ここでは、製氷装置２が冷蔵庫の庫内に配置されている場合を例にとって説明する。
製氷装置２は、上下に配置された２つの製氷皿１０Ａ，１０Ｂを備える。製氷皿１０Ａ，１０Ｂは、弾性を有する樹脂材料から形成される。製氷皿１０Ａ，１０Ｂは、仕切り壁１２で隔てられた複数の製氷領域１１を有する。製氷領域１１に貯留された飲料水等の液体を凍結させることにより、製氷領域１１の内面形状に対応した外形の複数の氷を作ることができる。 Here, a case where the ice making device 2 is arranged in the refrigerator is described as an example.
The ice making device 2 includes two ice making plates 10A and 10B arranged one above the other. The ice trays 10A and 10B are formed of an elastic resin material. The ice trays 10A and 10B have a plurality of ice making regions 11 separated by a partition wall 12. By freezing a liquid such as drinking water stored in the ice making region 11, a plurality of ice having an outer shape corresponding to the inner surface shape of the ice making region 11 can be produced.

本実施形態では、２つの製氷皿１０Ａ，１０Ｂを備えるが、これに限られるものではなく、上下に配置された３つ以上の製氷皿を備える場合もあり得る。また、本実施形態では、製氷皿１０Ａ，１０Ｂが、上下方向でほぼ完全に重なった位置に配置されているが、これに限られるものではない。複数の製氷皿が、平面視において、横方向に少しずれて配置される場合もあり得る。平面視における占有面積の増加を抑制する観点から、上下に配置された製氷皿の７０％以上が重なり合うのが好ましく、上下に配置された製氷皿の８０％以上が重なり合うのがより好ましい。 In the present embodiment, two ice trays 10A and 10B are provided, but the present invention is not limited to this, and three or more ice trays arranged one above the other may be provided. Further, in the present embodiment, the ice trays 10A and 10B are arranged at positions where they almost completely overlap in the vertical direction, but the present invention is not limited to this. A plurality of ice trays may be arranged with a slight lateral deviation in a plan view. From the viewpoint of suppressing an increase in the occupied area in a plan view, it is preferable that 70% or more of the ice trays arranged above and below overlap, and more preferably 80% or more of the ice trays arranged above and below overlap.

図４に示すように、上側に位置する製氷皿１０Ａの上方には、製氷皿１０Ａに液体を供給する液体供給口６０が配置されている。この場合、例えば、冷蔵庫内に配置された容器内に蓄えられた液体を、液体供給口６０から製氷皿１０Ａへ供給することもできるし、液体供給口６０が直接、水道管等と連結されている場合もあり得る。
液体供給口６０から上側の製氷皿１０に供給された液体の製氷皿１０Ａ，１０Ｂ内の流れについては、図６、図７を参照しながら、追って詳細に説明するが、概要は下記のようになる。 As shown in FIG. 4, a liquid supply port 60 for supplying a liquid to the ice tray 10A is arranged above the ice tray 10A located on the upper side. In this case, for example, the liquid stored in the container arranged in the refrigerator can be supplied from the liquid supply port 60 to the ice tray 10A, or the liquid supply port 60 is directly connected to the water pipe or the like. It is possible that there is.
The flow of the liquid supplied from the liquid supply port 60 to the upper ice tray 10 in the ice trays 10A and 10B will be described in detail later with reference to FIGS. 6 and 7, but the outline is as follows. Become.

液体供給口６０から上側の製氷皿１０Ａの１つの製氷領域１１に供給された液体は、製氷領域１１に液体を蓄えながら、スリット１３を介して、順に隣接した製氷領域１１へ流れる。更に、液体は、上側の製氷皿１０Ａの１つの製氷領域１１に設けられた穴１４から、下側の製氷皿１０Ｂへ流下する。そして、下側の製氷皿１０Ｂでも、製氷領域１１に液体を蓄えながら、スリット１３を介して、順に隣接した製氷領域１１へ流れる。これにより、製氷皿１０Ａ，１０Ｂの各製氷領域１１に液体が蓄えられる。 The liquid supplied from the liquid supply port 60 to one ice making region 11 of the upper ice tray 10A flows to the adjacent ice making regions 11 in order through the slit 13 while storing the liquid in the ice making region 11. Further, the liquid flows down from the hole 14 provided in one ice making region 11 of the upper ice tray 10A to the lower ice tray 10B. Then, even in the lower ice tray 10B, the liquid is stored in the ice making region 11 and flows to the adjacent ice making regions 11 in order through the slit 13. As a result, the liquid is stored in each ice making region 11 of the ice making trays 10A and 10B.

