본 고안은 냉장고의 냉기(冷氣) 공급장치, 더욱 상세하게는 냉장실의 냉기순환 구조를 개선하여 저장식품의 신선도를 향상시킴과 동시에 절전 효과까지 얻을 수 있는 냉장고의 냉기 공급장치에 관한 것이다.The present invention relates to a cold air supply of the refrigerator, and more particularly to a cold air supply of the refrigerator to improve the fresh air circulation structure of the refrigerating compartment to improve the freshness of the stored food and at the same time save power.
일반적으로, 냉장고는 냉각싸이클에 의해 저온의 냉매가 흐르는 증발기의 일측에 냉각팬을 설치하여 냉동실과 냉장실에 강제로 공기를 순환시킴으로써 냉동 및 냉장기능을 수행한다.In general, the refrigerator performs a freezing and refrigerating function by installing a cooling fan at one side of an evaporator through which a low temperature refrigerant flows by a cooling cycle and forcibly circulating air in the freezing compartment and the refrigerating compartment.
이러한 종래의 냉장고의 구조하에서는 증발기를 통과한 약 -20℃ 정도의 냉기가 냉동실과 냉장실에 연결된 닥트를 통해 그대로 유입되었다. 상기의 냉기(약-20℃)는 냉동실에는 적합한 온도를 제공하는 반면, 냉장실에 보존되는 식품저장 온도치(약 3℃내외)에 비해 현저히 온도가 낮으므로 과냉각의 역효과가 발생하였다.Under the structure of the conventional refrigerator, about -20 ° C of cold air passing through the evaporator is introduced as it is through the duct connected to the freezer compartment and the refrigerating compartment. The cold air (about -20 ° C) provides a suitable temperature in the freezer, while the temperature is significantly lower than the food storage temperature value (about 3 ° C or so) stored in the refrigerating chamber, the adverse effect of the supercooling occurred.
또한 냉장실의 냉기의 흐름을 살펴보면, 증발기로부터 공급되는 냉기는 냉장고의 후벽면에 설치된 공급닥트의 유출공을 통해 전방으로 유출되는 한편 냉장실을 순환하여 열교환된 더운 공기는 재차 증발기로 향하는 제1도와 같은 유로(流路)를 형성하기 때문에, 냉장실내 일부 구석진 부위(A)등에서는 냉기의 공급 및 순환이 원활치 못해 식품의 신선도가 현저히 저하되기도 한다. 즉, 동일한 냉장실내에서 어떤 부위에서는 식품에 해가 될 정도의 과냉각이 발생하는 한편 또 다른 부위에서는 반대로 신선도가 떨어지는 불합리한 현상이 발생하였다.In addition, when looking at the flow of cold air in the refrigerating chamber, the cold air supplied from the evaporator flows out through the outlet hole of the supply duct installed on the rear wall of the refrigerator, and the hot air circulated through the refrigerating compartment is exchanged again to the evaporator as shown in FIG. 1. Since a flow path is formed, in some corners A and the like in the refrigerating chamber, the supply and circulation of the cold air is not smooth, and the freshness of the food is significantly reduced. That is, in some parts of the same refrigerating chamber, overcooling occurs to a degree that is harmful to food, while in another part, an unreasonable phenomenon of falling freshness occurs.
본 고안은 상기와 같은 종래의 문제점을 감안하여 안출한 것으로서, 본 고안의 목적은 적정저온의 냉기를 냉장실내 구석진 부위까지 고르게 공급함으로써 냉장실에 저장된 식품의 신선도를 향상시킴과 동시에 절전 효과까지 얻을 수 있는 냉장고의 냉기 공급장치를 제공하는 것이다.The present invention was devised in view of the above-described conventional problems, and an object of the present invention is to improve the freshness of the food stored in the refrigerating compartment and at the same time achieve a power saving effect by supplying evenly low temperature cold air to the corners of the refrigerating compartment. It is to provide a cold air supply of the refrigerator.
