본 발명은 냉장실과 냉동실의 압축기 운전주기를 별도로 적산하여 냉장실의 제상주기를 냉동실에 비해 길게 가져감으로써 냉장실에 보관중인 김치의 숙성을 최대한 지연시킬 수 있는 냉동냉장고의 제상운전 제어방법에 관한 것이다. The present invention relates to a defrosting operation control method of the refrigerator freezer that can delay the ripening of the kimchi stored in the refrigerator compartment by maximizing the compressor operation cycle of the refrigerator compartment and the freezer compartment longer than the freezer compartment.

잘 알려진 바와 같이 냉장고의 증발기 내에서 액상의 냉매가 증발할 때 그 주위로부터 뺏은 증발열로써 냉장고의 냉각이 행해진다. 이때 증발기에는 주위의 수분이 얼어붙음으로써 성에가 끼게 되는데, 이 같은 성에는 증발기 효율을 크게 저하시키는 주요인이 되므로 제거하여 줄 필요가 있다. 따라서 냉장고에는 그 증발기에 붙어 있는 성에를 녹이도록 전기 발열되는 제상용 히터와 이를 적절히 제어하는 수단이 구비되고 있다. 여기서, 상기한 증발기는 냉장고의 냉각 성능을 향상시키기 위해 냉장실과 냉동실에 각각 전용으로 설치되고 있는 추세에 있으며, 이에 따라 상기한 제상 히터도 냉동실 제상 히터와 냉장실 제상 히터로 분리되어 설치되고 있는 추세에 있다. As is well known, when a liquid refrigerant evaporates in an evaporator of a refrigerator, cooling of the refrigerator is performed by evaporation heat taken from the surroundings. At this time, the frost is trapped by the freezing of moisture around the evaporator, and this frost is required to be removed because it becomes a major deterioration in the evaporator efficiency. Therefore, the refrigerator is provided with a defrost heater that generates electricity to melt frost attached to the evaporator and means for appropriately controlling the frost heater. Here, the evaporator is in a trend that is installed in each of the refrigerating compartment and the freezing chamber to improve the cooling performance of the refrigerator, and accordingly, the defrost heater is also installed separately from the freezer defrost heater and the refrigerator compartment defrost heater. have.

도 1에 2개의 증발기를 갖는 냉장고의 제상 운전을 위한 냉장고의 일부 블록 구성을 개략적으로 나타내 보였다. 도 1을 참조하면, 냉동실 제상 히터(2) 및 냉장실 제상 히터(4)는 히터 구동부(5)에 의해 구동 발열되며, 히터 구동부(5)는 마이크로컴퓨터를 포함하는 제어부(10)에 의해 제어된다. 냉동실 증발기(1) 및 냉장실 증발기(3)의 제상 상태는 온도센서로 이루어지는 제상상태 감지부(8)에 의해 감지 되어 마이크로컴퓨터 제어부(10)에 입력된다. 압축기(6)는 압축기 구동/감지부(7)에 의해 구동되며, 그 구동상태 또한 압축기 구동/감지부(7)에 의해 감지되어 마이크로컴퓨터 제어부(10)에 입력된다. 1 schematically illustrates a block configuration of a refrigerator for defrosting a refrigerator having two evaporators. Referring to FIG. 1, the freezer compartment defrost heater 2 and the refrigerating compartment defrost heater 4 are driven to generate heat by a heater driver 5, and the heater driver 5 is controlled by a controller 10 including a microcomputer. . The defrost state of the freezer compartment evaporator 1 and the refrigerating compartment evaporator 3 is detected by the defrost state detection unit 8 composed of a temperature sensor and input to the microcomputer controller 10. The compressor 6 is driven by the compressor drive / detector 7, and its driving state is also detected by the compressor drive / detector 7 and input to the microcomputer controller 10.

