Description

本発明は、給水タンクから自動製氷装置への給水管路における冷気の流通を遮断した冷蔵庫に関する。   The present invention relates to a refrigerator that blocks the flow of cold air in a water supply line from a water supply tank to an automatic ice making device.

従来、冷蔵庫に搭載された自動製氷装置（51）は、図４に示すように、冷蔵室（46）内に設置された給水タンク（55）内の製氷用水を給水ポンプ（60）を駆動して給水管路（65）に送り込み、断熱壁（45）を貫通して製氷空間に設置した製氷皿（52）内に給水し、製氷が完了した場合は駆動装置により製氷皿（52）を回転しひねることで離氷し貯氷箱内に貯氷するように制御されている。   Conventionally, an automatic ice making device (51) mounted on a refrigerator drives a water supply pump (60) with ice-making water in a water supply tank (55) installed in a refrigerator compartment (46), as shown in FIG. The water is fed into the water supply pipe (65), passes through the heat insulation wall (45), and is supplied to the ice tray (52) installed in the ice making space. When ice making is completed, the ice tray (52) is rotated by the drive unit. The ice is controlled by twisting and stored in the ice storage box.

そして、給水タンク（55）は製氷用水を随時補給するため冷蔵室（46）内から着脱自在に設置されていることから、前記給水管路（65）との連結については、給水タンク（55）の上面開口を閉塞しているタンク蓋（61）の後端に給水ポンプ（60）と連通する給水パイプ（63）を接続し、この給水パイプ（63）の先端を前記給水管路（65）に連結させて給水タンク（65）の後方近傍に配置した水受皿（64）の上面開口に近接するように対向させて配置していた（例えば、特許文献１参照）。   Since the water supply tank (55) is detachably installed from the refrigerator compartment (46) to replenish ice-making water as needed, the water supply tank (55) is connected to the water supply pipe (65). A water supply pipe (63) communicating with the water supply pump (60) is connected to the rear end of the tank lid (61) blocking the upper surface opening of the water supply pipe, and the tip of the water supply pipe (63) is connected to the water supply line (65) The water receiving tray (64) is connected to the rear surface of the water supply tank (65) and is disposed so as to face the upper surface opening of the water receiving tray (64) (see, for example, Patent Document 1).

また、図５に示されているように、給水タンク（75）の縁部と水受皿（84）との間をシール部材（90）でシールする構成（特許文献２参照）も存在する。
特開２００１−０４１６２５号公報 特開２００４−０８４９８０号公報 Further, as shown in FIG. 5, there is a configuration (see Patent Document 2) in which a gap between the edge of the water supply tank (75) and the water receiving tray (84) is sealed with a seal member (90).
JP 2001-041625 A JP 2004-084980 A

しかしながら、上記特許文献１の構成によれば、着脱自在に設置している給水タンク（65）からの給水パイプ（63）の先端部と、この給水パイプ（63）からの製氷水を受けるために給水パイプ（63）の先端径に対してかなり大きく開口させている水受皿（64）の上面開口との間には、必然的に間隙Ｇが形成されるため、この間隙Ｇから給水管路（65）を通して、冷蔵室（46）内の空気が製氷室（48）に流入し、また、冷凍温度に冷却されている製氷室（48）内の冷却空気が冷蔵室（46）内に流入することになる。   However, according to the configuration of Patent Document 1, in order to receive the tip of the water supply pipe (63) from the water supply tank (65) that is detachably installed and the ice making water from the water supply pipe (63) Since a gap G is inevitably formed between the water tray (64) and the upper surface opening of the water receiving tray (64), which is considerably larger than the tip diameter of the water supply pipe (63), a water supply pipe line ( 65), the air in the refrigerator compartment (46) flows into the ice making chamber (48), and the cooling air in the ice making chamber (48) cooled to the freezing temperature flows into the refrigerator compartment (46). It will be.

