As shown in FIG. 4, the insertion portion 94 is configured such that a portion covering the front side of the side surface of the pin 91 and a portion covering the back side are alternately arranged in the vertical direction, and is formed in a substantially cylindrical shape as a whole. ing. As shown in FIG. 5, the insertion portion 94 has a plane shape substantially the same as the horizontal cross-sectional shape of the pin 91, and an opening 94 a into which the pin 91 is inserted is formed. That is, the insertion portion 94 is in contact with substantially the entire circumference of the pin 91 in the opening 94 a and can move along the side surface of the pin 91. Therefore, by inserting the pin 91 into the insertion portion 94, the movement in all the horizontal directions can be restricted while the accumulator 6 can be displaced in the vertical direction.

  In addition to the pin 91 and the support member 92 described above, the support mechanism 9 includes a first buffer rubber 95 and a second buffer rubber 96 that prevent the support member 92 and the bottom frame 21 from coming into direct contact. The first and second shock absorbing rubbers 95 and 96 can prevent the vibration transmitted from the compressor 5 to the accumulator 6 through the pipe 8 from propagating to the bottom frame 21 when the outdoor unit 1 is operated. .

  The first buffer rubber 95 prevents the insertion portion 94 of the support member 92 and the bottom frame 21 from coming into direct contact. The first buffer rubber 95 is an annular member that is fitted into the pin 91, and is disposed between the lower end of the insertion portion 94 and the bottom frame 21 in a state where the pin 91 is inserted into the insertion portion 94.

The second buffer rubber 96 is provided at a position near the predetermined position where the accumulator 6 is erected on the upper surface of the bottom frame 21 and away from the pin 91. As shown in FIG. And has a triangular shape. In addition, a triangular opening 93a having substantially the same shape as the upper portion of the second buffer rubber 96 is formed in the bottom portion 93 of the support member 92, and the upper portion of the second buffer rubber 96 is fitted into the opening 93a. The

  Accordingly, by inserting the pin 91 into the insertion portion 94 and fitting the second buffer rubber 96 into the opening 93a, the movement of the accumulator 6 in the horizontal direction can be restricted, and the accumulator 6 is centered on the pin 91. Rotation can be restricted.

  Here, an example of a procedure for assembling the outdoor unit 1 will be described. First, the outdoor heat exchanger 4 and the compressor 5 are disposed on the bottom frame 21. Next, after the first buffer rubber 95 is fitted into the pin 91 with respect to the bottom frame 21 to which the pin 91 and the second buffer rubber 96 are attached, the accumulator 6 is erected on the bottom frame 21. At this time, the pin 91 is inserted into the insertion portion 94 of the support member 92, and the second buffer rubber 96 is fitted into the opening 93a formed in the bottom portion 93 of the support member 92, so that the accumulator 6 is erected in a self-supporting state.

Therefore, the productivity of the outdoor unit 1 is improved. In addition, the accumulator 6 is not fixed to the bottom frame 21 and is supported in a state in which the accumulator 6 can be displaced in the vertical direction. Therefore, vibration transmitted from the compressor 5 to the accumulator 6 when the outdoor unit 1 is operated. Can be transmitted to the bottom frame 21 and noise can be prevented.

  The support mechanism 9 includes a pin 91 provided on the bottom frame 21 and protruding in the vertical direction, and a support member 92 attached to the accumulator 6. The support member 92 is formed with an insertion portion 94 that is located on the side of the accumulator 6 and is movable along the side surface of the pin 91. Therefore, by allowing the insertion portion 94 to move along the extending direction of the pin 91 in a state where the insertion portion 94 is in contact with the side surface of the pin 91, a configuration for supporting the accumulator 6 so as to be displaceable in the vertical direction can be realized. At this time, it is possible to prevent the insertion portion 94 from moving in a direction in contact with the side surface of the pin 91 in the horizontal direction.

  Further, the insertion portion 94 of the support member 92 has an opening 94a into which the pin 91 is inserted. Therefore, the accumulator 6 can be displaced in the vertical direction by inserting the pin 91 into the opening 94a. Therefore, the accumulator 6 can be displaced in the vertical direction with a simple configuration. Moreover, the structure which prevents the insertion part 94 from moving to a horizontal direction can be simplified.

