Moisture permeable device, refrigerator and manufacturing method thereof
A moisture permeable device and refrigerator having the same; the moisture permeable device includes a corresponding first surface ( 110 ) and second surface ( 111 ); at least parts of the first surface ( 110 ) and the second surface ( 111 ) of the moisture permeable device define a hollow cavity ( 301 ); through-holes are provided at regions of the first surface ( 110 ) and the second surface ( 111 ) of the moisture permeable device defining the cavity ( 301 ); and regenerated cellulose is accommodated in the cavity ( 301 ). A manufacturing method of the moisture permeable device comprises pouring a regenerated cellulose slurry with a tackifier added thereto into the cavity ( 301 ) to form a moisture permeable film, thus allowing omission of an assembling procedure and a non-woven support.
1. A moisture permeable device, comprises an upper surface and a lower surface corresponding to each other, characterized in that at least parts of said upper surface and lower surface define a hollow cavity; through-holes are provided at regions of said first surface and second surface defining the hollow cavity; and regenerated cellulose mixed with a tackifier is accommodated in said hollow cavity.
2. The moisture permeable device according to claim 1 , characterized in that at least a part of an inner wall of said hollow cavity is a rough surface.
3. The moisture permeable device according to claim 1 , characterized in that there are a plurality of independent hollow cavities.
4. The moisture permeable device according to claim 1 , characterized in that said through-holes have a circular cross section.
5. A refrigerator characterized in that said refrigerator comprises the moisture permeable device as claimed in claim 1 .
6. The moisture permeable device according to claim 1 , wherein said tackifier is high gluten starch.
7. The moisture permeable device of claim 6 wherein at least a part of an inner wall of said hollow cavity is a rough surface.
