Next, the attachment procedure of the fan motor support member 20 when the heat exchanger 11 installed in the outdoor unit 50 is a corrugated fin heat exchanger will be described with reference to FIGS.
FIG. 8 is a perspective view showing a state before the size adjusting portion is attached to the inverted U-shaped locking plate of the fan motor support member, and FIG. 9 is a diagram showing the size adjusting portion and the buffer material on the inverted U-shaped locking plate of the fan motor supporting member. FIG. 10 is a perspective view showing a state after mounting, and FIG. 10 is a perspective view showing a state in which the inverted U-shaped locking plate of the fan motor support member is locked to the heat exchanger via the size adjusting portion and the cushioning material. It is a perspective view which shows the state which fixed the fan motor support member latched by the heat exchanger to the baseplate of the housing | casing.

  First, the buffer material 40 is fitted into the groove 31 of the size adjusting unit 30. Thereafter, the size adjusting unit 30 is inserted from below into the groove 26d of the inverted U-shaped locking plate 26 of the fan motor support member 20 with the groove 31 into which the cushioning material 40 is fitted facing downward (see FIG. 8). (See FIG. 9). At this time, the two claw portions 33 together with the size adjusting portion 30 are fitted into the groove 26 d of the inverted U-shaped locking plate 26. When the two claw portions 33 reach the stepped portion 26c provided on the inverted U-shaped locking plate 26, the two claw portions 33 jump out to the stepped portion 26c side by the elastic force and are caught by the stepped portion 26c.

  At this time, the projecting piece 34 of the size adjusting unit 30 contacts the inner upper surface of the inverted U-shaped locking plate 26, and the support plate 25 a of the fan motor support member 20 is fitted in the U-shaped regulating piece 32 of the size adjusting unit 30. The size adjusting unit 30 is fixed. In this case, the size adjusting unit 30 is restricted from moving in the left-right direction by the side pieces 32 a provided on both sides of the U-shaped restriction piece 32.

  The fan motor support member 20 is locked to the upper end portion of the heat exchanger 11 (corrugated fin type heat exchanger) through a size adjusting unit 30 fixed to the inverted U-shaped locking plate 26 (see FIG. 10). In this case, the upper end of the heat exchanger 11 is fitted into the groove 31 of the size adjusting unit 30. Thereafter, as described above, the post fixing portion 23 of the fan motor support member 20 is screwed on the convex throttle portion 4a formed on the bottom plate 4 via the burring shape portion 4b formed on the bottom plate 4. (See FIG. 11).

  By the way, when only the inverted U-shaped locking plate 26 is a sheet metal material, it is necessary to provide a screw hole shape to be fixed to the support plate 25a, and the mold modification of the fan motor support member 20 having the current shape occurs. Further, when only the inverted U-shaped locking plate 26 is made of a resin material, the mold of the fan motor support member 20 may be remodeled. There is a case in which stress is concentrated due to the vibration of the outdoor unit 50 or the vibration during the operation of the outdoor unit 50, resulting in damage. In this respect, in the present embodiment, the resin material size adjusting unit 30 is fitted into the inverted U-shaped locking plate 26 of the fan motor support member 20 without modifying the existing fan motor support member 20. Since the fitting range with the fan motor support member 20 is wide, the stress applied to the resin material size adjusting unit 30 can be dispersed.

  In addition, in the heat exchanger 11 arranged perpendicular to the bottom plate 4, the outdoor unit 50 in which a fin-and-tube heat exchanger having a high heat exchanger 11 and a wide thickness is installed. In this case, since the size adjusting unit 30 is not required, the gap between the fin-and-tube heat exchanger and the top plate 3 is the minimum necessary. On the other hand, in the present embodiment, when a corrugated fin heat exchanger using the size adjusting unit 30 is installed, the height is lower and the thickness is thinner than the fin and tube heat exchanger. Therefore, in a state where the fan motor support member 20 to which the size adjusting unit 30 is attached is locked to the corrugated fin heat exchanger, a specification is generated in which a gap is generated between the corrugated fin heat exchanger and the top plate 3. . However, since this specification has no problem in terms of performance and structural strength of the outdoor unit 50, a difference in height due to a difference in specifications of the corrugated fin heat exchanger by inserting a spacer or the like between the top plate 3 and the like. There is no need to fill the gap.

  As described above, according to the embodiment, the fan motor support member 20 corresponding to the fin-and-tube heat exchanger has a corrugated fin-type heat exchange that is lower in height and thinner than the fin-and-tube heat exchanger. In the case of use in a heat exchanger, the corrugated fin heat exchanger can be locked by simply fitting the size adjusting portion 30 in the groove 26d of the inverted U-shaped locking plate 26 provided in the fan motor support member 20. In this way, even heat exchangers of different models can be used without changing the structure of the fan motor support member itself by simply using the size adjustment unit 30. For this reason, the increase in the number of parts is minimized. It is easy to manage inventory and distribution, and resource savings can be achieved.
