Cooking system including a cooking hob and a cooking vessel

A cooking system including a cooking hob and a cooking vessel, the cooking hob comprising:

• a continuous glass or glass ceramic support plate having a treatment area capable of supporting the cooking vessel thereon;
• a lower magnetic coupling member rotatably arranged below said support plate at the treatment area;
• an electric drive motor operatively connected for rotating said lower magnetic coupling member;
• a first visual indication at said support plate indicating the position of said treatment area relative to the support plate;
• a second visual indication at the support plate indicating a predetermined angular position relative to said first visual indication;
• one or more hob components of detection means;
• and
• electronic control means connected to said hob components of detection means and to said electric drive motor;
• the cooking vessel comprising:
• a vessel wall;
• rotary blades installed inside the vessel wall;
• an upper magnetic coupling member connected to said rotary blades;
• an appendage attached to said vessel wall;
• and
• one or more vessel components of detection means located at said appendage, wherein:
• the one or more hob components of detection means cooperate with the one or more vessel components of detection means and with said electronic control means to allow the operation of the electric drive motor to make the upper magnetic coupling member rotate with the lower magnetic coupling member when the cooking vessel is located on the treatment area indicated by said first visual indication with said appendage at said predetermined angular position indicated by said second visual indication;
• and
• the one or more hob components of detection means do not cooperate with the one or more vessel components of detection means, and thereby the electronic control means modify or stop the operation of the electric drive motor, when the appendage of the cooking vessel is not located at said predetermined angular position indicated by said second visual indication.
