Claims:

I CLAIM:

1. A toilet odor fume Exhaust System comprised of: A. A sensor placed in a convenient position to detect a toilet user. B. The sensor will be connected to a timer and to an exhaust fan. Both of which will project into A wall cavity. The fan is to be located at the approximate toilet seat level of the toilet to be served. C. The odor fumes gathered by the exhaust fan are to be channeled outside either through the Stud wall cavity or through vent pipes according to local building codes. D. The timing device will be employed to time the deactivation of the exhaust fan at an adjustable Preset time interval.

BACKGROUND FOR PRESENT INVENTION

[0006] This invention pertains to the removal of toilet odors when a bath room toilet is used. At the present time there are many methods used to exhaust toilet odors. The most commonly used method is to exhaust toilet odor by use of an exhaust fan situated in the ceiling of the toilet area or room. There are other methods such as seat exhaust systems. Seats systems require cleanliness care and also require a certain amount of maintenance.

[0007] Until now, except continuously running systems, few exhaust systems are activated without manual touch. And, most exhaust systems permeate the toilet area with the toilet odors before these odors are removed.

SUMMARY OF THE INVENTION

[0008] The object of this invention is to provide an exhaust system which is activated and deactivated automatically by each toilet user. Another object is to provide an exhaust system which is inexpensive and easy to install. Another object is to be able to install this system in both existing toilet areas and in new construction using the house electrical system for the power source.

[0009] Another object is to use tried and tested sensors, exhaust fans and timers which are already in wide use. Another object is to provide an exhaust system which would require no special cleaning. And perhaps the most important object would be to provide a toilet exhaust system which would remove toilet odors before they permeated the toilet area or room.

BRIEF DESCRIPTION OF THE DRAWING

[0010] Page 1. Depicts a perspective view of a typical toilet area showing the placement of the exhaust system at the rear of the toilet. Note that the same placement may be used on either side lf a toilet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0018] The invention consist of three working parts (2,3 and 4)

[0019] 1. Typical Toilet

[0020] 2. A sensor, such as a PIR type, which can be placed in any convenient position to detect a user Of the toilet. The sensor will activate the exhaust fan.

[0021] 3. An Exhaust Fan Kit consisting of a fan, housing and grill. The fan should be sized for the area In which it will be used.

[0022] 4. The timer may be preset to deactivate the exhaust fan when the sensor detects that the toilet Is no longer in use.

[0023] 5. 6, 7. Are proposed exit locations for the toilet odor fumes being exhausted within the Stud Wall Cavity.

[0024] 8. Stud Wall Cavities which are used to channel the toilet odor fumes to the outside should Conform to the local building codes where used.

[0025] 9. Toilet odor fumes collected by the exhaust fan.
