AI Technical Summary
The air outlet component of the cooling range hood has an uneven airflow problem, which makes it easy for hot air to recirculate and for condensation to occur due to alternating hot and cold air in areas with low airflow, thus affecting the user experience.
The air outlet assembly design includes a first guide plate and a second guide plate. By coordinating the guide plates, the airflow is diverted, increasing the airflow at the outlet and preventing airflow from being blown out from areas with low wind speed, thus ensuring more uniform airflow.
It achieves uniform airflow, avoids hot air recirculation and condensation, improves user experience, reduces energy consumption, and enhances cooling performance.
