Description

눈꽃빙수 제빙기{Snow shaved ice icemaker}{Snow shaved ice icemaker}

본 발명은 눈꽃빙수 제빙기에 관한 것으로서, 더욱 상세하게는 냉매가 공급되는 회전드럼을 열전도성이 좋은 알루미늄으로 구성하여 드럼의 두께를 스테인레스보다 두껍게 만들어 초기 가동시 온도편차로 인한 휨변형이 방지되도록 하고 또한 빙수가 쌓이는 냉장실은 고온 스팀청소를 할 수 있도록 함으로써, 보다 위생적으로 눈꽃빙수를 제공할 수 있는 눈꽃빙수 제빙기에 관한 것이다.More particularly, the present invention relates to an icemaker for iced snow water, and more particularly, to a rotary drum to which a coolant is supplied is made of aluminum having a good thermal conductivity so that the thickness of the drum is made thicker than that of stainless steel to prevent warp deformation In addition, the refrigerator room in which iced water accumulates can be cleaned by high temperature steam, and thus can provide more hygienic iced water for snow.

일반적인 제빙기는 실용등록 제474562호에 개시된 바와 같이 압축기로부터 공급되는 냉매가 드럼의 내부로 공급되면 드럼이 냉각되는데, 이때 드럼은 수조에 일부 잠긴 상태로 회전되면서 드럼 표면에 얼음이 생성된다. 이처럼 생성된 얼음은 드럼과 접한 칼날에 의해 긁혀져 빙수로 만들어진다.In a general ice maker, when the refrigerant supplied from the compressor is supplied to the inside of the drum as disclosed in U.S.P. No. 474562, the drum is cooled while the drum is partially submerged in the water tank, and ice is generated on the surface of the drum. The generated ice is scratched by the blade which is in contact with the drum and is made of ice water.

기존의 팥빙수는 분쇄한 얼음을 용기에 담고 토핑을 얹은 후 우유를 첨가하여 시원함과 고소함을 음미할 수 있는 여름철 별미로 제공되어 왔다. 하지만 우유를 첨가할 때, 분쇄된 얼음과 우유의 혼합이 제한되었으며, 우유로 인하여 분쇄된 냉동우유의 결빙상태가 약화되어 결빙상태를 유지할 수 없어 장시간 시원함을 느낄 수 없다는 문제점이 있었다. 이를 해결하기 위하여, 출원번호 제10-2001-0029192호 “눈꽃빙수의 제조방법”에서는 우유를 냉동시켜 결빙상태를 장기간 유지하면서 눈꽃처럼 세절되므로 시각적 효과를 발휘할 수 있는 방법을 제안하였다.Conventional deboned water has been served as a summer delicacy in which crushed ice is put into a container, topping is added, and milk is added to enjoy the coolness and the high quality. However, when milk is added, the mixture of crushed ice and milk is limited, and the iced state of the crushed frozen milk due to the milk is weakened, so that the frozen state can not be maintained and the coolness can not be felt for a long time. In order to solve this problem, Japanese Patent Application No. 10-2001-0029192, entitled " Method for manufacturing icing water for snow flakes, " proposed a method for freezing milk to keep the icing state for a long time,

그러나 회전드럼이 스테인레스로 되어서 열전도율이 낮기 때문에 드럼의 두께를 얇게 하였는데, 제빙기의 초기 가동시 드럼에서 냉매가 닿는 부분과 않 닿는 부분의 온도편차로 인하여 드럼 표면이 휨 변형되어 진원이 유지되지 않으므로 드럼 표면이 칼날에 긁혀 깎여 나가는 문제점이 있었다.However, since the rotating drum is made of stainless steel and the thermal conductivity is low, the thickness of the drum is made thin. However, since the surface of the drum is deflected by the temperature difference between the portion where the refrigerant comes in contact with the drum during the initial operation of the ice- There was a problem that the surface was scratched on the blade.

