Refrigerator

A refrigerator comprising:

• a first storage defining a first storage space therein;
• a second storage disposed below the first storage, defining a second storage space therein and includes a base forming a bottom face of the second storage space;
• and
• a drawer disposed in the second storage space in an extendable and retractable manner and including a loading portion therein;
• and
• an actuator for extending and retracting the drawer, for ascending the loading portion when the drawer is extended from the second storage space, and for descending the loading portion prior to the drawer retracted into the second storage space,
• wherein the actuator includes:
• an extension and retraction actuator for extending and retracting the drawer from and into the second storage space;
• and
• an ascending and descending actuator linked to the extension and retraction actuator to ascend the loading portion when the drawer is extended from the second storage space and to descend the loading portion prior to the drawer retracted into the second storage space,
• wherein the extension and retraction actuator includes:
• an extension guide disposed at the base;
• and
• an extension bar guided by the extension guide and having an extension distance shorter than an extension distance of the drawer, wherein the extension bar is connected to the ascending and descending actuator,
• wherein the ascending and descending actuator includes:
• a lower frame disposed in the drawer;
• an upper frame disposed above the lower frame, and seating the loading portion thereon;
• pairs of first and second ascending and descending links respectively disposed at both sides of each of the upper frame and lower frame, wherein the first and second ascending and descending links at each of the both sides of each of the upper frame and the lower frame cross each other to be pivotable;
• and
• slide bars respectively extend between ends of the first and second ascending and descending links at one of the both sides of each of the upper frame and lower frame and ends of the first and second ascending and descending links at the other of the both sides of each of the upper frame and lower frame, and
• wherein the extension bar is connected to a front lower slide bar of the slide bars between the pairs of first and second ascending and descending links.