そして、前述の冷気流の移動により、前者の場合は、冷蔵室（46）のプラス温度の空気が冷凍温度に冷却されている製氷室（48）に流入することで、製氷室（48）内の温度が上昇してしまうばかりでなく、製氷皿（52）部に臨む給水管路（65）の先端部分やその周辺の製氷室（48）部に空気中の水分が霜となって付着し氷結に発展する不具合がある。また、後者の場合は、低温の製氷室（48）内の冷気によって冷蔵室（46）の水受皿（64）や給水タンク（55）の部分が冷却されることで、周辺部品に露付きが生じる弊害がある。   In the former case, the positive temperature air in the refrigeration chamber (46) flows into the ice making chamber (48) cooled to the freezing temperature by the movement of the cold air flow described above, so that the inside of the ice making chamber (48) As well as the temperature of the ice, the moisture in the air adheres to the tip of the water supply pipe (65) facing the ice tray (52) and the ice making chamber (48) around it as frost. There is a defect that develops into freezing. In the latter case, the cold parts in the cold ice making chamber (48) cool the water tray (64) and the water tank (55) in the refrigerator compartment (46), thereby exposing the surrounding parts. There are harmful effects that occur.

特許文献２は、給水タンク（75）自体で水受皿（84）の開口に取り付けたシール部材（90）に当接しシールさせるものであるが、給水タンク（75）の形状は比較的大きなものであり、設置時に給水パイプ（83）の吐出口位置がばらつくことから、水受皿（84）の上部を覆うために給水タンク（75）の本体からの張り出し部が大きくなり、さらに大形化して高価になるばかりでなく、給水を受ける水受皿（84）の開口が必要以上に大きくなり、これに伴ってシール部材（90）も大きなものにせざるを得ない不具合があった。   In Patent Document 2, the water supply tank (75) itself contacts and seals with a seal member (90) attached to the opening of the water tray (84), but the shape of the water supply tank (75) is relatively large. Yes, since the outlet position of the water supply pipe (83) varies during installation, the overhanging part from the main body of the water supply tank (75) becomes larger to cover the upper part of the water tray (84), making it larger and expensive In addition, the opening of the water tray (84) that receives the water supply becomes larger than necessary, and the seal member (90) must be made large accordingly.

本発明は上記の事情を考慮してなされたものであり、簡単な構成で容易に製造でき、さらに、容易、且つ確実に冷蔵室への給水タンクの着脱をおこない適正な給水性能を得ることができるとともに、貯蔵室間の空気の流通を遮断することができる製氷給水機構を有する冷蔵庫を提供することを目的とする。   The present invention has been made in consideration of the above circumstances, can be easily manufactured with a simple configuration, and can easily and reliably attach and detach the water supply tank to the refrigeration room to obtain an appropriate water supply performance. An object of the present invention is to provide a refrigerator having an ice-making water supply mechanism capable of blocking air circulation between storage rooms.

上記課題を解決するために本発明は、冷凍温度空間に設置した自動製氷装置の製氷皿に給水するための給水タンクを冷蔵貯蔵空間に設置し、前記給水タンクからの給水管路を断熱壁を貫通して製氷皿の上面に臨ませた冷蔵庫において、前記給水管路に連結する管部を形成した水受皿を前記給水タンクの側方に配置し、前記給水タンク内から揚水する給水ポンプに連通するとともに前記給水タンクの上面を閉塞するタンク蓋の端部に給水パイプを接続し、前記給水パイプの先端部を前記水受皿の蓋部材に形成した小径開口に斜め上方から挿通させ、前記給水パイプの先端部近傍の外周面に環状の鍔を形成し、前記環状の鍔の外周部と環状のシールパッキンの内側に設けた環状溝とを固着させて、前記シールパッキンを前記給水パイプの先端部近傍に取り付け、前記シールパッキンの下端縁に環状ひれ部を設け、前記環状ひれ部の先端を前記水受皿の前記蓋部材に当接させたことを特徴とするものである。 In order to solve the above problems, the present invention provides a water supply tank for supplying water to an ice tray of an automatic ice making device installed in a freezing temperature space in a refrigerated storage space, and a water supply pipe from the water supply tank is provided with a heat insulating wall. in refrigerator penetrating so as to face the upper surface of the ice tray, communicating with a feed water pump to the water pan forming a tube portion connected to the water supply conduit is arranged on the side of the water supply tank and pumped from the water supply tank wherein the top surface of the water supply tank connected to the water supply pipe to the end portion of the tank lid for closing, by inserting the tip of the water supply pipe obliquely from above into the small-diameter opening formed in the lid member of the water pan as well as, the water supply pipe An annular flange is formed on the outer peripheral surface in the vicinity of the tip of the annular flange, the outer periphery of the annular flange and the annular groove provided inside the annular seal packing are fixed, and the seal packing is attached to the tip of the water supply pipe Near The mounting, the annular fins provided on the lower edge of the seal packing, is characterized in that the abutted against the distal end of the annular fin portion to the lid member of the water pan.