또한 회전드럼 내부로 냉매를 공급하는 중심축은 드럼을 관통하지 않고 드럼의 한쪽에 베어링으로 지지되다 보니 중심축의 편심으로 인하여 베어링이 쉽게 마모되어 냉매의 누설이 발생되는 등의 문제점이 있었다. 그리고 빙수를 저장하는 냉장실은 사용하지 않을 때 정기적으로 청소를 해야되나, 물청소 이외의 방법이 없어서 대장균이 서식할 수 있는 환경을 조성하여 위생상 불량한 등의 문제점이 있었다.Further, since the center axis for supplying the coolant to the inside of the rotary drum does not penetrate through the drum but is supported by bearings on one side of the drum, there is a problem that the bearing wears easily due to the eccentricity of the center shaft and leakage of the coolant occurs. However, there is a problem in that the refrigerator room for storing the iced water should be regularly cleaned when not in use, but there is no other way than cleaning the water, thereby creating an environment in which the coliform bacteria can live.

본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 냉매가 공급되는 회전드럼을 열전도성이 좋은 알루미늄으로 구성하여 드럼의 두께를 스테인레스보다 두껍게 만들어 초기 가동시 온도편차로 인한 휨변형이 방지되도록 하고 또한 빙수가 쌓이는 냉장실은 고온 스팀청소를 할 수 있도록 함으로써, 보다 위생적으로 눈꽃빙수를 제공할 수 있는 눈꽃빙수 제빙기를 제공함에 있다.SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a rotary drum to which a coolant is supplied is made of aluminum having a high thermal conductivity so that the thickness of the drum is made thicker than stainless steel, And the ice making machine is capable of cleaning the high temperature steam, thereby making it possible to provide ice water icing water more hygienically.

이를 위하여 본 발명은 압축기, 응축기 및 팽창변을 갖는 기계실; 제빙된 눈꽃빙수를 보관하는 냉장실; 그리고 회전드럼 표면에 결빙된 우유를 칼날로 긁어서 제빙하는 제빙실로 구성된 눈꽃빙수 제빙기에 있어서, 상기 회전드럼은 열전도성이 우수한 알루미늄으로 구성되고 표면은 세라믹으로 코팅되며, 상기 회전드럼의 외주면에는 다수의 홈이 형성되어 우유가 상기 홈 및 상기 회전드럼 표면에서 결빙되도록 하고; 상기 회전드럼은 내부에 중공상의 중심축이 관통되는데, 상기 중심축은 상기 기계실의 내벽에 고정되고, 상기 회전드럼의 양측은 상기 중심축의 외주면 베어링으로 회전지지되며; 상기 중심축은 내부의 격벽에 의해 양단이 입구와 출구로 구획되며, 상기 중심축의 외주면에는 상기 입구와 연결된 다수의 냉매노즐이 형성되고, 상기 중심축의 끝단에는 상기 출구와 연결된 연결구가 형성되어서 냉매가 상기 출구를 거쳐 상기 압축기로 회수되도록 한 특징이 있다.To this end, the present invention relates to a machine room having a compressor, a condenser and an expansion valve; A refrigerating chamber for storing iced ice-cooled ice water; And an ice-making chamber for melting ice on the surface of the rotary drum with a blade, wherein the rotary drum is made of aluminum having a high thermal conductivity, the surface of the rotary drum is coated with a ceramic, Grooves are formed to allow milk to freeze on the grooves and on the rotating drum surface; The rotary drum has a hollow central shaft penetrated therein, the central shaft being fixed to an inner wall of the machine room, both sides of the rotary drum being rotatably supported by an outer peripheral bearing of the central shaft; Wherein the center shaft is divided into an inlet and an outlet at both ends by an inner partition, a plurality of refrigerant nozzles connected to the inlet are formed on an outer circumferential surface of the central shaft, and a connecting port connected to the outlet is formed at an end of the central shaft, And is recovered to the compressor through an outlet.

본 발명에 따르면 열전도성이 스테인레스보다 우수한 알루미늄을 사용하여 드럼을 제작하면 스테인레스보다 드럼을 두껍게 형성할 수 있다. 따라서 제빙기의 초기 가동시 드럼의 한쪽으로 냉매가 분사되어 냉각되는 과정에서 드럼 반대쪽과의 온도 편차로 인한 드럼의 휨 변형이 방지된다. 드럼이 열전도성이 우수한 알루미늄으로 되어서 냉매가 분사된 지점에서 빠르게 주변으로 온도가 확산되어 드럼의 전체로 퍼지기 때문에 드럼의 온도편차가 신속하게 줄어든다.According to the present invention, when drums are manufactured using aluminum which is superior in thermal conductivity to stainless steel, the drums can be formed thicker than stainless steel. Therefore, during the initial operation of the ice maker, the coolant is sprayed to one side of the drum to prevent the drum from being warped due to a temperature deviation from the opposite side of the drum. Since the drum is made of aluminum with good thermal conductivity, the temperature rapidly diffuses from the point where the refrigerant is sprayed to the periphery and spreads to the entire drum, so that the temperature deviation of the drum is rapidly reduced.

