Patent number: 10842310Abstract: The present invention provides a cooking device (1A) which, in a case where food items are cooked consecutively, makes the cooked food items uniform in condition. The cooking device (1A) includes an upper heater (17), a d lower heater (18), a steam supplying section (20), a temperature sensor (27), and a heating control section (31A). The heating control section (31A) controls, based on the temperature measured by the temperature sensor (27), the operations of the upper heater (17) and the lower heater (18) so that the temperature in a cooking room (14) becomes equal to a given temperature. In a case where the time from the start of a cooking process to the end of the cooking process is divided into a preceding time period and a subsequent time period, the heating control section (31A) suspends the operations of the upper heater (17) and the lower heater (18) while the temperature in the cooking room (14) is higher than a given preceding target temperature (T1) during the preceding time period.Type: GrantFiled: January 24, 2017Date of Patent: November 24, 2020Assignee: SHARP KABUSHIKI KAISHAInventors: Kazuya Kitatani, Masayuki Iwamoto, Manami Kobayashi, Rika Nozawa, Keisuke Morishita, Minoru Tanaka
