Bath water control system
First Claim
1. A bath water control system for controlling water flow to a personal bath unit including a bath drain and comprising:
- mixing valve means having a hot water input, a cold water input, and a mixed water output and responsive to a control input for supplying a selected mixture of hot and cold water at said mixed water output;
actuator means responsive to both a selected temperature signal and a signal representative of the temperature of water from said mixed water output, for providing said control input to said mixing valve means;
at least one fluid passageway having an input connected to said mixed water output and having a passageway output; and
control means for providing a said selected temperature signal to said actuator means and comprising;
memory means for storing at least one selected temperature signal,readout means for selectively sensing one of said selected temperature signals and providing it as a selected temperature signal to said actuator means,temperature adjustments means coupled between said program selection means and said actuator means for selectively varying said selected temperature signal,second D memory means for storing at least one selected time duration signal representative of a discrete time period, andsaid program selection means further includes means in circuit with said actuator means and said second memory means for selectively sensing a said time duration signal together with a said selected temperature signal and providing said selected temperature signal to said actuator means for a said discrete time period.

Abstract
A bath water control system in which the bath water is selectively supplied a bath or shower outlets, and the water supply is as to both temperature and period of supply. These parameters may be prestored in a memory along with discrete start times whereby a programmed bath will be automatically available at a discrete time or times in the future. As a means of ensuring that water is not accumulated in the tub prior to water temperature rising to a selected value, the tub drain is closed only after input bath water reaches a selected temperature. Further, means are provided for turning off water in the event that water in excess of a selected value appears. Still further, the temperature of water is indicated both digitally and aurally.
