A heating cooking apparatus (1) includes a heating cooking chamber (10), heat supply units (41), (42), and (44), a housing (14), a fan (50), a pull-out body (13), a slide rail (30), and guide portions (52a) and (52c). The heat supply units (41), (42), and (44) supply heat to an interior of the heating cooking chamber (10). The housing (14) accommodates the heating cooking chamber (10). The fan (50) is disposed in a space (R) formed between an outer surface of the heating cooking chamber (10) and an inner surface of the housing (14). The fan (50) generates an air flow (BF). The pull-out body (13) can be freely pulled out relative to the heating cooking chamber (10). The slide rail (30) is attached to the outer surface of the heating cooking chamber (10). The slide rail (30) slidably supports the pull-out body (13). The guide portions (52a) and (52c) guide the air flow (BF) so that the air flow (BF) flows along the slide rail (30).

The present invention relates to a drying apparatus capable of regenerating an adsorbent used for drying using microwaves. The drying apparatus of the present invention is formed to include a microwave irradiation means configured to irradiate microwaves to the adsorbent in a plurality of reaction towers in which the adsorbent adsorbing moisture or carbon dioxide is embedded, and when regenerating the adsorbent, directly heats the adsorbent using microwaves, thereby shortening a heating time and securing a sufficient cooling time, resulting in the effect of reducing the amount of dry air consumed for cooling and further increasing the drying efficiency.

An oven may include a cooking chamber configured to receive a food product, a radio frequency (RF) heating system configured to provide RF energy into the cooking chamber using solid state electronic components to heat the food product, and a context awareness engine. The context awareness engine may include processing circuitry configured to receive RF signature data (including measurements of at least forward power and reflected power) associated with provision of RF energy into the cooking chamber, and to correlate an RF signature with a phenomenon observed with respect to the food product to define a signature profile for the phenomenon observed.

A cooking apparatus has a cooking chamber, a microwave unit to radiate microwaves to the cooking chamber, a convection unit to supply hot air to the cooking chamber, a grill unit to supply radiant heat to the cooking chamber, an input unit to receive a cooking command and a control unit to perform a cooking corresponding to the received cooking command by performing one of a first heating stage and a second heating stage, and after performing the one of the first heating stage and the second heating stage, performing the other one of the first heating stage and the second heating stage. In the first heating stage, the control unit operates the microwave unit and at least one of the convection unit and the grill unit, and in the second heating stage, the control unit operates the grill unit and the convection unit while not operating the microwave unit.

A method of operating cooking appliance includes activating a motor to rotate a turntable within a cooking cavity defined in a casing of the cooking appliance. The methods also includes activating a cooking lamp in response to the turntable reaching a first angular position after activating the motor to rotate the turntable and deactivating the cooking lamp in response to the turntable reaching a second angular position after the first angular position.

An oven appliance includes a chamber, a fan assembly operable to cause air to flow in the chamber, and a first heating element adjacent to a bottom wall of the oven appliance. The oven appliance further includes a removable heating element cover configured for defining a duct in fluid communication with the fan assembly and the first heating element for directing airflow in the chamber to the fan assembly and across the first heating element to heat a food item. The oven appliance also includes a sensing device for detecting a presence of the heating element cover and a controller having a processor configured to receive an indication from the sensing device confirming whether the heating element cover is engaged with the sensing device and control operation of the oven appliance based on the indication.
