Abstract

Provided is an outdoor unit of an air conditioner which has good assembly stability by more cheaply and easily increasing mechanical strength of a housing, and in which the cost thereof is further suppressed by reducing the number of components such as screws, as an outdoor unit of a large air conditioner including two blowers. The left front pillar and the right front pillar are fixed between the front beam and the base panel hung between the front ends of the left side panel and the right side panel, and the rear pillar is fixed between the rear beam and the base panel hung between the rear ends of the left side panel and the right side panel. Therefore, the front beam and the rear beam are prevented from being distorted or bent, and thus mechanical strength of the entire housing is enhanced.

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 and a right side panel disposed along a left side end and a right side end of the base panel, a front beam hung between front ends of the left side panel and the right side panel, and a rear beam hung between rear ends of the left side panel and the right side panel, wherein an interior of the housing is partitioned into a machine chamber having a heat exchanger and a compressor at a lower portion and a blower chamber having a blower at an upper portion, with a plane including the front beam and the rear beam as a boundary, a first blower and a second blower are supported side by side by the front beam and the rear beam in the blower chamber, an air blowing port of the blower is disposed on a top surface of the housing, a front pillar for supporting an intermediate portion of the front beam is disposed between the front end of the base panel and the front beam, and a rear pillar for supporting an intermediate portion of the rear beam is disposed between the rear end of the base panel and the rear beam.

2 . The outdoor unit of an air conditioner according to claim 1 ,
wherein the heat exchanger includes a first heat exchanger and a second heat exchanger, a lower space on the first blower side is defined as a left machine chamber and a lower space on the second blower side is defined as a right machine chamber among the machine chambers, the first heat exchanger is disposed in the left machine chamber, and the second heat exchanger is disposed in the right machine chamber, and the front pillar includes a left front pillar disposed on a front surface of the left machine chamber and a right front pillar disposed on a front surface of the right machine chamber.

3 . The outdoor unit of an air conditioner according to claim 1 ,
wherein the rear pillar is disposed at a position to close the rear opening portion existing between a rear end portion of the first heat exchanger and a rear end portion of the second heat exchanger.

4 . The outdoor unit of an air conditioner according to claim 2 ,
wherein a left end of the left front pillar is fixed along the front end of the left side panel and a right end of the right front pillar is fixed along the front end of the right side panel.

5 . The outdoor unit of an air conditioner according to claim 2 ,
wherein the first heat exchanger and the second heat exchanger are respectively formed in a U-shape, and end portions of the first heat exchanger and the second heat exchanger are disposed so as to face each other, the left side panel is formed between a pair of post portions engaged with each corner portion of the left end of the base panel and the post portions, and is provided with a side suction grille for exposing a side portion of the first heat exchanger to the outside of the housing, and the right side panel is formed between a pair of post portions engaged with each corner portion of the right end of the base panel and the post portions, and is provided with a side suction grille for exposing a side portion of the second heat exchanger to the outside of the housing.

6 . The outdoor unit of an air conditioner according to claim 2 ,
wherein a front suction grille for exposing a front surface side of the first heat exchanger to the outside of the housing is integrally formed in the left front pillar, and a front suction grille for exposing a front surface side of the second heat exchanger to the outside of the housing is integrally formed in the right front pillar.

7 . The outdoor unit of an air conditioner according to claim 1 ,
wherein a front opening portion for maintenance exists between the left front pillar and the right front pillar, and a service panel for closing the front opening portion is disposed between the left front pillar and the right front pillar.
