図３に示すように、第１製氷皿１１と第２製氷皿１２は氷室の形状が異なり、大きさも第１製氷皿の氷室１１ａで生成される氷１個の体積は１ｍｌで、第２製氷皿の氷室１２ａで生成される氷１個の体積は８ｍｌであるというように差を持たせている。たとえば、具体的には大きい氷は一般的なキューブ状のほかにロック状や半球状、小さい氷は一般的なキューブ状のほかにフレーク状やクラッシュ状などと特徴を持たせている。 As shown in FIG. 3, the first ice tray 11 and the second ice tray 12 have different ice chamber shapes, and the size of one ice produced in the ice chamber 11a of the first ice tray is 1 ml. The volume of one piece of ice produced in the ice compartment 12a of the dish is 8 ml, so that there is a difference. For example, large ice is characterized by rocks and hemispheres in addition to general cubes, and small ice is characterized by flakes and crashes in addition to general cubes.

第１製氷皿１１と第２製氷皿１２はともに駆動装置１３に連結されており、駆動装置１３内に内蔵されたモータと減速歯車によってそれぞれ個別に反転動作をし、各製氷皿下方の貯氷容器１４へ脱氷する。駆動装置１３内には各製氷皿１１，１２の位置検知を行うスイッチが内蔵されおり、各製氷皿１１，１２の水平位置、脱氷位置は制御部２１へのスイッチ信号入力によって判断される。 The first ice tray 11 and the second ice tray 12 are both connected to a drive device 13 and individually reversely operated by a motor and a reduction gear incorporated in the drive device 13, and an ice storage container below each ice tray. Deicing to 14. A switch for detecting the position of each ice tray 11, 12 is built in the driving device 13, and the horizontal position and deicing position of each ice tray 11, 12 are determined by a switch signal input to the control unit 21.

また、第１検氷レバー１５ａと第２検氷レバー１５ｂも駆動装置１３の側面に連結されており、駆動装置１３に内蔵された減速歯車に連係して動作する。 Further, the first ice detecting lever 15 a and the second ice detecting lever 15 b are also connected to the side surface of the driving device 13 and operate in conjunction with a reduction gear incorporated in the driving device 13.

通常、第１検氷レバー１５ａは貯氷容器の区画１４ａの上方に、第２検氷レバー１５ｂは区画１４ｂの上方に待機しており、第１検氷レバー１５ａは第１製氷皿１１の脱氷動作と同時に貯氷容器の区画１４ａ内に対し進入と退出を行い、区画１４ａ内へ所定位置を越えて進入したときは駆動装置１３内で第１検氷レバー１５ａに対応したスイッチが作動し、制御部２１へのスイッチ信号入力によって区画１４ａ内の氷量が不足していることを検知する。 Usually, the first ice detecting lever 15a is waiting above the compartment 14a of the ice storage container, the second ice detecting lever 15b is waiting above the compartment 14b, and the first ice detecting lever 15a is deiced from the first ice tray 11. Simultaneously with the operation, the ice storage container compartment 14a is entered and exited. When the ice storage container 14a is entered beyond the predetermined position, a switch corresponding to the first ice detecting lever 15a is activated in the drive device 13 to control the ice storage container 14a. The switch signal input to the unit 21 detects that the amount of ice in the section 14a is insufficient.

第２検氷レバー１５ｂは第１製氷皿１１の脱氷動作と同時に貯氷容器の区画１４ｂ内に対し進入と退出を行い、区画１４ｂ内へ所定位置を越えて進入したときは駆動装置１３内で第１検氷レバー１５ｂに対応したスイッチが作動し、制御部２１へのスイッチ信号入力によって区画１４ｂ内の氷量が不足していることを検知する。 The second ice detecting lever 15b enters and exits the compartment 14b of the ice storage container simultaneously with the deicing operation of the first ice tray 11, and enters the compartment 14b beyond the predetermined position within the drive device 13. A switch corresponding to the first ice detecting lever 15b is operated, and it is detected by the switch signal input to the control unit 21 that the amount of ice in the section 14b is insufficient.

各製氷皿１１，１２の脱氷動作は、対応する各検氷レバー１５ａ，１５ｂの方向に向かって反転し、各氷室１１ａ，１２ａの開口部が貯氷容器１４の方向に向いたところで、各製氷皿１１，１２を支持する枠体（図示せず）に形成された突起と当って捻られて氷を押し出すことで達成される。 The deicing operation of each ice tray 11, 12 is reversed toward the corresponding ice detecting levers 15 a, 15 b, and each ice making is made when the opening of each ice chamber 11 a, 12 a faces the ice storage container 14. This is achieved by pushing the ice by twisting against a protrusion formed on a frame (not shown) that supports the dishes 11 and 12.

以上のように構成された冷蔵庫について、次にその動作を説明する。 Next, the operation of the refrigerator configured as described above will be described.

第１製氷皿１１，第２製氷皿１２に給水された水が各氷室１１ａ，１２ａ内で凍結し氷の生成が完了すると、各製氷皿１１，１２の外底面に設置された各温度センサー１１ｄ，１２ｄの抵抗値が上昇し製氷が完了したことを制御部２１が認識する。２つの製氷皿１１，１２が同時に製氷を完了した場合は、第１製氷皿１１の脱氷動作を優先する。 When the water supplied to the first ice tray 11 and the second ice tray 12 is frozen in the ice chambers 11a and 12a and the generation of ice is completed, each temperature sensor 11d installed on the outer bottom surface of each ice tray 11 and 12 is used. , 12d increases and the controller 21 recognizes that ice making is completed. When the two ice trays 11 and 12 complete the ice making at the same time, the deicing operation of the first ice tray 11 is prioritized.

第１製氷皿１１で氷が生成されると第１製氷皿１１は駆動装置１３によって第１検氷レバー１５ａの方向へ反転し捻られて、貯氷容器の区画１４ａへ脱氷する。 When ice is generated in the first ice tray 11, the first ice tray 11 is reversed and twisted in the direction of the first ice detecting lever 15 a by the driving device 13 and deiced into the compartment 14 a of the ice storage container.

