The present invention relates to an ice making device of a refrigerator, and more particularly, to an ice making channel structure of a side-by-side type refrigerator having an ice making device installed in a freezer door and providing a cold air supply flow path to the ice making device. It is about.

In general, the refrigerator is one of the necessities of life as a device that keeps the food fresh or freezes for a certain period of time by lowering the inside of the refrigerator as the refrigerant cycles compression, condensation, expansion and evaporation. .

Currently, refrigerators are becoming larger and larger, and many types of refrigerators, such as side-by-side type refrigerators, are being developed to meet user needs.

In the case of such a double door type refrigerator, it is divided into a freezer compartment and a refrigerating compartment, and in addition to a simple freezing and refrigerating function, an ice maker for deicing the supply water and extracting and storing the water is applied as an additional function.

Hereinafter, an ice making apparatus of a conventional side by side type refrigerator will be described with reference to FIGS. 1 to 5.

1 to 2 illustrate a structure of an ice making apparatus installed in a general side-by-side type refrigerator. Referring first to FIGS. 1 and 2, the side-by-side type refrigerator 100 includes a freezer compartment 1 and a refrigerating compartment ( 2), doors 3 and 4 are installed to open and close the freezer compartment 1 and the refrigerating compartment 2. An ice maker 50 as illustrated in FIG. 3 is installed inside the freezer compartment door 3, and a control panel 6 is installed on an outer surface of the freezer compartment door 3 so that a user can select a predetermined function of the refrigerator. .

The ice making device 50 is installed inside the freezer compartment door 3, and is composed of an ice maker 10 for producing ice and an ice bank 20 for storing the produced ice. An ice transfer device (not shown) for discharging the ice of the ice bank 20 to the outside and a dispenser 7 are installed to directly obtain the ice.

3 to 5, the ice maker 10 includes an ice making chamber 11 in which ice is generated and a water supply for supplying water to the ice making chamber 11 formed at one side of the ice making chamber 11. The part 12 is formed.

The ice-making chamber 11 has a substantially semi-cylindrical shape, and partition ribs 11a are formed to protrude upward at predetermined intervals so that ice can be separated therein. In addition, a fastening part 15 is formed at a rear predetermined portion of the ice making chamber 11 to fix the ice making device 50 to the freezing chamber.

The motor unit 13 is installed at one side of the ice making chamber 11. The motor unit 13 has a built-in motor, the ejector 14 (ejector) is rotatably connected to the rotating shaft of the motor.

The ejector 14 is installed such that the rotating shaft crosses the center of the ice making chamber 11, and a plurality of ejector pins 14a are spaced at predetermined intervals so that the rotating shaft of the ejector 14 is substantially perpendicular to the rotating shaft. do. At this time, each of the ejector pin 14a is disposed for each section partitioned by the partition ribs 11a.

A plurality of slide bars 16 extend in the upper end of the front side of the ice making chamber 11 to about the rotation axis of the ejector 14.

In addition, a heater 17 (see FIG. 5) is attached to the bottom surface of the ice making chamber 11. The heater 17 heats the surface of the ice making chamber for a short time to slightly dissolve the ice surface attached to the surface of the ice making chamber so that the ice can be easily separated from the ice making chamber 11.

The ice maker 10 is provided with an ice-covering arm 18 to measure the amount of ice filled in the ice bank 20. The ice detection arm 18 is installed to be movable up and down and is connected to a control unit embedded in the motor unit 13. By the action of the ice detection arm 18 and the control unit, the ice bank 20 is filled with a certain amount of ice.

The ice bank 20 has an upper surface open to receive falling ice and an ice outlet 21 is formed in a predetermined portion of the bottom surface. The ice outlet 21 is formed at one end of the ice feeder.

In addition, the ice bank 20 is provided with an ice transfer means 22, a motor device 23, an ice crusher 30 and an ice discharger (40).

The ice conveying means 22 is formed in a thread form and is installed to cross the inside of the ice bank 20. The ice transfer means 22 is rotatably coupled to the motor device 23.

Accordingly, when the motor device 23 is rotated, the ice is moved to the ice grinder 30 as the ice transfer means 22 is rotated.

Referring to the operation of the icemaker of the conventional refrigerator configured as described above are as follows.

When the ice bank 20 determines that the ice bank 20 lacks ice, the water is supplied to the water supply unit 12 of the ice maker 10. This water is filled up to a predetermined level in the ice making chamber 11 and is frozen by cold air in the freezing chamber. At this time, the partition rib 11a of the ice making chamber 11 serves to divide the ice produced in the ice making chamber 11 into a predetermined size.

When ice is produced in this way, the heater 17 of the ice making apparatus is operated for a short time to melt the contact surface of the ice in contact with the surface of the ice making chamber 11. Subsequently, as the ejector pin 14a is rotated by the motor unit 13, each ice positioned in the corresponding space is discharged to the outside. This ice is discharged to the ice bank 20 as shown in FIG.

If the ice bank 20 is filled with a predetermined amount of ice by repeating this series of processes, the ice making process of the ice maker 10 is terminated by the control unit. In addition, if it is determined that the ice is insufficient in the ice detection arm 18, the ice making process is performed again, so that the ice maker 10 is filled with a predetermined amount of ice.

In this state in which the ice bank 20 is filled with ice, when the user selects a predetermined button of the control panel, uncrushed ice (hereinafter referred to as ice cube) or crushed ice is discharged to the dispenser 7.

Accordingly, users can selectively obtain ice cubes and crushed ice.
