Description

Refrigerator {Refrigerator}

An embodiment of the present invention relates to a refrigerator.

More specifically, the present invention relates to a refrigerator, and more particularly, to a refrigerator that improves the structure of a cool air duct to simplify a structure of a cool air flow path from a freezing chamber to an ice making chamber, In the refrigerator.

Generally, a refrigerator has a plurality of storage chambers for storing the foods to be frozen or refrigerated, and one side of the storage chamber is opened to receive and retrieve the food.

In addition, recently, a refrigerator is provided with a dispenser which allows a user to take out water or ice. The dispenser may be connected to a water tank for storing the water to be taken out.

The refrigerator is provided with an ice making chamber for supplying water to produce ice, and the ice making chamber can be provided in the refrigerator body or the refrigerator door.

In addition, when the ice-making chamber is provided on the refrigerating chamber side, the ice-making chamber must be formed so as to be adiabatic with the outside in order to provide a low-temperature environment. In addition, a flow path may be formed on the side surface of the ice making chamber and the side surface of the refrigerator so that cool air can be introduced or discharged from the freezing chamber.

That is, a cool air duct may be provided between the freezing chamber and the ice making chamber such that the cool air formed in the freezing chamber is moved to the ice making chamber.

When the ice making chamber is provided in the ice making chamber door, the ice making chamber may communicate with the freezing chamber in a state where the ice making chamber door is closed.

In a bottom-freezer type refrigerator in which a conventional refrigerator, in particular, a freezer compartment is provided under the refrigerator, a partition for partitioning the freezer compartment and the refrigerating compartment is provided between the freezer compartment and the refrigerating compartment.

Further, the cool air duct is arranged to be connected to the ice making chamber through the partition from the freezing chamber.

As a result, the refrigerator has a structure in which cool air formed from the freezing chamber is supplied to the ice-making chamber through the partition, thereby forming dew or ice in the partition.

In order to solve this problem, a heater for supplying heat for preventing dew formation and freezing is required in the partition.

In this case, in manufacturing the refrigerator, additional cost is required to provide the heater, and power consumption due to use of the heater is increased.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a refrigerator which improves the structure of a cool air duct provided in a refrigerator and simplifies a structure of a cool air channel connected from a freezing chamber to an ice making chamber.

It is another object of the present invention to provide a refrigerator in which a cooler duct is extended from a freezing chamber to a side of a refrigerator inner case so that a heater device provided in the compartment is not required and thus the material cost and power consumption required for manufacturing a refrigerator can be reduced .

According to an aspect of the present invention, there is provided a refrigerator comprising: a main body including a storage chamber formed by an inner case, a freezing chamber disposed at a lower portion of the storage chamber, and a refrigerating chamber disposed at an upper portion; An ice maker provided in the interior of the refrigerator compartment or on a rear surface of the door for producing ice; And a supply duct for supplying cool air to the ice making device from the freezing chamber, wherein one end of the supply duct is connected to the freezing room inner case, and the supply duct extends upward along the outer side of the freezing room inner case .

According to another aspect of the present invention, there is provided a refrigerator comprising: an outer case forming an outer appearance; a freezing compartment inner case provided inside the outer case to form a freezing compartment at a lower portion thereof, A refrigerator compartment inner case provided inside the outer case to form a refrigerating compartment at an upper portion thereof and to form a duct supply portion selectively communicating with the icemaker; A partition for partitioning the freezer compartment inner case and the refrigerating compartment inner case; And a supply duct communicating with the cool air supply hole and extending outwardly of the freezer compartment inner case to supply cool air to the ice maker.

According to the refrigerator constructed as described above, the structure of the cool air duct provided in the refrigerator can be improved to simplify the structure of the cool air channel connected from the freezing chamber to the ice-making chamber.

Further, since the cool air duct extends from the freezing chamber to one side of the inner case of the refrigerator, the heater device provided in the partition is unnecessary, thereby reducing the material cost and power consumption required for manufacturing the refrigerator.
