본 발명은 콤비 냉장고에 관한 것으로서, 더욱 상세하게는 냉동실에 설치된 증발기의 냉기를 냉동실의 위쪽에 위치한 냉장실로 원활하게 송출하여 냉장실의 냉장효율을 향상시킬 수 있는 크로스 팬이 구비된 콤비 냉장고에 관한 것이다.The present invention relates to a combination refrigerator, and more particularly, to a combination refrigerator having a cross fan that can smoothly send the cold air of the evaporator installed in the freezer compartment to the refrigerating compartment located above the freezer compartment to improve the refrigerating efficiency of the refrigerating compartment. .

냉장고는 냉동실 및 냉장실의 위치에 따라 탑마운트(Top Mount), 콤비(Bottom Freezer), 양문여닫이(Side by Side) 냉장고로 나누어진다.The refrigerator is divided into a top mount, a bottom freezer, and a side by side refrigerator according to the positions of the freezer and the refrigerator compartment.

탑마운트 냉장고는 냉동실이 냉장실의 위쪽에 위치한 형태로서, 냉동실의 무거운 냉기가 자연대류 또는 강제대류에 의해 서서히 냉장실로 이동되어 냉장실을 냉장시키는 구조이므로 제품설계 및 구현이 용이하다. 또한, 탑마운트 냉장고는 폭이 넓어 식품보관이 편리할 뿐만 아니라 냉장실 활용도가 높은 장점이 있다.The top mount refrigerator has a freezer compartment located above the refrigerator compartment, and since the heavy cold air of the freezer compartment is gradually moved to the refrigerator compartment by natural convection or forced convection, it is easy to design and implement a product. In addition, the top-mounted refrigerator has a wide width, it is convenient for food storage and has the advantage of high utilization of the refrigerating compartment.

그러나, 탑마운트 냉장고는 냉장문의 개폐 공간을 많이 차지하고 냉동실과 냉장실의 크기를 확장하는데 한계가 있다. 또한, 탑마운트 냉장고는 일반적으로 음식물이 많이 저장되는 냉장실이 아래쪽에 위치하므로 사용자가 허리를 구부려 음식물을 꺼내야하는 불편함이 있다.However, the top-mounted refrigerator occupies a lot of opening and closing space of the refrigerating door and has a limit in expanding the size of the freezer and the refrigerating compartment. In addition, the top mount refrigerator has a inconvenience that the user has to take out food by bending the waist because the refrigerating chamber in which a lot of food is stored is generally located below.

콤비 냉장고는 냉장실이 냉동실의 위쪽에 위치한 형태로서, 인체공학적으로 사용이 편리하다. 즉, 대부분의 음식물은 냉동실보다 냉장실에 많이 보관되는데, 콤비 냉장고는 냉장실에 저장되는 음식물을 허리를 굽히지 않고 반출 및 반입할 수 있으므로 편리하다.Combi refrigerator is a refrigerator is located above the freezer, ergonomically convenient to use. That is, most of the food is stored in the refrigerator rather than the freezer, the combination refrigerator is convenient because the food stored in the refrigerator can be brought out and brought in without bending.

그러나, 콤비 냉장고는 탑마운트 냉장고와 마찬가지로 크기확장에 제한이 많 으며, 하부 냉동실에 마련된 증발기의 냉기를 송풍기를 이용하여 냉장실로 강제 순환시켜야 하므로 냉장실의 냉장효율이 떨어진다.However, the combination refrigerator is limited in size expansion like the top mount refrigerator, and the refrigeration efficiency of the refrigerating compartment is inferior because the cold air of the evaporator provided in the lower freezing compartment must be forced to circulate into the refrigerating compartment using the blower.

양문여닫이 냉장고는 냉동실과 냉장실이 좌우에 나란히 위치한 형태로서, 문의 개폐가 용이하고 음식물의 수납이 편리하다. 또한, 양문여닫이 냉장고는 냉장고 문의 폭이 탑마운트와 콤비 냉장고에 비해 작으므로 대형화에 유리하다.The double door opening and closing refrigerator is a form in which a freezer compartment and a refrigerating compartment are arranged side by side, and the door is easily opened and closed and food storage is convenient. In addition, the two-door opening and closing refrigerator is advantageous in size because the width of the refrigerator door is smaller than the top mount and combination refrigerator.

