Description
- This invention generally relates to bathroom apparatus and more specifically to a toilet odor removal system.
- Toilets are an indispensable bathroom fixture and their basic flushing system has changed little over time. Modern toilets do little to reduce the emission of offensive odors during their use. In addition to creating a disagreeable experience, offensive odors are micro-particles that could contain viruses or other health contaminates. Reducing offensive odors while using a toilet has the medical health benefits
- Conventional odor removal systems typically use a fan mounted on a wall of the room to discharge the offensive odors through a vent. These systems are not very effective and also have the disadvantage of removing the offensive odors only after they are released into the bathroom. These systems are also generally loud and do little to keep the offensive odors from escaping the bathroom.
- Other odor removal systems attempt to remove the offensive odors from the bowl of the toilet. One such system utilizes a fan to suck air from the bowl of the toilet and discharge it through a filter system located in the same room as the toilet. Another system discharges the gas through the water trap of the toilet. These odor removal systems have also not proven to be very effective.
- Another problem is that modern toilets remain prone to clogging and with restrictions in water use, clogging is becoming an ever greater problem. Various solutions have been developed to minimize clogging, including pressurizing the water and streamlining the discharge system. These systems help reduce clogging, but are not effective in all situations.
- A toilet odor removal system and its various implementations is provided. In one embodiment of the present invention, the toilet odor removal system comprises a bowl, a sealed seat and a gas removal system in fluid communication with the bowl. The sealed seat operates to form a substantial seal between a rim of the bowl and a user. The gas removal system operates to substantially remove and discharge any gases in the bowl.
- In a particular embodiment of the toilet odor removal system, the toilet includes an integrated conduit that is fluidly connected to ports in the bowl. In this embodiment, water is also flushed through the ports during when the toilet is flushed. An advantage of this embodiment is that the ports are cleaned each time the toilet is flushed.
- In another embodiment, the gas removal system includes an intake ring that operates to remove the gases from the bowl. In this embodiment, the intake ring is preferably positioned in the bowl below the rim so that water cleans the intake ring.
- In another embodiment, the sealed seat includes orifices that are in fluid communication with the bowl and the gas removal system. In this embodiment, the gases in the bowl are removed through the sealed seat and then discharged through the gas removal system. In the preferred implementation of this embodiment, the sealed seat includes a replaceable gasket having an annulus and orifices that are in fluid communication with the gas removal system and the bowl. An advantage of this embodiment is that the gasket can be replaced when it gets dirty.
- In another embodiment of the present invention, an odor removal kit for a toilet is provided. In this embodiment, the odor removal kit includes a sealed seat having a seat and a gasket, and a gas removal system. The seat can be attached to a bowl of the toilet and the gasket operates to form a substantial seal between a rim of the bowl and the seat. The gas removal system can be connected to the sealed seat and operates to remove gases from the bowl of the toilet. In a particular implementation of this embodiment, the gasket includes an annulus and orifices through which the gases are removed from the bowl of the toilet.
- In yet another embodiment of the present invention, a sealed seat for a toilet odor removal system is provided. In this embodiment, the sealed seat comprises a seat and a gasket. The sealed seat is operable to be attached to a bowl of a toilet and a gas removal system. The sealed seat includes an annulus, at least one orifice operable to fluidly connect the annulus to the bowl and a connector that fluidly connects the annulus to the gas removal system. The gasket operates to form a substantial seal between the seat and the rim of the bowl of the toilet. In a particular implementation of this embodiment, the annulus and orifices are disposed within the gasket. In this embodiment, the gasket may include an adhesive as a gasket retaining system so that the gasket can be removed and replaced.
- In yet another embodiment of the present invention, a replacement gasket for a toilet odor removal system is provided. In this embodiment, the gasket operates to form a substantial seal between a seat and a rim of a bowl of the toilet. In a particular implementation, the gasket includes an adhesive operable to attach the gasket to the seat. In another implementation, the gasket also includes a seal and a connector. The seal includes an annulus and orifices through which gases can be removed from the bowl. The connector connects the annulus to the gas removal system.
- The present invention has several important technical advantages. Various embodiments of the present invention may have none, some, or all of these advantages. An advantage of at least one embodiment of the present invention is that health risks are reduced by minimizing the release of particle contaminates from the toilet. Another advantage is that offensive odors are substantially reduced before they escape the bowl of the toilet.
