Description

냉장고의 냉기 순환구조Cold air circulation structure of the refrigerator

본 발명은 냉장고에 관한 것으로서, 더욱 상세하게는 캐비닛의 냉동실 및 냉장실 내부로 순환되는 냉기 순화구조에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to a cold air purifying structure circulated into a freezer compartment and a refrigerating compartment of a cabinet.

일반적으로 냉장고는 도 1에 도시된 바와 같이, 캐비닛(10)의 중간 부위에 설치된 중간 칸막이(11)를 통해 냉동실(20)과 냉장실(30)로 구획 형성되며, 이 각각의 냉동실(20)과 냉장실(30)은 냉기의 외부 유출을 방지하기 위한 상,하부 도어(40,50)를 통해 선택적으로 개폐되도록 구성되어 있다.In general, as shown in FIG. 1, the refrigerator is partitioned into a freezer compartment 20 and a refrigerator compartment 30 through an intermediate partition 11 installed at an intermediate portion of the cabinet 10, and each of the freezer compartments 20 and The refrigerating chamber 30 is configured to be selectively opened and closed through upper and lower doors 40 and 50 to prevent the outflow of cold air.

또한 냉동실(20)과 냉장실(30)의 내부에는 식품류의 수납이 용이하도록 다수의 선반(60)이 마련되며, 각 도어(40,50)측에도 식품류의 수납을 위한 포켓(pocket;70)이 다수 마련되어 있다.In addition, a plurality of shelves 60 are provided in the freezer compartment 20 and the refrigerating compartment 30 to facilitate food storage, and a plurality of pockets 70 for storing foodstuffs are also provided at the doors 40 and 50. It is prepared.

이와같은 구성을 갖는 냉장고의 냉기 순환구조를 보면, 도 2에 도시된 바와 같이, 캐비닛(10) 내측면에 위치된 증발기(1) 주변부의 냉기는 도시되지 않은 송풍팬에 의해 캐비닛(10)의 내측면에 마련된 덕트(duct;2)를 통해 화살표로 도시된 바와 같은 방향으로 냉동실(20) 및 냉장실(30) 내부로 순환되게 된다.Referring to the cold air circulation structure of the refrigerator having such a configuration, as shown in FIG. 2, the cold air around the evaporator 1 located on the inner side of the cabinet 10 is connected to the cabinet 10 by an unshown blower fan. It is circulated into the freezer compartment 20 and the refrigerating compartment 30 in the direction as shown by the arrow through a duct (2) provided on the inner side.

그러나 이와같은 일반적인 냉장고의 냉기 순환구조에 있어서는, 도어(40,50)측의 포켓(70)에 수납된 식품류는 신속한 냉동 및 장시간의 신서도 유지가 곤란한 문제점이 내재되어 있다.However, in such a cold air circulation structure of a general refrigerator, foods stored in the pockets 70 on the doors 40 and 50 side have a problem that it is difficult to quickly freeze and maintain long-term new books.

이는, 캐비닛(10) 내부를 순환하는 냉기가 도어(40,50)측의 포켓(70)에 고루 순환되지 못하기 때문이다. 즉, 냉기가 냉동실(20)과 냉장실(30)의 내부를 기준으로 순환되도록 덕트(2)를 형성한 것이기 때문이다.This is because cold air circulating in the cabinet 10 cannot be circulated evenly in the pocket 70 on the doors 40 and 50 side. That is, because the duct 2 is formed so that the cold air is circulated based on the interior of the freezing chamber 20 and the refrigerating chamber 30.

이와같은 문제점은 특히 도어(40,50)측에 무거운 하중의 식품류를 보관함에 있어서는, 즉, 큰 음료수병 등을 보관함에 있어서 신속하게 냉각시킬 수 없게되어 더욱 심각하게 대두된다 할 것이다.This problem is particularly serious in storing heavy foods on the doors (40, 50), that is, in the storage of large beverage bottles, such as can not be quickly cooled.

본 발명은 이와같은 종래의 문제점을 해결하기 위하여 창출된 것으로서, 냉기의 순환을 캐비닛의 냉동실 및 냉장실뿐만 아니라 도어측에 까지 고루 순환시킬수 있어 특히 무거운 하중의 식품류의 신선한 보관을 도모할 수 있는 냉장고의 냉기 순환구조를 제공함에 그 목적이 있다.The present invention was created in order to solve such a conventional problem, and the circulation of cold air can be circulated evenly to the door side as well as the freezer compartment and the refrigerating compartment of the cabinet, and particularly of the refrigerator capable of fresh storage of heavy loads of foodstuffs. The purpose is to provide a cold air circulation structure.

