O Utility Model Registration Scope of Claims In an ice making system that produces block ice while stirring the ice making water in the ice making water tank with air, the starting switch is connected to a set coil of a keep relay. A block ice manufacturing apparatus comprising: a keep relay, an air pump, and a compressor connected to each other so that the air pump and compressor are operated by energizing the reset coil by turning on the start switch.

Claims (1)

[Scope of utility model registration request] An air pipe is provided in an ice-making water tank to produce block ice while stirring ice-making water with air, an air pump for supplying air to the air pipe, a compressor provided in the freezing section, An ice making thermo that controls *vyc of this compressor, a deicing heater provided in the ice making water tank, a deicing thermo that controls the energization of the deicing heater, and a deicing thermo that controls the activation of the compressor and air pump. It is equipped with a keep relay unit that memorizes the state and a start switch that sets the keep relay unit, and when the keep relay unit is set by actuation of the start switch, the compressor and air pump are driven to enter the ice making process, and the ice making process is started. When the ice making is completed by the operation of the thermostat, the keep relay unit is reset to stop driving the compressor, and the deicing heater is energized via the deicing thermostat to enter the deicing process.
Furthermore, the block ice manufacturing method is characterized in that the air pump is continuously operated to stir the ice making water, and when the electricity is re-energized after a power outage, the ice making process is automatically continued by the integrated operation of the keep relay.
