A method of operating cooking appliance includes receiving, by a controller of the cooking appliance, an input indicating a time of a cooking operation. The method also includes activating a motor to rotate a turntable within a cooking cavity defined in a casing of the cooking appliance throughout the time of the cooking operation and activating a microwave module to deliver microwave energy into the cooking cavity during at least a portion of the rotation of the turntable. The method further includes varying at least one of a speed of the rotation of the turntable and a duty cycle of the microwave module during the cooking operation.

Multiple temperature-control process for stators (7) and rotors of electric motors and components consisting of materials with different magnetic properties by means of a triplex furnace (1) for the quick, efficient, and uniform heating-up of preferably tubular components such as stators (7), wherein the magnetic parts of a component are primarily heated up by means of induction and at the same time non-magnetic parts of the same component are primarily heated up by means of infrared radiation, and at the same time and subsequently secondary heating takes place by means of convection, in particular by passive heating elements (10), which serves for finely adjusting the target temperature and for maintaining it.

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 convection oven is provided. An oven cavity is defined by at least by a top wall, a left side wall, a right side wall, and a door configured selectively open and close the oven cavity. An air channel defines a convection airflow out of and back into the oven cavity, the top wall defining an air inlet to allow the convection airflow to enter the air channel from the oven cavity, the walls further defining a plurality of outlets to allow the convection airflow to exit the air channel and reenter the oven cavity. Each of the plurality of outlets houses a corresponding one of a plurality of heating tubes, each corresponding heating tube being mounted along the convection airflow exiting the air channel.

A pull-out heating cooking apparatus (1) includes a heating chamber (10), a drawer body (11), a fan (21), a microwave supply unit (14), an air sending unit (15), and a main body outer case (40). The heating chamber (10) includes a panel (100) provided with a first through hole part (100B) and a second through hole part (100C) are formed. In the heating chamber (10), a first space (S1) and a second space (S2) are formed between an outer surface of the heating chamber (10) and an inner surface of the main body outer case (40). The fan (21) takes in air from the first through hole part (100B) to the first space (S1), and circulates the air to the fan (21) via the first space (S1). The fan (21) blows out the air to the second space (S2) and circulates the air to the second through hole part (100C) via the second space (S2).
