The present invention relates generally to ventilation devices and methods and more particularly to a ventilation device suitable for mounting with a vehicle window for ventilation and exhaust of interior air and/or associated airborne impurities or contaminants.
There are two common methods that people use to ventilate a vehicle's interior. One method is to open the vehicle's windows when the vehicle is moving or parked. This method allows smoke, pet smells, and other foul odors to be ventilated to the outside atmosphere, while simultaneously allowing the fresh, outside air to enter the vehicle's cabin. There are, however, some disadvantages to opening the vehicle's windows for ventilation. First, the outside air may not be fresh and clean at all times. For example, the outside air may include rain, snow, pollen, bugs or any number of other outside contaminants, which will also enter the vehicle's cabin. Second, while the vehicle is in a parked position and left unattended, having the windows down may result in the vehicle's theft or vandalism. Third, if the windows are down while the vehicle is in motion, the vehicle's aerodynamic qualities will be affected significantly. Approximately 10% of the vehicle's fuel economy will be lost due to drag forces. Finally, if the windows are down while the vehicle is in motion, a significant noise is produced which will cause discomfort to the ordinary passenger. The passengers will be required to converse at a higher decibel and also be required to turn vehicle audio equipment to a louder setting.
Another method commonly used to ventilate the vehicle is to use the ventilation feature on the vehicle's control panel. This feature allows fresh air at a particular temperature to enter the vehicle's cabin. While the fan functions adequately in most situations, there are some scenarios where the fan still leaves behind undesirable odors. For example, some odors which have penetrated the seat's fabric are not capable of being removed by the fans. Instead, the high velocity air entering the vehicle's window, while the vehicle is moving at high speeds, is more suitable for removing these types of odors.
Various solutions have been proposed to resolve the problem of safe vehicle ventilation. One such solution proposes using a panel mountable between a window frame and a window. Although prior art devices allow air to exchange between the vehicle's exterior and its interior, only one of these prior art devices forcefully removes air from the vehicle's interior by creating a pressure differential between the vehicle's interior and its exterior. Forceful air removal increases the speed with which the vehicle's interior is ventilated and the obnoxious odors are removed. Several drawbacks exist in the current art which include, but are not limited to, requiring the mounting of a device between the window and the window frame, the window not being capable of fully closing, inefficient pressure differential along the device, and water leakage possibilities around the device.
What has been lacking, however, until the present invention, and what the industry long has sought, is a cabin exhaust device that has flexibility in its mounting, allows the windows to fully close when exhaust is not needed, creates a more efficient pressure differential throughout the device's length and prevents water leakage around the device.
It is, therefore, an object of the present invention to disclose and claim a cabin exhaust device for use in vehicles with retractable windows.
It is another object of the present invention to provide a cabin exhaust device that facilitates the creation of a vacuum, or pressure differential, between the vehicle's interior and its exterior and along the entire length of the cabin exhaust device.
It is another object of the present invention to provide a cabin exhaust device that allows the windows to fully close while the cabin exhaust device is mounted.
It is another object of the present invention to provide a cabin exhaust device that vents cabin heat and removes odors when the vehicle is either parked or in motion.
It is yet another object of the present invention to provide a cabin exhaust device which keeps out dust, pollen, allergens, and other similar pollutants.
It is a further object of the instant invention to provide a cabin exhaust device which is easy to position and mount.
It is yet another object of the present invention to provide a cabin exhaust device which can be mounted on the outside of the door frame or in an opening between the window panel and the window frame.
It is still a further object of the present invention to provide a cabin exhaust device which is inexpensive to manufacture.
It is yet another object of the present invention to provide a cabin exhaust device which helps lower the temperature inside the cabin when the vehicle is stationary, thereby preventing the deterioration of adhesives within the vehicle, extend the life of plastics and other materials within the vehicle, and provide environmental safety to the vehicle's passengers by eliminating plastic and glue fumes as well as other contaminants that accumulate in the vehicle's cabin.
