家庭用電気冷蔵庫に搭載される自動製氷装置は、製氷のための水を貯留する給水タンクと、前記給水タンクの水を製氷皿へ給水する給水ポンプと、前記製氷皿を捻り変形させて離氷する駆動装置によって構成されている。 An automatic ice maker installed in a household electric refrigerator includes a water supply tank for storing water for ice making, a water supply pump for supplying water from the water supply tank to an ice tray, and twisting and deforming the ice tray to remove ice. It is comprised by the drive device which performs.

従来、家庭用冷蔵庫に搭載されている自動製氷装置は、冷蔵庫本体への搭載に際して冷蔵室と冷凍室を仕切る断熱仕切り壁が冷蔵庫本体に固定された後に組込まれるものであった。 Conventionally, an automatic ice making device mounted on a household refrigerator has been incorporated after the heat insulating partition wall that partitions the refrigerator compartment and the freezer compartment is fixed to the refrigerator body when mounted on the refrigerator body.

また、製氷装置の構成を簡単にし、製造コストを低減するために、給水タンクと給水装置と製氷皿を一体化構成とした冷蔵庫が知られている（例えば、特許文献１参照）。 In addition, in order to simplify the configuration of the ice making device and reduce the manufacturing cost, a refrigerator is known in which a water supply tank, a water supply device, and an ice tray are integrated (see, for example, Patent Document 1).

以下、図面を参照しながら上記特許文献１に開示された従来の自動製氷装置について説明する。 The conventional automatic ice making device disclosed in Patent Document 1 will be described below with reference to the drawings.

図７は、従来の冷蔵庫に使用されている製氷装置の要部断面図である。 FIG. 7 is a cross-sectional view of a main part of an ice making device used in a conventional refrigerator.

図７において、冷凍室１０１内に配置された製氷ユニット１０２は、製氷皿１０３と、氷を貯氷する貯氷箱１０４と、製氷皿１０３に給水する給水ユニット１０５とより構成されている。 In FIG. 7, the ice making unit 102 arranged in the freezer compartment 101 includes an ice making tray 103, an ice storage box 104 for storing ice, and a water supply unit 105 for supplying water to the ice making tray 103.

給水ユニット１０５は、給水タンク１０６と給水弁１０７と給水パイプ１０８を備えており、給水タンク１０６と給水弁１０７を断熱箱１０９の中に配置している。また、断熱箱１０９の一部には、開閉可能な開閉装置１１０を設けている。 The water supply unit 105 includes a water supply tank 106, a water supply valve 107, and a water supply pipe 108, and the water supply tank 106 and the water supply valve 107 are disposed in a heat insulating box 109. An opening / closing device 110 that can be opened and closed is provided in a part of the heat insulating box 109.

以上のように構成された製氷装置は、開閉装置１１０を開けて給水タンク１０６に水を貯め、その後、給水弁１０７が開き、給水パイプ１０８を通って製氷皿１０３に給水されるもので、製氷皿１０３に供給された水は、冷凍室１の冷気にさらされ、凍結し氷を生成することとなる。生成された氷は製氷皿１０３を回動することにより離氷され、製氷皿７の下部の貯氷箱１０４内に落下して貯氷される。
特開平９−７２６４０号公報 The ice making apparatus configured as described above opens the opening / closing device 110 to store water in the water supply tank 106, and then opens the water supply valve 107 to supply water to the ice making tray 103 through the water supply pipe 108.

The generated ice is deiced by rotating the ice tray 103 and falls into the ice storage box 104 below the ice tray 7 to be stored.
Japanese Patent Laid-Open No. 9-72640

しかしながら、上記従来の構成は、製氷ユニット１０２と給水ユニット１０５を一体化し、冷凍室１０１内に配置する関係から、給水ユニット１０２を断熱箱１０９内に設ける等、構成が必然に大きくなってしまい、冷凍食品等の冷凍室１０１への収納量が削減されてしまうものである。 However, in the conventional configuration, the ice making unit 102 and the water supply unit 105 are integrated and disposed in the freezer compartment 101, so that the configuration is inevitably large, such as providing the water supply unit 102 in the heat insulating box 109. The storage amount of the frozen food or the like in the freezer room 101 is reduced.