区画１４ａ内の氷量は第１製氷皿１１の脱氷動作と同時に行うが、区画１４ａ内に氷が十分あるときは、第１検氷レバー１５ａが区画１４ａに進入しても氷に進行を阻止され所定の高さより深く進入できず、駆動装置１３内のスイッチが作動しないので制御部２１は氷が十分であると認識して、脱氷動作の途中で第１製氷皿１１を停止し、今度は水平位置へ復帰させる。 The amount of ice in the compartment 14a is simultaneously with the deicing operation of the first ice tray 11, but when there is enough ice in the compartment 14a, the ice proceeds even if the first ice detecting lever 15a enters the compartment 14a. The control unit 21 recognizes that the ice is sufficient because it is blocked and cannot enter deeper than a predetermined height, and the switch in the driving device 13 does not operate, and stops the first ice tray 11 during the deicing operation, Now return to the horizontal position.

逆に、区画１４ａ内の氷が不足しているときは、第１検氷レバー１５ａが区画１４ａに進入しても氷に進行を阻止されることがなく所定の高さより深く進入でき、駆動装置内のスイッチが動作し制御部２１は区画１４ａ内の氷が不足していると認識して第１製氷皿１１の脱氷動作を継続して脱氷を完了させる。 On the contrary, when the ice in the compartment 14a is insufficient, even if the first ice detecting lever 15a enters the compartment 14a, it can enter deeper than a predetermined height without being prevented from progressing by the ice. The controller 21 recognizes that the ice in the compartment 14a is insufficient, and continues the deicing operation of the first ice tray 11 to complete the deicing.

脱氷の完了は第１製氷皿１１が脱氷位置に到達した時点で駆動装置１３内のスイッチが作動するので制御部２１は脱氷が完了したと認識する。 When the first ice tray 11 reaches the deicing position, the controller 21 recognizes that the deicing is completed because the switch in the driving device 13 is activated.

脱氷が完了すると駆動装置１３は第１製氷皿１１を水平位置へ復帰させる。第１製氷皿１１が水平位置へ復帰すると駆動装置１３内のスイッチが作動するので制御部２１は第１製氷皿１１が水平位置へ復帰したことを認識する。 When the deicing is completed, the driving device 13 returns the first ice tray 11 to the horizontal position. When the first ice tray 11 returns to the horizontal position, the switch in the driving device 13 is activated, so that the control unit 21 recognizes that the first ice tray 11 has returned to the horizontal position.

脱氷して水平位置へ復帰した第１製氷皿１１へは給水装置の給水ポンプ１９によって再び給水タンク１６から給水され、製氷を開始する。 The first ice tray 11 which has been deiced and returned to the horizontal position is again supplied from the water supply tank 16 by the water supply pump 19 of the water supply device, and ice making is started.

第１製氷皿１１への給水が完了すると、第２製氷皿１２の脱氷を行う。第２製氷皿１２で氷が生成されると第２製氷皿１２は駆動装置１３によって第２検氷レバー１５ｂの方向へ反転し捻られて、貯氷容器の区画１４ｂへ脱氷する。 When the water supply to the first ice tray 11 is completed, the second ice tray 12 is deiced. When ice is generated in the second ice tray 12, the second ice tray 12 is inverted and twisted in the direction of the second ice detecting lever 15b by the driving device 13, and deiced to the compartment 14b of the ice storage container.

区画１４ｂ内の氷量は第２製氷皿１２の脱氷動作と同時に行うが、区画１４ｂ内に氷が十分あるときは、第２検氷レバー１５ｂが区画１４ｂに進入しても氷に進行を阻止され所定の高さより深く進入できず、駆動装置１３内のスイッチが作動しないので制御部２１は氷が十分であると認識して、脱氷動作の途中で第２製氷皿１２を停止し、今度は水平位置へ復帰させる。 The amount of ice in the compartment 14b is performed simultaneously with the deicing operation of the second ice tray 12, but if there is enough ice in the compartment 14b, the ice proceeds even if the second ice detecting lever 15b enters the compartment 14b. The control unit 21 recognizes that the ice is sufficient because it is blocked and cannot enter deeper than a predetermined height, and the switch in the driving device 13 does not operate, and stops the second ice tray 12 during the deicing operation, Now return to the horizontal position.

逆に、区画１４ｂ内の氷が不足しているときは、第２検氷レバー１５ｂが区画１４ａに進入しても氷に進行を阻止されることがなく所定の高さより深く進入でき、駆動装置内のスイッチが動作し制御部２１は区画１４ｂ内の氷が不足していると認識して第２製氷皿１２の脱氷動作を継続して脱氷を完了させる。 On the contrary, when the ice in the compartment 14b is insufficient, even if the second ice detecting lever 15b enters the compartment 14a, it can enter deeper than a predetermined height without being blocked by the ice. The controller 21 recognizes that the ice in the compartment 14b is insufficient, and continues the deicing operation of the second ice tray 12 to complete the deicing.

脱氷の完了は第２製氷皿１２が脱氷位置に到達した時点で駆動装置１３内のスイッチが作動するので制御部２１は脱氷が完了したと認識する。 When the deicing is completed, the control unit 21 recognizes that the deicing is completed because the switch in the driving device 13 is activated when the second ice tray 12 reaches the deicing position.

脱氷が完了すると駆動装置１３は第２製氷皿１２を水平位置へ復帰させる。第２製氷皿１２が水平位置へ復帰すると駆動装置１３内のスイッチが作動するので制御部２１は第２製氷皿１２が水平位置へ復帰したことを認識する。 When the deicing is completed, the driving device 13 returns the second ice tray 12 to the horizontal position. When the second ice tray 12 returns to the horizontal position, the switch in the driving device 13 is activated, so that the control unit 21 recognizes that the second ice tray 12 has returned to the horizontal position.

脱氷して水平位置へ復帰した第２製氷皿１２へは給水装置の給水ポンプ１９によって再び給水タンク１６から給水され、製氷を開始する。 The second ice tray 12 which has been deiced and returned to the horizontal position is again supplied from the water supply tank 16 by the water supply pump 19 of the water supply device, and ice making is started.

第２製氷皿１２への給水は、先に第１製氷皿１１へ給水した直後なので切換弁２０は第１パイプ１８ａへ流路を設定しているので、制御部２１は第２製氷皿１２へ給水されるように流路を第２パイプ１８ｂへ設定する。 Since the water supply to the 2nd ice tray 12 is immediately after supplying the 1st ice tray 11 previously, since the switching valve 20 has set the flow path to the 1st pipe 18a, the control part 21 goes to the 2nd ice tray 12. The flow path is set to the second pipe 18b so that water is supplied.

