Abstract

A cooking appliance includes a heater, a blower, a steam generator, a cooking chamber, a cooking chamber drain, a steam condenser and a cooking appliance drain, and the steam condenser is arranged between the cooking chamber drain and the cooking appliance drain. A fluid from the steam generator and from a washing liquid reservoir, which fluid includes water, a cleaning agent, a rinsing agent, a wetting agent, a decalcification agent and/or waste products arising when cooking a product in the cooking chamber can be distributed in the cooking chamber for the cleaning of the chamber. A washing liquid reservoir is preferably filled at least partially by a step-by-step method of at least partial over-filling of the steam generator with water, and the washing liquid from the washing liquid reservoir, which liquid includes water and a cleaning agent, a rinsing agent, a wetting agent, a decalcification agent and/or waste products arising when cooking a product in the cooking chamber, is circulated via the blower, which is preferably controlled and/or regulated.
