ABSTRACT:
A monitor embodiment, monitoring overflow levels in a bathtub, comprises an input water unit, including a control circuitry, coupled to a hot-cold water facet; a water level detection unit including telescopically joined tubes with a floatable lowest tube associated with an indicator, an uppermost tube fixed to the input unit, sensors attached to non-lowest tubes variably coupled. The sensors detect the indicator's position reaching a predetermined alarm or shutoff level, causing respective initiating an alarm signal, or terminating the input unit's water flow. Another embodiment additionally comprises an output water unit associated with the circuitry, incorporating a temperature sensor and a user preset-temperature selector. The output unit outlets cooled water from the bathtub, the input unit inlets hot water until the preset-temperature is reached, provided no alarm signal was issued. An additional sensor, incorporated in the input unit, allows adding the hot water when it's hotter than the bathtub water.