  Further, the opening 94a of the insertion portion 94 has a plane shape substantially the same as the cross-sectional shape of the pin 91, and the pin 91 is fitted into the opening 94a. Therefore, the structure which prevents the insertion part 94 from moving to all the directions of a horizontal direction with simple structure is realizable.

  The support mechanism 9 includes a first buffer rubber 95 that is fitted into the pin 91 and disposed between the insertion portion 94 and the upper surface of the bottom frame 21 in a state where the pin 91 is inserted into the opening 94a. . Therefore, when the outdoor unit 1 is operated, it is possible to reliably prevent the vibration of the accumulator 6 from propagating to the bottom frame 21 and generating noise.

  In addition, the support mechanism 9 is provided on a second buffer rubber 96 provided away from the pin 91 on the upper surface of the bottom frame 21 and a bottom portion 93 of the support member 92 facing the lower surface of the accumulator 6. And an opening 93a into which the buffer rubber 96 is inserted. Therefore, the accumulator 6 can be prevented from rotating around the pin 91.

  Further, the vibration of the accumulator 6 can be absorbed by the elasticity of the second buffer rubber 96. Therefore, it is possible to more reliably prevent noise from being generated when the outdoor unit 1 is operated.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 7 is a perspective view showing the accumulator in a state of being self-supporting by the holding structure according to the present embodiment.

  The support mechanism 109 includes a pin 191 provided on the bottom frame 21 like the pin 91 of the first embodiment, a support member 192 attached to the lower end of the accumulator 6, and the pin 191 and the support member 192. It mainly includes a fixture 195 that fixes the position in the horizontal direction.

  The support member 192 has a bottom portion 93 that faces the lower surface of the accumulator 6, and an insertion portion 194 that is located on the side of the accumulator 6. The insertion portion 194 has an opening 194a into which the pin 191 is inserted. The opening 194a is larger than the cross-sectional shape of the pin 191 with respect to the horizontal plane, and has a substantially arc-shaped elongated shape in plan view. The support member 192 is not directly in contact with the bottom frame 21 by the first buffer rubber 95 and the second buffer rubber 96 as in the first embodiment.

  The fixture 195 is a plate-like member in which an opening 195a having a plane shape substantially the same as the cross-sectional shape of the pin 191 with respect to the horizontal plane is formed. In a state where the pin 191 is inserted into the opening 194a, the pin 191 is inserted into the opening 195a of the fixing tool 195, and the fixing tool 195 is fixed to the insertion portion 194 with the screw 196, whereby the pin 191 and the insertion portion 194 are fixed. The position in the horizontal direction can be fixed.

  Here, a procedure for standing the accumulator 6 on the bottom frame 21 in a self-standing state when the refrigerant circuit 10 of the outdoor unit 1 is assembled will be described. First, the pin 191 and the second buffer rubber 96 are each attached to the bottom frame 21. Next, the first buffer rubber 95 is fitted into the pin 191.

  In addition, the opening 194 a formed in the insertion portion 194 of the support member 192 is larger than the cross-sectional shape of the pin 191 with respect to the horizontal plane. Since the support member 192 is attached to the accumulator 6, when the pin 191 is inserted into the opening 194a, it is necessary to lift the accumulator 6 and align the opening 194a and the pin 191. Therefore, when the opening 194a is small, it is difficult to insert the pin 191. However, in this embodiment, the pin 191 can be easily inserted into the opening 194a.

It is done.

  Note that the support member 292 is not directly in contact with the bottom frame 21 by the second buffer rubber 96 as in the first embodiment. Further, the dew proof cylinder 296 functions as a buffer material and prevents the vibration of the accumulator 6 from propagating to the bottom frame 21 via the pins 291.

  Here, a procedure for standing the accumulator 6 on the bottom frame 21 in a self-standing state when the refrigerant circuit 10 of the outdoor unit 1 is assembled will be described. First, the pin 291 and the second buffer rubber 96 are each attached to the bottom frame 21. Next, the dew-proof cylinder 296 is attached to the pin 291.
