Description

この発明は、自動製氷装置を有する冷蔵庫に関するものである。   The present invention relates to a refrigerator having an automatic ice making device.

従来、家庭用の冷凍冷蔵庫などにおいては、一つの給水装置から一つの製氷容器に水を給水して製氷をおこなう自動製氷装置が普及している。しかし、特に夏場などは氷の供給がエンドユーザの消費に追いつかない状況が発生する。   2. Description of the Related Art Conventionally, in home refrigerators and refrigerators, automatic ice making devices that make ice by supplying water from one water supply device to one ice making container have become widespread. However, especially in summer, there are situations where the ice supply cannot keep up with the consumption of end users.

一般的に氷を高速で製氷する場合には冷蔵庫の圧縮機の運転率を上昇させたり冷気攪拌ファンを高速で運転するなどの手法があるが３０〜４０ｍｉｎレベルが限界であり、また氷生成時間が早すぎると氷の割れ、欠けなどが発生してしまい氷の品質を悪化させてしまう。   In general, when ice is made at high speed, there are techniques such as increasing the operating rate of the compressor of the refrigerator or operating the cold stirring fan at high speed, but the level of 30 to 40 min is the limit, and the ice generation time If it is too early, cracks and chipping of the ice will occur, deteriorating the quality of the ice.

そこで氷を生成する製氷容器を複数設けることにより製氷時間は短縮出来なくても製氷能力を増強しユーザへの氷供給をスムーズにする手法があり文献などにで知られている。このような場合、複数の製氷容器への水の供給方法が信頼性確保やコストアップにおいて課題となってくる。   Therefore, there are methods known in the literature, such as providing a plurality of ice-making containers that generate ice, enhancing the ice-making ability and smoothing the ice supply to the user even if the ice-making time cannot be shortened. In such a case, a method of supplying water to a plurality of ice making containers becomes a problem in ensuring reliability and increasing costs.

例えば給水ポンプモータから複数の製氷容器への水供給手段として給水ポンプモータからの吐出経路を複数設けたもの（特許文献１参照）や給水ポンプモータから吐出された一定量の水を一度貯留してその一部分に設けられた複数の小孔から複数の製氷容器に給水する方法（特許文献２参照）などがある。   For example, as a means for supplying water from a water supply pump motor to a plurality of ice making containers, a plurality of discharge paths from the water supply pump motor are provided (see Patent Document 1) or a fixed amount of water discharged from the water supply pump motor is once stored. There is a method of supplying water to a plurality of ice making containers from a plurality of small holes provided in a part thereof (see Patent Document 2).

第１製氷容器１１、第２製氷容器１２へ供給される水を貯めておくための給水タンク１６は、冷蔵室２内に断熱仕切壁１ａ内に少なくとも一部が埋設するように設置されている。給水タンク１６内の水を第１製氷容器１１、第２製氷容器１２に供給するための給水ポンプ１７は、駆動源であるモータ１７ａ、モータ１７ａの軸に取り付けられたマグネット部１７ｂからなり、給水タンク１６外に配置され、給水タンク１６内に配置された端部にマグネット部１７ｄを備えた羽根車１７ｃを回転させて給水動作を行うものである。給水ポンプからの水を第１製氷容器１１、第２製氷容器１２へ導く給水パイプ１８は、水受皿２１に流路として連結あるいは接続されている。水受皿２１には、第１製氷容器１１へ水を供給する吐出パイプ２０ａ、第２製氷容器１２へ水を供給する吐出パイプ２０ｂが設けられており、第１および第２製氷容器１１、１２へ給水するように構成されているものである。制御部２２は駆動装置１３や給水ポンプ１７の駆動や動作を制御する。   A water supply tank 16 for storing water supplied to the first ice making container 11 and the second ice making container 12 is installed in the refrigerator compartment 2 so as to be at least partially embedded in the heat insulating partition wall 1a. . A water supply pump 17 for supplying water in the water supply tank 16 to the first ice making container 11 and the second ice making container 12 includes a motor 17a as a drive source and a magnet portion 17b attached to the shaft of the motor 17a. A water supply operation is performed by rotating an impeller 17c having a magnet portion 17d at an end disposed outside the tank 16 and disposed in the water supply tank 16. A water supply pipe 18 that guides water from the water supply pump to the first ice making container 11 and the second ice making container 12 is connected or connected to the water receiving tray 21 as a flow path. The water receiving tray 21 is provided with a discharge pipe 20 a for supplying water to the first ice making container 11 and a discharge pipe 20 b for supplying water to the second ice making container 12, and to the first and second ice making containers 11 and 12. It is configured to supply water. The control unit 22 controls driving and operation of the driving device 13 and the water supply pump 17.

次に本実施の形態の動作について説明する。第１製氷容器１１、第２製氷容器１２に給水された水は、野菜室３や冷凍室４の背面に設けられた冷却器（図示せず）により生成された冷気が製氷室５に供給されることによって凍結し氷となる。そして、各製氷容器外底面に設置された温度センサ１１ｄ、１２ｄの検知温度が所定温度以下になっていると判断することによって、氷の生成完了を制御部２２が認識する。   Next, the operation of the present embodiment will be described. The water supplied to the first ice making container 11 and the second ice making container 12 is supplied to the ice making room 5 by cold air generated by a cooler (not shown) provided on the back of the vegetable room 3 and the freezing room 4. Freezes into ice. Then, the control unit 22 recognizes the completion of ice generation by determining that the temperature detected by the temperature sensors 11d and 12d installed on the outer bottom surfaces of the ice making containers is equal to or lower than a predetermined temperature.

第１製氷容器１１にて氷の生成が完了すると、駆動装置１３によって製氷容器１１が反転され、製氷容器の開口面が貯氷箱１４の床面方向に向いたところ（反転したところ）で、各製氷容器を支持する枠体（図示せず）に形成された突起に製氷容器１１の一部があたってその部分が固定されるてめ、他の部分が捻られ離氷する。ここで、第１製氷容器１１の離氷動作開始と同時、あるいは、離氷動作開始後に第１検氷レバー１５ａが貯氷箱１４へ下降して行く動作を行い、貯氷箱１４内の貯氷量検知を行い離氷動作の有無を判断している。   When the generation of ice in the first ice making container 11 is completed, the ice making container 11 is inverted by the driving device 13, and the opening surface of the ice making container is directed toward the floor surface of the ice storage box 14 (reversed). A part of the ice-making container 11 hits a protrusion formed on a frame (not shown) that supports the ice-making container so that the part is fixed, and the other part is twisted and deiced. Here, simultaneously with the start of the ice removal operation of the first ice making container 11 or after the start of the ice removal operation, the first ice detecting lever 15a is moved downward to the ice storage box 14 to detect the amount of ice stored in the ice storage box 14. To determine whether or not the de-icing operation is performed.

