Abstract

Disclosed are portable, easy-to-install apparatuses for detecting and containing fluid leaked or otherwise discharged from a fluid-filled device and for facilitating testing and maintenance of the apparatus and fluid-filled devices. In one aspect of the disclosed invention, upon sensing a fluid discharge, the apparatus activates audible and/or visual alarms and directs the discharged fluid to a predetermined drainage area to prevent damage to areas surrounding the fluid-filled device. In another aspect of the present invention, no plumbing or electrical wiring is required to install the apparatus, thereby allowing an unskilled individual to easily and inexpensively install the apparatus. In yet another aspect of the present invention, the apparatus may be easily located since it is not dependent on gravity or a drainage pipe for discharge of the fluid. Furthermore, the apparatus optionally includes an integral leveling mechanism to accommodate leveling of the apparatus when placed on uneven surfaces.

Claims

1. A fluid detection and containment apparatus for fluid-filled devices comprising:

a base having a first section and a second section, said first section including a canal located between an exterior wall and a centrally-located platform, said canal having a tapered floor such that fluid in contact with said floor is gravitationally directed to a reservoir located between and at least partially within said first section and said second section;

at least one fluid detector having at least one control point, for detecting at least one of the group consisting of a presence of said fluid, a height of said fluid, and combinations thereof for activating said control point upon such detection;

at least one water displacement mechanism located in or proximate to said reservoir having at least one control circuit coupled to said control point, said control circuit controlling said water displacement mechanism based upon a status of said control point; and

at least one fluid conduit in fluid communication between said reservoir and at least one drainage area;

wherein energization of said water displacement mechanism causes said fluid in said reservoir to be discharged from said reservoir through said fluid conduit to said drainage area.

2. An apparatus according to claim 1, wherein said base includes at least one aperture for facilitating attachment of at least one of the group consisting of said fluid detector, said water displacement mechanism, said fluid conduit, a frame, an alarm mechanism, a leveling mechanism, a level indicator, and combinations thereof to said base.

3. An apparatus according to claim 2, wherein said at least one aperture is labeled to facilitate installation.

4. An apparatus according to claim 1, wherein said base includes at least one cavity for insertion of at least one of the group consisting of said fluid detector, said water displacement mechanism, said fluid conduit, a frame, an alarm mechanism, a leveling mechanism, a level indicator, and combinations thereof to said base.

5. An apparatus according to claim 4, wherein said at least one cavity is labeled to facilitate installation.

6. An apparatus according to claim 1, wherein at least a portion of said exterior wall is raised.

7. An apparatus according to claim 1, wherein said at least one drainage area is selected from the group consisting of a sink, drain, home sewage drain, French drain, well, basement sump drain, water system outlet, and an outside environment.

8. An apparatus according to claim 1, wherein said fluid-filled device is selected from the group consisting of a hot water heater, an air conditioning unit, a dehumidifier, a humidifier, a water cooler, a planter, and an aquarium.

9. An apparatus according to claim 1, further comprising:

a frame for mounting atop said platform;

wherein said frame provides structural support for said fluid-filled device.

10. An apparatus according to claim 9, wherein said frame includes at least one central supporting member, at least one circular supporting member, and a plurality of radial supporting members.

11. An apparatus according to claim 1, further comprising:

an alarm mechanism for alerting a user upon detection of at least one of the group consisting of a presence of said fluid and a height of said fluid.

12. An apparatus according to claim 11, wherein said alarm mechanism includes at least one of the group consisting of a lamp, a horn, a silence switch, a reset, and combinations thereof.

13. An apparatus according to claim 1, further comprising:

at least one leveling mechanism for adjusting a height of said base.

14. An apparatus according to claim 13, wherein said leveling mechanism is at least one of the group consisting of a leveling wedge, a leveling leg, and combinations thereof.

15. An apparatus according to claim 13, further comprising:

a level indicator for indicating a horizontal orientation of said base.

16. An apparatus according to claim 15, wherein said level indicator is a leveling eye.

17. An apparatus according to claim 1, further comprising:

a plug electrically coupled to at least one of the group consisting of said water displacement mechanism, said fluid detector, and combinations thereof;

wherein power is provided to said apparatus via connection of said plug to an electrical receptacle.

18. An apparatus according to claim 1, wherein said water displacement mechanism and said fluid detector are included in a single water displacement assembly.

19. An apparatus according to claim 18, wherein said water displacement assembly further includes at least one of the group consisting of a tank, a covering, a plug, a cord, alarm mechanism wiring, a discharge aperture, a discharge aperture assembly, an intake aperture, and combinations thereof.

20. An apparatus according to claim 18, wherein said water displacement assembly is a condensate removal assembly.

21. An apparatus according to claim 1, wherein said base is manufactured as a single unit.

22. An apparatus according to claim 1, wherein said base is manufactured using at least one technique selected from the group consisting of injection molding, transfer molding, blow molding, rotational molding, thermoforming, structural foam molding, and compression molding.

23. An apparatus according to claim 1, wherein said perimeter of said base has a shape selected from the group consisting of generally teardrop, generally ovate, and generally oval.

24. An apparatus according to claim 1, wherein a first height of an upwardly facing surface of said platform is less than a second height of an upwardly extending surface of said exterior wall.

25. An apparatus according to claim 1, wherein at least one of the group consisting of an inwardly facing surface of said exterior wall, an outwardly facing surface of said platform, and combinations thereof is tapered to facilitate drainage to said canal.

26. An apparatus according to claim 1, wherein an upwardly facing surface of said platform is convex.
