Abstract

The period of defrosting is extended by the separation of the cold duct to load a lattice plate on one evaporator. The lattice plate is placed on the evaporator situated on the cold duct in a refrigerator so as to separate the cold cycling path of cold room and refrigerating room. The defrosting heater(50) is placed only in the lower of the evaporator(60) placed on the cold duct(30) leading to the refrigerating room(20). The defrosting heater(50) is not placed in the cold duct(30) of the cold room(10), because the cold temperature of the cold room(10) is above zero about 3 deg.C , so it is not matter that the cooling pin(72) of the lattice plate(70) is covered by the frost. Also the covered ice cools the cold room(10). The cold having very low temperature is flowed into the evaporator(60) placed on the cold duct(30) in the refrigerating room(20) without frost, so that the operation period of defrosting heater is extended about five times.

본 발명은 냉기를 생성하는 냉장고의 증발기에 관한 것으로, 특히 냉기덕트에 설치된 하나의 증발기에 격판을 설치하여 냉장실 및 냉동실의 냉기순환통로를 각각 분리시키므로 제상주기를 최대한으로 연장한 냉장고에 관한 것이다.The present invention relates to an evaporator of a refrigerator for generating cold air, and more particularly, to a refrigerator having a plate installed in one evaporator to separate the cold air circulation passages of the refrigerating compartment and the freezing compartment, thereby extending the defrost cycle to the maximum.

일반적으로 간접냉각방식의 냉장고는 냉동실의 냉기순환통로와 냉장실의 냉기순환통로가 연통된 냉기덕트 적소에 증발기를 설치하여 송풍팬에 의한 풍량을 마이콤으로 적절히 자동조절하면서 냉장실과 냉동실로 냉기를 공급하고 한편, 증발기 하부에 제상히터를 설치하여 도어개방시 들어온 외기와 음식물로 부터 발생한 수분이 냉기와 함께 냉기통로에 유입되어 차가운 증발기에 착상된 성에를 일정한 주기마다 이 제상히터를 작동시켜 제상을수행하였다.In general, the indirect cooling method of the refrigerator provides an evaporator in the place of the cold air duct where the cold air circulation passage of the freezer compartment and the cold air circulation passage of the refrigerating compartment communicate with each other. On the other hand, a defrost heater was installed in the lower part of the evaporator to perform defrosting by operating the defrost heater at regular intervals for the frost formed on the cold evaporator by entering the cold passage along with the cold air. .

그러나 이와 같이 구성된 종래의 냉장고에 있어서, 특히 냉장실 및 냉동실의 증발기 사용률은 대략 20%:80%로 냉동실의 사용률이 월등히 높음에도 불구하고, 냉장실에서 냉기순환통로를 통해 유입된 영상의 냉기가 영하 30도의 증발기와 접촉하면서 증발기 전체에 착상을 유발시키므로 냉동실 및 냉장실의 냉각효율을 저하시킬 뿐만 아니라, 이 착상된 성에를 제상하기 위해 제상히터를 자주 작동시키므로 히터에서 발열된 열로 인해 상당한 에너지(냉기) 손실을 초래하게 되며, 또한 제상히터의 작동주기 단축으로 말미암아 전력손실이 커지는 문제점이 있었다.However, in the conventional refrigerator configured as described above, in particular, the use rate of the evaporator in the refrigerating compartment and the freezing compartment is about 20%: 80%, although the use rate of the freezing compartment is significantly higher, but the cold air of the image introduced through the cold circulation passage in the refrigerating compartment is minus 30 Not only does it lower the cooling efficiency of the freezer compartment and the refrigerating compartment by contacting the evaporator in Fig., But also frequently operates the defrost heater to defrost the frosted frost, which causes considerable energy (cold) loss due to the heat generated from the heater. In addition, due to the shortened operating cycle of the defrost heater there was a problem that the power loss increases.

그래서 본 발명은 상기와 같은 문제점을 감안하여 안출한 것으로, 냉장실의 냉기순환통로와 냉동실의 냉기 순환통로가 만나는 냉기덕트를 하나의 증발기에 격판을 설치하여 이를 분리하므로 냉장실 및 냉동실의 냉기순환통로가 각각 구분되도록 하는 한편, 각 냉기덕트 적소마다 별도로 작동하는 송풍팬을 설치하여 냉장실 및 냉동실에 냉기를 공급하므로써 냉기의 공급효율을 극대화하고, 냉장실에서 유입된 영상의 냉기에 의한 증발기의 착상을 최대한 억제하여 제상주기를 연장한 냉장고를 제공함에 그 목적이 있다.Therefore, the present invention has been made in view of the above-mentioned problems, and the cold air duct is formed by separating the cold air duct between the cold air circulation passage of the refrigerating compartment and the cold air circulation passage of the freezing compartment by installing a plate on the evaporator, and thus the cold air circulation passage of the refrigerating compartment and the freezing compartment. In addition, by installing a blower fan that operates separately for each cold air duct in place, supplying cold air to the refrigerating compartment and the freezing compartment maximizes the supply efficiency of the cold air, and suppresses the idea of the evaporator caused by the cold air of the image introduced from the refrigerating compartment. The purpose is to provide a refrigerator extending the defrost cycle.

