Abstract

PROBLEM TO BE SOLVED: To prevent bedewing water produced on an outer bottom face of a drain pan from leaking out of a machine.SOLUTION: An outer bottom face 50 of a drain pan 36 provided below an ice making water tank 30 to receive ice making residual water discharged according to a tilt of the ice making water tank 30 to discharge the ice making residual water from a drain port 38 out of the machine when deicing is performed, is provided with a draining hanging wall 52 extending along an outer periphery. So bedewing water W produced on the outer bottom face 50 is dripped in an ice storage chamber 68 by the hanging wall 52 and never flows out the periphery of the outer bottom face 50.

Description

本発明は、製氷水タンクから排出される製氷残水を受入れて、該製氷残水を製氷機の外部へ排出する排水皿に関するものである。   The present invention relates to a drain tray that receives ice making residual water discharged from an ice making water tank and discharges the ice making residual water to the outside of the ice making machine.

多量の氷塊を連続的に製造する自動製氷機が、喫茶店やレストラン等の施設その他の厨房において好適に使用されている。図８に例示する製氷機７０は、所謂噴射式の製氷機構２４を採用したものである。この製氷機構２４は、下向きに開口する製氷小室を多数画成した製氷部２６と、該製氷部２６の下方に位置して支軸２８ａにより傾動可能に支持された水皿２８と、この水皿２８の下部に一体的に設けられ、所定量の製氷水を貯留する製氷水タンク３０とを備えている。前記水皿２８は、製氷運転時には、水平に位置して製氷部２６を下方から閉成し、除氷運転時には、斜め下方に傾動して製氷部２６を開放する。この除氷運転では、製氷部２６から落下した氷塊Ｉが、傾斜姿勢にある水皿２８の上面を滑落して、製氷機構２４の下方に配設された貯氷室６８に放出貯留される。また、製氷水タンク３０内に残留した製氷残水(未氷結水)は、該製氷水タンク３０が傾斜姿勢になった際に、製氷機構２４の下方に配置された排水皿７２へ排出される。この排出された製氷残水は、排水皿７２の傾斜した内底面７４を流下して排水口７６に導かれ、排水パイプ６０を介して機外へ排出される。なお、製氷機構の下方に排水皿が配置された製氷機については、特許文献１に開示されている。   An automatic ice maker that continuously manufactures a large amount of ice blocks is suitably used in facilities such as coffee shops and restaurants and other kitchens. An ice making machine 70 illustrated in FIG. 8 employs a so-called injection type ice making mechanism 24. The ice making mechanism 24 includes an ice making portion 26 that defines a large number of ice making chambers that open downward, a water tray 28 that is positioned below the ice making portion 26 and is tiltably supported by a support shaft 28a, and the water tray. And an ice making water tank 30 that is integrally provided at a lower portion of 28 and stores a predetermined amount of ice making water. The water tray 28 is positioned horizontally during the ice making operation and closes the ice making unit 26 from below, and tilts downward and opens the ice making unit 26 during the deicing operation. In this deicing operation, the ice lump I that has fallen from the ice making unit 26 slides down on the upper surface of the water tray 28 in an inclined posture and is released and stored in an ice storage chamber 68 disposed below the ice making mechanism 24. Further, the ice making residual water (unfrozen water) remaining in the ice making water tank 30 is discharged to a drain tray 72 disposed below the ice making mechanism 24 when the ice making water tank 30 is inclined. . The discharged ice making residual water flows down the inclined inner bottom surface 74 of the drain pan 72, is guided to the drain port 76, and is discharged outside the machine through the drain pipe 60. Note that an ice making machine in which a drain tray is disposed below the ice making mechanism is disclosed in Patent Document 1.

