Description
본 고안은 냉장식품 및 냉동식품을 저장보관하는 냉장고에 관한 것으로써, 특히 전자석을 이용한 구동부를 수직형으로 설치하고 구조를 콤팩트화시킨 냉장고의 댐퍼구조에 관한 것이다.The present invention relates to a refrigerator for storing and storing refrigerated food and frozen food, and more particularly, to a damper structure of a refrigerator in which a driving unit using an electromagnet is installed vertically and the structure is compact.
일반적으로, 냉장고는 각종식품을 냉동 및 냉장된 상태로 저장하여 장시간 신선도를 유지시키는 장치로써, 도1에 도시한 바와 같이 증발기(40)가 내장된 중간벽(30)에 의해서 냉동식품을 저장보관시키는 냉동실(10)과 냉장식품을 저장보관시키는 냉장실(20)로 분리 구성되어, 냉각팬(50)에 의해 각 고내의 공기를 강제로 순환시켜 상기 증발기(40)와 연속적으로 열교환되도록 함으로써, 각 고내에 저장보관된 식품을 신선하게 저장보관시키는 것이다.In general, a refrigerator is a device for storing various foods in a frozen and refrigerated state to maintain freshness for a long time. As shown in FIG. 1, a refrigerator stores and stores frozen foods by an intermediate wall 30 having an evaporator 40 built therein. The freezer compartment 10 and the refrigeration chamber 20 for storing and storing the refrigerated food, which is separated, by forcibly circulating the air in each chamber by the cooling fan 50 to continuously heat exchange with the evaporator 40, The food stored in the store is to be kept fresh.
그리고, 상기 증발기(40)로부터 열교환된 냉기가 상기 냉장실(20)로 공급되도록 연통된 냉기공급구(21)에는 설정된 고내의 온도에 따라 냉기의 공급량을 제어하는 댐퍼(60)가 장착되어 있다.In addition, the cold air supply port 21 communicating with the cold air heat exchanged from the evaporator 40 to the refrigerating chamber 20 is equipped with a damper 60 for controlling the supply amount of cold air according to the set temperature inside the refrigerator.
이러한, 종래의 냉장고의 댐퍼구조는 도2에 도시한 바와 같이, 솔레노이드(61)가 수평으로 설치되고, 상기 솔레노이드(61)의 작동봉(611)의 단부에는 하부를 중심으로하여 외향으로 회동되도록 하단양측에 힌지(621)를 축설하고 배면에 밀폐판(622)을 부착시킨 개폐부재(62)가 구성되며, 상기 개폐부재(62)의 전면 하부에는 내향으로 탄성력을 작용하는 판스프링으로된 탄성부재(63)가 구성되어 이루어지는 것이다.In the damper structure of the conventional refrigerator, as shown in FIG. 2, the solenoid 61 is horizontally installed, and the end of the operating rod 611 of the solenoid 61 is rotated outward with the lower portion as the center. An opening and closing member 62 having hinges 621 arranged on both sides of the lower end and a sealing plate 622 attached to the rear surface thereof is configured, and an elastic spring is formed on the lower portion of the front surface of the opening and closing member 62 to exert an elastic force inwardly. The member 63 is comprised.
이와 같은 종래의 냉장고의 댐퍼구조는, 상기 개폐부재(62)가 상기 냉기공급구(21)를 폐색시킨 상태에서 고내의 온도가 설정온도 이상으로 되면 상기 솔레노이드(61)로 전원이 인가되어 작동봉(611)을 도2에 도시한 점선화살표와 같이 전방으로 이동시키게 된다.In the conventional damper structure of the refrigerator, when the opening and closing member 62 closes the cold air supply port 21 and the temperature inside the refrigerator is higher than the set temperature, power is supplied to the solenoid 61 to operate the rod. 611 is moved forward as shown by the dotted arrow shown in FIG.
또, 상기 솔레노이드(61)가 작동되면 상기 작동봉(611)의 단부에 연결된 상기 개폐부재(62)가 힌지(621)를 중심으로 외향으로 회동되어 상기 냉기공급구(21)의 전면으로부터 외향으로 이탈됨으로써 상기 증발기(40)에 의해 열교환된 냉기가 상기 냉장실(20)로 공급되게 된다.In addition, when the solenoid 61 is operated, the opening and closing member 62 connected to the end of the operating rod 611 is rotated outwardly about the hinge 621 to the outward from the front of the cold air supply port 21 By being separated, the cold air heat exchanged by the evaporator 40 is supplied to the refrigerating chamber 20.
