Hereinafter, the connection duct 300 will be described in detail.

5 is a plan view of the inner box of the freezer compartment refrigerating compartment and the connection duct according to an embodiment of the present invention, FIG. 6 is a view showing the inner box of the freezer compartment refrigerating compartment according to an embodiment of the present invention from the rear, and FIG. 7 is a view of the present invention It is a view showing the inner box of the refrigerating compartment of the freezer compartment according to an embodiment from the rear in a direction different from that of FIG. 6 .

As shown in FIGS. 5 to 7 , the refrigerator 1 is disposed between the freezing compartment duct 200 and the refrigerating compartment duct 100 , and the cold air inside the freezing compartment duct 200 flows into the refrigerating compartment duct 100 in the freezing compartment. A connection duct 300 connecting the duct 200 and the refrigerating compartment duct 100 may be included.

One end 301 of the connection duct 300 is connected to the first hole 250 of the freezing chamber duct 200 through which cold air in the freezing chamber duct 200 flows out, and the other end 302 of the connection duct 300 is the freezing chamber duct ( It may be connected to the second hole 150 of the refrigerating compartment duct 100 connected to the connection duct 300 so that cold air is introduced from the 200 .

The first hole 250 may be formed in the side surface 200a of the freezing compartment duct 200 . The second hole 150 may be formed in the side surface 100a of the refrigerating compartment duct 100 facing the side surface 200a of the freezing compartment duct 200 .

As described above, the side surface 200a of the freezing compartment duct 200 is formed by a portion of the side surface 41c of the freezing compartment inner box 41. In other words, the first hole 250 is the side surface of the freezing compartment inner box 41. (41c) may be formed.

As described above, the side surface 100a of the refrigerating compartment duct 100 is formed by a portion of the side surface 42c of the refrigerating compartment inner box 42 . In other words, the second hole 150 is the side surface of the refrigerating compartment inner box 42 . (42c) may be formed.

The side surface 200a of the freezing compartment duct 200 and the side surface 100a of the refrigerating compartment duct 100 may be disposed to face each other in the left and right direction Y, respectively. That is, the side surface 200a of the freezer compartment duct 200 and the side surface 100a of the refrigerating compartment duct 100 are respectively arranged side by side in the left-right direction (Y) of the freezer compartment inner box 41 and the refrigerating compartment inner box 42, respectively, in the left-right direction. (Y) can be arranged side by side.

Accordingly, the first hole 250 and the second hole 150 may be provided to be opened in directions facing each other, respectively. That is, the first hole 250 and the second hole 150 may be arranged side by side in the left and right direction.

However, the present invention is not limited thereto, and the first hole 250 and the second hole 150 may be disposed so as to have an inclination at an angle within approximately 90 degrees "direction?* in which the first and second holes 250 and 150 are opened, respectively. can

Accordingly, the connection duct 300 may be provided to extend in the left-right direction (Y). In detail, one end 301 of the connection duct 300 may be disposed on one side in the left-right direction (Y) and the other end 302 may be disposed on the other side opposite to one side in the left-right direction (Y).

As the connection duct 300 extends in the left-right direction (Y), the cold air flowing out from the freezing compartment duct 200 may flow in the left-right direction (Y) along the connection duct 300 and may be introduced into the refrigerator compartment duct 100. .

The freezing compartment duct 200 and the refrigerating compartment duct 100 are disposed adjacent to each other in the left-right direction (Y), and as the connection duct 300 extends in the left-right direction (Y), cold air flowing out from the freezing compartment duct 200 is a connection duct The path flowing along the 300 is minimized, so that the cooling efficiency of the refrigerating compartment duct 100 may be increased.

The rear surface 300a of the connection duct 300 in the front-rear direction X may be disposed in front of the rear surface 100b of the refrigerating compartment duct 100 or the rear surface 42a of the refrigerating compartment inner box 42 .

