상기와 같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.

먼저, 냉장고(1)가 구동하고 있는 상태에서 냉장고의 냉장실 또는 냉동실도어(2)(3)를 열게되면 제3도의 (b)(c) 및 제4도에 도시된 바와같이 냉동.냉장실도어스위치(22)(23)는 온접속되면서 제3도에 도시한 바와같이 냉동.냉장실고내등(20)(21)을 각각 구동시켜주게 되고, 이어서 냉동.냉장실도어(2)(3)를 닫게되면 제3도에 도시한 바와같이 냉동.냉장실도어스위치(22)(23)는 오프접속되게되어 냉동.냉장실고내등(20)(21)은 오프되지만 팬모타(16)에는 전류가 인가되어 팬모타(16)가 구동하면 냉동.냉장을 하게된다.First, when the refrigerator 1 or the freezer door 2 or 3 of the refrigerator is opened while the refrigerator 1 is being driven, the freezer / refrigerator door switch as shown in (b) (c) and 4 of FIG. (22) (23) are connected to each other to drive the freezer and refrigerator compartment interior lights (20, 21) as shown in FIG. 3, and then close the freezer and refrigerator compartment doors (2) and (3). As shown in FIG. 3, the freezer and refrigerator door switches 22 and 23 are turned off so that the freezer and refrigerator compartment lamps 20 and 21 are turned off, but the fan motor 16 is supplied with a current and the fan motor 16 is turned off. ) Is driven to freeze and refrigerate.

상기와 같이 냉동.냉장실도어(2)(3)를 닫게되는 상태에서 상기 냉장고의 구동을 제어하게되는 제어부(도시되지 않음)에서는 먼저 냉동.냉장실도어개폐판단단계(50)로 가서 냉동.냉장실도어(2)(3)가 열렸다 닫았는가를 판단하게되고, 이때 닫혀져 있으면 제어부에서는 타이머 작동단계(51)로 가서 센서용타이머(13)에 전원단(AC)으로부터 전류를 인가하여 센서용타이머(13)을 작동시키면서 팬모타(14)에 전류를 인가하여 냉동.냉장기능을 수행시키고 시간적산단계(52)로 가서 상기 센서용타이머(13)의 작동시간을 적산하게 한다.As described above, the control unit (not shown) that controls the operation of the refrigerator in the state of closing the freezing / refrigeration doors 2 and 3 first goes to the freezing / freezing compartment door opening / closing judging step 50 and freezing / freezing compartment doors. (2) It is determined whether (3) is open and closed, and if it is closed at this time, the control unit goes to the timer operation step 51 and applies a current from the power supply terminal AC to the sensor timer 13 to output the sensor timer 13 While operating the fan motor 14, the electric current is applied to perform the freezing / refrigerating function and go to the time integration step 52 to integrate the operating time of the sensor timer 13.

이와같이 작동시간을 적산한 상태에서 제어부에서는 도어재개폐여부판단단계(53)로 가서 상기 센서용타이머(13)가 작동하는 동안 도어가 다시 개폐되지 않은 것으로 판단되면 온도감지용 센서동작단계(54)로 가서 상기 센서용타이머(13)를 온도감지용센서(14)방향으로 센서용 타이머(13)단자를 작동시켜 상기 온도감지용센서(14)로 전류가 인가되도록 하면서 온도를 감지하게 한다.In this state in which the operation time is accumulated, the control unit goes to the door reopening or closing judging step 53, and if it is determined that the door is not opened or closed again while the sensor timer 13 is operating, the sensor operation step 54 for detecting temperature The sensor timer 13 is moved to the temperature sensing sensor 14 toward the sensor 13 to operate the terminal 13 to sense the temperature while allowing a current to be applied to the temperature sensing sensor 14.

