Description

냉장고용 디스펜서의 급수장치{APPARATUS FOR SUPPLYING WATER OF DISPENSER IN REFRIGERATOR}Water supply device of dispenser for refrigerator {APPARATUS FOR SUPPLYING WATER OF DISPENSER IN REFRIGERATOR}

본 발명은 냉장고용 디스펜서에 관한 것으로, 특히 자동제빙 기능을 함께 갖고 있는 냉장고에서 디스펜서의 급수장치에 관한 것이다.The present invention relates to a dispenser for a refrigerator, and more particularly, to a water supply device for a dispenser in a refrigerator having an automatic ice making function.

최근들어 냉장실과 냉동실 그리고 제빙기를 갖는 복합형 냉장고에 대한 수요가 크게 늘어나면서 그 기능 또한 다양해지고 있는 실정이다.Recently, as the demand for a combined refrigerator having a refrigerator compartment, a freezer compartment and an ice maker increases significantly, the functions thereof are also diversified.

이러한 자동제빙 및 디스펜서가 구비된 사이드 바이 사이드형 냉장고는 도 1에 도시된 바와 같이, 소정의 급수원(미도시)에 냉장고 본체, 보다 정확하게는 냉장실의 후벽측에 설치된 물탱크(1)가 연통되어 있고, 그 물탱크(1)의 일단은 냉동실에 설치된 자동제빙기(2)와 연통되는 한편 타단은 냉장실 도어에 설치된 디스펜서(3)와 연통되어 있다.As shown in FIG. 1, the side-by-side refrigerator equipped with such automatic deicing and dispenser communicates with the refrigerator main body to a predetermined water supply source (not shown), more precisely with a water tank 1 installed on the rear wall side of the refrigerating chamber. One end of the water tank 1 is in communication with the automatic ice maker 2 provided in the freezer compartment, while the other end is in communication with the dispenser 3 provided in the refrigerating compartment door.

상기 급수원(미도시)과 물탱크(1) 사이의 연결호스에는 급수되는 물을 정화시키기 위한 카본필터(4)가 개재되어 있고, 그 카본필터(4)와 급수원의 사이에는 급수량을 조절하기 위한 2방향 제1 물밸브(5)가 장착되어 있으며, 상기 물탱크(1)와 자동제빙기(2) 사이의 연결호스에는 카본필터(4)의 출구부에 연결되는 연결호스가 연통되는데, 상기 물탱크(1)와 자동제빙기(2) 그리고 카본필터(4)가 급수방향을 조정하기 위한 3방향 제2 물밸브(6)에 의해 서로 연통되어 있다.The connection hose between the water supply source (not shown) and the water tank 1 is interposed with a carbon filter 4 for purifying the water to be supplied, and the water supply amount is adjusted between the carbon filter 4 and the water supply source. A first two-way water valve (5) is mounted, and a connection hose connected to the outlet of the carbon filter (4) communicates with a connection hose between the water tank (1) and the automatic ice maker (2). The water tank 1, the automatic ice maker 2 and the carbon filter 4 communicate with each other by a three-way second water valve 6 for adjusting the water supply direction.

도면중 미설명 부호인 7은 얼음저장용기이다.In the drawings, reference numeral 7 denotes an ice storage container.

상기와 같은 종래의 자동제빙 및 디스펜서가 구비된 냉장고에서 사용자가 물 또는얼음 선택누름판(미도시)을 누르게 되면, 상기 물탱크(1)에서 물이 연결호스를 따라 흘러 외부로 디스펜싱되거나 또는 얼음저장용기(7)로부터 소정량의 얼음이 디스펜싱되는 것이었다.When the user presses the water or ice selection pressure plate (not shown) in the refrigerator equipped with the conventional automatic deicing and dispenser, water flows along the connection hose from the water tank 1 and is dispensed to the outside or ice. A predetermined amount of ice was dispensed from the reservoir 7.

여기서, 상기 물탱크(1)에 새로운 물이 채워지거나 또는 자동제빙기(2)에 새로운 물이 공급되기 위하여는 급수원(미도시)으로부터 새로운 물이 유입되어야 하는데, 이때 유입되는 수도수는 제1 물밸브(5)를 거쳐 카본필터(4)로 유입되고, 그 카본필터(4)를 거치면서 정화된 물은 제2 물밸브(6)에서 분리되어 물탱크(1) 또는 자동제빙기(2)로 흘러들어가게 된다.Here, in order for new water to be filled in the water tank 1 or new water to be supplied to the automatic ice maker 2, new water must be introduced from a water supply source (not shown). Water introduced into the carbon filter (4) via the water valve (5), the water purified through the carbon filter (4) is separated from the second water valve (6) and the water tank (1) or automatic ice maker (2) Will flow into.

즉, 사용자가 디스펜서(3)를 이용하여 물을 선택하게 되면, 그 디스펜서(3)와 연통된 물탱크(1)로부터 물이 배출되고, 그 배출되는 만큼의 물이 다시 급수원(미도시)으로부터 보충되는데, 상기 물탱크(1)의 높이가 통상 디스펜서(3)의 높이보다 낮은 위치에 배치되어 있으므로, 물 디스펜싱의 작동시는 새로운 물이 항상 급수원(미도시)으로부터 물탱크(1)로 공급되어야 충분한 수압을 유지할 수 있게 되는 것이었다.That is, when the user selects the water using the dispenser 3, the water is discharged from the water tank 1 in communication with the dispenser 3, and as much water as the discharged water is supplied again (not shown). Since the height of the water tank 1 is usually located at a position lower than the height of the dispenser 3, new water is always supplied from a water supply source (not shown) during the operation of water dispensing. ) To maintain sufficient water pressure.

반면에, 상기 얼음저장용기(7)에 수납되어 있는 얼음의 양을 감지하여 준비된 얼음의 양이 부족하게 되는 경우에는 새로운 제빙에 필요한 물이 자동제빙기(2)에 지속적으로 공급된다.On the other hand, if the amount of ice prepared by sensing the amount of ice contained in the ice storage container 7 is insufficient, water for new ice making is continuously supplied to the automatic ice maker 2.

그러나, 상기와 같은 종래의 자동제빙 및 디스펜서가 구비된 냉장고의 물 디스펜싱에 있어서는, 낮은 위치에 배치된 물탱크(1)로부터 높은 위치에 배치된디스펜서(3)로 물을 밀어올려 배출시켜야 함에 따라 물탱크(1)로 유입되는 물의 양이 항상 일정하지 않으므로 인해, 물디스펜싱 과정에서 그 배출되는 물의 양이 수압에 따라 각각 다르게 되는 것은 물론 배출시간도 일정하지 못하게 되는 문제점이 있었다.However, in the conventional water dispensing of the refrigerator equipped with the automatic de-icing and dispenser, water must be pushed out from the water tank 1 disposed at a lower position to the dispenser 3 disposed at a higher position. Accordingly, since the amount of water introduced into the water tank 1 is not always constant, there is a problem that the amount of water discharged during the water dispensing process is different depending on the water pressure, and also the discharge time is not constant.

따라서, 본 발명은 상기와 같은 종래의 냉장고가 가지는 문제점을 감안하여 안출한 것으로, 사용자가 물을 디스펜싱하는 과정에서 항상 균일한 양의 물이 배출되도록 하는 것은 물론 그 배출시간도 항상 일정하도록 하는 냉장고용 디스펜서의 급수장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made in view of the problems of the conventional refrigerator as described above, so that the uniform amount of water is always discharged in the process of dispensing the water of the user, as well as the discharge time is always constant. It is an object of the present invention to provide a water supply device for a refrigerator dispenser.
