본 발명은 냉장고의 급속냉동장치에 관한 것으로서, 더욱 상세하게는 냉동실과 별도의 급속냉동실을 형성하고, 냉동실의 냉기를 이용하여 상기 급속냉동실 내부를 단시간에 냉각시킬 수 있는 냉장고의 급속냉동장치에 관한 것이다.The present invention relates to a rapid freezing apparatus for a refrigerator, and more particularly, to a rapid freezing apparatus for a refrigerator capable of forming a rapid freezing chamber separate from a freezing chamber and cooling the interior of the rapid freezing chamber in a short time by using cool air in the freezing chamber will be.

일반적으로 냉장고는 사절부에 의해 냉장고의 상부와 하부가 분리 구획되어 상부에는 냉동실이 형성되고, 하부에는 냉장실이 형성되며 이러한 냉동실과 냉장실의 전방으로는 냉동실 도어 및 냉장실 도어가 각각 개폐 가능하게 설치되어 냉기의 누출을 막고 냉장고 내의 기밀을 유지할 수 있도록 되어 있다.Generally, the refrigerator is divided into upper and lower parts of a refrigerator by a trunnion part so that a freezing compartment is formed at the upper part and a refrigerating compartment is formed at the lower part, and the freezing compartment door and the refrigerating compartment door are opened and closed respectively in front of the freezing compartment and the refrigerating compartment Thereby preventing leakage of cold air and maintaining airtightness in the refrigerator.

구체적으로, 냉동실의 후방 내측에는 증발기가 장착되어 냉매 싸이클에 의해 냉기를 생성하고, 이 냉기는 냉동실팬의 구동에 의해 냉동실 내부를 순환하여 냉동실을 냉각하게 되며, 냉장실팬의 구동에 의해 냉동실과 냉장실을 연통하는 냉기덕트를 통하여 냉장실로 유입되어 냉장실의 온도를 유지하게 된다.Specifically, an evaporator is mounted inside the freezing chamber to generate cool air by a coolant cycle. The cool air is circulated in the freezing chamber by the operation of the freezing chamber fan to cool the freezing chamber. By driving the freezing chamber fan, So that the temperature of the refrigerating compartment is maintained.

한편, 냉동실에는 장기 보존을 위해 냉동 보관되어야 하는 식품을 저장하게 되는데, 이러한 식품 중 육류나 생선 등은 고유의 맛을 유지하기 위하여 급속냉각을 하여 보관해야 하지만, 냉동실에 보관된 다른 종류의 식품까지 온도영향이 미치게 된다는 문제점이 있다. On the other hand, in the freezer room, foods that should be kept frozen for long-term preservation are stored. In order to maintain the inherent taste, meat and fish must be rapidly cooled and stored. However, There is a problem that the temperature is affected.

또한, 상온의 음료를 단시간에 냉각하여 마시고 싶은 경우에도, 상술한 바와 같이, 냉동실의 하강된 온도에 의해 냉동실에 보관되어 있는 다름 식품에 영향을 미치게 된다는 문제점이 있다.In addition, even if a beverage of a normal temperature is to be cooled down for a short period of time, there is a problem in that the lowered temperature of the freezing chamber affects different foods stored in the freezing chamber as described above.

상기한 문제점을 해결하기 위하여 본 발명은 냉동실과 별도의 급속냉동실을 형성하고, 냉동실의 냉기를 이용하여 상기 급속냉동실 내부를 단시간에 냉각시킬 수 있는 냉장고의 급속냉동장치를 제공하는 것을 목적으로 한다.It is an object of the present invention to provide a rapid freezing device for a refrigerator which can form a rapid freezing room separate from a freezing room and cool the inside of the rapid freezing room in a short time by using cold air of the freezing room.

