A coffee-maker is provided which comprises a first supply voltage terminal (10) and a second supply voltage terminal (11), a heating element (12), a first switching element (13), and a second switching element (14), which heating element (12), first switching element (13) and second switching element (14) are serially coupled between the first supply voltage terminal (10) and the second supply voltage terminal (11), the first switching element (13) being adapted to set the heating element (12) to a first keep-warm temperature and the second switching element (14) being adapted to set the heating element (12) to a second keep-warm temperature. For an improved control to set the heating element (12) to the first and the second keep-warm temperature, the second switching element (14) is adapted to set the heating element (12) to the second keep-warm temperature depending upon a time needed to establish the first keep-warm temperature.
A coffee-maker having a BREW state in which a temperature is generated by a heating unit for the purpose of making coffee, a first KEEP-WARM state and a second KEEP-WARM state in which a temperature is set to keep brewed coffee warm, said coffee-maker comprising a first supply voltage terminal(10) and a second supply voltage terminal (11), a heating element (12), a first switching element (13), and a second switching element (14), which heating element (12), first switching element (13) and second switching element (14) are serially coupled between the first supply voltage terminal (10) and the second supply voltage terminal (11), the first switching element (13) being associatively adapted to set the heating element (12) to a first KEEP-WARM temperature to establish the first KEEP-WARM state and the second switching element (14) being associatively adapted to set the heating element (12) to a second KEEP-WARM temperature to establish a second KEEP-WARM state wherein the heating element (12) functions responsive to the first switching element (13) to establish the first KEEP-WARM temperature within a first period of time, T1, and the second switching element (14) is associatively adapted to set the heating element (12) to the second KEEP-WARM temperature after T1 has elapsed and the first KEEP-WARM temperature is established.
