Odor control ventilator

A ventilator for toilets comprising the combination of a toilet bowl, a water tank for flushing the toilet bowl, the water tank having a cover, a discharge conduit extending from said tank, a flush valve controlling the flow of water from the tank into said conduit, and an overflow pipe connected into said discharge conduit below the valve, said toilet bowl having a water distribution channel in communication with said discharge conduit for distributing water from said tank into said bowl, an electrically driven suction device, means connecting said electrically driven suction device to the inside of said tank above the normal water line therein, and control means for supplying electric power to and removing electric power from said electrically driven suction device, said control means including air sensitive means responsive to air within said tank for automatically removing power from said electrically driven suction device when said flush valve is operated to flush said bowl said control means also including a starting circuit having a power control switch therein and a sequence detecting means for preventing operation of said electrically driven suction means until said power control switch has been operated in accordance with a predetermined sequence of on-off operations.

For use in connection with the bowl and water tank of a toilet, said tank being adapted to receive odor laden air from said bowl, said tank having an air space at the upper portion thereof, a ceiling above the tank and an air space above the ceiling;

• a bathroom accessory comprising the combination of a towel pole and toilet ventilator, said towel pole comprising a hollow vertical tube having towel holders suitably attached thereto, the lower portion of said hollow vertical tube being operatively connected into the air space of the water tank of said toilet so as to form a substantially airtight passage from said air space into the bore of said hollow vertical tube, said hollow vertical tube or extension thereof passing through the ceiling above said toilet, air blower means operatively connected into the bore of said hollow tube or extension thereof which passes through said ceiling, whereby odor laden air may be drawn from said toilet, through the bore of said towel pole, and discharged to atmosphere, said towel pole also serving as a towel holder.

For use in connection with a toilet including toilet bowl provided with flushing means, and a water tank adapted to receive odor laden air therefrom, said water tank having an air space at the upper portion thereof, air blower means having a suction inlet, and an outlet discharging into the atmosphere;

• an improved toilet ventilator accessory comprising an air duct operatively connected into the air space within the water tank of said toilet, and also operatively connected to the suction side of said air blower means so as to reduce the air pressure within said water tank, air sensor means capable of sensing the air pressure within said water tank or the rate of air flow through said air duct, electrical switching means controlled by said air sensor means and capable of removing power from said air blower means, whereby odor laden air may be drawn in seriatim from the bowl of said toilet, through the overflow pipe of said water tank, through said air duct, and suitably discharged into the atmosphere by said blower means, and whereby the combination of said air sensor means and said switch means removes electrical power from said blower means when said toilet is flushed, said air sensor means being responsive to the sudden decrease in air pressure within said water tank or to the sudden decrease in air flow through said air duct when said toilet is flushed.

For use in connection with a toilet including a toilet bowl having flushing means and a water tank for supplying water to said bowl, said tank having an upper space for receiving odor laden air from the bowl, and air blower means discharging into atmosphere and having a suction inlet;

• an improved toilet ventilator accessory comprising an air duct suitably connected into the air space within the water tank of said toilet, said duct being also suitably connected to the suction inlet of said air blower means so as to reduce the air pressure within said water tank, electrical control means capable of removing power from said air blower means when said toilet is flushed, and braking means capable of rapidly slowing said air blower means when said toilet is flushed, whereby odor laden air may be drawn in seriatim from the bowl of said toilet, through said duct, and suitably discharged into the atmosphere by said air blower means, and whereby said braking means permits the rapid repressurization of the air within said water tank so as to allow a normal rapid flushing action.
