본 발명은 냉장고에 관한 것으로, 더욱 상세하게는 냉장실 내부로 냉기가 보다 골고루 공급될 수 있게 하는 동시에 냉장실의 내부용적이 커질 수 있도록 냉기순환구조를 개선한 냉장고에 관한 것이다.The present invention relates to a refrigerator. More particularly, the present invention relates to a refrigerator having an improved cold air circulation structure so that cold air can be more evenly supplied into a refrigerator compartment, and an internal volume of the refrigerator compartment can be increased.

일반적으로 냉장고는 내부에 냉동사이클의 구성요소가 설치되어 이로부터 발생되는 냉기를 저장실로 공급하여 각종 식품의 신선도를 장기간 유지할 수 있도록 한 가전제품이다.In general, the refrigerator is a home appliance that is installed inside the refrigeration cycle to supply the cold air generated therein to the storage compartment to maintain the freshness of various foods for a long time.

이러한 냉장고는 도 1에 도시된 바와 같이, 본체(10)의 내부에 상측으로 냉동실(11)이 형성되고, 하측으로 냉장실(12)이 마련되는데, 냉동실(11)과 냉장실(12)의 전면에는 이들을 개폐하는 도어(13,14)가 설치된다. 그리고 냉동실(11)과 냉장실(12)의 내측 후벽에는 각각 냉동실 증발기(15)와 냉장실 증발기(16)가 설치되며, 각 증발기(15,16)의 상측에는 냉기를 송풍하는 송풍팬(17,18)이 설치된다.In the refrigerator, as shown in FIG. 1, a freezing compartment 11 is formed at an upper side of the main body 10, and a refrigerating chamber 12 is provided at a lower side of the refrigerator 10, and the front side of the freezing chamber 11 and the refrigerating chamber 12 is provided. Doors 13 and 14 for opening and closing them are provided. In addition, a freezer compartment evaporator 15 and a refrigerator compartment evaporator 16 are respectively installed on the inner rear walls of the freezer compartment 11 and the refrigerating compartment 12, and blower fans 17 and 18 that blow cold air above the evaporators 15 and 16, respectively. ) Is installed.

특히, 냉장실(12)의 후벽 상단에는 도 2에 도시된 바와 같이, 가로방향으로 길이가 긴 증발기(16)가 설치되고, 이 증발기(16)의 주위를 감싸도록 흡입유로(19)가 마련되며, 흡입유로(19)의 양측 전면에는 냉장실(12)의 냉기를 흡입하는 흡입구(19a)가 형성된다. 또한, 냉장실(12)의 후벽 중앙에는 상하로 길게 형성되어 냉기의 토출을 안내하는 토출유로(20)가 마련되며, 이 토출유로(20)의 전면에는 다수의 토출구(20a)가 형성된다. 이때, 가로방향의 흡입유로(19)와 만나는 토출유로(20)의 상부는 흡입유로(19)의 전방에 별도의 유로를 이루도록 구성되며, 그 상단부가 흡입유로(19)의 중앙 상부와 상호 연통하도록 구성된다. 그리고 두 유 로(19,20)가 상호 연통되는 증발기(16)의 상측에 냉기를 송풍하는 송풍팬(18)이 설치된다.In particular, as illustrated in FIG. 2, an evaporator 16 having a long length in the transverse direction is installed at an upper end of the rear wall of the refrigerating chamber 12, and a suction flow path 19 is provided to surround the evaporator 16. On both front surfaces of the suction passage 19, suction ports 19a for sucking cold air from the refrigerating chamber 12 are formed. In addition, a discharge passage 20 is formed in the center of the rear wall of the refrigerating chamber 12 to extend up and down to guide the discharge of cold air, and a plurality of discharge ports 20a are formed on the front surface of the discharge passage 20. At this time, the upper portion of the discharge flow path 20 which meets the horizontal suction flow path 19 is configured to form a separate flow path in front of the suction flow path 19, the upper end of the communication with the central upper portion of the suction flow path (19). Is configured to. And a blowing fan 18 for blowing cold air is installed on the upper side of the evaporator 16, the two passages (19, 20) are in communication with each other.

따라서, 종래 냉장고의 냉장실(12)은 송풍팬(18)의 구동될 때 양측 흡입구(19a)를 통해 흡입유로(19) 내부로 흡입된 냉기가 증발기(16)와 열교환을 한 후, 증발기(16)의 중앙 상부를 통해 토출유로(20)로 흐르고, 토출유로(20)를 따라 하부로 이동되는 냉기는 토출유로(20) 전면에 형성된 토출구(20a)를 통해 다시 냉장실(12)로 공급된다.Therefore, in the refrigerator compartment 12 of the conventional refrigerator, after the cold air sucked into the suction passage 19 through both suction ports 19a when the blower fan 18 is driven exchanges with the evaporator 16, the evaporator 16 The cold air flowing into the discharge passage 20 through the upper portion of the center and moved downward along the discharge passage 20 is supplied back to the refrigerating chamber 12 through the discharge port 20a formed at the front of the discharge passage 20.