상기와 같은 냉장고의 제상운전을 위한 구성의 제상 운전방법을 도 3을 참조하여 설명하면 다음과 같다. The defrosting operation method of the configuration for defrosting the refrigerator as described above will be described with reference to FIG. 3.

도 3에서 마이크로 컴퓨터 제어부(10)는 압축기 구동/감지부(7)를 통해 압축기(6)가 운전상태에 있는지를 판단하여(단계 S10), 압축기(6)가 운전하는 동안의 운전시간을 계속하여 적산한다(단계 S12). 이렇게 적산된 압축기 운전 시간이 소정 시간, 바람직하게는 6시간이 되었는지 판단하고(단계 S14), 6시간이 되면 압축기(6)의 운전을 강제로 정지시킨다(단계 S16).In FIG. 3, the microcomputer control unit 10 determines whether the compressor 6 is in an operating state through the compressor driving / detecting unit 7 (step S10), and continues the operation time while the compressor 6 is operating. To integrate (step S12). It is determined whether the accumulated compressor operation time has reached a predetermined time, preferably 6 hours (step S14), and when 6 hours is reached, the operation of the compressor 6 is forcibly stopped (step S16).

다음, 마이크로컴퓨터 제어부(10)는 온도센서로 이루어져 각 증발기(1)(3)의 온도상태를 검출하여 검출된 온도에 따라 각 증발기(1)(3)의 제상조건을 판단토록 하는 제상상태 감지부(8)로부터 신호를 입력받아 상기 냉동실 증발기(1) 및 냉장실 증발기(3) 모두가 제상조건에 해당되었다고 판단하면, 즉 냉장실 및 냉동실의 증발기(1)(3)의 온도가 제상온도에 이르렀으면(단계 S18), 히터 구동부(5)를 제어하여 냉동실 제상히터(2) 및 냉장실 제상히터(4)가 작동되도록 한다(단계 S20). 냉동실 제상히터(2) 및 냉장실 제상히터(4)가 작동되면, 그 작동열에 의해서 냉동실 증발기(1) 및 냉장실 증발기(3)의 제상이 동시에 이루어지게 된다. Next, the microcomputer control unit 10 is formed of a temperature sensor to detect the temperature state of each evaporator (1) (3) to detect the defrost state to determine the defrost condition of each evaporator (1) (3) according to the detected temperature Upon receiving a signal from the unit 8 and determining that both the freezer compartment evaporator 1 and the refrigerator compartment evaporator 3 correspond to the defrost condition, that is, the temperatures of the evaporators 1 and 3 of the refrigerator compartment and the freezer compartment have reached the defrost temperature. On the other hand (step S18), the heater driving unit 5 is controlled to operate the freezer compartment defrost heater 2 and the refrigerator compartment defrost heater 4 (step S20). When the freezer compartment defrost heater 2 and the refrigerating compartment defrost heater 4 are operated, defrosting of the freezer compartment evaporator 1 and the refrigerator compartment evaporator 3 is simultaneously performed by the operating heat.

상기와 같이 해서 냉동실 증발기(1) 및 냉장실 증발기(3)의 제상이 동시에 이루어질 때, 제상상태 감지부(8)로부터 상기 각 증발기(1)(3)의 제상이 모두 완료 되었다는 신호가 출력되어 마이크로컴퓨터 제어부(10)에 입력되면, 마이크로컴퓨터 제어부(10)는 히터 구동부(5)를 통해 제상 히터(24)의 발열상태, 즉 제상 히터(24) 발열체로의 전류인가를 중지시켜 각 증발기(1)(3)의 제상을 종료시킨다(단계 S22). When defrosting of the freezer compartment evaporator 1 and the refrigerating chamber evaporator 3 is performed simultaneously as described above, a signal indicating that the defrost of each of the evaporators 1 and 3 is completed from the defrost state detection unit 8 is output. When input to the computer control unit 10, the microcomputer control unit 10 stops the exothermic state of the defrost heater 24, that is, the current application to the heating element of the defrost heater 24 through the heater driver 5. The defrost of (3) is terminated (step S22).

