본 발명은 냉장고에 관한 것으로, 특히 냉장고 고내의 가스와 저장된 식품의 중량을 이용하여 선도를 감지하고, 부패시 사용자에게 알리기 위한 냉장고 선도감지장치 및 그의 제어방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator, and more particularly, to a refrigerator freshness detecting device and a control method thereof for detecting freshness using a gas in a refrigerator and a weight of stored food and informing a user in case of corruption.
종래의 냉장고는, 제1도에 도시한 바와 같이 보관중인 각 식품의 선도 정도를 알 수 있도록 상기 식품에서 발생되는 가스를 감지하기 위한 가스 감지부(1)와, 상기 가스 감지부(1)의 감지신호를 분석하여 기준치 이상의 가스가 발생되는 경우, 즉 부패하여 냄새가 나는 경우 이를 사용자에게 알리도록 제어신호를 발생하는 마이크로 컴퓨터(15)와, 상기 마이크로 컴퓨터의 제어신호에 따라 사용자가 알 수 있도록 경고음을 울리거나 메세지를 발생하는 메세지 발생부(20)로 구성되며, 제2도를 참조하여 상기 마이크로 컴퓨터의 상세동작을 설명하면 다음과 같다.As shown in FIG. 1, the conventional refrigerator includes a gas detector 1 for detecting a gas generated from the food and a gas detector 1 so as to know the freshness of each food being stored. The microcomputer 15 generating a control signal to notify the user when a gas of more than a reference value is generated by analyzing the detection signal, that is, a odor due to corruption, so that the user can know according to the control signal of the microcomputer. It consists of a message generating unit 20 that sounds a warning sound or generates a message, the detailed operation of the microcomputer will be described with reference to FIG.
먼저 상기 가스감지부에서 식품에서 발생되는 가스, 즉 냄새를 감지하여 입력하면, 먼저 냄새 종류별로 식품을 분류하고, 분류된 식품별로 해당 기준치와 비교한다.First, when the gas detection unit detects and inputs a gas generated from a food, that is, an odor, the food is first classified by odor type and compared with the corresponding reference value for each classified food.
상기 식품별로 발생되는 가스를 살펴보면, 생선, 무우, 양파등에서는 메칠 메루캅탄이 발생되고, 생선, 육류, 양배추, 마늘등에서는 디메틸아세테이트가 발생되며, 상기 생선과 육류의 경우에는 암모니아 가스도 발생되며, 또한 달걀이나 메추리알과 같은 알종류에서는 황화수소가 발생되므로 이러한 식품별 발생 가스에 대한 기준치를 마이크로 컴퓨터(15)내의 메모리에 저장하여 두고 첨가 또는 삭제하여 보관중인 식품에 대한 부패 정도를 판단할 수 있도록 한다.Looking at the gas generated by each food, methyl mercaptan is generated in fish, radishes, onions, etc., dimethyl acetate is generated in fish, meat, cabbage, garlic, etc., and ammonia gas is also generated in the fish and meat. In addition, since hydrogen sulfide is generated in egg types such as eggs and quail eggs, the reference value for the gas generated by each food is stored in the memory in the microcomputer 15 and added or deleted to determine the degree of corruption of the stored food. Make sure
즉, 상기와 같이 분류된 식품별로 상기 마이크로 컴퓨터 내의 메모리에 저장된 해당 기준치와 비교하여 그 값이 기준치 이상이면 부패한 것이므로 경보음을 발생하거나 또는 냉장고의 전면판넬을 통해 감지된 식품의 종류를 표시한다.That is, compared to the reference value stored in the memory in the microcomputer for each of the food classified as described above, if the value is more than the reference value is a corruption, so it generates an alarm sound or displays the type of food detected through the front panel of the refrigerator.
그러나 이러한 종래 기술에 의한 냉장고는, 냉장고내에 식품을 장시간 보관하는 경우, 보간중에 식품의 증량 및 감소가 많이 일어나 식품의 상태가 변질되어도 냄새강도가 낮게 나타거나 초기의 신선한 식품에서는 냄새 강도가 높게 나타나 부패로 오인할 수 있기 때문에 사용자가 보관중인 식품의 선도판별에 대해 신뢰할 수 없으며, 상기 보관식품의 상태나 양에 관계없이 온도조절이 이루어지므로 식품과냉 또는 미생물과 자체효소등에 의한 부패가 발생하는 문제점이 있다.However, the refrigerator according to the related art shows that when the food is stored in the refrigerator for a long time, the increase and decrease of the food occurs during interpolation, so that the odor intensity is low even when the state of the food is changed, or the smell is high in the fresh food. Because it can be mistaken for corruption, it is unreliable for the user to determine the freshness of the food being stored, and because the temperature is controlled regardless of the state or quantity of the stored food, there is a problem of corruption due to food supercooling or microorganisms and self enzymes. There is this.