그러나, 양문여닫이 냉장고는 냉동실과 냉장실이 상하로 길게 늘어진 형태이므로 냉각효율을 위한 제품설계가 어렵고, 폭이 넓은 식품을 보관하기 불편하다.However, since the two-door refrigerator is a long stretched freezer and refrigerator compartment up and down, it is difficult to design a product for cooling efficiency, it is inconvenient to store a wide range of food.

한편, 최근 들어 원룸 아파트와 같은 1인 주거형태가 늘어나면서 인체공학적 특징을 갖는 콤비 냉장고의 소비가 점차 증대되고 있다. 그러나, 앞서 살펴본 바와 같이 콤비 냉장고는 냉동실에 마련된 증발기의 냉기를 하나의 프로펠러 팬을 통해 위쪽에 위차한 냉장실로 강제 순환시키는 방식이므로 냉장효율이 매우 떨어진다. 따라서, 냉동실의 냉기를 냉장실로 신속하고 원활하게 순환시킬 수 있는 냉기순환구조를 갖는 콤비 냉장고가 요청된다.On the other hand, in recent years, as one-room apartments such as one-room apartments are increasing, the consumption of the combination refrigerator having ergonomic characteristics is gradually increasing. However, as described above, the combination refrigerator forcibly circulates the cold air of the evaporator provided in the freezer compartment through the one propeller fan to the refrigerating compartment located above, and thus the refrigeration efficiency is very low. Therefore, there is a need for a combination refrigerator having a cold air circulation structure capable of quickly and smoothly circulating cold air in a freezer compartment to a cold compartment.

본 발명은 상기와 같은 필요에 의한 것으로서, 냉동실에 설치된 증발기의 냉기가 냉동실의 위쪽에 위치한 냉장실로 원활하게 송출되는 크로스 팬이 구비된 콤비 냉장고를 제공하는데 그 목적이 있다.It is an object of the present invention to provide a combination refrigerator provided with a cross fan, in which cold air of an evaporator installed in a freezer compartment is smoothly discharged to a refrigerating compartment located above the freezer compartment.

본 발명의 한 실시예에 따르면, 냉동실이 냉장실 아래쪽에 위치한 콤비(Bottom Freezer) 냉장고에 있어서, 상기 냉동실에 설치되는 증발기; 상기 증발기의 일 측에 상기 증발기의 너비방향을 따라 길게 설치되는 하나 이상의 크로스 팬; 입구와 출구가 상기 냉동실과 상기 냉장실에 각각 위치되도록 설치되는 팬 덕트; 상기 팬 덕트의 출구와 연결되고, 상기 냉장실의 높이방향을 따라 길게 연장되며, 상기 냉장실과 소통되는 다수의 배출구가 형성되는 냉기 덕트; 및 입구와 출구가 상기 냉장실과 상기 냉장실에 각각 위치되도록 설치되는 귀환 덕트를 포함하는 크로스 팬이 구비된 콤비 냉장고가 제공된다.According to one embodiment of the present invention, a freezer is a Combi (Bottom Freezer) refrigerator located below the refrigerating chamber, the refrigerator comprising: an evaporator installed in the freezer; At least one cross fan installed on one side of the evaporator along a width direction of the evaporator; A fan duct installed such that an inlet and an outlet are respectively located in the freezing compartment and the refrigerating compartment; A cold air duct connected to an outlet of the fan duct, extending along a height direction of the refrigerating compartment, and having a plurality of outlets communicating with the refrigerating compartment; And a return fan including a return duct installed such that an inlet and an outlet are respectively located in the refrigerating compartment and the refrigerating compartment.

바람직하게는, 크로스 팬은 상기 증발기의 상부 측에 설치되는 것이 좋다.Preferably, the cross pan is installed on the upper side of the evaporator.

또한, 냉기 덕트의 상부에는 보조 팬이 더 설치되는 것이 좋다.In addition, it is preferable that an auxiliary fan is further installed at the upper portion of the cold air duct.

또한, 냉장실에는 온도센서가 더 설치되고, 팬 덕트에는 온도센서와 전기적으로 연결되고 온도센서의 측정값에 따라 작동하는 댐퍼가 더 설치되는 것이 좋다.In addition, it is preferable that a temperature sensor is further installed in the refrigerating chamber, and a damper electrically connected to the temperature sensor and operated according to the measured value of the temperature sensor is installed in the fan duct.

또한, 배출구는 대체로 냉장실의 상방을 향하도록 형성되는 것이 좋다.In addition, the discharge port is preferably formed to face upward of the refrigerating chamber.

