냉장고 도어 닫힘장치Refrigerator Door Closer

제1도는 본 고안을 적용한 냉장고의 사시도.1 is a perspective view of a refrigerator to which the present invention is applied.

제2도는 본 고안 장치의 회로도.2 is a circuit diagram of the device of the present invention.

본 고안은 냉장고 도어 닫힘 장치에 관한 것으로서 특히, 계수기, 도어개방 감지부, 도어닫힘 구동부 및 경고음 발생부등을 설치하여 소정시간동안 도어가 열렸으면 도어 닫힘 구동부가 작동되어 도어가 닫히도록하고, 닫히지 않을 경우 경보음을 울리도록한 냉장고 닫힌 장치에 관한 것이다.The present invention relates to a refrigerator door closing device, in particular, by installing a counter, a door open detection unit, a door closing drive unit and a warning sound generating unit, and the door is opened for a predetermined time to operate the door closing drive unit to close the door, If the refrigerator relates to a closed device to sound an alarm.

종래의 냉장고 도어는 사용자가 도어을 열고 식품을 넣거나 꺼낸 다음에 냉장고 도어를 닫았을때 내부의 식품용기에 도어내면이 걸리거나 사용자의 부주의로 도어가 밀착되지 못하고 미세하게 열리면 열려있는 상태에서 그대로 유지되기 때문에 냉장고내의 앤기가 계속 외부로 유출되어 콤프레셔를 연속 구동하게되므로 필요없는 전력손실을 크게될뿐아니라, 냉장고내에 보관중인 식품등이 손상되는 등의 단점이 있다.Conventional refrigerator doors are kept open when the door is opened to the food container inside when the user opens the door, puts food in or takes out the food, and then closes the refrigerator door, or when the door is inadvertently contacted by the user. Therefore, the Angi in the refrigerator is continuously leaked to the outside to drive the compressor continuously, so as to increase the unnecessary power loss, there is a disadvantage such as damage to food stored in the refrigerator.

본 고안은 이러한 종래의 단점을 해결하기 위하여 도어개방 감지부, 계수기, 도어닫힘 구동부 및 경고음 발생부등을 설치하여 도어가 소정시간동안 이상 열려져 있게 되면 도어닫힘 구동부를 작동시켜 도어가 자동으로 닫히도록 시도하고 그 결과에도 도어가 계속 열려있는 경우는 경보하여 냉장고 도어을 실수로 개방하여 놓는 거울 방지하여 전력낭비를 방지함과 동시에 냉장고 내부의 음싱의 손상을 방지할 수 있는 냉장고 도어 닫힘장치를 제공하는 것을 목적으로 하며, 이하 첨부된 도면을 참조하면서 본 고안의 구성 및 작용효과를 설명하면 다음과 같다.The present invention attempts to close the door automatically by operating the door closing drive unit when the door is opened for more than a predetermined time by installing a door open detection unit, counter, door closing drive unit and warning sound generating unit in order to solve this conventional disadvantage. The result is to provide a refrigerator door closing device that prevents a waste of power and at the same time prevents damaging the internal sound of the refrigerator by preventing a mirror that accidentally opens the refrigerator door when the door is still open as a result. With reference to the accompanying drawings, it will be described the configuration and effect of the present invention as follows.

제1도 및 제2도를 참조하면, 본 고안 장치는 냉장고 몸체(1)에서 도어(2)와 대향되는 위치에서 도어 개/폐를 감지하기 위한 가동자(3A)를 갖는 스위치(3) 및 도어(2)를 닫아주기 위하여 도어 패킹부 상/하에 설치되는 전자석(4A)(4B)과, 도어(2)가 열려있는 시간을 카운트하는 제1계수기(가)와, 제1계수기(가) 및 제2계수기(바)의 계수출력에 따른 도어닫힘 구동신호의 공급을 위한 OR게이트(나) 및 반전기(다)와, 상기 반전기(다)출력에 의하여 상기 전자석(4A)(4B)을 구동시켜 미세하게 열려있는 도어(2)를 닫아주기 위한 도어닫힘 구동부(라)와, 상기 제1계수기(가) 출력에 따라 도어닫힘 구동부(라)가 동작하여도 도어(2)를 닫지 못한 경우에 도어 닫힌 동작의 재시도에 이어서 공지의 경고음 발생부(마)를 동작시켜주는 제2계수기(바)와, 상기 제1계수기(가)에 클록을 공급해주는 펄스발생기(사)로 구성된다.1 and 2, the device of the present invention comprises a switch 3 having a mover 3A for detecting door opening / closing at a position opposite to the door 2 in the refrigerator body 1; Electromagnets 4A and 4B installed above and below the door packing part for closing the door 2, a first counter for counting the time that the door 2 is opened, and a first counter for And an OR gate (b) and an inverter (c) for supplying the door closing drive signal according to the counting output of the second counter (bar), and the electromagnets 4A and 4B by the output of the inverter (c). Door closing driver (D) for closing the door 2 that is finely opened by driving the door, and the door 2 cannot be closed even when the door closing driver D is operated according to the output of the first counter. In this case, following the retry of the door closing operation, a clock is provided to the second counter (bar) and the first counter (a) to operate the known warning sound generating unit (e). Which consists of a pulse generator (G).

미설명 부호 R1 내지 R13은 저항, C1, C2는 콘덴서, B+<ACV는 전원, D1 내지 D5는 다이오드, D6는 LED, T1, T2는 트랜스, CL은 전자석 구동코일, F1 내지 F11은 플립플롭, Q1 내지 Q10은 트랜지스터, 5는 플립플롭, 6은 반전기이다.R1 to R13 are resistors, C1 and C2 are capacitors, B + <ACV is power supply, D1 to D5 are diodes, D6 is LED, T1 and T2 are transformers, CL is electromagnet drive coil, F1 to F11 is flip-flop, Q1 to Q10 are transistors, 5 is flip-flop, and 6 is an inverter.

