Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

As shown in fig. 1-3.

A multi-effect air filter of an air duct type indoor unit comprises a frame 1. The frame 1 is rectangular, the size of the frame is matched with the air return opening of the air pipe type indoor unit, and the frame can be clamped on the air return opening. The frame 1 is filled with a filter unit I2 and a filter unit II3 which are arranged in parallel, and can filter and purify return air.

The longitudinal section of each frame of the frame 1 is U-shaped with an inward opening, and the thicknesses of the filter unit I2 and the filter unit II3 are adapted to the opening of the frame, so that the filter units can be clamped into the frame. Preferably, an intermediate frame 4 is also included. The cross section of the middle frame 4 is I-shaped, and the middle frame is arranged between the filter unit I2 and the filter unit II3, so that the filter unit I2 and the filter unit II3 can be conveniently installed or detached. Protruding ridges are arranged at two ends of the middle frame 4 and can be clamped into the frame of the frame 1, so that the middle frame is conveniently connected with the frame 1. At the same time, the gap between the upper and lower surfaces of the middle frame 4 is adapted to the thickness of the filter unit I2 and the filter unit II3, so that the filter unit I2 and the filter unit II3 are stably installed. The height of the frame is about 12mm, the folded edge is about 10mm, and the wall thickness is about 1 mm.

The filter unit I2 comprises a formaldehyde filter block. This formaldehyde filter block is rectangular block-shaped, can be made by the double-layered carbon paper of 1mm thickness to trapezoidal upper and lower crisscross arrangement forms network structure, can effectively adsorb the formaldehyde in the air. Preferably, the top of the trapezoid is about 2mm long, the bottom of the trapezoid is about 5mm long, the height of the trapezoid is about 3mm, and the overall thickness of the trapezoid is less than or equal to 10 mm. The formaldehyde filter block can be Queen brand product.

The filter unit II3 comprises a PM2.5 filter layer 31 and a degerming layer 32 which are arranged in an overlapped mode. The PM2.5 filter layer 31 can be made of non-woven fabrics with the thickness of 1mm, is arranged in a V-shaped cross folding mode, and can adsorb a layer of static on the surface and PM2.5 particles in the air.
