Water faucet with automatic temperature adjustment according to the user's request

Abstract

Water faucets that allow the user to manually mix hot and cold water until the desired temperature is felt have existed for a very long time. However, it typically can take up to a few minutes of various manual adjustments to get the desired temperature. Since the early 80's there existed also the possibility of doing the mixing automatically until a certain preselected temperature is reached, for example by an electric faucet with a temperature sensor. However, these patents did not solve the problem of the waiting time until the cold water in the hot water pipe gets out, and they did not solve the problem of reaching the desired heat if the hot water source is not hot enough and/or reaching the desired coldness of the cold water source is not cold enough. Clearly a more sophisticated system is needed. The present invention discloses an improved automated system that solves the above problems and creates an optimized combination, preferably in combination with at least one auxiliary temporary containment buffer and/or with an instant on-the-fly heater and/or a chilled water source.
