A coffee maker comprising
- a. a top housing (2) connected to a bottom housing (3) via a plurality of connecting elements (4) such that the top housing is enacted above the bottom housing;
- b. a water tank (1) positioned on top of the top housing;
- c. a carafe (5) to be placed under said top housing, said carafe comprises an upper part having a brewing cone (51);
- and
- d. a rotating spout (6) located at the bottom of said top housing and above said carafe for pouring hot water into said carafe;
- wherein the water tank comprises a heating system, a valve and a temperature sensor, wherein when said temperature sensor detects a specified temperature, said heating system is turned off and said valve is opened to allow hot water flowing via said rotating spout;
- wherein said valve is controlled by a gear system comprising a first cam and a second cam, the gear system rotates under the control of a motor gear system comprising a motor, a micro switch, and gears;
- wherein said temperature sensor is configured to turn the heating system on or off to keep water in said hot water chamber(s) at 92° C. to 96° C. and said motor gear system is configured to begin to rotate at the same time when the heating system is turned on or off to control opening or closing of said valve, the motor gear system is configured to stop rotating when the micro switch is hit by said first cam integrated in the gear system;
- wherein said valve is configured to open when said second cam integrated in the gear system activates a valve piston of said valve, and said water at 92° C. to 96° C. is configured to flow immediately from said water tank to the filter basket by gravity via the said rotating spout, said water configured to directly contact ground coffee to extract coffee beverage.
