and disposed along a front surface of the base panel, a rear portion having a rear end portion and disposed along a rear surface of the base panel, and a side portion disposed along one of the left side panel and the right side panel of the base panel between the front portion and the rear portion to be formed in a U-shape, the first heat exchanger being disposed in the left machine chamber and the second heat exchanger being disposed in the right machine chamber such that the front end portions thereof face each other, and the rear end portions face each other; and
a first air blowing port that is disposed above the first blower and a second air blowing port that is disposed above the second blower, on a top surface of the housing,
wherein in the first heat exchanger, the front end portion of the front portion is disposed closer to the left side panel than a rotation shaft of the first blower, and the rear end portion of the rear portion is disposed closer to the right side panel than the rotation shaft of the first blower, and
in the second heat exchanger, the front end portion of the front portion is disposed closer to the right side panel than a rotation shaft of the second blower, and the rear end portion of the rear portion is disposed closer to the left side panel than the rotation shaft of the second blower;
