도 2 및 도 3에 도시된 본 발명의 일 실시예에서는, 상기 유로제어장치(200)가 상기 제1냉기유로부(131)와 상기 바이패스안내부(141)가 연결되는 부위에 일단이 회동 가능하도록 고정되어 회동에 의해 상기 제1냉기유로부(131)와 상기 바이패스유로부(141)를 선택적으로 개방하도록 구비된다.2 and 3, one end of the flow path control device 200 is rotated to a portion where the first cold air flow passage part 131 and the bypass guide part 141 are connected to each other. It is fixed so that it is provided to selectively open the first cold air flow path 131 and the bypass flow path 141 by rotation.

즉 상기 유로제어장치(200)는 도 2에 도시된 바와 같이 제1냉기유로부(131)를 차단하여 바이패스유로부(140)로 냉기가 유동하도록 하거나, 도 3에 도시된 바와 같이 바이패스유로부(140)를 차단하여 제1냉기유로부(131)로 냉기가 유동하도록 한다.That is, the flow path control device 200 blocks the first cold air flow path unit 131 as shown in FIG. 2 to allow cold air to flow to the bypass flow path unit 140, or bypasses as shown in FIG. 3. By blocking the flow path part 140, the cold air flows to the first cold air flow path part 131.

이때 상기 유로제어장치(200)는 상기 제1냉기유로부(131)를 완전하게 차단하지 않고, 상기 유로제어장치(200)가 제1냉기유로부(131)를 차단할 때 상기 유로제어장치(200)의 단부가 상기 제1냉기유로부(131)와 소정 간격으로 이격된다.At this time, the flow path control device 200 does not completely block the first cold air flow path unit 131, and the flow path control device 200 when the flow path control device 200 blocks the first cold air flow path unit 131. The end of the) is spaced apart from the first cold air flow path 131 at a predetermined interval.

이에 따라 안내부(102)에 의해 안내되는 냉기 중 대부분은 바이패스안내부(141)로 안내되어 냉기홀(142)을 통해 저장실(30, 도 1 참조)로 공급되고, 상기 안내부(102)에 의해 안내되는 냉기 중 적은 부분은 유로제어장치(200)의 단부 쪽 간격을 통해 제1냉기유로부(131)로 유동한다.Accordingly, most of the cold air guided by the guide part 102 is guided to the bypass guide part 141 and is supplied to the storage compartment 30 (see FIG. 1) through the cold air hole 142, and the guide part 102. A small portion of the cold air guided by the flow to the first cold air flow path 131 through the gap toward the end of the flow path control device 200.

그리고 이때 제2냉기유로부(132)로는 냉기가 항상 유입되어 토출구(120)를 통해 냉각실(10, 도 1 참조)로 공급된다.In this case, cold air is always introduced into the second cold air flow passage part 132 and is supplied to the cooling chamber 10 (see FIG. 1) through the discharge port 120.

한편, 상기 유로제어장치(200)는 상기 바이패스유로부(140)를 차단할 때 상 기 유로제어장치(200)의 단부가 상기 바이패스안내부(141)의 입구의 일측과 소정 간격으로 이격된다.On the other hand, when the flow path control device 200 blocks the bypass flow path unit 140, an end portion of the flow path control device 200 is spaced apart from one side of an inlet of the bypass guide part 141 at a predetermined interval. .

이에 따라 안내부(102)에 의해 안내되는 냉기 중 대부분은 제1냉기유로부(131)와 제2냉기유로부(132)로 유입되어 토출구(120)를 통해 냉각실(10, 도 1 참조)로 공급되고, 상기 안내부(102)에 의해 안내되는 냉기 중 적은 부분은 유로제어장치(200)의 단부 쪽 간격을 통해 바이패스유로부(140)로 유동하여 저장실(30, 도 1 참조)로 공급된다.Accordingly, most of the cold air guided by the guide part 102 flows into the first cold air flow path part 131 and the second cold air flow path part 132 and passes through the discharge port 120 to the cooling chamber 10 (see FIG. 1). And a small portion of the cold air guided by the guide part 102 flows to the bypass flow path part 140 through the end side gap of the flow path control device 200 to the storage chamber 30 (see FIG. 1). Supplied.

이하 도 1 내지 도 3을 참조하여 본 발명에 따른 냉장고의 작용에 관하여 설명한다.Hereinafter, the operation of the refrigerator according to the present invention will be described with reference to FIGS. 1 to 3.

