Abstract

PURPOSE: To make an ice block of substantially perfect sphere easily and surely by providing a hemispherical ice making cup and a set of two ice making covers. CONSTITUTION: A spherical face of small radius is formed through combination of spring charged ice making covers 15, 15, and an ice making cup 14. Cold water ejected by an ejector 10 from a lower hole 17 adheres to the inner surface of the cup 14 and the covers 15, 15 to form a thin layer which grows gradually to produce a spherical ice having solid deep layer. Since the spherical ice adheres the cup 14 tightly, the covers 15, 15 are held in closed state. When an ice ball of specified shape is formed, it is separated from the cup 14 and the weight thereof is applied to the covers 15, 15 which is thereby opened while prevailing over the spring force imparted thereto thus dropping the ice ball.

(Conventional technology) In places such as restaurants, cafeterias, coffee shops, and bars that require large amounts of small ice cubes to be used in cold drinks, so-called "cut ice" is made by crushing large ice cubes. Recently, there has been a tendency for ice makers to be used since they are extremely inefficient, and for example, there is a known ice making machine as disclosed in Japanese Utility Model Application Publication No. 17767/1983.

(Problems to be Solved by the Invention) By the way, all of the known conventional ice cubes produce rectangular parallelepiped ice cubes, and the ice used seems to be uniform. Although it has not become widespread,
The production of ice cubes in the shape of a rectangular parallelepiped was unavoidable due to the convenience of ice removal, and machines that can produce ice cubes of unusual shapes are still being proposed due to technical difficulties. The reality is that it has not been done.

On the other hand, regarding the ice making cover α, either a synthetic resin mold or a drawn metal such as aluminum may be used, but if it is made of synthetic resin, the ice making efficiency is poor in the part of the cover that is the lower half of the spherical surface. Although there is a problem that the time tends to be long, and the ice removal using water by the second nozzle a is inefficient in a low water temperature range, there is an advantage that a perfect sphere can be easily obtained.

On the other hand, if it is made of metal, the operating efficiency for ice making and ice removal is good, but if the hole aη is made small, the hole αD will close up first during the ice growth process, creating a cavity in the spherical core. Therefore, it is preferable to set 6αη larger than that of synthetic resin.

[Claims] 1. A plurality of hemispherical metal ice-making cups (14) are arranged in a downward-opening bowl shape and connected by a substrate (16), and a cooling pipe (4) is connected to the ice-making cup. (14
), while two ice-making covers (14) are attached to the surface of the ice-making cup (14), each having a spherical surface formed by equally dividing a hemispherical surface of the same type as the ice-making cup (14).
15) and (15), each with a hemispherical surface and an ice cup (1
4) are pivoted to the base plate (16) so as to be able to form spherical surfaces, respectively, and to be able to swing between a closed state forming a hemispherical surface and an expanded state opening when separated. At the same time, a spring force is applied to maintain the closed state during ice making, and each ice making cover (15) is provided with a water injection hole (17) at the bottom where they meet. An ice-making machine characterized in that the ice-making machine is further equipped with a fountain device (10) that directs water into the ice-making cup (14) and injects water into the ice-making cup (14). 2. The spring force applied to the ice-making covers (15), (15) cannot compete with the total weight of the ice balls inside the ice-making cup (14) and the ice-making covers (15), (15) at the time of water separation. (15) The ice making machine according to claim 1, which is strong enough to expand the ice maker.
