This invention relates to a line components duct system for enclosing refrigeration lines, electrical wires, and condensate tubes for a heating and cooling air conditioning system, and more particularly relates to a universal line components duct elbow for enclosing the line components and variety of condensate tanks.
In a heating and cooling air conditioning system, such as a ductless mini split heating and cooling air conditioning system, refrigeration lines and electrical wires run between an evaporator unit located inside a building and a condenser unit located outside the building. The heating and cooling air conditioning system may also include condensate tubes that run from the evaporator to a condensate tank, from the condensate tank to a condensate pump, and from the condensate pump to a drain inside the building or to a location outside the building. The refrigeration lines, condensate tubes, and electrical wires will be collectively referred to hereinafter as line components. In order to keep the line components organized and out of sight, an enclosed line components duct system or trunk houses the line components. The line components duct system is used inside the building to enclose the line components between the evaporator and a point of penetration to the outside of the building in the circumstances where the line components cannot be embedded in a wall such as is the case with older plaster construction. In addition, the line components duct system is used outside the building between the wall penetration point from the interior of the building and the condenser unit. The line components duct system is particularly useful when a building is retrofit with the ductless mini split heating and cooling air conditioning system with the evaporator unit attached to a wall adjacent the ceiling of a room within the building. In such a case, the line components duct system typically runs from the mini split evaporator unit mounted on the interior wall to the ceiling along the interior wall.
DiversiTech Corporation, the assignee of the present invention and application, sells a line components duct system under the mark SpeediChannel. Such a line components duct system includes a straight section line components duct having a rectangular cross-section. The straight section line components duct comprises an elongated base with an attached side wall and a snap on cover with an attached side wall. The cover with its attached side wall snaps onto the base with its attached side wall to complete the enclosure of the straight section line components duct. An integral channel with a series of channel clips runs along the length of the elongated base. The channel clips engage the integral channel and are slidable along the length of the integral channel. The channel clips secure the line components to the base of the line components duct in order to keep the line components from shifting or vibrating. The line components duct system also includes various fittings to accommodate turns in the direction of the line components, to accommodate penetration of the internal and external walls of the building, and to accommodate attachment of the line components duct to the condenser unit and the evaporator unit.
In a typical installation for a ductless mini split heating and cooling air conditioning system, the base of the line components duct is attached to a mounting surface such as the internal wall of the room of the building. The line components are positioned on the base and secured with the channel clips. The cover with its attached wall is then snapped onto the base with its attached wall to complete the enclosure, to protect the line components, and to hide the line components from view.
In installations of the mini split heating and cooling air conditioning system, a condensate tank is required to collect condensate produced by the evaporator unit. A condensate pump is then mounted at a remote location to draw the condensate from the condensate tank and pump the condensate to either a drain inside the building or to a remote location outside the building. The condensate tank is typically located closely adjacent the evaporator unit. In that regard, the condensate tank is often located in a line components duct elbow where the condensate line and the rest of the line components exit the evaporator unit and then make a 90° turn toward the ceiling of the room. The condensate pump is usually located above the ceiling and draws the condensate from the condensate tank through the condensate tube in the line components duct.
A number of manufacturers offer a condensate tank and associated condensate pump. The condensate tanks are offered in a variety of sizes and shapes. Consequently, an installer must stock a variety of line components duct elbows in order to accommodate the variety of sizes and shapes of the various condensate tanks.
The present invention addresses the problem associated with the need of the installer to stock a variety of line components duct elbows by providing a universal line components duct elbow (universal elbow) that will accommodate a variety of condensate tanks. Particularly, the universal elbow includes an elbow base, with a bottom wall and sidewalls, an elbow cover, and an interface clip releasably connected to the bottom wall and the sidewall of the elbow base and adapted for supporting a condensate tank within the universal elbow. In order to releasably connect the interface clip to the bottom wall and the sidewall of the elbow base, the bottom wall and sidewall of the elbow base include an elbow base/clip securing structure that engages a complementary clip/elbow base securing structure on one side of the interface clip. In order to secure the condensate tank within the universal elbow, the interface clip has a clip/tank securing structure on the opposite side of the interface clip that engages the unique structure of each of the condensate tanks that are available.
In order to accommodate a variety of differently shaped condensate tanks, the installer only needs to stock a variety of smaller interface clips that are connected to the bottom wall and the sidewall of the elbow base and which have a variety of different clip/tank securing structures each of which is specifically configured to match the size and structure of a particular commercially available condensate tank.
Further objects, features and advantages will become apparent upon consideration of the following detailed description of the invention when taken in conjunction with the drawings and the appended claims.

The interface clip 148 is mounted to the elbow base 32, by aligning the elongated groove 164 of the interface clip 148 with one of the elongated tracks 52b and pushing the interface clip 148 toward the bottom wall 34 of the elbow base 32 along the elongated track 52b. Upon reaching the elbow base hook 56b, the clip shoulder 166b engages the hook camming surface 58 of the elbow hook 56b. Further movement of the interface clip 148 toward the bottom wall 34 of the elbow base 32 causes clip shoulder 166b to engage the camming surface 58 and deflect the elbow base hook 56b to allow the clip shoulder 166b to seat against the bottom wall 34 and behind the hook retaining surface 60 of the base hook 56b. The combination of the elongated tracks 52b and the base hook 56b holds the interface clip 48 in place. The interface clip 148 can be removed by manually deflecting the base hook 56b to disengage the clip shoulder 166b thereby allowing the interface clip 148 to move away from the bottom wall 34 of the elbow base 32 and out of engagement with the elongated track 52b.

Upon reaching the elbow hook 56b, the clip shoulder 266 engages the hook camming surface 58 of the elbow hook 56b. Further movement of the interface clip 248 toward the bottom wall 34 of the elbow base 32 causes clip shoulder 266 to engage the camming surface 58 and deflect the base hook 56b to allow the clip shoulder 266 to seat against the bottom wall 34 and behind the hook retaining surface 60 of the base hook 56b. The combination of the elongated tracks 52b and the base hook 56b holds the interface clip 48 in place. The interface clip 248 can be removed by manually deflecting the base hook 56b to disengage the clip shoulder 266 thereby allowing the interface clip 248 to move away from the bottom wall 34 of the elbow base 32 and out of engagement with the elongated track 52b.
