6 is a graph showing a temperature change of water or ice contained in the ice making apparatus.

The graph in which the temperature of the water accommodated in the ice making apparatus is changed may be divided into an ice transfer section S1, a water supply section S2, and an ice generation section S3.

After the water is supplied to the ice tray, when the temperature reaches the ice start temperature T1, the ice transfer section S1 may be started. The ribbing start temperature T1 is set to 0 degrees C or less. When the ice transfer section S1 is started, the heater 2110 may be operated to effectively separate the ice from the ice tray 2100. Then, when the set time has elapsed, the rotating unit 2300 is operated to transfer the ice to the ice bucket 300.

When the transfer of ice is completed, water for ice generation is supplied to the ice tray in the water supply section S2.

When water is supplied, the water accommodated in the ice tray 2100 forms ice while being cooled by cold air in the ice generation section S3. When the set temperature is reached by cooling, the ice transfer section S1 may be started.

The operation of the ice making device is based on the premise that the ice is placed in the ice tray 2100 at the ice-making start temperature T1. However, in the operation process of the ice making device 30 there may be a subcooling section (S4) that does not become ice even after the water contained in the ice tray 2100 is lowered below 0 ° C., and a supercooling phenomenon that maintains the water state occurs. .

7 is a diagram illustrating a control relationship of the refrigerator of FIG. 1.

Referring to FIG. 7, the refrigerator 1 may be provided with a controller 50. The controller 50 controls the components of the refrigerator 1, such as the compressor 60, the valve 150, and the like.

The ice maker 30 may be provided with a temperature sensor 140. The temperature sensor 140 may detect a temperature of water or ice contained in the ice tray 2100. For example, the temperature sensor 140 may be located in the ice tray 2100 to detect a temperature of water or ice contained in the ice tray 2100. In addition, the temperature sensor 140 is provided as a non-contact temperature sensor 140 that can sense the temperature in a non-contact manner through a laser, infrared light, etc., the drive housing 2320, the cover portion 2400, the cold air guide portion 2200 In another configuration of the ice making device 30, such as the ice bucket 300 or the inner surface of the case 100, the ice bucket 300 may sense the temperature of water or ice contained in the ice tray 2100.

The valve 150 is positioned on a path through which water is supplied to the ice maker 30, and opens and closes a path through which water is supplied to the ice maker 30. For example, the valve 150 may be located at a point on the water supply pipe 121.

The compressor 60 is provided to be located at one side of the main body 10. The compressor 60 is connected to the evaporator and forms part of the path through which the refrigerant is circulated. The refrigerant heat exchanged in the evaporator is introduced into the compressor (60). The refrigerant introduced into the compressor 60 after absorbing the surrounding heat while evaporating inside the evaporator may be in a gas state or a state in which gas and liquid are mixed. The compressor 60 may compress the introduced refrigerant and then supply the refrigerant. The refrigerant supplied to the evaporator may be condensed in the liquid state in the flow process.

The controller 50 controls the components of the refrigerator 1. For example, the controller 50 has one physical configuration and is located on one side of the refrigerator 1 so that the ice making device 30, the valve 150, the compressor 60, and the other components of the refrigerator 1 are different. Can be controlled. In addition, the controller 50 may have two or more physical configurations, each of which may be located at one point of the refrigerator 1. In addition, a part of the controller 50 may control the ice making device 30, and another part of the controller 50 may control other components of the refrigerator 1. When the controller 50 has two or more physical configurations, the respective portions of the controller 50 may be electrically connected to each other and interlock with each other to perform control.

8 is a flowchart illustrating a step of determining whether the ice making apparatus is in a state of performing ice transfer.

Referring to FIG. 8, the controller 50 determines whether the running time of the compressor 60 is longer than the set time (S100). The running time of the compressor 60 may be calculated from the time when the valve 150 is opened and water is supplied to the ice making device 30. Operation of the compressor 60 may be made intermittently. For example, the controller 50 stops the operation of the compressor 60 when the temperature of the storage chamber 11 is lower than the set temperature, and operates the compressor 60 when the temperature of the storage chamber 11 is higher than the set temperature. The compressor 60 can be controlled. Accordingly, the controller 50 determines whether the accumulation of time at which the operation of the compressor 60 has been reached reaches the set time after the valve 150 is opened to supply water to the ice making device 30. For example, the set time may be set to 30 to 60 minutes.

The controller 50 determines whether the temperature sensed by the temperature sensor 140 is equal to or lower than the icebreaking start temperature T1 (S200), and when it is determined that the temperature detected by the temperature sensor 140 is lower than or equal to the icebreaking temperature T1, the ice bucket 2100 in the ice tray 2100. The rotating unit 2300 of the ice making apparatus is controlled to transfer the ice to the 300 (S300). The ribbing start temperature T1 is set to 0 degrees C or less. The ribbing start temperature T1 may be set to -5 ° C to -13 ° C.

In another embodiment, the controller 50 first determines whether the temperature sensed by the temperature sensor 140 is equal to or less than the icebreaking start temperature T1, and then, after the water is supplied, whether the running time of the compressor 60 is greater than or equal to a set time. Can be determined.

In another embodiment, the controller 50 may omit the determination of the temperature detected by the temperature sensor 140 when the running time of the compressor 60 after the water is supplied is greater than or equal to the set time, and may start the ice-making operation. have.

The subcooling section S4 may occur in the ice generation section S3, and may reach the ice starting temperature T1 in the supercooling state. When the controller 50 controls the pivoting unit 2300 such that the pivoting unit 2300 starts the ribbing operation based on whether the ribbing start temperature T1 is reached, the ribbing operation may be performed in a supercooled state. Thus, even if the ice operation is performed, water or ice is not normally removed from the ice tray 2100. If water is additionally supplied to the ice making device 30 in this state, ice is not made in the desired state in the ice making device 30.

In addition, even when the ice generation section S3 has elapsed, it may not be prevented that the ice making operation is performed in the subcooling section S4. After the water is supplied to the ice tray 2100, the time period during which the ice generating section S3 is performed may vary depending on the operating state of the refrigerator 1.

Specifically, when the cold air supplied to the ice making equipment 30 increases, the time for changing the phase of the water into ice is shortened. When the cold air supplied to the ice making device 30 decreases, the time for changing the phase of the water into ice becomes long. The amount of cold air supplied to the ice making device 30 depends on the running state of the compressor 60 or the running state of the fan 44. The compressor 60 may be controlled to operate in a state where the temperature of the storage compartment 11 is higher than the set temperature. In addition, the fan 44 which flows the cold air of the freezer compartment F to the refrigerating compartment R and the ice making apparatus 30 can be controlled to operate in the state in which the temperature of the storage compartment 11 is higher than set temperature. Accordingly, cold air is supplied to the ice making device 30 according to conditions such as a set temperature of the storage compartment 11, a change of season, and the like, such as a temperature of a space where the refrigerator 1 is located, the number of times the door 20 is opened, and the like. The time for which the state and the ice generation section S3 proceeds varies.

On the other hand, the refrigerator 1 according to an embodiment of the present invention is controlled to start the ice-making operation in consideration of the running time of the compressor 60 and the amount of cold air supplied to the ice making device 30 accordingly. Thereby, starting of the ice breaking operation in the supercooled state is prevented. Specifically, after the ice generation section (S3) is started, if the running time of the compressor (60) has passed the set time, and a sufficient amount of cool air is supplied to the ice making device (30) accordingly, when the subcooling section (S4) occurs Edo water is condensed into ice after passing the subcooling section (S4).
