ものである。(Conventional technology) Many ice makers that continuously produce ice cubes used in coffee shops, restaurants, etc. are of the open-cell type, in which ice-making water is fed from below into a large number of ice-making chambers that open downward. , for example, is known from Japanese Utility Model Application Publication No. 59-174580, etc., and this is a form in which a water sprinkler device having a structure in which a paddle rotates around a horizontal axis while appearing and disappearing on the water surface is installed in a water storage tank for raw water.

坦面が得難く、かつ製氷効率が悪い等の問題があった。(Problem to be solved by the invention) When raw water is continuously injected into each ice-making chamber in this way, the areas where the water hits are constantly under water pressure, and there is a problem in forming a thin layer of ice. There were problems such as the exposed center of the ice cube becoming depressed due to the high temperature water being sprayed against the object, making it difficult to obtain a flat surface and poor ice making efficiency.

Ice maker Q3) in the shape of a cubic grid with the ice making surface facing downwards
In an ice making machine that circulates water in an ice making water tank (8) to the ice making surface of the ice making surface and freezes the ice making water on the ice making surface that is cooled by an evaporator, the hollow arm is vertically rotatable in a horizontal plane. A rotary injection nozzle (1) supported on one axis α and connected to an ice-making water supply line is disposed below the ice maker, and the injection nozzle α is connected to the hollow arm. The injection nozzle (1) is diffused in a fan shape in the longitudinal direction of the arm at positions on both sides asymmetrical with respect to the center of rotation, and is opened in a slit shape so that a part of the diffused water can intersect with the ice making surface. a predetermined number of rotations, preferably 2
It is characterized in that it rotates at a rotational speed within the range of 0 to 120 times/minute.

中央に凹みが生じ難く、かつ氷層内に巣も発生しない。(Function) The water sprayed from the rotary spray nozzle (1) hits each ice-making surface that produces ice cubes not continuously but intermittently, so that during a predetermined period of around 1 second when water does not hit the ice cubes, The water adhering to the ice-making surface is rapidly cooled to form an ice film, and since no water pressure is applied, the bottom surface is flat, making it difficult to form a dent in the center and preventing the formation of cavities within the ice layer.

て、形の整った直方体の角氷が製造される。The rotary injection nozzle (1) has an asymmetrical fountain position, spreads in a fan shape, and some of the water flows intersect on the ice-making surface, so that, together with the equalization effect due to rotation, the ice-making process is improved. Well-shaped rectangular parallelepiped ice cubes are produced without creating blind areas as shown by cross hatching in FIG. 3 in the front and rear spaces in contact with the vertical ice-making partitions.

領域は全然存しなく、その結果、各立方格子内には同厚
の氷が形成されて行く。(14) is placed at a different position with respect to each ice-making cubic grid and the water spray angle is different, so there is no blind area where water does not hit, and as a result, each cubic grid has the same thickness. Ice is forming.

置換される結果、この保有熱量で離氷が成される。When ice (cube) of a certain thickness is made, the water level in the ice making water tank (8) drops and the float switch αΦ
sends a low water level signal, ice making is completed and the solenoid valve (
4) is opened and the pre-cooled water in the upper water tank (2) is replaced with room temperature water, and as a result, ice is removed using this retained heat amount.
離氷運転はこの他に給水を製氷水タンク（８）に貯めて
今一つのポンプ（図示せず）により上部水タンク（２）
に循環させるようにしても良い。In addition to this operation, water is stored in the ice-making water tank (8) and pumped to the upper water tank (2) using another pump (not shown).
It is also possible to circulate it.

外気低水温時とではデフロスト時間に差があって氷が溶
けてしまうことが起こり得るからであり、むしろ補助的
に利用することが好ましいといえる。The reason why the hot gas defrost method is not used for ice removal is that with this method, the ice melts due to the difference in defrost time between when the outside air and water temperature is high, such as in the summer, and when the outside air and water temperature is low, such as in the winter. This is because such things can happen, so it can be said that it is preferable to use it in an auxiliary manner.

方式の欠点を解消し得て効率良く、しかも下面が平坦な
氷を製造することが可能である。Therefore, the injection nozzle (1) rotates while the injection nozzle Q
Since the water is injected from 41, the ice-making water is not continuously but intermittently injected onto each cubic lattice, which eliminates the disadvantage of the continuous method of raising the temperature of water that is about to freeze on the surface and washing it away. It is possible to efficiently produce ice with a flat bottom surface.
このことは角氷の下面が全部つながるよりも早く製氷を

きて、口詰まりに強い構造となる。This leads to the advantage that ice making can be stopped before the bottom surfaces of the ice cubes are all connected, and that well-shaped ice cubes can be reliably taken out in a separated state.
Two injection ports Q4) are sufficient for water supply to 30 cubic grids, and the nozzle diameter can be increased accordingly, resulting in a structure that is resistant to clogging.
なお、製氷量が多くなれば噴射ノズル（１）の長さ、噴
射口α旬の数又は噴射拡散角度を大きくすれば良く、対
応が容易かつ簡単である。Incidentally, if the amount of ice to be made increases, the length of the injection nozzle (1), the number of injection ports α, or the injection diffusion angle may be increased, which is easy and simple.
また、前記ノズル（１）の回転速度は２０〜１２０回／
分の範囲内が好適であって、５０回／分が製氷速度を向

度であることが実験的に解明されている。Further, the rotation speed of the nozzle (1) is 20 to 120 times/
It has been experimentally determined that a rotation speed of 50 times/minute is suitable for obtaining appropriate timing to improve the ice making speed.
なお、前記ノズル（１）を自転形とするためには、前記
噴射口Ｑ４）以外に別途専用の噴水口を形成するように
しも良い。In addition, in order to make the nozzle (1) of an autorotating type, a dedicated water fountain may be formed separately in addition to the jet nozzle Q4).

領域を生ぜしめず平均に噴射可能であり、従って同等の
大きさ、速さの角氷を一斉に製造し得る。In the ice making machine according to claim 1, the injection port (14) is located at a non-protection position with respect to the center of rotation, and two types of water streams with different injection angles can be injected into each cubic grid, so that there is no blind spot where water does not hit. It is possible to spray ice cubes evenly without creating an area, so ice cubes of the same size and speed can be produced all at once.

く製氷できる。Furthermore, since it is a method that sprays intermittently rather than continuously, it is possible to lower the temperature of the growing ice surface and quickly create a frozen layer, so there is no denting caused by constant application of water pressure. Combined with this, ice cubes with a flat surface can be made efficiently.
請求項２の製氷機においては、特に噴射ノズル（１）の
