Benefits of technology

[0011] Therefore, an object of the present invention is to provide a bottom drawer type refrigerator having a basket lift device capable of enhancing users' convenience by lifting a position of the basket in such a manner that when a basket disposed at a lower portion of a main body of the refrigerator is drawn out, it is lifted upwardly.

Problems solved by technology

However, the conventional bottom drawer-type refrigerator has a problem in that, because the installation position of the basket is too low, a user must lower his / her posture, that is, for example, the user must bend his / her back or crouch down in order to put in or take out the food items, causing users' inconvenience.
