【0010】
【発明の実施の形態】
以下、本発明の一実施形態を図面に基づいて説明する。
【0011】
図1において、1はいわゆる逆セル型の製氷装置を示している。この製氷装置1は、断熱構造の本体(図示せず)内に形成された製氷室(図示せず)の上部に掛け渡された支持梁2によって支持されている。断熱構造の本体(図示せず)内には製氷装置1によって製氷された氷を貯氷する貯氷室(図示せず)が製氷室(図示せず)とは別に設けられている。
【0012】
製氷装置1は、下面に下向きに開口した複数の製氷室4Aを有し、上面に蛇行する冷却管からなる冷却器4Bを有する製氷部4と、この製氷部4に設けられ、冷却器4Bの温度を検知する冷却器温度センサ20と、一側を回動可能に支持され、各製氷室4Aを下方から閉塞する水皿5と、この水皿5に固定された水タンク6と、この水タンク6内に給水された製氷水を水皿5の表面に形成された噴水口(図示せず)から各製氷室4Aに噴射する循環ポンプ7と、回動可能に支持された水皿5を傾動、復動させるための正逆回転可能な水皿開閉用モータ8を含む駆動機構9とで構成されている。
【0013】
水皿開閉用モータ8の回転軸にはアーム12が固定され、このアーム12の一端側12Aにはコイルばね13の一端が取り付けられ、このコイルばね13の他端が水皿5の側部に連結されている。
【0014】
なお、このアーム12とコイルばね13とは対になって、水皿5の左右に設けられている。水皿開閉用モータ8は正転で水皿5を開くと共に、逆転で水皿5を閉じるように構成されている。
【0015】
21は散水器であり、この散水器21は、後述する離氷工程で水皿5が開く場合に(図2)、水皿5の表面に散水する。
【0016】
つぎに、本製氷装置の動作について図5及び図6を参照して説明する。尚、説明の便宜上、フローチャート中に(1)(2)(3)…(11)(12)(13)と番号表示し、以下この各動作に対応してフローを説明する。
【0017】
(1)電源を投入すると、コンプレッサ、給水バルブ、ポンプモータがONし(S21)、水皿5が満水になった場合には(S22)、給水工程を終了し洗浄工程に移る。この動作は最初の製氷サイクルに先立って1回だけ製氷装置1の洗浄を行うための給水である。
【0018】
(2)初回洗浄工程ではコンプレッサ、ポンプモータ、ファンモータがON(S23)、給水バルブ、ホットガスバルブがOFFで(S24)、所定の時間(例えば30秒)洗浄を行い(S25)、判断S25が、YESで洗浄を終えたら離氷(洗浄水排水)工程に移る。
【0019】
(3)本離氷工程は洗浄水を排水する為のもので、水皿5を開け排水したらすぐに水皿5を閉じ、本来の製氷工程に入るための給水工程に入る。尚、この離氷工程は製氷工程の次に続く本来の離氷工程と同じ動作であり、コンプレッサ、ホットガスバルブ、給水バルブをON(S26)、ポンプモータ、ファンモータをOFF(S27)とした後、水皿5を開き、開いたら給水バルブをOFFとし(S28)、製氷部4の温度を冷却器温度センサ20(フローチャート内ではETとする。)にて検出し、その温度が離氷完了検知温度に到達しているか否かを判断し(S29)、この判断の結果、水皿5を閉じる(S30)。
【0020】
(4)コンプレッサ、給水バルブ、ポンプモータがON(S31)、ファンモータ、ホットガスバルブがOFFで(S32)、満水になるまで給水を続け(S33)、満水になったら(S33)製氷工程に移る。
【0021】
(5)製氷工程では、コンプレッサ、ポンプモータ、ファンモータをON(S34)、給水バルブ、ホットガスバルブをそれぞれOFFにして(S35)、製氷運転を行う。製氷を行う場合には、図1に示すように、水皿5が閉じ、循環ポンプ7が駆動され、図示を省略した噴水口を通じて、水タンク6内の製氷用水が各製氷室4Aに噴射され、この製氷用水が冷却器4Bによって製氷される。
【0022】
(6)製氷サイクルに入ると製氷部4を所定温度になるまで冷却する予冷工程を行う。即ち、冷却器温度センサ20で製氷部4の温度を検出し、所定温度(例えば0℃)に達したか否かを判断する(S36)。S36で所定温度に到達したら製氷タイマをスタートさせる(S37)。
【0023】
(7)製氷タイマをスタートさせ、残り製氷タイマ時間が経過するまで製氷を続け、製氷タイマがカウントアップしたら、離氷行程に移行する(S38)。
【0024】
(8)離氷行程に移行すると、コンプレッサ、給水バルブ、ホットガスバルブをON(S39)、ポンプモータ、ファンモータをそれぞれOFFとして(S40)、水皿5を開く、この場合には、まず、水皿開閉用モータ8が正転される。水皿5が開き切る時には、図2に示すように、アーム12が反時計方向に回転し、このアーム12の他端側12Bが、モータ停止用制御スイッチ14を動作し、水皿開閉用モータ8への通電を停止すると共に、つぎの復動を可能にさせるために、モータ駆動回路(図示せず)を逆転可能な状態に切り替える。このモータ停止用制御スイッチ14は支持梁2に固定されている。
【0025】
(9)水皿5が開いたら給水バルブをOFFにする(S41)。
【0026】
(10)冷却器が氷の落下する温度となるのを待ち、即ち冷却器温度センサ20が離氷完了検知温度に到達するのを待ち(S42)、離氷完了検知温度に到達したら水皿5を閉める(S43)。
【0027】
(11)貯氷部に貯氷センサ(図示せず)が設けられ、この貯氷センサにより満氷の検知が行われている。
【0028】
(12)貯氷庫内が満氷であると(S44)、水皿5を開き(S45)、コンプレッサ、給水バルブ、ホットガスバルブ、ポンプモータ、ファンモータをOFFにして停止する(S46)。
【0029】
