A fabric treatment apparatus including a steam spray device for heating water to generate steam and for spraying the generated steam into a space in which fabric is received and a water supply valve for adjusting flow of water supplied to the steam spray device to generate steam. A control method of the fabric treatment apparatus including controlling the water supply valve to be repeatedly opened and closed according to a first pattern and controlling the water supply valve to be repeatedly opened and closed according to a second pattern, the second pattern supplying a larger amount of water than in the first pattern for the same time period.

The laundry treatment machine, absent a position sensor to sense the rotor position of a motor, includes a driving unit having an DC/AC inverter, an voltage detection unit to detect output voltage, and an inverter controller to control the inverter. The output voltage detection unit includes a plurality of resistors connected between the inverter and the motor and a comparator to compare voltage detected by some of the resistors with reference voltage and to detect pulse width modulation (PWM)-based output voltage. The voltage detection unit outputs the PWM-based output voltage output from the comparator to the inverter controller in a first mode in which at least one switching device of the inverter is turned on. The voltage detection unit outputs voltage detected by other some of the resistors to the inverter controller in a second mode in which all switching devices of the inverter are turned off.

This information processing system comprises an information station inside a store, a washing machine, and a user terminal operated by a user, wherein, when the information station detects that the user U has visited the store, the information station executes control to display a QR code for transmitting a store-visit coupon to the user terminal. The washing machine displays an advertisement, and also, when the washing machine detects that the user has used the washing machine, the washing machine executes control to display a QR code for transmitting a usage coupon to the user terminal. The user terminal acquires information indicated by the QR code displayed on the information station and information indicated by the QR code displayed on the washing machine.

A remote controllable laundry processing device includes: a cabinet main body including a door, a sensor unit configured to sense a locked state of the door, a manipulation unit provided for user input, a remote control setting unit configured to control the laundry processing device based on an external terminal, a controller configured to control an operation of the laundry processing device, and a communication unit configured to send the controller an input signal from the external terminal. The controller is configured, based on the door being in the locked state and regardless of whether a remote control has been set by the remote control setting unit, to control the laundry processing device in response to a first input signal from the manipulation unit and a second input signal from the external terminal and each of the first input signal and the second input signal is a pause signal.

An artificial intelligence apparatus determines whether a washing option in a washing course according to the input of a user is changed when input of the user is received, and collect use history information when the washing option is changed. In addition, the artificial intelligence apparatus inputs the collected use history information to an option resetting model to acquire a second washing option for resetting the washing course, and resets the washing option included in the washing course according to the second washing option.