이하, 본 발명의 바람직한 실시예를 첨부된 예시도면에 의거하여 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 제1실시예에 따른 크로스 팬이 구비된 콤비 냉장고의 주요구성을 나타낸 구성도이고, 도 2는 도 1에 도시된 콤비 냉장고의 냉기 흐름을 나타낸 구성도이다.1 is a block diagram showing the main configuration of the combination refrigerator with a cross fan according to the first embodiment of the present invention, Figure 2 is a block diagram showing the flow of cold air in the combination refrigerator shown in FIG.

도 1에 도시된 바와 같이 콤비 냉장고(100)는 내부가 상하로 분할되고 대체 로 직육면체인 본체(110)를 포함한다. 본체(110)의 상부에는 냉장실(112)이 마련되고, 하부에는 냉동실(114)이 마련된다. As shown in FIG. 1, the combination refrigerator 100 includes a main body 110 that is divided up and down inside and is generally rectangular parallelepiped. A refrigerating chamber 112 is provided at an upper portion of the main body 110, and a freezing chamber 114 is provided at a lower portion thereof.

냉동실(114)의 내부에는 증발기(120), 크로스 팬(130), 모터(135) 등이 설치된다. 증발기(120)는 도시되지 않았으나 압축기 및 팽창밸브와 연결되어 냉각회로를 이루며, 냉장고 가동시 저온상태의 냉매가 순환되어 항상 상온 보다 낮은 온도(대개 영하상태이다)로 유지된다. 따라서 냉동실(114)은 저온의 증발기(120)나 증발기(120)에 의해 냉각된 냉기에 의해 직접 또는 간접적으로 냉각된다.An evaporator 120, a cross fan 130, a motor 135, and the like are installed in the freezer compartment 114. Although not shown, the evaporator 120 is connected to a compressor and an expansion valve to form a cooling circuit. When the refrigerator is operated, a low temperature refrigerant is circulated to maintain a temperature lower than a normal temperature (usually below zero). Therefore, the freezer compartment 114 is directly or indirectly cooled by the cold evaporator 120 or the cold air cooled by the evaporator 120.

크로스 팬(130)은 증발기(120)의 너비 방향과 평행하게 설치되어 증발기(120)의 냉기를 위쪽으로 끌어올린다. 크로스 팬(130)은 원심형 송풍기로서 프로펠러 팬(축류형 팬임)과 달리 팬의 회전반경방향으로 유동을 일으키며, 도 1에 도시된 바와 같이 냉동실의 너비 방향으로 길게 설치되어 강한 냉기의 흐름을 유발한다. 따라서, 크로스 팬(130)을 설치하면 냉동실(114)의 냉기를 위쪽으로 강하게 송출할 수 있다. 크로스 팬(130)의 일 측에는 크로스 팬(130)을 구동시키는 구동수단으로써 모터(135)가 설치된다.The cross fan 130 is installed in parallel with the width direction of the evaporator 120 to raise the cold air of the evaporator 120 upwards. The cross fan 130 is a centrifugal blower which, unlike the propeller fan (which is an axial fan), causes flow in the rotational direction of the fan, and is installed in the width direction of the freezer compartment as shown in FIG. 1 to induce a strong flow of cold air. do. Therefore, when the cross fan 130 is installed, the cold air of the freezing compartment 114 can be strongly transmitted upward. On one side of the cross fan 130, a motor 135 is installed as a driving means for driving the cross fan 130.

냉동실(114)의 위쪽에 마련된 냉장실(112)에는 냉기 덕트(150)가 냉장실(112)의 높이방향을 따라 길게 설치된다. 냉기 덕트(150)는 증발기(120)의 냉기를 냉장실(112) 내부에 고르게 분사하는 구실을 한다. 이를 위해 냉기 덕트(150)에는 다수의 배출구(152)가 일정 간격으로 형성된다. 일반적으로 냉기는 온기보다 무거우므로 아래쪽으로 이동하려는 경향을 갖는다. 따라서, 배출구(152)는 냉기 덕트(150)의 상부에 집중되게 형성되는 것이 좋다.In the refrigerating chamber 112 provided above the freezing chamber 114, a cold air duct 150 is installed along the height direction of the refrigerating chamber 112. The cold air duct 150 serves to spray the cold air of the evaporator 120 evenly into the refrigerating chamber 112. To this end, a plurality of outlets 152 are formed in the cold air duct 150 at regular intervals. Cold air is generally heavier than warmth and therefore tends to move downward. Therefore, the outlet 152 may be formed to be concentrated on the upper portion of the cold air duct 150.

