1. Field of the Invention
The present invention relates to a portable generator and more specifically to a weather resistant portable generator with an integrated remote electrical distribution panel.
2. Description of Related Art
Electrical generators are commonly used to provide electrical power in situations where conventional wired electrical power grid sources are not available, such as during a power outage, at construction sites, or at remote locations. The generator may use an engine to drive the generator. The generator may have power outlets located on the generator itself.
Typically, portable electric generators are operated outdoors due to the fumes which are a byproduct of the gasoline engine that is running while the portable generator is generating electricity. While outside, the portable electric generator is subject to the weather conditions. If a portable electric generator is in operation while it is raining, significant electrocution hazards may exist. This may be due to improper grounding, exposed wiring or the like.
Another drawback with many conventional portable electric generators is the lack of an integrated remote GFCI (Ground Fault Circuit Interrupt) outlet. A GFCI outlet is designed to provide extra protection for wet areas. A GFCI circuit measures the flow of electricity in both the hot and neutral wires. If the two are not equal, then there is electricity flowing somewhere else out of the circuit and the breaker disconnects the power.
The present invention provides a portable electric generator that is operable in wet conditions. Additional embodiments of the present invention present a means for distributing the electrical power and more specifically GFCI power generated by the portable electric generator via an integrated remote power distribution panel.
A weather resistant portable electric generator is disclosed. The weather resistant portable electric generator has a fuel tank which provides fuel to an engine. The engine is connected to an alternator, which is connected to an outlet, the outlet configured to receive an electrical connector. The weather resistant portable electric generator also has a control panel and a moveable cover. The moveable cover can move between a raised and a lowered position. The control panel is located under the moveable cover. When the moveable cover is in the closed position, the moveable cover protects the control panel and outlet from atmospheric conditions.

The term “another”, as used herein, is defined as at least a second or more. The terms “including” and/or “having”, as used herein, are defined as comprising (i.e., open language). The term “coupled”, as used herein, is defined as connected, although not necessarily directly, and not necessarily mechanically.
Reference throughout this document to “one embodiment”, “certain embodiments”, and “an embodiment” or similar terms means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of such phrases or in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments without limitation.
The term “or” as used herein is to be interpreted as an inclusive or meaning any one or any combination. Therefore, “A, B or C” means any of the following: “A; B; C; A and B; A and C; B and C; A, B and C”. An exception to this definition will occur only when a combination of elements, functions, steps or acts are in some way inherently mutually exclusive.
The drawings featured in the figures are for the purpose of illustrating certain convenient embodiments of the present invention, and are not to be considered as limitation thereto. Term “means” preceding a present participle of an operation indicates a desired function for which there is one or more embodiments, i.e., one or more methods, devices, or apparatuses for achieving the desired function and that one skilled in the art could select from these or their equivalent in view of the disclosure herein and use of the term “means” is not intended to be limiting.
As those skilled in the art may appreciate, when the generator 100 is running, fuel is flowing into the engine from the fuel tank 120. The engine in turn is operating an alternator, which in turn, is generating electricity. As part of the operational process, the generator converts mechanical energy into electrical energy. The electrical energy is then provided as power to the operator.

The length of the cord 116 may vary. In one embodiment the length of cord may be 25 feet. In another embodiment, the length of cable may be 50 feet. When the power panel 106 is positioned on the hook 104 of the generator 100, the cord 116 may be wound around the power panel 106 to allow less clutter. In order to have longer cable lengths, the power panel 106 may need to be larger in circumference to accommodate the winding of the longer cable.
Located under the cover 102 may be a control panel which may consist of various control components as well as outlet 172. In the closed position, the cover 102 may provide protection from adverse weather conditions which may include, but not limited to, rain, sleet, snow and the like. The cover 102 may also have side panels 103 which may also facilitate the protection of the various components under the cover 102.
A cover 102 provisioned with a notch 107 allows the cover 102 to close more completely when the power panel 106 is hanging on the hook 104 and is connected to the generator 100. In this embodiment, the cover 102 may still come in contact with the cord 116, but the cover 102 may close almost to a fully closed position when the cord 116 is routed through the notch 107.

Similar to the surfaces of the fuel tank 120, the surfaces that the various components may be mounted upon may also be angled in order to facilitate the flow of water off the generator 100. For example, the surface that the outlet 172 is positioned on is angled away from the cover 102. The surface is angled in this manner so any water that comes in contact above the outlet 172, would drip away from the edge of the surface and not drip on the outlet 172. Directing water away from the electrical components may provide additional safeguards for the operator. Water may gather on these surfaces should the cover 102 be opened while the generator was operating in inclement conditions.
Certain other weather resistant characteristics may be applied to the generator 100. For example, in one embodiment of the present invention, the cover 102 may be clear. A clear cover would allow the operator to view the display 115 or view the condition of the breaker 111 when the cover 102 is in the closed position. Keeping the cover 102 in the closed position during inclement weather conditions may provide protection to the components. Other weather resistant characteristics of the present invention may include a display 115 that is sealed such that it may be impervious to water. The same weather resistant concept may be applied to the control switch 113. The control switch 113 may be moved from one position to another within a sealed environment. Additional weather resistant concepts are described in greater detail in subsequent sections.
To facilitate the hanging of the power panel 106 on the hook 104, a handle opening 135 or other type of opening may be implemented. The handle opening 135 may also provide an easy way for the operator to remove the power panel 102 from the hook 104 and carry it to a remote location. Locating the power panel 102 away from the generator 100 may allow the operator to operate the generator 100 outside in the weather elements while providing GFCI power into an interior of a home. The use of GFCI circuitry allows the manufacturer to provide an additional level of operator protection while providing reliable remote power.
As those skilled in the art may appreciate, A GFCI outlet is a device that adds a greater level of safety by reducing the risk of electric shock. Most building codes may require that a GFCI outlet be used in wet locations such as bathrooms, kitchens, laundry rooms and outdoors. A GFCI outlet monitors for a current imbalance between the hot and neutral wires and breaks the circuit if that condition occurs. A circuit breaker usually may trip if a short is experienced, but it may not act fast enough to protect the operator from harm. A GFCI outlet is more sensitive and acts faster than a circuit breaker or fuse and is thus an important safety feature.
In one embodiment the display 715 may be a simple alpha numeric display. In another embodiment, the display 715 may be an LCD display. An LCD display may be able to provide the operator additional information such as, but not limited to, graphical representations of the amount of fuel remaining, hours the generator 700 had been running, amount of power generated, oil replacement schedule, and the like.

The power panel 706 is connected to the generator 700 via electrical cord 716. In one embodiment, the electrical cord 716 may be routed through a notch 707 and connected to an outlet 772 on the generator 700. The length of the cord 716 may vary. In one embodiment, the length of cord may be 25 feet. In another embodiment, the length of cord may be 50 feet. When the power panel 706 is positioned on the generator 700, the cord 716 may be wound around the power panel 706 to allow less clutter. In order to have longer cable lengths, the power panel 706 may need to be larger in circumference to accommodate the winding of the longer cable.
Although specific embodiments have been illustrated and described herein, those of ordinary skill in the art appreciate that any arrangement, which is calculated to achieve the same purpose, may be substituted for the specific embodiments shown and that the invention has other applications in other environments.
