Description

【0001】
【発明の属する技術分野】
本発明は、製氷部と循環ポンプと貯水タンクとからなる循環給水経路を備えた自動製氷装置に関するものである。
【0002】
【従来の技術】
近年、飲食店舗では、飲食用の透明氷が短時間で大量にできる業務用自動製氷機が普及している。
【0003】
従来の洗浄機能を備えた自動製氷装置としては、通電された初回製氷工程時のみ自動的に洗浄を行うものがある(例えば、特許文献1参照。)。
【0004】
以下、図面を参照しながら上記従来の自動製氷装置を説明する。
【0005】
図6は、従来の自動製氷装置の一部を破断した側面図である。図7は、従来の自動製氷装置の運転に係わる制御工程のタイムチャート図である。
【0006】
図6に示すように、従来の自動製氷装置は、下向きに開口した多数のセルを配置した製氷室51と、製氷室51の上壁面に配置された冷却パイプ52と、製氷室下方に間隔を開けて配置され、製氷室1の各セルに水を噴出する吐出口53と未凍結の水が回収される戻り口54を形成した水皿55と、水皿55下部に固定され戻り口54と連通している貯水タンク56と、貯水タンク56内の製氷用水を吐出口53に供給する循環ポンプ57と、水皿55を傾動及び復動させる駆動装置58と、水道と直結しており吐出部が水皿55の上方に配置された給水弁59とから構成されている。
【0007】
なお、図示しないが、製氷室51を冷却するためのコンプレッサと、凝縮器の熱を奪う送風手段と、脱氷時に冷却パイプ52を温めるホットガスの供給・停止を行うホットガス弁がある。
【0008】
以上のように構成された自動製氷装置について、以下その動作を図7のタイムチャートを参照して説明する。
【0009】
製氷を行う場合、コンプレッサと送風手段運転が開始されることにより低温冷媒が冷却パイプ52を流れ、製氷室51を冷却しはじめる。このとき、給水弁59が開き、水皿55の表面に水道水が流れ、戻り口54を通り、貯水タンク56へ供給される。水位が所定位置になると給水弁59が閉じ給水が完了する。給水後、循環ポンプ57が運転しはじめ、貯水タンク56に貯えられた水道水は加圧され水皿55を通り、吐出口53より噴出する。吐出した水は製氷室51のセル内側上面に衝突し、壁面に沿うように流れる。
【0010】
セルは低温冷媒によって冷却されているため、セル内側壁面より凍結しはじめ、未凍結の水は水皿55表面に落下し、戻り口54を通過し、貯水タンク56に戻る。製氷が完了すると、ホットガス弁が開き、冷却パイプ52にホットガスが流れ、製氷室51壁面より氷が融解させることによってセルと氷の付着力を弱め、自重により氷を落下させることにより離氷を行う。
【0011】
ホットガス弁の開きにあわせて、駆動装置58により水皿55が傾動し、貯水タンク56内の水を排出すると同時に、給水弁59を開き一定時間水皿55に流水させ水皿55表面の残氷を融解させる。離氷が完了すると、駆動装置58により水皿55が復動し水平位置に戻り、再び製氷しはじめる。
【0012】
ここで、全停止している状態から、電源をONした直後の場合には、循環ポンプ57の運転を氷が成長しない短い時間運転とし離氷動作を行うことによって、自動製氷装置内を流水洗浄し製氷を始める。また、製氷運転を停止するには電源をOFFにしなければならない。

【発明が解決しようとする課題】
しかしながら、上記従来の構成は、流路内の洗浄が電源ONした初回のみであり、製氷運転を停止するには電源をOFFにして自動製氷装置を全停止しているため、長期製氷運転停止時には水循環経路内で水の腐敗や水垢が発生し、製氷運転再開時に、流水洗浄のみでは水垢や水の腐敗臭を完全に取り去ることが困難になり、不衛生な氷ができるという欠点があった。
【0015】
本発明では、従来の課題を解決するもので、製氷装置が長期停止した場合でも水の腐敗や水垢の発生、ゴミの堆積をなくすことができる自動製氷装置を提供することを目的とする。

【0022】
【発明の実施の形態】
以下、本発明による自動製氷装置の実施の形態について、図面を参照にしながら説明する。
【0023】
(実施の形態1)
図1は本発明の実施の形態1による自動製氷装置のシステム構成図である。図2は自動製氷装置の要部断面図である。図3は自動製氷装置の製氷動作に係わる制御工程のタイムチャート図である。図4は、自動製氷装置の定期洗浄運転に係わる制御工程のタイムチャート図である。図5は、自動製氷装置の制御工程の動作フロー図である。
【0024】
図1において、自動製氷装置1には、主電源をON−OFFするブレーカー2と、ブレーカ2の二次側に設けられた手動スイッチ3と自動製氷装置1の運転を制御する制御手段4が設けられている。コンプレッサ5の吐出口には吐出配管6が接続されており、吐出配管6出口には冷媒を冷却する凝縮器7が接続されている。
【0025】
凝縮器7出口には液配管8が、液配管8出口にはゴミや水分を吸着させるドライア9が接続されている。ドライア9出口には、キャピラリーチューブ10が接続されておりキャピラリーチューブ10出口には製氷を行う製氷部11と接合された冷却パイプ12が接続されている。冷却パイプ12出口には、液体を分離するアキュームレータ13が接続されている。
