Description

【０００１】
【発明の属する技術分野】
本発明は製氷機に関し、より詳しくは電源印加時に製氷機の誤動作を防止し、迅速に製氷を再開始できる製氷機の初期動作制御方法に関する。
【０００２】
【従来の技術】
一般に、製氷機は給水された製氷水を冷却させて氷を作る装置であり、図１には従来の製氷機が示されている（特許文献１参照）。
【０００３】
同図に示したように、従来の製氷機は、製氷機本体１０及び製氷部２０を含む。製氷機本体１０の内部には製氷部２０で作られた氷を貯蔵するための貯氷庫１１が配設され、貯氷庫１１の下部には圧縮機３１と凝縮機３２とを有する冷凍システム３０が配設される。さらに、製氷機本体１０には製氷水を、蒸発機２３を有する製氷部２０へ供給するための給水管１２及び、製氷部２０で結氷されていない製氷水を製氷機本体１０の外部へ排出させるための排水管１３が連結される。給水管１２は未図示の水設備から製氷部２０まで延設され、排水管１３は貯氷庫１１に設置された集水部１４から未図示の排水設備まで延設される。

【０００５】
【発明が解決しようとする課題】
しかし、前述のように構成された製氷機の使用途中に、停電やユーザの電源遮断などによって製氷機の稼動中止が発生することがある。この場合は、製氷部２０に生成中の氷が残存することがあり得るが、このとき、電源が印加されて製氷機が氷の有無または製氷槽２７の位置などへの考慮なしに製氷を直ちに開始すると、正常的な氷形成が不能となり、製氷機へ機械的な衝撃が発生する恐れがある。
【０００６】
すなわち、製氷部２０に生成中の氷が残った状態で、製氷初期モードで製氷が始まる場合、給水管１２を介して製氷水が新しく供給される。ところが、製氷動作中に製氷機が停止したら、製氷槽２７の内部には製氷水が残っているため、製氷槽は製氷水を全部収容できず、排水口へ捨てられる製氷水が発生することになる。
【０００７】
また、製氷部２０に生成中の氷が残存する場合、製氷が再開始されると、生成中にある氷の上に氷が更に生成されるため、氷の品質が低下し、これにより透明な氷が得られないだけでなく、製氷槽２７の揺動時に生成中の氷が製氷槽２７を打撃して、機械的な衝撃を発生させてしまうという問題点があった。
【０００８】
本発明は上記のような問題点に鑑みてなされたもので、その目的は製氷機に電源が印加される場合、制御ユニットにより製氷槽の位置を検知して製氷ユニットに残留した製氷水及び氷を取り除くことができる製氷機の初期動作制御方法を提供することにある。
【０００９】
【課題を解決するための手段】
前記目的を達成するために、本発明による製氷槽の位置検知センサを用いた製氷機の初期動作制御方法は、閉鎖検知センサにより製氷槽の開閉有無を検知する段階と；製氷槽が閉じているときに回転させ、開けているときにその状態を維持させる段階；製氷部の氷を分離する段階と；製氷槽に製氷水を給水して製氷を行う段階と；製氷済みの氷を投出して貯蔵する段階と；を含むことを特徴とする。
【００１０】
本発明の好適な実施の形態によれば、前記製氷槽が閉じているときに回転させる段階は、所定の制御ユニットにより前記製氷槽が開放され、製氷部が貯氷庫に露出されるように、製氷槽回転ユニットを駆動させる段階と；開放検知センサは、製氷槽が所定の開放位置に位置したことを検知する段階と；前記開放検知センサの位置検知信号により前記制御ユニットが製氷槽回転ユニットを停止させる段階と；を含むことが望ましい。
【００１１】
また、前記製氷部の氷を分離する段階は、凝縮していない高温高圧の冷媒を蒸発機へ循環させて前記製氷部に氷結された氷を分離する段階を含むことが好ましい。
【００１２】
【発明の実施の形態】
以下、添付図面に基づき本発明の望ましい実施の形態を説明する。ここで、従来の構成及び作用と同じ部材には同一の符号を付ける。
【００１３】
図２は本発明による製氷機の製氷ユニットを示した図であり、１１０は製氷ユニット本体、１２０は製氷槽組立体、１３０は閉鎖検知センサ、１４０は開放検知センサである。製氷ユニット１１０の下部には、製氷ユニット１１０が氷を生成できるように製氷水を供給し、製氷が完了したとき、製氷ユニット１１０が貯氷庫１１に露出できるように開放される製氷槽組立体１２０が回転自在に設けられる。
【００１４】
製氷槽組立体１２０は、貯氷庫１１の上部からほぼ９０度の角度で下方への回転及び復帰可能にするよう製氷ユニット１１０に回動自在に設置される。かかる製氷槽組立体１２０は板状の製氷槽支持プレート１２２と、製氷槽支持プレート１２２の一側に設けられる一対の軸支持部１２２ａを有する。軸支持部１２２ａのそれぞれには、支持軸（図示せず）が設けられ、いずれかの軸支持部１２２ａには回転駆動モータ（図示せず）の動力によって回転される旋回軸１２４が連結される。前記支持軸は製氷ユニット１１０の下部に設けられた支持部１２２ｂに回動自在に連結される。
【００１５】
