[Operation] According to the above-described structure, the outdoor unit main body is buried underground, the refrigerant piping is arranged underground, and when the outdoor blower is operated, air enters through the suction port provided in the frame. The drain water during defrosting is blown out from the outlet through the outdoor heat exchanger and drained to the outside by the drain suction means. In addition, plants can be grown in the planter that also serves as a roof.

[0007]

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

As shown in the figure, the main body 1 of the underground outdoor unit is formed into an inverted trapezoid, and a drain pan 4 is provided on a frame 3 inclined inwardly at the bottom 2. Drain water is provided inside the drain pan 4. As a suction means, a drain water suction hose is provided, one end of which faces the drain pan 4, and the other end connected to the drain pump 7. Further, the drain pan 4 is equipped with a float switch 6 which is activated by sensing the water level, so that when the water reaches a predetermined level, the drain pump 7 is activated. The frame 3 at the bottom 2 of the main body 1 is equipped with an outdoor heat exchanger 8, a compressor 9, and an outdoor blower 11 held by a holding plate 10. A suction grill 1 that is slightly high, stands vertically over almost the entire circumference, and forms an inlet 14 and an outlet 15.
A frame 13 is provided in which the air outlet grille 4a and the outlet grille 15a are integrated. Further, filters 16 and 17 are provided above the filter. At the center of the suction port 14 and the outlet port 15, there is a base portion 18. Below the base portion 18, there is a sealed electrical box 19, and the drain pump 7 is provided with a valve to the outside of the main body 1. A drain port 20 is provided facing the drain.

[0009] Furthermore, a through hole 22 is provided in the main body 1 on a surface parallel to the pipe connection portion 21, through which a refrigerant pipe 23 is passed through and is arranged toward an indoor unit (not shown) in the room 24. The structure is as follows. Further, the refrigerant pipe 23 is buried underground from the pipe connection part 21 to near the indoor area 24. A planter 25 that also serves as a roof is installed on the upper part of the frame 13, and the planter 25 that serves as a roof is provided with a central groove 26, a drain port 27 at the end of the groove 26, and an inlet port. 14 and outlet 15
and is constructed to cover against rainwater. Plants 28 are grown inside the planter 25 which also serves as a roof.

[0010] With the above configuration, when installing an underground type outdoor unit, a square hole one size larger than the main body 1 is installed in the underground 29.
The main body 1 is buried, and the refrigerant pipe 23 is installed inside the wall of the indoor 24 or with the wall of the indoor 24 from the indoor unit (not shown) of the indoor 24.
A hole is drilled from the side of the underground unit up to the through hole 22 of the underground outdoor unit in which the refrigerant pipe 23 can be installed, and the refrigerant pipe 2 is inserted there.
3, the refrigerant pipe 23 is passed through the through hole 22, and connected to the connection pipe section 21 of the main body 1. Although the electrical wiring is not shown, it is inserted into an environmental pipe or the like and buried underground in the same way as the refrigerant pipe 23. When the burial installation is completed in this way, frame 1

plant. When the equipment is operated, the outdoor blower 11 is operated, and the outside air sucked in from the suction port 14 of the main body 1 is heat exchanged through the outdoor heat exchanger 8, condensing the refrigerant in the summer and evaporating the refrigerant in the winter. Therefore, air is blown out from the air outlet 15. Furthermore, during heating operation, the outdoor heat exchanger 8 that functions as an evaporator is frosted, and during defrosting, drain water accumulates in the drain pan 4 at the bottom 2.

Furthermore, there is a planter 25 that also serves as a roof, but when it is windy and rainy, rainwater flows through the inlet 14 and the outlet 15.
In such cases, the rainwater that has entered from the outlet 15 will flow to the bottom 2 of the main body 1.
Since the frame 3 has an inclined structure, rainwater naturally flows toward the drain pan 4. When the water level of the drain water or rainwater accumulated in the drain pan 4 becomes high, a float switch 6 installed near the drain pan 4 detects a predetermined water level and drains the drain water installed at the top of the main body 1. The pump 7 is activated, and the water suction hose 5 sucks up drain water to the upper part of the main body, and the drain water is discharged to the outside of the main body 1 through the drain port 20. When rainwater enters the roof planter 25, it naturally flows into the central groove 26 because it is sloped toward the center of the roof planter 25, and flows out through the drain port 27 at the end. It has become. Further, filters 16 and 17 attached to the upper portions of the suction port 14 and the blowout port 15 are designed to block external dust and the like.