第１製氷容器１１の離氷が完了すると、駆動装置１３は第１製氷容器１１を元の水平位置にもどす動作を行う。次に、第２製氷容器１２にて氷の生成が完了すると、同様に駆動装置１３によって製氷容器１２が反転され離氷する。第２製氷容器１２の離氷動作開始と同時、あるいは、離氷動作開始後に第２検氷レバー１５ｂが貯氷箱１４へ下降して行く動作を行い、貯氷箱１４内の貯氷量検知を行う。第２製氷容器１２の離氷が完了すると、駆動装置１３は第２製氷容器１２を元の水平位置にもどす動作を行う。   When the ice removal of the first ice making container 11 is completed, the driving device 13 performs an operation of returning the first ice making container 11 to the original horizontal position. Next, when the generation of ice in the second ice making container 12 is completed, the ice making container 12 is similarly inverted by the driving device 13 and deiced. Simultaneously with the start of the ice-breaking operation of the second ice making container 12 or after the start of the ice-breaking operation, the second ice detecting lever 15b is moved downward to the ice storage box 14 to detect the amount of ice stored in the ice storage box 14. When the ice removal of the second ice making container 12 is completed, the driving device 13 performs an operation of returning the second ice making container 12 to the original horizontal position.

第１製氷容器１１、および、第２製氷容器１２の離氷が完了し、元の水平位置にもどると、給水ポンプ１６によって、各製氷容器１１、１２への給水動作が行われ、再び、氷を生成し、上述の如く動作を繰り返すものである。   When the first ice making container 11 and the second ice making container 12 are completely deiced and returned to the original horizontal position, the water supply pump 16 performs a water supply operation to each ice making container 11 and 12, and again ice And the operation is repeated as described above.

検氷レバー１５ａ、１５ｂの何れかの検知貯氷量（貯蔵されている氷の高さ）がある設定以上の場合（以下、この状態を満氷という）は、次回の給水、あるいは、制御部２２によって、離氷動作が停止され、給水ポンプ１６、あるいは、駆動装置１３の動作も停止される。   When the detected ice storage amount (height of stored ice) of any of the ice detecting levers 15a and 15b is greater than a certain setting (hereinafter, this state is called full ice), the next water supply or the control unit 22 Accordingly, the deicing operation is stopped, and the operation of the water supply pump 16 or the driving device 13 is also stopped.

ここで、本実施の形態では、給水パイプ１８は、給水ポンプ１７より吐出された水を水受皿２１の２つの出口２１ａ、２１ｂ、および第１吐出パイプ２０ａ、第２吐出パイプ２０ｂを介して第１製氷容器１１、第２製氷容器１２に略均等となるように給水する構造となっている。ここで、給水パイプ１８の給水ポンプ１７と反対側の出口（端部）は、２つの出口（１８ｅ、１８ｆ）に分割されており、また、水受皿２１内部も２つの貯留部２１ｃ、２１ｄに分割され、この貯留部２１ｃ、２１ｄはそれぞれ出口２１ａ、２１ｂが設けられており、吐出パイプ２０ａ、２０ｂが接続されている。また、給水パイプ１８の分割された２つの出口１８ｅ、１８ｆの開口面積は略同等であり、また、水受け皿２１の２つの出口２１ａ、２１ｂの開口面積も略同等であり、また、吐出パイプ２０ａ、２０ｂの開口面積も略同等となっている。ここで、本実施の形態では、水受け皿２１の２つの出口２１ａ、２１ｂの開口面積と吐出パイプ２０ａ、２０ｂの入口側開口面積は、給水パイプの２つの出口１８ｅ、１８ｆの開口面積よりも大きくしている。   Here, in the present embodiment, the water supply pipe 18 receives the water discharged from the water supply pump 17 through the two outlets 21a and 21b of the water receiving tray 21, and the first discharge pipe 20a and the second discharge pipe 20b. Water is supplied to the first ice making container 11 and the second ice making container 12 so as to be substantially uniform. Here, the outlet (end) on the opposite side of the water supply pipe 17 of the water supply pipe 18 is divided into two outlets (18e, 18f), and the inside of the water receiving tray 21 is also divided into two reservoirs 21c, 21d. The storage parts 21c and 21d are divided and provided with outlets 21a and 21b, respectively, to which discharge pipes 20a and 20b are connected. Moreover, the opening areas of the two outlets 18e and 18f into which the water supply pipe 18 is divided are substantially equal, the opening areas of the two outlets 21a and 21b of the water tray 21 are also substantially equal, and the discharge pipe 20a. , 20b have substantially the same opening area. Here, in this embodiment, the opening area of the two outlets 21a and 21b of the water tray 21 and the opening area of the inlet side of the discharge pipes 20a and 20b are larger than the opening areas of the two outlets 18e and 18f of the water supply pipe. doing.

ここで、給水ポンプ１７から吐出された水は、給水パイプ１８内をすきまなく満水状態で２つの出口１８ｅ、１８ｆまで到達し、水受け皿２１の２つの貯留部２１ｃ、２１ｄに略均等量を吐出する。そして、２つの吐出パイプ２０ａ、２０ｂの流路抵抗が略同等に構成され、しかも水受け皿２１が水平面に対して角度θだけ傾斜して取り付けられるように構成されているので、水受け皿２１内の貯留部２１ｃ、２１ｄにそれぞれ流入した水は、貯留部２１ｃ、２１ｄに残ることなく出口２１ａ、２１ｂを介して２つの吐出パイプ２０ａ、２０ｂに同時に略均等量だけ流れるようになる。   Here, the water discharged from the water supply pump 17 reaches the two outlets 18e and 18f in the water supply pipe 18 without any gaps, and discharges a substantially equal amount to the two storage portions 21c and 21d of the water tray 21. To do. The flow resistance of the two discharge pipes 20a and 20b is configured to be substantially equal, and the water tray 21 is attached to be inclined at an angle θ with respect to the horizontal plane. The water that has flowed into the reservoirs 21c and 21d, respectively, flows into the two discharge pipes 20a and 20b through the outlets 21a and 21b at the same time by substantially equal amounts without remaining in the reservoirs 21c and 21d.

したがって、従来、２つの製氷容器１１、１２に給水するために、複数の給水ポンプを使用して給水ポンプごとに複数の給水経路を設けたり、あるいは、給水ポンプは１個だが、給水ポンプの吐出口を複数に分割して給水経路を複数設けたりしていたが、本実施の形態の製氷装置や冷蔵庫では、給水ポンプおよび給水パイプを一部品で構成しているため、非常に安価に構成されている。さらに、給水経路途中に連結部や接続部が少なく、給水経路が短く構成できるため、給水経路途中の水残りが生じにくく、水垢等の発生を抑制でき、衛生的な製氷装置や冷蔵庫を得ることができる。   Therefore, conventionally, in order to supply water to the two ice making containers 11 and 12, a plurality of water supply pumps are used to provide a plurality of water supply paths for each water supply pump, or there is one water supply pump, but the water supply pump discharges. Although the outlet is divided into a plurality of water supply paths, the ice making device and the refrigerator of the present embodiment are configured at a very low cost because the water supply pump and the water supply pipe are composed of one part. ing. Furthermore, since there are few connection parts and connection parts in the middle of the water supply path, and the water supply path can be configured short, it is difficult for water to remain in the middle of the water supply path, and it is possible to suppress the occurrence of scales and the like to obtain a sanitary ice making device and refrigerator. Can do.

