Abstract
본 발명은 냉장고의 냉기유동시스템에 관한 것으로, 더욱 상세하게는 냉장실의 냉기를 순환시키기 위한 냉장고의 냉기유동시스템에 관한 것이다. 본 발명은, 냉동실에 설치된 전체 순환 팬 외에 냉장실에 별도로 냉기 순환용 팬을 구비하는 것을 특징으로 한다. 따라서 상기 전체 순환 팬이 정지상태일때, 상기 냉장실의 팬을 회전시켜서, 냉장실 내의 냉기를 강제로 순환시킨다. 이러한 동작으로, 냉장실 전체 내부 온도분포가 균일해짐은 물론, 음식물과의 열교환이 지속적으로 이루어져서 음식물의 냉각속도가 빨라지는 효과를 얻게 된다.The present invention relates to a cold air flow system of the refrigerator, and more particularly to a cold air flow system of the refrigerator for circulating the cold air of the refrigerator compartment. The present invention is characterized by including a cold air circulation fan separately in the refrigerating chamber in addition to the entire circulation fan installed in the freezer compartment. Therefore, when the whole circulation fan is stopped, the fan of the refrigerating compartment is rotated to forcibly circulate the cold air in the refrigerating compartment. In this operation, not only the internal temperature distribution of the entire refrigerating chamber is uniform, but also the heat exchange with the food is continuously performed, so that the cooling speed of the food is increased.
Description
본 발명은 냉장고의 냉기유동시스템에 관한 것으로, 더욱 상세하게는 냉장실의 냉기를 순환시키기 위한 냉장고의 냉기유동시스템에 관한 것이다.The present invention relates to a cold air flow system of the refrigerator, and more particularly to a cold air flow system of the refrigerator for circulating the cold air of the refrigerator compartment.
종래의 냉장고는 도 1에 도시하고 있는 바와 같이, 냉장실(5)에 냉기 순환용 팬을 구비하지 않고 있다. 즉, 종래의 냉장고는 냉동실에만 냉기의 전체 순환을 위한 팬(도시하지 않음)을 구비하고 있다.The conventional refrigerator does not include the cold air circulation fan in the refrigerating chamber 5, as shown in FIG. That is, the conventional refrigerator includes a fan (not shown) for the entire circulation of cold air only in the freezer compartment.
따라서 상기 냉동실에 구비된 팬이 회전하면, 냉기공급유로와 연결되어 냉장실(5)의 각 칸마다 형성된 냉기토출구(3)를 통해서 냉기가 토출된다. 상기 냉기토출구(3)로 토출된 냉기는 음식물을 냉각시킨 후, 냉장실(5) 천정에 있는 냉장실 냉기 흡입구(1) 속으로 빨려 들어간다.Therefore, when the fan provided in the freezer compartment rotates, cold air is discharged through the cold air outlet 3 formed in each compartment of the refrigerating compartment 5 in connection with the cold air supply passage. The cold air discharged to the cold air discharge port 3 cools the food and is sucked into the cold room cold air intake port 1 in the ceiling of the refrigerator compartment 5.
한편, 상기 냉동실에 설치된 순환팬은, 냉장고에 공급될 냉기를 발생하는 냉동사이클 상의 열교환을 촉진시키기 위해서도 사용된다. 따라서 과도한 열교환시에 냉동사이클 상의 냉매의 과냉을 방지하기 위해서 소정시간 동안 또는 소정온도에 도달하기까지 상기 순환팬을 정지시키는 제어를 수행할 필요가 발생된다.On the other hand, the circulation fan installed in the freezer compartment is also used to promote heat exchange on a refrigeration cycle that generates cold air to be supplied to the refrigerator. Therefore, there is a need to perform a control to stop the circulation fan for a predetermined time or until reaching a predetermined temperature in order to prevent overcooling of the refrigerant on the refrigerating cycle during excessive heat exchange.
