  The compressor 2 is installed on the bottom surface of the outdoor unit 1 in a vibration-proofing manner and is insulated and sound-insulated by covering the periphery with a sound-insulating member 8. The sound insulation member 8 includes a body sound insulation member 9 mounted in a bellows around the body periphery of the compressor 2 and the compressor accumulator 4 that are integrally assembled, and an upper opening end of the body sound insulation member 9. And an upper sound insulating member 10 that covers the upper part of the compressor 2 and the compressor accumulator 4. Since the outer diameter of the upper sound insulating member 10 on the compressor 2 side is slightly larger than the outer diameter of the compressor accumulator 4, the planar shape is a distorted dome shape.

  As shown in FIG. 3 and FIG. 4, the body sound insulating member 9 and the upper sound insulating member 10 have three layers by attaching sound absorbing materials 12 such as felt materials to both surfaces of a cover material 11 made of an olefin sheet or the like. It has a laminated structure, and is used to insulate and prevent sound such as motor rotation sound radiated from the compressor 2, mechanical sound of the compression mechanism, or excitation sound due to the pulsation of the refrigerant. Further, a cap-shaped cover member 13 made of an olefin sheet or the like is fitted and mounted on the upper surface side of the upper sound insulating member 10 so as to cover the upper portion of the upper sound insulating member 10.

  The upper sound insulation member 10 has a through-hole through which at least two refrigerant pipes of a refrigerant discharge pipe 5A connected to the compressor 2 and a refrigerant suction pipe connected to the compressor 2 via the compressor accumulator 4 pass. 14 and 15 are provided.

Can be detected.

  As shown in FIGS. 3 to 6, the cap-shaped cover member 13 is an inclined surface that is inclined downward toward the rear side (rear side) of the compressor 2 when the upper surface 18 is installed on the upper surface of the upper sound insulating member 10. It is said that. The inclined surface of the upper surface 18 causes condensation on the surface of piping or equipment disposed in the upper part of the compressor 2, and when it is dripped onto the cover member 13 as drain water, the drain The water is guided and drained along a downwardly inclined surface in a specific direction on the rear side (back side) of the compressor 2.

  Further, on the upper surface 18 inclined downward toward the rear side, a stepped portion 20 and a discharge temperature sensor 16 that are one step higher than the periphery where a through hole 19 through which the refrigerant suction pipe 5B is passed are provided. The refrigerant discharge pipe 5A is provided with a convex tunnel-like bulging portion 21 on the upper side where the refrigerant discharge pipe 5A is disposed in the horizontal direction.

  The step portion 20 in which the through hole 19 is drilled extends from the periphery of the through hole 19 to the outer peripheral edge portion of the cover member 13, and the refrigerant suction pipe 5 </ b> B is connected between the outer peripheral edge portion and the through hole 19. A notch 22 is provided for passing through, and the cover member 13 can be mounted by passing the refrigerant suction pipe 5 </ b> B through the through hole 19 through the notch 22. On the other hand, the upwardly projecting tunnel-shaped bulging portion 21 extends from the front side of the cover member 13 to the outer peripheral edge portion on the rear side, and is disposed in the space between the inner surface and the upper surface of the upper sound insulating member 10 in the discharge temperature sensor. The refrigerant discharge pipe 5 </ b> A in which 16 is installed can be piped rearward and covers the upper part thereof.

  Further, as shown in FIGS. 5 and 6, the upper surface 18 of the cover member 13 is predetermined with respect to the outer peripheral edge portion on the front side excluding the lower downward inclined portion where the drain water is drained. And the drain water dropped on the upper surface 18 is prevented from being drained from the front side of the compressor 2. 23, it can be surely guided to a specific drainage direction on the rear side.

  Further, a bent flange portion 24 that is bent substantially vertically downward is provided on the outer peripheral edge portion of the cover member 13 over the entire circumference. As shown in FIGS. 3 and 4, the bent flange portion 24 can be fitted to the edge of the upper sound insulating member 10 whose planar shape is a deformed darby shape. Further, as shown in FIG. 6, a fitting confirmation portion 25 whose flange height is one step higher than the other portions is provided on a part of the bent flange portion 24 on the rear side. The assembly state of the cover member 13 inside the unit, that is, the fitting state of the bending flange portion 24 with respect to the edge of the upper sound insulating member 10 is visible.

