본 고안은 냉장고의 냉기 조절장치에 관한 것으로서, 특히 냉동실 후방에 냉각기가 설치되어 여기에서 발생된 냉기가 냉장실로 순환되는 간냉식 냉장고에 있어서, 조절노브에 의해 냉장실로 순환되는 냉기를 직접 조절할 수 있도록한 냉장고의 냉기 조절장치에 관한 것이다.The present invention relates to a cold air conditioner of the refrigerator, and in particular, in the intercooled refrigerator in which a cooler is installed at the rear of the freezer compartment to circulate the cold air generated in the refrigerator compartment, the control knob can directly control the cold air circulated to the cold compartment. It relates to a cold air conditioner of the refrigerator.

간냉식 냉장고의 경우에는 냉장실에 별도의 냉각기를 설치하지 않고 냉동실 후방에 냉각기를 설치하여 여기에서 발생하는 냉기를 냉기순환팬에 의해 냉장실로 순환되도록 하였다. 따라서 냉장실로 순환되는 냉기를 필요에 따라 조절해줘야 되었던 바, 종래에는 냉동실 후방에 서로 결합된 채 설치되는 후방커버와 절연체 사이에 형성된 냉기통로에 이를 개폐하는 댐퍼를 설치하고 상기 댐퍼의 개폐판의 열림각도를 조절하는 조절노브를 후방커버 전방, 즉 냉동실에 돌출 되도록 결합하여 상기 조절노브를 회전시키면 이와 연동되어 댐퍼의 개폐판이 작동되도록 하였다. 따라서 냉기를 조절하는 조절장치의 구조가 매우 복잡하여 설치작업이 번거로울 뿐만 아니라 별도의 댐퍼가 추가되어 생산단가를 상승시키는 요인이 되었다.In the case of the intercooled refrigerator, a cooler is installed at the rear of the freezing compartment without installing a separate cooler in the refrigerating compartment so that the cold air generated therein is circulated to the refrigerating compartment by a cold air circulation fan. Therefore, the cold air circulated to the refrigerating chamber had to be adjusted as necessary. In the related art, a damper for opening and closing the damper for opening and closing the damper opening and closing the damper is installed in the cold air passage formed between the rear cover and the insulator installed in the rear of the freezer compartment. Combining the control knob to adjust the angle so as to protrude to the front of the rear cover, that is, the freezer compartment when the control knob is rotated in conjunction with this to operate the opening and closing plate of the damper. Therefore, the structure of the regulating device to control the cold air is very complicated, and the installation work is cumbersome, and additional dampers are added to increase the production cost.

또한 조절노브를 돌리면 이와 연동되는 댐퍼의 개폐판이 작동하기 때문에 이들의 연결상태가 양호하지 못할 경우에는 냉기의 조절이 불확실하게 되므로 냉장고의 신뢰성을 저하시키는 문제점이 있었다.In addition, when the control knob is turned, the opening and closing plate of the damper interlocked with it operates, so if the connection state thereof is not good, there is a problem of deteriorating the reliability of the refrigerator because the control of cold air is uncertain.

본 고안의 목적은 상기와 같은 문제점을 해결하기 위하여 냉동실 후방에 설치되는 냉동실 후방커버에 마련된 냉기통로 상부에 냉기 순환공을 가진 공정판에 상기 냉기순환공과 대응되는 또 다른 냉기순환공을 가진 조절노브를 후방커버 전면에 약간 노출되게 결합하여 냉각기에서 차거워진 냉기가 냉기순환팬에 의해 냉기통로를 따라 냉장실로 순환될 때 조절노브를 돌려주면 바로 냉기가 조절될 수 있으므로 냉기 조절장치의 구조가 매우 간단해지고, 또한 냉기조절이 보다 확실하게 이루어지는 냉장고의 냉기 조절장치를 제공함에 있다.An object of the present invention is to adjust the knob having another cold air circulation hole corresponding to the cold air circulation hole on the process plate having a cold air circulation hole on the upper portion of the cold air passage provided in the rear cover of the freezer compartment to solve the above problems Is slightly exposed to the front of the rear cover, and when the cold chilled in the cooler is circulated by the cold circulation fan to the refrigerating chamber along the cold passage, turning the control knob can control the cold air immediately. The present invention also provides a cold air conditioner for a refrigerator in which cold air is more reliably controlled.

