침지돌기와 이를 포함하는 제빙유닛{Soak protrusion of ice making unit and ice making device comprising the same}Soak protrusion of ice making unit and ice making device comprising the same

본 발명은 침지부(제빙돌기,침지수단,냉각돌기등으로 불리며, 이하에서는 침지돌기라 함)와 이를 포함하는 제빙유닛(증발관에 침지돌기를 형성하고,물받이를 제외한 유닛이며, 이하 제빙유닛이라 함)에 관한 것으로 특히, 침지돌기의 표면 혹은 연결부의 용접,접합부분에 발생되는 부식등을 방지하기 위한 개선된 침지돌기와 이를 포함하는 제빙유닛에 관한 것이다. The present invention is an immersion unit (an ice making protrusion, an immersion means, a cooling protrusion, etc., hereinafter referred to as an immersion protrusion) and an ice making unit including the same (the immersion protrusion is formed in the evaporation pipe, except the drip tray, the ice making unit below, In particular, the present invention relates to an improved immersion protrusion and an ice making unit including the same to prevent corrosion occurring on the surface of the immersion protrusion or the welding of the immersion protrusion or the joint.

일반적으로 알려진 종래의 제빙기는 도 1a,도 1b에서 도시하는 바와 같이 공개특허 10-2011-0024722호등에서 알려진 얼음을 만드는 제빙장치(제빙기)등이 알려져 있다. Generally known conventional ice makers are known as ice makers (icemakers) for making ice, as shown in FIGS. 1A and 1B.

종래의 제빙장치는 냉각시스템(냉동사이클)을 갖춘 제빙기 본체와, 제빙유닛으로 이루어진다. 냉각시스템(냉동사이클)은 압축기와, 응축기, 증발관을 포함하며, 구동시 증발관의 주변을 냉각시킴으로써 증발관에 결합된 침지돌기에서 얼음이 생성되게 한다. 도 1b에서 도시하는 제빙판(제빙기판이라고도 함)은 판상의 상면에 제빙장치 냉각시스템과 연결되는 증발관이 형성되며, 증발관 하방으로는 공급된 물에 침지되는 침지돌기가 형성된다.Conventional ice makers comprise an ice maker body with a cooling system (freezing cycle) and an ice maker unit. The cooling system (refrigeration cycle) includes a compressor, a condenser and an evaporator tube, which, when driven, cools the periphery of the evaporator tube so that ice is produced in the immersion protrusions coupled to the evaporator tube. An ice making plate (also referred to as an ice making substrate) shown in FIG. 1B is formed on an upper surface of the plate to form an evaporating tube connected to the ice making system cooling system, and below the evaporating tube, an immersion protrusion is formed which is immersed in the supplied water.

제빙유닛은 제빙판에 형성된 증발관의 하방으로 침지돌기를 형성하고 이 침지돌기가 물에 침지되는 물받이로 이루어지며, 물접시에는 물이 주기적으로 채워지며, 제빙판의 하부에는 물에 침지되는 다수의 침지돌기가 적당한 높이의 침지상태를 형성한다. 물받이 일측에는 물받이를 기울여 물받이내에 결빙되지 않은 제빙수를 배출시키기 위한 선회수단이 구비된다. The ice making unit forms an immersion protrusion under the evaporation tube formed in the ice making plate, and the immersion protrusion is composed of drip trays which are immersed in water, and the water plate is periodically filled with water, and the lower part of the ice making plate is immersed in water. The immersion protrusions form a immersion state of a suitable height. One side of the drip tray is provided with pivoting means for discharging the ice-making water which is not frozen in the drip tray by tilting the drip tray.

