Water flow and temperature controller for a bathtub faucet
First Claim
1. In combination with a bath tub or shower assembly having hot and cold water supply lines both in communication with a shower head and bath tub faucet, a water flow and temperature controller comprising:
- a controller means;
a control valve disposed on said hot and cold water supply lines each operable betweena fully opened and closed position and each in communication with said controller means;
a temperature sensor disposed within said faucet and said shower head for measuring the temperature of water exiting therefrom, each of said sensors in communication with said control assembly whereby said controller manipulates said control valves to maintain water exiting said shower and said faucet at a preselected temperature;
a hollow mixing chamber having an interior, a pair of inlets and an outlet each in communication with said interior, a first inlet in communication with said hot water supply line and a second inlet in communication with said cold water supply line;
said chamber having first section with an impeller disposed within said first section, said impeller hydraulically rotatable by flow of said hot and cold water to thoroughly mix hot and cold water flowing thereto.

Abstract
A temperature and flow controller for a bath tub or shower is disclosed. The device includes a panel that replaces or surrounds the standard bath tub water valves. Within the panel is a control assembly in communication with temperature sensors in the shower head and the bath tub faucet as well as control valves on the hot and cold water supply lines. The temperature sensors are immediately downstream from a unique, two stage mixing chamber having a rotatable impeller in a first section and a helically grooved inner surface in a second section to thoroughly mix hot and cold water therein. The controller also includes means for enabling water flow at a preset time of day, for a predetermined duration or to deliver a predetermined volume of water.