이와같은 목적을 달성하기 위하여 본 고안에 따른 냉장고의 냉기 순환구조는, 그 중간 부위에 설치되는 중간 칸막이를 통해 냉동실과 냉장실로 구획 형성되며, 내면에는 냉동실과 냉장실 내측으로 냉기를 유입시키는 덕트가 형성된 캐비닛과, 상기 캐비닛상에 힌지 결합되어 냉동실과 냉장실을 선택적으로 개폐시키며, 내측면에는 사익 캐비닛의 덕트로 부터의 냉기가 유입되도록 보조 덕트가 폭 방향으로 형성되고, 전면에는 보조 덕트로 유입되 냉기가 토출되도록 소정폭의 토출홈이 형성된 상,하부 도어와; 상기 토출홈과 인접된 상,하부 도어의 각 전면으로부터 일체로 연장 형성되는 수납 돌기와; 상기 상,하부 도어의 수납돌기상에 마련되며, 토출홈을 통해 토출되는 냉기의 토출량을 조절하는 토출량 조절수단;을 포함하여 된 것을 그 특징으로 한다.In order to achieve the above object, the cold air circulation structure of the refrigerator according to the present invention is partitioned into a freezer compartment and a refrigerating compartment through an intermediate partition installed at an intermediate portion thereof, and an inner surface of which a duct is formed to introduce cold air into the freezer compartment and the refrigerating compartment. The cabinet is hinged on the cabinet to selectively open and close the freezer compartment and the refrigerating compartment.

이와같은 본 발명의 특징적인 구성 및 이에따른 작용효과는 후술하는 첨부된 도면을 참조한 발명의 상세한 설명을 통해 더욱 명확해 질 것이다.Such a characteristic configuration and the resulting effects of the present invention will become more apparent from the following detailed description of the invention with reference to the accompanying drawings.

도 3 및 도 4는 본 발명에 따른 냉기 순환구조를 보인 평단면도 및 측단면도이다. 그리고 이하에서는 도 1 및 도 2를 참조하여 설명한다.3 and 4 are a plan sectional view and a side sectional view showing a cold air circulation structure according to the present invention. Hereinafter, a description will be given with reference to FIGS. 1 and 2.

캐비닛(10)의 중간 부위에 설치된 중간 칸막이(11)를 통해 냉동실(20)과 냉장실(30)로 구획 형성되며, 이 각각의 냉동실(20)과 냉장실(30)은 냉기의 외부 유출을 방지하기 위한 상,하부 도어(40,50)를 통해 선택적으로 개폐되도록 구성되어 있다.The freezer compartment 20 and the refrigerating compartment 30 are partitioned through an intermediate partition 11 installed at an intermediate portion of the cabinet 10, and each of the freezer compartment 20 and the refrigerating compartment 30 is configured to prevent the outflow of cold air. It is configured to selectively open and close through the upper and lower doors (40, 50).

또한 냉동실(20)과 냉장실(30)의 내부에는 식품류의 수납이 용이하도록 다수의 선반(60)이 마련되며, 도어(40,50)측에는 식품류의 수남을 위한 수납돌기(41,51)가 일체로 다수 연장 형성된다.In addition, a plurality of shelves 60 are provided in the freezer compartment 20 and the refrigerating compartment 30 to facilitate food storage, and the receiving protrusions 41 and 51 are integral to the doors 40 and 50 for males and females. It is formed by a plurality of extensions.

이때 캐비닛(10) 내측면에 위치된 증발기(1) 주변부의 냉기를 냉동실(20) 및 냉장실(30)로 순환시키기 위한 덕트(duct;2)는 도시되지 않은 송풍팬에 의해 캐비닛(10)의 내측면에 마련된 덕트(duct;2)를 통해 화살표로 도시된 바와 같은 방향으로 냉동실(20) 및 냉장실(30) 내부로 순환되게 된다.At this time, the duct (2) for circulating the cold air around the evaporator 1 located on the inner surface of the cabinet 10 to the freezing chamber 20 and the refrigerating chamber 30 is connected to the cabinet 10 by a blower fan (not shown). It is circulated into the freezer compartment 20 and the refrigerating compartment 30 in the direction as shown by the arrow through a duct (2) provided on the inner side.

한편, 전술한 상,하부 도어(40,50)의 내측면에는 전술한 캐비닛(10)의 덕트(2)로부터 토출되는 냉기중의 일부를 유입하기 위한 보조 덕트(2')가 폭방향을 따라 길게 형성되며, 특히 그 전면에는 보조 덕트(2')로 유입된 냉기를 전면을 향해 토출하기 위한 토출홈(40a)이 형성된다.On the other hand, the auxiliary duct 2 'for introducing a part of the cold air discharged from the duct 2 of the cabinet 10 described above in the width direction on the inner surface of the upper and lower doors 40 and 50 described above. It is formed long, and in particular, a discharge groove 40a for discharging cold air introduced into the auxiliary duct 2 'toward the front surface is formed.

이때 토출홈(40a)은 토출량 조절수단을 통해 그 폭이 즉, 냉기 토출량이 조절되어 진다.At this time, the width of the discharge groove 40a is adjusted through the discharge amount adjusting means, that is, the amount of cold air discharged.

이와같은 토출량 조절수단의 구성을 보면 크게 수납돌기(41,51)에 안착되는 포케(pocket;7)과, 스프링(s)으로 대별된다.Looking at the configuration of the discharge amount adjusting means as described above are largely divided into a pocket (7) and a spring (s) seated on the receiving projections (41, 51).