It is yet another object of the present invention to provide a cabin exhaust device which provides cabin ventilation in a fuel efficient manner.
It is yet another object of the present invention to provide a cabin exhaust device that prevents rain from entering the vehicle's cabin.
It will become apparent to one skilled in the art that the claimed subject matter as a whole, including the structure of the apparatus, and the cooperation of the elements of the apparatus, combine to result in the unexpected advantages and utilities of the present invention. The advantages and objects of the present invention and features of such a cabin exhaust device will become apparent to those skilled in the art when read in conjunction with the accompanying description, drawing figures, and appended claims.
The present invention, when properly installed, creates a vacuum effect within the vehicle's interior resulting in odors, dust, and other airborne particulates being drawn from the vehicle's interior to its exterior. The present invention can be used for a variety of applications including, but not limited to, applications where air is desired to be vented from the interior of an apparatus to its exterior upon the apparatus' movement, thereby creating a vacuum within the apparatus' interior.
The cabin exhaust device can be mounted either on the exterior of the door frame or in an opening between the window panel and the window frame. The window is able to fully close, thus, allowing the user to easily control the on/off of the pressure differential. Also, an air dam is strategically located so that a pressure differential is created along the entire length of the cabin exhaust device. Finally, a drip shield, either integrated or non-integrated, is placed at the cabin exhaust device's lower edge to prevent rain from dripping into the vehicle's cabin. There are many more advantages provided by the present invention. Although at least one embodiment has the cabin exhaust device mounted either on the exterior of the door frame or in an opening between the window panel and the window frame, those skilled in the art will appreciate that the cabin exhaust device may also be mounted anywhere in the body of the vehicle without departing from the scope and spirit of the present invention.

It will be understood by one skilled in the art, however, that these aperture angles may vary, so long as a pressure differential is created between the vehicle's interior and its exterior which thereby creates a vacuum within the vehicle's interior, without departing from the scope and spirit of the present invention. The apertures 35 can be formed in a staggered relationship with respect to each other, in alignment, or positioned in any random order, as desired. Each aperture 35 is approximately 3/32″ in diameter and spaced between 1/18″ to ¼″ intervals. Although this embodiment depicts and discloses various diameters, intervals and aperture shapes, the diameters, intervals and shape of the apertures may vary in size and shape (e.g., any geometric shape) without departing from the scope and spirit of the present invention.
As seen in
The cabin exhaust device's 10 method of use can be understood by explanation while viewing
When the vehicle is in motion, the pressure is reduced along the ventilating panel's 20 outer surface 32 due to the airflow along the angle and positioning of the first portion's 24 and second portion's 26 apertures 35. A vacuum effect is thereby created to forcefully push the air from within the vehicle's interior to its exterior. The maximum vacuum effect occurs when all the apertures 35 are exposed to the vehicle's interior. This effect occurs when the window panel 16 is lowered to a point where the window panel's 16 top edge 17 barely remains in a continuous sealed contact with the squeegee 50.
Once the window panel 16 is rolled down to a point where the window panel 16 is no longer in a continuous sealed contact with the squeegee 50, the vacuum effect is significantly reduced. At this point, the squeegee 50 no longer forms a barrier between the vehicle's interior air and the outside atmosphere, thus resulting in zero pressure differential.
There are several benefits which arise from the present invention. First, an air dam 38 is strategically placed along the ventilating panel 20. As the vehicle moves in a forward motion, turbulence is first created by the relative wind created by the motion which then contacts the edge of the vehicle's windshield (not shown) and the front edge of the first portion 24, which causes a pressure decrease or differential along the ventilating panel's 20 first portion 24. Thus, a vacuum effect is created in the vehicle's interior along at least the first portion 24. Turbulence is next created at the strategically located air dam 38, which causes an additional pressure decrease or differential along the ventilating panel's 20 second portion 26. Thus, a vacuum effect is created in the vehicle's interior along at least the second portion 26. Hence, there is now a complete vacuum effect created along the entire first portion 24 and second portion 26.
