먼저 전원공금에 의해 동작이 시작되며, 이후 압축기 및 냉각용팬을 구동하여 순환통로상의 공기가 증발기를 거치면서 열교환되어 냉기로 변한 다음 덕트를 통해 냉동실 및 냉장실로 냉기가 강제공급되면서 식품을 냉동 및 냉장하는 통상의 운전작업을 실시한다(S1).First, operation is started by power supply, and then the compressor and cooling fan are driven to exchange heat in the circulation passage as it passes through the evaporator to change into cold, and then the food is frozen and refrigerated as cold air is forced to the freezer and refrigerating chamber through the duct. Normal operation is performed (S1).
이어 냉동실온도감지부(12)와 냉장실온도감지부(11)에서 냉장고 내부의 온도를 측정하는바(S2), 그 동작은 다음과 같다.Subsequently, the freezer compartment temperature detecting unit 12 and the refrigerating compartment temperature detecting unit 11 measure the temperature inside the refrigerator (S2), and the operation thereof is as follows.
내부의 온도변화에 따라 써미스터(TH1)(TH2)의 저항값이 변화하며, 이 저항값에 의해 전압(Vcc)이 변화되어 각 분압저항(R1-R2)(R3-R4)을 통해 마이컴(10)의 입력단(PI1)(PI2)으로 입력됨에 따라 마이컴(10)은 변화된 전압을 이용하여 온도를 측정하게 된다.The resistance value of the thermistor (TH1) (TH2) changes according to the internal temperature change, and the voltage (Vcc) is changed by this resistance value, and the microcomputer (10) through each voltage divider (R1-R2) (R3-R4). As input to the input terminal PI1 (PI2) of the microcomputer 10 will measure the temperature using the changed voltage.
이 측정된 온도를 적정온도와 비교하되(S3)(냉동실은 -18℃, 냉장실은 2℃) 적정온도이면(I) 단계S4로 진행하여 마이컴(10)은 마크표시구동부(13)를 출력제어한다. 이때의 제어동작은 출력단(PO1)(PO3)으로 하이레벨신호를 제공하여 인버터 (I1)(I3)를 거친 반전신호로 G색 발광다이오드(LED1)(LED3)를 점등케 한다.The measured temperature is compared with the appropriate temperature (S3) (-18 ° C. in the freezer compartment and 2 ° C. in the refrigerating chamber). If the optimum temperature is reached (I), the microcomputer 10 outputs the mark display driver 13 to the step S4. do. At this time, the control operation provides a high level signal to the output terminals PO1 and PO3 to turn on the G-color light emitting diodes LED1 and LED3 as inverted signals passing through the inverters I1 and I3.
따라서, 문자 마크 표시용 TANK(131a)와 강조 마크 표시용 마크(132a)가 G색으로 점등함에 의해 소비자는 외부에서 냉장실 및 냉동실의 상태가 적정온도임을 쉽게 인지할 수 있게 된다.Therefore, the letter mark display TANK 131a and the emphasis mark display mark 132a light up in the G color, so that the consumer can easily recognize that the state of the refrigerating compartment and the freezing compartment is at an appropriate temperature from the outside.
한편, 측정된 온도가 적정온도 이하이거나 그 이상일 경우는(J) 단계 S5로 진행하여 마크표시구동부(13)를 구동 제어한다. 즉, 출력단(PO2)(PO4)으로 하이레벨신호를 제공하여 인버터(I2)(I4)를 거친 반전신호로 R색 발광다이오드(LED2)(LED4)가 점등케 한다.On the other hand, if the measured temperature is equal to or lower than the appropriate temperature (J), the process proceeds to step S5 to control the mark display driver 13. That is, the high-level signal is provided to the output terminal PO2 (PO4) to cause the R-color light emitting diode LED2 (LED4) to light up as an inverted signal passing through the inverters I2 and I4.
따라서, 문자 마크 표시용 TANK(131a)와 강조 문자 표시용 마크(132a)가 R색으로 점등됨에 의해 소비자는 외부에서 냉장실 및 냉동실의 상태가 적정온도와 다름을 쉽게 인지할 수 있게 된다.Therefore, the character mark display TANK 131a and the emphasis character display mark 132a are lit in the R color, so that the consumer can easily recognize that the state of the refrigerator compartment and the freezer compartment is different from the appropriate temperature from the outside.
이상에서 살펴본 바와 같이 본 고안은 냉장고의 심벌마크를 색상별로 다르게 점등하여 소비자가 외부에서 냉장고의 내부상태를 쉽게 판단할 수 있게 함으로써 제품의 시각적효과와 더불어 제품의 신뢰도를 향상하는데 매우 유용한 효과가 있다.As described above, the present invention has a very useful effect to improve the reliability of the product as well as the visual effect of the product by allowing consumers to easily determine the internal state of the refrigerator by lighting the symbol mark of the refrigerator differently for each color. .
이상의 설명은 본 고안의 일실시예에 불과하며, 본 고안의 그 구성요지 범위내에서 얼마든지 변경이 가능하다.The above description is only one embodiment of the present invention, and can be changed as many within the scope of the present invention.
