The drawer doors 19, 21, 23 and 25 are all guided by guide rails (not shown) of the refrigerator body 3 and slide back and forth.

図２は、図１における製氷室９、上冷凍室１１及び下冷凍室１３の内部を示す簡略化した正面図である。製氷室９と上冷凍室１１とは、上下方向に延びる縦隔壁２７によって左右に分割してあり、製氷室９及び上冷凍室１１と、下冷凍室１３とは、水平方向に延びる下部横隔壁２９によって上下に分割してある。 FIG. 2 is a simplified front view showing the inside of the ice making chamber 9, the upper freezing chamber 11 and the lower freezing chamber 13 in FIG. The ice making chamber 9 and the upper freezing chamber 11 are divided into left and right by a vertical partition wall extending in the vertical direction, and the ice making chamber 9 and the upper freezing chamber 11 and the lower freezing chamber 13 are divided into left and right by a vertical partition wall extending in the vertical direction. It is divided into upper and lower parts by 29.

図２に示すように、製氷室９、上冷凍室１１及び下冷凍室１３に対応する位置の冷蔵庫背面側には、エバカバー３１を配置してある。エバカバー３１は、中空であって内部空間が図３に示す冷気ダクト３２となっている。縦隔壁２７及び下部横隔壁２９の後壁３ａ側の端部は、後壁３ａまで達しておらず、エバカバー３１の後壁３ａと反対側の表面に略対応する位置にある。したがって、エバカバー３１は、冷蔵庫本体３の後壁３ａと、縦隔壁２７及び下部横隔壁２９との間に位置している。 As shown in FIG. 2, an EVA cover 31 is arranged on the back side of the refrigerator at positions corresponding to the ice making chamber 9, the upper freezing chamber 11, and the lower freezing chamber 13. The EVA cover 31 is hollow and has an internal space of the cold air duct 32 shown in FIG. The ends of the vertical partition wall 27 and the lower horizontal partition wall 29 on the rear wall 3a side do not reach the rear wall 3a and are located at positions substantially corresponding to the surface on the opposite side of the rear wall 3a of the EVA cover 31. Therefore, the EVA cover 31 is located between the rear wall 3a of the refrigerator body 3 and the vertical partition wall 27 and the lower horizontal partition wall 29.

図２に示すように、エバカバー３１は、下冷凍室１３の上部側の一部に対応する下冷凍室対応部３１ａと、上冷凍室１１の略全域に対応する上冷凍室対応部３１ｂと、製氷室９の縦隔壁２７近傍位置に対応する製氷室対応部３１ｃとを備えている。 As shown in FIG. 2, the EVA cover 31 includes a lower freezing chamber corresponding portion 31a corresponding to a part of the upper side of the lower freezing chamber 13, and an upper freezing chamber corresponding portion 31b corresponding to substantially the entire area of the upper freezing chamber 11. It is provided with an ice-making chamber corresponding portion 31c corresponding to a position near the vertical partition wall 27 of the ice-making chamber 9.

下冷凍室対応部３１ａに対応する位置の後壁３ａに、冷却器３３を取り付け、上冷凍室対応部３１ｂに対応する位置の後壁３ａに、冷気ファン３５を取り付けている。冷却器３３及び冷気ファン３５は、エバカバー３１の一部を切り欠くことによって、エバカバー３１の冷気ダクト３２内にそれぞれ露出する。冷気ファン３５は、エバカバー３１の外部の空気を冷気ダクト３２に導入し、冷却器３３によって冷却された冷気を、後述する冷気吹出口から製氷室９や下冷凍室１３に吹き出す。 A cooler 33 is attached to the rear wall 3a at a position corresponding to the lower freezing chamber corresponding portion 31a, and a cold air fan 35 is attached to the rear wall 3a at a position corresponding to the upper freezing chamber corresponding portion 31b. The cooler 33 and the cold air fan 35 are each exposed in the cold air duct 32 of the EVA cover 31 by cutting out a part of the EVA cover 31. The cold air fan 35 introduces the air outside the EVA cover 31 into the cold air duct 32, and blows the cold air cooled by the cooler 33 to the ice making chamber 9 and the lower freezing chamber 13 from the cold air outlet described later.

