본 발명은 김치냉장고의 온도제어방법에 관한 것으로, 보다 상세하게는 외기온도의 변화에 따라 김치냉장고의 고내온도를 제어하는 김치냉장고의 온도제어방법이다.The present invention relates to a temperature control method of a kimchi refrigerator, and more particularly, to a temperature control method of a kimchi refrigerator to control the internal temperature of the kimchi refrigerator according to the change in the outside temperature.

일반적으로, 배추나 무와 같은 야채류에 각종 양념을 첨가한 다음 이를 적절히 숙성시켜 만든 김치는 아주 오래전부터 애용해 오는 발효식품으로서, 추운 겨울철에는 많은 양의 김치를 저장하였다가 조금씩 꺼내 먹기도 하였다. In general, kimchi made by adding various seasonings to vegetables such as cabbage and radish and then ripening it properly is a fermented food that has been a favorite for a long time, and in winter, a large amount of kimchi was stored and eaten little by little.

냉장고가 없었던 과거에는 더운 여름철에 김치를 저장하기가 상당히 힘들었으나, 냉장고의 등장으로 여름철에도 보다 장기간 동안 김치를 보관할 수 있게 되었다. In the past, when there was no refrigerator, it was quite difficult to store kimchi in hot summer, but with the advent of refrigerators, it was possible to store kimchi for longer periods in summer.

그러나, 냉장고를 자주 열고 닫는 과정에서 냉장고 내부온도가 심하게 변화되고 김치를 다른 그릇에 담기 위해 냉장고 밖으로 김치통을 꺼내는 도중에 외부 공기와의 접촉에 의해서 김치의 보존기간이 짧아지고, 김치의 숙성상태를 알맞게 유지하기가 매우 어려웠다.However, during the frequent opening and closing of the refrigerator, the internal temperature of the refrigerator is severely changed, and the preservation period of the kimchi is shortened by contact with the outside air while the kimchi container is taken out of the refrigerator to put kimchi in another bowl. It was very difficult to keep fit.

이에 따라, 계절의 변화 및 사용자의 기호에 따라 김치를 적당히 숙성시킨 다음, 적정온도로 유지하여 잘 익은 김치의 맛을 오랫동안 보존할 수 있도록 한 김치냉장고가 개발되었다.Accordingly, kimchi refrigerators have been developed in which the kimchi is appropriately aged according to the change of seasons and the preferences of the user, and then maintained at an appropriate temperature to preserve the taste of ripe kimchi for a long time.

이러한 김치냉장고는 냉각장치와 가열장치가 구비되어 있어, 초기에는 가열장치를 이용하여 빠른 시간내에 저장고에 저장되어 있는 김치를 기호에 맞게 숙성시킨 다음, 냉각장치를 이용하여 저장고의 온도를 적정수준으로 유지함으로써, 김치의 맛과 신선도를 장기간 보존하였다.These kimchi refrigerators are equipped with a cooling device and a heating device. Initially, the kimchi stored in the storage room is aged according to the preferences using a heating device, and then the temperature of the storage room is adjusted to a suitable level using the cooling device. By maintaining, the taste and freshness of kimchi were preserved for a long time.

그러나 김치냉장고는 저장고들의 고내온도를 미리 정해진 기준온도와 비교하여 고내온도에 따라 냉각장치와 가열장치를 반복적으로 작동시켜 김치의 숙성 및 보존에 충분히 대처할 수 있었으나 외부의 온도변화에는 민감하게 대처하지 못하는 단점이 있었다. However, the Kimchi Refrigerator was able to cope with the ripening and preservation of Kimchi by repeatedly operating the cooling system and heating device according to the internal temperature by comparing the internal temperature of the reservoirs with the predetermined reference temperature, but it was not sensitive to external temperature changes. There was a downside.

즉, 김치냉장고의 외기온도가 급격히 상승할 경우에는 김치냉장고가 가열됨으로 인해 고내온도가 상승하게 되어 정상 제어온도를 벗어나게 되고, 외기온도가 급격히 하강할 경우에는 김치냉장고가 냉각됨으로 인해 고내온도가 하강하게 되어 정상 제어온도를 벗어나게 되었다.In other words, if the outside temperature of the Kimchi refrigerator rises sharply, the inside temperature of the Kimchi refrigerator rises due to the heating of the Kimchi refrigerator, which is outside the normal control temperature. If the outside temperature of the Kimchi refrigerator falls rapidly, the inside temperature of the Kimchi refrigerator decreases It is out of the normal control temperature.