図８に示すように、製氷機構２４と貯氷室６８との間に配置される前記排水皿７２は、製氷機構２４の製氷運転に伴う冷たい周囲温度や、製氷残水、更には貯氷室６８の冷たい空気との接触により冷却され、該排水皿７２の外底面７８には空気中の湿分が凝縮して結露を生ずることになる。なお、図８に示す製氷機７０は、製氷機構２４と冷凍機構(図示せず)とを備える製氷ユニット１２を、貯氷室６８を設けた貯氷庫６６に載置するスタックオンタイプを採用している。この場合、排水皿７２の外底面７８に生じた結露水Ｗが、図８に矢印で示すように排水皿７２の外底面７８を伝わって流れ、排水パイプ６０に達する。そして、排水パイプ６０を伝って製氷機７０のフレーム１４上に滴って溜まると、該フレーム１４と前記貯氷庫６６との載置面の僅かな隙間を表面張力により伝わり、機外へ流出しパネル面を濡らしてしまう欠点がある。   As shown in FIG. 8, the drainage tray 72 disposed between the ice making mechanism 24 and the ice storage chamber 68 has the cold ambient temperature, the ice making residual water, and further the ice storage chamber 68 in the ice making operation of the ice making mechanism 24. It cools by contact with cold air, and moisture in the air condenses on the outer bottom surface 78 of the drain pan 72 to cause dew condensation. 8 employs a stack-on type in which the ice making unit 12 including the ice making mechanism 24 and the refrigeration mechanism (not shown) is placed on the ice storage 66 provided with the ice storage chamber 68. Yes. In this case, the dew condensation water W generated on the outer bottom surface 78 of the drainage tray 72 flows along the outer bottom surface 78 of the drainage tray 72 as shown by an arrow in FIG. 8 and reaches the drainage pipe 60. Then, when it drops and accumulates on the frame 14 of the ice making machine 70 through the drain pipe 60, the slight gap between the mounting surfaces of the frame 14 and the ice storage 66 is transmitted by the surface tension, and flows out of the machine panel. There is a fault that wets the surface.

そこで本発明は、従来の技術に内在する前記問題に鑑み、これらを好適に解決するべく提案されたものであって、排水皿に生ずる結露水が機外へ漏出するのを防止することを目的とする。   Accordingly, the present invention has been proposed in order to suitably solve these problems inherent in the prior art, and an object of the present invention is to prevent the condensed water generated in the drain pan from leaking out of the apparatus.

In the following description, “front”, “rear”, “left”, “right”, “upper”, and “lower” are designated with reference to the ice making machine viewed from the front side shown in FIG. To do. In addition, about the member same as a prior art, it shows with the same code | symbol.

図６に示すように、実施例に係る排水皿３６が配設される製氷機１０は、貯氷室６８を設けた貯氷庫６６の上部に、製氷機構２４および冷凍機構２０を備える製氷ユニット１２を載置するスタックオンタイプのものである。製氷ユニット１２は、外骨格をなす矩形状の立体フレーム１４の前後、左右および上面の夫々に、矩形状のパネル１６を組み付けた筺体を本体としている。この筺体の内部上方には、圧縮機ＣＭ、凝縮器ＣＤ等の冷凍機構２０や電装箱ＣＢを収納した機械室１８が配置され、また内部下方には、製氷機構２４を収納した製氷室２２が配置されている。前記貯氷庫６６は、内箱と外箱との間に断熱材を充填した断熱箱体からなり、上方に開放して前記製氷室２２と空間的に連通する貯氷室６８を備え、製氷機構２４から落下する氷塊Ｉを該貯氷室６８で受けて貯留するようになっている。   As shown in FIG. 6, the ice making machine 10 in which the drain tray 36 according to the embodiment is disposed includes the ice making unit 12 including the ice making mechanism 24 and the refrigeration mechanism 20 on the ice storage 66 provided with the ice storage chamber 68. It is a stack-on type. The ice making unit 12 has as its main body a housing in which rectangular panels 16 are assembled on the front, rear, left and right and top surfaces of a rectangular solid frame 14 forming an exoskeleton. A machine room 18 containing a refrigeration mechanism 20 such as a compressor CM and a condenser CD and an electrical box CB is disposed above the housing, and an ice making room 22 containing an ice making mechanism 24 is located below the inside. Has been placed. The ice storage 66 is formed of a heat insulating box filled with a heat insulating material between an inner box and an outer box, and includes an ice storage chamber 68 that opens upward and communicates spatially with the ice making chamber 22. The ice lump I falling from the ice is received by the ice storage chamber 68 and stored.

