본 발명은 냉장고의 온도제어에 관한 것으로, 특히 냉장실의 냉장상태에 따라 압축기의 온/오프점을 증가 또는 하강시켜 냉장실의 부하대응속도의 저하를 방지할 수 있는 냉장고의 온도제어방법에 관한 것이다.The present invention relates to temperature control of a refrigerator, and more particularly, to a temperature control method of a refrigerator capable of preventing a decrease in load response speed of a refrigerator by increasing or decreasing an on / off point of a compressor according to a refrigeration state of a refrigerator.

제1도는 온도제어를 위한 장치를 구비한 냉장고의 단면도로서, 이에 도시한 바와같이 압축기(1)와, 냉동실의 열교환을 위한 증발기(2)와, 상기 증발기(2)로 부터의 냉기를 냉동실로 공급하는 냉동실 팬(3)과, 제상온도를 감지하는 제상센서(4)와, 냉동실의 온도를 감지하는 냉동센서(5)와, 냉기유입구(6)를 통하여 냉동실로부터 냉장실로 유입되는 냉기의 량을 조절하는 냉장실 댐퍼(7)와, 상기 댐퍼(7)를 통하여 전달된 냉기를 각 칸으로 안내하는 냉기토출구(8)(9)(10)와, 각 선반(11)(12)(13)으로 구분되어 3단으로 구성된 상단칸(14), 중단칸(15) 및 하단칸(16)의 온도를 감지하는 제1,제2 및 제3냉장센서(17)(18)(19)로 구성된다.1 is a cross-sectional view of a refrigerator having a device for temperature control, as shown therein, a compressor 1, an evaporator 2 for heat exchange of a freezer compartment, and cold air from the evaporator 2 to a freezer compartment. The amount of cold air flowing into the refrigerating chamber from the freezing chamber through the freezing chamber fan 3 to be supplied, the defrost sensor 4 for detecting the defrost temperature, the freezing sensor 5 for detecting the temperature of the freezing chamber, and the cold air inlet 6 Refrigerator chamber damper (7) for controlling the cold air discharge port (8) (9) (10) and each shelf (11) (12) (13) for guiding the cold air delivered through the damper (7) to each compartment. It consists of first, second and third refrigeration sensor (17) (18) (19) for detecting the temperature of the upper compartment 14, the stop compartment (15) and the lower compartment (16), which are divided into three stages. do.

이와같이 구성된 냉장고 온도제어를 위한 장치를 이용한 종래의 온도제어 방법을 제2도를 참조하여 설명하면 다음과 같다.The conventional temperature control method using the apparatus for temperature control of the refrigerator configured as described above will be described with reference to FIG. 2.

냉동센서(5)에서는 냉동실의 온도를 검출하고 이 검출온도가 기 설정된 압축기(1)의 차단점보다 낮을 경우 냉동실의 냉동상태가 만족되었다고 판단하여 압축기(1)와 냉동실 팬(3)을 정지시켜 냉각을 중단한다. 반대로 냉동실 온도가 압축기의 동작점보다 높을 경우 냉동실의 냉동상태를 불만족으로 판단하여 상기 압축기(1)와 냉동실 팬(3)을 구동시켜 냉동실을 냉각시킴으로써 냉동실제어를 수행한다.The freezing sensor 5 detects the temperature of the freezer compartment and determines that the freezing state of the freezer compartment is satisfied when the detected temperature is lower than the preset cutoff point of the compressor 1 and stops the compressor 1 and the freezer compartment fan 3. Stop cooling. On the contrary, when the freezer compartment temperature is higher than the operating point of the compressor, the freezer compartment is determined to be unsatisfactory and the freezer compartment is controlled by driving the compressor 1 and the freezer compartment fan 3 to cool the freezer compartment.

또한, 냉장실의 온도를 제어하기 위해 냉장센서(17)(18)(19)로부터 검출한 상단, 중단 및 하단칸(14)(15)(16)의 검출온도를 평균하여, 이 평균한 냉장실의 온도의 평균치가 기 설정된 상기 냉장실 댐퍼(7)의 전폐점보다 낮으면 냉장실로 공급되는 냉기를 차단하고, 반대로 상기 평균치가 상기 냉장실 댐퍼(7)의 전개점보다 높으면 이 냉장실 댐퍼(7)를 전개하여 냉동실로 부터의 냉기를 냉장실로 공급하여 냉장실의 온도를 조절하게 된다.In addition, in order to control the temperature of the refrigerating chamber, the detection temperatures of the upper, middle, and lower compartments 14, 15, and 16 detected from the refrigerating sensors 17, 18, and 19 are averaged to determine the average of the refrigerating chamber. If the average value of the temperature is lower than the predetermined closing point of the refrigerating chamber damper 7, the cold air supplied to the refrigerating chamber is cut off, and conversely, if the average value is higher than the developing point of the refrigerating chamber damper 7, the refrigerating chamber damper 7 is developed. By supplying the cold air from the freezer to the refrigerating compartment to control the temperature of the refrigerating compartment.