  Further, the cover member 13 comes into contact with the upper surface of the upper sound insulation member 10 that is installed substantially horizontally on the upper portion of the body sound insulation member 9 that covers the outer periphery of the body portion of the compressor 2, thereby An inward recess 26 that allows the member 13 to be installed with its upper surface 18 always inclined in the direction of drain water drainage is integrally formed at two positions on the front side. As shown in FIG. 4, the cover member 13 is in contact with the upper surface of the upper sound insulating member 10 at the lower surface of the concave portion 26 at two positions on the front side where the upper surface 18 is raised, and is one of the lower surfaces on the rear side where the upper surface 18 is lowered. The unit is stably installed by contacting the outer peripheral edge of the upper surface of the upper sound insulating member 10.

With the configuration described above, according to the present embodiment, the following operational effects can be obtained.
Sounds such as motor rotation sound, mechanical sound of the compression mechanism, vibration sound due to the pulsation of the refrigerant, etc. that are dissipated to the surroundings when the compressor 2 is operated are sound-insulated and absorbed by the sound-insulating member 8 that covers the outer periphery Is reduced. On the other hand, on the surfaces of the refrigerant pipes and various devices arranged in the upper part of the machine room in which the compressor 2 is installed, condensation may occur depending on the operating conditions, which becomes drain water. In some cases, the liquid drops on the cover member 13 that covers the upper surface of the upper sound insulating member 10 installed on the upper portion of the compressor 2.

  However, the cover member 13 that covers the upper surface of the upper sound insulating member 10 has an upper surface 18 that is inclined downward in the direction of drain water drainage, and the inclined upper surface 18 has a through hole 19 through which the refrigerant suction pipe 5B is passed. A stepped portion 20 that is one step higher than the perforated periphery, and a convex tunnel-like bulged portion 21 provided above the refrigerant discharge pipe 5A provided with the discharge temperature sensor 16 are provided. It is configured.

  For this reason, even if dew condensation occurs on the surface of the pipes and devices disposed above the compressor 2 and drops on the compressor 2 as drain water, the upper surface 18 It is received by the cover member 13 that is inclined downward in the drain water drain direction, and can be quickly drained in a specific drain direction such as the rear side of the compressor 2 along the inclined surface.

  Further, since the through hole 19 for the refrigerant suction pipe 5B provided on the upper surface of the cover member 13 is formed in the stepped portion 20 that is one step higher than the surroundings, the drain water flows toward the through hole 19. From there, it can be prevented from entering the cover member 13 and reaching the main body or terminal of the compressor 2, and the upwardly projecting tunnel-shaped bulging portion 21 provided on the upper surface 18 of the cover member 13. Thus, it is possible to shield from the outside air by covering the refrigerant discharge pipe 5A and the discharge temperature sensor 16 disposed on the inner surface side.

It is possible to prevent drain water from entering the electrical wiring or the like that is wired to the wiring, short circuiting due to dripping, malfunction, corrosion or the like. Further, since heat discharge to the outside can be suppressed at a position closer to the compressor and the discharge temperature can be detected by the discharge temperature sensor, the detection accuracy of the discharge temperature can be improved, and the controllability based thereon can be improved.

  Further, the step portion 20 extends from the periphery of the through hole 19 to the outer peripheral edge portion of the cover member 13, and the notch 22 is provided between the outer peripheral edge portion and the through hole 19. The refrigerant suction pipe 5B can be passed through the through hole 19 formed in the stepped portion 20 through the notch 22 extending to the outer peripheral edge, and the drain water enters the cover member 13 from the notch 22. Can be prevented. Accordingly, it is possible to reliably prevent the drain water from entering the main body side and the terminal of the compressor 2 while ensuring the ease of installation of the cover member 13.