上側に位置する製氷皿１０Ａの上方には、製氷皿１０Ａの上側の空間に気体を供給するファン４０を備える。本実施形態では、冷蔵庫の蒸発器を通過して冷却された気体が、ファン４０により、製氷装置２内に取り込まれ、製氷皿１０Ａの上側の空間に供給される。製氷装置２は、製氷皿１０Ａ，１０Ｂの側方に配置され、上側の製氷皿１０Ａの上側の空間及び下側の製氷皿１０Ｂの上側の空間の間を繋ぐダクト５０を備える。
このような構成により、冷蔵庫の蒸発器を通過した冷気が、ファン４０により供給され、上側の製氷皿１０Ａの上側の空間及び下側の製氷皿１０Ｂの上側の空間を流れる。これによって、製氷皿１０Ａ，１０Ｂに貯留された液体が凍結し、氷が形成される。この気体の流れについては、図５を参照しながら、追って詳細に述べる。 Above the ice tray 10A located on the upper side, a fan 40 for supplying gas to the space above the ice tray 10A is provided. In the present embodiment, the gas cooled through the evaporator of the refrigerator is taken into the ice making device 2 by the fan 40 and supplied to the space above the ice making tray 10A. The ice making device 2 is arranged on the side of the ice trays 10A and 10B, and includes a duct 50 connecting the space above the ice tray 10A on the upper side and the space above the ice tray 10B on the lower side.
With such a configuration, the cold air that has passed through the evaporator of the refrigerator is supplied by the fan 40 and flows through the space above the upper ice tray 10A and the space above the lower ice tray 10B. As a result, the liquids stored in the ice trays 10A and 10B are frozen to form ice. The flow of this gas will be described in detail later with reference to FIG.

製氷装置２は、更に、２つの製氷皿１０Ａ，１０Ｂを回転させるための回転機構２０及び軸受け部２４を備える。製氷皿１０Ａ，１０Ｂの両端には、駆動軸部１５及び非駆動軸部１６を有する。製氷皿１０Ａ，１０Ｂの駆動軸部１５は、それぞれ回転機構２０の上下の保持部２２Ａ，２２Ｂに取り付けられている。保持部２２Ａ，２２Ｂは、回転機構２０に備えられた電動モータにより回転する。製氷皿１０Ａ，１０Ｂの非駆動軸部１６は、それぞれ軸受け部２４の上下の穴部に挿入されている。 The ice making device 2 further includes a rotating mechanism 20 and a bearing portion 24 for rotating the two ice making plates 10A and 10B. A drive shaft portion 15 and a non-drive shaft portion 16 are provided at both ends of the ice trays 10A and 10B. The drive shaft portions 15 of the ice trays 10A and 10B are attached to the upper and lower holding portions 22A and 22B of the rotating mechanism 20, respectively. The holding portions 22A and 22B are rotated by an electric motor provided in the rotating mechanism 20. The non-driving shaft portions 16 of the ice trays 10A and 10B are inserted into the upper and lower holes of the bearing portion 24, respectively.

このような構成により、製氷皿１０Ａ，１０Ｂは、回転機構２０の駆動力により、それぞれ回転軸Ｘａ及びＸｂを中心に回転する。製氷皿１０Ａ，１０Ｂの回転位置としては、製氷皿１０Ａ，１０Ｂの上面１８が上側を向き、液体を貯留可能な製氷位置がある。製氷皿１０Ａ，１０Ｂの製氷領域１１における液体の貯留効率を考慮すると、製氷皿１０Ａ，１０Ｂの上面１８が水平となった位置が好ましいが、上面１８がやや傾斜した位置の場合もあり得る。
更に、製氷皿１０Ａ，１０Ｂの回転位置として、製氷領域１１内で形成された氷を離脱させて落下させる脱氷位置がある。脱氷位置では、氷を落下させるため、上面１８が下向きになっている必要があるが、水平にまで達する必要はなく、下向きに傾斜した位置でもよい。 With such a configuration, the ice trays 10A and 10B rotate about the rotation axes Xa and Xb, respectively, by the driving force of the rotation mechanism 20. As the rotation position of the ice trays 10A and 10B, there is an ice making position where the upper surface 18 of the ice trays 10A and 10B faces upward and the liquid can be stored. Considering the liquid storage efficiency in the ice making region 11 of the ice trays 10A and 10B, it is preferable that the upper surface 18 of the ice trays 10A and 10B is horizontal, but the upper surface 18 may be slightly inclined.
Further, as the rotation position of the ice trays 10A and 10B, there is a deicing position where the ice formed in the ice making region 11 is separated and dropped. At the deicing position, the upper surface 18 needs to be downward in order to drop the ice, but it is not necessary to reach the horizontal position, and the ice may be inclined downward.

回転機構２０の駆動力により、上面１８が上側を向いた製氷位置から、製氷皿１０Ａ，１０Ｂを回転させていくと、上面１８が下側を向くようになり、製氷皿１０Ａ，１０Ｂの非駆動軸部１６側の端部に設けられた凸部１７が、軸受け部２４に設けられたストッパと当接する。当接後も回転機構２０が駆動を続けると、製氷皿１０Ａ，１０Ｂの非駆動軸部１６側は、ほぼ回転が停止するが、駆動軸部１５側が回転を継続することになる。これにより、弾性材料からなる製氷皿１０Ａ，１０Ｂに捻じれが生じて、各製氷領域１１から氷が離脱し、重力で落下する。このように、製氷皿１０Ａ，１０Ｂの上面１８が下側を向くとともに、捻じれた状態となって停止した位置が脱氷位置となる。 When the ice trays 10A and 10B are rotated from the ice making position where the upper surface 18 faces upward by the driving force of the rotation mechanism 20, the upper surface 18 faces downward and the ice trays 10A and 10B are not driven. The convex portion 17 provided at the end on the shaft portion 16 side comes into contact with the stopper provided on the bearing portion 24. If the rotation mechanism 20 continues to drive even after the contact, the rotation of the non-drive shaft portions 16 side of the ice trays 10A and 10B is almost stopped, but the drive shaft portion 15 side continues to rotate. As a result, the ice trays 10A and 10B made of the elastic material are twisted, the ice is separated from each ice making region 11, and the ice trays 10A and 10B are dropped by gravity. In this way, the upper surface 18 of the ice trays 10A and 10B faces downward, and the position where the ice trays 10A and 10B stop in a twisted state is the deicing position.

