Description

냉장고의 냉기순환 구조{structure for circulating cold air in refrigerator}Structure for circulating cold air in refrigerator

본 발명은 내장고에 관한 것으로, 보다 상세하게는 증발기에 의해 냉각된 냉기가 냉동실 및 냉장실로 공급되어 상기 증발기가 설치된 공간으로 다시 유입되는 냉장고의 냉기순환 구조에 관한 것이다.The present invention relates to an internal storage compartment, and more particularly, to a cold air circulation structure of a refrigerator in which cold air cooled by an evaporator is supplied to a freezing compartment and a refrigerating compartment and introduced back into a space where the evaporator is installed.

일반적으로 냉장고는 냉매의 압축, 응축, 팽장, 증발과정으로 이루어지는 냉동사이클을 이용하여 식품을 신선하게 장기간 동안 보관하는 용도로 사용되는 기기이다.In general, a refrigerator is a device used for storing food for a long period of time using a refrigeration cycle consisting of compression, condensation, expansion, and evaporation of a refrigerant.

상기 냉장고의 구성을 도 1을 참조하여 설명하면 다음과 같다.The configuration of the refrigerator will be described with reference to FIG. 1.

냉장고는 크게 본체(100)와, 식품을 냉동 보관하기 위한 냉동실(10) 및 식품을 냉장 보관하기 위한 냉장실(20)로 나누어지며, 상기 냉동실(10) 후방에는 증발기(30)가 설치되고, 상기 증발기(30) 상부에는 냉기를 유동시키는 송풍팬(31) 및 상기 송풍팬(31)을 구동시키는 모터(32)가 설치된다.The refrigerator is largely divided into a main body 100, a freezing compartment 10 for freezing food and a refrigerating compartment 20 for refrigeration of food, and an evaporator 30 is installed at the rear of the freezing compartment 10. The blowing fan 31 for flowing cold air and the motor 32 for driving the blowing fan 31 are installed above the evaporator 30.

상기 송풍팬(31) 전방에는 냉기의 토출영역과 흡입영역을 구분짓는 슈라우드(40)가 설치되며, 상기 슈라우드(40) 전방에는 상기 송풍팬(31)을 통과한 냉기를 냉동실(10) 및 냉장실(20)로 보내기 위한 그릴(41)이 설치되어 냉기의 유로를 형성하게 된다.A shroud 40 is formed in front of the blower fan 31 to distinguish the discharge area and the suction area of the cold air, and the cold air passing through the blower fan 31 in front of the shroud 40 is freezer compartment 10 and a refrigerating compartment. Grill 41 to be sent to 20 is installed to form a flow path of cold air.

이와 같이 구성된 냉장고에서 냉기가 순환하는 과정은 다은과 같다.The cold air is circulated in the refrigerator configured as described above.

냉장고가 구동되면 고온의 냉매는 압축기(33)에 의해 압축된 후 응축기(34)에 의해 응축되어 상기 증발기(30)로 유입된다.When the refrigerator is driven, the hot refrigerant is compressed by the compressor 33 and then condensed by the condenser 34 and introduced into the evaporator 30.

상기 증발기(30) 주위의 공기는 증발기(30) 내부를 지나는 응축된 냉매와의 열교환에 의해 온도가 낮아져 냉기가 된다.The air around the evaporator 30 is cooled by heat exchange with the condensed refrigerant passing through the evaporator 30 to become cold air.

상기 냉기의 일부는 송풍팬(31)에 의해 슈라우드(40)와 그릴팬(41) 사이의 연결유로(42)를 지나 냉장실(20) 후면에 형성된 냉장냉기토출구(21)를 통해 냉장실(20)로 공급되며, 그 나머지는 그릴(41)에 형성된 냉동냉기토출구(11)를 통해 냉동실(10)로 공급된다.A portion of the cold air passes through the connection passage 42 between the shroud 40 and the grill pan 41 by the blowing fan 31 and through the refrigerating cold air outlet 21 formed at the rear side of the refrigerating compartment 20. The remaining portion is supplied to the freezing chamber 10 through the freezing cold air outlet 11 formed in the grill (41).