本実施の形態では、水を貯留する１つの給水タンクと、給水タンク内に貯留されている水を複数の製氷容器へ供給する１つの給水ポンプと、給水ポンプに接続されて給水タンク内に貯留された水を複数の製氷容器に供給される給水経路を構成する給水パイプと、を備え、給水パイプは、複数の製氷容器に略均等な水量を給水できるように少なくとも製氷容器側の出口で複数の製氷容器と同数に分割された分割部を備えているので、安価に複数の製氷容器に略均等の水量を給水することができ、また、給水経路内に残留する水分を極力低減させることができるため、水垢等の発生を抑制でき、衛生的で安価な給水装置や冷蔵庫を提供できる。   In the present embodiment, one water tank that stores water, one water pump that supplies water stored in the water tank to a plurality of ice making containers, and a water pump that is connected to the water pump and stored in the water tank. A water supply pipe that constitutes a water supply path through which the supplied water is supplied to a plurality of ice making containers, and the water supply pipes are provided at a plurality of at least outlets on the ice making container side so that a substantially equal amount of water can be supplied to the plurality of ice making containers. As the ice making container is provided with the same number of divided parts, it is possible to supply a substantially equal amount of water to a plurality of ice making containers at low cost and to reduce the water remaining in the water supply path as much as possible. Therefore, generation | occurrence | production of scale etc. can be suppressed and the hygienic and cheap water supply apparatus and refrigerator can be provided.

また、本実施の形態の製氷装置では、上述の如く、給水タンク１６内の水中に設置される羽根車１７ｃをマグネット１７ｄによって回転駆動させるため、従来のように給水経路途中に例えばギヤポンプ等のポンプ手段を設けて水を汲み上げる方法と比較して、空気等の混入の恐れがなく、安定して多量の水を汲み上げる（吐出する）ことが可能である。また、図４に示す如く、本実施の形態では、給水パイプ１８の先端の２つの出口１８ｅ、１８ｆは分岐リブ１８ｇによって給水パイプ１８より２つに分岐されているが、この分岐リブ１０ｇの幅寸法を３ｍｍ以上としているので、確実に分配可能であり、強度（剛性）も充分である。   In the ice making device of the present embodiment, as described above, the impeller 17c installed in the water in the water supply tank 16 is rotationally driven by the magnet 17d. Compared with the method of pumping water by providing means, it is possible to pump (discharge) a large amount of water stably without fear of mixing of air or the like. Further, as shown in FIG. 4, in the present embodiment, the two outlets 18e and 18f at the tip of the water supply pipe 18 are branched into two from the water supply pipe 18 by the branch rib 18g. Since the dimension is 3 mm or more, it can be surely distributed and the strength (rigidity) is sufficient.

さらには、水の表面張力や流体の回折による再合流現象も抑制できるので、略均等量に水を分岐・供給させることができる。また、図５に示す如く、水受皿２１の底面は組み付け時に傾斜するように構成しているので、水受け皿２１内で水は滞留することなく、吐出パイプ２０ａ、２０ｂによって連続的に満たされた状態でそれぞれの製氷皿１１、１２に略均等量の水が供給される。   Furthermore, since the recombination phenomenon due to the surface tension of water and the diffraction of the fluid can be suppressed, water can be branched and supplied in an approximately equal amount. Further, as shown in FIG. 5, the bottom surface of the water tray 21 is configured to be inclined at the time of assembly, so that water does not stay in the water tray 21 and is continuously filled by the discharge pipes 20a and 20b. In the state, a substantially equal amount of water is supplied to each ice tray 11, 12.

よって、本実施の形態の製氷装置では、冷蔵庫が傾いて据付られた場合であっても、給水ポンプ１７から給水パイプ１８および２つの出口１８ｅ、１８ｆは一様に水が満たされた状態で水受け皿２１に吐出され、各吐出パイプ２０ａ、２０ｂの流路面積（流路抵抗）よりが２つの出口１８ｅ、１８ｆの面積（流路抵抗）よりも大きいため、水受け皿２１内に水が残ることなく複数の製氷容器１１、１２へ給水する構造となっており、給水を確実に略均等量に分配可能な構成となっている。   Therefore, in the ice making device according to the present embodiment, the water supply pipe 17 and the two outlets 18e and 18f are uniformly filled with water even when the refrigerator is inclined and installed. Since water is discharged to the tray 21 and the flow area (flow path resistance) of each discharge pipe 20a, 20b is larger than the area (flow path resistance) of the two outlets 18e, 18f, water remains in the water tray 21. In this structure, water is supplied to the plurality of ice making containers 11 and 12, and the water supply can be reliably distributed in an approximately equal amount.

したがって、水受け皿２１内へ水残りがないので、水垢等の発生を抑制できる衛生的な製氷装置、および冷蔵庫を提供できる。また、水受け皿２１を抗菌剤入りの材料とすると、衛生性がさらに高めることができる。また、図では給水パイプ１８の先端の出口１８ｅ、１８ｆが分岐部分（分岐リブ１８ｇ）が２つに分岐した一体部品の例を示したが、この分岐部分（分岐リブ１８ｇ）のみ別部品として構成しても良いし、あるいは、この分岐部分（分岐リブ１８ｇ）のみ別部品としてインサート成形した給水パイプで構成した装置であっても同様の効果を得られる。   Therefore, since there is no water remaining in the water tray 21, a hygienic ice making device and a refrigerator that can suppress the occurrence of scales can be provided. In addition, when the water tray 21 is made of a material containing an antibacterial agent, hygiene can be further improved. Further, in the figure, the outlets 18e and 18f at the tip of the water supply pipe 18 are shown as an example of an integral part in which the branching portion (branching rib 18g) is branched into two, but only this branching portion (branching rib 18g) is configured as a separate part. Alternatively, the same effect can be obtained even in an apparatus constituted by a water supply pipe that is insert-molded as a separate part only for this branch portion (branch rib 18g).

また、給水パイプ１８、水受け皿２１、および、吐出パイプ２０ａ、２０ｂは着脱可能な構成となっており、取り外して洗浄してまた取り付けることができるので、給水経路を構成するすべての部品の清掃が容易であり、衛生性が確保できる。さらに、給水ポンプ１７の部品であり水路中に設置される羽根車１７ｃも取外して洗浄できるので、給水経路の全てが取外し可能であり、清掃が容易にできるものである。   Moreover, since the water supply pipe 18, the water receiving tray 21, and the discharge pipes 20a and 20b are detachable and can be removed and washed and attached, cleaning of all parts constituting the water supply path is possible. Easy and hygienic. Furthermore, since the impeller 17c which is a component of the water supply pump 17 and is installed in the water channel can also be removed and cleaned, the entire water supply path can be removed and cleaning can be easily performed.

