Description
본 발명은 사이드 바이 사이드형(side-by-side type) 냉장고의 냉기순환장치에 관한 것으로, 보다 상세하게는 냉동실 상면에 증발기를 구비하고 증발기에서 생성된 냉기를 횡류팬으로 냉장실로 공급한 후 일부 냉기는 덕트를 통해 냉장실 배면에서 냉장실 전면으로 토출토록 함과 동시에 다른 일부 냉기는 냉장실 상면에서 직하방으로 직접 토출되도록 한 사이드 바이 사이드형 냉장고의 냉기순환장치에 관한 것이다.The present invention relates to a cold air circulation device of a side-by-side type refrigerator, and more particularly, having an evaporator on an upper surface of a freezer compartment and supplying the cold air generated in the evaporator to a refrigerating compartment by a cross flow fan. It relates to a cold air circulation system of a side-by-side type refrigerator in which cold air is discharged from the rear side of the refrigerating compartment through a duct to the front side of the refrigerating compartment, and at the same time, some other cold air is discharged directly from the upper side of the refrigerating compartment.
일반적으로, 사이드 바이 사이드형 냉장고는 비교적 큰 용량을 가지고 여러 가지 기능이 복합적으로 구비된 것으로, 냉동실과 냉장실이 각각 종방향으로 수직되게 냉장고의 좌우양측에 마련되고 냉동실의 배면에는 증발기가 설치되는 냉각기실이 구비되어 냉동실과 냉장실의 고내 공기를 하부측으로 흡입함과 동시에 상부측으로 토출되게 하여 각 고내로 순환시킴으로써 냉장기능과 냉동기능을 각각 수행하도록 이루어진 것이다.In general, the side-by-side refrigerator has a relatively large capacity and is equipped with a plurality of functions, the refrigerator is provided on the left and right sides of the refrigerator so that the freezer compartment and the refrigerating compartment, respectively, in the vertical direction, and the evaporator is installed on the rear side of the freezer compartment. The chamber is provided to suck the air in the freezer compartment and the refrigerating compartment to the lower side and discharge it to the upper side, thereby circulating into each compartment to perform the refrigerating and freezing functions, respectively.
이러한 사이드 바이 사이드형 냉장고는 대한민국 실용신안공보 제93-44호에 제안된 바와 같이, 해당 고내에 각각 식품을 올려 보관하기 위한 선반이 상,하 선택적으로 이동가능하게 구성되고, 이들 중 상부측 선반의 하부에는 별도의 식품용기를 서랍식으로 수납하여 보관할 수 있도록 된 식품용기 수납장치가 구비된 것도 있다.Such a side-by-side refrigerator is a shelf for placing foods in the refrigerator, respectively, as proposed in Korean Utility Model Publication No. 93-44, which can be selectively moved up and down, among which the upper shelf The lower portion of the food container is also provided with a storage device for storing a separate food container in a drawer type.
이와 같은 사이드 바이 사이드형 냉장고는 도 1에 도시된 바와 같이, 각각 수직으로 평행하게 형성되고 사절부(60)에 의해 분리구획되도록 마련되는 냉동실(F) 및 냉장실(R)과, 상기 냉동실(F)의 후방에 상기 냉동실과 별개의 공간을 형성하도록 분리구획되어 형성되고 증발기(20) 및 송풍팬(30)이 설치되는 냉각기실(10)과, 상기 냉각기실(10)에서 생성된 냉기를 냉장실(R)로 공급하도록 상기 사절부(60)의 상부측에 형성되는 공급덕트(40)와, 상기 냉장실(R)에서 온도상승된 냉기가 상기 냉각기실(10)로 귀환되는 통로로서 상기 사절부(60)의 하부측에 형성된 흡입덕트(50)와, 상기 공급덕트(40)의 냉장실측에 설치되고 공급되는 냉기량을 조절하도록 된 댐퍼(80)로 구성된다.As shown in FIG. 1, the side-by-side refrigerators are freezer compartment F and a refrigerator compartment R, which are formed in parallel to each other and are separated by a trimming unit 60, and the freezer compartment F. The cooler chamber 10 is formed to be separated into the rear of the freezer compartment to form a separate space and the evaporator 20 and the blower fan 30 are installed, and the cold air generated in the cooler chamber 10 is a refrigerating chamber. The feed duct 40 formed on the upper side of the trimming section 60 so as to be supplied to (R), and the passage as a passage through which the cold air whose temperature rises in the refrigerating chamber R is returned to the cooler chamber 10. The suction duct 50 formed in the lower side of the 60, and the damper 80 is provided to adjust the amount of cold air installed and supplied to the refrigerating chamber side of the supply duct 40.
