Abstract

본 발명은 제빙시간을 단축할 수 있는 냉장고 자동제빙기의 제어방법에 관한 것이다.The present invention relates to a control method of an automatic refrigerator ice maker that can shorten the ice making time.

종래의 제빙시스템은 냉장고의 외부 온도가 낮아 압축기의 정지(OFF)시간이 길게되거나 도어의 개폐가 빈번하여 냉각작용이 약하게 되면, 상기 온도센서(22)를 통해 검출되는 제빙기(20)의 온도가 결빙온도(-12℃)로 내려가지 않게 되는 경우가 발생되고, 특히 제빙기(20)의 상부에 설치되어 투명한 얼음을 제빙하고자 수면이 나중에 얼도록 하여주는 열선(21)의 가열출력이 최대인 경우, 얼음을 얼리는데 시간이 많이 소요되는 얼음상자(40)에 얼음이 모이지 않아 소비자의 클레임이 제기 되기에 이르렀다.In the conventional ice making system, when the external temperature of the refrigerator is low and the compressor's OFF time is long or the door is frequently opened and closed, the cooling operation is weak, the temperature of the ice maker 20 detected by the temperature sensor 22 is increased. When the freezing temperature (-12 ℃) does not fall, especially when the heating output of the heating wire 21 is installed on top of the ice maker 20 to freeze the water later to ice the transparent ice is the maximum As the ice does not collect in the ice box 40, which takes a long time to freeze ice, consumer claims have been raised.

본 발명은 상기한 문제점을 감안하여, 냉장고의 자동제빙기에 있어서, 설정된 제빙기의 결빙시간과 결빙온도가 검출되지 않더라고 제빙기의 오도가 상기 결빙온도 보다는 높은 어떤 온도 이하이면 일정시간을 계수하되, 이때 냉각팬의 구동으로 조속히 결빙이 가능하도록하여 줌으로써, 결국 제빙시간을 단축할 수 있도록 한 냉장고 자동제빙기의 제어방법을 제공하는 것에 목적이 있다.In view of the above problems, in the automatic ice maker of the refrigerator, even if a set ice time and a freezing temperature of the ice maker are not detected, a predetermined time is counted if the degree of ice maker is below a certain temperature higher than the freezing temperature. It is an object of the present invention to provide a control method of an automatic ice maker of a refrigerator that enables the freezing of ice by driving a cooling fan as soon as possible, thereby shortening the ice making time.

따라서, 본 발명은 만빙감지스위치를 통해 얼음상자가 만빙상태가 아님이 검출되고 물감지스위치를 통해 물탱크가 있는 것이 검출되면 펌프모터를 구동시켜 급수를 진행하는 과정과, 제빙기에 부착된 온도센서를 통해 급수가 완료된 상태가 검출되면 제빙을 개시하는 과정과, 제빙이 완료되면 이빙모터등을 구동하여 이빙을 실시하는 과정을 포함하는 자동제빙기의 제어방법에 있어서, 제빙개시(급수완료)후 제빙기의 온도가 결빙온도보다는 높은 어떤 온도에 이르고, 또 그 온도를 유지하며 일정시간이 경과되면 이빙을 실행하는 과정과, 압축기의 오프온도가 검출되고 만빙감지스위치를 통해 얼음상자가 만빙이 아님이 검출되고 물감지스위치를 통해 물탱크가 있는 것이 감지되면, 압축기는 정지시키되, 냉각팬은 계속 구동하는 과정을 더 포함하여 된 것이다.Therefore, in the present invention, when the ice box is not in the ice state through the ice detection switch and the water tank is detected through the water detection switch, the pump motor is driven to supply water, and the temperature sensor is attached to the ice maker. In the control method of the automatic ice maker including the process of starting ice-making when the water supply is completed through the process and the process of driving the ice-making motor, etc., when ice-making is completed, after making ice-making (water supply completion) When the temperature reaches a certain temperature higher than the freezing temperature, and maintains the temperature and elapses a certain time, the process of performing the ice is detected, the off temperature of the compressor is detected, and the ice box is not detected by the ice detection switch. If the water tank is detected by the water detection switch, the compressor is stopped, but the cooling fan further includes the process of continuing to drive, It is.

Claims

When the ice box detects that the ice box is not in the ice state through the ice detection switch and detects the presence of the water tank through the water detection switch, the pump motor is driven to supply water and the water supply is completed through the temperature sensor attached to the ice maker. In the control method of the automatic ice maker including the process of starting ice-making when a state is detected, and performing ice-making by driving an ice motor etc. when ice-making is completed, the temperature of an ice-maker can freeze after ice-making starts (water supply completion). When the temperature reaches a certain temperature higher than the freezing temperature and maintains the temperature, and after a certain time has elapsed, the process of performing the ice is detected, and the off temperature of the compressor whose temperature is lower than that of the set freezing chamber is detected. If it is detected that the ice box is not ice and the presence of a water tank is detected by the water detection switch, the compressor will stop. Being, the cooling fan continues to drive a further method of controlling a refrigerator ice maker automatically, including the step of.
