Claims

[Scope of utility model registration request]

Operation control used in the ice making machine that supplies deicing water from the water supply valve 26 to the ice making section 1 during the deicing process and also supplies hot gas to the evaporator 2 connected to the ice making section 1 in a heat exchange relationship. In the apparatus, the water supply valve 26 is connected to the normally closed contact 24 of a timer 23 that controls the opening time of the water supply valve 26, and the normally open contact 25 of the timer 23 is connected to the supply of hot gas to the evaporator 2. An operation control device for an ice making machine, characterized in that a hot gas valve 15 for controlling the ice making section 1 is connected to a temperature-sensitive de-icing detection switch device 18 which is turned on when detecting the detachment of ice from the ice making section 1.