따라서, 증발기(20)에서 생성된 냉기는 송풍팬(30)에 의해 냉동실(F) 및 냉장실(R)로 강제 공급되고, 각 고내에 수납중인 저장물품과 열교환되면서 온도상승된 냉기는 다시 증발기(20) 측으로 귀환되는 순환을 반복하면서 냉장고를 냉각시키게 된다.Therefore, the cold air generated in the evaporator 20 is forcibly supplied to the freezing chamber F and the refrigerating chamber R by the blower fan 30, and the cold air that has risen in temperature while being heat-exchanged with the storage items stored in each chamber is again evaporated ( 20) The refrigerator is cooled while repeating the circulation returned to the side.
이때에, 특히 냉장실의 경우는 고내 전체가 균일한 냉각온도를 유지함이 바람직하므로 냉기분배를 원활하게 가이드하기 위하여 고내 배면측에 멀티덕트(70)가 구비된다.At this time, especially in the refrigerating chamber, it is preferable that the entire interior of the refrigerator maintains a uniform cooling temperature, so that the multi duct 70 is provided on the rear surface of the interior to smoothly distribute the cold air distribution.
그런데, 이와 같은 종래의 사이드 바이 사이드형 냉장고는 냉동실(F) 후방에 별도의 냉각기실(10)을 마련하여야 하므로 냉동실의 활용공간이 매우 좁고 구조도 복잡하다는 문제점이 있었다.However, such a conventional side-by-side refrigerator has a problem that the utilization space of the freezer compartment is very narrow and the structure is complicated because the separate cooler chamber 10 must be provided behind the freezer compartment (F).
또한, 하나의 축류팬(팬의 회전방향과 직교되는 방향으로 공기를 송풍시키도록 된 팬)을 통해 냉각기실의 냉기가 냉장실(R)로 강제 유도되기 때문에 냉장실(R) 전면과 냉장실(R) 상측 배면에는 냉기토출량이 적어 냉기가 토출되는 주변부에 비해 냉각되는 시간이 상대적으로 오래걸린다는 단점도 있었다.In addition, since the cool air in the cooler chamber is forcibly introduced into the refrigerating chamber (R) through one axial flow fan (a fan which blows air in a direction orthogonal to the rotation direction of the fan), the front of the refrigerating chamber (R) and the refrigerating chamber (R). There was also a disadvantage that the cooling time is relatively long compared to the peripheral portion of the cold air discharge due to the small amount of cold air discharge on the upper side.
본 발명은 이와같은 종래기술의 제반 문제점을 감안하여 이를 해결하기 위하여 창출한 것으로, 증발기를 냉동실 천정면에 매립하는 방식으로 냉동실 공간을 극대화시킴과 동시에 냉장실 상측에는 강제유도된 냉기가 냉장실 전면 상측에서 그 직하방으로 직접 토출공급될 수 있도록 하여 에어커튼 효과도 누릴 수 있도록 한 사이드 바이 사이드형 냉장고의 냉기순환장치를 제공코자 함에 그 목적이 있다.The present invention was created in view of the above-mentioned problems of the prior art to maximize the freezer compartment space by embedding the evaporator on the ceiling of the freezer compartment and at the same time the cold air induced in the refrigerating compartment above the refrigerating compartment in the upper side of the refrigerator compartment It is an object of the present invention to provide a cold air circulation system of a side-by-side type refrigerator that can directly discharge and supply directly under the air curtain effect.
