Benefits of technology
[0008]The present invention is directed to a device for protectively shielding the fan opening on the top of an outdoor air conditioner/heat pump condenser unit includes a dome-shaped cover that is sized to completely cover the fan opening. A bottom annular rim of the cover has a gasket that seals against the top surface of the condenser unit when the cover is lowered. An arrangement of vertical guide posts positioned about the fan opening on the top of the condenser unit guides movement of the cover through a rising and lowering movement. Specifically, the vertical guide posts each extend through an opening formed through a tab/ear extending from a respective one of several L-shaped outside brackets on the cover, wherein each L-shaped bracket is positioned for corresponding alignment with one of the vertical guide posts. When the condenser fan motor is not operating, the cover is normally lowered with the gasket seated against the top surface of the condenser unit to prevent entry of rain, sprinkler water, leaves, dirt and other debris into the condenser unit housing. Upon operation of the condenser fan motor, the cover rises vertically, on the guide posts, to allow escape o
Problems solved by technology
However, the escape of water is eventually obstructed as a result of accumulating debris within the condenser unit housing.
Specifically, leaves, dirt and other debris that accumulate within the condenser unit trap water that eventually leads to rusting and deterioration of the bottom floor of the condenser unit housing.
Moreover, unwanted en

Embodiment Construction
[0016]Referring to the several views of the drawings, and initially FIGS. 1 and 2, the weather guard device of the present invention is shown and is generally indicated as 10. The weather guard device 10 is specifically structured for protectively shielding a fan opening 120 on the top 110 of an outdoor HVAC condenser unit 100 (see FIG. 1). The fan opening 120 on the top of the condenser unit housing is typically covered with a wire screen or grating to prevent contact with the rotating fan blade and potential bodily injury.
[0017]The weather guard apparatus 10 includes an arrangement of vertical guide posts 20 that are fitted to the top 110 of the condenser unit 100, as seen in FIGS. 1-3. Specifically, a bottom end of each guide post 20 is threaded (not shown) for screw threaded attachment within a threaded hole in a mounting plate 30. Each mounting plate 30 corresponding to one of the several vertical guide posts 20 is fastened to the top 110 of the condenser unit 100 with the use ...

An apparatus for protectively shielding the fan opening on the top of an outdoor air conditioner/heat pump condenser unit includes a dome-shaped cover that is sized to completely cover the fan opening. An arrangement of vertical guide posts positioned about the fan opening on the top of the condenser unit guides movement of the cover through a rising and lowering movement. When the condenser fan motor is not operating, the cover is seated against the top surface of the condenser unit to prevent entry of rain, sprinkler water, leaves, dirt and other debris into the condenser unit housing. Upon operation of the condenser fan motor, the cover rises vertically, on the guide posts, to allow escape of forced airflow in a radially outward flow between the cover and the top of the condenser unit, while still shielding the fan opening from falling rain and leaves.
Description
[0001]This non-provisional patent application is based on provisional patent application Ser. No. 62 / 217,486 filed on Sep. 11, 2015.BACKGROUND OF THE INVENTION[0002]Field of the Invention[0003]The present invention is directed to a device for protectively shielding the condenser fan opening on the top of a condenser unit in an air conditioning or heat pump system to prevent unwanted entry of water, leaves, dirt and other debris into the condenser unit housing.[0004]Discussion of the Related Art[0005]Air conditioning and heat pump systems typically have a condenser unit that is placed outdoors, either on a slab next to a residential dwelling or on the rooftop of a commercial building. The condenser unit contains a compressor, coils that surround the compressor and a fan and fan motor assembly above the compressor. These components are contained within a housing that typically has a bottom or floor, four sides and a top. The top of the condenser unit housing has an opening that is usu...
