摘要： An air-cool refrigerator, comprising a bottom liner, an evaporator, a water receiving tray, and a heating wire. A cooling chamber located at the bottom of the bottom liner is defined inside the bottom liner, and a water receiving tank is further formed on the bottom wall of the bottom liner; a water drainage outlet is formed at the bottom of the water receiving tank; the evaporator is provided in the cooling chamber, and is configured to cool an air flow entering the cooling chamber to form a cooled air flow; the water receiving tray is provided between the evaporator and the bottom wall of the bottom liner, and is configured to receive water on the evaporator, and a plurality of through holes are formed in a region of the water receiving tray facing towards the water receiving tank; the heating wire is provided between the water receiving tray and the evaporator in a coiled manner, and is configured to provide heat for defrosting of the evaporator, and the heating wire has an extension portion extending to the water receiving tank through the through holes. According to the extension portion of the present invention, the distance between the heating wire and the water drainage outlet can be shortened, and large-volume ice at the water drainage outlet can be melted in time, thereby improving the water drainage efficiency; moreover, the present invention has a simple structure and is easy to popularize.

摘要： An air-cooled refrigerator comprises a bottom inner compartment, a fan bottom housing, an air duct cover plate, and fan blades. A cooling chamber and a storage space are defined in the bottom inner compartment. The fan bottom housing is arranged at a rear portion of the cooling chamber. The air duct cover plate comprises a back plate portion and a fan upper cover. The back plate portion is disposed in front of a back wall of the bottom inner compartment. The fan upper cover obliquely extends downward from a lower end of the back plate portion into the cooling chamber, covers the fan bottom housing and is fastened thereto. The back plate portion and the fan upper cover are integrally formed. The fan blades are arranged in a fan cavity, and enable formation of a refrigeration airflow discharged from the cooling chamber to an air supply duct. The back plate portion and the fan upper cover of the present invention are integrally formed to facilitate modularization, thereby simplifying installation processes and reducing costs, ensuring the stability of the whole air duct structure, and achieving high practicability and wide applicability.
