で至っている。(Problems to be solved by the invention) By the way, the ice cubes manufactured by the conventional ice-making machine have a rectangular parallelepiped shape and a uniform shape, and it is easy to give a frivolous feeling because it is obvious that the machine is mass-produced. Therefore, there is a limit to its spread, and there is a demand in the art for the emergence of a device that can mechanically and mass-produce an ice block of the same shape as the cracked ice that was conventionally made by hand. Originally, it is irregular and not one of them has the same shape, whereas an automatic ice machine is basically impossible because it has a structure that obtains ice in a uniform shape. To the present.

The water sprinkler is characterized by having a unique structure, and the aim is to improve the image by giving the same profound feeling as that obtained by hand.

たものである。(Means for Solving the Problems) However, as is clear from the examples shown in the accompanying drawings, the present invention comprises a plurality of concave portions (13) having tapered conical surfaces such as conical surfaces and pyramidal surfaces, An ice making plate (11) in which (13) are dispersed and recessed on the same side is provided so that the recesses (13) and (13) project downward, and the recesses (13) and (1)
While the cooling pipes (4) are respectively installed in the inside of 3), a water sprinkler (12) that can evenly disperse water on the outer peripheral wall of the recess (13) is surrounded by the recesses (13) and (13). It is what constitutes an ice machine.

って夫々異なってくる。(Working) Sprinkler (12) on the ice-making surface of the concave portion (13) forming a downward conical surface
If you apply water with, the amount of water sprinkled will inevitably become uneven,
Moreover, since the dynamics flowing down along the conical surface also change, the shape and layer thickness of the frozen portion along the conical surface become indefinite, and they differ from position to position.

氷に近似した外形となる。Furthermore, once the irregular morphology occurs, the ice thickens along the lower surface of the irregularly flowing water flow, so that the ice gathers in thick places and the water flows to the lower side, and as a result, it becomes thick in the mountain range. As a result, a change occurs in a thin place, and thus the ice block that has separated from the recess (13) has an irregular shape and an outer shape similar to that of smashing ice.

この氷塊は、円錐，角錐等の錐体を核としながら外形は
製氷の都度異なり不定であるので不規則な形の氷塊が得
られる。This ice block has cones such as cones and pyramids as cores, but the outer shape is different each time ice is made and is indefinite, so an ice block having an irregular shape can be obtained.