また、製氷ユニット１０２と給水ユニット１０５が離れた配置であり、両者を位置決め、固定する基盤部材が必要となり、かかる場合においても、給水ユニット１０５の給水パイプ１０８先端と製氷ユニット１０２を構成する製氷皿１０３の位置合わせを精度よく行う必要があり、結果的に組立てに時間を要する構成であった。 Further, the ice making unit 102 and the water supply unit 105 are arranged apart from each other, and a base member for positioning and fixing the both is necessary. Even in such a case, the tip of the water supply pipe 108 of the water supply unit 105 and the ice making tray constituting the ice making unit 102 are required.

A key-shaped locking piece 28 is provided on the base plate 19, the board 19 is engaged with the locking piece 28, and the remaining one side is fixed with a screw 29.

基板１９を固定する構成は、上述の構成に限るものではなく、取付けた状態では動くことがなく、そして、必要に応じて断熱基板３に固定する位置の微調整、あるいは断熱基板３から着脱ができる構造であればよいのもで、周知の構成を採用することができる。 The configuration for fixing the substrate 19 is not limited to the above-described configuration, and the substrate 19 does not move in the mounted state, and can be finely adjusted for the position to be fixed to the heat insulating substrate 3 or attached / detached from the heat insulating substrate 3 as necessary. Any structure that can be used is acceptable, and a well-known configuration can be adopted.

また、製氷装置１は、内部に断熱材２を充填した板状の断熱仕切り壁３０の所定箇所に設けた開口部３１に嵌め込まれている。 Further, the ice making device 1 is fitted into an opening 31 provided at a predetermined position of a plate-like heat insulating partition wall 30 filled with the heat insulating material 2 therein.

断熱仕切り壁３０は、断熱基板３と同様に合成樹脂製の表皮（ケース）内に、例えば発泡ウレタン等の断熱材、あるいは真空断熱材等を充填したものである。 As with the heat insulating substrate 3, the heat insulating partition wall 30 is made by filling a synthetic resin skin (case) with a heat insulating material such as urethane foam or a vacuum heat insulating material.

さらに、断熱仕切り壁３０に設けた開口部３１の内周縁には、開口面積縮小方向に延出する段差部３２が設けられ、また、断熱基板３の周縁には、断熱仕切り壁３０の開口部３１に設けた段差部３２と当接する当接段部３３が設けられている。 Furthermore, a step 32 extending in the direction of reducing the opening area is provided at the inner peripheral edge of the opening 31 provided in the heat insulating partition wall 30, and the opening of the heat insulating partition wall 30 is provided at the peripheral edge of the heat insulating substrate 3.

Formed.

次に、給水パイプ１８を具備する断熱基板３、給水ユニット４、および製氷ユニット５からなる製氷装置の組立てについて説明する。なお、給水ポンプ８に設けられたモータ７の配線、および駆動部２１に設けられたモータ等の配線は、適宜断熱基板３内に引廻されており、接続コネクタ（図示せず）は露出しているものである。また、この組立て手順は、一例であって、この手順に限るものではない。 Next, the assembly of the ice making device including the heat insulating substrate 3 provided with the water supply pipe 18, the water supply unit 4, and the ice making unit 5 will be described. Note that the wiring of the motor 7 provided in the water supply pump 8 and the wiring of the motor etc. provided in the drive unit 21 are appropriately routed in the heat insulating substrate 3, and the connection connector (not shown) is exposed. It is what. Moreover, this assembly procedure is an example and is not limited to this procedure.

組立てに際しては、例えば、図３に示す如く所定間隔あけて位置する一対の支持板４１を具備した作業台４２を用いる。同図の場合であると、給水ユニット４を組立てることができる状態にある。 At the time of assembly, for example, a work table 42 having a pair of support plates 41 positioned at a predetermined interval as shown in FIG. 3 is used. In the case of the same figure, the water supply unit 4 can be assembled.

すなわち、断熱基板３を支持板４１に載置し、係止片１５を利用して給水ポンプ８、給水ノズル９等を具備した給水ケース１０を仮固定し、給水ノズル９と給水パイプ１８の位置確認を行い、給水ケース１０の最終固定を行う。 That is, the heat insulating substrate 3 is placed on the support plate 41, the water supply case 10 including the water supply pump 8, the water supply nozzle 9, etc. is temporarily fixed using the locking piece 15, and the positions of the water supply nozzle 9 and the water supply pipe 18 are fixed. Confirmation is performed and the water supply case 10 is finally fixed.

そして、区画壁１７を適宜手段で取付け、必要に応じて給水タンク１３の装着を行うことにより、給水ユニット４の完成を確認することができる。 And the completion of the water supply unit 4 can be confirmed by attaching the partition wall 17 by an appropriate means and mounting the water supply tank 13 as necessary.

