Abstract
A toilet reservoir fill alarm including water level sensors which can be positioned in the water reservoir tank of a flush toilet to detect the presence or absence of water at a desired level. A switch responds to the water level sensors and produces a control signal during the absence of a desired level. The control signal operates a timing circuit in order to produce an output signal at the termination of a predetermined time interval. Responsive to the output signal is an alarm circuit. In this manner, an alarm will sound should the toilet tank reservoir not refill during the predetermined time interval following the flushing of the toilet.
Claims19
A toilet reservoir fill alarm system comprising:
- electronic water level sensing rods for positioning in the water reservoir tank of a flush toilet so as to at least partially extend into the water when at a desired level, and detecting the presence and absence of water at said desired level in the reservoir tank;
- level adjusting means for adjusting the depth of extension of said sensing rods into the water tank so as to adjust said desired level;
- switch means responsive to the water level sensors for providing a control signal during the absence of a desired level of water and terminating said control signal upon the presence of a desired water level;
- capacitor timing means operative for charging up during the presence of said control signal and triggering a switch means after a predetermined time, the switch means producing an output signal at the termination of said predetermined time interval;
- alarm means responsive to said output signal whereby said alarm means will sound should a toilet tank reservoir not refill during the predetermined time interval following flushing of the toilet;
- and
- short circuit means for shorting out said capacitor timing means upon termination of said control signal prior to said predetermined time interval, whereby said alarm system is immediately available for further monitoring usage.
A toilet reservoir fill alarm, comprising:
- a portable housing;
- mounting brackets on said housing for mounting said housing externally of the water reservoir tank of the flush toilet;
- electronic water level sensors for detecting the presence and absence of water at a desired level in said reservoir tank;
- support means for adjustably supporting said sensors from said housing and retaining them internally of the reservoir tank so as to extend into the water contained in the tank;
- and
- circuit means contained in said housing and coupled to said sensors and comprising timing means for timing a predetermined time interval after said sensors detect the absence of water at the desired level, alarm means for providing an alarm signal after said predetermined time interval, means for continuously sounding said alarm means even after refilling of the tank, and manual reset means for resetting said alarm means.