製氷室９には、製氷機３７及び、製氷機３７で製氷された氷を貯蔵する貯氷箱３９を収容している。貯氷箱３９は、図１、図３に示す引出扉２１を引き出すことで引出扉２１と一緒に引き出されるように、引出扉２１に支持されている。貯氷箱３９は、引出扉２１を閉じた状態において、前後方向（図３中で左右方向）でエバカバー３１と引出扉２１との間の略全域を占めるように配置される。 The ice making chamber 9 houses an ice making machine 37 and an ice storage box 39 for storing ice made by the ice making machine 37. The ice storage box 39 is supported by the drawer door 21 so that the drawer door 21 shown in FIGS. 1 and 3 can be pulled out together with the drawer door 21. The ice storage box 39 is arranged so as to occupy substantially the entire area between the EVA cover 31 and the drawer door 21 in the front-rear direction (left-right direction in FIG. 3) with the drawer door 21 closed.

製氷機３７は、製氷皿４１と、製氷皿４１に対しひねりを与えることにより変形させる駆動機構４３とを備えている。製氷皿４１がひねられるようにして変形することで、製氷された氷が製氷皿４１から離脱する。製氷皿４１は、図２に示すように、貯氷箱３９の上方で、かつ、図３に示すように、エバカバー３１に対応する製氷室９の奥側に位置しており、貯氷箱３９よりも後壁３ａに近い位置にある。より具体的には、製氷皿４１の冷蔵後前面側の前端部は、貯氷箱３９の冷蔵庫背面側の後端部よりも、後側（図３中で右側）に位置する。製氷皿４１は、図２に示す冷蔵庫正面から見た左右方向の長さが、図３に示す冷蔵庫側面から見た前後方向の長さよりも長い。 The ice machine 37 includes an ice tray 41 and a drive mechanism 43 that deforms the ice tray 41 by giving it a twist. By deforming the ice tray 41 so as to be twisted, the ice made ice is separated from the ice tray 41. The ice tray 41 is located above the ice storage box 39 as shown in FIG. 2 and behind the ice making chamber 9 corresponding to the EVA cover 31 as shown in FIG. 3, and is located above the ice storage box 39. It is located near the rear wall 3a. More specifically, the front end portion of the ice tray 41 on the front side after refrigeration is located on the rear side (right side in FIG. 3) of the rear end portion on the back side of the refrigerator of the ice storage box 39. The length of the ice tray 41 in the left-right direction when viewed from the front of the refrigerator shown in FIG. 2 is longer than the length in the front-rear direction when viewed from the side surface of the refrigerator shown in FIG.

駆動機構４３は、製氷皿４１を間にして縦隔壁２７と反対側の冷蔵庫本体３の側壁内面に取り付けている。製氷皿４１は、駆動機構４３と反対側の端部をエバカバー３１の製氷室対応部３１ｃに固定している。駆動機構４３は、例えば一定角度可能な電気モータで構成され、電気モータの一定角度回転によって、製氷皿４１を図２中で左右方向を軸心とする回転中心軸を中心として回転させる。ここでの駆動機構４３は、製氷皿４１を図３中で左回り方向に一定角度回転させる。 The drive mechanism 43 is attached to the inner surface of the side wall of the refrigerator body 3 on the opposite side of the vertical partition wall 27 with the ice tray 41 in between. The end of the ice tray 41 on the opposite side of the drive mechanism 43 is fixed to the ice making chamber corresponding portion 31c of the EVA cover 31. The drive mechanism 43 is composed of, for example, an electric motor capable of a constant angle, and the ice tray 41 is rotated about a rotation center axis centered on the left-right direction in FIG. 2 by the constant angle rotation of the electric motor. Here, the drive mechanism 43 rotates the ice tray 41 in the counterclockwise direction by a constant angle in FIG.