냉장실(112)과 냉동실(114)의 경계면에는 팬 덕트(140)와 귀환 덕트(160)가 냉장실(112)과 냉동실(114)의 경계면을 관통하여 설치된다. 팬 덕트(140)의 입구는 크로스 팬(130)의 반경 방향 부근에 설치되고, 팬 덕트(140)의 출구는 냉기 덕트(150)와 연결된다. 따라서, 크로스 팬(130)에 상부방향으로 끌어 올려진 냉기는 팬 덕트(140)를 통해 냉기 덕트(150)로 송출된다. 귀환 덕트(160)의 입구와 출구는 냉장실(112)과 냉동실(114)의 아래쪽에 각각 위치된다. 귀환 덕트(160)는 냉장실(112)의 하부에 잔류하는 냉기를 냉동실(114)로 순환시키는 구실을 한다.The fan duct 140 and the return duct 160 penetrate the interface between the refrigerating chamber 112 and the freezing chamber 114 at the interface between the refrigerating chamber 112 and the freezing chamber 114. The inlet of the fan duct 140 is installed near the radial direction of the cross fan 130, and the outlet of the fan duct 140 is connected to the cold air duct 150. Therefore, the cold air drawn upward in the cross fan 130 is sent to the cold air duct 150 through the fan duct 140. Inlets and outlets of the return duct 160 are located below the refrigerating chamber 112 and the freezing chamber 114, respectively. The return duct 160 serves to circulate cold air remaining in the lower part of the refrigerating chamber 112 to the freezing chamber 114.

이와 같은 구조를 갖는 본 발명의 냉기 흐름은 도 2에 도시된 바와 같다.Cold air flow of the present invention having such a structure is as shown in FIG.

도 2에 도시된 바와 같이 증발기(120)에 의해 냉각된 냉기는 크로스 팬(130)에 의해 상승하여 팬 덕트(140)를 통해 냉기 덕트(150)로 유입되고, 배출구(152)를 통해 분출되어 냉장실(112)을 냉각한다. 그리고 냉장실(112)을 냉각한 냉기는 귀환 덕트(160)를 통해 냉동실(114)의 바닥 부근에 이동되어 증발기(120)를 통해 다시 냉각된다. 한편, 본 발명에서는 냉기가 증발기(120)의 너비 방향을 따라 길게 설치된 크로스 팬(130)에 의해 증발기(120)의 전역에 걸쳐 활발하게 유동되고 냉장실(112)로 압송되므로, 냉장실(112)이 효과적으로 냉각된다.As shown in FIG. 2, the cold air cooled by the evaporator 120 is lifted by the cross fan 130, introduced into the cold air duct 150 through the fan duct 140, and ejected through the outlet 152. The refrigerator compartment 112 is cooled. The cold air having cooled the refrigerating compartment 112 is moved near the bottom of the freezing compartment 114 through the return duct 160 to be cooled again through the evaporator 120. On the other hand, in the present invention, since the cold air is actively flowed over the whole of the evaporator 120 by the cross fan 130 installed long along the width direction of the evaporator 120 and pumped into the refrigerating chamber 112, the refrigerating chamber 112 is Cooling effectively

다음에서는 냉장실(112)의 냉각효율을 보다 상승시키는 몇 가지 예를 살펴보겠다. 도 3은 본 발명의 제2실시예에 따른 주요 구성도이고, 도 4는 본 발명의 제3실시예에 따른 주요 구성도이다. 제1실시예와 동일한 구성요소는 동일한 도면부호를 부여하며, 이들에 대한 설명은 생략한다.Next, some examples of increasing the cooling efficiency of the refrigerating chamber 112 will be described. 3 is a main configuration diagram according to a second embodiment of the present invention, Figure 4 is a main configuration diagram according to a third embodiment of the present invention. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

