Description

냉장고의 고내온도 제어방법How to control the high temperature inside the refrigerator

본 발명은 냉장고의 고내온도 제어방법에 관한 것으로, 특히 외기온도가 일정온도보다 낮을 경우, 압축기가 오프되는 구간에서 냉장실 전용의 제상히터를 구동시켜 냉장실의 고내온도를 기준온도까지 상승시킴으로써, 냉장실의 온도를 정상적인 온도로 유지시킬 수 있는 냉장고의 고내온도 제어방법에 관한 것이다.The present invention relates to a method for controlling the internal temperature of a refrigerator. In particular, when the outside air temperature is lower than a predetermined temperature, the defrost heater for the refrigerating compartment is driven in a section in which the compressor is turned off, thereby raising the internal temperature of the refrigerating compartment to a reference temperature. The present invention relates to a method for controlling the internal temperature of a refrigerator capable of maintaining a temperature at a normal temperature.

일반적으로 냉장고는 단일의 증발기와 송풍팬을 구비하여 냉동실과 냉장실에 공통으로 냉기를 공급하여 고내를 냉각시키는 방식과, 복수의 증발기와 송풍팬을 구비하여 냉동실과 냉장실에 별도로 냉기를 공급함으로써 복수의 고내을 각각 독립적으로 냉각시키는 방식이 있다.In general, a refrigerator includes a single evaporator and a blower fan to supply cold air to the freezer compartment and the refrigerating compartment in common to cool the inside of the refrigerator, and a plurality of evaporators and blower fans to supply the cold air to the freezer compartment and the refrigerator compartment separately. There is a method of cooling each inside of the refrigerator independently.

독립냉각방식을 위한 종래의 냉장고(10)는 도 1에 도시된 바와 같이, 냉장고 본체(11)와, 그 본체(11)내부에 상호간의 냉기혼합이 일어나지 않도록 구획된 하측의 냉동실(12)과 상측의 냉장실(13)이 형성된다. 상기 냉동실(12) 및 냉장실(13)은 중간격벽(14)에 의하여 구획되고, 각각의 도어(15),(16)에 의하여 개폐된다. 또한, 상기 냉장실(13)의 후벽에는 제1냉각기(17)와 냉장실팬(18)이 설치되고, 냉동실(12)의 후벽에는 제2냉각기(19)와 냉동실팬(20)이 설치된다. 그리고, 냉장고 본체(11)의 하측에는 압축기(21)가 설치된다.As shown in FIG. 1, the conventional refrigerator 10 for the independent cooling method includes a refrigerator main body 11 and a lower freezing chamber 12 partitioned so that cold air mixing does not occur within the main body 11. An upper refrigerating chamber 13 is formed. The freezing chamber 12 and the refrigerating chamber 13 are partitioned by the intermediate partition 14 and are opened and closed by respective doors 15 and 16. In addition, a first cooler 17 and a refrigerating chamber fan 18 are installed on the rear wall of the refrigerating chamber 13, and a second cooler 19 and a freezing chamber fan 20 are installed on the rear wall of the freezing chamber 12. The compressor 21 is installed below the refrigerator main body 11.

이와 같이 구성되는 종래의 독립냉각방식의 냉장고에 있어서, 냉동실(12)의 온도는 도 2a와 같이 제어된다. 즉, 냉동실(12)의 온도가 기준온도보다 높아지면 도 2b 및 도 2c와 같이 압축기(21) 및 냉동실팬(20)이 턴온되어 냉동실(12)의 온도를 낮추게 된다. 또한, 냉동실(12)의 온도가 기준온도보다 낮아지면 도 2b 및 도 2c와 같이 압축기(21) 및 냉동실팬(20)이 턴오되어, 냉동실(12)의 온도가 더이상 낮아지지 않도록 한다.In the conventional independent cooling type refrigerator configured as described above, the temperature of the freezing chamber 12 is controlled as shown in FIG. 2A. That is, when the temperature of the freezer compartment 12 is higher than the reference temperature, the compressor 21 and the freezer compartment fan 20 are turned on as shown in FIGS. 2B and 2C to lower the temperature of the freezer compartment 12. In addition, when the temperature of the freezer compartment 12 is lower than the reference temperature, the compressor 21 and the freezer compartment fan 20 are turned on as shown in FIGS. 2B and 2C, so that the temperature of the freezer compartment 12 is no longer lowered.