また、図１に示すごとく、本実施の形態の冷蔵庫では、給水タンク１６を冷蔵室２と製氷室５の仕切り壁１ａ中に少なくとも一部を埋め込んで冷蔵室２の内容積を大きく有効に確保しているので、埋め込まれている部分の給水タンク１６内の残水量の確認が困難であるが、本実施の形態の冷蔵庫では、たとえば図２に示す如く、給水パイプ１８の給水タンク１６内に配置される部分に、例えば、刻印等によって水位確認手段である水位線１８ａを表示して、給水タンク１６の壁面あるいは蓋などを透明の材料で構成している。本実施の形態では、給水タンク１６から複数の製氷容器１１、１２に給水する給水パイプ１８に水位を確認するための水位確認手段である水位線１８ａを設けたので、使用者（ユーザー）は給水タンク１６の透明材料部分（たとえば給水タンク１６の上部の蓋に設けられた給水タンク内部可視化用透明ののぞき窓より、給水タンク内の残水量を容易に確認できる。したがって、冷蔵室２のドアを開ければ給水タンク１６内の残水量が確認できるので、給水のタイミングを早期に把握でき、氷不足となることがない。また、給水タンク１６から複数の製氷容器１１、１２に給水する給水パイプ１８が着脱可能に構成されているので、使用者が容易に取外せ、清掃でき、衛生的な製氷装置や冷蔵庫が提供できる。   Further, as shown in FIG. 1, in the refrigerator of the present embodiment, the water supply tank 16 is at least partially embedded in the partition wall 1a of the refrigerator compartment 2 and the ice making compartment 5 to ensure a large effective internal volume of the refrigerator compartment 2. Therefore, it is difficult to confirm the amount of remaining water in the water supply tank 16 in the embedded portion. However, in the refrigerator of this embodiment, for example, as shown in FIG. For example, a water level line 18a which is a water level confirmation means is displayed on the portion to be arranged by marking or the like, and the wall surface or lid of the water supply tank 16 is made of a transparent material. In the present embodiment, the water pipe 18 that supplies water to the ice making containers 11 and 12 from the water supply tank 16 is provided with a water level line 18a that is a water level confirmation means for confirming the water level. The transparent material portion of the tank 16 (for example, the amount of remaining water in the water supply tank can be easily confirmed from the transparent observation window for visualizing the inside of the water supply tank provided on the upper cover of the water supply tank 16. If the water supply tank 16 is opened, the amount of water remaining in the water supply tank 16 can be confirmed, so that the timing of water supply can be grasped at an early stage, and there is no shortage of ice, and the water supply pipe 18 for supplying water from the water supply tank 16 to the plurality of ice making containers 11, 12. Since it is comprised so that attachment or detachment is possible, a user can remove easily and can clean and can provide a sanitary ice making apparatus and a refrigerator.

次に、図６〜図９にて製氷装置１０の構成、動作について説明する。図６、図７、図８、図９は本発明の実施の形態１を表す冷蔵庫の製氷室を上から見た上面図である。製氷装置１０は、先に説明したように、第１製氷容器１１、第２製氷容器１２、駆動装置１３、第１検氷レバー１５ａ、第２検氷レバー１５ｂ、貯氷箱１４などによって構成されている。   Next, the configuration and operation of the ice making device 10 will be described with reference to FIGS. 6, 7, 8, and 9 are top views of the ice making chamber of the refrigerator representing the first embodiment of the present invention as seen from above. As described above, the ice making device 10 includes the first ice making container 11, the second ice making container 12, the driving device 13, the first ice detecting lever 15a, the second ice detecting lever 15b, the ice storage box 14, and the like. Yes.

図６において、第１製氷容器１１、第２製氷容器１２は、長手方向が冷蔵庫の前後方向となるような状態で冷蔵庫の巾方向（左右方向）に並列に少なくとも２つ配置（製氷容器並列配置）されており、第１検氷レバー１５ａ、第２検氷レバー１５ｂは、駆動装置１３の両側方よりそれぞれ冷蔵庫手前方向（前面方向）に延びて、製氷容器１１、１２の長手方向の途中（たとえば略中央）で貯氷箱１４の中心方向に屈曲し、貯氷箱の幅方向略中央部まで延びた形状となっている。   In FIG. 6, at least two first ice making containers 11 and second ice making containers 12 are arranged in parallel in the width direction (left and right direction) of the refrigerator in such a state that the longitudinal direction is the front and rear direction of the refrigerator (ice arrangement of ice making containers in parallel). The first ice detecting lever 15a and the second ice detecting lever 15b extend from both sides of the driving device 13 toward the front of the refrigerator (front direction), respectively, and are in the middle of the ice making containers 11 and 12 in the longitudinal direction ( For example, it has a shape that is bent toward the center of the ice storage box 14 and extends to substantially the center in the width direction of the ice storage box.

本実施の形態では、前記複数の製氷容器を冷蔵庫の巾方向に並列に配置し、生成された氷を貯蔵するための貯氷箱を製氷容器下方に配置し、貯氷箱内の貯氷量を検知する貯氷量検知手段を複数個設けたので、貯氷箱内の氷の分布を加味して、貯氷量を確実に検出できる。また、製氷容器を離氷のための反転動作を行わさせる駆動装置を設け、貯氷量検知手段を複数個のレバーにて構成し、駆動装置にて前記貯氷量検知手段の検氷動作も行わせるようにしたので、駆動装置を１箇所に集約でき、製氷装置や冷蔵庫をコンパクトで、且つ、安価に構成できる。   In the present embodiment, the plurality of ice making containers are arranged in parallel in the width direction of the refrigerator, an ice storage box for storing the generated ice is arranged below the ice making container, and the amount of ice stored in the ice storage box is detected. Since a plurality of ice storage amount detecting means are provided, the ice storage amount can be reliably detected in consideration of the ice distribution in the ice storage box. Also, a drive device for performing the reversing operation for deicing the ice making container is provided, the ice storage amount detection means is constituted by a plurality of levers, and the ice storage amount detection means is also operated by the drive device. Since it did in this way, a drive device can be collected in one place and an ice making apparatus and a refrigerator can be comprised compactly and cheaply.