この構成によって、簡単な構成で製氷用の給水機構を安価に製造でき、さらに、冷蔵室への給水タンクの着脱を容易、且つ確実におこない適正な給水性能を得ることができるとともに貯蔵室間の空気の流通を遮断することができる。   With this configuration, a water supply mechanism for ice making can be manufactured at a low cost with a simple configuration, and the water supply tank can be easily and reliably attached to the refrigerator compartment to obtain an appropriate water supply performance. Air circulation can be blocked.

以下、図面に基づき本発明の１実施形態について説明する。図１は、冷蔵庫（１）の縦断面図であり、外箱（２）の内面に断熱材（３）を介して設けた内箱（４）により貯蔵空間を形成し、断熱仕切壁（５）により複数の貯蔵空間に区分している。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view of a refrigerator (1), in which a storage space is formed by an inner box (4) provided via a heat insulating material (3) on the inner surface of an outer box (2), and a heat insulating partition wall (5 ) To divide into multiple storage spaces.

貯蔵空間の最上部には最も使用頻度が多く収納容積も大きい冷蔵室（６）を配置しており、この冷蔵室（６）は、本体の左右にそれぞれ設けたヒンジによって回動自在に枢支する観音開き方式の左右の扉（７）でその前面開口部を開閉自在に閉塞している。   A refrigeration room (6) that is used most frequently and has a large storage capacity is arranged at the top of the storage space. The refrigeration room (6) is pivotally supported by hinges provided on the left and right sides of the main body. The front opening is closed so that it can be opened and closed by the left and right doors (7) of the double door system.

冷蔵室（６）の下部には、断熱仕切壁（５）を介して比較的小容積の製氷室（８）と図示しない温度切替室とを併設しており、その下方には、前記同様の断熱仕切壁を介して野菜などを収納する野菜室（９）を形成し、最下部には、冷凍食品を収納する冷凍室（10）を配している。上記冷蔵室（６）以外のこれら貯蔵室は、その前面開口を閉塞する扉の庫内側に支持枠を設け、この支持枠に保持した収納容器を各貯蔵室側壁に配置したレールによって前後摺動可能とした引き出し方式としている。   A relatively small-capacity ice making chamber (8) and a temperature switching chamber (not shown) are provided in the lower part of the refrigerator compartment (6) via a heat insulating partition wall (5). A vegetable room (9) for storing vegetables and the like is formed through a heat insulating partition wall, and a freezing room (10) for storing frozen food is arranged at the bottom. These storage chambers other than the refrigerator compartment (6) are provided with a support frame inside the door that closes the front opening thereof, and the storage containers held on the support frame slide back and forth by rails arranged on the side walls of the storage chambers. The drawer system is made possible.

前記製氷室（８）には自動的に氷粒を生成する製氷皿（12）を設けた自動製氷装置（11）および生成された氷粒を収納する貯氷箱（13）を設置しており、製氷皿（12）での製氷が完了した場合は、これを回転してひねることで離氷した氷粒を下方の貯氷箱（13）に落下させ貯氷するものであり、空になった製氷皿（12）に対しては、前記冷蔵室（６）の底部の所定位置に設置した給水タンク（15）から給水する。   The ice making chamber (8) is provided with an automatic ice making device (11) provided with an ice tray (12) for automatically generating ice particles and an ice storage box (13) for storing the generated ice particles, When ice making in the ice tray (12) is completed, the ice cubes that have been deiced by rotating and twisting are dropped into the lower ice storage box (13) to store the ice. For (12), water is supplied from a water supply tank (15) installed at a predetermined position at the bottom of the refrigerator compartment (6).

