Description
Background of the Invention
[0002] Water pool apparatuses, such as portable spas, portable pools, in-ground spas, in-ground pools, hot tubs and recirculating bath tubs are enormously popular. Most such water pool apparatuses have a water recirculation system wherein water within a main water basin is recirculated through a filter, a heater and then back into the main water basin by a centrifugal pump.
[0003] The water recirculation system is typically controlled by a controller disposed within a controller housing. In most modern water pool apparatuses, the controller is a solid state electronic controller comprising an electrical circuit board having a large number of related electrical wiring connections.
[0004] A problem arises when the electrical circuit board of the controller wears out or otherwise fails. Replacing the electrical circuit board and reconnecting all of the related electrical wires to the electrical circuit board is awkward, time-consuming and requires the employment of a trained technician. This makes replacement of the electrical circuit board arduous and expensive.

Detailed Description
[0013] The following discussion describes in detail one embodiment of the invention and several variations of that embodiment. This discussion should not be construed, however, as limiting the invention to those particular embodiments. Practitioners skilled in the art will recognize numerous other embodiments as well.
[0014] The invention is a controller housing 10 for housing a controller 12, such as a controller used to control a water pool apparatus. The controller housing 10 comprises a first box 14 and a second box 16.
[0015] The first box 14 defines a first enclosure 18. The first box 14 has a plurality of walls 20. In a typical embodiment, such as that which is illustrated in the drawings, the first box 14 has six rectangular walls 20, each wall 20 being attached at right angles to each adjacent wall 20. In the embodiment illustrated in the drawings, the first box 14 has two opposed parallel side walls 20a, two opposed end walls 20b, a top wall 20cand a bottom wall 20d.
[0016] Disposed within the first box 14 may be an electrical heater 22, such as an XL heater exchanger, having opposed fluid connection ends 24. The heater 22 includes a pressure switch 25 to detect the flow of water through the heater 22 and to thereafter activate the heater 22. In operation, the spa heater 22 is disposed in fluid tight communication with the recirculating spa water, such that recirculating water discharged from a centrifugal pump flows through the heater 22 and then back into the main basin of the water pool apparatus. Within the heater 22, the recirculating water is heated as necessary to maintain a predetermined spa water temperature.
[0017] Also within the first box 14 are various electrical connections (not shown), including electrical conductors connected to a source of electrical power for driving the electrical heater 22 and for powering the controller 12.
[0018] In the embodiment illustrated in the drawings, the first box 14 has an exterior side wall 20aand an interior side wall 20a. The interior side wall 20aforms a connection wall 26 for the first box 14. The connection wall 26 has an interior surface (not shown) and an exterior surface 28.
[0019] Disposed within the connection wall 26 of the first box 14 are one or more first moieties 30 of electrical connectors. Each first moiety 30 is of the type which can be connected to a corresponding second moiety 32 by pressing the first moiety 30 towards the second moiety 32. Typically, each first moiety 30 is either a male electrical connector or a female electrical connector. In the embodiment illustrated in the drawings, the connection wall 26 of the first box 14 has three first moieties 30, each first moiety 30 being a female electrical connector. The first moieties 30 are rigidly disposed on the exterior surface 28 of the connection wall 26. Each of the first moieties 30 are electrically connected to the interior of the first enclosure 18. In a typical embodiment, one or more of the first moieties 30 are high voltage first moieties 30awhich cooperate with corresponding high voltage second moieties 32a. Each of the high voltage first moieties 30aare connected to a source of electrical power via electrical connectors (not shown) disposed within the first enclosure 18. One or more of the first moieties 30 are low voltage first moieties 30bwhich cooperate with corresponding low voltage second moieties 32b. The low voltage first moieties 30bare electrically connected to various spa sensors.
[0020] The second box 16 defines a second enclosure 34. Like the first box 14, the second box 16 has a plurality of walls 36. In a typical embodiment, such as that which is illustrated in the drawings, the second box 16 has six rectangular walls 36, each wall 36 being attached at right angles to each adjacent wall 36. Also in the embodiment illustrated in the drawings, the second box 16 has two opposed parallel sidewalls 36a, two opposed end walls 36b, a top wall 36cand a bottom wall 36d.
[0021] Disposed within the second box 16 is the electrical controller 12 comprising an electrical circuit board 38. The electrical controller 12 can be used to control the various operating equipment which make up the water pool apparatus, including the recirculation pump and the electrical heater 22. The controller 12 is connectable to control signal wires (not shown) from the various water pool apparatus equipment and operating monitors via a plurality of electrical connection receptacles 40 and a control panel phone jack connection 41 disposed in one or more of the walls 36 of the second box 16. In the embodiment illustrated in the drawings, eight female electrical connection receptacles 40 are disposed in one of the two opposed end walls 36bof the second box 16. Each of these electrical connection receptacles 40 is connected to the circuit board 38 by connection wires 42 as illustrated in FIG. 5.