その結果、かかる手順にかかわらず、周囲にゆとりのある空間を確保して給水ユニット４を組立てることができる。 As a result, regardless of the procedure, the water supply unit 4 can be assembled while ensuring a space around it.

次に、製氷ユニット５を取付ける場合は、予め基板１９に、係止片２４、２５を利用して軸支持部２０、駆動部２１を仮固定すると共に、製氷皿２２を組込み、製氷ユニット５の組立てを行う。このとき、必要に応じてネジあるいは嵌合手段等により、製氷ユニット５の基板１８への組付けを完了する構成としてもよい。 Next, when attaching the ice making unit 5, the shaft support portion 20 and the drive portion 21 are temporarily fixed to the substrate 19 in advance using the locking pieces 24 and 25, and the ice making tray 22 is incorporated. Assemble. At this time, it is good also as a structure which completes the assembly | attachment to the board | substrate 18 of the ice making unit 5 with a screw | thread or a fitting means etc. as needed.

上述の作業と並行して断熱基板３を反転し、給水ユニット４が下方に位置するように断熱基板３を支持板４１に載置し、上方となっている面に、予め製氷ユニット５が組込まれた基板１９を載置し、係止片２８を利用して断熱基板３に仮固定を行う。 In parallel with the above-described operation, the heat insulating substrate 3 is inverted, and the heat insulating substrate 3 is placed on the support plate 41 so that the water supply unit 4 is positioned below, and the ice making unit 5 is incorporated in advance on the upper surface. The substrate 19 thus mounted is placed and temporarily fixed to the heat insulating substrate 3 using the locking pieces 28.

そして、製氷皿２２と給水パイプ１８のノズル位置を確認し、基板１９をネジ２９によって断熱壁３に固定することにより、製氷ユニット５の断熱壁３への取付けを終了し、製氷装置１の組立てが完了する。 Then, the nozzle positions of the ice tray 22 and the water supply pipe 18 are confirmed, and the substrate 19 is fixed to the heat insulating wall 3 with screws 29, whereby the attachment of the ice making unit 5 to the heat insulating wall 3 is finished, and the ice making device 1 is assembled. Is completed.

また、製氷皿２２と給水パイプ１８のノズル位置の微調整が必要であれば、ネジ２９による固定を行う前に係止片２８との隙間、係止片２８の変形可能範囲の応力変形等を利用して基板１９を移動し、行うことができる。 Further, if fine adjustment of the nozzle positions of the ice tray 22 and the water supply pipe 18 is necessary, before the fixing with the screw 29, the gap with the locking piece 28, the stress deformation in the deformable range of the locking piece 28, etc. The substrate 19 can be moved and utilized.

なお、基板１９の断熱基板３への固定は、周知の構成であればよく、ネジ止めに限るものでないことは記載するまでもない。 Needless to say, the substrate 19 may be fixed to the heat insulating substrate 3 with a well-known configuration and not limited to screwing.

したがって、かかる手順にかかわらず、製氷ユニット５を、周囲にゆとりある空間を確保した状態で組立てることができる。 Therefore, regardless of such a procedure, the ice making unit 5 can be assembled in a state in which a space is secured around it.

特に、製氷ユニット５を、予め基板１９に組込んでおき、その基板１９を断熱基板３に取付ける手順は、製氷ユニット５の断熱仕切り壁３０への取付け作業を一層容易とすることができるものであるが、基板１９、製氷ユニット５を順次断熱基板３に組込む手順とすることもできるものである。 In particular, the procedure for installing the ice making unit 5 in the board 19 in advance and attaching the board 19 to the heat insulating board 3 can make the work of attaching the ice making unit 5 to the heat insulating partition wall 30 easier. However, the board 19 and the ice making unit 5 can be incorporated into the heat insulating board 3 in sequence.

以上のように、本実施の形態１における製氷装置１は、その組立てに際してゆとりのある空間を確保して作業が行えるため、作業者への負担のかかる作業姿勢が改善でき、その結果、作業の煩雑さの解消が期待でき、組立て品質の安定化をはかることができる。 As described above, since the ice making device 1 according to the first embodiment can perform work while ensuring a space for assembly, the work posture which places a burden on the worker can be improved. The complexity can be expected to be eliminated, and the assembly quality can be stabilized.