먼저 냉각실(10)을 가동시키는 경우 냉각기(21)를 가동하고 팬(101)을 돌려 냉기를 송풍한다. First, when the cooling chamber 10 is operated, the cooler 21 is operated and the fan 101 is turned to blow cold air.

이때 도 3에 도시된 바와 같이 유로제어장치(200)를 작동시켜 바이패스유로부(140)를 차단하도록 한다.In this case, as shown in FIG. 3, the flow path control device 200 is operated to block the bypass flow path 140.

팬(101)에 의해 송풍되는 냉기는 안내부(102)에 의해 안내되어 메인유로부(130, 제1냉기유로부(131) 및 제2냉기유로부(132))로 유동하여 각 토출구(120)를 통해 냉각실(10)로 공급된다.The cold air blown by the fan 101 is guided by the guide part 102 and flows to the main flow path part 130, the first cold air flow path part 131, and the second cold air flow path part 132 to discharge each outlet 120. It is supplied to the cooling chamber 10 through).

그리고 안내부(102)에 의해 안내되는 냉기 중 일부는 유로제어장치(200)의 단부 쪽의 간극을 통해 바이패스유로부(140)로 유동하여 바이패스안내부(141)에 의해 안내되어 냉기홀(142)을 통해 저장실(30) 쪽으로 공급된다.Some of the cold air guided by the guide part 102 flows to the bypass flow path part 140 through a gap between the end portions of the flow path control device 200 to be guided by the bypass guide part 141 to be cooled by the cold air hole. It is supplied toward the storage compartment 30 through 142.

한편, 저장실(30)에 급속 냉각이 필요한 피냉각체가 보관되는 경우 상기 저 장실(30)에 집중적인 냉기 공급이 필요하므로, 유로제어장치(200)를 작동시켜 제1냉기유로부(131)를 차단하도록 하고 바이패스유로부(140)를 개방하도록 한다(도 2 참조).On the other hand, when the to-be-cooled object which requires rapid cooling is stored in the storage chamber 30, since the intensive cold air supply is required in the storage chamber 30, the flow path control device 200 is operated to operate the first cold air flow passage part 131. Block and open the bypass flow path 140 (see Figure 2).

팬(101)에 의해 송풍되는 냉기는 안내부(102)에 의해 안내되어 바이패스안내부(141)로 유입되고 상기 바이패스안내부(141)로 유입된 냉기는 냉기홀(142)을 통해 저장실(30) 쪽으로 토출되어 집중적인 냉기 공급이 이루어진다.The cold air blown by the fan 101 is guided by the guide unit 102 and introduced into the bypass guide unit 141, and the cold air introduced into the bypass guide unit 141 is stored through the cold air hole 142. It is discharged toward 30, and intensive cold air supply is performed.

이 경우에도 제2냉기유로부(132)로는 계속적으로 냉기 공급이 이루어지므로 냉각실(10)에 냉기의 공급이 어느 정도 이루어진다.Even in this case, since the cool air is continuously supplied to the second cold air flow passage part 132, the cool air is supplied to the cooling chamber 10 to some extent.

한편, 도면 상으로는 도시되지 아니하였으나 상기 유로제어장치를 제어하여 냉각실 냉각 운전과 저장실 냉각 운전을 적절하게 제어할 수 있는 제어부를 더 포함하는 것이 바람직하다.On the other hand, although not shown in the drawings it is preferable to further include a control unit for controlling the flow path control device to properly control the cooling chamber cooling operation and the storage chamber cooling operation.

상기와 같은 특징을 갖는 본 발명에 따른 냉장고는 냉각실과 저장실에 대한 독립적 냉각 운전을 수행할 수 있을 뿐만 아니라 냉각실 냉각 운전을 위해 냉기를 제어하는 댐퍼와 저장실 냉각 운전을 위해 냉기를 제어하는 댐퍼를 각각 별도로 마련할 필요 없이 하나의 유로제어장치로써 냉기의 제어를 할 수 있어 제조비용을 낮출 수 있고 제어를 더욱 간단하게 할 수 있는 효과가 있다.The refrigerator according to the present invention having the above characteristics can perform independent cooling operations for the cooling chamber and the storage compartment, as well as a damper for controlling cold air for the cooling chamber cooling operation, and a damper for controlling cold air for the storage compartment cooling operation. It is possible to control the cold air with a single flow path control device without having to provide each separately, thereby reducing the manufacturing cost and making the control simpler.