This is because the connecting duct 300 extends in the left-right direction (Y), so that a part of the connecting duct 300 extends to the rear of the rear surface 100b of the refrigerating compartment duct 100 or the rear surface 42a of the refrigerating compartment inner box 42. because there is no need

Accordingly, the rear surface 42a of the refrigerating compartment inner box 42 may be configured to be disposed closest to the inner side of the main body 10 in the front-rear direction (X), and accordingly, the inner surface of the main body 10 and the refrigerating compartment inner box 42 ) between the rear surface 42a of the refrigerator compartment 22, the capacity of the refrigerator compartment 22 can be increased by maintaining only the minimum distance for insulation and placing the rear surface 42a of the inner box 42 of the refrigerating compartment as close as possible to the inner side of the main body 10. can

In addition, the cold air of the freezing compartment duct 200 can be efficiently introduced into the cold air of the refrigerating compartment duct 100 by the connection duct 300 , so that the evaporator E does not need to be additionally disposed on the refrigerating compartment duct 100 side.

Accordingly, the thickness of the refrigerating compartment duct 100 in the front-rear direction (X) can be minimized, and accordingly, the capacity of the refrigerating compartment 22 can be increased to increase the efficiency of the refrigerating compartment 1 . In the cooling space 45 , The cooled air is introduced into the freezing compartment duct 200 by the blowing fan 260, and a part of the cold air introduced into the freezing compartment duct 200 is discharged into the freezing chamber through the outlets 220, 230, 240 of the freezing compartment duct 200. The other portion may be introduced into the refrigerating compartment duct 100 through the connection duct 300 .

The refrigerator 1 may include a damper 400 that selectively opens and closes the connection duct 300 . (refer to Fig. 9)

As described above, the cold air formed in the cooling space 45 maintains a temperature of about -20 degrees, but the refrigerating compartment 22 needs to maintain a temperature of about 0 degrees or more. Therefore, when the internal temperature of the refrigerating compartment 22 is maintained at approximately 0 degrees, the connecting duct 300 is selectively provided at one end 301 of the connecting duct 300 to prevent additional low-temperature cold air from flowing into the refrigerating compartment 22 . A damper 400 that opens and closes may be provided.

In the conventional case, the damper was disposed on the side of the refrigerating compartment. Specifically, the damper was disposed inside the refrigerating compartment duct, and the connector of the refrigerating compartment duct was selectively opened and closed so that the other end of the connecting duct selectively communicated with the refrigerating compartment duct.

Accordingly, the volume of the refrigerating compartment duct increases, and in particular, the refrigerating compartment duct protrudes forward as much as the space where the damper is disposed.

In order to solve this problem, the damper 400 of the refrigerator 1 according to an embodiment of the present invention is disposed inside the freezing compartment duct 200 to secure a wider space in the refrigerating compartment 22 .

The freezing compartment duct plate 210 may be disposed in front of at least a portion of the refrigerating compartment duct plate 110 . This is because the cooling space 45 in which the evaporator E is disposed is formed between the rear surface of the main body 10 and the freezing chamber 21 .

That is, the length of the front-rear direction (X) of the freezing compartment 21 may be formed shorter than the length of the front-rear direction (X) of the refrigerating compartment 22, and accordingly, the freezing compartment duct plate 210 is the refrigerating compartment duct plate 110. It may be disposed in front of at least a portion of the.

As the freezer compartment duct plate 210 is disposed in front of the refrigerating compartment duct plate 110, the inner space 203 of the freezing compartment duct 200 is formed wider in the front-rear direction (X) than the inner space of the refrigerating compartment duct 100. can

Accordingly, when the damper 400 is formed in the inner space 203 of the freezing compartment duct 200 , the capacity loss of the freezing compartment 21 and the refrigerating compartment 22 may not occur.

Hereinafter, the damper 400 will be described in detail.

8 is a view showing the rear of the freezing compartment duct in a state in which the duct cover is removed from the freezing compartment duct according to an embodiment of the present invention, and FIG. 9 is a view showing a state in which the damper frame is removed in FIG.

8 and 9 , the damper 400 may be disposed inside the freezing compartment duct 200 .

The duct cover 270 of the freezing compartment duct 200 may include an inlet 271 that is opened to introduce air into the blowing fan 260 .

The duct cover 270 may include a damper housing 272 extending to the rear of the duct cover 270 to cover the damper 400 and having a shape substantially similar to the appearance of the damper 400 .

The damper housing 272 may be formed as a part of the duct cover 270 . The damper housing 272 and the duct cover 270 may be integrally formed. However, the present invention is not limited thereto, and the damper housing 272 and the duct cover 270 may be provided to be coupled to each other in separate configurations.