그런데, 이와 같이 구성된 종래 냉장고의 냉장실(12) 냉기순환구조는 토출유로(20)가 후벽 중앙에 상하로 형성되고 그 전면에 토출구(20a)가 형성되어 있기 때문에 토출되는 냉기가 냉장실(12)의 중앙으로 집중되어, 냉기를 구석진 부분까지 골고루 공급하는데 한계가 있었다.However, the cold air circulation structure of the refrigerator compartment 12 of the conventional refrigerator configured as described above has a discharge passage 20 formed up and down at the center of the rear wall, and a discharge port 20a is formed at the front side thereof. Concentrated in the center, there was a limit to evenly supplying cold air to the corners.

또한, 종래 냉기순환구조는 토출유로(20)의 상부가 흡입유로(19)의 전방에 별도의 유로를 이루도록 구성되기 때문에 도 1에 도시된 바와 같이, 냉장실(12)의 후벽 상부가 냉장실(12) 내부쪽으로 돌출하게 되어 냉장실(12)의 내부용적을 줄이는 원인이 되었다.In addition, in the conventional cold air circulation structure, since the upper portion of the discharge passage 20 forms a separate passage in front of the suction passage 19, as illustrated in FIG. 1, the rear wall upper portion of the refrigerating chamber 12 is the refrigerating chamber 12. Protruding inwardly has caused the internal volume of the refrigerating chamber 12 to be reduced.

또한, 종래 냉장고는 냉기를 생성하는 증발기(16)가 냉장실(12)의 후벽 상부에 설치되어 있기 때문에, 증발기(16)의 제상시에 발생되는 제상수를 받아내기 위해 증발기(16)의 하부에 별도의 제상수받이(21)를 설치해야 하는 복잡함이 있었다.In the conventional refrigerator, since the evaporator 16 which generates cold air is installed in the upper part of the rear wall of the refrigerating chamber 12, the refrigerator is provided in the lower part of the evaporator 16 to receive defrost water generated at the time of defrosting the evaporator 16. There was a complex need to install a separate defrosting receiver (21).

본 발명은 이와 같은 문제점들을 해결하기 위한 것으로, 본 발명의 주목적은 냉장실 후벽의 냉기순환구조를 개선하여, 토출되는 냉기가 냉장실 전역에 고른 분포를 이루도록 하는 동시에 냉장실의 내부용적이 커지는 냉장고를 제공하는 것이다.The present invention is to solve the above problems, the main object of the present invention is to improve the cold air circulation structure of the rear wall of the refrigerating compartment, to provide a refrigerator in which the discharged cold is evenly distributed throughout the refrigerating compartment and at the same time the internal volume of the refrigerating compartment is increased. will be.

본 발명의 다른 목적은 증발기의 설치위치를 변경하여 별도의 제상수받이가 없이도 제상수를 용이하게 처리할 수 있게 함으로써, 냉장실의 후벽 내부구조가 단순해지는 냉장고를 제공하는 것이다.Another object of the present invention is to provide a refrigerator in which the internal structure of the rear wall of the refrigerating chamber is simplified by changing the installation position of the evaporator so that the defrost water can be easily treated without a separate defrosting receiver.

한편, 이와 같이 구성된 냉장고는 도 3에 도시된 바와 같이, 증발기(36)가 냉장실(32) 후벽 하부에 설치되기 때문에 증발기(36)의 제상시에 발생되는 제상수가 냉기생성실(40)의 하부에 모이게 되므로, 별도의 제상수받이가 필요 없게 된다. 즉 냉기생성실(40)의 내부구성이 단순해진다. 이때, 냉기생성실(40)의 하단에는 증발기(36)의 제상시에 하부에 고이는 제상수의 배출을 위한 배수관(50)이 연결된다. On the other hand, in the refrigerator configured as described above, as shown in FIG. 3, since the evaporator 36 is installed below the rear wall of the refrigerating chamber 32, the defrost water generated at the defrost of the evaporator 36 is removed from the cold air generating chamber 40. Since it is collected in the lower portion, there is no need for a separate defrosting receiver. In other words, the internal configuration of the cold air generating chamber 40 is simplified. At this time, the lower end of the cold air generating chamber 40 is connected to the drain pipe 50 for discharging the defrost water accumulated in the lower portion during the defrost of the evaporator 36.

