Description

냉장고의 소음저감구조{STRUCTURE FOR REDUCTION NOISE IN REFRIGERATOR}Noise reduction structure of refrigerator {STRUCTURE FOR REDUCTION NOISE IN REFRIGERATOR}

본 고안은 냉장고의 냉동 사이클에 관한 것으로서, 상세하게는, 냉매 유체의 소음을 효과적으로 저감시킴으로써 냉장고 전체의 소음을 줄여 쾌적한 환경을 제공할 수 있도록 하는 냉장고의 소음저감구조에 관한 것이다.The present invention relates to a refrigeration cycle of a refrigerator, and more particularly, to a noise reduction structure of a refrigerator capable of effectively reducing the noise of a refrigerant fluid and providing a pleasant environment by reducing the noise of the entire refrigerator.

일반적으로 냉장고는 냉장 및 냉동에 필요한 냉기를 제공하기 위해 도 1에 도시된 바와 같은 냉동 사이클을 채용하고 있다.Generally, a refrigerator employs a refrigeration cycle as shown in FIG. 1 to provide cold air for refrigeration and freezing.

이러한 냉장고의 냉동 사이클(101)은 도시된 바와 같이, 석션 파이프(120)를 통해 유입된 저온저압의 냉매를 압축하는 압축기(103)와, 방열 파이프(105)(107)(109)에 의해 고온의 냉매로부터 열을 방출시킨 다음 액화시키는 응축기(111)와, 드라이어(113)를 거쳐 유입되는 냉매를 저압상태로 팽창시키는 캐필러리 튜브(200) 및, 그 캐필러리 튜브(200)로부터 어큐뮬레이터(117)를 거쳐 유입된 냉매를이용하여 저열원으로부터 열을 흡수하는 증발기(119)로 이루어져 있다.The refrigeration cycle 101 of the refrigerator is a high temperature by the compressor 103 for compressing the low-temperature low-pressure refrigerant introduced through the suction pipe 120, and the heat radiation pipes 105, 107, 109 as shown. Condenser 111 for releasing heat from the refrigerant of the refrigerant and then liquefying the capillary tube 200 for expanding the refrigerant flowing through the dryer 113 to a low pressure state, and the accumulator from the capillary tube 200. It consists of an evaporator 119 that absorbs heat from the low heat source by using the refrigerant introduced through 117.

이와 같이 구성된 냉장고의 냉동 사이클(101)을 간략히 설명하면, 우선 압축기(103)에서 프레온 가스 등과 같은 냉매가 고온고압의 상태로 압축되어 보조 방열 파이프(105)로 공급된다. 이때, 보조 방열 파이프(105)는 통상적으로 냉장고의 하단부에 설치되므로 증발기(119)에서 제상된 물을 압축기(103)에서 전달되는 75℃ 내외의 고온으로 증발시키도록 되어 있다. 이 과정에서 고온의 냉매는 제상된 물을 증발시키는 데 필요한 열을 빼앗기게 되므로 일정 수준 냉각되는 부차적인 효과를누리게 된다.The refrigeration cycle 101 of the refrigerator configured as described above will be briefly described. First, in the compressor 103, a refrigerant such as a freon gas is compressed to a state of high temperature and high pressure and supplied to the auxiliary heat dissipation pipe 105. At this time, since the auxiliary heat dissipation pipe 105 is typically installed at the lower end of the refrigerator, the defrosted water from the evaporator 119 is evaporated to a high temperature of about 75 ° C. transmitted from the compressor 103. In this process, the high-temperature refrigerant is deprived of the heat required to evaporate the defrosted water and thus has a secondary effect of cooling to a certain level.

