Embodiment Construction

[0042] The invention provides a refrigerating and freezing device and a control method thereof. figure 1 is a schematic structural diagram of a refrigerating and freezing device according to an embodiment of the present invention, figure 2 It is a partial structural schematic diagram of a refrigerating and freezing device according to an embodiment of the present invention. The refrigerating and freezing device 1 of the embodiment of the present invention includes a box body 10 and a door body 20 . The box body 10 defines a refrigerated compartment 110 and an air supply duct (not shown) for delivering cooling airflow to the refrigerated compartment 110 , and the air supply duct may be located behind the refrigerated compartment 110 . An evaporator for providing cooling airflow and a fan for driving the airflow to circulate may be arranged in the air supply duct.

[0043] There are multiple storage spaces in the refrigerated compartment 110 . Specifically, the refrigerated ...

Abstract

The invention relates to a refrigerating and freezing device and a control method thereof. The control method comprises the steps of: obtaining a brightness state of each-layer storage space in a refrigerating chamber at the moment of opening a door body; obtaining the brightness state of each-layer storage space in the refrigerating chamber again after the door body is closed and before a light source in the refrigerating chamber is turned off; comparing the brightness states obtained twice at the moment of opening the door body and after closing of the door body to determine if a storage state of the storage space is changed; indicating that new objects are placed in the storage space if the storage state of the storage space is changed, and judging if the temperature in the storage space is higher than a first preset temperature threshold or not; and communicating an air supply port corresponding to the storage space to the air supply way if the temperature in the storage space is higher than the first preset temperature threshold. Precise layered air supply is realized; and the refrigerating effect and the refrigerating efficiency are improved.

Description

technical field [0001] The invention relates to household electrical appliances, in particular to a refrigerating and freezing device and a control method thereof. Background technique [0002] Existing refrigerating and freezing devices usually have a plurality of storage compartments, and the storage environments of each storage compartment are different, and the required cooling capacity is also different. Therefore, in the prior art, each storage compartment is usually The air volume is distributed in different rooms to achieve the purpose of different storage environments. [0003] For the same storage compartment, there is no difference in the air volume delivery in different areas. However, a plurality of shelves are usually arranged in the storage compartment (especially the refrigerated compartment), thereby forming a multi-layer storage space. According to the user's personal preferences and actual needs, the storage conditions of each storage space will be diffe...