따라서 본 발명의 목적은 상기와 같은 문제점을 해결하기 위하여 보관식품에서 발생하는 가스뿐만 아니라 보관식품의 중량을 감지하여 선도를 판별하고, 적절한 온도조절 및 선도 판별후 탈취함으로써 각 선도 판별에 대한 정확도를 높일 수 있는 냉장고 선도감지장치를 제공하는 것이다.Accordingly, an object of the present invention is to determine the freshness by detecting the weight of the stored food as well as the gas generated from the stored food in order to solve the above problems, and by deodorizing after appropriate temperature control and freshness to determine the accuracy of each freshness It is to provide a refrigerator leading detection device that can be increased.

이하 첨부도면을 참조하여 본 발명을 좀 더 상세하게 설명하고자 한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
본 발명의 냉장고 선도감지장치는, 제3도에 도시한 바와 같이 종래의 가스감지외에 식품이 올려지는 선반의 모서리측에 중량감지부(31)를 연결하고, 또한 고내의 온도를 감지하기 위한 온도감지부(32)를 더 연결함으로써 가스농도, 식품의 중량 및 고내온도등의 복합적인 요인들에 의해 선도를 정확히 판별할 수 있도록 한다.In the refrigerator freshness detecting device of the present invention, as shown in FIG. 3, the weight sensing unit 31 is connected to the edge side of the shelf where the food is placed in addition to the conventional gas sensing, and also the temperature sensing for sensing the temperature in the refrigerator. By further connecting the unit 32, it is possible to accurately determine the diagram by the complex factors such as gas concentration, food weight and high internal temperature.
그리고 상기 식품의 중량 감소율에 따라 냉각팬 제어부(37)를 통해 냉각팬을 구동하여 보관식품에 적절한 온도를 제공하고, 또한 가스농도에 따라 탈취장치 구동부(38)를 통해 탈취장치를 구동시켜 냉장고내를 탈취하도록 한다.In addition, the cooling fan controller 37 drives the cooling fan according to the weight reduction rate of the food to provide an appropriate temperature to the stored food, and also drives the deodorizer through the deodorizer driving unit 38 according to the gas concentration. To deodorize.
상기 중량 감소율은 연산부(35)를 통해 연산하며, 상기 각 복합적인 요인들에 의해 판별된 선도는 메세지 발생부(36)를 통해 사용자가 알 수 있도록 표시한다.The weight reduction rate is calculated by the calculation unit 35, and the diagram determined by the complex factors is displayed so that the user can know through the message generation unit 36.
제4도를 참조하여 이러한 냉장고 선도감지장치의 제어방법을 살펴보면, 먼저 사용자가 냉장고 문을 열고 식품을 고내에 투입하면 식품의 초기부하량을 감지하고 냉기 송풍팬을 동작시켜 초기보관식품에 대해 냉각작용을 수행하며, 이때 상기 가스 감지부에서 가스를 감지하여 초기식품의 종류를 인식한다.Referring to FIG. 4, the control method of the freshness sensor of the refrigerator is as follows. First, when the user opens the refrigerator door and puts the food into the refrigerator, it detects the initial load of the food and operates the cold air blower to cool the initial stored food. In this case, the gas detection unit detects the gas to recognize the type of initial food.
이때 상기 온도감지부에 의해 냉기 덕트(DUCT)를 온, 오프(ON/OFF) 제어하여 일정온도(To = 3℃ ± 1℃) 로 유지하며, 상기 식품저장실의 가스농도는 경과시간별 기준치와 비교하여 식품의 선도를 사용자가 알 수 있도록 표시한다.At this time, by controlling the temperature of the cold air duct (DUCT) on, off (ON / OFF) by maintaining a constant temperature (To = 3 ℃ ± 1 ℃), the gas concentration of the food storage room compared with the reference value for each elapsed time Display the freshness of the food so that the user knows.