이러한 본 고안은 증발기에서 냉각된 공기를 냉장실에서 열교환된 더운 공기와 혼합시켜 냉장실에 공급하는 냉장고의 냉기 공급장치를 제공함으로써 달성된다. 이 냉기 공급장치는 증발기와 냉장실의 공기를 혼합하는 닥트와, 혼합된 공기를 적정온도의 냉기로 만들어 냉장실에 공급하는 공급팬과, 이 공급팬에 의해 냉장실의 전부분에 골고루 냉기를 배출시키는 공급닥트로 구성함에 따라 적정온도의 냉기를 냉장실내 구석진 부위까지 고르게 공급함을 특징으로 한다.The present invention is achieved by providing a cold air supply of a refrigerator in which the air cooled in the evaporator is mixed with the hot air heat exchanged in the refrigerating compartment and supplied to the refrigerating compartment. This cold air supply unit is a duct that mixes the air of the evaporator and the refrigerating compartment, a supply fan that makes the mixed air into a cool air at an appropriate temperature and supplies it to the refrigerating compartment, and a supply for discharging cold air evenly to all parts of the refrigerating compartment by the supply fan. As it consists of a duct, it is characterized in that it evenly supplies cold air at an appropriate temperature to the corner of the refrigerating chamber.
이하, 본 고안의 냉장고의 냉기 공급장치를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, the cold air supply of the refrigerator of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 종래의 냉장고의 내부를 보인 사시도이고, 제2도 (a)는 그 냉기의 순환경로를 보인 측단면도로서, 냉장고의 후방 하단부에 위치한 압축기(19)에서 고온고압으로 압축된 냉매는 냉장고의 후방 외벽에 설치된 응축기(15)를 지나면서 응축되고 이어서 모세관(도시 안된)을 거치는 과정에서 저온저압 상태로 되어 냉동실(10)과 냉장실(11)의 경계부에 위치한 증발기(16)를 통하여 열교환을 하는 냉각싸이클을 반복한다. 이 냉각싸이클 과정에서 증발기(16)의 후방부에 설치된 팬(17)은 냉동실(10)과 냉장실(11)에 설치된 각각의 닥트(12)(13)를 통하여 냉기를 강제순환시켜 냉동 및 냉장기능을 수행하고, 이 과정에서 냉장실(11)의 온도가 설정온도 이하로 내려가면 댐퍼(damper, 18)가 작동하여 냉장실 닥트(13)를 폐쇄함으로써 적정저온을 유지하도록 한다.1 is a perspective view showing the inside of a conventional refrigerator, and FIG. 2 (a) is a side sectional view showing a circulation path of the cold air, wherein the refrigerant compressed at high temperature and high pressure in the compressor 19 located at the rear lower end of the refrigerator is a refrigerator. After condensing through the condenser 15 installed on the rear outer wall of the condenser and then passing through a capillary tube (not shown), the state becomes a low temperature low pressure, and heat exchange is performed through the evaporator 16 located at the boundary between the freezer compartment 10 and the refrigerating compartment 11. Repeat the cooling cycle. During the cooling cycle, the fan 17 installed at the rear of the evaporator 16 is forced to circulate cold air through the respective ducts 12 and 13 installed in the freezing chamber 10 and the refrigerating chamber 11 to freeze and refrigerate. In this process, when the temperature of the refrigerating compartment 11 falls below the set temperature in this process, the damper 18 operates to close the refrigerating compartment doc 13 to maintain a proper low temperature.
한편, (b)는 냉장실닥트(13)의 일부를 보인 확대단면도로서, 상기의 증발기(16)로부터 공급되는 냉기가 냉장실닥트(13)의 벽면에 구비된 토출구(14)를 통해 냉장실(11)내로 바로 토출됨을 알 수 있다.On the other hand, (b) is an enlarged cross-sectional view showing a part of the refrigeration seal duct 13, the cold compartment 11 through the discharge port 14 provided on the wall surface of the refrigeration seal duct 13, the cold air supplied from the evaporator 16 It can be seen that it is discharged directly into.
앞서 언급한 바와 같이, 종래의 냉장고는 증발기(16)를 거친 저온의 냉기가 냉장실(11)로 바로 유입됨으로써 일부 과냉각의 문제가 있는 한편, 냉장실(11)내 냉기의 순환이 원활치 못함으로써 식품보존의 신선도에 큰 차이가 있게 되는 구조적 문제점을 안고 있다.As mentioned above, the conventional refrigerator has some problems of overcooling because the low temperature cold air passing through the evaporator 16 directly flows into the refrigerating compartment 11, while the circulation of the cold air in the refrigerating compartment 11 is not smooth, thereby preserving food. There is a structural problem that makes a big difference in the freshness of the.
