To cause an ice making frame to be easily moved away from an ice making plate during an ice removing operation and at the same time to perform a smooth removal of ice blocks produced at the ice making plate.
An ice making plate 11 is cooled and ice making water is supplied to the front surface of it with an ice making frame 12 having demarcated ice making chambers 17 located near the front surface of the ice making plate 11. Ice is produced at the front surface of the ice making plate 11 while a growth of the ice at the ice making chamber 17 is being restricted. When the fact that some rectangular ices are formed in the ice making chamber 17 is detected, supplying of ice making water is stopped and at the same time tap water of normal temperature is flowed to the outer surface of the ice making frame 12 and supplied into an ice making water tank 22 while cooling of the ice making plate 11 is being continued. When the fact that a desired amount of tap water is supplied into the ice making tank 22 is detected, supplying of tap water is stopped and then the ice making frame 12 is moved away from the ice making plate 11 while the ice blocks are being adhered to the ice making plate 11. Then, the ice making plate 11 is heated to cause the rectangular ices to be melted and removed from the ice making plate 11.
