Description

냉장고의 냉기공급장치{APPARATUS FOR SUPPLYING COLD AIR IN REFRIGERATOR}Refrigeration air supply unit {APPARATUS FOR SUPPLYING COLD AIR IN REFRIGERATOR}

본 발명은 냉장고에 관한 것으로, 특히 냉장고 내부에 냉기를 공급하는 냉기공급장치에 관한 것이다.The present invention relates to a refrigerator, and more particularly to a cold air supply device for supplying cold air into the refrigerator.

종래의 냉장고는 식품을 냉동보관하는 냉동실이 식품을 냉장보관하는 냉장실의 상부에 설치되어 있는 구조가 일반적이지만, 용량이 큰 대형 냉장고에는 냉동실과 냉장실이 좌우에 설치되어 보다 많은 양의 식품을 보관할 수 있도록 된 사이드 바이 사이드형(side by side type)의 냉장고가 많이 적용되어 사용된다.Conventional refrigerators generally have a structure in which a freezer for freezing food is installed at the upper part of a refrigerating compartment for storing food. However, in a large refrigerator, a freezer and a refrigerating compartment are installed on the left and right sides to store more food. Many side by side type refrigerators are used.

종래의 사이드 바이 사이드 냉장고의 일례를 도 1에 도시하였는 바, 그 구성을 간략하게 설명한다.An example of a conventional side by side refrigerator is illustrated in FIG. 1, and the configuration thereof will be briefly described.

식품을 냉동보관하는 냉동실(10)과 식품을 냉장보관하는 냉장실(20)이 좌우로 설치되고, 그 사이에 냉장실(20)과 냉동실(10)을 구분하는 멀리언(mullion)벽(30)이 설치되어 있다.A freezer compartment 10 for storing food and a refrigerator compartment 20 for storing food are installed on the left and right side, and a mullion wall 30 separating the refrigerator compartment 20 and the freezer compartment 10 is interposed therebetween. It is installed.

상기 냉동실(10)의 후방 상부에는 증발기(미도시)를 거쳐 냉각된 냉기를 고내로 흡입하여 순환시키는 팬(2)이 설치되어 있고, 이 팬(2)의 전면에는 팬(2)의 회전으로 흡입된 냉기가 토출되는 오리피스(orifice)가 형성된 고정부재(1)가 설치되어 있고, 상기 고정부재(1)의 전면에는 냉기를 아이스 메이커(ice maker)(9)에 토출시키는 실드팬(3)이 설치되어 있고, 상기 팬(2)의 하부에는 냉기를 냉동실(10) 내에 토출하는 커버오거(4)가 설치되어 있어 상기 실드팬(3)과 커버오거(4), 멀리언벽(30)으로 구성되는 일정 공간을 갖게 된다.The rear of the freezer compartment 10 is provided with a fan (2) for sucking and circulating the cold air cooled through the evaporator (not shown), the front of the fan (2) by the rotation of the fan (2) A fixing member 1 having an orifice for discharging sucked cold air is provided, and a shield pan 3 for discharging cold air to an ice maker 9 on the front surface of the fixing member 1. And a cover auger 4 for discharging cold air into the freezing chamber 10 is provided below the fan 2 to the shield pan 3, the cover auger 4, and the mullion wall 30. It has a certain space that is configured.

상기 멀리언벽(30)에는 상기 팬(2)에 의해 토출되는 냉기를 냉장실(20) 내로 유입시킬 수 있도록 냉매토출구(31)가 설치되어 있다.The mullion wall 30 is provided with a refrigerant discharge port 31 so that the cold air discharged by the fan 2 can be introduced into the refrigerating chamber 20.

