A system includes a door sensor that provides a status of whether a door of a refrigeration system is open or closed, a temperature sensor that measures a temperature of a food compartment of the refrigeration system, a power sensor that measures an amount of power consumed by the refrigeration system, and a compressor sensor that provides acoustic data about a compressor of the refrigeration system. The system further includes a remote computing system configured to send an alert indicating that the refrigeration system needs servicing when the temperature of the food compartment of the refrigeration system is determined to be above a predetermined temperature while: the door of the refrigeration system is closed, the amount of power consumed by the refrigeration system is within a predetermined power range, and acoustic signals of the compressor of the refrigeration system are within a predetermined acoustic range.

A refrigerator may include a cabinet, and a drawer provided with a front panel and a storage bin provided at a rear of the front panel, the front panel being provided so that the open front portion of the storage chamber is opened and closed, and the storage bin being received in a storage chamber. The refrigerator may also include a deodorizing case including an upper end part provided on an inner surface of the storage bin, and a lower end part provided on an outer surface of the storage bin. Additionally, a deodorizing member provided in an inner part of the deodorizing case to remove an odor of the storage chamber.

A refrigerator having a first storage compartment having a first storage space defined therein, a door disposed on the first storage compartment to open and close the first storage space, a drawer-receiving portion defined in the first storage space; a storage drawer configured to be extendable from and retractable into the drawer-receiving portion, and an actuator disposed on a bottom face of the drawer-receiving portion, wherein the actuator is configured to move the storage drawer in an extended direction as the storage drawer is pressed in a retracted direction.

Disclosed herein is an electronic apparatus and method capable of identifying a state of an object. The electronic apparatus includes a light-emitting diode array configured to transmit light beams having different wavelengths, a photodiode array configured to receive the light beams, a display, and a processor configured to control the light-emitting diode array to transmit the light beams having the different wavelengths toward an object, identify a state of the object based on intensities reflected on the object according to the light beams having the different wavelengths that are received by the photodiode array, and display information about the state of the object on the display.

A refrigerator includes a main body having a storage compartment; an inner door rotatably provided at the main body; and an outer door configured to open and close the storage compartment together with the inner door and rotatably provided at the inner door, wherein the inner door includes a connector seating portion disposed at an upper portion of the inner door and configured to connect a first electric wire extending from the main body to the inner door to a second electric wire extending from the outer door to the inner door. Connections between the electric wires are improved so as not to be influenced by the inner and outer doors such that durability of the electric wires can be improved.

A refrigerator including: a main body having a storage room; a door opening and closing the storage room; an electric box to accommodate a printed circuit board; and a guide case to accommodate the electric box, provided on a top surface of the main body, and including a guide rail formed to extend along a front-rear direction of the guide case to guide a movement of the electric box along the front-rear direction of the guide case.

A refrigerator includes a cabinet, a cooling module including a compressor, a condenser, an expansion valve, and an evaporator, and attachable to or detachable from the cabinet so that the cooling module is removably mounted to the cabinet, an electronic device arranged in the cabinet, and an electrical box configured to be electrically connected to the electronic device and the compressor, receive power from outside and supply the received power to the electronic device and the compressor.

An actively heated or cooled cup or mug has a body with a chamber that can receive and hold a beverage and a heating or cooling system disposed in a cavity below the chamber. The heating or cooling system has a heating or cooling element to actively heat or cool the chamber, power storage devices, and circuitry that controls the operation of the heating or cooling elements. A sensor can detect a presence of a liquid in the chamber, the circuitry configured to turn on power to the heating or cooling elements after said liquid is detected and further configured to automatically turn off power to the heating or cooling elements upon receiving a signal indicating that the liquid in the chamber has dropped below a predetermined liquid level or been depleted completely.

A refrigerator includes: a main body forming a storage room; a display positioned on a bottom of the storage room and including a display board; a separating wall extending from the bottom of the storage room toward the display and forming a board accommodating space for accommodating the display board, the separating wall is configured to partition the board accommodating space from a water collecting space positioned between the bottom of the storage room wall and the display.

The present disclosure relates to the technical field of big data analysis, and discloses a method for video recommendation. The method includes: determining a first reference video according to a watching history of a user; determining a collection of recommended videos according to the first reference video; selecting a second reference video from the collection of recommended videos, where videos not selected in the collection of recommended videos are used as candidate videos; and determining recommended videos according to the similarity between the candidate videos and the second reference video. According to the method, a collection of recommended videos is determined according to a watching history of a user, reference videos are selected from the collection of recommended videos, and then recommended videos are determined according to the reference videos, so that the recommended videos are more customized and targeting, matching user requirements and enabling a better user experience.