따라서, 외부의 온도변화에 민감하게 대처하지 못하여 외기온도가 급격히 올라가거나 내려갈 경우, 김치를 장시간 생생하게 보관할 수 없었고, 김치의 쓴맛이 증가되는 문제점이 있었다.Therefore, when the outside temperature is rapidly raised or lowered due to the failure to cope with the external temperature change, the kimchi could not be vividly stored for a long time, and there was a problem that the bitter taste of kimchi is increased.

이에 따라, 외기온도에 능동적으로 대처하기 위해서, 김치냉장고의 주변 온도를 측정하는 외기온도센서를 구비하여 외기온도가 상승하면, 고내온도를 정상모드 구동시보다 저온으로 제어하고, 반면에 외기온도가 하강하면, 고내온도를 정상모드 구동시보다 고온으로 제어함으로써 상기한 외기온도의 변화에 대응하여 고내온도를 선형적으로 제어하였다.Accordingly, in order to actively cope with the outside temperature, when the outside temperature rises with an outside temperature sensor that measures the ambient temperature of the Kimchi refrigerator, the inside temperature is controlled to be lower than that of the normal mode operation, while the outside temperature is When lowered, the internal temperature was linearly controlled in response to the above-mentioned change in the outside air temperature by controlling the internal temperature at a higher temperature than in the normal mode driving.

그러나 종래 기술에 따른 김치냉장고는 외기온도의 변화에 따라 고내온도를 선형적으로 제어하였으나, 통상 실외와 7℃~10℃ 정도의 온도차이를 보이는 베란다, 발코니 등에 설치된 김치냉장고는 일교차가 큰 봄이나 가을철엔 외기온도차가 크게 발생하게 되고 이러한 외기온도차에 따라 고내온도를 선형적으로 제어함으로써 김치의 과냉 또는 과숙성이 발생하게 되는 문제점이 있었다.However, the kimchi refrigerator according to the prior art linearly controlled the internal temperature according to the change in the outside temperature, but the kimchi refrigerator installed in the balcony or balcony having a temperature difference of about 7 ° C. to 10 ° C. in general, the spring has a large daily cross There was a problem that the outside air temperature difference is greatly generated in autumn and the supercooling or over-maturation of kimchi occurs by linearly controlling the internal temperature in accordance with the outside temperature difference.

예를 들어 야간의 외기온도가 1℃, 주간의 외기온도가 10℃인 봄철에 베란다에서 김치냉장고를 동작시킬 경우, 야간의 베란다 외기온도는 1℃ 에 7℃~10℃ 온 도만큼 상승하여 8℃~11℃ 이고 주간의 베란다 외기온도는 10℃ 에 7℃~10℃ 온도만큼 하강하여 17℃~20℃ 이므로 하루 동안 실제 베란다의 외기온도차는 6℃~12℃ 발생하게 된다. For example, if the Kimchi Refrigerator is operated on the veranda in the spring when the outside air temperature is 1 ℃ at night and the outside temperature is 10 ℃ during the day, the outside air temperature at night increases by 7 ℃ ~ 10 ℃ at 1 ℃. The temperature of the veranda outside the daytime is lowered by 7 ℃ ~ 10 ℃ to 10 ℃ and the temperature is 17 ℃ ~ 20 ℃. Therefore, the actual air temperature difference of the veranda during the day is 6 ℃ ~ 12 ℃.

따라서, 종래 기술에 따른 김치냉장고는 상기한 외기온도차를 그대로 적용하여 고내온도를 선형적으로 제어하게 되므로 김치가 과냉 또는 과숙성되는 문제점이 있었다.Therefore, the kimchi refrigerator according to the prior art has a problem that the kimchi is supercooled or over-mature because it is applied to the outside air temperature difference as it is to control the high internal temperature linearly.

이와 같은 문제점을 해결하기 위해 창안한 본 발명의 목적은 외기온도차가 기 설정된 설정온도 이상 발생하면 고내온도를 보상하여 정상적인 고내온도를 유지할 수 있도록 한 김치냉장고의 온도제어방법을 제공하는 데 있다.An object of the present invention devised to solve the above problems is to provide a temperature control method of a kimchi refrigerator to maintain a normal high temperature by compensating the high temperature when the outside temperature difference is more than a predetermined set temperature.

