AI Technical Summary
Existing wall-mounted air conditioners use a double-track structure for cleaning filters, which results in a complex structure and high cost. On the other hand, using a single-track system with a roller to roll up the filter results in a thicker overall unit and a poorer appearance.
The single-layer track design divides the track into two parts: the top and the front. When the filter is not cleaned, it is in the top track; when cleaned, it is in the front track. The overall track is simple and the structure is straightforward. There is always a portion of the filter in both the top and front tracks, which improves reliability.
This design achieves a simpler structure, reduced overall thickness, improved reliability of the filter screen during operation, and reduced material costs and friction noise.
