A refrigerator having a storage space formed on a door body, comprising:

• a refrigerator body, wherein at least a first storage space is defined in the refrigerator body, and the first storage space has a forward opening;
• an inner-layer door, pivotally disposed at a front portion of the forward opening and comprising:
• a storage container body, wherein the storage container body defines a second storage space, the second storage space is provided with an opening in one side away from the refrigerator body, the storage container body is provided with an air supply port in one side toward the forward opening, and low-temperature air in the first storage space is introduced into the second storage space via the air supply port to implement refrigeration inside the second storage space;
• a sterilization module, disposed at the air supply port and configured to sterilize the air passing through the air supply port;
• and
• an inner-layer door frame, disposed on the periphery of the storage container body;
• and
• an outer-layer door, pivotally disposed on one side of the inner-layer door frame away from the refrigerator body and configured to open and close the opening of the second storage space;
• wherein the inner-layer door further comprises an air supply assembly, disposed at the air supply port and configured to promote formation of a refrigerating airflow supplied from the first storage space to the second storage space;
• wherein the storage container body comprises:
• a container main body, wherein the container main body is configured to constitute the second storage space;
• and
• a housing, wherein the housing covers a back of the container main body to serve as a rear wall of the storage container body;
• the housing and the top of the container main body form a mounting chamber located above a top wall of the container main body;
• wherein the air supply port is formed in the top of the housing, and the air supply assembly is disposed inside the mounting chamber and opposite the air supply port;
• wherein the air supply assembly comprises:
• a fan bracket, disposed at the top wall of the container main body and extending upwards from the top wall of the container main body;
• and
• an air supply fan, installed on the fan bracket with a vertical gap between the air supply fan and the top wall of the container main body;
• wherein the sterilization module is pre-started before the air supply fan is turned on, and turning off of the sterilization module is delayed after the air supply fan is turned off.
