Description

냉장고의 도어개방장치Door opener of refrigerator

본 발명은 냉장고의 도어개방장치에 관한 것으로써, 특히 냉동실 도어의 진공 부압을 간단한 구조로 해소시켜 도어가 손쉽게 개방될 수 있도록 한 냉장고의 도어개방장치에 관한 것이다.The present invention relates to a door opening device of a refrigerator, and more particularly, to a door opening device of a refrigerator in which a vacuum negative pressure of a freezer compartment door is solved in a simple structure so that a door can be easily opened.

일반적으로, 냉장고는 냉각사이클을 이용한 냉매(冷媒)의 증발열에 의해서 음식물을 냉동 및 냉장 보관하는 데 사용되는 가전제품으로, 냉각기에 의해 냉각된 냉기를 고내로 유입시켜 수납된 음식물을 냉동 및 냉장시키게 된다.In general, a refrigerator is a home appliance used to freeze and refrigerate food by the heat of evaporation of a refrigerant using a cooling cycle. A refrigerator is used to freeze and refrigerate stored food by introducing cold air cooled by a cooler into a refrigerator. do.

이러한 냉각사이클은 프레온 등의 가스 냉매를 고온 고압의 기체 냉매로 압축시키는 압축기(Compressor)와, 압축기로부터의 이송되는 고온고압의 기체 냉매를 외부 공기에 의해 냉각, 응축시켜 액화시키기 위한 응축기(Condenser)와, 응축기로부터의 액체 냉매를 감압시키기 위한 모세관(Capillary Tube)과 , 모세관으로부터의 감압된 냉매가 증발되면서 주위의 열을 흡수시켜 냉각시키기 위한 증발기(Evaporator) 등을 구비한다.Such a cooling cycle includes a compressor for compressing a gas refrigerant such as a freon into a gas refrigerant of high temperature and high pressure, and a condenser for cooling, condensing and liquefying gas refrigerant of high temperature and high pressure conveyed from the compressor by external air. And a capillary tube for depressurizing the liquid refrigerant from the condenser, and an evaporator for absorbing and cooling the surrounding heat while the depressurized refrigerant from the capillary is evaporated.

그런데, 통상의 냉장고는 그 외관적인 구조상 도 1에 도시된 바와 같이 일정용적의 캐비티를 가지는 캐비닛(1)과, 캐비닛(1)의 측면에 회전가능하게 마련되어 캐비티를 선택적으로 개폐시키기 위한 도어(2,3)로 대별된다.However, the conventional refrigerator has a cabinet 1 having a cavity having a predetermined volume, as shown in FIG. 1, and a door 2 which is rotatably provided at a side of the cabinet 1 to selectively open and close the cavity 2. And 3).

이 도어는 냉동실(F)과 냉장실(R)의 일측면에 상,하부 각각 힌지축 결합되고, 그 상,하부 도어(2,3)는 힌지축을 중심으로 소정각도 회전되어 고내를 선택적으로 개폐시키는 기능을 갖는다.The door is hinged to the upper and lower hinge shafts on one side of the freezer compartment F and the refrigerating compartment R, respectively, and the upper and lower doors 2 and 3 are rotated by a predetermined angle around the hinge axis to selectively open and close the interior of the chamber. Has the function.

이때, 상,하부 도어(2,3)에는 힌지축을 기준점으로 하여 그 타측에 사용자의 편의를 위하여 도어 손잡이(5)가 마련되어 있다.At this time, the upper and lower doors (2, 3) is provided with a door handle (5) for the convenience of the user on the other side of the hinge axis as a reference point.

그런데, 냉동실측의 상부도어(2)는 냉장실측의 하부도어(3)가 일회 개페된 후에 냉장실 고내의 압력이 냉동실 고내로 전달되어 진공 부압이 발생하게 된다.By the way, the upper door 2 of the freezer compartment side is opened once the lower door 3 of the refrigerating compartment side is opened once, the pressure in the refrigerating compartment chamber is transferred into the freezer compartment chamber to generate a vacuum negative pressure.

