DETAILED DESCRIPTION

When introducing elements of various embodiments of the present disclosure, the articles “a,” “an,” and “the” are intended to mean that there are one or more of the elements. The terms “comprising,” “including,” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements. Additionally, it should be understood that references to “one embodiment” or “an embodiment” of the present disclosure are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features.

One or more specific embodiments will be described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

The present disclosure is directed to an enclosure (e.g., electrical box assembly) for electrical components (e.g., control components) of a heating, ventilation, and/or air conditioning (HVAC) system. For example, the enclosure may include an electrical box and an access panel or cover that when coupled to the electrical box encloses the electrical components within the electrical box. The cover may be removable to provide greater access to the electrical components within the electrical box (e.g., during servicing).

The configuration of the enclosure may vary based on the location of the enclosure. In addition, the number of components to couple and/or secure the cover to the electrical box are minimal compared to typical enclosures for electrical components. For example, in certain embodiments, the electrical box includes one or more slots to receive the cover. In certain embodiments, a bottom wall extending from a back wall of the electrical box may include one or more slots to receive one or more respective tabs extending from the cover. In other embodiments, side walls extending from the back wall of the electrical box may include bent extensions that define slots to receive the cover. The cover may also include a lip that partially extends over a portion of a top wall extending from the back wall of the electrical box. The cover may be secured to the electrical box via a fastener (e.g., knob, screw, latch, etc.) that extends through both the lip of the cover and the top wall of the electrical box. The utilization of fewer components to secure the cover to the electrical box enables rapid coupling or removal of the cover from the electrical box. In addition, the utilization of fewer components reduces the cost of manufacturing the enclosure.

Turning now to the drawings, FIGS. 1-3 illustrate an embodiment of an enclosure 10 for electrical components of a HVAC system. The enclosure 10 includes an electrical box 12 and an access panel or cover 14. In certain embodiments, the electrical box 12 and the cover 14 may be made of a metal (e.g., sheet metal).

The cover 14 includes the wall 34 and the lip 36. The lip 36 extends from the edge 46 (e.g., top edge) that extends between the edges 40, 42. The lip 36 may extend along an entire length of the edge 46 or only a portion of the length of the edge 46. The lip 36 extends in the direction 48 from surface 50 (e.g., outer surface) to surface 52 (e.g., inner surface) of the wall 34. When the cover 14 is coupled or secured to the electrical box 12, the lip 36 only partially extends over the outer surface 44 of the wall 22. In certain embodiments, the lip 36 may extend over the entire outer surface 44 of the wall 22.

The wall 24 includes one or more slots 80 adjacent the open front 17. The number of slots 80 may vary (e.g., 1, 2, 3, 4, 5, or more slots 80). A length 82 of the slots 80 may vary between electrical boxes 12 or within the same electrical box. A location of the slots 80 may vary. For example, in certain embodiments, one or more slots 80 may be adjacent the side walls 26, 28. In other embodiments, one or more slots 80 may be centrally located between the side walls 26, 28. As depicted in FIG. 10, the wall 24 include two slots 84, 86. The slot 84 is more adjacent to the wall 26, while the slot 86 is more adjacent to the wall 28.

The wall 34 of the cover 14 includes one or more tabs 88 (e.g., protrusions) extending away from an edge 90 (e.g., bottom edge) of the wall 34 in the direction 38. The tabs 88 are configured to be inserted (e.g., in the direction 38) within the slots 80 on the wall 24 when the cover 14 is coupled to or secured to the electrical box 10. The number of tabs 88 may vary (e.g., 1, 2, 3, 4, 5, or more tabs 88). The number of tabs 88 corresponds to the number of slots 80. A length 92 of the tabs 88 may vary between electrical boxes 12 or within the same electrical box. The length of each tab 88 is less than the length 82 of the respective slot 80 that the tab 88 is inserted into when coupling the cover 14 to the electrical box 12. A location of tabs 88 may vary. For example, in certain embodiments, one or more tabs 88 may be adjacent the edges 40, 42. In other embodiments, one or more tabs 88 may be centrally located between the edges 40, 42. As depicted in FIG. 11, the wall 34 include two tabs 94, 96. The tab 94 is more adjacent to the edge 40, while the tab 96 is more adjacent to the edge 42.

The wall 34 of the cover 14 also includes lips 98, 100. Lips 98, 100 extend from the respective edges 40, 42. The lips 98, 100 may extend along an entire length of the respective edges 40, 42 or only a portion of the length of the respective edges 40, 42. The lips 98, 100 extend in the direction 48 from surface 50 (e.g., outer surface) to surface 52 (e.g., inner surface) of the wall 34. When the cover 14 is coupled or secured to the electrical box 12, the lips 98, 100 only partially extend over respective outer surfaces 102, 104 of the walls 26, 28. In certain embodiments, the lips 98, 100 may extend over the entire respective outer surfaces 102, 104 of the walls 26, 28.

The wall 22 includes the opening 54 adjacent the open front 17 of the electrical box 12.

The enclosure of the present disclosure may provide one or more technical effects useful in the enclosing of electrical components of a HVAC system. For example, the enclosure may include an electrical box that is coupled to a removable cover. Removal of the cover provides more space and access to the electrical components within the electrical box. In addition, the enclosure includes fewer components to enable the enclosure of the electrical components. In addition, the number of components to couple and/or secure the cover to the electrical box are minimal compared to typical enclosures for electrical components. For example, in certain embodiments, the electrical box includes one or more slots to receive the cover. In certain embodiments, a bottom wall extending from a back wall of the electrical box may include one or more slots to receive one or more respective tabs extending from the cover. In other embodiments, side walls extending from the back wall of the electrical box may include bent extensions that define slots to receive the cover. The cover may also include a lip that partially extends over a portion of a top wall extending from the back wall of the electrical box. The cover may be secured to the electrical box via a fastener (e.g., knob, screw, latch, etc.) that extends through both the lip of the cover and the top wall of the electrical box. The utilization of fewer components to secure the cover to the electrical box enables rapid coupling or removal of the cover from the electrical box. In addition, the utilization of fewer components reduces the cost of manufacturing the enclosure. The technical effects and technical problems in the specification are examples and are not limiting. It should be noted that the embodiments described in the specification may have other technical effects and can solve other technical problems.

While only certain features and embodiments of the disclosure have been illustrated and described, many modifications and changes may occur to those skilled in the art, such as variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, including temperatures and pressures, mounting arrangements, use of materials, colors, orientations, and so forth without materially departing from the novel teachings and advantages of the subject matter recited in the claims. The order or sequence of any process or method steps may be varied or re-sequenced according to alternative embodiments. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the disclosure. Furthermore, in an effort to provide a concise description of the exemplary embodiments, all features of an actual implementation may not have been described, such as those unrelated to the presently contemplated best mode of carrying out the disclosure, or those unrelated to enabling the claimed disclosure. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation specific decisions may be made. Such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure, without undue experimentation.
