Description

  Embodiments according to the present invention relate to an outdoor unit of an air conditioner.

  The compressor disposed in the casing of the outdoor unit is supported on a bottom plate of the casing by a support member having rubber elasticity.

  This compressor must avoid deformation due to collision or contact with the bottom plate of the casing due to displacement due to accidental impact load during transportation of the outdoor unit or displacement due to vibration during operation of the compressor.

  Therefore, in the conventional outdoor unit of an air conditioner, the flange provided near the bottom of the compressor is supported on the bottom plate of the casing by a support member, while the bottom plate of the casing is recessed so as to avoid the bottom of the compressor. By immersing the rubber sheet between the recessed portion and the compressor, collision or contact between the compressor and the bottom plate of the casing was prevented.

  By the way, the conventional compressor is equipped with the flange in the boundary part of a cylindrical trunk | drum and an arc-shaped end plate.

  However, the flange that supports the compressor is not necessarily provided not only at the boundary portion between the body portion and the end plate, but also at the general portion of the body portion that is remote from the boundary portion.

  When the compressor is displaced around the flange due to impact load or vibration, a flange is provided in the general part of the body away from the boundary compared to the compressor in which the flange is arranged at the boundary between the body and the end plate. In the compressor, the displacement at the lower end portion of the body portion is larger. And in the compressor in which the flange is provided in the general part of the body part away from the boundary part, since the displacement at the lower end part of the body part becomes large, contact between the compressor and the bottom plate of the casing, interference, and There will be concerns about collisions.

  The contact, interference, and collision between the compressor and the bottom plate of the casing cause noise, reduce the performance of the compressor, and cause deformation of the bottom plate.

  Therefore, the present invention avoids contact, interference, and collision between the compressor and the bottom plate of the housing, even in a compressor in which a flange is provided in the general part of the body part away from the boundary part. We propose an outdoor unit for an air conditioner having a support structure with sufficient margin.
