The present disclosure relates to a refrigerator. The refrigerator according to an embodiment of the present disclosure includes: a compressor configured to compress a refrigerant; an evaporator configured to perform heat exchange using the refrigerant compressed by the compressor; an RF output device configured to output an RF signal to the evaporator for removing frost on the evaporator; and a controller configured to control the RF output device, wherein the controller is configured to: based on the RF signal, control the frost to phase change into a liquid by heat radiated from a plurality of metal fins of the evaporator; and after the phase change, control temperature of the phase changed liquid to increase by a water molecule movement based on the RF signal. Accordingly, defrosting may be performed using the RF signal.

Refrigerator

A refrigerator comprising a fan to operate for supplying cold air to a cooling chamber; an RF output device disposed in the cooling chamber, and for outputting an RF signal into a cavity in the cooling chamber; and a controller for controlling the RF output device, wherein the controller is configured to output the RF signal to goods in the cavity, and to operate in a first section in which temperature of the goods falls, and a second section in which the temperature of the increases after the first section and maintains, wherein when the RF output device operates, a temperature of the cavity is higher than a temperature of other area in the cooling chamber. Accordingly, the freshness of the goods in the refrigerator can be maintained by using the RF signal.

An artificial intelligence cooking device includes a plate including a heater configured to heat ingredients in a cooking vessel placed on the plate; a vibration sensor disposed below the plate configured to detect a vibration signal of the ingredients in the cooking vessel transmitted through the plate; and a processor configured to determine, via an artificial intelligence model having learned properties of the vibration signal, whether or not the ingredients in the cooking vessel are boiling based on the detected vibration signal provided to the artificial intelligence model and the learned properties of the vibration signal; and output information indicating whether or not the ingredients are boiling based on the determination.

Artificial intelligence cooking device

A refrigerator equipped with a door that becomes transparent as necessary to make the interior thereof visible is disclosed. The refrigerator includes a cabinet having a storage compartment defined therein, a lighting device for illuminating the interior of the storage compartment, a door, which is hingedly coupled to the cabinet to open and close the storage compartment, and has an opening and a panel assembly including a front panel disposed on the front surface thereof, a sensor for detecting sound waves, which are generated by a knock input applied to the door and are transmitted through the front panel, and a controller for controlling the lighting device to allow light to be transmitted through the panel assembly, thus making the storage compartment visible from outside the door through the opening when a predetermined knock input is detected.

The refrigerator includes a cabinet having a storage compartment therein, an illumination device for illuminating the interior of the storage compartment, a door hinged to the cabinet for opening and closing the storage compartment, the door having an opening formed therein and a panel assembly having a front panel provided at the front thereof, a knock sensor module including a microphone module for sensing a sound wave generated by knock vibration applied to the door and a module microcomputer for determining whether the knock vibration is a predetermined knock based on the sensed sound wave, and a controller provided separately from the module microcomputer for receiving a knock-on signal from the module microcomputer and operating the illumination device such that light is transmitted through the panel assembly, whereby the interior of the storage compartment can be seen from outside the door.

A refrigerator may include: a communication device, an object detection sensor for sensing an object positioned within a predetermined region around the refrigerator door; and a controller for controlling the refrigerator to operate in a specific mode based on a connected state between the communication network and preset mobile terminals. If an object sensing signal is received from the object detection sensor in the specific mode, the controller may send a notification to at least one of the preset mobile terminals through the communication network.

Refrigerator and home automation system having the same

A refrigerator may include a body having a freezing chamber and a refrigeration chamber, a cooling circuit for cooling the freezing chamber and the refrigeration chamber, and a power source for supplying power to the cooling circuit. The refrigerator may further include a thermosyphon provided between the freezing chamber and refrigerating chamber. A control circuit may be connected to the thermosyphon to control a flow of refrigerant in the thermosyphon. The control circuit may include a valve provided on a circulation path of the thermosyphon, a electrical power storage device connected between the power source and the valve, and a switching circuit provided between the valve and the electrical power storage device. When the power source does not supply power to the cooling circuit, the control circuit may operate the thermosyphon using power stored in the electrical power storage device.

Refrigerator, thermosyphon, and solenoid valve and method for controlling the same

A home appliance and an operating method thereof are disclosed. The appliance includes an audio output unit, a communication unit to perform pairing with a mobile terminal and to receive audio data and information data from the mobile terminal after the pairing is completed, and a controller to perform control to output the received audio data through the audio output unit. Accordingly, audio data received from a mobile terminal is output.