これにより、製氷皿４１は、ひねりが与えられることになって、製氷皿４１で製氷された氷が製氷皿４１から離脱する。製氷皿４１には、給水管４５を通じて水が供給される。給水管４５は、製氷室９と野菜室７とを分割する上部横隔壁４７を貫通しており、例えば野菜室７の底部に配置してある図示しない給水タンクに接続される。ここで、図３に示すように、駆動機構４３及び、駆動機構４３による製氷皿４１のひねりの中心軸は、貯氷箱３９の冷蔵庫背面側の後端部よりも後側（図３中で右側）に位置する。 As a result, the ice tray 41 is given a twist, and the ice produced by the ice tray 41 is separated from the ice tray 41. Water is supplied to the ice tray 41 through the water supply pipe 45. The water supply pipe 45 penetrates the upper horizontal partition wall 47 that divides the ice making chamber 9 and the vegetable chamber 7, and is connected to, for example, a water supply tank (not shown) arranged at the bottom of the vegetable chamber 7. Here, as shown in FIG. 3, the central axis of the drive mechanism 43 and the twist of the ice tray 41 by the drive mechanism 43 is on the rear side (right side in FIG. 3) of the ice storage box 39 on the rear side of the refrigerator. ).

製氷皿４１の下方には、氷案内部としての傾斜板４９を配置している。傾斜板４９は、冷蔵庫１の前面側（図３中で左側）が裏面側（図３中で右側）よりも上下方向位置が低くなるように傾斜している。傾斜板４９は、図２に示すように冷蔵庫１の正面から見て、左右方向の長さが、製氷皿４１における氷が製氷される部位の左右方向の長さよりもやや長く、貯氷箱３９の上部の開口部分の左右方向の長さよりやや短い。傾斜板４９は、例えば取付具５１によって後壁３ａに取り付けられる。 An inclined plate 49 as an ice guide portion is arranged below the ice tray 41. The inclined plate 49 is inclined so that the front side (left side in FIG. 3) of the refrigerator 1 is lower in the vertical direction than the back side (right side in FIG. 3). As shown in FIG. 2, the inclined plate 49 has a left-right length when viewed from the front of the refrigerator 1, which is slightly longer than the left-right length of the ice-making portion of the ice tray 41. Slightly shorter than the left-right length of the upper opening. The inclined plate 49 is attached to the rear wall 3a by, for example, a fixture 51.

図４は、製氷室９及び上冷凍室１１の平面図であり、エバカバー３１の製氷室対応部３１ｃに、第１冷気吹出口３１ｃ１及び第２冷気吹出口３１ｃ２を形成している。第１冷気吹出口３１ｃ１は、図２、図５に示すように、製氷室対応部３１ｃの上冷凍室対応部３１ｂと反対側の端面の上部に開口し、貯氷箱３９の冷蔵庫背面側の後端部よりも後側（図５中で左側）に位置する。第１冷気吹出口３１ｃ１は、製氷皿４１よりも上部に位置し、吹出した冷気が製氷皿４１に供給された水の表面に直接触れるようにしている。 FIG. 4 is a plan view of the ice making chamber 9 and the upper freezing chamber 11, and the first cold air outlet 31c1 and the second cold air outlet 31c2 are formed in the ice making chamber corresponding portion 31c of the EVA cover 31. As shown in FIGS. 2 and 5, the first cold air outlet 31c1 opens at the upper part of the end surface opposite to the upper freezing chamber corresponding portion 31b of the ice making chamber corresponding portion 31c, and is behind the refrigerator back side of the ice storage box 39. It is located on the posterior side (left side in FIG. 5) of the end. The first cold air outlet 31c1 is located above the ice tray 41 so that the blown cold air comes into direct contact with the surface of the water supplied to the ice tray 41.

すなわち、第１冷気吹出口３１ｃ１から吹き出された冷気は、図２、図４の矢印Ｃ１で示すように、製氷皿４１に供給された水の表面（製氷皿４１の上面）に沿って駆動機構４３に向けて流れる。なお、第１冷気吹出口３１ｃ１は、製氷皿４１の側部に対向する位置でもよい。この場合、第１冷気吹出口３１ｃ１から吹き出された冷気は、製氷皿４１の側部に衝突する。 That is, as shown by the arrows C1 in FIGS. 2 and 4, the cold air blown out from the first cold air outlet 31c1 is driven along the surface of the water supplied to the ice tray 41 (the upper surface of the ice tray 41). It flows toward 43. The first cold air outlet 31c1 may be located at a position facing the side portion of the ice tray 41. In this case, the cold air blown out from the first cold air outlet 31c1 collides with the side portion of the ice tray 41.

