More particularly, the present invention relates to a refrigerator compressor protection control device which can detect whether the compressor is overheated or defective and can take measures such as preventing overheating of the compressor.

일반적으로 종래에는 냉장고의 압축기를 보호할 수 있는 보호장치가 미진한 관계로, 압축기 불량에 대하여 수동적일 수 밖에 없었으며, 더우기 압축기의 불량을 미리 예방할 수도 없었다.In general, since the protection device for protecting the compressor of the refrigerator is insufficient in the related art, it has to be passive against the failure of the compressor, and furthermore, the failure of the compressor could not be prevented in advance.

따라서, 냉장고의 핵심부품인 압축기의 수명이 단축되는 결정적인 요인이 되어 왔고, 이로인한 소비자의 클레임이 증가되어 왔다.Therefore, the lifespan of the compressor, which is a key part of the refrigerator, has been a decisive factor, and consumer claims have increased.

If the outside temperature exceeds the second safety temperature of the compressor, the compressor It is characterized by having a microcomputer for performing an output to stop driving.

이하, 본 고안에 따른 냉장고 압축기 보호제어장치의 실시예를 첨부된 도면에 의거하여 보다 상세히 설명하기로 한다.Hereinafter, an embodiment of a refrigerator compressor protection control apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

Compressor temperature sensing circuit 30, an outside temperature sensing circuit 40 for sensing the outside temperature around the refrigerator to check whether the compressor is likely to overheat, a compressor driving circuit 50 for driving the compressor and , The error message display unit 60 displaying a message according to the compressor failure, and if the compressor temperature exceeds the first safety temperature in the compressor driving condition, the compressor is overheated and the compressor is stopped for a predetermined time, and the compressor is driven. If the temperature of the freezer does not drop even after a certain time has elapsed, it is determined that the compressor is defective and outputs a message accordingly. If it exceeds also consists of a microcomputer 10, which performs an output to stop driving of the compressor.

제2도는 본 고안에 의한 제어방법을 나타내는 수단으로, 이를 참조하여 본 고안의 작용 및 효과를 설명한다.2 is a means showing a control method according to the present invention, with reference to this it will be described the operation and effect of the present invention.

먼저, 전원이 인가되면, 냉장고는 통상의 운전을 수행한다.(S1단계)First, when power is applied, the refrigerator performs normal operation (step S1).

이때, 마이컴(10)은 냉동실온도감지회로(20)를 통해 입력되는 값을 검출하여 압축기가 온될 조건인가를 판단한다.(S2단계)At this time, the microcomputer 10 detects a value input through the freezer compartment temperature detecting circuit 20 to determine whether the compressor is on.

여기서, 압축기가 온될 조건이라면 압축기를 구동하기 전에 압축기 온도감지회로(30)를 통해 압축기의 온도를 검출하여 압축기의 온도가 제1안전온도 이하인가를 판단한다.(S3단계) 상기 제1안전온도는 압축기의 과열온도로서 바람직한 온도범위는 약 90°~100°이다.In this case, if the compressor is to be turned on, the compressor temperature is detected by the compressor temperature sensing circuit 30 before driving the compressor to determine whether the temperature of the compressor is equal to or less than the first safety temperature (step S3). Is the superheat temperature of the compressor, and the preferable temperature range is about 90 ° to 100 °.

상기 S3단계에서, 압축기의 온도가 제1안전온도를 초과하는 과열온도로 검출되면 일정시간을 지연(I)한 후에 다시 S3단계로 진입한다.(S4단계)In step S3, if the temperature of the compressor is detected as an overheating temperature exceeding the first safety temperature, after a predetermined time delay (I), the process returns to step S3.

그러나, 상기 S3단계에서, 압축기의 온도가 제1안전온도 이하라면 마이컴(10)은 압축기 구동회로(50)로 소정출력을 행하여 압축기를 구동시킨다.(S5단계)However, in step S3, if the temperature of the compressor is equal to or less than the first safety temperature, the microcomputer 10 generates a predetermined output to the compressor driving circuit 50 to drive the compressor.

상기 압축기가 구동된후 일정시간의 경과(II)를 체크한 후(S6단계), 상기 냉동실온도감지회로(20)를 통해 냉동실의 온도를 검출하여 냉동실의 온도가 떨어지고 있는지를 판단한다.(S7단계)After checking the elapsed time (II) of a predetermined time after the compressor is driven (step S6), the freezer compartment temperature detection circuit 20 detects the temperature of the freezer compartment and determines whether the temperature of the freezer compartment is falling. step)

여기서, 냉동실의 온도가 떨어진다면, 압축기의 상태가 정상임을 판단하고 외기온도감지회로(40)를 통해 외기온도를 검출한다.(S8단계)Here, if the temperature of the freezer compartment falls, it is determined that the state of the compressor is normal and the outside air temperature is detected through the outside air temperature sensing circuit 40. (step S8)

이때 외기온도가 압축기가 주변의 온도에 의하여 과열될 소지가 있는 제2안전온도 이하인가를 판단한다.(S9단계) 여기서, 상기 제2안전온도는 약 90°~100°이다.At this time, it is determined whether the outside temperature is equal to or less than the second safety temperature at which the compressor may be overheated by the surrounding temperature. (Step S9) Here, the second safety temperature is about 90 ° to 100 °.

상기 압축기의 온도가 제2안전온도 이하라면 통상의 루틴으로 복귀하나, 상기 압축기의 온도가 제2안전온도를 초과하는 주변온도에 의해 쉽게 과열될 소지가 있는 온도라고 판단되면 압축기 구동회로(50)로의 출력을 차단하여 압축기의 구동을 중지시킨다.(S10단계)If the temperature of the compressor is less than or equal to the second safety temperature, the routine returns to the normal routine, but if it is determined that the temperature of the compressor is easily overheated by the ambient temperature exceeding the second safety temperature, the compressor driving circuit 50 The output of the furnace is cut off to stop the operation of the compressor.

한편, 상기 S7단계에서, 냉동실의 온도가 떨어지지 않는다고 판단되면, 이는 압축기의 구동에도 불구하고 냉동실의 온도가 떨어지지 않기 때문에 명백히 압축기 불량으로 간주하고 압축기의 구동을 중지시킨다.(S11단계)On the other hand, if it is determined in step S7 that the temperature of the freezer compartment does not drop, this is obviously regarded as a defective compressor and stops the operation of the compressor because the temperature of the freezer compartment does not drop despite the drive of the compressor.

그리고, 에러메세지표시부(60)로 압축기 불량에 따른 에러 메세지가 표시되도록 소정의 출력을 한다.(S12단계)Then, the error message display unit 60 outputs a predetermined output such that an error message according to the compressor failure is displayed.

이상에서와 같이 본 고안은 압축기의 불량을 검출하고, 압축기의 불량가능성을 예방하여 냉장고 사용상의 신뢰도를 더욱 높혀 줄 뿐 아니라 압축기의 수명을 연장할 수 있는 이점이 있다.As described above, the present invention detects a failure of the compressor, prevents the failure of the compressor, and further increases the reliability of the refrigerator, and has the advantage of extending the life of the compressor.

이상의 설명은 본 고안의 일실시예에 대한 설명에 불과하며, 본 고안은 그 구성요지의 범위내에서 다양한 변경 및 개조가 가능하다.The above description is only a description of an embodiment of the present invention, and the present invention is capable of various changes and modifications within the scope of its constituent elements.
