More particularly, the present invention relates to a refrigerator capable of forming an air curtain. More particularly, the present invention relates to an air curtain forming apparatus. It's about the refrigerator.

냉장고중 일부에는, 저장품의 출입을 위한 도어의 개방시, 비교적 고운다습한 외부의 공기가 냉장실내로 유입되는 것을 차단하도록 냉장실의 개구영역에 개구면에 거의 평행하게 공기가 토출되도록 하는 소위 에어커튼 형성장치가 마련되어 있다.Some of the refrigerators have a so-called air curtain that causes the air to be discharged almost parallel to the opening surface of the refrigerating compartment opening area so as to prevent the relatively cool and humid outside air from entering the refrigerating compartment when opening the door for entering and exiting the stored product. A forming apparatus is provided.

그런데, 이러한 에어커튼 형성 장치를 구비한 종래의 냉장고에 있어서는, 도어의 개방시에 에어커튼을 형성하고, 도어의 개구차단시 냉장실에 냉기가 공급될 수 있도록 냉기공급을 절환하는 밸브장치, 구동장치 및 일련의 기구적 전동메카니즘이 채용되게 된다. 이러한 장치들은 비교적 그 구조가 복잡하여 작동시 소음 및 진동을 유발시킬 수 있으며, 냉장고 내의 공간을 많이 점유하게 되어 용적효율을 저하시키는 문제점이 있다. 또한, 이러한 장치들은 비교적 고가이므로 제조비용 상승의 한 요인이 되고 있다.By the way, in the conventional refrigerator provided with such an air curtain forming apparatus, an air curtain is formed at the time of opening of a door, and the valve apparatus and drive device which switch supply of cold air so that cold air may be supplied to a refrigerating chamber at the time of opening of a door are blocked. And a series of mechanical transmission mechanisms are adopted. Such devices have a relatively complicated structure, which may cause noise and vibration during operation, and occupy a lot of space in the refrigerator, thereby lowering volumetric efficiency. In addition, these devices are relatively expensive, which contributes to the increase in manufacturing cost.

따라서, 본 발명의 목적은, 구조가 비교적 간단하며 제조비용의 저감 및 용적효율을 증대시킬 수 있을 뿐만 아니라, 소음 및 진동을 억제시킬 수 있는 에어커튼 형성장치를 갖는 냉장고를 제공하는 것이다.Accordingly, it is an object of the present invention to provide a refrigerator having an air curtain forming apparatus which is relatively simple in structure, can reduce manufacturing costs and increase volumetric efficiency, and can suppress noise and vibration.

(8) and a blowing pen 6 for blowing air are respectively provided.

냉기덕트(9)에는 냉기가 통과할 수 있도록 냉기통과공(10)이 상하방향을 따라 형성되어 있으며, 각 냉기통과공(10)영역에는 선반(11)이 설치되어 있다.The cold air duct 9 has a cold air passing hole 10 formed along the vertical direction so that cold air can pass therethrough, and a shelf 11 is provided in each cold air passing hole 10 area.

선반(11)은, 얇은 상자형상을 가지며, 일측에는 내부로 냉기가 유입될 수 있도록 냉기유입구(14)가 형성되어 있다. 각 선반(11)의 저부면에는 판면을 관통하여 복수의 냉기토출구(12)이 형성되어 있으며, 냉장실도어(5)의 인접영역 저부면에는 선반(11)의 저부연부를 따라 어에커튼토출구(13)가 형성되어 있다.Shelf 11 has a thin box shape, the cold air inlet 14 is formed on one side so that cold air flows into the inside. A plurality of cold air outlets 12 are formed in the bottom of each shelf 11 through the plate surface, and the air curtain discharge outlets are formed along the bottom edge of the shelf 11 at the bottom of the adjacent region of the refrigerating chamber door 5. 13) is formed.

한편, 각 선반(11)의 내부에는 판상의 개폐판(15)이 선반(11)의 저부면을 따라 슬라이딩 이동가능하도록 수용되어 있다. 각 개폐판(15)에는 선반(11)의 저부면에 형성된 냉기토출구(12)에 대응하여 냉기유통공(16)이 각각 형성되어 있다.On the other hand, the inside of each shelf 11, the plate-shaped opening and closing plate 15 is accommodated so as to be slidable along the bottom surface of the shelf (11). Cold openings 16 are formed in each opening and closing plate 15 corresponding to the cold air outlet 12 formed on the bottom surface of the shelf 11.

제6도는 제2도의 개폐판의 개략적인 제어블럭도이고, 제7도는 제1도의 냉장고의 도어개방시 냉기토출상태를 도시한 부분 종단면도이다. 이를 도면에 도시한 바와 같이, 제어프로그램이 내장된 마이컴 등을 포함한 제어부(25)에는 냉장실도어(5)의 개폐상태를 감지하는 도어개폐감지부(23)가 부속되어 있으머, 제어부(25)는 도어 개폐감지부(23)의 감지신호에 기초하여 개폐판(15)을 슬라이딩 구동시키는 개폐판슬라이딩구동부(27)를 제어하게 된다.FIG. 6 is a schematic control block diagram of the opening and closing plate of FIG. 2, and FIG. 7 is a partial longitudinal cross-sectional view showing a cold air discharge state when the door of the refrigerator of FIG. As shown in the figure, the control unit 25 including a microcomputer with a built-in control program is attached to the door opening and closing detection unit 23 for detecting the opening and closing state of the refrigerating chamber door 5, the control unit 25 The controller controls the opening and closing plate sliding driver 27 for slidingly driving the opening and closing plate 15 based on the detection signal of the door opening and closing detection unit 23.

