일반적으로, 자동 제빙기는 제빙이 완료되면 통상적으로 다음에 이빙 동작을 실시한다. 즉, 수평상태에 있는 제빙용기를 모터에 의해 회전시켜 이빙한다. 예를들면 정방향으로 회전시켜 하부 방향으로 반전시키고, 또 하부 방향이 되기전에 제빙용기를 비틀어 얼음이 제빙용기에서 떼어지기 쉽게 한다. 이와같은 반전 및 비틀기에 의해 제빙용기내의 얼음이 이빙하여 아래쪽에 배치된 저장용기로 낙하되어 저장되는 것으로, 이와 같은 종래의 기술을 첨부한 도면을 참조하여 설명하면 다음과 같다.In general, automatic ice makers typically perform the next ice-making operation when ice making is completed. That is, the ice making machine in the horizontal state is rotated by the motor and iced. For example, it rotates in the forward direction, reverses the downward direction, and twists the ice maker before reaching the downward direction, so that the ice is easily removed from the ice maker. By the reversal and twisting as described above, the ice in the ice making container is dropped and stored in the storage container disposed under the ice, which is described below with reference to the accompanying drawings.

도 1, 도 2는 종래의 자동 제빙기의 구성을 보인 예시도로서, 이에 도시한 바와 같이 냉장고 본체(7)의 내부에는 외부의 급수원과 배관(9)으로 연결되어 배관(9)을 통해 급수된 물을 필터링하기 위한 필터부(6)와; 상기 필터부(6)에 의해서 정수된 물의 급수로를 선택적으로 차단 및 개방시키는 급수 밸브(10)와; 상기 급수 밸브(10)에서 배관(9)을 통해 급수된 물을 제빙시키기 위한 제빙기(2)와; 상기 급수 밸브(10)에서 배관(9)을 통해 급수된 물을 일정량 저장하기 위한 물탱크(11)와; 상기 제빙기(2)에서 만들어진 얼음 또는 물탱크(11)로 부터 배관(9)을 통해 공급된 물을 사용자의 누름 조작에 의해서 선택적으로 컵에 받아 마실수 있는 디스펜스(13)로 구성된다.1 and 2 is an exemplary view showing a configuration of a conventional automatic ice maker, as shown in the interior of the refrigerator body 7 is connected to an external water supply source and the pipe (9) to supply water through the pipe (9) A filter unit 6 for filtering the water; A water supply valve 10 for selectively blocking and opening a water supply passage of water purified by the filter unit 6; An ice maker (2) for ice-making water supplied from the water supply valve (10) through the pipe (9); A water tank 11 for storing a predetermined amount of water supplied through the pipe 9 from the water supply valve 10; It is composed of a dispensing 13 that can receive the water supplied through the pipe (9) from the ice or water tank 11 made in the ice maker (2) selectively receive the cup by the user's pressing operation.

그리고, 상기 제빙기(2)는 급수된 물을 받아 냉동실(1) 내부의 냉기로 제빙 행정을 수행하는 제빙용기(3)와; 상기 제빙용기(3)에서 만들어진 얼음을 열로 제빙 용기(3)로 부터 분리시키기 위해 제빙용기(3)의 바닥면에 장착되는 히터(도시는생략함)와; 상기 히터에 의해서 제빙용기(3)와 분리된 얼음을 취출시키기 위해 제빙 용기(3)의 상부측에 회전가능하게설치되는 취출기(4)와; 상기 취출기(4)의 회전에 의해서 취출된 얼음을 제빙용기(3)의 하부측에서 받아 일정량 저장하기위한 저장용기(5)와; 상기 저장용기(5)에 담겨진 얼음을 상기 디스펜스부(13) 측으로 이송시키기 위한 이송 수단으로구성된다.The ice maker 2 includes an ice maker 3 which receives the water supplied and performs an ice making stroke with cold inside the freezing chamber 1; A heater (not shown) mounted on the bottom surface of the ice making container (3) to separate the ice produced in the ice making container (3) from the ice making container (3) by heat; A blower (4) rotatably installed on an upper side of the ice making container (3) to take out the ice separated from the ice making container (3) by the heater; A storage container (5) for receiving a portion of the ice taken out by the rotation of the take-out (4) at the lower side of the ice making container (3) and storing a predetermined amount; It consists of a conveying means for conveying the ice contained in the storage container (5) toward the dispensing portion (13).

