Description
본 발명은 냉동사이클의 증발기에 의해 열교환된 냉기를 냉동실 및 냉장실로 순환시켜 음식물을 냉동/냉장 보관할 수 있도록 하는 냉장고에 관한 것으로서, 더욱 상세하게는 냉기순환을 위한 냉동실팬과 냉장실팬이 각각 장착되는 2팬 적용식 냉장고에 관한 것이다.The present invention relates to a refrigerator which circulates cold air exchanged by an evaporator of a freezing cycle into a freezer compartment and a refrigerating compartment so that food can be frozen / refrigerated, and more specifically, a freezer compartment fan and a refrigerating compartment fan are respectively provided for cold air circulation. It relates to a two fan refrigerator.
일반적으로 냉장고는 각종 음식물을 냉동, 냉장상태로 저장하여 장시간 신선도를 유지시키는 데 사용되는 것으로, 냉동사이클(refrigerating cycle)의 증발기(evaporator)를 음식물 저장공간에 설치하여 직접 열교환을 이루도록 하는 직접 냉각방식과, 그 증발기를 식품 저장공간으로부터 격리된 통로상에 설치하고 증발기를 통해 열교환된 냉기를 팬의 송풍력을 통해 강제로 순환시켜 저장된 음식물을 냉각시키는 간접 냉각방식이 사용되고 있다.Generally, a refrigerator is used to keep various foods in a frozen and refrigerated state to maintain freshness for a long time. A direct cooling method of installing a evaporator of a refrigerating cycle in a food storage space for direct heat exchange. And an indirect cooling method in which the evaporator is installed on a passage separated from the food storage space and the heat exchanged through the evaporator is forced to circulate through the blowing force of the fan to cool the stored food.
여기서, 간접 냉각식 냉장고는 도 1 및 도 2에 도시되는 바와 같이, 중앙부에 횡방향으로 설치된 사절부(103)에 의해 냉동실(110)과 냉장실(120)이 상하로 격리되어 각각의 도어(111)(121)에 의해 개폐되도록 구성되어 있으며, 냉동실(110) 후방에는 냉동사이클의 증발기(157)가 내장되어 열교환시키기 위한 증발기실(113)이 형성되어 있다.1 and 2, the freezing chamber 110 and the refrigerating chamber 120 are vertically isolated by the trimmer 103 installed in the center in the transverse direction, so that each door 111 is inverted. It is configured to open and close by the 121, the evaporator chamber 113 for the heat exchange is formed inside the freezer compartment 110, the evaporator 157 of the refrigerating cycle is built.
그리고, 사절부(103)의 상면부에는 냉동실(110)을 증발기실(113)과 연통시키기 위한 냉동실 귀환덕트(115)가 형성되어 있고, 사절부(103)의 하면부에는 냉장실(120)을 증발기실(113)과 연통시키기 위한 냉장실 귀환덕트(123)가 형성되어 있으며, 증발기실(113)의 상단부에는 냉장실(120)을 연통시키는 냉장실 냉기덕트(125)가 형성되어 있다.In addition, a freezer compartment return duct 115 for communicating the freezer compartment 110 with the evaporator chamber 113 is formed at an upper surface of the trimmer 103, and a refrigerating compartment 120 is provided at the bottom of the trimmer 103. A refrigerating chamber return duct 123 for communicating with the evaporator chamber 113 is formed, and a refrigerating chamber cold air duct 125 for communicating the refrigerating chamber 120 is formed at an upper end of the evaporator chamber 113.
또한, 증발기실(113)의 상단부에는 냉동실 귀환덕트(115)로부터 냉동실(110)의 공기를 흡입하여 증발기실(113)내의 증발기(157)에 의해 열교환된 차가운 냉기를 냉동실 토출구(119)를 통해 냉동실(110)로 토출 순환시키기 위한 냉동실팬(117)이 설치되어 있으며, 그 냉동실팬(117)의 일측에는 냉장실 귀환덕트(123)로부터 냉장실(120)의 공기를 흡입하여 증발기실(113)내의 증발기(157)에 의해 열교환된 차가운 냉기를 냉장실 냉기덕트(125)를 통해 냉장실(120)로 토출 순환시키기 위한 냉장실팬(127)이 설치되어 있다.In addition, the upper end of the evaporator chamber 113 sucks air from the freezer compartment 110 from the freezer compartment return duct 115 and exchanges the cold cold air exchanged by the evaporator 157 in the evaporator chamber 113 through the freezer compartment outlet 119. A freezer compartment fan 117 is provided to circulate the discharge to the freezer compartment 110. One side of the freezer compartment 117 sucks air from the refrigerating compartment 120 from the refrigerating compartment return duct 123 in the evaporator chamber 113. A refrigerating chamber fan 127 is provided for discharging and circulating the cold cold heat exchanged by the evaporator 157 to the refrigerating chamber 120 through the refrigerating chamber cold air duct 125.
