BACKGROUND OF THE INVENTION

1. Field of the Invention

The embodiment relates to a refrigerator.

2. Description of the Related Art

Generally, a refrigerator is an electric home appliance to keep foods in a refrigerated or frozen state. The inside of the refrigerator is provided with a compressor, a condenser, and an expansion unit that forms a freezing cycle and the back surface of the refrigerator body is provided with an evaporator.

Recently, various types of refrigerators have been released onto the market. For example, there are a side by side type where a refrigerating compartment and a freezing compartment are disposed left and right, respectively, a bottom freezer type where a refrigerating compartment is disposed above a freezing compartment, a top mount type where a refrigerating compartment is disposed below a freezing compartment, etc.

In addition, an ice making assembly is disposed inside the refrigerator and the ice making assembly may be disposed in a refrigerating compartment or a freezing compartment or may be a freezing compartment door or a refrigerating compartment door. A product having a dispenser which is capable of drawing out ice made in the ice making assembly and is disposed at the freezing compartment door or the refrigerating compartment door has been released onto the market. Therefore, a user can freely draw out ice without necessarily opening the refrigerator door, thereby making it possible to prevent cold air from being lost.

Meanwhile, a conventional refrigerator has a structure that an evaporator is disposed inside the back surface of the refrigerator body and the cold air generated from the evaporator is supplied to the refrigerating compartment or the freezing compartment through a cold air duct.

Recently, in the case of the side by side type refrigerator, the product in which the evaporator is installed inside a mullion partitioning the refrigerating compartment and the freezing compartment and the cold air flows into the refrigerating compartment and the freezing compartment along the cold air duct formed in the mullion has been released.

SUMMARY OF THE INVENTION

The embodiment is to apply an ice making assembly to a refrigerator having an evaporator disposed in a mullion that partitions a refrigerating compartment and a freezing compartment.

In order to achieve the above object, a refrigerator according to the embodiment includes: a refrigerating compartment; a freezing compartment that is adjacently disposed to the refrigerating compartment; a mullion that partitions the refrigerating compartment and the freezing compartment; a cold air supplying portion that forms a portion of at least mullion and receives an evaporator therein; and

an ice making apparatus that is attached to the cold air supplying portion and makes and stores ice by receiving cold air generated by the evaporator.

With the refrigerator, the evaporator moves from the back surface of the refrigerator to the mullion, thereby increasing the volume of the refrigerator.

In detail, the depth in the front and back direction of the refrigerating compartment or the freezing compartment of the refrigerator is longer and the evaporator is disposed in the mullion so that the increase in the depth of the refrigerating compartment or the freezing compartment is larger than the reduction in the width of the refrigerating compartment or the freezing compartment.

In detail, the evaporator 30 is accommodated in the lower inside of the cold air supplying portion 12, and a cooling fan 31 may be disposed in the upper space of the evaporator 30. A cold air duct extends from the discharge side of the cooling fan 31. In detail, the cold air duct is divided into a first duct 121 at the refrigerating compartment side and a second air duct 124 at the freezing compartment 121 at the discharge side of the cooling fan 31. The first duct 121 is for supplying cold air into the refrigerating compartment and the second duct 124 is for supplying cold air into the freezing compartment. A damper 127 at the freezing compartment side is disposed at an inlet of the second air duct 124 and a damper 128 at the refrigerating compartment side is disposed at the inlet of the first air duct 121, respectively, such that the amounts of the cold air supplied into the refrigerating compartment and the freezing compartment can be controlled.

In addition, cold air suction holes 126 and 123 are disposed at both sides of the cold air supplying portion 12, respectively, that correspond to the lower ends of the evaporator 30. The air inside the freezing compartment 111 and the refrigerating compartment 112 is sucked towards the evaporator 30 through the cold air suction holes 126 and 123.

A water dispensing port 142 that dispenses potable water may be formed on the dispenser 14. A water supply passage L that is connected to a water supply source outside the refrigerator is extended to the inside of the refrigerator 10. More specifically, the water supply passage L may be branched into a water supply passage for ice making L1 and a water supply passage for purifying water L2 at a certain position thereof. The end of the water supply passage for ice making L1 is extended to the ice maker 21 inside the ice compartment 20. The water supply passage for purifying water L2 is extended along the refrigerator main body and is extended to the inside of the refrigerating compartment by penetrating the refrigerator door, in particular, the inside of the hinge for the refrigerating compartment door, thereby being connected to the water dispensing port 142. Although not shown, a filter may be provided rearward (based on the flow direction of water) of the position where the water supply passage for making ice L1 and the water supply passage for purifying water L2 are branched.

More specifically, an inlet of the discharge duct 15 that is formed on the rear surface of the door 13 is closely attached to a bottom portion of the ice compartment 20, and an outlet thereof is connected to the dispenser 14. Therefore, a damper 151 formed inside the discharge duct 15 is operated by pressing a button 141 formed on the dispenser 14 and thus an internal path of the discharge duct 15 is opened, such that the ice is discharged to the dispenser 14.

Further, the ice compartment 20 forms an ice chamber therein by a insulation wall 23, wherein the ice maker 21, the ice bin 22 that stores ice, and the ice compartment fan 25 are provided inside the insulation wall 23. Also, ice outlets are formed in the ice bin 22 and the bottom surface of the insulation wall 23, respectively, and the ice outlets are configured to communicate with the inlet of the discharge duct 15.

More specifically, the insulation wall 23 is configured of an upper insulation wall 231, a lower insulation wall 233, a pair of side insulation walls 232, a frontal insulation wall 235, and a rear insulation wall 234. A plurality of cold air inlet holes 236 are formed on the insulation wall that is closely adhered to the cold air supplying portion 12, among the pair of side insulation walls 232. Then, the cold air inlets 236 are configured to communicate with the cold air outlets 122 of the first duct 121. A plurality of cold air outlets 237 are formed on the lower side of the cold air inlets 236. One or more cold air outlets 237 are configured to communicate with the return duct 129 inside the mullion 113. The edges of the cold air inlet 236 and the cold air outlet 237 are respectively formed with a sealing member 238, such that when the ice compartment is disposed in the mullion 113, it prevents the leakage of cold air. The ice maker 21 and the ice bin 22 are surrounded by the insulation wall 23, such that the heat exchange with the air of inside the refrigerating compartment is blocked. Therefore, the problem that the temperature in the ice compartment 20 is increased, whereby the ice within the ice compartment 120 is melted or the ice making is not properly performed may be prevented.

In addition, the frontal insulation wall 235 forming the insulation wall 23 is integrally coupled with the front surface of the ice bin 22, such that it can be drawn out together with the ice bin 22. In other words, only the frontal insulation wall 235 is disposed to be separated from other insulation walls and is connected to the ice bin 22, such that the user can separate the ice bin 22 from the ice compartment 20.