また、給水ユニット４においては、断熱基板３に設けたガイド部１４により、給水タンク１３と給水ポンプ８の給水管路における接続の位置規制を行うため、給水経路の形成が円滑に行え、給水タンク１３の装着性の向上をはかることができるものである。 In the water supply unit 4, the position of the connection between the water supply tank 13 and the water supply pump 8 in the water supply pipe line is regulated by the guide portion 14 provided on the heat insulating substrate 3, so that the water supply path can be formed smoothly, and the water supply tank 13 can be improved.

さらに、上記断熱仕切り壁３０を貯蔵装置へ取付けた後、給水ユニット４、製氷ユニット５が一体となった製氷装置１（断熱基板３）を断熱仕切り壁３０の開口部３１へ装着できるため、貯蔵装置の組立て効率を向上することができるものである。 Furthermore, after the heat insulating partition wall 30 is attached to the storage device, the ice making device 1 (heat insulating substrate 3) in which the water supply unit 4 and the ice making unit 5 are integrated can be attached to the opening 31 of the heat insulating partition wall 30. The assembly efficiency of the apparatus can be improved.

また、製氷装置１（断熱基板３）の断熱仕切り壁３０への装着後においても、断熱基板３ごと製氷装置１を取り出すことが可能であるため、製氷装置１全体を取り外しての清掃が可能となり、清掃性の向上とメンテナンス性の向上をはかることができるものである。 In addition, since the ice making device 1 can be taken out together with the heat insulating substrate 3 even after the ice making device 1 (heat insulating substrate 3) is mounted on the heat insulating partition wall 30, the ice making device 1 as a whole can be removed and cleaned. It is possible to improve the cleaning property and the maintenance property.

なお、本実施の形態１においては、予め断熱基板３に、給水ユニット４と製氷ユニット５を取付け、その断熱基板３を断熱仕切り壁３０の開口部３１に取付ける構成としたが、製氷ユニット５あるいは給水ユニット４等の構成の都合で、いずれか一方のみを予め断熱基板３に取付け、その断熱基板３を断熱仕切り壁３０の開口部３１に取付けた状態で、残るユニットを断熱基板３に取付ける構成とすることもできる。 In the first embodiment, the water supply unit 4 and the ice making unit 5 are attached to the heat insulating substrate 3 in advance, and the heat insulating substrate 3 is attached to the opening 31 of the heat insulating partition wall 30, but the ice making unit 5 or For the convenience of the configuration of the water supply unit 4 or the like, only one of them is attached to the heat insulating substrate 3 in advance, and the remaining unit is attached to the heat insulating substrate 3 with the heat insulating substrate 3 attached to the opening 31 of the heat insulating partition wall 30. It can also be.

また、断熱仕切り壁３０に設けた開口部３１と断熱基板３の嵌合を、段差部３２と当接段部３３による密着状態を確保した嵌合としたが、図４に示す如く、開口部３１、断熱基板３の段差部３２および当接段部３３をテーパー面３４、３５とし、それぞれの面密着による嵌合構造としても、同様にあたかも断熱基板３と断熱仕切り壁３０が一体化されたように形成することができる。 Further, the fitting between the opening 31 provided in the heat insulating partition wall 30 and the heat insulating substrate 3 is a fitting in which a close contact state is ensured by the stepped portion 32 and the contact stepped portion 33. As shown in FIG. 31, the stepped portion 32 and the contact stepped portion 33 of the heat insulating substrate 3 are tapered surfaces 34 and 35, and the fitting structure by close contact with each other is as if the heat insulating substrate 3 and the heat insulating partition wall 30 are integrated. Can be formed.

したがって、図４の構成においても図２と同様に組立てることができ、さらに、断熱仕切り壁３０への取付け状態においても、隙間なく断熱仕切り壁３０と一体化された状態となり、かかる断熱仕切り壁３０を、冷却貯蔵装置の貯蔵室（図示せず）を形成する仕切り壁に採用した場合であっても、温度帯の異なる貯蔵室間の熱漏れを抑制することができる。 Therefore, the structure of FIG. 4 can be assembled in the same manner as in FIG. 2, and even when attached to the heat insulating partition wall 30, it is integrated with the heat insulating partition wall 30 without a gap. Even if it is a case where it employ | adopts for the partition wall which forms the storage chamber (not shown) of a cooling storage apparatus, the heat leak between the storage chambers from which a temperature range differs can be suppressed.

