Abstract

PROBLEM TO BE SOLVED: To improve an operability for attaching a sound insulation member and decrease noise at low cost by fitting the peripheral edge part of a sound insulation cover capable of housing a compressor therein to a groove part formed on a bottom plate around the compressor. SOLUTION: Upon assembly of an outdoor machine 1, a compressor 10 is first attached to a central part of a circular groove 7a formed on a bottom plate 7 through vibration preventing materials 11. Then, the attached compressor 10 is covered with a cylindrical sound insulation cover 12 from the upper part thereof and the opening peripheral edge 12e of the sound insulation cover 12 is firmly fitted to the circular groove 7a on the bottom plate 7. Noise generated from the compressor 10 during the operation of the outdoor machine 1 is damped while it is transferred to a space between the compressor 10 and the sound insulation cover 12. Further, since the inner cover 12b of the sound insulation cover 12 is made of a sound insulation material, a part of the noise is interrupted. The noise passing through the inner cover 12b is absorbed by a sound absorbing material 12c provided between the inner cover 12b and an outer cover 12a and further damped. The damped noise is further interrupted by the outer cover 12a formed with a sound insulation material so that it hardly leaks outside.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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 soundproofing of a compressor.

[0002]

2. Description of the Related Art In a separate type air conditioner comprising an indoor unit and an outdoor unit, various measures have been taken with priority given to reducing the noise of the indoor unit. I didn't.

[0003] Therefore, in recent years, the noise reduction of the outdoor unit has become a great demand from the market. Since the loud noise in the outdoor unit is the operating noise of the compressor having the built-in electric motor, it is important to take soundproof measures for the compressor.

Heretofore, the most common soundproofing measure for such a compressor is known in which a soundproof cover made of a sound absorbing material such as felt or a sound insulating material is directly wound around the compressor body. .

Further, Japanese Utility Model Publication No. 3-27213 discloses that a partition plate and a fixing plate are fixed to each other in a housing while facing each other.
In the meantime, the compressor is arranged, and the soundproof cover is hardly detached by providing the locking piece of the soundproof cover on the partition plate and the fixed plate. Things are disclosed.

In addition, since the soundproof cover is not wound directly around the compressor but is spaced apart from the compressor, a space is formed between the compressor and the soundproof cover. The noise can be reduced to further reduce the noise.

[0007]

However, in such a conventional outdoor unit, the number of soundproof covers and the number of parts for mounting the soundproof covers are increased, so that the mounting becomes complicated, the workability is reduced and the cost is reduced. There was a problem of becoming high.

Accordingly, the present invention has been made to solve such a problem, and an air conditioner capable of improving the workability of mounting a soundproof member of a compressor and reducing noise at low cost. The purpose of the present invention is to provide an outdoor unit.

[0009]

To achieve the above object, the present invention relates to an outdoor unit of an air conditioner having a soundproof member for reducing noise of a compressor installed on a bottom plate. The present invention is characterized in that a soundproof lid capable of accommodating the compressor is used, and a groove is formed on a bottom plate around the compressor to be fitted with a peripheral portion of the soundproof lid.

[0010] With the above configuration, when assembling the outdoor unit, the soundproof cover is put over the compressor installed on the bottom plate, and the peripheral edge of the soundproof cover is fitted into the groove formed on the bottom plate. Since it is good, the number of parts is small and the mounting work is easy. Further, since a space is formed between the compressor and the soundproof lid, a noise reduction effect can be expected.