給水タンク（15）の設置部の縦断面図を図２、関係部品の分解斜視図を図３に示すように、前記給水タンク（15）は、透明の合成樹脂で幅狭で冷蔵室（６）の奥行き方向に長い容器状に形成されており、その底部の中央部分には後方に向かって下方傾斜する凹陥部（15ａ）を形成している。   As shown in FIG. 2 and FIG. 3 which is a longitudinal sectional view of an installation portion of the water tank (15) and an exploded perspective view of related parts, the water tank (15) is made of a transparent synthetic resin and is narrow and a refrigerator compartment (6 ) Is formed in a container shape that is long in the depth direction, and a concave portion (15a) that slopes downward toward the rear is formed at the center of the bottom.

この給水タンク（15）は冷蔵室（６）の底面部に配置されるものであって、給水タンク（15）の配設位置に対応する冷蔵室の底面には、前方から後方に向かって傾斜状に突出するガイド凸部（６ａ）が形成されており、配設する際には、給水タンク（15）を冷蔵室（６）の前方から底面に沿って後方へ摺動させることによって、その後方底部が前記ガイド凸部（６ａ）の傾斜面に沿って上方に持ち上がり、後方部分がガイド凸部（６ａ）を乗り越えることで前記凹陥部（15ａ）がガイド凸部（６ａ）にはまり込み移動を阻止される。この嵌合によって給水タンク（15）の後方部分は冷蔵室（６）の底面に当接し、所定位置に設置させるものである。   The water supply tank (15) is disposed on the bottom surface of the refrigerator compartment (6), and the bottom surface of the refrigerator compartment corresponding to the position of the water supply tank (15) is inclined from the front to the rear. A guide protrusion (6a) protruding in a shape is formed. When the guide protrusion (6a) is disposed, the water supply tank (15) is slid rearward along the bottom surface from the front of the refrigerator compartment (6). The bottom part is lifted upward along the inclined surface of the guide convex part (6a), and the rear part gets over the guide convex part (6a), so that the concave part (15a) fits into the guide convex part (6a) and moves. Is prevented. By this fitting, the rear portion of the water supply tank (15) comes into contact with the bottom surface of the refrigerator compartment (6) and is installed at a predetermined position.

給水タンク（15）を冷蔵室（６）の所定位置に設置することによって、その後壁に近接して配置した給水ポンプ（16）が、冷蔵室底部に取り付けたモーター（17）と対向するように位置決めされる。前記給水ポンプ（16）は、片面にマグネット（18）を固着したインペラ（19）と、インペラ（19）を収納するケーシング（20）と、インペラ（19）を回転させる駆動源である前記モーター（17）とから構成されており、前記インペラ（19）のマグネット（18）に対向する側の回転軸にマグネットを設けたモーター（17）の駆動によるマグネットの回転力を、非接触のマグネットカップリング方式で給水ポンプ（16）のマグネットに伝導し、インペラ（19）を回転させて揚水することで給水タンク（15）内の水を汲み出すように作動する。   By installing the water supply tank (15) at a predetermined position in the refrigerator compartment (6), the water supply pump (16) arranged close to the rear wall faces the motor (17) attached to the bottom of the refrigerator compartment. Positioned. The water supply pump (16) includes an impeller (19) having a magnet (18) fixed on one side thereof, a casing (20) that houses the impeller (19), and a motor that is a drive source for rotating the impeller (19) ( 17), and the rotational force of the magnet driven by a motor (17) provided with a magnet on the rotating shaft on the side facing the magnet (18) of the impeller (19) is used as a non-contact magnet coupling. It is transmitted to the magnet of the water supply pump (16) in this way, and the impeller (19) is rotated to pump up the water to operate to pump out the water in the water supply tank (15).

