Title:
MAGNETIC FIELD FRESHNESS-PRESERVING REFRIGERATOR AND REFRIGERATION CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/231976
Kind Code:
A1
Abstract:
Provided are a magnetic field freshness-preserving refrigerator and a refrigeration control method therefor. The magnetic field freshness-preserving refrigerator comprises a refrigerator body internally defining a storage compartment; a refrigeration air channel for providing refrigeration airflow to the storage compartment; a refrigeration system used for generating refrigeration airflow; a magnetic field freshness-preserving device arranged in the storage compartment, the magnetic field freshness-preserving device being provided with an air inlet and an air return opening which are used for establishing communication with the refrigeration air channel to perform air cooling on a magnetic field freshness-preserving space. The refrigeration control method comprises: determining whether a state of the magnetic field freshness-preserving space meets a preset rapid refrigeration initiation condition; if yes, performing rapid refrigeration on the magnetic field freshness-preserving device until the state of the magnetic field freshness-preserving space meets a preset rapid refrigeration cessation condition; after rapid refrigeration of the magnetic field freshness-preserving device is completed, performing one or more phases of a transitional refrigeration procedure on the magnetic field freshness-preserving device; and after transitional refrigeration is completed, controlling the refrigeration system to normally refrigerate the magnetic field freshness-preserving device. The present solution can implement rapid and stable refrigeration of the magnetic field freshness-preserving device.
