본 고안은 냉장고의 증발기로부터 열교환되어 냉동실측으로 공급되는 냉기를 냉동실의 하부측으로도 공급되게 하여 냉동실의 선반에 많은 식품을 보관할 경우에도 냉기를 냉동실내에 골고루 공급되게 하는 냉장고의 냉기흐름 제어장치에 있어서, 냉동실로 공급되는 냉기의 흐름을 냉동실의 선반을 이용하여 제어토록 하므로서 작동이 정확하게 이루어지도록 하고, 조작이 편리하도록 한 냉장고의 냉기흐름 제어장치에 관한 것이다.The present invention provides a cold air flow control device of the refrigerator to heat the cold from the evaporator of the refrigerator is supplied to the freezer compartment also to the lower side of the freezer compartment so that even when the food is stored on the shelf of the freezer evenly cool air in the freezer compartment, By controlling the flow of cold air supplied to the freezing chamber using the shelves of the freezer to ensure the operation is made precisely, and to a cold air flow control device for convenient operation.
일반적으로 냉장고의 구성을 보면 제1도에서와 같이 냉장고 본체(1)내의 상, 하단에 냉동실(2)과 냉장실(3)이 각각 구비되어 있고 이들의 중앙부에는 증발기(4)와 그 직후방에 송풍장치(5)가 구비되어 있으며, 그리고 본체(1) 하방에는 응축기(6)와 압축기(7)가 구성되어 있다.In general, as shown in FIG. 1, the freezer compartment 2 and the refrigerating compartment 3 are provided at the upper and lower ends of the refrigerator main body 1, respectively, as shown in FIG. The blower 5 is provided, and the condenser 6 and the compressor 7 are comprised below the main body 1. As shown in FIG.
따라서 냉동사이클에 의해 증발기(4)에서 열교환된 냉기를 송풍장치(5)의 송풍력으로 상, 하측 냉동실(2)과 냉장실(3)측으로 공급되게 하여 냉동실(2)에서는 식품을 냉동상태로 보관케하고 냉장실(3)에서는 식품을 저온상태로 냉장 보관시키게 하고 있는 것이었다.Therefore, the cold air heat-exchanged in the evaporator (4) by the refrigeration cycle is supplied to the upper and lower freezer compartment (2) and the refrigerating compartment (3) side by the blowing force of the blower (5) to store food in the freezer compartment (2) in the frozen state In the refrigerator compartment (3), food was refrigerated at low temperature.
이러한 냉장고의 구성에 있어 냉기의 흐름을 더욱 상세히 설명하면 냉장실(3)측으로는 소정 설정치 온도 약 3℃를 유지시키기 위하여 냉기를 간헐적으로 공급 및 차단시켜야만 하는 것으로서 이는 증발기(4)가 내장된 분리벽(8)내의 열교환실(9)과 냉장실(3)의 사이를 냉기통로(10)로 연결하고 이 냉기통로(10)에 개폐되는 댐퍼(11)가 구비되어 감지되는 온도에 따라 개폐 되도록 구성되어 있다.In the configuration of such a refrigerator, the flow of cold air will be described in more detail. In order to maintain a predetermined set temperature of about 3 ° C. on the side of the refrigerating chamber 3, cold air must be intermittently supplied and cut off, which is a partition wall in which the evaporator 4 is incorporated. (8) is provided between the heat exchange chamber 9 and the refrigerating chamber 3 in the cold air passage 10 and a damper 11 which is opened and closed in the cold air passage 10 to open and close according to the sensed temperature. have.
또한, 냉동실(2)측으로 공급되는 냉기는 열교환실(9)과 연결되는 냉기통로(12)를 거쳐 냉동실(2)의 상단냉기 분출구(13)를 통하여 냉동실(2)내로 공급되는 것이었다.In addition, the cold air supplied to the freezing chamber 2 side was supplied into the freezing chamber 2 through the cold air passage 12 connected to the heat exchange chamber 9 through the upper end cold air outlet 13 of the freezing chamber 2.
그런데, 냉동실(2)측으로 공급되는 냉기는 냉기통로(12)를 통하여 냉동실(2)의 상단부에 구비된 냉기분출구(13)로 공급되므로서 냉동실(2)의 선반(14)에 보관하고자 하는 식품이 많을 경우 선반(14) 하단부에는 냉기가 차단되어 냉동실(2) 하단부의 보관식품은 냉동이 원활히 되지 않는 문제점이 있는 것이었다.By the way, the cold air supplied to the freezer compartment 2 side is supplied to the cold air jet port 13 provided in the upper end of the freezer compartment 2 through the cold air passage 12, and the food to be stored in the shelf 14 of the freezer compartment 2. If there are a lot of cold air is blocked at the bottom of the shelf 14, the food stored at the bottom of the freezer compartment 2 was a problem that the freezing is not smooth.