前記製氷機構２４は、図６に示すように、製氷室２２の内部上方に配設されている。この製氷機構２４は、下向きに開口する製氷小室を多数画成した製氷部２６と、前記冷凍機構２０に接続して前記製氷部２６の上面に蛇行配置した蒸発器ＥＰと、前記製氷部２６の下方に配設された水皿２８と、この水皿２８の下部に一体的に設けられた製氷水タンク３０とを備えている。前記水皿２８は、左側端部が支軸２８ａによって斜め下方へ傾動可能に支持され、右側端部が水皿開閉機構ＡＭに接続されている。そして水皿２８は、水皿開閉機構ＡＭの正逆駆動により、前記製氷部２６を下方から塞ぐ閉成姿勢と、製氷水タンク３０と一体的に傾動して製氷部２６を開放する開放姿勢とに姿勢変位する。製氷運転では、蒸発器ＥＰにより製氷部２６を冷却したもとで、閉成姿勢にある水皿２８から製氷部２６の製氷小室に製氷水を供給することで各製氷小室に氷塊Ｉが製造される。また、除氷運転では、冷凍機構２０から蒸発器ＥＰにホットガスを供給して、製氷小室と氷塊Ｉとの氷結面を融解する。この除氷運転では、水皿２８が開放姿勢に変位するので、氷塊Ｉは製氷部２６から重力により落下し、水皿２８の傾斜面上を滑落して前記貯氷室６８に放出貯留される。また、除氷運転に伴い傾動開放した製氷水タンク３０から放出される製氷残水は、後述する排水皿３６に排出される。   The ice making mechanism 24 is disposed in the upper part of the ice making chamber 22 as shown in FIG. The ice making mechanism 24 includes an ice making unit 26 that defines a large number of ice making chambers that open downward, an evaporator EP that is connected to the refrigeration mechanism 20 and meanders on the upper surface of the ice making unit 26, and the ice making unit 26 A water tray 28 disposed below is provided, and an ice making water tank 30 provided integrally with the lower portion of the water tray 28. The water tray 28 is supported by a support shaft 28a so that the left end thereof can tilt obliquely downward, and the right end is connected to a water tray opening / closing mechanism AM. The water tray 28 has a closed posture in which the ice making unit 26 is closed from below by forward and reverse driving of the water tray opening / closing mechanism AM, and an open posture in which the ice making unit 26 is tilted integrally with the ice making water tank 30 to open. The posture is displaced. In the ice making operation, ice pieces I are produced in each ice making chamber by supplying ice making water from the water tray 28 in the closed position to the ice making chamber of the ice making portion 26 while the ice making portion 26 is cooled by the evaporator EP. The In the deicing operation, hot gas is supplied from the refrigeration mechanism 20 to the evaporator EP to melt the icing surface between the ice making chamber and the ice block I. In this deicing operation, since the water tray 28 is displaced to the open posture, the ice lump I falls by gravity from the ice making unit 26, slides on the inclined surface of the water tray 28, and is released and stored in the ice storage chamber 68. Further, the remaining ice making water discharged from the ice making water tank 30 that is tilted and released in accordance with the deicing operation is discharged to a drain tray 36 described later.

