Description

本発明は、アイスシェルターや氷室等の貯氷施設内の氷が融解した水を人工的に再凍結させるために使用する製氷車及びその使用方法並びに貯氷施設に関する。   The present invention relates to an ice making vehicle used for artificially refreezing water in which ice in an ice storage facility such as an ice shelter or an ice chamber is melted, a method for using the ice making vehicle, and an ice storage facility.

エネルギー資源が乏しい我国は、地域に賦存する自然エネルギーを見直し、国全体の使用率を高めるため、昨年、再生可能エネルギー全量買い取り制度をスタートさせている。再生可能エネルギーの一つである雪氷エネルギーは、風力、太陽光、バイオマス等の他の再生可能エネルギーと比べると、寒冷地においてさえ未だ利用が進められていない状況である。   Japan, which lacks energy resources, started a system for purchasing all renewable energy last year in order to review the renewable energy existing in the region and increase the overall usage rate. Snow and ice energy, which is one of the renewable energies, is not yet being used even in cold regions compared to other renewable energies such as wind, solar and biomass.

雪氷エネルギーを利用した施設として、青果物の長期保存や冷房のために自然氷の潜熱を利用した施設(アイスシェルターとも称されている)が知られている(特許文献1等)。アイスシェルターは、断熱庫内に収容したタンク内の水を、冬季の自然冷気を利用して凍結させ、その融解潜熱によって通年に亘って温度0℃、湿度100%の庫内環境を維持し、農産物の貯蔵、家屋の除湿冷房に利用するものである。特許文献1のアイスシェルターは固定設置型であるが、特許文献2に記載の移動式氷室は、搬送可能なコンテナを氷室として用いることにより、冬季に寒冷地で氷を自然凍結させ、夏季には、必要とされる場所にコンテナを移送して利用することを可能としたものである。   As a facility using snow and ice energy, a facility (also referred to as an ice shelter) that uses the latent heat of natural ice for long-term preservation and cooling of fruits and vegetables is known (Patent Document 1, etc.). The ice shelter freezes the water in the tank accommodated in the heat insulation box using natural cold air in winter, and maintains the internal environment at a temperature of 0 ° C. and humidity of 100% throughout the year by its melting latent heat. It is used for storage of agricultural products and dehumidification and cooling of houses. Although the ice shelter of Patent Document 1 is a fixed installation type, the mobile ice chamber described in Patent Document 2 uses a transportable container as an ice chamber, so that ice is naturally frozen in the cold region in winter and in the summer The container can be transported to a required place and used.

しかしながら、アイスシェルターや氷室等の貯氷施設には、次のような問題点がある。
貯氷施設における従来の製氷方式は、冬季の自然冷気を利用した自然製氷であるので、1年に1回しか行うことができない。1回の製氷により得られた氷により、次年の冬季までの間、所定の冷却効果を維持するためには、途中で氷が不足しないように余裕を見て当初の氷の量を確保しなければならない。そのために、貯氷施設の規模を大きくせざるを得ず、その結果、施設構築のイニシャルコストが多大となり、システム全体のコストが割高となっていた。
However, ice storage facilities such as ice shelters and ice rooms have the following problems.
Since the conventional ice making method in the ice storage facility is natural ice making using natural cold air in winter, it can be performed only once a year. In order to maintain the prescribed cooling effect until the winter of the following year with the ice obtained by one ice-making, secure the initial ice amount with a margin so as not to run out of ice on the way. There must be. For this reason, the scale of the ice storage facility has to be increased. As a result, the initial cost for constructing the facility has become large, and the cost of the entire system has become expensive.

一つの解決手段として、貯氷施設の規模を小さくしてイニシャルコストを低減し、その代わりに、電気冷凍機を併用することにより貯氷施設による冷却効果の不足分を補うというハイブリッド方式が採られている。しかしながら、ハイブリッド方式は、電気冷凍機を稼働させるための十分な電力が得られる場所でのみ採用可能である。   One solution is to reduce the initial cost by reducing the scale of the ice storage facility, and instead use a hybrid system that compensates for the lack of cooling effect of the ice storage facility by using an electric refrigerator. . However, the hybrid method can be used only in a place where sufficient electric power for operating the electric refrigerator can be obtained.