본 발명의 또 다른 목적은, 횡류팬(팬의 회전방향과 동일한 방향으로 공기가 송풍되도록 하는 팬)을 사절부에 설치하여 냉장실로 공급되는 냉기의 송풍량을 증대시키도록 한 사이드 바이 사이드 냉장고의 냉기순환장치를 제공코자 함에 있다.Still another object of the present invention is to provide a cross-flow fan (a fan that blows air in the same direction as the rotational direction of the fan) in the trimming section to increase the air flow rate of the cold air supplied to the refrigerating chamber to increase the cold air of the side-by-side refrigerator. To provide a circulation device.
본 발명의 이러한 목적은 사절부에 의해 냉동실 및 냉장실이 각각 수직으로 형성되고 이들이 좌우양측으로 병설되어 이루어지는 사이드 바이 사이드형 냉장고의 냉기순환장치에 있어서, 상기 냉동실의 천정면에 설치고정되는 증발기와, 상기 증발기와 대응되는 위치의 상기 사절부 상측부에 상기 증발기가 설치된 냉각기실과 냉장실이 서로 연통되도록 사절부를 관통하여 형성된 긴 슬롯형의 관통공과, 상기 관통공에 설치되어 콤프레서와 연동되게 제어되도록 냉장고의 제어부에 전기적으로 연결된 크로스플로우팬과, 상기 크로스플로우팬과 인접한 냉장실 상측공간을 분리 구획하여 상기 냉각기실과 연통되는 안내덕트를 형성하는 분할판과, 상기 분할판에 의해 형성된 안내덕트의 후측과 연통되며 상기 냉장실 배면을 따라 직하방으로 길게 설치되며 그 전면에 다수의 냉기토출구를 갖는 냉기분배덕트와, 상기 냉장실의 온기가 상기 냉각기실로 귀환될 수 있도록 상기 사절부의 냉장실측단면에 형성된 리턴덕트로 구성함에 의하여 달성된다.The object of the present invention is a cold air circulation system of a side-by-side refrigerator, in which a freezer compartment and a refrigerating compartment are formed vertically by a trimmer and are arranged side by side, respectively, comprising: an evaporator fixed to the ceiling surface of the freezer compartment, A long slot-type through hole formed through the trimmer to communicate with the cooler chamber and the refrigerating chamber in which the evaporator is installed at an upper portion of the trimmer at a position corresponding to the evaporator, and installed in the through hole to be controlled to be linked with the compressor.

이하에서는, 이러한 본 발명에 따른 구체적인 일 실시예를 첨부도면에 의거하여 예시적인 방법으로 상세히 설명한다.Hereinafter, a specific embodiment according to the present invention will be described in detail by way of example based on the accompanying drawings.
도 2 는 본 발명에 따른 사이드 바이 사이드형 냉장고의 냉기순환장치를 도시한 평단면도이다.2 is a plan sectional view showing a cold air circulation system of a side-by-side refrigerator according to the present invention.
도시된 바와 같이, 냉장고의 좌우양측에 각각 소정크기의 공간이 수직하게 형성된 후 측방향으로 병설되되 사절부(100)에 의해 분리구획되어 냉동실(F) 및 냉장실(R)을 구성한다.As shown, spaces of a predetermined size are formed vertically on the left and right sides of the refrigerator, respectively, and are arranged in the lateral direction but separated and partitioned by the trimmer 100 to configure the freezer compartment F and the refrigerating compartment R. As shown in FIG.
상기 냉동실(F)의 상면, 즉 천정면에는 그 크기와 대응되게 형성된 증발기(210)가 설치된다.An evaporator 210 is formed on an upper surface of the freezing chamber F, that is, a ceiling surface, to correspond to its size.