상기한 목적을 달성하기 위하여 본 발명에 따른 냉장고의 급속냉동장치는 냉매의 순환에 의한 열교환에 의해 냉기를 생성하는 증발기; 냉장고 본체 내부에 형성되어 상기 증발기로부터 발생하는 냉기에 의해 내부공간을 냉각하는 냉동실; 상기 냉장고 본체 내부에 형성되어 상기 냉동실과 소통되고, 상기 증발기로부터 발생하는 냉기에 의해 내부공간을 냉각하는 급속냉동실; 상기 냉동실과 급속냉동실의 냉기가 서로 소통되도록 상기 냉동실과 급속냉동실을 연결하는 냉기 덕트; 상기 냉동실 내부의 냉기덕트 출입구측에 설치되어 냉기가 유동되도록 하는 DC팬; 상기 급속냉동실 내부의 냉기덕트 입구에 설치되어 냉기가 역류하는 것을 방지하는 역류방지수단; 사용자의 선택사항을 입력하는 입력부의 신호에 의해 상기 DC팬이 구동되도록 제어신호를 출력하는 제어부를 포함하는 것을 특징으로 한다.According to an aspect of the present invention, there is provided a rapid freezing device for a refrigerator, comprising: an evaporator for generating cold air by heat exchange by circulation of a refrigerant; A freezing chamber formed in the main body of the refrigerator to cool the inner space by cool air generated from the evaporator; A rapid freezing chamber formed in the main body of the refrigerator and communicating with the freezing chamber to cool the inner space by cool air generated from the evaporator; A cool air duct connecting the freezing chamber and the quick freezing chamber so that the cold air in the freezing chamber and the rapid freezing chamber communicate with each other; A DC fan installed on the cold air duct entrance side of the freezer compartment to allow cool air to flow; Backflow preventing means installed at the inlet of the cool air duct in the rapid freezing chamber to prevent the cool air from flowing backward; And a control unit for outputting a control signal for driving the DC fan according to a signal of an input unit for inputting a user's selection.

또한, 상기 냉동실 내부의 온도를 감지하는 냉동실 온도 감지 센서 및 상기 급속냉동실 내부의 온도를 감지하는 급속냉동실 온도 감지 센서를 더 포함하고, 상 기 제어부는 상기 냉동실 온도 감지 센서 및 급속냉동실 온도 감지 센서를 통해 감지된 온도에 따라 상기 DC팬의 회전방향을 제어하여 상기 냉동실 및 급속냉동실의 온도를 제어하는 것을 특징으로 한다.The controller may further include a freezer compartment temperature sensor for sensing a temperature inside the freezer compartment, and a rapid freezer compartment temperature sensor for sensing a temperature inside the freezer compartment, wherein the controller includes the freezer compartment temperature sensor and the rapid freezer compartment temperature sensor And the temperature of the freezing chamber and the rapid freezing chamber is controlled by controlling the rotation direction of the DC fan according to the sensed temperature.

또한, 상기 제어부는 상기 냉동실 및 급속냉동실의 온도가 일정하게 유지되도록 하는 일반 냉동모드시, 냉동실 온도 감지 센서를 통해 감지된 온도가 급속냉동실 온도 감지 센서를 통해 감지된 온도보다 1℃ 이상 높은 경우, 상기 냉동실 측으로 냉기가 유입되도록 상기 DC팬을 구동하고, 냉동실 온도 감지 센서를 통해 감지된 온도가 급속냉동실 온도 감지 센서를 통해 감지된 온도보다 1℃ 이상 낮은 경우, 상기 급속냉동실 측으로 냉기가 유입되도록 상기 DC팬을 구동하는 것을 특징으로 한다.When the temperature sensed by the freezer compartment temperature sensor is higher than the sensed temperature through the rapid freezer compartment temperature sensor in the normal freezing mode in which the temperatures of the freezer compartment and the rapid freezer compartment are kept constant, The DC fan is driven so that cool air flows into the freezer compartment, and when the temperature sensed through the freezer compartment temperature sensor is lower than 1C by a temperature sensed by the rapid freezer compartment temperature sensor, And the DC fan is driven.