製氷槽１２１は製氷槽組立体１２０の上部に昇降可能に設置される。このために、製氷槽１２１と製氷槽支持プレート１２２との間には、バネ１２３が設置される。製氷槽１２１の上面には、製氷水が充填される複数の凹溝部が形成される。また、製氷槽１２１の上面一側には製氷がなされず、残留水を排水させるための排水路が形成される。製氷槽支持プレート１２２が９０度の角度で下方へ回転されたとき、前記排水路を介して水が排出される。この排水される水を受けるための樋（図示せず）が貯氷庫１１内に設置される。製氷槽１２１は所定の案内部材によって昇降ガイドされ、製氷槽支持プレート１２２と一緒に回動される。
【００１６】
製氷ユニット本体１１０は、複数の冷却突起を有する製氷部２０と透明氷の生成のために製氷槽組立体１２０を上下に揺動させるカム装置を駆動するカムモータ１１１が設置される。
【００１７】
製氷槽組立体１２０は、製氷部２０に設けられた冷却突起に製氷水を供給するもので、製氷が完了したとき、図２に示したように回転して前記冷却突起を開放する。このように冷却突起が開放されると、所定の氷分離手段により冷却突起に形成された氷が分離され、この分離された氷は貯氷庫１１に貯蔵される。
【００１８】
また製氷槽組立体１２０は、製氷水を収容する製氷槽１２１と、製氷槽１２１を支持する製氷槽支持プレート１２２とからなる。製氷槽１２１は、製氷槽支持プレート１２２にバネ１２３によって支持され、カムモータ１１１によって駆動されるカム装置によって上下方向に揺動される。
【００１９】
そして、製氷槽支持プレート１２２は、その一端に所定の駆動ユニットに連結される旋回軸１２４を含む。旋回軸１２４によって、製氷槽１２１を有する製氷槽組立体１２０が回動され、これによって前記冷却突起は貯氷庫１１に向かって露出する。
【００２０】
一方、製氷ユニット１１０の外郭を構成する製氷ユニットフレーム１１２には、閉鎖検知センサ１３０が設置される。この閉鎖検知センサ１３０は、製氷ユニットフレーム１１２の終端に、閉鎖検知センサ１３０の検知部が製氷槽組立体１２０に向かって設置される。望ましくは、製氷槽支持プレート１２２の閉鎖検知センサ１３０の配設位置に対応する部分に埋設されたマグネットを閉鎖検知センサ１３０が検知して製氷槽組立体１２０が閉じているかどうかを判断する。
【００２１】
なお、開放検知センサ１４０は、製氷ユニットフレーム１１２に設置され、製氷槽支持プレート１２２が最大開放位置に到達するときに検知信号が出力されるように、製氷槽支持プレート１２２の旋回軸１２４の軸線のほぼ中央の近傍に設置されることが望ましい。また、製氷槽支持プレート１２２の開放検知センサ１４０の対応箇所にはマグネットが埋設されている。したがって、所定の制御ユニットは、開放検知センサ１４０に前記マグネットが近づく場合を、製氷槽支持プレート１２２の開放状態として認識する。
【００２２】
次に、本発明による製氷機の初期動作制御方法を、図３に示した製氷機の概略的な制御ブロック図および、図４に示したフローチャートに基づき説明する。
【００２３】
ユーザが製氷機に電源を印加すると、図４のように構成された、本発明による初期動作制御方法を採用した製氷機の制御装置１００は、閉鎖検知センサ１３０及び開放検知センサ１４０から出力される検知信号が伝達されて製氷槽の現在の位置を把握する。
【００２４】
この際、閉鎖検知センサ１３０及び開放検知センサ１４０は、製氷ユニットフレーム１１２に設置される。ところが、製氷ユニットフレーム１１２に回動自在に設置される製氷槽組立体１２０が閉鎖位置にある場合は、閉鎖検知センサ１３０が検知信号を出力して、現在製氷槽１２１が製氷位置が至っていることを制御装置１００に知らせる。そして、製氷槽組立体１２０が開放位置にある場合は、開放検知センサ１４０が検知信号を出力して、現在製氷槽１２１が開放されていることを制御装置１００に知らせる（ステップＳ４１０）。
【００２５】
従って、もし閉鎖検知センサ１３０において、製氷槽組立体１２０が製氷位置に存在することを確認すれば、制御装置１００は製氷槽組立体１２０を開放して製氷槽１２１に残っている製氷水を取り除き、冷却突起が貯氷庫１１に露出されるように、製氷槽回転ユニット１５０に作動命令を出す。製氷槽回転ユニット１５０は、開放検知センサ１４０から検知信号が出力されるまで、製氷槽組立体１２０を旋回軸１２４を中心として回転させる（ステップＳ４２０）。
【００２６】
このように製氷槽組立体１２０が旋回軸１２４を中心として回動して、製氷ユニット１１０が完全に開放されると、制御装置１００は所定の氷分離手段１６０に作動信号を印加して、製氷ユニット１１０に残っている氷を取り除く。氷分離手段１６０は、高温高圧の冷媒を蒸発機２３に循環させるホットガス方式が用いられうる。
【００２７】
ちなみに、蒸発機２３には圧縮機３１を通過した高熱冷媒が凝縮機３２を経ることなくバイパスされて流入される。これにより、冷却突起が約１０℃に加熱されるとともに、冷却突起の周りの決氷面にて解氷が生じ、生成された氷が冷却突起から分離されて貯氷庫１１に落下する（ステップＳ４３０）。
【００２８】