給水ポンプ（16）からの水は、給水タンク（15）の上面開口部を閉塞するタンク蓋（21）の後方部に一体成形されたほぼ逆Ｌ字形状の給水部（21ａ）の一方の下端に着脱可能に結合された揚水管（22）を経由して外部に汲み出され、タンク蓋（21）の前記給水部（21ａ）の後端部に接続された給水パイプ（23）から本体側に固定された水受皿（24）に流入するものであり、給水管路（25）から冷蔵室（６）底面の断熱仕切壁（５）を貫通して製氷室（８）の上面に至り、流出口に対向している製氷皿（12）に流入して製氷動作が開始される。   The water from the water supply pump (16) is supplied from the bottom end of the substantially inverted L-shaped water supply part (21a) integrally formed at the rear part of the tank lid (21) that closes the upper surface opening of the water supply tank (15). Main body side from a water supply pipe (23) pumped to the outside through a pumping pipe (22) detachably coupled to the water supply portion (21a) of the tank lid (21) And flows into the water tray (24) fixed to the water supply pipe (25), penetrates the heat insulating partition wall (5) on the bottom of the refrigerator compartment (6) and reaches the upper surface of the ice making chamber (8), The ice making operation is started by flowing into the ice tray (12) facing the outlet.

そして、前記給水タンク（15）の凹陥部（15ａ）と冷蔵室（６）底面のガイド凸部（６ａ）との嵌合により、給水タンク（15）が所定位置に設置された場合は、給水パイプ（23）の先端部分からの製氷用水が前記水受皿（24）内に流入するように係合するものであり、以下のように構成されている。   And, when the water supply tank (15) is installed at a predetermined position by fitting the recess (15a) of the water supply tank (15) with the guide convex part (6a) on the bottom of the refrigerator compartment (6), It engages so that the water for ice making from the front-end | tip part of a pipe (23) may flow in into the said water receiving tray (24), and is comprised as follows.

水受皿（24）は、給水タンク（15）の側面後方に近接して配置され、給水タンク（15）を着脱する際に前記ガイド凸部（６ａ）との当接によって上下移動する給水パイプ（23）と確実に係合して水を受けるために、その上面開口を広く開口させており、この開口部には所定径の小径開口（26ａ）を形成した蓋部材（26）を配設してこれを閉塞している。   The water receiving tray (24) is disposed close to the rear side of the side surface of the water supply tank (15), and moves up and down by contact with the guide convex portion (6a) when the water tank (15) is attached and detached ( 23) in order to reliably engage with and receive water, the upper surface opening is wide open, and a lid member (26) having a small-diameter opening (26a) having a predetermined diameter is disposed in the opening. This is blocking.

水受皿（24）の下方には管状の接続部（24ａ）を延出形成し、この接続部（24ａ）に給水した水を前記給水管路（25）に導く弾性体からなる延出管（27）を接続している。この延出管（27）は、前記給水管路（25）の上方の冷蔵室（６）側を形成しているガイドパイプ（28）内に、その弾性を利用して所定の重なり代を有するように嵌入することで、水受皿（24）に流入した水を確実に給水管路（25）に導くように作用する。   A tubular connecting portion (24a) is formed to extend below the water receiving tray (24), and an extending tube made of an elastic body that guides water supplied to the connecting portion (24a) to the water supply conduit (25) ( 27) is connected. The extension pipe (27) has a predetermined overlap margin by utilizing its elasticity in the guide pipe (28) forming the refrigerator compartment (6) side above the water supply pipe (25). By inserting in this way, it acts to reliably guide the water flowing into the water receiving tray (24) to the water supply pipe (25).

前記ガイドパイプ（28）は、前記延出管（27）より充分に径大に形成されており、その上端を給水タンク（15）後部の前記モーター（17）などを収納しているケース部材（29）の上部に形成した開口部に固着し、他端を給水管路（25）に接続することで、水受皿（24）および延出管（27）をガイドパイプ（28）とは別体構成にしてこれから着脱可能としており、この構造により、水受皿（24）と延出管（27）とは、本体部分から取り外し庫外に取り出して洗浄ができるようにしている。   The guide pipe (28) is sufficiently larger in diameter than the extension pipe (27), and the upper end of the guide pipe (28) accommodates the motor (17) at the rear of the water supply tank (15) ( 29) Adhering to the opening formed in the upper part of the top and connecting the other end to the water supply pipe (25), the water tray (24) and the extension pipe (27) are separated from the guide pipe (28). From this structure, the water tray (24) and the extension pipe (27) can be removed from the main body and taken out of the storage for cleaning.

