Hereinafter, it will be described with reference to FIGS. 4 to 6.

The compressor 30 may be fixed to the base 12 in the machine room S1. The base 12 may be installed on a bottom panel that forms the bottom surface of the outdoor unit 10 or forms the exterior of the outdoor unit 10.

A space S2 for accommodating the compressor 30 is formed in the housing 10a on the upper part of the base 12, and noise generated from the compressor 30 is transmitted to the outside of the space S2. A soundproof case 100 may be positioned to prevent transmission.

In detail, the soundproof case 100 may be provided in a space formed by the machine room S1 in an internal space of the outdoor unit 10 formed by the housing 10a, and formed along the boundary of the machine room S1. Can be.

In general, the machine room S1 defines a lower space and an upper space that can be divided by a relative height, and a compressor 30 may be provided in the lower space, and the upper space controls various configurations of the air conditioner. An electric device (not shown) may be provided.

The soundproof case 100 is configured to shield or sound insulation from the transmission of noise generated by the compressor 30 to the outside, and form a width within a plane boundary formed by the machine room S1, and the compressor 30 ), but the height may be formed to a height corresponding to the lower space of the machine room S1 in which the compressor 30 is provided, excluding the electric part (not shown).

One surface of the soundproof case 100 may be positioned on the base 12. In detail, being positioned above the base 12 means that one surface of the soundproof case 100 is located at a predetermined height above the base 12, and the one surface of the soundproof case 100 and the base 12 A mount member is provided between the ), so that noise generated from the compressor 30 can be minimized from being transmitted to the outside through the soundproof case 100.

A support member 31 supporting the compressor 30 may be provided inside the soundproof case 100, and the support member 31 is connected to the lower end of the compressor 30 to provide the soundproof case 100 ) By being fixed to the inner surface of the bottom of the compressor 30 can be fixed.

Accordingly, one surface (bottom surface) of the soundproof case 100 may be positioned on the base 12, and the support member 31 may be positioned on one surface of the soundproof case 100.

More specifically, a first mount 210 may be provided between the support member 31 and one surface of the soundproof case 100, and a second mount 210 may be provided between the one surface of the soundproof case 100 and the base 12. A mount 230 may be provided.

That is, the inner surface of the support member 31 and one surface of the soundproof case 100 is provided while contacting the first mount 210, and the outer surface of the one surface of the soundproof case 100 and the base 12 The inner surface may be provided while in contact with the second mount 230.

The outer and inner surfaces may be defined based on a space formed by each member, and the inner and outer surfaces of the soundproof case 100 are the inner space S2 of the soundproof case 100 Based on, it may be understood as an inner surface facing the space S2 and an outer surface facing the outside of the space S2, and the inner surface of the base 12 may be understood as an inner surface facing the machine room S1.

Accordingly, the first mount 210 and the second mount 230 may be positioned on different surfaces based on one surface of the soundproof case 100.

It is preferable that the first mount 210 and the second mount 230 are provided at positions asymmetrical to each other with respect to one surface of the soundproof case 100.

In addition, the first mount 210 and the second mount 230 are preferably provided at positions that do not overlap with each other along the longitudinal direction of the compressor, and as in this embodiment, the compressor 30 is the base 12 When installed in a direction perpendicular to ), the first mount 210 and the second mount 230 are preferably provided at positions that do not overlap with each other along the vertical direction.

The asymmetric position or the non-overlapping position may mean that an area formed by each of the mount members is provided without overlapping areas with respect to one surface of the soundproof case 100.

That is, since the first mount 210 and the second mount 230 are provided on a path through which the structural noise of the compressor 30 is transmitted, it is possible to reduce the transmission of the noise of the compressor 30 to the outside.

If the first mount 210 and the second mount 230 are provided at a position symmetrical with respect to one surface of the soundproof case 100 so that an area of the mount member overlapping with respect to a vertical axis occurs, The path through which the structural noise of the compressor 30 is transmitted is shortened.

In addition, since the first mount 210 is positioned between the support member 31 and the bottom surface of the soundproof case 100 to support the compressor 30, the first mount 210 is outside the horizontal area formed by the compressor. It is structurally stable to be located at.

And since the second mount 230 is positioned between the one surface of the soundproof case 100 and the base 12 to support the soundproof case 100, the second mount 230 is the soundproof case 100 It is structurally stable to be located along the perimeter of one side.

Therefore, it is preferable that the first mount 210 and the second mount 230 are provided at positions that form asymmetric with respect to one surface of the soundproof case 100.

In addition, as the first mount 210 and the second mount 230 are dually applied, the degree to which the noise generated by the compressor 30 is transmitted to the outside through the soundproof case 100 is reduced, and the first mount According to the relative positions of 210 and the second mount 230, the amount of noise transmitted is reduced.

If only one of the first mount 210 or the second mount 230 is applied, a single grommet structure and a double grommet to which the first mount 210 and the second mount 230 are applied ( Grommet) structure noise transmission amount is further reduced when the double grommet structure is applied as in the present embodiment in a specific frequency band. The specific frequency band refers to a section in which a frequency ratio (wa/wo) is about 10.

In addition, the degree of reduction may vary depending on the physical properties according to the type of each grommet or the installation location of the grommet, but experimentally, when a double grommet structure is applied as in this embodiment, a single grommet structure is applied. More noise transmission was reduced.

In addition, when the first mount and the second mount are applied as in the present embodiment, it is possible to minimize errors that may occur in human factors such as the skill level of a worker installing the outdoor unit or the installation finishing method.

In general, when an operator installs the outdoor unit in the field, when the installation of a single grommet is installed out of the correct position due to inclination or error in the installation position, the single grommet rather becomes a medium to increase the level of vibration transmission through contact and noise This could lead to further leakage. That is, the degree of leakage of noise may vary depending on the skill level of the operator or the installation finishing method.

However, when the double grommet is applied as in this embodiment, the operator positions the second mount 230 on the upper part of the base and positions one surface of the soundproof case 100 on the second mount 230, and then the In the process of placing the first mount 210 on one surface of the soundproof case 100, the relative position with the second mount 230 can be checked, and the support member 31 is placed on the second mount 230. By positioning, it is possible to repeatedly check the position of each mount member when installing the outdoor unit.

On the other hand, the soundproof case 100 is provided between the base 12 and the support member 31 to form a surface on which the compressor 31 is mounted, the first plate 110 and the first plate 110 ), a second plate 102 extending in the longitudinal direction of the compressor 30 and provided to be spaced apart from the outer surface of the compressor 30 and a third plate 103 facing the first plate 110 ) Can be included.

A space S2 accommodating the compressor 30 is formed by each of the plates 110, 102, 103.

The second plate 102 may be defined as a configuration corresponding to the side surface of the soundproof case 100, and the third plate 103 may be defined as a configuration corresponding to the upper surface of the soundproof case 100.

The third plate 103 may form a partially curved surface. Because some of the inner space (S2) of the soundproof case 100 may be an unused space depending on the installation location of the pipe 3, the unused space in order to effectively utilize the inner space of the machine room (S1) This is to minimize the space.

In addition, as the third plate 103 forms a partially curved surface, the noise generated by the compressor 30 may be diffusely reflected in the space S2, thereby creating an effect of canceling each other out.

Meanwhile, the first plate 110 may be defined as a configuration corresponding to one surface of the soundproof case 100 described above.