ステップＳ４３０において、製氷ユニット１１０に残った氷が除去されると、制御装置１００は製氷槽回転ユニット１５０へ再び作動信号を印加して、製氷槽組立体１２０を逆回転させて製氷位置に復帰させる。この場合、製氷槽回転ユニット１５０は、製氷槽組立体１２０が製氷位置に到達するまで作動するが、製氷槽組立体１２０が製氷位置に到達すると、閉鎖検知センサ１３０は製氷槽支持プレート１２２に埋設されたマグネット１３１を検知して検知信号を制御装置１００に出力する。この信号を受けた制御装置１００は、製氷槽回転ユニット１５０に停止信号を出力して回転を停止することになる（ステップＳ４４０）。
【００２９】
以上説明したように、製氷機の初期動作の制御が終了すると、制御装置１００は製氷ユニット１１０に氷を作るための動作を指示することになる。すなわち、製氷槽１２１には、給水管１２を介して給水が行われ、製氷のための一連の工程が行われる。
【００３０】
つまり、製氷水の供給が完了した後、カムモータ１１１が作動すれば、カム部材（図示せず）が製氷槽１２１の突出部を交互に押圧する。製氷槽１２１はカム部材の押圧力とバネ１２３の弾性反発力によって所定距離、たとえば１５ｍｍだけ上下に揺動し、製氷槽１２１内の製氷水もやはり冷却突起に対し上下に揺動する。そして、蒸発機２３内における冷媒の熱交換により氷点以下に冷却された冷却突起の周りには製氷水が決氷し始める。このとき、冷却突起の決氷面にあった気泡は、製氷水の揺動によって取り除かれるので、冷却突起の周りには透明な氷が成長する（ステップＳ４５０）。
【００３１】
したがって、ステップＳ４５０において製氷作業が終了すれば、ステップＳ４３０で説明したように、生成された氷を製氷ユニット１１０の冷却突起で分離して、貯氷庫１１に貯蔵する（ステップＳ４６０）。
【００３２】
一方、ステップＳ４１０において、製氷槽組立体１２０が開放されたものと判断されると、制御装置１００はまっすぐステップＳ４３０に進み、製氷ユニット１１０に残留しているかもしれない氷を氷分離手段１６０を用いて氷を取り除く。即ち、これは、長時間電源が供給されない場合には製氷ユニット１１０にて生成中にあった氷は全部溶けて、もう製氷ユニット１１０に残存する氷がないわけであるが、もし電源が切れてからあまり長い時間が経たないものであれば、製氷ユニット１１０に氷が残存することもあり得るからである。このため、前述したホットガス方式などを用いて、冷却突起を循環的に加熱して、冷却突起の周りの決氷面を解氷させ、生成中の氷を冷却突起から分離させ、貯氷庫１１に貯蔵する。以下は、前述した製氷段階と同様であるため、説明を省略する。
【００３３】
【発明の効果】
以上説明したように、本発明による製氷槽の位置検知センサを用いた製氷機の初期動作制御方法によれば、製氷槽の位置検知センサにより製氷槽の現在の位置を把握して、製氷ユニットに残留した製氷水及び生成中の氷を取り除いた後、製氷動作を開始するため、製氷機の誤作動及び、更にこれによる製氷機の破損を防止することができる。
【００３４】
以上、本発明を本発明の原理を例示するための好ましい実施の形態について図示しかつ説明したが、本発明はこれに限定されるものではない。かえって、添付の特許請求の範囲の思想及びカテゴリを逸脱しない範囲内で、本発明に対する多数の変更及び修正が可能であることは当業者ならばよく理解できることである。従って、かかる全ての適宜の変更及び修正、更に均等物も本発明の範囲に属するものと見なされるべきである。

[Problems to be solved by the invention]
However, during the use of the ice maker configured as described above, the operation of the ice maker may be stopped due to a power failure or a user power cutoff. In this case, ice that is being generated may remain in the ice making unit 20.

Become.
[0007]
In addition, when the ice being produced is left in the ice making section 20, when the ice making is restarted, ice is further generated on the ice being produced, so that the quality of the ice is deteriorated. In addition to the fact that ice cannot be obtained, there is a problem that the ice being produced hits the ice making tank 27 when the ice making tank 27 swings, causing a mechanical impact.