포켓(70)은, 바닥판(71)과, 이 바닥판(71)의 일측면으로부터 연장 형성되며, 수납되는 식품류가 전면으로 탈락되는 것을 방지하기 위한 걸림판(72)과, 바닥판(71)의타측면으로부터 연장 형성되어 전술한 토출홈(40a)의 개방폭을 조절하는 조절판(73)으로 이루어진다.The pocket 70 extends from one side of the bottom plate 71, the bottom plate 71, a stopping plate 72 for preventing the foods to be stored from dropping to the front, and the bottom plate 71. Is formed extending from the other side of the control panel 73 for adjusting the opening width of the above-described discharge groove (40a).

한펴, 조절판(73)은 걸림판(72)의 연장 길이에 비하여 상대적으로 짧게 연장 형성되도록 함이 바람직하다. 이는, 식품류의 수납이 용이하도록 하기 위함은 물론이고, 특히 토출홈(40a)의 폭을 적절히 조절하기 위함이다.In addition, it is preferable that the adjustment plate 73 is formed to extend relatively short compared to the extension length of the locking plate 72. This is, of course, to facilitate the storage of foodstuffs, and in particular to properly adjust the width of the discharge groove (40a).

이때 특히 조절판(73)의 초기 위치는 토출홈(40a)을 소정폭 만큼 밀폐시킨 상태로 연장 형성되어야 할 것이다.In this case, in particular, the initial position of the control plate 73 should be formed to extend in a state in which the discharge groove 40a is sealed by a predetermined width.

한편, 스프링(s)은 포켓(70)의 하면과 즉, 바닥판(71) 하면과 수납돌기(41,51)상면사이에 개재되는 것으로서, 포켓(70)을 상방으로 탄성지지하는 역할을 한다.On the other hand, the spring (s) is interposed between the lower surface of the pocket 70, that is, between the lower surface of the bottom plate 71 and the upper surface of the receiving projections (41, 51), and serves to elastically support the pocket 70 upwards. .

이와같은 구성을 갖는 본 발명은, 냉기가 도시되지 않은 송풍팬에 의해 순환되는 과정이서 캐비닛(10)의 덕트 (2)로부터 토출된 냉기중의 일부가 도 3에 도시된 바와 같이 도어(40,50)상에 형성된 보조 덕트(2')내로 유입되고 동시에 토출홈(40a)을 통해 수납돌기(41,51)상에 안착된 포켓(70)으로 토출됨으로써 이 포켓(70)상에 수납된 식품류를 냉동시키거나 또는 신속하게 냉장시키게 된다.According to the present invention having such a configuration, a part of the cold air discharged from the duct 2 of the cabinet 10 is a process in which cold air is circulated by a blower fan (not shown), as shown in FIG. Foods stored on the pocket 70 by flowing into the auxiliary duct 2 'formed on the 50 and simultaneously being discharged to the pocket 70 seated on the receiving projections 41 and 51 through the discharge groove 40a. Can be frozen or refrigerated quickly.

이때 특히 포켓(70)상에 무거운 하중의 식품류가 즉, 음료수 병등이 수납되게 되면, 스프링(s)에 의해 탄성지지된 포켓(70)이 수납돌기(41,51)를 향해 이송되게 되고, 즉, 하방으로 이송되게 되고, 이에의해 조절판(73)에 의해 어느정도 밀폐된 상태를 유지하고 있던 토출홈(40a)의 개방폭이 크게 조절되게 된다. 따라서 토출홈(40a)을 통해 토출되는 냉기의 토출량의 크게 할 수 있게되어 신속하게 냉각(냉장)시킬 수 있게된다.At this time, particularly when heavy loads of food are stored on the pocket 70, that is, beverage bottles and the like, the pocket 70 elastically supported by the spring s is transferred toward the receiving protrusions 41 and 51, that is, , And is transported downward, whereby the opening width of the discharge groove 40a, which has been kept somewhat closed by the control plate 73, is greatly adjusted. Therefore, the discharge amount of the cold air discharged through the discharge groove 40a can be increased, so that the cooling (refrigeration) can be quickly performed.

상술한 바와 같이 본 발명에 따른 냉장고의 냉기 순화구조에 의하며, 냉기의 순환이 덕트를 통해 냉종실과 냉장실로 유입되어 순화되는 것은 물론이고, 도어측의 보조 덕트를 통해 포켓상으로 토출되어 순환되는 것이기 때문에 좀더 빠른 식품류의 냉동 및 냉장 상태를 도모할 수 있게 되며, 특히 하중이 무거운 식품류의 냉동 및 냉장을 신속하게 행할 수 있게된다. 따라서 이를 채용한 냉장고의 신뢰성 및 만족감을 더 한층 충족시킬 수 있는 효과가 있다.As described above, according to the cold air purifying structure of the refrigerator according to the present invention, the circulation of cold air flows into the cold seed chamber and the refrigerating chamber through the duct and is purified, as well as discharged to the pocket through the auxiliary duct on the door side. In this way, the freezing and refrigeration of food items can be achieved faster, and in particular, the freezing and refrigeration of heavy food items can be performed quickly. Therefore, there is an effect that can further satisfy the reliability and satisfaction of the refrigerator employing it.