本実施形態では、回転機構２０が１つの電動モータを有し、歯車の伝達機構により、２つの製氷皿１０Ａ，１０Ｂが同時に回転する。ただし、これに限られるものではなく、２つの製氷皿１０Ａ，１０Ｂが、個別に回転するようにすることもできる。製氷皿１０Ａ，１０Ｂを回転させて、捻じって脱氷させる機構については、既知の任意の脱氷機構を用いることができる。
製氷皿１０Ａ，１０Ｂから落下した氷の進み方については、図５を参照しながら、追って詳細に述べる。 In the present embodiment, the rotation mechanism 20 has one electric motor, and the two ice trays 10A and 10B rotate at the same time by the transmission mechanism of the gear. However, the present invention is not limited to this, and the two ice trays 10A and 10B can be rotated individually. Any known deicing mechanism can be used as the mechanism for rotating, twisting, and deicing the ice trays 10A and 10B.
The way the ice that has fallen from the ice trays 10A and 10B advances will be described in detail later with reference to FIG.

（製氷皿１０Ａ，１０Ｂ内の液体に流れ）
図６，図７に示すように、製氷皿１０Ａ，１０Ｂには、それぞれ、仕切り壁１２で隔てられた２列×５個の計１０個の製氷領域１１が設けられている。ただし、製氷領域１１の配置は、これに限られるものではない。仕切り壁１２には、スリット１３が設けられている。スリット１３は、製氷領域１１の底面から所定の高さｈの位置から、仕切り壁１２の上端まで設けられている。よって、製氷領域１１内での液体の液面が所定の高さｈを越えると、隣の製氷領域１１へ流入する。これにより、製氷皿１０Ａ，１０Ｂの１つの製氷領域１１に液体を供給すれば、各製氷領域１１において、高さｈまで液体を蓄えることができる。 (Flows into the liquid in the ice trays 10A and 10B)
As shown in FIGS. 6 and 7, each of the ice trays 10A and 10B is provided with a total of 10 ice making regions 11 of 2 rows × 5 separated by a partition wall 12. However, the arrangement of the ice making region 11 is not limited to this. The partition wall 12 is provided with a slit 13. The slit 13 is provided from a position at a predetermined height h from the bottom surface of the ice making region 11 to the upper end of the partition wall 12. Therefore, when the liquid level in the ice making region 11 exceeds a predetermined height h, the liquid flows into the adjacent ice making region 11. As a result, if the liquid is supplied to one ice making region 11 of the ice trays 10A and 10B, the liquid can be stored up to the height h in each ice making region 11.

＜上側の製氷皿１０Ａ＞
液体供給口６０は、上側の製氷皿１０Ａの非駆動軸部１６側の端部に位置する２つ製氷領域１１のうちの１つの製氷領域１１の上方に設置されている。非駆動軸部１６側の端部に位置する隣の列の２つ製氷領域１１の間、及び駆動軸部１５側の端部に位置する隣の列の２つ製氷領域１１の間に、スリット１３が設けられている。また、列方向で隣接する製氷領域１１の間に、スリット１３が設けられている。更に、駆動軸部１５側の端部に位置する２つ製氷領域１１のうちの１つの製氷領域１１の下部に、液体が落下する穴１４が設けられている。 <Upper ice tray 10A>
The liquid supply port 60 is installed above the ice making region 11 of one of the two ice making regions 11 located at the end of the upper ice tray 10A on the non-driving shaft portion 16 side. Slits between the two ice-making regions 11 in the adjacent row located at the end on the non-drive shaft 16 side and between the two ice-making regions 11 in the adjacent row located at the end on the drive shaft 15 side. 13 is provided. Further, a slit 13 is provided between the ice making regions 11 adjacent to each other in the row direction. Further, a hole 14 into which the liquid falls is provided in the lower part of one of the two ice making regions 11 located at the end on the drive shaft portion 15 side.

以上のようなスリット１３及び穴１４の配置により、液体供給口６０から、非駆動軸部１６側の端部の１つ製氷領域１１に供給された液体は、図６の点線の矢印に示すように、非駆動軸部１６側から駆動軸部１５側に、列ごとに二手に分かれて流れ、非駆動軸部１６側の端部に位置する１つの製氷領域１１の穴１４から下方へ流れ落ちる。これにより、穴１４を有する製氷領域１１を除く、上側の製氷皿１０Ａの全ての製氷領域１１に、液面高さｈの液体が貯留される。両端部の製氷領域１１にだけ、隣の列の製氷領域１１との間にスリットを設けることにより、列ごとに二手に分かれたスムーズな液体の流れを実現できる。 By arranging the slits 13 and the holes 14 as described above, the liquid supplied from the liquid supply port 60 to one ice making region 11 at the end on the non-drive shaft portion 16 side is shown by the dotted arrow in FIG. In addition, the liquid flows from the non-driving shaft portion 16 side to the driving shaft portion 15 side in two separate rows, and flows downward from the hole 14 of one ice making region 11 located at the end of the non-driving shaft portion 16 side. As a result, the liquid having a liquid level h is stored in all the ice making regions 11 of the upper ice tray 10A except for the ice making region 11 having the holes 14. By providing slits only in the ice making regions 11 at both ends and between the ice making regions 11 in the adjacent row, it is possible to realize a smooth liquid flow divided into two hands for each row.

