A method for controlling a refrigerator includes determining whether an ice bin accommodated in an ice making compartment that receives cold air from the first storage compartment is full of stored ice, determining, by a controller, whether an algorithm that prevents the ice stored in the ice bin from melting needs to be performed upon determining that the ice bin is full, and performing the algorithm.

A refrigerator is configured to enable a user to open doors of the refrigerator easily. The refrigerator performs a method for controlling the doors to prevent from opening due to a malfunction.

A control method for a drawer door of a refrigerator and the refrigerator. The refrigerator comprises a refrigerator body (100), a drawer door (200) mounted in the refrigerator body (100) in a front-back pushed and pulled mode, and a driving mechanism (300) driving the drawer door (200) to move forward and backward. The control method comprises: obtaining a door opening instruction or a door closing instruction; controlling the driving mechanism (300) to drive the drawer door (200) to move forward to open or move backward to close; detecting a resistance borne by the drawer door (200) during the movement; determining whether the resistance is greater than a preset resistance threshold; and if yes, controlling the driving mechanism (300) to stop running to enable the drawer door (200) to stop moving. According to the method, the problem that the drawer door (200) is difficult to open is solved, and the automatic opening and closing process of the drawer door (200) is more controllable.

A refrigerator provides visual information indicating a map of the refrigerator and technical operations of the corresponding regions. The refrigerator includes a voice recognition function using a proximity sensor. The refrigerator has input/output (I/O) management functions for foods stored therein. The refrigerator communicates with a peripheral device over a network.

Provided is a refrigerator and control method for refrigerator and method for opening a refrigerator door. While a user is holding an object in both hands, a door may be automatically and additionally opened using another part of a body other than hands.

A refrigerator and a control method, device and system thereof are provided. The method comprises detecting and confirming that the cumulative running time of a compressor is no less than a running time threshold, and an ice maker is currently in a working state, and controlling the ice maker to perform an defrosting operation after a current ice making period is ended, the running time threshold being a time difference between the defrosting period of the refrigerator and the ice making period of the ice maker. The method allows avoiding defrosting in the ice making period, and therefore, the influence of defrosting on ice making of the ice maker can be reduced, the ice making efficiency and the ice making capacity if the ice maker can be effectively promoted, the ice making period is shortened, energy consumption is reduced, and produce reliability is improved.

Disclosed are a refrigerator diagnostic method and a refrigerator using an artificial intelligence algorithm (AI) and/or machine learning algorithm in a 5G environment connected for the Internet of things. The refrigerator diagnostic method may include determining an installation state of a refrigerator based on a power value of a compressor provided in the refrigerator and the number of revolutions of a cooling fan provided in the refrigerator, when an operating time after initial installation of the refrigerator is less than or equal to a particular value, and determining a malfunction and a cleaning state of the refrigerator based on the power value of the compressor and the number of revolutions of the cooling fan, when the operating time after initial installation of the refrigerator exceeds the particular value.

A defrost or thaw measuring device has a dumbbell or hourglass-shaped rotatable compartment with a cavity, the cavity being partly filled with at least two phase change materials having different melting points. The measuring device may determine the time period of thawing at two or more temperature intervals in the refrigeration space.

A controller within a refrigeration application controls temperature and humidity within a compartment of the refrigeration application. The controller may begin cooling the compartment based on a measured temperature value for the compartment. The controller may delay a starting time of an evaporator fan within the compartment based at least in part on a measured humidity value for the compartment. The controller may also adjust an operating time of a condenser fan based at least in part on the measured humidity value.