보조 방열 파이프(105)를 거친 냉매는 핫 파이프(107)를 거치게 되는데, 핫 파이프(107)는 일반적으로 냉장고의 도어측 캐비넷에 앞부분을 지나가도록 설치되어 있으므로 냉장고 도어를 여닫을 때 발생되는 냉장고 내부의 온도와 외부의 온도차로 인한 이슬맺침 현상을 방지하도록 되어 있는 것으로, 이 경우에도 발생된 수적을 증발시키기 위해 일정량의 열을 빼앗기는 냉매는 다시 한번 냉각이 이루어진다.The refrigerant passing through the auxiliary heat dissipation pipe 105 passes through the hot pipe 107. The hot pipe 107 is generally installed in the door side cabinet of the refrigerator to pass through the front part of the refrigerator. The dew condensation phenomenon caused by the temperature and the external temperature difference is prevented, and in this case, the refrigerant, which loses a certain amount of heat in order to evaporate the generated water drops, is cooled once again.

이와 같이 핫 파이프(107)를 경유한 냉매는 후판 파이프(109)와 응축기(111)를 거치면서 충분히 냉각되어 액화상태로 된 다음 드라이어(113)로 공급된다. 이때 드라이어(113)는 응축기(111)까지 거치면서 통과하면서 고온상태에서 저온상태로 냉각된 냉매속에 생성되어 잔류할 수 있는 수분을 냉매로부터 완전히 제거하는 역할을 하도록 되어 있다. 이는 위에서와 같이 수분이 잔류하는 냉매를 그대로 증발기(119)에 공급하여 열교환시킬 경우 냉매와 물의 열교환 계수차에 의해 냉각효율이 현저히 저하되는 것을 방지하기 위함이다.In this way, the refrigerant via the hot pipe 107 is sufficiently cooled through the thick plate pipe 109 and the condenser 111, becomes a liquefied state, and is then supplied to the dryer 113. At this time, the dryer 113 passes through the condenser 111 and serves to completely remove moisture remaining in the coolant that is generated in the coolant cooled from the high temperature state to the low temperature state. This is to prevent the cooling efficiency from being significantly lowered by the heat exchange coefficient difference between the refrigerant and water when the refrigerant remaining in the water is supplied to the evaporator 119 and heat exchanged as it is.

드라이어(113)를 거치면서 수분이 제거된 저온 고압의 냉매는 모세관 형태로 되어 있는 캐필러리 튜브(200)에 유입된다. 캐필러리 튜브(200)에서 냉매는 고압에서 저압으로 급격히 단열 팽창되어 저온 저압 상태로 되며 약 -30℃ 정도로 온도가 저하된다.The low temperature and high pressure refrigerant from which moisture is removed while passing through the dryer 113 flows into the capillary tube 200 which is in the form of a capillary tube. In the capillary tube 200, the refrigerant is rapidly adiabaticly expanded from high pressure to low pressure to a low temperature low pressure state, and the temperature decreases to about -30 ° C.

캐필러리 튜브(200)에 의해 저온저압 상태로 된 액상의 냉매는 증발기(119)에서 급격하게 기화되어 주위의 공기로부터 온도를 빼앗음으로써 냉동실 및 냉장실로 공급되는 냉기를 발생시키게 된다. 이때 증발기(119)에서 충분히 기화되지 못한 액상의 냉매는 어큐뮬레이터(117)로 분리되어 들어가게 되므로 압축기(103)로는 순수한 액체상태의 냉매만이 공급되게 된다.The liquid refrigerant, which is brought into a low temperature and low pressure state by the capillary tube 200, is rapidly evaporated in the evaporator 119 to deprive the temperature of the surrounding air to generate cold air supplied to the freezing compartment and the refrigerating compartment. At this time, the liquid refrigerant that is not sufficiently vaporized in the evaporator 119 is separated into the accumulator 117, so that only the pure liquid refrigerant is supplied to the compressor 103.

도 2는 캐필러리 튜브와 석션 파이프의 구조를 도시한 부분 확대도이다.Figure 2 is a partially enlarged view showing the structure of the capillary tube and the suction pipe.

도시된 바와 같이, 캐필러리 튜브(200)는 냉매의 단열 팽창을 위해 매우 길고 얇은 관 형태의 구조를 취하므로, 체적을 축소하기 위하여 둘러 감긴 구조의 권취부(210)를 구비한다.As shown, the capillary tube 200 takes a structure of a very long and thin tube for adiabatic expansion of the refrigerant, and thus has a winding 210 having a structure wound around to reduce the volume.

