Abstract:
A refrigerator includes a compressor, a cold storage medium, a power supply to convert AC power supplied from an outside of the refrigerator, and to receive DC power during interruption of electric power, and a controller to perform a control operation to supply a cooling capacity to an interior of the refrigerator by driving the compressor based on the supplied AC power when no interruption of electric power occurs, and to perform a control operation to supply a cooling capacity to the interior of the refrigerator based on the supplied DC power and the cold storage medium during the interruption of electric power. Accordingly, consumption of electric power during interruption of electric power is reduced.
Abstract:
A refrigerator according to an embodiment of the present invention includes a power input part through which power is input from a UPS device connected to a commercial power source and an auxiliary power source; a voltage sensor configured to sense a voltage of the power input through the power input part; and a control part configured to analyze a voltage signal sensed by the voltage sensor and to determine whether the input power is commercial power or auxiliary power.
Abstract:
A power determining apparatus is disclosed. The power determining apparatus includes a sensor for sensing a current or voltage supplied from a commercial power source or an uninterruptible power supply (UPS), and a controller for analyzing a current or voltage signal sent from the sensor, and determining which one of the commercial power source and the UPS supplies power, based on results of the analysis.
Abstract:
Provided is a refrigerator. The refrigerator may include a power supply unit configured to power the refrigerator using commercial power, a battery coupled to the power supply unit and configured to supply auxiliary power to the refrigerator, a power detection unit coupled to the power supply unit and the battery and configured to detect whether power is being supplied from the power supply unit, a driving unit to provide cold air, and a controller configured to control an operational mode of the driving unit based on the detection at the power detection unit. When the power supply unit is supplying power, the driving unit may be controlled to operate in a normal operation mode, and when the power supply unit is not supplying power, the driving unit may be controlled to operate in a power failure operation mode and to control the power to be supplied from the battery.
Abstract:
Disclosed are a lawn mower robot and a control method for same. A lawn mower robot and a control method for same according to an embodiment of the present invention can sense height information about the height between a lawn and the lower side of the lawn mower robot. The sensed height information is used as supporting data for calculating whether the lawn mower robot has deviated from a preset travel path, as well as the deviation direction. Accordingly, even when a separate sensing means is not provided, whether the lawn mower robot has deviated from the preset travel path is calculated using the height information about the height from the ground, and thus the lawn mower can be returned to the preset travel path.