＜下側の製氷皿１０Ｂ＞
下側の製氷皿１０Ｂでも、非駆動軸部１６側の端部に位置する隣の列の２つ製氷領域１１の間、及び駆動軸部１５側の端部に位置する隣の列の２つ製氷領域１１の間に、スリット１３が設けられている。また、列方向で隣接する製氷領域１１の間に、スリット１３が設けられている。下側の製氷皿１０Ｂには、穴１４を有する製氷領域１１はない。 <Lower ice tray 10B>
Even in the lower ice tray 10B, between the two ice making regions 11 in the adjacent row located at the end on the non-driving shaft 16 side and in the adjacent row located at the end on the driving shaft 15 side. A slit 13 is provided between the ice making regions 11. Further, a slit 13 is provided between the ice making regions 11 adjacent to each other in the row direction. The lower ice tray 10B does not have an ice region 11 with holes 14.

以上のようなスリット１３の配置により、上側の製氷皿１０Ａから、駆動軸部１５側の端部の１つ製氷領域１１に流れ落ちた液体は、図７の点線の矢印に示すように、駆動軸部１５側から非駆動軸部１６側に列ごとに二手に分かれて流れる。これにより、下側の製氷皿１０Ｂの全ての製氷領域１１に、液面高さｈの液体が貯留される。下側の製氷皿１０Ｂにおいても、両端部の製氷領域１１にだけ、隣の列の製氷領域１１との間にスリットを設けることにより、列ごとに二手に分かれたスムーズな液体の流れを実現できる。 Due to the arrangement of the slits 13 as described above, the liquid that has flowed down from the upper ice tray 10A to one of the ice making regions 11 at the end on the drive shaft portion 15 side is the drive shaft as shown by the dotted arrow in FIG. The flow is divided into two for each row from the portion 15 side to the non-drive shaft portion 16 side. As a result, the liquid having a liquid level h is stored in all the ice making regions 11 of the lower ice making tray 10B. Also in the lower ice tray 10B, by providing slits only in the ice making regions 11 at both ends and between the ice making regions 11 in the adjacent row, it is possible to realize a smooth liquid flow divided into two hands for each row. ..

ただし、上記の製氷皿１０Ａ、１０Ｂにおけるスリット１３の配置は、あくまで一例であって、製氷領域１１の配置に応じて、その他の任意のスリット１３の配置を採用できる。本実施形態では、上側の製氷皿１０Ａに１つの穴１４が設けられているが、これに限られるものではなく、製氷皿１０Ａの複数の製氷領域１１の下部に、液体が落下する穴１４を設けることもできる。 However, the arrangement of the slits 13 in the ice trays 10A and 10B described above is merely an example, and any other arrangement of the slits 13 can be adopted depending on the arrangement of the ice making region 11. In the present embodiment, one hole 14 is provided in the upper ice tray 10A, but the present invention is not limited to this, and a hole 14 into which the liquid falls is provided in the lower portion of the plurality of ice making regions 11 of the ice tray 10A. It can also be provided.

また、上下に３つ以上の製氷皿１０が備えられた場合でも、最も上側に位置する製氷皿１０の１つの製氷領域１１に液体を供給するように、液体供給口６０を配置すればよい。また、１つの製氷領域１１に、液体供給口６０から液体を供給する場合に限られず、複数の製氷領域１１に、液体供給口６０から液体を供給することもできる。その場合には、複数の液体供給口６０の位置に応じて、各液体供給口６０からの液体の流れが干渉しないように、スリット１３を配置するのが好ましい。 Further, even when three or more ice trays 10 are provided on the upper and lower sides, the liquid supply port 60 may be arranged so as to supply the liquid to one ice making region 11 of the ice tray 10 located on the uppermost side. Further, the liquid is not limited to the case where the liquid is supplied to one ice making region 11 from the liquid supply port 60, and the liquid can be supplied to a plurality of ice making regions 11 from the liquid supply port 60. In that case, it is preferable to arrange the slits 13 according to the positions of the plurality of liquid supply ports 60 so that the flow of liquid from each liquid supply port 60 does not interfere with each other.

以上のように、製氷皿１０Ａ，１０Ｂの仕切り壁１２に設けられたスリット１３により、少なくとも１つの製氷領域１１に液体を供給すれば、製氷領域１１に液体を貯留するとともに、他の製氷領域１１にも液体を供給することができる。 As described above, if the liquid is supplied to at least one ice making region 11 by the slit 13 provided in the partition wall 12 of the ice trays 10A and 10B, the liquid is stored in the ice making region 11 and the other ice making region 11 is stored. Can also supply liquid.

