Abstract: Disclosed is a voice recognition device and method. According to the disclosure, the voice recognition device, upon failing to grasp the intent of the user's utterance from the original utterance which is divided into a head utterance and a tail utterance, figures out the intent from the head utterance to thereby complete the original utterance and provides the result of voice recognition processing on the original utterance. According to an embodiment, the voice recognition device may be related to artificial intelligence (AI) modules, robots, augmented reality (AR) devices, virtual reality (VR) devices, and 5G service-related devices.

Abstract: An air conditioner may include a compressor that compresses refrigerant; a condenser that condenses the refrigerant; at least one expansion valve that expands the refrigerant; a gas-liquid separator that separates and discharges the refrigerant into gas refrigerant and liquid refrigerant; an evaporator that evaporates the liquid refrigerant discharged from the gas-liquid separator; a refrigerant inflow pipe that connects the expansion valve and the gas-liquid separator; a bypass pipe that connects the gas-liquid separator and the compressor; and a refrigerant discharge pipe that connects the gas-liquid separator and the evaporator. The gas-liquid separator may include a housing in which a portion of the refrigerant inflow pipe, the bypass pipe, and the refrigerant discharge pipe may be disposed, and first and second partition walls disposed in the housing.

Abstract: An air conditioner is provided that may include a compressor that compresses a refrigerant; a condenser that condenses the refrigerant discharged from the compressor; at least one expansion valve that expands the refrigerant passed through the condenser; at least one gas-liquid separation pipe through which the refrigerant passed through the at least one expansion valve flows; a gas-liquid separator, into which the refrigerant passed through the at least one gas-liquid separation pipe is introduced, that separates and discharges the refrigerant introduced into the gas-liquid separator into gas refrigerant and liquid refrigerant; and an evaporator that evaporates the liquid refrigerant discharged from the gas-liquid separator. The gas refrigerant discharged from the gas-liquid separator and the refrigerant passed through the evaporator may be provided to the compressor. The at least one gas-liquid separation pipe may include a first portion that extends lengthwise, and is connected to a refrigerant inflow pipe in which the at least one expansion valve may be installed, and a second portion that extends in a direction crossing a lengthwise direction of the first portion and is coupled to the first portion. At least one of the first portion or the second portion may be connected to the gas-liquid separator.
