AI Technical Summary

Technical Problem

The existing control methods for concealed range hoods have problems such as inconvenient operation, reliance on sensors which are prone to errors, cumbersome wake-up from concealed state, and simple control logic. In particular, they are not adaptable to the operating intentions of users at different distances, resulting in a high false trigger rate and poor interactive experience.

Method used

By recognizing the user's posture information and the distance between the user and the range hood, the system determines the control attribute information, generates corresponding control signals, and realizes non-contact full-process control of the range hood, including mode switching and air volume adjustment at different distances, and adaptive adjustment based on the user's height.

Benefits of technology

It improves the reliability and convenience of range hood control, reduces the false trigger rate, realizes full-process non-contact operation and personalized interactive experience, adapts to the operating intentions of users at different distances, and enhances the user experience.

Abstract

The present application relates to the technical field of intelligent kitchen electrical appliances, and particularly relates to a control method and device of a range hood and an intelligent kitchen electrical appliance. The method comprises the following steps: determining posture information of a user and a distance between the user and the range hood; determining control attribute information based on the distance between the user and the range hood; the control attribute information comprises a control type currently executable by the range hood and a trigger threshold; generating a control signal based on the posture information of the user and the control attribute information; and controlling the range hood to work based on the control signal. In this way, the posture of the user and the distance between the user and the range hood are combined to improve the reliability and convenience of the control of the range hood, and the user experience is improved.
