1. A variable temperature control assembly, for use in a water dispenser having a water dispensing nozzle through which an amount of water at a user-specified temperature is dispensed, comprising:
a variable temperature selector having a range of available temperatures for a user to select a specific temperature for the amount of water at a user-specified temperature to be dispensed through the water dispensing nozzle;
a hot water system in communication with the water dispensing nozzle, comprising a hot water tank, at least one hot water temperature sensor and a hot water solenoid, wherein the hot water solenoid is in communication with the hot water tank and, in use, the hot water tank holds a supply of hot water having a present temperature measured by the at least one hot water temperature sensor;
a cold water system in communication with the water dispensing nozzle, comprising a cold water tank, at least one cold water temperature sensor and a cold water solenoid, wherein the cold water solenoid is in communication with the cold water tank and, in use, the cold water tank holds a supply of cold water having a present temperature measured by the at least one cold water temperature sensor;
an ambient water system in communication with the water dispensing nozzle, comprising an ambient water tank, at least one ambient water temperature sensor and an ambient water solenoid, wherein the ambient water solenoid is in communication with the ambient water tank and, in use, the ambient water tank holds a supply of ambient water having a present temperature measured by the at least one ambient water temperature sensor;
a processor, in communication with the variable temperature selector, the at least one hot water temperature sensor, the hot water solenoid, the at least one cold water temperature sensor, the cold water solenoid, the at least one ambient water temperature sensor and the ambient water solenoid; capable of retrieving the present temperature of the hot water in the hot water tank from the at least one hot water temperature sensor, capable of retrieving the present temperature of the cold water in the cold water tank from the at least one cold water temperature sensor, capable of retrieving the present temperature of the ambient water in the ambient water tank from the at least one ambient water temperature sensor, capable of calculating a ratio of an amount of hot water from the hot water tank, an amount of cold water from the cold water tank and an amount of ambient water from the ambient water tank to be mixed together to produce the amount of water at a user-specified temperature at the specific temperature selected by the user and capable of simultaneously sending signals to the hot water solenoid to dispense the amount of hot water from the hot water tank, to the cold water solenoid to dispense the amount of cold water from the cold water tank and to the ambient water solenoid to dispense the amount of ambient water from the ambient water tank at the calculated ratio of the amount of hot water, to the amount of cold water, to the amount of ambient water needed to be mixed together to produce the amount of water at a user-specified temperature at the specific temperature selected by the user; and
wherein, in use:
the user selects from the range of available temperatures on the variable temperature selector a temperature at which the amount of water at a user-specified temperature is to be dispensed through the water dispensing nozzle
the user selected temperature is communicated to the processor;
the processor retrieves the present temperature of the hot water in the hot water tank from the at least one hot water temperature sensor, retrieves the present temperature of the cold water in the cold water tank from the at least one cold water temperature sensor and retrieves the present temperature of the ambient water in the ambient water tank from the at least one ambient water temperature sensor;
using the retrieved present temperatures of the hot water in the hot water tank, the cold water in the cold water tank and the ambient water in the ambient water tank, along with the user selected temperature, the processor calculates a ratio of an amount of hot water from the hot water tank, an amount of cold water from the cold water tank and an amount of ambient water from the ambient water tank to be mixed together to produce the amount of water at a user-specified temperature at the specific temperature selected by the user;
the processor simultaneously sends signals to the hot water solenoid to dispense the amount of hot water from the hot water tank, to the cold water solenoid to dispense the amount of cold water from the cold water tank and to the ambient water solenoid to dispense the amount of ambient water from the ambient water tank at the calculated ratio of the amount of hot water, to the amount of cold water, to the amount of ambient water needed to be mixed together to produce the amount of water at a user-specified temperature at the specific temperature selected by the user.
