1 is an exploded perspective view of an outdoor unit 8 of a refrigeration cycle apparatus according to Embodiment 1 of the present invention. Here, the outdoor unit 8 is completed by sequentially assembling each device on the unit base 2 placed on the base foot 3. For example, the compressor 4, the heat exchanger 5, the blower motor 6, the fan 7, and the like. These devices, together with other devices and members, are surrounded by a cabinet (not shown) at the four corners.
A drain pan 1 is attached to the lower part of the unit base 2.

FIG. 2 is a perspective view showing the structure of the unit base 2 and the drain pan 1 of the outdoor unit 8 of the refrigeration cycle apparatus. FIG. 3 is a perspective view of the structure of the drain pan 1.
As shown in FIG. 2, the unit base 2 is placed on two base legs 3 provided at the lower part of the outdoor unit 8, and the drain pan 1 is placed at the lower part of the unit base 2. It is arranged between the two base legs 3.
The unit base 2 has a tray structure, and a compressor 4, a heat exchanger 5 and the like are assembled on the top thereof. Further, a hole is formed in the bottom surface of the unit base 2 so that drain water generated in the heat exchanger 5 can be discharged.
The drain pan 1 is formed so as to receive drain water discharged from the unit base 2. The drain water once received by the drain pan 1 is discharged from the drain port 12 to the outside of the outdoor unit 8.

The side plates 1A and 1B of the drain pan 1 have different shapes in the center portion and the left and right portions, and the left side portion (drain port 12 side) shown in the figure has a higher height from the bottom portion to the upper end surface of the drain pan than the center portion. The portion has a shape inclined from the central portion toward the right end portion.
As shown in FIGS. 2 and 3, the side plates 1A and 1B of the drain pan 1 and the side plates 2A and 2B of the unit base 2 have fixing holes 1Aa to 1Ac, 1Ba to 1Bc, 2Aa to 2Ac, 2Ba, respectively. ~ 2Bc are provided.

Further, the fixing holes 1Ab and 1Bb are provided at a position (height Hb) where the height from the bottom surface of the drain pan 1 is higher than the height Ha in the central portion of the side plates 1A and 1B of the drain pan 1. .
Corresponding to the fixing holes of the drain pan 1, the fixing holes 2Aa to 2Ac and 2Ba to 2Bc of the unit base 2 are provided at the same height position in six places from the bottom surface of the unit base.
As described above, an inclined portion is provided on the right side of the side plates 1A and 1B of the drain pan 1 in the figure. This inclination is for preventing the drain pan 1 from coming into contact with the unit base 2 when the drain pan 1 is inclined and attached to the unit base 2 as will be described later.

FIG. 4 is a side view showing a first mounting structure (parallel fixing) of drain pan 1 according to Embodiment 1 of the present invention.
This first mounting structure shows a fixing mode of the drain pan 1 when the outdoor unit 8 is transported. That is, the fixing holes 1Ac, 1Bc provided in the drain pan 1 and the fixing holes 2Ac, 2Bc of the unit base 2 shown in FIGS. 2 and 3 are coupled by the fastening member 10 such as a bolt, and are provided in the drain pan 1. The drain pan 1 is attached and fixed to the lower portion of the unit base 2 by connecting the fixing holes 1Aa and 1Ba to the fixing holes 2Aa and 2Ba of the unit base 2 with the fastening member 10 in the same manner.
The drain pan 1 attached in this manner is installed in parallel and in close contact with the bottom surface of the unit base 2.

By the way, since the conventional drain pan mounting structure is fixed, when it is desired to make the drain water easily flow toward the drain port, the drain pan is tilted from the beginning and attached with an inclination. In this case, the height Hc of the base foot 3 is increased by the inclination, and the height of the outdoor unit 8 must be increased accordingly.
However, in the first embodiment, as described above, the drain pan 1 is attached in parallel and closely to the unit base 2 by fixing the drain pan 1 in parallel to the unit base 2 during transportation. Therefore, a space is provided between the installation installation surface 13 of the outdoor unit 8 and the drain pan 1 for passing a lifting tool (not shown) for transporting the outdoor unit 8 and a forklift claw (not shown). be able to.

Next, a second mounting structure (inclination fixing) of the drain pan 1 according to Embodiment 1 of the present invention will be described with reference to FIG. 2, FIG. 3, and FIG. That is, this 2nd attachment structure shows the fixation aspect of the drain pan 1 in the case of installing in the final installation place of the outdoor unit 8.
First, the fixing holes 1Ac, 1Bc provided in the drain pan 1 and the fixing holes 2Ac, 2Bc of the unit base 2 shown in FIG. 2 and FIG. 3 are coupled by a fastening member 10 such as a bolt. Next, the fixing holes 1Ab, 1Bb provided in the drain pan 1 and the fixing holes 2Ab, 2Bb of the unit base 2 are coupled by the fastening member 10, and the drain pan 1 is attached and fixed to the lower part of the unit base 2.
The drain pan 1 attached in this manner is fixedly installed with an inclination with respect to the installation installation surface 13 of the outdoor unit 8.

