Title:
MAGNETIC FIELD FRESHNESS-PRESERVING STORAGE CONTAINER, AND REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2023/016226
Kind Code:
A1
Abstract:
A magnetic field freshness-preserving storage container (200) and a refrigerator (10). The magnetic field freshness-preserving storage container (200) comprises: a storage box (210), in which a storage space (212) for holding stored objects is defined; two uniform magnetization plates (221), which are made of a magnetically conductive material and are respectively arranged corresponding to a set of side walls of the storage box (210) that are correspondingly arranged opposite each other; and two sets of electromagnetic components (222). Each set of electromagnetic components (222) is arranged corresponding to one uniform magnetization plate (221) and forms an electromagnetic field after being electrified, and the magnetic field distribution of the electromagnetic field can be changed by means of the uniform magnetization plates (221), such that the electromagnetic field is distributed more uniformly in the storage space (212). Since the electromagnetic field is distributed more uniformly in the storage space (212), stored objects can have the same storage quality. In addition, the uniform magnetization plates (221) can save on the consumption of magnetic materials. The refrigerator (10) provides a new freshness preservation function, which meets the increasing demand of users for using smart refrigerators, and further meets the quality requirements of users for smart homes and smart life.