이와같이, 종래에는 냉동센서(5)의 감지결과에 따라 압축기(1)와 냉동실 팬(3)을 동작 및 중지시켜 냉동실의 온도제어를 수행하고, 또한 냉장실의 온도제어는 냉장센서(17)(18)(19)의 감지결과에 따라 상기 냉동실의 냉기를 공급 및 차단시킴으로써 이루어지게 되어 냉장실의 냉각능력은 냉동실의 냉각된 냉기에 의존하게 된다.As described above, in the related art, the temperature control of the freezer compartment is performed by operating and stopping the compressor 1 and the freezer compartment fan 3 according to the detection result of the freezing sensor 5, and the temperature control of the refrigerating compartment is performed by the refrigerating sensor 17 (18). According to the detection result of (19) is made by supplying and blocking the cold air of the freezer compartment, the cooling capacity of the refrigerating compartment is dependent on the cooled cold air of the freezer compartment.

따라서, 냉동실이 만족된 상태에서는 냉각력을 결정하는 압축기(1)와 냉동실 팬(3)이 이미 정지된 상태이므로 냉장실 불만족시 아무리 냉장실로 유입되는 냉기량을 조절하는 냉장실 댐퍼(7)를 전개해도 냉장실의 온도 조절에는 별다른 영향을 주지 못하는 문제점이 발생되고, 이에따라 전체적인 냉장고의 온도가 냉동실 중심으로 제어됨으로 인하여 부하대응이 신속히 이루어지지 못하는 문제점이 있었다.Therefore, in the state where the freezer is satisfied, since the compressor 1 and the freezer fan 3 which determine the cooling power are already stopped, even if the refrigerator compartment damper 7 which controls the amount of cold air flowing into the refrigerating chamber is unsatisfactory even when the refrigerator compartment is unsatisfactory. There is a problem that does not affect the temperature control of the refrigerating chamber, there is a problem that the load response is not made quickly because the temperature of the entire refrigerator is controlled by the center of the freezer.

이와같은 문제점을 해결하기 위한 본 발명의 목적은 냉장실의 냉장센서의 검출결과로 압축기와 냉동실 팬의 동작 또는 차단을 결정하고, 또한 냉동실의 온도변화를 제상센서를 이용하여 압축기와 냉동실 팬의 동작 및 차단점을 일정값으로 상승 또는 하강시킬 수 있도록 한 냉장고의 온도제어 방법을 제공함에 있다.An object of the present invention for solving the above problems is to determine the operation or shut-down of the compressor and the freezer fan as a result of the detection of the refrigerating sensor of the refrigerating chamber, and to operate the compressor and the freezer fan using the defrost sensor The present invention provides a method for controlling the temperature of a refrigerator to raise or lower the breaking point to a predetermined value.

상기 목적을 달성하기 위한 본 발명의 방법은, 냉장실에 설치된 제1,제2 및 제3냉장센서로부터 고내온도를 감지하여, 그 감지온도의 평균치를 계산하는 제1단계와, 상기 제1단계에서 구한 평균치가 마이콤내에 설정된 설정치보다 낮을 경우, 압축기와 냉동실 팬을 정지시켜 냉각을 중단하는 제2단계와, 상기 제1단계에서 구한 평균치가 기 설정치보다 높을 경우, 증발기에 설치된 제상센서의 감지온도가 냉동만족온도 이상이면 상기 설정치를 하강시키고, 제상센서의 감지온도가 냉동만족온도 이하이면 상기 설정치를 상승시키는 제3단계로 이루어진다.The method of the present invention for achieving the above object, the first step of detecting the internal temperature from the first, second and third refrigeration sensors installed in the refrigerating chamber, and calculating the average value of the detected temperature, in the first step When the average value obtained is lower than the set value set in the microcomputer, the second step of stopping the cooling by stopping the compressor and the freezer fan; and when the average value obtained in the first step is higher than the preset value, the detected temperature of the defrost sensor installed in the evaporator is If the freezing satisfaction temperature is higher than the set value is lowered, if the detection temperature of the defrosting sensor is lower than the freezing temperature, the third step of raising the set value.

상기한 바와같은 본 발명의 방법에 따른 작용 및 효과를 제1도 및 제3도를 참조하여 설명하면 다음과 같다.The operation and effect according to the method of the present invention as described above with reference to FIGS. 1 and 3 are as follows.

