Abstract
본 고안은 에어커튼을 이용한 냉장고의 냉장실 입체냉각장치에 관한 것으로, 기존에는 냉장고의 냉장실 도어 오픈시에만 약 1분간 구동토록 설치된 냉장고의 냉장실 에어커튼용 팬의 구동은 냉장실 내부에서 감지된 온도변화와는 상관없이 도어의 개폐여부만을 체크하고 있어, 실제적인 냉장실의 고내 온도변황에 적극적으로 대응하지 못하다는 단점이 있었다.The present invention relates to a three-dimensional cooling device of a refrigerator using an air curtain. In the related art, the operation of a fan for a refrigerator's refrigerator in an air curtain of a refrigerator installed to operate for about one minute only when the refrigerator's door is opened is associated with a detected temperature change in the refrigerator compartment. Irrespective of whether the door is opened or closed, there is a drawback that it does not actively respond to changes in the internal temperature of the refrigerator compartment.
이에 이러한 문제점을 해결코자, 에어커튼용 팬에 의한 냉기의 순환유로인 순환덕트의 선단부에 형성된 냉기토출구와 형합되는 덕트구조를 냉장실 도어 내측에 각 포켓부로의 냉기공급구를 갖는 공급덕트를 형성하고, 도어포켓의 소정위치에는 온도센서를 부착하여서 고내의 다른 부위에 설치된 온도센서와의 설정치가 일정 이상이되면 냉장고 도어의 개폐에 상관없이 에어커튼용 팬이 구동되도록 구성된 것이다.In order to solve this problem, a supply duct having a cold air supply port to each pocket part is formed in the refrigerating chamber door with a duct structure which is combined with the cold air discharge port formed at the tip of the circulation duct which is a circulation flow path of cold air by the fan for the air curtain. In addition, by attaching a temperature sensor at a predetermined position of the door pocket, if the set value with the temperature sensor installed in other parts of the refrigerator is more than a predetermined level, the air curtain fan is configured to be driven regardless of opening and closing of the refrigerator door.
Description
본 고안은 에어커튼을 이용한 냉장고의 냉장실 입체냉각장치에 관한 것으로, 보다 상세하게는 냉장고의 고내 온도변황에 따라 도어의 개폐와 상관없이 냉각장치가 구동되어 고내가 냉각될 수 있도록 한 냉장고의 냉장실 입체냉각장치에 관한 것이다.The present invention relates to a three-dimensional cooling device of a refrigerator using an air curtain, and more particularly, to a refrigerator's three-dimensional refrigerator that allows the inside of the refrigerator to be cooled by driving a cooling device regardless of opening or closing of a door according to a temperature change in the refrigerator. It relates to a cooling device.
일반적으로 사용되고 있는 냉장고의 냉각방식은 2개의 팬을 이용하여 증발기로부터 발생한 냉기를 내상의 후면에 형성된 메인덕트 및 그 양측면에 형성된 측면덕트를 통하여 냉장고 내상의 3면에서 냉기가 토출되는 구조를 이루고 있었다.In general, the cooling method of the refrigerator has a structure in which cold air from the evaporator is discharged from three sides of the inside of the refrigerator through the main duct formed on the rear side of the inner box and the side ducts formed on both sides thereof using two fans. .
그리고, 에어커튼을 채용한 기종의 경우는 도시된 도 1과 같이, 냉장실(R) 상부 즉, 사절부(40) 하부면을 따라 형성된 순환덕트(20)와, 순환덕트(20)의 후부에 설치된 에어커튼용 팬(30)인 크로스 플로우 팬(cross flow fan)에 의하여 도어 오픈시에만 에어커튼용 팬(30)이 구동되어 일정시간동안 냉장실 상단의 순환덕트(20) 선단인 냉기토출구(22)를 통하여 고내로 공급되어 고내를 교반시키게 된다.And, in the case of the model employing the air curtain, as shown in Figure 1, the upper portion of the refrigerating chamber (R), that is, the circulation duct 20 formed along the lower surface of the trimming portion 40, and the rear portion of the circulation duct 20 The air curtain fan 30 is driven only when the door is opened by a cross flow fan, which is an installed air curtain fan 30, for a predetermined time. The cold air discharge port 22, which is the tip of the circulation duct 20 at the top of the refrigerating chamber, is opened. It is fed into the chamber through) to stir the interior.
그런데, 이러한 에어커튼 방식의 냉각에도 불구하고 도어개방시 외부의 온기와 단시간에 가장 많이 접촉되며 도어가 닫혔을 경우에도 가스켓의 밀폐구조를 통하여 냉기가 누설되므로 도어부는 흔히 에드 존(dead zone)이라 불리어 왔다. 그러므로 고내 냉기손실이 가장 많은 부위인 도어포켓부는 이 부위를 직접 냉각시키기 위하여 공급되는 장치가 없어 보관중인 식품을 신선하게 장기간 보관키 어려운 문제가 있어 왔다.However, despite the air curtain type cooling, the door part is often called a dead zone because the air is leaked through the sealing structure of the gasket even when the door is closed. It has been called. Therefore, there is a problem that it is difficult to store the food stored fresh for a long time because there is no device to directly cool the area of the door pocket part that is the most cold air loss.