따라서, 상기 증발기(210)는 냉동실(F)의 천정면에 수납된 형상으로 고정되며, 생성된 냉기는 냉동실(F) 하측방향을 향하여 흘러내리는 형상이 된다.Therefore, the evaporator 210 is fixed to the shape accommodated in the ceiling surface of the freezer compartment F, and the generated cold air flows down toward the lower side of the freezer compartment F.
한편, 상기 사절부(100)는 그 상단측에 사절부(100)의 길이방향을 따라 다소 긴 슬롯형태의 장공으로 된 관통공(130)이 형성된다.On the other hand, the trimming part 100 is formed in the upper end side of the through hole 130 is made of a rather long slot-shaped long hole along the longitudinal direction of the trimming part 100.
상기 관통공(130)은 증발기(210)가 설치된 상기 냉동실(F)의 상측과 냉장실(R)의 상측이 연통되도록 관통형성된다.The through hole 130 is formed so that the upper side of the freezing chamber (F) and the upper side of the refrigerating chamber (R) in which the evaporator 210 is installed communicate with each other.
그리고, 상기 관통공(130)에는 횡류팬인 크로스플로우팬(110)이 설치된다.In addition, the through-hole 130 is provided with a crossflow fan 110 that is a cross flow fan.
상기 크로스플로우팬(110)은 그 회전방향으로 냉기를 안내하여 토출시키도록 된 팬이다.The crossflow fan 110 is a fan configured to guide and discharge cold air in a rotational direction thereof.
또한, 상기 크로스플로우팬(110)의 일단에는 구동모터(120)가 구비된다.In addition, one end of the crossflow fan 110 is provided with a drive motor 120.
상기 구동모터(120)는 냉장고의 마이크로프로세서(이하 "제어부"라 함)에 연결된다.The drive motor 120 is connected to a microprocessor of the refrigerator (hereinafter referred to as a "control unit").
즉, 기계실에 설치된 콤프레서의 구동과 동시에 동작되도록 상기 제어부에 의해 구동제어된다.That is, the drive is controlled by the control unit so as to operate simultaneously with the drive of the compressor installed in the machine room.
냉장실(R)의 상측에는 상기 크로스플루우팬(110)이 설치된 사절부(100)의 관통공(130)과 연통되는 공간을 형성하도록 분할판(300)이 고정된다.The partition plate 300 is fixed to an upper side of the refrigerating chamber R so as to form a space in communication with the through-hole 130 of the trimming part 100 provided with the cross flow fan 110.
상기 분할판(300)의 선단부에는 그 횡방향을 따라 다수의 냉기토출구(310)가 형성된다.A plurality of cold air discharge ports 310 are formed in the front end portion of the partition plate 300 along the transverse direction thereof.
따라서, 냉장실(R)로 강제유도된 냉기는 상기 분할판(300)에 의해 구획된 냉장실(R) 상측 공간인 후술할 안내덕트(330)의 선단측 냉기토출구(310)를 통해 냉장실(R) 전면 직하방으로 토출공급되게 된다.Therefore, the cold air forced into the refrigerating chamber R is stored in the refrigerating chamber R through the cold air outlet 310 of the front side of the guide duct 330 to be described later, which is an upper space of the refrigerating chamber R partitioned by the partition plate 300. The discharge is supplied directly below the front surface.
그리고, 상기 분할판(300)의 후측단은 상기 크로스플로우팬(110)에 인접된 측은 다소 넓은 폭을 갖고 그 대향측은 상대적으로 좁은 폭을 갖도록 완만하게 만곡진 냉기분배덕트(130)가 형성된다.In addition, the rear end of the splitter 300 has a gently curved cold air distribution duct 130 is formed so that the side adjacent to the crossflow fan 110 has a rather wide width and the opposite side has a relatively narrow width. .
상기 냉기분배덕트(130)는 냉장실(R) 배면을 따라 그 하단측까지 연장되어 설치된다.The cold air distribution duct 130 is installed to extend to the lower end side along the rear surface of the refrigerating chamber (R).
