A COOKING DEVICE COMPRISING A COOKING STONE

Description

[0001] The present invention relates to a cooking device comprising a cooking stone.

[0002] In ovens, the cooking process is performed by dissipating the heat generated by the heater into the cooking device by means of the fan. The cooking process is performed by dissipating the hot air into the cooking device. Therefore, foodstuffs are cooked by means of air without getting into contact with a hot surface. This causes difficulties in cooking dough foods such as pizza, etc., and the cooking process takes a long time. This causes the dough to harden or fail to be cooked as desired. In the state of the art cooking stones for cooking dough foods are used. Generally the state of the art cooking stones are produced from refractory materials, such as ceramic or stone, which have a high capacity of storing heat and releasing the heat slowly over time, thus allowing to directly heat the base of the dough food which is in contact with the tray. However, the cooking stones which are used frequently get dirty in the course of time. As the dirt accumulates on the surface, the cooking process cannot be performed with high efficiency, causing the foodstuffs to be undercooked or overcooked. The cooking stones have to be cleaned by the user at certain intervals. However, the need for continuously cleaning the cooking stones causes difficulty of use. Therefore, in the state of the art, cooking devices which performing the washing process are known. The washing process is performed by means of the spraying members which can spray water into the cooking chamber. However, the accumulation of dirty water on the cooking stone during the washing process causes problems of hygiene, and in the long term, forces the user to perform the cleaning process. This causes difficulty of use.
