Description

この発明は、ドラム式製氷機に係り、特に製氷水タンク内の製氷水を散水パイプによりドラムに散水するドラム式製氷機に関する。   The present invention relates to a drum type ice making machine, and more particularly to a drum type ice making machine that sprays ice making water in an ice making water tank onto a drum by a water spray pipe.

特許文献１には、製氷水と円筒ドラム内を流通する冷媒との間で熱交換を行わせることによって、製氷水を円筒ドラムの表面に着氷させるドラム式製氷機が記載されている。
一般的なドラム式製氷機について図３を用いて説明する。ドラム式製氷機５０１は、氷を作るための水である製氷水が満たされる製氷水タンク５０２と、冷凍回路における蒸発器を内部に有する円筒ドラム５０３とを備えている。製氷水タンク５０２内には、製氷水を吸引するためのポンプモータ５０４の吸引口５０４ａが設けられ、ここから吸引された製氷水は、ホース５０５を経由して、製氷水散水手段である散水パイプ５０６から円筒ドラム５０３上に散水される。また、フロートスイッチ５０８により製氷水タンク５０２内の水位が下がったことが検出されると、給水バルブ５０７の吐出口５０７ａから冷却されていない製氷水が補給される。そして、円筒ドラム５０３が回転駆動されると共に冷却されると、散水パイプ５０６から散水された製氷水と製氷水タンク５０２内の製氷水は円筒ドラム５０３によって冷却され、円筒ドラム５０３の表面には層状の氷が成長する。この氷層は、カッタ５０９により剥離されて図示しない貯氷庫に蓄えられる。 Patent Document 1 describes a drum type ice making machine that causes ice making water to adhere to the surface of a cylindrical drum by performing heat exchange between ice making water and a refrigerant circulating in the cylindrical drum.
A general drum type ice making machine will be described with reference to FIG. The drum type ice making machine 501 includes an ice making water tank 502 filled with ice making water, which is water for making ice, and a cylindrical drum 503 having an evaporator in the refrigeration circuit. The ice making water tank 502 is provided with a suction port 504a of a pump motor 504 for sucking ice making water, and the ice making water sucked from here is supplied through a hose 505 to a sprinkling pipe as ice making water sprinkling means. Water is sprinkled from 506 onto the cylindrical drum 503. Further, when the float switch 508 detects that the water level in the ice making water tank 502 has dropped, uncooled ice making water is supplied from the discharge port 507a of the water supply valve 507. When the cylindrical drum 503 is rotated and cooled, the ice making water sprayed from the water sprinkling pipe 506 and the ice making water in the ice making water tank 502 are cooled by the cylindrical drum 503, and the surface of the cylindrical drum 503 is layered. Ice grows. This ice layer is peeled off by the cutter 509 and stored in an ice storage (not shown).

特開平８−２９０３２号公報JP-A-8-29032

しかしながら、図３に示されるようなドラム式製氷機５０１では、給水バルブ５０７の吐出口５０７ａの直下にポンプモータ５０４の吸引口５０４ａが設けられている。そのため、給水バルブ５０７の吐出口５０７ａから供給された冷却されていない製氷水は、十分に冷却されないまま図３において黒矢印で示されるように流れ、ポンプモータ５０４の吸引口５０４ａから吸引されてしまう。その結果、散水パイプ５０６からは十分に冷却されていない製氷水が円筒ドラム５０３上に散水され、円筒ドラム５０３の表面に成長する氷層の質と量が不安定になる。すなわち、安定した氷質と製氷量を得ることができない。   However, in the drum type ice making machine 501 as shown in FIG. 3, the suction port 504 a of the pump motor 504 is provided immediately below the discharge port 507 a of the water supply valve 507. Therefore, the uncooled ice-making water supplied from the discharge port 507a of the water supply valve 507 flows as indicated by the black arrow in FIG. 3 without being sufficiently cooled, and is sucked from the suction port 504a of the pump motor 504. . As a result, ice making water that has not been sufficiently cooled is sprinkled from the sprinkling pipe 506 onto the cylindrical drum 503, and the quality and quantity of the ice layer that grows on the surface of the cylindrical drum 503 becomes unstable. That is, a stable ice quality and ice making amount cannot be obtained.

この発明はこのような問題点を解決するためになされたものであり、製氷水散水手段から散水される製氷水の温度を常に低く保ち、安定した氷質と製氷量を得ることができるドラム式製氷機を提供することを目的とする。   The present invention has been made to solve such problems, and is a drum type capable of constantly maintaining the temperature of ice making water sprayed from the ice making water sprinkling means to obtain a stable ice quality and ice making amount. An object is to provide an ice making machine.

