Description

냉장고용 제빙기의 제어방법{ICE MAKER CONTROL METHOD FOR REFRIGERATOR}ICE MAKER CONTROL METHOD FOR REFRIGERATOR}

본 발명은 냉장고용 제빙기의 제어방법에 관한 것으로, 더욱 상세하게는 겉 얼음 생산을 방지하는 냉장고용 제빙기의 제어방법에 관한 것이다.The present invention relates to a control method of a refrigerator ice maker, and more particularly, to a control method of a refrigerator ice maker that prevents the production of ice on the outside.

일반적으로, 냉장고는 냉매가 압축 - 응축 - 팽창 - 증발하는 냉동사이클을 반복함에 따라 냉장실과 냉동실 내부를 저온화시켜 음식물을 일정기간 동안 신선하게 유지시켜 주는 장치이다.In general, a refrigerator is a device that keeps food fresh for a certain period of time by lowering the temperature inside the refrigerating compartment and the freezing compartment as the refrigerant is repeatedly compressed, condensed, expanded, and evaporated.

이를 위해, 냉장고에는 냉매를 압축시키는 압축기와, 상기 압축기로부터 유입된 냉매를 외기에 의해 응축시키는 응축기와, 상기 응축기로부터 유입된 냉매를 감압시키는 팽창밸브와, 상기 팽창밸브를 통과한 냉매가 저압상태에서 증발됨에 따라 고내의 열을 흡수하는 증발기를 포함하여 구성된다.To this end, the refrigerator includes a compressor for compressing a refrigerant, a condenser for condensing the refrigerant introduced from the compressor by outside air, an expansion valve for reducing the refrigerant introduced from the condenser, and a refrigerant passing through the expansion valve at a low pressure state. It comprises an evaporator that absorbs heat in the furnace as it is evaporated in.

또한, 냉장고는 내부에 냉장실과 냉동실로 분리된 수납공간을 형성하는 본체와, 상기 본체의 전방에서 냉장실 및 냉동실을 개폐하는 도어를 구비하며, 상기 본체에는 기계실이 형성되어 상기 압축기 및 응축기가 내장된다.In addition, the refrigerator includes a main body for forming a storage space divided into a refrigerating compartment and a freezing compartment therein, and a door for opening and closing the refrigerating compartment and the freezing compartment in front of the main body, and a machine room is formed in the main body to accommodate the compressor and the condenser. .

그리고, 상기 냉동실에는 자동으로 급수, 제빙 및 이빙이 순차적으로 이루어져 얼음이 제조되는 제빙기가 설치될 수 있으며, 제조된 얼음이 일정량이 되면 보관모드로 전환된다. 상기 보관모드는 ~하는 상태를 의미한다.The freezer may be provided with an ice maker in which ice is automatically produced by sequentially supplying water, ice-making, and ice-making, and when the amount of ice is manufactured, it is switched to a storage mode. The storage mode means a state of ~.

또한, 도어에는 얼음을 외부로 취출할 수 있는 디스펜서가 장착된다.The door is also equipped with a dispenser that can take ice out.

이와 같은 제빙기는 얼음의 제조를 위한 물이 저장되는 급수 탱크와, 상기 급수 탱크에 저장된 물이 공급되어 얼음이 제조되는 아이스트레이와, 상기 아이스트레이에서 제조된 얼음이 저장되는 아이스뱅크로 구성된다. 이에 따라, 상기 아이스 트레이에서 제빙이 완료된 얼음은 이빙히터의 히팅에 의해 분리되어 아이스뱅크로 공급된다.Such an ice maker consists of a water supply tank for storing water for producing ice, an ice tray for supplying water stored in the water supply tank to manufacture ice, and an ice bank for storing ice produced from the ice tray. Accordingly, ice that has been de-iced in the ice tray is separated by heating of the ice-making heater and supplied to the ice bank.

이 경우, 종래의 제빙기는 센서에 의해 온도를 측정하여 제빙완료를 판단하였다.In this case, the conventional ice maker measures the temperature by a sensor and judged ice making completion.

