이하에서는 첨부도면을 참조하여 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 온도제어장치를 갖는 냉장고의 개략적 측단면도이다. 냉장고는 상부에 형성된 냉동실(1)과 하부에 형성된 냉장실(3)을 가지고 있다. 냉장고의 후면 하부에는 압축기(4)가 설치되어 있고, 냉장고의 후면에는 압축기(4)로부터 압축된 냉매에 의해 냉기를 생성하는 증발기(5)가 설치되어 있다. 증발기(5)의 상부에는 송풍팬(6)이 설치되어 증발기(5)로부터의 냉기를 냉동실(1) 및 냉장실(3)로 송풍한다. 이 송풍된 냉기에 의해 냉동실(1) 및 냉장실(3)의 냉각작동이 이루어진다.1 is a schematic side cross-sectional view of a refrigerator having a temperature control device according to the present invention. The refrigerator has a freezing chamber (1) formed at the upper part and a refrigerating chamber (3) formed at the lower part. A compressor (4) is installed at the rear lower portion of the refrigerator, and an evaporator (5) for generating cold air by the refrigerant compressed by the compressor (4) is provided at the rear surface of the refrigerator. A blowing fan 6 is provided at an upper part of the evaporator 5 to blow cool air from the evaporator 5 to the freezing chamber 1 and the refrigerating chamber 3. [ The cooling operation of the freezing chamber (1) and the refrigerating chamber (3) is performed by the blown cold air.
증발기(5)에 인접한 영역에는 제상히터(9)가 설치되어 있다. 제상히터(9)는 냉장고의 냉각작동이 수행되지 않는 휴지기동안 가열작동하여, 냉각작동에 중에 증발기(5)의 외표면에 생성되는 성애를 제거하는 역할을 한다.A defrost heater (9) is provided in a region adjacent to the evaporator (5). The defrost heater 9 performs a heating operation during a rest period during which the cooling operation of the refrigerator is not performed, thereby eliminating the malaise generated on the outer surface of the evaporator 5 during the cooling operation.
냉동실(1) 내에는 냉동실(1) 냉부의 온도을 측정하는 냉동실온도센서(14)가 설치되어 있고, 냉장실(3) 내에는 냉장실(3) 내부의 온도를 측정하는 냉장실온도센서(13)가 설치되어 있다. 또한, 냉장고의 상면 후단부에는 냉장고 주변의 외기온도를 측정하는 외기온도센서(11)가 설치되어 있다.A freezer compartment temperature sensor 14 for measuring the temperature of the cold section of the freezing compartment 1 is provided in the freezing compartment 1 and a refrigerating compartment temperature sensor 13 for measuring the temperature inside the refrigerating compartment 3 is installed in the refrigerating compartment 3 . An outside temperature sensor 11 for measuring the outside temperature around the refrigerator is provided at the rear end of the top surface of the refrigerator.
도 2는 본 발명에 따른 온도제어장치의 제어블럭도이다. 냉장고의 냉각작동 및 냉장실(3) 온도제어는 마이컴(20)에 의해 수행된다. 마이컴(20)의 입력측에는 냉장실온도센서(13)와 냉동실온도센서(14) 및 외기온도센서(11)가 연결되어, 각각 냉장실(3) 및 냉동실(1)의 내부온도와 외기온도의 측정치를 마이컴(20)에 입력한다. 마이컴(20)의 출력측에는 송풍팬(6)과 제상히터(9) 및 압축기(4)가 연결되어 있다.2 is a control block diagram of the temperature control device according to the present invention. The cooling operation of the refrigerator and the temperature control of the refrigerating chamber (3) are performed by the microcomputer (20). The freezing compartment temperature sensor 13, the freezing compartment temperature sensor 14 and the outside air temperature sensor 11 are connected to the input side of the microcomputer 20 to measure the internal temperature and the outside air temperature of the refrigerating compartment 3 and the freezing compartment 1, And inputs it to the microcomputer 20. A blowing fan 6, a defrost heater 9, and a compressor 4 are connected to the output side of the microcomputer 20.
