오일댐퍼를 적용한 홈바도어를 구비하는 냉장고{REFRIGERATOR HAVING A HOME BAR DOOR WITH AN OIL DAMPER}Refrigerator with home bar door with oil damper {REFRIGERATOR HAVING A HOME BAR DOOR WITH AN OIL DAMPER}

본 발명은 냉장고에 관한 것으로서, 더욱 상세하게는 오일댐퍼를 홈바도어에 적용하여 진동, 소음 및 충격과 부품의 손상을 최소화함과 아울러 소비자 감성 만족도를 제고할 수 있는 오일댐퍼를 적용한 홈바도어를 구비한 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly, an oil damper is applied to a home bar door to minimize vibration, noise, impact, and damage to parts, and to provide a home bar door to which an oil damper is applied to improve consumer satisfaction. It's about a refrigerator.

최근 냉장고의 대형화 추세에 따라 도1에 도시한 바와 같이 홈바(5) 및 디스펜서(10)가 장착된 병립형(side by side) 냉장고가 출시되고 있다. 홈바(5)는 냉장실도어(15)를 열지 않고 내부에 보관중인 음료수 등을 꺼낼 수 있도록 하는 장치이고, 디스펜서(10)는 냉동실도어(20)를 열지 않고 내부의 냉수 또는 얼음을 외부로 취출 할 수 있는 장치이다.Recently, in accordance with the trend of larger refrigerators, side by side refrigerators equipped with a home bar 5 and a dispenser 10 have been released. Home bar (5) is a device that allows you to take out the beverage stored in the interior without opening the refrigerating chamber door (15), the dispenser (10) to take out the cold water or ice inside without opening the freezer door (20) It is a device that can.

도2는 도1에 도시한 종래의 냉장고의 홈바(5)의 구성을 보여주는 도면이다.FIG. 2 is a view showing the configuration of the home bar 5 of the conventional refrigerator shown in FIG.

도시한 바와 같이, 냉장고의 도어에 홈바(5)가 설치되고, 홈바(5)는 홈바도어(25)에 의하여 개폐되는 것으로, 홈바도어(25)를 열어서 홈바(5)의 내부에 보관중인 음료수 등을 간단하게 꺼낼 수 있게 된다. 이를 위하여, 냉장실도어(15)의 일부분을 소정 면적으로 뚫어 냉장실과 통하도록 개구부(30)를 형성하고 그 개구부(30)에 홈바도어(25)를 설치한다.As shown, the home bar (5) is installed in the door of the refrigerator, the home bar (5) is opened and closed by the home bar door (25), opening the home bar door (25) to drink the beverage stored in the home bar (5) I can easily take out a back. To this end, a portion of the refrigerating chamber door 15 is drilled into a predetermined area to form an opening 30 to communicate with the refrigerating chamber, and a groove bar door 25 is installed in the opening 30.

홈바도어(25)의 하면은 한 쌍의 경첩(35)에 의하여 개구부(30)의 내측 하면에 회동 가능하게 결합된다. 또한, 홈바도어(25)의 양 측면에는 한 쌍의 링크(40)가 결합되는데, 링크(40)의 일단은 홈바도어(25)의 측면에 회동 가능하게 결합되고, 타단은 개구부(30)의 내측 측면에 형성된 슬릿(45)에 회동 가능하게 삽입됨과아울러 슬릿(45)을 따라 가이드 되면서 이동될 수 있도록 결합된다. 따라서 홈바도어(25)의 개폐 시, 슬릿(45)에 결합된 링크(40)의 타단은 슬릿(45)을 따라 상하로 이동하면서, 개폐되는 홈바도어(25)를 지지하게 된다.The lower surface of the groove bar door 25 is rotatably coupled to the inner lower surface of the opening 30 by a pair of hinges 35. In addition, a pair of links 40 are coupled to both sides of the groove bar door 25, one end of the link 40 is rotatably coupled to the side of the groove bar door 25, the other end of the opening 30 It is rotatably inserted into the slit 45 formed on the inner side, and coupled to be moved while being guided along the slit 45. Therefore, when the home bar door 25 is opened and closed, the other end of the link 40 coupled to the slit 45 moves up and down along the slit 45 to support the home bar door 25 to be opened and closed.