이와 같은 제어동작으로, 종래의 냉장고는, 냉동실에 설치된 팬이 회전하지 않는 경우가 있고, 이때 냉장실 내 냉기는 자연대류에 의해서 순환될 수 밖에 없다.In such a control operation, in a conventional refrigerator, a fan installed in a freezer compartment may not rotate, and in this case, cold air in the refrigerating compartment may be circulated by natural convection.
즉, 종래의 냉장고는, 냉동실에 설치된 팬이 회전하지 않으면, 냉장실 내부의 냉기가 자연대류에만 의존하게 된다. 따라서 냉장실 내부의 냉기가 순환되지 않고 정체되어버리면서 음식물의 냉각속도가 느려지는 문제점이 발생되었다. 또한, 종래의 냉장고는, 냉장실 내부의 냉기가 순환되지 못할때, 냉기토출구(3)에 가까운 위치에 놓여진 음식물은 과냉될 우려가 있고, 반대로 중앙부위 및 구석에 놓여진 음식물은 약냉되는 등, 음식물의 온도 분포가 균일하지 않는 문제점도 발생되었다.That is, in the conventional refrigerator, if the fan installed in the freezer does not rotate, the cold air inside the refrigerating compartment depends only on natural convection. Therefore, a problem occurs that the cooling rate of the food is slowed down as the cold air stagnates without being circulated. In the conventional refrigerator, when the cold air inside the refrigerating compartment is not circulated, food placed in a position close to the cold air discharge port 3 may be overcooled. On the contrary, the food placed in the center and the corner may be weakly cooled. There was also a problem that the temperature distribution was not uniform.
따라서 본 발명의 목적은 냉장실 내의 냉기 순환을 원활하게 할 수 있는 냉장고의 냉기유동시스템을 제공함에 있다.Accordingly, an object of the present invention is to provide a cold air flow system of a refrigerator capable of smoothly circulating cold air in a refrigerator compartment.

이하 첨부한 도면을 참조하여 본 발명에 따른 냉장고의 냉기유동시스템에 대해서 상세하게 설명한다.Hereinafter, a cold air flow system of a refrigerator according to the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명에 따른 냉장고의 냉기유동시스템의 구성도이다.2 is a block diagram of a cold air flow system of a refrigerator according to the present invention.
도시되고 있는 바와 같이, 본 발명의 냉장고는, 냉장실(15)에 냉장실 냉기를 순환시키기 위한 순환 팬(19)을 구비하고 있다. 그리고 상기 순환 팬(19)에 의해서 흡입된 냉기를 토출하는 냉기 토출구(17)도 구비하고 있다. 상기 냉기토출구(17)는, 상기 냉장실(15)의 냉장실 순환팬(19)을 설치하고 있는 냉기공급유로에 연결되어, 냉장실의 각 칸으로 냉기를 토출시킨다.As shown in the drawing, the refrigerator of the present invention includes a circulation fan 19 for circulating the refrigerating chamber cold air in the refrigerating chamber 15. A cold air discharge port 17 for discharging cold air sucked by the circulation fan 19 is also provided. The cold air discharge port 17 is connected to a cold air supply passage in which the refrigerating chamber circulation fan 19 of the refrigerating compartment 15 is installed, and discharges cold air into each compartment of the refrigerating compartment.
또한, 냉동실에 설치된 전체 순환 팬(도시하지 않음)이 회전될때, 냉기를 토출하는 냉기토출구(13a,13b)도 종래와 같이 구비하고 있다. 상기냉기토출구(13a,13b)는 상기 냉동실의 전체 순환 팬을 설치하고 있는 냉기공급유로에 연결되어, 냉장실의 각 칸으로 냉기를 토출시킨다.In addition, the cold air discharge ports 13a and 13b for discharging cold air when the entire circulation fan (not shown) installed in the freezer compartment are rotated are also provided as in the prior art. The cold air discharge ports 13a and 13b are connected to a cold air supply passage in which the entire circulation fan of the freezer compartment is installed, and discharge cold air to each compartment of the refrigerating compartment.