그리고 드럼이 스테인레스보다 두껍기 때문에 휨변형이 방지되는 효과도 있다. 또한 드럼은 위생을 고려하여 표면을 세라믹도금 처리하여 칼날이 알루미늄과 직접 닿지 않도록 하였다.And since the drum is thicker than stainless steel, warping is prevented. In addition, the drum was plated with a ceramic surface to prevent direct contact of the blade with aluminum in consideration of hygiene.

또한 드럼은 외주면에 다수의 홈이 형성되어 초기 제빙시 유우가 홈에 파고들어 제빙되는데, 드럼 표면에 달라붙어 제빙되는 우유가 홈에서 제빙된 우유와 결합되어 드럼 표면에서 덩어리진 상태로 떨어지지 않고 칼날에 긁혀 빙수로 제빙되므로 빙수의 질이 우수해지는 이점이 있다.In addition, a plurality of grooves are formed on the outer circumferential surface of the drum to melt the milk into the grooves during the initial ice making process. The milk adhered to the surface of the drum to be defrosted is combined with the milk dewatered in the grooves, So that the quality of the ice water is improved.

또한 냉장실은 고온스팀이 분사되는 스팀노즐이 다수 구비되어서 제빙기를 사용하지 않거나 또는 정기적인 청소시 고온스팀으로 냉장실을 고온세척할 수 있으므로 대장균 같은 유해세균을 박멸할 수 있는 등의 이점이 있다.Also, since the refrigerator has a large number of steam nozzles for spraying high-temperature steam, the refrigerator can be cleaned at a high temperature with high-temperature steam when the user does not use the ice maker or periodically clean the refrigerator, so that harmful bacteria such as Escherichia coli can be eradicated.

In addition, the refrigerating chamber 20 is filled with a refrigerant tube through which the refrigerant flows, thereby maintaining the temperature of the refrigerating chamber 20 at a low temperature. A plurality of steam nozzles 21 are provided on the inner wall of the refrigerating chamber 20 to be connected to the steam generator 14. The ceiling of the refrigerating chamber (20) is formed with a passage (23) connected to the ice making chamber (30).

상기 제빙실(30)은 모터로 회전되는 회전드럼(40)이 구비되고, 회전드럼(40)은 하단이 우유통(31)에 잠겨서 회전드럼(40)의 표면으로 우유가 적셔진다. 그리고 회전드럼(40)의 외주면에는 칼날(32)이 구비되어서 우유가 회전드럼(40)의 표면에 결빙되면 이를 긁어서 빙수를 만들고 이때 만들어진 눈꽃빙수는 통로(23)를 따라 냉장실(20)에 쌓인다.The ice making chamber 30 is provided with a rotary drum 40 rotated by a motor and the lower end of the rotary drum 40 is immersed in the milk container 31 to milk the surface of the rotary drum 40. The outer peripheral surface of the rotary drum 40 is provided with a blade 32. When milk is frozen on the surface of the rotary drum 40, the ice is scratched to make ice water. .

상기 회전드럼(40)은 내부 중심에 중심축(50)이 관통된다. 상기 중심축(50)은 중공상으로 구비되는데, 상기 중심축(50)의 한쪽 끝단은 입구(51)가 형성되고, 반대쪽은 출구(52)가 구비되며, 상기 중심축(50)에는 입구(51) 및 출구(52)를 단절시키는 격벽(54)이 구비된다. 그리고 상기 격벽(54)의 한쪽에는 회전드럼(40) 내부의 냉매가 상기 출구(52)를 거쳐 상기 압축기(11)로 순환되도록 해주는 연결구(55)가 구비된다.The rotary drum 40 has a central axis 50 passing through its inner center. The center shaft 50 is provided with a hollow shape in which an inlet 51 is formed at one end of the central shaft 50 and an outlet 52 is provided at the opposite end thereof. 51 and the outlet 52 are provided. One end of the partition wall 54 is provided with a connecting hole 55 for circulating the refrigerant in the rotary drum 40 through the outlet 52 to the compressor 11.

