Title:
REFRIGERATION DEVICE HAVING MAGNETIC FIELD FRESHNESS-PRESERVING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/109410
Kind Code:
A1
Abstract:
A refrigeration device having a magnetic field freshness-preserving apparatus, comprising: a box body in which a storage chamber is defined, a back part of the storage chamber being provided with a refrigeration air duct used to provide a refrigeration airflow; and a magnetic field freshness-preserving apparatus, disposed inside the storage chamber and provided with a magnetic field component used to apply a magnetic field to a freshness-preserving space inside the storage chamber. The magnetic field freshness-preserving apparatus comprises: a barrel body, an air intake port and an air return port in communication with the refrigeration air duct being formed at a rear part thereof; and a drawer, which is retractably disposed in the barrel body and in which a freshness-preserving space is defined. In addition, the magnetic field freshness-preserving unit is configured to form a surrounding air duct that allows airflow to flow from the air inlet port sequentially through a top wall of the barrel body, a front baffle of the drawer, and a space below a bottom plate of the drawer, and back to the air return port, so as to refrigerate the freshness-preserving space. The present refrigeration device reduces temperature fluctuations in the freshness-preserving space, to improve the freshness-preserving effect on foods in the freshness-preserving space.
