The present disclosure generally relates to a steam generation system, and, more specifically, to a steam generation system with a separator circuit for separating steam and condensation.
BACKGROUNDCooking appliances, particularly stoves, ovens, microwaves, steamers, and the like, are provided with steam generator assemblies. Cooking with steam, or at least partially with steam, is generally regarded as a healthier and, oftentimes, faster alternative than many other cooking means. As a result, various steam generator assemblies have become a popular addition to cooking appliances. These steam generator assemblies typically include a liquid circuit that includes a water reservoir, a heating element, and a steam outlet. In operation, water from the water reservoir is routed into the heating element whereat it at least partially turns to steam. The steam is then released through the steam outlet and into a cooking cavity to heat and cook foodstuff within the cooking cavity.
Some steam generator assemblies also provide recirculation routes in the liquid circuit, such that heated water that condenses from steam prior to exiting the steam outlet can be recirculated. Inefficiencies arise at the point steam and liquid are mixed prior to the steam being routed into the cavity and the water being recirculated. More particularly, the mixture of liquid and steam accelerates the condensation of the steam. In addition, condensation can exit the steam outlet causing undesirable effects on the foodstuff and cooking appliance.
Accordingly, the present disclosure relates to a steam generation system including a separator circuit that separates the steam and the heated liquid and recirculates the heated liquid in a manner to maximize steam generation and minimize a volume of heated liquid exiting the steam outlet.

A vortex section is located between the slide tube and the liquid bin tube and includes a choke wall. The choke wall extends from a first end decreasing a cross-sectional flow path of the vortex section to a second end in a direction of the liquid bin tube.
According to another aspect of the present disclosure, a separator circuit for a steam generation system is provided. The separator circuit comprises a liquid bin tube and a vortex section connected to the liquid bin tube that includes a choke wall.

It should be appreciated that the first and second embodiments of the steam generation system 10A, 10B may be substantially vertical with respect to the cooking appliance. As such, the steam entering the cooking cavity of a cooking appliance as indicated by reference numeral 28 may be routed substantially upward whereas the heated liquid routed back into the steam generation system 10B as indicated by reference numeral 30 is substantially downward. Accordingly, both the steam output and the heated liquid recirculation is assisted by gravity.
A vortex section 56 is located between the slide tube 46 and the liquid bin tube 48. As best illustrated in
The components of the separator circuit 26 may be integral or non-integral. For example, in some embodiments, the steamer connection tube 44 and the slide tube 46 may be a first integral part.
