Abstract

The invention provides a range hood, which controls the air volume of a fan and the rotation speed of a filter to an optimal state together. A pollution state detection sensor (310) detects the pollution state of the air from the cooking appliance. A cooking state detection sensor (320) detects the cooking state of the cooker. A fan (116) exhausts the air from the upper part of the cooker. A filter (118) removes oil from the soot contained in the air in the upper part of the cooker. A control unit (130) controls the air volume of the fan (116) by using the pollution state of the air detected by the pollution state detection sensor (310). A detection sensor (310) uses the cooking state detected by the cooking state detection sensor (320) to control the rotation speed of the filter (118).

Description

technical field [0001] The invention relates to range hoods. Background technique [0002] In the past, the following range hoods are known: a temperature sensor provided on the range hood is used to detect the top surface temperature of the cooker, and based on the detected top surface temperature, the air volume of the fan and the rotation speed of the filter are simultaneously controlled (patent document 1). [0003] Patent Document 1: Specification of Japanese Patent No. 5684106 [0004] The invention disclosed in Patent Document 1 determines whether or not cooking is cooking that generates a large amount of oily smoke based on the detected top surface temperature, and simultaneously controls the air volume of the fan and the rotational speed of the filter. However, both the air volume of the fan and the number of rotations of the filter may not necessarily be controlled in an optimal state. [0005] The filter rotates to increase the collection rate of oil contained ...