따라서, 이러한 문제점을 해결코자 종래에도 냉동실(2)측으로 공급되는 냉기를 선택적으로 선반(14) 하단부측에 공급하는 장치가 알려져 있었다.Therefore, in order to solve this problem, a device for selectively supplying the cold air supplied to the freezer compartment 2 side to the lower end side of the shelf 14 has been known.
즉, 냉동실(2)의 후벽면 하단부에 냉기분출구를 형성하여 냉기통로와 연통되게 하고, 상기 냉기 분출구에는 회동자재되는 차폐판을 구비함과 아울러 이의 차폐판을 냉동실내의 측벽으로 설치되는 작동레버의 조절작동에 의해 차폐판이 냉기분출구를 개폐토록 구성된 것이었다. (공개번호 87-5608호 참조)That is, the cold air outlet is formed at the lower end of the rear wall surface of the freezer compartment 2 so as to communicate with the cold air passage, and the cold air outlet is provided with a shielding plate which is rotated and the shielding plate of the operation lever is installed as a side wall in the freezer compartment. The control plate was configured to open and close the cold air outlet by the adjustment operation. (See Publication No. 87-5608)
그러나, 이같은 종래의 구성은 작동레버의 조절작동에 의해 냉기통로의 냉기흐름이 제어되는 것으로서 그 구성이 복잡하고, 또한 부품수가 많아 설치작업이 어려울뿐 아니라 작동레버가 냉동실(2)내로 돌출 설치되므로서 냉동실(2)의 내용적을 줄이게 됨과 아울러 냉동실(2)에 식품을 적재시 작동레버를 건드리게 되어 오작동이 발생하게 되는 문제점도 있는 것이었다.However, such a conventional configuration is that the cold air flow of the cold passage is controlled by the adjusting operation of the operating lever, and its configuration is complicated, and the number of parts is not only difficult to install, but also the operating lever protrudes into the freezer compartment 2. In addition to reducing the contents of the freezer compartment (2), there was also a problem that a malfunction occurs by touching the operation lever when loading the food in the freezer compartment (2).
또 다른 방식은 냉동실 하단에 제빙실을 형성하여 급속으로 제빙을 하기 위한 장치로(공개번호 89-11221호 참조) 상기 제빙실의 후방 벽면에 냉기유입구를 형성하고 그 상방에 개폐판을 회동자재토록 설치하여 제빙용기의 작동편이 개폐판을 밀음작동에 의해 냉기유입구를 개폐토록 구성된 것이었다.Another method is to form an ice making chamber at the bottom of the freezing chamber to rapidly defrost (see Publication No. 89-11221). A cold air inlet is formed on the rear wall of the ice making chamber, and an opening and closing plate is rotated thereon. The installation piece of the ice making container was configured to open and close the cold air inlet by pushing the opening / closing plate.
그러나, 이러한 구성은 냉동실내로 공급되는 냉기의 흐름을 제어할 수는 있을지라도 이는 급속으로 제빙을 할 목적으로 사용되는 것이고, 또한 사용자가 제빙용기를 정확하게 수납하여야만 개폐판이 개폐되므로서 사용상의 불편함이 있는 것이었다.However, although this configuration can control the flow of cold air supplied into the freezer compartment, it is used for the purpose of rapidly deicing, and it is inconvenient for use because the opening and closing plate is opened and closed only when the user correctly stores the ice making container. This was to be.
또, 냉기통로내에도 제상이 발생되므로서 제빙용기를 수납한 상태에서 차폐판이 냉기통로의 측벽에 붙어 떨어지지 않아 오작동이 발생되는 등 작동이 정확하게 이루어지지 않는 문제점도 야기되는 것이었다.In addition, since defrosting occurs in the cold air passage, the shielding plate does not fall on the side wall of the cold air passage in the state in which the ice making container is stored, thereby causing a problem in that the operation is not performed correctly.