上記の現状に鑑み、本発明は、貯氷施設内の氷が融解して冷却機能が低下した際に、融解により生じた水を人工的に再凍結させることができ、かつ、貯氷施設の設置場所に関わらず再凍結を実行することができる製氷車、製氷車の使用方法並びに製氷車に対応可能な貯氷施設を提供することを目的とする。   In view of the above situation, the present invention can artificially refreeze the water generated by melting when the ice in the ice storage facility melts and the cooling function is reduced, and the ice storage facility installation location It is an object of the present invention to provide an ice making vehicle that can perform re-freezing regardless of the method, a method of using the ice making vehicle, and an ice storage facility that can handle the ice making vehicle.

上記課題を解決すべく、本発明は、以下の構成を提供する。なお、括弧内の数字は、後述する図面中の符号であり、参考のために付するものである。
本発明の第1の態様は、貯氷施設(2)内の氷が融解した水を再凍結させるために使用する製氷車(1)であって、荷台(11A)を備えた運搬車両(11)と、前記荷台上に搭載された冷凍設備と、を備え、前記冷凍設備は、断熱された内部空間を有する冷却庫(12)と、前記冷却庫の外部に設置された室外機(13)及び前記冷却庫の内部に設置された室内機(14)から構成される冷凍機と、を有し、前記冷却庫(12)には、前記貯氷施設(2)との間でエアを循環させるための入気口(12D)及び排気口(12E)が形成されていることを特徴とす。
In order to solve the above problems, the present invention provides the following configurations. The numbers in parentheses are reference numerals in the drawings to be described later, and are attached for reference.
A first aspect of the present invention is an ice making vehicle (1) used for refreezing water in which ice in a ice storage facility (2) has melted, and a transport vehicle (11) provided with a loading platform (11A). And a refrigeration facility mounted on the cargo bed, wherein the refrigeration facility includes a cooler (12) having an insulated internal space, an outdoor unit (13) installed outside the cooler, and A refrigerator composed of an indoor unit (14) installed inside the refrigerator, and air is circulated between the ice storage facility (2) in the refrigerator (12). Inlet port (12D) and exhaust port (12E) are formed.

本発明の第2の態様は、上記製氷車の使用方法であって、前記入気口(12D)及び前記排気口(12E)と、前記貯氷施設(2)に形成した製氷車用排気口(21A)及び製氷車用入気口(21B)とをそれぞれ管状の連結手段(31、32)により連結した後、前記冷凍機を稼働し、前記冷却庫(12)と前記貯氷施設(2)の間でエアを循環させることにより、前記貯氷施設(2)内の氷が融解した水を再凍結させ、その後、前記連結手段を取り外すことを特徴とする。   A second aspect of the present invention is a method of using the ice making vehicle, wherein the air inlet (12D) and the exhaust port (12E) and an ice making vehicle exhaust port formed in the ice storage facility (2) ( 21A) and the ice making vehicle inlet (21B) are connected by tubular connecting means (31, 32), respectively, and then the refrigerator is operated, and the refrigerator (12) and the ice storage facility (2) The water in which the ice in the ice storage facility (2) is melted is re-frozen by circulating air between them, and then the connecting means is removed.

本発明の第3の態様は、氷を生成するための水を充填する多数のタンク(25)を収容し、冬季には前記タンク(25)に充填した水を自然の冷気により氷とし、夏季には前記タンク(25)内の氷による冷気を外部に取り出して利用する貯氷施設(2)であって、上記製氷車に形成された前記入気口(12D)及び前記排気口(12E)と、管状の連結手段(31、32)により着脱可能にそれぞれ連結される製氷車用排気口(21A)及び製氷車用入気口(21B)を形成したことを特徴とする。   The third aspect of the present invention accommodates a large number of tanks (25) filled with water for generating ice, and the water filled in the tanks (25) is converted into ice by natural cold air in the winter. Is an ice storage facility (2) that takes out and uses the cold air from the ice in the tank (25) to the outside, and includes the inlet (12D) and the exhaust port (12E) formed in the ice making wheel. The ice-making vehicle exhaust port (21A) and the ice-making vehicle inlet port (21B), which are detachably connected by the tubular connecting means (31, 32), are formed.

