Description
- This application claims priority to provisional application No. 60/983,951 filed Oct. 31, 2007 entitled Toilet Ventilation System and incorporates by reference the provisional application in its entirety.
- The present invention relates to a ventilation system for toilets. More particularly, the present invention relates to toilet systems having a ventilation system designed for venting odoriferous air from a toilet.
- Many ventilation systems have been employed to minimize and dissipate foul bathroom odors within lavatory facilities. Fans such as ceilings are commonly used. However, ceiling fans only ventilate unpleasant odors after they have already diffused throughout the lavatory facility. Consequently, even with operable ceiling fans, objectionable odors are still present in lavatories. Furthermore, ceiling fans are relatively inefficient because they continuously ventilate large volumes of air from the entire lavatory.
- Ventilation systems that are built into the toilet itself have been invented. Some of these systems can perform their function in a workmanlike manner. However, ventilation systems that are built into the toilet can be difficult to assemble and expensive to install. Some such systems are not made to be removable, and generally cannot be easily retrofitted to existing toilets.
- The present invention provides a simple, removable ventilation system designed for use in new or existing toilets. The ventilation system of the present invention is inexpensive and can be installed by a person of minimal mechanical aptitude.
- The present invention relates generally to a ventilation system for use with a typical household or commercial toilet. The typical toilet includes a tank for holding water, and passageways for transporting the water from the tank to the bowl in the base portion of the toilet. The base portion of the toilet defines a plurality of ports for directing water into an interior of the toilet bowl, and an interior passageway for conveying water from the tank to the ports of the toilet bowl.
- Water flowing from the tank into the bowl causes a surge in the bowl. The surge causes water in the bowl to push into a U-shaped pipe, upwards around the apex of the “U” in the pipe, pushing the air pocket down into the sewer. This creates a siphon which draws a continuous flow of water from the bowl and through the pipe. When the tank empties so that there is no more water in the bowl, air fills the “U” in the pipe, stopping the siphon. Once the siphon is interrupted, water fills the tank and re-fills the bowl. The water stops flowing into the bowl when a float in the tank raises with the water level in the tank to a high enough level which allows a tank valve to close.
- The present invention comprises a vent collar mountable between the tank portion and the base portion of the typical toilet. A vent collar is placed between the tank and bowl portions of a toilet and secured by conventional means, such as by replacing the original equipment bolts that attach the toilet tank to the toilet base with elongated bolts. The ventilation collar includes a ventilation port that can be connected to a ventilation line or pipe. The line or pipe can then be connected to a ventilation fan to pull odoriferous air from toilet. The ventilation line and pipe can be placed in any suitable location to directs odoriferous air outside of the restroom or lavatory facility, such as into an attic or to the exterior of the building in which the restroom or lavatory is situated
- The vent collar includes a passageway that is in the water flow path between the tank and base portion of a conventional toilet. When water is not in the water flow path, the ventilation fan can draw air from the toilet bowl through the ports of the bowl and through the vent collar. Air drawn through the vent collar exits the toilet structure through a ventilation port. If water is in the passageway, the vent collar baffle and an annular air space defined by the vent collar baffle and the vent collar housing prevents water from being extracted by the ventilation fan into the ventilation line. During testing, it was found that the ventilation system of the present invention was successful in removing essentially all of the foul odor present in the normal use of bathroom facilities. The ventilation system provides inexpensive, easy to install ventilation in a manner unforeseen in the prior art.
- A variety of advantages of the invention will be set forth in part in the description that follows, and in part will be apparent from the description, or may be learned by practicing the invention. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention as claimed.