또한, 상기 제어부는 상기 급속냉동실의 온도가 급격하게 하강되도록 하는 급속냉동모드시, 상기 냉동실의 냉기가 급속냉동실로 유입되도록 DC팬을 구동하고, 이후 상기 냉동실 온도 감지 센서를 통해 감지된 온도가 기 설정온도 이상이 되면 상기 DC팬의 회전방향이 반대가 되도록 상기 DC팬을 구동하는 것을 특징으로 한다.In the rapid freezing mode in which the temperature of the rapid freezing chamber is rapidly lowered, the controller drives the DC fan so that the cold air in the freezing chamber flows into the rapid freezing chamber, And drives the DC fan so that the rotation direction of the DC fan is opposite to the set temperature.

또한, 상기 증발기는 상기 냉동실 및 급속냉동실의 외측 내상에 파이프형태로 삽입 장착한 것을 특징으로 한다.Further, the evaporator is inserted and mounted on the inside of the outside of the freezing chamber and the quick freezing chamber in the form of a pipe.

또한, 상기 역류방지수단은 상기 냉기덕트 입구에 일측이 회동가능하게 장착되어 냉기의 유동방향에 따라 개폐되는 플랩인 것을 특징으로 한다.The backflow prevention means is a flap whose one side is rotatably mounted to the inlet of the cool air duct and is opened or closed according to the flow direction of the cool air.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세하게 설명 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG.

도면에 도시된 바와 같이, 냉장고 본체(100) 내부에는 냉매싸이클에 의해 생성되는 냉기를 이용하여 내부공간을 냉각하는 냉동실(110)과, 냉동실(110)의 하부측에 냉동실(110)과 소통이 되며 냉매싸이클에 의해 발생하는 냉기를 이용하여 내부공간을 냉각하는 급속냉동실(120)이 형성된다.As shown in the drawing, a refrigerator body 100 includes a freezer compartment 110 for cooling an internal space using cool air generated by a refrigerant cycle, and a freezer compartment 110 communicating with the freezer compartment 110 on the lower side of the freezer compartment 110. [ And a rapid freezing chamber 120 for cooling the inner space by using cool air generated by the coolant cycle is formed.

냉동실(110) 및 급속냉동실(120) 내부가 냉각되도록 냉매의 순환을 통해 냉기를 생성하는 증발기(130)는 냉동실(110) 및 급속냉동실(120)의 후방측에 위치되어도 무방하나, 냉동실(110) 및 급속냉동실(120)을 보다 원활하게 냉각할 수 있도록 냉동실(110) 및 급속냉동실(120)의 외측 내상에 파이프 형태로 냉동실(110) 및 급속냉동실(120)을 감싸듯이 삽입 장착된다. The evaporator 130 that generates cool air through the circulation of the refrigerant so that the inside of the freezer compartment 110 and the rapid freezer compartment 120 is cooled may be located at the rear side of the freezer compartment 110 and the rapid freezer compartment 120, The freezing chamber 110 and the quick freezing chamber 120 are inserted and mounted on the inner side of the freezing chamber 110 and the rapid freezing chamber 120 so as to cool the freezing chamber 120 and the rapid freezing chamber 120 more smoothly.

또한, 냉동실(110)의 내측 후방과 급속냉동실(120)의 내측 후방은 냉기덕트(140)에 의해 연결되어, 냉동실(110) 및 급속냉동실(120)이 서로 연통된다.The inner rear of the freezing chamber 110 and the inner rear of the rapid freezing chamber 120 are connected by the cool air duct 140 so that the freezing chamber 110 and the rapid freezing chamber 120 are communicated with each other.

이때, 냉동실(110)의 내측 후방 즉, 냉동실측 냉기덕트 출입구(141)에는 정회전 및 역회전이 가능한 DC팬(150)이 설치되고, 급속냉동실(120)의 내측 후방 즉, 급속냉동실측 냉기덕트 출입구(142)에는 냉동실(110)로부터의 냉기는 유입되도록 하고 급속냉동실(120)의 냉기는 냉기덕트(140)를 통해 유출되지 못하도록 역류방지수단(160)이 설치된다.At this time, a DC fan 150 capable of forward rotation and reverse rotation is provided at an inner rear side of the freezing chamber 110, that is, a freezing chamber side cold air duct inlet / outlet 141. The DC fan 150 is disposed at an inner rear side of the rapid freezing chamber 120, A reverse flow preventing means 160 is installed in the duct inlet 142 so as to allow cool air from the freezing chamber 110 to be introduced and prevent the cool air from the rapid freezing chamber 120 from flowing out through the cool air duct 140.