以上のように、本実施の形態の冷蔵庫は、第１製氷皿１１と、第２製氷皿１２と、第１製氷皿１１と第２製氷皿１２をそれぞれ個別に反転させることのできる駆動装置１３と、第１製氷皿１１の下方に設置した貯氷容器の区画１４ａと、第２製氷皿１２の下方に設置した貯氷容器の区画１４ｂと、駆動装置１３によって動作し区画１４ａ内の氷の量を検知する第１検氷レバー１５ａと、駆動装置１３によって動作し区画１４ｂ内の氷の量を検知する第検氷レバー１５ｂとを備えたので、氷を２つの区画１４ａ、１４ｂに貯えることができるうえに各区画に貯えられた氷の量を第１検氷レバー１５ａ、第２検氷レバー１５ｂによってそれぞれ個別に検知できるので、氷の不足した区画を対照に合理的に製氷を行い氷を補充することができる。 As described above, the refrigerator of the present embodiment includes the first ice tray 11, the second ice tray 12, and the drive device 13 that can individually reverse the first ice tray 11 and the second ice tray 12. An ice storage container compartment 14a installed below the first ice tray 11; an ice storage container compartment 14b installed below the second ice tray 12; and the drive device 13 that operates the amount of ice in the compartment 14a. Since the first ice detecting lever 15a for detecting and the first ice detecting lever 15b for detecting the amount of ice in the compartment 14b operated by the driving device 13 are provided, the ice can be stored in the two compartments 14a and 14b. In addition, the amount of ice stored in each compartment can be individually detected by the first ice detection lever 15a and the second ice detection lever 15b. can do.

また、第１製氷皿１１，第２製氷皿１２へのそれぞれの給水経路を個別に設けず、パイプ１８を第１パイプ１８ａ，第２パイプ１８ｂに分割し、切換弁２０によって第１製氷皿１１，第２製氷皿１２へ選択的に給水するので、コンパクトな構成でそれぞれに適量の給水を行うことができる。 Further, the water supply paths to the first ice tray 11 and the second ice tray 12 are not individually provided, the pipe 18 is divided into the first pipe 18 a and the second pipe 18 b, and the first ice tray 11 is switched by the switching valve 20. Since the water is selectively supplied to the second ice tray 12, it is possible to supply an appropriate amount of water in a compact configuration.

また、第１製氷皿１１，第２製氷皿の底面にそれぞれ第１温度センサー１１ｄ，第２温度センサー１２ｄを設けたことによって、それぞれの製氷皿内の水温を適切に検知することができ、給水や製氷終了の検知が過不足なく合理的な形で確実に行われ、信頼性の高い製氷機能を得ることができる。 Further, by providing the first temperature sensor 11d and the second temperature sensor 12d on the bottom surfaces of the first ice tray 11 and the second ice tray, respectively, the water temperature in each ice tray can be detected appropriately, and the water supply In addition, the detection of the completion of ice making is reliably performed in a reasonable manner without excess or deficiency, and a reliable ice making function can be obtained.

また、区画１４ａ，１４ｂは一つの貯氷容器１４を区画壁１４ｃにより区画しただけの簡単な構造で無効部分が少なく、安価に貯氷領域が区画構成できる。また、貯氷容器１４はひとつであるので設置スペースをコンパクトにまとめることができる。 In addition, the compartments 14a and 14b have a simple structure in which one ice storage container 14 is partitioned by the partition wall 14c, so that there are few invalid portions and the ice storage area can be configured at low cost. Further, since the ice storage container 14 is one, the installation space can be compactly gathered.

また、第１製氷皿１１と第２製氷皿１２の氷室１１ａ，１２ａを互いに異なる形状および大きさとしたので、製氷される氷は、氷の使われる場面や用途および冷却する対象に応じて使い分けができ、使い勝手や利便性を高めて食生活などの生活シーンを豊かに演出することができる。 In addition, since the ice chambers 11a and 12a of the first ice tray 11 and the second ice tray 12 have different shapes and sizes, the ice to be made can be used properly according to the scene and use of the ice and the object to be cooled. It is possible to enhance the usability and convenience and produce a rich life scene such as eating habits.

たとえば、一般的な用途にはキューブ状の大きめの氷、ウイスキーなどにはロック状の大きめの氷、料理の飾り付けには半球状の大きめの氷、飲料やサラダの急速冷却にはフレーク状またはクラッシュ状の小さめの氷、水筒などには形状は問わず注水口から入る程度の少し小さめの氷などである。 For example, large ice cubes for general use, large rock ice for whiskey etc., large hemispherical ice for food decoration, flake or crush for quick cooling of beverages and salads The shape of the small ice cubes and water bottles is a little smaller than the water inlet.

さらに、給水ポンプ１９の駆動時間を選択することなどにより給水量を調節する給水量調節手段を付加すれば、それぞれの製氷容量の範囲内で用途や好みに応じて氷の大きさを変えることができ、上述の種々の氷のバリエーションを広げることができる。 Furthermore, if a water supply amount adjusting means for adjusting the water supply amount is selected by selecting the driving time of the water supply pump 19, the size of the ice can be changed according to the application and preference within the range of each ice making capacity. It is possible to expand the above-mentioned various ice variations.

また、区画壁１４ｃの位置を中央にせず、一回当りに製氷される氷の容量差に応じて区画１４ａ，１４ｂの容量を大小区分することにより、容量に応じてバランスのとれた効率のよい貯氷を行うことができる。 In addition, by dividing the capacity of the compartments 14a and 14b according to the difference in the capacity of ice to be made at one time without making the position of the partition wall 14c at the center, the efficiency is well balanced according to the capacity. You can store ice.

また、本実施の形態のように、冷蔵庫に自動製氷装置１０を適用することにより、製氷用の水が冷蔵室２の冷却雰囲気下で予冷されるため製氷室５の冷凍雰囲気下において効率よく製氷され、製氷室５内で個別に２種の氷の管理が行われ、食品や飲料との関係が深い氷の利用の便宜を図ることができる。 Further, as in the present embodiment, by applying the automatic ice making device 10 to the refrigerator, the ice making water is pre-cooled in the cooling atmosphere of the refrigerating chamber 2, so that the ice making is efficiently performed in the freezing atmosphere of the ice making chamber 5. In addition, two types of ice are individually managed in the ice making chamber 5, and the convenience of using ice having a deep relationship with food and beverages can be achieved.

