BACKGROUND
[0003] Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common
general knowledge in the field.
[0004] In a related art, an air duct is embedded in a side wall of a refrigerating compartment. Since the refrigerating compartment is relatively thin and the relatively long air
duct is communicated to an ice making compartment on a door body from a rear side of a
freezing compartment, a loss of refrigeration capacity in the air duct is relatively great,
thereby greatly influencing an ice making efficiency. In addition, usually, one evaporator is
shared among the ice making compartment, the refrigerating compartment and the freezing
compartment of the refrigerator, and the refrigeration capacity flows back and forth among
the above-mentioned three compartments, which causes flavors of food, especially in the
refrigerating compartment, to transfer to the ice making compartment and to taint ice cubes
therein, and affects qualities and tastes of the ice cubes. Additionally, a plurality of
compartments sharing one evaporator also complicates the structure of the air duct. Also, the
freezing compartment and the ice making compartment are designed to share one evaporator.
Similarly, the flavors of food in the freezing compartment will also taint ice cubes in the ice
making compartment, thereby affecting the qualities and tastes thereof.

the air intake duct is communicated with the ice making compartment 16, and the other end
of the second section 56 of the air intake duct is provided with a second air vent 62. When the
door 12 of the refrigerating compartment is open, the first air vent 60 is separated from the
second air vent 62, thereby disconnecting the first section 54 of the air intake duct from the
second section 56 of the air intake duct; when the door 12 of the refrigerating compartment is
closed, the first air vent 60 is butt-jointed with the second air vent 62 to communicate the first
and second sections 54 and 56 of the air intake duct, thereby transferring the cold air at the
ice making evaporator 24 to the ice making compartment 16 by means of the ice making
blower 22 through the first and second sections 54 and 56 of the air intake duct for making
ice.
[00311 Specifically, the compartment 20 for the ice making evaporator is provided in
