Abstract
A system is disclosed for dispensing a liquid at a desired temperature from a hot liquid pressure line and a cold liquid pressure line to a plurality of liquid outlets such as a bathtub, a sink or the like. The system controls the temperature of the liquid flowing from the plurality of liquid outputs as well as controlling the level of liquid within a container and for maintaining the temperature of the liquid therein. The system includes a liquid recycling system which reduces the amount of liquid discarded during the operation of the system and to converse heat energy. The system is controlled by a novel electronic control which when applied to a water dispensing system is able to control all functions of a bathtub as well as being capable of controlling a sink, a toilet or the complete water system for a residence, a hotel, an industrial or a medical complex or the like. The system also includes novel valve means for providing liquid mixing, liquid flow control, liquid distribution and diverting, liquid draining and liquid eduction which may be useful in many liquid distribution systems independent of the examples of the liquid dispensing system set forth herein.
