A rotation sensor 26 is disposed in relation to an output shaft of a motor 25 for driving a door capable of opening and closing an opening of a cooking device body in an opening/closing direction. A microcomputer 20 controls drive of the motor 25 including a rotation direction by receiving an input of a detection signal of the rotation sensor 26,which is a sensor for generating two rotation pulses having different phases (for example, pulse train signals with a 120-degree difference) from the motor. A control device can determine the rotation direction of the motor 25 based on the two rotation pulses therefrom."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Drawer-type cooking device and method for controlling door thereof","description":"A drawer-type cooking device and a method for controlling opening and closing of a door thereof, in which an opening/closing direction and an absolute position of a door by a manual opening/closing op","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8479646","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