したがって、本実施の形態では、２つの製氷容器に略均等量の水を供給すように給水装置を構成しており、また製氷容器並列配置を行うことによって、貯氷箱１４内の幅方向（左右方向）に対して、製氷容器１１と製氷容器１２とによって製氷される氷の量が略均等となるので、貯氷箱１４内に離氷される冷蔵庫巾方向に対する氷の数のばらつきが発生しにくいので、確実に貯氷量検知（満氷検知）を行うことができる。また、使用者（ユーザー）によって氷が片寄せされた場合などに対しても、検氷レバーが貯氷箱に対して冷蔵庫の幅方向（左右方向）に２つ（第１検氷レバー１５ａ、第２検氷レバー１５ｂ）設けられているので、確実に貯氷量検知（満氷検知）を行うことができる。従って、氷が多く貯まり過ぎ、製氷容器の離氷動作の反転を阻害したり、製氷室上面に氷が引っ掛かり引出し扉が引き出せなくなるといった不具合を防止することができる。   Therefore, in the present embodiment, the water supply device is configured to supply a substantially equal amount of water to the two ice making containers, and by arranging the ice making containers in parallel, the width direction in the ice storage box 14 (left and right) Direction), the amount of ice produced by the ice making container 11 and the ice making container 12 is substantially equal, and therefore the number of ices in the ice storage box 14 is less likely to vary in the width direction of the refrigerator. Therefore, it is possible to reliably detect the amount of stored ice (detection of full ice). In addition, even when the user (user) moves the ice away, there are two ice detection levers in the width direction (left and right direction) of the refrigerator with respect to the ice storage box (the first ice detection lever 15a, the first ice detection lever 15a). 2) The ice detecting lever 15b) is provided, so that it is possible to reliably detect the amount of stored ice (detection of full ice). Accordingly, it is possible to prevent problems such as excessive accumulation of ice, hindering the reversal of the ice removing operation of the ice making container, or the ice being caught on the upper surface of the ice making chamber and the drawer door being unable to be pulled out.

ここで、 図６は検氷レバーが２つ設けられた場合であるが、図７、図８、図９は検氷レバーを１本のみで構成した例である。図７は検氷レバー１５が駆動装置１３の貯氷箱１４の一方の側方より貯氷箱１４の長手方向冷蔵庫前面側に延びて、貯氷箱１４の略中央部で貯氷箱１４の中心方向に折れ曲がり、貯氷箱１４の他方の側方側まで延出するように設けられている。すなわち、検氷レバー１５は、駆動装置の幅方向一端で片持ち支持され、冷蔵庫の長手方向に貯氷箱４の略半分くらいまで設けられて、そこから貯氷箱１４の他端側（反対側の側面側）まで略９０度折れ曲がるように設けられている。   Here, FIG. 6 shows a case where two ice detecting levers are provided, but FIGS. 7, 8, and 9 are examples in which only one ice detecting lever is configured. In FIG. 7, the ice detecting lever 15 extends from one side of the ice storage box 14 of the driving device 13 to the front side of the refrigerator in the longitudinal direction of the ice storage box 14, and bends toward the center of the ice storage box 14 at a substantially central portion of the ice storage box 14. The ice storage box 14 is provided so as to extend to the other side. That is, the ice detecting lever 15 is cantilevered at one end in the width direction of the driving device, and is provided in the longitudinal direction of the refrigerator up to about half of the ice storage box 4, and from there to the other end side (the opposite side) of the ice storage box 14. (Side surface side) is provided to be bent approximately 90 degrees.

また、図７で説明した検氷レバー１５においては、駆動装置の幅方向一端で片持ち支持され、冷蔵庫の長手方向に貯氷箱４の略半分くらいまで設けられて、そこから貯氷箱１４の他端側（反対側の側面側）まで略９０度折れ曲がるように設けられていたが、図８では、検氷レバー１５は、駆動装置の幅方向一端で片持ち支持され、冷蔵庫の長手方向に貯氷箱４の略半分くらいまで設けられて、そこから貯氷箱１４の他端側（反対側の側面側）まで所定角度（例えば約６０度）で折れ曲がるように設けられている。また、図９では、検氷レバー１５が「コ」の字状をしており、「コ」の字状の開口部が駆動装置の幅方向両端の２箇所で両持ち支持され、冷蔵庫の長手方向に貯氷箱４の略半分くらいまで延出する構造となっている。検氷レバー１５を図７や図８や図９のような形状とすることで、より安価に製造でき、しかも図６の場合と同様の効果を得ることができる。   In addition, the ice detecting lever 15 described in FIG. 7 is cantilevered at one end in the width direction of the driving device, and is provided up to about half of the ice storage box 4 in the longitudinal direction of the refrigerator. In FIG. 8, the ice detecting lever 15 is cantilevered at one end in the width direction of the drive device and stored in the longitudinal direction of the refrigerator. About half of the box 4 is provided, and is bent so as to be bent at a predetermined angle (for example, about 60 degrees) from the ice storage box 14 to the other end side (the side surface on the opposite side). In FIG. 9, the ice detecting lever 15 has a “U” shape, and the “U” -shaped openings are supported at both ends at both ends in the width direction of the drive device, thereby The structure extends in the direction to about half of the ice storage box 4. By forming the ice detecting lever 15 as shown in FIG. 7, FIG. 8, or FIG. 9, the ice detecting lever 15 can be manufactured at a lower cost, and the same effect as in the case of FIG. 6 can be obtained.

本実施の形態では、製氷容器を離氷のための反転動作をさせる駆動装置を設け、貯氷量検知手段は、レバーを貯氷箱の前後方向から幅方向に屈曲させて貯氷箱の巾方向略全幅に渡り貯氷量検知を可能なように構成し、駆動装置にて貯氷量検知手段の検氷動作も行わせるようにしており、貯氷箱内の氷の分布を加味して、貯氷量を確実に検出することができる。   In the present embodiment, a drive device that reverses the ice making container for ice removal is provided, and the ice storage amount detection means is bent substantially in the width direction of the ice storage box by bending the lever in the width direction from the front-rear direction of the ice storage box. The ice storage amount can be detected over a long period of time, and the ice detection operation of the ice storage amount detection means is also performed by the drive unit, taking into account the ice distribution in the ice storage box to ensure the ice storage amount Can be detected.