상기 냉장실(20)의 내부에는 식품을 얹을 수 있는 다수개의 선반(21)이 일정간격을 두고 설치되어 있고, 냉장실(20)의 상부에는 상기 냉매토출구(31)와 연통된 토출덕트(5)가 설치되어 있고, 냉장실(20)의 하부에는 토출된 냉기를 증발기로 유입시키는 흡입덕트(7)와, 리턴덕트(8)가 설치되어 있다.In the refrigerating chamber 20, a plurality of shelves 21 on which food can be placed is provided at a predetermined interval, and an upper portion of the refrigerating chamber 20 has a discharge duct 5 communicating with the refrigerant discharge port 31. In the lower part of the refrigerating chamber 20, the suction duct 7 and the return duct 8 which introduce the discharged cold air to an evaporator are provided.

이와 같이 구성되어 있는 냉장고의 냉기 순환 구조를 설명하면 다음과 같다.The cold air circulation structure of the refrigerator configured as described above is as follows.

전원이 인가되면 압축기(미도시)가 구동되어 냉동 사이클이 운전된다.When power is applied, a compressor (not shown) is driven to operate a refrigeration cycle.

냉동 사이클의 운전에 의해 증발기의 온도가 저하되어 냉기가 형성되고, 냉동실(10)의 상부에 설치된 팬(2)이 작동하여 상기 실드팬(3)을 통한 냉기는 얼음을 얼리는 아이스 메이커(9)에 보내져 제빙을 하고, 상기 커버오거(4)를 통한 냉기는 냉동실(10)로 공급되어 냉동실(10) 내를 순환한다.By the operation of the refrigeration cycle, the temperature of the evaporator is lowered to form cold air, and the fan 2 installed on the upper part of the freezer compartment 10 is operated so that the cold air through the shield fan 3 freezes ice. ) Is deiced, and the cold air through the cover auger (4) is supplied to the freezing chamber (10) to circulate in the freezing chamber (10).

상기 팬(2)에 의해 공급된 냉기의 일부는 상기 멀리언벽(30)에 형성된 냉매토출구(31)로 유입되는데, 이 냉매토출구(31)는 상기 토출덕트(5)와 연통되어 있으므로 이 냉매토출구(31)에 유입된 냉기는 상기 토출덕트(5)를 통해 냉장실(20)에 토출되어 냉장실(20) 내를 순환하게 된다.A part of the cold air supplied by the fan 2 flows into the refrigerant discharge port 31 formed in the mullion wall 30. Since the refrigerant discharge port 31 communicates with the discharge duct 5, the refrigerant discharge port The cold air introduced into the 31 is discharged into the refrigerating chamber 20 through the discharge duct 5 to circulate in the refrigerating chamber 20.

냉장실(20) 내를 순환한 냉기는 상기 흡입덕트(7)와 리턴덕트(8)를 통해 증발기로 귀환되고 다시 팬(2)을 통해 토출되는 순환구조를 갖는다.The cold air circulated in the refrigerating chamber 20 has a circulation structure which is returned to the evaporator through the suction duct 7 and the return duct 8 and discharged through the fan 2 again.

상기와 같이 냉기가 순환되는 구조에서 냉장실(20) 내부의 온도가 설정 온도에 도달되면 압축기의 운전이 멈추게 되고, 이와 동시에 냉동 사이클의 운전이 정지되는 것이며, 냉장실(20)의 온도가 설정온도 이상으로 상승되면 압축기가 다시 가동되어 냉동 사이클이 운전된다.When the temperature inside the refrigerating chamber 20 reaches the set temperature in the structure in which the cold air is circulated as described above, the operation of the compressor is stopped, and at the same time, the operation of the refrigerating cycle is stopped, and the temperature of the refrigerating chamber 20 is higher than the set temperature. The compressor is restarted and the refrigeration cycle is started.

이러한 동작이 냉장실(20)의 온도를 일정하게 유지시키기 위해 전원이 인가된 상태에서 반복적으로 이루어진다.This operation is repeatedly performed while power is applied to keep the temperature of the refrigerating chamber 20 constant.

