The surface exposed to the inlet 18 of the heat exchanger 50 is covered with a guard 19 that prevents contact with human hands or feet.

  With the above configuration, the air sucked from the suction port 18 by the rotation of the blower fan 51 is exchanged with the refrigerant by the heat exchanger 50 and then blown out through the blower passage 14 to the outside.

Next, the structure for fixing the back surface portion 3d of the partition plate 3 to the side plate 52 of the heat exchanger 50 will be specifically described with reference to FIG.
The side plate 52 has a length extending from the base 11 to the vicinity of the top plate 13 in the vertical direction, a plate-shaped heat transfer tube mounting portion 54 to which a plurality of heat transfer tubes 53 of the heat exchanger 50 are mounted, and a heat transfer tube Formed in a U-shape consisting of a first flange 55 in which the front side of the mounting portion 54 is bent toward the heat exchanger 50 and a second flange 56 in which the rear side of the heat transfer tube mounting portion 54 is bent toward the heat exchanger 50 side. Thus, the end 50a of the heat exchanger 50 on the machine room 4 side is supported.
The heat transfer tube mounting portion 54 has a first upper portion 54a and a first lower portion 54b, and is formed so that the width M of the first lower portion 54b is wider than the width L of the first upper portion 54a. The first flange 55 includes a second upper portion 55d continuous with the first upper portion 54a of the heat transfer tube mounting portion 54, a second lower portion 55e continuous with the first lower portion 54b of the heat transfer tube mounting portion 54, and a second lower portion from the second upper portion 55d. A first inclined surface portion 55a inclined toward 55e is provided, and a screw hole 55b is formed in the center of the first inclined surface portion 55a. A locking claw 55c is formed on the second lower portion 55e of the first flange 55 so as to protrude upward.

The rear surface portion 3d of the partition plate 3 includes a second inclined surface portion 3e inclined at the upper end portion 3da so as to overlap the first inclined surface portion 55a, and the second inclined surface portion 3e corresponds to the screw hole 55b of the first inclined surface portion 55a. A screw insertion hole 3f is formed at a position to be used. Further, a locking hole 3g for locking the locking claw 55c is formed in the back surface portion 3d of the partition plate 3 at a position corresponding to the locking claw 55c.
Further, a third flange 3h formed to be bent to the first flange 55 side on the right side surface side of the back surface portion 3d, and a notch at a position above the locking hole 3g to be bent to the first flange 55 side. And a notch piece 3i. The left and right positions of the partition plate 3 are positioned with respect to the side plate 52 by superimposing the third flange 3h on the heat transfer tube mounting portion 54 and bringing the notch piece 3i into contact with the left end portion 55ea of the second lower portion 55e.

  With the above configuration, in order to fix the rear surface portion 3d of the partition plate 3 to the side plate 52, first, the locking holes 3g of the partition plate 3 are connected to the locking claws 55c of the side plate 52 as shown by the dotted arrows in FIG. Lock from above. Next, the third flange 3 h of the partition plate 3 is overlapped with the heat transfer tube mounting portion 54 of the side plate 52, and the notch piece 3 i of the partition plate 3 is brought into contact with the left end portion 55 ea of the second lower portion 55 e of the side plate 52. Next, the second inclined surface portion 3 e of the partition plate 3 is aligned with the first inclined surface portion 55 a of the side plate 52. Finally, the back 3d of the partition plate 3 is fixed to the side plate 52 by tightening the screws 3j through the screw holes 55b and the screw insertion holes 3f.

According to the outdoor unit 1 described above, a screw insertion hole is formed in the second inclined surface portion 3e of the upper end portion 3da of the partition plate 3 at a position corresponding to the screw hole 55b formed in the first inclined surface portion 55a of the side plate 52. Since 3f is formed, the screw hole 55b and the screw insertion hole 3f can be visually confirmed from the upper oblique direction and screwed.
Thereby, the screw hole 55b and the screw insertion hole 3f are easy to see, and even if the partition plate 3 and the side plate 52 of the heat exchanger 50 have variations, the screw hole 55b and the screw insertion hole 3f can be easily aligned, and the partition plate When fixing 3 to the side plate 52 of the heat exchanger 50, the workability of screwing can be improved.
In the present embodiment, the second inclined surface portion 3e of the partition plate 3 is provided on the upper end portion 3da of the back surface portion 3d. However, the second inclined surface portion 3e of the partition plate 3 is relative to the first inclined surface portion 55a of the side plate 52. It may be anywhere on the back surface portion 3d according to the specific position.

Further, the side plate 52 is formed such that the width M of the first lower portion 54b of the heat transfer tube mounting portion 54 is wider than the width L of the first upper portion 54a, and the second upper portion 55d and the second lower portion 55e of the first flange 55 are formed. Since the first inclined surface portion 55a that is inclined from the second upper portion 55d toward the second lower portion 55e is provided so as to be connected, the strength of the side plate 52 that supports the heat exchanger 50 is ensured.
Thereby, even if the heat exchanger 50 is large-sized, the heat exchanger 50 can be supported with sufficient strength by the side plate 52.

Furthermore, since the second inclined surface portion 3e is provided at the upper end portion 3da of the partition plate 3, the line of sight is directed below the height of the partition plate 3 even when the outdoor unit is assembled on the floor. Therefore, it is possible to perform screwing work without the need to bend the knees and drop the waist, and when fixing the partition plate 3 to the side plate 52 of the heat exchanger 50, the workability of screwing can be improved.
Further, since the engaging claws 55c are formed so as to protrude upward on the side plate 52 of the heat exchanger 50, it is necessary to bend the knees and drop the waist in order to turn the line of sight below the height of the partition plate 3. The locking hole 3g of the partition plate 3 can be locked to the locking claw 55c.
