Description

A regional precise temperature control structure, method and refrigerator

Technical Field

The present invention relates to the technical field of temperature regulation, and in particular to a regional precise temperature control structure, method and refrigerator.

Background Art

A refrigerator is a refrigeration device that keeps a constant low temperature. It is also a civilian product that keeps food or other items in a constant low temperature and cold state. The refrigerator has a compressor, an ice maker, a cabinet or box for freezing, and a storage box with a refrigeration device. As people's living standards continue to improve, some meat and fresh food need to be preserved in a freezer, but the low-temperature preservation temperature of different foods is different. In order to meet the conditions of storing different foods at different temperatures, a refrigerator with zoned temperature control was born.

A refrigerator with zoned temperature control can achieve different refrigeration temperatures in different areas, so that food with different refrigeration temperatures can be stored. However, when existing refrigerators achieve single or multi-temperature control, they either need to control multiple fans to control the temperature of the corresponding areas to achieve single or dual temperatures; or they need a heating device for temperature compensation. These two types of refrigerators with zoned temperature control have complex structures, which makes control more troublesome and costly.
