Abstract

A refrigerator according to an embodiment of the present disclosure includes a cabinet forming a storage space; an evaporator located at a rear of the storage space and forming cold air; and a grill pan assembly located at the rear of the storage space, in which the grill pan assembly includes a grill pan, and a blowing fan assembly disposed at a rear of the grill pan and configured to supply the cold air to the storage space, and the blowing fan assembly includes a first flow path through which the cold air moves in a direction away from the evaporator, and a second flow path through which the cold air moves in a direction closer to the evaporator.

First claim

What is claimed is:

1 . A refrigerator comprising:
a cabinet forming a storage space; an evaporator located at a rear of the storage space and forming cold air; and a grill pan assembly located at the rear of the storage space, wherein the grill pan assembly includes: a grill pan, and a blowing fan assembly disposed at a rear of the grill pan and configured to supply cold air to the storage space, and wherein the blowing fan assembly includes: a first flow path through which the cold air moves in a direction away from the evaporator, and a second flow path through which the cold air moves in a direction closer to the evaporator.

2 . The refrigerator of claim 1 ,
wherein the blowing fan assembly includes a blowing fan configured to flow cold air, and wherein the blowing fan is located between the first flow path and the second flow path.

3 . The refrigerator of claim 2 ,
wherein the blowing fan is configured to inhale the cold air from the front and discharge the cold air in a radial direction.

4 . The refrigerator of claim 2 ,
wherein the evaporator is located below the blowing fan assembly.

5 . The refrigerator of claim 2 ,
wherein the grill pan assembly further includes an insulation member disposed at the rear of the grill pan and forming a flow path through which the cold air flows, and wherein the insulation member is disposed not to overlap the blowing fan in the front and rear direction.

6 . The refrigerator of claim 1 ,
wherein the grill pan includes: a first plate part formed with a first pan discharge port through which the cold air provided from the first flow path is discharged, and a second plate part formed with a second pan discharge port through which the cold air provided from the second flow path is discharged and located at a front of the first plate part, and wherein the second pan discharge port is located lower than the first pan discharge port.

7 . The refrigerator of claim 6 ,
wherein the blowing fan assembly includes a blowing fan disposed between the first flow path and the second flow path and configured to flow the cold air, and wherein the second pan discharge port is located lower than the blowing fan.

8 . The refrigerator of claim 6 ,
wherein the second plate part is located at the front of the first plate part.

9 . The refrigerator of claim 8 ,
wherein the grill pan assembly further includes an insulation member disposed at the rear of the grill pan and forming a flow path through which the cold air flows, wherein the grill pan further includes a third plate part connecting the first plate part and the second plate part, and wherein the insulation member is disposed to overlap the first plate part and the second plate part in the front and rear direction, but not to overlap the third plate part in the front and rear direction.

10 . The refrigerator of claim 6 ,
wherein the evaporator is located at a rear of the second plate part, and wherein the second pan discharge port is located above the evaporator.

11 . The refrigerator of claim 6 ,
wherein the blowing fan assembly includes a blowing fan configured to flow the cold air, and wherein the blowing fan is located between the first plate part and the second plate part.

12 . The refrigerator of claim 1 ,
wherein the storage space includes: a first storage part provided with the cold air moving through the first flow path, and a second storage part provided with the cold air moving through the second flow path, and wherein the second storage part is maintained at a lower temperature than the first storage part.

13 . A refrigerator comprising:
a cabinet forming a storage space; an evaporator located at a rear of the storage space and forming cold air; and a grill pan assembly installed at the rear of the storage space, wherein the grill pan assembly includes: a grill pan, and a blowing fan assembly disposed at a rear of the grill pan and configured to supply the cold air to the storage space, wherein the blowing fan assembly includes: a blowing fan, and a blowing fan cover configured to accommodate the blowing fan, and wherein the blowing fan cover includes: a cover main body including an upper opening opened upward and defining an accommodation space in which the blowing fan is provided, and a cover extension part protruding forward from the cover main body and includes a front opening that opens forward.

14 . The refrigerator of claim 13 ,
wherein the upper opening is disposed on one side of the blowing fan, and wherein the cover extension part is disposed on the other side of the blowing fan.

15 . The refrigerator of claim 13 ,
wherein the cover extension part extends in a downwardly inclined direction toward the front.

16 . The refrigerator of claim 13 ,
wherein the front opening is disposed below the blowing fan.

17 . The refrigerator of claim 13 ,
wherein the storage space includes: a first storage part, and a second storage part maintained at a lower temperature than the first storage part, and wherein the front opening is connected to the second storage part.

18 . The refrigerator of claim 13 ,
wherein the grill pan includes: a first plate part located above the blowing fan and having a first pan discharge port through which the cold air provided from the upper opening is discharged, a second plate part located lower than the blowing fan, having a second pan discharge port through which the cold air provided from the front opening is discharged, and located forward of the first plate part, and a third plate part connecting the first plate part and the second plate part.

19 . The refrigerator of claim 18 ,
wherein the grill pan assembly further includes an insulation member disposed at the rear of the grill pan and forming a flow path through which the cold air flows, and wherein the insulation member is disposed to overlap the first plate part and the second plate part in the front and rear direction, but not to overlap the third plate part in the front and rear direction.

20 . The refrigerator of claim 18 ,
wherein the evaporator is located at a rear of the second plate part, and wherein the second pan discharge port is located above the evaporator.