따라서, 증발기실(113)내의 증발기(157)에 의해 열교환된 차가운 냉기는 냉동실팬(117)에 의해 냉동실(110)로 토출 공급되고, 그 공급냉기는 냉동실(110)을 일정기간 머무르면서 온도가 상승되면 사절부(103)의 냉동실 귀환덕트(115)로 유입되어 증발기실(113)로 귀환되며, 귀환냉기는 증발기실(113)의 증발기(157)와 열교환을 반복함으로써 냉동실(110)의 음식물을 냉동 보관할 수 있도록 한다.Therefore, the cold cold heat exchanged by the evaporator 157 in the evaporator chamber 113 is discharged and supplied to the freezing chamber 110 by the freezing chamber fan 117, and the supply cold air stays in the freezing chamber 110 for a predetermined period of time to increase in temperature. When the freezing chamber return duct 115 of the trimming section 103 is returned to the evaporator chamber 113, the return cooler repeats heat exchange with the evaporator 157 of the evaporator chamber 113 to remove food from the freezer compartment 110. Allow for freezing.
한편, 증발기실(113)의 증발기(157)에 열교환된 차가운 냉기는 냉장실팬(127)에 의해 냉장실 냉기덕트(125)를 통해 냉장실(120)로 공급되고, 그 공급냉기는 냉장실(120)을 일정기간 머무르면서 온도가 상승되면 사절부(103)의 냉장실 귀환덕트(123)로 유입되어 증발기실(113)로 귀환되면서 증발기실(113)의 증발기(157)와 열교환을 반복함으로써 냉장실(120)의 음식물을 냉장 보관할 수 있도록 한다.On the other hand, the cold cold heat exchanged in the evaporator 157 of the evaporator chamber 113 is supplied to the refrigerating chamber 120 through the refrigerating chamber cold air duct 125 by the refrigerating chamber fan 127, the supply cold air is supplied to the refrigerating chamber 120 If the temperature rises while staying for a certain period of time, the reflow chamber duct 123 of the trimming section 103 flows back into the evaporator chamber 113 while repeating heat exchange with the evaporator 157 of the evaporator chamber 113 to maintain the refrigerating chamber 120. Allow food to be refrigerated.
그런데, 상술한 바와 같이 냉장실팬(127)과 냉동실팬(117)이 장착되는 2팬 적용식 냉장고는 냉동실팬(117)이 냉동실(110)의 후방에 위치된 증발기실(113)에 장착되어 있어 비교적 긴 냉장실 냉기덕트(125)를 통해 냉장실(120)로 토출되는 냉기의 압력손실이 발생하게 되므로 냉장실(120)로의 신속한 냉기공급이 효율적으로 이루어지지 못하게 되는 문제점이 있다.However, as described above, in the two-fan refrigerator having the refrigerator compartment fan 127 and the freezer compartment 117 mounted therein, the freezer compartment 117 is mounted in the evaporator chamber 113 located at the rear of the freezer compartment 110. Since the pressure loss of the cold air discharged into the refrigerating chamber 120 is generated through the relatively long refrigerating chamber cold air duct 125, there is a problem in that the rapid cold air supply to the refrigerating chamber 120 may not be efficiently performed.
또한, 냉동실팬(117)과 냉장실팬(127)이 냉동실(110) 후방에 집중적으로 모여 있으므로 냉동실팬(117)의 장착공간의 협소로 인하여 냉동실(110) 냉기공급이 불균일함은 물론 팬소음의 집중으로 인해 주변환경을 저해시키게 되는 문제점이 있다.In addition, since the freezing compartment fan 117 and the refrigerating compartment fan 127 are concentrated at the rear of the freezing compartment 110, the supply of cold air in the freezing compartment 110 is not uniform due to the narrow space of the freezing compartment fan 117. Due to concentration there is a problem that inhibits the surrounding environment.
이에 따라, 최근 냉장실팬 장착에 따른 냉장실 냉기토출압 손실의 문제점을 해결하기 위한 많은 냉장고 기술들이 연구 개발되고 있는 바, 그 예로서는 대한민국 공개특허공보 제98-084859호에 게시된 냉장고 냉장실팬 설치구조를 들 수 있다.Accordingly, many refrigerator technologies have been researched and developed to solve the problem of cold air discharge pressure loss caused by the installation of the refrigerator compartment fan. For example, the refrigerator refrigerator compartment fan installation structure disclosed in Korean Patent Application Publication No. 98-084859 is disclosed. Can be mentioned.