제3도는 본 고안의 실시예의 냉기 공급장치를 구비한 냉장고의 내부 사시도로서, 냉장실(21)의 후벽에 적정온도의 냉기가 토출되는 토출구(23)와는 별도로 냉장실(21)의 내부 공기를 흡입하는 흡입구(24)가 별도로 구비되어 있다. 여기서, 상기의 토출구(23) 및 흡입구(24)는 2부분으로 분리된 별도의 닥트에 각각 연결된다.3 is an internal perspective view of a refrigerator provided with a cold air supply device according to an embodiment of the present invention, which sucks the internal air of the refrigerating compartment 21 separately from the discharge port 23 through which cold air at an appropriate temperature is discharged to the rear wall of the refrigerating compartment 21. The suction port 24 is provided separately. Here, the discharge port 23 and the suction port 24 are respectively connected to a separate duct divided into two parts.
또한, 제4도 (a) 및 (b)는 본 고안의 실시예의 냉기 순환경로를 보인 측단면도와 그 확대도로서, 냉장고의 후방 하단부에 위치한 압축기(28)에서 고온고압 상태로 된 냉매가 응축기(25)를 거쳐 응축되고 증발기(26)를 통하여 저온으로 냉각되는 통상적인 냉각싸이클을 순환한다.4 (a) and 4 (b) are side cross-sectional views and enlarged views of a cold air circulation path according to an embodiment of the present invention, in which a refrigerant at a high temperature and high pressure in a compressor 28 located at a lower rear portion of a refrigerator is condenser. It cycles through a conventional cooling cycle condensed via 25 and cooled to low temperature via an evaporator 26.
냉동실(20)과 냉장실(21) 사이에 설치된 상기 증발기(26)는 그 후면에 설치한 팬(27)에 의해 강제로 공기를 순환시켜 냉동 및 냉장기능을 수행한다.The evaporator 26 installed between the freezer compartment 20 and the refrigerating compartment 21 performs a freezing and refrigerating function by forcibly circulating air by the fan 27 installed at the rear side thereof.
냉장실(21)의 후벽면에는 상기 증발기(26)와 연통하여 수직으로 길게 혼합닥트(29)가 형성되고, 이 혼합닥트의 일측에는 냉장실(21)에 골고루 냉기를 토출하게 다수의 토출구(23)가 구비된 공급닥트(30)가 부설되어 있다.On the rear wall surface of the refrigerating chamber 21, the mixing duct 29 is formed vertically long in communication with the evaporator 26, and on one side of the mixing duct a plurality of discharge ports 23 for evenly discharging cold air to the refrigerating chamber 21. Supply duct 30 is provided is provided.
이때, 혼합닥트(29)와 공급닥트(30)의 사이에 위치한 차단벽(31)의 적당위치에 혼합닥트(29)로부터 공급닥트(30)로 냉기를 송풍시켜 주는 송풍팬(32)이 설치되고, 혼합닥트(29)에는 냉장실(21)에 연통하여 형성된 다수의 흡입구(24)가 연결되어 있다.At this time, a blowing fan 32 for blowing cold air from the mixing duct 29 to the supply duct 30 is installed at a suitable position of the blocking wall 31 located between the mixing duct 29 and the supply duct 30. The mixing duct 29 is connected to a plurality of suction ports 24 formed in communication with the refrigerating chamber 21.
따라서, 상기와 같은 본 고안의 냉장고의 냉기 공급장치는 증발기(26)의 후방에 설치된 팬(27)의 구동에 의해 냉기를 강제로 순환시키는 작용을 하게 되어, 상측의 냉동실(20)에는 공급닥트(22)를 통해 통상적인 바와 같은 냉동기능을 수행한다.Therefore, the cold air supply device of the refrigerator of the present invention as described above is to force the cold air by the drive of the fan 27 installed in the rear of the evaporator 26, supply duct to the upper freezing chamber 20 The refrigeration function as usual is performed through (22).