第２冷気吹出口３１ｃ２は、図２、図４、図５に示すように、製氷室対応部３１ｃの冷蔵庫前面側の表面に開口している。第２冷気吹出口３１ｃ２は、図５に示すように、上下方向位置が第１冷気吹出口３１ｃ１と略同等の上部に位置している。第２冷気吹出口３１ｃ２から吹き出された冷気は、製氷室９内の冷蔵庫前面側に向けて流れ、一部は貯氷箱３９に向けて流れる。なお、第２冷気吹出口３１ｃ２の位置は、上記した位置に限ることはない。例えば、図４において製氷室対応部３１ｃの冷蔵庫前面側の角部でもよく、図５における位置よりも下方でもよい。 As shown in FIGS. 2, 4, and 5, the second cold air outlet 31c2 is open on the surface of the ice making chamber corresponding portion 31c on the front side of the refrigerator. As shown in FIG. 5, the second cold air outlet 31c2 is located at an upper portion having a vertical position substantially equivalent to that of the first cold air outlet 31c1. The cold air blown out from the second cold air outlet 31c2 flows toward the front side of the refrigerator in the ice making chamber 9, and a part of the cold air flows toward the ice storage box 39. The position of the second cold air outlet 31c2 is not limited to the above-mentioned position. For example, in FIG. 4, the corner portion of the ice making chamber corresponding portion 31c on the front surface side of the refrigerator may be used, or may be below the position in FIG.

図２に示すように、エバカバー３１は、下冷凍室対応部３１ａの冷却器３３より上方位置に、下冷凍室１３に開口する第３冷気吹出口３１ｃ３を設けている。第３冷気吹出口３１ｃ３から吹き出された冷気によって、下冷凍室１３が冷却される。第３冷気吹出口３１ｃ３についても、上位した位置に限定されるものではない。なお、図示していないが、上冷凍室１１に冷気を吹き出す冷気吹出口を上冷凍室対応部３１ｂに設けてもよい。 As shown in FIG. 2, the EVA cover 31 is provided with a third cold air outlet 31c3 that opens into the lower freezing chamber 13 at a position above the cooler 33 of the lower freezing chamber corresponding portion 31a. The lower freezing chamber 13 is cooled by the cold air blown out from the third cold air outlet 31c3. The third cold air outlet 31c3 is also not limited to a higher position. Although not shown, a cold air outlet for blowing cold air into the upper freezing chamber 11 may be provided in the upper freezing chamber corresponding portion 31b.

本実施形態の冷蔵庫１は、製氷室９での製氷を中止しているときに、製氷皿４１で製造された氷以外の他の貯蔵物を貯蔵可能な温度に調整する温度制御部を備えている。この場合、例えば、第１冷気吹出口３１ｃ１及び第２冷気吹出口３１ｃ２から冷気が吹き出さないようにしたうえで、冷蔵室５や野菜室７に送り込む冷気を製氷室９に送り込むようにすればよい。 The refrigerator 1 of the present embodiment includes a temperature control unit that adjusts the temperature other than the ice produced in the ice tray 41 to a storable temperature when the ice making in the ice making chamber 9 is stopped. There is. In this case, for example, the cold air sent to the refrigerating room 5 and the vegetable room 7 may be sent to the ice making room 9 after preventing the cold air from blowing out from the first cold air outlet 31c1 and the second cold air outlet 31c2. good.

次に、本実施形態の作用効果を説明する。 Next, the action and effect of this embodiment will be described.

本実施形態は、冷蔵庫本体３に設けられる製氷室９と、製氷室９内の奥側に設けられ、冷気を製氷室９内に吹き出す冷気ダクト３２と、冷気ダクト３２から吹き出された冷気を受けてあらかじめ供給されている水が凍結して製氷される製氷皿４１と、製氷室９内に設けられ、製氷皿４１で製造された氷を貯蔵する貯氷箱３９と、を有する。製氷皿４１は、貯氷箱３９の上方かつ奥側で冷気ダクト３２に対応する位置に設けられている。 In this embodiment, the ice making chamber 9 provided in the refrigerator main body 3, the cold air duct 32 provided on the inner side of the ice making chamber 9 and blowing cold air into the ice making chamber 9, and the cold air blown out from the cold air duct 32 are received. It has an ice tray 41 in which the water previously supplied is frozen to make ice, and an ice storage box 39 provided in the ice making chamber 9 for storing the ice produced in the ice tray 41. The ice tray 41 is provided at a position corresponding to the cold air duct 32 above and behind the ice storage box 39.