상기와 같이 냉각 송풍팬의 운전이 계속되면서 보관식품의 휘발성 발생가스와 수분은 냉기 흡입구를 통해 냉동실로 이동되며, 또한 냉장고내 식품은 조금씩 건조되므로 제5도에 도시한 바와 같이 중량감소가 일어난다.As operation of the cooling blower fan continues, the volatile generation gas and moisture of the stored food are moved to the freezing chamber through the cold air inlet, and the food in the refrigerator is dried little by little, as shown in FIG. 5.
이러한 식품중량의 변화는, 운전이 진행되면서 계속적으로 식품의 중량을 중량감지부에서 감지하여 연산부를 통해 초기중량에 대한 중량감소율로 연산되어 마이크로 컴퓨터에 인식되며, 상기 감지된 가스농도와 중량감소율을 경과시간별로 기준치와 비교하여 냉장고내 상태를 제어한다.Such a change in food weight is continuously recognized as a weight loss rate for the initial weight through the operation unit by detecting the weight of the food in the weight sensing unit as the operation proceeds and is recognized by the microcomputer, the detected gas concentration and the weight loss rate has elapsed. The state in the refrigerator is controlled by comparison with the reference value by time.
즉, 상기 중량감소율이 최대값(G0)에 도달할때까지 소요되는 시간을 t0라고 하면, 상기 t0에서 중량감소율이 5%~10%일때는 식품의 선도가 급격히 저하되므로 냉각팬을 동작시켜 습냉기송풍으로 항온유지 및 이에 대한 메세지를 표시한다.That is, when the time required for the weight loss rate to reach the maximum value (G 0 ) is t 0 , when the weight loss rate is 5% to 10% at t 0 , the freshness of the food is sharply lowered. It operates and displays the temperature and the message about the constant temperature by the humid cold air blowing.
한편 상기 t0시간까지의 저장기간동안 상기 중량감소율이 최대값 이하일때는 식품이 신선한 상태로 유지되며, 이때도 역시 이에 대한 메세지를 표시한다.On the other hand, when the weight loss ratio is less than or equal to the maximum value during the storage period up to time t 0 , the food is kept fresh, and the message for this is also displayed.
또한 냉장고내에 발생된 가스, 즉 냄새를 탈취하기 위해서는 초기 식품의 종류분류를 확인한 상태로 상기 습냉기 송풍을 중단하고, 중량 변화율 및 가스농도를 복합인식한 후 상기 가스농도가 기준치 이상이면 탈취장치를 구동하며, 최적작동시간(t1)이 경과한 후 현재의 식품가스농도를 초기화하고 이러한 과정을 n회 반복하면서 가스농도가 기준치 이상인가를 감지하여 감지 결과를 사용자가 알 수 있도록 메세지를 표시한다.In addition, in order to deodorize the gas generated in the refrigerator, that is, the odor, the blowing of the wet and cold air is stopped while confirming the type classification of the initial food, and after combining the weight change rate and the gas concentration, the deodorizing apparatus is operated. After the optimal operating time (t 1 ) has elapsed, the current food gas concentration is initialized and the process is repeated n times, detecting whether the gas concentration is higher than the standard value and displaying a message so that the user can know the detection result. .
이상에서와 같이 본 발명에 의하면, 보관식품의 선도상태를 판단하여 최적저장 환경을 제공함으로써 냉장고의 온도를 자동제어하고, 식품의 식용 한계성 상태표현이 가능하며, 가스농도와 중량감소율을 이용하여 식품 선도의 상관관계를 판단함으로써 냉기 송풍의 작동제어와 탈취를 수행하여 위생적으로 식품을 저장할 수 있고, 또한 상기와 같이 복합적인 요인으로 선도를 판별함으로써 선도판별에 대한 신뢰성을 높일 수 있는 효과가 있다.As described above, according to the present invention, it is possible to automatically control the temperature of the refrigerator by determining the leading state of the stored food and to provide an optimal storage environment, to express the edible limit state of the food, and to use the gas concentration and the weight reduction rate. By determining the correlation of the freshness, the food can be stored hygienically by performing the operation control and deodorization of the cold air blowing, and also by increasing the reliability of the freshness discrimination by discriminating the freshness by a complex factor as described above.