Thus, in a state where the outdoor unit 8 is installed at the installation location, the drain water generated in the heat exchanger 5 during operation can easily flow toward the drain port 12 of the drain pan 1 by inclining the drain pan 1. Become. Therefore, the malfunction that drain water overflows or drain water does not flow does not occur.
The height Hc of the base foot 3 is secured to a dimension length necessary for mounting the drain pan 1 at an angle. At this time, the overall height of the outdoor unit 8 is determined by determining the height Hc of the base foot 3 so that the distance between the inclined drain pan 1 and the installation surface 13 of the outdoor unit 8 is close (for example, close to 0). Can be kept as low as possible.

  Furthermore, since the inclination angle of the drain pan 1 is determined by the difference in the height dimensions of Ha and Hb described above, the dimensional difference should be increased if it is desired to increase the inclination angle. When it is desired to reduce the inclination angle, the dimensional difference may be reduced. Of course, the inclination angle can be adjusted by the mounting pitch (interval) of the fixing holes in the horizontal direction.

Embodiment 2. FIG.
Next, a third mounting structure (inclination-free fixing) of the drain pan 1 according to Embodiment 2 of the present invention will be described with reference to FIGS. 2, 3, and 6. FIG.
First, the fixing holes 1Ac, 1Bc provided in the drain pan 1 and the fixing holes 2Ac, 2Bc of the unit base 2 shown in FIG. 2 and FIG. 3 are coupled by a fastening member 10 such as a bolt.
Next, the connecting holes 1Aa and 1Ba provided in the drain pan 1 and the fixing holes 2Aa and 2Ba of the unit base 2 are respectively connected to the connecting variable members 11 such as chains and mounting plates by using fastening members 10 such as bolts. Fix it. By doing so, the fixing holes 1Ac, 1Bc, 2Ac, 2Bc and the fastening member 10 serve as fulcrums, and the drain pan 1 can be rotated.
For example, when a chain is used as the connection variable member 11, the inclination angle of the drain pan 1 can be varied by giving a margin to the length of the chain in advance and arbitrarily changing the fixing position of the chain. .

In addition, as shown in FIG. 6, when the mount 9 is installed under the base foot 3 and the height Hd is secured between the unit base 2 of the outdoor unit 8 and the installation installation surface 13 of the outdoor unit 8, By changing the fixing location of the variable member 11, the drain pan 1 can be greatly inclined by the height dimension of the gantry 9 as compared with the case of FIG. 5.
That is, the inclination angle of the drain pan 1 can be arbitrarily set by changing the fixing location of the coupling variable member 11 and changing the length.

In areas with high humidity, the amount of drainage increases. Therefore, the conventional drain pan needs to make the bottom of the drain pan deep so that drain water does not overflow from the drain pan. Also, if the installation surface of the outdoor unit is inclined, the drain water may not flow easily due to the inclination angle or the like.
However, in this Embodiment 2, since the inclination angle of the drain pan 1 can be arbitrarily changed, drainage is improved by taking a large inclination angle, so that the area where the outdoor unit 8 is installed and the installation surface is somewhat horizontal. It is not necessary to consider the degree.

By the way, in the above description, the drain pan 1 mounting structure according to the situation has been described. However, by removing the fastening member 10, the drain pan 1 can be changed in inclination angle at any time. Can also be removed. That is, the drain pan 1 can be removed for cleaning and maintenance.
Further, if the mounting pitch (interval) in the horizontal direction of each fixing hole is adjusted, the drain pan 1 is rotated 180 degrees in the horizontal direction so that the drain drainage take-out position of the drain pan 1 is changed from the front side of the outdoor unit 8 to the rear side. Can be switched to the side.

In addition, as for the position in the height direction of the fixing hole, the fixing holes 1Aa to 1Ac and 1Ba to 1Bc of the side plates 1A and 1B of the drain pan 1 are set at the same height from the bottom surface of the drain pan 1, and The heights of the fixing holes 2Aa to 2Ac and 2Ba to 2Bc of the plates 2A and 2B may be changed. At this time, the fixing holes of the unit base 2 are provided so as to reduce the heights of the central portions 2Ab and 2Bb.
Further, the number of fixing holes is not limited to three each. For example, if the fixing holes are provided at four or more positions by changing the height from the bottom stepwise, the mounting angle of the drain pan 1 can be set to the installation of the outdoor unit 8. The installation surface 13 can be changed in stages.