따라서, 이를 극복하고자 가스켓의 구조개선이나, 우레탄 발포시의 일체발포 구조로의 개선 등에 대하여 많은 고안이 있었으나 구체적으로 실체화 되어지지 않았었다.Therefore, in order to overcome this, there have been many devises for structural improvement of the gasket, improvement of the integral foam structure during urethane foaming, but have not been specifically realized.
또한, 냉장실 에어커튼 냉각방식이 도어 오픈시에만 소정시간 동안 에어커튼용 팬(30)을 동작시키도록 국한되어 있어서 전반적인 냉장실의 균일한 냉각성능면에서는 극히 미약하다는 단점이 있어 왔다.In addition, since the refrigerator air curtain cooling method is limited to operate the air curtain fan 30 for a predetermined time only when the door is opened, there has been a disadvantage in that the overall cooling chamber is uniformly weak in terms of uniform cooling performance.
본 고안은 상술한 바와 같은 제반 문제점을 감안하여 이를 해소하고자 안출된 것으로, 냉장고 도어의 오픈에 상관없이 도오포켓부에 분포되는 온도범위와, 고내에 분포된 냉기온도차이의 정도에 따라 에어커튼용 팬이 작동될 수 있도록 한 냉장고의 냉장실 입체냉각장치의 제공을 그 기술적 과제로 한다.The present invention has been devised to solve the above problems in consideration of the above-mentioned problems, and is used for air curtains according to the temperature range distributed in the doe pocket part and the degree of cold air temperature difference distributed in the refrigerator regardless of the opening of the refrigerator door. It is a technical problem to provide a refrigerator's three-dimensional cooling device of a refrigerator in which a fan can be operated.

It is in communication with the cold air outlet, and the lower part is opened to each door pocket of the refrigerating compartment door, and a plurality of door air supply ducts for the cold air are formed inside the door, and the pocket is installed in the refrigerating compartment door even when the door is closed. By comparing the signal of the negative temperature sensor and the signal of the high temperature sensor installed inside the refrigerating chamber, the microcomputer selectively drives the fan for the air curtain, and the cold air supplied through the cold air supply duct for the air curtain is supplied to each door pocket for a predetermined temperature difference. It is characterized by.
이하에서는, 본 고안의 바람직한 일 실시예를 첨부한 도면을 따라 보다 상세히 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention will be described in more detail.
첨부한 도 2는 본 고안에 따른 냉기 공급덕트(50)가 순환덕트(20)에 형합되어 있는 모양을 개략적으로 도시한 측단면도이고, 도 3은 본 고안을 설명하기 위하여 일부절결한 부분 사시도이다.2 is a side cross-sectional view schematically showing a shape in which the cold air supply duct 50 according to the present invention is incorporated into the circulation duct 20, and FIG. 3 is a partially perspective view partially cut to explain the present invention. .
본 고안은 도 2 내지 도 3에서 도시한 바와 같이, 에어커튼을 채택한 기종에서 사용되고 있는 크로스 플로우팬을 이용하여 냉장고 내부의 4면에서 냉기를 토출하게 해주는 4면 입체냉각방식에 관한 것으로, 기존의 냉장고 냉장실(R) 에어커튼 구조에 도어포켓(12)부로 냉기를 공급가능토록 한 냉기유로, 즉 냉기 공급덕트(50)와, 도어포켓부(12) 온도변화 감지를 위한 포켓부온도센서(48)가 추가된 구조이다.2 to 3, the present invention relates to a four-sided three-dimensional cooling method for discharging the cold air from the four sides of the inside of the refrigerator using a cross flow fan used in the model adopting the air curtain, Cold air flow path for supplying cold air to the door pocket 12 part in the refrigerator curtain compartment air curtain structure, that is, the cold air supply duct 50 and the pocket part temperature sensor 48 for detecting the temperature change of the door pocket part 12. ) Is added.
또한, 에어커튼용 팬(30)에 의한 냉기가 순환덕트(20)를 타고 냉기토출구(22)로 토출될 때에 토출구(22)와 공급덕트(50)간에는 형합구조를 이루어 포켓부(12)로의 냉기공급유로를 형성하여 냉장고의 냉장실 도어포켓부로 다수의 덕트를 타고 각 포켓(12)들 사이사이로 냉기가 토출되도록 구성한 것이다.In addition, when the cold air from the air curtain fan 30 is discharged to the cold air discharge port 22 by the circulation duct 20, a discharge structure is formed between the discharge port 22 and the supply duct 50 to the pocket portion 12. The cold air supply passage is formed so that cold air is discharged between the pockets 12 through a plurality of ducts through the refrigerator compartment door pocket part of the refrigerator.
