1. A refrigerator, comprising:
a cabinet in which a cooling chamber located at a lower part and at least one storage compartment located above the cooling chamber are defined;
an evaporator arranged in the cooling chamber and configured to cool an airflow entering the cooling chamber to form a cooling airflow, wherein a water pan is formed on a bottom wall of the cooling chamber below the evaporator, and used for receiving defrosted water generated by the evaporator, a slope structure is formed on an upper surface of the water pan, and the evaporator is obliquely arranged on the water pan; and
at least one air supply fan disposed in the cooling chamber and completely below the storage compartment, the air supply fan being configured to cause an airflow to flow within the cooling chamber and located downstream of the evaporator on an airflow flowing path,
wherein a water outlet is formed in a tail end of a lower part of the slope structure of the water pan,
wherein the water pan is formed by the bottom wall, inclining downwards from front to rear, of the cooling chamber, and the water outlet is close to a compressor chamber of the refrigerator,
wherein an inclined section is formed on the bottom wall of the cooling chamber below the air supply fan, the air supply fan being arranged on the inclined section, and the inclined section and the air supply fan wholly inclining upwards from front to rear, and the water outlet is formed in a joint of the inclined section and the water pan,
wherein the evaporator is wholly obliquely arranged on the water pan in the shape of a flat box, and is configured such that a long edge of a cross section of the evaporator is parallel to a rear wall of the cabinet, and a short edge of the cross section of the evaporator is perpendicular to the rear wall of the cabinet.
