A cooling fan 25 is disposed in the back of the ice making chamber 4 or the freezing slide chamber 6 and circulates cold air generated by the cooler 20 in the refrigerator. A cooling chamber 42 composed of the cooling fan 25 and the cooler 20 is disposed behind the ice making chamber 4, the freezing slide chamber 6, and the freezing chamber 9.

風路は、製氷室４に冷気を供給するための製氷室吐出ダクト３４と、製氷室４から冷気を冷却器２０に戻す製氷室戻りダクト３５と、製氷室吐出ダクト３４と直結し冷蔵室７に冷気を送る冷蔵室吐出ダクト３８と、冷蔵室７に送られた冷気を野菜室８に戻すための冷蔵室戻りダクト３９と、野菜室８に送られた冷気を冷却器２０に戻すための野菜室戻りダクト４０から構成され、ファン装置２５の運転により、冷却器２０で生成された冷気が各々の風路より各貯蔵室に供給され庫内は冷却される。冷蔵室吐出ダクト３８内には、ダンパー装置４１が配設され冷蔵室７へ供給する冷気を調節し、冷蔵室７を所定の温度に保つ。 The air passage is directly connected to the ice making chamber discharge duct 34 for supplying cold air to the ice making chamber 4, the ice making chamber return duct 35 for returning the cold air from the ice making chamber 4 to the cooler 20, and the ice making chamber discharge duct 34. A cold room discharge duct 38 for sending cold air to the cold room, a cold room return duct 39 for returning the cold air sent to the cold room 7 to the vegetable room 8, and a cold room sent to the vegetable room 8 for returning the cold air to the cooler 20 Consists of a vegetable room return duct 40, and by operating the fan device 25, the cool air generated by the cooler 20 is supplied to each storage room from each air passage, and the interior is cooled.

The second embodiment of the present invention will be described below with reference to FIG. FIG. 3 is a front view of the heat insulation box of the refrigerator according to Embodiment 2 of the present invention.

図３に示すように、冷蔵室吐出ダクト３８は製氷室戻りダクト３５と直結しており、ダンパー装置４１は製氷室戻りダクト３５内に配設されている。冷蔵室７に冷気を送る場合は、ダンパー装置４１が閉じている場合、製氷室４内の冷気は冷蔵室吐出ダクト３８を通り冷蔵室７に供給される。また、ダンパー装置４１が開いている場合、製氷室４内の冷気は冷蔵室吐出ダクト３８内と製氷室戻りダクト３５内の圧力差により、製氷室戻りダクト３５から冷却器２０へ導かれ冷蔵室７へは流れない。 As shown in FIG. 3, the refrigerator discharge duct 38 is directly connected to the ice making chamber return duct 35, and the damper device 41 is disposed in the ice making chamber return duct 35. When sending cold air to the refrigerator compartment 7, if the damper device 41 is closed, the cold air in the ice making chamber 4 is supplied to the refrigerator compartment 7 through the refrigerator discharge duct 38. When the damper device 41 is open, the cold air in the ice making chamber 4 is guided from the ice making chamber return duct 35 to the cooler 20 due to the pressure difference between the refrigerator discharge duct 38 and the ice making chamber return duct 35. It does not flow to 7.

以上のように、本実施の形態においては、ダンパー装置４１は、冷蔵室吐出ダクト３８内の冷蔵温度帯と冷凍温度帯の境界ではなく、製氷室戻りダクト３５内の冷凍温度帯内に配設され、常時低温低湿の雰囲気に置かれるので、ダンパー装置４１の着霜による動作不良を防止することができる。 As described above, in the present embodiment, the damper device 41 is disposed not in the boundary between the refrigeration temperature zone and the refrigeration temperature zone in the refrigeration chamber discharge duct 38 but in the refrigeration temperature zone in the ice making chamber return duct 35. In addition, since it is always placed in a low-temperature and low-humidity atmosphere, it is possible to prevent malfunction of the damper device 41 due to frost formation.

Embodiment 3 of the present invention will be described below with reference to FIG. FIG. 4 is a front view of the heat insulating box of the refrigerator according to Embodiment 3 of the present invention.

図４に示すように、冷蔵室吐出ダクト３８内には、トラップ構造４３が構成されている。冷却ファン２５が運転を停止しているとき、冷蔵室７と製氷室４の圧力差により、冷蔵室吐出ダクト３８の冷蔵室７開口部から、冷蔵室吐出ダクト３８内に高湿度の空気が流入する。高湿度の空気は比重が重いためトラップ構造４３の右側下部まで到達するが、トラップ構造４３の左側上部は乗り越えられないため、冷蔵室７から製氷室４への空気の対流は抑制され、冷蔵室吐出ダクト３８内の着霜による冷蔵室７の不冷を防止することができる。 As shown in FIG. 4, a trap structure 43 is formed in the refrigerator compartment discharge duct 38. When the cooling fan 25 is not operating, high-humidity air flows into the refrigerating chamber discharge duct 38 from the opening of the refrigerating chamber discharge duct 38 due to the pressure difference between the refrigerating chamber 7 and the ice making chamber 4. To do. High-humidity air has a high specific gravity, so it reaches the lower right side of the trap structure 43. However, the upper left side of the trap structure 43 cannot get over, so the convection of air from the refrigerating room 7 to the ice making room 4 is suppressed, and the refrigerating room Non-cooling of the refrigerator compartment 7 due to frost in the discharge duct 38 can be prevented.

以下本発明の実施の形態４を、図５に基づいて説明する。図５は本発明の実施の形態４における冷蔵庫の断熱箱体の正面図である。 (Embodiment 4)
Embodiment 4 of the present invention will be described below with reference to FIG. FIG. 5 is a front view of the heat insulating box of the refrigerator according to Embodiment 4 of the present invention.

図５に示すように、冷蔵室吐出ダクト３８内には、冷蔵室ファン４４が配設されている。冷蔵室ファン４４は、ダンパー装置４１の状態と連動し、ダンパー装置４１が閉の状態のときに運転を行う。冷蔵室７側の風路は、冷却ファン２５→製氷室吐出ダクト３４→製氷室４→冷蔵室吐出ダクト３８→冷蔵室７→冷蔵室戻りダクト３９→野菜室８→野菜室戻りダクト４０→冷却器２０という非常に長く抵抗が大きいため、夏場の高温高湿条件でドア開閉等の負荷が大きく、冷却器２０が多量の霜で覆われるような場合、冷却ファン２５から冷蔵室７へ送風される冷気の流量が大幅に減少してしまうが、冷蔵室ファン４４の運転により風量の減少を抑え冷蔵室７を所定の温度に保つことが可能である。 As shown in FIG. 5, a cold room fan 44 is disposed in the cold room discharge duct 38. The refrigerator compartment fan 44 operates in conjunction with the state of the damper device 41 and operates when the damper device 41 is in a closed state. The air path on the side of the refrigerator compartment 7 is the cooling fan 25 → the ice making chamber discharge duct 34 → the ice making chamber 4 → the refrigerator compartment discharge duct 38 → the refrigerator compartment 7 → the refrigerator compartment return duct 39 → the vegetable compartment 8 → the vegetable compartment return duct 40 → the cooling. Since the resistance of the cooler 20 is very long and the load is high such as opening and closing of doors under high temperature and high humidity conditions in summer, the cooler 20 is blown from the cooling fan 25 to the refrigerator compartment 7 when covered with a large amount of frost. However, it is possible to keep the refrigerator compartment 7 at a predetermined temperature by suppressing the reduction of the air volume by operating the refrigerator compartment fan 44.