이러한 공개특허공보 제98-084895호의 냉장고 냉장실팬 설치구조는 냉장실팬을 루버절연물 일측에 삽입 설치되도록 구성함으로써 증발기실내에서 유입된 냉기가 우회유로에 의해 냉기의 진행방향이 역방향으로 바뀜에 따른 냉기 토출속도의 저하를 줄일 수도록 하는 것이나, 냉동실팬과 냉장실팬이 냉동실의 냉동실 후방에 모두 장착됨에 따른 근본적인 문제점 즉 증발기실을 통과하는 냉기가 냉장실팬에 의해 긴통로의 냉장실 냉기덕트를 빠져나가야 함에 따른 압력손실의 문제점 및 팬소음과 장착공간 협소 등에 따른 문제점을 해결할 수는 없다.The refrigerator refrigerating compartment fan installation structure of Korean Patent Application Laid-Open Publication No. 98-084895 is configured to insert the refrigerating compartment fan into one side of the louver insulator so that cold air introduced into the evaporator chamber is discharged by the bypass passage in a reverse direction. In order to reduce the decrease in speed, the fundamental problem is that both the freezer compartment and the refrigerating compartment fan are mounted behind the freezer compartment of the freezer compartment, that is, the cold air passing through the evaporator compartment must exit the refrigerating compartment cold air duct of the main passage by the refrigerator compartment fan. Problems such as pressure loss and fan noise and narrow installation space cannot be solved.
따라서, 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 안출된 것으로, 냉장실팬을 냉장실 내상과 일체로된 벨마우스에 장착함으로써 냉동실의 냉동실 후방에 위치되는 증발기로부터 냉기덕트를 통해 냉장실로 토출되는 냉기의 압력손실을 방지하고 벨마우스의 구조를 간소화할 수 있도록 하는 냉장고를 제공하는 데 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned conventional problems, by mounting the refrigerator compartment fan in the bell mouse integrated with the refrigerator compartment inner phase, the cold air discharged from the evaporator located behind the freezer compartment of the freezer compartment through the cold air duct to the cold compartment The aim is to provide a refrigerator that can prevent pressure loss and simplify the structure of the bell mouse.

이와 같이 구성되는 본 발명의 실시예에 냉장고의 작용을 설명하면 다음과 같다.Referring to the operation of the refrigerator in the embodiment of the present invention configured as described above are as follows.
각 온도센서로부터 검출된 냉동실(10) 및 냉장실(20)의 온도가 설정치보다 높은 상태로 되면, 제어수단은 냉동사이클과 냉동실팬(17) 또는 냉장실팬(27)이 구동시키게 된다.When the temperature of the freezing compartment 10 and the refrigerating compartment 20 detected by each temperature sensor is higher than the set value, the control means drives the freezing cycle and the freezing compartment fan 17 or the refrigerating compartment fan 27.
우선적으로, 냉동사이클의 압축기(51)에서 저온, 저압상태의 가스냉매를 단열 압축하여 고온, 고압가스상태로 변환한 후 응축기(53)로 보내면 응축기(53)에서는 고온, 고압가스상태의 냉매가 외부공기에 의해 냉각, 응축되어 온도:40℃, 압력:9atm의 액체상태가 되며, 이러한 고압, 액체상태의 냉매가 타부분의 관직경에 비해 상대적으로 좁은 팽창밸브(55)를 통과하면서 감압된다. 다음, 팽창밸브(55)에 의해 감압된 냉매가 증발기(57)로 유입되면서 저압상태(0 atm이하)에서 낮은 온도(-30℃)로 증발하면서 증발기실(13)의 열을 흡수하게 된다.First, the compressor 51 of the refrigerating cycle converts the gas refrigerant of low temperature and low pressure state into a high temperature and high pressure gas state, and sends it to the condenser 53. Cooled and condensed by external air, the liquid becomes a liquid at a temperature of 40 ° C. and a pressure of 9 atm, and the high pressure and liquid refrigerant are decompressed while passing through an expansion valve 55 that is relatively narrower than the diameter of the other part. . Next, while the refrigerant depressurized by the expansion valve 55 flows into the evaporator 57, the refrigerant in the evaporator chamber 13 absorbs heat while evaporating to a low temperature (-30 ° C.) at a low pressure (0 atm or less).
예컨대, 냉장실(20)의 온도가 설정치보다 높게 검출됨에 따라 냉장실팬(27)이 구동될 경우, 이때 내상(31)의 요입부(32)와 덕트커버(35)로 이루어진 벨마우스(30)는 팬모터(28)의 양측에서 구동하는 냉장실팬(27)을 통해 연결통로(38)쪽으로는 토출압력을 형성하고 냉장실 냉기덕트(25)쪽으로 흡입력을 형성하게 된다.For example, when the refrigerating chamber fan 27 is driven as the temperature of the refrigerating compartment 20 is detected to be higher than the set value, the bell mouse 30 including the recess 32 and the duct cover 35 of the inner case 31 is Through the refrigerating chamber fan 27 driven from both sides of the fan motor 28 to form a discharge pressure toward the connection passage 38 and a suction force toward the refrigerating chamber cold air duct (25).