상기 두 팬으로부터 각각 냉기를 토출하도록 구성된 상기 냉기 토출구(17)와 상기 냉기토출구(13a,13b)는 각 칸에 나란히 형성되고, 상기 냉기 토출구(17)를 중심으로 좌우측에 상기 냉기토출구(13a,13b)를 형성하고 있다. 그리고 냉장실(15)의 천정에는 냉장실 내의 냉기를 흡입하는 흡입구(11)를 설치하고 있다.The cold air discharge ports 17 and the cold air discharge ports 13a and 13b configured to discharge cold air from the two fans, respectively, are formed side by side in the respective compartments, and the cold air discharge ports 13a and the left and right sides of the cold air discharge ports 17 are formed on the left and right sides thereof. 13b). In the ceiling of the refrigerating chamber 15, a suction port 11 for sucking cold air in the refrigerating chamber is provided.
다음은 상기 구성으로 이루어진 본 발명에 따른 냉장고의 냉기유동시스템에 대해서 설명한다.Next, a cold air flow system of a refrigerator according to the present invention having the above configuration will be described.
우선, 냉동실에 설치된 전체 순환 팬(도시하지 않음)이 회전될때, 냉기의 유동을 설명한다.First, the flow of cold air will be described when the entire circulation fan (not shown) installed in the freezer compartment is rotated.
상기 전체 순환 팬이 회전하면, 냉장실(15) 각 칸에 형성되고 있는 냉기토출구(13a,13b)에서 냉기가 토출된다. 이렇게 토출된 냉기는 각 칸에 보관중인 음식물을 냉각시킨 후, 냉장실(15) 천정에 형성된 냉기 흡입구(11) 속으로 빨려 들어간다. 이렇게 빨려 들어간 냉기는 냉기공급유로를 통해서 상기 전체 순환 팬에 의해 순환되어 다시 토출구로 토출되는 동작을 반복하게 된다.When the entire circulation fan rotates, cold air is discharged from the cold air discharge ports 13a and 13b formed in each compartment of the refrigerating chamber 15. The cold air discharged in this way cools the food stored in each compartment, and is sucked into the cold air suction port 11 formed in the ceiling of the refrigerating chamber 15. The sucked cold air is repeated by the entire circulation fan through the cold air supply passage and discharged to the discharge port again.
이와 같이, 상기 전체 순환 팬의 회전에 따라서 냉장실 내의 냉기가 순환되면서, 냉장실 내부는 냉기 토출구의 위치와 무관하게 전체적으로 온도 분포가 균일하게 된다.In this way, as the cold air in the refrigerating chamber is circulated according to the rotation of the entire circulation fan, the temperature distribution is uniform throughout the refrigerating chamber regardless of the position of the cold air outlet.
다음은 상기 전체 순환 팬이 정지되고, 냉장실 내부의 순환팬(19)이 회전할때, 냉기 유동을 설명한다.The following describes the cold air flow when the entire circulation fan is stopped and the circulation fan 19 inside the refrigerating compartment rotates.
상기 전체 순환 팬이 정지되면, 상기 냉장실(15) 내부에 장착된 순환팬(19)이 회전한다. 상기 순환팬(19)이 회전되면서, 냉장실 내부의 냉기를 흡입하고, 냉장실 각 칸의 중앙에 형성되고 있는 냉기토출구(17)를 통해서 냉기가 토출된다. 즉, 상기 순환팬(19)은, 냉장실 내부의 정체 중인 냉기를 강제로 순환시키기 위한 구성이다.When the entire circulation fan is stopped, the circulation fan 19 mounted inside the refrigerating chamber 15 rotates. As the circulation fan 19 is rotated, the cold air is sucked in the refrigerating chamber and cold air is discharged through the cold air discharge ports 17 formed at the center of each compartment of the refrigerating chamber. That is, the circulation fan 19 is a configuration for forcibly circulating stagnant cold air in the refrigerating chamber.