Second, a drip shield 40 is attached longitudinally along the entire ventilating panel's 20 bottom side 30 and allows for a partial window panel 16 opening that exposes the interior to be shielded from rain and direct wind. The drip shield 40 also proves to be beneficial to the increasing use of internet cable hookup located at numerous truck lots.
Third, the apertures 35 are designed to also serve as a rain-retarding barrier via their positionally disposed angles and precise mold shutoffs.
Fourth, the rear panel 60 serves as an additional rain-retarding barrier to prevent rain and other environmental nuisances from entering the vehicle's cabin. Although the apertures 35 are designed to prevent rain from entering the vehicle's cabin, the rear panel 60 further serves as a secondary protective layer.
Finally, since a vacuum effect is created within the vehicle's interior, the airflow controlled via the vehicle's control panel (not shown) increases even when the setting remain the same. This results in a more efficient airflow with lesser fuel consumption.
As seen in
The cabin exhaust device 10 can be manufactured in pairs, one for a driver's side and one for the passenger's side of a vehicle, it being understood that the passenger's side cabin exhaust device 10 is a mirror image of the driver's side cabin exhaust device 10. As previously described, since the cabin exhaust device 10 is formed from a transparent material, the driver's vision is not impaired.
The present invention underwent numerous and rigorous testing procedures as will now be described:
Stationary Exhaust Testing: Acknowledging that hot air rises and a plurality of holes provide a natural means of exhaust within a stationary vehicle, the inventor vertically angled the apertures, having the aperture inlets on the ventilating panel's inner surface and positioned vertically higher than the aperture outlets located on the ventilating panel's outer surface, thus creating a rain-retarding barrier.
Rain-Retardant Testing: The present invention was installed in a truck window and subjected to a variety of rainy conditions. The results revealed a dry inner surface with no rain entering the vehicle's interior. These results were very successful, which lead to even further testing. The further testing was conducted by simulating rain, via a common showerhead, under several different flow selections and angles. These further tests were as successful as the initial tests. Thus, it was decided that a cabin exhaust device having apertures positioned at a vertical angle, wherein the aperture inlets are located on the inner surface and positioned vertically higher than the aperture outlets located on the outer surface, creates a rain-retarding barrier. When the aperture angle is manipulated, the possibility of creating vacuum in the vehicle's interior exists when the vehicle is in forward motion.
Vacuum Testing: While a vehicle is in forward motion, a pressure differential sustaining vacuum within the vehicle's interior is created along the cabin exhaust device when the apertures are positioned at an upward and forward angle from the outer surface to the inner surface. Testing showed that angling the apertures closer to the horizontal increased the vacuum strength, but decreased the rain-retardant capabilities. The addition of a smooth bell-shaped trough to the aperture's outlet terminal point proves to assist with water displacement. The ideal angle was achieved by testing different aperture angles in a rain environment. Ideal diametric sizing was achieved by testing different sizes at the ideal angle position and comparing the noise versus vacuum results. Once ideal angle and ideal diametric sizing was achieved, further testing was performed for vacuum and noise in the diesel truck cabin, while the truck moved forward at various speeds. The testing results showed that outwardly convexing the ventilating panel would increase vacuum potential. During testing, the number of apertures were increased and decreased until the desired vacuum was achieved. Further testing revealed the ability to engage and disengage the cabin exhaust device's vacuum ability by using the cabin's console “recirculation” and “fresh air” options. The console's “fresh air” mode increases circulation, while the “recirculation mode” decreases vacuum to a minimum.
Conclusion: Final testing revealed a cabin exhaust device that provided a continuous interior exhaust at a level sufficient enough to eliminate unwanted odors and excessive heat, with minimal temperature change from selected climates. The cabin exhaust device reduced interior fogging as well as sheltered the vehicle's interior from rain, dust and pollen accumulation, unauthorized intrusions, direct heat and ultraviolet rays.
