ものである。(Means for Solving the Problems) However, as will be apparent from the embodiments with reference to the present invention, a plurality of hemispherical metallic ice-making cups (14) are formed into a bowl shape which opens downward. The cooling pipes (4) are attached to the surface of the ice making cup (14) while being connected side by side by the substrate (16), and a hemispherical surface of the same shape as the ice making cup (14) is divided into 1/4 spherical surfaces by equal division. 1 ice cover (1
5) and (15) are closed to each other so that they can form a hemisphere surface and an ice making cup (14) can form a spherical surface, and a closed state that forms a hemisphere surface and an expanded state that opens by separation. The substrate (16) is pivotally supported so as to be swingable so that it can be opened.
Giving a spring force capable of holding the closed state during ice making,
Further, a hole (17) for water injection is cut at the lowest butting point in each ice making cover (15) (15), and water is directed toward the hole (17) to make an ice making cup (14). ) Is attached to the fountain device (10) to inject the water into the ice making machine.

強さにしたことを好ましい実施態様とするものである。Further, in the present invention, the spring force applied to the ice making covers (15) and (15) is counteracted by the total weight of the ice balls in the ice making cup (14) and the ice making covers (15) and (15) at the time of water separation. It is a preferred embodiment that the ice-making covers (15) and (15) are made strong enough to be opened without being obtained.

球は落下する。When ice balls with a predetermined shape are generated, the ice balls are switched to ice-breaking, but since the ice balls are separated from the ice-making cup (14) by the ice-breaking, the weight is added to the ice-making covers (15) and (15), and thus ice-making is performed. The ice balls fall to spread the ice making covers (15) and (15) by overcoming the spring force applied to the covers (17) and (17).
氷球の落下後、製氷カバー（15），（15）はバネ力によ
り閉成状態に復元する。After the ice balls fall, the ice making covers (15) and (15) are restored to the closed state by the spring force.

は言うまでもない。By the way, the spring force of the spring (18) is as shown in FIG.
The ice-making cover (15),
It is necessary not only to have the strength to prevent (15) from being opened, but also to set the strength to such an extent that the ice making cover (15) can be opened by the weight of the ice balls grown by ice-freezing. It goes without saying that there is.

い問題があるが、真球が得られ易い利点がある。On the other hand, the ice-making cover (15) may be either a mold made of synthetic resin or a metal squeezed product such as aluminum, but if it is made of synthetic resin, the ice-making efficiency at the cover portion, which is the lower half of the spherical surface, is poor and the ice-making cover is made. Time tends to be long, and second
Water-based deicing using the nozzle (13) also has a problem of low efficiency in the low water temperature region, but has the advantage of easily obtaining a true sphere.

大きくとることが好ましい。On the other hand, in the case of metal, the operation efficiency for ice making and ice removal is good, but if the hole (17) is made smaller, the hole (17) is closed first during the ice growth process and a cavity is formed in the spherical core. Therefore, it is preferable to make the hole (17) larger than that made of synthetic resin.
以上述べたように同重量当たりで表面積が最小の球形氷
