Abstract:
1. A mixing faucet system for an aircraft comprising: a discharge unit of hot and cold water disposed on a wash basin in a lavatory unit of an aircraft; and a supply unit separated from the discharge unit and disposed at a remote location from the wash basin for supplying cold water and hot water taken therein either independently or in a mixed state to the discharge unit through a connecting pipe, wherein the discharge unit includes a temperature control means for controlling the temperature of the hot and cold water being discharged, the supply unit includes a cold water intake and hot water intake for taking in cold water and hot water independently, and a mixing means for mixing the cold and hot water, a first chamber and a second chamber independently connected between the cold water intake or the hot water intake and the mixing means, respectively, each having an air reservoir portion formed in the interior of the chamber, and a third chamber disposed on an outlet side of the mixing means connected to the connecting pipe, having an air reservoir portion formed in the interior of the chamber, the mixing means includes a first solenoid valve and a second solenoid valve each respective connected to the cold water intake and the hot water intake, a control signal reflecting the temperature designated via the temperature control means of the discharge unit is sent via a control wire to the mixing means of the supply unit, and the water temperature of the mixed water is controlled by varying the respectively duty ratios of the first solenoid valve and the second solenoid valve according to the designated temperature, wherein the mixing means includes an upper block and a lower block vertically fit to one another at a projection and a recess in a liquid-tight state and in a mutually displaceable manner, wherein each connecting channel is extended vertically across the upper block and the lower block in the projection and the recess.