이러한 본 고안 장치의 작용효과는 우선, 사용자가 부주의로 냉장고 도어(2)를 열었다가 완전히 닫지 않게 되면 육안식별이 즉시 이루어지기 어려운 미세한 틈새가 생기게 되고 이때 가동자(3A)를 냉장고도어(2)가 누르지 못하여 스위치(3)는 오프상태가 된다.The operation and effect of the device of the present invention, first, when the user inadvertently opens the refrigerator door 2 and does not close it completely, there is a fine gap which is difficult to visually identify immediately, and the mover 3A is moved to the refrigerator door 2. Is not pressed, the switch 3 is turned off.

이때 스위치(3)에 공급되는 직류전원(B+)은 콘덴서(C1)에 의하여 도어의 치최 개방시에 플립플롭(F1-F11)의 리세트단자(R) 인가되어 플립플롭(F1-F<)를 세트시킨다.At this time, the DC power supply B + supplied to the switch 3 is applied to the reset terminal R of the flip-flop F1-F11 by the condenser C1 at the time of opening of the door. Set it.

이상태에서 가정용 전원은 60Hz 100V 또는 60Hz 220V이므로 이러한 교유전원을 강화시켜(대략 4.5V정도) 펄스발생기(사)의 플립플롭(F10, F11)의 코들입력으로 사용한다.In this state, the home power supply is 60Hz 100V or 60Hz 220V, so this kind of power supply is strengthened (approximately 4.5V) and used as the codle input of the flip-flops F10 and F11 of the pulse generator.

따라서 플립플롭(F1-F7)은 각각의 출력이 각각의 입력에 연결되어 있으므로 지연기로서 작동하게 된다.Thus, flip-flops F1-F7 operate as delays because their respective outputs are connected to their respective inputs.

따라서 제1계수기(가)의 플립플롭(F7)의 출력(Q)에 하이가 발생되면 OR게이트(나)와 반전기(다)를 통하여 도어닫힘 구동부(라)의 트랜지스터(Q3)의 베이스에 '로우'전위를 인가하므로 트랜지스터(Q6, Q7, Q9)가 차례로 온되어 전자석 코일(CL)에 전류를 인가하게 되므로 전자석 코일이 여기되어 도어패킹부의 전자석($A)(4B)구동에 의한 자력으로 이곳에 근접하여 열린채로 있는 냉장고 도어(1)를 닫게 된다.Therefore, when high occurs at the output Q of the flip-flop F7 of the first counter (A), the OR gate (B) and the inverter (C) are applied to the base of the transistor (Q3) of the door closing driver (D). Since the 'low' potential is applied, the transistors Q6, Q7, and Q9 are sequentially turned on to apply current to the electromagnet coil CL, so that the electromagnet coil is excited and the magnetic force of the electromagnet ($ A) (4B) of the door packing part is driven. This closes the refrigerator door (1) that remains open close to this place.

이 전자석(4A)(4B)의 자역으로도 도어(2)가 닫히지 않으면, 소정시간이 지나면 제2계수기(바)의 플립플롭(F8)의 출력(Q)이 하이가 되어 도어닫힌 구동부(라)가 재차 동작하고 그래도 도어(2)가 닫히지 않게 되면 다음 클록의 타이밍에서 플립플롭(F9)의 출력(Q)이 하이가 되어 경고음 발생부(마)가 작동되어 발광다이오드(D6)가 점등되고 공지의 부저를 울려주게 된다.If the door 2 is not closed even by the magnetic field of the electromagnets 4A and 4B, the output Q of the flip-flop F8 of the second counter (bar) becomes high after a predetermined time passes. ) Is operated again and the door 2 is still closed, the output Q of the flip-flop F9 becomes high at the timing of the next clock, and the alarm sound generating unit e operates to light up the LED D6. You will hear a known buzzer.

이러한 동가중에 도어(2)가 닫히면 스위치(3)가 온되어 계수기(가)(바)를 리세트시켜주게 되며, 상기한 바와같은 도어(2)의 흡인력(전자석(4A)(4B)의 자력)은 냉장고 도어패킹에 내장되어 있는 자석의 자력으로 도어(2)가 완전히 닫혀지지 않는 미세한 틈새발생시 이를 극복해주는 정도의 전자력에 의존하는 것이다.When the door 2 is closed during the same weight, the switch 3 is turned on to reset the counter (bar), and the suction force of the door 2 (electromagnets 4A and 4B) as described above. Magnetic force) is a magnetic force of a magnet embedded in the refrigerator door packing, and relies on an electromagnetic force of a degree that overcomes the minute gap when the door 2 is not completely closed.

또한 본 고안 장치는 위에서 냉장고 도어에만 국한하여 설명하였지만 밀폐를 필요로하는 가전기기나 장치를 예를들어 전자레인지등과 같은 장치에도 적용할 수 있는 것이다.In addition, the device of the present invention has been described above only in the refrigerator door, but may be applied to a device such as a microwave oven, for example, a home appliance or a device requiring sealing.

이상에서 설명된 바와같이 본 고안 장치에 의하여 냉장고 도어의 열려있는 상태를 그대로 방치하지 않고 닫을 수 있어 전력손실을 방지할 수 있음은 물론 냉장고내의 음식물의 손상을 방지할 수 있다.As described above, the device of the present invention can be closed without leaving the open state of the refrigerator door as it is, thereby preventing power loss and preventing damage to food in the refrigerator.