다음은 이와 같이 구성된 본 발명에 따른 냉장고의 냉장실 냉기순환동작을 설명한다.Next, the refrigerator compartment cold air circulation operation of the refrigerator according to the present invention configured as described above will be described.

송풍팬(38)이 구동되면, 냉장실(32)의 내부공기는 흡입유로(41)의 전면에 형성된 다수의 흡입구(42)를 통해 흡입유로(41)의 내부로 유입되고, 흡입유로(41)의 공기는 냉기생성실(40)과 연통된 하부를 통해 증발기(36)가 설치된 냉기생성실(40) 내부로 유입된다. When the blower fan 38 is driven, the internal air of the refrigerating chamber 32 is introduced into the suction channel 41 through a plurality of suction ports 42 formed in front of the suction channel 41, and the suction channel 41 is formed. Air flows into the cold air generating chamber 40 in which the evaporator 36 is installed through the lower portion communicating with the cold air generating chamber 40.

냉기생성실(40)로 유입된 공기는 증발기(36)와 열교환을 하여 차가운 냉기가 되고, 이 냉기는 토출유로(43)의 토출구(44)를 통해 다시 냉장실 내부로 공급된다. 이때 토출유로(43) 양측에는 다수의 가지유로(45)가 마련되어 있기 때문에 토출유로(43)를 따라 흐르는 냉기는 토출유로(43) 전면의 토출구(44) 뿐만 아니라, 각 가지유로(45)의 토출구(46)로 분산되어 토출된다. 즉, 냉기가 냉장실(32) 후벽에 분산 배치된 토출구(44,46)를 통해 고른 분포로 토출된다.The air introduced into the cold air generating chamber 40 exchanges heat with the evaporator 36 to form cold cold air, and the cold air is supplied back into the refrigerating chamber through the discharge port 44 of the discharge passage 43. At this time, since a plurality of branch passages 45 are provided at both sides of the discharge passage 43, the cold air flowing along the discharge passage 43 is not only the discharge port 44 at the front of the discharge passage 43, but also each branch passage 45. Dispersed in the discharge port 46 is discharged. That is, the cold air is discharged in an even distribution through the discharge ports 44 and 46 distributed in the rear wall of the refrigerating chamber 32.

그리고 냉장실(32) 내부로 토출된 냉기는 냉장실(32)에 수용된 저장물을 냉각시킨 후 다시 흡입유로(41)로 흡입이 반복되면서 냉장실(32) 내부의 지속적인 냉기 순환이 이루어진다.In addition, the cold air discharged into the refrigerating chamber 32 cools the storage stored in the refrigerating chamber 32, and then the suction is repeated into the suction flow path 41 to continuously circulate the cold air in the refrigerating chamber 32.

한편, 증발기(36)의 제상시에 발생되는 제상수는 냉기생성실(40)의 하부에 고이는데, 이 제상수는 냉기생성실(40)의 하부에 연결된 배수관(50)을 따라 외부로 배출된다.(도 3참조)On the other hand, the defrost water generated during the defrost of the evaporator 36 is collected in the lower portion of the cold air generating chamber 40, the defrost water is discharged to the outside along the drain pipe 50 connected to the lower portion of the cold air generating chamber 40. (See FIG. 3)

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 냉장고의 냉장실 냉기순환구조는 냉기가 토출되는 토출구가 냉장실의 후벽에 고루 배치되어 있기 때문에 냉장실의 구석까지 냉기의 공급이 원활할 뿐만 아니라, 흡입유로와 토출유로가 겹치지 않도록 구성되기 때문에 냉장실 후면벽의 두께가 얇아져서 냉장실의 내부용적이 커지는 효과가 있다. As described in detail above, in the refrigerator compartment cold air circulation structure of the refrigerator according to the present invention, since the discharge port through which the cold air is discharged is disposed evenly on the rear wall of the refrigerator compartment, the cold air is not only smoothly supplied to the corner of the refrigerator compartment, but also the suction flow path and the discharge path. Since the flow paths do not overlap, the thickness of the rear wall of the refrigerating compartment becomes thin, thereby increasing the internal volume of the refrigerating compartment.

또한, 본 발명은 증발기를 수용하는 냉기생성실이 하부에 위치되기 때문에 증발기의 제상시에 발생되는 제상수가 냉기생성실의 하부에 고임으로써 별도의 제상수받이가 없이도 제상수를 용이하게 처리할 수 있고, 이로써 냉장실의 후벽 내부구조가 단순해지는 효과가 있다.






In addition, the present invention is because the cold air generating chamber for accommodating the evaporator is located in the lower portion of the defrosting water generated during the defrost of the evaporator is accumulated in the lower portion of the cold air generating chamber to easily process the defrost water without a separate defrost receiving water. This makes it possible to simplify the internal structure of the rear wall of the refrigerating compartment.