상기 중심축(50)은 외주면에 다수의 냉매노즐(53)이 형성되어서 상기 입구(51)로부터 공급되는 냉매가 상기 냉매노즐(53)에서 상기 회전드럼(40)의 내주면으로 분사되도록 해준다. 그리고 상기 회전드럼(40)의 외주면에는 다수의 홈(41)이 등간격으로 구비되어서 우유가 회전드럼(40)의 표면에서 결빙될 때 일부가 홈(41)으로 파고들어 결빙되어서 회전드럼 표면의 결빙된 우유와 홈(41)에서 결빙된 우유가 서로 결합되어서 표면의 결빙된 우유가 조각으로 떨어져 나가지 않도록 해준다.The center shaft 50 has a plurality of coolant nozzles 53 formed on the outer circumferential surface thereof so that the coolant supplied from the inlet 51 is jetted from the coolant nozzle 53 to the inner circumferential surface of the rotary drum 40. A plurality of grooves 41 are equally spaced on the outer circumferential surface of the rotary drum 40 so that when the milk is frozen on the surface of the rotary drum 40, The frozen milk and the frozen milk in the groove 41 are bonded to each other to prevent the frozen milk on the surface from falling into the pieces.

상기 회전드럼(40)은 스테인레스보다 열전도성이 우수한 알루미늄 재질로 구성되어 스테인레스 보다 두께를 두껍게 구성할 수 있다. 따라서 온도편차에 따른 휨 변형이 방지된다. 그리고 두께가 두껍기 때문에 상기 홈(41)을 형성시킬 수 있으며, 특히 회전드럼(40)의 표면에는 위생을 고려하여 세라믹 재질로 코팅할 수 있다.The rotary drum 40 is made of an aluminum material having a higher thermal conductivity than stainless steel and can be made thicker than stainless steel. Therefore, warpage deformation due to temperature variation is prevented. In addition, the groove 41 can be formed because the thickness is thick. Particularly, the surface of the rotary drum 40 can be coated with a ceramic material in consideration of hygiene.

그리고 상기 회전드럼(40)의 양측 중심부는 상기 중심축(50)의 외주면과 베어링(42)으로 결합되어 회전지지 되며, 상기 중심축(50)은 양단이 제빙실(30)의 측벽에 고정 지지된다. 또한 상기 중심축(50)과 회전드럼(40)에서 베어링(42)으로 연결된 부분에는 패킹(43)이 더 구비되어서 냉매의 누설을 방지시킨다.Both sides of the rotary drum 40 are rotatably supported by the outer peripheral surface of the center shaft 50 by bearings 42. Both ends of the center shaft 50 are fixed to the side walls of the ice- do. A packing 43 is further provided at a portion of the rotary drum 40 connected to the bearing 42 by the center shaft 50 to prevent the refrigerant from leaking.

이처럼 구성된 본 발명 한 실시예의 제빙기는 상기 회전드럼(40)이 스테인레스 보다 열전도성이 우수한 알루미늄으로 구성되어서 두께를 키울 수 있으므로 온도편차에 따른 회전드럼(40)의 휨변형이 방지된다. 따라서 칼날(32)과 접촉되는 회전드럼(40)의 표면이 깎여나가는 일이 방지된다.In the icemaker of the embodiment of the present invention configured as described above, since the rotary drum 40 is made of aluminum superior in thermal conductivity to stainless steel, the thickness of the rotary drum 40 can be increased to prevent the rotary drum 40 from being bent. Therefore, the surface of the rotary drum 40, which is in contact with the blade 32, is prevented from being cut off.