이렇게 토출된 냉기는 각 칸에 보관중인 음식물을 냉각시킨 후, 다시 상기 순환팬(19)으로 빨려 들어간다. 이렇게 빨려 들어간 냉기는 냉기공급유로 상의 상기 순환팬에 의해 섞이면서 다시 냉기토출구(17)로 토출되는 동작을 반복하게 된다.The cold air discharged in this way cools the food stored in each compartment and is then sucked back into the circulation fan 19. The cold air sucked in this way is repeated by the circulation fan on the cold air supply passage and discharged to the cold air discharge port 17 again.
이와 같이, 상기 냉장실 순환팬(19)의 회전에 따라서 전체 순환팬이 정지상태일때, 정체될 수 있는 냉장실 내의 냉기를 순환시키게 된다. 따라서 냉장실 내부는 전체 순환 팬의 동작과 무관하게 상기 냉장실 순환팬(19)의 회전으로 전체적으로 온도 분포가 균일하게 된다.As such, when the entire circulation fan is at a standstill according to the rotation of the refrigerating compartment circulation fan 19, the cool air in the refrigerating compartment that can be stagnated is circulated. Therefore, the inside of the refrigerating compartment has a uniform temperature distribution as a whole by the rotation of the refrigerating compartment circulation fan 19 regardless of the operation of the entire circulation fan.
이상에서 설명한 본 발명은 냉동실의 전체 순환 팬 이외에 냉장실에 냉기 순환용 팬을 더 구비한다. 따라서 상기 전체 순환 팬이 정지상태일때, 상기 냉장실의 순환팬을 회전시켜서, 냉장실 내에 정체될 수 있는 냉기를 강제로 순환시키는 것을 기본적인 기술적 사상으로 하고 있다.The present invention described above further includes a cold air circulation fan in the refrigerating compartment in addition to the entire circulation fan of the freezing compartment. Therefore, it is a basic technical idea to rotate the circulation fan of the refrigerating compartment and forcibly circulate the cold air that can be stagnated in the refrigerating compartment when the entire circulation fan is in the stopped state.
그리고 이와 같은 본 발명의 기술적 사상의 범위 내에서, 당업계의 통상의 지식을 가진 자에게 있어서는 다양한 변형이 가능함은 물론이다.And within the scope of the technical idea of the present invention, of course, various modifications are possible to those skilled in the art.
위에서 설명한 본 발명은 다음의 효과를 갖게 된다.The present invention described above has the following effects.
첫째, 냉동실에 전체 순환 팬을 설치하고 있는 냉장실에서, 냉장실에 팬을 구비하는 것에 의해서 상기 전체 순환 팬의 오프 상태에서도 냉장실 내 냉기를 순환시키는 것이 가능하게 된다. 따라서 음식물과 냉기 사이의 열교환이 지속적으로 이루어지면서 음식물의 냉각속도가 빨라지는 잇점이 있다.First, in the refrigerating chamber in which the whole circulation fan is installed in the freezer compartment, by providing the fan in the refrigerating chamber, it is possible to circulate the cold air in the refrigerating compartment even in the off state of the whole circulation fan. Therefore, there is an advantage that the cooling rate of the food is faster as the heat exchange between the food and the cold is made continuously.
둘째, 냉동실 팬이 오프 상태일때, 냉장실 내 냉기가 순환되지 못하고 정체되어서 음식물과의 열교환이 자연대류에 의존하였던 종래와는 달리 냉장실 냉기를 믹싱시켜 순환시키므로서 냉장실 전체 온도 분포가 균일해지는 잇점이 있다.Second, when the freezer compartment fan is off, the cold temperature in the refrigerating compartment is not circulated but stagnant, so that the overall temperature distribution of the refrigerating compartment is uniform by mixing and circulating the refrigerating compartment cold air, unlike in the conventional case in which heat exchange with food is dependent on natural convection. .
셋째, 이러한 점과 더불어, 보관중인 음식물이 보다 장시간동안 신선도를 유지할 수 있으므로서, 소비자에게 제품에 대한 만족도를 높이는 것도 기대할 수 있다.Third, in addition to this point, the food can be kept fresh for a longer time, while also increasing the customer satisfaction with the product can be expected.
