Description




BACKGROUND OF THE INVENTION




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.




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.




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.




Accordingly, there is a need for a water pool apparatus controller and controller housing which avoids the aforementioned problems in the prior art in an efficient and cost-effective manner.

. The connection wall


44


of the second box


16


has an interior surface (not shown) and an exterior surface


46


.




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

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


.




In the embodiment illustrated in the drawings, the two side walls


20




a


of the first box


14


are essentially the same shape and dimensions as the side walls


36




a


of the second box


16


. By this construction, when the second box


16


is disposed in abutment with the first box


14


, the top walls


20




b


and


36




b


of the two boxes


14


and


16


are disposed in a single horizontal plane and each of the two opposed end walls


20




b


and


36




b


of the two boxes


14


and


16


are disposed in single vertical planes. This gives the controller housing


10


a compact and aesthetically pleasing appearance.




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.




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.




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.




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.
