The present invention relates to a method for controlling a steam generating system (10) for a domestic steam cooking oven (40). A steam generator (26) and an inlet valve (16) are controlled by a regulating thermal switch (30) and a limiting thermal switch (32). The regulating thermal switch (30) and the limiting thermal switch (32) respond to a temperature within and/or at the steam generator (26). A threshold value of the limiting thermal switch (32) is higher than a threshold value (Ts) of the regulating thermal switch (30). The steam generator (26) is deactivated and the inlet valve (16) is activated by the regulating thermal switch (30), if the temperature (T) of the steam generator (26) exceeds the threshold value (Ts) of the regulating thermal switch (30).

A method for operating the cooking device, especially a commercial cooking device cooking device with different operating modes, which has a least one heating device, a main cooling fan, at least one electrical component in a first space directly acted upon by the main cooling fan, at least one other electrical component which is to be cooled in a second space not directly acted upon by the main cooling fan, wherein the method has the following method steps: determining and setting limit temperatures which are assigned to the operating modes with cooling being initiated when these are exceeded, determining the activated operating mode, determining whether in the first space a temperature that is dependent on the activated operating mode exceeds the limit temperature assigned to the activated operating mode, and activating the main cooling fan if it is determined that the temperature is above the limit temperature or limit temperatures, wherein part of the aspirated air flow is conducted directly into the second space.

A method of controlling a cooking apparatus, comprising a cleaning process comprising controlling a temperature in a cooking chamber such that the temperature in the cooking chamber is maintained at a preset first temperature for a preset first time, and controlling a temperature in a cooking chamber such that the temperature in the cooking chamber is maintained at a preset second temperature higher than the first temperature for a preset second time. A cooking apparatus comprising, a main body having a cooking chamber formed therein, a convection flow unit comprising a convection heater to heat air in the cooking chamber and a convection fan to circulate the air in the cooking chamber, and a metal foam installed at a periphery of the convection flow unit to collect and decompose cooking gas contained in the air in the cooking chamber.

An oven appliance includes a housing defining a discharge vent, a cooking chamber positioned within the housing, an exhaust duct providing fluid communication between the cooking chamber and the discharge vent, an air handler operably coupled with the exhaust duct for urging a flow of heated air from the cooking chamber, through the exhaust duct, and out of the discharge vent, and a catalytic converter assembly. The catalytic converter assembly includes a catalytic element positioned within the exhaust duct for lowering volatile organic compounds from the flow of heated air and a catalyst heater positioned upstream of the catalytic element for selectively heating the flow of heated air.

A convection oven includes a cooking chamber for cooking a food product, an air circulator that circulates process air in a first direction through the cooking chamber and along a circulation path in a circulation passage. A heat exchanger includes one or more heat transfer ducts longitudinally arranged along the circulation path. One or more heating elements heat a fluid that is circulated in a second direction through the one or more heat transfer ducts which is opposite to the first direction. The process air absorbs heat from the heated fluid as the process air travels along the circulation path back to the cooking chamber. A partition wall may separate first and second parallel portions of the one or more heat transfer ducts. A heat exchanger may preheat fluid entering the one or more heat transfer ducts using heated fluid leaving the heat transfer ducts.
