Extractor hood

An extractor hood equipped with a fan of which air volume can be changed in response to a temperature of a cooking subject disposed on a cooker, the extractor hood comprising:

• an infrared sensor for detecting an average temperature between the cooking subject temperature at a top face of the cooker and an ambient temperature of the cooking subject;
• a temperature sensor for detecting an ambient temperature of the cooker;
• a signal receiver for receiving a cooker signal supplied from the cooker;
• and
• an air-volume controller for changing the air volume of the fan,
• wherein the air-volume controller calculates the cooking subject temperature based on the average temperature by using the ambient temperature of the cooker as the ambient temperature of the cooking subject, and then determines the air volume of the fan based on the cooking subject temperature and the cooker signal.