한편, 상기 냉동실(10) 내부로 공급된 냉기는 냉동실(10) 전방 저면에 형성된 냉동냉기유입구(12)로 유입되고, 상기 냉장실로 공급된 냉기는 냉장실(20) 전방 상면에 형성된 냉장냉기유입구(22)로 유입되어 냉기유입로(43)를 지나 증발기(30) 주위로 이동하게 된다.On the other hand, the cold air supplied into the freezer compartment 10 is introduced into the freezing cold air inlet 12 formed on the bottom surface of the freezer compartment 10, the cold air supplied to the refrigerating compartment cold storage inlet formed on the front surface of the refrigerator compartment 20 ( 22 is passed through the cold air inlet path 43 is moved around the evaporator (30).

그러나, 종래의 냉장고 다음과 같은 문제점을 나타내었다.However, conventional refrigerators have shown the following problems.

상기 냉장고는 냉기가 토출될 수 있는 면적이 한정되어 있어 상기 냉기의 유동저항이 증가하므로, 상기 냉기의 순환에 의한 소음이 발생하고, 냉기 순환력을 발생시키는 상기 모터의 부하가 커져 소비전력이 증가하는 문제점을 나타내었다.Since the refrigerator has a limited area in which cold air can be discharged, the flow resistance of the cold air is increased, so that noise caused by circulation of the cold air is generated and the load of the motor generating the cold air circulation force is increased, thereby increasing power consumption. The problem was shown.

또한, 상기 냉동실 및 냉장실 내부로의 냉기공급을 위한 토출구가 상기 냉장고의 후방에 형성되어, 냉기의 공급방향이 후방으로만 한정되어 있다.In addition, a discharge port for supplying cold air into the freezing compartment and the refrigerating compartment is formed at the rear of the refrigerator, and the supply direction of the cold air is limited to the rear only.

따라서, 냉장고에 적제된 식품의 양이 많은 경우에는 냉기의 원활한 순환이 이루어지지 못하고 내장고 내부의 온도분포가 균일하게 형성되지 못하여, 상기 냉장고의 실질적인 부피가 줄어들어 식품의 일부에 냉기가 공급되지 않아 그 신선도가 떨어지는 문제점을 나타내었다.Therefore, when the amount of food stored in the refrigerator is large, the circulation of the cold air is not made smoothly and the temperature distribution inside the interior is not uniformly formed, and the substantial volume of the refrigerator is reduced, so that the cold air is not supplied to a part of the food. The freshness was shown to be a problem.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출한 것으로서, 증발기에서 냉각된 냉기가 냉동실 및 냉장실의 후방 및 측면으로 공급된 후 상기 냉동실 및 냉장실의 전방 및 측면으로 유입되도록 하여, 상기 냉기가 공급 및 유입될 수 있는 면적을 증가시키고 냉기의 공급이 여러 방향에서 이루어지도록 하는데 그 목적이 있다.The present invention has been made in order to solve the above problems, the cold air cooled in the evaporator is supplied to the rear and side of the freezer compartment and the refrigerating compartment to be introduced to the front and side of the freezer compartment and the refrigerating compartment, the cold air supply and The purpose is to increase the area that can be introduced and to ensure that the supply of cold air is made in several directions.

상기와 같은 목적을 달성하기 위해 본 발명은, 증발기에서 냉각된 냉기가 냉동실 및 냉장실 각각의 측면으로 공급되고 유입될수 있도록, 상기 냉동실 및 냉장실 좌·우측면에 냉기의 공급 및 유입수단이 구비된 것을 특징으로 한다.In order to achieve the above object, the present invention is characterized in that the supply and inlet means of the cold air is provided on the left and right sides of the freezer compartment and the refrigerating compartment, so that the cold air cooled in the evaporator can be supplied to each side of the freezer compartment and the refrigerating compartment. It is done.

이하, 본 발명의 실시예를 첨부된 도면을 참조하여 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

종래 기술과 동일한 구성요소에 대한 자세한 설명은 생략하기로 한다.Detailed description of the same components as in the prior art will be omitted.

도 3은 본 발명에 따른 냉장고 냉기 순환구조에 있어서, 냉동실(10)로 공급되는 냉기의 순환구조를 보인 도면이다.3 is a view showing the circulation structure of the cold air supplied to the freezer compartment 10 in the refrigerator cold air circulation structure according to the present invention.

도시된 바와 같이, 상기 냉동실(10) 후방에 설치된 그릴(41)에는 증발기에서 냉각된 냉기가 상기 냉동실(10)로 공급되도록 다수개의 냉동냉기토출구(11)가 형성된다.As shown, a plurality of freezing cold air outlets 11 are formed in the grill 41 installed behind the freezing compartment 10 so that the cold air cooled in the evaporator is supplied to the freezing compartment 10.

