Cooking device

摘要

A cooking device has an exhaust duct (19) configured and arranged to mix together exhaust air discharged from an opening (61a) at a tip of a nozzle part (61) and part of cooling air discharged from a cooling fan and guide the mixed exhaust air to discharge it outside of a casing, and an exhaust duct temperature sensor (70) placed within the exhaust duct (19) to detect a temperature of an atmosphere inside the exhaust duct at a portion upper than the opening (61a) of the nozzle (61). A fan abnormal-stop detection part detects an abnormal stop of the fan when an increment per unit time of an atmosphere temperature inside the exhaust duct (19) detected by the temperature sensor (70) during cooking becomes equal to or higher than a first threshold value.

主权项

1. A cooking device comprising:
a casing; a heating chamber placed in the casing; a fan placed in the casing; an exhaust path having one end connected to the heating chamber; an exhaust duct configured and arranged to mix together exhaust air discharged from another end of the exhaust path and at least part of air from the fan and guide the mixed exhaust air to outside of the casing such that the mixed exhaust air is discharged outside; a temperature sensor configured and arranged to detect an atmosphere temperature inside the exhaust duct; and a fan abnormal-stop detection part configured and arranged to detect an abnormal stop of the fan when an increment per unit time of the atmosphere temperature inside the exhaust duct detected by the temperature sensor during cooking becomes equal to or higher than a first threshold value or when the atmosphere temperature inside the exhaust duct detected by the temperature sensor during cooking becomes equal to or higher than a fan abnormal-stop decision temperature, wherein the fan abnormal-stop detection part is inhibited from detecting the abnormal stop of the fan until after a first specified time has passed after a start of cooking.