更に、最も上側に位置する製氷皿１０Ａの少なくとも１つの製氷領域１１に液体を供給する液体供給口６０が備えられており、液体供給口６０が配置された製氷領域１１を除く、上側に位置する製氷皿１０Ａの少なくとも１つの製氷領域１１の下部に、液体が落下する穴１４を有するので、特別な動力を使わずに、上下の製氷皿１０Ａ，１０Ｂの全ての製氷領域１１に効率的に液体を供給することができる。 Further, a liquid supply port 60 for supplying liquid to at least one ice making region 11 of the ice tray 10A located on the uppermost side is provided, and the liquid supply port 60 is located on the upper side except for the ice making region 11 in which the liquid supply port 60 is arranged. Since the lower part of at least one ice making region 11 of the ice tray 10A has a hole 14 into which the liquid falls, the liquid can be efficiently applied to all the ice making regions 11 of the upper and lower ice trays 10A and 10B without using special power. Can be supplied.

（気体の流れ）
製氷装置２における気体の流れを、図５を参照しながら説明する。図５では、気体の流れを一点鎖線の矢印で模式的に示す。上側の製氷皿１０Ａの上側の空間の図面右側の端部は、壁部３４により閉鎖されている(図１、２参照）。よって、冷蔵庫の蒸発器を通過して冷却され、ファン４０により下方に吐出された気体は、ファン４０の下部や上側の製氷皿１０Ａの上側の空間を図面右側から左側へ流れる。下方に吐出された気体の流れにより、製氷皿１０Ａの各製氷領域１１に貯留された液体が冷却される。そして、ファン４０の下部や製氷皿１０Ａの上側の空間を流れた気体は、製氷皿１０Ａ，１０Ｂの側方に配置され、上側の製氷皿１０Ａの上側の空間及び下側の製氷皿１０Ｂの上側の空間の間を繋ぐダクト５０に流入する。ダクト５０は、気体が少ない圧損でスムーズに流れるように、湾曲面や傾斜面を有する流路が形成されている。 (Gas flow)
The flow of gas in the ice making apparatus 2 will be described with reference to FIG. In FIG. 5, the gas flow is schematically shown by a long-dotted arrow. The right end of the drawing of the upper space of the upper ice tray 10A is closed by the wall 34 (see FIGS. 1 and 2). Therefore, the gas that has passed through the evaporator of the refrigerator and is cooled and discharged downward by the fan 40 flows from the right side to the left side of the drawing in the space above the ice tray 10A below and above the fan 40. The liquid stored in each ice-making region 11 of the ice-making tray 10A is cooled by the flow of the gas discharged downward. The gas that has flowed through the lower part of the fan 40 and the space above the ice tray 10A is arranged on the side of the ice trays 10A and 10B, and is arranged on the side of the ice trays 10A and 10B. It flows into the duct 50 that connects the spaces of the space. The duct 50 is formed with a flow path having a curved surface or an inclined surface so that the gas can flow smoothly with a small pressure loss.

そして、気体は、ダクト５０内を上から下へ流れ、下側の製氷皿１０Ｂの上側の空間に流入する。そして、気体は、下側の製氷皿１０Ｂの上側の空間を、図面左側から右側へ流れる。この流れにより、製氷皿１０Ｂの各製氷領域１１に貯留された液体が冷却される。そして、製氷皿１０Ｂの上側の空間を流れた気体は、カバー３０に設けられた開口３２(図１，２参照）から、製氷装置２の外部へ流出する。製氷装置２の外部へ流出した気体は、冷蔵庫の内部を流れ、再び冷蔵庫の蒸発器を通過して冷却される。 Then, the gas flows in the duct 50 from top to bottom and flows into the space above the lower ice tray 10B. Then, the gas flows from the left side to the right side of the drawing in the space above the lower ice tray 10B. This flow cools the liquid stored in each ice making region 11 of the ice tray 10B. Then, the gas that has flowed through the space above the ice tray 10B flows out of the ice making device 2 through the openings 32 (see FIGS. 1 and 2) provided in the cover 30. The gas flowing out of the ice making device 2 flows inside the refrigerator, passes through the evaporator of the refrigerator again, and is cooled.

本実施形態では、上側の製氷皿１０Ａの上方にファン４０が配置されているが、これに限られるものではない。例えば、下側の製氷皿１０Ｂ側にファン４０を配置して、ダクト５０を介して、下側の製氷皿１０Ｂ側から上側の製氷皿１０Ｂ側に気体を流すこともできる。また、上下に３つ以上の製氷皿１０が配置されている場合には、そのうちの１つの製氷皿１０の位置に、ファン４０を配置することもできるし、高さの異なる複数の製氷皿１０の位置に、ファン４０を配置することもできる。 In the present embodiment, the fan 40 is arranged above the upper ice tray 10A, but the present invention is not limited to this. For example, a fan 40 may be arranged on the lower ice tray 10B side, and gas may flow from the lower ice tray 10B side to the upper ice tray 10B side via the duct 50. Further, when three or more ice trays 10 are arranged one above the other, the fan 40 can be arranged at the position of one of the ice trays 10, and a plurality of ice trays 10 having different heights can be arranged. The fan 40 can also be arranged at the position of.