즉, 상기한 바와 같은 종래의 자동 제빙기에 있어서, 이빙제어방법은 도 3에 도시된 바와 같이 제빙종료후 히터를 구동하고 제빙용기(3)의 온도를 감지하여 히터의 열로 제빙용기(3)에서 만들어진 얼음을 제빙용기(3)로부터 분리시키기 위한 목표온도에 도달했는지를 판단하여 상기 목표온도에 도달하면 히터를 정지시키고 이빙제어를 실시하는 제1 과정(S31~S35)과; 상기 제빙용기(3)로부터 얼음을 분리시키기 위한 목표온도에 도달하지 않으면 히터를 정지시키고 히터불량을 표시하는 제2 과정(S36~S38)을 수행하도록 이루어진 것으로, 이와 같은 종래의 기술을 설명하면 다음과 같다.That is, in the conventional automatic ice maker as described above, the ice-making control method is to drive the heater after the end of the ice as shown in Figure 3 and to sense the temperature of the ice making container (3) in the ice making container (3) by the heat of the heater Determining whether the ice has reached a target temperature for separating the ice from the ice-making container 3, and stopping the heater and performing the ice control when the target temperature is reached; If it does not reach the target temperature for separating the ice from the ice-making container (3) is made to perform the second process (S36 ~ S38) to stop the heater and display the heater defects, such a conventional technique Same as

먼저, 제빙기(2)는 필터부(6)에 의해서 정수된 물의 급수로를 선택적으로 차단 및 개방시키는 급수 밸브에서 배관(9)을 통해 급수된 물을 제빙시킨다.First, the ice maker 2 ices the water supplied through the pipe 9 in a water supply valve that selectively blocks and opens the water supply path of the water purified by the filter unit 6.

이에, 상기 제빙기(2)는 얼음을 만든후 히터를 구동시켜 제빙용기의 온도를 감지하여 히터의 열로 제빙용기(3)에 만들어진 얼음을 제빙용기(3)로부터 분리시킨다(S31, S32).Thus, the ice maker 2 drives the heater after making the ice, senses the temperature of the ice maker container, and separates the ice made in the ice maker 3 from the ice maker 3 by the heat of the heater (S31, S32).

이때, 상기 제빙용기(3)로부터 얼음을 분리시키기 위한 목표온도에 도달하면 히터를 정지시킨후 180°회전시킨후 저장용기(5)에 얼음을 이빙시킨다(S33~S35).At this time, when reaching the target temperature for separating the ice from the ice making container (3), the heater is stopped and rotated 180 ° and then iced to the storage container (5) (S33 to S35).

그러나, 상기 제빙용기(3)로부터 얼음을 분리시키기 위한 목표온도에 도달하지 않게 되면 히터구동 시간이 일정시간 경과했는지를 판단하여 그 판단결과, 히터구동 시간이 일정시간 경과하면 그 히터를 정지시키고 히터불량상태임을 디스플레이창에 디스플레이하고, 상기 판단결과, 히터구동 시간이 일정시간 경과하지 않았다면 상기 히터를 계속해서 구동시킨다(S36~S38).However, when the target temperature for separating the ice from the ice making container 3 does not reach, it is determined whether the heater driving time has elapsed for a predetermined time. As a result of the determination, the heater is stopped when the heater driving time has elapsed for a certain time. If it is determined that the defective state on the display window, and as a result of the determination that the heater driving time has not elapsed for a predetermined time continues to drive the heater (S36 ~ S38).

그러나, 상기와 같이 동작하는 종래 기술은 냉동실이 많이 차가울 경우 히터 발열을 하여도 센서온도가 일정 온도에 도달하기 어려운 경우가 발생할 수 있다.However, the prior art operating as described above may occur when the temperature of the sensor is difficult to reach a predetermined temperature even if the freezer compartment is very cold, even if the heater generates heat.