上記の課題を解決するために、この発明に係るドラム式製氷機は、製氷水が満たされるタンクと、タンク内において回転駆動されると共に冷却されるドラムと、ドラムに製氷水を散水する製氷水散水手段と、タンク内の製氷水を吸引して製氷水散水手段に送る製氷水吸引手段と、タンク内に製氷水を供給する製氷水供給手段とを備えるドラム式製氷機において、製氷水供給手段の吐出口は、ドラムの回転軸を挟んで製氷水吸引手段の吸引口の反対側の領域に設けられる。
これにより、製氷水散水手段から散水される製氷水の温度が常に低く保たれ、安定した氷質と製氷量を得ることができる。 In order to solve the above-described problems, a drum type ice making machine according to the present invention includes a tank filled with ice making water, a drum that is rotated and cooled in the tank, and ice making water that sprays ice making water onto the drum. In a drum-type ice making machine comprising water sprinkling means, ice making water suction means for sucking ice making water in the tank and sending it to the ice making water sprinkling means, and ice making water supply means for supplying ice making water into the tank, ice making water supply means The discharge port is provided in a region opposite to the suction port of the ice making water suction unit across the rotating shaft of the drum.
Thereby, the temperature of the ice making water sprayed from the ice making water sprinkling means is always kept low, and a stable ice quality and ice making amount can be obtained.

製氷水散水手段は、ドラムの回転軸を挟んで製氷水吸引手段の吸引口の反対側の領域に設けられてもよい。
これにより、タンク内の特定箇所に冷水が滞留することがなく、タンク内の機能部品を氷結させてしまうことがない。 The ice making water sprinkling means may be provided in a region on the opposite side of the suction port of the ice making water suction means across the rotating shaft of the drum.
Thereby, cold water does not stay in a specific location in the tank, and the functional components in the tank are not frozen.

この発明の実施の形態に係るドラム式製氷機の模式断面図を図１に示す。
ドラム式製氷機１は、氷を作るための水である製氷水が満たされる製氷水タンク２と、製氷水タンク２内に設けられると共に図示しない冷凍回路における蒸発器を内部に有する円筒ドラム３とを備えている。円筒ドラム３は、図示しないギヤモータによって回転軸Ｏを中心に回転駆動されると共に、蒸発器内を流通する冷媒によって冷却される。すなわち、ドラム式製氷機１は、製氷水と円筒ドラム３内を流通する冷媒との間で熱交換を行わせることによって、製氷水を円筒ドラム３の表面に着氷させるものである。 Embodiments of the present invention will be described below with reference to the accompanying drawings.
A schematic cross-sectional view of a drum type ice making machine according to an embodiment of the present invention is shown in FIG.
The drum type ice making machine 1 includes an ice making water tank 2 filled with ice making water, which is water for making ice, and a cylindrical drum 3 provided in the ice making water tank 2 and having an evaporator in a refrigeration circuit (not shown) inside. It has. The cylindrical drum 3 is driven to rotate about a rotation axis O by a gear motor (not shown) and is cooled by a refrigerant flowing through the evaporator. That is, the drum type ice making machine 1 causes the ice making water to adhere to the surface of the cylindrical drum 3 by performing heat exchange between the ice making water and the refrigerant circulating in the cylindrical drum 3.

