Abstract
An air ventilation system is provided for removing obnoxious odour air directly from a toilet bowl. The system includes a portal vent formed at the rear underside of the toilet seat. A lateral tube is mounted to the hinge brackets for pivotally mounted the toilet seat to the toilet bowl. The lateral tube has an air inlet opening which is aligned with the portal vent when the toilet seat is at the down position to form an air flow channel. The portal vent and the air inlet opening are offset with one another when the toilet seat is at the up position thus closing the air flow channel to prevent water from overflow or splash to enter into the system. The air flow channel is coupled to a fan for drawing the odour air to the outdoor. A rubber gasket is mounted at the underside of the toilet seat to provide a perfect air seal between the seat and the toilet bowl.
Description
SYSTEM FOR DIRECTLY VENTING ODOUR AIR FROM TOILET BOWL
BACKGROUND OF THE INVENTION
This invention relates to a system for venting toilet bowl odour and in particular a venting system which may be incorporated to a toilet seat for removing odow during use of the toilet.
Toilet bowl ventilation systems are well known. Such systems are shown in Canadian patents: No.914,853 to C. Duguay, issued November 21, 1972; No.1,109,604 to R.
Stamper, issued September 29, 1981; No.1,252,255 to J. L. Joseph et al; and Canadian patent applications:
No.2,023,080 filed August 10, 1980 by B. Dupont; No.2,110,144 filed November 26, 1993 by S.
W. Allen; No.2,226,021 filed December 31, 1997 by S. C. Donald et al; and No.2,262,747 filed August 16, 1996 by M. Ehrensperger et al. However, the known devices are bulky, inconvenient to use, and difficult to retro-fit to the toilet bowl. Furthermore, the known devices contain electrical or mechanical components which will be located in close proximity to the water in the toilet bowl and the water tank thereby presenting a potential danger of electrical and mechanical 1 S hazards in the event of water overflow or back splash from the toilet bowl, or by vandalism or abuse of the device. Prior art devices are incorporated with a clip on attachments to the toilet so that they require modification to be made to the toilet bowl or the water tank for installation so that they are inconvenient or difficult for a user to install and to maintain.
Furthermore, they present an electrical danger both in installation and use.
A ventilation fan is commonly provided in the ceiling of a bathroom for discharging air and foul odour from the bathroom to outdoor. Such ventilation method is very inefficient, given its power specifications, since the foul odour must first permeate the entire room before it is discharged slowly to the outside.
Worldwide, water conservation is becoming a growing concern. Some countries have already mandated toilets to use a limited maximum volume of water per flush.
Such toilets use less water while providing greater water pressure in the flush. They can satisfactorily eliminate solid and liquid wastes; however, they do not provide means for removing gaseous wastes during use of the toilet. To eliminate foul odour in the bathroom, it is common knowledge that users would flush the toilet three or more times in the attempt to remove the embarrassing foul odour.
Considering broadly, the task of eliminating offensive and noxious odow is best achieved by venting them to the outdoor. Recirculating the air internally and adding perfume is but a second best solution. Venting the room air through a window, or under the floor to the air vent system of the plumbing system is overly cumbersome and unnecessary. The standard bathroom fan is sufficiently powerful to draw the odour in the bathroom to the outdoor provided that the air duct and the portal opening has proper dimensions to ensure a maximum air flow return without the need of exorbitant drawing power. A large power fan would create sound and 1 S comfort nuisances.
SUMhdARY OF THE INVENTION
It is the principal aspect of the present invention to provide a foul odour ventilation system for a toilet which is self contained within the non-hollow toilet seat.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to the drawings, the air ventilation system of present invention may be incorporated in a non-hollow toilet seat 1 having a toilet seat cover 2. The toilet seat 1 has a portal vent 3 formed in its rear underside. The portal vent 3 extends into the solid materal of the toilet seat 1 and it is located adjacent to the sowce of obnoxious odow created within the toilet bowl 18. The toilet seat 1 may be mounted to the toilet bowl 18 by two hinge mounting brackets or clips 4 with two fastening bolts 5. A lateral tube 7 is fixedly mounted to the mounting brackets 4 so that the toilet seat 1 may be swivel between a down position covering over the toilet bowl 18 or an up position away above the toilet bowl. The lateral tube 7 has an air inlet opening 8 which is aligned with the portal vent 3 of the seat 1 when the latter is at the down position. The lateral tube 7 are open at both ends, and one end of which may be connected to a wall pipe 12 through an elbow 10 while the other end is closed by a cap 11.