【0026】
アキュームレータ13出口は、コンプレッサ5吸入口と接続した吸入配管14で接続されており、冷媒循環経路を形成する。吐出配管6には、バイパス配管15が接続しており、バイパス配管15にはバイパス配管の開閉を行うホットガス弁16が配置されている。バイパス配管11出口は、キャピラリ−チューブ10出口で冷媒循環経路と合流しており、コンプレッサ5に戻るホットガス経路を形成している。
【0027】
凝縮器7近傍には、凝縮器7の放熱を促進させるために送風手段17と外気温検知サーミスタ18が配置されている。製氷部11には、下方に向かって開口し上面が冷却パイプ12と接合されている複数のセル19と、セル19外周に接触したセル温度検知サーミスタ20が取り付けられている。製氷部7の下方には少し間隔をおいて、セル19へ製氷水を供給する貯水タンク21と貯水タンク21の傾動と復動を行う駆動装置22と貯水タンク21内の製氷水の加圧を行う循環ポンプ23が配置されている。
【0028】
給水タンク21上方にはセル19と少し間隔を置いて、水道と直結した給水弁24が配置されている。貯水タンク21は、上部の水皿部31と下部の貯水部32とから構成されており、循環ポンプ17吸入口に貯水部32、循環ポンプ19吐出口に水皿部31が連結されており、製氷部7と貯水タンク17と循環ポンプ19によって循環給水経路が形成されている。
【0029】
水皿部31は各セル15内面に製氷用水を噴出するための噴出口33と、噴出口33近傍で未凍結水を貯水部32に戻す戻り口34が設けられている。
【0030】
なお、本実施例では手動スイッチ2は、ブレーカ1と制御手段3の間に配置したが、制御手段3の基盤上に置いても良い。
【0031】
以上のように構成された自動製氷装置について、以下その動作を図3、図4のタイムチャートと図5の動作フローを参照して説明する。
【0032】
通常、製氷運転は給水動作と製氷動作と離氷動作から成り立っており、まず給水動作では、コンプレッサ5と送風手段17を稼働させることで、吐出配管6に冷媒が流れ、凝縮器7と送風手段17により冷却された冷媒は、キャピラリーチューブ6の水分・ゴミの詰まりを防ぐため、ドライア9を通過させた後、キャピラリーチューブ10へ流入する。
【0033】
キャピラリーチューブ10を通過することにより、冷却パイプ12では圧力が低下するため冷媒が低温蒸発して冷却パイプ12を冷却する。冷却パイプ12を通過した冷媒は、アキュームレータ13によって液分離され、気化した冷媒のみコンプレッサ5へ戻る。ここで、冷却パイプ12は低温冷媒によって冷却されるため、接合されているセル19上部より冷却される。
【0034】
コンプレッサ5と送風手段17の稼働と同時に、貯水タンク21は駆動装置22により上昇しはじめ、給水弁24が開き、水皿部31の戻り口34より貯水部32に水が供給される。ここで給水動作が終了する。
【0035】
次に製氷動作では、貯水タンク21が水平になると上昇を停止し、給水弁24を閉じ、循環ポンプ23が駆動しはじめる。循環ポンプ23によって貯水部32の水は加圧され、吐出口33より各セル19内側に吐出される。吐出された水は、セル19内側上面に衝突し、セル19側面を沿って流れる。セル19に衝突した水は、冷却パイプ12を流れる低温冷媒によって壁面より凍結しはじめ、未凍結水は水皿部31表面に落下し、戻り口34を通過し貯水部32に戻る。この未凍結水には、氷が水中の不純物を排出しながら成長するため、不純物が濃縮されている。製氷完了温度をセル温度検知サーミスタ20が検知すると、製氷動作が終了する。
【0036】
次に離氷動作では、送風手段17と循環ポンプ23が停止し、貯水タンク21は下降しはじめ、貯水部32の残水を排出する。同時にホットガス弁16が開き、バイパス配管15にホットガスが流れ、冷却パイプ12が温められる。冷却パイプによりセル19壁面が温められることにより氷が融解しはじめる。
【0037】
貯水タンク21が所定角度まで下降し停止すると、給水弁24が開き、水皿部31表面の残氷の融解と洗浄を行い、所定時間洗浄を経過すると、給水弁24を閉じる。セル19と氷の付着力が小さくなり、自重により氷が落下したことで、セル19温度の急激な上昇をセル温度検知サーミスタ20により検知すると、ホットガス弁16を閉じ、ここで離氷動作が終了する。
【0038】
以上の給水動作と製氷動作と離氷動作を繰り返すことで製氷運転が行なわれる。
【0039】
従来、製氷運転を停止させる場合、ブレーカを操作して製氷機を全停止していた。本実施例においては、ブレーカ2とは別に手動スイッチ20を設けたことで製氷運転のみをON−OFFできることとした。以下、手動スイッチ20をOFFした場合の動作について説明する。
【0040】
まず、製氷動作中に手動スイッチをOFFにして待機モードに切り替わると、製氷動作を停止して、離氷動作を行い、離氷動作が終了すると、コンプレッサ5を停止させる。コンプレッサ5を停止させることにより、給水タンク21が下降停止した状態で全停止する。全停止後すぐに、定期洗浄運転を行う。