구체적으로, 역류방지수단(160)은 DC팬(150)의 순환방향에 따라 개폐되는 전자댐퍼를 사용할 수 있지만, 이러한 전자댐퍼의 경우 비용 및 전력 소비 측면에서의 단점이 있으므로, 본 발명에서는 냉기덕트(140)를 통해 유동되는 냉기의 순환, 즉 자연대류에 의해 개폐되는 플랩(161)을 냉기덕트 입구(142)에 일측이 회동되도록 장착하여, 냉기가 급속냉동실(120) 측으로 유입될 때는 플랩(161)이 냉기덕트 입구(142)를 개방하고, 냉기가 냉동실(110) 측으로 유입될 때는 플랩(161)이 냉기덕트 입구(142)를 폐쇄한다.Specifically, the backflow prevention means 160 can use an electronic damper that is opened or closed according to the circulation direction of the DC fan 150. However, such an electronic damper has disadvantages in terms of cost and power consumption, The flap 161 which is opened and closed by the natural convection is installed so as to rotate on one side of the cold air duct inlet 142. When the cold air flows into the freezing compartment 120 side, 161 open the cool air duct inlet 142 and the cool air flows into the freezer compartment 110. The flap 161 closes the cool air duct inlet 142. [

또한, 냉장고 본체(100)의 중앙 전면에는 사용자가 온도 및 시간 또는 급속냉동기능 등의 설정사항을 선택하기 위한 버튼이 구비된 입력부(170)가 형성되어 있다.In addition, an input unit 170 having a button for selecting a setting item such as a temperature, a time, or a rapid freezing function is formed on the central front surface of the refrigerator main body 100.

그리고, 이 입력부(170)로부터 출력되는 신호에 의해 DC팬(150)이 구동되도록 제어신호를 출력하여 냉동실(110) 내부의 냉기가 냉기덕트(140)를 거쳐 급속냉동실(120)로 유입되도록 함으로써, 급속냉동실(120) 내부의 온도가 급격하게 하강되도록 제어신호를 출력하는 제어부(200)가 형성되어 있다. 따라서, 입력부(170)를 통해 급속냉동실의 온도가 급격히 하강되도록 하는 급속냉동기능이 선택되면, 제어부(200)에 의해 DC팬(150)이 작동하여 냉동실(110) 내부의 냉기를 급속냉동실(120) 측으로 유입되도록 함으로써, 단시간 내에 급속냉동실(120) 내부가 냉각된다.The DC fan 150 is driven by a signal outputted from the input unit 170 to output a control signal so that the cool air in the freezing chamber 110 flows into the quick freezing chamber 120 through the cool air duct 140 And a control unit 200 for outputting a control signal so that the temperature in the rapid freezing room 120 is rapidly lowered. The DC fan 150 is operated by the controller 200 to cool the inside of the freezer compartment 110 to the rapid freezer compartment 120 So that the interior of the rapid freezing chamber 120 is cooled within a short time.

한편, 냉동실(110) 및 급속냉동실(120) 내부에는 각각 냉동실(110) 내부의 온도를 감지하기 위한 냉동실 온도 감지 센서(180) 및 급속냉동실 온도 감지 센서(190)가 장착되어 있다.The freezer compartment temperature sensor 180 and the rapid freezer compartment temperature sensor 190 for sensing the temperature inside the freezer compartment 110 are installed in the freezer compartment 110 and the rapid freezer compartment 120, respectively.