그리고, 종래의 제빙기는 제빙완료 온도에 도달하면 얼음상태에 관계없이 히팅에 후속하는 이빙을 실시하였다. 즉, 겉은 얼어있고 속은 얼지않은 겉 얼음이 생산될 우려가 있었으며, 이러한 겉 얼음이 이빙 중 깨져 아이스뱅크에 보관 중인 얼음이 서로 들러붙을 수 있었다.In the conventional ice maker, when the ice making temperature is reached, ice-making is performed following the heating regardless of the ice state. In other words, there was a fear that the outer ice is frozen and the inner ice is frozen, and the outer ice is broken during the ice, and the ice stored in the ice bank may stick together.

결국, 종래의 제빙기는 센서에 의한 온도측정만으로 제빙완료를 판단함에 따라 겉 얼음이 생산되는 것을 방지하기 어려웠으며 온도측정 외에 다른 요소를 적용하여 제빙이 완료를 판단하는 제어알고리즘이 개시되지 않았다.As a result, it is difficult to prevent the production of ice on the surface of the conventional ice maker by determining the completion of ice making only by measuring the temperature by the sensor, and a control algorithm for determining the completion of ice making by applying other factors besides the temperature measurement has not been disclosed.

따라서, 제빙온도 및 제빙시간에 의해 제빙완료를 판단하는 개선된 제빙기의 제어방법이 요구되고 있다.Therefore, there is a need for an improved ice maker control method for determining ice making completion by ice making temperature and ice making time.

본 발명은 전술한 종래의 제반 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 최소제빙시간과 제빙온도를 복합적으로 판단하여 겉 얼음이 생산되는 것을 방지하는 냉장고용 제빙기의 제어방법을 제공하는 데 있다.The present invention has been made to solve the above-mentioned conventional problems, an object of the present invention to provide a control method of the ice maker for refrigerators to prevent the production of the outer ice by judging the minimum ice time and the ice making temperature complex. There is.

상기 (Ⅱ)단계의 판단결과, 제빙시간이 최소제빙완료시간을 초과했다고 판단되면 상기 (Ⅲ)단계로 이동하고, 제빙시간이 최소제빙완료시간을 초과하지 않았다고 판단되면 상기 (Ⅰ)단계로 되돌아가며,As a result of the determination in step (II), if it is determined that the ice making time exceeds the minimum ice making completion time, the process moves to step (III), and when it is determined that the ice making time does not exceed the minimum ice making completion time, the process returns to the step (I). Going,

상기 (Ⅲ)단계의 판단결과, 제빙온도가 제빙완료온도 미만이라고 판단되면 히팅과 이빙을 실시하는 (Ⅳ)단계로 이동하고, 제빙온도가 제빙완료온도 미만이 아니라고 판단되면 상기 (Ⅰ)단계로 되돌아가는 것을 특징으로 한다.As a result of the determination of step (III), if it is determined that the ice making temperature is lower than the ice making temperature, go to step (IV) to perform heating and ice-making, and if it is determined that the ice making temperature is not lower than the ice making temperature, go to step (I). Characterized by returning.

그리고, 상기 최소제빙완료시간은 45~50분인 것이 바람직하다.And, the minimum ice making time is preferably 45 ~ 50 minutes.

본 발명에 따른 냉장고용 제빙기의 제어방법에 따르면, 제빙 완료까지 최소제빙시간을 제공함과 동시에 제빙온도를 복합적으로 판단하여 겉 얼음이 생산되는 것을 방지하는 효과가 있다.According to the control method of the icemaker for a refrigerator according to the present invention, by providing a minimum ice making time until the completion of the ice making, it is effective to prevent the production of the outer ice by determining the ice making temperature complex.

또한, 센서의 이상(고장, 오작동, 측정값 오차발생 등)이 발생하여도 최소제빙시간이 주어짐에 따라 겉 얼음 생산을 억제한다.In addition, even if a sensor malfunction (failure, malfunction, measurement value error, etc.) occurs, the ice production is suppressed according to the minimum ice making time.

도 1은 본 발명에 따른 냉장고용 제빙기의 제어방법을 개략적으로 도시한 흐름도이다.1 is a flow chart schematically showing a control method of an ice maker for a refrigerator according to the present invention.