- An advantage of at least one implementation is that a conventional toilet can be retrofit to obtain the advantages of the present invention. An advantage of another implementation is that the toilet odor removal system is automatically cleaned when the toilet is flushed. Yet another advantage of at least one implementation is that the gasket is replaceable.

FIGS. 1 through 4B illustrate various embodiments of the present invention. The present invention is illustrated in terms of a bowl-type toilet. It should be understood that the present invention may be used in any type of toilet or such other similar fixture without departing from the spirit and scope of this invention. For example, the present invention may be used in pan-type designs instead of a bowl-type toilet design as illustrated herein. -
FIG. 1 is a cross-sectional view of a toiletodor removal system 10. In the embodiment illustrated, the toiletodor removal system 10 includes atoilet 11 having abowl 12 with arim 14, adischarge system 16, awater supply system 18, a sealedseat 20 and agas removal system 22. When a user sits on the sealedseat 20, the sealedseat 20 engages therim 14 and a relativelyclosed cavity 24 is formed between the user, sealedseat 20 andbowl 12. Thegas removal system 22 is fluidly connected to thebowl 12 and operates to substantially remove the air and anyoffensive odors 26 from thecavity 24 and discharge them to the outside 28. As a result, anyoffensive odors 26 are substantially removed from thecavity 24 before they can escape into the room. - The
water supply system 18 operates to deliver water to thebowl 12. Thewater supply system 18 is generally incorporated into thetoilet 11 and includes aflushing system 29 that operates to deliver water from areservoir 30 to thebowl 12. In the embodiment illustrated, thereservoir 30 comprises a holding tank. In other embodiments, thereservoir 30 may comprise a direct water feed or include a water pressure pump to increase the water pressure delivered to thebowl 12. Theflushing system 29 may also include other mechanism and valves for delivering water to thebowl 12. - The
reservoir 30 typically delivers water to thebowl 12 through a series ofducts 31 that discharge water into thebowl 12 atports 32 generally located belowrim 14. When activated by theflushing system 29, i.e., flushed, the water from thereservoir 30 is released through theports 32 into thebowl 12. Theports 32 are often optimized to cause a swirling motion to facilitate the cleaning of thebowl 12 and discharge of any waste materials through thedischarge system 16. - The
discharge system 16 is connected to thebowl 12 and operates to remove the water and any waste materials from thebowl 12. Thedischarge system 16 typically includes piping 34 and atrap 36, such as a S-type trap or a P-type trap. Thedischarge system 16 is connected to a sewer system, septic system or other type of waste removal system. In the preferred embodiment, thedischarge system 16 also generally includes adischarge vent 38 that operates to vent sewer gases to the outside 28. - The sealed
seat 20 provides a comfortable seating surface for the user and also forms a substantial seal between the user and therim 14 of thebowl 12. Thecavity 24 formed by the user, sealedseat 20 and thebowl 12 is not required to be fully enclosed or sealed, but the better the seal—the better the removal of theoffensive odors 26 from thecavity 24. The sealedseat 20 may comprise any acceptable design and components, some of which are described in greater detail below. - A
volume 40 is associated with thecavity 24. Thegas removal system 22 operates to remove theoffensive odors 26 from thecavity 24 at adischarge rate 41 to form amild vacuum 42 within thecavity 24. Thevolume 40,discharge rate 41 andvacuum 42 are interrelated and impact the effectiveness of theimproved toilet 10 at minimizing the escape of theoffensive odors 26 from thecavity 24. For example, thedischarge rate 41 is affected by thevacuum 42 and size of the ducts removing theoffensive odors 26 from thecavity 24. Thevacuum 42 is affected by thedischarge rate 41 and thevolume 40. - In general, the larger the
volume 40 of thecavity 24, the greater thedischarge rate 41 and/orvacuum 42 required to effectively remove theoffensive odors 26 from thecavity 24 by thegas removal system 22. Thevolume 40 is principally determined by the design of thebowl 12. Thedischarge rate 41 and thevacuum 42 are determined by thegas removal system 22. - The
discharge rate 41 of thegas removal system 22 impacts the effectiveness of theimproved toilet 10 at minimizing the escape of any air andoffensive odors 26 from thecavity 24. In general, ahigher discharge rate 41 minimizes the air andoffensive odors 26 that can escape thecavity 24. In most applications, thegas removal system 22 should operate at adischarge rate 41 of 2-20volumes 40 per minute. In the preferred embodiment, thegas removal system 22 operates at adischarge rate 41 of 5-10volumes 40 per minute. - The
