TECHNICAL FIELD
[0002] The present invention relates to the field of home appliances, and in particular,
to a refrigerator with an ice making function.
BACKGROUND
[0003] 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.