また、製氷室の扉６を引き出せば同時に貯氷容器１４が一体に引き出され、目より下の見渡しやすく取り出しやすい高さで使い勝手を高めることができる。特に本実施の形態のように２種の氷を使い分けするような場合は、個々の貯氷スペースが十分に大きくとれず、比較的狭いスペースでの取り出し操作性や見分け易さが要求されるため、使用者の肘より下方の高さで引き出し式の形態が望ましい。 In addition, if the door 6 of the ice making room is pulled out, the ice storage container 14 is pulled out at the same time, and the usability can be enhanced with a height that is easy to look down and easy to take out. In particular, when two types of ice are used properly as in the present embodiment, each ice storage space cannot be made sufficiently large, and it is required to be easy to distinguish and take out in a relatively small space. A pull-out form is desirable at a height below the user's elbow.

なお、引き出し式の形態については、本実施の形態のような独立した扉６を備えるもののほか、冷凍室の扉の内側にあり貯氷容器１４を引き出せる形態としたものでも近似した使い勝手を確保できる。 As for the pull-out type, in addition to the one provided with the independent door 6 as in the present embodiment, an approximate usability can be ensured even if the ice storage container 14 is provided inside the freezer compartment door.

FIG. 4 is a front view of an automatic ice making device according to Embodiment 2 of the present invention. FIG. 5 is a perspective view showing a driving device of the automatic ice making device of the embodiment.

３１は第１製氷皿１１，第２製氷皿１２の２種類の製氷皿を備えた自動製氷装置である。３２は第１製氷皿１１、第２製氷皿１２を反転させて脱氷させる駆動装置であり、第１製氷皿１１と第２製氷皿１２の間の間隙寸法を広げた配置構成をとっている。 31 is an automatic ice making device provided with two types of ice trays, a first ice tray 11 and a second ice tray 12. Reference numeral 32 denotes a driving device that reverses the first ice tray 11 and the second ice tray 12 and deicing them, and has an arrangement configuration in which the gap between the first ice tray 11 and the second ice tray 12 is widened. .

３３は第１製氷皿１１、第２製氷皿１２の下方に配置され脱氷された氷を貯える貯氷容器であり、第１製氷皿１１、第２製氷皿１２は貯氷容器３３の両端壁近傍にそれぞれ対向するよう配置されている。貯氷容器３３の内部は第１製氷皿１１からの氷を貯える貯氷領域３３ａ（以下、区画３３ａという）と、第２製氷皿１２からの氷を貯える貯氷領域３３ｂ（以下、区画３３ｂという）とに着脱かつ移動可能な区画壁３３ｃによって区画構成されている。 An ice storage container 33 is disposed below the first ice tray 11 and the second ice tray 12 and stores the deiced ice. The first ice tray 11 and the second ice tray 12 are located near both end walls of the ice storage container 33. They are arranged to face each other. The ice storage container 33 has an ice storage area 33a (hereinafter referred to as a section 33a) for storing ice from the first ice tray 11 and an ice storage area 33b (hereinafter referred to as a section 33b) for storing ice from the second ice tray 12. A partition wall 33c that is detachable and movable is defined as a partition.

また、３３ｄは貯氷容器３３の前後壁に複数対設けられた固定リブであり、区画壁３３ｃの両端部を挿入して固定する。 Further, 33d is a plurality of fixing ribs provided on the front and rear walls of the ice storage container 33, and both ends of the partition wall 33c are inserted and fixed.

以上のような構成において、第１製氷皿１１と第２製氷皿１２の一回当りの製氷量に差があるので、区画壁３３ｃを製氷容量の少ない第１製氷皿１１に最も近い位置の固定リブ３３ｄに挿入して固定すれば、区画３３ａは小さく、区画３３ｂは大きくなり、結果として製氷容量に応じた適切な貯氷領域を構成することができる。 In the configuration as described above, since there is a difference in the amount of ice making per one time of the first ice tray 11 and the second ice tray 12, the partition wall 33c is fixed at the position closest to the first ice tray 11 having a small ice making capacity. If the rib 33d is inserted and fixed, the section 33a is small and the section 33b is large. As a result, an appropriate ice storage area corresponding to the ice making capacity can be configured.

また、区画壁３３ｃを他の位置の固定リブ３３ｄに挿入すれば、使用者のニーズに応じて大小２種類の氷の貯氷領域の大きさを調整することができ、使用頻度の高い氷の貯氷容量を増やして利便性を高めることができる。 Further, if the partition wall 33c is inserted into the fixing rib 33d at another position, the size of the ice storage area of two types of large and small ice can be adjusted according to the needs of the user, and ice storage of frequently used ice can be performed. Convenience can be increased by increasing the capacity.

なお、第１製氷皿１１と第２製氷皿１２の間の間隙寸法を広げた配置構成をとっているので、固定リブ３３ｄの位置を選択できる裕度が確保されている。 In addition, since the arrangement | positioning structure which expanded the gap | interval dimension between the 1st ice tray 11 and the 2nd ice tray 12 is taken, the tolerance which can select the position of the fixing rib 33d is ensured.

また、図示しないが切換弁２０を操作して給水経路を経路の固定する製氷選択手段を備えることにより、第１製氷皿１１を選択すればパイプ１８ａのみに給水タンク１６内の水が給水ポンプ１９によって送られ、第１製氷皿１１のみ有効な製氷作用が行われる。一方、第２製氷皿１２を選択すればパイプ１８ｂのみに給水タンク１６内の水が給水ポンプ１９によって送られ、第２製氷皿１２のみ有効な製氷作用が行われる。 Although not shown, by providing ice making selection means for operating the switching valve 20 to fix the water supply path, if the first ice tray 11 is selected, the water in the water supply tank 16 is supplied only to the pipe 18a. Thus, only the first ice tray 11 performs an effective ice making action. On the other hand, if the second ice tray 12 is selected, water in the water supply tank 16 is sent only to the pipe 18b by the water supply pump 19, and only the second ice tray 12 performs an effective ice making operation.

これにより、必要に応じて第１製氷皿１１または第２製氷皿１２のうちどちらか一方の製氷作用を任意に停止させることができ、たとえばどちらか一方の氷しか使わない場合、製氷量がそれほど必要でない場合などに対応することができ、不必要な製氷作用を行うことによる氷の無駄や電力消費の無駄を省くことができる。 As a result, the ice making operation of either the first ice tray 11 or the second ice tray 12 can be arbitrarily stopped as necessary. For example, when only one of the ice trays is used, the ice making amount is not so large. It is possible to cope with cases where it is not necessary, and it is possible to eliminate waste of ice and waste of power consumption due to unnecessary ice making.