그러나, 상기와 같은 종래의 사이드 바이 사이드형 냉장고는 냉장실(20)을 냉각시키는 냉기가 냉장실(20)의 상부에서만 토출됨에 따라 상하로 길게 설치된 냉장실(20) 내가 고르게 냉각되지 않고 선반(21)으로 구분되어진 각 칸별 온도 분포가 크게 차이나는 단점이 있었다.However, in the conventional side-by-side type refrigerator as described above, as the cold air for cooling the refrigerating compartment 20 is discharged only from the upper portion of the refrigerating compartment 20, the refrigerating compartment 20 installed vertically long is not cooled evenly to the shelf 21. There was a drawback that the temperature distribution for each compartment was significantly different.

더욱이 사이드 바이 사이드형 냉장고는 냉동실(10)과 냉장실(20)가 냉장고의 전고에 걸쳐서 형성되는 것이므로 그 높이가 종래의 탑 마운트 방식 냉장고의 냉동실이나 냉장실에 비해 매우 높으므로 각 칸별 온도 분포의 차이는 더욱 심하게 나타나게 된다.Moreover, since the freezer compartment 10 and the refrigerating compartment 20 are formed over the height of the refrigerator, the side-by-side type refrigerator has a higher height than the freezer compartment or the refrigerating compartment of the conventional top mount type refrigerator. It is even worse.

또한, 냉장실(20)의 상부에서만 냉기가 토출되므로 냉장실(20) 내 전체적인 냉각속도가 늦은 단점이 있었다.In addition, since the cold air is discharged only in the upper portion of the refrigerating chamber 20, the overall cooling rate in the refrigerating chamber 20 has a disadvantage.

특히, 이와 같은 점은 냉장실(20)의 최상단에 위치한 선반(21)에 부하가 가득차면 냉기의 흐름을 막게 되므로 최상단의 부하에는 결빙이 발생되며 각 칸별 온도 차이는 더욱 크게 발생하여 냉장실(20)의 하부에는 냉기의 순환이 원활하지 않은 문제점이 있었던바, 이에 대한 보완이 요구되어 왔다.In particular, this point is to prevent the flow of cold air when the load is loaded on the shelf 21 located at the top of the refrigerating chamber 20, the freezing occurs at the top load, and the temperature difference for each compartment is greater, the refrigerating chamber 20 In the lower part of the cold air there was a problem that the circulation is not smooth, it has been required to compensate for this.

따라서, 본 발명은 상기와 같은 문제점을 감안하여 안출한 것으로서, 냉장실의 상부와 하부에 골고루 냉기가 토출되도록 하여 냉장실의 각 칸별 온도차이를 줄이고 균일한 냉각이 이루어질 수 있는 냉장고의 냉기공급장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made in view of the above problems, to provide a cold air supply device for the refrigerator to reduce the temperature difference of each compartment of the refrigerating compartment to achieve uniform cooling by discharging the cold air evenly to the upper and lower portions of the refrigerating compartment. Its purpose is to.

이하, 본 발명의 냉장고의 냉기공급장치를 첨부한 도면을 참조로 하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings the cold air supply of the refrigerator of the present invention will be described in detail.

본 발명의 냉장고는, 도 2a에 도시한 바와 같이, 냉동실(10a)과 냉장실(20a)가 멀리언(mullion)벽(30a)으로 구획되어 좌우에 설치되어 있고, 상기 냉동실(10a)의 후방에는 증발기(6)를 거쳐 냉각된 냉기를 고내로 흡입하여 순환시키는 팬(2)이 냉동실(10a)의 상부에 설치되어 있는 구성이다.In the refrigerator of the present invention, as illustrated in FIG. 2A, the freezing compartment 10a and the refrigerating compartment 20a are partitioned into mullion walls 30a and provided at left and right sides. The fan 2 which inhales and circulates the cold air cooled via the evaporator 6 is installed in the upper part of the freezer compartment 10a.

상기 팬(2)의 전면에는 팬(2)의 회전으로 흡입된 냉기가 토출되는 오리피스가 형성된 고정부재(1)가 설치되어 있다.A fixing member 1 having an orifice for discharging cold air sucked by the rotation of the fan 2 is provided on the front surface of the fan 2.