vacuum 42 applied to thecavity 24 also impacts the effectiveness of theimproved toilet 10 at minimizing the escape of theoffensive odors 26 from thebowl 12. Alow vacuum 42 is more likely to allow the air andoffensive odors 26 to escape thebowl 12. Ahigh vacuum 42 minimizes the opportunity for the air andoffensive odors 26 to escape thebowl 12, but it can also be problematic for the user. For example, ahigh vacuum 42 can cause the user to be become stuck to the sealedseat 20, create dry chaffing on the user or create an uncomfortable pressure on the user. In most applications, thevacuum 42 delivered to thecavity 24 is 0.5 to 5 PSI, meaning that the air pressure at thecavity 24 is 0.5 to 5 PSI less than the air pressure outside theimproved toilet 10. In the preferred embodiment, thevacuum 42 is within the range of 1.5 to 3.0 PSI. - The
gas removal system 22 includes anevacuation device 44 and aswitch 46. Theevacuation device 44 is in fluid communication with thecavity 24 and operates to remove theoffensive odors 26 from thecavity 24 and discharge them to the outside 28. Theevacuation device 44 can comprise any suitable device or system that is capable of moving gases at asuitable discharge rate 41 and create asuitable vacuum 42, such as a blade fan, squirrel fan, vacuum fan or water fan. In the preferred embodiment, theevacuation device 44 comprises a direct current blade type electric fan that is moisture resistant. - The
evacuation device 44 may be located remotely to minimize the noise heard by the user. In particular, theevacuation device 44 is preferably built into awall 47 of the bathroom and discharges theoffensive odors 26 into thedischarge vent 38. Theevacuation device 44 is also preferably located higher than thereservoir 30. This provides an additional safety factor by preventing potential water leakage into thegas removal system 22 and potentially shorting theevacuation device 44. Thegas removal system 22 may also include a one-way valve 48, such as a flapper valve, that operates to prevent air from thevent 38 from migrating into thebowl 12 when theevacuation device 44 is not operating. - The
switch 46 operates to activate theevacuation device 44. In one embodiment, theswitch 46 includes asensor 50 that automatically detects the presence of the user and activates theevacuation device 44. Examples include a pressure switch that detects the user sitting on the sealedseat 20, an optical switch or an infrared switch. In another embodiment, theswitch 46 is a manual switch that is operated by the user, such as a wall mounted switch. In each case, the preferred embodiment of theswitch 46 includes atimer 52 operable to maintain the activation of theevacuation device 44 during an established time period. Thegas removal system 22 and its components may comprise other suitable devices and systems for removing theoffensive odors 26 from thecavity 24. -

conduit 200 is integrated with a water supply system 18 a so that theoffensive odors 26 are removed throughports 32 a in thebowl 12 a. Avalve 202 preferably connects theconduit 200 toducts 31 a. Thevalve 202 operates to prevent water from being sucked through theconduit 200 into theevacuation device 44 when theflushing system 29 a is activated and water discharges through theducts 31 a andports 32 a. Thevalve 202 may comprise any type or style of suitable device, such as a flap valve, back-flow prevention valve, gate valve or globe valve operated by the flushing system, mechanically or electrically. - The
evacuation device 44 may also be turned off when theflushing system 29 a is activated to further reduce the possibility of water being sucked into theevacuation device 44. Theports 32 a,ducts 31 a, andconduit 200 are sized to provide anadequate discharge rate 41 for removing theoffensive odors 26 from thebowl 12 a. - An advantage of this embodiment is that the
ports 32 a are cleaned each time thetoilet 11 a is flushed, thereby minimizing cleaning and potential contamination of thetoilet 11 and/or thegas removal system 22. Thetoilet 11 a may comprise other suitable devices and embodiments of the denoted components. For example, theconduit 200 may be fluidly connected to thebowl 12 a via one or more dedicated orifices integrated into thebowl 12 a. In addition, theports 32 and orifices may be shaped to prevent water from thebowl 12 a from contaminating theconduit 200 and thegas removal system 22. -
FIG. 3 is a cross-sectional side view of agas removal system 22 a in accordance with one embodiment of the present invention.