본 고안의 상기와 같은 사정을 고려하여 이루어진 것으로, 그 목적은 냉동실내에 설치되는 선반으로서 냉동실로 공급되는 냉기의 흐름을 제어하도록 하므로서 냉기의 대류현상을 촉진시키어 냉동성이 뛰어남과 동시에 사용의 편리성을 향상시킨 것을 제공함에 있다.It is made in consideration of the above circumstances of the present invention, and its purpose is to provide a shelf installed in the freezer compartment to control the flow of cold air supplied to the freezer compartment, thereby promoting the convection of the cold air, resulting in excellent freezing and ease of use. To provide an improvement.
즉, 본 고안은 냉동실의 후벽면 하단부에 증발기로부터 열교환된 냉기가 냉기통로를 거쳐 공급되게 하는 냉기분출구를 구비하고, 이의 냉기분출구에 냉기흐름을 제어하는 제어부를 구비함과 아울러 상기 제어부를 선반부의 보조선반을 전·후 작동시킴에 의해 작동되게 하므로서 공급되는 냉기를 냉동실 선반의 상단 혹은 하단부로 공급 대류토록 한 것을 특징으로 하는 것이다.In other words, the present invention has a cold air outlet for supplying the cold air heat exchanged from the evaporator through the cold passage in the lower end of the rear wall surface of the freezer compartment, the cold air outlet has a control unit for controlling the flow of cold air and the control unit in the shelf part It is characterized in that the convection of the cold air supplied to the upper or lower part of the freezer shelf by operating the auxiliary shelf before and after the operation.
다음 본 고안의 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Next, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도면은 냉장고를 표시한 것으로, 제1도는 전술한 바와같이 일반적인 냉장고의 구성을 개략적으로 보인 측단면도이고, 제2도와 제3도는 본 고안의 구성을 보인 구성도이다.The drawing shows a refrigerator, and FIG. 1 is a side cross-sectional view schematically showing the configuration of a general refrigerator as described above, and FIG. 2 and FIG. 3 are schematic views showing the configuration of the present invention.
본 고안의 주된 목적은 냉기통로를 통하여 냉동실측으로 공급되는 냉기를 냉동실 선반의 상단부측으로는 물론 선반의 하단부로도, 선택적으로 공급되게 하므로서 냉기를 냉동실내에 골고루 공급대류토록 하는 것에 있다.The main object of the present invention is to allow the supply of cold air evenly into the freezer compartment by selectively supplying the cold air supplied to the freezer compartment side through the cold air passage to the lower end of the shelf as well as the upper end side of the freezer compartment.
즉, 냉동실(2)의 후벽면(20)에 구비되어 냉기의 공급방향을 상단 혹은 하단부로 제어하는 제어부(21)와, 냉동실(2)의 중심부에 구비되어 상기 제어부(21)를 작동시키면서도 보관식품을 적재하는 선반부(22)로 구성된다.That is, the control unit 21 is provided on the rear wall surface 20 of the freezing chamber 2 to control the supply direction of the cold air to the upper end or the lower end, and is provided at the center of the freezing compartment 2 to keep the control unit 21 in operation. It consists of the shelf part 22 which loads food.
제어부(21)는 냉동실(2) 후벽면(20)에 구비된 개구(23)에 체결되는 체결판(24)과 이의 체결판(24)에 구비되어 냉기 공급방향을 유도하는 유도판(25)으로 구성된다.The control unit 21 is provided on the fastening plate 24 fastened to the opening 23 provided in the rear wall surface 20 of the freezing chamber 2 and the fastening plate 24 thereof to guide the cold air supply direction 25. It consists of.
상기 체결판(24)은 중심부에 냉기분출구(26)와, 그 후방 양측에 걸림홈(27)을 가지면서 냉동실(2)의 후벽면(20)에 고정되고, 유도판(25)은 하부끝단에 걸림턱(28)과 양측에 회전측(29)이 구비되어 이의 회전축(29)은 체결판(24)의 걸림홈(27)에 끼워 맞춤되어 회동 가능토록 구비되고, 걸림턱(28)은 냉기분출구(26)의 전단하부에 걸려지도록 구비되므로서 유도판(25)이 냉기분출구(26)를 차폐하도록 구성된다.The fastening plate 24 is fixed to the rear wall surface 20 of the freezing chamber 2 with the cold air outlet 26 at the center and the locking groove 27 at both rear sides thereof, and the guide plate 25 is at the lower end. The locking jaw 28 and the rotating side 29 is provided on both sides thereof, the rotary shaft 29 thereof is fitted into the locking groove 27 of the fastening plate 24 so as to be rotatable, and the locking jaw 28 is The guide plate 25 is configured to shield the cold air jet port 26 by being hooked under the front end of the cold air jet port 26.