The tank includes abottom wall 71 which includes aflush valve aperture 72. Flush valve controls 32 water flow throughflush valve aperture 72. - A
conventional float arrangement 21 is used to control the water level intank 16. For example, when thetoilet 10 is flushed, the water level in thetank 16 drops causing thefloat arrangement 21 to also drop. When thefloat arrangement 21 drops, a valve (not shown) is caused to open flow between theinlet line 19 and thetank 16. As the water level in thetank 16 rises, thefloat 21 also rises. When thefloat 21 reaches a predetermined level (shown inFIG. 1 ), the valve (not shown) closes and flow is stopped between theinlet line 19 and thetank 14. - Referring to
FIG. 1 , theflush valve aperture 72 is used to discharge water through the bottom of thetank 16 when thetoilet 10 is flushed. Theflush valve aperture 72 is opened and closed by aconventional flush valve 32 such as a flapper or plunger valve. A conventional flush control such as ahandle 33 andchain arrangement 35 is used to open and close theflush valve 32. To flush thetoilet 10, thehandle 33 is pressed downward causinglever 34 andchain 35 to lift theflush valve 32 to an open position. - With the
flush valve 32 in the open position, the water in thetank 16 is discharged through theflush valve aperture 72. After the water has been discharged through theflush valve aperture 72, theflush valve 32 moves to a closed position (shown inFIG. 1 ) such that the tank can be refilled with water. - The
bowl 14 of thetoilet 10 includes a siphonsystem 64. The siphonsystem 64 controls and maintains the level of water in the bowl. The siphonsystem 64 of the toilet begins with the drain portion of thetoilet 66 of thetoilet 16. Gravity will force water through thedrain portion 66, through au-shaped drain pipe 68. There is apeak portion 70, where the force of gravity is not great enough to force water to leave the system absent the flush. When a flush occurs, a large volume of water enters thebowl 14, forcing the contents of the tank over thepeak portion 70 and into a sewer or septic system (not shown). -
Toilet base portion 12 includes acircumferential rim portion 74 encirclingbowl 14.Rim portion 74 includes arim chamber 76. Thetoilet rim portion 74 defines a plurality ofports 78 in fluid communication with therim chamber 76. Thetoilet base portion 12 includes abase aperture 73 that is in communication withintermediate chamber 79.Intermediate chamber 79 and therim chamber 76 cooperate to form an interior passageway that provides fluid communication betweenbase aperture 73 andports 78. When the toilet is flushed, water flows fromtank 10, throughflush valve aperture 73 throughvent collar 36, intointermediate chamber 79 andrim chamber 76 before exiting throughport 78 intobowl 14. - The
ventilation system 20 of the present invention comprises avent collar 36 connected to afan 60 and is designed to be installed into astandard household toilet 10, shown inFIG. 1 . Thetoilet 10 includes all of the features of any commercial toilet, including abase portion 12, which includes thebowl 14, and atank portion 16. - The
vent collar 36 comprises ahousing 80 and abaffle 46. As shown inFIG. 3 , thehousing 80 is generally cylindrical and made of a water resistant material, such as PVC. Thehousing 80 includes atop end 38, abottom end 40, andwall 81 withouter surface 42 and aninner surface 44 definingpassageway 45. -
FIGS. 3-5 illustrate thevent collar housing 80. Thehousing 80 is generally cylindrical in shape with awall 81 having a reduced diameterfirst aperture 82, an enlargedintermediate diameter passageway 84, and a reducedsecond aperture 86. Thehousing wall 81 has aninner surface 44 and anouter surface 42. Thehousing 80 also includes aventilation port 88. As shown in the embodiment depicted, theventilation port 88 hasfemale threads 54 for receivingmale threads 56 ofadapter 58 which can be connected toventilation line 23. - The reduced
first diameter 82 of the housing can include alip 50 for receiving aflange 51 on thebaffle 46. Thebaffle 46 is generally cylindrical with awall 90 having aninner surface 94 and anouter surface 92. The baffle wall includes a plurality of generally radically extendingports 49 that allow air to push through the baffle wall. Baffle fittedportion 53 is accepted into housingsecond aperture 86. - Referring to
FIG. 4 , disposed withinhousing 80 isbaffle 46.Baffle 46 is a generally cylindrical with a plurality ofopenings 49 which allowfan 60 to draw fouled air throughpassageway 45, while at the same time minimizing the extrusion of water fromventilation port 88 during the flush cycle. Thebaffle 46 is one of the most important features of the present invention. Because thetoilet vent collar 36 is designed to allow installation in an ordinary toilet without any major structural changes to the toilet, the system is at risk of water entering the fan.Baffle 46 discourages water from exiting throughventilation port 88. -
Vent collar 36 is designed to be retrofitted into the tank of any existing toilet. Another embodiment would include a version of thevent collar 36 pre-manufactured into a toilet. -
Baffle 46 is disposed within thevent collar housing 80; thereby forming anannular air chamber 96 defined by the baffleouter surface 92 and the housinginner surface 44, which is best seen inFIG. 5 . Thebaffle ports 49 are angled in the embodiment shown. The angling of thebaffle ports 49 aids in resisting the flow of water out of theventilation port 88. An important feature of thevent collar 36 is theannular air chamber 96 defined by the baffleouter surface 52 and the housinginner surface 44. Water that escapes from thebaffle 46 will be trapped by the housing wallinner surface 44 and flow back into the inner diameter ofbaffle 46 throughbaffle ports 48. - Returning to
FIG. 1 ,first seal ring 52 assists in making water-tight the union between thetank 16 and thevent collar 36.Second seal ring 48 assists in making it water tight the union between thebaffle 46 andtoilet base 12. - As those skilled in the art appreciate the
