본 발명은 전자식 냉장고에 관한 것으로서, 더욱 상세하게는 댐퍼로 냉장실의 온도를 제어하도록 된 냉장고에 있어서 냉장실 도어의 개폐나 저장식품의 추가 등에 의한 냉장실 고내온도가 상승할 때 온도상승 정도에 따라 가장 빠른 시간 안에 냉장실 온도를 정상 설정 온도로 강하시키도록 된 냉장실 온도제어방법에 관한 것이다.The present invention relates to an electronic refrigerator, and more particularly, in a refrigerator configured to control a temperature of a refrigerating compartment with a damper, when the temperature in the refrigerating compartment high rises due to the opening and closing of a refrigerating compartment door or the addition of a stored food, the fastest temperature increases. It relates to a refrigerating compartment temperature control method for reducing the refrigerating compartment temperature to a normal set temperature in time.
종래의 기계식 또는 전자식 댐퍼를 사용하는 전자식 냉장고의 온도 제어방법은 냉장실의 온도를 기준으로 하여 압축기와 팬모우터를 단속제어하고, 냉장실의 온도는 단지 냉장실로 유입되는 냉기량을 댐퍼의 개폐각도를 조절하여 제어하게 되어 있기 때문에 냉장실의 고내온도가 높아져도 압축기나 팬모우터가 동작하지 않을 때에는 댐퍼를 최대로 열어 놓아도 고내 온도 강하가 신속하게 이루어지지 않게 된다.In the conventional method of controlling the temperature of an electronic refrigerator using a mechanical or electronic damper, the compressor and the fan motor are intermittently controlled based on the temperature of the refrigerating compartment, and the temperature of the refrigerating compartment merely determines the opening / closing angle of the damper. Since the temperature in the refrigerator compartment is high, even if the compressor or fan motor is not operating, even if the damper is opened to the maximum, the temperature drop in the refrigerator does not occur quickly.
따라서, 냉장실에 새로운 식품을 넣거나 또는 냉장실 도어를 오랫동안 열어 놓았다가 닫을 경우 냉장실의 온도는 상승하게 되고, 그 이후 냉장실의 온도가 정상 설정 온도까지 내력가기 까지는 많은 시간이 소요되기 때문에 저장식품의 신선도가 떨어지고 보관 가능 기간이 짧아지게 되는 단점이 있었다.Therefore, when a new food is put in the refrigerating compartment or when the refrigerating compartment door is opened and closed for a long time, the temperature of the refrigerating compartment increases. There was a disadvantage of falling and the storage period becomes shorter.
본 발명의 이와 같은 단점을 해결하기 위한 것으로, 냉장실의 고냉 온도가 상승하게 되면 온도 상승 정도에 따라 고내 온도를 가장 빠른 시간애에 적정온도로 낮혀줌으로서 항상 최적의 냉장 온도를 유지하도록 한 냉장고의 냉장실 온도제어 방법을 제공하는 것을 그 목적으로 한다.In order to solve the above disadvantages of the present invention, when the high temperature of the refrigerating chamber rises, the refrigerator keeps the optimal refrigerating temperature at all times by lowering the internal temperature to an appropriate temperature at the fastest time according to the degree of temperature rise. It is an object of the present invention to provide a refrigerating chamber temperature control method.
이와 같은 목적을 달성하기 위하여, 본 발명의 냉장실 온도 제어방법은 냉동실 온도에 따라 압축기 및 팬모우터를 단속 제어하고 냉장실 온도에 따라 댐퍼를 개폐제어하는 냉장고의 냉동·냉장실 온도 제어방법에 있어서, 냉장실의 고내 온도 상승여부를 검출하여 제1설정온도 이하로 고내온도가 상승했을 경우 팬모우터만을 연속 가동시키고, 제1설정온도 이상으로 고내온도가 상승했을 경우에는 압축기 및 팬모우터를 동시에 연속 가동시키며, 이와 같은 상태에서 고내온도가 제2설정 온도가지 하강하면 정상적인 냉동·냉장실 온도제어가 이루어지도록 하는 것을 특징으로 한다.In order to achieve the above object, the refrigerating compartment temperature control method of the present invention is a refrigerator and refrigerating compartment temperature control method of the refrigerator for intermittently controlling the compressor and the fan motor according to the freezer compartment temperature and opening and closing the damper according to the refrigerator compartment temperature. If the internal temperature rises below the first set temperature, the fan motor is continuously operated. If the internal temperature rises above the first set temperature, the compressor and the fan motor operate continuously. In this state, when the high temperature inside the second set temperature falls, it is characterized in that the normal control of the freezer and refrigerator compartment temperature.