그런데, 상기와 같은 독립냉각방식의 냉장고에 있어서, 냉장고 주변의 외기온도가 낮으면 냉동실(12) 및 냉장실(13)을 구분하는 중간격벽(14)의 두꼐 및 넓이에 따라 냉동실(12)이 냉장고 밖으로부터 받아들이는 열량보다 냉동실(12)로 빼앗기는 열량이 더 많게 된다.By the way, in the independent cooling method as described above, when the outside air temperature around the refrigerator is low, the freezer compartment 12 is a refrigerator according to the thickness and width of the intermediate partition 14 separating the freezer compartment 12 and the refrigerating compartment 13. More calories are taken into the freezer compartment 12 than calories taken out from the outside.

이에 따라 냉장실(13)의 고내온도는 실제 제어하려는 온도보다 매우 낮은 고내온도를 유지한다. 또한, 도 3a와 같이 냉장실팬(18)을 계속하여 오프시켜도 도 3b와 같이 냉장실(13)의 온도는 기준온도보다 0°C ∼ 5°C까지 낮은 상태로 유지된다.Accordingly, the internal temperature of the refrigerating chamber 13 maintains a very low internal temperature than the temperature to be actually controlled. In addition, even when the refrigerator compartment fan 18 is continuously turned off as shown in FIG. 3A, the temperature of the refrigerator compartment 13 is maintained at 0 ° C. to 5 ° C. below the reference temperature as shown in FIG. 3B.

이와 같이 냉장고의 주변온도가 낮으면 냉장실(13)의 고내는 과냉상태가 되어, 수납된 식품이 손상되는 문제가 발생된다.As such, when the ambient temperature of the refrigerator is low, the interior of the refrigerator compartment 13 becomes a supercooled state, which causes a problem that the stored food is damaged.

상기와 같은 냉장실(13)의 과냉현상을 방지하기 위하여 냉동실(12) 및 냉장실(13)을 구분하는 중간격벽(14)을 두껍게하면 냉동실(12)과 냉장실(13)의 실제 내용적이 줄어들어 냉장고 효율이 떨어지게 된다. 또한, 냉장실(13)의 기준온도를 낮추더라도 상기와 같은 과냉현상이 발생되는 것을 방지할 수 없다.In order to prevent the overcooling of the refrigerating compartment 13 as described above, thickening the intermediate partition 14 separating the freezer compartment 12 and the refrigerating compartment 13 reduces the actual contents of the freezer compartment 12 and the refrigerating compartment 13, thereby reducing the efficiency of the refrigerator. Will fall. In addition, even if the reference temperature of the refrigerating chamber 13 is lowered, it is not possible to prevent the occurrence of such subcooling.

상기와 같은 종래의 문제점을 해결하기 위하여, 본 발명은 외기온도가 일정온도보다 낮을 경우, 압축기가 오프되는 구간에서 냉장실 전용의 제상히터를 구동시켜 냉장실의 고내온도를 기준온도까지 상승시킴으로써, 냉장실의 온도를 정상적인 온도로 유지시킬 수 있는 냉장고의 고내온도 제어방법을 제공함을 목적으로 한다.In order to solve the above problems, the present invention, when the outside temperature is lower than the predetermined temperature, by driving the defrost heater dedicated to the refrigerator compartment in the section of the compressor off by raising the internal temperature of the refrigerator compartment to the reference temperature, An object of the present invention is to provide a method for controlling the internal temperature of a refrigerator capable of maintaining a temperature at a normal temperature.

상기 목적을 달성하기 위한 본 발명은 압축기가 구동될 때, 냉장실의 고내온도를 감지하여 감지된 고내온도에 따라 냉장실팬을 구동시켜 냉장실을 냉각시키는 냉각단계와; 압축기가 구동되지 않을 때, 외기온도센서에 의하여 감지된 냉장고 외부의 온도가 기설정된 일정온도보다 낮은가를 판단하는 외기온도판단단계와; 그 외기온도판단단계에서의 판단결과에 따라, 냉장실팬 및 냉장실제상히터를 구동시켜 냉장실의 온도를 냉장실의 상한온도까지 높이는 열공급단계와; 냉장실의 온도가 냉장실의 상한온도에 이르면, 냉장실팬 및 냉장실제상히터를 구동중단시키는 높열공급중단단계;로 구성됨을 특징으로 한다.The present invention for achieving the above object is a cooling step of cooling the refrigerating compartment by driving the refrigerating chamber fan in accordance with the sensed high internal temperature by detecting the internal temperature of the refrigerator compartment when the compressor is driven; An outside temperature determining step of determining whether a temperature outside the refrigerator sensed by the outside temperature sensor is lower than a predetermined constant temperature when the compressor is not driven; A heat supply step of raising the temperature of the refrigerating compartment to the upper limit temperature of the refrigerating compartment by driving the refrigerating compartment fan and the refrigerating compartment defrost heater according to the determination result at the outside temperature determination step; When the temperature of the refrigerating chamber reaches the upper limit temperature of the refrigerating chamber, the high-heat supply interruption step of stopping the operation of the refrigerator compartment fan and the refrigerator compartment defrost heater; characterized in that consisting of.

