Description

냉장고의 부압 해소장치Negative pressure release device of refrigerator

본 발명은 냉장고의 부압 해소장치에 관한 것으로, 보다 상세하게는 냉장고의 도어 개폐후 고내로 유입된 외부의 더운 공기가 급속도로 수축되면서 고내에 부압이 발생된 상태에서 사용자가 도어를 개방하기 위해 접근하게 되면 이를 감지하여 미리 고내 부압을 해소시키도록 하여 도어 개방력을 향상시킨 냉장고의 부압 해소장치에 관한 것이다.The present invention relates to an apparatus for releasing a negative pressure of a refrigerator, and more particularly, a user approaches to open a door in a state in which a negative pressure is generated in a refrigerator while hot air flowing into the refrigerator rapidly contracts after opening and closing the door of the refrigerator. When it detects this to relieve the internal negative pressure in advance to the negative pressure release device of the refrigerator to improve the door opening force.

일반적으로, 고내에 수납물품을 보관하거나 취출하기 위하여 냉장고의 도어를 일정시간 동안 개방한 후 폐쇄하게 되면 고외부의 습하고 더운 다량의 공기가 고내로 급속유입되게 된다.In general, when the door of the refrigerator is opened and then closed for a predetermined time in order to store or take out items stored in the refrigerator, a large amount of humid and hot air from the outside is rapidly introduced into the refrigerator.

이렇게 고내로 유입된 외부공기는 차가운 고내 온도조건 때문에 급속히 냉각되어 그 부피가 수축되면서 순간적으로 외부 대기압보다 다소 낮은 상태의 기압(이하 "부압"이라 함)을 소정시간 동안 유지하게 된다.The external air introduced into the air is rapidly cooled due to the cold air temperature conditions, and the volume is contracted to maintain the air pressure (hereinafter referred to as "negative pressure") at a somewhat lower level than the external atmospheric pressure for a predetermined time.

따라서, 이와 같이 고내에 부압이 발생한 상태일 때에 냉장고도어를 개방하고자 한다면 강제적으로 상기 부압을 해소하지 않고서는 냉장고도어를 개방하기가 어렵게 된다.Therefore, if the refrigerator door is to be opened while the negative pressure is generated in the refrigerator, it is difficult to open the refrigerator door without forcibly removing the negative pressure.

즉, 도시된 도 1과 같이, 냉장고의 냉동실도어(20)와 냉장실도어(40) 내측 테두리에 자석(미도시)이 내장된 가스켓(미도시)이 본체(10)의 전면에 면접 밀착되면서 냉동실 및 냉장실을 밀폐시키면서 외기와 차단시킨다.That is, as shown in Figure 1, the freezer compartment 20 and the gasket (not shown) with a magnet (not shown) built in the inner edge of the refrigerator compartment door 40 of the refrigerator in close contact with the front of the main body 10, the freezer compartment And blocking the refrigerating chamber from outside air.

따라서, 도어(20)(40) 개폐후에 고내로 유입된 온기는 급속히 수축되면서 고외 대기압에 비해 상대적으로 낮은 음압이 순간적으로 걸리게 되어 차후 냉장고의 도어(20)(40)를 개방하고자 할 경우에는 상당히 힘들어 사용자로 하여금 많은 불편을 초래하게 된다.Therefore, the warm air introduced into the refrigerator after opening and closing the doors 20 and 40 is rapidly contracted, and relatively low sound pressure is momentarily taken compared to the atmospheric pressure outside the air, so that the doors 20 and 40 of the refrigerator are considerably opened later. It is difficult for the user to cause a lot of inconvenience.

However, a large capacity electromagnet had to be used to obtain a sufficient door opening force.

따라서, 냉장고의 고내로 급속유입된 외부온기가 수축되면서 순간적으로 발생하는 고내 부압현상을 효과적으로 방지함과 동시에 도어개방력을 향상시킬 수 있는 다른 방안들이 요청되기에 이르렀다.Therefore, other measures have been required to effectively prevent the high internal negative pressure phenomenon that occurs instantaneously as the external warm air rapidly flows into the refrigerator and improve the door opening force.

이하에서는, 본 발명에 따른 바람직한 몇가지 실시예를 첨부도면에 의거하여 보다 상세하게 설명한다.Hereinafter, some preferred embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 부압 해소장치가 구비된 냉장고의 일부 절개 사시도이고, 도 3은 본 발명에 따른 부압 해소장치가 구비된 냉장고의 설치상태를 나타내는 평단면도이다.2 is a partially cutaway perspective view of a refrigerator provided with a negative pressure releasing device according to the present invention, and FIG. 3 is a plan sectional view showing an installation state of the refrigerator equipped with a negative pressure releasing device according to the present invention.