本発明による製氷車は、運搬車両に冷凍設備を搭載していることにより、貯氷施設の設置場所まで移動し、その場で貯氷施設内に水凍結用の冷気を送ることが可能である。次年の冬季までの間に貯氷施設内の氷が融解して冷却効果が低下してきたとき、製氷車を用いて融解した水を再凍結することにより、貯氷施設内の氷の量を、自然製氷した当初の量に戻すことができる。この人工的な再凍結は、必要に応じて繰り返し行うことができる。   Since the ice making vehicle according to the present invention has the refrigeration equipment mounted on the transport vehicle, it can move to the place where the ice storage facility is installed, and can send cold air for water freezing into the ice storage facility on the spot. When the ice in the ice storage facility melts by the winter of the following year and the cooling effect decreases, the amount of ice in the ice storage facility can be reduced by re-freezing the melted water using an ice-making wheel. It can be returned to its original quantity after ice making. This artificial refreezing can be repeated as necessary.

この結果、貯氷施設の貯氷量を従来よりも低減できるため、貯氷施設の規模を縮小することができる。これにより、施設構築のイニシャルコストを下げることとができる。また、1台の製氷車を、複数箇所の貯氷施設の再凍結に使用することができるので、それによっても低コストに実現可能である。   As a result, since the amount of ice stored in the ice storage facility can be reduced as compared with the conventional ice storage facility, the scale of the ice storage facility can be reduced. Thereby, the initial cost of facility construction can be reduced. In addition, since one ice making vehicle can be used for refreezing a plurality of ice storage facilities, it can be realized at a low cost.

貯氷施設を小規模とすることができるので、従来よりも狭い場所にも貯氷施設を設置して利用することが可能となる。   Since the ice storage facility can be made small, it is possible to install and use the ice storage facility in a narrower space than before.

また、貯氷施設の設置場所において十分な電力が得られない場合、例えば山間地や耕作地であっても、製氷車が赴くことで氷の再凍結が可能であるため、貯氷施設を設置することができる。   Also, if sufficient power is not available at the location of the ice storage facility, for example, even in mountainous or cultivated land, ice storage can be re-frozen by rolling an ice-making wheel. Can do.

既存の貯氷施設に適用する場合にも、貯氷施設に新たな電気工事を行うことは不要であり、貯氷施設が電力を提供する必要はない。既存の貯氷施設に製氷車用入気口と製氷車用排気口を形成するだけで、製氷車を利用することができる。   Even when applied to existing ice storage facilities, it is not necessary to perform new electrical work on the ice storage facility, and it is not necessary for the ice storage facility to provide power. An ice maker can be used simply by forming an inlet for an ice maker and an outlet for an ice maker in an existing ice storage facility.

Embodiments of the present invention will be described below with reference to the drawings showing examples.
FIG. 1A is a schematic plan view of an embodiment of an ice making vehicle according to the present invention, and FIG. 1B is a schematic side view. In FIG. 1 (a), the inside of the cooling cabinet mounted on the platform of the ice making vehicle is removed to show the inside.

製氷車1は、貯氷施設内の氷が融解した水を人工的に再凍結させるために使用される。製氷車1は、運搬車両11の荷台11A上に冷凍設備を搭載したものである。運搬車両11は、トラックなどの一般貨物自動車でよい。冷凍設備は、断熱された内部空間を有する冷却庫12と、室内機13及び室外機14から構成される冷凍機とを備えている。冷凍機に対して電源を供給するための発電機15も、荷台11A上に搭載している。冷却庫12は、コスト低減のために規格化して量産することが好ましい。   The ice making machine 1 is used to artificially refreeze water in which ice in the ice storage facility is melted. The ice making vehicle 1 has a refrigeration facility mounted on a loading platform 11 </ b> A of the transport vehicle 11. The transport vehicle 11 may be a general truck such as a truck. The refrigeration equipment includes a refrigerator 12 having an insulated internal space, and a refrigerator composed of an indoor unit 13 and an outdoor unit 14. A generator 15 for supplying power to the refrigerator is also mounted on the loading platform 11A. The refrigerator 12 is preferably standardized and mass-produced for cost reduction.