이하, 본 발명의 방법의 구체적인 특징 및 작용효과를 첨부도면에 의해 상세히 설명한다.Hereinafter, specific features and effects of the method of the present invention will be described in detail by the accompanying drawings.
일반적인 냉장고의 온도 제어방법은, 제1도에서와 같이, 냉장실 도어가 개방 되면 팬모우터가 정지되고(A구간), 이때 냉장실 내의 냉기의 유실 및 새로운 식품의 추가에 의해 냉장실의 고냉온도가 상승되는데, 이후 냉장실 도어가 닻히면 냉동실의 온도에 따라 압축기 및 팬모우터가 단속 제어됨으로써 냉장실 온도가 점차로 하강되어 정상적인 냉장온도(약 +2℃)떨어지게 된다(E1 곡선).In a typical refrigerator temperature control method, as shown in FIG. 1, when the refrigerator compartment door is opened, the fan motor is stopped (section A), and the high temperature of the refrigerator compartment is increased by the loss of cold air in the refrigerator compartment and the addition of new food. After the refrigerator door is anchored, the compressor and the fan motor are intermittently controlled according to the temperature of the freezer compartment so that the temperature of the refrigerator compartment is gradually lowered to drop the normal refrigerator temperature (about + 2 ° C.).
한편, 실온이 높거나 새로운 식품이 많이 추가될 경우 냉장실의 온도는 더욱 높게 상승되며, 정상 냉장온도로 떨어지기 까지는 더욱 많은 시간임 소요된다(E2곡선).On the other hand, when the room temperature is high or when a lot of new food is added, the temperature of the refrigerating chamber rises even higher, and it takes more time to fall to the normal refrigerating temperature (E 2 curve).
따라서, 냉장실의 고내온도가 이상상태로 유지되는 시간(B구간)이 길어지게 되므로 냉장식품의 신선도가 떨어지게 된다.Therefore, since the time (section B) during which the internal temperature of the refrigerating chamber is maintained in an abnormal state becomes long, the freshness of the refrigerated food is reduced.
본 발명에 의한 냉장실 온도 제어방법은, 제3도의 알고리즘과 같이 수행되는데, 냉장실 도어개폐나 새로운 식품추가에 의해 고내온도가 상승하게(101) 되면, 상기 고내온도가 제1설정온도 이상 상승했는가의 여부를 판단한다(102).The method of controlling the refrigerator compartment temperature according to the present invention is performed as shown in the algorithm of FIG. 3. It is determined (102).
즉, 실온이 높은 상태에서 냉장실 도어를 개폐하거나 많은 식품이 추가되어 감지된 고내온도가 제1설정온도, 예를 들어 +5℃이상으로 상승하게 되면, 압축기와 팬모우터를 동시에 연속가동시킴(106)과 함께 댐퍼를 개방하여(107) 제2도 (b)의 D2구간과 같이 고내온도를 더욱 빨리 강하시키게 되면, 이와 같은 상태에서 고내 온도가 제2설정온도까지 하강했는가를 판단하여(108), 제2설정온도, 예를 들어 0℃까지 하강하면(E4곡선), 다시 냉동실의 냉동온도에 따라 압축기와 팬모우터를 단속제어하는 일반적인 온도제어기능이 이루어지게(109) 되며, 제2설정온도까지 하강하지 않았으면 상기 루틴(106-108)을 반복 실행한다.That is, when the refrigerator compartment door is opened at a high temperature or a lot of food is added, and the detected internal temperature rises above the first set temperature, for example, + 5 ° C., the compressor and the fan motor are operated at the same time. When 106) and thereby together by opening the damper 107, FIG. 2 (b) of the D 2 period the internal temperature as the faster descent, the internal temperature in this state to judge did lowered to a second predetermined temperature ( 108), when the temperature falls to a second set temperature, for example, 0 ° C. (E 4 curve), a general temperature control function for intermittently controlling the compressor and the fan motor is performed (109) according to the freezing temperature of the freezer compartment. If the routine has not fallen to the second set temperature, the routines 106-108 are repeatedly executed.
