본 발명은 냉장고의 냉기유로에 관한 것으로, 보다 자세하게는 냉동실과 냉장실로 냉기를 분배 공급하여 냉동, 냉장실의 온도가 소정의 설정온도 유지되도록 하는 냉기 순환시스템에 있어서 증발기에서 발생된 냉기 전체를 냉동실로 유입시켜 우선적으로 냉동실을 냉각시키고 냉동실을 순환한 냉기 전부가 냉장실로 유입되도록 하여 냉장실이 빠른 시간내에 설정온도에 이르도록 함으로써 냉장고의 냉각성능을 향상시킨 냉장고의 냉기공급 방법 및 장치에 관한 것이다. 일반적으로, 냉장고는 냉동실의 후방에 설치된 증발기에서 냉매가 주위로부터 열을 흡수하여 증발하는 과정에서 발생된 증발기 주위에 저온의 냉기를 일정한 분배비로 냉동실과 냉장실로 공급하여 냉동, 냉장실이 소정의 설정온도로 유지되도록 하는 구조를 취하고 있는 바, 이러한 냉장고의 일반적인 냉기 순환시스템을 간략하게 살펴보면 다음과 같다.The present invention relates to a cold air flow path of a refrigerator, and more particularly, to supply the cold air to the freezer compartment and the refrigerating compartment, and to supply the entire cold air generated in the evaporator to the freezer compartment in a cold air circulation system that maintains a predetermined set temperature of the freezer and refrigerator compartment. The present invention relates to a cold air supply method and apparatus for improving a refrigerator's cooling performance by allowing the refrigerator to cool in a freezer compartment and to allow all of the cold air circulating through the freezer compartment to be introduced into the refrigerating compartment so that the refrigerating compartment reaches a set temperature within a short time. In general, a refrigerator supplies low-temperature cold air to a freezing compartment and a refrigerating compartment at a constant distribution ratio around an evaporator generated by a refrigerant absorbing heat from the surroundings in an evaporator installed at a rear side of the freezing compartment, and thus the freezing and refrigerating compartment have a predetermined set temperature. Taking the structure to be maintained as, briefly look at the general cold air circulation system of such a refrigerator as follows.
먼저 제1도는 종래 냉장고의 내부구조를 보인 정면도이고, 제2도는 내지 제4도는 각각 제1도의 a-a선, b-b선 c-c선 단면도로서, 도시된 바와 같이 베리어(4)를 사이에 두고 냉동실(2)과 냉장실(3)로 구획된 냉장고 본체(1)의 냉동실(2) 후방에 장착된 증발기(5) 주위에서 열교환된 냉기는 송풍팬(6)에 의해 그 전방에 설치되어 있는 쉬라우드(7a) 및 그릴팬(7b)을 향해 토출되어 일부는 냉동실(2)로 유입되고 나머지의 냉기는 베리어(4)내에 형성된 냉장실 안내유로로 유입된 후 냉장실 덕트(8)로 유도되어 냉장실 덕트(8)의 유로상에 형성된 다수의 냉기토출공(9a, 9b, 9c)을 빠져나와 냉장실(3) 내부에 다단으로 설치된 선반(10a, 10b, 10c)에 의해 구분된 각 단으로 공급된다.First, FIG. 1 is a front view showing the internal structure of a conventional refrigerator, and FIGS. 2 to 4 are cross-sectional views taken along lines aa and bb of FIG. 1, respectively. The freezer compartment 2 is provided with the barrier 4 interposed therebetween. And heat exchanged around the evaporator 5 mounted behind the freezer compartment 2 of the refrigerator main body 1 divided into the refrigerator compartment 3 and the shroud 7a provided in front by the blower fan 6. ) And the grill pan 7b are discharged toward the freezer compartment 2 and the remaining cold air is introduced into the refrigerator compartment guide flow path formed in the barrier 4, and then led to the refrigerator compartment duct 8 to be connected to the refrigerator compartment duct 8. The plurality of cold air discharge holes 9a, 9b, and 9c formed on the flow paths are fed to the respective stages separated by the shelves 10a, 10b, and 10c installed in multiple stages in the refrigerating chamber 3.
한편, 상기와 같은 냉기 유로를 통해서 각기 냉동실(2)와 냉장실(3) 내부로 유입된 냉기는 각각 고내의 공기와 열교환을 행한 후 베리서(4)상에 형성되어 있는 냉동실 흡입유로(11) 및 냉장실 흡입유로(12)로 유입되어 증발기(5)측으로 귀환이 이루어지게 된다.On the other hand, the cold air introduced into the freezer compartment 2 and the refrigerating compartment 3 through the cold air passage as described above, respectively, after performing heat exchange with the air in the refrigerator, the freezer compartment suction passage 11 formed on the verifier 4. And it is introduced into the refrigerating chamber suction flow path 12 is made to return to the evaporator (5) side.
