Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 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.
