본 발명은 냉장고의 냉기공급덕트에 관한 것으로, 특히 하나의 송풍팬을 구비한 냉장고의 냉장실용 냉기공급덕트 입구측에 댐퍼를 설치하여 냉동실과 냉장실에 선택적으로 냉기를 공급하도록 한 냉장고의 냉기공급덕트에 관한 것이다.The present invention relates to a cold air supply duct of a refrigerator, and in particular, a cold air supply duct of a refrigerator provided with a damper on an inlet side of a cold air supply duct for a cold compartment of a refrigerator having one blower fan to selectively supply cold air to the freezer compartment and a cold compartment. It is about.

제1도에서 잘 보여지는 바와 같이, 종래 냉장고의 냉기공급덕트는 증발기(2)가 설치되어 있는 냉동실의 후측부에 냉기송풍팬(3)이 설치되어 있고, 냉장고(1)의 후벽부(4)에 소정 폭과 길이를 갖고 하방으로 냉장실(5)과 연통되게 형성되는 냉장실용 냉기공급덕트(6)가 형성되어 있고, 냉동실(7)에는 상기 냉동실(7)과 증발기(2) 사이에 설치되어 공간을 구획하는 구획판(8)의 소정위치에 형성되어 있는 냉기토출공(9)을 통하여 냉기를 공급하였고, 상기 냉장실용 냉기공급덕트(6)의 출구측에 수동댐퍼(10)를 설치하여 사용자가 선택적으로 냉장실(5)에 냉기의 공급을 차단할 수 있도록 하므로써 냉장실(5)을 선택적으로 사용할 수 있도록 하였다.As shown in FIG. 1, the cold air supply duct of the conventional refrigerator is provided with a cold air blowing fan 3 at the rear side of the freezer compartment in which the evaporator 2 is installed, and the rear wall 4 of the refrigerator 1 is provided. The cold air supply duct 6 for the refrigerating chamber is formed in a lower portion and has a predetermined width and length in communication with the refrigerating chamber 5. The freezing chamber 7 is installed between the freezing chamber 7 and the evaporator 2. And supplied cold air through a cold air discharge hole 9 formed at a predetermined position of the partition plate 8 for partitioning the space, and a passive damper 10 is installed at the outlet side of the cold air supply duct 6 for the refrigerating compartment. By allowing the user to selectively block the supply of cold air to the refrigerating chamber (5) it was to be able to selectively use the refrigerating chamber (5).

그런데, 이와 같은 종래의 냉기공급덕트는 원팬타입(one fan type)의 냉장고에 채용된 냉기송풍팬(3)의 송풍력으로 증발기(2)에서 발생되는 냉기를 상기 냉장실용 냉기공급덕트(6)와 상기 구획판(8)의 냉기토출공(9)을 통하여 냉장실 또는 냉동실로 강제유도하여 해당 고내를 냉각시키고 있기 때문에 수납식품이 많고 고내 온도변화에 민감하게 반응하는 식품들이 수납되는 냉장실만의 냉기공급을 차단하거나 공급할 수 있는 별도의 제어가 곤란하므로 냉각효율이 저하되는 단점을 안고 있었다.However, such a conventional cold air supply duct is the cold air generated in the evaporator (2) by the blowing force of the cold air blowing fan (3) employed in the one fan type (one fan type) refrigerator cold air supply duct (6) The cold air only in the refrigerating compartment in which the foods are stored and the foods that are sensitive to the change in the temperature are stored because the inside of the partition plate 8 is forced to the refrigerating chamber or the freezing chamber through the cold air discharge hole 9. It was difficult to control the separate supply that can cut off or supply, so the cooling efficiency had a disadvantage.

이러한 문제점을 감안하여, 본 발명은 증발기에 의해서 발생되는 냉기를 냉기송풍팬에 집중시켜 냉기송풍팬의 송풍력을 강화시키고, 아울러 냉장실용 냉기공급덕트의 입구측에 전자댐퍼를 설치하여 냉기의 경로를 선택적으로 변경할 수 있도록 함으로써 냉기의 손실을 최소화시키면서 냉동실의 냉각효율을 최대한 강화시킬 수 있는 냉장고의 냉기공급덕트를 제공코자 함에 그 목적이 있다.In view of these problems, the present invention concentrates the cold air generated by the evaporator in the cold air blowing fan to enhance the blowing force of the cold air blowing fan, and also installs an electronic damper at the inlet side of the cold air supply duct for the cold room, thereby providing a path of cold air. The purpose of the present invention is to provide a cold air supply duct of a refrigerator that can enhance the cooling efficiency of the freezer as much as possible while minimizing the loss of cold air.

