Embodiment Construction
[0025] figure 1 is a schematic exploded view of a branch air supply device according to an embodiment of the present invention. Such as figure 1 As shown, the embodiment of the present invention provides a branch air supply device 10 . The branch air supply device 10 includes a housing, an adjusting member 14 , a driving device 18 and a pre-tightening force applying device 19 . The housing has at least one air inlet and multiple air outlets, so that air flows into the housing through the at least one air inlet, and flows out of the housing through the multiple air outlets in a controlled manner. The adjusting member 14 has at least one shielding part, at least one shielding part is rotatably arranged in the casing, and is configured to shield a plurality of air outlets in a controlled manner, so as to adjust the respective air outlet areas of the plurality of air outlets, so that The flow of cold air flowing in from the air outlet is controllably distributed to multiple air...

The present invention provides a branch air supply device, which comprises: a housing with at least one air inlet and multiple air outlets; an adjustment member with at least one shielding part, at least one shielding part is rotatably arranged in the housing , configured to cover a plurality of air outlets in a controlled manner, so as to adjust the respective air outlet areas of the plurality of air outlets; the driving device, configured to drive the adjustment member to rotate; and the pre-tightening force application device, installed between the adjustment member and the housing Between them, it is configured to apply a pre-tightening force on the adjusting member at least when the adjusting member rotates in one rotating direction, which is opposite to the rotating direction. The branch air supply device and the refrigerator of the present invention can reasonably distribute the cold air according to the cooling capacity requirements of different storage compartments or different storage spaces of a storage compartment, so as to enhance the freshness preservation of the refrigerator performance and operating efficiency, and remains smooth during adjustments.
Description
technical field [0001] The invention relates to a refrigeration device, in particular to a branch air supply device for a refrigerator. Background technique [0002] Generally speaking, an air-cooled refrigerator generates cold air through a built-in evaporator, and the cold air circulates through an air duct to each storage compartment of the refrigerator to achieve cooling. For air-cooled refrigerators, the freshness of food largely depends on whether the air circulation in the storage room is reasonable. If the cold air flows randomly through the air duct, it is easy to cause too much or insufficient air volume entering the storage rooms, making the temperature distribution in the storage rooms unbalanced, and the operating efficiency of the refrigerator will also be reduced. Therefore, it is necessary to accurately distribute and control the flow of cold air entering each storage compartment. [0003] Similarly, in order to optimize the storage space, a single storage ...
