A refrigerator is provided. The refrigerator includes a main body including a door, a door opening device including a motor, and for opening the door using the motor, a proximity sensor, and a controller, wherein the controller is configured to detect whether an object exists within a first distance from a predetermined area of the refrigerator, identify whether the object is detected during a threshold time range, based on the object being detected during the threshold time range, identify whether the object is detected outside a second distance from the predetermined area, and based on the object being detected outside the second distance, control the motor to open the door.

A refrigerator is provided. The refrigerator includes a main body including a first door and a second door, a door opening device configured to open the first door and the second door, a first proximity sensor disposed adjacent to the first door, a second proximity sensor disposed adjacent to the second door, and a processor, and the processor may control the first proximity sensor and the second proximity sensor to operate alternately, based on sensing data obtained by the first proximity sensor and the second proximity sensor, identify a door close to an external object that approaches within a threshold distance from the refrigerator, and control the door opening device to open the identified door among the first door and the second door.

A refrigerator is provided. The refrigerator includes a body including a door, a door opening device including a motor, and configured to open the door through a rotation of the motor, a first sensor configured to sense an opening of the door, a second sensor configured to sense a position of the door, and a processor is included, and the processor is configured to control, based on a user command for the opening of the door being obtained, the motor to rotate at a first speed, control, based on the opening of the door being sensed by the first sensor, the motor to rotate by reducing speed in stages to a second speed which is slower than the first speed, and control, based on a position of the door being sensed in a first position by the second sensor, the motor to open the door to a second position by rotating at the second speed.

Described herein is an electric motor assembly for an environmental control system. The electric motor assembly includes a fan configured to rotate to circulate air within a controlled environment chamber of the environmental control system, and an electric motor coupled to the fan and configured to rotate the fan. The electric motor includes a motor controller configured to receive a braking control signal from a sensor associated with the controlled environment chamber. The braking control signal indicates an entrance to the controlled environment chamber is about to be opened. The motor controller is also configured to initiate braking the electric motor in response to receiving the braking control signal.

An artificial intelligence device for providing a speech recognition function includes a memory configured to store a basic wake-up word used to activate the speech recognition function of the artificial intelligence device and an additional wake-up word used to control operation of the artificial intelligence device, a microphone configured to receive a speech command, and a processor configured to determine whether a current situation is an additional wake-up word recognition situation when the basic wake-up word is recognized from the speech command and perform operation corresponding to the remaining command excluding the basic wake-up word from the speech command upon determining that the current situation is the additional wake-up word recognition situation.

A refrigerator including a main body including a storage room, a door coupled to the main body and rotatable in front of a side of the storage room, and including a display on a front surface of the door, a camera disposed to capture the storage room, and a processor configured to acquire an augmented-reality object corresponding to a food included in an image captured by the camera using a trained artificial intelligence model, to control the display to display the acquired augmented-reality object and the captured image as being overlapped with each other, and based on a user input being acquired while the acquired augmented-reality object is displayed, to provide a response to the user input based on the acquired augmented-reality object. The refrigerator can utilize an artificial intelligence model trained according to at least one of machine learning, neural network or deep learning algorithm.

A refrigerator is configured to enable a user to open doors of the refrigerator easily. The refrigerator performs a method for controlling the doors to prevent from opening due to a malfunction.

Provided is a refrigerator and control method for refrigerator and method for opening a refrigerator door. While a user is holding an object in both hands, a door may be automatically and additionally opened using another part of a body other than hands.
