A method for cleaning a cavity of an oven having a steam generation device, comprising the following steps: (i) a step of mild detergent cleaning, comprising (i.1) a step of applying mild detergent to the oven cavity at a predetermined cavity starting temperature (T.sub.0), and subsequently (i.2) a step of incubating the oven cavity for a predetermined incubation period of time (t.sub.inc1) at a temperature T.sub.act, (i.3) a step of applying steam generated by the steam generation device to the oven cavity for a steam period of time (t.sub.steam1) until the oven cavity reaches a temperature T.sub.1, and subsequently incubating the oven cavity for an incubation period of time (t.sub.inc2) until the oven cavity reaches a temperature T.sub.2, and (i.4) a step of removing water and dirt from the oven cavity; and (ii) a step of steam cleaning, comprising (ii.1) a step of applying steam generated by the steam generation device to the oven cavity for a steam period of time (t.sub.steam2) until the oven cavity reaches a temperature T.sub.3, and subsequently incubating the oven cavity for an incubation period of time (t.sub.inc3) until the oven cavity reaches a temperature T.sub.4, and (ii.2) a step of removing water and dirt from the oven cavity.

A method for identifying a degree of soiling of an interior of a cooking appliance, in particular of the cooking chamber, during at least one of a cleaning operation and a cooking operation and a method for cleaning such a cooking appliance interior include determining at least one parameter of a liquid and a degree of soiling.

A grilling machine is described, which comprises a base body, a plate, arranged on the base body and defining a cooking surface whereon foods to be cooked are laid, and heating means operationally associated with the plate for heating the cooking surface. There is also a circuit, associated with the plate, for treating the fumes produced during the food cooking process. The fumes treatment circuit comprises: a hood arranged above the plate, which comprises at least one suction mouth, a filtering unit fluidically connected to the hood, and at least one recirculation outlet fluidically connected downstream of the filtering unit and located near the plate. In this manner, the cooking fumes sucked in through the suction mouth of the hood are treated by the filtering unit in order to obtain a purified flow with a given percentage of humidity. The purified flow is then recirculated towards the cooking surface through the recirculation outlet in order to exert a humidifying action on the foods.

The present invention relates to a method for cleaning a commercial cooking device (100, 100), in which a container (B, B) with a solid cleaning agent (1R), in particular a firm gel, is accommodated in a connection unit (101, 102) of the commercial cooking device (100, 100), and in which the solid cleaning agent (1R) is liquefied in the cleaning process in the container (B, B) by means of heat and/or a solvent, preferably water and/or steam, in order to generate a liquefied cleaning agent. In addition, the invention relates to the use of a container (B, B) with a solid cleaning agent (1R) for cleaning a commercial cooking device (100, 100). Finally, the present invention relates to a corresponding container (B, B) with a solid cleaning agent (1R) for cleaning commercial cooking devices.

A cooking apparatus has a cooking chamber and a heating chamber adjacent the cooking chamber used for heating air laden with steam. A fan is mounted in the heating chamber and it circulates the air and steam between the cooking chamber and the heating chamber, through a vent arrangement. An additional drainage outlet is provided at a base of the heating chamber and for example leads to the cooking chamber. This is used to allow liquid such as condensate to flow from the heating chamber for example to the cooking chamber, for example to enable easy removal of residue formed during a cleaning process.