도 3은 본 발명에 따른 사이드 바이 사이드형 냉장고의 냉기순환장치의 요부 사시도이다.Figure 3 is a perspective view of the main portion of the cold air circulation of the side-by-side refrigerator according to the present invention.
도시된 바와 같이, 냉동실(F)의 상측공간은 격벽(202)에 의해 상기 냉동실(R)이 상하방향으로 구획되어 냉각기실(200)이 형성된다.As shown in the drawing, the upper space of the freezing compartment F is partitioned in the up and down direction by the partition 202 so that the cooler chamber 200 is formed.
상기 냉각기실(200)은 그 전면이 폐쇄된 상태를 유지토록 형성되며, 증발기(210)가 설치되었을 때에도 상기 냉각기실(200)의 하측 공간이 다소 여유롭게 되도록 한다.The cooler chamber 200 is formed to maintain the front of the closed state, so that even when the evaporator 210 is installed, the lower space of the cooler chamber 200 is somewhat relaxed.
부연하면, 본 발명의 첨부된 도면에는 도시하지 않았으나 상기 냉동실(F)측으로 냉기를 공급하기 위하여 상기 냉각기실(200)의 배면측에는 냉동실(F) 직하방으로 연통되는 송풍팬을 설치할 수도 있으며, 혹은 냉동실(F)의 측벽을 통해 상기 냉동실(F) 전체로 냉기를 공급할 수 있는 구조를 갖출 수도 있다.In other words, although not shown in the accompanying drawings of the present invention in order to supply cold air to the freezing chamber (F) side may be provided with a blower fan communicating directly below the freezing chamber (F), or A structure capable of supplying cold air to the entire freezer compartment F through the sidewall of the freezer compartment F may be provided.
한편, 냉장실(R)에 설치된 냉기분배덕트(320)는 각 선반(360)과 겹치지 않는 위치에 다수의 냉기토출구(322)가 형성된다.On the other hand, the cold air distribution duct 320 installed in the refrigerating chamber (R) is formed with a plurality of cold air outlet 322 in a position that does not overlap with each shelf (360).
그리고, 사절부(100)의 냉장실측면 내측에는 상기 냉각기실(100)과 연통되는 리턴덕트(400)가 형성된다.In addition, a return duct 400 communicating with the cooler chamber 100 is formed inside the refrigerating chamber side of the trimmer 100.
이러한 구성으로 이루어진 본 발명의 사이드 바이 사이드형 냉장고의 냉기순환장치는, 평상모드로 정상운전되다가 고내를 냉각시킬 시점에 도달하여 냉각모드로 전환되게 되면 콤프레서의 구동과 동시에 사절부(100)의 상측에 설치된 크로스플로우팬(110)이 구동되게 된다.The cold air circulation system of the side-by-side type refrigerator of the present invention having such a configuration is operated in the normal mode, and when the internal temperature of the refrigerator is reached and the air conditioner is switched to the cooling mode, the compressor is driven and the upper side of the trimmer 100 simultaneously. The crossflow fan 110 is installed to be driven.
따라서, 냉각기실(200)의 증발기(210)에서 생성된 냉기의 일부는 상기 크로스플로우팬(110)에 의해 냉장실(R)의 안내덕트(330)로 압송된다.Therefore, a part of the cold air generated in the evaporator 210 of the cooler chamber 200 is pumped by the crossflow fan 110 to the guide duct 330 of the refrigerating chamber R.
이후, 상기 안내덕트(330)로 압송된 일부 냉기는 그 송풍압에 의해 분할판(300)에 형성된 냉기토출구(310)를 통해 냉장실(R) 전면 상측에서 그 직하방으로 강하게 토출되어 일종의 에어커튼형상을 이루게 된다.Thereafter, some of the cold air conveyed to the guide duct 330 is strongly discharged from the upper side of the front side of the refrigerating chamber R through the cold air discharge port 310 formed in the partition plate 300 by the blowing pressure, and is a kind of air curtain. Shape.