그런데, 전술한 냉장고의 제상운전 형태는 도 2에 도시되어 있는 바와 같이 냉장실 증발기의 제상이 2회 수행될 때 냉동실 증발기의 제상이 1회 수행되는 방식으로 제상이 수행되기 때문에, 냉장실 증발기와 냉동실 증발기의 제상이 동시에 수행되는 경우에는 고내 온도의 상승폭이 커져 고내 식품의 신선도에 악영향을 미치는 문제점이 있었다. However, since the defrosting operation of the refrigerator described above is performed as the defrost of the freezer compartment evaporator is performed once when the defrost of the refrigerator compartment evaporator is performed twice as shown in FIG. 2, the refrigerator compartment evaporator and the freezer compartment evaporator are performed. If the defrosting is performed at the same time, there is a problem that the increase in the temperature in the refrigerator increases, adversely affecting the freshness of the food in the refrigerator.

즉, 종래 2개의 증발기를 갖는 냉장고의 제상 운전방법은 도 2에 도시한 바와 같이 압축기의 운전시간을 적산하여 특정시간에 도달하면 냉동실과 냉장실이 동시에 제상이 이루어지기 때문에, 제상주기 및 제상횟수는 같게 된다. That is, in the conventional defrosting operation method of a refrigerator having two evaporators, since the freezer compartment and the refrigerating compartment are defrosted at the same time by accumulating the operation time of the compressor as shown in FIG. 2, the defrost cycle and the number of defrosting are Becomes the same.

따라서, 냉동실과 냉장실의 제상 주기 및 회수가 같기 때문에 냉장실의 성에에 비해 제상이 빨리 이루어져 고내 온도가 설정온도 범위 이상으로 상승하면, 냉장실에 보관중인 김치인 경우에는 숙성이 빨라 소비자가 원하는 맛을 유지하면서 장시간 보관하는데 어려움이 있다. Therefore, since the defrosting cycle and the number of defrosting in the freezer compartment and the refrigerating compartment are the same, the defrost is faster than the refrigerating compartment. It is difficult to store for a long time.

본 발명은 전술한 문제를 해결하기 위하여 안출된 것으로, 냉동실과 냉장실의 압축기 운전시간을 각각 적산하여 냉동실의 제상주기와 냉장실의 제상주기를 별도로 행하여 김치의 숙성을 최대한 지연시키는 냉동냉장고의 제상운전 제어방법을 제공함에 그 목적이 있다. The present invention has been made in order to solve the above problems, the defrosting operation control of the refrigerator freezer to delay the ripening of kimchi as much as possible by performing the defrost cycle of the freezer compartment and the defrost cycle of the freezer compartment separately by integrating the compressor operation time of the freezer compartment and the refrigerating compartment, respectively The purpose is to provide a method.

전술한 목적을 달성하기 위한 본 발명에 따른 냉동냉장고의 제상운전 제어방법은 냉동실과 냉장실의 압축기 운전시간을 각각 적산하여, 냉동실의 제상주기와 냉장실의 제상주기를 별도로 제어하되, 상기 냉장실의 제상주기는 상기 냉동실의 제상주기에 비해 길게 제어되는 것을 특징으로 한다. The defrosting operation control method of the refrigerator freezer according to the present invention for achieving the above object is to accumulate the compressor operating time of the freezer compartment and the refrigerator compartment, respectively, to separately control the defrost cycle of the freezer compartment and the defrost cycle of the refrigerator compartment, defrost cycle of the refrigerator compartment Is controlled longer than the defrosting cycle of the freezer compartment.

