Air outlet grid used for air purifier and air purifier

Abstract

The invention discloses an air outlet grid used for an air purifier and the air purifier and relates to the technical field of air purifying equipment. The air outlet grid used for the air purifier and the air purifier are invented for solving the problems that an air purifier in the prior art is large in air outlet amount loss and high in noise. The air outlet grid used for the air purifier comprises an inner ring grid body and an outer ring grid body. The inner ring grid body comprises multiple inner ring ribs. The outer ring grid body comprises multiple outer ring ribs. The multiple inner ring ribs and the multiple outer ring ribs are distributed in a radial manner with the center of the inner ring grid body as the center, the bending directions of the multiple inner ring ribs are consistent, the bending directions of the multiple outer ring ribs are consistent, and the bending directions of the inner ring ribs and the outer ring ribs are opposite. By means of the air outlet grid used for the air purifier and the air purifier, the air outlet amount losses can be reduced, and noise is lowered.

Description

technical field [0001] The invention relates to the technical field of air purification equipment, in particular to an outlet grille for an air purifier and an air purifier. Background technique [0002] The air outlet grille of the air purifier is generally installed at the air outlet of the air purifier, and its main function is air guide rectification and safety protection. Existing air outlet grilles are generally cross-shaped. [0003] The fan installed inside the air purifier is generally a centrifugal fan. The outer cover of the centrifugal fan is provided with a volute, and the volute is provided with an air outlet. The air outlet of the volute is opposite to the air outlet grille. When the centrifugal fan rotates at high speed, it will generate airflow with centrifugal effect. The airflow will be discharged from the air outlet of the volute after being collected by the volute. movement, and part of the airflow diffuses outward along the radial direction of the out...

AI Technical Summary

Problems solved by technology

When the centrifugal fan rotates at high speed, it will generate airflow with centrifugal effect. The airflow will be discharged from the air outlet of the volute after being collected by the volute. movement, and part of the airflow diffuses outward along the radial direction of the outlet grille, so if the outlet grille is a cross-shaped structure, the radially diffused airflow will be resisted by the inner ribs of the outlet grille, resulting in The loss of air volume and the impact between the radially moving airflow and the ribs will increase the noise of the air purifier