The inlet of the duct 16 is formed in communication.

상기 냉장실용 냉기공급덕트(16)는 상기 냉장실용 냉기공급덕트(15)와 냉장실(17)이 연통되도록 냉장고의 일측 측벽을 따라 길이방향으로 길게 형성된다.The refrigerating compartment cold air supply duct 16 is formed to extend in the longitudinal direction along one side wall of the refrigerator so that the refrigerating compartment cold air supply duct 15 and the refrigerating compartment 17 communicate with each other.

또한, 냉동실용 냉기공급덕트(16)와 냉장실용 냉기공급덕트(16)가 연접하는 부위에는 솔레노이드 전자댐퍼(19)가 설치된다.In addition, the solenoid electromagnetic damper 19 is installed at a portion where the cold air supply duct 16 for the freezing compartment and the cold air supply duct 16 for the refrigerating compartment are connected to each other.

상기 전자댐퍼(19)는 플랩형식으로 냉기방향을 가이드하는 댐퍼부(20)와, 솔레노이드 밸브(21)와, 상기 솔레노이드 밸브(21)와 연동되어 회전되며 그 중심에 나사산이 형성된 작동공(23)을 가지며 그 외주에는 다수의 기어가 형성된 헤드부(22a)와, 상기 냉동실용 냉기공급덕트(15)의 일측 출구의 상측 내상(99)물 관통하여 그 일단은 상기 댐퍼부(20)에 힌지결합되고 그 타단은 상기 헤드부(22a)의 작동공(23)에 대응되게 나삽되어 전후진 가능하도록 설치되는 작동나사(22)로 구성된다.The electromagnetic damper 19 is rotated in conjunction with the damper portion 20 for guiding the cold air direction in the form of a flap, the solenoid valve 21, and the solenoid valve 21, and a screw thread formed at the center thereof. And a head portion 22a having a plurality of gears formed on the outer circumference thereof, and an upper inner portion 99 of one outlet of the cold air supply duct 15 for the freezer compartment, and one end of which is hinged to the damper portion 20. The other end thereof is coupled to the other end is composed of a working screw 22 is installed so as to be inserted back and forth to correspond to the operating hole 23 of the head portion (22a).

여기에서, 상기 헤드부(22a)는 내상(99)에 소정형태와 설치부(도시생략)를 두어 위치고정되면서 축중심인 상기 작동나사(22)가 동작가능하게 설치된다.Here, the head portion 22a has a predetermined shape and an installation portion (not shown) in the inner box 99, and the operating screw 22 which is axial center is operably installed.

상기 댐퍼부(20)는 평판형상으로서 상단부 소정위치에 힌지돌기(20a)를 갖고, 냉동실용 냉기공급덕트(15)와 냉장실용 냉기공급덕트(16)가 연통되게 연접되는 부위에 회동가능하게 힌지결합되며, 상기 댐퍼부(20)의 양면 테두리부에 패킹(20b)이 부착된다.The damper portion 20 has a hinge protrusion 20a at a predetermined position at the upper end in a flat plate shape, and is hinged to a portion where the cold air supply duct 15 for a freezer compartment and the cold air supply duct 16 for a cold compartment communicate with each other.

또한, 액츄에이터(21a)의 끝단에는 소정길이와 폭을 갖는 래크(21b)가 일체로 형성된다.Further, at the end of the actuator 21a, a rack 21b having a predetermined length and width is integrally formed.

그리고, 상기 작동나사(22)는 그 일단부가 상기 댐퍼부(20)의 힌지 돌기(20a)와 회동가능하게 힌지결합되고, 타단부는 헤드부(22a)에 나삽되어 상기 액츄에이터(21a)의 래크(21b)와 치합되어 작동되는 피니언 형상의 헤드부(22a)와 연동되어 그 작동공(23)의 좌우측에서 왕복직선운동을 하도록 된다.In addition, one end of the working screw 22 is hinged to the hinge protrusion 20a of the damper portion 20 so as to be rotatable, and the other end is screwed into the head portion 22a to rack the actuator 21a. It is interlocked with the pinion-shaped head portion 22a which is engaged with the 21b to make a reciprocating linear motion at the left and right sides of the operating hole 23.

