Publication number: 20240133621Abstract: According to the present disclosure, after a load operation is performed by satisfying a start condition of the load operation, the load operation is terminated when a compartment temperature of a storage compartment satisfies a termination condition when a door is opened or when a temperature change in the storage compartment satisfies the termination condition. Accordingly, excessive power consumption during the load operation may be prevented, and thus power consumption may be improved.Type: ApplicationFiled: November 12, 2021Publication date: April 25, 2024Inventors: Youngseung Song, Min Hyuk Park, Sangbok Choi, Yun Su Cho

Publication number: 20240044568Abstract: In a refrigerator and control method thereof according to the present disclosure, when a load operation is terminated and a normal storage operation is performed, a re-input prevention control is performed to prevent the load operation from being performed even if an operation start condition of the load operation is satisfied. During the re-input prevention control, when a re-input prevention stop condition is satisfied, the re-input prevention control is controlled to be stopped. In this way, it is possible to prevent over-cooling of a first storage compartment, which may be caused by continuous input of the load operation, and respond smoothly to the corresponding load when a large load is input.Type: ApplicationFiled: November 12, 2021Publication date: February 8, 2024Inventors: Youngseung SONG, Min Hyuk PARK, Sangbok CHOI, Yun Su CHO

Publication number: 20230194144Abstract: The present disclosure relates to a refrigerator. The refrigerator according to one embodiment of the present disclosure comprises: an evaporator; a defrosting heater; a temperature sensor; and a controller to control the defrosting heater. The controller is configured to: in response to a defrosting operation starting time arriving, perform a defrosting operation mode including a pre-defrosting cooling mode, a heater operation mode and a post-defrosting cooling mode; perform a continuous operation mode, in which the defrosting heater is continuously on; and when a temperature change rate sequentially increases, decreases and increases again, perform a pulse operation mode, in which the defrosting heater is repeatedly turned on and off. Accordingly, defrosting efficiency may be improved, and power consumption may be reduced.Type: ApplicationFiled: April 21, 2021Publication date: June 22, 2023Inventors: Youngseung SONG, Yunsu CHO

Publication number: 20230175758Abstract: The present disclosure relates to a refrigerator. According to an embodiment of the present disclosure, the refrigerator comprises: an evaporator; a defrost heater; a temperature sensor to sense a temperature around the evaporator; and a controller to control the defrost heater. In response to reaching a defrost operation starting point, the controller is configured to perform a defrost operation mode, perform a continuous operation mode, in which the defrost heater continuously turns on, and a pulsed operation mode, in which the defrost heater switches between on and off, based on the defrost operation mode, wherein in response to performing the pulsed operation mode, the controller is configured to change the ON duration or power level of the defrost heater. Accordingly, defrosting efficiency may be improved, and power consumption may be reduced.Type: ApplicationFiled: April 21, 2021Publication date: June 8, 2023Inventors: Youngseung SONG, Kyongbae PARK, Yunsu CHO, Namsoo CHO, Kyunghun CHA, Sangbok CHOI

Publication number: 20230175757Abstract: The present disclosure relates to a refrigerator. The refrigerator includes an evaporator, a defrost heater, a temperature sensor to detect an ambient temperature of the evaporator, and controller to control the defrost heater, wherein, in response to a defrosting operation start time point arriving, the controller is configured to perform a defrost operation mode including a pre-defrost cooling mode, a heater operation mode, and post-defrost cooling mode, perform a pulse operation mode in which the defrost heater is repeatedly turned on and off based on the heater operation mode, and change a magnitude of cooling power supplied in the post-defrost cooling mode based on an ON period of the defrost heater or a temperature of a cooling compartment in the pulse operation mode. Accordingly, defrosting efficiency and power consumption may be improved, and cooling power after defrosting may be efficiently supplied.Type: ApplicationFiled: April 21, 2021Publication date: June 8, 2023Inventors: Youngseung SONG, Kyongbae PARK, Yunsu CHO, Kyunghun CHA, Sangbok CHOI

Publication number: 20230160625Abstract: The present disclosure relates to a refrigerator. The refrigerator according to an embodiment of the present disclosure comprises: an evaporator; a defrost heater; a temperature sensor to sense ambient temperature around the evaporator; and a controller to control the defrost heater, wherein the controller is configured to: perform a defrost operation mode in a case of reaching a defrosting operation start time point; perform, based on the defrost operation mode, a continuous operation mode in which the defrost heater is continuously turned on, and a pulse operation mode in which the defrost heater is repeatedly turned on and off; and perform the continuous operation mode again after performing the pulse operation mode. Accordingly, defrosting efficiency may be improved, and power consumption may be reduced.Type: ApplicationFiled: April 21, 2021Publication date: May 25, 2023Inventors: Youngseung Song, Kyongbae Park, Yunsu Cho, Sangbok Choi, Namsoo Cho
