본 발명은 냉장고의 자동온도조절장치에 관한 것으로, 특히 냉장고의 냉동, 냉장실에 저장되는 식품의 양에 따라 냉동실 및 냉장실의 온도가 자동으로 조절되도록 한 냉장고의 자동온도조절장치에 관한 것이다.The present invention relates to a thermostat of a refrigerator, and more particularly, to a thermostat of a refrigerator for automatically controlling the temperature of the freezer compartment and the refrigerating chamber according to the amount of food stored in the freezer and refrigerator compartment of the refrigerator.

일반적으로 냉장고에는 냉동실 및 냉장고의 온도를 크게 강, 중, 약으로 조절할 수 있는 온도조절기가 부착되어 있어 이 온도조절기로 냉동실 및 냉장실의 온도를 저장된 식품의 양과 계절에 따라 강, 중, 약으로 조절하면서 식품을 적절한 온도로 저장할 수 있도록 되어 있다.In general, the refrigerator is equipped with a temperature controller that can control the temperature of the freezer and the refrigerator to be strong, medium, or weak, and the temperature controller controls the temperature of the freezer and the freezer to strong, medium, or weak depending on the amount of food stored and the season. The food can be stored at the proper temperature.

그러나, 상기와 같은 온도조절기의 경우 사용자가 저장되는 식품의 양과 계절에 따라 그때 그때마다 고내온도를 선택해야 하는 번거로움이 있는 관계로, 사용자의 대부분이 온도조절기를 한번 적절한 온도로 설정하여 놓고 다시 변경하지 않은 채 그대로 사용하게 된다.However, in the case of the temperature controller as described above, the user has to select the internal temperature at that time according to the amount and season of food stored, so most of the users set the temperature controller to an appropriate temperature once and then again. It will be used as is without change.

따라서 저장되는 식품의 양이 많거나 하절기의 경우 또는 저장되는 식품의 양이 적거나 동절기의 경우에는 온도조절기로 설정한 온도보다 고내온도가 높아지거나 낮아지게 되어 고내에 저장된 식품을 효과적으로 냉동 또는 냉장시키지 못하여 식품이 변질되게 되며, 또한 컴프레서의 구동이 효율적으로 수행되지 못하여 불필요한 전력을 소비하게 되는 문제점이 있었다.Therefore, when the amount of food stored is high, or in summer, or when the amount of food stored is small, or in winter, the internal temperature is higher or lower than the temperature set by the temperature controller, so that the food stored in the refrigerator is not effectively frozen or refrigerated. There is a problem in that the food is deteriorated, and the drive of the compressor is not efficiently performed to consume unnecessary power.

이에 본 발명은 냉장고의 냉동실 및 냉장실에 저장된 양에 따라 고내온도가 적절한 온도로 자동조절되도록 함으로써 고내온도 변화에 의한 저장식품의 변질을 방지함과 동시에 저장식품과 양과 계절에 따라 고내온도를 일일이 조작해야하는 번거로움을 해소할 수 있도록 된 냉장고의 자동온도조절장치를 제공하는데 그 목적이 있다.In the present invention, the internal temperature is automatically adjusted to an appropriate temperature according to the amount stored in the freezer and the refrigerating chamber of the refrigerator, thereby preventing the deterioration of the stored food due to the change in the internal temperature, and simultaneously operating the stored internal temperature according to the stored food and the quantity and season. It is an object of the present invention to provide a thermostat of a refrigerator that can eliminate the hassle.

본 발명의 다른 목적은 냉동실 및 냉장실에 저장된 식품의 양에 따라 고내온도를 자동조절함으로써 컴프레서의 불필요한 구동을 방지하여 전력소비를 줄일 수 있도록 된 냉장고의 자동온도조절장치를 제공하는 것이다.Another object of the present invention is to provide an automatic thermostat of a refrigerator which can reduce power consumption by preventing unnecessary driving of the compressor by automatically adjusting the internal temperature according to the amount of food stored in the freezer compartment and the refrigerator compartment.

상기의 목적을 실현시키기 위하여 본 발명에 따른 냉장고의 자동온도조절장치는 컴프레서를 포함하는 각 부하의 구동을 제어하는 부하제어부 및 고내온도를 감지하는 온도감지부를 구비하여 고내온도를 일정온도로 무에 따라 고내식품량을 감지하는 식품량감지부, 고내식품량에 따라 고내온도를 가변시키도록 상기 부하제어부를 제어하는 마이콤을 구비한 것을 특징으로 한다.In order to achieve the above object, the automatic temperature control apparatus of the refrigerator according to the present invention includes a load control unit for controlling the driving of each load including a compressor and a temperature sensing unit for detecting the internal temperature of the refrigerator. According to the food quantity detecting unit for detecting the food in the high, according to the high food in the food, characterized in that it comprises a micom for controlling the load control unit to vary the temperature in the high.