図６に示すように、製氷室２２の内部下方における右側に偏った位置には、除氷運転で水皿２８上面を滑落した氷塊Ｉを貯氷室６８へ案内するアイスシュート３２が設けられている。このアイスシュート３２は、上下および左側に開放する平面コ字状に形成されている。製氷室２２におけるアイスシュート３２の左側には、後述する排水皿３６が設置され、除氷運転で水皿２８の上面を滑落した氷塊Ｉは、この排水皿３６とアイスシュート３２との間に形成された氷放出経路３４を通って貯氷室６８に放出される。   As shown in FIG. 6, an ice chute 32 that guides the ice lump I that has slid down the upper surface of the water dish 28 by the deicing operation to the ice storage chamber 68 is provided at a position biased to the right in the lower part of the ice making chamber 22. . The ice chute 32 is formed in a planar U-shape that opens up and down and to the left. On the left side of the ice chute 32 in the ice making chamber 22, a drain tray 36 to be described later is installed, and the ice lump I sliding down the upper surface of the water tray 28 by deicing operation is formed between the drain tray 36 and the ice chute 32. The ice is discharged into the ice storage chamber 68 through the ice discharge path 34.

図６に示すように、製氷水タンク３０の下方における前記アイスシュート３２の左側には、除氷運転に際し、製氷水タンク３０の傾動に伴い排出される製氷残水を受入れて、該製氷残水を排水口３８から機外へ排出する排水皿３６が設けられている。この排水皿３６は、例えば図１に示すように、略矩形の底板部４０と、この底板部４０の前後および左右の端縁に所要高さで夫々立設された前壁部４２ａ、後壁部４２ｂ、左壁部４２ｃおよび右壁部４２ｄとから、上方に開放するトレー状に形成されている。また、前記底板部４０の左奥側に偏った位置には、排水口３８が形成されている。実施例の排水皿３６は、例えば合成樹脂を材質とする成形品であって、ブロー成形や回転成形により中空体に形成される。   As shown in FIG. 6, on the left side of the ice chute 32 below the ice making water tank 30, the ice making residual water discharged along with the tilting of the ice making water tank 30 during the deicing operation is received. A drainage tray 36 is provided for discharging the wastewater from the drainage port 38 to the outside of the apparatus. For example, as shown in FIG. 1, the drain tray 36 includes a substantially rectangular bottom plate portion 40, a front wall portion 42 a erected on the front and rear and left and right edges of the bottom plate portion 40 at a required height, and a rear wall. From the part 42b, the left wall part 42c, and the right wall part 42d, it is formed in a tray shape that opens upward. Further, a drain port 38 is formed at a position biased to the left rear side of the bottom plate portion 40. The drainage tray 36 of the embodiment is a molded product made of, for example, a synthetic resin, and is formed into a hollow body by blow molding or rotational molding.

前記底板部４０は、図３および図４に示すように、内底面４６と外底面５０との間に中空部４４が形成され、該内底面４６および外底面５０が中空部４４を介して上下に対向して配置されている。前記製氷水タンク３０からの製氷残水を受止める内底面４６は、全体として排水口３８へ向けて下方傾斜するよう形成され、内底面４６で受け止めた排水が、該内底面４６上を流下して円滑に排水口３８へ導かれるようになっている。また図１に示すように、内底面４６には、上方に突出する案内部４８が所定の長さで複数(実施例では２つ)設けられ、製氷水タンク３０からの排水が跳ね上がったり外部へ飛散したりするのを防止する。   As shown in FIGS. 3 and 4, the bottom plate portion 40 has a hollow portion 44 formed between an inner bottom surface 46 and an outer bottom surface 50, and the inner bottom surface 46 and the outer bottom surface 50 are vertically moved via the hollow portion 44. It is arranged to face. The inner bottom surface 46 for receiving the ice making residual water from the ice making water tank 30 is formed so as to incline downward toward the drain port 38 as a whole, and the drainage received at the inner bottom surface 46 flows down on the inner bottom surface 46. Thus, the water is smoothly guided to the drain port 38. Further, as shown in FIG. 1, the inner bottom surface 46 is provided with a plurality of guide portions 48 (two in the embodiment) protruding upward with a predetermined length, and the drainage from the ice making water tank 30 jumps up or out. Prevents scattering.