그리고, 상기에서와 같은 과정을 통하여 냉기가 공급되어 상기 냉장실(20)의 온도가 설정온도 이하로 될 경우 상기 솔레노이드(61)로 인가되는 전원이 차단되어 작동봉(611)을 후방으로 복귀시키게 되는 것이며, 이때 상기 탄성부재(63)가 내향으로 탄력있게 복원됨과 동시에 상기 개폐부재(62)를 밀어 상기 냉기공급구(21)를 폐색시킴으로써 냉기의 공급을 차단하게 되는 것이다.When cold air is supplied through the same process as described above, when the temperature of the refrigerating chamber 20 becomes lower than or equal to the set temperature, power applied to the solenoid 61 is cut off to return the operating rod 611 to the rear. In this case, the elastic member 63 is elastically restored inwardly and at the same time, the opening and closing of the opening member 62 is closed to block the supply of cold air by closing the cold air supply port 21.
그러나, 이와 같은 종래의 냉장고의 댐퍼구조는, 구동수단인 솔레노이드가 수평으로 설치되므로써 구조가 복잡해지는 것은 물론이고 설치장소에 제약을 받게 되는 문제점이 있었고, 또한 비교적 큰 DC전압(약 50V)이 요구되어 전원공급장치가 복잡하여 제어가 난이하다는 문제점이 있었다.However, such a damper structure of the conventional refrigerator has a problem that the structure is complicated by the installation of the solenoid as the driving means horizontally and is restricted in the installation place, and a relatively large DC voltage (about 50 V) is required. There was a problem that the control is difficult because the power supply is complicated.
본 고안은 상술한 문제점을 감안해서 이루어진 것으로써, 본 고안의 목적은 전자석을 이용한 구동부를 수직형으로 설치하고 구조를 콤팩트화시킨 냉장고의 댐퍼구조를 제공하는데 있다.The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a damper structure of a refrigerator in which a driving unit using an electromagnet is installed vertically and the structure is compact.
이와 같은 목적을 달성하기 위하여 본 고안에 의한 냉장고의 댐퍼구조를 증발기로부터 열교환된 냉기를 제어하여 냉장실의 온도를 조절하는 냉장고의 댐퍼구조에 있어서, 함체상으로된 케이스에 코일이 주벽에 감겨진 코아를 수직으로 입설시키고, 그 일측에는 자속에 의해 힌지부재에 장착된 힌지축을 중심으로 전후방으로 회동되면서 개폐부재를 구동시킬 수 있도록 하단이 내향으로 절곡되고 상단이 외향으로 절곡된 구동부재로 구성된 구동부와, 상기 구동부의 상기 구동부재가 전후방향으로 회동되어 개폐부재를 작동시킬 수 있도록 안내공이 통공되고, 그 상부에는 냉기공급공이 통공된 지지대로 이루어진 것을 특징으로 한다.In order to achieve the above object, the damper structure of the refrigerator according to the present invention controls the cold air heat exchanged from the evaporator to control the temperature of the refrigerating chamber. And vertically, one side of which is rotated back and forth around the hinge shaft mounted on the hinge member by the magnetic flux, and the lower end is bent inward and the upper part is bent outward so as to drive the opening and closing member.

The elastic member 63 made of a spring is elastically installed.
이러한 본 고안의 댐퍼(60)를 좀더 구체적으로 설명하면, 상기 구동부(64)는 전자석의 원리를 이용하는 것으로, 이는 함체상으로된 케이스(641)에 코일(643)이 주벽에 감겨진 코아(642)를 수직으로 입설시키고, 그 일측에는 자속에 의해 힌지부재(648)에 장착된 힌지축(649)을 중심으로 전후방으로 회동되면서 상기 개폐부재(62)를 구동시킬 수 있도록 하단이 내향으로 절곡되고 상단이 외향으로 절곡된 구동부재(644)를 구성한다.The damper 60 of the present invention will be described in more detail, and the driving unit 64 uses the principle of an electromagnet, which is a coil 642 wound around a main wall of a coil 643 in a case 641 made of an enclosure. ) Vertically, and the lower side is bent inwardly so as to drive the opening and closing member 62 while being rotated back and forth around the hinge shaft 649 mounted on the hinge member 648 by magnetic flux on one side thereof. The upper end constitutes the driving member 644 bent outward.