도면중 미설명 부호 S1과 S2는 각각 냉동실(2) 및 냉장실(3)의 고내온도를 감지하기 위한 센서이고, 화살표는 냉기의 흐름을 나타내고 있다.In the figure, reference numerals S1 and S2 are sensors for sensing the internal temperature of the freezing chamber 2 and the refrigerating chamber 3, respectively, and arrows indicate the flow of cold air.
이와 같은 구조 및 냉기 유로로 이루어진 종래의 냉장고에서는 송풍팬(6)에 의해 송풍되는 냉기의 총풍량을 일예로 1CMM(㎥/sec)라 할 때 냉동실과 냉장실로 분배되는 냉기는 냉동실로 70%에 해당하는 0.7MM이 유입되고, 나머지 30%인 0.3MM이 냉장실로 유입되도록 구성되어 있다. 따라서 상기한 바와 같은 냉기 분배량을 취하고 있는 종래의 냉장고에서는 그 냉장고가 냉동실의 설정온도(일예로 -18˚C)에 도달하면 냉장실의 온도에 관계없이 오프(OFF)되는 냉동실온도기준 제어방식이든 아니면 냉장고의 운전이 냉장실의 온도에 의해 온/오프되는 냉장실온도기준 제어방식이든 간에 냉장실로 유입되는 냉기의 양이 적기 때문에 냉장실의 온도를 소정의 설정온도로 낮추는데는 상당한 시간이 소요되고 있다.In a conventional refrigerator having such a structure and a cold air flow path, when the total air volume of the cold air blown by the blower fan 6 is 1 CMM (㎥ / sec), the cold air distributed to the freezer compartment and the refrigerating compartment is 70% as the freezer compartment. The corresponding 0.7MM flows in, and the remaining 30% 0.3MM flows into the fridge. Therefore, in the conventional refrigerator taking the above-mentioned amount of cold air distribution, if the refrigerator reaches the set temperature (for example, -18 ° C) of the freezer, the freezer temperature reference control method is turned off regardless of the temperature of the freezer. Alternatively, it is necessary to reduce the temperature of the refrigerator compartment to a predetermined set temperature because the amount of cold air flowing into the refrigerator compartment is small, regardless of whether the operation of the refrigerator is controlled based on the refrigerator compartment temperature based on / off by the temperature of the refrigerator compartment.
다시 말하면, 종래 냉장고의 냉기 분배비하세어는 냉장실로 유입되는 냉기의 양이 적어서 일예로 냉장실에 보관된 식품의 온도를 30˚C에서 10˚C까지 떨어뜨리는데 약 120분이 걸리게 되는 등의 냉각속도 및 냉각성능이 낮다는 문제점을 지니고 있다.In other words, the conventional cold air distribution ratio of the refrigerator has a small amount of cold air flowing into the refrigerating compartment, for example, it takes about 120 minutes to reduce the temperature of food stored in the refrigerating compartment from 30˚C to 10˚C. And low cooling performance.
따라서 본 발명은 종래 냉장고의 냉기 공급장치 및 냉기유로가 지니고 있는 상기 문제점을 해결하기 위한 것으로, 증발기에서 발생된 냉기 전체를 냉동실로 유입시켜 우선적으로 냉동실을 냉각시키고 냉동실을 순환한 냉기 전부가 베리어를 거쳐 냉장실로 유입되도록 하여 냉장실이 빠른 시간내에 그 설정온도에 이르도록 함으로써 냉장고의 냉각성능을 향상시킨 냉장고의 냉기공급 방법 및 장치를 제공함에 목적을 두고 있다.Therefore, the present invention is to solve the above problems with the cold air supply device and the cold air flow path of the conventional refrigerator, the entire cold air generated in the evaporator is introduced into the freezer compartment to cool the freezer first and all the cold air circulated through the freezer barrier It is an object of the present invention to provide a cold air supply method and apparatus for a refrigerator which improves the cooling performance of the refrigerator by allowing the refrigerator to reach the set temperature within a short time by allowing the refrigerator to enter the refrigerator.
본 발명의 냉기공급 방법은 증발기에서 냉각된 냉기 전체를 냉동실로 유입시키고, 냉동실을 순환한 냉기는 베이러내의 냉장실 냉기 토출유로로 유입시켜 냉기조절 장치를 거쳐 냉장실로 유입시킨 후 냉장실을 순환한 온도가 상승된 냉기는 베리어상에 형성된 냉장실 흡입유로를 통해서 증발기로 귀환되도록 한 데에 기술적 특징이 있다.In the cold air supply method of the present invention, the entire cold air cooled in the evaporator is introduced into the freezer compartment, and the cold air circulated through the freezer compartment flows into the cold compartment discharged air flow path in the refrigerator compartment, and then enters the cold compartment through the cold air control device, and then circulates the cold compartment. The elevated cold air is a technical feature to be returned to the evaporator through the refrigerating chamber suction flow path formed on the barrier.
