Abstract:
A dwelling venting and cooling system that includes a set of side-by-side conduits wherein first and third conduits utilize a fan assembly that is actuated by wind power in order to vent hot air from an attic. The second conduit provides an electric fan that actuates the fan assemblies of the first and third conduits at times when wind is not sufficient to actuate the fan assemblies. The system further has attic air ducts that are in communication with vents in rooms within the dwelling in order to convey all hot air to the attic and out of the dwelling. In addition a cooling system that utilizes a water-to-air exchanger provides cool air into air ducts within the dwelling in order to replace the hot air with cool air.

Description:
BACKGROUND OF THE INVENTION 
     This invention relates to a house venting system. More specifically, this invention relates to a venting system that vents air from the attic and the dwelling. 
     For many years attic venting systems have been used in order to vent hot air out of an attic and into the atmosphere. Specifically, known in the art is that heat rises and thus in a home during hot months attics tend to hold a lot of heat. As a result of the attic holding heat the attic naturally warms the rest of the house causing air conditioners to work harder and more inefficiently in order to keep a dwelling cooled. 
     As a result of heat being captured in an attic, vent pipes are traditionally placed through the roof of a house in order to vent out the hot air. In this manner heat continues to rise and vents out of the house cooling the attic area. To improve upon the vent pipe those skilled in the art have added an attic fan that is used to convey air through the vent pipe. 
     While an attic fan does convey some heated air through a vent pipe in order to help solve the problem of the heated attic, many problems still remain. Specifically, problems with air movement still exist because an attic fan on its own is unable to convey hot air out of an attic fast enough to keep the attic sufficiently cool. Additionally, attic fans are typically noisy and can serve as an annoyance to home owners. In addition, at the present time in order to vent air from rooms of a house other than the attic requires unsightly duct work throughout the house. 
     Therefore, a principal object of the present invention is to provide a home venting system that improves upon the state of the art. 
     BRIEF SUMMARY OF THE INVENTION 
     A dwelling venting and cooling system that has a first conduit disposed through a roof of a dwelling and has an exhaust port for conveying air and a fan assembly that is actuated by air exterior to the dwelling to vent air out of the exhaust port. In side-by-side relation to the first conduit is a second conduit that has a closed end and an electric fan that through a plurality of openings can convey air to actuate the fan assembly of the first conduit to vent air out of the exhaust port. An attic air intake duct is then in communication with the first conduit and at least one room in the dwelling to communicate air from the room to the exhaust port.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The figures show a home venting and cooling system  10  used on a house or dwelling  12 . The house or dwelling  12  has a plurality of rooms  14 , an attic  16  and a roof  18 . The home venting system  10  includes first, second and third side-by-side conduits  20 ,  22  and  24  that extend from within a home  12  through the roof  18  and to the exterior of the home  12 . The three conduits  20 ,  22  and  24  are in parallel relation wherein the first and third conduits  20 ,  24  have open ends  26  to convey air from within the home or dwelling  12  to the exterior of the home or dwelling  12 . The second conduit  22  meanwhile has a closed end or cap  28  exterior of the dwelling  12  and instead has openings  30  therein to convey and communicate air flow to the first and third conduits  20  and  24 . 
     The first and third conduits  20  and  24  each have a plurality of louvers or exhaust ports  32  through which air is conveyed. In addition, the first and third conduits  20  and  24  have a shaft  34  disposed therein extending from a first to a second end  36  and  38  with a propeller  40  having blades  41  at each of the first and second ends  36  and  38  to form a fan assembly  42 . Specifically, wind is conveyed onto the propellers  40  at the second end  38  to rotate each shaft  34 . This rotates each fan assembly  42  at the first end  36  of each shaft  34  to draw air toward the first and third conduits  20  and  24  and out of the exhaust ports  32 . 
     The second conduit  22  has an electric fan  44  with a propeller  46  disposed therein so that air can be conveyed through exhaust doors  47  within the second conduit  22  and through the openings  30  within the second conduit  22  onto the propellers  40  of the fans  42  at the first end  36  of the first and third conduits  20  and  24 . Thus, the fan assemblies  42  within the first and third conduits  20  and  24  can either rotate in order to pull air to and through the conduits  20  and  24  out of the home via wind that blows the propeller  40  at the second end  38  of shaft  34  or alternatively by the movement of the air created by the electric fan  44  on the propeller  40  at the first end  36  of the shaft  34 . Specifically, the electric fan  44  is utilized to supplement the force created by the wind. Additionally the second conduit has back draft doors  48  at its second end  38  that prevent back draft and are pulled open when the electric fan  44  operates. 
