This is to prevent the occurrence of problems such as disconnection due to overload.

Along with this, the control unit 200 may determine when de-icing is complete, and control water to be supplied to the ice-making chamber 30 again. Control of the control unit 200 may include controlling the temperature measuring unit 400 ), If the rate of change of the temperature inside the ice-making chamber 30 is greater than or equal to a preset average change rate, or when the temperature inside the ice-making chamber 30 is increased to a preset temperature, for example, 40 degrees or more , It is determined that de-icing is completed, so that the supply of water through the water supply pipe 40 is stopped.

Here, when the controller 200 satisfies any of the above two conditions, that is, a change rate of temperature rapidly increases, or a condition that becomes 40 degrees or more, it is determined that de-icing has been completed, and the water supply control valve 410 By controlling the water supply for ice making through the water supply pipe 40 is re-supplied.

As a result, the ice machine according to the present embodiment divides the summer season and the winter season, so that when the temperature of the water supplied to the summer season is 18 degrees or more, defrosting is performed only with water, and the temperature of the water supplied to the winter season is high temperature when the temperature is less than 18 degrees. By using the gas of the same, it is possible to ensure the de-icing at the right time, and the present invention is equipped with a temperature measuring unit, when the rate of change of the temperature of the gas detected in the state of complete de-icing is more than the average rate, Alternatively, when the temperature of the gas detected through the temperature measuring unit rises to 40 degrees or more, it is determined that de-icing has been completed and the operation for de-icing is stopped, so that it is possible to accurately detect whether de-icing and the start time of the next operation for de-icing.

By connecting the evaporator 13 installed in close contact with the ice making frame 32 of the compressor, the gas compressed in the compressor 11 is condensed while emitting condensation heat by the condensation fan 12a, and then moves to the evaporator 13 Constituting a circulating gas line to evaporate, by installing a bypass line 14 for hot gas movement connected to the evaporator 13 between the compressor 11 and the condenser 12 for de-icing, by controlling the control unit 200 By installing a bypass control valve 15 that is selectively opened and closed, the hot gas compressed in the compressor 11 is not directly condensed from the condenser 12, but is supplied directly to the evaporator 13, and the ice making machine 32 is heated to make ice making. By melting the close contact surface between the ice and the ice making machine 32 iced in the mold 32, the ice is configured to defrost from the ice making machine 31.

The ice defrosted from the ice making frame 32 by the above operation is stored in the ice storage chamber 20 by passing through the discharge door 35 by riding the guide plate 34, and when water is frozen in the storage tank 38, ice is completed. At the same time, the water supply control valve 41 is shut off to stop the supply of water, and the bypass control valve 15 is blocked to coolant gas is condensed in the condenser 12 and supplied to the evaporator 13, and at the same time, the pump P In operation, the water (de-icing water) of the water storage tank 38 is sprayed into the inside of the ice-making frame 32 by the spray nozzle 37 to make ice.

In the process of performing the above operation, the temperature sensor 16 installed on the side where the condensed refrigerant of the condenser 12 is discharged continuously detects the temperature of the condensed refrigerant and the temperature of the refrigerant sensed by the temperature sensor 16 When the temperature is higher than the preset temperature, the condensation fan (12a) is driven to discharge condensation heat and when the temperature of the refrigerant is lower than or equal to the preset temperature, the condensation fan (13) is stopped to perform a refrigeration cycle and the temperature of the refrigerant to be closed is always Try to maintain a certain range of temperature.

When ice flows and deices from the ice making machine 32, the pump P is operated once or twice to spray water from the injection nozzle 36, thereby impacting the ice making machine 32 and making it in the ice making machine 31. Try to freeze the ice that is not being iced.

However, in supplying water to the upper portion of the ice-making frame support plate 33, since the material of the ice-making frame 32 is made of metal, and the material of the ice-making frame support plate 33 is made of plastic, ice is produced as before. When water is supplied to the upper portion of the frame support plate 33, de-icing of the ice-making area A inside the ice-making frame 32 where heat conduction is easily performed can be effectively performed, but the ice-making area inside the ice-making frame support plate 33 Effective de-icing may be difficult due to the material properties for A ').