도시와 같이, 냉장고의 냉장실도어(40) 내측 외테두리에는 냉장고의 본체 캐비넷(10)과 접촉되어 밀착되는 가스켓(52)이 설치된다.As shown in the drawing, a gasket 52 which is in close contact with the main cabinet 10 of the refrigerator is installed at an outer edge of the refrigerator compartment door 40 of the refrigerator.

따라서, 상기 가스켓(52)은 냉장실 내부로 공급된 냉기가 고외로 유출되는 것을 방지하여 고내에 수납된 수납물품이 신선하고 오래토록 보관될 수 있도록 하여 준다.Therefore, the gasket 52 prevents cold air supplied into the refrigerating chamber from leaking out of the refrigerator, so that the stored articles stored in the refrigerator can be kept fresh and long.

그리고, 본체(10)의 일측벽에는 외부와 연통되고 단열벽(54) 내측으로 요입되어 유통홈(58)이 형성된다.In addition, one side wall of the main body 10 communicates with the outside and is recessed into the heat insulation wall 54 to form a distribution groove 58.

상기 유통홈(58)은 외부와 연통되는 입구측이 넓고 내측으로 갈수로 좁아진 형상으로 형성되며 상기 본체(10)의 일측벽을 완전히 관통하지는 않는다.The distribution groove 58 is formed in a shape in which the inlet side communicating with the outside is wide and narrowed toward the inside and does not completely penetrate one side wall of the main body 10.

또한, 상기 유통홈(58)은 냉장실(R)이 형성된 위치에 형성되되 냉장고 전면과 근접하여 형성된다.In addition, the distribution groove 58 is formed at a location where the refrigerating chamber (R) is formed, but is formed close to the front of the refrigerator.

아울러, 상기 유통홈(58)의 선단측은 냉장실도어(40) 폐쇄시 가스켓(52)이 밀착되는 인접부위와 연통되는 연통관(56)이 연결된다.In addition, the front end side of the distribution groove 58 is connected to the communication tube 56 is in communication with the adjacent portion in close contact with the gasket 52 when the refrigerator compartment door 40 is closed.

따라서, 만약 외부공기가 상기 유통홈(58)으로 유입되게 되면 유입된 공기는 상기 가스켓(52)측으로 공급될 수 있도록 된 구조이다.Therefore, if the outside air is introduced into the distribution groove 58, the introduced air can be supplied to the gasket 52 side.

한편, 상기 유통홈(58)의 후단측에는 피니언(62)을 갖는 구동모터(60)가 설치된다.On the other hand, a drive motor 60 having a pinion 62 is installed at the rear end side of the distribution groove 58.

상기 구동모터(60)는 냉장고의 마이크로프로세서(이하 "제어부"라 함)와 전기적으로 연결되어 그 정회전 및 역회전이 구동제어되도록 설치된다.The drive motor 60 is electrically connected to a microprocessor (hereinafter, referred to as a “control unit”) of the refrigerator, and installed so that its forward and reverse rotations are drive controlled.

또한, 상기 유통홈(58) 속에는 상기 유통홈(58)의 외측 선단을 밀폐시키는 밀폐부재(66)를 구비한 래크(64)가 상기 피니언(62)에 치합되어 설치된다.In the distribution groove 58, a rack 64 having a sealing member 66 for sealing the outer end of the distribution groove 58 is fitted to the pinion 62.

뿐만 아니라, 상기 밀폐부재(66)가 밀착되는 상기 유통홈(58)의 선단측에는 도시하지 않은 씰링부재가 부착되어 있다.In addition, a sealing member (not shown) is attached to the front end side of the distribution groove 58 to which the sealing member 66 is in close contact.

따라서, 상기 제어부의 제어신호에 따라 상기 구동모터(60)의 피니언(62)에 치합된 래크(64)가 전후진되면서 상기 유통홈(58)의 선단측을 선택적으로 개폐하게 되어 외부공기의 유입을 단속하게 된다.Accordingly, the rack 64 engaged with the pinion 62 of the drive motor 60 is moved forward and backward according to the control signal of the controller to selectively open and close the front end side of the distribution groove 58 to inflow of external air. Will be cracked down.

그리고, 냉장고의 냉동실도어(20) 혹은 냉장실도어(40)의 전면측에는 센서(50)가 설치되는 바, 바람직하게는 상기 냉동실도어(20)의 하단 전면에 설치됨이 바람직하다.And, the sensor 50 is installed on the front side of the freezer compartment door 20 or the refrigerating compartment door 40 of the refrigerator, preferably, it is preferably installed on the lower front surface of the freezer compartment door 20.

상기 센서(50)는 열감지센서로써 상기 제어부와 전기적으로 연결설치된다.The sensor 50 is electrically connected to the controller as a heat sensor.

또한, 상기 센서(50)의 열감지범위는 사람의 체온을 포함하는 약 35 ∼ 38°정도임이 바람직하다.In addition, the heat detection range of the sensor 50 is preferably about 35 to 38 degrees including the human body temperature.

