[0031]
In this case, the inclined operation surface 18 is recessed from the surface of the right front plate 8 constituting the soundproof box 1 toward the accommodation space 9 in a state of being inclined by the angle θ with respect to the vertical direction as described above. Therefore, each of the push button switches 21, the display 22, and the lamps 23 provided on the inclined operation surface 18 can be retracted toward the housing space 9 from the surface of the right front plate 8, and the body of the worker can be reduced. The configuration is such that touching the push button switch 21 and the like carelessly can be reliably suppressed.
[0032]
On the other hand, since the inclination operation surface 18 is inclined so as to be recessed from the surface of the right front plate 8 toward the accommodation space 9, even when the height of the soundproof box 1 is small, the worker can maintain the inclination while maintaining the standing posture. Each push button switch 21 disposed on the operation surface 18 can be easily operated, and the display contents of the display 22 disposed on the inclined operation surface 18 and the lighting state of each lamp 23 can be easily checked. It is a configuration that can be done.
[0033]
Furthermore, by integrally forming the operation panel 16 having the mounting frame 17 and the inclined operation surface 18 using, for example, a polyamide resin, the operation panel 16 can be operated as compared with the case where the operation panel is formed using a sheet metal or the like. The configuration is such that the manufacturing cost of the panel 16 can be reduced.
[0034]
Next, an operation of attaching the above-described operation panel 16 to the right front panel 8 constituting the soundproof box 1 will be described.
[0035]
First, as shown in FIG. 6, a board 20 to which a push button switch 21, an indicator 22, and a lamp 23 are attached is prepared, and a bolt 24 inserted into each bolt insertion hole 20A of the board 20 is tilted of the operation panel 16. It is screwed to each boss 18D provided on the operation surface 18. As a result, as shown in FIG. 5, the substrate 20 is mounted on the back side of the tilt operation surface 18, and each of the push button switches 21, the display 22, and the lamps 23 has a large diameter hole 18E, It is inserted into the square hole 18F and each small-diameter hole 18G, and is disposed on the surface of the inclined operation surface 18.
[0036]
Next, the inclined operation surface 18 of the operation panel 16 on which the board 20 is mounted is inserted into an opening 8A formed in the right front plate 8 of the soundproof box 1 and is projected from the mounting frame 17 of the operation panel 16. The operation panel 16 is positioned with respect to the right front plate 8 by inserting the pin 17F into each pin insertion hole 8C of the right front plate 8.
[0037]
Then, by screwing the bolts 19 inserted into the respective bolt insertion holes 8B of the right front panel 8 to the respective bosses 17E of the mounting frame 17, as shown in FIG. Can be attached to the site.
[0038]
As a result, the inclined operation surface 18 of the operation panel 16 is recessed from the surface of the right front plate 8 toward the accommodation space 9 in a state of being inclined by the angle θ with respect to the vertical direction. The push button switch 21, the display 22, and the lamps 23 can be arranged at a position where the push button switch 21, the lamps 23, and the lamp 23 are retracted from the surface of the right front plate 8 toward the housing space 9.

[0046]
In addition, the operator can easily check the display contents of the display 22 and the lighting state of each lamp 23 provided on the inclined operation surface 18 while maintaining the standing posture. Visibility can be improved.
[0047]
Further, since the operation panel 16 including the mounting frame 17 and the inclined operation surface 18 is integrally formed using a resin material, the operation panel 16 is operated as compared with the case where the operation panel is formed using, for example, a sheet metal. The manufacturing cost of the panel 16 can be reduced.
[0048]
In the above-described embodiment, the case where the operation panel 16 is attached to the right front panel 8 constituting the soundproof box 1 is exemplified. However, the present invention is not limited to this, and may be configured to be attached to other parts such as the left front plate 7, the left side plate 3, and the right side plate 4, for example.
[0049]
In the above-described embodiment, the soundproof box 1 includes the bottom plate 2, the left and right side plates 3 and 4, the rear plate 5, the top plate 6, and the left and right front plates 7 and 8. An example is shown in which a rectangular parallelepiped box surrounded by is enclosed. However, the present invention is not limited to this. For example, a bottom plate, a cylindrical peripheral wall plate erected on the bottom plate, and a cylindrical plate surrounded by a top plate provided on the upper end side of the peripheral wall plate The soundproof box may be formed, and the operation panel 16 may be attached to the surface of the peripheral wall plate.
[0050]
Further, in the above-described embodiment, the case where the operation panel 16 is integrally formed by using a polyamide resin has been described as an example. 16 may be integrally formed. In this case, gloss can be obtained on the surface of the operation panel 16 formed of the ABS resin, so that the external appearance of the package compressor can be enhanced.
[0051]
Furthermore, in the above-described embodiment, the case where the compressor main body 11 is configured as a three-cylinder reciprocating compressor is described as an example. However, the present invention is not limited to this. For example, a reciprocating compressor having one cylinder, two cylinders, four cylinders or more may be used. Further, instead of the reciprocating compressor, another compressor such as a scroll compressor may be used.
[0052]
