본 발명은 냉장고의 자동제빙장치에 관한 것으로, 특히 구조가 간단하고 동작이 확실하게 한 냉장고의 자동제빙장치에 관한 것이다.The present invention relates to an automatic ice maker of a refrigerator, and more particularly, to an automatic ice maker of a refrigerator having a simple structure and a reliable operation.
근래 들어, 냉장고의 냉동실내부에 장착되어 제빙용기를 틀로 하여 물을 얼리고, 이렇게 하여 만들어진 얼음을 제빙용기에서 자동으로 이탈시켜서 저장용기에 저장하는 자동제빙 장치가 활발하게 개발되고 있다.Recently, an automatic deicing device is installed in a freezer compartment of a refrigerator to freeze water using an ice making container as a frame, and automatically removes the ice formed from the ice making container and stores the ice in the storage container.
제1도는 종래의 냉장고의 제빙장치의 일실시예에 따른 구성을 보인 개략단면도이다. 제1도에 도시한 바와 같이, 종래의 제빙장치의 일례에 따른 구성은 냉동실의 적소에 설치되는 제빙용기(1), 제빙용기(1)에 고착된 얼음을 제빙용기(1)에서 분리시키는 히이터(2), 제빙완료여부를 감지하는 온도센서(4), 제빙용기(1)에서 분리된 얼음을 제빙용기(1)의 밖으로 밀어내는 갈퀴부재(3) 및 제빙에 사용될 물을 제빙용기(1)에 공급하는 급수펌프(5)로 이루어진다. 전술한 구성을 가지는 종래의 제빙장치에서 급수펌프(5)에 의하여 제빙용기(1)에 공급된 물은 이후에 냉동실의 냉기에 의하여 얼게 된다. 이렇게 하여 얼음이 제조되는 중에 온도 센서(4)가 감지한 제빙용기(1)의 온도가 소정의 기준치이하로 되면, 제어부(미도시)는 제빙이 완료되었다고 판단하고 히이터(2)를 온시켜서 제빙용기(1)에 고착된 얼음을 분리시킨다. 이와 동시에 갈퀴부재(3)를 구동하여 얼음을 계속 밀어내므로써 제빙용기(1)에서 얼음을 이탈시키게 된다.1 is a schematic cross-sectional view showing a configuration according to an embodiment of a conventional ice maker of the refrigerator. As shown in FIG. 1, a configuration according to an example of a conventional ice making apparatus includes a heater for separating ice from the ice making container 1 and the ice sticking to the ice making container 1 installed in the freezer compartment. (2), the temperature sensor (4) for detecting the completion of ice making, the rake member (3) for pushing the ice separated from the ice making container (1) out of the ice making container (1) and the water to be used for ice making (1) It consists of a feed water pump (5) to supply. In the conventional ice making apparatus having the above-described configuration, the water supplied to the ice making container 1 by the feed water pump 5 is then frozen by cold air in the freezing chamber. In this way, if the temperature of the ice making container 1 sensed by the temperature sensor 4 while the ice is being manufactured is below a predetermined reference value, the controller (not shown) determines that ice making is completed, and turns on the heater 2 to make ice making. The ice stuck to the container 1 is separated. At the same time, by driving the rake member (3) to continue to push the ice off the ice from the ice container (1).
그러나, 전술한 구성을 가지는 종래의 제빙장치에서는 이빙과정에서 얼음을 계속 밀어야 하기 때문에 히스테리시스 동기모터와 같은 특수한 전동기가 요구되고, 나아가 히이터의 열전도특성과 이를 고정하는 방법등을 고려하여 제빙용기를 금속주물로서 제조하기 때문에 제조비용이 증가한다고 하는 문제점이 있었다.However, in the conventional ice making apparatus having the above-described configuration, a special electric motor such as a hysteresis synchronous motor is required because the ice must be continuously pushed in the ice making process, and furthermore, the ice making container is considered in consideration of the heat conduction characteristics of the heater and the method of fixing the same. There is a problem that the manufacturing cost increases because it is manufactured as a casting.
