Abstract

A drain pan includes: a drain pan unit that includes a horizontal water receiving unit and a vertical water receiving unit intersecting with each other in an L shape and is used as horizontal and vertical types; and a water discharge socket for discharging, from the drain pan unit, drain water received on the drain pan unit. A drain port is opened through a water-receiving surface of each of the horizontal water receiving unit and the vertical water receiving unit at a corner of intersection of the drain pan unit. The water discharge socket entirely covers the drain port on an outer side of the corner, which is a major angle side.

First claim

The invention claimed is:

1. A drain pan comprising:
a drain pan unit that includes a horizontal water receiving unit and a vertical water receiving unit intersecting with each other in an L shape and is used as horizontal and vertical types; and
a water discharge socket for discharging, from the drain pan unit, drain water received on the drain pan unit, wherein
a drain port is opened through a water-receiving surface of each of the horizontal water receiving unit and the vertical water receiving unit at a corner of the intersection of the drain pan unit,
the water discharge socket entirely covers the drain port on an outer side of the corner, which is a major angle side,
the water discharge socket includes a drain water discharge pipe disposed lower than the water-receiving surface of the drain pan unit to discharge drain water externally from an instrument in which the drain pan is disposed whether the instrument is horizontally or vertically installed, and
in the drain water discharge pipe, an inflow opening port connected with the drain port includes an axial-direction cut part and a radial-direction cut part facing to the horizontal water receiving unit and the vertical water receiving unit, respectively, of the drain pan unit.

2. The drain pan of claim 1 , wherein
the water discharge socket includes two seating surfaces attached to the horizontal water receiving unit and the vertical water receiving unit, respectively, of the drain pan unit,
one of the two seating surfaces is attached to the drain pan unit by screw fastening,
an other of the two seating surfaces is attached by fitting a click protruding in the drain port onto the drain pan unit, and
the seating surface attached by screw fastening extends in parallel with the drain water discharge pipe.

3. The drain pan of claim 1 , wherein a sealing member enclosing the drain port and the inflow opening port of the drain water discharge pipe connected with the drain port is provided between the water discharge socket and the drain pan unit.

4. The drain pan of claim 1 , wherein
the drain pan unit is provided with a pipe extraction hole through which a pipe passes, and
a collar raised higher than the water-receiving surface of the drain pan unit is provided around the pipe extraction hole.

5. A refrigeration cycle apparatus comprising
the drain pan of claim 1 ,
wherein an instrument in which the drain pan is included is horizontally or vertically installed.
