First, the application makes based on the following understanding of utility model people:
The screen pack of air conditioner has countless mesh, and along with increasing dust is attached on screen pack fiber, the mesh of screen pack reduces gradually, even blocks.As shown in Figure 1, when light beam is radiated at the side of screen pack 100, the mesh of a part of light transmission screen pack 100 is irradiated to the opposite side of screen pack, i.e. transmitted light, and meanwhile, another part light is filtered the side that screen pack 100 is returned in net 100 diffuse reflection, i.e. reflected light.And along with the reducing and block of mesh of screen pack, the light through mesh is fewer and feweri, the light of reflection gets more and more, and namely transmitted light is more and more weak, and reflected light is more and more stronger.
Based on this, the utility model embodiment proposes a kind of dust-full pick-up unit of screen pack of air conditioner, the dust-full pick-up unit of screen pack of another kind of air conditioner, a kind of cleaning systems of air conditioner and the cleaning systems of another kind of air conditioner.
