The present invention relates to a steam system for a steam cooking appliance. The steam system includes a steam generator and a precipitator. The precipitator is arranged above the steam generator. The steam generator comprises two vertical heating pipe sections. Upper ends of the heating pipe sections are connected to a bottom side of the precipitator. Lower ends of the heating pipe sections are connected by a transverse pipe section. At least the heating pipe sections are at least partially enclosed by one of more heating elements. An inlet pipe is connected to the transverse pipe section at one end and connected or connectable to a water reservoir or water pump at another end. A return pipe is interconnected between the bottom side of the precipitator and the transverse pipe section. Further, the present invention relates to a corresponding steam cooking appliance.

A steam oven having a housing, a cooking chamber located within the housing, a water tank receptacle connected to the housing, the water tank receptacle comprising: a reservoir, an inlet fitting positioned above the reservoir, a false bottom positioned above the reservoir, and a reservoir outlet extending through a bottom of the reservoir. A water tank is selectively positionable on the water tank receptacle above the false bottom, the water tank having an outlet fitting configured to fluidily connect to the inlet fitting upon positioning the water tank on the water tank receptacle.

A steam generator and a cooking apparatus including a steam generator are provided. The steam generator may include a heater, an inflow tube, a steam generation tube, and a discharge tube and an adaptor unit connected to the steam generator may be provided. The inflow tube and the discharge tube and the discharge tube may be connected at a predetermined angle to the adaptor unit. Thus, the steam generation tube connecting the inflow tube to the discharge tube may also be inclined.

A modular oven includes a cabinet receiving separate modules with distinct cooking operations. Modules of the modular oven may provide any combination of convection cooking, steam cooking, impingement cooking, and high speed cooking. Therefore, the modules may be mixed and matched to suit the desired cooking operations. In some embodiments, improved steam cooking at lower cooking temperatures is provided by directing spraying water onto an independent heat source, controlled separately from the cavity heating element, within each cooking zone. By operating a separate heating element specifically for steam generation, there can be more accurate heat control of the cooking zones without overheating the cooking zones when steam is needed but when lower cooking temperatures (e.g., 211 degrees Fahrenheit and below) are desired.

A cooking appliance, in particular a commercial cooking appliance, comprising a housing in which a cooking space is arranged and which is provided with a housing outlet, a condenser connected with the cooking space, a cooling water supply device and an appliance outlet, wherein the condenser has a multi-chamber system and the cooling water supply device comprises at least one supply line leading into the chamber provided with the appliance outlet.

A steam generator and a cooking apparatus having a steam generator are provided. The steam generator may include a steam generation tube; an inflow tube configured to provide a passage so that water is introduced into the steam generation tube; at least one heater disposed on an outer surface of the steam generation tube to heat the water and generate steam; a discharge tube disposed above the steam generation tube to provide a passage so that the steam is discharged; and an adaptor unit configured to branch discharge water and the steam discharged from the discharge tube. The discharge tube may have an inner diameter that gradually increases in an upward direction.

An oven having water injection system comprising an oven including a compartment enclosed on all sides, a water injector, and a first water valve coupled to the water injector, wherein the water valve includes proportional control.

A process and apparatus for heating, cooling or heating and cooling multiple chambers of a food preparation device utilizing heated and/or cooled nebulized water particles and heated and/or cooled compressed air. The steps of heating include heating water contained in reservoir located outside of the cooking chambers, heating compressed air, conveying the heated water and the heated compressed air to at least one nebulizer, nebulizing the heated water into heated water particles and introducing the heated water particles into the cooking chamber via the heated compressed air. The steps of cooling include cooling water contained in an additional reservoir located outside of the cooking chambers, cooling compressed air, conveying the cooled water and the cooled compressed air to at least one nebulizer, nebulizing the cooled water into cooled water particles and introducing the cooled water particles into the cooking chamber via the cooled compressed air.

A steam cooker having a main body, a cavity provided inside the main body, a steam generator provided to generate steam, a supply pipe connecting the steam generator to the cavity to supply steam into the cavity, a discharge pipe arranged to discharge the steam inside the cavity to the outside of the cavity, a discharge nozzle coupled to an end of the discharge pipe, and a cooling fan provided between the cavity and the main body to cool the cavity, and wherein the discharge nozzle is disposed adjacent to the bottom of the cooling fan such that steam discharged through the discharge nozzle is guided downward between the cavity and the main body by the cooling fan. The steam cooker can prevent the condensation water from falling down on the lower part of the main body.

In a method for operating a household cooking appliance with a cooking chamber, a humidity value is monitored in the cooking chamber, and a sign is output when the humidity value reaches or falls below a predetermined threshold value.