以上のように、製氷装置２は、少なくとも１つの製氷皿１０Ａの上側の空間に気体を供給するファン４０と、製氷皿１０Ａ，１０Ｂの側方に配置され、上側の製氷皿１０Ａの上側の空間及び下側の製氷皿１０Ｂの上側の空間の間を繋ぐダクト５０とを備える。ファン４０は、気体供給部と称することもできる。これにより、ファン４０から少なくとも１つの製氷皿１０Ａに気体を供給すれば、製氷皿１０Ａ，１０Ｂの側方に配置されたダクト５０により、他の製氷皿１０Ｂへも気体を供給できる。これにより、少ない数のファン４０で、効率的に製氷皿１０Ａ，１０Ｂに貯留された液体を冷却することができる。 As described above, the ice making device 2 is arranged on the side of the fan 40 that supplies gas to the space above the at least one ice tray 10A and the ice trays 10A and 10B, and is arranged on the side of the ice trays 10A and 10B. And a duct 50 connecting between the space above the lower ice tray 10B. The fan 40 can also be referred to as a gas supply unit. As a result, if gas is supplied from the fan 40 to at least one ice tray 10A, the gas can be supplied to the other ice trays 10B by the ducts 50 arranged on the sides of the ice trays 10A and 10B. As a result, the liquid stored in the ice trays 10A and 10B can be efficiently cooled with a small number of fans 40.

＜変形例＞
上記の実施形態では、製氷装置２が気体を供給するファン４０を備えているが、これに限られるものではない。図９は、製氷装置２の変形例を説明するために模式的に示す冷蔵庫の側面断面図である。図９に示すように、製氷装置２の周辺に冷気の吐出口（例えば、開口１１２）があれば、ファン４０が無くとも、冷気を製氷装置２内に導入する吸入口４２があれば、上記と同様な機能を果たすことができる。 <Modification example>
In the above embodiment, the ice making device 2 includes a fan 40 for supplying gas, but the present invention is not limited to this. FIG. 9 is a side sectional view of a refrigerator schematically shown for explaining a modification of the ice making device 2. As shown in FIG. 9, if there is a cold air discharge port (for example, opening 112) around the ice making device 2, there is a suction port 42 that introduces cold air into the ice making device 2 even if there is no fan 40. Can perform the same function as.

図９では、冷蔵庫１００の蒸発器１２６を通過した冷気を冷凍室１１０内に送る開口１１２の近傍に、製氷装置２が配置されている。この場合、製氷皿１０Ａの上側空間の側方または上方に吸入口を設ければ、１つの製氷皿１０Ａの上側の空間に気体を取り込むことができる。図９では、製氷皿１０Ａの上側空間の側方に、気体供給部として機能する吸入口４２が設けられている。これにより、蒸発器１２６を通過した冷気を、直接、製氷皿１０Ａの上側の空間に気体を取り込むことができる。製氷皿１０Ａの上側空間の側方に吸入口４２を設ける場合、気体の流れを考えると、ダクト５０が設けられた側と反対側の位置に吸入口を設けるのが好ましい。 In FIG. 9, the ice making device 2 is arranged in the vicinity of the opening 112 that sends the cold air that has passed through the evaporator 126 of the refrigerator 100 into the freezing chamber 110. In this case, if a suction port is provided on the side or above the space above the ice tray 10A, gas can be taken into the space above the ice tray 10A. In FIG. 9, a suction port 42 that functions as a gas supply unit is provided on the side of the upper space of the ice tray 10A. As a result, the cold air that has passed through the evaporator 126 can be directly taken into the space above the ice tray 10A. When the suction port 42 is provided on the side of the upper space of the ice tray 10A, it is preferable to provide the suction port at a position opposite to the side where the duct 50 is provided, considering the gas flow.

ファン４０を備える場合及び吸入口４２を備える場合をまとめて表現すれば、「製氷装置２が、少なくとも１つの製氷皿１０Ａの上側の空間に気体を供給する気体供給部４０、４２と、製氷皿１０Ａ，１０Ｂの側方に配置され、上側の製氷皿１０Ａの上側の空間及び下側の製氷皿１０Ｂの上側の空間の間を繋ぐダクト５０とを備える」ということができる。 The case where the fan 40 is provided and the case where the suction port 42 is provided are collectively expressed as follows: "The ice making device 2 has gas supply units 40 and 42 for supplying gas to the space above at least one ice making dish 10A, and the ice making dish. It is provided on the side of 10A and 10B, and includes a duct 50 connecting the upper space of the upper ice tray 10A and the upper space of the lower ice tray 10B. "

（氷の落下）
回転機構２０により製氷皿１０Ａ，１０Ｂが脱氷位置まで回転して、製氷皿１０Ａ，１０Ｂから離脱、落下する氷のその後の進み方について、図５を参照しながら説明する。図５の点線の矢印で模式的に示すように、下側の製氷皿１０Ｂから外れた氷は、重力により、製氷装置２の下方に設置された収納容器７０にそのまま落下する。一方、上側の製氷皿１０Ａから外れた氷は、下方に下側の製氷皿１０Ｂが存在するので、そのまま収納容器７０にアクセスすることができない。 (Falling ice)
The subsequent way of advancing the ice that the ice trays 10A and 10B rotate to the deicing position by the rotation mechanism 20 and separate from and fall from the ice trays 10A and 10B will be described with reference to FIG. As schematically shown by the dotted arrow in FIG. 5, the ice that has come off from the lower ice tray 10B falls as it is into the storage container 70 installed below the ice making device 2 due to gravity. On the other hand, the ice that has come off the upper ice tray 10A cannot access the storage container 70 as it is because the lower ice tray 10B exists below.