한편, 이와 같은 제빙기와 증발관의 결합구조로는 첨부 도면 도 1c,도 1d에서 도시하고, 공개특허 10-2004-0085605호에서 알려진 제빙판은 제빙판 본체와, 제빙돌기로 이루어진다.제빙판 본체는 증발관에 결합되어 증발관의 냉각시 냉각되는 구조가 알려져 있다. 제빙판 본체는 증발관으로부터 냉기흡수가 용이하도록 구리(Cu)와 같은 열전도도가 양호한 금속재질로 성형되며, 제빙돌기들은 그 제빙판 본체의 성형시 일체로 형성되어 제빙판의 열전도 효율을 저하시키지 않도록 하고,증발관은 제빙판 본체의 상면에 형성된 장착홈에 프레스 압착되는 것으로, 제빙판 본체와 증발관의 결합을 위해 사용되던 종래의 방법들은 열손실이 나아지고,프레스 압착에 의한 증발관과 침지돌기들의 결합방법은 증발관의 외주면과 제빙판 본체의 접촉면적이 넓어지기 때문에 증발관에 의한 냉각효율은 상승되지만 침지돌기에서의 부식은 근본적으로 막지 못했고, 결합구조도 복잡했다. On the other hand, as a coupling structure of the ice maker and the evaporator tube as shown in Figure 1c, Figure 1d, the ice making plate known in the Patent Publication No. 10-2004-0085605 is composed of an ice making plate body and an ice making projection. It is known that the structure is coupled to the evaporator tube and cooled when the evaporator tube is cooled. The ice making plate body is formed of a metal material having good thermal conductivity such as copper (Cu) so as to easily absorb cold air from the evaporation tube, and the ice making protrusions are formed integrally when forming the ice making plate body to reduce the thermal conductivity efficiency of the ice making plate. The evaporation tube is press-pressed to the mounting groove formed on the upper surface of the ice-making plate body, and the conventional methods used for the combination of the ice-making plate body and the evaporation tube improve heat loss, and In the coupling method of the immersion protrusions, the contact area between the outer circumferential surface of the evaporator tube and the ice-making plate body is increased, but the cooling efficiency of the immersion protrusion is increased, but the corrosion in the immersion protrusion is not fundamentally prevented, and the coupling structure is complicated.

또한, 도 1e,도 1f에 도시하는 제빙유닛의 제빙판은 공개특허 10-2006-0036986호로 공개된 것으로, 복수의 침지돌기를 포함하지만, 이 도면에서 설명하는 종래 제빙판을 제조하는 방법은 제빙판이 알루미늄(Al) 재질을 사용했을 경우, 이 재질보다 열전도효율이 우수한 구리(Cu)합금으로 형성된 증발관을 사용하지만, 종래에는 땜납에 의해 제빙판과 증발관을 고정하는 작업을 하기 때문에 제빙판과 증발관의 재질이 다르게 되면 결합이 잘 되지 않아 증발관의 동파 및 부풀어오름 현상 등이 발생되어 장시간 사용할 경우 냉각효율이 저하될 수 있다는 문제점이 있었다. In addition, the ice making plate of the ice making unit shown in FIGS. 1E and 1F is disclosed in Korean Patent Laid-Open Publication No. 10-2006-0036986, and includes a plurality of immersion protrusions, but the method of manufacturing the conventional ice making plate described in this figure is When the ice sheet is made of aluminum (Al), an evaporation tube made of copper (Cu) alloy is used, which is more thermally efficient than this material. However, since the ice making plate and the evaporation tube are fixed by solder, If the material of the ice plate and the evaporation tube is different, the coupling is not good and the freezing and swelling phenomenon of the evaporation tube may occur, and thus the cooling efficiency may decrease when used for a long time.

첨부 도면중 도 1g,1h는 공개특허 10-2005-0022967호로 알려진 제빙기와 그에 적용된 제빙판에 관한 것으로 제빙판이 반원형을 이루고, 그 하방으로 침지돌기를 형성한 것으로 각 냉각핀(침지돌기)이 평판상으로 형성되지 않고, 다양한 형태로 이루어질 수 있음을 나타낸 예로써, 그 전열면적을 넓히기 위해 다수의 다각형 기둥 혹은, 다수의 원형의 기둥 형상을 이루도록 형성되었다. Figure 1g, 1h of the accompanying drawings relates to an ice maker and an ice making plate applied to the ice maker known in the Patent Publication No. 10-2005-0022967, the ice making plate is formed in a semi-circular shape, the submerged protrusions formed below each cooling fin (immersion protrusion) As an example showing that it can be made in various forms without being formed in a flat plate shape, it was formed to form a plurality of polygonal pillars or a plurality of circular pillars in order to increase the heat transfer area.