また、図１０は本実施の形態１を表す冷蔵庫の検氷レバーの断面図を示したものである。図において、図６〜図９にて説明した検氷レバー１５、１５ａ、１５ｂの断面形状（図のＢ−Ｂ断面）は、たとえば三角形など断面の上方部に水滴や氷などが貯留したり氷が付着したりしない形状（断面上方部に平面部を設けない形状）としている。すなわち、本実施の形態では、貯氷量検知手段は、断面形状が上部と下部にそれぞれ略平面部を有し、水や氷やごみなどが付着しにくいように、断面上部の略平面部の面積よりも断面下部の略平面部の面積を大きくしたので、検氷レバー１５上に水滴・氷が貯留したり、あるいは氷が付着したりして検氷レバー１５、１５ａ、１５ｂの動作を阻害することがなく、従って、検氷レバーの氷結や検氷レバー上に氷が乗ることなどにより、誤検知（満氷でないのに満氷であると検知する）するといった不具合が発生せず、氷不足を解消できる。   FIG. 10 shows a sectional view of the ice detecting lever of the refrigerator representing the first embodiment. In the figure, the cross-sectional shapes (cross-section BB in the figure) of the ice detecting levers 15, 15a and 15b described in FIGS. 6 to 9 are such that, for example, water drops or ice are stored in the upper part of the cross section such as a triangle. The shape does not adhere to the surface (the shape in which the flat portion is not provided in the upper portion of the cross section). In other words, in the present embodiment, the ice storage amount detection means has a substantially flat portion at the top and bottom of the cross-sectional shape, and the area of the substantially flat portion at the top of the cross section so that water, ice, dust, etc. are difficult to adhere. Since the area of the substantially flat portion at the bottom of the cross section is made larger than that, water droplets / ice are stored on the ice detecting lever 15 or the ice is attached to obstruct the operation of the ice detecting levers 15, 15a, 15b. Therefore, there is no failure such as false detection (detection of full ice when it is not full) due to freezing of the ice detection lever or ice on the ice detection lever. Can be eliminated.

実施の形態２．
以下、本発明の実施の形態２について、図面を用いながら説明する。図１１は本発明の実施の形態２を表す冷蔵庫の正面図である。図１２は本発明の実施の形態２を表す冷蔵庫の製氷装置を上から見た図である。図１３は本発明の実施の形態２を表す冷蔵庫の要部断面図である。図１１において、実施の形態１、図１〜図１０と同等部分は同一の符号を付して説明は省略する。 図において、本実施の形態の冷蔵庫は、冷蔵庫本体１、冷蔵室２、製氷装置１０を備えた製氷室５、製氷室５に隣接する他の温度帯の貯蔵室６であり、本実施の形態では切替室６に相当する。縦仕切り壁５０は製氷室５と切替室６を断熱して縦に仕切る仕切り壁である。また、吹出し口５１は製氷室５に冷気を供給するように構成されている。 Embodiment 2. FIG.
The second embodiment of the present invention will be described below with reference to the drawings. FIG. 11 is a front view of a refrigerator representing the second embodiment of the present invention. FIG. 12 is a top view of the refrigerator ice making device representing Embodiment 2 of the present invention. FIG. 13: is principal part sectional drawing of the refrigerator showing Embodiment 2 of this invention. 11, the same parts as those in the first embodiment and FIGS. 1 to 10 are denoted by the same reference numerals, and the description thereof is omitted. In the figure, the refrigerator of the present embodiment is a refrigerator body 1, a refrigerator compartment 2, an ice making room 5 equipped with an ice making device 10, and a storage room 6 in another temperature zone adjacent to the ice making room 5. Then, it corresponds to the switching chamber 6. The vertical partition wall 50 is a partition wall that insulates the ice making chamber 5 and the switching chamber 6 and partitions them vertically. The outlet 51 is configured to supply cold air to the ice making chamber 5.

吹出し口５１は、２個の製氷容器１１、１２それぞれに対応して２個（５１ａ、５１ｂ）設けられている。もちろん、吹出し口の数は２ヶ以上であってもよいが、本実施の形態では、複数の製氷容器の氷生成速度のばらつきを極力抑制できるようにするために、製氷容器の数だけ同等形状の吹出し口を設けるようにしている。本実施の形態では、複数の製氷容器を設置した製氷室へ冷気を供給する冷気供給口を製氷室に複数個設けているので、製氷室内の温度分布を均一化でき、複数の製氷容器においても氷の生成速度分布を極力均一化できる。   Two outlets 51 (51a, 51b) are provided corresponding to the two ice containers 11 and 12, respectively. Of course, the number of outlets may be two or more, but in this embodiment, in order to suppress the variation in the ice generation speed of the plurality of ice making containers as much as possible, the number of ice making containers is equal. An outlet is provided. In this embodiment, since the ice making chamber has a plurality of cold air supply ports for supplying cold air to the ice making chamber provided with a plurality of ice making containers, the temperature distribution in the ice making chamber can be made uniform. The ice generation rate distribution can be made as uniform as possible.

また、縦仕切り壁５０は冷蔵庫の前後方向（奥行方向）の途中で、駆動装置１３を避けるよう屈曲された形状となっている。複数の製氷容器１１、１２を駆動させる駆動装置１３はどうしても巾方向で大きくなってしまうが、本実施の形態の冷蔵庫では、駆動装置１３が複数の製氷容器１１、１２の配置された幅よりも大きくなる部分だけ縦仕切り壁５０を冷蔵庫の幅方向に隣接する貯蔵室である切替室６側に屈曲させているので、切替室６の内容積減少を最小限に抑えることができる。   Further, the vertical partition wall 50 is bent in the front-rear direction (depth direction) of the refrigerator so as to avoid the driving device 13. The drive device 13 that drives the plurality of ice making containers 11 and 12 inevitably becomes larger in the width direction. However, in the refrigerator of the present embodiment, the drive device 13 is larger than the width in which the plurality of ice making containers 11 and 12 are arranged. Since the vertical partition wall 50 is bent to the switching chamber 6 side that is a storage chamber adjacent in the width direction of the refrigerator, only a portion that becomes larger can reduce the decrease in the internal volume of the switching chamber 6 to a minimum.

すなわち、製氷容器１１、１２および貯氷箱１４を収納する製氷室５と、製氷室５に隣接し、仕切壁５０により仕切られて製氷室５内の温度帯とは別温度帯を形成する貯蔵室（たとえば切替室）６と、製氷容器１１、１２を反転させてねじり離氷させる駆動装置１３と、を備え、駆動装置１３を製氷室５の後方に設け、仕切壁５０が駆動装置１３に干渉しないよう駆動装置１３部分を避けるように屈曲した形状にしているので、仕切壁５０の形状を工夫するだけで、貯蔵室（切替室）６の内容積減少を最小限に抑えることができる。   That is, the ice making chamber 5 that houses the ice making containers 11 and 12 and the ice storage box 14, and the storage chamber that is adjacent to the ice making chamber 5 and partitioned by the partition wall 50 to form a temperature zone different from the temperature zone in the ice making chamber 5. (For example, a switching chamber) 6 and a driving device 13 that inverts the ice making containers 11 and 12 to twist and release ice, the driving device 13 is provided behind the ice making chamber 5, and the partition wall 50 interferes with the driving device 13. Since the shape is bent so as to avoid the drive device 13 portion, a decrease in the internal volume of the storage chamber (switching chamber) 6 can be minimized by simply devising the shape of the partition wall 50.

