The temperature variable chamber 14 is formed of a box-shaped case 16 having an open front surface, and the temperature variable chamber 14 is formed by a temperature variable chamber door 17 installed to be rotatable on the upper surface of the case 16. It is opened and closed. The temperature variable chamber 14 of the present embodiment is a space provided for storing food at a temperature different from that of the freezing chamber 11, and may be used as a rapid cooling chamber by supplying a large amount of cold air in some cases.

또한, 본 실시예에서는 냉동실(11) 내부에 박스형상으로 설치된 온도가변실을 예시하였으나, 온도가변실을 냉동실(11) 내부에 설치하지 않고 냉동실(11)과 격벽으로 분리한 독립공간으로 구성할 수도 있다.In addition, in the present exemplary embodiment, the temperature variable chamber installed in the box shape inside the freezing chamber 11 is illustrated, but the temperature variable chamber may be configured as an independent space separated from the freezing chamber 11 and the partition wall without being installed inside the freezing chamber 11. It may be.

냉동실(11)의 후방에는 고내공기를 열교환하는 냉동실 열교환기(18)가 마련되며, 냉동실 열교환기(18)의 아래에는 고내공기가 흡입되는 흡입구(19)가 형성되고, 냉동실 열교환기(18)의 상부에는 세로방향으로 길게 형성된 냉기토출덕트(21)가 마련된다. A freezer compartment heat exchanger 18 is provided at the rear of the freezer compartment 11 to heat exchange the air inside the freezer compartment, and a suction port 19 through which the inside air is sucked is formed below the freezer compartment heat exchanger 18, and the freezer compartment heat exchanger 18 is provided. The upper portion of the cold air discharge duct 21 is formed long in the longitudinal direction is provided.

도3에 도시한 바와 같이 도2에 도시한 냉장고는 냉동실 열교환기(18)를 통과하여 냉동실(11)로 공급되는 냉기를 안내하는 냉동실 유로(21)와, 냉동실 열교환기(18)를 통과하여 온도가변실(14)로 공급되는 냉기를 안내하는 온도가변실 유로(22)와, 냉동실 유로(21)로 강제송풍하는 냉동실용 송풍팬(23)과, 온도가변실 유로(22)로 강제송풍하는 온도가변실용 송풍팬(24)을 포함한다.As shown in FIG. 3, the refrigerator illustrated in FIG. 2 passes through a freezer compartment flow path 21 for guiding cold air supplied to the freezer compartment 11 through a freezer compartment heat exchanger 18 and a freezer compartment heat exchanger 18. Forced air blowing to the temperature variable chamber flow path 22 for guiding the cold air supplied to the temperature variable chamber 14, the freezing chamber blower fan 23 forcibly blown to the freezing chamber flow path 21, and the temperature variable chamber flow path 22. It includes a blower fan 24 for the temperature variable room.

냉동실 유로(21)와 온도가변실 유로(22)는 바이패스 유로(25)에 의해 서로 연결되며, 바이패스 유로(25)는 냉동실 유로(21)를 흐르는 냉기가 온도가변실 유로(22)로 용이하게 흐를 수 있도록 온도가변실(14) 방향으로 기울어지게 설치함이 바 람직하다.The freezer compartment flow path 21 and the temperature variable chamber flow path 22 are connected to each other by a bypass flow path 25, and the bypass flow path 25 is a cold air flowing through the freezer compartment flow path 21 to the temperature variable room flow path 22. It is preferable to install inclined in the direction of the temperature variable chamber 14 so that it can flow easily.

또한, 냉동실 유로(21)에는 냉동실 유로(21)를 흐르는 냉기량을 조절하는 냉동실 유로 댐퍼(27)가 설치되고, 바이패스 유로(25)에는 바이패스 유로(25)를 흐르는 냉기량을 조절하는 바이패스 유로 댐퍼(26)가 설치된다.In addition, the freezer compartment flow passage 21 is provided with a freezer compartment passage damper 27 for adjusting the amount of cold air flowing through the freezer compartment passage 21, and the bypass passage 25 controls the amount of cold air flowing through the bypass passage 25. The bypass flow path damper 26 is provided.

도4를 참조하여 도2 및 도3에 도시한 냉장고의 동작을 설명한다. 사용자가 일반운전을 선택하면 냉동실용 송풍팬(23) 및 온도가변실용 송풍팬(24)을 온 시킨다. 또한, 바이패스 유로댐퍼(26)를 회전시켜 바이패스 유로(25)를 폐쇄시킴으로써 냉동실 유로(21) 및 온도가변실 유로(22)가 분리되게 하고, 냉동실 유로댐퍼(27)는 회전시켜 냉동실 유로(21)가 개방되도록 한다. An operation of the refrigerator shown in FIGS. 2 and 3 will be described with reference to FIG. 4. When the user selects the normal operation, the freezing chamber blowing fan 23 and the temperature variable room blowing fan 24 are turned on. In addition, the bypass flow path damper 26 is rotated to close the bypass flow path 25 so that the freezer compartment flow path 21 and the temperature variable chamber flow path 22 are separated, and the freezer compartment flow damper 27 is rotated to freeze the chamber flow path. Allow 21 to open.