【0041】
定期洗浄運転は、ブレーカ2がONした時に行われる流水動作と給水タンク21が下降を停止した状態での全停止から成り立っており、まず、流水動作では、貯水タンク21を上昇させると同時に給水弁24を開き、水道水を水皿部31の戻り口34を通過させることで貯水部32に供給する。
【0042】
次に、貯水タンク21が水平になると上昇を停止し、給水弁24を閉じ、循環ポンプ23を駆動させる。循環ポンプ23によって貯水部32の水は加圧され水皿部31内部を通過し、吐出口33より各セル19内側に吐出される。吐出された水はセル19内側上面に衝突後、セル19内側面を沿って流れ、水皿部31の戻り口34より貯水部32に戻る。
【0043】
次に一定時間循環ポンプ23を駆動させることで循環給水経路が流水洗浄され、洗浄が終了すると循環ポンプ23を停止し、貯水タンク21を駆動装置22によって下降させて水を排出する。貯水タンク21が所定角度になると下降を停止し、貯水タンク内の不純物が濃縮された残水が貯水タンク21外へ排出され、流水動作が終了する。
【0044】
流水動作後、貯水タンク21は下降した状態で所定期間全停止し、再び流水動作を行う。このように流水動作と全停止を繰り返すことで定期洗浄運転を行う。ここで、全停止期間は、セル温度検知サーミスタ20もしくは外気温検知サ−ミスタ18で検知した温度によって変化し、温度が高い場合、水の腐敗や残水の蒸発による水垢の発生が早くなるため、停止時間を短くする。
【0045】
ただし、全停止期間はゴミの堆積や低温での水の腐敗の発生を考え、最低一週間に1回洗浄を行う。
【0046】
また、切り替えが離氷動作中の場合には、離氷動作を継続し、離氷動作が終了すると、コンプレッサ5を停止させ、給水タンク21が下降停止した状態で全停止し、定期洗浄運転を行う。
【0047】
また、切り替えが給水動作中の場合には、コンプレッサ5と送風手段17を停止させ、給水弁24を閉じ、貯水タンク21を下降させる。所定角度貯水タンク21が下降すると停止し、貯水タンク21が下降した状態で全停止する。全停止後は定期洗浄運転を行う。
【0048】
また、切り替えが流水動作中の場合には、循環ポンプ23を停止させ、給水弁24を閉じ、貯水タンク21を下降させる。所定角度貯水タンク21が下降すると停止し、貯水タンク21が下降した状態で全停止する。全停止後は定期洗浄動作を行う。
【0049】
以上のように本実施の形態の自動製氷装置は、主電源をON−OFFするブレーカ2と、ブレーカの二次側に配置された手動スイッチ3と、自動製氷装置1を制御する制御手段4と、冷却手段を備え製氷を行う製氷部11と製氷用水を溜めておく貯水タンク21と前記貯水タンク21内の水を製氷部11に送る循環ポンプ23とからなる循環給水経路と、製氷部11の温度検知するセル温度検知サーミスタ20と、外気温を検知する外気温検知サーミスタ18からなり、給水動作と製氷動作と離氷動作からなる製氷運転を繰り返す自動製氷装置において、手動スイッチ3を切り替えることにより製氷運転の運転・停止を選択できるものであり、製氷運転のみを停止することができる。
【0050】
また、本実施の形態の自動製氷装置は、手動スイッチ3の切り替えにより製氷運転の停止を選択した待機モード時には、少なくとも循環ポンプ23を定期的に稼働させ循環給水経路内に流水する流水動作と停止動作からなる洗浄動作を定期的に繰り返す定期洗浄運転を行うものであり、製氷運転を停止した状態で定期的に循環給水経路内に流水するので、製氷運転停止時の水の腐敗、水垢の発生とゴミの堆積を防ぐことができ、製氷再開時に衛生的な氷を提供することができる。
【0051】
また、本実施の形態の自動製氷装置は、定期洗浄運転開始時に、流水動作を行うものであり、製氷動作もしくは離氷動作後の不純物の多い貯水タンク21内の残水を排出するので、水の腐敗や水垢の発生しやすい不純物の多い水を循環給水経路内から排出することができる。
【0052】
また、本実施の形態の自動製氷装置は、定期洗浄運転中、セル温度検知サーミスタ20もしくは外気温度サーミスタ18の検知温度により流水停止時間を変化するものであり、水の腐敗や水垢の発生に影響を与える温度によって流水回数が変化するので、温度変化しても流路内の残水が腐敗せず、循環給水経路内を清潔に保つことができる。
【0053】
また、本実施の形態の自動製氷装置は、流水動作は一週間に一回以上行うものであり、循環給水経路内への流水の長期停止を防ぐことができるので、流水回数の減少する低温時の水垢の発生やゴミの堆積を防ぎ、循環給水経路内を清潔に保つことができる。
【0054】
また、本実施の形態の自動製氷装置は、待機モードから製氷運転を行う製氷モードに切り替え時は、製氷開始前に循環給水経路内に流水するものであり、循環経路内の残水と製氷用水の混合水による製氷を防ぐので、衛生的な水で製氷を行うことができる。
【0055】

BACKGROUND OF THE INVENTION
