As shown in fig. 1, the grid 100 includes a plurality of grid bars 1, and the grid bars 1 are arranged in a staggered manner, that is, the grid bars 1 of the grid 100 are connected to each other in a staggered manner, so that the connection strength between the grid bars 1 can be increased, and compared with the arrangement mode that the grid bars 1 are arranged in parallel, the grid 100 of the present embodiment can be more reliable in use. In the description of the present invention, "a plurality" means two or more.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Each of the grill bars 1 has an inner surface and an outer surface which are oppositely disposed, and it is understood that adjacent grill bars 1 may define therebetween an airflow passage along which an airflow may flow from one side of the grill 100 to the other side of the grill 100, and the inner surface and the outer surface of each grill bar 1 are spaced apart in the flow direction of the airflow. Here, it should be explained that, when the grill 100 is installed on the housing of the air conditioner, a side surface facing the inside of the housing is an inner surface of the grill bars 1, and an outer surface opposite to the inner surface is an outer surface of the grill bars 1.