本実施形態に係る製氷装置２では、下側に位置する製氷皿１０Ｂの上部に、上側に位置する製氷皿１０Ａから落下した氷が、下側に位置する製氷皿１０Ｂの側方を落下するようにガイドするカバー３０が備えられている。更に詳細に述べれば、本実施形態に係るカバー３０は、湾曲面を有している。これにより、上側の製氷皿１０Ａから落下した氷は、湾曲面に沿って移動し、製氷装置２の側方から、製氷装置２の下方に設置された収納容器７０に落下する。これにより、氷や機器の損傷を抑制しながら、上側の製氷皿１０Ａから落下した氷を、スムーズに収納容器７０に収納することができる。 In the ice making device 2 according to the present embodiment, the ice that has fallen from the ice making dish 10A located on the upper side falls on the side of the ice making dish 10B located on the lower side on the upper part of the ice making dish 10B located on the lower side. A cover 30 is provided to guide the ice. More specifically, the cover 30 according to the present embodiment has a curved surface. As a result, the ice that has fallen from the upper ice tray 10A moves along the curved surface and falls from the side of the ice making device 2 into the storage container 70 installed below the ice making device 2. As a result, the ice that has fallen from the upper ice tray 10A can be smoothly stored in the storage container 70 while suppressing damage to ice and equipment.

ただし、カバー３０は、必ず湾曲面を有する必要はなく、落下してきた氷の進行方向を斜め下方向に変更して、下側に位置する製氷皿１０Ｂの側方を落下するようにできれば、その他の任意の形状を有することができる。例えば、傾斜面した平面を有するカバー３０を用いて、落下してきた氷の進行方向を斜め下方向に変更することもできる。更に、カバー３０が、湾曲曲面及び傾斜面の両方を備えた形状を有する場合もあり得る。

(冷蔵庫）
図８は、製氷装置２を備えた冷蔵庫１００の一例を模式的に示す側面断面図である。次に、図８を参照しながら、上記の実施形態に係る製氷装置２を備えた冷蔵庫１００の一例の説明を行う。図８では、説明のため、冷蔵庫に比べて、製氷装置２や液体供給装置１３０を大きく描いている。 (refrigerator)
FIG. 8 is a side sectional view schematically showing an example of a refrigerator 100 provided with an ice making device 2. Next, an example of the refrigerator 100 provided with the ice making device 2 according to the above embodiment will be described with reference to FIG. In FIG. 8, for the sake of explanation, the ice making device 2 and the liquid supply device 130 are drawn larger than the refrigerator.

製氷装置２が、冷蔵庫１００の冷凍室１１０の背面側に配置され、その下方に、氷の収納容器７０が配置されている。冷蔵庫１００には、製氷装置２の製氷皿１０Ａ，１０Ｂに液体を供給する液体供給装置１３０を備える。液体供給装置１３０では、タンク１３２に蓄えられた液体を、ポンプ１３４の吐出力で配管１３６側へ供給する。そして、配管１３６内を流下した液体が、液体供給口６０から製氷装置２の上側の製氷皿１０Ａに供給される。 The ice making device 2 is arranged on the back side of the freezing chamber 110 of the refrigerator 100, and the ice storage container 70 is arranged below the ice making device 2. The refrigerator 100 includes a liquid supply device 130 that supplies liquid to the ice trays 10A and 10B of the ice making device 2. In the liquid supply device 130, the liquid stored in the tank 132 is supplied to the pipe 136 side by the discharge force of the pump 134. Then, the liquid flowing down the pipe 136 is supplied from the liquid supply port 60 to the ice tray 10A on the upper side of the ice making device 2.

冷蔵庫１００は、庫内に冷気を供給するため、主に圧縮器１２２，凝縮器１２４及び蒸発器１２６により、冷却サイクルを形成する冷却機構１２０を備える。冷蔵庫１００の庫内を循環する気体は、蒸発器１２６を通過するときに冷却される。そして、一点鎖線の矢印に示すように、蒸発器１２６における熱交換で冷却された気体が、冷蔵庫ファン１２８により、開口１１２を介して、冷凍室１１０内に吹き込まれる。冷凍室１１０内に吹き込まれた気体の一部は、製氷装置２のファン４０により、製氷装置２内に取り込まれ、上側の製氷皿１０Ａの上側の空間に供給される。製氷装置２内に取り込まれた気体は、上側の製氷皿１０Ａの上側の空間から、ダクトを介して、下側の製氷皿１０Ｂの上側の空間に流れ、カバーに設けられた開口から、製氷装置２の外部へ流れ出る。流れ出た気体は、開口１１４を介して、冷却機構１２０側へ流れ、再び蒸発器１２６を通過するときに冷却される。このような気体の循環が繰り返されて、製氷装置２内に冷却された気体が継続的に供給され、製氷皿１０Ａ，１０Ｂ内の液体が凍結して、氷が作られる。 The refrigerator 100 includes a cooling mechanism 120 that forms a cooling cycle mainly by a compressor 122, a condenser 124, and an evaporator 126 in order to supply cold air into the refrigerator. The gas circulating in the refrigerator 100 is cooled as it passes through the evaporator 126. Then, as shown by the arrow of the alternate long and short dash line, the gas cooled by heat exchange in the evaporator 126 is blown into the freezing chamber 110 by the refrigerator fan 128 through the opening 112. A part of the gas blown into the freezer chamber 110 is taken into the ice making device 2 by the fan 40 of the ice making device 2 and supplied to the space above the upper ice making dish 10A. The gas taken into the ice making device 2 flows from the upper space of the upper ice making dish 10A to the upper space of the lower ice making dish 10B through a duct, and from the opening provided in the cover, the ice making device. It flows out of 2. The gas that has flowed out flows to the cooling mechanism 120 side through the opening 114, and is cooled when it passes through the evaporator 126 again. Such gas circulation is repeated, the cooled gas is continuously supplied into the ice making apparatus 2, and the liquids in the ice trays 10A and 10B are frozen to make ice.

