Same as

도2는 종래 냉장고 냉동사이클 장치를 개략적으로 도시한 구성도이고, 도3은 종래 냉장고 냉동사이클 장치의 P-H선도로서, 이에 도시된 바와 같이 압축기(10)는 저온, 저압의 냉매증기를 증발기(10)에서 흡입하여 압축을 하고 고온, 고압의 증기로 응축기로 보내면 상기 응축기(11)에서 고압의 포화액으로 변화시키고, 이 고압 냉매액은 좁게 설계된 관의 저항에 의해 고압의 냉매 압력은 내려가며, 압력이 내려가면 온도 또한 내려가는 현상에 의해 저온, 저압의 냉매로 바뀌어 다시 상기 증발기(10)로 들어간다.2 is a schematic view showing a conventional refrigerator refrigeration cycle apparatus, Figure 3 is a PH diagram of a conventional refrigerator refrigeration cycle apparatus, as shown in the compressor 10 is a low-temperature, low pressure refrigerant vapor evaporator (10) Inhaled by the compressed air and sent to the condenser with high temperature and high pressure steam, the condenser 11 changes to a saturated high pressure liquid, and the high pressure refrigerant liquid is lowered by the resistance of the narrowly designed pipe. When the pressure decreases, the temperature is also changed to a low temperature, low pressure refrigerant due to the phenomenon that the temperature is lowered to enter the evaporator 10 again.

상기 증발기(10)로 들어온 저온, 저압의 냉매는 주변의 온도보다 온도가 낮으므로, 주위의 열을 흡수하여 활발히 증발하여 상기 증발기(10)의 출구에서는 액분이 없는 포화증기로 되어 흡입관을 통해 상기 압축기(10)로 흡입되어 다시 고온, 고압의 증기로 압축된다.Since the low temperature and low pressure refrigerant entering the evaporator 10 has a lower temperature than the ambient temperature, the refrigerant absorbs the surrounding heat and actively evaporates, so that the vapor of the evaporator 10 is saturated steam without liquid content and is discharged through the suction pipe. It is sucked into the compressor 10 and is compressed again into high temperature and high pressure steam.

도4는 종래 냉장고 냉동제어장치의 동작 흐름도로서, 이에 도시된 바와 같이 온도감지부(14)에서 냉장실과 냉동실의 온도를 감지하면 마이크로 컴퓨터(15)에서 감지된 온도가 설정온도 범위인가를 판단하여 설정범위에 있지 않으면 구동부(16)에 제어신호를 보내 압축기(11)와 냉동팬(13)을 구동시키며, 상기 압축기(11)의 구동 중에 상기 온도감지부(14)에서 감지된 온도가 설정온도 범위인가를 다시 상기 마이크로 컴퓨터(15)에서 판단하여 설정범위에 있지 않으면 상기 구동부(16)에 제어신호를 보내 상기 압축기(11)와 냉동팬(13)을 계속 구동시키고, 설정범위 내에 있으면 상기 압축기(11)와 냉동팬(13)의 구동을 정지시킨다.4 is an operation flowchart of a conventional refrigerator refrigeration control device. As shown in FIG. 4, when the temperature detecting unit 14 senses the temperature of the refrigerating compartment and the freezing compartment, it is determined whether the temperature detected by the microcomputer 15 is within a set temperature range. If it is not within the setting range, a control signal is sent to the driving unit 16 to drive the compressor 11 and the refrigeration fan 13, and the temperature detected by the temperature sensing unit 14 during the operation of the compressor 11 is the set temperature. If it is not within the setting range, the microcomputer 15 determines whether it is within the setting range and sends a control signal to the driving unit 16 to continuously drive the compressor 11 and the refrigeration fan 13, and if it is within the setting range, the compressor. (11) and the refrigeration fan 13 are stopped.

상기와 같이 종래의 방법에 있어서는 사용자가 냉장고의 문을 열었을 경우 외부온도와 냉동실 또는 냉장실 내부의 온도의 차이로 인하여 냉동실 또는 냉장실 내부의 온도가 상승하여 설정온도의 범위를 벗어나면 압축기를 구동하여 설정온도를 유지함으로써, 압축기의 구동시간 증가로 인하여 소비전력이 증가하고, 열 손실이 큰 문제점이 있었다.In the conventional method as described above, when the user opens the door of the refrigerator, the temperature inside the freezer compartment or the refrigerating compartment increases due to the difference between the external temperature and the temperature inside the freezer compartment or the refrigerator compartment. By maintaining the temperature, the power consumption increases due to the increase in the operating time of the compressor, there was a problem that the heat loss is large.