전술한 종래 알려진 모든 제빙판의 침지돌기 구조는 직접 물에 침지되는 형태이다. 따라서 이러한 침지돌기는 제빙관에 일체로 결합되는 부분으로서 제빙관과 침지돌기는 전도성이 높고 절곡성질이 좋은 구리, 알루미늄으로 제작되며, 제빙유닛의 침지돌기에서의 균의 증식문제를 해결하기 위하여 살균처리된다. The above-mentioned immersion protrusion structures of all the previously known ice making plates are in the form of being directly immersed in water. Therefore, the immersion protrusion is integrally coupled to the ice making tube. The ice making tube and the immersion protrusion are made of copper and aluminum having high conductivity and good bending properties, and are sterilized to solve the growth problem of bacteria in the immersion protrusion of the ice making unit. Is processed.

또한, 냉매가 충전된 제빙관의 코너부분에서는 표면 부식이 발생하기 쉬워 균의 증식이 자주 발생되므로 살균처리를 반복적으로 하게 된다.In addition, in the corner portion of the ice-making tube filled with the refrigerant, surface corrosion is likely to occur, and bacteria are often proliferated, so that the sterilization treatment is repeated.

한편, 스테인레스재질은 균의 증식이 거의 없어 최근 사용되어지고 있으나, 절곡 성질이 약한 단점이 있으며, 냉매가 채워지는 제빙관과 침지돌기의 결합방법이 기계적 접합인 경우 불량으로 인한 틈 발생율이 높다. On the other hand, stainless steel has been used recently because there is little growth of bacteria, but has a weak bending property, the high occurrence rate of cracks due to defects when the coupling method of the ice-making tube and the immersion protrusion is filled with the refrigerant.

또한, 냉매가 충진된 제빙관은 구리,알루미늄이어서 내압이 상승되면 부식되고, 부식되면 얼음에 포함되어 결국 인체에 해롭게 되므로 도금을 반복적으로 이루어지며, 도금을 해도 부식이 발생되므로 반복적인 도금이 실시될 수 밖에 없으며, 이러한 반복적 도금에 따른 손실도 증가되므로 비록 열손실이 많더라도 인체에 무해한 침지수단과 그 침지수단의 제조방법이 요구되는 것이다.In addition, the ice-making tube filled with the refrigerant is copper and aluminum, which is corroded when the internal pressure is increased, and when it is corroded, it is contained in ice and eventually becomes harmful to the human body. Therefore, plating is repeatedly performed. In addition, the loss due to the repeated plating is also increased, so even if there is a lot of heat loss immersion means harmless to the human body and a method of manufacturing the immersion means is required.

본 발명은 종래의 이러한 문제점을 감안하여 침지돌기의 표면 부식에 따른 문제점을 개선하고자 하는 데에 그 목적이 있다.The present invention has been made in view of the above problems in order to improve the problems caused by the surface corrosion of the immersion protrusion.

본 발명의 세부적인 목적은 부식율이 감소된 침지수단을 제공하는 데에도 있으며, 열손실을 감수하더라도 인체에 무해한 침지수단과 방법을 제공하는 데에 그 목적이 있다.It is a further object of the present invention to provide an immersion means having a reduced corrosion rate, and an object thereof is to provide an immersion means and a method that is harmless to a human body even at a loss of heat.

또한, 본 발명은 이러한 목적을 달성함과 아울러 제빙유닛의 증발관과 침지돌기들의 기계적 접합과정의 단점을 개선한 결합방법을 제공하는 데에도 그 목적이 있다. In addition, the present invention is to provide a method of achieving the above, and to provide a coupling method that improves the disadvantages of the mechanical bonding process of the evaporation tube and the immersion protrusions of the ice making unit.

The present invention is also to provide a immersion means of a stainless (sus) material that is weak in bending properties and disadvantages in terms of heat loss but little growth of bacteria and harmless to the human body.
