Description

[0001] A COFFEE MAKER COMPRISING A NOZZLE

[0002] The present invention relates to a coffee maker comprising a nozzle.

[0003] In Turkish coffee makers, coffee is prepared by cooking the mixture of coffee and water. Some of the state of the art machines which are used to prepare Turkish coffee automatically adjust the water according to the amount of coffee to be prepared, while some machine require the user to add water into the brewing pot. The characteristics of the brewing technique can change the consistency and taste of the coffee. Foam formation during brewing is also very important for Turkish coffee. Since Turkish coffee is not a homogeneous coffee due to its form, the brewing technique is of great importance. Premixing coffee with water increases the homogeneity and improves the texture of the coffee. Various Turkish coffee makers are known in the art, which enable coffee to be brewed at optimum temperature without burning. The use of various sensors is known, which ensure the foam density in accordance with the coffee's brewing technique. Thus, coffee makers are available, which automatically end the brewing process when the coffee is ready or only function as a heater. However, since Turkish coffee is insoluble in water due to its form, the problem of clumping occurs when it comes into contact with water. Since the user cannot stir the mixture in the machines where the water is automatically adjusted, the mixture is brewed without stirring. When the coffee is brewed without stirring, the clumps therein remain undissolved, causing user dissatisfaction.

[0004] In the state of the art Patent Document No. TR201109954, a coffee maker is disclosed, comprising a mixer which is provided on the body and which can perform mixing during the brewing process.