図３および図４に示すように、底板部４０における前記貯氷室６８に臨む外底面５０は、全体として略水平方向に延在するよう形成されている。この外底面５０には、結露水Ｗ(図７参照)を滴下させる水切り用の垂下壁５２が形成されている。垂下壁５２は、図２に示すように、外底面５０の外周に沿って外底面５０の周縁部に延設されている。すなわち、垂下壁５２によって外底面５０の大部分が取り囲まれるようになっている。外底面５０の周縁部における排水口３８が開設された部位では、該排水口３８を避けて外底面５０における排水口３８より内側に垂下壁５２が形成されている。すなわち、排水口３８は外底面５０における垂下壁５２の外側に形成されている。図３〜図５に示すように、垂下壁５２は、外底面５０における外側に位置する傾斜面５２ａと、外底面５０における内側に位置する垂直面５２ｂとから断面略Ｖ字状となるよう下方へ突出形成されている。前記傾斜面５２ａは、外底面５０の内側へ向かって下方傾斜している。また、外底面５０には、図２〜図４に示すように、前後方向に延在する補強リブ５４が前記垂下壁５２の内側に複数(実施例では３つ)形成され、排水皿３６を補強して反りや変形を防止している。なお、垂下壁５２、補強リブ５４等の外底面５０の形状は、中空構造であるから内底面４６に表れることはない。   As shown in FIGS. 3 and 4, the outer bottom surface 50 facing the ice storage chamber 68 in the bottom plate portion 40 is formed so as to extend in a substantially horizontal direction as a whole. The outer bottom surface 50 is formed with a hanging wall 52 for draining the condensed water W (see FIG. 7). As shown in FIG. 2, the hanging wall 52 extends along the outer periphery of the outer bottom surface 50 to the peripheral edge of the outer bottom surface 50. That is, most of the outer bottom surface 50 is surrounded by the hanging wall 52. At a portion where the drainage port 38 is opened at the peripheral edge of the outer bottom surface 50, a hanging wall 52 is formed inside the drainage port 38 on the outer bottom surface 50, avoiding the drainage port 38. That is, the drain port 38 is formed outside the hanging wall 52 in the outer bottom surface 50. As shown in FIGS. 3 to 5, the drooping wall 52 has a substantially V-shaped cross section from an inclined surface 52 a located outside the outer bottom surface 50 and a vertical surface 52 b located inside the outer bottom surface 50. It is formed to protrude. The inclined surface 52 a is inclined downward toward the inside of the outer bottom surface 50. Further, as shown in FIGS. 2 to 4, a plurality of (three in the embodiment) reinforcing ribs 54 extending in the front-rear direction are formed on the outer bottom surface 50 inside the hanging wall 52. Reinforces to prevent warping and deformation. Note that the shape of the outer bottom surface 50 such as the hanging wall 52 and the reinforcing rib 54 does not appear on the inner bottom surface 46 because of the hollow structure.

図１および図２に示すように、排水皿３６の右壁部４２ｄには、壁部の高さの低い放出口５６が形成され、該放出口５６が設けられた右壁部４２ｄの外面には、上端から下端に亘って放出流路５８が凹設されている。これにより、排水口３８が詰まる等の理由により容量を超えて排水皿３６へ排出された製氷残水は、前記放出口５６から放出され、放出流路５８を通って排水皿３６の下方に位置する貯氷室６８へオーバーフローする。排水皿３６の右壁部４２ｄは、前記氷放出経路３４に臨んでいるため、放出流路５８を流下する排水が表面張力によりパネル１６を伝って機外へ漏出することはない。なお、貯氷室６８へ流下した排水は、該貯氷室６８の底部に形成された図示しない排水口を介して機外へ排出される。また、図２に示すように、外底面５０の周縁部における前記放出流路５８に対応する部位には、前記垂下壁５２が形成されておらず、少量の排水であれば放出流路５８から表面張力により外底面５０へ案内されるようになっている。なお、外底面５０へ案内された排水は、後述する外底面５０に生じる結露水Ｗと同様に、貯氷室６８へ滴下されるようになっている。   As shown in FIGS. 1 and 2, the right wall portion 42d of the drainage tray 36 is formed with a discharge port 56 having a low wall portion, and on the outer surface of the right wall portion 42d provided with the discharge port 56. The discharge channel 58 is recessed from the upper end to the lower end. Thereby, the ice making residual water discharged to the drainage tray 36 exceeding the capacity due to the drainage port 38 being clogged or the like is discharged from the discharge port 56 and is positioned below the drainage tray 36 through the discharge channel 58. Overflow to the ice storage chamber 68. Since the right wall portion 42d of the drainage tray 36 faces the ice discharge path 34, the drainage flowing down the discharge passage 58 does not leak out of the machine through the panel 16 due to surface tension. The waste water flowing down to the ice storage chamber 68 is discharged out of the apparatus through a drain port (not shown) formed at the bottom of the ice storage chamber 68. In addition, as shown in FIG. 2, the hanging wall 52 is not formed in a portion corresponding to the discharge channel 58 in the peripheral portion of the outer bottom surface 50, and a small amount of drainage is used from the discharge channel 58. It is guided to the outer bottom surface 50 by surface tension. The drainage guided to the outer bottom surface 50 is dripped into the ice storage chamber 68 in the same manner as the dew condensation water W generated on the outer bottom surface 50 described later.