이 때, 냉동실을 순환한 후 베리어를 거쳐 냉장실로 유입되는 냉기는 냉동, 냉장실 온도를 감지하는 센서에 의해서 구동되는 냉기조절 장치에 의해서 그 유입량에 대한 제어가 이루어지게 된다. 한편, 상기 본 발명의 냉기공급 방법을 수행하는 데 적합한 장치로서의 본발명 냉기공급 장치는 증발기에서 발생된 냉기 전체를 냉동실로 유입시키는 냉동실 냉기 토출유로와 베리어상에 형성되는 냉동실을 순환한 냉기를 냉장실로 유입시키기 위한 냉장실 냉기토출 유로와 냉동실과 냉장실에 설치되어 고내의 온도를 감지하는 센서와 상기 냉장실 냉기토출 유로상에 설치되어 상기 센서의 감지신호에 의해 구동되는 냉기조절 장치와 냉기조절 장치로부터 증발기로 이어진 냉기통로를 구성하는 냉동실 흡입유로 및 베리어상에 형성되어 냉장실을 순환한 공기를 증발기측으로 귀환 시키는 냉장실 흡입유로로 이루어져 있다.At this time, the cold air flowing into the refrigerating compartment after circulating the freezer compartment is controlled by the cold air control device driven by the sensor for detecting the temperature of the refrigerating and refrigerating compartment. On the other hand, the present invention cold air supply device as a device suitable for performing the cold air supply method of the present invention is a cold air storage chamber circulated through the freezer compartment cold air discharge flow path for introducing the entire cold air generated in the evaporator to the freezer compartment and the freezer compartment formed on the barrier Evaporator from a cold air control device and a cold air control device installed in a refrigerating chamber cold air discharge passage and a freezer compartment and a refrigerating compartment for sensing the temperature in the refrigerator, and installed on the refrigerating compartment cold air discharge passage and driven by a detection signal of the sensor. It consists of a freezer compartment suction passage constituting the cold air passage leading to the refrigerator and a cold compartment suction passage formed on the barrier to return the air circulated in the refrigerating compartment to the evaporator side.

First, FIG. 5 is a front view showing the internal structure of the refrigerator of the present invention, and FIGS. 6 and 7 are cross-sectional views taken along line AA and BB of FIG. 5, respectively, and FIG. FIG. 5 is a cross-sectional view taken along line CC of FIG. In the drawings, the same parts as in the conventional construction are denoted by the same reference numerals as in FIGS. 1 to 4. As shown in the drawing, the cold air generated around the evaporator 5 by the operation of the refrigerator passes through the shroud 7a and the grill pan 7b that are provided in front of the whole by the driving of the blower fan 6. 2) flows into. The cold air flowing into the freezer compartment 2 and circulating in the refrigerator flows into the refrigerator compartment discharge passage 21 formed on the insulation barrier 4 between the freezer compartment 2 and the refrigerator compartment 3. At this time, the refrigerating chamber discharge passage 21 has the other end thereof connected to the refrigerating chamber 3, and the cool air control device 22 is installed on the flow path 21, and thus the amount of cold air flowing into the refrigerating chamber 3 is reduced. Control is made.
그리고, 상기 냉기조절 장치(22)의 후방으로는 제8도에서와 같이 증발기(5)측으로 이어진 냉동실 흡입유로(23)가 형성되어 있어 냉기조절 장치(22)의 구동상태에 따라 냉동실(2)을 순환한 후 냉장실 토출유로(21)로 유입된 냉기는 증발기(5)측으로 흘러들 수도 있게된다. 즉, 냉기조절 장치(22)의 구동에 의해 회동하는 냉기 차단막(22a)의 위치에 따라 냉장실 토출유로(21)내를 유동하는 냉기는 냉장실(3)로 향하거나(냉기 차단막이 P1 상태일 때) 증발기 (5)측으로 귀환(냉기 차단막이 P2 상태일 때)하게 된다. 이 때, 냉기조절 장치(22)의 구동은 냉동, 냉장실(2)(3)내에 설치되어 고내의 온도를 감지하는 센서(S1)(S2)로부터 인가되는 감지신호에 의해서 이루어지게 된다. 다음, 상기 냉기조절장치(22)를 거쳐 냉장실(3) 내부로 유입된 냉기는 고내의 상대적으로 높은 공기와 열교환을 행한 후 베리어(4)상에 형성되어 있는 냉장실 흡입유로(24)로 유입된 후 증발기(5)로 향하게 된다.In addition, a freezer compartment suction flow path 23 extending to the evaporator 5 side is formed at the rear of the cold air conditioner 22, so that the freezer compartment 2 is driven according to the driving state of the cold air conditioner 22. After circulation, the cold air introduced into the refrigerating chamber discharge passage 21 may flow to the evaporator 5 side. That is, the cold air flowing in the refrigerating chamber discharge passage 21 according to the position of the cold air blocking film 22a rotated by the operation of the cold air conditioner 22 is directed to the refrigerating chamber 3 (when the cold blocking film is in the P1 state). ) To the evaporator 5 side (when the cold air barrier is in the P2 state). At this time, the driving of the cold air conditioner 22 is made by a detection signal applied from the sensors S1 and S2 installed in the freezing and refrigerating chambers 2 and 3 to sense the temperature in the refrigerator. Next, the cold air introduced into the refrigerating chamber 3 through the cold air conditioner 22 undergoes heat exchange with relatively high air in the refrigerator, and then flows into the refrigerating chamber suction flow path 24 formed on the barrier 4. It is then directed to the evaporator (5).
