The present disclosure relates to the field of refrigerator equipment, in particular to a refrigerator having a height-adjustable rack, comprising a door, a guide rail vertically formed on the door, a number of adjusting grooves formed on the guide rail, a rack and a limiting groove arranged on the rack. The rack is assembled on the guide rail through the limiting groove and is able to move up and down. A guide portion, a stop block and a reset device are provided on the rack. The reset device drives the stop block to enter an adjusting groove along the guide portion such that the rack is supported at any height. A manipulating member is further provided within the rack. The interlocking of the manipulating member and the stop block is realized through the mutual pushing of inclined planes.