한편, 상기 냉동실(10) 좌·우측벽 상부 모서리 부분에는 증발기에서 냉각된 냉기가 상기 냉동실(10)의 측면에서도 공급될 수 있도록 냉동냉기토출덕트(50)가 각각 구비된다.Meanwhile, freezing air discharge ducts 50 are provided at upper edge portions of the left and right walls of the freezing compartment 10 so that the cool air cooled in the evaporator may be supplied from the side surface of the freezing compartment 10, respectively.

상기 각각의 냉동냉기토출덕트(50)는 그 내부에 다수개의 냉동냉기토출구(11)가 형성되며, 그릴(41) 후방에서 온도가 낮아진 냉기가 흡입되도록 상기 그릴(41) 및 슈라우드(40) 사이의 냉기유로와 각각 연통되어 있고, 그 반대편은 냉기의 손실을 방지하기 위해 각각 차단된다.Each of the freezing cold air discharging duct 50 has a plurality of freezing cold air discharging outlets 11 formed therein, and between the grill 41 and the shroud 40 so that cold air having a lower temperature is sucked from the rear of the grill 41. It is in communication with each of the cold air flow paths, and the opposite sides are respectively blocked to prevent the loss of cold air.

또한, 상기 각각의 냉동냉기토출덕트(50)는 그 구비되는 위치가 냉동실(10) 좌·우측벽 상·하부 어디에도 가능하나, 냉동실(10) 상부 모서리에 구비되는 것이가장 바람직하며 그 이유는 다음과 같다.In addition, each of the freezing cold air discharge duct 50 is located in the upper and lower portions of the left and right walls of the freezer compartment 10, but is most preferably provided in the upper corner of the freezer compartment 10. Same as

공기는 온도가 낮을수록 그 밀도가 무거워져 아래로 하강하는 성질이 있기 때문에, 냉기가 상기 냉장실(10)에 적제된 식품 주위를 고르게 순환하기 위해서는 각각의 냉동냉기토출덕트(50)는 상기한 위치에 구비되어야 한다.Since air has a property that the density of the air is lower as the temperature is lowered and descends downward, each of the freezing cold air discharge ducts 50 is located at the above-described position in order to circulate the food evenly around the food stored in the refrigerating compartment 10. Should be provided.

그리고, 상기 냉동실(10) 전방 저면 및 좌·우측벽 하부 모서리 부분에는 상기 냉동냉기토출구(11)에서 공급된 냉기를 다시 유입하기 위한 다수개의 냉동냉기유입구(12)가 형성되며, 상기 각각의 냉동냉기유입구(12)는 냉기유입로와 연통된다.In addition, a plurality of freezing cold air inlets 12 are formed at the front bottom surface of the freezing compartment 10 and lower edges of the left and right walls to introduce cold air supplied from the freezing cold air outlet 11 again. The cold air inlet 12 communicates with the cold air inlet.

상기 냉동냉기유입구(12)가 종래와는 다르게 냉동실 좌·우측벽 하부 모서리 부분에도 형성되는 이유는 다음과 같다.The reason why the freezing cold air inlet 12 is also formed in the lower corners of the left and right walls of the freezer compartment is different from the prior art as follows.

상기 각각의 냉동냉기토출덕트(50)에 형성된 냉동냉기토출구(11)에 의해 냉동실(10) 내부로 공급되는 냉기의 양이 증가하므로, 상기 냉동실(10) 좌·우측벽 하부 모서리 부분에도 냉동냉기유입구(12)를 형성하여 냉기의 순환을 원활히 하여야 한다.Since the amount of cold air supplied into the freezing chamber 10 is increased by the freezing cold air outlet 11 formed in each of the freezing cold air discharge ducts 50, the freezing cold air is also formed at the lower edges of the left and right walls of the freezing compartment 10. Inlet 12 should be formed to facilitate the circulation of cold air.

이는, 냉기의 공급면적과 유입면적을 일치시켜 냉동실(10) 내에서 발생하는 냉기의 유동저항을 최소화 하기위한 것이다.This is to minimize the flow resistance of the cold air generated in the freezing chamber 10 by matching the supply area and the inflow area of the cold air.

이하, 상기한 바와 같은 냉기순환 구조를 갖는 냉장고 냉동실(10)에서 냉기가 순환하는 과정에 대해 설명하고자 한다.Hereinafter, a process in which cold air circulates in the refrigerator freezer compartment 10 having the cold air circulation structure as described above will be described.

