Abstract

A toilet assembly having an automatic flushing system comprising a toilet bowl having a toilet cover, the toilet cover containing a window disposed therein, a water holding tank operatively associated with the toilet bowl, the holding tank containing structures for storing water, discharging water into the toilet bowl and a replenishing water to the water holding tank, and motion sensing device positioned within the water holding tank and aligned with the window in the toilet cover, when the toilet cover is in a raised position, the motion sensing device being angled in a downward direction from the horizontal, so that any reflection of beams from the motion sensing device against the window in the toilet cover is not received by the motion sensor and thus does not activate the motion sensor.

Claims

1. A toilet assembly having an automatic flushing system which comprises:

a toilet bowl having a toilet cover, said toilet cover containing a window disposed therein,

a water holding tank connected to said toilet bowl, said holding tank containing operative means comprising means for storing water, discharging water into the toilet bowl and replenishing water to the water holding tank, and

motion sensing means operatively connected to said operative means associated with the water holding tank and aligned with the window in the toilet cover, when said toilet cover is in a raised position, said motion sensing means being angled in a downward direction from the horizontal, so that any reflection of beams from the motion sensing means against the window in the toilet cover is not received by the motion sensor and thus does not activate the motion sensor.

2. The toilet assembly of claim 1, wherein the motion sensor has an element for sending beams and an element for receiving beams whereby the beams reflected from the window of the toilet cover are deflected so as not to activate the motion sensor.

3. The toilet assembly of claim 1, wherein a mechanism is provided within the water holding tank for performing the normal flushing function of the toilet system and refilling of the toilet bowl with water.

4. The toilet assembly of claim 3, wherein a manual flushing system is operatively connected to said flushing function of the toilet system.

5. The toilet assembly of claim 1, wherein the motion sensing means is provided with a convex lens for collecting the beam and preventing it from scattering.

6. The toilet assembly of claim 1, wherein the operative means includes a plurality of gears operatively interconnected with each other and with said water discharge means and said water replenishing means, said plurality of gears being driven by a motor which, in turn, is operatively connected with said motion sensing means.

7. The toilet assembly of claim 1, wherein a manual flush means is operatively connected with said operative means for manually operating the toilet assembly.
