이하, 본 고안에 따른 냉장고의 냉기공급장치에 대하여 첨부된 도면을 참조하여 그 구성요소를 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings for the cold air supply of the refrigerator according to the present invention will be described in detail the components as follows.
도 1 및 도 2를 참조하면, 도면부호 10 은 냉장고를 나타낸다. 냉장고(10)는 사절판(13)에 의해 냉동실(11)와 냉장실(12)로 구분되며, 냉동실(11)의 내측 후면부에는 증발기(14)가 설치된다. 사절판(13)의 내부에는 증발기(14)의 설치공간과 연통되는 상측덕트(15)가 형성되고, 냉장실(12)의 하면부 및 후면부의 내부에도 증발기(14)의 설치공간과 연통되는 하측덕트(16)가 형성된다. 상측덕트(15)의 일단부에는 냉기공급공(17)이 협소한 폭으로 길게 형성되어 내상의 선단부 상측에 하향되도록 형성되어 있고, 그 내부에는 크로스 팬(18)이 회전가능하게 축설되어 있다.1 and 2, reference numeral 10 denotes a refrigerator. The refrigerator 10 is divided into a freezer compartment 11 and a refrigerating compartment 12 by the trimming plate 13, and an evaporator 14 is installed at an inner rear side of the freezer compartment 11. An upper duct 15 is formed in the trimming plate 13 to communicate with the installation space of the evaporator 14, and a lower side communicated with the installation space of the evaporator 14 in the lower and rear portions of the refrigerating chamber 12. Duct 16 is formed. At one end of the upper duct 15, the cold air supply hole 17 is formed to have a narrow width so as to be lowered above the distal end of the inner phase, and a cross fan 18 is rotatably built therein.
크로스 팬(18)은 소정 직경과 길이를 지니며 원주면에 블래이드가 설치된 원통형 팬으로서 일단부가 구동모터(19)의 회전축과 연결되어 구동가능하게 설치된다.The cross fan 18 is a cylindrical fan having a predetermined diameter and length and a blade is installed on the circumferential surface thereof, and one end thereof is connected to the rotating shaft of the driving motor 19 to be driven.
하측덕트(16)의 일단부에는 냉기흡입공(20)이 냉기공급공(17)과 대향되도록 내상의 저면 선단부에 상측방향으로 형성되어 있다. 냉장실(12)의 전단면에는 스위치(21)가 장착된다.At one end of the lower duct 16, the cold air suction hole 20 is formed in the upper end portion of the bottom face of the inner phase so as to face the cold air supply hole 17. The switch 21 is mounted on the front end surface of the refrigerating chamber 12.
스위치(21)는 구동모터를 회전시키기 위한 스위치로서, 도어의 개폐동작시 도어의 내면에 의해 가압되거나 복원되도록 도어와 접하는 냉장고의 전면의 가장자리부분에 설치되어 있다. 또한, 스위치는 그 내부의 전극접점이 구동모터(19)와 전원케이블 사이를 전기적으로 통전되도록 연결되어 있기 때문에 냉장실 도어(22)의 개폐에 따라 스위칭동작에 의해 구동모터(19)로 공급되는 전류의 흐름방향을 바꾸어 구동모터(19)를 정·역회전시키게 된다.The switch 21 is a switch for rotating the drive motor, and is installed at an edge portion of the front surface of the refrigerator contacting the door so as to be pressed or restored by the inner surface of the door during the opening and closing operation of the door. In addition, the switch is connected to the electrical contact between the drive motor 19 and the power cable in the electrode contact therein, so that the current supplied to the drive motor 19 by the switching operation in accordance with the opening and closing of the refrigerating chamber door 22 The driving motor 19 is rotated forward and reverse by changing the flow direction of the.
이와 같이 구성된 본 고안에 따른 냉장고의 냉기공급장치에 대한 작용 및 그 효과를 첨부된 도면을 참조하여 설명하면 다음과 같다.Referring to the accompanying drawings, the operation and effects of the refrigerator air supply device of the present invention configured as described above are as follows.
도 1 및 도 2에 도시된 바와 같이, 냉장고(10)가 정상적인 작동상태 즉, 냉장실 도어(22)가 닫혀 있는 상태에서는 스위치(21)가 냉장실 도어(22)에 의해 눌려진 상태의 전극접속으로 구동모터(19)에 전력을 공급하기 때문에 구동모터(19)는 정회전을 하게 된다.1 and 2, when the refrigerator 10 is in a normal operating state, that is, when the refrigerator compartment door 22 is closed, the switch 21 is driven by the electrode connection in a state where the refrigerator 21 is pressed by the refrigerator compartment door 22. Since power is supplied to the motor 19, the drive motor 19 is to be rotated forward.
상술한 바와 같이 구동모터(19)가 정회전을 하게 되면, 크로스 팬(18)도 구동모터(19)의 회전방향으로 회전됨으로 냉장실(12)내에 유입되어 있는 공기를 흡입하여 증발기(14)쪽으로 귀환시키고, 증발기(14)의 설치공간에 있는 차가운 냉기가 하측덕트(16)를 따라 유도되어져 냉기흡입공(20)을 통하여 냉장실(12)로 분출되도록 함으로써 냉기의 순환 사이클이 신속하게 이루어지기 때문에 냉장실(12)을 급속으로 냉각시킬 수 있는 것이다.As described above, when the driving motor 19 rotates forward, the cross fan 18 also rotates in the rotational direction of the driving motor 19 to suck air introduced into the refrigerating chamber 12 toward the evaporator 14. Since the return of the cold air in the installation space of the evaporator 14 is guided along the lower duct 16 to be ejected into the refrigerating chamber 12 through the cold air suction hole 20, the circulation cycle of the cold air is made quickly. The refrigerating chamber 12 can be cooled rapidly.