여기서, 도어개폐감지부(23)는 냉장실도어(5)와 냉장실(3)의 전면개구연부의 접촉영역사이에 개재되도록 설치되어 냉장실도어(5)의 개방시 냉장실(3)의 내부조명을 위한 조명등을 점등시키는 도어개폐감지스위치를 이용하는 것이 바람직할 수 있다.Here, the door opening and closing detection unit 23 is installed so as to be interposed between the contact area of the front opening opening of the refrigerating chamber door 5 and the refrigerating chamber 3 so as to illuminate the inside of the refrigerating chamber 3 when the refrigerating chamber door 5 is opened. It may be desirable to use a door opening and closing switch for turning on a lamp.

그리고, 개폐판슬라이딩구동부(27)는 개폐판(15)의 일측에 랙지형부를 형성하고 랙치형부에 상대운동가능하도록 맞물림결합되는 피니언과, 냉장실도어의 개폐에 연동하여 피니언을 정역구동 시키는 구동 모터로 간단히 구성할 수 있다.In addition, the opening and closing plate sliding drive unit 27 forms a rack portion on one side of the opening and closing plate 15, and a drive motor for forward and backward driving the pinion in conjunction with the opening and closing of the refrigerating chamber door, and the pinion coupled to the rack tooth form to allow relative movement. It can be configured simply.

또한, 개폐판슬라이딩구동부(27)는 개폐판(15)의 슬라이딩 이동방향을 따라 돌출 및 철회가능한 솔레노이드를 개폐판(15)의 일측에 결합하고, 솔레노이드가 냉장실도어(5)의 개폐에 연동되도록 함으로써, 개폐판(15)이 냉기토출구 및 에어커튼 토출구를 슬라이딩 개폐하도록 구성할 수도 있다.In addition, the opening and closing plate sliding drive unit 27 couples the solenoid protruding and retractable along the sliding movement direction of the opening and closing plate 15 to one side of the opening and closing plate 15, so that the solenoid is linked to the opening and closing of the refrigerating chamber door (5). Thus, the opening and closing plate 15 may be configured to slide open and close the cold air discharge port and the air curtain discharge port.

이와 같은 구성에 의하여, 냉장실도어(5)의 개방상태가 도어개폐감지부(23)에 의해 감지되면, 제어부(25)는 개폐판슬라이딩구동부(27)를 제어하여 개폐판(15)이 선반(11)의 에어커튼토출구(13)가 개방되도록 한다. 그러면, 냉기유로(7)를 통하여 유동하는 공기는 각 선반(11)의 냉기유입구(14)를 통하여 선반(11)내로 유입되고, 선반(11)내로 유입된 공기는 선반(11)의 저부면에 형성된 에어커튼토출구(13)을 통하여 냉장실(3)의 전면개구면과 거의 평행하게 하향토출된다.By such a configuration, when the open state of the refrigerating chamber door 5 is detected by the door opening / closing detecting unit 23, the control unit 25 controls the opening / closing plate sliding drive unit 27 so that the opening / closing plate 15 is turned on the shelf ( The air curtain discharge port 13 of 11) is opened. Then, the air flowing through the cold air flow passage 7 is introduced into the shelf 11 through the cold air inlet 14 of each shelf 11, and the air introduced into the shelf 11 is the bottom surface of the shelf 11. The air curtain discharge port 13 formed in the discharge port is discharged downward in parallel with the front opening surface of the refrigerating chamber 3.

한편, 냉장실도어(5)가 냉장실(3)의 전면개구를 차단하게 되면, 제어부(25)는 개폐판슬라이딩구동부(27)를 제어하여 개폐판(15)의 냉기유통공(16)과 선반(11)의 저부면의 냉기토출구(12)가 상호 연통되도록 한다. 그러면, 에어커튼토출구(13)는 개폐판(15)에 의해 차단되며, 선반(11)내로 유입된 냉기는 각 냉기토출구(12)를 통하여 하향토출되게 한다.On the other hand, when the refrigerating chamber door 5 blocks the front opening of the refrigerating chamber 3, the control unit 25 controls the opening and closing plate sliding drive unit 27 to the cold air distribution hole 16 and the shelf of the opening and closing plate 15 ( The cold air outlet 12 of the bottom surface of 11) is to communicate with each other. Then, the air curtain discharge port 13 is blocked by the opening and closing plate 15, the cold air introduced into the shelf 11 is discharged downward through each cold air discharge port (12).

이상 설명한 바와 같이, 본 발명에 따르면, 구조가 비교적 간단하며 제조비용의 저감 및 용적효율을 증대시킬 수 있을 뿐만 아니라, 소음 및 진동을 억제시킬 수 있는 에어커튼 형성장치를 갖는 냉장고가 제공된다.As described above, according to the present invention, there is provided a refrigerator having an air curtain forming apparatus which is relatively simple in structure, can reduce manufacturing cost and increase volumetric efficiency, and can suppress noise and vibration.