본 발명의 다른 목적은 외기온도의 변화에 능동적으로 대처하여 김치의 과냉 또는 과숙성을 방지하는 데 있다.Another object of the present invention is to actively cope with changes in the outside air temperature to prevent overcooling or over-maturation of kimchi.

상기와 같은 목적을 달성하기 위한 본 발명인 김치냉장고의 온도제어방법은Temperature control method of the kimchi refrigerator of the present invention for achieving the above object is

And a fourth step of controlling.

또한, 상기 제 4 단계는 상기 고내온도가 상기 정상모드의 고내제어온도범위를 초과하면 정상모드에서의 도달하고자 하는 고내제어온도를 상기 보상온도만큼 하강시키고, 미만이면 상기 보상온도만큼 상승시키는 것을 특징으로 한다.In the fourth step, if the high temperature exceeds the high temperature control temperature range of the normal mode, the high temperature control temperature to be reached in the normal mode is lowered by the compensation temperature, and if it is less than, the high temperature is increased by the compensation temperature. It is done.

아울러, 상기 기준온도는 현재 시점으로부터 바로 이전의 증가 또는 하강하다가 하강 또는 증가하게 되는 정점시의 외기온도인 것을 특징으로 한다.In addition, the reference temperature is characterized in that the outside air temperature at the time of the peak to increase or decrease immediately before the current time point is to be lowered or increased.

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

도 1 은 본 발명의 실시예에 따른 김치냉장고의 온도제어장치의 블럭도이고, 도 2 는 본 발명의 실시예에 따른 김치냉장고의 온도제어방법의 순서도이다.1 is a block diagram of a temperature control apparatus of a kimchi refrigerator according to an embodiment of the present invention, Figure 2 is a flow chart of the temperature control method of the kimchi refrigerator according to an embodiment of the present invention.

본 발명의 실시예에 따른 김치냉장고의 온도제어장치는 도 1 에 도시한 바와 같이, 김치냉장고의 주변 외기온도를 측정하여 주제어부(20)로 전송하는 외기온도센서(30), 김치냉장고의 고내온도를 측정하여 주제어부(20)로 전송하는 고내온도센서(40), 외기온도센서(30)와 고내온도센서(40)로부터 전송받은 온도값을 토대로 보상여부를 판단하고 히터(50)와 압축기(60) 및 표시부(10)를 제어하는 주제어부 (20), 주제어부(20)의 제어신호에 따라 온/오프 되어 김치냉장고의 고내온도를 상승시키는 히터(50), 주제어부(20)의 제어신호에 따라 온/오프 되어 김치냉장고의 고내온도를 하강시키는 압축기(60), 및 주제어부(20)의 제어신호에 따라 보상여부를 표시하는 표시부(10)를 포함하여 이루어진다.As shown in FIG. 1, the temperature control device of the kimchi refrigerator according to an embodiment of the present invention measures the ambient outside temperature of the kimchi refrigerator and transmits it to the main control unit 20. Determination of compensation based on the temperature value received from the high temperature sensor 40, the outside air temperature sensor 30 and the high temperature sensor 40 to measure the temperature and transmits it to the main controller 20, the heater 50 and the compressor 60 and the heater 50, the main controller 20 to turn on / off in accordance with the control signal of the main controller 20 to control the display unit 10 to increase the internal temperature of the kimchi refrigerator. Compressor 60 to be turned on / off according to the control signal to lower the internal temperature of the kimchi refrigerator, and the display unit 10 for displaying the compensation according to the control signal of the main control unit 20.

여기서, 상기한 히터(50) 및 압축기(60)를 제어하여 고내온도를 제어하는 과정은 종래기술과 동일한 것으로 이하에서 간단히 설명하면 다음과 같다.Here, the process of controlling the internal temperature by controlling the heater 50 and the compressor 60 is the same as in the prior art and will be described below briefly.

일반적으로 김치냉장고는 압축기와 응축기, 및 냉각팬, 히터 등이 설치되는데, 저장고에는 김치의 숙성을 위해 저장고의 고내온도를 소정 온도로 상승시키는 히터와 김치의 냉장 보관을 위해 냉매가 흐르는 증발기 파이프가 설치되어 주제어부의 제어에 따라 압축기와 히터가 동작함으로써 저장고의 고내온도를 제어한다.In general, Kimchi refrigerators are equipped with a compressor, a condenser, a cooling fan, a heater, and the like. A storage tank includes an evaporator pipe through which a refrigerant flows for the storage of the kimchi and a storage temperature of the kimchi. The compressor and the heater operate under the control of the main controller to control the internal temperature of the reservoir.