The present invention relates to an automatic ice making device having a circulation water supply path composed of an ice making unit, a circulation pump, and a water storage tank.
[0002]
[Prior art]
2. Description of the Related Art In recent years, business-use automatic ice makers that can produce a large amount of transparent ice for eating and drinking in a short time have become widespread in restaurants.
[0003]
As an automatic ice making device having a conventional washing function, there is an automatic ice making device that automatically performs washing only during an energized initial ice making process (see, for example, Patent Document 1).
[0004]
Hereinafter, the conventional automatic ice making device will be described with reference to the drawings.
[0005]
FIG. 6 is a side view in which a part of a conventional automatic ice making device is broken. FIG. 7 is a time chart of a control process related to the operation of a conventional automatic ice making device.
[0006]
As shown in FIG. 6, the conventional automatic ice making apparatus has an ice making chamber 51 in which a large number of downwardly opening cells are arranged, a cooling pipe 52 arranged on the upper wall surface of the ice making chamber 51, and a space below the ice making chamber. A water tray 55 which is disposed open and has a discharge port 53 for ejecting water into each cell of the ice making chamber 1 and a return port 54 for collecting unfrozen water, and a return port 54 fixed to the bottom of the water plate 55. A water storage tank 56 that is in communication, a circulation pump 57 that supplies ice-making water in the water storage tank 56 to the discharge port 53, a drive device 58 that tilts and returns the water tray 55, and a discharge unit that is directly connected to the water supply. Is composed of a water supply valve 59 disposed above the water tray 55.
[0007]
Although not shown in the figure, there are a compressor for cooling the ice making chamber 51, a blowing means for removing heat from the condenser, and a hot gas valve for supplying / stopping hot gas for heating the cooling pipe 52 at the time of deicing.
[0008]
The operation of the automatic ice making device configured as described above will be described below with reference to the time chart of FIG.