증발기(30)에서 열교환되어 온도가 낮아긴 냉기는 모터(32) 및 송풍팬(31전에 의해 발생된 순환력에 의해 슈라우드(40)와 그릴(41) 사이로 흡입되어, 그 일부는 상기 슈라우드(40)와 그릴(41) 사이의 연결유로(42)를 지나 냉장실(20)로 공급된다.The cold air heat exchanged in the evaporator 30 to lower the temperature is sucked between the shroud 40 and the grill 41 by the circulation force generated by the motor 32 and the blower fan 31, and part of the shroud 40 ) Is supplied to the refrigerating chamber 20 through the connection flow path 42 between the grill 41 and.

한편, 냉장실(20)로 공급되지 않은 냉기는 상기 그릴(41)에 형성된 냉동냉기토출구(11) 및 상기 냉동냉기토출덕트(50)에 형성된 냉동냉기토출구(11)를 통해 냉동실(10) 내부로 공급되어 그 내부에 적제된 식품을 냉동시키게 된다.On the other hand, the cold air not supplied to the refrigerating chamber 20 into the freezing chamber 10 through the freezing cold air discharge port 11 formed in the grill 41 and the freezing cold air discharge port 11 formed in the freezing cold air discharge duct 50. It is supplied to freeze the food stored therein.

이러한 과정에서, 상기 각각의 냉동냉기토출덕트(50)에 형성된 냉동냉기토출구(11)에 의해 냉기가 냉동실(10) 내부로 공급되는 면적이 증가하여 송풍팬과 냉동실(10) 사이에서 발생되는 냉기의 유로저항이 감소한다.In this process, the area where the cold air is supplied into the freezing compartment 10 is increased by the freezing cold air outlet 11 formed in each of the freezing cold air discharge ducts 50, and thus the cold air generated between the blower fan and the freezing compartment 10 is increased. The flow path resistance decreases.

또한, 상기 냉동실(10)에 많은 양의 식품이 적제된 경우에도, 냉기의 공급이 여러 방향에서 이루어지므로 고른 온도분포가 형성되어 식품의 신선도가 유지된다.In addition, even when a large amount of food is stored in the freezer compartment 10, since the supply of cold air is made in various directions, an even temperature distribution is formed to maintain the freshness of the food.

상기 냉동실(10) 내부를 순환한 냉기는 냉동실(10) 전방 저면 및 좌·우측벽 하부 모서리 부분에 형성된 각각의 냉동냉기유입구(12)로 유입되어 냉기유입로(43)를 지나 증발기(30) 주위로 이동하게된다.The cold air circulated inside the freezing compartment 10 is introduced into each freezing cold air inlet 12 formed at the front bottom surface of the freezing compartment 10 and lower edges of the left and right walls, and passes through the cold air inlet passage 43 to the evaporator 30. Will move around.

상기 각각의 냉동냉기유입구(12)는 상기 각각의 냉동냉기토출구(11)와 그 총면적이 동일하여 상기 냉동실(10) 내부에서 발생되는 냉기의 유로저항이 감소되므로, 냉동실(10) 내부에서의 냉기가 원활히 순환하게 된다.Each of the freezing cold air inlets 12 has the same total area as the freezing cold air outlet 11, so that flow resistance of the cold air generated in the freezing compartment 10 is reduced, so that the cold air in the freezing compartment 10 is reduced. Will cycle smoothly.

한편, 도 3에 도시된 바와 같이 본 발명에 따른 냉기순환 구조를 갖는 냉장고 냉장실(20)의 후면에는 슈라우드(40)와 그릴(41) 사이의 연결유로를 지나온 냉기가 냉장실(20)로 공급되기 위해 다수개의 냉장냉기토출구(21)가 형성되고, 그 좌·우측벽에는 다수개의 냉장냉기토출덕트(60)가 각각 구비된다.Meanwhile, as illustrated in FIG. 3, cold air passing through a connection flow path between the shroud 40 and the grill 41 is supplied to the refrigerating compartment 20 on the rear side of the refrigerator refrigerating compartment 20 having the cold air circulation structure according to the present invention. A plurality of refrigerated cold air outlet 21 is formed, and the left and right walls are provided with a plurality of refrigerated cold air discharge ducts 60, respectively.