製氷水タンク２内において、円筒ドラム３の回転軸Ｏを挟んで右側の領域（図１における点線Ｐの右側の領域）の壁面には、製氷水タンク２内の製氷水を吸引するためのポンプモータ４の吸引口４ａが設けられている。ポンプモータ４の吐出口４ｂは、ホース５を介して、製氷水を円筒ドラム３上に散水するための散水パイプ６に接続されている。ここで、散水パイプ６は、円筒ドラム３の上方且つ回転軸Ｏを挟んでポンプモータ４の吸引口４ａの反対側の領域（図１における点線Ｐの左側の領域）に設けられている。詳細には、製氷水タンク２の上蓋には、図１における紙面奥方向に向けて複数の保持部２ａが設けられており、散水パイプ６は、これら保持部２ａに形成された通孔に通されて固定されている。
また、製氷水タンク２内において、円筒ドラム３の回転軸Ｏを挟んでポンプモータ４の吸引口４ａの反対側の領域（図１おける点線Ｐの左側の領域）には、製氷水タンク２内に製氷水を供給するための給水バルブ７の吐出口７ａが設けられており、給水バルブ７は図示しない外部水道系に接続されている。
さらに、ポンプモータ４の吸引口４ａの上方には、製氷水タンク２内の水位を検出するためのフロートスイッチ８が設けられており、そのさらに上方には、円筒ドラム３の表面に成長した氷層を剥離するためのカッタ９が設けられている。 In the ice making water tank 2, a pump for sucking the ice making water in the ice making water tank 2 is placed on the wall surface of the right side (the right side of the dotted line P in FIG. 1) across the rotation axis O of the cylindrical drum 3. A suction port 4a of the motor 4 is provided. The discharge port 4 b of the pump motor 4 is connected via a hose 5 to a watering pipe 6 for spraying ice-making water onto the cylindrical drum 3. Here, the water sprinkling pipe 6 is provided above the cylindrical drum 3 and in a region on the opposite side of the suction port 4a of the pump motor 4 across the rotation shaft O (region on the left side of the dotted line P in FIG. 1). Specifically, the upper lid of the ice making water tank 2 is provided with a plurality of holding portions 2a toward the back of the sheet in FIG. 1, and the water sprinkling pipe 6 passes through the through holes formed in these holding portions 2a. Has been fixed.
Further, in the ice making water tank 2, an area on the opposite side of the suction port 4 a of the pump motor 4 across the rotation axis O of the cylindrical drum 3 (the area on the left side of the dotted line P in FIG. 1) A discharge port 7a of a water supply valve 7 for supplying ice-making water is provided, and the water supply valve 7 is connected to an external water system (not shown).
Further, a float switch 8 for detecting the water level in the ice making water tank 2 is provided above the suction port 4 a of the pump motor 4, and further above the ice grown on the surface of the cylindrical drum 3. A cutter 9 for separating the layers is provided.

次に、この実施の形態に係るドラム式製氷機の動作について説明する。
ドラム式製氷機１が製氷動作を開始すると、円筒ドラム３は、ギヤモータによって回転駆動されると共に、蒸発器内を流通する冷媒によって冷却される。また、製氷水タンク２内の製氷水の一部がポンプモータ４の吸引口４ａから吸引されて散水パイプ６に送られ、散水パイプ６から円筒ドラム３上に散水される。 Next, the operation of the drum type ice making machine according to this embodiment will be described.
When the drum type ice making machine 1 starts the ice making operation, the cylindrical drum 3 is driven to rotate by the gear motor and is cooled by the refrigerant flowing through the evaporator. Further, a part of the ice making water in the ice making water tank 2 is sucked from the suction port 4 a of the pump motor 4 and sent to the sprinkling pipe 6 and sprinkled on the cylindrical drum 3 from the sprinkling pipe 6.

また、フロートスイッチ８により製氷水タンク２内の水位が所定値より下がったことが検出されると、給水バルブ７の吐出口７ａから冷却されていない製氷水が供給される。ここで、この冷却されていない製氷水は、図１において黒矢印で示される方向に流れる過程で円筒ドラム３内を流通する冷媒と熱交換することによって冷却されるため、ポンプモータ４の吸引口４ａ付近の製氷水の温度は常に低く保たれる。その結果、散水パイプ６から散水される製氷水の温度も常に低く保たれる。   Further, when the float switch 8 detects that the water level in the ice making water tank 2 has dropped below a predetermined value, uncooled ice making water is supplied from the discharge port 7a of the water supply valve 7. Here, the uncooled ice-making water is cooled by exchanging heat with the refrigerant circulating in the cylindrical drum 3 in the process of flowing in the direction indicated by the black arrow in FIG. The temperature of ice-making water near 4a is always kept low. As a result, the temperature of the ice making water sprayed from the sprinkling pipe 6 is always kept low.

このような状態において、散水パイプ６から散水された製氷水と製氷水タンク２内の製氷水は円筒ドラム３内を流通する冷媒と熱交換することによって冷却され、円筒ドラム３の表面には質と量が共に安定した層状の氷が成長する。そして、円筒ドラム３の回転に伴って水面上の製氷水が降り注がない位置に移動した氷層は、過冷却されて水分を含まない乾いた氷になり、カッタ９により剥離されて図示しない貯氷庫に蓄えられる。   In such a state, the ice making water sprinkled from the water sprinkling pipe 6 and the ice making water in the ice making water tank 2 are cooled by exchanging heat with the refrigerant circulating in the cylindrical drum 3, and the surface of the cylindrical drum 3 has a quality. A layered ice with a stable amount grows. Then, the ice layer that has moved to a position where the ice-making water on the surface of the water is not poured with the rotation of the cylindrical drum 3 becomes dry ice that does not contain water and is supercooled, and is peeled off by the cutter 9 and is not shown. Stored in an ice storage.