また、図において、冷蔵室扉２００ａ、２００ｂは観音開きタイプの冷蔵室扉であり、１つの扉の大きさが小さくてすむため、開口面積小、扉振幅小によって使い勝手が向上する。また、図示の如く、本実施の形態の冷蔵庫においては、冷蔵室２および製氷室５と切替室６の扉の分割ラインを略一直線上に配置することが容易であり、使い勝手の向上に加えて意匠性も改善できるものである。   Further, in the figure, the refrigerator compartment doors 200a and 200b are double door type refrigerator compartment doors, and the size of one door can be small, so that the usability is improved by the small opening area and the small door amplitude. Further, as shown in the figure, in the refrigerator of the present embodiment, it is easy to arrange the dividing lines of the doors of the refrigerator compartment 2 and the ice making compartment 5 and the switching compartment 6 on a substantially straight line, in addition to the improvement in usability. Designability can also be improved.

また、図示はしないが、本実施の形態の製氷装置において、製氷容器は肉厚２ｍｍ以下（１ｍｍ以下が好ましい）の樹脂で形成されている。具体的には、製氷容器１１、１２はポリプロピレン等の材料からなり、具体的には、駆動装置１３に連結される部分や、製氷容器１１、１２を支持する枠体（図示せず）に連結する部分、および、離氷時に枠体に形成された突起に当てられる部分等は必要な強度をもたせる必要があり、肉厚１ｍｍ〜３．５ｍｍ（１ｍｍ〜１．５ｍｍ程度が好ましい）となっているが、主要部は樹脂成形時ショートすることなく成形できる下限である０．８ｍｍ〜１ｍｍの肉厚とすれば良い。このようにすると、必要寿命に対する製氷容器自体の強度を確保した必要な板厚を確保でき、さらに板厚を小さくできるので、離氷時に必要なトルクを低減できるようになり、離氷時トルクを減少できることにより、低消費電力となり、また、駆動装置１３のモータ、および、製氷容器１１、１２を支持する枠体の寿命を伸ばすことができ、信頼性を向上できる。   Although not shown, in the ice making device of the present embodiment, the ice making container is made of a resin having a thickness of 2 mm or less (preferably 1 mm or less). Specifically, the ice making containers 11 and 12 are made of a material such as polypropylene, and specifically, connected to a portion connected to the driving device 13 or a frame (not shown) that supports the ice making containers 11 and 12. The part to be applied and the part applied to the protrusion formed on the frame body at the time of deicing must have a necessary strength, and the thickness is 1 mm to 3.5 mm (preferably about 1 mm to 1.5 mm). However, the main part may have a thickness of 0.8 mm to 1 mm, which is the lower limit that can be formed without short-circuiting during resin molding. In this way, it is possible to secure the necessary plate thickness that ensures the strength of the ice making container itself for the required life, and further reduce the plate thickness, so that the torque required during deicing can be reduced, and the torque during deicing can be reduced. By being able to decrease, the power consumption is reduced, and the life of the motor of the driving device 13 and the frame body supporting the ice making containers 11 and 12 can be extended, and the reliability can be improved.

また、実施の形態１では、第１製氷容器１１と第２製氷容器１２は巾寸法は略同等であり、各製氷容器１１、１２には略均等の水が供給されるように給水パイプ１８の出口１８ｅ、１８ｆ（水受皿２１への連結部）、あるいは、水受皿２１の貯留部２１ｃ、２１ｄ、あるいは吐出パイプ２０ａ、２０ｂの流量割合（分割割合、流路抵抗割合）を略均等に設定していたが、本実施の形態の製氷装置においては、第１製氷容器１１と第２製氷容器１２は巾寸法を各々異なるようにしている。この場合、図示はしないが、本実施の形態では、給水パイプ１８の出口１８ｅ、１８ｆ（水受皿２１への連結部）、あるいは、水受皿２１の貯留部２１ｃ、２１ｄ、あるいは吐出パイプ２０ａ、２０ｂの流量割合（分割割合、流路抵抗割合）を適切に設定して、各製氷容器１１、１２に各製氷容器の大きさに適合する適量の水が給水されるように構成されている。すなわち、本実施の形態では、複数の製氷容器１１、１２の巾寸法を少なくとも１つは異なるようにしたので、幅の異なる氷が製氷できる。   In the first embodiment, the first ice making container 11 and the second ice making container 12 have substantially the same width, and the water supply pipe 18 is provided so that substantially equal water is supplied to each ice making container 11, 12. The flow rate ratio (division ratio, flow path resistance ratio) of the outlets 18e and 18f (the connecting portion to the water receiving tray 21), the storage portions 21c and 21d of the water receiving tray 21 or the discharge pipes 20a and 20b is set substantially equal. However, in the ice making device of the present embodiment, the first ice making container 11 and the second ice making container 12 have different width dimensions. In this case, although not shown, in the present embodiment, outlets 18e and 18f of the water supply pipe 18 (connection portions to the water tray 21), storage portions 21c and 21d of the water tray 21 or discharge pipes 20a and 20b. The flow rate ratio (division ratio, flow path resistance ratio) is appropriately set, and each ice making container 11 and 12 is configured to be supplied with an appropriate amount of water suitable for the size of each ice making container. That is, in the present embodiment, since the plurality of ice making containers 11 and 12 have at least one different width dimension, ice with different widths can be made.

また、本実施の形態の製氷装置では、複数の製氷容器１１、１２大きさの設定は、氷生成速度の遅い幅方向サイドに巾狭の製氷容器１１を配置し、氷生成速度の早い幅方向サイドに巾広の製氷容器１２を配置するようにしており、各製氷容器１１、１２における氷生成速度を略同一に設定できる。すなわち、本実施の形態では、複数の製氷容器１１、１２にて生成される氷の形状が各製氷容器ごとに異なるようにしているので、幅の大きさが異なる製氷容器を使用でき、大きさの異なる氷を製氷することもでき、ユーザーの使用内容（料理用、ロック用、水割り用など）によって使い分けができ、ユーザーメリットが向上する。また、図１２に示す如く、各製氷容器にて生成される氷の形状を互いに異なる形状とすれば、氷の使われる場面や用途に応じ使い分けができ、使い勝手や利便性が高まる。   Further, in the ice making device of the present embodiment, the sizes of the plurality of ice making containers 11 and 12 are set by arranging the narrow ice making container 11 on the side in the width direction where the ice generation speed is slow, and the width direction where the ice generation speed is fast. A wide ice making container 12 is arranged on the side, and the ice production speeds in the ice making containers 11 and 12 can be set to be substantially the same. That is, in this embodiment, since the shape of ice generated in the plurality of ice making containers 11 and 12 is different for each ice making container, ice making containers having different widths can be used. Different types of ice can be made, and can be selected according to the user's usage (for cooking, locking, water splitting, etc.), improving user merit. In addition, as shown in FIG. 12, if the shapes of the ice generated in each ice making container are different from each other, they can be used properly according to the scene and usage of the ice, improving usability and convenience.

