DETAILED DESCRIPTION

[0019] Embodiment

[0020] The inverter filter protection window comprises a shell 1, a first filter assembly 2 and a second filter assembly 3, the bottom of the shell 1 is provided with the first filter assembly 2, the first filter assembly 2 is arranged at the bottom of the shell 1, the first filter assembly 2 is provided with an anti-backflow plate 203, and the second filter assembly 3 is arranged at the front position of the shell 1.

[0021] The first filter assembly 2 comprises a first protective wind baffle 201, a first filter cotton layer 202 and the anti-backflow plate 203, the first protective wind baffle 201 is fixedly connected with the shell 1, the first protective wind baffle 201 is provided with the anti-backflow plate 203 towards the inner side of the shell 1, and the first protective wind baffle 201 and the anti-backflow plate 203 are provided with the first filter cotton layer 202 therebetween.

[0022] The first protective wind baffle 201 is a grid type plate body.

[0023] The second filter assembly 3 comprises a mounting plate 301, a second protective wind baffle 302, a second filter cotton layer 303 and a filter cotton fixing plate 304, the mounting plate 301 is mounted at the position on the front of the shell 1, and the mounting plate 301 is sequentially provided with the second protective wind baffle 302, the second filter cotton layer 303 and the filter cotton fixing plate 304 towards the inner side of the shell 1.

[0024] The installation plate 301 is provided with a ventilation groove, and the size and shape of the ventilation groove are matched with the second protective baffle 302.

[0025] The second protective baffle 302 and the filter cotton fixing plate 304 are grid type plate bodies.