상기 증발기(6)의 전면에는 상기 고정부재(1)의 하부에 연결되도록 커버(40)가 설치되어 있고, 상기 고정부재(1)의 측부, 상기 고정부재(1)와 상기 멀리언벽(30a) 사이에는 상기 팬(2)에서 오리피스를 통과한 냉기가 흡입되는 댐퍼(60)가 설치되어 있다.The front of the evaporator 6 is provided with a cover 40 to be connected to the lower portion of the fixing member 1, the side of the fixing member 1, the fixing member 1 and the mullion wall (30a) In between the damper 60 is provided a suction of cold air passing through the orifice from the fan (2).

상기 댐퍼(60)는 상기 냉장실(20a) 내의 온도에 따라 자동적으로 유로면적이 조절되는 기능을 갖춘 것으로, 상기 팬(2)에서 토출되는 냉기가 이 댐퍼(60)를 통과할 때 냉장실(20a)의 온도에 따라 댐퍼(60)의 유로면적이 넓어지거나 좁아져서 냉장실(20a)로의 냉기 흡입양이 조절된다.The damper 60 has a function of automatically adjusting the flow path area according to the temperature in the refrigerating chamber 20a, and when the coolant discharged from the fan 2 passes through the damper 60, the refrigerating chamber 20a. According to the temperature of the damper 60, the flow path area of the damper 60 is widened or narrowed to adjust the amount of cold air suction into the refrigerating chamber 20a.

상기 댐퍼(60)는 댐퍼 커버(61)에 고정되어 상기 고정부재(1)와 상기 멀리언벽(30a) 사이에 설치된다.The damper 60 is fixed to the damper cover 61 and is installed between the fixing member 1 and the mullion wall 30a.

상기 댐퍼(60)의 하부 즉, 상기 커버(40)와 냉동실(10a) 후면벽 사이에는 상기 팬(2)에서 댐퍼(60)를 통과하여 유량이 조절된 냉기를 상기 냉장실(20a) 내로 안내하는 냉기가이드(50)가 설치되어 있다.A lower portion of the damper 60, that is, between the cover 40 and the rear wall of the freezer compartment 10a, passes the damper 60 from the fan 2 to guide the cold air having a controlled flow rate into the refrigerating compartment 20a. The cold guide 50 is provided.

상기 냉기가이드(50)는 길이가 긴 유선형의 판부재로서, 그 끝단이 멀리언벽(30a)에 접하도록 상기 커버(40)와 냉동실(10a) 후면벽 사이에 상하로 길게 장착되어 있다.The cold air guide 50 is a streamlined plate member having a long length, and is vertically mounted between the cover 40 and the rear wall of the freezer compartment 10a so that the end thereof contacts the mullion wall 30a.

상기 멀리언벽(30a)에는 상기 냉기가이드(50)를 따라 흐르는 냉기가 상기 냉장실(20a)내 상부와 하부에 골고루 공급되도록 상기 냉기가이드(50)와 접한 멀리언벽(30a)의 상부로 일정간격을 두고 다수개의 냉장실측 냉기공급공(32)이 형성되어 있다.The mullion wall 30a has a predetermined distance to the upper portion of the mullion wall 30a in contact with the cold guide 50 so that cold air flowing along the cold guide 50 is evenly supplied to the upper and lower portions of the refrigerating chamber 20a. A plurality of cold compartment side cold air supply holes 32 are formed.

또한, 상기 냉기가이드(50)의 후면에는 상기 냉기가이드(50)와 상기 냉동실(10a) 후면벽이 완전하게 밀봉되어 냉기의 누설을 방지할 수 있도록 폼(미도시)이 부착되어 있다.In addition, a foam (not shown) is attached to a rear surface of the cold air guide 50 so that the cold air guide 50 and the rear wall of the freezing chamber 10a are completely sealed to prevent leakage of cold air.

