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, respectively, 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, and further includes
a blower chamber having first and second blowers supported side by side by the front beam and the rear beam at an upper portion of the housing, and
a machine chamber having a first heat exchanger, a second heat exchanger, and a compressor at a lower portion of the housing, the lower portion being partitioned from the upper portion with a plane including the front beam and the rear beam as a boundary, the first heat exchanger housed on a first blower side defined as a left machine chamber, the second heat exchanger housed on a second blower side defined as a right machine chamber;

an air blowing port of the first and second blowers disposed on a top surface of the housing;
a front pillar for supporting an intermediate portion of the front beam, disposed between a front end of the base panel and the front beam, and including
a left front pillar disposed on a front surface of the left machine chamber and integrally formed with a front suction grille for exposing a front surface side of the first heat exchanger to outside of the housing, a left end of the left front pillar being fixed along the front end of the left side panel, and
a right front pillar disposed on a front surface of the right machine chamber and integrally formed with a front suction grille for exposing a front surface side of the second heat exchanger to the outside of the housing, a right end of the right front pillar being fixed along the front end of the right side panel; and

a rear pillar for supporting an intermediate portion of the rear beam, disposed between a rear end of the base panel and the rear beam,
wherein each of the first and second heat exchangers includes a front portion disposed along the front end of the base panel, a side portion disposed along the corresponding left or right side end of the base panel, and a rear portion disposed along the rear end of the base panel, to have a U-shape, end portions of the first heat exchanger and the second heat exchanger being disposed so as to face each other.

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

3. The outdoor unit of the air conditioner according to claim 1 ,
wherein the left side panel includes a pair of post portions engaged with corner portions of the left side end of the base panel, respectively, and a side suction grille formed between the pair of post portions for exposing the side portion of the first heat exchanger to the outside of the housing, and
the right side panel includes a pair of post portions engaged with corner portions of the right side end of the base panel, respectively, and a side suction grille formed between the pair of post portions of the right side panel for exposing the side portion of the second heat exchanger to the outside of the housing.

4. The outdoor unit of the 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.

5. The outdoor unit of the air conditioner according to claim 4 , wherein the left front pillar and the right front pillar are disposed between the front end of the base panel and the front beam to support the front beam.

6. The outdoor unit of the air conditioner according to claim 5 , further comprising
one front panel disposed between the front beam and the top surface of the housing and connecting the left side panel and the right side panel for covering a front surface side of the blower chamber,
wherein the service panel is disposed between the front beam and the base panel, and includes
an upper service panel covering an upper side of the front opening portion, and
a lower service panel arranged between the upper service panel and the base panel and covering a lower side of the front opening portion.

7. The outdoor unit of the air conditioner according to claim 6 , further comprising an electric component box disposed on a rear surface of the upper service panel and between front end portions of the first and second heat exchangers, the electric component box being connected to the right and left front pillars.