この場合、製氷皿４１が貯氷箱３９よりも冷蔵庫１の奥側に位置しているため、貯氷箱３９の上方の空間がより広く確保されている。このため、製氷皿４１を取り外すことなく、貯氷箱３９を配置するスペースを冷凍室として利用しやすくなる。また、冷蔵庫１が、製氷室９での製氷を中止しているときに、氷以外の他の貯蔵物を貯蔵可能な温度に調整する温度制御部を備えることで、製氷室９を冷蔵室や野菜室として利用できる。 In this case, since the ice tray 41 is located behind the refrigerator 1 with respect to the ice storage box 39, a wider space above the ice storage box 39 is secured. Therefore, the space for arranging the ice storage box 39 can be easily used as a freezing chamber without removing the ice tray 41. Further, the refrigerator 1 is provided with a temperature control unit that adjusts the temperature other than ice to a storage temperature when the ice making in the ice making chamber 9 is stopped, so that the ice making chamber 9 can be made into a refrigerating chamber or a refrigerating chamber. It can be used as a vegetable room.

本実施形態は、製氷皿４１が、冷蔵庫正面から見て、左右方向の長さが前後方向の長さよりも長い。これにより、製氷皿４１よりも手前側の製氷室９のスペースを、前後方向の長さが左右方向の長さよりも長い場合に比較して、より広くすることができる。 In this embodiment, the ice tray 41 has a length in the left-right direction longer than a length in the front-rear direction when viewed from the front of the refrigerator. As a result, the space of the ice making chamber 9 on the front side of the ice tray 41 can be made wider than the case where the length in the front-rear direction is longer than the length in the left-right direction.

本実施形態は、製氷皿４１が、冷蔵庫正面から見て製氷室対応部３１ｃに対応する冷気ダクト３２の左右方向の側方に配置され、冷気ダクト３２の第１冷気吹出口３１ｃ１は、製氷皿４１に対向する側に設けられている。このため、第１冷気吹出口３１ｃ１から吹き出す冷気を、製氷皿４１に向かわせるための屈曲したダクトを設ける必要がなく、構造の簡素化を達成できる。 In the present embodiment, the ice tray 41 is arranged on the left-right side of the cold air duct 32 corresponding to the ice making chamber corresponding portion 31c when viewed from the front of the refrigerator, and the first cold air outlet 31c1 of the cold air duct 32 is an ice tray. It is provided on the side facing the 41. Therefore, it is not necessary to provide a bent duct for directing the cold air blown out from the first cold air outlet 31c1 toward the ice tray 41, and the structure can be simplified.

本実施形態は、第１冷気吹出口３１ｃ１が、製氷皿４１に対し、上下方向の位置関係で同等または上方に位置している。この場合、製氷皿４１の底部に製氷センサを取り付けたときに、冷気が製氷センサに直接当たるのを抑制できる。製氷センサは、製氷皿４１での製氷が完了したことを検知する温度センサである。このため、冷気が製氷センサに直接当たることによる誤検知を抑制できる。 In the present embodiment, the first cold air outlet 31c1 is located equal to or above the ice tray 41 in the vertical positional relationship. In this case, when the ice making sensor is attached to the bottom of the ice making dish 41, it is possible to prevent the cold air from directly hitting the ice making sensor. The ice making sensor is a temperature sensor that detects that the ice making in the ice making dish 41 is completed. Therefore, it is possible to suppress erroneous detection due to the cold air directly hitting the ice making sensor.

本実施形態は、冷気ダクト３２が、貯氷箱３９側に向けて冷気を吹き出す第２冷気吹出口３１ｃ２を備えている。このため、製氷室９内の温度分布をより均一化することができる。 In the present embodiment, the cold air duct 32 includes a second cold air outlet 31c2 that blows cold air toward the ice storage box 39 side. Therefore, the temperature distribution in the ice making chamber 9 can be made more uniform.

