Abstract
An electric coffee maker (2) comprises a first chamber (4), and a second chamber (6) arranged on top of the first chamber. A tube (8) extends down from the second chamber (6) into the first chamber (4) for transferring liquid between the two chambers. The base (20) of the first chamber (4) is provided with electric heater (24) and a thermally responsive control (46) is provided associated with the base (20) so as to be responsive to the temperature of the heater (24) or to a section of the base (20) for interrupting the power supply to or reducing the heating output of the heater (24).
Claims27
A beverage maker, comprising:
- a first chamber having a base that includes an electronic heating means and a control means;
- a second chamber arranged on top of the first chamber;
- a tube extending down from the second chamber into the first chamber for transferring liquid between the two chambers;
- wherein the control means is thermally responsive to the temperature of the electronic heating means or to a section of the base, and the control means is operable to interrupt a power supply to the electronic heating means or to reduce the heating output of the electronic heating means when a portion of the base of the first chamber boils dry;
- and
- wherein the portion of the base that boils dry is separated from the remainder of the base by a raised wall to define a reservoir of liquid that must boil away before the control means operates.
The beverage maker of claimed 7, wherein the electronic heating means comprises a sheathed heating element attached to an under side of the base.
A beverage maker, comprising:
- a first chamber having a base that includes a first reservoir and a second reservoir;
- a first reservoir heater disposed adjacent the first reservoir;
- a second reservoir heater disposed adjacent a second reservoir;
- a second chamber in fluid connection with the first chamber;
- a passage extending between the first chamber and the second chamber for transferring liquid between the two chambers;
- a controller that is thermally responsive to the temperature of the first reservoir heater or to the temperature of a section of the base, wherein the controller is operable to interrupt a power supply to the first reservoir heater or to reduce a thermal output of the first reservoir heater when the first reservoir boils dry.