이러한 구성으로 이루어진 본 발명의 부압해소장치의 작동관계에 대해 도 4a 및 도 4b 를 참조하여 설명한다.The operating relationship of the negative pressure releasing device of the present invention having such a configuration will be described with reference to FIGS. 4A and 4B.

도면에 도시된 바와 같이, 부압발생여부와 상관없이 평상시에는 밀폐부재(66)가 유통홈(58)의 선단측을 밀폐시킨 상태로 유지된다.As shown in the figure, regardless of whether or not negative pressure is generated, the sealing member 66 is maintained in a state where the front end side of the distribution groove 58 is normally sealed.

따라서, 외기가 고내측으로 유입되지 못하게 된다.Therefore, the outside air does not flow into the interior.

그리고, 만약 부압이 발생된 상태에서 사용자가 냉장실도어(40)를 개방시키고자 본체(10)측으로 접근하게 되면 도 2에 도시되어 있는 센서(50)에 의해 사용자의 접근이 감지되고 그 감지신호를 입력받은 제어부는 구동모터(60)를 정회전시키게 된다.And, if the user approaches the main body 10 to open the refrigerating chamber door 40 in the state that the negative pressure is generated, the user's approach is detected by the sensor 50 shown in FIG. The input control unit rotates the driving motor 60 forward.

따라서, 상기 구동모터(60)의 회동에 따라 그 선단의 피니언(62)과 치합된 래크(64)가 상기 유통홈(58)의 후단측으로 후퇴되게 되고 이에 따라 밀폐부재(66)는 상기 유통홈(58)의 선단측을 개방하게 된다.Accordingly, the rack 64 meshed with the pinion 62 at the front end of the drive motor 60 is retracted to the rear end side of the distribution groove 58, and thus the sealing member 66 is disposed in the distribution groove. The tip side of 58 is opened.

동시에, 외기가 급속유입되면서 상기 유통홈(58)과 연통되면서 개방된 연통관(56)을 타고 본체(10) 전면에 밀착된 냉장실도어(40)의 가스켓(52)측으로 공급되게 된다.At the same time, the outdoor air is supplied to the gasket 52 side of the refrigerating chamber door 40 in close contact with the front surface of the main body 10 through the open communication tube 56 while being in communication with the distribution groove 58.

따라서, 고내 부압이 해소되게 되어 사용자가 도어를 용이하게 개방할 수 있게 된다.Therefore, the internal negative pressure is eliminated and the user can easily open the door.

그런 후에, 일정시간이 경과되게 되면 냉장고의 제어부는 상기 구동모터(60)에 제어신호를 송출하여 상기 구동모터(60)를 역회전시키게 된다.After that, when a predetermined time elapses, the control unit of the refrigerator sends a control signal to the drive motor 60 to rotate the drive motor 60 in reverse.

이에 따라, 피니언(62)에 치합된 래크(64)가 상기 유통홈(58)의 선단측으로 전진되면서 그 단부에 고정된 밀폐부재(66)는 상기 유통홈(58)의 선단측을 폐쇄하게 된다.Accordingly, as the rack 64 engaged with the pinion 62 is advanced to the front end side of the distribution groove 58, the sealing member 66 fixed at the end thereof closes the front end side of the distribution groove 58. .

이와 같은 과정을 사용자의 접근여부에 따라 냉장고의 제어부가 자동제어함으로써 고내 부압발생과 무관하게 사용자는 냉장실도어(40)를 매우 용이하게 개방할 수 있게 된다.The control of the refrigerator is automatically controlled according to whether the user accesses the above process so that the user can open the refrigerating chamber door 40 very easily regardless of the occurrence of high internal pressure.

이상에서 살펴 본 바와 같이, 본 발명은 냉장고의 본체 일측과 가스켓측을 연통시키고 이를 밀폐할 수 있는 밀폐부재를 구비함과 동시에 사용자의 접근상태를 감지하는 센서를 구비하여 이 센서의 감지신호에 따라 상기 밀폐부재를 전후진 시키는 구동수단을 구비함으로써 냉장고의 도어 개폐후 고내로 유입된 외부의 더운 공기가 급속도로 수축되면서 고내에 부압이 발생된 상태에서 사용자가 도어를 개방하기 위해 접근하게 되면 이를 감지하여 미리 고내 부압을 해소시키도록 하여 도어 개방력을 향상시키는 효과를 제공한다.As described above, the present invention is provided with a sensor for communicating a main body side and a gasket side of the refrigerator and sealing the same, and at the same time having a sensor for detecting a user's approaching state according to the detection signal of the sensor. The drive means for moving the sealing member forward and backward detects when the user approaches to open the door in a state where the negative pressure is generated inside the refrigerator while the hot air flowing into the refrigerator is rapidly contracted after opening and closing the door of the refrigerator. It is possible to solve the negative pressure in advance in advance to provide an effect of improving the door opening force.
