Abstract: A method of estimating fluid in a steam generation system includes periodically determining steam flow rates and drainage flow rates to accurately estimate fluid levels. The method includes determining a first steam flow rate of a steam generator. Before a present steam cycle, determine a starting quantity of liquid in one or more liquid reservoirs. During a present steam cycle, determine a quantity of liquid remaining in the one or more liquid reservoirs by determining a time the steam generator injected steam and multiplying the time by the first steam flow rate. Based on the first steam flow rate, determine a time remaining before the quantity of liquid remaining in the one or more liquid reservoirs is below a threshold and the one or more liquid reservoirs needs to be refilled. With the drain flow rate, the steam generation system can be emptied with minimized dry cycle duration.

Abstract: A separator circuit for a steam generation system. The separator circuit comprises a steamer connection tube and a liquid bin tube that extends vertically between a steam outlet for providing steam to a cavity of a cooking appliance and a recirculation tube for routing condensation back into the provided steam generation system. A slide tube is sloped downwardly from the steamer connection tube to the liquid bin tube for gravitationally accelerating condensation from the steamer connection tube through the liquid bin tube and into the recirculation tube. 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.

Abstract: A steam generating system for an appliance includes a first tank positioned at a first vertical position and having an upper water outlet and a lower water outlet. A second tank is positioned at a second vertical position that is lower than the first vertical position of the first tank. A first and second interconnecting members respectively connect the upper and lower water outlets of the first tank to the second tank. Together, the first and second interconnecting members fluidically connect the first and second tanks. A valve assembly is positioned along the second interconnecting member to selectively provide access to the second tank from the first tank. Inlet and outlet pumps are respectively coupled to the first and second tanks to supply and discharge water from the steam generating system. The appliance further includes a retractable hose for connecting the steam generating system to a water source.

Abstract: A steam generating system for an oven includes an upper tank having an upper water outlet and a lower water outlet. A lower tank is positioned at a vertical position that is lower than a vertical position of the upper tank. A first hose is coupled to the upper water outlet of the upper tank and further coupled to the lower tank. A second hose is coupled to the lower water outlet of the upper tank and further coupled to the lower tank. A valve assembly is positioned along the second hose and operable between open and closed conditions. An inlet pump is coupled to the upper tank and an outlet pump is coupled to the lower tank to provide and discharge water from the system. A method of filling and emptying the steam generating system and generating steam is also provided.