以上のように、製氷皿１０Ａ，１０Ｂが上下に配置された製氷装置２を備えた冷蔵庫１００では、平面視において、製氷皿を横に並べる場合に比べて占有面積を小さくすることができる。これにより、収納効率の低下を抑制しながら、より多くの氷を供給可能な冷蔵庫１００を提供できる。
図９に示すように、製氷装置２が、ファン４０の代わりに気体吸入口４２を備える場合もあり得る。その場合には、開口１１２を介して冷凍室１１０内に吹き込まれた冷気を、気体吸入口４２から、製氷装置２内に直接取り込んで、上側の製氷皿１０Ａの上側の空間に供給することができる。 As described above, in the refrigerator 100 provided with the ice making devices 2 in which the ice making plates 10A and 10B are arranged vertically, the occupied area can be reduced as compared with the case where the ice making plates are arranged side by side in a plan view. This makes it possible to provide the refrigerator 100 capable of supplying more ice while suppressing a decrease in storage efficiency.
As shown in FIG. 9, the ice making device 2 may include a gas suction port 42 instead of the fan 40. In that case, the cold air blown into the freezing chamber 110 through the opening 112 can be directly taken into the ice making device 2 from the gas suction port 42 and supplied to the space above the upper ice making dish 10A. it can.

＜変形例＞
上記の実施形態に係る冷蔵庫１００では、製氷装置２が冷凍室１１０の内部に配置されているが、これに限られるものではない。複数の製氷皿１０Ａ，１０Ｂが上下に配置されているので、例えば、製氷装置２を冷蔵庫１００の扉の中にも比較的容易に配置できる。その場合、扉の開閉により、製氷皿内の水が飛び散る虞がある。 <Modification example>
In the refrigerator 100 according to the above embodiment, the ice making device 2 is arranged inside the freezing chamber 110, but the present invention is not limited to this. Since the plurality of ice trays 10A and 10B are arranged vertically, for example, the ice making device 2 can be arranged relatively easily in the door of the refrigerator 100. In that case, opening and closing the door may cause water in the ice tray to scatter.

これに対処するため、図４，図５に示すように、製氷領域１１の列に沿った（つまり、長手方向に沿った）製氷皿１０Ａ，１０Ｂの両側面の突起に当接するように、ガイドカバー１９が取り付けられている。ガイドカバー１９は、製氷皿１０Ａ，１０Ｂの上面１８より上方に延びている。これにより、扉の開閉により飛び跳ねた水は、ガイドカバー１９に当たり、ガイドカバー１９の内面を伝わって、製氷皿１０Ａ，１０Ｂの製氷領域１１に戻るようになっている。このガイドカバー１９により、扉を開け閉めしても、製氷皿１０Ａ，１０Ｂの中の液体が外にこぼれ落ちるのを防ぐことができる。 To deal with this, as shown in FIGS. 4 and 5, a guide is provided so as to abut on the protrusions on both sides of the ice trays 10A and 10B along the row of the ice making region 11 (that is, along the longitudinal direction). The cover 19 is attached. The guide cover 19 extends upward from the upper surface 18 of the ice trays 10A and 10B. As a result, the water splashed by opening and closing the door hits the guide cover 19, travels along the inner surface of the guide cover 19, and returns to the ice making regions 11 of the ice trays 10A and 10B. The guide cover 19 can prevent the liquid in the ice trays 10A and 10B from spilling out even if the door is opened and closed.

製氷皿１０Ａ，１０Ｂの突起やガイドカバー１９は、柔軟性のある樹脂材料から形成されているので、脱氷のために製氷皿１０Ａ，１０Ｂを捻ったときの応力や、冷蔵庫の扉を強く開け閉めしたときの振動にも十分に対応できるようになっている。
以上のように、上記の実施形態に係る製氷装置２を扉の内部に備えた冷蔵庫２において、製氷皿１０Ａ，１０Ｂの長手方向に沿った両側面に、製氷皿１０Ａ，１０Ｂの上面１８より上方に延びたガイドカバー１９を備えることにより、扉の開閉による製氷皿１０Ａ，１０Ｂの中の液体の飛び跳ねを効果的に防ぐことができる。 Since the protrusions and guide covers 19 of the ice trays 10A and 10B are made of a flexible resin material, the stress when the ice trays 10A and 10B are twisted for deicing and the refrigerator door are strongly opened. It is designed to handle vibrations when it is closed.
