Description

Drainage assembly and refrigerator Technical Field The application relates to the technical field of refrigerator defrosting water discharge, in particular to a drainage assembly and a refrigerator. Background In the defrosting process of the refrigerator, a large amount of condensed water (defrosting water) is generated after the frost on the surface of the evaporator is melted, and the water is discharged out of the refrigerator, and the internal air pressure of the refrigerator is smaller than the external air pressure during refrigeration, so that a device capable of balancing the internal air pressure and the external air pressure of the refrigerator is needed. The prior art utilizes the drainage assembly to simultaneously solve the problem that the drainage of defrosting water is balanced with the internal and external air pressure of the refrigerator. The existing drainage assembly comprises a drainage pipe, and the drainage pipe is provided with a vent hole, so that defrosting water can be discharged through the drainage pipe, and external air can enter through the vent hole, so that the internal and external air pressure of the refrigerator can be balanced. However, in the method, the outside of the refrigerator is always communicated with the position of the evaporator in the refrigerator, so that the hot air outside can always exchange heat with the cold air at the position of the evaporator, and the energy consumption of the refrigerator can be increased.