(13)運転が一時停止し、氷が取り出されることで満氷でなくなったら(S47)、水皿5を閉じて(S48)、再び(4)の製氷行程に移行する。
【0030】
つぎに、逆セル型製氷機の水皿5、及び水タンク6の構造を説明する。
【0031】
この水皿5には、図3に示すように、周壁部19が一体的に形成され、この周壁部19の外周面には、製氷水を貯留するための前述した水タンク6が下方から嵌合されている。この水皿5には、製氷水通路32が一体的に形成され、この製氷水通路32を通じて供給される製氷水が、噴出孔33から製氷室4Aに噴出され、製氷室4Aで製氷されるように構成されている。
【0032】
そして、余剰となった製氷水は、水皿5に形成された戻り孔35を通じて水タンク6内に戻されるように構成されている。
【0033】
この実施形態では、水皿5の周壁部19の内壁面に沿って落下する水が、水皿5と水タンク6との接合部38から外部に流出しないように、当該水を水タンク6内に案内する水切り板37が設けられている。
【0034】
より詳細に説明すると、この水皿5には、図4aに示すように、製氷水流入口39につながる縦に延びるヘッダー(製氷水通路壁)34と、このヘッダー34につながる複数の横に延びる製氷水通路32とが一体的に形成されている。
【0035】
ヘッダー34は、図4bに示すように、製氷水通路33aを有し、このヘッダー34の外壁には、断面逆L字状の水切り板37が形成されている。この水切り板37は、図4cに示すように、先端37aが鋭角に切り落とされ、外壁面には、水垂れ案内面37bが形成されている。また、水皿5の周壁部19の内壁面には、図4dに示すように、前記と同様の構成の水切り板37が形成されている。
【0036】
この構成では、余剰となった製氷水が、水皿5に形成された戻り孔35を通じて水タンク6内に戻される場合、水皿5の周壁部19の内壁面に沿って流れる水が、水切り板37の水垂れ案内面37bに沿って水タンク6内に案内されるので、水タンク6と水皿5との接合部38に接触することがなく、毛細管現象によって接合部38から水が外部に漏洩することがない。
【0037】
また、水切り板37の先端37aが鋭角に加工されている場合には、この先端37aで、水垂れの効果がさらに増進される。
【0038】
この水切り板37は水皿5の略全周に設けられており、これによれば、製氷水が、水タンク6外へ漏洩することがない。
【0039】
以上、一実施形態に基づいて本発明を説明したが、本発明はこれに限定されるものではないことは明らかである。例えば、水切り板37は水皿5の全周に亘って設けず、一部に設けるようにしてもよい。
【0040】
【発明の効果】
これらの発明では、水切り板を形成したことで、水皿の周壁部の内壁面に沿って落下する水が、水タンク内に案内されるので、当該水が、水皿と水タンクとの接合部から外部に流出することがない。

Since the water is guided into the water tank 6 along the water dripping guide surface 37b of the plate 37, the water does not come into contact with the joint 38 between the water tank 6 and the water dish 5, and water is externally supplied from the joint 38 by capillary action. Will not leak.
[0037]
Further, when the tip 37a of the draining plate 37 is machined at an acute angle, the effect of dripping is further enhanced at the tip 37a.
[0038]
The draining plate 37 is provided on substantially the entire circumference of the water dish 5, and according to this, the ice making water does not leak out of the water tank 6.
[0039]
As mentioned above, although this invention was demonstrated based on one Embodiment, it is clear that this invention is not limited to this. For example, the draining plate 37 may not be provided over the entire circumference of the water dish 5 but may be provided in part.
[0040]
【The invention's effect】
In these inventions, since the draining plate is formed, the water falling along the inner wall surface of the peripheral wall portion of the water dish is guided into the water tank, so that the water is joined to the water dish and the water tank. There is no outflow from the department.