또한, 본 발명에 따른 냉장고의 자동온도조절장치에 있어서, 식품량 감지부는 적외선발광부가 냉장고의 일측벽에 수직으로 다수개 배치되고, 수광부가 상기 적외선발광부와 대향하는 위치의 다른 측벽에 수직으로 다수개 배치된 것을 특징으로 한다.In addition, in the automatic temperature control apparatus of the refrigerator according to the present invention, the food quantity sensing unit is disposed a plurality of infrared light emitting unit vertically on one side wall of the refrigerator, the light receiving unit is perpendicular to the other side wall of the position facing the infrared light emitting unit It is characterized in that a plurality arranged.

이하 첨부된 도면에 의거하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도면중 미설명 부호인 라은 제빙닥트이고, 마는 얼음그릇이다.In the drawings, the reference numeral Ra is an ice making duct, and a rolling ice bowl.

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

먼저, 냉장고(가)에 전원을 인가시키면 냉장고(가)의 온도감지부(1), 도어감지부(2), 제빙감지부(3) 및 식품량감지부(11)가 구동상태로 들어가게 되고, 이어서 마이콤(4)에서 상기 각 감지부(1),(2),(3)에서 감지된 상태에 따라 미리 프로그래밍된 상태로 부하제어부(5)를 제어하여 컴프레서(6), 히터(7), 팬 모터(8), 고내등(9)의 구동을 제어하게 된다.First, when power is supplied to the refrigerator, the temperature sensor 1, the door sensor 2, the ice making sensor 3, and the food quantity sensor 11 of the refrigerator enter the driving state. Subsequently, the load control unit 5 is controlled by the microcomputer 4 in a pre-programmed state according to the states detected by the detection units 1, 2, and 3, and the compressor 6 and the heater 7 The driving of the fan motor 8 and the lamp 9 is controlled.

이어서 냉장고(가)의 도어를 열고 냉동실(나)와 냉장실(다)에 식품을 넣게 되면 마이콤(4)에서는 상기 식품량감지부(11)의 발광부와 수광부를 가진 센서를 통하여 식품량을 감지하고, 감지된 식품량에 따라 미리 프로그램된 상태로 각 부하제어부(5)를 제어하여 컴프레서의 구동을 강, 중, 약으로 제어하여 식품의 양에 따라 고내온도를 조절하게 되는데 이 과정을 제 3 도에 도시한 플로우차트를 참조하여 설명하면 다음과 같다.Subsequently, when the refrigerator is opened and the food is put into the freezer compartment (C) and the refrigerating compartment (C), the microcomputer 4 detects the amount of food through a sensor having a light emitting unit and a light receiving unit of the food quantity detecting unit 11. In addition, by controlling the load control unit 5 in a pre-programmed state according to the amount of food detected, the driving of the compressor is controlled to be strong, medium, or weak to adjust the internal temperature according to the amount of food. The following description will be made with reference to the flowchart shown in FIG.

마이콤(4)에서는 먼저 제빙감지부(3)를 통하여 제빙신호가 있는가를 확인하고, 제빙신호가 있으면 소정의 제빙시간동안 컴프레서(6)을 연속적으로 구동시켜 제빙운전을 하게 된다. 소정의 제빙시간이 경과되면 마이콤(4)에서는 컴프레서(6)의 연속적인 구동을 중지하고, 냉동실의 온도감지부(1)에 의해 냉동실의 온도가 '중간단계'에 대응하여 설정된 온도이상인 경우에는 상기 설정온도까지 고내온도가 낮아지도록 컴프레서(6)를 구동시키게 된다.The microcomputer 4 first checks whether there is an ice making signal through the ice making detector 3, and if there is an ice making signal, the compressor 6 is continuously driven for a predetermined ice making time. When the predetermined ice making time has elapsed, the microcomputer 4 stops the continuous driving of the compressor 6, and when the temperature of the freezer compartment is higher than the temperature set in response to the 'intermediate stage' by the temperature sensing unit 1 of the freezer compartment. The compressor 6 is driven to lower the internal temperature up to the set temperature.

그러나, 제빙신호가 없으면, 마이콤(4)에서는 식품량감지부(11)를 통해서 수광부로 수신되는 신호의 유무를 감지하여 저장된 식품의 양을 판단하게 된다. 이때 냉동실(나)의 식품이 적은 것으로 판단되는 경우에는, 상대적으로 식품에서 흡수되는 냉동실의 냉기가 적으므로 냉동실(나)의 고내온도가 낮아지게 된다. 따라서, 마이콤(4)에서는 부하제어부(5)를 제어하여 냉동실 온도가 '약단계'에 상응하는 온도가 될때까지 컴프레서(6)를 구동시키고, 저장된 식품이 많을 경우에는 식품과의 열교환에 의하여 냉동실(나)의 고내온도가 높아지게 되므로 마이콤(4)에서는 부하구동부(5)를 제어하여 고내온도가 '중간단계'에 상응하는 온도까지 낮아지게 되면 컴프레서(6)의 구동을 정지시키게 된다.However, if there is no ice making signal, the microcomputer 4 detects the presence or absence of a signal received by the light receiving unit through the food quantity detecting unit 11 to determine the amount of stored food. At this time, when it is determined that the food in the freezer compartment (b) is less, the cold temperature of the freezer compartment is relatively less absorbed by the food, so that the internal temperature of the freezer compartment (b) is lowered. Therefore, the microcomputer 4 controls the load control unit 5 to drive the compressor 6 until the freezer temperature reaches a temperature corresponding to the 'weak step', and when there are many stored foods, the freezer compartment by heat exchange with the food. Since the internal temperature of (B) is increased, the microcomputer 4 controls the load driving unit 5 to stop the operation of the compressor 6 when the internal temperature is lowered to a temperature corresponding to the 'middle stage'.