더욱 상세히 설명하면 유도판(25)은 회전축(29)을 지점으로 상단부보다 하단부의 길이가 더 길기 때문에 자체가 갖는 중량에 의해 외부의 어떤힘이 가해지지 않는 한 항상 냉기분출구(26)를 차폐하고 있는 상태를 유지토록 된 것이다.More specifically, the guide plate 25 has a longer length at the lower end than the upper end with the rotation shaft 29 as a point so that the cold air outlet 26 is always shielded unless some external force is applied by the weight thereof. It is to keep it.
그리고, 선반부(22)는 보관식품을 적재하는 주선반(30)과, 상기 주선반(30)의 하부에서 전·후 슬라이드 작동되면서 제어부(21)의 유도판(25)을 작동시키는 보조선반(31)으로 구성된다.And, the shelf portion 22 is the main shelf 30 for storing the stored food, and the auxiliary shelf for operating the guide plate 25 of the control unit 21 while the slide operation before and after the main shelf (30). It consists of 31.
주선반(30)은 냉동실(2)의 양측벽 슬라이드홈에 체결되고, 다수의 냉기유통공(32)과 양측면에 가이드홈(33)이 구비된다.The main shelf 30 is fastened to both side wall slide grooves of the freezing chamber 2, and is provided with a plurality of cold air distribution holes 32 and guide grooves 33 at both sides thereof.
또, 보조선반(31)은 상기 주선반(30)의 가이드홈(33)에 삽입되어 전·후 작동되고, 표면에 주선반(30)과 동일한 다수의 냉기유통공(32)과 전단에 손잡이(34)와, 그리고 후단에 유도판(25)의 상단부를 밀음작동시키는 작동구(35)가 구비된다.In addition, the auxiliary shelf 31 is inserted into the guide groove 33 of the main shelf 30 to be operated before and after, the handle on the front surface and a number of cold air distribution holes 32 and the same as the main shelf 30 on the surface 34 and an operation tool 35 for pushing and pushing the upper end of the guide plate 25 at the rear end thereof.
또한, 냉기통로(12)내의 냉장고본체에 보조선반(31)이 후진하였을 경우 보조선반(31)의 작동구(35)가 체결되는 체결홈(36)을 구비하여서 된 것이다.In addition, when the auxiliary shelf 31 is reversed to the refrigerator body in the cold air passage 12 is provided with a fastening groove 36 to which the operating port 35 of the auxiliary shelf 31 is fastened.
이와같은 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effect of the present invention in detail as follows.
평상시에는 제3도에서 보는 바와같이 보조선반(31)이 주선반(30)과 일치된 상태, 즉 선반부(22)의 보조선반(31)이 제어부(21)의 유도판(25)에 아무런 영향을 미치지 않는 상태에서는 유도판(25)이 자중에 의해 냉기분출구(26)를 막고 있는 상태를 유지하게 된다.In general, as shown in FIG. 3, the auxiliary shelf 31 coincides with the main shelf 30, that is, the auxiliary shelf 31 of the shelve part 22 is not attached to the guide plate 25 of the controller 21. In the non-affected state, the guide plate 25 keeps the cold air outlet 26 blocked by its own weight.
따라서, 증발기(4)에서 열교환된 냉기는 송풍장치(5)에 의해 냉기통로(12)를 거쳐 상단부의 냉기분출구(13)로 공급되어 냉동실(2)내를 대류하므로서 주선반(30)과 냉동실(2) 저면에 적재된 보관식품을 냉동시키게 되는 것이다.Therefore, the cold air heat-exchanged in the evaporator 4 is supplied to the cold air outlet 13 of the upper end by the blower 5 through the cold air passage 12, convection in the freezer compartment 2 and the freezer compartment 30 and the freezer compartment. (2) Frozen food stored on the bottom.
이같은 냉기흐름은 종래와 동일한 것이며, 다만 주선반(30)에 적재되는 보관식품이 많아 대류되는 냉기가 차단되어 선반부(22)의 하부로 공급되지 않을 경우나 냉동실(2)의 하단부만 집중적으로 냉동시킬 경우에 사용되는 것으로서 보조선반(31)의 손잡이(34)를 잡고 밀면 보조선반(31)은 제5a도와 같은 상태에서 제5b도에서와 같이 전진된다.This cold air flow is the same as in the prior art, but there are many stored foods loaded on the main shelf 30, so that convective cold air is blocked and is not supplied to the lower part of the shelf 22, or only the lower end of the freezer compartment 2 is concentrated. As used in the case of freezing, when the handle 34 of the auxiliary shelf 31 is grasped and pushed, the auxiliary shelf 31 is advanced as shown in FIG.
