冷気が第２流路５６を通過する場合の吐出口である第２吹出し口６２は、上棚４０と背壁４２ａとの間に配置されている。また、第２吹出し口６２は背壁４２ａ上端に位置する。これにより、冷蔵ダクト３０から導入された冷気は、第２スリット６０を通過して下部ダクト３１の第２流路５６を通過し、下壁部５２ｄにより下方向の行く手を阻まれ、前方に誘導されて吹出し口６２を通り抜け、貯蔵容器４２内に直接導入される。すなわち、冷風は下部ダクト３１から直接に貯蔵容器４２内に導入される。   The 2nd blower outlet 62 which is a discharge port when cold air passes the 2nd flow path 56 is arrange | positioned between the upper shelf 40 and the back wall 42a. The second outlet 62 is located at the upper end of the back wall 42a. As a result, the cold air introduced from the refrigeration duct 30 passes through the second slit 60 and the second flow path 56 of the lower duct 31, and is prevented from going downward by the lower wall portion 52d and guided forward. Then, it passes through the outlet 62 and is directly introduced into the storage container 42. That is, the cold air is directly introduced into the storage container 42 from the lower duct 31.

実施形態の冷蔵庫１０によれば以下の効果を奏する。
冷蔵庫１０は流路上面部材３４を備えており、流路上面部材３４は流路切替機構３２を備えている。流路切替機構３２は、操作レバー３２ａ及びこれに一体的に構成され、第１スリット５８及び第２スリット６０の開閉を切り替え可能に構成された閉塞板３２ｂを備えている。閉塞板３２ｂは、貯蔵室１６ｃ奥壁から手前側に突出形成され、ユーザにより操作可能に配置された操作レバー３２ａを左右にスライドさせることにより、第１スリット５８を閉塞した状態と、第２スリット６０を閉塞した状態とを切り替え可能に構成されている。冷気の経路である下部ダクト３１の一部であって第１スリット５８を通過する第１流路５４は、冷気を貯蔵容器４２の外周に導入する。冷気の経路である下部ダクト３１の一部であって第２スリット６０を通過する第２流路５６は、冷気を直接、貯蔵容器４２の内部に導入する。この構成により、冷気を第１スリット５８及び第１吹出し口６１を通過させて貯蔵容器４２の外周に導入した場合には、貯蔵容器４２内をその外周から冷却することで貯蔵容器４２内の湿度を高く保つことができ、外周に結露が発生する場合には、結露の発生を抑制又は除去することができる。 The refrigerator 10 according to the embodiment has the following effects.
The refrigerator 10 includes a channel upper surface member 34, and the channel upper surface member 34 includes a channel switching mechanism 32. The flow path switching mechanism 32 includes an operation lever 32a and a closing plate 32b that is configured integrally with the operation lever 32a and that can switch between opening and closing of the first slit 58 and the second slit 60. The closing plate 32b is formed so as to protrude from the rear wall of the storage chamber 16c to the near side, and the operation lever 32a arranged to be operable by the user is slid left and right to close the first slit 58, and the second slit 60 is configured to be switchable. The first flow path 54 that is a part of the lower duct 31 that is the path of the cold air and passes through the first slit 58 introduces the cold air to the outer periphery of the storage container 42. The second flow path 56 that is a part of the lower duct 31 that is the path of the cold air and passes through the second slit 60 introduces the cold air directly into the storage container 42. With this configuration, when cold air is introduced into the outer periphery of the storage container 42 through the first slit 58 and the first outlet 61, the humidity in the storage container 42 is reduced by cooling the interior of the storage container 42 from the outer periphery. Can be kept high, and when condensation occurs on the outer periphery, the occurrence of condensation can be suppressed or eliminated.

また、高湿時において貯蔵容器４２の上面に位置する棚、すなわち上棚４０の結露が発生する場合は、操作レバー３２ａをスライドさせることにより、第１スリット５８を閉塞させ、第２スリット６０を開放させる状態に切り替え、貯蔵容器４２内に直接冷気を吹き込むことで貯蔵容器４２内部と外部の温度差が均衡となり、結露を解消することができる。これにより、貯蔵容器４２内に格納された例えば野菜を傷めることを抑制することが可能となる。   Further, when condensation occurs on the shelf located on the upper surface of the storage container 42 at the time of high humidity, that is, the upper shelf 40, the first slit 58 is closed and the second slit 60 is opened by sliding the operation lever 32a. By switching to the state to be performed and blowing cold air directly into the storage container 42, the temperature difference between the inside and the outside of the storage container 42 is balanced, and condensation can be eliminated. Thereby, it becomes possible to suppress damaging, for example, vegetables stored in the storage container 42.

また、上記のように、下部ダクト３１すなわち第１流路５４から、貯蔵容器４２に直接冷気を導入する状態と、下部ダクト３１すなわち第２流路５６から、貯蔵容器４２の外周に直接冷気を導入する状態を、ユーザにより切り替え可能とすることで、貯蔵容器４２内の温度調節や湿度調整を可能とし、さらに、貯蔵容器４２外周に発生した結露の除去または結露発生の抑制を図ることができる。   In addition, as described above, the cool air is directly introduced into the storage container 42 from the lower duct 31, that is, the first flow path 54, and the cool air is directly applied to the outer periphery of the storage container 42 from the lower duct 31, that is, the second flow path 56. By enabling the user to switch the state to be introduced, it is possible to adjust the temperature and humidity in the storage container 42, and further, it is possible to remove condensation generated on the outer periphery of the storage container 42 or to suppress the occurrence of condensation. .

貯蔵容器４２の上部に貯蔵室１６ｃの底部となる上棚４０が設けられている。また、上棚４０は貯蔵容器４２の上部入り口を覆う覆い部でもある。第２流路５６の下部ダクト３１からの吐出口である第２吹出し口６２は、上棚４０と貯蔵容器４２の背壁４２ａとの間に配置されている。貯蔵容器４２が上棚４０により蓋をされているため、冷気を貯蔵容器４２外周に通じた場合には、貯蔵容器４２内の湿度を高く保持可能となる。また、貯蔵容器４２内に冷気を導入する場合には、冷気が上棚４０に当たりやすくなり、上棚４０に結露が付着している場合には、これを効率的に除去することが可能となる。   An upper shelf 40 serving as the bottom of the storage chamber 16c is provided at the top of the storage container 42. The upper shelf 40 is also a cover that covers the upper entrance of the storage container 42. A second outlet 62, which is an outlet from the lower duct 31 of the second flow path 56, is disposed between the upper shelf 40 and the back wall 42 a of the storage container 42. Since the storage container 42 is covered with the upper shelf 40, when the cold air is passed to the outer periphery of the storage container 42, the humidity in the storage container 42 can be kept high. In addition, when cold air is introduced into the storage container 42, the cold air easily hits the upper shelf 40, and when condensation is attached to the upper shelf 40, it can be efficiently removed.

また、貯蔵室１６ｃの奥側には上棚４０に連続する形状となるように構成された流路上面部材３４の水平部３６が設けられている。これにより、貯蔵室１６ｃ内の貯蔵空間を大きくすることができ、貯蔵能力を向上させることができる。   Further, a horizontal portion 36 of a flow path upper surface member 34 configured to be continuous with the upper shelf 40 is provided on the back side of the storage chamber 16c. Thereby, the storage space in the storage chamber 16c can be enlarged, and a storage capacity can be improved.