한편, 고내온도가 제1설정온도, 예를 들어 +5℃이하로 상승하였을 경우에는 제2도 (a)에서와 같이 팬모우터를 연속가동시킴(103)과 함께 댐퍼를 개방시키며(104), 이와 같은 상태에서 고내온도가 제2설정온도까지 하강했는가를 판단하여(105), 고내온도가 제2설정온도, 예를 들어 0℃까지 하강하면(ES곡선)다시 냉동 실의 냉동온도에 따라 압축기와 팬모우터를 단속제어하는 일반적인 온도 제어기능이 이루어지게(109) 되며, 제2설정온도까지 하강하지 않았으며 상기 루틴(103-105)을 반복실행한다.On the other hand, when the internal temperature rises below the first set temperature, for example, + 5 ° C., the fan motor is continuously operated as shown in FIG. 2 (a) (103) and the damper is opened (104). In this state, it is determined whether the internal temperature has fallen to the second set temperature (105), and when the internal temperature drops to the second set temperature, for example, 0 ° C (E S curve), it is returned to the freezing temperature of the freezer compartment. Accordingly, a general temperature control function for intermittent control of the compressor and the fan motor is achieved (109), and the routines (103-105) are repeatedly executed without falling to the second set temperature.
따라서, 냉장실 도어 개방기간(A구간) 후에 상승된 냉장실의 고내온도가 정상 냉장온도로 떨어지기까지의 이상온도기간(B1구간)이 팬모우터의 동작(D1구간)이 짧아지게 되는데, 이때 전자식 댐퍼를 사용하는 냉장고의 경우 댐퍼는 개방상태로 되어 냉장실로 최대한의 냉기유입이 이루어지게 된다.Thus, the refrigerator compartment door opening period (A period) after the above temperature period of the internal temperature of an elevated cold room to fall to a normal refrigeration temperatures (B 1 section) The operation of the fan Motor (D 1 section) there is be a shorter, In this case, in the case of the refrigerator using the electronic damper, the damper is opened to maximize the cold air flow into the refrigerating chamber.
이로써 압축기와 팬모우터가 연속 가동되는 이상온도구간(B2구간)이 짧아지게 되는데, 이렇게 압축기가 동작되면 냉동실의 온도가 정상설정온도(-18℃)보다 3∼4℃정도 낮아질 수 있으나, 상기의 정상 냉동온도가 매우 낮은 온도이므로 단시간 동안 3∼4℃ 낮아지는 것은 냉동식품에 큰 영향을 미치지 않으므로 문제가 되지 않는다.As a result, the abnormal temperature section (B 2 section) in which the compressor and the fan motor are continuously operated is shortened. When the compressor is operated, the temperature of the freezer compartment may be lowered by 3 to 4 ° C from the normal set temperature (-18 ° C). Since the normal freezing temperature is a very low temperature, the lowering of 3 to 4 ° C. for a short time is not a problem since it does not have a great influence on the frozen food.
이때, 전자식 댐퍼를 사용하는 냉장고의 경우, 압축기 및 팬모우터의 연속 가동 기간중 댐퍼는 개방상태로 두게 된다.At this time, in the case of the refrigerator using the electronic damper, the damper is left open during the continuous operation of the compressor and the fan motor.
이상과 같이 본 발명의 온도 제어방법에 의하면, 냉장실의 고내온도가 이상 상승할 경우 온도상승 정도에 따라 팬모우터와 압축기를 선택적으로 연속가동 시킨으로서, 냉장실의 고내 온도를 단시간내에 정상 냉장온도로 강하시켜 주므로, 냉장식품의 신선도를 높이고 보관 가능 시간을 길게 할 수 있는 등의 잇점이 있다.As described above, according to the temperature control method of the present invention, when the internal temperature of the refrigerating compartment rises abnormally, the fan motor and the compressor are selectively operated in accordance with the degree of temperature rise, so that the internal temperature of the refrigerating compartment is returned to the normal refrigerating temperature within a short time. As it lowers, the freshness of the refrigerated food can be increased and the storage time can be extended.