図７に示すように排水皿３６は、外底面５０における前記垂下壁５２の形成部位よりも外側で、筺体を構成する前記フレーム１４により当接支持されている。そして前記排水口３８には、図６および図７に示すように、Ｌ字状の排水パイプ６０がパッキン６２を挟んだキャップ６４で接続されている。排水パイプ６０は、パネル１６に開設された開口部１６ａを介して機外に延出され、図示しない排水ホース等に接続されている。   As shown in FIG. 7, the drainage tray 36 is abutted and supported by the frame 14 that forms the housing on the outer bottom surface 50 outside the site where the hanging wall 52 is formed. As shown in FIGS. 6 and 7, an L-shaped drain pipe 60 is connected to the drain port 38 with a cap 64 with a packing 62 interposed therebetween. The drainage pipe 60 extends outside the machine through an opening 16a opened in the panel 16, and is connected to a drainage hose (not shown).

次に、実施例に係る排水皿３６の作用および効果を、図７を参照して、結露水Ｗの流れを中心に説明する。排水皿３６は、製氷機構２４の製氷運転による製氷室２２の冷却雰囲気や、製氷水タンク３０からの製氷残水によって冷却される。このため、下方に臨む貯氷室６８の空気が接触する外底面５０には、空気中の湿分が冷却されて結露水Ｗを生じる。実施例に係る排水皿３６では、外底面５０に結露水Ｗが生じたとしても、該外底面５０の外周に沿って延設された垂下壁５２によって、該結露水Ｗを貯氷庫６６へ滴下できる。従って、外底面５０に生じた結露水Ｗが、仮に外底面５０に沿って周縁部に向かって流れたとしても、垂下壁５２よりも外側へ流れるのは阻止される。このため、結露水Ｗがパネル１６やフレーム１４にまで達することはなく、該結露水Ｗが機外へ漏出することはない。また、排水皿３６は、排水口３８が底板部４０における外側に片寄って形成されると共に、垂下壁５２が外底面５０における該排水口３８の内側に形成されている。このため、外底面５０に生じた結露水Ｗが排水パイプ６０に向かって流れたとしても、該結露水Ｗは排水パイプ６０の手前で垂下壁５２によって貯氷室６８へ案内される。従って、外底面５０に生じた結露水Ｗが排水パイプ６０に達しないので、該結露水Ｗが排水パイプ６０を伝ってフレーム１４上に落下し、表面張力によりパネル１６を介して機外へ漏出することはない。なお、貯氷室６８へ落下した結露水Ｗは、該貯氷室６８の底部に形成された図示しない排水口を介して機外へ排出される。   Next, the operation and effect of the drainage tray 36 according to the embodiment will be described with reference to FIG. 7 focusing on the flow of the condensed water W. The drain tray 36 is cooled by the cooling atmosphere of the ice making chamber 22 by the ice making operation of the ice making mechanism 24 or the ice making residual water from the ice making water tank 30. For this reason, the moisture in the air is cooled on the outer bottom surface 50 with which the air in the ice storage chamber 68 facing downwards comes into contact, and condensed water W is generated. In the drain tray 36 according to the embodiment, even if the dew condensation water W is generated on the outer bottom surface 50, the dew condensation water W is dropped onto the ice storage 66 by the hanging wall 52 extending along the outer periphery of the outer bottom surface 50. it can. Therefore, even if the dew condensation water W generated on the outer bottom surface 50 flows toward the peripheral edge along the outer bottom surface 50, it is prevented from flowing outside the hanging wall 52. For this reason, the dew condensation water W does not reach the panel 16 or the frame 14, and the dew condensation water W does not leak out of the apparatus. Further, the drainage tray 36 is formed such that the drainage port 38 is offset toward the outside of the bottom plate portion 40, and the hanging wall 52 is formed inside the drainage port 38 on the outer bottom surface 50. For this reason, even if the condensed water W generated on the outer bottom surface 50 flows toward the drain pipe 60, the condensed water W is guided to the ice storage room 68 by the hanging wall 52 before the drain pipe 60. Accordingly, since the condensed water W generated on the outer bottom surface 50 does not reach the drain pipe 60, the condensed water W falls on the frame 14 through the drain pipe 60, and leaks out of the machine via the panel 16 due to surface tension. Never do. The condensed water W that has fallen into the ice storage chamber 68 is discharged out of the machine through a drain port (not shown) formed at the bottom of the ice storage chamber 68.