図1(a)では、冷却庫12の天井を取り除いた内部を概略的に示している。冷却庫112は、略直方体の筐体12Aに囲まれた密閉可能な内部空間を有する。筐体12Aの内面に断熱材12Bの層を設けることにより、内部空間の断熱性を確保している。冷却庫12には、メンテナンス作業のために少なくとも1箇所の出入り口が設けられ、開閉可能な扉12Cが取り付けられている。冷凍機の稼働時には扉12Cは閉じられる。   FIG. 1A schematically shows the inside of the refrigerator 12 with the ceiling removed. The refrigerator 112 has a sealable internal space surrounded by a substantially rectangular parallelepiped housing 12A. By providing a layer of the heat insulating material 12B on the inner surface of the housing 12A, the heat insulating property of the internal space is ensured. The refrigerator 12 is provided with at least one doorway for maintenance work, and a door 12C that can be opened and closed is attached. The door 12C is closed when the refrigerator is in operation.

冷却庫12の内部には、冷凍機の室内機14が設置されており、冷却庫12の外部には冷凍機の室外機13が設置されている。冷凍機は、稼働状態を制御するためのコントローラー(図示省略)も備えている。発電機15により冷凍機を稼働することにより、室内機14から冷却庫12の内部空間に冷気が送出される。冷凍機の冷凍能力は、製氷車1の適用対象となる貯氷施設の規模に合わせて選択する。冷却庫12の内部空間の大きさは、室内機14を設置して十分に稼働させられる程度であればよい。   A refrigerator indoor unit 14 is installed inside the refrigerator 12, and a refrigerator outdoor unit 13 is installed outside the refrigerator 12. The refrigerator also includes a controller (not shown) for controlling the operating state. By operating the refrigerator with the generator 15, cold air is sent from the indoor unit 14 to the internal space of the refrigerator 12. The refrigeration capacity of the refrigerator is selected according to the scale of the ice storage facility to which the ice making vehicle 1 is applied. The size of the internal space of the refrigerator 12 should just be a grade which can install and operate the indoor unit 14 enough.

さらに図1(b)に示すように、冷却庫12には、内部と外部を連通させる入気口12Dと排気口12Eが形成されている。稼働時には、入気口12D及び排気口12Eの各々に管状の連結手段の一端が着脱可能に連結される。管状の連結手段の他端は貯氷施設に連結される。管状の連結手段を通して冷却庫12と貯氷施設との間でエアを循環させる。管状の連結手段は、例えばフレキシブルダクト等のように可撓性を備えたものとする。それにより、冷却庫12と貯氷施設の連結位置の高さが完全に一致しておらず、また、冷却庫12と貯氷施設の間の距離が一定でなくとも対応可能である。製氷車1を使用しないときは、入気口12Dと排気口12Eを覆う適宜の蓋を取り付けることが好ましい。エアを強制的に循環させるために、エアを取り入れる入気口12Dには入気ファン16が、エアを送出する排気口12Eには排気ファン17が取り付けられている。入気ファン16及び排気ファン17の電源も発電機15から供給される。入気口12Dと排気口12Eは、図示の例では、冷却庫12の側面に上下方向に並べて形成しているが、この位置に限られない。   Furthermore, as shown in FIG.1 (b), the inlet 12D and the exhaust port 12E which connect the inside and the exterior are formed in the refrigerator 12. FIG. During operation, one end of a tubular connecting means is detachably connected to each of the inlet 12D and the outlet 12E. The other end of the tubular connecting means is connected to an ice storage facility. Air is circulated between the refrigerator 12 and the ice storage facility through a tubular connecting means. The tubular connecting means is provided with flexibility such as a flexible duct. As a result, the heights of the connecting positions of the refrigerator 12 and the ice storage facility do not completely coincide with each other, and the distance between the refrigerator 12 and the ice storage facility is not constant. When the ice making wheel 1 is not used, it is preferable to attach an appropriate lid that covers the inlet 12D and the outlet 12E. In order to forcibly circulate air, an inlet fan 16 is attached to the inlet 12D for taking in air, and an exhaust fan 17 is attached to the outlet 12E for sending out air. Power for the intake fan 16 and the exhaust fan 17 is also supplied from the generator 15. In the example shown in the drawing, the inlet 12D and the outlet 12E are formed side by side on the side surface of the refrigerator 12, but are not limited to this position.

FIG.