제2도는 종래의 냉장고의 제빙장치의 다른 실시예에 따른 구성을 보인 개략단면도이다. 제2도에 도시한 제빙장치에서는 온도센서(12)에서 제공된 정보에 의거하여 제빙의 완료여부를 판단하고 제빙이 완료되면, 구동박스(11)에 내장된 관련 부품들을 구동시켜 제빙용기(10)를 뒤집은 후에 비틀어서 얼음을 이탈시키게 된다. 이러한 구조로 된 제빙장치에서는 히이터를 사용하지 않으며, 나아가 비틀림을 용이하게 하기 위하여 제빙용기를 열가소성수지등의 탄성재질로 제작하게 된다.2 is a schematic cross-sectional view showing a configuration according to another embodiment of an ice maker of a conventional refrigerator. In the ice making apparatus shown in FIG. 2, the determination of whether ice making is completed based on the information provided by the temperature sensor 12, and when the ice making is completed, drive the related components embedded in the driving box 11 to make the ice making container 10. Turn over and twist to break the ice. In the ice making device having such a structure, a heater is not used, and further, an ice making container is made of an elastic material such as a thermoplastic resin in order to facilitate torsion.
그러나, 이러한 구조를 가지는 종래의 제빙장치에서는 제빙용기에서 얼음이 완전하게 이탈되지 않거나 일부분만 이탈되는 현상이 자주 발생하며, 나아가 얼음이 완전히 이탈되지 않은 상태에서 다음 제빙에 필요한 물을 공급하게 되면 이상동작이 발생하는 등의 문제점이 있었다.However, in the conventional ice making apparatus having such a structure, a phenomenon in which the ice is not completely removed or only a part of the ice is frequently removed from the ice making container, and furthermore, when water is supplied for the next ice making in a state where the ice is not completely removed, There was a problem such as an operation occurs.

이하에는 본발명의 자동제빙장치의 동작을 상세하게 설명한다.Hereinafter, the operation of the automatic ice making device of the present invention will be described in detail.
제7도는 본발명의 냉장고의 자동제빙장치의 동작을 설명하기 위한 플로우챠트이다. 제7도에 도시한 바와 같이, 전원이 인가되어 자동제빙이 수행되는 상태에서 단계(S1)에서는 이빙모터(28)를 역회전(정수평위치로의 회전을 역회전이라고 한다)시키고, 단계(S2)에서는 제빙용기(20)가 정수평위치에 도달하였는 지를 판단한다. 단계(S2)에서 제빙용기(20)가 정수평위치에 도달하지 아니한 경우에는 이빙모터(28)를 계속 동작시키고, 도달한 경우에는 단계(S3)로 진행하여 이빙모터(28)를 정지시키게 된다. 다음, 단계(S4) 내지 단계(S6)에서는 소정의 시간동안 급수펌프(26)를 동작시켜서 제빙용기(20)에 급수를 수행한다. 이렇게 하여 급수가 완료되면 이후에 냉동실의 냉기에 의하여 얼음이 만들어지게 되는데, 안계(S7)에서는 온도센서(23)가 감지한 제빙용기(20)의 온도(t)가 소정치(tI), 예를 들어 0℃에 도달하였는 지의 엽에 의거하여 제빙완료여부를 판단한다. 단계(S7)에서 제빙용기(20)의 온도가 0℃이하인 경우에는 제빙이 완료되었다고 판단하고, 단계(S8) 내지 단계(S14)에서 이빙작업을 수행하게 된다. 이를 보다 상세하게 설명하면, 단계(S8)에서는 이빙모터(28)를 정회전시켜서 제빙용기(20)의 반전을 개시한다. 단계(S9)에서는 저빙용기에 얼음이 완전히 채워져 있는 지를 판단하는데, 얼음이 완전히 채워진 경우에는 이빙모터(28)의 구동을 중지시켜서 이빙작업을 중단하게 된다. 한편, 단계(S10)에서 만빙이 감지되지 아니한 경우에는 단계(S11)에서 히이터(21)를 동작시키므로써 제빙용기(20)에 고착된 얼음을 제빙용기(20)로부터 분리시키게 된다. 다음, 단계(S12)에서는 제빙용기(20)가 이빙위치, 즉 정반전위치에 도달하였는 지를 판단하여 도달하지 아니한 경우에는 이빙모터(28)를 계속 정구동시키고, 도달한 경우에는 제빙용기(20)의 온도가 소정치에 도달하였는 지를 판단한다. 제빙용기(20)의 온도가 상승하게 되면, 얼음이 제빙용기(20)로부터 분리되게 되는데, 이 때 제빙용기(20)가 반전된 상태로 있기 때문에 얼음의 자중에 의해서 얼음이 제빙용기(20)로부터 이탈되게 된다. 따라서, 단계(S13)에서 제빙용기(20)의 온도가 소정치(ｔH)에 도달한 경우에는 얼음이 제빙용기(20)로부터 완전하게 이탈되었다고 판단하여 히이터(21)의 동작을 정지하고 다시 단계(S1)이하를 반복수행한다.7 is a flowchart for explaining the operation of the automatic ice maker of the refrigerator according to the present invention. As shown in FIG. 7, in step S1, when the power is applied and automatic deicing is performed, the moving motor 28 is reversely rotated (reverse rotation to the horizontal position is referred to as reverse rotation). In S2) it is determined whether the ice making container 20 has reached the water level position. If the ice making container 20 does not reach the horizontal position in step S2, the ice motor 28 continues to operate, and when it reaches, the process moves to step S3 to stop the ice motor 28. . Next, in steps S4 to S6, the water