BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a refrigerator having a cool air duct for an icemaker,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a refrigerator having a cooler duct for an ice maker, and more particularly to a refrigerator having a cooler duct for an ice maker capable of selectively supplying cool air supplied to a freezer to an ice maker or a freezer.

Generally, a refrigerator is a device that keeps the food in a fresh state for a predetermined period by reducing the temperature of the refrigerating chamber and the freezing chamber as the refrigerant repeats a refrigerating cycle in which the refrigerant compresses - condenses - expands - evaporates.

The refrigerator includes a refrigerator body having a freezer compartment and a refrigerating compartment so that food can be stored in a low temperature state, and a refrigerator door that rotatably rotates the front surface of the refrigerator body.

In addition, the freezing chamber includes an icemaker for forming a certain type of ice, and a cool air duct for supplying cool air smoothly to the icemaker.

Hereinafter, a refrigerator having a cooler duct for an ice maker according to the related art will be described with reference to FIG.

A refrigerator main body 2 partitioned into a freezing compartment and a refrigerating compartment; respective refrigerator doors 4 and 6 for opening and closing the freezing compartment and the refrigerating compartment so that the refrigerating compartment and the refrigerating compartment can be opened and closed; an ice maker 25 installed in the freezing compartment door 6; And cool air ducts 12 and 14 for guiding the cool air generated from the evaporator 8 installed on the rear wall of the refrigerator body 2 to the ice maker 25. [

That is, the cool air generated from the evaporator 8 passes through the cool air duct 12, the ice maker 25, and the cool air duct 14 in order to cool the freezing chamber.

However, in the refrigerator having the ice-maker cooler duct according to the related art, the cool air ducts 12 and 14 are installed on the inner wall on the left side of the freezer compartment so that the thickness of the heat insulation to the left wall of the freezer compartment is reduced, However, since the cold air supplied to the freezing chamber always travels to the freezing chamber after passing through the ice maker 25, the cooling air supply efficiency of the freezing chamber is greatly reduced.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 2 to 6 attached hereto.

A refrigerator having an ice-maker cooler duct according to an embodiment of the present invention includes a refrigerator body 100 divided into a freezer compartment and a refrigerating compartment, a refrigerator door 200 for opening and closing the freezing compartment and the refrigerating compartment of the refrigerator body 100, An ice maker 300 installed on the inner surface of the freezer compartment door 200, an evaporator 400 and a blower fan 500 installed on the rear wall of the refrigerator body 100, 600).

Components of the refrigerator body 100, the refrigerator door 200, the ice maker 300, the evaporator 400, and the blower fan 500 are well known to those skilled in the art.

Hereinafter, the converted cool air duct 600, which is a characteristic component of the present invention, will be described in detail.

The switching cold air duct 600 is installed in the freezer compartment of the refrigerator main body 100 and guides the cold air generated by the evaporator 400 to the ice maker 300 or the freezer compartment do.

To this end, the switching cold air duct 600 is connected in a state where one end in the longitudinal direction is connected to the ice-maker 300 and the other end is in contact with the rear wall of the refrigerator main body 100.

Specifically, the switched cool air duct 600 includes a duct body 610 having a hollow cool air passage 601 formed along the longitudinal direction thereof and having a communication hole 611 communicating with the freezing chamber on one side thereof, A first blocking member 620 installed in the cooling passage 601 of the duct body 610 so as to open and close the cooling passage 611 to interrupt the cool air supplied to the ice maker 300; And a control member 640 for operating the first blocking member 620 and the second blocking member 630. The second blocking member 630 is disposed in the cooling passage 601 of the first blocking member 620,

Since the duct body 610 is linearly installed in the upper part of the inside of the freezer compartment of the refrigerator main body 100, it is possible to omit a complicated manufacturing process in which the heat insulating wall surface of the refrigerator body 100 is reduced or the duct body is buried In addition, since it is not a bent structure as in the conventional art, it is possible to fundamentally block the phenomenon that the flow velocity of cold air is lowered.

In addition, a plurality of communication holes 611 are formed on the bottom surface of the duct body 100 so as to be spaced apart from each other.

That is, the communication hole 611 allows the cool air supplied from the evaporator 400 to be directly supplied to the freezer compartment without passing through the ice maker 300.

In addition, a guide groove 612 is formed in the duct body 610 to smoothly guide the linear movement of the second blocking member 630.

Although not shown in the drawing, a plurality of rollers may be additionally installed in the guide groove 612 along the longitudinal direction of the duct body 100.

The first blocking member 620 is installed at one side of the longitudinal direction of the duct body 610 communicating with the ice maker 300 and controls the flow of cool air supplied from the evaporator 400 toward the ice maker 300 .

The first blocking member 620 is a flat plate corresponding to the cooling air passage 601 of the duct body 610 and is hinged to the side surface of the duct body 610 to rotate.

The second blocking member 630 is a flat plate provided on the bottom surface of the cooling air passage 601 of the duct body 610 and linearly reciprocates along the longitudinal direction of the duct body 610, And serves to open or close the communication hole 611 of the main body 610. [

Of course, the through-hole 631 corresponding to the communication hole 611 is formed in the second blocking member 630.

The operating member 640 is installed on the outer side of the duct body 610 and operates the first blocking member 620 and the second blocking member 630.

In addition, the first blocking member 620, the second blocking member 630, and the operating member 640 may be configured to operate in cooperation with each other.

The operating member 640 is a lever that pivots in the up and down direction to rotate the pinion gear 621.

Accordingly, when the operating member 640 is rotated in one direction, the pinion gear 621 connected to the operating member 640 rotates together. At this time, when the pinion gear 621 rotates, the rack gear 632 engaged with the pinion gear 621 moves in a linear direction by a relative movement.

As a result, when the pinion gear 621 rotates, the first blocking member 620 rotates and the second blocking member 630 slides in a linear direction by the rack gear 632.

6, in order to allow the user to rotate the pinion gear 621 without using the operating member 640, a power supply 640 is provided on the outer side of the duct body 610 facing the operating member 640, And a motor 650 for transmitting the electric power.

As described above, according to the present invention, the cold air generated by the evaporator 400 can be selectively supplied to the ice maker 300 or the freezer compartment, so that the heat insulation wall surface of the refrigerator body 100 is reduced Or the complicated manufacturing process for embedding the duct body 610 can be omitted, and the cold air can be directly transferred to the freezing chamber, if necessary, so that the cooling air supply efficiency of the freezing chamber can be further improved.