また、図１１において、１１ｅは製氷容器１１の外底面に取り付けられ、製氷容器１１内水温を検知する温度検知手段である温度センサーであり、あらかじめ、各製氷容器１１、１２内の氷の生成速度を測定して、生成速度が遅い方の製氷容器のもっとも製氷速度の遅い部分の周辺近傍に配置することによって、複数の製氷容器１１、１２を備えた製氷装置であっても、温度検知手段である温度センサー１１ｅを１個設けるだけで、複数の製氷容器１１、１２の製氷完了を確実に検知できるので、簡単な構成でありながら安価にできる。すなわち、本実施の形態では、複数の製氷容器１１、１２のうちの１つの製氷容器にのみ設けられた温度検出手段と、前記温度検出手段の検出値が所定値以下になった場合に製氷完了であると判断する判断手段と、を備えており、温度検知手段である温度センサー１１ｅを１個設けるだけで、複数の製氷容器１１、１２の製氷完了を確実に検知できるので、簡単な構成でありながら安価にできる。   In FIG. 11, 11e is a temperature sensor which is attached to the outer bottom surface of the ice making container 11 and is a temperature detecting means for detecting the water temperature in the ice making container 11, and the ice production speed in each ice making container 11 and 12 is previously set. Even if an ice making device having a plurality of ice making containers 11 and 12 is arranged near the periphery of the slowest ice making speed of the ice making container having the slower production speed, the temperature detecting means Since only one temperature sensor 11e is provided, the completion of ice making in the plurality of ice making containers 11 and 12 can be reliably detected, so that it is possible to reduce the cost with a simple configuration. That is, in the present embodiment, the temperature detection means provided only in one ice making container among the plurality of ice making containers 11 and 12, and the ice making is completed when the detected value of the temperature detecting means becomes a predetermined value or less. And the determination means for determining that the ice making is completed, the completion of ice making of the plurality of ice making containers 11 and 12 can be reliably detected only by providing one temperature sensor 11e as the temperature detecting means. It can be made inexpensively.

また、本実施の形態では、複数の製氷容器の外表面に設けられた複数の温度検出手段１１ｅと、複数の温度検出手段の検出温度に基づいて製氷完了を判断する判断手段２２と、を備え、複数の温度検出手段の検出値をＡＮＤ回路で使用するか、あるいはＯＲ回路で使用するかを選択可能としているので、製氷容器ごとの製氷速度ばらつきに対し、氷が完全に生成される前に離氷動作に入ることを抑制できる信頼性の高い製氷装置や冷蔵庫が得られる。   Further, in the present embodiment, a plurality of temperature detecting means 11e provided on the outer surfaces of the plurality of ice making containers, and a judging means 22 for judging completion of ice making based on the detected temperatures of the plurality of temperature detecting means are provided. Since it is possible to select whether the detection values of a plurality of temperature detection means are used in an AND circuit or an OR circuit, before ice is completely generated against ice making speed variation for each ice making container A highly reliable ice making device and refrigerator that can prevent entry into the ice removal operation can be obtained.

また、図１３は本発明の実施の形態２を表す製氷装置を備えた冷蔵庫の要部断面図である。図において、実施の形態１、図１〜図１２と同等部分は同一の符号を付して説明は省略する。   Moreover, FIG. 13 is principal part sectional drawing of the refrigerator provided with the ice making apparatus showing Embodiment 2 of this invention. In the figure, the same parts as those in the first embodiment and FIGS. 1 to 12 are denoted by the same reference numerals, and the description thereof is omitted.

図において、冷蔵庫本体１、および、縦仕切り壁５０には、貯氷箱１４の上端フランジ部１４ａの上方にラップする凸形状部１ｂ、５０ｂが設けられている。従って、図示の如く、製氷容器１１、１２を図中矢印のごとく、それぞれ外向きに回転させて離氷させるような場合でも、離氷された氷および氷の破片が、貯氷箱１４とから外部に飛び出そうとしても覆い部である凸形状部１ｂ、５０ｂが設けられている。すなわち、複数の製氷容器１１、１２を冷蔵庫１の巾方向に並列に設置し、複数の製氷容器１１、１２の離氷時に氷の破片等が貯氷箱１４外に落下しないように貯氷箱１４の上端と貯氷箱１４の周辺を構成する仕切壁１、５０との間を覆う覆い部１ｂ、５０ｂを仕切壁１、５０に備えるようにしているので、離氷された氷および氷の破片が貯氷箱１４の外へ落下するのを防止できる。   In the figure, the refrigerator main body 1 and the vertical partition wall 50 are provided with convex-shaped portions 1 b and 50 b that wrap above the upper end flange portion 14 a of the ice storage box 14. Accordingly, as shown in the figure, even when the ice making containers 11 and 12 are rotated outward as indicated by arrows in the drawing, the deiced ice and ice fragments are separated from the ice storage box 14 to the outside. Convex-shaped parts 1b and 50b which are cover parts are provided even if they are about to jump out. That is, a plurality of ice making containers 11, 12 are installed in parallel in the width direction of the refrigerator 1, so that ice pieces and the like do not fall outside the ice storage box 14 when the ice making containers 11, 12 are deiced. Since the partition walls 1 and 50 are provided with cover portions 1b and 50b that cover the space between the upper end and the partition walls 1 and 50 that constitute the periphery of the ice storage box 14, the deiced ice and ice fragments are stored in the ice. It can prevent falling out of the box 14.

貯氷箱１４内の底面には、例えばポリエチレン製などの軟性樹脂製シート１４ｆが、貯氷箱１４の幅方向の略全幅を覆うように敷かれている（略全幅にわたって設けられている）ので、製氷容器１１、１２を各々外向きに回転させて離氷させる場合でも、離氷時の氷落下音を低減でき、低騒音の冷蔵庫を提供できる。ここで、軟性樹脂製シート１４ｆは、貯氷箱１４の前後方向の略全長を覆うように敷かれて（略全長にわたって設けられて）いれば、更なる離氷時の氷落下音を低減でき、低騒音の冷蔵庫を提供できる。また、貯氷箱１４の材質を例えばエラストマーなどの反発係数の低いものを用いても離氷時の氷落下音を低減でき、低騒音の冷蔵庫を提供できる。   On the bottom surface of the ice storage box 14, a soft resin sheet 14f made of polyethylene, for example, is laid so as to cover substantially the entire width in the width direction of the ice storage box 14 (is provided over substantially the entire width). Even in the case where the containers 11 and 12 are rotated outward to separate the ice, the sound of falling ice at the time of deicing can be reduced, and a low noise refrigerator can be provided. Here, if the soft resin sheet 14f is laid so as to cover the substantially entire length of the ice storage box 14 in the front-rear direction (provided over substantially the entire length), it can reduce the ice falling sound at the time of further ice detachment, A low noise refrigerator can be provided. Further, even if the ice storage box 14 is made of a material having a low coefficient of restitution, such as an elastomer, it is possible to reduce the ice falling sound at the time of deicing and to provide a low noise refrigerator.
