Cooking oven

Abstract

A Cooking oven () comprising a) at least one cooking cavity () and b) at least one steam generation system () for introducing steam into the cooking cavity () during a steam operating mode, in particular steam cooking mode or steam cleaning mode, c) wherein the steam generation system () comprises c1) at least one steam generator (), c2) at least one fluid supply (), the fluid preferably being water with impurities, in particular calcium, and optionally additives and c3) at least one valve (), d) wherein the valve () is interconnected between the fluid supply () and the steam generator () in order to control the flow of fluid from the fluid supply () to the steam generator () during the steam operating mode, e) wherein the valve () comprises at least one inlet () for the fluid being in fluid connection with the fluid supply () f) wherein the valve is in fluid connection with the steam generator () by means of at least one connecting line (), g) wherein the valve () is provided with at least one closing device () for closing and opening the inlet () of the valve at least partially during the steam operating mode in order to keep the fluid level within the valve at an operating level within an operating level range during the steam operating mode, h) the cooking oven further comprising one or more of the following features: h1) the valve () and the steam generator () and the connecting line () are arranged in such a way that the level of the fluid within the steam generator () and within the valve () is kept the same during the steam operating mode and/or wherein the valve () and the steam generator () and the connecting line () are arranged according to the principle of communicating vessels, h2) the operating level (N) or the operating level range during the steam operating mode is, in the direction of gravity, higher than or at the same level as the inlet () of the valve ().
