Abstract

An apparatus includes a drain pan configured to receive liquid condensate from a horizontal evaporator coil above the drain pan and a drain pan extension coupled to the drain pan. A pin on the front and rear sides of the drain pan extension is fitted and movable within a corresponding notch in the front and rear sides of the drain pan. The drain pan extension is securably configurable in a first configuration and a second configuration. In the first configuration, the drain pan extension extends above the drain pan at a first predefined angle relative to the drain pan. In the second configuration, at least a portion of the drain pan extension extends beyond the left pan side of the drain pan at a predefined angle, which may be selected for improved capture of liquid condensate from the horizontal evaporator coil.

Dependent claims

An apparatus comprising:

a drain pan configured to receive liquid condensate from a horizontal evaporator coil positioned above the drain pan, the drain pan comprising:
a pan base comprising a top pan surface;
a left pan side extending along a left pan edge of the pan base and extending in an upward direction from the top pan surface of the pan base;
a right pan side extending along a right pan edge of the pan base and extending in the upward direction from the top pan surface of the pan base;
a front pan side extending along a front pan edge of the pan base and extending in the upward direction from the top pan surface, the front pan side comprising a first horizontal notch, wherein the first horizontal notch extends along a portion of the front pan side;
and
a rear pan side extending along a rear pan edge of the pan base and extending in the upward direction from the top pan surface, the rear pan side comprising a second horizontal notch, wherein the second horizontal notch extends along a portion of the rear pan side;
and
a drain pan extension slidably coupled to the drain pan, the drain pan extension comprising:
an extension base comprising a top extension surface and a bottom extension surface;
a front extension side extending along a front edge of the extension base and extending in the upward direction from the top extension surface, wherein an outer surface of the front extension side comprises a first pin positioned a first distance from a right edge of the extension base, wherein the first pin is fitted and horizontally movable within the first horizontal notch;
and
a rear extension side extending along a rear edge of the extension base and extending in the upward direction from the top extension surface, wherein an outer surface of the rear extension side comprises a second pin positioned the first distance from the right edge of the extension base, wherein the second pin is fitted and horizontally movable within the second horizontal notch;
wherein the bottom extension surface of the extension base comprises one or more first stoppers positioned a second distance from the right edge of the extension base such that the drain pan extension is securably configurable in:
a first configuration in which the drain pan extension extends above the drain pan at a first predefined angle relative to the drain pan;
and
a second configuration in which the one or more first stoppers contact the left pan side, and at least a portion of the drain pan extension extends beyond the left pan side of the drain pan at a second predefined angle relative to the drain pan.

and
a rear extension side extending along a rear edge of the extension base and extending normal to the top extension surface of the extension base, wherein an outer surface of the rear extension side comprises a second pin positioned the first distance from the right edge of the extension base, wherein the second pin is fitted and horizontally movable within the second horizontal notch;
wherein the bottom extension surface of the extension base comprises one or more first stoppers positioned a second distance from the right edge of the extension base such that the drain pan extension is securably configurable in:
a first configuration in which the drain pan extension extends above the drain pan at a first predefined angle relative to the drain pan;
and
a second configuration in which the one or more first stoppers contact the left pan side, and at least a portion of the drain pan extension extends beyond the left pan side of the drain pan at a second predefined angle relative to the drain pan.