또, 상기 케이스(641)의 내측벽에는 상기 구동부재(644)가 전후방향으로 회동되어 상기 개폐부재(62)를 작동시킬 수 있도록 안내공(646)이 통공되고, 그 상부에는 냉기공급공(647)이 통공된 지지대(645)를 구성한다.In addition, a guide hole 646 is formed in the inner wall of the case 641 so that the driving member 644 is rotated in the front-rear direction to operate the opening / closing member 62, and a cold air supply hole is formed thereon. 647 constitutes a perforated support 645.

The lower portion of the front will be equipped with an elastic member 63 that acts an elastic force in the cold direction.
다음은, 상기와 같이 구성된 본 고안에 의한 냉장고의 댐퍼구조의 작용효과를 도3을 찹조하여서 상세하게 설명한다.Next, the effect of the damper structure of the refrigerator according to the present invention configured as described above will be described in detail with reference to FIG.
먼저, 도3A에 도시된 바와 같이, 상기 개폐부재(62)가 냉기공급공(647)을 폐쇄시킨 상태에서 고내의 온도가 설정온도 이상으로 되면 상기 구동부(64)의 코일(643)에 비교적 낮은 DC전압(약 12V)가 인가되어서 상기 코아(642)에서 자력이 발생되고, 상기 코아(642)에서 발생되는 자력에 의해 상기 구동부재(644)가 힌지축(649)을 중심으로 회동되어 상기 구동부재(644)의 하단이 상기 코아(642)에 부착됨과 동시에 상기 구동부재(644)의 상단이 상기 지지대(645)의 안내공(646)을 따라 내향으로 이동되게 된다.First, as shown in FIG. 3A, when the opening and closing member 62 closes the cold air supply hole 647 and the temperature inside the refrigerator is higher than the set temperature, the coil 643 of the driving unit 64 is relatively low. A DC voltage (about 12 V) is applied to generate a magnetic force in the core 642, and the driving member 644 is rotated about the hinge shaft 649 by the magnetic force generated in the core 642 to drive the drive. The lower end of the member 644 is attached to the core 642 and the upper end of the driving member 644 is moved inward along the guide hole 646 of the support 645.
또, 상기 구동부재(645)의 상단이 상기 지지대(645)의 안내공(646)을 따라서 내향으로 이동되면 도3B에 도시한 바와 같이 상기 개폐부재(62)를 밀게되고, 상기 개폐부재(62)가 밀리게 되면 상기 개폐부재(62)가 힌지(621)를 중심으로 외향으로 회동되어서 상기 냉기공급공(647)으로부터 이탈됨으로써 상기 증발기(40)에서 열교환된 냉기가 상기 냉장실(20)로 공급되게 된다.In addition, when the upper end of the driving member 645 is moved inward along the guide hole 646 of the support 645, the opening and closing member 62 is pushed, as shown in Figure 3B, the opening and closing member 62 ), The opening / closing member 62 is rotated outwardly around the hinge 621 and is separated from the cold air supply hole 647 to supply the cold air heat-exchanged in the evaporator 40 to the refrigerating chamber 20. Will be.
또한 상기에서와 같은 과정을 통하여 상기 냉장실(20)로 냉기가 공급되어 상기 냉장실(20)의 온도가 설정온도 이하로 되면, 상기 구동부(64)의 코일(643)로 인가된 전원은 차단되어 상기 탄성부재(63)가 내향으로 탄력있게 복원됨과 동시에 상기 개폐부재(62)가 상기 냉기공급공(647)을 폐쇄시키므로써 상기 냉장실(20)로 공급되는 냉기를 차단시키게 되는 것이다.In addition, when cold air is supplied to the refrigerating compartment 20 through the same process as described above, and the temperature of the refrigerating compartment 20 is less than or equal to a predetermined temperature, the power applied to the coil 643 of the driving unit 64 is cut off. The elastic member 63 is elastically restored inward and at the same time, the opening and closing member 62 closes the cold air supply hole 647 to block the cold air supplied to the refrigerating chamber 20.
앞에서 설명한 바와 같이 본 고안에 의한 냉장고의 댐퍼구조에 의하면, 전자석을 이용한 구동부를 수직형으로 구성하여 구조를 간소화하고 부피를 축소시킴으로써, 제어전압을 안정화시킴과 동시에 설치장소의 제약을 받지 않게 된다는 매우 실용적인 효과가 있게 된다.As described above, according to the damper structure of the refrigerator according to the present invention, the drive unit using the electromagnet is vertically configured to simplify the structure and reduce the volume, thereby stabilizing the control voltage and not being restricted by the installation location. There is a practical effect.
