Abstract
An extractor hood changes an air volume of a fan in response to a temperature of a cooking subject on a cooker. The hood includes an infrared sensor that detects an average temperature between the cooking subject temperature and an ambient temperature of the cooking subject, a temperature sensor that detects an ambient temperature of the cooker, a signal receiver, and an air-volume controller. 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 a fan based on the cooking subject temperature and a cooker signal.