なお、図示しないが、駆動装置３２の内部機構の制御により第１製氷皿１１または第２製氷皿１２の一方の製氷皿の脱氷動作を直接停止させるような製氷選択手段を備えたものであっても上述と同様の作用効果を得ることができ、合理的な製氷作用が行える。 Although not shown, it is provided with ice making selection means for directly stopping the deicing operation of one ice making tray of the first ice tray 11 or the second ice tray 12 by controlling the internal mechanism of the driving device 32. However, the same effect as described above can be obtained, and a rational ice making operation can be performed.

また、上述のような製氷選択手段の操作に合わせて、着脱可能な区画壁３３ｃを取り外せば貯氷容器３３の全体を一区画とすることができ、選択した氷が貯氷容器全体に貯えられる。このため、たとえば、選択した氷の需要が多い場合などに常に十分な氷を利用することができ非常に有用である。 Further, by removing the detachable partition wall 33c in accordance with the operation of the ice making selection means as described above, the entire ice storage container 33 can be made into one section, and the selected ice is stored in the entire ice storage container. For this reason, for example, when there is a great demand for selected ice, sufficient ice can always be used, which is very useful.

（実施の形態３）
図６は本発明による実施の形態３の自動製氷装置の駆動装置を示す斜視図である。図６において、４１，４２は第１製氷皿１１，第２製氷皿１２の下方に対向してそれぞれ配置された第１貯氷容器，第２貯氷容器であり、隣接して並べられている。なお、この実施の形態の貯氷容器を冷蔵庫に適用するにあたっては、製氷室５の扉６に連動して一体に引き出される構造でなく、たとえば図示しない冷凍室内の一画に配置されて、冷凍室の扉を開けてそれぞれ個別に引き出される形態などが望ましい。 (Embodiment 3)
FIG. 6 is a perspective view showing a drive device for an automatic ice making device according to Embodiment 3 of the present invention. In FIG. 6, 41 and 42 are the 1st ice storage container and the 2nd ice storage container respectively arrange | positioned facing the downward direction of the 1st ice tray 11 and the 2nd ice tray 12, and are arranged adjacent. When the ice storage container of this embodiment is applied to a refrigerator, it is not a structure that is integrally drawn in conjunction with the door 6 of the ice making chamber 5, but is disposed in a section of a freezing chamber (not shown), for example. It is desirable that the door is opened and pulled out individually.

以上のような構成において、第１製氷皿１１，第２製氷皿１２でそれぞれ製氷された２種類の氷は、第１貯氷容器４１，第２貯氷容器４２内に個別に落下して区分け貯氷される。 In the configuration as described above, the two types of ice made in the first ice tray 11 and the second ice tray 12 respectively fall into the first ice storage container 41 and the second ice storage container 42 and are stored separately. The

このため、使用者は好みの氷を、貯氷容器を選択することによって取り出すことができ、不要な氷まで同時に引き出さなくてもよいので楽に必要な氷を利用できる。また、不要な氷をその都度外気に曝すこともないので氷がとけにくく、貯氷中に氷同士がくっつく不都合なども軽減できる。 For this reason, the user can take out favorite ice by selecting an ice storage container, and it is not necessary to draw out unnecessary ice at the same time, so that necessary ice can be used easily. In addition, since unnecessary ice is not exposed to the outside air each time, it is difficult for the ice to melt, and the inconvenience of ice sticking during ice storage can be reduced.

図７は本発明による実施の形態４の自動製氷装置の正面図である。 (Embodiment 4)
FIG. 7 is a front view of an automatic ice making device according to Embodiment 4 of the present invention.

５１は自動製氷装置であり、一端を給水タンク１６内に連通し他端を二股に分岐したパイプ５２を備え、パイプ５２の分岐端には二つの給水ポンプすなわち第１給水ポンプ５３ａ，第２給水ポンプ５３ｂが接続されている。また、５２ａ，５２ｂは第１給水ポンプ５３ａ，第２給水ポンプ５３ｂに連結され第１製氷皿１１，第２製氷皿１２に送水するための第１パイプ，第２パイプである。 Reference numeral 51 denotes an automatic ice making device, which includes a pipe 52 having one end communicating with the water supply tank 16 and the other end bifurcated. Two pipes, that is, a first water supply pump 53a and a second water supply are provided at the branch end of the pipe 52. A pump 53b is connected. Reference numerals 52a and 52b denote a first pipe and a second pipe, which are connected to the first water supply pump 53a and the second water supply pump 53b and feed water to the first ice tray 11 and the second ice tray 12, respectively.

以上のような構成において、たとえば切換弁のような新たな特別の機能部品を設けることなく、単純に給水ポンプをもうひとつ増設するだけで第１給水ポンプ５３ａの駆動により第１パイプ５２ａを介して第１製氷皿１１に、また第２給水ポンプ５３ｂの駆動により第２パイプ５２ｂを介して第２製氷皿１２に選択的に給水するので、設置スペースの点で制約がなければ、複雑な機能を用いない分給水切換の信頼性はかえって安定し、コスト的にも同一部品の利用でメリットが期待できる。 In the configuration as described above, the first feed water pump 53a is driven through the first pipe 52a simply by adding another feed water pump without providing a new special functional component such as a switching valve. Water is selectively supplied to the first ice tray 11 and to the second ice tray 12 via the second pipe 52b by driving the second water supply pump 53b. The reliability of the water supply switching that is not used is rather stable, and a merit can be expected by using the same parts in terms of cost.

また、第１給水ポンプ５３ａ，第２給水ポンプ５３ｂのうち任意の給水ポンプの駆動を停止する製氷選択手段（図示しない）を備えれば、任意に一方の製氷動作が実質的に停止され、不要な種類の氷がある場合や氷の量を少なくしたい場合に対応でき、氷の無駄や製氷のための電力消費やポンプ駆動音の発生を低減することができる。 Further, if ice making selection means (not shown) for stopping driving of any one of the first water supply pump 53a and the second water supply pump 53b is provided, one ice making operation is arbitrarily stopped and unnecessary. It is possible to cope with the case where there are various types of ice or when it is desired to reduce the amount of ice, and it is possible to reduce waste of ice, power consumption for ice making, and generation of pump drive noise.

FIG. 8 is a front view of an automatic ice making device according to Embodiment 5 of the present invention.