사용자는 냉장고의 외면에 형성된 조작판넬(도시하지 않음)을 조작하여 냉동실(1) 및 냉장실(3)의 원하는 냉각강도를 설정한다. 마이컴(20)은 냉동실(1) 및 냉장실(3)이 설정된 냉각강도에 해당하는 냉각온도를 유지하도록 압축기(4) 및 송풍팬(6)의 구동을 제어한다.The user operates the operation panel (not shown) formed on the outer surface of the refrigerator to set the desired cooling strength of the freezing chamber 1 and the refrigerating chamber 3. [ The microcomputer 20 controls the driving of the compressor 4 and the blowing fan 6 so that the freezing chamber 1 and the refrigerating chamber 3 maintain the cooling temperature corresponding to the set cooling strength.
외기온도센서(11)에서 측정된 외기온도가 설정된 냉장실(3) 냉각강도에 해당하는 냉각온도보다 높을 경우에는, 마이컴(20)은 정상적인 냉장고의 냉각작동을 수행한다. 즉, 마이컴(20)은 냉동실온도센서(14)로부터의 온도측정치를 기준으로 냉동실(1)의 온도를 측정하여 냉각작동을 수행할 필요가 있는 것으로 판단된 경우, 압축기(4)의 구동을 개시하여 증발기(5)로부터 냉기를 생성하고 송풍팬(6)을 구동하여 냉동실(1) 및 냉장실(3)에 냉기를 공급하는 냉각작동을 수행한다.When the outside air temperature measured by the outside temperature sensor 11 is higher than the cooling temperature corresponding to the set cooling intensity of the refrigerating chamber 3, the microcomputer 20 performs normal cooling operation of the refrigerator. That is, when the microcomputer 20 determines that it is necessary to perform the cooling operation by measuring the temperature of the freezing chamber 1 based on the temperature measurement value from the freezing room temperature sensor 14, the microcomputer 20 starts driving the compressor 4 So that cooling air is generated from the evaporator 5 and the blowing fan 6 is driven to perform a cooling operation for supplying cold air to the freezing chamber 1 and the refrigerating chamber 3. [
외기온도가 낮을 경우, 즉, 외기온도센서(11)에서 측정된 외기온도가 냉장실(3) 냉각강도에 해당하는 냉각온도보다 낮을 경우에는 마이컴(20)은 냉각작동을 수행하지 않고, 본 발명에 따른 온도제어방법을 수행한다.When the outside air temperature is low, that is, when the outside air temperature measured by the outside air temperature sensor 11 is lower than the cooling temperature corresponding to the cooling strength of the refrigerating chamber 3, the microcomputer 20 does not perform the cooling operation, The temperature control method according to the present invention.
도 3은 본 발명에 따른 온도제어방법의 흐름도이다.3 is a flow chart of the temperature control method according to the present invention.
마이컴(20)은 상시 외기온도와 냉장실(3) 내부온도를 측정하여(S1), 사용자가 설정한 냉장실(3) 냉각강도에 해당하는 냉각온도와 이 내부온도를 비교한다(S2). 냉장실(3) 내부온도가 냉각온도보다 낮을 경우에는, 마이컴(20)은 이 낮은 상태가 지속되는 시간을 적산하고(S3), 적산된 시간이 6시간에 이르면(S4) 제상히터(9)를 ON시켜(S5) 제상히터(9)로부터의 열로 냉장실(3) 내부를 가열하여 과냉을 방지한다. 이때의 6시간은 낮은 외기온도에 의해 냉장실(3) 내부가 과냉될 수 있는 시간으로서, 냉장고의 종류에 따라 다르게 정해질 수 있다. 이 적산시간에 의해 불필요한 잦은 제상히터(9) 작동을 방지할 수 있고, 실질적인 과냉이 발생하는 경우에만 제상히터(9)를 작동시킬 수 있게 된다.The microcomputer 20 measures the outside temperature and the internal temperature of the refrigerating chamber 3 at step S1 and compares the internal temperature with the cooling temperature corresponding to the cooling strength of the refrigerating chamber 3 set by the user at step S2. When the internal temperature of the refrigerating chamber 3 is lower than the cooling temperature, the microcomputer 20 accumulates the time for which the low state is maintained (S3). When the accumulated time reaches 6 hours (S4), the defrost heater 9 (S5) and the inside of the refrigerating chamber (3) is heated by the heat from the defrost heater (9) to prevent overcooling. At this time, the time for the inside of the refrigerating chamber (3) to be sub-cooled by the low outside temperature may be determined depending on the type of the refrigerator. By this integration time, unnecessary frequent operation of the defrost heater 9 can be prevented, and the defrost heater 9 can be operated only when substantial overcooling occurs.