따라서 본 발명은 이러한 목적을 달성하기 위하여 냉동실의 냉기순환통로와 냉장실의 냉기순환통로가 연통하면서 증발기가 설치된 냉기덕트를 분리시키되, 증발기 적소에 열전도가 탁월한 격판을 설치하여 냉기덕트 완전분리되도록 하는 한편, 상기 증발기를 냉동실의 냉기덕트측에 치중하도록 설치하여서 된 특징이 있다.Therefore, in order to achieve the above object, the present invention separates the cold air duct in which the evaporator is installed while the cold air circulation passage of the freezer compartment and the cold air circulation passage of the refrigerating compartment communicate with each other, and installs a plate having excellent thermal conductivity in place of the evaporator to completely separate the cold air duct. , Characterized in that the evaporator is installed so as to focus on the cold air duct side of the freezer compartment.

또한, 본 발명은 증발기에 격판을 설치하되, 증발기의 냉매관이 소정삽입되면서 면접되도록 냉매관의 형상과 일치하는 다수의 장홈을 격판에 형성하거나 장홈이 형성된 격판에 냉각핀을 다수개 형성하여서 된 특징이 있다.In addition, the present invention is provided by installing a plurality of diaphragm in the evaporator, a plurality of long grooves matching the shape of the refrigerant pipe to form a plurality of cooling fins on the plate or formed a plurality of cooling fins so as to interview the refrigerant pipe of the evaporator is inserted into the predetermined There is a characteristic.

본 발명은 또 냉동실의 냉기덕트에 치중되어 있는 증발기 하부에 제상히터를 설치하여서 된 특징이 있으며, 또한 양측 냉기덕트에 마이콤에 의해 독자적으로 작동을 수행하는 송풍팬을 각각 설치하여서 된 특징이 있다.The present invention is also characterized by the installation of a defrost heater in the lower part of the evaporator that is concentrated in the cold air duct of the freezer compartment, and also has the feature of installing each blower fan to perform the operation independently by the microcomputer in both cold air ducts.

이하, 본 발명의 일실시예를 첨부된 도면에 의거하여 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제3도는 본 발명에 따른 냉장고의 요부발췌 측단면도이고, 제1도 및 제2도는 본 발명에 따른 증발기를 발췌 도시한 것으로서, 냉장고(10) 및 냉동실(20)로 구분형성된 냉장고(1)에 있어서, 냉장실(10)의 후방과 상방에 냉기순환통로(31)를 형성하고, 냉동실(20)에도 마찬가지로 냉기순환통로(31')를 형성한 후 이 양측의 냉기순환통로(31)(31')가 연통되는 냉동실(20) 후벽에 냉기덕트(30)(30')를 구성하여 증발기(60)를 설치하되, 이 증발기(60)를 제1도 및 2도에서와 같이 양측으로 고정판(63)에 의해 고정지지되면서 일측으로만 냉각핀(62)이 수없이 구성되도록 냉매관(61)을 형성한 후 냉각핀(62)이 제거된 일측 냉매관(61)과 면접대응하도록 장홈(71)이 수개 형성된 격판(70)을 설치하여 증발기(60)가 냉동실(20)의 냉기덕트(30')에 치중되도록 냉기덕트(30)(30')를 분리하므로 상기 냉장실(10) 및 냉동실(20)의 냉기 순환통로(31)(31')가 완전히 분리되도록하고, 장홈(71)이 일측방으로 돌출된 격판(70)이 일측으로 냉각핀(72)을 설치하여 냉장실(10)로의 방출효율이 향상되도록 한 것이며, 또한 격판(70)을 사용한 증발기(60)의 분리기준은 통상적으로 냉동실(20)의 증발기(60)면적의 약 80%를 차지하고 있으므로 이에 맞도록 증발기(60)에 격판(70)을 고정설치한다.3 is a side cross-sectional view of the main portion of the refrigerator according to the present invention, and FIGS. 1 and 2 illustrate an evaporator according to the present invention, wherein the refrigerator 1 is divided into a refrigerator 10 and a freezer compartment 20. The cold air circulation passage 31 is formed at the rear and the upper side of the refrigerating chamber 10, and the cold air circulation passage 31 'is similarly formed in the freezing chamber 20, and then the cold air circulation passages 31 and 31' are formed on both sides. ) Is installed on the rear wall of the freezing chamber 20 through which the cold air duct 30, 30 ′ is installed, and the evaporator 60 is installed, and the evaporator 60 is fixed to both sides as shown in FIGS. 1 and 2. After the cooling fins 62 are fixed and supported only by one side, the coolant pipes 61 are formed so that the cooling fins 62 are formed only on one side, and the long grooves 71 are formed so as to correspond to the one side of the coolant pipes 61 from which the cooling fins 62 are removed. By installing the several formed diaphragms 70, the evaporator 60 separates the cold air ducts 30 and 30 ′ so that the evaporator 60 is focused on the cold air duct 30 ′ of the freezing chamber 20. The cold air circulation passages 31 and 31 'of the refrigerating compartment 10 and the freezing compartment 20 are completely separated, and the cooling fin 72 is installed at one side of the diaphragm 70 having the long groove 71 protruding to one side. The discharge efficiency to the refrigerating chamber 10 is to be improved, and the separation standard of the evaporator 60 using the diaphragm 70 generally occupies about 80% of the area of the evaporator 60 of the freezer compartment 20. The diaphragm 70 is fixed to the evaporator 60 so as to be fixed.