特に、図２の構成は、段差部３２と当接段部３３の密着構成により、断熱仕切り壁３０の開口部３１と断熱基板３の接触面積が大きいため、前述の熱漏れ抑制効果が大きいものである。 2 has a large contact area between the opening 31 of the heat insulating partition wall 30 and the heat insulating substrate 3 due to the close contact structure of the stepped portion 32 and the contact stepped portion 33, so that the above-described heat leakage suppressing effect is large. It is.

FIG. 5 is a perspective view of the main body with the door of the refrigerator showing the second embodiment of the present invention removed. FIG. 6 is a perspective view in the middle of assembling the refrigerator main body according to the second embodiment.

ここでは、本発明の冷却貯蔵装置の一例として、一般家庭で使用される冷凍冷蔵庫を例に説明する。また、先の実施の形態１と同じ構成要素については、同一の符号を付して説明する。 Here, a refrigerator-freezer used in a general household will be described as an example of the cooling storage device of the present invention. Further, the same constituent elements as those of the first embodiment will be described with the same reference numerals.

図５、図６において、冷蔵庫本体（以下、本体と称す）５１は、周知の如く一面が開口した断熱性を有する箱を基調とした構成であり、内壁面には、本体５１の内部を複数の貯蔵室である冷蔵室５２と冷凍室５３に仕切るための仕切り壁取付け凹部（本発明の仕切り壁取付け部に相当）５４が設けられている。 5 and 6, a refrigerator main body (hereinafter referred to as a main body) 51 is based on a heat-insulating box with one surface opened as is well known, and a plurality of interiors of the main body 51 are provided on the inner wall surface. A partition wall mounting concave portion (corresponding to the partition wall mounting portion of the present invention) 54 for partitioning into a refrigerating chamber 52 and a freezing chamber 53 is provided.

断熱仕切り壁３０は、その周縁を仕切り壁取付け凹部５４と嵌合することにより、本体５１内に取付けられ、該本体１の内部に冷蔵室５２と冷凍室５３を形成している。 The heat insulating partition wall 30 is attached in the main body 51 by fitting the peripheral edge of the heat insulating partition wall 30 with the partition wall mounting recess 54, and forms a refrigerator compartment 52 and a freezer compartment 53 inside the main body 1.

そして、適宜手段にて断熱仕切り壁３０の本体５１への固定を行い、断熱仕切り壁３０が取出せない状態となって断熱仕切り壁３０の本体５１への組込みが完了する。 Then, the heat insulating partition wall 30 is fixed to the main body 51 by an appropriate means, so that the heat insulating partition wall 30 cannot be taken out, and the incorporation of the heat insulating partition wall 30 into the main body 51 is completed.

次に、製氷装置１の本体５１への組込みについて説明する。 Next, the incorporation of the ice making device 1 into the main body 51 will be described.

製氷装置１の本体５１への組込みは、図６に示す如く、断熱基板３を断熱仕切り壁３０の開口部３１に嵌まり込むように挿入し、完全に嵌め込む前に製氷装置１の電源線類（図示せず）を本体５１側の電源部（コネクタ類等）と接続し、その後断熱基板３を最後まで挿入する。 As shown in FIG. 6, the ice making device 1 is incorporated into the main body 51 by inserting the heat insulating substrate 3 so as to fit into the opening 31 of the heat insulating partition wall 30, and before the ice making device 1 is completely fitted, the power line of the ice making device 1 is inserted. A type (not shown) is connected to the power supply unit (connectors etc.) on the main body 51 side, and then the heat insulating substrate 3 is inserted to the end.

かかる状態において、必要であれば断熱基板３と断熱仕切り壁３０の接続部に、断熱材を介在させることもできる。この場合は、断熱基板３の周壁部に予め断熱材を貼り付け、同様の作業で断熱基板３を断熱仕切り壁３０の開口部３１に嵌合すればよい。 In this state, if necessary, a heat insulating material can be interposed in the connecting portion between the heat insulating substrate 3 and the heat insulating partition wall 30. In this case, a heat insulating material may be pasted on the peripheral wall portion of the heat insulating substrate 3 in advance, and the heat insulating substrate 3 may be fitted into the opening 31 of the heat insulating partition wall 30 by the same operation.