６１は自動製氷装置であり、一端を給水タンク１６内に連通したパイプ６２に切換弁などの流路切換手段を内蔵した切換機能付き給水ポンプ６３を接続し、切換流路出口より第１製氷皿１１，第２製氷皿１２に送水するための第１パイプ６２ａ，第２パイプ６２ｂを接続している。 Reference numeral 61 denotes an automatic ice making device. A water supply pump 63 with a switching function having a built-in flow path switching means such as a switching valve is connected to a pipe 62 having one end communicating with the water supply tank 16, and the first ice tray is connected to the first ice tray from the switching flow path outlet. 11. A first pipe 62a and a second pipe 62b for supplying water to the second ice tray 12 are connected.

以上のような構成において、切換弁機構を備えた流路切換部品を別途設けることなく、切換機能付き給水ポンプ６３の流路を内部切換することにより第１パイプ６２ａを介して第１製氷皿１１に、また第２パイプ６２ｂを介して第２製氷皿１２に選択的に給水するので、全体構成が簡素でスペースが節約でき、組み立て作業も容易にできる。 In the configuration as described above, the first ice tray 11 is switched via the first pipe 62a by internally switching the flow path of the water supply pump 63 with a switching function without separately providing a flow path switching component having a switching valve mechanism. In addition, since the water is selectively supplied to the second ice tray 12 via the second pipe 62b, the overall configuration is simple, the space can be saved, and the assembling work can be facilitated.

Reference numeral 72 denotes an ice tray made of a plastic resin polypropylene and composed of two types of ice making regions. The ice tray 72 has a first ice making region 73 and a second ice making region 74, and the first ice making region 73 has a plurality of ice shapes.

Branched to 79b.

図１０に示すように、第１製氷領域７３と第２製氷領域７４は氷室７３ａ，７４ａの形状が異なり、第１製氷領域７３の氷室７３ａで生成される氷１個の体積は１ｍｌで、第２製氷領域７４の氷室７４ａで生成される氷１個の体積は８ｍｌである。 As shown in FIG. 10, the first ice making region 73 and the second ice making region 74 have different ice chambers 73a, 74a, and the volume of one ice generated in the ice chamber 73a of the first ice making region 73 is 1 ml. 2 The volume of one piece of ice generated in the ice chamber 74a of the ice making region 74 is 8 ml.

製氷皿７２は駆動装置７５に連結されており、駆動装置７５内に内蔵されたモータと減速歯車によってそれぞれ個別に反転動作をし、製氷皿７２の下方の貯氷容器７７へ脱氷する。駆動装置７５内には製氷皿７２の位置検知を行うスイッチが内蔵されおり、製氷皿７２の水平位置、脱氷位置は制御部７９へのスイッチ信号入力によって判断される。 The ice tray 72 is connected to a driving device 75, and individually reverses by a motor and a reduction gear incorporated in the driving device 75, and the ice tray 72 is deiced to the ice storage container 77 below the ice tray 72. A switch for detecting the position of the ice tray 72 is built in the driving device 75, and the horizontal position and deicing position of the ice tray 72 are determined by a switch signal input to the control unit 79.

また、第１検氷レバー７８ａと第２検氷レバー７８ｂも駆動装置７５の側面に連結されており、駆動装置７５に内蔵された減速歯車に連係して動作する。 The first ice detecting lever 78a and the second ice detecting lever 78b are also connected to the side surface of the driving device 75, and operate in conjunction with a reduction gear incorporated in the driving device 75.

通常、第１検氷レバー７８ａは貯氷容器の区画７７ａの上方に、第２検氷レバー７８ｂは区画７７ｂの上方に待機しており、第１検氷レバー７７ａは製氷皿７２の脱氷動作と同時に貯氷容器の区画７７ａ内に対し進入と退出を行い、区画７７ａ内へ所定位置を越えて進入したときは駆動装置７５内で第１検氷レバー７８ａに対応したスイッチが作動し、制御部８０へのスイッチ信号入力によって区画７７ａ内の氷量が不足していることを検知する。 Normally, the first ice detecting lever 78a stands by above the compartment 77a of the ice storage container, the second ice detecting lever 78b stands above the compartment 77b, and the first ice detecting lever 77a performs the deicing operation of the ice tray 72. At the same time, the ice storage container enters and exits the compartment 77a, and when it enters the compartment 77a beyond a predetermined position, a switch corresponding to the first ice detecting lever 78a is activated in the drive device 75, and the controller 80 It is detected that the amount of ice in the section 77a is insufficient by input of a switch signal to.

第２検氷レバー７８ｂは第１製氷領域７３の脱氷動作と同時に貯氷容器の区画７７ｂ内に対し進入と退出を行い、区画７７ｂ内へ所定位置を越えて進入したと
きは駆動装置７５内で第２検氷レバー７８ｂに対応したスイッチが作動し、制御部８０へのスイッチ信号入力によって区画７７ｂ内の氷量が不足していることを検知する。 The second ice detecting lever 78b enters and exits the compartment 77b of the ice storage container simultaneously with the deicing operation of the first ice making region 73, and enters the compartment 77b beyond the predetermined position within the drive device 75. A switch corresponding to the second ice detecting lever 78b is operated, and it is detected by the switch signal input to the control unit 80 that the ice amount in the section 77b is insufficient.

製氷皿７２の脱氷動作は、各検氷レバー７８ａ，７８ｂの方向に向かって反転し、各氷室７３ａ，７４ａの開口部が貯氷容器７７の方向に向いたところで、製氷皿７２を支持する枠体（図示せず）に形成された突起と当って捻られて氷を押し出すことで達成される。 The deicing operation of the ice tray 72 is reversed toward the ice detecting levers 78 a and 78 b, and the frame for supporting the ice tray 72 when the opening of each ice chamber 73 a and 74 a faces the ice storage container 77. This is achieved by pushing the ice by twisting it against a protrusion formed on the body (not shown).

以上のように構成された自動製氷装置について、その動作を説明する。第１製氷領域７３，第２製氷領域７４に給水された水が各氷室７３ａ，７４ａで凍結し氷の生成が完了すると、製氷皿の各製氷領域の外底面に設置された温度センサー７３ｃ、７４ｃの抵抗値が上昇し製氷が完了したことを制御部８０が認識する。 The operation of the automatic ice making device configured as described above will be described. When the water supplied to the first ice making region 73 and the second ice making region 74 is frozen in the ice chambers 73a and 74a and the generation of ice is completed, temperature sensors 73c and 74c installed on the outer bottom surface of each ice making region of the ice tray. The controller 80 recognizes that the ice resistance is increased and the ice making is completed.