대용량의 냉장고일 경우, 사용자가 냉장실 하부도어를 개방시킨 후에 다시 닫을 때, 냉동실 고내에 큰 진공부압이 발생하게 되어 냉동실 상부도어를 개방시키고자 할 경우, 상부도어의 개방을 위하여 많은 힘이 요구된다.In the case of a large-capacity refrigerator, when the user opens and closes the lower door of the refrigerating compartment, a large vacuum negative pressure is generated in the freezer compartment, and a large amount of force is required to open the upper door. .

따라서, 종래에는 냉동실 고내의 진공부압을 해소하기 위한 별도의 부압해소수단이 요구되었다.Therefore, conventionally, a separate negative pressure releasing means for solving the vacuum negative pressure in the freezer compartment is required.

그 부압해소수단의 일 예로 첨부된 도면 도 2에 도시된 것을 설명하면, 일축상에 축 결합되어 좌,우 회전가능한 도어 손잡이(10)와, 도어 손잡이(10)의 회전에 따라 일방향 왕복 이동가능한 푸셔부재(30)와, 푸셔부재(30)의 이동을 가이드하는 측면 가이드(40)를 구비한다.As an example of the negative pressure releasing means attached to the accompanying drawings as shown in Figure 2, the shaft is coupled to one axis, the left and right rotatable door handle 10 and one-way reciprocating movement in accordance with the rotation of the door handle 10 The pusher member 30 and the side guide 40 which guides the movement of the pusher member 30 are provided.

더 상세히 설명하자면, 푸셔부재(30)는 일단에 소정의 탄성력을 갖는 판스프링(34)이 마련되며, 타단에는 도어 손잡이(10)의 회전시 슬라이딩되어 캐비닛의 전면 플랜지부에 접촉되는 접촉부(32)가 마련되어 있다.In more detail, the pusher member 30 is provided with a leaf spring 34 having a predetermined elastic force at one end thereof, and the other end of the pusher member 30 is slid when the door handle 10 is rotated to contact the front flange of the cabinet 32. ) Is provided.

또, 측면가이드(40)에는 푸셔부재(30)가 수용되는 요홈부가 형성되며 나사(60)에 의해 상호 결합된다.In addition, the side guide 40 is formed with a recess for receiving the pusher member 30 is coupled to each other by a screw (60).

이러한 구성을 갖는 종래 냉동실의 부압해소수단의 작용은, 먼저 사용자가 도어 개방을 위하여 도어 손잡이(10)를 좌,우 회전시키면, 도어 손잡이(10)가 회동되면서 푸셔부재의 판스프링을 길이방향으로 팽창시킨다.The function of the negative pressure releasing means of the conventional freezer having such a configuration is that when the user first rotates the door handle 10 to the left or right to open the door, the door handle 10 is rotated and the leaf spring of the pusher member is extended in the longitudinal direction. Inflate.

이후에 푸셔부재는 판스프링이 변형되면서 접촉부가 전면플랜지부의 표면에 직접 접촉되면서 밀어내게 된다.Thereafter, the pusher member is pushed while the plate spring is deformed and the contact portion directly contacts the surface of the front flange portion.

이에 따른 반작용으로 인하여 냉동실의 가스켓부위에 틈이 발생하게 되고, 이 틈새를 통해 외기가 고내로 유입되면서 부압이 해소된다.Due to this reaction, a gap is generated in the gasket portion of the freezer compartment, and as the outside air flows into the inside of the freezing chamber, the negative pressure is eliminated.

그런데, 이와 같은 종래 부압해소수단은 그 구성부품수가 과다하므로, 조립성 저하 및 원가상승등의 문제점을 갖게 된다.However, the conventional negative pressure releasing means has a number of components, so that there is a problem such as deterioration of assembly and cost increase.

본 발명은 상기한 제반문제점을 감안하여 안출된 것으로써, 그 목적은 간단한 구조로 냉동실 고내에 발생되는 진공부압을 용이하게 해소시킬 수 있도록 한 냉장고의 도어개방장치를 제공하는 데 있다.The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a door opening device of a refrigerator, which can easily solve the vacuum negative pressure generated in the freezer compartment with a simple structure.
