BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outdoor unit of an air conditioner, and more particularly, to an improvement in a mounting and holding structure of a compressor to an outdoor unit main body.

[0002]

2. Description of the Related Art An air conditioner commonly used is configured such that an indoor unit installed in a room to be air-conditioned and an outdoor unit installed outside a building are connected via a refrigerant pipe or the like. And the outdoor unit is considered as close as possible to the wall surface of the building so as not to be in the way.

Conventionally, an outdoor unit main body has a bottom plate, a front plate which stands upright along a side edge of the bottom plate and is provided with a front part and a top part provided with a fan guard, a side part and a rear part. And a rear plate to be integrated.

[0004] A blower mounting base is provided on the bottom plate, and an outdoor blower including a fan motor and a fan is mounted and fixed thereto. The fan is opposed to a fan guard on the front plate.

A heat exchanger formed in an L-shape in plan view is disposed along the side and rear of the bottom plate so as to surround the outdoor blower.

[0006] On the other hand, a partition plate is provided between a side portion of the blower and an end portion of the heat exchanger to partition the inside of the outdoor unit main body. The inside of the outdoor unit body in which the blower and the heat exchanger partitioned by the partition plate are arranged is called a heat exchange room, and the other is called a machine room.

[0007] A compressor is arranged in the machine room, and further accommodates a refrigerant pipe connected to the compressor, an accumulator, a capillary tube and the like.

A packed valve mounting plate for mounting and fixing the packed valve is provided upright on the side of the outdoor unit main body which is the side of the machine room. A packed valve cover is attached in a state where the packed valve is attached, and covers the packed valve and a pipe end connected to the packed valve.

[0009] Along with the connection pipe, an external wiring including a signal line and a power supply line is wound around with a decorative tape. The external wiring extends from a wiring lid provided above the packed valve cover.
