Title:
OPERATION METHOD OF ICE MAKING MACHINE
Document Type and Number:
Japanese Patent JP2012229864
Kind Code:
A
Abstract:
To prevent operation stop due to malfunction of a refrigerant detecting section.
A control means C confirms whether a detection signal from a refrigerant detecting sensor S has been received or not when a waiting time WT has elapsed after the start of receiving the detection signal from the refrigerant detecting sensor S. When the detection signal from the refrigerant detecting sensor S has been received even if the waiting time WT has elapsed after the start of receiving the detection signal from the refrigerant detecting sensor S, the control means C determines that the refrigerant is leaking from a freezing mechanism E, and controls a cooling fan 34 for forcibly cooling a condenser 31 to operate continuously.
