도 1은 종래 기술에 따른 냉장고 자동제빙기의 급수 제어장치의 구성도이다.1 is a block diagram of a water supply control apparatus for an automatic refrigerator ice maker according to the prior art.
도 1을 참조하여 설명하면, 수도(10)에 직결되어 제빙용기(20)내로 제빙용수를 보내는 급수관(30), 상기 급수관(30)로상에 설치되는 급수밸브(40), 상기 급수밸브(40) 후방 일측의 급수관(20)로상에 설치되어 수압에 의해 회전하는 회전수차(50)로 구성된다.Referring to FIG. 1, a water supply pipe 30 directly connected to the water supply 10 and sending ice water to the ice making container 20, a water supply valve 40 installed on the water supply pipe 30, and the water supply valve 40. It is composed of a rotary aberration 50 which is installed on the water supply pipe 20 of the rear side and rotates by water pressure.

따라서, 수압의 변동에 의한 급수량의 변동으로 상기 제빙용기에 제빙되는 얼음의 크기가 달라지는 문제점이 있었다.Therefore, there is a problem that the size of the ice iced in the ice making container is changed by the change in the water supply amount due to the change in the water pressure.
본 발명은 상기한 종래기술의 제반 문제점을 해결하기 위하여 발명한 것으로서, 본 발명의 목적은 외부급수원의 수압을 감지하여 해당 수압에 부합하는 급수 시간을 선정하여 항상 외부 수압의 변화에 관계없이 일정량의 제빙용수가 제빙용기에 급수되도록 한 냉장고 자동제빙기의 급수 제어방법을 제공하고자 함에 있다.The present invention has been invented to solve the above-mentioned problems of the prior art, the object of the present invention is to detect the water pressure of the external water supply source to select a water supply time corresponding to the corresponding water pressure and always a certain amount regardless of the change in the external water pressure An object of the present invention is to provide a water supply control method for an automatic ice maker of a refrigerator, in which ice making water is supplied to an ice making container.

도 2는 본 발명에 따른 냉장고 자동제빙기의 급수 제어방법을 설명하기 위한 개략적 구성도이다.2 is a schematic diagram illustrating a water supply control method of an automatic refrigerator ice maker according to the present invention.
도 2를 참조하여 설명하면, 급수관(미도시)에 연결되어 있고 자동제빙기의 제빙용기(미도시)로 제빙용수를 공급하는 외부급수원(100), 상기 급수관 내부에 설치되어 있고 상기 외부급수원(100)에서 급수되는 수압을 감지하는 수압감지부(110), 상기 수압감지부(110)에서 감지된 정보를 인가받아 사전에 설정된 시간 만큼 상기 급수관에 설치된 급수밸브(120)를 개방시키는 제어부(130)로 구성된다.Referring to FIG. 2, an external water supply source 100 connected to a water supply pipe (not shown) and supplying ice-making water to an ice making container (not shown) of an automatic ice maker is installed inside the water supply pipe and the external water supply source. A control unit for opening the water supply valve 120 installed in the water supply pipe for a predetermined time by receiving the pressure detection unit 110, the information detected by the water pressure detection unit 110 for detecting the water pressure supplied from the water (100) ( 130).
이와 같이 구성된 냉장고 자동제빙기의 급수 제어의 동작을 도 3을 참조하여 설명하면 다음과 같다.The operation of water supply control of the refrigerator automatic ice maker configured as described above will be described with reference to FIG. 3.
먼저, 제빙을 위해 제어부(130)에서 급수밸브(120)를 개방시키면, 외부급수원(100)에 직결된 급수관을 통해 제빙용수가 제빙용기(미도시)에 급수된다.First, when the water supply valve 120 is opened by the controller 130 for ice making, the ice making water is supplied to the ice making container (not shown) through a water supply pipe directly connected to the external water supply source 100.
이때, 급수관로상에는 설치된 수압감지부(110)가 상기 외부급수원(100)에서 부터 흘러 내리는 수압(Wp)을 감지하여(S101) 감지된 정보를 제어부(130)로 인가한다.At this time, the water pressure detection unit 110 is installed on the water supply line senses the water pressure (Wp) flowing down from the external water supply source (100) (S101) and applies the detected information to the controller 130.