supply pump 26 is operated for a predetermined time to supply water to the ice making container 20. In this way, when the water supply is completed, ice is formed by the cold air of the freezer compartment. In the eye system S7, the temperature t of the ice making vessel 20 detected by the temperature sensor 23 is a predetermined value t I , For example, it is determined whether ice making is completed based on the lobe of reaching 0 ° C. When the temperature of the ice making container 20 is 0 ° C. or lower in step S7, it is determined that ice making is completed, and the ice making operation is performed in steps S8 to S14. In more detail, in step S8, the inversion of the ice maker 20 is started by rotating the ice motor 28 forward. In step S9, it is determined whether the ice is completely filled in the ice storage container. When the ice is completely filled, the icemaking operation is stopped by stopping the driving of the ice motor 28. On the other hand, when no ice is detected in step S10, by operating the heater 21 in step S11 to separate the ice stuck in the ice making container 20 from the ice making container 20. Next, in step S12, if the ice making container 20 has reached the ice making position, that is, the positive reversing position, if it does not reach, the driving motor 28 continues to be driven, and if the ice making container 20 reaches, It is determined whether the temperature reaches the predetermined value. When the temperature of the ice making container 20 rises, the ice is separated from the ice making container 20. At this time, since the ice making container 20 is inverted, the ice is caused by the weight of the ice making ice container 20. Depart from Therefore, when the temperature of the ice-making container 20 reaches the predetermined value (t H ) in step S13, it is determined that the ice is completely removed from the ice-making container 20, and stops the operation of the heater 21 again. Step S1 and below are repeated.
제8도는 본발명의 다른 실시예에 따른 제빙용기의 구조를 보인 개략단면도이다. 제8도에 도시한 바와 같이, 본발명의 다른 실시예에 따른 제빙용기(50)는 금속판재로 제작될 수도 있는데, 이 경우에도 제빙용기(50)의 저면에는 히이터(52) 및 온도센서(54)를 각각 고정하는 고정부재들(53),(55)이 제빙용기(50)와 일체로 성형될 수 있다. 도면에서, 미설명부호51은 제빙용기(50)와 함께 삽입사출 성형되는 플라스틱제 지지부를 나타낸다.8 is a schematic cross-sectional view showing the structure of an ice making container according to another embodiment of the present invention. As shown in FIG. 8, the ice making container 50 according to another embodiment of the present invention may be made of a metal plate, and in this case, the heater 52 and the temperature sensor (at the bottom of the ice making container 50) Fixing members 53 and 55 fixing the 54 may be integrally formed with the ice making container 50. In the figure, reference numeral 51 denotes a plastic support part which is injection molded together with the ice making container 50.
이상에서 설명한 바와 같은 본발명의 냉장고의 자동제빙장치에 따르면, 특수한 전동기나 금속주물로 된 제빙용기를 사용하지 않기 때문에 제작비용이 절감되는 효과가 있고, 나아가 제빙용기를 비틀지 않고도 이빙작업이 수행되기 때문에 적은 토오크의 전동기를 사용할 수 있는 이외에 적은 강도를 가지는 제빙용기를 사용할 수 있는 잇점이 있다.According to the automatic de-icing device of the refrigerator of the present invention as described above, the manufacturing cost is reduced because no special motor or metal casting ice making container is used, and the ice-making operation is performed without twisting the ice making container. Therefore, there is an advantage in that an ice making container having a low strength can be used in addition to a motor having a low torque.
