Description
PORTABLE TOILET BOWL VENTILATOR
INTRODUCTION
This invention relates to the controlling of offensive odors from a toilet bowl by ventilation. More specifically the ventilation is provided by a battery-powered fan a~dLus that vents the odors through a tube that traverses the water trap in the toilet to vent the odors into the sewer vent pipe. Thus the al~p~dllls of this invention may be inserted in any siphon-type toilet, requires no technical in~t~ tion, and may be removed to be carried to another toilet.
CA 02223~23 1997-12-04 W O ~7/00359 PCTAUS96/10585 BACKGROUND
Nunl~;lvus i"vel~tc~l~ have provided ventilation for a toilet bowl. Such inventions have been incorporated in the body of the toilet bowl, in the seat and lid of the toilet, and as ~tt~rhm~-nt~ to the rim of the toilet bowl. Many of these prior inventions rely upon an adsorbent mP~ m, such as activated carbon, to remove orr~,n~ivt; odors from the air drawn from the toilet bowl. Other of these prior inventions vent the air Co~ the offensive odors directly outside or through the wall of the room in which the toilet facility is placed. Some of these prior art devices even vent the air coll~ the offensive odors into the sewer vent pipe (often called the "stack") required by building codes in all sanitary sewer in~t~ ti~ns.
All of the prior art devices of which applicant is aware require special modifications to the toilet or its environs. Special seats or special lids. Special water tanks or lids therefor. Special toilets having built-in vent lines. Vent holes in walls.
All are perm~nent in~f~ tions applied to a particular toilet. None has been seen that are transportable for use with more than one toilet.
Thus, it is seen that there is a need for a portable device that is usable in any one of a plurality of toilets and that requires no p~rm~n~nt inct~ tion and may easily be inserted into any toilet for use. Such a device could be carried by anindividual to be used in any siphon toilet facility the individual may visit.

CA 02223~23 1997-12-04 DETAILED DESCRIPTION OF THE INVENTION
This invention will be most easily understood by referring to the attached drawings, wh~ parts are i~lentifie~l by reference numbers con.eietPnt with the following description. In each view, the same part carries the same reference number.
Figure 1 illu~llates a siphon toilet 11 ofthe type in common use and shows the present invention 20 installed therein. This type of toilet is often called a flush toilet. The mech~niem by which this type of toilet op~ .ales is to m~int~in a level of water in the bottom of the bowl 12 and in an upwardly-directed recurve drain portion 27 ofthe toilet with which the bowl 12 is in direct c-mmllnication, thereby forming a barrier to gases in the sanitary drain line 16 that communicates with a sewer or septic tank, which gases could otherwise enter the living quarters where the toilet is installed. In this normal or rest condition, two surfaces are present: one is within a recurve drain portion 27 of the toilet and the other is within the bowl 12 of the toilet.
When the bowl 12 is rapidly filled with a quantity of water from a flush tank or flush valve, the water level in the bowl 12 and in the recurve drain portion 27 rises until the level in the drain portion overflows into the drain line 16, wllt;le.~on it causes a siphon effect to more rapidly empty the bowl 12 and its contents of waste and water.
When the water supplied to the bowl 12 slows, the water level in the bowl drops to a level low enough that air may be drawn into the recurve portion of the drain, thereby to break the siphon effect and allow water to again fill the bowl 12 to substantially the original level, thereby to again form a very effective seal against sewer gases.
It is well known that unpleasant odors in a bathroom can come from the toilet, especially when it is in use. Previous inventors have long recognized the desirability of elimin~ting these odors where they are most conc~ dled and before they are dispersed in the room air. Some of these inv~stig~tors have chosen to vent the malodorous air into the drain lines of the building in which the toilet is installed.
Previous investigators, however, did not anticipate the desirability of a traveler carrying equirm~nt with him to the toilet for easy inet~llin~ and removing. Modern CA 02223~23 1997-12-04 W O 97/00359 PCTrUS96/10585 motors and portable power supplies in the form of batteries or safe adapting of household elçctri~l current to bathroom use offer safety and convenience that had not been available in the past. Further, individuals now are more aware of the ~lçsir~bility to not allow foul odors to p~rm~te their homes, even in toilet areas. t The present invention adapts what has been known about odor removal from the toilet bowl and makes it portable and easy to install or, more correctly, to insert.
It is clear from Figure 1 that the air space at 25 is in co",."-.llic~tion via drain line 16 with air in a vent pipe 15, which is open to the ~tmosphere for venting gases from the drain plumbing 13 in the building in which the plumbing is installed. The invention 20 comprises a fan to force air from the toilet bowl 12 into the air space 25 and thence to the vent pipe 15, thereby to prevent foul odors from the toilet from dispersing into the environs of the toilet.
Figure 2 shows a detailed view of the invention 20 in one embodiment, comprising: a fan 30 having a fan housing 32 that has an inlet opening 34 and anexhaust opening 36; a flexible tube 40 connected to exhaust opening 36 for carrying the exhaust from fan 30; and a supporting bracket 44 attached to fan housing 32 and adapted to engage the rim of the toilet in a removable manner, thereby to suspend said fan below said rim within said bowl in a removable manner. In use, tube 40 extends through both said water surfaces while fan inlet opening 34 is within bowl 12, thereby to draw by forced convection air from bowl 12 and exh~llct that air into the s~ drain system 13. Clearly, the tube 40 must be flexible enough to be bent within the ~u. v~ e of the water trap, yet not be so limp as to not be capable of being pushed into the proper position. Many plastic materials are suitable for this tube. Anyone skilled in the art could select a suitable m~tPri~l The power for the fan shown in Figure 2 is llltim~t~ly electricity from a household receptacle, though the voltage may be reduced through an isolation tr~n~former (not shown) for safety.
Shown on the end of tube 40 in Figure 2 is a simple one-way valve 48 that only permits flow out of the tube. This valve keeps water from ~nt~ring the tube 40 CA 02223~23 1997-12-04 W O 97/00359 PCT~US96/10585 as the tube is inserted into the water in the toilet bowl 12. The valve 48 shown is of a type commonly used to permit c-)n~l~n~te to drain from air lines that operate below atmospheric pres~u e, as in automobile air conditioning eqllipment The valve is made of soft plastic or rubber-like m~t~ri~l and shaped to fit onto a round tube at its S upper end 50 and is flattened at its lower end 527 leaving only a slit as an opening.
Any back flow is prevented by closing of the slit caused by reverse p~CS~ulc that would create such back flow. A side view of valve 48 is shown as Figure 3.
Figure 4 shows the invention in another embodiment, including the fan housing 32, a fan motor 33, a bracket 44 adapted to rest on the rim of a toilet bowl, and a housing 56 for a battery suspended outside the bowl 12. Wires to carry electrical energy from the battery within the battery housing 56 and the fan motor 33 are present but not shown.
Figure 5 shows the invention in yet another embodiment, including the fan housing 32, a fan motor 33, a bracket 44 adapted to rest on the rim of a toilet bowl, and a housing S6 for a battery ~u~olLcd inside the bowl 12. In this example, housing 56 and housing 32 are ~tt~ h~ , or contiguous. This need not be the case, as housing 56 and housing 32 are clearly non-contiguous in Figure 4. Wires to carry electrical energy from the battery within the battery housing 56 and the fan motor 33 are present but not shown.
Having described this invention, including the citing of functional specific ~x~mplec thereof, applicant desires to include within the scope of his invention those improvements that would be imrnediately obvious to one skilled in the art, some, but not all of which illl~lovelllents may have been referred to herein. Applicant desires the breadth of his invention to be limited only by the scope of the claims appended hereto.
