Fluid collection and drain pan with integrated strength-enhancing structure
View Patent ↗A one-size-fits-all pan configured for supporting a fluid-producing unit. It has a perimeter wall spaced apart from a raised central structure to provide a moat-like area for flow of collected fluid toward a wall-mounted shut-off switch. When a desired maximum amount of fluid collection is exceeded, an electrical signal is sent to stop fluid production. The raised central structure comprises a hub with radially-extending ribs that each widens into a bent distal end having non-uniform height and width dimensions, and top indentations for receipt of vibration isolators that support the fluid-producing unit at a height above that of the perimeter wall. The non-raised areas around the ribs are all connected to the moat-like area to facilitate even fluid distribution within the pan. The pan further has an up-turned perimeter lip, staggered gussets, and angled corners for added strength, and may optionally have a nesting configuration for compact storage and transport.
1. A drain pan for supporting a fluid-producing unit and use with a shut-off switch electrically connected to the fluid-producing unit, said pan comprising:
a perimeter wall;
a raised central structure spaced apart inwardly from said perimeter wall so as to provide a moat configured for a flow of collected fluid toward a shut-off switch mounted on said perimeter wall, said raised central structure having a center hub, a plurality of ribs extending outwardly from said center hub, such that each said rib has a distal end widening into a bent distal end structure having non-uniform height and width dimensions, and said center hub and said bent distal ends each having at least one top indentation;
a plurality of non-raised fluid collection areas around said hub and said ribs that are each connected to said moat in a manner that facilitates and promotes even distribution of fluid within said pan; and
a plurality of vibration isolators each configured for supporting a fluid-producing unit over said raised central structure at a height above that of said perimeter wall while being secured within one of said top indentations, whereby when a group of vibration isolators selected from said plurality of vibration isolators are positioned according to fluid-producing unit size and mass for balanced and secure fluid-producing unit support, and are used in said top indentations and a shut-off switch is mounted on said perimeter wall that is electrically connected to the fluid-producing unit, and further when the fluid collection in said pan exceeds the desired maximum amount considered safe, then an electrical signal is sent from the mounted shut-off switch to the fluid-producing unit to stop its fluid production.
2. The pan of claim 1 wherein said raised central structure has a height dimension less than that of said perimeter wall.
3. The pan of claim 1 wherein said perimeter wall further comprises a mounting shelf configured for shut-off switch support in its needed position and orientation of operation by said perimeter wall.
4. The pan of claim 1 wherein said perimeter wall further comprises an up-turned lip.
5. The pan of claim 1 wherein said perimeter wall further comprises at least one angled corner.
6. The pan of claim 1 wherein said perimeter wall further comprises a plurality of strength-enhancing gussets.
7. The pan of claim 6 wherein said perimeter wall further comprises at least one horizontally-extending and strength-enhancing perimeter rib between said gussets.
8. The pan of claim 1 wherein said perimeter wall further comprises strength-enhancing features selected from a group consisting of an up-turned lip, at least one angled corner, spaced-apart gussets, spaced-apart gussets in staggered array, and gussets with at least one horizontally-extending perimeter rib between them.
9. The pan of claim 1 wherein said perimeter wall and said raised central area allow nesting of said pans in stacked array.
10. The pan of claim 1 wherein said raised central structure further comprises a tailpiece associated with said distal end of each of said ribs and said tailpiece extends from said distal end in a direction opposed to that of said bent distal end structure.
11. The pan of claim 1 wherein said pan is made from materials selected from a group consisting of polycarbonate, polycarbonate alloys, polycarbonate blends, polycarbonate alloys and blends using ABS, polycarbonate alloys and blends using PBT, polycarbonate alloys and blends using PET, polycarbonate alloys and blends using PP, materials impervious to corrosion, impact resistant materials, UV-resistant materials, heat resistant materials, and materials substantially unaffected when subjected to temperature extremes.
12. A drain pan for supporting a fluid-producing unit and use with a shut-off switch electrically connected to the fluid-producing unit, said pan comprising:
a rectangular perimeter wall having strength-enhancing features selected from a group consisting of an up-turned lip, at least one angled corner, spaced-apart gussets, spaced-apart gussets in staggered array, and gussets with at least one horizontally-extending perimeter rib between them;
a raised central structure spaced apart from said perimeter wall so as to provide a moat configured for a flow of collected fluid toward a shut-off switch mounted on said perimeter wall, said raised central structure having a center hub, a plurality of ribs extending outwardly from said center hub, such that each said rib has a distal end that widens into a bent distal end structure having non-uniform height and width dimensions, and said center hub and said bent distal ends having a plurality of top indentations;
a plurality of non-raised fluid collection areas around said hub and said ribs that are connected to said moat in a manner that facilitates and promotes even fluid distribution of fluid in said pan; and
a plurality of vibration isolators each configured for supporting a fluid-producing unit over said raised central structure as a height above that of said perimeter wall while being secured within one of said top indentations, whereby when a group of vibration isolators selected from said plurality of vibration isolators are positioned according to fluid-producing unit size and mass for balanced and secure fluid-producing unit support, and are used in said top indentations and a shut-off switch is mounted on said perimeter wall that is electrically connected to the fluid-producing unit, and further when the fluid collection in said pan exceeds the desired maximum amount considered safe, then an electrical signal is sent from the mounted shut-off switch to the fluid-producing unit to stop its fluid production.
13. The pan of claim 12 wherein said raised central structure has a height dimension less than that of said perimeter wall.
14. The pan of claim 12 wherein said perimeter wall further comprises a mounting shelf configured for shut-off switch support in its needed position and orientation of operation by said perimeter wall.
15. The pan of claim 12 wherein said raised central structure further comprises a tailpiece associated with said distal end of each of said ribs and said tailpiece extends from said distal end in a direction opposed to that of said bent distal end structure.
16. The pan of claim 12 wherein said perimeter wall and said raised central area allow nesting of said pans in stacked array.
17. The pan of claim 12 wherein said pan is made from materials selected from a group consisting of polycarbonate, polycarbonate alloys, polycarbonate blends, polycarbonate alloys and blends using ABS, polycarbonate alloys and blends using PBT, polycarbonate alloys and blends using PET, polycarbonate alloys and blends using PP, materials impervious to corrosion, impact resistant materials, UV-resistant materials, heat resistant materials, and materials substantially unaffected when subjected to temperature extremes.