따라서 냉동실 열교환기(18)를 지난 냉기의 일부는 냉동실 유로(21)를 통해 냉동실(11)로 공급되고, 나머지 냉기는 온도가변실 유로(22)를 통해 온도가변실(14)로 유입되므로 온도가변실용 송풍팬(24)의 회전수를 조절하면 온도가변실(14)의 온도를 냉동실(11)과 다르게 할 수 있다.Therefore, a part of the cold air passing through the freezer compartment heat exchanger 18 is supplied to the freezer compartment 11 through the freezer compartment flow passage 21, and the remaining cold air flows into the temperature change chamber 14 through the temperature variable chamber passage 22. By adjusting the rotation speed of the variable chamber blowing fan 24, the temperature of the temperature variable chamber 14 may be different from that of the freezing chamber 11.

한편, 사용자가 급속냉각운전을 선택하면 온도가변실(14)에 다량의 냉기를 공급해야 하므로 냉동실용 송풍팬(23) 및 온도가변실용 송풍팬(23)을 온 시킨 상태에서 바이패스 유로댐퍼(26)를 회전시켜 바이패스 유로(25)가 개방되도록 하고, 냉동실 유로댐퍼(27)를 회전시켜 냉동실 유로(21)가 폐쇄되도록 한다.On the other hand, if the user selects the rapid cooling operation, a large amount of cold air must be supplied to the temperature variable chamber 14, so that the bypass flow damper (with the blower fan 23 and the temperature variable blower fan 23 turned on). The bypass passage 25 is opened by rotating 26, and the freezing chamber passage damper 27 is rotated to close the freezing chamber passage 21.

따라서 냉동실 열교환기(18)를 지나 냉동실(11)을 향해 흐르던 냉기는 냉동실 유로댐퍼(27)에 막혀 냉동실(11)로 유입되지 못하고 바이패스 유로(25)를 통해 온도가변실 유로(22)를 거쳐 온도가변실(14)로 유입된다. 또한, 냉동실 열교환기 (18)를 지난 나머지 냉기는 온도가변실 유로(22)를 거쳐 온도가변실로 유입된다. 이처럼 급속냉각운전에서는 열교환된 냉기가 모두 온도가변실(14)에 공급될 수 있도록 냉동실 유로댐퍼(27) 및 바이패스 유로댐퍼(26)를 제어한다.Therefore, the cold air flowing through the freezer compartment heat exchanger 18 toward the freezer compartment 11 is blocked by the freezer passage damper 27 and thus cannot be introduced into the freezer compartment 11, and thus the temperature variable chamber passage 22 is opened through the bypass passage 25. After entering the temperature variable chamber (14). In addition, the remaining cold air passing through the freezer compartment heat exchanger 18 is introduced into the temperature variable chamber via the temperature variable chamber flow path 22. As such, in the rapid cooling operation, the freezing chamber flow path damper 27 and the bypass flow path damper 26 are controlled to supply the heat exchanged cold air to the temperature variable chamber 14.

또한, 도4의 표에서는 나타내지 않았지만 온도가변실(14)이 과부하이면(즉, 온도가변실에 새롭게 투입된 음식물의 양이 많을 경우) 냉동실 유로댐퍼(27)를 개방한 상태에서 바이패스 유로댐퍼(26)를 적절히 열어 냉동실(11)로 흐르던 냉기의 일부만을 온도가변실(14)로 흐르게 함으로써 냉동실(11)의 온도에는 별다른 영향을 주지 않으면서 온도가변실(14)의 온도가 보다 더 신속하게 하강하도록 할 수 있다.In addition, although not shown in the table of FIG. 4, when the temperature variable chamber 14 is overloaded (that is, when the amount of food newly added to the temperature variable chamber is large), the bypass channel damper 27 is opened while the freezing chamber channel damper 27 is opened. By properly opening 26, only a part of the cold air flowing into the freezing chamber 11 flows into the temperature varying chamber 14 so that the temperature of the temperature varying chamber 14 becomes more rapid without affecting the temperature of the freezing chamber 11. You can make it descend.

이상에서 상세히 설명한 바와 같이, 본 발명은 일반운전에서는 냉동실 및 온도가변실에 냉기를 공급하지만 급속냉각운전에서는 열교환된 냉기를 온도가변실에만 공급함으로써 온도가변실의 온도를 신속하게 낮출 수 있다. As described in detail above, the present invention supplies cold air to the freezing chamber and the temperature varying chamber in a general operation, but in the rapid cooling operation, the temperature of the temperature varying chamber can be rapidly lowered by supplying only the heat-changing cold air to the temperature varying chamber.

또한, 운전상태에 따라 냉동실 및 온도가변실에 공급하는 냉기의 양을 다르게 함으로써 냉장고의 운전효율이 높일 수 있다.In addition, the operating efficiency of the refrigerator may be increased by varying the amount of cold air supplied to the freezer compartment and the temperature variable chamber according to the operating state.
