Claims (1)

[Scope of utility model registration request] Means 3 for detecting the ice-making plate temperature, means 5 for digitally converting the ice-making plate temperature, means 6 and 7 for setting the desired ice thickness, and calculating and storing a predetermined value proportional to the square of the desired ice thickness. After entering the ice-making cycle in response to the ice-making start signal, the digitally converted ice-making plate temperature is read at regular intervals during the ice-making cycle, and the temperature is read when the ice-making plate temperature falls below 0°C. 1. A falling type automatic ice maker comprising means (CPU) for generating an ice making completion signal when the integral value reaches the predetermined value.