이와 같은 본 발명의 냉기 유로에 의한 냉장고의 냉각 수행과정을 살펴보면 다음과 같다.Looking at the cooling process of the refrigerator by the cold air flow path of the present invention as follows.
먼저, 냉동실온도기준 제어방식의 냉장고인 경우, 냉동실(3)의 온도가 -18˚C에 도달하기 전에 냉장실(3)이 그 설정온도(일예로 3˚C)에 도달한 경우에는 냉장실 온도센서(S2)의 감지에 의해 냉기조절 장치(22)가 작동하여 냉기 차단막(22a)이 P1위치에서 P2위치로 회전하여 냉장실(3)로 유입되는 냉기유로가 차단됨에 따라 냉동실(2)을 순환한 냉기는 냉동실 흡입유로(23)에 안내되어 증발기(5)로 향하게 된다.First, in the case of the refrigerator of the freezer temperature reference control method, the refrigerator compartment temperature sensor when the refrigerator compartment 3 reaches its set temperature (for example, 3˚C) before the temperature of the freezer compartment 3 reaches -18 ° C. The cold air control device 22 operates by detecting the S2, and the cold air blocking film 22a rotates from the P1 position to the P2 position to circulate the freezing chamber 2 as the cold air flow path flowing into the refrigerating chamber 3 is blocked. Cold air is guided to the freezer compartment suction flow path 23 to the evaporator (5).
한편, 냉장실 온도기준 제어방식의 냉장고인 경우에는 제10도의 냉기조절 장치 구동회로도에서와 같이 냉장실(3)의 온도가 그 설정온도인 3˚C에 도달하였을 때 냉동실의 온도센서(S1)의 감지에 의해 냉동실(2)의 온도가 -18˚C이하라고 감지되면 냉장고의 운전을 오프하고, 그 설정온도에 도달하지 않은 것으로 감지되면 냉기조절 장치(22)의 구동 모터를 작동시켜 냉기 차단막(22a)을 P1위치에서 P2위치로 회전시킴에 의해 냉장실(3)로 유입되는 냉기유로를 차단하여 냉동실(2)을 순환한 냉기가 직접 증발기(5)로 향하도록 한다. 다음, 냉동실(2)의 온도가 -18˚C이하로 떨어지게 되면 냉장고의 운전을 오프시킨다. 상술한 바와 같이 본 발명에서는 냉장고의 전체 풍량을 우선적으로 냉동실로 유입시켜 냉장실의 온도를 소정의 설정온도로 낮추도록 한 냉기순환 유로구조로 이루어져 있음에 따라 냉장, 냉동실이 빠른 시간내에 그 설정온도에 도달하게 되어 냉장고의 냉각성능이 향상됨과 아울러 소비전력이 절감되는 이점이 있다.On the other hand, in the case of the refrigerator of the refrigerator control temperature reference method, as shown in the driving circuit diagram of the cooling apparatus of FIG. 10, when the temperature of the refrigerator compartment 3 reaches the set temperature 3 ° C, the detection of the temperature sensor S1 of the freezer compartment When the freezer compartment 2 detects that the temperature of the freezer compartment 2 is -18 ° C or lower, the operation of the refrigerator is turned off, and when it is detected that the set temperature has not been reached, the drive motor of the cold air conditioner 22 is operated to operate the cold air barrier 22a. By rotating) from the P1 position to the P2 position, the cold air flow path flowing into the refrigerating chamber 3 is cut off so that the cold air circulating in the freezing chamber 2 is directly directed to the evaporator 5. Next, when the temperature of the freezer compartment 2 drops below -18˚C, the operation of the refrigerator is turned off. As described above, in the present invention, the cold air flow passage structure is configured to lower the temperature of the refrigerating chamber to a predetermined set temperature by first introducing the entire air volume of the refrigerator into the freezing chamber. By reaching the cooling performance of the refrigerator is improved and the power consumption is reduced.