[0022] In the embodiment illustrated in the drawings, the second box 16 has an exterior side wall 36aand an interior side wall 36a. The interior side wall 36aforms a connection wall 44 for the second box 16. The connection wall 44 of the second box 16 has an interior surface (not shown) and an exterior surface 46.
[0023] Rigidly disposed within the connection wall 44 of the second box 16 are one or more second moieties 32 of electrical connectors. Each second moiety 32 is of the type which can be connected to a corresponding first moiety 30 disposed in the connection wall 26 of the first box 14. Typically, each second moiety 32 is either a male electrical connector or a female electrical connector. In the embodiment illustrated in the drawings, the connection wall 44 of the second box 16 has three second moieties 32, each second moiety 32 being a male electrical connector. Each of the three second moieties 32 are aligned with one of the three first moieties 30 in the connection wall 26 of the first box 14, so that each second moiety 32 can be operatively connected to a corresponding first moiety 30 by pressing the connection wall 26 of the first box 14 towards the connection wall 44 of the second box 16. In this manner, the electrical circuit board 38 disposed within the second box 16 is electrically connected to the first enclosure 18.
[0024] In the embodiment illustrated in the drawings, the two side walls 20aof the first box 14 are essentially the same shape and dimensions as the side walls 36aof the second box 16. By this construction, when the second box 16 is disposed in abutment with the first box 14, the top walls 20band 36bof the two boxes 14 and 16 are disposed in a single horizontal plane and each of the two opposed end walls 20band 36bof the two boxes 14 and 16 are disposed in single vertical planes. This gives the controller housing 10 a compact and aesthetically pleasing appearance.
[0025] In the embodiment illustrated in the drawings, the second box 16 is attached to the first box 14 by a pair of disengageable hinges 48. Each hinge 48 is comprised of a male moiety 50 and a female moiety 52. Each hinge 48 is readily disengageable by sliding the male moiety 40 laterally away from the female moiety 52. Conversely, each hinge 48 is readily reengageable by sliding the male moiety 50 back into the female moiety 52. By attaching the second box 16 to the first box 14 using hinges 48, the second moieties 32 of electrical connectors disposed in the connection wall 44 of the second box 16 can be precisely aligned with the first moieties 30 of the electrical connectors disposed within the connection wall 26 of the first box 14, so that rotating the second box 16 towards the first box 14 about the male moieties 50 of the hinges 48 automatically engages the first moieties 30 of the electrical connectors with the second moieties 32. Conversely, when the second box 16 is rotated away from the first box 14 about the male moieties 50 of the hinges 48, the first moieties 30 of the electrical connectors are automatically disengaged from the second moieties 32 of the electrical connectors.
[0026] Optionally, a pair of retainer connectors 54 are aligned on each of the two boxes 14 and 16 so as to firmly retain the second box 16 against the first box 14 during normal operation. In the embodiment illustrated in the drawings, the retainer connectors 54 are a pair of apertured clips which can be firmly retained to one another by a bolt and nut connection.
[0027] In the design of the invention, the awkwardness, complexity and expense of replacing a failed circuit board 38 within the controller 10 is eliminated. When the circuit board 38 fails, it is replaced with a new circuit board 38 by replacing the entirety of the second box 16. This operation can be simply and quickly accomplished by the owner of the water pool apparatus, without having to hire a trained technician. The user merely disconnects the retainer connectors 54 and swings the second box 16 away from the first box 14 as illustrated in FIG. 3. Next, the user disengages the second box 16 from the first box 14 by sliding the male moieties 50 of the disengageable hinges 48 away from the corresponding female moieties 52, as illustrated in FIG. 4. The user then connects a new second box 16 to the first box 14 by sliding the male moieties 50 of the disengageable hinges 48 into the female moieties 52, rotating the second box 16 towards the first box 14 so as to engage the first moieties 30 of the electrical connectors to the second moieties 32 of the electrical connectors and reconnecting the retainer connectors 54. The entire operation can be accomplished in a matter of seconds. Unlike replacement of circuit boards within control boxes of the prior art, neither the user nor his or her hired technician needs to disconnect and reconnect the many internal connection wires 42 of the electrical circuit board 38. The invention therefore saves the user of the water pool apparatus considerable effort, down time and expense.
[0028] Having thus described the invention, it should be apparent that numerous structural modifications and adaptations may be resorted to without departing from the scope and fair meaning of the instant invention as set forth hereinabove and as described hereinbelow by the claims.