     Air ducts  50  that extend across a ceiling  52  of the attic  16  are in communication with the first and third conduits  20  and  24  to convey warm air to the conduits  20  and  24 . In communication with the ducts  50  within the attic  16  is a room vent pipe  54  that provides a communication path between the ducts  50  and an opening  56  within a ceiling  57  in a room  14 . In a preferred embodiment the opening  56  is covered by a vent  58  wherein a conventional ceiling fan  60  having a light bulb and shade is attached around the vent  58 . 
     The vent  58  is operably connected to a valve  62  within an intersection between an attic air duct  50  and room vent pipe  54  so that when the vent  58  and valve  62  are closed, the airflow path from the attic is open to convey air from the duct  50  to the first and third conduits  20  and  24 . When the vent  58  and valve  62  are open the valve  62  closes the attic air intake duct  50  and instead provides a flow path from within the room  14  to the first and third conduits  20  and  24 . Thus, warm air at the ceiling  57  of room  14  is conveyed though the room vent pipe  54  and to the first and third conduits  20  and  24  to be expelled at the exterior of the house  12 . 
       FIG. 4  shows an attic air duct  50 . As one can see, the attic air duct  50  has a top portion  66  and a bottom portion  64  wherein the top portion  66  has a plurality of air inlets  68  to take in the hottest air from the attic  16 . The ducts  50  additionally have a plurality of air intakes slots that can have doors  70  that are mechanically connected to the exhaust doors  47  of the second conduit  22  via linkage  71  so that when the electric fan  44  operates the exhaust doors  47  and duct doors  70  simultaneously open in order to intake additional air from the attic  16 . In addition, the duct has a groove  72  at its bottom portion  64  such that dirt within the duct  50  falls out of the bottom of the duct  50  minimizing the dirt and damage to the system  10 . 
       FIG. 5  shows a cooling system  74  utilized to provide cool air to the dwelling  12  in order to replace the hot air being vented by the venting and cooling system  10 . The cooling system  74  utilizes water supplied by a city or well through an intake line  76  and inputs the input line  76  into a water-to-air exchanger  78  and then via a pump  80  returns the water through the water outline  82  of the home for recirculation. The water-to-air exchanger  78  converts the cold water into cooling air that then is conveyed to an air duct  84  that takes that air to different rooms  14  within the dwelling  12 . Thus, the hot air that raises and is vented through the first and third conduits  20  and  24  is replaced with the cool air supplied by the cooling system  74 . The cooling system can additionally include air filters  86  to filter such air. 
     In operation, as wind blows at the exterior of the house  12 , wind flows to rotate the fan propellers  40  at the second end  38  of the shaft to rotate the propeller at the first end  36  of the shaft  34 . This rotation causes air to be pulled from within the attic ducts  50  and conveyed out of the exhaust ports  32  to the exterior of the house  12 . When the wind of the exterior of the house  12  is insufficient to move the fan propeller  40  at a desired rate the electric fan  44  is operated to provide an air flow that flows through the openings  30  within the second conduit  22  directly onto the propellers  40  of the first ends  36  of shafts  34  within the first and third conduits  20  and  24  to rotate the shafts  34  accordingly. By operating the fan  44  the back draft doors  48  are sucked open and the exhaust doors  47  similarly open causing duct doors  70  also to open to improve efficiency. 
     When air in a room  14  is desired to be vented, an individual merely needs to open a vent  58  in the room  14 . By opening the vent  58  a valve  62  closes the attic air intake ducts  50  from the first and third conduits  20  and  24  and provides a communication flow path from the ceiling  57  of the room  14  to the first and third conduits  20  and  24 . Once the room is at a sufficient temperature the vent  58  is closed causing the valve  62  to reopen the flow path from the attic air ducts  50  to the first and third conduits  20  and  24 . 
     When the hot air is thus conveyed from a room  14  to the first and third conduits  20  and  24  the air may then be replaced with air from the cooling system  74 . The cooling system  74  receives water from a water inlet  76  and a water-to-air exchanger  78  converts the temperature of the water to the air temperature within a duct  84  to supply cool air into room  14 . 
     Thus, provided is a home venting system  10  that utilizes wind energy and a small electric fan  44  to convey air from an attic  16 . This reduces the amount of noise generated by a traditional fan used to convey air from an attic  16  and provides improved air movement. In addition, by utilizing the room vent pipe  54  in a vent  58 , an air path is provided to vent air from a room  14  to the exterior of the house  12  without having to present undesirable aesthetically displeasing duct work within a room. 
     It will be appreciated by those skilled in the art that other various modifications could be made to the device without departing from the spirit and scope of this invention. All such modifications and changes fall within the scope of the claims and are intended to be covered thereby.