따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 창안한 것으로, 사용자가 냉장고의 문을 열었을 때에 냉장고 내의 온도를 고려하지 않고 무조건 압축기를 일정시간 구동시켜 외부의 열에 의한 냉장고 내부온도의 상승을 방지하는 제어방법을 제공함에 목적이 있다.Therefore, the present invention was devised to solve the above-mentioned conventional problems, and when the user opens the door of the refrigerator, the compressor internally drives the compressor for a certain time without considering the temperature in the refrigerator, thereby raising the internal temperature of the refrigerator due to external heat. It is an object to provide a control method for preventing.

이하, 본 발명에 따른 실시 예를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도5는 본 발명 냉장고 냉동제어방법의 동작 흐름도로서, 이에 도시한 바와 같이 냉장고의 냉동제어방법은 두 가지의 방법으로 나뉘어 지는데 첫 번째 제어방법은 냉장고의 문이 열려있는가를 판단하여 냉장고 문이 닫혀있으면 온도감지부(14)에서 냉장실과 냉동실의 온도를 감지하고, 마이크로 컴퓨터(15)에서 상기 감지된 온도가 설정온도 범위인가를 판단하여 설정범위에 있지 않으면 구동부(16)에 제어신호를 보내 압축기(11)와 냉동팬(13)을 구동시키며, 상기 압축기(11)와 냉동팬(13)의 구동 중에 상기 온도감지부(14)에서 감지된 온도가 설정온도 범위인가를 다시 상기 마이크로 컴퓨터(15)에서 판단하여 설정범위에 있지 않으면 상기 구동부(16)에 제어신호를 보내 상기 압축기(11)와 냉동팬(13)을 계속 구동시키고, 설정범위 내에 있으면 상기 압축기(11)와 냉동팬(13)의 구동을 정지시키고 동작을 끝낸다.5 is an operation flowchart of the refrigerator refrigeration control method according to the present invention. As shown in the drawing, the refrigeration control method of the refrigerator is divided into two methods. The first control method is to determine whether the door of the refrigerator is open. The temperature detecting unit 14 detects the temperatures of the refrigerating compartment and the freezing compartment, and determines whether the detected temperature is within the set temperature range by the microcomputer 15 and sends a control signal to the driving unit 16 if it is not within the set range. 11) and the refrigeration fan 13, and the microcomputer 15 again checks whether the temperature detected by the temperature sensing unit 14 during the operation of the compressor 11 and the refrigeration fan 13 is within a set temperature range. If it is determined not in the set range, and sends a control signal to the drive unit 16 continues to drive the compressor 11 and the refrigeration fan 13, and if within the set range and the compressor 11 and Stop the driving of dongpaen 13 and ends the operation.

두 번째 제어방법은 냉장고의 문이 열려있는가를 판단하여 냉장고 문이 열려 있으면 압축기(11)를 구동시키고, 일정시간이 경과하였는가를 판단하여 상기 압축기(11)의 구동시간이 일정시간 경과하였으면 상기 압축기(11)의 구동을 멈추고 동작을 끝낸다.The second control method is to determine whether the door of the refrigerator is open to drive the compressor (11) if the refrigerator door is open, and to determine whether the predetermined time has elapsed, if the drive time of the compressor (11) has elapsed a predetermined time (the compressor ( 11) Stop driving and finish the operation.

상기 미리 설정된 압축기(11)의 구동시간이 도어 열림 경보시간보다 크면 냉장고 문이 닫혔어도 계속 구동함으로, 도어 열림 경보시간보다 작은 범위 이내로 하여 소비전력량과 열손실량을 최소화 한다.If the preset driving time of the compressor 11 is greater than the door opening alarm time, the refrigerator door continues to be driven even if the refrigerator door is closed, thereby minimizing the power consumption and heat loss amount within a range smaller than the door opening alarm time.

이상에서 설명한 바와 같이 본 발명 냉장고 냉동제어방법은 사용자가 냉장고의 문을 열었을 때에 냉장고 내의 온도를 고려하지 않고 무조건 압축기를 일정시간 구동시켜 외부의 열에 의한 냉장고 내부온도의 상승을 방지함으로써, 소비전력량 및 열손실을 최소화하는 효과가 있다.As described above, the refrigerator refrigeration control method of the present invention does not consider the temperature in the refrigerator when the user opens the door of the refrigerator, and unconditionally drives the compressor for a predetermined time, thereby preventing an increase in the internal temperature of the refrigerator due to external heat, thereby reducing power consumption and It has the effect of minimizing heat loss.