[0008]

[0015]
The ice making tank 121 is installed above the ice making tank assembly 120 so as to be able to move up and down. For this purpose, a spring 123 is provided between the ice making tank 121 and the ice making tank support plate 122. On the upper surface of the ice making tank 121, a plurality of concave portions filled with ice making water are formed. Further, ice is not made on one side of the upper surface of the ice making tank 121, and a drainage channel for draining residual water is formed. When the ice making tank support plate 122 is rotated downward at an angle of 90 degrees, water is discharged through the drainage channel.

Desirably, the closing detection sensor 130 detects a magnet embedded in a portion of the ice making tank support plate 122 corresponding to the position where the closing detection sensor 130 is provided, and determines whether the ice making tank assembly 120 is closed.
[0021]
The opening detection sensor 140 is installed on the ice making unit frame 112, and outputs the detection signal when the ice making tank support plate 122 reaches the maximum open position. It is desirable to be installed in the vicinity of substantially the center of. Further, a magnet is embedded in the ice making tank supporting plate 122 at a position corresponding to the opening detection sensor 140. Therefore, the predetermined control unit recognizes the case where the magnet approaches the opening detection sensor 140 as the opening state of the ice making tank support plate 122.
[0022]
Next, a method for controlling the initial operation of the ice making machine according to the present invention will be described with reference to the schematic control block diagram of the ice making machine shown in FIG. 3 and the flowchart shown in FIG.
[0023]
When a user applies power to the ice maker, the ice maker control device 100 configured as shown in FIG. 4 and employing the initial operation control method according to the present invention outputs from the closing detection sensor 130 and the opening detection sensor 140. The detection signal is transmitted to grasp the current position of the ice making tank.