또한, 상기 전자댐퍼(19)는 냉장고의 마이크로프로세서(이하 제어부라 한다.)에 전기적으로 연결된다.In addition, the electromagnetic damper 19 is electrically connected to a microprocessor (hereinafter, referred to as a control unit) of the refrigerator.

이하, 상기 구성에 따른 본 발명의 작용 및 효과를 구체적으로 설명하면 다음과 같다.Hereinafter, the operation and effects of the present invention according to the above configuration will be described in detail.

제2도 내지 제4도에 도시한 바와 같이, 증발기(11)에 의해서 발생되는 냉기는 냉기송풍팬(14)의 송풍력에 의해서 냉기 안내판(13)의 전면부를 따라 냉기송풍팬(14) 측으로 모여서 냉기토출공(13a)을 통하여 냉동실용 냉기공급덕트(15)로 강제 토출된다.As shown in FIG. 2 to FIG. 4, the cold air generated by the evaporator 11 is blown along the front part of the cold air guide plate 13 by the blowing force of the cold air blower fan 14 to the cold air blower fan 14 side. Collected by force is discharged to the cold air supply duct 15 for the freezing chamber through the cold air discharge hole (13a).

이때에, 만약 냉동실만으로 냉기공급이 이루어지도록 작동스위치(미도시)가 선택된 상태라면, 제어부로부터 송출된 신호에 따라 제어되는 솔레노이드 밸브(21)의 작동에 의해 상기 래크(21b)가 전진되게 되고, 이에 따라 헤드부(22a)가 원운동하게 되어 상기 작동나사(22)가 연동되면서 상기 댐퍼부(20)를 밀게 되어 냉장실용 냉기공급덕트(16)를 폐쇄하게 된다.At this time, if the operation switch (not shown) is selected so that the cold air is supplied only to the freezing chamber, the rack 21b is advanced by the operation of the solenoid valve 21 controlled according to the signal sent from the controller, Accordingly, the head portion 22a moves in a circular motion to push the damper portion 20 while the operation screw 22 is interlocked to close the cold air supply duct 16 for the refrigerating compartment.

따라서, 냉장실로의 냉기공급은 차단되게 되므로, 상기 냉동실용 냉기공급덕트(15) 내로 강제유입된 냉기는 양측으로 신장되게 형성되어 있는 냉동실용 냉기공급덕트(15)를 통과하여 구획판(12)의 냉기토출공(12a)을 통해 냉동실(10)로 공급된다.Therefore, since the supply of cold air to the refrigerating compartment is blocked, the cold air forced into the freezing air supply duct 15 for the freezing compartment passes through the freezing compartment cold air supply duct 15 which is formed to extend to both sides, and the partition plate 12 is provided. It is supplied to the freezing chamber 10 through the cold air discharge hole (12a).

반면에, 상기 냉동실(10)과 냉장실로 냉기가 동시에 공급되도록 작동스위치를 작동시키면, 상기 솔레노이드 밸브(21)가 통전되면서 액츄에이터(21a)가 전방으로 작동되면서 액츄에이터(21a)의 전단부에 일체로 형성되어 있는 래크(21b)와 치합되어 있는 헤드부(22a)가 원운동하게 되고, 이에 따라 상기 작동나사(22)가 후진되면서 댐퍼부(20)를 냉장실용 냉기공급덕트(16)의 입구로부터 회동시켜 일측 냉동실용 냉기공급덕트(15)를 폐쇄함으로써, 냉장실로의 냉기 공급이 이루어지게 된다.On the other hand, when the operation switch is operated so that cold air is simultaneously supplied to the freezing compartment 10 and the refrigerating compartment, the solenoid valve 21 is energized and the actuator 21a is operated forward to integrally integrate with the front end of the actuator 21a. The head portion 22a engaged with the formed rack 21b moves in a circular motion. As a result, the working screw 22 is retracted so that the damper portion 20 is moved from the inlet of the cold air supply duct 16 for the refrigerating chamber. By rotating and closing the cold air supply duct 15 for one side of the freezer compartment, the cold air is supplied to the refrigerating compartment.

뿐만 아니라, 타측의 개방된 냉동실용 냉기공급덕트를 통하여 냉동실로의 냉기공급도 동시에 이루어지게 된다.In addition, the cold air supply to the freezing compartment is also made at the same time through the freezing air supply duct for the other side of the freezing compartment.