제2실시예에 따른 콤비 냉장고(100a)는 보조 팬(170)을 더 구비한다. 보조 팬(170)은 냉기 덕트(150)의 상부에 설치되어, 팬 덕트(140)를 통해 냉장실(112)로 유입된 냉기가 냉기 덕트(150)의 상부 끝까지 끌어올리는 구실을 한다. 냉기 덕트(150)로 유입되는 냉기는 크로스 팬(130)과 보조 팬(170)에 의해 냉장실(112)의 상부까지 상승하여 배출구(152)를 통해 분사된 후 냉장실(112)의 상부에 위치한 비교적 고온의 냉기와 혼합되어 냉장실(112)의 온도를 낮춘다.The combination refrigerator 100a according to the second embodiment further includes an auxiliary fan 170. The auxiliary fan 170 is installed on the upper portion of the cold air duct 150 to serve as an excitation for raising the cold air introduced into the refrigerating chamber 112 through the fan duct 140 to the upper end of the cold air duct 150. The cold air flowing into the cold air duct 150 is raised by the cross fan 130 and the auxiliary fan 170 to the upper part of the refrigerating chamber 112, sprayed through the outlet 152, and is located at the upper part of the refrigerating chamber 112. It is mixed with high temperature cold air to lower the temperature of the refrigerating chamber 112.

본 실시예는 냉동실(114)의 냉기가 보조 팬(170)에 의해 강력하게 분사되므로 냉장실(112)의 냉기순환이 신속하고 효과적으로 이루어지는 장점이 있다. 따라서, 본 실시예는 냉장실(112)이 길고 큰 경우에 효과적이다.In this embodiment, since the cold air of the freezing compartment 114 is strongly injected by the auxiliary fan 170, the cold air circulation of the refrigerating compartment 112 is quickly and effectively performed. Therefore, this embodiment is effective when the refrigerating chamber 112 is long and large.

제3실시예에 따른 콤비 냉장고(100b)는 댐퍼(180)와 온도센서(190)를 더 구비한다. 댐퍼(180)는 팬 덕트(140)에 설치되고, 온도센서(190)는 냉장실(112)에 설치된다. 댐퍼(180)는 온도센서(190)에서 측정된 온도 값을 수신한 제어부(도시되지 않음)의 제어신호에 의해 개폐량이 조절된다. 즉, 냉장실(112)의 온도가 설정온도보다 높으면 댐퍼(180)는 개방되고, 냉장실(112)의 온도가 설정온도보다 낮으면 댐퍼(180)는 폐쇄된다.The combination refrigerator 100b according to the third embodiment further includes a damper 180 and a temperature sensor 190. The damper 180 is installed in the fan duct 140, and the temperature sensor 190 is installed in the refrigerating chamber 112. The damper 180 adjusts the opening and closing amount by a control signal of a controller (not shown) that receives the temperature value measured by the temperature sensor 190. That is, the damper 180 is opened when the temperature of the refrigerating chamber 112 is higher than the set temperature, and the damper 180 is closed when the temperature of the refrigerating chamber 112 is lower than the set temperature.

본 실시예에서는 댐퍼(180)에 의해 냉장실(112)로 소통되는 냉기의 량이 조절되므로, 크로스 팬(130)에 의해 보다 다량의 냉기가 송출될 수 있도록 팬 덕트(140)의 입구를 크게 확장하였다. 아울러, 본 실시예는 냉기 덕트(150)를 유동하는 냉기가 상방으로 분사되어 상대적으로 고온인 냉기와 원활하게 혼합될 수 있도록 배출구(152)를 상방으로 경사지게 형성하였다.In this embodiment, since the amount of cold air communicated to the refrigerating chamber 112 is controlled by the damper 180, the inlet of the fan duct 140 is greatly expanded so that a larger amount of cold air is sent out by the cross fan 130. . In addition, the present embodiment is formed to be inclined upwardly the outlet 152 so that the cold air flowing through the cold air duct 150 is sprayed upward to be smoothly mixed with the relatively high temperature cold air.

이와 같이 이루어진 제3실시예는 온도센서(190)에 의해 냉장실(112)로 공급되는 냉기의 량이 조절되므로, 냉장실 및 냉동실의 온도제어가 용이하다.In the third embodiment, the amount of cold air supplied to the refrigerating chamber 112 is controlled by the temperature sensor 190, and thus the temperature control of the refrigerating chamber and the freezing chamber is easy.

본 발명은 냉동실의 냉기를 냉동실의 상부에 위치한 냉장실로 원활하게 송출할 수 있으며, 이를 통해 냉장실을 효과적으로 냉각시킬 수 있다. 따라서, 본 발명에 따르면 콤비 냉장고의 단점인 냉장실의 온도상승 문제를 확실히 해결할 수 있다.The present invention can smoothly send the cold air of the freezer compartment to the refrigerating compartment located on the upper portion of the freezer compartment, thereby effectively cooling the refrigerating compartment. Therefore, according to the present invention, it is possible to reliably solve the problem of temperature rise in the refrigerating compartment, which is a disadvantage of the combination refrigerator.
