Next, referring to FIG. 2, FIG. 2 is a schematic view of the machine room 8 of the outdoor unit 1, but first, the compressor 22 is located at the front face side of the partition plate 5 side of the machine room 8. The accumulator 23 is fixed to the angle 35 which is loaded through the dustproof material 34 and welded slightly to the front side body part on the opposite side to the partition plate 5 of the compressor 22. A refrigerant pipe is connected to the compressor 22 suction port from the lower end of the accumulator 23.

Refrigerant piping components such as the four-way valve 24, the electric valve 25, and the refrigerant pipe are integrally arranged at the rear of the accumulator 23, and the suction pipe 33 connected thereto is connected to the accumulator 23.

It is bent and extended, and it is simplified as a substantially U-shaped shape connected to the 4-way valve 24 attached to the partition plate 5 inside the machine room 8.

Further, the discharge pipe 36 is bent inward from the upper end of the compressor 22, extends downward in the vertical direction, bent in a U shape at the rear of the compressor 22, and near the upper end of the compressor 22, One side is bent in the horizontal direction and connected to the four-way valve 24.

Here, when the compressor 22 is operated, vibration in the rotational direction about the central axis of the compressor 22 occurs, but when it extends from the approximately center of the ceiling surface of the compressor 22 like the discharge pipe 36 The vibration is small, and it is possible to sufficiently absorb this vibration by the twist of the discharge pipe 36 in the upper part of the compressor 22 and the U-shaped bending provided in the rear part of the compressor 22.

On the other hand, when the compressor 22 vibrates in the rotational direction with respect to the suction pipe 33 extending from the accumulator 23, the accumulator 23 fixed to the side of the main body of the compressor 22 is naturally the compressor 22. Since the suction pipe 33 extended from the accumulator 23 also receives the vibration which draws a circular arc similarly, since the circular arc centered on the central axis of this is similarly U-shaped, the outdoor unit 1 Although the vibration is absorbed, since the vibration is concentrated in a portion extending downward from the upper end of the accumulator 23 in the vertical direction, approximately the middle of the suction pipe 33 extending downward as shown in FIG. Part and the spacer 32 in the substantially middle part of the accumulator 23 main body part, and are fixed by the clamper 37, so that the vibration which concentrates on this part can absorb the suction pipe. (33) It is disperse | distributed whole and absorbed.

A hole 38 for inserting the suction pipe 33 in the vicinity is provided, and an indentation portion 39 is provided from the hole 38 toward the convex arc, and the accumulator 23 has one side facing the convex arc. ) To the butt portion 40 of the shape cut out by a convex arc, and a groove 41 is provided on the side thereof to allow the clamper 37 to pass through when the suction pipe 33 is fixed to the accumulator 23. have.

The spacer 32 opens the cutout portion 39, attaches the action pipe 33 to the hole 38, and abuts the portion 40 against the accumulator 23 approximately in the middle of the clamper 37. It is fixed to surround the spacer 32 to which the furnace accumulator 23 and the suction pipe 33 are attached, and the clamper 37 passes through the groove 41 on the spacer 32.

In addition, the suction pipe 33, which is folded back from the upper end of the accumulator 23 and extends downward in the vertical direction, is fixed to the accumulator 23 to prevent the vibration of the suction pipe 33 itself. Since the rigidity of this refrigerant pipe is also high, the vibration in this portion becomes a form in which the suction pipe 33 is dispersed throughout.

In this way, the shape of the suction pipe 33 is as simple as possible, and the vibration from the compressor 22 is prevented by fixing the suction pipe 33 to the accumulator 23 with the spacer 32 having cushioning properties. The suction pipe 33 is dispersed and absorbed as a whole, and vibration transmission to the outdoor unit 1 is suppressed.
