The refrigerator also has a cooling system consisting of a compressor, a condenser and an evaporator to supply cold air to the freezer compartment and the refrigerating compartment. The compressor receives power from an external power source to compress the refrigerant, and the refrigerant compressed in the compressor is condensed in the condenser, and the evaporator generates cold air by evaporating the refrigerant condensed in the condenser. The cold air produced in the evaporator is supplied to the freezer compartment and the refrigerating compartment by a blower fan.
도 1과 도 2에 도시된 바와 같이, 종래 냉장고의 냉동실(181)은 저장품을 수납 저장하는 복수의 선반에 의하여 구획되어 있다. 냉동실(181) 후방영역에는 상하방향을 따라 냉동실(181)의 후벽으로부터 소정의 이격공간이 형성되도록 냉동실덕트부재(110)가 마련되어 있다. 냉동실덕트부재(110)는 냉동실(181)의 후벽으로부터 전방측으로 소정의 이격공간을 두고 배치된 덕트후면판(111)과, 덕트후면판(111)으로부터 소정의 이격공간을 두고 배치되며 판면을 관통하여 복수의 냉기토출구가 형성된 덕트전면판(112)을 갖는다. 냉동실덕트부재(110)의 덕트전면판(112) 및 덕트후면판(111)은 후술할 증발기(120)로부터 냉기를 냉동실로 안내하는 냉기유로를 형성한다.1 and 2, the freezer compartment 181 of the conventional refrigerator is partitioned by a plurality of shelves for storing and storing the storage items. The freezing chamber duct member 110 is provided in the rear region of the freezing chamber 181 so that a predetermined space is formed from the rear wall of the freezing chamber 181 along the vertical direction. The freezing chamber duct member 110 is arranged with a predetermined spaced apart space from the rear wall of the freezing chamber 181 with a predetermined space from the rear wall of the freezing chamber 181 and a predetermined spaced space from the ducted back plate 111 and penetrates the plate surface. The duct face plate 112 is formed with a plurality of cold air discharge port. The duct front plate 112 and the duct back plate 111 of the freezing chamber duct member 110 form a cold air flow path for guiding cold air from the evaporator 120 to be described later.
덕트후면판(111)의 배면하부영역에는 응축기(미도시)에서 응축된 냉매를 증발시켜 냉기를 생성하는 증발기(120)가 마련되어 있다. 증발기(120)의 상부에는 증발기(120)에서 생성된 냉기를 냉동실(181) 및 냉장실(182)로 공급하는 송풍팬(130)이 마련되어 있다. 증발기(120) 하부영역에는 덕트후면판(111)을 경계면으로 하여 냉동실(181)을 순환한 냉기를 증발기(120)로 안내하는 냉동실 냉기귀환덕트(140)가 형성되어 있다.An evaporator 120 is formed in the bottom lower region of the duct rear plate 111 to generate cold air by evaporating the refrigerant condensed in a condenser (not shown). An upper part of the evaporator 120 is provided with a blowing fan 130 for supplying the cold air generated by the evaporator 120 to the freezing chamber 181 and the refrigerating chamber 182. In the lower region of the evaporator 120, a freezer compartment cold air return duct 140 is formed to guide the cold air circulated through the freezer compartment 181 to the evaporator 120 using the duct rear plate 111 as an interface.
그리고 냉동실(181) 및 냉장실(182)의 후벽 후방영역에는 냉장실(182)을 순환한 냉기를 증발기(120)로 안내하는 냉장실 냉기귀환덕트(150)와, 증발기(120)에서 생성된 냉기를 냉장실로 안내하는 냉장실 냉기송출덕트(160)가 마련되어 있다. In the rear wall rear regions of the freezer compartment 181 and the refrigerating chamber 182, the refrigerating chamber cold air return duct 150 for guiding the cold air circulated in the refrigerating chamber 182 to the evaporator 120 and the cold air generated in the evaporator 120 are the refrigerating chamber. Refrigerating chamber cold air duct 160 to guide to the is provided.
이러한 구성에 의하여, 증발기(120)에서 생성된 냉기는 송풍팬(130)에 의해 냉동실덕트부재(110)에 형성된 냉기유로로 송풍된 후, 일부 냉기는 냉동실덕트부재(110)의 덕트전면판(112)에 형성된 냉기토출구(191)를 통해 냉동실(181) 내부로 안내되고, 또 다른 일부의 냉기는 냉장실 냉기송출덕트(160)에 의해 냉장실(182) 내부로 안내되어 각각 고내를 순환한 후에, 냉동실(181)의 냉기는 냉동실 냉기귀환덕트(140)에 의해서 다시 증발기(120)로 귀환하고, 냉장실의 냉기는 냉장실 냉기귀환덕트(150)에 의해서 다시 증발기(120)로 귀환하는 순환과정을 반복하게 된다. By such a configuration, after the cold air generated in the evaporator 120 is blown into the cold air flow path formed in the freezing chamber duct member 110 by the blower fan 130, some cold air is formed on the duct face plate of the freezing chamber duct member 110. After the cold air discharge port 191 formed in the 112 is guided into the freezer compartment 181, and another part of the cold air is guided into the refrigerating compartment 182 by the refrigerating compartment cold air delivery duct 160, respectively, after circulating the inside of the refrigerator, The cold air of the freezer compartment 181 is returned to the evaporator 120 again by the freezer cold air return duct 140, and the cold air of the freezer compartment is repeated by the cold compartment return air duct 150 to the evaporator 120 again.

이러한 종래의 냉장고에 있어서, 냉장실(182)을 순환한 고온다습한 상태의 공기가 냉장실 냉기귀환덕트(150)에 의해서 증발기(120)로 안내되므로 상대적으로 온도가 낮은 냉동실(181)의 공기와 만나게 되어, 증발기(120)에 성에가 발생하게 된다. In such a conventional refrigerator, air in a high temperature and high humidity state circulating in the refrigerating compartment 182 is guided to the evaporator 120 by the refrigerating compartment cold air return duct 150 to meet the air of the freezing compartment 181 having a relatively low temperature. Thus, frost is generated in the evaporator 120.
증발기(120)의 성에발생의 양이 증가하여 쌓이게 되면 증발기의 열전달이 원활히 이루어지지 못하여 증발기의 효율이 낮아지고, 냉장고내의 공기의 흐름이 원할하지 못하여 송풍팬에 과부하가 발생하여 유동효율도 낮아지게 된다. If the amount of frost generated in the evaporator 120 increases and accumulates, the heat transfer of the evaporator may not be performed smoothly, and the efficiency of the evaporator may be lowered, and the flow of air in the refrigerator may not be desired. do.
따라서 본 발명의 목적은, 증발기에 발생하는 성에의 양을 줄일 수 있는 냉장고를 제공하는 것이다. It is therefore an object of the present invention to provide a refrigerator which can reduce the amount of frost generated in the evaporator.

The cold air distribution plate 72 of the cold air distribution member 70 forms a cold air flow path that guides the cold air from the evaporator 20 to the refrigerating chamber 92.
그리고 냉장실(92)의 후벽 및 냉동실(91)의 후벽 후방영역에는 냉장실(92)을 순환한 냉기를 증발기(20)로 안내하는 냉장실 냉기귀환덕트(50)가 마련되어 있으며, 증발기(20)에서 생성된 냉기를 냉장실(92)로 안내하는 냉장실 냉기송출덕트(60)가 마련되어 있다.