The wall pipe 12 extends through a wall of the bathroom behind the toilet with a wall mounted nipple plate 14. A
drainage valve 13 is provided in the wall pipe 12 to facilitate for discharge of condensation or liquid from the wall pipe 12.
A rubber gasket 19 is mounted at the underside of the toilet seat 1 by a recess grove 20 formed in the under swface of the toilet seat 1. The rubber gasket 19 provides a maintenance free operation and creates a perfect air seal between the rim of the toilet bowl 18 and the bottom of the toilet seat 1. The rubber gasket 19 encircles the bottom surface of the toilet seat 1.
When the toilet seat 1 is at the down position as best shown in Figure 4A, the rubber gasket 19 forms a perfect air seal between the seat and the toilet bowl. The splash guard 6 forming part of the toilet seat 1 sits on top of the toilet bowl 18. In this position, the portal vent 3 of the toilet seat is aligned with the air inlet opening 8 of the lateral tube 6 to form a short compact air flow channel for the foul odour air in the toilet bowl to be drawn directly into the lateral tube 7. The lateral tube 7 is coupled to a flexible air duct 15 connected to a ceiling mounted fan 16 which is operable to draw the foul odour air to the outdoor immediately after it is created in the toilet bowl thus preventing the foul air from filling the cavity of the toilet bowl and to permeate into the bathroom.
When the toilet seat is at the up position as best shown in Figure 4B, the lateral tube 7 is turned to the position at which the portal vent 3 and the air inlet opening 8 are no longer aligned S with one another so that the lateral tube 7 forms a sleeve closing the air flow channel. The splash guard 6 prevents any water overflow or back splash from entering into the lateral tube through the air flow channel. The small spacing between the lateral tube 7 and the toilet seat 1 would still allow some air flow through the system so as not to create undue stress on the ventilation fan 16.
As shown in the overall perspective view of the system in Figure 5, the complete air flow channel originates within the air space of the toilet bowl. It then extends through the portal vent 3 into the lateral tube 7 and into the wall pipe 12. Subsequently the air is drawn upwards through the flexible air duct 15 by the fan 16 for expel to the outdoor.
The operation of the system is extremely easy and simple. Upon entering the bathroom, the user turns on the operating switch 17 to operate the ventilation fan 16.
When the toilet seat 1 is placed at the down position, the portal vent 3 is opened to allow a continuous air from the toilet bowl cavity to be drawn through the system by the fan 16 to the outdoor. Thus, the foul odour air created within the toilet bowl cavity by the user in the bowel movement would be immediately drawn with the exiting air flow before it has time to saturate the air space within the toilet bowl. The space between the person's thighs forms the fresh air intake for the system and to allow the air to flow continuously therethrough. Even if a large person is sitting on the toilet seat to close completely the air intake, the air inside the toilet bowl above the water line prevents the creation of a vacuum in the toilet bowl. As the air with the obnoxious odour is removed immediately on being created, the suction power of the system can be maintained at the minimum specification so that a standard issue vent fan can quickly eliminate the odour.
The person simply flushes the toilet normally after having finished the bowel movement.
When the toilet seat is lifted to the up position, the air flow channel is blocked off, thus preventing possible water entry into the system by toilet bowl overflow, back splash and even vandalism or abuse of the device. Cleaning and maintenance are minimal. The underside of the toilet seat can be cleaned with household cleaners and bleach. The drain valve in the wall pipe allows for discharge of any built up condensation.
Although the preferred embodiment of the present invention has been disclosed and described in detail above, it should be understood that the invention is in no sense limited thereby, and its scope is to be determined by that of the following claims.
