摘要： The present invention is related to a cooking oven (1) for foodstuffs comprising:
- a cooking chamber (2), wherein foodstuffs can be placed for being cooked, having a bottom wall (3) provided with a first cooking chamber outlet (4) positioned in such a way to receive grease collected in the bottom wall (3);
- a grease conduit (6) configured for draining grease from the cooking chamber (2); wherein the first cooking chamber outlet (4) is fluidly connected to the grease conduit (6), wherein the cooking oven further comprises:
- a heating device (8) configured for heating the internal of the cooking chamber (2),
- a vapour outlet duct (9) configured for discharging vapour from the cooking chamber (2), wherein the bottom wall (3) of the cooking chamber (2) is provided with a second cooking chamber outlet (10), distinct from the first cooking chamber outlet (4) and fluidly connected to the vapour outlet duct (9).

摘要： The present invention is related to a cooking oven (1) comprising:
- a cooking chamber (2) wherein foodstuffs can be placed for being cooked, comprising an upper wall (23); - a heating device (8) for heating the internal of the cooking chamber (2); - a suction wall (18) separating the cooking chamber (2) from a heating chamber (19) containing, at least partially, the heating device (8); - a centrifugal fan (20), positioned in the heating chamber (19) and configured for circulating an airflow through the cooking chamber (2) and the heating chamber (19); wherein the suction wall comprises a suction mouth (18a) facing a central region of the centrifugal fan (20), wherein the cooking oven (1) comprises: - a cleaning system (70) comprising a washing/rinsing liquid introduction system (16) configured for taking washing/rinsing liquid within the cooking chamber (2) and provided with an outlet (16c) positioned in the upper wall (23) of the cooking chamber (2), wherein the cooking oven (1) comprises:
- a diverting element (24) configured for receiving a liquid (900) exiting the outlet (16c) of the washing/rinsing liquid introduction system (16) and for spreading it on the suction wall (18) so as to form a liquid film (910) on it, which is taken by gravity into the suction mouth (18a).
The invention also relates to a method for operating such an oven, comprising the following steps: - taking a washing/rinsing liquid within the cooking chamber (2) of the cooking oven (1) via the outlet (16c) of the washing/rinsing liquid introduction system (16) of the cleaning system (70) of the cooking oven (1); - receiving, by the diverting element (24), the washing/rinsing liquid exiting the outlet (16c); - spreading, by the diverting element (24), the received washing/rinsing liquid on the suction wall (18) so as to form a liquid film (910) on it, which is taken by gravity into the suction mouth (18a); - activating the centrifugal fan (20) so as to suck the washing/rinsing liquid in form of the liquid film (910), and to blow radially the washing/rinsing liquid in form of droplets together with the generated airflow (950).

摘要： The present invention is related to a method for the automatic or semiautomatic cleaning of a cooking oven (1), wherein the cooking oven (1) comprises:
- a cooking chamber (2), wherein foodstuffs can be placed for being cooked, having a bottom wall (3),
- a heating device (8) configured for heating the internal of the cooking chamber (2),
- a cleaning system (70) comprising a circulation system (7) configured for pumping liquid out of the cooking chamber (2) via one or more cooking chamber outlets (4, 10) and for pumping such liquid, or a part thereof, again in the cooking chamber (2), wherein the method comprises the following phases:
a) a washing phase (1000), comprising:
- loading and collecting into the bottom wall (3) of the cooking chamber (2) a washing liquid and/or water and detergent so as to form a washing liquid therein, until the washing liquid submerges the one or more cooking chamber outlets (4, 10) and reaches a prefixed level or amount within the cooking chamber (2),
- circulating the washing liquid into and out from the cooking chamber (3) by the circulation system (7),
- draining the washing liquid from the cooking chamber (3);

b) one or more rinsing phases (2000, 2001), performed after the washing phase (1000), and comprising:
- loading and collecting rinse water into the bottom wall (3) of the cooking chamber (2) until the rinse water submerges the one or more cooking chamber outlets (4, 10) and reaches a prefixed level or amount within the cooking chamber (2),
- circulating the rinsing water into and out from the cooking chamber (3) by the circulation system (7),
- draining the rinsing water from the cooking chamber (3).
