AUTOMATIC ICE MAKER

WIPO Patent Application WO/2005/061974

A1

Separation between ice making plate and an insulation layer and that between the insulation layer and heating means is prevented from occurring to enable an efficient ice making operation. Also, a metallic plate and the heating means are reliably insulated from each other. An automatic ice maker where an ice making member (11) is provided with a vaporizer tube (14) and electrical heaters (H1-HN), wherein, in an ice making operation, a refrigerant is circulated and supplied in the vaporizer tube (14) to cool the ice making member (11) and simultaneously ice making water is supplied to the ice making member (11) to produce an ice block (M), and in an ice removing operation, electricity is conducted in the heaters (H1-HN) to produce heat, melting and removing the ice block (M) from the ice making plate (11). The ice making member (11) is formed by making connections by thermal compression bonding both between a metallic plate (12a) and an insulation layer (12b) and between the insulation layer (12b) and the heaters (H1-HN) with the insulation layer (12b) interposed between the metallic plate (12a), to which the vaporizer tube (14) is connected, and the heaters (H1-HN). Further, in addition to the thermal compression bonding, the external outlines of the heaters (H1-HN) may be positioned inside the insulation layer (12b).
