Refrigerator having evaporator disposed at bottom of refrigerator body

A refrigerator having an evaporator disposed at the bottom of a refrigerator body, comprising:

• the refrigerator body, having a bottom inner liner, the bottom inner liner defining a cooling compartment and a storage space, and the cooling compartment being disposed below the storage space;
• and
• the evaporator, arranged in the cooling compartment and placed inclinedly along the depth direction of the refrigerator with respect to the horizontal direction, with the direction of inclination being upward from front to back;
• wherein a bottom wall of the bottom inner liner comprises:
• a plane-shaped first inclination portion, disposed inclinedly downward from a front end of the bottom wall of the bottom inner liner from front to back;
• a recessed portion, disposed at a rear side of the first inclination portion and configured to be inclined upward from a transverse middle to two sides along a transverse direction of the refrigerator to form a drain hole in the transverse middle, both side surfaces of the recessed portion along the transverse direction and both side surfaces of the recessed portion along the depth direction of the refrigerator being inclined-plane-shaped, and the drain hole being configured to drain water from the cooling compartment;
• and
• a plane-shaped second inclination portion, disposed inclinedly upward from a rear end of the recessed portion from front to back and configured to support the evaporator, an inclination angle of the evaporator being consistent with that of the second inclination portion with respect to a horizontal plane, and a front end of the evaporator abutting against the first inclination portion so that water on the evaporator is gathered at the recessed portion, and a position of the drain hole along the front and rear direction of the refrigerator body being at a front portion of the evaporator;
• wherein the recessed portion provided with the drain hole is formed in a connecting position of the first inclination portion and the second inclination portion, so that the drain hole is used to drain condensed water of the evaporator;
• wherein the bottom wall of the bottom inner liner further comprises:
• a plane-shaped third inclination portion, disposed inclinedly upward from a rear end of the second inclination portion from front to back and having an inclination angle greater than that of the second inclination portion;
• wherein the refrigerator further comprises a refrigeration fan, disposed on the third inclination portion and configured to promote formation of a refrigeration airflow sent to the storage space via the evaporator;
• wherein the refrigeration fan is a centrifugal fan which comprises a volute and an impeller disposed in the volute, the volute is fixed to the third inclination portion with a bottom face of the volute, opposite to a suction inlet of the volute, being parallel to the third inclination portion, and the suction inlet of the volute faces a front upper side to suck air undergone heat exchange through the evaporator by utilizing the impeller.