이에 따라, 증발기실(13)의 증발기(57)에 열교환된 차가운 냉기는 냉장실 냉기덕트(25)로 유입되면서 벨마우스(30)를 중심으로 작용하는 냉장실팬(27)의 강한 흡입력과 강한 토출력에 의해 압력의 손실없이 연결통로(38) 및 냉장실 토출덕트(24)를 통해 냉장실(20)내로 신속하게 토출 공급된다. 그리고, 냉장실(20) 공급냉기는 냉장실(20)을 일정기간 머무르면서 온도가 상승되면 사절부(3)의 냉장실 귀환덕트(23)로 유입되어 증발기실(13)로 귀환되면서 증발기실(13)의 증발기(57)와 열교환을 반복하게 된다.Accordingly, the cold cold heat exchanged in the evaporator 57 of the evaporator chamber 13 flows into the refrigerator compartment cold air duct 25 and the strong suction force and strong earth output of the refrigerator compartment fan 27 which act on the bell mouse 30. By this, the discharge is rapidly supplied into the refrigerating chamber 20 through the connection passage 38 and the refrigerating chamber discharge duct 24 without losing pressure. When the temperature of the refrigerator compartment 20 is increased while the refrigerator compartment 20 stays for a predetermined period of time, the refrigeration chamber 20 is introduced into the refrigerator compartment return duct 23 of the trimming section 3 and returned to the evaporator chamber 13 so as to return to the evaporator chamber 13. Heat exchange with the evaporator 57 is repeated.
한편, 냉동실(10)의 온도가 설정치보다 높게 검출됨에 따라 구동되는 냉동실팬(17)은 기존의 2팬 적용식 냉장고에서와 같이 그대로 냉동실(10)의 후방에 위치되어 증발기실(13)내의 증발기(57)에 의해 열교환된 차가운 냉기를 냉동실(10)로 토출 공급하고, 또한 냉동실(10)의 공기를 냉동실 귀환덕트(15)를 통해 다시 증발기실(13)로 흡입하여 증발기(57)와 열교환을 반복하게 된다.Meanwhile, as the temperature of the freezer compartment 10 is detected to be higher than the set value, the freezer compartment fan 17 driven is positioned at the rear of the freezer compartment 10 as it is in the conventional two-fan refrigerator, and is located in the evaporator chamber 13. The cold cold air heat exchanged by (57) is discharged and supplied to the freezing compartment (10), and the air of the freezing compartment (10) is sucked back into the evaporator chamber (13) through the freezing chamber return duct (15) to exchange heat with the evaporator (57). Will be repeated.
이상에서 살펴본 바와 같이, 본 발명은 냉장실팬이 냉장실에 설치되어 내상과 일체로된 벨마우스를 형성하므로 냉동실의 냉동실 후방에 위치되는 증발기로부터 냉기순환유로를 통해 냉장실로 토출되는 냉기의 압력손실을 방지하여 냉장효율을 높일 수 있게 되고, 벨마우스의 구조를 간소화하므로 부품수를 줄여 생산원가를 절감하고 냉장고의 폐기물량을 줄일 수 있게 된다.As described above, the present invention prevents the pressure loss of the cold air discharged into the refrigerating chamber through the cold air circulation flow path from the evaporator located behind the freezer compartment of the freezer compartment because the refrigerator compartment fan is installed in the refrigerating chamber to form a bell mouse integral with the internal wound. It is possible to increase the refrigeration efficiency and to simplify the structure of the bell mouse to reduce the number of parts to reduce the production cost and reduce the waste of the refrigerator.
또한, 본 발명은 냉동실팬과 냉장실팬이 서로 다른 공간에 장착되어 있으므로 두 팬이 냉동실 후방에 집중적으로 모여 있게 됨에 따른 장착공간의 협소로 인한 냉기공급이 불균일함을 해소할 수 있게 되며, 팬소음을 효과적으로 대처할 수 있게 되므로 쾌적한 주변환경을 제공할 수 있게 된다.In addition, in the present invention, since the freezer compartment fan and the refrigerating compartment fan are mounted in different spaces, it is possible to solve the uneven supply of cold air due to the narrowing of the mounting space as the two fans are concentrated in the rear of the freezer compartment. Because it can effectively cope with it will be able to provide a pleasant surroundings.
