A method for notifying a user of a disembarkation time by a user equipment (UE) is disclosed. Information about a departure station and information about a destination station are detected not only using at least one of Wi-Fi information and location information collected in an entry station, but also using a station pool. A preceding station located before a disembarkation station is detected not only using a subway line map, but also using at least one of Wi-Fi information and location information collected by the UE on the basis of the detected destination station information. A disembarkation time at a transfer station or at a destination station is pre-notified the user on the basis of the preceding-station recognition time. Therefore, it is possible to pre-notify a user of disembarkation time information at a transfer station and a destination station on a subway route through 5G network.

Method for notification to disembark and user equipment

The present disclosure relates to a laundry treatment machine. The laundry treatment machine according to an embodiment includes a coupling configured to transfer the driving force of a driving motor to the washing shaft or the dewatering shaft; a stopper engaged with the coupling and anchoring the dewatering shaft; a clutch motor configured to move the coupling; a ball stud protruding from the stopper toward the coupling and having a ball disposed at one end of the ball stud; and a clutch lever having a ball housing for receiving the ball of the ball stud and configured to move the coupling by the operation of the clutch motor.

Laundry treatment machine

According to the present invention, a heat exchanger comprises a plurality of coolant tubes and a coolant guide having a coolant flow path through which the plurality of coolant tubes communicate with each other, wherein the coolant guide includes a plurality of plates facing each other, wherein the pair of plates, respectively, include coolant flow path units formed facing each other, the coolant flow path unit forming the coolant flow path, and wherein the pair of plates, respectively, further include joining parts that come in surface contact with each other. Accordingly, the number of parts of the coolant guide may be minimized, and the structure of the heat exchanger may be simplified.

Heat exchanger

According to the present invention, a heat exchanger comprises a plurality of coolant tubes; a plurality of fins contacting the plurality of coolant tubes, wherein each of the plurality of fins comprises: a plurality of fin parts spaced apart from each other; an upper fin part connecting part connecting respective upper portions of the plurality of fin parts with each other, the upper fin part connecting part contacting one of the plurality of coolant tubes; a lower fin part connecting part connecting respective lower portions of the plurality of fin parts with each other, the lower fin part connecting part contacting another one of the plurality of coolant tubes; an upper opening formed at an upper portion of each of the plurality of fin parts; a lower opening formed at a lower portion of each of the plurality of fin parts; an upper protrusion protruded from an upper portion of each of the plurality of fin parts, the upper protrusion contacting the first coolant tube; and a lower protrusion protruded from a lower portion of each of the plurality of fin parts, the lower protrusion contacting the second coolant tube. Accordingly, the present invention provides increased productivity without the need of a separate pipe expanding process.

An air conditioner is provided. The air conditioner may include a compressor, a condenser, an expansion device and an evaporator. The condenser or the evaporator may include a heat exchange tube formed of an aluminum material and allowing refrigerant to flow therein, and a fin connected to the heat exchange tube, the fin being formed of the same metal material as that of the heat exchange tube so as to prevent potential corrosion of the heat exchange tube.

Air conditioning system having an aluminum heat exchanger and an aluminum/copper coupling

A motor control apparatus and method are provided. The motor control apparatus may include a power supply device supplying power to a motor, a power control device selectively blocking current supplied to the motor depending on whether or not the current supplied from the power supply device to the motor is greater than a reference current value, a controller that controls an intensity of the current supplied from the power supply device to the motor, and a load torque detector that detects a load torque generated by the motor as the motor rotates. The controller controls a maximum value of the current to be supplied to the motor so that the maximum value is less than the reference current value when the maximum value of the load torque detected by the load torque detector is greater than a maximum motor output due corresponding to the reference current value.

Motor control apparatus and method

An air conditioner is provided. A location of, an angle between, or a distance between, a heat exchanger and a blower may be varied based on whether or not the air conditioner is operating. A number of drivers for moving the heat exchanger and/or the blower may be reduced and reliability of the driver be enhanced. Size of the air conditioner may be reduced, and efficiency may be improved.

Air conditioner with rotating heat exchanger

An indoor unit of an air conditioner is provided. A width of the indoor unit of the air conditioner may be varied based on whether or not the indoor unit of the air conditioner is operated.