이는 당업자가 용이하게 실시할 수 있으므로 여기서는 그 상세한 설명을 생략한다.This can be easily carried out by those skilled in the art, so the detailed description thereof is omitted here.

한편, 주제어부(20)는 본 발명의 실시예에 따른 김치냉장고의 온도제어장치를 전반적으로 제어하는 것으로서, 첨부된 도 2 를 참조하여 상세히 설명한다.On the other hand, the main control unit 20 as the overall control the temperature control apparatus of the kimchi refrigerator according to an embodiment of the present invention, will be described in detail with reference to the accompanying FIG.

본 발명의 실시예에 따른 김치냉장고의 온도제어 방법은 도 2 에 도시한 바와 같이, 먼저 김치냉장고의 전원이 온된 후 외기온도센서(30)가 외기온도를 측정(S10)하여 주제어부(20)에 전송하면 주제어부(20)는 기 설정된 기준온도와 현재의 외기온도와의 온도차를 산출(S20)한 후 온도차가 기 설정된 설정온도, 바람직하게는 10℃ 이상인지 여부를 판단(S30)한다.In the method of controlling the temperature of a kimchi refrigerator according to an embodiment of the present invention, as shown in FIG. 2, first, after the power of the kimchi refrigerator is turned on, the outside air temperature sensor 30 measures the outside air temperature (S10) to control the main control unit 20. When transmitting to the main controller 20 calculates a temperature difference between the preset reference temperature and the current outside temperature (S20) and determines whether or not the temperature difference is a predetermined set temperature, preferably 10 ℃ or more (S30).

여기서, 온도차 산출에 기준이 되는 기준온도는 외기온도가 상승 또는 하강 하다가 하강 또는 상승하게 되는 정점시 외기온도로서, 현재 시점으로부터 바로 이전의 정점시 외기온도를 기준온도로 설정한다. 따라서 기준온도는 시간이 경과함에 따라 계속적으로 갱신된다.Here, the reference temperature, which is a reference for calculating the temperature difference, is an outdoor temperature at the time when the outside temperature rises or falls and then falls or rises, and sets the outside temperature at the time of the peak just before the present time as the reference temperature. Thus, the reference temperature is continuously updated over time.

참고로, 본 발명의 실시예에서는 설정온도를 10℃ 로 설정하였으나 이에 한정하지 않고 김치냉장고의 설치위치, 김치냉장고의 용량 등에 따라서 다양하게 변경 가능하다.For reference, in the exemplary embodiment of the present invention, the set temperature is set to 10 ° C., but the present invention is not limited thereto and may be variously changed according to the installation location of the kimchi refrigerator, the capacity of the kimchi refrigerator, and the like.

한편, 주제어부(20)는 온도차가 10℃ 미만일 경우에는 정상모드로 온도제어를 실시(S80)하고 온도차가 10℃ 이상일 경우에는 고내온도센서(40)에서 측정된 고내온도가 정상모드의 고내제어온도범위 이외인지 여부를 판단(S40)한다.On the other hand, the main controller 20 performs the temperature control in the normal mode when the temperature difference is less than 10 ℃ (S80), when the temperature difference is more than 10 ℃ internal temperature measured in the high temperature sensor 40 is the internal control of the normal mode It is determined whether or not the temperature range (S40).

여기서, 정상모드의 고내제어온도범위라 함은 현재 사용자가 설정한 김치냉장고의 동작모드에서 유지되어야할 고내온도범위를 의미한다.Here, the high temperature control temperature range in the normal mode means a high temperature range to be maintained in the operation mode of the kimchi refrigerator currently set by the user.

주제어부(20)는 고내온도가 정상모드의 고내제어온도범위 이내이면 정상모드로 고내온도를 제어(S80)하고, 반면에 고내온도가 정상모드의 고내제어온도범위 이외이면 종래와 같이 외기온도에 따라 고내온도를 선형제어할 뿐만 아니라 설정온도 이상의 온도차에 따른 온도보상과정을 수행한다.The main control unit 20 controls the internal temperature in the normal mode if the internal temperature is within the internal control temperature range of the normal mode (S80), while the internal temperature is outside the normal internal control temperature range in the normal mode. Therefore, not only the linear temperature control is performed but also the temperature compensation process is performed according to the temperature difference over the set temperature.