本実施形態は、製氷皿４１に対しひねりを与えることにより変形させて氷を離脱させる駆動機構４３が製氷皿４１に取り付けられている。製氷皿４１が、製氷室対応部３１ｃに対応する冷気ダクト３２側に位置し、駆動機構４３が、製氷皿４１を間にして製氷室対応部３１ｃに対応する冷気ダクト３２と反対側に位置している。この場合、製氷室対応部３１ｃに設けてある第１冷気吹出口３１ｃ１を、駆動機構４３が邪魔になることなく、製氷皿４１に容易に指向させることができる。 In this embodiment, a drive mechanism 43 for deforming the ice tray 41 by giving a twist to release the ice is attached to the ice tray 41. The ice tray 41 is located on the cold air duct 32 side corresponding to the ice making chamber corresponding portion 31c, and the drive mechanism 43 is located on the opposite side of the cold air duct 32 corresponding to the ice making chamber corresponding portion 31c with the ice tray 41 in between. ing. In this case, the first cold air outlet 31c1 provided in the ice making chamber corresponding portion 31c can be easily directed to the ice tray 41 without the drive mechanism 43 getting in the way.

本実施形態は、駆動機構４３による製氷皿４１のひねりの中心軸線は、冷蔵庫前面側から見て左右方向に延在している。駆動機構４３は、製氷皿４１が上記中心軸線を中心としてひねられることによって、製氷皿４１の開口側が貯氷箱３９に指向するように駆動する。この場合、製氷皿４１は、図３中で左回り方向に回転して上部開口側が貯氷箱３９に向くことになり、製氷皿４１から離脱した氷が貯氷箱３９に向けて効率よく落下する。 In this embodiment, the central axis of the twist of the ice tray 41 by the drive mechanism 43 extends in the left-right direction when viewed from the front side of the refrigerator. The drive mechanism 43 drives the ice tray 41 so that the opening side of the ice tray 41 faces the ice storage box 39 by twisting the ice tray 41 around the central axis. In this case, the ice tray 41 rotates counterclockwise in FIG. 3 so that the upper opening side faces the ice storage box 39, and the ice separated from the ice tray 41 efficiently falls toward the ice storage box 39.

本実施形態は、製氷皿４１の下方に、製氷皿４１で製造された氷を貯氷箱３９に向けて案内する傾斜板４９が設けられている。このため、製氷皿４１から離脱した氷が、傾斜板４９に案内されて貯氷箱３９に効率よく落下する。 In this embodiment, an inclined plate 49 for guiding the ice produced in the ice tray 41 toward the ice storage box 39 is provided below the ice tray 41. Therefore, the ice separated from the ice tray 41 is guided by the inclined plate 49 and efficiently falls into the ice storage box 39.

［第２の実施形態］
図６は、第２の実施形態を示す、図２に対応する正面図である。第２の実施形態は、第１の実施形態に対し、製氷機３７の左右方向の向きが逆になっている。すなわち、図６に示す製氷機３７は、駆動機構４３が縦隔壁２７側に位置し、製氷皿４１が駆動機構４３を間にして縦隔壁２７と反対側に位置している。 [Second Embodiment]
FIG. 6 is a front view corresponding to FIG. 2, showing the second embodiment. In the second embodiment, the direction of the ice machine 37 in the left-right direction is opposite to that in the first embodiment. That is, in the ice making machine 37 shown in FIG. 6, the drive mechanism 43 is located on the vertical partition wall side 27, and the ice tray 41 is located on the opposite side of the vertical partition wall 27 with the drive mechanism 43 in between.

駆動機構４３は、製氷室対応部３１ｃの第１冷気吹出口３１ｃ１を避けた位置で、かつ、エバカバー３１の内部に取り付けている。一方、製氷皿４１は、縦隔壁２７と反対側の冷蔵庫本体３の側壁内面に支持具５７を介して取り付けている。 The drive mechanism 43 is attached at a position avoiding the first cold air outlet 31c1 of the ice making chamber corresponding portion 31c and inside the EVA cover 31.

By locating the drive mechanism 43 at a position corresponding to the vertical partition wall 27, the EVA cover 31 has a shape in which the ice making chamber corresponding portion 31c shown in FIGS. 2 and 6 is not formed. In this case, the drive mechanism 43 is attached to the end portion on the back side of the paper surface in FIG. 7 of the vertical partition wall 27, or is attached to the upper freezing chamber corresponding portion 31b of the EVA cover 31. When it is attached to the upper freezing chamber corresponding portion 31b, the position is such that the first cold air outlet 31c1 is avoided.

