When the air layer vibrates as shown by the arrow S, a secondary air propagation sound is generated, and the noise radiated from the outdoor unit is increased. Most of the vibration of the compressor 3 is absorbed by the anti-vibration rubber 2, but part of the vibration propagates to the base 1 via the support leg 8 and the anti-vibration rubber 2, and noise is generated from the base 1. There was a problem of doing.

その説明を省略する。FIG. 1 shows an embodiment of the present invention.
On the base 5 of the outdoor unit, a bowl-shaped projection 6 projecting toward the bottom surface 3a of the compressor 3 is formed. The area of the projection 6 is equal to or larger than the area of the bottom surface 3a of the compressor 3 and does not form a plane parallel to the flat bottom surface 3a of the compressor 3. Further, the top of the protrusion 6 does not contact the bottom surface 3a even when the compressor 3 moves up and down. The other configuration is the same as that of the conventional one shown in FIG. 3, and the corresponding members are denoted by the same reference numerals and description thereof will be omitted.

A sound wave is radiated from the bottom surface 3a, and the sound wave collides with the outer surface of the protrusion 6 to change its direction and is dispersed in the outer peripheral direction as shown by the arrow P. Therefore, the bottom surface 3 of the compressor 3
The air layer between a and the protrusion 6 does not vibrate, and the generation of secondary air propagation noise based on this vibration can be prevented.
In addition, the rigidity of the base 5 is increased by the protrusion 6, and the base 5
The noise based on the vibration of can be reduced.

る。According to the present invention, since the projection provided on the base and projecting toward the bottom of the compressor has a bowl shape or a conical shape that does not form a parallel surface with the bottom of the compressor, The sound wave radiated from the bottom of the compressor collides with the outer surface of the projection, changes its direction and is dispersed in the outer peripheral direction, so that the vibration of the air layer between the bottom of the compressor and the projection is eliminated, Generation of secondary airborne sound based on this vibration can be prevented. In addition, since the rigidity of the base is increased by the protrusion, noise due to vibration of the base can be reduced.