이때 온도감지용센서(14)의 작동은 제2도에 도시한 바와같이 온도센서(7)로부터 작동을 시작하여 온도감지를 하되, 온도감지판단단계(55)로 가서 상기 센서용 타이머(13)에 의하여 소정시간간격으로 상기 온도감지용센서(14)의 온도센서(7)(8)(9)(10)를 작동시켜 가면서 온도감지저장반복완료판단단계(56)로 가서 제2도 및 제4도에 도시한 바와같이 냉장.냉동실도어(2)(3)의 가스켓부분과 캐비넷(1)사이의 열전달량을 소정시간간격으로 반복 감지하되 도어개폐여부를 판단할 수 있는 충분한 데이타를 감지하게 된다.At this time, the operation of the temperature sensing sensor 14 starts the operation from the temperature sensor 7 as shown in FIG. 2 to perform temperature sensing, but goes to the temperature sensing judging step 55 and the sensor timer 13 By operating the temperature sensor (7) (8) (9) (10) of the temperature sensor 14 for a predetermined time interval by going to the temperature sensing storage repeated determination step 56 As shown in Fig. 4, the heat transfer between the gasket portion and the cabinet 1 of the refrigerating and freezing chamber doors (2) and (3) is repeatedly detected at a predetermined time interval to detect sufficient data to determine whether the door is opened or closed. do.

상기와 같이 도어개폐여부를 판단할 수 있을 정도로 감지된 온도는 감지된 온도연산단계(57)로 가서 감지된 온도의 변화량이 심한가를 연산하게 되고, 상기 온도편차판단단계(58)로 가서 감지된 온도의 편차 즉, 온도변화량이 심한가 또는 상기 온도센서(7)(8)(9)(10)에서 감지된 온도의 횟수에 따른 온도평균치변화가 심한가를 판단하게된다.As described above, the temperature sensed enough to determine whether the door is opened or closed is calculated by going to the detected temperature calculation step 57 and calculating whether the detected change in temperature is severe. It is determined whether the variation in temperature, that is, the temperature change amount is severe or the temperature average value change is severe according to the number of temperatures detected by the temperature sensors (7) (8) (9) (10).

따라서 상기 감지된 온도편차가 소정온도이상이 되면, 상기 제어부에서는 냉동.냉장실도어(2)(3)가 미세하게 열려있는 것으로 판단하고 도어미세열림경보단계(59)로 가서 제3도, 제4도에 도시한 바와같이 알람(15)에 전류를 흘려주는 반면에 팬모타(16)의 전류를 차단하면서 도어가 미세하게 열려있음을 경보해주게 되고, 상기 감지된 온도편차가 소정온도이하이면 도어가 닫혀있음을 판단하여 센서용타이머(13)의 팬모터(14)에 전류를 인가해주는 방향으로 스위치를 작동시켜 냉동.냉장단계(60)으로 가서 정상, 냉동, 냉장구동을 하게 되는 것이다.Therefore, when the detected temperature deviation is more than a predetermined temperature, the control unit determines that the freezing and refrigerating chamber doors (2) and (3) are finely opened and goes to the door fine opening alarm step (59). As shown in the figure, while flowing a current to the alarm 15, while blocking the current of the fan motor 16 alerts that the door is finely opened, if the detected temperature deviation is less than a predetermined temperature the door is It is determined that it is closed by operating the switch in the direction to apply a current to the fan motor 14 of the sensor timer 13 to go to the freezing and refrigerating step (60) to perform normal, freezing, refrigeration drive.

이상에서 설명한 바와같이 본 발명은 냉장고의 도어개폐식 도어가 미세하게 열려져 있을 경우, 도어부의 온도변화량을 소정간격으로 감지하여 감지된 온도변화편차로 도어의 미세열림상태를 판단하여 경보를 하도록 함으로써, 간혹 냉장.냉동실도어의 미세열림으로 인하여 야기되는 냉동.냉장실의 냉동.냉장저하로 냉동식품 및 냉장식품의 변질되는 현상을 방지해 줄 수 있는 효과를 제공하게 되는 것이다.As described above, in the present invention, when the door opening / closing door of the refrigerator is opened finely, the temperature change amount of the door part is detected at a predetermined interval, and the alarm is determined by judging the minute opening state of the door by the detected temperature change deviation. It is to provide the effect that can prevent the deterioration of frozen foods and refrigerated foods due to the freezing and lowering of the freezing and refrigerating chamber caused by the micro-opening of the refrigeration and freezing chamber door.