이러한 본 발명 한 실시예의 제빙과정으로 설명하면, 먼저 상기 압축기(11)에서 냉매를 고온고압으로 압축시킨 뒤 상기 응축기(12)에서 냉매를 응축시키고 이후 팽창변(13)에서 냉매를 증발하기 좋은 상태로 만들어 준다. 이후 증발하기 좋은 상태의 냉매는 냉매관(미도시)을 따라 순환된 뒤 상기 입구(51)에서 상기 중심축(50) 내부로 공급된 뒤 상기 냉매노즐(53)에서 회전드럼(40)의 내부로 분사되어 회전드럼(40)을 냉각시킨다. 이때 회전드럼(40)은 우유통(31)에 담긴 우유에 일부가 잠긴 상태로 회전되므로 회전드럼(40)의 표면에 묻은 우유가 결빙된다.In the first embodiment, the refrigerant is compressed in the compressor 11 to a high temperature and a high pressure, then the refrigerant is condensed in the condenser 12, and then the refrigerant is evaporated from the expansion side 13 It makes it. The refrigerant is circulated along the refrigerant pipe (not shown) and then supplied into the center shaft 50 from the inlet 51 and then flows from the refrigerant nozzle 53 to the inside of the rotary drum 40 So that the rotary drum 40 is cooled. At this time, since the rotary drum 40 is partially rotated in the milk contained in the milk container 31, the milk on the surface of the rotary drum 40 is frozen.

회전드럼(40)의 표면에 우유가 결빙되면 회전드럼(40)과 접한 칼날(32)에 의해 결빙된 우유가 긁혀져서 빙수로 만들어지고, 이때 만들어진 눈꽃빙수는 통로(23)에서 냉장실(20)로 떨어져 보관된다. 상기 냉장실(20)은 저온 냉매가 순환되는 냉매관이 매설된 곳이므로 눈꽃빙수가 녹지 않는 저온을 유지한다.When the milk is frozen on the surface of the rotary drum 40, the frozen ice is scratched by the blade 32 in contact with the rotary drum 40 to make ice water. Lt; / RTI > Since the refrigerating chamber 20 is a place where the refrigerant pipe through which the low-temperature refrigerant is circulated is buried, the refrigerating chamber 20 maintains a low temperature at which the icing water of snow is not melted.

상기 회전드럼(40)에서 중심축(50)으로 공급된 냉매는 냉매노즐(53)에서 분사된 뒤 연결구(55)를 따라 출구(52)로 빠져나오고 이후 냉매관(미도시)을 따라 상기 압축기(11)로 순환되면서 냉동사이클을 구성한다. 상기 회전드럼(40)은 표면에 다수의 홈(41)이 형성되어 있는데, 우유의 초기 결빙시 우유가 홈(41)으로 파고 들어가 결빙되어 회전드럼(40) 표면에서 결빙되는 우유와 결합되어서 회전드럼(40) 표면에서 결빙된 빙질이 쉽게 떨어져 나가지 않는다. 따라서 칼날(32)에 의해 결빙된 우유가 긁혀지는 과정에서 회전드럼(40)의 표면에 결빙된 우유들이 긁혀질 때 갈리지 않고 덩어리로 떨어져 나가는 불량이 발생되지 않는다.The refrigerant supplied to the central shaft 50 from the rotary drum 40 is injected from the refrigerant nozzle 53 and then escaped to the outlet 52 along the connecting port 55 and then flows into the compressor 50 along the refrigerant pipe (11) to constitute a refrigeration cycle. The rotary drum 40 has a plurality of grooves 41 formed on the surface thereof. When the milk is initially frozen, the milk is poured into the grooves 41 to be frozen and combined with the milk to be frozen on the surface of the rotary drum 40, The frozen ice on the surface of the drum 40 does not easily fall off. Accordingly, when the frozen milk is scratched by the blade 32, there is no defect that the frozen milk on the surface of the rotary drum 40 is scratched off and separated from the frozen mass.

또한 제빙기를 정기적으로 청소하거나 또는 사용하지 않을 때 상기 냉장실(20) 내부에 마련된 스팀노즐(21)에서 고온의 스팀이 분사된다. 상기 스팀발생기(14)에서 발생된 스팀은 상기 스팀노즐(21)에서 분사되는데, 이때 분사되는 스팀에 의해 상기 냉장실(20) 내부는 고온으로 만들어져서 대장균 같은 유해세균이 멸균된다. 따라서 제빙기를 위생적으로 사용할 수 있다.Also, when the ice maker is periodically cleaned or not used, steam of high temperature is injected from the steam nozzle 21 provided in the refrigerating chamber 20. The steam generated in the steam generator 14 is sprayed from the steam nozzle 21, and the inside of the refrigerating chamber 20 is made hot by the sprayed steam at this time, thereby harmful bacteria such as Escherichia coli are sterilized. Therefore, the ice maker can be used hygienically.
