AI Technical Summary
Technical Problem
Range hoods are primarily designed for exhausting gases generated during cooking and lack the capability to detect and exhaust gases in non-cooking spaces.
Method used
A range hood with a secondary airflow path and detection unit that can detect air quality in non-cooking spaces by using a CO2 sensor positioned in a secondary flow path separate from the main airflow path, allowing detection of gases outside the cooking area.
Benefits of technology
Enables the detection and exhaust of gases generated in non-cooking spaces, improving air quality in areas like living rooms by detecting CO2 levels and other substances.

Abstract
To suitably detect gas generated in a non-cooking space except at the time of cooking.SOLUTION: A range hood 100 comprises: a hood part 91 generating an airflow by an operation of a fan 94, and having a suction opening 95 provided to suck air on a cooker; and a body part 92 having a discharge port 96 provided to discharge the sucked air. The range hood comprises a main flow path reaching to the fan from the suction opening in an airflow path, an auxiliary flow path reaching to the fan from a suction hole 11a formed on a face of the hood part different from the suction opening, and a detection part 10 arranged in the auxiliary flow path on an upper stream side than a confluence point of the main flow path and the auxiliary flow path, and detecting an air quality of air in the auxiliary flow path. The air flows into the main and auxiliary flow paths by an operation of the fan, and the detection part detects the air quality in the auxiliary flow path when the airflow is generated in the auxiliary flow path by the operation of the fan.SELECTED DRAWING: Figure 8