以上説明したように、この実施の形態に係るドラム式製氷機１では、給水バルブ７の吐出口７ａは、円筒ドラム３の回転軸Ｏを挟んでポンプモータ４の吸引口４ａの反対側の領域に設けられている。これにより、散水パイプ６から散水される製氷水の温度は常に低く保たれ、安定した氷質と製氷量を得ることができる。   As described above, in the drum ice making machine 1 according to this embodiment, the discharge port 7a of the water supply valve 7 is a region on the opposite side of the suction port 4a of the pump motor 4 across the rotation axis O of the cylindrical drum 3. Is provided. Thereby, the temperature of the ice making water sprayed from the sprinkling pipe 6 is always kept low, and a stable ice quality and ice making amount can be obtained.

また、図３に示される従来技術に係るドラム式製氷機５０１では、ポンプモータ５０４の吸引口５０４ａから近い位置に散水パイプ５０６が設けられているため、散水パイプ５０６から散水された製氷水は、図３において白丸で示される方向に流れて吸引口５０４ａから吸引されてしまう。そのため、フロートスイッチ５０８の付近に冷水が滞留してしまい、フロートスイッチ５０８等の製氷水タンク５０２内の機能部品を氷結させてしまうおそれがある。これに対して、この実施の形態に係るドラム式製氷機１では、散水パイプ６は、円筒ドラム３の回転軸Ｏを挟んでポンプモータ４の吸引口４ａの反対側の領域に設けられている。すなわち、散水パイプ６はポンプモータ４の吸引口４ａから遠い位置に設けられている。そのため、散水パイプ６から散水された製氷水は、図１において白丸で示される方向に流れて製氷水タンク２内を循環する。これにより、製氷水タンク２内の特定箇所に冷水が滞留することがなく、フロートスイッチ８等の製氷水タンク２内の機能部品を氷結させてしまうことがない。   Further, in the drum type ice making machine 501 according to the prior art shown in FIG. 3, since the water sprinkling pipe 506 is provided at a position near the suction port 504a of the pump motor 504, the ice making water sprinkled from the water sprinkling pipe 506 is In FIG. 3, it flows in the direction indicated by the white circle and is sucked from the suction port 504a. For this reason, cold water may stay in the vicinity of the float switch 508, and there is a possibility that the functional components in the ice making water tank 502 such as the float switch 508 may be frozen. On the other hand, in the drum type ice making machine 1 according to this embodiment, the water sprinkling pipe 6 is provided in a region opposite to the suction port 4a of the pump motor 4 with the rotating shaft O of the cylindrical drum 3 interposed therebetween. . That is, the sprinkling pipe 6 is provided at a position far from the suction port 4 a of the pump motor 4. Therefore, the ice making water sprinkled from the water sprinkling pipe 6 flows in the direction indicated by the white circle in FIG. 1 and circulates in the ice making water tank 2. Thereby, cold water does not stay in a specific location in the ice making water tank 2, and functional parts in the ice making water tank 2 such as the float switch 8 are not frozen.

尚、実施の形態において、円筒ドラム３の回転軸Ｏを挟んで左側の領域にポンプモータ４の吸引口４ａを設け、回転軸Ｏを挟んで右側の領域に給水バルブ７の吐出口７ａ及び散水パイプ６を設けてもよい。   In the embodiment, the suction port 4a of the pump motor 4 is provided in the left region across the rotation axis O of the cylindrical drum 3, and the discharge port 7a and the water spray of the water supply valve 7 are disposed in the right region across the rotation shaft O. A pipe 6 may be provided.

また、実施の形態に係るドラム式製氷機１において、散水パイプ６用の図２（ａ）〜（ｃ）に示すような第１〜第３の取り付け部材群を用いることによって、散水パイプ６の取り付け角度を調整してもよい。これにより、散水パイプ６から散水された製氷水が円筒ドラム３上に降り注ぐ面積を変えることができ、円筒ドラム３の表面に成長する氷層の質と量を調整することができる。図２（ａ）〜（ｃ）において、右側の図は、その左側の図を紙面裏側から見た図である。   Moreover, in the drum type ice making machine 1 which concerns on embodiment, by using the 1st-3rd attachment member group as shown to FIG. 2 (a)-(c) for the watering pipe 6, of the watering pipe 6 is used. The attachment angle may be adjusted.