이러한 경우에는 히터의 불량이 아님에도 불구하고 히터의 불량으로 오판하여 제빙기가 동작을 하지 않을수 있는 문제점이 있었다.In such a case, there is a problem that the ice maker may not operate due to a mistake in the heater even though the heater is not defective.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 창안한 것으로, 이빙제어전에 히터의 동작시간과 센서온도를 동시에 판단하여 두가지 조건중에 한가지 조건이 만족되면 이빙제어를 실시하고, 만약 히터의 불량으로 이빙이 제대로되지 않을경우(얼음을 이젝터가 제대로 이빙 시키지 못함) 이것을 제빙기가 감지(홀센서등을 이용)하여 이빙 제어를 정지시키고 히터의 불량을 판단할 수 있도록 한 자동 제빙기의 이빙제어방법을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, and before the ice control, the operation time of the heater and the sensor temperature are simultaneously determined, and if one of the two conditions is satisfied, the ice removal control is performed. If the ice is not working properly (the ice ejector does not move properly), the ice maker detects the ice (using a hall sensor, etc.) to stop the ice control and provide the ice control method of the automatic ice maker. Has its purpose.

도 4는 본 발명 자동 제빙기의 이빙제어방법을 보인 흐름도로서, 이에 도시된 바와 같이 제빙 행정을 진행후 히터를 구동하고, 감지된 제빙용기의 온도로 상기 히터를 구동시켜 그 히터의 열로 제빙 용기내의 얼음을 제빙용기로부터 분리시키는 단계(S41)와; 상기 제빙용기로부터 얼음을 분리시키기 위한 목표온도에 도달했는지 히터 구동시간이 일정시간경과했는지 판단하여 상기 목표온도에 도달하거나 히터 구동시간이 일정시간경과하면 히터를 정지시키고 이젝터를 구동하여 이빙제어를 실시하는 단계(S42~S46)와; 홀센서를 통해 상기 이젝터가 목표행정거리에 도달하여 이빙동작을 완료했는지 판단하여 상기 이젝터가 목표행정거리에 도달하면 이빙제어를 정지시키는 단계(S47~S48)와; 상기 이젝터가 목표행정거리에 도달하지 않았다면 그 이젝터의 구동시간이 소정시간이상 경과했는지 체크하여 그 소정시간 경과하면 상기 이젝터를 정지시키고 히터불량임을 알리는 단계(S49~S51)로 이루어진 것으로, 이와 같은 본 발명의 동작 및 작용을 상세히 설명하면 다음과 같다.4 is a flowchart illustrating a method of controlling the ice of the automatic ice maker according to the present invention. As shown in FIG. 4, the heater is driven after the ice making process is performed, and the heater is driven at the detected temperature of the ice maker to heat the heater in the ice maker. Separating ice from the ice making container (S41); It is determined whether the target temperature for separating ice from the ice making container is reached or the heater driving time has elapsed for a predetermined time. When the target temperature is reached or the heater driving time has elapsed for a predetermined time, the heater is stopped and the ejector is driven to perform ice breaking control. Steps (S42 ~ S46) and; Determining whether the ejector has reached a target stroke distance and completing a ribbing operation through a hall sensor, and stopping the ice control when the ejector reaches a target stroke distance (S47 to S48); If the ejector does not reach the target stroke distance, the operation time of the ejector checks whether the elapsed time exceeds a predetermined time, and when the predetermined time elapses, the ejector stops and notifies that the heater is defective (S49 to S51). Referring to the operation and operation of the invention in detail as follows.

먼저, 배관을 통해 급수된 물을 필터링하는 필터부에 의해서 정수된 물의 급수로를 선택적으로 차단 및 개방시키는 급수 밸브에서 배관을 통해 급수된 물을 제빙시킨후 이빙제어를 실시한다.First, the water supplied through the pipe is de-iced and the ice-making control is performed after the water supply valve selectively blocks and opens the water supply path of the purified water by the filter unit filtering the water supplied through the pipe.

상기 이빙제어를 하기위해서는 히터를 구동시킨후 온도센서를 통해 제빙용기의 온도를 감지한다(S41, S42).In order to perform the ice control, the temperature of the ice making vessel is sensed through a temperature sensor after driving the heater (S41, S42).