貯氷施設2は、青果物等を貯蔵するための移動式氷室の一例である。なお、作業用の出入り口等の図示は省略している。貯氷施設2の構造は、例えば、全体が外壁部材21で囲まれ、外壁部材21の内面に断熱材22の層を設けて内部の断熱性を確保している。内部には貯氷室23と貯蔵室24の2室が隔壁により区画され設けられている。貯氷室23内に収容された多数のタンク25は、水平面内にて縦横方向に並べられかつ上下方向に複数段積み重ねられている。これらのタンク25には凍結用の水が充填される。   The ice storage facility 2 is an example of a mobile ice room for storing fruits and vegetables. In addition, illustration of the doorway for work etc. is abbreviate | omitted. The structure of the ice storage facility 2 is, for example, entirely surrounded by an outer wall member 21, and a layer of a heat insulating material 22 is provided on the inner surface of the outer wall member 21 to ensure internal heat insulation. Two chambers, an ice storage chamber 23 and a storage chamber 24, are partitioned and provided by a partition. A large number of tanks 25 accommodated in the ice storage chamber 23 are arranged vertically and horizontally in a horizontal plane and stacked in a plurality of stages in the vertical direction. These tanks 25 are filled with water for freezing.

貯氷室23には、冬季(ここでは氷を自然凍結させる時期を指す)に外部からエアを取り込むために貯氷室入気ダンパー27を設けた貯氷室入気口23Dと、外部にエアを送出するために貯氷室排気ダンパー26を設けた貯氷室排気口23Cが形成されている。冬季には、黒矢印の一点鎖線のように自然の寒冷エアが貯氷室23内を流れることにより、タンク25内の水が凍結する。   The ice storage chamber 23 is supplied with an ice storage chamber inlet 23D provided with an ice storage chamber intake damper 27 in order to take in air from the outside in winter (here, it indicates the time when ice is naturally frozen), and air is sent to the outside. Therefore, an ice storage chamber exhaust port 23C provided with an ice storage chamber exhaust damper 26 is formed. In the winter season, natural cold air flows in the ice storage chamber 23 as indicated by the alternate long and short dash line of the black arrow, so that the water in the tank 25 is frozen.

また、貯氷室23と貯蔵室24の隔壁には、夏季(ここでは氷を自然凍結させる冬季以外の時期であって貯氷室の氷を利用する時期を指す)において貯氷室23から貯蔵室24にエアを送出するために貯蔵室入気ダンパー29を設けた貯蔵室排気口23Fと、貯蔵室24から貯氷室23にエアを戻すために貯蔵室排気ダンパー28を設けた貯蔵室排気口23Eが形成されている。夏季には、白矢印の一点鎖線のように貯氷室23から送出された冷却エアが貯蔵室24内を流れ、貯氷室23に戻る。貯蔵室24には、青果物等を貯蔵する。   In addition, the partition walls of the ice storage chamber 23 and the storage chamber 24 are connected from the ice storage chamber 23 to the storage chamber 24 in the summer (here, the time is other than the winter season when the ice is naturally frozen and the ice in the ice storage chamber is used). A storage chamber exhaust port 23F provided with a storage chamber inlet damper 29 for delivering air and a storage chamber exhaust port 23E provided with a storage chamber exhaust damper 28 for returning air from the storage chamber 24 to the ice storage chamber 23 are formed. Has been. In summer, the cooling air sent from the ice storage chamber 23 flows in the storage chamber 24 as indicated by the alternate long and short dash line of the white arrow and returns to the ice storage chamber 23. The storage room 24 stores fruits and vegetables.

貯氷室23にはさらに、外部に面した側壁に、図1に示した製氷車と連結するための製氷車用排気口23A及び製氷車用入気口23Bが形成されている。製氷車用排気口23A及び製氷車用入気口23Bは、使用しないときは適宜の蓋で覆うことが好ましい。   The ice storage chamber 23 is further formed with an ice making vehicle exhaust port 23A and an ice making air intake port 23B for connecting to the ice making vehicle shown in FIG. The ice making vehicle exhaust port 23A and the ice making air intake port 23B are preferably covered with appropriate lids when not in use.

