## Abstract

An ice-making device in a refrigerator including water blocking walls configured to prevent water supplied to an ice tray from straying outside the ice tray. The ice-making device includes an upper frame and a lower frame. A water supply port is disposed in a rear wall of the upper frame and configured to supply water to an ice tray between the upper frame and the lower frame. An upper sidewall protrudes downward from the upper frame. A main water-blocking rib protrudes from the rear wall and configured to prevent water supplied from the water supply port from straying along the upper sidewall. An auxiliary water-blocking rib protrudes from the upper sidewall and can further prevent the water supplied from the water supply port from straying along the upper sidewall.

## Claims

### Claim 1

An ice-making device for a refrigerator, the ice-making device comprising:
an upper frame;
a lower frame coupled to the upper frame at a lower side thereof;
an ice tray disposed between the upper frame and the lower frame;
a water supply port formed in a rear wall of the upper frame and configured to supply water to the ice tray, the water supply port being opened in a lengthwise direction of the ice tray;
an upper sidewall protruding downward from an edge of an upper surface of the upper frame; and
a first water-blocking rib protruding from the rear wall along the lengthwise direction of the ice tray,
wherein an end of the first water-blocking rib protrudes beyond an end of the water supply port along the lengthwise direction of the ice tray.

### Claim 2 (depends on 1)

The ice-making device of claim 1, wherein the first water-blocking rib is configured to prevent the water supplied from the water supply port from straying along the upper wall.

### Claim 3 (depends on 1)

The ice-making device of claim 1, further comprising a second water-blocking rib protruding from the upper sidewall.

### Claim 4 (depends on 3)

The ice-making device of claim 3, wherein the second water-blocking rib is configured to prevent the water supplied from the water supply port from straying along the upper sidewall.

### Claim 5 (depends on 1)

The ice-making device of claim 1, wherein the water supply port is disposed at an opposite side with respect to a centerline of the ice tray to a side at which ice pieces are released.

### Claim 6 (depends on 3)

The ice-making device of claim 3, wherein the ice tray comprises partition ribs and wherein ice cells are partitioned by the partition ribs, and wherein a distance between the first water-blocking rib and the second water-blocking rib equals to a width of an ice cell of the ice tray.

### Claim 7 (depends on 1)

The ice-making device of claim 1, further comprising an ice-storing unit configured to store ice pieces produced in the ice tray.

### Claim 8

An ice-making device for a refrigerator, the ice-making device comprising:
an upper frame;
a lower frame coupled to the upper frame at a lower side thereof;
an ice tray disposed between the upper frame and the lower frame;
a water supply port disposed in a rear wall of the upper frame and configured to supply water to the ice tray, the water supply port being opened in a lengthwise direction of the ice tray;
a water-blocking rib formed to protrude from the rear wall; and
an upper side wall extending downward from an opposite edge of an upper surface of the upper frame, wherein ice pieces are released at a location proximate to the upper side wall, wherein the upper side wall is disposed outside a sidewall of the ice tray and operable to prevent water supplied from the water supply port from straying along the sidewall of the ice tray,
wherein an end of the first water-blocking rib protrudes beyond an end of the water supply port along the lengthwise direction of the ice tray.

### Claim 9

A refrigerator comprising:
a first body enclosing storage spaces; and
an ice-making device comprising:
an upper frame;
a lower frame coupled to the upper frame at a lower side thereof;
an ice tray disposed in an internal space between the upper frame and the lower frame;
a water supply port formed in a rear wall of the upper frame and configured to supply water to the ice tray, the water supply port being opened in a lengthwise direction of the ice tray;
an upper sidewall protruding downward from an edge of an upper surface of the upper frame; and
a first water-blocking rib protruding from the rear wall along the length direction of the ice tray,
wherein an end of the first water-blocking rib protrudes beyond an end of the water supply port along the lengthwise direction of the ice tray.

### Claim 10 (depends on 9)

The refrigerator of claim 9, wherein the first water-blocking rib is configured to prevent water supplied from the water supply port from straying outside the ice tray.

### Claim 11 (depends on 10)

The refrigerator of claim 10, wherein the ice-making device further comprises a second water-blocking rib protruding from the upper sidewall.

### Claim 12 (depends on 11)

The refrigerator of claim 11, wherein the second water-blocking rib is configured to further prevent water supplied from the water supply port from straying outside the ice tray.

### Claim 13 (depends on 9)

The refrigerator of claim 9, wherein the water supply port is disposed at an opposite side with respect to a centerline of the ice tray to a side at which ice pieces are released.

### Claim 14 (depends on 12)

The refrigerator of claim 12, wherein the ice tray comprises partition ribs, wherein the ice cells are partitioned by the partition ribs, and wherein a distance between the first water-blocking rib and the second water-blocking rib equals to a width of an ice cells in the ice tray.

### Claim 15 (depends on 9)

The refrigerator of claim 9, wherein the ice-making device further comprises an ice-storing unit configured to store ice pieces produced in the ice tray.
