본 고안은 유아나 어린이들이 냉장고 도어를 쉽게 열지 못하도록 한 냉장고용 도어 인터록(Interlock) 장치에 관한 것이다.The present invention relates to a door interlock device for a refrigerator that prevents an infant or a child from easily opening a refrigerator door.

종래 냉장고도어는 냉장고 본체 전방에 경첩 또는 힌지로써 여닫을수 있게 설치한 것이며, 별도의 록크장치가 없이 단지 자석에 의해 임의로 개방되지 않도록 되어 있기 때문에 자기 판단력이 없는 유아나 어린이들이 쉽게 열수 있어 유아나 어린이들이 불필요하게 그리고 장난으로 자주 열게 되어 냉기 유출에 따른 전력낭비와 냉동 또는 냉장식품의 변질을 초래하게 되는 등 폐단이 있었다.Conventional refrigerator doors are installed to be opened and closed by hinges or hinges in front of the refrigerator body, and are not opened arbitrarily by magnets without a separate locking device, so infants or children without self-determination can easily open them. They were often opened unnecessarily and with mischief, resulting in wasted electricity and the deterioration of frozen or refrigerated foods.

따라서 본 고안은 이러한 종래의 폐단을 해소하기 위하여 국민학교 고학년 이상 성인들은 도어를 열수 있되 유아나 저학년 어린이들은 열지 못하도록 한 냉장고용 도어 인터록 장치를 제공하려는 것이다.Therefore, the present invention is to provide a door interlock device for a refrigerator so that adults can open the door, but not for infants or lower grade children to open the door in order to solve the conventional closing.

이하 본 고안을 첨부도면에 따라서 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도시한 바와 같이, 냉장고 본체 전면에 손잡이(2)가 달린 도어(1)를 개폐가능하게 설치한 통상의 냉장고에 있어서, 손잡이(2)의 상단부에는 도어(1)측으로 개방된 수평홈(3)와 상단면의 통공(5)과 연통되는 수직홈(4)을 형성하며, 선단에 걸림턱(7)이 형성된 랫치(6)을, 그 양측으로 돌출되는 힌지 축(8)이 수평홈(3) 양측내면에 형성된 안내홈(9) 내에 지지되도록 수평홈(3)에 삽입하여 수직홈(4)이 삽입된 스프링(10)에 의해 상시 선단측이 하향탄압되게 설치하고, 랫치(6) 후단에 천공된 나사공(11)에는 누름버튼(12)과 통공(5)에 삽통되는 나사(13)를 체결하며, 버튼 (12)의 상면에는 보호판(14)을 접착하고, 도어(1)에는 랫치(6)가 상하유동 가능하게 관통되는 관통공(15)을 천공하고, 본체측벽(16) 전면에는 상기 랫치(6)의 걸림턱(7)이 걸리는 걸림단턱(18)과 안내 경사면(19)을 보유하는 걸림홈(17)이 형성된 걸림편(20)을 삽입하여서된 것이다.As shown in the figure, in a conventional refrigerator in which a door 1 having a handle 2 is provided on the front of the refrigerator main body so as to be opened and closed, a horizontal groove 3 which is open toward the door 1 side at an upper end of the handle 2. And a vertical groove 4 which communicates with the through hole 5 of the upper end surface, and the latch shaft 6 having the latching jaw 7 formed at the front end thereof has a hinge shaft 8 protruding to both sides thereof. ) It is inserted into the horizontal groove 3 so as to be supported in the guide groove 9 formed on both inner surfaces thereof, and is always installed at the front end side by the spring 10 having the vertical groove 4 inserted therein, and the rear end of the latch 6. A screw hole 11 inserted into the push button 12 and the through hole 5 is fastened to the screw hole 11 drilled in it, and a protective plate 14 is attached to the upper surface of the button 12, and the door 1 is attached to the screw hole 11. The latch 6 drills a through hole 15 through which the upper and lower flows, and the engaging step 18 and the guide inclined surface 19 are applied to the main body side wall 16 in front of the latching step 7 of the latch 6. ) Engaging holding groove 17 will hayeoseo the insert retaining member (20) is formed.

상기 손잡이(2)는 일반적인 것과 마찬가지로 합성수지제로 성형하며 랫치(6)는 금속제로 제작하고 힌지축(8)은 랫치(6)와 일체로 성형하거나 또는 랫치(6)에 구멍을 뚫고 힌지축(8)을 양측에서 돌출되게 삽입고정한다.The handle 2 is formed of synthetic resin as in general, and the latch 6 is made of metal and the hinge shaft 8 is integrally formed with the latch 6 or by punching a hole in the latch 6 and the hinge shaft 8 ) And fix it so that it protrudes from both sides.

상기 스프링(10)은 버튼(12)를 유아나 어린이가 누르더라도 랫치(6)가 해지 작동되지 않을 정도로 탄성이 강한 것을 사용하여, 적어도 국민학교 고학년이상의 자기 판단력이 있는 사람이 엄지 손가락으로 세게 누를 경우에만 해지 작동되도록 한다.The spring 10 uses a strong elasticity so that the latch 6 does not terminate even when the infant or child presses the button 12, and when a person who has a self-determination power of at least a senior high school student presses hard with a thumb Only revocation should work.