만약, 사용자가 음식물을 수납하거나 꺼내기 위하여 냉장실 도어(22)를 개방하였을 때, 냉장실 도어(22)의 내측면에 의해 가압되어 있던 스위치(21)는 전방으로 돌출되면서 구동모터(19)에 연결되는 전력공급접점을 반대로 접속시킨다.When the user opens the refrigerating compartment door 22 to store or take out food, the switch 21 pressurized by the inner surface of the refrigerating compartment door 22 protrudes forward and is connected to the driving motor 19. Connect the power supply contacts in reverse.
전력공급접점이 반대로 접속되면, 그와 동시에 구동모터(19)는 역회전하게 됨으로 크로스 팬(18)도 구동모터(19)의 회전방향을 따라 회전된다.When the power supply contact is connected in reverse, at the same time, the drive motor 19 is reversed, so that the cross fan 18 is also rotated along the rotational direction of the drive motor 19.
상기 크로스 팬(18)이 회전되면, 증발기(14)의 설치공간에 있는 차가운 냉기는 증발기(14)의 설치공간으로부터 상측덕트(15)를 따라 냉기공급공(17)을 통하여 하방으로 수직되게 분사되어 냉기흡입공(20)으로 흡입되면서 냉장실(12)의 전면에 에어커튼이 형성된다.When the cross fan 18 is rotated, cold cold air in the installation space of the evaporator 14 is injected vertically downward through the cold air supply hole 17 along the upper duct 15 from the installation space of the evaporator 14. The air curtain is formed on the front surface of the refrigerating chamber 12 while being sucked into the cold air suction hole 20.
따라서, 냉장실(12)의 전면부에 에어커튼이 형성되면, 이미 냉장실(12)내에 공급되어 있는 냉기는 에어커튼에 의해 차단되기 때문에 외부로 유출되지 않으므로 냉기의 손실을 최소화시킬 수 있는 것이다.Therefore, if the air curtain is formed on the front surface of the refrigerating chamber 12, since the cold air already supplied in the refrigerating chamber 12 is blocked by the air curtain, it is possible to minimize the loss of cold air because it does not flow out.
전술한 바와 같이, 에어커튼이 형성되어 있는 상태에서 다시 냉장실 도어(22)를 닫으면, 스위치(21)가 다시 눌려지게 되어 구동모터(19)의 전극접점이 다시 정상상태로 접속됨으로 구동모터(19)는 회전하게 된다.As described above, when the refrigerating compartment door 22 is closed in the state where the air curtain is formed, the switch 21 is pressed again, and the electrode contact of the drive motor 19 is connected to the normal state again, thereby driving the drive motor 19. ) Rotates.
따라서, 크로스 팬(18) 역시 구동모터(19)의 회전에 따라 회전됨으로 냉기공급공(17)은 다시 냉장실(12)내의 냉기를 흡입하여 증발기(14)의 설치공간으로 귀환시키고, 증발기(14) 공간을 통과한 냉기는 하측덕트(16)를 따라 안내되어 냉기흡입공(20)을 통해 냉장실(12)속으로 분사됨으로 냉장실(12)을 급속으로 냉각시킬 수 있는 것이다.Therefore, the cross fan 18 is also rotated in accordance with the rotation of the drive motor 19, so the cold air supply hole 17 again sucks cold air in the refrigerating chamber 12, returns to the installation space of the evaporator 14, evaporator 14 The cold air passing through the space is guided along the lower duct 16 to be injected into the refrigerating chamber 12 through the cold air suction hole 20 to rapidly cool the refrigerating chamber 12.
이상에서 설명한 바와 같이, 본 고안은 냉장실(12)의 내측 상면 및 하면 전단부측에 각각 각각 냉기공급공(17)과 냉기흡입공(20)을 대향되게 형성시키고, 냉기공급공(17)내에 원통형상의 크로스 팬(18)을 설치하고, 냉장실 도어(22)의 개폐상태에 따라 크로스 팬(18)이 정·역방향으로 회전되어지도록 구동모터(19)를 정·역방향으로 구동시킴으로써 냉장실 도어(22)의 닫힌상태에서는 냉장실(12)내의 냉기 순환이 신속하게 이루어져 냉장실을 급속히 냉각시키고, 냉장실 도어(22)을 열었을 때는 구동모터(19)을 역회전시켜 냉장실(12)의 전면부에 에어커튼을 형성시켜 냉기손실을 최소화함으로써 냉장고의 냉각성능을 현저히 향상시킬 수 있는 효과가 있다.As described above, the present invention forms the cold air supply hole 17 and the cold air suction hole 20 on the inner upper surface and lower surface front end side of the refrigerating chamber 12, respectively, and has a cylindrical shape in the cold air supply hole 17. The refrigerator compartment door 22 by installing the upper cross fan 18 and driving the drive motor 19 in the forward and reverse directions so that the cross fan 18 is rotated in the forward and reverse directions according to the opening and closing state of the refrigerating compartment door 22. In the closed state, the cold air circulation in the refrigerating compartment 12 is rapidly formed, and the refrigerating compartment is rapidly cooled. When the refrigerating compartment door 22 is opened, the driving motor 19 is reversed to form an air curtain at the front side of the refrigerating compartment 12. By minimizing the loss of cold air there is an effect that can significantly improve the cooling performance of the refrigerator.
