Claims11
In a conventional tank-type toilet having a toilet bowl, a tank, and a plumbing system with a water flow connected to the tank, the improvement comprising a water-actuated toilet fan connected to the plumbing system and to the tank, for the recirculation of the air, in the vicinity of the toilet exteriorly thereto, the toilet fan including:
- a housing external to the toilet having a water compartment and an air compartment;
- intake means connected to the plumbing system and to the water compartment of the housing for intake of the water flow for the toilet from the plumbing system;
- rotation means in the water compartment for transferring energy from the water flow through the water compartment into rotational motion;
- air recirculation means in the air compartment connected to the rotational means for transferring the rotational motion from the rotation means to an air flow, wherein the air compartment, is vented and has an opening for air flow leaving the air compartment the toilet fan including deodorization means for deodorizing air flow leaving the air compartment of the toilet fan;
- and
- outflow connection means connected to the water compartment of the housing for directing the water flow out of the toilet fan and into the tank.
In a conventional tank-type toilet having a toilet bowl, a tank, and a plumbing system with a water flow connected to the tank, the improvement comprising:
- a water-actuated toilet fan connected to the plumbing system and the toilet, for the recirculation of the air in the vicinity of the toilet exteriorly thereto, the toilet fan including:
- a housing external to the toilet having a water compartment and an air compartment;
- a water-wheel in the water compartment with an axis of rotation that transfers energy from the water flow through the water compartment into rotational motion;
- a shaft attached to the water wheel along the axis of rotation of the water-wheel that rotates at the same frequency as the water-wheel, the shaft extending from the water compartment into the air compartment;
- a fan in the air compartment attached to the shaft that rotates at the same frequency as the shaft, wherein an air flow is generated by the rotating fan;
- air deodorization means in the air compartment for deodorizing air flow from the air compartment;
- and
- an outflow connector on the housing at the water compartment connecting the housing to the toilet tank, wherein the water flow through the water compartment is directed into the toilet tank through the outflow connector.
