Abstract: An oven having enhanced cooling efficiency. The oven includes a cooking chamber, a door to open or close a front side of the cooking chamber, a cooling fan located above the cooking chamber to suction and blow outside air, a discharge duct to discharge the air, blown by the cooling fan, forward of the door, a plurality of flow-paths defined in the door to allow outside air to be introduced into and moved in the flow-path in association with discharge of the air through the discharge duct, and a suction pipe to connect at least one of the flow-paths and the cooling fan to each other. Suction force of the cooling fan is applied to the flow-paths of the door through the suction pipe as well as the interior of an electric machine room, allowing the air in the flow-path to be discharged to the outside through the suction pipe and the discharge duct. This assures more active air movement in the door and maximizes the cooling effect of the door.

Abstract: Disclosed are a sensor, a cooking apparatus having the sensor, and a control method of the cooking apparatus. The sensor serves to accurately sense a pollution level of the cooking apparatus and to inform of a cleaning time and/or cleaning method based on the pollution level. The pollution level of a cooking compartment may be objectively determined using the sensor that senses the pollution level via a variation of capacitance. Also, it may be possible to guide a cleaning time and/or cleaning method (e.g., manual cleaning, steam cleaning, thermal decomposition cleaning, etc.) based on the pollution level of the cooking compartment, allowing the cooking compartment to be cleaned in the cleaning method at an appropriate cleaning time. In particular, during a thermal decomposition cleaning operation, the pollution level is sensed in real time to enable variable control the cleaning time and automatic control of a cleaning ending time. This may contribute to reduce energy consumption and discharge of CO2.
