Title:
ELECTRET MEMBRANE, PREPARATION METHOD, REFRIGERATOR BODY ASSEMBLY AND REFRIGERATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/126452
Kind Code:
A1
Abstract:
An electret membrane (100), a preparation method, a refrigerator body assembly (200) and a refrigeration apparatus (300). The electret membrane (100) comprises: an electret material matrix (102); and a metal electrode (104), which is arranged on one side of the electret material matrix (102) and is attached to the electret material matrix (102). The electret membrane (100) can be electrically polarized insofar as the electret membrane is not externally connected to a power source, and can form an electrostatic field; and when the electret membrane is applied to a fresh keeping function of apparatuses, such as a refrigerator, the fresh-keeping structure of the electrostatic field can be simplified, thereby reducing the costs for generating the electrostatic field, and facilitating the realization of low-cost and high-reliability electrostatic field fresh keeping for fresh-keeping apparatuses, such as the refrigerator.