이 온도 감지 센서들(180, 190)은 제어부(200)로 냉동실(110) 및 급속냉동실(120) 내부의 온도정보를 출력하고, 제어부(200)는 이 온도정보를 기초로 하여 급속냉동기능이 선택되지 않은 경우에, 냉동실(110) 및 급속냉동실(120)의 온도차가 발생하지 않도록 DC팬(150)의 회전방향을 제어함으로써, 냉동실(110) 및 급속냉동실(120)을 모두 정상적인 냉동실로서 사용가능하게 한다.The temperature sensors 180 and 190 output the temperature information in the freezer compartment 110 and the rapid freezer compartment 120 to the controller 200. The controller 200 performs rapid freezing The freezing chamber 110 and the rapid freezing chamber 120 are all used as a normal freezing chamber by controlling the rotating direction of the DC fan 150 so that the temperature difference between the freezing chamber 110 and the rapid freezing chamber 120 is not generated .

이하, 첨부된 도면을 참조하여 본 발명에 따른 냉장고의 급속냉동장치의 작용 및 효과를 설명한다.Hereinafter, the operation and effect of the quick freezing device of the refrigerator according to the present invention will be described with reference to the accompanying drawings.

먼저, 입력부(170)를 통해 사용자가 일반 냉동모드를 선택하면, 제어부(200)는 냉동실(110)의 설정온도와 냉동실 온도 감지 센서(180)를 통해 감지된 냉동실(110)의 실제온도를 비교하여, 냉동실(110)의 실제온도가 설정온도 이상이면, 압축기(미도시)를 구동하여 냉매싸이클이 순환되도록 하여 증발기(130)로부터 냉기가 생성되도록 한다.First, when the user selects the normal freezing mode through the input unit 170, the controller 200 compares the set temperature of the freezing room 110 with the actual temperature of the freezing room 110 sensed through the freezing room temperature sensing sensor 180 When the actual temperature of the freezing chamber 110 is higher than the set temperature, the compressor (not shown) is driven to circulate the refrigerant cycle to generate cold air from the evaporator 130.

이후, 냉동실 온도 감지 센서(180)를 통해 감지된 온도가 급속냉동실 온도 감지 센서(190)를 통해 감지된 온도보다 1℃이상 높은 경우, 제어부(200)는 DC팬(150)이 순방향으로 회전되도록 제어신호를 출력하여, 냉동실(110) 내측에서만 냉기가 순환되도록 함으로써 냉동실(110) 내부의 온도를 하강시킨다.If the temperature sensed by the freezer compartment temperature sensor 180 is higher than the sensed temperature by the freezer compartment temperature sensor 190, the controller 200 controls the DC fan 150 to rotate in the forward direction The control signal is outputted to cause the cool air to circulate only in the freezing chamber 110, thereby lowering the temperature inside the freezing chamber 110. [

반대로, 냉동실 온도 감지 센서(180)를 통해 감지된 온도가 급속냉동실 온도 감지 센서(190)를 통해 감지된 온도보다 1℃이상 낮은 경우, 제어부(200)는 DC팬(150)이 역방향으로 회전되도록 즉, 급속냉동실(120) 내측으로 냉동실(110)의 냉기가 유입되도록 제어신호를 출력한다.On the contrary, when the temperature sensed through the freezer compartment temperature sensor 180 is lower than the sensed temperature by the rapid freezer compartment temperature sensor 190, the controller 200 controls the DC fan 150 to rotate in the reverse direction That is, a control signal is output so that the cool air in the freezer compartment 110 flows into the rapid freezer compartment 120.

따라서, 일반 냉동모드인 경우에는 냉동실(110) 및 급속냉동실(120) 내부의 온도차가 거의 나지 않기 때문에, 냉동실(110) 및 급속냉동실(120)을 모두 냉동기능을 수행하는 냉동실로 사용할 수 있다.Therefore, in the normal freezing mode, the freezing chamber 110 and the rapid freezing chamber 120 can be used as a freezing chamber for performing a freezing function, since the temperature difference within the freezing chamber 110 and the rapid freezing chamber 120 hardly occurs.

