AI Technical Summary
Technical Problem
Traditional range hoods have poor sound insulation in their air intake grilles, which makes it easy for noise to spread into the kitchen environment, affecting the user experience.
Method used
A multi-layered, spaced-apart air intake panel structure is designed. The air intake panel has through holes, and ribs are set between adjacent holes. Sound-absorbing material is filled in the interlayer to form a multi-layered grid structure, which reduces noise transmission by reflecting and scattering sound waves multiple times.
Benefits of technology
Through the reflection and scattering of the multi-layered grille structure, the noise transmission during the operation of the range hood is significantly reduced, improving the sound insulation effect and user experience.

Abstract
This utility model provides an air inlet grille and a range hood including the same. The air inlet grille is installed at the air inlet of the range hood and includes several layers of spaced-apart air inlet plates. Multiple air inlet holes penetrating all the air inlet plates are formed on the air inlet grille. This air inlet grille and the range hood including the same form a multi-layer grille structure through the layers of spaced-apart air inlet plates and the air inlet holes penetrating all the air inlet plates. This allows the sound waves generated by the range hood to be reflected and scattered multiple times by the multi-layer grille when passing through the air inlet holes, gradually weakening the sound wave energy, reducing noise propagation, thereby improving sound insulation and enhancing the user experience.
