Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an attic ventilation system and, more particularly, to an attic ventilation system that includes a solar powered fan and a solar panel that can be located instead of a front window of a roof.

2. Description of the Related Art

Several designs for attic ventilation systems have been designed in the past. None of them, however, include an attic ventilation system that can supply the attic with fresh air from outside.

Applicant believes that a related reference corresponds to U.S. Pat. No. 9,582,011 issued for an integrated attic ventilation. Applicant believes that another related reference corresponds to U.S. Pat. No. 8,915,778 issued for a hybrid solar attic vent comprising a housing configured to be mounted on the roof or in the gable of a building in communication with the attic of the building, wherein a photovoltaic solar panel is positioned to be exposed to sunlight and to power the attic fan when sufficient sunlight is present. However, none of them include a system comprising a solar panel and solar power fan that can be mounted instead of a glass window of an attic, bringing fresh air from outside to the attic.

Other documents describing the closest subject matter provide for a number of more or less complicated features that fail to solve the problem in an efficient and economical way. None of these patents suggest the novel features of the present invention.

SUMMARY OF THE INVENTION

It is one of the objects of the present invention to provide a system comprising a solar panel and a powered-solar fan to refresh an attic during the day.

It is another object of this invention to provide a ventilation system that can supply fresh air from outside to an attic, expelling the hot air from inside the attic to outside.

It is still another object of the present invention to provide a system that can refresh an attic saving on the energy bills, since the solar-powered fan only would work on hot days, when there is sun to power the fan.

It is yet another object of this invention to provide such a device that is inexpensive to implement and maintain while retaining its effectiveness.

Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

Referring now to the drawings, where the present invention is generally referred to with numeral 10, it can be observed that it basically includes a fan assembly 20, a power source assembly 40 and an attic assembly 60. It should be understood there are modifications and variations of the invention that are too numerous to be listed but that all fit within the scope of the invention. Also, singular words should be read as plural and vice versa and masculine as feminine and vice versa, where appropriate, and alternative embodiments do not necessarily imply that the two are mutually exclusive.

The fan assembly 20 includes fan blades 22 connected to a shaft 24b of a motor 24. Best observed in FIG. 4, each of the fan blades 22 includes a blade proximal end and a blade distal end. Each of the fan blades 22 have an elongated shape. The blade distal and may have a width less than width of the blade proximal end. Each of the fan blades 22 may have the same length. The fan blades 22 may be made of plastic, metal, carbon fibers or any other rigid material. The fan assembly also may include a fan housing 24 to protect the fan blades 22. The fan housing 24 may have a circular shape. In a preferred embodiment, the fan housing 24 may be made of metal. It also may be suitable for the fan housing to be made of wood, plastic, carbon fibers or any other material with high resistance and strength. The fan housing 24 may be mounted to a window frame 62 of the attic assembly 60 by support bars 26. Each of the support bars 26 may have substantially the same length. The support bars 26 may have a cylindrical shape. Other embodiments for the support bars 26 may include a rectangular shape, a beam shape or any other shape. In a preferred embodiment, the support bars 26 may be made of metal. The support bars 26 may have a coating to avoid corrosion. A first distal end of each of the support bars 26 may be connected to an external surface of the fan housing 24 by welding. It also may be suitable to connect the first distal end of each of the support bars 26 to the fan housing 24 by bolts, rivets or the like. A second distal end of each of the support bars 26 may be connected to an interior surface of the window frame 62 by welding. It also may be suitable to connect the second distal end of each of the support bars 26 to the window frame 62 by bolts, rivets or the like. In a preferred embodiment, the window frame 62 may have a squared shape. It also may be suitable for the window frame 62 to have a circular, triangular, oval or any other shape. The perimeter of the window frame 62 may be greater than the perimeter of the fan housing 24. The window frame 62 may be made of metal, carbon fibers, plastic, wood or any other material with high strength and resistance.

As it can be observed in FIG. 3, a shaft 28a may transmit movement from a motor 28 to the fan blades 22. The shaft 28a may be made of metal. The motor 28 may be an electric motor of direct current. The motor 28 may include a motor housing 28b. The motor housing 28 may be attached to the fan housing 24 by welding. It also may be suitable to attach the motor housing 28 to the fan housing 24 by bolts, rivets or the like.

The power source assembly 40 may include a solar panel 42. The solar panel 42 may have a squared shape. It also may be suitable for the solar panel to have a triangular, circular, oval or any other shape. The solar panel 42 may transform solar energy to electric energy. The solar panel 42 may be connected to a voltage regulator 48 to regulate the current and avoid energy fluctuations. The voltage regulator 48 may be connected to the motor 28 to supply the electric energy to rotate the fan blades 22 of the fan assembly 20. The solar panel 42 may be attached to a support frame 44. The support frame 44 may have a squared shape. It also may be suitable for the support frame 44 to have a circular, triangular or any other shape. Length and width of the support frame 44 may be greater than length and width of the solar panel 42. The support frame 44 may be made of metal, wood, carbon fibers or any other material with high strength. It may be suitable for the support frame 44 to have a coating to avoid corrosion.

The support frame 44 may be attached to the window frame by top support bars 46 and bottom support bars 46a. The top support bars 46 and bottom support bars 46a may have a circular, rectangular or any other shape. In a preferred embodiment, the top support bars 46 and bottom support bars 46a may be of metal. In other embodiments, the top support bars 46 and bottom support bars 46a may be made of wood, carbon fibers or any other material with high strength. It may be suitable for the top support bars 46 and bottom support bars 46a to have a coating. The bottom support bars 46a may have a larger length than the top support bars 46. A first distal end of each of the bottom support bars 46a may be welded to bottom corners of the support frame 44. A second distal end of each of the bottom support bars 46a may be welded to bottom corners of the window frame 62. A first distal end of each of the top support bars 46 may be welded to top corners of the support frame 44. A second distal end of each of the top support bars 46 may be welded to top corners of the window frame 62.

The top support bars 46 and bottom support bars 46a may form a separation between the fan assembly 20 and the support frame 44 to allow the fresh air 81 to be blown to an interior of an attic assembly 60. The fan assembly 20 may blow fresh air 81 to the interior of the attic assembly 60. The fan assembly 20 may blow hot air 82 out of the attic assembly 60. The hot air 82 may be expelled out of the attic assembly 60 through ridges vent 64. The support frame 44 may have an inclination to face a sun path.

The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
