a refrigerator

Abstract

The present invention provides a refrigerator comprising: a main body having at least one compartment for storing food; a cool air supply device configured to supply cool air to keep the compartment at a predetermined temperature; an air duct , the air duct is used to deliver cold air to each room; the air duct includes at least two air duct units arranged in series, and the air duct unit includes at least two cold air branches arranged in parallel, and each cold air branch includes an inlet port and At the outlet end, the outlet end of the cold air branch is connected to the compartment; in any air duct unit, a flow regulating component is arranged on the cold air branch, and the flow regulating component is used to adjust the flow of cold air in the cold air branch. The refrigerator adopting the technical solution of the present invention can meet the different degrees of cooling requirements in each room of the refrigerator by setting multi-stage air duct units, and can control the flow of cold air to ensure that the food in the refrigerator has a good fresh-keeping effect.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a refrigerator. Background technique [0002] A refrigerator is a device designed to store food at low temperatures and is configured for refrigerated or frozen storage of food. To this end, the refrigerator may include a cold air supply device in which a cooling or refrigeration cycle has been implemented, the cold air supply device being configured to subject a refrigerant to a compression-condensation-expansion-evaporation process. Cool air is generated when refrigerant circulates in the cooling cycle. [0003] There are several compartments used for storage in the refrigerator, and the cold air generated by the evaporator of the cold air supply device is transported to each compartment through the air duct, and each compartment stores different foods according to different temperature settings.

AI Technical Summary

Problems solved by technology

[0003] There are several compartments used for storage in the refrigerator, and the cold air generated by the evaporator of the cold air supply device is transported to each compartment through the air duct, and each compartment stores different foods according to different temperature settings. A single air duct directly transports cold air to each room, so that the temperature of each room is uneven and the temperature difference is large. Specifically, during the actual use of the user, the type and storage of food stored in each refrigerator room The volume is different, and the heat load is also different. Therefore, the temperature requirements of different spaces in each room of the refrigerator are different. Conventional air ducts cannot distribute cold air to each room according to the heat load of the rooms, thus satisfying the requirements of the rooms. The food in the room has different refrigeration needs, and the air intake cannot be adjusted automatically and the air outlet can be controlled for precise air supply, which usually makes the temperature control of the refrigerator inaccurate, and the temperature of the refrigerator is uneven, resulting in poor food preservation effect.