즉, 주제어부(20)는 고내온도가 정상모드의 고내제어온도범위 이외이면 고내온도가 정상모드의 고내제어온도범위를 초과하는지를 판단(S50)하여 고내온도가 정상모드의 고내제어온도범위 미만이면 히터(50)을 제어하여 도달하고자 하는 고내제어온도를 보상온도만큼 상승(S70)시키고, 고내온도가 정상모드의 고내제어온도범위를 초과하면 압축기(60)를 제어하여 도달하고자 하는 고내제어온도를 보상온도만큼 하강(S60)시킨다.That is, the main controller 20 determines whether the high temperature exceeds the high control temperature range of the normal mode when the high temperature is outside the high control temperature range of the normal mode (S50). Control the heater 50 to increase the internal control temperature to be reached by the compensation temperature (S70), and when the internal temperature exceeds the internal control temperature range of the normal mode, the compressor 60 is controlled to reach the internal control temperature to be reached. Lower by the compensation temperature (S60).

이러한 온도보상과정을 통해 외기온도차가 크게 발생하더라도 상기한 보상온도만큼 고내온도를 제어함으로써, 선형제어에 따른 김치의 과냉 및 과숙성을 방지할 수 있다.Even if a large difference in outside temperature occurs through the temperature compensation process, by controlling the high temperature inside as much as the compensation temperature, it is possible to prevent overcooling and over-maturation of kimchi due to linear control.

여기서, 보상온도라 함은 정상모드의 고내제어온도를 소정의 온도만큼 상승 또는 하강시키는 온도를 의미하며, 설정온도에 따라서 다양하게 변경 가능한데 여기서는 1℃~2℃ 로 설정한다. 이는 온도차가 설정온도 즉, 10℃ 이상 발생하면 고내온도가 실제로 1℃~2℃ 만큼 변화하기 때문이다.Here, the compensation temperature means a temperature for raising or lowering the internal control temperature of the normal mode by a predetermined temperature, and may be variously changed according to the set temperature, and here, the temperature is set to 1 ° C to 2 ° C. This is because if the temperature difference occurs above the set temperature, that is, 10 ° C, the internal temperature of the refrigerator actually changes by 1 ° C to 2 ° C.

아울러, 주제어부(20)는 고내제어온도를 보상온도 만큼 상승(S70) 또는 하강(S60)하여 온도제어를 실시하고 있는 경우 보상적용 여부를 표시부(10)에 전송하여 표시부(10)가 보상적용 여부를 표시하도록 한다.In addition, the main control unit 20 increases the internal control temperature by the compensation temperature (S70) or decreases (S60) when the temperature control is performed, and transmits whether the compensation is applied to the display unit 10, and the display unit 10 applies the compensation. Indicate whether or not.

본 발명은 도면에 도시된 실시예를 참고로 하여 설명되었으나, 이는 예시적인 것에 불과하며, 당해 기술이 속하는 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다.Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. Will understand.

한편 상기의 김치냉장고의 온도제어방법은 김치냉장고에만 한정되어 적용 가능한 것이 아니라 베란다 등 외기온도차가 크게 발생하는 가혹환경에 설치되는 냉장고, 반찬냉장고, 와인냉장고 등의 제품 및 외기온도차에 따른 제어가 필요한 물의 온도를 제어하는 정수기, 공기의 온도를 제어하는 공기조화기, 냉·온풍기 등에 적용 가능할 것이다.On the other hand, the temperature control method of the Kimchi refrigerator is not limited to the Kimchi refrigerator and is applicable to the Kimchi refrigerator. It may be applied to a water purifier that controls the temperature of water, an air conditioner that controls the temperature of air, and a cold / hot air fan.

이와 같이 구성되는 본 발명에 따르면, 베란다 등 외기온도차가 큰 가혹환경에서 그 환경에 따른 온도제어를 함으로써 보관식품의 안정적 온도제어 및 보관물의 과냉 및 과숙성을 예방하고 외기온도차에 따른 제어가 필요한 기타제품의 안정적인 제어를 가능하게 해준다.According to the present invention configured as described above, the temperature control according to the environment in a harsh environment with a large outdoor temperature difference, such as a veranda, to control the stable temperature of the stored food and to prevent overcooling and over-maturation of the storage, and the control according to the outdoor temperature difference It enables stable control of the product.
