An apparatus for cooling bottled beverages may include an open-topped vessel defining a bottle chamber. The vessel may have a tubular wall and a base. The apparatus may further include a cooling device in thermal communication with the base of the vessel and with a heat exchanger. The apparatus may also include a tubular housing surrounding the vessel and enclosing the cooling device and the heat exchanger. Additionally, the apparatus may include a fan configured to provide an air flow along an airflow path. The airflow path may extend from an inlet of the housing, across the heat exchanger, to an outlet of the housing.

A refrigerator includes a cabinet configured to have an inner case in which a storage chamber is formed, a cooler configured to cool the storage chamber, a heating device configured to be spaced apart from the cooler and heat the storage chamber, a circulation fan configured to circulate air in the storage chamber, and a controller configured to operate the circulation fan when the heating device is operated.

A refrigerator includes: a main body having a storeroom for storing a food item; a shelf plate arranged in a storeroom, the shelf plate on which a food item is put; a door that opens and closes a side of the storeroom; a camera arranged on an inner surface of the door, the camera takes an image of an inside of the storeroom; a camera moving device that moves the camera in a vertical direction. The camera moving device stops the camera at one or more points for each of between the shelf plates located adjacent to each other, and between an inner surface of a top edge of the storeroom and the shelf plate located adjacent to the inner surface of the top edge of the storeroom, and the camera takes an image each time when the camera moving device stops moving the camera.

A compressor includes a compression mechanism, a casing, and a temperature detector. The compression mechanism includes a rotation axis. The casing accommodates the compression mechanism. The casing includes a compression mechanism contact portion. The compression mechanism is in contact with an inner surface of the compression mechanism contact portion. The temperature detector is attached to an outer surface of the compression mechanism contact portion and is configured to sense temperature of the compression mechanism contact portion.

A method of providing information about an object in a refrigerator is provided. The method includes: obtaining, using a camera, an image of a plurality of objects stored in the refrigerator; displaying the image on a display of the refrigerator; receiving a first user input indicating a first object from among the plurality of objects included in the image; and displaying a substitute image of the first object on the display based on the first user input.

The application discloses a method for managing food in a refrigerator, including the steps of recognizing the type and quantity of the food placed in the refrigerator according to an image shot by an external camera of the refrigerator; determining a position of the food placed in the refrigerator according to images shot by internal cameras of the refrigerator; generating an AR label for recording information of the food with regard to the food placed in the refrigerator; displaying the AR label of the inquired food after receiving a food query request from a user; wherein the information of the food at least includes the type, quantity and position of the food; and displaying the images shot by the internal cameras in real time after receiving an image viewing request from the user. With the adoption of the application, the food in the refrigerator can be managed more efficiently.