製氷室対応部３１ｃが形成されていないので、製氷室９に冷気を吹き出す第２冷気吹出口３１ｃ２は、例えば製氷機３７より下方位置で、上冷凍室対応部３１ｂの製氷室９側の端部に形成する。また、上冷凍室対応部３１ｂを図７に示す位置よりも縦隔壁２７に対応する位置まで左側に突出させることで、駆動機構４３を第２の実施形態のようにエバカバー３１の内部に取り付けることもできる。 Since the ice making chamber corresponding portion 31c is not formed, the second cold air outlet 31c2 that blows cold air into the ice making chamber 9 is located below the ice making machine 37, for example, at the end of the upper freezing chamber corresponding portion 31b on the ice making chamber 9 side. Form to. Further, the drive mechanism 43 is attached to the inside of the EVA cover 31 as in the second embodiment by projecting the upper freezing chamber corresponding portion 31b to the left side from the position shown in FIG. 7 to the position corresponding to the vertical partition wall 27.

第３の実施形態は、駆動機構４３が、冷気ダクト３２の第１冷気吹出口３１ｃ１側に位置し、かつ、冷蔵庫前面から見て製氷室９に対し左右方向に隣接する上冷凍室１１との間の縦隔壁２７に対応する位置に配置されている。製氷皿４１は、駆動機構４３を間にして冷気ダクト３２の第１冷気吹出口３１ｃ１と反対側に位置している。この場合、縦隔壁２７に対応する位置も製氷機３７の配置に利用でき、製氷機３７を配置する際の自由度が向上する。 In the third embodiment, the drive mechanism 43 is located on the first cold air outlet 31c1 side of the cold air duct 32, and has an upper freezing chamber 11 adjacent to the ice making chamber 9 in the left-right direction when viewed from the front of the refrigerator. It is arranged at a position corresponding to the vertical partition wall 27 between them. The ice tray 41 is located on the opposite side of the cold air duct 32 from the first cold air outlet 31c1 with the drive mechanism 43 in between. In this case, the position corresponding to the vertical partition wall 27 can also be used for arranging the ice maker 37, and the degree of freedom when arranging the ice maker 37 is improved.

［第４の実施形態］
図８は、第４の実施形態を示す、図３に対応する断面図である。第４の実施形態は、第１の実施形態に対し貯氷箱３９の底部の形状が異なる。具体的には、貯氷箱３９は、冷蔵庫１の前後方向（図８中で左右方向）の略中間位置から後方側の底部にかけて傾斜面３９ａを形成している。傾斜面３９ａは、冷蔵庫前面側（図８中で左側）から裏面側（図８中で右側）に向けて上下方向の高さが徐々に高くなっている。なお、傾斜面３９ａは、貯氷箱３９の底部の前後方向の全域に設けてもよい。 [Fourth Embodiment]
FIG. 8 is a cross-sectional view corresponding to FIG. 3, showing a fourth embodiment. The fourth embodiment has a different shape of the bottom of the ice storage box 39 from the first embodiment. Specifically, the ice storage box 39 forms an inclined surface 39a from a substantially intermediate position in the front-rear direction (left-right direction in FIG. 8) of the refrigerator 1 to the bottom portion on the rear side. The height of the inclined surface 39a gradually increases in the vertical direction from the front side (left side in FIG. 8) to the back surface side (right side in FIG. 8) of the refrigerator. The inclined surface 39a may be provided over the entire area of the bottom of the ice storage box 39 in the front-rear direction.

第４の実施形態は、貯氷箱３９が、少なくとも奥側の底部に、奥側から手前側に向けて上下方向の高さが低くなる傾斜面３９ａが設けられている。このため、製氷皿４１から傾斜板４９に沿って貯氷箱３９に落下する氷が、傾斜面３９ａによって冷蔵庫前面側に移動する。これにより、貯氷箱３９に落下する氷が貯氷箱３９の奥側に溜まることを抑制でき、氷の取り出しが容易となって利便性が向上する。 In the fourth embodiment, the ice storage box 39 is provided with an inclined surface 39a whose height in the vertical direction decreases from the back side to the front side at least at the bottom of the back side. Therefore, the ice that falls from the ice tray 41 to the ice storage box 39 along the inclined plate 49 moves to the front side of the refrigerator by the inclined surface 39a. As a result, it is possible to prevent the ice that falls into the ice storage box 39 from accumulating in the back side of the ice storage box 39, making it easier to take out the ice and improving convenience.