한편, 도어포켓(12) 상부 일측에는 포켓부온도센서(48)을 추가 설치하며, 고내온도센서(38)가 송출하는 감지신호와 포켓부온도센서(48)가 송출하는 감지신호를 제어부가 판단하여 에어커튼용 팬(30)을 구동제어토록 각 온도센서(38)(48)는 제어부에 연결되어 있다.On the other hand, the upper part of the door pocket 12 is further provided with a pocket temperature sensor 48, the control unit determines the detection signal sent by the high temperature sensor 38 and the detection signal sent by the pocket temperature sensor 48. Thus, the temperature sensors 38 and 48 are connected to the control unit so as to drive the air curtain fan 30.
이러한 구성으로 이루어진 본 고안에 따른 에어커튼을 이용한 냉장고의 냉장실 입체냉각장치는, 냉장실 도어(10)가 닫혔을 경우 고내등 주위에 부착되어 있는 고내온도센서(38)와 도어(10)에 부착되어 있는 포켓부온도센서(48)에 의해서 측정되어진 온도차이가 설정온도차 이상이 되면 에어커튼용 팬(30)인 크로스 플로우 팬이 작동을 시작하게 되고, 이미 냉장실 도어(10)는 닫혀 있으므로 자연스럽게 도어포켓부(12)로 향하도록 설계된 냉기 공급덕트(50)의 선단부와 순환덕트(20)의 냉기토출구(22)간에는 형합구조를 이루어 순환되는 냉기를 공급덕트(50)의 냉기공급구(62)를 통하여 도어포켓부(12)로 토출 유도토록 작용하는 것이다.The refrigerator compartment three-dimensional cooling device of the refrigerator using the air curtain according to the present invention having such a configuration is attached to the high temperature sensor 38 and the door 10 attached to the interior of the refrigerator when the refrigerator door 10 is closed. When the temperature difference measured by the pocket part temperature sensor 48 is equal to or higher than the set temperature difference, the cross flow fan, which is the fan 30 for the air curtain, starts to operate, and since the refrigerating compartment door 10 is closed, the door pocket part is naturally Between the tip of the cold air supply duct 50, which is designed to face 12, and the cold air discharge port 22 of the circulation duct 20, the cold air circulated in a structure is formed through the cold air supply port 62 of the supply duct 50. It acts to induce discharge to the door pocket portion 12.
즉, 공급덕트(50)의 선단부에 형성된 끼움부(52)가 순환덕트(20)의 냉기토출구(22) 인접부위에 돌설된 고정부(54)로 삽입 고정되는 것이다.That is, the fitting portion 52 formed at the distal end of the supply duct 50 is inserted into and fixed to the fixing portion 54 protruding in the vicinity of the cold air discharge port 22 of the circulation duct 20.
반면, 냉장실 도어(10)가 오픈되면, 공급덕트(50)와 순환덕트(20)간의 형합구조는 해제되고, 제어부의 통제에 따라 자동으로 에어커튼용 팬(30)이 구동되면서 냉장실(R) 에어커튼을 행하게 된다.On the other hand, when the refrigerating compartment door 10 is opened, the mating structure between the supply duct 50 and the circulation duct 20 is released, and the air curtain fan 30 is automatically driven under the control of the control unit while the refrigerating compartment R The air curtain is performed.
그러므로, 냉장고의 냉장실 도어(10)가 개방될 때에만 에어커튼이 진행되는 것이 아니라, 도어(10)가 폐쇄된 상태에서도 포켓부온도센서(48)와 고내온도센서(38)간의 온도차이가 규정치 이상이 되면 제어부의 제어신호에 의해 에어커튼용 팬(30)이 구동되면서 냉기를 도어포켓부(12)로 공급하게 되어 고내가 입체냉각되면서 단시간에 고내 정온화를 이룰 수 있게 되는 것이다.Therefore, the air curtain does not proceed only when the refrigerating compartment door 10 of the refrigerator is opened, and the temperature difference between the pocket temperature sensor 48 and the high temperature sensor 38 is defined even when the door 10 is closed. In this case, the air curtain fan 30 is driven by the control signal of the controller to supply the cool air to the door pocket part 12 so that the inside of the refrigerator is cooled three-dimensionally so that the inside temperature of the refrigerator can be achieved in a short time.
이상에서 살펴 본 바와 같이, 본 고안에 따른 에어커튼을 이용한 냉장고의 냉장실 입체냉각장치는, 냉장실 도어포켓부까지 직접 냉기가 토출되는 4면 입체냉각이 이루어지므로 고내온도 상승의 가장 취약부분인 도어부의 온도상승을 억제하며, 도어 오픈 후에 일정시간동안만 동작하고 있는 종래의 에어커튼용 팬의 구동을 적극적으로 활용할 수 있으므로 궁극적으로는 냉장고 내부의 온도구배를 균일하게하여 냉장고의 주목적인 냉각성능을 향상시키는 효과를 제공하는 것이다.As described above, the refrigerator compartment three-dimensional cooling device of the refrigerator using the air curtain according to the present invention, since the four-sided three-dimensional cooling is discharged directly to the refrigerator compartment door pocket portion is made of the door portion which is the most vulnerable part of the high temperature rise It can suppress the temperature rise and actively use the drive of the conventional air curtain fan that operates only for a certain time after the door is opened, and ultimately improves the cooling performance of the refrigerator by uniformizing the temperature gradient inside the refrigerator. To provide an effect.
