Description

Technical Field

[0001] This utility model relates to the technical field of refrigerator door sealing structure, and in particular to a waterproof door and refrigerator with multiple sealing structures. Background Technology

[0002] Modern refrigerators are typically divided into two sections: a freezer compartment and a refrigerator compartment, separated by a partition. An evaporator and a fan chamber connected to the evaporator are located in the rear wall of the refrigerator. An air outlet duct connected to the fan chamber runs between the freezer and refrigerator compartments. This air outlet duct branches off within the refrigerator's compartments and connects to the freezer and refrigerator compartments respectively. The fan blows the cooled air from the evaporator directly into the refrigerator and freezer compartments through the air outlet ducts. To control the cooling of the refrigerator and freezer compartments, dampers are installed in the air outlet ducts before the branching points to control the flow of cold air.

[0003] During long-term low-temperature operation of a refrigerator, water vapor will condense. Water vapor can enter through the gap at the outlet of the damper wire. Although the gap is very small and the amount of water vapor is also very small, long-term water vapor intrusion will still affect the electrical components such as the damper motor, causing the damper to malfunction. Utility Model Content

[0012] Preferably, the gantry sealing part is a sealing rib, and multiple sets of first grooves are continuously formed in the sealing rib for accommodating multiple wires of the damper.

[0013] Preferably, the sealing part of the cover plate is a sealing soft rubber, and multiple sets of second grooves are continuously formed in the sealing soft rubber.

[0014] Preferably, when the gantry sealing part and the cover plate sealing part are combined with each other, the corresponding first wire groove and the second wire groove wrap around the multiple wires of the sealing damper one by one.

[0015] Preferably, both the first and second wire grooves are arc-shaped, wrapping the wires of the sealing damper one by one.