제상히터(9)가 가열작동을 하는 동안, 마이컴(20)은 냉장실(3) 내부온도를 냉각온도와 비교하는 작동을 수행하여(S6), 냉장실(3) 내부온도가 더 높을 경우에는 과냉이 방지된 것으로 보고 제상히터(9)를 OFF시킨다(S7). 냉장실(3) 내부온도가 더 낮을 경우에는 과냉이 방지되지 않은 것으로 보고, 제상히터(9)의 작동시간을 적산시키며(S8), 제상히터(9) 작동시간의 적산 및 온도 비교를 반복하여 이 적산된 시간이 30분 이상에 이르게 되면(S9), 송풍팬(6)을 작동시킨다(S10). 즉, 30분 이상 제상히터(9)를 작동시켜도 과냉이 방지되지 않고 있으므로, 송풍팬(6)에 의해 제상히터(9)의 열을 냉장실(3) 내에 직접적으로 공급하여 냉장실(3)의 과냉방지 효과를 높이는 것이다.The microcomputer 20 performs the operation of comparing the internal temperature of the refrigerating chamber 3 with the cooling temperature during the heating operation of the defrost heater 9 at step S6 and if the internal temperature of the refrigerating chamber 3 is higher, And the defrost heater 9 is turned off (S7). The operation time of the defrost heater 9 is accumulated (S8), and the integration of the operation time of the defrost heater 9 and the temperature comparison are repeated, When the accumulated time reaches 30 minutes or more (S9), the blowing fan 6 is operated (S10). That is, even if the defrost heater 9 is operated for 30 minutes or more, the overheating is not prevented. Therefore, the heat of the defrost heater 9 is directly supplied to the defrosting chamber 3 by the blowing fan 6, Prevention effect.
제상히터(9)와 송풍팬(6)이 작동되는 동안에도 지속적으로 냉장실 내부온도와 설정된 냉각온도를 비교하여(S11), 냉장실(3) 내부온도가 설정된 냉각온도보다 높게 되면 송풍팬(6)과 제상히터(9)를 OFF시켜(S12) 냉장실(3) 내부의 가열작동을 마친다. 이에 따라, 냉장실(3)의 과냉이 방지된다.The temperature of the interior of the refrigerating compartment is continuously compared with the set cooling temperature even during the operation of the defrost heater 9 and the blowing fan 6 in step S11 and if the internal temperature of the refrigerating compartment 3 becomes higher than the set cooling temperature, And the defrost heater 9 are turned off (S12), and the heating operation inside the refrigerating chamber 3 is completed. Thereby, overcooling of the refrigerating chamber (3) is prevented.
본 실시예에서는 한 개의 증발기(5)와 한 개의 송풍팬(6)을 사용한 냉장고에 본 발명에 따른 온도제어장치 및 온도제어방법을 적용하여 설명하였으나, 증발기 및 송풍팬이 냉동실(1) 및 냉장실(3)에 각각 설치되어 각각 냉각작동을 수행하는 냉장고에서도 적용할 수가 있다. 이 경우에도, 전술한 바와 같이 냉장고의 냉각작동은 통상적으로 냉동실의 온도 측정치에 기준하여 수행되고, 냉장실의 온도제어는 냉장실용 증발기와 냉장실용 송풍팬을 사용하여 본 발명에 따른 냉장실 온도제어방법 및 온도제어장치가 구성된다.In the present embodiment, the temperature control device and the temperature control method according to the present invention are applied to a refrigerator using one evaporator 5 and one blower fan 6. However, the evaporator and the blower fan may be provided in the freezer compartment 1 and the refrigerating compartment The present invention can also be applied to a refrigerator which is respectively installed in the refrigerator 3 and performs a cooling operation. Also in this case, the cooling operation of the refrigerator is performed based on the temperature measurement value of the freezing room as described above, and the temperature control of the refrigerating chamber is performed by using the refrigerator room evaporator and the refrigerator room blowing fan, A temperature control device is constituted.
이상 설명한 바와 같이, 본 발명에 따르면, 외기의 온도가 지나치게 낮은 경우에도 냉장고 내의 냉장실의 과냉이 발생하지 않게 된다.As described above, according to the present invention, even if the temperature of the outside air is excessively low, supercooling of the refrigerating chamber in the refrigerator is prevented.