즉, 보조선반(31)은 주선반(30)의 양측 가이드홈(33)을 따라 슬라이드되면서 작동구(35)가 유도판(25)의 상단을 밀게되고, 이에 따라 유도판(25)은 회전축(29)을 지축으로 시계방향으로 회동되면서 체결판(24)의 냉기 분출구(26)를 개방하게 되는 것이다.That is, the auxiliary shelf 31 slides along the guide grooves 33 on both sides of the main shelf 30 so that the operating tool 35 pushes the upper end of the guide plate 25, whereby the guide plate 25 is rotated. (29) is rotated in the clockwise direction to the axis to open the cold air jet port 26 of the fastening plate (24).
이때, 보조선반(31)의 작동구(35)가 완전히 전진되어 체결홈(36)에 체결되므로서 제5b도에서와 같이 상단부측의 냉기통로(12)를 막음과 동시에 냉기분출구(26)가 개방되어져 냉기는 냉기분출구(26)를 통하여 냉동실(2)로 공급되어지는 것이다.At this time, the operating hole 35 of the auxiliary shelf 31 is fully advanced and fastened to the fastening groove 36 to block the cold air passage 12 at the upper end side as shown in FIG. The cold air is opened and supplied to the freezing chamber 2 through the cold air outlet 26.
한편, 이같이 냉기통로(12)를 개폐하는 유도판(25)은 그 폭을 냉기통로(12)의 폭보다 약간 적게 하므로서 냉동실(2)의 상단부측으로도 냉기가 어느정도 공급되도록 된 것이다.On the other hand, the guide plate 25 that opens and closes the cold air passage 12 in this way is slightly smaller than the width of the cold air passage 12, so that the cold air is supplied to some extent to the upper end side of the freezer compartment (2).
이와는 반대로 냉동실(2)의 주선반(30)에 식품이 적어 상단부의 냉기분출구(13)에서 공굽되는 냉기가 냉동실(2)내에 원활히 대류될 경우에는 보조선반(31)의 손잡이(34)를 잡고 앞으로 당기면 하단부의 냉기분출구(26)가 폐쇄되면서 냉기통로(12)가 개방되어 상단부측으로만 냉기가 공급되는 것이다.On the contrary, in the case where there is little food in the main shelf 30 of the freezer compartment 2 and the cold air that is bent at the cold air outlet 13 of the upper end is smoothly condensed in the freezer compartment 2, the handle 34 of the auxiliary shelf 31 is held. When pulled forward, the cold air ejection opening 26 of the lower end is closed and the cold air passage 12 is opened to supply cold air only to the upper end side.
즉, 제5b도와 같은 상태에서 제5a도에서와 같이 보조선반(31)이 후퇴되므로서 냉기통로(12)를 개방함과 아울러 유도판(25)은 자중에 의해 회전축(29)을 지축으로 반시계 방향으로 회동되어 체결판(24)의 냉기분출구(26)를 폐쇄하게 되는 것이다.That is, in the state as shown in FIG. 5B, as shown in FIG. 5A, as the auxiliary shelf 31 is retracted, the cold air passage 12 is opened, and the guide plate 25 is half the rotary shaft 29 by its own weight. It rotates in a clockwise direction to close the cold air ejection opening 26 of the fastening plate 24.
그러므로, 본 고안은 냉동실내에 구비되는 선반을 이용하여 냉동실로 공급되는 냉기의 공급방향을 제어토록하므로서, 냉동실의 내용적을 침해하지 않고도 설치가 가능한 것이며, 또한, 그 구성이 간단하여 구조성을 향상시킨 효과를 가지게 됨은 물론 보조선반을 밀고 당기기만 하면 냉기흐름이 제어되는 것으로서 사용의 편리성을 향상시키게 되는 효과를 가지게 되는 것이다.Therefore, the present invention allows the installation of the refrigerator to be controlled without infringing the contents of the freezer compartment by controlling the supply direction of the cold air supplied to the freezer compartment by using a shelf provided in the freezer compartment. Of course, the cold air flow is controlled by simply pushing and pulling the auxiliary shelf, which will have the effect of improving the convenience of use.