なお、図2に示した貯氷施設2は一例であり、本発明は多様な構成の貯氷施設に適用可能である。特に、貯氷量20トン〜100トンの小型、中型のアイスシェルターに図1のの製氷車を組み合わせることが好適である。特許文献1に記載した設置型のアイスシェルターにも適用可能である。移動式氷室とした場合は、貯氷施設も製氷車もともに移動可能であるので、広範な利用形態が可能となる。また、既存の貯氷施設の場合、製氷車用排気口23A及び製氷車用入気口23Bを新たに形成することで、本発明の製氷車を利用可能となる。   The ice storage facility 2 shown in FIG. 2 is an example, and the present invention can be applied to ice storage facilities having various configurations. In particular, it is preferable to combine the ice making vehicle of FIG. 1 with a small and medium-sized ice shelter having an ice storage amount of 20 to 100 tons. The present invention can also be applied to the installation type ice shelter described in Patent Document 1. In the case of a mobile ice room, both the ice storage facility and the ice making vehicle can move, so a wide variety of usage forms are possible. In the case of an existing ice storage facility, the ice making vehicle of the present invention can be used by newly forming the ice making vehicle exhaust port 23A and the ice making air intake port 23B.

図3(a)は、図1に示した製氷車を図2に示した貯氷施設に連結した状態を示す概略平断面図であり、(b)は概略側断面図である。   3A is a schematic plan sectional view showing a state where the ice making vehicle shown in FIG. 1 is connected to the ice storage facility shown in FIG. 2, and FIG. 3B is a schematic side sectional view.

夏季には、貯氷室23のタンク25内の氷が次第に融解する。例えば、貯蔵室24の温度が所定の温度よりも上昇するなど、貯氷室23の冷却機能の低下が検知されたとき、製氷車1を貯氷施設2まで運転してきて、貯氷施設2の側壁に沿って駐車させる。   In summer, the ice in the tank 25 of the ice storage chamber 23 is gradually melted. For example, when a decrease in the cooling function of the ice storage chamber 23 is detected, such as when the temperature of the storage chamber 24 rises above a predetermined temperature, the ice making vehicle 1 is driven to the ice storage facility 2 and along the side wall of the ice storage facility 2.

続いて、製氷車1の冷却庫12に形成した入気口12Dと、貯氷施設2の貯氷室23に形成した製氷車用排気口23Aを、フレキシブルダクト等の管状の連結手段31により連結する。また、製氷車1の冷却庫12に形成した排気口12Eと、貯氷施設2の貯氷室23に形成した製氷車用入気口23Bを、フレキシブルダクト等の管状の連結手段32により連結する。入気口12Dと製氷車用排気口23Aがほぼ同じ高さに位置し、排気口12Eと製氷車用入気口23Bがほぼ同じ高さに位置することが、エアを円滑に循環させるために好ましい。しかし、フレキシブルダクトのような柔軟性のある管を用いるので、双方の高さが異なっていてもよい。   Subsequently, the air inlet 12D formed in the refrigerator 12 of the ice making vehicle 1 and the ice making vehicle exhaust port 23A formed in the ice storage chamber 23 of the ice storage facility 2 are connected by a tubular connecting means 31 such as a flexible duct. Further, the exhaust port 12E formed in the refrigerator 12 of the ice making vehicle 1 and the ice making air inlet 23B formed in the ice storage chamber 23 of the ice storage facility 2 are connected by a tubular connecting means 32 such as a flexible duct. In order to smoothly circulate the air, the inlet 12D and the ice making exhaust 23A are located at substantially the same height, and the exhaust 12E and the ice making inlet 23B are located at substantially the same height. preferable. However, since a flexible pipe such as a flexible duct is used, the heights of both may be different.

その後、製氷車1の冷凍機を稼働させると、黒矢印の一点鎖線で示すように、冷却庫12と貯氷室23の間でエアが循環する。これにより、タンク25内の氷が融解した水が再凍結する。このとき、貯氷室23の貯氷室排気ダンパー26、貯氷室入気ダンパー27、貯蔵室排気ダンパー28及び貯蔵室入気ダンパー29は、全て閉じておく。再凍結が完了したならば、管状の連結手段31、32を取り外して製氷車1を切り離す。   Thereafter, when the refrigerator of the ice making machine 1 is operated, air circulates between the cooler 12 and the ice storage chamber 23 as indicated by the one-dot chain line of the black arrow. Thereby, the water in which the ice in the tank 25 is melted is frozen again. At this time, the ice storage chamber exhaust damper 26, the ice storage chamber intake damper 27, the storage chamber exhaust damper 28, and the storage chamber intake damper 29 of the ice storage chamber 23 are all closed. When the refreezing is completed, the tubular connecting means 31 and 32 are removed and the ice making wheel 1 is separated.