냉장고 외부온도가 일정온도(T1) 이하일 경우, 단계(S18)에서 제어부(30)는 냉장실센서(32)에 의하여 감지된 냉장실온도가 냉장실온도의 하한온도(T2) 이하인가를 판단하고, 단계(S19)에서 도 6b 및 도 6c와 같이 냉장실팬(35) 및 냉장실용 제상히터(38)를 구동시킨다.When the external temperature of the refrigerator is less than or equal to the predetermined temperature T1, in step S18, the controller 30 determines whether the refrigerator compartment temperature detected by the refrigerator compartment sensor 32 is lower than or equal to the lower limit temperature T2 of the refrigerator compartment temperature, and performs the step ( In S19), the refrigerating chamber fan 35 and the refrigerating chamber defrost heater 38 are driven as shown in FIGS. 6B and 6C.

이에 따라, 냉장실의 온도는 점차 상승하게 된다.As a result, the temperature of the refrigerating chamber gradually increases.

단계(S20)에서 제어부(30)는 냉장실온도가 상한온도(T3)까지 상승되었는가를 판단하고, 단계(S21)에서 제어부(30)는 냉장실온도가 상한온도(T3)보다 낮으면 냉장실의 온도를 기준온도(T4)와 비교한다.In step S20, the controller 30 determines whether the temperature of the refrigerator compartment has risen to the upper limit temperature T3. In step S21, the controller 30 determines the temperature of the refrigerator compartment if the refrigerator compartment temperature is lower than the upper limit temperature T3. Compare with reference temperature (T4).

냉장실의 온도가 기준온도(T4) 이상이면, 단계(S22)에서 냉장실팬(36)은 계속 구동되고 냉장실 제상히터(37)는 구동중단된다.If the temperature of the refrigerating compartment is equal to or higher than the reference temperature T4, the refrigerating compartment fan 36 continues to be driven and the refrigerating compartment defrost heater 37 is stopped in step S22.

한편, 상기 단계(S20)에서의 판단결과, 상한온도(T3)까지 상승되었으면 열공급중단단계(S23)가 수행된다.On the other hand, as a result of the determination in step S20, if the temperature rises to the upper limit temperature (T3), the heat supply stop step (S23) is performed.

또한, 상기 단계(S21)에서의 판단결과, 냉장실의 온도가 기준온도(T4)보다 낮으면 열공급단계(S17-S22)의 처음으로 리턴되어 냉장실팬(36) 및 냉장실 제상히터(38)이 계속하여 구동되도록 한다.In addition, as a result of the determination in step S21, if the temperature of the refrigerating compartment is lower than the reference temperature T4, it is returned to the beginning of the heat supply step S17-S22 so that the refrigerating compartment fan 36 and the refrigerating compartment defrost heater 38 continue. To be driven.

이에 따라, 냉장실의 온도는 도 6d와 같이 종래보다 높게 제어되어 냉장실의 과냉을 방지할 수 있다.Accordingly, the temperature of the refrigerating compartment is controlled higher than in the prior art as shown in FIG.

상기와 같이 본 발명은 외기온도가 일정온도보다 낮을 경우, 압축기(34)가 오프되는 구간에서 냉장실 전용의 제상히터(38)를 구동시켜 냉장실의 고내온도를 기준온도까지 상승시킴으로써, 냉장실의 온도를 정상적인 온도로 유지시키고 냉장실의 과냉을 방지할 수 있다.As described above, in the present invention, when the outside temperature is lower than the predetermined temperature, the defrost heater 38 dedicated to the refrigerating compartment is driven in the section in which the compressor 34 is turned off, thereby raising the internal temperature of the refrigerating compartment to the reference temperature, thereby increasing the temperature of the refrigerating compartment. Maintain normal temperature and prevent the refrigerating chamber from overcooling.