상기 수압감지부(110)는 외부급수원(100)에서 흘러 나오는 수압에 따라 1에서 9까지 순차적으로 가리키는 바늘이 구비된 눈금형식의 계량기이다.The pressure sensing unit 110 is a scale-type meter with a needle sequentially pointing from 1 to 9 in accordance with the water pressure flowing from the external water supply source (100).
그리고 상기 제어부(130)는 사전에 설정된 수압정보와 상기 수압감지부(110)의 바늘이 가리키는 수압정보를 비교한다.The controller 130 compares the previously set pressure information with the pressure information indicated by the needle of the pressure detecting unit 110.
상기 비교결과 수압정보 즉, 수압감지부(110)의 바늘이 눈금 1과 2 사이에 있으면(S102) 제빙용수의 흐름이 미약한 것으로 판단하여 급수밸브를 약 9초 동안 개방시켜 상기 제빙용기로 제빙용수를 공급한다(S103)(S104).As a result of the comparison, if the needle of the pressure information, that is, the pressure sensing unit 110 is between the scales 1 and 2 (S102), it is determined that the flow of ice making water is weak, and the water supply valve is opened for about 9 seconds to make ice by the ice making container. Water is supplied (S103) (S104).
만약, 상기 비교결과 수압정보 즉, 수압감지부(110)의 바늘이 눈금 2와 3 사이에 있으면(S105) 제빙용수의 흐름이 약한 것으로 판단하여 급수밸브를 약 8초 동안 개방시켜 상기 제빙용수로 제빙용수를 공급한다(S106)(S104).If, as a result of the comparison, the water pressure information, that is, the needle of the water pressure sensing unit 110 is between the scales 2 and 3 (S105), it is determined that the flow of the ice making water is weak, and the water supply valve is opened for about 8 seconds to make ice with the ice making water. Water is supplied (S106) (S104).
이런 비례 관계로, 즉 감지된 수압에 따른 수압감지부의 바늘 위치가 눈금 3 - 4, 4 - 5, 5 - 6, 6 - 7, 7 - 8 사이에 있을 때 각각 대응하여, 급수 밸브를 7초, 6초, 5초, 4초, 3초 동안 개방시키며 최종적으로 상기 비교결과 수압정보 즉, 수압감지부(110)의 바늘이 눈금 8과 9 사이에 있으면(S107) 제빙용수의 흐름이 강한 것으로 판단하여 급수밸브를 약 2초 동안 개방시켜 상기 제방용기로 제빙용수를 공급한다(S108)(S104).In this proportional relationship, that is, when the needle position of the hydraulic pressure sensing unit according to the detected hydraulic pressure is between the scales 3-4, 4-5, 5-6, 6-7, 7-8, respectively, the water supply valve is operated for 7 seconds , 6 seconds, 5 seconds, 4 seconds, 3 seconds to open and finally the comparison result of the hydraulic pressure information, that is, if the needle of the pressure detection unit 110 is between the scale 8 and 9 (S107) that the flow of ice-making water is strong Judging by opening the water supply valve for about 2 seconds to supply the ice-making water to the dike container (S108) (S104).
이때, 상기 제어부는 수압에 따라 급수밸브의 개방 동작시간를 체크하여 소정시간에 도달할 경우 급수밸브(120)를 폐쇄시키게 된다(S109). 이로써 제빙용기로 공급되는 제빙용수량은 공급되는 수압 변동에 관계없이 항상 일정하게 유지될 수 있다.At this time, the controller checks the opening operation time of the water supply valve according to the water pressure and closes the water supply valve 120 when the predetermined time is reached (S109). As a result, the amount of ice making water supplied to the ice making container can be kept constant regardless of the water pressure fluctuations supplied.
상기한 바와 같이 본 발명에 따른 냉장고 자동제빙기의 급수 제어방법은 자동제빙기의 외부급수원에서 공급되는 급수의 수압을 감지하여 해당 수압에 부합하는 급수 시간을 선정하여 항상 외부 수압의 변화에 영향을 받지 않고 일정량의 제빙용수가 제빙용기에 급수되도록 함으로써 소비자에게 제품에 대한 신뢰성을 높일 수 있는 효과를 가져오게 된다.As described above, the water supply control method of the refrigerator automatic ice maker according to the present invention detects the water pressure of the water supply supplied from the external water supply source of the automatic ice maker, and selects a water supply time corresponding to the corresponding water pressure so that it is not always affected by the change in the external water pressure. Instead, a certain amount of ice making water is supplied to the ice making container, thereby bringing an effect of increasing the reliability of the product to the consumer.