또한, 권취부(210)에서 연장형성된 열교환부(220)는 석션 파이프(120)에 근접하여 장착되는데, 이는 냉동 사이클이 필요충분한 냉매의 증발온도를 얻음과 동시에 응축온도를 낮추기 위한 구조이다.In addition, the heat exchanger 220 extending from the winding unit 210 is mounted in close proximity to the suction pipe 120, which is a structure for lowering the condensation temperature while at the same time obtaining a sufficient evaporation temperature of the refrigerant.

즉, 캐필러리 튜브(200)를 흐르는 냉매와 석션 파이프(120)를 흐르는 냉매 사이의 상호 열교환이 이루어짐으로써, 석션 파이프(120)의 저온 증발 냉매에 의해 캐필러리 튜브(200)의 응축 냉매는 과냉되고, 반대로 캐필러리 튜브(200)의 고온 응축 냉매에 의해 석션 파이프(120)의 증발 냉매는 과열되면서 완전히 증발되게 된다.That is, the mutual heat exchange between the refrigerant flowing through the capillary tube 200 and the refrigerant flowing through the suction pipe 120 is performed, whereby the low temperature evaporative refrigerant of the suction pipe 120 condenses the refrigerant in the capillary tube 200. Is supercooled, on the contrary, the evaporative refrigerant of the suction pipe 120 is completely evaporated by the high temperature condensed refrigerant of the capillary tube 200.

그런데, 종래의 상기와 같은 구조에 있어서는, 압축기의 운전 중 그 압축기의 진동이 석션 파이프를 거쳐 캐필러리 튜브의 권취부로 전달됨에 따라, 캐필러리 튜브의 진동을 일으켜 냉장고의 소음을 일으키는 주요 원인으로 지적되어 왔다.By the way, in the conventional structure as described above, as the vibration of the compressor is transmitted to the winding portion of the capillary tube through the suction pipe during operation of the compressor, the main cause of vibration of the capillary tube to cause noise of the refrigerator Has been pointed out.

본 발명은 상기와 같은 문제점을 해결하여, 석션 파이프와 캐필러리 튜브의열교환 구조를 유지하면서도 냉장고의 소음을 저감시킬 수 있는 구조를 제공함을 그 목적으로 한다.The present invention is to solve the above problems, to provide a structure that can reduce the noise of the refrigerator while maintaining the heat exchange structure of the suction pipe and the capillary tube.

In the refrigerator provided with a refrigeration cycle, the inner and outer parts separated by a heat insulating wall, it proposes a noise reduction structure of the refrigerator, characterized in that the winding portion of the capillary tube is buried inside the heat insulating wall.

이하, 첨부도면을 참조하여 본 발명의 실시례에 관하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3은 본 발명에 의한 냉장고의 소음저감구조를 도시한 부분 단면도이다.3 is a partial cross-sectional view showing a noise reduction structure of a refrigerator according to the present invention.

본 발명에 의한 소음저감구조는 기본적으로 도 1에 도시된 바와 같이, 체적을 축소하기 위하여 둘러 감긴 구조의 권취부(210)와, 압축기(103)에 냉매를 공급하는 석션 파이프(120)에 인접하여 장착된 열교환부(220)를 구비한 캐필러리 튜브(200)를 포함하는 냉동사이클을 구비하고, 내외부가 단열벽(130)에 의해 분리된 냉장고에 적용되는 것으로서, 도 3에 도시된 바와 같이, 캐필러리 튜브(200)의 권취부(210)가 단열벽(130) 내부에 묻혀 있는 것을 특징으로 하는 것이다.As shown in FIG. 1, the noise reduction structure according to the present invention is basically adjacent to a winding portion 210 having a structure wound around to reduce a volume and a suction pipe 120 supplying a refrigerant to the compressor 103. It is provided with a refrigeration cycle including a capillary tube 200 having a heat exchange unit 220 mounted therein, and the inside and the outside are applied to a refrigerator separated by a heat insulating wall 130, as shown in FIG. Likewise, the winding portion 210 of the capillary tube 200 is characterized in that it is buried in the heat insulating wall (130).