본 발명의 다른 특징에 따른 냉동냉장고의 제상운전 제어방법은 냉동실의 운전주기와 냉장실의 운전시간을 각각 적산하는 단계; 상기 냉동실의 운전적산시간 또는 상기 냉장실의 운전적산시간이 설정시간에 도달하였는지를 판단하는 단계; 상기 냉동실의 운전적산시간 또는 상기 냉장실의 운전적산시간이 설정시간에 도달하면, 냉동실 또는 냉장실의 운전을 정지하고 냉동실 또는 냉장실의 제상 히터를 작동하는 단계를 포함하되, 상기 냉장실의 제상주기는 상기 냉동실의 제상주기에 비해 길게 제어되는 것을 특징으로 한다. Defrosting operation control method of the refrigerator according to another aspect of the present invention comprises the steps of integrating the operation period of the freezer compartment and the operation time of the refrigerator compartment, respectively; Determining whether the operation integration time of the freezer compartment or the operation integration time of the refrigerating compartment has reached a set time; When the operation integration time of the freezer compartment or the operation integration time of the refrigerating compartment reaches a set time, stopping the operation of the freezer compartment or the refrigerating compartment and operating the defrost heater of the freezer compartment or the refrigerating compartment, the defrost cycle of the refrigerating compartment is the freezer compartment It is characterized in that it is controlled longer than the defrost cycle.

이들 방법에 의하면, 냉동실과 냉장실의 압축기 운전주기를 각각 적산하여 냉동실의 제상주기와 냉장실의 제상주기를 별도로 행하여 김치의 숙성을 최대한 지연시킬 수 있다. According to these methods, the kimchi operation can be delayed as much as possible by integrating the compressor operation cycles of the freezer compartment and the refrigerating compartment, respectively, and separately performing the defrost cycle of the freezer compartment and the defrost cycle of the refrigerator compartment.

이하, 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 설명한다. Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described.

도 4는 본 발명의 바람직한 실시예에 따른 냉동냉장고의 제상운전 제어방법의 플로 차트이다. Figure 4 is a flow chart of the defrosting operation control method of the refrigerator according to a preferred embodiment of the present invention.

본 실시예의 냉동냉장고의 제상운전 제어방법은 냉동실과 냉장실의 압축기 운전시간을 각각 적산하여, 냉동실 운전적산시간 또는 냉장실 운전적산시간이 설정시간에 도달하거나 경과한 경우 냉장실의 제상주기를 냉동실의 제상주기보다 길게 제어하는 것이다. In the defrosting operation control method of the refrigerator refrigerator according to the present embodiment, the compressor operation time of the freezer compartment and the refrigerating compartment are respectively accumulated, and the defrosting cycle of the refrigerating compartment is performed when the freezer operation integration time or the refrigerating compartment operation integration time reaches or passes the set time. Longer control.

이를 도 4에 도시한 바와 같이 분설하면 다음과 같다. When divided as shown in Figure 4 as follows.

먼저 압축기의 운전 여부를 판단한다(S110). 통상 냉동실의 압축기 운전주기는 짧고 기동시간은 길다. 반대로, 냉장실의 압축기 운전주기는 길고 기동시간 짧다. First, it is determined whether the compressor is operating (S110). Normally, the compressor operation cycle of the freezer compartment is short and the starting time is long. In contrast, the compressor operation cycle of the refrigerating chamber is long and the startup time is short.

압축기가 운전하면, 냉동실이 운전되는지를 판단한다(S112). When the compressor operates, it is determined whether the freezer compartment is operated (S112).

압축기의 운전이 냉동실의 운전인 경우에는 냉동실의 운전시간을 적산한다(S114). When the operation of the compressor is the operation of the freezer compartment, the operation time of the freezer compartment is integrated (S114).

그 다음, 냉동실의 운전적산시간이 설정시간(h1)에 도달했는지를 판단한다(S116). Next, it is determined whether the operation integration time of the freezer compartment has reached the set time h1 (S116).