상기 관통공(15)과 걸림홈(17)은, 일반적으로 냉장고 도어(1)와 본체측벽(16 )이 외부 금속판과 내부 단열재로 구성되는 것이므로 금속판과 단열재에 형성하는 것이다.The through hole 15 and the locking groove 17 are generally formed in the metal plate and the heat insulating material because the refrigerator door 1 and the main body side wall 16 are composed of an external metal plate and an internal heat insulating material.

또한 걸림홈(17)은 걸림단턱(18)이 단열재에 형성될 경우 강도면에서 문제가 있으므로 별도의 걸림편(20)을 금속제로 제작하여 삽입하는 것이 좋다.In addition, since the locking groove 17 has a problem in strength when the locking step 18 is formed in the heat insulating material, it is preferable to manufacture and insert a separate locking piece 20 made of metal.

미설명부호 21, 22는 손잡이(2)를 도어(1) 전면에 고정부착하기 위한 나사봉 및 너트이다.Reference numerals 21 and 22 are screw rods and nuts for fixing and attaching the handle 2 to the front surface of the door 1.

이와 같이 구성된 본 고안의 냉장고용 도어 인터록 장치는 도어(1)를 닫은 상태에서는 제2도의 실선 표시와 같이, 랫치(6)의 후단부가 스프링(10)에 의해 탄압되어 그 선단의 걸림턱(7)이 걸림편(20)의 걸림 탄턱(18)에 걸려서 손잡이(2)만 당겨서는 도어(1)가 열리지 않게 되며, 제2도 쇄선표시와 같이 누름 버튼(12)을 눌러서 랫치(6)의 후단부를 스프링(10)에 대항하며 하향 이동시킴으로써 랫치(6)의 선단부가 상향 회동되면서 걸림턱(7)이 걸림단턱(18)에서 해지되어야만 도어(1)를 열수 있게 되는 것이다.The door interlock device for a refrigerator of the present invention configured as described above has the rear end portion of the latch 6 pressed against the spring 10 in the state where the door 1 is closed, as shown by the solid line of FIG. ) Is caught by the locking tip 18 of the locking piece 20 so that only the handle 2 is pulled out so that the door 1 does not open, and as shown in FIG. 2, the push button 12 is pressed to open the latch 6. By moving the rear end downward against the spring 10, the front end of the latch 6 is rotated upward, so that the locking jaw 7 must be released from the locking end jaw 18 so that the door 1 can be opened.

여기서 상기 랫치(6)를 탄압하고 있는 스프링(10)의 탄성이 유아나 어린이들은 버튼(12)을 누르더라도 랫치(6)가 작동되지 않는 정도의 강도를 가지는 것이므로 유아들은 냉장고 도어(1)를 열수 없게 되며, 국민학교 고학년 이상의 사람은 손잡이(2)를 잡은 손의 엄지손가락으로 버튼(12)을 눌러서 랫치(6)를 해지시키면서 도어(1)를 열수 있는 것이다.In this case, the elasticity of the spring 10 that suppresses the latch 6 is such that the infant or children have a strength that the latch 6 does not operate even when the button 12 is pressed. It will not be opened, the person of the higher grade of the national school can open the door (1) while releasing the latch (6) by pressing the button 12 with the thumb of the hand holding the handle (2).

도어(1)를 연 상태에서 밀어서 닫으면, 랫치(6)의 선단부가 걸림홈(17)의 경사면(19)에 의해 안내되면서 랫치(6)의 선단이 상향 회동되면서 삽입되며 걸림턱 (7)이 경사면(19)를 지나면 스프링(10)의 탄력에 의해 랫치(6) 선단이 하향회동되어 걸림턱(7)이 걸림단턱(18)에 걸리게 되는 것이다.When the door 1 is pushed and closed, the front end of the latch 6 is guided by the inclined surface 19 of the locking groove 17 and the leading end of the latch 6 is inserted upward while the locking jaw 7 is inserted. After passing the inclined surface 19, the front end of the latch 6 is rotated downward by the elasticity of the spring 10 so that the locking jaw 7 is caught by the locking step jaw 18.

이상과 같이 본 고안에 의하면 자기 판단력이 있는 국민학교 고학년이상의 사람들은 한손으로 손잡이를 잡고 버튼을 눌러서 아무런 불편없이 도어를 열수 있으면서도, 유아나 어린이들은 버튼을 누르더라도 랫치가 작동되지 않아 도어를 열수 없게 되어 불필요한 전력소모와 냉동, 냉장식품의 변질을 방지할수 있는 것이다.According to the present invention as described above, people of higher grades who are self-determined can hold the handle with one hand and press the button to open the door without any inconvenience, but infants or children can not open the door because the latch does not work even if the button is pressed. It can prevent unnecessary power consumption and deterioration of frozen and refrigerated foods.
