Patent attributes
An automatic ice making machine is provided that is capable of modifying an amount of feeding water depending on a temperature of makeup water. The automatic ice making machine is equipped with a deicing timer 42 to keep time of a deicing completion time period T1 in which deicing operation is completed. In addition, in a control means 24, a deicing water longest supply time period U1 is preset, which is a longest time period to supply deicing water in deicing operation. In a case where the deicing water is low in temperature, so that the deicing progresses slowly and thus the deicing completion time period T1 becomes equal to or greater than the deicing water longest supply time period U1, the control means 24 carries out water feeding in a feeding amount of water at low temperature at the time of water feeding. In contrast, in a case where deicing water is high in temperature, so that the deicing is promoted and thus the deicing completion time period T1 becomes shorter than the deicing water longest supply time period U1, the control means 24 carries out water feeding in a feeding amount of water at high temperature, which is more than the feeding amount of water at low temperature, at the time of water feeding.