한편, 입력부(170)를 통해 사용자가 급속 냉동모드를 선택하면, 제어부(200)는 급속냉동실 온도 감지 센서(190)를 통해 감지된 온도와 기 설정된 급속냉동실(120)의 설정온도를 비교하여, 급속냉동실(120)의 실제온도가 설정온도 이상인 경우 DC팬(150)이 역방향으로 회전되도록 즉, 급속냉동실(120) 내측으로 냉동실(110)의 냉기가 유입되도록 제어신호를 출력하여 급속냉동실(120)의 온도를 급격하게 하강시킨다. 따라서, 급속냉동이 필요한 식품을 급속냉동실(120) 내부에 수납하여 단시간에 이 식품을 급속냉각시킬 수 있다.Meanwhile, when the user selects the rapid freezing mode through the input unit 170, the controller 200 compares the sensed temperature of the rapid freezing room temperature sensor 190 with the preset temperature of the rapid freezing room 120, When the actual temperature of the rapid freezing chamber 120 is equal to or higher than the set temperature, the DC fan 150 outputs a control signal so that the DC fan 150 is rotated in the reverse direction, that is, the cold air of the freezing chamber 110 flows into the rapid freezing chamber 120, ) Is rapidly lowered. Therefore, the foodstuffs requiring rapid freezing can be stored in the rapid freezing chamber 120, so that the foodstuff can be rapidly cooled in a short time.

이후, 상기한 DC팬(150)의 역방향 회전에 의해 냉동실(110) 내부의 냉기가 급속냉동실(120) 측으로 유입됨에 따라 냉동실(110) 내부의 온도가 상승되는 문제가 발생하기 때문에, 냉동실 온도 감지 센서(180)를 통해 감지된 온도가 기 설정된 냉동실(110) 온도보다 높은 경우, 제어부(200)는 DC팬(150)이 순방향으로 회전되도록 제어신호를 출력하여 냉동실(110) 내측에서만 냉기가 유동되도록 함으로써, 냉동실(110) 내부의 온도를 하강시킨다.The temperature of the freezing chamber 110 is increased due to the flow of cool air in the freezing chamber 110 toward the freezing chamber 120 due to the reverse rotation of the DC fan 150, The control unit 200 outputs a control signal so that the DC fan 150 is rotated in the forward direction so that the cool air flows only in the freezing chamber 110. In this case, when the temperature sensed by the sensor 180 is higher than the predetermined freezing chamber temperature, So that the temperature inside the freezing chamber 110 is lowered.

따라서, 급속 냉동모드가 수행되더라도 냉동실 온도 감지 센서(180) 및 급속 냉동실 온도 감지 센서(190)를 통해 감지된 냉동실(110) 및 급속냉동실(120) 내부의 온도에 따라 DC팬(150)의 회전방향을 적절히 제어하여 냉동실(110) 내부의 온도가 설정온도 이하로 떨어지는 것을 방지할 수 있다.Therefore, even if the rapid freezing mode is performed, the rotation of the DC fan 150 is controlled according to the temperature inside the freezer compartment 110 and the rapid freezer compartment 120 sensed through the freezer compartment temperature sensor 180 and the rapid freezer compartment temperature sensor 190, The temperature in the freezing chamber 110 can be prevented from dropping below the set temperature.

상기한 바와 같이 본 발명은 서로 연통되도록 냉동실 및 급속냉동실을 형성하고, DC팬의 회전방향을 제어하여 급속냉동실 내부를 단시간에 냉각시킬 수 있는 효과가 있다.As described above, according to the present invention, the freezing chamber and the rapid freezing chamber are formed so as to communicate with each other, and the rotating direction of the DC fan is controlled to cool the rapid freezing chamber in a short time.

또한, 본 발명은 일반냉동모드인 경우, 냉동실 및 급속냉동실의 두 공간을 모두 일반 냉동실로 사용할 수 있는 효과가 있다.Further, in the general freezing mode, it is possible to use both the freezing room and the rapid freezing room as a general freezing room.