이어서 상기 마이콤(4)에서는 냉장실에 저장되는 식품의 양을 식품량감지부(11)의 센서를 통해서 감지하며, 식품량감지부(11)의 수광부로 수신되는 수신신호의 유무를 판단하여 냉장고(다)에 저장식품이 많은가를 판단하게 된다. 이때, 저장된 식품이 많으면 상기 냉장실(다)의 냉기가 식품과의 열교환에 의하여 다량 흡수되게 되므로 그 만큼 냉장고(다)의 온도가 상승하게 된다.Subsequently, the microcomputer 4 senses the amount of food stored in the refrigerating chamber through the sensor of the food quantity detecting unit 11, and determines whether there is a reception signal received by the light receiving unit of the food quantity detecting unit 11 to determine the refrigerator ( C) It is judged whether there are a lot of stored foods. At this time, if there is a lot of food stored, the cold air in the refrigerating compartment (C) is absorbed in large amounts by heat exchange with the food, and thus the temperature of the refrigerator (C) increases.

따라서, 마이콤(4)에서는 냉장실(나)내에 저장된 식품량에 따른 냉장실(나)내의 온도변화에 의거하여 부하제어부(5)를 제어하여 컴프레서(6)를 구동시키고, 냉장실(나)의 온도가 '강단계'에 해당하는 온도까지 낮아졌으며 부하제어부(5)를 제어하여 컴프레서(6)의 구동을 오프시키게 된다. 반면, 식품량감지부(11)의 감지결과에 의하여 냉장실(다)내에 저장된 식품의 양이 적은 것으로 판단되면, 부하제어부(5)를 제어하여 컴프레서(6)를 구동시킨 뒤 냉장실(나)의 온도가 '중간단계'에 상응하는 온도까지 낮아졌으면 부하제어부(5)를 제어하여 컴프레서(6)의 구동을 오프시키게 된다.Therefore, in the microcomputer 4, the compressor 6 is driven by controlling the load control unit 5 based on the temperature change in the refrigerating chamber (b) according to the amount of food stored in the refrigerating chamber (b), and the temperature of the refrigerating chamber (b) is increased. The temperature is lowered to a temperature corresponding to the 'strong stage' and the load control unit 5 is controlled to turn off the compressor 6. On the other hand, if it is determined that the amount of food stored in the refrigerating compartment (C) is small based on the detection result of the food quantity detecting unit 11, the load control unit 5 is driven to drive the compressor 6 and then the When the temperature is lowered to a temperature corresponding to the 'middle stage', the load control unit 5 is controlled to turn off the compressor 6.

한편, 상기 냉동실(나)의 냉동식품이 적은 경우 식품량감지부(11)에서는 이를 감지하고 마이콤(4)에서는 컴프레서(6)를 고내온도가 '약단계'에 상응하는 온도가 될때까지 구동시키게 되므로 절전운전을 하게 된다.On the other hand, when there is little frozen food in the freezer (b), the food quantity detecting unit 11 detects this, and in the microcomputer 4, the compressor 6 is driven until the internal temperature reaches a temperature corresponding to the 'about step'. Therefore, it saves power.

이상에서 설명한 바와 같이 본 발명은 냉장실 및 냉동실에 저장된 식품의 량을 식품량감지부를 통하여 감지하여 식품량에 따라 고내온도가 강, 중, 약단계에 상응하는 온도로 유지될 수 있도록 부하제어부를 통하여 컴프레서의 구동을 오프시킴으로써 냉장고내의 온도를 자동조절할 수 있게 되어 사용자가 식품량 및 계절에 따라 냉장고내의 온도를 수동적으로 조절해야 하는 번거로움을 해소할 수 있는 이점이 있다. 또한, 컴프레서의 부적절한 구동으로 인한 식품의 변질 및 전력낭비등의 문제점을 해결할 수 있게 된다.As described above, the present invention detects the amount of food stored in the refrigerating compartment and the freezing chamber through the food quantity detecting unit, so that the internal temperature can be maintained at a temperature corresponding to the strong, medium, or weak phase according to the amount of food. By turning off the compressor, it is possible to automatically adjust the temperature in the refrigerator, thereby eliminating the need for the user to manually adjust the temperature in the refrigerator according to the amount of food and the season. In addition, it is possible to solve problems such as food deterioration and power consumption due to improper operation of the compressor.