Exposed to the freezer compartment (2) through this area is indicated the amount of cold air is controlled.

그리고 조절노브(16)의 스토퍼(20)는 하부 고정판(12')의 냉기 순환공(15)의 일측 가장자리에 끼워져 위치하게 된다. 이때 하부 고정판의 냉기 순환공(15)과 조절노브의 냉기 순환공(18)이 일치됨은 물론이다.In addition, the stopper 20 of the adjustment knob 16 is positioned at one edge of the cold air circulation hole 15 of the lower fixing plate 12 ′. At this time, the cold air circulation hole 15 of the lower fixing plate and the cold air circulation hole 18 of the adjustment knob is a matter of course.

이와같이 구성된 본 고안은 냉장고(1)를 가동하게 되면 냉각기(5)에서 발생된 냉기가 냉기순환팬(6)에 의해 절연체(7)의 냉기유입구(10)를 통해 유입되어 많은 양의 냉기는 후방커버(8)의 냉기유출공(11)을 통해 냉동실(2)로 유입된다.When the refrigerator 1 operates, the present invention configured as described above allows the cool air generated in the cooler 5 to flow through the cold air inlet 10 of the insulator 7 by the cold air circulation fan 6 so that a large amount of cold air is rearward. It flows into the freezing chamber 2 through the cold air outlet 11 of the cover (8).

그리고 나머지 적은 양의 냉기는 냉기통로(9)상부에 결합된 조절노브(16)의 냉기 순환공(18)이나 하부 고정판(12')의 냉기 순환공(15)(15')을 통해 냉기통로(9)를 따라 냉장실(3)로 순환되게 된다. 이때 냉동실(2)로 노출된 조절노브(16)를 돌려주게 되면 조절노브의 냉기순환공(18)과 하부고정판의 냉기순환공(15)이 서로 엇갈리게 맞춰지면서 이에 따라 냉장실(3)로 순환되는 냉기의 양이 조절되게 된다. 이때 조절노브(16)의 하면 스토퍼(20)에 의해 조절노브(16)가 하부 고정판의 냉기 순환공(15)의 범위내에서만 돌려지게 된다. 그리고 조절노브(16)의 냉기조절 상태에 관계없이 하부 고정판의 냉기 순환공(15')을 통해서 소량을 냉기가 계속해서 냉장식(3)로 순환됨은 물론이다.The remaining small amount of cold air passes through the cold air circulation holes 18 of the control knob 16 coupled to the upper part of the cold air passage 9 or the cold air circulation holes 15 and 15 'of the lower fixing plate 12'. It is circulated to the refrigerating chamber 3 along (9). At this time, when the control knob 16 exposed to the freezing chamber 2 is returned, the cold air circulation hole 18 of the adjustment knob 18 and the cold air circulation hole 15 of the lower fixing plate are alternately matched with each other, thereby being circulated to the refrigerating compartment 3. The amount of cold is controlled. At this time, the adjustment knob 16 is turned only by the stopper 20 of the adjustment knob 16 within the range of the cold air circulation hole 15 of the lower fixing plate. In addition, regardless of the cold air control state of the adjusting knob 16, a small amount of cold air continues to be circulated to the refrigeration type (3) through the cold air circulation hole (15 ') of the lower fixed plate.

이와같이 본 고안은 간냉식 냉장고에 있어서, 냉장실(3)로 순환되는 냉기를 조절노브(16)에 의해서 직접 조절할 수 있으므로 냉기 조절 동작이 간단하면서도 냉기 조절이 보다 확실하고, 또한 구조가 간단하여 설치작업이 용이하며 생산단가도 절감시킬 수 있는 특징을 지닌 것이다.Thus, in the present invention, in the intercooled refrigerator, since the cold air circulated to the refrigerating compartment 3 can be directly controlled by the adjusting knob 16, the cold air control operation is simple, but the cold air control is more certain, and the structure is simple. It is easy and has the features to reduce the production cost.
