AI Technical Summary
Technical Problem
The existing air conditioner pass-through style grille cannot effectively block or reduce the noise generated during the fan operation.
Method used
A vent style grid for air conditioning is designed, including a first ventilation zone, whose height matches the diameter of the fan, the first grid in the first ventilation zone is arranged inclined, and the inclination angle gradually decreases from the top end to the bottom end to cover the air inlet side of the fan and effectively block the noise.
Benefits of technology
By setting the multiple first grids at different inclination angles, peak noise can be effectively blocked and discretized, achieving the purpose of noise reduction and enhancing the user's experience.

Abstract
The invention relates to the technical field of air conditioners, and discloses a ventilation grille for an air conditioner, the ventilation grille comprises a first ventilation area, the first ventilation area is arranged corresponding to a fan of the air conditioner, and the height of the first ventilation area is matched with the diameter of the fan; wherein the first ventilation area comprises n first grids, the n first grids are all obliquely arranged, and the inclination angles of part of the first grids are the same. The first ventilation area of the ventilation grille corresponds to a fan of the air conditioner, and the height of the first ventilation area is matched with the diameter of the fan, so that the first ventilation area at least covers the air inlet side of the fan of the air conditioner, namely, the area where noise is formed in the fan is covered, and therefore when noise generated by rotation of fan blades is transmitted to the ventilation grille, the noise is reduced. The multiple first grids are arranged at different inclination angles, noise can be shielded, peak noise can be effectively discretized, the purpose of noise reduction is achieved, and the use experience of a user is improved. The invention further discloses the air conditioner.
