  • Patent number: 12339053
    Abstract: Provided is an air-cooled refrigerator with an evaporator at the bottom of a cabinet thereof. The air-cooled refrigerator includes: a cabinet with a bottom liner; a partition cover plate transversely arranged in the bottom liner to divide the bottom liner into a storage space and a cooling chamber below the storage space; a return air cover arranged at the front of the cooling chamber and provided with at least one front return air inlet; and an evaporator, which is in a flat cuboid shape and is mounted in the cooling chamber in a manner of inclining upwards from front to back, where a front portion of a top surface of the evaporator, the partition cover plate and the return air cover define a frost-accommodating space, such that some of the air that enters from the front return air inlet enters the evaporator from the frost-accommodating space.

  • Publication number: 20250003673
    Abstract: A refrigerator with a reserved installation space arranged in a bottom heat dissipation compartment includes a cabinet with a heat dissipation compartment set at its rear bottom; a compressor, a duct assembly, and an evaporating tray sequentially arranged within the heat dissipation compartment along a horizontal direction of the cabinet, and the heat dissipation compartment reserves an installation space on one side away from the duct assembly relative to the evaporating tray, the installation space is equipped with one or more mating structures, each of which is used to install an auxiliary functional component. This design optimizes the layout of devices within the confined space of the heat dissipation compartment to fulfill the purpose of reserving installation space. This provides installation space for expanding the functionality of different refrigerator models, enhancing product competitiveness and saving development costs.

  • Publication number: 20230280088
    Abstract: An air-cooled refrigerator comprises a bottom liner, a fan bottom shell, an air duct cover plate, and fan blades. A cooling chamber and a storage space are defined in the bottom liner. The fan bottom shell 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 rear wall of the bottom liner. The fan upper cover obliquely extends downward from a lower end of the back plate portion into the cooling chamber, covers the fan bottom shell 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.
