Abstract: A system for controlling a conveyor in a virtual environment includes a twin model module comprising control logic and configured to virtualize a control system for conveyors installed in a factory. The system also includes a digital factory module configured to virtualize the conveyors installed in the factory and create a virtual factory model controlled by the twin model module. A virtualized conveyor includes multiple paths formed by segmenting the conveyor based on joints. The twin model module is configured to control transportation routes of products based on the joints.

Abstract: A digital twin system includes multiple twin model modules and multiple digital factory modules. Respective ones of the multiple digital twin system models comprises control logic and are configured to virtualize respective control systems for respective ones of multiple factories. Respective ones of the multiple digital factory modules are configured to virtualize respective ones of the multiple factories and are controlled by respective ones of the multiple twin model modules to create a virtual factory model. The digital twin system further includes a simulator module configured to manage the multiple twin model modules.

Abstract: An oven that has an improved structure so that the convenience of use and the energy efficiency may be improved includes a casing that has a front panel, a cooking chamber that is provided inside the casing, a door that is rotatably disposed in the casing so as to open and close the cooking chamber, and has a frame, and an individual door that is rotatably provided in the frame so as to open and close an opening provided in the frame.

Abstract: A refrigerator having an operation lever for a dispenser includes first and second levers interconnected to perform respectively different functions. At least one of the first and second levers is moved relative to the other one. Accordingly, the operability and the aesthetic appearance of the refrigerator may be improved.

Abstract: A refrigerator including an extractable container, and a conveying unit formed in an inner space of a vertical wall of the extractable container. The conveying unit includes a guide part to guide the movement of a partition member that divides a storage space of the extractable container, and a fixing part to restrict the movement of the partition member.

Abstract: A refrigerator having an intermediate storage compartment, which has an improved structure of a return flow passage to return cold air from the intermediate storage compartment. The refrigerator includes a first evaporator to supply cold air to an upper storage compartment, a second evaporator to supply cold air to a lower storage compartment, a cold air supply duct to supply cold air generated at the second evaporator to an intermediate storage compartment, and a curved section formed at a top of the intermediate storage compartment to uniformly distribute the cold air supplied via the cold air supply duct in the intermediate storage compartment. The refrigerator also includes a cold air return duct to return cold air from the intermediate storage compartment, and an ice-making cold air return duct to return cold air from an ice maker. The cold air return duct is joined with the ice-making cold air return duct.
