Net cover for air supply equipment

Abstract

The invention relates to a net cover for air supply equipment. The net cover comprises an outer frame body and grating, wherein the grating is located in the outer frame body, and comprises a middle part grating net and a wind guiding grating arranged on the periphery of the middle part grating net. The net cover is characterized in that the middle part grating net consists of a plurality of annular ribs and a plurality of radial ribs; the annular ribs are sequentially and concentrically arranged between the center of the net cover and the wind guiding grating; the radial ribs are used for enabling the annular ribs to be connected; and the inner end part of the section of each annular rib adopts an arrow shape, and the outer end part of the section of each annular rib adopts an oval head shape or an olive-shaped round head shape. In the use process of the net cover disclosed by the invention, the ends facing blades, of the annular ribs adopt the shape of an arrow of which the end is sharp and small, and the other ends of the annular ribs adopt an oval shape or an olive-shaped round head shape, so that the wind outlet resistance of the grating of the net cover is effectively reduced, the outlet loss is reduced, the wind exhausting capacity is increased, namely that the noise is low and the structure is firm. The net cover disclosed by the invention can be widely applied to equipment of various air conditioners, various fans and the like.

Description

technical field [0001] The invention relates to the field of air supply equipment, in particular to a net cover (protective grille) for an air conditioner outdoor unit and a fan. Background technique [0002] At present, the protective grille or net cover at the air outlet of traditional air supply equipment (such as outdoor units of air conditioners and fans) is set based on safety factors, and does not really consider the outdoor air circulation. The configuration of such traditional grilles or grilles has a great impact on the performance of fans and air conditioners, which is not conducive to improving energy efficiency. In particular, the introduction of the new EU safety regulations has unprecedentedly strict protection levels for the grille. The new safety regulations lead to a stronger and safer structure of the air outlet grille and grille, which invisibly increases the air outlet resistance of the airflow. The increase in resistance leads to The performance of the...

Problems solved by technology

The ribs of this kind of protective net made of synthetic resin are usually made thicker, and the cross-section is a rectangular or parallelogram structure, which not only tends to generate greater noise during use, but also has a large wind resistance, resulting in a The performance of the equipment is degraded and the noise is loud