第１製氷領域７３、第２製氷領域７４で氷が生成されたことを制御部８０が認識すると、製氷皿７２は駆動装置７５によって反転し捻られて、貯氷容器の区画７７ａ、区画７７ｂへ脱氷する。 When the control unit 80 recognizes that ice has been generated in the first ice making region 73 and the second ice making region 74, the ice tray 72 is reversed and twisted by the driving device 75, and is removed to the compartments 77a and 77b of the ice storage container. Ice.

氷量の検知は製氷皿７２の脱氷動作と同時に行っているので、例えば区画７７ａ、７７ｂ内の氷が不足しているときは、第１検氷レバー７８ａが区画７７ａに進入しても氷に進行を阻止されることがなく所定の高さより深く進入でき、駆動装置７５内のスイッチが動作し制御部８０は区画７７ａ内の氷が不足していると認識する。同様に第２検氷レバー７８ｂが区画７７ｂに進入しても氷に進行を阻止されることがなく所定の高さより深く進入でき駆動装置７５内のスイッチが動作し制御部８０は区画７７ｂ内の氷が不足していると認識し製氷皿７２の脱氷動作を継続して脱氷を完了させる。 Since the amount of ice is detected simultaneously with the deicing operation of the ice tray 72, for example, when the ice in the compartments 77a and 77b is insufficient, the ice is detected even if the first ice detecting lever 78a enters the compartment 77a. Therefore, the control unit 80 recognizes that the ice in the section 77a is insufficient. Similarly, even if the second ice detecting lever 78b enters the section 77b, the ice is not prevented from proceeding and can enter deeper than a predetermined height, the switch in the driving device 75 operates, and the control unit 80 operates in the section 77b. Recognizing that the ice is insufficient, the deicing operation of the ice tray 72 is continued to complete the deicing.

脱氷の完了は製氷皿７２が脱氷位置に到達した時点で駆動装置７５内のスイッチが作動するので制御部８０は脱氷が完了したと認識する。 When the deicing is completed, when the ice tray 72 reaches the deicing position, the switch in the driving device 75 is operated, so that the control unit 80 recognizes that the deicing is completed.

製氷皿７２の脱氷が完了し製氷皿７２が水平位置に戻る途中で第１検氷レバー７８ａ、第２検氷レバー７８ｂはもう一度氷量検知を行う。例えば区画７７ａ，区画７７ｂ内に氷がまだ不足している場合、第１検氷レバー７８ａが区画７７ａに進入しても氷に進行を阻止されることがなく所定の高さより深く進入でき、駆動装置７５内のスイッチが動作し制御部８０は区画７７ａ内の氷が不足していると認識し、同様に第２検氷レバー７８ｂが区画７７ｂに進入しても氷に進行を阻止されることがなく所定の高さより深く進入でき、駆動装置７５内のスイッチが動作し制御部８０は区画７７ｂ内の氷が不足していると認識する。 While the deicing of the ice tray 72 is completed and the ice tray 72 returns to the horizontal position, the first ice detecting lever 78a and the second ice detecting lever 78b detect the ice amount once again. For example, when the ice is still insufficient in the compartment 77a and the compartment 77b, even if the first ice detecting lever 78a enters the compartment 77a, the ice is not prevented from advancing and can enter deeper than a predetermined height and drive. The switch in the device 75 operates and the control unit 80 recognizes that the ice in the section 77a is insufficient, and similarly, even if the second ice detecting lever 78b enters the section 77b, the progress of the ice is prevented. The control unit 80 recognizes that the ice in the section 77b is insufficient.

製氷皿７２の戻り途中での氷量検知が完了すると駆動装置７５は製氷皿７２を水平位置へ復帰させる。製氷皿７２が水平位置へ復帰すると駆動装置７５内のスイッチが作動するので制御部８０は製氷皿７２が水平位置へ復帰したことを認識する。 When the detection of the amount of ice during the return of the ice tray 72 is completed, the driving device 75 returns the ice tray 72 to the horizontal position. When the ice tray 72 returns to the horizontal position, the switch in the driving device 75 is activated, so that the control unit 80 recognizes that the ice tray 72 has returned to the horizontal position.

製氷皿７２の戻り途中の氷量検知で、区画７７ａ、区画７７ｂ内の氷が不足していると認識した制御部８０は給水ポンプ１９によって製氷皿７２の各製氷領域７３，７４へ給水する。第１製氷領域７３への給水は、ポンプ１９からでてくる水を切換弁２０にて第１パイプ７９ａへ導き、第１製氷容器３１へ給水する。 The control unit 80, which has recognized that the ice in the compartment 77a and the compartment 77b is insufficient by detecting the amount of ice during the return of the ice tray 72, supplies water to the ice making areas 73 and 74 of the ice tray 72 by the water supply pump 19. The water supply to the first ice making region 73 is such that the water coming from the pump 19 is guided to the first pipe 79 a by the switching valve 20 and supplied to the first ice making container 31.

同様に、第２製氷領域７４への給水は、ポンプ１９からでてくる水を切換弁２０にて第２パイプ７９ｂへ導き、第２製氷領域７４へ給水する。 Similarly, water supplied to the second ice making region 74 is supplied from the pump 19 to the second pipe 79 b by the switching valve 20 and supplied to the second ice making region 74.

以上のように、脱氷して水平位置へ復帰した製氷皿７２へは給水ポンプ１９によって再び給水され、再び製氷を開始する。 As described above, the ice tray 72 which has been deiced and returned to the horizontal position is again supplied with water by the water supply pump 19, and ice making is started again.

次に、脱氷によって区画７７ａ、区画７７ｂ内に氷が十分になった場合、製氷皿７２の戻り途中の氷量検知で第１検氷レバー７８ａが区画７７ａに進入しても氷に進行を阻止され所定の高さより深く進入できず、駆動装置７５内のスイッチが作動しないので制御部８０は氷が十分であると認識し、同様に第２検氷レバー７８ｂも区画７７ｂに進入しても氷に進行を阻止され所定の高さより深く進入できず、駆動装置７５内のスイッチが作動しないので制御部８０は氷が十分であると認識する。 Next, when the ice is sufficient in the sections 77a and 77b due to deicing, even if the first ice detecting lever 78a enters the section 77a by detecting the amount of ice while the ice tray 72 is returning, the ice proceeds. The control unit 80 recognizes that the ice is sufficient because it is blocked and cannot enter deeper than a predetermined height, and the switch in the driving device 75 does not operate. Similarly, even if the second ice detecting lever 78b enters the section 77b, too. The control unit 80 recognizes that the ice is sufficient because the progress of the ice is blocked and the ice cannot enter deeper than a predetermined height, and the switch in the driving device 75 does not operate.

