Abstract
An ice making unit and a refrigerator having the same are discussed. The refrigerator includes an ice making unit arranged in the ice making compartment, to produce ice, and a refrigeration cycle comprising a refrigerant pipe to supply cooling energy to the ice making compartment. Air present in the ice making compartment is cooled while undergoing direct heat exchange with at least one of the ice making unit and the refrigerant pipe.
Claims18
A refrigerator comprising:
- a body provided with a freezing compartment, a refrigerating compartment and an ice making compartment provided in the refrigerating compartment;
- an ice making unit including an ice making tray to produce ice in the ice making compartment;
- an ice storage container to store the ice made by the ice making unit;
- a refrigerant pipe protruding from an interior wall of the body to supply cooling energy to the ice making compartment;
- a fan to circulate the air of the ice making compartment causing the air to come into contact with the at least one of the ice making unit and the refrigerant pipe, thereby promoting the heat exchange,
- wherein the ice making unit comprises
- a refrigerant-pipe-receiving region underneath the ice making tray, which is adapted to mount the refrigerant pipe inside the ice making unit such that thermal conductivity is established between the refrigerant pipe and the ice making tray, when the ice making unit is installed in the ice making compartment, and
- a drainage duct disposed between the ice making unit and the ice storage container adapted to prevent water drops from the ice making unit falling into the ice storage container, the drainage duct guiding the air of the ice making compartment circulated by the ice making compartment fan to pass through the ice making unit.

A refrigerator comprising:
- a body provided with a freezing compartment, a refrigerating compartment and an ice making compartment provided within the refrigerating compartment, the ice making compartment including an ice making compartment fan to circulate the air of the ice making compartment, at least one suction passage connected to a suction side of the ice making compartment fan, and at least one discharge passage connected to a discharge side of the ice making compartment fan;
- an ice making unit including an ice making tray to produce ice in the ice making compartment, the ice making unit being in the at least one discharge passage;
- and
- a refrigeration cycle comprising a refrigerant pipe including a direct cooling section protruding from an interior wall of the body, the direct cooling section to supply cooling energy to the ice making compartment,
- wherein air present in the ice making compartment is cooled while undergoing direct heat exchange with at least one of the ice making unit and the refrigerant pipe,
- wherein the ice making unit includes
- a refrigerant-pipe-receiving region underneath the ice making tray, which is adapted to detachably mount the direct cooling section of the refrigerant pipe inside the ice making unit such that thermal conductivity is established between the direct cooling section and the ice making tray, when the ice making unit is installed in the ice making compartment,
- a drainage duct formed beneath the ice making tray, the drainage duct being configured to collect water falling from the ice making tray or from the refrigerant pipe and outwardly drain the collected water from the ice making compartment, the drainage duct including an inlet arranged at a leading end of the discharge passage, a first outlet arranged at a trailing end of the discharge passage, and a second outlet arranged at an intermediate portion of the discharge passage.
