Abstract

Cooking apparatus ( 10 ) includes heating chamber ( 4 ) in which an object to be heated is rested, radiant heater unit ( 38 ) provided inside heating chamber ( 4 ) and operating in the preheating mode and cooking mode, and a control unit controlling radiant heater unit ( 38 ). The control unit is configured to make radiant heater unit ( 38 ) operate in the standby mode, which is a mode after the preheating mode ends and until the cooking mode starts. According to this aspect, the surface temperature of radiant heater unit ( 38 ) is kept at a high level during the standby mode to suppress uneven browning due to variations in the surface temperature of radiant heater unit ( 38 ) when cooking starts.

First claim

The invention claimed is:

1. A cooking apparatus comprising:
a heating chamber in which an object is rested;
a radiant heater unit including a convection heater and a circulation fan that are provided inside the heating chamber, and configured to radiant-heat the object rested in the heating chamber by radiant heat;
a convection device provided behind a back surface wall of the heating chamber, and configured to take in air inside the heating chamber, heat the air, and send out a hot airflow into the heating chamber;
a fan drive unit configured to drive the circulation fan; and
a control unit having a preheating mode and a cooking mode as heating modes, and configured to control the radiant heater unit and the convection device,
wherein:
the control unit is configured to start operating the radiant heater unit and the convection device simultaneously when the preheating mode starts,
the control unit is configured to set a first output power of the radiant heater unit from among a plurality of output power values, a value of the first output power being different in response to a different starting temperature inside the heating chamber when the preheating mode starts,
the control unit is configured to stop the convection device after a predetermined time since the preheating mode started, and
the control unit is configured to continue to make the radiant heater unit operate without turning off the radiant heater unit during a period after the preheating mode ends and until cooking starts.

2. The cooking apparatus according to claim 1 , wherein:
the control unit is configured to change the first output power to a second output power when the cooking mode starts.