そして、製氷皿７２が水平位置へ復帰すると、制御部７９は給水ポンプ１９を駆動せず、製氷皿７２を空のままにして３０分間待機する。 When the ice tray 72 returns to the horizontal position, the control unit 79 does not drive the water supply pump 19 and waits for 30 minutes while leaving the ice tray 72 empty.

３０分間の待機が完了すると、製氷皿７２は空のまま脱氷動作を行い、製氷皿７２の水平位置への復帰途中で氷量検知する。このとき貯氷容器７７の区画７７ａ，７７ｂのどちらか一方の氷が不足し、他方の氷が十分であった場合、例えば区画７７ａ内の氷が不足し、区画７７ｂ内の氷が十分であった場合は、製氷皿７２が水平位置へ復帰してからの給水動作において、制御部８０は第１製氷領域７３にのみ水が行くように切換弁２０を作動して第１パイプ７９ａに水を導く。 When waiting for 30 minutes is completed, the ice tray 72 performs the deicing operation while being empty, and the ice amount is detected while the ice tray 72 is returned to the horizontal position. At this time, when one of the ices in the compartments 77a and 77b of the ice storage container 77 is insufficient and the other ice is sufficient, for example, the ice in the compartment 77a is insufficient and the ice in the compartment 77b is sufficient. In this case, in the water supply operation after the ice tray 72 returns to the horizontal position, the control unit 80 operates the switching valve 20 so that water flows only to the first ice making region 73 and guides the water to the first pipe 79a. .

逆に、区画７７ａ内の氷が十分で、区画７７ｂ内の氷が不足している場合は、製氷皿７２が水平位置へ復帰してからの給水動作において、制御部８０は第２製氷領域７４にのみ水が行くように切換弁２０を作動して第２パイプ７９ｂに水を導く。 On the other hand, when the ice in the compartment 77a is sufficient and the ice in the compartment 77b is insufficient, the control unit 80 performs the second ice making region 74 in the water supply operation after the ice tray 72 returns to the horizontal position. The switching valve 20 is actuated so that water flows only to the second pipe 79b.

以上のように、本実施の形態の冷蔵庫は、第１製氷領域７３と第２製氷領域７４からなる製氷皿７２と、製氷皿７２を反転させることのできる駆動装置７５と、第１製氷領域７３の下方に設置した貯氷容器の区画７７ａと、第２製氷領域７４の下方に設置した貯氷容器の区画７７ｂと、駆動装置７５によって動作し区画７７ａ内の氷の量を検知する第１検氷レバー７８ａと、駆動装置７５によって動作し区画７７ｂ内の氷の量を検知する第２検氷レバー７８ｂとを備えたので、氷を２つの区画７７ａ、７７ｂに貯えることができるうえに各区画７７ａ，７７ｂに貯えられた氷の量を第１検氷レバー７８ａ、第２検氷レバー７８ｂによってそれぞれ個別に検知できるので、氷の不足した区画へ氷を補充することができる。 As described above, the refrigerator of the present embodiment includes the ice making tray 72 including the first ice making region 73 and the second ice making region 74, the drive device 75 that can reverse the ice making plate 72, and the first ice making region 73. An ice storage container section 77a installed below the second ice making area 74, an ice storage container section 77b installed below the second ice making area 74, and a first ice detecting lever that is operated by the drive device 75 to detect the amount of ice in the section 77a. 78a and the second ice detecting lever 78b that is operated by the driving device 75 and detects the amount of ice in the section 77b, the ice can be stored in the two sections 77a and 77b, and each section 77a, Since the amount of ice stored in 77b can be individually detected by the first ice detecting lever 78a and the second ice detecting lever 78b, the ice can be replenished to the section lacking ice.

また、製氷皿７２をひとつ用いるのみで、二つの製氷皿を用いなくても２種類の氷を常に満氷状態になるよう製氷し、貯氷容器７７に区分けして貯氷することができるため、駆動装置７５の内部機構を簡略化でき回転軸７６も一本で済むなど小型化を図ることができることと相俟って、コスト低減や設置スペース縮小のメリットが期待できる。 Further, since only one ice tray 72 is used, two types of ice can be made to be always full without using two ice trays, and the ice can be stored separately in the ice storage container 77. Combined with the fact that the internal mechanism of the device 75 can be simplified and the size can be reduced, for example, only one rotating shaft 76 is required, the advantages of cost reduction and installation space reduction can be expected.

なお、本実施の形態の製氷皿７２および貯氷容器７７の配列は、たとえば冷蔵庫の冷凍室内などに設置する場合において、奥行き方向に生じ易い無効スペースを有効活用するために区画７７ａ，区画７７ｂを前後方向になるように並べてもよく、引き出したときの取り出し易さを考慮して左右方向になるように並べてもよい。 Note that the arrangement of the ice tray 72 and the ice storage container 77 according to the present embodiment is arranged in front of and behind the sections 77a and 77b in order to effectively utilize the invalid space that is likely to occur in the depth direction, for example, when installed in the freezer compartment of a refrigerator. You may arrange so that it may become a direction, and may arrange | position so that it may become the left-right direction in consideration of the ease of taking out when pulling out.

以上のような構成において、脱氷時に第１製氷領域８２，第２製氷領域８３からそれぞれ落下する氷は、境界面８４の幅が大きくとられているため、境界面８４を挟んで隣接する第１製氷領域８２および第２製氷領域８３の氷が、貯氷容器の区画壁７７ｃの上端に衝突して他の区画に誤って落下することがなく確実にそれぞれの所定の区画７７ａ，７７ｂ内で貯氷することができる。 In the configuration as described above, the ice falling from the first ice making region 82 and the second ice making region 83 at the time of deicing has a large width of the boundary surface 84. The ice in the first ice making region 82 and the second ice making region 83 collides with the upper end of the partition wall 77c of the ice storage container and does not accidentally fall into the other compartments, so that the ice storage in each predetermined compartment 77a, 77b is ensured. can do.