이하, 본 발명의 바람직한 실시 예를 첨부된 도면을 참조하여 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 냉장고용 제빙기의 제어방법을 개략적으로 도시한 흐름도이다.1 is a flow chart schematically showing a control method of an ice maker for a refrigerator according to the present invention.

도 1을 참고하여 제방완료를 판단하는 냉장고용 제빙기의 제어방법을 설명한다.Referring to Figure 1 will be described a control method of the icemaker for a refrigerator to determine the completion of the embankment.

먼저, 제빙운전을 시작한다(S110).First, the ice making operation starts (S110).

다음, 제빙시간이 최소제빙완료시간을 초과했는지를 판단한다(S120).Next, it is determined whether the ice making time exceeds the minimum ice making time (S120).

이때, 제빙시간이 최소제빙완료시간을 초과했다고 판단되면 다음 단계(S130)로 이동하고, 제빙시간이 최소제빙완료시간을 초과하지 않았다고 판단되면 상기 S110단계로 되돌아간다.In this case, when it is determined that the ice making time exceeds the minimum ice making time, the process moves to the next step S130, and when it is determined that the ice making time does not exceed the minimum ice making time, the process returns to step S110.

또한, 실험결과 제빙에 완료되는 시간은 통상 50분이 소요되며, 이에 따라 상기 최소제빙완료시간은 45분인 것이 바람직하다. 최소제빙완료시간이 45분인 것은 겉 얼음의 생산을 최대한 억제한 상태에서 다음 단계(S130)에서 제빙의 완료를 판단하기 위함이다.In addition, the time required for the completion of the ice making experiment usually takes 50 minutes, and thus the minimum ice making time is preferably 45 minutes. The minimum ice making time is 45 minutes in order to determine the completion of ice making in the next step (S130) while suppressing the production of the outer ice as much as possible.

한편, 최소제빙완료시간을 45분으로 특별히 한정하는 것은 아니며 냉동실의 고내온도(환경)에 따라 조정될 수 있음은 물론이다.On the other hand, the minimum ice making time is not particularly limited to 45 minutes and can be adjusted according to the internal temperature (environment) of the freezing chamber.

그리고, 아이스트레이의 제빙온도가 제빙완료온도 미만인지를 판단한다(S130).Then, it is determined whether the ice making temperature of the ice tray is less than the ice making temperature (S130).

이때, 아이스 트레이의 제빙온도가 제빙완료온도(제빙 OFF점)와 비교하여 제빙이 완료되었는지를 판단하는 것으로, 아이스 트레이의 제빙온도가 제빙완료온도(제빙 OFF점) 미만이면 제빙이 완료된 것으로 판단하여 다음 단계(S140)로 이동하고, 아이스 트레이의 제빙온도가 제빙완료온도(제빙 OFF점) 미만이 아니라고 판단되면 상기 S110단계로 되돌아간다.At this time, it is determined whether ice making is completed by comparing an ice making temperature of the ice tray with an ice making completion temperature (de-icing off point), and if ice making temperature of the ice tray is lower than an ice making completion temperature (de-icing off point), If it is determined that the ice making temperature of the ice tray is not lower than the ice making completion temperature (de-icing off point), the process returns to the step S110.

다음, 제빙이 완료됨에 따라 아이스 트레이의 히팅을 실시한다(S140).Next, as the ice making is completed, heating of the ice tray is performed (S140).

그리고, 아이스 트레이의 히팅이 완료됨에 따라 이빙을 실시한다(S150).Then, the ice is performed as the heating of the ice tray is completed (S150).

이상, 본 발명의 바람직한 실시 예에 대하여 상세히 설명하였으나, 본 발명의 기술적 범위는 전술한 실시 예에 한정되지 않고 특허청구범위에 의하여 해석되어야 할 것이다. 이때, 이 기술분야에서 통상의 지식을 습득한 자라면, 본 발명의 범위에서 벗어나지 않으면서도 많은 수정과 변형이 가능함을 고려해야 할 것이다.As mentioned above, although preferred embodiment of this invention was described in detail, the technical scope of this invention is not limited to the above-mentioned embodiment, It should be interpreted by the claim. It will be understood by those skilled in the art that many modifications and variations are possible without departing from the scope of the present invention.
