[0002] Technical Field

[0003] The present invention relates to a coffee machine, more particularly to a coffee machine for grinding the coffee beans, weighting the amount of the grinded coffee and / or and water which are filled to the coffee pot in predetermined amount and cooking of Turkish coffee with the grinded coffee beans.

[0004] Background of the Invention

[0005] Nowadays, several automatic coffee machines are known to prepare coffees. In order to prepare Turkish Coffee, the mixture containing fresh grinded coffee beans and some water and / or milk in a pot should be heated slowly. In preparing Turkish coffee, the mixture in a pot is obtained with the addition of fresh ground coffee, sugar and water or milk with desired quantities, and the obtained mixture is stirred before the cooking process. In the state of the art, to achieve a traditional flavor and a froth appearance, said the coffee beans should be grinded and the mixture should be heated slowly and removed from the heater when the froth of the mixture reaches the desired level and / or height. Although there are several coffee machines with automatic stopping the heater depended on the proximity sensor which is evaluated of the froth of the mixture, the desired flavor and the appearance of the Turkish Coffee does not obtain.

[0006] The European patent document no. EP1763311B2 discloses a Turkish Coffee machine. Said coffee machine comprises a water tank, a water level sensor for detecting the water level, one or more boiling pot wherein the boiling process is performed, one or more pumps which convey the water to pots from the water tank, one or more proximity sensors detecting the existence of the pots, one or more infrared sensors which are set to detect the initial level of the mixture that is added to the boiling pot and one or more heaters which cut off energy transmission to the boiling pot immediately after the infrared sensor decides to end the boiling process.

[0007] As can be seen in the above-mentioned patent document, the ground coffee beans is added by the user, only the adding water and the heating process is provided automatically, and the energy of the heater is cut of depended on the level information achieved by the infrared sensors. Therefore, there is a coffee machine needs to achieve the desired flavor and appearance in a single cooking body by grinding the coffee beans, weighting the amount of the grinded coffee in grams to be put into the coffee pot, adding the water automatically in millimeters to coffee pot filled with grinded coffee and heating the mixture in a controlled manner for a predetermined time and to a self presetted height of cooking.

[0056] In the preferred embodiment of the invention, the infrared sensor (10) detects the existence of coffee pot (3) on the heater (4). The infrared sensor (10) aims to detecting the ending level of liquid in the coffee pot (3) to deactivate or stop the heater (4).

[0057] In the preferred embodiment of the invention, the lights (12) are LED and enlighten the inner body of the coffee pot (3). The colors of the light (12) indicate different cases about the boiling process. For instance, the activated red light (12) indicates the boiling process is continued; the activated green light (12) indicates the boiling process is finished and the coffee is ready for the user; the activated blue light (12) indicates the cooking base (5) is ready for the new cooking process. In the preferred embodiment of the invention, the colors are assigned to indicate each step of the cooking process. In the preferred embodiment of the invention the colors of the lights (12) can be changed by the user choices.

[0058] In the inventive coffee machine (1), the control panel (14) is a touch display and initiates first the filling of the coffee pots (3) with predetermined amount of grinded coffee and water. Control panel (14) ensures that the coffee pot (3) is filled with the predetermined grinded coffee and water weighted by scale (16). Control panel (14) is allowed users to choose and / or edit a preprogrammed coffee items and / or programs. Control panel (14) is allowed users to add or delete a preprogrammed coffee items and / or programs. Control panel (14) triggers the controller (15) to initiates the heater (4) for start the cooking process after the selection of coffee program and / or item. In the preferred embodiment of the invention, scale (16) is below the center of the drip tray. Scale (16) is connected to control panel (14) to share the weight of the coffee pots (3) with filled grinded coffee and / or water.

[0059] In the inventive coffee machine (1), the controller (15) is in communication with the control panel (14) and takes the selection information of users. The controller (15) holds the preprogrammed coffee programs and / or items of which coffee and water amount are predetermined. In another preferred embodiment of the invention, the controller (15) is backed up and restored the preprogrammed coffee items, cooking history and data history. The controller (15) triggers the coffee grinder (7) to grinding the beans with predetermined amount in according to coffee programs and / or items. The controller (15) activates the air-cooling mechanism of the grinder (7) optionally or within specifies time period. Thus, the taste of the Turkish Coffee is improved. The controller (15) also ensures the filling of boiling pot (3) with predetermined amount of water. The controller (15) accesses the weight information of the grinded coffee and water, added to coffee pot (3). Thus, the controller (15) controls the amount of the mixture comprising ground coffee and water. The controller (15) starts the boiling process after the coffee pot (3) is placed on one of the heaters (4). The controller (15) activates the heater (4) to start the boiling process in the coffee pot (3) containing the grinded coffee and water, and measure the desired and / or configured froth level / height and / or mixture level / height of the heating liquid with the infrared sensors (10). The controller (15) activates the light (12) and the air moisture blower (13) with the start of the heating process. In the preferred embodiment of the invention, the activated red light (12) indicates the boiling process is continued. Also, the air moisture blower (13) blows toward the boiling cup (13) during the boiling process. When the infrared sensor (10) detects the ending level is reached in the coffee pot (3), the controller (15) stops the cooking process and, turns off the light (12) at the same time and deactivates the air moisture blower (13) after the coffee pot (3) is removed.

[0060] In the inventive coffee machine (1) the controller (15) has more than one programmable coffee items / program. Firstly, the coffee pot (3) is placed below the grinded coffee output (8) and liquid output (9) and then control panel (14) takes the confirmation of the user’s selection and shares the confirmation information with the controller (15). The controller (15) decides the amount of coffee and / or water according to user selection of coffee program and / or item, and the predetermined amount of grinded coffee the falls to the coffee pot (3). The controller (15) also supplies the predetermined amount of water from the liquid output (9) to the coffee pot (3). The controller (15) checks the weight of the ground coffee-water mixture from the scale (16). The coffee pot (3) containing coffee and water is placed on the cooking base (5) and the infrared sensors (10) detect the presence of the coffee pot (3) is placed. The level sensor (10) detects the initial liquid level in the coffee pot (3) and shares said information with the controller (15), then the controller (15) activates the heater (4), the light (12) and the air moisture blower (13) together. The infrared sensor (10) reaches the ending level of liquid saved on the controller (15) and detects the preprogrammed ending level is provided or not. When the infrared sensor (10) detects the ending level in the coffee pot (3) is reached, the boiling process is stopped by the controller (15) and, the light (12) turns another color and after the coffee pot (3) is removed the air moisture blower (13) stops. In the preferred embodiment, the inventive Turkish coffee machine (1) is for professional usage.

[0061] It is possible to develop various embodiments of the inventive coffee machine (1); the invention cannot be limited to examples disclosed herein and it is essentially according to claims.