前記給水パイプ（23）の水受皿（24）側の先端部近傍の外周面には、前記水受皿の蓋部材（26）の小径開口（26ａ）よりやや径大の環状の鍔（23ａ）を突設しており、この鍔（23ａ）に嵌合する環状溝（30ａ）を形成したシリコンゴムなどの軟質材からなるシールパッキン（30）を固着している。   On the outer peripheral surface in the vicinity of the water tray (24) side end of the water supply pipe (23), an annular flange (23a) having a diameter slightly larger than the small diameter opening (26a) of the lid member (26) of the water tray is provided. A seal packing (30) made of a soft material such as silicon rubber having an annular groove (30a) fitted to the flange (23a) is fixed.

シールパッキン（30）の前記環状溝（30ａ）の下方には、断面ほぼＬ字状の環状のひれ部（30ｂ）を環状に延出させており、給水タンク（15）を前記凹陥部（15ａ）とガイド凸部（６ａ）との係合によって所定位置に設置した場合には、タンク蓋（21）の給水部（21ａ）の後端部に接続された給水パイプ（23）先端部のシールパッキン（30）のひれ部（30ｂ）が水受皿（24）の蓋部材（26）の小径開口（26ａ）に周縁部に上方から当接し、これを押圧して密着する形となるものであり、水受皿（24）に対する開口面積を小さくするとともにシールパッキン（30）も小形化して安価に確実なシール構成を得ることができる。   Below the annular groove (30a) of the seal packing (30), an annular fin portion (30b) having a substantially L-shaped cross section is annularly extended, and the water supply tank (15) is connected to the recessed portion (15a). ) And the guide projection (6a), when installed at a predetermined position, the seal of the tip of the water supply pipe (23) connected to the rear end of the water supply part (21a) of the tank lid (21) The fin part (30b) of the packing (30) comes into contact with the small-diameter opening (26a) of the lid member (26) of the water tray (24) from above, and presses and adheres to it. In addition, the opening area with respect to the water tray (24) can be reduced, and the seal packing (30) can be reduced in size to obtain a reliable sealing structure at low cost.

本発明は上記のように構成されており、水切れなどによって給水タンク（15）を冷蔵室（６）底面の所定位置から取り出した場合は、その凹陥部（15ａ）とガイド凸部（６ａ）との係合を外すように後部をわずかに上方へ持ち上げるだけの従来と同様の動作で給水パイプ（23）およびシールパッキン（30）は水受皿（24）の蓋部材（26）から簡単に離脱させることができるものである。   The present invention is configured as described above, and when the water supply tank (15) is taken out from a predetermined position on the bottom surface of the refrigerator compartment (6) due to running out of water, the recessed portion (15a) and the guide convex portion (6a) The water supply pipe (23) and the seal packing (30) can be easily detached from the lid member (26) of the water receiving tray (24) by the same operation as in the prior art by lifting the rear part slightly upward so as to disengage the water. It is something that can be done.