그리고 냉동실(20)과 통하는 냉기덕트(30')에 위치한 증발기(60)의 하부에만 제상히터(50)를 설치하고, 냉장실(10)의 냉기덕트(30)에는 제상히터(50)를 설치하지 않는데, 그 이유는 냉장실(10)의 냉기설정온도와 약 3℃의 영상이므로 격판(70)의 냉각핀(72)에 착상이 되더라 하더라도 별문제가 없을 뿐만 아니라, 오히려 이 착상된 얼음에 의해 냉장실(10)을 냉각시킬 수 있는 효과를 얻을 수 있으며, 또한 냉동실(20)의 냉기덕트(30')에 위치한 증발기(60)에는 냉동실(20)의 매우 낮은 영하의 냉기가 순환통로(31')를 거쳐 이 증발기(60)로 유입되기 때문에 착상이 거의 생기지 않으므로 기존의 제상히터 작동주기보다 약 5배 이상 그 주기를 연장하여도 된다.And the defrost heater 50 is installed only in the lower part of the evaporator 60 located in the cold air duct 30 'communicating with the freezing chamber 20, and the defrost heater 50 is not installed in the cold air duct 30 of the refrigerating chamber 10. The reason is that the image of the cold air set temperature of the refrigerating chamber 10 and the image of about 3 ℃, even if the cooling fin 72 of the diaphragm 70 is not a problem, but rather the refrigerating chamber by the ice implanted (10) can be obtained, and in the evaporator 60 located in the cold air duct 30 'of the freezer compartment 20, very low subzero cold air of the freezer compartment 20 is a circulation passage 31'. Since it is introduced into the evaporator 60 through almost no frosting, the period may be extended by about five times or more than the conventional defrost heater operating cycle.

또한 증발기(60)에서 생성된 차가운 냉기를 냉장실(10) 및 냉동실(20)로 공급하는 것은 송풍맨(40)(40')으로 하게 되는데, 이 송풍팬(40)(40')을 냉동실(20)의 냉기덕트(30')와 냉장실(10)의 냉기덕트(30)에 각각 설치하게 되며, 이의 제어는 냉장실(10) 및 냉동실(20)의 내부 각 적소에 온도센서를 설치하여 압축기(미도시)의 작동과 송풍팬(40)(40')의 운전을 별도의 마이콤 제어에 의해 작동되도록 하되, 바람직하게는 압축기는 냉동실(20) 부하조건에 따라 작동되도록 하고, 냉장실(10)은 송풍팬(40)의 ON/OFF에 의해 냉장실 (10)내부의 온도가 제어되도록 한다.In addition, the supply of cold cold air generated in the evaporator 60 to the refrigerating chamber 10 and the freezing chamber 20 is to be a blower man 40, 40 ', the blowing fan 40, 40' to the freezing chamber ( The cold air duct 30 'of the 20 and the cold air duct 30 of the refrigerating compartment 10 are respectively installed, and the control is performed by installing a temperature sensor in each of the internal places of the refrigerating compartment 10 and the freezing compartment 20. (Not shown) and the operation of the blowing fan 40 (40 ') to be operated by a separate microcomputer control, preferably the compressor is operated according to the load conditions of the freezer compartment 20, the refrigerator compartment 10 is The temperature inside the refrigerating chamber 10 is controlled by the ON / OFF of the blower fan 40.