즉, 캐필러리 튜브(200)는 충분한 단열 팽창에 의해 저온 저압의 냉매를 생성하기 위해 상당히 긴 길이의 구조를 요하므로, 냉장고 내부에서 점유하는 체적을감소시키기 위해서는 둘러 감긴 구조의 권취부(210)가 필요한 것이고, 이 권취부(210)는 압축기(103)에 연결되는 석션 파이프(120)에 인접하여 장착되는 열교환부(220)와 일체로 형성되는 구조를 취하고 있다.That is, since the capillary tube 200 requires a considerably long length structure to generate a low temperature low pressure refrigerant by sufficient adiabatic expansion, the winding portion 210 of the wound structure is reduced in order to reduce the volume occupied in the refrigerator. ) Is required, and the winding part 210 has a structure formed integrally with the heat exchange part 220 mounted adjacent to the suction pipe 120 connected to the compressor 103.

따라서, 종래에 있어서는, 압축기(103)에서 발생하는 진동이 그대로 캐필러리 튜브(200)에 전달되게 되고, 별다른 구속을 받지 않는 구조를 취하는 권취부(210)가 진동에 의한 소음을 일으키는 원인이 되었는 바, 본 발명은 이 권취부(210)를 발포 폼(foam) 등에 의해 형성되는 냉장고의 단열벽(130) 내부에 묻어 넣는 구조를 취함으로써 상기와 같은 진동에 의한 소음을 원천적으로 봉쇄하고자 한 것이다.Therefore, in the related art, the vibration generated in the compressor 103 is transmitted to the capillary tube 200 as it is, and the winding portion 210 having a structure that is not restrained is causing the noise caused by the vibration. According to the present invention, the winding part 210 is buried in the heat insulating wall 130 of the refrigerator formed by a foam or the like, thereby fundamentally blocking noise caused by the vibration. will be.

이와 같은 구조를 취할 경우, 캐필러리 튜브(200)의 열교환부(200)는 석션 파이프(120)와 상호 열을 교환하는 구조를 유지한 채, 권취부(210)만이 주위와 단열되는 구조를 취할 수 있으므로, 증발기 입구의 건도를 증가시켜 냉동 사이클의 효율을 높인다는 부수적인 효과도 얻을 수 있다.In such a structure, the heat exchange part 200 of the capillary tube 200 maintains a structure in which heat is exchanged with the suction pipe 120, and the winding part 210 is insulated from the surroundings. As a result, the side effect of increasing the dryness of the evaporator inlet to increase the efficiency of the refrigeration cycle is also obtained.

또한, 상기 캐필러리 튜브(200)의 권취부(210)는 냉장고의 단열벽(130) 어디에 묻히는 구조를 취하더라도 본 발명의 목적을 달성할 수 있을 것이나, 석션 파이프(120)에 근접한 단열벽(130) 내부에 묻히는 구조를 취하는 것이 제작비의 절감, 단열 효과의 상승 등의 측면에서 더욱 바람직하다.In addition, the winding portion 210 of the capillary tube 200 may achieve the object of the present invention even if the structure is buried anywhere in the heat insulation wall 130 of the refrigerator, the heat insulation wall close to the suction pipe 120 It is more preferable to take the structure buried inside in view of reduction of manufacturing cost, increase of thermal insulation effect, and the like.

본 발명은 석션 파이프와 캐필러리 튜브의 열교환 구조를 유지하면서도, 냉장고의 소음을 저감시키고, 냉동 사이클의 효율을 높일 수 있는 냉장고의 소음저감구조를 제공한다.The present invention provides a refrigerator noise reduction structure capable of reducing the noise of the refrigerator and increasing the efficiency of the refrigeration cycle, while maintaining the heat exchange structure between the suction pipe and the capillary tube.