また、水補給後に設置する場合は、前述のように給水タンク（15）を冷蔵室（６）底面に沿って奥方向に摺動させ、押し込むことでガイド凸部（６ａ）を乗り越え、凹陥部（15ａ）をガイド突部（６ａ）と係合させて所定位置に配置するものであり、押し込むだけの簡単な動作で、自動的に給水パイプ（23）の先端部は水受皿（24）の蓋部材（26）の小径開口（26ａ）と係合し、同時にシールパッキン（30）のひれ部（30ｂ）は給水タンク（15）の自重によって水受皿の蓋部材（26）の周縁部に上方から密着するものであり、従来冷気の通り道になっていた給水パイプ（23）の先端部と水受皿（24）との間における間隙Ｇの発生を防いで、冷蔵室（６）内と製氷室（８）内との冷却温度の相違する貯蔵室間の空気の流通を遮断し、冷気の流通による冷蔵室（６）内の給水タンク（15）近傍の露付き現象や製氷室（８）の温度上昇や着霜、氷結を未然に防ぐことができる。   When installing after replenishing water, slide the water supply tank (15) in the back direction along the bottom of the refrigerator compartment (6) as described above and push it over the guide convex part (6a). (15a) is engaged with the guide protrusion (6a) and placed at a predetermined position, and the tip of the water supply pipe (23) is automatically attached to the water tray (24) by simple operation. The fin (30b) of the seal packing (30) engages with the small-diameter opening (26a) of the lid member (26), and at the same time, the fin (30b) of the seal packing (30) moves upward to the peripheral edge of the lid member (26) of the water tray. The gap G between the front end of the water supply pipe (23) and the water receiving tray (24), which has conventionally been a path for cold air, is prevented, and the inside of the refrigerator compartment (6) and the ice making chamber (8) Shut off the air flow between the storage chambers where the cooling temperature is different from the inside, and cool by the cold air flow. Temperature rise and frosting of the chamber (6) in the water supply tank (15) dew phenomena and ice making room in the vicinity of (8), the freezing can be prevented.

このとき、シールパッキン（30）は給水パイプ（23）側に嵌着させているため、前記シールパッキン（30）を水受皿（24）側へ固定した場合に比し、シールパッキン（30）の高さ寸法分給水タンク（15）を持ち上げる必要がないので、水受皿（24）との離脱動作の際の移動量を少なくできるだけでなく、水受皿（24）側との密着および離脱動作が簡単になり、構造が簡易になるとともに給水パイプ（23）からのシールパッキン（30）自体の着脱も庫外に取り出した後に容易におこなうことができる利点がある。   At this time, since the seal packing (30) is fitted to the water supply pipe (23) side, the seal packing (30) can be compared with the case where the seal packing (30) is fixed to the water tray (24) side. Since there is no need to lift the water supply tank (15) for the height dimension, not only can the amount of movement when detaching from the water pan (24) be reduced, but also close contact with the water pan (24) and easy detachment operation. Thus, the structure is simplified and the seal packing (30) itself can be easily attached and detached from the water supply pipe (23) after being taken out of the cabinet.

なお、前記実施例においては、水受皿（24）の下方に設けた延出管（27）を、ガイドパイプ（28）内に嵌入する構成としたが、このガイドパイプ（28）と前記延出管（27）との間に空気が流通する間隙が形成される場合には、ガイドパイプ（28）の上端部を固定しているケース部材（29）にこの延出管（27）や水受皿との接続部（24ａ）より径大の筒状に形成した前記シールパッキン（30）と同様の軟質材からなるシール体（31）を配設し、このシール体（31）の内面側に環状に突設させた軟質のひれ（31ａ）を水受皿（24）の接続部（24ａ）あるいは延出管（27）の外周面に当接させるようにすればよい。   In the above embodiment, the extension pipe (27) provided below the water tray (24) is fitted into the guide pipe (28). However, the guide pipe (28) and the extension pipe are arranged. If a gap is formed between the pipe (27) and air, the extension pipe (27) or water tray is attached to the case member (29) that fixes the upper end of the guide pipe (28). A seal body (31) made of a soft material similar to the seal packing (30) formed in a cylindrical shape larger in diameter than the connecting portion (24a) is disposed, and an annular surface is provided on the inner surface side of the seal body (31) The soft fins (31a) projecting from the water can be brought into contact with the connection part (24a) of the water tray (24) or the outer peripheral surface of the extension pipe (27).

これにより、水受皿（24）部分における冷蔵室（６）と製氷室（８）との間の冷気流通を遮断できるとともに、水受皿（24）自体の本体からの着脱も容易となり、給水タンク（15）とともに冷蔵庫外に取り出して分解し容易に洗浄することができる。   Thereby, while being able to interrupt | block the cold air | flow distribution between the refrigerator compartment (6) and ice-making room (8) in a water tray (24) part, attachment / detachment from the main body of a water tray (24) itself becomes easy, and a water supply tank ( 15) Can be taken out of the refrigerator and disassembled for easy cleaning.
