A stepless temperature control method for an air fryer includes the steps of detecting and analyzing an air temperature in an air frying chamber of the air fryer in a real-time manner to obtain a temperature change in the air frying chamber, modulating a parameter of a stepless control signal according to a preset target temperature and the temperature change, and, in response to the modulated stepless control signal, adjusting a heating power of the air heater of the air fryer in a stepless manner, so as to maintain the air temperature in the air frying chamber between an upper limit and a lower limit of the preset target temperature.

The electric cooking appliance comprises a cooking vat; a lid (6) comprising a lid body (7) and an inner lid (8) comprising a fixed closure portion (12) attached to the lid body (7) and a movable closure portion (13) that can be moved relative to the fixed closure portion (12) between a raised configuration in which the fixed closure portion (12) and the movable closure portion (13) close the cooking vat, and a lowered configuration in which the fixed closure portion (12) and the movable closure portion (13) define an air vent passage (14) to the outside of the cooking volume (5) and an air intake passage (15) to the inside of the cooking volume (5); a fan (24) configured to generate an airflow; and a heating device (25) configured to heat the airflow generated by the fan (24) and located near the air intake passage (25) when the lid (6) occupies the closed position.

A grill system is disclosed and may include a grate comprising a plurality of grill members. The grate may include a stationary region and a chute aperture. The grill system may further include a chute comprising a chute top portion and a chute bottom portion. The chute may engage the grate by traversing through the chute aperture. The perimeter of the chute aperture may be reinforced by a secondary member.

A bean roasting system includes a roasting subsystem and an air handling subsystem. The roasting subsystem includes a housing, an agitator actuator, an agitator, a bearing and a door. The housing has an inner surface defining an inner chamber for holding a batch of beans during a thermal roasting process. The agitator is coupled to the agitator actuator and includes a central shaft and a blade set mounted to the central shaft. The bearing supports the central shaft and is configured to prevent the blade set from contacting the inner surface of the housing. The door has a transparent window to allow viewing of the thermal roasting process. The air handling system is coupled to the roasting subsystem, includes a blower and heater, and is configured to circulate heated air through the roasting subsystem during the thermal roasting process.

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.