냉동실의 운전적산시간이 설정시간(h1)에 도달하면, 냉동실의 운전을 정지하고(S118), 냉동실 제상 히터를 작동하여(S120) 냉동실 증발기의 성에를 제거한다. When the operation integration time of the freezer compartment reaches the set time h1, the operation of the freezer compartment is stopped (S118), and the freezer compartment defrost heater is operated (S120) to remove the frost of the freezer compartment evaporator.

한편, 압축기의 운전이 냉동실의 운전이 아닌 경우, 냉장실이 운전되는지를 판단한다(S212). On the other hand, if the operation of the compressor is not the operation of the freezer compartment, it is determined whether the refrigerator compartment is operated (S212).

압축기의 운전이 냉동실의 운전인 경우에는 냉장실의 운전시간을 적산한다(S214). If the operation of the compressor is the operation of the freezer compartment, the operation time of the refrigerating compartment is integrated (S214).

그 다음, 냉장실의 운전적산시간이 설정시간(h2)에 도달했는지를 판단한 다(S216). Next, it is determined whether the operation integration time of the refrigerating compartment has reached the set time h2 (S216).

냉장실의 운전적산시간이 설정시간(h2)에 도달하면, 냉장실의 운전을 정지하고(S218), 냉장실 제상 히터를 작동하여(S220) 냉장실 증발기의 성에를 제거한다. When the operation integration time of the refrigerator compartment reaches the set time (h2), the operation of the refrigerator compartment is stopped (S218), the refrigerator compartment defrost heater is operated (S220) to remove the frost of the refrigerator compartment evaporator.

냉동실의 운전적산시간이 냉장실의 운전적산시간보다 길기 때문에, 설정시간(h1)는 설정시간(h2)과 같게 하거나 길게 하여, 냉장실의 제상운전주기를 냉동실의 제상운전주기보다 길게 행할 수 있다. Since the operation integration time of the freezer compartment is longer than the operation integration time of the refrigerator compartment, the set time h1 can be made equal to or longer than the set time h2 so that the defrosting operation cycle of the refrigerating compartment can be performed longer than the defrosting operation cycle of the freezer compartment.

이와 같이 제상주기를 냉장실과 냉동실의 룸별로 행하기 때문에, 냉장실의 제상주기를 냉동실에 대해 길게 가져감으로써, 냉장실에 보관중인 김치의 숙성을 최대한 지연시킬 수 있다. Since the defrosting cycle is performed for each room of the refrigerating compartment and the freezing chamber in this manner, the defrosting cycle of the refrigerating compartment is kept longer for the freezing compartment, whereby the ripening of the kimchi stored in the refrigerating compartment can be delayed as much as possible.

이상의 설명은 비록 한정된 실시예와 그 도면에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않고, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술 사상과 아래에 기재될 특허청구범위의 균등범위 내에서 다양한 수정 및 변형할 수 있음은 당업자라면 자명하다 할 것이다. Although the foregoing description has been described by means of a limited embodiment and the drawings, the invention is not limited thereto, and will be described below by the person skilled in the art to which the present invention pertains. It will be apparent to those skilled in the art that various modifications and variations can be made within the equivalent scope of the claims.

이상의 설명으로부터 명백하듯이, 본 발명에 따른 냉동냉장고의 제상운전 제어방법에 의하면, 냉동실과 냉장실의 압축운전시간을 별로로 적산하여 냉장실의 제상주기를 냉동실의 제상주기보다 길게 가져감으로써, 냉장실에 보관 중인 김치의 숙성을 최대한 지연시켜 소비자가 원하는 맛을 유지하면서 장시간 보관이 가능하다. As is apparent from the above description, according to the defrosting operation control method of the freezer according to the present invention, the decompression operation time of the freezer compartment and the refrigerating compartment is accumulated separately to bring the defrost cycle of the refrigerating compartment longer than the defrosting cycle of the freezer compartment. By delaying the ripening of kimchi in storage as much as possible, it can be stored for a long time while maintaining the taste desired by consumers.