또한, 상기 안내덕트(330)로 압송된 나머지 일부 냉기는 상기 안내덕트(330)의 후측에 형성된 냉기분배덕트(320)를 통해 냉장실(R) 배면측을 타고 냉장실(R) 하측으로 이동되면서 선반(360)에 의해 칸칸이 구획된 냉장실의 각 부분을 향해 토출되게 되는 바, 즉 상기 냉기분배덕트(320)의 냉기토출구(322)를 통해 그 전방으로 강하게 토출되게 된다.In addition, the remaining part of the cold air conveyed to the guide duct 330 is moved to the lower side of the refrigerating chamber (R) through the cold compartment (R) rear side through the cold air distribution duct 320 formed on the rear side of the guide duct (330). The compartments are discharged toward the respective compartments of the refrigerating compartment in which the compartments are partitioned by 360, that is, strongly discharged forward through the cold air discharge ports 322 of the cold air distribution duct 320.
이렇게 하여 냉장실로 공급된 냉기는 고내를 순환하면서 수납중인 식품들을 냉각시키게 된다.In this way, the cold air supplied to the refrigerating compartment circulates the inside of the refrigerator to cool the foods stored therein.
또한, 이러한 열교환 과정을 통하여 고내는 냉각되고 냉기는 온도상승되어 온기로 바뀌게 된다.In addition, through the heat exchange process, the inside of the chamber is cooled and the cold air is heated to change to warmth.
그리고, 사절부(100)의 상측에서 냉기를 냉장실(R)로 강제 송풍시키는 크로스플로우팬(110)의 송풍압에 의해 냉각기실(200)은 순간적으로 음압(陰壓)이 걸리게 되고 이와 연통된 리턴덕트(400)를 통해 온도상승된 냉기가 상기 냉각기실(200) 측으로 흡입되게 되어 냉장실로의 냉기공급과 귀환을 이루는 순환작용이 반복되게 된다.In addition, by the blowing pressure of the crossflow fan 110 forcibly blowing cold air into the refrigerating chamber R from the upper part of the trimming part 100, the cooler chamber 200 is momentarily subjected to a negative pressure and communicated with this. The cold air that has risen in temperature through the return duct 400 is sucked into the cooler chamber 200 so that the circulation operation of supplying and returning the cold air to the refrigerating chamber is repeated.
이상에서 설명한 바와 같이 본 발명은, 냉동실과 냉장실이 수직하게 형성되고 좌우측으로 병설됨으로서 형성된 사이드 바이 사이드형 냉장고의 사절부 상측에 횡류팬인 크로스플로우팬을 설치함과 동시에 냉동실 상측부에 일정크기의 냉각기실을 구비하고 그 천정면에는 증발기를 설치토록 함으로써, 냉동실의 활용공간을 극대화시키는 효과를 제공하게 된다.As described above, the present invention provides a crossflow fan, which is a cross-flow fan, on the upper side of the trimmer of the side-by-side type refrigerator formed by vertically forming the freezer compartment and the refrigerating compartment, and arranged side by side. By providing a cooler chamber and installing an evaporator on the ceiling surface, it provides an effect of maximizing the utilization space of the freezer compartment.
뿐만 아니라, 크로스플로우팬으로부터 강제유도된 냉기를 골고루 분산시키기 위해 냉장실 상측을 분할판을 구획하여 안내덕트를 형성하고 이 안내덕트 후측에는 냉장실 배면을 따라 배설되는 냉기분배덕트를 구비하여 공급된 냉기가 냉장실 전면 상측에서 그 직하방으로 토출됨과 동시에 그 배면에서 전방으로 토출되도록 함으로써 효율적인 입체냉각을 실현시키는 효과도 제공하게 된다.In addition, in order to evenly distribute the cold air forced from the crossflow fan, the upper part of the refrigerating compartment is partitioned to form a guide duct. The rear side of the guide duct is provided with a cold air distribution duct disposed along the rear side of the refrigerating chamber. By discharging to the front of the refrigerating chamber front side directly below and discharging to the front from the rear side thereof, the effect of realizing efficient three-dimensional cooling is also provided.
