Abstract

The two-piece electric coffee maker includes a Dallah (a traditional Arabian coffee pot for making Arabian coffee) and an electric stove. The coffee pot has a temperature sensor that extends from the base of the coffee pot handle into the pot. The base of the handle also has an electrical connector extending downward from the handle. The electric stove has a housing, a ceramic heating element or plate, a display console, and a mating electrical connector facing upward so that the connectors engage each other when the pot is placed on the heating element. An electronic control unit in the stove housing regulates boiling water for the coffee, reducing the heat after the water has started to boil, annunciating an alarm signal when the temperature of the water is suitable to add coffee grounds to the pot, and monitors brewing time for the coffee.

Claims

1. A coffee maker, consisting of:

a pot having a closed base, an opened top, and a wall defined between the closed base and the opened top;

a lid hingedly mounted to the opened top of the pot;

a spout extending from the wall of the pot having a mouth;

a handle disposed on wall of the pot opposite the spout;

a strainer disposed within the pot, adjacent to the spout at an inlet of the spout, the pot having tracks disposed therein on opposite sides of the inlet to the spout, the strainer being a flat, perforated plate slidably received in the tracks; and

having a handle extending from the flat plate;

a sensor assembly having at least a temperature sensor and a liquid level sensor disposed in the pot adjacent the base;

a first electrical connector extending downward from the handle, the first electrical connector and the sensor assembly being electrically coupled;

a stove housing including a ceramic hot plate mounted on the stove housing;

a second electrical connector mounted on the stove housing adjacent the ceramic hot plate, the second electrical connector facing upward, and being designed and configure for mating with the first electrical connector when the pot is placed on the ceramic hot plate;

a console mounted on the housing having a plurality of indicator lights and control buttons;

the control buttons include an On/Off button, a Start button, and a Keep Warm button;

the indicator lights include an LCD display connected to the control unit displaying temperature and time, a Finish indicator, and an Add light;

a control unit mounted in the housing of the stove base and coupled to the second electrical connector, the control buttons and indicator lights, the control unit comprises a memory module, and a processor selected from the group of microprocessor, microcontroller, and digital signal processor;

wherein the control unit receives the sensor assembly signals transmitted through the first and second electrical connectors, controls the ceramic hot plate to generate a predetermined amount of heat to the pot, and activates and deactivates the indicator lights on and off; and

an annunciator connected to the control unit for emitting an audible alert for indicating when water in the pot has boiled, when the water in the pot has cooled to a predetermined temperature, when the liquid level falls below a predetermined threshold, and when a predetermined brewing time has been reached.