  Moreover, since the embankment 23 is provided in the upper surface 18 of the cover member 13 with respect to the outer-periphery edge part except the downward downward downward part from which drain water is drained, the drain dripped at the upper surface 18 of the cover member 13 The drain water is led to the rear side of the compressor 2 in a specific drainage direction by the dike 23 so that the water is not drained from a specific drainage direction, that is, from the outer peripheral edge other than the rear side of the compressor 2. Can do. Therefore, the drain water dropped on the upper surface 18 of the cover member 13 can always be drained toward a specific direction, that is, a position close to the drain port such as the rear side of the compressor.

  Further, a downward bending flange portion 24 fitted to the edge of the upper sound insulating member 10 is provided on the outer peripheral edge portion of the cover member 13. For this reason, the bending flange portion 24 provided on the outer peripheral edge portion of the cover member 13 is fitted to the edge of the upper sound insulating member 10 and the cover member 13 is installed to prevent the cover member 13 from rotating. The cover member 13 provided around one refrigerant suction pipe 5B is always set in a fixed direction by preventing rotation, and the drain water is surely specified in a specific direction. It can be drained towards.

  And since it is set as the structure which provided the fitting confirmation part 25 heightened rather than the other part in the part of the bending flange part 24, the bending flange part provided in the outer periphery part of the cover member 13 is provided. If 24 is not properly fitted to the edge of the upper sound insulation member 10, the fitting confirmation part 25 hits the upper surface of the upper sound insulation member 10 and is unnaturally inclined. As a result, the cover member 13 can be accurately assembled without any trouble in a state in which it is difficult to visually recognize inside the housing.

  Furthermore, in this embodiment, the upper sound insulation member 10 is installed substantially horizontally on the upper part of the body sound insulation member 9 covering the outer periphery of the body part of the compressor 2, and is installed horizontally on the cover member 13. An inward concave portion 26 that is in contact with the upper surface of the upper sound insulating member 10 and is installed with the cover member 13 tilted in the direction of drain water drainage is integrally formed at two locations on the front side where the upper surface 18 is raised. Therefore, the cover member 13 is always placed on the upper surface by placing the inner concave portion 26 formed on the cover member 13 in contact with the upper surface of the upper sound insulation member 10 installed horizontally. It can be installed stably by inclining in a specific direction. Accordingly, the inclined installation of the cover member 13 can be facilitated, and the drainage function of drain water can be reliably ensured.

  Moreover, by mounting the compressor 2 that has been sound-insulated as described above as an air conditioner, the accumulation of drain water on the sound-insulating member 8 that covers the outer periphery of the compressor 2 and performs sound insulation, and the main body of the compressor 2 and Short circuit, malfunction, corrosion, etc. due to dripping of drain water to the terminal, discharge temperature sensor 16, electrical wiring etc. wired in front of the compressor 2 can be prevented, and to the outside at a position closer to the compressor 2. Since the discharge temperature can be detected by the discharge temperature sensor 16 while suppressing the heat radiation, the detection accuracy of the discharge temperature can be improved and the controllability based on it can be improved. As a result, compression from the drain water generated around the compressor 2 is performed. The machine 2 can be protected and its reliability can be improved, and the controllability and control accuracy of various controls using the discharge temperature sensor 16 can be improved. That.

As an alternative to the concave portion 26, the upper surface 18 of the cover member 13 </ b> A is used. Therefore, a stepped portion (not shown) having a predetermined height is provided at a corresponding position on the upper surface of the upper sound insulating member 10 so that the drainage is always inclined in the drain water draining direction.

  As described above, even when the upper sound insulating member 10 is provided with the step portion that is in contact with the inner surface of the cover member 13A and is inclined to the drain water drain direction, By placing the inner surface of the cover member 13A in contact with the step provided on the upper surface of the installed upper sound insulation member 10, the upper surface of the cover member 13A is always inclined in a specific direction. can do. Accordingly, the inclined installation of the cover member 13A can be facilitated, and the drain water drainage function can be reliably ensured.