그러나, 상기와 같은 홈바도어(25) 구조에서는 낙하 속도에 의하여 홈바도어(25)의 개방 마지막 순간에 덜컹거리는 소음 및 진동이 발생함과 아울러, 이로 인하여 홈바도어(25)의 경첩(35) 등에 손상을 가져오는 문제점이 있었다.However, in the structure of the groove bar door 25 as described above, the ratcheting noise and vibration are generated at the last moment of the opening of the groove bar door 25 by the drop speed, and thus the hinge 35 of the groove bar door 25 is caused. There was a problem that caused damage.

따라서, 이러한 문제점을 해결하기 위하여 대한민국 공개실용신안 제1999-0039442호 및 등록실용신안 제267213호에서는 홈바도어(25)의 힌지 축에 비틀림 코일 스프링을 장착하여 비틀림 코일 스프링의 탄성력에 의하여 홈바도어(25)가 서서히 개방될 수 있도록 하는 구성을 제안하고 있다.Accordingly, in order to solve this problem, Korean Utility Model Utility Model No. 1999-0039442 and Korean Utility Model Registration No. 267213 have installed a torsion coil spring on the hinge shaft of the groove bar door 25 to prevent the home bar door ( 25 is proposed to allow the opening slowly.

그러나, 이러한 구성에서는 홈바도어(25)에 그 폐쇄방향으로 상시 복귀 탄성력이 작용한다. 따라서, 홈바도어(25)의 개방 시에는 의도하는 감쇠력을 얻게 되지만, 반면 홈바도어(25)의 폐쇄 시에는 홈바도어(25)가 충격적으로 폐쇄되게 되는 문제점이 있었다. 또한, 계속적인 사용에 의한 스프링의 노후화에 의하여 그 탄성력 저하를 야기하여 설계된 감쇠력을 얻을 수 없게 되어, 내구성에 대한 소비자의 제품 불만족을 야기하는 문제점이 있었다.However, in such a configuration, the return bar always acts on the groove bar door 25 in its closing direction. Therefore, while the home bar door 25 is opened, an intended damping force is obtained, while the home bar door 25 is closed when the home bar door 25 is closed. In addition, due to the aging of the spring due to continuous use, the elastic force is reduced, the designed damping force can not be obtained, there is a problem that causes consumer dissatisfaction with durability.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 홈바도어의 개방 시 낙하 속도를 제어할 수 있도록 함으로써 홈바도어에 가해The present invention has been made to solve the above problems, an object of the present invention is to apply to the home bar door by controlling the falling speed when the home bar door is opened.

질 수 있는 진동, 소음 및 충격을 최소화할 수 있도록 하는데 있다.To minimize possible vibration, noise and shock.

이를 통하여, 부품의 손상을 최소화할 수 있게 되고, 아울러 홈바도어 개폐 시 안정감 증대로 소비자 감성 만족도를 제고할 수 있게 된다.Through this, it is possible to minimize the damage of the parts, and also to increase the customer satisfaction by increasing the stability when opening and closing the home bar door.

The rotating shaft 65a is fixedly coupled to rotate integrally with the hinge coupling shaft 60 to provide a damping force to the rotation of the groove bar door 25. The cylinder body 65b is fixedly coupled to the opening 30, and oil is filled therein.

오일댐퍼는 공지의 다양한 구조의 것이 사용될 수 있다. 예컨대, 대한민국 공개특허 제2002-0085267호에 개시된 오일댐퍼가 그 것이다. 이 경우, 홈바도어(25)의 개방 회전 시에는 상대적으로 큰 댐핑력을 주게 되고, 홈바도어(25)의 폐쇄 회전 시에는 상대적으로 작은 댐핑력을 줄 수 있게 된다.The oil damper may be one of various known structures. For example, the oil damper disclosed in Korean Laid-Open Patent Publication No. 2002-0085267. In this case, the open rotation of the home bar door 25 gives a relatively large damping force, and the closed rotation of the home bar door 25 can give a relatively small damping force.

이밖에도, 공개실용신안 제1996-18783에 개시된 오일댐퍼 등이 사용될 수 있다.In addition, the oil damper disclosed in the Japanese Utility Model No. 1996-18783 may be used.
