In the cold air duct (100) formed with the cold air suction hole 121 for sucking into the flow path 130, and the cold room cold air hole 122 for supplying the cold air of the flow path 130 to a refrigerating chamber (not shown), the cold air suction A freezing flow path 131 and a refrigeration flow path 132 are formed by separating the flow path 130 between the ball 121 and the refrigerating chamber cold air hole 122, and are frozen between the freezing flow path 131 and the refrigerating flow path 132. The cold passage 133 is formed to allow the cold air of the passage 131 to enter and exit the refrigerated passage 132.
그런 다음, 상기 냉동유로(131) 및 냉장유로(132)사이의 냉기통로(133)에 유로개폐장치(160)를 설치하는데, 먼저 냉기통로(133)의 전판(110) 후면에 벨로우즈형상의 개폐구(161)를 고정시킨다.Then, the flow path opening and closing device 160 is installed in the cold air passage 133 between the freezing flow passage 131 and the refrigeration flow passage 132.

한편, 냉각기(40)가 설치된 주냉기덕트(미도시)와 연통된 냉기흡입공(121)에 소정의 냉각팬(50)을 설치한다.Meanwhile, a predetermined cooling fan 50 is installed in the cold air suction hole 121 communicating with the main cold air duct (not shown) in which the cooler 40 is installed.
상기와 같이 구성된 냉기덕트(100)의 유로개폐장치(160)는 본 발명의 일 실시예에 불과하며, 예컨대 이의 구성 및 형상은 앞서 설명한 본 발명의 범위 내에서 얼마든지 그 변형이 가능하다.Flow opening and closing device 160 of the cold air duct 100 configured as described above is only one embodiment of the present invention, for example, the configuration and shape thereof may be modified within the scope of the present invention described above.
상술한 본 발명의 작용 및 효과를 상세히 설명한다.The operation and effects of the present invention described above will be described in detail.
상기 냉장실의 고내온도가 상승하게 되면, 제어부와 전기적으로 연결되어 냉장실 내부에 설치된 온도감지수단이 이를 감지하여 제어부에 신호를 보내고, 이 신호를 받은 제어부에서 구동수단(164)에 전기적신호를 출력하여 제3도의 (b)와 같이 냉기덕트(100)에 설치된 구동수단(164)이 동작하게 되고, 이의 작동에 따라 구동축(165)이 전진하면서 냉기통로(133)내에 설치된 개폐구(161)를 전진작동시키게 되는데, 이때 제어부의 제어에 따라 냉각팬(50)이 동작하여 냉각기로 공급하게 되고, 이에 공급된 냉기는 소정의 냉장덕트(미도시)를 따라 냉장실로 공급되어 고내를 소망하는 온도로 유지시켜 주게 된다.When the internal temperature of the refrigerating compartment is increased, the temperature sensing means installed in the refrigerating compartment is electrically connected to the control unit to detect the signal and sends a signal to the control unit, and the control unit receiving the signal outputs an electrical signal to the driving means 164. As shown in (b) of FIG. 3, the driving means 164 installed in the cold air duct 100 is operated. As the driving shaft 165 moves forward, the opening and closing hole 161 installed in the cold air passage 133 is moved forward. At this time, the cooling fan 50 operates under the control of the control unit to supply the cooler, and the supplied cold air is supplied to the refrigerating chamber along a predetermined refrigerating duct (not shown) to maintain the inside of the refrigerator at a desired temperature. Given.
그런 다음, 상기 냉장실의 온도가 적정온도를 유지하게 되면, 상기 냉장실 내부에 설치되어진 온도감지수단이 이를 감지하여 제어부에 전기적신호를 인가하고, 제어부는 제3도의 (a)와 같이 냉각팬(50)의 동작을 중지시킴과 동시에 하방으로 동작중인 구동수단(164)을 해제시키는데, 이 구동수단(164)이 해제되면 탄압된 스프링(167)의 복원력에 의해 상기 구동축(165)이 후퇴작동되므로서, 상기 냉기통로(133)가 개폐구(161)로 인하여 폐쇄되어 냉동유로(131)에서 냉장유로(132)로의 냉기공급이 중단된다.Then, when the temperature of the refrigerating compartment maintains the proper temperature, the temperature sensing means installed in the refrigerating compartment senses this and applies an electrical signal to the control unit, the control unit as shown in (a) of FIG. Stops the operation and releases the driving means 164 operating downward. When the driving means 164 is released, the driving shaft 165 is retracted by the restoring force of the spring 167 that is suppressed. The cold air passage 133 is closed due to the opening and closing port 161, and thus the supply of cold air from the freezing passage 131 to the refrigeration passage 132 is stopped.
그리고, 상기 냉동실의 온도가 적정온도 이상으로 상승하게 되면, 상기 냉동실 내부에 설치되어진 온도감지수단이 이를 감지하여 냉각팬(50)을 동작시켜 냉각기로부터 생성된 냉기를 냉동실냉기공(111)을 통해 냉동실로 공급하게 되는데, 이때 상기 구동수단(164)은 해제된 상태를 유지하므로 상기 냉동유로(131)에서 냉장유로(132)로의 냉기공급은 중단된다.Then, when the temperature of the freezer compartment rises above the proper temperature, the temperature sensing means installed in the freezer compartment detects this and operates the cooling fan 50 to operate the cold air generated from the cooler through the freezer compartment cold air 111. The supply means is supplied to the freezing compartment, in which case the driving means 164 is maintained in a released state, so the supply of cold air from the freezing passage 131 to the refrigerating passage 132 is stopped.
따라서, 본 발명은 상기 냉기덕트(100)의 냉장실냉기공(122)으로 공급되는 냉기를 제어하므로서 냉장실이 과냉되는 것을 방지함은 물론이고, 상기 냉기덕트(100)에 하나의 냉각팬(50)만 설치토록하여 이로 인한 소음 및 공진현상을 극소화시킨 효과가 있다.Therefore, the present invention prevents the refrigerating compartment from being overcooled by controlling the cold air supplied to the refrigerating chamber cold air holes 122 of the cold air duct 100, and has one cooling fan 50 in the cold air duct 100. It is possible to install only to minimize the noise and resonance phenomena caused by this.
