AI Technical Summary

Technical Problem

Existing range hoods with cooling functions have poor airflow performance, which can easily interfere with the absorption of cooking fumes. Furthermore, they cannot intelligently adjust the airflow direction, resulting in a poor cooking experience for users.

Method used

By setting up a smoke extraction module and a cooling module in the fume treatment device, the air outlet is vented to the left and right by rotating the air guide plate around the first axis. The number and position of users are determined by the number of people and position sensors, and the rotation angle of the air guide plate is adjusted to meet the cooling needs, providing automated orientation control.

Benefits of technology

It effectively collects the cooling needs of kitchen users, provides a comfortable cooling environment, improves the user's cooking experience, and avoids air supply interfering with the absorption of oil fumes.

Abstract

This invention discloses an oil fume treatment device and its control method. The cooling housing of the oil fume treatment device is provided with an air outlet extending vertically; a guide vane is provided at the air outlet, and the guide vane is rotatable around a first axis extending vertically. The control method includes: determining the number of users and their relative positions in the space where the oil fume treatment device is located; determining the air supply mode of the cooling module; and adjusting the rotation angle of the guide vane according to the number of users, their relative positions, and the air supply mode of the cooling module. This invention solves the problems of poor air supply effect, easy interference with oil fume absorption, and inability to intelligently adjust the direction of airflow in existing range hoods with cooling functions. It can adapt to the user's cooling needs, providing automated directional control in the left and right directions, achieving a comfortable cooling environment during cooking, and improving the user's cooking experience.