［第５の実施形態］
図９は、第５の実施形態を示す、図３に対応する断面図である。第５の実施形態は、傾斜板４９と、傾斜板４９の下方の下冷凍室対応部３１ａとの間の空間に、電気配線の束線を結束した状態で収納する束線収納部としての束線収納箱５９を配置している。束線収納箱５９は、例えば冷蔵庫本体３の後壁３ａに取り付ける。電気配線としては、例えば駆動機構４３、冷気ファン３５や図示しない除霜用のヒータに接続されるものがある。 [Fifth Embodiment]
FIG. 9 is a cross-sectional view corresponding to FIG. 3, showing a fifth embodiment. A fifth embodiment is a bundle as a bundled wire storage unit that stores the bundled wires of electrical wiring in a space between the inclined plate 49 and the lower freezing chamber corresponding portion 31a below the inclined plate 49. A wire storage box 59 is arranged. The bundle wire storage box 59 is attached to, for example, the rear wall 3a of the refrigerator body 3. The electrical wiring includes, for example, a drive mechanism 43, a cold air fan 35, and a heater for defrosting (not shown).

第５の実施形態は、製氷皿４１の下方に電気配線の束線を結束した状態で収納する束線収納箱５９を配置している。これにより、製氷皿４１の下方の空間を有効利用できる。 In the fifth embodiment, a bundled wire storage box 59 for storing the bundled wires of electrical wiring in a bundled state is arranged below the ice tray 41. As a result, the space below the ice tray 41 can be effectively used.

［第６の実施形態］
図１０は、第６の実施形態を示す、図３に対応する断面図である。第６の実施形態は、貯氷箱３９の上方の製氷室内壁となる上部横隔壁４７の下面に、氷検知器としての氷検知レバー５３を、取付具５５を介して取り付けてある。氷検知レバー５３は、貯氷箱３９に貯蔵された氷によって先端側が押し上げられて、氷が満杯となったことを検知する。氷が貯蔵されていない場合には、氷検知レバー５３の先端が貯氷箱３９の底部付近まで垂れ下がり、氷が貯蔵されていないことを検知する。 [Sixth Embodiment]
FIG. 10 is a cross-sectional view corresponding to FIG. 3, showing a sixth embodiment. In the sixth embodiment, the ice detection lever 53 as an ice detector is attached to the lower surface of the upper horizontal partition wall 47, which is the wall of the ice making chamber above the ice storage box 39, via the fixture 55. The ice detection lever 53 detects that the tip side is pushed up by the ice stored in the ice storage box 39 and the ice is full. When the ice is not stored, the tip of the ice detection lever 53 hangs down to the vicinity of the bottom of the ice storage box 39, and detects that the ice is not stored.

第６の実施形態は、貯氷箱３９内の氷を検知する氷検知レバー５３が、貯氷箱３９の上方の上部横隔壁４７に取り付けられている。このため、氷検知レバー５３を製氷皿４１に取り付けることなく、貯氷箱３９に貯蔵された氷を検知することができ、製氷機３７の構造を簡素化できる。氷検知レバー５３は、先端が上方に押し上げられた状態が維持される構成とすることで、他の貯蔵物を製氷室９に貯蔵するときに、氷検知レバー５３が邪魔になることを抑制できる。 In the sixth embodiment, the ice detection lever 53 for detecting the ice in the ice storage box 39 is attached to the upper horizontal partition wall 47 above the ice storage box 39. Therefore, the ice stored in the ice storage box 39 can be detected without attaching the ice detection lever 53 to the ice tray 41, and the structure of the ice maker 37 can be simplified. The ice detection lever 53 is configured to maintain the state in which the tip is pushed upward, so that it is possible to prevent the ice detection lever 53 from becoming an obstacle when storing other stored items in the ice making chamber 9. ..