첨부한 도 3은 냉기를 고내로 흡입하여 순환시키는 팬이 냉동실의 중앙부에 설치되어 있는 냉장고에 본 발명의 냉기공급장치를 적용한 예를 도시한 것으로, 팬(2)의 상부에 설치된 커버(40b)의 후면에 냉기를 냉장실(20b)로 안내할 수 있는 냉기가이드(50b)를 설치하고, 이 냉기가이드(50b)의 하부에 상기 팬(2)에서 토출된 냉기의 유량을 조절할 수 있는 댐퍼(60)를 설치한다.FIG. 3 shows an example in which the cold air supply device of the present invention is applied to a refrigerator in which cold air is sucked into the refrigerator and circulated, and is installed at the center of the freezer compartment. A cold air guide 50b for guiding cold air to the refrigerating chamber 20b is installed at the rear of the damper 60, and a damper 60 for adjusting the flow rate of the cold air discharged from the fan 2 below the cold air guide 50b. Install).

상기 냉기가이드(50b)는 멀리언벽(30b)과 그 끝단이 접하도록 설치되고, 이 멀리언벽(30b)에는 상기 냉기가이드(50b)를 따라 흐르는 냉기가 냉장실(20b)로 토출될 수 있도록 다수개의 냉장실측 냉기공급공(32b)이 일정간격을 두고 상하로 길게 형성되어 있다.The cold air guide 50b is installed to be in contact with the end of the mullion wall 30b, and the mullion wall 30b has a plurality of cold air flowing along the cold air guide 50b to be discharged to the refrigerating chamber 20b. The refrigerating chamber side cold air supply hole 32b is formed long up and down with a predetermined interval.

상기와 같은 구성의 냉기공급장치는 팬이 냉동실의 상부에 설치된 냉장고에서와 마찬가지로 증발기(6)에서 팬(2)으로 유입된 냉기가 상기 댐퍼(60)를 지나 상기 냉기가이드(50b)를 따라 흐르다가 멀리언벽(30b)에 형성된 냉장실측 냉기공급공(32b)으로 토출되어 냉장실(20b)을 고르게 냉각시킬 수 있게 된다.In the cold air supply device having the above configuration, the cold air introduced into the fan 2 from the evaporator 6 flows along the cold air guide 50b through the damper 60 as in the refrigerator installed in the upper portion of the freezer compartment. Is discharged to the refrigerating chamber side cold air supply hole 32b formed in the mullion wall 30b to cool the refrigerating chamber 20b evenly.

본 발명의 냉장고의 냉기공급장치는 증발기의 설치공간을 이용하여 냉기유로를 구성하였으므로 기존의 공간 활용도를 높여 내용적의 저하를 발생시키지 않을 뿐 아니라 냉장실의 각 칸마다 냉기를 공급하게 되므로 냉장실의 상부와 하부에 냉기가 골고루 토출되어 냉장실의 각 칸별 온도차이를 줄이는 효과가 있다.The cold air supply device of the refrigerator of the present invention uses the installation space of the evaporator to configure the cold air flow path, thereby increasing the utilization of the existing space and not causing a decrease in the contents, and thus supplying the cold air to each compartment of the refrigerating compartment. Cold air is evenly discharged to the lower part, thereby reducing the temperature difference of each compartment of the refrigerator compartment.

따라서, 냉장실 상부에 부하가 많이 유입되더라도 냉장실 하부에 일정량의 냉기가 토출되므로 냉장실 내 균일한 냉각이 이루어질 수 있다.Therefore, even if a lot of load is introduced into the upper part of the refrigerating chamber, since a certain amount of cold air is discharged to the lower part of the refrigerating chamber, uniform cooling in the refrigerating chamber may be achieved.

또한, 냉장실의 냉각속도가 빨라지고 냉각성능이 향상될 수 있는 효과가 있다.In addition, there is an effect that the cooling rate of the refrigerating compartment is faster and the cooling performance can be improved.