[0009]
When ice making is performed, the operation of the compressor and the air blowing means is started, so that the low-temperature refrigerant flows through the cooling pipe 52 and starts cooling the ice making chamber 51. At this time, the water supply valve 59 is opened, tap water flows on the surface of the water tray 55, passes through the return port 54, and is supplied to the water storage tank 56. When the water level reaches a predetermined position, the water supply valve 59 is closed and the water supply is completed. After the water supply, the circulation pump 57 starts to operate, and the tap water stored in the water storage tank 56 is pressurized and passes through the water tray 55 and is ejected from the discharge port 53. The discharged water collides with the cell inner upper surface of the ice making chamber 51 and flows along the wall surface.
[0010]
Since the cell is cooled by the low-temperature refrigerant, it begins to freeze from the inner wall surface of the cell, and unfrozen water falls to the surface of the water dish 55, passes through the return port 54, and returns to the water storage tank 56. When the ice making is completed, the hot gas valve opens, the hot gas flows into the cooling pipe 52, the ice melts from the wall surface of the ice making chamber 51 to weaken the adhesion between the cell and ice, and the ice is dropped by dropping its own weight. I do.
[0011]
In accordance with the opening of the hot gas valve, the water tray 55 is tilted by the driving device 58 and the water in the water storage tank 56 is discharged. At the same time, the water supply valve 59 is opened and the water tray 55 is allowed to flow for a certain period of time. Thaw the ice. When the ice removal is completed, the water tray 55 is moved back by the driving device 58 to return to the horizontal position, and ice making starts again.

[0030]
In the present embodiment, the manual switch 2 is arranged between the breaker 1 and the control means 3, but may be placed on the base of the control means 3.
[0031]
The operation of the automatic ice making apparatus configured as described above will be described below with reference to the time charts of FIGS. 3 and 4 and the operation flow of FIG.
[0032]
Usually, the ice making operation is composed of a water supply operation, an ice making operation and an ice removing operation. First, in the water supply operation, the refrigerant flows into the discharge pipe 6 by operating the compressor 5 and the air blowing means 17, and the condenser 7 and the air blowing means. The refrigerant cooled by 17 flows through the dryer 9 and then flows into the capillary tube 10 in order to prevent the capillary tube 6 from being clogged with moisture and dust.
[0033]
By passing through the capillary tube 10, the pressure in the cooling pipe 12 decreases, so the refrigerant evaporates at a low temperature and cools the cooling pipe 12. The refrigerant that has passed through the cooling pipe 12 is liquid-separated by the accumulator 13, and only the vaporized refrigerant returns to the compressor 5. Here, since the cooling pipe 12 is cooled by the low-temperature refrigerant, the cooling pipe 12 is cooled from the upper part of the joined cell 19.
[0034]
Simultaneously with the operation of the compressor 5 and the air blowing means 17, the water storage tank 21 starts to rise by the drive device 22, the water supply valve 24 opens, and water is supplied to the water storage section 32 from the return port 34 of the water tray section 31. The water supply operation ends here.

Next, in the ice making operation, when the water storage tank 21 becomes horizontal, the ascent is stopped, the water supply valve 24 is closed, and the circulation pump 23 starts to be driven. The water in the water storage section 32 is pressurized by the circulation pump 23 and discharged from the discharge port 33 to the inside of each cell 19. The discharged water collides with the inner upper surface of the cell 19 and flows along the side surface of the cell 19. The water that has collided with the cell 19 begins to freeze from the wall surface by the low-temperature refrigerant flowing through the cooling pipe 12, and the unfrozen water falls to the surface of the water dish unit 31, passes through the return port 34, and returns to the water storage unit 32. In this unfrozen water, since the ice grows while discharging impurities in the water, the impurities are concentrated. When the cell temperature detection thermistor 20 detects the ice making completion temperature, the ice making operation is finished.
[0036]
Next, in the deicing operation, the blowing means 17 and the circulation pump 23 are stopped, the water storage tank 21 starts to descend, and the remaining water in the water storage section 32 is discharged. At the same time, the hot gas valve 16 is opened, hot gas flows into the bypass pipe 15, and the cooling pipe 12 is warmed. As the wall surface of the cell 19 is warmed by the cooling pipe, the ice begins to melt.
[0037]
When the water storage tank 21 descends to a predetermined angle and stops, the water supply valve 24 opens, the remaining ice on the surface of the water tray 31 is melted and cleaned, and when the predetermined time has passed, the water supply valve 24 is closed. When the cell temperature detection thermistor 20 detects a sudden rise in the temperature of the cell 19 because the ice adheres to the cell 19 and the ice falls due to its own weight, the hot gas valve 16 is closed, and the deicing operation is performed. finish.
