Humidity controller

The patent applies local quality by creating a skin layer with different thermal conductivity properties than the core material. The skin layer has lower thermal conductivity to prevent heat from reaching the core too quickly, while the core maintains high moisture absorption capability. This local differentiation resolves the contradiction by allowing the material to simultaneously achieve high moisture absorption while controlling thermal conductivity through the specialized skin layer structure.

The patent applies preliminary anti-action by forming a skin layer with reduced thermal conductivity before the heating process begins. This skin layer acts as a protective barrier that prevents the rapid heat conduction from causing the formation of a hydrophobic surface layer. By having this protective layer in place beforehand, the patent prevents the adverse effect of surface hydrophobization while still allowing efficient heat transfer to occur through controlled pathways.

The patent applies segmentation by dividing the dehumidifying material into distinct functional zones: a skin layer with lower thermal conductivity for heat retention and a core region with high moisture absorption capability for moisture release. The skin layer is segmented as a separate functional component that specifically handles heat management, while the core handles moisture absorption and release. This segmentation allows each zone to optimize its function without interfering with the other, resolving the contradiction between heat retention and moisture release efficiency.
