Abstract

An extractor hood that alters the volume of air from a fan in accordance with the temperature of the food being cooked in a cooker, and that is provided with: an infrared sensor for detecting an average temperature from the temperature of the food being cooked and the ambient temperature of the food being cooked; a temperature sensor for detecting the ambient temperature of the cooker; a signal reception unit; and an air volume control unit. In the air volume control unit, the temperature of the food being cooked is calculated from the average temperature using the ambient temperature of the cooker as the ambient temperature of the food being cooked, and the volume of air from the fan is determined using a cooker signal and the temperature of the food being cooked.

Description

technical field [0001] The invention relates to a range hood. Background technique [0002] A conventional range hood that changes the air volume of a blower according to the temperature of the cooking item includes an exhaust fan motor, a thermoelectromotive force type temperature sensor, and a control unit. Here, the exhaust fan motor exhausts oily fumes and odors generated during cooking to the outside. A thermoelectromotive force type temperature sensor detects far infrared rays around heating and cooking equipment. The control unit converts the result detected by the thermoelectromotive force type temperature sensor into a temperature. Then, the range hood determines the use state of the heating and cooking appliance based on the temperature converted by the control unit, and drives or stops the exhaust fan motor (for example, refer to Patent Document 1). [0003] In the cooker hood of Patent Document 1, the previous detection temperature detected by the thermoelectr...