이는, 상기 제빙용기의 온도를 감지하여 히터의 열로 제빙용기에 만들어진 얼음을 제빙용기로부터 분리시키기 위함이다.This is to sense the temperature of the ice making vessel and separate the ice made in the ice making vessel from the ice making vessel by the heat of the heater.

이때, 상기 히터가 온도센서의 감지된 온도에 도달하면 그 히터를 정지시키고, 그 온도센서의 감지된 온도에 도달하지 않았다면 히터 구동시간이 일정시간을 경과했는지 판단하여 그 히터 구동시간이 일정시간을 경과하면 히터를 정지시킨다(S43~S45).At this time, when the heater reaches the detected temperature of the temperature sensor, the heater is stopped. If the heater does not reach the detected temperature of the temperature sensor, it is determined whether the heater driving time has elapsed for a predetermined time, and the heater driving time is a predetermined time. When it passes, the heater is stopped (S43 ~ S45).

상기 히터를 정지 시킨후, 이젝터를 구동시켜 제빙용기의 얼음을 이빙시킨다(S46, S47).After stopping the heater, the ejector is driven to ice the ice of the ice making container (S46 and S47).

만약, 상기 히터의 불량으로 이빙이 제대로 되지 않을경우, 상기 이젝터는 얼음을 제대로 이빙시키지 못하게 된다.If the ebbing is not performed properly due to the failure of the heater, the ejector may not properly ice the ice.

이를 위해, 제빙기의 홀센서를 이용하여 상기 이젝터의 움직임의 변화를 감지한후 상기 제빙기의 마이컴으로 그 감지된 위치신호를 출력한다(S48).To this end, after detecting a change in the movement of the ejector using the Hall sensor of the ice maker, and outputs the detected position signal to the microcomputer of the ice maker (S48).

이에 의해, 상기 이젝터가 얼음이 취출될수 있는 행정거리까지 도달하게 되면 상기 마이컴에서는 상기 홀센서의 출력신호를 입력받아 이빙제어를 정지시킨다(S49).As a result, when the ejector reaches the stroke distance at which ice can be taken out, the microcomputer receives the output signal of the hall sensor and stops the ice control (S49).

그러나, 상기 이젝터의 동작이 완료되지 않은, 즉, 목표 행정거리까지 도달하지 않은 상태면 마이컴에서는 그 이젝터의 구동후 일정시간 경과여부에 따라 그 이젝터의 구동을 정지시키고, 디스플레이창에 히터불량임을 표시한다(S50~S52).However, if the operation of the ejector is not completed, that is, the target stroke distance is not reached, the microcomputer stops driving the ejector according to whether the ejector is driven for a predetermined time and indicates that the heater is defective. (S50 to S52).

이상에서 상세히 설명한 바와 같이 본 발명은 이빙제어전에 히터의 동작시간과 센서온도를 동시에 판단하여 두가지 조건중에 한가지 조건이 만족되면 이빙제어를 실시하고, 만약 히터의 불량으로 이빙이 제대로 되지 않을경우(얼음을 이젝터가 제대로 이빙 시키지 못함) 이것을 제빙기가 감지(홀센서등을 이용)하여 이빙 제어를 정지시키고 히터의 불량을 판단할 수 있도록 함에 따라 제품의 효율성 및 신뢰성을 대폭향상시킬수 있는 효과가 있다.As described in detail above, the present invention determines the operating time of the heater and the sensor temperature at the same time before the ice-making control, and performs the ice-making control if one of the two conditions is satisfied, and if the ice-making is not performed properly due to the failure of the heater (ice ice). Ejector does not move properly. This can greatly improve the efficiency and reliability of the product as the ice maker senses (using Hall sensor etc.) to stop the ice control and determine the failure of the heater.

이상에서는 본 발명의 바람직한 실시예를 도시하고 또한 설명하였으나, 본발명은 상기한 실시예에 한정되지 않고, 이하청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술 분야에서 통상의 지식을 가진자라면 누구든지 다양한 변경 실시가 가능할 것이다.Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the above-described embodiments, and the present invention is not limited to the above-described claims, and the present invention may be used without departing from the gist of the present invention.