반면에, 냉장실(21)로 보내지는 냉기를 일차로 혼합닥트(29)로 보내지며, 이 혼합닥트에 설치된 송풍팬(32)은 증발기로부터 발생된 냉기의 유입을 가속시키는 한편, 냉장실(21)에 연결된 다수의 흡입구(24)를 통해 고내의 더운 공기를 혼합닥트(29)에 동시에 유입시킨다.On the other hand, the cold air sent to the refrigerating chamber 21 is primarily sent to the mixing duct 29, and the blowing fan 32 installed in the mixing duct accelerates the inflow of the cold air generated from the evaporator, while the refrigerating chamber 21 Hot air in the air is introduced into the mixing duct 29 through a plurality of inlets 24 connected to the same.
이에 따라, 증발기(26)로부터 냉각된 온도와 냉장실(21)의 온도가 혼합되어 냉장보관 온도에 적합한 온도로 변화되어 공급닥트(30)로 공급된 후, 다수의 토출구(23)를 통해 냉장실(21)로 토출된다.Accordingly, the temperature cooled by the evaporator 26 and the temperature of the refrigerating chamber 21 are mixed and changed to a temperature suitable for the refrigeration storage temperature and supplied to the supply doc 30, and then the refrigerating chamber through the plurality of discharge ports 23 ( 21).
또한, 상기의 공급닥트(30)에는 송풍팬(32)의 동작을 제어하는 온도조절기(33)가 장착되어 있어서, 공급닥트(30)내의 냉기의 온도에 따라 송풍팬(32)의 가동 및 정지를 조절함으로써 냉장실(21)로 유입되는 냉기의 온도를 항상 적정수준으로 유지한다.In addition, the supply duct 30 is equipped with a temperature controller 33 for controlling the operation of the blowing fan 32, the operation and stop of the blowing fan 32 in accordance with the temperature of the cold air in the supply duct 30 By controlling the temperature of the cold air flowing into the refrigerating chamber 21 is always maintained at an appropriate level.
아울러, 고내의 온도가 적정저온에 도달하여 팬(27)이 정지함으로써 증발기(26)로부터의 냉기가 공급되지 않는 경우에도, 별도로 설치된 송풍팬(32)을 가동하여 증발기(26) 주위에 체류하는 냉기를 흡인할 수 있으므로, 냉장실(21)내 적정 온도의 냉기공급이 가능한 특징도 있다. 즉, 증발기(26) 주위에서 정체상태로 있는 냉기를 활용함으로써 전체적으로는 절전 효과까지 얻을 수 있다.In addition, even when cold air from the evaporator 26 is not supplied because the temperature in the refrigerator reaches an appropriate low temperature and the fan 27 stops, the blower fan 32 installed separately is operated to stay around the evaporator 26. Since cold air can be sucked in, it is also possible to supply cold air at an appropriate temperature in the refrigerating chamber 21. In other words, by utilizing the cold air stagnated around the evaporator 26, a power saving effect can be obtained as a whole.
이와 같은 본 고안의 실시예는 혼합닥트(29)와 공급닥트(30)가 차단벽(31)을 사이에 두고 냉장실(21)의 후벽면에 형성된 것으로 설명하였으나, 각각 분리상태로 설치하는 것도 가능하거니와, 증발기(26)로부터 강제순환되는 냉기를 냉장실(21)에 직접적으로 공급하지 않고 식품보전에 적합하게 온도를 변화시켜 냉기를 공급하는 방법 및 기술은 모두 본 고안의 청구범위에 속한다.In this embodiment of the present invention, the mixing duct 29 and the supply duct 30 has been described as being formed on the rear wall surface of the refrigerating chamber 21 with the blocking wall 31 therebetween, but each can be installed in a separate state. In addition, methods and techniques for supplying cold air by varying the temperature appropriately for food preservation without directly supplying cold air forcedly circulated from the evaporator 26 to the refrigerating chamber 21 are all within the claims of the present invention.
이와 같은 본 고안은 냉장실의 온도를 전부분에 걸쳐 고른 상태를 유지토록 하여 식품저장 기능을 향상시킬 수 있는 효과와 절전 효과까지 얻는 장점도 있다.The present invention has the advantage of improving the food storage function and the power saving effect by maintaining the temperature of the refrigerating chamber evenly throughout.
