## Abstract

An ice maker has an ice-making vessel having a cylindrical shape, a cooling means, a block ice making mold which is placed inside, and an agitator. The mold includes a main mold body having a plurality of connected L-shaped plates projected radially outward from the central axis; a base plate which is joined to each L-shaped plate, and the top side of the L-shaped plates form a screw insertion part of the mold body such that the agitator fits between the L-shaped plates at a second end of the central axis.

## Claims

### Claim 1

An ice maker comprising:
an ice maker main body comprising:
an ice-making vessel having a cylindrical shape with a closed bottom; and
cooling means which cools the interior of the ice-making vessel from outside;
a block ice making mold which is placed inside the ice-making vessel; and
an agitator, an agitating screw side of which is inserted into the ice-making vessel along a central axis of the ice-making vessel, wherein
the block ice making mold includes:
a main mold body which is formed of a plurality of L-shaped plates connected to each other along one side of each of the L-shaped plates serving as a central axis, the each L-shaped plate being projected radially outward from the central axis; and
a base plate which is joined to the each L-shaped plate at one end of the central axis, and
the top side of said L-shaped plates forming a screw insertion part in the mold body such that said agitator fits between the L-shaped plates at a second end of the central axis.

### Claim 2 (depends on 1)

The ice maker according to claim 1, wherein
the block ice making mold is formed by including a separation shelf inserted between mutually adjoining L-shaped plates, and
the separation shelf includes a plurality of fan-shaped horizontal plates arranged at predetermined intervals and a rectangular vertical plate arranged at a predetermined interval, the horizontal and vertical plates together forming a lattice shape.

### Claim 3 (depends on 1)

The ice maker according to claim 1, wherein the ice-making vessel includes heating means along an outer periphery of the ice-making vessel.

### Claim 4 (depends on 2)

A method of manufacturing fan-shaped molded ice, the method using the ice maker according to claim 2, wherein
the molded ice has a predetermined thickness and becomes wider from one end side toward another end side.

### Claim 5 (depends on 2)

A method of manufacturing fan-shaped molded ice, the method comprising:
manufacturing ice by using the ice maker according to claim 2;
taking out a block ice making mold from an ice-making vessel;
taking out a separation shelf from the block ice making mold; and
separating the fan-shaped molded ice from the separation shelf by bending the separation shelf being taken out.