[0024]
At this time, the closing detection sensor 130 and the opening detection sensor 140 are installed on the ice making unit frame 112. However, when the ice making tank assembly 120 rotatably installed on the ice making unit frame 112 is in the closed position, the closing detection sensor 130 outputs a detection signal, and the ice making tank 121 is now at the ice making position. To the control device 100. If the ice making tank assembly 120 is at the open position, the opening detection sensor 140 outputs a detection signal to notify the control device 100 that the ice making tank 121 is currently open (step S410).
[0025]
Therefore, if the closing detection sensor 130 confirms that the ice making tank assembly 120 is at the ice making position, the control device 100 opens the ice making tank assembly 120 to remove the ice making water remaining in the ice making tank 121. Then, an operation command is issued to the ice making tank rotating unit 150 so that the cooling projection is exposed to the ice storage 11. The ice-making tank rotating unit 150 rotates the ice-making tank assembly 120 about the turning shaft 124 until the detection signal is output from the opening detection sensor 140 (Step S420).
[0026]
As described above, when the ice making tank assembly 120 rotates about the pivot shaft 124 and the ice making unit 110 is completely opened, the control device 100 applies an operation signal to the predetermined ice separating means 160, and The ice remaining in the unit 110 is removed. As the ice separating means 160, a hot gas method in which a high-temperature and high-pressure refrigerant is circulated to the evaporator 23 can be used.
[0027]
Incidentally, the high-temperature refrigerant that has passed through the compressor 31 is bypassed and flows into the evaporator 23 without passing through the condenser 32. As a result, the cooling protrusions are heated to about 10 ° C., and ice is melted on the ice surface around the cooling protrusions, and the generated ice is separated from the cooling protrusions and falls into the ice storage 11 (step S430). ).
[0028]
In step S430, when the ice remaining in the ice making unit 110 is removed, the control device 100 again applies an operation signal to the ice making tank rotating unit 150 to reversely rotate the ice making tank assembly 120 to return to the ice making position. . In this case, the ice maker rotating unit 150 operates until the ice maker assembly 120 reaches the ice making position, but when the ice maker assembly 120 reaches the ice making position, the closing detection sensor 130 is embedded in the ice maker supporting plate 122. The detected magnet 131 is detected and a detection signal is output to the control device 100. Upon receiving this signal, the control device 100 outputs a stop signal to the ice making tank rotating unit 150 to stop the rotation (step S440).
[0029]
As described above, when the control of the initial operation of the ice making machine is completed, the control device 100 instructs the ice making unit 110 to perform an operation for making ice. That is, water is supplied to the ice making tank 121 through the water supply pipe 12, and a series of steps for ice making are performed.
[0030]
That is, when the cam motor 111 is operated after the supply of the ice making water is completed, the cam member (not shown) alternately presses the projecting portions of the ice making tank 121. The ice making tank 121 swings up and down a predetermined distance, for example, 15 mm, by the pressing force of the cam member and the elastic repulsive force of the spring 123, and the ice making water in the ice making tank 121 also swings up and down with respect to the cooling projections. Then, ice making water starts to freeze around the cooling projections cooled to below the freezing point by heat exchange of the refrigerant in the evaporator 23. At this time, the bubbles on the ice surface of the cooling projections are removed by the swing of the ice making water, so that transparent ice grows around the cooling projections (step S450).
[0031]
Therefore, when the ice making operation is completed in step S450, the generated ice is separated by the cooling projections of the ice making unit 110 and stored in the ice storage 11 as described in step S430 (step S460).
[0032]
On the other hand, if it is determined in step S410 that the ice making tank assembly 120 has been opened, the control device 100 proceeds directly to step S430 to remove the ice remaining in the ice making unit 110 by the ice separating means 160. Use to remove ice. In other words, this means that if power is not supplied for a long time, all the ice that was being generated in the ice making unit 110 has melted and there is no longer any ice remaining in the ice making unit 110. This is because ice may remain in the ice making unit 110 if a long time has not passed. For this reason, the cooling projections are cyclically heated using the above-described hot gas method or the like, so that the ice surface around the cooling projections is thawed, the ice being generated is separated from the cooling projections, and the ice storage 11 Store in. The following is the same as the above-described ice making stage, and thus the description is omitted.
[0033]
【The invention's effect】

Since the ice making operation is started after the remaining ice making water and the ice being generated are removed, malfunction of the ice making machine and further damage to the ice making machine due to the malfunction can be prevented.