実施例の排水皿３６は、内底面４６と外底面５０との間に中空部４４が形成され断熱空間を有しているので、内底面４６に受入れた製氷水タンク３０からの製氷残水によって外底面５０が冷やされる程度は大きくない。このため、貯氷室６８の空気が排水皿３６の外底面５０で冷やされることで生じる結露水Ｗを大幅に減少させることができる。また、垂下壁５２を形成した外底面５０と、排水を排水口３８へ案内する内底面４６とを中空部４４を介した二重構造としたので、外底面５０に垂下壁５２を形成しても、内底面４６の形状に影響を与えることはなく、内底面４６における円滑な排水を損なわない。実施例のように外底面５０に垂下壁５２を有する排水皿３６を、真空成形により中実に形成した場合、垂下壁５２の影響で内底面４６に凹みが生じ、この凹みに排水が溜まり不衛生になる虞がある。実施例の排水皿３６は、ブロー成形や回転成形により中空体に形成するので、外底面５０にのみ垂下壁５２を容易に形成できる。   Since the drainage tray 36 of the embodiment has a heat insulating space with the hollow portion 44 formed between the inner bottom surface 46 and the outer bottom surface 50, the ice making residual water from the ice making water tank 30 received in the inner bottom surface 46 is used. The degree to which the outer bottom surface 50 is cooled is not large. For this reason, the dew condensation water W generated when the air in the ice storage chamber 68 is cooled by the outer bottom surface 50 of the drain tray 36 can be significantly reduced. Further, since the outer bottom surface 50 in which the hanging wall 52 is formed and the inner bottom surface 46 for guiding the drainage to the drain port 38 have a double structure through the hollow portion 44, the hanging wall 52 is formed on the outer bottom surface 50. However, the shape of the inner bottom surface 46 is not affected, and smooth drainage at the inner bottom surface 46 is not impaired. When the drainage tray 36 having the hanging wall 52 on the outer bottom surface 50 is solidly formed by vacuum forming as in the embodiment, a recess is generated in the inner bottom surface 46 due to the influence of the hanging wall 52, and drainage accumulates in this recess, which is unsanitary. There is a risk of becoming. Since the drain tray 36 of the embodiment is formed into a hollow body by blow molding or rotational molding, the hanging wall 52 can be easily formed only on the outer bottom surface 50.
