Cooking appliance with a pan and a method for cleaning the pan

A method for cleaning residues from a cooking space of a cooking appliance suitable for the cooking of food products, comprising the steps of:

• (a) providing the cooking appliance, the cooking appliance comprises:
• a pan having inside walls having a front wall, a rear wall, two side walls, and a bottom, the inside walls forming an interior space, the interior space being a cooking space, said cooking space being open to an upside;
• a lid, which serves to close the cooking space, and forms the upside wall of the cooking space when closed;
• a drain, which is formed in the bottom of the pan and which can be closed or used to discharge liquid in particular from the cooking space when desired;
• and
• at least one rotatable spray nozzle, the at least one rotatable spray nozzle introducing a liquid jet under high pressure into the cooking space, the at least one rotatable spray nozzle being mounted on a rotatable spray head for introducing the liquid jet into the cooking space, the at least one rotatable spray nozzle rotates around an axis perpendicular to a rotational axis of the rotatable spray head rotating around the rotational axis;
• (b) placing food products in the cooking space from the upside of the cooking space into the interior space;
• (c) cooking the food products with the cooking appliance, the food products being in direct contact with the inside walls during cooking;
• (d) closing the drain and adding a cleaning agent to the cooking space after the step of cooking the food products with the cooking appliance and also after the food products have been removed from the cooking space;
• (e) introducing the liquid jet under the high pressure from the rotatable spray head through the at least one rotatable spray nozzle into the interior space while the at least one rotatable spray nozzle rotates around the axis perpendicular to the rotational axis of the rotatable spray head rotating around the rotational axis, the liquid jet consists exclusively of water, and after this agent has been allowed to work for a certain period of time, the liquid jet swirls and splashes the cleaning agent within the cooking space onto the walls and the inside surface of the closed lid, the liquid water jet together with the cleaning agent forming a washing solution;
• (f) allowing the cleaning agent to work for a further certain period of time and opening the drain and again introducing the liquid jet under the high pressure from the rotatable spray head through the at least one rotatable spray nozzle into the interior space while the at least one rotatable spray nozzle rotates around the axis perpendicular to the rotational axis of the rotatable spray head rotating around the rotational axis, said liquid jet under the high pressure removes the residues mechanically from the bottom, the walls, and the inside surface of the lid together with the splashed washing solution;
• (g) carrying away the washing solution containing the removed residues during and after step (f) out of the cooking space via the drain;
• and
• (h) repeating step (f) one or more times in succession.