An opening communicating with the first hole 250 formed in the side surface 200a of the above-described freezing compartment duct 200 may be formed on a side surface of the damper housing 272 . The damper 400 disposed inside the damper housing 272 selectively restricts the flow of the cold air flowing in the freezing compartment duct 200 to the connection duct 300 by selectively opening and closing the first hole 250 to the refrigerating compartment. It is possible to selectively limit the provision of cold air to the duct 100 .

The damper 400 includes a door 420 selectively opening and closing the first hole 250 or one end 301 of the connection duct 300, a door frame 410 to which the door 420 is rotatably coupled, and the door. A driving unit 430 for driving the 420 may be included.

The door 420 may be rotated about the rotation axis R. The door 420 may open the first hole 250 while rotating in a direction opposite to the connection duct 300 or in a direction in which the blowing fan 260 is disposed about the rotation axis R.

That is, the opening rotation direction of the door 420 is the central direction of the refrigerating duct 200 .

Also, the door 420 may close the first hole 250 while rotating in the direction of the connection duct 300 about the rotation axis R. That is, the closing rotation direction of the door 420 is the direction in which the refrigerating compartment duct 100 is disposed. This is to drain the condensed water that is frozen between the door 420 and the door frame 410 .

The driving unit 430 may rotate the door 420 by being connected to the door 420 in the direction of the rotation axis R of the door 420 .

Unlike the refrigerating compartment duct 100 , cold air of about -20 degrees is introduced into the freezing compartment duct 200 . Accordingly, water vapor in the air flowing inside the refrigerator 1 collides with the damper 400 , thereby generating condensate. The condensed water collided with the 400 may be frozen inside the duct 400 by the low temperature formed inside the freezing chamber duct 200 .

In particular, when the condensed water is frozen between the door 420 and the door frame 410 , rotation of the door 420 is restricted and the damper 400 may be induced to malfunction.

Accordingly, the damper 400 according to an embodiment of the present invention may be disposed to be inclined with respect to the vertical direction Z so that, when condensed water is generated inside the damper 400 , the condensed water is easily drained.

In detail, the damper 400 may be disposed to be inclined at a predetermined angle θ1 in the left-right direction (Y) orthogonal to the vertical direction (Z).

In particular, in the door frame 410, one surface of the door frame 410 disposed adjacent to the blower fan 260 has a predetermined angle θ1 in the left and right direction Y perpendicular to the vertical direction Z. It may be inclinedly disposed. This is because, in the damper 400 , one surface of the door frame 410 facing the blowing fan 260 is the region in which the most collision with the circulating air occurs.

The condensed water formed on one surface of the door frame 410 is inclined in the vertical direction (Z) and left and right directions (Y) along the slope as the damper 400 is inclined in the left and right direction (Y) orthogonal to the vertical direction (Z). It can flow to the bottom of the bed.

Also, although not shown in the drawing, the damper 400 may be additionally disposed to be inclined at a predetermined angle in the front-rear direction (X) orthogonal to the vertical direction (Z).

Condensed water colliding with one surface of the door frame 410 and the door 420 may flow to the lower end of the door frame 410 by an inclination in the front-rear direction X orthogonal to the vertical direction Z.

That is, the damper 400 may be disposed to be inclined with respect to 3-dimension. Accordingly, in detail inside the damper 400, when condensed water occurs on the door 420 or the door frame 410, it drains easily along the slope toward the lowermost end in the front-rear direction (X) and left-right direction (Y) of the damper 400 can be

As described above, the evaporator E may be disposed below the freezing chamber duct 200 (see FIG. 3). Accordingly, the condensed water dripping along the damper 400 reaches the surface of the evaporator E, and the evaporator (E) E) can freeze in phase.

The condensed water frozen on the evaporator (E) may be defrosted by heat generated in the evaporator (E) during the defrosting process of the refrigerator (1).

As such, condensed water generated inside the damper 400 may easily freeze due to the low temperature inside the freezing compartment duct 200, but the damper 400 is disposed inclinedly, and accordingly, when condensed water occurs, the damper 400 and the freezer compartment Since the duct 200 can be easily drained to the outside, the damper 400 can be stably driven.