したがって、冷蔵庫の組立てに際し、断熱基板３の断熱仕切り壁３０への取付けを、断熱仕切り壁３０に設けた開口部３１へ断熱基板３を嵌合する構成とすることにより、温度帯が異なる冷蔵室５２と冷凍室５３間の温度漏れ（冷気漏れ）も抑制でき、冷凍冷蔵庫としての品質、信頼性の低下が抑制できるものである。 Therefore, when the refrigerator is assembled, the heat insulating substrate 3 is attached to the heat insulating partition wall 30 by fitting the heat insulating substrate 3 into the opening 31 provided in the heat insulating partition wall 30, so that the refrigerator compartments having different temperature zones are used. The temperature leak (cold air leak) between 52 and the freezer compartment 53 can also be suppressed, and the quality and reliability reduction as a refrigerator-freezer can be suppressed.

また、作業者には、給水ユニット４、製氷ユニット５の断熱仕切り壁３０への取付けに際しての作業負担が軽減され、従来のように限られた狭い空間での製氷装置１の取付け作業および取付け姿勢が改善されるもので、特に、小型、中型の冷蔵庫の場合には、作業姿勢の改善効果が大きく得られ、作業姿勢の負担軽減に伴って作業内容の信頼性を高めることができ、製氷装置の品質、信頼性を高めた冷凍冷蔵庫を得ることができるものである。 Further, the burden on the worker when the water supply unit 4 and the ice making unit 5 are attached to the heat insulating partition wall 30 is reduced, and the ice making device 1 is attached and attached in a limited space as in the prior art. In particular, in the case of small-sized and medium-sized refrigerators, the effect of improving the work posture can be greatly obtained, and the reliability of the work content can be increased as the burden of the work posture is reduced. It is possible to obtain a refrigerator-freezer with improved quality and reliability.

また、製氷装置１は、断熱基板３ごと断熱仕切り壁３０から取り外すことができるため、水が通る経路を構成する部品を取り外して掃除する場合も、限られた空間（冷蔵室５２、冷凍室５３）内に上半身あるいは手指を入れての作業が改善されるもので、ユーザー消費者またはサービスマンの作業負担を軽減できるものである。 In addition, since the ice making device 1 can be removed from the heat insulating partition wall 30 together with the heat insulating substrate 3, even when removing and cleaning parts constituting a path through which water passes, the limited space (the refrigerator compartment 52, the freezer compartment 53). ) Work with the upper body or fingers inside is improved, and the work burden on the user consumer or service person can be reduced.

さらに、収容容積が異なる冷蔵庫への搭載についても、製氷装置１を取付ける断熱基板３または製氷装置１の大きさを変更するのみで対応が可能となり、汎用性を高めることができる。 Furthermore, mounting on refrigerators with different storage volumes can be handled only by changing the size of the heat insulating substrate 3 or the ice making device 1 to which the ice making device 1 is attached, and versatility can be improved.

なお、上述の説明において、製氷装置１の本体５１への組込みの際に、電源線類の接続作業後に断熱基板３を断熱仕切り壁３０の開口部３１へ完全に嵌合することとしたが、電源線類の接続構造によっては、予め製氷装置１（断熱基板３）を断熱仕切り壁３０の開口部３１へ完全に嵌合させ、その断熱仕切り壁３０を本体５１に組込む際に、あるいは組込んだ後に電源線類の接続作業を行う組立て手順とすることもできるものである。 In the above description, when the ice making device 1 is incorporated into the main body 51, the heat insulating board 3 is completely fitted into the opening 31 of the heat insulating partition wall 30 after the connection work of the power supply lines. Depending on the connection structure of the power lines, the ice making device 1 (heat insulating substrate 3) is completely fitted in advance to the opening 31 of the heat insulating partition wall 30 and the heat insulating partition wall 30 is assembled into the main body 51 or built in. After that, it is possible to use an assembling procedure for connecting the power lines.

本発明にかかる自動製氷装置は、例えば冷蔵室と冷凍室を区画する仕切り壁に開口部を設け、その開口部に冷蔵室と冷凍室を区画する断熱基板を有する製氷装置を取付けた構成であり、収容容量の小さな小型冷蔵庫から収容容積が大きな大型の冷蔵庫にわたって広く適用できるものである。 The automatic ice making device according to the present invention has, for example, a configuration in which an opening is provided in a partition wall that partitions a refrigerator compartment and a freezer compartment, and an ice making device having a heat insulating substrate that partitions the refrigerator compartment and the freezer compartment is attached to the opening. The present invention can be widely applied from a small refrigerator having a small storage capacity to a large refrigerator having a large storage capacity.