상기 각각의 냉장냉기토출덕트(60)는 그 내부에 다수개의 냉장냉기토출구(21)가 각각 형성되며, 연결유로(42)를 지나는 냉기가 흡입되기 위해 상기 냉장실(20) 후방의 냉기유로와 각각 연통되고, 그 반대편은 냉기의 손실을 방지하기 위해 각각 차단된다.Each of the refrigeration cold air discharge duct 60 has a plurality of refrigeration cold air discharge ports 21 formed therein, respectively, and the cold air flow path behind the refrigerating chamber 20 to inhale cold air passing through the connection flow path 42. Communicating with each other, the other side is blocked to prevent the loss of cold air.

또한, 상기 냉장실(20) 전방 상면 및 좌·우측벽 상부 모서리 부분에는 각각의 냉장냉기토출구(21)에서 냉장실(20) 내부로 공급된 냉기를 유입하기 위한 다수개의 냉장냉기유입구(22)가 형성되며, 상기 각각의 냉장냉기유입구(22)는 냉기유입로와 연통된다.In addition, a plurality of refrigerating cool air inlets 22 are formed at the front upper surface of the refrigerating compartment 20 and upper edges of the left and right walls to introduce cold air supplied into the refrigerating compartment 20 from each of the refrigerating refrigerating air outlets 21. Each refrigeration cold air inlet 22 is in communication with the cold air inlet.

그리고, 상기 냉장냉기유입구(22)의 총면적은 냉장냉기토출구(21)의 총면적과 같다.The total area of the refrigerated cold air inlet 22 is the same as the total area of the refrigerated cold air outlet 21.

이와 같은 냉기순환 구조를 갖는 냉장고 냉장실의 냉장냉기가 순환하는 과정은 냉동실의 냉기가 순환하는 과정과 동일하다.The process of circulating the refrigerated cold of the refrigerator refrigerating compartment having the cold air circulation structure is the same as the process of circulating the cold air of the freezing compartment.

이상에서와 같이 본 발명은 냉장고를 구성하는 냉동실 및 냉장실의 좌·우측벽 소정의 위치에 다수의 냉기토출구가 형성된 냉동냉기토출덕트 및 냉장냉기토출덕트를 구비하여 냉기가 토출되는 면적을 증가시키고, 여러 방향에서 냉기가 토출되도록 한다.As described above, the present invention includes a refrigeration cold discharge duct and a refrigeration cold discharge duct having a plurality of cold air discharge ducts formed at predetermined positions of the left and right walls of the freezer compartment and the refrigerating compartment constituting the refrigerator to increase the area where cold air is discharged. Allows cold air to be discharged in various directions.

또한, 상기 냉동실 전방 저면 및 좌·우측벽 하부 모서리 부분과 상기 냉장실 전방 상면 및 좌·우측벽 상부 모서리 부분에 상기 냉기토출구와 총면적이 동일한 다수개의 냉기유입구를 각각 형성하여 냉기가 유입되도록 한다.In addition, a plurality of cold air inlets having the same total area as the cold air discharge ports are formed on the freezer compartment front bottom surface and the lower edge portion of the left and right walls and the upper edge portion of the refrigerator compartment front and left and right walls, respectively, to allow cold air to flow therethrough.

따라서, 냉기가 토출되는 면적이 증가하여 송풍팬과 냉동실 및 냉장실 사이에서 발생되는 냉기의 유로저항이 감소하고, 냉동실 및 냉장실 내부에서 발생되는 냉기의 유로저항이 감소하여, 냉기의 순환에 의한 소음을 줄일 수 있고, 냉기 순환력을 발생시키는 상기 모터의 부하가 작아져 소비전력을 감소시킬 수 있는 장점이 있다.Therefore, the area where the cold air is discharged increases, thereby reducing the flow path resistance of the cold air generated between the blower fan, the freezer compartment and the refrigerating chamber, and reducing the flow path resistance of the cold air generated inside the freezer compartment and the refrigerator compartment, thereby reducing noise caused by the circulation of the cold air. There is an advantage that can be reduced, the load of the motor that generates the cold air circulation force is reduced to reduce the power consumption.

그리고, 상기 냉기의 토출이 여러 방향에서 이루어져 고른 온도분포가 형성되므로, 냉장고에 많은 양의 식품이 적제되어도 그 신선도를 유지시킬 수 있는 장점이 있다.In addition, since the discharge of the cold air is formed in various directions to form an even temperature distribution, there is an advantage that the freshness can be maintained even when a large amount of food is loaded in the refrigerator.