먼저, 냉장실의 제1,제2 및 제3 냉장센서(17)(18)(19)로부터 검출한 상단, 중단 및 하단칸(14)(15)(16)의 온도를 검출하고(ST1), 이 검출온도를 평균하여 이 평균치가 마이콤내에 기 설정된 설정치 즉, 압축기(1)의 동작 차단점보다 낮으면 이 압축기(1)와 냉동실 팬(3)의 구동을 정지시켜 냉각을 중단시키게 되고 (ST2,ST3,ST4), 반대로 상기 검출한 냉장실 평균치가 압축기(1)의 동작 개시점보다 높다고 판단되면(ST5) 이 압축기(1)와 냉동실 팬(3)을 구동하여 냉장실을 냉각시키게 된다(ST10).First, the temperatures of the upper, middle and lower compartments 14, 15 and 16 detected from the first, second and third refrigeration sensors 17, 18 and 19 of the refrigerating compartment are detected (ST1), If the average temperature is lower than the set value set in the microcomputer, that is, the operation cutoff point of the compressor 1, the compressor 1 and the freezer fan 3 are stopped to stop cooling (ST2). On the contrary, if it is determined that the detected mean value of the refrigerator compartment is higher than the operation start point of the compressor 1 (ST5), the compressor 1 and the freezer compartment 3 are driven to cool the refrigerator compartment (ST10). .

이와같이 종래와는 달리 냉장실의 냉각상태에 따라 압축기(1)와 팬(3)의 동작여부를 결정하게 됨으로써 냉동실의 냉각상태는 불만족이며, 이를 보상하기위해 상기한 바와같이 제1,제2,제3 냉장센서(17)(18)(19)로 부터의 감지결과에 의해 압축기(1)를 구동하게 되는 단계(ST10)의 앞단계로, 제상센서(4)로부터 온도를 감지하게 되며, 이는 압축기(1)의 구동시점이 냉동실의 온도와 거의 평형이 되기 때문에 종래의 냉동센서 없이도 냉동실 온도의 간접감지를 가능하게 한다.As described above, the operation of the compressor 1 and the fan 3 is determined according to the cooling state of the refrigerating compartment, so that the cooling state of the freezing compartment is unsatisfactory. 3 Prior to the step ST10 in which the compressor 1 is driven by the detection result from the refrigeration sensors 17, 18 and 19, the temperature is detected from the defrost sensor 4, which is a compressor. Since the driving point of (1) is almost in equilibrium with the temperature of the freezer compartment, it is possible to indirectly detect the freezer compartment temperature without a conventional freezing sensor.

이를 상세히 설명하면, 제상센서(4)로 검출한 온도가, 기 설정된 냉동실의 냉동만족온도 이상이 되어 냉동실 불만족 상태가 되면 상기 압축기(1)와 냉동실 팬(3)의 동작/차단점을 1℃정도 낮추어 주고 이로 인하여 냉동실의 냉각상태는 보상이 된다(ST5,ST7).In detail, when the temperature detected by the defrost sensor 4 becomes higher than the preset freezing satisfaction temperature of the freezer compartment and becomes unsatisfactory in the freezer compartment, the operation / break point of the compressor 1 and the freezer compartment fan 3 is 1 ° C. The lower the degree, thereby compensating the cooling state of the freezer (ST5, ST7).

이후, 냉각이 실시되어 냉장실의 평균치 온도가 상기 보상된 압축기(1)와 냉동실 팬(3)의 차단점에 도달하게 되면 압축기(1)를 오프시키며, 다음으로 압축기(1)의 동작점에서 제상센서의 감지결과를 읽어 냉동실이 냉동차단온도 이하로 만족되면 현재 압축기의 동작/차단점을 1℃정도 상승시킴으로써, 원래의 보상전의 동작/차단점으로 복귀된다(ST8,ST9).Thereafter, cooling is performed to turn off the compressor 1 when the average temperature of the refrigerating chamber reaches the cutoff point between the compensated compressor 1 and the freezing chamber fan 3, and then defrosts at the operating point of the compressor 1. If the freezing chamber is satisfied below the freezing cutoff temperature by reading the detection result of the sensor, the operation / cutting point of the current compressor is increased by about 1 ° C., thereby returning to the operation / cutting point before the original compensation (ST8, ST9).

이상에서 상세히 설명한 바와같이, 본 발명의 제어방법은 냉장실의 냉장센서로부터 검출한 온도에 따라 압축기 및 냉동실 팬의 동작 또는 차단을 결정하여 냉각을 실시함으로써 냉장실의 냉각상태를 충분히 만족시키고, 또한 냉동실의 냉동기준 온도를 상승 또는 하강시킴으로써 보상을 하여 신속한 부하대응을 이룰 수 있는 효과가 있다.As described in detail above, the control method of the present invention satisfactorily satisfies the cooling state of the refrigerating compartment by performing cooling by determining the operation or blocking of the compressor and the freezer fan according to the temperature detected from the refrigerating sensor of the refrigerating compartment. Compensation is made by raising or lowering the refrigeration reference temperature to achieve rapid load response.
